25 pointer member of the bidi iterator, since no window is pertinent
28 2013-06-08 Eli Zaretskii <eliz@gnu.org>
30 * bidi.c (bidi_fetch_char): Accept additional argument, the window
31 being displayed, and pass it to compute_display_string_pos.

103 Don't highlight when mouse-highlight is nil.
104 (note_mouse_highlight): When mouse-highlight is nil, don't return

537 * insdel.c (insert_1_both): Document the arguments, instead of
538 referring to insert_1, which no longer exists.
540 * xdisp.c (message_dolog): If the *Messages* buffer is shown in
541 some window, increment windows_or_buffers_changed, so that
542 *Messages* display in that window is updated. (Bug#14408)
544 * w32.c: Include epaths.h.

640 * xterm.h (GTK_PREREQ): New macro.
641 All simple uses of GTK_MAJOR_VERSION and GTK_MINOR_VERSION changed
642 to use this macro instead, for consistency and clarity.
644 2013-05-08 Eli Zaretskii <eliz@gnu.org>
646 * xdisp.c (row_for_charpos_p): New function, with code of
647 cursor_row_p, but accepts an additional argument CHARPOS instead
648 of using a hardcoded PT.
649 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
650 (row_containing_pos): Call row_for_charpos_p instead of partially
651 doing the same. Fixes cursor positioning under longlines-mode
652 when longlines-show-effect includes more than one newline, when
653 moving the cursor vertically up.
655 2013-05-08 Juanma Barranquero <lekktu@gmail.com>
657 * makefile.w32-in (ACL_H): New macro.

673 * unexelf.c: Don't assume ElfW (Half) fits in int.
674 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
675 when dealing with ElfW (Half) values, since they can exceed 2**31
676 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
677 (entry_address): Omit unused NUM arg. All uses changed.
679 2013-05-07 Juri Linkov <juri@jurta.org>
681 * callint.c (Fcall_interactively): Set `visargs[i]' for code 'n'

696 * xfns.c: Move misplaced ifndef USE_GTK from previous checkin.
698 2013-05-07 Paul Eggert <eggert@cs.ucla.edu>
700 Static checking by GCC 4.8.0.

702 (x_get_monitor_for_frame, x_make_monitor_attribute_list)
703 (x_get_monitor_attributes_fallback)

708 (x_get_monitor_attributes_fallback): Omit unused locals.
709 (x_get_monitor_attributes_xinerama, Fx_display_monitor_attributes_list):
710 Use double, not float, to avoid mixed-mode floating point arithmetic.

713 Jan Djärv <jan.h.d@swipnet.se>
715 * Makefile.in (XRANDR_LIBS, XRANDR_CFLAGS, XINERAMA_LIBS)
716 (XINERAMA_CFLAGS): New macros.
717 (ALL_CFLAGS, LIBES): Use them.
719 * xfns.c: Include <X11/extensions/Xrandr.h> if HAVE_XRANDR, and
720 include <X11/extensions/Xinerama.h> if HAVE_XINERAMA.
721 (Qgeometry, Qworkarea, Qmm_size, Qframes, Qsource): New variables.
722 (syms_of_xfns): DEFSYM them.
723 (struct MonitorInfo): New struct.

726 (x_get_monitor_attributes_xrandr, x_get_monitor_attributes)
727 (x_get_monitor_attributes_xinerama): New functions.
728 (Fx_display_monitor_attributes_list): New primitive.
729 (syms_of_xfns): Defsubr it.
731 * xterm.h (x_display_info): Add Xatom_net_workarea and
732 Xatom_net_current_desktop.
734 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
735 and dpyinfo->Xatom_net_current_desktop.
737 2013-05-06 Eli Zaretskii <eliz@gnu.org>
739 * xdisp.c (pos_visible_p): Use the special code for finding the
740 beginning of a display property or overlay for any "replacing"
741 display property, not just for display strings. This solves
742 incorrect reporting of position by posn-at-point. (Bug#14241)
744 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
746 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
747 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
748 Verify that ElfW (Half) fits in int.
749 (fatal): Use same signature as lisp.h.
750 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
751 configure and build with -DUNEXELF_DEBUG without worrying about
752 other modules that use DEBUG.
753 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
754 possibly-wide integers now uses it instead of plain fprintf.
755 (entry_address): New function, which avoids problems with 32-bit
756 overflow on 64-bit hosts.
757 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
758 (round_up): Don't assume the remainder fits in int.
759 (find_section): Use bool for boolean. Simplify debug code.
760 (unexec): Don't assume file sizes fit in int or size_t.
761 Omit unnecessary trailing newline in 'fatal' format.
762 Use strerror rather than outputting decimal error number.
763 Remove unused code when emacs is not defined;
764 this file relies on Emacs now.
765 Don't assume e_phnum and e_shnum are positive.
767 * regex.c: Fix problems when DEBUG is defined.
768 (extract_number, extract_number_and_incr): Define regardless of
769 whether DEBUG is defined; that's simpler and makes the code less
770 likely to go stale in the normal case when DEBUG is not defined.
771 Return int rather than taking an int * arg. All callers changed.
772 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
773 Remove, replacing with ...
774 (DEBUG_PRINT): New macro. All callers changed.
775 (DEBUG_COMPILES_ARGUMENTS): New macro.
776 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
777 (print_compiled_pattern, print_double_string) [DEBUG]:
778 Use prototype rather than old-style definition.
779 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
780 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
781 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
782 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
783 Don't assume ptrdiff_t, size_t, and long are the same width as int.
784 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
785 This matters only when DEBUG is defined.
787 2013-05-05 Eli Zaretskii <eliz@gnu.org>
789 * xdisp.c (set_iterator_to_next): Set the
790 ignore_overlay_strings_at_pos_p flag only if we are _really_
791 iterating over an overlay string, as indicated by the
792 current.overlay_string_index member. (Bug#14306)
794 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
796 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
797 to where it is used, to avoid autorelease issues (Bug#14050).
799 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
801 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
802 * fileio.c (syms_of_fileio): Implement this.
803 * filelock.c (create_lock_file): If symbolic links don't work, so
804 we use a regular file as a lock file, do not fsync the lock file;
807 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
809 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.
810 (syms_of_minibuf): Adjust accodingly.
812 * callint.c (Fcall_interactively): Adjust calls accordingly.
814 2013-05-04 Eli Zaretskii <eliz@gnu.org>
816 * dispextern.h (WINDOW_WANTS_HEADER_LINE_P): Verify that
817 w->contents is a buffer before computing everything else.
818 Use parentheses to disambiguate last part of the condition.
820 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
821 assertion violations. (Bug#14062)
823 2013-05-01 David Reitter <david.reitter@gmail.com>
825 * nsfns.m (ns_tooltip): Initialize.
827 2013-04-28 Eli Zaretskii <eliz@gnu.org>
829 * coding.c (decode_coding_gap): Don't remove the character before
830 a newline unless it's a CR character. (Bug#14287)
832 2013-04-28 Dan Nicolaescu <dann@gnu.org>
834 * dispextern.h (struct face): Move enum face_underline_type
835 earlier so that bitfields can be in the same word.
837 2013-04-28 Jan Djärv <jan.h.d@swipnet.se>
839 * nsfns.m (handlePanelKeys): New function.
840 (EmacsOpenPanel:performKeyEquivalent:)
841 (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle
842 arrows/function/control and copy/paste keys (Bug#14296).
844 2013-04-27 Juri Linkov <juri@jurta.org>
846 * callint.c (Fcall_interactively): Call `Qread_number' for
847 interactive code letter `n' instead of using duplicate code.
850 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
852 * systime.h (make_timeval): Declare as 'const'.
854 2013-04-27 Kenichi Handa <handa@gnu.org>
856 * font.c (font_open_entity): Always open a font of manageable
859 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
861 Port better to AIX (Bug#14258).
862 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
865 2013-04-24 Kenichi Handa <handa@gnu.org>
867 * coding.c (decode_coding_iso_2022): When an invalid escape
868 sequence is encountered, reset the invocation and designation
869 status to the safest one.
871 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
873 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
874 Without this fix, "make distclean" leaves stamp-h1 behind.
876 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
878 * w32fns.c (w32_fullscreen_rect): New function to compute the
879 window rectangle for the given fullscreen mode.
880 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
881 longer tunes the window size. This keeps the window's edges flush
882 with the screen and allows the taskbar to hide itself in fullboth.
884 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
885 window decorations and uses the entire screen.
887 * w32term.h (w32_fullscreen_rect) Add prototype.
888 (struct w32_output): Replace normal_width, normal_height,
889 normal_top, and normal_left members with a single normal_placement
891 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):
893 (FRAME_NORMAL_PLACEMENT): New macro.
895 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
897 * minibuf.c (Ftest_completion): Silence compiler warning.
899 2013-04-15 Eli Zaretskii <eliz@gnu.org>
901 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
904 * frame.h (WINDOW_FRAME): Protect macro and its argument with
907 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
908 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
909 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
910 parentheses where appropriate.
912 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
914 * keyboard.c (timer_start_idle): Remove no-longer-used local.
916 2013-04-14 Eli Zaretskii <eliz@gnu.org>
918 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
919 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
920 Mention in the doc string that setting these variables takes
921 effect only after a call to set-window-buffer. (Bug#14200)
923 2013-04-13 Eli Zaretskii <eliz@gnu.org>
925 * indent.c (Fvertical_motion): Don't consider display strings on
926 overlay strings as display strings on the buffer position we
927 started from. This prevents vertical cursor motion from jumping
928 more than one line when there's an overlay string with a display
929 property at end of line.
930 Reported by Karl Chen <Karl.Chen@quarl.org> in
931 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.
933 2013-04-12 Stefan Monnier <monnier@iro.umontreal.ca>
935 * window.c (select_window): `record_buffer' even if window is
936 already selected (bug#14191).
938 2013-04-11 Eli Zaretskii <eliz@gnu.org>
940 * window.c (Fwindow_end): Test more flags, including the buffer's
941 last_overlay_modified flag, to determine whether the window's
942 display is really up-to-date. Prevents the function from
943 returning a stale value. (Bug#14170)
944 (Fwindow_line_height): Fix the test for up-to-date-ness of the
947 2013-04-10 Eli Zaretskii <eliz@gnu.org>
949 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
950 garbaged only if it is not already the top frame on its TTY.
951 This prevents flickering due to constant redrawing of TTY frames when
952 there are GUI frames open in the same session. (Bug#13864)
954 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
956 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
957 of marking the idle timers directly.
959 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
961 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
964 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>
966 * window.c (select_window): Don't record_buffer while the invariant is
967 temporarily broken (bug#14161).
969 * fns.c (Fdelq): Don't assume !NILP => CONSP.
971 2013-04-07 Eli Zaretskii <eliz@gnu.org>
973 * fileio.c (ACL_NOT_WELL_SUPPORTED): Define macro for WINDOWSNT.
975 2013-04-07 Romain Francoise <romain@orebokech.com>
977 Ignore additional platform-specific ACL errors (Bug#13702).
978 * fileio.c (ACL_NOT_WELL_SUPPORTED): New macro copied from gnulib.
979 (Fcopy_file, Fset_file_acl) [HAVE_POSIX_ACL]: Use it.
981 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
983 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
986 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
988 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
989 This bug was introduced by my 2013-02-25 change that simplified
990 data_start configuration. Without this change, on GNU/Linux
991 an Emacs configured with --enable-profiling fails immediately
992 due to a profiler signal.

1203 (expose_window_tree): Likewise.
1204 Use contents slot, not buffer, where appropriate.
1205 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1206 to avoid deleted windows. Use contents slot instead of buffer.

1606 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1608 * xdisp.c (init_iterator): Simplify because both character and byte
1609 positions are either specified or -1. Add eassert. Adjust comment.
1610 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both

1631 Include <sys/param.h> unconditionally, as that works elsewhere and
1632 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1633 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

1721 from Elisp via unread-command-events.
1723 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1724 functions to mean "no change".
1726 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

1886 (LINKS_MIGHT_NOT_WORK): New constant.
1887 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1888 (defined_WINDOWSNT): Remove.
1889 (MAKE_LOCK_NAME, file_in_lock_file_name):
1890 Always use .#FILE (not .#-FILE) for the file lock,
1891 even if it is a regular file.
1892 (rename_lock_file): New function.
1893 (create_lock_file): Use it.
1894 (create_lock_file, read_lock_data):
1895 Prefer a symbolic link for the lock file, falling back on a
1896 regular file if symlinks don't work. Do not try to create
1897 symlinks on MS-Windows, due to security hassles. Stick with
1898 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1899 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1900 host may be using a Windowsish file system, and cannot use
1901 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1902 doesn't work. Don't fail merely because of a symlink-contents
1903 length limit in the current file system; fall back on regular
1904 files. Increase the symlink contents length limit to 8 KiB, this
1905 should be big enough for any real use and doesn't crunch the
1907 (create_lock_file, lock_file_1, read_lock_data):
1908 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1909 (lock_file_1): Return error number, not bool. All callers changed.
1910 (ELOOP): New macro, if not already defined.
1911 (read_lock_data): Return size of lock file contents, not Lisp object.
1912 All callers changed. Handle a race condition if some other process
1913 replaces a regular-file lock with a symlink lock or vice versa,
1914 while we're trying to read the lock.
1915 (current_lock_owner): Parse contents more carefully, to help avoid
1916 confusing a regular-file lock with some other application's use
1917 of the file. Check for lock file contents being too long, or
1918 not parsing correctly.
1919 (current_lock_owner, lock_file):
1920 Allow foreign pid and boot times that exceed the local range.
1921 (current_lock_owner, lock_if_free, lock_file):
1922 Simplify allocation of lock file contents.
1923 * w32.c (sys_rename_replace): New function, containing most of
1924 the contents of the old sys_rename.
1925 (sys_rename): Use it.
1926 (fchmod): New dummy function.
1927 * w32.h (sys_rename_replace, fchmod): New decls.
1929 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1931 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1932 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1933 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1934 <dmantipov@yandex.ru>.
1936 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1938 * composite.c (get_composition_id, fill_gstring_header):
1939 Use make_uninit_vector where appropriate.
1940 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1941 * xselect.c (clean_local_selection_data): Likewise.
1943 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1945 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1946 * image.c (imagemagick_load_image): Calculate height and width
1947 after flattening the image, not before.
1949 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1951 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1952 * ftfont.c (ftfont_shape_by_flt): Likewise.
1953 * w32uniscribe.c (uniscribe_shape): Likewise.
1955 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1957 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1958 The old approach, which fell back on DIR/.#FILE.0 through
1959 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1960 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1961 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1962 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1963 because the locking mechanism was never reliable in that case).
1964 This patch fixes this and other bugs discovered by a code
1965 inspection that was prompted by
1966 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1967 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1968 to avoid interoperability problems between the MS-Windows and
1969 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1970 instances of Emacs now ignore each others' locks.
1971 * filelock.c (defined_WINDOWSNT): New constant.
1972 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1973 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1974 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1975 regular files on MS-Windows hosts.
1976 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1977 Use SAFE_ALLOCA to avoid problems with long file names.
1978 (MAX_LFINFO): Now a local constant, not a global macro.
1979 (IS_LOCK_FILE): Remove.
1980 (lock_file_1): Don't inspect errno if symlink call succeeds;
1981 that's not portable.
1982 (lock_file): Document that this function can return if lock
1984 (lock_file): Don't access freed storage.
1986 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1988 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1990 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1992 * textprop.c: Use bool for booleans.
1993 (validate_interval_range, Fadd_text_properties)
1994 (Fremove_text_properties): Prefer bool to int when either works.
1996 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1998 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1999 If the interval tree changes as a side effect of calling
2000 modify_region, re-do processing starting from the call to
2001 validate_interval_range. (Bug#13743)
2003 2013-02-28 Eli Zaretskii <eliz@gnu.org>
2005 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
2008 2013-02-27 Eli Zaretskii <eliz@gnu.org>
2010 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
2011 _SH_DENYRW flag, instead of emacs_open, to deny any other process
2012 access to the lock file until it is written and closed.
2015 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
2017 * callint.c (Qcall_interactively):
2018 * macros.c (Qexecute_kbd_macro):
2021 2013-02-26 Bastien Guerry <bzg@gnu.org>
2023 * window.c (Frecenter): Tiny docstring enhancement.
2025 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
2027 Minor textprop integer cleanup.
2028 * intervals.h, textprop.c (add_text_properties_from_list):
2029 Return void, not int, since nobody uses the return value.
2030 * textprop.c (validate_plist, add_properties, remove_properties)
2031 (Fadd_text_properties):
2032 Don't assume list length fits in int.
2033 (interval_has_all_properties, interval_has_some_properties)
2034 (interval_has_some_properties_list, add_properties, remove_properties)
2035 (Fadd_text_properties, Fremove_text_properties)
2036 (Fremove_list_of_text_properties, text_property_stickiness):
2037 Use bool for booleans.
2038 (Fadd_text_properties, Fremove_text_properties):
2039 (Fremove_list_of_text_properties):
2040 Reindent do-while as per GNU style.

2044 Implement CLASH_DETECTION for MS-Windows.
2046 * filelock.c [WINDOWSNT]: Include w32.h.
2047 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
2048 function of that name. Up-case the macro arguments.
2049 (IS_LOCK_FILE): New macro.
2050 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
2051 (create_lock_file): New function, with body extracted from
2053 [WINDOWSNT]: Implement lock files by writing a regular file with
2054 the lock information as its contents.
2055 (read_lock_data): New function, on Posix platforms just calls
2057 [WINDOWSNT]: Read the lock info from the file.
2058 (current_lock_owner): Call read_lock_data instead of calling
2059 emacs_readlinkat directly.
2060 (lock_file) [WINDOWSNT]: Run the file name through
2063 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
2064 just check if the process by that PID exists.
2066 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
2067 also present, as doing so will fail to error out if the file
2070 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
2072 * textprop.c (Fadd_text_properties, Fremove_text_properties)
2073 (Fremove_list_of_text_properties): Skip all of the intervals in
2074 the region between START and END that already have resp. don't
2075 have the requested properties, not just the first one.
2076 Add assertions that the loop afterwards always modifies the
2077 properties. (Bug#13743)
2079 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
2081 * callint.c (Fcall_interactively): Use the right lexical environment

2087 Simplify data_start configuration (Bug#13783).
2088 This is a followon simplification to the fix for Bug#13650.
2089 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
2090 (START_FILES): Remove. All uses removed.
2091 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
2092 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
2093 (buildobj.h): Use it.
2094 ($(ALLOBJS)): Depend on globals.h.
2095 (temacs$(EXEEXT)): Use $(ALLOBJS).
2096 * autodeps.mk (ALLOBJS): Move to Makefile.in.
2097 * deps.mk (vm-limit.o):
2098 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
2099 Do not depend on mem-limits.h.

2106 (make_hdr): Use DATA_START instead of start_of_data.
2107 * vm-limit.c: Move most of mem-limits.h's contents here.
2108 (data_start): New decl. It's OK if this is approximate,
2109 so simplify-away some unnecessary exactness.
2110 (POINTER): Remove; all uses removed.
2111 (data_space_start): Now char *, to avoid casts.
2112 (exceeds_lisp_ptr): New function, replacing the old
2113 EXCEEDS_LISP_PTR macro. All uses changed.
2114 (check_memory_limits): Simplify and remove casts.
2115 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

2128 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
2129 and diagnosed by Andreas Schwab in
2130 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
2132 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
2134 Assume C89 or better.
2135 * ralloc.c (SIZE, POINTER, NIL):
2136 * vm-limit.c (POINTER):
2137 Remove, replacing all uses with C89 equivalents. These old
2138 symbols were present only for porting to pre-C89 platforms.
2140 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
2142 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

2158 2013-02-19 Daniel Colascione <dancol@dancol.org>
2160 * sheap.c (report_sheap_usage): Use message, not message1, so
2161 that we don't try to create a buffer while we're in the middle
2162 of dumping Emacs. Explain why.
2164 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
2166 * search.c (find_newline): Return byte position in bytepos.

2179 2013-02-19 Eli Zaretskii <eliz@gnu.org>
2181 * w32proc.c (new_child): Avoid leaking handles if the subprocess
2182 resources were not orderly released.
2184 2013-02-17 Eli Zaretskii <eliz@gnu.org>
2186 * xdisp.c (x_draw_vertical_border): For a window that is neither

2210 * w32.c (sys_chown): Remove unused function.
2212 * w32term.c <input_signal_count>: Declare 'volatile'
2213 unconditionally. (Bug#9066)
2215 * w32.c (set_errno): Reset h_errno and don't set it to any other
2216 value. Set errno instead.
2217 (check_errno): Reset h_errno.
2218 (sys_socket, socket_to_fd, sys_bind, sys_connect)

2241 make sure errno is set to an appropriate value. (Bug#13546)
2242 (socket_to_fd): Add assertion against indexing fd_info[] with a
2243 value that is out of bounds.
2244 (sys_accept): If fd is negative, do not set up the child_process
2245 structure for reading.
2247 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
2249 * composite.c (fill_gstring_header): Remove useless prototype.

2261 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2263 Fix AIX port (Bug#13650).
2264 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2265 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2266 was #undeffed earlier, so it cannot be used as a macro here.
2267 Use the constant and not the macro.
2269 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2271 * w32proc.c (new_child): If no vacant slots are found in
2272 child_procs[], make another pass looking for slots whose process
2273 has exited or died. (Bug#13546)
2275 * w32.c (sys_pipe): When failing due to file descriptors above
2276 MAXDESC, set errno to EMFILE.
2277 (_sys_read_ahead): Update cp->status when failing to read serial
2278 communications input, so that the status doesn't stay at
2279 STATUS_READ_IN_PROGRESS. (Bug#13546)
2281 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
2283 * gtkutil.c (tb_size_cb): New function.
2284 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
2286 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>

2293 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
2295 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

2303 2013-02-13 Glenn Morris <rgm@gnu.org>
2305 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
2307 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2309 Improve AIX port some more (Bug#13650).
2310 With this, it should be as good as it was in 23.3, though it's
2311 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2312 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2313 * unexaix.c (start_of_text): Remove.
2314 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2315 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2316 (orig_load_scnptr, orig_data_scnptr):
2317 Now off_t, not long, since they are file offsets.
2318 (make_hdr): Use _data, not start_of_data ().
2319 This is the key part of the fix.
2320 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2321 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2323 * pre-crt0.c (data_start): Initialize to 1.
2324 This ports to compilers that optimize the external declaration
2325 'int x = 0;' as if it were 'int x;' to shrink the executable.
2327 Improve AIX port (Bug#13650).
2328 This doesn't fix the bug, but it makes progress: Emacs builds now.
2329 * unexaix.c: Include inttypes.h, stdarg.h.
2330 (report_error, report_error_1): Mark as _Noreturn.
2331 (report_error): Don't report the wrong errno.
2332 (report_error_1): Now varargs. All callers changed.
2333 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2334 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2335 (write_ptr): Use %p to print address rather than %lx and a cast
2336 to unsigned long. Grow buffer a bit, to be safer.
2338 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2340 * bidi.c (bidi_resolve_neutral): After finding the next
2341 non-neutral character, accept NEUTRAL_ON type as well, because
2342 directional control characters, such as LRE and RLE, have their
2343 type converted to that by bidi_resolve_weak. This avoids aborts
2344 when LRE/RLE follows a run of neutrals.
2345 (bidi_move_to_visually_next): Assert that return value of
2346 bidi_peek_at_next_level is non-negative. Negative values will
2349 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>

2361 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2362 Update dependencies.
2364 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2366 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2368 (display_line): Set w->region_showing to the value of
2369 it->region_beg_charpos, not to -1. This fixes redisplay
2370 optimization when cursor is moved up after M->. (Bug#13623)
2372 (try_scrolling): Scroll text up more if point is too close to ZV
2373 and inside the scroll margin. This makes sure point is moved
2374 outside the scroll margin in these cases.
2376 * window.h (struct window): region_showing can no longer be
2379 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2381 Tune by using memchr and memrchr.
2382 * doc.c (Fsnarf_documentation):
2383 * fileio.c (Fsubstitute_in_file_name):
2384 * search.c (find_newline, scan_newline):
2385 * xdisp.c (pos_visible_p, display_count_lines):
2386 Use memchr and memrchr rather than scanning byte-by-byte.
2387 * search.c (find_newline): Rename from scan_buffer.
2388 Omit first arg TARGET, as it's always '\n'. All callers changed.
2390 Clean up read_key_sequence a tiny bit more.
2391 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2392 (read_key_sequence): Remove unused locals.
2394 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2396 Clean up read_key_sequence a bit; reread active keymaps after first event.
2397 * keyboard.c (read_char, read_char_x_menu_prompt)
2398 (read_char_minibuf_menu_prompt):
2399 Replace nmaps+maps with a single `map' arg.
2400 (follow_key): Operate on a single map.
2401 (active_maps): New function.
2402 (test_undefined): Also return true for nil bindings.
2403 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2404 a single (composed) keymap. Remember `first_event' to choose the right
2405 set of active keymaps. Recompute the set of keymaps after receiving
2406 the first event. Remove GOBBLE_FIRST_EVENT.
2407 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2408 * keyboard.h (read_char): Update declaration.
2409 * lread.c (read_filtered_event): Adjust call to read_char.
2411 2013-02-11 Eli Zaretskii <eliz@gnu.org>
2413 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2414 Don't use the limitation on backwards movement when lines are truncated
2415 in the window. (Bug#13675)
2417 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2419 * marker.c (set_marker_internal): If desired position is passed
2420 as a marker, avoid call to buf_charpos_to_bytepos.
2421 * window.c (Fset_window_point): Omit redundant type checking.
2422 (Fset_window_start): Likewise. Format comment.
2423 (window_scroll_pixel_based): Use set_marker_restricted_both
2424 with character and byte positions obtained from an iterator.
2425 (Fset_window_configuration): Use set_marker_restricted_both.
2426 * xdisp.c (message_dolog): Likewise.
2428 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2430 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2431 When text lines are longer than window's screen lines, don't move back
2432 too far. This speeds up some redisplay operations. (Bug#13675)
2434 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2436 * syntax.c (scan_sexps_forward): Fix byte position calculation
2437 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
2439 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
2441 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
2442 that was not needed.
2444 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2446 Minor hashing refactoring.
2447 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2448 (sxhash_float): Return EMACS_UINT, for consistency with the other
2450 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2451 non-static inline function and therefore can't use static vars.
2452 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2453 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2454 with the other hash functions.
2456 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2458 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2459 XXXXXX part of the temporary file pattern is not downcased even
2460 when w32-downcase-file-names is non-nil. (Bug#13661)
2462 * xdisp.c (decode_mode_spec): Remove handling of %t.
2464 * msdos.c (careadlinkatcwd): Remove.
2466 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2468 * lread.c (skip_dyn_bytes): New function (bug#12598).
2469 (read1): Use it. Use getc instead of READCHAR to read bytes.

2484 * lisp.h (make_uninit_vector): New function.
2485 * alloc.c (Fvector, Fmake_byte_code):

2501 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
2503 * coding.c (Fdefine_coding_system_internal): Use AREF where
2504 argument is known to be a vector.
2505 * fns.c (Flocale_info): Likewise for ASET.
2506 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2507 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2509 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2511 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2514 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
2515 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
2516 updateCollectionBehaviour.
2518 * nsterm.m (NEW_STYLE_FS): Remove.
2519 (ns_last_use_native_fullscreen): New variable.
2520 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2521 (x_set_window_size): Do not take title bar and tool bar into account
2522 if isFullscreen returns YES.
2523 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2524 (check_native_fs): New function.
2525 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
2526 (ns_term_init): Remove NEW_STYLE_FS.
2527 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
2528 and tool bar if isFullscreen returns NO.
2529 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2530 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2531 with HAVE_NATIVE_FS.
2532 (window:willUseFullScreenPresentationOptions:): New method.
2533 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.

2541 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2542 (syms_of_nsterm): Add ns-use-native-fullscreen.
2544 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2546 * fileio.c (Qchoose_write_coding_system): Now static.
2548 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2550 * xdisp.c (window_buffer_changed): region_showing can be negative,
2551 which still means region is being displayed.
2552 (redisplay_internal): Resurrect code that forced redisplay of the
2553 whole window when showing region and the mark has changed.
2554 Record the new mark position to allow redisplay optimizations.
2555 (display_line): If it->region_beg_charpos is non-zero, set the
2556 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2558 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2559 not bitfield of 1 bit.
2561 2013-02-03 Daniel Colascione <dancol@dancol.org>
2563 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2564 daemon mode works on cygw32 when Emacs is installed and not just
2567 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2569 Avoid file time stamp bug on MS-Windows (Bug#13149).
2570 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2571 as FAT32 doesn't update time stamps when truncating them.
2572 Also, check that a file time stamp is not a multiple of 100 ns;
2573 this should catch all instances of the problem on MS-Windows,
2574 as its native file system resolution is 100 ns or worse, and
2575 checking for a non-multiple of 100 ns should impose only a small
2576 overhead on systems with ns resolution.
2578 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2580 Avoid encoding file names on MS-Windows when they need to be run
2581 through dostounix_filename.
2582 * w32.c (normalize_filename): Accept an additional argument
2583 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2584 downcase it even if w32-downcase-file-names is non-nil.
2585 (dostounix_filename): Accept an additional argument MULTIBYTE and
2586 pass it to normalize_filename.
2587 (emacs_root_dir): Adjust.
2589 * msdos.h (dostounix_filename): Adjust prototype.
2591 * w32.h (dostounix_filename): Adjust prototype.
2593 * msdos.c (dostounix_filename): Accept an additional argument and
2595 (init_environment): Adjust callers of dostounix_filename.
2597 * fileio.c (Ffile_name_directory, file_name_as_directory)
2598 (directory_file_name, Fexpand_file_name)
2599 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2601 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2603 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2604 variables, as egetenv is case-insensitive for DOS_NT.
2606 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2607 with an encoded file name.
2609 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2610 Adjust calls to dostounix_filename.
2612 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2614 * unexw32.c (unexec): Adjust call to dostounix_filename.
2616 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2618 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2621 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2624 * callproc.c (Fcall_process): Make sure program name in PATH and
2625 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2626 is passed to exec/spawnve, which fails unless the file-name
2629 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2630 even if w32-quote-process-args is nil.
2632 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2634 Fix timestamp bug when write-region appends nothing (Bug#13149).
2635 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2636 the file's time stamp doesn't change if Emacs happens to write nothing
2637 to the file, and on a buggy file system this could cause Emacs to
2638 incorrectly infer that the file system doesn't have the bug.
2639 Avoid this problem by inhibiting the inference in this case.
2641 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2643 * window.h (struct window): Convert base_line_number, base_line_pos
2644 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2645 Convert region_showing member from Lisp_Object to bitfield.
2646 Remove sequence_number member. Adjust comments.
2647 * window.c (sequence_number): Remove.
2648 (make_window): Initialize column_number_displayed.
2649 * print.c (print_object): Follow the printed representation of
2650 frames and print window pointer to distinguish between windows.
2651 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2652 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2653 (wset_column_number_displayed, wset_region_showing): Remove.
2654 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2655 (try_scrolling, try_cursor_movement, redisplay_window)
2656 (try_window_reusing_current_matrix, try_window_id, display_line)
2657 (display_mode_lines, decode_mode_spec): Adjust users.
2658 * .gdbinit (pwinx): Do not print sequence_number.
2660 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2662 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2663 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2664 * dired.c: Include <fcntl.h>.
2665 (open_directory): New function, which uses open and fdopendir
2666 rather than opendir. DOS_NT platforms still use opendir, though.

2668 (file_attributes): New function, with most of the old Ffile_attributes.
2669 (directory_files_internal, Ffile_attributes): Use it.
2670 (file_attributes, file_name_completion_stat): First arg is now fd,
2671 not dir name. All uses changed. Use fstatat rather than lstat +
2673 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2674 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2675 (emacs_readlinkat): New function, with much of the old
2676 Ffile_symlink_p, but with an fd argument for speed.
2677 It uses readlinkat rather than careadlinkatcwd, so that it
2678 need not assume the working directory.
2679 (Ffile_symlink_p): Use it.
2680 * filelock.c (current_lock_owner): Use emacs_readlinkat
2681 rather than emacs_readlink.
2682 * lisp.h (emacs_readlinkat): New decl.
2683 (READLINK_BUFSIZE, emacs_readlink): Remove.
2684 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2685 (emacs_norealloc_allocator, emacs_readlink): Remove.
2686 This stuff is moved to fileio.c.
2687 * w32.c (fstatat, readlinkat): New functions.
2688 (careadlinkat): Don't check that fd == AT_FDCWD.
2689 (careadlinkatcwd): Remove; no longer needed.
2691 2013-01-31 Glenn Morris <rgm@gnu.org>
2693 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2694 (Fwrite_region): Update for new choose_write_coding_system args.

2698 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2700 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2701 (sys_close): Zero out the flags for the file descriptor before
2702 closing it. (Bug#13546)
2704 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2705 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2706 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2709 * w32.c (w32_get_long_filename, init_environment, readlink):
2710 Support file names encoded in DBCS codepages.
2711 (readlink): Use the current file-name-coding-system, not the ANSI
2712 codepage, to decode and handle targets of symlinks.
2714 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2716 * w32.c (opendir): Now accepts a 'const char *'.
2718 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2720 Remove obsolete redisplay code. See the discussion at
2721 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2722 * dispnew.c (preemption_period, preemption_next_check): Remove.
2723 (Vredisplay_preemption_period): Likewise.
2724 (update_frame, update_single_window, update_window, update_frame_1):
2725 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2726 used, following the 2012-06-22 change.
2728 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2730 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2732 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2734 * font.c (num_fonts): Remove the leftover from old
2735 debugging code. Adjust comment style here and there.
2736 * insdel.c (insert_1): Remove.
2737 * lisp.h (insert_1): Remove prototype.
2738 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2740 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2742 * w32.c (max_filename_mbslen): New function.
2743 (normalize_filename, readdir): Use it to detect locales where ANSI
2744 encoding of file names uses a double-byte character set (DBCS).
2745 If a DBCS encoding is used, advance by characters using
2746 CharNextExA, instead of incrementing a 'char *' pointer.
2747 Use _mbslwr instead of _strlwr. (Bug#13515)
2749 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2750 request of memory reservation to 1.7GB. (Bug#13065)

2760 Avoid redundant calls to strlen.
2762 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2764 Drop async_visible and async_iconified fields of struct frame.
2765 This is possible because async input is gone; for details, see
2766 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2767 * frame.h (struct frame): Remove async_visible and async_iconified
2768 members, convert garbaged to unsigned bitfield. Adjust comments.
2769 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2770 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2771 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2772 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2773 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2775 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2776 properly. Likewise for obscured.
2778 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT

2786 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2788 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2790 * xdisp.c (message2, message2_nolog): Remove functions.
2791 (message3, message3_nolog): Extract nbytes and multibyteness directly
2792 from the string. Change all callers.
2793 (message3_nolog): Don't set message_enable_multibyte since set_message
2794 will reset it anyway.
2795 (message1, message1_nolog): Use message3.
2796 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2797 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2798 (set_message): Drop all but the second arg, which has to be a string.
2799 (set_message_1): Simplify now that we know that a1 is NULL and the
2800 second arg is a string.
2801 * frame.h (struct frame): Remove `message_buf' field.
2802 Use glyphs_initialized_p instead.
2803 (FRAME_MESSAGE_BUF): Remove macro.
2804 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2805 * lisp.h (message2, message2_nolog): Remove declarations.
2806 (message3, message3_nolog): Update declarations.
2807 * keyboard.c (read_char_minibuf_menu_text)
2808 (read_char_minibuf_menu_width): Remove vars.
2809 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2810 to correctly handle multibyte strings.
2811 * frame.c (delete_frame): Don't free message_buf any more.
2812 * editfns.c (message_text, message_length): Remove vars.
2813 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2814 * fileio.c (auto_save_error): Use message3 instead of message2.
2815 * dispnew.c (adjust_frame_message_buffer): Remove function.
2817 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2819 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2820 real estate used for the tool bar and the menu bar.
2822 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2824 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2825 hidden buffer is prepared to modification (Bug#13164).
2827 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2829 * window.h (struct window): Change window_end_valid member from
2830 Lisp_Object to a bitfield. Adjust comments.
2831 (wset_window_end_valid): Remove.
2832 * window.c (adjust_window_count): Clear window_end_valid.
2833 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2834 (Fwindow_line_height, set_window_buffer, Frecenter)
2835 (Fsplit_window_internal, Fdelete_other_windows_internal)
2836 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2837 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2838 * xdisp.c (check_window_end, reconsider_clip_changes)
2839 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2840 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2841 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2843 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2845 * xdisp.c (mark_window_display_accurate): Simplify the loop
2846 assuming that the only one of vchild, hchild or buffer window
2847 slots is non-nil. Call mark_window_display_accurate_1 for
2848 the leaf windows only.
2849 (mark_window_display_accurate_1): Always assume leaf window.
2852 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2854 * emacs.c (Qkill_emacs_hook): Now static.
2856 * fileio.c (Finsert_file_contents): Simplify.
2857 Remove unnecessary assignments and tests.
2859 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2861 * w32.c (acl_set_file): Don't test for errors unless
2862 set_file_security returns FALSE. Avoids spurious errors when
2865 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2867 * fileio.c (Finsert_file_contents): Revert code introduced at
2868 2013-01-18 in favor of the simpler and generally better fix.
2869 Save stack space by removing 'buffer' and reusing 'read_buf'
2872 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2874 * lisp.h (eabs): Define unconditionally (Bug#13419).
2875 The old "#if !defined (eabs)" was an unnecessary revenant of back
2876 when this macro was called "abs". Document 'eabs' better.
2878 2013-01-19 Glenn Morris <rgm@gnu.org>
2880 * fns.c (Frandom): Doc fix.
2882 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2884 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2885 segfault when there are lots of overlays.
2887 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2888 when there are lots of overlays.
2889 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2890 for the details and a way to reproduce.
2892 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2894 * fileio.c: Use O_APPEND to append.
2895 This corresponds better to the natural interpretation of "append",
2896 and avoids the need to open the output file twice, or to invoke
2897 lseek when APPEND is neither nil nor a number.
2898 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2899 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2900 file possibly twice, and lseeking to its end; this avoids the
2901 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2902 at the same time: the combination is never needed and apparently
2903 it doesn't work with DOS_NT.
2905 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2906 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2908 Allow floating-point file offsets.
2909 Problem reported by Vitalie Spinu in
2910 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2911 * fileio.c (emacs_lseek): Remove.
2912 (file_offset): New function.
2913 (Finsert_file_contents, Fwrite_region): Use it.
2915 2013-01-19 Chong Yidong <cyd@gnu.org>
2917 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2918 aborting on Fsignal (Bug#13289).
2920 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2922 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2923 set_file_security as failure due to insufficient privileges.
2924 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2925 (fstat): Return owner and group like 'stat' and 'lstat' do.
2927 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2929 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2930 The bug was observed on Ubuntu operating inside a virtual machine,
2931 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2932 The workaround introduces a race condition on non-buggy hosts,
2933 but it's an unlikely race and anyway there's a nearly identical
2934 nearby race that can't be fixed.
2935 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2937 (Fwrite_region): Test for file system time stamp bug.
2938 (init_fileio): New function.
2939 * lisp.h (init_fileio): Declare it.
2940 * emacs.c (main): Call it.
2942 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2943 and make it more consistent with other stat-failure diagnostics.
2945 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2947 Fix crash when inserting data from non-regular files.
2948 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2949 for the error description produced by valgrind.
2950 * fileio.c (read_non_regular): Rename to read_contents.
2951 Free Lisp_Save_Value object used to pass parameters.
2952 (read_non_regular_quit): Rename to read_contents_quit.
2953 (Finsert_file_contents): Redesign internal file reading loop to adjust
2954 gap and end positions after each read and so help make_gap to work
2955 properly. Do not signal an I/O error too early and so do not leave
2956 not yet decoded characters in a buffer, which was the reason of
2957 redisplay crash. Use list2 to build return value. Adjust comments.
2959 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2961 Close a race when statting and reading files (Bug#13149).
2962 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2963 This avoids a race if the file is renamed between stat and open.
2964 This race is not the problem originally noted in Bug#13149;
2965 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2967 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2974 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2975 * alloc.c (format_save_value): Rename to make_save_value.
2976 (make_save_pointer): New function.
2977 (record_xmalloc): Use make_save_pointer.
2978 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2979 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2980 Change users of make_save_value to make_save_pointer.
2981 Likewise for format_save_value and make_save_value.

2992 * alloc.c (free_save_value): Now static.
2994 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2996 * keymap.c (map_keymap_internal): Use format_save_value.
2997 (map_keymap_char_table_item): Adjust accordingly.
2998 * fileio.c (non_regular_fd, non_regular_inserted)
2999 (non_regular_nbytes): Remove.
3000 (Finsert_file_contents): Convert trytry to ptrdiff_t.
3001 Use format_save_value to pass parameters to read_non_regular.
3002 (read_non_regular): Use XSAVE_ macros to extract parameters.
3004 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
3006 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
3008 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
3010 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
3011 extraction from any Lisp_Save_Value slot. Add type checking.
3012 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
3013 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
3014 * xselect.c: All users changed.
3016 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
3018 Some convenient bits to deal with Lisp_Save_Values.

3024 object with the specified internal structure.
3025 (make_save_value): Reimplement using format_save_value.
3026 * editfns.c (save_excursion_save): Use format_save_value.
3027 (save_excursion_restore): Use XSAVE_OBJECT.
3029 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
3031 Avoid needless casts with XSAVE_POINTER.
3032 * alloc.c (mark_object) [GC_MARK_STACK]:
3033 * dired.c (directory_files_internal_unwind):
3034 * fileio.c (do_auto_save_unwind):
3035 * gtkutil.c (pop_down_dialog):
3036 * keymap.c (map_keymap_char_table_item):
3037 * lread.c (load_unwind):
3038 * nsmenu.m (pop_down_menu):
3039 * print.c (print_object) [GC_MARK_STACK]:
3040 * xfns.c (clean_up_file_dialog):
3041 * xmenu.c (cleanup_widget_value_tree):
3042 Omit casts between XSAVE_POINTER and a pointer type.
3044 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
3046 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
3047 * eval.c (eval_sub): Protect `form' from being GCed before its
3048 car and cdr becomes protected with the backtrace entry.
3050 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
3052 Make Lisp_Save_Value more versatile storage for up to four objects.
3053 * lisp.h (toplevel): Enumeration to describe types of saved objects.
3054 (struct Lisp_Save_Value): New layout. Adjust comments.
3055 (XSAVE_POINTER): New macro.
3056 (XSAVE_INTEGER): Likewise.
3057 (allocate_misc): Add prototype.
3058 (free_misc): Likewise.

3061 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
3062 (free_save_value): Likewise.
3063 (mark_object): Likewise.
3064 * editfns.c (save_excursion_save): Pack everything within
3065 Lisp_Save_Value and so avoid xmalloc.
3066 (save_excursion_restore): Adjust to match new layout. Use free_misc
3067 because we do not allocate extra memory any more. Add eassert.
3068 * print.c (print_object): New code to print Lisp_Save_Value. Do not
3069 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
3070 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
3071 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

3076 * nsfont.m (LCD_SMOOTHING_MARGIN): New define.
3077 (nsfont_draw): Remove disabling of LCD smoothing.
3078 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
3079 Bug#11484 with LCD smoothing on.
3081 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
3083 Fix SIGDANGER handlers, for AIX (Bug#13408).
3084 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
3085 Move handlers here from emacs.c; they were out of place.
3087 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
3089 * xterm.c (syms_of_xterm): Adjust documentation for
3090 scroll-bar-adjust-thumb-portion.
3092 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)

3095 determine whether scroll bar thumb size should be adjusted or not.
3096 Use variable for MOTIF.
3098 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for GTK.
3100 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

3104 (doCommandBySelector:): Set processingCompose to NO.
3106 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
3107 Remove check for fkeys count > zero, block/unblock fixes the real bug.
3108 (nsfont_list_family): Add block/unblock_input calls.
3109 (nsfont_open): Move block_input earlier. Add unblock_input before early
3111 (nsfont_draw): Add block/unblock_input calls.
3113 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
3115 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
3116 for old_charpos and old_bytepos.
3118 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
3120 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
3121 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
3122 Clear tzvalbuf_in_environ if this workaround is in effect.
3123 Problem and fix reported by Kazuhiro Ito.
3125 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
3127 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):

3134 string cross-reference(s).
3136 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
3138 Avoid unnecessary byte position calculation for the gap movement.
3139 Since all users of move_gap do CHAR_TO_BYTE for other purposes
3140 anyway, all of them should use move_gap_both instead.
3141 * lisp.h (move_gap): Remove prototype.
3142 * insdel.c (move_gap): Remove.
3143 (move_gap_both): Add eassert.
3144 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

3150 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
3152 * term.c (init_tty): Use them instead of rolling our own code.
3153 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
3154 switches from 'signal' to 'pthread_sigmask', which is safer in
3155 multithreaded applications.
3156 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
3157 which has already arranged for that.
3158 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
3159 This is the main part of the bug fix.
3161 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
3163 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around
3164 x_last_font_name (Bug#13403).
3166 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
3168 Omit buffer_slot_type_mismatch and use generic predicates to enforce
3169 the type of per-buffer values where appropriate.
3170 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
3171 predicate, which is how it's really used now. Adjust comment.
3172 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
3173 * buffer.c (buffer_slot_type_mismatch): Remove.
3174 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

3178 left-margin-width, right-margin-width, left-fringe-width,
3179 right-fringe-width, scroll-bar-width and buffer-display-count.
3180 Use Qstringp for default-directory, buffer-file-name,
3181 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
3182 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
3184 * data.c (store_symval_forwarding): Adjust to call the predicate.
3186 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
3188 * w32.c (get_name_and_id, acl_set_file):
3189 * w32term.c (w32fullscreen_hook): Remove unused local variables.
3191 2013-01-09 Dmitry Antipov <dmantipov@yandex.ru>
3193 * lisp.h (make_gap_1): New prototype.
3194 * buffer.h (GAP_BYTES_DFL, GAP_BYTES_MIN): New macros for the special
3196 * editfns.c (Fbuffer_size): Rename from Fbufsize to fit the common
3198 (syms_of_editfns): Adjust defsubr. Drop commented-out obsolete code.
3199 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
3200 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
3201 (make_gap_1): New function to adjust the gap of any buffer.
3202 * coding.c (coding_alloc_by_making_gap): Use it.
3203 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
3204 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
3206 2013-01-08 Juri Linkov <juri@jurta.org>
3208 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
3209 of (supports :underline (:style wave)). (Bug#13000)
3211 2013-01-08 Aaron S. Hawley <aaron.s.hawley@gmail.com>
3213 * undo.c (Fprimitive_undo): Move to simple.el.
3214 (syms_of_undo): Remove declarations for Sprimitive_undo.

3218 * keyboard.c (echo_add_key): Rename from echo_add_char.
3220 2013-01-06 Chong Yidong <cyd@gnu.org>
3222 * keyboard.c (echo_add_char): New function, factored out from
3223 echo_char. Don't add a space if the previous echo string was
3225 (echo_char): Use it.
3226 (read_key_sequence): When echoing mock input, ensure that the
3227 trailing dash is properly added.
3229 2013-01-05 Eli Zaretskii <eliz@gnu.org>
3231 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
3232 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
3233 digits for buffer positions, before misalignment starts.
3234 Display "0" for integer "object" field.
3235 (dump_glyph_row): Adapt the header line to changes in dump_glyph.

3240 * nsterm.m (ns_draw_underwave):
3241 * w32term.c (w32_draw_underwave):
3242 * xterm.c (x_draw_underwave): Make underwave look more triangular
3243 and also degrade gracefully for small fonts. (Bug#13000)
3245 * nsterm.m (ns_draw_text_decoration):
3246 * w32term.c (x_draw_glyph_string):
3247 * xterm.c (x_draw_glyph_string): Don't use previous underline
3248 thickness and position if previous underline type is underwave.
3250 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
3252 * fileio.c (Ffile_acl): Undocument return format.
3254 2013-01-02 Glenn Morris <rgm@gnu.org>
3256 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

3268 * term.c (tty_ins_del_lines):
3269 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
3270 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
3272 2012-12-31 Eli Zaretskii <eliz@gnu.org>
3274 * w32.c (unsetenv): Set up the string passed to _putenv
3276 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
3277 for the bug this caused.
3279 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
3281 * coding.c (Qmac): Now static.
3283 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
3285 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
3286 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
3287 handlebox_widget. Set toolbar_in_hbox to false/true, set
3288 toolbar_is_packed to true.
3289 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
3290 (update_frame_tool_bar): Check toolbar_is_packed for packing.
3291 Show all on TOOLBAR_TOP_WIDGET.
3292 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
3293 by TOOLBAR_TOP_WIDGET.
3294 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
3295 Check toolbar_is_packed.
3296 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
3297 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3298 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
3300 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3301 (xg_update_menubar): Update title only if
3302 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3303 (xg_update_submenu): Skip tearoff only if
3304 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3305 (xg_initialize): Initialize xg_detached_menus only if
3306 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3308 * xterm.h (struct x_output): Surround handlebox_widget with
3309 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
3310 toolbar_in_hbox is bool.
3312 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
3314 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
3315 (LIBS_GNUSTEP): Define.
3316 (LIBES): Add $(LIBS_GNUSTEP).
3317 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
3319 2012-12-30 Eli Zaretskii <eliz@gnu.org>
3321 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
3322 continuation glyph on a TTY with an indication of an empty line.
3325 2012-12-29 Eli Zaretskii <eliz@gnu.org>
3327 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
3328 file's SELinux context or ACLs successfully set, nil otherwise.
3330 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
3332 * w32proc.c (reader_thread): Avoid passing NULL handles to
3333 SetEvent and WaitForSingleObject.
3335 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
3337 Port EXTERNALLY_VISIBLE to Clang 3.2.
3338 * conf_post.h (__has_attribute): New macro.
3339 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
3341 2012-12-27 Glenn Morris <rgm@gnu.org>
3343 * cygw32.c (Fcygwin_convert_file_name_to_windows)
3344 (Fcygwin_convert_file_name_from_windows): Doc fixes.
3346 2012-12-27 Eli Zaretskii <eliz@gnu.org>
3348 * fileio.c (file_name_as_directory, directory_file_name):
3349 Accept an additional argument MULTIBYTE to indicate whether the input C
3350 came from a multibyte or a unibyte Lisp string; all callers
3351 adjusted. Don't assume the input string is always multibyte.
3353 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
3354 don't ENCODE_FILE them, and return a unibyte string if the input
3356 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
3357 don't assume the input strings will always be multibyte. If the
3358 input strings are multibyte, decode strings obtained from C
3361 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3363 * lisp.h (toplevel): Add two notices to the comment about
3364 defining a new Lisp data type.

3368 * alloc.c (valid_lisp_object_p): Adjust comment.
3370 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3372 * keyboard.c (record_asynch_buffer_change): Initialize an event
3373 only if it's really needed.
3374 * frame.h (enum output_method): Remove output_mac member since
3375 it's a leftover from the deleted code.
3376 * frame.c (Fframep): Adjust user here ...
3377 * terminal.c (Fterminal_live_p): ... and here.
3378 * coding.c (Qmac): Now here because it's only used to denote
3379 end-of-line encoding type.
3380 (syms_of_coding): DEFSYM it.
3381 * frame.h (Qmac): Remove duplicated declaration.
3383 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
3385 * window.c (select_window_1): Now static, since it's used only here.
3387 2012-12-25 Eli Zaretskii <eliz@gnu.org>
3389 * window.c (window_body_cols): Subtract display margins from the
3390 window body width on TTYs as well. See
3391 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
3392 for the original report.
3394 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
3396 * xdisp.c (redisplay_window): Remove inner local variable
3397 because the outer shadowed one has the same meaning.
3398 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3400 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3401 (xg_create_tool_bar): Adjust users.
3403 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3405 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3406 * buffer.c (Fget_buffer_create): Use it to set compact field of
3407 struct buffer_text to avoid accessing an uninitialized value
3408 when compact_buffer is called for the first time.
3409 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3410 (Fset_buffer_modified_p): Use buffer_window_count to check
3411 whether the buffer is displayed in some window.
3412 * xdisp.c (message_dolog): Likewise.
3414 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3416 * w32.c (acl_set_file): If setting the file security descriptor
3417 fails, and the new DACL is identical to the existing one, silently
3418 return success. This fixes problems for users backing up their
3419 own files without having the necessary privileges for setting
3420 security descriptors.
3422 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3424 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3425 after WaitForSingleObject returns normally. This expedites reader
3426 thread shutdown when delete_child triggers it.
3427 (reap_subprocess): More accurate commentary for why we call
3428 delete_child only when cp->fd is negative.
3430 * w32.c (sys_close): Do not call delete_child on a subprocess
3431 whose handle is not yet closed. Instead, set its file descriptor
3432 to a negative value, so that reap_subprocess will call
3433 delete_child on that subprocess when its SIGCHLD arrives.
3434 This avoids closing handles used for communications between sys_select
3435 and reader_thread, which doesn't give sys_select a chance to
3436 notice that the process exited and invoke the SIGCHLD handler for
3439 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3441 * nsfns.m (Fns_do_applescript): Run event loop until script has
3442 been executed (Bug#12969).
3443 (ns_run_ascript): Chech as_script for nil, set to nil after
3446 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3448 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3450 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3452 * w32term.c (w32fullscreen_hook): New function.
3453 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3455 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3457 * fileio.c (Finsert_file_contents): Doc fix.
3459 * w32proc.c (new_child, delete_child, find_child_pid): For a
3460 subprocess, consider its slot being in use as long as its process
3461 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3462 slot when a new process is started immediately after killing
3463 another one, without waiting enough time for the first process to
3464 be reaped and resources allocated for it be orderly freed.
3466 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3468 2012-12-21 Chong Yidong <cyd@gnu.org>
3470 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3472 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3474 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3476 * w32.c (get_name_and_id): Always pass NULL as the first argument
3477 of lookup_account_sid. Avoids crashes with UNC file names that
3478 refer to DFS domains, not to specific machine names. (Bug#12621)
3479 Remove now unused argument FNAME; all callers changed.
3480 (get_file_owner_and_group): Remove now unused argument FNAME; all
3483 2012-12-21 Chong Yidong <cyd@gnu.org>
3485 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3486 error for invalid chars, don't check for a nil return value.
3488 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3490 Avoid calls to CHAR_TO_BYTE if byte position is known.
3491 * editfns.c (make_buffer_string_both): Use move_gap_both.
3492 (Fbuffer_string): Use make_buffer_string_both.
3493 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3495 (buf_bytepos_to_charpos): Likewise.
3496 (charpos_to_bytepos): Remove.
3497 * fileio.c (Finsert_file_contents): Use move_gap_both.
3498 * search.c (Freplace_match): Likewise.
3499 * process.c (process_send_region): Likewise. Use convenient
3500 names for byte positions.
3501 * lisp.h (charpos_to_bytepos): Remove prototype.
3502 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3503 * insdel.c (move_gap): Likewise.
3505 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3507 * xdisp.c (redisplay_internal): Remove now-unused local.
3509 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3511 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3512 (redisplay_internal): Don't bother selecting the frame to get the
3513 proper value of frame-local variables (bug#13225).
3515 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3517 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3518 Rename 4th argument since it may be buffer or string. Adjust comment.
3519 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3521 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3523 * coding.c (Fdetect_coding_region): Do not check start and end with
3524 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3525 (code_convert_region): Likewise.
3527 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3529 * w32.c (acl_get_file, acl_set_file): Run the file name through
3530 map_w32_filename, and resolve any symlinks in the file name, like
3532 (acl_set_file): Call revert_to_self, if any privileges were
3535 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3537 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3538 ($(BLD)/w32.$(O)): Update dependencies.
3540 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3542 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3543 propagate redisplay's scrolling (if any) to the right window.
3544 (redisplay_internal): Use ensure_selected_frame.
3545 (display_mode_lines): Complete last fix.
3546 * window.c (select_window_1): New func, extracted from select_window.
3547 (select_window): Use it.
3548 * window.h (select_window_1): Declare.
3550 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3552 Emulate Posix ACL APIs on MS-Windows.
3553 * w32.c: Include sddl.h and sys/acl.h.
3554 (SDDL_REVISION_1): Define if not already defined.
3555 (g_b_init_get_security_descriptor_dacl)
3556 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3557 (g_b_init_is_valid_security_descriptor)
3558 (g_b_init_set_file_security): New static flags.

3570 (acl_free, acl_get_file, acl_set_file): New functions.
3572 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3574 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3576 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3577 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3578 for some of that bug's symptoms can now cause Emacs to abort.
3579 Remove the workaround.
3580 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3581 The bug that caused SIGCHLD to get lost has been fixed, and the
3582 workaround for it can now cause Emacs to abort.
3584 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3586 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3587 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3588 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3590 2012-12-16 Romain Francoise <romain@orebokech.com>
3592 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3593 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3594 and copy ACL entries of file in addition to SELinux context if set.
3595 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3597 * Makefile.in (LIBACL_LIBS): New macro.
3600 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3602 * fileio.c (internal_delete_file): Use bool for boolean.
3604 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3606 Fix bug #13079 on MS-Windows with temp files not being deleted.

3609 (register_child): First argument is now pid_t.
3610 (record_infile, record_pending_deletion): New prototypes.
3612 * w32proc.c (new_child): Initialize input_file and
3613 pending_deletion members of the child.
3614 (delete_child): Delete the child's temporary input file, if any,
3615 that is pending deletion.
3616 (register_child): First argument is now pid_t.
3617 (record_infile, record_pending_deletion): New functions.
3618 (reap_subprocess): Fix a typo in DebPrint string.
3619 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3621 * fileio.c (internal_delete_file): Return an int again: non-zero
3622 if delete-file succeeds, zero otherwise.
3624 * lisp.h (internal_delete_file): Adjust prototype.
3626 * callproc.c (Fcall_process): Don't overwrite infile with result
3628 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3629 asynchronous subprocess, record the name of the input file name,
3631 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3632 delete the file, record it as pending deletion when the subprocess
3635 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3637 * editfns.c [HAVE_PWD_H]: Include grp.h.
3639 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3641 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3643 Fix permissions bugs with setgid directories etc. (Bug#13125)
3644 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3645 to mark it as a placeholder. The old value was often wrong.
3646 The only user of this attribute has been changed to use
3647 file-ownership-preserved-p instead, with its new group arg.
3648 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3650 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
3652 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
3653 Keep selected_window and selected_frame in sync.
3655 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3657 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3658 try to get accurate owner and group information from NT file
3659 security APIs. This is to make most callers of 'stat' and
3660 'lstat', which don't need that information, much faster.
3662 * dired.c (Ffile_attributes) [WINDOWSNT]:
3663 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3664 owner and group information from 'lstat'.
3666 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3668 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3669 as that confuses set-auto-coding, so insist on the head-read
3670 returning the full 1024 bytes. Let lseek compute the tail offset;
3671 less work for us. Do not ignore I/O errors when reading the tail.
3673 * xdisp.c: Minor style fixes.
3674 (init_iterator): Hoist assignment out of if-expression.
3675 (markpos_of_region): Callers now test for sign, not for -1.
3677 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3679 Minor redisplay optimization when the region length is zero.
3680 * xdisp.c (markpos_of_region): New function.
3681 (init_iterator): Do not highlight the region of zero length.
3682 (redisplay_window): Check whether the region is of non-zero length.
3683 (try_cursor_movement): Allow if the region length is zero.
3684 (try_window_reusing_current_matrix, try_window_id): Likewise.
3686 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3688 * search.c (search_buffer): Check the inverse translations of each
3689 character in pattern when the buffer being searched is unibyte.
3692 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3694 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3695 files, fixing a regression from 24.2.
3696 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3698 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3700 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3701 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3702 Remove unnecessary S_ISLNK test, as (contra the comments) this
3703 function can't copy symlinks. Improve quality of error message
3704 when attempting to copy files that are neither regular files nor
3707 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
3709 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

3711 * window.c (Frecenter):

3937 * dbusbind.c (Fdbus_init_bus):
3939 * xterm.c (x_term_init):

3950 no longer needed here.
3951 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:

3953 (set_time_zone_rule): Maintain the TZ=value string separately.
3954 (syms_of_editfns): Don't initialize initial_tz;
3955 init_editfns now does it.
3956 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3957 * lisp.h (xputenv): New decl.
3959 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

3975 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3976 Remove USG and vlimit methods; no longer used these days.
3977 Add #error catchall just in case.
3979 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3980 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3981 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

4003 This will cause a production Emacs to dump core instead of
4006 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
4008 * frame.c (make_frame): Do not set window's buffer to t.
4009 * window.c (Fsplit_window_internal): Likewise. Previously it was
4010 used to indicate that the window is being set up. Now we use
4011 set_window_buffer for all new windows, so the condition in ...
4012 (Fset_window_buffer): ... is always true and can be removed.
4014 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
4016 Convenient macro to check whether the buffer is hidden.
4017 * buffer.h (BUFFER_HIDDEN_P): New macro.
4018 * frame.c (make_frame): Use it. Adjust comment.
4019 * buffer.c (candidate_buffer): New function.
4020 (Fother_buffer, other_buffer_safely): Use it.
4022 2012-12-06 Eli Zaretskii <eliz@gnu.org>
4024 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
4025 if the child process is still running. Instead, exit the wait
4026 loop and return zero. (Bug#13086)
4028 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
4030 * frame.h (x_char_width, x_char_height): Remove prototypes.

4041 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
4043 Fix a recently-introduced delete-process race condition.
4044 * callproc.c, process.h (record_kill_process):
4045 New function, containing part of the old call_process_kill.
4046 (call_process_kill): Use it.
4047 This does not change call_process_kill's behavior.
4048 * process.c (Fdelete_process): Use record_kill_process to fix a
4049 race condition that could cause Emacs to lose track of a child.
4051 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
4053 Avoid code duplication between prev_frame and next_frame.
4054 * frame.c (candidate_frame): New function. Add comment.
4055 (prev_frame, next_frame): Use it. Adjust comment.
4057 2012-12-06 Eli Zaretskii <eliz@gnu.org>
4059 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
4060 fails, signal an error instead of continuing with an empty
4062 Encode expanded temp file pattern before passing it to mkstemp or
4065 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
4066 Encode the file name before passing it to dostounix_filename, in
4067 case it will downcase it (under w32-downcase-file-names).
4070 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
4072 Minor call-process cleanups.
4073 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
4074 at the same time as other platforms, to simplify analysis.
4075 No need for fd0_volatile since we have synch_process_fd.
4076 Avoid needless emacs_close; arg is always negative.
4078 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
4080 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

4085 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
4086 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

4092 member. Adjust users. Convert term_initted, delete_in_insert_mode,
4093 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
4094 members to a bitfields.
4096 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
4098 Don't let call-process be a zombie factory (Bug#12980).
4099 Fixing this bug required some cleanup of the signal-handling code.
4100 As a side effect, this change also fixes a longstanding rare race
4101 condition whereby Emacs could mistakenly kill unrelated processes,
4102 and it fixes a bug where a second C-g does not kill a recalcitrant
4103 synchronous process in GNU/Linux and similar platforms.
4104 The patch should also fix the last vestiges of Bug#9488,
4105 a bug which has mostly been fixed on the trunk by other changes.
4106 * callproc.c, process.h (synch_process_alive, synch_process_death)
4107 (synch_process_termsig, sync_process_retcode):
4108 Remove. All uses removed, to simplify analysis and so that
4109 less consing is done inside critical sections.
4110 * callproc.c (call_process_exited): Remove. All uses replaced
4111 with !synch_process_pid.
4112 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
4113 These take the role of what used to be in unwind-protect arg.
4115 (block_child_signal, unblock_child_signal):
4116 New functions, to avoid races that could kill innocent-victim processes.
4117 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
4118 (call_process_kill): Record killed processes as deleted, so that
4119 zombies do not clutter up the system. Do this inside a critical
4120 section, to avoid a race that would allow the clutter.
4121 (call_process_cleanup): Fix code so that the second C-g works again
4122 on common platforms such as GNU/Linux.
4123 (Fcall_process): Create the child process in a critical section,
4124 to fix a race condition. If creating an asynchronous process,
4125 record it as deleted so that zombies do not clutter up the system.
4126 Do unwind-protect for WINDOWSNT too, as that's simpler in the
4127 light of these changes. Omit unnecessary call to emacs_close
4128 before failure, as the unwind-protect code does that.
4129 * callproc.c (call_process_cleanup):
4130 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
4131 * process.c (record_deleted_pid): New function, containing
4132 code refactored out of Fdelete_process.
4133 (Fdelete_process): Use it.
4134 (process_status_retrieved): Remove. All callers changed to use
4135 child_status_change.
4136 (record_child_status_change): Remove, folding its contents into ...
4137 (handle_child_signal): ... this signal handler. Now, this
4138 function is purely a handler for SIGCHLD, and is not called after
4139 a synchronous waitpid returns; the synchronous code is moved to
4140 wait_for_termination. There is no need to worry about reaping
4141 more than one child now.
4142 * sysdep.c (get_child_status, child_status_changed): New functions.
4143 (wait_for_termination): Now takes int * status and bool
4144 interruptible arguments, too. Do not record child status change;
4145 that's now the caller's responsibility. All callers changed.
4146 Reimplement in terms of get_child_status.
4147 (wait_for_termination_1, interruptible_wait_for_termination):
4148 Remove. All callers changed to use wait_for_termination.
4149 * syswait.h: Include <stdbool.h>, for bool.
4150 (record_child_status_change, interruptible_wait_for_termination):
4152 (record_deleted_pid, child_status_changed): New decls.
4153 (wait_for_termination): Adjust to API changes noted above.
4155 * bytecode.c, lisp.h (Qbytecode): Remove.
4156 No longer needed after 2012-11-20 interactive-p changes.
4158 2012-12-03 Eli Zaretskii <eliz@gnu.org>
4160 * xdisp.c (redisplay_window): If the cursor is visible, but inside
4161 the scroll margin, move point outside the margin. (Bug#13055)
4163 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
4165 * gtkutil.c (my_log_handler): New function.
4166 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
4168 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4170 * lisp.h (modify_region): Rename to...
4171 (modify_region_1): ...new prototype.
4172 * textprop.c (modify_region): Now static. Adjust users.
4173 * insdel.c (modify_region): Rename to...
4174 (modify_region_1): ...new function to work with current buffer.
4175 Adjust comment and users. Use true and false for booleans.

4182 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
4184 (save_excursion_restore): Adjust to match saved data structure.
4185 Use free_save_value to offload some work from GC. Drop obsolete
4188 2012-12-03 Chong Yidong <cyd@gnu.org>

4192 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
4194 * w32fns.c: Remove prototype of atof.

4202 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4203 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already

4212 Fix xpalloc confusion after memory is exhausted.
4213 * alloc.c (xpalloc): Comment fix.
4214 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
4215 and signals an error, do not clear charset_table_size, as
4216 charset_table is still valid.
4217 * doprnt.c (evxprintf): Clear *BUF after freeing it.
4219 Use execve to avoid need to munge environ (Bug#13054).
4220 * callproc.c (Fcall_process):
4221 * process.c (create_process):
4222 Don't save and restore environ; no longer needed.
4223 * callproc.c (child_setup):
4224 Use execve, not execvp, to preserve environ.
4226 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
4228 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
4230 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4232 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
4233 display for sliced images (Bug#10500).
4235 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.

4240 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
4242 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
4244 * xdisp.c (window_outdated): Remove eassert since it hits
4245 some suspicious corner cases (see Bug#13007 and Bug#13012).
4246 (mode_line_update_needed): New function.
4247 (redisplay_internal, redisplay_window): Use it.
4248 (ensure_selected_frame): New function.
4249 (redisplay_internal, unwind_redisplay): Use it.
4250 (redisplay_internal): Move comment about buffer_shared...
4251 (buffer_shared_and_changed): ...near to its real use.
4253 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
4255 * callproc.c (Fcall_process): Don't misreport vfork failure.
4257 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
4259 * callproc.c (Fcall_process): Fix vfork portability problems.
4260 Do not assume that fd[0], count, filefd, and save_environ survive
4261 vfork. Fix bug whereby wrong errno value could be reported for
4262 pipe failure. Some minor cleanups, too, as follows. Move buf and
4263 bufsize to the context where they're needed. Change new_argv to
4264 be of type char **, as this is more convenient and avoids casts.
4265 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4266 Now local constants, not macros.
4268 2012-11-18 Kenichi Handa <handa@gnu.org>
4270 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
4271 for the variable "f".
4273 2012-11-13 Kenichi Handa <handa@gnu.org>
4275 * font.c (font_unparse_xlfd): Exclude special characters from the
4276 generating XLFD name.
4278 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

4281 * dired.c (stat_uname, stat_gname):
4282 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
4284 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

4303 violations when repeatedly clicking on the "Top" link of the
4304 "bread-crumbs" in Info buffers.

4314 were always defined.
4316 2012-11-24 Eli Zaretskii <eliz@gnu.org>
4318 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4319 between bpos_covered and bpos_max. This fixes cursor display when
4320 several display strings follow each other.
4322 * .gdbinit (pgx): If the glyph's object is a string, display the
4323 pointer to string data, rather than the value of the string object
4324 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4326 * indent.c (Fvertical_motion): If the starting position is covered
4327 by a display string, return to one position before that, to avoid
4328 overshooting it inside move_it_to. (Bug#12930)
4330 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
4332 * frame.h (struct frame): Remove display_preempted member

4335 * w32menu.c (pending_menu_activation): Remove since not
4337 (set_frame_menubar): Adjust user.
4338 * w32term.h (struct x_output): Drop outdated #if 0 code.
4339 (struct w32_output): Use bitfields for explicit_parent,
4340 asked_for_visible and menubar_active members.
4341 Drop unused pending_menu_activation member.
4342 * xterm.h (struct x_output): Drop outdated #if 0 code.
4343 Use bitfields for explicit_parent, asked_for_visible,
4344 has_been_visible and net_wm_state_hidden_seen members.
4346 2012-11-23 Eli Zaretskii <eliz@gnu.org>
4348 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
4349 of a literal "/". (Bug#12955)
4350 (gl-stamp): Invoke fc.exe directly, not through cmd.
4352 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
4354 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
4355 * dired.c: Assume HAVE_DIRENT_H.
4356 (NAMLEN): Remove, replacing with ...
4357 (dirent_namelen): New function. All uses changed. Use the GNU macro
4358 _D_EXACT_NAMELEN if available, as it's faster than strlen.
4359 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
4360 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
4361 * makefile.w32-in (DIR_H): Remove. All uses replaced with
4363 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
4364 * ndir.h: Rename to ../nt/inc/dirent.h.
4365 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
4366 Do not include <dirent.h>; no longer needed.
4367 * w32.c: Include <dirent.h> rather than "ndir.h".
4369 2012-11-23 Chong Yidong <cyd@gnu.org>
4371 * xftfont.c (xftfont_open): Remove duplicate assignment.
4373 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4375 * alloc.c (Fgarbage_collect): Unblock input after clearing
4376 gc_in_progress to avoid note_mouse_highlight glitch with GC.
4377 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4378 * msdos.c (IT_frame_up_to_date): Use it here...
4379 * w32term.c (w32_frame_up_to_date): ...here...
4380 * xterm.c (XTframe_up_to_date): ...and here...
4381 * nsterm.m (ns_frame_up_to_date): ...but not here.
4382 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
4384 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
4385 Do not check whether GC is in progress.
4387 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4389 * xdisp.c (window_buffer_changed): New function.
4390 (update_menu_bar, update_tool_bar): Use it to
4391 simplify large 'if' statements.
4392 (redisplay_internal): Generalize commonly used
4393 'tail' and 'frame' local variables.
4395 2012-11-22 Eli Zaretskii <eliz@gnu.org>
4397 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
4398 with Windows system header.
4400 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
4402 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
4403 * alloc.c: Assume unistd.h exists.
4404 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
4405 * sysdep.c (get_current_dir_name): Assume getcwd exists.
4406 (getwd) [USG]: Remove; no longer needed.
4407 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
4408 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
4409 * w32.h (getcwd): Remove decl.
4411 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
4413 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
4414 Make it set selected_window as well.

4419 * emacs.c (main): Set the G_SLICE environment variable for all
4420 Cygwin builds, not just GTK builds. See
4421 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
4423 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4425 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4426 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4427 Define for the MSVC compiler.
4429 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
4431 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4432 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
4433 dostounix_filename. Prevents crashes down the road, because
4434 dostounix_filename assumes it gets a unibyte string.
4435 Reported by Michel de Ruiter <michel@sentient.nl>, see

4455 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
4457 * xdisp.c (buffer_shared): Adjust comment.
4458 (buffer_shared_and_changed): New function.
4459 (prepare_menu_bars, redisplay_internal): Use it to
4460 decide whether all windows or frames should be updated.
4461 (window_outdated): New function.
4462 (text_outside_line_unchanged_p, redisplay_window): Use it.
4463 (redisplay_internal): Likewise. Fix indentation.
4465 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4467 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
4468 (syms_of_eval): Remove corresponding defsubr.
4469 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
4471 2012-11-19 Daniel Colascione <dancol@dancol.org>
4473 * w32fns.c (Fx_file_dialog):
4474 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4475 cygwin_convert_file_name*.
4477 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
4478 Rename cygwin_convert_path* to cygwin_convert_file_name*.
4480 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
4482 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
4484 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4486 * w32select.c: Include w32common.h before w32term.h, so that
4487 windows.h gets included before w32term.h uses some of its
4488 features, see below.
4490 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4492 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
4494 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
4496 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4498 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4499 (ns_select): Return at once if events are held (Bug#12834).
4501 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4503 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4504 Needed following 2012-10-20 change. (Bug#12902)
4506 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4508 * w32proc.c (waitpid): Remove unused label get_result.
4510 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4512 * makefile.w32-in (SYSWAIT_H): New macro.
4513 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4514 ($(BLD)/sysdep.$(O)): Update dependencies.
4516 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4518 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4519 * callproc.c (relocate_fd): Assume F_DUPFD.
4520 * emacs.c, term.c (O_RDWR): Remove.
4521 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4522 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4523 * nsterm.m: Assume <fcntl.h> exists.
4524 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4525 (create_pty, Fmake_network_process, server_accept_connection)
4526 (wait_reading_process_output, init_process_emacs):
4528 (wait_reading_process_output): Put in a special case for WINDOWSNT
4529 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4530 It's not clear this is needed, but it's a more-conservative change.
4531 (create_process): Assume FD_CLOEXEC.
4532 (create_process, create_pty): Assume O_NOCTTY.
4533 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4534 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4535 Omit if not DOS_NT, since F_GETFL is not defined there.
4536 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4537 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4539 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4540 lack it, since gnulib guarantees this.
4541 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4543 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4545 * w32.c (faccessat): Pretend that directories have the execute bit
4546 set. Emacs expects that, e.g., in files.el:cd-absolute.
4548 * w32proc.c (create_child): Don't clip the PID of the child
4549 process to fit into an Emacs integer, as this is no longer a
4551 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4552 reaping only the process specified by PID argument, if that is
4553 positive. Use PID instead of dead_child to know which process to
4554 reap. Wait for the child to die only if WNOHANG is not in
4556 (sys_select): Don't set dead_child.
4558 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4559 as it is no longer needed.
4561 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4563 (record_child_status_change): Remove the setting of
4564 record_at_most_one_child for the !WNOHANG case.
4566 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4568 Fix problems in ns port found by static checking.
4569 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4570 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4571 not to process group.
4572 (ns_select): Use emacs_write, not write, as that's more robust
4573 in the presence of signals.
4574 (fd_handler:): Check for read errors.
4576 2012-11-16 Glenn Morris <rgm@gnu.org>
4578 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

4582 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4584 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4586 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4587 use the same value of thread handle.
4588 (start_timer_thread): If the timer thread exited (due to error),
4589 clean up by closing the two handles it used. Duplicate the caller
4590 thread's handle here, so it gets duplicated only once, when
4591 launching the timer thread. Set priority of the timer thread, not
4593 (getitimer): Don't duplicate the caller thread's handle here.
4596 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4598 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4601 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4603 Remove no-longer-used pty_max_bytes variable.
4604 * process.c (pty_max_bytes): Remove; unused.
4605 (send_process): Do not set it.
4607 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4609 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4610 Update dependencies.
4612 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4614 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4615 This follows up on the 2012-09-29 patch that removed indirection
4616 for the 'function' field. Reported by Sergey Vinokurov in
4617 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4619 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4621 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4622 different name, as the MS runtime does not have such a function,
4623 and probably never will.) All callers changed. Ignore DIRFD
4624 value if PATH is an absolute file name, to match Posix spec
4625 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4628 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4630 * xdisp.c (echo_area_display, redisplay_internal):
4631 Omit redundant check whether frame_garbaged is set.
4633 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4635 Use faccessat, not access, when checking file permissions (Bug#12632).
4636 This fixes a bug that has been present in Emacs since its creation.
4637 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4638 which must set some sort of record. (Torek's bug report was against
4639 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4640 same common flaw.) See Torek's Usenet posting
4641 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4642 Posted: Fri Apr 8 14:18:56 1983.
4643 * Makefile.in (LIB_EACCESS): New macro.
4645 * callproc.c (init_callproc):
4646 * charset.c (init_charset):
4647 * fileio.c (check_existing, check_executable, check_writable)
4649 * lread.c (openp, load_path_check):
4650 * process.c (allocate_pty):
4652 Use effective UID when checking permissions, not real UID.
4653 * callproc.c (init_callproc):
4654 * charset.c (init_charset):
4655 * lread.c (load_path_check, init_lread):
4656 Test whether directories are accessible, not merely whether they exist.
4657 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4658 * fileio.c (check_existing, check_executable, check_writable)
4660 Use symbolic names instead of integers for the flags, as they're
4662 (check_writable): New arg AMODE. All uses changed.
4663 Set errno on failure.
4664 (Ffile_readable_p): Use faccessat, not stat + open + close.
4665 (Ffile_writable_p): No need to call check_existing + check_writable.
4666 Just call check_writable and then look at errno. This saves a syscall.
4667 dir should never be nil; replace an unnecessary runtime check
4668 with an eassert. When checking the parent directory of a nonexistent
4669 file, check that the directory is searchable as well as writable, as
4670 we can't create files in unsearchable directories.
4671 (file_directory_p): New function, which uses 'stat' on most platforms
4672 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4673 (Ffile_directory_p, Fset_file_times): Use it.
4674 (file_accessible_directory_p): New function, which uses a single
4675 syscall for efficiency.
4676 (Ffile_accessible_directory_p): Use it.
4677 * xrdb.c (file_p): Use file_directory_p.
4678 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4679 * lread.c (openp): When opening a file, use fstat rather than
4680 stat, as that avoids a permissions race. When not opening a file,
4681 use file_directory_p rather than stat.
4682 (dir_warning): First arg is now a usage string, not a format.
4683 Use errno. All uses changed.
4684 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4685 that merely introduced a race.
4686 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4687 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4688 and similarly for the other O_* flags.
4689 * w32.c (sys_faccessat): Rename from sys_access and switch to
4690 faccessat's API. All uses changed.
4691 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4692 (magic_db): Rename from magic_file_p.
4693 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4694 char *, so that we don't have to test for file existence
4695 separately from opening the file for reading. This removes a race
4696 fixes a permission-checking problem, and simplifies the code.
4698 (file_p): Remove; no longer needed.
4700 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4702 Omit glyphs initialization at startup.
4703 * dispnew.c (glyphs_initialized_initially_p): Remove.
4704 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4705 (Fredraw_frame): Move actual code from here...
4706 (redraw_frame): ...to here. Add eassert. Adjust comment.
4707 (Fredraw_display): Use redraw_frame.
4708 * xdisp.c (clear_garbaged_frames): Likewise.
4710 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4712 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4713 passed to pint2str and pint2hrstr to be at most the size of the
4714 frame's decode_mode_spec_buffer. This avoids crashes with very
4715 large values of FIELD_WIDTH argument to decode_mode_spec.
4718 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4720 Fix a race with verify-visited-file-modtime (Bug#12863).
4721 Since at least 1991 Emacs has ignored an mtime difference of no
4722 more than one second, but my guess is that this was to work around
4723 file system bugs that were fixed long ago. Since the race is
4724 causing problems now, let's remove that code.
4725 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4726 whose time stamp is off by no more than a second. Insist that the
4727 file time stamps match exactly.
4729 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4731 * frame.h (struct frame): Convert external_tool_bar member to
4732 1-bit unsigned bitfield.
4733 * termhooks.h (struct terminal): Remove mouse_moved member since
4734 all users are long dead. Adjust comment on mouse_position_hook.
4736 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4738 Simplify by using FOR_EACH_FRAME here and there.
4739 * frame.c (next_frame, prev_frame, other_visible_frames)
4740 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4741 * w32term.c (x_window_to_scroll_bar): Likewise.
4742 * window.c (window_list): Likewise.
4743 * xdisp.c (x_consider_frame_title): Likewise.
4744 * xfaces.c (Fdisplay_supports_face_attributes_p): Likewise.
4745 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4746 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4747 * xmenu.c (menubar_id_to_frame): Likewise.
4748 * xselect.c (frame_for_x_selection): Likewise.
4749 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4750 (x_window_to_menu_bar): Likewise.
4751 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4753 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4755 * data.c (Qdefalias_fset_function): Now static.
4757 Another tweak to vectorlike_header change.
4758 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4759 Remove, and replace all uses with ...
4760 (next_in_free_list, set_next_in_free_list):
4761 New functions, which respect C's aliasing rules better.
4763 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4765 * window.c (list4i): Rename from 'quad'. All uses changed.
4766 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4768 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4770 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4771 warning about mixing declarations and code in ISO C90.
4773 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4775 * window.c (Fsplit_window_internal): Set combination limit of
4776 new parent window to t iff Vwindow_combination_limit is t;
4777 fixing a regression introduced with the change from 2012-09-22.
4778 (Fset_window_combination_limit): Fix doc-string.
4780 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4782 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4783 amount when the scroll margins are too large. When scrolling
4784 backwards in the buffer, give up if cannot reach point or the
4785 scroll margin within a reasonable number of screen lines.
4786 Fixes point position in window under scroll-up/down-aggressively when
4787 point is positioned many lines beyond the window top/bottom.
4790 * ralloc.c (relinquish): If real_morecore fails to return memory
4791 to the system, don't crash; instead, leave the last heap
4792 unchanged and return. (Bug#12774)
4794 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4796 * lisp.h (AUTOLOADP): New macro.

4798 * data.c (Ffset): Remove special ad-advice-info handling.
4799 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4801 (Finteractive_form): Simplify.
4802 (Fquo): Don't insist on having at least 2 arguments.
4803 (Qdefalias_fset_function): New var.
4805 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4807 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4809 * nsfont.m (Qcondensed, Qexpanded): New variables.
4810 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4811 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4813 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4815 Fix recently introduced crash on MS-Windows (Bug#12839).
4816 * w32term.h (struct scroll_bar): Use convenient header.
4817 (SCROLL_BAR_VEC_SIZE): Remove.
4818 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4820 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4822 Tweak last vectorlike_header change.
4823 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4824 vectorlike object on the free list. This is introduced to avoid
4825 some (but not all) pointer casting and aliasing problems, see
4826 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4827 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4829 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4831 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4833 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4834 been removed, so remove them here also.
4836 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4838 * doc.c (Fdocumentation): Handle new property
4839 dynamic-docstring-function to replace the old ad-advice-info.
4841 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4843 * fns.c (Qeql, hashtest_eq): Now static.
4845 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4847 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4848 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4849 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4850 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4852 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>

4855 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4856 * lisp.h (sxhash_combine): New inline function, with the contents
4857 of the old SXHASH_COMBINE.
4858 * profiler.c (hashfn_profiler): Use it, instead of having a
4859 special hash function containing a comparison that always yields 1.
4861 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4863 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4864 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4865 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4868 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4870 * image.c (xpm_make_color_table_h): Fix compiler error because
4871 make_hash_table changed.
4873 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4875 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4877 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4879 Use ad-hoc comparison function for the profiler's hash-tables.
4880 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4881 (make_log): Use them.
4882 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4883 call Fequal any more.

4893 (hash_lookup, hash_remove_from_table): Move assertion checking of
4894 hashfn result here. Check hash-equality before calling cmpfn.

4931 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4932 (Fmake_bool_vector): Likewise.
4933 (struct large_vector): New type to represent allocation unit for
4934 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4935 (large_vectors): Change type to struct large_vector.
4936 (allocate_vector_from_block): Simplify.
4937 (PSEUDOVECTOR_NBYTES): Replace with...
4938 (vector_nbytes): ...new function. Adjust users.

4959 * keyboard.c (event_to_kboard): Do not dereference
4960 frame_or_window field of SELECTION_REQUEST_EVENT
4961 and SELECTION_CLEAR_EVENT events (Bug#12814).
4962 * xterm.h (struct selection_input_event): Adjust comment.
4964 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4966 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4967 such as Scroll Lock, if the respective keys are treated as
4968 function keys, not as modifiers. This avoids destroying non-ASCII
4969 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4971 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4973 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4975 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4977 Restore some duplicate definitions (Bug#12814).
4978 This undoes part of the 2012-11-03 changes. Some people build
4979 with plain -g rather than with -g3, and they need the duplicate
4980 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4981 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4982 Define as macros, as well as as enums or as constants.

4986 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4987 to keypad keys (Bug#12816).
4989 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4991 Minor adjustments of recently-changed frame functions.
4992 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4993 known to be a frame (we're in the FRAMEP branch).
4994 * lisp.h (Qframep): Remove decl. frame.h declares this.
4995 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4996 since they're meant for Lisp fixnum values.
4998 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
5000 * window.c (Fwindow_combination_limit): Revert to the only
5001 required argument and adjust docstring as suggested in
5002 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
5003 by Martin Rudalics <rudalics@gmx.at>.

5054 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
5056 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
5057 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
5058 file descriptor 2 for standard error. (Bug#12805)
5060 2012-11-05 Chong Yidong <cyd@gnu.org>
5062 * process.c (wait_reading_process_output): Revert previous change.
5064 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
5066 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
5067 This removes code that has been obsolete since around 1990.
5068 * callproc.c (Fcall_process):
5070 * process.c (create_process):
5071 * term.c (dissociate_if_controlling_tty):
5072 Assume setsid exists.
5073 * callproc.c (child_setup): Assume setpgid exists and behaves as
5074 per POSIX.1-1988 or later.
5075 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
5076 * emacs.c (shut_down_emacs):
5077 * sysdep.c (sys_suspend, init_foreground_group):
5078 Assume getpgrp behaves as per POSIX.1-1998 or later.
5079 * msdos.c (setpgrp): Remove.
5080 (tcgetpgrp, setpgid, setsid): New functions.
5081 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
5082 * term.c (no_controlling_tty): Remove; unused.
5083 * w32proc.c (setpgrp): Remove.
5084 (setsid, tcgetpgrp): New functions.
5086 Simplify by assuming __fpending.
5087 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
5088 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
5089 Do not assume that __fpending's result fits in int.
5091 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
5093 Remove EMACS_OUTQSIZE+sleep hack.
5094 * dispnew.c (update_frame_1): Remove hack for terminals slower
5095 than 2400 bps, which throttled Emacs by having it sleep.
5096 This code hasn't worked since at least 2007, when the multi-tty stuff
5097 was added, and anyway those old terminals are long dead.
5098 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
5099 without the dispnew.c change, as dispnew.c doesn't include systty.h.
5101 Fix data-loss with --version (Bug#9574).
5102 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
5103 as we can't assume that emacs_strerror is initialized, and strerror
5104 is good enough here.
5105 (main): Invoke atexit earlier, to catch earlier instances of
5106 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
5108 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
5110 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
5111 (keyDown): Remap keypad keys to X11 virtual key codes.
5113 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
5115 Fix data-loss with --batch (Bug#9574).
5116 * emacs.c: Include <close-stream.h>.
5117 (close_output_streams): New function.
5118 (main): Pass it to atexit, so that Emacs closes stdout and stderr
5119 and handles errors appropriately.
5120 (Fkill_emacs): Don't worry about flushing, as close_output_stream
5123 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
5124 The symptom is a diagnostic "GLib-WARNING **: In call to
5125 g_spawn_sync(), exit status of a child process was requested but
5126 SIGCHLD action was set to SIG_IGN and ECHILD was received by
5127 waitpid(), so exit status can't be returned." The diagnostic
5128 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
5129 The real bug is a race condition between Emacs and glib: Emacs
5130 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
5131 so that glib can't find it. Work around the bug by invoking
5132 waitpid only on subprocesses that Emacs itself creates.
5133 * process.c (create_process, record_child_status_change):
5134 Don't use special value -1 in pid field, as the caller now must
5135 know the pid rather than having the callee infer it.
5136 The inference was sometimes incorrect anyway, due to another race.
5137 (create_process): Set new 'alive' member if child is created.
5138 (process_status_retrieved): New function.
5139 (record_child_status_change): Use it.
5140 Accept negative 1st argument, which means to wait for the
5141 processes that Emacs already knows about. Move special-case code
5142 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
5143 processes that have already been waited for, by testing and
5144 clearing new 'alive' member.
5145 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
5146 now does this internally.
5147 (handle_child_signal): Let record_child_status_change do all
5148 the work, since we do not want to reap all exited child processes,
5149 only the child processes that Emacs itself created.
5150 * process.h (Lisp_Process): New boolean member 'alive'.
5152 Omit duplicate definitions no longer needed with gcc -g3.
5153 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
5154 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
5155 Define only as macros. There's no longer any need to also define
5156 these symbols as enums or as constants, since we now assume
5157 gcc -g3 when debugging.
5159 2012-11-03 Eli Zaretskii <eliz@gnu.org>
5161 * lisp.mk: Adjust comments to the fact that term/internal is now
5162 loaded from loadup.el.
5164 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5165 (msdos_fatal_signal): New function.
5166 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5169 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5170 for GCC versions before 4.
5171 (emacs_raise): Define to call msdos_fatal_signal.
5173 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5174 iterator when starting in the middle of a display or overlay
5177 2012-11-03 Chong Yidong <cyd@gnu.org>
5179 * process.c (wait_reading_process_output): Clean up the last
5182 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5184 * process.c (wait_reading_process_output): Avoid a race condition
5185 with SIGIO delivery (Bug#11536).
5187 2012-11-03 Chong Yidong <cyd@gnu.org>
5189 * buffer.c (cursor_type): Untabify docstring.
5191 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5193 * frame.h (struct frame): Drop can_have_scroll_bars member
5194 which is meaningless for a long time. Adjust comments.
5195 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
5196 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
5198 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5200 * window.c (decode_next_window_args): Update window arg after
5201 calling decode_live_window and so fix crash reported at
5202 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
5203 by Juanma Barranquero <lekktu@gmail.com>.
5204 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
5205 * font.c (Ffont_at): Likewise.
5207 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
5209 * widget.c (resize_cb): New function.
5210 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
5211 (EmacsFrameResize): Check if all is up to date before changing frame
5214 2012-11-02 Eli Zaretskii <eliz@gnu.org>
5216 Implement backtrace output for fatal errors on MS-Windows.
5217 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
5218 (BACKTRACE_LIMIT_MAX): New macro.
5219 (w32_backtrace): New function.
5220 (emacs_abort): Use w32_backtrace when the user chooses not to
5221 attach a debugger. Update the text of the abort dialog.
5223 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5225 Window-related stuff cleanup here and there.
5226 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
5227 Use decode_any_window.
5228 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
5229 * xdisp.c (Fformat_mode_line): Likewise.
5230 * font.c (Ffont_at): Use decode_live_window.
5231 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
5232 * window.c (decode_next_window_args): Likewise.
5233 (decode_any_window): Remove static.
5234 * window.h (decode_any_window): Add prototype.
5235 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
5236 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
5239 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5241 Remove pad from struct input_event.
5242 * termhooks.h (struct input_event): Remove padding field.
5244 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5245 member is never cons for a long time. Adjust comment.
5246 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5247 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5248 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5249 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5251 2012-11-01 Eli Zaretskii <eliz@gnu.org>
5253 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
5255 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5257 Fix crash when using Emacs as commit editor for git (Bug#12697).
5258 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5259 and it is configured in conf_post.h.
5260 (Fcall_process): Don't invoke both setsid and setpgid; the former
5261 is enough, if it exists.
5262 * callproc.c (Fcall_process, child_setup):
5263 * process.c (create_process): Use setpgid.
5264 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5266 * dispnew.c (init_display): Initialize the foreground group
5267 if we are running a tty display.
5268 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
5269 * lisp.h (init_foreground_group): New decl.
5270 * sysdep.c (inherited_pgroup): New static var.
5271 (init_foreground_group, tcsetpgrp_without_stopping)
5272 (narrow_foreground_group, widen_foreground_group): New functions.
5273 (init_sys_modes): Narrow foreground group.
5274 (reset_sys_modes): Widen foreground group.
5276 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
5278 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
5280 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5282 * minibuf.c (read_minibuf): Restore current buffer since
5283 choose_minibuf_frame calling Fset_frame_selected_window may
5284 change it (Bug#12766).
5286 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
5288 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
5290 2012-10-30 Kenichi Handa <handa@gnu.org>
5292 * font.c (Ffont_at): If WINDOW is specified and it is not
5293 displaying the current buffer, signal an error.
5295 2012-10-29 Daniel Colascione <dancol@dancol.org>
5297 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5298 In preparation for fixing bug#12739, move these functions from
5301 * coding.h, coding.c: ... to here, and compile them only when
5302 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5303 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5305 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5307 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5308 (timer_loop, getitimer, setitimer): Use it instead of
5309 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
5311 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
5314 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
5316 * nsterm.m (NO_APPDEFINED_DATA): New define.
5317 (last_appdefined_event_data): New variable
5318 (last_appdefined_event): Remove.
5319 (ns_select): Initialize t from last_appdefined_event_data instead
5320 of [last_appdefined_event data1].
5321 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
5322 remove last_appdefined_event (Bug#12698).
5324 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5326 * frame.c (x_set_font): Catch internal error.
5328 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5330 Avoid overflow in w32 implementation of interval timers.
5331 When possible, for ITIMER_PROF count only times the main thread
5333 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5334 'volatile ULONGLONG' types. All the other data which was
5335 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5336 (GetThreadTimes_Proc): New typedef.
5337 (w32_get_timer_time): New function, returns a suitable time value
5339 (timer_loop): Enter critical section when accessing ULONGLONG
5340 values of the itimer_data struct, as these accesses are no longer
5341 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5342 Remove unused variable.
5343 (init_timers): Initialize s_pfn_Get_Thread_Times.
5344 (start_timer_thread): Don't assign itimer->caller_thread here.
5345 (getitimer): Assign itimer->caller_thread here.
5346 (setitimer): Always call getitimer to get the value of ticks_now.
5347 (sys_spawnve): Avoid compiler warning about format mismatch.
5349 2012-10-26 Eli Zaretskii <eliz@gnu.org>
5351 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5352 mouse movement events if the menu bar is active. This avoids
5353 producing a busy "hour-glass" cursor by Windows if the mouse
5354 pointer is positioned over a tooltip shown for some menu item.
5356 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5358 Don't assume process IDs fit in int.
5359 * emacs.c (shut_down_emacs) [!DOS_NT]:
5360 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5361 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5362 Use pid_t, not int, to store process IDs, as 'int'
5363 is not wide enough on a few platforms (e.g., AIX and IRIX).
5365 2012-10-23 Kenichi Handa <handa@gnu.org>
5367 The following change is to make face-font-rescale-alist work
5368 correctly for non-ASCII fonts.
5370 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
5371 (font_open_for_lface): Handle Vface_font_rescale_alist.
5373 2012-10-23 Chong Yidong <cyd@gnu.org>
5375 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
5377 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
5379 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
5381 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
5383 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
5386 2012-10-21 Glenn Morris <rgm@gnu.org>
5388 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5390 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5392 Port to OpenBSD 5.1.
5393 * frame.c (Fmouse_position, Fmouse_pixel_position):
5394 * xdisp.c (produce_stretch_glyph):
5395 Declare local vars only when they're needed.
5396 This is clearer and avoids a warning on OpenBSD about unused vars.
5397 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
5398 This is safer, and avoids OpenBSD warnings about unused vars.
5399 * keyboard.c (record_menu_key): Remove unnecessary decl.
5400 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5401 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5402 as our definition clashes with OpenBSD's.
5403 * xfaces.c (load_face_colors, check_lface_attrs)
5404 (get_lface_attributes_no_remap, get_lface_attributes)
5405 (lface_fully_specified_p, x_supports_face_attributes_p)
5406 (tty_supports_face_attributes_p, face_fontset, realize_face)
5407 (realize_x_face, realize_tty_face):
5408 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5409 merely Lisp_Object *. This is more informative and avoids
5410 a warning on OpenBSD about accessing beyond an object's size.
5412 2012-10-20 Chong Yidong <cyd@gnu.org>
5414 * lread.c (Fload): Doc fix (Bug#12592).
5416 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
5418 * font.c (Ffont_at): Fix previous change.
5420 2012-10-19 Eli Zaretskii <eliz@gnu.org>
5422 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
5423 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
5426 * alloc.c (NSTATICS): Decrease to 0x800.
5428 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

5433 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
5435 * nsterm.m (ns_select): Check writefds before call to
5436 FD_ISSET (Bug#12668).
5438 2012-10-18 Daniel Colascione <dancol@dancol.org>
5440 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5441 (staticpro): If we run out of staticpro slots, die with an
5442 informative error instead of just calling emacs_abort.
5444 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5446 Fix two flaws reported by Dmitry Antipov.
5447 * window.c (Ftemp_output_buffer_show): Remove.
5448 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
5449 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
5451 2012-10-17 Eli Zaretskii <eliz@gnu.org>
5453 * makefile.w32-in ($(BLD)/w32.$(O)):
5454 ($(BLD)/vm-limit.$(O)):
5456 ($(BLD)/unexw32.$(O)):
5457 ($(BLD)/fileio.$(O)):
5458 ($(BLD)/dispnew.$(O)): Update dependencies.
5460 * w32term.h (w32_initialize_display_info, initialize_w32_display):
5463 * w32proc.c: Include ctype.h.
5465 * w32.h (init_environment, check_windows_init_file)
5466 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
5467 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
5468 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
5469 (sys_link): Add prototypes.
5471 * w32.c: Include w32select.h.
5472 (sys_access, e_malloc, sys_select): Add prototypes.
5473 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
5475 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
5477 * unexw32.c: Include lisp.h and w32.h.
5479 * term.c [WINDOWSNT]: Include w32term.h.
5481 * process.c [WINDOWSNT]: Add prototype of sys_select.
5483 * fileio.c [WINDOWSNT]: Include w32.h.
5485 * dispnew.c [WINDOWSNT]: Include w32.h.
5487 * cygw32.c (Fcygwin_convert_path_to_windows)
5488 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
5489 Lisp_Object values. (Bug#12661)
5491 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
5492 to Lisp_Object. (Bug#12661)
5494 2012-10-17 Kenichi Handa <handa@gnu.org>
5496 * xdisp.c (reseat_1): Make the information stored in it->cmp_it

5502 reset its buffer pointer to NULL (Bug#12652).
5504 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
5506 Do not verify indirection counters of killed buffers (Bug#12579).
5507 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
5508 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
5510 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
5512 * alloc.c (Fmake_byte_code): Fix typo in comment.
5513 * print.c (print_interval): Define as static to match prototype.
5514 * indent.c (disptab_matches_widthtab, recompute_width_table):
5517 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
5519 * editfns.c (get_system_name): Remove.
5520 * lisp.h (get_system_name): Remove prototype.
5521 * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes.

5526 * dbusbind.c: Add comment explaining reason for previous change.
5528 2012-10-15 Martin Rudalics <rudalics@gmx.at>
5530 * window.c (Fwindow_end): Rewrite check whether cached position
5531 can be used (Bug#12600).
5532 (resize_frame_windows, grow_mini_window, shrink_mini_window):
5533 Set windows_or_buffers_changed.
5535 2012-10-15 Daniel Colascione <dancol@dancol.org>
5537 * dbusbind.c: Fix cygw32 build break when compiling with dbus
5538 enabled by undefining the symbol "interface", which the platform
5539 headers define to something incompatible.
5541 2012-10-14 Daniel Colascione <dancol@dancol.org>
5543 * image.c (init_tiff_functions, init_imagemagick_functions)

5566 Fix some stat-related races.
5567 * fileio.c (Fwrite_region): Avoid race condition if a file is
5568 removed or renamed by some other process immediately after Emacs
5569 writes it but before Emacs stats it. Do not assume that stat (or
5571 * image.c (slurp_file): Resolve the file name with fopen + fstat
5572 rather than stat + fopen.

5598 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
5600 * fileio.c (check_existing): New function.
5601 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
5602 instead of calling 'stat', when what's needed is to check whether
5603 a file exists. This avoids expensive system calls on MS-Windows.
5606 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
5608 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

5697 * keyboard.c (timers_run, swallow_events)
5698 (detect_input_pending_run_timers):
5699 * process.c (wait_reading_process_output):
5700 Use unsigned for counter where wraparound-on-overflow is desired,
5701 since unsigned is guaranteed to have that behavior and signed is not.
5702 (read_char): Use ptrdiff_t for string length.
5703 (get_input_pending): Remove first argument, since it was always
5704 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5705 and behave as if it had that value. Return new value of
5706 input_pending. All callers changed.
5707 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5708 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5710 * keymap.c (push_key_description): Omit last arg, which was always 1.
5711 All callers changed.
5713 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
5715 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

5731 Don't include termopts.h.
5733 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5735 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5737 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5739 * commands.h (immediate_quit): Remove duplicate decl.
5741 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5743 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
5745 (nsfont_open): Remove setting of Vfonts_in_cache.
5746 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5748 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5750 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5751 match what GetLastError returns. Explain why the function is
5754 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5755 'is_tooltip_frame', to avoid confusion with its global namesake.
5757 2012-10-08 Daniel Colascione <dancol@dancol.org>
5759 * xdisp.c (start_hourglass): Call w32_note_current_window when
5760 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5761 build that caused Emacs to display the hourglass cursor forever.
5763 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5764 which is broken under remote desktop, calculate the number of
5765 colors available for a display based on the display's number of
5766 planes and number of bits per pixel per plane. (bug#10397).
5768 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5770 * nsfont.m (Vfonts_in_cache): New variable.
5771 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5772 are used. Add cached fonts to Vfonts_in_cache.
5773 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5775 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5777 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5779 (FONT_H): Define after FRAME_H.
5780 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5781 Update dependencies.
5783 * w32term.c: Remove leftover declaration of keyboard_codepage.
5785 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5787 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5788 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5789 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5790 (GLOBAL_SOURCES): Add cygw32.c.
5791 ($(BLD)/unexw32.$(O)):
5793 ($(BLD)/w32console.$(O)):
5794 ($(BLD)/w32fns.$(O)):
5795 ($(BLD)/w32heap.$(O)):
5796 ($(BLD)/w32menu.$(O)):
5797 ($(BLD)/w32proc.$(O)): Add w32common.h.
5799 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5801 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5803 2012-10-08 Daniel Colascione <dancol@dancol.org>
5805 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5806 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5807 accidental message numbering hole. Change other messages to
5810 * w32select.h (HAVE_W32SELECT): Remove.
5812 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5813 w32common.h instead of w32heap.h.
5815 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5816 (get_allocation_unit, get_processor_type, get_w32_major_version)
5817 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5818 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5819 (OS_NT, os_subtype, cache_system_info): Move declarations to
5822 * w32heap.c: Include w32common.h.
5823 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5824 (w32_minor_version, w32_build_number, w32_subtype):
5825 Remove duplicate definitions.
5827 * w32fns.c: Include w32common.h; include w32heap.h only in
5830 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5831 Use `report_file_error' instead of `error' in order to better
5832 inform users of what went wrong. Increase NTGUI_UNICODE file
5833 dialog box file name length to 32k, the maximum allowed by the NT
5836 * w32common.h: New file.
5837 (ROUND_UP, ROUND_DOWN, get_page_size)
5838 (get_allocation_unit, get_processor_type, get_w32_major_version)
5839 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5840 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5841 (OS_NT, os_subtype, cache_system_info): Move here.
5843 * unexw32.c, unexcw.c: Include w32common.h.
5845 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5846 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5847 to call syms_of_w32select.
5849 * cygw32.h: Remove obsolete EXFUN declarations.
5851 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5853 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5854 of w32inevt.o from SOME_MACHINE_OBJECTS.
5856 2012-10-08 Daniel Colascione <dancol@dancol.org>
5858 * image.c: Permanent fix for JPEG compilation issue --- limit
5859 jpeglib `boolean' redefinition to Cygwin builds.
5861 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5863 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5865 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5868 2012-10-08 Daniel Colascione <dancol@dancol.org>
5870 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5871 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5872 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5873 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5874 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5875 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5876 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5877 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5878 now a supported configuration.
5880 * Makefile.in: consolidate image variables into LIBIMAGE; add
5881 W32_OBJ and W32_LIBS. Compile new files.
5884 (_DebPrint) declare tracing facility for W32 debugging. We need
5885 to unify tracing later.
5887 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5888 unconditional use of W32 Unicode functions. Cygwin runs only on
5889 100% Unicode operating systems.
5891 * cygw32.c: New file. Define Cygwin-specific facilities.
5892 (Fcygwin_convert_path_to_windows)
5893 (Fcygwin_convert_path_from_windows): New user functions for
5894 accessing Cygwin path-munging routines.
5896 * cygw32.h: New file.
5897 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5898 UTF-16LE strings temporarily inside non-Lisp-visible string
5901 (w32_strerror): Just what it says on the tin.
5903 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5904 also run for Cygwin; both systems have the same problem with using
5905 GUI facilities in a forked child. Also call syms_of_cygw32,
5906 syms_of_w32select in correct places.
5908 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5909 needs fork-then-exec for daemon launching.
5911 * font.h: Include frame.h.
5913 * image.c: Use the image library cache machinery only when we're
5914 compiling for native WINDOWSNT; Cygwin can use shared libraries
5915 like any other Unixlike system.
5917 * keyboard.c: Clarify a comment regarding the input loop.
5919 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5920 functions directly instead of trying to detect at runtime that our
5921 host operating system supports them. We make this change for two
5922 reasons: Cygwin lacks support for the multibyte character
5923 conversion functions used by the legacy menu code, and Cygwin
5924 never needs to rely on non-Unicode APIs.
5926 * unexw32.c (hinst): Declare extern.
5928 * w32.c: Change header order;
5929 (w32_strerror): Move to w32fns.c because we need it for
5930 non-WINDOWSNT builds.
5932 * w32.h: Add #error macro to make sure we don't include w32.h for
5933 Cygwin builds. Remove w32select declarations.
5935 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5936 w32fns.c. w32console.c is WINDOWSNT-only.
5938 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5939 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5941 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5942 (w32_major_version, w32_minor_version, w32_build_number)
5943 (os_subtype, sound_type): Define here
5944 (w32_defined_color): Make color parameter const for consistency
5945 with other _defined_color functions.
5946 (w32_createwindow): Unconditionally call w32_init_class instead of
5947 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5948 through the code is complex and unnecessary because class
5949 registration is practically free.
5950 (w32_name_of_message): New EMACSDEBUG-only function.
5951 (Fset_message_beep): Move here
5952 (Fx_open_connection): Require that the display name for Windows be
5953 "w32" for consistency, emacsclient disambiguation, and maybe, one
5954 day, multi-window-system support.
5955 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5956 Cygwin files for W32 GUI facilities, since these clearly don't
5957 expect Cygwin names.
5958 (_DebPrint): Define.
5959 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5960 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5961 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5962 (w32_last_error): Remove.
5964 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5966 * w32heap.c (syspage_mask): Declare here.
5967 (cache_system_info): Remove.
5969 * w32inevt.c (faked_key): Define globally, not statically.
5970 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5971 (w32_console_toggle_lock_key): Move to w32fns.c.
5973 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5975 * w32proc.c (_DebPrint): Move to w32fns.c.
5976 * w32select.c: Include string.h, stdio.h for Cygwin.
5977 * w32select.h: New File.
5979 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5981 (w32_message_fd): New variable. Under Cygwin, holds the file
5982 descriptor the system used to tell us about pending thread
5985 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5986 that prevented compilation under non-WINDOWSNT systems.
5988 (w32_initialize): Open /dev/windows and assign it to
5989 w32_message_fd. Provide w32 feature.
5991 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5992 (WM_EMACS_INPUT_READY): add.
5993 (prepend_msg, w32_message_fd): Declare globally.
5996 (keyboard_handle): Use only when WINDOWSNT.
5997 (notify_msg_ready): New function. Posts a message to the main
5998 thread's message queue under CYGWIN, which wakes up the main
5999 thread from select(2) by making the /dev/windows file descriptor
6000 ready. Under WINDOWSNT, it sets an event the same way the old
6003 (post, prepend_msg): Actually call notify_msg_ready instead of
6004 setting the input event directly.
6006 2012-10-07 Eli Zaretskii <eliz@gnu.org>
6008 * ralloc.c (relinquish): If a heap is ready to be relinquished,
6009 but it still has blocs in it, don't return it to the system,
6010 instead of aborting. (Bug#12402)
6012 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
6014 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

6045 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
6047 Improve sys_siglist detection.
6048 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
6049 defined as a macro, as is done in Solaris.
6050 (sys_siglist_entries): New macro.
6051 (save_strsignal): Use it.
6052 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
6053 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
6055 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
6057 * nsfns.m (Fx_create_frame): Call x_default_parameter with
6058 fullscreen/Fullscreen.
6060 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
6061 tobar_height is new.
6063 * nsterm.m (x_make_frame_visible): Check for fullscreen.
6064 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
6065 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

6078 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
6080 2012-10-05 Eli Zaretskii <eliz@gnu.org>
6082 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
6084 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
6085 that time stamps of directories could also be changed.
6086 Don't request the too broad GENERIC_WRITE, only the more restrictive
6087 FILE_WRITE_ATTRIBUTES access rights.
6089 * fileio.c (Fset_file_times): Special-case ignoring errors for
6090 directories only on MSDOS, not on MS-Windows.
6092 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
6094 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
6096 2012-10-04 Eli Zaretskii <eliz@gnu.org>
6098 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
6099 see whether CreateFile failed.
6101 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
6103 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
6104 to avoid similar races.
6105 * keyboard.c (pending_signals): Now bool, not int.
6107 Port timers to OpenBSD, plus check for timer failures.
6108 OpenBSD problem reported by Han Boetes.
6109 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
6111 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
6112 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
6113 like OpenBSD, which has timer_settime but does not declare it.
6114 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
6115 whether to use itimerspec-related primitives. All uses of
6116 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
6118 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6120 * profiler.c (handle_profiler_signal): Fix a malloc race
6121 that caused Emacs to hang on Fedora 17 when profiling Lisp.

6125 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
6127 2012-10-02 Eli Zaretskii <eliz@gnu.org>
6129 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
6130 consistent with the change in return value of 'safe_strsignal'.
6132 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6134 Prefer plain 'static' to 'static inline' (Bug#12541).
6135 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
6136 (bidi_set_sor_type, bidi_push_embedding_level)
6137 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

6142 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6143 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
6144 Now 'static', not 'static inline'.
6146 Count overruns when profiling; change units to ns.
6147 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
6148 Give extra weight to samples after overruns, to attempt to count
6149 the time more accurately.
6150 (setup_cpu_timer): Change sampling interval units from ms to ns, since
6151 the underlying primitives nominally do ns.
6152 (Fprofiler_cpu_start): Document the change. Mention that
6153 the sampling intervals are only approximate.
6155 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6157 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
6159 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
6160 case for the special 0 coding-system.
6162 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
6163 (Fmake_overlay): Remove redundant tests.
6164 (fix_start_end_in_overlays): Remove redundant recentering.
6166 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
6168 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
6169 Update dependencies.
6171 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6173 Fix a malloc race condition involving strsignal.
6174 A signal can arrive in the middle of a malloc, and Emacs's signal
6175 handler can invoke strsignal, which can invoke malloc, which is
6176 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6177 Fix it by altering the signal handler so that it does not invoke
6179 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6180 * process.c (status_message): Use const pointer, in case strsignal
6181 is #defined to safe_strsignal.
6182 * sysdep.c (sys_siglist, init_signals): Always define and
6183 initialize a substitute sys_siglist if the system does not define
6184 one, even if HAVE_STRSIGNAL.
6185 (safe_strsignal): Rename from strsignal. Always define,
6186 using sys_siglist. Return a const pointer.
6187 * syssignal.h (safe_strsignal): New decl.
6188 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6190 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6192 * w32proc.c (timer_loop): Fix code that waits for timer
6193 expiration, to avoid high CPU usage.
6195 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6197 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6198 (sweep_weak_table): Remove redundant prototypes.
6200 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6202 * emacs.c: Move the inclusion of TERM_HEADER after including
6203 windows.h on WINDOWSNT. This avoids compilation problems with
6206 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6208 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6209 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6210 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6211 as the previous version used 'void *'.
6213 * ralloc.c (ROUNDUP): Fix last change.
6214 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6217 * w32proc.c <disable_itimers>: New static flag.
6218 (init_timers): Initialize it to zero, after creating the critical
6219 sections used by the timer threads.
6220 (term_timers): Set to 1 before deleting the critical sections.
6221 (getitimer, setitimer): If disable_itimers is non-zero, return an
6222 error indication without doing anything. Reported by Fabrice
6223 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6224 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6226 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6229 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6230 term_ntproc after all the other bookkeeping, to get timers working
6231 as long as possible.
6233 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6235 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6236 Suggested by Juri Linkov in
6237 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6239 Prefer plain 'static' to 'static inline' (Bug#12541).
6240 With static functions, modern compilers inline pretty well by
6241 themselves; advice from programmers often hurts as much as it helps.
6242 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6243 this change shrinks the text size of the Emacs executable by 1.1%
6244 without affecting CPU significantly in my benchmark.
6245 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

6325 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
6327 Revert the FOLLOW-SYMLINKS change for file-attributes.
6328 Doing it right would require several changes to Tramp, and there's
6329 not enough time to get that tested before the freeze today.
6330 * dired.c (directory_files_internal, Ffile_attributes):
6333 * frame.c (x_report_frame_params): Port better to wider ints.
6334 Do not assume that EMACS_UINT is the same width as uprintmax_t,
6335 or that pointers can be printed in 15 decimal digits.
6336 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

6372 * vm-limit.c (lim_data): Now size_t.
6373 (check_memory_limits): Adjust prototypes of real_morecore and
6374 __morecore to receive argument of type ptrdiff_t. Use size_t for

6445 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
6446 to hourglass timer expiration.
6447 (start_hourglass, cancel_hourglass, DEFAULT_HOURGLASS_DELAY):
6448 Remove, no longer used.
6449 (w32_note_current_window, show_hourglass, hide_hourglass):
6450 New functions, in support of hourglass cursor display similar to other

6463 to the buffer relocation which may be caused by ccl_driver.
6465 2012-09-30 Jan Djärv <jan.h.d@swipnet.se>
6467 * xfns.c (Fx_file_dialog): Update comment.
6469 * w32fns.c (Fx_file_dialog): Update comment.

6499 (EmacsFSWindow): New interface for fullscreen.
6501 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
6503 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
6505 2012-09-30 Chong Yidong <cyd@gnu.org>
6507 * fns.c (Frandom): Doc fix.
6509 2012-09-30 Martin Rudalics <rudalics@gmx.at>
6511 * window.c (Vwindow_combination_limit): New default value.
6512 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
6514 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6516 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
6517 Suggested by Eli Zaretskii in
6518 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
6520 2012-09-30 Eli Zaretskii <eliz@gnu.org>
6522 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
6523 HAVE_TIMER_SETTIME is defined.
6525 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6527 Profiler improvements: more-accurate timers, overflow checks.
6528 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6529 signal.h, setjmp.h. Include systime.h instead.
6530 (saturated_add): New function.
6531 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
6532 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
6533 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
6535 (enum profiler_cpu_running): New enum.
6536 (profiler_cpu_running): Now of that enum type, not bool.
6537 All uses changed to store the new value.
6538 (handle_profiler_signal): Rename from sigprof_handler_1,
6539 for consistency with other handlers. Do not check whether
6540 cpu_log is a hash-table if garbage collecting, since it
6541 doesn't matter in that case.
6542 (deliver_profiler_signal): Rename from sigprof_handler,
6543 for consistency with other handlers.
6544 (setup_cpu_timer): New function, with much of what used to be in
6545 Fprofiler_cpu_start. Check for out-of-range argument.
6546 Prefer timer_settime if available, and prefer
6547 thread cputime clocks, then process cputime clocks, then
6548 monotonic clocks, to the old realtime clock. Use make_timeval
6549 to round more-correctly when falling back to setitimer.
6550 (Fprofiler_cpu_start): Use it.
6551 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6552 Don't assume that passing NULL as the 2nd argument of setitimer
6553 is the same as passing a pointer to all-zero storage.
6554 Ignore SIGPROF afterwards.
6555 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6556 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6557 non-fatal signal handlers. Ignore SIGPROF on startup.
6558 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6559 in profiler.c, since sysdep.c now uses it.
6561 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
6562 Suggested by Eli Zaretskii in
6563 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

6585 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
6586 Qautomatic_redisplay and change the symbol name. All users changed.

6615 * character.h (MAYBE_UNIFY_CHAR): Remove.
6616 * charset.c, charset.h (maybe_unify_char): Now static.
6617 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6618 Since this stuff is now private to charset.c, there's no need for
6619 a public macro and no need to inline by hand.
6621 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>

6652 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6654 Prefer POSIX timers if available.
6655 They avoid a race if the timer is too close to the current time.
6656 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6657 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
6658 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
6660 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6662 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
6663 CHAR_STRING_ADVANCE.
6664 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
6665 STRING_CHAR_ADVANCE.

6683 * w32.h (Vlibrary_cache): Do not declare.
6685 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6687 * w32proc.c (sys_signal): Handle all signals defined by the
6688 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6689 handlers for signals supported by Windows. Don't override
6690 term_ntproc as the handler for SIGABRT.
6691 (sigaction): Rewrite to call sys_signal instead of duplicating its
6693 (sys_kill): Improve commentary.
6695 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6696 consistency with a signature of a signal handler. All callers
6698 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6699 install term_ntproc as a signal handler for SIGABRT, as that
6700 should be done by the dumped Emacs.
6702 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6704 * w32select.c (term_w32select): Protect against repeated
6705 invocation by setting clipboard_owner to NULL after calling
6708 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6709 and term_ntproc to their modified signatures.
6711 * character.c (char_string, string_char): Remove calls to
6712 MAYBE_UNIFY_CHAR. See the discussion starting at

6720 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6722 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6723 when encountering an unknown bytecode.
6725 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6727 image.c, indent.c: Use bool for booleans.
6728 * dispextern.h (struct image_type): Members valid_p, load, init

6730 * image.c: Omit unnecessary static decls.
6731 (x_create_bitmap_mask, x_build_heuristic_mask):

6769 Move pid_t related decls out of lisp.h.
6770 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6771 (interruptible_wait_for_termination):
6772 Move these decls from lisp.h to syswait.h, since they use pid_t.
6773 Needed on FreeBSD; see Herbert J. Skuhra in
6774 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6775 * callproc.c: Include syswait.h.

6821 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6823 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6824 fatal_error_backtrace.
6826 * w32proc.c (sys_kill): Undo last change: don't do anything when
6827 invoked to deliver SIGABRT to our own process. This is now
6828 handled by emacs_raise.
6830 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6832 * w32term.c (w32_read_socket): Remove leftover reference to
6833 interrupt_input_pending.
6835 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6837 Do not use SA_NODEFER.
6838 Problem reported by Dani Moncayo in
6839 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6841 * sysdep.c (emacs_abort): Do not reset signal handler.
6842 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6843 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6844 wanted even on POSIXish hosts, and it doesn't work on Windows.
6846 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6848 * xterm.c (x_term_init): Call fixup_locale before and after calling
6849 gtk_init (Bug#12392).
6851 2012-09-23 Chong Yidong <cyd@gnu.org>
6853 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6854 Vdynamic_library_alist.
6856 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6857 (Fgnutls_available_p): Caller changed.
6859 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6860 (Flibxml_parse_xml_region): Likewise.
6862 * dispextern.h (struct image_type): Remove arg from init function.
6864 * image.c (Finit_image_library, lookup_image_type)
6865 (define_image_type): Remove now-unneeded second arg.
6866 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6867 (init_tiff_functions, init_gif_functions, init_svg_functions):
6868 Arglist and w32_delayed_load calling convention changed.
6869 (gs_type): Remove init_gs_functions; there is no such function.
6870 (valid_image_p, make_image): Fix caller to lookup_image_type.
6872 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6874 Simplify and avoid signal-handling races (Bug#12471).
6876 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6877 Avoid recursive loop if there's a fatal error in the function itself.
6878 * atimer.c (pending_atimers):
6879 * blockinput.h: Don't include "atimer.h"; no longer needed.
6880 (interrupt_input_pending): Remove. All uses removed.
6881 pending_signals now counts both atimers and ordinary interrupts.
6882 This is less racy than having three separate pending-signal flags.
6883 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6885 Rename from their upper-case counterparts BLOCK_INPUT,
6886 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6887 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6888 This makes it easier to access volatile variables more accurately.
6889 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6890 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6891 that's more reliable if the code is buggy and sets
6892 interrupt_input_blocked to a negative value. All uses changed.
6893 * atimer.c (deliver_alarm_signal):
6894 Remove. No need to deliver this to the parent; any thread can
6895 handle this signal now. All uses replaced by underlying handler.
6896 * atimer.c (turn_on_atimers):
6897 * dispnew.c (handle_window_change_signal):
6898 * emacs.c (handle_danger_signal):
6899 * keyboard.c (kbd_buffer_get_event):
6900 Don't reestablish signal handler; not needed with sigaction.
6901 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6903 Rework to avoid unnecessary accesses to volatile variables.
6904 (UNBLOCK_INPUT_TO): Now a function.
6905 (totally_unblock_input, unblock_input): New decls.
6906 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6907 (init_data): Remove. Necessary stuff now done in init_signal.
6908 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6909 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6910 (fatal_error_code): Remove; no longer needed.
6911 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6912 it doesn't always backtrace. All uses changed. No need to reset
6913 signal to default, since sigaction and/or die does that for us now.
6914 Use emacs_raise (FOO), not kill (getpid (), FOO).
6915 (main): Check more-accurately whether we're dumping.
6916 Move fatal-error setup to sysdep.c
6917 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6918 * gtkutil.c (xg_get_file_name, xg_get_font):
6919 Remove no-longer-needed signal-mask manipulation.
6920 * keyboard.c, process.c (POLL_FOR_INPUT):
6921 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6922 * keyboard.c (read_avail_input): Remove.
6923 All uses replaced by gobble_input.
6924 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6925 (kbd_buffer_store_event_hold, gobble_input):
6926 (record_asynch_buffer_change) [USABLE_SIGIO]:
6927 (store_user_signal_events):
6928 No need to mess with signal mask.
6929 (gobble_input): If blocking input and there are terminals, simply
6930 set pending_signals to 1 and return. All hooks changed to not
6931 worry about whether input is blocked.
6932 (process_pending_signals): Clear pending_signals before processing
6933 them, in case a signal comes in while we're processing.
6934 By convention callers now test pending_signals before calling us.
6935 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6936 New functions, to support changes to blockinput.h.
6937 (handle_input_available_signal): Now extern.
6938 (reinvoke_input_signal): Remove. All uses replaced by
6940 (quit_count): Now volatile, since a signal handler uses it.
6941 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6942 All callers changed. Block SIGINT only if not already blocked.
6943 Clear sigmask reliably, even if Fsignal returns, which it can.
6944 Omit unnecessary accesses to volatile var.
6945 (quit_throw_to_read_char): No need to restore sigmask.
6946 * keyboard.c (gobble_input, handle_user_signal):
6947 * process.c (wait_reading_process_output):
6948 Call signal-handling code rather than killing ourselves.
6949 * lisp.h: Include <float.h>, for...
6950 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6951 (pending_signals): Now volatile.
6952 (syms_of_data): Now const if IEEE floating point.
6953 (handle_input_available_signal) [USABLE_SIGIO]:
6954 (terminate_due_to_signal, record_child_status_change): New decls.
6955 * process.c (create_process): Avoid disaster if memory is exhausted
6956 while we're processing a vfork, by tightening the critical section
6958 (send_process_frame, process_sent_to, handle_pipe_signal)
6959 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6961 (send_process): No need for setjmp/longjmp any more, since the
6962 SIGPIPE stuff is now gone. Instead, report an error if errno
6964 (record_child_status_change): Now extern. PID and W are now args.
6965 Return void, not bool. All callers changed.
6966 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6967 Remove. All uses removed. This bug should be fixed now in a
6969 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6970 and record the child status change directly. This avoids the
6971 need to futz with the signal mask.
6972 (process_fatal_action): Move here from emacs.c.
6973 (emacs_sigaction_flags): New function, containing
6974 much of what used to be in emacs_sigaction_init.
6975 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6976 caught by emacs, to make races less likely.
6977 (deliver_process_signal): Rename from handle_on_main_thread.
6979 (BACKTRACE_LIMIT_MAX): Now at top level.
6980 (thread_backtrace_buffer, threadback_backtrace_pointers):
6982 (deliver_thread_signal, deliver_fatal_thread_signal):
6983 New functions, for more-accurate delivery of thread-specific signals.
6984 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6985 (deliver_arith_signal): Handle in this thread, not
6986 in the main thread, since it's triggered by this thread.
6987 (maybe_fatal_sig): New function.
6988 (init_signals): New arg DUMPING so that we can be more accurate
6989 about whether we're dumping. Caller changed.
6990 Treat thread-specific signals differently from process-general signals.
6991 Block all signals while handling fatal error; that's safer.
6992 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6994 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6995 Ignore SIGPIPE unless batch.
6996 (emacs_backtrace): Output backtrace for the appropriate thread,
6997 which is not necessarily the main thread.
6998 * syssignal.h: Include <stdbool.h>.
6999 (emacs_raise): New macro.
7000 * xterm.c (x_connection_signal): Remove; no longer needed
7001 now that we use sigaction.
7002 (x_connection_closed): No need to mess with sigmask now.
7003 (x_initialize): No need to reset SIGPIPE handler here, since
7004 init_signals does this for us now.
7006 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
7008 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
7009 background rect may be larger (Bug#12245).
7011 2012-09-23 Chong Yidong <cyd@gnu.org>
7013 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
7015 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7017 * .gdbinit: Just stop at fatal_error_backtrace.
7018 See Stefan Monnier's request in
7019 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
7020 Remove no-longer-used query of system type.
7022 2012-09-22 Chong Yidong <cyd@gnu.org>
7024 * search.c (Freplace_match): Doc fix (Bug#12325).
7026 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
7028 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
7029 (Fline_end_position): Doc fix.
7031 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
7033 2012-09-22 Chong Yidong <cyd@gnu.org>
7035 * dispextern.h (struct image_type): Add new slot, storing a type
7036 initialization function.
7038 * image.c (define_image_type): Call the image initializer function
7039 if it is defined. Arguments and return value changed.
7040 (valid_image_p, make_image): Callers changed.
7041 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
7042 (gif_type, imagemagick_type, svg_type, gs_type):
7043 Add initialization functions.
7044 (Finit_image_library): Call lookup_image_type.
7045 (CHECK_LIB_AVAILABLE): Macro deleted.
7046 (lookup_image_type): Call define_image_type here, rather than via
7047 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
7048 (syms_of_image): Move define_image_type calls for xbm_type and
7049 pbm_type to lookup_image_type.
7051 2012-09-22 Eli Zaretskii <eliz@gnu.org>
7053 * keyboard.c (timer_check_2): Move calculation of 'timers' and
7054 'idle_timers' from here ...
7055 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
7056 lists, to avoid infloops when the timer does something stupid,
7057 like reinvoke itself with the same or smaller time-out.
7060 2012-09-22 Martin Rudalics <rudalics@gmx.at>
7062 * window.c (Fsplit_window_internal): Handle only Qt value of
7063 Vwindow_combination_limit separately.
7064 (Qtemp_buffer_resize): New symbol.
7065 (Vwindow_combination_limit): New default value.
7068 2012-09-22 Eli Zaretskii <eliz@gnu.org>
7070 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
7071 the new overlay string. (Bug#10159)
7073 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7075 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
7076 or that fprintf is async-signal-safe. POSIX doesn't require
7079 2012-09-22 Chong Yidong <cyd@gnu.org>
7081 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
7084 2012-09-22 Kenichi Handa <handa@gnu.org>
7086 * composite.c (composition_reseat_it): Handle the case that a
7087 grapheme cluster is not covered by a single font (Bug#12352).
7089 2012-09-21 Chong Yidong <cyd@gnu.org>
7091 * image.c (define_image_type): Avoid adding duplicate types to
7092 image_types (Bug#12463). Suggested by Jörg Walter.
7094 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7096 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
7097 (print_load_command_name): Add case LC_DATA_IN_CODE.
7098 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
7100 2012-09-21 Glenn Morris <rgm@gnu.org>
7102 * eval.c (Frun_hook_with_args_until_success)
7103 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
7105 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
7107 * fileio.c (Ffile_selinux_context): Only call freecon when
7108 lgetfilecon succeeded.
7109 (Fset_file_selinux_context): Likewise. (Bug#12444)
7111 2012-09-21 Eli Zaretskii <eliz@gnu.org>
7113 * xdisp.c (try_window_reusing_current_matrix): Under bidi
7114 reordering, locate the cursor by calling set_cursor_from_row; if
7115 that fails, clear the desired glyph matrix before returning a
7116 failure indication to the caller. Fixes leaving garbled display
7117 when fast scrolling with a down-key. (Bug#12403)
7118 (compute_stop_pos_backwards): Fix a typo that caused crashes while
7119 scrolling through multibyte text.
7121 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
7123 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
7124 calling mark_vectorlike since that's the one that marks the window.
7125 (mark_discard_killed_buffers): Mark the final cdr.
7126 * window.h (struct window): Move prev/next_buffers to the
7127 non-standard fields.
7128 * window.c (make_window): Initialize prev/next_buffers manually.
7130 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
7132 Omit unused arg EXPECTED from socket hooks.
7133 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
7134 * nsterm.m (ns_term_init):
7135 * termhooks.h (struct terminal.read_socket_hook):
7136 * w32inevt.c (w32_console_read_socket):
7137 * w32term.c (w32_read_socket):
7138 * xterm.c (XTread_socket):
7139 Omit unused arg EXPECTED. All callers changed.
7140 (store_user_signal_events): Return void, not int, since callers no
7141 longer care about the return value. All uses changed.
7143 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
7145 * w32gui.h (XParseGeometry): Do not declare.
7147 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
7149 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
7150 Ignore 'expected'. See Eli Zaretskii in
7151 <http://bugs.gnu.org/12471#8> (last line).
7153 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
7154 (XParseGeometry): Now static. Substitute extremal values for
7155 values that are out of range.
7157 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7159 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7161 * nsfns.m (XParseGeometry): Remove.
7162 (Fx_create_frame): Call x_set_offset to correctly interpret
7163 top_pos in geometry.
7165 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7166 (Fx_parse_geometry): If there is a space in string, call
7167 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7169 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7171 * search.c (scan_buffer): Use character positions in calls to
7172 region_cache_forward and region_cache_backward, not byte
7173 positions. (Bug#12196)
7175 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7176 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7178 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7179 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7180 emacs_blocked_malloc, now deleted.
7182 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7184 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7185 The workaround was for improving performance on Solaris 2.4, but
7186 is getting in the way now. Emacs will still work if someone is
7187 still running Solaris 2.4 in a museum somewhere; Sun dropped
7188 support for Solaris 2.4 in 2003.
7189 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7190 * process.c (create_process) [HAVE_WORKING_VFORK]:
7191 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7192 since Emacs no longer uses vfork on that platform.
7194 2012-09-17 Glenn Morris <rgm@gnu.org>
7196 * emacs.c: Use COPYRIGHT.
7198 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7200 Remove configure's --without-sync-input option (Bug#12450).
7201 When auditing signal-handling in preparation for cleaning it up,
7202 I found that SYNC_INPUT has race conditions and would be a real
7203 pain to fix. Since it's an undocumented and deprecated
7204 configure-time option, now seems like a good time to remove it.
7205 Also see <http://bugs.gnu.org/11080#16>.
7206 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7207 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7208 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7209 (malloc_hysteresis):
7210 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7211 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7212 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7213 (dont_register_blocks, bytes_used_when_reconsidered)
7214 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7215 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7216 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7217 Remove. All uses removed.
7218 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7219 implementation, one that depends on whether the new macro
7220 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7222 * atimer.c (run_timers, handle_alarm_signal):
7223 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7224 (handle_async_input, process_pending_signals)
7225 (handle_input_available_signal, init_keyboard):
7226 * nsterm.m (ns_read_socket):
7227 * process.c (wait_reading_process_output):
7228 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7229 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7231 * xterm.c (XTread_socket):
7233 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7234 * eval.c (handling_signal): Remove. All uses removed.
7235 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7236 All uses replaced with the SYNC_INPUT version.
7237 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7239 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7242 * font.c (Ffont_shape_gstring): Remove unused local.
7244 2012-09-16 Glenn Morris <rgm@gnu.org>
7246 * Makefile.in (clean): No longer run nextstep's clean.
7248 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7250 (ns-app): Move here from ns.mk, and simplify.
7251 (clean): Simplify nextstep entry.
7252 * ns.mk: Remove file.
7254 2012-09-17 Kenichi Handa <handa@gnu.org>
7256 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7257 not covert the last few charactes.
7259 2012-09-16 Kenichi Handa <handa@gnu.org>
7261 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7262 here, but just check the validity of glyphs in the glyph-string.
7264 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7266 * window.c (Fwindow_parameter, Fset_window_parameter):
7267 Accept any window as argument (Bug#12452).
7269 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7271 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7272 to ns_term_init to avoid memory leak.
7274 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7275 explicit retain/release.
7276 (ns_term_init): Only allow one display. Initialize outerpool and
7279 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7281 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7282 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7283 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7284 the Microsoft problem in a different way, by altering ../nt/config.nt.
7286 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7301 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7302 by lisp.h. This completes removal of setjmp.h inclusion
7303 erroneously announced in the previous commit. (Bug#12446)
7305 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7308 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7309 not defined as a macro. The latter happens on MS-Windows.
7312 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7314 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7315 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7316 Some instances of '#include <setjmp.h>' removed, if the
7317 only reason for the instance was because "lisp.h" was included.
7318 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7319 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7320 and _longjmp with the new symbols. Emacs already uses _setjmp if
7321 available, so this change affects only POSIXish hosts that have
7322 sigsetjmp but not _setjmp, such as some versions of Solaris and
7323 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7324 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7325 (png_load_body) [HAVE_PNG]:
7326 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7327 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7328 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7329 since PNG requires jmp_buf. This is the only exception to the
7330 general rule that we now use sys_setjmp and sys_longjmp.
7331 This exception is OK since this code does not change the signal
7332 mask or longjmp out of a signal handler.
7334 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7336 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7337 Include "syssignal.h", for 'main_thread'.
7339 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7341 Avoid out-of-range marker position (Bug#12426).
7342 * insdel.c (replace_range, replace_range_2):
7343 Adjust markers before overlays, as suggested by comments.
7344 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7345 Remove redundant check before calling offset_intervals.
7347 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7349 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7350 current buffer (Bug#12387).
7352 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7354 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7356 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7358 Use a more backwards-compatible timer format (Bug#12430).
7359 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7360 vector element, not from the 4th, since PSECS is now at the end.
7361 (Fcurrent_idle_time): Doc fix.
7363 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7365 Function to mark objects and remove killed buffers at once.
7366 * alloc.c (discard_killed_buffers): Rename to ...
7367 (mark_discard_killed buffers) ... new name. Add marking
7368 of remaining objects. Fix comment. Adjust users.
7369 (mark_object): Do not touch frame buffer lists here.
7370 * frame.c (delete_frame): Reset frame buffer lists here.
7372 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7374 Better workaround for GNOME bug when --enable-gcc-warnings.
7375 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7376 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7377 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7379 Simplify SIGIO usage (Bug#12408).
7380 The code that dealt with SIGIO was crufty and confusing, e.g., it
7381 played tricks like "#undef SIGIO" but these tricks were not used
7382 consistently. Simplify mostly by not #undeffing standard symbols,
7383 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7384 or not as we please) rather than "defined SIGIO" (standard symbol
7385 that we probably shouldn't #undef).
7386 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7387 Modules that need it can include it.
7388 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7389 * dispextern.h (ignore_sigio): New decl.
7390 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7391 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7392 * emacs.c (shut_down_emacs):
7393 * keyboard.c (kbd_buffer_store_event_hold):
7394 Use ignore_sigio rather than invoking 'signal' directly.
7395 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7397 (FIONREAD, SIGIO): Do not #undef.
7398 (tty_read_avail_input): Use #error rather than a syntax error.
7399 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7400 for I_PIPE, used by SETUP_SLAVE_PTY.
7401 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7402 * sysdep.c (croak): Remove; no longer needed. This bit of
7403 temporary code, with Fred N. Fish's comment that it's temporary,
7404 has been in Emacs since at least 1992!
7405 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7406 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7407 * syssignal.h (croak): Remove decl.
7408 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7409 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7410 now that we're termios-only.
7411 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7412 * term.c (dissociate_if_controlling_tty): Use #error rather than
7415 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7416 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7417 to work around GNOME bug 683906.
7418 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7419 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7420 This works around GCC bug 54561.
7422 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7424 More fixes for 'volatile' and setjmp/longjmp.
7425 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7426 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7427 (png_load_body) [HAVE_PNG]:
7428 (jpeg_load_body) [HAVE_JPEG]:
7429 New function, with most of the old parent function's body.
7430 (png_load) [HAVE_PNG]:
7431 (jpeg_load) [HAVE_JPEG]:
7432 Invoke the new function, to avoid longjmp munging our locals.
7433 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7434 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7435 longjmp is passed 2, as the C standard doesn't guarantee this.
7436 Instead, store the failure code into mgr->failure_code.
7438 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7440 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7441 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7442 (syms_of_keyboard): Remove support for unread-command-char.
7444 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7446 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7447 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7448 violation. (Bug#12426)
7450 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7452 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7454 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7456 * eval.c: Add `inhibit-debugger'.
7457 (Qinhibit_debugger): New symbol.
7458 (call_debugger): Bind it instead of Qdebug_on_error.
7459 (maybe_call_debugger): Test Vinhibit_debugger.
7460 (syms_of_eval): Define inhibit-debugger.
7461 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7462 (syms_of_xdisp): Remove inhibit-debug-on-message.
7464 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7466 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7467 If a nonvolatile local variable is written before a _longjmp to
7468 the frame containing the variable, and is read after the _longjmp,
7469 the value read is indeterminate. Some local variables of type
7470 'struct handler' and 'struct catchtag' are used in this way, so
7471 mark each of their slots as volatile if the slot can be set before
7472 _longjmp and read afterwards.
7473 * lisp.h (struct handler): var and chosen_clause are now volatile.
7474 (struct catchtag): val, next, and pdlcount are now volatile.
7476 * bidi.c (bidi_push_it, bidi_pop_it):
7477 * fns.c (copy_hash_table):
7478 * image.c (define_image_type):
7479 * keyboard.c (kbd_buffer_store_event_hold):
7480 * process.c (Fprocess_send_eof):
7481 * xfaces.c (x_create_gc) [HAVE_NS]:
7482 * xgselect.c (xg_select):
7483 Prefer assignment to memcpy when either will do.
7485 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7486 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7487 time an item is removed. No need to mark this function 'inline';
7488 the compiler knows better than we do.
7490 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7492 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7493 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7494 to change_frame_size (Bug#12388).
7495 (windowDidResize:): Pass YES to updateFrameSize.
7497 * nsterm.h: Add delay parameter to updateFrameSize.
7499 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7501 Discard killed buffers from deleted window and frame objects.
7502 This reduces an amount of references to killed buffers and
7503 helps GC to reclaim them faster.
7504 * alloc.c (discard_killed_buffers): New function.
7505 (mark_object): Use it for deleted windows and frames.
7506 (mark_object): If symbol's value is set up for a killed buffer
7507 or deleted frame, restore its global binding.
7508 * data.c (swap_in_global_binding): Add GC notice.
7509 (swap_in_symval_forwarding): Use convenient set_blv_where.
7510 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7511 * window.h: ... to here.
7513 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7515 Convenient macro to check whether the buffer is live.
7516 * buffer.h (BUFFER_LIVE_P): New macro.
7517 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7518 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7520 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7522 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7523 composition cases (Bug#12364).
7525 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7526 overhang of succeeding glyphs overlapping box cursor.
7528 * w32term.c (x_draw_glyph_string): Likewise.
7530 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7532 Simplify, document, and port floating-point (Bug#12381).
7533 The porting part of this patch fixes bugs on non-IEEE platforms
7534 with frexp, ldexp, logb.
7535 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7537 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7538 support, by removing commented-out code and briefly listing the
7539 C89 functions excluded. The commented-out stuff was confusing
7540 maintenance, e.g., we thought we needed cbrt but it was commented out.
7541 (logb): Remove decl; no longer needed.
7542 (isfinite): New macro, if not already supplied.
7543 (isnan): Don't replace any existing macro.
7544 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7545 are present on all C89 platforms.
7546 (Ffrexp): Do not special-case zero, as frexp does the right thing
7548 (Flogb): Do not use logb, as it doesn't have the desired meaning
7549 on hosts that use non-base-2 floating point. Instead, stick with
7550 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7551 frexp, to avoid getting an unspecified result.
7553 * xdisp.c (Qinhibit_debug_on_message): Now static.
7555 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7557 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7558 NSBezierPath (Bug#12131).
7560 2012-09-10 Chong Yidong <cyd@gnu.org>
7562 * fns.c (Fdelq, Fdelete): Doc fix.
7564 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7566 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7567 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7569 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7571 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7572 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7575 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7577 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7578 left fringe if the window has a left margin. This avoids leaving
7579 traces of the cursor because its leftmost pixel is not drawn over.
7581 * dispnew.c (update_window_line): When the left margin area of a
7582 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7583 that screen line. (Bug#12277)
7585 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7587 Assume C89 or later for math functions (Bug#12381).
7588 This simplifies the code, and makes it a bit smaller and faster,
7589 and (most important) makes it easier to clean up signal handling
7590 since we can stop worring about floating-point exceptions in
7591 library code. That was a problem before C89, but the problem
7592 went away many years ago on all practical Emacs targets.
7593 * data.c, image.c, lread.c, print.c:
7594 Don't include <math.h>; no longer needed.
7595 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7596 might be autoconfigured, as that never happens.
7598 * doprnt.c (DBL_MAX_10_EXP):
7599 * print.c (DBL_DIG):
7600 Remove. C89 or later always defines these.
7601 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7602 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7603 (arith_error, domain_error, domain_error2):
7604 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7605 no longer needed -- we simply return what C returns. All uses removed.
7606 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7608 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7609 Remove. All uses expanded, as these macros are no longer used
7610 more than once and are now more trouble than they're worth.
7611 (Ftan): Use tan, not sin / cos.
7612 (Flogb): Assume C89 frexp.
7613 (fmod_float): Assume C89 fmod.
7614 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7615 (init_floatfns): Remove. All uses removed.
7617 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7619 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7620 compositeToPoint for OSX < 10.6 (Bug#12390).
7622 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7624 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7625 This produces more-accurate results.
7627 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7629 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7630 changes (Bug#12088).
7632 2012-09-08 Chong Yidong <cyd@gnu.org>
7634 * syntax.c (Fstring_to_syntax): Doc fix.
7636 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7638 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7639 in the internal border.
7640 (x_set_window_size): Remove static variables and their usage.
7641 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7642 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7643 Remove fringe/internal border adjustment (Bug#11052).
7644 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7645 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7646 (ns_fix_rect_ibw): Remove.
7647 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7648 (ns_dumpglyphs_box_or_relief): Ditto.
7649 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7651 (ns_dumpglyphs_image): Ditto.
7652 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7654 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7655 their usage. Add fringe_extended_p and its use as in other terms.
7656 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7657 scroll bar was removed.
7658 (updateFrameSize): New function.
7659 (windowDidResize): Move code to updateFrameSize and call it.
7661 * nsterm.h (EmacsView): Add updateFrameSize.
7663 2012-09-07 Chong Yidong <cyd@gnu.org>
7665 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7667 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7669 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7671 More signal-handler cleanup (Bug#12327).
7672 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7673 Problem introduced when merging patches. Noted by Eli Zaretskii in
7674 <http://bugs.gnu.org/12327#67>.
7675 * floatfns.c: Comment fix.
7676 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7677 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7678 and anyway the declaration is harmless even if SIGDANGER is not defined.
7679 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7680 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7681 source files not surprisingly expected syssignal.h to define, or
7682 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7683 Include <sys/ioctl.h>, for FIONREAD.
7684 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7685 This eliminates a problem whereby other files mysteriously had
7686 to include "syssignal.h" before including "systty.h" if they
7687 wanted to use "#ifdef SIGIO".
7689 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7691 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7693 * w32.c (sigemptyset): Empty the set.
7694 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7696 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7698 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7700 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7701 (mark_object): Likewise for frame objects.
7703 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7705 * syssignal.h (handle_on_main_thread): Always declare,
7706 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7707 This ports to platforms without HAVE_PTHREAD.
7709 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7711 Signal-handler cleanup (Bug#12327).
7712 Emacs's signal handlers were written in the old 4.2BSD style with
7713 sigblock and sigmask and so forth, and this led to some
7714 inefficiencies and confusion. Rewrite these to use
7715 pthread_sigmask etc. without copying signal sets around. Also,
7716 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7717 'signal', and instead use functions that do not attempt to take
7718 over the system name space. This patch causes Emacs's text
7719 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7720 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7721 Do not include <signal.h> or "syssignal.h", as these
7722 modules do not use signals.
7723 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7724 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7725 Do not include <signal.h>, as "syssignal.h" does that for us now.
7726 * atimer.c (sigmask_atimers): New function.
7727 (block_atimers, unblock_atimers): New functions,
7728 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7730 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7731 no longer needed here.
7732 * emacs.c (main): Inspect existing signal handler with sigaction,
7733 so that there's no need to block and unblock SIGHUP.
7734 * sysdep.c (struct save_signal): New member 'action', replacing
7735 old member 'handler'.
7736 (save_signal_handlers, restore_signal_handlers):
7737 Use sigaction instead of 'signal' to save and restore.
7738 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7739 New function. All users of 'signal' modified to use set_sighandler
7740 if they're writeonly, and to use sys_signal if they're read+write.
7741 (emacs_sigaction_init, forwarded_signal): New functions.
7742 (sys_signal): Remove. All uses replaced by calls to sigaction
7743 and emacs_sigaction_init, or by direct calls to 'signal'.
7744 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7745 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7746 all uses replaced by pthread_sigmask etc. calls.
7747 * syssignal.h: Include <signal.h>.
7748 (emacs_sigaction_init, forwarded_signal): New decls.
7749 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7750 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7751 (sigmask, sys_sigmask): Remove; no longer needed.
7752 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7753 (sigblock, sigunblock, sigfree):
7754 (sigsetmask) [!defined sigsetmask]:
7755 Remove. All uses replaced by pthread_sigmask.
7756 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7757 no longer need to be replaced, and its typical old uses
7758 are now done via emacs_sigaction_init and sigaction.
7759 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7760 (sys_sigdel): Remove; unused.
7761 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7763 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7765 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7766 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7768 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7770 Explicitly mark buffer_defaults and buffer_local_symbols.
7771 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7772 mark_local_symbols here.
7773 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7774 since special buffers aren't marked here any more.
7775 (allocate_buffer): Chain new buffer with all_buffers here...
7776 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7778 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7779 (syms_of_buffer): Remove staticpro of the above.
7780 (init_buffer_once): Set names for buffer_defaults and
7781 buffer_local_symbols.
7783 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7785 Use bool for booleans in font-related modules.
7786 * font.c (font_intern_prop, font_style_to_value)
7787 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)

7799 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7800 Use bool for booleans.
7801 * font.h: Adjust to above API changes.
7802 (struct font, struct font_driver, struct font_driver_list):
7803 Use bool for booleans.
7804 (struct font): Remove useless member encoding_type.
7806 * fontset.c, xftfont.c: Omit unnecessary static decls.
7808 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7810 * alloc.c (mark_object): Revert window marking code
7811 since it's unsafe for the Fset_window_configuration.
7813 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7815 Fix race conditions with signal handlers and errno (Bug#12327).
7816 Be more systematic about preserving errno whenever a signal
7817 handler returns, even if it's not in the main thread. Do this by
7818 renaming signal handlers to distinguish between signal delivery
7819 and signal handling. All uses changed.
7820 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7821 * data.c (deliver_arith_signal): Rename from arith_error.
7822 * dispnew.c (deliver_window_change_signal): Rename from
7823 window_change_signal.
7824 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7825 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7826 * keyboard.c (deliver_input_available_signal): Rename from
7827 input_available_signal.
7828 (deliver_user_signal): Rename from handle_user_signal.
7829 (deliver_interrupt_signal): Rename from interrupt_signal.
7830 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7831 (deliver_child_signal): Rename from sigchld_handler.

7833 * data.c (handle_arith_signal):
7834 * dispnew.c (handle_window_change_signal):
7835 * emacs.c (handle_fatal_signal, handle_danger_signal):
7836 * keyboard.c (handle_input_available_signal):
7837 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7838 * process.c (handle_pipe_signal, handle_child_signal):
7839 New functions, with the actual signal-handling code taken from the
7840 original respective signal handlers, sans the sporadic attempts to
7841 preserve errno, since that's now done by handle_on_main_thread.
7842 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7843 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7844 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7846 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7847 Move initialization of main_thread to sysdep.c's init_signals.
7848 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7849 our usage, and simplifies the mainline code.
7850 (record_child_status_change): New static function, as a helper
7851 for handle_child_signal, and with most of the old child handler's
7853 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7854 (handle_child_signal): Use the above.
7855 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7856 Moved here from emacs.c.
7857 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7858 code moved here from emacs.c's main function.
7859 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7860 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7861 This lets callers save and restore errno properly.
7863 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7865 Remove redundant or unused things here and there.
7866 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7867 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7868 * editfns.c (Fcompare_buffer_substrings): Likewise.
7869 * frame.h (struct terminal, struct font_driver_list):
7870 Remove redundant declarations.
7871 * window.h (Qleft, Qright): Likewise.
7873 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7875 Do not mark objects from deleted buffers, windows and frames.
7876 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7877 (mark_object): Likewise for windows and frames.
7879 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7881 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7882 buffer_defaults and buffer_local_symbols as valid objects.
7883 Return special value to denote them.
7885 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7887 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.

7902 * lisp.h (struct Lisp_Hash_Table.cmpfn):

7904 Use bool for booleans.
7905 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7906 (Fdefault_file_modes): Now mode_t, not int, for modes.
7907 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7908 (internal_delete_file): Now returns void, not a (boolean) int,
7909 since nobody was looking at the return value.
7910 * lisp.h, window.h: Adjust to above API changes.
7912 * xdisp.c (set_message): Simplify and reindent last change.
7914 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7916 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7918 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7920 * eval.c (call_debugger): Make the function non-static so that we
7921 can call it from set_message.
7923 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7924 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7926 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7928 Give more-useful info on a fatal error (Bug#12328).
7929 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7930 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7931 of doing the work ourselves.
7932 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7933 do most of the work.
7934 (fatal_error_backtrace): New function, taken from the guts
7935 of the old fatal_error_signal, but with a new option to output
7937 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7938 info about the signal than just its number.
7939 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7940 * sysdep.c: Include <execinfo.h>
7941 (emacs_backtrace): New function, taken partly from the previous
7942 code of the 'die' function.
7943 (emacs_abort): Call fatal_error_backtrace rather than abort.
7945 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7947 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7948 eager (load-time) macro-expansion.
7949 * lisp.mk (lisp): Add macroexp.
7951 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7953 Simplify redefinition of 'abort' (Bug#12316).
7954 Do not try to redefine the 'abort' function. Instead, redo
7955 the code so that it calls 'emacs_abort' rather than 'abort'.
7956 This removes the need for the NO_ABORT configure-time macro
7957 and makes it easier to change the abort code to do a backtrace.
7958 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7959 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7960 Remove; sysdep.c's emacs_abort now takes its place.
7961 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7962 'abort' changed to use 'emacs_abort'.
7963 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7964 (abort) [!defined abort]: Rename to ...
7965 (emacs_abort): ... new name.
7966 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7967 the place of the old 'abort' in emacs.c.
7968 * w32.c, w32fns.c (abort): Do not #undef.
7969 * w32.c (emacs_abort): Rename from w32_abort.
7971 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7973 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7974 offsets[j].dv, since the y axis of the screen coordinates points
7975 down, while the y axis of the font definition coordinates points
7976 up. This fixes display of Arabic diacritics such as KASRA and
7977 KASRATAN. (Bug#11860)
7979 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7981 Be more systematic about _setjmp vs setjmp.
7982 * alloc.c (test_setjmp, mark_stack):
7983 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7984 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7985 (png_load, my_error_exit, jpeg_load):
7986 * process.c (send_process_trap, send_process):
7987 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7988 The underscored versions are up to 30x faster on some hosts.
7989 Formerly, the code used setjmp+longjmp sometimes and
7990 _setjmp+_longjmp at other times, with no particular reason to
7991 prefer setjmp+longjmp.
7993 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7995 Fix minor problem found by static checking.
7996 * buffer.c (Fdelete_all_overlays): Return nil.
7998 2012-09-03 Martin Rudalics <rudalics@gmx.at>
8000 * buffer.c (Fdelete_all_overlays): New function.
8002 2012-09-03 Chong Yidong <cyd@gnu.org>
8004 * gtkutil.c: Add extern decl for Qxft.
8006 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
8008 * emacs.c, eval.c: Use bool for boolean.
8009 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
8010 (malloc_using_checking) [DOUG_LEA_MALLOC]:
8011 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

8016 (maybe_call_debugger, Fbacktrace):
8017 * process.c (read_process_output, exec_sentinel):
8018 Use bool for booleans.
8019 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
8020 All callers changed.
8021 * eval.c (interactive_p): Omit always-true boolean argument
8022 EXCLUDE_SUBRS_P. All callers changed.
8023 * dispextern.h, lisp.h: Reflect above API changes.
8024 * firstfile.c (dummy): Use the address of 'main', whose signature
8025 won't change, instead of the address of 'initialize', whose
8026 signature just changed from int to bool.
8027 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
8028 * msdos.c (fatal_error_in_progress): ... from here.
8029 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
8031 (redisplay_internal, unwind_redisplay): Simply clear
8032 REDISPLAYING_P when unwinding, instead of saving its previous,
8033 always-false value and then restoring it.
8035 Clean up some extern decls.
8036 Mostly, this hoists extern decls out of .c files and into .h files.
8037 That way, we're more likely to catch errors if the interfaces change.
8038 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
8039 declare xg_mark_data.
8040 * dispextern.h (x_frame_parm_handlers):
8042 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
8043 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

8058 * xfont.c (x_clear_errors):
8059 * xterm.c (x_frame_parm_handlers):
8060 Remove now-redundant extern decls.
8061 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
8062 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
8064 * xfaces.c: Remove unnecessary static decls.
8065 * xterm.c (updating_frame): Remove decl of nonexistent object.
8067 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
8068 when building globals.h, as the objects that are not built on
8069 this host are not needed to compile C files on this host.
8071 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
8073 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

8111 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
8113 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

8119 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
8121 2012-09-01 Eli Zaretskii <eliz@gnu.org>
8123 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
8124 more than one grapheme cluster passed to the shaper: compute the
8125 offset adjustment values separately for each cluster. (Bug#11860)
8127 * image.c: Restore mistakenly removed inclusion of w32.h. Without
8128 it, GCC doesn't see prototypes of w32_delayed_load, and complains
8129 about implicit conversions from integer to pointer.
8131 2012-09-01 Daniel Colascione <dancol@dancol.org>
8133 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
8134 system used too early.
8136 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
8138 Better seed support for (random).
8139 * emacs.c (main): Call init_random.
8140 * fns.c (Frandom): Set the seed from a string argument, if given.
8141 Remove long-obsolete Gentzel cruft.

8143 (init_random): New function.
8145 2012-09-01 Daniel Colascione <dancol@dancol.org>
8147 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
8148 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
8149 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,

8151 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
8152 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
8153 all of which have been moved to common code.
8155 * xfaces.c: Include TERM_HEADER instead of listing all possible
8156 window-system headers.
8158 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
8161 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
8162 directly accessing frame internals.
8164 * w32font.h: Include font.h. Define syms_of_w32font and
8167 * process.c: Include TERM_HEADER instead of listing all possible
8168 window-system headers.
8170 * nsterm.h: Remove declarations now in frame.h.
8171 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
8173 * menu.c: Include TERM_HEADER instead of listing all possible
8174 window-system headers.
8176 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
8179 * keyboard.c: Include TERM_HEADER instead of listing all possible
8180 window-system headers.
8182 * image.c: Include TERM_HEADER instead of listing all possible
8183 window-system headers. Declare Vlibrary_cache when compiling for
8186 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
8187 window system declarations.
8189 * frame.h: Move common functions here: set_frame_menubar,
8190 x_set_window_size, x_sync, x_get_focus_frame,
8191 x_set_mouse_position, x_set_mouse_pixel_position,
8192 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

8213 the current window system; include in list of objects to link into
8216 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8218 Remove mark_ttys function and fix tty_display_info initialization.
8219 * lisp.h (mark_ttys): Remove prototype.
8220 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8221 to mark_ttys because all possible values of 'top_frame' slot are
8222 the frames which are reachable from Vframe_list.
8223 * term.c (mark_ttys): Remove.
8224 (init_tty): Safely initialize 'top_frame' slot with Qnil.
8226 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8228 Change struct frame bitfields from unsigned char to unsigned.
8229 * frame.h (struct frame): Change type of 'display_preempted',
8230 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
8231 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
8232 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
8233 bitfields from unsigned char to unsigned.
8235 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8237 Remove unused member of struct x_output and struct w32_output.
8238 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
8239 * w32term.h (struct w32_output): Likewise.
8241 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
8243 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
8244 does not become zero (Bug#12234).
8246 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
8248 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
8249 for GCC 4.7.1 x86-64.
8251 2012-08-30 Glenn Morris <rgm@gnu.org>
8253 * lread.c (init_lread): For out-of-tree builds, only add the
8254 source directory's site-lisp dir to the load-path if it exists,
8255 consistent with in-tree builds. (Bug#12302)
8257 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
8259 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
8260 button_values to NULL. Call setStykeMask so dialogs get a close button.
8261 (windowShouldClose:): Set window_closed.
8262 (dealloc): New member, free button_values.
8263 (process_dialog:): Make member function. Remove window argument,
8264 replace window with self. Count buttons and allocate and store values

8269 (addSplit): Remove return self, declare return value as void.
8270 (clicked:): Remove return self, declare return value as void.
8271 Set dialog_return to button_values[seltag]. Code formatting change.
8272 (initFromContents:isQuestion:): Adjust call to process_dialog.
8273 Code formatting change.
8274 (timeout_handler:): Set timer_fired to YES.
8275 (runDialogAt:): Set timer_fired to NO.
8276 Handle click on close button as quit.
8278 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8279 Add window_closed and button_values. Add void as return value for
8280 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8281 Add process_dialog as new member.
8283 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8285 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
8286 is not one of the heaps we manage. (Bug#12242)
8288 2012-08-28 Glenn Morris <rgm@gnu.org>
8290 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
8292 2012-08-28 Martin Rudalics <rudalics@gmx.at>
8294 * window.c (Fset_window_configuration): Remove handling of
8295 auto-buffer-name window parameter. Install revision of reverted
8298 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
8300 Do not allow to set major mode for a dead buffer.
8301 * buffer.c (Fset_buffer_major_mode): Signal an error
8302 if the buffer is dead.
8303 (Fother_buffer, other_buffer_safely): Remove redundant
8306 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
8308 Always use set_buffer_if_live to restore original buffer at unwind.
8309 * buffer.h (record_unwind_current_buffer): New function.
8310 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
8311 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
8312 * undo.c, window.c: Adjust users.
8313 * buffer.c (set_buffer_if_live): Fix comment.
8315 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
8317 Fix usage of set_buffer_internal.
8318 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
8319 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
8320 * coding.c (decode_coding): Omit redundant test.
8321 * fileio.c (decide_coding_unwind): Likewise.
8322 * fns.c (secure_hash): Likewise.
8323 * insdel.c (modify_region): Likewise.
8324 * keyboard.c (command_loop_1): Likewise.
8325 * print.c (PRINTFINISH): Likewise.
8326 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
8328 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

8348 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
8349 and remove last int (actually boolean) argument, which was always 0.
8350 All callers changed.
8351 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
8352 * dispextern.h (struct composition_it): Use bool for boolean.
8353 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
8354 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
8355 * dired.c (file_name_completion):
8356 Use bool for boolean. (This was missed in an earlier change.)
8358 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8360 * window.c (Fset_window_configuration): Revert first part of
8363 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
8365 * nsterm.h (NSPanel): New class variable dialog_return.
8367 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
8368 Initialize dialog_return.
8369 (windowShouldClose:): Use stop instead of stopModalWithCode.
8370 (clicked:): Ditto, and also set dialog_return (Bug#12258).
8371 (timeout_handler:): Use stop instead of abortModal. Send a dummy
8373 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

8391 Omit int (actually boolean) argument. It wasn't being used.
8393 * composite.h, lisp.h: Reflect above API changes.

8417 * fileio.c (Finsert_file_contents):
8418 Use bool for booleans.
8419 * coding.h, lisp.h: Reflect above API changes.
8420 * coding.c: Remove unnecessary static function decls.
8421 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8422 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8423 not a boolean 'int', since callers never look at the return value.
8424 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8425 * coding.h (decoding_buffer_size, encoding_buffer_size)
8426 (emacs_mule_string_char): Remove unused extern decls.
8427 (struct iso_2022_spec, struct coding_system):
8428 Use 'unsigned int : 1' for boolean fields, since there's more than one.
8429 (struct emacs_mule_spec): Remove unused field 'full_support'.
8430 All initializations removed.
8431 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
8433 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8435 Fix spare memory change (Bug#12286).
8436 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8437 (valid_lisp_object_p): Likewise.
8439 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8441 * window.c (Fset_window_configuration): Record any window's old
8442 buffer if it's replaced (see Bug#8789). If the new current
8443 buffer doesn't appear in the selected window, go to its old
8446 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8448 Special MEM_TYPE_SPARE to denote reserved memory.
8449 * alloc.c (enum mem_type): New memory type.
8450 (refill_memory_reserve): Use new type for spare memory.
8451 This prevents live_cons_p and live_string_p from incorrect
8452 detection of uninitialized objects from spare memory as live.
8454 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8457 * Makefile.in (.PHONY): versioclean -> versionclean.
8459 Remove unused external symbols.
8460 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8461 * window.c (Qwindow_valid_p, decode_valid_window):
8462 Now static, not extern.
8463 * data.c (Qinterval): Remove; unused.
8464 (syms_of_data): Do not define 'interval'.
8465 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8466 * window.h (decode_valid_window):
8469 * character.c, charset.c, chartab.c: Use bool for booleans.

8480 (map_sub_char_table):
8481 Use bool for boolean.
8482 * character.c (str_to_unibyte): Omit last boolean argument; it was
8483 always 0. All callers changed.
8484 * character.h, charset.h: Adjust to match previous changes.
8485 * character.h (char_printable_p): Remove decl of nonexistent function.
8486 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8487 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8488 are all boolean, so make them single-bit bitfields.
8490 * lisp.h (ASET): Remove attempt to detect side effects.
8491 It was meant to be temporary and it often doesn't work,
8492 because when IDX has side effects the behavior of IDX==IDX
8493 is undefined. See Stefan Monnier in
8494 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8496 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8498 * lisp.h (functionp): New function (extracted from Ffunctionp).
8499 (FUNCTIONP): Use it.
8500 * eval.c (Ffunctionp): Use it.
8502 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8504 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8505 as that's faster and simpler than static storage. Don't bother
8506 with the g_main_context_query overhead if g_main_context_pending
8507 says no events are pending.
8508 (gfds, gfds_size): Remove these static vars.
8509 (xgselect_initialize): Remove; no longer needed.
8510 All uses and decls removed.
8512 * emacs.c (fatal_error_signal_hook): Remove.
8513 All uses removed. This leftover from old code was always 0.
8515 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8516 * casefiddle.c (casify_object, casify_region):
8517 * casetab.c (set_case_table):
8518 * category.c, category.h (word_boundary_p):
8519 * category.h (CHAR_HAS_CATEGORY):
8520 Use bool for booleans, instead of int.
8522 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8524 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8526 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8528 On assertion failure, print backtrace if available.
8529 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8530 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8531 * Makefile.in (LIB_EXECINFO): New macro.
8534 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8535 * bytecode.c (exec_byte_code):
8536 * callint.c (check_mark, Fcall_interactively):
8537 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8538 (getenv_internal, sync_process_alive, call_process_exited):
8539 * lisp.h (USE_SAFE_ALLOCA):
8540 Use bool for booleans, instead of int.
8541 * lisp.h, process.h: Adjust prototypes to match above changes.
8542 * callint.c (Fcall_interactively): Don't assume the mark's
8543 offset fits in 'int'.
8545 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8547 * buffer.c, buffer.h: Use bool for boolean.
8548 * buffer.c (reset_buffer_local_variables)

8554 (mmap_enlarge, mmap_set_vars):
8555 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8556 Use bool for booleans, instead of int.
8557 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8558 since the 1-or-0 return value is always ignored anyway.
8559 (mmap_initialized_p):
8560 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8561 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8563 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8565 * bidi.c: Use bool for boolean.
8566 This is a bit more readable, and makes the text segment of bidi.o
8567 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8568 Presumably it's faster too.
8569 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

8574 (bidi_explicit_dir_char, bidi_level_of_next_char)
8575 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8576 Use bool for booleans, instead of int.
8577 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8578 (bidi_unshelve_cache): Adjust decls to match code.
8580 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8582 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8585 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8587 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8588 * atimer.h: Include <stdbool.h>.
8590 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8592 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8593 compile time tests instead of run time tests on systems that do
8595 (FRAME_MAC_P): Remove leftover from deleted code.
8596 * frame.c (syms_of_frame): Remove leftover from deleted code.
8598 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8600 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8602 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8604 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8605 Otherwise, the compiler complains about (A?B:C) where B is void
8606 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8607 (fontset_add): Return void, for FONTSET_ADD.
8609 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8611 * alloc.c: Use bool for booleans.
8612 (gc_in_progress, abort_on_gc)
8613 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8614 (dont_register_blocks) [GC_MALLOC_CHECK]:
8615 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

8617 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8618 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8619 (mark_stack, valid_pointer_p, make_pure_string)
8620 (Fgarbage_collect, survives_gc_p, gc_sweep):
8621 Use bool for booleans, instead of int.
8622 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8623 Remove unused local.
8624 * alloc.c (PURE_POINTER_P):
8625 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8626 * editfns.c (Fformat):
8627 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8629 * fns.c (sweep_weak_table):
8630 * lisp.h (suppress_checking, push_message, survives_gc_p)
8631 (make_pure_string, gc_in_progress, abort_on_gc):
8632 * lread.c (readchar, read1):
8633 * print.c (Fprin1_to_string):
8634 * xdisp.c (push_message):
8635 Use bool for booleans affected directly or indirectly by
8638 Make recently-introduced setters macros.
8639 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8640 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8641 (set_fontset_default, set_fontset_fallback): Rename from their
8642 upper-case counterparts, and make them functions rather than macros.
8643 This is more consistent with the other recently-introduced setters.
8644 These don't need to be inline, since they're local.
8646 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8648 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8649 the loop (Bug#12247).
8651 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8653 * lisp.h (vcopy): Use memcpy rather than our own loop.
8654 This fixes a performance regression introduced by the recent
8655 addition of vcopy. This means 'vcopy' will need to be modified
8656 for a copying collector, but that's OK. Also, tighten the
8657 checking in the assertion.
8659 2012-08-21 Eli Zaretskii <eliz@gnu.org>

8753 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8755 Rely on <config.h> + <unistd.h> to declare 'environ',
8756 as gnulib does this if the system doesn't.
8757 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

9626 2012-08-04 Eli Zaretskii <eliz@gnu.org>
9628 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
9629 * w32.c (init_environment): Change the default values of many
9630 environment variables in dflt_envvars[] to NULL, to avoid pushing
9631 them into environment when they were not already defined.
9632 Remove the code that deletes site-lisp subdirectories from the default
9633 value of EMACSLOADPATH, as it is no longer needed.
9634 (check_windows_init_file): Now external, not static.
9635 Use Vload_path as is, without adding anything, as this function is now
9636 called when Vload_path is already set up.
9638 * w32.h (check_windows_init_file): Add prototype.
9640 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
9641 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
9642 compatibility with Posix platforms.
9643 (main): Move the call to check_windows_init_file to here from
9645 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
9646 any, in the DEFALT argument into the root of the Emacs build or
9647 installation tree, as appropriate.
9649 * callproc.c (init_callproc_1): Call decode_env_path instead of
9650 doing its equivalent by hand.
9651 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
9652 the code that sets Vexec_path run on MS-Windows.
9654 * lread.c (init_lread): Add comments to #ifdef's.
9656 * msdos.c (dos_set_window_size, IT_update_begin)

9664 Now constants, not macros.
9666 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
9668 Remove unnecessary casts involving pointers.
9669 These casts are no longer needed now that we assume C89 or later,
9670 since they involve casting to or from void *.
9671 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
9672 (make_pure_float, make_pure_vector):
9673 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

9682 (x_get_window_property, x_get_window_property_as_lisp_data):
9683 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9684 Remove unnecessary pointer casts.
9685 * alloc.c (record_xmalloc): New function.
9686 * lisp.h (record_xmalloc): New decl.
9687 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9688 more like a function. This is because the pointer cast is not
9689 needed. All uses changed.
9690 * print.c (print_string, print_error_message): Avoid length recalc.
9692 Improve fix for macroexp crash with debugging (Bug#12118).
9693 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9694 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9695 not supposed to be invoked from the garbage collector.
9696 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9697 (gc_aset): New function, which is like ASET but can be
9698 used in the garbage collector.
9699 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

9711 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
9712 (map_w32_filename): Improve commentary. Simplify switch.
9713 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
9714 headers (most versions of MinGW w32api don't).
9715 (get_security_info, create_symbolic_link)
9716 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
9718 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
9719 in the argument file name.

9722 (sys_rename): Diagnose renaming of a symlink when the user doesn't
9723 have the required privileges.
9724 (get_file_security_desc_by_name): Rename from
9725 get_file_security_desc.
9726 (stat_worker): New function, with most of the guts of 'stat', and
9727 with addition of handling of symlinks and support for 'lstat'.
9728 If possible, get file's attributes and security information by
9729 handle, not by name. Produce S_IFLNK bit for symlinks, when
9730 called from 'lstat'.
9731 (stat, lstat): New functions, call 'stat_worker'.
9732 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9733 symlinks when the underlying filesystem supports them.
9735 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9737 Fix macroexp crash on Windows with debugging (Bug#12118).
9738 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9739 checking subscripts; problem introduced with the recent
9740 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9741 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9742 since it's used in non-static inline functions now.
9744 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9745 Don't assume buffer size fits in 'int'. Remove unused local.
9747 Use C99-style 'extern inline' if available.

9762 * category.c (CATEGORY_INLINE):
9763 * character.c (CHARACTER_INLINE):
9764 * charset.c (CHARSET_INLINE):
9765 * composite.c (COMPOSITE_INLINE):
9766 * dispnew.c (DISPEXTERN_INLINE):
9767 * sysdep.c (SYSTIME_INLINE):
9768 Define to EXTERN_INLINE, so that the corresponding functions
9769 are compiled into code.
9770 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9771 (INLINE_HEADER_END): New macros.
9772 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9792 hard-coding the path separator.
9794 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9796 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9797 This how ASET and AREF are supposed to work, and makes
9798 it easier to think about future improvements. See
9799 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9800 * charset.h (set_charset_attr): New function.

10009 keyboard_codepage and now external. All users changed.
10011 * w32term.h: Add declaration of w32_keyboard_codepage.
10013 * w32inevt.c (w32_kbd_patch_key): Accept an additional argument --

10101 * lisp.h (LISP_INT_TAG, LISP_INT1_TAG, LISP_STRING_TAG): Remove.
10102 These macros are confusing and no longer need to be defined, as
10103 the enum values now suffice. All uses replaced with definiens.

10177 * w32inevt.c: Include w32inevt.h.
10178 (w32_read_console_input): New inline function, calls either
10179 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
10180 w32_console_unicode_input.
10181 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
10182 (w32_kbd_patch_key, key_event): Use the codepage returned by

10215 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10216 enumeration constants, as PURE and HEAP are too general, and clash
10217 with other headers and sources, such as gmalloc.c and the
10218 MS-Windows system headers. All users changed.
10220 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10222 Revert last save_excursion_save and save_excursion_restore changes.
10223 * alloc.c, editfns.c, marker.c, lisp.h: Revert.
10224 Lots of crashes reported by Chong Yidong <cyd@gnu.org>.
10226 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10228 Fix recently-introduced typos in Windows port.
10229 Reported by Martin Rudalics <rudalics@gmx.at>.

10231 * w32fns.c (syms_of_w32fns): Add missing parenthesis.
10233 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10235 Improve GDB symbol export (Bug#12036).
10236 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10237 arms of an 'if', not using conditional expressions; otherwise GDB
10238 complains about the types in the unevaluated arm when the argument
10239 is an integer literal.
10240 (xgetint): Simplify expression.
10241 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10242 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10243 Zaretskii in <http://bugs.gnu.org/12036#13>.
10244 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10245 needed now that we have gdb_make_enums_visible.
10246 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10247 (enum enum_USE_LSB_TAG):
10248 New enum types, packaging up enums that need to be exported to GDB.
10250 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10252 Utility function to make a list from specified amount of objects.
10253 * lisp.h (enum constype): New datatype.
10254 (listn): New prototype.
10255 * alloc.c (listn): New function.
10256 (Fmemory_use_count, syms_of_alloc): Use it.
10257 * buffer.c (syms_of_buffer): Likewise.
10258 * callint.c (syms_of_callint): Likewise.

10267 * xfns.c (syms_of_xfns): Likewise.
10269 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10271 Fast save_excursion_save and save_excursion_restore.
10272 * lisp.h (struct Lisp_Excursion): New data type.
10273 (PVEC_EXCURSION): New pseudovector type.
10274 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10275 to deal with it. Adjust comments.
10276 (init_marker, attach_marker): New prototype.
10277 (unchain_marker): Adjust prototype.
10278 * marker.c (attach_marker): Change to global.
10279 (init_marker): New function.
10280 * alloc.c (Fmake_marker, build_marker): Use it.
10281 (build_marker): More easserts.
10282 (mark_object): Handle struct Lisp_Excursion.
10283 * editfns.c (save_excursion_save, save_excursion_restore):

10289 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10290 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10291 emacs.c, as this is a more-suitable home. Had this been done earlier
10292 the fix for 12036 would have avoided some of the problems noted in
10293 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10294 would have been more obvious.
10295 * emacs.c: Do not include <verify.h>; no longer needed.
10296 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
10297 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
10298 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10299 Remove; now done in lisp.h.
10300 * lisp.h (PUBLISH_TO_GDB): New macro.
10301 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
10302 (DATA_SEG_BITS): Use it.
10303 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10304 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10305 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10306 not be usable in #if. This simplifies things.
10308 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10310 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10312 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10314 Simplify export of symbols to GDB (Bug#12036).
10315 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10316 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10317 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10318 Adjust to changes in lisp.h and emacs.c, by using
10319 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10320 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10321 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10322 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10323 instead of gdb_valbits.
10324 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10325 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10326 instead of gdb_array_mark_flag.
10327 (xboolvector): Get size from $->size, not $->header.size.
10328 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10329 (xreload, hook-run, hookpost-run): Remove.
10330 * emacs.c: Include <verify.h>.
10331 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10332 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10334 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10335 (gdb_USE_LSB_TAG): New enum constants.
10336 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10337 Also define these as enum constants, so they're visible to GDB.
10338 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10339 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10340 as constants, so they're visible to GDB.
10341 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10342 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10343 Now enum constants, not macros, so they're visible to GDB.
10344 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10345 more convenient now. All uses changed.
10346 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10347 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10349 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
10351 Explicitly free restriction data that are not needed anymore.
10352 * editfns.c (save_restriction_restore): Free restriction data.
10354 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
10356 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10357 add argument, tune behavior, and adjust all callers.
10359 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10361 Use typedef for EMACS_INT, EMACS_UINT.
10362 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10363 than macros. This simplifies debugging in the usual case, since
10364 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10365 and it allows expressions involving EMACS_INT casts.
10366 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10368 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10370 * nsterm.m (ns_read_socket): Return early if there is a modal
10371 window (Bug#12043).
10373 2012-07-25 Martin Rudalics <rudalics@gmx.at>
10375 * frame.c (Fredirect_frame_focus): In doc-string don't mention
10376 that FOCUS-FRAME can be omitted.
10378 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
10380 Adjust buffer text indirection counters at the end of Fkill_buffer.
10381 * buffer.c (Fkill_buffer): Adjust indirection counters when the
10382 buffer is definitely dead. This should really fix an issue reported
10383 by Christoph Scholtes again. (Bug#12007).
10384 (init_buffer_once): Initialize indirection counters of
10385 buffer_defaults and buffer_local_symbols (for sanity and safety).
10387 2012-07-24 Eli Zaretskii <eliz@gnu.org>
10389 * xdisp.c (init_iterator): Don't compute dimensions of truncation
10390 and continuation glyphs on tooltip frames, leave them at zero.
10391 Avoids continued lines in tooltips. (Bug#11832)
10393 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
10395 Simplify copy_overlay.

11223 (menu_separator_name_p):
11224 * nsmenu.m (ns_update_menubar):
11225 Prefer memcmp to strncmp when either will do.
11226 * nsterm.m: Include <ftoastr.h>.
11228 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11229 Prefer snprintf to strncpy.
11230 * nsterm.m (ns_term_init):
11231 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11232 * nsterm.m (ns_term_init):
11233 Avoid the need for strncpy, by using build_string or
11234 make_unibyte_string directly. Use dtoastr, not snprintf.
11235 * process.c (Fmake_network_process): Diagnose service names that
11236 are too long, rather than silently truncating them or creating

11267 Optimize pure C strings initialization.
11268 * lisp.h (make_pure_string): Fix prototype.
11269 (build_pure_c_string): New function, defined as static inline. This
11270 provides a better opportunity to optimize away calls to strlen when
11271 the function is called with compile-time constant argument.
11272 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11273 argument, adjust users accordingly. Use build_pure_c_string where
11275 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
11276 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11277 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
11279 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
11281 Avoid calls to strlen in miscellaneous functions.
11282 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
11283 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
11284 * lread.c (openp): Likewise.
11286 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
11288 Avoid calls to strlen in path processing functions.
11289 * fileio.c (file_name_as_directory): Add comment. Change to add
11290 srclen argument and return the length of result. Adjust users
11292 (directory_file_name): Fix comment. Change to add srclen argument,
11293 swap 1st and 2nd arguments to obey the common convention.
11294 Adjust users accordingly.
11295 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
11297 2012-07-10 Glenn Morris <rgm@gnu.org>

11304 * s/gnu.h (DATA_START): Move definitions to configure.
11306 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
11307 We include usg5-4-common.h, which defines them both.
11309 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11310 O_RDONLY already includes it).
11312 Stop ns builds setting the EMACSLOADPATH environment variable.
11313 * nsterm.m (ns_load_path): Rename from ns_init_paths.
11314 Now it does not set EMACSLOADPATH, just returns the load-path string.
11315 * nsterm.h: Update accordingly.
11316 * lread.c [HAVE_NS]: Include nsterm.h.
11317 (init_lread) [HAVE_NS]: Use ns_load_path.
11318 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
11320 2012-07-09 Glenn Morris <rgm@gnu.org>
11322 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
11323 since the included bsd-common.h does so.
11325 Stop ns builds setting the EMACSPATH environment variable.
11326 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
11327 (ns_init_paths): Do not set EMACSPATH.
11328 * nsterm.h (ns_exec_path): Add it.
11329 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
11332 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
11334 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
11336 * process.c (wait_reading_process_output): 'waitchannels' was unset
11337 when read_kbd || !NILP (wait_for_cell); fix this.
11339 Add GCC-style 'const' attribute to functions that can use it.
11340 * character.h (char_resolve_modifier_mask):
11341 * keyboard.h (make_ctrl_char):
11342 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
11343 (init_character_once, next_almost_prime, init_fns, init_image)
11344 (flush_pending_output, init_sound):
11345 * mem-limits.h (start_of_data):

11351 Add decls with ATTRIBUTE_CONST.
11353 Minor improvements to make_formatted_string.
11354 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
11355 where int is good enough, as vsprintf returns an int.
11356 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
11358 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11360 Use make_formatted_string to avoid double length calculation.
11361 * lisp.h (make_formatted_string): New prototype.
11362 * alloc.c (make_formatted_string): New function.
11363 * buffer.c (Fgenerate_new_buffer_name): Use it.

11383 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
11385 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11387 Move marker debugging code under MARKER_DEBUG.
11388 * marker.c (MARKER_DEBUG): Move marker debugging code under
11389 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11390 for bootstrap with --enable-checking (~3x slowdown reported
11391 by Juanma Barranquero <lekktu@gmail.com>).
11392 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
11394 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
11396 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
11397 See <http://bugs.gnu.org/11825#29>.
11399 2012-07-08 Eli Zaretskii <eliz@gnu.org>
11401 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11402 has no font, use the frame's font. (Bug#11813)
11403 (display_line): Add commentary about displaying truncation glyphs
11405 (produce_special_glyphs): Move here from term.c.
11407 * term.c (produce_special_glyphs): Move to xdisp.c.
11409 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11412 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11414 * xdisp.c (display_line): Avoid warning about implicit declaration
11417 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11419 * lisp.h: Remove empty conditional.
11421 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11423 * lread.c (load_path_check): Now static.
11425 Fix some minor --with-ns problems found by static checking.
11426 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11427 (x_set_font) [!HAVE_X_WINDOWS]:
11428 * image.c (xpm_load_image) [HAVE_NS]:
11429 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11430 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11431 Remove unused local.
11432 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11433 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11434 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11435 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11436 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11437 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11438 Fix pointer signedness problem.
11439 * xfaces.c (FRAME_X_FONT_TABLE):
11440 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11442 2012-07-07 Glenn Morris <rgm@gnu.org>
11444 * lread.c (load_path_check): New function, split from init_lread.
11445 (init_lread): Reorganize. Motivation:
11446 If EMACSLOADPATH is set, check/warn about that rather than the
11447 defaults, which we are not going to use. Hence we can remove
11448 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11449 Don't warn if site-lisp directories are missing.
11450 If not installed, start from a blank load-path, since
11451 PATH_LOADSEARCH refers to the eventual installation directories.
11453 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11455 Support truncation and continuation glyphs on GUI frames, when
11456 fringes are disabled. (Bug#11832)
11457 * xdisp.c (init_iterator): Get dimensions of truncation and
11458 continuation glyphs even if on GUI frames.
11459 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11460 or both, are absent.
11461 (start_display, move_it_in_display_line_to): Handle the case of a
11462 GUI frame without a fringe to display continuation or truncation
11464 (insert_left_trunc_glyphs): Support GUI frames: make sure
11465 truncation glyphs overwrite enough glyphs from the current line to
11466 have sufficient space in pixels.
11467 (display_line): Support truncation and continuation glyphs on GUI
11468 frames. If some spare pixels are left on the line after inserting
11469 the truncation glyphs, fill that space with a stretch glyph of a
11470 suitably computed width.
11472 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11473 produce_glyphs, to support GUI sessions.
11475 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11477 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11479 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11481 Do not require float-time's arg to fit in time_t (Bug#11825).
11482 This works better on hosts where time_t is unsigned, and where
11483 float-time is applied to the (negative) difference between two times.
11484 * editfns.c (decode_time_components): Last arg is now double *,
11485 not int *, and means to store all the result as a double, without
11486 worrying about whether the seconds part fits in time_t.
11487 All callers changed.
11488 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11489 All callers changed.
11490 (Ffloat_time): Do not fail merely because the specified time falls
11491 outside of time_t range.
11493 2012-07-07 Glenn Morris <rgm@gnu.org>
11495 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11496 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11497 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11499 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11501 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11502 Update dependencies.

11510 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11511 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11512 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11513 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11515 * xfont.c (compare_font_names): Redo to omit the need for casts.
11517 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11519 * xfns.c (Fx_change_window_property): Doc fix.
11520 * w32fns.c (Fx_change_window_property): Doc fix.
11522 * w32fns.c (Fx_window_property): Accept the same arguments as the
11523 X Windows version. Doc fix.
11524 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11526 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11527 Eli Zaretskii <eliz@gnu.org>
11529 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11530 Windows-specific code from nt/config.nt moved here.
11531 Obsolete settings removed.
11533 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11535 * process.c: Avoid unnecessary calls to gettime.
11536 (wait_reading_process_output): Don't get the time of day
11537 when gobbling data immediately and not waiting, as there's no need
11538 for it in that case. This removes a FIXME.
11540 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11542 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11543 is defined (Bug#11768).
11545 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11547 Fix marker debugging code.
11548 * marker.c (byte_char_debug_check): Do not perform the check
11549 if buffer is not multibyte.
11550 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11551 Call byte_char_debug_check with correct arguments.
11553 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11555 Compile marker debugging code only if ENABLE_CHECKING is defined.
11556 * marker.c (byte_char_debug_check, count_markers):
11557 Use only if ENABLE_CHECKING is defined.
11558 (byte_debug_flag): Remove.
11559 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11560 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11562 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11564 Avoid code repetition in marker-related functions.
11565 * marker.c (attach_marker): New function.

11569 Consistently rename charno to charpos.
11570 (marker_position): Add eassert.
11571 (marker_byte_position): Convert to eassert.
11573 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11575 Simplify list operations in unchain_overlay and unchain_marker.

11587 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11588 (save_restriction_save): Use build_marker.
11589 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11590 * window.c (save_window_save): Likewise.
11592 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11594 Do not use Fdelete_overlay in delete_all_overlays

11597 (delete_all_overlays, Fdelete_overlay): Use it.
11598 * minibuf.c (get_minibuffer): Fix comment.
11600 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11602 Port to OpenBSD 5.1 amd64.
11603 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11604 This is needed for OpenBSD, and should be harmless on all BSD systems.
11605 Also, include <sys/sysctl.h>, as it should be available on all
11606 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11607 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11608 use p_pid member, not kp_proc.pid.
11610 2012-07-06 Glenn Morris <rgm@gnu.org>
11612 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

11625 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11627 Omit needless casts involving void * pointers and allocation.
11628 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11629 as the former is more robust if P's type is changed.
11630 Prefer xzalloc to xmalloc + memset 0.
11631 Simplify malloc-or-realloc to realloc.
11632 Don't worry about xmalloc returning a null pointer.
11633 Prefer xstrdup to xmalloc + strcpy.
11634 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11636 * keyboard.c (apply_modifiers_uncached): Prefer local array to

11641 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11642 hscroll is larger than the line width. Fixes long and futile
11643 looping inside extend_face_to_end_of_line (on a TTY) producing
11644 glyphs that are not needed and thrown away.
11646 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11648 * marker.c (set_marker_restricted_both): Simplify by using
11651 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

11662 followed by gtk_box_set_homogeneous (Bug#11768).
11663 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11664 (update_theme_scrollbar_width, xg_create_scroll_bar):
11665 Use gtk_scrollbar_new (Bug#11768).
11666 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11667 (is_box_type): New function (Bug#11768).
11668 (xg_tool_item_stale_p): Call is_box_type.
11669 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11670 with default display (Bug#11768).
11672 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11674 * xdisp.c (window_hscroll_limited): New function.
11675 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11676 coordinates when window's hscroll is set to insanely large
11677 values. (Bug#11857)
11679 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
11681 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

11742 * fileio.c (time_error_value): Check the right error number.
11743 Problem reported by Troels Nielsen in
11744 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11746 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11748 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11749 This should be fixed in a better way; see Eli Zaretskii in
11750 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11751 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11753 * fileio.c (time_error_value): Rename from special_mtime.
11754 The old name's problems were noted by Eli Zaretskii in
11755 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11757 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11758 This variable's comment says Emacs needs at least one GDB-visible
11759 symbol of type enum pvec_type, to work around GDB problems.
11760 The symbol's value doesn't matter.
11762 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11763 that causes compilation to fail on pre-C99 compilers.
11765 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11767 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

11770 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11772 * buffer.c (init_buffer_once): Fix initialization of
11773 headers for buffer_defaults and buffer_local_symbols.
11774 Reported by Juanma Barranquero <lekktu@gmail.com>.
11776 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11778 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11779 * lisp.h (enum pvec_type): Use fewer bits.
11780 (PSEUDOVECTOR_SIZE_BITS): New constant.
11781 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11782 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11783 change in pvec_type.
11784 (PSEUDOVECTOR_TYPEP): New macro.
11785 (TYPED_PSEUDOVECTORP): Use it.
11786 * fns.c (internal_equal): Adapt code to extract pvectype.
11787 * emacs.c (gdb_pvec_type): Update type.
11788 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11789 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11790 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11791 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11792 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11793 abusing vector->header.next.nbytes.
11794 (live_vector_p): Use PVEC_TYPE.
11795 (mark_object): Adapt code to extract pvectype. Use switch.
11797 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11799 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11800 Tighten new eassert a bit.
11802 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11804 Fix compilation with --enable-gcc-warnings and -O1
11805 optimization level.
11806 * doprnt.c (doprnt): Change type of tem to int, initialize
11807 to avoid compiler warning. Add eassert.
11808 * search.c (simple_search): Initialize match_byte to avoid
11809 compiler warning. Add eassert.
11811 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11813 Avoid weird behavior with large horizontal scrolls.
11814 Without this change, for example, large hscroll values would
11815 mess up Emacs's display on Fedora 15 x86, presumably due to
11816 overflows in int calculations in the display code.
11817 Also, if buffers had long lines, Emacs would freeze.
11818 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11819 (set_window_hscroll): New function, containing the old guts of
11820 Fset_window_hscroll. Return the clipped value.
11821 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11822 This avoids the need to check against PTRDIFF_MAX.
11824 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11826 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11828 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11830 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11832 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11833 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11834 since GCC 4.4.6 issues a bogus warning for them.
11836 Fix bugs in file timestamp newness comparisons.
11837 * fileio.c (Ffile_newer_than_file_p):
11838 * lread.c (Fload): Use full timestamp resolution of files,
11839 not just the 1-second resolution, so that files that are only
11840 slightly newer still count as newer.
11841 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11842 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11844 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11846 * fileio.c: Improve handling of file time marker. (Bug#11852)
11847 (special_mtime): New function.
11848 (Finsert_file_contents, Fverify_visited_file_modtime):
11849 Use it to set special mtime values consistently.
11851 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11853 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11854 marker for non-existing file. (Bug#11852)
11856 2012-07-03 Glenn Morris <rgm@gnu.org>
11858 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11859 and did not make it into globals.h).
11861 2012-07-03 Tom Tromey <tromey@redhat.com>
11863 * window.c (Fset_window_margins, Fset_window_fringes)
11864 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11865 * textprop.c (Fprevious_property_change): No longer static.

11894 * w32term.h: Remove EXFUNs.

11897 * xterm.h: Remove EXFUN.
11899 2012-07-03 Glenn Morris <rgm@gnu.org>
11901 * lisp.h (Frandom): Make it visible to C.
11902 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11903 buffer for invisible buffers. (Bug#1229)
11905 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11907 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11908 values which aren't power of 2.
11909 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11910 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11913 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11915 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11917 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11919 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11921 * alloc.c (allocate_vector_block): Remove redundant
11922 calls to mallopt if DOUG_LEA_MALLOC is defined.
11923 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11924 avoid calls to mallopt if zero_vector is returned.
11926 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11928 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11929 is enabled, avoid dereferencing NULL current_sblock if
11932 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11934 Cleanup basic buffer management.
11935 * buffer.h (struct buffer): Change layout to use generic vector
11936 marking code. Fix some comments. Change type of 'clip_changed'
11937 to bitfield. Remove unused #ifndef old.
11938 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11939 (GET_OVERLAYS_AT): Fix indentation.
11940 (for_each_per_buffer_object_at): New macro.
11941 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

11945 struct buffer. Fix comment.
11946 (mark_overlay): New function.
11947 (mark_buffer): Use it. Use mark_vectorlike to mark normal

11949 (mark_object): Use it. Adjust marking of misc objects
11950 and related comments.
11952 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11954 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11955 wrapper that is not needed because the wrapped code is a no-op (zero
11956 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11957 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11959 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11961 * alloc.c (mark_buffer): Simplify. Remove prototype.
11962 (mark_object): Add comment. Reorganize marking of vector-like
11963 objects. Use CHECK_LIVE for all vector-like objects except buffers
11964 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11965 Avoid redundant calls to mark_vectorlike for bool vectors.
11967 2012-06-30 Glenn Morris <rgm@gnu.org>
11969 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11971 * epaths.in (PATH_SITELOADSEARCH): New.
11972 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11973 This is rather than relying on --enable-locallisppath elements
11974 having "site-lisp" in their names. (Bug#10208#25, 11658)
11976 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11978 * w32proc.c (sys_select): Accept and ignore one more argument.
11980 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11982 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11983 (pselect) [!MS_DOS]: Redirect to sys_select.
11985 * sysdep.c: Don't include dos.h and dosfns.h.
11987 * process.c (sys_select):
11988 * msdos.c (sys_select): Accept one more argument and ignore it.
11990 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11991 adapt data types and code to that.
11994 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11995 which clashes with the gnulib function of the same name.
11997 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11999 * font.c (font_style_to_value, font_style_symbolic)
12000 (font_prop_validate_style): Add type checks for values in
12003 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
12005 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
12008 2012-06-29 Eli Zaretskii <eliz@gnu.org>
12010 * xdisp.c (try_window_id): Undo last change.
12012 * w32.c (getwd): Adjust commentary about startup_dir.
12013 (init_environment): Always call sys_access, even in non-MSVC
12014 builds. Don't chdir to the directory of the Emacs executable.
12015 This undoes code from 1997 which was justified by the need to
12016 "avoid conflicts when removing and renaming directories". But its
12017 downside was that every relative file name was being interpreted
12018 relative to the directory of the Emacs executable, which can never
12019 be TRT. In particular, it broke sys_access when called with
12020 relative file names.
12021 (sys_access): Map GetLastError to errno.
12023 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

12029 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
12032 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
12034 * gnutls.c (emacs_gnutls_handshake):
12035 Add QUIT to make the loop interruptible.
12037 2012-06-29 Glenn Morris <rgm@gnu.org>
12039 * charset.c (init_charset): Make lack of etc/charsets fatal.
12041 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
12043 * editfns.c (region_limit): Fix type mismatch.
12045 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
12047 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
12048 undefined. Convert from xassert to eassert.
12049 * nsmenu.m: Convert from xassert to eassert.
12050 * nsterm.m: Likewise.
12052 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
12054 * editfns.c (region_limit): Clip to narrowing (bug#11770).
12056 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
12058 Avoid integer overflow on scroll-left and scroll-right.
12059 * window.c (HSCROLL_MAX): New macro.
12060 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
12061 overflow when requested scroll falls outside ptrdiff_t range.
12063 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
12065 * window.h (struct window): Change type of 'hscroll',
12066 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
12067 'last_modified' and 'last_overlay_modified' to EMACS_INT.
12068 Adjust users accordingly.
12069 * xdisp.c (try_cursor_movement): Replace type check with eassert.
12070 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
12071 from EMACS_INT to ptrdiff_t.
12072 (make_window): Omit redundant initialization.
12074 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

12091 Fix GLYPH_DEBUG usage assuming that it may be undefined,
12092 adjust comments accordingly.

12171 on Mac OS X Lion: __mod_init_func and __mod_term_func.
12173 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
12174 when building with Clang.
12176 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

12205 * alloc.c: Remove build_string.
12206 * lisp.h: Define build_string as static inline. This provides
12207 a better opportunity to optimize away calls to strlen when the
12208 function is called with compile-time constant argument.
12209 * image.c (imagemagick_error): Convert to build_string.
12210 * w32proc.c (sys_spawnve): Likewise.
12211 * xterm.c (x_term_init): Likewise.
12213 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12215 Use sprintf return value instead of invoking strlen on result.
12216 In the old days this wasn't portable, since some sprintf
12217 implementations returned char *. But they died out years ago and
12218 Emacs already assumes sprintf returns int.
12219 Similarly for float_to_string.
12220 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
12221 * ccl.c (ccl_driver):

12225 * print.c (print_object):
12226 * xdisp.c (message_dolog):
12227 * xfns.c (syms_of_xfns):
12228 Use sprintf or float_to_string result to avoid need to call strlen.
12229 * data.c (Fnumber_to_string):
12230 Use make_unibyte_string, since the string must be ASCII.
12231 * lisp.h, print.c (float_to_string): Now returns int length.
12232 * term.c (produce_glyphless_glyph):
12233 Use sprintf result rather than recomputing it.
12235 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
12236 * Makefile.in (ALL_CFLAGS):
12237 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
12238 * gmalloc.c, regex.c: Include <config.h> unconditionally.
12240 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12242 * dispextern.h (xstrcasecmp): Define to library function
12243 strcasecmp if available.

12259 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
12261 * gtkutil.c (get_utf8_string): Remove redundant assignment.
12262 sprintf already null-terminates its output.
12264 * xfns.c (x_window): Remove redundant cast.
12266 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12268 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
12269 `const char *' to `char *' to avoid compiler warning.
12271 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12273 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12274 instead of truncating it to 63 (admittedly a generous limit).
12276 * process.c: Fix spelling and caps in comments.
12278 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
12280 * emacs.c (setpgrp): Remove definition, unused.

12294 * s/ms-w32.h (struct timespec): Definition moved from
12295 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
12297 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

12327 Remove unnecessary forward decls.
12329 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12331 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
12332 * lisp.h (WAIT_READING_MAX): New macro.
12333 * dispnew.c (Fsleep_for, sit_for):
12334 * keyboard.c (kbd_buffer_get_event):
12335 * process.c (Faccept_process_output):
12336 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
12337 This improves on the previous patch, which introduced a bug
12338 when time_t is unsigned and as wide as intmax_t.
12339 See <http://bugs.gnu.org/9000#51>.
12341 2012-06-23 Eli Zaretskii <eliz@gnu.org>
12343 * dispnew.c (sit_for, Fsleep_for):
12344 * keyboard.c (kbd_buffer_get_event):
12345 * process.c (Faccept_process_output): Avoid compiler warnings when

12348 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
12350 * makefile.w32-in: Update dependencies.

12357 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
12358 Privately reported by Herbert J. Skuhra.
12359 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
12361 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
12362 not make_lisp_timeval, when the argument is of type EMACS_TIME.
12364 2012-06-23 Eli Zaretskii <eliz@gnu.org>
12366 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
12367 last argument of make_unibyte_string.
12369 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
12370 language ID in the event parameters.
12372 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12373 event.code, not the obscure "character set ID".
12375 2012-06-23 Chong Yidong <cyd@gnu.org>
12377 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

12400 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
12401 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
12402 Don't assume EMACS_TIME and struct timeval are the same type.
12404 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12406 Support higher-resolution time stamps (Bug#9000).
12407 The time stamps are only nanosecond-resolution at the C level,
12408 since that's the best that any real-world system supports now.
12409 But they are picosecond-resolution at the Lisp level, as that's
12410 easy, and leaves room for future OS improvements.
12412 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12415 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12416 Don't get current time unless it's needed.
12418 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12419 now provides it if it's absent.
12420 (start_atimer): Port to higher-res time stamps.
12421 Check for time stamp overflow. Don't get current time more
12422 often than is needed.
12424 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12425 Include systime.h, not time.h.
12426 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12428 * dired.c: Include stat-time.h.
12429 (Ffile-attributes): File times now have higher resolution.
12431 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12432 (struct image): Timestamp now has higher resolution.
12434 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12435 has at least microseconds now. All uses removed.
12436 (update_frame, update_single_window, update_window, update_frame_1)
12437 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12438 (duration_to_sec_usec): Remove; no longer needed.
12440 * editfns.c (time_overflow): Now extern.
12441 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12442 (float-time, Fformat_time_string, Fcurrent_time_string)

12445 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
12446 (decode_time_components, lisp_seconds_argument): New functions.
12447 (make_time): Now static.
12448 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12449 Report an error if the time is invalid, rather than having the caller
12452 * fileio.c: Include <stat-time.h>
12453 (Fcopy_file): Copy higher-resolution time stamps.
12454 Prefer to set the time stamp via a file descriptor if that works.
12455 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12456 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12457 (Fvisited_file_modtime, Fset_visited_file_modtime):
12458 Support higher-resolution time stamps.
12460 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12462 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12464 * image.c (prepare_image_for_display, clear_image_cache)
12465 (lookup_image): Port to higer-resolution time stamps.
12467 * keyboard.c (start_polling, bind_polling_period):
12468 Check for time stamp overflow.
12469 (read_char, kbd_buffer_get_event, timer_start_idle)
12470 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12471 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12472 Port to higher-resolution time stamps. Do not assume time_t is signed.
12473 (decode_timer): New function. Timers are now vectors of length 9,
12474 not 8, to accommodate the picosecond component.
12475 (timer_check_2): Use it.
12477 * nsterm.m (select_timeout, timeval_subtract): Remove.
12478 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12479 as they're a bit more accurate and handle overflow better.
12480 (ns_select): Change prototype to be compatible with pselect.
12481 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12482 * nsterm.h (ns_select): Adjust prototype.
12484 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12485 us-resolution time stamps.
12486 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12488 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12490 * lisp.h (time_overflow): New decl.
12491 (wait_reading_process_output): First arg is now intmax_t, not int,
12492 to accommodate larger waits.
12494 * process.h (struct Lisp_Process.read_output_delay):
12495 Now counts nanoseconds, not microseconds.
12496 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12498 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12499 (wait_reading_process_output):
12500 Port to ns-resolution time stamps.
12501 (Faccept_process_output, wait_reading_process_output):
12502 Check for time stamp overflow. Do not assume time_t is signed.
12503 (select_wrapper): Remove; we now use pselect.
12504 (Fprocess_attributes): Now generates ns-resolution time stamps.
12506 * sysdep.c: Include utimens.h. Don't include utime.h
12507 or worry about struct utimbuf; gnulib does that for us now.
12508 (gettimeofday): Remove; gnulib provides a substitute.
12509 (make_timeval): New function.
12510 (set_file_times): Now sets ns-resolution time stamps.
12511 New arg FD; all uses changed.
12512 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12513 (system_process_attributes):
12514 Now returns ns-resolution time stamp. All uses changed.
12515 Check for time stamp overflow.
12517 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12518 provides a substitute now.
12520 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12521 since it guarantees struct timespec.
12522 (EMACS_TIME): Now struct timespec, so that we can support
12523 ns-resolution time stamps.
12524 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12525 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12526 (EMACS_USECS): Remove.
12527 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12528 so multiply the arg by 1000 before storing it.
12529 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12531 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12532 Port to ns-resolution time stamps.
12533 (EMACS_TIME_NEG_P): Remove; replaced by....
12534 (EMACS_TIME_SIGN): New macro.
12535 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
12536 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12537 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12538 (make_timeval, make_lisp_time, decode_time_components): New decls.
12539 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12540 that it mishandled time_t overflow. You can't compare by subtracting!
12541 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12542 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12544 * term.c: Include <sys/time.h>.
12545 (timeval_to_Time): New function, for proper overflow wraparound.
12546 (term_mouse_position, term_mouse_click): Use it.
12548 * undo.c (record_first_change): Support higher-resolution time stamps
12549 in the undo buffer.
12550 (Fprimitive_undo): Use them when restoring time stamps.
12552 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12553 (w32_get_internal_run_time):
12554 Port to higher-resolution Emacs time stamps.
12555 (ltime): Now accepts single 64-bit integer, as that's more convenient
12558 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12560 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12561 for compatibility with pselect. Support ns-resolution time stamps.
12563 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12565 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12566 Check for time stamp overflow, and support ns-resolution time stamps.
12568 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12569 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12570 (timeval_subtract): Remove; no longer needed.
12571 (XTflash, XTring_bell, x_wait_for_event):
12572 Port to ns-resolution time stamps. Don't assume time_t is signed.
12574 2012-06-22 Chong Yidong <cyd@gnu.org>
12576 * xdisp.c (x_consider_frame_title): Revert last change.
12578 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12580 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12581 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12582 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12583 staticidx goes up to 1597 out of 1600 = 0x640.)
12585 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12587 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12588 Otherwise, the umask might be mistakenly 0 while handling input signals.
12590 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
12592 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

12598 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
12599 access to `contents' member of Lisp_Vector objects with AREF and ASET
12602 2012-06-19 Chong Yidong <cyd@gnu.org>
12604 * frame.c (delete_frame): When selecting a frame on a different
12605 text terminal, do not alter the terminal's top-frame.
12607 * xdisp.c (format_mode_line_unwind_data): Record the target

12858 Use an inline function on all platforms when using the union type,

13004 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
13005 would mishandle a string argument "Xc" if X was a multibyte

13060 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
13061 Convert pctcpu and pctmem to Lisp float properly.
13062 Let the compiler fold better, as 100.0/0x8000 is exact.
13064 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
13066 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
13069 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
13071 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
13073 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
13075 For a 'struct window', replace some Lisp_Object fields to
13076 bitfields where appropriate, remove unused fields.
13077 * window.h (struct window): Remove unused 'last_mark_x' and
13078 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
13079 change its type from Lisp_Object to bitfield.
13080 Change type of 'force_start', 'optional_new_start',
13081 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
13082 fields from Lisp_Object to bitfield. Adjust users accordingly.
13084 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13086 Pacify gcc -Wdouble-precision when using Xaw.
13087 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
13088 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
13089 Use 'float' consistently, rather than 'float' in most places
13090 and 'double' in a couple of places.
13092 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13094 * xdisp.c (handle_stop): Detect whether we have overlay strings
13095 loaded by testing it->current.overlay_string_index to be
13096 non-negative, instead of checking whether n_overlay_strings is
13097 positive. (Bug#11587)
13099 2012-05-31 Chong Yidong <cyd@gnu.org>
13101 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
13103 * doc.c (Fsubstitute_command_keys): Doc fix.
13105 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13107 * search.c (search_buffer): Remove calls to
13108 r_alloc_inhibit_buffer_relocation, as it is now called by
13109 maybe_unify_char, which was the cause of relocation of buffer text
13112 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13114 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
13115 for the duration of call to load_charset, to avoid problems with
13116 callers of maybe_unify_char that access buffer text through C
13119 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
13120 decrement the inhibition flag, instead of just setting or
13123 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13125 Remove obsolete '#define static' cruft.
13126 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
13127 This #undef was "temporary" in 2000; it is no longer needed
13128 now that '#define static' has gone away.
13129 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
13130 (gray_bitmap_bits): Remove; no longer needed.
13131 All uses replaced with definiens.
13132 * xterm.c: Include "bitmaps/gray.xbm".
13134 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13136 Clean up __executable_start, monstartup when --enable-profiling.
13137 The following changes affect the code only when profiling.
13138 * dispnew.c (__executable_start): Rename from safe_bcopy.
13139 Define only on platforms that need it.
13140 * emacs.c: Include <sys/gmon.h> when profiling.
13141 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
13142 (__executable_start): Remove decl, since lisp.h does it now.
13143 (safe_bcopy): Remove decl; no longer has that name.
13144 (main): Coalesce #if into single bit of code, for simplicity.
13145 Cast pointers to uintptr_t, since standard libraries want integers
13147 * lisp.h (__executable_start): New decl.
13149 2012-05-31 Glenn Morris <rgm@gnu.org>
13151 * image.c (Fimagemagick_types): Doc fix.
13153 2012-05-30 Jim Meyering <meyering@redhat.com>
13155 * callproc.c (Fcall_process_region): Include directory component
13156 in mkstemp error message (Bug#11586).
13158 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13160 * alloc.c, lisp.h (make_pure_vector): Now static.
13162 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
13164 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
13165 Move to byte-run.el.
13166 (Fautoload): Do the hash-doc more carefully.
13167 * data.c (Fdefalias): Purify definition, except for keymaps.
13168 (Qdefun): Move from eval.c.
13169 * lisp.h (Qdefun): Remove.
13170 * lread.c (read1): Tiny simplification.
13172 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
13174 Do not create empty overlays with the evaporate property (Bug#9642).
13175 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13176 Bug#9642, but explicitly check that the buffer the overlay would
13177 be moved to is live and rearrange lines to make sure that errors
13178 will not put the overlay in an inconsistent state.
13179 (Fdelete_overlay): Cosmetics.
13181 2012-05-28 Eli Zaretskii <eliz@gnu.org>
13183 * w32term.c (my_bring_window_to_top): New function.
13184 (x_raise_frame): Use handle returned by DeferWindowPos, which
13185 could be different from the original one.
13186 Call my_bring_window_to_top instead of my_set_foreground_window.
13189 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
13190 by calling BringWindowToTop.
13192 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

13195 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
13197 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13198 This avoids undefined behavior that might cause the eassert
13199 to not catch an out-of-range value.
13201 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13203 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
13204 Update dependencies.
13206 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13208 * bidi.c (bidi_mirror_char): Fix last change.
13210 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
13212 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
13213 when referring to sectname field in printf format.
13215 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
13217 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
13218 Only r_alloc_inhibit_buffer_relocation needed to be added;
13219 the others were already declared.
13221 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13222 before checking whether it's out of range. Put the check inside
13224 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
13226 2012-05-27 Ken Brown <kbrown@cornell.edu>
13228 * callproc.c (Fcall_process): Restore a line that was accidentally
13229 commented out in the 2011-02-13 change (bug#11547).
13231 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13233 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13234 defined on ralloc.c.
13236 * buffer.c [REL_ALLOC]: Remove prototypes of
13237 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
13238 they are now on lisp.h.
13240 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13242 * search.c (search_buffer): Use it to inhibit relocation of buffer
13243 text while re_search_2 is doing its job, because re_search_2 is
13244 passed C pointers to buffer text. (Bug#11519)
13246 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13247 Update value to 24.
13249 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13250 state after an additional call to move_it_in_display_line_to, keep
13251 the values of it->max_ascent and it->max_descent found for the
13253 (pos_visible_p): Revert the comparison against bottom_y to what it
13254 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13257 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13259 Fix coding-related core dumps with gcc -ftrapv.
13260 The code was computing A - B, where A and B are pointers, and B is
13261 random garbage. This can lead to core dumps on platforms that
13262 have special pointer registers, and it also leads to core dumps on
13263 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13264 A - B only when B is initialized properly.
13265 * coding.c (coding_set_source, coding_set_destination): Return void.
13266 (coding_change_source, coding_change_destinations): New functions,
13267 with the old behaviors of coding_set_source and coding_set_destination.
13268 All callers that need an offset changed to use these new functions.
13270 2012-05-26 Glenn Morris <rgm@gnu.org>
13272 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
13274 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13276 Extend mouse support on W32 text-mode console.
13277 * xdisp.c (draw_row_with_mouse_face):
13278 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13280 * w32console.c: Include window.h.
13281 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13283 (initialize_w32_display): Initialize mouse-highlight data.
13285 * w32inevt.c: Include termchar.h and window.h.
13286 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13287 moves, call note_mouse_highlight. If help_echo changed, call
13288 gen_help_event to produce help-echo message in the echo area.
13289 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13292 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13294 * lread.c (read1): Simplify slightly to avoid an overflow warning
13295 with GCC 4.7.0 on x86-64.
13297 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13299 * bidi.c (bidi_mirror_char): Revert last change: an int is
13300 definitely wide enough here.
13302 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13304 Fix integer width and related bugs (Bug#9874).
13305 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
13306 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
13307 (string_bytes, check_sblock, allocate_string_data):
13308 (compact_small_strings, Fmake_bool_vector, make_string)
13309 (make_unibyte_string, make_multibyte_string)
13310 (make_string_from_bytes, make_specified_string)
13311 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
13312 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
13314 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13315 (allocate_pseudovector):
13316 Use int, not EMACS_INT, where int is wide enough.
13317 (inhibit_garbage_collection, Fgarbage_collect):
13318 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13319 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13320 int might not be wide enough.
13321 (bidi_cache_search, bidi_cache_find, bidi_init_it)
13322 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
13323 (bidi_at_paragraph_end, bidi_find_paragraph_start)
13324 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
13325 (bidi_level_of_next_char, bidi_move_to_visually_next):
13326 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13327 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
13328 (Fkill_buffer, Fset_buffer_major_mode)
13329 (advance_to_char_boundary, Fbuffer_swap_text)
13330 (Fset_buffer_multibyte, overlays_at, overlays_in)
13331 (overlay_touches_p, struct sortvec, record_overlay_string)
13332 (overlay_strings, recenter_overlay_lists)
13333 (adjust_overlays_for_insert, adjust_overlays_for_delete)
13334 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
13335 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
13336 (Foverlay_recenter, last_overlay_modification_hooks_used)
13337 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13338 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13339 (validate_region): Omit unnecessary test for b <= e,
13340 since that's guaranteed by the previous test.
13341 (adjust_overlays_for_delete): Avoid pos + length overflow.
13342 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13343 (report_overlay_modification):
13344 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13345 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13346 Omit pointer cast, which isn't needed anyway, and doesn't work
13347 after the EMACS_INT -> ptrdiff_t change.
13348 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13349 * buffer.h: Adjust decls to match defn changes elsewhere.
13350 (struct buffer_text, struct buffer):
13351 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13352 Use EMACS_INT, not int, where int might not be wide enough.
13353 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13354 not int, to avoid needless 32-bit limit on 64-bit hosts.
13355 (exec_byte_code): Use tighter memory-full test, one that checks
13356 for alloca overflow. Don't compute the address of the object just
13357 before an array, as that's not portable. Use EMACS_INT, not
13358 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13359 * callint.c (Fcall_interactively):
13360 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13361 * callproc.c (call_process_kill, Fcall_process):
13362 Don't assume pid_t fits into an Emacs fixnum.
13363 (call_process_cleanup, Fcall_process, child_setup):
13364 Don't assume pid_t fits into int.
13365 (call_process_cleanup, Fcall_process, delete_temp_file)
13366 (Fcall_process_region):
13367 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13368 (Fcall_process): Simplify handling of volatile integers.
13369 Use int, not EMACS_INT, where int will do.
13370 * casefiddle.c (casify_object, casify_region, operate_on_word)
13371 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13372 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13373 (casify_object): Avoid integer overflow when overallocating buffer.
13374 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13375 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13376 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13377 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13378 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13379 integers are now checked earlier. All uses replaced with XINT.
13381 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13382 For CCL_MapSingle, check that content and value are in int range.
13383 (ccl_driver, Fregister_code_conversion_map):
13384 Check that Vcode_version_map_vector is a vector.
13385 (resolve_symbol_ccl_program): Check that vector header is in range.
13386 Always copy the vector, so that we can check its contents reliably
13387 now rather than having to recheck each instruction as it's being
13388 executed. Check that vector words fit in 'int'.
13389 (ccl_get_compiled_code, Fregister_ccl_program)
13390 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13391 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13392 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13393 contents are in range.
13394 (Fccl_execute_on_string): Check that status is in range.
13395 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13396 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13397 Accept and return EMACS_INT, not int, because callers can pass values
13398 out of 'int' range.
13399 (c_string_width, strwidth, lisp_string_width, chars_in_text)
13400 (multibyte_chars_in_text, parse_str_as_multibyte)
13401 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
13402 (str_as_unibyte, str_to_unibyte, string_count_byte8)
13403 (string_escape_byte8, Fget_byte):
13404 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13405 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13406 avoid mishandling large integers.
13407 * character.h: Adjust decls to match defn changes elsewhere.
13408 * charset.c (load_charset_map_from_file, find_charsets_in_text)
13409 (Ffind_charset_region):
13410 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13411 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
13412 (load_charset_map_from_vector, Fdefine_charset_internal):
13413 Don't assume fixnum fits in int.
13414 (load_charset_map_from_vector, Fmap_charset_chars):
13415 Remove now-unnecessary CHECK_NATNUMs.
13416 (Fdefine_charset_internal): Check ranges here, more carefully.
13417 Don't rely on undefined behavior with signed left shift overflow.
13418 Don't assume unsigned int fits into fixnum, or that fixnum fits
13419 into unsigned int. Don't require max_code to be a valid fixnum;
13420 that's not true for gb10830 4-byte on a 32-bit host. Allow
13421 invalid_code to be a cons, for the same reason. Require code_offset
13422 to be a character. Avoid int overflow if max_char is close
13424 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13425 this is intended anyway and avoids some undefined behavior.
13426 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13427 INDEX_TO_CODE_POINT, as that's what it expects.
13428 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13429 * charset.h (DECODE_CHAR): Return int, not unsigned;
13430 this is what was intended anyway, and it avoids undefined behavior.
13431 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13432 integer-overflow issues.
13433 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13434 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13435 where the argument is EMACS_INT, and this behavior is not intended.
13436 * chartab.c (Fmake_char_table, Fset_char_table_range)
13437 (uniprop_get_decoder, uniprop_get_encoder):
13438 Don't assume fixnum fits in int.
13439 * cmds.c (move_point): New function, that does the gist of
13440 Fforward_char and Fbackward_char, but does so while checking
13441 for integer overflow more accurately.
13442 (Fforward_char, Fbackward_char): Use it.
13443 (Fforward_line, Fend_of_line, internal_self_insert)
13444 (internal_self_insert):
13445 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13446 Fix a FIXME, by checking for integer overflow when calculating
13447 target_clm and actual_clm.
13448 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
13449 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

14140 Use VAL_MAX, not VALBITS, in #if.
14141 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
14142 (EMACS_UINT): Define unconditionally now.
14143 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
14144 (BITS_PER_EMACS_INT): New constants, replacing
14145 what used to be in config.h, but not useful in #if.
14146 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
14147 define them any more.
14148 (VAL_MAX): New macro.
14150 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
14151 BITS_PER_EMACS_INT, in #if.
14152 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
14153 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
14154 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
14155 * s/ms-w32.h (DATA_START):
14156 Move here from removed file m/intel386.h.
14157 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
14158 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
14160 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
14162 Assume C89 or later.
14163 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
14164 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
14166 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
14167 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
14168 * textprop.c, tparam.c (NULL): Remove.
14169 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
14170 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
14171 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
14172 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
14173 * xterm.c (input_signal_count): Assume volatile works.
14175 2012-05-21 Ken Brown <kbrown@cornell.edu>
14177 * xgselect.c (xg_select): Fix first argument in call to 'select'
14180 2012-05-20 Ken Brown <kbrown@cornell.edu>
14182 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
14183 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
14185 2012-05-19 Ken Brown <kbrown@cornell.edu>
14187 * xfns.c (x_in_use): Remove `static' qualifier.
14188 * xterm.h (x_in_use): Declare.
14189 * xgselect.c: Include xterm.h.
14190 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
14191 and `display_arg' (bug#9754).
14193 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
14195 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
14197 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
14198 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
14200 2012-05-18 Eli Zaretskii <eliz@gnu.org>
14202 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
14204 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
14205 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
14207 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
14208 reference to image_cache->refcount.
14209 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
14211 2012-05-17 Juri Linkov <juri@jurta.org>
14213 * search.c (Fword_search_regexp, Fword_search_backward)
14214 (Fword_search_forward, Fword_search_backward_lax)
14215 (Fword_search_forward_lax): Move functions to isearch.el
14216 (bug#10145, bug#11381).
14218 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
14220 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
14222 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
14224 * lread.c (init_obarray): Declare Qt and Qnil as special.
14226 2012-05-14 Glenn Morris <rgm@gnu.org>
14228 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
14229 Put "libexec" before "bin", for the sake of init_callproc_1.
14231 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14233 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
14235 * unexaix.c: Port to more-recent AIX compilers.
14236 (report_error, report_error_1, make_hdr, copy_sym)
14237 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
14238 Make arguments const char *, not char *, to avoid violations of C
14239 standard and to fix some AIX warnings reported by Gilles Pion.
14241 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14243 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
14244 already have overlays loaded.
14245 (handle_single_display_spec): Before returning without displaying
14246 fringe bitmap, synchronize the bidi iterator with the main display
14247 iterator, by calling iterate_out_of_display_property.
14248 (iterate_out_of_display_property): Detect buffer iteration by
14249 testing that it->string is a Lisp string.
14250 (get_next_display_element): When the current object is exhausted,
14251 and there's something on it->stack, call set_iterator_to_next to
14252 proceed with what's on the stack, instead of returning zero.
14253 (set_iterator_to_next): If called at the end of a Lisp string,
14254 proceed to consider_string_end without incrementing string
14255 position. Don't increment display vector index past the end of
14256 the display vector. (Bug#11417)
14257 (pos_visible_p): Don't report a position visible when move_it_to
14258 stopped at the last line of window, which happens to be scanned
14259 backwards by the bidi iteration. (Bug#11464)
14261 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14263 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14264 and right-margin display specs even if the spec is invalid or we
14265 are on a TTY, and thus unable to display on the fringes.
14266 That's because the text with the property will not be displayed anyway,
14267 so we need to signal to the caller that this is a "replacing"
14268 display spec. This fixes display when the spec is invalid or we
14271 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14273 * unexaix.c (make_hdr): Fix typo in prototype.
14274 This bug broke the build on AIX. Problem reported by Gilles Pion.
14276 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
14278 * keyboard.c (kbd_buffer_get_event): Read special events also in
14279 batch mode. (Bug#11415)
14281 2012-05-12 Glenn Morris <rgm@gnu.org>
14283 * ns.mk: Update for ns_appbindir no longer having trailing "/".
14285 2012-05-12 Eli Zaretskii <eliz@gnu.org>
14287 * lisp.mk (lisp): Add newcomment.elc.
14289 2012-05-12 Glenn Morris <rgm@gnu.org>
14291 * Makefile.in (MKDIR_P): New, set by configure.
14292 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
14294 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
14296 Remove unused function hourglass_started.
14297 * dispextern.h (hourglass_started):
14298 * w32fns.c (hourglass_started):
14299 * xdisp.c (hourglass_started): Remove.
14301 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
14303 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
14304 Update dependencies.
14306 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14308 * xgselect.c (xg_select): Put maxfds+1 into a var.
14309 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14311 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14313 2012-05-10 Dave Abrahams <dave@boostpro.com>
14315 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14316 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14318 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14320 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14321 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14322 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14323 Initialize xd_registered_buses.
14325 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14327 Untag more efficiently if USE_LSB_TAG.
14328 This is based on a proposal by YAMAMOTO Mitsuharu in
14329 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14330 For an admittedly artificial (nth 8000 longlist) benchmark on
14331 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14332 Emacs's overall text size by 1%.
14333 * lisp.h (XUNTAG): New macro.
14334 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14335 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14336 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14337 * eval.c (Fautoload):
14338 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14339 * frame.h (XFRAME): Use XUNTAG.
14341 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14342 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14343 Remove unportable assumptions about print widths of types like
14345 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14346 intptr_t when converting between pointer and integer, to avoid GCC
14347 warnings about wrong width.
14349 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14351 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14352 stack for each reader_thread, instead of defaulting to 8MB
14353 determined by the linker. This avoids failures in creating
14354 subprocesses on Windows 7, see the discussion in this thread:
14355 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14357 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14359 Fix up display of the *Minibuf-0* buffer in the mini window.
14360 * keyboard.c (read_char): Don't clear the echo area if there's no
14362 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14363 contents of *Minibuf-0*) if there's no message displayed in its stead.
14365 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14367 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14370 2012-05-06 Chong Yidong <cyd@gnu.org>
14372 * lisp.mk (lisp): Update.
14374 2012-05-05 Jim Meyering <meyering@redhat.com>
14376 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14378 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14380 * data.c (PUT_ERROR): New macro.
14381 (syms_of_data): Use it. Add new error type `user-error'.
14382 * undo.c (user_error): New function.
14383 (Fprimitive_undo): Use it.
14384 * print.c (print_error_message): Adjust print style for `user-error'.
14385 * keyboard.c (user_error): New function.
14386 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14388 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14390 Do not limit current-time-string to years 1000..9999.
14391 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14392 (Fcurrent_time_string): Support any year that is supported by the
14393 underlying localtime representation. Don't use asctime, as it
14394 has undefined behavior for years outside the range -999..9999.
14396 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14398 Fix race conditions involving setenv, gmtime, localtime, asctime.
14399 Without this fix, interrupts could mess up code that uses these
14400 nonreentrant functions, since setting TZ invalidates existing
14401 tm_zone or tzname values, and since most of these functions return
14402 pointers to static storage.
14403 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14404 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14405 Grow the critical sections to include not just invoking
14406 localtime/gmtime, but also accessing these functions' results
14407 including their tm_zone values if any, and any related TZ setting.
14408 (format_time_string): Last arg is now struct tm *, not struct tm **,
14409 so that the struct tm is saved in the critical section.
14410 All callers changed. Simplify allocation of initial buffer, partly
14411 motivated by the fact that memory allocation needs to be outside
14412 the critical section.
14414 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14416 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14417 with RESET_INTERVAL.
14419 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14420 Remove duplicated buffer name initialization.
14422 2012-05-02 Jim Meyering <jim@meyering.net>
14424 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14426 * xfns.c (x_window): Use xstrdup (Bug#11375).
14428 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14430 * xdisp.c (pos_visible_p): If already at a newline from the
14431 display string before the 'while' loop, don't walk back the glyphs
14432 from it3.glyph_row. Solves assertion violation when the display
14433 string begins with a newline (egg.el). (Bug#11367)
14435 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14437 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14440 2012-05-01 Glenn Morris <rgm@gnu.org>
14442 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14443 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14444 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14445 All were removed before 23.1.
14447 * dispnew.c: Remove HAVE_LIBNCURSES test;
14448 it is always true on relevant platforms.
14450 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14451 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14453 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14455 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14457 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14458 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14461 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14463 Do not avoid creating empty evaporating overlays (Bug#9642).
14464 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14465 That is, do not delete an evaporating overlay if it becomes
14466 empty after its bounds are adjusted to fit within its buffer.
14467 This fix caused other problems, and I'm reverting it until we get
14468 to the bottom of them.
14470 2012-04-27 Chong Yidong <cyd@gnu.org>
14472 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14474 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14476 * xdisp.c (pos_visible_p): If the window start position is beyond
14477 ZV, start the display from buffer beginning. Prevents assertion
14478 violation in init_iterator when the minibuffer window is scrolled
14479 via the scroll bar.
14481 * window.c (window_scroll_pixel_based): Likewise.
14483 2012-04-27 Chong Yidong <cyd@gnu.org>
14485 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14487 2012-04-27 Glenn Morris <rgm@gnu.org>
14489 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14490 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14492 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14494 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14495 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14497 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14499 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14500 display element, check also the underlying string or buffer
14501 character. (Bug#11341)
14503 * w32menu.c: Include w32heap.h.
14504 (add_menu_item): If the call to AppendMenuW (via
14505 unicode_append_menu) fails, disable Unicode menus only if we are
14506 running on Windows 9X/Me.
14508 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14510 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14511 (xgetint): Add missing shift for LSB tags.
14513 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14515 * keyboard.c (read_char): Don't wipe echo area for select window
14516 events: These might get delayed via `mouse-autoselect-window'
14519 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14521 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14522 manipulation of :loaded-from data.
14524 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14526 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14527 now a cons (bug#11311).
14529 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14531 Do not create empty overlays with the evaporate property (Bug#9642).
14532 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14533 if it becomes empty after its bounds are adjusted to fit within
14534 its buffer. Without this fix, in a nonempty buffer (let ((o
14535 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14536 yields an empty overlay that has the evaporate property, which is
14537 not supposed to happen.
14539 Fix minor GTK3 problems found by static checking.
14540 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14541 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14542 (struct _EmacsFixedClass, emacs_fixed_get_type):
14543 Move decls here from emacsgtkfixed.h, since they needn't be public.
14544 (emacs_fixed_get_type): Now static.
14545 (emacs_fixed_class_init): Omit unused local.
14546 (emacs_fixed_child_type): Remove; unused.
14547 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14548 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14549 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14550 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14551 (EMACS_FIXED_GET_CLASS): Remove; unused.
14552 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14554 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14555 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14557 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14559 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14560 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14561 (__malloc_size_t, __malloc_ptrdiff_t):
14562 Remove. All uses removed, replaced by the definiens if needed,
14563 since we can assume C89 or better now.
14564 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
14565 (protect_malloc_state, align, get_contiguous_space)
14566 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
14567 (malloc_atfork_handler_child, malloc_enable_thread)
14568 (malloc_initialize_1, __malloc_initialize, morecore_nolock)
14569 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
14570 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
14571 (special_realloc, _realloc_internal_nolock, _realloc_internal)
14572 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14573 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14574 Define using prototypes, not old style.

14652 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14654 * sysdep.c [__FreeBSD__]: Minor cleanups.
14655 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14656 Use Emacs indenting style more consistently. Avoid some casts.

14740 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14741 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14742 (NEED_MEM_INSERT): New macro.
14743 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14744 Remove one incorrect comment and fix another.

14780 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14781 * s/netbsd.h, s/sol2-6.h:
14782 Remove definition of GC_MARK_STACK, since the default now works.
14783 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

14811 2012-04-11 Daniel Colascione <dancol@dancol.org>
14813 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14814 against is gone. It's better to use vfork now so that when Cygwin
14815 gains a new, working vfork, we use it automatically (bug#10398).
14817 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14838 being loaded (bug#10424).
14840 2012-04-09 Glenn Morris <rgm@gnu.org>
14842 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

14870 * minibuf.c (Fread_variable): Callers changed.
14872 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14874 * xdisp.c (set_cursor_from_row): If the display string appears in
14875 the buffer at position that is closer to point than the position
14876 after the display string, display the cursor on the first glyph of
14877 the display string. Fixes cursor display when a 'display' text
14878 property immediately follows invisible text. (Bug#11094)
14880 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14882 composite.c: use 'double' consistently
14883 * composite.c (get_composition_id): Use 'double' consistently
14884 instead of converting 'float' to 'double' and vice versa; this is
14885 easier to understand and avoids a GCC warning.
14887 2012-04-09 Glenn Morris <rgm@gnu.org>
14889 * Makefile.in: Generate leim-list with bootstrap-emacs, in

14934 [!WINDOWSNT]: New macros.
14935 (init_libxml2_functions, libxml2_loaded_p): New functions.

14939 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14941 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14942 Call init_libxml2_functions before calling libxml2 functions.

14951 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14953 * indent.c (Fvertical_motion): If there is a display string at
14954 point, use it.vpos to compute how many lines to backtrack after
14955 move_it_to point. (Bug#11133)
14957 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14959 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14960 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14961 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14962 macros related to unification of CJK characters. For the details,
14963 see the discussion following the message here:
14964 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

14980 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14982 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14983 position we get to after a call to move_it_to fails the
14984 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14985 only if we wind up in a string from display property. (Bug#11063)
14987 * window.c (Fdelete_other_windows_internal): Invalidate the row
14988 and column information about mouse highlight, so that redisplay
14989 restores it after reallocating the glyph matrices. (Bug#7464)
14991 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14992 string comes from a `display' text property, use the buffer
14993 position of that property as if we actually saw that position in
14995 (move_it_by_lines): Remove the assertion that
14996 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14997 violated when there's a before-string at the beginning of a line.

15019 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
15022 2012-03-26 Kenichi Handa <handa@m17n.org>
15024 * dispextern.h (struct glyph): Fix previous change. Change the
15025 bit length of glyphless.ch to 25 (Bug#11082).
15027 2012-03-26 Chong Yidong <cyd@gnu.org>
15029 * keyboard.c (Vselection_inhibit_update_commands): New variable.
15030 (command_loop_1): Use it; inhibit selection update for
15031 handle-select-window too (Bug#8996).
15033 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
15035 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
15037 2012-03-25 Kenichi Handa <handa@m17n.org>
15039 * dispextern.h (struct glyph): Change the bit length of
15040 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
15042 2012-03-24 Eli Zaretskii <eliz@gnu.org>
15044 * s/ms-w32.h (tzname): Include time.h before redirecting to
15045 _tzname. Fixes the MSVC build. (Bug#9960)
15047 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
15049 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
15052 * xterm.c (XTread_socket): Only modify handling_signal if
15053 !SYNC_INPUT. (Bug#11080)
15055 2012-03-23 Eli Zaretskii <eliz@gnu.org>
15057 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
15058 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
15059 when fetching a multibyte character consumes more bytes than
15060 CHAR_BYTES returns, due to unification of CJK characters in
15061 string_char. (Bug#11073)
15063 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
15065 * process.c (wait_reading_process_output): Handle pty disconnect
15066 by refraining from sending oneself a SIGCHLD (bug#10933).
15068 2012-03-22 Chong Yidong <cyd@gnu.org>

15072 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
15073 Mark string as coming from a prefix property.
15074 (handle_face_prop): Use default face for prefix strings (Bug#4281).
15075 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
15077 2012-03-21 Chong Yidong <cyd@gnu.org>
15079 * xfaces.c (Vface_remapping_alist): Doc fix.
15081 2012-03-20 Eli Zaretskii <eliz@gnu.org>
15083 * w32proc.c (Fw32_set_console_codepage)
15084 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
15087 2012-03-20 Chong Yidong <cyd@gnu.org>
15089 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
15090 to reflect default non-nil value of redisplay-dont-pause.
15092 2012-03-19 Kenichi Handa <handa@m17n.org>
15094 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
15095 it fit in a valid range (Bug#11003).
15097 2012-03-18 Eli Zaretskii <eliz@gnu.org>
15099 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
15100 that is not from display property, accept the row as a "cursor
15101 row" if one of the string's character has a non-nil `cursor'
15102 property. Fixes cursor positioning when there are newlines in
15103 overlay strings, e.g. in icomplete.el. (Bug#11035)
15105 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
15107 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
15109 2012-03-12 Chong Yidong <cyd@gnu.org>
15111 * eval.c (inhibit_lisp_code): Rename from
15112 inhibit_window_configuration_change_hook; move from window.c.
15114 * xfns.c (unwind_create_frame_1, Fx_create_frame):
15115 * window.c (run_window_configuration_change_hook)
15116 (syms_of_window): Callers changed.
15118 2012-03-11 Chong Yidong <cyd@gnu.org>
15120 * keymap.c (Fkey_description): Doc fix (Bug#9700).
15122 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
15124 2012-03-10 Chong Yidong <cyd@gnu.org>
15126 * frame.c (other_visible_frames): Don't assume the selected frame
15127 is visible (Bug#10955).
15129 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
15131 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

15135 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
15136 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
15139 2012-03-03 Glenn Morris <rgm@gnu.org>
15141 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
15143 2012-03-02 Eli Zaretskii <eliz@gnu.org>
15145 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
15146 position past the first glyph_row that ends at ZV. (Bug#10902)
15147 (redisplay_window, next_element_from_string): Fix typos in
15149 (redisplay_window): Pass to move_it_vertically the margin in
15150 pixels, not in screen lines.
15152 2012-03-02 Glenn Morris <rgm@gnu.org>
15154 * buffer.c (buffer-list-update-hook): Doc fix.
15156 2012-02-29 Eli Zaretskii <eliz@gnu.org>
15158 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
15159 push_it before setting up the iterator for the first overlay
15160 string, even if we have an empty string loaded.
15161 (next_overlay_string): If there's an empty string on the iterator
15162 stack, pop the stack. (Bug#10903)
15164 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
15166 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15167 Suggested by Stefan Monnier in
15168 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15169 * alloc.c (widen_to_Lisp_Object): New static function.
15170 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15171 and widening them to Lisp_Objects. This would work even if
15172 USE_LSB_TAG is defined and wide integers are used, which might
15173 happen in a future version of Emacs.
15175 2012-02-25 Chong Yidong <cyd@gnu.org>
15177 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
15180 * xselect.c (Fx_selection_exists_p): Doc fix.
15181 (x_clipboard_manager_save_all): Print an informative message
15182 before saving to clipboard manager.
15184 2012-02-24 Chong Yidong <cyd@gnu.org>
15186 * keyboard.c (process_special_events): Handle all X selection
15187 requests in kbd_buffer, not just the next one (Bug#8869).
15189 2012-02-23 Chong Yidong <cyd@gnu.org>
15191 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
15192 call when setting menu-bar-lines and tool-bar-lines parameters.
15193 (unwind_create_frame_1): New helper function.
15195 * window.c (inhibit_window_configuration_change_hook): New var.
15196 (run_window_configuration_change_hook): Obey it.
15197 (syms_of_window): Initialize it.
15199 2012-02-22 Chong Yidong <cyd@gnu.org>
15201 * xterm.c (x_draw_image_relief): Add missing type check for
15202 Vtool_bar_button_margin (Bug#10743).
15204 2012-02-21 Chong Yidong <cyd@gnu.org>
15206 * fileio.c (Vfile_name_handler_alist): Doc fix.
15208 * buffer.c (Fget_file_buffer): Protect against invalid file
15209 handler return value.
15211 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
15213 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
15214 when computing $valmask.
15216 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15217 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15218 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15219 It's useless in that case, and it can cause problems on hosts
15220 that allocate halves of EMACS_INT values separately.
15221 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15222 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15223 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15224 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15225 it avoids undefined behavior on hosts where shifting right by more
15226 than the word width has undefined behavior.
15228 2012-02-19 Chong Yidong <cyd@gnu.org>
15230 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15231 (Funhandled_file_name_directory, Ffile_name_as_directory)
15232 (Fdirectory_file_name, Fexpand_file_name)
15233 (Fsubstitute_in_file_name): Protect against invalid file handler
15234 return values (Bug#10845).
15236 2012-02-18 Eli Zaretskii <eliz@gnu.org>
15238 * .gdbinit (pitx): Fix incorrect references to fields of the

15248 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
15250 2012-02-15 Chong Yidong <cyd@gnu.org>
15252 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
15253 marked as special. Also, starting docstrings with * is obsolete.
15255 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
15257 * gnutls.c (emacs_gnutls_write): Fix last change.
15259 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

15266 * keymap.c (Fsingle_key_description): Handle char ranges.
15268 2012-02-12 Chong Yidong <cyd@gnu.org>
15270 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
15271 as that creates a dangerous corner case.
15273 * window.c (Fdelete_window_internal): Invalidate the mouse
15274 highlight (Bug#9904).
15276 2012-02-12 Glenn Morris <rgm@gnu.org>

15279 (Fx_get_selection_internal, Fx_disown_selection_internal)
15280 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
15281 * nsselect.m (Fx_own_selection_internal)
15282 (Fx_disown_selection_internal, Fx_selection_exists_p)
15283 (Fx_selection_owner_p, Fx_get_selection_internal):
15284 Sync docs and argument specs with the xselect.c versions.
15286 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
15288 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
15290 2012-02-11 Eli Zaretskii <eliz@gnu.org>
15292 * w32select.c (Fx_selection_exists_p): Sync doc string and
15293 argument list with xselect.c. (Bug#10783)
15295 * w16select.c (Fx_selection_exists_p): Sync doc string and
15296 argument list with xselect.c. (Bug#10783)

15306 2012-02-07 Chong Yidong <cyd@gnu.org>
15308 * buffer.c (Fbuffer_local_variables)
15309 (buffer_lisp_local_variables): Handle unbound vars correctly;
15310 don't let Qunbound leak into Lisp.
15312 2012-02-07 Glenn Morris <rgm@gnu.org>
15314 * image.c (Fimagemagick_types): Doc fix.
15316 * image.c (imagemagick-render-type): Change it from a lisp object
15317 to an integer. Move the doc here from the lisp manual.
15318 Treat all values not equal to 0 the same.
15320 2012-02-06 Chong Yidong <cyd@gnu.org>
15322 * doc.c (store_function_docstring): Avoid applying docstring of
15323 alias to base function (Bug#2603).
15325 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
15327 * .gdbinit (pp1, pv1): Remove redundant defines.
15330 2012-02-04 Chong Yidong <cyd@gnu.org>
15332 * nsterm.m: Declare a global (Bug#10694).
15334 2012-02-04 Eli Zaretskii <eliz@gnu.org>
15336 * w32.c (get_emacs_configuration_options):
15337 Include --enable-checking, if specified, in the return value.
15339 2012-02-04 Martin Rudalics <rudalics@gmx.at>
15341 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
15342 after rounding frame sizes. (Bug#9723)

15346 * keyboard.c (adjust_point_for_property): Don't position point
15347 before BEGV. (Bug#10696)
15349 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
15351 Handle overflow when computing char display width (Bug#9496).
15352 * character.c (char_width): Return EMACS_INT, not int.
15353 (char_width, c_string_width): Check for overflow when
15354 computing the width; this is possible now that individual
15355 characters can have unbounded width. Problem introduced
15356 by merge from Emacs 23 on 2012-01-19.
15358 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
15360 * dbusbind.c (Fdbus_register_method): Mention the return value
15361 :ignore in the docstring.
15363 2012-02-02 Glenn Morris <rgm@gnu.org>
15365 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

15373 2012-02-02 Kenichi Handa <handa@m17n.org>
15375 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
15376 0, do not call append_composite_glyph.
15378 2012-02-02 Kenichi Handa <handa@m17n.org>
15380 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
15382 (x_produce_glyphs): If the component of a composition is a null
15383 string, set it->pixel_width to 1 to avoid zero-width glyph.
15385 2012-02-01 Eli Zaretskii <eliz@gnu.org>
15387 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15388 first 2 arguments are identical. This makes inserting large
15389 output from a subprocess an order of magnitude faster on
15390 MS-Windows, where all sbrk'ed memory is always contiguous.
15392 2012-01-31 Glenn Morris <rgm@gnu.org>
15394 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

15430 2012-01-21 Chong Yidong <cyd@gnu.org>
15432 * floatfns.c (Fcopysign): Make the second argument non-optional,
15433 since nil is not allowed anyway.
15435 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
15437 * process.c (read_process_output): Use p instead of XPROCESS (proc).

15440 2012-01-19 Martin Rudalics <rudalics@gmx.at>
15442 * window.c (save_window_save, Fcurrent_window_configuration)
15443 (Vwindow_persistent_parameters): Do not use Qstate.
15444 Rewrite doc-strings.
15446 2012-01-19 Kenichi Handa <handa@m17n.org>
15448 * character.c (char_width): New function.
15449 (Fchar_width, c_string_width, lisp_string_width):
15450 Use char_width (Bug#9496).

15455 (Fset_window_configuration, save_window_save): Handle persistent
15458 2012-01-14 Eli Zaretskii <eliz@gnu.org>
15460 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
15461 thrashing the stack of the thread. (Bug#9087)
15463 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
15465 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.
15467 2012-01-11 Eli Zaretskii <eliz@gnu.org>

15470 highlight ends on a newline. (Bug#10464)
15471 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
15472 he end column for display of highlight that ends on a newline
15475 2012-01-11 Glenn Morris <rgm@gnu.org>
15477 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
15478 from load-path also when installation-directory is nil. (Bug#10208)
15480 2012-01-10 Glenn Morris <rgm@gnu.org>
15482 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
15484 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
15485 Update template values to be closer to their typical values these days.
15487 2012-01-09 Eli Zaretskii <eliz@gnu.org>
15489 * xdisp.c (rows_from_pos_range): Accept additional argument
15490 DISP_STRING, and accept any glyph in a row whose object is that
15491 string as eligible for mouse highlight. Fixes mouse highlight of
15492 display strings from overlays. (Bug#10464)
15494 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
15496 emacs: fix an auto-save permissions race condition (Bug#10400)
15497 * fileio.c (auto_saving_dir_umask): New static var.
15498 (Fmake_directory_internal): Use it.
15499 (do_auto_save_make_dir): Set it, instead of invoking chmod after
15500 creating the directory. The old code temporarily assigns
15501 too-generous permissions to the directory.
15502 (do_auto_save_eh): Clear it.
15503 (Fdo_auto_save): Catch all errors, not just file errors, so
15504 that the var is always cleared.

16005 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
16006 Otherwise, valgrind does not work on some platforms.
16007 Problem reported by Andreas Schwab in
16008 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
16009 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
16010 is set, removing the need for VIRT_ADDRESS_VARIES.
16011 (PURE_P): Use a more-efficient implementation that needs just one
16012 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
16013 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
16014 to 4 (xorl, subq, cmpq, setbe).
16015 * alloc.c (pure): Always extern now, since that's the
16016 VIRT_ADDR_VARIES behavior.
16017 (PURE_POINTER_P): Use a single comparison, not two, for
16018 consistency with the new puresize.h.
16019 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
16020 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
16021 Remove VIRT_ADDR_VARIES no longer needed.

16026 (erase_phys_cursor, update_window_cursor, show_mouse_face)
16027 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
16028 behave as if the cursor position were at the window margin.
16030 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
16031 and the cursor position is out of bounds, behave as if the cursor
16032 position were at the window margin. (Bug#10075)
16034 2011-11-18 Chong Yidong <cyd@gnu.org>
16036 * window.c (Fwindow_combination_limit): Make first argument

16054 hash values of the two rows. (Bug#10035)
16055 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
16057 * xdisp.c (row_hash): New function, body extracted from
16058 compute_line_metrics.
16059 (compute_line_metrics): Call row_hash, instead of computing the
16062 * dispnew.c (verify_row_hash): Call row_hash for computing the
16063 hash code of a row, instead of duplicating code from xdisp.c.
16065 * dispextern.h (row_hash): Add prototype.
16067 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

16094 (recombine_windows, make_parent_window, make_window)
16095 (Fsplit_window_internal, saved_window)
16096 (Fset_window_configuration, save_window_save): Rename all
16097 occurrences of window_nest to window_combination_limit.

16103 2011-11-14 Eli Zaretskii <eliz@gnu.org>
16105 * xdisp.c (display_line): Move the call to
16106 highlight_trailing_whitespace before the call to
16107 compute_line_metrics, since the latter needs to see the final
16108 faces of all the glyphs to compute ROW's hash value.
16109 Fixes assertion violations in row_equal_p. (Bug#10035)
16111 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
16113 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
16114 just return (bug#10044).
16116 2011-11-12 Eli Zaretskii <eliz@gnu.org>
16118 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
16119 with user-defined heap size. Bump the default size of the temacs
16120 heap to 27MB, to avoid memory warning when running temacs.
16121 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
16123 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
16124 current_matrix and desired_matrix. (Bug#9990)
16125 (verify_row_hash) [XASSERTS]: New function.

16170 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
16172 Avoid some portability problems by eschewing 'extern inline' functions.
16173 The trivial performance wins aren't worth the portability hassles; see
16174 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
16176 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

16242 * xmenu.c (cleanup_widget_value_tree): New function.
16243 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
16244 calling free_menubar_widget_value_tree directly (Bug#9830).

16250 (window_box_width, window_box_left, window_box_left_offset)
16251 (window_box_right, window_box_right_offset): Declare extern.
16252 Otherwise, these inline functions do not conform to C99 and
16253 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
16254 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
16255 * intervals.c (adjust_intervals_for_insertion)

16258 (static_offset_intervals): Remove.
16259 (offset_intervals): Rewrite using the old contents of
16260 static_offset_intervals. The old version didn't conform to C99
16261 because an extern inline function contained a reference to an
16262 identifier with static linkage.

16315 (unwind_create_frame): New function (Bug#9943).
16316 (Fx_create_frame): Restructure code to be more similar to the one in
16317 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

16328 official. Move initialization of image_cache_refcount and
16329 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

16428 (x_handle_net_wm_state): Return what get_current_wm_state returns.
16429 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
16431 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
16433 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
16434 so that this new function doesn't get optimized away by a
16435 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
16437 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
16439 * frame.h (MOUSE_HL_INFO): Remove excess parens.
16441 2011-10-29 Eli Zaretskii <eliz@gnu.org>
16443 Fix the `xbytecode' command.
16444 * .gdbinit (xprintbytestr): New command.
16445 (xwhichsymbols): Rename from `which'; all callers changed.
16446 (xbytecode): Print the byte-code string as well.
16448 2011-10-29 Kim Storm <storm@cua.dk>
16450 * alloc.c (which_symbols): New function.
16452 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
16454 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
16457 2011-10-29 Glenn Morris <rgm@gnu.org>
16459 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
16460 Not clear what it was for, and it causes various bugs. (Bug#9839)
16462 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16464 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
16465 possible random value that matches one of those tested as
16466 condition to clear the mouse face.
16468 2011-10-28 Chong Yidong <cyd@gnu.org>
16470 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
16472 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
16474 * window.c (make_window): Initialize phys_cursor_on_p.
16476 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
16478 * lisp.h (struct Lisp_Symbol): Update comments.
16480 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
16482 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
16484 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16486 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
16487 <oslsachem@gmail.com> for helping to debug this.
16489 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
16490 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
16491 (g_b_init_get_glyph_outline_w): New static variables.
16492 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
16493 (GetGlyphOutlineW_Proc): New typedefs.
16494 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
16495 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
16497 (w32font_open_internal, compute_metrics):
16498 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16499 instead of calling the "wide" APIs directly.
16501 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
16503 * w32.h (syms_of_w32font): Add prototype.
16505 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16507 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
16508 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
16509 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
16510 (Fmove_to_window_line): Doc fix.
16512 2011-10-27 Chong Yidong <cyd@gnu.org>
16514 * process.c (make_process): Set gnutls_state to NULL.
16516 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
16517 non-NULL, regardless of GNUTLS_INITSTAGE.
16518 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
16519 an error. Set process slots as soon as we allocate them.
16521 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
16523 2011-10-27 Chong Yidong <cyd@gnu.org>
16525 * gnutls.c (emacs_gnutls_deinit): New function.
16526 Deallocate credentials structures as well as calling gnutls_deinit.
16527 (Fgnutls_deinit, Fgnutls_boot): Use it.
16529 * process.c (make_process): Initialize GnuTLS credentials to NULL.
16530 (deactivate_process): Call emacs_gnutls_deinit.
16532 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16534 * image.c (x_create_x_image_and_pixmap):
16535 * w32.c (sys_rename, w32_delayed_load):
16536 * w32font.c (fill_in_logfont):
16537 * w32reg.c (x_get_string_resource): Silence compiler warnings.
16539 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
16541 * w32fns.c (w32_default_color_map): New function,
16542 extracted from Fw32_default_color_map.
16543 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
16545 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
16547 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
16549 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
16551 * keyboard.c (test_undefined): New function (bug#9751).
16552 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
16554 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
16556 * sysdep.c (init_sys_modes): Fix the check for the controlling
16557 terminal (Bug#6649).
16559 2011-10-20 Eli Zaretskii <eliz@gnu.org>
16561 * dispextern.h (struct bidi_it): New member next_en_type.
16563 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16564 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16565 current character, check also for next_en_type being WEAK_EN.
16566 (bidi_resolve_weak): Don't enter the expensive loop if the current
16567 position is before next_en_pos. Record the bidi type of the first
16568 non-ET, non-BN character we find, in addition to its position.
16569 (bidi_level_of_next_char): Invalidate next_en_type when
16570 next_en_pos is over-stepped.
16572 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16574 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16575 * editfns.c: Rewrite current-time-zone so that it invokes
16576 the equivalent of (format-time-string "%Z") to get the time zone name.
16577 This fixes a bug when the time zone name contains characters that
16578 need converting from the system time locale to Emacs internal format.
16579 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16580 that patch fixed format-time-string to do the conversion, but
16581 I forgot to fix current-time-zone.
16582 (format_time_string): New function, containing most of
16583 what Fformat_time_string used to contain.
16584 (Fformat_time_string): Rewrite in terms of format_time_string.
16585 This doesn't change this function's behavior.
16586 (current-time-zone): Rewrite to use format_time_string.
16587 This fixes the bug reported by Michael Schierl in
16588 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16589 Jason Rumney's 2007-06-07 change worked around this bug, but
16591 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16593 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16595 * xdisp.c (start_display): If the character at POS is displayed
16596 via a display vector, reset IT->current.dpvec_index to zero.
16597 (try_window_reusing_current_matrix): If a line ends in a display
16598 vector or the next line starts in a display vector, continue
16599 redrawing the window even though the character position of
16600 start_row was reached.
16603 2011-10-18 Chong Yidong <cyd@gnu.org>
16605 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16606 with nobreak-char-display too.
16608 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16610 Fix part 3 of bug#9771.
16611 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16612 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16613 non-neutral characters if the current character is a paragraph
16614 separator (a.k.a. Newline). This avoids running the same
16615 expensive loop twice, once when we consume the preceding newline
16616 and the other time when the line actually needs to be displayed.
16617 Avoid the loop when we see neutrals on the base embedding level
16618 following a character whose directionality is the same as the
16619 paragraph's. This avoids running the expensive loop when a line
16620 ends in a long sequence of neutrals, like control characters.
16621 Add assertion against STRONG_AL type. Slightly rearrange code
16622 that determines the type of a neutral given the first non-neutral
16624 (bidi_level_of_next_char): Set next_en_pos to zero when
16625 invalidating its info.
16627 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16629 * xdisp.c (push_display_prop): Determine whether to record string
16630 or buffer position by IT->string, not by IT->method. Allow
16631 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16632 (move_it_vertically_backward): Don't look for character position
16633 immediately after the newline when in a continuation line.
16636 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16638 * window.c (coordinates_in_window): Rewrite and delabelize
16639 vertical border check. (Bug#5357) (Bug#9618)
16641 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16643 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16644 errors in XSetWindowBorder (bug#9310).
16646 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16648 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16649 avoid crash when xmalloc overrun checking is enabled.
16651 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16653 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16654 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16655 cursor motion with <left> and <right> arrow keys.
16657 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16658 some callers set that themselves.
16660 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16662 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16663 display string and the previous row comes from the same string and
16664 is empty. (Bug#9739) (Bug#9738)
16666 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16668 * doc.c (get_doc_string): Encode file name (bug#9735).
16670 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16672 * bidi.c (bidi_level_of_next_char):
16673 * xdisp.c (get_visually_first_element): Remove old incorrect
16674 comments regarding the Unicode Line Separator character.
16676 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16678 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16680 * alloc.c (Fgc_status): Do not access beyond zombies array
16681 boundary if nzombies > MAX_ZOMBIES.
16682 * alloc.c (dump_zombies): Add missing format specifier.
16684 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16686 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16687 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16689 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16690 Some packages use them to denote characters with modifiers.
16692 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16694 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16695 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16696 matching a pp-number. Rename parameter var to var1.
16698 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16700 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16702 2011-10-08 Glenn Morris <rgm@gnu.org>
16704 * callint.c (Fcall_interactively): Give a more explicit error for the
16705 'c' case with a non-character input. (Bug#8479)
16707 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16709 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16711 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16712 lines that are hscrolled on the left.
16714 * dispnew.c (buffer_posn_from_coords): Account for a possible
16715 presence of header-line. (Bug#4426)
16717 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16719 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16720 Don't advertise functionality which we discourage or doesn't work.
16722 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16724 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16725 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16726 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16727 this makes Emacs dump core during garbage collection on rare
16728 occasions. sizeof is obviously inferior to offsetof here, so
16729 stick with offsetof.
16730 (GC_POINTER_ALIGNMENT): New macro.
16731 (mark_memory): Omit 3rd (offset) arg; caller changed.
16732 Don't assume EMACS_INT alignment is the same as pointer alignment.
16734 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16736 * keyboard.c (read_key_sequence_remapped): New var.
16737 (read_key_sequence): Compute remapping in the right buffer.
16738 (command_loop_1): Use read_key_sequence's remapping directly.
16740 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16742 * dired.c (file_name_completion): Don't expand file name.
16743 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16744 before checking file name handler.
16746 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16747 they've been requested explicitly (bug#9591).
16749 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16751 * keymap.c (Fsingle_key_description): Use make_specified_string
16752 instead of build_string to build string from push_key_description.
16755 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16757 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16758 This fixes a Y2038 bug on 64-bit hosts.
16759 * buffer.c (reset_buffer):
16760 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16761 (Fclear_buffer_auto_save_failure):
16762 Use 0, not -1, to represent an unset failure time, since time_t
16763 might not be signed.
16765 Remove dependency on glibc malloc internals.
16766 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16767 Move back here from lisp.h, but with their new implementations.
16768 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16769 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16770 * charset.c (charset_table_init): New static var.
16771 (syms_of_charset): Use it instead of xmalloc. This removes a
16772 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16773 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16774 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16775 Move back to alloc.c.
16776 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16777 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16779 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16781 * nsterm.m (windowDidResize): Call x_set_window_size only when
16782 ns_in_resize is true. Otherwise set pixelwidth/height and
16783 call change_frame_size (Bug#9628).
16785 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16787 Port --enable-checking=all to Fedora 14 x86-64.
16788 * charset.c (syms_of_charset): Also account for glibc malloc's
16789 internal overhead when calculating the initial malloc maximum.
16791 Port --enable-checking=all to Fedora 14 x86.
16792 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16794 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16795 (overrun_check_realloc, overrun_check_free):
16796 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16797 That way, xmalloc returns a properly-aligned pointer even if
16798 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16799 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16800 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16801 into account when calculating the initial malloc maximum.
16802 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16803 Move here from alloc.c, so that charset.c can use it too.
16804 Properly align; the old code wasn't right for common 32-bit hosts
16805 when configured with --enable-checking=all.
16806 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16807 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16809 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16811 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16814 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16816 * xdisp.c (compute_display_string_end): If there's no display
16817 string at CHARPOS, return -1.
16819 * bidi.c (bidi_fetch_char): When compute_display_string_end
16820 returns a negative value, treat the character as a normal
16821 character not covered by a display string. (Bug#9624)
16823 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16825 * lread.c (Fread_from_string): Fix typo in docstring.
16827 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16829 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16830 newline, reseat the iterator instead of bidi-iterating there one
16831 character at a time. (Bug#9610)
16832 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16833 TO_CHARPOS if the bidi iterator is at base embedding level.
16835 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16837 * lread.c (readevalloop): Use correct code for NBSP.
16838 (read1): Likewise. (Bug#9608)
16840 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16842 * dbusbind.c (Fdbus_register_signal): When service is not
16843 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16845 2011-09-25 Glenn Morris <rgm@gnu.org>
16847 * buffer.c (truncate-lines): Doc fix.
16849 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16851 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16852 (Fset_window_next_buffers): Doc fix.
16854 2011-09-24 Glenn Morris <rgm@gnu.org>
16856 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16858 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16860 Fix minor problems found by static checking.
16861 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16862 * indent.c (Fvertical_motion): Fix == vs = typo.
16864 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16866 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16867 Default value is now t. Doc fix.
16869 * indent.c (Fvertical_motion): Compute and apply the overshoot
16870 logic when moving up, not only when moving down. Fix the
16871 confusing name and values of the it_overshoot_expected variable;
16872 logic changes accordingly. (Bug#9254) (Bug#9549)
16874 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16875 CHARPOS is covered by a display string which includes newlines.
16876 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16877 is covered by a display string with embedded newlines.
16879 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16881 * dbusbind.c (Fdbus_register_signal): Add match rule to
16882 Vdbus_registered_objects_table. (Bug#9581)
16883 (Fdbus_register_method, Vdbus_registered_objects_table):
16886 2011-09-24 Jim Meyering <meyering@redhat.com>
16888 do not ignore write error for any output size
16889 The previous change was incomplete.
16890 While it makes emacs --batch detect the vast majority of stdout
16891 write failures, errors were still ignored whenever the output size is
16892 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16893 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16894 && echo FAIL: ignored write error
16895 FAIL: ignored write error
16896 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16897 && echo FAIL: ignored write error
16898 FAIL: ignored write error
16899 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16901 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16903 * emacs.c (Fkill_emacs): In noninteractive mode exit
16904 non-successfully if a write error occurred on stdout. (Bug#9574)

16908 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16911 * dispextern.h (struct it): Update the comment documenting what
16914 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16916 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16917 a display string, extend search for cursor position to end of row.
16918 (find_row_edges): If the row ends in a newline from a display
16919 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16920 Handle the case of a display string with multiple newlines.
16921 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16922 non-empty line. Fixes confusing cursor motion with arrow keys at
16923 the beginning of a line that starts with whitespace.
16925 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16927 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16930 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16932 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16933 boolean (Bug#9154).
16935 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16937 * xdisp.c (display_line): Record maximum and minimum buffer
16938 positions even if no glyphs were produced (e.g., by a zero-width
16939 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16940 buffer positions that will be removed from the glyph row because
16942 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16943 column is beyond frame width: don't subtract 1 "pixel" when
16944 computing width of the stretch.
16945 (reseat_at_next_visible_line_start): Undo the change made on
16946 2011-09-17 that saved paragraph information and restored it after
16947 the call to `reseat'. (Bug#9545)
16949 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16951 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16952 and turn window cursor on if cleared (Bug#9415).
16954 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16956 * search.c (boyer_moore): Take unibyte characters from pattern
16957 literally. (Bug#9458)
16959 2011-09-18 Eli Zaretskii <eliz@gnu.org>

16963 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16965 Fix minor problem found by static checking.

16967 initialized, to pacify gcc -Wuninitialized.
16969 * fileio.c: Report proper errno when syscall falls.
16970 (Finsert_file_contents): Save and restore errno,
16971 so that report_file_error outputs the correct diagnostic.
16972 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16974 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16976 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16978 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16980 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16981 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16983 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16985 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16986 about the current paragraph and restore it after the call to reseat.
16988 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16989 (bidi_find_paragraph_start): Search back for paragraph beginning
16990 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16991 (bidi_move_to_visually_next): Only trigger paragraph-related
16992 computations when the last character is a newline or at EOB, not
16993 just any NEUTRAL_B. (Bug#9470)
16995 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16996 truncated lines if point is covered by a display string. (Bug#9524)
16998 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
17000 * xselect.c: Relax test for outgoing X longs (Bug#9498).
17001 (cons_to_x_long): New function.
17002 (lisp_data_to_selection_data): Use it. Correct the test for
17003 short-versus-long data; it was negated. Break out of vector
17004 loop, for efficiency, when a long datum is discovered.
17006 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
17008 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
17010 2011-09-16 Eli Zaretskii <eliz@gnu.org>
17012 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
17013 GCC PR/17406) by declaring this function with external scope.
17015 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
17017 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
17018 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
17020 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
17022 * editfns.c (Fformat): Correctly handle text properties on "%%".

17030 * xdisp.c (get_next_display_element)
17031 (fill_composite_glyph_string): Add comments about special meaning
17032 of TAB characters in a composition.
17034 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
17036 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
17037 This occurs when processing a multibyte format.
17038 Problem reported by Wolfgang Jenker.
17040 2011-09-15 Johan Bockgård <bojohan@gnu.org>
17042 * xdisp.c (try_cursor_movement): Only check for exact match if
17043 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
17045 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
17047 Remove unused external symbols.
17048 * dispextern.h (calc_pixel_width_or_height): Remove decl.
17049 * xdisp.c (calc_pixel_width_or_height): Now static.
17050 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
17051 * indent.c (check_display_width):
17052 * w32term.c: Fix comment to match code.
17053 * xterm.c, xterm.h (x_catching_errors): Remove.
17055 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
17057 * xselect.c: Use signed conversions more consistently (Bug#9498).
17058 (selection_data_to_lisp_data): Assume incoming selection data are
17059 signed integers, not unsigned. This is to be consistent with
17060 outgoing selection data, which was modified to use signed integers
17061 in as part of the fix to Bug#9196 in response to Jan D.'s comment
17062 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
17063 expects long, not unsigned long.
17065 2011-09-14 Eli Zaretskii <eliz@gnu.org>
17067 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
17068 computation of loop end. Reported by Johan Bockgård
17071 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
17073 * frame.c (Fother_visible_frames_p): Function deleted.
17075 2011-09-12 Eli Zaretskii <eliz@gnu.org>
17077 * indent.c (compute_motion): Process display vector front to back
17078 rather than the other way around. (Bug#2496)
17080 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
17082 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
17084 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
17086 * minibuf.c (Fread_from_minibuffer): Doc fix.
17088 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17090 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
17091 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
17093 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
17095 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
17096 value for non-existent files.
17098 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17100 * fileio.c (Finsert_file_contents): If the file cannot be opened,
17101 set its "size" to -1. This will set the modtime_size field of
17102 the corresponding buffer to -1, which is what
17103 verify-visited-file-modtime expects for files that do not exist.
17106 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
17108 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
17110 * lisp.h: ... from here. push_key_description is no longer
17111 defined in keyboard.c, so its declaration should not be in
17112 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
17113 logically belongs with push_key_description.
17115 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
17117 * buffer.h: Include <sys/types.h> instead of <time.h>.
17118 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
17119 Problem reported by Herbert J. Skuhra.
17121 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
17123 * xml.c (parse_region): Make the parsing work for
17124 non-comment-starting XML files again (bug#9144).
17126 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
17128 * image.c (gif_load): Fix calculation of bottom and right corner.
17131 2011-09-10 Eli Zaretskii <eliz@gnu.org>
17133 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
17134 redisplay in small windows.
17136 2011-09-09 Eli Zaretskii <eliz@gnu.org>
17138 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
17140 2011-09-08 Martin Rudalics <rudalics@gmx.at>
17142 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
17143 Operate on live windows only.
17145 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
17147 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
17149 2011-09-07 Eli Zaretskii <eliz@gnu.org>
17151 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
17152 only under bidi iteration.
17154 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17156 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17158 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17160 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17161 Without this fix, the command to link temacs failed due to an
17162 undefined symbol __builtin_isnan. This is because
17163 /usr/include/iso/math_c99.h #defines isnan(x) to
17164 __builtin_isnan(x), but the bundled gcc, which identifies itself
17165 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17167 * floatfns.c (isnan): #undef, and then #define to a clone of
17169 (Fisnan): Always define, since it's always available now.
17170 (syms_of_floatfns): Always define isnan at the Lisp level.
17172 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17174 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17176 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17178 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17179 The previous code assumed that file offsets (off_t values) fit in
17180 EMACS_INT variables, which is not true on typical 32-bit hosts.
17181 The code messed up by falsely reporting buffer overflow in cases
17182 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17183 when "big" contains more than 2**29 bytes, even though this
17184 inserts just one byte and does not overflow the buffer.
17185 (Finsert_file_contents): Store file offsets as off_t
17186 values, not as EMACS_INT values. Check for overflow when
17187 converting between EMACS_INT and off_t. When checking for
17188 buffer overflow or for overlap, take the offsets into account.
17189 Don't use EMACS_INT for small values where int suffices.
17190 When checking for overlap, fix a typo: ZV was used where
17191 ZV_BYTE was intended.
17192 (Fwrite_region): Don't assume off_t fits into 'long'.
17193 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17195 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17197 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17199 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17201 sprintf-related integer and memory overflow issues (Bug#9412).
17203 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17204 (esprintf, exprintf, evxprintf): New functions.
17205 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17206 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17207 (modify_event_symbol): Do not assume that the length of
17208 name_alist_or_stem is safe to alloca and fits in int.
17209 (Fexecute_extended_command): Likewise for function name and binding.
17210 (Frecursion_depth): Wrap around reliably on integer overflow.
17211 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17212 since some callers pass EMACS_INT values.
17213 (Fsingle_key_description): Don't crash if symbol name contains more
17214 than MAX_ALLOCA bytes.
17215 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17216 (get_minibuffer): Arg is now EMACS_INT, not int.
17217 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17218 (esprintf, exprintf, evxprintf): New decls.
17219 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17221 * dbusbind.c (signature_cat): New function.
17222 (xd_signature, Fdbus_register_signal):
17223 Do not overrun buffer; instead, report string overflow.
17225 * dispnew.c (add_window_display_history): Don't overrun buffer.
17226 Truncate instead; this is OK since it's just a log.
17228 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17229 even if the time zone offset is outlandishly large.
17230 Don't mishandle offset == INT_MIN.
17232 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17233 when creating daemon; the previous buffer-overflow check was incorrect.
17235 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17236 which has the guts of the old verror function.
17238 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17239 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17241 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17242 (font_unparse_xlfd): Don't blindly alloca long strings.
17243 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17244 fits in int, when using sprintf. Use single snprintf to count
17245 length of string rather than counting it via multiple sprintfs;
17246 that's simpler and more reliable.
17247 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17248 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17249 sprintf, in case result does not fit in int.
17251 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17252 (fontset_from_font): Print it.
17254 * frame.c (tty_frame_count): Now printmax_t, not int.
17255 (make_terminal_frame, set_term_frame_name): Print it.
17256 (x_report_frame_params): In X, window IDs are unsigned long,
17257 not signed long, so print them as unsigned.
17258 (validate_x_resource_name): Check for implausibly long names,
17259 and don't assume name length fits in 'int'.
17260 (x_get_resource_string): Don't blindly alloca invocation name;
17261 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17264 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17265 (xg_check_special_colors, xg_set_geometry):
17266 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17268 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17269 Use esprintf, not sprintf, in case result does not fit in int.
17271 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17272 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17273 it as a large positive number.
17274 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17275 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17277 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17278 in case result does not fit in int.
17280 * print.c (float_to_string): Detect width overflow more reliably.
17281 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17282 buffer overrun. Don't assume list length fits in 'int'. Treat
17283 print length of 0 as 0, not as infinity; to be consistent with other
17284 uses of print length in this function. Don't overflow print length
17285 index. Don't assume hash table size fits in 'long', or that
17286 vectorlike size fits in 'unsigned long'.
17288 * process.c (make_process): Use printmax_t, not int, to format
17289 process-name gensyms.
17291 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17293 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17294 to avoid potential buffer overrun.
17296 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17297 if X resource line is longer than 512 bytes.
17299 * xfns.c (x_window): Make sprintf buffer a bit bigger
17300 to avoid potential buffer overrun.
17302 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17304 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17306 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17308 Integer overflow fixes for scrolling, etc.
17309 Without these, Emacs silently mishandles large integers sometimes.
17310 For example, "C-u 4294967297 M-x recenter" was treated as if
17311 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17313 * xdisp.c (try_window_id): Check Emacs fixnum range before
17314 converting to 'int'.
17316 * window.c (window_scroll_line_based, Frecenter):
17317 Check that an Emacs fixnum is in range before assigning it to 'int'.
17318 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17319 values converted from Emacs fixnums.
17320 (Frecenter): Don't wrap around a line count if it is out of 'int'
17321 range; instead, treat it as an extreme value.
17322 (Fset_window_configuration, compare_window_configurations):
17323 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17325 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17326 that can exceed INT_MAX. Check that EMACS_INT value is in range
17327 before assigning it to the (possibly-narrower) index.
17328 (match_limit): Don't assume that a fixnum can fit in 'int'.
17330 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17333 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17334 (Fvertical_motion): Don't wrap around LINES values that don't fit
17335 in 'int'. Instead, treat them as extreme values. This is good
17336 enough for windows, which can't have more than INT_MAX lines anyway.
17338 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17340 * Require libxml/parser.h to avoid compilation warning.
17342 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17344 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17345 since this reportedly can destroy thread storage.
17347 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17349 * syntax.c (find_defun_start): Update all cache variables if
17350 exiting early (Bug#9401).
17352 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17354 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17356 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17357 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17358 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17360 * term.c (tty_append_glyph): New function.
17361 (produce_stretch_glyph): Static function and its prototype deleted.
17363 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17366 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17368 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17369 when checking :margin (Bug#9390).
17370 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17371 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17372 so that the name doesn't mislead. All uses changed.
17374 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17376 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

17384 the first character in the line after the newline.
17386 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17388 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17389 (ccl_driver): Do not generate an out-of-range pointer.
17390 (Fccl_execute_on_string): Remove unnecessary check for
17391 integer overflow, noted by Stefan Monnier in
17392 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17393 Remove a FIXME that didn't need fixing.
17394 Simplify the newly-introduced buffer reallocation code.
17396 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17398 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17400 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17402 Integer and memory overflow issues (Bug#9196).
17404 * doc.c (get_doc_string): Rework so that
17405 get_doc_string_buffer_size is the actual buffer size, rather than
17406 being 1 less than the actual buffer size; this makes xpalloc more
17409 * image.c (x_allocate_bitmap_record, cache_image):
17410 * xselect.c (Fx_register_dnd_atom):
17411 Simplify previous changes by using xpalloc.
17413 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17414 since either will do and ptrdiff_t is convenient with xpalloc.
17416 * charset.c (charset_table_size)
17417 (struct charset_sort_data.priority): Now ptrdiff_t.
17418 (charset_compare): Don't overflow if priorities differ greatly.
17419 (Fsort_charsets): Don't assume list length fits in int.
17420 Check for size-calculation overflow when allocating sort data.
17421 (syms_of_charset): Allocate an initial charset table that is
17422 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17424 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17426 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17427 The actual value is always <= INT_MAX, and leaving it unsigned made
17428 overflow checking harder.
17430 * dispextern.h (struct glyph_matrix.rows_allocated)
17431 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17432 with xpalloc. The values are still always <= INT_MAX.
17434 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17436 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17437 (SAFE_NALLOCA): New macro.
17439 * region-cache.c (struct boundary.pos, find_cache_boundary)
17440 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17441 (set_cache_region, invalidate_region_cache)
17442 (revalidate_region_cache, know_region_cache, region_cache_forward)
17443 (region_cache_backward, pp_cache):
17444 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17445 so that ptrdiff_t * can be passed to xpalloc.
17446 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17447 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17448 (pp_cache): Don't assume cache_len fits in int.
17449 * region-cache.h: Adjust extern decls to match.
17451 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17452 EMACS_INT, since either will do, for xpalloc.
17454 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17455 (xnmalloc, xnrealloc, xpalloc): New functions.
17457 * bidi.c (bidi_shelve_header_size): New constant.
17458 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17459 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17461 * bidi.c (bidi_cache_shrink):
17462 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17464 Don't update size of array until after memory allocation succeeds,
17465 because xmalloc/xrealloc may not return.
17466 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17467 now that we have proper integer overflow checking.
17468 (record_overlay_string, overlay_strings): Catch overflows when
17469 calculating size of overlay_str_buf.
17471 * callproc.c (Fcall_process): Check for size overflow when
17472 calculating size of args2.
17473 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17474 Normally we prefer signed values, but sticking with ptrdiff_t would
17475 require adding more-complicated checks.
17477 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17478 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17479 Redo buffer-overflow calculations to avoid integer overflow.
17480 Add a FIXME comment where memory seems to be over-allocated.
17482 * character.c (Fstring): Check for size-calculation overflow.
17484 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17485 unnecessary integer overflow. Check for size overflow.
17486 (encode_coding_object): Don't update size until xmalloc succeeds.
17488 * composite.c (get_composition_id): Check for overflow in glyph
17489 length calculations.
17491 Integer and memory overflow fixes for display code.
17492 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17493 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
17494 (scrolling_window): Check for overflow in size calculations.

17506 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
17507 (get_doc_string): Check for size calculation overflow.
17508 Don't update size until allocation succeeds.
17509 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
17510 EMACS_INT, where ptrdiff_t will do.
17511 (Fsubstitute_command_keys): Check for string overflow.

17515 (message_length): Now ptrdiff_t, not int.
17516 (Fmessage_box): Don't update size until allocation succeeds.
17517 Don't assume message length fits in int.
17518 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17520 * emacs.c (main): Do not reallocate argv, since there is a null at
17521 the end that can be overwritten, and this way there's no need to
17522 worry about size-calculation overflow.
17523 (sort_args): Check for size-calculation overflow.
17525 * eval.c (init_eval_once, grow_specpdl): Don't update size until
17527 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
17529 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
17530 (x_set_scroll_bar_width, x_figure_window_size):
17531 Check for integer overflow.
17532 (x_set_alpha): Do not assume XINT fits in int.
17534 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17535 This is for the members text_lines, text_cols, total_lines, total_cols,
17536 where the system imposes an 'int' limit.
17538 * fringe.c (Fdefine_fringe_bitmap):
17539 Don't update size until alloc works.
17541 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
17542 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
17544 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
17545 Check for size-calculation overflow.
17546 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17547 do, as we prefer signed integers.
17548 (id_to_widget.max_size, id_to_widget.used)
17549 (xg_store_widget_in_map, xg_remove_widget_from_map)
17550 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
17551 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
17552 Use and return ptrdiff_t, not int.
17553 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
17554 * gtkutil.h: Change prototypes to match the above.
17556 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
17557 are duplicate now that they've been promoted to lisp.h.
17558 (x_allocate_bitmap_record, x_alloc_image_color)
17559 (make_image_cache, cache_image, xpm_load):
17560 Don't update size until alloc is done.

17571 Use ptrdiff_t, not int, to count maps.
17572 (read_char_minibuf_menu_prompt): Check for overflow in size
17573 calculations. Don't update size until allocation succeeds.
17574 Redo calculations to avoid overflow.
17575 * keyboard.h: Change prototypes to match the above.
17577 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

17603 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17604 for command line length. Do not attempt to address one before the
17605 beginning of an array, as that's not portable.
17607 * term.c (max_frame_lines): Remove; unused.
17608 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
17610 (encode_terminal_code, calculate_costs): Check for size

17640 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17641 sizes, since they can exceed INT_MAX in size. Check for size

17645 (xg_select): Check for size calculation overflow.
17646 Don't update size until alloc done.
17648 * xrdb.c (get_environ_db): Don't assume path length fits in int,
17649 as sprintf is limited to int lengths.
17651 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17652 (X_LONG_MIN): New macros.
17653 Use them to make the following changes clearer.
17654 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17655 This change doesn't affect the value now, but it may help remind
17656 future maintainers not to raise the value too much later.
17657 (SELECTION_QUANTUM): Remove, replacing with ...
17658 (selection_quantum): ... new function, which avoids overflow.
17660 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17661 assumption that selection length fits in 'int'.

17674 (lisp_data_to_selection_data, x_property_data_to_lisp):

17678 Don't store size until memory allocation succeeds.
17679 (x_get_window_property): Plug memory leak on memory exhaustion.
17680 Don't double-block input; malloc is safe here. Don't assume 2**34
17681 - 4 fits in unsigned long. Add an xassert to check
17682 XGetWindowProperty overflow. Be more careful about overflow
17683 calculations, and distinguish size from memory overflow better.

17685 unsigned int is less than INT_MAX.
17686 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
17687 harmful) conversions of unsigned short to int.
17688 (lisp_data_to_selection_data): Don't assume that integers
17689 in the range -65535 through -1 fit in an X unsigned short.
17690 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17691 result parameters unless successful. Rely on cons_to_unsigned
17692 to report problems with elements; the old code wasn't right anyway.
17693 (x_check_property_data): Check for int overflow; we cannot use
17694 a wider type due to X limits.
17695 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

17727 * lisp.h (hash_lookup, hash_put):
17728 * minibuf.c (Ftest_completion):
17729 Use ptrdiff_t for hash table indexes, not int (which is too
17730 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17731 32-bit --with-wide-int hosts).
17733 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17734 Add a FIXME comment about memory leaks.
17735 (syms_of_charset): Don't assume xmalloc returns.

17742 with outlandish widths.
17743 * character.h (sanitize_tab_width): Rename from sanitize_width,
17744 now that we have two such functions. All uses changed.

17765 exceed limits imposed by XClientMessageEvent, as well as the usual
17766 ptrdiff_t and size_t limits.
17768 * keyboard.c: Overflow, signedness and related fixes.

17772 Change bufsize argument back to int, undoing my 2011-03-30 change.
17773 We prefer signed types, and int is wide enough here.
17774 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17775 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17776 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17777 length, not size_t. Use ptrdiff_t for index, not int.
17778 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17779 possibility of integer overflow.
17781 Overflow, signedness and related fixes for images.
17783 * dispextern.h (struct it.stack[0].u.image.image_id)
17784 (struct_it.image_id, struct image.id, struct image_cache.size)
17785 (struct image_cache.used, struct image_cache.ref_count):
17786 * gtkutil.c (update_frame_tool_bar):
17787 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
17788 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
17789 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
17790 * nsmenu.m (update_frame_tool_bar):
17791 * xdisp.c (calc_pixel_width_or_height):
17792 * xfns.c (image_cache_refcount):
17793 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
17794 on typical 64-bit hosts.
17796 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
17797 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

17800 when the callers expect that.
17801 (image_ascent): Redo ascent calculation to avoid int overflow.
17802 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17803 (lookup_image): Remove unnecessary tests.
17804 (xbm_image_p): Locals are now of int, not EMACS_INT,
17805 since parse_image_check makes sure they fit into int.
17806 (png_load, gif_load, svg_load_image):
17807 Prefer int to unsigned where either will do.
17808 (tiff_handler): New function, combining the cores of the
17809 old tiff_error_handler and tiff_warning_handler.
17810 This function is rewritten to use vsnprintf and thereby avoid
17811 stack buffer overflows. It uses only the features of vsnprintf
17812 that are common to both POSIX and native Microsoft.
17813 (tiff_error_handler, tiff_warning_handler): Use it.
17814 (tiff_load, gif_load, imagemagick_load_image):
17815 Don't assume :index value fits in 'int'.
17816 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17817 (imagemagick_load_image): Check that crop parameters fit into
17818 the integer types that MagickCropImage accepts. Don't assume
17819 Vimagemagick_render_type has a nonnegative value. Don't assume
17820 size_t fits in 'long'.
17821 (gs_load): Use printmax_t to print the widest integers possible.
17822 Check for integer overflow when computing image height and width.
17824 2011-08-26 Eli Zaretskii <eliz@gnu.org>
17826 * xdisp.c (redisplay_window): Don't force window start if point

17834 handle_single_display_spec, not just 1 or zero.
17835 (handle_single_display_spec): If the display spec is of the form
17836 `(space ...)', and specifies display in the text area, return 2
17838 (try_cursor_movement): Check for the need to scroll more
17839 accurately, and prefer exact match for point under bidi.
17840 Don't advance `row' beyond the last row of the window.
17842 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17843 into disp_prop; all users changed.
17845 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
17846 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
17847 for the text covered by the display property.

17857 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
17858 buffers, return left-to-right.
17859 (set_cursor_from_row): Consider candidate row a win if its glyph
17860 represents a newline and point is on that newline. Fixes cursor
17861 positioning on the newline at EOL of R2L text within L2R
17862 paragraph, and vice versa.
17863 (try_cursor_movement): Check continued rows, in addition to
17864 continuation rows. Fixes unwarranted scroll when point enters a
17865 continued line of R2L text within an L2R paragraph, or vice versa.
17866 (cursor_row_p): Consider the case of point being equal to
17867 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17868 from the end of a short line to the beginning of a continued line
17869 of R2L text within L2R paragraph.
17870 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
17871 composed characters.
17873 * bidi.c (bidi_check_type): Use xassert.
17874 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
17877 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17879 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of

17884 * nsfont.m (ns_otf_to_script): Fix typo.
17886 2011-08-22 Kenichi Handa <handa@m17n.org>
17888 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17889 extra slot even if the purpose is char-code-property-table.
17891 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17893 * xdisp.c (redisplay_window): When computing centering_position,
17894 account for the height of the header line. (Bug#8874)
17896 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17897 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17898 candidate is selected by the mouse, and that candidate has a
17899 composed character under the mouse.
17901 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17902 coordinates reported by pos-visible-in-window-p for a composed
17903 character in column zero.
17905 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17907 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17909 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17911 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17912 consider it a hit if to_charpos is anywhere in the range of the
17913 composed buffer positions.
17915 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17917 * image.c (gif_load): Don't assume that each subimage has the same
17918 dimensions as the base image. Handle disposal method that is
17919 "undefined" by the gif spec (Bug#9335).
17921 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17923 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
17924 (Fcondition_case): Document `debug' symbol in error handler.
17926 2011-08-19 Eli Zaretskii <eliz@gnu.org>
17928 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17929 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17930 from an Org mode buffer to a Speedbar frame.
17932 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17933 a composition, take its buffer position from IT->cmp_it.charpos.
17934 Fixes cursor positioning at the beginning of a line that begins
17935 with a composed character.
17937 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17939 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17940 character bidirectional type, use STRONG_L instead. Fixes crashes
17941 in a buffer produced by `describe-categories'.
17943 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17944 members before the level stack, so they would be saved and
17945 restored when copying iterator state. Fixes incorrect reordering
17946 around TABs covered by display properties.
17948 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17950 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

18016 after the pid of the process is set to -1 (Bug#8162).
18018 2011-08-14 Eli Zaretskii <eliz@gnu.org>
18020 * xdisp.c (move_it_in_display_line_to): Don't invoke
18021 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
18022 ppos_it. Fixes vertical cursor motion when line beginning is
18023 covered by an image. (Bug#9296)
18025 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
18027 * nsterm.h (ns_run_ascript): Declare.

18031 (ns_run_ascript): New function.
18032 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
18033 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
18034 the event loop. Get status from as_status (Bug#7276).
18036 * nsterm.m (sendEvent): If event is NSApplicationDefined and
18037 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
18038 the event loop (Bug#7276).
18040 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

18064 (Fnetwork_interface_list): Allocate in increments of bytes instead
18065 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
18066 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
18068 (struct ifflag_def): notrailers is smart on OSX.
18069 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
18070 Get hardware address with getifaddrs if available.
18072 2011-08-12 Eli Zaretskii <eliz@gnu.org>
18074 * xdisp.c (iterate_out_of_display_property): xassert that
18075 IT->position is set to within IT->object's boundaries. Break from
18076 the loop as soon as EOB is reached; avoids infloops in redisplay
18077 when IT->position is set up wrongly due to some bug.
18078 Set IT->current to match the bidi iterator unconditionally.
18079 (push_display_prop): Allow GET_FROM_STRING as IT->method on
18080 entry. Force push_it to save on the stack the current
18081 buffer/string position, to be restored by pop_it. Fix flags in
18082 the iterator structure wrt the object coming from a display
18083 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
18084 properties. (Bug#9284)
18086 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
18088 * fontset.c (fontset_get_font_group): Add proper type checks.

18101 no-display-properties-and-no-overlays under bidi display.
18102 Set disp_pos in the bidi iterator to avoid searches for display
18103 properties and overlays.
18105 2011-08-08 Chong Yidong <cyd@stupidchicken.com>

18116 restore_point_unwind (Bug#5984).
18118 2011-08-07 Juri Linkov <juri@jurta.org>
18120 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
18121 to show the arg `TIME' instead of `TIMEVAL'.

18125 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
18126 display property strides EOL and includes a newline, as in
18127 longlines-mode. (Bug#9254)
18128 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
18129 word-wrap under bidirectional display. (Bug#9224)
18131 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
18132 is non-zero, even if the data buffer is NULL. Fixes a crash in
18133 vertical-motion with longlines-mode. (Bug#9254)
18135 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18137 * bidi.c <bidi_cache_total_alloc>: Now static.

18143 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
18144 amount allocated this far in `bidi_cache_total_alloc'.
18145 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
18146 non-zero, only free the data buffer without restoring the cache
18147 contents. All callers changed.
18149 * dispextern.h (bidi_unshelve_cache): Update prototype.
18151 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

18212 DISP_PROP_P, and pass it to compute_display_string_pos.
18213 Only handle text covered by a display string if DISP_PROP_P is returned
18214 non-zero. All callers of bidi_fetch_char changed.

18233 * xdisp.c (forward_to_next_line_start): Accept additional argument
18234 BIDI_IT_PREV, and store into it the state of the bidi iterator had
18236 (reseat_at_next_visible_line_start): Use the bidi iterator state
18237 returned by forward_to_next_line_start to restore the state of
18238 it->bidi_it after backing up to previous newline. (Bug#9212)
18240 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
18242 * regex.c (re_comp): Protoize.
18243 (re_exec): Fix return type.
18244 (regexec): Fix type of `ret'. (Bug#9203)
18246 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18248 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
18249 This is needed if max-image-size is a floating-point number.
18251 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18253 * print.c (print_object): Print empty symbol as ##.
18255 * lread.c (read1): Read ## as empty symbol.
18257 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18259 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
18260 setting frame foreground color (Bug#9175).
18261 (x_set_background_color): Likewise.
18263 * nsmenu.m (-setText): Size tooltip dimensions precisely to
18264 contents (Bug#9176).
18265 (EmacsTooltip -init): Remove bezels and add shadows to
18268 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
18269 or scroll bar (Bug#8470).
18271 * nsfont.m (nsfont_open): Remove assignment to voffset and
18272 unnecessary vars hshink, expand, hd, full_height, min_height.
18273 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
18275 * nsterm.h (nsfont_info): Remove voffset field.
18277 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18279 Implement strike-through and overline on NextStep (Bug#8863).
18281 * nsfont.m (nsfont_open): Use underline position provided by font,
18282 instead of hard-coded value of 2.
18283 (nsfont_draw): Call ns_draw_text_decoration instead.
18285 * nsterm.h: Add declaration for ns_draw_text_decoration.
18287 * nsterm.m (ns_draw_text_decoration): New function for drawing
18288 underline, overline, and strike-through.
18289 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
18290 ns_draw_text_decoration. Change treatment of cursor drawing to
18291 accommodate underlining, etc.
18293 2011-07-28 Eli Zaretskii <eliz@gnu.org>
18295 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
18298 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18300 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18301 Without this fix, if a signal arrives just after memory fills up,
18302 'malloc' might be invoked reentrantly.
18304 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18305 In other words, assume that every image size is allowed, on non-X
18306 hosts. This assumption is probably wrong, but it lets Emacs compile.
18308 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18310 * regex.c (re_iswctype): Convert return values to boolean.
18312 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
18314 * xdisp.c (compute_display_string_pos): Don't use cached display
18315 string position if the buffer had its restriction changed.
18318 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18320 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18322 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18324 Integer signedness and overflow and related fixes. (Bug#9079)
18326 * bidi.c: Integer size and overflow fixes.
18327 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18328 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18329 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18330 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18331 (bidi_find_other_level_edge):
18332 Use ptrdiff_t instead of EMACS_INT where either will do.
18333 This works better on 32-bit hosts configured --with-wide-int.
18334 (bidi_cache_ensure_space): Check for size-calculation overflow.
18335 Use % rather than repeated addition, for better worst-case speed.
18336 Don't set bidi_cache_size until after xrealloc returns, because it
18338 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18339 (bidi_cache_ensure_space): Also check that the bidi cache size
18340 does not exceed that of the largest Lisp string or buffer. See Eli
18341 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18343 * alloc.c (__malloc_size_t): Remove.
18344 All uses replaced by size_t. See Andreas Schwab's note
18345 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18347 * image.c: Improve checking for integer overflow.
18348 (check_image_size): Assume that f is nonnull, since
18349 it is always nonnull in practice. This is one less thing to
18350 worry about when checking for integer overflow later.
18351 (x_check_image_size): New function, which checks for integer
18352 overflow issues inside X.
18353 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18354 This removes the need for a memory_full check.
18355 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18356 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18357 (xbm_read_bitmap_data): Change locals back to 'int', since
18358 their values must fit in 'int'.
18359 (xpm_load_image, png_load, tiff_load):
18360 Invoke x_create_x_image_and_pixmap earlier,
18361 to avoid much needless work if the image is too large.
18362 (tiff_load): Treat overly large images as if
18363 x_create_x_image_and_pixmap failed, not as malloc failures.
18364 (gs_load): Use x_check_image_size.
18366 * gtkutil.c: Omit integer casts.
18367 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18368 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18370 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18372 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18373 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18374 would wrongly return t on a 64-bit host.
18376 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18377 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18378 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18379 and therefore cause GCC to emit a bogus diagnostic in some cases.
18381 * image.c: Integer signedness and overflow and related fixes.
18382 This is not an exhaustive set of fixes, but it's time to
18383 record what I've got.
18384 (lookup_pixel_color, check_image_size): Remove redundant decls.
18385 (check_image_size): Don't assume that arbitrary EMACS_INT values
18386 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18387 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18388 (tiff_load, imagemagick_load_image):
18389 Check for overflow in size calculations.
18390 (x_create_x_image_and_pixmap): Remove unnecessary test for
18391 xmalloc returning NULL; that can't happen.
18392 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18393 (xpm_color_bucket): Use better integer hashing function.
18394 (xpm_cache_color): Don't possibly over-allocate memory.
18395 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18396 (gif_memory_source):
18397 Use ptrdiff_t, not int or size_t, to record sizes.
18398 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18399 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18400 either works, as we prefer signed integers.
18401 (tiff_read_from_memory, tiff_write_from_memory):
18402 Return tsize_t, not size_t, since that's what the TIFF API wants.
18403 (tiff_read_from_memory): Don't fail simply because the read would
18404 go past EOF; instead, return a short read.
18405 (tiff_load): Omit no-longer-needed casts.
18406 (Fimagemagick_types): Don't assume size fits into 'int'.
18408 Improve hashing quality when configured --with-wide-int.
18409 * fns.c (hash_string): New function, taken from sxhash_string.
18410 Do not discard information about ASCII character case; this
18411 discarding is no longer needed.
18412 (sxhash-string): Use it. Change sig to match it. Caller changed.
18413 * lisp.h: Declare it.
18414 * lread.c (hash_string): Remove, since we now use fns.c's version.
18415 The fns.c version returns a wider integer if --with-wide-int is
18416 specified, so this should help the quality of the hashing a bit.
18418 * emacs.c: Integer overflow minor fix.
18419 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18420 Define only if GNU_LINUX.
18421 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18423 * dispnew.c: Integer signedness and overflow fixes.
18424 Remove unnecessary forward decls, that were a maintenance hassle.
18425 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18427 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18428 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18429 (prepare_desired_row, line_draw_cost):
18430 Use int, not unsigned, where either works.
18431 (save_current_matrix, restore_current_matrix):
18432 Use ptrdiff_t, not size_t, where either works.
18433 (init_display): Check for overflow more accurately, and without
18434 relying on undefined behavior.
18436 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18437 Remove, replacing with the new symbols in lisp.h. All uses changed.
18438 * fileio.c (make_temp_name):
18439 * filelock.c (lock_file_1, lock_file):
18440 * xdisp.c (message_dolog):
18441 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18442 Use pMd etc. instead.
18443 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18444 replacing the pWIDE etc. symbols removed from editfns.c.
18446 * keyboard.h (num_input_events): Now uintmax_t.
18447 This is (very slightly) less likely to mess up due to wraparound.
18450 * buffer.c: Integer signedness fixes.
18451 (alloc_buffer_text, enlarge_buffer_text):
18452 Use ptrdiff_t rather than size_t when either will do, as we prefer
18455 * alloc.c: Integer signedness and overflow fixes.
18456 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18457 (__malloc_size_t): Default to size_t, not to int.
18458 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18459 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18460 Prefer ptrdiff_t to size_t when either would do, as we prefer
18462 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18463 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18464 Now const. Initialize with values that are in range even if char
18466 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18467 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18468 These functions do the right thing with sizes > 2**32.
18469 (check_depth): Now ptrdiff_t, not int.
18470 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18471 Adjust to new way of storing sizes. Check for size overflow bugs
18473 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18474 slightly wrong anyway, as it missed one instance of
18475 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18476 (refill_memory_reserve): Omit needless cast to size_t.
18477 (mark_object_loop_halt): Mark as externally visible.
18479 * xselect.c: Integer signedness and overflow fixes.
18480 (Fx_register_dnd_atom, x_handle_dnd_message):
18481 Use ptrdiff_t, not size_t, since we prefer signed.
18482 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18483 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18484 x_dnd_atoms_size and x_dnd_atoms_length.
18486 * doprnt.c: Prefer signed to unsigned when either works.
18488 * doprnt.c (doprnt):
18490 * xdisp.c (vmessage):
18491 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18492 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18493 prefer signed arithmetic to avoid comparison confusion.
18494 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18495 but is a bit tricky.
18497 Assume freestanding C89 headers, string.h, stdlib.h.
18498 * data.c, doprnt.c, floatfns.c, print.c:
18499 Include float.h unconditionally.
18500 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18501 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18502 * regex.c: Likewise for stddef.h, string.h.
18503 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18504 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18505 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18506 (STDC_HEADERS): Remove obsolete defines.
18507 * sysdep.c: Include limits.h unconditionally.
18509 Assume support for memcmp, memcpy, memmove, memset.
18510 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18511 * regex.c (memcmp, memcpy):
18512 Remove; we assume C89 now.
18514 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18515 (__malloc_safe_bcopy): Remove; no longer needed.
18517 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18518 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18519 well either way, and we prefer signed to unsigned.
18521 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18523 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18524 closes the connection while we're reading (bug#9182).
18526 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18528 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18529 are specified (Bug#9168).
18531 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18533 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18534 Found by GCC static checking and --with-wide-int on a 32-bit host.
18536 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18538 * xdisp.c (compute_display_string_pos): Fix logic of caching
18539 previous display string position. Initialize cached_prev_pos to
18540 -1. Fixes slow-down at the beginning of a buffer.
18542 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18544 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18545 for attrs[LFACE_FONTSET_INDEX].
18547 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18549 * xml.c (parse_region): Remove unused local
18550 that was recently introduced.
18552 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18554 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18555 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18557 * xdisp.c (move_it_in_display_line_to): Record the best matching
18558 position for TO_CHARPOS while scanning the line, and restore it on
18559 exit if none of the characters scanned was an exact match.
18560 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18561 when exact match is impossible due to invisible text, and the
18562 lines are truncated.
18564 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18566 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18569 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18571 Fix a significant slow-down of cursor motion with C-n, C-p,
18572 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18573 auto-repeat under bidi redisplay in fontified buffers.
18574 * xdisp.c (compute_stop_pos_backwards): New function.
18575 (next_element_from_buffer): Call compute_stop_pos_backwards to
18576 find a suitable prev_stop when we find ourselves before
18578 (reseat): Don't look for prev_stop, as that could mean a very long
18580 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18581 <cached_disp_overlay_modiff>: Cache for last found display string
18583 (compute_display_string_pos): Return the cached position if asked
18584 about the same buffer in the same area of character positions, and
18585 the buffer wasn't changed since the time the display string
18586 position was cached.
18588 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18590 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18591 is an integer, which is important for empty lines. (Bug#9149)
18593 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18595 * frame.c (Fmodify_frame_parameters): In tty case, update the
18596 default face if necessary (Bug#4238).
18598 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18600 * editfns.c (Fstring_to_char): No need to explain what a character
18601 is in the docstring (Bug#6576).
18603 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18605 * xml.c (parse_region): Make sure we always return a tree.
18607 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18609 * xml.c (parse_region): If a document contains only comments,
18612 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18614 * xml.c (make_dom): Return comments, too.
18616 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18619 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18620 and the surrounding thread.
18621 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18622 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18623 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18625 * s/openbsd.h (BROKEN_SIGIO): Define.
18626 * unexelf.c (unexec) [__OpenBSD__]:
18627 Don't update the .mdebug section of the Alpha COFF symbol table.
18629 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18631 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18634 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18636 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18637 This fixes some race conditions on the permissions of any newly
18640 * alloc.c (valid_pointer_p): Use pipe, not open.
18641 This fixes some permissions issues when debugging.
18643 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18644 If fchown fails to set both uid and gid, try to set just gid,
18645 as that is sometimes allowed. Adjust the file's mode to eliminate
18646 setuid or setgid bits that are inappropriate if fchown fails.
18648 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18650 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18651 to compare Lisp_Objects.
18652 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18653 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18654 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18656 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18658 * lread.c (read_integer): Unread even EOF character.
18659 (read1): Likewise. Properly record start position of symbol.
18661 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18662 symbol character follows.
18664 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18666 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18667 This works around a problem with the previous change to Fcopy_file.
18668 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18669 and without this change, GCC might complain about discarding
18670 fchown's return value.
18672 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18674 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

18768 the iterator is before prev_stop.
18769 (init_iterator): Initialize bidi_p from the default value of

19287 Random fixes. E.g., (random) never returned negative values.
19288 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19289 subseconds part to the entropy, as that's a bit more random.
19290 Prefer signed to unsigned, since the signedness doesn't matter and
19291 in general we prefer signed. When given a limit, use a
19292 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19293 latter isn't right if USE_2_TAGS_FOR_INTS.
19294 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19295 not 0..VALMASK. Don't discard "excess" bits that random () returns.

19319 error be more correct.
19321 * fns.c (Frequire): Remove the mention of the .gz files, since

19338 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19339 Also (re)move comments that are misplaced or no longer relevant.

19441 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19442 signed bit field, as this assumption is not portable and it makes
19443 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19444 "char debug_on_exit : 1" as this is not portable either; instead,
19445 use the portable "unsigned int debug_on_exit : 1". Remove unused
19446 member evalargs. Remove obsolete comments about cc bombing out.

19610 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
19612 Integer and buffer overflow fixes (Bug#8873).
19614 * print.c (printchar, strout): Check for string overflow.
19615 (PRINTPREPARE, printchar, strout):
19616 Don't set size unless allocation succeeds.
19618 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19619 for sizes. Check for string overflow more accurately.
19620 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
19622 * macros.c: Integer and buffer overflow fixes.
19623 * keyboard.h (struct keyboard.kbd_macro_bufsize):
19624 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
19625 Use ptrdiff_t, not int, for sizes.
19626 Don't increment bufsize until after realloc succeeds.
19627 Check for size-calculation overflow.
19628 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
19630 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
19632 * lread.c: Integer overflow fixes.
19633 (read_integer): Radix is now EMACS_INT, not int,
19634 to improve quality of diagnostics for out-of-range radices.
19635 Calculate buffer size correctly for out-of-range radices.
19636 (read1): Check for integer overflow in radices, and in
19637 read-circle numbers.
19638 (read_escape): Avoid int overflow.
19639 (Fload, openp, read_buffer_size, read1)
19640 (substitute_object_recurse, read_vector, read_list, map_obarray):
19641 Use ptrdiff_t, not int, for sizes.

19656 2011-06-22 Leo Liu <sdl.web@gmail.com>
19658 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
19659 Move to minibuffer.el.
19661 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19663 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19664 The following patches are for when GLYPH_DEBUG && !XASSERT.
19665 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19666 * dispnew.c (flush_stdout):
19667 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19668 Mark as externally visible.
19669 * dispnew.c (check_window_matrix_pointers): Now static.
19670 * dispnew.c (window_to_frame_vpos):
19671 * xfns.c (unwind_create_frame):
19672 * xterm.c (x_check_font): Remove unused local.
19673 * scroll.c (CHECK_BOUNDS):
19674 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19675 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19676 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19677 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19678 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19680 (debug_method_add): Use va_list and vsprintf rather than relying
19681 on undefined behavior with wrong number of arguments.
19682 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19683 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19684 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19685 since we're not interested in debugging glyphs with old libraries.
19686 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19687 GCC 4.6.0's static checking.
19689 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19691 Integer overflow and signedness fixes (Bug#8873).

19700 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
19701 (x_create_bitmap_from_xpm_data):
19702 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19703 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19705 * xfaces.c (load_pixmap):
19706 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
19707 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19708 (.bitmaps_last, struct x_output.icon_bitmap):
19709 Use ptrdiff_t, not int, for bitmap indexes.
19710 (x_allocate_bitmap_record): Check for size overflow.
19711 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19713 Use ptrdiff_t, not int, for overlay counts.
19714 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19715 * editfns.c (overlays_around, get_pos_property):
19716 * textprop.c (get_char_property_and_overlay):
19717 * xdisp.c (next_overlay_change, note_mouse_highlight):
19718 * xfaces.c (face_at_buffer_position):
19719 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19720 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19721 (Fnext_overlay_change, Fprevious_overlay_change)
19722 (mouse_face_overlay_overlaps, Foverlays_in):
19723 Use ptrdiff_t, not int, for sizes.
19724 (overlays_at, overlays_in): Check for size-calculation overflow.
19726 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19728 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19729 (x_session_initialize): Do not assume string length fits in int.
19731 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19732 This is unlikely, but can occur if DPI is outlandish.
19734 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19735 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19737 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19738 * xrdb.c (magic_file_p, search_magic_path):
19739 Omit last arg SUFFIX; it was always 0. All callers changed.
19740 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19742 * xfont.c (xfont_match): Avoid need for strlen.
19744 * xfns.c: Don't assume strlen fits in int.
19745 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19747 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19748 not unsigned long, as we prefer signed integers. All callers changed.
19749 Detect integer overflow in repeat count.
19750 (message_dolog): Don't assume print length fits in 39 bytes.
19751 (display_mode_element): Don't assume strlen fits in int.
19753 * termcap.c: Don't assume sizes fit in int and never overflow.
19754 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19755 (gobble_line): Check for size-calculation overflow.
19757 * minibuf.c (Fread_buffer):
19758 * lread.c (intern, intern_c_string):
19759 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19760 Don't assume string length fits in int.
19762 * keyboard.c (parse_tool_bar_item):
19763 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19765 * font.c: Don't assume string length fits in int.
19766 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19767 Use ptrdiff_t, not int.
19768 (font_intern_prop): Don't assume string length fits in int.
19769 Don't assume integer property fits in fixnum.
19770 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19772 * filelock.c: Fix some buffer overrun and integer overflow issues.
19773 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19774 Reformulate so as not to need the command string.
19775 Invoke gzip -cd rather than gunzip, as it's more portable.
19776 (lock_info_type, lock_file_1, lock_file):
19777 Don't assume pid_t and time_t fit in unsigned long.
19778 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19779 (current_lock_owner): Prefer signed type for sizes.
19780 Use memcpy, not strncpy, where memcpy is what is really wanted.
19781 Don't assume (via atoi) that time_t and pid_t fit in int.
19782 Check for time_t and/or pid_t out of range, e.g., via a network share.
19783 Don't alloca where an auto var works fine.
19785 * fileio.c: Fix some integer overflow issues.
19786 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19787 Don't assume string length fits in int.
19788 (directory_file_name): Don't assume string length fits in long.
19789 (make_temp_name): Don't assume pid fits in int, or that its print
19790 length is less than 20.
19792 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19794 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19796 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19798 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19799 We prefer signed integers, even for size calculations.
19801 * emacs.c: Don't assume string length fits in 'int'.
19802 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19803 (main): Don't invoke strlen when not needed.
19805 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19806 (XD_DEBUG_MESSAGE): Don't waste a byte.
19808 * callproc.c (getenv_internal_1, getenv_internal)
19809 (Fgetenv_internal):
19810 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19812 * lread.c (invalid_syntax): Omit length argument.
19813 All uses changed. This doesn't fix a bug, but it simplifies the
19814 code away from its former Hollerith-constant appearance, and it's
19815 one less 'int' to worry about when looking at integer-overflow issues.
19816 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19818 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19819 This didn't break anything, but it didn't help either.
19820 It's confusing to put a bogus integer in a place where the actual
19821 value does not matter.
19822 (LIST_END_P): Remove unused macro and its bogus comment.
19823 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19825 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19826 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19828 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19829 We prefer signed types, and the value cannot exceed the EMACS_INT
19830 range anyway (because otherwise the length would not be representable).
19831 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19832 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19833 This avoids a GCC warning when WIDE_EMACS_INT.
19835 * indent.c (sane_tab_width): New function.
19836 (current_column, scan_for_column, Findent_to, position_indentation)
19837 (compute_motion): Use it. This is just for clarity.
19838 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19840 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19842 * lisp.h (lint_assume): New macro.
19843 * composite.c (composition_gstring_put_cache):
19844 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19846 * editfns.c, insdel.c:
19847 Omit unnecessary forward decls, to simplify future changes.
19849 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19851 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19853 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19854 Use much-faster test for byte-length change.
19855 Don't assume string byte-length fits in 'int'.
19856 Check that character arg fits in 'int'.
19857 (mapcar1): Declare byte as byte, for clarity.
19859 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19861 * fns.c (concat): Catch string overflow earlier.
19862 Do not rely on integer wraparound.
19864 * dispextern.h (struct it.overlay_strings_charpos)
19865 (struct it.selective): Now EMACS_INT, not int.
19866 * xdisp.c (forward_to_next_line_start)
19867 (back_to_previous_visible_line_start)
19868 (reseat_at_next_visible_line_start, next_element_from_buffer):
19869 Don't arbitrarily truncate the value of 'selective' to int.
19871 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19873 * composite.c: Don't truncate sizes to 'int'.
19874 (composition_gstring_p, composition_reseat_it)
19875 (composition_adjust_point): Use EMACS_INT, not int.
19876 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19877 not EMACS_UINT, for indexes.
19879 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19881 * buffer.c: Include <verify.h>.
19882 (struct sortvec.priority, struct sortstr.priority):
19883 Now EMACS_INT, not int.
19884 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19885 (struct sortstr.size, record_overlay_string)
19886 (struct sortstrlist.size, struct sortlist.used):
19887 Don't truncate size to int.
19888 (record_overlay_string): Check for size-calculation overflow.
19889 (init_buffer_once): Check at compile-time, not run-time.
19891 2011-06-22 Jim Meyering <meyering@redhat.com>
19893 Don't leak an XBM-image-sized buffer
19894 * image.c (xbm_load): Free the image buffer after using it.
19896 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19899 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19900 that Sun C diagnosed.
19901 * fns.c (secure_hash): Fix pointer signedness issue.
19902 * intervals.c (static_offset_intervals): New function.
19903 (offset_intervals): Use it.
19905 2011-06-21 Leo Liu <sdl.web@gmail.com>
19908 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19911 * fns.c (secure_hash): Rename from crypto_hash_function and change
19912 the first arg to accept symbols.
19913 (Fsecure_hash): New primitive.
19914 (syms_of_fns): New symbols.
19916 2011-06-20 Deniz Dogan <deniz@dogan.se>
19918 * process.c (Fset_process_buffer): Clarify return value in
19921 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19923 * dispnew.c (add_window_display_history): Use BVAR.
19925 * xdisp.c (debug_method_add): Use BVAR.
19926 (check_window_end, dump_glyph_matrix, dump_glyph)
19927 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19929 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19932 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19933 check till after the cache is created in init_frame_faces.
19935 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19937 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19939 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19941 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19942 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19943 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19945 Improve buffer-overflow checking (Bug#8873).
19946 * fileio.c (Finsert_file_contents):
19947 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19948 Remove the old (too-loose) buffer overflow checks.
19949 They weren't needed, since make_gap checks for buffer overflow.
19950 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19951 The old code merely checked for Emacs fixnum overflow, and relied
19952 on undefined (wraparound) behavior. The new code avoids undefined
19953 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19955 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19956 Tune. Don't use wider integers than needed. Don't use alloca.
19957 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19959 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19961 * insdel.c, lisp.h (buffer_overflow): New function.
19962 (insert_from_buffer_1, replace_range, replace_range_2):
19963 * insdel.c (make_gap_larger):
19964 * editfns.c (Finsert_char):
19965 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19967 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19969 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19971 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19973 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19974 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19976 * fileio.c: Don't assume EMACS_INT fits in off_t.
19977 (emacs_lseek): New static function.
19978 (Finsert_file_contents, Fwrite_region): Use it.
19979 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19981 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19983 * fns.c: Don't overflow int when computing a list length.
19984 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19985 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19986 truncation on 64-bit hosts. Check for QUIT every
19987 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19988 faster and is responsive enough.
19989 (Flength): Report an error instead of overflowing an integer.
19990 (Fsafe_length): Return a float if the value is not representable
19991 as a fixnum. This shouldn't happen except in contrived situations.
19992 (Fnthcdr, Fsort): Don't assume list length fits in int.
19993 (Fcopy_sequence): Don't assume vector length fits in int.
19995 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19996 (header_size, word_size): New constants.
19997 (allocate_vectorlike): Don't check size overflow here.
19998 (allocate_vector): Check it here instead, since this is the only
19999 caller of allocate_vectorlike that could cause overflow.
20000 Check that the new vector's length is representable as a fixnum.
20002 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
20003 The previous code was bogus. For example, next_almost_prime (32)
20004 returned 39, which is undesirable as it is a multiple of 3; and
20005 next_almost_prime (24) returned 25, which is a multiple of 5 so
20006 why was the code bothering to check for multiples of 7?
20008 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
20010 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
20012 Variadic C functions now count arguments with ptrdiff_t.
20013 This partly undoes my 2011-03-30 change, which replaced int with size_t.
20014 Back then I didn't know that the Emacs coding style prefers signed int.
20015 Also, in the meantime I found a few more instances where arguments
20016 were being counted with int, which may truncate counts on 64-bit
20017 machines, or EMACS_INT, which may be unnecessarily wide.
20018 * lisp.h (struct Lisp_Subr.function.aMANY)
20019 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
20020 Arg counts are now ptrdiff_t, not size_t.
20021 All variadic functions and their callers changed accordingly.
20022 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
20023 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
20024 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
20025 * callint.c (Fcall_interactively): Check arg count for overflow,
20026 to avoid potential buffer overrun. Use signed char, not 'int',
20027 for 'varies' array, so that we needn't bother to check its size
20028 calculation for overflow.
20029 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
20030 * eval.c (apply_lambda):
20031 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
20032 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
20033 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
20035 * callint.c (Fcall_interactively): Don't use index var as event count.
20037 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
20038 * mem-limits.h (SIZE): Remove; no longer used.
20040 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
20042 Remove unnecessary casts.
20043 * xterm.c (x_term_init):
20044 * xfns.c (x_set_border_pixel):
20045 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
20046 These aren't needed now that we assume ANSI C.
20048 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
20049 It's more likely to cause problems (due to unsigned overflow)
20052 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
20054 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
20056 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
20058 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
20060 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
20062 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
20064 GLYPH_CODE_FACE returns EMACS_INT, not int.
20065 * dispextern.h (merge_faces):
20066 * xfaces.c (merge_faces):
20067 * xdisp.c (get_next_display_element, next_element_from_display_vector):
20068 Don't assume EMACS_INT fits in int.
20070 * character.h (CHAR_VALID_P): Remove unused parameter.
20071 * fontset.c, lisp.h, xdisp.c: All uses changed.
20073 * editfns.c (Ftranslate_region_internal): Omit redundant test.
20075 * fns.c (concat): Minor tuning based on overflow analysis.
20076 This doesn't fix any bugs. Use int to hold character, instead
20077 of constantly refetching from Emacs object. Use XFASTINT, not
20078 XINT, for value known to be a character. Don't bother comparing
20079 a single byte to 0400, as it's always less.
20081 * floatfns.c (Fexpt):
20082 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
20084 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
20087 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
20089 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
20090 Without this fix, on a 64-bit host (aset S 0 4294967386) would
20091 incorrectly succeed when S was a string, because 4294967386 was
20092 truncated before it was used.
20094 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
20095 Otherwise, an out-of-range integer could cause undefined behavior
20098 * composite.c: Use int, not EMACS_INT, for characters.
20099 (fill_gstring_body, composition_compute_stop_pos): Use int, not
20100 EMACS_INT, for values that are known to be in character range.
20101 This doesn't fix any bugs but is the usual style inside Emacs and
20102 may generate better code on 32-bit machines.
20104 Make sure a 64-bit char is never passed to ENCODE_CHAR.
20105 This is for reasons similar to the recent CHAR_STRING fix.
20106 * charset.c (Fencode_char): Check that character arg is actually
20107 a character. Pass an int to ENCODE_CHAR.
20108 * charset.h (ENCODE_CHAR): Verify that the character argument is no
20109 wider than 'int', as a compile-time check to prevent future regressions
20112 * character.c (char_string): Remove unnecessary casts.
20114 Make sure a 64-bit char is never passed to CHAR_STRING.
20115 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
20116 by silently ignoring the top 32 bits, allowing some values
20117 that were far too large to be valid characters.
20118 * character.h: Include <verify.h>.
20119 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
20120 arguments are no wider than unsigned, as a compile-time check
20121 to prevent future regressions in this area.
20123 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
20124 (Fsubst_char_in_region):
20126 * xdisp.c (decode_mode_spec_coding):
20127 Adjust to CHAR_STRING's new requirement.
20128 * editfns.c (Finsert_char, Fsubst_char_in_region):
20129 * fns.c (concat): Check that character args are actually
20130 characters. Without this test, these functions did the wrong
20131 thing with wildly out-of-range values on 64-bit hosts.
20133 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
20134 These casts should not be needed on 32-bit hosts, either.
20135 * keyboard.c (read_char):
20136 * lread.c (Fload): Remove casts to unsigned.
20138 * lisp.h (UNSIGNED_CMP): New macro.
20139 This fixes comparison bugs on 64-bit hosts.
20140 (ASCII_CHAR_P): Use it.
20141 * casefiddle.c (casify_object):
20142 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
20143 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
20144 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
20145 * dispextern.h (FACE_FROM_ID):
20146 * keyboard.c (read_char): Use UNSIGNED_CMP.
20148 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
20149 not to EMACS_INT, to avoid GCC warning.
20151 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
20153 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
20154 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
20155 isn't needed on 32-bit machines.
20157 * buffer.c (Fgenerate_new_buffer_name):
20158 Use EMACS_INT for count, not int.
20159 (advance_to_char_boundary): Return EMACS_INT, not int.
20161 * data.c (Qcompiled_function): Now static.
20163 * window.c (window_body_lines): Now static.
20165 * image.c (gif_load): Rename local to avoid shadowing.
20167 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
20168 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
20169 * alloc.c (make_save_value): Integer argument is now of type
20170 ptrdiff_t, not int.
20171 (mark_object): Use ptrdiff_t, not int.
20172 * lisp.h (pD): New macro.
20173 * print.c (print_object): Use it.
20175 * alloc.c: Use EMACS_INT, not int, to count objects.
20176 (total_conses, total_markers, total_symbols, total_vector_size)
20177 (total_free_conses, total_free_markers, total_free_symbols)
20178 (total_free_floats, total_floats, total_free_intervals)
20179 (total_intervals, total_strings, total_free_strings):
20180 Now EMACS_INT, not int. All uses changed.
20181 (Fgarbage_collect): Compute overall total using a double, so that
20182 integer overflow is less likely to be a problem. Check for overflow
20183 when converting back to an integer.
20184 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
20185 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
20186 These were 'int' variables that could overflow on 64-bit hosts;
20187 they were never used, so remove them instead of repairing them.
20188 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
20189 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
20190 Previously, this ceilinged at INT_MAX, but that doesn't work on
20192 (allocate_pseudovector): Don't use EMACS_INT when int would do.
20194 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
20195 (allocate_vectorlike): Check for ptrdiff_t overflow.
20196 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
20197 when a (possibly-narrower) signed value would do just as well.
20198 We prefer using signed arithmetic, to avoid comparison confusion.
20200 * alloc.c: Catch some string size overflows that we were missing.
20201 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20202 for convenience in STRING_BYTES_MAX.
20203 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
20204 The definition here is exact; the one in lisp.h was approximate.
20205 (allocate_string_data): Check for string overflow. This catches
20206 some instances we weren't catching before. Also, it catches
20207 size_t overflow on (unusual) hosts where SIZE_MAX <= min
20208 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
20209 and ptrdiff_t and EMACS_INT are both 64 bits.
20211 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20212 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
20213 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
20215 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
20217 * alloc.c (Fmake_string): Check for out-of-range init.
20219 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
20221 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
20223 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
20225 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
20226 xg_get_default_scrollbar_width.
20228 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
20229 (int_gtk_range_get_value): Move to the scroll bar part of the file.
20230 (style_changed_cb): Call update_theme_scrollbar_width and call
20231 x_set_scroll_bar_default_width and xg_frame_set_char_size for
20232 all frames (Bug#8505).
20233 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
20234 Call gtk_window_set_resizable if HAVE_GTK3.
20235 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
20236 and height if HAVE_GTK3 (Bug#8505).
20237 (scroll_bar_width_for_theme): New variable.
20238 (update_theme_scrollbar_width): New function.
20239 (xg_get_default_scrollbar_width): Move code to
20240 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
20241 (xg_initialize): Call update_theme_scrollbar_width.
20243 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
20245 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
20247 2011-06-12 Martin Rudalics <rudalics@gmx.at>
20249 * frame.c (make_frame): Call other_buffer_safely instead of
20252 * window.c (temp_output_buffer_show): Call display_buffer with
20253 second argument Vtemp_buffer_show_specifiers and reset latter
20254 immediately after the call.
20255 (Vtemp_buffer_show_specifiers): New variable.
20256 (auto_window_vscroll_p, next_screen_context_lines)
20257 (Vscroll_preserve_screen_position): Remove leading asterisks from
20260 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
20262 Fix minor problems found by GCC 4.6.0 static checking.
20263 * buffer.c (Qclone_number): Remove for now, as it's unused.
20264 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
20265 (record_buffer): Remove unused local.
20266 * frame.c (other_visible_frames, frame_buffer_list): Now static.
20267 (set_frame_buffer_list): Remove; unused.
20268 * frame.h (other_visible_frames): Remove decl.
20269 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
20270 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
20271 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
20273 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
20274 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
20275 Define only if HAVE_GPM.
20276 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
20277 (update_hints_inhibit): Remove; never set. All uses removed.
20278 * widgetprv.h (emacsFrameClassRec): Remove decl.
20279 * window.c (delete_deletable_window): Now returns void, since it
20280 wasn't returning anything.
20281 (compare_window_configurations): Remove unused locals.
20282 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
20283 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
20284 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
20285 the same widths as pointers. This follows up on the 2011-05-06 patch.
20286 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
20287 * xterm.h: Likewise.
20288 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

20293 (LISP_H): Add lib/intprops.h.
20295 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
20297 * image.c (gif_load): Add animation frame delay to the metadata.
20298 (syms_of_image): Use DEFSYM. New symbol `delay'.
20300 2011-06-11 Martin Rudalics <rudalics@gmx.at>
20302 * window.c (delete_deletable_window): Re-add.
20303 (Fset_window_configuration): Rewrite to handle dead buffers and
20304 consequently deletable windows.
20305 (window_tree, Fwindow_tree): Remove. Supply functionality in
20307 (compare_window_configurations): Simplify code.
20309 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
20311 * image.c (imagemagick_load_image): Fix type mismatch.
20312 (Fimagemagick_types): Likewise.
20314 * window.h (replace_buffer_in_windows): Declare.
20316 2011-06-11 Martin Rudalics <rudalics@gmx.at>
20318 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
20319 Qclone_number. Remove external declaration of Qdelete_window.
20320 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
20322 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
20323 Run Qbuffer_list_update_hook if allowed.
20324 (Fother_buffer): Rewrite doc-string. Major rewrite for new
20325 buffer list implementation.
20326 (other_buffer_safely): New function.
20327 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
20328 calls to replace_buffer_in_windows and
20329 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
20331 (record_buffer): Inhibit quitting and rewrite using quittable
20332 functions. Run Qbuffer_list_update_hook if allowed.
20333 (Frecord_buffer, Funrecord_buffer): New functions.
20334 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
20335 Move switch-to-buffer to window.el.
20336 (bury-buffer): Move to window.el.
20337 (Vbuffer_list_update_hook): New variable.
20339 * lisp.h (other_buffer_safely): Add prototype in buffer.c
20342 * window.h (resize_frame_windows): Move up in code.
20343 (Fwindow_frame): Remove EXFUN.
20344 (replace_buffer_in_all_windows): Remove prototype.
20345 (replace_buffer_in_windows_safely): Add prototype.
20347 * window.c: Declare Qdelete_window static again. Move down
20348 declaration of select_count.
20349 (Fnext_window, Fprevious_window): Rewrite doc-strings.
20350 (Fother_window): Move to window.el.
20351 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
20352 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
20353 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
20355 (replace_buffer_in_windows): Implement by calling
20356 Qreplace_buffer_in_windows.
20357 (replace_buffer_in_all_windows): Remove with some functionality
20358 moved into replace_buffer_in_windows_safely.
20359 (replace_buffer_in_windows_safely): New function.
20360 (select_window_norecord, select_frame_norecord): Move in front
20361 of run_window_configuration_change_hook. Remove now obsolete
20363 (Fset_window_buffer): Rewrite doc-string.
20364 Call Qrecord_window_buffer.
20365 (keys_of_window): Move binding for other-window to window.el.
20367 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
20369 * dispextern.h (struct image): Replace data member, whose int_val
20370 and ptr_val fields were not used by anything, with a single
20373 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
20374 (gif_clear_image, gif_load, imagemagick_load_image)

20804 * xdisp.c (set_cursor_from_row): Set start and stop points
20805 according to the row's direction when priming the loop that looks

20808 (display_prop_intangible_p): Reimplement to call
20809 handle_display_spec instead of single_display_spec_intangible_p.

20814 lists with the argument STRING its top-level element.
20815 (display_prop_string_p): Fix the condition for processing a

20820 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20821 value of a `display' property is a "replacing spec".
20822 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20823 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20824 the display property, but just return a value indicating whether
20825 the display property will replace the characters it covers.
20826 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and

20851 All callers changed. (Bug#8762)
20853 * gnutls.c: Use Emacs's memory allocators.
20854 Without this change, the gnutls library would invoke malloc etc.
20855 directly, which causes problems on non-SYNC_INPUT hosts, and which
20856 runs afoul of improving memory_full behavior. (Bug#8761)
20857 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20858 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20859 xfree instead of the default malloc, realloc, free.
20860 (Fgnutls_boot): No need to check for memory allocation failure,
20861 since xmalloc does that for us.

20881 * lisp.h (struct Lisp_Hash_Table):
20882 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20883 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20884 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20885 * alloc.c (allocate_vectorlike):
20886 Check for overflow in vector size calculations.
20887 * ccl.c (ccl_driver):
20888 Check for overflow when converting EMACS_INT to int.
20889 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20890 need to be updated by these changes.
20891 * fns.c (make_hash_table, maybe_resize_hash_table):
20892 Check for integer overflow with large hash tables.
20893 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20894 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20895 (SXHASH_REDUCE): New macro.
20896 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20897 Use it instead of discarding useful hash info with large hash values.
20898 (sxhash_float): New function.
20899 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20900 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20901 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20902 Rewrite to use FIXNUM_BITS, as this simplifies things.
20903 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20904 Adjust signatures to match updated version of code.
20905 (consing_since_gc): Now EMACS_INT, since a single hash table can
20906 use more than INT_MAX bytes.
20908 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20910 Make it possible to build with GCC-4.6+ -O2 -flto.

20919 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20921 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20922 Update dependencies.
20924 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20926 * data.c (init_data): Remove code for UTS, this system is not
20929 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20931 Don't force ./temacs to start in terminal mode.
20933 * frame.c (make_initial_frame): Initialize faces in all cases, not
20934 only when CANNOT_DUMP is defined.
20935 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20937 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20939 * dispnew.c (add_window_display_history): Use const for the string
20940 pointer. Remove declaration, not needed.
20942 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20944 Use 'inline', not 'INLINE'.
20945 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20946 * alloc.c, fontset.c (INLINE): Remove.
20947 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20948 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20949 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20950 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20951 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20953 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20955 Make it possible to run ./temacs.
20957 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20958 syms_of_callproc does the same thing. Remove test for
20959 "initialized", do it in the caller.
20960 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20962 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20964 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20965 (read_minibuf): Use get_minibuffer.
20966 (syms_of_minibuf): Use DEFSYM.
20967 (Qmetadata): New var.
20968 * data.c (Qbuffer): Don't make it static.
20969 (syms_of_data): Use DEFSYM.
20971 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20973 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20974 (CCL_CODE_MIN): New macro.
20976 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20978 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20980 * eval.c (Qdebug): Now static.
20981 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20982 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20983 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20985 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20987 * image.c: Various fixes to ImageMagick code comments.
20988 (Fimagemagick_types): Doc fix.
20990 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20992 Minor fixes prompted by GCC 4.6.0 warnings.
20994 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20996 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20997 (x_clipboard_manager_save_all): Move extern decl to ...
20998 * xterm.h: ... here, so that it can be checked for consistency.
21000 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
21002 * xselect.c (x_clipboard_manager_save_frame)
21003 (x_clipboard_manager_save_all): New functions.
21004 (Fx_clipboard_manager_save): Lisp function deleted.
21006 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
21007 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
21009 * xterm.h: Update prototype.
21011 2011-05-28 William Xu <william.xwl@gmail.com>
21013 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
21014 exiting (Bug#8239).
21016 2011-05-28 Jim Meyering <meyering@redhat.com>
21018 Avoid a sign-extension bug in crypto_hash_function.
21019 * fns.c (to_uchar): Define.
21020 (crypto_hash_function): Use it to convert some newly-signed
21021 variables to unsigned, to avoid sign-extension bugs. For example,
21022 without this change, (md5 "truc") would evaluate to
21023 45723a2aff78ff4fff7fff1114760e62 rather than the expected
21024 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
21025 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
21027 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21029 Integer overflow fixes.
21031 * dbusbind.c: Serial number integer overflow fixes.
21032 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
21033 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
21034 to hold a serial number that is too large for a fixnum.
21035 (Fdbus_method_return_internal, Fdbus_method_error_internal):
21036 Check for serial numbers out of range. Decode any serial number
21037 that was so large that it became a float. (Bug#8722)
21039 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
21040 (Fdbus_call_method, Fdbus_call_method_asynchronously):
21041 Use XFASTINT rather than XUINT when numbers are nonnegative.
21042 (xd_append_arg, Fdbus_method_return_internal):
21043 (Fdbus_method_error_internal): Likewise. Also, for unsigned
21044 arguments, check that Lisp number is nonnegative, rather than
21045 silently wrapping negative numbers around. (Bug#8722)
21046 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
21049 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
21051 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
21053 ccl: Add integer overflow checks.
21054 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
21055 (IN_INT_RANGE): New macros.
21056 (ccl_driver): Use them to check for integer overflow when
21057 decoding a CCL program. Many of the new checks are whether XINT (x)
21058 fits in int; it doesn't always, on 64-bit hosts. The new version
21059 doesn't catch all possible integer overflows, but it's an
21060 improvement. (Bug#8719)
21062 * alloc.c (make_event_array): Use XINT, not XUINT.
21063 There's no need for unsigned here.
21065 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
21066 This follows up to the 2011-05-06 change that substituted uintptr_t
21067 for EMACS_INT. This case wasn't caught back then.
21069 Rework Fformat to avoid integer overflow issues.
21070 * editfns.c: Include <float.h> unconditionally, as it's everywhere
21071 now (part of C89). Include <verify.h>.
21072 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
21073 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
21074 (Fformat): Avoid the prepass trying to compute sizes; it was only
21075 approximate and thus did not catch overflow reliably. Instead, walk
21076 through the format just once, formatting and computing sizes as we go,
21077 checking for integer overflow at every step, and allocating a larger
21078 buffer as needed. Keep track separately whether the format is
21079 multibyte. Keep only the most-recently calculated precision, rather
21080 than them all. Record whether each argument has been converted to
21081 string. Use EMACS_INT, not int, for byte and char and arg counts.
21082 Support field widths and precisions larger than INT_MAX. Avoid
21083 sprintf's undefined behavior with conversion specifications such as %#d
21084 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
21085 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
21086 formatting out-of-range floating point numbers with int
21087 formats. (Bug#8668)
21089 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
21091 * data.c: Avoid integer truncation in expressions involving floats.
21092 * data.c: Include <intprops.h>.
21093 (arith_driver): When there's an integer overflow in an expression
21094 involving floating point, convert the integers to floating point
21095 so that the resulting value does not suffer from catastrophic
21096 integer truncation. For example, on a 64-bit host (* 4
21097 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
21098 Do not rely on undefined behavior after integer overflow.
21100 merge count_size_as_multibyte, parse_str_to_multibyte
21101 * character.c, character.h (count_size_as_multibyte):
21102 Rename from parse_str_to_multibyte; all uses changed.
21103 Check for integer overflow.
21104 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
21105 since it's now a duplicate of the other. This is more of
21106 a character than a buffer op, so better that it's in character.c.
21107 * fns.c, print.c: Adjust to above changes.
21109 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
21111 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
21113 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21115 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21116 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
21117 (x_clipboard_manager_save): Now static.
21118 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
21120 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21121 (crypto_hash_function): Now static.
21122 Fix pointer signedness problems. Avoid unnecessary initializations.
21124 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
21126 * termhooks.h (Vselection_alist): Make it terminal-local.
21128 * terminal.c (create_terminal): Initialize it.
21130 * xselect.c: Support for clipboard managers.
21131 (Vselection_alist): Move to termhooks.h as terminal-local var.
21132 (LOCAL_SELECTION): New macro.
21133 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
21134 (symbol_to_x_atom): Remove gratuitous arg.
21135 (x_handle_selection_request, lisp_data_to_selection_data)
21136 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
21137 (x_own_selection, x_get_local_selection, x_convert_selection):
21138 New arg, specifying work frame. Use terminal-local Vselection_alist.
21139 (some_frame_on_display): Delete unused function.
21140 (Fx_own_selection_internal, Fx_get_selection_internal)
21141 (Fx_disown_selection_internal, Fx_selection_owner_p)
21142 (Fx_selection_exists_p): New optional frame arg.
21143 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
21144 (x_handle_selection_clear): Don't treat other terminals with the
21145 same keyboard specially. Use the terminal-local Vselection_alist.
21146 (x_clear_frame_selections): Use Frun_hook_with_args.
21148 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
21150 * xterm.h: Add support for those atoms.
21152 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
21154 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
21155 (converted_selections, conversion_fail_tag): New global variables.
21156 (x_selection_request_lisp_error): Free the above.
21157 (x_get_local_selection): Remove unnecessary code.
21158 (x_reply_selection_request): Args changed; handle arbitrary array
21159 of converted selections stored in converted_selections.
21160 Separate the XChangeProperty and SelectionNotify steps.
21161 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21162 (x_convert_selection): New function.
21163 (x_handle_selection_event): Simplify.
21164 (x_get_foreign_selection): Don't ignore incoming requests while
21165 waiting for an answer; this will fail when we implement
21166 SAVE_TARGETS, and seems unnecessary anyway.
21167 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21168 (Vx_sent_selection_functions): Doc fix.
21170 2011-05-26 Leo Liu <sdl.web@gmail.com>
21172 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21174 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21176 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21178 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21179 for fringe update if it has periodic bitmap.
21180 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21181 and fringe_bitmap_periodic_p.
21183 * fringe.c (get_fringe_bitmap_data): New function.
21184 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21185 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21186 row. Mark glyph row for fringe update if periodicity changed.
21188 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21189 for fringe update unless it has periodic bitmap.
21191 2011-05-25 Kenichi Handa <handa@m17n.org>

21210 Remove macros that are defined and never used.
21211 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21213 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21215 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21216 (Fx_get_selection_internal): Minor cleanup.
21217 (Fx_own_selection_internal): Rename arguments for consistency with
21220 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

21244 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21246 * systime.h (Time): Define only if emacs is defined.
21247 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21248 where the include path doesn't have X11/X.h by default. See
21249 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21251 2011-05-20 Kenichi Handa <handa@m17n.org>
21253 * composite.c (find_automatic_composition): Fix previous change.
21255 2011-05-20 Glenn Morris <rgm@gnu.org>
21257 * lisp.mk: New file, split from Makefile.in.
21258 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
21259 (shortlisp): Remove.
21260 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
21262 2011-05-19 Glenn Morris <rgm@gnu.org>

21266 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21267 (lisp): Set the order to that of loadup.el.
21268 (shortlisp): Make it a copy of $lisp.
21269 (SOME_MACHINE_LISP): Remove.
21270 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21271 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21273 2011-05-18 Kenichi Handa <handa@m17n.org>
21275 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21276 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21277 (find_automatic_composition): Mostly rewrite for efficiency.
21279 2011-05-18 Juanma Barranquero <lekktu@gmail.com>

21283 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21285 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21286 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21288 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21290 Fix some integer overflow issues, such as string length overflow.
21292 * insdel.c (count_size_as_multibyte): Check for string overflow.
21294 * character.c (lisp_string_width): Check for string overflow.
21295 Use EMACS_INT, not int, for string indexes and lengths; in
21296 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21297 the resulting string length overflows an EMACS_INT; instead,
21298 report a string overflow if no precision given. When checking for
21299 precision exhaustion, use a check that cannot possibly have
21300 integer overflow. (Bug#8675)
21301 * character.h (lisp_string_width): Adjust to new signature.
21303 * alloc.c (string_overflow): New function.
21304 (Fmake_string): Use it. This doesn't change behavior, but saves
21305 a few bytes and will simplify future changes.
21306 * character.c (string_escape_byte8): Likewise.
21307 * lisp.h (string_overflow): New decl.
21309 Fixups, following up to the user-interface timestamp change.
21310 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21311 for UI timestamps, instead of unsigned long.
21312 * msdos.c (mouse_get_pos): Likewise.
21313 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21314 * w32gui.h (Time): Define by including "systime.h" rather than by
21315 declaring it ourselves. (Bug#8664)
21317 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21318 * image.c (clear_image_cache): Likewise.
21320 * term.c (term_mouse_position): Don't assume time_t wraparound.
21322 Be more systematic about user-interface timestamps.
21323 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21324 and sometimes 'EMACS_UINT', to represent these timestamps.
21325 This change causes it to use 'Time' uniformly, as that's what X uses.
21326 This makes the code easier to follow, and makes it easier to catch
21327 integer overflow bugs such as Bug#8664.
21328 * frame.c (Fmouse_position, Fmouse_pixel_position):
21329 Use Time, not unsigned long, for user-interface timestamps.
21330 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21331 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21332 * keyboard.h (last_event_timestamp): Likewise.
21333 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21334 * menu.h (xmenu_show): Likewise.
21335 * term.c (term_mouse_position): Likewise.
21336 * termhooks.h (struct input_event.timestamp): Likewise.
21337 (struct terminal.mouse_position_hook): Likewise.
21338 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21339 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21340 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21341 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21342 what it was before.
21343 * menu.h, termhooks.h: Include "systime.h", for Time.
21345 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21346 Don't assume that the difference between two unsigned long values
21347 can fit into an integer. At this point, we know button_down_time
21348 <= event->timestamp, so the difference must be nonnegative, so
21349 there's no need to cast the result if double-click-time is
21350 nonnegative, as it should be; check that it's nonnegative, just in
21351 case. This bug is triggered when events are more than 2**31 ms
21352 apart (about 25 days). (Bug#8664)
21354 * xselect.c (last_event_timestamp): Remove duplicate decl.
21355 (x_own_selection): Remove needless cast to unsigned long.
21357 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21358 that always fit in int. Use a sentinel instead of a counter, to
21359 avoid a temp and to allay GCC's concerns about possible int overflow.
21360 * frame.h (struct frame): Use int for menu_bar_items_used
21361 instead of EMACS_INT, since it always fits in int.
21363 * menu.c (grow_menu_items): Check for int overflow.
21365 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21367 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21368 Before, the code was not consistent. These values cannot exceed
21369 2**31 - 1 so there's no need to make them unsigned.
21370 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21371 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21372 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21374 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21376 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21377 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21378 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21379 presumably because the widths might not match.
21381 * window.c (size_window): Avoid needless test at loop start.
21383 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21385 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21387 2011-05-12 Drew Adams <drew.adams@oracle.com>
21389 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21391 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21393 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21394 `width' to `bar_area_x' and `bar_area_width', respectively.
21395 (x_scroll_run): Take account of fringe background extension.
21397 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21398 Rename local vars `left' and `width' to `bar_area_x' and
21399 `bar_area_width', respectively.
21400 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21401 background extension.
21403 2011-05-10 Jim Meyering <meyering@redhat.com>
21405 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21407 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21409 * image.c (Finit_image_library): Return t for built-in image types,
21410 like pbm and xbm. (Bug#8640)
21412 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21414 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21416 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21418 * w32console.c (Fset_screen_color): Doc fix.
21419 (Fget_screen_color): New function.
21420 (syms_of_ntterm): Defsubr it.
21422 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21423 unlink the temporary file if Fcall_process didn't create it in the
21425 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21426 child process will be redirected to a file specified with `:file'.
21427 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21428 cue to call_process_cleanup not to close that handle.
21430 2011-05-07 Ben Key <bkey76@gmail.com>
21432 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21433 one of two shell specific rules, either bootstrap-temacs-CMD or
21434 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21435 to the previous implementation of the bootstrap-temacs rule.
21436 The bootstrap-temacs-CMD rule is similar to the previous
21437 implementation of the bootstrap-temacs rule except that it
21438 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21441 These changes, along with some changes to nt/configure.bat,
21442 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21443 earlier fix to add support for --cflags and --ldflags options
21444 that include quotes so that it works whether make uses cmd or
21447 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21449 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21450 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21452 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21453 a string. Handle both cases.
21454 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21455 (Fdbus_register_method): Use Qinvalid_function.
21457 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21459 * makefile.w32-in: Update dependencies.
21460 (LISP_H): Add inttypes.h and stdin.h.
21461 (PROCESS_H): Add unistd.h.
21463 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21465 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21466 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21468 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21470 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21472 * term.c (vfatal): Remove stray call to va_end.
21473 It's not needed and the C Standard doesn't allow it here anyway.
21475 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21476 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21478 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21481 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21483 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21485 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21487 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21489 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21491 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21492 * charset.c (Fdefine_charset_internal): Don't initialize
21493 charset.code_space[15]. The value was garbage, on hosts with
21494 32-bit int (Bug#8600).
21496 * lread.c (read_integer): Be more consistent with string-to-number.
21497 Use string_to_number to do the actual conversion; this avoids
21498 rounding errors and fixes some other screwups. Without this fix,
21499 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21500 (digit_to_number): Move earlier, for benefit of read_integer.
21501 Return -1 if the digit is out of range for the base, -2 if it is
21502 not a digit in any supported base. (Bug#8602)
21504 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21506 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21507 to match comment at start of function. This also removes a
21508 GCC warning about overflow in a 32+64-bit port.
21510 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21512 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21513 Reported by Stefan Monnier in
21514 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21515 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21516 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21518 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21519 (EMACS_UINTPTR): Likewise, with uintptr_t.
21521 * lisp.h: Prefer 64-bit EMACS_INT if available.
21522 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21523 on 32-bit hosts that have 64-bit int, so that they can access
21525 However, temporarily disable this change unless the temporary
21526 symbol WIDE_EMACS_INT is defined.
21528 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21530 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21531 This removes an assumption that EMACS_INT and long are the same
21532 width as pointers. The assumption is true for Emacs porting targets
21533 now, but we want to make other targets possible.
21534 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21535 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21536 In the rest of the code, change types of integers that hold casted
21537 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21538 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21539 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21540 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21541 No need to cast type when ORing.
21542 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21543 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21544 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21545 assume EMACS_INT is the same width as char *.
21546 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21547 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21548 Remove no-longer-needed casts.
21549 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21550 (xg_tool_bar_help_callback, xg_make_tool_item):
21551 Use EMACS_INTPTR to hold an integer
21552 that will be cast to void *; this can avoid a GCC warning
21553 if EMACS_INT is not the same width as void *.
21554 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21555 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21556 (current_message_1, set_message_1):
21557 Use a local to convert to proper width without a cast.
21558 * xmenu.c (dialog_selection_callback): Likewise.
21560 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21561 Also, don't assume VALBITS / RAND_BITS is less than 5,
21562 and don't rely on undefined behavior when shifting a 1 left into
21564 * lisp.h (get_random): Change signature to match.
21566 * lread.c (hash_string): Use size_t, not int, for hash computation.
21567 Normally we prefer signed values; but hashing is special, because
21568 it's better to use unsigned division on hash table sizes so that
21569 the remainder is nonnegative. Also, size_t is the natural width
21570 for hashing into memory. The previous code used 'int', which doesn't
21571 retain enough info to hash well into very large tables.
21572 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21574 * dbusbind.c: Don't possibly lose pointer info when converting.
21575 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21576 Use XPNTR rather than XHASH, so that the high-order bits of
21577 the pointer aren't lost when converting through void *.
21579 * eval.c (Fautoload): Don't double-shift a pointer.
21581 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21583 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21585 * gnutls.c (DEF_GNUTLS_FN):
21586 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21588 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21590 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21593 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21595 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21596 New version that can reserve upto 2GB of heap space.
21598 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21600 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21602 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21604 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21605 `gnutls_certificate_set_x509_key_file'.
21607 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21609 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21610 Update dependencies.
21612 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21614 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21615 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21616 Remove unused parameter `fildes'.
21617 * process.c (read_process_output, send_process): Don't pass it.
21619 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21621 Fix previous change: the library cache is defined in w32.c.
21622 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21623 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21625 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21627 Implement dynamic loading of GnuTLS on Windows.
21629 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21630 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21631 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21634 * gnutls.c (Qgnutls_dll): Define.
21635 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21636 (gnutls_*): Declare function pointers.
21637 (init_gnutls_functions): New function to initialize function pointers.
21638 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21639 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21640 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21641 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21642 (emacs_gnutls_write, emacs_gnutls_read)
21643 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21644 (Fgnutls_available_p): New function.
21645 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21646 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21647 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21649 * image.c: Include w32.h.
21650 (Vimage_type_cache): Delete.
21651 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
21652 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21653 (w32_delayed_load): Move to w32.c.
21655 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21657 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21658 (w32_delayed_load): Move from image.c. When loading a library, record
21659 its filename in the :loaded-from property of the library id.
21660 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21661 Initialize and staticpro them.
21662 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21664 * process.c: Include lisp.h before w32.h, not after.
21665 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21666 instead of gnutls_record_check_pending.
21668 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21670 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21672 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21673 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21676 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21678 * xterm.c (x_set_frame_alpha): Do not set property on anything
21679 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21681 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21683 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21685 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21687 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21688 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
21689 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

21694 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
21695 (Qgnutls_bootprop_callbacks_verify): Make static.
21697 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
21699 * callproc.c: Indentation fixup.
21701 * sysdep.c (wait_for_termination_1): Make static.
21702 (wait_for_termination, interruptible_wait_for_termination):
21703 Move after wait_for_termination_1.
21705 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21707 * sysdep.c (interruptible_wait_for_termination): New function
21708 which is like wait_for_termination, but allows keyboard
21711 * callproc.c (Fcall_process): Add (:file "file") as an option for
21713 (Fcall_process_region): Ditto.
21715 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21717 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21718 rather than `XVECTOR (FOO)->size'.
21720 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21721 inttypes.h, as a gnulib replacement is used if it not available in
21724 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21726 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21727 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21728 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21730 * coding.c (coding_alloc_by_realloc): Error out if destination
21731 will grow beyond MOST_POSITIVE_FIXNUM.
21732 (decode_coding_emacs_mule): Abort if there isn't enough place in
21733 charbuf for the composition carryover bytes. Reserve an extra
21734 space for up to 2 characters produced in a loop.
21735 (decode_coding_iso_2022): Abort if there isn't enough place in
21736 charbuf for the composition carryover bytes.
21738 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21740 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21741 aborting when %lld or %lll format is passed.
21742 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21743 %llo or %llx format is passed. (Bug#8545)
21745 * window.c (window_scroll_line_based): Use a marker instead of
21746 simple variables to record original value of point. (Bug#7952)
21748 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21749 produced by %s or %c overflows available buffer space. (Bug#8545)
21751 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21753 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21754 (SIZE_MAX): Move defn after all includes, as they might #define it.
21756 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21758 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21760 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21762 * keyboard.c (Qdelayed_warnings_hook): Define.
21763 (command_loop_1): Run `delayed-warnings-hook'
21764 if Vdelayed_warnings_list is non-nil.
21765 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21766 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21768 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21770 * doprnt.c (doprnt): Don't return value smaller than the buffer
21771 size if the message was truncated. (Bug#8545).
21773 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21775 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21776 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21778 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21780 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21782 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21784 * makefile.w32-in: Update dependencies.
21786 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21788 Improve `doprnt' and its usage. (Bug#8545)
21789 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21790 `format_end'. Remove support for %l as a conversion specifier.
21791 Don't use xrealloc. Improve diagnostics when the %l size modifier
21792 is used. Update the commentary.
21794 * eval.c (verror): Simplify calculation of size_t.
21796 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21799 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21801 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21804 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21806 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21807 This makes this file independent of the recent pseudovector change.
21809 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21811 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21813 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21814 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21815 Remove unused local.
21816 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21818 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21819 GCC 4.6.0 optimizes based on type-based alias analysis.
21820 For example, if b is of type struct buffer * and v of type struct
21821 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21822 != &v->size, and therefore "v->size = 1; b->size = 2; return
21823 v->size;" must therefore return 1. This assumption is incorrect
21824 for Emacs, since it type-puns struct Lisp_Vector * with many other
21825 types. To fix this problem, this patch adds a new type struct
21826 vectorlike_header that documents the constraints on layout of vectors
21827 and pseudovectors, and helps optimizing compilers not get fooled
21828 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21829 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21830 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21832 (XSETPVECTYPE): Rewrite in terms of new macro.
21833 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21834 This is a bit clearer, and further avoids the possibility of
21835 undesirable aliasing.
21836 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21837 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21838 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21839 since Lisp_Subr is a special case (no "next" field).
21840 (ASIZE): Now uses header.size rather than size.
21841 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21842 to avoid the hassle of writing XVECTOR (foo)->header.size.
21843 (struct vectorlike_header): New type.
21844 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21845 object, to help avoid aliasing.
21846 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21847 (SUBRP): Likewise, since Lisp_Subr is a special case.
21848 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21849 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21850 (struct Lisp_Hash_Table): Combine first two members into a single
21851 struct vectorlike_header member. All uses of "size" and "next" members
21852 changed to be "header.size" and "header.next".
21853 * buffer.h (struct buffer): Likewise.
21854 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21855 * frame.h (struct frame): Likewise.
21856 * process.h (struct Lisp_Process): Likewise.
21857 * termhooks.h (struct terminal): Likewise.
21858 * window.c (struct save_window_data, struct saved_window): Likewise.
21859 * window.h (struct window): Likewise.
21860 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21861 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21862 * buffer.c (init_buffer_once): Likewise.
21863 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21865 * process.c (Fformat_network_address): Use local var for size,
21868 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21870 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21871 * data.c (atof): Remove decl; no longer used or needed.
21872 (digit_to_number): Move to lread.c.
21873 (Fstring_to_number): Use new string_to_number function, to be
21874 consistent with how the Lisp reader treats infinities and NaNs.
21875 Do not assume that floating-point numbers represent EMACS_INT
21876 without losing information; this is not true on most 64-bit hosts.
21877 Avoid double-rounding errors, by insisting on integers when
21878 parsing non-base-10 numbers, as the documentation specifies.
21879 * lisp.h (string_to_number): New decl, replacing ...
21880 (isfloat_string): Remove.
21881 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21882 (read1): Do not accept +. and -. as integers; this
21883 appears to have been a coding error. Similarly, do not accept
21884 strings like +-1e0 as floating point numbers. Do not report
21885 overflow for integer overflows unless the base is not 10 which
21886 means we have no simple and reliable way to continue.
21887 Break out the floating-point parsing into a new
21888 function string_to_number, so that Fstring_to_number parses
21889 floating point numbers consistently with the Lisp reader.
21890 (digit_to_number): Move here from data.c. Make it static inline.
21891 (E_CHAR, EXP_INT): Remove, replacing with ...
21892 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21893 (string_to_number): New function, replacing isfloat_string.
21894 This function checks for valid syntax and produces the resulting
21895 Lisp float number too. Rework it so that string-to-number
21896 no longer mishandles examples like "1.0e+". Use strtoumax,
21897 so that overflow for non-base-10 numbers is reported only when
21898 there's no portable and simple way to convert to floating point.
21900 * textprop.c (set_text_properties_1): Rewrite for clarity,
21901 and to avoid GCC warning about integer overflow.
21903 * intervals.h (struct interval): Use EMACS_INT for members
21904 where EMACS_UINT might cause problems. See
21905 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21906 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21907 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21909 (offset_intervals): Tell GCC not to worry about length overflow
21910 when negating a negative length.
21912 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21913 (overrun_check_free): Likewise.
21915 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21916 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21919 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21920 (gnutls_make_error): Rename local to avoid shadowing.
21921 (gnutls_emacs_global_deinit): ifdef out; not used.
21922 (Fgnutls_boot): Use const for pointer to readonly storage.
21923 Comment out unused local. Fix pointer signedness problems.
21925 * lread.c (openp): Don't stuff size_t into an 'int'.
21926 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21927 about possible signed overflow.
21929 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21930 (GDK_KEY_g): Don't define if already defined.
21931 (xg_prepare_tooltip): Avoid pointer signedness problem.
21932 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21934 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21935 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21937 * xfns.c (Fx_window_property): Simplify a bit,
21938 to make a bit faster and to avoid GCC 4.6.0 warning.
21939 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21941 * fns.c (internal_equal): Don't assume size_t fits in int.
21943 * alloc.c (compact_small_strings): Tighten assertion a little.
21945 Replace pEd with more-general pI, and fix some printf arg casts.
21946 * lisp.h (pI): New macro, generalizing old pEd macro to other
21947 conversion specifiers. For example, use "...%"pI"d..." rather
21948 than "...%"pEd"...".
21949 (pEd): Remove. All uses replaced with similar uses of pI.
21950 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21951 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21952 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21953 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21954 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21955 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21956 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21958 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21959 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21960 * print.c (safe_debug_print, print_object): Likewise.
21961 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21963 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21964 avoiding the 0 flag, which is not portable.
21965 * process.c (Fmake_network_process): Use pI to avoid cast.
21966 * region-cache.c (pp_cache): Likewise.
21967 * xdisp.c (decode_mode_spec): Likewise.
21968 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21969 behavior on 64-bit hosts with printf arg.
21970 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21971 (x_stop_queuing_selection_requests): Likewise.
21972 (x_get_window_property): Don't truncate byte count to an 'int'
21975 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21976 here, since it parses constructs like leading '-' and spaces,
21977 which are not wanted; and it overflows with large numbers.
21978 Instead, simply match F[0-9]+, which is what is wanted anyway.
21980 * alloc.c: Remove unportable assumptions about struct layout.
21981 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21982 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21983 (allocate_vectorlike, make_pure_vector): Use the new macros,
21984 plus offsetof, to remove unportable assumptions about struct layout.
21985 These assumptions hold on all porting targets that I know of, but
21986 they are not guaranteed, they're easy to remove, and removing them
21987 makes further changes easier.
21989 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21990 This doesn't fix a bug but makes the code clearer.
21991 (string_overrun_cookie): Now const. Use initializers that
21992 don't formally overflow signed char, to avoid warnings.
21993 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21994 can cause Emacs to crash when string overrun checking is enabled.
21995 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21996 multiple of sizeof (EMACS_INT); it need not be, if
21997 alignof(EMACS_INT) < sizeof (EMACS_INT).
21998 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
22000 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

22007 supposed to be handshaking. (Bug#8556)
22008 Reported by Paul Eggert <eggert@cs.ucla.edu>.
22010 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

22020 * alloc.c (check_sblock, check_string_bytes)
22021 (check_string_free_list): Convert to standard C.
22023 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
22025 * w32.c (emacs_gnutls_push): Fix typo.
22027 2011-04-25 Eli Zaretskii <eliz@gnu.org>
22029 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
22030 "cast to pointer from integer of different size".
22032 Improve doprnt and its use in verror. (Bug#8545)
22033 * doprnt.c (doprnt): Document the set of format control sequences
22034 supported by the function. Use SAFE_ALLOCA instead of always
22037 * eval.c (verror): Don't limit the buffer size at size_max-1, that
22038 is one byte too soon. Don't use xrealloc; instead xfree and
22041 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
22043 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
22046 * gnutls.c: Renamed global_initialized to
22047 gnutls_global_initialized. Added internals for the
22048 :verify-hostname-error, :verify-error, and :verify-flags
22049 parameters of `gnutls-boot' and documented those parameters in the
22050 docstring. Start callback support.
22051 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
22052 unless a fatal error occurred. Call gnutls_alert_send_appropriate
22053 on error. Return error code.
22054 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
22055 (emacs_gnutls_read): Likewise.
22056 (Fgnutls_boot): Return handshake error code.
22057 (emacs_gnutls_handle_error): New function.
22058 (wsaerror_to_errno): Likewise.

22066 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
22068 * process.c (wait_reading_process_output): Check if GnuTLS
22069 buffered some data internally if no FDs are set for TLS
22072 * makefile.w32-in (OBJ2): Add gnutls.$(O).

22079 display_replaced_before_p argument into display_replaced_p, to
22080 make it consistent with the commentary. Fix typos in the

22090 <menu_help_message, prev_menu_help_message>: Constify.
22091 (IT_menu_make_room): menu->help_text is now `const char **';
22094 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
22095 to changes in oldXMenu/XMenu.h from 2011-04-16.
22096 (struct XMenu): Declare `help_text' `const char **'.

22113 changes in globals.h immediately force recompilation.
22114 (TAGS): Depend on $(CURDIR)/m/intel386.h and
22115 $(CURDIR)/s/ms-w32.h.
22116 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

22119 (syms_of_character): Don't defsubr it.
22120 <char-direction-table>: Deleted.
22122 2011-04-23 Eli Zaretskii <eliz@gnu.org>
22124 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
22125 * doprnt.c: Include limits.h.
22126 (SIZE_MAX): New macro.
22127 (doprnt): Return a size_t value. 2nd arg is now size_t.
22128 Many local variables are now size_t instead of int or unsigned.
22129 Improve overflow protection. Support `l' modifier for integer
22130 conversions. Support %l conversion. Don't assume an EMACS_INT
22131 argument for integer conversions and for %c.
22133 * lisp.h (doprnt): Restore prototype.
22135 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
22136 $(SRC)/character.h.
22138 * Makefile.in (base_obj): Add back doprnt.o.
22140 * deps.mk (doprnt.o): Add back prerequisites.
22141 (callint.o): Depend on character.h.
22143 * eval.c (internal_lisp_condition_case): Include the handler
22144 representation in the error message.
22145 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
22146 when breaking from the loop.
22148 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
22150 * callint.c (Fcall_interactively): When displaying error message
22151 about invalid control letter, pass the character's codepoint, not
22152 a pointer to its multibyte form. Improve display of the character
22153 in octal and display also its hex code.
22155 * character.c (char_string): Use %x to display the (unsigned)
22156 codepoint of an invalid character, to avoid displaying a bogus

22358 ns_descriptor_to_entity that were caused by using free to
22359 deallocate memory blocks that were allocated by xmalloc (via

22725 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

22749 * xdisp.c (message_enable_multibyte): Now static.
22751 Declare Lisp_Object Q* variables to be 'static' if not exported.

22767 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22769 Make Emacs functions such as Fatom 'static' by default.
22770 This makes it easier for human readers (and static analyzers)
22771 to see whether these functions can be called from other modules.
22772 DEFUN now defines a static function. To make the function external
22773 so that it can be used in other C modules, use the new macro DEFUE.

22793 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22794 decls for now-static functions.
22795 * buffer.h (Fdelete_overlay): Remove decl.

22831 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22833 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init

22847 (overrun_check_free): Protoize.
22849 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22851 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22852 since callers should never pass a negative size.
22853 Change the signature to match that of plain 'read' and 'write'; see
22854 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22855 * lisp.h: Update prototypes of emacs_write and emacs_read.
22857 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22859 * xdisp.c (redisplay_window): Don't try to determine the character
22860 position of the scroll margin if the window start point w->startp
22861 is outside the buffer's accessible region. (Bug#8468)
22863 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22865 Fix write-region and its subroutines for buffers > 2GB.
22866 * fileio.c (a_write, e_write): Modify declaration of arguments and
22867 local variables to support buffers larger than 2GB.
22868 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22870 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22871 argument, local variables, and return value.
22873 * lisp.h: Update prototypes of emacs_write and emacs_read.
22875 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22877 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22879 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22881 Fix more problems found by GCC 4.6.0's static checks.
22883 * xdisp.c (vmessage): Use a better test for character truncation.
22885 * charset.c (load_charset_map): <, not <=, for optimization,
22886 and to avoid potential problems with integer overflow.
22887 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22888 * casetab.c (set_identity, shuffle): Likewise.
22889 * editfns.c (Fformat): Likewise.
22890 * syntax.c (skip_chars): Likewise.
22892 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22893 This also lets GCC 4.6.0 generate slightly better loop code.
22895 * callint.c (Fcall_interactively): <, not <=, for optimization.
22896 (Fcall_interactively): Count the number of arguments produced,
22897 not the number of arguments given. This is simpler and lets GCC
22898 4.6.0 generate slightly better code.
22900 * ftfont.c: Distingish more carefully between FcChar8 and char.
22901 The previous code passed unsigned char * to a functions like
22902 strlen and xstrcasecmp that expect char *, which does not
22903 conform to the C standard.
22904 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22905 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22906 char * when the C standard requires it.
22908 * keyboard.c (read_char): Remove unused var.
22910 * eval.c: Port to Windows vsnprintf (Bug#8435).
22911 Include <limits.h>.
22912 (SIZE_MAX): Define if the headers do not.
22913 (verror): Do not give up if vsnprintf returns a negative count.
22914 Instead, grow the buffer. This ports to Windows vsnprintf, which
22915 does not conform to C99. Problem reported by Eli Zaretskii.
22916 Also, simplify the allocation scheme, by avoiding the need for
22917 calling realloc, and removing the ALLOCATED variable.
22919 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22921 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22922 But keep the doprint source code for now, as we might revamp it
22923 and use it again (Bug#8435).
22924 * lisp.h (doprnt): Remove.
22925 * Makefile.in (base_obj): Remove doprnt.o.
22926 * deps.mk (doprnt.o): Remove.
22928 error: Print 32- and 64-bit integers portably (Bug#8435).
22929 Without this change, on typical 64-bit hosts error ("...%d...", N)
22930 was used to print both 32- and 64-bit integers N, which relied on
22931 undefined behavior.
22932 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22933 * lisp.h (error, verror): Mark as printf-like functions.
22934 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22935 Report overflow in size calculations when allocating printf buffer.
22936 Do not truncate output string at its first null byte.
22937 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22938 Truncate the output at a character boundary, since vsnprintf does not
22940 * charset.c (check_iso_charset_parameter): Convert internal
22941 character to string before calling 'error', since %c now has the
22943 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22944 overflow when computing char to be passed to 'error'. Do not
22945 pass Lisp_Object to 'error'; pass the integer instead.
22946 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22947 formatted with plain %d.
22949 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22951 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22953 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22955 * xterm.c (x_catch_errors): Remove duplicate declaration.
22957 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22959 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22961 2011-04-10 Jim Meyering <meyering@redhat.com>
22963 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22964 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22965 return ssize_t not "int", and use size_t as the buffer length.
22966 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22967 * gnutls.h: Update declarations.
22968 * process.c (read_process_output): Use ssize_t, to match.
22969 (send_process): Likewise.
22971 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22973 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22975 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22977 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22978 Use unsigned char, to match FcChar8 type definition.
22980 * xterm.c (handle_one_xevent):
22981 * xmenu.c (create_and_show_popup_menu):
22982 * xselect.c (x_decline_selection_request)
22983 (x_reply_selection_request): Avoid type-punned deref of X events.
22985 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22987 Fix some uses of `int' instead of EMACS_INT.
22988 * search.c (string_match_1, fast_string_match)
22989 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22990 (scan_buffer, find_next_newline_no_quit)
22991 (find_before_next_newline, search_command, Freplace_match)
22992 (Fmatch_data): Make some `int' variables be EMACS_INT.
22994 * xdisp.c (display_count_lines): 3rd argument and return value now
22995 EMACS_INT. All callers changed.
22996 (pint2hrstr): Last argument is now EMACS_INT.
22998 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22999 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

23015 (encode_invocation_designation): Last argument P_NCHARS is now
23017 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
23018 (produce_chars): from_nchars and to_nchars are now EMACS_INT.

23042 (Qhelp_form_show): New var.
23043 (syms_of_keyboard): Use DEFSYM macro.
23045 * print.c (internal_with_output_to_temp_buffer): Function deleted.

23058 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
23060 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
23062 Fix more problems found by GCC 4.6.0's static checks.
23064 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

23068 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
23070 * xdisp.c (vmessage): Mark as a printf-like function.
23072 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

23077 printf-like functions.
23078 (tiff_load): Add casts to remove these marks before passing them
23079 to system-supplied API.
23081 * eval.c (Fsignal): Remove excess argument to 'fatal'.
23083 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
23084 This avoids several warnings with gcc -Wstrict-overflow.
23085 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
23086 directly, rather than having caller test rule sign. This avoids
23087 some unnecessary tests.
23088 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
23089 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
23090 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
23092 * xfont.c (xfont_text_extents): Remove var that was set but not used.
23093 (xfont_open): Avoid unnecessary tests.
23095 * composite.c (composition_gstring_put_cache): Use unsigned integer.
23097 * composite.h, composite.c (composition_gstring_put_cache):
23098 Use EMACS_INT, not int, for length.
23100 * composite.h (COMPOSITION_DECODE_REFS): New macro,
23101 breaking out part of COMPOSITION_DECODE_RULE.
23102 (COMPOSITION_DECODE_RULE): Use it.
23103 * composite.c (get_composition_id): Remove unused local vars,
23104 by using the new macro.
23106 * textprop.c (set_text_properties_1): Change while to do-while,
23107 since the condition is always true at first.
23109 * intervals.c (graft_intervals_into_buffer): Mark var as used.
23110 (interval_deletion_adjustment): Return unsigned value.
23113 * process.c (list_processes_1, create_pty, read_process_output):
23114 (exec_sentinel): Remove vars that were set but not used.
23115 (create_pty): Remove unnecessary "volatile"s.
23116 (Fnetwork_interface_info): Avoid possibility of int overflow.
23117 (read_process_output): Do adaptive read buffering even if carryover.
23118 (read_process_output): Simplify nbytes computation if buffered.

23123 (update_syntax_table): Use unsigned instead of int.
23125 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
23126 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
23127 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
23129 * print.c (print_error_message): Avoid int overflow.
23131 * font.c (font_list_entities): Redo for clarity,
23132 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
23134 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
23135 (font_score): Avoid potential overflow in diff calculation.
23137 * fns.c (substring_both): Remove var that is set but not used.
23138 (sxhash): Redo loop for clarity and to avoid wraparound warning.
23140 * eval.c (funcall_lambda): Rename local to avoid shadowing.
23142 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
23143 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
23144 can always succeed if overflow has undefined behavior.
23146 * search.c (boyer_moore, wordify): Remove vars set but not used.
23147 (wordify): Omit three unnecessary tests.
23149 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
23150 All callers changed. This avoids the need for an unused var.
23152 * casefiddle.c (casify_region): Remove var that is set but not used.
23154 * dired.c (file_name_completion): Remove var that is set but not used.
23156 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23158 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23159 (Finsert_file_contents): Remove unnecessary code checking fd.
23161 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23162 Check for integer overflow on size calculations.
23164 * buffer.c (Fprevious_overlay_change): Remove var that is set
23167 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23168 Remove vars that are set but not used.
23169 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23170 (timer_check_2): Mark vars as initialized.
23172 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23174 * image.c (lookup_image): Remove var that is set but not used.
23175 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23177 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23178 that are set but not used.
23180 * xfns.c (make_invisible_cursor): Don't return garbage
23181 if XCreateBitmapFromData fails (Bug#8410).
23183 * xselect.c (x_get_local_selection, x_handle_property_notify):
23184 Remove vars that are set but not used.
23186 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
23187 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
23189 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
23190 Remove var that is set but not used.
23191 (scroll_bar_windows_size): Now size_t, not int.
23192 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23193 Check for overflow.
23195 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23196 (map_tty_color) [!defined MSDOS]: Likewise.
23198 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23200 * coding.c: Remove vars that are set but not used.
23201 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
23202 All callers changed.
23203 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
23204 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
23205 (decode_coding_charset): Remove vars that are set but not used.
23207 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
23208 that is set but not used.
23210 * print.c (print_object): Remove var that is set but not used.
23212 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23213 The gnulib version avoids calling malloc in the usual case,
23214 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23215 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23216 * filelock.c (current_lock_owner): Likewise.
23217 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23218 * sysdep.c: Include allocator.h, careadlinkat.h.
23219 (emacs_no_realloc_allocator): New static constant.
23220 (emacs_readlink): New function.
23221 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23222 ../lib/careadlinkat.h.
23224 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23226 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
23227 first non-nil return value).
23229 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
23231 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
23232 if not defined (Bug#8403).
23234 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23236 * xdisp.c (display_count_lines): Remove parameter `start',
23237 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23238 (get_char_face_and_encoding): Remove parameter `multibyte_p',
23239 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

23241 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
23242 and thereabouts. All callers changed.
23243 (get_per_char_metric): Remove parameter `f', unused since
23244 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
23246 2011-04-02 Jim Meyering <meyering@redhat.com>
23248 do not dereference NULL upon failed strdup
23249 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23250 (ns_get_family): Likewise.
23252 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23254 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23256 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23258 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23261 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23263 Add lexical binding.
23265 * window.c (Ftemp_output_buffer_show): New fun.
23266 (Fsave_window_excursion):
23267 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
23269 * lread.c (lisp_file_lexically_bound_p): New function.
23270 (Fload): Bind Qlexical_binding.
23271 (readevalloop): Remove `evalfun' arg.
23272 Bind Qinternal_interpreter_environment.
23273 (Feval_buffer): Bind Qlexical_binding.
23274 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23276 (syms_of_lread): Declare `lexical-binding'.
23278 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23280 * keyboard.c (eval_dyn): New fun.
23281 (menu_item_eval_property): Use it.
23283 * image.c (parse_image_spec): Use Ffunctionp.
23285 * fns.c (concat, mapcar1): Accept byte-code-functions.
23287 * eval.c (Fsetq): Handle lexical vars.
23288 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23289 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23290 (FletX, Flet): Obey lexical binding.
23291 (Fcommandp): Handle closures.
23292 (Feval): New `lexical' arg.
23293 (eval_sub): New function extracted from Feval. Use it almost
23294 everywhere where Feval was used. Look up vars in lexical env.
23296 (Ffunctionp): Move from subr.el.
23297 (Ffuncall): Handle closures.
23298 (apply_lambda): Remove `eval_flags'.
23299 (funcall_lambda): Handle closures and new byte-code-functions.
23300 (Fspecial_variable_p): New function.
23301 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23302 but without exporting it to Lisp.
23304 * doc.c (Fdocumentation, store_function_docstring):
23305 * data.c (Finteractive_form): Handle closures.
23307 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23310 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23312 (exec_byte_code): New function extracted from Fbyte_code to handle new
23313 calling convention for byte-code-functions. Add new byte-codes.
23315 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
23317 * alloc.c (Fmake_symbol): Init new `declared_special' field.
23319 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23321 * xdisp.c (redisplay_internal): Fix prototype.
23323 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23325 * xdisp.c (SCROLL_LIMIT): New macro.
23326 (try_scrolling): Use it when setting scroll_limit.
23327 Limit scrolling to 100 screen lines.
23328 (redisplay_window): Even when falling back on "recentering",
23329 position point in the window according to scroll-conservatively,
23330 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23332 (try_scrolling): When point is above the window, allow searching
23333 as far as scroll_max, or one screenful, to compute vertical
23334 distance from PT to the scroll margin position. This prevents
23335 try_scrolling from unnecessarily failing when
23336 scroll-conservatively is set to a value slightly larger than the
23337 window height. Clean up the case of PT below the margin at bottom
23338 of window: scroll_max can no longer be INT_MAX. When aggressive
23339 scrolling is in use, don't let point enter the opposite scroll
23340 margin as result of the scroll.
23341 (syms_of_xdisp) <scroll-conservatively>: Document the
23342 threshold of 100 lines for never-recentering scrolling.
23344 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23346 * dispextern.h (move_it_by_lines):
23347 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
23348 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
23349 (message_log_check_duplicate): Remove parameters `prev_bol' and
23350 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23351 (redisplay_internal): Remove parameter `preserve_echo_area',
23352 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23354 * indent.c (Fvertical_motion):
23355 * window.c (window_scroll_pixel_based, Frecenter):
23356 Don't pass `need_y_p' to `move_it_by_lines'.
23358 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23360 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23361 steal a few bits to be more compact.
23362 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23363 Remove unneeded casts.
23365 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23367 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23369 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23370 binding" message (bug#7967).
23372 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23374 Fix more problems found by GCC 4.6.0's static checks.
23376 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23377 Remove unused local var.
23379 * editfns.c (Fmessage_box): Remove unused local var.
23381 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23382 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23383 Omit unused local vars.
23384 * window.c (shrink_windows): Omit unused local var.
23385 * menu.c (digest_single_submenu): Omit unused local var.
23386 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23387 Omit unused local var.
23389 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23390 Don't assume string length fits in int.
23391 (keyremap_step, read_key_sequence): Use size_t for sizes.
23392 (read_key_sequence): Don't check last_real_key_start redundantly.
23394 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
23395 instead of alloca (Bug#8344).
23397 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23398 (Fbacktrace_frame): Don't assume nframes fits in int.
23400 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
23402 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
23405 * term.c (produce_glyphless_glyph): Remove unnecessary test.
23407 * cm.c (calccost): Turn while-do into do-while, for clarity.
23409 * keyboard.c (syms_of_keyboard): Use the same style as later
23410 in this function when indexing through an array. This also
23411 works around GCC bug 48267.
23413 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23415 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23417 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23418 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23420 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23421 This avoids undefined behavior on integer overflow, and is a bit
23422 more convenient anyway since it is compared to a size_t variable.
23424 Variadic C functions now count arguments with size_t, not int.
23425 This avoids an unnecessary limitation on 64-bit machines, which
23426 caused (substring ...) to crash on large vectors (Bug#8344).
23427 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
23428 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
23429 All variadic functions and their callers changed accordingly.

23436 * fns.c (concat): Likewise.
23437 * frame.c (x_set_frame_parameters): Likewise.
23438 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23439 0 if not found, not -1. All callers changed.
23441 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23442 (stack_copy_size): Now size_t, not int.
23443 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23445 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
23447 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
23448 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
23449 All callers changed.
23451 * lisp.h (multibyte_char_to_unibyte):
23452 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
23453 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
23454 * character.h (CHAR_TO_BYTE8):
23455 * cmds.c (internal_self_insert):
23456 * editfns.c (general_insert_function):
23457 * keymap.c (push_key_description):
23458 * search.c (Freplace_match):
23459 * xdisp.c (message_dolog, set_message_1): All callers changed.
23461 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
23463 * keyboard.c (safe_run_hook_funcall): New function.
23464 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23465 don't set the hook to nil, but remove the offending function instead.
23466 (Qcommand_hook_internal): Remove, unused.
23467 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
23468 Vcommand_hook_internal.
23470 * eval.c (enum run_hooks_condition): Remove.
23471 (funcall_nil, funcall_not): New functions.
23472 (run_hook_with_args): Call each function through a `funcall' argument.
23473 Remove `cond' argument, now redundant.
23474 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
23475 (Frun_hook_with_args_until_failure): Adjust accordingly.
23476 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
23478 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

23648 * buffer.c (Fkill_all_local_variables):
23649 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23651 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23652 unconditionally since it does the check itself.
23654 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23656 Fix more problems found by GCC 4.5.2's static checks.
23658 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23659 the first time through the loop, since we know p0 < p1 then.
23660 This also avoids a gcc -Wstrict-overflow warning.
23662 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23663 leading to a memory leak, possible in functions like
23664 load_charset_map_from_file that can allocate an unbounded number
23665 of objects (Bug#8318).
23667 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23668 that could (at least in theory) be that large.
23670 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23671 This is less likely to overflow, and avoids undefined behavior if
23672 overflow does occur. All callers changed. Use strtoul to scan
23673 for the unsigned long integer.
23674 (pint2hrstr): Simplify and tune code slightly.
23675 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

23690 * process.c (Fmake_network_process): Use socklen_t, not int,
23691 where POSIX says socklen_t is required in portable programs.
23692 This fixes a porting bug on hosts like 64-bit HP-UX, where
23693 socklen_t is wider than int (Bug#8277).
23694 (Fmake_network_process, server_accept_connection):
23695 (wait_reading_process_output, read_process_output):
23698 * process.c: Rename or move locals to avoid shadowing.

23708 Make tparam.h and terminfo.c consistent.
23709 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23710 Include tparam.h instead, since it declares them.
23711 * cm.h (PC): Remove extern decl; tparam.h now does this.
23712 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23713 * terminfo.c: Include tparam.h, to check interfaces.
23714 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23715 (tparam): Adjust signature to match interface in tparam.h;
23716 this removes some undefined behavior. Check that outstring and len
23717 are zero, which they always are with Emacs.
23718 * tparam.h (PC, BC, UP): New extern decls.
23720 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23721 (xftfont_open): Rename locals to avoid shadowing.

23739 (composition_update_it): Mark var as initialized.
23740 (find_automatic_composition): Mark vars as initialized,
23741 with a FIXME (Bug#8290).

23747 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23748 to avoid shadowing.

23760 Fix pointer signedness.
23761 (alsa_choose_format): Remove unused local var.
23762 (wav_play): Initialize a variable to 0, to prevent undefined
23763 behavior (Bug#8278).
23765 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23767 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23769 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23770 clobbering (Bug#8298).
23771 * sysdep.c (sys_subshell): Likewise.
23772 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23774 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23775 This should get cleaned up, so that child_setup has the
23776 same signature on all platforms.
23778 * callproc.c (call_process_cleanup): Now static.
23779 (relocate_fd): Rename locals to avoid shadowing.
23781 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23783 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23784 not to be necessary, and produces flickering.
23786 2011-03-20 Glenn Morris <rgm@gnu.org>
23788 * config.in: Remove file.
23790 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

23837 * unexelf.c (unexec): Name an expression,
23838 to avoid gcc -Wbad-function-cast warning.

23840 n rather than nn, a way that does not involve shadowing.
23841 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23843 * deps.mk (unexalpha.o): Remove; unused.

23932 Rename locals to avoid shadowing.
23933 (mark_stack): Move local variables into the #ifdef region where
23935 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
23936 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
23938 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23939 (GC_STRING_CHARS): Remove; not used.
23940 (Fmemory_limit): Cast sbrk's returned value to char *.
23942 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23943 avoids undefined behavior in theory.
23945 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23947 Use functions, not macros, for up- and down-casing (Bug#8254).
23948 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23949 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23950 to use the following functions instead of these macros.
23951 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23952 EMACS_INT, since callers assume the returned value fits in int.
23953 (upcase1): Likewise, for UPCASE_TABLE.
23954 (uppercasep, lowercasep, upcase): New static inline functions.
23955 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23956 the race-condition problem in the old DOWNCASE.
23958 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
23959 Rename locals to avoid shadowing.
23960 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
23961 (regex_compile, re_search_2, re_match_2_internal):
23962 Remove unused local vars.

23964 which gcc can warn about.
23965 (regex_compile, re_match_2_internal): Mark locals as initialized.
23966 (RETALLOC_IF): Define only if needed.
23967 (WORDCHAR_P): Likewise. This one is never needed, but is used
23968 only in a comment talking about a compiler bug, so put inside
23969 the #if 0 of that comment.
23970 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23971 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23974 * search.c (boyer_moore): Rename locals to avoid shadowing.
23975 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

23986 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
23988 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
23989 Rename locals to avoid shadowing.

23997 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23998 New macros, so that the caller can use some names other than
23999 gcpro1, gcpro2, etc.
24000 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
24002 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
24003 argument, for consistency with GCPRO2_VAR, etc: it is now the
24004 prefix of the variable, not the variable itself. All uses
24006 * dired.c (directory_files_internal, file_name_completion):
24007 Rename locals to avoid shadowing.
24009 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
24010 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
24011 dired.c's scmp function, had undefined behavior.
24012 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
24013 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
24014 * buffer.h: ... to here, because these macros use current_buffer,
24015 and the new implementation with inline functions needs to have
24016 current_buffer in scope now, rather than later when the macros
24018 (downcase, upcase1): New static inline functions.
24019 (DOWNCASE, UPCASE1): Reimplement using these functions.
24020 This avoids undefined behavior in expressions like
24021 DOWNCASE (x) == DOWNCASE (y), which previously suffered
24022 from race conditions in accessing the global variables
24023 case_temp1 and case_temp2.
24024 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
24025 * lisp.h (case_temp1, case_temp2): Remove their decls.
24026 * character.h (ASCII_CHAR_P): Move from here ...
24027 * lisp.h: ... to here, so that the inline functions mentioned
24028 above can use them.
24030 * dired.c (directory_files_internal_unwind): Now static.
24032 * fileio.c (file_name_as_directory, directory_file_name):
24033 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
24035 (file_name_as_directory): Use const pointers when appropriate.
24036 (Fexpand_file_name): Likewise. In particular, newdir might
24037 point at constant storage, so make it a const pointer.
24038 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
24039 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
24041 (Fset_file_times, Finsert_file_contents, auto_save_error):

24046 to avoid shadowing.
24048 * marker.c (bytepos_to_charpos): Remove; unused.
24050 * lisp.h (verify_bytepos, count_markers): New decls,
24051 so that gcc does not warn that these functions aren't declared.
24053 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
24054 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
24055 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
24056 (copy_text): Remove unused local var.
24058 * filelock.c (within_one_second): Now static.
24059 (lock_file_1): Rename local to avoid shadowing.
24061 * buffer.c (fix_overlays_before): Mark locals as initialized.
24062 (fix_start_end_in_overlays): Likewise. This function should be
24063 simplified by using pointers-to-pointers, but that's a different
24065 (switch_to_buffer_1): Now static.
24066 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
24067 (report_overlay_modification): Rename locals to avoid shadowing.
24069 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
24070 Fix pointer signedness issue.
24071 (sys_subshell): Mark local as volatile if checking for lint,
24072 to suppress a gcc -Wclobbered warning that does not seem to be right.
24073 (MAXPATHLEN): Define only if needed.
24075 * process.c (serial_open, serial_configure): Move decls from here ...
24076 * systty.h: ... to here, so that they can be checked.
24078 * fns.c (get_random, seed_random): Move extern decls from here ...
24079 * lisp.h: ... to here, so that they can be checked.
24081 * sysdep.c (reset_io): Now static.
24082 (wait_for_termination_signal): Remove; unused.
24084 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
24085 (copy_keymap_item, append_key, push_text_char_description):
24087 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.

24089 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
24090 (describe_map_tree):
24091 Rename locals to avoid shadowing.

24241 1152921504606846976) returns the obviously-bogus value (-948597
24242 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
24243 reports time overflow. See
