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

663 * xdisp.c (row_for_charpos_p): New function, with code of
664 cursor_row_p, but accepts an additional argument CHARPOS instead
665 of using a hardcoded PT.
666 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
667 (row_containing_pos): Call row_for_charpos_p instead of partially
668 doing the same. Fixes cursor positioning under longlines-mode
669 when longlines-show-effect includes more than one newline, when
670 moving the cursor vertically up.

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

744 (x_get_monitor_attributes_xinerama): New functions.
745 (Fx_display_monitor_attributes_list): New primitive.
746 (syms_of_xfns): Defsubr it.
748 * xterm.h (x_display_info): Add Xatom_net_workarea and
749 Xatom_net_current_desktop.
751 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
752 and dpyinfo->Xatom_net_current_desktop.
754 2013-05-06 Eli Zaretskii <eliz@gnu.org>
756 * xdisp.c (pos_visible_p): Use the special code for finding the
757 beginning of a display property or overlay for any "replacing"
758 display property, not just for display strings. This solves
759 incorrect reporting of position by posn-at-point. (Bug#14241)
761 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
763 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
764 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
765 Verify that ElfW (Half) fits in int.
766 (fatal): Use same signature as lisp.h.
767 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
768 configure and build with -DUNEXELF_DEBUG without worrying about
769 other modules that use DEBUG.
770 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
771 possibly-wide integers now uses it instead of plain fprintf.
772 (entry_address): New function, which avoids problems with 32-bit
773 overflow on 64-bit hosts.
774 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
775 (round_up): Don't assume the remainder fits in int.
776 (find_section): Use bool for boolean. Simplify debug code.
777 (unexec): Don't assume file sizes fit in int or size_t.
778 Omit unnecessary trailing newline in 'fatal' format.
779 Use strerror rather than outputting decimal error number.
780 Remove unused code when emacs is not defined;
781 this file relies on Emacs now.
782 Don't assume e_phnum and e_shnum are positive.
784 * regex.c: Fix problems when DEBUG is defined.
785 (extract_number, extract_number_and_incr): Define regardless of
786 whether DEBUG is defined; that's simpler and makes the code less
787 likely to go stale in the normal case when DEBUG is not defined.
788 Return int rather than taking an int * arg. All callers changed.
789 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
790 Remove, replacing with ...
791 (DEBUG_PRINT): New macro. All callers changed.
792 (DEBUG_COMPILES_ARGUMENTS): New macro.
793 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
794 (print_compiled_pattern, print_double_string) [DEBUG]:
795 Use prototype rather than old-style definition.
796 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
797 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
798 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
799 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
800 Don't assume ptrdiff_t, size_t, and long are the same width as int.
801 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
802 This matters only when DEBUG is defined.
804 2013-05-05 Eli Zaretskii <eliz@gnu.org>
806 * xdisp.c (set_iterator_to_next): Set the
807 ignore_overlay_strings_at_pos_p flag only if we are _really_
808 iterating over an overlay string, as indicated by the
809 current.overlay_string_index member. (Bug#14306)
811 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
813 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
814 to where it is used, to avoid autorelease issues (Bug#14050).
816 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
818 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
819 * fileio.c (syms_of_fileio): Implement this.
820 * filelock.c (create_lock_file): If symbolic links don't work, so
821 we use a regular file as a lock file, do not fsync the lock file;
824 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
826 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.
827 (syms_of_minibuf): Adjust accodingly.
829 * callint.c (Fcall_interactively): Adjust calls accordingly.
831 2013-05-04 Eli Zaretskii <eliz@gnu.org>
833 * dispextern.h (WINDOW_WANTS_HEADER_LINE_P): Verify that
834 w->contents is a buffer before computing everything else.
835 Use parentheses to disambiguate last part of the condition.
837 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
838 assertion violations. (Bug#14062)
840 2013-05-01 David Reitter <david.reitter@gmail.com>
842 * nsfns.m (ns_tooltip): Initialize.
844 2013-04-28 Eli Zaretskii <eliz@gnu.org>
846 * coding.c (decode_coding_gap): Don't remove the character before
847 a newline unless it's a CR character. (Bug#14287)
849 2013-04-28 Dan Nicolaescu <dann@gnu.org>
851 * dispextern.h (struct face): Move enum face_underline_type
852 earlier so that bitfields can be in the same word.
854 2013-04-28 Jan Djärv <jan.h.d@swipnet.se>
856 * nsfns.m (handlePanelKeys): New function.
857 (EmacsOpenPanel:performKeyEquivalent:)
858 (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle
859 arrows/function/control and copy/paste keys (Bug#14296).
861 2013-04-27 Juri Linkov <juri@jurta.org>
863 * callint.c (Fcall_interactively): Call `Qread_number' for
864 interactive code letter `n' instead of using duplicate code.
867 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
869 * systime.h (make_timeval): Declare as 'const'.
871 2013-04-27 Kenichi Handa <handa@gnu.org>
873 * font.c (font_open_entity): Always open a font of manageable
876 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
878 Port better to AIX (Bug#14258).
879 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
882 2013-04-24 Kenichi Handa <handa@gnu.org>
884 * coding.c (decode_coding_iso_2022): When an invalid escape
885 sequence is encountered, reset the invocation and designation
886 status to the safest one.
888 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
890 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
891 Without this fix, "make distclean" leaves stamp-h1 behind.
893 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
895 * w32fns.c (w32_fullscreen_rect): New function to compute the
896 window rectangle for the given fullscreen mode.
897 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
898 longer tunes the window size. This keeps the window's edges flush
899 with the screen and allows the taskbar to hide itself in fullboth.
901 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
902 window decorations and uses the entire screen.
904 * w32term.h (w32_fullscreen_rect) Add prototype.
905 (struct w32_output): Replace normal_width, normal_height,
906 normal_top, and normal_left members with a single normal_placement
908 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):

912 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
914 * minibuf.c (Ftest_completion): Silence compiler warning.
916 2013-04-15 Eli Zaretskii <eliz@gnu.org>
918 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
921 * frame.h (WINDOW_FRAME): Protect macro and its argument with
924 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
925 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
926 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
927 parentheses where appropriate.
929 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
931 * keyboard.c (timer_start_idle): Remove no-longer-used local.
933 2013-04-14 Eli Zaretskii <eliz@gnu.org>
935 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
936 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
937 Mention in the doc string that setting these variables takes
938 effect only after a call to set-window-buffer. (Bug#14200)
940 2013-04-13 Eli Zaretskii <eliz@gnu.org>
942 * indent.c (Fvertical_motion): Don't consider display strings on
943 overlay strings as display strings on the buffer position we
944 started from. This prevents vertical cursor motion from jumping
945 more than one line when there's an overlay string with a display
946 property at end of line.
947 Reported by Karl Chen <Karl.Chen@quarl.org> in
948 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

953 already selected (bug#14191).
955 2013-04-11 Eli Zaretskii <eliz@gnu.org>
957 * window.c (Fwindow_end): Test more flags, including the buffer's
958 last_overlay_modified flag, to determine whether the window's
959 display is really up-to-date. Prevents the function from
960 returning a stale value. (Bug#14170)
961 (Fwindow_line_height): Fix the test for up-to-date-ness of the
964 2013-04-10 Eli Zaretskii <eliz@gnu.org>
966 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
967 garbaged only if it is not already the top frame on its TTY.
968 This prevents flickering due to constant redrawing of TTY frames when
969 there are GUI frames open in the same session. (Bug#13864)
971 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
973 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
974 of marking the idle timers directly.
976 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
978 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
981 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

1009 due to a profiler signal.
1010 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
1011 with these flags. On platforms where special flags are needed
1012 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.

1219 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
1220 (expose_window_tree): Likewise.
1221 Use contents slot, not buffer, where appropriate.
1222 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1223 to avoid deleted windows. Use contents slot instead of buffer.
1224 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:

1443 Use functions and constants to manipulate Lisp_Save_Value objects.
1444 This replaces code that used macros and strings and token-pasting.

1453 (XSAVE_OBJECT): Now functions, not macros.
1454 (STRING_BYTES_BOUND): Now just a macro, not a constant too;

1561 * coding.c (detect_ascii): New function.
1562 (detect_coding): Set coding->head_ascii and coding->eol_seen only

1601 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1602 too so that these builds can use Cygwin's file conversion
1603 functions. (We've been building and linking cygw32.o all along
1604 and just not using it.)
1606 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

1617 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1619 * w32term.c (w32_read_socket): If the Emacs frame is being
1620 activated, call w32fullscreen_hook, to make sure the new frame
1621 dimensions are in effect. (Bug#13937)
1623 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1625 * xdisp.c (init_iterator): Simplify because both character and byte
1626 positions are either specified or -1. Add eassert. Adjust comment.
1627 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1628 character and byte positions can be obtained from marker.

1648 Include <sys/param.h> unconditionally, as that works elsewhere and
1649 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1650 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

1682 common file dialog code.
1684 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which

1890 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1891 * bidi.c (bidi_find_paragraph_start): Likewise.
1892 * indent.c (vmotion): Likewise.
1894 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1896 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1897 * filelock.c: Include <c-ctype.h>.
1898 (MAX_LFINFO): New top-level constant.
1899 (lock_info_type): Remove members pid, boot_time. Add members at,
1900 dot, colon. Change user member to be the entire buffer, not a
1901 pointer. This allows us to handle the case where a foreign
1902 pid or boot time exceeds the local range. All uses changed.
1903 (LINKS_MIGHT_NOT_WORK): New constant.
1904 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1905 (defined_WINDOWSNT): Remove.
1906 (MAKE_LOCK_NAME, file_in_lock_file_name):
1907 Always use .#FILE (not .#-FILE) for the file lock,
1908 even if it is a regular file.
1909 (rename_lock_file): New function.
1910 (create_lock_file): Use it.
1911 (create_lock_file, read_lock_data):
1912 Prefer a symbolic link for the lock file, falling back on a
1913 regular file if symlinks don't work. Do not try to create
1914 symlinks on MS-Windows, due to security hassles. Stick with
1915 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1916 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1917 host may be using a Windowsish file system, and cannot use
1918 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1919 doesn't work. Don't fail merely because of a symlink-contents
1920 length limit in the current file system; fall back on regular
1921 files. Increase the symlink contents length limit to 8 KiB, this
1922 should be big enough for any real use and doesn't crunch the
1924 (create_lock_file, lock_file_1, read_lock_data):
1925 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1926 (lock_file_1): Return error number, not bool. All callers changed.
1927 (ELOOP): New macro, if not already defined.
1928 (read_lock_data): Return size of lock file contents, not Lisp object.
1929 All callers changed. Handle a race condition if some other process
1930 replaces a regular-file lock with a symlink lock or vice versa,
1931 while we're trying to read the lock.
1932 (current_lock_owner): Parse contents more carefully, to help avoid
1933 confusing a regular-file lock with some other application's use
1934 of the file. Check for lock file contents being too long, or
1935 not parsing correctly.
1936 (current_lock_owner, lock_file):
1937 Allow foreign pid and boot times that exceed the local range.
1938 (current_lock_owner, lock_if_free, lock_file):
1939 Simplify allocation of lock file contents.
1940 * w32.c (sys_rename_replace): New function, containing most of
1941 the contents of the old sys_rename.
1942 (sys_rename): Use it.
1943 (fchmod): New dummy function.
1944 * w32.h (sys_rename_replace, fchmod): New decls.
1946 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1948 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1949 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1950 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1951 <dmantipov@yandex.ru>.
1953 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1955 * composite.c (get_composition_id, fill_gstring_header):
1956 Use make_uninit_vector where appropriate.
1957 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1958 * xselect.c (clean_local_selection_data): Likewise.
1960 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1962 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1963 * image.c (imagemagick_load_image): Calculate height and width
1964 after flattening the image, not before.
1966 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1968 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1969 * ftfont.c (ftfont_shape_by_flt): Likewise.
1970 * w32uniscribe.c (uniscribe_shape): Likewise.
1972 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1974 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1975 The old approach, which fell back on DIR/.#FILE.0 through
1976 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1977 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1978 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1979 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1980 because the locking mechanism was never reliable in that case).
1981 This patch fixes this and other bugs discovered by a code
1982 inspection that was prompted by
1983 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1984 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1985 to avoid interoperability problems between the MS-Windows and
1986 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1987 instances of Emacs now ignore each others' locks.
1988 * filelock.c (defined_WINDOWSNT): New constant.
1989 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1990 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1991 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1992 regular files on MS-Windows hosts.
1993 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1994 Use SAFE_ALLOCA to avoid problems with long file names.
1995 (MAX_LFINFO): Now a local constant, not a global macro.
1996 (IS_LOCK_FILE): Remove.
1997 (lock_file_1): Don't inspect errno if symlink call succeeds;
1998 that's not portable.
1999 (lock_file): Document that this function can return if lock
2001 (lock_file): Don't access freed storage.
2003 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
2005 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
2007 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
2009 * textprop.c: Use bool for booleans.
2010 (validate_interval_range, Fadd_text_properties)
2011 (Fremove_text_properties): Prefer bool to int when either works.
2013 2013-03-02 Eli Zaretskii <eliz@gnu.org>
2015 * textprop.c (Fadd_text_properties, Fremove_text_properties):
2016 If the interval tree changes as a side effect of calling
2017 modify_region, re-do processing starting from the call to
2018 validate_interval_range. (Bug#13743)
2020 2013-02-28 Eli Zaretskii <eliz@gnu.org>
2022 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
2025 2013-02-27 Eli Zaretskii <eliz@gnu.org>
2027 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
2028 _SH_DENYRW flag, instead of emacs_open, to deny any other process
2029 access to the lock file until it is written and closed.
2032 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
2034 * callint.c (Qcall_interactively):
2035 * macros.c (Qexecute_kbd_macro):
2038 2013-02-26 Bastien Guerry <bzg@gnu.org>
2040 * window.c (Frecenter): Tiny docstring enhancement.
2042 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
2044 Minor textprop integer cleanup.
2045 * intervals.h, textprop.c (add_text_properties_from_list):
2046 Return void, not int, since nobody uses the return value.
2047 * textprop.c (validate_plist, add_properties, remove_properties)
2048 (Fadd_text_properties):
2049 Don't assume list length fits in int.
2050 (interval_has_all_properties, interval_has_some_properties)
2051 (interval_has_some_properties_list, add_properties, remove_properties)
2052 (Fadd_text_properties, Fremove_text_properties)
2053 (Fremove_list_of_text_properties, text_property_stickiness):
2054 Use bool for booleans.

2056 (Fremove_list_of_text_properties):
2057 Reindent do-while as per GNU style.

2061 Implement CLASH_DETECTION for MS-Windows.
2063 * filelock.c [WINDOWSNT]: Include w32.h.
2064 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
2065 function of that name. Up-case the macro arguments.
2066 (IS_LOCK_FILE): New macro.
2067 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
2068 (create_lock_file): New function, with body extracted from
2070 [WINDOWSNT]: Implement lock files by writing a regular file with
2071 the lock information as its contents.
2072 (read_lock_data): New function, on Posix platforms just calls
2074 [WINDOWSNT]: Read the lock info from the file.
2075 (current_lock_owner): Call read_lock_data instead of calling
2076 emacs_readlinkat directly.
2077 (lock_file) [WINDOWSNT]: Run the file name through
2080 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
2081 just check if the process by that PID exists.
2083 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
2084 also present, as doing so will fail to error out if the file
2087 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
2089 * textprop.c (Fadd_text_properties, Fremove_text_properties)
2090 (Fremove_list_of_text_properties): Skip all of the intervals in
2091 the region between START and END that already have resp. don't
2092 have the requested properties, not just the first one.
2093 Add assertions that the loop afterwards always modifies the
2094 properties. (Bug#13743)

2106 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
2107 (START_FILES): Remove. All uses removed.
2108 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.

2124 * vm-limit.c: Move most of mem-limits.h's contents here.
2125 (data_start): New decl. It's OK if this is approximate,
2126 so simplify-away some unnecessary exactness.
2127 (POINTER): Remove; all uses removed.
2128 (data_space_start): Now char *, to avoid casts.
2129 (exceeds_lisp_ptr): New function, replacing the old

2154 Remove, replacing all uses with C89 equivalents. These old
2155 symbols were present only for porting to pre-C89 platforms.

2278 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2280 Fix AIX port (Bug#13650).
2281 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2282 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2283 was #undeffed earlier, so it cannot be used as a macro here.
2284 Use the constant and not the macro.
2286 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2288 * w32proc.c (new_child): If no vacant slots are found in
2289 child_procs[], make another pass looking for slots whose process
2290 has exited or died. (Bug#13546)

2293 MAXDESC, set errno to EMFILE.
2294 (_sys_read_ahead): Update cp->status when failing to read serial
2295 communications input, so that the status doesn't stay at
2296 STATUS_READ_IN_PROGRESS. (Bug#13546)

2324 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2326 Improve AIX port some more (Bug#13650).
2327 With this, it should be as good as it was in 23.3, though it's
2328 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2329 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2330 * unexaix.c (start_of_text): Remove.
2331 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2332 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2333 (orig_load_scnptr, orig_data_scnptr):
2334 Now off_t, not long, since they are file offsets.
2335 (make_hdr): Use _data, not start_of_data ().
2336 This is the key part of the fix.
2337 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2338 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2340 * pre-crt0.c (data_start): Initialize to 1.
2341 This ports to compilers that optimize the external declaration
2342 'int x = 0;' as if it were 'int x;' to shrink the executable.
2344 Improve AIX port (Bug#13650).
2345 This doesn't fix the bug, but it makes progress: Emacs builds now.
2346 * unexaix.c: Include inttypes.h, stdarg.h.
2347 (report_error, report_error_1): Mark as _Noreturn.
2348 (report_error): Don't report the wrong errno.
2349 (report_error_1): Now varargs. All callers changed.
2350 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2351 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2352 (write_ptr): Use %p to print address rather than %lx and a cast
2353 to unsigned long. Grow buffer a bit, to be safer.
2355 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2357 * bidi.c (bidi_resolve_neutral): After finding the next
2358 non-neutral character, accept NEUTRAL_ON type as well, because
2359 directional control characters, such as LRE and RLE, have their
2360 type converted to that by bidi_resolve_weak. This avoids aborts
2361 when LRE/RLE follows a run of neutrals.
2362 (bidi_move_to_visually_next): Assert that return value of
2363 bidi_peek_at_next_level is non-negative. Negative values will
2366 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2368 Minor getenv-related fixes.

2374 Omit unnecessary cast of getenv or egetenv.
2376 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
2378 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2379 Update dependencies.
2381 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2383 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2385 (display_line): Set w->region_showing to the value of
2386 it->region_beg_charpos, not to -1. This fixes redisplay
2387 optimization when cursor is moved up after M->. (Bug#13623)
2389 (try_scrolling): Scroll text up more if point is too close to ZV
2390 and inside the scroll margin. This makes sure point is moved
2391 outside the scroll margin in these cases.
2393 * window.h (struct window): region_showing can no longer be
2396 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2398 Tune by using memchr and memrchr.
2399 * doc.c (Fsnarf_documentation):
2400 * fileio.c (Fsubstitute_in_file_name):
2401 * search.c (find_newline, scan_newline):
2402 * xdisp.c (pos_visible_p, display_count_lines):
2403 Use memchr and memrchr rather than scanning byte-by-byte.
2404 * search.c (find_newline): Rename from scan_buffer.
2405 Omit first arg TARGET, as it's always '\n'. All callers changed.
2407 Clean up read_key_sequence a tiny bit more.
2408 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2409 (read_key_sequence): Remove unused locals.
2411 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2413 Clean up read_key_sequence a bit; reread active keymaps after first event.
2414 * keyboard.c (read_char, read_char_x_menu_prompt)
2415 (read_char_minibuf_menu_prompt):
2416 Replace nmaps+maps with a single `map' arg.
2417 (follow_key): Operate on a single map.
2418 (active_maps): New function.
2419 (test_undefined): Also return true for nil bindings.
2420 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2421 a single (composed) keymap. Remember `first_event' to choose the right
2422 set of active keymaps. Recompute the set of keymaps after receiving
2423 the first event. Remove GOBBLE_FIRST_EVENT.
2424 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2425 * keyboard.h (read_char): Update declaration.
2426 * lread.c (read_filtered_event): Adjust call to read_char.
2428 2013-02-11 Eli Zaretskii <eliz@gnu.org>
2430 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2431 Don't use the limitation on backwards movement when lines are truncated
2432 in the window. (Bug#13675)
2434 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2436 * marker.c (set_marker_internal): If desired position is passed
2437 as a marker, avoid call to buf_charpos_to_bytepos.
2438 * window.c (Fset_window_point): Omit redundant type checking.
2439 (Fset_window_start): Likewise. Format comment.
2440 (window_scroll_pixel_based): Use set_marker_restricted_both
2441 with character and byte positions obtained from an iterator.
2442 (Fset_window_configuration): Use set_marker_restricted_both.
2443 * xdisp.c (message_dolog): Likewise.
2445 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2447 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2448 When text lines are longer than window's screen lines, don't move back
2449 too far. This speeds up some redisplay operations. (Bug#13675)
2451 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2453 * syntax.c (scan_sexps_forward): Fix byte position calculation
2454 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
2456 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
2458 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
2459 that was not needed.
2461 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2463 Minor hashing refactoring.
2464 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2465 (sxhash_float): Return EMACS_UINT, for consistency with the other
2467 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2468 non-static inline function and therefore can't use static vars.
2469 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2470 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2471 with the other hash functions.
2473 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2475 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2476 XXXXXX part of the temporary file pattern is not downcased even
2477 when w32-downcase-file-names is non-nil. (Bug#13661)
2479 * xdisp.c (decode_mode_spec): Remove handling of %t.
2481 * msdos.c (careadlinkatcwd): Remove.
2483 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2485 * lread.c (skip_dyn_bytes): New function (bug#12598).
2486 (read1): Use it. Use getc instead of READCHAR to read bytes.
2487 (load_each_byte): Remove. Update users.
2489 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2491 * search.c (scan_buffer): Calculate end byte position just once.

2495 (scan_sexps_forward): Record from_byte and avoid redundant
2496 character to byte position calculation ...
2497 (Fparse_partial_sexp): ... here. Break too long line.
2499 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2501 * lisp.h (make_uninit_vector): New function.
2502 * alloc.c (Fvector, Fmake_byte_code):
2503 * ccl.c (Fregister_ccl_program):
2504 * charset.c (Fdefine_charset_internal, define_charset_internal):

2506 * composite.c (syms_of_composite):
2507 * font.c (Fquery_font, Ffont_info, syms_of_font):
2508 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
2509 * ftfont.c (ftfont_shape_by_flt):

2514 * window.c (Fcurrent_window_configuration):
2515 * xfaces.c (Fx_family_fonts):
2516 * xselect.c (selection_data_to_lisp_data): Use it.
2518 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
2520 * coding.c (Fdefine_coding_system_internal): Use AREF where
2521 argument is known to be a vector.
2522 * fns.c (Flocale_info): Likewise for ASET.
2523 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2524 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2526 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2528 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2531 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
2532 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
2533 updateCollectionBehaviour.
2535 * nsterm.m (NEW_STYLE_FS): Remove.
2536 (ns_last_use_native_fullscreen): New variable.
2537 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2538 (x_set_window_size): Do not take title bar and tool bar into account
2539 if isFullscreen returns YES.
2540 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2541 (check_native_fs): New function.
2542 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
2543 (ns_term_init): Remove NEW_STYLE_FS.
2544 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
2545 and tool bar if isFullscreen returns NO.
2546 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2547 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2548 with HAVE_NATIVE_FS.
2549 (window:willUseFullScreenPresentationOptions:): New method.
2550 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
2551 Hide toolbar if not enabled (Bug#13444).

2554 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
2555 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
2556 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
2557 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
2558 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2559 (syms_of_nsterm): Add ns-use-native-fullscreen.
2561 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2563 * fileio.c (Qchoose_write_coding_system): Now static.
2565 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2567 * xdisp.c (window_buffer_changed): region_showing can be negative,
2568 which still means region is being displayed.
2569 (redisplay_internal): Resurrect code that forced redisplay of the
2570 whole window when showing region and the mark has changed.
2571 Record the new mark position to allow redisplay optimizations.
2572 (display_line): If it->region_beg_charpos is non-zero, set the
2573 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2575 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2576 not bitfield of 1 bit.
2578 2013-02-03 Daniel Colascione <dancol@dancol.org>
2580 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2581 daemon mode works on cygw32 when Emacs is installed and not just
2584 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2586 Avoid file time stamp bug on MS-Windows (Bug#13149).
2587 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2588 as FAT32 doesn't update time stamps when truncating them.
2589 Also, check that a file time stamp is not a multiple of 100 ns;
2590 this should catch all instances of the problem on MS-Windows,
2591 as its native file system resolution is 100 ns or worse, and
2592 checking for a non-multiple of 100 ns should impose only a small
2593 overhead on systems with ns resolution.
2595 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2597 Avoid encoding file names on MS-Windows when they need to be run
2598 through dostounix_filename.
2599 * w32.c (normalize_filename): Accept an additional argument
2600 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2601 downcase it even if w32-downcase-file-names is non-nil.
2602 (dostounix_filename): Accept an additional argument MULTIBYTE and
2603 pass it to normalize_filename.
2604 (emacs_root_dir): Adjust.
2606 * msdos.h (dostounix_filename): Adjust prototype.
2608 * w32.h (dostounix_filename): Adjust prototype.
2610 * msdos.c (dostounix_filename): Accept an additional argument and
2612 (init_environment): Adjust callers of dostounix_filename.
2614 * fileio.c (Ffile_name_directory, file_name_as_directory)
2615 (directory_file_name, Fexpand_file_name)
2616 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2618 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2620 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2621 variables, as egetenv is case-insensitive for DOS_NT.
2623 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2624 with an encoded file name.
2626 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2627 Adjust calls to dostounix_filename.
2629 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2631 * unexw32.c (unexec): Adjust call to dostounix_filename.
2633 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2635 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2638 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2641 * callproc.c (Fcall_process): Make sure program name in PATH and
2642 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2643 is passed to exec/spawnve, which fails unless the file-name
2646 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2647 even if w32-quote-process-args is nil.
2649 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2651 Fix timestamp bug when write-region appends nothing (Bug#13149).
2652 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2653 the file's time stamp doesn't change if Emacs happens to write nothing
2654 to the file, and on a buggy file system this could cause Emacs to
2655 incorrectly infer that the file system doesn't have the bug.
2656 Avoid this problem by inhibiting the inference in this case.
2658 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2660 * window.h (struct window): Convert base_line_number, base_line_pos
2661 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2662 Convert region_showing member from Lisp_Object to bitfield.
2663 Remove sequence_number member. Adjust comments.
2664 * window.c (sequence_number): Remove.
2665 (make_window): Initialize column_number_displayed.
2666 * print.c (print_object): Follow the printed representation of
2667 frames and print window pointer to distinguish between windows.
2668 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2669 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2670 (wset_column_number_displayed, wset_region_showing): Remove.
2671 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2672 (try_scrolling, try_cursor_movement, redisplay_window)
2673 (try_window_reusing_current_matrix, try_window_id, display_line)
2674 (display_mode_lines, decode_mode_spec): Adjust users.
2675 * .gdbinit (pwinx): Do not print sequence_number.
2677 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2679 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2680 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2681 * dired.c: Include <fcntl.h>.
2682 (open_directory): New function, which uses open and fdopendir
2683 rather than opendir. DOS_NT platforms still use opendir, though.
2684 (directory_files_internal, file_name_completion): Use it.
2685 (file_attributes): New function, with most of the old Ffile_attributes.
2686 (directory_files_internal, Ffile_attributes): Use it.
2687 (file_attributes, file_name_completion_stat): First arg is now fd,
2688 not dir name. All uses changed. Use fstatat rather than lstat +
2690 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2691 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2692 (emacs_readlinkat): New function, with much of the old
2693 Ffile_symlink_p, but with an fd argument for speed.
2694 It uses readlinkat rather than careadlinkatcwd, so that it
2695 need not assume the working directory.
2696 (Ffile_symlink_p): Use it.
2697 * filelock.c (current_lock_owner): Use emacs_readlinkat
2698 rather than emacs_readlink.
2699 * lisp.h (emacs_readlinkat): New decl.
2700 (READLINK_BUFSIZE, emacs_readlink): Remove.
2701 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2702 (emacs_norealloc_allocator, emacs_readlink): Remove.
2703 This stuff is moved to fileio.c.
2704 * w32.c (fstatat, readlinkat): New functions.
2705 (careadlinkat): Don't check that fd == AT_FDCWD.
2706 (careadlinkatcwd): Remove; no longer needed.
2708 2013-01-31 Glenn Morris <rgm@gnu.org>
2710 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2711 (Fwrite_region): Update for new choose_write_coding_system args.
2712 Move the last piece of choose_write_coding_system here. (Bug#13522)
2713 (syms_of_fileio): Add choose-write-coding-system.
2715 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2717 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2718 (sys_close): Zero out the flags for the file descriptor before
2719 closing it. (Bug#13546)
2721 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2722 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2723 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2726 * w32.c (w32_get_long_filename, init_environment, readlink):
2727 Support file names encoded in DBCS codepages.
2728 (readlink): Use the current file-name-coding-system, not the ANSI
2729 codepage, to decode and handle targets of symlinks.
2731 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2733 * w32.c (opendir): Now accepts a 'const char *'.
2735 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2737 Remove obsolete redisplay code. See the discussion at
2738 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2739 * dispnew.c (preemption_period, preemption_next_check): Remove.
2740 (Vredisplay_preemption_period): Likewise.
2741 (update_frame, update_single_window, update_window, update_frame_1):
2742 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2743 used, following the 2012-06-22 change.
2745 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2747 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2749 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2751 * font.c (num_fonts): Remove the leftover from old
2752 debugging code. Adjust comment style here and there.
2753 * insdel.c (insert_1): Remove.
2754 * lisp.h (insert_1): Remove prototype.
2755 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2757 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2759 * w32.c (max_filename_mbslen): New function.
2760 (normalize_filename, readdir): Use it to detect locales where ANSI
2761 encoding of file names uses a double-byte character set (DBCS).
2762 If a DBCS encoding is used, advance by characters using
2763 CharNextExA, instead of incrementing a 'char *' pointer.
2764 Use _mbslwr instead of _strlwr. (Bug#13515)
2766 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2767 request of memory reservation to 1.7GB. (Bug#13065)

2777 Avoid redundant calls to strlen.
2779 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2781 Drop async_visible and async_iconified fields of struct frame.
2782 This is possible because async input is gone; for details, see
2783 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2784 * frame.h (struct frame): Remove async_visible and async_iconified
2785 members, convert garbaged to unsigned bitfield. Adjust comments.
2786 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2787 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2788 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2789 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2790 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2792 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2793 properly. Likewise for obscured.
2795 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2798 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2800 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2802 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2803 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2805 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2807 * xdisp.c (message2, message2_nolog): Remove functions.
2808 (message3, message3_nolog): Extract nbytes and multibyteness directly
2809 from the string. Change all callers.
2810 (message3_nolog): Don't set message_enable_multibyte since set_message
2811 will reset it anyway.
2812 (message1, message1_nolog): Use message3.
2813 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2814 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2815 (set_message): Drop all but the second arg, which has to be a string.
2816 (set_message_1): Simplify now that we know that a1 is NULL and the
2817 second arg is a string.
2818 * frame.h (struct frame): Remove `message_buf' field.
2819 Use glyphs_initialized_p instead.
2820 (FRAME_MESSAGE_BUF): Remove macro.
2821 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2822 * lisp.h (message2, message2_nolog): Remove declarations.
2823 (message3, message3_nolog): Update declarations.
2824 * keyboard.c (read_char_minibuf_menu_text)
2825 (read_char_minibuf_menu_width): Remove vars.
2826 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2827 to correctly handle multibyte strings.
2828 * frame.c (delete_frame): Don't free message_buf any more.
2829 * editfns.c (message_text, message_length): Remove vars.
2830 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2831 * fileio.c (auto_save_error): Use message3 instead of message2.
2832 * dispnew.c (adjust_frame_message_buffer): Remove function.
2834 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2836 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2837 real estate used for the tool bar and the menu bar.
2839 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2841 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2842 hidden buffer is prepared to modification (Bug#13164).
2844 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2846 * window.h (struct window): Change window_end_valid member from
2847 Lisp_Object to a bitfield. Adjust comments.
2848 (wset_window_end_valid): Remove.
2849 * window.c (adjust_window_count): Clear window_end_valid.
2850 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2851 (Fwindow_line_height, set_window_buffer, Frecenter)
2852 (Fsplit_window_internal, Fdelete_other_windows_internal)
2853 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2854 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2855 * xdisp.c (check_window_end, reconsider_clip_changes)
2856 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2857 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2858 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2860 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2862 * xdisp.c (mark_window_display_accurate): Simplify the loop
2863 assuming that the only one of vchild, hchild or buffer window
2864 slots is non-nil. Call mark_window_display_accurate_1 for
2865 the leaf windows only.
2866 (mark_window_display_accurate_1): Always assume leaf window.
2869 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2871 * emacs.c (Qkill_emacs_hook): Now static.
2873 * fileio.c (Finsert_file_contents): Simplify.
2874 Remove unnecessary assignments and tests.
2876 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2878 * w32.c (acl_set_file): Don't test for errors unless
2879 set_file_security returns FALSE. Avoids spurious errors when
2882 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2884 * fileio.c (Finsert_file_contents): Revert code introduced at
2885 2013-01-18 in favor of the simpler and generally better fix.
2886 Save stack space by removing 'buffer' and reusing 'read_buf'
2889 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2891 * lisp.h (eabs): Define unconditionally (Bug#13419).
2892 The old "#if !defined (eabs)" was an unnecessary revenant of back
2893 when this macro was called "abs". Document 'eabs' better.
2895 2013-01-19 Glenn Morris <rgm@gnu.org>
2897 * fns.c (Frandom): Doc fix.
2899 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2901 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2902 segfault when there are lots of overlays.
2904 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2905 when there are lots of overlays.
2906 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2907 for the details and a way to reproduce.
2909 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2911 * fileio.c: Use O_APPEND to append.
2912 This corresponds better to the natural interpretation of "append",
2913 and avoids the need to open the output file twice, or to invoke
2914 lseek when APPEND is neither nil nor a number.
2915 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2916 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2917 file possibly twice, and lseeking to its end; this avoids the
2918 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2919 at the same time: the combination is never needed and apparently
2920 it doesn't work with DOS_NT.
2922 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2923 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2925 Allow floating-point file offsets.
2926 Problem reported by Vitalie Spinu in
2927 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2928 * fileio.c (emacs_lseek): Remove.
2929 (file_offset): New function.
2930 (Finsert_file_contents, Fwrite_region): Use it.
2932 2013-01-19 Chong Yidong <cyd@gnu.org>
2934 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2935 aborting on Fsignal (Bug#13289).
2937 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2939 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2940 set_file_security as failure due to insufficient privileges.
2941 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2942 (fstat): Return owner and group like 'stat' and 'lstat' do.
2944 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2946 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2947 The bug was observed on Ubuntu operating inside a virtual machine,
2948 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2949 The workaround introduces a race condition on non-buggy hosts,
2950 but it's an unlikely race and anyway there's a nearly identical
2951 nearby race that can't be fixed.
2952 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2954 (Fwrite_region): Test for file system time stamp bug.
2955 (init_fileio): New function.
2956 * lisp.h (init_fileio): Declare it.
2957 * emacs.c (main): Call it.
2959 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2960 and make it more consistent with other stat-failure diagnostics.
2962 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2964 Fix crash when inserting data from non-regular files.
2965 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2966 for the error description produced by valgrind.
2967 * fileio.c (read_non_regular): Rename to read_contents.
2968 Free Lisp_Save_Value object used to pass parameters.
2969 (read_non_regular_quit): Rename to read_contents_quit.
2970 (Finsert_file_contents): Redesign internal file reading loop to adjust
2971 gap and end positions after each read and so help make_gap to work
2972 properly. Do not signal an I/O error too early and so do not leave
2973 not yet decoded characters in a buffer, which was the reason of
2974 redisplay crash. Use list2 to build return value. Adjust comments.
2976 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2978 Close a race when statting and reading files (Bug#13149).
2979 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2980 This avoids a race if the file is renamed between stat and open.
2981 This race is not the problem originally noted in Bug#13149;
2982 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2984 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2986 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
2987 objects, related functions and macros.
2988 (make_save_value): Adjust prototype.
2989 (make_save_pointer): New prototype.
2990 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
2991 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2992 * alloc.c (format_save_value): Rename to make_save_value.
2993 (make_save_pointer): New function.
2994 (record_xmalloc): Use make_save_pointer.
2995 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2996 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2997 Change users of make_save_value to make_save_pointer.
2998 Likewise for format_save_value and make_save_value.

3007 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
3009 * alloc.c (free_save_value): Now static.
3011 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
3013 * keymap.c (map_keymap_internal): Use format_save_value.
3014 (map_keymap_char_table_item): Adjust accordingly.
3015 * fileio.c (non_regular_fd, non_regular_inserted)
3016 (non_regular_nbytes): Remove.
3017 (Finsert_file_contents): Convert trytry to ptrdiff_t.
3018 Use format_save_value to pass parameters to read_non_regular.
3019 (read_non_regular): Use XSAVE_ macros to extract parameters.
3021 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
3023 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
3025 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
3027 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
3028 extraction from any Lisp_Save_Value slot. Add type checking.
3029 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
3030 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
3031 * xselect.c: All users changed.
3033 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

3043 * editfns.c (save_excursion_save): Use format_save_value.
3044 (save_excursion_restore): Use XSAVE_OBJECT.
3046 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
3048 Avoid needless casts with XSAVE_POINTER.
3049 * alloc.c (mark_object) [GC_MARK_STACK]:
3050 * dired.c (directory_files_internal_unwind):
3051 * fileio.c (do_auto_save_unwind):
3052 * gtkutil.c (pop_down_dialog):
3053 * keymap.c (map_keymap_char_table_item):
3054 * lread.c (load_unwind):
3055 * nsmenu.m (pop_down_menu):
3056 * print.c (print_object) [GC_MARK_STACK]:
3057 * xfns.c (clean_up_file_dialog):
3058 * xmenu.c (cleanup_widget_value_tree):
3059 Omit casts between XSAVE_POINTER and a pointer type.
3061 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
3063 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
3064 * eval.c (eval_sub): Protect `form' from being GCed before its
3065 car and cdr becomes protected with the backtrace entry.
3067 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
3069 Make Lisp_Save_Value more versatile storage for up to four objects.
3070 * lisp.h (toplevel): Enumeration to describe types of saved objects.
3071 (struct Lisp_Save_Value): New layout. Adjust comments.
3072 (XSAVE_POINTER): New macro.
3073 (XSAVE_INTEGER): Likewise.
3074 (allocate_misc): Add prototype.
3075 (free_misc): Likewise.
3076 * alloc.c (allocate_misc): Now global.
3077 (free_misc): Likewise. Adjust comment.
3078 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
3079 (free_save_value): Likewise.
3080 (mark_object): Likewise.
3081 * editfns.c (save_excursion_save): Pack everything within
3082 Lisp_Save_Value and so avoid xmalloc.
3083 (save_excursion_restore): Adjust to match new layout. Use free_misc
3084 because we do not allocate extra memory any more. Add eassert.
3085 * print.c (print_object): New code to print Lisp_Save_Value. Do not
3086 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
3087 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
3088 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

3094 (nsfont_draw): Remove disabling of LCD smoothing.
3095 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
3096 Bug#11484 with LCD smoothing on.
3098 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
3100 Fix SIGDANGER handlers, for AIX (Bug#13408).
3101 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
3102 Move handlers here from emacs.c; they were out of place.
3104 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
3106 * xterm.c (syms_of_xterm): Adjust documentation for
3107 scroll-bar-adjust-thumb-portion.
3109 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)

3113 Use variable for MOTIF.
3115 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for GTK.
3117 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

3121 (doCommandBySelector:): Set processingCompose to NO.
3123 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
3124 Remove check for fkeys count > zero, block/unblock fixes the real bug.
3125 (nsfont_list_family): Add block/unblock_input calls.
3126 (nsfont_open): Move block_input earlier. Add unblock_input before early
3128 (nsfont_draw): Add block/unblock_input calls.
3130 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
3132 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
3133 for old_charpos and old_bytepos.
3135 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
3137 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
3138 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
3139 Clear tzvalbuf_in_environ if this workaround is in effect.
3140 Problem and fix reported by Kazuhiro Ito.
3142 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

3151 string cross-reference(s).
3153 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
3155 Avoid unnecessary byte position calculation for the gap movement.
3156 Since all users of move_gap do CHAR_TO_BYTE for other purposes
3157 anyway, all of them should use move_gap_both instead.
3158 * lisp.h (move_gap): Remove prototype.
3159 * insdel.c (move_gap): Remove.
3160 (move_gap_both): Add eassert.
3161 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

3167 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
3169 * term.c (init_tty): Use them instead of rolling our own code.
3170 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
3171 switches from 'signal' to 'pthread_sigmask', which is safer in
3172 multithreaded applications.
3173 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
3174 which has already arranged for that.
3175 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
3176 This is the main part of the bug fix.
3178 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
3180 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around
3181 x_last_font_name (Bug#13403).
3183 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
3185 Omit buffer_slot_type_mismatch and use generic predicates to enforce
3186 the type of per-buffer values where appropriate.
3187 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
3188 predicate, which is how it's really used now. Adjust comment.
3189 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
3190 * buffer.c (buffer_slot_type_mismatch): Remove.
3191 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

3195 left-margin-width, right-margin-width, left-fringe-width,
3196 right-fringe-width, scroll-bar-width and buffer-display-count.
3197 Use Qstringp for default-directory, buffer-file-name,
3198 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
3199 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
3201 * data.c (store_symval_forwarding): Adjust to call the predicate.
3203 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
3205 * w32.c (get_name_and_id, acl_set_file):
3206 * w32term.c (w32fullscreen_hook): Remove unused local variables.
3208 2013-01-09 Dmitry Antipov <dmantipov@yandex.ru>
3210 * lisp.h (make_gap_1): New prototype.
3211 * buffer.h (GAP_BYTES_DFL, GAP_BYTES_MIN): New macros for the special

3215 (syms_of_editfns): Adjust defsubr. Drop commented-out obsolete code.
3216 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
3217 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
3218 (make_gap_1): New function to adjust the gap of any buffer.
3219 * coding.c (coding_alloc_by_making_gap): Use it.
3220 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
3221 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
3223 2013-01-08 Juri Linkov <juri@jurta.org>
3225 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
3226 of (supports :underline (:style wave)). (Bug#13000)
3228 2013-01-08 Aaron S. Hawley <aaron.s.hawley@gmail.com>
3230 * undo.c (Fprimitive_undo): Move to simple.el.

3235 * keyboard.c (echo_add_key): Rename from echo_add_char.
3237 2013-01-06 Chong Yidong <cyd@gnu.org>
3239 * keyboard.c (echo_add_char): New function, factored out from
3240 echo_char. Don't add a space if the previous echo string was
3242 (echo_char): Use it.
3243 (read_key_sequence): When echoing mock input, ensure that the
3244 trailing dash is properly added.
3246 2013-01-05 Eli Zaretskii <eliz@gnu.org>
3248 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
3249 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
3250 digits for buffer positions, before misalignment starts.
3251 Display "0" for integer "object" field.
3252 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
3253 Display the newline glyph more unambiguously.
3255 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3257 * nsterm.m (ns_draw_underwave):
3258 * w32term.c (w32_draw_underwave):
3259 * xterm.c (x_draw_underwave): Make underwave look more triangular
3260 and also degrade gracefully for small fonts. (Bug#13000)
3262 * nsterm.m (ns_draw_text_decoration):
3263 * w32term.c (x_draw_glyph_string):
3264 * xterm.c (x_draw_glyph_string): Don't use previous underline
3265 thickness and position if previous underline type is underwave.
3267 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
3269 * fileio.c (Ffile_acl): Undocument return format.
3271 2013-01-02 Glenn Morris <rgm@gnu.org>
3273 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
3275 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>

3282 * fringe.c (compute_fringe_widths):
3283 * lread.c (read_list):
3284 * minibuf.c (Ftry_completion):
3285 * term.c (tty_ins_del_lines):
3286 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
3287 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
3289 2012-12-31 Eli Zaretskii <eliz@gnu.org>
3291 * w32.c (unsetenv): Set up the string passed to _putenv
3293 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
3294 for the bug this caused.
3296 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
3298 * coding.c (Qmac): Now static.
3300 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
3302 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
3303 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
3304 handlebox_widget. Set toolbar_in_hbox to false/true, set
3305 toolbar_is_packed to true.
3306 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
3307 (update_frame_tool_bar): Check toolbar_is_packed for packing.
3308 Show all on TOOLBAR_TOP_WIDGET.
3309 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
3310 by TOOLBAR_TOP_WIDGET.
3311 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
3312 Check toolbar_is_packed.
3313 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
3314 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3315 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
3317 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3318 (xg_update_menubar): Update title only if
3319 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3320 (xg_update_submenu): Skip tearoff only if
3321 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3322 (xg_initialize): Initialize xg_detached_menus only if
3323 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3325 * xterm.h (struct x_output): Surround handlebox_widget with
3326 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
3327 toolbar_in_hbox is bool.
3329 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
3331 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
3332 (LIBS_GNUSTEP): Define.
3333 (LIBES): Add $(LIBS_GNUSTEP).
3334 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
3336 2012-12-30 Eli Zaretskii <eliz@gnu.org>
3338 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
3339 continuation glyph on a TTY with an indication of an empty line.
3342 2012-12-29 Eli Zaretskii <eliz@gnu.org>
3344 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
3345 file's SELinux context or ACLs successfully set, nil otherwise.
3347 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
3349 * w32proc.c (reader_thread): Avoid passing NULL handles to
3350 SetEvent and WaitForSingleObject.
3352 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
3354 Port EXTERNALLY_VISIBLE to Clang 3.2.
3355 * conf_post.h (__has_attribute): New macro.
3356 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
3358 2012-12-27 Glenn Morris <rgm@gnu.org>
3360 * cygw32.c (Fcygwin_convert_file_name_to_windows)
3361 (Fcygwin_convert_file_name_from_windows): Doc fixes.
3363 2012-12-27 Eli Zaretskii <eliz@gnu.org>
3365 * fileio.c (file_name_as_directory, directory_file_name):
3366 Accept an additional argument MULTIBYTE to indicate whether the input C
3367 came from a multibyte or a unibyte Lisp string; all callers
3368 adjusted. Don't assume the input string is always multibyte.
3370 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
3371 don't ENCODE_FILE them, and return a unibyte string if the input
3373 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
3374 don't assume the input strings will always be multibyte. If the
3375 input strings are multibyte, decode strings obtained from C
3378 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3380 * lisp.h (toplevel): Add two notices to the comment about
3381 defining a new Lisp data type.
3382 * print.c (print_object): If Lisp_Save_Value object's pointer

3385 * alloc.c (valid_lisp_object_p): Adjust comment.
3387 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3389 * keyboard.c (record_asynch_buffer_change): Initialize an event
3390 only if it's really needed.
3391 * frame.h (enum output_method): Remove output_mac member since
3392 it's a leftover from the deleted code.
3393 * frame.c (Fframep): Adjust user here ...
3394 * terminal.c (Fterminal_live_p): ... and here.
3395 * coding.c (Qmac): Now here because it's only used to denote
3396 end-of-line encoding type.
3397 (syms_of_coding): DEFSYM it.
3398 * frame.h (Qmac): Remove duplicated declaration.
3400 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
3402 * window.c (select_window_1): Now static, since it's used only here.
3404 2012-12-25 Eli Zaretskii <eliz@gnu.org>
3406 * window.c (window_body_cols): Subtract display margins from the
3407 window body width on TTYs as well. See
3408 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
3409 for the original report.
3411 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
3413 * xdisp.c (redisplay_window): Remove inner local variable
3414 because the outer shadowed one has the same meaning.
3415 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3417 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3418 (xg_create_tool_bar): Adjust users.
3420 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3422 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3423 * buffer.c (Fget_buffer_create): Use it to set compact field of
3424 struct buffer_text to avoid accessing an uninitialized value
3425 when compact_buffer is called for the first time.
3426 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3427 (Fset_buffer_modified_p): Use buffer_window_count to check
3428 whether the buffer is displayed in some window.
3429 * xdisp.c (message_dolog): Likewise.
3431 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3433 * w32.c (acl_set_file): If setting the file security descriptor
3434 fails, and the new DACL is identical to the existing one, silently
3435 return success. This fixes problems for users backing up their
3436 own files without having the necessary privileges for setting
3437 security descriptors.
3439 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3441 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3442 after WaitForSingleObject returns normally. This expedites reader
3443 thread shutdown when delete_child triggers it.
3444 (reap_subprocess): More accurate commentary for why we call
3445 delete_child only when cp->fd is negative.
3447 * w32.c (sys_close): Do not call delete_child on a subprocess
3448 whose handle is not yet closed. Instead, set its file descriptor
3449 to a negative value, so that reap_subprocess will call
3450 delete_child on that subprocess when its SIGCHLD arrives.
3451 This avoids closing handles used for communications between sys_select
3452 and reader_thread, which doesn't give sys_select a chance to
3453 notice that the process exited and invoke the SIGCHLD handler for
3456 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3458 * nsfns.m (Fns_do_applescript): Run event loop until script has
3459 been executed (Bug#12969).
3460 (ns_run_ascript): Chech as_script for nil, set to nil after
3463 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3465 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3467 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3469 * w32term.c (w32fullscreen_hook): New function.
3470 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3472 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3474 * fileio.c (Finsert_file_contents): Doc fix.
3476 * w32proc.c (new_child, delete_child, find_child_pid): For a
3477 subprocess, consider its slot being in use as long as its process
3478 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3479 slot when a new process is started immediately after killing
3480 another one, without waiting enough time for the first process to
3481 be reaped and resources allocated for it be orderly freed.
3483 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3485 2012-12-21 Chong Yidong <cyd@gnu.org>
3487 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3489 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3491 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3493 * w32.c (get_name_and_id): Always pass NULL as the first argument
3494 of lookup_account_sid. Avoids crashes with UNC file names that
3495 refer to DFS domains, not to specific machine names. (Bug#12621)
3496 Remove now unused argument FNAME; all callers changed.
3497 (get_file_owner_and_group): Remove now unused argument FNAME; all
3500 2012-12-21 Chong Yidong <cyd@gnu.org>
3502 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3503 error for invalid chars, don't check for a nil return value.
3505 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3507 Avoid calls to CHAR_TO_BYTE if byte position is known.
3508 * editfns.c (make_buffer_string_both): Use move_gap_both.
3509 (Fbuffer_string): Use make_buffer_string_both.
3510 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3512 (buf_bytepos_to_charpos): Likewise.
3513 (charpos_to_bytepos): Remove.
3514 * fileio.c (Finsert_file_contents): Use move_gap_both.
3515 * search.c (Freplace_match): Likewise.
3516 * process.c (process_send_region): Likewise. Use convenient
3517 names for byte positions.
3518 * lisp.h (charpos_to_bytepos): Remove prototype.
3519 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3520 * insdel.c (move_gap): Likewise.
3522 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3524 * xdisp.c (redisplay_internal): Remove now-unused local.
3526 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3528 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3529 (redisplay_internal): Don't bother selecting the frame to get the
3530 proper value of frame-local variables (bug#13225).
3532 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3534 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3535 Rename 4th argument since it may be buffer or string. Adjust comment.
3536 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3538 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3540 * coding.c (Fdetect_coding_region): Do not check start and end with
3541 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3542 (code_convert_region): Likewise.
3544 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3546 * w32.c (acl_get_file, acl_set_file): Run the file name through
3547 map_w32_filename, and resolve any symlinks in the file name, like
3549 (acl_set_file): Call revert_to_self, if any privileges were
3552 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3554 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3555 ($(BLD)/w32.$(O)): Update dependencies.
3557 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3559 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3560 propagate redisplay's scrolling (if any) to the right window.
3561 (redisplay_internal): Use ensure_selected_frame.
3562 (display_mode_lines): Complete last fix.
3563 * window.c (select_window_1): New func, extracted from select_window.
3564 (select_window): Use it.
3565 * window.h (select_window_1): Declare.
3567 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3569 Emulate Posix ACL APIs on MS-Windows.
3570 * w32.c: Include sddl.h and sys/acl.h.
3571 (SDDL_REVISION_1): Define if not already defined.
3572 (g_b_init_get_security_descriptor_dacl)
3573 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3574 (g_b_init_is_valid_security_descriptor)
3575 (g_b_init_set_file_security): New static flags.

3587 (acl_free, acl_get_file, acl_set_file): New functions.
3589 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3591 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3593 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3594 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3595 for some of that bug's symptoms can now cause Emacs to abort.
3596 Remove the workaround.
3597 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3598 The bug that caused SIGCHLD to get lost has been fixed, and the
3599 workaround for it can now cause Emacs to abort.
3601 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3603 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3604 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3605 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3607 2012-12-16 Romain Francoise <romain@orebokech.com>
3609 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3610 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3611 and copy ACL entries of file in addition to SELinux context if set.
3612 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3614 * Makefile.in (LIBACL_LIBS): New macro.
3617 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3619 * fileio.c (internal_delete_file): Use bool for boolean.
3621 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3623 Fix bug #13079 on MS-Windows with temp files not being deleted.

3626 (register_child): First argument is now pid_t.
3627 (record_infile, record_pending_deletion): New prototypes.
3629 * w32proc.c (new_child): Initialize input_file and
3630 pending_deletion members of the child.
3631 (delete_child): Delete the child's temporary input file, if any,
3632 that is pending deletion.
3633 (register_child): First argument is now pid_t.
3634 (record_infile, record_pending_deletion): New functions.
3635 (reap_subprocess): Fix a typo in DebPrint string.
3636 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3638 * fileio.c (internal_delete_file): Return an int again: non-zero
3639 if delete-file succeeds, zero otherwise.
3641 * lisp.h (internal_delete_file): Adjust prototype.
3643 * callproc.c (Fcall_process): Don't overwrite infile with result
3645 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3646 asynchronous subprocess, record the name of the input file name,
3648 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3649 delete the file, record it as pending deletion when the subprocess
3652 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3654 * editfns.c [HAVE_PWD_H]: Include grp.h.
3656 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3658 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3660 Fix permissions bugs with setgid directories etc. (Bug#13125)
3661 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3662 to mark it as a placeholder. The old value was often wrong.
3663 The only user of this attribute has been changed to use
3664 file-ownership-preserved-p instead, with its new group arg.
3665 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3667 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
3669 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

3672 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3674 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3675 try to get accurate owner and group information from NT file
3676 security APIs. This is to make most callers of 'stat' and
3677 'lstat', which don't need that information, much faster.
3679 * dired.c (Ffile_attributes) [WINDOWSNT]:
3680 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3681 owner and group information from 'lstat'.
3683 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3685 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3686 as that confuses set-auto-coding, so insist on the head-read
3687 returning the full 1024 bytes. Let lseek compute the tail offset;
3688 less work for us. Do not ignore I/O errors when reading the tail.
3690 * xdisp.c: Minor style fixes.
3691 (init_iterator): Hoist assignment out of if-expression.
3692 (markpos_of_region): Callers now test for sign, not for -1.
3694 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3696 Minor redisplay optimization when the region length is zero.
3697 * xdisp.c (markpos_of_region): New function.
3698 (init_iterator): Do not highlight the region of zero length.
3699 (redisplay_window): Check whether the region is of non-zero length.
3700 (try_cursor_movement): Allow if the region length is zero.
3701 (try_window_reusing_current_matrix, try_window_id): Likewise.
3703 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3705 * search.c (search_buffer): Check the inverse translations of each
3706 character in pattern when the buffer being searched is unibyte.
3709 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>

3718 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3719 Remove unnecessary S_ISLNK test, as (contra the comments) this
3720 function can't copy symlinks. Improve quality of error message
3721 when attempting to copy files that are neither regular files nor

3954 * dbusbind.c (Fdbus_init_bus):
3956 * xterm.c (x_term_init):

3967 no longer needed here.
3968 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:

3970 (set_time_zone_rule): Maintain the TZ=value string separately.
3971 (syms_of_editfns): Don't initialize initial_tz;
3972 init_editfns now does it.

3993 Remove USG and vlimit methods; no longer used these days.
3994 Add #error catchall just in case.
3996 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3997 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,

4023 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
4025 * frame.c (make_frame): Do not set window's buffer to t.
4026 * window.c (Fsplit_window_internal): Likewise. Previously it was
4027 used to indicate that the window is being set up. Now we use
4028 set_window_buffer for all new windows, so the condition in ...
4029 (Fset_window_buffer): ... is always true and can be removed.
4031 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
4033 Convenient macro to check whether the buffer is hidden.
4034 * buffer.h (BUFFER_HIDDEN_P): New macro.

4058 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
4060 Fix a recently-introduced delete-process race condition.
4061 * callproc.c, process.h (record_kill_process):
4062 New function, containing part of the old call_process_kill.
4063 (call_process_kill): Use it.
4064 This does not change call_process_kill's behavior.
4065 * process.c (Fdelete_process): Use record_kill_process to fix a
4066 race condition that could cause Emacs to lose track of a child.
4068 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
4070 Avoid code duplication between prev_frame and next_frame.
4071 * frame.c (candidate_frame): New function. Add comment.

4074 2012-12-06 Eli Zaretskii <eliz@gnu.org>
4076 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
4077 fails, signal an error instead of continuing with an empty
4079 Encode expanded temp file pattern before passing it to mkstemp or
4082 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
4083 Encode the file name before passing it to dostounix_filename, in
4084 case it will downcase it (under w32-downcase-file-names).
4087 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
4089 Minor call-process cleanups.
4090 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
4091 at the same time as other platforms, to simplify analysis.
4092 No need for fd0_volatile since we have synch_process_fd.
4093 Avoid needless emacs_close; arg is always negative.
4095 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
4097 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

4102 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
4103 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
4104 and mouse_face_hidden members to a bitfields.
4105 * frame.h (struct frame): Remove set-but-not-used space_width member.
4106 (FRAME_SPACE_WIDTH): Remove.

4109 member. Adjust users. Convert term_initted, delete_in_insert_mode,
4110 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
4111 members to a bitfields.
4113 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
4115 Don't let call-process be a zombie factory (Bug#12980).
4116 Fixing this bug required some cleanup of the signal-handling code.
4117 As a side effect, this change also fixes a longstanding rare race
4118 condition whereby Emacs could mistakenly kill unrelated processes,
4119 and it fixes a bug where a second C-g does not kill a recalcitrant
4120 synchronous process in GNU/Linux and similar platforms.
4121 The patch should also fix the last vestiges of Bug#9488,
4122 a bug which has mostly been fixed on the trunk by other changes.
4123 * callproc.c, process.h (synch_process_alive, synch_process_death)
4124 (synch_process_termsig, sync_process_retcode):
4125 Remove. All uses removed, to simplify analysis and so that
4126 less consing is done inside critical sections.
4127 * callproc.c (call_process_exited): Remove. All uses replaced
4128 with !synch_process_pid.
4129 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
4130 These take the role of what used to be in unwind-protect arg.
4132 (block_child_signal, unblock_child_signal):
4133 New functions, to avoid races that could kill innocent-victim processes.
4134 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
4135 (call_process_kill): Record killed processes as deleted, so that
4136 zombies do not clutter up the system. Do this inside a critical
4137 section, to avoid a race that would allow the clutter.
4138 (call_process_cleanup): Fix code so that the second C-g works again
4139 on common platforms such as GNU/Linux.
4140 (Fcall_process): Create the child process in a critical section,
4141 to fix a race condition. If creating an asynchronous process,
4142 record it as deleted so that zombies do not clutter up the system.
4143 Do unwind-protect for WINDOWSNT too, as that's simpler in the
4144 light of these changes. Omit unnecessary call to emacs_close
4145 before failure, as the unwind-protect code does that.
4146 * callproc.c (call_process_cleanup):
4147 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
4148 * process.c (record_deleted_pid): New function, containing
4149 code refactored out of Fdelete_process.
4150 (Fdelete_process): Use it.
4151 (process_status_retrieved): Remove. All callers changed to use
4152 child_status_change.
4153 (record_child_status_change): Remove, folding its contents into ...
4154 (handle_child_signal): ... this signal handler. Now, this
4155 function is purely a handler for SIGCHLD, and is not called after
4156 a synchronous waitpid returns; the synchronous code is moved to
4157 wait_for_termination. There is no need to worry about reaping
4158 more than one child now.
4159 * sysdep.c (get_child_status, child_status_changed): New functions.
4160 (wait_for_termination): Now takes int * status and bool
4161 interruptible arguments, too. Do not record child status change;
4162 that's now the caller's responsibility. All callers changed.
4163 Reimplement in terms of get_child_status.
4164 (wait_for_termination_1, interruptible_wait_for_termination):
4165 Remove. All callers changed to use wait_for_termination.
4166 * syswait.h: Include <stdbool.h>, for bool.
4167 (record_child_status_change, interruptible_wait_for_termination):
4169 (record_deleted_pid, child_status_changed): New decls.
4170 (wait_for_termination): Adjust to API changes noted above.
4172 * bytecode.c, lisp.h (Qbytecode): Remove.

4229 Fix xpalloc confusion after memory is exhausted.
4230 * alloc.c (xpalloc): Comment fix.
4231 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory

4276 * callproc.c (Fcall_process): Fix vfork portability problems.
4277 Do not assume that fd[0], count, filefd, and save_environ survive
4278 vfork. Fix bug whereby wrong errno value could be reported for
4279 pipe failure. Some minor cleanups, too, as follows. Move buf and
4280 bufsize to the context where they're needed. Change new_argv to
4281 be of type char **, as this is more convenient and avoids casts.
4282 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4283 Now local constants, not macros.
4285 2012-11-18 Kenichi Handa <handa@gnu.org>

4335 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4336 between bpos_covered and bpos_max. This fixes cursor display when
4337 several display strings follow each other.
4339 * .gdbinit (pgx): If the glyph's object is a string, display the
4340 pointer to string data, rather than the value of the string object
4341 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4343 * indent.c (Fvertical_motion): If the starting position is covered
4344 by a display string, return to one position before that, to avoid
4345 overshooting it inside move_it_to. (Bug#12930)
4347 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

4359 * xterm.h (struct x_output): Drop outdated #if 0 code.
4360 Use bitfields for explicit_parent, asked_for_visible,
4361 has_been_visible and net_wm_state_hidden_seen members.

4373 (NAMLEN): Remove, replacing with ...
4374 (dirent_namelen): New function. All uses changed. Use the GNU macro
4375 _D_EXACT_NAMELEN if available, as it's faster than strlen.

4388 * xftfont.c (xftfont_open): Remove duplicate assignment.
4390 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4392 * alloc.c (Fgarbage_collect): Unblock input after clearing

4394 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4395 * msdos.c (IT_frame_up_to_date): Use it here...
4396 * w32term.c (w32_frame_up_to_date): ...here...
4397 * xterm.c (XTframe_up_to_date): ...and here...
4398 * nsterm.m (ns_frame_up_to_date): ...but not here.

4440 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4442 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4443 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4444 Define for the MSVC compiler.
4446 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

4491 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4492 cygwin_convert_file_name*.
4494 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):

4501 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4503 * w32select.c: Include w32common.h before w32term.h, so that
4504 windows.h gets included before w32term.h uses some of its
4505 features, see below.

4509 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

4537 * emacs.c, term.c (O_RDWR): Remove.
4538 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than

4541 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4542 (create_pty, Fmake_network_process, server_accept_connection)
4543 (wait_reading_process_output, init_process_emacs):
4545 (wait_reading_process_output): Put in a special case for WINDOWSNT
4546 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4547 It's not clear this is needed, but it's a more-conservative change.
4548 (create_process): Assume FD_CLOEXEC.
4549 (create_process, create_pty): Assume O_NOCTTY.
4550 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4551 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4552 Omit if not DOS_NT, since F_GETFL is not defined there.
4553 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4554 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4556 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4557 lack it, since gnulib guarantees this.

4560 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4562 * w32.c (faccessat): Pretend that directories have the execute bit
4563 set. Emacs expects that, e.g., in files.el:cd-absolute.
4565 * w32proc.c (create_child): Don't clip the PID of the child
4566 process to fit into an Emacs integer, as this is no longer a
4568 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4569 reaping only the process specified by PID argument, if that is
4570 positive. Use PID instead of dead_child to know which process to
4571 reap. Wait for the child to die only if WNOHANG is not in
4573 (sys_select): Don't set dead_child.
4575 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4576 as it is no longer needed.
4578 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,

4585 Fix problems in ns port found by static checking.
4586 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4587 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4588 not to process group.
4589 (ns_select): Use emacs_write, not write, as that's more robust
4590 in the presence of signals.
4591 (fd_handler:): Check for read errors.
4593 2012-11-16 Glenn Morris <rgm@gnu.org>
4595 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

4603 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4604 use the same value of thread handle.
4605 (start_timer_thread): If the timer thread exited (due to error),
4606 clean up by closing the two handles it used. Duplicate the caller
4607 thread's handle here, so it gets duplicated only once, when
4608 launching the timer thread. Set priority of the timer thread, not
4610 (getitimer): Don't duplicate the caller thread's handle here.
4613 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4615 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4618 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4620 Remove no-longer-used pty_max_bytes variable.
4621 * process.c (pty_max_bytes): Remove; unused.
4622 (send_process): Do not set it.
4624 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4626 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4627 Update dependencies.
4629 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4631 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4632 This follows up on the 2012-09-29 patch that removed indirection
4633 for the 'function' field. Reported by Sergey Vinokurov in
4634 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4636 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4638 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4639 different name, as the MS runtime does not have such a function,
4640 and probably never will.) All callers changed. Ignore DIRFD
4641 value if PATH is an absolute file name, to match Posix spec
4642 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4645 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4647 * xdisp.c (echo_area_display, redisplay_internal):
4648 Omit redundant check whether frame_garbaged is set.
4650 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4652 Use faccessat, not access, when checking file permissions (Bug#12632).
4653 This fixes a bug that has been present in Emacs since its creation.
4654 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4655 which must set some sort of record. (Torek's bug report was against
4656 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4657 same common flaw.) See Torek's Usenet posting
4658 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4659 Posted: Fri Apr 8 14:18:56 1983.
4660 * Makefile.in (LIB_EACCESS): New macro.
4662 * callproc.c (init_callproc):
4663 * charset.c (init_charset):
4664 * fileio.c (check_existing, check_executable, check_writable)
4666 * lread.c (openp, load_path_check):
4667 * process.c (allocate_pty):
4669 Use effective UID when checking permissions, not real UID.
4670 * callproc.c (init_callproc):
4671 * charset.c (init_charset):
4672 * lread.c (load_path_check, init_lread):
4673 Test whether directories are accessible, not merely whether they exist.
4674 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4675 * fileio.c (check_existing, check_executable, check_writable)
4677 Use symbolic names instead of integers for the flags, as they're
4679 (check_writable): New arg AMODE. All uses changed.
4680 Set errno on failure.
4681 (Ffile_readable_p): Use faccessat, not stat + open + close.
4682 (Ffile_writable_p): No need to call check_existing + check_writable.
4683 Just call check_writable and then look at errno. This saves a syscall.
4684 dir should never be nil; replace an unnecessary runtime check
4685 with an eassert. When checking the parent directory of a nonexistent
4686 file, check that the directory is searchable as well as writable, as
4687 we can't create files in unsearchable directories.
4688 (file_directory_p): New function, which uses 'stat' on most platforms
4689 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4690 (Ffile_directory_p, Fset_file_times): Use it.
4691 (file_accessible_directory_p): New function, which uses a single
4692 syscall for efficiency.
4693 (Ffile_accessible_directory_p): Use it.
4694 * xrdb.c (file_p): Use file_directory_p.
4695 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4696 * lread.c (openp): When opening a file, use fstat rather than
4697 stat, as that avoids a permissions race. When not opening a file,
4698 use file_directory_p rather than stat.
4699 (dir_warning): First arg is now a usage string, not a format.
4700 Use errno. All uses changed.
4701 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4702 that merely introduced a race.
4703 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4704 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4705 and similarly for the other O_* flags.
4706 * w32.c (sys_faccessat): Rename from sys_access and switch to
4707 faccessat's API. All uses changed.
4708 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4709 (magic_db): Rename from magic_file_p.
4710 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4711 char *, so that we don't have to test for file existence
4712 separately from opening the file for reading. This removes a race
4713 fixes a permission-checking problem, and simplifies the code.
4715 (file_p): Remove; no longer needed.
4717 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4719 Omit glyphs initialization at startup.
4720 * dispnew.c (glyphs_initialized_initially_p): Remove.
4721 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4722 (Fredraw_frame): Move actual code from here...
4723 (redraw_frame): ...to here. Add eassert. Adjust comment.
4724 (Fredraw_display): Use redraw_frame.
4725 * xdisp.c (clear_garbaged_frames): Likewise.
4727 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4729 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4730 passed to pint2str and pint2hrstr to be at most the size of the
4731 frame's decode_mode_spec_buffer. This avoids crashes with very
4732 large values of FIELD_WIDTH argument to decode_mode_spec.
4735 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4737 Fix a race with verify-visited-file-modtime (Bug#12863).
4738 Since at least 1991 Emacs has ignored an mtime difference of no
4739 more than one second, but my guess is that this was to work around
4740 file system bugs that were fixed long ago. Since the race is
4741 causing problems now, let's remove that code.
4742 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4743 whose time stamp is off by no more than a second. Insist that the
4744 file time stamps match exactly.
4746 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4748 * frame.h (struct frame): Convert external_tool_bar member to
4749 1-bit unsigned bitfield.
4750 * termhooks.h (struct terminal): Remove mouse_moved member since
4751 all users are long dead. Adjust comment on mouse_position_hook.
4753 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4755 Simplify by using FOR_EACH_FRAME here and there.
4756 * frame.c (next_frame, prev_frame, other_visible_frames)
4757 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4758 * w32term.c (x_window_to_scroll_bar): Likewise.
4759 * window.c (window_list): Likewise.
4760 * xdisp.c (x_consider_frame_title): Likewise.
4761 * xfaces.c (Fdisplay_supports_face_attributes_p): Likewise.
4762 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4763 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4764 * xmenu.c (menubar_id_to_frame): Likewise.
4765 * xselect.c (frame_for_x_selection): Likewise.
4766 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4767 (x_window_to_menu_bar): Likewise.
4768 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4770 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4772 * data.c (Qdefalias_fset_function): Now static.
4774 Another tweak to vectorlike_header change.
4775 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4776 Remove, and replace all uses with ...
4777 (next_in_free_list, set_next_in_free_list):
4778 New functions, which respect C's aliasing rules better.
4780 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4782 * window.c (list4i): Rename from 'quad'. All uses changed.
4783 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4785 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4787 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4788 warning about mixing declarations and code in ISO C90.
4790 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4792 * window.c (Fsplit_window_internal): Set combination limit of
4793 new parent window to t iff Vwindow_combination_limit is t;
4794 fixing a regression introduced with the change from 2012-09-22.
4795 (Fset_window_combination_limit): Fix doc-string.
4797 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4799 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4800 amount when the scroll margins are too large. When scrolling
4801 backwards in the buffer, give up if cannot reach point or the
4802 scroll margin within a reasonable number of screen lines.
4803 Fixes point position in window under scroll-up/down-aggressively when
4804 point is positioned many lines beyond the window top/bottom.
4807 * ralloc.c (relinquish): If real_morecore fails to return memory
4808 to the system, don't crash; instead, leave the last heap
4809 unchanged and return. (Bug#12774)
4811 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4813 * lisp.h (AUTOLOADP): New macro.
4814 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4815 * data.c (Ffset): Remove special ad-advice-info handling.
4816 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4818 (Finteractive_form): Simplify.
4819 (Fquo): Don't insist on having at least 2 arguments.
4820 (Qdefalias_fset_function): New var.
4822 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4824 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4826 * nsfont.m (Qcondensed, Qexpanded): New variables.
4827 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4828 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4830 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4832 Fix recently introduced crash on MS-Windows (Bug#12839).
4833 * w32term.h (struct scroll_bar): Use convenient header.
4834 (SCROLL_BAR_VEC_SIZE): Remove.
4835 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4837 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4839 Tweak last vectorlike_header change.
4840 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4841 vectorlike object on the free list. This is introduced to avoid
4842 some (but not all) pointer casting and aliasing problems, see
4843 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4844 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4846 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4848 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4850 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4851 been removed, so remove them here also.
4853 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4855 * doc.c (Fdocumentation): Handle new property
4856 dynamic-docstring-function to replace the old ad-advice-info.
4858 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4860 * fns.c (Qeql, hashtest_eq): Now static.
4862 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4864 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4865 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4866 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4867 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4869 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4871 Use same hash function for hashfn_profiler as for hash_string etc.
4872 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4873 * lisp.h (sxhash_combine): New inline function, with the contents
4874 of the old SXHASH_COMBINE.
4875 * profiler.c (hashfn_profiler): Use it, instead of having a
4876 special hash function containing a comparison that always yields 1.
4878 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4880 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4881 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4882 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4885 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4887 * image.c (xpm_make_color_table_h): Fix compiler error because
4888 make_hash_table changed.
4890 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4892 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4894 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4896 Use ad-hoc comparison function for the profiler's hash-tables.
4897 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4898 (make_log): Use them.
4899 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4900 call Fequal any more.

4909 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4910 (hash_lookup, hash_remove_from_table): Move assertion checking of
4911 hashfn result here. Check hash-equality before calling cmpfn.

4921 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4923 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4924 value of w32-scroll-lock-modifier is neither nil nor one of the
4925 known key modifiers. (Bug#12806)
4927 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4929 Shrink struct vectorlike_header to the only size field.
4930 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4932 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4933 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4934 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4935 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4936 information from the vector header. Adjust comment.

4948 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4949 (Fmake_bool_vector): Likewise.
4950 (struct large_vector): New type to represent allocation unit for
4951 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4952 (large_vectors): Change type to struct large_vector.
4953 (allocate_vector_from_block): Simplify.
4954 (PSEUDOVECTOR_NBYTES): Replace with...
4955 (vector_nbytes): ...new function. Adjust users.
4956 (sweep_vectors): Adjust processing of large vectors.
4957 (allocate_vectorlike): Likewise.

4961 (live_vector_p): Adjust to match large vector.
4962 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4963 * buffer.h (struct buffer): Add next member.
4964 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):

4972 (xvecsize): New command.
4974 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4976 * keyboard.c (event_to_kboard): Do not dereference
4977 frame_or_window field of SELECTION_REQUEST_EVENT
4978 and SELECTION_CLEAR_EVENT events (Bug#12814).
4979 * xterm.h (struct selection_input_event): Adjust comment.
4981 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4983 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4984 such as Scroll Lock, if the respective keys are treated as
4985 function keys, not as modifiers. This avoids destroying non-ASCII
4986 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4988 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4990 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4992 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4994 Restore some duplicate definitions (Bug#12814).
4995 This undoes part of the 2012-11-03 changes. Some people build
4996 with plain -g rather than with -g3, and they need the duplicate
4997 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4998 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4999 Define as macros, as well as as enums or as constants.
5001 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
5003 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
5004 to keypad keys (Bug#12816).
5006 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
5008 Minor adjustments of recently-changed frame functions.
5009 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
5010 known to be a frame (we're in the FRAMEP branch).
5011 * lisp.h (Qframep): Remove decl. frame.h declares this.
5012 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
5013 since they're meant for Lisp fixnum values.
5015 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
5017 * window.c (Fwindow_combination_limit): Revert to the only
5018 required argument and adjust docstring as suggested in
5019 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
5020 by Martin Rudalics <rudalics@gmx.at>.

5071 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
5073 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
5074 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
5075 file descriptor 2 for standard error. (Bug#12805)
5077 2012-11-05 Chong Yidong <cyd@gnu.org>
5079 * process.c (wait_reading_process_output): Revert previous change.
5081 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
5083 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
5084 This removes code that has been obsolete since around 1990.
5085 * callproc.c (Fcall_process):
5087 * process.c (create_process):
5088 * term.c (dissociate_if_controlling_tty):
5089 Assume setsid exists.
5090 * callproc.c (child_setup): Assume setpgid exists and behaves as
5091 per POSIX.1-1988 or later.
5092 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
5093 * emacs.c (shut_down_emacs):
5094 * sysdep.c (sys_suspend, init_foreground_group):
5095 Assume getpgrp behaves as per POSIX.1-1998 or later.
5096 * msdos.c (setpgrp): Remove.
5097 (tcgetpgrp, setpgid, setsid): New functions.
5098 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
5099 * term.c (no_controlling_tty): Remove; unused.
5100 * w32proc.c (setpgrp): Remove.
5101 (setsid, tcgetpgrp): New functions.
5103 Simplify by assuming __fpending.
5104 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
5105 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
5106 Do not assume that __fpending's result fits in int.
5108 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
5110 Remove EMACS_OUTQSIZE+sleep hack.
5111 * dispnew.c (update_frame_1): Remove hack for terminals slower
5112 than 2400 bps, which throttled Emacs by having it sleep.
5113 This code hasn't worked since at least 2007, when the multi-tty stuff
5114 was added, and anyway those old terminals are long dead.
5115 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
5116 without the dispnew.c change, as dispnew.c doesn't include systty.h.
5118 Fix data-loss with --version (Bug#9574).
5119 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
5120 as we can't assume that emacs_strerror is initialized, and strerror
5121 is good enough here.
5122 (main): Invoke atexit earlier, to catch earlier instances of
5123 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
5125 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
5127 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
5128 (keyDown): Remap keypad keys to X11 virtual key codes.
5130 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
5132 Fix data-loss with --batch (Bug#9574).
5133 * emacs.c: Include <close-stream.h>.
5134 (close_output_streams): New function.
5135 (main): Pass it to atexit, so that Emacs closes stdout and stderr
5136 and handles errors appropriately.
5137 (Fkill_emacs): Don't worry about flushing, as close_output_stream
5140 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
5141 The symptom is a diagnostic "GLib-WARNING **: In call to
5142 g_spawn_sync(), exit status of a child process was requested but
5143 SIGCHLD action was set to SIG_IGN and ECHILD was received by
5144 waitpid(), so exit status can't be returned." The diagnostic
5145 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
5146 The real bug is a race condition between Emacs and glib: Emacs
5147 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
5148 so that glib can't find it. Work around the bug by invoking
5149 waitpid only on subprocesses that Emacs itself creates.
5150 * process.c (create_process, record_child_status_change):
5151 Don't use special value -1 in pid field, as the caller now must
5152 know the pid rather than having the callee infer it.
5153 The inference was sometimes incorrect anyway, due to another race.
5154 (create_process): Set new 'alive' member if child is created.
5155 (process_status_retrieved): New function.
5156 (record_child_status_change): Use it.
5157 Accept negative 1st argument, which means to wait for the
5158 processes that Emacs already knows about. Move special-case code
5159 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
5160 processes that have already been waited for, by testing and
5161 clearing new 'alive' member.
5162 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
5163 now does this internally.
5164 (handle_child_signal): Let record_child_status_change do all
5165 the work, since we do not want to reap all exited child processes,
5166 only the child processes that Emacs itself created.
5167 * process.h (Lisp_Process): New boolean member 'alive'.
5169 Omit duplicate definitions no longer needed with gcc -g3.
5170 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
5171 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
5172 Define only as macros. There's no longer any need to also define
5173 these symbols as enums or as constants, since we now assume
5174 gcc -g3 when debugging.
5176 2012-11-03 Eli Zaretskii <eliz@gnu.org>
5178 * lisp.mk: Adjust comments to the fact that term/internal is now
5179 loaded from loadup.el.
5181 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5182 (msdos_fatal_signal): New function.
5183 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5186 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5187 for GCC versions before 4.
5188 (emacs_raise): Define to call msdos_fatal_signal.
5190 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5191 iterator when starting in the middle of a display or overlay
5194 2012-11-03 Chong Yidong <cyd@gnu.org>
5196 * process.c (wait_reading_process_output): Clean up the last
5199 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5201 * process.c (wait_reading_process_output): Avoid a race condition
5202 with SIGIO delivery (Bug#11536).
5204 2012-11-03 Chong Yidong <cyd@gnu.org>
5206 * buffer.c (cursor_type): Untabify docstring.
5208 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5210 * frame.h (struct frame): Drop can_have_scroll_bars member
5211 which is meaningless for a long time. Adjust comments.
5212 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
5213 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
5215 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5217 * window.c (decode_next_window_args): Update window arg after
5218 calling decode_live_window and so fix crash reported at
5219 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
5220 by Juanma Barranquero <lekktu@gmail.com>.
5221 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
5222 * font.c (Ffont_at): Likewise.
5224 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
5226 * widget.c (resize_cb): New function.
5227 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
5228 (EmacsFrameResize): Check if all is up to date before changing frame
5231 2012-11-02 Eli Zaretskii <eliz@gnu.org>
5233 Implement backtrace output for fatal errors on MS-Windows.
5234 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
5235 (BACKTRACE_LIMIT_MAX): New macro.
5236 (w32_backtrace): New function.
5237 (emacs_abort): Use w32_backtrace when the user chooses not to
5238 attach a debugger. Update the text of the abort dialog.
5240 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5242 Window-related stuff cleanup here and there.
5243 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
5244 Use decode_any_window.
5245 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
5246 * xdisp.c (Fformat_mode_line): Likewise.
5247 * font.c (Ffont_at): Use decode_live_window.
5248 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
5249 * window.c (decode_next_window_args): Likewise.
5250 (decode_any_window): Remove static.
5251 * window.h (decode_any_window): Add prototype.
5252 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
5253 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
5256 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5258 Remove pad from struct input_event.
5259 * termhooks.h (struct input_event): Remove padding field.
5261 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5262 member is never cons for a long time. Adjust comment.
5263 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5264 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5265 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5266 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5268 2012-11-01 Eli Zaretskii <eliz@gnu.org>
5270 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
5272 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5274 Fix crash when using Emacs as commit editor for git (Bug#12697).
5275 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5276 and it is configured in conf_post.h.
5277 (Fcall_process): Don't invoke both setsid and setpgid; the former
5278 is enough, if it exists.
5279 * callproc.c (Fcall_process, child_setup):
5280 * process.c (create_process): Use setpgid.
5281 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5283 * dispnew.c (init_display): Initialize the foreground group
5284 if we are running a tty display.
5285 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
5286 * lisp.h (init_foreground_group): New decl.
5287 * sysdep.c (inherited_pgroup): New static var.
5288 (init_foreground_group, tcsetpgrp_without_stopping)
5289 (narrow_foreground_group, widen_foreground_group): New functions.
5290 (init_sys_modes): Narrow foreground group.
5291 (reset_sys_modes): Widen foreground group.
5293 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
5295 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
5297 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5299 * minibuf.c (read_minibuf): Restore current buffer since
5300 choose_minibuf_frame calling Fset_frame_selected_window may
5301 change it (Bug#12766).
5303 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
5305 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
5307 2012-10-30 Kenichi Handa <handa@gnu.org>
5309 * font.c (Ffont_at): If WINDOW is specified and it is not
5310 displaying the current buffer, signal an error.
5312 2012-10-29 Daniel Colascione <dancol@dancol.org>
5314 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5315 In preparation for fixing bug#12739, move these functions from
5318 * coding.h, coding.c: ... to here, and compile them only when
5319 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5320 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5322 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5324 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5325 (timer_loop, getitimer, setitimer): Use it instead of
5326 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
5328 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
5331 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
5333 * nsterm.m (NO_APPDEFINED_DATA): New define.
5334 (last_appdefined_event_data): New variable
5335 (last_appdefined_event): Remove.
5336 (ns_select): Initialize t from last_appdefined_event_data instead
5337 of [last_appdefined_event data1].
5338 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
5339 remove last_appdefined_event (Bug#12698).
5341 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5343 * frame.c (x_set_font): Catch internal error.
5345 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5347 Avoid overflow in w32 implementation of interval timers.
5348 When possible, for ITIMER_PROF count only times the main thread
5350 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5351 'volatile ULONGLONG' types. All the other data which was
5352 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5353 (GetThreadTimes_Proc): New typedef.
5354 (w32_get_timer_time): New function, returns a suitable time value
5356 (timer_loop): Enter critical section when accessing ULONGLONG
5357 values of the itimer_data struct, as these accesses are no longer
5358 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5359 Remove unused variable.
5360 (init_timers): Initialize s_pfn_Get_Thread_Times.
5361 (start_timer_thread): Don't assign itimer->caller_thread here.
5362 (getitimer): Assign itimer->caller_thread here.
5363 (setitimer): Always call getitimer to get the value of ticks_now.
5364 (sys_spawnve): Avoid compiler warning about format mismatch.
5366 2012-10-26 Eli Zaretskii <eliz@gnu.org>
5368 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5369 mouse movement events if the menu bar is active. This avoids
5370 producing a busy "hour-glass" cursor by Windows if the mouse
5371 pointer is positioned over a tooltip shown for some menu item.
5373 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5375 Don't assume process IDs fit in int.
5376 * emacs.c (shut_down_emacs) [!DOS_NT]:
5377 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5378 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5379 Use pid_t, not int, to store process IDs, as 'int'
5380 is not wide enough on a few platforms (e.g., AIX and IRIX).
5382 2012-10-23 Kenichi Handa <handa@gnu.org>
5384 The following change is to make face-font-rescale-alist work
5385 correctly for non-ASCII fonts.
5387 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
5388 (font_open_for_lface): Handle Vface_font_rescale_alist.
5390 2012-10-23 Chong Yidong <cyd@gnu.org>
5392 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
5394 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
5396 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
5398 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
5400 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
5403 2012-10-21 Glenn Morris <rgm@gnu.org>
5405 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5407 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5409 Port to OpenBSD 5.1.
5410 * frame.c (Fmouse_position, Fmouse_pixel_position):
5411 * xdisp.c (produce_stretch_glyph):
5412 Declare local vars only when they're needed.
5413 This is clearer and avoids a warning on OpenBSD about unused vars.
5414 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
5415 This is safer, and avoids OpenBSD warnings about unused vars.
5416 * keyboard.c (record_menu_key): Remove unnecessary decl.
5417 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5418 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5419 as our definition clashes with OpenBSD's.
5420 * xfaces.c (load_face_colors, check_lface_attrs)
5421 (get_lface_attributes_no_remap, get_lface_attributes)
5422 (lface_fully_specified_p, x_supports_face_attributes_p)
5423 (tty_supports_face_attributes_p, face_fontset, realize_face)
5424 (realize_x_face, realize_tty_face):
5425 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5426 merely Lisp_Object *. This is more informative and avoids
5427 a warning on OpenBSD about accessing beyond an object's size.
5429 2012-10-20 Chong Yidong <cyd@gnu.org>
5431 * lread.c (Fload): Doc fix (Bug#12592).
5433 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
5435 * font.c (Ffont_at): Fix previous change.
5437 2012-10-19 Eli Zaretskii <eliz@gnu.org>
5439 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
5440 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
5443 * alloc.c (NSTATICS): Decrease to 0x800.
5445 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
5447 * fns.c (Fnreverse): Include the problem element when signaling an
5450 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
5452 * nsterm.m (ns_select): Check writefds before call to
5453 FD_ISSET (Bug#12668).
5455 2012-10-18 Daniel Colascione <dancol@dancol.org>
5457 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5458 (staticpro): If we run out of staticpro slots, die with an
5459 informative error instead of just calling emacs_abort.
5461 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5463 Fix two flaws reported by Dmitry Antipov.
5464 * window.c (Ftemp_output_buffer_show): Remove.
5465 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
5466 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
5468 2012-10-17 Eli Zaretskii <eliz@gnu.org>
5470 * makefile.w32-in ($(BLD)/w32.$(O)):
5471 ($(BLD)/vm-limit.$(O)):
5473 ($(BLD)/unexw32.$(O)):
5474 ($(BLD)/fileio.$(O)):
5475 ($(BLD)/dispnew.$(O)): Update dependencies.
5477 * w32term.h (w32_initialize_display_info, initialize_w32_display):
5480 * w32proc.c: Include ctype.h.
5482 * w32.h (init_environment, check_windows_init_file)
5483 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
5484 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
5485 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
5486 (sys_link): Add prototypes.
5488 * w32.c: Include w32select.h.
5489 (sys_access, e_malloc, sys_select): Add prototypes.
5490 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
5492 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
5494 * unexw32.c: Include lisp.h and w32.h.
5496 * term.c [WINDOWSNT]: Include w32term.h.
5498 * process.c [WINDOWSNT]: Add prototype of sys_select.
5500 * fileio.c [WINDOWSNT]: Include w32.h.
5502 * dispnew.c [WINDOWSNT]: Include w32.h.
5504 * cygw32.c (Fcygwin_convert_path_to_windows)
5505 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
5506 Lisp_Object values. (Bug#12661)
5508 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
5509 to Lisp_Object. (Bug#12661)
5511 2012-10-17 Kenichi Handa <handa@gnu.org>
5513 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
5516 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
5518 * buffer.c (Fkill_buffer): When unchaining the marker,
5519 reset its buffer pointer to NULL (Bug#12652).
5521 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
5523 Do not verify indirection counters of killed buffers (Bug#12579).
5524 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
5525 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
5527 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
5529 * alloc.c (Fmake_byte_code): Fix typo in comment.
5530 * print.c (print_interval): Define as static to match prototype.
5531 * indent.c (disptab_matches_widthtab, recompute_width_table):
5534 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
5536 * editfns.c (get_system_name): Remove.
5537 * lisp.h (get_system_name): Remove prototype.
5538 * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes.

5556 headers define to something incompatible.
5558 2012-10-14 Daniel Colascione <dancol@dancol.org>
5560 * image.c (init_tiff_functions, init_imagemagick_functions)
5561 (init_svg_functions): Fix cygw32 build break by using these
5562 functions only when WINDOWSNT _and_ HAVE_NTGUI.

5583 Fix some stat-related races.
5584 * fileio.c (Fwrite_region): Avoid race condition if a file is
5585 removed or renamed by some other process immediately after Emacs
5586 writes it but before Emacs stats it. Do not assume that stat (or
5588 * image.c (slurp_file): Resolve the file name with fopen + fstat
5589 rather than stat + fopen.

5607 is zero (Bug#12384).
5609 2012-10-12 Juanma Barranquero <lekktu@gmail.com>

5615 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
5617 * fileio.c (check_existing): New function.
5618 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
5619 instead of calling 'stat', when what's needed is to check whether
5620 a file exists. This avoids expensive system calls on MS-Windows.
5623 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
5625 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

5630 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
5632 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

5674 * marker.c (cached_modiff): EMACS_INT, not int.
5676 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
5677 instead of having a wrong decl.

5715 (detect_input_pending_run_timers):
5716 * process.c (wait_reading_process_output):
5717 Use unsigned for counter where wraparound-on-overflow is desired,
5718 since unsigned is guaranteed to have that behavior and signed is not.
5719 (read_char): Use ptrdiff_t for string length.
5720 (get_input_pending): Remove first argument, since it was always
5721 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5722 and behave as if it had that value. Return new value of
5723 input_pending. All callers changed.
5724 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5725 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5727 * keymap.c (push_key_description): Omit last arg, which was always 1.
5728 All callers changed.
5730 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
5732 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

5748 Don't include termopts.h.
5750 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5752 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5754 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5756 * commands.h (immediate_quit): Remove duplicate decl.
5758 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5760 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

5763 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5765 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5767 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5768 match what GetLastError returns. Explain why the function is
5771 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5772 'is_tooltip_frame', to avoid confusion with its global namesake.
5774 2012-10-08 Daniel Colascione <dancol@dancol.org>
5776 * xdisp.c (start_hourglass): Call w32_note_current_window when
5777 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5778 build that caused Emacs to display the hourglass cursor forever.
5780 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5781 which is broken under remote desktop, calculate the number of
5782 colors available for a display based on the display's number of
5783 planes and number of bits per pixel per plane. (bug#10397).
5785 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5787 * nsfont.m (Vfonts_in_cache): New variable.
5788 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5789 are used. Add cached fonts to Vfonts_in_cache.
5790 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5792 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5794 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5796 (FONT_H): Define after FRAME_H.
5797 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5798 Update dependencies.
5800 * w32term.c: Remove leftover declaration of keyboard_codepage.
5802 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5804 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5805 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5806 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5807 (GLOBAL_SOURCES): Add cygw32.c.
5808 ($(BLD)/unexw32.$(O)):
5810 ($(BLD)/w32console.$(O)):
5811 ($(BLD)/w32fns.$(O)):
5812 ($(BLD)/w32heap.$(O)):
5813 ($(BLD)/w32menu.$(O)):
5814 ($(BLD)/w32proc.$(O)): Add w32common.h.
5816 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5818 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5820 2012-10-08 Daniel Colascione <dancol@dancol.org>
5822 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5823 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5824 accidental message numbering hole. Change other messages to
5827 * w32select.h (HAVE_W32SELECT): Remove.
5829 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5830 w32common.h instead of w32heap.h.
5832 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5833 (get_allocation_unit, get_processor_type, get_w32_major_version)
5834 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5835 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5836 (OS_NT, os_subtype, cache_system_info): Move declarations to

5840 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5841 (w32_minor_version, w32_build_number, w32_subtype):
5842 Remove duplicate definitions.
5844 * w32fns.c: Include w32common.h; include w32heap.h only in
5847 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5848 Use `report_file_error' instead of `error' in order to better
5849 inform users of what went wrong. Increase NTGUI_UNICODE file
5850 dialog box file name length to 32k, the maximum allowed by the NT
5853 * w32common.h: New file.
5854 (ROUND_UP, ROUND_DOWN, get_page_size)
5855 (get_allocation_unit, get_processor_type, get_w32_major_version)
5856 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5857 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5858 (OS_NT, os_subtype, cache_system_info): Move here.
5860 * unexw32.c, unexcw.c: Include w32common.h.
5862 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5863 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5864 to call syms_of_w32select.
5866 * cygw32.h: Remove obsolete EXFUN declarations.
5868 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

5871 of w32inevt.o from SOME_MACHINE_OBJECTS.
5873 2012-10-08 Daniel Colascione <dancol@dancol.org>
5875 * image.c: Permanent fix for JPEG compilation issue --- limit
5876 jpeglib `boolean' redefinition to Cygwin builds.
5878 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5880 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5882 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5885 2012-10-08 Daniel Colascione <dancol@dancol.org>
5887 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5888 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5889 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5890 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5891 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5892 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5893 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5894 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5895 now a supported configuration.
5897 * Makefile.in: consolidate image variables into LIBIMAGE; add
5898 W32_OBJ and W32_LIBS. Compile new files.
5901 (_DebPrint) declare tracing facility for W32 debugging. We need
5902 to unify tracing later.
5904 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5905 unconditional use of W32 Unicode functions. Cygwin runs only on
5906 100% Unicode operating systems.
5908 * cygw32.c: New file. Define Cygwin-specific facilities.
5909 (Fcygwin_convert_path_to_windows)
5910 (Fcygwin_convert_path_from_windows): New user functions for
5911 accessing Cygwin path-munging routines.
5913 * cygw32.h: New file.
5914 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5915 UTF-16LE strings temporarily inside non-Lisp-visible string
5918 (w32_strerror): Just what it says on the tin.
5920 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5921 also run for Cygwin; both systems have the same problem with using
5922 GUI facilities in a forked child. Also call syms_of_cygw32,
5923 syms_of_w32select in correct places.
5925 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5926 needs fork-then-exec for daemon launching.
5928 * font.h: Include frame.h.
5930 * image.c: Use the image library cache machinery only when we're
5931 compiling for native WINDOWSNT; Cygwin can use shared libraries
5932 like any other Unixlike system.
5934 * keyboard.c: Clarify a comment regarding the input loop.
5936 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5937 functions directly instead of trying to detect at runtime that our
5938 host operating system supports them. We make this change for two
5939 reasons: Cygwin lacks support for the multibyte character
5940 conversion functions used by the legacy menu code, and Cygwin
5941 never needs to rely on non-Unicode APIs.
5943 * unexw32.c (hinst): Declare extern.
5945 * w32.c: Change header order;
5946 (w32_strerror): Move to w32fns.c because we need it for
5947 non-WINDOWSNT builds.
5949 * w32.h: Add #error macro to make sure we don't include w32.h for
5950 Cygwin builds. Remove w32select declarations.
5952 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5953 w32fns.c. w32console.c is WINDOWSNT-only.
5955 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5956 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5958 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5959 (w32_major_version, w32_minor_version, w32_build_number)
5960 (os_subtype, sound_type): Define here
5961 (w32_defined_color): Make color parameter const for consistency
5962 with other _defined_color functions.
5963 (w32_createwindow): Unconditionally call w32_init_class instead of
5964 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5965 through the code is complex and unnecessary because class
5966 registration is practically free.
5967 (w32_name_of_message): New EMACSDEBUG-only function.
5968 (Fset_message_beep): Move here
5969 (Fx_open_connection): Require that the display name for Windows be
5970 "w32" for consistency, emacsclient disambiguation, and maybe, one
5971 day, multi-window-system support.
5972 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5973 Cygwin files for W32 GUI facilities, since these clearly don't
5974 expect Cygwin names.
5975 (_DebPrint): Define.
5976 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5977 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5978 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5979 (w32_last_error): Remove.
5981 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5983 * w32heap.c (syspage_mask): Declare here.
5984 (cache_system_info): Remove.
5986 * w32inevt.c (faked_key): Define globally, not statically.
5987 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5988 (w32_console_toggle_lock_key): Move to w32fns.c.
5990 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5992 * w32proc.c (_DebPrint): Move to w32fns.c.
5993 * w32select.c: Include string.h, stdio.h for Cygwin.
5994 * w32select.h: New File.
5996 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5998 (w32_message_fd): New variable. Under Cygwin, holds the file
5999 descriptor the system used to tell us about pending thread
6002 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
6003 that prevented compilation under non-WINDOWSNT systems.
6005 (w32_initialize): Open /dev/windows and assign it to
6006 w32_message_fd. Provide w32 feature.
6008 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
6009 (WM_EMACS_INPUT_READY): add.
6010 (prepend_msg, w32_message_fd): Declare globally.
6013 (keyboard_handle): Use only when WINDOWSNT.
6014 (notify_msg_ready): New function. Posts a message to the main
6015 thread's message queue under CYGWIN, which wakes up the main
6016 thread from select(2) by making the /dev/windows file descriptor
6017 ready. Under WINDOWSNT, it sets an event the same way the old
6020 (post, prepend_msg): Actually call notify_msg_ready instead of
6021 setting the input event directly.
6023 2012-10-07 Eli Zaretskii <eliz@gnu.org>
6025 * ralloc.c (relinquish): If a heap is ready to be relinquished,
6026 but it still has blocs in it, don't return it to the system,
6027 instead of aborting. (Bug#12402)
6029 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
6031 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

6062 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
6064 Improve sys_siglist detection.
6065 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
6066 defined as a macro, as is done in Solaris.
6067 (sys_siglist_entries): New macro.
6068 (save_strsignal): Use it.
6069 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
6070 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
6072 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
6074 * nsfns.m (Fx_create_frame): Call x_default_parameter with
6075 fullscreen/Fullscreen.
6077 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
6078 tobar_height is new.
6080 * nsterm.m (x_make_frame_visible): Check for fullscreen.
6081 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
6082 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

6091 (canBecomeMainWindow): New function.
6093 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
6095 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
6097 2012-10-05 Eli Zaretskii <eliz@gnu.org>
6099 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
6101 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
6102 that time stamps of directories could also be changed.
6103 Don't request the too broad GENERIC_WRITE, only the more restrictive
6104 FILE_WRITE_ATTRIBUTES access rights.
6106 * fileio.c (Fset_file_times): Special-case ignoring errors for
6107 directories only on MSDOS, not on MS-Windows.
6109 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
6111 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
6113 2012-10-04 Eli Zaretskii <eliz@gnu.org>
6115 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
6116 see whether CreateFile failed.
6118 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
6120 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
6121 to avoid similar races.
6122 * keyboard.c (pending_signals): Now bool, not int.
6124 Port timers to OpenBSD, plus check for timer failures.
6125 OpenBSD problem reported by Han Boetes.
6126 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
6128 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
6129 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
6130 like OpenBSD, which has timer_settime but does not declare it.
6131 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
6132 whether to use itimerspec-related primitives. All uses of
6133 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
6135 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6137 * profiler.c (handle_profiler_signal): Fix a malloc race
6138 that caused Emacs to hang on Fedora 17 when profiling Lisp.
6140 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
6142 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
6144 2012-10-02 Eli Zaretskii <eliz@gnu.org>
6146 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
6147 consistent with the change in return value of 'safe_strsignal'.
6149 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6151 Prefer plain 'static' to 'static inline' (Bug#12541).
6152 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
6153 (bidi_set_sor_type, bidi_push_embedding_level)
6154 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

6159 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6160 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
6161 Now 'static', not 'static inline'.
6163 Count overruns when profiling; change units to ns.
6164 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
6165 Give extra weight to samples after overruns, to attempt to count
6166 the time more accurately.
6167 (setup_cpu_timer): Change sampling interval units from ms to ns, since
6168 the underlying primitives nominally do ns.
6169 (Fprofiler_cpu_start): Document the change. Mention that
6170 the sampling intervals are only approximate.
6172 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6174 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
6176 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
6177 case for the special 0 coding-system.
6179 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
6180 (Fmake_overlay): Remove redundant tests.
6181 (fix_start_end_in_overlays): Remove redundant recentering.
6183 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
6185 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
6186 Update dependencies.
6188 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6190 Fix a malloc race condition involving strsignal.
6191 A signal can arrive in the middle of a malloc, and Emacs's signal
6192 handler can invoke strsignal, which can invoke malloc, which is
6193 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6194 Fix it by altering the signal handler so that it does not invoke
6196 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6197 * process.c (status_message): Use const pointer, in case strsignal
6198 is #defined to safe_strsignal.
6199 * sysdep.c (sys_siglist, init_signals): Always define and
6200 initialize a substitute sys_siglist if the system does not define
6201 one, even if HAVE_STRSIGNAL.
6202 (safe_strsignal): Rename from strsignal. Always define,
6203 using sys_siglist. Return a const pointer.
6204 * syssignal.h (safe_strsignal): New decl.
6205 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6207 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6209 * w32proc.c (timer_loop): Fix code that waits for timer
6210 expiration, to avoid high CPU usage.
6212 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6214 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6215 (sweep_weak_table): Remove redundant prototypes.
6217 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6219 * emacs.c: Move the inclusion of TERM_HEADER after including
6220 windows.h on WINDOWSNT. This avoids compilation problems with
6223 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6225 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6226 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6227 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6228 as the previous version used 'void *'.
6230 * ralloc.c (ROUNDUP): Fix last change.
6231 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6234 * w32proc.c <disable_itimers>: New static flag.
6235 (init_timers): Initialize it to zero, after creating the critical
6236 sections used by the timer threads.
6237 (term_timers): Set to 1 before deleting the critical sections.
6238 (getitimer, setitimer): If disable_itimers is non-zero, return an
6239 error indication without doing anything. Reported by Fabrice
6240 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6241 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6243 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6246 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6247 term_ntproc after all the other bookkeeping, to get timers working
6248 as long as possible.
6250 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6252 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6253 Suggested by Juri Linkov in
6254 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6256 Prefer plain 'static' to 'static inline' (Bug#12541).
6257 With static functions, modern compilers inline pretty well by
6258 themselves; advice from programmers often hurts as much as it helps.
6259 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6260 this change shrinks the text size of the Emacs executable by 1.1%
6261 without affecting CPU significantly in my benchmark.
6262 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

6338 Now 'static', not 'static inline'.
6341 (bidi_copy_it): Do the whole copy with a single memcpy.
6342 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
6344 Revert the FOLLOW-SYMLINKS change for file-attributes.
6345 Doing it right would require several changes to Tramp, and there's
6346 not enough time to get that tested before the freeze today.
6347 * dired.c (directory_files_internal, Ffile_attributes):
6350 * frame.c (x_report_frame_params): Port better to wider ints.
6351 Do not assume that EMACS_UINT is the same width as uprintmax_t,
6352 or that pointers can be printed in 15 decimal digits.
6353 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
6355 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

6389 * vm-limit.c (lim_data): Now size_t.
6390 (check_memory_limits): Adjust prototypes of real_morecore and
6391 __morecore to receive argument of type ptrdiff_t. Use size_t for

6533 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
6534 Suggested by Eli Zaretskii in
6535 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
6537 2012-09-30 Eli Zaretskii <eliz@gnu.org>
6539 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
6540 HAVE_TIMER_SETTIME is defined.
6542 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6544 Profiler improvements: more-accurate timers, overflow checks.
6545 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6546 signal.h, setjmp.h. Include systime.h instead.
6547 (saturated_add): New function.
6548 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
6549 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.

6552 (enum profiler_cpu_running): New enum.
6553 (profiler_cpu_running): Now of that enum type, not bool.
6554 All uses changed to store the new value.
6555 (handle_profiler_signal): Rename from sigprof_handler_1,
6556 for consistency with other handlers. Do not check whether
6557 cpu_log is a hash-table if garbage collecting, since it
6558 doesn't matter in that case.
6559 (deliver_profiler_signal): Rename from sigprof_handler,
6560 for consistency with other handlers.
6561 (setup_cpu_timer): New function, with much of what used to be in
6562 Fprofiler_cpu_start. Check for out-of-range argument.
6563 Prefer timer_settime if available, and prefer
6564 thread cputime clocks, then process cputime clocks, then
6565 monotonic clocks, to the old realtime clock. Use make_timeval
6566 to round more-correctly when falling back to setitimer.
6567 (Fprofiler_cpu_start): Use it.
6568 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6569 Don't assume that passing NULL as the 2nd argument of setitimer
6570 is the same as passing a pointer to all-zero storage.

6572 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6573 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6574 non-fatal signal handlers. Ignore SIGPROF on startup.
6575 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6576 in profiler.c, since sysdep.c now uses it.
6578 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
6579 Suggested by Eli Zaretskii in

6633 * charset.c, charset.h (maybe_unify_char): Now static.
6634 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6635 Since this stuff is now private to charset.c, there's no need for
6636 a public macro and no need to inline by hand.

6669 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>

6708 (sigaction): Rewrite to call sys_signal instead of duplicating its
6710 (sys_kill): Improve commentary.
6712 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6713 consistency with a signature of a signal handler. All callers
6715 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6716 install term_ntproc as a signal handler for SIGABRT, as that
6717 should be done by the dumped Emacs.
6719 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6721 * w32select.c (term_w32select): Protect against repeated
6722 invocation by setting clipboard_owner to NULL after calling

6788 (interruptible_wait_for_termination):
6789 Move these decls from lisp.h to syswait.h, since they use pid_t.
6790 Needed on FreeBSD; see Herbert J. Skuhra in

6840 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6841 fatal_error_backtrace.
6843 * w32proc.c (sys_kill): Undo last change: don't do anything when

6894 Avoid recursive loop if there's a fatal error in the function itself.
6895 * atimer.c (pending_atimers):
6896 * blockinput.h: Don't include "atimer.h"; no longer needed.
6897 (interrupt_input_pending): Remove. All uses removed.
6898 pending_signals now counts both atimers and ordinary interrupts.
6899 This is less racy than having three separate pending-signal flags.
6900 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6902 Rename from their upper-case counterparts BLOCK_INPUT,
6903 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6904 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6905 This makes it easier to access volatile variables more accurately.
6906 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6907 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6908 that's more reliable if the code is buggy and sets
6909 interrupt_input_blocked to a negative value. All uses changed.
6910 * atimer.c (deliver_alarm_signal):
6911 Remove. No need to deliver this to the parent; any thread can
6912 handle this signal now. All uses replaced by underlying handler.
6913 * atimer.c (turn_on_atimers):
6914 * dispnew.c (handle_window_change_signal):
6915 * emacs.c (handle_danger_signal):
6916 * keyboard.c (kbd_buffer_get_event):
6917 Don't reestablish signal handler; not needed with sigaction.
6918 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6920 Rework to avoid unnecessary accesses to volatile variables.
6921 (UNBLOCK_INPUT_TO): Now a function.
6922 (totally_unblock_input, unblock_input): New decls.
6923 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6924 (init_data): Remove. Necessary stuff now done in init_signal.
6925 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6926 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6927 (fatal_error_code): Remove; no longer needed.
6928 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6929 it doesn't always backtrace. All uses changed. No need to reset
6930 signal to default, since sigaction and/or die does that for us now.
6931 Use emacs_raise (FOO), not kill (getpid (), FOO).
6932 (main): Check more-accurately whether we're dumping.
6933 Move fatal-error setup to sysdep.c
6934 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6935 * gtkutil.c (xg_get_file_name, xg_get_font):
6936 Remove no-longer-needed signal-mask manipulation.
6937 * keyboard.c, process.c (POLL_FOR_INPUT):
6938 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6939 * keyboard.c (read_avail_input): Remove.
6940 All uses replaced by gobble_input.
6941 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6942 (kbd_buffer_store_event_hold, gobble_input):
6943 (record_asynch_buffer_change) [USABLE_SIGIO]:
6944 (store_user_signal_events):
6945 No need to mess with signal mask.
6946 (gobble_input): If blocking input and there are terminals, simply
6947 set pending_signals to 1 and return. All hooks changed to not
6948 worry about whether input is blocked.
6949 (process_pending_signals): Clear pending_signals before processing
6950 them, in case a signal comes in while we're processing.
6951 By convention callers now test pending_signals before calling us.
6952 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6953 New functions, to support changes to blockinput.h.
6954 (handle_input_available_signal): Now extern.
6955 (reinvoke_input_signal): Remove. All uses replaced by
6957 (quit_count): Now volatile, since a signal handler uses it.
6958 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6959 All callers changed. Block SIGINT only if not already blocked.
6960 Clear sigmask reliably, even if Fsignal returns, which it can.
6961 Omit unnecessary accesses to volatile var.
6962 (quit_throw_to_read_char): No need to restore sigmask.
6963 * keyboard.c (gobble_input, handle_user_signal):
6964 * process.c (wait_reading_process_output):
6965 Call signal-handling code rather than killing ourselves.
6966 * lisp.h: Include <float.h>, for...
6967 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6968 (pending_signals): Now volatile.
6969 (syms_of_data): Now const if IEEE floating point.
6970 (handle_input_available_signal) [USABLE_SIGIO]:
6971 (terminate_due_to_signal, record_child_status_change): New decls.
6972 * process.c (create_process): Avoid disaster if memory is exhausted
6973 while we're processing a vfork, by tightening the critical section
6975 (send_process_frame, process_sent_to, handle_pipe_signal)
6976 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6978 (send_process): No need for setjmp/longjmp any more, since the
6979 SIGPIPE stuff is now gone. Instead, report an error if errno
6981 (record_child_status_change): Now extern. PID and W are now args.
6982 Return void, not bool. All callers changed.
6983 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6984 Remove. All uses removed. This bug should be fixed now in a
6986 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6987 and record the child status change directly. This avoids the
6988 need to futz with the signal mask.
6989 (process_fatal_action): Move here from emacs.c.
6990 (emacs_sigaction_flags): New function, containing
6991 much of what used to be in emacs_sigaction_init.
6992 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6993 caught by emacs, to make races less likely.
6994 (deliver_process_signal): Rename from handle_on_main_thread.
6996 (BACKTRACE_LIMIT_MAX): Now at top level.
6997 (thread_backtrace_buffer, threadback_backtrace_pointers):
6999 (deliver_thread_signal, deliver_fatal_thread_signal):
7000 New functions, for more-accurate delivery of thread-specific signals.
7001 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
7002 (deliver_arith_signal): Handle in this thread, not
7003 in the main thread, since it's triggered by this thread.
7004 (maybe_fatal_sig): New function.
7005 (init_signals): New arg DUMPING so that we can be more accurate
7006 about whether we're dumping. Caller changed.
7007 Treat thread-specific signals differently from process-general signals.
7008 Block all signals while handling fatal error; that's safer.
7009 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
7011 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
7012 Ignore SIGPIPE unless batch.
7013 (emacs_backtrace): Output backtrace for the appropriate thread,
7014 which is not necessarily the main thread.
7015 * syssignal.h: Include <stdbool.h>.
7016 (emacs_raise): New macro.
7017 * xterm.c (x_connection_signal): Remove; no longer needed
7018 now that we use sigaction.
7019 (x_connection_closed): No need to mess with sigmask now.
7020 (x_initialize): No need to reset SIGPIPE handler here, since
7021 init_signals does this for us now.
7023 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
7025 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
7026 background rect may be larger (Bug#12245).
7028 2012-09-23 Chong Yidong <cyd@gnu.org>
7030 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
7032 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7034 * .gdbinit: Just stop at fatal_error_backtrace.
7035 See Stefan Monnier's request in
7036 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
7037 Remove no-longer-used query of system type.
7039 2012-09-22 Chong Yidong <cyd@gnu.org>
7041 * search.c (Freplace_match): Doc fix (Bug#12325).
7043 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
7045 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
7046 (Fline_end_position): Doc fix.
7048 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
7050 2012-09-22 Chong Yidong <cyd@gnu.org>
7052 * dispextern.h (struct image_type): Add new slot, storing a type
7053 initialization function.
7055 * image.c (define_image_type): Call the image initializer function
7056 if it is defined. Arguments and return value changed.
7057 (valid_image_p, make_image): Callers changed.
7058 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
7059 (gif_type, imagemagick_type, svg_type, gs_type):
7060 Add initialization functions.
7061 (Finit_image_library): Call lookup_image_type.
7062 (CHECK_LIB_AVAILABLE): Macro deleted.
7063 (lookup_image_type): Call define_image_type here, rather than via
7064 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
7065 (syms_of_image): Move define_image_type calls for xbm_type and
7066 pbm_type to lookup_image_type.
7068 2012-09-22 Eli Zaretskii <eliz@gnu.org>
7070 * keyboard.c (timer_check_2): Move calculation of 'timers' and
7071 'idle_timers' from here ...
7072 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
7073 lists, to avoid infloops when the timer does something stupid,
7074 like reinvoke itself with the same or smaller time-out.
7077 2012-09-22 Martin Rudalics <rudalics@gmx.at>
7079 * window.c (Fsplit_window_internal): Handle only Qt value of
7080 Vwindow_combination_limit separately.
7081 (Qtemp_buffer_resize): New symbol.
7082 (Vwindow_combination_limit): New default value.
7085 2012-09-22 Eli Zaretskii <eliz@gnu.org>
7087 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
7088 the new overlay string. (Bug#10159)
7090 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7092 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
7093 or that fprintf is async-signal-safe. POSIX doesn't require
7096 2012-09-22 Chong Yidong <cyd@gnu.org>
7098 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
7101 2012-09-22 Kenichi Handa <handa@gnu.org>
7103 * composite.c (composition_reseat_it): Handle the case that a
7104 grapheme cluster is not covered by a single font (Bug#12352).
7106 2012-09-21 Chong Yidong <cyd@gnu.org>
7108 * image.c (define_image_type): Avoid adding duplicate types to
7109 image_types (Bug#12463). Suggested by Jörg Walter.
7111 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7113 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
7114 (print_load_command_name): Add case LC_DATA_IN_CODE.
7115 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
7117 2012-09-21 Glenn Morris <rgm@gnu.org>
7119 * eval.c (Frun_hook_with_args_until_success)
7120 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
7122 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
7124 * fileio.c (Ffile_selinux_context): Only call freecon when
7125 lgetfilecon succeeded.
7126 (Fset_file_selinux_context): Likewise. (Bug#12444)
7128 2012-09-21 Eli Zaretskii <eliz@gnu.org>
7130 * xdisp.c (try_window_reusing_current_matrix): Under bidi
7131 reordering, locate the cursor by calling set_cursor_from_row; if
7132 that fails, clear the desired glyph matrix before returning a
7133 failure indication to the caller. Fixes leaving garbled display
7134 when fast scrolling with a down-key. (Bug#12403)
7135 (compute_stop_pos_backwards): Fix a typo that caused crashes while
7136 scrolling through multibyte text.
7138 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
7140 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
7141 calling mark_vectorlike since that's the one that marks the window.
7142 (mark_discard_killed_buffers): Mark the final cdr.
7143 * window.h (struct window): Move prev/next_buffers to the
7144 non-standard fields.
7145 * window.c (make_window): Initialize prev/next_buffers manually.
7147 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
7149 Omit unused arg EXPECTED from socket hooks.
7150 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
7151 * nsterm.m (ns_term_init):
7152 * termhooks.h (struct terminal.read_socket_hook):
7153 * w32inevt.c (w32_console_read_socket):
7154 * w32term.c (w32_read_socket):
7155 * xterm.c (XTread_socket):
7156 Omit unused arg EXPECTED. All callers changed.
7157 (store_user_signal_events): Return void, not int, since callers no
7158 longer care about the return value. All uses changed.
7160 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
7162 * w32gui.h (XParseGeometry): Do not declare.
7164 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
7166 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
7167 Ignore 'expected'. See Eli Zaretskii in
7168 <http://bugs.gnu.org/12471#8> (last line).
7170 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
7171 (XParseGeometry): Now static. Substitute extremal values for
7172 values that are out of range.
7174 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7176 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7178 * nsfns.m (XParseGeometry): Remove.
7179 (Fx_create_frame): Call x_set_offset to correctly interpret
7180 top_pos in geometry.
7182 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7183 (Fx_parse_geometry): If there is a space in string, call
7184 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7186 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7188 * search.c (scan_buffer): Use character positions in calls to
7189 region_cache_forward and region_cache_backward, not byte
7190 positions. (Bug#12196)
7192 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7193 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7195 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7196 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7197 emacs_blocked_malloc, now deleted.
7199 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7201 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7202 The workaround was for improving performance on Solaris 2.4, but
7203 is getting in the way now. Emacs will still work if someone is
7204 still running Solaris 2.4 in a museum somewhere; Sun dropped
7205 support for Solaris 2.4 in 2003.
7206 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7207 * process.c (create_process) [HAVE_WORKING_VFORK]:
7208 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7209 since Emacs no longer uses vfork on that platform.
7211 2012-09-17 Glenn Morris <rgm@gnu.org>
7213 * emacs.c: Use COPYRIGHT.
7215 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7217 Remove configure's --without-sync-input option (Bug#12450).
7218 When auditing signal-handling in preparation for cleaning it up,
7219 I found that SYNC_INPUT has race conditions and would be a real
7220 pain to fix. Since it's an undocumented and deprecated
7221 configure-time option, now seems like a good time to remove it.
7222 Also see <http://bugs.gnu.org/11080#16>.
7223 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7224 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7225 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7226 (malloc_hysteresis):
7227 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7228 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7229 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7230 (dont_register_blocks, bytes_used_when_reconsidered)
7231 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7232 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7233 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7234 Remove. All uses removed.
7235 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7236 implementation, one that depends on whether the new macro
7237 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7239 * atimer.c (run_timers, handle_alarm_signal):
7240 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7241 (handle_async_input, process_pending_signals)
7242 (handle_input_available_signal, init_keyboard):
7243 * nsterm.m (ns_read_socket):
7244 * process.c (wait_reading_process_output):
7245 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7246 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7248 * xterm.c (XTread_socket):
7250 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7251 * eval.c (handling_signal): Remove. All uses removed.
7252 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7253 All uses replaced with the SYNC_INPUT version.
7254 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7256 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7259 * font.c (Ffont_shape_gstring): Remove unused local.
7261 2012-09-16 Glenn Morris <rgm@gnu.org>
7263 * Makefile.in (clean): No longer run nextstep's clean.
7265 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7267 (ns-app): Move here from ns.mk, and simplify.
7268 (clean): Simplify nextstep entry.
7269 * ns.mk: Remove file.
7271 2012-09-17 Kenichi Handa <handa@gnu.org>
7273 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7274 not covert the last few charactes.
7276 2012-09-16 Kenichi Handa <handa@gnu.org>
7278 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7279 here, but just check the validity of glyphs in the glyph-string.
7281 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7283 * window.c (Fwindow_parameter, Fset_window_parameter):
7284 Accept any window as argument (Bug#12452).
7286 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7288 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7289 to ns_term_init to avoid memory leak.
7291 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7292 explicit retain/release.
7293 (ns_term_init): Only allow one display. Initialize outerpool and
7296 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7298 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7299 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7300 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7301 the Microsoft problem in a different way, by altering ../nt/config.nt.
7303 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7318 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7319 by lisp.h. This completes removal of setjmp.h inclusion
7320 erroneously announced in the previous commit. (Bug#12446)
7322 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7325 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7326 not defined as a macro. The latter happens on MS-Windows.
7329 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7331 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7332 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7333 Some instances of '#include <setjmp.h>' removed, if the
7334 only reason for the instance was because "lisp.h" was included.
7335 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7336 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7337 and _longjmp with the new symbols. Emacs already uses _setjmp if
7338 available, so this change affects only POSIXish hosts that have
7339 sigsetjmp but not _setjmp, such as some versions of Solaris and
7340 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7341 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7342 (png_load_body) [HAVE_PNG]:
7343 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7344 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7345 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7346 since PNG requires jmp_buf. This is the only exception to the
7347 general rule that we now use sys_setjmp and sys_longjmp.
7348 This exception is OK since this code does not change the signal
7349 mask or longjmp out of a signal handler.
7351 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7353 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7354 Include "syssignal.h", for 'main_thread'.
7356 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7358 Avoid out-of-range marker position (Bug#12426).
7359 * insdel.c (replace_range, replace_range_2):
7360 Adjust markers before overlays, as suggested by comments.
7361 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7362 Remove redundant check before calling offset_intervals.
7364 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7366 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7367 current buffer (Bug#12387).
7369 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7371 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7373 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7375 Use a more backwards-compatible timer format (Bug#12430).
7376 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7377 vector element, not from the 4th, since PSECS is now at the end.
7378 (Fcurrent_idle_time): Doc fix.
7380 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7382 Function to mark objects and remove killed buffers at once.
7383 * alloc.c (discard_killed_buffers): Rename to ...
7384 (mark_discard_killed buffers) ... new name. Add marking
7385 of remaining objects. Fix comment. Adjust users.
7386 (mark_object): Do not touch frame buffer lists here.
7387 * frame.c (delete_frame): Reset frame buffer lists here.
7389 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7391 Better workaround for GNOME bug when --enable-gcc-warnings.
7392 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7393 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7394 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7396 Simplify SIGIO usage (Bug#12408).
7397 The code that dealt with SIGIO was crufty and confusing, e.g., it
7398 played tricks like "#undef SIGIO" but these tricks were not used
7399 consistently. Simplify mostly by not #undeffing standard symbols,
7400 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7401 or not as we please) rather than "defined SIGIO" (standard symbol
7402 that we probably shouldn't #undef).
7403 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7404 Modules that need it can include it.
7405 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7406 * dispextern.h (ignore_sigio): New decl.
7407 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7408 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7409 * emacs.c (shut_down_emacs):
7410 * keyboard.c (kbd_buffer_store_event_hold):
7411 Use ignore_sigio rather than invoking 'signal' directly.
7412 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7414 (FIONREAD, SIGIO): Do not #undef.
7415 (tty_read_avail_input): Use #error rather than a syntax error.
7416 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7417 for I_PIPE, used by SETUP_SLAVE_PTY.
7418 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7419 * sysdep.c (croak): Remove; no longer needed. This bit of
7420 temporary code, with Fred N. Fish's comment that it's temporary,
7421 has been in Emacs since at least 1992!
7422 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7423 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7424 * syssignal.h (croak): Remove decl.
7425 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7426 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7427 now that we're termios-only.
7428 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7429 * term.c (dissociate_if_controlling_tty): Use #error rather than
7432 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7433 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7434 to work around GNOME bug 683906.
7435 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7436 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7437 This works around GCC bug 54561.
7439 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7441 More fixes for 'volatile' and setjmp/longjmp.
7442 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7443 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7444 (png_load_body) [HAVE_PNG]:
7445 (jpeg_load_body) [HAVE_JPEG]:
7446 New function, with most of the old parent function's body.
7447 (png_load) [HAVE_PNG]:
7448 (jpeg_load) [HAVE_JPEG]:
7449 Invoke the new function, to avoid longjmp munging our locals.
7450 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7451 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7452 longjmp is passed 2, as the C standard doesn't guarantee this.
7453 Instead, store the failure code into mgr->failure_code.
7455 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7457 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7458 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7459 (syms_of_keyboard): Remove support for unread-command-char.
7461 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7463 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7464 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7465 violation. (Bug#12426)
7467 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7469 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7471 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7473 * eval.c: Add `inhibit-debugger'.
7474 (Qinhibit_debugger): New symbol.
7475 (call_debugger): Bind it instead of Qdebug_on_error.
7476 (maybe_call_debugger): Test Vinhibit_debugger.
7477 (syms_of_eval): Define inhibit-debugger.
7478 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7479 (syms_of_xdisp): Remove inhibit-debug-on-message.
7481 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7483 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7484 If a nonvolatile local variable is written before a _longjmp to
7485 the frame containing the variable, and is read after the _longjmp,
7486 the value read is indeterminate. Some local variables of type
7487 'struct handler' and 'struct catchtag' are used in this way, so
7488 mark each of their slots as volatile if the slot can be set before
7489 _longjmp and read afterwards.
7490 * lisp.h (struct handler): var and chosen_clause are now volatile.
7491 (struct catchtag): val, next, and pdlcount are now volatile.
7493 * bidi.c (bidi_push_it, bidi_pop_it):
7494 * fns.c (copy_hash_table):
7495 * image.c (define_image_type):
7496 * keyboard.c (kbd_buffer_store_event_hold):
7497 * process.c (Fprocess_send_eof):
7498 * xfaces.c (x_create_gc) [HAVE_NS]:
7499 * xgselect.c (xg_select):
7500 Prefer assignment to memcpy when either will do.
7502 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7503 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7504 time an item is removed. No need to mark this function 'inline';
7505 the compiler knows better than we do.
7507 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7509 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7510 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7511 to change_frame_size (Bug#12388).
7512 (windowDidResize:): Pass YES to updateFrameSize.
7514 * nsterm.h: Add delay parameter to updateFrameSize.
7516 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7518 Discard killed buffers from deleted window and frame objects.
7519 This reduces an amount of references to killed buffers and
7520 helps GC to reclaim them faster.
7521 * alloc.c (discard_killed_buffers): New function.
7522 (mark_object): Use it for deleted windows and frames.
7523 (mark_object): If symbol's value is set up for a killed buffer
7524 or deleted frame, restore its global binding.
7525 * data.c (swap_in_global_binding): Add GC notice.
7526 (swap_in_symval_forwarding): Use convenient set_blv_where.
7527 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7528 * window.h: ... to here.
7530 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7532 Convenient macro to check whether the buffer is live.
7533 * buffer.h (BUFFER_LIVE_P): New macro.
7534 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7535 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7537 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7539 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7540 composition cases (Bug#12364).
7542 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7543 overhang of succeeding glyphs overlapping box cursor.
7545 * w32term.c (x_draw_glyph_string): Likewise.
7547 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7549 Simplify, document, and port floating-point (Bug#12381).
7550 The porting part of this patch fixes bugs on non-IEEE platforms
7551 with frexp, ldexp, logb.
7552 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7554 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7555 support, by removing commented-out code and briefly listing the
7556 C89 functions excluded. The commented-out stuff was confusing
7557 maintenance, e.g., we thought we needed cbrt but it was commented out.
7558 (logb): Remove decl; no longer needed.
7559 (isfinite): New macro, if not already supplied.
7560 (isnan): Don't replace any existing macro.
7561 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7562 are present on all C89 platforms.
7563 (Ffrexp): Do not special-case zero, as frexp does the right thing
7565 (Flogb): Do not use logb, as it doesn't have the desired meaning
7566 on hosts that use non-base-2 floating point. Instead, stick with
7567 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7568 frexp, to avoid getting an unspecified result.
7570 * xdisp.c (Qinhibit_debug_on_message): Now static.
7572 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7574 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7575 NSBezierPath (Bug#12131).
7577 2012-09-10 Chong Yidong <cyd@gnu.org>
7579 * fns.c (Fdelq, Fdelete): Doc fix.
7581 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7583 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7584 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7586 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7588 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7589 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7592 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7594 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7595 left fringe if the window has a left margin. This avoids leaving
7596 traces of the cursor because its leftmost pixel is not drawn over.
7598 * dispnew.c (update_window_line): When the left margin area of a
7599 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7600 that screen line. (Bug#12277)
7602 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7604 Assume C89 or later for math functions (Bug#12381).
7605 This simplifies the code, and makes it a bit smaller and faster,
7606 and (most important) makes it easier to clean up signal handling
7607 since we can stop worring about floating-point exceptions in
7608 library code. That was a problem before C89, but the problem
7609 went away many years ago on all practical Emacs targets.
7610 * data.c, image.c, lread.c, print.c:
7611 Don't include <math.h>; no longer needed.
7612 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7613 might be autoconfigured, as that never happens.
7615 * doprnt.c (DBL_MAX_10_EXP):
7616 * print.c (DBL_DIG):
7617 Remove. C89 or later always defines these.
7618 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7619 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7620 (arith_error, domain_error, domain_error2):
7621 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7622 no longer needed -- we simply return what C returns. All uses removed.
7623 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7625 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7626 Remove. All uses expanded, as these macros are no longer used
7627 more than once and are now more trouble than they're worth.
7628 (Ftan): Use tan, not sin / cos.
7629 (Flogb): Assume C89 frexp.
7630 (fmod_float): Assume C89 fmod.
7631 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7632 (init_floatfns): Remove. All uses removed.
7634 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7636 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7637 compositeToPoint for OSX < 10.6 (Bug#12390).
7639 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7641 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7642 This produces more-accurate results.
7644 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7646 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7647 changes (Bug#12088).
7649 2012-09-08 Chong Yidong <cyd@gnu.org>
7651 * syntax.c (Fstring_to_syntax): Doc fix.
7653 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7655 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7656 in the internal border.
7657 (x_set_window_size): Remove static variables and their usage.
7658 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7659 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7660 Remove fringe/internal border adjustment (Bug#11052).
7661 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7662 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7663 (ns_fix_rect_ibw): Remove.
7664 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7665 (ns_dumpglyphs_box_or_relief): Ditto.
7666 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7668 (ns_dumpglyphs_image): Ditto.
7669 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7671 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7672 their usage. Add fringe_extended_p and its use as in other terms.
7673 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7674 scroll bar was removed.
7675 (updateFrameSize): New function.
7676 (windowDidResize): Move code to updateFrameSize and call it.
7678 * nsterm.h (EmacsView): Add updateFrameSize.
7680 2012-09-07 Chong Yidong <cyd@gnu.org>
7682 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7684 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7686 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7688 More signal-handler cleanup (Bug#12327).
7689 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7690 Problem introduced when merging patches. Noted by Eli Zaretskii in
7691 <http://bugs.gnu.org/12327#67>.
7692 * floatfns.c: Comment fix.
7693 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7694 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7695 and anyway the declaration is harmless even if SIGDANGER is not defined.
7696 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7697 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7698 source files not surprisingly expected syssignal.h to define, or
7699 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7700 Include <sys/ioctl.h>, for FIONREAD.
7701 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7702 This eliminates a problem whereby other files mysteriously had
7703 to include "syssignal.h" before including "systty.h" if they
7704 wanted to use "#ifdef SIGIO".
7706 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7708 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7710 * w32.c (sigemptyset): Empty the set.
7711 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7713 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7715 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7717 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7718 (mark_object): Likewise for frame objects.
7720 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7722 * syssignal.h (handle_on_main_thread): Always declare,
7723 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7724 This ports to platforms without HAVE_PTHREAD.
7726 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7728 Signal-handler cleanup (Bug#12327).
7729 Emacs's signal handlers were written in the old 4.2BSD style with
7730 sigblock and sigmask and so forth, and this led to some
7731 inefficiencies and confusion. Rewrite these to use
7732 pthread_sigmask etc. without copying signal sets around. Also,
7733 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7734 'signal', and instead use functions that do not attempt to take
7735 over the system name space. This patch causes Emacs's text
7736 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7737 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7738 Do not include <signal.h> or "syssignal.h", as these
7739 modules do not use signals.
7740 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7741 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7742 Do not include <signal.h>, as "syssignal.h" does that for us now.
7743 * atimer.c (sigmask_atimers): New function.
7744 (block_atimers, unblock_atimers): New functions,
7745 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7747 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7748 no longer needed here.
7749 * emacs.c (main): Inspect existing signal handler with sigaction,
7750 so that there's no need to block and unblock SIGHUP.
7751 * sysdep.c (struct save_signal): New member 'action', replacing
7752 old member 'handler'.
7753 (save_signal_handlers, restore_signal_handlers):
7754 Use sigaction instead of 'signal' to save and restore.
7755 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7756 New function. All users of 'signal' modified to use set_sighandler
7757 if they're writeonly, and to use sys_signal if they're read+write.
7758 (emacs_sigaction_init, forwarded_signal): New functions.
7759 (sys_signal): Remove. All uses replaced by calls to sigaction
7760 and emacs_sigaction_init, or by direct calls to 'signal'.
7761 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7762 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7763 all uses replaced by pthread_sigmask etc. calls.
7764 * syssignal.h: Include <signal.h>.
7765 (emacs_sigaction_init, forwarded_signal): New decls.
7766 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7767 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7768 (sigmask, sys_sigmask): Remove; no longer needed.
7769 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7770 (sigblock, sigunblock, sigfree):
7771 (sigsetmask) [!defined sigsetmask]:
7772 Remove. All uses replaced by pthread_sigmask.
7773 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7774 no longer need to be replaced, and its typical old uses
7775 are now done via emacs_sigaction_init and sigaction.
7776 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7777 (sys_sigdel): Remove; unused.
7778 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7780 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7782 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7783 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7785 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7787 Explicitly mark buffer_defaults and buffer_local_symbols.
7788 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7789 mark_local_symbols here.
7790 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7791 since special buffers aren't marked here any more.
7792 (allocate_buffer): Chain new buffer with all_buffers here...
7793 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7795 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7796 (syms_of_buffer): Remove staticpro of the above.
7797 (init_buffer_once): Set names for buffer_defaults and
7798 buffer_local_symbols.
7800 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7802 Use bool for booleans in font-related modules.
7803 * font.c (font_intern_prop, font_style_to_value)
7804 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7805 (generate_otf_features, font_check_otf_features, font_check_otf)
7806 (font_match_p, font_list_entities, font_at):
7807 * fontset.c (fontset_id_valid_p, reorder_font_vector
7808 (fontset_find_font, Fset_fontset_font)
7809 (face_suitable_for_char_p) [0]:
7810 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7811 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7812 (m17n_flt_initialized, ftfont_shape_by_flt):
7813 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7814 * nsfont.m (nsfont_draw):
7815 * w32font.c (w32font_draw):
7816 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7817 Use bool for booleans.
7818 * font.h: Adjust to above API changes.
7819 (struct font, struct font_driver, struct font_driver_list):
7820 Use bool for booleans.
7821 (struct font): Remove useless member encoding_type.
7823 * fontset.c, xftfont.c: Omit unnecessary static decls.
7825 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7827 * alloc.c (mark_object): Revert window marking code
7828 since it's unsafe for the Fset_window_configuration.
7830 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7832 Fix race conditions with signal handlers and errno (Bug#12327).
7833 Be more systematic about preserving errno whenever a signal
7834 handler returns, even if it's not in the main thread. Do this by
7835 renaming signal handlers to distinguish between signal delivery
7836 and signal handling. All uses changed.
7837 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7838 * data.c (deliver_arith_signal): Rename from arith_error.
7839 * dispnew.c (deliver_window_change_signal): Rename from
7840 window_change_signal.
7841 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7842 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7843 * keyboard.c (deliver_input_available_signal): Rename from
7844 input_available_signal.
7845 (deliver_user_signal): Rename from handle_user_signal.
7846 (deliver_interrupt_signal): Rename from interrupt_signal.
7847 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7848 (deliver_child_signal): Rename from sigchld_handler.
7849 * atimer.c (handle_alarm_signal):
7850 * data.c (handle_arith_signal):
7851 * dispnew.c (handle_window_change_signal):
7852 * emacs.c (handle_fatal_signal, handle_danger_signal):
7853 * keyboard.c (handle_input_available_signal):
7854 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7855 * process.c (handle_pipe_signal, handle_child_signal):
7856 New functions, with the actual signal-handling code taken from the
7857 original respective signal handlers, sans the sporadic attempts to
7858 preserve errno, since that's now done by handle_on_main_thread.
7859 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7860 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7861 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7863 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7864 Move initialization of main_thread to sysdep.c's init_signals.
7865 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7866 our usage, and simplifies the mainline code.
7867 (record_child_status_change): New static function, as a helper
7868 for handle_child_signal, and with most of the old child handler's
7870 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7871 (handle_child_signal): Use the above.
7872 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7873 Moved here from emacs.c.
7874 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7875 code moved here from emacs.c's main function.
7876 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7877 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7878 This lets callers save and restore errno properly.
7880 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7882 Remove redundant or unused things here and there.
7883 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7884 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7885 * editfns.c (Fcompare_buffer_substrings): Likewise.
7886 * frame.h (struct terminal, struct font_driver_list):
7887 Remove redundant declarations.
7888 * window.h (Qleft, Qright): Likewise.
7890 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7892 Do not mark objects from deleted buffers, windows and frames.
7893 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7894 (mark_object): Likewise for windows and frames.
7896 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7898 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7899 buffer_defaults and buffer_local_symbols as valid objects.
7900 Return special value to denote them.
7902 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7904 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7905 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7906 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7907 (file_name_absolute_p, Fsubstitute_in_file_name):
7908 (check_executable, check_writable, Ffile_accessible_directory_p)
7909 (Fset_file_selinux_context, Fdefault_file_modes)
7910 (Finsert_file_contents, choose_write_coding_system)
7911 (Fwrite_region, build_annotations, a_write, e_write)
7913 * filelock.c (boot_time_initialized, get_boot_time)
7914 (get_boot_time_1, lock_file_1, within_one_second):
7915 * floatfns.c (in_float):
7916 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7917 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7918 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7919 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7920 * window.c (compare_window_configurations):
7921 Use bool for booleans.
7922 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7923 (Fdefault_file_modes): Now mode_t, not int, for modes.
7924 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7925 (internal_delete_file): Now returns void, not a (boolean) int,
7926 since nobody was looking at the return value.
7927 * lisp.h, window.h: Adjust to above API changes.
7929 * xdisp.c (set_message): Simplify and reindent last change.
7931 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7933 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7935 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7937 * eval.c (call_debugger): Make the function non-static so that we
7938 can call it from set_message.
7940 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7941 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7943 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7945 Give more-useful info on a fatal error (Bug#12328).
7946 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7947 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7948 of doing the work ourselves.
7949 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7950 do most of the work.
7951 (fatal_error_backtrace): New function, taken from the guts
7952 of the old fatal_error_signal, but with a new option to output
7954 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7955 info about the signal than just its number.
7956 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7957 * sysdep.c: Include <execinfo.h>
7958 (emacs_backtrace): New function, taken partly from the previous
7959 code of the 'die' function.
7960 (emacs_abort): Call fatal_error_backtrace rather than abort.
7962 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7964 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7965 eager (load-time) macro-expansion.
7966 * lisp.mk (lisp): Add macroexp.
7968 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7970 Simplify redefinition of 'abort' (Bug#12316).
7971 Do not try to redefine the 'abort' function. Instead, redo
7972 the code so that it calls 'emacs_abort' rather than 'abort'.
7973 This removes the need for the NO_ABORT configure-time macro
7974 and makes it easier to change the abort code to do a backtrace.
7975 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7976 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7977 Remove; sysdep.c's emacs_abort now takes its place.
7978 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7979 'abort' changed to use 'emacs_abort'.
7980 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7981 (abort) [!defined abort]: Rename to ...
7982 (emacs_abort): ... new name.
7983 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7984 the place of the old 'abort' in emacs.c.
7985 * w32.c, w32fns.c (abort): Do not #undef.
7986 * w32.c (emacs_abort): Rename from w32_abort.
7988 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7990 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7991 offsets[j].dv, since the y axis of the screen coordinates points
7992 down, while the y axis of the font definition coordinates points
7993 up. This fixes display of Arabic diacritics such as KASRA and
7994 KASRATAN. (Bug#11860)
7996 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7998 Be more systematic about _setjmp vs setjmp.
7999 * alloc.c (test_setjmp, mark_stack):
8000 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
8001 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
8002 (png_load, my_error_exit, jpeg_load):
8003 * process.c (send_process_trap, send_process):
8004 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
8005 The underscored versions are up to 30x faster on some hosts.
8006 Formerly, the code used setjmp+longjmp sometimes and
8007 _setjmp+_longjmp at other times, with no particular reason to
8008 prefer setjmp+longjmp.
8010 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
8012 Fix minor problem found by static checking.
8013 * buffer.c (Fdelete_all_overlays): Return nil.
8015 2012-09-03 Martin Rudalics <rudalics@gmx.at>
8017 * buffer.c (Fdelete_all_overlays): New function.
8019 2012-09-03 Chong Yidong <cyd@gnu.org>
8021 * gtkutil.c: Add extern decl for Qxft.
8023 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
8025 * emacs.c, eval.c: Use bool for boolean.
8026 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
8027 (malloc_using_checking) [DOUG_LEA_MALLOC]:
8028 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
8029 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
8030 (main, decode_env_path, Fdaemon_initialized):
8031 * eval.c (call_debugger, Finteractive_p, interactive_p):
8032 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
8033 (maybe_call_debugger, Fbacktrace):
8034 * process.c (read_process_output, exec_sentinel):
8035 Use bool for booleans.
8036 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
8037 All callers changed.
8038 * eval.c (interactive_p): Omit always-true boolean argument
8039 EXCLUDE_SUBRS_P. All callers changed.
8040 * dispextern.h, lisp.h: Reflect above API changes.
8041 * firstfile.c (dummy): Use the address of 'main', whose signature
8042 won't change, instead of the address of 'initialize', whose
8043 signature just changed from int to bool.
8044 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
8045 * msdos.c (fatal_error_in_progress): ... from here.
8046 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
8048 (redisplay_internal, unwind_redisplay): Simply clear
8049 REDISPLAYING_P when unwinding, instead of saving its previous,
8050 always-false value and then restoring it.
8052 Clean up some extern decls.
8053 Mostly, this hoists extern decls out of .c files and into .h files.
8054 That way, we're more likely to catch errors if the interfaces change.
8055 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
8056 declare xg_mark_data.
8057 * dispextern.h (x_frame_parm_handlers):
8059 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
8060 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
8061 (Qultra_bold, Qoblique, Qitalic):
8062 Move extern decl here from .c file.
8063 * alloc.c (xg_mark_data) [USE_GTK]:
8065 * eval.c (Qlexical_binding):
8066 * fns.c (time) [!HAVE_UNISTD_H]:

8072 * process.c (QCfamily, QCfilter):
8073 * widget.c (free_frame_faces):
8074 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
8075 * xfont.c (x_clear_errors):
8076 * xterm.c (x_frame_parm_handlers):
8077 Remove now-redundant extern decls.
8078 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
8079 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
8081 * xfaces.c: Remove unnecessary static decls.
8082 * xterm.c (updating_frame): Remove decl of nonexistent object.
8084 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
8085 when building globals.h, as the objects that are not built on
8086 this host are not needed to compile C files on this host.
8088 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
8090 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
8092 * frame.h: Add missing prototype for x_wm_set_size_hint.
8094 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

8098 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
8099 (Fsubstitute_command_keys):

8104 (make_buffer_string, make_buffer_string_both)
8105 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

8128 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
8130 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
8131 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

8136 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
8138 2012-09-01 Eli Zaretskii <eliz@gnu.org>
8140 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
8141 more than one grapheme cluster passed to the shaper: compute the
8142 offset adjustment values separately for each cluster. (Bug#11860)
8144 * image.c: Restore mistakenly removed inclusion of w32.h. Without
8145 it, GCC doesn't see prototypes of w32_delayed_load, and complains
8146 about implicit conversions from integer to pointer.
8148 2012-09-01 Daniel Colascione <dancol@dancol.org>
8150 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
8151 system used too early.
8153 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
8155 Better seed support for (random).
8156 * emacs.c (main): Call init_random.
8157 * fns.c (Frandom): Set the seed from a string argument, if given.
8158 Remove long-obsolete Gentzel cruft.

8160 (init_random): New function.
8162 2012-09-01 Daniel Colascione <dancol@dancol.org>
8164 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
8165 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
8166 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
8167 x_wm_set_size_hint, x_query_colors, x_real_positions,
8168 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
8169 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
8170 all of which have been moved to common code.
8172 * xfaces.c: Include TERM_HEADER instead of listing all possible
8173 window-system headers.
8175 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
8178 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
8179 directly accessing frame internals.
8181 * w32font.h: Include font.h. Define syms_of_w32font and
8184 * process.c: Include TERM_HEADER instead of listing all possible
8185 window-system headers.
8187 * nsterm.h: Remove declarations now in frame.h.
8188 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
8190 * menu.c: Include TERM_HEADER instead of listing all possible
8191 window-system headers.
8193 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
8196 * keyboard.c: Include TERM_HEADER instead of listing all possible
8197 window-system headers.
8199 * image.c: Include TERM_HEADER instead of listing all possible
8200 window-system headers. Declare Vlibrary_cache when compiling for
8203 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
8204 window system declarations.
8206 * frame.h: Move common functions here: set_frame_menubar,
8207 x_set_window_size, x_sync, x_get_focus_frame,
8208 x_set_mouse_position, x_set_mouse_pixel_position,
8209 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

8220 window-system headers.
8222 * emacs.c: Include TERM_HEADER.
8224 * dispnew.c: Include TERM_HEADER instead of listing all possible
8225 window-system headers.
8227 * ccl.h: Include character.h.
8229 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
8230 the current window system; include in list of objects to link into
8233 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8235 Remove mark_ttys function and fix tty_display_info initialization.
8236 * lisp.h (mark_ttys): Remove prototype.
8237 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8238 to mark_ttys because all possible values of 'top_frame' slot are
8239 the frames which are reachable from Vframe_list.
8240 * term.c (mark_ttys): Remove.
8241 (init_tty): Safely initialize 'top_frame' slot with Qnil.

8254 Remove unused member of struct x_output and struct w32_output.
8255 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
8256 * w32term.h (struct w32_output): Likewise.
8258 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
8260 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
8261 does not become zero (Bug#12234).
8263 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
8265 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
8266 for GCC 4.7.1 x86-64.
8268 2012-08-30 Glenn Morris <rgm@gnu.org>
8270 * lread.c (init_lread): For out-of-tree builds, only add the
8271 source directory's site-lisp dir to the load-path if it exists,
8272 consistent with in-tree builds. (Bug#12302)
8274 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
8276 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
8277 button_values to NULL. Call setStykeMask so dialogs get a close button.
8278 (windowShouldClose:): Set window_closed.
8279 (dealloc): New member, free button_values.
8280 (process_dialog:): Make member function. Remove window argument,

8289 (initFromContents:isQuestion:): Adjust call to process_dialog.
8290 Code formatting change.
8291 (timeout_handler:): Set timer_fired to YES.
8292 (runDialogAt:): Set timer_fired to NO.
8293 Handle click on close button as quit.
8295 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8296 Add window_closed and button_values. Add void as return value for
8297 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8298 Add process_dialog as new member.
8300 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8302 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
8303 is not one of the heaps we manage. (Bug#12242)
8305 2012-08-28 Glenn Morris <rgm@gnu.org>
8307 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

8319 if the buffer is dead.
8320 (Fother_buffer, other_buffer_safely): Remove redundant
8323 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
8325 Always use set_buffer_if_live to restore original buffer at unwind.

8363 (change_frame_size_1, sit_for):
8364 Use bool for boolean.
8365 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
8366 and remove last int (actually boolean) argument, which was always 0.
8367 All callers changed.
8368 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
8369 * dispextern.h (struct composition_it): Use bool for boolean.
8370 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
8371 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
8372 * dired.c (file_name_completion):
8373 Use bool for boolean. (This was missed in an earlier change.)
8375 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8377 * window.c (Fset_window_configuration): Revert first part of
8380 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
8382 * nsterm.h (NSPanel): New class variable dialog_return.
8384 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
8385 Initialize dialog_return.
8386 (windowShouldClose:): Use stop instead of stopModalWithCode.
8387 (clicked:): Ditto, and also set dialog_return (Bug#12258).
8388 (timeout_handler:): Use stop instead of abortModal. Send a dummy
8390 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

8405 Use bool for booleans.
8406 * dired.c (file_name_completion):
8407 * process.h (fd_callback):
8408 Omit int (actually boolean) argument. It wasn't being used.

8435 Use bool for booleans.
8436 * coding.h, lisp.h: Reflect above API changes.
8437 * coding.c: Remove unnecessary static function decls.
8438 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8439 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8440 not a boolean 'int', since callers never look at the return value.
8441 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8442 * coding.h (decoding_buffer_size, encoding_buffer_size)
8443 (emacs_mule_string_char): Remove unused extern decls.
8444 (struct iso_2022_spec, struct coding_system):

8450 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8452 Fix spare memory change (Bug#12286).
8453 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8454 (valid_lisp_object_p): Likewise.
8456 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8458 * window.c (Fset_window_configuration): Record any window's old
8459 buffer if it's replaced (see Bug#8789). If the new current
8460 buffer doesn't appear in the selected window, go to its old
8463 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8465 Special MEM_TYPE_SPARE to denote reserved memory.
8466 * alloc.c (enum mem_type): New memory type.
8467 (refill_memory_reserve): Use new type for spare memory.
8468 This prevents live_cons_p and live_string_p from incorrect
8469 detection of uninitialized objects from spare memory as live.
8471 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8474 * Makefile.in (.PHONY): versioclean -> versionclean.
8476 Remove unused external symbols.
8477 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8478 * window.c (Qwindow_valid_p, decode_valid_window):
8479 Now static, not extern.
8480 * data.c (Qinterval): Remove; unused.
8481 (syms_of_data): Do not define 'interval'.
8482 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8483 * window.h (decode_valid_window):
8486 * character.c, charset.c, chartab.c: Use bool for booleans.

8497 (map_sub_char_table):
8498 Use bool for boolean.
8499 * character.c (str_to_unibyte): Omit last boolean argument; it was
8500 always 0. All callers changed.
8501 * character.h, charset.h: Adjust to match previous changes.
8502 * character.h (char_printable_p): Remove decl of nonexistent function.
8503 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8504 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8505 are all boolean, so make them single-bit bitfields.
8507 * lisp.h (ASET): Remove attempt to detect side effects.
8508 It was meant to be temporary and it often doesn't work,
8509 because when IDX has side effects the behavior of IDX==IDX
8510 is undefined. See Stefan Monnier in
8511 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8513 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8515 * lisp.h (functionp): New function (extracted from Ffunctionp).
8516 (FUNCTIONP): Use it.
8517 * eval.c (Ffunctionp): Use it.
8519 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8521 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8522 as that's faster and simpler than static storage. Don't bother
8523 with the g_main_context_query overhead if g_main_context_pending
8524 says no events are pending.
8525 (gfds, gfds_size): Remove these static vars.
8526 (xgselect_initialize): Remove; no longer needed.
8527 All uses and decls removed.
8529 * emacs.c (fatal_error_signal_hook): Remove.
8530 All uses removed. This leftover from old code was always 0.
8532 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8533 * casefiddle.c (casify_object, casify_region):
8534 * casetab.c (set_case_table):
8535 * category.c, category.h (word_boundary_p):
8536 * category.h (CHAR_HAS_CATEGORY):
8537 Use bool for booleans, instead of int.
8539 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8541 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8543 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8545 On assertion failure, print backtrace if available.
8546 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8547 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8548 * Makefile.in (LIB_EXECINFO): New macro.
8551 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8552 * bytecode.c (exec_byte_code):
8553 * callint.c (check_mark, Fcall_interactively):
8554 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8555 (getenv_internal, sync_process_alive, call_process_exited):
8556 * lisp.h (USE_SAFE_ALLOCA):
8557 Use bool for booleans, instead of int.
8558 * lisp.h, process.h: Adjust prototypes to match above changes.
8559 * callint.c (Fcall_interactively): Don't assume the mark's
8560 offset fits in 'int'.
8562 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8564 * buffer.c, buffer.h: Use bool for boolean.

8571 (mmap_enlarge, mmap_set_vars):
8572 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8573 Use bool for booleans, instead of int.
8574 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8575 since the 1-or-0 return value is always ignored anyway.
8576 (mmap_initialized_p):
8577 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8578 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8580 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8582 * bidi.c: Use bool for boolean.
8583 This is a bit more readable, and makes the text segment of bidi.o
8584 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8585 Presumably it's faster too.
8586 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

8594 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8595 (bidi_unshelve_cache): Adjust decls to match code.

8609 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8610 compile time tests instead of run time tests on systems that do
8612 (FRAME_MAC_P): Remove leftover from deleted code.
8613 * frame.c (syms_of_frame): Remove leftover from deleted code.
8615 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8617 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8619 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8621 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8622 Otherwise, the compiler complains about (A?B:C) where B is void
8623 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8624 (fontset_add): Return void, for FONTSET_ADD.
8626 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8628 * alloc.c: Use bool for booleans.
8629 (gc_in_progress, abort_on_gc)

8636 (mark_stack, valid_pointer_p, make_pure_string)
8637 (Fgarbage_collect, survives_gc_p, gc_sweep):
8638 Use bool for booleans, instead of int.
8639 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8640 Remove unused local.
8641 * alloc.c (PURE_POINTER_P):
8642 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.

8649 * lread.c (readchar, read1):
8650 * print.c (Fprin1_to_string):
8651 * xdisp.c (push_message):
8652 Use bool for booleans affected directly or indirectly by
8655 Make recently-introduced setters macros.
8656 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8657 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8658 (set_fontset_default, set_fontset_fallback): Rename from their
8659 upper-case counterparts, and make them functions rather than macros.
8660 This is more consistent with the other recently-introduced setters.
8661 These don't need to be inline, since they're local.
8663 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8665 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

8668 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8670 * lisp.h (vcopy): Use memcpy rather than our own loop.
8671 This fixes a performance regression introduced by the recent
8672 addition of vcopy. This means 'vcopy' will need to be modified
8673 for a copying collector, but that's OK. Also, tighten the
8674 checking in the assertion.
8676 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8678 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8679 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8680 non-base glyph for the width of the base character, according to
8681 what x_draw_composite_glyph_string_foreground expects.
8682 Generate WADJUST value according to composition_gstring_width's
8683 expectations, to produce correct width of the composed character.
8684 Reverse the sign of the DU offset produced by ScriptPlace.
8686 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8688 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

8716 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8719 2012-08-20 Glenn Morris <rgm@gnu.org>
8721 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8722 Don't assume that `ln -f' works.
8724 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8726 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8727 and later about non-assignments with no effect. See discussion at
8728 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for

8752 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8753 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8754 (set_hash_key_and_value, set_hash_index, set_hash_next)
8755 (set_hash_hash): New functions.
8756 * charset.c, fns.c: Adjust users.

8768 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8770 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8772 Rely on <config.h> + <unistd.h> to declare 'environ',
8773 as gnulib does this if the system doesn't.
8774 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8775 Remove declaration. MS-Windows declares it on stdlib.h which is
8776 included by conf_post.h.
8777 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8778 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8779 * vm-limit.c: Include <unistd.h>, for 'environ'.
8781 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8782 (start_of_data): Remove decl; mem-limits.h provides it.
8784 * xdisp.c (handle_invisible_prop): Make it a bit faster
8785 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8787 2012-08-19 Chong Yidong <cyd@gnu.org>
8789 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string

8798 (Fkill_local_variable): Likewise.
8800 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8802 * nsfont.m (ns_ascii_average_width): Ensure the string
8803 ascii_printable is initialized with a null-terminated character

8808 port new setting code to Sun C 5.8 2005/10/13
8809 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8810 Return void, not Lisp_Object. Otherwise, the compiler
8811 complains about (A?B:C) where B is void and C is Lisp_Object
8812 when compiling CHAR_TABLE_SET, due to the recent change to
8813 the API of sub_char_table_set_contents.
8815 2012-08-18 Chong Yidong <cyd@gnu.org>
8817 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

9645 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
9646 * w32.c (init_environment): Change the default values of many
9647 environment variables in dflt_envvars[] to NULL, to avoid pushing
9648 them into environment when they were not already defined.
9649 Remove the code that deletes site-lisp subdirectories from the default
9650 value of EMACSLOADPATH, as it is no longer needed.
9651 (check_windows_init_file): Now external, not static.
9652 Use Vload_path as is, without adding anything, as this function is now
9653 called when Vload_path is already set up.
9655 * w32.h (check_windows_init_file): Add prototype.
9657 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
9658 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
9659 compatibility with Posix platforms.
9660 (main): Move the call to check_windows_init_file to here from
9662 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
9663 any, in the DEFALT argument into the root of the Emacs build or
9664 installation tree, as appropriate.
9666 * callproc.c (init_callproc_1): Call decode_env_path instead of
9667 doing its equivalent by hand.
9668 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
9669 the code that sets Vexec_path run on MS-Windows.
9671 * lread.c (init_lread): Add comments to #ifdef's.
9673 * msdos.c (dos_set_window_size, IT_update_begin)

9681 Now constants, not macros.
9683 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
9685 Remove unnecessary casts involving pointers.
9686 These casts are no longer needed now that we assume C89 or later,

9700 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9701 Remove unnecessary pointer casts.
9702 * alloc.c (record_xmalloc): New function.
9703 * lisp.h (record_xmalloc): New decl.
9704 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9705 more like a function. This is because the pointer cast is not
9706 needed. All uses changed.
9707 * print.c (print_string, print_error_message): Avoid length recalc.
9709 Improve fix for macroexp crash with debugging (Bug#12118).
9710 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9711 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9712 not supposed to be invoked from the garbage collector.

9714 (gc_aset): New function, which is like ASET but can be
9715 used in the garbage collector.

9731 headers (most versions of MinGW w32api don't).
9732 (get_security_info, create_symbolic_link)
9733 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

9744 with addition of handling of symlinks and support for 'lstat'.
9745 If possible, get file's attributes and security information by
9746 handle, not by name. Produce S_IFLNK bit for symlinks, when
9747 called from 'lstat'.
9748 (stat, lstat): New functions, call 'stat_worker'.
9749 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9750 symlinks when the underlying filesystem supports them.
9752 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9754 Fix macroexp crash on Windows with debugging (Bug#12118).
9755 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9756 checking subscripts; problem introduced with the recent
9757 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9758 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9759 since it's used in non-static inline functions now.
9761 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9762 Don't assume buffer size fits in 'int'. Remove unused local.

9782 * composite.c (COMPOSITE_INLINE):
9783 * dispnew.c (DISPEXTERN_INLINE):
9784 * sysdep.c (SYSTIME_INLINE):
9785 Define to EXTERN_INLINE, so that the corresponding functions
9786 are compiled into code.
9787 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9788 (INLINE_HEADER_END): New macros.
9789 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9811 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9813 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9814 This how ASET and AREF are supposed to work, and makes
9815 it easier to think about future improvements. See
9816 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9817 * charset.h (set_charset_attr): New function.

10195 (w32_read_console_input): New inline function, calls either
10196 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
10197 w32_console_unicode_input.
10198 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
10199 (w32_kbd_patch_key, key_event): Use the codepage returned by

10232 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10233 enumeration constants, as PURE and HEAP are too general, and clash
10234 with other headers and sources, such as gmalloc.c and the
10235 MS-Windows system headers. All users changed.
10237 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10239 Revert last save_excursion_save and save_excursion_restore changes.
10240 * alloc.c, editfns.c, marker.c, lisp.h: Revert.
10241 Lots of crashes reported by Chong Yidong <cyd@gnu.org>.
10243 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10245 Fix recently-introduced typos in Windows port.
10246 Reported by Martin Rudalics <rudalics@gmx.at>.

10248 * w32fns.c (syms_of_w32fns): Add missing parenthesis.
10250 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10252 Improve GDB symbol export (Bug#12036).
10253 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10254 arms of an 'if', not using conditional expressions; otherwise GDB
10255 complains about the types in the unevaluated arm when the argument
10256 is an integer literal.
10257 (xgetint): Simplify expression.
10258 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10259 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10260 Zaretskii in <http://bugs.gnu.org/12036#13>.
10261 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10262 needed now that we have gdb_make_enums_visible.
10263 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10264 (enum enum_USE_LSB_TAG):
10265 New enum types, packaging up enums that need to be exported to GDB.
10267 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10269 Utility function to make a list from specified amount of objects.
10270 * lisp.h (enum constype): New datatype.
10271 (listn): New prototype.
10272 * alloc.c (listn): New function.
10273 (Fmemory_use_count, syms_of_alloc): Use it.

10288 Fast save_excursion_save and save_excursion_restore.
10289 * lisp.h (struct Lisp_Excursion): New data type.
10290 (PVEC_EXCURSION): New pseudovector type.
10291 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10292 to deal with it. Adjust comments.
10293 (init_marker, attach_marker): New prototype.
10294 (unchain_marker): Adjust prototype.
10295 * marker.c (attach_marker): Change to global.
10296 (init_marker): New function.
10297 * alloc.c (Fmake_marker, build_marker): Use it.
10298 (build_marker): More easserts.
10299 (mark_object): Handle struct Lisp_Excursion.
10300 * editfns.c (save_excursion_save, save_excursion_restore):

10306 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10307 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10308 emacs.c, as this is a more-suitable home. Had this been done earlier
10309 the fix for 12036 would have avoided some of the problems noted in
10310 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10311 would have been more obvious.
10312 * emacs.c: Do not include <verify.h>; no longer needed.
10313 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
10314 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
10315 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10316 Remove; now done in lisp.h.
10317 * lisp.h (PUBLISH_TO_GDB): New macro.
10318 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
10319 (DATA_SEG_BITS): Use it.
10320 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10321 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10322 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10323 not be usable in #if. This simplifies things.
10325 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10327 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10329 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10331 Simplify export of symbols to GDB (Bug#12036).
10332 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10333 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10334 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10335 Adjust to changes in lisp.h and emacs.c, by using
10336 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10337 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10338 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10339 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10340 instead of gdb_valbits.
10341 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10342 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10343 instead of gdb_array_mark_flag.
10344 (xboolvector): Get size from $->size, not $->header.size.
10345 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10346 (xreload, hook-run, hookpost-run): Remove.
10347 * emacs.c: Include <verify.h>.
10348 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10349 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10351 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10352 (gdb_USE_LSB_TAG): New enum constants.
10353 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10354 Also define these as enum constants, so they're visible to GDB.
10355 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10356 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10357 as constants, so they're visible to GDB.
10358 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10359 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10360 Now enum constants, not macros, so they're visible to GDB.
10361 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10362 more convenient now. All uses changed.
10363 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10364 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10366 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
10368 Explicitly free restriction data that are not needed anymore.
10369 * editfns.c (save_restriction_restore): Free restriction data.
10371 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
10373 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10374 add argument, tune behavior, and adjust all callers.
10376 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10378 Use typedef for EMACS_INT, EMACS_UINT.
10379 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10380 than macros. This simplifies debugging in the usual case, since
10381 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10382 and it allows expressions involving EMACS_INT casts.
10383 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10385 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10387 * nsterm.m (ns_read_socket): Return early if there is a modal
10388 window (Bug#12043).
10390 2012-07-25 Martin Rudalics <rudalics@gmx.at>
10392 * frame.c (Fredirect_frame_focus): In doc-string don't mention
10393 that FOCUS-FRAME can be omitted.

11240 (menu_separator_name_p):
11241 * nsmenu.m (ns_update_menubar):
11242 Prefer memcmp to strncmp when either will do.
11243 * nsterm.m: Include <ftoastr.h>.
11245 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11246 Prefer snprintf to strncpy.
11247 * nsterm.m (ns_term_init):
11248 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11249 * nsterm.m (ns_term_init):
11250 Avoid the need for strncpy, by using build_string or
11251 make_unibyte_string directly. Use dtoastr, not snprintf.
11252 * process.c (Fmake_network_process): Diagnose service names that
11253 are too long, rather than silently truncating them or creating
11254 non-null-terminated names.

11269 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
11270 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
11271 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
11272 where argument type is known to be a Lisp_Cons.
11274 2012-07-10 Tom Tromey <tromey@redhat.com>
11276 * bytecode.c (BYTE_CODE_THREADED): New macro.

11286 (build_pure_c_string): New function, defined as static inline. This
11287 provides a better opportunity to optimize away calls to strlen when
11288 the function is called with compile-time constant argument.
11289 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11290 argument, adjust users accordingly. Use build_pure_c_string where
11292 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
11293 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11294 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
11296 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
11298 Avoid calls to strlen in miscellaneous functions.
11299 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
11300 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
11301 * lread.c (openp): Likewise.
11303 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
11305 Avoid calls to strlen in path processing functions.
11306 * fileio.c (file_name_as_directory): Add comment. Change to add
11307 srclen argument and return the length of result. Adjust users
11309 (directory_file_name): Fix comment. Change to add srclen argument,
11310 swap 1st and 2nd arguments to obey the common convention.
11311 Adjust users accordingly.
11312 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
11314 2012-07-10 Glenn Morris <rgm@gnu.org>

11317 Move PENDING_OUTPUT_COUNT definition to configure.
11319 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
11320 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
11321 * s/gnu.h (DATA_START): Move definitions to configure.
11323 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
11324 We include usg5-4-common.h, which defines them both.
11326 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11327 O_RDONLY already includes it).
11329 Stop ns builds setting the EMACSLOADPATH environment variable.
11330 * nsterm.m (ns_load_path): Rename from ns_init_paths.
11331 Now it does not set EMACSLOADPATH, just returns the load-path string.
11332 * nsterm.h: Update accordingly.
11333 * lread.c [HAVE_NS]: Include nsterm.h.
11334 (init_lread) [HAVE_NS]: Use ns_load_path.
11335 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
11337 2012-07-09 Glenn Morris <rgm@gnu.org>
11339 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
11340 since the included bsd-common.h does so.
11342 Stop ns builds setting the EMACSPATH environment variable.
11343 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
11344 (ns_init_paths): Do not set EMACSPATH.
11345 * nsterm.h (ns_exec_path): Add it.
11346 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
11349 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
11351 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
11353 * process.c (wait_reading_process_output): 'waitchannels' was unset
11354 when read_kbd || !NILP (wait_for_cell); fix this.
11356 Add GCC-style 'const' attribute to functions that can use it.
11357 * character.h (char_resolve_modifier_mask):
11358 * keyboard.h (make_ctrl_char):
11359 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
11360 (init_character_once, next_almost_prime, init_fns, init_image)
11361 (flush_pending_output, init_sound):

11368 Add decls with ATTRIBUTE_CONST.
11370 Minor improvements to make_formatted_string.
11371 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
11372 where int is good enough, as vsprintf returns an int.
11373 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
11375 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11377 Use make_formatted_string to avoid double length calculation.
11378 * lisp.h (make_formatted_string): New prototype.
11379 * alloc.c (make_formatted_string): New function.

11400 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
11402 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11404 Move marker debugging code under MARKER_DEBUG.
11405 * marker.c (MARKER_DEBUG): Move marker debugging code under
11406 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11407 for bootstrap with --enable-checking (~3x slowdown reported
11408 by Juanma Barranquero <lekktu@gmail.com>).
11409 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
11411 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
11413 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
11414 See <http://bugs.gnu.org/11825#29>.
11416 2012-07-08 Eli Zaretskii <eliz@gnu.org>
11418 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11419 has no font, use the frame's font. (Bug#11813)
11420 (display_line): Add commentary about displaying truncation glyphs
11422 (produce_special_glyphs): Move here from term.c.
11424 * term.c (produce_special_glyphs): Move to xdisp.c.
11426 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11429 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11431 * xdisp.c (display_line): Avoid warning about implicit declaration
11434 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11436 * lisp.h: Remove empty conditional.
11438 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11440 * lread.c (load_path_check): Now static.
11442 Fix some minor --with-ns problems found by static checking.
11443 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11444 (x_set_font) [!HAVE_X_WINDOWS]:
11445 * image.c (xpm_load_image) [HAVE_NS]:
11446 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11447 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11448 Remove unused local.
11449 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11450 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11451 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11452 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11453 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11454 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11455 Fix pointer signedness problem.
11456 * xfaces.c (FRAME_X_FONT_TABLE):
11457 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11459 2012-07-07 Glenn Morris <rgm@gnu.org>
11461 * lread.c (load_path_check): New function, split from init_lread.
11462 (init_lread): Reorganize. Motivation:
11463 If EMACSLOADPATH is set, check/warn about that rather than the
11464 defaults, which we are not going to use. Hence we can remove
11465 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11466 Don't warn if site-lisp directories are missing.
11467 If not installed, start from a blank load-path, since
11468 PATH_LOADSEARCH refers to the eventual installation directories.
11470 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11472 Support truncation and continuation glyphs on GUI frames, when
11473 fringes are disabled. (Bug#11832)
11474 * xdisp.c (init_iterator): Get dimensions of truncation and
11475 continuation glyphs even if on GUI frames.
11476 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11477 or both, are absent.
11478 (start_display, move_it_in_display_line_to): Handle the case of a
11479 GUI frame without a fringe to display continuation or truncation
11481 (insert_left_trunc_glyphs): Support GUI frames: make sure
11482 truncation glyphs overwrite enough glyphs from the current line to
11483 have sufficient space in pixels.
11484 (display_line): Support truncation and continuation glyphs on GUI
11485 frames. If some spare pixels are left on the line after inserting
11486 the truncation glyphs, fill that space with a stretch glyph of a
11487 suitably computed width.
11489 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11490 produce_glyphs, to support GUI sessions.
11492 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11494 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11496 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11498 Do not require float-time's arg to fit in time_t (Bug#11825).
11499 This works better on hosts where time_t is unsigned, and where
11500 float-time is applied to the (negative) difference between two times.
11501 * editfns.c (decode_time_components): Last arg is now double *,
11502 not int *, and means to store all the result as a double, without
11503 worrying about whether the seconds part fits in time_t.
11504 All callers changed.
11505 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11506 All callers changed.
11507 (Ffloat_time): Do not fail merely because the specified time falls
11508 outside of time_t range.
11510 2012-07-07 Glenn Morris <rgm@gnu.org>
11512 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11513 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11514 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11516 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11518 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11519 Update dependencies.
11521 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
11523 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

11526 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
11527 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11528 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11529 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11530 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11532 * xfont.c (compare_font_names): Redo to omit the need for casts.
11534 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11536 * xfns.c (Fx_change_window_property): Doc fix.
11537 * w32fns.c (Fx_change_window_property): Doc fix.
11539 * w32fns.c (Fx_window_property): Accept the same arguments as the
11540 X Windows version. Doc fix.
11541 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11543 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11544 Eli Zaretskii <eliz@gnu.org>
11546 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11547 Windows-specific code from nt/config.nt moved here.
11548 Obsolete settings removed.
11550 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11552 * process.c: Avoid unnecessary calls to gettime.
11553 (wait_reading_process_output): Don't get the time of day
11554 when gobbling data immediately and not waiting, as there's no need
11555 for it in that case. This removes a FIXME.
11557 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11559 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11560 is defined (Bug#11768).
11562 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11564 Fix marker debugging code.
11565 * marker.c (byte_char_debug_check): Do not perform the check
11566 if buffer is not multibyte.
11567 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11568 Call byte_char_debug_check with correct arguments.
11570 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11572 Compile marker debugging code only if ENABLE_CHECKING is defined.
11573 * marker.c (byte_char_debug_check, count_markers):
11574 Use only if ENABLE_CHECKING is defined.
11575 (byte_debug_flag): Remove.
11576 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11577 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11579 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11581 Avoid code repetition in marker-related functions.
11582 * marker.c (attach_marker): New function.
11583 (Fset_marker, set_marker_restricted, set_marker_both)

11586 Consistently rename charno to charpos.
11587 (marker_position): Add eassert.
11588 (marker_byte_position): Convert to eassert.
11590 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11592 Simplify list operations in unchain_overlay and unchain_marker.

11602 * composite.c (autocmp_chars): Likewise.
11603 * editfns.c (buildmark): Remove.
11604 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11605 (save_restriction_save): Use build_marker.
11606 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11607 * window.c (save_window_save): Likewise.
11609 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11611 Do not use Fdelete_overlay in delete_all_overlays
11612 to avoid redundant calls to unchain_overlay.

11614 (delete_all_overlays, Fdelete_overlay): Use it.
11615 * minibuf.c (get_minibuffer): Fix comment.
11617 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11619 Port to OpenBSD 5.1 amd64.
11620 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11621 This is needed for OpenBSD, and should be harmless on all BSD systems.
11622 Also, include <sys/sysctl.h>, as it should be available on all
11623 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11624 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11625 use p_pid member, not kp_proc.pid.
11627 2012-07-06 Glenn Morris <rgm@gnu.org>
11629 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11631 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11633 More xmalloc and related cleanup.
11634 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
11635 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

11642 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11644 Omit needless casts involving void * pointers and allocation.
11645 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11646 as the former is more robust if P's type is changed.
11647 Prefer xzalloc to xmalloc + memset 0.
11648 Simplify malloc-or-realloc to realloc.
11649 Don't worry about xmalloc returning a null pointer.
11650 Prefer xstrdup to xmalloc + strcpy.
11651 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11653 * keyboard.c (apply_modifiers_uncached): Prefer local array to

11658 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11659 hscroll is larger than the line width. Fixes long and futile
11660 looping inside extend_face_to_end_of_line (on a TTY) producing
11661 glyphs that are not needed and thrown away.
11663 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11665 * marker.c (set_marker_restricted_both): Simplify by using
11668 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11670 * editfns.c (region_limit): Simplify by using clip_to_bounds.

11679 followed by gtk_box_set_homogeneous (Bug#11768).
11680 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11681 (update_theme_scrollbar_width, xg_create_scroll_bar):
11682 Use gtk_scrollbar_new (Bug#11768).
11683 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11684 (is_box_type): New function (Bug#11768).
11685 (xg_tool_item_stale_p): Call is_box_type.
11686 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11687 with default display (Bug#11768).
11689 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11691 * xdisp.c (window_hscroll_limited): New function.
11692 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11693 coordinates when window's hscroll is set to insanely large
11694 values. (Bug#11857)
11696 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11759 * fileio.c (time_error_value): Check the right error number.
11760 Problem reported by Troels Nielsen in
11761 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11763 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11765 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11766 This should be fixed in a better way; see Eli Zaretskii in
11767 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11768 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11770 * fileio.c (time_error_value): Rename from special_mtime.
11771 The old name's problems were noted by Eli Zaretskii in
11772 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11774 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11775 This variable's comment says Emacs needs at least one GDB-visible
11776 symbol of type enum pvec_type, to work around GDB problems.
11777 The symbol's value doesn't matter.
11779 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11780 that causes compilation to fail on pre-C99 compilers.
11782 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11784 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

11787 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11789 * buffer.c (init_buffer_once): Fix initialization of
11790 headers for buffer_defaults and buffer_local_symbols.
11791 Reported by Juanma Barranquero <lekktu@gmail.com>.
11793 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11795 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11796 * lisp.h (enum pvec_type): Use fewer bits.
11797 (PSEUDOVECTOR_SIZE_BITS): New constant.
11798 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11799 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11800 change in pvec_type.
11801 (PSEUDOVECTOR_TYPEP): New macro.
11802 (TYPED_PSEUDOVECTORP): Use it.
11803 * fns.c (internal_equal): Adapt code to extract pvectype.
11804 * emacs.c (gdb_pvec_type): Update type.
11805 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11806 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11807 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11808 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11809 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11810 abusing vector->header.next.nbytes.
11811 (live_vector_p): Use PVEC_TYPE.
11812 (mark_object): Adapt code to extract pvectype. Use switch.
11814 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11816 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11817 Tighten new eassert a bit.
11819 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11821 Fix compilation with --enable-gcc-warnings and -O1
11822 optimization level.
11823 * doprnt.c (doprnt): Change type of tem to int, initialize
11824 to avoid compiler warning. Add eassert.
11825 * search.c (simple_search): Initialize match_byte to avoid
11826 compiler warning. Add eassert.
11828 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11830 Avoid weird behavior with large horizontal scrolls.
11831 Without this change, for example, large hscroll values would
11832 mess up Emacs's display on Fedora 15 x86, presumably due to
11833 overflows in int calculations in the display code.
11834 Also, if buffers had long lines, Emacs would freeze.
11835 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11836 (set_window_hscroll): New function, containing the old guts of
11837 Fset_window_hscroll. Return the clipped value.
11838 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11839 This avoids the need to check against PTRDIFF_MAX.
11841 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11843 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11845 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11847 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11849 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11850 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11851 since GCC 4.4.6 issues a bogus warning for them.
11853 Fix bugs in file timestamp newness comparisons.
11854 * fileio.c (Ffile_newer_than_file_p):
11855 * lread.c (Fload): Use full timestamp resolution of files,
11856 not just the 1-second resolution, so that files that are only
11857 slightly newer still count as newer.
11858 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11859 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11861 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11863 * fileio.c: Improve handling of file time marker. (Bug#11852)
11864 (special_mtime): New function.
11865 (Finsert_file_contents, Fverify_visited_file_modtime):
11866 Use it to set special mtime values consistently.
11868 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11870 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11871 marker for non-existing file. (Bug#11852)
11873 2012-07-03 Glenn Morris <rgm@gnu.org>
11875 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11876 and did not make it into globals.h).
11878 2012-07-03 Tom Tromey <tromey@redhat.com>
11880 * window.c (Fset_window_margins, Fset_window_fringes)
11881 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

11916 2012-07-03 Glenn Morris <rgm@gnu.org>
11918 * lisp.h (Frandom): Make it visible to C.
11919 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11920 buffer for invisible buffers. (Bug#1229)
11922 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11924 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11925 values which aren't power of 2.
11926 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11927 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11930 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11932 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11934 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11936 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11938 * alloc.c (allocate_vector_block): Remove redundant
11939 calls to mallopt if DOUG_LEA_MALLOC is defined.
11940 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11941 avoid calls to mallopt if zero_vector is returned.
11943 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11945 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11946 is enabled, avoid dereferencing NULL current_sblock if
11949 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11951 Cleanup basic buffer management.
11952 * buffer.h (struct buffer): Change layout to use generic vector
11953 marking code. Fix some comments. Change type of 'clip_changed'
11954 to bitfield. Remove unused #ifndef old.
11955 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11956 (GET_OVERLAYS_AT): Fix indentation.
11957 (for_each_per_buffer_object_at): New macro.
11958 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

11962 struct buffer. Fix comment.
11963 (mark_overlay): New function.
11964 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11965 Lisp area of struct buffer.
11966 (mark_object): Use it. Adjust marking of misc objects
11967 and related comments.
11969 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11971 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11972 wrapper that is not needed because the wrapped code is a no-op (zero
11973 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11974 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11976 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11978 * alloc.c (mark_buffer): Simplify. Remove prototype.
11979 (mark_object): Add comment. Reorganize marking of vector-like
11980 objects. Use CHECK_LIVE for all vector-like objects except buffers
11981 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11982 Avoid redundant calls to mark_vectorlike for bool vectors.
11984 2012-06-30 Glenn Morris <rgm@gnu.org>
11986 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11988 * epaths.in (PATH_SITELOADSEARCH): New.
11989 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11990 This is rather than relying on --enable-locallisppath elements
11991 having "site-lisp" in their names. (Bug#10208#25, 11658)
11993 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11995 * w32proc.c (sys_select): Accept and ignore one more argument.
11997 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11999 * sysselect.h [DOS_NT]: Don't include sys/select.h.
12000 (pselect) [!MS_DOS]: Redirect to sys_select.
12002 * sysdep.c: Don't include dos.h and dosfns.h.
12004 * process.c (sys_select):
12005 * msdos.c (sys_select): Accept one more argument and ignore it.
12007 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
12008 adapt data types and code to that.
12011 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
12012 which clashes with the gnulib function of the same name.
12014 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
12016 * font.c (font_style_to_value, font_style_symbolic)
12017 (font_prop_validate_style): Add type checks for values in
12020 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
12022 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
12025 2012-06-29 Eli Zaretskii <eliz@gnu.org>
12027 * xdisp.c (try_window_id): Undo last change.
12029 * w32.c (getwd): Adjust commentary about startup_dir.
12030 (init_environment): Always call sys_access, even in non-MSVC
12031 builds. Don't chdir to the directory of the Emacs executable.
12032 This undoes code from 1997 which was justified by the need to
12033 "avoid conflicts when removing and renaming directories". But its
12034 downside was that every relative file name was being interpreted
12035 relative to the directory of the Emacs executable, which can never
12036 be TRT. In particular, it broke sys_access when called with
12037 relative file names.
12038 (sys_access): Map GetLastError to errno.
12040 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

12046 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
12049 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
12051 * gnutls.c (emacs_gnutls_handshake):
12052 Add QUIT to make the loop interruptible.
12054 2012-06-29 Glenn Morris <rgm@gnu.org>
12056 * charset.c (init_charset): Make lack of etc/charsets fatal.
12058 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
12060 * editfns.c (region_limit): Fix type mismatch.
12062 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
12064 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
12065 undefined. Convert from xassert to eassert.
12066 * nsmenu.m: Convert from xassert to eassert.
12067 * nsterm.m: Likewise.
12069 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
12071 * editfns.c (region_limit): Clip to narrowing (bug#11770).
12073 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
12075 Avoid integer overflow on scroll-left and scroll-right.
12076 * window.c (HSCROLL_MAX): New macro.
12077 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
12078 overflow when requested scroll falls outside ptrdiff_t range.
12080 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
12082 * window.h (struct window): Change type of 'hscroll',
12083 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
12084 'last_modified' and 'last_overlay_modified' to EMACS_INT.
12085 Adjust users accordingly.
12086 * xdisp.c (try_cursor_movement): Replace type check with eassert.
12087 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
12088 from EMACS_INT to ptrdiff_t.
12089 (make_window): Omit redundant initialization.
12091 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

12108 Fix GLYPH_DEBUG usage assuming that it may be undefined,
12109 adjust comments accordingly.

12172 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
12174 * alloc.c (allocate_string): Remove two redundant calls
12175 to memset, add explicit initialization where appropriate.

12222 * alloc.c: Remove build_string.
12223 * lisp.h: Define build_string as static inline. This provides
12224 a better opportunity to optimize away calls to strlen when the
12225 function is called with compile-time constant argument.
12226 * image.c (imagemagick_error): Convert to build_string.
12227 * w32proc.c (sys_spawnve): Likewise.
12228 * xterm.c (x_term_init): Likewise.
12230 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12232 Use sprintf return value instead of invoking strlen on result.
12233 In the old days this wasn't portable, since some sprintf
12234 implementations returned char *. But they died out years ago and
12235 Emacs already assumes sprintf returns int.
12236 Similarly for float_to_string.
12237 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
12238 * ccl.c (ccl_driver):
12239 * character.c (string_escape_byte8):

12242 * print.c (print_object):
12243 * xdisp.c (message_dolog):
12244 * xfns.c (syms_of_xfns):
12245 Use sprintf or float_to_string result to avoid need to call strlen.
12246 * data.c (Fnumber_to_string):
12247 Use make_unibyte_string, since the string must be ASCII.
12248 * lisp.h, print.c (float_to_string): Now returns int length.
12249 * term.c (produce_glyphless_glyph):
12250 Use sprintf result rather than recomputing it.
12252 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
12253 * Makefile.in (ALL_CFLAGS):
12254 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
12255 * gmalloc.c, regex.c: Include <config.h> unconditionally.
12257 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12259 * dispextern.h (xstrcasecmp): Define to library function
12260 strcasecmp if available.
12261 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
12263 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
12265 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

12276 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
12278 * gtkutil.c (get_utf8_string): Remove redundant assignment.
12279 sprintf already null-terminates its output.
12281 * xfns.c (x_window): Remove redundant cast.
12283 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12285 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
12286 `const char *' to `char *' to avoid compiler warning.
12288 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12290 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12291 instead of truncating it to 63 (admittedly a generous limit).
12293 * process.c: Fix spelling and caps in comments.
12295 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
12297 * emacs.c (setpgrp): Remove definition, unused.

12307 (SYSTIME_H): Add nt/inc/sys/time.h.
12309 * systime.h [WINDOWSNT]: Include sys/time.h.
12311 * s/ms-w32.h (struct timespec): Definition moved from
12312 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
12314 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

12344 Remove unnecessary forward decls.
12346 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12348 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
12349 * lisp.h (WAIT_READING_MAX): New macro.
12350 * dispnew.c (Fsleep_for, sit_for):
12351 * keyboard.c (kbd_buffer_get_event):
12352 * process.c (Faccept_process_output):
12353 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
12354 This improves on the previous patch, which introduced a bug
12355 when time_t is unsigned and as wide as intmax_t.
12356 See <http://bugs.gnu.org/9000#51>.
12358 2012-06-23 Eli Zaretskii <eliz@gnu.org>
12360 * dispnew.c (sit_for, Fsleep_for):
12361 * keyboard.c (kbd_buffer_get_event):
12362 * process.c (Faccept_process_output): Avoid compiler warnings when
12363 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
12365 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
12367 * makefile.w32-in: Update dependencies.
12369 * w32.c (ltime): Add return type and declare static.
12370 (w32_get_internal_run_time): Remove usused variable `time_100ns'.

12374 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
12375 Privately reported by Herbert J. Skuhra.
12376 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
12378 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
12379 not make_lisp_timeval, when the argument is of type EMACS_TIME.
12381 2012-06-23 Eli Zaretskii <eliz@gnu.org>
12383 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
12384 last argument of make_unibyte_string.
12386 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
12387 language ID in the event parameters.
12389 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12390 event.code, not the obscure "character set ID".
12392 2012-06-23 Chong Yidong <cyd@gnu.org>
12394 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
12396 2012-06-23 Eli Zaretskii <eliz@gnu.org>
12398 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

12407 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
12408 in the logic of incrementing and decrementing the value of
12409 use_relocatable_buffers.

12417 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
12418 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
12419 Don't assume EMACS_TIME and struct timeval are the same type.
12421 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12423 Support higher-resolution time stamps (Bug#9000).
12424 The time stamps are only nanosecond-resolution at the C level,
12425 since that's the best that any real-world system supports now.
12426 But they are picosecond-resolution at the Lisp level, as that's
12427 easy, and leaves room for future OS improvements.
12429 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12432 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12433 Don't get current time unless it's needed.
12435 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12436 now provides it if it's absent.
12437 (start_atimer): Port to higher-res time stamps.
12438 Check for time stamp overflow. Don't get current time more
12439 often than is needed.
12441 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12442 Include systime.h, not time.h.
12443 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12445 * dired.c: Include stat-time.h.
12446 (Ffile-attributes): File times now have higher resolution.
12448 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12449 (struct image): Timestamp now has higher resolution.
12451 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12452 has at least microseconds now. All uses removed.
12453 (update_frame, update_single_window, update_window, update_frame_1)
12454 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12455 (duration_to_sec_usec): Remove; no longer needed.
12457 * editfns.c (time_overflow): Now extern.
12458 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12459 (float-time, Fformat_time_string, Fcurrent_time_string)
12460 (Fcurrent_time_zone): Accept and generate higher-resolution
12462 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
12463 (decode_time_components, lisp_seconds_argument): New functions.
12464 (make_time): Now static.
12465 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12466 Report an error if the time is invalid, rather than having the caller
12469 * fileio.c: Include <stat-time.h>
12470 (Fcopy_file): Copy higher-resolution time stamps.
12471 Prefer to set the time stamp via a file descriptor if that works.
12472 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12473 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12474 (Fvisited_file_modtime, Fset_visited_file_modtime):
12475 Support higher-resolution time stamps.
12477 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12479 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12481 * image.c (prepare_image_for_display, clear_image_cache)
12482 (lookup_image): Port to higer-resolution time stamps.
12484 * keyboard.c (start_polling, bind_polling_period):
12485 Check for time stamp overflow.
12486 (read_char, kbd_buffer_get_event, timer_start_idle)
12487 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12488 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12489 Port to higher-resolution time stamps. Do not assume time_t is signed.
12490 (decode_timer): New function. Timers are now vectors of length 9,
12491 not 8, to accommodate the picosecond component.
12492 (timer_check_2): Use it.
12494 * nsterm.m (select_timeout, timeval_subtract): Remove.
12495 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12496 as they're a bit more accurate and handle overflow better.
12497 (ns_select): Change prototype to be compatible with pselect.
12498 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12499 * nsterm.h (ns_select): Adjust prototype.
12501 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12502 us-resolution time stamps.
12503 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12505 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12507 * lisp.h (time_overflow): New decl.
12508 (wait_reading_process_output): First arg is now intmax_t, not int,
12509 to accommodate larger waits.
12511 * process.h (struct Lisp_Process.read_output_delay):
12512 Now counts nanoseconds, not microseconds.
12513 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12515 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12516 (wait_reading_process_output):
12517 Port to ns-resolution time stamps.
12518 (Faccept_process_output, wait_reading_process_output):
12519 Check for time stamp overflow. Do not assume time_t is signed.
12520 (select_wrapper): Remove; we now use pselect.
12521 (Fprocess_attributes): Now generates ns-resolution time stamps.
12523 * sysdep.c: Include utimens.h. Don't include utime.h
12524 or worry about struct utimbuf; gnulib does that for us now.
12525 (gettimeofday): Remove; gnulib provides a substitute.
12526 (make_timeval): New function.
12527 (set_file_times): Now sets ns-resolution time stamps.
12528 New arg FD; all uses changed.
12529 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12530 (system_process_attributes):
12531 Now returns ns-resolution time stamp. All uses changed.
12532 Check for time stamp overflow.
12534 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12535 provides a substitute now.
12537 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12538 since it guarantees struct timespec.
12539 (EMACS_TIME): Now struct timespec, so that we can support
12540 ns-resolution time stamps.
12541 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12542 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12543 (EMACS_USECS): Remove.
12544 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12545 so multiply the arg by 1000 before storing it.
12546 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12548 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12549 Port to ns-resolution time stamps.
12550 (EMACS_TIME_NEG_P): Remove; replaced by....
12551 (EMACS_TIME_SIGN): New macro.
12552 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
12553 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12554 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12555 (make_timeval, make_lisp_time, decode_time_components): New decls.
12556 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12557 that it mishandled time_t overflow. You can't compare by subtracting!
12558 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12559 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12561 * term.c: Include <sys/time.h>.
12562 (timeval_to_Time): New function, for proper overflow wraparound.
12563 (term_mouse_position, term_mouse_click): Use it.
12565 * undo.c (record_first_change): Support higher-resolution time stamps
12566 in the undo buffer.
12567 (Fprimitive_undo): Use them when restoring time stamps.
12569 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12570 (w32_get_internal_run_time):
12571 Port to higher-resolution Emacs time stamps.
12572 (ltime): Now accepts single 64-bit integer, as that's more convenient
12575 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12577 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12578 for compatibility with pselect. Support ns-resolution time stamps.
12580 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12582 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12583 Check for time stamp overflow, and support ns-resolution time stamps.
12585 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12586 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12587 (timeval_subtract): Remove; no longer needed.
12588 (XTflash, XTring_bell, x_wait_for_event):
12589 Port to ns-resolution time stamps. Don't assume time_t is signed.
12591 2012-06-22 Chong Yidong <cyd@gnu.org>
12593 * xdisp.c (x_consider_frame_title): Revert last change.
12595 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12597 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12598 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12599 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12600 staticidx goes up to 1597 out of 1600 = 0x640.)
12602 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12604 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12605 Otherwise, the umask might be mistakenly 0 while handling input signals.
12607 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

13058 * buffer.c (buffer_local_value_1): New function, split from
13059 Fbuffer_local_value; can return Qunbound.
13060 (Fbuffer_local_value): Use it.
13061 (Vmode_line_format): Docstring tweaks.
13063 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
13065 * sysdep.c (system_process_attributes): Improve comment.
13067 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
13069 * keyboard.c: Export real-this-command to Elisp.
13070 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
13071 and DEFVAR it. Update all users.
13073 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
13075 * minibuf.c (Fassoc_string): Remove duplicate declaration.
13077 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
13078 Convert pctcpu and pctmem to Lisp float properly.
13079 Let the compiler fold better, as 100.0/0x8000 is exact.
13081 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
13083 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
13086 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
13088 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
13090 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
13092 For a 'struct window', replace some Lisp_Object fields to
13093 bitfields where appropriate, remove unused fields.
13094 * window.h (struct window): Remove unused 'last_mark_x' and
13095 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
13096 change its type from Lisp_Object to bitfield.
13097 Change type of 'force_start', 'optional_new_start',
13098 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
13099 fields from Lisp_Object to bitfield. Adjust users accordingly.
13101 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13103 Pacify gcc -Wdouble-precision when using Xaw.
13104 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
13105 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
13106 Use 'float' consistently, rather than 'float' in most places
13107 and 'double' in a couple of places.
13109 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13111 * xdisp.c (handle_stop): Detect whether we have overlay strings
13112 loaded by testing it->current.overlay_string_index to be
13113 non-negative, instead of checking whether n_overlay_strings is
13114 positive. (Bug#11587)
13116 2012-05-31 Chong Yidong <cyd@gnu.org>
13118 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
13120 * doc.c (Fsubstitute_command_keys): Doc fix.
13122 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13124 * search.c (search_buffer): Remove calls to
13125 r_alloc_inhibit_buffer_relocation, as it is now called by
13126 maybe_unify_char, which was the cause of relocation of buffer text
13129 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13131 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
13132 for the duration of call to load_charset, to avoid problems with
13133 callers of maybe_unify_char that access buffer text through C
13136 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
13137 decrement the inhibition flag, instead of just setting or
13140 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13142 Remove obsolete '#define static' cruft.
13143 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
13144 This #undef was "temporary" in 2000; it is no longer needed
13145 now that '#define static' has gone away.
13146 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
13147 (gray_bitmap_bits): Remove; no longer needed.
13148 All uses replaced with definiens.
13149 * xterm.c: Include "bitmaps/gray.xbm".
13151 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13153 Clean up __executable_start, monstartup when --enable-profiling.
13154 The following changes affect the code only when profiling.
13155 * dispnew.c (__executable_start): Rename from safe_bcopy.
13156 Define only on platforms that need it.
13157 * emacs.c: Include <sys/gmon.h> when profiling.
13158 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
13159 (__executable_start): Remove decl, since lisp.h does it now.
13160 (safe_bcopy): Remove decl; no longer has that name.
13161 (main): Coalesce #if into single bit of code, for simplicity.
13162 Cast pointers to uintptr_t, since standard libraries want integers
13164 * lisp.h (__executable_start): New decl.
13166 2012-05-31 Glenn Morris <rgm@gnu.org>
13168 * image.c (Fimagemagick_types): Doc fix.
13170 2012-05-30 Jim Meyering <meyering@redhat.com>
13172 * callproc.c (Fcall_process_region): Include directory component
13173 in mkstemp error message (Bug#11586).
13175 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13177 * alloc.c, lisp.h (make_pure_vector): Now static.
13179 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
13181 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
13182 Move to byte-run.el.

13184 * data.c (Fdefalias): Purify definition, except for keymaps.
13185 (Qdefun): Move from eval.c.
13186 * lisp.h (Qdefun): Remove.
13187 * lread.c (read1): Tiny simplification.
13189 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
13191 Do not create empty overlays with the evaporate property (Bug#9642).
13192 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13193 Bug#9642, but explicitly check that the buffer the overlay would
13194 be moved to is live and rearrange lines to make sure that errors
13195 will not put the overlay in an inconsistent state.
13196 (Fdelete_overlay): Cosmetics.
13198 2012-05-28 Eli Zaretskii <eliz@gnu.org>
13200 * w32term.c (my_bring_window_to_top): New function.
13201 (x_raise_frame): Use handle returned by DeferWindowPos, which
13202 could be different from the original one.
13203 Call my_bring_window_to_top instead of my_set_foreground_window.
13206 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
13207 by calling BringWindowToTop.
13209 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

13212 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
13214 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13215 This avoids undefined behavior that might cause the eassert
13216 to not catch an out-of-range value.
13218 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13220 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
13221 Update dependencies.
13223 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13225 * bidi.c (bidi_mirror_char): Fix last change.
13227 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
13229 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
13230 when referring to sectname field in printf format.
13232 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
13234 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
13235 Only r_alloc_inhibit_buffer_relocation needed to be added;
13236 the others were already declared.
13238 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13239 before checking whether it's out of range. Put the check inside
13241 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
13243 2012-05-27 Ken Brown <kbrown@cornell.edu>
13245 * callproc.c (Fcall_process): Restore a line that was accidentally
13246 commented out in the 2011-02-13 change (bug#11547).
13248 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13250 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13251 defined on ralloc.c.
13253 * buffer.c [REL_ALLOC]: Remove prototypes of
13254 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
13255 they are now on lisp.h.
13257 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13259 * search.c (search_buffer): Use it to inhibit relocation of buffer
13260 text while re_search_2 is doing its job, because re_search_2 is
13261 passed C pointers to buffer text. (Bug#11519)
13263 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13264 Update value to 24.
13266 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13267 state after an additional call to move_it_in_display_line_to, keep
13268 the values of it->max_ascent and it->max_descent found for the
13270 (pos_visible_p): Revert the comparison against bottom_y to what it
13271 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13274 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13276 Fix coding-related core dumps with gcc -ftrapv.
13277 The code was computing A - B, where A and B are pointers, and B is
13278 random garbage. This can lead to core dumps on platforms that
13279 have special pointer registers, and it also leads to core dumps on
13280 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13281 A - B only when B is initialized properly.
13282 * coding.c (coding_set_source, coding_set_destination): Return void.
13283 (coding_change_source, coding_change_destinations): New functions,
13284 with the old behaviors of coding_set_source and coding_set_destination.
13285 All callers that need an offset changed to use these new functions.
13287 2012-05-26 Glenn Morris <rgm@gnu.org>
13289 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
13291 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13293 Extend mouse support on W32 text-mode console.
13294 * xdisp.c (draw_row_with_mouse_face):
13295 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13297 * w32console.c: Include window.h.
13298 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13300 (initialize_w32_display): Initialize mouse-highlight data.
13302 * w32inevt.c: Include termchar.h and window.h.
13303 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13304 moves, call note_mouse_highlight. If help_echo changed, call
13305 gen_help_event to produce help-echo message in the echo area.
13306 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13309 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13311 * lread.c (read1): Simplify slightly to avoid an overflow warning
13312 with GCC 4.7.0 on x86-64.
13314 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13316 * bidi.c (bidi_mirror_char): Revert last change: an int is
13317 definitely wide enough here.
13319 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13321 Fix integer width and related bugs (Bug#9874).
13322 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
13323 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
13324 (string_bytes, check_sblock, allocate_string_data):
13325 (compact_small_strings, Fmake_bool_vector, make_string)
13326 (make_unibyte_string, make_multibyte_string)
13327 (make_string_from_bytes, make_specified_string)
13328 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
13329 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
13331 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13332 (allocate_pseudovector):
13333 Use int, not EMACS_INT, where int is wide enough.
13334 (inhibit_garbage_collection, Fgarbage_collect):
13335 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13336 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13337 int might not be wide enough.
13338 (bidi_cache_search, bidi_cache_find, bidi_init_it)
13339 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
13340 (bidi_at_paragraph_end, bidi_find_paragraph_start)
13341 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
13342 (bidi_level_of_next_char, bidi_move_to_visually_next):
13343 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13344 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
13345 (Fkill_buffer, Fset_buffer_major_mode)
13346 (advance_to_char_boundary, Fbuffer_swap_text)
13347 (Fset_buffer_multibyte, overlays_at, overlays_in)
13348 (overlay_touches_p, struct sortvec, record_overlay_string)
13349 (overlay_strings, recenter_overlay_lists)
13350 (adjust_overlays_for_insert, adjust_overlays_for_delete)
13351 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
13352 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
13353 (Foverlay_recenter, last_overlay_modification_hooks_used)
13354 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13355 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13356 (validate_region): Omit unnecessary test for b <= e,
13357 since that's guaranteed by the previous test.
13358 (adjust_overlays_for_delete): Avoid pos + length overflow.
13359 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13360 (report_overlay_modification):
13361 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13362 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13363 Omit pointer cast, which isn't needed anyway, and doesn't work
13364 after the EMACS_INT -> ptrdiff_t change.
13365 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13366 * buffer.h: Adjust decls to match defn changes elsewhere.
13367 (struct buffer_text, struct buffer):
13368 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13369 Use EMACS_INT, not int, where int might not be wide enough.
13370 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13371 not int, to avoid needless 32-bit limit on 64-bit hosts.
13372 (exec_byte_code): Use tighter memory-full test, one that checks
13373 for alloca overflow. Don't compute the address of the object just
13374 before an array, as that's not portable. Use EMACS_INT, not
13375 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13376 * callint.c (Fcall_interactively):
13377 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13378 * callproc.c (call_process_kill, Fcall_process):
13379 Don't assume pid_t fits into an Emacs fixnum.
13380 (call_process_cleanup, Fcall_process, child_setup):
13381 Don't assume pid_t fits into int.
13382 (call_process_cleanup, Fcall_process, delete_temp_file)
13383 (Fcall_process_region):
13384 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13385 (Fcall_process): Simplify handling of volatile integers.
13386 Use int, not EMACS_INT, where int will do.
13387 * casefiddle.c (casify_object, casify_region, operate_on_word)
13388 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13389 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13390 (casify_object): Avoid integer overflow when overallocating buffer.
13391 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13392 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13393 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13394 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13395 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13396 integers are now checked earlier. All uses replaced with XINT.
13398 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13399 For CCL_MapSingle, check that content and value are in int range.
13400 (ccl_driver, Fregister_code_conversion_map):
13401 Check that Vcode_version_map_vector is a vector.
13402 (resolve_symbol_ccl_program): Check that vector header is in range.
13403 Always copy the vector, so that we can check its contents reliably
13404 now rather than having to recheck each instruction as it's being
13405 executed. Check that vector words fit in 'int'.
13406 (ccl_get_compiled_code, Fregister_ccl_program)
13407 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13408 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13409 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13410 contents are in range.
13411 (Fccl_execute_on_string): Check that status is in range.
13412 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13413 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13414 Accept and return EMACS_INT, not int, because callers can pass values
13415 out of 'int' range.
13416 (c_string_width, strwidth, lisp_string_width, chars_in_text)
13417 (multibyte_chars_in_text, parse_str_as_multibyte)
13418 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
13419 (str_as_unibyte, str_to_unibyte, string_count_byte8)
13420 (string_escape_byte8, Fget_byte):
13421 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13422 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13423 avoid mishandling large integers.
13424 * character.h: Adjust decls to match defn changes elsewhere.
13425 * charset.c (load_charset_map_from_file, find_charsets_in_text)
13426 (Ffind_charset_region):
13427 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13428 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
13429 (load_charset_map_from_vector, Fdefine_charset_internal):
13430 Don't assume fixnum fits in int.
13431 (load_charset_map_from_vector, Fmap_charset_chars):
13432 Remove now-unnecessary CHECK_NATNUMs.
13433 (Fdefine_charset_internal): Check ranges here, more carefully.
13434 Don't rely on undefined behavior with signed left shift overflow.
13435 Don't assume unsigned int fits into fixnum, or that fixnum fits
13436 into unsigned int. Don't require max_code to be a valid fixnum;
13437 that's not true for gb10830 4-byte on a 32-bit host. Allow
13438 invalid_code to be a cons, for the same reason. Require code_offset
13439 to be a character. Avoid int overflow if max_char is close
13441 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13442 this is intended anyway and avoids some undefined behavior.
13443 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13444 INDEX_TO_CODE_POINT, as that's what it expects.
13445 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13446 * charset.h (DECODE_CHAR): Return int, not unsigned;
13447 this is what was intended anyway, and it avoids undefined behavior.
13448 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13449 integer-overflow issues.
13450 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13451 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13452 where the argument is EMACS_INT, and this behavior is not intended.
13453 * chartab.c (Fmake_char_table, Fset_char_table_range)
13454 (uniprop_get_decoder, uniprop_get_encoder):
13455 Don't assume fixnum fits in int.
13456 * cmds.c (move_point): New function, that does the gist of
13457 Fforward_char and Fbackward_char, but does so while checking
13458 for integer overflow more accurately.
13459 (Fforward_char, Fbackward_char): Use it.
13460 (Fforward_line, Fend_of_line, internal_self_insert)
13461 (internal_self_insert):
13462 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13463 Fix a FIXME, by checking for integer overflow when calculating
13464 target_clm and actual_clm.
13465 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
13466 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

14145 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
14148 This directory predates autoconf and is no longer needed nowadays.
14149 Move its few remaining bits of functionality to where they're needed.
14150 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
14151 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
14152 * m/template.h: Remove.
14153 * Makefile.in (M_FILE): Remove. All uses removed.
14154 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
14155 * lisp.h (USE_LSB_TAG):
14156 * mem-limits.h (EXCEEDS_LISP_PTR):
14157 Use VAL_MAX, not VALBITS, in #if.
14158 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
14159 (EMACS_UINT): Define unconditionally now.
14160 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
14161 (BITS_PER_EMACS_INT): New constants, replacing
14162 what used to be in config.h, but not useful in #if.
14163 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
14164 define them any more.
14165 (VAL_MAX): New macro.
14167 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
14168 BITS_PER_EMACS_INT, in #if.
14169 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
14170 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
14171 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
14172 * s/ms-w32.h (DATA_START):
14173 Move here from removed file m/intel386.h.
14174 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
14175 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
14177 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
14179 Assume C89 or later.
14180 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
14181 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
14183 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
14184 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
14185 * textprop.c, tparam.c (NULL): Remove.
14186 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
14187 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
14188 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
14189 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
14190 * xterm.c (input_signal_count): Assume volatile works.
14192 2012-05-21 Ken Brown <kbrown@cornell.edu>
14194 * xgselect.c (xg_select): Fix first argument in call to 'select'
14197 2012-05-20 Ken Brown <kbrown@cornell.edu>
14199 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
14200 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
14202 2012-05-19 Ken Brown <kbrown@cornell.edu>
14204 * xfns.c (x_in_use): Remove `static' qualifier.
14205 * xterm.h (x_in_use): Declare.
14206 * xgselect.c: Include xterm.h.
14207 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
14208 and `display_arg' (bug#9754).
14210 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
14212 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
14214 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
14215 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
14217 2012-05-18 Eli Zaretskii <eliz@gnu.org>
14219 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
14221 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
14222 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
14224 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
14225 reference to image_cache->refcount.
14226 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
14228 2012-05-17 Juri Linkov <juri@jurta.org>
14230 * search.c (Fword_search_regexp, Fword_search_backward)
14231 (Fword_search_forward, Fword_search_backward_lax)
14232 (Fword_search_forward_lax): Move functions to isearch.el
14233 (bug#10145, bug#11381).
14235 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
14237 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
14239 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
14241 * lread.c (init_obarray): Declare Qt and Qnil as special.
14243 2012-05-14 Glenn Morris <rgm@gnu.org>
14245 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
14246 Put "libexec" before "bin", for the sake of init_callproc_1.
14248 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14250 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
14252 * unexaix.c: Port to more-recent AIX compilers.
14253 (report_error, report_error_1, make_hdr, copy_sym)
14254 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
14255 Make arguments const char *, not char *, to avoid violations of C
14256 standard and to fix some AIX warnings reported by Gilles Pion.
14258 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14260 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
14261 already have overlays loaded.
14262 (handle_single_display_spec): Before returning without displaying
14263 fringe bitmap, synchronize the bidi iterator with the main display
14264 iterator, by calling iterate_out_of_display_property.
14265 (iterate_out_of_display_property): Detect buffer iteration by
14266 testing that it->string is a Lisp string.
14267 (get_next_display_element): When the current object is exhausted,
14268 and there's something on it->stack, call set_iterator_to_next to
14269 proceed with what's on the stack, instead of returning zero.
14270 (set_iterator_to_next): If called at the end of a Lisp string,
14271 proceed to consider_string_end without incrementing string
14272 position. Don't increment display vector index past the end of
14273 the display vector. (Bug#11417)
14274 (pos_visible_p): Don't report a position visible when move_it_to
14275 stopped at the last line of window, which happens to be scanned
14276 backwards by the bidi iteration. (Bug#11464)
14278 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14280 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14281 and right-margin display specs even if the spec is invalid or we
14282 are on a TTY, and thus unable to display on the fringes.
14283 That's because the text with the property will not be displayed anyway,
14284 so we need to signal to the caller that this is a "replacing"
14285 display spec. This fixes display when the spec is invalid or we
14288 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14290 * unexaix.c (make_hdr): Fix typo in prototype.
14291 This bug broke the build on AIX. Problem reported by Gilles Pion.
14293 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
14295 * keyboard.c (kbd_buffer_get_event): Read special events also in
14296 batch mode. (Bug#11415)
14298 2012-05-12 Glenn Morris <rgm@gnu.org>
14300 * ns.mk: Update for ns_appbindir no longer having trailing "/".
14302 2012-05-12 Eli Zaretskii <eliz@gnu.org>
14304 * lisp.mk (lisp): Add newcomment.elc.
14306 2012-05-12 Glenn Morris <rgm@gnu.org>
14308 * Makefile.in (MKDIR_P): New, set by configure.
14309 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
14311 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
14313 Remove unused function hourglass_started.
14314 * dispextern.h (hourglass_started):
14315 * w32fns.c (hourglass_started):
14316 * xdisp.c (hourglass_started): Remove.
14318 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
14320 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
14321 Update dependencies.
14323 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14325 * xgselect.c (xg_select): Put maxfds+1 into a var.
14326 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14328 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14330 2012-05-10 Dave Abrahams <dave@boostpro.com>
14332 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14333 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14335 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14337 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14338 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14339 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14340 Initialize xd_registered_buses.
14342 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14344 Untag more efficiently if USE_LSB_TAG.
14345 This is based on a proposal by YAMAMOTO Mitsuharu in
14346 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14347 For an admittedly artificial (nth 8000 longlist) benchmark on
14348 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14349 Emacs's overall text size by 1%.
14350 * lisp.h (XUNTAG): New macro.
14351 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14352 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14353 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14354 * eval.c (Fautoload):
14355 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14356 * frame.h (XFRAME): Use XUNTAG.
14358 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14359 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14360 Remove unportable assumptions about print widths of types like
14362 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14363 intptr_t when converting between pointer and integer, to avoid GCC
14364 warnings about wrong width.
14366 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14368 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14369 stack for each reader_thread, instead of defaulting to 8MB
14370 determined by the linker. This avoids failures in creating
14371 subprocesses on Windows 7, see the discussion in this thread:
14372 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14374 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14376 Fix up display of the *Minibuf-0* buffer in the mini window.
14377 * keyboard.c (read_char): Don't clear the echo area if there's no
14379 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14380 contents of *Minibuf-0*) if there's no message displayed in its stead.
14382 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14384 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14387 2012-05-06 Chong Yidong <cyd@gnu.org>
14389 * lisp.mk (lisp): Update.
14391 2012-05-05 Jim Meyering <meyering@redhat.com>
14393 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14395 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14397 * data.c (PUT_ERROR): New macro.
14398 (syms_of_data): Use it. Add new error type `user-error'.
14399 * undo.c (user_error): New function.
14400 (Fprimitive_undo): Use it.
14401 * print.c (print_error_message): Adjust print style for `user-error'.
14402 * keyboard.c (user_error): New function.
14403 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14405 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14407 Do not limit current-time-string to years 1000..9999.
14408 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14409 (Fcurrent_time_string): Support any year that is supported by the
14410 underlying localtime representation. Don't use asctime, as it
14411 has undefined behavior for years outside the range -999..9999.
14413 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14415 Fix race conditions involving setenv, gmtime, localtime, asctime.
14416 Without this fix, interrupts could mess up code that uses these
14417 nonreentrant functions, since setting TZ invalidates existing
14418 tm_zone or tzname values, and since most of these functions return
14419 pointers to static storage.
14420 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14421 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14422 Grow the critical sections to include not just invoking
14423 localtime/gmtime, but also accessing these functions' results
14424 including their tm_zone values if any, and any related TZ setting.
14425 (format_time_string): Last arg is now struct tm *, not struct tm **,
14426 so that the struct tm is saved in the critical section.
14427 All callers changed. Simplify allocation of initial buffer, partly
14428 motivated by the fact that memory allocation needs to be outside
14429 the critical section.
14431 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14433 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14434 with RESET_INTERVAL.
14436 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14437 Remove duplicated buffer name initialization.
14439 2012-05-02 Jim Meyering <jim@meyering.net>
14441 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14443 * xfns.c (x_window): Use xstrdup (Bug#11375).
14445 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14447 * xdisp.c (pos_visible_p): If already at a newline from the
14448 display string before the 'while' loop, don't walk back the glyphs
14449 from it3.glyph_row. Solves assertion violation when the display
14450 string begins with a newline (egg.el). (Bug#11367)
14452 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14454 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14457 2012-05-01 Glenn Morris <rgm@gnu.org>
14459 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14460 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14461 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14462 All were removed before 23.1.
14464 * dispnew.c: Remove HAVE_LIBNCURSES test;
14465 it is always true on relevant platforms.
14467 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14468 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14470 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14472 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14474 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14475 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14478 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14480 Do not avoid creating empty evaporating overlays (Bug#9642).
14481 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14482 That is, do not delete an evaporating overlay if it becomes
14483 empty after its bounds are adjusted to fit within its buffer.
14484 This fix caused other problems, and I'm reverting it until we get
14485 to the bottom of them.
14487 2012-04-27 Chong Yidong <cyd@gnu.org>
14489 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14491 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14493 * xdisp.c (pos_visible_p): If the window start position is beyond
14494 ZV, start the display from buffer beginning. Prevents assertion
14495 violation in init_iterator when the minibuffer window is scrolled
14496 via the scroll bar.
14498 * window.c (window_scroll_pixel_based): Likewise.
14500 2012-04-27 Chong Yidong <cyd@gnu.org>
14502 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14504 2012-04-27 Glenn Morris <rgm@gnu.org>
14506 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14507 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14509 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14511 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14512 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14514 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14516 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14517 display element, check also the underlying string or buffer
14518 character. (Bug#11341)
14520 * w32menu.c: Include w32heap.h.
14521 (add_menu_item): If the call to AppendMenuW (via
14522 unicode_append_menu) fails, disable Unicode menus only if we are
14523 running on Windows 9X/Me.
14525 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14527 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14528 (xgetint): Add missing shift for LSB tags.
14530 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14532 * keyboard.c (read_char): Don't wipe echo area for select window
14533 events: These might get delayed via `mouse-autoselect-window'
14536 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14538 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14539 manipulation of :loaded-from data.
14541 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14543 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14544 now a cons (bug#11311).
14546 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14548 Do not create empty overlays with the evaporate property (Bug#9642).
14549 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14550 if it becomes empty after its bounds are adjusted to fit within
14551 its buffer. Without this fix, in a nonempty buffer (let ((o
14552 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14553 yields an empty overlay that has the evaporate property, which is
14554 not supposed to happen.
14556 Fix minor GTK3 problems found by static checking.
14557 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14558 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14559 (struct _EmacsFixedClass, emacs_fixed_get_type):
14560 Move decls here from emacsgtkfixed.h, since they needn't be public.
14561 (emacs_fixed_get_type): Now static.
14562 (emacs_fixed_class_init): Omit unused local.
14563 (emacs_fixed_child_type): Remove; unused.
14564 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14565 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14566 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14567 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14568 (EMACS_FIXED_GET_CLASS): Remove; unused.
14569 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14571 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14572 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14574 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14576 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14577 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14578 (__malloc_size_t, __malloc_ptrdiff_t):

14669 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14671 * sysdep.c [__FreeBSD__]: Minor cleanups.
14672 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14673 Use Emacs indenting style more consistently. Avoid some casts.

14755 New extern decls, to avoid calling undeclared functions.
14756 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14757 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14758 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14759 (NEED_MEM_INSERT): New macro.
14760 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14761 Remove one incorrect comment and fix another.

14776 Remove decls. This fixes an "It stinks!".
14778 * alloc.c (which_symbols): Fix alignment issue / type clash.
14780 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14782 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

14797 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14798 * s/netbsd.h, s/sol2-6.h:
14799 Remove definition of GC_MARK_STACK, since the default now works.
14800 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14801 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's

14803 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14805 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14828 2012-04-11 Daniel Colascione <dancol@dancol.org>
14830 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14831 against is gone. It's better to use vfork now so that when Cygwin
14832 gains a new, working vfork, we use it automatically (bug#10398).
14834 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14855 being loaded (bug#10424).
14857 2012-04-09 Glenn Morris <rgm@gnu.org>
14859 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

14877 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14878 attempts per process (connection).
14880 2012-04-09 Chong Yidong <cyd@gnu.org>
14882 * eval.c (Fuser_variable_p, user_variable_p_eh)

14887 * minibuf.c (Fread_variable): Callers changed.
14889 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14891 * xdisp.c (set_cursor_from_row): If the display string appears in
14892 the buffer at position that is closer to point than the position
14893 after the display string, display the cursor on the first glyph of
14894 the display string. Fixes cursor display when a 'display' text
14895 property immediately follows invisible text. (Bug#11094)
14897 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14899 composite.c: use 'double' consistently
14900 * composite.c (get_composition_id): Use 'double' consistently
14901 instead of converting 'float' to 'double' and vice versa; this is
14902 easier to understand and avoids a GCC warning.
14904 2012-04-09 Glenn Morris <rgm@gnu.org>
14906 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14907 preparation for dumping it with emacs. (Bug#4789)

14929 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14930 (mark_memory): Mark Lisp_Objects only if pointers might hide in

14945 (GLOBAL_SOURCES): Add xml.c.
14946 ($(BLD)/xml.$(O)): New dependency list.
14948 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14949 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14950 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14951 [!WINDOWSNT]: New macros.
14952 (init_libxml2_functions, libxml2_loaded_p): New functions.
14953 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14954 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14955 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14956 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14958 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14959 Call init_libxml2_functions before calling libxml2 functions.
14960 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14962 * emacs.c: Don't include libxml/parser.h.
14963 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14964 xmlCleanupParser directly.
14966 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14968 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14970 * indent.c (Fvertical_motion): If there is a display string at
14971 point, use it.vpos to compute how many lines to backtrack after
14972 move_it_to point. (Bug#11133)
14974 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14976 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14977 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14978 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14979 macros related to unification of CJK characters. For the details,
14980 see the discussion following the message here:
14981 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

14994 * w32menu.c (is_simple_dialog): Properly check lisp types.
14997 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14999 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
15000 position we get to after a call to move_it_to fails the
15001 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
15002 only if we wind up in a string from display property. (Bug#11063)
15004 * window.c (Fdelete_other_windows_internal): Invalidate the row
15005 and column information about mouse highlight, so that redisplay
15006 restores it after reallocating the glyph matrices. (Bug#7464)
15008 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
15009 string comes from a `display' text property, use the buffer
15010 position of that property as if we actually saw that position in
15012 (move_it_by_lines): Remove the assertion that
15013 "it->current_x == 0 && it->hpos == 0" which can be legitimately
15014 violated when there's a before-string at the beginning of a line.
15017 2012-03-30 Eli Zaretskii <eliz@gnu.org>
15019 * xdisp.c (append_space_for_newline): If the default face was
15020 remapped, use the remapped face for the appended newline.
15021 (extend_face_to_end_of_line): Use the remapped default face for
15022 extending the face to the end of the line.
15023 (display_line): Call extend_face_to_end_of_line when the default
15024 face was remapped. (Bug#11068)
15026 2012-03-29 Eli Zaretskii <eliz@gnu.org>
15028 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

15034 2012-03-27 Glenn Morris <rgm@gnu.org>
15036 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
15039 2012-03-26 Kenichi Handa <handa@m17n.org>

15046 * keyboard.c (Vselection_inhibit_update_commands): New variable.
15047 (command_loop_1): Use it; inhibit selection update for
15048 handle-select-window too (Bug#8996).
15050 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
15052 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
15054 2012-03-25 Kenichi Handa <handa@m17n.org>
15056 * dispextern.h (struct glyph): Change the bit length of
15057 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
15059 2012-03-24 Eli Zaretskii <eliz@gnu.org>
15061 * s/ms-w32.h (tzname): Include time.h before redirecting to
15062 _tzname. Fixes the MSVC build. (Bug#9960)
15064 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
15066 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
15069 * xterm.c (XTread_socket): Only modify handling_signal if
15070 !SYNC_INPUT. (Bug#11080)
15072 2012-03-23 Eli Zaretskii <eliz@gnu.org>
15074 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
15075 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
15076 when fetching a multibyte character consumes more bytes than
15077 CHAR_BYTES returns, due to unification of CJK characters in
15078 string_char. (Bug#11073)
15080 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
15082 * process.c (wait_reading_process_output): Handle pty disconnect
15083 by refraining from sending oneself a SIGCHLD (bug#10933).

15091 (handle_face_prop): Use default face for prefix strings (Bug#4281).
15092 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
15094 2012-03-21 Chong Yidong <cyd@gnu.org>

15112 it fit in a valid range (Bug#11003).
15114 2012-03-18 Eli Zaretskii <eliz@gnu.org>
15116 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
15117 that is not from display property, accept the row as a "cursor
15118 row" if one of the string's character has a non-nil `cursor'
15119 property. Fixes cursor positioning when there are newlines in
15120 overlay strings, e.g. in icomplete.el. (Bug#11035)
15122 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
15124 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
15126 2012-03-12 Chong Yidong <cyd@gnu.org>
15128 * eval.c (inhibit_lisp_code): Rename from
15129 inhibit_window_configuration_change_hook; move from window.c.
15131 * xfns.c (unwind_create_frame_1, Fx_create_frame):
15132 * window.c (run_window_configuration_change_hook)
15133 (syms_of_window): Callers changed.

15153 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
15156 2012-03-03 Glenn Morris <rgm@gnu.org>
15158 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
15160 2012-03-02 Eli Zaretskii <eliz@gnu.org>
15162 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
15163 position past the first glyph_row that ends at ZV. (Bug#10902)
15164 (redisplay_window, next_element_from_string): Fix typos in
15166 (redisplay_window): Pass to move_it_vertically the margin in
15167 pixels, not in screen lines.
15169 2012-03-02 Glenn Morris <rgm@gnu.org>
15171 * buffer.c (buffer-list-update-hook): Doc fix.
15173 2012-02-29 Eli Zaretskii <eliz@gnu.org>
15175 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
15176 push_it before setting up the iterator for the first overlay
15177 string, even if we have an empty string loaded.
15178 (next_overlay_string): If there's an empty string on the iterator
15179 stack, pop the stack. (Bug#10903)
15181 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
15183 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15184 Suggested by Stefan Monnier in
15185 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15186 * alloc.c (widen_to_Lisp_Object): New static function.
15187 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15188 and widening them to Lisp_Objects. This would work even if
15189 USE_LSB_TAG is defined and wide integers are used, which might
15190 happen in a future version of Emacs.
15192 2012-02-25 Chong Yidong <cyd@gnu.org>
15194 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
15197 * xselect.c (Fx_selection_exists_p): Doc fix.
15198 (x_clipboard_manager_save_all): Print an informative message
15199 before saving to clipboard manager.
15201 2012-02-24 Chong Yidong <cyd@gnu.org>
15203 * keyboard.c (process_special_events): Handle all X selection
15204 requests in kbd_buffer, not just the next one (Bug#8869).
15206 2012-02-23 Chong Yidong <cyd@gnu.org>
15208 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
15209 call when setting menu-bar-lines and tool-bar-lines parameters.
15210 (unwind_create_frame_1): New helper function.
15212 * window.c (inhibit_window_configuration_change_hook): New var.
15213 (run_window_configuration_change_hook): Obey it.

15223 * fileio.c (Vfile_name_handler_alist): Doc fix.
15225 * buffer.c (Fget_file_buffer): Protect against invalid file
15226 handler return value.
15228 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
15230 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
15231 when computing $valmask.
15233 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15234 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15235 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15236 It's useless in that case, and it can cause problems on hosts
15237 that allocate halves of EMACS_INT values separately.
15238 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15239 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15240 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15241 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15242 it avoids undefined behavior on hosts where shifting right by more
15243 than the word width has undefined behavior.
15245 2012-02-19 Chong Yidong <cyd@gnu.org>
15247 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15248 (Funhandled_file_name_directory, Ffile_name_as_directory)
15249 (Fdirectory_file_name, Fexpand_file_name)
15250 (Fsubstitute_in_file_name): Protect against invalid file handler
15251 return values (Bug#10845).
15253 2012-02-18 Eli Zaretskii <eliz@gnu.org>
15255 * .gdbinit (pitx): Fix incorrect references to fields of the

15265 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
15267 2012-02-15 Chong Yidong <cyd@gnu.org>
15269 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
15270 marked as special. Also, starting docstrings with * is obsolete.

15285 2012-02-12 Chong Yidong <cyd@gnu.org>
15287 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
15288 as that creates a dangerous corner case.
15290 * window.c (Fdelete_window_internal): Invalidate the mouse
15291 highlight (Bug#9904).
15293 2012-02-12 Glenn Morris <rgm@gnu.org>

15298 * nsselect.m (Fx_own_selection_internal)
15299 (Fx_disown_selection_internal, Fx_selection_exists_p)
15300 (Fx_selection_owner_p, Fx_get_selection_internal):
15301 Sync docs and argument specs with the xselect.c versions.
15303 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

15323 2012-02-07 Chong Yidong <cyd@gnu.org>
15325 * buffer.c (Fbuffer_local_variables)
15326 (buffer_lisp_local_variables): Handle unbound vars correctly;
15327 don't let Qunbound leak into Lisp.
15329 2012-02-07 Glenn Morris <rgm@gnu.org>
15331 * image.c (Fimagemagick_types): Doc fix.
15333 * image.c (imagemagick-render-type): Change it from a lisp object
15334 to an integer. Move the doc here from the lisp manual.

15354 Include --enable-checking, if specified, in the return value.
15356 2012-02-04 Martin Rudalics <rudalics@gmx.at>
15358 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols

15363 * keyboard.c (adjust_point_for_property): Don't position point
15364 before BEGV. (Bug#10696)
15366 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
15368 Handle overflow when computing char display width (Bug#9496).
15369 * character.c (char_width): Return EMACS_INT, not int.
15370 (char_width, c_string_width): Check for overflow when
15371 computing the width; this is possible now that individual
15372 characters can have unbounded width. Problem introduced
15373 by merge from Emacs 23 on 2012-01-19.
15375 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

15397 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
15399 (x_produce_glyphs): If the component of a composition is a null
15400 string, set it->pixel_width to 1 to avoid zero-width glyph.
15402 2012-02-01 Eli Zaretskii <eliz@gnu.org>
15404 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15405 first 2 arguments are identical. This makes inserting large
15406 output from a subprocess an order of magnitude faster on
15407 MS-Windows, where all sbrk'ed memory is always contiguous.
15409 2012-01-31 Glenn Morris <rgm@gnu.org>

15492 2012-01-11 Glenn Morris <rgm@gnu.org>
15494 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

15499 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
15501 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
15502 Update template values to be closer to their typical values these days.
15504 2012-01-09 Eli Zaretskii <eliz@gnu.org>

16022 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
16023 Otherwise, valgrind does not work on some platforms.
16024 Problem reported by Andreas Schwab in
16025 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
16026 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
16027 is set, removing the need for VIRT_ADDRESS_VARIES.
16028 (PURE_P): Use a more-efficient implementation that needs just one
16029 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
16030 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
16031 to 4 (xorl, subq, cmpq, setbe).
16032 * alloc.c (pure): Always extern now, since that's the
16033 VIRT_ADDR_VARIES behavior.
16034 (PURE_POINTER_P): Use a single comparison, not two, for
16035 consistency with the new puresize.h.
16036 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
16037 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

16045 behave as if the cursor position were at the window margin.
16047 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
16048 and the cursor position is out of bounds, behave as if the cursor
16049 position were at the window margin. (Bug#10075)
16051 2011-11-18 Chong Yidong <cyd@gnu.org>
16053 * window.c (Fwindow_combination_limit): Make first argument

16074 * xdisp.c (row_hash): New function, body extracted from
16075 compute_line_metrics.
16076 (compute_line_metrics): Call row_hash, instead of computing the
16079 * dispnew.c (verify_row_hash): Call row_hash for computing the
16080 hash code of a row, instead of duplicating code from xdisp.c.
16082 * dispextern.h (row_hash): Add prototype.
16084 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

16120 2011-11-14 Eli Zaretskii <eliz@gnu.org>
16122 * xdisp.c (display_line): Move the call to
16123 highlight_trailing_whitespace before the call to
16124 compute_line_metrics, since the latter needs to see the final
16125 faces of all the glyphs to compute ROW's hash value.
16126 Fixes assertion violations in row_equal_p. (Bug#10035)
16128 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
16130 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
16131 just return (bug#10044).
16133 2011-11-12 Eli Zaretskii <eliz@gnu.org>
16135 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
16136 with user-defined heap size. Bump the default size of the temacs

16140 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
16141 current_matrix and desired_matrix. (Bug#9990)
16142 (verify_row_hash) [XASSERTS]: New function.

16189 Avoid some portability problems by eschewing 'extern inline' functions.
16190 The trivial performance wins aren't worth the portability hassles; see
16191 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
16193 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

16267 (window_box_width, window_box_left, window_box_left_offset)
16268 (window_box_right, window_box_right_offset): Declare extern.
16269 Otherwise, these inline functions do not conform to C99 and
16270 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
16271 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
16272 * intervals.c (adjust_intervals_for_insertion)

16275 (static_offset_intervals): Remove.
16276 (offset_intervals): Rewrite using the old contents of
16277 static_offset_intervals. The old version didn't conform to C99
16278 because an extern inline function contained a reference to an

16432 HAVE_GTK3 (Bug#9869).
16434 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
16435 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
16437 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
16439 * xterm.c: Declare x_handle_net_wm_state to return int.
16440 (handle_one_xevent): Check if we are iconified but don't have
16441 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
16442 (get_current_wm_state): Return non-zero if not hidden,
16443 check for _NET_WM_STATE_HIDDEN (Bug#9893).
16444 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
16445 (x_handle_net_wm_state): Return what get_current_wm_state returns.
16446 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
16448 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
16450 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
16451 so that this new function doesn't get optimized away by a
16452 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
16454 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
16456 * frame.h (MOUSE_HL_INFO): Remove excess parens.
16458 2011-10-29 Eli Zaretskii <eliz@gnu.org>
16460 Fix the `xbytecode' command.
16461 * .gdbinit (xprintbytestr): New command.
16462 (xwhichsymbols): Rename from `which'; all callers changed.
16463 (xbytecode): Print the byte-code string as well.
16465 2011-10-29 Kim Storm <storm@cua.dk>
16467 * alloc.c (which_symbols): New function.
16469 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
16471 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
16474 2011-10-29 Glenn Morris <rgm@gnu.org>
16476 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
16477 Not clear what it was for, and it causes various bugs. (Bug#9839)
16479 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16481 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
16482 possible random value that matches one of those tested as
16483 condition to clear the mouse face.
16485 2011-10-28 Chong Yidong <cyd@gnu.org>
16487 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
16489 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
16491 * window.c (make_window): Initialize phys_cursor_on_p.
16493 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
16495 * lisp.h (struct Lisp_Symbol): Update comments.
16497 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
16499 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
16501 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16503 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
16504 <oslsachem@gmail.com> for helping to debug this.
16506 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
16507 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
16508 (g_b_init_get_glyph_outline_w): New static variables.
16509 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
16510 (GetGlyphOutlineW_Proc): New typedefs.
16511 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
16512 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
16514 (w32font_open_internal, compute_metrics):
16515 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16516 instead of calling the "wide" APIs directly.
16518 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
16520 * w32.h (syms_of_w32font): Add prototype.
16522 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16524 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
16525 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
16526 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
16527 (Fmove_to_window_line): Doc fix.
16529 2011-10-27 Chong Yidong <cyd@gnu.org>
16531 * process.c (make_process): Set gnutls_state to NULL.
16533 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
16534 non-NULL, regardless of GNUTLS_INITSTAGE.
16535 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
16536 an error. Set process slots as soon as we allocate them.
16538 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
16540 2011-10-27 Chong Yidong <cyd@gnu.org>
16542 * gnutls.c (emacs_gnutls_deinit): New function.
16543 Deallocate credentials structures as well as calling gnutls_deinit.
16544 (Fgnutls_deinit, Fgnutls_boot): Use it.
16546 * process.c (make_process): Initialize GnuTLS credentials to NULL.
16547 (deactivate_process): Call emacs_gnutls_deinit.
16549 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16551 * image.c (x_create_x_image_and_pixmap):
16552 * w32.c (sys_rename, w32_delayed_load):
16553 * w32font.c (fill_in_logfont):
16554 * w32reg.c (x_get_string_resource): Silence compiler warnings.
16556 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
16558 * w32fns.c (w32_default_color_map): New function,
16559 extracted from Fw32_default_color_map.
16560 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
16562 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
16564 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
16566 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
16568 * keyboard.c (test_undefined): New function (bug#9751).
16569 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
16571 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
16573 * sysdep.c (init_sys_modes): Fix the check for the controlling
16574 terminal (Bug#6649).
16576 2011-10-20 Eli Zaretskii <eliz@gnu.org>
16578 * dispextern.h (struct bidi_it): New member next_en_type.
16580 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16581 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16582 current character, check also for next_en_type being WEAK_EN.
16583 (bidi_resolve_weak): Don't enter the expensive loop if the current
16584 position is before next_en_pos. Record the bidi type of the first
16585 non-ET, non-BN character we find, in addition to its position.
16586 (bidi_level_of_next_char): Invalidate next_en_type when
16587 next_en_pos is over-stepped.
16589 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16591 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16592 * editfns.c: Rewrite current-time-zone so that it invokes
16593 the equivalent of (format-time-string "%Z") to get the time zone name.
16594 This fixes a bug when the time zone name contains characters that
16595 need converting from the system time locale to Emacs internal format.
16596 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16597 that patch fixed format-time-string to do the conversion, but
16598 I forgot to fix current-time-zone.
16599 (format_time_string): New function, containing most of
16600 what Fformat_time_string used to contain.
16601 (Fformat_time_string): Rewrite in terms of format_time_string.
16602 This doesn't change this function's behavior.
16603 (current-time-zone): Rewrite to use format_time_string.
16604 This fixes the bug reported by Michael Schierl in
16605 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16606 Jason Rumney's 2007-06-07 change worked around this bug, but
16608 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16610 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16612 * xdisp.c (start_display): If the character at POS is displayed
16613 via a display vector, reset IT->current.dpvec_index to zero.
16614 (try_window_reusing_current_matrix): If a line ends in a display
16615 vector or the next line starts in a display vector, continue
16616 redrawing the window even though the character position of
16617 start_row was reached.
16620 2011-10-18 Chong Yidong <cyd@gnu.org>
16622 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16623 with nobreak-char-display too.
16625 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16627 Fix part 3 of bug#9771.
16628 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16629 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16630 non-neutral characters if the current character is a paragraph
16631 separator (a.k.a. Newline). This avoids running the same
16632 expensive loop twice, once when we consume the preceding newline
16633 and the other time when the line actually needs to be displayed.
16634 Avoid the loop when we see neutrals on the base embedding level
16635 following a character whose directionality is the same as the
16636 paragraph's. This avoids running the expensive loop when a line
16637 ends in a long sequence of neutrals, like control characters.
16638 Add assertion against STRONG_AL type. Slightly rearrange code
16639 that determines the type of a neutral given the first non-neutral
16641 (bidi_level_of_next_char): Set next_en_pos to zero when
16642 invalidating its info.
16644 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16646 * xdisp.c (push_display_prop): Determine whether to record string
16647 or buffer position by IT->string, not by IT->method. Allow
16648 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16649 (move_it_vertically_backward): Don't look for character position
16650 immediately after the newline when in a continuation line.
16653 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16655 * window.c (coordinates_in_window): Rewrite and delabelize
16656 vertical border check. (Bug#5357) (Bug#9618)
16658 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16660 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16661 errors in XSetWindowBorder (bug#9310).
16663 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16665 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16666 avoid crash when xmalloc overrun checking is enabled.
16668 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16670 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16671 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16672 cursor motion with <left> and <right> arrow keys.
16674 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16675 some callers set that themselves.
16677 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16679 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16680 display string and the previous row comes from the same string and
16681 is empty. (Bug#9739) (Bug#9738)
16683 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16685 * doc.c (get_doc_string): Encode file name (bug#9735).
16687 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16689 * bidi.c (bidi_level_of_next_char):
16690 * xdisp.c (get_visually_first_element): Remove old incorrect
16691 comments regarding the Unicode Line Separator character.
16693 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16695 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16697 * alloc.c (Fgc_status): Do not access beyond zombies array
16698 boundary if nzombies > MAX_ZOMBIES.
16699 * alloc.c (dump_zombies): Add missing format specifier.
16701 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16703 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16704 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16706 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16707 Some packages use them to denote characters with modifiers.
16709 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16711 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16712 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16713 matching a pp-number. Rename parameter var to var1.
16715 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16717 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16719 2011-10-08 Glenn Morris <rgm@gnu.org>
16721 * callint.c (Fcall_interactively): Give a more explicit error for the
16722 'c' case with a non-character input. (Bug#8479)
16724 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16726 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16728 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16729 lines that are hscrolled on the left.
16731 * dispnew.c (buffer_posn_from_coords): Account for a possible
16732 presence of header-line. (Bug#4426)
16734 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16736 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16737 Don't advertise functionality which we discourage or doesn't work.
16739 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16741 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16742 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16743 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16744 this makes Emacs dump core during garbage collection on rare
16745 occasions. sizeof is obviously inferior to offsetof here, so
16746 stick with offsetof.
16747 (GC_POINTER_ALIGNMENT): New macro.
16748 (mark_memory): Omit 3rd (offset) arg; caller changed.
16749 Don't assume EMACS_INT alignment is the same as pointer alignment.
16751 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16753 * keyboard.c (read_key_sequence_remapped): New var.
16754 (read_key_sequence): Compute remapping in the right buffer.
16755 (command_loop_1): Use read_key_sequence's remapping directly.
16757 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16759 * dired.c (file_name_completion): Don't expand file name.
16760 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16761 before checking file name handler.
16763 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16764 they've been requested explicitly (bug#9591).
16766 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16768 * keymap.c (Fsingle_key_description): Use make_specified_string
16769 instead of build_string to build string from push_key_description.
16772 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16774 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16775 This fixes a Y2038 bug on 64-bit hosts.
16776 * buffer.c (reset_buffer):
16777 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16778 (Fclear_buffer_auto_save_failure):
16779 Use 0, not -1, to represent an unset failure time, since time_t
16780 might not be signed.
16782 Remove dependency on glibc malloc internals.
16783 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16784 Move back here from lisp.h, but with their new implementations.
16785 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16786 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16787 * charset.c (charset_table_init): New static var.
16788 (syms_of_charset): Use it instead of xmalloc. This removes a
16789 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16790 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16791 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16792 Move back to alloc.c.
16793 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16794 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16796 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16798 * nsterm.m (windowDidResize): Call x_set_window_size only when
16799 ns_in_resize is true. Otherwise set pixelwidth/height and
16800 call change_frame_size (Bug#9628).
16802 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16804 Port --enable-checking=all to Fedora 14 x86-64.
16805 * charset.c (syms_of_charset): Also account for glibc malloc's
16806 internal overhead when calculating the initial malloc maximum.
16808 Port --enable-checking=all to Fedora 14 x86.
16809 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16811 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16812 (overrun_check_realloc, overrun_check_free):
16813 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16814 That way, xmalloc returns a properly-aligned pointer even if
16815 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16816 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16817 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16818 into account when calculating the initial malloc maximum.
16819 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16820 Move here from alloc.c, so that charset.c can use it too.
16821 Properly align; the old code wasn't right for common 32-bit hosts
16822 when configured with --enable-checking=all.
16823 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16824 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16826 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16828 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16831 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16833 * xdisp.c (compute_display_string_end): If there's no display
16834 string at CHARPOS, return -1.
16836 * bidi.c (bidi_fetch_char): When compute_display_string_end
16837 returns a negative value, treat the character as a normal
16838 character not covered by a display string. (Bug#9624)
16840 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16842 * lread.c (Fread_from_string): Fix typo in docstring.
16844 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16846 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16847 newline, reseat the iterator instead of bidi-iterating there one
16848 character at a time. (Bug#9610)
16849 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16850 TO_CHARPOS if the bidi iterator is at base embedding level.
16852 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16854 * lread.c (readevalloop): Use correct code for NBSP.
16855 (read1): Likewise. (Bug#9608)
16857 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16859 * dbusbind.c (Fdbus_register_signal): When service is not
16860 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16862 2011-09-25 Glenn Morris <rgm@gnu.org>
16864 * buffer.c (truncate-lines): Doc fix.
16866 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16868 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16869 (Fset_window_next_buffers): Doc fix.
16871 2011-09-24 Glenn Morris <rgm@gnu.org>
16873 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16875 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16877 Fix minor problems found by static checking.
16878 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16879 * indent.c (Fvertical_motion): Fix == vs = typo.
16881 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16883 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16884 Default value is now t. Doc fix.
16886 * indent.c (Fvertical_motion): Compute and apply the overshoot
16887 logic when moving up, not only when moving down. Fix the
16888 confusing name and values of the it_overshoot_expected variable;
16889 logic changes accordingly. (Bug#9254) (Bug#9549)
16891 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16892 CHARPOS is covered by a display string which includes newlines.
16893 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16894 is covered by a display string with embedded newlines.
16896 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16898 * dbusbind.c (Fdbus_register_signal): Add match rule to
16899 Vdbus_registered_objects_table. (Bug#9581)
16900 (Fdbus_register_method, Vdbus_registered_objects_table):
16903 2011-09-24 Jim Meyering <meyering@redhat.com>
16905 do not ignore write error for any output size
16906 The previous change was incomplete.
16907 While it makes emacs --batch detect the vast majority of stdout
16908 write failures, errors were still ignored whenever the output size is
16909 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16910 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16911 && echo FAIL: ignored write error
16912 FAIL: ignored write error
16913 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16914 && echo FAIL: ignored write error
16915 FAIL: ignored write error
16916 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16918 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16920 * emacs.c (Fkill_emacs): In noninteractive mode exit
16921 non-successfully if a write error occurred on stdout. (Bug#9574)
16923 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16925 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16928 * dispextern.h (struct it): Update the comment documenting what
16931 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16933 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16934 a display string, extend search for cursor position to end of row.
16935 (find_row_edges): If the row ends in a newline from a display
16936 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16937 Handle the case of a display string with multiple newlines.
16938 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16939 non-empty line. Fixes confusing cursor motion with arrow keys at
16940 the beginning of a line that starts with whitespace.
16942 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16944 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16947 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16949 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16950 boolean (Bug#9154).
16952 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16954 * xdisp.c (display_line): Record maximum and minimum buffer
16955 positions even if no glyphs were produced (e.g., by a zero-width
16956 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16957 buffer positions that will be removed from the glyph row because
16959 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16960 column is beyond frame width: don't subtract 1 "pixel" when
16961 computing width of the stretch.
16962 (reseat_at_next_visible_line_start): Undo the change made on
16963 2011-09-17 that saved paragraph information and restored it after
16964 the call to `reseat'. (Bug#9545)
16966 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16968 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16969 and turn window cursor on if cleared (Bug#9415).
16971 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16973 * search.c (boyer_moore): Take unibyte characters from pattern
16974 literally. (Bug#9458)
16976 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16978 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16980 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16982 Fix minor problem found by static checking.
16983 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16984 initialized, to pacify gcc -Wuninitialized.
16986 * fileio.c: Report proper errno when syscall falls.
16987 (Finsert_file_contents): Save and restore errno,
16988 so that report_file_error outputs the correct diagnostic.
16989 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16991 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16993 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16995 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16997 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16998 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
17000 2011-09-17 Eli Zaretskii <eliz@gnu.org>
17002 * xdisp.c (reseat_at_next_visible_line_start): Keep information
17003 about the current paragraph and restore it after the call to reseat.
17005 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
17006 (bidi_find_paragraph_start): Search back for paragraph beginning
17007 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
17008 (bidi_move_to_visually_next): Only trigger paragraph-related
17009 computations when the last character is a newline or at EOB, not
17010 just any NEUTRAL_B. (Bug#9470)
17012 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
17013 truncated lines if point is covered by a display string. (Bug#9524)
17015 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
17017 * xselect.c: Relax test for outgoing X longs (Bug#9498).
17018 (cons_to_x_long): New function.
17019 (lisp_data_to_selection_data): Use it. Correct the test for
17020 short-versus-long data; it was negated. Break out of vector
17021 loop, for efficiency, when a long datum is discovered.
17023 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
17025 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
17027 2011-09-16 Eli Zaretskii <eliz@gnu.org>
17029 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
17030 GCC PR/17406) by declaring this function with external scope.
17032 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
17034 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
17035 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
17037 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
17039 * editfns.c (Fformat): Correctly handle text properties on "%%".
17041 2011-09-15 Eli Zaretskii <eliz@gnu.org>
17043 * xterm.c (x_draw_composite_glyph_string_foreground):
17044 * w32term.c (x_draw_composite_glyph_string_foreground):
17045 * term.c (encode_terminal_code):
17046 * composite.c (composition_update_it, get_composition_id):
17047 * xdisp.c (get_next_display_element)
17048 (fill_composite_glyph_string): Add comments about special meaning
17049 of TAB characters in a composition.
17051 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
17053 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
17054 This occurs when processing a multibyte format.
17055 Problem reported by Wolfgang Jenker.
17057 2011-09-15 Johan Bockgård <bojohan@gnu.org>
17059 * xdisp.c (try_cursor_movement): Only check for exact match if
17060 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
17062 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
17064 Remove unused external symbols.
17065 * dispextern.h (calc_pixel_width_or_height): Remove decl.
17066 * xdisp.c (calc_pixel_width_or_height): Now static.
17067 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
17068 * indent.c (check_display_width):
17069 * w32term.c: Fix comment to match code.
17070 * xterm.c, xterm.h (x_catching_errors): Remove.
17072 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
17074 * xselect.c: Use signed conversions more consistently (Bug#9498).
17075 (selection_data_to_lisp_data): Assume incoming selection data are
17076 signed integers, not unsigned. This is to be consistent with
17077 outgoing selection data, which was modified to use signed integers
17078 in as part of the fix to Bug#9196 in response to Jan D.'s comment
17079 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
17080 expects long, not unsigned long.
17082 2011-09-14 Eli Zaretskii <eliz@gnu.org>
17084 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
17085 computation of loop end. Reported by Johan Bockgård
17088 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
17090 * frame.c (Fother_visible_frames_p): Function deleted.
17092 2011-09-12 Eli Zaretskii <eliz@gnu.org>
17094 * indent.c (compute_motion): Process display vector front to back
17095 rather than the other way around. (Bug#2496)
17097 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
17099 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
17101 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
17103 * minibuf.c (Fread_from_minibuffer): Doc fix.
17105 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17107 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
17108 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
17110 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
17112 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
17113 value for non-existent files.
17115 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17117 * fileio.c (Finsert_file_contents): If the file cannot be opened,
17118 set its "size" to -1. This will set the modtime_size field of
17119 the corresponding buffer to -1, which is what
17120 verify-visited-file-modtime expects for files that do not exist.
17123 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
17125 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
17127 * lisp.h: ... from here. push_key_description is no longer
17128 defined in keyboard.c, so its declaration should not be in
17129 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
17130 logically belongs with push_key_description.
17132 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
17134 * buffer.h: Include <sys/types.h> instead of <time.h>.
17135 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
17136 Problem reported by Herbert J. Skuhra.
17138 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
17140 * xml.c (parse_region): Make the parsing work for
17141 non-comment-starting XML files again (bug#9144).
17143 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
17145 * image.c (gif_load): Fix calculation of bottom and right corner.
17148 2011-09-10 Eli Zaretskii <eliz@gnu.org>
17150 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
17151 redisplay in small windows.
17153 2011-09-09 Eli Zaretskii <eliz@gnu.org>
17155 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
17157 2011-09-08 Martin Rudalics <rudalics@gmx.at>
17159 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
17160 Operate on live windows only.
17162 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
17164 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
17166 2011-09-07 Eli Zaretskii <eliz@gnu.org>
17168 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
17169 only under bidi iteration.
17171 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17173 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17175 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17177 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17178 Without this fix, the command to link temacs failed due to an
17179 undefined symbol __builtin_isnan. This is because
17180 /usr/include/iso/math_c99.h #defines isnan(x) to
17181 __builtin_isnan(x), but the bundled gcc, which identifies itself
17182 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17184 * floatfns.c (isnan): #undef, and then #define to a clone of
17186 (Fisnan): Always define, since it's always available now.
17187 (syms_of_floatfns): Always define isnan at the Lisp level.
17189 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17191 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17193 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17195 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17196 The previous code assumed that file offsets (off_t values) fit in
17197 EMACS_INT variables, which is not true on typical 32-bit hosts.
17198 The code messed up by falsely reporting buffer overflow in cases
17199 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17200 when "big" contains more than 2**29 bytes, even though this
17201 inserts just one byte and does not overflow the buffer.
17202 (Finsert_file_contents): Store file offsets as off_t
17203 values, not as EMACS_INT values. Check for overflow when
17204 converting between EMACS_INT and off_t. When checking for
17205 buffer overflow or for overlap, take the offsets into account.
17206 Don't use EMACS_INT for small values where int suffices.
17207 When checking for overlap, fix a typo: ZV was used where
17208 ZV_BYTE was intended.
17209 (Fwrite_region): Don't assume off_t fits into 'long'.
17210 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17212 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17214 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17216 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17218 sprintf-related integer and memory overflow issues (Bug#9412).
17220 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17221 (esprintf, exprintf, evxprintf): New functions.
17222 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17223 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17224 (modify_event_symbol): Do not assume that the length of
17225 name_alist_or_stem is safe to alloca and fits in int.
17226 (Fexecute_extended_command): Likewise for function name and binding.
17227 (Frecursion_depth): Wrap around reliably on integer overflow.
17228 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17229 since some callers pass EMACS_INT values.
17230 (Fsingle_key_description): Don't crash if symbol name contains more
17231 than MAX_ALLOCA bytes.
17232 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17233 (get_minibuffer): Arg is now EMACS_INT, not int.
17234 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17235 (esprintf, exprintf, evxprintf): New decls.
17236 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17238 * dbusbind.c (signature_cat): New function.
17239 (xd_signature, Fdbus_register_signal):
17240 Do not overrun buffer; instead, report string overflow.
17242 * dispnew.c (add_window_display_history): Don't overrun buffer.
17243 Truncate instead; this is OK since it's just a log.
17245 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17246 even if the time zone offset is outlandishly large.
17247 Don't mishandle offset == INT_MIN.
17249 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17250 when creating daemon; the previous buffer-overflow check was incorrect.
17252 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17253 which has the guts of the old verror function.
17255 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17256 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17258 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17259 (font_unparse_xlfd): Don't blindly alloca long strings.
17260 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17261 fits in int, when using sprintf. Use single snprintf to count
17262 length of string rather than counting it via multiple sprintfs;
17263 that's simpler and more reliable.
17264 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17265 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17266 sprintf, in case result does not fit in int.
17268 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17269 (fontset_from_font): Print it.
17271 * frame.c (tty_frame_count): Now printmax_t, not int.
17272 (make_terminal_frame, set_term_frame_name): Print it.
17273 (x_report_frame_params): In X, window IDs are unsigned long,
17274 not signed long, so print them as unsigned.
17275 (validate_x_resource_name): Check for implausibly long names,
17276 and don't assume name length fits in 'int'.
17277 (x_get_resource_string): Don't blindly alloca invocation name;
17278 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17281 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17282 (xg_check_special_colors, xg_set_geometry):
17283 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17285 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17286 Use esprintf, not sprintf, in case result does not fit in int.
17288 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17289 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17290 it as a large positive number.
17291 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17292 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17294 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17295 in case result does not fit in int.
17297 * print.c (float_to_string): Detect width overflow more reliably.
17298 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17299 buffer overrun. Don't assume list length fits in 'int'. Treat
17300 print length of 0 as 0, not as infinity; to be consistent with other
17301 uses of print length in this function. Don't overflow print length
17302 index. Don't assume hash table size fits in 'long', or that
17303 vectorlike size fits in 'unsigned long'.
17305 * process.c (make_process): Use printmax_t, not int, to format
17306 process-name gensyms.
17308 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17310 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17311 to avoid potential buffer overrun.
17313 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17314 if X resource line is longer than 512 bytes.
17316 * xfns.c (x_window): Make sprintf buffer a bit bigger
17317 to avoid potential buffer overrun.
17319 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17321 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17323 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17325 Integer overflow fixes for scrolling, etc.
17326 Without these, Emacs silently mishandles large integers sometimes.
17327 For example, "C-u 4294967297 M-x recenter" was treated as if
17328 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17330 * xdisp.c (try_window_id): Check Emacs fixnum range before
17331 converting to 'int'.
17333 * window.c (window_scroll_line_based, Frecenter):
17334 Check that an Emacs fixnum is in range before assigning it to 'int'.
17335 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17336 values converted from Emacs fixnums.
17337 (Frecenter): Don't wrap around a line count if it is out of 'int'
17338 range; instead, treat it as an extreme value.
17339 (Fset_window_configuration, compare_window_configurations):
17340 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17342 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17343 that can exceed INT_MAX. Check that EMACS_INT value is in range
17344 before assigning it to the (possibly-narrower) index.
17345 (match_limit): Don't assume that a fixnum can fit in 'int'.
17347 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17350 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17351 (Fvertical_motion): Don't wrap around LINES values that don't fit
17352 in 'int'. Instead, treat them as extreme values. This is good
17353 enough for windows, which can't have more than INT_MAX lines anyway.
17355 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17357 * Require libxml/parser.h to avoid compilation warning.
17359 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17361 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17362 since this reportedly can destroy thread storage.
17364 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17366 * syntax.c (find_defun_start): Update all cache variables if
17367 exiting early (Bug#9401).
17369 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17371 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17373 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17374 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17375 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17377 * term.c (tty_append_glyph): New function.
17378 (produce_stretch_glyph): Static function and its prototype deleted.
17380 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17383 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17385 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17386 when checking :margin (Bug#9390).
17387 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17388 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17389 so that the name doesn't mislead. All uses changed.
17391 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17393 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
17396 2011-08-27 Eli Zaretskii <eliz@gnu.org>
17398 * xdisp.c (move_it_to): Don't bail out early when reaching
17399 position beyond to_charpos, if we are scanning backwards.
17400 (move_it_vertically_backward): When DY == 0, make sure we get to
17401 the first character in the line after the newline.
17403 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17405 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17406 (ccl_driver): Do not generate an out-of-range pointer.
17407 (Fccl_execute_on_string): Remove unnecessary check for
17408 integer overflow, noted by Stefan Monnier in
17409 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17410 Remove a FIXME that didn't need fixing.
17411 Simplify the newly-introduced buffer reallocation code.
17413 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17415 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17417 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17419 Integer and memory overflow issues (Bug#9196).
17421 * doc.c (get_doc_string): Rework so that
17422 get_doc_string_buffer_size is the actual buffer size, rather than
17423 being 1 less than the actual buffer size; this makes xpalloc more
17426 * image.c (x_allocate_bitmap_record, cache_image):
17427 * xselect.c (Fx_register_dnd_atom):
17428 Simplify previous changes by using xpalloc.
17430 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17431 since either will do and ptrdiff_t is convenient with xpalloc.
17433 * charset.c (charset_table_size)
17434 (struct charset_sort_data.priority): Now ptrdiff_t.
17435 (charset_compare): Don't overflow if priorities differ greatly.
17436 (Fsort_charsets): Don't assume list length fits in int.
17437 Check for size-calculation overflow when allocating sort data.
17438 (syms_of_charset): Allocate an initial charset table that is
17439 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17441 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17443 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17444 The actual value is always <= INT_MAX, and leaving it unsigned made
17445 overflow checking harder.
17447 * dispextern.h (struct glyph_matrix.rows_allocated)
17448 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17449 with xpalloc. The values are still always <= INT_MAX.
17451 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17453 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17454 (SAFE_NALLOCA): New macro.
17456 * region-cache.c (struct boundary.pos, find_cache_boundary)
17457 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17458 (set_cache_region, invalidate_region_cache)
17459 (revalidate_region_cache, know_region_cache, region_cache_forward)
17460 (region_cache_backward, pp_cache):
17461 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17462 so that ptrdiff_t * can be passed to xpalloc.
17463 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17464 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17465 (pp_cache): Don't assume cache_len fits in int.
17466 * region-cache.h: Adjust extern decls to match.
17468 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17469 EMACS_INT, since either will do, for xpalloc.
17471 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17472 (xnmalloc, xnrealloc, xpalloc): New functions.
17474 * bidi.c (bidi_shelve_header_size): New constant.
17475 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17476 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17478 * bidi.c (bidi_cache_shrink):
17479 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17481 Don't update size of array until after memory allocation succeeds,
17482 because xmalloc/xrealloc may not return.
17483 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17484 now that we have proper integer overflow checking.
17485 (record_overlay_string, overlay_strings): Catch overflows when
17486 calculating size of overlay_str_buf.
17488 * callproc.c (Fcall_process): Check for size overflow when
17489 calculating size of args2.
17490 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17491 Normally we prefer signed values, but sticking with ptrdiff_t would
17492 require adding more-complicated checks.
17494 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17495 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17496 Redo buffer-overflow calculations to avoid integer overflow.
17497 Add a FIXME comment where memory seems to be over-allocated.
17499 * character.c (Fstring): Check for size-calculation overflow.
17501 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17502 unnecessary integer overflow. Check for size overflow.
17503 (encode_coding_object): Don't update size until xmalloc succeeds.
17505 * composite.c (get_composition_id): Check for overflow in glyph
17506 length calculations.
17508 Integer and memory overflow fixes for display code.
17509 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17510 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

17523 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
17524 (get_doc_string): Check for size calculation overflow.
17525 Don't update size until allocation succeeds.
17526 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
17527 EMACS_INT, where ptrdiff_t will do.
17528 (Fsubstitute_command_keys): Check for string overflow.

17532 (message_length): Now ptrdiff_t, not int.
17533 (Fmessage_box): Don't update size until allocation succeeds.
17534 Don't assume message length fits in int.
17535 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17537 * emacs.c (main): Do not reallocate argv, since there is a null at
17538 the end that can be overwritten, and this way there's no need to
17539 worry about size-calculation overflow.
17540 (sort_args): Check for size-calculation overflow.
17542 * eval.c (init_eval_once, grow_specpdl): Don't update size until
17544 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
17546 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
17547 (x_set_scroll_bar_width, x_figure_window_size):
17548 Check for integer overflow.
17549 (x_set_alpha): Do not assume XINT fits in int.
17551 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17552 This is for the members text_lines, text_cols, total_lines, total_cols,
17553 where the system imposes an 'int' limit.
17555 * fringe.c (Fdefine_fringe_bitmap):
17556 Don't update size until alloc works.
17558 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
17559 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
17561 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
17562 Check for size-calculation overflow.
17563 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17564 do, as we prefer signed integers.
17565 (id_to_widget.max_size, id_to_widget.used)
17566 (xg_store_widget_in_map, xg_remove_widget_from_map)
17567 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
17568 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
17569 Use and return ptrdiff_t, not int.
17570 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
17571 * gtkutil.h: Change prototypes to match the above.
17573 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
17574 are duplicate now that they've been promoted to lisp.h.
17575 (x_allocate_bitmap_record, x_alloc_image_color)
17576 (make_image_cache, cache_image, xpm_load):
17577 Don't update size until alloc is done.

17588 Use ptrdiff_t, not int, to count maps.
17589 (read_char_minibuf_menu_prompt): Check for overflow in size
17590 calculations. Don't update size until allocation succeeds.
17591 Redo calculations to avoid overflow.
17592 * keyboard.h: Change prototypes to match the above.
17594 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

17620 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17621 for command line length. Do not attempt to address one before the
17622 beginning of an array, as that's not portable.
17624 * term.c (max_frame_lines): Remove; unused.
17625 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
17627 (encode_terminal_code, calculate_costs): Check for size

17650 Use ptrdiff_t, not int, for sizes.
17651 (Finternal_make_lisp_face, cache_face):
17652 Check for size calculation overflow.
17653 (cache_face): Treat size calculation overflows as if they were

17657 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17658 sizes, since they can exceed INT_MAX in size. Check for size

17662 (xg_select): Check for size calculation overflow.
17663 Don't update size until alloc done.
17665 * xrdb.c (get_environ_db): Don't assume path length fits in int,
17666 as sprintf is limited to int lengths.
17668 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17669 (X_LONG_MIN): New macros.
17670 Use them to make the following changes clearer.
17671 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17672 This change doesn't affect the value now, but it may help remind
17673 future maintainers not to raise the value too much later.
17674 (SELECTION_QUANTUM): Remove, replacing with ...
17675 (selection_quantum): ... new function, which avoids overflow.
17677 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17678 assumption that selection length fits in 'int'.

17690 (x_get_window_property, receive_incremental_selection)
17691 (lisp_data_to_selection_data, x_property_data_to_lisp):

17695 Don't store size until memory allocation succeeds.
17696 (x_get_window_property): Plug memory leak on memory exhaustion.
17697 Don't double-block input; malloc is safe here. Don't assume 2**34
17698 - 4 fits in unsigned long. Add an xassert to check
17699 XGetWindowProperty overflow. Be more careful about overflow
17700 calculations, and distinguish size from memory overflow better.
17701 (receive_incremental_selection): When tracing, don't assume
17702 unsigned int is less than INT_MAX.
17703 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
17704 harmful) conversions of unsigned short to int.
17705 (lisp_data_to_selection_data): Don't assume that integers
17706 in the range -65535 through -1 fit in an X unsigned short.
17707 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17708 result parameters unless successful. Rely on cons_to_unsigned
17709 to report problems with elements; the old code wasn't right anyway.
17710 (x_check_property_data): Check for int overflow; we cannot use
17711 a wider type due to X limits.
17712 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

17744 * lisp.h (hash_lookup, hash_put):
17745 * minibuf.c (Ftest_completion):
17746 Use ptrdiff_t for hash table indexes, not int (which is too
17747 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17748 32-bit --with-wide-int hosts).
17750 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17751 Add a FIXME comment about memory leaks.
17752 (syms_of_charset): Don't assume xmalloc returns.
17754 Don't assume that stated character widths fit in int.

17757 * indent.c (MULTIBYTE_BYTES_WIDTH):
17758 Use sanitize_char_width to avoid undefined and/or bad behavior
17759 with outlandish widths.
17760 * character.h (sanitize_tab_width): Rename from sanitize_width,
17761 now that we have two such functions. All uses changed.
17762 (sanitize_char_width): New inline function.
17764 Don't assume that tab-width fits in int.
17765 * character.h (sanitize_width): New inline function.
17766 (SANE_TAB_WIDTH): New macro.
17767 (ASCII_CHAR_WIDTH): Use it.

17772 * fileio.c: Integer overflow issues with file modes.
17773 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
17775 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
17776 Remove unreachable code.
17777 (read_hex, load_charset_map_from_file): Check for integer overflow.
17779 * xterm.c: Don't go over XClientMessageEvent limit.
17780 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17781 (x_send_scroll_bar_event): Likewise. Check that the size does not
17782 exceed limits imposed by XClientMessageEvent, as well as the usual
17783 ptrdiff_t and size_t limits.
17785 * keyboard.c: Overflow, signedness and related fixes.
17786 (make_lispy_movement): Use same integer type in forward decl
17787 that is used in the definition.
17788 (read_key_sequence, keyremap_step):
17789 Change bufsize argument back to int, undoing my 2011-03-30 change.
17790 We prefer signed types, and int is wide enough here.
17791 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17792 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17793 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17794 length, not size_t. Use ptrdiff_t for index, not int.
17795 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17796 possibility of integer overflow.
17798 Overflow, signedness and related fixes for images.
17800 * dispextern.h (struct it.stack[0].u.image.image_id)
17801 (struct_it.image_id, struct image.id, struct image_cache.size)
17802 (struct image_cache.used, struct image_cache.ref_count):

17808 * xdisp.c (calc_pixel_width_or_height):
17809 * xfns.c (image_cache_refcount):
17810 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
17811 on typical 64-bit hosts.

17817 when the callers expect that.
17818 (image_ascent): Redo ascent calculation to avoid int overflow.
17819 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17820 (lookup_image): Remove unnecessary tests.
17821 (xbm_image_p): Locals are now of int, not EMACS_INT,
17822 since parse_image_check makes sure they fit into int.
17823 (png_load, gif_load, svg_load_image):
17824 Prefer int to unsigned where either will do.
17825 (tiff_handler): New function, combining the cores of the
17826 old tiff_error_handler and tiff_warning_handler.
17827 This function is rewritten to use vsnprintf and thereby avoid
17828 stack buffer overflows. It uses only the features of vsnprintf
17829 that are common to both POSIX and native Microsoft.
17830 (tiff_error_handler, tiff_warning_handler): Use it.
17831 (tiff_load, gif_load, imagemagick_load_image):
17832 Don't assume :index value fits in 'int'.
17833 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17834 (imagemagick_load_image): Check that crop parameters fit into
17835 the integer types that MagickCropImage accepts. Don't assume
17836 Vimagemagick_render_type has a nonnegative value. Don't assume
17837 size_t fits in 'long'.
17838 (gs_load): Use printmax_t to print the widest integers possible.
17839 Check for integer overflow when computing image height and width.
17841 2011-08-26 Eli Zaretskii <eliz@gnu.org>
17843 * xdisp.c (redisplay_window): Don't force window start if point

17851 handle_single_display_spec, not just 1 or zero.
17852 (handle_single_display_spec): If the display spec is of the form
17853 `(space ...)', and specifies display in the text area, return 2
17855 (try_cursor_movement): Check for the need to scroll more
17856 accurately, and prefer exact match for point under bidi.
17857 Don't advance `row' beyond the last row of the window.
17859 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17860 into disp_prop; all users changed.
17862 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
17863 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
17864 for the text covered by the display property.

17874 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
17875 buffers, return left-to-right.
17876 (set_cursor_from_row): Consider candidate row a win if its glyph
17877 represents a newline and point is on that newline. Fixes cursor
17878 positioning on the newline at EOL of R2L text within L2R
17879 paragraph, and vice versa.
17880 (try_cursor_movement): Check continued rows, in addition to
17881 continuation rows. Fixes unwarranted scroll when point enters a
17882 continued line of R2L text within an L2R paragraph, or vice versa.
17883 (cursor_row_p): Consider the case of point being equal to
17884 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17885 from the end of a short line to the beginning of a continued line
17886 of R2L text within L2R paragraph.
17887 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
17888 composed characters.
17890 * bidi.c (bidi_check_type): Use xassert.
17891 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
17894 2011-08-23 Eli Zaretskii <eliz@gnu.org>

17901 * nsfont.m (ns_otf_to_script): Fix typo.
17903 2011-08-22 Kenichi Handa <handa@m17n.org>
17905 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17906 extra slot even if the purpose is char-code-property-table.
17908 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17910 * xdisp.c (redisplay_window): When computing centering_position,
17911 account for the height of the header line. (Bug#8874)
17913 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17914 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17915 candidate is selected by the mouse, and that candidate has a
17916 composed character under the mouse.
17918 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17919 coordinates reported by pos-visible-in-window-p for a composed
17920 character in column zero.
17922 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17924 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17926 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17928 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17929 consider it a hit if to_charpos is anywhere in the range of the
17930 composed buffer positions.
17932 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17934 * image.c (gif_load): Don't assume that each subimage has the same
17935 dimensions as the base image. Handle disposal method that is
17936 "undefined" by the gif spec (Bug#9335).
17938 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17940 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17943 2011-08-19 Eli Zaretskii <eliz@gnu.org>
17945 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17946 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17947 from an Org mode buffer to a Speedbar frame.
17949 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17950 a composition, take its buffer position from IT->cmp_it.charpos.
17951 Fixes cursor positioning at the beginning of a line that begins
17952 with a composed character.
17954 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17956 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17957 character bidirectional type, use STRONG_L instead. Fixes crashes
17958 in a buffer produced by `describe-categories'.
17960 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17961 members before the level stack, so they would be saved and
17962 restored when copying iterator state. Fixes incorrect reordering
17963 around TABs covered by display properties.
17965 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17967 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

18037 * xdisp.c (move_it_in_display_line_to): Don't invoke
18038 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
18039 ppos_it. Fixes vertical cursor motion when line beginning is
18040 covered by an image. (Bug#9296)
18042 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
18044 * nsterm.h (ns_run_ascript): Declare.

18048 (ns_run_ascript): New function.
18049 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
18050 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
18051 the event loop. Get status from as_status (Bug#7276).
18053 * nsterm.m (sendEvent): If event is NSApplicationDefined and
18054 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
18055 the event loop (Bug#7276).
18057 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

18081 (Fnetwork_interface_list): Allocate in increments of bytes instead
18082 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
18083 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
18085 (struct ifflag_def): notrailers is smart on OSX.
18086 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
18087 Get hardware address with getifaddrs if available.
18089 2011-08-12 Eli Zaretskii <eliz@gnu.org>
18091 * xdisp.c (iterate_out_of_display_property): xassert that
18092 IT->position is set to within IT->object's boundaries. Break from
18093 the loop as soon as EOB is reached; avoids infloops in redisplay

18095 Set IT->current to match the bidi iterator unconditionally.
18096 (push_display_prop): Allow GET_FROM_STRING as IT->method on
18097 entry. Force push_it to save on the stack the current
18098 buffer/string position, to be restored by pop_it. Fix flags in
18099 the iterator structure wrt the object coming from a display
18100 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
18101 properties. (Bug#9284)
18103 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
18105 * fontset.c (fontset_get_font_group): Add proper type checks.

18133 restore_point_unwind (Bug#5984).
18135 2011-08-07 Juri Linkov <juri@jurta.org>
18137 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
18138 to show the arg `TIME' instead of `TIMEVAL'.

18142 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
18143 display property strides EOL and includes a newline, as in
18144 longlines-mode. (Bug#9254)
18145 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
18146 word-wrap under bidirectional display. (Bug#9224)
18148 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
18149 is non-zero, even if the data buffer is NULL. Fixes a crash in
18150 vertical-motion with longlines-mode. (Bug#9254)
18152 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18154 * bidi.c <bidi_cache_total_alloc>: Now static.

18157 * xdisp.c (display_line): Release buffer allocated for shelved bidi
18160 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
18161 amount allocated this far in `bidi_cache_total_alloc'.
18162 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
18163 non-zero, only free the data buffer without restoring the cache
18164 contents. All callers changed.
18166 * dispextern.h (bidi_unshelve_cache): Update prototype.
18168 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
18169 (move_it_in_display_line, move_it_to)
18170 (move_it_vertically_backward, move_it_by_lines): Replace the call
18171 to xfree to an equivalent call to bidi_unshelve_cache.
18172 (move_it_in_display_line_to): Fix logic of returning
18173 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
18175 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18177 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

18228 * bidi.c (bidi_fetch_char): Accept an additional argument
18229 DISP_PROP_P, and pass it to compute_display_string_pos.
18230 Only handle text covered by a display string if DISP_PROP_P is returned
18231 non-zero. All callers of bidi_fetch_char changed.
18233 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
18235 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
18237 2010-12-03 Don March <don@ohspite.net>
18239 * keymap.c (Fdefine_key): Fix non-prefix key error message when
18240 last character M-[char] is translated to ESC [char] (bug#7541).
18242 2011-08-02 Kenichi Handa <handa@m17n.org>
18244 * lisp.h (uniprop_table): Extern it.
18246 * chartab.c (uniprop_table): Make it non-static.
18248 2011-08-01 Eli Zaretskii <eliz@gnu.org>
18250 * xdisp.c (forward_to_next_line_start): Accept additional argument
18251 BIDI_IT_PREV, and store into it the state of the bidi iterator had
18253 (reseat_at_next_visible_line_start): Use the bidi iterator state
18254 returned by forward_to_next_line_start to restore the state of
18255 it->bidi_it after backing up to previous newline. (Bug#9212)
18257 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
18259 * regex.c (re_comp): Protoize.
18260 (re_exec): Fix return type.
18261 (regexec): Fix type of `ret'. (Bug#9203)
18263 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18265 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
18266 This is needed if max-image-size is a floating-point number.
18268 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18270 * print.c (print_object): Print empty symbol as ##.
18272 * lread.c (read1): Read ## as empty symbol.
18274 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18276 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
18277 setting frame foreground color (Bug#9175).
18278 (x_set_background_color): Likewise.
18280 * nsmenu.m (-setText): Size tooltip dimensions precisely to
18281 contents (Bug#9176).
18282 (EmacsTooltip -init): Remove bezels and add shadows to
18285 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
18286 or scroll bar (Bug#8470).
18288 * nsfont.m (nsfont_open): Remove assignment to voffset and
18289 unnecessary vars hshink, expand, hd, full_height, min_height.
18290 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
18292 * nsterm.h (nsfont_info): Remove voffset field.
18294 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18296 Implement strike-through and overline on NextStep (Bug#8863).
18298 * nsfont.m (nsfont_open): Use underline position provided by font,
18299 instead of hard-coded value of 2.
18300 (nsfont_draw): Call ns_draw_text_decoration instead.
18302 * nsterm.h: Add declaration for ns_draw_text_decoration.
18304 * nsterm.m (ns_draw_text_decoration): New function for drawing
18305 underline, overline, and strike-through.
18306 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
18307 ns_draw_text_decoration. Change treatment of cursor drawing to
18308 accommodate underlining, etc.
18310 2011-07-28 Eli Zaretskii <eliz@gnu.org>
18312 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
18315 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18317 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18318 Without this fix, if a signal arrives just after memory fills up,
18319 'malloc' might be invoked reentrantly.
18321 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18322 In other words, assume that every image size is allowed, on non-X
18323 hosts. This assumption is probably wrong, but it lets Emacs compile.
18325 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18327 * regex.c (re_iswctype): Convert return values to boolean.
18329 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
18331 * xdisp.c (compute_display_string_pos): Don't use cached display
18332 string position if the buffer had its restriction changed.
18335 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18337 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18339 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18341 Integer signedness and overflow and related fixes. (Bug#9079)
18343 * bidi.c: Integer size and overflow fixes.
18344 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18345 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18346 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18347 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18348 (bidi_find_other_level_edge):
18349 Use ptrdiff_t instead of EMACS_INT where either will do.
18350 This works better on 32-bit hosts configured --with-wide-int.
18351 (bidi_cache_ensure_space): Check for size-calculation overflow.
18352 Use % rather than repeated addition, for better worst-case speed.
18353 Don't set bidi_cache_size until after xrealloc returns, because it
18355 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18356 (bidi_cache_ensure_space): Also check that the bidi cache size
18357 does not exceed that of the largest Lisp string or buffer. See Eli
18358 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18360 * alloc.c (__malloc_size_t): Remove.
18361 All uses replaced by size_t. See Andreas Schwab's note
18362 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18364 * image.c: Improve checking for integer overflow.
18365 (check_image_size): Assume that f is nonnull, since
18366 it is always nonnull in practice. This is one less thing to
18367 worry about when checking for integer overflow later.
18368 (x_check_image_size): New function, which checks for integer
18369 overflow issues inside X.
18370 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18371 This removes the need for a memory_full check.
18372 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18373 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18374 (xbm_read_bitmap_data): Change locals back to 'int', since
18375 their values must fit in 'int'.
18376 (xpm_load_image, png_load, tiff_load):
18377 Invoke x_create_x_image_and_pixmap earlier,
18378 to avoid much needless work if the image is too large.
18379 (tiff_load): Treat overly large images as if
18380 x_create_x_image_and_pixmap failed, not as malloc failures.
18381 (gs_load): Use x_check_image_size.
18383 * gtkutil.c: Omit integer casts.
18384 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18385 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18387 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18389 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18390 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18391 would wrongly return t on a 64-bit host.
18393 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18394 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18395 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18396 and therefore cause GCC to emit a bogus diagnostic in some cases.
18398 * image.c: Integer signedness and overflow and related fixes.
18399 This is not an exhaustive set of fixes, but it's time to
18400 record what I've got.
18401 (lookup_pixel_color, check_image_size): Remove redundant decls.
18402 (check_image_size): Don't assume that arbitrary EMACS_INT values
18403 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18404 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18405 (tiff_load, imagemagick_load_image):
18406 Check for overflow in size calculations.
18407 (x_create_x_image_and_pixmap): Remove unnecessary test for
18408 xmalloc returning NULL; that can't happen.
18409 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18410 (xpm_color_bucket): Use better integer hashing function.
18411 (xpm_cache_color): Don't possibly over-allocate memory.
18412 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18413 (gif_memory_source):
18414 Use ptrdiff_t, not int or size_t, to record sizes.
18415 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18416 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18417 either works, as we prefer signed integers.
18418 (tiff_read_from_memory, tiff_write_from_memory):
18419 Return tsize_t, not size_t, since that's what the TIFF API wants.
18420 (tiff_read_from_memory): Don't fail simply because the read would
18421 go past EOF; instead, return a short read.
18422 (tiff_load): Omit no-longer-needed casts.
18423 (Fimagemagick_types): Don't assume size fits into 'int'.
18425 Improve hashing quality when configured --with-wide-int.
18426 * fns.c (hash_string): New function, taken from sxhash_string.
18427 Do not discard information about ASCII character case; this
18428 discarding is no longer needed.
18429 (sxhash-string): Use it. Change sig to match it. Caller changed.
18430 * lisp.h: Declare it.
18431 * lread.c (hash_string): Remove, since we now use fns.c's version.
18432 The fns.c version returns a wider integer if --with-wide-int is
18433 specified, so this should help the quality of the hashing a bit.
18435 * emacs.c: Integer overflow minor fix.
18436 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18437 Define only if GNU_LINUX.
18438 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18440 * dispnew.c: Integer signedness and overflow fixes.
18441 Remove unnecessary forward decls, that were a maintenance hassle.
18442 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18444 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18445 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18446 (prepare_desired_row, line_draw_cost):
18447 Use int, not unsigned, where either works.
18448 (save_current_matrix, restore_current_matrix):
18449 Use ptrdiff_t, not size_t, where either works.
18450 (init_display): Check for overflow more accurately, and without
18451 relying on undefined behavior.
18453 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18454 Remove, replacing with the new symbols in lisp.h. All uses changed.
18455 * fileio.c (make_temp_name):
18456 * filelock.c (lock_file_1, lock_file):
18457 * xdisp.c (message_dolog):
18458 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18459 Use pMd etc. instead.
18460 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18461 replacing the pWIDE etc. symbols removed from editfns.c.
18463 * keyboard.h (num_input_events): Now uintmax_t.
18464 This is (very slightly) less likely to mess up due to wraparound.
18467 * buffer.c: Integer signedness fixes.
18468 (alloc_buffer_text, enlarge_buffer_text):
18469 Use ptrdiff_t rather than size_t when either will do, as we prefer
18472 * alloc.c: Integer signedness and overflow fixes.
18473 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18474 (__malloc_size_t): Default to size_t, not to int.
18475 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18476 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18477 Prefer ptrdiff_t to size_t when either would do, as we prefer
18479 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18480 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18481 Now const. Initialize with values that are in range even if char
18483 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18484 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18485 These functions do the right thing with sizes > 2**32.
18486 (check_depth): Now ptrdiff_t, not int.
18487 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18488 Adjust to new way of storing sizes. Check for size overflow bugs
18490 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18491 slightly wrong anyway, as it missed one instance of
18492 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18493 (refill_memory_reserve): Omit needless cast to size_t.
18494 (mark_object_loop_halt): Mark as externally visible.
18496 * xselect.c: Integer signedness and overflow fixes.
18497 (Fx_register_dnd_atom, x_handle_dnd_message):
18498 Use ptrdiff_t, not size_t, since we prefer signed.
18499 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18500 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18501 x_dnd_atoms_size and x_dnd_atoms_length.
18503 * doprnt.c: Prefer signed to unsigned when either works.
18505 * doprnt.c (doprnt):
18507 * xdisp.c (vmessage):
18508 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18509 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18510 prefer signed arithmetic to avoid comparison confusion.
18511 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18512 but is a bit tricky.
18514 Assume freestanding C89 headers, string.h, stdlib.h.
18515 * data.c, doprnt.c, floatfns.c, print.c:
18516 Include float.h unconditionally.
18517 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18518 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18519 * regex.c: Likewise for stddef.h, string.h.
18520 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18521 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18522 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18523 (STDC_HEADERS): Remove obsolete defines.
18524 * sysdep.c: Include limits.h unconditionally.
18526 Assume support for memcmp, memcpy, memmove, memset.
18527 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18528 * regex.c (memcmp, memcpy):
18529 Remove; we assume C89 now.
18531 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18532 (__malloc_safe_bcopy): Remove; no longer needed.
18534 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18535 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18536 well either way, and we prefer signed to unsigned.
18538 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18540 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18541 closes the connection while we're reading (bug#9182).
18543 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18545 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18546 are specified (Bug#9168).
18548 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18550 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18551 Found by GCC static checking and --with-wide-int on a 32-bit host.
18553 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18555 * xdisp.c (compute_display_string_pos): Fix logic of caching
18556 previous display string position. Initialize cached_prev_pos to
18557 -1. Fixes slow-down at the beginning of a buffer.
18559 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18561 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18562 for attrs[LFACE_FONTSET_INDEX].
18564 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18566 * xml.c (parse_region): Remove unused local
18567 that was recently introduced.
18569 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18571 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18572 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18574 * xdisp.c (move_it_in_display_line_to): Record the best matching
18575 position for TO_CHARPOS while scanning the line, and restore it on
18576 exit if none of the characters scanned was an exact match.
18577 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18578 when exact match is impossible due to invisible text, and the
18579 lines are truncated.
18581 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18583 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18586 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18588 Fix a significant slow-down of cursor motion with C-n, C-p,
18589 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18590 auto-repeat under bidi redisplay in fontified buffers.
18591 * xdisp.c (compute_stop_pos_backwards): New function.
18592 (next_element_from_buffer): Call compute_stop_pos_backwards to
18593 find a suitable prev_stop when we find ourselves before
18595 (reseat): Don't look for prev_stop, as that could mean a very long
18597 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18598 <cached_disp_overlay_modiff>: Cache for last found display string
18600 (compute_display_string_pos): Return the cached position if asked
18601 about the same buffer in the same area of character positions, and
18602 the buffer wasn't changed since the time the display string
18603 position was cached.
18605 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18607 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18608 is an integer, which is important for empty lines. (Bug#9149)
18610 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18612 * frame.c (Fmodify_frame_parameters): In tty case, update the
18613 default face if necessary (Bug#4238).
18615 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18617 * editfns.c (Fstring_to_char): No need to explain what a character
18618 is in the docstring (Bug#6576).
18620 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18622 * xml.c (parse_region): Make sure we always return a tree.
18624 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18626 * xml.c (parse_region): If a document contains only comments,
18629 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18631 * xml.c (make_dom): Return comments, too.
18633 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18636 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18637 and the surrounding thread.
18638 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18639 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18640 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18642 * s/openbsd.h (BROKEN_SIGIO): Define.
18643 * unexelf.c (unexec) [__OpenBSD__]:
18644 Don't update the .mdebug section of the Alpha COFF symbol table.
18646 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18648 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18651 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18653 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18654 This fixes some race conditions on the permissions of any newly
18657 * alloc.c (valid_pointer_p): Use pipe, not open.
18658 This fixes some permissions issues when debugging.
18660 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18661 If fchown fails to set both uid and gid, try to set just gid,
18662 as that is sometimes allowed. Adjust the file's mode to eliminate
18663 setuid or setgid bits that are inappropriate if fchown fails.
18665 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18667 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18668 to compare Lisp_Objects.
18669 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18670 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18671 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18673 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>

18683 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18684 This works around a problem with the previous change to Fcopy_file.
18685 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18686 and without this change, GCC might complain about discarding
18687 fchown's return value.
18689 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18691 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

18714 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18716 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18717 quotes the next character, and doesn't affect other longer
18718 sequences (bug#8935).

18721 `eval-buffer' and `eval-defun' that's affected by
18722 `lexical-binding' (bug#8460).

18732 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18733 (elsz): Now a signed constant, not a size_t var. We prefer signed
18734 types to unsigned, to avoid integer comparison confusion. Without
18735 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18736 "cannot optimize loop, the loop counter may overflow", a symptom
18738 * indent.c (Fvertical_motion): Mark locals as initialized.
18739 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18741 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

18768 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18769 original value of -1 will not work with bidi.)
18770 (compute_display_string_pos): First arg is now struct

18785 the iterator is before prev_stop.
18786 (init_iterator): Initialize bidi_p from the default value of

18828 iterator by calling bidi_pop_it same number of times.
18829 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18830 and we are bidi-iterating, don't decrement the iterator position;
18831 instead, set the first_elt flag in the bidi iterator, to produce
18833 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18834 (push_display_prop): xassert that we are iterating a buffer.

18838 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18839 correctly. Don't assume unibyte strings are not bidi-reordered.

19263 (clone_per_buffer_values): Don't assume that

19265 This isn't true in general, and it's particularly not true
19266 if Emacs is configured with --with-wide-int.
19267 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
19268 New macros, used in the buffer.c change.

19304 Random fixes. E.g., (random) never returned negative values.
19305 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19306 subseconds part to the entropy, as that's a bit more random.
19307 Prefer signed to unsigned, since the signedness doesn't matter and
19308 in general we prefer signed. When given a limit, use a
19309 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19310 latter isn't right if USE_2_TAGS_FOR_INTS.
19311 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19312 not 0..VALMASK. Don't discard "excess" bits that random () returns.

19316 * textprop.c (text_property_stickiness):
19317 Obey Vtext_property_default_nonsticky.

19324 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19325 This is more efficient than Ffile_directory_p and avoids a minor race.
19327 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
19329 * buffer.c (Foverlay_put): Say what the return value is
19332 * fileio.c (barf_or_query_if_file_exists): Check first if the file
19333 is a directory before asking whether to use the file name
19335 (barf_or_query_if_file_exists): Make the "File is a directory"
19336 error be more correct.
19338 * fns.c (Frequire): Remove the mention of the .gz files, since
19339 that's installation-specific, but keep the mention of

19344 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

19352 Qgnutls_bootprop_verify_error (which is no longer used).
19354 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
19355 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19356 Also (re)move comments that are misplaced or no longer relevant.

19383 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
19385 * lread.c (syms_of_lread): Mention single symbols defined by
19386 `defvar' or `defconst' (bug#7154).
19388 * fns.c (Frequire): Mention .el.gz files (bug#7314).
19389 (Frequire): Mention get-load-suffixes.

19457 * eval.c (struct backtrace): Simplify and port the data structure.
19458 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19459 signed bit field, as this assumption is not portable and it makes
19460 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19461 "char debug_on_exit : 1" as this is not portable either; instead,
19462 use the portable "unsigned int debug_on_exit : 1". Remove unused
19463 member evalargs. Remove obsolete comments about cc bombing out.
19465 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19553 * process.c (wait_reading_process_output): Bypass select if
19554 waiting for a cell while ignoring keyboard input, and input is
19555 pending. Suggested by Jan Djärv (Bug#8869).
19557 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
19559 Use gnulib's dup2 module instead of rolling our own.
19560 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
19562 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19564 * dispnew.c (scrolling_window): Before scrolling, turn off a

19627 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
19629 Integer and buffer overflow fixes (Bug#8873).
19631 * print.c (printchar, strout): Check for string overflow.
19632 (PRINTPREPARE, printchar, strout):
19633 Don't set size unless allocation succeeds.
19635 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19636 for sizes. Check for string overflow more accurately.
19637 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
19639 * macros.c: Integer and buffer overflow fixes.
19640 * keyboard.h (struct keyboard.kbd_macro_bufsize):
19641 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

19645 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
19647 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
19649 * lread.c: Integer overflow fixes.
19650 (read_integer): Radix is now EMACS_INT, not int,
19651 to improve quality of diagnostics for out-of-range radices.
19652 Calculate buffer size correctly for out-of-range radices.
19653 (read1): Check for integer overflow in radices, and in
19654 read-circle numbers.
19655 (read_escape): Avoid int overflow.
19656 (Fload, openp, read_buffer_size, read1)
19657 (substitute_object_recurse, read_vector, read_list, map_obarray):

19673 2011-06-22 Leo Liu <sdl.web@gmail.com>
19675 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
19676 Move to minibuffer.el.
19678 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19680 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19681 The following patches are for when GLYPH_DEBUG && !XASSERT.
19682 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19683 * dispnew.c (flush_stdout):
19684 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19685 Mark as externally visible.
19686 * dispnew.c (check_window_matrix_pointers): Now static.
19687 * dispnew.c (window_to_frame_vpos):
19688 * xfns.c (unwind_create_frame):

19690 * scroll.c (CHECK_BOUNDS):
19691 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19692 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19693 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19694 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19695 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19697 (debug_method_add): Use va_list and vsprintf rather than relying
19698 on undefined behavior with wrong number of arguments.
19699 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19700 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19701 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19702 since we're not interested in debugging glyphs with old libraries.
19703 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19704 GCC 4.6.0's static checking.
19706 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19708 Integer overflow and signedness fixes (Bug#8873).

19724 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19725 (.bitmaps_last, struct x_output.icon_bitmap):
19726 Use ptrdiff_t, not int, for bitmap indexes.
19727 (x_allocate_bitmap_record): Check for size overflow.
19728 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19730 Use ptrdiff_t, not int, for overlay counts.
19731 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19732 * editfns.c (overlays_around, get_pos_property):
19733 * textprop.c (get_char_property_and_overlay):
19734 * xdisp.c (next_overlay_change, note_mouse_highlight):
19735 * xfaces.c (face_at_buffer_position):
19736 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19737 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19738 (Fnext_overlay_change, Fprevious_overlay_change)
19739 (mouse_face_overlay_overlaps, Foverlays_in):
19740 Use ptrdiff_t, not int, for sizes.
19741 (overlays_at, overlays_in): Check for size-calculation overflow.
19743 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19745 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19746 (x_session_initialize): Do not assume string length fits in int.
19748 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19749 This is unlikely, but can occur if DPI is outlandish.
19751 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19752 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19754 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19755 * xrdb.c (magic_file_p, search_magic_path):
19756 Omit last arg SUFFIX; it was always 0. All callers changed.
19757 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19759 * xfont.c (xfont_match): Avoid need for strlen.
19761 * xfns.c: Don't assume strlen fits in int.

19764 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19765 not unsigned long, as we prefer signed integers. All callers changed.
19766 Detect integer overflow in repeat count.
19767 (message_dolog): Don't assume print length fits in 39 bytes.
19768 (display_mode_element): Don't assume strlen fits in int.
19770 * termcap.c: Don't assume sizes fit in int and never overflow.
19771 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19772 (gobble_line): Check for size-calculation overflow.
19774 * minibuf.c (Fread_buffer):
19775 * lread.c (intern, intern_c_string):

19782 * font.c: Don't assume string length fits in int.
19783 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19784 Use ptrdiff_t, not int.
19785 (font_intern_prop): Don't assume string length fits in int.
19786 Don't assume integer property fits in fixnum.
19787 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19789 * filelock.c: Fix some buffer overrun and integer overflow issues.
19790 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19791 Reformulate so as not to need the command string.
19792 Invoke gzip -cd rather than gunzip, as it's more portable.
19793 (lock_info_type, lock_file_1, lock_file):
19794 Don't assume pid_t and time_t fit in unsigned long.
19795 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19796 (current_lock_owner): Prefer signed type for sizes.
19797 Use memcpy, not strncpy, where memcpy is what is really wanted.
19798 Don't assume (via atoi) that time_t and pid_t fit in int.
19799 Check for time_t and/or pid_t out of range, e.g., via a network share.
19800 Don't alloca where an auto var works fine.
19802 * fileio.c: Fix some integer overflow issues.
19803 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19804 Don't assume string length fits in int.
19805 (directory_file_name): Don't assume string length fits in long.
19806 (make_temp_name): Don't assume pid fits in int, or that its print
19807 length is less than 20.
19809 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19811 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19813 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19815 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19816 We prefer signed integers, even for size calculations.
19818 * emacs.c: Don't assume string length fits in 'int'.
19819 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19820 (main): Don't invoke strlen when not needed.
19822 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

19825 * callproc.c (getenv_internal_1, getenv_internal)
19826 (Fgetenv_internal):
19827 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19829 * lread.c (invalid_syntax): Omit length argument.
19830 All uses changed. This doesn't fix a bug, but it simplifies the
19831 code away from its former Hollerith-constant appearance, and it's
19832 one less 'int' to worry about when looking at integer-overflow issues.
19833 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19835 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19836 This didn't break anything, but it didn't help either.
19837 It's confusing to put a bogus integer in a place where the actual
19838 value does not matter.
19839 (LIST_END_P): Remove unused macro and its bogus comment.
19840 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19842 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19843 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19845 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19846 We prefer signed types, and the value cannot exceed the EMACS_INT
19847 range anyway (because otherwise the length would not be representable).
19848 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19849 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19850 This avoids a GCC warning when WIDE_EMACS_INT.
19852 * indent.c (sane_tab_width): New function.
19853 (current_column, scan_for_column, Findent_to, position_indentation)
19854 (compute_motion): Use it. This is just for clarity.
19855 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19857 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

19861 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19863 * editfns.c, insdel.c:
19864 Omit unnecessary forward decls, to simplify future changes.
19866 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19868 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19870 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19871 Use much-faster test for byte-length change.
19872 Don't assume string byte-length fits in 'int'.
19873 Check that character arg fits in 'int'.
19874 (mapcar1): Declare byte as byte, for clarity.
19876 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19878 * fns.c (concat): Catch string overflow earlier.
19879 Do not rely on integer wraparound.
19881 * dispextern.h (struct it.overlay_strings_charpos)
19882 (struct it.selective): Now EMACS_INT, not int.
19883 * xdisp.c (forward_to_next_line_start)
19884 (back_to_previous_visible_line_start)
19885 (reseat_at_next_visible_line_start, next_element_from_buffer):
19886 Don't arbitrarily truncate the value of 'selective' to int.
19888 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19890 * composite.c: Don't truncate sizes to 'int'.
19891 (composition_gstring_p, composition_reseat_it)
19892 (composition_adjust_point): Use EMACS_INT, not int.
19893 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19894 not EMACS_UINT, for indexes.
19896 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19898 * buffer.c: Include <verify.h>.
19899 (struct sortvec.priority, struct sortstr.priority):
19900 Now EMACS_INT, not int.
19901 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19902 (struct sortstr.size, record_overlay_string)
19903 (struct sortstrlist.size, struct sortlist.used):
19904 Don't truncate size to int.
19905 (record_overlay_string): Check for size-calculation overflow.
19906 (init_buffer_once): Check at compile-time, not run-time.
19908 2011-06-22 Jim Meyering <meyering@redhat.com>
19910 Don't leak an XBM-image-sized buffer
19911 * image.c (xbm_load): Free the image buffer after using it.
19913 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19916 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19917 that Sun C diagnosed.
19918 * fns.c (secure_hash): Fix pointer signedness issue.
19919 * intervals.c (static_offset_intervals): New function.
19920 (offset_intervals): Use it.
19922 2011-06-21 Leo Liu <sdl.web@gmail.com>
19925 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19928 * fns.c (secure_hash): Rename from crypto_hash_function and change
19929 the first arg to accept symbols.
19930 (Fsecure_hash): New primitive.
19931 (syms_of_fns): New symbols.
19933 2011-06-20 Deniz Dogan <deniz@dogan.se>
19935 * process.c (Fset_process_buffer): Clarify return value in
19938 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19940 * dispnew.c (add_window_display_history): Use BVAR.
19942 * xdisp.c (debug_method_add): Use BVAR.
19943 (check_window_end, dump_glyph_matrix, dump_glyph)
19944 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19946 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19949 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19950 check till after the cache is created in init_frame_faces.
19952 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19954 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19956 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19958 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19959 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19960 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19962 Improve buffer-overflow checking (Bug#8873).
19963 * fileio.c (Finsert_file_contents):
19964 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19965 Remove the old (too-loose) buffer overflow checks.
19966 They weren't needed, since make_gap checks for buffer overflow.
19967 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19968 The old code merely checked for Emacs fixnum overflow, and relied
19969 on undefined (wraparound) behavior. The new code avoids undefined
19970 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19972 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19973 Tune. Don't use wider integers than needed. Don't use alloca.
19974 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19976 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19978 * insdel.c, lisp.h (buffer_overflow): New function.
19979 (insert_from_buffer_1, replace_range, replace_range_2):
19980 * insdel.c (make_gap_larger):
19981 * editfns.c (Finsert_char):
19982 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19984 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19986 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19988 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19990 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19991 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19993 * fileio.c: Don't assume EMACS_INT fits in off_t.
19994 (emacs_lseek): New static function.
19995 (Finsert_file_contents, Fwrite_region): Use it.
19996 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19998 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
20000 * fns.c: Don't overflow int when computing a list length.
20001 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
20002 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
20003 truncation on 64-bit hosts. Check for QUIT every
20004 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
20005 faster and is responsive enough.
20006 (Flength): Report an error instead of overflowing an integer.
20007 (Fsafe_length): Return a float if the value is not representable
20008 as a fixnum. This shouldn't happen except in contrived situations.
20009 (Fnthcdr, Fsort): Don't assume list length fits in int.
20010 (Fcopy_sequence): Don't assume vector length fits in int.
20012 * alloc.c: Check that resized vectors' lengths fit in fixnums.
20013 (header_size, word_size): New constants.
20014 (allocate_vectorlike): Don't check size overflow here.
20015 (allocate_vector): Check it here instead, since this is the only
20016 caller of allocate_vectorlike that could cause overflow.
20017 Check that the new vector's length is representable as a fixnum.
20019 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
20020 The previous code was bogus. For example, next_almost_prime (32)
20021 returned 39, which is undesirable as it is a multiple of 3; and
20022 next_almost_prime (24) returned 25, which is a multiple of 5 so
20023 why was the code bothering to check for multiples of 7?
20025 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
20027 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
20029 Variadic C functions now count arguments with ptrdiff_t.
20030 This partly undoes my 2011-03-30 change, which replaced int with size_t.
20031 Back then I didn't know that the Emacs coding style prefers signed int.
20032 Also, in the meantime I found a few more instances where arguments
20033 were being counted with int, which may truncate counts on 64-bit
20034 machines, or EMACS_INT, which may be unnecessarily wide.
20035 * lisp.h (struct Lisp_Subr.function.aMANY)
20036 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
20037 Arg counts are now ptrdiff_t, not size_t.
20038 All variadic functions and their callers changed accordingly.
20039 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
20040 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
20041 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
20042 * callint.c (Fcall_interactively): Check arg count for overflow,
20043 to avoid potential buffer overrun. Use signed char, not 'int',
20044 for 'varies' array, so that we needn't bother to check its size
20045 calculation for overflow.
20046 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
20047 * eval.c (apply_lambda):
20048 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
20049 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
20050 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
20052 * callint.c (Fcall_interactively): Don't use index var as event count.
20054 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
20055 * mem-limits.h (SIZE): Remove; no longer used.
20057 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
20059 Remove unnecessary casts.
20060 * xterm.c (x_term_init):
20061 * xfns.c (x_set_border_pixel):
20062 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
20063 These aren't needed now that we assume ANSI C.
20065 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
20066 It's more likely to cause problems (due to unsigned overflow)
20069 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
20071 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
20073 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
20075 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
20077 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
20079 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
20081 GLYPH_CODE_FACE returns EMACS_INT, not int.
20082 * dispextern.h (merge_faces):
20083 * xfaces.c (merge_faces):
20084 * xdisp.c (get_next_display_element, next_element_from_display_vector):
20085 Don't assume EMACS_INT fits in int.
20087 * character.h (CHAR_VALID_P): Remove unused parameter.
20088 * fontset.c, lisp.h, xdisp.c: All uses changed.
20090 * editfns.c (Ftranslate_region_internal): Omit redundant test.
20092 * fns.c (concat): Minor tuning based on overflow analysis.
20093 This doesn't fix any bugs. Use int to hold character, instead
20094 of constantly refetching from Emacs object. Use XFASTINT, not
20095 XINT, for value known to be a character. Don't bother comparing
20096 a single byte to 0400, as it's always less.
20098 * floatfns.c (Fexpt):
20099 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
20101 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
20104 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
20106 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
20107 Without this fix, on a 64-bit host (aset S 0 4294967386) would
20108 incorrectly succeed when S was a string, because 4294967386 was
20109 truncated before it was used.
20111 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
20112 Otherwise, an out-of-range integer could cause undefined behavior
20115 * composite.c: Use int, not EMACS_INT, for characters.
20116 (fill_gstring_body, composition_compute_stop_pos): Use int, not
20117 EMACS_INT, for values that are known to be in character range.
20118 This doesn't fix any bugs but is the usual style inside Emacs and
20119 may generate better code on 32-bit machines.
20121 Make sure a 64-bit char is never passed to ENCODE_CHAR.
20122 This is for reasons similar to the recent CHAR_STRING fix.
20123 * charset.c (Fencode_char): Check that character arg is actually
20124 a character. Pass an int to ENCODE_CHAR.
20125 * charset.h (ENCODE_CHAR): Verify that the character argument is no
20126 wider than 'int', as a compile-time check to prevent future regressions
20129 * character.c (char_string): Remove unnecessary casts.
20131 Make sure a 64-bit char is never passed to CHAR_STRING.
20132 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
20133 by silently ignoring the top 32 bits, allowing some values
20134 that were far too large to be valid characters.
20135 * character.h: Include <verify.h>.
20136 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
20137 arguments are no wider than unsigned, as a compile-time check
20138 to prevent future regressions in this area.
20140 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
20141 (Fsubst_char_in_region):
20143 * xdisp.c (decode_mode_spec_coding):
20144 Adjust to CHAR_STRING's new requirement.
20145 * editfns.c (Finsert_char, Fsubst_char_in_region):
20146 * fns.c (concat): Check that character args are actually
20147 characters. Without this test, these functions did the wrong
20148 thing with wildly out-of-range values on 64-bit hosts.
20150 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
20151 These casts should not be needed on 32-bit hosts, either.
20152 * keyboard.c (read_char):
20153 * lread.c (Fload): Remove casts to unsigned.
20155 * lisp.h (UNSIGNED_CMP): New macro.
20156 This fixes comparison bugs on 64-bit hosts.
20157 (ASCII_CHAR_P): Use it.
20158 * casefiddle.c (casify_object):
20159 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
20160 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
20161 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
20162 * dispextern.h (FACE_FROM_ID):
20163 * keyboard.c (read_char): Use UNSIGNED_CMP.
20165 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
20166 not to EMACS_INT, to avoid GCC warning.
20168 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
20170 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
20171 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
20172 isn't needed on 32-bit machines.
20174 * buffer.c (Fgenerate_new_buffer_name):
20175 Use EMACS_INT for count, not int.
20176 (advance_to_char_boundary): Return EMACS_INT, not int.
20178 * data.c (Qcompiled_function): Now static.
20180 * window.c (window_body_lines): Now static.
20182 * image.c (gif_load): Rename local to avoid shadowing.
20184 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
20185 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
20186 * alloc.c (make_save_value): Integer argument is now of type
20187 ptrdiff_t, not int.
20188 (mark_object): Use ptrdiff_t, not int.
20189 * lisp.h (pD): New macro.
20190 * print.c (print_object): Use it.
20192 * alloc.c: Use EMACS_INT, not int, to count objects.
20193 (total_conses, total_markers, total_symbols, total_vector_size)
20194 (total_free_conses, total_free_markers, total_free_symbols)
20195 (total_free_floats, total_floats, total_free_intervals)
20196 (total_intervals, total_strings, total_free_strings):
20197 Now EMACS_INT, not int. All uses changed.
20198 (Fgarbage_collect): Compute overall total using a double, so that
20199 integer overflow is less likely to be a problem. Check for overflow
20200 when converting back to an integer.
20201 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
20202 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
20203 These were 'int' variables that could overflow on 64-bit hosts;
20204 they were never used, so remove them instead of repairing them.
20205 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
20206 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
20207 Previously, this ceilinged at INT_MAX, but that doesn't work on
20209 (allocate_pseudovector): Don't use EMACS_INT when int would do.
20211 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
20212 (allocate_vectorlike): Check for ptrdiff_t overflow.
20213 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
20214 when a (possibly-narrower) signed value would do just as well.
20215 We prefer using signed arithmetic, to avoid comparison confusion.
20217 * alloc.c: Catch some string size overflows that we were missing.
20218 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20219 for convenience in STRING_BYTES_MAX.
20220 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
20221 The definition here is exact; the one in lisp.h was approximate.
20222 (allocate_string_data): Check for string overflow. This catches
20223 some instances we weren't catching before. Also, it catches
20224 size_t overflow on (unusual) hosts where SIZE_MAX <= min
20225 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
20226 and ptrdiff_t and EMACS_INT are both 64 bits.
20228 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20229 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
20230 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
20232 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
20234 * alloc.c (Fmake_string): Check for out-of-range init.
20236 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
20238 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
20240 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
20242 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
20243 xg_get_default_scrollbar_width.
20245 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
20246 (int_gtk_range_get_value): Move to the scroll bar part of the file.
20247 (style_changed_cb): Call update_theme_scrollbar_width and call
20248 x_set_scroll_bar_default_width and xg_frame_set_char_size for
20249 all frames (Bug#8505).
20250 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
20251 Call gtk_window_set_resizable if HAVE_GTK3.
20252 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
20253 and height if HAVE_GTK3 (Bug#8505).
20254 (scroll_bar_width_for_theme): New variable.
20255 (update_theme_scrollbar_width): New function.
20256 (xg_get_default_scrollbar_width): Move code to
20257 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
20258 (xg_initialize): Call update_theme_scrollbar_width.
20260 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
20262 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
20264 2011-06-12 Martin Rudalics <rudalics@gmx.at>
20266 * frame.c (make_frame): Call other_buffer_safely instead of
20269 * window.c (temp_output_buffer_show): Call display_buffer with
20270 second argument Vtemp_buffer_show_specifiers and reset latter
20271 immediately after the call.
20272 (Vtemp_buffer_show_specifiers): New variable.
20273 (auto_window_vscroll_p, next_screen_context_lines)
20274 (Vscroll_preserve_screen_position): Remove leading asterisks from
20277 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
20279 Fix minor problems found by GCC 4.6.0 static checking.
20280 * buffer.c (Qclone_number): Remove for now, as it's unused.
20281 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
20282 (record_buffer): Remove unused local.
20283 * frame.c (other_visible_frames, frame_buffer_list): Now static.
20284 (set_frame_buffer_list): Remove; unused.
20285 * frame.h (other_visible_frames): Remove decl.
20286 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
20287 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
20288 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
20290 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
20291 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
20292 Define only if HAVE_GPM.
20293 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
20294 (update_hints_inhibit): Remove; never set. All uses removed.
20295 * widgetprv.h (emacsFrameClassRec): Remove decl.
20296 * window.c (delete_deletable_window): Now returns void, since it
20297 wasn't returning anything.
20298 (compare_window_configurations): Remove unused locals.
20299 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
20300 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
20301 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
20302 the same widths as pointers. This follows up on the 2011-05-06 patch.
20303 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
20304 * xterm.h: Likewise.

20310 (LISP_H): Add lib/intprops.h.
20312 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
20314 * image.c (gif_load): Add animation frame delay to the metadata.
20315 (syms_of_image): Use DEFSYM. New symbol `delay'.
20317 2011-06-11 Martin Rudalics <rudalics@gmx.at>
20319 * window.c (delete_deletable_window): Re-add.
20320 (Fset_window_configuration): Rewrite to handle dead buffers and
20321 consequently deletable windows.
20322 (window_tree, Fwindow_tree): Remove. Supply functionality in
20324 (compare_window_configurations): Simplify code.
20326 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
20328 * image.c (imagemagick_load_image): Fix type mismatch.
20329 (Fimagemagick_types): Likewise.
20331 * window.h (replace_buffer_in_windows): Declare.
20333 2011-06-11 Martin Rudalics <rudalics@gmx.at>
20335 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
20336 Qclone_number. Remove external declaration of Qdelete_window.
20337 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
20339 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
20340 Run Qbuffer_list_update_hook if allowed.
20341 (Fother_buffer): Rewrite doc-string. Major rewrite for new
20342 buffer list implementation.
20343 (other_buffer_safely): New function.
20344 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
20345 calls to replace_buffer_in_windows and
20346 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
20348 (record_buffer): Inhibit quitting and rewrite using quittable
20349 functions. Run Qbuffer_list_update_hook if allowed.
20350 (Frecord_buffer, Funrecord_buffer): New functions.
20351 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
20352 Move switch-to-buffer to window.el.
20353 (bury-buffer): Move to window.el.
20354 (Vbuffer_list_update_hook): New variable.
20356 * lisp.h (other_buffer_safely): Add prototype in buffer.c
20359 * window.h (resize_frame_windows): Move up in code.
20360 (Fwindow_frame): Remove EXFUN.
20361 (replace_buffer_in_all_windows): Remove prototype.
20362 (replace_buffer_in_windows_safely): Add prototype.
20364 * window.c: Declare Qdelete_window static again. Move down
20365 declaration of select_count.
20366 (Fnext_window, Fprevious_window): Rewrite doc-strings.
20367 (Fother_window): Move to window.el.
20368 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
20369 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
20370 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
20372 (replace_buffer_in_windows): Implement by calling
20373 Qreplace_buffer_in_windows.
20374 (replace_buffer_in_all_windows): Remove with some functionality
20375 moved into replace_buffer_in_windows_safely.
20376 (replace_buffer_in_windows_safely): New function.
20377 (select_window_norecord, select_frame_norecord): Move in front
20378 of run_window_configuration_change_hook. Remove now obsolete
20380 (Fset_window_buffer): Rewrite doc-string.
20381 Call Qrecord_window_buffer.
20382 (keys_of_window): Move binding for other-window to window.el.
20384 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
20386 * dispextern.h (struct image): Replace data member, whose int_val
20387 and ptr_val fields were not used by anything, with a single
20390 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
20391 (gif_clear_image, gif_load, imagemagick_load_image)
20392 (gs_clear_image, gs_load): Callers changed.

20867 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20868 All callers changed. (Bug#8762)
20870 * gnutls.c: Use Emacs's memory allocators.
20871 Without this change, the gnutls library would invoke malloc etc.
20872 directly, which causes problems on non-SYNC_INPUT hosts, and which
20873 runs afoul of improving memory_full behavior. (Bug#8761)
20874 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20875 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20876 xfree instead of the default malloc, realloc, free.
20877 (Fgnutls_boot): No need to check for memory allocation failure,
20878 since xmalloc does that for us.
20880 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20881 * category.c (hash_get_category_set):
20882 * ccl.c (ccl_driver):
20883 * charset.c (Fdefine_charset_internal):
20884 * charset.h (struct charset.hash_index):

20886 (composition_gstring_put_cache):
20887 * composite.h (struct composition.hash_index):
20888 * dispextern.h (struct image.hash):
20889 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
20890 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

20894 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20895 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20896 * image.c (make_image, search_image_cache, lookup_image)
20897 (xpm_put_color_table_h):
20898 * lisp.h (struct Lisp_Hash_Table):
20899 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20900 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20901 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20902 * alloc.c (allocate_vectorlike):
20903 Check for overflow in vector size calculations.
20904 * ccl.c (ccl_driver):
20905 Check for overflow when converting EMACS_INT to int.
20906 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20907 need to be updated by these changes.
20908 * fns.c (make_hash_table, maybe_resize_hash_table):
20909 Check for integer overflow with large hash tables.
20910 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20911 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20912 (SXHASH_REDUCE): New macro.
20913 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20914 Use it instead of discarding useful hash info with large hash values.
20915 (sxhash_float): New function.
20916 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20917 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20918 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20919 Rewrite to use FIXNUM_BITS, as this simplifies things.
20920 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20921 Adjust signatures to match updated version of code.
20922 (consing_since_gc): Now EMACS_INT, since a single hash table can
20923 use more than INT_MAX bytes.
20925 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20927 Make it possible to build with GCC-4.6+ -O2 -flto.
20929 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20931 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20933 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20934 Call minibuffer-inactive-mode.
20936 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20938 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20939 Update dependencies.
20941 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20943 * data.c (init_data): Remove code for UTS, this system is not
20946 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20948 Don't force ./temacs to start in terminal mode.
20950 * frame.c (make_initial_frame): Initialize faces in all cases, not
20951 only when CANNOT_DUMP is defined.
20952 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20954 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20956 * dispnew.c (add_window_display_history): Use const for the string
20957 pointer. Remove declaration, not needed.
20959 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20961 Use 'inline', not 'INLINE'.
20962 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20963 * alloc.c, fontset.c (INLINE): Remove.
20964 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20965 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20966 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20967 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20968 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20970 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20972 Make it possible to run ./temacs.
20974 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20975 syms_of_callproc does the same thing. Remove test for
20976 "initialized", do it in the caller.
20977 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20979 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20981 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20982 (read_minibuf): Use get_minibuffer.
20983 (syms_of_minibuf): Use DEFSYM.
20984 (Qmetadata): New var.
20985 * data.c (Qbuffer): Don't make it static.
20986 (syms_of_data): Use DEFSYM.
20988 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20990 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20991 (CCL_CODE_MIN): New macro.
20993 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20995 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20997 * eval.c (Qdebug): Now static.
20998 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20999 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
21000 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
21002 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
21004 * image.c: Various fixes to ImageMagick code comments.
21005 (Fimagemagick_types): Doc fix.
21007 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
21009 Minor fixes prompted by GCC 4.6.0 warnings.
21011 * xselect.c (converted_selections, conversion_fail_tag): Now static.
21013 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
21014 (x_clipboard_manager_save_all): Move extern decl to ...
21015 * xterm.h: ... here, so that it can be checked for consistency.
21017 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
21019 * xselect.c (x_clipboard_manager_save_frame)
21020 (x_clipboard_manager_save_all): New functions.
21021 (Fx_clipboard_manager_save): Lisp function deleted.
21023 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
21024 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
21026 * xterm.h: Update prototype.
21028 2011-05-28 William Xu <william.xwl@gmail.com>
21030 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
21031 exiting (Bug#8239).
21033 2011-05-28 Jim Meyering <meyering@redhat.com>
21035 Avoid a sign-extension bug in crypto_hash_function.
21036 * fns.c (to_uchar): Define.
21037 (crypto_hash_function): Use it to convert some newly-signed
21038 variables to unsigned, to avoid sign-extension bugs. For example,
21039 without this change, (md5 "truc") would evaluate to
21040 45723a2aff78ff4fff7fff1114760e62 rather than the expected
21041 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
21042 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
21044 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21046 Integer overflow fixes.
21048 * dbusbind.c: Serial number integer overflow fixes.
21049 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
21050 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
21051 to hold a serial number that is too large for a fixnum.
21052 (Fdbus_method_return_internal, Fdbus_method_error_internal):
21053 Check for serial numbers out of range. Decode any serial number
21054 that was so large that it became a float. (Bug#8722)
21056 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
21057 (Fdbus_call_method, Fdbus_call_method_asynchronously):
21058 Use XFASTINT rather than XUINT when numbers are nonnegative.
21059 (xd_append_arg, Fdbus_method_return_internal):
21060 (Fdbus_method_error_internal): Likewise. Also, for unsigned
21061 arguments, check that Lisp number is nonnegative, rather than
21062 silently wrapping negative numbers around. (Bug#8722)
21063 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
21066 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
21068 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
21070 ccl: Add integer overflow checks.
21071 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
21072 (IN_INT_RANGE): New macros.
21073 (ccl_driver): Use them to check for integer overflow when
21074 decoding a CCL program. Many of the new checks are whether XINT (x)
21075 fits in int; it doesn't always, on 64-bit hosts. The new version
21076 doesn't catch all possible integer overflows, but it's an
21077 improvement. (Bug#8719)
21079 * alloc.c (make_event_array): Use XINT, not XUINT.
21080 There's no need for unsigned here.
21082 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
21083 This follows up to the 2011-05-06 change that substituted uintptr_t
21084 for EMACS_INT. This case wasn't caught back then.
21086 Rework Fformat to avoid integer overflow issues.
21087 * editfns.c: Include <float.h> unconditionally, as it's everywhere
21088 now (part of C89). Include <verify.h>.
21089 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
21090 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
21091 (Fformat): Avoid the prepass trying to compute sizes; it was only
21092 approximate and thus did not catch overflow reliably. Instead, walk
21093 through the format just once, formatting and computing sizes as we go,
21094 checking for integer overflow at every step, and allocating a larger
21095 buffer as needed. Keep track separately whether the format is
21096 multibyte. Keep only the most-recently calculated precision, rather
21097 than them all. Record whether each argument has been converted to
21098 string. Use EMACS_INT, not int, for byte and char and arg counts.
21099 Support field widths and precisions larger than INT_MAX. Avoid
21100 sprintf's undefined behavior with conversion specifications such as %#d
21101 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
21102 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
21103 formatting out-of-range floating point numbers with int
21104 formats. (Bug#8668)
21106 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
21108 * data.c: Avoid integer truncation in expressions involving floats.
21109 * data.c: Include <intprops.h>.
21110 (arith_driver): When there's an integer overflow in an expression
21111 involving floating point, convert the integers to floating point
21112 so that the resulting value does not suffer from catastrophic
21113 integer truncation. For example, on a 64-bit host (* 4
21114 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
21115 Do not rely on undefined behavior after integer overflow.
21117 merge count_size_as_multibyte, parse_str_to_multibyte
21118 * character.c, character.h (count_size_as_multibyte):
21119 Rename from parse_str_to_multibyte; all uses changed.
21120 Check for integer overflow.
21121 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
21122 since it's now a duplicate of the other. This is more of
21123 a character than a buffer op, so better that it's in character.c.
21124 * fns.c, print.c: Adjust to above changes.
21126 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
21128 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
21130 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21132 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21133 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
21134 (x_clipboard_manager_save): Now static.
21135 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
21137 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21138 (crypto_hash_function): Now static.
21139 Fix pointer signedness problems. Avoid unnecessary initializations.
21141 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
21143 * termhooks.h (Vselection_alist): Make it terminal-local.
21145 * terminal.c (create_terminal): Initialize it.
21147 * xselect.c: Support for clipboard managers.
21148 (Vselection_alist): Move to termhooks.h as terminal-local var.
21149 (LOCAL_SELECTION): New macro.
21150 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
21151 (symbol_to_x_atom): Remove gratuitous arg.
21152 (x_handle_selection_request, lisp_data_to_selection_data)
21153 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
21154 (x_own_selection, x_get_local_selection, x_convert_selection):
21155 New arg, specifying work frame. Use terminal-local Vselection_alist.
21156 (some_frame_on_display): Delete unused function.
21157 (Fx_own_selection_internal, Fx_get_selection_internal)
21158 (Fx_disown_selection_internal, Fx_selection_owner_p)
21159 (Fx_selection_exists_p): New optional frame arg.
21160 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
21161 (x_handle_selection_clear): Don't treat other terminals with the
21162 same keyboard specially. Use the terminal-local Vselection_alist.
21163 (x_clear_frame_selections): Use Frun_hook_with_args.
21165 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
21167 * xterm.h: Add support for those atoms.
21169 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
21171 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
21172 (converted_selections, conversion_fail_tag): New global variables.
21173 (x_selection_request_lisp_error): Free the above.
21174 (x_get_local_selection): Remove unnecessary code.
21175 (x_reply_selection_request): Args changed; handle arbitrary array
21176 of converted selections stored in converted_selections.
21177 Separate the XChangeProperty and SelectionNotify steps.
21178 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21179 (x_convert_selection): New function.
21180 (x_handle_selection_event): Simplify.
21181 (x_get_foreign_selection): Don't ignore incoming requests while
21182 waiting for an answer; this will fail when we implement
21183 SAVE_TARGETS, and seems unnecessary anyway.
21184 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21185 (Vx_sent_selection_functions): Doc fix.
21187 2011-05-26 Leo Liu <sdl.web@gmail.com>
21189 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21191 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21193 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21195 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21196 for fringe update if it has periodic bitmap.
21197 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21198 and fringe_bitmap_periodic_p.
21200 * fringe.c (get_fringe_bitmap_data): New function.
21201 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21202 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21203 row. Mark glyph row for fringe update if periodicity changed.
21205 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21206 for fringe update unless it has periodic bitmap.
21208 2011-05-25 Kenichi Handa <handa@m17n.org>
21210 * xdisp.c (get_next_display_element): Set correct it->face_id for

21226 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21227 Remove macros that are defined and never used.
21228 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21230 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21232 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21233 (Fx_get_selection_internal): Minor cleanup.

21259 report_file_error introduced by the change from 2011-05-07.
21261 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21263 * systime.h (Time): Define only if emacs is defined.
21264 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21265 where the include path doesn't have X11/X.h by default. See
21266 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21268 2011-05-20 Kenichi Handa <handa@m17n.org>
21270 * composite.c (find_automatic_composition): Fix previous change.
21272 2011-05-20 Glenn Morris <rgm@gnu.org>

21283 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21284 (lisp): Set the order to that of loadup.el.
21285 (shortlisp): Make it a copy of $lisp.
21286 (SOME_MACHINE_LISP): Remove.
21287 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21288 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21290 2011-05-18 Kenichi Handa <handa@m17n.org>
21292 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21293 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21294 (find_automatic_composition): Mostly rewrite for efficiency.
21296 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
21298 * makefile.w32-in: Update dependencies.
21300 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21302 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21303 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21305 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21307 Fix some integer overflow issues, such as string length overflow.
21309 * insdel.c (count_size_as_multibyte): Check for string overflow.
21311 * character.c (lisp_string_width): Check for string overflow.
21312 Use EMACS_INT, not int, for string indexes and lengths; in
21313 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21314 the resulting string length overflows an EMACS_INT; instead,
21315 report a string overflow if no precision given. When checking for
21316 precision exhaustion, use a check that cannot possibly have
21317 integer overflow. (Bug#8675)
21318 * character.h (lisp_string_width): Adjust to new signature.
21320 * alloc.c (string_overflow): New function.
21321 (Fmake_string): Use it. This doesn't change behavior, but saves
21322 a few bytes and will simplify future changes.
21323 * character.c (string_escape_byte8): Likewise.
21324 * lisp.h (string_overflow): New decl.
21326 Fixups, following up to the user-interface timestamp change.
21327 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21328 for UI timestamps, instead of unsigned long.
21329 * msdos.c (mouse_get_pos): Likewise.
21330 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21331 * w32gui.h (Time): Define by including "systime.h" rather than by
21332 declaring it ourselves. (Bug#8664)
21334 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21335 * image.c (clear_image_cache): Likewise.
21337 * term.c (term_mouse_position): Don't assume time_t wraparound.
21339 Be more systematic about user-interface timestamps.
21340 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21341 and sometimes 'EMACS_UINT', to represent these timestamps.
21342 This change causes it to use 'Time' uniformly, as that's what X uses.
21343 This makes the code easier to follow, and makes it easier to catch
21344 integer overflow bugs such as Bug#8664.
21345 * frame.c (Fmouse_position, Fmouse_pixel_position):
21346 Use Time, not unsigned long, for user-interface timestamps.
21347 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21348 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21349 * keyboard.h (last_event_timestamp): Likewise.
21350 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21351 * menu.h (xmenu_show): Likewise.
21352 * term.c (term_mouse_position): Likewise.
21353 * termhooks.h (struct input_event.timestamp): Likewise.
21354 (struct terminal.mouse_position_hook): Likewise.
21355 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21356 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21357 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21358 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21359 what it was before.
21360 * menu.h, termhooks.h: Include "systime.h", for Time.
21362 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21363 Don't assume that the difference between two unsigned long values
21364 can fit into an integer. At this point, we know button_down_time
21365 <= event->timestamp, so the difference must be nonnegative, so
21366 there's no need to cast the result if double-click-time is
21367 nonnegative, as it should be; check that it's nonnegative, just in
21368 case. This bug is triggered when events are more than 2**31 ms
21369 apart (about 25 days). (Bug#8664)
21371 * xselect.c (last_event_timestamp): Remove duplicate decl.
21372 (x_own_selection): Remove needless cast to unsigned long.
21374 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21375 that always fit in int. Use a sentinel instead of a counter, to
21376 avoid a temp and to allay GCC's concerns about possible int overflow.
21377 * frame.h (struct frame): Use int for menu_bar_items_used
21378 instead of EMACS_INT, since it always fits in int.
21380 * menu.c (grow_menu_items): Check for int overflow.
21382 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21384 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21385 Before, the code was not consistent. These values cannot exceed
21386 2**31 - 1 so there's no need to make them unsigned.
21387 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21388 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21389 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21391 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21393 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21394 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21395 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21396 presumably because the widths might not match.
21398 * window.c (size_window): Avoid needless test at loop start.
21400 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21402 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21404 2011-05-12 Drew Adams <drew.adams@oracle.com>
21406 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21408 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21410 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21411 `width' to `bar_area_x' and `bar_area_width', respectively.
21412 (x_scroll_run): Take account of fringe background extension.
21414 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21415 Rename local vars `left' and `width' to `bar_area_x' and
21416 `bar_area_width', respectively.
21417 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21418 background extension.
21420 2011-05-10 Jim Meyering <meyering@redhat.com>
21422 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21424 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21426 * image.c (Finit_image_library): Return t for built-in image types,
21427 like pbm and xbm. (Bug#8640)
21429 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21431 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21433 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21435 * w32console.c (Fset_screen_color): Doc fix.
21436 (Fget_screen_color): New function.
21437 (syms_of_ntterm): Defsubr it.
21439 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21440 unlink the temporary file if Fcall_process didn't create it in the
21442 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21443 child process will be redirected to a file specified with `:file'.
21444 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21445 cue to call_process_cleanup not to close that handle.
21447 2011-05-07 Ben Key <bkey76@gmail.com>
21449 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21450 one of two shell specific rules, either bootstrap-temacs-CMD or
21451 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21452 to the previous implementation of the bootstrap-temacs rule.
21453 The bootstrap-temacs-CMD rule is similar to the previous
21454 implementation of the bootstrap-temacs rule except that it
21455 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21458 These changes, along with some changes to nt/configure.bat,
21459 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21460 earlier fix to add support for --cflags and --ldflags options
21461 that include quotes so that it works whether make uses cmd or
21464 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21466 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21467 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21469 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21470 a string. Handle both cases.
21471 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21472 (Fdbus_register_method): Use Qinvalid_function.
21474 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21476 * makefile.w32-in: Update dependencies.
21477 (LISP_H): Add inttypes.h and stdin.h.
21478 (PROCESS_H): Add unistd.h.
21480 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21482 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21483 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21485 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21487 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21489 * term.c (vfatal): Remove stray call to va_end.
21490 It's not needed and the C Standard doesn't allow it here anyway.
21492 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21493 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21495 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21498 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21500 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21502 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21504 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21506 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21508 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21509 * charset.c (Fdefine_charset_internal): Don't initialize
21510 charset.code_space[15]. The value was garbage, on hosts with
21511 32-bit int (Bug#8600).
21513 * lread.c (read_integer): Be more consistent with string-to-number.
21514 Use string_to_number to do the actual conversion; this avoids
21515 rounding errors and fixes some other screwups. Without this fix,
21516 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21517 (digit_to_number): Move earlier, for benefit of read_integer.
21518 Return -1 if the digit is out of range for the base, -2 if it is
21519 not a digit in any supported base. (Bug#8602)
21521 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21523 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21524 to match comment at start of function. This also removes a
21525 GCC warning about overflow in a 32+64-bit port.
21527 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21529 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21530 Reported by Stefan Monnier in
21531 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21532 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21533 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21535 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21536 (EMACS_UINTPTR): Likewise, with uintptr_t.
21538 * lisp.h: Prefer 64-bit EMACS_INT if available.
21539 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21540 on 32-bit hosts that have 64-bit int, so that they can access
21542 However, temporarily disable this change unless the temporary
21543 symbol WIDE_EMACS_INT is defined.
21545 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21547 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21548 This removes an assumption that EMACS_INT and long are the same
21549 width as pointers. The assumption is true for Emacs porting targets
21550 now, but we want to make other targets possible.
21551 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21552 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21553 In the rest of the code, change types of integers that hold casted
21554 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21555 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21556 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21557 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21558 No need to cast type when ORing.
21559 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21560 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21561 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21562 assume EMACS_INT is the same width as char *.
21563 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21564 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21565 Remove no-longer-needed casts.
21566 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21567 (xg_tool_bar_help_callback, xg_make_tool_item):
21568 Use EMACS_INTPTR to hold an integer
21569 that will be cast to void *; this can avoid a GCC warning
21570 if EMACS_INT is not the same width as void *.
21571 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21572 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21573 (current_message_1, set_message_1):
21574 Use a local to convert to proper width without a cast.
21575 * xmenu.c (dialog_selection_callback): Likewise.
21577 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21578 Also, don't assume VALBITS / RAND_BITS is less than 5,
21579 and don't rely on undefined behavior when shifting a 1 left into
21581 * lisp.h (get_random): Change signature to match.
21583 * lread.c (hash_string): Use size_t, not int, for hash computation.
21584 Normally we prefer signed values; but hashing is special, because
21585 it's better to use unsigned division on hash table sizes so that
21586 the remainder is nonnegative. Also, size_t is the natural width
21587 for hashing into memory. The previous code used 'int', which doesn't
21588 retain enough info to hash well into very large tables.
21589 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21591 * dbusbind.c: Don't possibly lose pointer info when converting.
21592 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21593 Use XPNTR rather than XHASH, so that the high-order bits of
21594 the pointer aren't lost when converting through void *.
21596 * eval.c (Fautoload): Don't double-shift a pointer.
21598 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21600 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21602 * gnutls.c (DEF_GNUTLS_FN):
21603 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21605 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21607 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21610 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21612 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21613 New version that can reserve upto 2GB of heap space.
21615 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21617 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21619 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21621 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21622 `gnutls_certificate_set_x509_key_file'.
21624 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21626 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21627 Update dependencies.
21629 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21631 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21632 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21633 Remove unused parameter `fildes'.
21634 * process.c (read_process_output, send_process): Don't pass it.
21636 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21638 Fix previous change: the library cache is defined in w32.c.
21639 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21640 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21642 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21644 Implement dynamic loading of GnuTLS on Windows.
21646 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21647 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21648 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21651 * gnutls.c (Qgnutls_dll): Define.
21652 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21653 (gnutls_*): Declare function pointers.
21654 (init_gnutls_functions): New function to initialize function pointers.
21655 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21656 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21657 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21658 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21659 (emacs_gnutls_write, emacs_gnutls_read)
21660 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21661 (Fgnutls_available_p): New function.
21662 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21663 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21664 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21666 * image.c: Include w32.h.
21667 (Vimage_type_cache): Delete.
21668 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
21669 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21670 (w32_delayed_load): Move to w32.c.
21672 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21674 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21675 (w32_delayed_load): Move from image.c. When loading a library, record
21676 its filename in the :loaded-from property of the library id.
21677 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21678 Initialize and staticpro them.
21679 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21681 * process.c: Include lisp.h before w32.h, not after.
21682 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21683 instead of gnutls_record_check_pending.
21685 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21687 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21689 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21690 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21693 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21695 * xterm.c (x_set_frame_alpha): Do not set property on anything
21696 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21698 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21700 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21702 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21704 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21705 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21711 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
21712 (Qgnutls_bootprop_callbacks_verify): Make static.

21724 * sysdep.c (interruptible_wait_for_termination): New function
21725 which is like wait_for_termination, but allows keyboard
21728 * callproc.c (Fcall_process): Add (:file "file") as an option for
21730 (Fcall_process_region): Ditto.
21732 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21734 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21735 rather than `XVECTOR (FOO)->size'.
21737 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21738 inttypes.h, as a gnulib replacement is used if it not available in
21741 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21743 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21744 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21745 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21747 * coding.c (coding_alloc_by_realloc): Error out if destination
21748 will grow beyond MOST_POSITIVE_FIXNUM.
21749 (decode_coding_emacs_mule): Abort if there isn't enough place in
21750 charbuf for the composition carryover bytes. Reserve an extra
21751 space for up to 2 characters produced in a loop.
21752 (decode_coding_iso_2022): Abort if there isn't enough place in
21753 charbuf for the composition carryover bytes.
21755 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21757 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21758 aborting when %lld or %lll format is passed.
21759 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21760 %llo or %llx format is passed. (Bug#8545)
21762 * window.c (window_scroll_line_based): Use a marker instead of
21763 simple variables to record original value of point. (Bug#7952)
21765 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21766 produced by %s or %c overflows available buffer space. (Bug#8545)
21768 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21770 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21771 (SIZE_MAX): Move defn after all includes, as they might #define it.
21773 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21775 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21777 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21779 * keyboard.c (Qdelayed_warnings_hook): Define.
21780 (command_loop_1): Run `delayed-warnings-hook'
21781 if Vdelayed_warnings_list is non-nil.
21782 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21783 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21785 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21787 * doprnt.c (doprnt): Don't return value smaller than the buffer
21788 size if the message was truncated. (Bug#8545).
21790 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21792 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21793 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21795 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21797 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21799 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21801 * makefile.w32-in: Update dependencies.
21803 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21805 Improve `doprnt' and its usage. (Bug#8545)
21806 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21807 `format_end'. Remove support for %l as a conversion specifier.
21808 Don't use xrealloc. Improve diagnostics when the %l size modifier
21809 is used. Update the commentary.
21811 * eval.c (verror): Simplify calculation of size_t.
21813 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21816 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21818 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21821 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21823 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21824 This makes this file independent of the recent pseudovector change.
21826 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21828 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21830 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21831 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21832 Remove unused local.
21833 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21835 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21836 GCC 4.6.0 optimizes based on type-based alias analysis.
21837 For example, if b is of type struct buffer * and v of type struct
21838 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21839 != &v->size, and therefore "v->size = 1; b->size = 2; return
21840 v->size;" must therefore return 1. This assumption is incorrect
21841 for Emacs, since it type-puns struct Lisp_Vector * with many other
21842 types. To fix this problem, this patch adds a new type struct
21843 vectorlike_header that documents the constraints on layout of vectors
21844 and pseudovectors, and helps optimizing compilers not get fooled
21845 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21846 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21847 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21849 (XSETPVECTYPE): Rewrite in terms of new macro.
21850 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21851 This is a bit clearer, and further avoids the possibility of
21852 undesirable aliasing.
21853 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21854 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21855 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21856 since Lisp_Subr is a special case (no "next" field).
21857 (ASIZE): Now uses header.size rather than size.
21858 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21859 to avoid the hassle of writing XVECTOR (foo)->header.size.
21860 (struct vectorlike_header): New type.
21861 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21862 object, to help avoid aliasing.
21863 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21864 (SUBRP): Likewise, since Lisp_Subr is a special case.
21865 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21866 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21867 (struct Lisp_Hash_Table): Combine first two members into a single
21868 struct vectorlike_header member. All uses of "size" and "next" members
21869 changed to be "header.size" and "header.next".
21870 * buffer.h (struct buffer): Likewise.
21871 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21872 * frame.h (struct frame): Likewise.
21873 * process.h (struct Lisp_Process): Likewise.
21874 * termhooks.h (struct terminal): Likewise.
21875 * window.c (struct save_window_data, struct saved_window): Likewise.
21876 * window.h (struct window): Likewise.
21877 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21878 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21879 * buffer.c (init_buffer_once): Likewise.
21880 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21882 * process.c (Fformat_network_address): Use local var for size,
21885 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21887 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21888 * data.c (atof): Remove decl; no longer used or needed.
21889 (digit_to_number): Move to lread.c.
21890 (Fstring_to_number): Use new string_to_number function, to be
21891 consistent with how the Lisp reader treats infinities and NaNs.
21892 Do not assume that floating-point numbers represent EMACS_INT
21893 without losing information; this is not true on most 64-bit hosts.
21894 Avoid double-rounding errors, by insisting on integers when
21895 parsing non-base-10 numbers, as the documentation specifies.
21896 * lisp.h (string_to_number): New decl, replacing ...
21897 (isfloat_string): Remove.
21898 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21899 (read1): Do not accept +. and -. as integers; this
21900 appears to have been a coding error. Similarly, do not accept
21901 strings like +-1e0 as floating point numbers. Do not report
21902 overflow for integer overflows unless the base is not 10 which
21903 means we have no simple and reliable way to continue.
21904 Break out the floating-point parsing into a new
21905 function string_to_number, so that Fstring_to_number parses
21906 floating point numbers consistently with the Lisp reader.
21907 (digit_to_number): Move here from data.c. Make it static inline.
21908 (E_CHAR, EXP_INT): Remove, replacing with ...
21909 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21910 (string_to_number): New function, replacing isfloat_string.
21911 This function checks for valid syntax and produces the resulting
21912 Lisp float number too. Rework it so that string-to-number
21913 no longer mishandles examples like "1.0e+". Use strtoumax,
21914 so that overflow for non-base-10 numbers is reported only when
21915 there's no portable and simple way to convert to floating point.
21917 * textprop.c (set_text_properties_1): Rewrite for clarity,
21918 and to avoid GCC warning about integer overflow.
21920 * intervals.h (struct interval): Use EMACS_INT for members
21921 where EMACS_UINT might cause problems. See
21922 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21923 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21924 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21926 (offset_intervals): Tell GCC not to worry about length overflow
21927 when negating a negative length.
21929 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21930 (overrun_check_free): Likewise.
21932 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21933 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21936 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21937 (gnutls_make_error): Rename local to avoid shadowing.
21938 (gnutls_emacs_global_deinit): ifdef out; not used.
21939 (Fgnutls_boot): Use const for pointer to readonly storage.
21940 Comment out unused local. Fix pointer signedness problems.
21942 * lread.c (openp): Don't stuff size_t into an 'int'.
21943 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21944 about possible signed overflow.
21946 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21947 (GDK_KEY_g): Don't define if already defined.
21948 (xg_prepare_tooltip): Avoid pointer signedness problem.
21949 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21951 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21952 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21954 * xfns.c (Fx_window_property): Simplify a bit,
21955 to make a bit faster and to avoid GCC 4.6.0 warning.
21956 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21958 * fns.c (internal_equal): Don't assume size_t fits in int.
21960 * alloc.c (compact_small_strings): Tighten assertion a little.
21962 Replace pEd with more-general pI, and fix some printf arg casts.
21963 * lisp.h (pI): New macro, generalizing old pEd macro to other
21964 conversion specifiers. For example, use "...%"pI"d..." rather
21965 than "...%"pEd"...".
21966 (pEd): Remove. All uses replaced with similar uses of pI.
21967 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21968 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21969 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21970 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21971 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21972 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21973 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21975 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21976 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21977 * print.c (safe_debug_print, print_object): Likewise.
21978 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21980 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21981 avoiding the 0 flag, which is not portable.
21982 * process.c (Fmake_network_process): Use pI to avoid cast.
21983 * region-cache.c (pp_cache): Likewise.
21984 * xdisp.c (decode_mode_spec): Likewise.
21985 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21986 behavior on 64-bit hosts with printf arg.
21987 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21988 (x_stop_queuing_selection_requests): Likewise.
21989 (x_get_window_property): Don't truncate byte count to an 'int'
21992 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21993 here, since it parses constructs like leading '-' and spaces,
21994 which are not wanted; and it overflows with large numbers.
21995 Instead, simply match F[0-9]+, which is what is wanted anyway.
21997 * alloc.c: Remove unportable assumptions about struct layout.
21998 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21999 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
22000 (allocate_vectorlike, make_pure_vector): Use the new macros,
22001 plus offsetof, to remove unportable assumptions about struct layout.
22002 These assumptions hold on all porting targets that I know of, but
22003 they are not guaranteed, they're easy to remove, and removing them
22004 makes further changes easier.
22006 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
22007 This doesn't fix a bug but makes the code clearer.
22008 (string_overrun_cookie): Now const. Use initializers that
22009 don't formally overflow signed char, to avoid warnings.
22010 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
22011 can cause Emacs to crash when string overrun checking is enabled.
22012 (allocate_buffer): Don't assume sizeof (struct buffer) is a
22013 multiple of sizeof (EMACS_INT); it need not be, if
22014 alignof(EMACS_INT) < sizeof (EMACS_INT).
22015 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
22017 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
22019 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
22021 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
22023 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
22024 supposed to be handshaking. (Bug#8556)
22025 Reported by Paul Eggert <eggert@cs.ucla.edu>.
22027 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
22029 * lisp.h (Qdebug): List symbol.
22030 * eval.c (Qdebug): Restore global linkage.

22032 (handle_user_signal): Break into debugger when debug-on-event
22033 matches the current signal symbol.
22035 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
22037 * alloc.c (check_sblock, check_string_bytes)
22038 (check_string_free_list): Convert to standard C.
22040 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
22042 * w32.c (emacs_gnutls_push): Fix typo.
22044 2011-04-25 Eli Zaretskii <eliz@gnu.org>
22046 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
22047 "cast to pointer from integer of different size".
22049 Improve doprnt and its use in verror. (Bug#8545)
22050 * doprnt.c (doprnt): Document the set of format control sequences
22051 supported by the function. Use SAFE_ALLOCA instead of always
22054 * eval.c (verror): Don't limit the buffer size at size_max-1, that
22055 is one byte too soon. Don't use xrealloc; instead xfree and
22058 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
22060 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
22063 * gnutls.c: Renamed global_initialized to
22064 gnutls_global_initialized. Added internals for the
22065 :verify-hostname-error, :verify-error, and :verify-flags
22066 parameters of `gnutls-boot' and documented those parameters in the
22067 docstring. Start callback support.
22068 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
22069 unless a fatal error occurred. Call gnutls_alert_send_appropriate
22070 on error. Return error code.
22071 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
22072 (emacs_gnutls_read): Likewise.
22073 (Fgnutls_boot): Return handshake error code.
22074 (emacs_gnutls_handle_error): New function.
22075 (wsaerror_to_errno): Likewise.

22078 (emacs_gnutls_push): Likewise.
22080 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
22081 (emacs_gnutls_push): Likewise.
22083 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
22085 * process.c (wait_reading_process_output): Check if GnuTLS
22086 buffered some data internally if no FDs are set for TLS
22089 * makefile.w32-in (OBJ2): Add gnutls.$(O).
22090 (LIBS): Link to USER_LIBS.

22096 display_replaced_before_p argument into display_replaced_p, to
22097 make it consistent with the commentary. Fix typos in the
22100 * textprop.c (syms_of_textprop): Remove dead code.

22112 to changes in oldXMenu/XMenu.h from 2011-04-16.
22113 (struct XMenu): Declare `help_text' `const char **'.

22124 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
22126 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
22129 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
22130 changes in globals.h immediately force recompilation.
22131 (TAGS): Depend on $(CURDIR)/m/intel386.h and
22132 $(CURDIR)/s/ms-w32.h.

22137 <char-direction-table>: Deleted.
22139 2011-04-23 Eli Zaretskii <eliz@gnu.org>
22141 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
22142 * doprnt.c: Include limits.h.
22143 (SIZE_MAX): New macro.
22144 (doprnt): Return a size_t value. 2nd arg is now size_t.
22145 Many local variables are now size_t instead of int or unsigned.
22146 Improve overflow protection. Support `l' modifier for integer
22147 conversions. Support %l conversion. Don't assume an EMACS_INT
22148 argument for integer conversions and for %c.
22150 * lisp.h (doprnt): Restore prototype.
22152 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
22153 $(SRC)/character.h.
22155 * Makefile.in (base_obj): Add back doprnt.o.

22398 * process.c (send_process): Adjust to the new signatures of
22399 emacs_write and emacs_gnutls_write. Do not attempt to store

22623 * editfns.c, lisp.h (get_operating_system_release): Remove.
22624 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
22625 worth the hassle of breaking this out.
22627 * xterm.c: Make symbols static if they're not exported.
22628 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
22629 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

22729 * lisp.h: Remove these decls.
22731 * buffer.c (buffer_count): Remove unused var.
22733 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

22735 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
22736 * dispextern.h (bidi_dump_cached_states): Remove, since it's
22737 exported only to the debugger.

22740 * atimer.h (run_all_atimers): Remove; not exported.
22742 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
22743 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
22744 was inaccessible from Lisp.
22745 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
22746 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
22748 alloc.c: Import and export fewer symbols, and remove unused items.
22749 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
22751 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22752 it's not optimized away by whole-program optimization.
22753 (message_enable_multibyte, free_misc): Remove.
22754 (catchlist, handlerlist, mark_backtrace):
22755 Declare only if BYTE_MARK_STACK.

22764 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
22765 (mark_backtrace): Define only if BYTE_MARK_STACK.
22766 * xdisp.c (message_enable_multibyte): Now static.
22768 Declare Lisp_Object Q* variables to be 'static' if not exported.
22769 This makes it easier for human readers (and static analyzers)
22770 to see whether these variables are used from other modules.
22771 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
22772 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
22773 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

22781 Remove decls of unexported vars.
22782 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22784 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22786 Make Emacs functions such as Fatom 'static' by default.
22787 This makes it easier for human readers (and static analyzers)
22788 to see whether these functions can be called from other modules.
22789 DEFUN now defines a static function. To make the function external
22790 so that it can be used in other C modules, use the new macro DEFUE.
22791 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22792 (Finit_image_library):
22793 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22794 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22795 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22796 Remove decls, since these functions are now static.
22797 (Funintern, Fget_internal_run_time): New decls, since these functions
22798 were already external.
22800 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22801 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

22807 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22808 Mark functions with DEFUE instead of DEFUN,
22809 if they are used in other modules.
22810 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22811 decls for now-static functions.
22812 * buffer.h (Fdelete_overlay): Remove decl.
22813 * callproc.c (Fgetenv_internal): Mark as internal.
22814 * composite.c (Fremove_list_of_text_properties): Remove decl.

22821 * fileio.c (Fmake_symbolic_link): New forward static decl.
22822 * image.c (Finit_image_library): New forward static decl.
22823 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22824 * intervals.h (Fprevious_property_change):
22825 (Fremove_list_of_text_properties): Remove decls.
22826 * keyboard.c (Fthis_command_keys): Remove decl.
22827 (Fcommand_execute): New forward static decl.

22843 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22845 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22848 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22850 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22851 when at ZV. (Bug#8487)
22853 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22855 * charset.c (Fclear_charset_maps): Use xfree instead of free.

22859 * termcap.c (tgetent): Likewise.
22860 * xfns.c (x_default_font_parameter): Likewise.
22861 * xsettings.c (read_and_apply_settings): Likewise.
22863 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22864 (overrun_check_free): Protoize.
22866 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22868 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22869 since callers should never pass a negative size.
22870 Change the signature to match that of plain 'read' and 'write'; see
22871 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22872 * lisp.h: Update prototypes of emacs_write and emacs_read.
22874 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22876 * xdisp.c (redisplay_window): Don't try to determine the character
22877 position of the scroll margin if the window start point w->startp
22878 is outside the buffer's accessible region. (Bug#8468)
22880 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22882 Fix write-region and its subroutines for buffers > 2GB.
22883 * fileio.c (a_write, e_write): Modify declaration of arguments and
22884 local variables to support buffers larger than 2GB.
22885 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22887 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22888 argument, local variables, and return value.
22890 * lisp.h: Update prototypes of emacs_write and emacs_read.
22892 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22894 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22896 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22898 Fix more problems found by GCC 4.6.0's static checks.
22900 * xdisp.c (vmessage): Use a better test for character truncation.
22902 * charset.c (load_charset_map): <, not <=, for optimization,
22903 and to avoid potential problems with integer overflow.
22904 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22905 * casetab.c (set_identity, shuffle): Likewise.
22906 * editfns.c (Fformat): Likewise.
22907 * syntax.c (skip_chars): Likewise.
22909 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22910 This also lets GCC 4.6.0 generate slightly better loop code.
22912 * callint.c (Fcall_interactively): <, not <=, for optimization.
22913 (Fcall_interactively): Count the number of arguments produced,
22914 not the number of arguments given. This is simpler and lets GCC
22915 4.6.0 generate slightly better code.
22917 * ftfont.c: Distingish more carefully between FcChar8 and char.
22918 The previous code passed unsigned char * to a functions like
22919 strlen and xstrcasecmp that expect char *, which does not
22920 conform to the C standard.
22921 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22922 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22923 char * when the C standard requires it.
22925 * keyboard.c (read_char): Remove unused var.
22927 * eval.c: Port to Windows vsnprintf (Bug#8435).
22928 Include <limits.h>.
22929 (SIZE_MAX): Define if the headers do not.
22930 (verror): Do not give up if vsnprintf returns a negative count.
22931 Instead, grow the buffer. This ports to Windows vsnprintf, which
22932 does not conform to C99. Problem reported by Eli Zaretskii.
22933 Also, simplify the allocation scheme, by avoiding the need for
22934 calling realloc, and removing the ALLOCATED variable.
22936 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22938 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22939 But keep the doprint source code for now, as we might revamp it
22940 and use it again (Bug#8435).
22941 * lisp.h (doprnt): Remove.
22942 * Makefile.in (base_obj): Remove doprnt.o.
22943 * deps.mk (doprnt.o): Remove.
22945 error: Print 32- and 64-bit integers portably (Bug#8435).
22946 Without this change, on typical 64-bit hosts error ("...%d...", N)
22947 was used to print both 32- and 64-bit integers N, which relied on
22948 undefined behavior.
22949 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22950 * lisp.h (error, verror): Mark as printf-like functions.
22951 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22952 Report overflow in size calculations when allocating printf buffer.
22953 Do not truncate output string at its first null byte.
22954 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22955 Truncate the output at a character boundary, since vsnprintf does not
22957 * charset.c (check_iso_charset_parameter): Convert internal
22958 character to string before calling 'error', since %c now has the
22960 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22961 overflow when computing char to be passed to 'error'. Do not
22962 pass Lisp_Object to 'error'; pass the integer instead.
22963 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22964 formatted with plain %d.
22966 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22968 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22970 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22972 * xterm.c (x_catch_errors): Remove duplicate declaration.
22974 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22976 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22978 2011-04-10 Jim Meyering <meyering@redhat.com>
22980 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22981 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22982 return ssize_t not "int", and use size_t as the buffer length.
22983 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22984 * gnutls.h: Update declarations.
22985 * process.c (read_process_output): Use ssize_t, to match.
22986 (send_process): Likewise.
22988 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22990 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22992 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22994 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22995 Use unsigned char, to match FcChar8 type definition.
22997 * xterm.c (handle_one_xevent):
22998 * xmenu.c (create_and_show_popup_menu):
22999 * xselect.c (x_decline_selection_request)
23000 (x_reply_selection_request): Avoid type-punned deref of X events.
23002 2011-04-09 Eli Zaretskii <eliz@gnu.org>
23004 Fix some uses of `int' instead of EMACS_INT.
23005 * search.c (string_match_1, fast_string_match)
23006 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
23007 (scan_buffer, find_next_newline_no_quit)
23008 (find_before_next_newline, search_command, Freplace_match)
23009 (Fmatch_data): Make some `int' variables be EMACS_INT.
23011 * xdisp.c (display_count_lines): 3rd argument and return value now
23012 EMACS_INT. All callers changed.
23013 (pint2hrstr): Last argument is now EMACS_INT.
23015 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
23016 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
23017 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

23020 (decode_coding_ccl, decode_coding_charset)
23021 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
23022 (decode_coding_iso_2022, decode_coding_emacs_mule)
23023 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
23024 <char_offset, last_offset>: Declare EMACS_INT.

23055 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
23057 * keyboard.c (read_char): Call Lisp function help-form-show,
23058 instead of using internal_with_output_to_temp_buffer.
23059 (Qhelp_form_show): New var.
23060 (syms_of_keyboard): Use DEFSYM macro.
23062 * print.c (internal_with_output_to_temp_buffer): Function deleted.

23077 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
23079 Fix more problems found by GCC 4.6.0's static checks.
23081 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
23083 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
23085 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
23087 * xdisp.c (vmessage): Mark as a printf-like function.
23089 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

23096 to system-supplied API.
23098 * eval.c (Fsignal): Remove excess argument to 'fatal'.
23100 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
23101 This avoids several warnings with gcc -Wstrict-overflow.
23102 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
23103 directly, rather than having caller test rule sign. This avoids
23104 some unnecessary tests.
23105 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
23106 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
23107 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
23109 * xfont.c (xfont_text_extents): Remove var that was set but not used.
23110 (xfont_open): Avoid unnecessary tests.
23112 * composite.c (composition_gstring_put_cache): Use unsigned integer.
23114 * composite.h, composite.c (composition_gstring_put_cache):
23115 Use EMACS_INT, not int, for length.
23117 * composite.h (COMPOSITION_DECODE_REFS): New macro,
23118 breaking out part of COMPOSITION_DECODE_RULE.
23119 (COMPOSITION_DECODE_RULE): Use it.
23120 * composite.c (get_composition_id): Remove unused local vars,
23121 by using the new macro.
23123 * textprop.c (set_text_properties_1): Change while to do-while,
23124 since the condition is always true at first.
23126 * intervals.c (graft_intervals_into_buffer): Mark var as used.
23127 (interval_deletion_adjustment): Return unsigned value.
23130 * process.c (list_processes_1, create_pty, read_process_output):
23131 (exec_sentinel): Remove vars that were set but not used.
23132 (create_pty): Remove unnecessary "volatile"s.
23133 (Fnetwork_interface_info): Avoid possibility of int overflow.
23134 (read_process_output): Do adaptive read buffering even if carryover.
23135 (read_process_output): Simplify nbytes computation if buffered.
23137 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
23139 * syntax.c (scan_words): Remove var that was set but not used.
23140 (update_syntax_table): Use unsigned instead of int.
23142 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

23144 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
23146 * print.c (print_error_message): Avoid int overflow.
23148 * font.c (font_list_entities): Redo for clarity,
23149 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
23151 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
23152 (font_score): Avoid potential overflow in diff calculation.
23154 * fns.c (substring_both): Remove var that is set but not used.
23155 (sxhash): Redo loop for clarity and to avoid wraparound warning.
23157 * eval.c (funcall_lambda): Rename local to avoid shadowing.
23159 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
23160 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
23161 can always succeed if overflow has undefined behavior.
23163 * search.c (boyer_moore, wordify): Remove vars set but not used.
23164 (wordify): Omit three unnecessary tests.
23166 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
23167 All callers changed. This avoids the need for an unused var.
23169 * casefiddle.c (casify_region): Remove var that is set but not used.
23171 * dired.c (file_name_completion): Remove var that is set but not used.
23173 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23175 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23176 (Finsert_file_contents): Remove unnecessary code checking fd.
23178 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23179 Check for integer overflow on size calculations.
23181 * buffer.c (Fprevious_overlay_change): Remove var that is set
23184 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23185 Remove vars that are set but not used.
23186 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23187 (timer_check_2): Mark vars as initialized.
23189 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23191 * image.c (lookup_image): Remove var that is set but not used.
23192 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23194 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23195 that are set but not used.
23197 * xfns.c (make_invisible_cursor): Don't return garbage
23198 if XCreateBitmapFromData fails (Bug#8410).
23200 * xselect.c (x_get_local_selection, x_handle_property_notify):
23201 Remove vars that are set but not used.
23203 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
23204 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
23206 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
23207 Remove var that is set but not used.
23208 (scroll_bar_windows_size): Now size_t, not int.
23209 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23210 Check for overflow.
23212 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23213 (map_tty_color) [!defined MSDOS]: Likewise.
23215 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23217 * coding.c: Remove vars that are set but not used.
23218 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
23219 All callers changed.
23220 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
23221 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
23222 (decode_coding_charset): Remove vars that are set but not used.
23224 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
23225 that is set but not used.
23227 * print.c (print_object): Remove var that is set but not used.
23229 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23230 The gnulib version avoids calling malloc in the usual case,
23231 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23232 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23233 * filelock.c (current_lock_owner): Likewise.
23234 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23235 * sysdep.c: Include allocator.h, careadlinkat.h.
23236 (emacs_no_realloc_allocator): New static constant.
23237 (emacs_readlink): New function.
23238 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23239 ../lib/careadlinkat.h.
23241 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23243 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
23244 first non-nil return value).
23246 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
23248 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
23249 if not defined (Bug#8403).
23251 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23253 * xdisp.c (display_count_lines): Remove parameter `start',
23254 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23255 (get_char_face_and_encoding): Remove parameter `multibyte_p',
23256 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

23258 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
23259 and thereabouts. All callers changed.
23260 (get_per_char_metric): Remove parameter `f', unused since
23261 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
23263 2011-04-02 Jim Meyering <meyering@redhat.com>
23265 do not dereference NULL upon failed strdup
23266 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23267 (ns_get_family): Likewise.
23269 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23271 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23273 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23275 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23278 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23280 Add lexical binding.
23282 * window.c (Ftemp_output_buffer_show): New fun.
23283 (Fsave_window_excursion):
23284 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
23286 * lread.c (lisp_file_lexically_bound_p): New function.
23287 (Fload): Bind Qlexical_binding.
23288 (readevalloop): Remove `evalfun' arg.
23289 Bind Qinternal_interpreter_environment.
23290 (Feval_buffer): Bind Qlexical_binding.
23291 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23293 (syms_of_lread): Declare `lexical-binding'.
23295 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23297 * keyboard.c (eval_dyn): New fun.
23298 (menu_item_eval_property): Use it.
23300 * image.c (parse_image_spec): Use Ffunctionp.
23302 * fns.c (concat, mapcar1): Accept byte-code-functions.
23304 * eval.c (Fsetq): Handle lexical vars.
23305 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23306 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23307 (FletX, Flet): Obey lexical binding.
23308 (Fcommandp): Handle closures.
23309 (Feval): New `lexical' arg.
23310 (eval_sub): New function extracted from Feval. Use it almost
23311 everywhere where Feval was used. Look up vars in lexical env.
23313 (Ffunctionp): Move from subr.el.
23314 (Ffuncall): Handle closures.
23315 (apply_lambda): Remove `eval_flags'.
23316 (funcall_lambda): Handle closures and new byte-code-functions.
23317 (Fspecial_variable_p): New function.
23318 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23319 but without exporting it to Lisp.
23321 * doc.c (Fdocumentation, store_function_docstring):
23322 * data.c (Finteractive_form): Handle closures.
23324 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23327 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23329 (exec_byte_code): New function extracted from Fbyte_code to handle new
23330 calling convention for byte-code-functions. Add new byte-codes.
23332 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
23334 * alloc.c (Fmake_symbol): Init new `declared_special' field.
23336 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23338 * xdisp.c (redisplay_internal): Fix prototype.
23340 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23342 * xdisp.c (SCROLL_LIMIT): New macro.
23343 (try_scrolling): Use it when setting scroll_limit.
23344 Limit scrolling to 100 screen lines.
23345 (redisplay_window): Even when falling back on "recentering",
23346 position point in the window according to scroll-conservatively,
23347 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23349 (try_scrolling): When point is above the window, allow searching
23350 as far as scroll_max, or one screenful, to compute vertical
23351 distance from PT to the scroll margin position. This prevents
23352 try_scrolling from unnecessarily failing when
23353 scroll-conservatively is set to a value slightly larger than the
23354 window height. Clean up the case of PT below the margin at bottom
23355 of window: scroll_max can no longer be INT_MAX. When aggressive
23356 scrolling is in use, don't let point enter the opposite scroll
23357 margin as result of the scroll.
23358 (syms_of_xdisp) <scroll-conservatively>: Document the
23359 threshold of 100 lines for never-recentering scrolling.
23361 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23363 * dispextern.h (move_it_by_lines):
23364 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
23365 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
23366 (message_log_check_duplicate): Remove parameters `prev_bol' and
23367 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23368 (redisplay_internal): Remove parameter `preserve_echo_area',
23369 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23371 * indent.c (Fvertical_motion):
23372 * window.c (window_scroll_pixel_based, Frecenter):
23373 Don't pass `need_y_p' to `move_it_by_lines'.
23375 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23377 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23378 steal a few bits to be more compact.
23379 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23380 Remove unneeded casts.
23382 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23384 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23386 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23387 binding" message (bug#7967).
23389 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23391 Fix more problems found by GCC 4.6.0's static checks.
23393 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23394 Remove unused local var.
23396 * editfns.c (Fmessage_box): Remove unused local var.
23398 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23399 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23400 Omit unused local vars.
23401 * window.c (shrink_windows): Omit unused local var.
23402 * menu.c (digest_single_submenu): Omit unused local var.
23403 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23404 Omit unused local var.
23406 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23407 Don't assume string length fits in int.
23408 (keyremap_step, read_key_sequence): Use size_t for sizes.
23409 (read_key_sequence): Don't check last_real_key_start redundantly.
23411 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
23412 instead of alloca (Bug#8344).
23414 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23415 (Fbacktrace_frame): Don't assume nframes fits in int.
23417 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
23419 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
23422 * term.c (produce_glyphless_glyph): Remove unnecessary test.
23424 * cm.c (calccost): Turn while-do into do-while, for clarity.
23426 * keyboard.c (syms_of_keyboard): Use the same style as later
23427 in this function when indexing through an array. This also
23428 works around GCC bug 48267.
23430 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23432 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23434 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23435 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23437 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23438 This avoids undefined behavior on integer overflow, and is a bit
23439 more convenient anyway since it is compared to a size_t variable.
23441 Variadic C functions now count arguments with size_t, not int.
23442 This avoids an unnecessary limitation on 64-bit machines, which
23443 caused (substring ...) to crash on large vectors (Bug#8344).
23444 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
23445 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
23446 All variadic functions and their callers changed accordingly.

23453 * fns.c (concat): Likewise.
23454 * frame.c (x_set_frame_parameters): Likewise.
23455 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23456 0 if not found, not -1. All callers changed.
23458 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23459 (stack_copy_size): Now size_t, not int.
23460 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23462 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
23464 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
23465 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
23466 All callers changed.
23468 * lisp.h (multibyte_char_to_unibyte):
23469 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
23470 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
23471 * character.h (CHAR_TO_BYTE8):
23472 * cmds.c (internal_self_insert):
23473 * editfns.c (general_insert_function):
23474 * keymap.c (push_key_description):
23475 * search.c (Freplace_match):
23476 * xdisp.c (message_dolog, set_message_1): All callers changed.
23478 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
23480 * keyboard.c (safe_run_hook_funcall): New function.
23481 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23482 don't set the hook to nil, but remove the offending function instead.
23483 (Qcommand_hook_internal): Remove, unused.
23484 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define

23666 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23668 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23669 unconditionally since it does the check itself.
23671 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23673 Fix more problems found by GCC 4.5.2's static checks.
23675 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23676 the first time through the loop, since we know p0 < p1 then.
23677 This also avoids a gcc -Wstrict-overflow warning.
23679 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23680 leading to a memory leak, possible in functions like
23681 load_charset_map_from_file that can allocate an unbounded number
23682 of objects (Bug#8318).
23684 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23685 that could (at least in theory) be that large.
23687 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23688 This is less likely to overflow, and avoids undefined behavior if
23689 overflow does occur. All callers changed. Use strtoul to scan
23690 for the unsigned long integer.
23691 (pint2hrstr): Simplify and tune code slightly.

23707 * process.c (Fmake_network_process): Use socklen_t, not int,
23708 where POSIX says socklen_t is required in portable programs.
23709 This fixes a porting bug on hosts like 64-bit HP-UX, where
23710 socklen_t is wider than int (Bug#8277).
23711 (Fmake_network_process, server_accept_connection):
23712 (wait_reading_process_output, read_process_output):

23725 Make tparam.h and terminfo.c consistent.
23726 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23727 Include tparam.h instead, since it declares them.
23728 * cm.h (PC): Remove extern decl; tparam.h now does this.
23729 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23730 * terminfo.c: Include tparam.h, to check interfaces.
23731 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23732 (tparam): Adjust signature to match interface in tparam.h;
23733 this removes some undefined behavior. Check that outstring and len
23734 are zero, which they always are with Emacs.
23735 * tparam.h (PC, BC, UP): New extern decls.
23737 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23738 (xftfont_open): Rename locals to avoid shadowing.

23756 (composition_update_it): Mark var as initialized.
23757 (find_automatic_composition): Mark vars as initialized,
23758 with a FIXME (Bug#8290).

23777 Fix pointer signedness.
23778 (alsa_choose_format): Remove unused local var.
23779 (wav_play): Initialize a variable to 0, to prevent undefined
23780 behavior (Bug#8278).
23782 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23784 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23786 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23787 clobbering (Bug#8298).
23788 * sysdep.c (sys_subshell): Likewise.
23789 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23791 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23792 This should get cleaned up, so that child_setup has the
23793 same signature on all platforms.
23795 * callproc.c (call_process_cleanup): Now static.
23796 (relocate_fd): Rename locals to avoid shadowing.
23798 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23800 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23801 not to be necessary, and produces flickering.
23803 2011-03-20 Glenn Morris <rgm@gnu.org>
23805 * config.in: Remove file.
23807 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

23857 n rather than nn, a way that does not involve shadowing.
23858 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23860 * deps.mk (unexalpha.o): Remove; unused.

23939 * data.c (Findirect_variable): Name an expression, to avoid
23940 gcc -Wbad-function-cast warning.
23941 (default_value, arithcompare, arith_driver, arith_error): Now static.

23955 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23956 (GC_STRING_CHARS): Remove; not used.
23957 (Fmemory_limit): Cast sbrk's returned value to char *.
23959 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23960 avoids undefined behavior in theory.
23962 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23964 Use functions, not macros, for up- and down-casing (Bug#8254).
23965 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23966 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23967 to use the following functions instead of these macros.
23968 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23969 EMACS_INT, since callers assume the returned value fits in int.
23970 (upcase1): Likewise, for UPCASE_TABLE.
23971 (uppercasep, lowercasep, upcase): New static inline functions.
23972 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23973 the race-condition problem in the old DOWNCASE.
23975 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
23976 Rename locals to avoid shadowing.
23977 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
23978 (regex_compile, re_search_2, re_match_2_internal):
23979 Remove unused local vars.

23981 which gcc can warn about.
23982 (regex_compile, re_match_2_internal): Mark locals as initialized.
23983 (RETALLOC_IF): Define only if needed.
23984 (WORDCHAR_P): Likewise. This one is never needed, but is used
23985 only in a comment talking about a compiler bug, so put inside
23986 the #if 0 of that comment.
23987 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23988 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23991 * search.c (boyer_moore): Rename locals to avoid shadowing.
23992 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

24014 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
24015 New macros, so that the caller can use some names other than
24016 gcpro1, gcpro2, etc.
24017 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
24019 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
24020 argument, for consistency with GCPRO2_VAR, etc: it is now the
24021 prefix of the variable, not the variable itself. All uses
24023 * dired.c (directory_files_internal, file_name_completion):
24024 Rename locals to avoid shadowing.
24026 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
24027 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
24028 dired.c's scmp function, had undefined behavior.
24029 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
24030 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
24031 * buffer.h: ... to here, because these macros use current_buffer,
24032 and the new implementation with inline functions needs to have
24033 current_buffer in scope now, rather than later when the macros
24035 (downcase, upcase1): New static inline functions.
24036 (DOWNCASE, UPCASE1): Reimplement using these functions.
24037 This avoids undefined behavior in expressions like
24038 DOWNCASE (x) == DOWNCASE (y), which previously suffered
24039 from race conditions in accessing the global variables
24040 case_temp1 and case_temp2.
24041 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
24042 * lisp.h (case_temp1, case_temp2): Remove their decls.
24043 * character.h (ASCII_CHAR_P): Move from here ...
24044 * lisp.h: ... to here, so that the inline functions mentioned
24045 above can use them.
24047 * dired.c (directory_files_internal_unwind): Now static.
24049 * fileio.c (file_name_as_directory, directory_file_name):
24050 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
24052 (file_name_as_directory): Use const pointers when appropriate.
24053 (Fexpand_file_name): Likewise. In particular, newdir might
24054 point at constant storage, so make it a const pointer.
24055 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
24056 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
24058 (Fset_file_times, Finsert_file_contents, auto_save_error):

24063 to avoid shadowing.
24065 * marker.c (bytepos_to_charpos): Remove; unused.
24067 * lisp.h (verify_bytepos, count_markers): New decls,
24068 so that gcc does not warn that these functions aren't declared.
24070 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
24071 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
24072 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
24073 (copy_text): Remove unused local var.
24075 * filelock.c (within_one_second): Now static.
24076 (lock_file_1): Rename local to avoid shadowing.
24078 * buffer.c (fix_overlays_before): Mark locals as initialized.
24079 (fix_start_end_in_overlays): Likewise. This function should be
24080 simplified by using pointers-to-pointers, but that's a different
24082 (switch_to_buffer_1): Now static.
24083 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
24084 (report_overlay_modification): Rename locals to avoid shadowing.
24086 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
24087 Fix pointer signedness issue.
24088 (sys_subshell): Mark local as volatile if checking for lint,
24089 to suppress a gcc -Wclobbered warning that does not seem to be right.
24090 (MAXPATHLEN): Define only if needed.
24092 * process.c (serial_open, serial_configure): Move decls from here ...
24093 * systty.h: ... to here, so that they can be checked.
24095 * fns.c (get_random, seed_random): Move extern decls from here ...
24096 * lisp.h: ... to here, so that they can be checked.
24098 * sysdep.c (reset_io): Now static.
24099 (wait_for_termination_signal): Remove; unused.
24101 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
24102 (copy_keymap_item, append_key, push_text_char_description):
24104 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
24105 (DENSE_TABLE_SIZE): Remove; unused.
24106 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
24107 (describe_map_tree):
24108 Rename locals to avoid shadowing.
24110 * keyboard.c: Declare functions static if they are not used elsewhere.

24258 1152921504606846976) returns the obviously-bogus value (-948597
24259 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
24260 reports time overflow. See
