109 * w32.c (init_environment): Change the default values of many
110 environment variables in dflt_envvars[] to NULL, to avoid pushing
111 them into environment when they were not already defined. Remove
112 the code that deletes site-lisp subdirectories from the default
113 value of EMACSLOADPATH, as it is no longer needed.
114 (check_windows_init_file): Now external, not static. Use
115 Vload_path as is, without adding anything, as this function is now
116 called when Vload_path is already set up.
118 * w32.h (check_windows_init_file): Add prototype.
120 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

125 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
126 any, in the DEFALT argument into the root of the Emacs build or
127 installation tree, as appropriate.
129 * callproc.c (init_callproc_1): Call decode_env_path instead of
130 doing its equivalent by hand.
131 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
132 the code that sets Vexec_path run on MS-Windows.
134 * lread.c (init_lread): Add comments to #ifdef's.
136 * msdos.c (dos_set_window_size, IT_update_begin)
137 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

144 Now constants, not macros.
146 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
148 Remove unnecessary casts involving pointers.
149 These casts are no longer needed now that we assume C89 or later,

151 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
152 (make_pure_float, make_pure_vector):
153 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

163 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
164 Remove unnecessary pointer casts.
165 * alloc.c (record_xmalloc): New function.
166 * lisp.h (record_xmalloc): New decl.
167 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
168 more like a function. This is because the pointer cast is not
169 needed. All uses changed.
170 * print.c (print_string, print_error_message): Avoid length recalc.
172 Improve fix for macroexp crash with debugging (Bug#12118).
173 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
174 ARRAY_MARK_FLAG when checking subscripts, because ASET is
175 not supposed to be invoked from the garbage collector.
176 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
177 (gc_aset): New function, which is like ASET but can be
178 used in the garbage collector.

191 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
192 (map_w32_filename): Improve commentary. Simplify switch.
193 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
194 headers (most versions of MinGW w32api don't).
195 (get_security_info, create_symbolic_link)
196 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
198 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
199 in the argument file name.

201 GetFileAttributes fails with network-related error codes.
202 (sys_rename): Diagnose renaming of a symlink when the user doesn't
203 have the required privileges.
204 (get_file_security_desc_by_name): Renamed from
205 get_file_security_desc.
206 (stat_worker): New function, with most of the guts of 'stat', and
207 with addition of handling of symlinks and support for 'lstat'. If
208 possible, get file's attributes and security information by
209 handle, not by name. Produce S_IFLNK bit for symlinks, when
211 (stat, lstat): New functions, call 'stat_worker'.
212 (symlink, readlink, careadlinkat): Rewritten to create and resolve
213 symlinks when the underlying filesystem supports them.
215 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
217 Fix macroexp crash on Windows with debugging (Bug#12118).
218 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
219 checking subscripts; problem introduced with the recent
220 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
221 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
222 since it's used in non-static inline functions now.
224 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
225 Don't assume buffer size fits in 'int'. Remove unused local.
227 Use C99-style 'extern inline' if available.
228 * buffer.h (BUFFER_INLINE):
229 * category.h (CATEGORY_INLINE):
230 * character.h (CHARACTER_INLINE):

245 * composite.c (COMPOSITE_INLINE):
246 * dispnew.c (DISPEXTERN_INLINE):
247 * sysdep.c (SYSTIME_INLINE):
248 Define to EXTERN_INLINE, so that the corresponding functions
249 are compiled into code.
250 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
251 (INLINE_HEADER_END): New macros.
252 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

274 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
276 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
277 This how ASET and AREF are supposed to work, and makes
278 it easier to think about future improvements. See
279 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
280 * charset.h (set_charset_attr): New function.

534 does that unconditionally. Remove file, which is now empty.
536 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
539 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

661 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
662 (w32_kbd_patch_key, key_event): Use the codepage returned by

690 2012-07-27 Eli Zaretskii <eliz@gnu.org>
692 * alloc.c (listn): Fix the order the arguments are consed onto the
695 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
696 enumeration constants, as PURE and HEAP are too general, and clash
697 with other headers and sources, such as gmalloc.c and the
698 MS-Windows system headers. All users changed.
700 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

715 Improve GDB symbol export (Bug#12036).
716 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different

718 complains about the types in the unevaluated arm when the argument
719 is an integer literal.
720 (xgetint): Simplify expression.
721 * alloc.c (gdb_make_enums_visible): New constant. This ports to
722 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
723 Zaretskii in <http://bugs.gnu.org/12036#13>.
724 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
725 needed now that we have gdb_make_enums_visible.

770 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
771 emacs.c, as this is a more-suitable home. Had this been done earlier
772 the fix for 12036 would have avoided some of the problems noted in
773 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
774 would have been more obvious.
775 * emacs.c: Do not include <verify.h>; no longer needed.
776 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
777 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)

784 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
785 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
786 not be usable in #if. This simplifies things.
788 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
790 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
792 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

795 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
796 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
797 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
798 Adjust to changes in lisp.h and emacs.c, by using
799 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
800 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
801 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
802 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
803 instead of gdb_valbits.
804 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
805 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
806 instead of gdb_array_mark_flag.
807 (xboolvector): Get size from $->size, not $->header.size.
808 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
809 (xreload, hook-run, hookpost-run): Remove.
810 * emacs.c: Include <verify.h>.
811 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
812 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
814 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
815 (gdb_USE_LSB_TAG): New enum constants.
816 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

819 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
820 as constants, so they're visible to GDB.
821 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
822 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
823 Now enum constants, not macros, so they're visible to GDB.
824 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
825 more convenient now. All uses changed.
826 (VALMASK) [USE_LSB_TAG]: Also define in this case.

837 add argument, tune behavior, and adjust all callers.
839 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
841 Use typedef for EMACS_INT, EMACS_UINT.
842 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
843 than macros. This simplifies debugging in the usual case, since
844 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
845 and it allows expressions involving EMACS_INT casts.
846 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
848 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

860 Adjust buffer text indirection counters at the end of Fkill_buffer.
861 * buffer.c (Fkill_buffer): Adjust indirection counters when the
862 buffer is definitely dead. This should really fix an issue reported
863 by Christoph Scholtes again. (Bug#12007).
864 (init_buffer_once): Initialize indirection counters of
865 buffer_defaults and buffer_local_symbols (for sanity and safety).
867 2012-07-24 Eli Zaretskii <eliz@gnu.org>
869 * xdisp.c (init_iterator): Don't compute dimensions of truncation
870 and continuation glyphs on tooltip frames, leave them at zero.
871 Avoids continued lines in tooltips. (Bug#11832)
873 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
875 Simplify copy_overlay.
876 * buffer.c (copy_overlay): Simplify. Use build_marker.

882 or invalid. (Bug#12025)
884 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
885 it signals an error when a tooltip frame is being created.
887 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

900 Swap buffer text indirection counters in Fbuffer_swap_text.
901 * buffer.c (Fbuffer_swap_text): Swap indirections too.
902 This avoids crash reported by Christoph Scholtes at
903 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
905 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
907 * nsmenu.m (Popdown_data): New struct.
908 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
910 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
911 (initWithContentRect): Make imgView and contentView non-static
912 and autorelease them. Also autorelease img and matrix (Bug#12005).
913 (dealloc): Remove (Bug#12005).

1661 * s/aix4-2.h (unix): Remove; no longer needed.
1663 EMACS_TIME simplification (Bug#11875).
1664 This replaces macros (which typically do not work in GDB)

1666 The functional style also makes code easier to read and maintain.
1667 * systime.h: Include <sys/time.h> on all hosts, not just if
1668 WINDOWSNT, since 'struct timeval' is needed in general.

1706 * nsterm.m: Include <ftoastr.h>.
1708 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1709 Prefer snprintf to strncpy.
1710 * nsterm.m (ns_term_init):
1711 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1712 * nsterm.m (ns_term_init):
1713 Avoid the need for strncpy, by using build_string or
1714 make_unibyte_string directly. Use dtoastr, not snprintf.
1715 * process.c (Fmake_network_process): Diagnose service names that
1716 are too long, rather than silently truncating them or creating
1717 non-null-terminated names.

1734 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1735 where argument type is known to be a Lisp_Cons.

1787 We include usg5-4-common.h, which defines them both.
1789 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1790 O_RDONLY already includes it).
1792 Stop ns builds setting the EMACSLOADPATH environment variable.
1793 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1794 Now it does not set EMACSLOADPATH, just returns the load-path string.
1795 * nsterm.h: Update accordingly.
1796 * lread.c [HAVE_NS]: Include nsterm.h.
1797 (init_lread) [HAVE_NS]: Use ns_load_path.

1807 (ns_init_paths): Do not set EMACSPATH.
1808 * nsterm.h (ns_exec_path): Add it.

1833 Minor improvements to make_formatted_string.
1834 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1835 where int is good enough, as vsprintf returns an int.
1836 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1838 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1840 Use make_formatted_string to avoid double length calculation.
1841 * lisp.h (make_formatted_string): New prototype.
1842 * alloc.c (make_formatted_string): New function.

1846 * filelock.c (get_boot_time): Likewise.
1847 * frame.c (make_terminal_frame, set_term_frame_name)
1848 (x_report_frame_params): Likewise.
1849 * image.c (gs_load): Likewise.

1861 * nsterm.h (ns_etc_directory): Add it.
1862 * callproc.c [HAVE_NS]: Include nsterm.h.
1863 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1865 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1867 Move marker debugging code under MARKER_DEBUG.
1868 * marker.c (MARKER_DEBUG): Move marker debugging code under
1869 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1870 for bootstrap with --enable-checking (~3x slowdown reported
1871 by Juanma Barranquero <lekktu@gmail.com>).
1872 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1874 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1876 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1877 See <http://bugs.gnu.org/11825#29>.
1879 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1881 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1882 has no font, use the frame's font. (Bug#11813)
1883 (display_line): Add commentary about displaying truncation glyphs
1885 (produce_special_glyphs): Move here from term.c.
1887 * term.c (produce_special_glyphs): Move to xdisp.c.
1889 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1892 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1894 * xdisp.c (display_line): Avoid warning about implicit declaration
1897 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.

1901 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1903 * lread.c (load_path_check): Now static.
1905 Fix some minor --with-ns problems found by static checking.
1906 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1907 (x_set_font) [!HAVE_X_WINDOWS]:
1908 * image.c (xpm_load_image) [HAVE_NS]:
1909 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1910 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1911 Remove unused local.
1912 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1913 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1914 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1915 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1916 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1917 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1918 Fix pointer signedness problem.
1919 * xfaces.c (FRAME_X_FONT_TABLE):
1920 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1922 2012-07-07 Glenn Morris <rgm@gnu.org>
1924 * lread.c (load_path_check): New function, split from init_lread.
1925 (init_lread): Reorganize. Motivation:
1926 If EMACSLOADPATH is set, check/warn about that rather than the
1927 defaults, which we are not going to use. Hence we can remove
1928 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1929 Don't warn if site-lisp directories are missing.
1930 If not installed, start from a blank load-path, since
1931 PATH_LOADSEARCH refers to the eventual installation directories.
1933 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1935 Support truncation and continuation glyphs on GUI frames, when
1936 fringes are disabled. (Bug#11832)
1937 * xdisp.c (init_iterator): Get dimensions of truncation and
1938 continuation glyphs even if on GUI frames. Adjust
1939 it->last_visible_x on GUI frames when the left or right fringes,
1940 or both, are absent.
1941 (start_display, move_it_in_display_line_to): Handle the case of a
1942 GUI frame without a fringe to display continuation or truncation
1944 (insert_left_trunc_glyphs): Support GUI frames: make sure
1945 truncation glyphs overwrite enough glyphs from the current line to
1946 have sufficient space in pixels.
1947 (display_line): Support truncation and continuation glyphs on GUI
1948 frames. If some spare pixels are left on the line after inserting
1949 the truncation glyphs, fill that space with a stretch glyph of a
1950 suitably computed width.
1952 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1953 produce_glyphs, to support GUI sessions.
1955 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1957 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1959 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1961 Do not require float-time's arg to fit in time_t (Bug#11825).
1962 This works better on hosts where time_t is unsigned, and where
1963 float-time is applied to the (negative) difference between two times.
1964 * editfns.c (decode_time_components): Last arg is now double *,
1965 not int *, and means to store all the result as a double, without
1966 worrying about whether the seconds part fits in time_t.
1967 All callers changed.
1968 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1969 All callers changed.
1970 (Ffloat_time): Do not fail merely because the specified time falls
1971 outside of time_t range.
1973 2012-07-07 Glenn Morris <rgm@gnu.org>
1975 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1981 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1982 Update dependencies.
1984 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1986 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1988 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1989 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1990 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1991 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1992 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1993 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1995 * xfont.c (compare_font_names): Redo to omit the need for casts.
1997 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1999 * xfns.c (Fx_change_window_property): Doc fix.
2000 * w32fns.c (Fx_change_window_property): Doc fix.
2002 * w32fns.c (Fx_window_property): Accept the same arguments as the
2003 X Windows version. Doc fix.
2004 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2006 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2007 Eli Zaretskii <eliz@gnu.org>
2009 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2010 Windows-specific code from nt/config.nt moved here.
2011 Obsolete settings removed.
2013 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2015 * process.c: Avoid unnecessary calls to gettime.
2016 (wait_reading_process_output): Don't get the time of day
2017 when gobbling data immediately and not waiting, as there's no need
2018 for it in that case. This removes a FIXME.
2020 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2022 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2023 is defined (Bug#11768).
2025 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2027 Fix marker debugging code.
2028 * marker.c (byte_char_debug_check): Do not perform the check
2029 if buffer is not multibyte.
2030 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2031 Call byte_char_debug_check with correct arguments.
2033 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2035 Compile marker debugging code only if ENABLE_CHECKING is defined.
2036 * marker.c (byte_char_debug_check, count_markers):
2037 Use only if ENABLE_CHECKING is defined.
2038 (byte_debug_flag): Remove.
2039 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2040 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2042 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2044 Avoid code repetition in marker-related functions.
2045 * marker.c (attach_marker): New function.
2046 (Fset_marker, set_marker_restricted, set_marker_both)
2047 (set_marker_restricted_both): Use it.
2048 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2049 Consistently rename charno to charpos.

2066 * editfns.c (buildmark): Remove.
2067 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2068 (save_restriction_save): Use build_marker.
2069 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2070 * window.c (save_window_save): Likewise.
2072 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2074 Do not use Fdelete_overlay in delete_all_overlays
2075 to avoid redundant calls to unchain_overlay.
2076 * buffer.c (drop_overlay): New function.
2077 (delete_all_overlays, Fdelete_overlay): Use it.
2078 * minibuf.c (get_minibuffer): Fix comment.
2080 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2082 Port to OpenBSD 5.1 amd64.
2083 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2084 This is needed for OpenBSD, and should be harmless on all BSD systems.
2085 Also, include <sys/sysctl.h>, as it should be available on all
2086 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2087 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2088 use p_pid member, not kp_proc.pid.
2090 2012-07-06 Glenn Morris <rgm@gnu.org>
2092 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2094 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2096 More xmalloc and related cleanup.
2097 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2098 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2105 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2107 Omit needless casts involving void * pointers and allocation.
2108 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2109 as the former is more robust if P's type is changed.
2110 Prefer xzalloc to xmalloc + memset 0.
2111 Simplify malloc-or-realloc to realloc.
2112 Don't worry about xmalloc returning a null pointer.
2113 Prefer xstrdup to xmalloc + strcpy.
2114 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2116 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2117 alloca of a constant.
2119 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2121 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2122 hscroll is larger than the line width. Fixes long and futile
2123 looping inside extend_face_to_end_of_line (on a TTY) producing
2124 glyphs that are not needed and thrown away.
2126 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2128 * marker.c (set_marker_restricted_both): Simplify by using

2144 (update_theme_scrollbar_width, xg_create_scroll_bar):
2145 Use gtk_scrollbar_new (Bug#11768).

2154 * xdisp.c (window_hscroll_limited): New function.
2155 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2156 coordinates when window's hscroll is set to insanely large
2159 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2161 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2228 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2229 This should be fixed in a better way; see Eli Zaretskii in
2230 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2231 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2233 * fileio.c (time_error_value): Rename from special_mtime.
2234 The old name's problems were noted by Eli Zaretskii in
2235 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2237 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2238 This variable's comment says Emacs needs at least one GDB-visible
2239 symbol of type enum pvec_type, to work around GDB problems.
2240 The symbol's value doesn't matter.
2242 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2243 that causes compilation to fail on pre-C99 compilers.
2245 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

2273 abusing vector->header.next.nbytes.
2274 (live_vector_p): Use PVEC_TYPE.
2275 (mark_object): Adapt code to extract pvectype. Use switch.
2277 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2279 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2280 Tighten new eassert a bit.
2282 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2284 Fix compilation with --enable-gcc-warnings and -O1
2286 * doprnt.c (doprnt): Change type of tem to int, initialize
2287 to avoid compiler warning. Add eassert.
2288 * search.c (simple_search): Initialize match_byte to avoid
2289 compiler warning. Add eassert.
2291 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2293 Avoid weird behavior with large horizontal scrolls.
2294 Without this change, for example, large hscroll values would
2295 mess up Emacs's display on Fedora 15 x86, presumably due to
2296 overflows in int calculations in the display code.
2297 Also, if buffers had long lines, Emacs would freeze.
2298 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2299 (set_window_hscroll): New function, containing the old guts of
2300 Fset_window_hscroll. Return the clipped value.
2301 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2302 This avoids the need to check against PTRDIFF_MAX.
2304 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2306 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2308 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2310 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2312 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2313 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2314 since GCC 4.4.6 issues a bogus warning for them.
2316 Fix bugs in file timestamp newness comparisons.
2317 * fileio.c (Ffile_newer_than_file_p):
2318 * lread.c (Fload): Use full timestamp resolution of files,
2319 not just the 1-second resolution, so that files that are only
2320 slightly newer still count as newer.
2321 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2322 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2324 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2326 * fileio.c: Improve handling of file time marker. (Bug#11852)
2327 (special_mtime): New function.
2328 (Finsert_file_contents, Fverify_visited_file_modtime):
2329 Use it to set special mtime values consistently.
2331 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2333 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2334 marker for non-existing file. (Bug#11852)
2336 2012-07-03 Glenn Morris <rgm@gnu.org>
2338 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2339 and did not make it into globals.h).
2341 2012-07-03 Tom Tromey <tromey@redhat.com>
2343 * window.c (Fset_window_margins, Fset_window_fringes)
2344 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2345 * textprop.c (Fprevious_property_change): No longer static.
2346 * syntax.c (Fsyntax_table_p): No longer static.
2347 * process.c (Fget_process, Fprocess_datagram_address): No longer

2361 * dired.c (Ffile_attributes): No longer static.
2362 * composite.c (Fcomposition_get_gstring): No longer static.
2363 * callproc.c (Fgetenv_internal): No longer static.
2365 * ccl.h: Remove EXFUNs.

2368 * intervals.h: Remove EXFUNs.
2369 * fontset.h: Remove EXFUN.
2370 * font.h: Remove EXFUNs.
2371 * dosfns.c (system_process_attributes): Remove EXFUN.
2372 * keymap.h: Remove EXFUNs.
2373 * lisp.h: Remove EXFUNs.
2374 * w32term.h: Remove EXFUNs.
2375 * window.h: Remove EXFUNs.
2376 * xsettings.h: Remove EXFUN.
2377 * xterm.h: Remove EXFUN.
2379 2012-07-03 Glenn Morris <rgm@gnu.org>
2381 * lisp.h (Frandom): Make it visible to C.
2382 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2383 buffer for invisible buffers. (Bug#1229)
2385 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2387 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2388 values which aren't power of 2.
2389 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2390 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2393 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2395 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2397 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2399 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2401 * alloc.c (allocate_vector_block): Remove redundant
2402 calls to mallopt if DOUG_LEA_MALLOC is defined.
2403 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2404 avoid calls to mallopt if zero_vector is returned.
2406 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2408 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2409 is enabled, avoid dereferencing NULL current_sblock if
2412 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2414 Cleanup basic buffer management.
2415 * buffer.h (struct buffer): Change layout to use generic vector
2416 marking code. Fix some comments. Change type of 'clip_changed'
2417 to bitfield. Remove unused #ifndef old.
2418 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2419 (GET_OVERLAYS_AT): Fix indentation.
2420 (for_each_per_buffer_object_at): New macro.
2421 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2422 (Fbuffer_local_variables): Use it.
2423 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2424 * alloc.c (allocate_buffer): Adjust to match new layout of
2425 struct buffer. Fix comment.
2426 (mark_overlay): New function.
2427 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2428 Lisp area of struct buffer.
2429 (mark_object): Use it. Adjust marking of misc objects
2430 and related comments.
2432 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2434 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2435 wrapper that is not needed because the wrapped code is a no-op (zero
2436 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2437 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2439 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2441 * alloc.c (mark_buffer): Simplify. Remove prototype.
2442 (mark_object): Add comment. Reorganize marking of vector-like
2443 objects. Use CHECK_LIVE for all vector-like objects except buffers
2444 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2445 redundant calls to mark_vectorlike for bool vectors.
2447 2012-06-30 Glenn Morris <rgm@gnu.org>
2449 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2451 * epaths.in (PATH_SITELOADSEARCH): New.
2452 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2453 This is rather than relying on --enable-locallisppath elements
2454 having "site-lisp" in their names. (Bug#10208#25, 11658)
2456 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2458 * w32proc.c (sys_select): Accept and ignore one more argument.
2460 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2462 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2463 (pselect) [!MS_DOS]: Redirect to sys_select.
2465 * sysdep.c: Don't include dos.h and dosfns.h.
2467 * process.c (sys_select):
2468 * msdos.c (sys_select): Accept one more argument and ignore it.
2470 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2471 adapt data types and code to that.
2474 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2475 which clashes with the gnulib function of the same name.
2477 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2479 * font.c (font_style_to_value, font_style_symbolic)
2480 (font_prop_validate_style): Add type checks for values in
2483 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2485 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2488 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2490 * xdisp.c (try_window_id): Undo last change.
2492 * w32.c (getwd): Adjust commentary about startup_dir.
2493 (init_environment): Always call sys_access, even in non-MSVC
2494 builds. Don't chdir to the directory of the Emacs executable.
2495 This undoes code from 1997 which was justified by the need to
2496 "avoid conflicts when removing and renaming directories". But its
2497 downside was that every relative file name was being interpreted
2498 relative to the directory of the Emacs executable, which can never
2499 be TRT. In particular, it broke sys_access when called with
2500 relative file names.
2501 (sys_access): Map GetLastError to errno.
2503 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2505 * window.h (struct window): Change type of 'fringes_outside_margins'
2506 to bitfield. Fix comment. Adjust users accordingly.
2507 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2509 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2512 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2514 * gnutls.c (emacs_gnutls_handshake):
2515 Add QUIT to make the loop interruptible.
2517 2012-06-29 Glenn Morris <rgm@gnu.org>
2519 * charset.c (init_charset): Make lack of etc/charsets fatal.
2521 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2523 * editfns.c (region_limit): Fix type mismatch.
2525 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2527 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2528 undefined. Convert from xassert to eassert.
2529 * nsmenu.m: Convert from xassert to eassert.
2530 * nsterm.m: Likewise.
2532 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2534 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2536 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2538 Avoid integer overflow on scroll-left and scroll-right.
2539 * window.c (HSCROLL_MAX): New macro.
2540 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2541 overflow when requested scroll falls outside ptrdiff_t range.
2543 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2545 * window.h (struct window): Change type of 'hscroll',
2546 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2547 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2548 Adjust users accordingly.
2549 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2550 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2551 from EMACS_INT to ptrdiff_t.
2552 (make_window): Omit redundant initialization.
2554 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2558 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

2623 avoid GCC warning about unused macro.

2627 * alloc.c (allocate_string): Omit intervals initialization.
2628 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2629 as in make_pure_string and make_pure_c_string.
2631 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2633 * alloc.c (allocate_string): Fix last change.
2635 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2685 * alloc.c: Remove build_string.
2686 * lisp.h: Define build_string as static inline. This provides
2687 a better opportunity to optimize away calls to strlen when the
2688 function is called with compile-time constant argument.
2689 * image.c (imagemagick_error): Convert to build_string.
2690 * w32proc.c (sys_spawnve): Likewise.
2691 * xterm.c (x_term_init): Likewise.
2693 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2695 Use sprintf return value instead of invoking strlen on result.
2696 In the old days this wasn't portable, since some sprintf
2697 implementations returned char *. But they died out years ago and
2698 Emacs already assumes sprintf returns int.
2699 Similarly for float_to_string.
2700 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2701 * ccl.c (ccl_driver):

2707 * xfns.c (syms_of_xfns):
2708 Use sprintf or float_to_string result to avoid need to call strlen.
2709 * data.c (Fnumber_to_string):
2710 Use make_unibyte_string, since the string must be ASCII.
2711 * lisp.h, print.c (float_to_string): Now returns int length.
2712 * term.c (produce_glyphless_glyph):
2713 Use sprintf result rather than recomputing it.
2715 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2716 * Makefile.in (ALL_CFLAGS):

2748 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2753 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2754 instead of truncating it to 63 (admittedly a generous limit).

2884 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2886 Support higher-resolution time stamps (Bug#9000).
2887 The time stamps are only nanosecond-resolution at the C level,
2888 since that's the best that any real-world system supports now.
2889 But they are picosecond-resolution at the Lisp level, as that's
2890 easy, and leaves room for future OS improvements.
2892 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2895 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2896 Don't get current time unless it's needed.
2898 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2899 now provides it if it's absent.
2900 (start_atimer): Port to higher-res time stamps.
2901 Check for time stamp overflow. Don't get current time more
2902 often than is needed.
2904 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2905 Include systime.h, not time.h.
2906 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2908 * dired.c: Include stat-time.h.
2909 (Ffile-attributes): File times now have higher resolution.

2912 (struct image): Timestamp now has higher resolution.
2914 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2915 has at least microseconds now. All uses removed.
2916 (update_frame, update_single_window, update_window, update_frame_1)
2917 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2919 * editfns.c (time_overflow): Now extern.
2920 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2925 (decode_time_components, lisp_seconds_argument): New functions.
2926 (make_time): Now static.
2927 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2928 Report an error if the time is invalid, rather than having the caller
2931 * fileio.c: Include <stat-time.h>
2932 (Fcopy_file): Copy higher-resolution time stamps.
2933 Prefer to set the time stamp via a file descriptor if that works.

2935 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2936 (Fvisited_file_modtime, Fset_visited_file_modtime):
2937 Support higher-resolution time stamps.
2939 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2941 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2943 * image.c (prepare_image_for_display, clear_image_cache)
2944 (lookup_image): Port to higer-resolution time stamps.
2946 * keyboard.c (start_polling, bind_polling_period):
2947 Check for time stamp overflow.
2948 (read_char, kbd_buffer_get_event, timer_start_idle)
2949 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2950 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2951 Port to higher-resolution time stamps. Do not assume time_t is signed.
2952 (decode_timer): New function. Timers are now vectors of length 9,
2953 not 8, to accommodate the picosecond component.
2954 (timer_check_2): Use it.
2956 * nsterm.m (select_timeout, timeval_subtract): Remove.
2957 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2958 as they're a bit more accurate and handle overflow better.
2959 (ns_select): Change prototype to be compatible with pselect.
2960 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2961 * nsterm.h (ns_select): Adjust prototype.
2963 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2964 us-resolution time stamps.
2965 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2967 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2969 * lisp.h (time_overflow): New decl.
2970 (wait_reading_process_output): First arg is now intmax_t, not int,
2971 to accommodate larger waits.
2973 * process.h (struct Lisp_Process.read_output_delay):
2974 Now counts nanoseconds, not microseconds.
2975 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2977 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2978 (wait_reading_process_output):
2979 Port to ns-resolution time stamps.
2980 (Faccept_process_output, wait_reading_process_output):
2981 Check for time stamp overflow. Do not assume time_t is signed.
2982 (select_wrapper): Remove; we now use pselect.
2983 (Fprocess_attributes): Now generates ns-resolution time stamps.
2985 * sysdep.c: Include utimens.h. Don't include utime.h
2986 or worry about struct utimbuf; gnulib does that for us now.
2987 (gettimeofday): Remove; gnulib provides a substitute.
2988 (make_timeval): New function.
2989 (set_file_times): Now sets ns-resolution time stamps.
2990 New arg FD; all uses changed.
2991 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2992 (system_process_attributes):
2993 Now returns ns-resolution time stamp. All uses changed.
2994 Check for time stamp overflow.
2996 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2997 provides a substitute now.
2999 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3000 since it guarantees struct timespec.
3001 (EMACS_TIME): Now struct timespec, so that we can support
3002 ns-resolution time stamps.
3003 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3004 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3005 (EMACS_USECS): Remove.
3006 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3007 so multiply the arg by 1000 before storing it.
3008 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3010 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3011 Port to ns-resolution time stamps.
3012 (EMACS_TIME_NEG_P): Remove; replaced by....
3013 (EMACS_TIME_SIGN): New macro.
3014 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3015 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3016 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3017 (make_timeval, make_lisp_time, decode_time_components): New decls.
3018 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3019 that it mishandled time_t overflow. You can't compare by subtracting!
3020 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3021 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3023 * term.c: Include <sys/time.h>.
3024 (timeval_to_Time): New function, for proper overflow wraparound.

3032 (w32_get_internal_run_time):
3033 Port to higher-resolution Emacs time stamps.
3034 (ltime): Now accepts single 64-bit integer, as that's more convenient
3037 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3039 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3040 for compatibility with pselect. Support ns-resolution time stamps.
3042 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3044 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3045 Check for time stamp overflow, and support ns-resolution time stamps.
3047 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3048 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3049 (timeval_subtract): Remove; no longer needed.
3050 (XTflash, XTring_bell, x_wait_for_event):
3051 Port to ns-resolution time stamps. Don't assume time_t is signed.
3053 2012-06-22 Chong Yidong <cyd@gnu.org>

3057 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3059 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3060 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3061 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3062 staticidx goes up to 1597 out of 1600 = 0x640.)
3064 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3066 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3067 Otherwise, the umask might be mistakenly 0 while handling input signals.

3112 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3113 gets killed during executing of this function (Bug#11665).
3114 Try to always return Qt when the buffer has been actually killed.
3115 (Vkill_buffer_query_functions): In doc-string say that functions
3116 run by this hook should not change the current buffer.
3118 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

3141 This removes the need for CHECK.
3142 (CHECK): Remove. Its comments about always evaluating its
3143 argument were confusing, as 'eassert' typically does not evaluate
3146 * coding.c (produce_chars): Use ptrdiff_t, not int.
3148 * xterm.c (x_draw_underwave): Check for integer overflow.
3149 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3327 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
3328 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.

3331 USE_LSB_TAG now is always defined to be either 0 or 1.
3333 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3334 code works fine either way, and efficiency is not a concern here,
3335 as the union type is for debugging, not for production.
3336 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3337 Use an inline function on all platforms when using the union type,
3338 since this is simpler and 'static inline' can be used portably
3340 (LISP_INITIALLY_ZERO): New macro.
3341 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3342 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3480 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3482 * doprnt.c (doprnt): Truncate multibyte char correctly.
3483 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3484 would mishandle a string argument "Xc" if X was a multibyte
3485 character of length 2: it would truncate after X's first byte
3486 rather than including all of X.
3488 2012-06-06 Chong Yidong <cyd@gnu.org>
3490 * buffer.c (word_wrap): Doc fix.

3543 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3545 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3548 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3550 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3552 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3554 For a 'struct window', replace some Lisp_Object fields to
3555 bitfields where appropriate, remove unused fields.
3556 * window.h (struct window): Remove unused 'last_mark_x' and
3557 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3558 change it's type from Lisp_Object to bitfield.
3559 Change type of 'force_start', 'optional_new_start',
3560 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3561 fields from Lisp_Object to bitfield. Adjust users accordingly.

3569 and 'double' in a couple of places.
3571 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3573 * xdisp.c (handle_stop): Detect whether we have overlay strings
3574 loaded by testing it->current.overlay_string_index to be
3575 non-negative, instead of checking whether n_overlay_strings is
3576 positive. (Bug#11587)
3578 2012-05-31 Chong Yidong <cyd@gnu.org>
3580 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

3586 * search.c (search_buffer): Remove calls to
3587 r_alloc_inhibit_buffer_relocation, as it is now called by
3588 maybe_unify_char, which was the cause of relocation of buffer text
3591 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3593 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3594 for the duration of call to load_charset, to avoid problems with
3595 callers of maybe_unify_char that access buffer text through C
3598 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3599 decrement the inhibition flag, instead of just setting or
3602 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3604 Remove obsolete '#define static' cruft.
3605 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3606 This #undef was "temporary" in 2000; it is no longer needed

3608 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3609 (gray_bitmap_bits): Remove; no longer needed.
3610 All uses replaced with definiens.

3622 (safe_bcopy): Remove decl; no longer has that name.
3623 (main): Coalesce #if into single bit of code, for simplicity.

3654 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3655 Bug#9642, but explicitly check that the buffer the overlay would
3656 be moved to is live and rearrange lines to make sure that errors
3657 will not put the overlay in an inconsistent state.
3658 (Fdelete_overlay): Cosmetics.
3660 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3662 * w32term.c (my_bring_window_to_top): New function.
3663 (x_raise_frame): Use handle returned by DeferWindowPos, which

3698 the others were already declared.
3700 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3701 before checking whether it's out of range. Put the check inside
3703 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

3712 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3713 defined on ralloc.c.
3715 * buffer.c [REL_ALLOC]: Remove prototypes of

3717 they are now on lisp.h.
3719 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3721 * search.c (search_buffer): Use it to inhibit relocation of buffer
3722 text while re_search_2 is doing its job, because re_search_2 is
3723 passed C pointers to buffer text. (Bug#11519)
3725 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3728 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

3733 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3736 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3738 Fix coding-related core dumps with gcc -ftrapv.
3739 The code was computing A - B, where A and B are pointers, and B is
3740 random garbage. This can lead to core dumps on platforms that
3741 have special pointer registers, and it also leads to core dumps on
3742 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3743 A - B only when B is initialized properly.

3767 gen_help_event to produce help-echo message in the echo area.
3768 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3771 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3773 * lread.c (read1): Simplify slightly to avoid an overflow warning
3774 with GCC 4.7.0 on x86-64.
3776 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3778 * bidi.c (bidi_mirror_char): Revert last change: an int is
3779 definitely wide enough here.
3781 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

3795 Use int, not EMACS_INT, where int is wide enough.

3815 (Foverlay_recenter, last_overlay_modification_hooks_used)
3816 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3817 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3818 (validate_region): Omit unnecessary test for b <= e,
3819 since that's guaranteed by the previous test.
3820 (adjust_overlays_for_delete): Avoid pos + length overflow.
3821 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3822 (report_overlay_modification):

3824 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3833 not int, to avoid needless 32-bit limit on 64-bit hosts.
3834 (exec_byte_code): Use tighter memory-full test, one that checks
3835 for alloca overflow. Don't compute the address of the object just
3836 before an array, as that's not portable. Use EMACS_INT, not
3837 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3838 * callint.c (Fcall_interactively):
3839 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3851 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3852 (casify_object): Avoid integer overflow when overallocating buffer.
3853 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3855 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3856 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3857 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3860 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3861 For CCL_MapSingle, check that content and value are in int range.

3863 Check that Vcode_version_map_vector is a vector.
3864 (resolve_symbol_ccl_program): Check that vector header is in range.
3865 Always copy the vector, so that we can check its contents reliably
3866 now rather than having to recheck each instruction as it's being
3867 executed. Check that vector words fit in 'int'.
3868 (ccl_get_compiled_code, Fregister_ccl_program)
3869 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3870 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3872 contents are in range.
3873 (Fccl_execute_on_string): Check that status is in range.
3874 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3875 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3876 Accept and return EMACS_INT, not int, because callers can pass values

3883 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3885 avoid mishandling large integers.

3896 Don't rely on undefined behavior with signed left shift overflow.
3897 Don't assume unsigned int fits into fixnum, or that fixnum fits
3898 into unsigned int. Don't require max_code to be a valid fixnum;
3899 that's not true for gb10830 4-byte on a 32-bit host. Allow
3900 invalid_code to be a cons, for the same reason. Require code_offset
3901 to be a character. Avoid int overflow if max_char is close
3903 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3904 this is intended anyway and avoids some undefined behavior.
3905 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3906 INDEX_TO_CODE_POINT, as that's what it expects.
3907 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3908 * charset.h (DECODE_CHAR): Return int, not unsigned;
3909 this is what was intended anyway, and it avoids undefined behavior.
3910 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3911 integer-overflow issues.
3912 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3913 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3914 where the argument is EMACS_INT, and this behavior is not intended.
3915 * chartab.c (Fmake_char_table, Fset_char_table_range)
3916 (uniprop_get_decoder, uniprop_get_encoder):
3917 Don't assume fixnum fits in int.
3918 * cmds.c (move_point): New function, that does the gist of
3919 Fforward_char and Fbackward_char, but does so while checking
3920 for integer overflow more accurately.
3921 (Fforward_char, Fbackward_char): Use it.
3922 (Fforward_line, Fend_of_line, internal_self_insert)
3923 (internal_self_insert):
3924 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4624 what used to be in config.h, but not useful in #if.
4625 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4626 define them any more.
4627 (VAL_MAX): New macro.
4629 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4630 BITS_PER_EMACS_INT, in #if.

4632 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4633 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4634 * s/ms-w32.h (DATA_START):
4635 Move here from removed file m/intel386.h.
4636 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4637 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4639 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>

4705 2012-05-14 Glenn Morris <rgm@gnu.org>
4707 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4708 Put "libexec" before "bin", for the sake of init_callproc_1.
4710 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4712 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4714 * unexaix.c: Port to more-recent AIX compilers.
4715 (report_error, report_error_1, make_hdr, copy_sym)
4716 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4717 Make arguments const char *, not char *, to avoid violations of C
4718 standard and to fix some AIX warnings reported by Gilles Pion.
4720 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4722 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4723 already have overlays loaded.
4724 (handle_single_display_spec): Before returning without displaying
4725 fringe bitmap, synchronize the bidi iterator with the main display
4726 iterator, by calling iterate_out_of_display_property.
4727 (iterate_out_of_display_property): Detect buffer iteration by
4728 testing that it->string is a Lisp string.
4729 (get_next_display_element): When the current object is exhausted,
4730 and there's something on it->stack, call set_iterator_to_next to
4731 proceed with what's on the stack, instead of returning zero.
4732 (set_iterator_to_next): If called at the end of a Lisp string,
4733 proceed to consider_string_end without incrementing string
4734 position. Don't increment display vector index past the end of
4735 the display vector. (Bug#11417)
4736 (pos_visible_p): Don't report a position visible when move_it_to
4737 stopped at the last line of window, which happens to be scanned
4738 backwards by the bidi iteration. (Bug#11464)
4740 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4742 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4743 and right-margin display specs even if the spec is invalid or we
4744 are on a TTY, and thus unable to display on the fringes.
4745 That's because the text with the property will not be displayed anyway,
4746 so we need to signal to the caller that this is a "replacing"
4747 display spec. This fixes display when the spec is invalid or we
4750 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4752 * unexaix.c (make_hdr): Fix typo in prototype.
4753 This bug broke the build on AIX. Problem reported by Gilles Pion.
4755 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4757 * keyboard.c (kbd_buffer_get_event): Read special events also in
4758 batch mode. (Bug#11415)

4768 2012-05-12 Glenn Morris <rgm@gnu.org>

4771 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4773 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

4783 Update dependencies.
4785 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4787 * xgselect.c (xg_select): Put maxfds+1 into a var.
4788 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4790 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4792 2012-05-10 Dave Abrahams <dave@boostpro.com>
4794 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4795 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4797 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4799 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4800 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4801 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4802 Initialize xd_registered_buses.
4804 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4806 Untag more efficiently if USE_LSB_TAG.
4807 This is based on a proposal by YAMAMOTO Mitsuharu in
4808 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4809 For an admittedly artificial (nth 8000 longlist) benchmark on
4810 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4811 Emacs's overall text size by 1%.
4812 * lisp.h (XUNTAG): New macro.
4813 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4814 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4815 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4816 * eval.c (Fautoload):
4817 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4818 * frame.h (XFRAME): Use XUNTAG.
4820 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4821 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4822 Remove unportable assumptions about print widths of types like
4824 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4825 intptr_t when converting between pointer and integer, to avoid GCC
4826 warnings about wrong width.
4828 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4830 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4831 stack for each reader_thread, instead of defaulting to 8MB
4832 determined by the linker. This avoids failures in creating
4833 subprocesses on Windows 7, see the discussion in this thread:
4834 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4836 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4838 Fix up display of the *Minibuf-0* buffer in the mini window.
4839 * keyboard.c (read_char): Don't clear the echo area if there's no
4841 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4842 contents of *Minibuf-0*) if there's no message displayed in its stead.
4844 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4846 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4849 2012-05-06 Chong Yidong <cyd@gnu.org>
4851 * lisp.mk (lisp): Update.
4853 2012-05-05 Jim Meyering <meyering@redhat.com>
4855 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4857 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4859 * data.c (PUT_ERROR): New macro.
4860 (syms_of_data): Use it. Add new error type `user-error'.
4861 * undo.c (user_error): New function.
4862 (Fprimitive_undo): Use it.
4863 * print.c (print_error_message): Adjust print style for `user-error'.
4864 * keyboard.c (user_error): New function.
4865 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4867 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4869 Do not limit current-time-string to years 1000..9999.
4870 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4871 (Fcurrent_time_string): Support any year that is supported by the
4872 underlying localtime representation. Don't use asctime, as it
4873 has undefined behavior for years outside the range -999..9999.
4875 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4877 Fix race conditions involving setenv, gmtime, localtime, asctime.
4878 Without this fix, interrupts could mess up code that uses these
4879 nonreentrant functions, since setting TZ invalidates existing
4880 tm_zone or tzname values, and since most of these functions return
4881 pointers to static storage.
4882 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4883 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4884 Grow the critical sections to include not just invoking
4885 localtime/gmtime, but also accessing these functions' results
4886 including their tm_zone values if any, and any related TZ setting.
4887 (format_time_string): Last arg is now struct tm *, not struct tm **,
4888 so that the struct tm is saved in the critical section.
4889 All callers changed. Simplify allocation of initial buffer, partly
4890 motivated by the fact that memory allocation needs to be outside
4891 the critical section.
4893 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4895 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4896 with RESET_INTERVAL.
4898 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4899 Remove duplicated buffer name initialization.
4901 2012-05-02 Jim Meyering <jim@meyering.net>
4903 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4905 * xfns.c (x_window): Use xstrdup (Bug#11375).
4907 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4909 * xdisp.c (pos_visible_p): If already at a newline from the
4910 display string before the 'while' loop, don't walk back the glyphs
4911 from it3.glyph_row. Solves assertion violation when the display
4912 string begins with a newline (egg.el). (Bug#11367)
4914 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4916 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4919 2012-05-01 Glenn Morris <rgm@gnu.org>
4921 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4922 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4923 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4924 All were removed before 23.1.
4926 * dispnew.c: Remove HAVE_LIBNCURSES test;
4927 it is always true on relevant platforms.
4929 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4930 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4932 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4934 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4936 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4937 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4940 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4942 Do not avoid creating empty evaporating overlays (Bug#9642).
4943 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4944 That is, do not delete an evaporating overlay if it becomes
4945 empty after its bounds are adjusted to fit within its buffer.
4946 This fix caused other problems, and I'm reverting it until we get
4947 to the bottom of them.
4949 2012-04-27 Chong Yidong <cyd@gnu.org>
4951 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4953 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4955 * xdisp.c (pos_visible_p): If the window start position is beyond
4956 ZV, start the display from buffer beginning. Prevents assertion
4957 violation in init_iterator when the minibuffer window is scrolled
4960 * window.c (window_scroll_pixel_based): Likewise.
4962 2012-04-27 Chong Yidong <cyd@gnu.org>
4964 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4966 2012-04-27 Glenn Morris <rgm@gnu.org>
4968 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4969 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4971 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4973 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4974 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4976 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4978 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4979 display element, check also the underlying string or buffer
4980 character. (Bug#11341)
4982 * w32menu.c: Include w32heap.h.
4983 (add_menu_item): If the call to AppendMenuW (via
4984 unicode_append_menu) fails, disable Unicode menus only if we are
4985 running on Windows 9X/Me.
4987 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4989 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4990 (xgetint): Add missing shift for LSB tags.
4992 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4994 * keyboard.c (read_char): Don't wipe echo area for select window
4995 events: These might get delayed via `mouse-autoselect-window'
4998 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5000 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5001 manipulation of :loaded-from data.
5003 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5005 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5006 now a cons (bug#11311).
5008 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5010 Do not create empty overlays with the evaporate property (Bug#9642).
5011 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5012 if it becomes empty after its bounds are adjusted to fit within
5013 its buffer. Without this fix, in a nonempty buffer (let ((o
5014 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5015 yields an empty overlay that has the evaporate property, which is
5016 not supposed to happen.
5018 Fix minor GTK3 problems found by static checking.
5019 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5020 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5021 (struct _EmacsFixedClass, emacs_fixed_get_type):

5031 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5033 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5034 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5036 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5038 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5039 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5040 (__malloc_size_t, __malloc_ptrdiff_t):
5041 Remove. All uses removed, replaced by the definiens if needed,
5042 since we can assume C89 or better now.
5043 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

5053 Define using prototypes, not old style.
5054 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5055 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5056 (align): Don't assume that signed integer overflow wraps around.
5057 Omit unused local var.
5058 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

5118 * alloc.c: Handle unusual debugging option combinations.
5119 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5120 since the two debugging options are incompatible.
5121 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5123 (mem_init, mem_insert, mem_insert_fixup):
5124 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5133 * sysdep.c [__FreeBSD__]: Minor cleanups.
5134 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5135 Use Emacs indenting style more consistently. Avoid some casts.
5136 Use 'double' consistently rather than mixing 'float' and 'double'.
5138 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5140 * sysdep.c (list_system_processes, system_process_attributes):
5141 Add implementation for FreeBSD (Bug#5243).

5147 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
5149 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
5150 It is never used otherwise.
5152 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
5154 * print.c (print_preprocess): Only check print_depth if print-circle
5156 (print_object): Check for cycles even when print-circle is nil and
5157 print-gensym is t, but only check print_depth if print-circle is nil.
5159 2012-04-20 Chong Yidong <cyd@gnu.org>
5161 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5162 set the status to "failed" and ensure that sentinel is run.

5177 farther than the first row after the header line, if any.
5178 Don't consider the header-line row as "partially visible", even if
5179 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

5217 New extern decls, to avoid calling undeclared functions.
5218 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5219 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5220 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5221 (NEED_MEM_INSERT): New macro.
5222 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5223 Remove one incorrect comment and fix another.

5235 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5236 [REL_ALLOC]: ... to here, to check interface.
5237 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5238 Remove decls. This fixes an "It stinks!".
5240 * alloc.c (which_symbols): Fix alignment issue / type clash.
5242 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5244 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5245 (struct Lisp_Misc_Any): Likewise.

5255 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5257 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5258 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5259 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5260 * s/netbsd.h, s/sol2-6.h:
5261 Remove definition of GC_MARK_STACK, since the default now works.
5262 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5263 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5264 no longer the default.
5265 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5267 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5269 * lread.c (lisp_file_lexically_bound_p):

5290 2012-04-11 Daniel Colascione <dancol@dancol.org>
5292 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5293 against is gone. It's better to use vfork now so that when Cygwin
5294 gains a new, working vfork, we use it automatically (bug#10398).
5296 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5298 * window.c (save_window_save): Obey window-point-insertion-type.

5314 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5316 * w32.c (w32_delayed_load): Record the full path of the library
5317 being loaded (bug#10424).
5319 2012-04-09 Glenn Morris <rgm@gnu.org>
5321 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5322 not just in the obarray, before snarfing them. (Bug#11036)
5324 * Makefile.in ($(leimdir)/leim-list.el):
5325 Pass EMACS rather than BUILT_EMACS.
5327 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5329 * process.c (make_process):
5330 * process.h: Add integer `gnutls_handshakes_tried' member to
5333 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5334 Add convenience `GNUTLS_LOG2i' macro.
5336 * gnutls.c (gnutls_log_function2i): Convenience log function.
5337 (emacs_gnutls_read): Use new log functions,
5338 `gnutls_handshakes_tried' process member, and
5339 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5340 attempts per process (connection).
5342 2012-04-09 Chong Yidong <cyd@gnu.org>
5344 * eval.c (Fuser_variable_p, user_variable_p_eh)

5349 * minibuf.c (Fread_variable): Callers changed.
5351 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5353 * xdisp.c (set_cursor_from_row): If the display string appears in
5354 the buffer at position that is closer to point than the position
5355 after the display string, display the cursor on the first glyph of
5356 the display string. Fixes cursor display when a 'display' text
5357 property immediately follows invisible text. (Bug#11094)
5359 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5361 composite.c: use 'double' consistently
5362 * composite.c (get_composition_id): Use 'double' consistently
5363 instead of converting 'float' to 'double' and vice versa; this is
5364 easier to understand and avoids a GCC warning.
5366 2012-04-09 Glenn Morris <rgm@gnu.org>
5368 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5369 preparation for dumping it with emacs. (Bug#4789)
5370 (leimdir): New variable.
5371 ($(leimdir)/leim-list.el): New rule.

5388 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5390 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5391 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5392 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5393 objects, as mark_maybe_pointer will catch them otherwise.
5394 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5395 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5397 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5399 Fix typo that broke non-Windows builds.
5400 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5404 Support building on MS-Windows with libxml2.
5406 * makefile.w32-in (OBJ2): Add xml.$(O).
5407 (GLOBAL_SOURCES): Add xml.c.
5408 ($(BLD)/xml.$(O)): New dependency list.
5410 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5411 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5412 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5413 [!WINDOWSNT]: New macros.
5414 (init_libxml2_functions, libxml2_loaded_p): New functions.
5415 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5416 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5417 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5418 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5420 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5421 Call init_libxml2_functions before calling libxml2 functions.
5422 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5424 * emacs.c: Don't include libxml/parser.h.
5425 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5426 xmlCleanupParser directly.
5428 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5430 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5432 * indent.c (Fvertical_motion): If there is a display string at
5433 point, use it.vpos to compute how many lines to backtrack after
5434 move_it_to point. (Bug#11133)
5436 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5438 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5439 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5440 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5441 macros related to unification of CJK characters. For the details,
5442 see the discussion following the message here:
5443 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5445 2012-04-04 Chong Yidong <cyd@gnu.org>
5447 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5449 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5451 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5452 instead of alloca. (Bug#11138)
5454 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5456 * w32menu.c (is_simple_dialog): Properly check lisp types.
5459 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5461 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5462 position we get to after a call to move_it_to fails the
5463 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5464 only if we wind up in a string from display property. (Bug#11063)
5466 * window.c (Fdelete_other_windows_internal): Invalidate the row
5467 and column information about mouse highlight, so that redisplay
5468 restores it after reallocating the glyph matrices. (Bug#7464)
5470 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5471 string comes from a `display' text property, use the buffer
5472 position of that property as if we actually saw that position in
5474 (move_it_by_lines): Remove the assertion that
5475 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5476 violated when there's a before-string at the beginning of a line.
5479 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5481 * xdisp.c (append_space_for_newline): If the default face was
5482 remapped, use the remapped face for the appended newline.
5483 (extend_face_to_end_of_line): Use the remapped default face for
5484 extending the face to the end of the line.
5485 (display_line): Call extend_face_to_end_of_line when the default
5486 face was remapped. (Bug#11068)
5488 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5490 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5492 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5494 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5496 2012-03-27 Glenn Morris <rgm@gnu.org>
5498 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5501 2012-03-26 Kenichi Handa <handa@m17n.org>
5503 * dispextern.h (struct glyph): Fix previous change. Change the
5504 bit length of glyphless.ch to 25 (Bug#11082).
5506 2012-03-26 Chong Yidong <cyd@gnu.org>
5508 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5509 (command_loop_1): Use it; inhibit selection update for
5510 handle-select-window too (Bug#8996).
5512 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5514 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5516 2012-03-25 Kenichi Handa <handa@m17n.org>
5518 * dispextern.h (struct glyph): Change the bit length of
5519 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5521 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5523 * s/ms-w32.h (tzname): Include time.h before redirecting to
5524 _tzname. Fixes the MSVC build. (Bug#9960)
5526 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5528 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5531 * xterm.c (XTread_socket): Only modify handling_signal if
5532 !SYNC_INPUT. (Bug#11080)
5534 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5536 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5537 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5538 when fetching a multibyte character consumes more bytes than
5539 CHAR_BYTES returns, due to unification of CJK characters in
5540 string_char. (Bug#11073)
5542 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5544 * process.c (wait_reading_process_output): Handle pty disconnect
5545 by refraining from sending oneself a SIGCHLD (bug#10933).
5547 2012-03-22 Chong Yidong <cyd@gnu.org>
5549 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5551 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5552 Mark string as coming from a prefix property.
5553 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5554 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5556 2012-03-21 Chong Yidong <cyd@gnu.org>
5558 * xfaces.c (Vface_remapping_alist): Doc fix.
5560 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5562 * w32proc.c (Fw32_set_console_codepage)
5563 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5566 2012-03-20 Chong Yidong <cyd@gnu.org>
5568 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5569 to reflect default non-nil value of redisplay-dont-pause.
5571 2012-03-19 Kenichi Handa <handa@m17n.org>
5573 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5574 it fit in a valid range (Bug#11003).
5576 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5578 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5579 that is not from display property, accept the row as a "cursor
5580 row" if one of the string's character has a non-nil `cursor'
5581 property. Fixes cursor positioning when there are newlines in
5582 overlay strings, e.g. in icomplete.el. (Bug#11035)
5584 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5586 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5588 2012-03-12 Chong Yidong <cyd@gnu.org>
5590 * eval.c (inhibit_lisp_code): Rename from
5591 inhibit_window_configuration_change_hook; move from window.c.
5593 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5594 * window.c (run_window_configuration_change_hook)
5595 (syms_of_window): Callers changed.
5597 2012-03-11 Chong Yidong <cyd@gnu.org>

5606 is visible (Bug#10955).
5608 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5610 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5612 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5614 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5615 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5618 2012-03-03 Glenn Morris <rgm@gnu.org>
5620 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5622 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5624 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5625 position past the first glyph_row that ends at ZV. (Bug#10902)
5626 (redisplay_window, next_element_from_string): Fix typos in
5628 (redisplay_window): Pass to move_it_vertically the margin in
5629 pixels, not in screen lines.
5631 2012-03-02 Glenn Morris <rgm@gnu.org>
5633 * buffer.c (buffer-list-update-hook): Doc fix.
5635 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5637 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5638 push_it before setting up the iterator for the first overlay
5639 string, even if we have an empty string loaded.
5640 (next_overlay_string): If there's an empty string on the iterator
5641 stack, pop the stack. (Bug#10903)
5643 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5645 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5646 Suggested by Stefan Monnier in
5647 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5648 * alloc.c (widen_to_Lisp_Object): New static function.
5649 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5650 and widening them to Lisp_Objects. This would work even if
5651 USE_LSB_TAG is defined and wide integers are used, which might
5652 happen in a future version of Emacs.
5654 2012-02-25 Chong Yidong <cyd@gnu.org>
5656 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5659 * xselect.c (Fx_selection_exists_p): Doc fix.
5660 (x_clipboard_manager_save_all): Print an informative message
5661 before saving to clipboard manager.
5663 2012-02-24 Chong Yidong <cyd@gnu.org>
5665 * keyboard.c (process_special_events): Handle all X selection
5666 requests in kbd_buffer, not just the next one (Bug#8869).
5668 2012-02-23 Chong Yidong <cyd@gnu.org>
5670 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5671 call when setting menu-bar-lines and tool-bar-lines parameters.
5672 (unwind_create_frame_1): New helper function.
5674 * window.c (inhibit_window_configuration_change_hook): New var.
5675 (run_window_configuration_change_hook): Obey it.
5676 (syms_of_window): Initialize it.
5678 2012-02-22 Chong Yidong <cyd@gnu.org>

5693 when computing $valmask.
5695 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5696 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5697 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5698 It's useless in that case, and it can cause problems on hosts
5699 that allocate halves of EMACS_INT values separately.
5700 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5701 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5702 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5703 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5704 it avoids undefined behavior on hosts where shifting right by more
5705 than the word width has undefined behavior.
5707 2012-02-19 Chong Yidong <cyd@gnu.org>
5709 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5710 (Funhandled_file_name_directory, Ffile_name_as_directory)

5713 return values (Bug#10845).
5715 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5717 * .gdbinit (pitx): Fix incorrect references to fields of the
5720 2012-02-17 Chong Yidong <cyd@gnu.org>

5727 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5729 2012-02-15 Chong Yidong <cyd@gnu.org>
5731 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5732 marked as special. Also, starting docstrings with * is obsolete.

5747 2012-02-12 Chong Yidong <cyd@gnu.org>
5749 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5750 as that creates a dangerous corner case.
5752 * window.c (Fdelete_window_internal): Invalidate the mouse
5753 highlight (Bug#9904).
5755 2012-02-12 Glenn Morris <rgm@gnu.org>

5758 (Fx_get_selection_internal, Fx_disown_selection_internal)
5759 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5760 * nsselect.m (Fx_own_selection_internal)
5761 (Fx_disown_selection_internal, Fx_selection_exists_p)
5762 (Fx_selection_owner_p, Fx_get_selection_internal):
5763 Sync docs and argument specs with the xselect.c versions.
5765 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

5785 2012-02-07 Chong Yidong <cyd@gnu.org>
5787 * buffer.c (Fbuffer_local_variables)
5788 (buffer_lisp_local_variables): Handle unbound vars correctly;
5789 don't let Qunbound leak into Lisp.
5791 2012-02-07 Glenn Morris <rgm@gnu.org>
5793 * image.c (Fimagemagick_types): Doc fix.
5795 * image.c (imagemagick-render-type): Change it from a lisp object
5796 to an integer. Move the doc here from the lisp manual.

6322 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
6323 verifies glyph row's hash code--we have just reallocated the

6332 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Ensure ROW's
6333 attributes are tested _before_ calling verify_row_hash, to protect
6334 against GCC re-ordering of the tests. (Bug#10164)
6336 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>
6338 * xterm.h (struct x_output): net_wm_state_hidden_seen is new.

6357 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
6358 of scroll runs so as to avoid assigning disabled bogus rows and
6359 unnecessary graphics copy operations.
6361 2011-11-27 Eli Zaretskii <eliz@gnu.org>
6363 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.
6364 (snprintf) [_MSC_VER]: Redirect to _snprintf.

6370 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6371 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
6372 this macro definition.
6374 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
6377 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

6399 * xdisp.c (redisplay_window): If cursor row is not fully visible
6400 after recentering, and scroll-conservatively is set to a large
6401 number, scroll window by a few more lines to make the cursor fully
6402 visible and out of scroll-margin. (Bug#10105)
6403 (start_display): Don't move to the next line if the display should
6404 start at a newline that is part of a display vector or an overlay

6485 Otherwise, valgrind does not work on some platforms.
6486 Problem reported by Andreas Schwab in
6487 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6488 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6489 is set, removing the need for VIRT_ADDRESS_VARIES.
6490 (PURE_P): Use a more-efficient implementation that needs just one
6491 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6492 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6493 to 4 (xorl, subq, cmpq, setbe).
6494 * alloc.c (pure): Always extern now, since that's the
6495 VIRT_ADDR_VARIES behavior.
6496 (PURE_POINTER_P): Use a single comparison, not two, for
6497 consistency with the new puresize.h.
6498 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6499 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6505 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6506 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6507 behave as if the cursor position were at the window margin.
6509 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6510 and the cursor position is out of bounds, behave as if the cursor
6511 position were at the window margin. (Bug#10075)
6513 2011-11-18 Chong Yidong <cyd@gnu.org>
6515 * window.c (Fwindow_combination_limit): Make first argument
6516 non-optional, since it is meaningless for live windows like the

6531 hash values of the two rows.
6532 (copy_row_except_pointers): Preserve the used[] arrays and the
6533 hash values of the two rows. (Bug#10035)
6534 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
6536 * xdisp.c (row_hash): New function, body extracted from
6537 compute_line_metrics.
6538 (compute_line_metrics): Call row_hash, instead of computing the
6541 * dispnew.c (verify_row_hash): Call row_hash for computing the
6542 hash code of a row, instead of duplicating code from xdisp.c.
6544 * dispextern.h (row_hash): Add prototype.
6546 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6548 * frame.c (delete_frame): Don't delete the terminal when the last
6549 X frame is closed if emacs is built with GTK toolkit.

6571 (Fset_window_nest): Rename to Fset_window_combination_limit.
6572 (Vwindow_nest): Rename to Vwindow_combination_limit.
6573 (recombine_windows, make_parent_window, make_window)
6574 (Fsplit_window_internal, saved_window)
6575 (Fset_window_configuration, save_window_save): Rename all
6576 occurrences of window_nest to window_combination_limit.
6578 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6580 * image.c (imagemagick_load_image): Fix typo.
6582 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6584 * xdisp.c (display_line): Move the call to
6585 highlight_trailing_whitespace before the call to
6586 compute_line_metrics, since the latter needs to see the final
6587 faces of all the glyphs to compute ROW's hash value.
6588 Fixes assertion violations in row_equal_p. (Bug#10035)
6590 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6592 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6597 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6598 with user-defined heap size. Bump the default size of the temacs
6599 heap to 27MB, to avoid memory warning when running temacs.
6600 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6602 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6649 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6651 Avoid some portability problems by eschewing 'extern inline' functions.
6652 The trivial performance wins aren't worth the portability hassles; see
6653 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6655 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6656 (window_box_width, window_box_left, window_box_left_offset)
6657 (window_box_right, window_box_right_offset): Undo previous change,
6658 by removing the "extern"s.
6659 * intervals.c (adjust_intervals_for_insertion)
6660 (adjust_intervals_for_deletion): Undo previous change,
6661 making these static again.
6662 (offset_intervals, temp_set_point_both, temp_set_point)
6663 (copy_intervals_to_string): No longer inline.
6664 * xdisp.c (window_text_bottom_y, window_box_width)

6688 2011-11-07 Martin Rudalics <rudalics@gmx.at>
6690 * window.h: Declare delete_all_child_windows instead of

6703 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6704 This is also needed for porting to any host where GC_MARK_STACK is
6705 not GC_MAKE_GCPROS_NOOPS.
6706 (which_symbols): Use it.
6708 2011-11-07 Kenichi Handa <handa@m17n.org>

6721 * xmenu.c (cleanup_widget_value_tree): New function.
6722 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6729 (window_box_width, window_box_left, window_box_left_offset)
6730 (window_box_right, window_box_right_offset): Declare extern.
6731 Otherwise, these inline functions do not conform to C99 and
6732 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6733 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6734 * intervals.c (adjust_intervals_for_insertion)
6735 (adjust_intervals_for_deletion): Now extern, because otherwise the
6736 extern inline functions 'offset_intervals' couldn't refer to it.
6737 (static_offset_intervals): Remove.
6738 (offset_intervals): Rewrite using the old contents of
6739 static_offset_intervals. The old version didn't conform to C99
6740 because an extern inline function contained a reference to an
6741 identifier with static linkage.
6743 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6745 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6762 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6763 (Fwindow_vscroll): Doc fix.
6764 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6765 argument, since it makes no sense to pass a live window and for
6766 consistency with window-child.

6847 * xdisp.c (note_mouse_highlight): If either of
6848 previous/next-single-property-change returns nil, treat that as
6849 the beginning or the end of the buffer. (Bug#9955)
6851 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6853 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

6873 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6874 Don't stop backward scan on the continuation glyph, even though
6875 its CHARPOS is positive.
6876 (mouse_face_from_buffer_pos, note_mouse_highlight):
6877 Rename cover_string to disp_string.
6879 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6881 * window.c (temp_output_buffer_show): Don't use
6882 Vtemp_buffer_show_specifiers.

6916 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6918 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6920 2011-10-29 Eli Zaretskii <eliz@gnu.org>

6938 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6939 Not clear what it was for, and it causes various bugs. (Bug#9839)
6941 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6943 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6944 possible random value that matches one of those tested as
6945 condition to clear the mouse face.
6947 2011-10-28 Chong Yidong <cyd@gnu.org>
6949 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6951 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>

6963 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6965 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6966 <oslsachem@gmail.com> for helping to debug this.
6968 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6969 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6970 (g_b_init_get_glyph_outline_w): New static variables.
6971 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6972 (GetGlyphOutlineW_Proc): New typedefs.
6973 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6974 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6976 (w32font_open_internal, compute_metrics):
6977 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6978 instead of calling the "wide" APIs directly.
6980 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6982 * w32.h (syms_of_w32font): Add prototype.
6984 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6986 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6987 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6988 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

6993 * process.c (make_process): Set gnutls_state to NULL.
6995 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6996 non-NULL, regardless of GNUTLS_INITSTAGE.
6997 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6998 an error. Set process slots as soon as we allocate them.

7016 * w32reg.c (x_get_string_resource): Silence compiler warnings.
7018 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
7020 * w32fns.c (w32_default_color_map): New function,
7021 extracted from Fw32_default_color_map.
7022 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
7024 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
7026 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
7028 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
7030 * keyboard.c (test_undefined): New function (bug#9751).
7031 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7033 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7035 * sysdep.c (init_sys_modes): Fix the check for the controlling
7036 terminal (Bug#6649).
7038 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7040 * dispextern.h (struct bidi_it): New member next_en_type.
7042 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7043 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7044 current character, check also for next_en_type being WEAK_EN.
7045 (bidi_resolve_weak): Don't enter the expensive loop if the current
7046 position is before next_en_pos. Record the bidi type of the first
7047 non-ET, non-BN character we find, in addition to its position.
7048 (bidi_level_of_next_char): Invalidate next_en_type when
7049 next_en_pos is over-stepped.
7051 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7053 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7054 * editfns.c: Rewrite current-time-zone so that it invokes
7055 the equivalent of (format-time-string "%Z") to get the time zone name.
7056 This fixes a bug when the time zone name contains characters that
7057 need converting from the system time locale to Emacs internal format.
7058 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7059 that patch fixed format-time-string to do the conversion, but
7060 I forgot to fix current-time-zone.
7061 (format_time_string): New function, containing most of
7062 what Fformat_time_string used to contain.
7063 (Fformat_time_string): Rewrite in terms of format_time_string.
7064 This doesn't change this function's behavior.
7065 (current-time-zone): Rewrite to use format_time_string.
7066 This fixes the bug reported by Michael Schierl in
7067 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7068 Jason Rumney's 2007-06-07 change worked around this bug, but
7070 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7072 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7074 * xdisp.c (start_display): If the character at POS is displayed
7075 via a display vector, reset IT->current.dpvec_index to zero.
7076 (try_window_reusing_current_matrix): If a line ends in a display
7077 vector or the next line starts in a display vector, continue
7078 redrawing the window even though the character position of
7079 start_row was reached.
7082 2011-10-18 Chong Yidong <cyd@gnu.org>
7084 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7085 with nobreak-char-display too.
7087 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7089 Fix part 3 of bug#9771.
7090 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7091 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7092 non-neutral characters if the current character is a paragraph
7093 separator (a.k.a. Newline). This avoids running the same
7094 expensive loop twice, once when we consume the preceding newline
7095 and the other time when the line actually needs to be displayed.
7096 Avoid the loop when we see neutrals on the base embedding level
7097 following a character whose directionality is the same as the
7098 paragraph's. This avoids running the expensive loop when a line
7099 ends in a long sequence of neutrals, like control characters.
7100 Add assertion against STRONG_AL type. Slightly rearrange code
7101 that determines the type of a neutral given the first non-neutral
7103 (bidi_level_of_next_char): Set next_en_pos to zero when
7104 invalidating its info.
7106 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7108 * xdisp.c (push_display_prop): Determine whether to record string
7109 or buffer position by IT->string, not by IT->method. Allow
7110 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7111 (move_it_vertically_backward): Don't look for character position
7112 immediately after the newline when in a continuation line.
7115 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7117 * window.c (coordinates_in_window): Rewrite and delabelize
7118 vertical border check. (Bug#5357) (Bug#9618)
7120 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7122 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7123 errors in XSetWindowBorder (bug#9310).
7125 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7127 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7128 avoid crash when xmalloc overrun checking is enabled.
7130 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7132 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7133 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7134 cursor motion with <left> and <right> arrow keys.
7136 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7137 some callers set that themselves.
7139 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7141 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7142 display string and the previous row comes from the same string and
7143 is empty. (Bug#9739) (Bug#9738)
7145 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7147 * doc.c (get_doc_string): Encode file name (bug#9735).
7149 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7151 * bidi.c (bidi_level_of_next_char):
7152 * xdisp.c (get_visually_first_element): Remove old incorrect
7153 comments regarding the Unicode Line Separator character.
7155 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7157 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7159 * alloc.c (Fgc_status): Do not access beyond zombies array
7160 boundary if nzombies > MAX_ZOMBIES.
7161 * alloc.c (dump_zombies): Add missing format specifier.
7163 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7165 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7166 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7168 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7169 Some packages use them to denote characters with modifiers.
7171 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7173 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7174 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7175 matching a pp-number. Rename parameter var to var1.
7177 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7179 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7181 2011-10-08 Glenn Morris <rgm@gnu.org>
7183 * callint.c (Fcall_interactively): Give a more explicit error for the
7184 'c' case with a non-character input. (Bug#8479)
7186 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7188 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7190 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7191 lines that are hscrolled on the left.
7193 * dispnew.c (buffer_posn_from_coords): Account for a possible
7194 presence of header-line. (Bug#4426)
7196 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7198 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7199 Don't advertise functionality which we discourage or doesn't work.
7201 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7203 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7204 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7205 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7206 this makes Emacs dump core during garbage collection on rare
7207 occasions. sizeof is obviously inferior to offsetof here, so
7208 stick with offsetof.
7209 (GC_POINTER_ALIGNMENT): New macro.
7210 (mark_memory): Omit 3rd (offset) arg; caller changed.
7211 Don't assume EMACS_INT alignment is the same as pointer alignment.
7213 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7215 * keyboard.c (read_key_sequence_remapped): New var.
7216 (read_key_sequence): Compute remapping in the right buffer.
7217 (command_loop_1): Use read_key_sequence's remapping directly.
7219 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7221 * dired.c (file_name_completion): Don't expand file name.
7222 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7223 before checking file name handler.
7225 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7226 they've been requested explicitly (bug#9591).
7228 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7230 * keymap.c (Fsingle_key_description): Use make_specified_string
7231 instead of build_string to build string from push_key_description.
7234 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7236 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7237 This fixes a Y2038 bug on 64-bit hosts.
7238 * buffer.c (reset_buffer):
7239 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7240 (Fclear_buffer_auto_save_failure):
7241 Use 0, not -1, to represent an unset failure time, since time_t
7242 might not be signed.
7244 Remove dependency on glibc malloc internals.
7245 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7246 Move back here from lisp.h, but with their new implementations.
7247 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7248 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7249 * charset.c (charset_table_init): New static var.
7250 (syms_of_charset): Use it instead of xmalloc. This removes a
7251 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7252 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7253 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7254 Move back to alloc.c.
7255 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7256 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7258 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7260 * nsterm.m (windowDidResize): Call x_set_window_size only when
7261 ns_in_resize is true. Otherwise set pixelwidth/height and
7262 call change_frame_size (Bug#9628).
7264 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7266 Port --enable-checking=all to Fedora 14 x86-64.
7267 * charset.c (syms_of_charset): Also account for glibc malloc's
7268 internal overhead when calculating the initial malloc maximum.
7270 Port --enable-checking=all to Fedora 14 x86.
7271 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7273 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7274 (overrun_check_realloc, overrun_check_free):
7275 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7276 That way, xmalloc returns a properly-aligned pointer even if
7277 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7278 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7279 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7280 into account when calculating the initial malloc maximum.
7281 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7282 Move here from alloc.c, so that charset.c can use it too.
7283 Properly align; the old code wasn't right for common 32-bit hosts
7284 when configured with --enable-checking=all.
7285 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7286 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7288 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7290 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7293 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7295 * xdisp.c (compute_display_string_end): If there's no display
7296 string at CHARPOS, return -1.
7298 * bidi.c (bidi_fetch_char): When compute_display_string_end
7299 returns a negative value, treat the character as a normal
7300 character not covered by a display string. (Bug#9624)
7302 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7304 * lread.c (Fread_from_string): Fix typo in docstring.
7306 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7308 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7309 newline, reseat the iterator instead of bidi-iterating there one
7310 character at a time. (Bug#9610)
7311 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7312 TO_CHARPOS if the bidi iterator is at base embedding level.
7314 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7316 * lread.c (readevalloop): Use correct code for NBSP.
7317 (read1): Likewise. (Bug#9608)
7319 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7321 * dbusbind.c (Fdbus_register_signal): When service is not
7322 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7324 2011-09-25 Glenn Morris <rgm@gnu.org>
7326 * buffer.c (truncate-lines): Doc fix.
7328 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7330 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7331 (Fset_window_next_buffers): Doc fix.
7333 2011-09-24 Glenn Morris <rgm@gnu.org>
7335 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7337 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7339 Fix minor problems found by static checking.
7340 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7341 * indent.c (Fvertical_motion): Fix == vs = typo.
7343 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7345 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7346 Default value is now t. Doc fix.
7348 * indent.c (Fvertical_motion): Compute and apply the overshoot
7349 logic when moving up, not only when moving down. Fix the
7350 confusing name and values of the it_overshoot_expected variable;
7351 logic changes accordingly. (Bug#9254) (Bug#9549)
7353 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7354 CHARPOS is covered by a display string which includes newlines.
7355 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7356 is covered by a display string with embedded newlines.
7358 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7360 * dbusbind.c (Fdbus_register_signal): Add match rule to
7361 Vdbus_registered_objects_table. (Bug#9581)
7362 (Fdbus_register_method, Vdbus_registered_objects_table):
7365 2011-09-24 Jim Meyering <meyering@redhat.com>
7367 do not ignore write error for any output size
7368 The previous change was incomplete.
7369 While it makes emacs --batch detect the vast majority of stdout
7370 write failures, errors were still ignored whenever the output size is
7371 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7372 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7373 && echo FAIL: ignored write error
7374 FAIL: ignored write error
7375 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7376 && echo FAIL: ignored write error
7377 FAIL: ignored write error
7378 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7380 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7382 * emacs.c (Fkill_emacs): In noninteractive mode exit
7383 non-successfully if a write error occurred on stdout. (Bug#9574)
7385 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7387 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7390 * dispextern.h (struct it): Update the comment documenting what
7393 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7395 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7396 a display string, extend search for cursor position to end of row.
7397 (find_row_edges): If the row ends in a newline from a display
7398 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7399 Handle the case of a display string with multiple newlines.
7400 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7401 non-empty line. Fixes confusing cursor motion with arrow keys at
7402 the beginning of a line that starts with whitespace.
7404 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7406 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7409 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7411 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7414 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7416 * xdisp.c (display_line): Record maximum and minimum buffer
7417 positions even if no glyphs were produced (e.g., by a zero-width
7418 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7419 buffer positions that will be removed from the glyph row because
7421 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7422 column is beyond frame width: don't subtract 1 "pixel" when
7423 computing width of the stretch.
7424 (reseat_at_next_visible_line_start): Undo the change made on
7425 2011-09-17 that saved paragraph information and restored it after
7426 the call to `reseat'. (Bug#9545)
7428 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7430 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7431 and turn window cursor on if cleared (Bug#9415).
7433 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7435 * search.c (boyer_moore): Take unibyte characters from pattern
7436 literally. (Bug#9458)
7438 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7440 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7442 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7444 Fix minor problem found by static checking.
7445 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7446 initialized, to pacify gcc -Wuninitialized.
7448 * fileio.c: Report proper errno when syscall falls.
7449 (Finsert_file_contents): Save and restore errno,
7450 so that report_file_error outputs the correct diagnostic.
7451 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7453 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7455 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7457 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7459 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7460 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7462 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7464 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7465 about the current paragraph and restore it after the call to reseat.
7467 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7468 (bidi_find_paragraph_start): Search back for paragraph beginning
7469 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7470 (bidi_move_to_visually_next): Only trigger paragraph-related
7471 computations when the last character is a newline or at EOB, not
7472 just any NEUTRAL_B. (Bug#9470)
7474 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7475 truncated lines if point is covered by a display string. (Bug#9524)
7477 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7479 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7480 (cons_to_x_long): New function.
7481 (lisp_data_to_selection_data): Use it. Correct the test for
7482 short-versus-long data; it was negated. Break out of vector
7483 loop, for efficiency, when a long datum is discovered.
7485 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7487 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7489 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7491 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7492 GCC PR/17406) by declaring this function with external scope.
7494 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7496 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7497 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7499 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7501 * editfns.c (Fformat): Correctly handle text properties on "%%".
7503 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7505 * xterm.c (x_draw_composite_glyph_string_foreground):
7506 * w32term.c (x_draw_composite_glyph_string_foreground):
7507 * term.c (encode_terminal_code):
7508 * composite.c (composition_update_it, get_composition_id):
7509 * xdisp.c (get_next_display_element)
7510 (fill_composite_glyph_string): Add comments about special meaning
7511 of TAB characters in a composition.
7513 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7515 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7516 This occurs when processing a multibyte format.
7517 Problem reported by Wolfgang Jenker.
7519 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7521 * xdisp.c (try_cursor_movement): Only check for exact match if
7522 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7524 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7526 Remove unused external symbols.
7527 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7528 * xdisp.c (calc_pixel_width_or_height): Now static.
7529 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7530 * indent.c (check_display_width):
7531 * w32term.c: Fix comment to match code.
7532 * xterm.c, xterm.h (x_catching_errors): Remove.
7534 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7536 * xselect.c: Use signed conversions more consistently (Bug#9498).
7537 (selection_data_to_lisp_data): Assume incoming selection data are
7538 signed integers, not unsigned. This is to be consistent with
7539 outgoing selection data, which was modified to use signed integers
7540 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7541 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7542 expects long, not unsigned long.
7544 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7546 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7547 computation of loop end. Reported by Johan Bockgård
7550 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7552 * frame.c (Fother_visible_frames_p): Function deleted.
7554 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7556 * indent.c (compute_motion): Process display vector front to back
7557 rather than the other way around. (Bug#2496)
7559 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7561 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7563 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7565 * minibuf.c (Fread_from_minibuffer): Doc fix.
7567 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7569 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7570 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7572 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7574 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7575 value for non-existent files.
7577 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7579 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7580 set its "size" to -1. This will set the modtime_size field of
7581 the corresponding buffer to -1, which is what
7582 verify-visited-file-modtime expects for files that do not exist.
7585 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7587 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7589 * lisp.h: ... from here. push_key_description is no longer
7590 defined in keyboard.c, so its declaration should not be in
7591 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7592 logically belongs with push_key_description.
7594 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7596 * buffer.h: Include <sys/types.h> instead of <time.h>.
7597 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7598 Problem reported by Herbert J. Skuhra.
7600 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7602 * xml.c (parse_region): Make the parsing work for
7603 non-comment-starting XML files again (bug#9144).
7605 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7607 * image.c (gif_load): Fix calculation of bottom and right corner.
7610 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7612 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7613 redisplay in small windows.
7615 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7617 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7619 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7621 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7622 Operate on live windows only.
7624 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7626 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7628 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7630 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7631 only under bidi iteration.
7633 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7635 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7637 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7639 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7640 Without this fix, the command to link temacs failed due to an
7641 undefined symbol __builtin_isnan. This is because
7642 /usr/include/iso/math_c99.h #defines isnan(x) to
7643 __builtin_isnan(x), but the bundled gcc, which identifies itself
7644 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7646 * floatfns.c (isnan): #undef, and then #define to a clone of
7648 (Fisnan): Always define, since it's always available now.
7649 (syms_of_floatfns): Always define isnan at the Lisp level.
7651 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7653 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7655 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7657 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7658 The previous code assumed that file offsets (off_t values) fit in
7659 EMACS_INT variables, which is not true on typical 32-bit hosts.
7660 The code messed up by falsely reporting buffer overflow in cases
7661 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7662 when "big" contains more than 2**29 bytes, even though this
7663 inserts just one byte and does not overflow the buffer.
7664 (Finsert_file_contents): Store file offsets as off_t
7665 values, not as EMACS_INT values. Check for overflow when
7666 converting between EMACS_INT and off_t. When checking for
7667 buffer overflow or for overlap, take the offsets into account.
7668 Don't use EMACS_INT for small values where int suffices.
7669 When checking for overlap, fix a typo: ZV was used where
7670 ZV_BYTE was intended.
7671 (Fwrite_region): Don't assume off_t fits into 'long'.
7672 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7674 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7676 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7678 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7680 sprintf-related integer and memory overflow issues (Bug#9412).
7682 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7683 (esprintf, exprintf, evxprintf): New functions.
7684 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7685 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7686 (modify_event_symbol): Do not assume that the length of
7687 name_alist_or_stem is safe to alloca and fits in int.
7688 (Fexecute_extended_command): Likewise for function name and binding.
7689 (Frecursion_depth): Wrap around reliably on integer overflow.
7690 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7691 since some callers pass EMACS_INT values.
7692 (Fsingle_key_description): Don't crash if symbol name contains more
7693 than MAX_ALLOCA bytes.
7694 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7695 (get_minibuffer): Arg is now EMACS_INT, not int.
7696 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7697 (esprintf, exprintf, evxprintf): New decls.
7698 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7700 * dbusbind.c (signature_cat): New function.
7701 (xd_signature, Fdbus_register_signal):
7702 Do not overrun buffer; instead, report string overflow.
7704 * dispnew.c (add_window_display_history): Don't overrun buffer.
7705 Truncate instead; this is OK since it's just a log.
7707 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7708 even if the time zone offset is outlandishly large.
7709 Don't mishandle offset == INT_MIN.
7711 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7712 when creating daemon; the previous buffer-overflow check was incorrect.
7714 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7715 which has the guts of the old verror function.
7717 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7718 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7720 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7721 (font_unparse_xlfd): Don't blindly alloca long strings.
7722 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7723 fits in int, when using sprintf. Use single snprintf to count
7724 length of string rather than counting it via multiple sprintfs;
7725 that's simpler and more reliable.
7726 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7727 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7728 sprintf, in case result does not fit in int.
7730 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7731 (fontset_from_font): Print it.
7733 * frame.c (tty_frame_count): Now printmax_t, not int.
7734 (make_terminal_frame, set_term_frame_name): Print it.
7735 (x_report_frame_params): In X, window IDs are unsigned long,
7736 not signed long, so print them as unsigned.
7737 (validate_x_resource_name): Check for implausibly long names,
7738 and don't assume name length fits in 'int'.
7739 (x_get_resource_string): Don't blindly alloca invocation name;
7740 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7743 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7744 (xg_check_special_colors, xg_set_geometry):
7745 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7747 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7748 Use esprintf, not sprintf, in case result does not fit in int.
7750 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7751 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7752 it as a large positive number.
7753 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7754 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7756 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7757 in case result does not fit in int.
7759 * print.c (float_to_string): Detect width overflow more reliably.
7760 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7761 buffer overrun. Don't assume list length fits in 'int'. Treat
7762 print length of 0 as 0, not as infinity; to be consistent with other
7763 uses of print length in this function. Don't overflow print length
7764 index. Don't assume hash table size fits in 'long', or that
7765 vectorlike size fits in 'unsigned long'.
7767 * process.c (make_process): Use printmax_t, not int, to format
7768 process-name gensyms.
7770 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7772 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7773 to avoid potential buffer overrun.
7775 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7776 if X resource line is longer than 512 bytes.
7778 * xfns.c (x_window): Make sprintf buffer a bit bigger
7779 to avoid potential buffer overrun.
7781 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7785 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7787 Integer overflow fixes for scrolling, etc.
7788 Without these, Emacs silently mishandles large integers sometimes.
7789 For example, "C-u 4294967297 M-x recenter" was treated as if
7790 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7792 * xdisp.c (try_window_id): Check Emacs fixnum range before
7793 converting to 'int'.
7795 * window.c (window_scroll_line_based, Frecenter):
7796 Check that an Emacs fixnum is in range before assigning it to 'int'.
7797 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7798 values converted from Emacs fixnums.
7799 (Frecenter): Don't wrap around a line count if it is out of 'int'
7800 range; instead, treat it as an extreme value.
7801 (Fset_window_configuration, compare_window_configurations):
7802 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7804 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7805 that can exceed INT_MAX. Check that EMACS_INT value is in range
7806 before assigning it to the (possibly-narrower) index.
7807 (match_limit): Don't assume that a fixnum can fit in 'int'.
7809 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7812 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7813 (Fvertical_motion): Don't wrap around LINES values that don't fit
7814 in 'int'. Instead, treat them as extreme values. This is good
7815 enough for windows, which can't have more than INT_MAX lines anyway.
7817 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7819 * Require libxml/parser.h to avoid compilation warning.
7821 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7823 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7824 since this reportedly can destroy thread storage.
7826 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7828 * syntax.c (find_defun_start): Update all cache variables if
7829 exiting early (Bug#9401).
7831 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7833 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7835 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7836 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7837 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7839 * term.c (tty_append_glyph): New function.
7840 (produce_stretch_glyph): Static function and its prototype deleted.
7842 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7845 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7847 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7848 when checking :margin (Bug#9390).
7849 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7850 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7851 so that the name doesn't mislead. All uses changed.
7853 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7855 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7858 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7860 * xdisp.c (move_it_to): Don't bail out early when reaching
7861 position beyond to_charpos, if we are scanning backwards.
7862 (move_it_vertically_backward): When DY == 0, make sure we get to
7863 the first character in the line after the newline.
7865 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7867 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7868 (ccl_driver): Do not generate an out-of-range pointer.
7869 (Fccl_execute_on_string): Remove unnecessary check for
7870 integer overflow, noted by Stefan Monnier in
7871 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7872 Remove a FIXME that didn't need fixing.
7873 Simplify the newly-introduced buffer reallocation code.
7875 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7877 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7879 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7881 Integer and memory overflow issues (Bug#9196).
7883 * doc.c (get_doc_string): Rework so that
7884 get_doc_string_buffer_size is the actual buffer size, rather than
7885 being 1 less than the actual buffer size; this makes xpalloc more
7888 * image.c (x_allocate_bitmap_record, cache_image):
7889 * xselect.c (Fx_register_dnd_atom):
7890 Simplify previous changes by using xpalloc.
7892 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7893 since either will do and ptrdiff_t is convenient with xpalloc.
7895 * charset.c (charset_table_size)
7896 (struct charset_sort_data.priority): Now ptrdiff_t.
7897 (charset_compare): Don't overflow if priorities differ greatly.
7898 (Fsort_charsets): Don't assume list length fits in int.
7899 Check for size-calculation overflow when allocating sort data.
7900 (syms_of_charset): Allocate an initial charset table that is
7901 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7903 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7905 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7906 The actual value is always <= INT_MAX, and leaving it unsigned made
7907 overflow checking harder.
7909 * dispextern.h (struct glyph_matrix.rows_allocated)
7910 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7911 with xpalloc. The values are still always <= INT_MAX.
7913 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7915 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7916 (SAFE_NALLOCA): New macro.
7918 * region-cache.c (struct boundary.pos, find_cache_boundary)
7919 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7920 (set_cache_region, invalidate_region_cache)
7921 (revalidate_region_cache, know_region_cache, region_cache_forward)
7922 (region_cache_backward, pp_cache):
7923 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7924 so that ptrdiff_t * can be passed to xpalloc.
7925 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7926 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7927 (pp_cache): Don't assume cache_len fits in int.
7928 * region-cache.h: Adjust extern decls to match.
7930 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7931 EMACS_INT, since either will do, for xpalloc.
7933 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7934 (xnmalloc, xnrealloc, xpalloc): New functions.
7936 * bidi.c (bidi_shelve_header_size): New constant.
7937 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7938 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7940 * bidi.c (bidi_cache_shrink):
7941 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7943 Don't update size of array until after memory allocation succeeds,
7944 because xmalloc/xrealloc may not return.
7945 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7946 now that we have proper integer overflow checking.
7947 (record_overlay_string, overlay_strings): Catch overflows when
7948 calculating size of overlay_str_buf.
7950 * callproc.c (Fcall_process): Check for size overflow when
7951 calculating size of args2.
7952 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7953 Normally we prefer signed values, but sticking with ptrdiff_t would
7954 require adding more-complicated checks.
7956 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7957 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7958 Redo buffer-overflow calculations to avoid integer overflow.
7959 Add a FIXME comment where memory seems to be over-allocated.
7961 * character.c (Fstring): Check for size-calculation overflow.
7963 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7964 unnecessary integer overflow. Check for size overflow.
7965 (encode_coding_object): Don't update size until xmalloc succeeds.
7967 * composite.c (get_composition_id): Check for overflow in glyph
7968 length calculations.
7970 Integer and memory overflow fixes for display code.
7971 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7972 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7973 (scrolling_window): Check for overflow in size calculations.
7974 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7978 (scrolling_window): Avoid overflow in size calculations.
7979 Don't update size until allocation succeeds.

7985 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7986 (get_doc_string): Check for size calculation overflow.
7987 Don't update size until allocation succeeds.
7988 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7989 EMACS_INT, where ptrdiff_t will do.
7990 (Fsubstitute_command_keys): Check for string overflow.
7992 * editfns.c (set_time_zone_rule): Don't assume environment length
7994 (message_length): Now ptrdiff_t, not int.
7995 (Fmessage_box): Don't update size until allocation succeeds.
7996 Don't assume message length fits in int.
7997 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7999 * emacs.c (main): Do not reallocate argv, since there is a null at
8000 the end that can be overwritten, and this way there's no need to
8001 worry about size-calculation overflow.
8002 (sort_args): Check for size-calculation overflow.
8004 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8006 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8008 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8009 (x_set_scroll_bar_width, x_figure_window_size):
8010 Check for integer overflow.
8011 (x_set_alpha): Do not assume XINT fits in int.
8013 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8014 This is for the members text_lines, text_cols, total_lines, total_cols,
8015 where the system imposes an 'int' limit.
8017 * fringe.c (Fdefine_fringe_bitmap):
8018 Don't update size until alloc works.
8020 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8021 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8023 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8024 Check for size-calculation overflow.
8025 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8026 do, as we prefer signed integers.
8027 (id_to_widget.max_size, id_to_widget.used)
8028 (xg_store_widget_in_map, xg_remove_widget_from_map)
8029 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8030 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8031 Use and return ptrdiff_t, not int.
8032 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8033 * gtkutil.h: Change prototypes to match the above.
8035 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8036 are duplicate now that they've been promoted to lisp.h.
8037 (x_allocate_bitmap_record, x_alloc_image_color)
8038 (make_image_cache, cache_image, xpm_load):
8039 Don't update size until alloc is done.
8040 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8042 Check for size calculation overflow.
8043 (ct_colors_allocated_max): New constant.
8044 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

8049 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8050 Use ptrdiff_t, not int, to count maps.
8051 (read_char_minibuf_menu_prompt): Check for overflow in size
8052 calculations. Don't update size until allocation succeeds.

8064 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8066 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8067 Now ptrdiff_t, not int.
8068 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

8079 * search.c (Freplace_match): Check for size calculation overflow.
8080 (Fset_match_data): Don't assume list lengths fit in 'int'.
8082 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8083 for command line length. Do not attempt to address one before the
8084 beginning of an array, as that's not portable.

8087 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8089 (encode_terminal_code, calculate_costs): Check for size
8090 calculation overflow.

8092 table lengths and related sizes. Don't update size until alloc
8093 done. Redo calculations to avoid overflow.
8094 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8096 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

8112 Use ptrdiff_t, not int, for sizes.
8113 (Finternal_make_lisp_face, cache_face):
8114 Check for size calculation overflow.
8115 (cache_face): Treat size calculation overflows as if they were
8116 memory exhaustion (the usual treatment), rather than aborting.
8118 * xfns.c (x_encode_text, x_set_name_internal)
8119 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8120 sizes, since they can exceed INT_MAX in size. Check for size
8121 calculation overflow.
8123 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8124 (xg_select): Check for size calculation overflow.
8125 Don't update size until alloc done.
8127 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8128 as sprintf is limited to int lengths.
8130 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8131 (X_LONG_MIN): New macros.
8132 Use them to make the following changes clearer.
8133 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8134 This change doesn't affect the value now, but it may help remind
8135 future maintainers not to raise the value too much later.
8136 (SELECTION_QUANTUM): Remove, replacing with ...
8137 (selection_quantum): ... new function, which avoids overflow.
8139 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8140 assumption that selection length fits in 'int'.
8141 (x_reply_selection_request, x_handle_selection_request)
8142 (x_get_window_property, receive_incremental_selection)
8143 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8144 (lisp_data_to_selection_data, clean_local_selection_data):
8145 Use ptrdiff_t, not int, to record length of selection.
8146 (x_reply_selection_request, x_get_window_property)
8147 (receive_incremental_selection, x_property_data_to_lisp):
8148 Redo calculations to avoid overflow.
8149 (x_reply_selection_request): When sending hint, ceiling it at
8150 X_LONG_MAX rather than relying on wraparound overflow to send
8152 (x_get_window_property, receive_incremental_selection)
8153 (lisp_data_to_selection_data, x_property_data_to_lisp):
8154 Check for size-calculation overflow.
8155 (x_get_window_property, receive_incremental_selection)

8157 Don't store size until memory allocation succeeds.
8158 (x_get_window_property): Plug memory leak on memory exhaustion.
8159 Don't double-block input; malloc is safe here. Don't assume 2**34
8160 - 4 fits in unsigned long. Add an xassert to check
8161 XGetWindowProperty overflow. Be more careful about overflow
8162 calculations, and distinguish size from memory overflow better.
8163 (receive_incremental_selection): When tracing, don't assume
8164 unsigned int is less than INT_MAX.
8165 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8166 harmful) conversions of unsigned short to int.
8167 (lisp_data_to_selection_data): Don't assume that integers
8168 in the range -65535 through -1 fit in an X unsigned short.
8169 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8170 result parameters unless successful. Rely on cons_to_unsigned
8171 to report problems with elements; the old code wasn't right anyway.
8172 (x_check_property_data): Check for int overflow; we cannot use
8173 a wider type due to X limits.
8174 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8206 * lisp.h (hash_lookup, hash_put):
8207 * minibuf.c (Ftest_completion):
8208 Use ptrdiff_t for hash table indexes, not int (which is too
8209 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8210 32-bit --with-wide-int hosts).
8212 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8213 Add a FIXME comment about memory leaks.
8214 (syms_of_charset): Don't assume xmalloc returns.
8216 Don't assume that stated character widths fit in int.

8218 * character.h (CHAR_WIDTH):
8219 * indent.c (MULTIBYTE_BYTES_WIDTH):
8220 Use sanitize_char_width to avoid undefined and/or bad behavior
8221 with outlandish widths.
8222 * character.h (sanitize_tab_width): Rename from sanitize_width,
8223 now that we have two such functions. All uses changed.
8224 (sanitize_char_width): New inline function.

8242 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8243 (x_send_scroll_bar_event): Likewise. Check that the size does not
8244 exceed limits imposed by XClientMessageEvent, as well as the usual
8245 ptrdiff_t and size_t limits.
8247 * keyboard.c: Overflow, signedness and related fixes.
8248 (make_lispy_movement): Use same integer type in forward decl
8249 that is used in the definition.
8250 (read_key_sequence, keyremap_step):
8251 Change bufsize argument back to int, undoing my 2011-03-30 change.
8252 We prefer signed types, and int is wide enough here.
8253 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8254 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8255 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8256 length, not size_t. Use ptrdiff_t for index, not int.
8257 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8258 possibility of integer overflow.
8260 Overflow, signedness and related fixes for images.

8281 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8282 (lookup_image): Remove unnecessary tests.
8283 (xbm_image_p): Locals are now of int, not EMACS_INT,
8284 since parse_image_check makes sure they fit into int.
8285 (png_load, gif_load, svg_load_image):
8286 Prefer int to unsigned where either will do.
8287 (tiff_handler): New function, combining the cores of the
8288 old tiff_error_handler and tiff_warning_handler.
8289 This function is rewritten to use vsnprintf and thereby avoid
8290 stack buffer overflows. It uses only the features of vsnprintf
8291 that are common to both POSIX and native Microsoft.
8292 (tiff_error_handler, tiff_warning_handler): Use it.
8293 (tiff_load, gif_load, imagemagick_load_image):
8294 Don't assume :index value fits in 'int'.
8295 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8296 (imagemagick_load_image): Check that crop parameters fit into
8297 the integer types that MagickCropImage accepts. Don't assume
8298 Vimagemagick_render_type has a nonnegative value. Don't assume
8299 size_t fits in 'long'.
8300 (gs_load): Use printmax_t to print the widest integers possible.

8311 the display spec is of the form `(space ...)'.
8312 (handle_display_spec): Return the value returned by
8313 handle_single_display_spec, not just 1 or zero.
8314 (handle_single_display_spec): If the display spec is of the form
8315 `(space ...)', and specifies display in the text area, return 2
8317 (try_cursor_movement): Check for the need to scroll more
8318 accurately, and prefer exact match for point under bidi.
8319 Don't advance `row' beyond the last row of the window.
8321 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8322 into disp_prop; all users changed.
8324 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8337 buffers, return left-to-right.
8338 (set_cursor_from_row): Consider candidate row a win if its glyph
8339 represents a newline and point is on that newline. Fixes cursor
8340 positioning on the newline at EOL of R2L text within L2R
8341 paragraph, and vice versa.
8342 (try_cursor_movement): Check continued rows, in addition to
8343 continuation rows. Fixes unwarranted scroll when point enters a
8344 continued line of R2L text within an L2R paragraph, or vice versa.
8345 (cursor_row_p): Consider the case of point being equal to
8346 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8347 from the end of a short line to the beginning of a continued line
8348 of R2L text within L2R paragraph.
8349 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8350 composed characters.
8352 * bidi.c (bidi_check_type): Use xassert.

8365 2011-08-22 Kenichi Handa <handa@m17n.org>
8367 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8368 extra slot even if the purpose is char-code-property-table.
8370 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8372 * xdisp.c (redisplay_window): When computing centering_position,
8373 account for the height of the header line. (Bug#8874)
8375 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8376 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8377 candidate is selected by the mouse, and that candidate has a
8378 composed character under the mouse.
8380 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8381 coordinates reported by pos-visible-in-window-p for a composed
8382 character in column zero.
8384 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

8388 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8390 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8391 consider it a hit if to_charpos is anywhere in the range of the
8392 composed buffer positions.
8394 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8396 * image.c (gif_load): Don't assume that each subimage has the same
8397 dimensions as the base image. Handle disposal method that is
8398 "undefined" by the gif spec (Bug#9335).
8400 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8402 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8405 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8407 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8408 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8409 from an Org mode buffer to a Speedbar frame.
8411 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8412 a composition, take its buffer position from IT->cmp_it.charpos.
8413 Fixes cursor positioning at the beginning of a line that begins
8414 with a composed character.
8416 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8418 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8419 character bidirectional type, use STRONG_L instead. Fixes crashes
8420 in a buffer produced by `describe-categories'.
8422 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8423 members before the level stack, so they would be saved and
8424 restored when copying iterator state. Fixes incorrect reordering
8425 around TABs covered by display properties.
8427 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8429 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8437 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8439 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8440 has no `load' handler, try opening the file locally. (Bug#9311)
8442 2011-08-16 Ken Brown <kbrown@cornell.edu>

8499 * xdisp.c (move_it_in_display_line_to): Don't invoke
8500 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8501 ppos_it. Fixes vertical cursor motion when line beginning is
8502 covered by an image. (Bug#9296)
8504 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8506 * nsterm.h (ns_run_ascript): Declare.

8509 * nsfns.m (as_script, as_result, as_status): New static variables.
8510 (ns_run_ascript): New function.
8511 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8512 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8513 the event loop. Get status from as_status (Bug#7276).
8515 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8516 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8517 the event loop (Bug#7276).

8543 (Fnetwork_interface_list): Allocate in increments of bytes instead
8544 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8545 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8547 (struct ifflag_def): notrailers is smart on OSX.
8548 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8549 Get hardware address with getifaddrs if available.
8551 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8553 * xdisp.c (iterate_out_of_display_property): xassert that
8554 IT->position is set to within IT->object's boundaries. Break from
8555 the loop as soon as EOB is reached; avoids infloops in redisplay
8556 when IT->position is set up wrongly due to some bug.
8557 Set IT->current to match the bidi iterator unconditionally.
8558 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8559 entry. Force push_it to save on the stack the current
8560 buffer/string position, to be restored by pop_it. Fix flags in
8561 the iterator structure wrt the object coming from a display
8562 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8563 properties. (Bug#9284)
8565 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8567 * fontset.c (fontset_get_font_group): Add proper type checks.

8575 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8577 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8579 * xdisp.c (forward_to_next_line_start): Allow to use the
8580 no-display-properties-and-no-overlays under bidi display.
8581 Set disp_pos in the bidi iterator to avoid searches for display
8582 properties and overlays.
8584 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8586 * editfns.c (Fset_time_zone_rule): Document relationship with the

8592 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8594 * composite.c (autocmp_chars): Don't reset point. That is done by
8595 restore_point_unwind (Bug#5984).
8597 2011-08-07 Juri Linkov <juri@jurta.org>
8599 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8600 to show the arg `TIME' instead of `TIMEVAL'.
8602 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8604 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8605 display property strides EOL and includes a newline, as in
8606 longlines-mode. (Bug#9254)
8607 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8608 word-wrap under bidirectional display. (Bug#9224)
8610 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8611 is non-zero, even if the data buffer is NULL. Fixes a crash in
8612 vertical-motion with longlines-mode. (Bug#9254)
8614 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8616 * bidi.c <bidi_cache_total_alloc>: Now static.
8617 (bidi_initialize): Initialize bidi_cache_total_alloc.
8619 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8622 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8623 amount allocated this far in `bidi_cache_total_alloc'.
8624 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8625 non-zero, only free the data buffer without restoring the cache
8626 contents. All callers changed.
8628 * dispextern.h (bidi_unshelve_cache): Update prototype.
8630 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8631 (move_it_in_display_line, move_it_to)
8632 (move_it_vertically_backward, move_it_by_lines): Replace the call
8633 to xfree to an equivalent call to bidi_unshelve_cache.
8634 (move_it_in_display_line_to): Fix logic of returning
8635 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8637 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8639 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8640 came from a string character with a `cursor' property. (Bug#9229)

8658 x_find_topmost_parent and set the property there also (bug#9181).
8659 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8661 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8663 * callproc.c (Fcall_process): Avoid vfork clobbering
8664 the local vars buffer, coding_systems, current_dir.
8666 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8668 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8670 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8672 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8673 so that it is not optimized away.
8675 * xdisp.c (compute_display_string_pos): Remove unused local.
8677 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8679 Fix slow cursor motion and scrolling in large buffers with
8680 selective display, like Org Mode buffers. (Bug#9218)
8682 * dispextern.h (struct bidi_it): New member disp_prop_p.
8684 * xdisp.c: Remove one-slot cache of display string positions.
8685 (compute_display_string_pos): Accept an additional argument
8686 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8687 for a display string or property. If found, set DISP_PROP_P
8690 * bidi.c (bidi_fetch_char): Accept an additional argument
8691 DISP_PROP_P, and pass it to compute_display_string_pos.
8692 Only handle text covered by a display string if DISP_PROP_P is returned
8693 non-zero. All callers of bidi_fetch_char changed.
8695 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8697 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8699 2010-12-03 Don March <don@ohspite.net>
8701 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8702 last character M-[char] is translated to ESC [char] (bug#7541).
8704 2011-08-02 Kenichi Handa <handa@m17n.org>
8706 * lisp.h (uniprop_table): Extern it.
8708 * chartab.c (uniprop_table): Make it non-static.
8710 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8712 * xdisp.c (forward_to_next_line_start): Accept additional argument
8713 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8715 (reseat_at_next_visible_line_start): Use the bidi iterator state
8716 returned by forward_to_next_line_start to restore the state of
8717 it->bidi_it after backing up to previous newline. (Bug#9212)
8719 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8721 * regex.c (re_comp): Protoize.
8722 (re_exec): Fix return type.
8723 (regexec): Fix type of `ret'. (Bug#9203)
8725 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8727 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8728 This is needed if max-image-size is a floating-point number.
8730 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8732 * print.c (print_object): Print empty symbol as ##.
8734 * lread.c (read1): Read ## as empty symbol.
8736 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8738 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8739 setting frame foreground color (Bug#9175).
8740 (x_set_background_color): Likewise.
8742 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8743 contents (Bug#9176).
8744 (EmacsTooltip -init): Remove bezels and add shadows to
8747 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8748 or scroll bar (Bug#8470).
8750 * nsfont.m (nsfont_open): Remove assignment to voffset and
8751 unnecessary vars hshink, expand, hd, full_height, min_height.
8752 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8754 * nsterm.h (nsfont_info): Remove voffset field.
8756 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8758 Implement strike-through and overline on NextStep (Bug#8863).
8760 * nsfont.m (nsfont_open): Use underline position provided by font,
8761 instead of hard-coded value of 2.
8762 (nsfont_draw): Call ns_draw_text_decoration instead.
8764 * nsterm.h: Add declaration for ns_draw_text_decoration.
8766 * nsterm.m (ns_draw_text_decoration): New function for drawing
8767 underline, overline, and strike-through.
8768 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8769 ns_draw_text_decoration. Change treatment of cursor drawing to
8770 accommodate underlining, etc.
8772 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8774 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8777 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8779 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8780 Without this fix, if a signal arrives just after memory fills up,
8781 'malloc' might be invoked reentrantly.
8783 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8784 In other words, assume that every image size is allowed, on non-X
8785 hosts. This assumption is probably wrong, but it lets Emacs compile.
8787 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8789 * regex.c (re_iswctype): Convert return values to boolean.
8791 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8793 * xdisp.c (compute_display_string_pos): Don't use cached display
8794 string position if the buffer had its restriction changed.
8797 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8799 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8801 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8803 Integer signedness and overflow and related fixes. (Bug#9079)
8805 * bidi.c: Integer size and overflow fixes.
8806 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8807 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8808 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8809 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8810 (bidi_find_other_level_edge):
8811 Use ptrdiff_t instead of EMACS_INT where either will do.
8812 This works better on 32-bit hosts configured --with-wide-int.
8813 (bidi_cache_ensure_space): Check for size-calculation overflow.
8814 Use % rather than repeated addition, for better worst-case speed.
8815 Don't set bidi_cache_size until after xrealloc returns, because it
8817 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8818 (bidi_cache_ensure_space): Also check that the bidi cache size
8819 does not exceed that of the largest Lisp string or buffer. See Eli
8820 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8822 * alloc.c (__malloc_size_t): Remove.
8823 All uses replaced by size_t. See Andreas Schwab's note
8824 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8826 * image.c: Improve checking for integer overflow.
8827 (check_image_size): Assume that f is nonnull, since
8828 it is always nonnull in practice. This is one less thing to
8829 worry about when checking for integer overflow later.
8830 (x_check_image_size): New function, which checks for integer
8831 overflow issues inside X.
8832 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8833 This removes the need for a memory_full check.
8834 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8835 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8836 (xbm_read_bitmap_data): Change locals back to 'int', since
8837 their values must fit in 'int'.
8838 (xpm_load_image, png_load, tiff_load):
8839 Invoke x_create_x_image_and_pixmap earlier,
8840 to avoid much needless work if the image is too large.
8841 (tiff_load): Treat overly large images as if
8842 x_create_x_image_and_pixmap failed, not as malloc failures.
8843 (gs_load): Use x_check_image_size.
8845 * gtkutil.c: Omit integer casts.
8846 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8847 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8849 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8851 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8852 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8853 would wrongly return t on a 64-bit host.
8855 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8856 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8857 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8858 and therefore cause GCC to emit a bogus diagnostic in some cases.
8860 * image.c: Integer signedness and overflow and related fixes.
8861 This is not an exhaustive set of fixes, but it's time to
8862 record what I've got.
8863 (lookup_pixel_color, check_image_size): Remove redundant decls.
8864 (check_image_size): Don't assume that arbitrary EMACS_INT values
8865 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8866 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8867 (tiff_load, imagemagick_load_image):
8868 Check for overflow in size calculations.
8869 (x_create_x_image_and_pixmap): Remove unnecessary test for
8870 xmalloc returning NULL; that can't happen.
8871 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8872 (xpm_color_bucket): Use better integer hashing function.
8873 (xpm_cache_color): Don't possibly over-allocate memory.
8874 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8875 (gif_memory_source):
8876 Use ptrdiff_t, not int or size_t, to record sizes.
8877 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8878 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8879 either works, as we prefer signed integers.
8880 (tiff_read_from_memory, tiff_write_from_memory):
8881 Return tsize_t, not size_t, since that's what the TIFF API wants.
8882 (tiff_read_from_memory): Don't fail simply because the read would
8883 go past EOF; instead, return a short read.
8884 (tiff_load): Omit no-longer-needed casts.
8885 (Fimagemagick_types): Don't assume size fits into 'int'.
8887 Improve hashing quality when configured --with-wide-int.
8888 * fns.c (hash_string): New function, taken from sxhash_string.
8889 Do not discard information about ASCII character case; this
8890 discarding is no longer needed.
8891 (sxhash-string): Use it. Change sig to match it. Caller changed.
8892 * lisp.h: Declare it.
8893 * lread.c (hash_string): Remove, since we now use fns.c's version.
8894 The fns.c version returns a wider integer if --with-wide-int is
8895 specified, so this should help the quality of the hashing a bit.
8897 * emacs.c: Integer overflow minor fix.
8898 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8899 Define only if GNU_LINUX.
8900 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8902 * dispnew.c: Integer signedness and overflow fixes.
8903 Remove unnecessary forward decls, that were a maintenance hassle.
8904 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8906 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8907 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8908 (prepare_desired_row, line_draw_cost):
8909 Use int, not unsigned, where either works.
8910 (save_current_matrix, restore_current_matrix):
8911 Use ptrdiff_t, not size_t, where either works.
8912 (init_display): Check for overflow more accurately, and without
8913 relying on undefined behavior.
8915 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8916 Remove, replacing with the new symbols in lisp.h. All uses changed.
8917 * fileio.c (make_temp_name):
8918 * filelock.c (lock_file_1, lock_file):
8919 * xdisp.c (message_dolog):
8920 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8921 Use pMd etc. instead.
8922 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8923 replacing the pWIDE etc. symbols removed from editfns.c.
8925 * keyboard.h (num_input_events): Now uintmax_t.
8926 This is (very slightly) less likely to mess up due to wraparound.
8929 * buffer.c: Integer signedness fixes.
8930 (alloc_buffer_text, enlarge_buffer_text):
8931 Use ptrdiff_t rather than size_t when either will do, as we prefer
8934 * alloc.c: Integer signedness and overflow fixes.
8935 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8936 (__malloc_size_t): Default to size_t, not to int.
8937 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8938 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8939 Prefer ptrdiff_t to size_t when either would do, as we prefer
8941 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8942 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8943 Now const. Initialize with values that are in range even if char
8945 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8946 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8947 These functions do the right thing with sizes > 2**32.
8948 (check_depth): Now ptrdiff_t, not int.
8949 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8950 Adjust to new way of storing sizes. Check for size overflow bugs
8952 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8953 slightly wrong anyway, as it missed one instance of
8954 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8955 (refill_memory_reserve): Omit needless cast to size_t.
8956 (mark_object_loop_halt): Mark as externally visible.
8958 * xselect.c: Integer signedness and overflow fixes.
8959 (Fx_register_dnd_atom, x_handle_dnd_message):
8960 Use ptrdiff_t, not size_t, since we prefer signed.
8961 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8962 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8963 x_dnd_atoms_size and x_dnd_atoms_length.
8965 * doprnt.c: Prefer signed to unsigned when either works.
8967 * doprnt.c (doprnt):
8969 * xdisp.c (vmessage):
8970 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8971 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8972 prefer signed arithmetic to avoid comparison confusion.
8973 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8974 but is a bit tricky.
8976 Assume freestanding C89 headers, string.h, stdlib.h.
8977 * data.c, doprnt.c, floatfns.c, print.c:
8978 Include float.h unconditionally.
8979 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8980 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8981 * regex.c: Likewise for stddef.h, string.h.
8982 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8983 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8984 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8985 (STDC_HEADERS): Remove obsolete defines.
8986 * sysdep.c: Include limits.h unconditionally.
8988 Assume support for memcmp, memcpy, memmove, memset.
8989 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8990 * regex.c (memcmp, memcpy):
8991 Remove; we assume C89 now.
8993 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8994 (__malloc_safe_bcopy): Remove; no longer needed.
8996 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8997 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8998 well either way, and we prefer signed to unsigned.
9000 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9002 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9003 closes the connection while we're reading (bug#9182).
9005 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9007 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9008 are specified (Bug#9168).
9010 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9012 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9013 Found by GCC static checking and --with-wide-int on a 32-bit host.
9015 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9017 * xdisp.c (compute_display_string_pos): Fix logic of caching
9018 previous display string position. Initialize cached_prev_pos to
9019 -1. Fixes slow-down at the beginning of a buffer.
9021 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9023 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9024 for attrs[LFACE_FONTSET_INDEX].
9026 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9028 * xml.c (parse_region): Remove unused local
9029 that was recently introduced.
9031 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9033 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9034 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9036 * xdisp.c (move_it_in_display_line_to): Record the best matching
9037 position for TO_CHARPOS while scanning the line, and restore it on
9038 exit if none of the characters scanned was an exact match.
9039 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9040 when exact match is impossible due to invisible text, and the
9041 lines are truncated.
9043 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9045 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9048 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9050 Fix a significant slow-down of cursor motion with C-n, C-p,
9051 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9052 auto-repeat under bidi redisplay in fontified buffers.
9053 * xdisp.c (compute_stop_pos_backwards): New function.
9054 (next_element_from_buffer): Call compute_stop_pos_backwards to
9055 find a suitable prev_stop when we find ourselves before
9057 (reseat): Don't look for prev_stop, as that could mean a very long
9059 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9060 <cached_disp_overlay_modiff>: Cache for last found display string
9062 (compute_display_string_pos): Return the cached position if asked
9063 about the same buffer in the same area of character positions, and
9064 the buffer wasn't changed since the time the display string
9065 position was cached.
9067 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9069 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9070 is an integer, which is important for empty lines. (Bug#9149)
9072 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9074 * frame.c (Fmodify_frame_parameters): In tty case, update the
9075 default face if necessary (Bug#4238).
9077 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9079 * editfns.c (Fstring_to_char): No need to explain what a character
9080 is in the docstring (Bug#6576).
9082 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9084 * xml.c (parse_region): Make sure we always return a tree.
9086 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9088 * xml.c (parse_region): If a document contains only comments,
9091 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9093 * xml.c (make_dom): Return comments, too.
9095 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9098 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9099 and the surrounding thread.
9100 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9101 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9102 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9104 * s/openbsd.h (BROKEN_SIGIO): Define.
9105 * unexelf.c (unexec) [__OpenBSD__]:
9106 Don't update the .mdebug section of the Alpha COFF symbol table.
9108 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9110 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9113 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9115 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9116 This fixes some race conditions on the permissions of any newly
9119 * alloc.c (valid_pointer_p): Use pipe, not open.
9120 This fixes some permissions issues when debugging.
9122 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9123 If fchown fails to set both uid and gid, try to set just gid,
9124 as that is sometimes allowed. Adjust the file's mode to eliminate
9125 setuid or setgid bits that are inappropriate if fchown fails.

9143 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9145 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9146 This works around a problem with the previous change to Fcopy_file.
9147 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9148 and without this change, GCC might complain about discarding
9149 fchown's return value.
9151 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9153 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

9178 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9179 quotes the next character, and doesn't affect other longer
9180 sequences (bug#8935).

9194 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9195 (elsz): Now a signed constant, not a size_t var. We prefer signed
9196 types to unsigned, to avoid integer comparison confusion. Without
9197 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9198 "cannot optimize loop, the loop counter may overflow", a symptom
9200 * indent.c (Fvertical_motion): Mark locals as initialized.
9201 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9203 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9205 * search.c (Fre_search_backward): Mention `case-fold-search' in
9206 all the re_search_* functions (bug#8138).

9247 the iterator is before prev_stop.
9248 (init_iterator): Initialize bidi_p from the default value of
9249 bidi-display-reordering, not from buffer-local value. Use the
9250 buffer-local value only if initializing for buffer iteration.

9766 Random fixes. E.g., (random) never returned negative values.
9767 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9768 subseconds part to the entropy, as that's a bit more random.
9769 Prefer signed to unsigned, since the signedness doesn't matter and
9770 in general we prefer signed. When given a limit, use a
9771 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9772 latter isn't right if USE_2_TAGS_FOR_INTS.
9773 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9774 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9787 This is more efficient than Ffile_directory_p and avoids a minor race.
9789 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9791 * buffer.c (Foverlay_put): Say what the return value is
9794 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9798 error be more correct.
9800 * fns.c (Frequire): Remove the mention of the .gz files, since
9801 that's installation-specific, but keep the mention of

9806 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9817 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9919 * eval.c (struct backtrace): Simplify and port the data structure.
9920 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9921 signed bit field, as this assumption is not portable and it makes
9922 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9923 "char debug_on_exit : 1" as this is not portable either; instead,
9924 use the portable "unsigned int debug_on_exit : 1". Remove unused

10089 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10091 Integer and buffer overflow fixes (Bug#8873).
10093 * print.c (printchar, strout): Check for string overflow.
10094 (PRINTPREPARE, printchar, strout):
10095 Don't set size unless allocation succeeds.
10097 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10098 for sizes. Check for string overflow more accurately.
10099 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10101 * macros.c: Integer and buffer overflow fixes.
10102 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10103 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10104 Use ptrdiff_t, not int, for sizes.
10105 Don't increment bufsize until after realloc succeeds.
10106 Check for size-calculation overflow.
10107 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10109 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10111 * lread.c: Integer overflow fixes.
10112 (read_integer): Radix is now EMACS_INT, not int,
10113 to improve quality of diagnostics for out-of-range radices.
10114 Calculate buffer size correctly for out-of-range radices.
10115 (read1): Check for integer overflow in radices, and in
10116 read-circle numbers.
10117 (read_escape): Avoid int overflow.
10118 (Fload, openp, read_buffer_size, read1)
10119 (substitute_object_recurse, read_vector, read_list, map_obarray):
10120 Use ptrdiff_t, not int, for sizes.
10121 (read1): Use EMACS_INT, not int, for sizes.
10122 Check for size overflow.
10124 * image.c (cache_image): Check for size arithmetic overflow.
10126 * lread.c: Integer overflow issues.
10127 (saved_doc_string_size, saved_doc_string_length)
10128 (prev_saved_doc_string_size, prev_saved_doc_string_length):
10129 Now ptrdiff_t, not int.

10131 out-of-range doc string lengths.
10132 (read_list): Don't assume file position fits in int.
10133 (read_escape): Check for hex character overflow.
10135 2011-06-22 Leo Liu <sdl.web@gmail.com>
10137 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10138 Move to minibuffer.el.
10140 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10142 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10143 The following patches are for when GLYPH_DEBUG && !XASSERT.
10144 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10145 * dispnew.c (flush_stdout):
10146 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10147 Mark as externally visible.
10148 * dispnew.c (check_window_matrix_pointers): Now static.
10149 * dispnew.c (window_to_frame_vpos):
10150 * xfns.c (unwind_create_frame):
10151 * xterm.c (x_check_font): Remove unused local.
10152 * scroll.c (CHECK_BOUNDS):
10153 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10154 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10155 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10156 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10157 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10159 (debug_method_add): Use va_list and vsprintf rather than relying
10160 on undefined behavior with wrong number of arguments.
10161 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10162 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10163 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10164 since we're not interested in debugging glyphs with old libraries.
10165 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10166 GCC 4.6.0's static checking.
10168 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10170 Integer overflow and signedness fixes (Bug#8873).

10179 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10180 (x_create_bitmap_from_xpm_data):
10181 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10182 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10184 * xfaces.c (load_pixmap):
10185 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10186 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10187 (.bitmaps_last, struct x_output.icon_bitmap):
10188 Use ptrdiff_t, not int, for bitmap indexes.
10189 (x_allocate_bitmap_record): Check for size overflow.
10190 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10192 Use ptrdiff_t, not int, for overlay counts.
10193 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10194 * editfns.c (overlays_around, get_pos_property):
10195 * textprop.c (get_char_property_and_overlay):
10196 * xdisp.c (next_overlay_change, note_mouse_highlight):
10197 * xfaces.c (face_at_buffer_position):
10198 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10199 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10200 (Fnext_overlay_change, Fprevious_overlay_change)
10201 (mouse_face_overlay_overlaps, Foverlays_in):
10202 Use ptrdiff_t, not int, for sizes.
10203 (overlays_at, overlays_in): Check for size-calculation overflow.
10205 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10207 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10208 (x_session_initialize): Do not assume string length fits in int.
10210 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10211 This is unlikely, but can occur if DPI is outlandish.
10213 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10214 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10216 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10217 * xrdb.c (magic_file_p, search_magic_path):
10218 Omit last arg SUFFIX; it was always 0. All callers changed.
10219 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10221 * xfont.c (xfont_match): Avoid need for strlen.
10223 * xfns.c: Don't assume strlen fits in int.
10224 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10226 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10227 not unsigned long, as we prefer signed integers. All callers changed.
10228 Detect integer overflow in repeat count.
10229 (message_dolog): Don't assume print length fits in 39 bytes.
10230 (display_mode_element): Don't assume strlen fits in int.
10232 * termcap.c: Don't assume sizes fit in int and never overflow.
10233 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10234 (gobble_line): Check for size-calculation overflow.
10236 * minibuf.c (Fread_buffer):
10237 * lread.c (intern, intern_c_string):
10238 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10239 Don't assume string length fits in int.
10241 * keyboard.c (parse_tool_bar_item):
10242 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10244 * font.c: Don't assume string length fits in int.
10245 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10246 Use ptrdiff_t, not int.
10247 (font_intern_prop): Don't assume string length fits in int.
10248 Don't assume integer property fits in fixnum.
10249 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10251 * filelock.c: Fix some buffer overrun and integer overflow issues.
10252 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10253 Reformulate so as not to need the command string.
10254 Invoke gzip -cd rather than gunzip, as it's more portable.
10255 (lock_info_type, lock_file_1, lock_file):
10256 Don't assume pid_t and time_t fit in unsigned long.
10257 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10258 (current_lock_owner): Prefer signed type for sizes.
10259 Use memcpy, not strncpy, where memcpy is what is really wanted.
10260 Don't assume (via atoi) that time_t and pid_t fit in int.
10261 Check for time_t and/or pid_t out of range, e.g., via a network share.
10262 Don't alloca where an auto var works fine.
10264 * fileio.c: Fix some integer overflow issues.
10265 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10266 Don't assume string length fits in int.
10267 (directory_file_name): Don't assume string length fits in long.
10268 (make_temp_name): Don't assume pid fits in int, or that its print
10269 length is less than 20.
10271 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10273 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10275 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10277 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10278 We prefer signed integers, even for size calculations.
10280 * emacs.c: Don't assume string length fits in 'int'.
10281 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10282 (main): Don't invoke strlen when not needed.
10284 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10285 (XD_DEBUG_MESSAGE): Don't waste a byte.
10287 * callproc.c (getenv_internal_1, getenv_internal)
10288 (Fgetenv_internal):
10289 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10291 * lread.c (invalid_syntax): Omit length argument.
10292 All uses changed. This doesn't fix a bug, but it simplifies the
10293 code away from its former Hollerith-constant appearance, and it's
10294 one less 'int' to worry about when looking at integer-overflow issues.
10295 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10297 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10298 This didn't break anything, but it didn't help either.
10299 It's confusing to put a bogus integer in a place where the actual
10300 value does not matter.
10301 (LIST_END_P): Remove unused macro and its bogus comment.
10302 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10304 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10305 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10307 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10308 We prefer signed types, and the value cannot exceed the EMACS_INT
10309 range anyway (because otherwise the length would not be representable).
10310 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10311 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10312 This avoids a GCC warning when WIDE_EMACS_INT.
10314 * indent.c (sane_tab_width): New function.
10315 (current_column, scan_for_column, Findent_to, position_indentation)
10316 (compute_motion): Use it. This is just for clarity.
10317 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10319 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10321 * lisp.h (lint_assume): New macro.
10322 * composite.c (composition_gstring_put_cache):
10323 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10325 * editfns.c, insdel.c:
10326 Omit unnecessary forward decls, to simplify future changes.
10328 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10330 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10332 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10333 Use much-faster test for byte-length change.
10334 Don't assume string byte-length fits in 'int'.
10335 Check that character arg fits in 'int'.
10336 (mapcar1): Declare byte as byte, for clarity.
10338 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10340 * fns.c (concat): Catch string overflow earlier.
10341 Do not rely on integer wraparound.
10343 * dispextern.h (struct it.overlay_strings_charpos)
10344 (struct it.selective): Now EMACS_INT, not int.
10345 * xdisp.c (forward_to_next_line_start)
10346 (back_to_previous_visible_line_start)
10347 (reseat_at_next_visible_line_start, next_element_from_buffer):
10348 Don't arbitrarily truncate the value of 'selective' to int.
10350 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10352 * composite.c: Don't truncate sizes to 'int'.
10353 (composition_gstring_p, composition_reseat_it)
10354 (composition_adjust_point): Use EMACS_INT, not int.
10355 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10356 not EMACS_UINT, for indexes.
10358 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10360 * buffer.c: Include <verify.h>.
10361 (struct sortvec.priority, struct sortstr.priority):
10362 Now EMACS_INT, not int.
10363 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10364 (struct sortstr.size, record_overlay_string)
10365 (struct sortstrlist.size, struct sortlist.used):
10366 Don't truncate size to int.
10367 (record_overlay_string): Check for size-calculation overflow.
10368 (init_buffer_once): Check at compile-time, not run-time.
10370 2011-06-22 Jim Meyering <meyering@redhat.com>
10372 Don't leak an XBM-image-sized buffer
10373 * image.c (xbm_load): Free the image buffer after using it.
10375 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10378 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10379 that Sun C diagnosed.
10380 * fns.c (secure_hash): Fix pointer signedness issue.
10381 * intervals.c (static_offset_intervals): New function.
10382 (offset_intervals): Use it.
10384 2011-06-21 Leo Liu <sdl.web@gmail.com>
10387 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10390 * fns.c (secure_hash): Rename from crypto_hash_function and change
10391 the first arg to accept symbols.
10392 (Fsecure_hash): New primitive.
10393 (syms_of_fns): New symbols.
10395 2011-06-20 Deniz Dogan <deniz@dogan.se>
10397 * process.c (Fset_process_buffer): Clarify return value in
10400 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10402 * dispnew.c (add_window_display_history): Use BVAR.
10404 * xdisp.c (debug_method_add): Use BVAR.
10405 (check_window_end, dump_glyph_matrix, dump_glyph)
10406 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10408 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10411 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10412 check till after the cache is created in init_frame_faces.
10414 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10416 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10418 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10420 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10421 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10422 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10424 Improve buffer-overflow checking (Bug#8873).
10425 * fileio.c (Finsert_file_contents):
10426 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10427 Remove the old (too-loose) buffer overflow checks.
10428 They weren't needed, since make_gap checks for buffer overflow.
10429 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10430 The old code merely checked for Emacs fixnum overflow, and relied
10431 on undefined (wraparound) behavior. The new code avoids undefined
10432 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10434 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10435 Tune. Don't use wider integers than needed. Don't use alloca.
10436 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10438 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10440 * insdel.c, lisp.h (buffer_overflow): New function.
10441 (insert_from_buffer_1, replace_range, replace_range_2):
10442 * insdel.c (make_gap_larger):
10443 * editfns.c (Finsert_char):
10444 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10446 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10448 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10450 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10452 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10453 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10455 * fileio.c: Don't assume EMACS_INT fits in off_t.
10456 (emacs_lseek): New static function.
10457 (Finsert_file_contents, Fwrite_region): Use it.
10458 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10460 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10462 * fns.c: Don't overflow int when computing a list length.
10463 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10464 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10465 truncation on 64-bit hosts. Check for QUIT every
10466 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10467 faster and is responsive enough.
10468 (Flength): Report an error instead of overflowing an integer.
10469 (Fsafe_length): Return a float if the value is not representable
10470 as a fixnum. This shouldn't happen except in contrived situations.
10471 (Fnthcdr, Fsort): Don't assume list length fits in int.
10472 (Fcopy_sequence): Don't assume vector length fits in int.
10474 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10475 (header_size, word_size): New constants.
10476 (allocate_vectorlike): Don't check size overflow here.
10477 (allocate_vector): Check it here instead, since this is the only
10478 caller of allocate_vectorlike that could cause overflow.
10479 Check that the new vector's length is representable as a fixnum.
10481 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10482 The previous code was bogus. For example, next_almost_prime (32)
10483 returned 39, which is undesirable as it is a multiple of 3; and
10484 next_almost_prime (24) returned 25, which is a multiple of 5 so
10485 why was the code bothering to check for multiples of 7?
10487 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10489 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10491 Variadic C functions now count arguments with ptrdiff_t.
10492 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10493 Back then I didn't know that the Emacs coding style prefers signed int.
10494 Also, in the meantime I found a few more instances where arguments
10495 were being counted with int, which may truncate counts on 64-bit
10496 machines, or EMACS_INT, which may be unnecessarily wide.
10497 * lisp.h (struct Lisp_Subr.function.aMANY)
10498 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10499 Arg counts are now ptrdiff_t, not size_t.
10500 All variadic functions and their callers changed accordingly.
10501 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10502 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10503 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10504 * callint.c (Fcall_interactively): Check arg count for overflow,
10505 to avoid potential buffer overrun. Use signed char, not 'int',
10506 for 'varies' array, so that we needn't bother to check its size
10507 calculation for overflow.
10508 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10509 * eval.c (apply_lambda):
10510 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10511 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10512 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10514 * callint.c (Fcall_interactively): Don't use index var as event count.
10516 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10517 * mem-limits.h (SIZE): Remove; no longer used.
10519 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10521 Remove unnecessary casts.
10522 * xterm.c (x_term_init):
10523 * xfns.c (x_set_border_pixel):
10524 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10525 These aren't needed now that we assume ANSI C.
10527 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10528 It's more likely to cause problems (due to unsigned overflow)
10531 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10533 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10535 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10537 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10539 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10541 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10543 GLYPH_CODE_FACE returns EMACS_INT, not int.
10544 * dispextern.h (merge_faces):
10545 * xfaces.c (merge_faces):
10546 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10547 Don't assume EMACS_INT fits in int.
10549 * character.h (CHAR_VALID_P): Remove unused parameter.
10550 * fontset.c, lisp.h, xdisp.c: All uses changed.
10552 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10554 * fns.c (concat): Minor tuning based on overflow analysis.
10555 This doesn't fix any bugs. Use int to hold character, instead
10556 of constantly refetching from Emacs object. Use XFASTINT, not
10557 XINT, for value known to be a character. Don't bother comparing
10558 a single byte to 0400, as it's always less.
10560 * floatfns.c (Fexpt):
10561 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10563 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10566 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10568 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10569 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10570 incorrectly succeed when S was a string, because 4294967386 was
10571 truncated before it was used.
10573 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10574 Otherwise, an out-of-range integer could cause undefined behavior
10577 * composite.c: Use int, not EMACS_INT, for characters.
10578 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10579 EMACS_INT, for values that are known to be in character range.
10580 This doesn't fix any bugs but is the usual style inside Emacs and
10581 may generate better code on 32-bit machines.
10583 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10584 This is for reasons similar to the recent CHAR_STRING fix.
10585 * charset.c (Fencode_char): Check that character arg is actually
10586 a character. Pass an int to ENCODE_CHAR.
10587 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10588 wider than 'int', as a compile-time check to prevent future regressions
10591 * character.c (char_string): Remove unnecessary casts.
10593 Make sure a 64-bit char is never passed to CHAR_STRING.
10594 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10595 by silently ignoring the top 32 bits, allowing some values
10596 that were far too large to be valid characters.
10597 * character.h: Include <verify.h>.
10598 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10599 arguments are no wider than unsigned, as a compile-time check
10600 to prevent future regressions in this area.
10602 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10603 (Fsubst_char_in_region):
10605 * xdisp.c (decode_mode_spec_coding):
10606 Adjust to CHAR_STRING's new requirement.
10607 * editfns.c (Finsert_char, Fsubst_char_in_region):
10608 * fns.c (concat): Check that character args are actually
10609 characters. Without this test, these functions did the wrong
10610 thing with wildly out-of-range values on 64-bit hosts.
10612 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10613 These casts should not be needed on 32-bit hosts, either.
10614 * keyboard.c (read_char):
10615 * lread.c (Fload): Remove casts to unsigned.
10617 * lisp.h (UNSIGNED_CMP): New macro.
10618 This fixes comparison bugs on 64-bit hosts.
10619 (ASCII_CHAR_P): Use it.
10620 * casefiddle.c (casify_object):
10621 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10622 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10623 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10624 * dispextern.h (FACE_FROM_ID):
10625 * keyboard.c (read_char): Use UNSIGNED_CMP.
10627 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10628 not to EMACS_INT, to avoid GCC warning.
10630 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10632 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10633 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10634 isn't needed on 32-bit machines.
10636 * buffer.c (Fgenerate_new_buffer_name):
10637 Use EMACS_INT for count, not int.
10638 (advance_to_char_boundary): Return EMACS_INT, not int.
10640 * data.c (Qcompiled_function): Now static.
10642 * window.c (window_body_lines): Now static.
10644 * image.c (gif_load): Rename local to avoid shadowing.
10646 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10647 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10648 * alloc.c (make_save_value): Integer argument is now of type
10649 ptrdiff_t, not int.
10650 (mark_object): Use ptrdiff_t, not int.
10651 * lisp.h (pD): New macro.
10652 * print.c (print_object): Use it.
10654 * alloc.c: Use EMACS_INT, not int, to count objects.
10655 (total_conses, total_markers, total_symbols, total_vector_size)
10656 (total_free_conses, total_free_markers, total_free_symbols)
10657 (total_free_floats, total_floats, total_free_intervals)
10658 (total_intervals, total_strings, total_free_strings):
10659 Now EMACS_INT, not int. All uses changed.
10660 (Fgarbage_collect): Compute overall total using a double, so that
10661 integer overflow is less likely to be a problem. Check for overflow
10662 when converting back to an integer.
10663 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10664 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10665 These were 'int' variables that could overflow on 64-bit hosts;
10666 they were never used, so remove them instead of repairing them.
10667 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10668 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10669 Previously, this ceilinged at INT_MAX, but that doesn't work on
10671 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10673 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10674 (allocate_vectorlike): Check for ptrdiff_t overflow.
10675 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10676 when a (possibly-narrower) signed value would do just as well.
10677 We prefer using signed arithmetic, to avoid comparison confusion.
10679 * alloc.c: Catch some string size overflows that we were missing.
10680 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10681 for convenience in STRING_BYTES_MAX.
10682 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10683 The definition here is exact; the one in lisp.h was approximate.
10684 (allocate_string_data): Check for string overflow. This catches
10685 some instances we weren't catching before. Also, it catches
10686 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10687 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10688 and ptrdiff_t and EMACS_INT are both 64 bits.
10690 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10691 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10692 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10694 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10696 * alloc.c (Fmake_string): Check for out-of-range init.
10698 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10700 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10702 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10704 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10705 xg_get_default_scrollbar_width.
10707 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10708 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10709 (style_changed_cb): Call update_theme_scrollbar_width and call
10710 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10711 all frames (Bug#8505).
10712 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10713 Call gtk_window_set_resizable if HAVE_GTK3.
10714 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10715 and height if HAVE_GTK3 (Bug#8505).
10716 (scroll_bar_width_for_theme): New variable.
10717 (update_theme_scrollbar_width): New function.
10718 (xg_get_default_scrollbar_width): Move code to
10719 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10720 (xg_initialize): Call update_theme_scrollbar_width.
10722 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10724 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10726 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10728 * frame.c (make_frame): Call other_buffer_safely instead of
10731 * window.c (temp_output_buffer_show): Call display_buffer with
10732 second argument Vtemp_buffer_show_specifiers and reset latter
10733 immediately after the call.
10734 (Vtemp_buffer_show_specifiers): New variable.
10735 (auto_window_vscroll_p, next_screen_context_lines)
10736 (Vscroll_preserve_screen_position): Remove leading asterisks from
10739 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10741 Fix minor problems found by GCC 4.6.0 static checking.
10742 * buffer.c (Qclone_number): Remove for now, as it's unused.
10743 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10744 (record_buffer): Remove unused local.
10745 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10746 (set_frame_buffer_list): Remove; unused.
10747 * frame.h (other_visible_frames): Remove decl.
10748 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.

10750 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10752 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10753 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10754 Define only if HAVE_GPM.
10755 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10756 (update_hints_inhibit): Remove; never set. All uses removed.
10757 * widgetprv.h (emacsFrameClassRec): Remove decl.
10758 * window.c (delete_deletable_window): Now returns void, since it
10759 wasn't returning anything.
10760 (compare_window_configurations): Remove unused locals.
10761 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10762 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10763 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10764 the same widths as pointers. This follows up on the 2011-05-06 patch.
10765 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10766 * xterm.h: Likewise.

10774 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10776 * image.c (gif_load): Add animation frame delay to the metadata.
10777 (syms_of_image): Use DEFSYM. New symbol `delay'.
10779 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10781 * window.c (delete_deletable_window): Re-add.
10782 (Fset_window_configuration): Rewrite to handle dead buffers and
10783 consequently deletable windows.
10784 (window_tree, Fwindow_tree): Remove. Supply functionality in
10786 (compare_window_configurations): Simplify code.
10788 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10790 * image.c (imagemagick_load_image): Fix type mismatch.
10791 (Fimagemagick_types): Likewise.
10793 * window.h (replace_buffer_in_windows): Declare.
10795 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10797 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10798 Qclone_number. Remove external declaration of Qdelete_window.
10799 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10801 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10802 Run Qbuffer_list_update_hook if allowed.
10803 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10804 buffer list implementation.
10805 (other_buffer_safely): New function.
10806 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10807 calls to replace_buffer_in_windows and
10808 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10810 (record_buffer): Inhibit quitting and rewrite using quittable
10811 functions. Run Qbuffer_list_update_hook if allowed.
10812 (Frecord_buffer, Funrecord_buffer): New functions.
10813 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10814 Move switch-to-buffer to window.el.
10815 (bury-buffer): Move to window.el.
10816 (Vbuffer_list_update_hook): New variable.
10818 * lisp.h (other_buffer_safely): Add prototype in buffer.c

10823 (replace_buffer_in_all_windows): Remove prototype.
10824 (replace_buffer_in_windows_safely): Add prototype.
10826 * window.c: Declare Qdelete_window static again. Move down
10827 declaration of select_count.
10828 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10829 (Fother_window): Move to window.el.
10830 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10831 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.

10834 (replace_buffer_in_windows): Implement by calling
10835 Qreplace_buffer_in_windows.
10836 (replace_buffer_in_all_windows): Remove with some functionality
10837 moved into replace_buffer_in_windows_safely.
10838 (replace_buffer_in_windows_safely): New function.
10839 (select_window_norecord, select_frame_norecord): Move in front
10840 of run_window_configuration_change_hook. Remove now obsolete
10842 (Fset_window_buffer): Rewrite doc-string.

10844 (keys_of_window): Move binding for other-window to window.el.
10846 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10848 * dispextern.h (struct image): Replace data member, whose int_val
10849 and ptr_val fields were not used by anything, with a single
10852 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
10853 (gif_clear_image, gif_load, imagemagick_load_image)

11300 value of a `display' property is a "replacing spec".
11301 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11302 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11332 * gnutls.c: Use Emacs's memory allocators.
11333 Without this change, the gnutls library would invoke malloc etc.
11334 directly, which causes problems on non-SYNC_INPUT hosts, and which
11335 runs afoul of improving memory_full behavior. (Bug#8761)
11336 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11337 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11338 xfree instead of the default malloc, realloc, free.
11339 (Fgnutls_boot): No need to check for memory allocation failure,
11340 since xmalloc does that for us.

11360 * lisp.h (struct Lisp_Hash_Table):
11361 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11362 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11363 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11364 * alloc.c (allocate_vectorlike):
11365 Check for overflow in vector size calculations.
11366 * ccl.c (ccl_driver):
11367 Check for overflow when converting EMACS_INT to int.
11368 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11369 need to be updated by these changes.
11370 * fns.c (make_hash_table, maybe_resize_hash_table):
11371 Check for integer overflow with large hash tables.
11372 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11373 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11374 (SXHASH_REDUCE): New macro.
11375 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11376 Use it instead of discarding useful hash info with large hash values.
11377 (sxhash_float): New function.
11378 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11379 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11380 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11381 Rewrite to use FIXNUM_BITS, as this simplifies things.
11382 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11383 Adjust signatures to match updated version of code.
11384 (consing_since_gc): Now EMACS_INT, since a single hash table can
11385 use more than INT_MAX bytes.
11387 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11389 Make it possible to build with GCC-4.6+ -O2 -flto.

11400 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11401 Update dependencies.
11403 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11405 * data.c (init_data): Remove code for UTS, this system is not
11408 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11410 Don't force ./temacs to start in terminal mode.
11412 * frame.c (make_initial_frame): Initialize faces in all cases, not
11413 only when CANNOT_DUMP is defined.
11414 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11416 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11418 * dispnew.c (add_window_display_history): Use const for the string
11419 pointer. Remove declaration, not needed.
11421 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11423 Use 'inline', not 'INLINE'.
11424 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11425 * alloc.c, fontset.c (INLINE): Remove.
11426 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11427 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11428 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11429 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11430 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11432 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11434 Make it possible to run ./temacs.
11436 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11437 syms_of_callproc does the same thing. Remove test for
11438 "initialized", do it in the caller.
11439 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11441 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11443 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11444 (read_minibuf): Use get_minibuffer.
11445 (syms_of_minibuf): Use DEFSYM.
11446 (Qmetadata): New var.
11447 * data.c (Qbuffer): Don't make it static.
11448 (syms_of_data): Use DEFSYM.
11450 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11452 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11453 (CCL_CODE_MIN): New macro.
11455 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11457 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11459 * eval.c (Qdebug): Now static.
11460 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11461 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11462 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11464 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11466 * image.c: Various fixes to ImageMagick code comments.
11467 (Fimagemagick_types): Doc fix.
11469 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11471 Minor fixes prompted by GCC 4.6.0 warnings.
11473 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11475 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11476 (x_clipboard_manager_save_all): Move extern decl to ...
11477 * xterm.h: ... here, so that it can be checked for consistency.
11479 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11481 * xselect.c (x_clipboard_manager_save_frame)
11482 (x_clipboard_manager_save_all): New functions.
11483 (Fx_clipboard_manager_save): Lisp function deleted.
11485 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11486 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11488 * xterm.h: Update prototype.
11490 2011-05-28 William Xu <william.xwl@gmail.com>
11492 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11493 exiting (Bug#8239).
11495 2011-05-28 Jim Meyering <meyering@redhat.com>
11497 Avoid a sign-extension bug in crypto_hash_function.
11498 * fns.c (to_uchar): Define.
11499 (crypto_hash_function): Use it to convert some newly-signed
11500 variables to unsigned, to avoid sign-extension bugs. For example,
11501 without this change, (md5 "truc") would evaluate to
11502 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11503 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11504 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11506 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11508 Integer overflow fixes.
11510 * dbusbind.c: Serial number integer overflow fixes.
11511 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11512 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11513 to hold a serial number that is too large for a fixnum.
11514 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11515 Check for serial numbers out of range. Decode any serial number
11516 that was so large that it became a float. (Bug#8722)
11518 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11519 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11520 Use XFASTINT rather than XUINT when numbers are nonnegative.
11521 (xd_append_arg, Fdbus_method_return_internal):
11522 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11523 arguments, check that Lisp number is nonnegative, rather than
11524 silently wrapping negative numbers around. (Bug#8722)
11525 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11528 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11530 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11532 ccl: Add integer overflow checks.
11533 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11534 (IN_INT_RANGE): New macros.
11535 (ccl_driver): Use them to check for integer overflow when
11536 decoding a CCL program. Many of the new checks are whether XINT (x)
11537 fits in int; it doesn't always, on 64-bit hosts. The new version
11538 doesn't catch all possible integer overflows, but it's an
11539 improvement. (Bug#8719)
11541 * alloc.c (make_event_array): Use XINT, not XUINT.
11542 There's no need for unsigned here.
11544 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11545 This follows up to the 2011-05-06 change that substituted uintptr_t
11546 for EMACS_INT. This case wasn't caught back then.
11548 Rework Fformat to avoid integer overflow issues.
11549 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11550 now (part of C89). Include <verify.h>.
11551 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11552 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11553 (Fformat): Avoid the prepass trying to compute sizes; it was only
11554 approximate and thus did not catch overflow reliably. Instead, walk
11555 through the format just once, formatting and computing sizes as we go,
11556 checking for integer overflow at every step, and allocating a larger
11557 buffer as needed. Keep track separately whether the format is
11558 multibyte. Keep only the most-recently calculated precision, rather
11559 than them all. Record whether each argument has been converted to
11560 string. Use EMACS_INT, not int, for byte and char and arg counts.
11561 Support field widths and precisions larger than INT_MAX. Avoid
11562 sprintf's undefined behavior with conversion specifications such as %#d
11563 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11564 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11565 formatting out-of-range floating point numbers with int
11566 formats. (Bug#8668)
11568 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11570 * data.c: Avoid integer truncation in expressions involving floats.
11571 * data.c: Include <intprops.h>.
11572 (arith_driver): When there's an integer overflow in an expression
11573 involving floating point, convert the integers to floating point
11574 so that the resulting value does not suffer from catastrophic
11575 integer truncation. For example, on a 64-bit host (* 4
11576 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11577 Do not rely on undefined behavior after integer overflow.
11579 merge count_size_as_multibyte, parse_str_to_multibyte
11580 * character.c, character.h (count_size_as_multibyte):
11581 Rename from parse_str_to_multibyte; all uses changed.
11582 Check for integer overflow.
11583 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11584 since it's now a duplicate of the other. This is more of
11585 a character than a buffer op, so better that it's in character.c.
11586 * fns.c, print.c: Adjust to above changes.
11588 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11590 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11592 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11594 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11595 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11596 (x_clipboard_manager_save): Now static.
11597 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11599 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11600 (crypto_hash_function): Now static.
11601 Fix pointer signedness problems. Avoid unnecessary initializations.
11603 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11605 * termhooks.h (Vselection_alist): Make it terminal-local.
11607 * terminal.c (create_terminal): Initialize it.
11609 * xselect.c: Support for clipboard managers.
11610 (Vselection_alist): Move to termhooks.h as terminal-local var.
11611 (LOCAL_SELECTION): New macro.
11612 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11613 (symbol_to_x_atom): Remove gratuitous arg.
11614 (x_handle_selection_request, lisp_data_to_selection_data)
11615 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11616 (x_own_selection, x_get_local_selection, x_convert_selection):
11617 New arg, specifying work frame. Use terminal-local Vselection_alist.
11618 (some_frame_on_display): Delete unused function.
11619 (Fx_own_selection_internal, Fx_get_selection_internal)
11620 (Fx_disown_selection_internal, Fx_selection_owner_p)
11621 (Fx_selection_exists_p): New optional frame arg.
11622 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11623 (x_handle_selection_clear): Don't treat other terminals with the
11624 same keyboard specially. Use the terminal-local Vselection_alist.
11625 (x_clear_frame_selections): Use Frun_hook_with_args.
11627 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11629 * xterm.h: Add support for those atoms.
11631 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11633 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11634 (converted_selections, conversion_fail_tag): New global variables.
11635 (x_selection_request_lisp_error): Free the above.
11636 (x_get_local_selection): Remove unnecessary code.
11637 (x_reply_selection_request): Args changed; handle arbitrary array
11638 of converted selections stored in converted_selections.
11639 Separate the XChangeProperty and SelectionNotify steps.
11640 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11641 (x_convert_selection): New function.
11642 (x_handle_selection_event): Simplify.
11643 (x_get_foreign_selection): Don't ignore incoming requests while
11644 waiting for an answer; this will fail when we implement
11645 SAVE_TARGETS, and seems unnecessary anyway.
11646 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11647 (Vx_sent_selection_functions): Doc fix.
11649 2011-05-26 Leo Liu <sdl.web@gmail.com>
11651 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11653 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11655 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11657 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11658 for fringe update if it has periodic bitmap.
11659 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11660 and fringe_bitmap_periodic_p.
11662 * fringe.c (get_fringe_bitmap_data): New function.
11663 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11664 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11665 row. Mark glyph row for fringe update if periodicity changed.
11667 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11668 for fringe update unless it has periodic bitmap.
11670 2011-05-25 Kenichi Handa <handa@m17n.org>
11672 * xdisp.c (get_next_display_element): Set correct it->face_id for
11673 a static composition.

11684 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11686 * gnutls.c: Remove unused macros.
11687 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11688 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11689 Remove macros that are defined and never used.
11690 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11692 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11694 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11695 (Fx_get_selection_internal): Minor cleanup.
11696 (Fx_own_selection_internal): Rename arguments for consistency with
11699 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

11714 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11715 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11716 and add some more files.

11720 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11721 report_file_error introduced by the change from 2011-05-07.
11723 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11725 * systime.h (Time): Define only if emacs is defined.
11726 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11727 where the include path doesn't have X11/X.h by default. See
11728 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11730 2011-05-20 Kenichi Handa <handa@m17n.org>
11732 * composite.c (find_automatic_composition): Fix previous change.
11734 2011-05-20 Glenn Morris <rgm@gnu.org>
11736 * lisp.mk: New file, split from Makefile.in.
11737 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11738 (shortlisp): Remove.
11739 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11741 2011-05-19 Glenn Morris <rgm@gnu.org>
11743 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11744 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11745 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11746 (lisp): Set the order to that of loadup.el.
11747 (shortlisp): Make it a copy of $lisp.
11748 (SOME_MACHINE_LISP): Remove.
11749 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11750 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11752 2011-05-18 Kenichi Handa <handa@m17n.org>
11754 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11755 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11756 (find_automatic_composition): Mostly rewrite for efficiency.
11758 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11760 * makefile.w32-in: Update dependencies.
11762 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11764 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11765 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11767 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11769 Fix some integer overflow issues, such as string length overflow.
11771 * insdel.c (count_size_as_multibyte): Check for string overflow.
11773 * character.c (lisp_string_width): Check for string overflow.
11774 Use EMACS_INT, not int, for string indexes and lengths; in
11775 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11776 the resulting string length overflows an EMACS_INT; instead,
11777 report a string overflow if no precision given. When checking for
11778 precision exhaustion, use a check that cannot possibly have
11779 integer overflow. (Bug#8675)
11780 * character.h (lisp_string_width): Adjust to new signature.
11782 * alloc.c (string_overflow): New function.
11783 (Fmake_string): Use it. This doesn't change behavior, but saves
11784 a few bytes and will simplify future changes.
11785 * character.c (string_escape_byte8): Likewise.
11786 * lisp.h (string_overflow): New decl.
11788 Fixups, following up to the user-interface timestamp change.
11789 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11790 for UI timestamps, instead of unsigned long.
11791 * msdos.c (mouse_get_pos): Likewise.
11792 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11793 * w32gui.h (Time): Define by including "systime.h" rather than by
11794 declaring it ourselves. (Bug#8664)
11796 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11797 * image.c (clear_image_cache): Likewise.
11799 * term.c (term_mouse_position): Don't assume time_t wraparound.
11801 Be more systematic about user-interface timestamps.
11802 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11803 and sometimes 'EMACS_UINT', to represent these timestamps.
11804 This change causes it to use 'Time' uniformly, as that's what X uses.
11805 This makes the code easier to follow, and makes it easier to catch
11806 integer overflow bugs such as Bug#8664.
11807 * frame.c (Fmouse_position, Fmouse_pixel_position):
11808 Use Time, not unsigned long, for user-interface timestamps.
11809 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11810 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11811 * keyboard.h (last_event_timestamp): Likewise.
11812 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11813 * menu.h (xmenu_show): Likewise.
11814 * term.c (term_mouse_position): Likewise.
11815 * termhooks.h (struct input_event.timestamp): Likewise.
11816 (struct terminal.mouse_position_hook): Likewise.
11817 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11818 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11819 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11820 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11821 what it was before.
11822 * menu.h, termhooks.h: Include "systime.h", for Time.
11824 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11825 Don't assume that the difference between two unsigned long values
11826 can fit into an integer. At this point, we know button_down_time
11827 <= event->timestamp, so the difference must be nonnegative, so
11828 there's no need to cast the result if double-click-time is
11829 nonnegative, as it should be; check that it's nonnegative, just in
11830 case. This bug is triggered when events are more than 2**31 ms
11831 apart (about 25 days). (Bug#8664)
11833 * xselect.c (last_event_timestamp): Remove duplicate decl.
11834 (x_own_selection): Remove needless cast to unsigned long.
11836 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11837 that always fit in int. Use a sentinel instead of a counter, to
11838 avoid a temp and to allay GCC's concerns about possible int overflow.
11839 * frame.h (struct frame): Use int for menu_bar_items_used
11840 instead of EMACS_INT, since it always fits in int.
11842 * menu.c (grow_menu_items): Check for int overflow.
11844 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11846 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11847 Before, the code was not consistent. These values cannot exceed
11848 2**31 - 1 so there's no need to make them unsigned.
11849 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11850 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11851 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11853 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11855 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11856 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11857 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11858 presumably because the widths might not match.
11860 * window.c (size_window): Avoid needless test at loop start.
11862 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11864 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11866 2011-05-12 Drew Adams <drew.adams@oracle.com>
11868 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11870 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11872 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11873 `width' to `bar_area_x' and `bar_area_width', respectively.
11874 (x_scroll_run): Take account of fringe background extension.
11876 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11877 Rename local vars `left' and `width' to `bar_area_x' and
11878 `bar_area_width', respectively.
11879 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11880 background extension.
11882 2011-05-10 Jim Meyering <meyering@redhat.com>
11884 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11886 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11888 * image.c (Finit_image_library): Return t for built-in image types,
11889 like pbm and xbm. (Bug#8640)
11891 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11893 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11895 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11897 * w32console.c (Fset_screen_color): Doc fix.
11898 (Fget_screen_color): New function.
11899 (syms_of_ntterm): Defsubr it.
11901 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11902 unlink the temporary file if Fcall_process didn't create it in the
11904 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11905 child process will be redirected to a file specified with `:file'.
11906 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11907 cue to call_process_cleanup not to close that handle.
11909 2011-05-07 Ben Key <bkey76@gmail.com>
11911 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11912 one of two shell specific rules, either bootstrap-temacs-CMD or
11913 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11914 to the previous implementation of the bootstrap-temacs rule.
11915 The bootstrap-temacs-CMD rule is similar to the previous
11916 implementation of the bootstrap-temacs rule except that it
11917 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11920 These changes, along with some changes to nt/configure.bat,
11921 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11922 earlier fix to add support for --cflags and --ldflags options
11923 that include quotes so that it works whether make uses cmd or
11926 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11928 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11929 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11931 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11932 a string. Handle both cases.
11933 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11934 (Fdbus_register_method): Use Qinvalid_function.
11936 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11938 * makefile.w32-in: Update dependencies.
11939 (LISP_H): Add inttypes.h and stdin.h.
11940 (PROCESS_H): Add unistd.h.
11942 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11944 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11945 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11947 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11949 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11951 * term.c (vfatal): Remove stray call to va_end.
11952 It's not needed and the C Standard doesn't allow it here anyway.
11954 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11955 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11957 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11960 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11962 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11964 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11966 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11968 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11970 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11971 * charset.c (Fdefine_charset_internal): Don't initialize
11972 charset.code_space[15]. The value was garbage, on hosts with
11973 32-bit int (Bug#8600).
11975 * lread.c (read_integer): Be more consistent with string-to-number.
11976 Use string_to_number to do the actual conversion; this avoids
11977 rounding errors and fixes some other screwups. Without this fix,
11978 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11979 (digit_to_number): Move earlier, for benefit of read_integer.
11980 Return -1 if the digit is out of range for the base, -2 if it is
11981 not a digit in any supported base. (Bug#8602)
11983 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11985 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11986 to match comment at start of function. This also removes a
11987 GCC warning about overflow in a 32+64-bit port.
11989 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11991 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11992 Reported by Stefan Monnier in
11993 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11994 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11995 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11997 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11998 (EMACS_UINTPTR): Likewise, with uintptr_t.
12000 * lisp.h: Prefer 64-bit EMACS_INT if available.
12001 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12002 on 32-bit hosts that have 64-bit int, so that they can access
12004 However, temporarily disable this change unless the temporary
12005 symbol WIDE_EMACS_INT is defined.
12007 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12009 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12010 This removes an assumption that EMACS_INT and long are the same
12011 width as pointers. The assumption is true for Emacs porting targets
12012 now, but we want to make other targets possible.
12013 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12014 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12015 In the rest of the code, change types of integers that hold casted
12016 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12017 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12018 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12019 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12020 No need to cast type when ORing.
12021 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12022 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12023 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12024 assume EMACS_INT is the same width as char *.
12025 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12026 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12027 Remove no-longer-needed casts.
12028 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12029 (xg_tool_bar_help_callback, xg_make_tool_item):
12030 Use EMACS_INTPTR to hold an integer
12031 that will be cast to void *; this can avoid a GCC warning
12032 if EMACS_INT is not the same width as void *.
12033 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12034 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12035 (current_message_1, set_message_1):
12036 Use a local to convert to proper width without a cast.
12037 * xmenu.c (dialog_selection_callback): Likewise.
12039 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12040 Also, don't assume VALBITS / RAND_BITS is less than 5,
12041 and don't rely on undefined behavior when shifting a 1 left into
12043 * lisp.h (get_random): Change signature to match.
12045 * lread.c (hash_string): Use size_t, not int, for hash computation.
12046 Normally we prefer signed values; but hashing is special, because
12047 it's better to use unsigned division on hash table sizes so that
12048 the remainder is nonnegative. Also, size_t is the natural width
12049 for hashing into memory. The previous code used 'int', which doesn't
12050 retain enough info to hash well into very large tables.
12051 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12053 * dbusbind.c: Don't possibly lose pointer info when converting.
12054 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12055 Use XPNTR rather than XHASH, so that the high-order bits of
12056 the pointer aren't lost when converting through void *.
12058 * eval.c (Fautoload): Don't double-shift a pointer.
12060 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12062 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12064 * gnutls.c (DEF_GNUTLS_FN):
12065 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12067 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12069 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12072 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12074 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12075 New version that can reserve upto 2GB of heap space.
12077 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12079 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12081 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12083 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12084 `gnutls_certificate_set_x509_key_file'.
12086 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12088 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12089 Update dependencies.
12091 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12093 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12094 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12095 Remove unused parameter `fildes'.
12096 * process.c (read_process_output, send_process): Don't pass it.
12098 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12100 Fix previous change: the library cache is defined in w32.c.
12101 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12102 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12104 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12106 Implement dynamic loading of GnuTLS on Windows.
12108 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12109 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12110 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12113 * gnutls.c (Qgnutls_dll): Define.
12114 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12115 (gnutls_*): Declare function pointers.
12116 (init_gnutls_functions): New function to initialize function pointers.
12117 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12118 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12119 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12120 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12121 (emacs_gnutls_write, emacs_gnutls_read)
12122 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12123 (Fgnutls_available_p): New function.
12124 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12125 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12126 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12128 * image.c: Include w32.h.
12129 (Vimage_type_cache): Delete.
12130 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12131 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12132 (w32_delayed_load): Move to w32.c.
12134 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12136 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12137 (w32_delayed_load): Move from image.c. When loading a library, record
12138 its filename in the :loaded-from property of the library id.
12139 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12140 Initialize and staticpro them.
12141 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12143 * process.c: Include lisp.h before w32.h, not after.
12144 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12145 instead of gnutls_record_check_pending.
12147 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12149 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12151 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12152 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12155 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12157 * xterm.c (x_set_frame_alpha): Do not set property on anything
12158 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12160 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12162 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12164 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12166 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12167 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
12168 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

12173 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12174 (Qgnutls_bootprop_callbacks_verify): Make static.
12176 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12178 * callproc.c: Indentation fixup.
12180 * sysdep.c (wait_for_termination_1): Make static.
12181 (wait_for_termination, interruptible_wait_for_termination):
12182 Move after wait_for_termination_1.
12184 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12186 * sysdep.c (interruptible_wait_for_termination): New function
12187 which is like wait_for_termination, but allows keyboard
12190 * callproc.c (Fcall_process): Add (:file "file") as an option for
12192 (Fcall_process_region): Ditto.
12194 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12196 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12197 rather than `XVECTOR (FOO)->size'.
12199 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12200 inttypes.h, as a gnulib replacement is used if it not available in
12203 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12205 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12206 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12207 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12209 * coding.c (coding_alloc_by_realloc): Error out if destination
12210 will grow beyond MOST_POSITIVE_FIXNUM.
12211 (decode_coding_emacs_mule): Abort if there isn't enough place in
12212 charbuf for the composition carryover bytes. Reserve an extra
12213 space for up to 2 characters produced in a loop.
12214 (decode_coding_iso_2022): Abort if there isn't enough place in
12215 charbuf for the composition carryover bytes.
12217 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12219 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12220 aborting when %lld or %lll format is passed.
12221 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12222 %llo or %llx format is passed. (Bug#8545)
12224 * window.c (window_scroll_line_based): Use a marker instead of
12225 simple variables to record original value of point. (Bug#7952)
12227 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12228 produced by %s or %c overflows available buffer space. (Bug#8545)
12230 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12232 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12233 (SIZE_MAX): Move defn after all includes, as they might #define it.
12235 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12237 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12239 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12241 * keyboard.c (Qdelayed_warnings_hook): Define.
12242 (command_loop_1): Run `delayed-warnings-hook'
12243 if Vdelayed_warnings_list is non-nil.
12244 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12245 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12247 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12249 * doprnt.c (doprnt): Don't return value smaller than the buffer
12250 size if the message was truncated. (Bug#8545).
12252 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12254 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12255 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12257 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12259 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12261 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12263 * makefile.w32-in: Update dependencies.
12265 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12267 Improve `doprnt' and its usage. (Bug#8545)
12268 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12269 `format_end'. Remove support for %l as a conversion specifier.
12270 Don't use xrealloc. Improve diagnostics when the %l size modifier
12271 is used. Update the commentary.
12273 * eval.c (verror): Simplify calculation of size_t.
12275 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12278 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12280 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12283 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12285 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12286 This makes this file independent of the recent pseudovector change.
12288 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12290 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12292 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12293 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12294 Remove unused local.
12295 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12297 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12298 GCC 4.6.0 optimizes based on type-based alias analysis.
12299 For example, if b is of type struct buffer * and v of type struct
12300 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12301 != &v->size, and therefore "v->size = 1; b->size = 2; return
12302 v->size;" must therefore return 1. This assumption is incorrect
12303 for Emacs, since it type-puns struct Lisp_Vector * with many other
12304 types. To fix this problem, this patch adds a new type struct
12305 vectorlike_header that documents the constraints on layout of vectors
12306 and pseudovectors, and helps optimizing compilers not get fooled
12307 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12308 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12309 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12311 (XSETPVECTYPE): Rewrite in terms of new macro.
12312 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12313 This is a bit clearer, and further avoids the possibility of
12314 undesirable aliasing.
12315 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12316 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12317 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12318 since Lisp_Subr is a special case (no "next" field).
12319 (ASIZE): Now uses header.size rather than size.
12320 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12321 to avoid the hassle of writing XVECTOR (foo)->header.size.
12322 (struct vectorlike_header): New type.
12323 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12324 object, to help avoid aliasing.
12325 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12326 (SUBRP): Likewise, since Lisp_Subr is a special case.
12327 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12328 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12329 (struct Lisp_Hash_Table): Combine first two members into a single
12330 struct vectorlike_header member. All uses of "size" and "next" members
12331 changed to be "header.size" and "header.next".
12332 * buffer.h (struct buffer): Likewise.
12333 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12334 * frame.h (struct frame): Likewise.
12335 * process.h (struct Lisp_Process): Likewise.
12336 * termhooks.h (struct terminal): Likewise.
12337 * window.c (struct save_window_data, struct saved_window): Likewise.
12338 * window.h (struct window): Likewise.
12339 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12340 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12341 * buffer.c (init_buffer_once): Likewise.
12342 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12344 * process.c (Fformat_network_address): Use local var for size,
12347 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12349 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12350 * data.c (atof): Remove decl; no longer used or needed.
12351 (digit_to_number): Move to lread.c.
12352 (Fstring_to_number): Use new string_to_number function, to be
12353 consistent with how the Lisp reader treats infinities and NaNs.
12354 Do not assume that floating-point numbers represent EMACS_INT
12355 without losing information; this is not true on most 64-bit hosts.
12356 Avoid double-rounding errors, by insisting on integers when
12357 parsing non-base-10 numbers, as the documentation specifies.
12358 * lisp.h (string_to_number): New decl, replacing ...
12359 (isfloat_string): Remove.
12360 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12361 (read1): Do not accept +. and -. as integers; this
12362 appears to have been a coding error. Similarly, do not accept
12363 strings like +-1e0 as floating point numbers. Do not report
12364 overflow for integer overflows unless the base is not 10 which
12365 means we have no simple and reliable way to continue.
12366 Break out the floating-point parsing into a new
12367 function string_to_number, so that Fstring_to_number parses
12368 floating point numbers consistently with the Lisp reader.
12369 (digit_to_number): Move here from data.c. Make it static inline.
12370 (E_CHAR, EXP_INT): Remove, replacing with ...
12371 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12372 (string_to_number): New function, replacing isfloat_string.
12373 This function checks for valid syntax and produces the resulting
12374 Lisp float number too. Rework it so that string-to-number
12375 no longer mishandles examples like "1.0e+". Use strtoumax,
12376 so that overflow for non-base-10 numbers is reported only when
12377 there's no portable and simple way to convert to floating point.
12379 * textprop.c (set_text_properties_1): Rewrite for clarity,
12380 and to avoid GCC warning about integer overflow.
12382 * intervals.h (struct interval): Use EMACS_INT for members
12383 where EMACS_UINT might cause problems. See
12384 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12385 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12386 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12388 (offset_intervals): Tell GCC not to worry about length overflow
12389 when negating a negative length.
12391 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12392 (overrun_check_free): Likewise.
12394 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12395 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12398 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12399 (gnutls_make_error): Rename local to avoid shadowing.
12400 (gnutls_emacs_global_deinit): ifdef out; not used.
12401 (Fgnutls_boot): Use const for pointer to readonly storage.
12402 Comment out unused local. Fix pointer signedness problems.
12404 * lread.c (openp): Don't stuff size_t into an 'int'.
12405 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12406 about possible signed overflow.
12408 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12409 (GDK_KEY_g): Don't define if already defined.
12410 (xg_prepare_tooltip): Avoid pointer signedness problem.
12411 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12413 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12414 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12416 * xfns.c (Fx_window_property): Simplify a bit,
12417 to make a bit faster and to avoid GCC 4.6.0 warning.
12418 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12420 * fns.c (internal_equal): Don't assume size_t fits in int.
12422 * alloc.c (compact_small_strings): Tighten assertion a little.
12424 Replace pEd with more-general pI, and fix some printf arg casts.
12425 * lisp.h (pI): New macro, generalizing old pEd macro to other
12426 conversion specifiers. For example, use "...%"pI"d..." rather
12427 than "...%"pEd"...".
12428 (pEd): Remove. All uses replaced with similar uses of pI.
12429 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12430 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12431 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12432 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12433 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12434 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12435 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12437 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12438 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12439 * print.c (safe_debug_print, print_object): Likewise.
12440 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12442 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12443 avoiding the 0 flag, which is not portable.
12444 * process.c (Fmake_network_process): Use pI to avoid cast.
12445 * region-cache.c (pp_cache): Likewise.
12446 * xdisp.c (decode_mode_spec): Likewise.
12447 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12448 behavior on 64-bit hosts with printf arg.
12449 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12450 (x_stop_queuing_selection_requests): Likewise.
12451 (x_get_window_property): Don't truncate byte count to an 'int'
12454 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12455 here, since it parses constructs like leading '-' and spaces,
12456 which are not wanted; and it overflows with large numbers.
12457 Instead, simply match F[0-9]+, which is what is wanted anyway.
12459 * alloc.c: Remove unportable assumptions about struct layout.
12460 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12461 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12462 (allocate_vectorlike, make_pure_vector): Use the new macros,
12463 plus offsetof, to remove unportable assumptions about struct layout.
12464 These assumptions hold on all porting targets that I know of, but
12465 they are not guaranteed, they're easy to remove, and removing them
12466 makes further changes easier.
12468 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12469 This doesn't fix a bug but makes the code clearer.
12470 (string_overrun_cookie): Now const. Use initializers that
12471 don't formally overflow signed char, to avoid warnings.
12472 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12473 can cause Emacs to crash when string overrun checking is enabled.
12474 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12475 multiple of sizeof (EMACS_INT); it need not be, if
12476 alignof(EMACS_INT) < sizeof (EMACS_INT).
12477 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12479 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12481 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12483 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12485 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12486 supposed to be handshaking. (Bug#8556)
12487 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12489 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12491 * lisp.h (Qdebug): List symbol.
12492 * eval.c (Qdebug): Restore global linkage.
12493 * keyboard.c (debug-on-event): New variable.
12494 (handle_user_signal): Break into debugger when debug-on-event
12495 matches the current signal symbol.
12497 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12499 * alloc.c (check_sblock, check_string_bytes)
12500 (check_string_free_list): Convert to standard C.
12502 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12504 * w32.c (emacs_gnutls_push): Fix typo.
12506 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12508 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12509 "cast to pointer from integer of different size".
12511 Improve doprnt and its use in verror. (Bug#8545)
12512 * doprnt.c (doprnt): Document the set of format control sequences
12513 supported by the function. Use SAFE_ALLOCA instead of always
12516 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12517 is one byte too soon. Don't use xrealloc; instead xfree and
12520 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12522 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12525 * gnutls.c: Renamed global_initialized to
12526 gnutls_global_initialized. Added internals for the
12527 :verify-hostname-error, :verify-error, and :verify-flags
12528 parameters of `gnutls-boot' and documented those parameters in the
12529 docstring. Start callback support.
12530 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12531 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12532 on error. Return error code.
12533 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12534 (emacs_gnutls_read): Likewise.
12535 (Fgnutls_boot): Return handshake error code.
12536 (emacs_gnutls_handle_error): New function.
12537 (wsaerror_to_errno): Likewise.

12569 <menu_help_message, prev_menu_help_message>: Constify.
12570 (IT_menu_make_room): menu->help_text is now `const char **';
12573 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
12574 to changes in oldXMenu/XMenu.h from 2011-04-16.
12575 (struct XMenu): Declare `help_text' `const char **'.

12592 changes in globals.h immediately force recompilation.
12593 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12594 $(CURDIR)/s/ms-w32.h.
12595 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

12598 (syms_of_character): Don't defsubr it.
12599 <char-direction-table>: Deleted.
12601 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12603 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12604 * doprnt.c: Include limits.h.
12605 (SIZE_MAX): New macro.
12606 (doprnt): Return a size_t value. 2nd arg is now size_t.
12607 Many local variables are now size_t instead of int or unsigned.
12608 Improve overflow protection. Support `l' modifier for integer
12609 conversions. Support %l conversion. Don't assume an EMACS_INT
12610 argument for integer conversions and for %c.
12612 * lisp.h (doprnt): Restore prototype.
12614 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12615 $(SRC)/character.h.
12617 * Makefile.in (base_obj): Add back doprnt.o.
12619 * deps.mk (doprnt.o): Add back prerequisites.
12620 (callint.o): Depend on character.h.
12622 * eval.c (internal_lisp_condition_case): Include the handler
12623 representation in the error message.
12624 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12625 when breaking from the loop.
12627 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12629 * callint.c (Fcall_interactively): When displaying error message
12630 about invalid control letter, pass the character's codepoint, not
12631 a pointer to its multibyte form. Improve display of the character
12632 in octal and display also its hex code.
12634 * character.c (char_string): Use %x to display the (unsigned)
12635 codepoint of an invalid character, to avoid displaying a bogus
12638 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12639 `error', not SYMBOL_NAME itself.
12641 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12642 character arguments to `error'.
12644 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12645 to `error' in error message about FINAL_CHAR argument. Make sure
12646 FINAL_CHAR is a character, and use %c when it is passed as
12647 argument to `error'.

12837 ns_descriptor_to_entity that were caused by using free to
12838 deallocate memory blocks that were allocated by xmalloc (via
12839 xstrdup). This caused Emacs to crash when compiled with

12860 * process.c (send_process): Adjust to the new signatures of
12861 emacs_write and emacs_gnutls_write. Do not attempt to store

13108 * font.h (ftxfont_driver): Likewise.
13110 * xfns.c: Make symbols static if they're not exported.

13191 * lisp.h: Remove these decls.
13193 * buffer.c (buffer_count): Remove unused var.
13195 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
13196 so that it's not optimized away.
13197 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13198 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13199 exported only to the debugger.
13201 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
13202 * atimer.h (run_all_atimers): Remove; not exported.
13204 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13205 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13206 was inaccessible from Lisp.
13207 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13208 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13210 alloc.c: Import and export fewer symbols, and remove unused items.
13211 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13213 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13214 it's not optimized away by whole-program optimization.

13226 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13227 (mark_backtrace): Define only if BYTE_MARK_STACK.
13228 * xdisp.c (message_enable_multibyte): Now static.
13230 Declare Lisp_Object Q* variables to be 'static' if not exported.
13231 This makes it easier for human readers (and static analyzers)
13232 to see whether these variables are used from other modules.
13233 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13234 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

13243 Remove decls of unexported vars.
13244 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13246 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13248 Make Emacs functions such as Fatom 'static' by default.
13249 This makes it easier for human readers (and static analyzers)
13250 to see whether these functions can be called from other modules.
13251 DEFUN now defines a static function. To make the function external
13252 so that it can be used in other C modules, use the new macro DEFUE.
13253 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13254 (Finit_image_library):
13255 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13256 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13257 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13258 Remove decls, since these functions are now static.
13259 (Funintern, Fget_internal_run_time): New decls, since these functions
13260 were already external.
13262 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

13269 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13270 Mark functions with DEFUE instead of DEFUN,
13271 if they are used in other modules.
13272 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13273 decls for now-static functions.
13274 * buffer.h (Fdelete_overlay): Remove decl.
13275 * callproc.c (Fgetenv_internal): Mark as internal.
13276 * composite.c (Fremove_list_of_text_properties): Remove decl.

13284 * image.c (Finit_image_library): New forward static decl.
13285 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13286 * intervals.h (Fprevious_property_change):
13287 (Fremove_list_of_text_properties): Remove decls.
13288 * keyboard.c (Fthis_command_keys): Remove decl.
13289 (Fcommand_execute): New forward static decl.
13290 * keymap.c (Flookup_key): New forward static decl.
13291 (Fcopy_keymap): Now static.
13292 * keymap.h (Flookup_key): Remove decl.
13293 * process.c (Fget_process): New forward static decl.
13294 (Fprocess_datagram_address): Mark as internal.

13305 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13307 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13310 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13312 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13313 when at ZV. (Bug#8487)
13315 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13317 * charset.c (Fclear_charset_maps): Use xfree instead of free.

13320 * sound.c (sound_cleanup, alsa_close): Likewise.
13321 * termcap.c (tgetent): Likewise.
13322 * xfns.c (x_default_font_parameter): Likewise.
13323 * xsettings.c (read_and_apply_settings): Likewise.
13325 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13326 (overrun_check_free): Protoize.
13328 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13330 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13331 since callers should never pass a negative size.
13332 Change the signature to match that of plain 'read' and 'write'; see
13333 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13334 * lisp.h: Update prototypes of emacs_write and emacs_read.
13336 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13338 * xdisp.c (redisplay_window): Don't try to determine the character
13339 position of the scroll margin if the window start point w->startp
13340 is outside the buffer's accessible region. (Bug#8468)
13342 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13344 Fix write-region and its subroutines for buffers > 2GB.
13345 * fileio.c (a_write, e_write): Modify declaration of arguments and
13346 local variables to support buffers larger than 2GB.
13347 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13349 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13350 argument, local variables, and return value.
13352 * lisp.h: Update prototypes of emacs_write and emacs_read.
13354 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13356 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13358 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13360 Fix more problems found by GCC 4.6.0's static checks.
13362 * xdisp.c (vmessage): Use a better test for character truncation.
13364 * charset.c (load_charset_map): <, not <=, for optimization,
13365 and to avoid potential problems with integer overflow.
13366 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13367 * casetab.c (set_identity, shuffle): Likewise.
13368 * editfns.c (Fformat): Likewise.
13369 * syntax.c (skip_chars): Likewise.
13371 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13372 This also lets GCC 4.6.0 generate slightly better loop code.
13374 * callint.c (Fcall_interactively): <, not <=, for optimization.
13375 (Fcall_interactively): Count the number of arguments produced,
13376 not the number of arguments given. This is simpler and lets GCC
13377 4.6.0 generate slightly better code.
13379 * ftfont.c: Distingish more carefully between FcChar8 and char.
13380 The previous code passed unsigned char * to a functions like
13381 strlen and xstrcasecmp that expect char *, which does not
13382 conform to the C standard.
13383 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13384 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13385 char * when the C standard requires it.
13387 * keyboard.c (read_char): Remove unused var.
13389 * eval.c: Port to Windows vsnprintf (Bug#8435).
13390 Include <limits.h>.
13391 (SIZE_MAX): Define if the headers do not.
13392 (verror): Do not give up if vsnprintf returns a negative count.
13393 Instead, grow the buffer. This ports to Windows vsnprintf, which
13394 does not conform to C99. Problem reported by Eli Zaretskii.
13395 Also, simplify the allocation scheme, by avoiding the need for
13396 calling realloc, and removing the ALLOCATED variable.
13398 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13400 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13401 But keep the doprint source code for now, as we might revamp it
13402 and use it again (Bug#8435).
13403 * lisp.h (doprnt): Remove.
13404 * Makefile.in (base_obj): Remove doprnt.o.
13405 * deps.mk (doprnt.o): Remove.
13407 error: Print 32- and 64-bit integers portably (Bug#8435).
13408 Without this change, on typical 64-bit hosts error ("...%d...", N)
13409 was used to print both 32- and 64-bit integers N, which relied on
13410 undefined behavior.
13411 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13412 * lisp.h (error, verror): Mark as printf-like functions.
13413 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13414 Report overflow in size calculations when allocating printf buffer.
13415 Do not truncate output string at its first null byte.
13416 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13417 Truncate the output at a character boundary, since vsnprintf does not
13419 * charset.c (check_iso_charset_parameter): Convert internal
13420 character to string before calling 'error', since %c now has the
13422 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13423 overflow when computing char to be passed to 'error'. Do not
13424 pass Lisp_Object to 'error'; pass the integer instead.
13425 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13426 formatted with plain %d.
13428 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13430 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13432 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13434 * xterm.c (x_catch_errors): Remove duplicate declaration.
13436 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13438 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13440 2011-04-10 Jim Meyering <meyering@redhat.com>
13442 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13443 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13444 return ssize_t not "int", and use size_t as the buffer length.
13445 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13446 * gnutls.h: Update declarations.
13447 * process.c (read_process_output): Use ssize_t, to match.
13448 (send_process): Likewise.
13450 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13452 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13454 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13456 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13457 Use unsigned char, to match FcChar8 type definition.
13459 * xterm.c (handle_one_xevent):
13460 * xmenu.c (create_and_show_popup_menu):
13461 * xselect.c (x_decline_selection_request)
13462 (x_reply_selection_request): Avoid type-punned deref of X events.
13464 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13466 Fix some uses of `int' instead of EMACS_INT.
13467 * search.c (string_match_1, fast_string_match)
13468 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13469 (scan_buffer, find_next_newline_no_quit)
13470 (find_before_next_newline, search_command, Freplace_match)
13471 (Fmatch_data): Make some `int' variables be EMACS_INT.
13473 * xdisp.c (display_count_lines): 3rd argument and return value now
13474 EMACS_INT. All callers changed.
13475 (pint2hrstr): Last argument is now EMACS_INT.
13477 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13478 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13479 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

13490 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13491 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13493 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13494 (encode_invocation_designation): Last argument P_NCHARS is now
13496 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13497 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13499 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13502 * ccl.c (Fccl_execute_on_string): Declare some variables
13505 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13507 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13509 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13511 * process.c (Fformat_network_address): Doc fix.
13513 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)

13521 (Qhelp_form_show): New var.
13522 (syms_of_keyboard): Use DEFSYM macro.
13524 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13537 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13539 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13541 Fix more problems found by GCC 4.6.0's static checks.
13543 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

13547 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13549 * xdisp.c (vmessage): Mark as a printf-like function.
13551 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

13556 printf-like functions.
13557 (tiff_load): Add casts to remove these marks before passing them
13558 to system-supplied API.
13560 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13562 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13563 This avoids several warnings with gcc -Wstrict-overflow.
13564 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13565 directly, rather than having caller test rule sign. This avoids
13566 some unnecessary tests.
13567 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13568 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13569 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13571 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13572 (xfont_open): Avoid unnecessary tests.
13574 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13576 * composite.h, composite.c (composition_gstring_put_cache):
13577 Use EMACS_INT, not int, for length.
13579 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13580 breaking out part of COMPOSITION_DECODE_RULE.
13581 (COMPOSITION_DECODE_RULE): Use it.
13582 * composite.c (get_composition_id): Remove unused local vars,
13583 by using the new macro.
13585 * textprop.c (set_text_properties_1): Change while to do-while,
13586 since the condition is always true at first.
13588 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13589 (interval_deletion_adjustment): Return unsigned value.
13592 * process.c (list_processes_1, create_pty, read_process_output):
13593 (exec_sentinel): Remove vars that were set but not used.
13594 (create_pty): Remove unnecessary "volatile"s.
13595 (Fnetwork_interface_info): Avoid possibility of int overflow.
13596 (read_process_output): Do adaptive read buffering even if carryover.
13597 (read_process_output): Simplify nbytes computation if buffered.

13602 (update_syntax_table): Use unsigned instead of int.
13604 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13605 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.

13608 * print.c (print_error_message): Avoid int overflow.
13610 * font.c (font_list_entities): Redo for clarity,
13611 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13613 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13614 (font_score): Avoid potential overflow in diff calculation.
13616 * fns.c (substring_both): Remove var that is set but not used.
13617 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13619 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13621 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13622 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13623 can always succeed if overflow has undefined behavior.
13625 * search.c (boyer_moore, wordify): Remove vars set but not used.
13626 (wordify): Omit three unnecessary tests.
13628 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13629 All callers changed. This avoids the need for an unused var.
13631 * casefiddle.c (casify_region): Remove var that is set but not used.
13633 * dired.c (file_name_completion): Remove var that is set but not used.
13635 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13637 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13638 (Finsert_file_contents): Remove unnecessary code checking fd.
13640 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13641 Check for integer overflow on size calculations.
13643 * buffer.c (Fprevious_overlay_change): Remove var that is set
13646 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13647 Remove vars that are set but not used.
13648 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13649 (timer_check_2): Mark vars as initialized.
13651 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13653 * image.c (lookup_image): Remove var that is set but not used.
13654 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13656 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13657 that are set but not used.
13659 * xfns.c (make_invisible_cursor): Don't return garbage
13660 if XCreateBitmapFromData fails (Bug#8410).
13662 * xselect.c (x_get_local_selection, x_handle_property_notify):
13663 Remove vars that are set but not used.
13665 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13666 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13668 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13669 Remove var that is set but not used.
13670 (scroll_bar_windows_size): Now size_t, not int.
13671 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13672 Check for overflow.
13674 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13675 (map_tty_color) [!defined MSDOS]: Likewise.
13677 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13679 * coding.c: Remove vars that are set but not used.
13680 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13681 All callers changed.
13682 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13683 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13684 (decode_coding_charset): Remove vars that are set but not used.
13686 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13687 that is set but not used.
13689 * print.c (print_object): Remove var that is set but not used.
13691 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13692 The gnulib version avoids calling malloc in the usual case,
13693 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13694 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13695 * filelock.c (current_lock_owner): Likewise.
13696 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13697 * sysdep.c: Include allocator.h, careadlinkat.h.
13698 (emacs_no_realloc_allocator): New static constant.
13699 (emacs_readlink): New function.
13700 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13701 ../lib/careadlinkat.h.
13703 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13705 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13706 first non-nil return value).
13708 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13710 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13711 if not defined (Bug#8403).
13713 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13715 * xdisp.c (display_count_lines): Remove parameter `start',
13716 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13717 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13718 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13720 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13721 and thereabouts. All callers changed.
13722 (get_per_char_metric): Remove parameter `f', unused since
13723 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13725 2011-04-02 Jim Meyering <meyering@redhat.com>
13727 do not dereference NULL upon failed strdup
13728 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13729 (ns_get_family): Likewise.
13731 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13733 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13735 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13737 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13740 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13742 Add lexical binding.
13744 * window.c (Ftemp_output_buffer_show): New fun.
13745 (Fsave_window_excursion):
13746 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13748 * lread.c (lisp_file_lexically_bound_p): New function.
13749 (Fload): Bind Qlexical_binding.
13750 (readevalloop): Remove `evalfun' arg.
13751 Bind Qinternal_interpreter_environment.
13752 (Feval_buffer): Bind Qlexical_binding.
13753 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13755 (syms_of_lread): Declare `lexical-binding'.
13757 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13759 * keyboard.c (eval_dyn): New fun.
13760 (menu_item_eval_property): Use it.
13762 * image.c (parse_image_spec): Use Ffunctionp.
13764 * fns.c (concat, mapcar1): Accept byte-code-functions.
13766 * eval.c (Fsetq): Handle lexical vars.
13767 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13768 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13769 (FletX, Flet): Obey lexical binding.
13770 (Fcommandp): Handle closures.
13771 (Feval): New `lexical' arg.
13772 (eval_sub): New function extracted from Feval. Use it almost
13773 everywhere where Feval was used. Look up vars in lexical env.
13775 (Ffunctionp): Move from subr.el.
13776 (Ffuncall): Handle closures.
13777 (apply_lambda): Remove `eval_flags'.
13778 (funcall_lambda): Handle closures and new byte-code-functions.
13779 (Fspecial_variable_p): New function.
13780 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13781 but without exporting it to Lisp.
13783 * doc.c (Fdocumentation, store_function_docstring):
13784 * data.c (Finteractive_form): Handle closures.
13786 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13789 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13791 (exec_byte_code): New function extracted from Fbyte_code to handle new
13792 calling convention for byte-code-functions. Add new byte-codes.
13794 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13796 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13798 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13800 * xdisp.c (redisplay_internal): Fix prototype.
13802 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13804 * xdisp.c (SCROLL_LIMIT): New macro.
13805 (try_scrolling): Use it when setting scroll_limit.
13806 Limit scrolling to 100 screen lines.
13807 (redisplay_window): Even when falling back on "recentering",
13808 position point in the window according to scroll-conservatively,
13809 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13811 (try_scrolling): When point is above the window, allow searching
13812 as far as scroll_max, or one screenful, to compute vertical
13813 distance from PT to the scroll margin position. This prevents
13814 try_scrolling from unnecessarily failing when
13815 scroll-conservatively is set to a value slightly larger than the
13816 window height. Clean up the case of PT below the margin at bottom
13817 of window: scroll_max can no longer be INT_MAX. When aggressive
13818 scrolling is in use, don't let point enter the opposite scroll
13819 margin as result of the scroll.
13820 (syms_of_xdisp) <scroll-conservatively>: Document the
13821 threshold of 100 lines for never-recentering scrolling.
13823 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13825 * dispextern.h (move_it_by_lines):
13826 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13827 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13828 (message_log_check_duplicate): Remove parameters `prev_bol' and
13829 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13830 (redisplay_internal): Remove parameter `preserve_echo_area',
13831 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13833 * indent.c (Fvertical_motion):
13834 * window.c (window_scroll_pixel_based, Frecenter):
13835 Don't pass `need_y_p' to `move_it_by_lines'.
13837 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13839 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13840 steal a few bits to be more compact.
13841 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13842 Remove unneeded casts.
13844 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13846 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13848 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13849 binding" message (bug#7967).
13851 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13853 Fix more problems found by GCC 4.6.0's static checks.
13855 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13856 Remove unused local var.
13858 * editfns.c (Fmessage_box): Remove unused local var.
13860 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13861 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13862 Omit unused local vars.
13863 * window.c (shrink_windows): Omit unused local var.
13864 * menu.c (digest_single_submenu): Omit unused local var.
13865 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13866 Omit unused local var.
13868 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13869 Don't assume string length fits in int.
13870 (keyremap_step, read_key_sequence): Use size_t for sizes.
13871 (read_key_sequence): Don't check last_real_key_start redundantly.
13873 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13874 instead of alloca (Bug#8344).
13876 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13877 (Fbacktrace_frame): Don't assume nframes fits in int.
13879 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13881 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13884 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13886 * cm.c (calccost): Turn while-do into do-while, for clarity.
13888 * keyboard.c (syms_of_keyboard): Use the same style as later
13889 in this function when indexing through an array. This also
13890 works around GCC bug 48267.
13892 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13894 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13896 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13897 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13899 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13900 This avoids undefined behavior on integer overflow, and is a bit
13901 more convenient anyway since it is compared to a size_t variable.
13903 Variadic C functions now count arguments with size_t, not int.
13904 This avoids an unnecessary limitation on 64-bit machines, which
13905 caused (substring ...) to crash on large vectors (Bug#8344).
13906 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13907 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13908 All variadic functions and their callers changed accordingly.

13915 * fns.c (concat): Likewise.
13916 * frame.c (x_set_frame_parameters): Likewise.
13917 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13918 0 if not found, not -1. All callers changed.
13920 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13921 (stack_copy_size): Now size_t, not int.
13922 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13924 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13926 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13927 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13928 All callers changed.
13930 * lisp.h (multibyte_char_to_unibyte):
13931 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13932 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13936 * keymap.c (push_key_description):
13937 * search.c (Freplace_match):
13938 * xdisp.c (message_dolog, set_message_1): All callers changed.
13940 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13942 * keyboard.c (safe_run_hook_funcall): New function.
13943 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13944 don't set the hook to nil, but remove the offending function instead.
13945 (Qcommand_hook_internal): Remove, unused.
13946 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13947 Vcommand_hook_internal.
13949 * eval.c (enum run_hooks_condition): Remove.
13950 (funcall_nil, funcall_not): New functions.
13951 (run_hook_with_args): Call each function through a `funcall' argument.
13952 Remove `cond' argument, now redundant.
13953 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13954 (Frun_hook_with_args_until_failure): Adjust accordingly.
13955 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
13957 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13959 * dispextern.h (string_buffer_position): Remove declaration.
13961 * print.c (strout): Remove parameter `multibyte', unused since
13962 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13964 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13965 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13966 All callers changed.
13968 * w32.c (_wsa_errlist): Use braces for struct initializers.

14127 * buffer.c (Fkill_all_local_variables):
14128 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14130 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14131 unconditionally since it does the check itself.
14133 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14135 Fix more problems found by GCC 4.5.2's static checks.
14137 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14138 the first time through the loop, since we know p0 < p1 then.
14139 This also avoids a gcc -Wstrict-overflow warning.
14141 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14142 leading to a memory leak, possible in functions like
14143 load_charset_map_from_file that can allocate an unbounded number
14144 of objects (Bug#8318).
14146 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14147 that could (at least in theory) be that large.
14149 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14150 This is less likely to overflow, and avoids undefined behavior if
14151 overflow does occur. All callers changed. Use strtoul to scan
14152 for the unsigned long integer.
14153 (pint2hrstr): Simplify and tune code slightly.
14154 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14169 * process.c (Fmake_network_process): Use socklen_t, not int,
14170 where POSIX says socklen_t is required in portable programs.
14171 This fixes a porting bug on hosts like 64-bit HP-UX, where
14172 socklen_t is wider than int (Bug#8277).
14173 (Fmake_network_process, server_accept_connection):
14174 (wait_reading_process_output, read_process_output):
14177 * process.c: Rename or move locals to avoid shadowing.

14187 Make tparam.h and terminfo.c consistent.
14188 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14189 Include tparam.h instead, since it declares them.
14190 * cm.h (PC): Remove extern decl; tparam.h now does this.
14191 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14192 * terminfo.c: Include tparam.h, to check interfaces.
14193 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14194 (tparam): Adjust signature to match interface in tparam.h;
14195 this removes some undefined behavior. Check that outstring and len
14196 are zero, which they always are with Emacs.
14197 * tparam.h (PC, BC, UP): New extern decls.
14199 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14200 (xftfont_open): Rename locals to avoid shadowing.

14217 (find_automatic_composition, composition_adjust_point): Likewise.
14218 (composition_update_it): Mark var as initialized.
14219 (find_automatic_composition): Mark vars as initialized,
14220 with a FIXME (Bug#8290).

14224 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14225 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14226 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14227 to avoid shadowing.

14239 Fix pointer signedness.
14240 (alsa_choose_format): Remove unused local var.
14241 (wav_play): Initialize a variable to 0, to prevent undefined
14242 behavior (Bug#8278).
14244 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14246 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14248 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14249 clobbering (Bug#8298).
14250 * sysdep.c (sys_subshell): Likewise.
14251 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14253 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14254 This should get cleaned up, so that child_setup has the
14255 same signature on all platforms.
14257 * callproc.c (call_process_cleanup): Now static.
14258 (relocate_fd): Rename locals to avoid shadowing.
14260 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14262 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14263 not to be necessary, and produces flickering.
14265 2011-03-20 Glenn Morris <rgm@gnu.org>
14267 * config.in: Remove file.
14269 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

14314 Define only if needed.
14316 * unexelf.c (unexec): Name an expression,
14317 to avoid gcc -Wbad-function-cast warning.
14318 Use a different way to cause a compilation error if anyone uses
14319 n rather than nn, a way that does not involve shadowing.
14320 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14322 * deps.mk (unexalpha.o): Remove; unused.

14424 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14426 Use functions, not macros, for up- and down-casing (Bug#8254).
14427 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14428 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14429 to use the following functions instead of these macros.
14430 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14431 EMACS_INT, since callers assume the returned value fits in int.
14432 (upcase1): Likewise, for UPCASE_TABLE.
14433 (uppercasep, lowercasep, upcase): New static inline functions.
14434 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14435 the race-condition problem in the old DOWNCASE.
14437 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
14438 Rename locals to avoid shadowing.
14439 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14440 (regex_compile, re_search_2, re_match_2_internal):
14441 Remove unused local vars.
14442 (FREE_VAR): Rewrite so as not to use empty "else",
14443 which gcc can warn about.
14444 (regex_compile, re_match_2_internal): Mark locals as initialized.
14445 (RETALLOC_IF): Define only if needed.
14446 (WORDCHAR_P): Likewise. This one is never needed, but is used
14447 only in a comment talking about a compiler bug, so put inside
14448 the #if 0 of that comment.
14449 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14450 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14453 * search.c (boyer_moore): Rename locals to avoid shadowing.
14454 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

14465 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
14467 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14468 Rename locals to avoid shadowing.
14469 (Fvertical_motion): Mark locals as initialized.
14471 * casefiddle.c (casify_object, casify_region): Now static.
14472 (casify_region): Mark local as initialized.
14474 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14476 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14477 New macros, so that the caller can use some names other than
14478 gcpro1, gcpro2, etc.
14479 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14481 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14482 argument, for consistency with GCPRO2_VAR, etc: it is now the
14483 prefix of the variable, not the variable itself. All uses
14485 * dired.c (directory_files_internal, file_name_completion):
14486 Rename locals to avoid shadowing.
14488 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14489 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14490 dired.c's scmp function, had undefined behavior.
14491 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14492 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14493 * buffer.h: ... to here, because these macros use current_buffer,
14494 and the new implementation with inline functions needs to have
14495 current_buffer in scope now, rather than later when the macros
14497 (downcase, upcase1): New static inline functions.
14498 (DOWNCASE, UPCASE1): Reimplement using these functions.
14499 This avoids undefined behavior in expressions like
14500 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14501 from race conditions in accessing the global variables
14502 case_temp1 and case_temp2.
14503 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14504 * lisp.h (case_temp1, case_temp2): Remove their decls.
14505 * character.h (ASCII_CHAR_P): Move from here ...
14506 * lisp.h: ... to here, so that the inline functions mentioned
14507 above can use them.
14509 * dired.c (directory_files_internal_unwind): Now static.
14511 * fileio.c (file_name_as_directory, directory_file_name):
14512 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14514 (file_name_as_directory): Use const pointers when appropriate.
14515 (Fexpand_file_name): Likewise. In particular, newdir might
14516 point at constant storage, so make it a const pointer.
14517 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14518 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14520 (Fset_file_times, Finsert_file_contents, auto_save_error):

14525 to avoid shadowing.
14527 * marker.c (bytepos_to_charpos): Remove; unused.
14529 * lisp.h (verify_bytepos, count_markers): New decls,
14530 so that gcc does not warn that these functions aren't declared.
14532 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14533 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14534 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14535 (copy_text): Remove unused local var.
14537 * filelock.c (within_one_second): Now static.
14538 (lock_file_1): Rename local to avoid shadowing.
14540 * buffer.c (fix_overlays_before): Mark locals as initialized.
14541 (fix_start_end_in_overlays): Likewise. This function should be
14542 simplified by using pointers-to-pointers, but that's a different
14544 (switch_to_buffer_1): Now static.
14545 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14546 (report_overlay_modification): Rename locals to avoid shadowing.
14548 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14549 Fix pointer signedness issue.
14550 (sys_subshell): Mark local as volatile if checking for lint,
14551 to suppress a gcc -Wclobbered warning that does not seem to be right.
14552 (MAXPATHLEN): Define only if needed.
14554 * process.c (serial_open, serial_configure): Move decls from here ...
14555 * systty.h: ... to here, so that they can be checked.
14557 * fns.c (get_random, seed_random): Move extern decls from here ...
14558 * lisp.h: ... to here, so that they can be checked.
14560 * sysdep.c (reset_io): Now static.
14561 (wait_for_termination_signal): Remove; unused.
14563 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14564 (copy_keymap_item, append_key, push_text_char_description):
14566 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14567 (DENSE_TABLE_SIZE): Remove; unused.
14568 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14569 (describe_map_tree):
14570 Rename locals to avoid shadowing.
14572 * keyboard.c: Declare functions static if they are not used elsewhere.

14721 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14722 reports time overflow. See
