559 * insdel.c (insert_1_both): Document the arguments, instead of
560 referring to insert_1, which no longer exists.
562 * xdisp.c (message_dolog): If the *Messages* buffer is shown in

662 * xterm.h (GTK_PREREQ): New macro.
663 All simple uses of GTK_MAJOR_VERSION and GTK_MINOR_VERSION changed

666 2013-05-08 Eli Zaretskii <eliz@gnu.org>
668 * xdisp.c (row_for_charpos_p): New function, with code of
669 cursor_row_p, but accepts an additional argument CHARPOS instead
670 of using a hardcoded PT.
671 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
672 (row_containing_pos): Call row_for_charpos_p instead of partially
673 doing the same. Fixes cursor positioning under longlines-mode
674 when longlines-show-effect includes more than one newline, when
675 moving the cursor vertically up.

695 * unexelf.c: Don't assume ElfW (Half) fits in int.
696 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
697 when dealing with ElfW (Half) values, since they can exceed 2**31
698 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
699 (entry_address): Omit unused NUM arg. All uses changed.
701 2013-05-07 Juri Linkov <juri@jurta.org>

749 (x_get_monitor_attributes_xinerama): New functions.
750 (Fx_display_monitor_attributes_list): New primitive.
751 (syms_of_xfns): Defsubr it.
753 * xterm.h (x_display_info): Add Xatom_net_workarea and
754 Xatom_net_current_desktop.
756 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
757 and dpyinfo->Xatom_net_current_desktop.
759 2013-05-06 Eli Zaretskii <eliz@gnu.org>
761 * xdisp.c (pos_visible_p): Use the special code for finding the
762 beginning of a display property or overlay for any "replacing"
763 display property, not just for display strings. This solves
764 incorrect reporting of position by posn-at-point. (Bug#14241)
766 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
768 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
769 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
770 Verify that ElfW (Half) fits in int.
771 (fatal): Use same signature as lisp.h.
772 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
773 configure and build with -DUNEXELF_DEBUG without worrying about
774 other modules that use DEBUG.
775 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
776 possibly-wide integers now uses it instead of plain fprintf.
777 (entry_address): New function, which avoids problems with 32-bit
778 overflow on 64-bit hosts.
779 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
780 (round_up): Don't assume the remainder fits in int.
781 (find_section): Use bool for boolean. Simplify debug code.
782 (unexec): Don't assume file sizes fit in int or size_t.
783 Omit unnecessary trailing newline in 'fatal' format.
784 Use strerror rather than outputting decimal error number.
785 Remove unused code when emacs is not defined;
786 this file relies on Emacs now.
787 Don't assume e_phnum and e_shnum are positive.
789 * regex.c: Fix problems when DEBUG is defined.
790 (extract_number, extract_number_and_incr): Define regardless of
791 whether DEBUG is defined; that's simpler and makes the code less
792 likely to go stale in the normal case when DEBUG is not defined.
793 Return int rather than taking an int * arg. All callers changed.
794 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
795 Remove, replacing with ...
796 (DEBUG_PRINT): New macro. All callers changed.
797 (DEBUG_COMPILES_ARGUMENTS): New macro.
798 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
799 (print_compiled_pattern, print_double_string) [DEBUG]:
800 Use prototype rather than old-style definition.
801 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
802 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
803 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
804 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
805 Don't assume ptrdiff_t, size_t, and long are the same width as int.
806 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
807 This matters only when DEBUG is defined.
809 2013-05-05 Eli Zaretskii <eliz@gnu.org>
811 * xdisp.c (set_iterator_to_next): Set the
812 ignore_overlay_strings_at_pos_p flag only if we are _really_
813 iterating over an overlay string, as indicated by the
814 current.overlay_string_index member. (Bug#14306)
816 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
818 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
819 to where it is used, to avoid autorelease issues (Bug#14050).
821 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
823 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
824 * fileio.c (syms_of_fileio): Implement this.
825 * filelock.c (create_lock_file): If symbolic links don't work, so
826 we use a regular file as a lock file, do not fsync the lock file;
829 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
831 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.
832 (syms_of_minibuf): Adjust accodingly.
834 * callint.c (Fcall_interactively): Adjust calls accordingly.
836 2013-05-04 Eli Zaretskii <eliz@gnu.org>
838 * dispextern.h (WINDOW_WANTS_HEADER_LINE_P): Verify that
839 w->contents is a buffer before computing everything else.
840 Use parentheses to disambiguate last part of the condition.
842 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
843 assertion violations. (Bug#14062)
845 2013-05-01 David Reitter <david.reitter@gmail.com>
847 * nsfns.m (ns_tooltip): Initialize.
849 2013-04-28 Eli Zaretskii <eliz@gnu.org>
851 * coding.c (decode_coding_gap): Don't remove the character before
852 a newline unless it's a CR character. (Bug#14287)
854 2013-04-28 Dan Nicolaescu <dann@gnu.org>
856 * dispextern.h (struct face): Move enum face_underline_type
857 earlier so that bitfields can be in the same word.
859 2013-04-28 Jan Djärv <jan.h.d@swipnet.se>
861 * nsfns.m (handlePanelKeys): New function.
862 (EmacsOpenPanel:performKeyEquivalent:)
863 (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle
864 arrows/function/control and copy/paste keys (Bug#14296).
866 2013-04-27 Juri Linkov <juri@jurta.org>
868 * callint.c (Fcall_interactively): Call `Qread_number' for
869 interactive code letter `n' instead of using duplicate code.
872 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
874 * systime.h (make_timeval): Declare as 'const'.
876 2013-04-27 Kenichi Handa <handa@gnu.org>
878 * font.c (font_open_entity): Always open a font of manageable
881 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
883 Port better to AIX (Bug#14258).
884 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
887 2013-04-24 Kenichi Handa <handa@gnu.org>
889 * coding.c (decode_coding_iso_2022): When an invalid escape
890 sequence is encountered, reset the invocation and designation
891 status to the safest one.
893 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
895 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
896 Without this fix, "make distclean" leaves stamp-h1 behind.
898 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
900 * w32fns.c (w32_fullscreen_rect): New function to compute the
901 window rectangle for the given fullscreen mode.
902 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
903 longer tunes the window size. This keeps the window's edges flush
904 with the screen and allows the taskbar to hide itself in fullboth.
906 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
907 window decorations and uses the entire screen.
909 * w32term.h (w32_fullscreen_rect) Add prototype.
910 (struct w32_output): Replace normal_width, normal_height,
911 normal_top, and normal_left members with a single normal_placement
913 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):

917 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
919 * minibuf.c (Ftest_completion): Silence compiler warning.
921 2013-04-15 Eli Zaretskii <eliz@gnu.org>
923 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
926 * frame.h (WINDOW_FRAME): Protect macro and its argument with
929 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
930 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
931 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
932 parentheses where appropriate.
934 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
936 * keyboard.c (timer_start_idle): Remove no-longer-used local.
938 2013-04-14 Eli Zaretskii <eliz@gnu.org>
940 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
941 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
942 Mention in the doc string that setting these variables takes
943 effect only after a call to set-window-buffer. (Bug#14200)
945 2013-04-13 Eli Zaretskii <eliz@gnu.org>
947 * indent.c (Fvertical_motion): Don't consider display strings on
948 overlay strings as display strings on the buffer position we
949 started from. This prevents vertical cursor motion from jumping
950 more than one line when there's an overlay string with a display
951 property at end of line.
952 Reported by Karl Chen <Karl.Chen@quarl.org> in
953 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

958 already selected (bug#14191).
960 2013-04-11 Eli Zaretskii <eliz@gnu.org>
962 * window.c (Fwindow_end): Test more flags, including the buffer's
963 last_overlay_modified flag, to determine whether the window's
964 display is really up-to-date. Prevents the function from
965 returning a stale value. (Bug#14170)
966 (Fwindow_line_height): Fix the test for up-to-date-ness of the
969 2013-04-10 Eli Zaretskii <eliz@gnu.org>
971 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
972 garbaged only if it is not already the top frame on its TTY.
973 This prevents flickering due to constant redrawing of TTY frames when
974 there are GUI frames open in the same session. (Bug#13864)
976 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
978 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
979 of marking the idle timers directly.
981 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
983 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
986 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>
988 * window.c (select_window): Don't record_buffer while the invariant is
989 temporarily broken (bug#14161).
991 * fns.c (Fdelq): Don't assume !NILP => CONSP.
993 2013-04-07 Eli Zaretskii <eliz@gnu.org>
995 * fileio.c (ACL_NOT_WELL_SUPPORTED): Define macro for WINDOWSNT.

1014 due to a profiler signal.
1015 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
1016 with these flags. On platforms where special flags are needed
1017 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.

1224 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
1225 (expose_window_tree): Likewise.
1226 Use contents slot, not buffer, where appropriate.
1227 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1228 to avoid deleted windows. Use contents slot instead of buffer.
1229 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:

1458 (XSAVE_OBJECT): Now functions, not macros.
1459 (STRING_BYTES_BOUND): Now just a macro, not a constant too;

1566 * coding.c (detect_ascii): New function.
1567 (detect_coding): Set coding->head_ascii and coding->eol_seen only

1628 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1630 * xdisp.c (init_iterator): Simplify because both character and byte
1631 positions are either specified or -1. Add eassert. Adjust comment.
1632 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1633 character and byte positions can be obtained from marker.

1653 Include <sys/param.h> unconditionally, as that works elsewhere and
1654 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1655 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

1687 common file dialog code.
1689 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which

1894 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1895 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1896 * bidi.c (bidi_find_paragraph_start): Likewise.
1897 * indent.c (vmotion): Likewise.
1899 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1901 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1902 * filelock.c: Include <c-ctype.h>.
1903 (MAX_LFINFO): New top-level constant.
1904 (lock_info_type): Remove members pid, boot_time. Add members at,
1905 dot, colon. Change user member to be the entire buffer, not a
1906 pointer. This allows us to handle the case where a foreign
1907 pid or boot time exceeds the local range. All uses changed.
1908 (LINKS_MIGHT_NOT_WORK): New constant.
1909 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1910 (defined_WINDOWSNT): Remove.
1911 (MAKE_LOCK_NAME, file_in_lock_file_name):
1912 Always use .#FILE (not .#-FILE) for the file lock,
1913 even if it is a regular file.
1914 (rename_lock_file): New function.
1915 (create_lock_file): Use it.
1916 (create_lock_file, read_lock_data):
1917 Prefer a symbolic link for the lock file, falling back on a
1918 regular file if symlinks don't work. Do not try to create
1919 symlinks on MS-Windows, due to security hassles. Stick with
1920 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1921 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1922 host may be using a Windowsish file system, and cannot use
1923 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1924 doesn't work. Don't fail merely because of a symlink-contents
1925 length limit in the current file system; fall back on regular
1926 files. Increase the symlink contents length limit to 8 KiB, this
1927 should be big enough for any real use and doesn't crunch the
1929 (create_lock_file, lock_file_1, read_lock_data):
1930 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1931 (lock_file_1): Return error number, not bool. All callers changed.
1932 (ELOOP): New macro, if not already defined.
1933 (read_lock_data): Return size of lock file contents, not Lisp object.
1934 All callers changed. Handle a race condition if some other process
1935 replaces a regular-file lock with a symlink lock or vice versa,
1936 while we're trying to read the lock.
1937 (current_lock_owner): Parse contents more carefully, to help avoid
1938 confusing a regular-file lock with some other application's use
1939 of the file. Check for lock file contents being too long, or
1940 not parsing correctly.
1941 (current_lock_owner, lock_file):
1942 Allow foreign pid and boot times that exceed the local range.
1943 (current_lock_owner, lock_if_free, lock_file):
1944 Simplify allocation of lock file contents.
1945 * w32.c (sys_rename_replace): New function, containing most of
1946 the contents of the old sys_rename.
1947 (sys_rename): Use it.
1948 (fchmod): New dummy function.
1949 * w32.h (sys_rename_replace, fchmod): New decls.
1951 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1953 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1954 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1955 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1956 <dmantipov@yandex.ru>.
1958 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1960 * composite.c (get_composition_id, fill_gstring_header):
1961 Use make_uninit_vector where appropriate.
1962 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1963 * xselect.c (clean_local_selection_data): Likewise.
1965 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1967 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1968 * image.c (imagemagick_load_image): Calculate height and width
1969 after flattening the image, not before.
1971 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1973 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1974 * ftfont.c (ftfont_shape_by_flt): Likewise.
1975 * w32uniscribe.c (uniscribe_shape): Likewise.
1977 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1979 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1980 The old approach, which fell back on DIR/.#FILE.0 through
1981 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1982 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1983 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1984 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1985 because the locking mechanism was never reliable in that case).
1986 This patch fixes this and other bugs discovered by a code
1987 inspection that was prompted by
1988 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1989 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1990 to avoid interoperability problems between the MS-Windows and
1991 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1992 instances of Emacs now ignore each others' locks.
1993 * filelock.c (defined_WINDOWSNT): New constant.
1994 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1995 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1996 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1997 regular files on MS-Windows hosts.
1998 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1999 Use SAFE_ALLOCA to avoid problems with long file names.
2000 (MAX_LFINFO): Now a local constant, not a global macro.
2001 (IS_LOCK_FILE): Remove.
2002 (lock_file_1): Don't inspect errno if symlink call succeeds;
2003 that's not portable.
2004 (lock_file): Document that this function can return if lock
2006 (lock_file): Don't access freed storage.
2008 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
2010 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
2012 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
2014 * textprop.c: Use bool for booleans.
2015 (validate_interval_range, Fadd_text_properties)
2016 (Fremove_text_properties): Prefer bool to int when either works.
2018 2013-03-02 Eli Zaretskii <eliz@gnu.org>
2020 * textprop.c (Fadd_text_properties, Fremove_text_properties):
2021 If the interval tree changes as a side effect of calling
2022 modify_region, re-do processing starting from the call to
2023 validate_interval_range. (Bug#13743)
2025 2013-02-28 Eli Zaretskii <eliz@gnu.org>
2027 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
2030 2013-02-27 Eli Zaretskii <eliz@gnu.org>
2032 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
2033 _SH_DENYRW flag, instead of emacs_open, to deny any other process
2034 access to the lock file until it is written and closed.
2037 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
2039 * callint.c (Qcall_interactively):
2040 * macros.c (Qexecute_kbd_macro):
2043 2013-02-26 Bastien Guerry <bzg@gnu.org>
2045 * window.c (Frecenter): Tiny docstring enhancement.
2047 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
2049 Minor textprop integer cleanup.
2050 * intervals.h, textprop.c (add_text_properties_from_list):
2051 Return void, not int, since nobody uses the return value.
2052 * textprop.c (validate_plist, add_properties, remove_properties)
2053 (Fadd_text_properties):
2054 Don't assume list length fits in int.
2055 (interval_has_all_properties, interval_has_some_properties)
2056 (interval_has_some_properties_list, add_properties, remove_properties)
2057 (Fadd_text_properties, Fremove_text_properties)
2058 (Fremove_list_of_text_properties, text_property_stickiness):
2059 Use bool for booleans.
2060 (Fadd_text_properties, Fremove_text_properties):
2061 (Fremove_list_of_text_properties):
2062 Reindent do-while as per GNU style.

2066 Implement CLASH_DETECTION for MS-Windows.
2068 * filelock.c [WINDOWSNT]: Include w32.h.
2069 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
2070 function of that name. Up-case the macro arguments.
2071 (IS_LOCK_FILE): New macro.
2072 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
2073 (create_lock_file): New function, with body extracted from
2075 [WINDOWSNT]: Implement lock files by writing a regular file with
2076 the lock information as its contents.
2077 (read_lock_data): New function, on Posix platforms just calls
2079 [WINDOWSNT]: Read the lock info from the file.
2080 (current_lock_owner): Call read_lock_data instead of calling
2081 emacs_readlinkat directly.
2082 (lock_file) [WINDOWSNT]: Run the file name through
2085 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
2086 just check if the process by that PID exists.
2088 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
2089 also present, as doing so will fail to error out if the file
2092 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
2094 * textprop.c (Fadd_text_properties, Fremove_text_properties)
2095 (Fremove_list_of_text_properties): Skip all of the intervals in
2096 the region between START and END that already have resp. don't
2097 have the requested properties, not just the first one.
2098 Add assertions that the loop afterwards always modifies the
2099 properties. (Bug#13743)

2111 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
2112 (START_FILES): Remove. All uses removed.
2113 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.

2129 * vm-limit.c: Move most of mem-limits.h's contents here.
2130 (data_start): New decl. It's OK if this is approximate,
2131 so simplify-away some unnecessary exactness.
2132 (POINTER): Remove; all uses removed.
2133 (data_space_start): Now char *, to avoid casts.
2134 (exceeds_lisp_ptr): New function, replacing the old

2150 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
2151 and diagnosed by Andreas Schwab in
2152 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
2154 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
2156 Assume C89 or better.
2157 * ralloc.c (SIZE, POINTER, NIL):
2158 * vm-limit.c (POINTER):
2159 Remove, replacing all uses with C89 equivalents. These old
2160 symbols were present only for porting to pre-C89 platforms.

2283 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2285 Fix AIX port (Bug#13650).
2286 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2287 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2288 was #undeffed earlier, so it cannot be used as a macro here.
2289 Use the constant and not the macro.
2291 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2293 * w32proc.c (new_child): If no vacant slots are found in
2294 child_procs[], make another pass looking for slots whose process
2295 has exited or died. (Bug#13546)

2298 MAXDESC, set errno to EMFILE.
2299 (_sys_read_ahead): Update cp->status when failing to read serial
2300 communications input, so that the status doesn't stay at
2301 STATUS_READ_IN_PROGRESS. (Bug#13546)
2303 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>

2329 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2331 Improve AIX port some more (Bug#13650).
2332 With this, it should be as good as it was in 23.3, though it's
2333 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2334 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2335 * unexaix.c (start_of_text): Remove.
2336 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2337 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2338 (orig_load_scnptr, orig_data_scnptr):
2339 Now off_t, not long, since they are file offsets.
2340 (make_hdr): Use _data, not start_of_data ().
2341 This is the key part of the fix.
2342 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2343 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2345 * pre-crt0.c (data_start): Initialize to 1.
2346 This ports to compilers that optimize the external declaration
2347 'int x = 0;' as if it were 'int x;' to shrink the executable.
2349 Improve AIX port (Bug#13650).
2350 This doesn't fix the bug, but it makes progress: Emacs builds now.
2351 * unexaix.c: Include inttypes.h, stdarg.h.
2352 (report_error, report_error_1): Mark as _Noreturn.
2353 (report_error): Don't report the wrong errno.
2354 (report_error_1): Now varargs. All callers changed.
2355 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2356 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2357 (write_ptr): Use %p to print address rather than %lx and a cast
2358 to unsigned long. Grow buffer a bit, to be safer.
2360 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2362 * bidi.c (bidi_resolve_neutral): After finding the next
2363 non-neutral character, accept NEUTRAL_ON type as well, because
2364 directional control characters, such as LRE and RLE, have their
2365 type converted to that by bidi_resolve_weak. This avoids aborts
2366 when LRE/RLE follows a run of neutrals.
2367 (bidi_move_to_visually_next): Assert that return value of
2368 bidi_peek_at_next_level is non-negative. Negative values will
2371 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2373 Minor getenv-related fixes.
2374 * callproc.c (Fcall_process_region) [!DOS_NT]:

2379 Omit unnecessary cast of getenv or egetenv.
2381 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
2383 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2384 Update dependencies.
2386 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2388 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2390 (display_line): Set w->region_showing to the value of
2391 it->region_beg_charpos, not to -1. This fixes redisplay
2392 optimization when cursor is moved up after M->. (Bug#13623)
2394 (try_scrolling): Scroll text up more if point is too close to ZV
2395 and inside the scroll margin. This makes sure point is moved
2396 outside the scroll margin in these cases.
2398 * window.h (struct window): region_showing can no longer be
2401 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2403 Tune by using memchr and memrchr.
2404 * doc.c (Fsnarf_documentation):
2405 * fileio.c (Fsubstitute_in_file_name):
2406 * search.c (find_newline, scan_newline):
2407 * xdisp.c (pos_visible_p, display_count_lines):
2408 Use memchr and memrchr rather than scanning byte-by-byte.
2409 * search.c (find_newline): Rename from scan_buffer.
2410 Omit first arg TARGET, as it's always '\n'. All callers changed.
2412 Clean up read_key_sequence a tiny bit more.
2413 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2414 (read_key_sequence): Remove unused locals.
2416 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2418 Clean up read_key_sequence a bit; reread active keymaps after first event.
2419 * keyboard.c (read_char, read_char_x_menu_prompt)
2420 (read_char_minibuf_menu_prompt):
2421 Replace nmaps+maps with a single `map' arg.
2422 (follow_key): Operate on a single map.
2423 (active_maps): New function.
2424 (test_undefined): Also return true for nil bindings.
2425 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2426 a single (composed) keymap. Remember `first_event' to choose the right
2427 set of active keymaps. Recompute the set of keymaps after receiving
2428 the first event. Remove GOBBLE_FIRST_EVENT.
2429 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2430 * keyboard.h (read_char): Update declaration.
2431 * lread.c (read_filtered_event): Adjust call to read_char.
2433 2013-02-11 Eli Zaretskii <eliz@gnu.org>
2435 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2436 Don't use the limitation on backwards movement when lines are truncated
2437 in the window. (Bug#13675)
2439 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2441 * marker.c (set_marker_internal): If desired position is passed
2442 as a marker, avoid call to buf_charpos_to_bytepos.
2443 * window.c (Fset_window_point): Omit redundant type checking.
2444 (Fset_window_start): Likewise. Format comment.
2445 (window_scroll_pixel_based): Use set_marker_restricted_both
2446 with character and byte positions obtained from an iterator.
2447 (Fset_window_configuration): Use set_marker_restricted_both.
2448 * xdisp.c (message_dolog): Likewise.
2450 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2452 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2453 When text lines are longer than window's screen lines, don't move back
2454 too far. This speeds up some redisplay operations. (Bug#13675)
2456 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2458 * syntax.c (scan_sexps_forward): Fix byte position calculation
2459 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
2461 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
2463 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
2464 that was not needed.
2466 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2468 Minor hashing refactoring.
2469 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2470 (sxhash_float): Return EMACS_UINT, for consistency with the other
2472 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2473 non-static inline function and therefore can't use static vars.
2474 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2475 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2476 with the other hash functions.
2478 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2480 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2481 XXXXXX part of the temporary file pattern is not downcased even
2482 when w32-downcase-file-names is non-nil. (Bug#13661)
2484 * xdisp.c (decode_mode_spec): Remove handling of %t.
2486 * msdos.c (careadlinkatcwd): Remove.
2488 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2490 * lread.c (skip_dyn_bytes): New function (bug#12598).
2491 (read1): Use it. Use getc instead of READCHAR to read bytes.
2492 (load_each_byte): Remove. Update users.
2494 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2496 * search.c (scan_buffer): Calculate end byte position just once.

2500 (scan_sexps_forward): Record from_byte and avoid redundant
2501 character to byte position calculation ...
2502 (Fparse_partial_sexp): ... here. Break too long line.
2504 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2506 * lisp.h (make_uninit_vector): New function.
2507 * alloc.c (Fvector, Fmake_byte_code):

2511 * composite.c (syms_of_composite):
2512 * font.c (Fquery_font, Ffont_info, syms_of_font):
2513 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
2514 * ftfont.c (ftfont_shape_by_flt):
2515 * indent.c (recompute_width_table):
2516 * nsselect.m (clean_local_selection_data):
2517 * syntax.c (init_syntax_once):
2518 * w32unsubscribe.c (uniscribe_shape):
2519 * window.c (Fcurrent_window_configuration):
2520 * xfaces.c (Fx_family_fonts):
2521 * xselect.c (selection_data_to_lisp_data): Use it.
2523 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
2525 * coding.c (Fdefine_coding_system_internal): Use AREF where
2526 argument is known to be a vector.
2527 * fns.c (Flocale_info): Likewise for ASET.
2528 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2529 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2531 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2533 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2536 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
2537 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
2538 updateCollectionBehaviour.
2540 * nsterm.m (NEW_STYLE_FS): Remove.
2541 (ns_last_use_native_fullscreen): New variable.
2542 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2543 (x_set_window_size): Do not take title bar and tool bar into account
2544 if isFullscreen returns YES.
2545 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2546 (check_native_fs): New function.
2547 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
2548 (ns_term_init): Remove NEW_STYLE_FS.
2549 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
2550 and tool bar if isFullscreen returns NO.
2551 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2552 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2553 with HAVE_NATIVE_FS.
2554 (window:willUseFullScreenPresentationOptions:): New method.
2555 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
2556 Hide toolbar if not enabled (Bug#13444).

2559 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
2560 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
2561 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
2562 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
2563 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2564 (syms_of_nsterm): Add ns-use-native-fullscreen.
2566 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2568 * fileio.c (Qchoose_write_coding_system): Now static.
2570 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2572 * xdisp.c (window_buffer_changed): region_showing can be negative,
2573 which still means region is being displayed.
2574 (redisplay_internal): Resurrect code that forced redisplay of the
2575 whole window when showing region and the mark has changed.
2576 Record the new mark position to allow redisplay optimizations.
2577 (display_line): If it->region_beg_charpos is non-zero, set the
2578 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2580 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2581 not bitfield of 1 bit.
2583 2013-02-03 Daniel Colascione <dancol@dancol.org>
2585 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2586 daemon mode works on cygw32 when Emacs is installed and not just
2589 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2591 Avoid file time stamp bug on MS-Windows (Bug#13149).
2592 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2593 as FAT32 doesn't update time stamps when truncating them.
2594 Also, check that a file time stamp is not a multiple of 100 ns;
2595 this should catch all instances of the problem on MS-Windows,
2596 as its native file system resolution is 100 ns or worse, and
2597 checking for a non-multiple of 100 ns should impose only a small
2598 overhead on systems with ns resolution.
2600 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2602 Avoid encoding file names on MS-Windows when they need to be run
2603 through dostounix_filename.
2604 * w32.c (normalize_filename): Accept an additional argument
2605 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2606 downcase it even if w32-downcase-file-names is non-nil.
2607 (dostounix_filename): Accept an additional argument MULTIBYTE and
2608 pass it to normalize_filename.
2609 (emacs_root_dir): Adjust.
2611 * msdos.h (dostounix_filename): Adjust prototype.
2613 * w32.h (dostounix_filename): Adjust prototype.
2615 * msdos.c (dostounix_filename): Accept an additional argument and
2617 (init_environment): Adjust callers of dostounix_filename.
2619 * fileio.c (Ffile_name_directory, file_name_as_directory)
2620 (directory_file_name, Fexpand_file_name)
2621 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2623 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2625 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2626 variables, as egetenv is case-insensitive for DOS_NT.
2628 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2629 with an encoded file name.
2631 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2632 Adjust calls to dostounix_filename.
2634 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2636 * unexw32.c (unexec): Adjust call to dostounix_filename.
2638 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2640 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2643 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2646 * callproc.c (Fcall_process): Make sure program name in PATH and
2647 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2648 is passed to exec/spawnve, which fails unless the file-name
2651 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2652 even if w32-quote-process-args is nil.
2654 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2656 Fix timestamp bug when write-region appends nothing (Bug#13149).
2657 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2658 the file's time stamp doesn't change if Emacs happens to write nothing
2659 to the file, and on a buggy file system this could cause Emacs to
2660 incorrectly infer that the file system doesn't have the bug.
2661 Avoid this problem by inhibiting the inference in this case.
2663 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2665 * window.h (struct window): Convert base_line_number, base_line_pos
2666 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2667 Convert region_showing member from Lisp_Object to bitfield.
2668 Remove sequence_number member. Adjust comments.
2669 * window.c (sequence_number): Remove.
2670 (make_window): Initialize column_number_displayed.
2671 * print.c (print_object): Follow the printed representation of
2672 frames and print window pointer to distinguish between windows.
2673 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2674 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2675 (wset_column_number_displayed, wset_region_showing): Remove.
2676 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2677 (try_scrolling, try_cursor_movement, redisplay_window)
2678 (try_window_reusing_current_matrix, try_window_id, display_line)
2679 (display_mode_lines, decode_mode_spec): Adjust users.
2680 * .gdbinit (pwinx): Do not print sequence_number.
2682 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2684 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2685 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2686 * dired.c: Include <fcntl.h>.
2687 (open_directory): New function, which uses open and fdopendir
2688 rather than opendir. DOS_NT platforms still use opendir, though.
2689 (directory_files_internal, file_name_completion): Use it.
2690 (file_attributes): New function, with most of the old Ffile_attributes.
2691 (directory_files_internal, Ffile_attributes): Use it.
2692 (file_attributes, file_name_completion_stat): First arg is now fd,
2693 not dir name. All uses changed. Use fstatat rather than lstat +
2695 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2696 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2697 (emacs_readlinkat): New function, with much of the old
2698 Ffile_symlink_p, but with an fd argument for speed.
2699 It uses readlinkat rather than careadlinkatcwd, so that it
2700 need not assume the working directory.
2701 (Ffile_symlink_p): Use it.
2702 * filelock.c (current_lock_owner): Use emacs_readlinkat
2703 rather than emacs_readlink.
2704 * lisp.h (emacs_readlinkat): New decl.
2705 (READLINK_BUFSIZE, emacs_readlink): Remove.
2706 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2707 (emacs_norealloc_allocator, emacs_readlink): Remove.
2708 This stuff is moved to fileio.c.
2709 * w32.c (fstatat, readlinkat): New functions.
2710 (careadlinkat): Don't check that fd == AT_FDCWD.
2711 (careadlinkatcwd): Remove; no longer needed.
2713 2013-01-31 Glenn Morris <rgm@gnu.org>
2715 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2716 (Fwrite_region): Update for new choose_write_coding_system args.
2717 Move the last piece of choose_write_coding_system here. (Bug#13522)
2718 (syms_of_fileio): Add choose-write-coding-system.
2720 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2722 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2723 (sys_close): Zero out the flags for the file descriptor before
2724 closing it. (Bug#13546)
2726 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2727 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2728 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2731 * w32.c (w32_get_long_filename, init_environment, readlink):
2732 Support file names encoded in DBCS codepages.
2733 (readlink): Use the current file-name-coding-system, not the ANSI
2734 codepage, to decode and handle targets of symlinks.
2736 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2738 * w32.c (opendir): Now accepts a 'const char *'.
2740 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2742 Remove obsolete redisplay code. See the discussion at
2743 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2744 * dispnew.c (preemption_period, preemption_next_check): Remove.
2745 (Vredisplay_preemption_period): Likewise.
2746 (update_frame, update_single_window, update_window, update_frame_1):
2747 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2748 used, following the 2012-06-22 change.
2750 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2752 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2754 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2756 * font.c (num_fonts): Remove the leftover from old
2757 debugging code. Adjust comment style here and there.
2758 * insdel.c (insert_1): Remove.
2759 * lisp.h (insert_1): Remove prototype.
2760 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2762 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2764 * w32.c (max_filename_mbslen): New function.
2765 (normalize_filename, readdir): Use it to detect locales where ANSI
2766 encoding of file names uses a double-byte character set (DBCS).
2767 If a DBCS encoding is used, advance by characters using
2768 CharNextExA, instead of incrementing a 'char *' pointer.
2769 Use _mbslwr instead of _strlwr. (Bug#13515)
2771 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2772 request of memory reservation to 1.7GB. (Bug#13065)

2781 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2782 Avoid redundant calls to strlen.
2784 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2786 Drop async_visible and async_iconified fields of struct frame.
2787 This is possible because async input is gone; for details, see
2788 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2789 * frame.h (struct frame): Remove async_visible and async_iconified
2790 members, convert garbaged to unsigned bitfield. Adjust comments.
2791 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2792 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2793 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2794 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2795 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2797 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2798 properly. Likewise for obscured.
2800 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2803 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2805 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2807 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2808 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2810 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2812 * xdisp.c (message2, message2_nolog): Remove functions.
2813 (message3, message3_nolog): Extract nbytes and multibyteness directly
2814 from the string. Change all callers.
2815 (message3_nolog): Don't set message_enable_multibyte since set_message
2816 will reset it anyway.
2817 (message1, message1_nolog): Use message3.
2818 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2819 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2820 (set_message): Drop all but the second arg, which has to be a string.
2821 (set_message_1): Simplify now that we know that a1 is NULL and the
2822 second arg is a string.
2823 * frame.h (struct frame): Remove `message_buf' field.
2824 Use glyphs_initialized_p instead.
2825 (FRAME_MESSAGE_BUF): Remove macro.
2826 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2827 * lisp.h (message2, message2_nolog): Remove declarations.
2828 (message3, message3_nolog): Update declarations.
2829 * keyboard.c (read_char_minibuf_menu_text)
2830 (read_char_minibuf_menu_width): Remove vars.
2831 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2832 to correctly handle multibyte strings.
2833 * frame.c (delete_frame): Don't free message_buf any more.
2834 * editfns.c (message_text, message_length): Remove vars.
2835 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2836 * fileio.c (auto_save_error): Use message3 instead of message2.
2837 * dispnew.c (adjust_frame_message_buffer): Remove function.
2839 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2841 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2842 real estate used for the tool bar and the menu bar.
2844 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2846 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2847 hidden buffer is prepared to modification (Bug#13164).
2849 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2851 * window.h (struct window): Change window_end_valid member from
2852 Lisp_Object to a bitfield. Adjust comments.
2853 (wset_window_end_valid): Remove.
2854 * window.c (adjust_window_count): Clear window_end_valid.
2855 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2856 (Fwindow_line_height, set_window_buffer, Frecenter)
2857 (Fsplit_window_internal, Fdelete_other_windows_internal)
2858 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2859 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2860 * xdisp.c (check_window_end, reconsider_clip_changes)
2861 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2862 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2863 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2865 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2867 * xdisp.c (mark_window_display_accurate): Simplify the loop
2868 assuming that the only one of vchild, hchild or buffer window
2869 slots is non-nil. Call mark_window_display_accurate_1 for
2870 the leaf windows only.
2871 (mark_window_display_accurate_1): Always assume leaf window.
2874 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2876 * emacs.c (Qkill_emacs_hook): Now static.
2878 * fileio.c (Finsert_file_contents): Simplify.
2879 Remove unnecessary assignments and tests.
2881 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2883 * w32.c (acl_set_file): Don't test for errors unless
2884 set_file_security returns FALSE. Avoids spurious errors when
2887 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2889 * fileio.c (Finsert_file_contents): Revert code introduced at
2890 2013-01-18 in favor of the simpler and generally better fix.
2891 Save stack space by removing 'buffer' and reusing 'read_buf'
2894 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2896 * lisp.h (eabs): Define unconditionally (Bug#13419).
2897 The old "#if !defined (eabs)" was an unnecessary revenant of back
2898 when this macro was called "abs". Document 'eabs' better.
2900 2013-01-19 Glenn Morris <rgm@gnu.org>
2902 * fns.c (Frandom): Doc fix.
2904 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2906 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2907 segfault when there are lots of overlays.
2909 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2910 when there are lots of overlays.
2911 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2912 for the details and a way to reproduce.
2914 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2916 * fileio.c: Use O_APPEND to append.
2917 This corresponds better to the natural interpretation of "append",
2918 and avoids the need to open the output file twice, or to invoke
2919 lseek when APPEND is neither nil nor a number.
2920 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2921 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2922 file possibly twice, and lseeking to its end; this avoids the
2923 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2924 at the same time: the combination is never needed and apparently
2925 it doesn't work with DOS_NT.
2927 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2928 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2930 Allow floating-point file offsets.
2931 Problem reported by Vitalie Spinu in
2932 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2933 * fileio.c (emacs_lseek): Remove.
2934 (file_offset): New function.
2935 (Finsert_file_contents, Fwrite_region): Use it.
2937 2013-01-19 Chong Yidong <cyd@gnu.org>
2939 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2940 aborting on Fsignal (Bug#13289).
2942 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2944 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2945 set_file_security as failure due to insufficient privileges.
2946 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2947 (fstat): Return owner and group like 'stat' and 'lstat' do.
2949 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2951 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2952 The bug was observed on Ubuntu operating inside a virtual machine,
2953 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2954 The workaround introduces a race condition on non-buggy hosts,
2955 but it's an unlikely race and anyway there's a nearly identical
2956 nearby race that can't be fixed.
2957 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2959 (Fwrite_region): Test for file system time stamp bug.
2960 (init_fileio): New function.
2961 * lisp.h (init_fileio): Declare it.
2962 * emacs.c (main): Call it.
2964 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2965 and make it more consistent with other stat-failure diagnostics.
2967 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2969 Fix crash when inserting data from non-regular files.
2970 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2971 for the error description produced by valgrind.
2972 * fileio.c (read_non_regular): Rename to read_contents.
2973 Free Lisp_Save_Value object used to pass parameters.
2974 (read_non_regular_quit): Rename to read_contents_quit.
2975 (Finsert_file_contents): Redesign internal file reading loop to adjust
2976 gap and end positions after each read and so help make_gap to work
2977 properly. Do not signal an I/O error too early and so do not leave
2978 not yet decoded characters in a buffer, which was the reason of
2979 redisplay crash. Use list2 to build return value. Adjust comments.
2981 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2983 Close a race when statting and reading files (Bug#13149).
2984 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2985 This avoids a race if the file is renamed between stat and open.
2986 This race is not the problem originally noted in Bug#13149;
2987 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2989 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2996 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2997 * alloc.c (format_save_value): Rename to make_save_value.
2998 (make_save_pointer): New function.
2999 (record_xmalloc): Use make_save_pointer.
3000 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
3001 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
3002 Change users of make_save_value to make_save_pointer.
3003 Likewise for format_save_value and make_save_value.

3016 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
3018 * keymap.c (map_keymap_internal): Use format_save_value.
3019 (map_keymap_char_table_item): Adjust accordingly.
3020 * fileio.c (non_regular_fd, non_regular_inserted)
3021 (non_regular_nbytes): Remove.
3022 (Finsert_file_contents): Convert trytry to ptrdiff_t.
3023 Use format_save_value to pass parameters to read_non_regular.
3024 (read_non_regular): Use XSAVE_ macros to extract parameters.
3026 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
3028 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
3030 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
3032 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
3033 extraction from any Lisp_Save_Value slot. Add type checking.
3034 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
3035 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
3036 * xselect.c: All users changed.
3038 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

3048 * editfns.c (save_excursion_save): Use format_save_value.
3049 (save_excursion_restore): Use XSAVE_OBJECT.
3051 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
3053 Avoid needless casts with XSAVE_POINTER.
3054 * alloc.c (mark_object) [GC_MARK_STACK]:
3055 * dired.c (directory_files_internal_unwind):
3056 * fileio.c (do_auto_save_unwind):
3057 * gtkutil.c (pop_down_dialog):
3058 * keymap.c (map_keymap_char_table_item):
3059 * lread.c (load_unwind):
3060 * nsmenu.m (pop_down_menu):
3061 * print.c (print_object) [GC_MARK_STACK]:
3062 * xfns.c (clean_up_file_dialog):
3063 * xmenu.c (cleanup_widget_value_tree):
3064 Omit casts between XSAVE_POINTER and a pointer type.
3066 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
3068 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
3069 * eval.c (eval_sub): Protect `form' from being GCed before its
3070 car and cdr becomes protected with the backtrace entry.
3072 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
3074 Make Lisp_Save_Value more versatile storage for up to four objects.
3075 * lisp.h (toplevel): Enumeration to describe types of saved objects.
3076 (struct Lisp_Save_Value): New layout. Adjust comments.
3077 (XSAVE_POINTER): New macro.
3078 (XSAVE_INTEGER): Likewise.
3079 (allocate_misc): Add prototype.
3080 (free_misc): Likewise.
3081 * alloc.c (allocate_misc): Now global.
3082 (free_misc): Likewise. Adjust comment.
3083 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
3084 (free_save_value): Likewise.
3085 (mark_object): Likewise.
3086 * editfns.c (save_excursion_save): Pack everything within
3087 Lisp_Save_Value and so avoid xmalloc.
3088 (save_excursion_restore): Adjust to match new layout. Use free_misc
3089 because we do not allocate extra memory any more. Add eassert.
3090 * print.c (print_object): New code to print Lisp_Save_Value. Do not
3091 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
3092 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
3093 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

3099 (nsfont_draw): Remove disabling of LCD smoothing.
3100 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
3101 Bug#11484 with LCD smoothing on.
3103 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
3105 Fix SIGDANGER handlers, for AIX (Bug#13408).
3106 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
3107 Move handlers here from emacs.c; they were out of place.

3111 * xterm.c (syms_of_xterm): Adjust documentation for
3112 scroll-bar-adjust-thumb-portion.
3114 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)

3118 Use variable for MOTIF.
3120 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for GTK.
3122 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

3126 (doCommandBySelector:): Set processingCompose to NO.
3128 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
3129 Remove check for fkeys count > zero, block/unblock fixes the real bug.
3130 (nsfont_list_family): Add block/unblock_input calls.
3131 (nsfont_open): Move block_input earlier. Add unblock_input before early
3133 (nsfont_draw): Add block/unblock_input calls.
3135 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
3137 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
3138 for old_charpos and old_bytepos.
3140 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
3142 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
3143 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
3144 Clear tzvalbuf_in_environ if this workaround is in effect.
3145 Problem and fix reported by Kazuhiro Ito.
3147 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
3149 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):

3156 string cross-reference(s).
3158 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
3160 Avoid unnecessary byte position calculation for the gap movement.
3161 Since all users of move_gap do CHAR_TO_BYTE for other purposes
3162 anyway, all of them should use move_gap_both instead.
3163 * lisp.h (move_gap): Remove prototype.
3164 * insdel.c (move_gap): Remove.
3165 (move_gap_both): Add eassert.
3166 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

3172 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
3174 * term.c (init_tty): Use them instead of rolling our own code.
3175 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
3176 switches from 'signal' to 'pthread_sigmask', which is safer in
3177 multithreaded applications.
3178 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
3179 which has already arranged for that.
3180 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
3181 This is the main part of the bug fix.
3183 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
3185 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around
3186 x_last_font_name (Bug#13403).
3188 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
3190 Omit buffer_slot_type_mismatch and use generic predicates to enforce
3191 the type of per-buffer values where appropriate.
3192 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
3193 predicate, which is how it's really used now. Adjust comment.
3194 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
3195 * buffer.c (buffer_slot_type_mismatch): Remove.
3196 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

3200 left-margin-width, right-margin-width, left-fringe-width,
3201 right-fringe-width, scroll-bar-width and buffer-display-count.
3202 Use Qstringp for default-directory, buffer-file-name,
3203 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
3204 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
3206 * data.c (store_symval_forwarding): Adjust to call the predicate.
3208 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
3210 * w32.c (get_name_and_id, acl_set_file):
3211 * w32term.c (w32fullscreen_hook): Remove unused local variables.
3213 2013-01-09 Dmitry Antipov <dmantipov@yandex.ru>
3215 * lisp.h (make_gap_1): New prototype.
3216 * buffer.h (GAP_BYTES_DFL, GAP_BYTES_MIN): New macros for the special

3220 (syms_of_editfns): Adjust defsubr. Drop commented-out obsolete code.
3221 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
3222 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
3223 (make_gap_1): New function to adjust the gap of any buffer.
3224 * coding.c (coding_alloc_by_making_gap): Use it.
3225 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
3226 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
3228 2013-01-08 Juri Linkov <juri@jurta.org>
3230 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
3231 of (supports :underline (:style wave)). (Bug#13000)
3233 2013-01-08 Aaron S. Hawley <aaron.s.hawley@gmail.com>
3235 * undo.c (Fprimitive_undo): Move to simple.el.

3240 * keyboard.c (echo_add_key): Rename from echo_add_char.
3242 2013-01-06 Chong Yidong <cyd@gnu.org>
3244 * keyboard.c (echo_add_char): New function, factored out from
3245 echo_char. Don't add a space if the previous echo string was
3247 (echo_char): Use it.
3248 (read_key_sequence): When echoing mock input, ensure that the
3249 trailing dash is properly added.
3251 2013-01-05 Eli Zaretskii <eliz@gnu.org>
3253 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
3254 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
3255 digits for buffer positions, before misalignment starts.
3256 Display "0" for integer "object" field.
3257 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
3258 Display the newline glyph more unambiguously.
3260 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3262 * nsterm.m (ns_draw_underwave):
3263 * w32term.c (w32_draw_underwave):
3264 * xterm.c (x_draw_underwave): Make underwave look more triangular
3265 and also degrade gracefully for small fonts. (Bug#13000)
3267 * nsterm.m (ns_draw_text_decoration):
3268 * w32term.c (x_draw_glyph_string):
3269 * xterm.c (x_draw_glyph_string): Don't use previous underline
3270 thickness and position if previous underline type is underwave.
3272 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
3274 * fileio.c (Ffile_acl): Undocument return format.
3276 2013-01-02 Glenn Morris <rgm@gnu.org>
3278 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
3280 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>

3287 * fringe.c (compute_fringe_widths):
3288 * lread.c (read_list):
3289 * minibuf.c (Ftry_completion):
3290 * term.c (tty_ins_del_lines):
3291 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
3292 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
3294 2012-12-31 Eli Zaretskii <eliz@gnu.org>
3296 * w32.c (unsetenv): Set up the string passed to _putenv
3298 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
3299 for the bug this caused.
3301 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
3303 * coding.c (Qmac): Now static.
3305 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
3307 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
3308 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
3309 handlebox_widget. Set toolbar_in_hbox to false/true, set
3310 toolbar_is_packed to true.
3311 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
3312 (update_frame_tool_bar): Check toolbar_is_packed for packing.
3313 Show all on TOOLBAR_TOP_WIDGET.
3314 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
3315 by TOOLBAR_TOP_WIDGET.
3316 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
3317 Check toolbar_is_packed.
3318 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
3319 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3320 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
3322 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3323 (xg_update_menubar): Update title only if
3324 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3325 (xg_update_submenu): Skip tearoff only if
3326 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3327 (xg_initialize): Initialize xg_detached_menus only if
3328 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3330 * xterm.h (struct x_output): Surround handlebox_widget with
3331 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
3332 toolbar_in_hbox is bool.
3334 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
3336 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
3337 (LIBS_GNUSTEP): Define.
3338 (LIBES): Add $(LIBS_GNUSTEP).
3339 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
3341 2012-12-30 Eli Zaretskii <eliz@gnu.org>
3343 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
3344 continuation glyph on a TTY with an indication of an empty line.
3347 2012-12-29 Eli Zaretskii <eliz@gnu.org>
3349 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
3350 file's SELinux context or ACLs successfully set, nil otherwise.
3352 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
3354 * w32proc.c (reader_thread): Avoid passing NULL handles to
3355 SetEvent and WaitForSingleObject.
3357 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
3359 Port EXTERNALLY_VISIBLE to Clang 3.2.
3360 * conf_post.h (__has_attribute): New macro.
3361 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
3363 2012-12-27 Glenn Morris <rgm@gnu.org>
3365 * cygw32.c (Fcygwin_convert_file_name_to_windows)
3366 (Fcygwin_convert_file_name_from_windows): Doc fixes.
3368 2012-12-27 Eli Zaretskii <eliz@gnu.org>
3370 * fileio.c (file_name_as_directory, directory_file_name):
3371 Accept an additional argument MULTIBYTE to indicate whether the input C
3372 came from a multibyte or a unibyte Lisp string; all callers
3373 adjusted. Don't assume the input string is always multibyte.
3375 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
3376 don't ENCODE_FILE them, and return a unibyte string if the input
3378 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
3379 don't assume the input strings will always be multibyte. If the
3380 input strings are multibyte, decode strings obtained from C
3383 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3385 * lisp.h (toplevel): Add two notices to the comment about
3386 defining a new Lisp data type.

3390 * alloc.c (valid_lisp_object_p): Adjust comment.
3392 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3394 * keyboard.c (record_asynch_buffer_change): Initialize an event
3395 only if it's really needed.
3396 * frame.h (enum output_method): Remove output_mac member since
3397 it's a leftover from the deleted code.
3398 * frame.c (Fframep): Adjust user here ...
3399 * terminal.c (Fterminal_live_p): ... and here.
3400 * coding.c (Qmac): Now here because it's only used to denote
3401 end-of-line encoding type.
3402 (syms_of_coding): DEFSYM it.
3403 * frame.h (Qmac): Remove duplicated declaration.
3405 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
3407 * window.c (select_window_1): Now static, since it's used only here.
3409 2012-12-25 Eli Zaretskii <eliz@gnu.org>
3411 * window.c (window_body_cols): Subtract display margins from the
3412 window body width on TTYs as well. See
3413 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
3414 for the original report.
3416 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
3418 * xdisp.c (redisplay_window): Remove inner local variable
3419 because the outer shadowed one has the same meaning.
3420 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3422 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3423 (xg_create_tool_bar): Adjust users.
3425 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3427 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3428 * buffer.c (Fget_buffer_create): Use it to set compact field of
3429 struct buffer_text to avoid accessing an uninitialized value
3430 when compact_buffer is called for the first time.
3431 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3432 (Fset_buffer_modified_p): Use buffer_window_count to check
3433 whether the buffer is displayed in some window.
3434 * xdisp.c (message_dolog): Likewise.
3436 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3438 * w32.c (acl_set_file): If setting the file security descriptor
3439 fails, and the new DACL is identical to the existing one, silently
3440 return success. This fixes problems for users backing up their
3441 own files without having the necessary privileges for setting
3442 security descriptors.
3444 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3446 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3447 after WaitForSingleObject returns normally. This expedites reader
3448 thread shutdown when delete_child triggers it.
3449 (reap_subprocess): More accurate commentary for why we call
3450 delete_child only when cp->fd is negative.
3452 * w32.c (sys_close): Do not call delete_child on a subprocess
3453 whose handle is not yet closed. Instead, set its file descriptor
3454 to a negative value, so that reap_subprocess will call
3455 delete_child on that subprocess when its SIGCHLD arrives.
3456 This avoids closing handles used for communications between sys_select
3457 and reader_thread, which doesn't give sys_select a chance to
3458 notice that the process exited and invoke the SIGCHLD handler for
3461 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3463 * nsfns.m (Fns_do_applescript): Run event loop until script has
3464 been executed (Bug#12969).
3465 (ns_run_ascript): Chech as_script for nil, set to nil after
3468 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3470 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3472 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3474 * w32term.c (w32fullscreen_hook): New function.
3475 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3477 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3479 * fileio.c (Finsert_file_contents): Doc fix.
3481 * w32proc.c (new_child, delete_child, find_child_pid): For a
3482 subprocess, consider its slot being in use as long as its process
3483 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3484 slot when a new process is started immediately after killing
3485 another one, without waiting enough time for the first process to
3486 be reaped and resources allocated for it be orderly freed.
3488 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3490 2012-12-21 Chong Yidong <cyd@gnu.org>
3492 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3494 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3496 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3498 * w32.c (get_name_and_id): Always pass NULL as the first argument
3499 of lookup_account_sid. Avoids crashes with UNC file names that
3500 refer to DFS domains, not to specific machine names. (Bug#12621)
3501 Remove now unused argument FNAME; all callers changed.
3502 (get_file_owner_and_group): Remove now unused argument FNAME; all
3505 2012-12-21 Chong Yidong <cyd@gnu.org>
3507 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3508 error for invalid chars, don't check for a nil return value.
3510 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3512 Avoid calls to CHAR_TO_BYTE if byte position is known.
3513 * editfns.c (make_buffer_string_both): Use move_gap_both.
3514 (Fbuffer_string): Use make_buffer_string_both.
3515 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3517 (buf_bytepos_to_charpos): Likewise.
3518 (charpos_to_bytepos): Remove.
3519 * fileio.c (Finsert_file_contents): Use move_gap_both.
3520 * search.c (Freplace_match): Likewise.
3521 * process.c (process_send_region): Likewise. Use convenient
3522 names for byte positions.
3523 * lisp.h (charpos_to_bytepos): Remove prototype.
3524 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3525 * insdel.c (move_gap): Likewise.
3527 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3529 * xdisp.c (redisplay_internal): Remove now-unused local.
3531 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3533 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3534 (redisplay_internal): Don't bother selecting the frame to get the
3535 proper value of frame-local variables (bug#13225).
3537 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3539 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3540 Rename 4th argument since it may be buffer or string. Adjust comment.
3541 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3543 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3545 * coding.c (Fdetect_coding_region): Do not check start and end with
3546 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3547 (code_convert_region): Likewise.
3549 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3551 * w32.c (acl_get_file, acl_set_file): Run the file name through
3552 map_w32_filename, and resolve any symlinks in the file name, like
3554 (acl_set_file): Call revert_to_self, if any privileges were
3557 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3559 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3560 ($(BLD)/w32.$(O)): Update dependencies.
3562 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3564 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3565 propagate redisplay's scrolling (if any) to the right window.
3566 (redisplay_internal): Use ensure_selected_frame.
3567 (display_mode_lines): Complete last fix.
3568 * window.c (select_window_1): New func, extracted from select_window.
3569 (select_window): Use it.
3570 * window.h (select_window_1): Declare.
3572 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3574 Emulate Posix ACL APIs on MS-Windows.
3575 * w32.c: Include sddl.h and sys/acl.h.
3576 (SDDL_REVISION_1): Define if not already defined.
3577 (g_b_init_get_security_descriptor_dacl)
3578 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3579 (g_b_init_is_valid_security_descriptor)
3580 (g_b_init_set_file_security): New static flags.

3592 (acl_free, acl_get_file, acl_set_file): New functions.
3594 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3596 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3598 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3599 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3600 for some of that bug's symptoms can now cause Emacs to abort.
3601 Remove the workaround.
3602 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3603 The bug that caused SIGCHLD to get lost has been fixed, and the
3604 workaround for it can now cause Emacs to abort.
3606 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3608 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3609 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3610 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3612 2012-12-16 Romain Francoise <romain@orebokech.com>
3614 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3615 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3616 and copy ACL entries of file in addition to SELinux context if set.
3617 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3619 * Makefile.in (LIBACL_LIBS): New macro.
3622 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3624 * fileio.c (internal_delete_file): Use bool for boolean.
3626 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3628 Fix bug #13079 on MS-Windows with temp files not being deleted.

3631 (register_child): First argument is now pid_t.
3632 (record_infile, record_pending_deletion): New prototypes.
3634 * w32proc.c (new_child): Initialize input_file and
3635 pending_deletion members of the child.
3636 (delete_child): Delete the child's temporary input file, if any,
3637 that is pending deletion.
3638 (register_child): First argument is now pid_t.
3639 (record_infile, record_pending_deletion): New functions.
3640 (reap_subprocess): Fix a typo in DebPrint string.
3641 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3643 * fileio.c (internal_delete_file): Return an int again: non-zero
3644 if delete-file succeeds, zero otherwise.
3646 * lisp.h (internal_delete_file): Adjust prototype.
3648 * callproc.c (Fcall_process): Don't overwrite infile with result
3650 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3651 asynchronous subprocess, record the name of the input file name,
3653 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3654 delete the file, record it as pending deletion when the subprocess
3657 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3659 * editfns.c [HAVE_PWD_H]: Include grp.h.
3661 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3663 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3665 Fix permissions bugs with setgid directories etc. (Bug#13125)
3666 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3667 to mark it as a placeholder. The old value was often wrong.
3668 The only user of this attribute has been changed to use
3669 file-ownership-preserved-p instead, with its new group arg.
3670 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3672 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
3674 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

3677 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3679 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3680 try to get accurate owner and group information from NT file
3681 security APIs. This is to make most callers of 'stat' and
3682 'lstat', which don't need that information, much faster.
3684 * dired.c (Ffile_attributes) [WINDOWSNT]:
3685 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3686 owner and group information from 'lstat'.
3688 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3690 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3691 as that confuses set-auto-coding, so insist on the head-read
3692 returning the full 1024 bytes. Let lseek compute the tail offset;
3693 less work for us. Do not ignore I/O errors when reading the tail.
3695 * xdisp.c: Minor style fixes.
3696 (init_iterator): Hoist assignment out of if-expression.
3697 (markpos_of_region): Callers now test for sign, not for -1.
3699 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3701 Minor redisplay optimization when the region length is zero.
3702 * xdisp.c (markpos_of_region): New function.
3703 (init_iterator): Do not highlight the region of zero length.
3704 (redisplay_window): Check whether the region is of non-zero length.
3705 (try_cursor_movement): Allow if the region length is zero.
3706 (try_window_reusing_current_matrix, try_window_id): Likewise.
3708 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3710 * search.c (search_buffer): Check the inverse translations of each
3711 character in pattern when the buffer being searched is unibyte.
3714 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>

3723 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3724 Remove unnecessary S_ISLNK test, as (contra the comments) this
3725 function can't copy symlinks. Improve quality of error message
3726 when attempting to copy files that are neither regular files nor

3959 * dbusbind.c (Fdbus_init_bus):
3961 * xterm.c (x_term_init):

3972 no longer needed here.
3973 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:

3975 (set_time_zone_rule): Maintain the TZ=value string separately.
3976 (syms_of_editfns): Don't initialize initial_tz;
3977 init_editfns now does it.

3998 Remove USG and vlimit methods; no longer used these days.
3999 Add #error catchall just in case.
4001 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
4002 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,

4028 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
4030 * frame.c (make_frame): Do not set window's buffer to t.
4031 * window.c (Fsplit_window_internal): Likewise. Previously it was
4032 used to indicate that the window is being set up. Now we use
4033 set_window_buffer for all new windows, so the condition in ...
4034 (Fset_window_buffer): ... is always true and can be removed.
4036 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
4038 Convenient macro to check whether the buffer is hidden.
4039 * buffer.h (BUFFER_HIDDEN_P): New macro.

4065 Fix a recently-introduced delete-process race condition.
4066 * callproc.c, process.h (record_kill_process):
4067 New function, containing part of the old call_process_kill.
4068 (call_process_kill): Use it.
4069 This does not change call_process_kill's behavior.
4070 * process.c (Fdelete_process): Use record_kill_process to fix a
4071 race condition that could cause Emacs to lose track of a child.
4073 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
4075 Avoid code duplication between prev_frame and next_frame.
4076 * frame.c (candidate_frame): New function. Add comment.

4079 2012-12-06 Eli Zaretskii <eliz@gnu.org>
4081 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
4082 fails, signal an error instead of continuing with an empty
4084 Encode expanded temp file pattern before passing it to mkstemp or
4087 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
4088 Encode the file name before passing it to dostounix_filename, in
4089 case it will downcase it (under w32-downcase-file-names).
4092 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
4094 Minor call-process cleanups.
4095 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
4096 at the same time as other platforms, to simplify analysis.
4097 No need for fd0_volatile since we have synch_process_fd.
4098 Avoid needless emacs_close; arg is always negative.
4100 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
4102 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

4107 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
4108 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
4109 and mouse_face_hidden members to a bitfields.

4114 member. Adjust users. Convert term_initted, delete_in_insert_mode,
4115 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
4116 members to a bitfields.
4118 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
4120 Don't let call-process be a zombie factory (Bug#12980).
4121 Fixing this bug required some cleanup of the signal-handling code.
4122 As a side effect, this change also fixes a longstanding rare race
4123 condition whereby Emacs could mistakenly kill unrelated processes,
4124 and it fixes a bug where a second C-g does not kill a recalcitrant
4125 synchronous process in GNU/Linux and similar platforms.
4126 The patch should also fix the last vestiges of Bug#9488,
4127 a bug which has mostly been fixed on the trunk by other changes.
4128 * callproc.c, process.h (synch_process_alive, synch_process_death)
4129 (synch_process_termsig, sync_process_retcode):
4130 Remove. All uses removed, to simplify analysis and so that
4131 less consing is done inside critical sections.
4132 * callproc.c (call_process_exited): Remove. All uses replaced
4133 with !synch_process_pid.
4134 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
4135 These take the role of what used to be in unwind-protect arg.
4137 (block_child_signal, unblock_child_signal):
4138 New functions, to avoid races that could kill innocent-victim processes.
4139 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
4140 (call_process_kill): Record killed processes as deleted, so that
4141 zombies do not clutter up the system. Do this inside a critical
4142 section, to avoid a race that would allow the clutter.
4143 (call_process_cleanup): Fix code so that the second C-g works again
4144 on common platforms such as GNU/Linux.
4145 (Fcall_process): Create the child process in a critical section,
4146 to fix a race condition. If creating an asynchronous process,
4147 record it as deleted so that zombies do not clutter up the system.
4148 Do unwind-protect for WINDOWSNT too, as that's simpler in the
4149 light of these changes. Omit unnecessary call to emacs_close
4150 before failure, as the unwind-protect code does that.
4151 * callproc.c (call_process_cleanup):
4152 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
4153 * process.c (record_deleted_pid): New function, containing
4154 code refactored out of Fdelete_process.
4155 (Fdelete_process): Use it.
4156 (process_status_retrieved): Remove. All callers changed to use
4157 child_status_change.
4158 (record_child_status_change): Remove, folding its contents into ...
4159 (handle_child_signal): ... this signal handler. Now, this
4160 function is purely a handler for SIGCHLD, and is not called after
4161 a synchronous waitpid returns; the synchronous code is moved to
4162 wait_for_termination. There is no need to worry about reaping
4163 more than one child now.
4164 * sysdep.c (get_child_status, child_status_changed): New functions.
4165 (wait_for_termination): Now takes int * status and bool
4166 interruptible arguments, too. Do not record child status change;
4167 that's now the caller's responsibility. All callers changed.
4168 Reimplement in terms of get_child_status.
4169 (wait_for_termination_1, interruptible_wait_for_termination):
4170 Remove. All callers changed to use wait_for_termination.
4171 * syswait.h: Include <stdbool.h>, for bool.
4172 (record_child_status_change, interruptible_wait_for_termination):
4174 (record_deleted_pid, child_status_changed): New decls.
4175 (wait_for_termination): Adjust to API changes noted above.
4177 * bytecode.c, lisp.h (Qbytecode): Remove.

4234 Fix xpalloc confusion after memory is exhausted.
4235 * alloc.c (xpalloc): Comment fix.
4236 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory

4281 * callproc.c (Fcall_process): Fix vfork portability problems.
4282 Do not assume that fd[0], count, filefd, and save_environ survive
4283 vfork. Fix bug whereby wrong errno value could be reported for
4284 pipe failure. Some minor cleanups, too, as follows. Move buf and
4285 bufsize to the context where they're needed. Change new_argv to
4286 be of type char **, as this is more convenient and avoids casts.
4287 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4288 Now local constants, not macros.
4290 2012-11-18 Kenichi Handa <handa@gnu.org>

4340 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4341 between bpos_covered and bpos_max. This fixes cursor display when
4342 several display strings follow each other.
4344 * .gdbinit (pgx): If the glyph's object is a string, display the
4345 pointer to string data, rather than the value of the string object
4346 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4348 * indent.c (Fvertical_motion): If the starting position is covered
4349 by a display string, return to one position before that, to avoid
4350 overshooting it inside move_it_to. (Bug#12930)
4352 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

4364 * xterm.h (struct x_output): Drop outdated #if 0 code.
4365 Use bitfields for explicit_parent, asked_for_visible,
4366 has_been_visible and net_wm_state_hidden_seen members.

4377 * dired.c: Assume HAVE_DIRENT_H.
4378 (NAMLEN): Remove, replacing with ...
4379 (dirent_namelen): New function. All uses changed. Use the GNU macro
4380 _D_EXACT_NAMELEN if available, as it's faster than strlen.
4381 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
4382 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
4383 * makefile.w32-in (DIR_H): Remove. All uses replaced with

4393 * xftfont.c (xftfont_open): Remove duplicate assignment.
4395 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4397 * alloc.c (Fgarbage_collect): Unblock input after clearing

4399 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4400 * msdos.c (IT_frame_up_to_date): Use it here...
4401 * w32term.c (w32_frame_up_to_date): ...here...
4402 * xterm.c (XTframe_up_to_date): ...and here...
4403 * nsterm.m (ns_frame_up_to_date): ...but not here.

4445 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4447 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4448 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4449 Define for the MSVC compiler.
4451 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

4496 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4497 cygwin_convert_file_name*.
4499 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):

4506 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4508 * w32select.c: Include w32common.h before w32term.h, so that
4509 windows.h gets included before w32term.h uses some of its
4510 features, see below.

4514 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

4542 * emacs.c, term.c (O_RDWR): Remove.
4543 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than

4545 * nsterm.m: Assume <fcntl.h> exists.
4546 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4547 (create_pty, Fmake_network_process, server_accept_connection)
4548 (wait_reading_process_output, init_process_emacs):
4550 (wait_reading_process_output): Put in a special case for WINDOWSNT
4551 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4552 It's not clear this is needed, but it's a more-conservative change.
4553 (create_process): Assume FD_CLOEXEC.
4554 (create_process, create_pty): Assume O_NOCTTY.
4555 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4556 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4557 Omit if not DOS_NT, since F_GETFL is not defined there.
4558 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4559 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4561 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4562 lack it, since gnulib guarantees this.

4565 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4567 * w32.c (faccessat): Pretend that directories have the execute bit
4568 set. Emacs expects that, e.g., in files.el:cd-absolute.
4570 * w32proc.c (create_child): Don't clip the PID of the child
4571 process to fit into an Emacs integer, as this is no longer a
4573 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4574 reaping only the process specified by PID argument, if that is
4575 positive. Use PID instead of dead_child to know which process to
4576 reap. Wait for the child to die only if WNOHANG is not in
4578 (sys_select): Don't set dead_child.
4580 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4581 as it is no longer needed.
4583 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,

4590 Fix problems in ns port found by static checking.
4591 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4592 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4593 not to process group.
4594 (ns_select): Use emacs_write, not write, as that's more robust
4595 in the presence of signals.
4596 (fd_handler:): Check for read errors.
4598 2012-11-16 Glenn Morris <rgm@gnu.org>
4600 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

4608 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4609 use the same value of thread handle.
4610 (start_timer_thread): If the timer thread exited (due to error),
4611 clean up by closing the two handles it used. Duplicate the caller
4612 thread's handle here, so it gets duplicated only once, when
4613 launching the timer thread. Set priority of the timer thread, not
4615 (getitimer): Don't duplicate the caller thread's handle here.
4618 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4620 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4623 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4625 Remove no-longer-used pty_max_bytes variable.
4626 * process.c (pty_max_bytes): Remove; unused.
4627 (send_process): Do not set it.
4629 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4631 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4632 Update dependencies.
4634 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4636 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4637 This follows up on the 2012-09-29 patch that removed indirection
4638 for the 'function' field. Reported by Sergey Vinokurov in
4639 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4641 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4643 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4644 different name, as the MS runtime does not have such a function,
4645 and probably never will.) All callers changed. Ignore DIRFD
4646 value if PATH is an absolute file name, to match Posix spec
4647 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4650 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4652 * xdisp.c (echo_area_display, redisplay_internal):
4653 Omit redundant check whether frame_garbaged is set.
4655 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4657 Use faccessat, not access, when checking file permissions (Bug#12632).
4658 This fixes a bug that has been present in Emacs since its creation.
4659 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4660 which must set some sort of record. (Torek's bug report was against
4661 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4662 same common flaw.) See Torek's Usenet posting
4663 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4664 Posted: Fri Apr 8 14:18:56 1983.
4665 * Makefile.in (LIB_EACCESS): New macro.
4667 * callproc.c (init_callproc):
4668 * charset.c (init_charset):
4669 * fileio.c (check_existing, check_executable, check_writable)
4671 * lread.c (openp, load_path_check):
4672 * process.c (allocate_pty):
4674 Use effective UID when checking permissions, not real UID.
4675 * callproc.c (init_callproc):
4676 * charset.c (init_charset):
4677 * lread.c (load_path_check, init_lread):
4678 Test whether directories are accessible, not merely whether they exist.
4679 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4680 * fileio.c (check_existing, check_executable, check_writable)
4682 Use symbolic names instead of integers for the flags, as they're
4684 (check_writable): New arg AMODE. All uses changed.
4685 Set errno on failure.
4686 (Ffile_readable_p): Use faccessat, not stat + open + close.
4687 (Ffile_writable_p): No need to call check_existing + check_writable.
4688 Just call check_writable and then look at errno. This saves a syscall.
4689 dir should never be nil; replace an unnecessary runtime check
4690 with an eassert. When checking the parent directory of a nonexistent
4691 file, check that the directory is searchable as well as writable, as
4692 we can't create files in unsearchable directories.
4693 (file_directory_p): New function, which uses 'stat' on most platforms
4694 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4695 (Ffile_directory_p, Fset_file_times): Use it.
4696 (file_accessible_directory_p): New function, which uses a single
4697 syscall for efficiency.
4698 (Ffile_accessible_directory_p): Use it.
4699 * xrdb.c (file_p): Use file_directory_p.
4700 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4701 * lread.c (openp): When opening a file, use fstat rather than
4702 stat, as that avoids a permissions race. When not opening a file,
4703 use file_directory_p rather than stat.
4704 (dir_warning): First arg is now a usage string, not a format.
4705 Use errno. All uses changed.
4706 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4707 that merely introduced a race.
4708 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4709 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4710 and similarly for the other O_* flags.
4711 * w32.c (sys_faccessat): Rename from sys_access and switch to
4712 faccessat's API. All uses changed.
4713 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4714 (magic_db): Rename from magic_file_p.
4715 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4716 char *, so that we don't have to test for file existence
4717 separately from opening the file for reading. This removes a race
4718 fixes a permission-checking problem, and simplifies the code.
4720 (file_p): Remove; no longer needed.
4722 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4724 Omit glyphs initialization at startup.
4725 * dispnew.c (glyphs_initialized_initially_p): Remove.
4726 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4727 (Fredraw_frame): Move actual code from here...
4728 (redraw_frame): ...to here. Add eassert. Adjust comment.
4729 (Fredraw_display): Use redraw_frame.
4730 * xdisp.c (clear_garbaged_frames): Likewise.
4732 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4734 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4735 passed to pint2str and pint2hrstr to be at most the size of the
4736 frame's decode_mode_spec_buffer. This avoids crashes with very
4737 large values of FIELD_WIDTH argument to decode_mode_spec.
4740 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4742 Fix a race with verify-visited-file-modtime (Bug#12863).
4743 Since at least 1991 Emacs has ignored an mtime difference of no
4744 more than one second, but my guess is that this was to work around
4745 file system bugs that were fixed long ago. Since the race is
4746 causing problems now, let's remove that code.
4747 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4748 whose time stamp is off by no more than a second. Insist that the
4749 file time stamps match exactly.
4751 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4753 * frame.h (struct frame): Convert external_tool_bar member to
4754 1-bit unsigned bitfield.
4755 * termhooks.h (struct terminal): Remove mouse_moved member since
4756 all users are long dead. Adjust comment on mouse_position_hook.
4758 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4760 Simplify by using FOR_EACH_FRAME here and there.
4761 * frame.c (next_frame, prev_frame, other_visible_frames)
4762 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4763 * w32term.c (x_window_to_scroll_bar): Likewise.
4764 * window.c (window_list): Likewise.
4765 * xdisp.c (x_consider_frame_title): Likewise.
4766 * xfaces.c (Fdisplay_supports_face_attributes_p): Likewise.
4767 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4768 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4769 * xmenu.c (menubar_id_to_frame): Likewise.
4770 * xselect.c (frame_for_x_selection): Likewise.
4771 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4772 (x_window_to_menu_bar): Likewise.
4773 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4775 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4777 * data.c (Qdefalias_fset_function): Now static.
4779 Another tweak to vectorlike_header change.
4780 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4781 Remove, and replace all uses with ...
4782 (next_in_free_list, set_next_in_free_list):
4783 New functions, which respect C's aliasing rules better.
4785 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4787 * window.c (list4i): Rename from 'quad'. All uses changed.
4788 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4790 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4792 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4793 warning about mixing declarations and code in ISO C90.
4795 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4797 * window.c (Fsplit_window_internal): Set combination limit of
4798 new parent window to t iff Vwindow_combination_limit is t;
4799 fixing a regression introduced with the change from 2012-09-22.
4800 (Fset_window_combination_limit): Fix doc-string.
4802 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4804 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4805 amount when the scroll margins are too large. When scrolling
4806 backwards in the buffer, give up if cannot reach point or the
4807 scroll margin within a reasonable number of screen lines.
4808 Fixes point position in window under scroll-up/down-aggressively when
4809 point is positioned many lines beyond the window top/bottom.
4812 * ralloc.c (relinquish): If real_morecore fails to return memory
4813 to the system, don't crash; instead, leave the last heap
4814 unchanged and return. (Bug#12774)
4816 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4818 * lisp.h (AUTOLOADP): New macro.
4819 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4820 * data.c (Ffset): Remove special ad-advice-info handling.
4821 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4823 (Finteractive_form): Simplify.
4824 (Fquo): Don't insist on having at least 2 arguments.
4825 (Qdefalias_fset_function): New var.
4827 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4829 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4831 * nsfont.m (Qcondensed, Qexpanded): New variables.
4832 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4833 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4835 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4837 Fix recently introduced crash on MS-Windows (Bug#12839).
4838 * w32term.h (struct scroll_bar): Use convenient header.
4839 (SCROLL_BAR_VEC_SIZE): Remove.
4840 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4842 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4844 Tweak last vectorlike_header change.
4845 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4846 vectorlike object on the free list. This is introduced to avoid
4847 some (but not all) pointer casting and aliasing problems, see
4848 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4849 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4851 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4853 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4855 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4856 been removed, so remove them here also.
4858 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4860 * doc.c (Fdocumentation): Handle new property
4861 dynamic-docstring-function to replace the old ad-advice-info.
4863 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4865 * fns.c (Qeql, hashtest_eq): Now static.
4867 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4869 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4870 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4871 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4872 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4874 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4876 Use same hash function for hashfn_profiler as for hash_string etc.
4877 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4878 * lisp.h (sxhash_combine): New inline function, with the contents
4879 of the old SXHASH_COMBINE.
4880 * profiler.c (hashfn_profiler): Use it, instead of having a
4881 special hash function containing a comparison that always yields 1.
4883 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4885 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4886 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4887 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4890 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4892 * image.c (xpm_make_color_table_h): Fix compiler error because
4893 make_hash_table changed.
4895 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4897 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4899 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4901 Use ad-hoc comparison function for the profiler's hash-tables.
4902 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4903 (make_log): Use them.
4904 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4905 call Fequal any more.

4914 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4915 (hash_lookup, hash_remove_from_table): Move assertion checking of
4916 hashfn result here. Check hash-equality before calling cmpfn.

4926 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4928 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4929 value of w32-scroll-lock-modifier is neither nil nor one of the
4930 known key modifiers. (Bug#12806)
4932 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4934 Shrink struct vectorlike_header to the only size field.
4935 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4937 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4938 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4939 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4940 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4941 information from the vector header. Adjust comment.

4953 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4954 (Fmake_bool_vector): Likewise.
4955 (struct large_vector): New type to represent allocation unit for
4956 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4957 (large_vectors): Change type to struct large_vector.
4958 (allocate_vector_from_block): Simplify.
4959 (PSEUDOVECTOR_NBYTES): Replace with...
4960 (vector_nbytes): ...new function. Adjust users.
4961 (sweep_vectors): Adjust processing of large vectors.

4967 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4968 * buffer.h (struct buffer): Add next member.

4981 * keyboard.c (event_to_kboard): Do not dereference
4982 frame_or_window field of SELECTION_REQUEST_EVENT
4983 and SELECTION_CLEAR_EVENT events (Bug#12814).
4984 * xterm.h (struct selection_input_event): Adjust comment.
4986 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4988 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4989 such as Scroll Lock, if the respective keys are treated as
4990 function keys, not as modifiers. This avoids destroying non-ASCII
4991 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4993 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4995 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4997 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4999 Restore some duplicate definitions (Bug#12814).
5000 This undoes part of the 2012-11-03 changes. Some people build
5001 with plain -g rather than with -g3, and they need the duplicate
5002 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
5003 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
5004 Define as macros, as well as as enums or as constants.
5006 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
5008 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
5009 to keypad keys (Bug#12816).
5011 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
5013 Minor adjustments of recently-changed frame functions.
5014 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
5015 known to be a frame (we're in the FRAMEP branch).
5016 * lisp.h (Qframep): Remove decl. frame.h declares this.
5017 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
5018 since they're meant for Lisp fixnum values.
5020 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
5022 * window.c (Fwindow_combination_limit): Revert to the only
5023 required argument and adjust docstring as suggested in
5024 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
5025 by Martin Rudalics <rudalics@gmx.at>.

5076 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
5078 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
5079 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
5080 file descriptor 2 for standard error. (Bug#12805)
5082 2012-11-05 Chong Yidong <cyd@gnu.org>
5084 * process.c (wait_reading_process_output): Revert previous change.
5086 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
5088 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
5089 This removes code that has been obsolete since around 1990.
5090 * callproc.c (Fcall_process):
5092 * process.c (create_process):
5093 * term.c (dissociate_if_controlling_tty):
5094 Assume setsid exists.
5095 * callproc.c (child_setup): Assume setpgid exists and behaves as
5096 per POSIX.1-1988 or later.
5097 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
5098 * emacs.c (shut_down_emacs):
5099 * sysdep.c (sys_suspend, init_foreground_group):
5100 Assume getpgrp behaves as per POSIX.1-1998 or later.
5101 * msdos.c (setpgrp): Remove.
5102 (tcgetpgrp, setpgid, setsid): New functions.
5103 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
5104 * term.c (no_controlling_tty): Remove; unused.
5105 * w32proc.c (setpgrp): Remove.
5106 (setsid, tcgetpgrp): New functions.
5108 Simplify by assuming __fpending.
5109 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
5110 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
5111 Do not assume that __fpending's result fits in int.
5113 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
5115 Remove EMACS_OUTQSIZE+sleep hack.
5116 * dispnew.c (update_frame_1): Remove hack for terminals slower
5117 than 2400 bps, which throttled Emacs by having it sleep.
5118 This code hasn't worked since at least 2007, when the multi-tty stuff
5119 was added, and anyway those old terminals are long dead.
5120 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
5121 without the dispnew.c change, as dispnew.c doesn't include systty.h.
5123 Fix data-loss with --version (Bug#9574).
5124 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
5125 as we can't assume that emacs_strerror is initialized, and strerror
5126 is good enough here.
5127 (main): Invoke atexit earlier, to catch earlier instances of
5128 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
5130 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
5132 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
5133 (keyDown): Remap keypad keys to X11 virtual key codes.
5135 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
5137 Fix data-loss with --batch (Bug#9574).
5138 * emacs.c: Include <close-stream.h>.
5139 (close_output_streams): New function.
5140 (main): Pass it to atexit, so that Emacs closes stdout and stderr
5141 and handles errors appropriately.
5142 (Fkill_emacs): Don't worry about flushing, as close_output_stream
5145 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
5146 The symptom is a diagnostic "GLib-WARNING **: In call to
5147 g_spawn_sync(), exit status of a child process was requested but
5148 SIGCHLD action was set to SIG_IGN and ECHILD was received by
5149 waitpid(), so exit status can't be returned." The diagnostic
5150 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
5151 The real bug is a race condition between Emacs and glib: Emacs
5152 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
5153 so that glib can't find it. Work around the bug by invoking
5154 waitpid only on subprocesses that Emacs itself creates.
5155 * process.c (create_process, record_child_status_change):
5156 Don't use special value -1 in pid field, as the caller now must
5157 know the pid rather than having the callee infer it.
5158 The inference was sometimes incorrect anyway, due to another race.
5159 (create_process): Set new 'alive' member if child is created.
5160 (process_status_retrieved): New function.
5161 (record_child_status_change): Use it.
5162 Accept negative 1st argument, which means to wait for the
5163 processes that Emacs already knows about. Move special-case code
5164 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
5165 processes that have already been waited for, by testing and
5166 clearing new 'alive' member.
5167 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
5168 now does this internally.
5169 (handle_child_signal): Let record_child_status_change do all
5170 the work, since we do not want to reap all exited child processes,
5171 only the child processes that Emacs itself created.
5172 * process.h (Lisp_Process): New boolean member 'alive'.
5174 Omit duplicate definitions no longer needed with gcc -g3.
5175 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
5176 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
5177 Define only as macros. There's no longer any need to also define
5178 these symbols as enums or as constants, since we now assume
5179 gcc -g3 when debugging.
5181 2012-11-03 Eli Zaretskii <eliz@gnu.org>
5183 * lisp.mk: Adjust comments to the fact that term/internal is now
5184 loaded from loadup.el.
5186 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5187 (msdos_fatal_signal): New function.
5188 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5191 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5192 for GCC versions before 4.
5193 (emacs_raise): Define to call msdos_fatal_signal.
5195 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5196 iterator when starting in the middle of a display or overlay
5199 2012-11-03 Chong Yidong <cyd@gnu.org>
5201 * process.c (wait_reading_process_output): Clean up the last
5204 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5206 * process.c (wait_reading_process_output): Avoid a race condition
5207 with SIGIO delivery (Bug#11536).
5209 2012-11-03 Chong Yidong <cyd@gnu.org>
5211 * buffer.c (cursor_type): Untabify docstring.
5213 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5215 * frame.h (struct frame): Drop can_have_scroll_bars member
5216 which is meaningless for a long time. Adjust comments.
5217 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
5218 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
5220 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5222 * window.c (decode_next_window_args): Update window arg after
5223 calling decode_live_window and so fix crash reported at
5224 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
5225 by Juanma Barranquero <lekktu@gmail.com>.
5226 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
5227 * font.c (Ffont_at): Likewise.
5229 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
5231 * widget.c (resize_cb): New function.
5232 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
5233 (EmacsFrameResize): Check if all is up to date before changing frame
5236 2012-11-02 Eli Zaretskii <eliz@gnu.org>
5238 Implement backtrace output for fatal errors on MS-Windows.
5239 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
5240 (BACKTRACE_LIMIT_MAX): New macro.
5241 (w32_backtrace): New function.
5242 (emacs_abort): Use w32_backtrace when the user chooses not to
5243 attach a debugger. Update the text of the abort dialog.
5245 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5247 Window-related stuff cleanup here and there.
5248 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
5249 Use decode_any_window.
5250 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
5251 * xdisp.c (Fformat_mode_line): Likewise.
5252 * font.c (Ffont_at): Use decode_live_window.
5253 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
5254 * window.c (decode_next_window_args): Likewise.
5255 (decode_any_window): Remove static.
5256 * window.h (decode_any_window): Add prototype.
5257 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
5258 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
5261 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5263 Remove pad from struct input_event.
5264 * termhooks.h (struct input_event): Remove padding field.
5266 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5267 member is never cons for a long time. Adjust comment.
5268 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5269 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5270 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5271 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5273 2012-11-01 Eli Zaretskii <eliz@gnu.org>
5275 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
5277 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5279 Fix crash when using Emacs as commit editor for git (Bug#12697).
5280 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5281 and it is configured in conf_post.h.
5282 (Fcall_process): Don't invoke both setsid and setpgid; the former
5283 is enough, if it exists.
5284 * callproc.c (Fcall_process, child_setup):
5285 * process.c (create_process): Use setpgid.
5286 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5288 * dispnew.c (init_display): Initialize the foreground group
5289 if we are running a tty display.
5290 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
5291 * lisp.h (init_foreground_group): New decl.
5292 * sysdep.c (inherited_pgroup): New static var.
5293 (init_foreground_group, tcsetpgrp_without_stopping)
5294 (narrow_foreground_group, widen_foreground_group): New functions.
5295 (init_sys_modes): Narrow foreground group.
5296 (reset_sys_modes): Widen foreground group.
5298 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
5300 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
5302 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5304 * minibuf.c (read_minibuf): Restore current buffer since
5305 choose_minibuf_frame calling Fset_frame_selected_window may
5306 change it (Bug#12766).
5308 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
5310 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
5312 2012-10-30 Kenichi Handa <handa@gnu.org>
5314 * font.c (Ffont_at): If WINDOW is specified and it is not
5315 displaying the current buffer, signal an error.
5317 2012-10-29 Daniel Colascione <dancol@dancol.org>
5319 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5320 In preparation for fixing bug#12739, move these functions from
5323 * coding.h, coding.c: ... to here, and compile them only when
5324 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5325 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5327 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5329 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5330 (timer_loop, getitimer, setitimer): Use it instead of
5331 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
5333 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
5336 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
5338 * nsterm.m (NO_APPDEFINED_DATA): New define.
5339 (last_appdefined_event_data): New variable
5340 (last_appdefined_event): Remove.
5341 (ns_select): Initialize t from last_appdefined_event_data instead
5342 of [last_appdefined_event data1].
5343 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
5344 remove last_appdefined_event (Bug#12698).
5346 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5348 * frame.c (x_set_font): Catch internal error.
5350 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5352 Avoid overflow in w32 implementation of interval timers.
5353 When possible, for ITIMER_PROF count only times the main thread
5355 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5356 'volatile ULONGLONG' types. All the other data which was
5357 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5358 (GetThreadTimes_Proc): New typedef.
5359 (w32_get_timer_time): New function, returns a suitable time value
5361 (timer_loop): Enter critical section when accessing ULONGLONG
5362 values of the itimer_data struct, as these accesses are no longer
5363 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5364 Remove unused variable.
5365 (init_timers): Initialize s_pfn_Get_Thread_Times.
5366 (start_timer_thread): Don't assign itimer->caller_thread here.
5367 (getitimer): Assign itimer->caller_thread here.
5368 (setitimer): Always call getitimer to get the value of ticks_now.
5369 (sys_spawnve): Avoid compiler warning about format mismatch.
5371 2012-10-26 Eli Zaretskii <eliz@gnu.org>
5373 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5374 mouse movement events if the menu bar is active. This avoids
5375 producing a busy "hour-glass" cursor by Windows if the mouse
5376 pointer is positioned over a tooltip shown for some menu item.
5378 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5380 Don't assume process IDs fit in int.
5381 * emacs.c (shut_down_emacs) [!DOS_NT]:
5382 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5383 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5384 Use pid_t, not int, to store process IDs, as 'int'
5385 is not wide enough on a few platforms (e.g., AIX and IRIX).
5387 2012-10-23 Kenichi Handa <handa@gnu.org>
5389 The following change is to make face-font-rescale-alist work
5390 correctly for non-ASCII fonts.
5392 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
5393 (font_open_for_lface): Handle Vface_font_rescale_alist.
5395 2012-10-23 Chong Yidong <cyd@gnu.org>
5397 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
5399 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
5401 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
5403 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
5405 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
5408 2012-10-21 Glenn Morris <rgm@gnu.org>
5410 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5412 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5414 Port to OpenBSD 5.1.
5415 * frame.c (Fmouse_position, Fmouse_pixel_position):
5416 * xdisp.c (produce_stretch_glyph):
5417 Declare local vars only when they're needed.
5418 This is clearer and avoids a warning on OpenBSD about unused vars.
5419 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
5420 This is safer, and avoids OpenBSD warnings about unused vars.
5421 * keyboard.c (record_menu_key): Remove unnecessary decl.
5422 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5423 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5424 as our definition clashes with OpenBSD's.
5425 * xfaces.c (load_face_colors, check_lface_attrs)
5426 (get_lface_attributes_no_remap, get_lface_attributes)
5427 (lface_fully_specified_p, x_supports_face_attributes_p)
5428 (tty_supports_face_attributes_p, face_fontset, realize_face)
5429 (realize_x_face, realize_tty_face):
5430 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5431 merely Lisp_Object *. This is more informative and avoids
5432 a warning on OpenBSD about accessing beyond an object's size.
5434 2012-10-20 Chong Yidong <cyd@gnu.org>
5436 * lread.c (Fload): Doc fix (Bug#12592).
5438 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
5440 * font.c (Ffont_at): Fix previous change.
5442 2012-10-19 Eli Zaretskii <eliz@gnu.org>
5444 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
5445 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
5448 * alloc.c (NSTATICS): Decrease to 0x800.
5450 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

5455 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
5457 * nsterm.m (ns_select): Check writefds before call to
5458 FD_ISSET (Bug#12668).
5460 2012-10-18 Daniel Colascione <dancol@dancol.org>
5462 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5463 (staticpro): If we run out of staticpro slots, die with an
5464 informative error instead of just calling emacs_abort.
5466 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5468 Fix two flaws reported by Dmitry Antipov.
5469 * window.c (Ftemp_output_buffer_show): Remove.
5470 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
5471 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
5473 2012-10-17 Eli Zaretskii <eliz@gnu.org>
5475 * makefile.w32-in ($(BLD)/w32.$(O)):
5476 ($(BLD)/vm-limit.$(O)):
5478 ($(BLD)/unexw32.$(O)):
5479 ($(BLD)/fileio.$(O)):
5480 ($(BLD)/dispnew.$(O)): Update dependencies.
5482 * w32term.h (w32_initialize_display_info, initialize_w32_display):
5485 * w32proc.c: Include ctype.h.
5487 * w32.h (init_environment, check_windows_init_file)
5488 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
5489 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
5490 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
5491 (sys_link): Add prototypes.
5493 * w32.c: Include w32select.h.
5494 (sys_access, e_malloc, sys_select): Add prototypes.
5495 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
5497 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
5499 * unexw32.c: Include lisp.h and w32.h.
5501 * term.c [WINDOWSNT]: Include w32term.h.
5503 * process.c [WINDOWSNT]: Add prototype of sys_select.
5505 * fileio.c [WINDOWSNT]: Include w32.h.
5507 * dispnew.c [WINDOWSNT]: Include w32.h.
5509 * cygw32.c (Fcygwin_convert_path_to_windows)
5510 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
5511 Lisp_Object values. (Bug#12661)
5513 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
5514 to Lisp_Object. (Bug#12661)
5516 2012-10-17 Kenichi Handa <handa@gnu.org>
5518 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
5521 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
5523 * buffer.c (Fkill_buffer): When unchaining the marker,
5524 reset its buffer pointer to NULL (Bug#12652).
5526 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
5528 Do not verify indirection counters of killed buffers (Bug#12579).
5529 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
5530 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
5532 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
5534 * alloc.c (Fmake_byte_code): Fix typo in comment.
5535 * print.c (print_interval): Define as static to match prototype.
5536 * indent.c (disptab_matches_widthtab, recompute_width_table):
5539 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
5541 * editfns.c (get_system_name): Remove.
5542 * lisp.h (get_system_name): Remove prototype.
5543 * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes.

5561 headers define to something incompatible.
5563 2012-10-14 Daniel Colascione <dancol@dancol.org>
5565 * image.c (init_tiff_functions, init_imagemagick_functions)
5566 (init_svg_functions): Fix cygw32 build break by using these
5567 functions only when WINDOWSNT _and_ HAVE_NTGUI.

5588 Fix some stat-related races.
5589 * fileio.c (Fwrite_region): Avoid race condition if a file is
5590 removed or renamed by some other process immediately after Emacs
5591 writes it but before Emacs stats it. Do not assume that stat (or
5593 * image.c (slurp_file): Resolve the file name with fopen + fstat
5594 rather than stat + fopen.

5612 is zero (Bug#12384).
5614 2012-10-12 Juanma Barranquero <lekktu@gmail.com>

5620 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
5622 * fileio.c (check_existing): New function.
5623 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
5624 instead of calling 'stat', when what's needed is to check whether
5625 a file exists. This avoids expensive system calls on MS-Windows.
5628 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
5630 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

5635 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
5637 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

5677 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
5679 * marker.c (cached_modiff): EMACS_INT, not int.
5681 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
5682 instead of having a wrong decl.
5683 * nsmenu.m (waiting_for_input): Remove wrong decl.
5685 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

5718 Use bool for boolean.
5719 * keyboard.c (timers_run, swallow_events)
5720 (detect_input_pending_run_timers):
5721 * process.c (wait_reading_process_output):
5722 Use unsigned for counter where wraparound-on-overflow is desired,
5723 since unsigned is guaranteed to have that behavior and signed is not.
5724 (read_char): Use ptrdiff_t for string length.
5725 (get_input_pending): Remove first argument, since it was always
5726 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5727 and behave as if it had that value. Return new value of
5728 input_pending. All callers changed.
5729 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5730 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5732 * keymap.c (push_key_description): Omit last arg, which was always 1.
5733 All callers changed.
5735 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
5737 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

5753 Don't include termopts.h.
5755 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5757 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5759 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5761 * commands.h (immediate_quit): Remove duplicate decl.
5763 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5765 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

5768 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5770 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5772 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5773 match what GetLastError returns. Explain why the function is
5776 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5777 'is_tooltip_frame', to avoid confusion with its global namesake.
5779 2012-10-08 Daniel Colascione <dancol@dancol.org>
5781 * xdisp.c (start_hourglass): Call w32_note_current_window when
5782 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5783 build that caused Emacs to display the hourglass cursor forever.
5785 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5786 which is broken under remote desktop, calculate the number of
5787 colors available for a display based on the display's number of
5788 planes and number of bits per pixel per plane. (bug#10397).
5790 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5792 * nsfont.m (Vfonts_in_cache): New variable.
5793 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5794 are used. Add cached fonts to Vfonts_in_cache.
5795 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5797 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5799 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5801 (FONT_H): Define after FRAME_H.
5802 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5803 Update dependencies.
5805 * w32term.c: Remove leftover declaration of keyboard_codepage.
5807 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5809 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5810 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5811 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5812 (GLOBAL_SOURCES): Add cygw32.c.
5813 ($(BLD)/unexw32.$(O)):
5815 ($(BLD)/w32console.$(O)):
5816 ($(BLD)/w32fns.$(O)):
5817 ($(BLD)/w32heap.$(O)):
5818 ($(BLD)/w32menu.$(O)):
5819 ($(BLD)/w32proc.$(O)): Add w32common.h.
5821 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5823 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5825 2012-10-08 Daniel Colascione <dancol@dancol.org>
5827 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5828 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5829 accidental message numbering hole. Change other messages to
5832 * w32select.h (HAVE_W32SELECT): Remove.
5834 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5835 w32common.h instead of w32heap.h.
5837 * w32heap.h (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 declarations to
5844 * w32heap.c: Include w32common.h.
5845 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5846 (w32_minor_version, w32_build_number, w32_subtype):
5847 Remove duplicate definitions.
5849 * w32fns.c: Include w32common.h; include w32heap.h only in
5852 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5853 Use `report_file_error' instead of `error' in order to better
5854 inform users of what went wrong. Increase NTGUI_UNICODE file
5855 dialog box file name length to 32k, the maximum allowed by the NT
5858 * w32common.h: New file.
5859 (ROUND_UP, ROUND_DOWN, get_page_size)
5860 (get_allocation_unit, get_processor_type, get_w32_major_version)
5861 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5862 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5863 (OS_NT, os_subtype, cache_system_info): Move here.
5865 * unexw32.c, unexcw.c: Include w32common.h.
5867 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5868 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5869 to call syms_of_w32select.
5871 * cygw32.h: Remove obsolete EXFUN declarations.
5873 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

5876 of w32inevt.o from SOME_MACHINE_OBJECTS.
5878 2012-10-08 Daniel Colascione <dancol@dancol.org>
5880 * image.c: Permanent fix for JPEG compilation issue --- limit
5881 jpeglib `boolean' redefinition to Cygwin builds.
5883 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5885 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5887 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5890 2012-10-08 Daniel Colascione <dancol@dancol.org>
5892 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5893 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5894 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5895 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5896 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5897 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5898 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5899 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5900 now a supported configuration.
5902 * Makefile.in: consolidate image variables into LIBIMAGE; add
5903 W32_OBJ and W32_LIBS. Compile new files.
5906 (_DebPrint) declare tracing facility for W32 debugging. We need
5907 to unify tracing later.
5909 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5910 unconditional use of W32 Unicode functions. Cygwin runs only on
5911 100% Unicode operating systems.
5913 * cygw32.c: New file. Define Cygwin-specific facilities.
5914 (Fcygwin_convert_path_to_windows)
5915 (Fcygwin_convert_path_from_windows): New user functions for
5916 accessing Cygwin path-munging routines.
5918 * cygw32.h: New file.
5919 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5920 UTF-16LE strings temporarily inside non-Lisp-visible string
5923 (w32_strerror): Just what it says on the tin.
5925 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5926 also run for Cygwin; both systems have the same problem with using
5927 GUI facilities in a forked child. Also call syms_of_cygw32,
5928 syms_of_w32select in correct places.
5930 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5931 needs fork-then-exec for daemon launching.
5933 * font.h: Include frame.h.
5935 * image.c: Use the image library cache machinery only when we're
5936 compiling for native WINDOWSNT; Cygwin can use shared libraries
5937 like any other Unixlike system.
5939 * keyboard.c: Clarify a comment regarding the input loop.
5941 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5942 functions directly instead of trying to detect at runtime that our
5943 host operating system supports them. We make this change for two
5944 reasons: Cygwin lacks support for the multibyte character
5945 conversion functions used by the legacy menu code, and Cygwin
5946 never needs to rely on non-Unicode APIs.
5948 * unexw32.c (hinst): Declare extern.
5950 * w32.c: Change header order;
5951 (w32_strerror): Move to w32fns.c because we need it for
5952 non-WINDOWSNT builds.
5954 * w32.h: Add #error macro to make sure we don't include w32.h for
5955 Cygwin builds. Remove w32select declarations.
5957 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5958 w32fns.c. w32console.c is WINDOWSNT-only.
5960 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5961 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5963 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5964 (w32_major_version, w32_minor_version, w32_build_number)
5965 (os_subtype, sound_type): Define here
5966 (w32_defined_color): Make color parameter const for consistency
5967 with other _defined_color functions.
5968 (w32_createwindow): Unconditionally call w32_init_class instead of
5969 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5970 through the code is complex and unnecessary because class
5971 registration is practically free.
5972 (w32_name_of_message): New EMACSDEBUG-only function.
5973 (Fset_message_beep): Move here
5974 (Fx_open_connection): Require that the display name for Windows be
5975 "w32" for consistency, emacsclient disambiguation, and maybe, one
5976 day, multi-window-system support.
5977 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5978 Cygwin files for W32 GUI facilities, since these clearly don't
5979 expect Cygwin names.
5980 (_DebPrint): Define.
5981 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5982 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5983 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5984 (w32_last_error): Remove.
5986 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5988 * w32heap.c (syspage_mask): Declare here.
5989 (cache_system_info): Remove.
5991 * w32inevt.c (faked_key): Define globally, not statically.
5992 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5993 (w32_console_toggle_lock_key): Move to w32fns.c.
5995 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5997 * w32proc.c (_DebPrint): Move to w32fns.c.
5998 * w32select.c: Include string.h, stdio.h for Cygwin.
5999 * w32select.h: New File.
6001 * w32term.c: Include io.h for non-CYGWIN builds; needed for
6003 (w32_message_fd): New variable. Under Cygwin, holds the file
6004 descriptor the system used to tell us about pending thread
6007 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
6008 that prevented compilation under non-WINDOWSNT systems.
6010 (w32_initialize): Open /dev/windows and assign it to
6011 w32_message_fd. Provide w32 feature.
6013 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
6014 (WM_EMACS_INPUT_READY): add.
6015 (prepend_msg, w32_message_fd): Declare globally.
6018 (keyboard_handle): Use only when WINDOWSNT.
6019 (notify_msg_ready): New function. Posts a message to the main
6020 thread's message queue under CYGWIN, which wakes up the main
6021 thread from select(2) by making the /dev/windows file descriptor
6022 ready. Under WINDOWSNT, it sets an event the same way the old
6025 (post, prepend_msg): Actually call notify_msg_ready instead of
6026 setting the input event directly.
6028 2012-10-07 Eli Zaretskii <eliz@gnu.org>
6030 * ralloc.c (relinquish): If a heap is ready to be relinquished,
6031 but it still has blocs in it, don't return it to the system,
6032 instead of aborting. (Bug#12402)
6034 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
6036 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

6067 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
6069 Improve sys_siglist detection.
6070 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
6071 defined as a macro, as is done in Solaris.
6072 (sys_siglist_entries): New macro.
6073 (save_strsignal): Use it.
6074 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
6075 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
6077 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
6079 * nsfns.m (Fx_create_frame): Call x_default_parameter with
6080 fullscreen/Fullscreen.
6082 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
6083 tobar_height is new.
6085 * nsterm.m (x_make_frame_visible): Check for fullscreen.
6086 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
6087 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

6096 (canBecomeMainWindow): New function.
6098 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
6100 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
6102 2012-10-05 Eli Zaretskii <eliz@gnu.org>
6104 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
6106 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
6107 that time stamps of directories could also be changed.
6108 Don't request the too broad GENERIC_WRITE, only the more restrictive
6109 FILE_WRITE_ATTRIBUTES access rights.
6111 * fileio.c (Fset_file_times): Special-case ignoring errors for
6112 directories only on MSDOS, not on MS-Windows.
6114 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
6116 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
6118 2012-10-04 Eli Zaretskii <eliz@gnu.org>
6120 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
6121 see whether CreateFile failed.
6123 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
6125 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
6126 to avoid similar races.
6127 * keyboard.c (pending_signals): Now bool, not int.
6129 Port timers to OpenBSD, plus check for timer failures.
6130 OpenBSD problem reported by Han Boetes.
6131 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
6133 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
6134 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
6135 like OpenBSD, which has timer_settime but does not declare it.
6136 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
6137 whether to use itimerspec-related primitives. All uses of
6138 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
6140 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6142 * profiler.c (handle_profiler_signal): Fix a malloc race
6143 that caused Emacs to hang on Fedora 17 when profiling Lisp.
6145 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
6147 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
6149 2012-10-02 Eli Zaretskii <eliz@gnu.org>
6151 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
6152 consistent with the change in return value of 'safe_strsignal'.
6154 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6156 Prefer plain 'static' to 'static inline' (Bug#12541).
6157 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
6158 (bidi_set_sor_type, bidi_push_embedding_level)
6159 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

6164 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6165 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
6166 Now 'static', not 'static inline'.
6168 Count overruns when profiling; change units to ns.
6169 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
6170 Give extra weight to samples after overruns, to attempt to count
6171 the time more accurately.
6172 (setup_cpu_timer): Change sampling interval units from ms to ns, since
6173 the underlying primitives nominally do ns.
6174 (Fprofiler_cpu_start): Document the change. Mention that
6175 the sampling intervals are only approximate.
6177 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6179 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
6181 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
6182 case for the special 0 coding-system.
6184 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
6185 (Fmake_overlay): Remove redundant tests.
6186 (fix_start_end_in_overlays): Remove redundant recentering.
6188 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
6190 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
6191 Update dependencies.
6193 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6195 Fix a malloc race condition involving strsignal.
6196 A signal can arrive in the middle of a malloc, and Emacs's signal
6197 handler can invoke strsignal, which can invoke malloc, which is
6198 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6199 Fix it by altering the signal handler so that it does not invoke
6201 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6202 * process.c (status_message): Use const pointer, in case strsignal
6203 is #defined to safe_strsignal.
6204 * sysdep.c (sys_siglist, init_signals): Always define and
6205 initialize a substitute sys_siglist if the system does not define
6206 one, even if HAVE_STRSIGNAL.
6207 (safe_strsignal): Rename from strsignal. Always define,
6208 using sys_siglist. Return a const pointer.
6209 * syssignal.h (safe_strsignal): New decl.
6210 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6212 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6214 * w32proc.c (timer_loop): Fix code that waits for timer
6215 expiration, to avoid high CPU usage.
6217 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6219 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6220 (sweep_weak_table): Remove redundant prototypes.
6222 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6224 * emacs.c: Move the inclusion of TERM_HEADER after including
6225 windows.h on WINDOWSNT. This avoids compilation problems with
6228 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6230 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6231 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6232 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6233 as the previous version used 'void *'.
6235 * ralloc.c (ROUNDUP): Fix last change.
6236 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6239 * w32proc.c <disable_itimers>: New static flag.
6240 (init_timers): Initialize it to zero, after creating the critical
6241 sections used by the timer threads.
6242 (term_timers): Set to 1 before deleting the critical sections.
6243 (getitimer, setitimer): If disable_itimers is non-zero, return an
6244 error indication without doing anything. Reported by Fabrice
6245 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6246 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6248 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6251 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6252 term_ntproc after all the other bookkeeping, to get timers working
6253 as long as possible.
6255 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6257 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6258 Suggested by Juri Linkov in
6259 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6261 Prefer plain 'static' to 'static inline' (Bug#12541).
6262 With static functions, modern compilers inline pretty well by
6263 themselves; advice from programmers often hurts as much as it helps.
6264 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6265 this change shrinks the text size of the Emacs executable by 1.1%
6266 without affecting CPU significantly in my benchmark.
6267 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

6342 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
6343 Now 'static', not 'static inline'.
6346 (bidi_copy_it): Do the whole copy with a single memcpy.
6347 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
6349 Revert the FOLLOW-SYMLINKS change for file-attributes.
6350 Doing it right would require several changes to Tramp, and there's
6351 not enough time to get that tested before the freeze today.
6352 * dired.c (directory_files_internal, Ffile_attributes):
6355 * frame.c (x_report_frame_params): Port better to wider ints.
6356 Do not assume that EMACS_UINT is the same width as uprintmax_t,
6357 or that pointers can be printed in 15 decimal digits.
6358 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
6360 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

6394 * vm-limit.c (lim_data): Now size_t.
6395 (check_memory_limits): Adjust prototypes of real_morecore and
6396 __morecore to receive argument of type ptrdiff_t. Use size_t for

6538 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
6539 Suggested by Eli Zaretskii in
6540 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
6542 2012-09-30 Eli Zaretskii <eliz@gnu.org>
6544 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
6545 HAVE_TIMER_SETTIME is defined.
6547 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6549 Profiler improvements: more-accurate timers, overflow checks.
6550 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6551 signal.h, setjmp.h. Include systime.h instead.
6552 (saturated_add): New function.
6553 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
6554 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.

6557 (enum profiler_cpu_running): New enum.
6558 (profiler_cpu_running): Now of that enum type, not bool.
6559 All uses changed to store the new value.
6560 (handle_profiler_signal): Rename from sigprof_handler_1,
6561 for consistency with other handlers. Do not check whether
6562 cpu_log is a hash-table if garbage collecting, since it
6563 doesn't matter in that case.
6564 (deliver_profiler_signal): Rename from sigprof_handler,
6565 for consistency with other handlers.
6566 (setup_cpu_timer): New function, with much of what used to be in
6567 Fprofiler_cpu_start. Check for out-of-range argument.
6568 Prefer timer_settime if available, and prefer
6569 thread cputime clocks, then process cputime clocks, then
6570 monotonic clocks, to the old realtime clock. Use make_timeval
6571 to round more-correctly when falling back to setitimer.
6572 (Fprofiler_cpu_start): Use it.
6573 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6574 Don't assume that passing NULL as the 2nd argument of setitimer
6575 is the same as passing a pointer to all-zero storage.
6576 Ignore SIGPROF afterwards.
6577 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6578 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6579 non-fatal signal handlers. Ignore SIGPROF on startup.
6580 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6581 in profiler.c, since sysdep.c now uses it.
6583 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
6584 Suggested by Eli Zaretskii in

6638 * charset.c, charset.h (maybe_unify_char): Now static.
6639 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6640 Since this stuff is now private to charset.c, there's no need for
6641 a public macro and no need to inline by hand.

6713 (sigaction): Rewrite to call sys_signal instead of duplicating its
6715 (sys_kill): Improve commentary.
6717 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6718 consistency with a signature of a signal handler. All callers
6720 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6721 install term_ntproc as a signal handler for SIGABRT, as that
6722 should be done by the dumped Emacs.
6724 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6726 * w32select.c (term_w32select): Protect against repeated
6727 invocation by setting clipboard_owner to NULL after calling

6793 (interruptible_wait_for_termination):
6794 Move these decls from lisp.h to syswait.h, since they use pid_t.
6795 Needed on FreeBSD; see Herbert J. Skuhra in

6845 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6846 fatal_error_backtrace.
6848 * w32proc.c (sys_kill): Undo last change: don't do anything when

6899 Avoid recursive loop if there's a fatal error in the function itself.
6900 * atimer.c (pending_atimers):
6901 * blockinput.h: Don't include "atimer.h"; no longer needed.
6902 (interrupt_input_pending): Remove. All uses removed.
6903 pending_signals now counts both atimers and ordinary interrupts.
6904 This is less racy than having three separate pending-signal flags.
6905 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6907 Rename from their upper-case counterparts BLOCK_INPUT,
6908 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6909 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6910 This makes it easier to access volatile variables more accurately.
6911 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6912 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6913 that's more reliable if the code is buggy and sets
6914 interrupt_input_blocked to a negative value. All uses changed.
6915 * atimer.c (deliver_alarm_signal):
6916 Remove. No need to deliver this to the parent; any thread can
6917 handle this signal now. All uses replaced by underlying handler.
6918 * atimer.c (turn_on_atimers):
6919 * dispnew.c (handle_window_change_signal):
6920 * emacs.c (handle_danger_signal):
6921 * keyboard.c (kbd_buffer_get_event):
6922 Don't reestablish signal handler; not needed with sigaction.
6923 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6925 Rework to avoid unnecessary accesses to volatile variables.
6926 (UNBLOCK_INPUT_TO): Now a function.
6927 (totally_unblock_input, unblock_input): New decls.
6928 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6929 (init_data): Remove. Necessary stuff now done in init_signal.
6930 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6931 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6932 (fatal_error_code): Remove; no longer needed.
6933 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6934 it doesn't always backtrace. All uses changed. No need to reset
6935 signal to default, since sigaction and/or die does that for us now.
6936 Use emacs_raise (FOO), not kill (getpid (), FOO).
6937 (main): Check more-accurately whether we're dumping.
6938 Move fatal-error setup to sysdep.c
6939 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6940 * gtkutil.c (xg_get_file_name, xg_get_font):
6941 Remove no-longer-needed signal-mask manipulation.
6942 * keyboard.c, process.c (POLL_FOR_INPUT):
6943 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6944 * keyboard.c (read_avail_input): Remove.
6945 All uses replaced by gobble_input.
6946 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6947 (kbd_buffer_store_event_hold, gobble_input):
6948 (record_asynch_buffer_change) [USABLE_SIGIO]:
6949 (store_user_signal_events):
6950 No need to mess with signal mask.
6951 (gobble_input): If blocking input and there are terminals, simply
6952 set pending_signals to 1 and return. All hooks changed to not
6953 worry about whether input is blocked.
6954 (process_pending_signals): Clear pending_signals before processing
6955 them, in case a signal comes in while we're processing.
6956 By convention callers now test pending_signals before calling us.
6957 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6958 New functions, to support changes to blockinput.h.
6959 (handle_input_available_signal): Now extern.
6960 (reinvoke_input_signal): Remove. All uses replaced by
6962 (quit_count): Now volatile, since a signal handler uses it.
6963 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6964 All callers changed. Block SIGINT only if not already blocked.
6965 Clear sigmask reliably, even if Fsignal returns, which it can.
6966 Omit unnecessary accesses to volatile var.
6967 (quit_throw_to_read_char): No need to restore sigmask.
6968 * keyboard.c (gobble_input, handle_user_signal):
6969 * process.c (wait_reading_process_output):
6970 Call signal-handling code rather than killing ourselves.
6971 * lisp.h: Include <float.h>, for...
6972 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6973 (pending_signals): Now volatile.
6974 (syms_of_data): Now const if IEEE floating point.
6975 (handle_input_available_signal) [USABLE_SIGIO]:
6976 (terminate_due_to_signal, record_child_status_change): New decls.
6977 * process.c (create_process): Avoid disaster if memory is exhausted
6978 while we're processing a vfork, by tightening the critical section
6980 (send_process_frame, process_sent_to, handle_pipe_signal)
6981 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6983 (send_process): No need for setjmp/longjmp any more, since the
6984 SIGPIPE stuff is now gone. Instead, report an error if errno
6986 (record_child_status_change): Now extern. PID and W are now args.
6987 Return void, not bool. All callers changed.
6988 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6989 Remove. All uses removed. This bug should be fixed now in a
6991 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6992 and record the child status change directly. This avoids the
6993 need to futz with the signal mask.
6994 (process_fatal_action): Move here from emacs.c.
6995 (emacs_sigaction_flags): New function, containing
6996 much of what used to be in emacs_sigaction_init.
6997 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6998 caught by emacs, to make races less likely.
6999 (deliver_process_signal): Rename from handle_on_main_thread.
7001 (BACKTRACE_LIMIT_MAX): Now at top level.
7002 (thread_backtrace_buffer, threadback_backtrace_pointers):
7004 (deliver_thread_signal, deliver_fatal_thread_signal):
7005 New functions, for more-accurate delivery of thread-specific signals.
7006 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
7007 (deliver_arith_signal): Handle in this thread, not
7008 in the main thread, since it's triggered by this thread.
7009 (maybe_fatal_sig): New function.
7010 (init_signals): New arg DUMPING so that we can be more accurate
7011 about whether we're dumping. Caller changed.
7012 Treat thread-specific signals differently from process-general signals.
7013 Block all signals while handling fatal error; that's safer.
7014 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
7016 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
7017 Ignore SIGPIPE unless batch.
7018 (emacs_backtrace): Output backtrace for the appropriate thread,
7019 which is not necessarily the main thread.
7020 * syssignal.h: Include <stdbool.h>.
7021 (emacs_raise): New macro.
7022 * xterm.c (x_connection_signal): Remove; no longer needed
7023 now that we use sigaction.
7024 (x_connection_closed): No need to mess with sigmask now.
7025 (x_initialize): No need to reset SIGPIPE handler here, since
7026 init_signals does this for us now.
7028 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
7030 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
7031 background rect may be larger (Bug#12245).
7033 2012-09-23 Chong Yidong <cyd@gnu.org>
7035 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
7037 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7039 * .gdbinit: Just stop at fatal_error_backtrace.
7040 See Stefan Monnier's request in
7041 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
7042 Remove no-longer-used query of system type.
7044 2012-09-22 Chong Yidong <cyd@gnu.org>
7046 * search.c (Freplace_match): Doc fix (Bug#12325).
7048 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
7050 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
7051 (Fline_end_position): Doc fix.
7053 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
7055 2012-09-22 Chong Yidong <cyd@gnu.org>
7057 * dispextern.h (struct image_type): Add new slot, storing a type
7058 initialization function.
7060 * image.c (define_image_type): Call the image initializer function
7061 if it is defined. Arguments and return value changed.
7062 (valid_image_p, make_image): Callers changed.
7063 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
7064 (gif_type, imagemagick_type, svg_type, gs_type):
7065 Add initialization functions.
7066 (Finit_image_library): Call lookup_image_type.
7067 (CHECK_LIB_AVAILABLE): Macro deleted.
7068 (lookup_image_type): Call define_image_type here, rather than via
7069 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
7070 (syms_of_image): Move define_image_type calls for xbm_type and
7071 pbm_type to lookup_image_type.
7073 2012-09-22 Eli Zaretskii <eliz@gnu.org>
7075 * keyboard.c (timer_check_2): Move calculation of 'timers' and
7076 'idle_timers' from here ...
7077 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
7078 lists, to avoid infloops when the timer does something stupid,
7079 like reinvoke itself with the same or smaller time-out.
7082 2012-09-22 Martin Rudalics <rudalics@gmx.at>
7084 * window.c (Fsplit_window_internal): Handle only Qt value of
7085 Vwindow_combination_limit separately.
7086 (Qtemp_buffer_resize): New symbol.
7087 (Vwindow_combination_limit): New default value.
7090 2012-09-22 Eli Zaretskii <eliz@gnu.org>
7092 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
7093 the new overlay string. (Bug#10159)
7095 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7097 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
7098 or that fprintf is async-signal-safe. POSIX doesn't require
7101 2012-09-22 Chong Yidong <cyd@gnu.org>
7103 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
7106 2012-09-22 Kenichi Handa <handa@gnu.org>
7108 * composite.c (composition_reseat_it): Handle the case that a
7109 grapheme cluster is not covered by a single font (Bug#12352).
7111 2012-09-21 Chong Yidong <cyd@gnu.org>
7113 * image.c (define_image_type): Avoid adding duplicate types to
7114 image_types (Bug#12463). Suggested by Jörg Walter.
7116 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7118 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
7119 (print_load_command_name): Add case LC_DATA_IN_CODE.
7120 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
7122 2012-09-21 Glenn Morris <rgm@gnu.org>
7124 * eval.c (Frun_hook_with_args_until_success)
7125 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
7127 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
7129 * fileio.c (Ffile_selinux_context): Only call freecon when
7130 lgetfilecon succeeded.
7131 (Fset_file_selinux_context): Likewise. (Bug#12444)
7133 2012-09-21 Eli Zaretskii <eliz@gnu.org>
7135 * xdisp.c (try_window_reusing_current_matrix): Under bidi
7136 reordering, locate the cursor by calling set_cursor_from_row; if
7137 that fails, clear the desired glyph matrix before returning a
7138 failure indication to the caller. Fixes leaving garbled display
7139 when fast scrolling with a down-key. (Bug#12403)
7140 (compute_stop_pos_backwards): Fix a typo that caused crashes while
7141 scrolling through multibyte text.
7143 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
7145 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
7146 calling mark_vectorlike since that's the one that marks the window.
7147 (mark_discard_killed_buffers): Mark the final cdr.
7148 * window.h (struct window): Move prev/next_buffers to the
7149 non-standard fields.
7150 * window.c (make_window): Initialize prev/next_buffers manually.
7152 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
7154 Omit unused arg EXPECTED from socket hooks.
7155 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
7156 * nsterm.m (ns_term_init):
7157 * termhooks.h (struct terminal.read_socket_hook):
7158 * w32inevt.c (w32_console_read_socket):
7159 * w32term.c (w32_read_socket):
7160 * xterm.c (XTread_socket):
7161 Omit unused arg EXPECTED. All callers changed.
7162 (store_user_signal_events): Return void, not int, since callers no
7163 longer care about the return value. All uses changed.
7165 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
7167 * w32gui.h (XParseGeometry): Do not declare.
7169 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
7171 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
7172 Ignore 'expected'. See Eli Zaretskii in
7173 <http://bugs.gnu.org/12471#8> (last line).
7175 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
7176 (XParseGeometry): Now static. Substitute extremal values for
7177 values that are out of range.
7179 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7181 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7183 * nsfns.m (XParseGeometry): Remove.
7184 (Fx_create_frame): Call x_set_offset to correctly interpret
7185 top_pos in geometry.
7187 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7188 (Fx_parse_geometry): If there is a space in string, call
7189 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7191 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7193 * search.c (scan_buffer): Use character positions in calls to
7194 region_cache_forward and region_cache_backward, not byte
7195 positions. (Bug#12196)
7197 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7198 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7200 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7201 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7202 emacs_blocked_malloc, now deleted.
7204 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7206 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7207 The workaround was for improving performance on Solaris 2.4, but
7208 is getting in the way now. Emacs will still work if someone is
7209 still running Solaris 2.4 in a museum somewhere; Sun dropped
7210 support for Solaris 2.4 in 2003.
7211 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7212 * process.c (create_process) [HAVE_WORKING_VFORK]:
7213 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7214 since Emacs no longer uses vfork on that platform.
7216 2012-09-17 Glenn Morris <rgm@gnu.org>
7218 * emacs.c: Use COPYRIGHT.
7220 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7222 Remove configure's --without-sync-input option (Bug#12450).
7223 When auditing signal-handling in preparation for cleaning it up,
7224 I found that SYNC_INPUT has race conditions and would be a real
7225 pain to fix. Since it's an undocumented and deprecated
7226 configure-time option, now seems like a good time to remove it.
7227 Also see <http://bugs.gnu.org/11080#16>.
7228 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7229 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7230 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7231 (malloc_hysteresis):
7232 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7233 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7234 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7235 (dont_register_blocks, bytes_used_when_reconsidered)
7236 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7237 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7238 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7239 Remove. All uses removed.
7240 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7241 implementation, one that depends on whether the new macro
7242 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7244 * atimer.c (run_timers, handle_alarm_signal):
7245 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7246 (handle_async_input, process_pending_signals)
7247 (handle_input_available_signal, init_keyboard):
7248 * nsterm.m (ns_read_socket):
7249 * process.c (wait_reading_process_output):
7250 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7251 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7253 * xterm.c (XTread_socket):
7255 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7256 * eval.c (handling_signal): Remove. All uses removed.
7257 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7258 All uses replaced with the SYNC_INPUT version.
7259 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7261 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7264 * font.c (Ffont_shape_gstring): Remove unused local.
7266 2012-09-16 Glenn Morris <rgm@gnu.org>
7268 * Makefile.in (clean): No longer run nextstep's clean.
7270 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7272 (ns-app): Move here from ns.mk, and simplify.
7273 (clean): Simplify nextstep entry.
7274 * ns.mk: Remove file.
7276 2012-09-17 Kenichi Handa <handa@gnu.org>
7278 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7279 not covert the last few charactes.
7281 2012-09-16 Kenichi Handa <handa@gnu.org>
7283 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7284 here, but just check the validity of glyphs in the glyph-string.
7286 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7288 * window.c (Fwindow_parameter, Fset_window_parameter):
7289 Accept any window as argument (Bug#12452).
7291 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7293 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7294 to ns_term_init to avoid memory leak.
7296 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7297 explicit retain/release.
7298 (ns_term_init): Only allow one display. Initialize outerpool and
7301 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7303 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7304 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7305 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7306 the Microsoft problem in a different way, by altering ../nt/config.nt.
7308 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7323 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7324 by lisp.h. This completes removal of setjmp.h inclusion
7325 erroneously announced in the previous commit. (Bug#12446)
7327 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7330 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7331 not defined as a macro. The latter happens on MS-Windows.
7334 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7336 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7337 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7338 Some instances of '#include <setjmp.h>' removed, if the
7339 only reason for the instance was because "lisp.h" was included.
7340 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7341 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7342 and _longjmp with the new symbols. Emacs already uses _setjmp if
7343 available, so this change affects only POSIXish hosts that have
7344 sigsetjmp but not _setjmp, such as some versions of Solaris and
7345 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7346 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7347 (png_load_body) [HAVE_PNG]:
7348 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7349 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7350 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7351 since PNG requires jmp_buf. This is the only exception to the
7352 general rule that we now use sys_setjmp and sys_longjmp.
7353 This exception is OK since this code does not change the signal
7354 mask or longjmp out of a signal handler.
7356 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7358 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7359 Include "syssignal.h", for 'main_thread'.
7361 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7363 Avoid out-of-range marker position (Bug#12426).
7364 * insdel.c (replace_range, replace_range_2):
7365 Adjust markers before overlays, as suggested by comments.
7366 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7367 Remove redundant check before calling offset_intervals.
7369 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7371 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7372 current buffer (Bug#12387).
7374 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7376 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7378 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7380 Use a more backwards-compatible timer format (Bug#12430).
7381 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7382 vector element, not from the 4th, since PSECS is now at the end.
7383 (Fcurrent_idle_time): Doc fix.
7385 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7387 Function to mark objects and remove killed buffers at once.
7388 * alloc.c (discard_killed_buffers): Rename to ...
7389 (mark_discard_killed buffers) ... new name. Add marking
7390 of remaining objects. Fix comment. Adjust users.
7391 (mark_object): Do not touch frame buffer lists here.
7392 * frame.c (delete_frame): Reset frame buffer lists here.
7394 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7396 Better workaround for GNOME bug when --enable-gcc-warnings.
7397 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7398 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7399 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7401 Simplify SIGIO usage (Bug#12408).
7402 The code that dealt with SIGIO was crufty and confusing, e.g., it
7403 played tricks like "#undef SIGIO" but these tricks were not used
7404 consistently. Simplify mostly by not #undeffing standard symbols,
7405 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7406 or not as we please) rather than "defined SIGIO" (standard symbol
7407 that we probably shouldn't #undef).
7408 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7409 Modules that need it can include it.
7410 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7411 * dispextern.h (ignore_sigio): New decl.
7412 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7413 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7414 * emacs.c (shut_down_emacs):
7415 * keyboard.c (kbd_buffer_store_event_hold):
7416 Use ignore_sigio rather than invoking 'signal' directly.
7417 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7419 (FIONREAD, SIGIO): Do not #undef.
7420 (tty_read_avail_input): Use #error rather than a syntax error.
7421 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7422 for I_PIPE, used by SETUP_SLAVE_PTY.
7423 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7424 * sysdep.c (croak): Remove; no longer needed. This bit of
7425 temporary code, with Fred N. Fish's comment that it's temporary,
7426 has been in Emacs since at least 1992!
7427 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7428 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7429 * syssignal.h (croak): Remove decl.
7430 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7431 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7432 now that we're termios-only.
7433 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7434 * term.c (dissociate_if_controlling_tty): Use #error rather than
7437 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7438 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7439 to work around GNOME bug 683906.
7440 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7441 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7442 This works around GCC bug 54561.
7444 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7446 More fixes for 'volatile' and setjmp/longjmp.
7447 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7448 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7449 (png_load_body) [HAVE_PNG]:
7450 (jpeg_load_body) [HAVE_JPEG]:
7451 New function, with most of the old parent function's body.
7452 (png_load) [HAVE_PNG]:
7453 (jpeg_load) [HAVE_JPEG]:
7454 Invoke the new function, to avoid longjmp munging our locals.
7455 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7456 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7457 longjmp is passed 2, as the C standard doesn't guarantee this.
7458 Instead, store the failure code into mgr->failure_code.
7460 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7462 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7463 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7464 (syms_of_keyboard): Remove support for unread-command-char.
7466 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7468 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7469 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7470 violation. (Bug#12426)
7472 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7474 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7476 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7478 * eval.c: Add `inhibit-debugger'.
7479 (Qinhibit_debugger): New symbol.
7480 (call_debugger): Bind it instead of Qdebug_on_error.
7481 (maybe_call_debugger): Test Vinhibit_debugger.
7482 (syms_of_eval): Define inhibit-debugger.
7483 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7484 (syms_of_xdisp): Remove inhibit-debug-on-message.
7486 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7488 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7489 If a nonvolatile local variable is written before a _longjmp to
7490 the frame containing the variable, and is read after the _longjmp,
7491 the value read is indeterminate. Some local variables of type
7492 'struct handler' and 'struct catchtag' are used in this way, so
7493 mark each of their slots as volatile if the slot can be set before
7494 _longjmp and read afterwards.
7495 * lisp.h (struct handler): var and chosen_clause are now volatile.
7496 (struct catchtag): val, next, and pdlcount are now volatile.
7498 * bidi.c (bidi_push_it, bidi_pop_it):
7499 * fns.c (copy_hash_table):
7500 * image.c (define_image_type):
7501 * keyboard.c (kbd_buffer_store_event_hold):
7502 * process.c (Fprocess_send_eof):
7503 * xfaces.c (x_create_gc) [HAVE_NS]:
7504 * xgselect.c (xg_select):
7505 Prefer assignment to memcpy when either will do.
7507 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7508 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7509 time an item is removed. No need to mark this function 'inline';
7510 the compiler knows better than we do.
7512 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7514 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7515 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7516 to change_frame_size (Bug#12388).
7517 (windowDidResize:): Pass YES to updateFrameSize.
7519 * nsterm.h: Add delay parameter to updateFrameSize.
7521 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7523 Discard killed buffers from deleted window and frame objects.
7524 This reduces an amount of references to killed buffers and
7525 helps GC to reclaim them faster.
7526 * alloc.c (discard_killed_buffers): New function.
7527 (mark_object): Use it for deleted windows and frames.
7528 (mark_object): If symbol's value is set up for a killed buffer
7529 or deleted frame, restore its global binding.
7530 * data.c (swap_in_global_binding): Add GC notice.
7531 (swap_in_symval_forwarding): Use convenient set_blv_where.
7532 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7533 * window.h: ... to here.
7535 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7537 Convenient macro to check whether the buffer is live.
7538 * buffer.h (BUFFER_LIVE_P): New macro.
7539 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7540 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7542 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7544 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7545 composition cases (Bug#12364).
7547 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7548 overhang of succeeding glyphs overlapping box cursor.
7550 * w32term.c (x_draw_glyph_string): Likewise.
7552 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7554 Simplify, document, and port floating-point (Bug#12381).
7555 The porting part of this patch fixes bugs on non-IEEE platforms
7556 with frexp, ldexp, logb.
7557 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7559 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7560 support, by removing commented-out code and briefly listing the
7561 C89 functions excluded. The commented-out stuff was confusing
7562 maintenance, e.g., we thought we needed cbrt but it was commented out.
7563 (logb): Remove decl; no longer needed.
7564 (isfinite): New macro, if not already supplied.
7565 (isnan): Don't replace any existing macro.
7566 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7567 are present on all C89 platforms.
7568 (Ffrexp): Do not special-case zero, as frexp does the right thing
7570 (Flogb): Do not use logb, as it doesn't have the desired meaning
7571 on hosts that use non-base-2 floating point. Instead, stick with
7572 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7573 frexp, to avoid getting an unspecified result.
7575 * xdisp.c (Qinhibit_debug_on_message): Now static.
7577 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7579 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7580 NSBezierPath (Bug#12131).
7582 2012-09-10 Chong Yidong <cyd@gnu.org>
7584 * fns.c (Fdelq, Fdelete): Doc fix.
7586 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7588 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7589 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7591 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7593 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7594 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7597 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7599 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7600 left fringe if the window has a left margin. This avoids leaving
7601 traces of the cursor because its leftmost pixel is not drawn over.
7603 * dispnew.c (update_window_line): When the left margin area of a
7604 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7605 that screen line. (Bug#12277)
7607 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7609 Assume C89 or later for math functions (Bug#12381).
7610 This simplifies the code, and makes it a bit smaller and faster,
7611 and (most important) makes it easier to clean up signal handling
7612 since we can stop worring about floating-point exceptions in
7613 library code. That was a problem before C89, but the problem
7614 went away many years ago on all practical Emacs targets.
7615 * data.c, image.c, lread.c, print.c:
7616 Don't include <math.h>; no longer needed.
7617 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7618 might be autoconfigured, as that never happens.
7620 * doprnt.c (DBL_MAX_10_EXP):
7621 * print.c (DBL_DIG):
7622 Remove. C89 or later always defines these.
7623 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7624 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7625 (arith_error, domain_error, domain_error2):
7626 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7627 no longer needed -- we simply return what C returns. All uses removed.
7628 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7630 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7631 Remove. All uses expanded, as these macros are no longer used
7632 more than once and are now more trouble than they're worth.
7633 (Ftan): Use tan, not sin / cos.
7634 (Flogb): Assume C89 frexp.
7635 (fmod_float): Assume C89 fmod.
7636 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7637 (init_floatfns): Remove. All uses removed.
7639 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7641 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7642 compositeToPoint for OSX < 10.6 (Bug#12390).
7644 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7646 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7647 This produces more-accurate results.
7649 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7651 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7652 changes (Bug#12088).
7654 2012-09-08 Chong Yidong <cyd@gnu.org>
7656 * syntax.c (Fstring_to_syntax): Doc fix.
7658 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7660 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7661 in the internal border.
7662 (x_set_window_size): Remove static variables and their usage.
7663 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7664 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7665 Remove fringe/internal border adjustment (Bug#11052).
7666 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7667 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7668 (ns_fix_rect_ibw): Remove.
7669 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7670 (ns_dumpglyphs_box_or_relief): Ditto.
7671 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7673 (ns_dumpglyphs_image): Ditto.
7674 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7676 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7677 their usage. Add fringe_extended_p and its use as in other terms.
7678 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7679 scroll bar was removed.
7680 (updateFrameSize): New function.
7681 (windowDidResize): Move code to updateFrameSize and call it.
7683 * nsterm.h (EmacsView): Add updateFrameSize.
7685 2012-09-07 Chong Yidong <cyd@gnu.org>
7687 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7689 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7691 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7693 More signal-handler cleanup (Bug#12327).
7694 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7695 Problem introduced when merging patches. Noted by Eli Zaretskii in
7696 <http://bugs.gnu.org/12327#67>.
7697 * floatfns.c: Comment fix.
7698 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7699 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7700 and anyway the declaration is harmless even if SIGDANGER is not defined.
7701 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7702 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7703 source files not surprisingly expected syssignal.h to define, or
7704 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7705 Include <sys/ioctl.h>, for FIONREAD.
7706 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7707 This eliminates a problem whereby other files mysteriously had
7708 to include "syssignal.h" before including "systty.h" if they
7709 wanted to use "#ifdef SIGIO".
7711 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7713 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7715 * w32.c (sigemptyset): Empty the set.
7716 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7718 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7720 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7722 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7723 (mark_object): Likewise for frame objects.
7725 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7727 * syssignal.h (handle_on_main_thread): Always declare,
7728 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7729 This ports to platforms without HAVE_PTHREAD.
7731 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7733 Signal-handler cleanup (Bug#12327).
7734 Emacs's signal handlers were written in the old 4.2BSD style with
7735 sigblock and sigmask and so forth, and this led to some
7736 inefficiencies and confusion. Rewrite these to use
7737 pthread_sigmask etc. without copying signal sets around. Also,
7738 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7739 'signal', and instead use functions that do not attempt to take
7740 over the system name space. This patch causes Emacs's text
7741 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7742 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7743 Do not include <signal.h> or "syssignal.h", as these
7744 modules do not use signals.
7745 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7746 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7747 Do not include <signal.h>, as "syssignal.h" does that for us now.
7748 * atimer.c (sigmask_atimers): New function.
7749 (block_atimers, unblock_atimers): New functions,
7750 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7752 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7753 no longer needed here.
7754 * emacs.c (main): Inspect existing signal handler with sigaction,
7755 so that there's no need to block and unblock SIGHUP.
7756 * sysdep.c (struct save_signal): New member 'action', replacing
7757 old member 'handler'.
7758 (save_signal_handlers, restore_signal_handlers):
7759 Use sigaction instead of 'signal' to save and restore.
7760 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7761 New function. All users of 'signal' modified to use set_sighandler
7762 if they're writeonly, and to use sys_signal if they're read+write.
7763 (emacs_sigaction_init, forwarded_signal): New functions.
7764 (sys_signal): Remove. All uses replaced by calls to sigaction
7765 and emacs_sigaction_init, or by direct calls to 'signal'.
7766 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7767 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7768 all uses replaced by pthread_sigmask etc. calls.
7769 * syssignal.h: Include <signal.h>.
7770 (emacs_sigaction_init, forwarded_signal): New decls.
7771 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7772 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7773 (sigmask, sys_sigmask): Remove; no longer needed.
7774 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7775 (sigblock, sigunblock, sigfree):
7776 (sigsetmask) [!defined sigsetmask]:
7777 Remove. All uses replaced by pthread_sigmask.
7778 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7779 no longer need to be replaced, and its typical old uses
7780 are now done via emacs_sigaction_init and sigaction.
7781 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7782 (sys_sigdel): Remove; unused.
7783 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7785 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7787 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7788 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7790 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7792 Explicitly mark buffer_defaults and buffer_local_symbols.
7793 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7794 mark_local_symbols here.
7795 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7796 since special buffers aren't marked here any more.
7797 (allocate_buffer): Chain new buffer with all_buffers here...
7798 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7800 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7801 (syms_of_buffer): Remove staticpro of the above.
7802 (init_buffer_once): Set names for buffer_defaults and
7803 buffer_local_symbols.
7805 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7807 Use bool for booleans in font-related modules.
7808 * font.c (font_intern_prop, font_style_to_value)
7809 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7810 (generate_otf_features, font_check_otf_features, font_check_otf)
7811 (font_match_p, font_list_entities, font_at):
7812 * fontset.c (fontset_id_valid_p, reorder_font_vector
7813 (fontset_find_font, Fset_fontset_font)
7814 (face_suitable_for_char_p) [0]:
7815 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7816 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7817 (m17n_flt_initialized, ftfont_shape_by_flt):
7818 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7819 * nsfont.m (nsfont_draw):
7820 * w32font.c (w32font_draw):
7821 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7822 Use bool for booleans.
7823 * font.h: Adjust to above API changes.
7824 (struct font, struct font_driver, struct font_driver_list):
7825 Use bool for booleans.
7826 (struct font): Remove useless member encoding_type.
7828 * fontset.c, xftfont.c: Omit unnecessary static decls.
7830 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7832 * alloc.c (mark_object): Revert window marking code
7833 since it's unsafe for the Fset_window_configuration.
7835 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7837 Fix race conditions with signal handlers and errno (Bug#12327).
7838 Be more systematic about preserving errno whenever a signal
7839 handler returns, even if it's not in the main thread. Do this by
7840 renaming signal handlers to distinguish between signal delivery
7841 and signal handling. All uses changed.
7842 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7843 * data.c (deliver_arith_signal): Rename from arith_error.
7844 * dispnew.c (deliver_window_change_signal): Rename from
7845 window_change_signal.
7846 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7847 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7848 * keyboard.c (deliver_input_available_signal): Rename from
7849 input_available_signal.
7850 (deliver_user_signal): Rename from handle_user_signal.
7851 (deliver_interrupt_signal): Rename from interrupt_signal.
7852 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7853 (deliver_child_signal): Rename from sigchld_handler.
7854 * atimer.c (handle_alarm_signal):
7855 * data.c (handle_arith_signal):
7856 * dispnew.c (handle_window_change_signal):
7857 * emacs.c (handle_fatal_signal, handle_danger_signal):
7858 * keyboard.c (handle_input_available_signal):
7859 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7860 * process.c (handle_pipe_signal, handle_child_signal):
7861 New functions, with the actual signal-handling code taken from the
7862 original respective signal handlers, sans the sporadic attempts to
7863 preserve errno, since that's now done by handle_on_main_thread.
7864 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7865 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7866 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7868 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7869 Move initialization of main_thread to sysdep.c's init_signals.
7870 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7871 our usage, and simplifies the mainline code.
7872 (record_child_status_change): New static function, as a helper
7873 for handle_child_signal, and with most of the old child handler's
7875 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7876 (handle_child_signal): Use the above.
7877 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7878 Moved here from emacs.c.
7879 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7880 code moved here from emacs.c's main function.
7881 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7882 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7883 This lets callers save and restore errno properly.
7885 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7887 Remove redundant or unused things here and there.
7888 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7889 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7890 * editfns.c (Fcompare_buffer_substrings): Likewise.
7891 * frame.h (struct terminal, struct font_driver_list):
7892 Remove redundant declarations.
7893 * window.h (Qleft, Qright): Likewise.
7895 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7897 Do not mark objects from deleted buffers, windows and frames.
7898 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7899 (mark_object): Likewise for windows and frames.
7901 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7903 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7904 buffer_defaults and buffer_local_symbols as valid objects.
7905 Return special value to denote them.
7907 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7909 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7910 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7911 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7912 (file_name_absolute_p, Fsubstitute_in_file_name):
7913 (check_executable, check_writable, Ffile_accessible_directory_p)
7914 (Fset_file_selinux_context, Fdefault_file_modes)
7915 (Finsert_file_contents, choose_write_coding_system)
7916 (Fwrite_region, build_annotations, a_write, e_write)
7918 * filelock.c (boot_time_initialized, get_boot_time)
7919 (get_boot_time_1, lock_file_1, within_one_second):
7920 * floatfns.c (in_float):
7921 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7922 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7923 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7924 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7925 * window.c (compare_window_configurations):
7926 Use bool for booleans.
7927 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7928 (Fdefault_file_modes): Now mode_t, not int, for modes.
7929 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7930 (internal_delete_file): Now returns void, not a (boolean) int,
7931 since nobody was looking at the return value.
7932 * lisp.h, window.h: Adjust to above API changes.
7934 * xdisp.c (set_message): Simplify and reindent last change.
7936 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7938 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7940 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7942 * eval.c (call_debugger): Make the function non-static so that we
7943 can call it from set_message.
7945 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7946 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7948 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7950 Give more-useful info on a fatal error (Bug#12328).
7951 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7952 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7953 of doing the work ourselves.
7954 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7955 do most of the work.
7956 (fatal_error_backtrace): New function, taken from the guts
7957 of the old fatal_error_signal, but with a new option to output
7959 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7960 info about the signal than just its number.
7961 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7962 * sysdep.c: Include <execinfo.h>
7963 (emacs_backtrace): New function, taken partly from the previous
7964 code of the 'die' function.
7965 (emacs_abort): Call fatal_error_backtrace rather than abort.
7967 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7969 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7970 eager (load-time) macro-expansion.
7971 * lisp.mk (lisp): Add macroexp.
7973 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7975 Simplify redefinition of 'abort' (Bug#12316).
7976 Do not try to redefine the 'abort' function. Instead, redo
7977 the code so that it calls 'emacs_abort' rather than 'abort'.
7978 This removes the need for the NO_ABORT configure-time macro
7979 and makes it easier to change the abort code to do a backtrace.
7980 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7981 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7982 Remove; sysdep.c's emacs_abort now takes its place.
7983 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7984 'abort' changed to use 'emacs_abort'.
7985 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7986 (abort) [!defined abort]: Rename to ...
7987 (emacs_abort): ... new name.
7988 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7989 the place of the old 'abort' in emacs.c.
7990 * w32.c, w32fns.c (abort): Do not #undef.
7991 * w32.c (emacs_abort): Rename from w32_abort.
7993 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7995 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7996 offsets[j].dv, since the y axis of the screen coordinates points
7997 down, while the y axis of the font definition coordinates points
7998 up. This fixes display of Arabic diacritics such as KASRA and
7999 KASRATAN. (Bug#11860)
8001 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
8003 Be more systematic about _setjmp vs setjmp.
8004 * alloc.c (test_setjmp, mark_stack):
8005 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
8006 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
8007 (png_load, my_error_exit, jpeg_load):
8008 * process.c (send_process_trap, send_process):
8009 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
8010 The underscored versions are up to 30x faster on some hosts.
8011 Formerly, the code used setjmp+longjmp sometimes and
8012 _setjmp+_longjmp at other times, with no particular reason to
8013 prefer setjmp+longjmp.
8015 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
8017 Fix minor problem found by static checking.
8018 * buffer.c (Fdelete_all_overlays): Return nil.
8020 2012-09-03 Martin Rudalics <rudalics@gmx.at>
8022 * buffer.c (Fdelete_all_overlays): New function.
8024 2012-09-03 Chong Yidong <cyd@gnu.org>
8026 * gtkutil.c: Add extern decl for Qxft.
8028 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
8030 * emacs.c, eval.c: Use bool for boolean.
8031 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
8032 (malloc_using_checking) [DOUG_LEA_MALLOC]:
8033 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
8034 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
8035 (main, decode_env_path, Fdaemon_initialized):
8036 * eval.c (call_debugger, Finteractive_p, interactive_p):
8037 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
8038 (maybe_call_debugger, Fbacktrace):
8039 * process.c (read_process_output, exec_sentinel):
8040 Use bool for booleans.
8041 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
8042 All callers changed.
8043 * eval.c (interactive_p): Omit always-true boolean argument
8044 EXCLUDE_SUBRS_P. All callers changed.
8045 * dispextern.h, lisp.h: Reflect above API changes.
8046 * firstfile.c (dummy): Use the address of 'main', whose signature
8047 won't change, instead of the address of 'initialize', whose
8048 signature just changed from int to bool.
8049 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
8050 * msdos.c (fatal_error_in_progress): ... from here.
8051 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
8053 (redisplay_internal, unwind_redisplay): Simply clear
8054 REDISPLAYING_P when unwinding, instead of saving its previous,
8055 always-false value and then restoring it.
8057 Clean up some extern decls.
8058 Mostly, this hoists extern decls out of .c files and into .h files.
8059 That way, we're more likely to catch errors if the interfaces change.
8060 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
8061 declare xg_mark_data.
8062 * dispextern.h (x_frame_parm_handlers):
8064 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
8065 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
8066 (Qultra_bold, Qoblique, Qitalic):
8067 Move extern decl here from .c file.
8068 * alloc.c (xg_mark_data) [USE_GTK]:
8070 * eval.c (Qlexical_binding):
8071 * fns.c (time) [!HAVE_UNISTD_H]:

8077 * process.c (QCfamily, QCfilter):
8078 * widget.c (free_frame_faces):
8079 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
8080 * xfont.c (x_clear_errors):
8081 * xterm.c (x_frame_parm_handlers):
8082 Remove now-redundant extern decls.
8083 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
8084 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
8086 * xfaces.c: Remove unnecessary static decls.
8087 * xterm.c (updating_frame): Remove decl of nonexistent object.
8089 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
8090 when building globals.h, as the objects that are not built on
8091 this host are not needed to compile C files on this host.
8093 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
8095 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
8097 * frame.h: Add missing prototype for x_wm_set_size_hint.
8099 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

8103 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
8104 (Fsubstitute_command_keys):

8109 (make_buffer_string, make_buffer_string_both)
8110 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

8133 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
8135 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
8136 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

8141 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
8143 2012-09-01 Eli Zaretskii <eliz@gnu.org>
8145 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
8146 more than one grapheme cluster passed to the shaper: compute the
8147 offset adjustment values separately for each cluster. (Bug#11860)
8149 * image.c: Restore mistakenly removed inclusion of w32.h. Without
8150 it, GCC doesn't see prototypes of w32_delayed_load, and complains
8151 about implicit conversions from integer to pointer.
8153 2012-09-01 Daniel Colascione <dancol@dancol.org>
8155 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
8156 system used too early.
8158 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
8160 Better seed support for (random).
8161 * emacs.c (main): Call init_random.
8162 * fns.c (Frandom): Set the seed from a string argument, if given.
8163 Remove long-obsolete Gentzel cruft.

8165 (init_random): New function.
8167 2012-09-01 Daniel Colascione <dancol@dancol.org>
8169 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
8170 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
8171 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
8172 x_wm_set_size_hint, x_query_colors, x_real_positions,
8173 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
8174 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
8175 all of which have been moved to common code.
8177 * xfaces.c: Include TERM_HEADER instead of listing all possible
8178 window-system headers.
8180 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
8183 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
8184 directly accessing frame internals.
8186 * w32font.h: Include font.h. Define syms_of_w32font and
8189 * process.c: Include TERM_HEADER instead of listing all possible
8190 window-system headers.
8192 * nsterm.h: Remove declarations now in frame.h.
8193 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
8195 * menu.c: Include TERM_HEADER instead of listing all possible
8196 window-system headers.
8198 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
8201 * keyboard.c: Include TERM_HEADER instead of listing all possible
8202 window-system headers.
8204 * image.c: Include TERM_HEADER instead of listing all possible
8205 window-system headers. Declare Vlibrary_cache when compiling for
8208 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
8209 window system declarations.
8211 * frame.h: Move common functions here: set_frame_menubar,
8212 x_set_window_size, x_sync, x_get_focus_frame,
8213 x_set_mouse_position, x_set_mouse_pixel_position,
8214 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

8225 window-system headers.
8227 * emacs.c: Include TERM_HEADER.
8229 * dispnew.c: Include TERM_HEADER instead of listing all possible
8230 window-system headers.
8232 * ccl.h: Include character.h.
8234 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
8235 the current window system; include in list of objects to link into

8240 Remove mark_ttys function and fix tty_display_info initialization.
8241 * lisp.h (mark_ttys): Remove prototype.
8242 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8243 to mark_ttys because all possible values of 'top_frame' slot are
8244 the frames which are reachable from Vframe_list.
8245 * term.c (mark_ttys): Remove.
8246 (init_tty): Safely initialize 'top_frame' slot with Qnil.
8248 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8250 Change struct frame bitfields from unsigned char to unsigned.

8254 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
8255 bitfields from unsigned char to unsigned.

8259 Remove unused member of struct x_output and struct w32_output.
8260 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
8261 * w32term.h (struct w32_output): Likewise.
8263 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
8265 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
8266 does not become zero (Bug#12234).
8268 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
8270 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
8271 for GCC 4.7.1 x86-64.
8273 2012-08-30 Glenn Morris <rgm@gnu.org>
8275 * lread.c (init_lread): For out-of-tree builds, only add the
8276 source directory's site-lisp dir to the load-path if it exists,
8277 consistent with in-tree builds. (Bug#12302)
8279 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
8281 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
8282 button_values to NULL. Call setStykeMask so dialogs get a close button.
8283 (windowShouldClose:): Set window_closed.
8284 (dealloc): New member, free button_values.
8285 (process_dialog:): Make member function. Remove window argument,

8294 (initFromContents:isQuestion:): Adjust call to process_dialog.
8295 Code formatting change.
8296 (timeout_handler:): Set timer_fired to YES.
8297 (runDialogAt:): Set timer_fired to NO.
8298 Handle click on close button as quit.
8300 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8301 Add window_closed and button_values. Add void as return value for
8302 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8303 Add process_dialog as new member.
8305 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8307 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
8308 is not one of the heaps we manage. (Bug#12242)
8310 2012-08-28 Glenn Morris <rgm@gnu.org>
8312 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

8324 if the buffer is dead.
8325 (Fother_buffer, other_buffer_safely): Remove redundant
8328 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
8330 Always use set_buffer_if_live to restore original buffer at unwind.

8368 (change_frame_size_1, sit_for):
8369 Use bool for boolean.
8370 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
8371 and remove last int (actually boolean) argument, which was always 0.
8372 All callers changed.
8373 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
8374 * dispextern.h (struct composition_it): Use bool for boolean.
8375 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
8376 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
8377 * dired.c (file_name_completion):
8378 Use bool for boolean. (This was missed in an earlier change.)
8380 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8382 * window.c (Fset_window_configuration): Revert first part of
8385 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
8387 * nsterm.h (NSPanel): New class variable dialog_return.
8389 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
8390 Initialize dialog_return.
8391 (windowShouldClose:): Use stop instead of stopModalWithCode.
8392 (clicked:): Ditto, and also set dialog_return (Bug#12258).
8393 (timeout_handler:): Use stop instead of abortModal. Send a dummy
8395 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

8410 Use bool for booleans.
8411 * dired.c (file_name_completion):
8412 * process.h (fd_callback):
8413 Omit int (actually boolean) argument. It wasn't being used.

8440 Use bool for booleans.
8441 * coding.h, lisp.h: Reflect above API changes.
8442 * coding.c: Remove unnecessary static function decls.
8443 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8444 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8445 not a boolean 'int', since callers never look at the return value.
8446 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8447 * coding.h (decoding_buffer_size, encoding_buffer_size)
8448 (emacs_mule_string_char): Remove unused extern decls.
8449 (struct iso_2022_spec, struct coding_system):

8455 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8457 Fix spare memory change (Bug#12286).
8458 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8459 (valid_lisp_object_p): Likewise.
8461 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8463 * window.c (Fset_window_configuration): Record any window's old
8464 buffer if it's replaced (see Bug#8789). If the new current
8465 buffer doesn't appear in the selected window, go to its old
8468 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8470 Special MEM_TYPE_SPARE to denote reserved memory.
8471 * alloc.c (enum mem_type): New memory type.
8472 (refill_memory_reserve): Use new type for spare memory.
8473 This prevents live_cons_p and live_string_p from incorrect
8474 detection of uninitialized objects from spare memory as live.
8476 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8479 * Makefile.in (.PHONY): versioclean -> versionclean.
8481 Remove unused external symbols.
8482 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8483 * window.c (Qwindow_valid_p, decode_valid_window):
8484 Now static, not extern.
8485 * data.c (Qinterval): Remove; unused.
8486 (syms_of_data): Do not define 'interval'.
8487 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8488 * window.h (decode_valid_window):
8491 * character.c, charset.c, chartab.c: Use bool for booleans.

8501 (char_table_set_range, optimize_sub_char_table)
8502 (map_sub_char_table):
8503 Use bool for boolean.
8504 * character.c (str_to_unibyte): Omit last boolean argument; it was
8505 always 0. All callers changed.
8506 * character.h, charset.h: Adjust to match previous changes.
8507 * character.h (char_printable_p): Remove decl of nonexistent function.
8508 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8509 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8510 are all boolean, so make them single-bit bitfields.
8512 * lisp.h (ASET): Remove attempt to detect side effects.
8513 It was meant to be temporary and it often doesn't work,
8514 because when IDX has side effects the behavior of IDX==IDX
8515 is undefined. See Stefan Monnier in
8516 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8518 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8520 * lisp.h (functionp): New function (extracted from Ffunctionp).
8521 (FUNCTIONP): Use it.
8522 * eval.c (Ffunctionp): Use it.
8524 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8526 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8527 as that's faster and simpler than static storage. Don't bother
8528 with the g_main_context_query overhead if g_main_context_pending
8529 says no events are pending.
8530 (gfds, gfds_size): Remove these static vars.
8531 (xgselect_initialize): Remove; no longer needed.
8532 All uses and decls removed.
8534 * emacs.c (fatal_error_signal_hook): Remove.
8535 All uses removed. This leftover from old code was always 0.
8537 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8538 * casefiddle.c (casify_object, casify_region):
8539 * casetab.c (set_case_table):
8540 * category.c, category.h (word_boundary_p):
8541 * category.h (CHAR_HAS_CATEGORY):
8542 Use bool for booleans, instead of int.
8544 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8546 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8548 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8550 On assertion failure, print backtrace if available.
8551 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8552 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8553 * Makefile.in (LIB_EXECINFO): New macro.
8556 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8557 * bytecode.c (exec_byte_code):
8558 * callint.c (check_mark, Fcall_interactively):
8559 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8560 (getenv_internal, sync_process_alive, call_process_exited):
8561 * lisp.h (USE_SAFE_ALLOCA):
8562 Use bool for booleans, instead of int.
8563 * lisp.h, process.h: Adjust prototypes to match above changes.
8564 * callint.c (Fcall_interactively): Don't assume the mark's
8565 offset fits in 'int'.
8567 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8569 * buffer.c, buffer.h: Use bool for boolean.

8576 (mmap_enlarge, mmap_set_vars):
8577 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8578 Use bool for booleans, instead of int.
8579 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8580 since the 1-or-0 return value is always ignored anyway.
8581 (mmap_initialized_p):
8582 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8583 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8585 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8587 * bidi.c: Use bool for boolean.
8588 This is a bit more readable, and makes the text segment of bidi.o
8589 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8590 Presumably it's faster too.
8591 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

8599 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8600 (bidi_unshelve_cache): Adjust decls to match code.

8614 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8615 compile time tests instead of run time tests on systems that do
8617 (FRAME_MAC_P): Remove leftover from deleted code.
8618 * frame.c (syms_of_frame): Remove leftover from deleted code.
8620 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8622 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8624 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8626 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8627 Otherwise, the compiler complains about (A?B:C) where B is void
8628 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8629 (fontset_add): Return void, for FONTSET_ADD.
8631 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8633 * alloc.c: Use bool for booleans.
8634 (gc_in_progress, abort_on_gc)

8641 (mark_stack, valid_pointer_p, make_pure_string)
8642 (Fgarbage_collect, survives_gc_p, gc_sweep):
8643 Use bool for booleans, instead of int.
8644 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8645 Remove unused local.
8646 * alloc.c (PURE_POINTER_P):
8647 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.

8655 * print.c (Fprin1_to_string):
8656 * xdisp.c (push_message):
8657 Use bool for booleans affected directly or indirectly by
8660 Make recently-introduced setters macros.

8662 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8663 (set_fontset_default, set_fontset_fallback): Rename from their
8664 upper-case counterparts, and make them functions rather than macros.
8665 This is more consistent with the other recently-introduced setters.
8666 These don't need to be inline, since they're local.

8673 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8675 * lisp.h (vcopy): Use memcpy rather than our own loop.
8676 This fixes a performance regression introduced by the recent
8677 addition of vcopy. This means 'vcopy' will need to be modified
8678 for a copying collector, but that's OK. Also, tighten the
8679 checking in the assertion.
8681 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8683 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8684 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8685 non-base glyph for the width of the base character, according to
8686 what x_draw_composite_glyph_string_foreground expects.
8687 Generate WADJUST value according to composition_gstring_width's
8688 expectations, to produce correct width of the composed character.
8689 Reverse the sign of the DU offset produced by ScriptPlace.
8691 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8693 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

8721 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8724 2012-08-20 Glenn Morris <rgm@gnu.org>
8726 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8727 Don't assume that `ln -f' works.
8729 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8731 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8732 and later about non-assignments with no effect. See discussion at
8733 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for

8757 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8758 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8759 (set_hash_key_and_value, set_hash_index, set_hash_next)
8760 (set_hash_hash): New functions.
8761 * charset.c, fns.c: Adjust users.
8763 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>

8773 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8775 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8777 Rely on <config.h> + <unistd.h> to declare 'environ',
8778 as gnulib does this if the system doesn't.
8779 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8780 Remove declaration. MS-Windows declares it on stdlib.h which is
8781 included by conf_post.h.
8782 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8783 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8784 * vm-limit.c: Include <unistd.h>, for 'environ'.
8786 * unexaix.c, unexcoff.c: Include "mem-limits.h".

8789 * xdisp.c (handle_invisible_prop): Make it a bit faster
8790 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8792 2012-08-19 Chong Yidong <cyd@gnu.org>

8803 (Fkill_local_variable): Likewise.
8805 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8807 * nsfont.m (ns_ascii_average_width): Ensure the string
8808 ascii_printable is initialized with a null-terminated character
8809 array. Otherwise, it can contain undesired extra characters.

8813 port new setting code to Sun C 5.8 2005/10/13
8814 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8815 Return void, not Lisp_Object. Otherwise, the compiler
8816 complains about (A?B:C) where B is void and C is Lisp_Object
8817 when compiling CHAR_TABLE_SET, due to the recent change to
8818 the API of sub_char_table_set_contents.
8820 2012-08-18 Chong Yidong <cyd@gnu.org>
8822 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

9650 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
9651 * w32.c (init_environment): Change the default values of many
9652 environment variables in dflt_envvars[] to NULL, to avoid pushing
9653 them into environment when they were not already defined.
9654 Remove the code that deletes site-lisp subdirectories from the default
9655 value of EMACSLOADPATH, as it is no longer needed.
9656 (check_windows_init_file): Now external, not static.
9657 Use Vload_path as is, without adding anything, as this function is now
9658 called when Vload_path is already set up.
9660 * w32.h (check_windows_init_file): Add prototype.
9662 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
9663 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
9664 compatibility with Posix platforms.
9665 (main): Move the call to check_windows_init_file to here from
9667 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
9668 any, in the DEFALT argument into the root of the Emacs build or
9669 installation tree, as appropriate.
9671 * callproc.c (init_callproc_1): Call decode_env_path instead of
9672 doing its equivalent by hand.
9673 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
9674 the code that sets Vexec_path run on MS-Windows.
9676 * lread.c (init_lread): Add comments to #ifdef's.
9678 * msdos.c (dos_set_window_size, IT_update_begin)

9690 Remove unnecessary casts involving pointers.
9691 These casts are no longer needed now that we assume C89 or later,

9705 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9706 Remove unnecessary pointer casts.
9707 * alloc.c (record_xmalloc): New function.
9708 * lisp.h (record_xmalloc): New decl.
9709 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9710 more like a function. This is because the pointer cast is not
9711 needed. All uses changed.
9712 * print.c (print_string, print_error_message): Avoid length recalc.
9714 Improve fix for macroexp crash with debugging (Bug#12118).
9715 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9716 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9717 not supposed to be invoked from the garbage collector.
9718 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9719 (gc_aset): New function, which is like ASET but can be
9720 used in the garbage collector.

9736 headers (most versions of MinGW w32api don't).
9737 (get_security_info, create_symbolic_link)
9738 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

9749 with addition of handling of symlinks and support for 'lstat'.
9750 If possible, get file's attributes and security information by
9751 handle, not by name. Produce S_IFLNK bit for symlinks, when
9752 called from 'lstat'.
9753 (stat, lstat): New functions, call 'stat_worker'.
9754 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9755 symlinks when the underlying filesystem supports them.
9757 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9759 Fix macroexp crash on Windows with debugging (Bug#12118).
9760 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9761 checking subscripts; problem introduced with the recent
9762 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9763 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9764 since it's used in non-static inline functions now.
9766 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9767 Don't assume buffer size fits in 'int'. Remove unused local.

9785 * character.c (CHARACTER_INLINE):
9786 * charset.c (CHARSET_INLINE):
9787 * composite.c (COMPOSITE_INLINE):
9788 * dispnew.c (DISPEXTERN_INLINE):
9789 * sysdep.c (SYSTIME_INLINE):
9790 Define to EXTERN_INLINE, so that the corresponding functions
9791 are compiled into code.
9792 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9793 (INLINE_HEADER_END): New macros.
9794 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9816 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9818 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9819 This how ASET and AREF are supposed to work, and makes
9820 it easier to think about future improvements. See
9821 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9822 * charset.h (set_charset_attr): New function.

10200 (w32_read_console_input): New inline function, calls either
10201 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
10202 w32_console_unicode_input.
10203 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
10204 (w32_kbd_patch_key, key_event): Use the codepage returned by

10221 Adjust GDB to reflect pvec_type changes (Bug#12036).
10222 * .gdbinit (xvectype, xpr, xbacktrace): Adjust to reflect the
10223 2012-07-04 changes to pseudovector representation.
10224 Problem reported by Eli Zaretskii in <http://bugs.gnu.org/12036#30>.

10237 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10238 enumeration constants, as PURE and HEAP are too general, and clash
10239 with other headers and sources, such as gmalloc.c and the
10240 MS-Windows system headers. All users changed.
10242 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10244 Revert last save_excursion_save and save_excursion_restore changes.
10245 * alloc.c, editfns.c, marker.c, lisp.h: Revert.
10246 Lots of crashes reported by Chong Yidong <cyd@gnu.org>.
10248 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10250 Fix recently-introduced typos in Windows port.
10251 Reported by Martin Rudalics <rudalics@gmx.at>.

10253 * w32fns.c (syms_of_w32fns): Add missing parenthesis.
10255 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10257 Improve GDB symbol export (Bug#12036).
10258 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10259 arms of an 'if', not using conditional expressions; otherwise GDB
10260 complains about the types in the unevaluated arm when the argument
10261 is an integer literal.
10262 (xgetint): Simplify expression.
10263 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10264 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10265 Zaretskii in <http://bugs.gnu.org/12036#13>.
10266 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10267 needed now that we have gdb_make_enums_visible.
10268 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10269 (enum enum_USE_LSB_TAG):
10270 New enum types, packaging up enums that need to be exported to GDB.
10272 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10274 Utility function to make a list from specified amount of objects.
10275 * lisp.h (enum constype): New datatype.
10276 (listn): New prototype.
10277 * alloc.c (listn): New function.
10278 (Fmemory_use_count, syms_of_alloc): Use it.

10293 Fast save_excursion_save and save_excursion_restore.
10294 * lisp.h (struct Lisp_Excursion): New data type.
10295 (PVEC_EXCURSION): New pseudovector type.
10296 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10297 to deal with it. Adjust comments.
10298 (init_marker, attach_marker): New prototype.
10299 (unchain_marker): Adjust prototype.
10300 * marker.c (attach_marker): Change to global.
10301 (init_marker): New function.

10303 (build_marker): More easserts.
10304 (mark_object): Handle struct Lisp_Excursion.
10305 * editfns.c (save_excursion_save, save_excursion_restore):

10311 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10312 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10313 emacs.c, as this is a more-suitable home. Had this been done earlier
10314 the fix for 12036 would have avoided some of the problems noted in
10315 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10316 would have been more obvious.
10317 * emacs.c: Do not include <verify.h>; no longer needed.
10318 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
10319 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
10320 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10321 Remove; now done in lisp.h.
10322 * lisp.h (PUBLISH_TO_GDB): New macro.
10323 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
10324 (DATA_SEG_BITS): Use it.
10325 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10326 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10327 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10328 not be usable in #if. This simplifies things.
10330 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10332 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10334 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10336 Simplify export of symbols to GDB (Bug#12036).
10337 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10338 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10339 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10340 Adjust to changes in lisp.h and emacs.c, by using
10341 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10342 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10343 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10344 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10345 instead of gdb_valbits.
10346 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10347 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10348 instead of gdb_array_mark_flag.
10349 (xboolvector): Get size from $->size, not $->header.size.
10350 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10351 (xreload, hook-run, hookpost-run): Remove.
10352 * emacs.c: Include <verify.h>.
10353 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10354 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10356 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10357 (gdb_USE_LSB_TAG): New enum constants.
10358 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10359 Also define these as enum constants, so they're visible to GDB.
10360 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10361 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10362 as constants, so they're visible to GDB.
10363 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10364 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10365 Now enum constants, not macros, so they're visible to GDB.
10366 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10367 more convenient now. All uses changed.
10368 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10369 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10371 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
10373 Explicitly free restriction data that are not needed anymore.
10374 * editfns.c (save_restriction_restore): Free restriction data.
10376 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
10378 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10379 add argument, tune behavior, and adjust all callers.
10381 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10383 Use typedef for EMACS_INT, EMACS_UINT.
10384 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10385 than macros. This simplifies debugging in the usual case, since
10386 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10387 and it allows expressions involving EMACS_INT casts.
10388 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10390 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10392 * nsterm.m (ns_read_socket): Return early if there is a modal
10393 window (Bug#12043).
10395 2012-07-25 Martin Rudalics <rudalics@gmx.at>
10397 * frame.c (Fredirect_frame_focus): In doc-string don't mention
10398 that FOCUS-FRAME can be omitted.

11245 (menu_separator_name_p):
11246 * nsmenu.m (ns_update_menubar):
11247 Prefer memcmp to strncmp when either will do.
11248 * nsterm.m: Include <ftoastr.h>.
11250 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11251 Prefer snprintf to strncpy.
11252 * nsterm.m (ns_term_init):
11253 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11254 * nsterm.m (ns_term_init):
11255 Avoid the need for strncpy, by using build_string or
11256 make_unibyte_string directly. Use dtoastr, not snprintf.
11257 * process.c (Fmake_network_process): Diagnose service names that
11258 are too long, rather than silently truncating them or creating
11259 non-null-terminated names.

11274 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
11275 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
11276 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
11277 where argument type is known to be a Lisp_Cons.
11279 2012-07-10 Tom Tromey <tromey@redhat.com>
11281 * bytecode.c (BYTE_CODE_THREADED): New macro.

11291 (build_pure_c_string): New function, defined as static inline. This
11292 provides a better opportunity to optimize away calls to strlen when
11293 the function is called with compile-time constant argument.
11294 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11295 argument, adjust users accordingly. Use build_pure_c_string where
11297 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
11298 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11299 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
11301 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
11303 Avoid calls to strlen in miscellaneous functions.
11304 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
11305 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
11306 * lread.c (openp): Likewise.
11308 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
11310 Avoid calls to strlen in path processing functions.
11311 * fileio.c (file_name_as_directory): Add comment. Change to add
11312 srclen argument and return the length of result. Adjust users
11314 (directory_file_name): Fix comment. Change to add srclen argument,
11315 swap 1st and 2nd arguments to obey the common convention.
11316 Adjust users accordingly.
11317 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
11319 2012-07-10 Glenn Morris <rgm@gnu.org>

11322 Move PENDING_OUTPUT_COUNT definition to configure.
11324 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):

11326 * s/gnu.h (DATA_START): Move definitions to configure.
11328 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
11329 We include usg5-4-common.h, which defines them both.
11331 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11332 O_RDONLY already includes it).
11334 Stop ns builds setting the EMACSLOADPATH environment variable.
11335 * nsterm.m (ns_load_path): Rename from ns_init_paths.
11336 Now it does not set EMACSLOADPATH, just returns the load-path string.
11337 * nsterm.h: Update accordingly.
11338 * lread.c [HAVE_NS]: Include nsterm.h.
11339 (init_lread) [HAVE_NS]: Use ns_load_path.
11340 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
11342 2012-07-09 Glenn Morris <rgm@gnu.org>
11344 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
11345 since the included bsd-common.h does so.
11347 Stop ns builds setting the EMACSPATH environment variable.
11348 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
11349 (ns_init_paths): Do not set EMACSPATH.
11350 * nsterm.h (ns_exec_path): Add it.
11351 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
11354 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
11356 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
11358 * process.c (wait_reading_process_output): 'waitchannels' was unset
11359 when read_kbd || !NILP (wait_for_cell); fix this.
11361 Add GCC-style 'const' attribute to functions that can use it.
11362 * character.h (char_resolve_modifier_mask):
11363 * keyboard.h (make_ctrl_char):
11364 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
11365 (init_character_once, next_almost_prime, init_fns, init_image)
11366 (flush_pending_output, init_sound):

11375 Minor improvements to make_formatted_string.
11376 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
11377 where int is good enough, as vsprintf returns an int.
11378 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
11380 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11382 Use make_formatted_string to avoid double length calculation.
11383 * lisp.h (make_formatted_string): New prototype.

11405 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
11407 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11409 Move marker debugging code under MARKER_DEBUG.
11410 * marker.c (MARKER_DEBUG): Move marker debugging code under
11411 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11412 for bootstrap with --enable-checking (~3x slowdown reported
11413 by Juanma Barranquero <lekktu@gmail.com>).
11414 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
11416 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
11418 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
11419 See <http://bugs.gnu.org/11825#29>.
11421 2012-07-08 Eli Zaretskii <eliz@gnu.org>
11423 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11424 has no font, use the frame's font. (Bug#11813)
11425 (display_line): Add commentary about displaying truncation glyphs
11427 (produce_special_glyphs): Move here from term.c.
11429 * term.c (produce_special_glyphs): Move to xdisp.c.
11431 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11434 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11436 * xdisp.c (display_line): Avoid warning about implicit declaration
11439 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11441 * lisp.h: Remove empty conditional.
11443 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11445 * lread.c (load_path_check): Now static.
11447 Fix some minor --with-ns problems found by static checking.
11448 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11449 (x_set_font) [!HAVE_X_WINDOWS]:
11450 * image.c (xpm_load_image) [HAVE_NS]:
11451 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11452 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11453 Remove unused local.
11454 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11455 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11456 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11457 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11458 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11459 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11460 Fix pointer signedness problem.
11461 * xfaces.c (FRAME_X_FONT_TABLE):
11462 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11464 2012-07-07 Glenn Morris <rgm@gnu.org>
11466 * lread.c (load_path_check): New function, split from init_lread.
11467 (init_lread): Reorganize. Motivation:
11468 If EMACSLOADPATH is set, check/warn about that rather than the
11469 defaults, which we are not going to use. Hence we can remove
11470 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11471 Don't warn if site-lisp directories are missing.
11472 If not installed, start from a blank load-path, since
11473 PATH_LOADSEARCH refers to the eventual installation directories.
11475 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11477 Support truncation and continuation glyphs on GUI frames, when
11478 fringes are disabled. (Bug#11832)
11479 * xdisp.c (init_iterator): Get dimensions of truncation and
11480 continuation glyphs even if on GUI frames.
11481 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11482 or both, are absent.
11483 (start_display, move_it_in_display_line_to): Handle the case of a
11484 GUI frame without a fringe to display continuation or truncation
11486 (insert_left_trunc_glyphs): Support GUI frames: make sure
11487 truncation glyphs overwrite enough glyphs from the current line to
11488 have sufficient space in pixels.
11489 (display_line): Support truncation and continuation glyphs on GUI
11490 frames. If some spare pixels are left on the line after inserting
11491 the truncation glyphs, fill that space with a stretch glyph of a
11492 suitably computed width.
11494 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11495 produce_glyphs, to support GUI sessions.
11497 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11499 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11501 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11503 Do not require float-time's arg to fit in time_t (Bug#11825).
11504 This works better on hosts where time_t is unsigned, and where
11505 float-time is applied to the (negative) difference between two times.
11506 * editfns.c (decode_time_components): Last arg is now double *,
11507 not int *, and means to store all the result as a double, without
11508 worrying about whether the seconds part fits in time_t.
11509 All callers changed.
11510 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11511 All callers changed.
11512 (Ffloat_time): Do not fail merely because the specified time falls
11513 outside of time_t range.
11515 2012-07-07 Glenn Morris <rgm@gnu.org>
11517 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11518 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11519 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11521 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11523 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11524 Update dependencies.
11526 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
11528 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

11532 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11533 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11534 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11535 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11537 * xfont.c (compare_font_names): Redo to omit the need for casts.
11539 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11541 * xfns.c (Fx_change_window_property): Doc fix.
11542 * w32fns.c (Fx_change_window_property): Doc fix.
11544 * w32fns.c (Fx_window_property): Accept the same arguments as the
11545 X Windows version. Doc fix.
11546 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11548 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11549 Eli Zaretskii <eliz@gnu.org>
11551 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11552 Windows-specific code from nt/config.nt moved here.
11553 Obsolete settings removed.
11555 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11557 * process.c: Avoid unnecessary calls to gettime.
11558 (wait_reading_process_output): Don't get the time of day
11559 when gobbling data immediately and not waiting, as there's no need
11560 for it in that case. This removes a FIXME.
11562 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11564 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11565 is defined (Bug#11768).
11567 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11569 Fix marker debugging code.
11570 * marker.c (byte_char_debug_check): Do not perform the check
11571 if buffer is not multibyte.
11572 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11573 Call byte_char_debug_check with correct arguments.
11575 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11577 Compile marker debugging code only if ENABLE_CHECKING is defined.
11578 * marker.c (byte_char_debug_check, count_markers):
11579 Use only if ENABLE_CHECKING is defined.
11580 (byte_debug_flag): Remove.
11581 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11582 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11584 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11586 Avoid code repetition in marker-related functions.
11587 * marker.c (attach_marker): New function.
11588 (Fset_marker, set_marker_restricted, set_marker_both)
11589 (set_marker_restricted_both): Use it.

11591 Consistently rename charno to charpos.
11592 (marker_position): Add eassert.
11593 (marker_byte_position): Convert to eassert.
11595 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11597 Simplify list operations in unchain_overlay and unchain_marker.

11607 * composite.c (autocmp_chars): Likewise.
11608 * editfns.c (buildmark): Remove.
11609 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11610 (save_restriction_save): Use build_marker.
11611 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11612 * window.c (save_window_save): Likewise.
11614 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11616 Do not use Fdelete_overlay in delete_all_overlays
11617 to avoid redundant calls to unchain_overlay.

11619 (delete_all_overlays, Fdelete_overlay): Use it.
11620 * minibuf.c (get_minibuffer): Fix comment.
11622 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11624 Port to OpenBSD 5.1 amd64.
11625 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11626 This is needed for OpenBSD, and should be harmless on all BSD systems.
11627 Also, include <sys/sysctl.h>, as it should be available on all
11628 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11629 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11630 use p_pid member, not kp_proc.pid.
11632 2012-07-06 Glenn Morris <rgm@gnu.org>
11634 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11636 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11638 More xmalloc and related cleanup.
11639 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
11640 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

11647 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11649 Omit needless casts involving void * pointers and allocation.
11650 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11651 as the former is more robust if P's type is changed.
11652 Prefer xzalloc to xmalloc + memset 0.
11653 Simplify malloc-or-realloc to realloc.
11654 Don't worry about xmalloc returning a null pointer.
11655 Prefer xstrdup to xmalloc + strcpy.
11656 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11658 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11659 alloca of a constant.

11663 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11664 hscroll is larger than the line width. Fixes long and futile
11665 looping inside extend_face_to_end_of_line (on a TTY) producing
11666 glyphs that are not needed and thrown away.
11668 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11670 * marker.c (set_marker_restricted_both): Simplify by using
11673 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11675 * editfns.c (region_limit): Simplify by using clip_to_bounds.

11684 followed by gtk_box_set_homogeneous (Bug#11768).
11685 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11686 (update_theme_scrollbar_width, xg_create_scroll_bar):
11687 Use gtk_scrollbar_new (Bug#11768).
11688 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11689 (is_box_type): New function (Bug#11768).
11690 (xg_tool_item_stale_p): Call is_box_type.
11691 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11692 with default display (Bug#11768).
11694 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11696 * xdisp.c (window_hscroll_limited): New function.
11697 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11698 coordinates when window's hscroll is set to insanely large
11699 values. (Bug#11857)
11701 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11764 * fileio.c (time_error_value): Check the right error number.
11765 Problem reported by Troels Nielsen in
11766 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11768 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11770 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11771 This should be fixed in a better way; see Eli Zaretskii in
11772 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11773 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11775 * fileio.c (time_error_value): Rename from special_mtime.
11776 The old name's problems were noted by Eli Zaretskii in
11777 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11779 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11780 This variable's comment says Emacs needs at least one GDB-visible
11781 symbol of type enum pvec_type, to work around GDB problems.
11782 The symbol's value doesn't matter.
11784 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11785 that causes compilation to fail on pre-C99 compilers.
11787 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11789 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

11792 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11794 * buffer.c (init_buffer_once): Fix initialization of
11795 headers for buffer_defaults and buffer_local_symbols.
11796 Reported by Juanma Barranquero <lekktu@gmail.com>.
11798 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11800 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11801 * lisp.h (enum pvec_type): Use fewer bits.
11802 (PSEUDOVECTOR_SIZE_BITS): New constant.
11803 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11804 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11805 change in pvec_type.
11806 (PSEUDOVECTOR_TYPEP): New macro.
11807 (TYPED_PSEUDOVECTORP): Use it.
11808 * fns.c (internal_equal): Adapt code to extract pvectype.
11809 * emacs.c (gdb_pvec_type): Update type.
11810 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11811 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11812 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11813 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11814 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11815 abusing vector->header.next.nbytes.
11816 (live_vector_p): Use PVEC_TYPE.
11817 (mark_object): Adapt code to extract pvectype. Use switch.
11819 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11821 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11822 Tighten new eassert a bit.
11824 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11826 Fix compilation with --enable-gcc-warnings and -O1
11827 optimization level.
11828 * doprnt.c (doprnt): Change type of tem to int, initialize
11829 to avoid compiler warning. Add eassert.
11830 * search.c (simple_search): Initialize match_byte to avoid
11831 compiler warning. Add eassert.
11833 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11835 Avoid weird behavior with large horizontal scrolls.
11836 Without this change, for example, large hscroll values would
11837 mess up Emacs's display on Fedora 15 x86, presumably due to
11838 overflows in int calculations in the display code.
11839 Also, if buffers had long lines, Emacs would freeze.
11840 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11841 (set_window_hscroll): New function, containing the old guts of
11842 Fset_window_hscroll. Return the clipped value.
11843 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11844 This avoids the need to check against PTRDIFF_MAX.
11846 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11848 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11850 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11852 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11854 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11855 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11856 since GCC 4.4.6 issues a bogus warning for them.
11858 Fix bugs in file timestamp newness comparisons.
11859 * fileio.c (Ffile_newer_than_file_p):
11860 * lread.c (Fload): Use full timestamp resolution of files,
11861 not just the 1-second resolution, so that files that are only
11862 slightly newer still count as newer.
11863 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11864 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11866 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11868 * fileio.c: Improve handling of file time marker. (Bug#11852)
11869 (special_mtime): New function.
11870 (Finsert_file_contents, Fverify_visited_file_modtime):
11871 Use it to set special mtime values consistently.
11873 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11875 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11876 marker for non-existing file. (Bug#11852)
11878 2012-07-03 Glenn Morris <rgm@gnu.org>
11880 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11881 and did not make it into globals.h).
11883 2012-07-03 Tom Tromey <tromey@redhat.com>
11885 * window.c (Fset_window_margins, Fset_window_fringes)
11886 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11887 * textprop.c (Fprevious_property_change): No longer static.

11921 2012-07-03 Glenn Morris <rgm@gnu.org>
11923 * lisp.h (Frandom): Make it visible to C.
11924 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11925 buffer for invisible buffers. (Bug#1229)
11927 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11929 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11930 values which aren't power of 2.
11931 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11932 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11935 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11937 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11939 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11941 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11943 * alloc.c (allocate_vector_block): Remove redundant
11944 calls to mallopt if DOUG_LEA_MALLOC is defined.
11945 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11946 avoid calls to mallopt if zero_vector is returned.
11948 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11950 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11951 is enabled, avoid dereferencing NULL current_sblock if
11954 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11956 Cleanup basic buffer management.
11957 * buffer.h (struct buffer): Change layout to use generic vector
11958 marking code. Fix some comments. Change type of 'clip_changed'
11959 to bitfield. Remove unused #ifndef old.
11960 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11961 (GET_OVERLAYS_AT): Fix indentation.
11962 (for_each_per_buffer_object_at): New macro.
11963 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

11967 struct buffer. Fix comment.
11968 (mark_overlay): New function.
11969 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11970 Lisp area of struct buffer.
11971 (mark_object): Use it. Adjust marking of misc objects
11972 and related comments.
11974 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11976 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11977 wrapper that is not needed because the wrapped code is a no-op (zero
11978 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11979 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11981 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11983 * alloc.c (mark_buffer): Simplify. Remove prototype.
11984 (mark_object): Add comment. Reorganize marking of vector-like
11985 objects. Use CHECK_LIVE for all vector-like objects except buffers
11986 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11987 Avoid redundant calls to mark_vectorlike for bool vectors.
11989 2012-06-30 Glenn Morris <rgm@gnu.org>
11991 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11993 * epaths.in (PATH_SITELOADSEARCH): New.
11994 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11995 This is rather than relying on --enable-locallisppath elements
11996 having "site-lisp" in their names. (Bug#10208#25, 11658)
11998 2012-06-30 Eli Zaretskii <eliz@gnu.org>
12000 * w32proc.c (sys_select): Accept and ignore one more argument.
12002 * w32.c (emacs_gnutls_pull): Call select with one more argument.
12004 * sysselect.h [DOS_NT]: Don't include sys/select.h.
12005 (pselect) [!MS_DOS]: Redirect to sys_select.
12007 * sysdep.c: Don't include dos.h and dosfns.h.
12009 * process.c (sys_select):
12010 * msdos.c (sys_select): Accept one more argument and ignore it.
12012 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
12013 adapt data types and code to that.
12016 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
12017 which clashes with the gnulib function of the same name.
12019 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
12021 * font.c (font_style_to_value, font_style_symbolic)
12022 (font_prop_validate_style): Add type checks for values in
12025 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
12027 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
12030 2012-06-29 Eli Zaretskii <eliz@gnu.org>
12032 * xdisp.c (try_window_id): Undo last change.
12034 * w32.c (getwd): Adjust commentary about startup_dir.
12035 (init_environment): Always call sys_access, even in non-MSVC
12036 builds. Don't chdir to the directory of the Emacs executable.
12037 This undoes code from 1997 which was justified by the need to
12038 "avoid conflicts when removing and renaming directories". But its
12039 downside was that every relative file name was being interpreted
12040 relative to the directory of the Emacs executable, which can never
12041 be TRT. In particular, it broke sys_access when called with
12042 relative file names.
12043 (sys_access): Map GetLastError to errno.
12045 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

12051 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
12054 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
12056 * gnutls.c (emacs_gnutls_handshake):
12057 Add QUIT to make the loop interruptible.
12059 2012-06-29 Glenn Morris <rgm@gnu.org>
12061 * charset.c (init_charset): Make lack of etc/charsets fatal.
12063 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
12065 * editfns.c (region_limit): Fix type mismatch.
12067 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
12069 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
12070 undefined. Convert from xassert to eassert.
12071 * nsmenu.m: Convert from xassert to eassert.
12072 * nsterm.m: Likewise.
12074 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
12076 * editfns.c (region_limit): Clip to narrowing (bug#11770).
12078 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
12080 Avoid integer overflow on scroll-left and scroll-right.
12081 * window.c (HSCROLL_MAX): New macro.
12082 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
12083 overflow when requested scroll falls outside ptrdiff_t range.
12085 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
12087 * window.h (struct window): Change type of 'hscroll',
12088 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
12089 'last_modified' and 'last_overlay_modified' to EMACS_INT.
12090 Adjust users accordingly.
12091 * xdisp.c (try_cursor_movement): Replace type check with eassert.
12092 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
12093 from EMACS_INT to ptrdiff_t.
12094 (make_window): Omit redundant initialization.
12096 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

12113 Fix GLYPH_DEBUG usage assuming that it may be undefined,
12114 adjust comments accordingly.

12177 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
12179 * alloc.c (allocate_string): Remove two redundant calls
12180 to memset, add explicit initialization where appropriate.

12193 on Mac OS X Lion: __mod_init_func and __mod_term_func.
12195 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
12196 when building with Clang.

12227 * alloc.c: Remove build_string.
12228 * lisp.h: Define build_string as static inline. This provides
12229 a better opportunity to optimize away calls to strlen when the
12230 function is called with compile-time constant argument.
12231 * image.c (imagemagick_error): Convert to build_string.
12232 * w32proc.c (sys_spawnve): Likewise.
12233 * xterm.c (x_term_init): Likewise.
12235 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12237 Use sprintf return value instead of invoking strlen on result.
12238 In the old days this wasn't portable, since some sprintf
12239 implementations returned char *. But they died out years ago and
12240 Emacs already assumes sprintf returns int.
12241 Similarly for float_to_string.
12242 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
12243 * ccl.c (ccl_driver):
12244 * character.c (string_escape_byte8):

12247 * print.c (print_object):
12248 * xdisp.c (message_dolog):
12249 * xfns.c (syms_of_xfns):
12250 Use sprintf or float_to_string result to avoid need to call strlen.
12251 * data.c (Fnumber_to_string):
12252 Use make_unibyte_string, since the string must be ASCII.
12253 * lisp.h, print.c (float_to_string): Now returns int length.
12254 * term.c (produce_glyphless_glyph):
12255 Use sprintf result rather than recomputing it.
12257 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
12258 * Makefile.in (ALL_CFLAGS):
12259 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
12260 * gmalloc.c, regex.c: Include <config.h> unconditionally.
12262 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12264 * dispextern.h (xstrcasecmp): Define to library function
12265 strcasecmp if available.
12266 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
12268 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
12270 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

12281 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
12283 * gtkutil.c (get_utf8_string): Remove redundant assignment.
12284 sprintf already null-terminates its output.
12286 * xfns.c (x_window): Remove redundant cast.
12288 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12290 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
12291 `const char *' to `char *' to avoid compiler warning.
12293 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12295 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12296 instead of truncating it to 63 (admittedly a generous limit).
12298 * process.c: Fix spelling and caps in comments.
12300 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
12302 * emacs.c (setpgrp): Remove definition, unused.

12312 (SYSTIME_H): Add nt/inc/sys/time.h.
12314 * systime.h [WINDOWSNT]: Include sys/time.h.
12316 * s/ms-w32.h (struct timespec): Definition moved from
12317 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
12319 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

12349 Remove unnecessary forward decls.
12351 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12353 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
12354 * lisp.h (WAIT_READING_MAX): New macro.
12355 * dispnew.c (Fsleep_for, sit_for):
12356 * keyboard.c (kbd_buffer_get_event):
12357 * process.c (Faccept_process_output):
12358 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
12359 This improves on the previous patch, which introduced a bug
12360 when time_t is unsigned and as wide as intmax_t.
12361 See <http://bugs.gnu.org/9000#51>.
12363 2012-06-23 Eli Zaretskii <eliz@gnu.org>
12365 * dispnew.c (sit_for, Fsleep_for):
12366 * keyboard.c (kbd_buffer_get_event):
12367 * process.c (Faccept_process_output): Avoid compiler warnings when
12368 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
12370 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
12372 * makefile.w32-in: Update dependencies.
12374 * w32.c (ltime): Add return type and declare static.
12375 (w32_get_internal_run_time): Remove usused variable `time_100ns'.

12379 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
12380 Privately reported by Herbert J. Skuhra.
12381 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
12383 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
12384 not make_lisp_timeval, when the argument is of type EMACS_TIME.
12386 2012-06-23 Eli Zaretskii <eliz@gnu.org>
12388 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
12389 last argument of make_unibyte_string.
12391 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
12392 language ID in the event parameters.
12394 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12395 event.code, not the obscure "character set ID".
12397 2012-06-23 Chong Yidong <cyd@gnu.org>
12399 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
12401 2012-06-23 Eli Zaretskii <eliz@gnu.org>
12403 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

12413 in the logic of incrementing and decrementing the value of
12414 use_relocatable_buffers.

12418 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
12419 Privately reported by Herbert J. Skuhra.
12420 [__FreeBSD__]: Remove "*/" typo after "#include".

12422 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
12423 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
12424 Don't assume EMACS_TIME and struct timeval are the same type.
12426 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12428 Support higher-resolution time stamps (Bug#9000).
12429 The time stamps are only nanosecond-resolution at the C level,
12430 since that's the best that any real-world system supports now.
12431 But they are picosecond-resolution at the Lisp level, as that's
12432 easy, and leaves room for future OS improvements.
12434 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12437 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12438 Don't get current time unless it's needed.
12440 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12441 now provides it if it's absent.
12442 (start_atimer): Port to higher-res time stamps.
12443 Check for time stamp overflow. Don't get current time more
12444 often than is needed.
12446 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12447 Include systime.h, not time.h.
12448 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12450 * dired.c: Include stat-time.h.
12451 (Ffile-attributes): File times now have higher resolution.
12453 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12454 (struct image): Timestamp now has higher resolution.
12456 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12457 has at least microseconds now. All uses removed.
12458 (update_frame, update_single_window, update_window, update_frame_1)
12459 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12460 (duration_to_sec_usec): Remove; no longer needed.
12462 * editfns.c (time_overflow): Now extern.
12463 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12464 (float-time, Fformat_time_string, Fcurrent_time_string)
12465 (Fcurrent_time_zone): Accept and generate higher-resolution
12467 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
12468 (decode_time_components, lisp_seconds_argument): New functions.
12469 (make_time): Now static.
12470 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12471 Report an error if the time is invalid, rather than having the caller
12474 * fileio.c: Include <stat-time.h>
12475 (Fcopy_file): Copy higher-resolution time stamps.
12476 Prefer to set the time stamp via a file descriptor if that works.
12477 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12478 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12479 (Fvisited_file_modtime, Fset_visited_file_modtime):
12480 Support higher-resolution time stamps.
12482 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12484 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12486 * image.c (prepare_image_for_display, clear_image_cache)
12487 (lookup_image): Port to higer-resolution time stamps.
12489 * keyboard.c (start_polling, bind_polling_period):
12490 Check for time stamp overflow.
12491 (read_char, kbd_buffer_get_event, timer_start_idle)
12492 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12493 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12494 Port to higher-resolution time stamps. Do not assume time_t is signed.
12495 (decode_timer): New function. Timers are now vectors of length 9,
12496 not 8, to accommodate the picosecond component.
12497 (timer_check_2): Use it.
12499 * nsterm.m (select_timeout, timeval_subtract): Remove.
12500 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12501 as they're a bit more accurate and handle overflow better.
12502 (ns_select): Change prototype to be compatible with pselect.
12503 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12504 * nsterm.h (ns_select): Adjust prototype.
12506 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12507 us-resolution time stamps.
12508 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12510 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12512 * lisp.h (time_overflow): New decl.
12513 (wait_reading_process_output): First arg is now intmax_t, not int,
12514 to accommodate larger waits.
12516 * process.h (struct Lisp_Process.read_output_delay):
12517 Now counts nanoseconds, not microseconds.
12518 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12520 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12521 (wait_reading_process_output):
12522 Port to ns-resolution time stamps.
12523 (Faccept_process_output, wait_reading_process_output):
12524 Check for time stamp overflow. Do not assume time_t is signed.
12525 (select_wrapper): Remove; we now use pselect.
12526 (Fprocess_attributes): Now generates ns-resolution time stamps.
12528 * sysdep.c: Include utimens.h. Don't include utime.h
12529 or worry about struct utimbuf; gnulib does that for us now.
12530 (gettimeofday): Remove; gnulib provides a substitute.
12531 (make_timeval): New function.
12532 (set_file_times): Now sets ns-resolution time stamps.
12533 New arg FD; all uses changed.
12534 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12535 (system_process_attributes):
12536 Now returns ns-resolution time stamp. All uses changed.
12537 Check for time stamp overflow.
12539 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12540 provides a substitute now.
12542 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12543 since it guarantees struct timespec.
12544 (EMACS_TIME): Now struct timespec, so that we can support
12545 ns-resolution time stamps.
12546 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12547 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12548 (EMACS_USECS): Remove.
12549 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12550 so multiply the arg by 1000 before storing it.
12551 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12553 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12554 Port to ns-resolution time stamps.
12555 (EMACS_TIME_NEG_P): Remove; replaced by....
12556 (EMACS_TIME_SIGN): New macro.
12557 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
12558 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12559 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12560 (make_timeval, make_lisp_time, decode_time_components): New decls.
12561 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12562 that it mishandled time_t overflow. You can't compare by subtracting!
12563 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12564 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12566 * term.c: Include <sys/time.h>.
12567 (timeval_to_Time): New function, for proper overflow wraparound.
12568 (term_mouse_position, term_mouse_click): Use it.
12570 * undo.c (record_first_change): Support higher-resolution time stamps
12571 in the undo buffer.
12572 (Fprimitive_undo): Use them when restoring time stamps.
12574 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12575 (w32_get_internal_run_time):
12576 Port to higher-resolution Emacs time stamps.
12577 (ltime): Now accepts single 64-bit integer, as that's more convenient
12580 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12582 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12583 for compatibility with pselect. Support ns-resolution time stamps.
12585 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12587 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12588 Check for time stamp overflow, and support ns-resolution time stamps.
12590 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12591 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12592 (timeval_subtract): Remove; no longer needed.
12593 (XTflash, XTring_bell, x_wait_for_event):
12594 Port to ns-resolution time stamps. Don't assume time_t is signed.
12596 2012-06-22 Chong Yidong <cyd@gnu.org>
12598 * xdisp.c (x_consider_frame_title): Revert last change.
12600 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12602 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12603 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12604 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12605 staticidx goes up to 1597 out of 1600 = 0x640.)
12607 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12609 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12610 Otherwise, the umask might be mistakenly 0 while handling input signals.
12612 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

13063 * buffer.c (buffer_local_value_1): New function, split from
13064 Fbuffer_local_value; can return Qunbound.
13065 (Fbuffer_local_value): Use it.
13066 (Vmode_line_format): Docstring tweaks.
13068 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
13070 * sysdep.c (system_process_attributes): Improve comment.
13072 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
13074 * keyboard.c: Export real-this-command to Elisp.
13075 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
13076 and DEFVAR it. Update all users.
13078 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
13080 * minibuf.c (Fassoc_string): Remove duplicate declaration.
13082 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
13083 Convert pctcpu and pctmem to Lisp float properly.
13084 Let the compiler fold better, as 100.0/0x8000 is exact.
13086 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
13088 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
13091 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
13093 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
13095 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
13097 For a 'struct window', replace some Lisp_Object fields to
13098 bitfields where appropriate, remove unused fields.
13099 * window.h (struct window): Remove unused 'last_mark_x' and
13100 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
13101 change its type from Lisp_Object to bitfield.
13102 Change type of 'force_start', 'optional_new_start',
13103 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
13104 fields from Lisp_Object to bitfield. Adjust users accordingly.
13106 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13108 Pacify gcc -Wdouble-precision when using Xaw.
13109 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
13110 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
13111 Use 'float' consistently, rather than 'float' in most places
13112 and 'double' in a couple of places.
13114 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13116 * xdisp.c (handle_stop): Detect whether we have overlay strings
13117 loaded by testing it->current.overlay_string_index to be
13118 non-negative, instead of checking whether n_overlay_strings is
13119 positive. (Bug#11587)
13121 2012-05-31 Chong Yidong <cyd@gnu.org>
13123 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
13125 * doc.c (Fsubstitute_command_keys): Doc fix.
13127 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13129 * search.c (search_buffer): Remove calls to
13130 r_alloc_inhibit_buffer_relocation, as it is now called by
13131 maybe_unify_char, which was the cause of relocation of buffer text
13134 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13136 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
13137 for the duration of call to load_charset, to avoid problems with
13138 callers of maybe_unify_char that access buffer text through C
13141 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
13142 decrement the inhibition flag, instead of just setting or
13145 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13147 Remove obsolete '#define static' cruft.
13148 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
13149 This #undef was "temporary" in 2000; it is no longer needed
13150 now that '#define static' has gone away.
13151 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
13152 (gray_bitmap_bits): Remove; no longer needed.
13153 All uses replaced with definiens.
13154 * xterm.c: Include "bitmaps/gray.xbm".
13156 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13158 Clean up __executable_start, monstartup when --enable-profiling.
13159 The following changes affect the code only when profiling.
13160 * dispnew.c (__executable_start): Rename from safe_bcopy.
13161 Define only on platforms that need it.
13162 * emacs.c: Include <sys/gmon.h> when profiling.
13163 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
13164 (__executable_start): Remove decl, since lisp.h does it now.
13165 (safe_bcopy): Remove decl; no longer has that name.
13166 (main): Coalesce #if into single bit of code, for simplicity.
13167 Cast pointers to uintptr_t, since standard libraries want integers
13169 * lisp.h (__executable_start): New decl.
13171 2012-05-31 Glenn Morris <rgm@gnu.org>
13173 * image.c (Fimagemagick_types): Doc fix.
13175 2012-05-30 Jim Meyering <meyering@redhat.com>
13177 * callproc.c (Fcall_process_region): Include directory component
13178 in mkstemp error message (Bug#11586).
13180 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13182 * alloc.c, lisp.h (make_pure_vector): Now static.
13184 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
13186 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
13187 Move to byte-run.el.

13189 * data.c (Fdefalias): Purify definition, except for keymaps.
13190 (Qdefun): Move from eval.c.
13191 * lisp.h (Qdefun): Remove.
13192 * lread.c (read1): Tiny simplification.
13194 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
13196 Do not create empty overlays with the evaporate property (Bug#9642).
13197 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13198 Bug#9642, but explicitly check that the buffer the overlay would
13199 be moved to is live and rearrange lines to make sure that errors
13200 will not put the overlay in an inconsistent state.
13201 (Fdelete_overlay): Cosmetics.
13203 2012-05-28 Eli Zaretskii <eliz@gnu.org>
13205 * w32term.c (my_bring_window_to_top): New function.
13206 (x_raise_frame): Use handle returned by DeferWindowPos, which
13207 could be different from the original one.
13208 Call my_bring_window_to_top instead of my_set_foreground_window.
13211 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
13212 by calling BringWindowToTop.
13214 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

13217 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
13219 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13220 This avoids undefined behavior that might cause the eassert
13221 to not catch an out-of-range value.
13223 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13225 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
13226 Update dependencies.
13228 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13230 * bidi.c (bidi_mirror_char): Fix last change.
13232 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
13234 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
13235 when referring to sectname field in printf format.
13237 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
13239 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
13240 Only r_alloc_inhibit_buffer_relocation needed to be added;
13241 the others were already declared.
13243 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13244 before checking whether it's out of range. Put the check inside
13246 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
13248 2012-05-27 Ken Brown <kbrown@cornell.edu>
13250 * callproc.c (Fcall_process): Restore a line that was accidentally
13251 commented out in the 2011-02-13 change (bug#11547).
13253 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13255 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13256 defined on ralloc.c.
13258 * buffer.c [REL_ALLOC]: Remove prototypes of
13259 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
13260 they are now on lisp.h.
13262 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13264 * search.c (search_buffer): Use it to inhibit relocation of buffer
13265 text while re_search_2 is doing its job, because re_search_2 is
13266 passed C pointers to buffer text. (Bug#11519)
13268 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13269 Update value to 24.
13271 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13272 state after an additional call to move_it_in_display_line_to, keep
13273 the values of it->max_ascent and it->max_descent found for the
13275 (pos_visible_p): Revert the comparison against bottom_y to what it
13276 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13279 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13281 Fix coding-related core dumps with gcc -ftrapv.
13282 The code was computing A - B, where A and B are pointers, and B is
13283 random garbage. This can lead to core dumps on platforms that
13284 have special pointer registers, and it also leads to core dumps on
13285 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13286 A - B only when B is initialized properly.
13287 * coding.c (coding_set_source, coding_set_destination): Return void.
13288 (coding_change_source, coding_change_destinations): New functions,
13289 with the old behaviors of coding_set_source and coding_set_destination.
13290 All callers that need an offset changed to use these new functions.
13292 2012-05-26 Glenn Morris <rgm@gnu.org>
13294 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
13296 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13298 Extend mouse support on W32 text-mode console.
13299 * xdisp.c (draw_row_with_mouse_face):
13300 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13302 * w32console.c: Include window.h.
13303 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13305 (initialize_w32_display): Initialize mouse-highlight data.
13307 * w32inevt.c: Include termchar.h and window.h.
13308 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13309 moves, call note_mouse_highlight. If help_echo changed, call
13310 gen_help_event to produce help-echo message in the echo area.
13311 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13314 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13316 * lread.c (read1): Simplify slightly to avoid an overflow warning
13317 with GCC 4.7.0 on x86-64.
13319 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13321 * bidi.c (bidi_mirror_char): Revert last change: an int is
13322 definitely wide enough here.
13324 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13326 Fix integer width and related bugs (Bug#9874).
13327 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
13328 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
13329 (string_bytes, check_sblock, allocate_string_data):
13330 (compact_small_strings, Fmake_bool_vector, make_string)
13331 (make_unibyte_string, make_multibyte_string)
13332 (make_string_from_bytes, make_specified_string)
13333 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
13334 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
13336 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13337 (allocate_pseudovector):
13338 Use int, not EMACS_INT, where int is wide enough.
13339 (inhibit_garbage_collection, Fgarbage_collect):
13340 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13341 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13342 int might not be wide enough.
13343 (bidi_cache_search, bidi_cache_find, bidi_init_it)
13344 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
13345 (bidi_at_paragraph_end, bidi_find_paragraph_start)
13346 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
13347 (bidi_level_of_next_char, bidi_move_to_visually_next):
13348 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13349 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
13350 (Fkill_buffer, Fset_buffer_major_mode)
13351 (advance_to_char_boundary, Fbuffer_swap_text)
13352 (Fset_buffer_multibyte, overlays_at, overlays_in)
13353 (overlay_touches_p, struct sortvec, record_overlay_string)
13354 (overlay_strings, recenter_overlay_lists)
13355 (adjust_overlays_for_insert, adjust_overlays_for_delete)
13356 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
13357 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
13358 (Foverlay_recenter, last_overlay_modification_hooks_used)
13359 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13360 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13361 (validate_region): Omit unnecessary test for b <= e,
13362 since that's guaranteed by the previous test.
13363 (adjust_overlays_for_delete): Avoid pos + length overflow.
13364 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13365 (report_overlay_modification):
13366 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13367 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13368 Omit pointer cast, which isn't needed anyway, and doesn't work
13369 after the EMACS_INT -> ptrdiff_t change.
13370 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13371 * buffer.h: Adjust decls to match defn changes elsewhere.
13372 (struct buffer_text, struct buffer):
13373 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13374 Use EMACS_INT, not int, where int might not be wide enough.
13375 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13376 not int, to avoid needless 32-bit limit on 64-bit hosts.
13377 (exec_byte_code): Use tighter memory-full test, one that checks
13378 for alloca overflow. Don't compute the address of the object just
13379 before an array, as that's not portable. Use EMACS_INT, not
13380 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13381 * callint.c (Fcall_interactively):
13382 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13383 * callproc.c (call_process_kill, Fcall_process):
13384 Don't assume pid_t fits into an Emacs fixnum.
13385 (call_process_cleanup, Fcall_process, child_setup):
13386 Don't assume pid_t fits into int.
13387 (call_process_cleanup, Fcall_process, delete_temp_file)
13388 (Fcall_process_region):
13389 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13390 (Fcall_process): Simplify handling of volatile integers.
13391 Use int, not EMACS_INT, where int will do.
13392 * casefiddle.c (casify_object, casify_region, operate_on_word)
13393 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13394 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13395 (casify_object): Avoid integer overflow when overallocating buffer.
13396 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13397 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13398 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13399 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13400 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13401 integers are now checked earlier. All uses replaced with XINT.
13403 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13404 For CCL_MapSingle, check that content and value are in int range.
13405 (ccl_driver, Fregister_code_conversion_map):
13406 Check that Vcode_version_map_vector is a vector.
13407 (resolve_symbol_ccl_program): Check that vector header is in range.
13408 Always copy the vector, so that we can check its contents reliably
13409 now rather than having to recheck each instruction as it's being
13410 executed. Check that vector words fit in 'int'.
13411 (ccl_get_compiled_code, Fregister_ccl_program)
13412 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13413 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13414 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13415 contents are in range.
13416 (Fccl_execute_on_string): Check that status is in range.
13417 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13418 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13419 Accept and return EMACS_INT, not int, because callers can pass values
13420 out of 'int' range.
13421 (c_string_width, strwidth, lisp_string_width, chars_in_text)
13422 (multibyte_chars_in_text, parse_str_as_multibyte)
13423 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
13424 (str_as_unibyte, str_to_unibyte, string_count_byte8)
13425 (string_escape_byte8, Fget_byte):
13426 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13427 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13428 avoid mishandling large integers.
13429 * character.h: Adjust decls to match defn changes elsewhere.
13430 * charset.c (load_charset_map_from_file, find_charsets_in_text)
13431 (Ffind_charset_region):
13432 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13433 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
13434 (load_charset_map_from_vector, Fdefine_charset_internal):
13435 Don't assume fixnum fits in int.
13436 (load_charset_map_from_vector, Fmap_charset_chars):
13437 Remove now-unnecessary CHECK_NATNUMs.
13438 (Fdefine_charset_internal): Check ranges here, more carefully.
13439 Don't rely on undefined behavior with signed left shift overflow.
13440 Don't assume unsigned int fits into fixnum, or that fixnum fits
13441 into unsigned int. Don't require max_code to be a valid fixnum;
13442 that's not true for gb10830 4-byte on a 32-bit host. Allow
13443 invalid_code to be a cons, for the same reason. Require code_offset
13444 to be a character. Avoid int overflow if max_char is close
13446 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13447 this is intended anyway and avoids some undefined behavior.
13448 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13449 INDEX_TO_CODE_POINT, as that's what it expects.
13450 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13451 * charset.h (DECODE_CHAR): Return int, not unsigned;
13452 this is what was intended anyway, and it avoids undefined behavior.
13453 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13454 integer-overflow issues.
13455 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13456 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13457 where the argument is EMACS_INT, and this behavior is not intended.
13458 * chartab.c (Fmake_char_table, Fset_char_table_range)
13459 (uniprop_get_decoder, uniprop_get_encoder):
13460 Don't assume fixnum fits in int.
13461 * cmds.c (move_point): New function, that does the gist of
13462 Fforward_char and Fbackward_char, but does so while checking
13463 for integer overflow more accurately.
13464 (Fforward_char, Fbackward_char): Use it.
13465 (Fforward_line, Fend_of_line, internal_self_insert)
13466 (internal_self_insert):
13467 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13468 Fix a FIXME, by checking for integer overflow when calculating
13469 target_clm and actual_clm.
13470 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
13471 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

14150 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
14153 This directory predates autoconf and is no longer needed nowadays.
14154 Move its few remaining bits of functionality to where they're needed.
14155 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
14156 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
14157 * m/template.h: Remove.
14158 * Makefile.in (M_FILE): Remove. All uses removed.
14159 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
14160 * lisp.h (USE_LSB_TAG):
14161 * mem-limits.h (EXCEEDS_LISP_PTR):
14162 Use VAL_MAX, not VALBITS, in #if.
14163 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
14164 (EMACS_UINT): Define unconditionally now.
14165 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
14166 (BITS_PER_EMACS_INT): New constants, replacing
14167 what used to be in config.h, but not useful in #if.
14168 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
14169 define them any more.
14170 (VAL_MAX): New macro.
14172 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
14173 BITS_PER_EMACS_INT, in #if.
14174 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
14175 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
14176 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
14177 * s/ms-w32.h (DATA_START):
14178 Move here from removed file m/intel386.h.
14179 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
14180 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
14182 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
14184 Assume C89 or later.
14185 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
14186 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
14188 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
14189 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
14190 * textprop.c, tparam.c (NULL): Remove.
14191 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
14192 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
14193 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
14194 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
14195 * xterm.c (input_signal_count): Assume volatile works.
14197 2012-05-21 Ken Brown <kbrown@cornell.edu>
14199 * xgselect.c (xg_select): Fix first argument in call to 'select'
14202 2012-05-20 Ken Brown <kbrown@cornell.edu>
14204 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
14205 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
14207 2012-05-19 Ken Brown <kbrown@cornell.edu>
14209 * xfns.c (x_in_use): Remove `static' qualifier.
14210 * xterm.h (x_in_use): Declare.
14211 * xgselect.c: Include xterm.h.
14212 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
14213 and `display_arg' (bug#9754).
14215 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
14217 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
14219 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
14220 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
14222 2012-05-18 Eli Zaretskii <eliz@gnu.org>
14224 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
14226 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
14227 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
14229 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
14230 reference to image_cache->refcount.
14231 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
14233 2012-05-17 Juri Linkov <juri@jurta.org>
14235 * search.c (Fword_search_regexp, Fword_search_backward)
14236 (Fword_search_forward, Fword_search_backward_lax)
14237 (Fword_search_forward_lax): Move functions to isearch.el
14238 (bug#10145, bug#11381).
14240 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
14242 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
14244 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
14246 * lread.c (init_obarray): Declare Qt and Qnil as special.
14248 2012-05-14 Glenn Morris <rgm@gnu.org>
14250 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
14251 Put "libexec" before "bin", for the sake of init_callproc_1.
14253 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14255 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
14257 * unexaix.c: Port to more-recent AIX compilers.
14258 (report_error, report_error_1, make_hdr, copy_sym)
14259 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
14260 Make arguments const char *, not char *, to avoid violations of C
14261 standard and to fix some AIX warnings reported by Gilles Pion.
14263 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14265 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
14266 already have overlays loaded.
14267 (handle_single_display_spec): Before returning without displaying
14268 fringe bitmap, synchronize the bidi iterator with the main display
14269 iterator, by calling iterate_out_of_display_property.
14270 (iterate_out_of_display_property): Detect buffer iteration by
14271 testing that it->string is a Lisp string.
14272 (get_next_display_element): When the current object is exhausted,
14273 and there's something on it->stack, call set_iterator_to_next to
14274 proceed with what's on the stack, instead of returning zero.
14275 (set_iterator_to_next): If called at the end of a Lisp string,
14276 proceed to consider_string_end without incrementing string
14277 position. Don't increment display vector index past the end of
14278 the display vector. (Bug#11417)
14279 (pos_visible_p): Don't report a position visible when move_it_to
14280 stopped at the last line of window, which happens to be scanned
14281 backwards by the bidi iteration. (Bug#11464)
14283 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14285 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14286 and right-margin display specs even if the spec is invalid or we
14287 are on a TTY, and thus unable to display on the fringes.
14288 That's because the text with the property will not be displayed anyway,
14289 so we need to signal to the caller that this is a "replacing"
14290 display spec. This fixes display when the spec is invalid or we
14293 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14295 * unexaix.c (make_hdr): Fix typo in prototype.
14296 This bug broke the build on AIX. Problem reported by Gilles Pion.
14298 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
14300 * keyboard.c (kbd_buffer_get_event): Read special events also in
14301 batch mode. (Bug#11415)
14303 2012-05-12 Glenn Morris <rgm@gnu.org>
14305 * ns.mk: Update for ns_appbindir no longer having trailing "/".
14307 2012-05-12 Eli Zaretskii <eliz@gnu.org>
14309 * lisp.mk (lisp): Add newcomment.elc.
14311 2012-05-12 Glenn Morris <rgm@gnu.org>
14313 * Makefile.in (MKDIR_P): New, set by configure.
14314 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
14316 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
14318 Remove unused function hourglass_started.
14319 * dispextern.h (hourglass_started):
14320 * w32fns.c (hourglass_started):
14321 * xdisp.c (hourglass_started): Remove.
14323 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
14325 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
14326 Update dependencies.
14328 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14330 * xgselect.c (xg_select): Put maxfds+1 into a var.
14331 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14333 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14335 2012-05-10 Dave Abrahams <dave@boostpro.com>
14337 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14338 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14340 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14342 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14343 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14344 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14345 Initialize xd_registered_buses.
14347 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14349 Untag more efficiently if USE_LSB_TAG.
14350 This is based on a proposal by YAMAMOTO Mitsuharu in
14351 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14352 For an admittedly artificial (nth 8000 longlist) benchmark on
14353 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14354 Emacs's overall text size by 1%.
14355 * lisp.h (XUNTAG): New macro.
14356 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14357 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14358 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14359 * eval.c (Fautoload):
14360 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14361 * frame.h (XFRAME): Use XUNTAG.
14363 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14364 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14365 Remove unportable assumptions about print widths of types like
14367 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14368 intptr_t when converting between pointer and integer, to avoid GCC
14369 warnings about wrong width.
14371 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14373 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14374 stack for each reader_thread, instead of defaulting to 8MB
14375 determined by the linker. This avoids failures in creating
14376 subprocesses on Windows 7, see the discussion in this thread:
14377 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14379 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14381 Fix up display of the *Minibuf-0* buffer in the mini window.
14382 * keyboard.c (read_char): Don't clear the echo area if there's no
14384 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14385 contents of *Minibuf-0*) if there's no message displayed in its stead.
14387 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14389 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14392 2012-05-06 Chong Yidong <cyd@gnu.org>
14394 * lisp.mk (lisp): Update.
14396 2012-05-05 Jim Meyering <meyering@redhat.com>
14398 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14400 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14402 * data.c (PUT_ERROR): New macro.
14403 (syms_of_data): Use it. Add new error type `user-error'.
14404 * undo.c (user_error): New function.
14405 (Fprimitive_undo): Use it.
14406 * print.c (print_error_message): Adjust print style for `user-error'.
14407 * keyboard.c (user_error): New function.
14408 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14410 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14412 Do not limit current-time-string to years 1000..9999.
14413 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14414 (Fcurrent_time_string): Support any year that is supported by the
14415 underlying localtime representation. Don't use asctime, as it
14416 has undefined behavior for years outside the range -999..9999.
14418 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14420 Fix race conditions involving setenv, gmtime, localtime, asctime.
14421 Without this fix, interrupts could mess up code that uses these
14422 nonreentrant functions, since setting TZ invalidates existing
14423 tm_zone or tzname values, and since most of these functions return
14424 pointers to static storage.
14425 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14426 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14427 Grow the critical sections to include not just invoking
14428 localtime/gmtime, but also accessing these functions' results
14429 including their tm_zone values if any, and any related TZ setting.
14430 (format_time_string): Last arg is now struct tm *, not struct tm **,
14431 so that the struct tm is saved in the critical section.
14432 All callers changed. Simplify allocation of initial buffer, partly
14433 motivated by the fact that memory allocation needs to be outside
14434 the critical section.
14436 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14438 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14439 with RESET_INTERVAL.
14441 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14442 Remove duplicated buffer name initialization.
14444 2012-05-02 Jim Meyering <jim@meyering.net>
14446 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14448 * xfns.c (x_window): Use xstrdup (Bug#11375).
14450 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14452 * xdisp.c (pos_visible_p): If already at a newline from the
14453 display string before the 'while' loop, don't walk back the glyphs
14454 from it3.glyph_row. Solves assertion violation when the display
14455 string begins with a newline (egg.el). (Bug#11367)
14457 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14459 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14462 2012-05-01 Glenn Morris <rgm@gnu.org>
14464 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14465 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14466 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14467 All were removed before 23.1.
14469 * dispnew.c: Remove HAVE_LIBNCURSES test;
14470 it is always true on relevant platforms.
14472 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14473 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14475 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14477 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14479 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14480 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14483 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14485 Do not avoid creating empty evaporating overlays (Bug#9642).
14486 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14487 That is, do not delete an evaporating overlay if it becomes
14488 empty after its bounds are adjusted to fit within its buffer.
14489 This fix caused other problems, and I'm reverting it until we get
14490 to the bottom of them.
14492 2012-04-27 Chong Yidong <cyd@gnu.org>
14494 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14496 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14498 * xdisp.c (pos_visible_p): If the window start position is beyond
14499 ZV, start the display from buffer beginning. Prevents assertion
14500 violation in init_iterator when the minibuffer window is scrolled
14501 via the scroll bar.
14503 * window.c (window_scroll_pixel_based): Likewise.
14505 2012-04-27 Chong Yidong <cyd@gnu.org>
14507 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14509 2012-04-27 Glenn Morris <rgm@gnu.org>
14511 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14512 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14514 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14516 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14517 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14519 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14521 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14522 display element, check also the underlying string or buffer
14523 character. (Bug#11341)
14525 * w32menu.c: Include w32heap.h.
14526 (add_menu_item): If the call to AppendMenuW (via
14527 unicode_append_menu) fails, disable Unicode menus only if we are
14528 running on Windows 9X/Me.
14530 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14532 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14533 (xgetint): Add missing shift for LSB tags.
14535 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14537 * keyboard.c (read_char): Don't wipe echo area for select window
14538 events: These might get delayed via `mouse-autoselect-window'
14541 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14543 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14544 manipulation of :loaded-from data.
14546 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14548 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14549 now a cons (bug#11311).
14551 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14553 Do not create empty overlays with the evaporate property (Bug#9642).
14554 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14555 if it becomes empty after its bounds are adjusted to fit within
14556 its buffer. Without this fix, in a nonempty buffer (let ((o
14557 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14558 yields an empty overlay that has the evaporate property, which is
14559 not supposed to happen.
14561 Fix minor GTK3 problems found by static checking.
14562 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14563 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14564 (struct _EmacsFixedClass, emacs_fixed_get_type):
14565 Move decls here from emacsgtkfixed.h, since they needn't be public.
14566 (emacs_fixed_get_type): Now static.
14567 (emacs_fixed_class_init): Omit unused local.
14568 (emacs_fixed_child_type): Remove; unused.
14569 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14570 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14571 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14572 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14573 (EMACS_FIXED_GET_CLASS): Remove; unused.
14574 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14576 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14577 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14579 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14581 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14582 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14583 (__malloc_size_t, __malloc_ptrdiff_t):

14672 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
14674 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14676 * sysdep.c [__FreeBSD__]: Minor cleanups.
14677 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14678 Use Emacs indenting style more consistently. Avoid some casts.

14704 * process.c (wait_reading_process_output): If EIO occurs on a pty,
14705 set the status to "failed" and ensure that sentinel is run.
14707 2012-04-20 Glenn Morris <rgm@gnu.org>
14709 * process.c (Fset_process_inherit_coding_system_flag)
14710 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

14760 New extern decls, to avoid calling undeclared functions.
14761 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14762 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14763 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14764 (NEED_MEM_INSERT): New macro.
14765 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14766 Remove one incorrect comment and fix another.

14781 Remove decls. This fixes an "It stinks!".
14783 * alloc.c (which_symbols): Fix alignment issue / type clash.
14785 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14787 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14788 (struct Lisp_Misc_Any): Likewise.
14789 (struct Lisp_Free): Likewise.

14801 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14802 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14803 * s/netbsd.h, s/sol2-6.h:
14804 Remove definition of GC_MARK_STACK, since the default now works.
14805 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14806 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14807 no longer the default.
14808 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14810 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14833 2012-04-11 Daniel Colascione <dancol@dancol.org>
14835 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14836 against is gone. It's better to use vfork now so that when Cygwin
14837 gains a new, working vfork, we use it automatically (bug#10398).
14839 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14860 being loaded (bug#10424).
14862 2012-04-09 Glenn Morris <rgm@gnu.org>
14864 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14865 not just in the obarray, before snarfing them. (Bug#11036)

14882 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14883 attempts per process (connection).
14885 2012-04-09 Chong Yidong <cyd@gnu.org>
14887 * eval.c (Fuser_variable_p, user_variable_p_eh)

14889 (Fdefvar): Caller changed.
14891 * callint.c (Finteractive, Fcall_interactively):
14892 * minibuf.c (Fread_variable): Callers changed.
14894 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14896 * xdisp.c (set_cursor_from_row): If the display string appears in
14897 the buffer at position that is closer to point than the position
14898 after the display string, display the cursor on the first glyph of
14899 the display string. Fixes cursor display when a 'display' text
14900 property immediately follows invisible text. (Bug#11094)
14902 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14904 composite.c: use 'double' consistently
14905 * composite.c (get_composition_id): Use 'double' consistently
14906 instead of converting 'float' to 'double' and vice versa; this is
14907 easier to understand and avoids a GCC warning.
14909 2012-04-09 Glenn Morris <rgm@gnu.org>
14911 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14912 preparation for dumping it with emacs. (Bug#4789)

14934 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14935 (mark_memory): Mark Lisp_Objects only if pointers might hide in

14951 ($(BLD)/xml.$(O)): New dependency list.
14953 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14954 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14955 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14956 [!WINDOWSNT]: New macros.
14957 (init_libxml2_functions, libxml2_loaded_p): New functions.
14958 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14959 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14960 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14961 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14963 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14964 Call init_libxml2_functions before calling libxml2 functions.
14965 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14967 * emacs.c: Don't include libxml/parser.h.
14968 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14969 xmlCleanupParser directly.
14971 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14973 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14975 * indent.c (Fvertical_motion): If there is a display string at
14976 point, use it.vpos to compute how many lines to backtrack after
14977 move_it_to point. (Bug#11133)
14979 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14981 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14982 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14983 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14984 macros related to unification of CJK characters. For the details,
14985 see the discussion following the message here:
14986 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

14999 * w32menu.c (is_simple_dialog): Properly check lisp types.
15002 2012-03-31 Eli Zaretskii <eliz@gnu.org>
15004 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
15005 position we get to after a call to move_it_to fails the
15006 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
15007 only if we wind up in a string from display property. (Bug#11063)
15009 * window.c (Fdelete_other_windows_internal): Invalidate the row
15010 and column information about mouse highlight, so that redisplay
15011 restores it after reallocating the glyph matrices. (Bug#7464)
15013 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
15014 string comes from a `display' text property, use the buffer
15015 position of that property as if we actually saw that position in
15017 (move_it_by_lines): Remove the assertion that
15018 "it->current_x == 0 && it->hpos == 0" which can be legitimately
15019 violated when there's a before-string at the beginning of a line.
15022 2012-03-30 Eli Zaretskii <eliz@gnu.org>
15024 * xdisp.c (append_space_for_newline): If the default face was
15025 remapped, use the remapped face for the appended newline.
15026 (extend_face_to_end_of_line): Use the remapped default face for
15027 extending the face to the end of the line.
15028 (display_line): Call extend_face_to_end_of_line when the default
15029 face was remapped. (Bug#11068)

15039 2012-03-27 Glenn Morris <rgm@gnu.org>
15041 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
15044 2012-03-26 Kenichi Handa <handa@m17n.org>

15051 * keyboard.c (Vselection_inhibit_update_commands): New variable.
15052 (command_loop_1): Use it; inhibit selection update for
15053 handle-select-window too (Bug#8996).
15055 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
15057 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
15059 2012-03-25 Kenichi Handa <handa@m17n.org>
15061 * dispextern.h (struct glyph): Change the bit length of
15062 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
15064 2012-03-24 Eli Zaretskii <eliz@gnu.org>
15066 * s/ms-w32.h (tzname): Include time.h before redirecting to
15067 _tzname. Fixes the MSVC build. (Bug#9960)
15069 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
15071 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
15074 * xterm.c (XTread_socket): Only modify handling_signal if
15075 !SYNC_INPUT. (Bug#11080)
15077 2012-03-23 Eli Zaretskii <eliz@gnu.org>
15079 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
15080 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
15081 when fetching a multibyte character consumes more bytes than
15082 CHAR_BYTES returns, due to unification of CJK characters in
15083 string_char. (Bug#11073)
15085 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
15087 * process.c (wait_reading_process_output): Handle pty disconnect
15088 by refraining from sending oneself a SIGCHLD (bug#10933).

15096 (handle_face_prop): Use default face for prefix strings (Bug#4281).
15097 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.

15111 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
15112 to reflect default non-nil value of redisplay-dont-pause.
15114 2012-03-19 Kenichi Handa <handa@m17n.org>

15117 it fit in a valid range (Bug#11003).
15119 2012-03-18 Eli Zaretskii <eliz@gnu.org>
15121 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
15122 that is not from display property, accept the row as a "cursor
15123 row" if one of the string's character has a non-nil `cursor'
15124 property. Fixes cursor positioning when there are newlines in
15125 overlay strings, e.g. in icomplete.el. (Bug#11035)
15127 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
15129 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
15131 2012-03-12 Chong Yidong <cyd@gnu.org>
15133 * eval.c (inhibit_lisp_code): Rename from
15134 inhibit_window_configuration_change_hook; move from window.c.
15136 * xfns.c (unwind_create_frame_1, Fx_create_frame):
15137 * window.c (run_window_configuration_change_hook)
15138 (syms_of_window): Callers changed.

15158 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
15161 2012-03-03 Glenn Morris <rgm@gnu.org>
15163 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
15165 2012-03-02 Eli Zaretskii <eliz@gnu.org>
15167 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
15168 position past the first glyph_row that ends at ZV. (Bug#10902)
15169 (redisplay_window, next_element_from_string): Fix typos in
15171 (redisplay_window): Pass to move_it_vertically the margin in
15172 pixels, not in screen lines.
15174 2012-03-02 Glenn Morris <rgm@gnu.org>
15176 * buffer.c (buffer-list-update-hook): Doc fix.
15178 2012-02-29 Eli Zaretskii <eliz@gnu.org>
15180 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
15181 push_it before setting up the iterator for the first overlay
15182 string, even if we have an empty string loaded.
15183 (next_overlay_string): If there's an empty string on the iterator
15184 stack, pop the stack. (Bug#10903)
15186 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
15188 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15189 Suggested by Stefan Monnier in
15190 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15191 * alloc.c (widen_to_Lisp_Object): New static function.
15192 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15193 and widening them to Lisp_Objects. This would work even if
15194 USE_LSB_TAG is defined and wide integers are used, which might
15195 happen in a future version of Emacs.
15197 2012-02-25 Chong Yidong <cyd@gnu.org>
15199 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
15202 * xselect.c (Fx_selection_exists_p): Doc fix.
15203 (x_clipboard_manager_save_all): Print an informative message
15204 before saving to clipboard manager.
15206 2012-02-24 Chong Yidong <cyd@gnu.org>
15208 * keyboard.c (process_special_events): Handle all X selection
15209 requests in kbd_buffer, not just the next one (Bug#8869).
15211 2012-02-23 Chong Yidong <cyd@gnu.org>
15213 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
15214 call when setting menu-bar-lines and tool-bar-lines parameters.
15215 (unwind_create_frame_1): New helper function.
15217 * window.c (inhibit_window_configuration_change_hook): New var.
15218 (run_window_configuration_change_hook): Obey it.

15228 * fileio.c (Vfile_name_handler_alist): Doc fix.
15230 * buffer.c (Fget_file_buffer): Protect against invalid file
15231 handler return value.
15233 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
15235 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
15236 when computing $valmask.
15238 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15239 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15240 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15241 It's useless in that case, and it can cause problems on hosts
15242 that allocate halves of EMACS_INT values separately.
15243 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15244 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15245 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15246 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15247 it avoids undefined behavior on hosts where shifting right by more
15248 than the word width has undefined behavior.
15250 2012-02-19 Chong Yidong <cyd@gnu.org>
15252 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15253 (Funhandled_file_name_directory, Ffile_name_as_directory)
15254 (Fdirectory_file_name, Fexpand_file_name)
15255 (Fsubstitute_in_file_name): Protect against invalid file handler
15256 return values (Bug#10845).
15258 2012-02-18 Eli Zaretskii <eliz@gnu.org>
15260 * .gdbinit (pitx): Fix incorrect references to fields of the

15270 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
15272 2012-02-15 Chong Yidong <cyd@gnu.org>
15274 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
15275 marked as special. Also, starting docstrings with * is obsolete.

15290 2012-02-12 Chong Yidong <cyd@gnu.org>
15292 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
15293 as that creates a dangerous corner case.
15295 * window.c (Fdelete_window_internal): Invalidate the mouse
15296 highlight (Bug#9904).
15298 2012-02-12 Glenn Morris <rgm@gnu.org>

15301 (Fx_get_selection_internal, Fx_disown_selection_internal)
15302 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
15303 * nsselect.m (Fx_own_selection_internal)
15304 (Fx_disown_selection_internal, Fx_selection_exists_p)
15305 (Fx_selection_owner_p, Fx_get_selection_internal):
15306 Sync docs and argument specs with the xselect.c versions.
15308 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
15310 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

15328 2012-02-07 Chong Yidong <cyd@gnu.org>
15330 * buffer.c (Fbuffer_local_variables)
15331 (buffer_lisp_local_variables): Handle unbound vars correctly;
15332 don't let Qunbound leak into Lisp.
15334 2012-02-07 Glenn Morris <rgm@gnu.org>
15336 * image.c (Fimagemagick_types): Doc fix.
15338 * image.c (imagemagick-render-type): Change it from a lisp object
15339 to an integer. Move the doc here from the lisp manual.

15368 * keyboard.c (adjust_point_for_property): Don't position point
15369 before BEGV. (Bug#10696)
15371 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
15373 Handle overflow when computing char display width (Bug#9496).
15374 * character.c (char_width): Return EMACS_INT, not int.
15375 (char_width, c_string_width): Check for overflow when
15376 computing the width; this is possible now that individual
15377 characters can have unbounded width. Problem introduced
15378 by merge from Emacs 23 on 2012-01-19.
15380 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

15402 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
15404 (x_produce_glyphs): If the component of a composition is a null
15405 string, set it->pixel_width to 1 to avoid zero-width glyph.
15407 2012-02-01 Eli Zaretskii <eliz@gnu.org>
15409 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15410 first 2 arguments are identical. This makes inserting large
15411 output from a subprocess an order of magnitude faster on
15412 MS-Windows, where all sbrk'ed memory is always contiguous.
15414 2012-01-31 Glenn Morris <rgm@gnu.org>

15497 2012-01-11 Glenn Morris <rgm@gnu.org>
15499 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

15507 Update template values to be closer to their typical values these days.
15509 2012-01-09 Eli Zaretskii <eliz@gnu.org>

16027 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
16028 Otherwise, valgrind does not work on some platforms.
16029 Problem reported by Andreas Schwab in
16030 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
16031 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
16032 is set, removing the need for VIRT_ADDRESS_VARIES.
16033 (PURE_P): Use a more-efficient implementation that needs just one
16034 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
16035 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
16036 to 4 (xorl, subq, cmpq, setbe).
16037 * alloc.c (pure): Always extern now, since that's the
16038 VIRT_ADDR_VARIES behavior.
16039 (PURE_POINTER_P): Use a single comparison, not two, for
16040 consistency with the new puresize.h.
16041 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
16042 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
16043 Remove VIRT_ADDR_VARIES no longer needed.

16048 (erase_phys_cursor, update_window_cursor, show_mouse_face)
16049 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
16050 behave as if the cursor position were at the window margin.
16052 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
16053 and the cursor position is out of bounds, behave as if the cursor
16054 position were at the window margin. (Bug#10075)
16056 2011-11-18 Chong Yidong <cyd@gnu.org>
16058 * window.c (Fwindow_combination_limit): Make first argument

16077 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
16079 * xdisp.c (row_hash): New function, body extracted from
16080 compute_line_metrics.
16081 (compute_line_metrics): Call row_hash, instead of computing the
16084 * dispnew.c (verify_row_hash): Call row_hash for computing the
16085 hash code of a row, instead of duplicating code from xdisp.c.
16087 * dispextern.h (row_hash): Add prototype.
16089 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

16117 (Fsplit_window_internal, saved_window)
16118 (Fset_window_configuration, save_window_save): Rename all
16119 occurrences of window_nest to window_combination_limit.

16125 2011-11-14 Eli Zaretskii <eliz@gnu.org>
16127 * xdisp.c (display_line): Move the call to
16128 highlight_trailing_whitespace before the call to
16129 compute_line_metrics, since the latter needs to see the final
16130 faces of all the glyphs to compute ROW's hash value.
16131 Fixes assertion violations in row_equal_p. (Bug#10035)
16133 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
16135 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
16136 just return (bug#10044).
16138 2011-11-12 Eli Zaretskii <eliz@gnu.org>
16140 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
16141 with user-defined heap size. Bump the default size of the temacs
16142 heap to 27MB, to avoid memory warning when running temacs.

16145 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
16146 current_matrix and desired_matrix. (Bug#9990)
16147 (verify_row_hash) [XASSERTS]: New function.

16194 Avoid some portability problems by eschewing 'extern inline' functions.
16195 The trivial performance wins aren't worth the portability hassles; see
16196 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
16198 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

16272 (window_box_width, window_box_left, window_box_left_offset)
16273 (window_box_right, window_box_right_offset): Declare extern.
16274 Otherwise, these inline functions do not conform to C99 and
16275 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
16276 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
16277 * intervals.c (adjust_intervals_for_insertion)

16280 (static_offset_intervals): Remove.
16281 (offset_intervals): Rewrite using the old contents of
16282 static_offset_intervals. The old version didn't conform to C99

16437 HAVE_GTK3 (Bug#9869).
16439 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
16440 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
16442 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
16444 * xterm.c: Declare x_handle_net_wm_state to return int.
16445 (handle_one_xevent): Check if we are iconified but don't have
16446 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
16447 (get_current_wm_state): Return non-zero if not hidden,
16448 check for _NET_WM_STATE_HIDDEN (Bug#9893).
16449 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
16450 (x_handle_net_wm_state): Return what get_current_wm_state returns.
16451 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
16453 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
16455 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
16456 so that this new function doesn't get optimized away by a
16457 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
16459 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
16461 * frame.h (MOUSE_HL_INFO): Remove excess parens.
16463 2011-10-29 Eli Zaretskii <eliz@gnu.org>
16465 Fix the `xbytecode' command.
16466 * .gdbinit (xprintbytestr): New command.
16467 (xwhichsymbols): Rename from `which'; all callers changed.
16468 (xbytecode): Print the byte-code string as well.
16470 2011-10-29 Kim Storm <storm@cua.dk>
16472 * alloc.c (which_symbols): New function.
16474 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
16476 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
16479 2011-10-29 Glenn Morris <rgm@gnu.org>
16481 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
16482 Not clear what it was for, and it causes various bugs. (Bug#9839)
16484 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16486 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
16487 possible random value that matches one of those tested as
16488 condition to clear the mouse face.
16490 2011-10-28 Chong Yidong <cyd@gnu.org>
16492 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
16494 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
16496 * window.c (make_window): Initialize phys_cursor_on_p.
16498 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
16500 * lisp.h (struct Lisp_Symbol): Update comments.
16502 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
16504 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
16506 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16508 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
16509 <oslsachem@gmail.com> for helping to debug this.
16511 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
16512 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
16513 (g_b_init_get_glyph_outline_w): New static variables.
16514 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
16515 (GetGlyphOutlineW_Proc): New typedefs.
16516 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
16517 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
16519 (w32font_open_internal, compute_metrics):
16520 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16521 instead of calling the "wide" APIs directly.
16523 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
16525 * w32.h (syms_of_w32font): Add prototype.
16527 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16529 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
16530 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
16531 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
16532 (Fmove_to_window_line): Doc fix.
16534 2011-10-27 Chong Yidong <cyd@gnu.org>
16536 * process.c (make_process): Set gnutls_state to NULL.
16538 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
16539 non-NULL, regardless of GNUTLS_INITSTAGE.
16540 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
16541 an error. Set process slots as soon as we allocate them.
16543 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
16545 2011-10-27 Chong Yidong <cyd@gnu.org>
16547 * gnutls.c (emacs_gnutls_deinit): New function.
16548 Deallocate credentials structures as well as calling gnutls_deinit.
16549 (Fgnutls_deinit, Fgnutls_boot): Use it.
16551 * process.c (make_process): Initialize GnuTLS credentials to NULL.
16552 (deactivate_process): Call emacs_gnutls_deinit.
16554 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16556 * image.c (x_create_x_image_and_pixmap):
16557 * w32.c (sys_rename, w32_delayed_load):
16558 * w32font.c (fill_in_logfont):
16559 * w32reg.c (x_get_string_resource): Silence compiler warnings.
16561 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
16563 * w32fns.c (w32_default_color_map): New function,
16564 extracted from Fw32_default_color_map.
16565 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
16567 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
16569 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
16571 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
16573 * keyboard.c (test_undefined): New function (bug#9751).
16574 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
16576 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
16578 * sysdep.c (init_sys_modes): Fix the check for the controlling
16579 terminal (Bug#6649).
16581 2011-10-20 Eli Zaretskii <eliz@gnu.org>
16583 * dispextern.h (struct bidi_it): New member next_en_type.
16585 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16586 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16587 current character, check also for next_en_type being WEAK_EN.
16588 (bidi_resolve_weak): Don't enter the expensive loop if the current
16589 position is before next_en_pos. Record the bidi type of the first
16590 non-ET, non-BN character we find, in addition to its position.
16591 (bidi_level_of_next_char): Invalidate next_en_type when
16592 next_en_pos is over-stepped.
16594 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16596 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16597 * editfns.c: Rewrite current-time-zone so that it invokes
16598 the equivalent of (format-time-string "%Z") to get the time zone name.
16599 This fixes a bug when the time zone name contains characters that
16600 need converting from the system time locale to Emacs internal format.
16601 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16602 that patch fixed format-time-string to do the conversion, but
16603 I forgot to fix current-time-zone.
16604 (format_time_string): New function, containing most of
16605 what Fformat_time_string used to contain.
16606 (Fformat_time_string): Rewrite in terms of format_time_string.
16607 This doesn't change this function's behavior.
16608 (current-time-zone): Rewrite to use format_time_string.
16609 This fixes the bug reported by Michael Schierl in
16610 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16611 Jason Rumney's 2007-06-07 change worked around this bug, but
16613 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16615 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16617 * xdisp.c (start_display): If the character at POS is displayed
16618 via a display vector, reset IT->current.dpvec_index to zero.
16619 (try_window_reusing_current_matrix): If a line ends in a display
16620 vector or the next line starts in a display vector, continue
16621 redrawing the window even though the character position of
16622 start_row was reached.
16625 2011-10-18 Chong Yidong <cyd@gnu.org>
16627 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16628 with nobreak-char-display too.
16630 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16632 Fix part 3 of bug#9771.
16633 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16634 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16635 non-neutral characters if the current character is a paragraph
16636 separator (a.k.a. Newline). This avoids running the same
16637 expensive loop twice, once when we consume the preceding newline
16638 and the other time when the line actually needs to be displayed.
16639 Avoid the loop when we see neutrals on the base embedding level
16640 following a character whose directionality is the same as the
16641 paragraph's. This avoids running the expensive loop when a line
16642 ends in a long sequence of neutrals, like control characters.
16643 Add assertion against STRONG_AL type. Slightly rearrange code
16644 that determines the type of a neutral given the first non-neutral
16646 (bidi_level_of_next_char): Set next_en_pos to zero when
16647 invalidating its info.
16649 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16651 * xdisp.c (push_display_prop): Determine whether to record string
16652 or buffer position by IT->string, not by IT->method. Allow
16653 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16654 (move_it_vertically_backward): Don't look for character position
16655 immediately after the newline when in a continuation line.
16658 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16660 * window.c (coordinates_in_window): Rewrite and delabelize
16661 vertical border check. (Bug#5357) (Bug#9618)
16663 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16665 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16666 errors in XSetWindowBorder (bug#9310).
16668 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16670 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16671 avoid crash when xmalloc overrun checking is enabled.
16673 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16675 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16676 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16677 cursor motion with <left> and <right> arrow keys.
16679 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16680 some callers set that themselves.
16682 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16684 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16685 display string and the previous row comes from the same string and
16686 is empty. (Bug#9739) (Bug#9738)
16688 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16690 * doc.c (get_doc_string): Encode file name (bug#9735).
16692 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16694 * bidi.c (bidi_level_of_next_char):
16695 * xdisp.c (get_visually_first_element): Remove old incorrect
16696 comments regarding the Unicode Line Separator character.
16698 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16700 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16702 * alloc.c (Fgc_status): Do not access beyond zombies array
16703 boundary if nzombies > MAX_ZOMBIES.
16704 * alloc.c (dump_zombies): Add missing format specifier.
16706 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16708 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16709 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16711 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16712 Some packages use them to denote characters with modifiers.
16714 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16716 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16717 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16718 matching a pp-number. Rename parameter var to var1.
16720 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16722 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16724 2011-10-08 Glenn Morris <rgm@gnu.org>
16726 * callint.c (Fcall_interactively): Give a more explicit error for the
16727 'c' case with a non-character input. (Bug#8479)
16729 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16731 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16733 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16734 lines that are hscrolled on the left.
16736 * dispnew.c (buffer_posn_from_coords): Account for a possible
16737 presence of header-line. (Bug#4426)
16739 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16741 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16742 Don't advertise functionality which we discourage or doesn't work.
16744 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16746 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16747 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16748 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16749 this makes Emacs dump core during garbage collection on rare
16750 occasions. sizeof is obviously inferior to offsetof here, so
16751 stick with offsetof.
16752 (GC_POINTER_ALIGNMENT): New macro.
16753 (mark_memory): Omit 3rd (offset) arg; caller changed.
16754 Don't assume EMACS_INT alignment is the same as pointer alignment.
16756 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16758 * keyboard.c (read_key_sequence_remapped): New var.
16759 (read_key_sequence): Compute remapping in the right buffer.
16760 (command_loop_1): Use read_key_sequence's remapping directly.
16762 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16764 * dired.c (file_name_completion): Don't expand file name.
16765 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16766 before checking file name handler.
16768 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16769 they've been requested explicitly (bug#9591).
16771 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16773 * keymap.c (Fsingle_key_description): Use make_specified_string
16774 instead of build_string to build string from push_key_description.
16777 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16779 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16780 This fixes a Y2038 bug on 64-bit hosts.
16781 * buffer.c (reset_buffer):
16782 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16783 (Fclear_buffer_auto_save_failure):
16784 Use 0, not -1, to represent an unset failure time, since time_t
16785 might not be signed.
16787 Remove dependency on glibc malloc internals.
16788 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16789 Move back here from lisp.h, but with their new implementations.
16790 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16791 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16792 * charset.c (charset_table_init): New static var.
16793 (syms_of_charset): Use it instead of xmalloc. This removes a
16794 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16795 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16796 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16797 Move back to alloc.c.
16798 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16799 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16801 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16803 * nsterm.m (windowDidResize): Call x_set_window_size only when
16804 ns_in_resize is true. Otherwise set pixelwidth/height and
16805 call change_frame_size (Bug#9628).
16807 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16809 Port --enable-checking=all to Fedora 14 x86-64.
16810 * charset.c (syms_of_charset): Also account for glibc malloc's
16811 internal overhead when calculating the initial malloc maximum.
16813 Port --enable-checking=all to Fedora 14 x86.
16814 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16816 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16817 (overrun_check_realloc, overrun_check_free):
16818 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16819 That way, xmalloc returns a properly-aligned pointer even if
16820 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16821 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16822 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16823 into account when calculating the initial malloc maximum.
16824 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16825 Move here from alloc.c, so that charset.c can use it too.
16826 Properly align; the old code wasn't right for common 32-bit hosts
16827 when configured with --enable-checking=all.
16828 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16829 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16831 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16833 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16836 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16838 * xdisp.c (compute_display_string_end): If there's no display
16839 string at CHARPOS, return -1.
16841 * bidi.c (bidi_fetch_char): When compute_display_string_end
16842 returns a negative value, treat the character as a normal
16843 character not covered by a display string. (Bug#9624)
16845 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16847 * lread.c (Fread_from_string): Fix typo in docstring.
16849 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16851 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16852 newline, reseat the iterator instead of bidi-iterating there one
16853 character at a time. (Bug#9610)
16854 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16855 TO_CHARPOS if the bidi iterator is at base embedding level.
16857 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16859 * lread.c (readevalloop): Use correct code for NBSP.
16860 (read1): Likewise. (Bug#9608)
16862 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16864 * dbusbind.c (Fdbus_register_signal): When service is not
16865 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16867 2011-09-25 Glenn Morris <rgm@gnu.org>
16869 * buffer.c (truncate-lines): Doc fix.
16871 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16873 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16874 (Fset_window_next_buffers): Doc fix.
16876 2011-09-24 Glenn Morris <rgm@gnu.org>
16878 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16880 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16882 Fix minor problems found by static checking.
16883 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16884 * indent.c (Fvertical_motion): Fix == vs = typo.
16886 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16888 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16889 Default value is now t. Doc fix.
16891 * indent.c (Fvertical_motion): Compute and apply the overshoot
16892 logic when moving up, not only when moving down. Fix the
16893 confusing name and values of the it_overshoot_expected variable;
16894 logic changes accordingly. (Bug#9254) (Bug#9549)
16896 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16897 CHARPOS is covered by a display string which includes newlines.
16898 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16899 is covered by a display string with embedded newlines.
16901 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16903 * dbusbind.c (Fdbus_register_signal): Add match rule to
16904 Vdbus_registered_objects_table. (Bug#9581)
16905 (Fdbus_register_method, Vdbus_registered_objects_table):
16908 2011-09-24 Jim Meyering <meyering@redhat.com>
16910 do not ignore write error for any output size
16911 The previous change was incomplete.
16912 While it makes emacs --batch detect the vast majority of stdout
16913 write failures, errors were still ignored whenever the output size is
16914 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16915 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16916 && echo FAIL: ignored write error
16917 FAIL: ignored write error
16918 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16919 && echo FAIL: ignored write error
16920 FAIL: ignored write error
16921 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16923 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16925 * emacs.c (Fkill_emacs): In noninteractive mode exit
16926 non-successfully if a write error occurred on stdout. (Bug#9574)
16928 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16930 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16933 * dispextern.h (struct it): Update the comment documenting what
16936 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16938 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16939 a display string, extend search for cursor position to end of row.
16940 (find_row_edges): If the row ends in a newline from a display
16941 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16942 Handle the case of a display string with multiple newlines.
16943 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16944 non-empty line. Fixes confusing cursor motion with arrow keys at
16945 the beginning of a line that starts with whitespace.
16947 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16949 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16952 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16954 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16955 boolean (Bug#9154).
16957 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16959 * xdisp.c (display_line): Record maximum and minimum buffer
16960 positions even if no glyphs were produced (e.g., by a zero-width
16961 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16962 buffer positions that will be removed from the glyph row because
16964 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16965 column is beyond frame width: don't subtract 1 "pixel" when
16966 computing width of the stretch.
16967 (reseat_at_next_visible_line_start): Undo the change made on
16968 2011-09-17 that saved paragraph information and restored it after
16969 the call to `reseat'. (Bug#9545)
16971 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16973 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16974 and turn window cursor on if cleared (Bug#9415).
16976 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16978 * search.c (boyer_moore): Take unibyte characters from pattern
16979 literally. (Bug#9458)
16981 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16983 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16985 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16987 Fix minor problem found by static checking.
16988 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16989 initialized, to pacify gcc -Wuninitialized.
16991 * fileio.c: Report proper errno when syscall falls.
16992 (Finsert_file_contents): Save and restore errno,
16993 so that report_file_error outputs the correct diagnostic.
16994 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16996 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16998 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
17000 2011-09-17 Eli Zaretskii <eliz@gnu.org>
17002 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
17003 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
17005 2011-09-17 Eli Zaretskii <eliz@gnu.org>
17007 * xdisp.c (reseat_at_next_visible_line_start): Keep information
17008 about the current paragraph and restore it after the call to reseat.
17010 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
17011 (bidi_find_paragraph_start): Search back for paragraph beginning
17012 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
17013 (bidi_move_to_visually_next): Only trigger paragraph-related
17014 computations when the last character is a newline or at EOB, not
17015 just any NEUTRAL_B. (Bug#9470)
17017 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
17018 truncated lines if point is covered by a display string. (Bug#9524)
17020 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
17022 * xselect.c: Relax test for outgoing X longs (Bug#9498).
17023 (cons_to_x_long): New function.
17024 (lisp_data_to_selection_data): Use it. Correct the test for
17025 short-versus-long data; it was negated. Break out of vector
17026 loop, for efficiency, when a long datum is discovered.
17028 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
17030 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
17032 2011-09-16 Eli Zaretskii <eliz@gnu.org>
17034 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
17035 GCC PR/17406) by declaring this function with external scope.
17037 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
17039 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
17040 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
17042 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
17044 * editfns.c (Fformat): Correctly handle text properties on "%%".
17046 2011-09-15 Eli Zaretskii <eliz@gnu.org>
17048 * xterm.c (x_draw_composite_glyph_string_foreground):
17049 * w32term.c (x_draw_composite_glyph_string_foreground):
17050 * term.c (encode_terminal_code):
17051 * composite.c (composition_update_it, get_composition_id):
17052 * xdisp.c (get_next_display_element)
17053 (fill_composite_glyph_string): Add comments about special meaning
17054 of TAB characters in a composition.
17056 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
17058 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
17059 This occurs when processing a multibyte format.
17060 Problem reported by Wolfgang Jenker.
17062 2011-09-15 Johan Bockgård <bojohan@gnu.org>
17064 * xdisp.c (try_cursor_movement): Only check for exact match if
17065 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
17067 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
17069 Remove unused external symbols.
17070 * dispextern.h (calc_pixel_width_or_height): Remove decl.
17071 * xdisp.c (calc_pixel_width_or_height): Now static.
17072 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
17073 * indent.c (check_display_width):
17074 * w32term.c: Fix comment to match code.
17075 * xterm.c, xterm.h (x_catching_errors): Remove.
17077 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
17079 * xselect.c: Use signed conversions more consistently (Bug#9498).
17080 (selection_data_to_lisp_data): Assume incoming selection data are
17081 signed integers, not unsigned. This is to be consistent with
17082 outgoing selection data, which was modified to use signed integers
17083 in as part of the fix to Bug#9196 in response to Jan D.'s comment
17084 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
17085 expects long, not unsigned long.
17087 2011-09-14 Eli Zaretskii <eliz@gnu.org>
17089 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
17090 computation of loop end. Reported by Johan Bockgård
17093 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
17095 * frame.c (Fother_visible_frames_p): Function deleted.
17097 2011-09-12 Eli Zaretskii <eliz@gnu.org>
17099 * indent.c (compute_motion): Process display vector front to back
17100 rather than the other way around. (Bug#2496)
17102 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
17104 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
17106 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
17108 * minibuf.c (Fread_from_minibuffer): Doc fix.
17110 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17112 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
17113 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
17115 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
17117 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
17118 value for non-existent files.
17120 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17122 * fileio.c (Finsert_file_contents): If the file cannot be opened,
17123 set its "size" to -1. This will set the modtime_size field of
17124 the corresponding buffer to -1, which is what
17125 verify-visited-file-modtime expects for files that do not exist.
17128 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
17130 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
17132 * lisp.h: ... from here. push_key_description is no longer
17133 defined in keyboard.c, so its declaration should not be in
17134 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
17135 logically belongs with push_key_description.
17137 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
17139 * buffer.h: Include <sys/types.h> instead of <time.h>.
17140 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
17141 Problem reported by Herbert J. Skuhra.
17143 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
17145 * xml.c (parse_region): Make the parsing work for
17146 non-comment-starting XML files again (bug#9144).
17148 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
17150 * image.c (gif_load): Fix calculation of bottom and right corner.
17153 2011-09-10 Eli Zaretskii <eliz@gnu.org>
17155 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
17156 redisplay in small windows.
17158 2011-09-09 Eli Zaretskii <eliz@gnu.org>
17160 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
17162 2011-09-08 Martin Rudalics <rudalics@gmx.at>
17164 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
17165 Operate on live windows only.
17167 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
17169 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
17171 2011-09-07 Eli Zaretskii <eliz@gnu.org>
17173 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
17174 only under bidi iteration.
17176 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17178 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17180 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17182 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17183 Without this fix, the command to link temacs failed due to an
17184 undefined symbol __builtin_isnan. This is because
17185 /usr/include/iso/math_c99.h #defines isnan(x) to
17186 __builtin_isnan(x), but the bundled gcc, which identifies itself
17187 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17189 * floatfns.c (isnan): #undef, and then #define to a clone of
17191 (Fisnan): Always define, since it's always available now.
17192 (syms_of_floatfns): Always define isnan at the Lisp level.
17194 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17196 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17198 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17200 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17201 The previous code assumed that file offsets (off_t values) fit in
17202 EMACS_INT variables, which is not true on typical 32-bit hosts.
17203 The code messed up by falsely reporting buffer overflow in cases
17204 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17205 when "big" contains more than 2**29 bytes, even though this
17206 inserts just one byte and does not overflow the buffer.
17207 (Finsert_file_contents): Store file offsets as off_t
17208 values, not as EMACS_INT values. Check for overflow when
17209 converting between EMACS_INT and off_t. When checking for
17210 buffer overflow or for overlap, take the offsets into account.
17211 Don't use EMACS_INT for small values where int suffices.
17212 When checking for overlap, fix a typo: ZV was used where
17213 ZV_BYTE was intended.
17214 (Fwrite_region): Don't assume off_t fits into 'long'.
17215 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17217 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17219 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17221 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17223 sprintf-related integer and memory overflow issues (Bug#9412).
17225 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17226 (esprintf, exprintf, evxprintf): New functions.
17227 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17228 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17229 (modify_event_symbol): Do not assume that the length of
17230 name_alist_or_stem is safe to alloca and fits in int.
17231 (Fexecute_extended_command): Likewise for function name and binding.
17232 (Frecursion_depth): Wrap around reliably on integer overflow.
17233 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17234 since some callers pass EMACS_INT values.
17235 (Fsingle_key_description): Don't crash if symbol name contains more
17236 than MAX_ALLOCA bytes.
17237 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17238 (get_minibuffer): Arg is now EMACS_INT, not int.
17239 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17240 (esprintf, exprintf, evxprintf): New decls.
17241 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17243 * dbusbind.c (signature_cat): New function.
17244 (xd_signature, Fdbus_register_signal):
17245 Do not overrun buffer; instead, report string overflow.
17247 * dispnew.c (add_window_display_history): Don't overrun buffer.
17248 Truncate instead; this is OK since it's just a log.
17250 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17251 even if the time zone offset is outlandishly large.
17252 Don't mishandle offset == INT_MIN.
17254 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17255 when creating daemon; the previous buffer-overflow check was incorrect.
17257 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17258 which has the guts of the old verror function.
17260 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17261 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17263 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17264 (font_unparse_xlfd): Don't blindly alloca long strings.
17265 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17266 fits in int, when using sprintf. Use single snprintf to count
17267 length of string rather than counting it via multiple sprintfs;
17268 that's simpler and more reliable.
17269 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17270 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17271 sprintf, in case result does not fit in int.
17273 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17274 (fontset_from_font): Print it.
17276 * frame.c (tty_frame_count): Now printmax_t, not int.
17277 (make_terminal_frame, set_term_frame_name): Print it.
17278 (x_report_frame_params): In X, window IDs are unsigned long,
17279 not signed long, so print them as unsigned.
17280 (validate_x_resource_name): Check for implausibly long names,
17281 and don't assume name length fits in 'int'.
17282 (x_get_resource_string): Don't blindly alloca invocation name;
17283 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17286 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17287 (xg_check_special_colors, xg_set_geometry):
17288 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17290 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17291 Use esprintf, not sprintf, in case result does not fit in int.
17293 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17294 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17295 it as a large positive number.
17296 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17297 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17299 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17300 in case result does not fit in int.
17302 * print.c (float_to_string): Detect width overflow more reliably.
17303 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17304 buffer overrun. Don't assume list length fits in 'int'. Treat
17305 print length of 0 as 0, not as infinity; to be consistent with other
17306 uses of print length in this function. Don't overflow print length
17307 index. Don't assume hash table size fits in 'long', or that
17308 vectorlike size fits in 'unsigned long'.
17310 * process.c (make_process): Use printmax_t, not int, to format
17311 process-name gensyms.
17313 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17315 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17316 to avoid potential buffer overrun.
17318 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17319 if X resource line is longer than 512 bytes.
17321 * xfns.c (x_window): Make sprintf buffer a bit bigger
17322 to avoid potential buffer overrun.
17324 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17326 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17328 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17330 Integer overflow fixes for scrolling, etc.
17331 Without these, Emacs silently mishandles large integers sometimes.
17332 For example, "C-u 4294967297 M-x recenter" was treated as if
17333 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17335 * xdisp.c (try_window_id): Check Emacs fixnum range before
17336 converting to 'int'.
17338 * window.c (window_scroll_line_based, Frecenter):
17339 Check that an Emacs fixnum is in range before assigning it to 'int'.
17340 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17341 values converted from Emacs fixnums.
17342 (Frecenter): Don't wrap around a line count if it is out of 'int'
17343 range; instead, treat it as an extreme value.
17344 (Fset_window_configuration, compare_window_configurations):
17345 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17347 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17348 that can exceed INT_MAX. Check that EMACS_INT value is in range
17349 before assigning it to the (possibly-narrower) index.
17350 (match_limit): Don't assume that a fixnum can fit in 'int'.
17352 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17355 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17356 (Fvertical_motion): Don't wrap around LINES values that don't fit
17357 in 'int'. Instead, treat them as extreme values. This is good
17358 enough for windows, which can't have more than INT_MAX lines anyway.
17360 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17362 * Require libxml/parser.h to avoid compilation warning.
17364 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17366 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17367 since this reportedly can destroy thread storage.
17369 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17371 * syntax.c (find_defun_start): Update all cache variables if
17372 exiting early (Bug#9401).
17374 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17376 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17378 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17379 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17380 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17382 * term.c (tty_append_glyph): New function.
17383 (produce_stretch_glyph): Static function and its prototype deleted.
17385 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17388 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17390 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17391 when checking :margin (Bug#9390).
17392 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17393 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17394 so that the name doesn't mislead. All uses changed.
17396 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17398 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

17404 position beyond to_charpos, if we are scanning backwards.
17405 (move_it_vertically_backward): When DY == 0, make sure we get to
17406 the first character in the line after the newline.
17408 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17410 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17411 (ccl_driver): Do not generate an out-of-range pointer.
17412 (Fccl_execute_on_string): Remove unnecessary check for
17413 integer overflow, noted by Stefan Monnier in
17414 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17415 Remove a FIXME that didn't need fixing.
17416 Simplify the newly-introduced buffer reallocation code.
17418 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17420 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17422 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17424 Integer and memory overflow issues (Bug#9196).
17426 * doc.c (get_doc_string): Rework so that
17427 get_doc_string_buffer_size is the actual buffer size, rather than
17428 being 1 less than the actual buffer size; this makes xpalloc more
17431 * image.c (x_allocate_bitmap_record, cache_image):
17432 * xselect.c (Fx_register_dnd_atom):
17433 Simplify previous changes by using xpalloc.
17435 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17436 since either will do and ptrdiff_t is convenient with xpalloc.

17439 (struct charset_sort_data.priority): Now ptrdiff_t.
17440 (charset_compare): Don't overflow if priorities differ greatly.
17441 (Fsort_charsets): Don't assume list length fits in int.
17442 Check for size-calculation overflow when allocating sort data.
17443 (syms_of_charset): Allocate an initial charset table that is
17444 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17446 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17448 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17449 The actual value is always <= INT_MAX, and leaving it unsigned made
17450 overflow checking harder.
17452 * dispextern.h (struct glyph_matrix.rows_allocated)
17453 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17454 with xpalloc. The values are still always <= INT_MAX.
17456 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17458 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17459 (SAFE_NALLOCA): New macro.

17462 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17463 (set_cache_region, invalidate_region_cache)
17464 (revalidate_region_cache, know_region_cache, region_cache_forward)
17465 (region_cache_backward, pp_cache):
17466 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17467 so that ptrdiff_t * can be passed to xpalloc.
17468 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17469 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17470 (pp_cache): Don't assume cache_len fits in int.
17471 * region-cache.h: Adjust extern decls to match.
17473 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17474 EMACS_INT, since either will do, for xpalloc.
17476 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17477 (xnmalloc, xnrealloc, xpalloc): New functions.
17479 * bidi.c (bidi_shelve_header_size): New constant.
17480 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17481 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17483 * bidi.c (bidi_cache_shrink):
17484 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17486 Don't update size of array until after memory allocation succeeds,
17487 because xmalloc/xrealloc may not return.
17488 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17489 now that we have proper integer overflow checking.
17490 (record_overlay_string, overlay_strings): Catch overflows when
17491 calculating size of overlay_str_buf.
17493 * callproc.c (Fcall_process): Check for size overflow when
17494 calculating size of args2.
17495 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17496 Normally we prefer signed values, but sticking with ptrdiff_t would
17497 require adding more-complicated checks.
17499 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17500 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17501 Redo buffer-overflow calculations to avoid integer overflow.
17502 Add a FIXME comment where memory seems to be over-allocated.
17504 * character.c (Fstring): Check for size-calculation overflow.
17506 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17507 unnecessary integer overflow. Check for size overflow.
17508 (encode_coding_object): Don't update size until xmalloc succeeds.
17510 * composite.c (get_composition_id): Check for overflow in glyph
17511 length calculations.
17513 Integer and memory overflow fixes for display code.
17514 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17515 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

17530 Don't update size until allocation succeeds.
17531 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not

17537 (message_length): Now ptrdiff_t, not int.
17538 (Fmessage_box): Don't update size until allocation succeeds.
17539 Don't assume message length fits in int.
17540 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17542 * emacs.c (main): Do not reallocate argv, since there is a null at
17543 the end that can be overwritten, and this way there's no need to
17544 worry about size-calculation overflow.
17545 (sort_args): Check for size-calculation overflow.
17547 * eval.c (init_eval_once, grow_specpdl): Don't update size until
17549 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
17551 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
17552 (x_set_scroll_bar_width, x_figure_window_size):
17553 Check for integer overflow.
17554 (x_set_alpha): Do not assume XINT fits in int.
17556 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17557 This is for the members text_lines, text_cols, total_lines, total_cols,
17558 where the system imposes an 'int' limit.
17560 * fringe.c (Fdefine_fringe_bitmap):
17561 Don't update size until alloc works.
17563 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
17564 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
17566 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
17567 Check for size-calculation overflow.
17568 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17569 do, as we prefer signed integers.
17570 (id_to_widget.max_size, id_to_widget.used)
17571 (xg_store_widget_in_map, xg_remove_widget_from_map)
17572 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
17573 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
17574 Use and return ptrdiff_t, not int.
17575 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
17576 * gtkutil.h: Change prototypes to match the above.
17578 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
17579 are duplicate now that they've been promoted to lisp.h.
17580 (x_allocate_bitmap_record, x_alloc_image_color)
17581 (make_image_cache, cache_image, xpm_load):
17582 Don't update size until alloc is done.

17595 calculations. Don't update size until allocation succeeds.
17596 Redo calculations to avoid overflow.

17625 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17626 for command line length. Do not attempt to address one before the
17627 beginning of an array, as that's not portable.
17629 * term.c (max_frame_lines): Remove; unused.
17630 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
17632 (encode_terminal_code, calculate_costs): Check for size

17656 (Finternal_make_lisp_face, cache_face):
17657 Check for size calculation overflow.
17658 (cache_face): Treat size calculation overflows as if they were

17662 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17663 sizes, since they can exceed INT_MAX in size. Check for size

17667 (xg_select): Check for size calculation overflow.
17668 Don't update size until alloc done.
17670 * xrdb.c (get_environ_db): Don't assume path length fits in int,

17673 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17674 (X_LONG_MIN): New macros.
17675 Use them to make the following changes clearer.
17676 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17677 This change doesn't affect the value now, but it may help remind
17678 future maintainers not to raise the value too much later.
17679 (SELECTION_QUANTUM): Remove, replacing with ...
17680 (selection_quantum): ... new function, which avoids overflow.
17682 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17683 assumption that selection length fits in 'int'.

17695 (x_get_window_property, receive_incremental_selection)
17696 (lisp_data_to_selection_data, x_property_data_to_lisp):

17700 Don't store size until memory allocation succeeds.
17701 (x_get_window_property): Plug memory leak on memory exhaustion.
17702 Don't double-block input; malloc is safe here. Don't assume 2**34
17703 - 4 fits in unsigned long. Add an xassert to check
17704 XGetWindowProperty overflow. Be more careful about overflow
17705 calculations, and distinguish size from memory overflow better.
17706 (receive_incremental_selection): When tracing, don't assume
17707 unsigned int is less than INT_MAX.
17708 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
17709 harmful) conversions of unsigned short to int.
17710 (lisp_data_to_selection_data): Don't assume that integers
17711 in the range -65535 through -1 fit in an X unsigned short.
17712 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17713 result parameters unless successful. Rely on cons_to_unsigned
17714 to report problems with elements; the old code wasn't right anyway.
17715 (x_check_property_data): Check for int overflow; we cannot use
17716 a wider type due to X limits.
17717 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

17749 * lisp.h (hash_lookup, hash_put):
17750 * minibuf.c (Ftest_completion):
17751 Use ptrdiff_t for hash table indexes, not int (which is too
17752 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17753 32-bit --with-wide-int hosts).
17755 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17756 Add a FIXME comment about memory leaks.
17757 (syms_of_charset): Don't assume xmalloc returns.
17759 Don't assume that stated character widths fit in int.

17762 * indent.c (MULTIBYTE_BYTES_WIDTH):
17763 Use sanitize_char_width to avoid undefined and/or bad behavior
17764 with outlandish widths.
17765 * character.h (sanitize_tab_width): Rename from sanitize_width,
17766 now that we have two such functions. All uses changed.
17767 (sanitize_char_width): New inline function.
17769 Don't assume that tab-width fits in int.
17770 * character.h (sanitize_width): New inline function.
17771 (SANE_TAB_WIDTH): New macro.
17772 (ASCII_CHAR_WIDTH): Use it.

17777 * fileio.c: Integer overflow issues with file modes.
17778 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
17780 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
17781 Remove unreachable code.
17782 (read_hex, load_charset_map_from_file): Check for integer overflow.
17784 * xterm.c: Don't go over XClientMessageEvent limit.
17785 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17786 (x_send_scroll_bar_event): Likewise. Check that the size does not
17787 exceed limits imposed by XClientMessageEvent, as well as the usual
17788 ptrdiff_t and size_t limits.
17790 * keyboard.c: Overflow, signedness and related fixes.
17791 (make_lispy_movement): Use same integer type in forward decl
17792 that is used in the definition.
17793 (read_key_sequence, keyremap_step):
17794 Change bufsize argument back to int, undoing my 2011-03-30 change.
17795 We prefer signed types, and int is wide enough here.
17796 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17797 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17798 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17799 length, not size_t. Use ptrdiff_t for index, not int.
17800 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17801 possibility of integer overflow.
17803 Overflow, signedness and related fixes for images.
17805 * dispextern.h (struct it.stack[0].u.image.image_id)
17806 (struct_it.image_id, struct image.id, struct image_cache.size)
17807 (struct image_cache.used, struct image_cache.ref_count):

17813 * xdisp.c (calc_pixel_width_or_height):
17814 * xfns.c (image_cache_refcount):
17815 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
17816 on typical 64-bit hosts.
17818 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
17819 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

17822 when the callers expect that.
17823 (image_ascent): Redo ascent calculation to avoid int overflow.
17824 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17825 (lookup_image): Remove unnecessary tests.
17826 (xbm_image_p): Locals are now of int, not EMACS_INT,
17827 since parse_image_check makes sure they fit into int.
17828 (png_load, gif_load, svg_load_image):
17829 Prefer int to unsigned where either will do.
17830 (tiff_handler): New function, combining the cores of the
17831 old tiff_error_handler and tiff_warning_handler.
17832 This function is rewritten to use vsnprintf and thereby avoid
17833 stack buffer overflows. It uses only the features of vsnprintf
17834 that are common to both POSIX and native Microsoft.
17835 (tiff_error_handler, tiff_warning_handler): Use it.
17836 (tiff_load, gif_load, imagemagick_load_image):
17837 Don't assume :index value fits in 'int'.
17838 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17839 (imagemagick_load_image): Check that crop parameters fit into
17840 the integer types that MagickCropImage accepts. Don't assume
17841 Vimagemagick_render_type has a nonnegative value. Don't assume
17842 size_t fits in 'long'.
17843 (gs_load): Use printmax_t to print the widest integers possible.
17844 Check for integer overflow when computing image height and width.
17846 2011-08-26 Eli Zaretskii <eliz@gnu.org>
17848 * xdisp.c (redisplay_window): Don't force window start if point

17856 handle_single_display_spec, not just 1 or zero.
17857 (handle_single_display_spec): If the display spec is of the form
17858 `(space ...)', and specifies display in the text area, return 2
17860 (try_cursor_movement): Check for the need to scroll more
17861 accurately, and prefer exact match for point under bidi.
17862 Don't advance `row' beyond the last row of the window.
17864 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17865 into disp_prop; all users changed.
17867 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
17868 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
17869 for the text covered by the display property.

17879 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
17880 buffers, return left-to-right.
17881 (set_cursor_from_row): Consider candidate row a win if its glyph
17882 represents a newline and point is on that newline. Fixes cursor
17883 positioning on the newline at EOL of R2L text within L2R
17884 paragraph, and vice versa.
17885 (try_cursor_movement): Check continued rows, in addition to
17886 continuation rows. Fixes unwarranted scroll when point enters a
17887 continued line of R2L text within an L2R paragraph, or vice versa.
17888 (cursor_row_p): Consider the case of point being equal to
17889 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17890 from the end of a short line to the beginning of a continued line
17891 of R2L text within L2R paragraph.
17892 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
17893 composed characters.
17895 * bidi.c (bidi_check_type): Use xassert.
17896 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
17899 2011-08-23 Eli Zaretskii <eliz@gnu.org>

17906 * nsfont.m (ns_otf_to_script): Fix typo.
17908 2011-08-22 Kenichi Handa <handa@m17n.org>
17910 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17911 extra slot even if the purpose is char-code-property-table.
17913 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17915 * xdisp.c (redisplay_window): When computing centering_position,
17916 account for the height of the header line. (Bug#8874)
17918 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17919 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17920 candidate is selected by the mouse, and that candidate has a
17921 composed character under the mouse.
17923 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17924 coordinates reported by pos-visible-in-window-p for a composed
17925 character in column zero.
17927 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17929 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17931 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17933 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17934 consider it a hit if to_charpos is anywhere in the range of the
17935 composed buffer positions.
17937 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17939 * image.c (gif_load): Don't assume that each subimage has the same
17940 dimensions as the base image. Handle disposal method that is
17941 "undefined" by the gif spec (Bug#9335).
17943 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17945 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17948 2011-08-19 Eli Zaretskii <eliz@gnu.org>
17950 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17951 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17952 from an Org mode buffer to a Speedbar frame.
17954 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17955 a composition, take its buffer position from IT->cmp_it.charpos.
17956 Fixes cursor positioning at the beginning of a line that begins
17957 with a composed character.
17959 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17961 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17962 character bidirectional type, use STRONG_L instead. Fixes crashes
17963 in a buffer produced by `describe-categories'.
17965 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17966 members before the level stack, so they would be saved and
17967 restored when copying iterator state. Fixes incorrect reordering
17968 around TABs covered by display properties.
17970 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17972 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17985 2011-08-16 Ken Brown <kbrown@cornell.edu>
17987 * gmalloc.c: Expand comment.
17989 2011-08-16 Eli Zaretskii <eliz@gnu.org>

18042 * xdisp.c (move_it_in_display_line_to): Don't invoke
18043 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
18044 ppos_it. Fixes vertical cursor motion when line beginning is
18045 covered by an image. (Bug#9296)
18047 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
18049 * nsterm.h (ns_run_ascript): Declare.

18053 (ns_run_ascript): New function.
18054 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
18055 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
18056 the event loop. Get status from as_status (Bug#7276).
18058 * nsterm.m (sendEvent): If event is NSApplicationDefined and
18059 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
18060 the event loop (Bug#7276).
18062 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

18086 (Fnetwork_interface_list): Allocate in increments of bytes instead
18087 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
18088 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
18090 (struct ifflag_def): notrailers is smart on OSX.
18091 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
18092 Get hardware address with getifaddrs if available.
18094 2011-08-12 Eli Zaretskii <eliz@gnu.org>
18096 * xdisp.c (iterate_out_of_display_property): xassert that
18097 IT->position is set to within IT->object's boundaries. Break from

18100 Set IT->current to match the bidi iterator unconditionally.
18101 (push_display_prop): Allow GET_FROM_STRING as IT->method on
18102 entry. Force push_it to save on the stack the current
18103 buffer/string position, to be restored by pop_it. Fix flags in
18104 the iterator structure wrt the object coming from a display
18105 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
18106 properties. (Bug#9284)
18108 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
18110 * fontset.c (fontset_get_font_group): Add proper type checks.

18138 restore_point_unwind (Bug#5984).
18140 2011-08-07 Juri Linkov <juri@jurta.org>
18142 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

18147 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
18148 display property strides EOL and includes a newline, as in
18149 longlines-mode. (Bug#9254)
18150 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
18151 word-wrap under bidirectional display. (Bug#9224)
18153 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
18154 is non-zero, even if the data buffer is NULL. Fixes a crash in
18155 vertical-motion with longlines-mode. (Bug#9254)
18157 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18159 * bidi.c <bidi_cache_total_alloc>: Now static.

18162 * xdisp.c (display_line): Release buffer allocated for shelved bidi
18165 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
18166 amount allocated this far in `bidi_cache_total_alloc'.
18167 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
18168 non-zero, only free the data buffer without restoring the cache
18169 contents. All callers changed.
18171 * dispextern.h (bidi_unshelve_cache): Update prototype.
18173 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
18174 (move_it_in_display_line, move_it_to)
18175 (move_it_vertically_backward, move_it_by_lines): Replace the call
18176 to xfree to an equivalent call to bidi_unshelve_cache.
18177 (move_it_in_display_line_to): Fix logic of returning
18178 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
18180 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18182 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

18233 * bidi.c (bidi_fetch_char): Accept an additional argument
18234 DISP_PROP_P, and pass it to compute_display_string_pos.
18235 Only handle text covered by a display string if DISP_PROP_P is returned
18236 non-zero. All callers of bidi_fetch_char changed.
18238 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
18240 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
18242 2010-12-03 Don March <don@ohspite.net>
18244 * keymap.c (Fdefine_key): Fix non-prefix key error message when
18245 last character M-[char] is translated to ESC [char] (bug#7541).
18247 2011-08-02 Kenichi Handa <handa@m17n.org>
18249 * lisp.h (uniprop_table): Extern it.
18251 * chartab.c (uniprop_table): Make it non-static.
18253 2011-08-01 Eli Zaretskii <eliz@gnu.org>
18255 * xdisp.c (forward_to_next_line_start): Accept additional argument
18256 BIDI_IT_PREV, and store into it the state of the bidi iterator had
18258 (reseat_at_next_visible_line_start): Use the bidi iterator state
18259 returned by forward_to_next_line_start to restore the state of
18260 it->bidi_it after backing up to previous newline. (Bug#9212)
18262 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
18264 * regex.c (re_comp): Protoize.
18265 (re_exec): Fix return type.
18266 (regexec): Fix type of `ret'. (Bug#9203)
18268 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18270 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
18271 This is needed if max-image-size is a floating-point number.
18273 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18275 * print.c (print_object): Print empty symbol as ##.
18277 * lread.c (read1): Read ## as empty symbol.
18279 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18281 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
18282 setting frame foreground color (Bug#9175).
18283 (x_set_background_color): Likewise.
18285 * nsmenu.m (-setText): Size tooltip dimensions precisely to
18286 contents (Bug#9176).
18287 (EmacsTooltip -init): Remove bezels and add shadows to
18290 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
18291 or scroll bar (Bug#8470).
18293 * nsfont.m (nsfont_open): Remove assignment to voffset and
18294 unnecessary vars hshink, expand, hd, full_height, min_height.
18295 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
18297 * nsterm.h (nsfont_info): Remove voffset field.
18299 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18301 Implement strike-through and overline on NextStep (Bug#8863).
18303 * nsfont.m (nsfont_open): Use underline position provided by font,
18304 instead of hard-coded value of 2.
18305 (nsfont_draw): Call ns_draw_text_decoration instead.
18307 * nsterm.h: Add declaration for ns_draw_text_decoration.
18309 * nsterm.m (ns_draw_text_decoration): New function for drawing
18310 underline, overline, and strike-through.
18311 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
18312 ns_draw_text_decoration. Change treatment of cursor drawing to
18313 accommodate underlining, etc.
18315 2011-07-28 Eli Zaretskii <eliz@gnu.org>
18317 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
18320 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18322 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18323 Without this fix, if a signal arrives just after memory fills up,
18324 'malloc' might be invoked reentrantly.
18326 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18327 In other words, assume that every image size is allowed, on non-X
18328 hosts. This assumption is probably wrong, but it lets Emacs compile.
18330 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18332 * regex.c (re_iswctype): Convert return values to boolean.
18334 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
18336 * xdisp.c (compute_display_string_pos): Don't use cached display
18337 string position if the buffer had its restriction changed.
18340 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18342 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18344 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18346 Integer signedness and overflow and related fixes. (Bug#9079)
18348 * bidi.c: Integer size and overflow fixes.
18349 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18350 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18351 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18352 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18353 (bidi_find_other_level_edge):
18354 Use ptrdiff_t instead of EMACS_INT where either will do.
18355 This works better on 32-bit hosts configured --with-wide-int.
18356 (bidi_cache_ensure_space): Check for size-calculation overflow.
18357 Use % rather than repeated addition, for better worst-case speed.
18358 Don't set bidi_cache_size until after xrealloc returns, because it
18360 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18361 (bidi_cache_ensure_space): Also check that the bidi cache size
18362 does not exceed that of the largest Lisp string or buffer. See Eli
18363 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18365 * alloc.c (__malloc_size_t): Remove.
18366 All uses replaced by size_t. See Andreas Schwab's note
18367 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18369 * image.c: Improve checking for integer overflow.
18370 (check_image_size): Assume that f is nonnull, since
18371 it is always nonnull in practice. This is one less thing to
18372 worry about when checking for integer overflow later.
18373 (x_check_image_size): New function, which checks for integer
18374 overflow issues inside X.
18375 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18376 This removes the need for a memory_full check.
18377 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18378 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18379 (xbm_read_bitmap_data): Change locals back to 'int', since
18380 their values must fit in 'int'.
18381 (xpm_load_image, png_load, tiff_load):
18382 Invoke x_create_x_image_and_pixmap earlier,
18383 to avoid much needless work if the image is too large.
18384 (tiff_load): Treat overly large images as if
18385 x_create_x_image_and_pixmap failed, not as malloc failures.
18386 (gs_load): Use x_check_image_size.
18388 * gtkutil.c: Omit integer casts.
18389 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18390 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18392 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18394 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18395 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18396 would wrongly return t on a 64-bit host.
18398 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18399 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18400 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18401 and therefore cause GCC to emit a bogus diagnostic in some cases.
18403 * image.c: Integer signedness and overflow and related fixes.
18404 This is not an exhaustive set of fixes, but it's time to
18405 record what I've got.
18406 (lookup_pixel_color, check_image_size): Remove redundant decls.
18407 (check_image_size): Don't assume that arbitrary EMACS_INT values
18408 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18409 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18410 (tiff_load, imagemagick_load_image):
18411 Check for overflow in size calculations.
18412 (x_create_x_image_and_pixmap): Remove unnecessary test for
18413 xmalloc returning NULL; that can't happen.
18414 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18415 (xpm_color_bucket): Use better integer hashing function.
18416 (xpm_cache_color): Don't possibly over-allocate memory.
18417 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18418 (gif_memory_source):
18419 Use ptrdiff_t, not int or size_t, to record sizes.
18420 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18421 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18422 either works, as we prefer signed integers.
18423 (tiff_read_from_memory, tiff_write_from_memory):
18424 Return tsize_t, not size_t, since that's what the TIFF API wants.
18425 (tiff_read_from_memory): Don't fail simply because the read would
18426 go past EOF; instead, return a short read.
18427 (tiff_load): Omit no-longer-needed casts.
18428 (Fimagemagick_types): Don't assume size fits into 'int'.
18430 Improve hashing quality when configured --with-wide-int.
18431 * fns.c (hash_string): New function, taken from sxhash_string.
18432 Do not discard information about ASCII character case; this
18433 discarding is no longer needed.
18434 (sxhash-string): Use it. Change sig to match it. Caller changed.
18435 * lisp.h: Declare it.
18436 * lread.c (hash_string): Remove, since we now use fns.c's version.
18437 The fns.c version returns a wider integer if --with-wide-int is
18438 specified, so this should help the quality of the hashing a bit.
18440 * emacs.c: Integer overflow minor fix.
18441 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18442 Define only if GNU_LINUX.
18443 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18445 * dispnew.c: Integer signedness and overflow fixes.
18446 Remove unnecessary forward decls, that were a maintenance hassle.
18447 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18449 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18450 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18451 (prepare_desired_row, line_draw_cost):
18452 Use int, not unsigned, where either works.
18453 (save_current_matrix, restore_current_matrix):
18454 Use ptrdiff_t, not size_t, where either works.
18455 (init_display): Check for overflow more accurately, and without
18456 relying on undefined behavior.
18458 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18459 Remove, replacing with the new symbols in lisp.h. All uses changed.
18460 * fileio.c (make_temp_name):
18461 * filelock.c (lock_file_1, lock_file):
18462 * xdisp.c (message_dolog):
18463 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18464 Use pMd etc. instead.
18465 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18466 replacing the pWIDE etc. symbols removed from editfns.c.
18468 * keyboard.h (num_input_events): Now uintmax_t.
18469 This is (very slightly) less likely to mess up due to wraparound.
18472 * buffer.c: Integer signedness fixes.
18473 (alloc_buffer_text, enlarge_buffer_text):
18474 Use ptrdiff_t rather than size_t when either will do, as we prefer
18477 * alloc.c: Integer signedness and overflow fixes.
18478 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18479 (__malloc_size_t): Default to size_t, not to int.
18480 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18481 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18482 Prefer ptrdiff_t to size_t when either would do, as we prefer
18484 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18485 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18486 Now const. Initialize with values that are in range even if char
18488 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18489 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18490 These functions do the right thing with sizes > 2**32.
18491 (check_depth): Now ptrdiff_t, not int.
18492 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18493 Adjust to new way of storing sizes. Check for size overflow bugs
18495 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18496 slightly wrong anyway, as it missed one instance of
18497 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18498 (refill_memory_reserve): Omit needless cast to size_t.
18499 (mark_object_loop_halt): Mark as externally visible.
18501 * xselect.c: Integer signedness and overflow fixes.
18502 (Fx_register_dnd_atom, x_handle_dnd_message):
18503 Use ptrdiff_t, not size_t, since we prefer signed.
18504 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18505 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18506 x_dnd_atoms_size and x_dnd_atoms_length.
18508 * doprnt.c: Prefer signed to unsigned when either works.
18510 * doprnt.c (doprnt):
18512 * xdisp.c (vmessage):
18513 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18514 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18515 prefer signed arithmetic to avoid comparison confusion.
18516 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18517 but is a bit tricky.
18519 Assume freestanding C89 headers, string.h, stdlib.h.
18520 * data.c, doprnt.c, floatfns.c, print.c:
18521 Include float.h unconditionally.
18522 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18523 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18524 * regex.c: Likewise for stddef.h, string.h.
18525 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18526 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18527 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18528 (STDC_HEADERS): Remove obsolete defines.
18529 * sysdep.c: Include limits.h unconditionally.
18531 Assume support for memcmp, memcpy, memmove, memset.
18532 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18533 * regex.c (memcmp, memcpy):
18534 Remove; we assume C89 now.
18536 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18537 (__malloc_safe_bcopy): Remove; no longer needed.
18539 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18540 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18541 well either way, and we prefer signed to unsigned.
18543 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18545 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18546 closes the connection while we're reading (bug#9182).
18548 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18550 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18551 are specified (Bug#9168).
18553 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18555 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18556 Found by GCC static checking and --with-wide-int on a 32-bit host.
18558 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18560 * xdisp.c (compute_display_string_pos): Fix logic of caching
18561 previous display string position. Initialize cached_prev_pos to
18562 -1. Fixes slow-down at the beginning of a buffer.
18564 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18566 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18567 for attrs[LFACE_FONTSET_INDEX].
18569 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18571 * xml.c (parse_region): Remove unused local
18572 that was recently introduced.
18574 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18576 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18577 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18579 * xdisp.c (move_it_in_display_line_to): Record the best matching
18580 position for TO_CHARPOS while scanning the line, and restore it on
18581 exit if none of the characters scanned was an exact match.
18582 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18583 when exact match is impossible due to invisible text, and the
18584 lines are truncated.
18586 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18588 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18591 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18593 Fix a significant slow-down of cursor motion with C-n, C-p,
18594 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18595 auto-repeat under bidi redisplay in fontified buffers.
18596 * xdisp.c (compute_stop_pos_backwards): New function.
18597 (next_element_from_buffer): Call compute_stop_pos_backwards to
18598 find a suitable prev_stop when we find ourselves before
18600 (reseat): Don't look for prev_stop, as that could mean a very long
18602 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18603 <cached_disp_overlay_modiff>: Cache for last found display string
18605 (compute_display_string_pos): Return the cached position if asked
18606 about the same buffer in the same area of character positions, and
18607 the buffer wasn't changed since the time the display string
18608 position was cached.
18610 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18612 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18613 is an integer, which is important for empty lines. (Bug#9149)
18615 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18617 * frame.c (Fmodify_frame_parameters): In tty case, update the
18618 default face if necessary (Bug#4238).
18620 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18622 * editfns.c (Fstring_to_char): No need to explain what a character
18623 is in the docstring (Bug#6576).
18625 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18627 * xml.c (parse_region): Make sure we always return a tree.
18629 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18631 * xml.c (parse_region): If a document contains only comments,
18634 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18636 * xml.c (make_dom): Return comments, too.
18638 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18641 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18642 and the surrounding thread.
18643 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18644 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18645 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18647 * s/openbsd.h (BROKEN_SIGIO): Define.
18648 * unexelf.c (unexec) [__OpenBSD__]:
18649 Don't update the .mdebug section of the Alpha COFF symbol table.
18651 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18653 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18656 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18658 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18659 This fixes some race conditions on the permissions of any newly
18662 * alloc.c (valid_pointer_p): Use pipe, not open.
18663 This fixes some permissions issues when debugging.
18665 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18666 If fchown fails to set both uid and gid, try to set just gid,
18667 as that is sometimes allowed. Adjust the file's mode to eliminate
18668 setuid or setgid bits that are inappropriate if fchown fails.
18670 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18672 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18673 to compare Lisp_Objects.
18674 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18675 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18676 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18678 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>

18688 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18689 This works around a problem with the previous change to Fcopy_file.
18690 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18691 and without this change, GCC might complain about discarding
18692 fchown's return value.
18694 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18696 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

18719 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18721 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18722 quotes the next character, and doesn't affect other longer
18723 sequences (bug#8935).
18725 * lread.c (syms_of_lread): Clarify that is isn't only
18726 `eval-buffer' and `eval-defun' that's affected by

18737 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18738 (elsz): Now a signed constant, not a size_t var. We prefer signed
18739 types to unsigned, to avoid integer comparison confusion. Without
18740 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18741 "cannot optimize loop, the loop counter may overflow", a symptom
18743 * indent.c (Fvertical_motion): Mark locals as initialized.
18744 * xdisp.c (reseat_to_string): Fix pointer signedness issue.

18790 the iterator is before prev_stop.
18791 (init_iterator): Initialize bidi_p from the default value of

18833 iterator by calling bidi_pop_it same number of times.
18834 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18835 and we are bidi-iterating, don't decrement the iterator position;
18836 instead, set the first_elt flag in the bidi iterator, to produce
18838 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18839 (push_display_prop): xassert that we are iterating a buffer.

18843 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18844 correctly. Don't assume unibyte strings are not bidi-reordered.

19271 if Emacs is configured with --with-wide-int.
19272 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
19273 New macros, used in the buffer.c change.

19309 Random fixes. E.g., (random) never returned negative values.
19310 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19311 subseconds part to the entropy, as that's a bit more random.
19312 Prefer signed to unsigned, since the signedness doesn't matter and
19313 in general we prefer signed. When given a limit, use a
19314 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19315 latter isn't right if USE_2_TAGS_FOR_INTS.
19316 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19317 not 0..VALMASK. Don't discard "excess" bits that random () returns.

19329 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19330 This is more efficient than Ffile_directory_p and avoids a minor race.

19334 * buffer.c (Foverlay_put): Say what the return value is
19337 * fileio.c (barf_or_query_if_file_exists): Check first if the file

19341 error be more correct.
19343 * fns.c (Frequire): Remove the mention of the .gz files, since
19344 that's installation-specific, but keep the mention of

19360 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19361 Also (re)move comments that are misplaced or no longer relevant.

19390 * lread.c (syms_of_lread): Mention single symbols defined by
19391 `defvar' or `defconst' (bug#7154).

19462 * eval.c (struct backtrace): Simplify and port the data structure.
19463 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19464 signed bit field, as this assumption is not portable and it makes
19465 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19466 "char debug_on_exit : 1" as this is not portable either; instead,
19467 use the portable "unsigned int debug_on_exit : 1". Remove unused
19468 member evalargs. Remove obsolete comments about cc bombing out.
19470 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19558 * process.c (wait_reading_process_output): Bypass select if
19559 waiting for a cell while ignoring keyboard input, and input is
19560 pending. Suggested by Jan Djärv (Bug#8869).
19562 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
19564 Use gnulib's dup2 module instead of rolling our own.
19565 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
19567 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19569 * dispnew.c (scrolling_window): Before scrolling, turn off a

19632 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
19634 Integer and buffer overflow fixes (Bug#8873).
19636 * print.c (printchar, strout): Check for string overflow.
19637 (PRINTPREPARE, printchar, strout):
19638 Don't set size unless allocation succeeds.
19640 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19641 for sizes. Check for string overflow more accurately.
19642 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
19644 * macros.c: Integer and buffer overflow fixes.
19645 * keyboard.h (struct keyboard.kbd_macro_bufsize):
19646 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

19649 Check for size-calculation overflow.
19650 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
19652 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
19654 * lread.c: Integer overflow fixes.
19655 (read_integer): Radix is now EMACS_INT, not int,
19656 to improve quality of diagnostics for out-of-range radices.
19657 Calculate buffer size correctly for out-of-range radices.
19658 (read1): Check for integer overflow in radices, and in
19659 read-circle numbers.
19660 (read_escape): Avoid int overflow.
19661 (Fload, openp, read_buffer_size, read1)
19662 (substitute_object_recurse, read_vector, read_list, map_obarray):

19678 2011-06-22 Leo Liu <sdl.web@gmail.com>
19680 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
19681 Move to minibuffer.el.
19683 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19685 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19686 The following patches are for when GLYPH_DEBUG && !XASSERT.
19687 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19688 * dispnew.c (flush_stdout):
19689 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19690 Mark as externally visible.
19691 * dispnew.c (check_window_matrix_pointers): Now static.
19692 * dispnew.c (window_to_frame_vpos):
19693 * xfns.c (unwind_create_frame):
19694 * xterm.c (x_check_font): Remove unused local.
19695 * scroll.c (CHECK_BOUNDS):
19696 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19697 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19698 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19699 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19700 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19702 (debug_method_add): Use va_list and vsprintf rather than relying
19703 on undefined behavior with wrong number of arguments.
19704 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19705 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19706 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19707 since we're not interested in debugging glyphs with old libraries.
19708 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19709 GCC 4.6.0's static checking.
19711 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19713 Integer overflow and signedness fixes (Bug#8873).

19724 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19725 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19727 * xfaces.c (load_pixmap):

19729 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19730 (.bitmaps_last, struct x_output.icon_bitmap):
19731 Use ptrdiff_t, not int, for bitmap indexes.
19732 (x_allocate_bitmap_record): Check for size overflow.
19733 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19735 Use ptrdiff_t, not int, for overlay counts.
19736 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19737 * editfns.c (overlays_around, get_pos_property):
19738 * textprop.c (get_char_property_and_overlay):
19739 * xdisp.c (next_overlay_change, note_mouse_highlight):
19740 * xfaces.c (face_at_buffer_position):
19741 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19742 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19743 (Fnext_overlay_change, Fprevious_overlay_change)
19744 (mouse_face_overlay_overlaps, Foverlays_in):
19745 Use ptrdiff_t, not int, for sizes.
19746 (overlays_at, overlays_in): Check for size-calculation overflow.
19748 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19750 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19751 (x_session_initialize): Do not assume string length fits in int.
19753 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19754 This is unlikely, but can occur if DPI is outlandish.
19756 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19757 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19759 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19760 * xrdb.c (magic_file_p, search_magic_path):
19761 Omit last arg SUFFIX; it was always 0. All callers changed.
19762 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19764 * xfont.c (xfont_match): Avoid need for strlen.
19766 * xfns.c: Don't assume strlen fits in int.
19767 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19769 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19770 not unsigned long, as we prefer signed integers. All callers changed.
19771 Detect integer overflow in repeat count.
19772 (message_dolog): Don't assume print length fits in 39 bytes.
19773 (display_mode_element): Don't assume strlen fits in int.
19775 * termcap.c: Don't assume sizes fit in int and never overflow.
19776 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19777 (gobble_line): Check for size-calculation overflow.
19779 * minibuf.c (Fread_buffer):
19780 * lread.c (intern, intern_c_string):
19781 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

19785 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19787 * font.c: Don't assume string length fits in int.
19788 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19789 Use ptrdiff_t, not int.
19790 (font_intern_prop): Don't assume string length fits in int.
19791 Don't assume integer property fits in fixnum.
19792 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19794 * filelock.c: Fix some buffer overrun and integer overflow issues.
19795 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19796 Reformulate so as not to need the command string.
19797 Invoke gzip -cd rather than gunzip, as it's more portable.
19798 (lock_info_type, lock_file_1, lock_file):
19799 Don't assume pid_t and time_t fit in unsigned long.
19800 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19801 (current_lock_owner): Prefer signed type for sizes.
19802 Use memcpy, not strncpy, where memcpy is what is really wanted.
19803 Don't assume (via atoi) that time_t and pid_t fit in int.
19804 Check for time_t and/or pid_t out of range, e.g., via a network share.
19805 Don't alloca where an auto var works fine.
19807 * fileio.c: Fix some integer overflow issues.
19808 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19809 Don't assume string length fits in int.
19810 (directory_file_name): Don't assume string length fits in long.
19811 (make_temp_name): Don't assume pid fits in int, or that its print
19812 length is less than 20.
19814 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19816 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19818 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19820 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19821 We prefer signed integers, even for size calculations.
19823 * emacs.c: Don't assume string length fits in 'int'.
19824 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19825 (main): Don't invoke strlen when not needed.
19827 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19828 (XD_DEBUG_MESSAGE): Don't waste a byte.
19830 * callproc.c (getenv_internal_1, getenv_internal)
19831 (Fgetenv_internal):
19832 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19834 * lread.c (invalid_syntax): Omit length argument.
19835 All uses changed. This doesn't fix a bug, but it simplifies the
19836 code away from its former Hollerith-constant appearance, and it's
19837 one less 'int' to worry about when looking at integer-overflow issues.
19838 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19840 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19841 This didn't break anything, but it didn't help either.
19842 It's confusing to put a bogus integer in a place where the actual
19843 value does not matter.
19844 (LIST_END_P): Remove unused macro and its bogus comment.
19845 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19847 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19848 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19850 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19851 We prefer signed types, and the value cannot exceed the EMACS_INT
19852 range anyway (because otherwise the length would not be representable).
19853 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19854 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19855 This avoids a GCC warning when WIDE_EMACS_INT.
19857 * indent.c (sane_tab_width): New function.
19858 (current_column, scan_for_column, Findent_to, position_indentation)
19859 (compute_motion): Use it. This is just for clarity.
19860 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19862 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

19865 * composite.c (composition_gstring_put_cache):
19866 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19868 * editfns.c, insdel.c:
19869 Omit unnecessary forward decls, to simplify future changes.
19871 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19873 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19875 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19876 Use much-faster test for byte-length change.
19877 Don't assume string byte-length fits in 'int'.
19878 Check that character arg fits in 'int'.
19879 (mapcar1): Declare byte as byte, for clarity.
19881 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19883 * fns.c (concat): Catch string overflow earlier.
19884 Do not rely on integer wraparound.
19886 * dispextern.h (struct it.overlay_strings_charpos)
19887 (struct it.selective): Now EMACS_INT, not int.
19888 * xdisp.c (forward_to_next_line_start)
19889 (back_to_previous_visible_line_start)
19890 (reseat_at_next_visible_line_start, next_element_from_buffer):
19891 Don't arbitrarily truncate the value of 'selective' to int.
19893 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19895 * composite.c: Don't truncate sizes to 'int'.
19896 (composition_gstring_p, composition_reseat_it)
19897 (composition_adjust_point): Use EMACS_INT, not int.
19898 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19899 not EMACS_UINT, for indexes.
19901 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19903 * buffer.c: Include <verify.h>.
19904 (struct sortvec.priority, struct sortstr.priority):
19905 Now EMACS_INT, not int.
19906 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19907 (struct sortstr.size, record_overlay_string)
19908 (struct sortstrlist.size, struct sortlist.used):
19909 Don't truncate size to int.
19910 (record_overlay_string): Check for size-calculation overflow.
19911 (init_buffer_once): Check at compile-time, not run-time.
19913 2011-06-22 Jim Meyering <meyering@redhat.com>
19915 Don't leak an XBM-image-sized buffer
19916 * image.c (xbm_load): Free the image buffer after using it.
19918 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19921 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19922 that Sun C diagnosed.
19923 * fns.c (secure_hash): Fix pointer signedness issue.
19924 * intervals.c (static_offset_intervals): New function.
19925 (offset_intervals): Use it.
19927 2011-06-21 Leo Liu <sdl.web@gmail.com>
19930 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19933 * fns.c (secure_hash): Rename from crypto_hash_function and change
19934 the first arg to accept symbols.
19935 (Fsecure_hash): New primitive.
19936 (syms_of_fns): New symbols.
19938 2011-06-20 Deniz Dogan <deniz@dogan.se>
19940 * process.c (Fset_process_buffer): Clarify return value in
19943 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19945 * dispnew.c (add_window_display_history): Use BVAR.
19947 * xdisp.c (debug_method_add): Use BVAR.
19948 (check_window_end, dump_glyph_matrix, dump_glyph)
19949 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19951 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19954 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19955 check till after the cache is created in init_frame_faces.
19957 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19959 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19961 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19963 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19964 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19965 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19967 Improve buffer-overflow checking (Bug#8873).
19968 * fileio.c (Finsert_file_contents):
19969 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19970 Remove the old (too-loose) buffer overflow checks.
19971 They weren't needed, since make_gap checks for buffer overflow.
19972 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19973 The old code merely checked for Emacs fixnum overflow, and relied
19974 on undefined (wraparound) behavior. The new code avoids undefined
19975 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19977 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19978 Tune. Don't use wider integers than needed. Don't use alloca.
19979 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19981 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19983 * insdel.c, lisp.h (buffer_overflow): New function.
19984 (insert_from_buffer_1, replace_range, replace_range_2):
19985 * insdel.c (make_gap_larger):
19986 * editfns.c (Finsert_char):
19987 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19989 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19991 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19993 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19995 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19996 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19998 * fileio.c: Don't assume EMACS_INT fits in off_t.
19999 (emacs_lseek): New static function.
20000 (Finsert_file_contents, Fwrite_region): Use it.
20001 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
20003 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
20005 * fns.c: Don't overflow int when computing a list length.
20006 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
20007 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
20008 truncation on 64-bit hosts. Check for QUIT every
20009 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
20010 faster and is responsive enough.
20011 (Flength): Report an error instead of overflowing an integer.
20012 (Fsafe_length): Return a float if the value is not representable
20013 as a fixnum. This shouldn't happen except in contrived situations.
20014 (Fnthcdr, Fsort): Don't assume list length fits in int.
20015 (Fcopy_sequence): Don't assume vector length fits in int.
20017 * alloc.c: Check that resized vectors' lengths fit in fixnums.
20018 (header_size, word_size): New constants.
20019 (allocate_vectorlike): Don't check size overflow here.
20020 (allocate_vector): Check it here instead, since this is the only
20021 caller of allocate_vectorlike that could cause overflow.
20022 Check that the new vector's length is representable as a fixnum.
20024 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
20025 The previous code was bogus. For example, next_almost_prime (32)
20026 returned 39, which is undesirable as it is a multiple of 3; and
20027 next_almost_prime (24) returned 25, which is a multiple of 5 so
20028 why was the code bothering to check for multiples of 7?
20030 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
20032 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
20034 Variadic C functions now count arguments with ptrdiff_t.
20035 This partly undoes my 2011-03-30 change, which replaced int with size_t.
20036 Back then I didn't know that the Emacs coding style prefers signed int.
20037 Also, in the meantime I found a few more instances where arguments
20038 were being counted with int, which may truncate counts on 64-bit
20039 machines, or EMACS_INT, which may be unnecessarily wide.
20040 * lisp.h (struct Lisp_Subr.function.aMANY)
20041 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
20042 Arg counts are now ptrdiff_t, not size_t.
20043 All variadic functions and their callers changed accordingly.
20044 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
20045 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
20046 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
20047 * callint.c (Fcall_interactively): Check arg count for overflow,
20048 to avoid potential buffer overrun. Use signed char, not 'int',
20049 for 'varies' array, so that we needn't bother to check its size
20050 calculation for overflow.
20051 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
20052 * eval.c (apply_lambda):
20053 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
20054 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
20055 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
20057 * callint.c (Fcall_interactively): Don't use index var as event count.
20059 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
20060 * mem-limits.h (SIZE): Remove; no longer used.
20062 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
20064 Remove unnecessary casts.
20065 * xterm.c (x_term_init):
20066 * xfns.c (x_set_border_pixel):
20067 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
20068 These aren't needed now that we assume ANSI C.
20070 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
20071 It's more likely to cause problems (due to unsigned overflow)
20074 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
20076 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
20078 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
20080 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
20082 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
20084 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
20086 GLYPH_CODE_FACE returns EMACS_INT, not int.
20087 * dispextern.h (merge_faces):
20088 * xfaces.c (merge_faces):
20089 * xdisp.c (get_next_display_element, next_element_from_display_vector):
20090 Don't assume EMACS_INT fits in int.
20092 * character.h (CHAR_VALID_P): Remove unused parameter.
20093 * fontset.c, lisp.h, xdisp.c: All uses changed.
20095 * editfns.c (Ftranslate_region_internal): Omit redundant test.
20097 * fns.c (concat): Minor tuning based on overflow analysis.
20098 This doesn't fix any bugs. Use int to hold character, instead
20099 of constantly refetching from Emacs object. Use XFASTINT, not
20100 XINT, for value known to be a character. Don't bother comparing
20101 a single byte to 0400, as it's always less.
20103 * floatfns.c (Fexpt):
20104 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
20106 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
20109 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
20111 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
20112 Without this fix, on a 64-bit host (aset S 0 4294967386) would
20113 incorrectly succeed when S was a string, because 4294967386 was
20114 truncated before it was used.
20116 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
20117 Otherwise, an out-of-range integer could cause undefined behavior
20120 * composite.c: Use int, not EMACS_INT, for characters.
20121 (fill_gstring_body, composition_compute_stop_pos): Use int, not
20122 EMACS_INT, for values that are known to be in character range.
20123 This doesn't fix any bugs but is the usual style inside Emacs and
20124 may generate better code on 32-bit machines.
20126 Make sure a 64-bit char is never passed to ENCODE_CHAR.
20127 This is for reasons similar to the recent CHAR_STRING fix.
20128 * charset.c (Fencode_char): Check that character arg is actually
20129 a character. Pass an int to ENCODE_CHAR.
20130 * charset.h (ENCODE_CHAR): Verify that the character argument is no
20131 wider than 'int', as a compile-time check to prevent future regressions
20134 * character.c (char_string): Remove unnecessary casts.
20136 Make sure a 64-bit char is never passed to CHAR_STRING.
20137 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
20138 by silently ignoring the top 32 bits, allowing some values
20139 that were far too large to be valid characters.
20140 * character.h: Include <verify.h>.
20141 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
20142 arguments are no wider than unsigned, as a compile-time check
20143 to prevent future regressions in this area.
20145 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
20146 (Fsubst_char_in_region):
20148 * xdisp.c (decode_mode_spec_coding):
20149 Adjust to CHAR_STRING's new requirement.
20150 * editfns.c (Finsert_char, Fsubst_char_in_region):
20151 * fns.c (concat): Check that character args are actually
20152 characters. Without this test, these functions did the wrong
20153 thing with wildly out-of-range values on 64-bit hosts.
20155 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
20156 These casts should not be needed on 32-bit hosts, either.
20157 * keyboard.c (read_char):
20158 * lread.c (Fload): Remove casts to unsigned.
20160 * lisp.h (UNSIGNED_CMP): New macro.
20161 This fixes comparison bugs on 64-bit hosts.
20162 (ASCII_CHAR_P): Use it.
20163 * casefiddle.c (casify_object):
20164 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
20165 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
20166 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
20167 * dispextern.h (FACE_FROM_ID):
20168 * keyboard.c (read_char): Use UNSIGNED_CMP.
20170 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
20171 not to EMACS_INT, to avoid GCC warning.
20173 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
20175 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
20176 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
20177 isn't needed on 32-bit machines.
20179 * buffer.c (Fgenerate_new_buffer_name):
20180 Use EMACS_INT for count, not int.
20181 (advance_to_char_boundary): Return EMACS_INT, not int.
20183 * data.c (Qcompiled_function): Now static.
20185 * window.c (window_body_lines): Now static.
20187 * image.c (gif_load): Rename local to avoid shadowing.
20189 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
20190 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
20191 * alloc.c (make_save_value): Integer argument is now of type
20192 ptrdiff_t, not int.
20193 (mark_object): Use ptrdiff_t, not int.
20194 * lisp.h (pD): New macro.
20195 * print.c (print_object): Use it.
20197 * alloc.c: Use EMACS_INT, not int, to count objects.
20198 (total_conses, total_markers, total_symbols, total_vector_size)
20199 (total_free_conses, total_free_markers, total_free_symbols)
20200 (total_free_floats, total_floats, total_free_intervals)
20201 (total_intervals, total_strings, total_free_strings):
20202 Now EMACS_INT, not int. All uses changed.
20203 (Fgarbage_collect): Compute overall total using a double, so that
20204 integer overflow is less likely to be a problem. Check for overflow
20205 when converting back to an integer.
20206 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
20207 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
20208 These were 'int' variables that could overflow on 64-bit hosts;
20209 they were never used, so remove them instead of repairing them.
20210 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
20211 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
20212 Previously, this ceilinged at INT_MAX, but that doesn't work on
20214 (allocate_pseudovector): Don't use EMACS_INT when int would do.
20216 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
20217 (allocate_vectorlike): Check for ptrdiff_t overflow.
20218 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
20219 when a (possibly-narrower) signed value would do just as well.
20220 We prefer using signed arithmetic, to avoid comparison confusion.
20222 * alloc.c: Catch some string size overflows that we were missing.
20223 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20224 for convenience in STRING_BYTES_MAX.
20225 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
20226 The definition here is exact; the one in lisp.h was approximate.
20227 (allocate_string_data): Check for string overflow. This catches
20228 some instances we weren't catching before. Also, it catches
20229 size_t overflow on (unusual) hosts where SIZE_MAX <= min
20230 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
20231 and ptrdiff_t and EMACS_INT are both 64 bits.
20233 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20234 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
20235 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
20237 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
20239 * alloc.c (Fmake_string): Check for out-of-range init.
20241 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
20243 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
20245 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
20247 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
20248 xg_get_default_scrollbar_width.
20250 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
20251 (int_gtk_range_get_value): Move to the scroll bar part of the file.
20252 (style_changed_cb): Call update_theme_scrollbar_width and call
20253 x_set_scroll_bar_default_width and xg_frame_set_char_size for
20254 all frames (Bug#8505).
20255 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
20256 Call gtk_window_set_resizable if HAVE_GTK3.
20257 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
20258 and height if HAVE_GTK3 (Bug#8505).
20259 (scroll_bar_width_for_theme): New variable.
20260 (update_theme_scrollbar_width): New function.
20261 (xg_get_default_scrollbar_width): Move code to
20262 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
20263 (xg_initialize): Call update_theme_scrollbar_width.
20265 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
20267 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
20269 2011-06-12 Martin Rudalics <rudalics@gmx.at>
20271 * frame.c (make_frame): Call other_buffer_safely instead of
20274 * window.c (temp_output_buffer_show): Call display_buffer with
20275 second argument Vtemp_buffer_show_specifiers and reset latter
20276 immediately after the call.
20277 (Vtemp_buffer_show_specifiers): New variable.
20278 (auto_window_vscroll_p, next_screen_context_lines)
20279 (Vscroll_preserve_screen_position): Remove leading asterisks from
20282 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
20284 Fix minor problems found by GCC 4.6.0 static checking.
20285 * buffer.c (Qclone_number): Remove for now, as it's unused.
20286 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
20287 (record_buffer): Remove unused local.
20288 * frame.c (other_visible_frames, frame_buffer_list): Now static.
20289 (set_frame_buffer_list): Remove; unused.
20290 * frame.h (other_visible_frames): Remove decl.
20291 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
20292 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
20293 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
20295 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
20296 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
20297 Define only if HAVE_GPM.
20298 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
20299 (update_hints_inhibit): Remove; never set. All uses removed.
20300 * widgetprv.h (emacsFrameClassRec): Remove decl.
20301 * window.c (delete_deletable_window): Now returns void, since it
20302 wasn't returning anything.
20303 (compare_window_configurations): Remove unused locals.
20304 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
20305 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
20306 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
20307 the same widths as pointers. This follows up on the 2011-05-06 patch.
20308 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
20309 * xterm.h: Likewise.

20315 (LISP_H): Add lib/intprops.h.
20317 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
20319 * image.c (gif_load): Add animation frame delay to the metadata.
20320 (syms_of_image): Use DEFSYM. New symbol `delay'.
20322 2011-06-11 Martin Rudalics <rudalics@gmx.at>
20324 * window.c (delete_deletable_window): Re-add.
20325 (Fset_window_configuration): Rewrite to handle dead buffers and
20326 consequently deletable windows.
20327 (window_tree, Fwindow_tree): Remove. Supply functionality in
20329 (compare_window_configurations): Simplify code.
20331 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
20333 * image.c (imagemagick_load_image): Fix type mismatch.
20334 (Fimagemagick_types): Likewise.
20336 * window.h (replace_buffer_in_windows): Declare.
20338 2011-06-11 Martin Rudalics <rudalics@gmx.at>
20340 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
20341 Qclone_number. Remove external declaration of Qdelete_window.
20342 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
20344 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
20345 Run Qbuffer_list_update_hook if allowed.
20346 (Fother_buffer): Rewrite doc-string. Major rewrite for new
20347 buffer list implementation.
20348 (other_buffer_safely): New function.
20349 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
20350 calls to replace_buffer_in_windows and
20351 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
20353 (record_buffer): Inhibit quitting and rewrite using quittable
20354 functions. Run Qbuffer_list_update_hook if allowed.
20355 (Frecord_buffer, Funrecord_buffer): New functions.
20356 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
20357 Move switch-to-buffer to window.el.
20358 (bury-buffer): Move to window.el.
20359 (Vbuffer_list_update_hook): New variable.
20361 * lisp.h (other_buffer_safely): Add prototype in buffer.c
20364 * window.h (resize_frame_windows): Move up in code.
20365 (Fwindow_frame): Remove EXFUN.
20366 (replace_buffer_in_all_windows): Remove prototype.
20367 (replace_buffer_in_windows_safely): Add prototype.
20369 * window.c: Declare Qdelete_window static again. Move down
20370 declaration of select_count.
20371 (Fnext_window, Fprevious_window): Rewrite doc-strings.
20372 (Fother_window): Move to window.el.
20373 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
20374 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
20375 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
20377 (replace_buffer_in_windows): Implement by calling
20378 Qreplace_buffer_in_windows.
20379 (replace_buffer_in_all_windows): Remove with some functionality
20380 moved into replace_buffer_in_windows_safely.
20381 (replace_buffer_in_windows_safely): New function.
20382 (select_window_norecord, select_frame_norecord): Move in front
20383 of run_window_configuration_change_hook. Remove now obsolete
20385 (Fset_window_buffer): Rewrite doc-string.
20386 Call Qrecord_window_buffer.
20387 (keys_of_window): Move binding for other-window to window.el.
20389 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
20391 * dispextern.h (struct image): Replace data member, whose int_val
20392 and ptr_val fields were not used by anything, with a single
20395 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
20396 (gif_clear_image, gif_load, imagemagick_load_image)
20397 (gs_clear_image, gs_load): Callers changed.

20872 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20873 All callers changed. (Bug#8762)
20875 * gnutls.c: Use Emacs's memory allocators.
20876 Without this change, the gnutls library would invoke malloc etc.
20877 directly, which causes problems on non-SYNC_INPUT hosts, and which
20878 runs afoul of improving memory_full behavior. (Bug#8761)
20879 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20880 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20881 xfree instead of the default malloc, realloc, free.
20882 (Fgnutls_boot): No need to check for memory allocation failure,
20883 since xmalloc does that for us.
20885 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20886 * category.c (hash_get_category_set):
20887 * ccl.c (ccl_driver):
20888 * charset.c (Fdefine_charset_internal):
20889 * charset.h (struct charset.hash_index):

20891 (composition_gstring_put_cache):
20892 * composite.h (struct composition.hash_index):
20893 * dispextern.h (struct image.hash):
20894 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
20895 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

20899 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20900 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20901 * image.c (make_image, search_image_cache, lookup_image)
20902 (xpm_put_color_table_h):
20903 * lisp.h (struct Lisp_Hash_Table):
20904 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20905 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20906 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20907 * alloc.c (allocate_vectorlike):
20908 Check for overflow in vector size calculations.
20909 * ccl.c (ccl_driver):
20910 Check for overflow when converting EMACS_INT to int.
20911 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20912 need to be updated by these changes.
20913 * fns.c (make_hash_table, maybe_resize_hash_table):
20914 Check for integer overflow with large hash tables.
20915 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20916 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20917 (SXHASH_REDUCE): New macro.
20918 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20919 Use it instead of discarding useful hash info with large hash values.
20920 (sxhash_float): New function.
20921 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20922 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20923 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20924 Rewrite to use FIXNUM_BITS, as this simplifies things.
20925 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20926 Adjust signatures to match updated version of code.
20927 (consing_since_gc): Now EMACS_INT, since a single hash table can
20928 use more than INT_MAX bytes.
20930 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20932 Make it possible to build with GCC-4.6+ -O2 -flto.
20934 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20936 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20938 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20939 Call minibuffer-inactive-mode.
20941 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20943 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20944 Update dependencies.
20946 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20948 * data.c (init_data): Remove code for UTS, this system is not
20951 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20953 Don't force ./temacs to start in terminal mode.
20955 * frame.c (make_initial_frame): Initialize faces in all cases, not
20956 only when CANNOT_DUMP is defined.
20957 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20959 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20961 * dispnew.c (add_window_display_history): Use const for the string
20962 pointer. Remove declaration, not needed.
20964 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20966 Use 'inline', not 'INLINE'.
20967 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20968 * alloc.c, fontset.c (INLINE): Remove.
20969 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20970 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20971 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20972 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20973 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20975 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20977 Make it possible to run ./temacs.
20979 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20980 syms_of_callproc does the same thing. Remove test for
20981 "initialized", do it in the caller.
20982 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20984 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20986 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20987 (read_minibuf): Use get_minibuffer.
20988 (syms_of_minibuf): Use DEFSYM.
20989 (Qmetadata): New var.
20990 * data.c (Qbuffer): Don't make it static.
20991 (syms_of_data): Use DEFSYM.
20993 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20995 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20996 (CCL_CODE_MIN): New macro.
20998 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
21000 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
21002 * eval.c (Qdebug): Now static.
21003 * lisp.h (Qdebug): Remove decl. This reverts a part of the
21004 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
21005 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
21007 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
21009 * image.c: Various fixes to ImageMagick code comments.
21010 (Fimagemagick_types): Doc fix.
21012 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
21014 Minor fixes prompted by GCC 4.6.0 warnings.
21016 * xselect.c (converted_selections, conversion_fail_tag): Now static.
21018 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
21019 (x_clipboard_manager_save_all): Move extern decl to ...
21020 * xterm.h: ... here, so that it can be checked for consistency.
21022 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
21024 * xselect.c (x_clipboard_manager_save_frame)
21025 (x_clipboard_manager_save_all): New functions.
21026 (Fx_clipboard_manager_save): Lisp function deleted.
21028 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
21029 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
21031 * xterm.h: Update prototype.
21033 2011-05-28 William Xu <william.xwl@gmail.com>
21035 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
21036 exiting (Bug#8239).
21038 2011-05-28 Jim Meyering <meyering@redhat.com>
21040 Avoid a sign-extension bug in crypto_hash_function.
21041 * fns.c (to_uchar): Define.
21042 (crypto_hash_function): Use it to convert some newly-signed
21043 variables to unsigned, to avoid sign-extension bugs. For example,
21044 without this change, (md5 "truc") would evaluate to
21045 45723a2aff78ff4fff7fff1114760e62 rather than the expected
21046 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
21047 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
21049 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21051 Integer overflow fixes.
21053 * dbusbind.c: Serial number integer overflow fixes.
21054 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
21055 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
21056 to hold a serial number that is too large for a fixnum.
21057 (Fdbus_method_return_internal, Fdbus_method_error_internal):
21058 Check for serial numbers out of range. Decode any serial number
21059 that was so large that it became a float. (Bug#8722)
21061 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
21062 (Fdbus_call_method, Fdbus_call_method_asynchronously):
21063 Use XFASTINT rather than XUINT when numbers are nonnegative.
21064 (xd_append_arg, Fdbus_method_return_internal):
21065 (Fdbus_method_error_internal): Likewise. Also, for unsigned
21066 arguments, check that Lisp number is nonnegative, rather than
21067 silently wrapping negative numbers around. (Bug#8722)
21068 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
21071 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
21073 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
21075 ccl: Add integer overflow checks.
21076 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
21077 (IN_INT_RANGE): New macros.
21078 (ccl_driver): Use them to check for integer overflow when
21079 decoding a CCL program. Many of the new checks are whether XINT (x)
21080 fits in int; it doesn't always, on 64-bit hosts. The new version
21081 doesn't catch all possible integer overflows, but it's an
21082 improvement. (Bug#8719)
21084 * alloc.c (make_event_array): Use XINT, not XUINT.
21085 There's no need for unsigned here.
21087 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
21088 This follows up to the 2011-05-06 change that substituted uintptr_t
21089 for EMACS_INT. This case wasn't caught back then.
21091 Rework Fformat to avoid integer overflow issues.
21092 * editfns.c: Include <float.h> unconditionally, as it's everywhere
21093 now (part of C89). Include <verify.h>.
21094 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
21095 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
21096 (Fformat): Avoid the prepass trying to compute sizes; it was only
21097 approximate and thus did not catch overflow reliably. Instead, walk
21098 through the format just once, formatting and computing sizes as we go,
21099 checking for integer overflow at every step, and allocating a larger
21100 buffer as needed. Keep track separately whether the format is
21101 multibyte. Keep only the most-recently calculated precision, rather
21102 than them all. Record whether each argument has been converted to
21103 string. Use EMACS_INT, not int, for byte and char and arg counts.
21104 Support field widths and precisions larger than INT_MAX. Avoid
21105 sprintf's undefined behavior with conversion specifications such as %#d
21106 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
21107 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
21108 formatting out-of-range floating point numbers with int
21109 formats. (Bug#8668)
21111 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
21113 * data.c: Avoid integer truncation in expressions involving floats.
21114 * data.c: Include <intprops.h>.
21115 (arith_driver): When there's an integer overflow in an expression
21116 involving floating point, convert the integers to floating point
21117 so that the resulting value does not suffer from catastrophic
21118 integer truncation. For example, on a 64-bit host (* 4
21119 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
21120 Do not rely on undefined behavior after integer overflow.
21122 merge count_size_as_multibyte, parse_str_to_multibyte
21123 * character.c, character.h (count_size_as_multibyte):
21124 Rename from parse_str_to_multibyte; all uses changed.
21125 Check for integer overflow.
21126 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
21127 since it's now a duplicate of the other. This is more of
21128 a character than a buffer op, so better that it's in character.c.
21129 * fns.c, print.c: Adjust to above changes.
21131 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
21133 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
21135 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21137 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21138 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
21139 (x_clipboard_manager_save): Now static.
21140 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
21142 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21143 (crypto_hash_function): Now static.
21144 Fix pointer signedness problems. Avoid unnecessary initializations.
21146 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
21148 * termhooks.h (Vselection_alist): Make it terminal-local.
21150 * terminal.c (create_terminal): Initialize it.
21152 * xselect.c: Support for clipboard managers.
21153 (Vselection_alist): Move to termhooks.h as terminal-local var.
21154 (LOCAL_SELECTION): New macro.
21155 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
21156 (symbol_to_x_atom): Remove gratuitous arg.
21157 (x_handle_selection_request, lisp_data_to_selection_data)
21158 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
21159 (x_own_selection, x_get_local_selection, x_convert_selection):
21160 New arg, specifying work frame. Use terminal-local Vselection_alist.
21161 (some_frame_on_display): Delete unused function.
21162 (Fx_own_selection_internal, Fx_get_selection_internal)
21163 (Fx_disown_selection_internal, Fx_selection_owner_p)
21164 (Fx_selection_exists_p): New optional frame arg.
21165 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
21166 (x_handle_selection_clear): Don't treat other terminals with the
21167 same keyboard specially. Use the terminal-local Vselection_alist.
21168 (x_clear_frame_selections): Use Frun_hook_with_args.
21170 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
21172 * xterm.h: Add support for those atoms.
21174 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
21176 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
21177 (converted_selections, conversion_fail_tag): New global variables.
21178 (x_selection_request_lisp_error): Free the above.
21179 (x_get_local_selection): Remove unnecessary code.
21180 (x_reply_selection_request): Args changed; handle arbitrary array
21181 of converted selections stored in converted_selections.
21182 Separate the XChangeProperty and SelectionNotify steps.
21183 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21184 (x_convert_selection): New function.
21185 (x_handle_selection_event): Simplify.
21186 (x_get_foreign_selection): Don't ignore incoming requests while
21187 waiting for an answer; this will fail when we implement
21188 SAVE_TARGETS, and seems unnecessary anyway.
21189 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21190 (Vx_sent_selection_functions): Doc fix.
21192 2011-05-26 Leo Liu <sdl.web@gmail.com>
21194 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21196 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21198 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21200 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21201 for fringe update if it has periodic bitmap.
21202 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21203 and fringe_bitmap_periodic_p.
21205 * fringe.c (get_fringe_bitmap_data): New function.
21206 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21207 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21208 row. Mark glyph row for fringe update if periodicity changed.
21210 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21211 for fringe update unless it has periodic bitmap.
21213 2011-05-25 Kenichi Handa <handa@m17n.org>

21231 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21232 Remove macros that are defined and never used.
21233 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21235 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21237 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21238 (Fx_get_selection_internal): Minor cleanup.

21264 report_file_error introduced by the change from 2011-05-07.
21266 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21268 * systime.h (Time): Define only if emacs is defined.
21269 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21270 where the include path doesn't have X11/X.h by default. See
21271 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21273 2011-05-20 Kenichi Handa <handa@m17n.org>
21275 * composite.c (find_automatic_composition): Fix previous change.
21277 2011-05-20 Glenn Morris <rgm@gnu.org>

21288 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21289 (lisp): Set the order to that of loadup.el.
21290 (shortlisp): Make it a copy of $lisp.
21291 (SOME_MACHINE_LISP): Remove.
21292 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21293 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21295 2011-05-18 Kenichi Handa <handa@m17n.org>
21297 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21298 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21299 (find_automatic_composition): Mostly rewrite for efficiency.
21301 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
21303 * makefile.w32-in: Update dependencies.
21305 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21307 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21308 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21310 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21312 Fix some integer overflow issues, such as string length overflow.
21314 * insdel.c (count_size_as_multibyte): Check for string overflow.
21316 * character.c (lisp_string_width): Check for string overflow.
21317 Use EMACS_INT, not int, for string indexes and lengths; in
21318 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21319 the resulting string length overflows an EMACS_INT; instead,
21320 report a string overflow if no precision given. When checking for
21321 precision exhaustion, use a check that cannot possibly have
21322 integer overflow. (Bug#8675)
21323 * character.h (lisp_string_width): Adjust to new signature.
21325 * alloc.c (string_overflow): New function.
21326 (Fmake_string): Use it. This doesn't change behavior, but saves
21327 a few bytes and will simplify future changes.
21328 * character.c (string_escape_byte8): Likewise.
21329 * lisp.h (string_overflow): New decl.
21331 Fixups, following up to the user-interface timestamp change.
21332 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21333 for UI timestamps, instead of unsigned long.
21334 * msdos.c (mouse_get_pos): Likewise.
21335 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21336 * w32gui.h (Time): Define by including "systime.h" rather than by
21337 declaring it ourselves. (Bug#8664)
21339 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21340 * image.c (clear_image_cache): Likewise.
21342 * term.c (term_mouse_position): Don't assume time_t wraparound.
21344 Be more systematic about user-interface timestamps.
21345 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21346 and sometimes 'EMACS_UINT', to represent these timestamps.
21347 This change causes it to use 'Time' uniformly, as that's what X uses.
21348 This makes the code easier to follow, and makes it easier to catch
21349 integer overflow bugs such as Bug#8664.
21350 * frame.c (Fmouse_position, Fmouse_pixel_position):
21351 Use Time, not unsigned long, for user-interface timestamps.
21352 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21353 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21354 * keyboard.h (last_event_timestamp): Likewise.
21355 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21356 * menu.h (xmenu_show): Likewise.
21357 * term.c (term_mouse_position): Likewise.
21358 * termhooks.h (struct input_event.timestamp): Likewise.
21359 (struct terminal.mouse_position_hook): Likewise.
21360 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21361 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21362 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21363 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21364 what it was before.
21365 * menu.h, termhooks.h: Include "systime.h", for Time.
21367 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21368 Don't assume that the difference between two unsigned long values
21369 can fit into an integer. At this point, we know button_down_time
21370 <= event->timestamp, so the difference must be nonnegative, so
21371 there's no need to cast the result if double-click-time is
21372 nonnegative, as it should be; check that it's nonnegative, just in
21373 case. This bug is triggered when events are more than 2**31 ms
21374 apart (about 25 days). (Bug#8664)
21376 * xselect.c (last_event_timestamp): Remove duplicate decl.
21377 (x_own_selection): Remove needless cast to unsigned long.
21379 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21380 that always fit in int. Use a sentinel instead of a counter, to
21381 avoid a temp and to allay GCC's concerns about possible int overflow.
21382 * frame.h (struct frame): Use int for menu_bar_items_used
21383 instead of EMACS_INT, since it always fits in int.
21385 * menu.c (grow_menu_items): Check for int overflow.
21387 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21389 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21390 Before, the code was not consistent. These values cannot exceed
21391 2**31 - 1 so there's no need to make them unsigned.
21392 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21393 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21394 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21396 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21398 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21399 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21400 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21401 presumably because the widths might not match.
21403 * window.c (size_window): Avoid needless test at loop start.
21405 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21407 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21409 2011-05-12 Drew Adams <drew.adams@oracle.com>
21411 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21413 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21415 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21416 `width' to `bar_area_x' and `bar_area_width', respectively.
21417 (x_scroll_run): Take account of fringe background extension.
21419 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21420 Rename local vars `left' and `width' to `bar_area_x' and
21421 `bar_area_width', respectively.
21422 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21423 background extension.
21425 2011-05-10 Jim Meyering <meyering@redhat.com>
21427 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21429 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21431 * image.c (Finit_image_library): Return t for built-in image types,
21432 like pbm and xbm. (Bug#8640)
21434 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21436 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21438 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21440 * w32console.c (Fset_screen_color): Doc fix.
21441 (Fget_screen_color): New function.
21442 (syms_of_ntterm): Defsubr it.
21444 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21445 unlink the temporary file if Fcall_process didn't create it in the
21447 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21448 child process will be redirected to a file specified with `:file'.
21449 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21450 cue to call_process_cleanup not to close that handle.
21452 2011-05-07 Ben Key <bkey76@gmail.com>
21454 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21455 one of two shell specific rules, either bootstrap-temacs-CMD or
21456 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21457 to the previous implementation of the bootstrap-temacs rule.
21458 The bootstrap-temacs-CMD rule is similar to the previous
21459 implementation of the bootstrap-temacs rule except that it
21460 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21463 These changes, along with some changes to nt/configure.bat,
21464 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21465 earlier fix to add support for --cflags and --ldflags options
21466 that include quotes so that it works whether make uses cmd or
21469 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21471 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21472 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21474 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21475 a string. Handle both cases.
21476 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21477 (Fdbus_register_method): Use Qinvalid_function.
21479 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21481 * makefile.w32-in: Update dependencies.
21482 (LISP_H): Add inttypes.h and stdin.h.
21483 (PROCESS_H): Add unistd.h.
21485 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21487 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21488 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21490 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21492 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21494 * term.c (vfatal): Remove stray call to va_end.
21495 It's not needed and the C Standard doesn't allow it here anyway.
21497 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21498 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21500 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21503 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21505 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21507 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21509 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21511 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21513 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21514 * charset.c (Fdefine_charset_internal): Don't initialize
21515 charset.code_space[15]. The value was garbage, on hosts with
21516 32-bit int (Bug#8600).
21518 * lread.c (read_integer): Be more consistent with string-to-number.
21519 Use string_to_number to do the actual conversion; this avoids
21520 rounding errors and fixes some other screwups. Without this fix,
21521 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21522 (digit_to_number): Move earlier, for benefit of read_integer.
21523 Return -1 if the digit is out of range for the base, -2 if it is
21524 not a digit in any supported base. (Bug#8602)
21526 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21528 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21529 to match comment at start of function. This also removes a
21530 GCC warning about overflow in a 32+64-bit port.
21532 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21534 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21535 Reported by Stefan Monnier in
21536 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21537 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21538 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21540 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21541 (EMACS_UINTPTR): Likewise, with uintptr_t.
21543 * lisp.h: Prefer 64-bit EMACS_INT if available.
21544 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21545 on 32-bit hosts that have 64-bit int, so that they can access
21547 However, temporarily disable this change unless the temporary
21548 symbol WIDE_EMACS_INT is defined.
21550 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21552 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21553 This removes an assumption that EMACS_INT and long are the same
21554 width as pointers. The assumption is true for Emacs porting targets
21555 now, but we want to make other targets possible.
21556 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21557 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21558 In the rest of the code, change types of integers that hold casted
21559 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21560 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21561 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21562 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21563 No need to cast type when ORing.
21564 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21565 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21566 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21567 assume EMACS_INT is the same width as char *.
21568 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21569 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21570 Remove no-longer-needed casts.
21571 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21572 (xg_tool_bar_help_callback, xg_make_tool_item):
21573 Use EMACS_INTPTR to hold an integer
21574 that will be cast to void *; this can avoid a GCC warning
21575 if EMACS_INT is not the same width as void *.
21576 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21577 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21578 (current_message_1, set_message_1):
21579 Use a local to convert to proper width without a cast.
21580 * xmenu.c (dialog_selection_callback): Likewise.
21582 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21583 Also, don't assume VALBITS / RAND_BITS is less than 5,
21584 and don't rely on undefined behavior when shifting a 1 left into
21586 * lisp.h (get_random): Change signature to match.
21588 * lread.c (hash_string): Use size_t, not int, for hash computation.
21589 Normally we prefer signed values; but hashing is special, because
21590 it's better to use unsigned division on hash table sizes so that
21591 the remainder is nonnegative. Also, size_t is the natural width
21592 for hashing into memory. The previous code used 'int', which doesn't
21593 retain enough info to hash well into very large tables.
21594 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21596 * dbusbind.c: Don't possibly lose pointer info when converting.
21597 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21598 Use XPNTR rather than XHASH, so that the high-order bits of
21599 the pointer aren't lost when converting through void *.
21601 * eval.c (Fautoload): Don't double-shift a pointer.
21603 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21605 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21607 * gnutls.c (DEF_GNUTLS_FN):
21608 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21610 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21612 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21615 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21617 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21618 New version that can reserve upto 2GB of heap space.
21620 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21622 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21624 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21626 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21627 `gnutls_certificate_set_x509_key_file'.
21629 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21631 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21632 Update dependencies.
21634 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21636 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21637 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21638 Remove unused parameter `fildes'.
21639 * process.c (read_process_output, send_process): Don't pass it.
21641 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21643 Fix previous change: the library cache is defined in w32.c.
21644 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21645 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21647 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21649 Implement dynamic loading of GnuTLS on Windows.
21651 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21652 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21653 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21656 * gnutls.c (Qgnutls_dll): Define.
21657 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21658 (gnutls_*): Declare function pointers.
21659 (init_gnutls_functions): New function to initialize function pointers.
21660 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21661 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21662 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21663 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21664 (emacs_gnutls_write, emacs_gnutls_read)
21665 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21666 (Fgnutls_available_p): New function.
21667 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21668 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21669 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21671 * image.c: Include w32.h.
21672 (Vimage_type_cache): Delete.
21673 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
21674 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21675 (w32_delayed_load): Move to w32.c.
21677 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21679 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21680 (w32_delayed_load): Move from image.c. When loading a library, record
21681 its filename in the :loaded-from property of the library id.
21682 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21683 Initialize and staticpro them.
21684 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21686 * process.c: Include lisp.h before w32.h, not after.
21687 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21688 instead of gnutls_record_check_pending.
21690 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21692 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21694 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21695 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21698 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21700 * xterm.c (x_set_frame_alpha): Do not set property on anything
21701 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21703 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21705 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21707 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21709 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21710 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
21711 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

21716 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
21717 (Qgnutls_bootprop_callbacks_verify): Make static.

21729 * sysdep.c (interruptible_wait_for_termination): New function
21730 which is like wait_for_termination, but allows keyboard
21733 * callproc.c (Fcall_process): Add (:file "file") as an option for
21735 (Fcall_process_region): Ditto.
21737 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21739 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21740 rather than `XVECTOR (FOO)->size'.
21742 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21743 inttypes.h, as a gnulib replacement is used if it not available in
21746 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21748 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21749 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21750 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21752 * coding.c (coding_alloc_by_realloc): Error out if destination
21753 will grow beyond MOST_POSITIVE_FIXNUM.
21754 (decode_coding_emacs_mule): Abort if there isn't enough place in
21755 charbuf for the composition carryover bytes. Reserve an extra
21756 space for up to 2 characters produced in a loop.
21757 (decode_coding_iso_2022): Abort if there isn't enough place in
21758 charbuf for the composition carryover bytes.
21760 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21762 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21763 aborting when %lld or %lll format is passed.
21764 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21765 %llo or %llx format is passed. (Bug#8545)
21767 * window.c (window_scroll_line_based): Use a marker instead of
21768 simple variables to record original value of point. (Bug#7952)
21770 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21771 produced by %s or %c overflows available buffer space. (Bug#8545)
21773 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21775 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21776 (SIZE_MAX): Move defn after all includes, as they might #define it.
21778 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21780 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21782 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21784 * keyboard.c (Qdelayed_warnings_hook): Define.
21785 (command_loop_1): Run `delayed-warnings-hook'
21786 if Vdelayed_warnings_list is non-nil.
21787 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21788 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21790 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21792 * doprnt.c (doprnt): Don't return value smaller than the buffer
21793 size if the message was truncated. (Bug#8545).
21795 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21797 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21798 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21800 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21802 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21804 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21806 * makefile.w32-in: Update dependencies.
21808 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21810 Improve `doprnt' and its usage. (Bug#8545)
21811 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21812 `format_end'. Remove support for %l as a conversion specifier.
21813 Don't use xrealloc. Improve diagnostics when the %l size modifier
21814 is used. Update the commentary.
21816 * eval.c (verror): Simplify calculation of size_t.
21818 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21821 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21823 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21826 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21828 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21829 This makes this file independent of the recent pseudovector change.
21831 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21833 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21835 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21836 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21837 Remove unused local.
21838 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21840 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21841 GCC 4.6.0 optimizes based on type-based alias analysis.
21842 For example, if b is of type struct buffer * and v of type struct
21843 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21844 != &v->size, and therefore "v->size = 1; b->size = 2; return
21845 v->size;" must therefore return 1. This assumption is incorrect
21846 for Emacs, since it type-puns struct Lisp_Vector * with many other
21847 types. To fix this problem, this patch adds a new type struct
21848 vectorlike_header that documents the constraints on layout of vectors
21849 and pseudovectors, and helps optimizing compilers not get fooled
21850 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21851 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21852 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21854 (XSETPVECTYPE): Rewrite in terms of new macro.
21855 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21856 This is a bit clearer, and further avoids the possibility of
21857 undesirable aliasing.
21858 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21859 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21860 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21861 since Lisp_Subr is a special case (no "next" field).
21862 (ASIZE): Now uses header.size rather than size.
21863 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21864 to avoid the hassle of writing XVECTOR (foo)->header.size.
21865 (struct vectorlike_header): New type.
21866 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21867 object, to help avoid aliasing.
21868 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21869 (SUBRP): Likewise, since Lisp_Subr is a special case.
21870 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21871 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21872 (struct Lisp_Hash_Table): Combine first two members into a single
21873 struct vectorlike_header member. All uses of "size" and "next" members
21874 changed to be "header.size" and "header.next".
21875 * buffer.h (struct buffer): Likewise.
21876 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21877 * frame.h (struct frame): Likewise.
21878 * process.h (struct Lisp_Process): Likewise.
21879 * termhooks.h (struct terminal): Likewise.
21880 * window.c (struct save_window_data, struct saved_window): Likewise.
21881 * window.h (struct window): Likewise.
21882 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21883 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21884 * buffer.c (init_buffer_once): Likewise.
21885 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21887 * process.c (Fformat_network_address): Use local var for size,
21890 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21892 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21893 * data.c (atof): Remove decl; no longer used or needed.
21894 (digit_to_number): Move to lread.c.
21895 (Fstring_to_number): Use new string_to_number function, to be
21896 consistent with how the Lisp reader treats infinities and NaNs.
21897 Do not assume that floating-point numbers represent EMACS_INT
21898 without losing information; this is not true on most 64-bit hosts.
21899 Avoid double-rounding errors, by insisting on integers when
21900 parsing non-base-10 numbers, as the documentation specifies.
21901 * lisp.h (string_to_number): New decl, replacing ...
21902 (isfloat_string): Remove.
21903 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21904 (read1): Do not accept +. and -. as integers; this
21905 appears to have been a coding error. Similarly, do not accept
21906 strings like +-1e0 as floating point numbers. Do not report
21907 overflow for integer overflows unless the base is not 10 which
21908 means we have no simple and reliable way to continue.
21909 Break out the floating-point parsing into a new
21910 function string_to_number, so that Fstring_to_number parses
21911 floating point numbers consistently with the Lisp reader.
21912 (digit_to_number): Move here from data.c. Make it static inline.
21913 (E_CHAR, EXP_INT): Remove, replacing with ...
21914 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21915 (string_to_number): New function, replacing isfloat_string.
21916 This function checks for valid syntax and produces the resulting
21917 Lisp float number too. Rework it so that string-to-number
21918 no longer mishandles examples like "1.0e+". Use strtoumax,
21919 so that overflow for non-base-10 numbers is reported only when
21920 there's no portable and simple way to convert to floating point.
21922 * textprop.c (set_text_properties_1): Rewrite for clarity,
21923 and to avoid GCC warning about integer overflow.
21925 * intervals.h (struct interval): Use EMACS_INT for members
21926 where EMACS_UINT might cause problems. See
21927 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21928 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21929 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21931 (offset_intervals): Tell GCC not to worry about length overflow
21932 when negating a negative length.
21934 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21935 (overrun_check_free): Likewise.
21937 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21938 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21941 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21942 (gnutls_make_error): Rename local to avoid shadowing.
21943 (gnutls_emacs_global_deinit): ifdef out; not used.
21944 (Fgnutls_boot): Use const for pointer to readonly storage.
21945 Comment out unused local. Fix pointer signedness problems.
21947 * lread.c (openp): Don't stuff size_t into an 'int'.
21948 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21949 about possible signed overflow.
21951 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21952 (GDK_KEY_g): Don't define if already defined.
21953 (xg_prepare_tooltip): Avoid pointer signedness problem.
21954 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21956 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21957 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21959 * xfns.c (Fx_window_property): Simplify a bit,
21960 to make a bit faster and to avoid GCC 4.6.0 warning.
21961 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21963 * fns.c (internal_equal): Don't assume size_t fits in int.
21965 * alloc.c (compact_small_strings): Tighten assertion a little.
21967 Replace pEd with more-general pI, and fix some printf arg casts.
21968 * lisp.h (pI): New macro, generalizing old pEd macro to other
21969 conversion specifiers. For example, use "...%"pI"d..." rather
21970 than "...%"pEd"...".
21971 (pEd): Remove. All uses replaced with similar uses of pI.
21972 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21973 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21974 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21975 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21976 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21977 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21978 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21980 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21981 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21982 * print.c (safe_debug_print, print_object): Likewise.
21983 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21985 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21986 avoiding the 0 flag, which is not portable.
21987 * process.c (Fmake_network_process): Use pI to avoid cast.
21988 * region-cache.c (pp_cache): Likewise.
21989 * xdisp.c (decode_mode_spec): Likewise.
21990 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21991 behavior on 64-bit hosts with printf arg.
21992 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21993 (x_stop_queuing_selection_requests): Likewise.
21994 (x_get_window_property): Don't truncate byte count to an 'int'
21997 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21998 here, since it parses constructs like leading '-' and spaces,
21999 which are not wanted; and it overflows with large numbers.
22000 Instead, simply match F[0-9]+, which is what is wanted anyway.
22002 * alloc.c: Remove unportable assumptions about struct layout.
22003 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
22004 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
22005 (allocate_vectorlike, make_pure_vector): Use the new macros,
22006 plus offsetof, to remove unportable assumptions about struct layout.
22007 These assumptions hold on all porting targets that I know of, but
22008 they are not guaranteed, they're easy to remove, and removing them
22009 makes further changes easier.
22011 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
22012 This doesn't fix a bug but makes the code clearer.
22013 (string_overrun_cookie): Now const. Use initializers that
22014 don't formally overflow signed char, to avoid warnings.
22015 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
22016 can cause Emacs to crash when string overrun checking is enabled.
22017 (allocate_buffer): Don't assume sizeof (struct buffer) is a
22018 multiple of sizeof (EMACS_INT); it need not be, if
22019 alignof(EMACS_INT) < sizeof (EMACS_INT).
22020 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
22022 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
22024 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
22026 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
22028 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
22029 supposed to be handshaking. (Bug#8556)
22030 Reported by Paul Eggert <eggert@cs.ucla.edu>.
22032 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
22034 * lisp.h (Qdebug): List symbol.
22035 * eval.c (Qdebug): Restore global linkage.
22036 * keyboard.c (debug-on-event): New variable.
22037 (handle_user_signal): Break into debugger when debug-on-event
22038 matches the current signal symbol.
22040 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
22042 * alloc.c (check_sblock, check_string_bytes)
22043 (check_string_free_list): Convert to standard C.
22045 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
22047 * w32.c (emacs_gnutls_push): Fix typo.
22049 2011-04-25 Eli Zaretskii <eliz@gnu.org>
22051 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
22052 "cast to pointer from integer of different size".
22054 Improve doprnt and its use in verror. (Bug#8545)
22055 * doprnt.c (doprnt): Document the set of format control sequences
22056 supported by the function. Use SAFE_ALLOCA instead of always
22059 * eval.c (verror): Don't limit the buffer size at size_max-1, that
22060 is one byte too soon. Don't use xrealloc; instead xfree and
22063 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
22065 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
22068 * gnutls.c: Renamed global_initialized to
22069 gnutls_global_initialized. Added internals for the
22070 :verify-hostname-error, :verify-error, and :verify-flags
22071 parameters of `gnutls-boot' and documented those parameters in the
22072 docstring. Start callback support.
22073 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
22074 unless a fatal error occurred. Call gnutls_alert_send_appropriate
22075 on error. Return error code.
22076 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
22077 (emacs_gnutls_read): Likewise.
22078 (Fgnutls_boot): Return handshake error code.
22079 (emacs_gnutls_handle_error): New function.
22080 (wsaerror_to_errno): Likewise.

22083 (emacs_gnutls_push): Likewise.
22085 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
22086 (emacs_gnutls_push): Likewise.
22088 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
22090 * process.c (wait_reading_process_output): Check if GnuTLS
22091 buffered some data internally if no FDs are set for TLS
22094 * makefile.w32-in (OBJ2): Add gnutls.$(O).

22101 display_replaced_before_p argument into display_replaced_p, to
22102 make it consistent with the commentary. Fix typos in the
22105 * textprop.c (syms_of_textprop): Remove dead code.

22111 to changes in oldXMenu/XMenu.h from 2011-04-16.
22112 <menu_help_message, prev_menu_help_message>: Constify.
22113 (IT_menu_make_room): menu->help_text is now `const char **';

22117 to changes in oldXMenu/XMenu.h from 2011-04-16.
22118 (struct XMenu): Declare `help_text' `const char **'.

22129 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
22131 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
22134 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
22135 changes in globals.h immediately force recompilation.
22136 (TAGS): Depend on $(CURDIR)/m/intel386.h and
22137 $(CURDIR)/s/ms-w32.h.
22138 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

22141 (syms_of_character): Don't defsubr it.
22142 <char-direction-table>: Deleted.
22144 2011-04-23 Eli Zaretskii <eliz@gnu.org>
22146 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
22147 * doprnt.c: Include limits.h.
22148 (SIZE_MAX): New macro.
22149 (doprnt): Return a size_t value. 2nd arg is now size_t.
22150 Many local variables are now size_t instead of int or unsigned.
22151 Improve overflow protection. Support `l' modifier for integer
22152 conversions. Support %l conversion. Don't assume an EMACS_INT
22153 argument for integer conversions and for %c.
22155 * lisp.h (doprnt): Restore prototype.
22157 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
22158 $(SRC)/character.h.
22160 * Makefile.in (base_obj): Add back doprnt.o.

22403 * process.c (send_process): Adjust to the new signatures of
22404 emacs_write and emacs_gnutls_write. Do not attempt to store

22628 * editfns.c, lisp.h (get_operating_system_release): Remove.
22629 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
22630 worth the hassle of breaking this out.
22632 * xterm.c: Make symbols static if they're not exported.
22633 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
22634 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

22734 * lisp.h: Remove these decls.
22736 * buffer.c (buffer_count): Remove unused var.
22738 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
22739 so that it's not optimized away.
22740 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
22741 * dispextern.h (bidi_dump_cached_states): Remove, since it's
22742 exported only to the debugger.

22745 * atimer.h (run_all_atimers): Remove; not exported.
22747 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
22748 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
22749 was inaccessible from Lisp.
22750 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
22751 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
22753 alloc.c: Import and export fewer symbols, and remove unused items.
22754 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
22756 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22757 it's not optimized away by whole-program optimization.
22758 (message_enable_multibyte, free_misc): Remove.
22759 (catchlist, handlerlist, mark_backtrace):
22760 Declare only if BYTE_MARK_STACK.

22769 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
22770 (mark_backtrace): Define only if BYTE_MARK_STACK.
22771 * xdisp.c (message_enable_multibyte): Now static.
22773 Declare Lisp_Object Q* variables to be 'static' if not exported.
22774 This makes it easier for human readers (and static analyzers)
22775 to see whether these variables are used from other modules.
22776 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
22777 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
22778 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

22786 Remove decls of unexported vars.
22787 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22789 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22791 Make Emacs functions such as Fatom 'static' by default.
22792 This makes it easier for human readers (and static analyzers)
22793 to see whether these functions can be called from other modules.
22794 DEFUN now defines a static function. To make the function external
22795 so that it can be used in other C modules, use the new macro DEFUE.
22796 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22797 (Finit_image_library):
22798 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22799 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22800 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22801 Remove decls, since these functions are now static.
22802 (Funintern, Fget_internal_run_time): New decls, since these functions
22803 were already external.
22805 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22806 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

22812 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22813 Mark functions with DEFUE instead of DEFUN,
22814 if they are used in other modules.
22815 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22816 decls for now-static functions.
22817 * buffer.h (Fdelete_overlay): Remove decl.
22818 * callproc.c (Fgetenv_internal): Mark as internal.
22819 * composite.c (Fremove_list_of_text_properties): Remove decl.

22825 (Funintern): Remove extern decl; now in .h file where it belongs.
22826 * fileio.c (Fmake_symbolic_link): New forward static decl.
22827 * image.c (Finit_image_library): New forward static decl.
22828 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22829 * intervals.h (Fprevious_property_change):
22830 (Fremove_list_of_text_properties): Remove decls.
22831 * keyboard.c (Fthis_command_keys): Remove decl.
22832 (Fcommand_execute): New forward static decl.
22833 * keymap.c (Flookup_key): New forward static decl.
22834 (Fcopy_keymap): Now static.
22835 * keymap.h (Flookup_key): Remove decl.
22836 * process.c (Fget_process): New forward static decl.
22837 (Fprocess_datagram_address): Mark as internal.

22848 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22850 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22853 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22855 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22856 when at ZV. (Bug#8487)
22858 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22860 * charset.c (Fclear_charset_maps): Use xfree instead of free.

22864 * termcap.c (tgetent): Likewise.
22865 * xfns.c (x_default_font_parameter): Likewise.
22866 * xsettings.c (read_and_apply_settings): Likewise.
22868 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22869 (overrun_check_free): Protoize.
22871 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22873 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22874 since callers should never pass a negative size.
22875 Change the signature to match that of plain 'read' and 'write'; see
22876 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22877 * lisp.h: Update prototypes of emacs_write and emacs_read.
22879 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22881 * xdisp.c (redisplay_window): Don't try to determine the character
22882 position of the scroll margin if the window start point w->startp
22883 is outside the buffer's accessible region. (Bug#8468)
22885 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22887 Fix write-region and its subroutines for buffers > 2GB.
22888 * fileio.c (a_write, e_write): Modify declaration of arguments and
22889 local variables to support buffers larger than 2GB.
22890 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22892 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22893 argument, local variables, and return value.
22895 * lisp.h: Update prototypes of emacs_write and emacs_read.
22897 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22899 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22901 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22903 Fix more problems found by GCC 4.6.0's static checks.
22905 * xdisp.c (vmessage): Use a better test for character truncation.
22907 * charset.c (load_charset_map): <, not <=, for optimization,
22908 and to avoid potential problems with integer overflow.
22909 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22910 * casetab.c (set_identity, shuffle): Likewise.
22911 * editfns.c (Fformat): Likewise.
22912 * syntax.c (skip_chars): Likewise.
22914 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22915 This also lets GCC 4.6.0 generate slightly better loop code.
22917 * callint.c (Fcall_interactively): <, not <=, for optimization.
22918 (Fcall_interactively): Count the number of arguments produced,
22919 not the number of arguments given. This is simpler and lets GCC
22920 4.6.0 generate slightly better code.
22922 * ftfont.c: Distingish more carefully between FcChar8 and char.
22923 The previous code passed unsigned char * to a functions like
22924 strlen and xstrcasecmp that expect char *, which does not
22925 conform to the C standard.
22926 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22927 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22928 char * when the C standard requires it.
22930 * keyboard.c (read_char): Remove unused var.
22932 * eval.c: Port to Windows vsnprintf (Bug#8435).
22933 Include <limits.h>.
22934 (SIZE_MAX): Define if the headers do not.
22935 (verror): Do not give up if vsnprintf returns a negative count.
22936 Instead, grow the buffer. This ports to Windows vsnprintf, which
22937 does not conform to C99. Problem reported by Eli Zaretskii.
22938 Also, simplify the allocation scheme, by avoiding the need for
22939 calling realloc, and removing the ALLOCATED variable.
22941 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22943 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22944 But keep the doprint source code for now, as we might revamp it
22945 and use it again (Bug#8435).
22946 * lisp.h (doprnt): Remove.
22947 * Makefile.in (base_obj): Remove doprnt.o.
22948 * deps.mk (doprnt.o): Remove.
22950 error: Print 32- and 64-bit integers portably (Bug#8435).
22951 Without this change, on typical 64-bit hosts error ("...%d...", N)
22952 was used to print both 32- and 64-bit integers N, which relied on
22953 undefined behavior.
22954 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22955 * lisp.h (error, verror): Mark as printf-like functions.
22956 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22957 Report overflow in size calculations when allocating printf buffer.
22958 Do not truncate output string at its first null byte.
22959 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22960 Truncate the output at a character boundary, since vsnprintf does not
22962 * charset.c (check_iso_charset_parameter): Convert internal
22963 character to string before calling 'error', since %c now has the
22965 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22966 overflow when computing char to be passed to 'error'. Do not
22967 pass Lisp_Object to 'error'; pass the integer instead.
22968 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22969 formatted with plain %d.
22971 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22973 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22975 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22977 * xterm.c (x_catch_errors): Remove duplicate declaration.
22979 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22981 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22983 2011-04-10 Jim Meyering <meyering@redhat.com>
22985 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22986 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22987 return ssize_t not "int", and use size_t as the buffer length.
22988 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22989 * gnutls.h: Update declarations.
22990 * process.c (read_process_output): Use ssize_t, to match.
22991 (send_process): Likewise.
22993 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22995 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22997 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22999 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
23000 Use unsigned char, to match FcChar8 type definition.
23002 * xterm.c (handle_one_xevent):
23003 * xmenu.c (create_and_show_popup_menu):
23004 * xselect.c (x_decline_selection_request)
23005 (x_reply_selection_request): Avoid type-punned deref of X events.
23007 2011-04-09 Eli Zaretskii <eliz@gnu.org>
23009 Fix some uses of `int' instead of EMACS_INT.
23010 * search.c (string_match_1, fast_string_match)
23011 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
23012 (scan_buffer, find_next_newline_no_quit)
23013 (find_before_next_newline, search_command, Freplace_match)
23014 (Fmatch_data): Make some `int' variables be EMACS_INT.
23016 * xdisp.c (display_count_lines): 3rd argument and return value now
23017 EMACS_INT. All callers changed.
23018 (pint2hrstr): Last argument is now EMACS_INT.
23020 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
23021 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
23022 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

23025 (decode_coding_ccl, decode_coding_charset)
23026 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

23028 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
23029 <char_offset, last_offset>: Declare EMACS_INT.

23060 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
23062 * keyboard.c (read_char): Call Lisp function help-form-show,
23063 instead of using internal_with_output_to_temp_buffer.
23064 (Qhelp_form_show): New var.
23065 (syms_of_keyboard): Use DEFSYM macro.
23067 * print.c (internal_with_output_to_temp_buffer): Function deleted.

23080 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
23082 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
23084 Fix more problems found by GCC 4.6.0's static checks.
23086 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
23088 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
23090 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
23092 * xdisp.c (vmessage): Mark as a printf-like function.
23094 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

23101 to system-supplied API.
23103 * eval.c (Fsignal): Remove excess argument to 'fatal'.
23105 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
23106 This avoids several warnings with gcc -Wstrict-overflow.
23107 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
23108 directly, rather than having caller test rule sign. This avoids
23109 some unnecessary tests.
23110 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
23111 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
23112 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
23114 * xfont.c (xfont_text_extents): Remove var that was set but not used.
23115 (xfont_open): Avoid unnecessary tests.
23117 * composite.c (composition_gstring_put_cache): Use unsigned integer.
23119 * composite.h, composite.c (composition_gstring_put_cache):
23120 Use EMACS_INT, not int, for length.
23122 * composite.h (COMPOSITION_DECODE_REFS): New macro,
23123 breaking out part of COMPOSITION_DECODE_RULE.
23124 (COMPOSITION_DECODE_RULE): Use it.
23125 * composite.c (get_composition_id): Remove unused local vars,
23126 by using the new macro.
23128 * textprop.c (set_text_properties_1): Change while to do-while,
23129 since the condition is always true at first.
23131 * intervals.c (graft_intervals_into_buffer): Mark var as used.
23132 (interval_deletion_adjustment): Return unsigned value.
23135 * process.c (list_processes_1, create_pty, read_process_output):
23136 (exec_sentinel): Remove vars that were set but not used.
23137 (create_pty): Remove unnecessary "volatile"s.
23138 (Fnetwork_interface_info): Avoid possibility of int overflow.
23139 (read_process_output): Do adaptive read buffering even if carryover.
23140 (read_process_output): Simplify nbytes computation if buffered.
23142 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
23144 * syntax.c (scan_words): Remove var that was set but not used.
23145 (update_syntax_table): Use unsigned instead of int.
23147 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

23151 * print.c (print_error_message): Avoid int overflow.
23153 * font.c (font_list_entities): Redo for clarity,
23154 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
23156 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
23157 (font_score): Avoid potential overflow in diff calculation.
23159 * fns.c (substring_both): Remove var that is set but not used.
23160 (sxhash): Redo loop for clarity and to avoid wraparound warning.
23162 * eval.c (funcall_lambda): Rename local to avoid shadowing.
23164 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
23165 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
23166 can always succeed if overflow has undefined behavior.
23168 * search.c (boyer_moore, wordify): Remove vars set but not used.
23169 (wordify): Omit three unnecessary tests.
23171 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
23172 All callers changed. This avoids the need for an unused var.
23174 * casefiddle.c (casify_region): Remove var that is set but not used.
23176 * dired.c (file_name_completion): Remove var that is set but not used.
23178 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23180 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23181 (Finsert_file_contents): Remove unnecessary code checking fd.
23183 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23184 Check for integer overflow on size calculations.
23186 * buffer.c (Fprevious_overlay_change): Remove var that is set
23189 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23190 Remove vars that are set but not used.
23191 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23192 (timer_check_2): Mark vars as initialized.
23194 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23196 * image.c (lookup_image): Remove var that is set but not used.
23197 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23199 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23200 that are set but not used.
23202 * xfns.c (make_invisible_cursor): Don't return garbage
23203 if XCreateBitmapFromData fails (Bug#8410).
23205 * xselect.c (x_get_local_selection, x_handle_property_notify):
23206 Remove vars that are set but not used.
23208 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
23209 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
23211 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
23212 Remove var that is set but not used.
23213 (scroll_bar_windows_size): Now size_t, not int.
23214 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23215 Check for overflow.
23217 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23218 (map_tty_color) [!defined MSDOS]: Likewise.
23220 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23222 * coding.c: Remove vars that are set but not used.
23223 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
23224 All callers changed.
23225 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
23226 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
23227 (decode_coding_charset): Remove vars that are set but not used.
23229 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
23230 that is set but not used.
23232 * print.c (print_object): Remove var that is set but not used.
23234 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23235 The gnulib version avoids calling malloc in the usual case,
23236 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23237 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23238 * filelock.c (current_lock_owner): Likewise.
23239 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23240 * sysdep.c: Include allocator.h, careadlinkat.h.
23241 (emacs_no_realloc_allocator): New static constant.
23242 (emacs_readlink): New function.
23243 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23244 ../lib/careadlinkat.h.
23246 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23248 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
23249 first non-nil return value).
23251 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
23253 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
23254 if not defined (Bug#8403).
23256 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23258 * xdisp.c (display_count_lines): Remove parameter `start',
23259 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23260 (get_char_face_and_encoding): Remove parameter `multibyte_p',
23261 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

23263 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
23264 and thereabouts. All callers changed.
23265 (get_per_char_metric): Remove parameter `f', unused since
23266 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
23268 2011-04-02 Jim Meyering <meyering@redhat.com>
23270 do not dereference NULL upon failed strdup
23271 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23272 (ns_get_family): Likewise.
23274 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23276 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23278 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23280 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23283 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23285 Add lexical binding.
23287 * window.c (Ftemp_output_buffer_show): New fun.
23288 (Fsave_window_excursion):
23289 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
23291 * lread.c (lisp_file_lexically_bound_p): New function.
23292 (Fload): Bind Qlexical_binding.
23293 (readevalloop): Remove `evalfun' arg.
23294 Bind Qinternal_interpreter_environment.
23295 (Feval_buffer): Bind Qlexical_binding.
23296 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23298 (syms_of_lread): Declare `lexical-binding'.
23300 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23302 * keyboard.c (eval_dyn): New fun.
23303 (menu_item_eval_property): Use it.
23305 * image.c (parse_image_spec): Use Ffunctionp.
23307 * fns.c (concat, mapcar1): Accept byte-code-functions.
23309 * eval.c (Fsetq): Handle lexical vars.
23310 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23311 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23312 (FletX, Flet): Obey lexical binding.
23313 (Fcommandp): Handle closures.
23314 (Feval): New `lexical' arg.
23315 (eval_sub): New function extracted from Feval. Use it almost
23316 everywhere where Feval was used. Look up vars in lexical env.
23318 (Ffunctionp): Move from subr.el.
23319 (Ffuncall): Handle closures.
23320 (apply_lambda): Remove `eval_flags'.
23321 (funcall_lambda): Handle closures and new byte-code-functions.
23322 (Fspecial_variable_p): New function.
23323 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23324 but without exporting it to Lisp.
23326 * doc.c (Fdocumentation, store_function_docstring):
23327 * data.c (Finteractive_form): Handle closures.
23329 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23332 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23334 (exec_byte_code): New function extracted from Fbyte_code to handle new
23335 calling convention for byte-code-functions. Add new byte-codes.
23337 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
23339 * alloc.c (Fmake_symbol): Init new `declared_special' field.
23341 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23343 * xdisp.c (redisplay_internal): Fix prototype.
23345 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23347 * xdisp.c (SCROLL_LIMIT): New macro.
23348 (try_scrolling): Use it when setting scroll_limit.
23349 Limit scrolling to 100 screen lines.
23350 (redisplay_window): Even when falling back on "recentering",
23351 position point in the window according to scroll-conservatively,
23352 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23354 (try_scrolling): When point is above the window, allow searching
23355 as far as scroll_max, or one screenful, to compute vertical
23356 distance from PT to the scroll margin position. This prevents
23357 try_scrolling from unnecessarily failing when
23358 scroll-conservatively is set to a value slightly larger than the
23359 window height. Clean up the case of PT below the margin at bottom
23360 of window: scroll_max can no longer be INT_MAX. When aggressive
23361 scrolling is in use, don't let point enter the opposite scroll
23362 margin as result of the scroll.
23363 (syms_of_xdisp) <scroll-conservatively>: Document the
23364 threshold of 100 lines for never-recentering scrolling.
23366 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23368 * dispextern.h (move_it_by_lines):
23369 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
23370 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
23371 (message_log_check_duplicate): Remove parameters `prev_bol' and
23372 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23373 (redisplay_internal): Remove parameter `preserve_echo_area',
23374 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23376 * indent.c (Fvertical_motion):
23377 * window.c (window_scroll_pixel_based, Frecenter):
23378 Don't pass `need_y_p' to `move_it_by_lines'.
23380 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23382 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23383 steal a few bits to be more compact.
23384 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23385 Remove unneeded casts.
23387 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23389 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23391 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23392 binding" message (bug#7967).
23394 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23396 Fix more problems found by GCC 4.6.0's static checks.
23398 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23399 Remove unused local var.
23401 * editfns.c (Fmessage_box): Remove unused local var.
23403 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23404 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23405 Omit unused local vars.
23406 * window.c (shrink_windows): Omit unused local var.
23407 * menu.c (digest_single_submenu): Omit unused local var.
23408 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23409 Omit unused local var.
23411 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23412 Don't assume string length fits in int.
23413 (keyremap_step, read_key_sequence): Use size_t for sizes.
23414 (read_key_sequence): Don't check last_real_key_start redundantly.
23416 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
23417 instead of alloca (Bug#8344).
23419 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23420 (Fbacktrace_frame): Don't assume nframes fits in int.
23422 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
23424 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
23427 * term.c (produce_glyphless_glyph): Remove unnecessary test.
23429 * cm.c (calccost): Turn while-do into do-while, for clarity.
23431 * keyboard.c (syms_of_keyboard): Use the same style as later
23432 in this function when indexing through an array. This also
23433 works around GCC bug 48267.
23435 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23437 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23439 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23440 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23442 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23443 This avoids undefined behavior on integer overflow, and is a bit
23444 more convenient anyway since it is compared to a size_t variable.
23446 Variadic C functions now count arguments with size_t, not int.
23447 This avoids an unnecessary limitation on 64-bit machines, which
23448 caused (substring ...) to crash on large vectors (Bug#8344).
23449 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
23450 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
23451 All variadic functions and their callers changed accordingly.

23458 * fns.c (concat): Likewise.
23459 * frame.c (x_set_frame_parameters): Likewise.
23460 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23461 0 if not found, not -1. All callers changed.
23463 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23464 (stack_copy_size): Now size_t, not int.
23465 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23467 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
23469 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
23470 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
23471 All callers changed.
23473 * lisp.h (multibyte_char_to_unibyte):
23474 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
23475 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
23476 * character.h (CHAR_TO_BYTE8):
23477 * cmds.c (internal_self_insert):
23478 * editfns.c (general_insert_function):
23479 * keymap.c (push_key_description):
23480 * search.c (Freplace_match):
23481 * xdisp.c (message_dolog, set_message_1): All callers changed.
23483 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
23485 * keyboard.c (safe_run_hook_funcall): New function.
23486 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23487 don't set the hook to nil, but remove the offending function instead.
23488 (Qcommand_hook_internal): Remove, unused.
23489 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define

23670 * buffer.c (Fkill_all_local_variables):
23671 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23673 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23674 unconditionally since it does the check itself.
23676 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23678 Fix more problems found by GCC 4.5.2's static checks.
23680 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23681 the first time through the loop, since we know p0 < p1 then.
23682 This also avoids a gcc -Wstrict-overflow warning.
23684 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23685 leading to a memory leak, possible in functions like
23686 load_charset_map_from_file that can allocate an unbounded number
23687 of objects (Bug#8318).
23689 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23690 that could (at least in theory) be that large.
23692 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23693 This is less likely to overflow, and avoids undefined behavior if
23694 overflow does occur. All callers changed. Use strtoul to scan
23695 for the unsigned long integer.
23696 (pint2hrstr): Simplify and tune code slightly.

23712 * process.c (Fmake_network_process): Use socklen_t, not int,
23713 where POSIX says socklen_t is required in portable programs.
23714 This fixes a porting bug on hosts like 64-bit HP-UX, where
23715 socklen_t is wider than int (Bug#8277).
23716 (Fmake_network_process, server_accept_connection):
23717 (wait_reading_process_output, read_process_output):
23720 * process.c: Rename or move locals to avoid shadowing.

23730 Make tparam.h and terminfo.c consistent.
23731 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23732 Include tparam.h instead, since it declares them.
23733 * cm.h (PC): Remove extern decl; tparam.h now does this.
23734 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23735 * terminfo.c: Include tparam.h, to check interfaces.
23736 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23737 (tparam): Adjust signature to match interface in tparam.h;
23738 this removes some undefined behavior. Check that outstring and len
23739 are zero, which they always are with Emacs.
23740 * tparam.h (PC, BC, UP): New extern decls.
23742 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23743 (xftfont_open): Rename locals to avoid shadowing.

23761 (composition_update_it): Mark var as initialized.
23762 (find_automatic_composition): Mark vars as initialized,
23763 with a FIXME (Bug#8290).

23769 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23770 to avoid shadowing.

23782 Fix pointer signedness.
23783 (alsa_choose_format): Remove unused local var.
23784 (wav_play): Initialize a variable to 0, to prevent undefined
23785 behavior (Bug#8278).
23787 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23789 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23791 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23792 clobbering (Bug#8298).
23793 * sysdep.c (sys_subshell): Likewise.
23794 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23796 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23797 This should get cleaned up, so that child_setup has the
23798 same signature on all platforms.
23800 * callproc.c (call_process_cleanup): Now static.
23801 (relocate_fd): Rename locals to avoid shadowing.
23803 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23805 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23806 not to be necessary, and produces flickering.
23808 2011-03-20 Glenn Morris <rgm@gnu.org>
23810 * config.in: Remove file.
23812 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

23863 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23865 * deps.mk (unexalpha.o): Remove; unused.

23944 * data.c (Findirect_variable): Name an expression, to avoid
23945 gcc -Wbad-function-cast warning.
23946 (default_value, arithcompare, arith_driver, arith_error): Now static.

23961 (GC_STRING_CHARS): Remove; not used.
23962 (Fmemory_limit): Cast sbrk's returned value to char *.
23964 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23965 avoids undefined behavior in theory.
23967 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23969 Use functions, not macros, for up- and down-casing (Bug#8254).
23970 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23971 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23972 to use the following functions instead of these macros.
23973 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23974 EMACS_INT, since callers assume the returned value fits in int.
23975 (upcase1): Likewise, for UPCASE_TABLE.
23976 (uppercasep, lowercasep, upcase): New static inline functions.
23977 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23978 the race-condition problem in the old DOWNCASE.
23980 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

23986 which gcc can warn about.
23987 (regex_compile, re_match_2_internal): Mark locals as initialized.
23988 (RETALLOC_IF): Define only if needed.
23989 (WORDCHAR_P): Likewise. This one is never needed, but is used
23990 only in a comment talking about a compiler bug, so put inside
23991 the #if 0 of that comment.
23992 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23993 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23996 * search.c (boyer_moore): Rename locals to avoid shadowing.
23997 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

24019 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
24020 New macros, so that the caller can use some names other than
24021 gcpro1, gcpro2, etc.
24022 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
24024 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
24025 argument, for consistency with GCPRO2_VAR, etc: it is now the
24026 prefix of the variable, not the variable itself. All uses
24028 * dired.c (directory_files_internal, file_name_completion):
24029 Rename locals to avoid shadowing.
24031 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
24032 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
24033 dired.c's scmp function, had undefined behavior.
24034 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
24035 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
24036 * buffer.h: ... to here, because these macros use current_buffer,
24037 and the new implementation with inline functions needs to have
24038 current_buffer in scope now, rather than later when the macros
24040 (downcase, upcase1): New static inline functions.
24041 (DOWNCASE, UPCASE1): Reimplement using these functions.
24042 This avoids undefined behavior in expressions like
24043 DOWNCASE (x) == DOWNCASE (y), which previously suffered
24044 from race conditions in accessing the global variables
24045 case_temp1 and case_temp2.
24046 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
24047 * lisp.h (case_temp1, case_temp2): Remove their decls.
24048 * character.h (ASCII_CHAR_P): Move from here ...
24049 * lisp.h: ... to here, so that the inline functions mentioned
24050 above can use them.
24052 * dired.c (directory_files_internal_unwind): Now static.
24054 * fileio.c (file_name_as_directory, directory_file_name):
24055 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
24057 (file_name_as_directory): Use const pointers when appropriate.
24058 (Fexpand_file_name): Likewise. In particular, newdir might
24059 point at constant storage, so make it a const pointer.
24060 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
24061 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
24063 (Fset_file_times, Finsert_file_contents, auto_save_error):

24068 to avoid shadowing.
24070 * marker.c (bytepos_to_charpos): Remove; unused.
24072 * lisp.h (verify_bytepos, count_markers): New decls,
24073 so that gcc does not warn that these functions aren't declared.
24075 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
24076 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
24077 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
24078 (copy_text): Remove unused local var.
24080 * filelock.c (within_one_second): Now static.
24081 (lock_file_1): Rename local to avoid shadowing.
24083 * buffer.c (fix_overlays_before): Mark locals as initialized.
24084 (fix_start_end_in_overlays): Likewise. This function should be
24085 simplified by using pointers-to-pointers, but that's a different
24087 (switch_to_buffer_1): Now static.
24088 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
24089 (report_overlay_modification): Rename locals to avoid shadowing.
24091 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
24092 Fix pointer signedness issue.
24093 (sys_subshell): Mark local as volatile if checking for lint,
24094 to suppress a gcc -Wclobbered warning that does not seem to be right.
24095 (MAXPATHLEN): Define only if needed.
24097 * process.c (serial_open, serial_configure): Move decls from here ...
24098 * systty.h: ... to here, so that they can be checked.
24100 * fns.c (get_random, seed_random): Move extern decls from here ...
24101 * lisp.h: ... to here, so that they can be checked.
24103 * sysdep.c (reset_io): Now static.
24104 (wait_for_termination_signal): Remove; unused.
24106 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

24109 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
24110 (DENSE_TABLE_SIZE): Remove; unused.
24111 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
24112 (describe_map_tree):
24113 Rename locals to avoid shadowing.
24115 * keyboard.c: Declare functions static if they are not used elsewhere.

24263 1152921504606846976) returns the obviously-bogus value (-948597
24264 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
24265 reports time overflow. See
