152 * w32.c (init_environment): Change the default values of many
153 environment variables in dflt_envvars[] to NULL, to avoid pushing
154 them into environment when they were not already defined. Remove
155 the code that deletes site-lisp subdirectories from the default
156 value of EMACSLOADPATH, as it is no longer needed.
157 (check_windows_init_file): Now external, not static. Use
158 Vload_path as is, without adding anything, as this function is now
159 called when Vload_path is already set up.
161 * w32.h (check_windows_init_file): Add prototype.
163 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

168 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
169 any, in the DEFALT argument into the root of the Emacs build or
170 installation tree, as appropriate.
172 * callproc.c (init_callproc_1): Call decode_env_path instead of
173 doing its equivalent by hand.
174 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
175 the code that sets Vexec_path run on MS-Windows.
177 * lread.c (init_lread): Add comments to #ifdef's.
179 * msdos.c (dos_set_window_size, IT_update_begin)

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

206 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
207 Remove unnecessary pointer casts.
208 * alloc.c (record_xmalloc): New function.
209 * lisp.h (record_xmalloc): New decl.
210 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
211 more like a function. This is because the pointer cast is not
212 needed. All uses changed.
213 * print.c (print_string, print_error_message): Avoid length recalc.
215 Improve fix for macroexp crash with debugging (Bug#12118).
216 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
217 ARRAY_MARK_FLAG when checking subscripts, because ASET is
218 not supposed to be invoked from the garbage collector.
219 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
220 (gc_aset): New function, which is like ASET but can be
221 used in the garbage collector.

234 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
235 (map_w32_filename): Improve commentary. Simplify switch.
236 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
237 headers (most versions of MinGW w32api don't).
238 (get_security_info, create_symbolic_link)
239 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
241 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
242 in the argument file name.

244 GetFileAttributes fails with network-related error codes.
245 (sys_rename): Diagnose renaming of a symlink when the user doesn't
246 have the required privileges.
247 (get_file_security_desc_by_name): Renamed from
248 get_file_security_desc.
249 (stat_worker): New function, with most of the guts of 'stat', and
250 with addition of handling of symlinks and support for 'lstat'. If
251 possible, get file's attributes and security information by
252 handle, not by name. Produce S_IFLNK bit for symlinks, when
254 (stat, lstat): New functions, call 'stat_worker'.
255 (symlink, readlink, careadlinkat): Rewritten to create and resolve
256 symlinks when the underlying filesystem supports them.
258 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
260 Fix macroexp crash on Windows with debugging (Bug#12118).
261 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
262 checking subscripts; problem introduced with the recent
263 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
264 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
265 since it's used in non-static inline functions now.
267 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
268 Don't assume buffer size fits in 'int'. Remove unused local.
270 Use C99-style 'extern inline' if available.
271 * buffer.h (BUFFER_INLINE):
272 * category.h (CATEGORY_INLINE):

288 * composite.c (COMPOSITE_INLINE):
289 * dispnew.c (DISPEXTERN_INLINE):
290 * sysdep.c (SYSTIME_INLINE):
291 Define to EXTERN_INLINE, so that the corresponding functions
292 are compiled into code.
293 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
294 (INLINE_HEADER_END): New macros.
295 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

317 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
319 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
320 This how ASET and AREF are supposed to work, and makes
321 it easier to think about future improvements. See
322 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
323 * charset.h (set_charset_attr): New function.

735 * alloc.c (listn): Fix the order the arguments are consed onto the
738 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
739 enumeration constants, as PURE and HEAP are too general, and clash
740 with other headers and sources, such as gmalloc.c and the
741 MS-Windows system headers. All users changed.
743 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
745 Revert last save_excursion_save and save_excursion_restore changes.
746 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

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

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

790 * xfns.c (syms_of_xfns): Likewise.
792 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

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

827 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
828 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
829 not be usable in #if. This simplifies things.
831 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
833 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
835 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

838 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
839 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
840 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
841 Adjust to changes in lisp.h and emacs.c, by using
842 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
843 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
844 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
845 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
846 instead of gdb_valbits.
847 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
848 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
849 instead of gdb_array_mark_flag.
850 (xboolvector): Get size from $->size, not $->header.size.
851 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
852 (xreload, hook-run, hookpost-run): Remove.
853 * emacs.c: Include <verify.h>.
854 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
855 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
857 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
858 (gdb_USE_LSB_TAG): New enum constants.
859 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
860 Also define these as enum constants, so they're visible to GDB.
861 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
862 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
863 as constants, so they're visible to GDB.
864 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
865 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
866 Now enum constants, not macros, so they're visible to GDB.
867 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
868 more convenient now. All uses changed.
869 (VALMASK) [USE_LSB_TAG]: Also define in this case.

880 add argument, tune behavior, and adjust all callers.
882 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
884 Use typedef for EMACS_INT, EMACS_UINT.
885 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
886 than macros. This simplifies debugging in the usual case, since
887 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
888 and it allows expressions involving EMACS_INT casts.
889 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
891 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
893 * nsterm.m (ns_read_socket): Return early if there is a modal

903 Adjust buffer text indirection counters at the end of Fkill_buffer.
904 * buffer.c (Fkill_buffer): Adjust indirection counters when the
905 buffer is definitely dead. This should really fix an issue reported
906 by Christoph Scholtes again. (Bug#12007).
907 (init_buffer_once): Initialize indirection counters of
908 buffer_defaults and buffer_local_symbols (for sanity and safety).
910 2012-07-24 Eli Zaretskii <eliz@gnu.org>
912 * xdisp.c (init_iterator): Don't compute dimensions of truncation
913 and continuation glyphs on tooltip frames, leave them at zero.
914 Avoids continued lines in tooltips. (Bug#11832)
916 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
918 Simplify copy_overlay.
919 * buffer.c (copy_overlay): Simplify. Use build_marker.

1753 * nsterm.m (ns_term_init):
1754 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1755 * nsterm.m (ns_term_init):
1756 Avoid the need for strncpy, by using build_string or
1757 make_unibyte_string directly. Use dtoastr, not snprintf.
1758 * process.c (Fmake_network_process): Diagnose service names that
1759 are too long, rather than silently truncating them or creating

1829 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1830 We include usg5-4-common.h, which defines them both.
1832 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1833 O_RDONLY already includes it).
1835 Stop ns builds setting the EMACSLOADPATH environment variable.
1836 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1837 Now it does not set EMACSLOADPATH, just returns the load-path string.
1838 * nsterm.h: Update accordingly.
1839 * lread.c [HAVE_NS]: Include nsterm.h.
1840 (init_lread) [HAVE_NS]: Use ns_load_path.
1841 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1843 2012-07-09 Glenn Morris <rgm@gnu.org>
1845 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1846 since the included bsd-common.h does so.
1848 Stop ns builds setting the EMACSPATH environment variable.
1849 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1850 (ns_init_paths): Do not set EMACSPATH.
1851 * nsterm.h (ns_exec_path): Add it.
1852 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1855 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1857 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1859 * process.c (wait_reading_process_output): 'waitchannels' was unset
1860 when read_kbd || !NILP (wait_for_cell); fix this.
1862 Add GCC-style 'const' attribute to functions that can use it.
1863 * character.h (char_resolve_modifier_mask):
1864 * keyboard.h (make_ctrl_char):
1865 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1866 (init_character_once, next_almost_prime, init_fns, init_image)
1867 (flush_pending_output, init_sound):
1868 * mem-limits.h (start_of_data):
1869 * menu.h (finish_menu_items):
1870 Add ATTRIBUTE_CONST.
1871 * emacs.c (DEFINE_DUMMY_FUNCTION):
1872 Declare the dummy function with ATTRIBUTE_CONST.
1873 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1874 Add decls with ATTRIBUTE_CONST.
1876 Minor improvements to make_formatted_string.
1877 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1878 where int is good enough, as vsprintf returns an int.
1879 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1881 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1883 Use make_formatted_string to avoid double length calculation.
1884 * lisp.h (make_formatted_string): New prototype.
1885 * alloc.c (make_formatted_string): New function.
1886 * buffer.c (Fgenerate_new_buffer_name): Use it.
1887 * dbus.c (syms_of_dbusbind): Likewise.
1888 * editfns.c (Fcurrent_time_zone): Likewise.
1889 * filelock.c (get_boot_time): Likewise.
1890 * frame.c (make_terminal_frame, set_term_frame_name)
1891 (x_report_frame_params): Likewise.
1892 * image.c (gs_load): Likewise.
1893 * minibuf.c (get_minibuffer): Likewise.

1903 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
1904 * nsterm.h (ns_etc_directory): Add it.
1905 * callproc.c [HAVE_NS]: Include nsterm.h.
1906 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1908 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1910 Move marker debugging code under MARKER_DEBUG.
1911 * marker.c (MARKER_DEBUG): Move marker debugging code under
1912 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1913 for bootstrap with --enable-checking (~3x slowdown reported
1914 by Juanma Barranquero <lekktu@gmail.com>).
1915 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1917 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1919 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1920 See <http://bugs.gnu.org/11825#29>.
1922 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1924 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1925 has no font, use the frame's font. (Bug#11813)
1926 (display_line): Add commentary about displaying truncation glyphs
1928 (produce_special_glyphs): Move here from term.c.
1930 * term.c (produce_special_glyphs): Move to xdisp.c.
1932 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1935 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1937 * xdisp.c (display_line): Avoid warning about implicit declaration
1940 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1942 * lisp.h: Remove empty conditional.
1944 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1946 * lread.c (load_path_check): Now static.
1948 Fix some minor --with-ns problems found by static checking.
1949 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1950 (x_set_font) [!HAVE_X_WINDOWS]:
1951 * image.c (xpm_load_image) [HAVE_NS]:
1952 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1953 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1954 Remove unused local.
1955 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1956 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1957 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1958 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1959 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1960 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1961 Fix pointer signedness problem.
1962 * xfaces.c (FRAME_X_FONT_TABLE):
1963 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1965 2012-07-07 Glenn Morris <rgm@gnu.org>
1967 * lread.c (load_path_check): New function, split from init_lread.
1968 (init_lread): Reorganize. Motivation:
1969 If EMACSLOADPATH is set, check/warn about that rather than the
1970 defaults, which we are not going to use. Hence we can remove
1971 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1972 Don't warn if site-lisp directories are missing.
1973 If not installed, start from a blank load-path, since
1974 PATH_LOADSEARCH refers to the eventual installation directories.
1976 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1978 Support truncation and continuation glyphs on GUI frames, when
1979 fringes are disabled. (Bug#11832)
1980 * xdisp.c (init_iterator): Get dimensions of truncation and
1981 continuation glyphs even if on GUI frames. Adjust
1982 it->last_visible_x on GUI frames when the left or right fringes,
1983 or both, are absent.
1984 (start_display, move_it_in_display_line_to): Handle the case of a
1985 GUI frame without a fringe to display continuation or truncation
1987 (insert_left_trunc_glyphs): Support GUI frames: make sure
1988 truncation glyphs overwrite enough glyphs from the current line to
1989 have sufficient space in pixels.
1990 (display_line): Support truncation and continuation glyphs on GUI
1991 frames. If some spare pixels are left on the line after inserting
1992 the truncation glyphs, fill that space with a stretch glyph of a
1993 suitably computed width.
1995 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1996 produce_glyphs, to support GUI sessions.
1998 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2000 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2002 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2004 Do not require float-time's arg to fit in time_t (Bug#11825).
2005 This works better on hosts where time_t is unsigned, and where
2006 float-time is applied to the (negative) difference between two times.
2007 * editfns.c (decode_time_components): Last arg is now double *,
2008 not int *, and means to store all the result as a double, without
2009 worrying about whether the seconds part fits in time_t.
2010 All callers changed.
2011 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2012 All callers changed.
2013 (Ffloat_time): Do not fail merely because the specified time falls
2014 outside of time_t range.
2016 2012-07-07 Glenn Morris <rgm@gnu.org>
2018 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
2019 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

2022 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2024 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2025 Update dependencies.
2027 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2029 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2031 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
2032 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
2033 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2034 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2035 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2036 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2038 * xfont.c (compare_font_names): Redo to omit the need for casts.
2040 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2042 * xfns.c (Fx_change_window_property): Doc fix.
2043 * w32fns.c (Fx_change_window_property): Doc fix.
2045 * w32fns.c (Fx_window_property): Accept the same arguments as the
2046 X Windows version. Doc fix.
2047 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2049 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2050 Eli Zaretskii <eliz@gnu.org>
2052 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2053 Windows-specific code from nt/config.nt moved here.
2054 Obsolete settings removed.
2056 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2058 * process.c: Avoid unnecessary calls to gettime.
2059 (wait_reading_process_output): Don't get the time of day
2060 when gobbling data immediately and not waiting, as there's no need
2061 for it in that case. This removes a FIXME.
2063 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2065 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2066 is defined (Bug#11768).
2068 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2070 Fix marker debugging code.
2071 * marker.c (byte_char_debug_check): Do not perform the check
2072 if buffer is not multibyte.
2073 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2074 Call byte_char_debug_check with correct arguments.
2076 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2078 Compile marker debugging code only if ENABLE_CHECKING is defined.
2079 * marker.c (byte_char_debug_check, count_markers):
2080 Use only if ENABLE_CHECKING is defined.
2081 (byte_debug_flag): Remove.
2082 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2083 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2085 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2087 Avoid code repetition in marker-related functions.
2088 * marker.c (attach_marker): New function.
2089 (Fset_marker, set_marker_restricted, set_marker_both)
2090 (set_marker_restricted_both): Use it.
2091 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2092 Consistently rename charno to charpos.
2093 (marker_position): Add eassert.
2094 (marker_byte_position): Convert to eassert.

2106 * lisp.h (build_marker): New prototype.
2107 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
2108 * composite.c (autocmp_chars): Likewise.
2109 * editfns.c (buildmark): Remove.
2110 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2111 (save_restriction_save): Use build_marker.
2112 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2113 * window.c (save_window_save): Likewise.
2115 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2117 Do not use Fdelete_overlay in delete_all_overlays
2118 to avoid redundant calls to unchain_overlay.
2119 * buffer.c (drop_overlay): New function.
2120 (delete_all_overlays, Fdelete_overlay): Use it.
2121 * minibuf.c (get_minibuffer): Fix comment.
2123 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2125 Port to OpenBSD 5.1 amd64.
2126 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2127 This is needed for OpenBSD, and should be harmless on all BSD systems.
2128 Also, include <sys/sysctl.h>, as it should be available on all
2129 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2130 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2131 use p_pid member, not kp_proc.pid.
2133 2012-07-06 Glenn Morris <rgm@gnu.org>
2135 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2137 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2139 More xmalloc and related cleanup.
2140 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2141 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2146 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2147 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2148 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2150 Omit needless casts involving void * pointers and allocation.
2151 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2152 as the former is more robust if P's type is changed.
2153 Prefer xzalloc to xmalloc + memset 0.
2154 Simplify malloc-or-realloc to realloc.
2155 Don't worry about xmalloc returning a null pointer.
2156 Prefer xstrdup to xmalloc + strcpy.
2157 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2159 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2160 alloca of a constant.
2162 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2164 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2165 hscroll is larger than the line width. Fixes long and futile
2166 looping inside extend_face_to_end_of_line (on a TTY) producing
2167 glyphs that are not needed and thrown away.
2169 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2171 * marker.c (set_marker_restricted_both): Simplify by using
2174 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2185 followed by gtk_box_set_homogeneous (Bug#11768).
2186 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2187 (update_theme_scrollbar_width, xg_create_scroll_bar):
2188 Use gtk_scrollbar_new (Bug#11768).
2189 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2190 (is_box_type): New function (Bug#11768).
2191 (xg_tool_item_stale_p): Call is_box_type.
2192 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2193 with default display (Bug#11768).
2195 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2197 * xdisp.c (window_hscroll_limited): New function.
2198 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2199 coordinates when window's hscroll is set to insanely large
2202 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2204 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2205 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2207 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2210 * lisp.h (xzalloc): New prototype. Omit needless casts.
2211 * alloc.c (xzalloc): New function. Omit needless casts.

2266 Problem reported by Troels Nielsen in
2267 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2269 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2271 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2272 This should be fixed in a better way; see Eli Zaretskii in
2273 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2274 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2276 * fileio.c (time_error_value): Rename from special_mtime.
2277 The old name's problems were noted by Eli Zaretskii in
2278 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2280 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2281 This variable's comment says Emacs needs at least one GDB-visible
2282 symbol of type enum pvec_type, to work around GDB problems.
2283 The symbol's value doesn't matter.
2285 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2286 that causes compilation to fail on pre-C99 compilers.
2288 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2290 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2291 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2293 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

2296 headers for buffer_defaults and buffer_local_symbols.
2297 Reported by Juanma Barranquero <lekktu@gmail.com>.
2299 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2301 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2302 * lisp.h (enum pvec_type): Use fewer bits.
2303 (PSEUDOVECTOR_SIZE_BITS): New constant.
2304 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2305 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2306 change in pvec_type.
2307 (PSEUDOVECTOR_TYPEP): New macro.
2308 (TYPED_PSEUDOVECTORP): Use it.
2309 * fns.c (internal_equal): Adapt code to extract pvectype.
2310 * emacs.c (gdb_pvec_type): Update type.
2311 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2312 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2313 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2314 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2315 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2316 abusing vector->header.next.nbytes.
2317 (live_vector_p): Use PVEC_TYPE.
2318 (mark_object): Adapt code to extract pvectype. Use switch.
2320 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2322 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2323 Tighten new eassert a bit.
2325 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2327 Fix compilation with --enable-gcc-warnings and -O1
2329 * doprnt.c (doprnt): Change type of tem to int, initialize
2330 to avoid compiler warning. Add eassert.
2331 * search.c (simple_search): Initialize match_byte to avoid
2332 compiler warning. Add eassert.
2334 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2336 Avoid weird behavior with large horizontal scrolls.
2337 Without this change, for example, large hscroll values would
2338 mess up Emacs's display on Fedora 15 x86, presumably due to
2339 overflows in int calculations in the display code.
2340 Also, if buffers had long lines, Emacs would freeze.
2341 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2342 (set_window_hscroll): New function, containing the old guts of
2343 Fset_window_hscroll. Return the clipped value.
2344 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2345 This avoids the need to check against PTRDIFF_MAX.
2347 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2349 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2351 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2353 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2355 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2356 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2357 since GCC 4.4.6 issues a bogus warning for them.
2359 Fix bugs in file timestamp newness comparisons.
2360 * fileio.c (Ffile_newer_than_file_p):
2361 * lread.c (Fload): Use full timestamp resolution of files,
2362 not just the 1-second resolution, so that files that are only
2363 slightly newer still count as newer.
2364 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2365 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2367 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2369 * fileio.c: Improve handling of file time marker. (Bug#11852)
2370 (special_mtime): New function.
2371 (Finsert_file_contents, Fverify_visited_file_modtime):
2372 Use it to set special mtime values consistently.
2374 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2376 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2377 marker for non-existing file. (Bug#11852)
2379 2012-07-03 Glenn Morris <rgm@gnu.org>
2381 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2382 and did not make it into globals.h).
2384 2012-07-03 Tom Tromey <tromey@redhat.com>
2386 * window.c (Fset_window_margins, Fset_window_fringes)
2387 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2388 * textprop.c (Fprevious_property_change): No longer static.
2389 * syntax.c (Fsyntax_table_p): No longer static.
2390 * process.c (Fget_process, Fprocess_datagram_address): No longer

2404 * dired.c (Ffile_attributes): No longer static.
2405 * composite.c (Fcomposition_get_gstring): No longer static.
2406 * callproc.c (Fgetenv_internal): No longer static.
2408 * ccl.h: Remove EXFUNs.
2409 * buffer.h: Remove EXFUNs.
2410 * dispextern.h: Remove EXFUNs.
2411 * intervals.h: Remove EXFUNs.
2412 * fontset.h: Remove EXFUN.
2413 * font.h: Remove EXFUNs.
2414 * dosfns.c (system_process_attributes): Remove EXFUN.
2415 * keymap.h: Remove EXFUNs.
2416 * lisp.h: Remove EXFUNs.
2417 * w32term.h: Remove EXFUNs.
2418 * window.h: Remove EXFUNs.
2419 * xsettings.h: Remove EXFUN.
2420 * xterm.h: Remove EXFUN.
2422 2012-07-03 Glenn Morris <rgm@gnu.org>
2424 * lisp.h (Frandom): Make it visible to C.
2425 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2426 buffer for invisible buffers. (Bug#1229)
2428 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2430 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2431 values which aren't power of 2.
2432 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2433 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2436 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2438 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2440 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2442 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2444 * alloc.c (allocate_vector_block): Remove redundant
2445 calls to mallopt if DOUG_LEA_MALLOC is defined.
2446 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2447 avoid calls to mallopt if zero_vector is returned.
2449 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2451 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2452 is enabled, avoid dereferencing NULL current_sblock if
2455 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2457 Cleanup basic buffer management.
2458 * buffer.h (struct buffer): Change layout to use generic vector
2459 marking code. Fix some comments. Change type of 'clip_changed'
2460 to bitfield. Remove unused #ifndef old.
2461 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2462 (GET_OVERLAYS_AT): Fix indentation.
2463 (for_each_per_buffer_object_at): New macro.
2464 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2465 (Fbuffer_local_variables): Use it.
2466 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2467 * alloc.c (allocate_buffer): Adjust to match new layout of
2468 struct buffer. Fix comment.
2469 (mark_overlay): New function.
2470 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2471 Lisp area of struct buffer.
2472 (mark_object): Use it. Adjust marking of misc objects
2473 and related comments.
2475 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2477 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2478 wrapper that is not needed because the wrapped code is a no-op (zero
2479 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2480 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2482 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2484 * alloc.c (mark_buffer): Simplify. Remove prototype.
2485 (mark_object): Add comment. Reorganize marking of vector-like
2486 objects. Use CHECK_LIVE for all vector-like objects except buffers
2487 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2488 redundant calls to mark_vectorlike for bool vectors.
2490 2012-06-30 Glenn Morris <rgm@gnu.org>
2492 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2494 * epaths.in (PATH_SITELOADSEARCH): New.
2495 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2496 This is rather than relying on --enable-locallisppath elements
2497 having "site-lisp" in their names. (Bug#10208#25, 11658)
2499 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2501 * w32proc.c (sys_select): Accept and ignore one more argument.
2503 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2505 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2506 (pselect) [!MS_DOS]: Redirect to sys_select.
2508 * sysdep.c: Don't include dos.h and dosfns.h.
2510 * process.c (sys_select):
2511 * msdos.c (sys_select): Accept one more argument and ignore it.
2513 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2514 adapt data types and code to that.
2517 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2518 which clashes with the gnulib function of the same name.
2520 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2522 * font.c (font_style_to_value, font_style_symbolic)
2523 (font_prop_validate_style): Add type checks for values in
2526 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2528 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2531 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2533 * xdisp.c (try_window_id): Undo last change.
2535 * w32.c (getwd): Adjust commentary about startup_dir.
2536 (init_environment): Always call sys_access, even in non-MSVC
2537 builds. Don't chdir to the directory of the Emacs executable.
2538 This undoes code from 1997 which was justified by the need to
2539 "avoid conflicts when removing and renaming directories". But its
2540 downside was that every relative file name was being interpreted
2541 relative to the directory of the Emacs executable, which can never
2542 be TRT. In particular, it broke sys_access when called with
2543 relative file names.
2544 (sys_access): Map GetLastError to errno.
2546 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2548 * window.h (struct window): Change type of 'fringes_outside_margins'

2552 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2555 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2557 * gnutls.c (emacs_gnutls_handshake):
2558 Add QUIT to make the loop interruptible.
2560 2012-06-29 Glenn Morris <rgm@gnu.org>
2562 * charset.c (init_charset): Make lack of etc/charsets fatal.
2564 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2566 * editfns.c (region_limit): Fix type mismatch.
2568 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2570 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2571 undefined. Convert from xassert to eassert.
2572 * nsmenu.m: Convert from xassert to eassert.
2573 * nsterm.m: Likewise.
2575 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2577 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2579 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2581 Avoid integer overflow on scroll-left and scroll-right.
2582 * window.c (HSCROLL_MAX): New macro.
2583 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2584 overflow when requested scroll falls outside ptrdiff_t range.
2586 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2588 * window.h (struct window): Change type of 'hscroll',
2589 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2590 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2591 Adjust users accordingly.
2592 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2593 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2594 from EMACS_INT to ptrdiff_t.
2595 (make_window): Omit redundant initialization.
2597 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2601 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2603 * window.h (struct window): Change type of 'use_time' and
2604 'sequence_number' from Lisp_Object to int.

2670 * alloc.c (allocate_string): Omit intervals initialization.
2671 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2672 as in make_pure_string and make_pure_c_string.

2728 * alloc.c: Remove build_string.
2729 * lisp.h: Define build_string as static inline. This provides
2730 a better opportunity to optimize away calls to strlen when the
2731 function is called with compile-time constant argument.
2732 * image.c (imagemagick_error): Convert to build_string.
2733 * w32proc.c (sys_spawnve): Likewise.

2736 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2738 Use sprintf return value instead of invoking strlen on result.
2739 In the old days this wasn't portable, since some sprintf
2740 implementations returned char *. But they died out years ago and
2741 Emacs already assumes sprintf returns int.
2742 Similarly for float_to_string.
2743 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2744 * ccl.c (ccl_driver):
2745 * character.c (string_escape_byte8):

2750 * xfns.c (syms_of_xfns):
2751 Use sprintf or float_to_string result to avoid need to call strlen.
2752 * data.c (Fnumber_to_string):
2753 Use make_unibyte_string, since the string must be ASCII.
2754 * lisp.h, print.c (float_to_string): Now returns int length.
2755 * term.c (produce_glyphless_glyph):
2756 Use sprintf result rather than recomputing it.
2758 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2759 * Makefile.in (ALL_CFLAGS):

2857 * keyboard.c (kbd_buffer_get_event):
2858 * process.c (Faccept_process_output):
2859 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2860 This improves on the previous patch, which introduced a bug
2861 when time_t is unsigned and as wide as intmax_t.
2862 See <http://bugs.gnu.org/9000#51>.
2864 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2927 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2929 Support higher-resolution time stamps (Bug#9000).
2930 The time stamps are only nanosecond-resolution at the C level,
2931 since that's the best that any real-world system supports now.
2932 But they are picosecond-resolution at the Lisp level, as that's
2933 easy, and leaves room for future OS improvements.
2935 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2938 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2939 Don't get current time unless it's needed.
2941 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2942 now provides it if it's absent.
2943 (start_atimer): Port to higher-res time stamps.
2944 Check for time stamp overflow. Don't get current time more
2945 often than is needed.
2947 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2948 Include systime.h, not time.h.
2949 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

2955 (struct image): Timestamp now has higher resolution.
2957 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2958 has at least microseconds now. All uses removed.
2959 (update_frame, update_single_window, update_window, update_frame_1)
2960 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2962 * editfns.c (time_overflow): Now extern.
2963 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2968 (decode_time_components, lisp_seconds_argument): New functions.
2969 (make_time): Now static.
2970 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2971 Report an error if the time is invalid, rather than having the caller
2974 * fileio.c: Include <stat-time.h>
2975 (Fcopy_file): Copy higher-resolution time stamps.
2976 Prefer to set the time stamp via a file descriptor if that works.

2978 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2979 (Fvisited_file_modtime, Fset_visited_file_modtime):
2980 Support higher-resolution time stamps.
2982 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2984 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2986 * image.c (prepare_image_for_display, clear_image_cache)
2987 (lookup_image): Port to higer-resolution time stamps.
2989 * keyboard.c (start_polling, bind_polling_period):
2990 Check for time stamp overflow.
2991 (read_char, kbd_buffer_get_event, timer_start_idle)
2992 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2993 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2994 Port to higher-resolution time stamps. Do not assume time_t is signed.
2995 (decode_timer): New function. Timers are now vectors of length 9,
2996 not 8, to accommodate the picosecond component.
2997 (timer_check_2): Use it.
2999 * nsterm.m (select_timeout, timeval_subtract): Remove.
3000 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3001 as they're a bit more accurate and handle overflow better.
3002 (ns_select): Change prototype to be compatible with pselect.
3003 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3004 * nsterm.h (ns_select): Adjust prototype.
3006 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3007 us-resolution time stamps.
3008 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3010 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3012 * lisp.h (time_overflow): New decl.
3013 (wait_reading_process_output): First arg is now intmax_t, not int,
3014 to accommodate larger waits.
3016 * process.h (struct Lisp_Process.read_output_delay):
3017 Now counts nanoseconds, not microseconds.
3018 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3020 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3021 (wait_reading_process_output):
3022 Port to ns-resolution time stamps.
3023 (Faccept_process_output, wait_reading_process_output):
3024 Check for time stamp overflow. Do not assume time_t is signed.
3025 (select_wrapper): Remove; we now use pselect.
3026 (Fprocess_attributes): Now generates ns-resolution time stamps.
3028 * sysdep.c: Include utimens.h. Don't include utime.h
3029 or worry about struct utimbuf; gnulib does that for us now.
3030 (gettimeofday): Remove; gnulib provides a substitute.
3031 (make_timeval): New function.
3032 (set_file_times): Now sets ns-resolution time stamps.
3033 New arg FD; all uses changed.
3034 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3035 (system_process_attributes):
3036 Now returns ns-resolution time stamp. All uses changed.
3037 Check for time stamp overflow.
3039 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3040 provides a substitute now.
3042 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3043 since it guarantees struct timespec.
3044 (EMACS_TIME): Now struct timespec, so that we can support
3045 ns-resolution time stamps.
3046 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3047 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3048 (EMACS_USECS): Remove.
3049 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3050 so multiply the arg by 1000 before storing it.
3051 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3053 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3054 Port to ns-resolution time stamps.
3055 (EMACS_TIME_NEG_P): Remove; replaced by....
3056 (EMACS_TIME_SIGN): New macro.
3057 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3058 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3059 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3060 (make_timeval, make_lisp_time, decode_time_components): New decls.
3061 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3062 that it mishandled time_t overflow. You can't compare by subtracting!
3063 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3064 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3066 * term.c: Include <sys/time.h>.
3067 (timeval_to_Time): New function, for proper overflow wraparound.

3072 (Fprimitive_undo): Use them when restoring time stamps.
3074 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3075 (w32_get_internal_run_time):
3076 Port to higher-resolution Emacs time stamps.
3077 (ltime): Now accepts single 64-bit integer, as that's more convenient
3080 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3082 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3083 for compatibility with pselect. Support ns-resolution time stamps.
3085 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3087 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3088 Check for time stamp overflow, and support ns-resolution time stamps.
3090 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3091 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3092 (timeval_subtract): Remove; no longer needed.
3093 (XTflash, XTring_bell, x_wait_for_event):
3094 Port to ns-resolution time stamps. Don't assume time_t is signed.
3096 2012-06-22 Chong Yidong <cyd@gnu.org>

3100 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3102 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3103 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3104 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3105 staticidx goes up to 1597 out of 1600 = 0x640.)
3107 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3109 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3110 Otherwise, the umask might be mistakenly 0 while handling input signals.

3132 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3134 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3135 since tty frames can be explicitly named.
3136 (prepare_menu_bars): Likewise.
3138 * term.c (Ftty_top_frame): New function.
3140 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

3143 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3144 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3145 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3146 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3147 (METER_1, METER_2): Simplify.
3149 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3151 * data.c (Fdefalias): Return `symbol' (bug#11686).
3153 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3155 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3156 gets killed during executing of this function (Bug#11665).
3157 Try to always return Qt when the buffer has been actually killed.
3158 (Vkill_buffer_query_functions): In doc-string say that functions
3159 run by this hook should not change the current buffer.
3161 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3163 Fix recently-introduced process.c problems found by static checking.
3164 * process.c (write_queue_push, write_queue_pop, send_process):

3181 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3183 * lisp.h (eassert): Assume C89 or later.
3184 This removes the need for CHECK.
3185 (CHECK): Remove. Its comments about always evaluating its
3186 argument were confusing, as 'eassert' typically does not evaluate
3189 * coding.c (produce_chars): Use ptrdiff_t, not int.
3191 * xterm.c (x_draw_underwave): Check for integer overflow.
3192 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3376 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3377 code works fine either way, and efficiency is not a concern here,
3378 as the union type is for debugging, not for production.
3379 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3380 Use an inline function on all platforms when using the union type,
3381 since this is simpler and 'static inline' can be used portably
3383 (LISP_INITIALLY_ZERO): New macro.
3384 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

3492 * alloc.c (allocate_vectorlike): Fix last change.

3523 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3525 * doprnt.c (doprnt): Truncate multibyte char correctly.
3526 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3527 would mishandle a string argument "Xc" if X was a multibyte
3528 character of length 2: it would truncate after X's first byte
3529 rather than including all of X.
3531 2012-06-06 Chong Yidong <cyd@gnu.org>

3582 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3583 Convert pctcpu and pctmem to Lisp float properly.
3584 Let the compiler fold better, as 100.0/0x8000 is exact.

3588 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

3598 bitfields where appropriate, remove unused fields.
3599 * window.h (struct window): Remove unused 'last_mark_x' and

3603 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3604 fields from Lisp_Object to bitfield. Adjust users accordingly.

3612 and 'double' in a couple of places.
3614 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3616 * xdisp.c (handle_stop): Detect whether we have overlay strings
3617 loaded by testing it->current.overlay_string_index to be
3618 non-negative, instead of checking whether n_overlay_strings is
3619 positive. (Bug#11587)
3621 2012-05-31 Chong Yidong <cyd@gnu.org>
3623 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

3629 * search.c (search_buffer): Remove calls to
3630 r_alloc_inhibit_buffer_relocation, as it is now called by
3631 maybe_unify_char, which was the cause of relocation of buffer text
3634 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3636 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3637 for the duration of call to load_charset, to avoid problems with
3638 callers of maybe_unify_char that access buffer text through C
3641 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3642 decrement the inhibition flag, instead of just setting or
3645 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3647 Remove obsolete '#define static' cruft.
3648 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3649 This #undef was "temporary" in 2000; it is no longer needed
3650 now that '#define static' has gone away.
3651 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3652 (gray_bitmap_bits): Remove; no longer needed.
3653 All uses replaced with definiens.

3697 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3698 Bug#9642, but explicitly check that the buffer the overlay would
3699 be moved to is live and rearrange lines to make sure that errors
3700 will not put the overlay in an inconsistent state.
3701 (Fdelete_overlay): Cosmetics.
3703 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3705 * w32term.c (my_bring_window_to_top): New function.
3706 (x_raise_frame): Use handle returned by DeferWindowPos, which

3735 when referring to sectname field in printf format.
3737 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3739 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3740 Only r_alloc_inhibit_buffer_relocation needed to be added;
3741 the others were already declared.
3743 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3744 before checking whether it's out of range. Put the check inside
3746 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3748 2012-05-27 Ken Brown <kbrown@cornell.edu>
3750 * callproc.c (Fcall_process): Restore a line that was accidentally
3751 commented out in the 2011-02-13 change (bug#11547).
3753 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3755 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3756 defined on ralloc.c.
3758 * buffer.c [REL_ALLOC]: Remove prototypes of
3759 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3760 they are now on lisp.h.
3762 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3764 * search.c (search_buffer): Use it to inhibit relocation of buffer
3765 text while re_search_2 is doing its job, because re_search_2 is
3766 passed C pointers to buffer text. (Bug#11519)
3768 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3771 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3772 state after an additional call to move_it_in_display_line_to, keep
3773 the values of it->max_ascent and it->max_descent found for the
3775 (pos_visible_p): Revert the comparison against bottom_y to what it
3776 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3779 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3781 Fix coding-related core dumps with gcc -ftrapv.
3782 The code was computing A - B, where A and B are pointers, and B is
3783 random garbage. This can lead to core dumps on platforms that
3784 have special pointer registers, and it also leads to core dumps on
3785 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3786 A - B only when B is initialized properly.
3787 * coding.c (coding_set_source, coding_set_destination): Return void.
3788 (coding_change_source, coding_change_destinations): New functions,
3789 with the old behaviors of coding_set_source and coding_set_destination.

3800 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3802 * w32console.c: Include window.h.
3803 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3805 (initialize_w32_display): Initialize mouse-highlight data.
3807 * w32inevt.c: Include termchar.h and window.h.
3808 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3809 moves, call note_mouse_highlight. If help_echo changed, call
3810 gen_help_event to produce help-echo message in the echo area.
3811 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3814 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3816 * lread.c (read1): Simplify slightly to avoid an overflow warning
3817 with GCC 4.7.0 on x86-64.
3819 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3821 * bidi.c (bidi_mirror_char): Revert last change: an int is
3822 definitely wide enough here.
3824 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3826 Fix integer width and related bugs (Bug#9874).

3837 (allocate_pseudovector):
3838 Use int, not EMACS_INT, where int is wide enough.
3839 (inhibit_garbage_collection, Fgarbage_collect):
3840 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3858 (Foverlay_recenter, last_overlay_modification_hooks_used)
3859 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3860 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3861 (validate_region): Omit unnecessary test for b <= e,
3862 since that's guaranteed by the previous test.
3863 (adjust_overlays_for_delete): Avoid pos + length overflow.
3864 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3865 (report_overlay_modification):
3866 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3867 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3869 after the EMACS_INT -> ptrdiff_t change.

3876 not int, to avoid needless 32-bit limit on 64-bit hosts.
3877 (exec_byte_code): Use tighter memory-full test, one that checks
3878 for alloca overflow. Don't compute the address of the object just
3879 before an array, as that's not portable. Use EMACS_INT, not
3880 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3881 * callint.c (Fcall_interactively):
3882 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3894 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3895 (casify_object): Avoid integer overflow when overallocating buffer.
3896 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3897 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3898 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3899 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3900 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3901 integers are now checked earlier. All uses replaced with XINT.
3903 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3904 For CCL_MapSingle, check that content and value are in int range.
3905 (ccl_driver, Fregister_code_conversion_map):
3906 Check that Vcode_version_map_vector is a vector.
3907 (resolve_symbol_ccl_program): Check that vector header is in range.
3908 Always copy the vector, so that we can check its contents reliably
3909 now rather than having to recheck each instruction as it's being
3910 executed. Check that vector words fit in 'int'.
3911 (ccl_get_compiled_code, Fregister_ccl_program)
3912 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3913 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3914 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3915 contents are in range.
3916 (Fccl_execute_on_string): Check that status is in range.
3917 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3918 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3919 Accept and return EMACS_INT, not int, because callers can pass values
3921 (c_string_width, strwidth, lisp_string_width, chars_in_text)

3925 (string_escape_byte8, Fget_byte):
3926 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3927 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3928 avoid mishandling large integers.
3929 * character.h: Adjust decls to match defn changes elsewhere.

3938 (Fdefine_charset_internal): Check ranges here, more carefully.
3939 Don't rely on undefined behavior with signed left shift overflow.
3940 Don't assume unsigned int fits into fixnum, or that fixnum fits
3941 into unsigned int. Don't require max_code to be a valid fixnum;
3942 that's not true for gb10830 4-byte on a 32-bit host. Allow
3943 invalid_code to be a cons, for the same reason. Require code_offset
3944 to be a character. Avoid int overflow if max_char is close
3946 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3947 this is intended anyway and avoids some undefined behavior.
3948 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3949 INDEX_TO_CODE_POINT, as that's what it expects.
3950 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3951 * charset.h (DECODE_CHAR): Return int, not unsigned;
3952 this is what was intended anyway, and it avoids undefined behavior.
3953 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3954 integer-overflow issues.
3955 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3956 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3957 where the argument is EMACS_INT, and this behavior is not intended.
3958 * chartab.c (Fmake_char_table, Fset_char_table_range)
3959 (uniprop_get_decoder, uniprop_get_encoder):
3960 Don't assume fixnum fits in int.
3961 * cmds.c (move_point): New function, that does the gist of
3962 Fforward_char and Fbackward_char, but does so while checking
3963 for integer overflow more accurately.
3964 (Fforward_char, Fbackward_char): Use it.
3965 (Fforward_line, Fend_of_line, internal_self_insert)
3966 (internal_self_insert):
3967 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4678 Move here from removed file m/intel386.h.
4679 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.

4766 already have overlays loaded.
4767 (handle_single_display_spec): Before returning without displaying
4768 fringe bitmap, synchronize the bidi iterator with the main display
4769 iterator, by calling iterate_out_of_display_property.
4770 (iterate_out_of_display_property): Detect buffer iteration by
4771 testing that it->string is a Lisp string.
4772 (get_next_display_element): When the current object is exhausted,
4773 and there's something on it->stack, call set_iterator_to_next to
4774 proceed with what's on the stack, instead of returning zero.
4775 (set_iterator_to_next): If called at the end of a Lisp string,
4776 proceed to consider_string_end without incrementing string
4777 position. Don't increment display vector index past the end of
4778 the display vector. (Bug#11417)
4779 (pos_visible_p): Don't report a position visible when move_it_to
4780 stopped at the last line of window, which happens to be scanned
4781 backwards by the bidi iteration. (Bug#11464)
4783 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4785 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4786 and right-margin display specs even if the spec is invalid or we
4787 are on a TTY, and thus unable to display on the fringes.
4788 That's because the text with the property will not be displayed anyway,
4789 so we need to signal to the caller that this is a "replacing"
4790 display spec. This fixes display when the spec is invalid or we
4793 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4795 * unexaix.c (make_hdr): Fix typo in prototype.
4796 This bug broke the build on AIX. Problem reported by Gilles Pion.

4828 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4830 * xgselect.c (xg_select): Put maxfds+1 into a var.
4831 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4833 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4835 2012-05-10 Dave Abrahams <dave@boostpro.com>

4849 Untag more efficiently if USE_LSB_TAG.
4850 This is based on a proposal by YAMAMOTO Mitsuharu in
4851 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4852 For an admittedly artificial (nth 8000 longlist) benchmark on
4853 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4854 Emacs's overall text size by 1%.
4855 * lisp.h (XUNTAG): New macro.
4856 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)

4858 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4859 * eval.c (Fautoload):
4860 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4861 * frame.h (XFRAME): Use XUNTAG.
4863 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4864 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4865 Remove unportable assumptions about print widths of types like
4867 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4868 intptr_t when converting between pointer and integer, to avoid GCC
4869 warnings about wrong width.
4871 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4873 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4874 stack for each reader_thread, instead of defaulting to 8MB
4875 determined by the linker. This avoids failures in creating
4876 subprocesses on Windows 7, see the discussion in this thread:
4877 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4879 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4881 Fix up display of the *Minibuf-0* buffer in the mini window.
4882 * keyboard.c (read_char): Don't clear the echo area if there's no
4884 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4885 contents of *Minibuf-0*) if there's no message displayed in its stead.
4887 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4889 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4892 2012-05-06 Chong Yidong <cyd@gnu.org>
4894 * lisp.mk (lisp): Update.
4896 2012-05-05 Jim Meyering <meyering@redhat.com>
4898 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4900 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4902 * data.c (PUT_ERROR): New macro.
4903 (syms_of_data): Use it. Add new error type `user-error'.
4904 * undo.c (user_error): New function.
4905 (Fprimitive_undo): Use it.
4906 * print.c (print_error_message): Adjust print style for `user-error'.
4907 * keyboard.c (user_error): New function.
4908 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4910 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4912 Do not limit current-time-string to years 1000..9999.
4913 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4914 (Fcurrent_time_string): Support any year that is supported by the
4915 underlying localtime representation. Don't use asctime, as it
4916 has undefined behavior for years outside the range -999..9999.
4918 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4920 Fix race conditions involving setenv, gmtime, localtime, asctime.
4921 Without this fix, interrupts could mess up code that uses these
4922 nonreentrant functions, since setting TZ invalidates existing
4923 tm_zone or tzname values, and since most of these functions return
4924 pointers to static storage.
4925 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4926 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4927 Grow the critical sections to include not just invoking
4928 localtime/gmtime, but also accessing these functions' results
4929 including their tm_zone values if any, and any related TZ setting.
4930 (format_time_string): Last arg is now struct tm *, not struct tm **,
4931 so that the struct tm is saved in the critical section.
4932 All callers changed. Simplify allocation of initial buffer, partly
4933 motivated by the fact that memory allocation needs to be outside
4934 the critical section.
4936 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4938 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4939 with RESET_INTERVAL.
4941 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4942 Remove duplicated buffer name initialization.
4944 2012-05-02 Jim Meyering <jim@meyering.net>
4946 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4948 * xfns.c (x_window): Use xstrdup (Bug#11375).
4950 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4952 * xdisp.c (pos_visible_p): If already at a newline from the
4953 display string before the 'while' loop, don't walk back the glyphs
4954 from it3.glyph_row. Solves assertion violation when the display
4955 string begins with a newline (egg.el). (Bug#11367)
4957 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4959 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4962 2012-05-01 Glenn Morris <rgm@gnu.org>
4964 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4965 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4966 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4967 All were removed before 23.1.
4969 * dispnew.c: Remove HAVE_LIBNCURSES test;
4970 it is always true on relevant platforms.
4972 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4973 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4975 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4977 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4979 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4980 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4983 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4985 Do not avoid creating empty evaporating overlays (Bug#9642).
4986 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4987 That is, do not delete an evaporating overlay if it becomes
4988 empty after its bounds are adjusted to fit within its buffer.
4989 This fix caused other problems, and I'm reverting it until we get
4990 to the bottom of them.
4992 2012-04-27 Chong Yidong <cyd@gnu.org>
4994 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4996 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4998 * xdisp.c (pos_visible_p): If the window start position is beyond
4999 ZV, start the display from buffer beginning. Prevents assertion
5000 violation in init_iterator when the minibuffer window is scrolled
5003 * window.c (window_scroll_pixel_based): Likewise.
5005 2012-04-27 Chong Yidong <cyd@gnu.org>
5007 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5009 2012-04-27 Glenn Morris <rgm@gnu.org>
5011 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5012 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5014 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5016 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5017 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5019 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5021 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5022 display element, check also the underlying string or buffer
5023 character. (Bug#11341)
5025 * w32menu.c: Include w32heap.h.
5026 (add_menu_item): If the call to AppendMenuW (via
5027 unicode_append_menu) fails, disable Unicode menus only if we are
5028 running on Windows 9X/Me.
5030 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5032 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5033 (xgetint): Add missing shift for LSB tags.
5035 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5037 * keyboard.c (read_char): Don't wipe echo area for select window
5038 events: These might get delayed via `mouse-autoselect-window'
5041 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5043 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5044 manipulation of :loaded-from data.
5046 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5048 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5049 now a cons (bug#11311).
5051 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5053 Do not create empty overlays with the evaporate property (Bug#9642).
5054 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5055 if it becomes empty after its bounds are adjusted to fit within
5056 its buffer. Without this fix, in a nonempty buffer (let ((o
5057 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5058 yields an empty overlay that has the evaporate property, which is
5059 not supposed to happen.
5061 Fix minor GTK3 problems found by static checking.
5062 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5063 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5064 (struct _EmacsFixedClass, emacs_fixed_get_type):

5077 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5079 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5081 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5082 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5083 (__malloc_size_t, __malloc_ptrdiff_t):
5084 Remove. All uses removed, replaced by the definiens if needed,
5085 since we can assume C89 or better now.
5086 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5087 (protect_malloc_state, align, get_contiguous_space)

5094 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5095 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5096 Define using prototypes, not old style.
5097 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5098 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5099 (align): Don't assume that signed integer overflow wraps around.
5100 Omit unused local var.
5101 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

5278 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5279 [REL_ALLOC]: ... to here, to check interface.
5280 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5281 Remove decls. This fixes an "It stinks!".
5283 * alloc.c (which_symbols): Fix alignment issue / type clash.
5285 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5287 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5304 Remove definition of GC_MARK_STACK, since the default now works.
5305 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5306 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5307 no longer the default.
5308 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5310 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5312 * lread.c (lisp_file_lexically_bound_p):
5313 Fix hang at ";-*-\n" (bug#11238).
5315 2012-04-14 Eli Zaretskii <eliz@gnu.org>
5317 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
5318 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
5320 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5322 * nsterm.m (constrainFrameRect): Always constrain when there is only
5323 one screen (Bug#10962).
5325 2012-04-13 Ken Brown <kbrown@cornell.edu>
5327 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

5333 2012-04-11 Daniel Colascione <dancol@dancol.org>
5335 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5336 against is gone. It's better to use vfork now so that when Cygwin
5337 gains a new, working vfork, we use it automatically (bug#10398).
5339 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5341 * window.c (save_window_save): Obey window-point-insertion-type.

5345 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
5347 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5349 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
5351 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5353 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5354 (force_quit_count): New var.
5355 (handle_interrupt): Use it.
5357 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5359 * w32.c (w32_delayed_load): Record the full path of the library
5360 being loaded (bug#10424).
5362 2012-04-09 Glenn Morris <rgm@gnu.org>
5364 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5365 not just in the obarray, before snarfing them. (Bug#11036)
5367 * Makefile.in ($(leimdir)/leim-list.el):
5368 Pass EMACS rather than BUILT_EMACS.
5370 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5372 * process.c (make_process):
5373 * process.h: Add integer `gnutls_handshakes_tried' member to
5376 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5377 Add convenience `GNUTLS_LOG2i' macro.
5379 * gnutls.c (gnutls_log_function2i): Convenience log function.
5380 (emacs_gnutls_read): Use new log functions,
5381 `gnutls_handshakes_tried' process member, and
5382 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5383 attempts per process (connection).
5385 2012-04-09 Chong Yidong <cyd@gnu.org>
5387 * eval.c (Fuser_variable_p, user_variable_p_eh)
5388 (lisp_indirect_variable): Functions deleted.
5389 (Fdefvar): Caller changed.
5391 * callint.c (Finteractive, Fcall_interactively):
5392 * minibuf.c (Fread_variable): Callers changed.
5394 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5396 * xdisp.c (set_cursor_from_row): If the display string appears in
5397 the buffer at position that is closer to point than the position
5398 after the display string, display the cursor on the first glyph of
5399 the display string. Fixes cursor display when a 'display' text
5400 property immediately follows invisible text. (Bug#11094)
5402 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5404 composite.c: use 'double' consistently
5405 * composite.c (get_composition_id): Use 'double' consistently
5406 instead of converting 'float' to 'double' and vice versa; this is
5407 easier to understand and avoids a GCC warning.
5409 2012-04-09 Glenn Morris <rgm@gnu.org>
5411 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5412 preparation for dumping it with emacs. (Bug#4789)
5413 (leimdir): New variable.
5414 ($(leimdir)/leim-list.el): New rule.
5415 (emacs$(EXEEXT)): Depend on leim-list.el.
5417 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
5418 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
5419 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
5421 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5423 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5426 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5428 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5429 Remove unused local variable.
5431 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5433 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5434 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5435 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5436 objects, as mark_maybe_pointer will catch them otherwise.
5437 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5438 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5440 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5442 Fix typo that broke non-Windows builds.
5443 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5445 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5447 Support building on MS-Windows with libxml2.
5449 * makefile.w32-in (OBJ2): Add xml.$(O).
5450 (GLOBAL_SOURCES): Add xml.c.
5451 ($(BLD)/xml.$(O)): New dependency list.
5453 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5454 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5455 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5456 [!WINDOWSNT]: New macros.
5457 (init_libxml2_functions, libxml2_loaded_p): New functions.
5458 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5459 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5460 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5461 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5463 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5464 Call init_libxml2_functions before calling libxml2 functions.
5465 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5467 * emacs.c: Don't include libxml/parser.h.
5468 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5469 xmlCleanupParser directly.
5471 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5473 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5475 * indent.c (Fvertical_motion): If there is a display string at
5476 point, use it.vpos to compute how many lines to backtrack after
5477 move_it_to point. (Bug#11133)
5479 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5481 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5482 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5483 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5484 macros related to unification of CJK characters. For the details,
5485 see the discussion following the message here:
5486 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5488 2012-04-04 Chong Yidong <cyd@gnu.org>
5490 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5492 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5494 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5495 instead of alloca. (Bug#11138)
5497 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5499 * w32menu.c (is_simple_dialog): Properly check lisp types.
5502 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5504 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5505 position we get to after a call to move_it_to fails the
5506 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5507 only if we wind up in a string from display property. (Bug#11063)
5509 * window.c (Fdelete_other_windows_internal): Invalidate the row
5510 and column information about mouse highlight, so that redisplay
5511 restores it after reallocating the glyph matrices. (Bug#7464)
5513 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5514 string comes from a `display' text property, use the buffer
5515 position of that property as if we actually saw that position in
5517 (move_it_by_lines): Remove the assertion that
5518 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5519 violated when there's a before-string at the beginning of a line.
5522 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5524 * xdisp.c (append_space_for_newline): If the default face was
5525 remapped, use the remapped face for the appended newline.
5526 (extend_face_to_end_of_line): Use the remapped default face for
5527 extending the face to the end of the line.
5528 (display_line): Call extend_face_to_end_of_line when the default
5529 face was remapped. (Bug#11068)
5531 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5533 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5535 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5537 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5539 2012-03-27 Glenn Morris <rgm@gnu.org>
5541 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5544 2012-03-26 Kenichi Handa <handa@m17n.org>
5546 * dispextern.h (struct glyph): Fix previous change. Change the
5547 bit length of glyphless.ch to 25 (Bug#11082).
5549 2012-03-26 Chong Yidong <cyd@gnu.org>
5551 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5552 (command_loop_1): Use it; inhibit selection update for
5553 handle-select-window too (Bug#8996).
5555 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5557 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5559 2012-03-25 Kenichi Handa <handa@m17n.org>
5561 * dispextern.h (struct glyph): Change the bit length of
5562 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5564 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5566 * s/ms-w32.h (tzname): Include time.h before redirecting to
5567 _tzname. Fixes the MSVC build. (Bug#9960)
5569 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5571 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5574 * xterm.c (XTread_socket): Only modify handling_signal if
5575 !SYNC_INPUT. (Bug#11080)
5577 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5579 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5580 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5581 when fetching a multibyte character consumes more bytes than
5582 CHAR_BYTES returns, due to unification of CJK characters in
5583 string_char. (Bug#11073)
5585 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5587 * process.c (wait_reading_process_output): Handle pty disconnect
5588 by refraining from sending oneself a SIGCHLD (bug#10933).
5590 2012-03-22 Chong Yidong <cyd@gnu.org>
5592 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5594 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5595 Mark string as coming from a prefix property.
5596 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5597 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5599 2012-03-21 Chong Yidong <cyd@gnu.org>
5601 * xfaces.c (Vface_remapping_alist): Doc fix.
5603 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5605 * w32proc.c (Fw32_set_console_codepage)
5606 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5609 2012-03-20 Chong Yidong <cyd@gnu.org>
5611 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5612 to reflect default non-nil value of redisplay-dont-pause.
5614 2012-03-19 Kenichi Handa <handa@m17n.org>
5616 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5617 it fit in a valid range (Bug#11003).
5619 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5621 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5622 that is not from display property, accept the row as a "cursor
5623 row" if one of the string's character has a non-nil `cursor'
5624 property. Fixes cursor positioning when there are newlines in
5625 overlay strings, e.g. in icomplete.el. (Bug#11035)
5627 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5629 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5631 2012-03-12 Chong Yidong <cyd@gnu.org>
5633 * eval.c (inhibit_lisp_code): Rename from
5634 inhibit_window_configuration_change_hook; move from window.c.
5636 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5637 * window.c (run_window_configuration_change_hook)
5638 (syms_of_window): Callers changed.
5640 2012-03-11 Chong Yidong <cyd@gnu.org>
5642 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5644 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5646 2012-03-10 Chong Yidong <cyd@gnu.org>
5648 * frame.c (other_visible_frames): Don't assume the selected frame
5649 is visible (Bug#10955).
5651 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5653 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5655 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5657 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5658 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5661 2012-03-03 Glenn Morris <rgm@gnu.org>
5663 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5665 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5667 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5668 position past the first glyph_row that ends at ZV. (Bug#10902)
5669 (redisplay_window, next_element_from_string): Fix typos in
5671 (redisplay_window): Pass to move_it_vertically the margin in
5672 pixels, not in screen lines.
5674 2012-03-02 Glenn Morris <rgm@gnu.org>
5676 * buffer.c (buffer-list-update-hook): Doc fix.
5678 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5680 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5681 push_it before setting up the iterator for the first overlay
5682 string, even if we have an empty string loaded.
5683 (next_overlay_string): If there's an empty string on the iterator
5684 stack, pop the stack. (Bug#10903)
5686 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5688 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5689 Suggested by Stefan Monnier in
5690 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5691 * alloc.c (widen_to_Lisp_Object): New static function.
5692 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5693 and widening them to Lisp_Objects. This would work even if
5694 USE_LSB_TAG is defined and wide integers are used, which might
5695 happen in a future version of Emacs.
5697 2012-02-25 Chong Yidong <cyd@gnu.org>
5699 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5702 * xselect.c (Fx_selection_exists_p): Doc fix.
5703 (x_clipboard_manager_save_all): Print an informative message
5704 before saving to clipboard manager.
5706 2012-02-24 Chong Yidong <cyd@gnu.org>
5708 * keyboard.c (process_special_events): Handle all X selection
5709 requests in kbd_buffer, not just the next one (Bug#8869).
5711 2012-02-23 Chong Yidong <cyd@gnu.org>
5713 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5714 call when setting menu-bar-lines and tool-bar-lines parameters.
5715 (unwind_create_frame_1): New helper function.
5717 * window.c (inhibit_window_configuration_change_hook): New var.
5718 (run_window_configuration_change_hook): Obey it.
5719 (syms_of_window): Initialize it.
5721 2012-02-22 Chong Yidong <cyd@gnu.org>
5723 * xterm.c (x_draw_image_relief): Add missing type check for
5724 Vtool_bar_button_margin (Bug#10743).
5726 2012-02-21 Chong Yidong <cyd@gnu.org>
5728 * fileio.c (Vfile_name_handler_alist): Doc fix.
5730 * buffer.c (Fget_file_buffer): Protect against invalid file
5731 handler return value.
5733 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5735 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5736 when computing $valmask.
5738 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5739 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5740 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5741 It's useless in that case, and it can cause problems on hosts
5742 that allocate halves of EMACS_INT values separately.
5743 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5744 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5745 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5746 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5747 it avoids undefined behavior on hosts where shifting right by more
5748 than the word width has undefined behavior.
5750 2012-02-19 Chong Yidong <cyd@gnu.org>
5752 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5753 (Funhandled_file_name_directory, Ffile_name_as_directory)
5754 (Fdirectory_file_name, Fexpand_file_name)
5755 (Fsubstitute_in_file_name): Protect against invalid file handler
5756 return values (Bug#10845).
5758 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5760 * .gdbinit (pitx): Fix incorrect references to fields of the
5763 2012-02-17 Chong Yidong <cyd@gnu.org>
5765 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5767 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5769 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5770 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5772 2012-02-15 Chong Yidong <cyd@gnu.org>
5774 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5775 marked as special. Also, starting docstrings with * is obsolete.
5777 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5779 * gnutls.c (emacs_gnutls_write): Fix last change.
5781 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
5783 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
5786 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5788 * keymap.c (Fsingle_key_description): Handle char ranges.
5790 2012-02-12 Chong Yidong <cyd@gnu.org>
5792 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5793 as that creates a dangerous corner case.
5795 * window.c (Fdelete_window_internal): Invalidate the mouse
5796 highlight (Bug#9904).
5798 2012-02-12 Glenn Morris <rgm@gnu.org>

6353 * fileio.c (Finsert_file_contents): Move after-change-function call
6354 to before the "handled:" label, since all "goto handled" appear in

6531 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6532 is set, removing the need for VIRT_ADDRESS_VARIES.
6533 (PURE_P): Use a more-efficient implementation that needs just one
6534 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6535 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6536 to 4 (xorl, subq, cmpq, setbe).
6537 * alloc.c (pure): Always extern now, since that's the
6538 VIRT_ADDR_VARIES behavior.
6539 (PURE_POINTER_P): Use a single comparison, not two, for
6540 consistency with the new puresize.h.
6541 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6550 behave as if the cursor position were at the window margin.
6552 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6553 and the cursor position is out of bounds, behave as if the cursor
6554 position were at the window margin. (Bug#10075)

6580 compute_line_metrics.
6581 (compute_line_metrics): Call row_hash, instead of computing the
6584 * dispnew.c (verify_row_hash): Call row_hash for computing the
6585 hash code of a row, instead of duplicating code from xdisp.c.
6587 * dispextern.h (row_hash): Add prototype.
6589 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6591 * frame.c (delete_frame): Don't delete the terminal when the last

6623 * image.c (imagemagick_load_image): Fix typo.
6625 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6627 * xdisp.c (display_line): Move the call to
6628 highlight_trailing_whitespace before the call to
6629 compute_line_metrics, since the latter needs to see the final
6630 faces of all the glyphs to compute ROW's hash value.

6778 (adjust_intervals_for_deletion): Now extern, because otherwise the
6779 extern inline functions 'offset_intervals' couldn't refer to it.
6780 (static_offset_intervals): Remove.
6781 (offset_intervals): Rewrite using the old contents of
6782 static_offset_intervals. The old version didn't conform to C99
6783 because an extern inline function contained a reference to an
6784 identifier with static linkage.
6786 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6788 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6796 return Qleft_to_right.

6805 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6806 (Fwindow_vscroll): Doc fix.
6807 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6808 argument, since it makes no sense to pass a live window and for
6809 consistency with window-child.
6811 2011-11-05 Christoph Scholtes <cschol2112@googlemail.com>

6836 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
6837 (unwind_create_frame): New function (Bug#9943).
6838 (Fx_create_frame): Restructure code to be more similar to the one in
6839 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6840 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6841 Move terminal->reference_count++ just before making the frame official

6849 Move terminal->reference_count++ just before making the frame
6850 official. Move initialization of image_cache_refcount and
6851 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

6890 * xdisp.c (note_mouse_highlight): If either of
6891 previous/next-single-property-change returns nil, treat that as
6892 the beginning or the end of the buffer. (Bug#9955)
6894 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6896 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
6897 label is not null (Bug#9951).

6901 2011-11-04 Eli Zaretskii <eliz@gnu.org>
6903 * window.c (Fwindow_body_size): Mention in the doc string that the

6919 (mouse_face_from_buffer_pos, note_mouse_highlight):
6920 Rename cover_string to disp_string.
6922 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6924 * window.c (temp_output_buffer_show): Don't use
6925 Vtemp_buffer_show_specifiers.

6953 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6955 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6956 so that this new function doesn't get optimized away by a
6957 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6959 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6961 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6963 2011-10-29 Eli Zaretskii <eliz@gnu.org>

6981 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6982 Not clear what it was for, and it causes various bugs. (Bug#9839)
6984 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6986 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6987 possible random value that matches one of those tested as
6988 condition to clear the mouse face.
6990 2011-10-28 Chong Yidong <cyd@gnu.org>
6992 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

7016 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
7017 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7019 (w32font_open_internal, compute_metrics):
7020 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7021 instead of calling the "wide" APIs directly.
7023 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
7025 * w32.h (syms_of_w32font): Add prototype.

7036 * process.c (make_process): Set gnutls_state to NULL.
7038 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7039 non-NULL, regardless of GNUTLS_INITSTAGE.
7040 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7041 an error. Set process slots as soon as we allocate them.

7063 * w32fns.c (w32_default_color_map): New function,
7064 extracted from Fw32_default_color_map.
7065 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
7067 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
7069 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
7071 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
7073 * keyboard.c (test_undefined): New function (bug#9751).
7074 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7076 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7078 * sysdep.c (init_sys_modes): Fix the check for the controlling
7079 terminal (Bug#6649).
7081 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7083 * dispextern.h (struct bidi_it): New member next_en_type.
7085 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7086 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7087 current character, check also for next_en_type being WEAK_EN.
7088 (bidi_resolve_weak): Don't enter the expensive loop if the current
7089 position is before next_en_pos. Record the bidi type of the first
7090 non-ET, non-BN character we find, in addition to its position.
7091 (bidi_level_of_next_char): Invalidate next_en_type when
7092 next_en_pos is over-stepped.
7094 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7096 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7097 * editfns.c: Rewrite current-time-zone so that it invokes
7098 the equivalent of (format-time-string "%Z") to get the time zone name.
7099 This fixes a bug when the time zone name contains characters that
7100 need converting from the system time locale to Emacs internal format.
7101 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7102 that patch fixed format-time-string to do the conversion, but
7103 I forgot to fix current-time-zone.
7104 (format_time_string): New function, containing most of
7105 what Fformat_time_string used to contain.
7106 (Fformat_time_string): Rewrite in terms of format_time_string.
7107 This doesn't change this function's behavior.
7108 (current-time-zone): Rewrite to use format_time_string.
7109 This fixes the bug reported by Michael Schierl in
7110 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7111 Jason Rumney's 2007-06-07 change worked around this bug, but
7113 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7115 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7117 * xdisp.c (start_display): If the character at POS is displayed
7118 via a display vector, reset IT->current.dpvec_index to zero.
7119 (try_window_reusing_current_matrix): If a line ends in a display
7120 vector or the next line starts in a display vector, continue
7121 redrawing the window even though the character position of
7122 start_row was reached.
7125 2011-10-18 Chong Yidong <cyd@gnu.org>
7127 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7128 with nobreak-char-display too.
7130 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7132 Fix part 3 of bug#9771.
7133 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7134 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7135 non-neutral characters if the current character is a paragraph
7136 separator (a.k.a. Newline). This avoids running the same
7137 expensive loop twice, once when we consume the preceding newline
7138 and the other time when the line actually needs to be displayed.
7139 Avoid the loop when we see neutrals on the base embedding level
7140 following a character whose directionality is the same as the
7141 paragraph's. This avoids running the expensive loop when a line
7142 ends in a long sequence of neutrals, like control characters.
7143 Add assertion against STRONG_AL type. Slightly rearrange code
7144 that determines the type of a neutral given the first non-neutral
7146 (bidi_level_of_next_char): Set next_en_pos to zero when
7147 invalidating its info.
7149 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7151 * xdisp.c (push_display_prop): Determine whether to record string
7152 or buffer position by IT->string, not by IT->method. Allow
7153 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7154 (move_it_vertically_backward): Don't look for character position
7155 immediately after the newline when in a continuation line.
7158 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7160 * window.c (coordinates_in_window): Rewrite and delabelize
7161 vertical border check. (Bug#5357) (Bug#9618)
7163 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7165 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7166 errors in XSetWindowBorder (bug#9310).
7168 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7170 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7171 avoid crash when xmalloc overrun checking is enabled.
7173 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7175 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7176 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7177 cursor motion with <left> and <right> arrow keys.
7179 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7180 some callers set that themselves.
7182 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7184 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7185 display string and the previous row comes from the same string and
7186 is empty. (Bug#9739) (Bug#9738)
7188 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7190 * doc.c (get_doc_string): Encode file name (bug#9735).
7192 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7194 * bidi.c (bidi_level_of_next_char):
7195 * xdisp.c (get_visually_first_element): Remove old incorrect
7196 comments regarding the Unicode Line Separator character.
7198 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7200 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7202 * alloc.c (Fgc_status): Do not access beyond zombies array
7203 boundary if nzombies > MAX_ZOMBIES.
7204 * alloc.c (dump_zombies): Add missing format specifier.
7206 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7208 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7209 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7211 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7212 Some packages use them to denote characters with modifiers.
7214 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7216 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7217 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7218 matching a pp-number. Rename parameter var to var1.
7220 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7222 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7224 2011-10-08 Glenn Morris <rgm@gnu.org>
7226 * callint.c (Fcall_interactively): Give a more explicit error for the
7227 'c' case with a non-character input. (Bug#8479)
7229 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7231 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7233 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7234 lines that are hscrolled on the left.
7236 * dispnew.c (buffer_posn_from_coords): Account for a possible
7237 presence of header-line. (Bug#4426)
7239 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7241 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7242 Don't advertise functionality which we discourage or doesn't work.
7244 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7246 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7247 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7248 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7249 this makes Emacs dump core during garbage collection on rare
7250 occasions. sizeof is obviously inferior to offsetof here, so
7251 stick with offsetof.
7252 (GC_POINTER_ALIGNMENT): New macro.
7253 (mark_memory): Omit 3rd (offset) arg; caller changed.
7254 Don't assume EMACS_INT alignment is the same as pointer alignment.
7256 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7258 * keyboard.c (read_key_sequence_remapped): New var.
7259 (read_key_sequence): Compute remapping in the right buffer.
7260 (command_loop_1): Use read_key_sequence's remapping directly.
7262 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7264 * dired.c (file_name_completion): Don't expand file name.
7265 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7266 before checking file name handler.
7268 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7269 they've been requested explicitly (bug#9591).
7271 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7273 * keymap.c (Fsingle_key_description): Use make_specified_string
7274 instead of build_string to build string from push_key_description.
7277 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7279 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7280 This fixes a Y2038 bug on 64-bit hosts.
7281 * buffer.c (reset_buffer):
7282 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7283 (Fclear_buffer_auto_save_failure):
7284 Use 0, not -1, to represent an unset failure time, since time_t
7285 might not be signed.
7287 Remove dependency on glibc malloc internals.
7288 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7289 Move back here from lisp.h, but with their new implementations.
7290 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7291 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7292 * charset.c (charset_table_init): New static var.
7293 (syms_of_charset): Use it instead of xmalloc. This removes a
7294 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7295 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7296 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7297 Move back to alloc.c.
7298 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7299 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7301 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7303 * nsterm.m (windowDidResize): Call x_set_window_size only when
7304 ns_in_resize is true. Otherwise set pixelwidth/height and
7305 call change_frame_size (Bug#9628).
7307 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7309 Port --enable-checking=all to Fedora 14 x86-64.
7310 * charset.c (syms_of_charset): Also account for glibc malloc's
7311 internal overhead when calculating the initial malloc maximum.
7313 Port --enable-checking=all to Fedora 14 x86.
7314 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7316 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7317 (overrun_check_realloc, overrun_check_free):
7318 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7319 That way, xmalloc returns a properly-aligned pointer even if
7320 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7321 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7322 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7323 into account when calculating the initial malloc maximum.
7324 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7325 Move here from alloc.c, so that charset.c can use it too.
7326 Properly align; the old code wasn't right for common 32-bit hosts
7327 when configured with --enable-checking=all.
7328 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7329 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7331 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7333 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7336 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7338 * xdisp.c (compute_display_string_end): If there's no display
7339 string at CHARPOS, return -1.
7341 * bidi.c (bidi_fetch_char): When compute_display_string_end
7342 returns a negative value, treat the character as a normal
7343 character not covered by a display string. (Bug#9624)
7345 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7347 * lread.c (Fread_from_string): Fix typo in docstring.
7349 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7351 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7352 newline, reseat the iterator instead of bidi-iterating there one
7353 character at a time. (Bug#9610)
7354 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7355 TO_CHARPOS if the bidi iterator is at base embedding level.
7357 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7359 * lread.c (readevalloop): Use correct code for NBSP.
7360 (read1): Likewise. (Bug#9608)
7362 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7364 * dbusbind.c (Fdbus_register_signal): When service is not
7365 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7367 2011-09-25 Glenn Morris <rgm@gnu.org>
7369 * buffer.c (truncate-lines): Doc fix.
7371 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7373 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7374 (Fset_window_next_buffers): Doc fix.
7376 2011-09-24 Glenn Morris <rgm@gnu.org>
7378 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7380 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7382 Fix minor problems found by static checking.
7383 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7384 * indent.c (Fvertical_motion): Fix == vs = typo.
7386 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7388 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7389 Default value is now t. Doc fix.
7391 * indent.c (Fvertical_motion): Compute and apply the overshoot
7392 logic when moving up, not only when moving down. Fix the
7393 confusing name and values of the it_overshoot_expected variable;
7394 logic changes accordingly. (Bug#9254) (Bug#9549)
7396 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7397 CHARPOS is covered by a display string which includes newlines.
7398 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7399 is covered by a display string with embedded newlines.
7401 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7403 * dbusbind.c (Fdbus_register_signal): Add match rule to
7404 Vdbus_registered_objects_table. (Bug#9581)
7405 (Fdbus_register_method, Vdbus_registered_objects_table):
7408 2011-09-24 Jim Meyering <meyering@redhat.com>
7410 do not ignore write error for any output size
7411 The previous change was incomplete.
7412 While it makes emacs --batch detect the vast majority of stdout
7413 write failures, errors were still ignored whenever the output size is
7414 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7415 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7416 && echo FAIL: ignored write error
7417 FAIL: ignored write error
7418 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7419 && echo FAIL: ignored write error
7420 FAIL: ignored write error
7421 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7423 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7425 * emacs.c (Fkill_emacs): In noninteractive mode exit
7426 non-successfully if a write error occurred on stdout. (Bug#9574)
7428 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7430 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7433 * dispextern.h (struct it): Update the comment documenting what
7436 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7438 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7439 a display string, extend search for cursor position to end of row.
7440 (find_row_edges): If the row ends in a newline from a display
7441 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7442 Handle the case of a display string with multiple newlines.
7443 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7444 non-empty line. Fixes confusing cursor motion with arrow keys at
7445 the beginning of a line that starts with whitespace.
7447 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7449 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7452 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7454 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7457 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7459 * xdisp.c (display_line): Record maximum and minimum buffer
7460 positions even if no glyphs were produced (e.g., by a zero-width
7461 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7462 buffer positions that will be removed from the glyph row because
7464 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7465 column is beyond frame width: don't subtract 1 "pixel" when
7466 computing width of the stretch.
7467 (reseat_at_next_visible_line_start): Undo the change made on
7468 2011-09-17 that saved paragraph information and restored it after
7469 the call to `reseat'. (Bug#9545)
7471 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7473 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7474 and turn window cursor on if cleared (Bug#9415).
7476 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7478 * search.c (boyer_moore): Take unibyte characters from pattern
7479 literally. (Bug#9458)
7481 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7483 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7485 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7487 Fix minor problem found by static checking.
7488 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7489 initialized, to pacify gcc -Wuninitialized.
7491 * fileio.c: Report proper errno when syscall falls.
7492 (Finsert_file_contents): Save and restore errno,
7493 so that report_file_error outputs the correct diagnostic.
7494 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7496 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7498 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7500 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7502 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7503 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7505 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7507 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7508 about the current paragraph and restore it after the call to reseat.
7510 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7511 (bidi_find_paragraph_start): Search back for paragraph beginning
7512 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7513 (bidi_move_to_visually_next): Only trigger paragraph-related
7514 computations when the last character is a newline or at EOB, not
7515 just any NEUTRAL_B. (Bug#9470)
7517 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7518 truncated lines if point is covered by a display string. (Bug#9524)
7520 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7522 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7523 (cons_to_x_long): New function.
7524 (lisp_data_to_selection_data): Use it. Correct the test for
7525 short-versus-long data; it was negated. Break out of vector
7526 loop, for efficiency, when a long datum is discovered.
7528 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7530 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7532 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7534 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7535 GCC PR/17406) by declaring this function with external scope.
7537 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7539 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7540 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7542 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7544 * editfns.c (Fformat): Correctly handle text properties on "%%".
7546 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7548 * xterm.c (x_draw_composite_glyph_string_foreground):
7549 * w32term.c (x_draw_composite_glyph_string_foreground):
7550 * term.c (encode_terminal_code):
7551 * composite.c (composition_update_it, get_composition_id):
7552 * xdisp.c (get_next_display_element)
7553 (fill_composite_glyph_string): Add comments about special meaning
7554 of TAB characters in a composition.
7556 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7558 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7559 This occurs when processing a multibyte format.
7560 Problem reported by Wolfgang Jenker.
7562 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7564 * xdisp.c (try_cursor_movement): Only check for exact match if
7565 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7567 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7569 Remove unused external symbols.
7570 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7571 * xdisp.c (calc_pixel_width_or_height): Now static.
7572 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7573 * indent.c (check_display_width):
7574 * w32term.c: Fix comment to match code.
7575 * xterm.c, xterm.h (x_catching_errors): Remove.
7577 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7579 * xselect.c: Use signed conversions more consistently (Bug#9498).
7580 (selection_data_to_lisp_data): Assume incoming selection data are
7581 signed integers, not unsigned. This is to be consistent with
7582 outgoing selection data, which was modified to use signed integers
7583 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7584 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7585 expects long, not unsigned long.
7587 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7589 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7590 computation of loop end. Reported by Johan Bockgård
7593 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7595 * frame.c (Fother_visible_frames_p): Function deleted.
7597 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7599 * indent.c (compute_motion): Process display vector front to back
7600 rather than the other way around. (Bug#2496)
7602 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7604 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7606 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7608 * minibuf.c (Fread_from_minibuffer): Doc fix.
7610 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7612 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7613 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7615 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7617 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7618 value for non-existent files.
7620 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7622 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7623 set its "size" to -1. This will set the modtime_size field of
7624 the corresponding buffer to -1, which is what
7625 verify-visited-file-modtime expects for files that do not exist.
7628 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7630 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7632 * lisp.h: ... from here. push_key_description is no longer
7633 defined in keyboard.c, so its declaration should not be in
7634 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7635 logically belongs with push_key_description.
7637 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7639 * buffer.h: Include <sys/types.h> instead of <time.h>.
7640 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7641 Problem reported by Herbert J. Skuhra.
7643 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7645 * xml.c (parse_region): Make the parsing work for
7646 non-comment-starting XML files again (bug#9144).
7648 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7650 * image.c (gif_load): Fix calculation of bottom and right corner.
7653 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7655 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7656 redisplay in small windows.
7658 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7660 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7662 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7664 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7665 Operate on live windows only.
7667 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7669 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7671 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7673 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7674 only under bidi iteration.
7676 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7678 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7680 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7682 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7683 Without this fix, the command to link temacs failed due to an
7684 undefined symbol __builtin_isnan. This is because
7685 /usr/include/iso/math_c99.h #defines isnan(x) to
7686 __builtin_isnan(x), but the bundled gcc, which identifies itself
7687 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7689 * floatfns.c (isnan): #undef, and then #define to a clone of
7691 (Fisnan): Always define, since it's always available now.
7692 (syms_of_floatfns): Always define isnan at the Lisp level.
7694 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7696 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7698 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7700 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7701 The previous code assumed that file offsets (off_t values) fit in
7702 EMACS_INT variables, which is not true on typical 32-bit hosts.
7703 The code messed up by falsely reporting buffer overflow in cases
7704 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7705 when "big" contains more than 2**29 bytes, even though this
7706 inserts just one byte and does not overflow the buffer.
7707 (Finsert_file_contents): Store file offsets as off_t
7708 values, not as EMACS_INT values. Check for overflow when
7709 converting between EMACS_INT and off_t. When checking for
7710 buffer overflow or for overlap, take the offsets into account.
7711 Don't use EMACS_INT for small values where int suffices.
7712 When checking for overlap, fix a typo: ZV was used where
7713 ZV_BYTE was intended.
7714 (Fwrite_region): Don't assume off_t fits into 'long'.
7715 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7717 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7719 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7721 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7723 sprintf-related integer and memory overflow issues (Bug#9412).
7725 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7726 (esprintf, exprintf, evxprintf): New functions.
7727 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7728 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7729 (modify_event_symbol): Do not assume that the length of
7730 name_alist_or_stem is safe to alloca and fits in int.
7731 (Fexecute_extended_command): Likewise for function name and binding.
7732 (Frecursion_depth): Wrap around reliably on integer overflow.
7733 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7734 since some callers pass EMACS_INT values.
7735 (Fsingle_key_description): Don't crash if symbol name contains more
7736 than MAX_ALLOCA bytes.
7737 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7738 (get_minibuffer): Arg is now EMACS_INT, not int.
7739 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7740 (esprintf, exprintf, evxprintf): New decls.
7741 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7743 * dbusbind.c (signature_cat): New function.
7744 (xd_signature, Fdbus_register_signal):
7745 Do not overrun buffer; instead, report string overflow.
7747 * dispnew.c (add_window_display_history): Don't overrun buffer.
7748 Truncate instead; this is OK since it's just a log.
7750 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7751 even if the time zone offset is outlandishly large.
7752 Don't mishandle offset == INT_MIN.
7754 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7755 when creating daemon; the previous buffer-overflow check was incorrect.
7757 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7758 which has the guts of the old verror function.
7760 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7761 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7763 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7764 (font_unparse_xlfd): Don't blindly alloca long strings.
7765 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7766 fits in int, when using sprintf. Use single snprintf to count
7767 length of string rather than counting it via multiple sprintfs;
7768 that's simpler and more reliable.
7769 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7770 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7771 sprintf, in case result does not fit in int.
7773 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7774 (fontset_from_font): Print it.
7776 * frame.c (tty_frame_count): Now printmax_t, not int.
7777 (make_terminal_frame, set_term_frame_name): Print it.
7778 (x_report_frame_params): In X, window IDs are unsigned long,
7779 not signed long, so print them as unsigned.
7780 (validate_x_resource_name): Check for implausibly long names,
7781 and don't assume name length fits in 'int'.
7782 (x_get_resource_string): Don't blindly alloca invocation name;
7783 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7786 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7787 (xg_check_special_colors, xg_set_geometry):
7788 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7790 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7791 Use esprintf, not sprintf, in case result does not fit in int.
7793 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7794 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7795 it as a large positive number.
7796 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7797 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7799 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7800 in case result does not fit in int.
7802 * print.c (float_to_string): Detect width overflow more reliably.
7803 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7804 buffer overrun. Don't assume list length fits in 'int'. Treat
7805 print length of 0 as 0, not as infinity; to be consistent with other
7806 uses of print length in this function. Don't overflow print length
7807 index. Don't assume hash table size fits in 'long', or that
7808 vectorlike size fits in 'unsigned long'.
7810 * process.c (make_process): Use printmax_t, not int, to format
7811 process-name gensyms.
7813 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7815 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7816 to avoid potential buffer overrun.
7818 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7819 if X resource line is longer than 512 bytes.
7821 * xfns.c (x_window): Make sprintf buffer a bit bigger
7822 to avoid potential buffer overrun.
7824 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7826 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7828 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7830 Integer overflow fixes for scrolling, etc.
7831 Without these, Emacs silently mishandles large integers sometimes.
7832 For example, "C-u 4294967297 M-x recenter" was treated as if
7833 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7835 * xdisp.c (try_window_id): Check Emacs fixnum range before
7836 converting to 'int'.
7838 * window.c (window_scroll_line_based, Frecenter):
7839 Check that an Emacs fixnum is in range before assigning it to 'int'.
7840 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7841 values converted from Emacs fixnums.
7842 (Frecenter): Don't wrap around a line count if it is out of 'int'
7843 range; instead, treat it as an extreme value.
7844 (Fset_window_configuration, compare_window_configurations):
7845 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7847 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7848 that can exceed INT_MAX. Check that EMACS_INT value is in range
7849 before assigning it to the (possibly-narrower) index.
7850 (match_limit): Don't assume that a fixnum can fit in 'int'.
7852 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7855 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7856 (Fvertical_motion): Don't wrap around LINES values that don't fit
7857 in 'int'. Instead, treat them as extreme values. This is good
7858 enough for windows, which can't have more than INT_MAX lines anyway.
7860 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7862 * Require libxml/parser.h to avoid compilation warning.
7864 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7866 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7867 since this reportedly can destroy thread storage.
7869 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7871 * syntax.c (find_defun_start): Update all cache variables if
7872 exiting early (Bug#9401).
7874 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7876 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7878 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7879 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7880 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7882 * term.c (tty_append_glyph): New function.
7883 (produce_stretch_glyph): Static function and its prototype deleted.
7885 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7888 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7890 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7891 when checking :margin (Bug#9390).
7892 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7893 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7894 so that the name doesn't mislead. All uses changed.
7896 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7898 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7901 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7903 * xdisp.c (move_it_to): Don't bail out early when reaching
7904 position beyond to_charpos, if we are scanning backwards.
7905 (move_it_vertically_backward): When DY == 0, make sure we get to
7906 the first character in the line after the newline.
7908 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7910 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7911 (ccl_driver): Do not generate an out-of-range pointer.
7912 (Fccl_execute_on_string): Remove unnecessary check for
7913 integer overflow, noted by Stefan Monnier in
7914 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7915 Remove a FIXME that didn't need fixing.
7916 Simplify the newly-introduced buffer reallocation code.
7918 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7920 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7922 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7924 Integer and memory overflow issues (Bug#9196).
7926 * doc.c (get_doc_string): Rework so that
7927 get_doc_string_buffer_size is the actual buffer size, rather than
7928 being 1 less than the actual buffer size; this makes xpalloc more
7931 * image.c (x_allocate_bitmap_record, cache_image):
7932 * xselect.c (Fx_register_dnd_atom):
7933 Simplify previous changes by using xpalloc.
7935 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7936 since either will do and ptrdiff_t is convenient with xpalloc.
7938 * charset.c (charset_table_size)
7939 (struct charset_sort_data.priority): Now ptrdiff_t.
7940 (charset_compare): Don't overflow if priorities differ greatly.
7941 (Fsort_charsets): Don't assume list length fits in int.
7942 Check for size-calculation overflow when allocating sort data.
7943 (syms_of_charset): Allocate an initial charset table that is
7944 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7946 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7948 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7949 The actual value is always <= INT_MAX, and leaving it unsigned made
7950 overflow checking harder.
7952 * dispextern.h (struct glyph_matrix.rows_allocated)
7953 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7954 with xpalloc. The values are still always <= INT_MAX.
7956 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7958 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7959 (SAFE_NALLOCA): New macro.
7961 * region-cache.c (struct boundary.pos, find_cache_boundary)
7962 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7963 (set_cache_region, invalidate_region_cache)
7964 (revalidate_region_cache, know_region_cache, region_cache_forward)
7965 (region_cache_backward, pp_cache):
7966 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7967 so that ptrdiff_t * can be passed to xpalloc.
7968 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7969 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7970 (pp_cache): Don't assume cache_len fits in int.
7971 * region-cache.h: Adjust extern decls to match.
7973 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7974 EMACS_INT, since either will do, for xpalloc.
7976 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7977 (xnmalloc, xnrealloc, xpalloc): New functions.
7979 * bidi.c (bidi_shelve_header_size): New constant.
7980 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7981 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7983 * bidi.c (bidi_cache_shrink):
7984 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7986 Don't update size of array until after memory allocation succeeds,
7987 because xmalloc/xrealloc may not return.
7988 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7989 now that we have proper integer overflow checking.
7990 (record_overlay_string, overlay_strings): Catch overflows when
7991 calculating size of overlay_str_buf.
7993 * callproc.c (Fcall_process): Check for size overflow when
7994 calculating size of args2.
7995 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7996 Normally we prefer signed values, but sticking with ptrdiff_t would
7997 require adding more-complicated checks.
7999 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8000 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8001 Redo buffer-overflow calculations to avoid integer overflow.
8002 Add a FIXME comment where memory seems to be over-allocated.
8004 * character.c (Fstring): Check for size-calculation overflow.
8006 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8007 unnecessary integer overflow. Check for size overflow.
8008 (encode_coding_object): Don't update size until xmalloc succeeds.
8010 * composite.c (get_composition_id): Check for overflow in glyph
8011 length calculations.
8013 Integer and memory overflow fixes for display code.
8014 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8015 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8016 (scrolling_window): Check for overflow in size calculations.
8017 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8018 Don't assume glyph table len fits in int.
8019 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8020 (row_table_size): Now ptrdiff_t, not int.
8021 (scrolling_window): Avoid overflow in size calculations.
8022 Don't update size until allocation succeeds.
8023 * fns.c (concat): Check for overflow in size calculations.
8024 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8025 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8026 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8028 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8029 (get_doc_string): Check for size calculation overflow.
8030 Don't update size until allocation succeeds.
8031 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8032 EMACS_INT, where ptrdiff_t will do.
8033 (Fsubstitute_command_keys): Check for string overflow.

8037 (message_length): Now ptrdiff_t, not int.
8038 (Fmessage_box): Don't update size until allocation succeeds.
8039 Don't assume message length fits in int.
8040 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8042 * emacs.c (main): Do not reallocate argv, since there is a null at
8043 the end that can be overwritten, and this way there's no need to
8044 worry about size-calculation overflow.
8045 (sort_args): Check for size-calculation overflow.
8047 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8049 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8051 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8052 (x_set_scroll_bar_width, x_figure_window_size):
8053 Check for integer overflow.
8054 (x_set_alpha): Do not assume XINT fits in int.
8056 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8057 This is for the members text_lines, text_cols, total_lines, total_cols,
8058 where the system imposes an 'int' limit.
8060 * fringe.c (Fdefine_fringe_bitmap):
8061 Don't update size until alloc works.
8063 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8064 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8066 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8067 Check for size-calculation overflow.
8068 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8069 do, as we prefer signed integers.
8070 (id_to_widget.max_size, id_to_widget.used)
8071 (xg_store_widget_in_map, xg_remove_widget_from_map)
8072 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8073 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8074 Use and return ptrdiff_t, not int.
8075 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8076 * gtkutil.h: Change prototypes to match the above.
8078 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8079 are duplicate now that they've been promoted to lisp.h.
8080 (x_allocate_bitmap_record, x_alloc_image_color)
8081 (make_image_cache, cache_image, xpm_load):
8082 Don't update size until alloc is done.
8083 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8085 Check for size calculation overflow.
8086 (ct_colors_allocated_max): New constant.
8087 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

8092 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8093 Use ptrdiff_t, not int, to count maps.
8094 (read_char_minibuf_menu_prompt): Check for overflow in size
8095 calculations. Don't update size until allocation succeeds.

8107 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8109 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8110 Now ptrdiff_t, not int.
8111 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8112 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
8114 * process.c (Fnetwork_interface_list): Check for overflow
8115 in size calculation.
8117 * region-cache.c (move_cache_gap): Check for size calculation overflow.

8123 (Fset_match_data): Don't assume list lengths fit in 'int'.
8125 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8126 for command line length. Do not attempt to address one before the
8127 beginning of an array, as that's not portable.
8129 * term.c (max_frame_lines): Remove; unused.
8130 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8132 (encode_terminal_code, calculate_costs): Check for size
8133 calculation overflow.

8139 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
8140 subtracting pointers.

8155 Use ptrdiff_t, not int, for sizes.
8156 (Finternal_make_lisp_face, cache_face):
8157 Check for size calculation overflow.
8158 (cache_face): Treat size calculation overflows as if they were
8159 memory exhaustion (the usual treatment), rather than aborting.
8161 * xfns.c (x_encode_text, x_set_name_internal)
8162 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8163 sizes, since they can exceed INT_MAX in size. Check for size

8167 (xg_select): Check for size calculation overflow.
8168 Don't update size until alloc done.

8174 (X_LONG_MIN): New macros.
8175 Use them to make the following changes clearer.
8176 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8177 This change doesn't affect the value now, but it may help remind
8178 future maintainers not to raise the value too much later.
8179 (SELECTION_QUANTUM): Remove, replacing with ...
8180 (selection_quantum): ... new function, which avoids overflow.
8182 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8183 assumption that selection length fits in 'int'.
8184 (x_reply_selection_request, x_handle_selection_request)
8185 (x_get_window_property, receive_incremental_selection)
8186 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8187 (lisp_data_to_selection_data, clean_local_selection_data):

8189 (x_reply_selection_request, x_get_window_property)
8190 (receive_incremental_selection, x_property_data_to_lisp):
8191 Redo calculations to avoid overflow.
8192 (x_reply_selection_request): When sending hint, ceiling it at
8193 X_LONG_MAX rather than relying on wraparound overflow to send
8195 (x_get_window_property, receive_incremental_selection)
8196 (lisp_data_to_selection_data, x_property_data_to_lisp):
8197 Check for size-calculation overflow.

8200 Don't store size until memory allocation succeeds.
8201 (x_get_window_property): Plug memory leak on memory exhaustion.
8202 Don't double-block input; malloc is safe here. Don't assume 2**34
8203 - 4 fits in unsigned long. Add an xassert to check
8204 XGetWindowProperty overflow. Be more careful about overflow
8205 calculations, and distinguish size from memory overflow better.
8206 (receive_incremental_selection): When tracing, don't assume
8207 unsigned int is less than INT_MAX.
8208 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8209 harmful) conversions of unsigned short to int.
8210 (lisp_data_to_selection_data): Don't assume that integers
8211 in the range -65535 through -1 fit in an X unsigned short.
8212 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8213 result parameters unless successful. Rely on cons_to_unsigned
8214 to report problems with elements; the old code wasn't right anyway.
8215 (x_check_property_data): Check for int overflow; we cannot use
8216 a wider type due to X limits.
8217 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8219 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8221 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8222 (x_term_init): Check for size calculation overflow.
8223 (x_color_cells): Don't store size until memory allocation succeeds.
8224 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.

8248 * image.c (xpm_get_color_table_h):
8249 * lisp.h (hash_lookup, hash_put):
8250 * minibuf.c (Ftest_completion):
8251 Use ptrdiff_t for hash table indexes, not int (which is too
8252 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8253 32-bit --with-wide-int hosts).
8255 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8256 Add a FIXME comment about memory leaks.
8257 (syms_of_charset): Don't assume xmalloc returns.
8259 Don't assume that stated character widths fit in int.

8261 * character.h (CHAR_WIDTH):
8262 * indent.c (MULTIBYTE_BYTES_WIDTH):
8263 Use sanitize_char_width to avoid undefined and/or bad behavior
8264 with outlandish widths.
8265 * character.h (sanitize_tab_width): Rename from sanitize_width,
8266 now that we have two such functions. All uses changed.
8267 (sanitize_char_width): New inline function.
8269 Don't assume that tab-width fits in int.
8270 * character.h (sanitize_width): New inline function.
8271 (SANE_TAB_WIDTH): New macro.
8272 (ASCII_CHAR_WIDTH): Use it.
8273 * indent.c (sane_tab_width): Remove. All uses replaced by
8274 SANE_TAB_WIDTH (current_buffer).
8275 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
8277 * fileio.c: Integer overflow issues with file modes.
8278 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
8280 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
8281 Remove unreachable code.

8284 * xterm.c: Don't go over XClientMessageEvent limit.
8285 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8286 (x_send_scroll_bar_event): Likewise. Check that the size does not
8287 exceed limits imposed by XClientMessageEvent, as well as the usual
8288 ptrdiff_t and size_t limits.
8290 * keyboard.c: Overflow, signedness and related fixes.
8291 (make_lispy_movement): Use same integer type in forward decl
8292 that is used in the definition.
8293 (read_key_sequence, keyremap_step):
8294 Change bufsize argument back to int, undoing my 2011-03-30 change.
8295 We prefer signed types, and int is wide enough here.
8296 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8297 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8298 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8299 length, not size_t. Use ptrdiff_t for index, not int.
8300 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8301 possibility of integer overflow.
8303 Overflow, signedness and related fixes for images.

8313 * xdisp.c (calc_pixel_width_or_height):
8314 * xfns.c (image_cache_refcount):
8315 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8316 on typical 64-bit hosts.
8318 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8319 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8324 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8325 (lookup_image): Remove unnecessary tests.
8326 (xbm_image_p): Locals are now of int, not EMACS_INT,
8327 since parse_image_check makes sure they fit into int.
8328 (png_load, gif_load, svg_load_image):
8329 Prefer int to unsigned where either will do.
8330 (tiff_handler): New function, combining the cores of the
8331 old tiff_error_handler and tiff_warning_handler.
8332 This function is rewritten to use vsnprintf and thereby avoid
8333 stack buffer overflows. It uses only the features of vsnprintf
8334 that are common to both POSIX and native Microsoft.
8335 (tiff_error_handler, tiff_warning_handler): Use it.
8336 (tiff_load, gif_load, imagemagick_load_image):
8337 Don't assume :index value fits in 'int'.
8338 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8339 (imagemagick_load_image): Check that crop parameters fit into
8340 the integer types that MagickCropImage accepts. Don't assume
8341 Vimagemagick_render_type has a nonnegative value. Don't assume
8342 size_t fits in 'long'.
8343 (gs_load): Use printmax_t to print the widest integers possible.
8344 Check for integer overflow when computing image height and width.
8346 2011-08-26 Eli Zaretskii <eliz@gnu.org>
8348 * xdisp.c (redisplay_window): Don't force window start if point
8349 will be invisible in the resulting window. (Bug#9324)
8351 2011-08-25 Eli Zaretskii <eliz@gnu.org>
8353 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8354 the display spec is of the form `(space ...)'.
8355 (handle_display_spec): Return the value returned by
8356 handle_single_display_spec, not just 1 or zero.
8357 (handle_single_display_spec): If the display spec is of the form
8358 `(space ...)', and specifies display in the text area, return 2
8360 (try_cursor_movement): Check for the need to scroll more
8361 accurately, and prefer exact match for point under bidi.
8362 Don't advance `row' beyond the last row of the window.
8364 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8365 into disp_prop; all users changed.
8367 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8368 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8369 for the text covered by the display property.
8371 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8373 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8379 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8380 buffers, return left-to-right.
8381 (set_cursor_from_row): Consider candidate row a win if its glyph
8382 represents a newline and point is on that newline. Fixes cursor
8383 positioning on the newline at EOL of R2L text within L2R
8384 paragraph, and vice versa.
8385 (try_cursor_movement): Check continued rows, in addition to
8386 continuation rows. Fixes unwarranted scroll when point enters a
8387 continued line of R2L text within an L2R paragraph, or vice versa.
8388 (cursor_row_p): Consider the case of point being equal to
8389 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8390 from the end of a short line to the beginning of a continued line
8391 of R2L text within L2R paragraph.
8392 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8393 composed characters.
8395 * bidi.c (bidi_check_type): Use xassert.
8396 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p

8406 * nsfont.m (ns_otf_to_script): Fix typo.
8408 2011-08-22 Kenichi Handa <handa@m17n.org>
8410 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8411 extra slot even if the purpose is char-code-property-table.
8413 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8415 * xdisp.c (redisplay_window): When computing centering_position,
8416 account for the height of the header line. (Bug#8874)
8418 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8419 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8420 candidate is selected by the mouse, and that candidate has a
8421 composed character under the mouse.
8423 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8424 coordinates reported by pos-visible-in-window-p for a composed
8425 character in column zero.
8427 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8429 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8431 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8433 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8434 consider it a hit if to_charpos is anywhere in the range of the
8435 composed buffer positions.
8437 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8439 * image.c (gif_load): Don't assume that each subimage has the same
8440 dimensions as the base image. Handle disposal method that is
8441 "undefined" by the gif spec (Bug#9335).
8443 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8445 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8446 (Fcondition_case): Document `debug' symbol in error handler.
8448 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8450 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8451 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8452 from an Org mode buffer to a Speedbar frame.
8454 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8455 a composition, take its buffer position from IT->cmp_it.charpos.
8456 Fixes cursor positioning at the beginning of a line that begins
8457 with a composed character.
8459 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8461 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8462 character bidirectional type, use STRONG_L instead. Fixes crashes
8463 in a buffer produced by `describe-categories'.
8465 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8466 members before the level stack, so they would be saved and
8467 restored when copying iterator state. Fixes incorrect reordering
8468 around TABs covered by display properties.
8470 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8472 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8477 (internal_condition_case_2, internal_condition_case_n):
8478 Remove unnecessary aborts (Bug#9081).
8480 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8482 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8483 has no `load' handler, try opening the file locally. (Bug#9311)
8485 2011-08-16 Ken Brown <kbrown@cornell.edu>
8487 * gmalloc.c: Expand comment.
8489 2011-08-16 Eli Zaretskii <eliz@gnu.org>

8505 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8507 [CYGWIN] (special_realloc): New function.
8508 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8509 requests to realloc storage in the static heap.

8524 * chartab.c: Improve commentary for the uniprop_table API.
8526 * bidi.c (bidi_paragraph_init): Support zero value of
8527 bidi_ignore_explicit_marks_for_paragraph_level.
8528 (bidi_initialize): Use uniprop_table instead of including
8529 biditype.h and bidimirror.h.

8542 * xdisp.c (move_it_in_display_line_to): Don't invoke
8543 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8544 ppos_it. Fixes vertical cursor motion when line beginning is
8545 covered by an image. (Bug#9296)
8547 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8549 * nsterm.h (ns_run_ascript): Declare.

8552 * nsfns.m (as_script, as_result, as_status): New static variables.
8553 (ns_run_ascript): New function.
8554 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8555 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8556 the event loop. Get status from as_status (Bug#7276).
8558 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8559 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8560 the event loop (Bug#7276).
8562 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8564 * gnutls.c (QCgnutls_bootprop_priority)

8578 * xfaces.c (Qframe_set_background_mode): Now static.
8579 * dispextern.h (Qframe_set_background_mode): Remove decl.
8581 * process.c (Fnetwork_interface_info): Declare local only if needed.
8583 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8585 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8586 (Fnetwork_interface_list): Allocate in increments of bytes instead
8587 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8588 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8590 (struct ifflag_def): notrailers is smart on OSX.
8591 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8592 Get hardware address with getifaddrs if available.
8594 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8596 * xdisp.c (iterate_out_of_display_property): xassert that
8597 IT->position is set to within IT->object's boundaries. Break from
8598 the loop as soon as EOB is reached; avoids infloops in redisplay
8599 when IT->position is set up wrongly due to some bug.
8600 Set IT->current to match the bidi iterator unconditionally.
8601 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8602 entry. Force push_it to save on the stack the current
8603 buffer/string position, to be restored by pop_it. Fix flags in
8604 the iterator structure wrt the object coming from a display
8605 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8606 properties. (Bug#9284)
8608 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8610 * fontset.c (fontset_get_font_group): Add proper type checks.

8616 and LC_VERSION_MIN_MACOSX.
8617 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8618 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8620 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8622 * xdisp.c (forward_to_next_line_start): Allow to use the
8623 no-display-properties-and-no-overlays under bidi display.
8624 Set disp_pos in the bidi iterator to avoid searches for display
8625 properties and overlays.
8627 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8629 * editfns.c (Fset_time_zone_rule): Document relationship with the
8632 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8633 the font entity extracted from the cache (Bug#8109).
8635 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8637 * composite.c (autocmp_chars): Don't reset point. That is done by
8638 restore_point_unwind (Bug#5984).
8640 2011-08-07 Juri Linkov <juri@jurta.org>
8642 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8643 to show the arg `TIME' instead of `TIMEVAL'.
8645 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8647 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8648 display property strides EOL and includes a newline, as in
8649 longlines-mode. (Bug#9254)
8650 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8651 word-wrap under bidirectional display. (Bug#9224)
8653 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8654 is non-zero, even if the data buffer is NULL. Fixes a crash in
8655 vertical-motion with longlines-mode. (Bug#9254)
8657 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8659 * bidi.c <bidi_cache_total_alloc>: Now static.
8660 (bidi_initialize): Initialize bidi_cache_total_alloc.
8662 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8665 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8666 amount allocated this far in `bidi_cache_total_alloc'.
8667 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8668 non-zero, only free the data buffer without restoring the cache
8669 contents. All callers changed.
8671 * dispextern.h (bidi_unshelve_cache): Update prototype.
8673 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8674 (move_it_in_display_line, move_it_to)
8675 (move_it_vertically_backward, move_it_by_lines): Replace the call
8676 to xfree to an equivalent call to bidi_unshelve_cache.
8677 (move_it_in_display_line_to): Fix logic of returning
8678 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8680 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8682 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8683 came from a string character with a `cursor' property. (Bug#9229)
8685 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8687 * Makefile.in (LIB_PTHREAD): New variable.
8688 (LIBES): Add LIB_PTHREAD (Bug#9216).
8690 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8691 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8693 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8695 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8697 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8699 * xterm.c (x_find_topmost_parent): New function.
8700 (x_set_frame_alpha): Find topmost parent window with
8701 x_find_topmost_parent and set the property there also (bug#9181).
8702 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8704 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8706 * callproc.c (Fcall_process): Avoid vfork clobbering
8707 the local vars buffer, coding_systems, current_dir.
8709 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8711 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8713 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8715 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8716 so that it is not optimized away.
8718 * xdisp.c (compute_display_string_pos): Remove unused local.
8720 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8722 Fix slow cursor motion and scrolling in large buffers with
8723 selective display, like Org Mode buffers. (Bug#9218)
8725 * dispextern.h (struct bidi_it): New member disp_prop_p.
8727 * xdisp.c: Remove one-slot cache of display string positions.
8728 (compute_display_string_pos): Accept an additional argument
8729 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8730 for a display string or property. If found, set DISP_PROP_P
8733 * bidi.c (bidi_fetch_char): Accept an additional argument
8734 DISP_PROP_P, and pass it to compute_display_string_pos.
8735 Only handle text covered by a display string if DISP_PROP_P is returned
8736 non-zero. All callers of bidi_fetch_char changed.
8738 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8740 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8742 2010-12-03 Don March <don@ohspite.net>
8744 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8745 last character M-[char] is translated to ESC [char] (bug#7541).
8747 2011-08-02 Kenichi Handa <handa@m17n.org>
8749 * lisp.h (uniprop_table): Extern it.
8751 * chartab.c (uniprop_table): Make it non-static.
8753 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8755 * xdisp.c (forward_to_next_line_start): Accept additional argument
8756 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8758 (reseat_at_next_visible_line_start): Use the bidi iterator state
8759 returned by forward_to_next_line_start to restore the state of
8760 it->bidi_it after backing up to previous newline. (Bug#9212)
8762 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8764 * regex.c (re_comp): Protoize.
8765 (re_exec): Fix return type.
8766 (regexec): Fix type of `ret'. (Bug#9203)
8768 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8770 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8771 This is needed if max-image-size is a floating-point number.
8773 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8775 * print.c (print_object): Print empty symbol as ##.
8777 * lread.c (read1): Read ## as empty symbol.
8779 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8781 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8782 setting frame foreground color (Bug#9175).
8783 (x_set_background_color): Likewise.
8785 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8786 contents (Bug#9176).
8787 (EmacsTooltip -init): Remove bezels and add shadows to
8790 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8791 or scroll bar (Bug#8470).
8793 * nsfont.m (nsfont_open): Remove assignment to voffset and
8794 unnecessary vars hshink, expand, hd, full_height, min_height.
8795 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8797 * nsterm.h (nsfont_info): Remove voffset field.
8799 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8801 Implement strike-through and overline on NextStep (Bug#8863).
8803 * nsfont.m (nsfont_open): Use underline position provided by font,
8804 instead of hard-coded value of 2.
8805 (nsfont_draw): Call ns_draw_text_decoration instead.
8807 * nsterm.h: Add declaration for ns_draw_text_decoration.
8809 * nsterm.m (ns_draw_text_decoration): New function for drawing
8810 underline, overline, and strike-through.
8811 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8812 ns_draw_text_decoration. Change treatment of cursor drawing to
8813 accommodate underlining, etc.
8815 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8817 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8820 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8822 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8823 Without this fix, if a signal arrives just after memory fills up,
8824 'malloc' might be invoked reentrantly.
8826 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8827 In other words, assume that every image size is allowed, on non-X
8828 hosts. This assumption is probably wrong, but it lets Emacs compile.
8830 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8832 * regex.c (re_iswctype): Convert return values to boolean.
8834 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8836 * xdisp.c (compute_display_string_pos): Don't use cached display
8837 string position if the buffer had its restriction changed.
8840 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8842 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8844 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8846 Integer signedness and overflow and related fixes. (Bug#9079)
8848 * bidi.c: Integer size and overflow fixes.
8849 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8850 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8851 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8852 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8853 (bidi_find_other_level_edge):
8854 Use ptrdiff_t instead of EMACS_INT where either will do.
8855 This works better on 32-bit hosts configured --with-wide-int.
8856 (bidi_cache_ensure_space): Check for size-calculation overflow.
8857 Use % rather than repeated addition, for better worst-case speed.
8858 Don't set bidi_cache_size until after xrealloc returns, because it
8860 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8861 (bidi_cache_ensure_space): Also check that the bidi cache size
8862 does not exceed that of the largest Lisp string or buffer. See Eli
8863 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8865 * alloc.c (__malloc_size_t): Remove.
8866 All uses replaced by size_t. See Andreas Schwab's note
8867 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8869 * image.c: Improve checking for integer overflow.
8870 (check_image_size): Assume that f is nonnull, since
8871 it is always nonnull in practice. This is one less thing to
8872 worry about when checking for integer overflow later.
8873 (x_check_image_size): New function, which checks for integer
8874 overflow issues inside X.
8875 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8876 This removes the need for a memory_full check.
8877 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8878 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8879 (xbm_read_bitmap_data): Change locals back to 'int', since
8880 their values must fit in 'int'.
8881 (xpm_load_image, png_load, tiff_load):
8882 Invoke x_create_x_image_and_pixmap earlier,
8883 to avoid much needless work if the image is too large.
8884 (tiff_load): Treat overly large images as if
8885 x_create_x_image_and_pixmap failed, not as malloc failures.
8886 (gs_load): Use x_check_image_size.
8888 * gtkutil.c: Omit integer casts.
8889 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8890 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8892 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8894 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8895 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8896 would wrongly return t on a 64-bit host.
8898 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8899 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8900 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8901 and therefore cause GCC to emit a bogus diagnostic in some cases.
8903 * image.c: Integer signedness and overflow and related fixes.
8904 This is not an exhaustive set of fixes, but it's time to
8905 record what I've got.
8906 (lookup_pixel_color, check_image_size): Remove redundant decls.
8907 (check_image_size): Don't assume that arbitrary EMACS_INT values
8908 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8909 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8910 (tiff_load, imagemagick_load_image):
8911 Check for overflow in size calculations.
8912 (x_create_x_image_and_pixmap): Remove unnecessary test for
8913 xmalloc returning NULL; that can't happen.
8914 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8915 (xpm_color_bucket): Use better integer hashing function.
8916 (xpm_cache_color): Don't possibly over-allocate memory.
8917 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8918 (gif_memory_source):
8919 Use ptrdiff_t, not int or size_t, to record sizes.
8920 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8921 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8922 either works, as we prefer signed integers.
8923 (tiff_read_from_memory, tiff_write_from_memory):
8924 Return tsize_t, not size_t, since that's what the TIFF API wants.
8925 (tiff_read_from_memory): Don't fail simply because the read would
8926 go past EOF; instead, return a short read.
8927 (tiff_load): Omit no-longer-needed casts.
8928 (Fimagemagick_types): Don't assume size fits into 'int'.
8930 Improve hashing quality when configured --with-wide-int.
8931 * fns.c (hash_string): New function, taken from sxhash_string.
8932 Do not discard information about ASCII character case; this
8933 discarding is no longer needed.
8934 (sxhash-string): Use it. Change sig to match it. Caller changed.
8935 * lisp.h: Declare it.
8936 * lread.c (hash_string): Remove, since we now use fns.c's version.
8937 The fns.c version returns a wider integer if --with-wide-int is
8938 specified, so this should help the quality of the hashing a bit.
8940 * emacs.c: Integer overflow minor fix.
8941 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8942 Define only if GNU_LINUX.
8943 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8945 * dispnew.c: Integer signedness and overflow fixes.
8946 Remove unnecessary forward decls, that were a maintenance hassle.
8947 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8949 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8950 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8951 (prepare_desired_row, line_draw_cost):
8952 Use int, not unsigned, where either works.
8953 (save_current_matrix, restore_current_matrix):
8954 Use ptrdiff_t, not size_t, where either works.
8955 (init_display): Check for overflow more accurately, and without
8956 relying on undefined behavior.
8958 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8959 Remove, replacing with the new symbols in lisp.h. All uses changed.
8960 * fileio.c (make_temp_name):
8961 * filelock.c (lock_file_1, lock_file):
8962 * xdisp.c (message_dolog):
8963 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8964 Use pMd etc. instead.
8965 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8966 replacing the pWIDE etc. symbols removed from editfns.c.
8968 * keyboard.h (num_input_events): Now uintmax_t.
8969 This is (very slightly) less likely to mess up due to wraparound.
8972 * buffer.c: Integer signedness fixes.
8973 (alloc_buffer_text, enlarge_buffer_text):
8974 Use ptrdiff_t rather than size_t when either will do, as we prefer
8977 * alloc.c: Integer signedness and overflow fixes.
8978 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8979 (__malloc_size_t): Default to size_t, not to int.
8980 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8981 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8982 Prefer ptrdiff_t to size_t when either would do, as we prefer
8984 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8985 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8986 Now const. Initialize with values that are in range even if char
8988 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8989 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8990 These functions do the right thing with sizes > 2**32.
8991 (check_depth): Now ptrdiff_t, not int.
8992 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8993 Adjust to new way of storing sizes. Check for size overflow bugs
8995 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8996 slightly wrong anyway, as it missed one instance of
8997 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8998 (refill_memory_reserve): Omit needless cast to size_t.
8999 (mark_object_loop_halt): Mark as externally visible.
9001 * xselect.c: Integer signedness and overflow fixes.
9002 (Fx_register_dnd_atom, x_handle_dnd_message):
9003 Use ptrdiff_t, not size_t, since we prefer signed.
9004 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9005 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9006 x_dnd_atoms_size and x_dnd_atoms_length.
9008 * doprnt.c: Prefer signed to unsigned when either works.
9010 * doprnt.c (doprnt):
9012 * xdisp.c (vmessage):
9013 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9014 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9015 prefer signed arithmetic to avoid comparison confusion.
9016 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9017 but is a bit tricky.
9019 Assume freestanding C89 headers, string.h, stdlib.h.
9020 * data.c, doprnt.c, floatfns.c, print.c:
9021 Include float.h unconditionally.
9022 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9023 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9024 * regex.c: Likewise for stddef.h, string.h.
9025 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9026 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9027 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9028 (STDC_HEADERS): Remove obsolete defines.
9029 * sysdep.c: Include limits.h unconditionally.
9031 Assume support for memcmp, memcpy, memmove, memset.
9032 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9033 * regex.c (memcmp, memcpy):
9034 Remove; we assume C89 now.
9036 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9037 (__malloc_safe_bcopy): Remove; no longer needed.
9039 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9040 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9041 well either way, and we prefer signed to unsigned.
9043 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9045 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9046 closes the connection while we're reading (bug#9182).
9048 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9050 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9051 are specified (Bug#9168).
9053 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9055 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9056 Found by GCC static checking and --with-wide-int on a 32-bit host.
9058 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9060 * xdisp.c (compute_display_string_pos): Fix logic of caching
9061 previous display string position. Initialize cached_prev_pos to
9062 -1. Fixes slow-down at the beginning of a buffer.
9064 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9066 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9067 for attrs[LFACE_FONTSET_INDEX].
9069 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9071 * xml.c (parse_region): Remove unused local
9072 that was recently introduced.
9074 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9076 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9077 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9079 * xdisp.c (move_it_in_display_line_to): Record the best matching
9080 position for TO_CHARPOS while scanning the line, and restore it on
9081 exit if none of the characters scanned was an exact match.
9082 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9083 when exact match is impossible due to invisible text, and the
9084 lines are truncated.
9086 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9088 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9091 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9093 Fix a significant slow-down of cursor motion with C-n, C-p,
9094 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9095 auto-repeat under bidi redisplay in fontified buffers.
9096 * xdisp.c (compute_stop_pos_backwards): New function.
9097 (next_element_from_buffer): Call compute_stop_pos_backwards to
9098 find a suitable prev_stop when we find ourselves before
9100 (reseat): Don't look for prev_stop, as that could mean a very long
9102 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9103 <cached_disp_overlay_modiff>: Cache for last found display string
9105 (compute_display_string_pos): Return the cached position if asked
9106 about the same buffer in the same area of character positions, and
9107 the buffer wasn't changed since the time the display string
9108 position was cached.
9110 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9112 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9113 is an integer, which is important for empty lines. (Bug#9149)

9117 * frame.c (Fmodify_frame_parameters): In tty case, update the
9118 default face if necessary (Bug#4238).
9120 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9122 * editfns.c (Fstring_to_char): No need to explain what a character
9123 is in the docstring (Bug#6576).
9125 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9127 * xml.c (parse_region): Make sure we always return a tree.
9129 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>

9141 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9142 and the surrounding thread.
9143 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9144 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9145 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9147 * s/openbsd.h (BROKEN_SIGIO): Define.
9148 * unexelf.c (unexec) [__OpenBSD__]:
9149 Don't update the .mdebug section of the Alpha COFF symbol table.
9151 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9153 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9156 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>

9159 This fixes some race conditions on the permissions of any newly
9162 * alloc.c (valid_pointer_p): Use pipe, not open.
9163 This fixes some permissions issues when debugging.
9165 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9166 If fchown fails to set both uid and gid, try to set just gid,
9167 as that is sometimes allowed. Adjust the file's mode to eliminate
9168 setuid or setgid bits that are inappropriate if fchown fails.
9170 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9172 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

9186 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9188 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9189 This works around a problem with the previous change to Fcopy_file.
9190 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9191 and without this change, GCC might complain about discarding
9192 fchown's return value.
9194 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9196 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9198 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9200 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9202 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9204 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9205 it's used from the C level.
9207 * process.c: Use the same condition for POLL_FOR_INPUT in both
9208 keyboard.c and process.c (bug#1858).

9217 * doc.c (Fsubstitute_command_keys): Revert last change.
9219 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9221 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9222 quotes the next character, and doesn't affect other longer
9223 sequences (bug#8935).
9225 * lread.c (syms_of_lread): Clarify that is isn't only
9226 `eval-buffer' and `eval-defun' that's affected by
9227 `lexical-binding' (bug#8460).

9237 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9238 (elsz): Now a signed constant, not a size_t var. We prefer signed
9239 types to unsigned, to avoid integer comparison confusion. Without
9240 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9241 "cannot optimize loop, the loop counter may overflow", a symptom
9243 * indent.c (Fvertical_motion): Mark locals as initialized.
9244 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9246 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9248 * search.c (Fre_search_backward): Mention `case-fold-search' in
9249 all the re_search_* functions (bug#8138).

9272 (display_string): If we need to ignore text properties of
9273 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

9284 Fix calculation of the object to scan. Fixes an error when using
9286 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9287 base_level_stop; instead, set base_level_stop to BEGV.
9288 Fixes crashes in vertical-motion.
9289 (next_element_from_buffer): Improve commentary for when
9290 the iterator is before prev_stop.
9291 (init_iterator): Initialize bidi_p from the default value of
9292 bidi-display-reordering, not from buffer-local value. Use the
9293 buffer-local value only if initializing for buffer iteration.

9314 parts of next_element_from_buffer, next_element_from_string, and
9315 next_element_from_c_string.

9332 pushed the iterator stack, restore the internal state of the bidi
9333 iterator by calling bidi_pop_it same number of times.
9334 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9335 and we are bidi-iterating, don't decrement the iterator position;
9336 instead, set the first_elt flag in the bidi iterator, to produce
9338 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9339 (push_display_prop): xassert that we are iterating a buffer.

9809 Random fixes. E.g., (random) never returned negative values.
9810 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9811 subseconds part to the entropy, as that's a bit more random.
9812 Prefer signed to unsigned, since the signedness doesn't matter and
9813 in general we prefer signed. When given a limit, use a
9814 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9815 latter isn't right if USE_2_TAGS_FOR_INTS.
9816 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9817 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9830 This is more efficient than Ffile_directory_p and avoids a minor race.
9832 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9834 * buffer.c (Foverlay_put): Say what the return value is
9837 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9840 (barf_or_query_if_file_exists): Make the "File is a directory"
9841 error be more correct.
9843 * fns.c (Frequire): Remove the mention of the .gz files, since
9844 that's installation-specific, but keep the mention of
9845 `get-load-suffixes'.

9849 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9962 * eval.c (struct backtrace): Simplify and port the data structure.
9963 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9964 signed bit field, as this assumption is not portable and it makes
9965 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9966 "char debug_on_exit : 1" as this is not portable either; instead,
9967 use the portable "unsigned int debug_on_exit : 1". Remove unused
9968 member evalargs. Remove obsolete comments about cc bombing out.

10037 (get_parent_class, emacs_fixed_set_min_size): Remove.
10038 (emacs_fixed_new): Set priv->f to argument.
10039 (emacs_fixed_get_preferred_width)
10040 (emacs_fixed_get_preferred_height): Use min_width/height from
10041 frames size_hint to set minimum and natural (Bug#8919).
10042 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10043 and use min_width/height from frames size_hint to set
10044 min_width/height (Bug#8919).
10046 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
10047 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.
10050 2011-06-26 Eli Zaretskii <eliz@gnu.org>
10052 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
10053 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
10056 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
10058 * process.c (wait_reading_process_output): Bypass select if
10059 waiting for a cell while ignoring keyboard input, and input is
10060 pending. Suggested by Jan Djärv (Bug#8869).
10062 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
10064 Use gnulib's dup2 module instead of rolling our own.
10065 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
10067 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10069 * dispnew.c (scrolling_window): Before scrolling, turn off a
10070 mouse-highlight in the window being scrolled.

10132 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10134 Integer and buffer overflow fixes (Bug#8873).
10136 * print.c (printchar, strout): Check for string overflow.
10137 (PRINTPREPARE, printchar, strout):
10138 Don't set size unless allocation succeeds.
10140 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10141 for sizes. Check for string overflow more accurately.
10142 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10144 * macros.c: Integer and buffer overflow fixes.
10145 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10146 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10147 Use ptrdiff_t, not int, for sizes.
10148 Don't increment bufsize until after realloc succeeds.
10149 Check for size-calculation overflow.
10150 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10152 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10154 * lread.c: Integer overflow fixes.
10155 (read_integer): Radix is now EMACS_INT, not int,
10156 to improve quality of diagnostics for out-of-range radices.
10157 Calculate buffer size correctly for out-of-range radices.
10158 (read1): Check for integer overflow in radices, and in
10159 read-circle numbers.
10160 (read_escape): Avoid int overflow.
10161 (Fload, openp, read_buffer_size, read1)
10162 (substitute_object_recurse, read_vector, read_list, map_obarray):
10163 Use ptrdiff_t, not int, for sizes.

10178 2011-06-22 Leo Liu <sdl.web@gmail.com>
10180 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10181 Move to minibuffer.el.
10183 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10185 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10186 The following patches are for when GLYPH_DEBUG && !XASSERT.
10187 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10188 * dispnew.c (flush_stdout):
10189 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10190 Mark as externally visible.
10191 * dispnew.c (check_window_matrix_pointers): Now static.
10192 * dispnew.c (window_to_frame_vpos):
10193 * xfns.c (unwind_create_frame):
10194 * xterm.c (x_check_font): Remove unused local.
10195 * scroll.c (CHECK_BOUNDS):
10196 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10197 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10198 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10199 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10200 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10202 (debug_method_add): Use va_list and vsprintf rather than relying
10203 on undefined behavior with wrong number of arguments.
10204 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10205 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10206 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10207 since we're not interested in debugging glyphs with old libraries.
10208 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10209 GCC 4.6.0's static checking.
10211 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10213 Integer overflow and signedness fixes (Bug#8873).

10229 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10230 (.bitmaps_last, struct x_output.icon_bitmap):
10231 Use ptrdiff_t, not int, for bitmap indexes.
10232 (x_allocate_bitmap_record): Check for size overflow.
10233 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10235 Use ptrdiff_t, not int, for overlay counts.
10236 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10237 * editfns.c (overlays_around, get_pos_property):
10238 * textprop.c (get_char_property_and_overlay):
10239 * xdisp.c (next_overlay_change, note_mouse_highlight):
10240 * xfaces.c (face_at_buffer_position):
10241 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10242 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10243 (Fnext_overlay_change, Fprevious_overlay_change)
10244 (mouse_face_overlay_overlaps, Foverlays_in):
10245 Use ptrdiff_t, not int, for sizes.
10246 (overlays_at, overlays_in): Check for size-calculation overflow.
10248 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10250 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10251 (x_session_initialize): Do not assume string length fits in int.
10253 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10254 This is unlikely, but can occur if DPI is outlandish.
10256 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10257 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10259 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10260 * xrdb.c (magic_file_p, search_magic_path):
10261 Omit last arg SUFFIX; it was always 0. All callers changed.
10262 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10264 * xfont.c (xfont_match): Avoid need for strlen.
10266 * xfns.c: Don't assume strlen fits in int.
10267 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10269 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10270 not unsigned long, as we prefer signed integers. All callers changed.
10271 Detect integer overflow in repeat count.
10272 (message_dolog): Don't assume print length fits in 39 bytes.
10273 (display_mode_element): Don't assume strlen fits in int.
10275 * termcap.c: Don't assume sizes fit in int and never overflow.
10276 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10277 (gobble_line): Check for size-calculation overflow.
10279 * minibuf.c (Fread_buffer):
10280 * lread.c (intern, intern_c_string):
10281 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

10285 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10287 * font.c: Don't assume string length fits in int.
10288 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10289 Use ptrdiff_t, not int.
10290 (font_intern_prop): Don't assume string length fits in int.
10291 Don't assume integer property fits in fixnum.
10292 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10294 * filelock.c: Fix some buffer overrun and integer overflow issues.
10295 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10296 Reformulate so as not to need the command string.
10297 Invoke gzip -cd rather than gunzip, as it's more portable.
10298 (lock_info_type, lock_file_1, lock_file):
10299 Don't assume pid_t and time_t fit in unsigned long.
10300 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10301 (current_lock_owner): Prefer signed type for sizes.
10302 Use memcpy, not strncpy, where memcpy is what is really wanted.
10303 Don't assume (via atoi) that time_t and pid_t fit in int.
10304 Check for time_t and/or pid_t out of range, e.g., via a network share.
10305 Don't alloca where an auto var works fine.
10307 * fileio.c: Fix some integer overflow issues.
10308 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10309 Don't assume string length fits in int.
10310 (directory_file_name): Don't assume string length fits in long.
10311 (make_temp_name): Don't assume pid fits in int, or that its print
10312 length is less than 20.
10314 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10316 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10318 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10320 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10321 We prefer signed integers, even for size calculations.
10323 * emacs.c: Don't assume string length fits in 'int'.
10324 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10325 (main): Don't invoke strlen when not needed.
10327 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10328 (XD_DEBUG_MESSAGE): Don't waste a byte.
10330 * callproc.c (getenv_internal_1, getenv_internal)
10331 (Fgetenv_internal):
10332 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10334 * lread.c (invalid_syntax): Omit length argument.
10335 All uses changed. This doesn't fix a bug, but it simplifies the
10336 code away from its former Hollerith-constant appearance, and it's
10337 one less 'int' to worry about when looking at integer-overflow issues.
10338 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10340 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10341 This didn't break anything, but it didn't help either.
10342 It's confusing to put a bogus integer in a place where the actual
10343 value does not matter.
10344 (LIST_END_P): Remove unused macro and its bogus comment.
10345 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10347 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10348 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10350 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10351 We prefer signed types, and the value cannot exceed the EMACS_INT
10352 range anyway (because otherwise the length would not be representable).
10353 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10354 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10355 This avoids a GCC warning when WIDE_EMACS_INT.
10357 * indent.c (sane_tab_width): New function.
10358 (current_column, scan_for_column, Findent_to, position_indentation)
10359 (compute_motion): Use it. This is just for clarity.
10360 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10362 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

10365 * composite.c (composition_gstring_put_cache):
10366 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10368 * editfns.c, insdel.c:
10369 Omit unnecessary forward decls, to simplify future changes.
10371 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10373 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10375 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10376 Use much-faster test for byte-length change.
10377 Don't assume string byte-length fits in 'int'.
10378 Check that character arg fits in 'int'.
10379 (mapcar1): Declare byte as byte, for clarity.
10381 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10383 * fns.c (concat): Catch string overflow earlier.
10384 Do not rely on integer wraparound.
10386 * dispextern.h (struct it.overlay_strings_charpos)
10387 (struct it.selective): Now EMACS_INT, not int.
10388 * xdisp.c (forward_to_next_line_start)
10389 (back_to_previous_visible_line_start)
10390 (reseat_at_next_visible_line_start, next_element_from_buffer):
10391 Don't arbitrarily truncate the value of 'selective' to int.
10393 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10395 * composite.c: Don't truncate sizes to 'int'.
10396 (composition_gstring_p, composition_reseat_it)
10397 (composition_adjust_point): Use EMACS_INT, not int.
10398 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10399 not EMACS_UINT, for indexes.
10401 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10403 * buffer.c: Include <verify.h>.
10404 (struct sortvec.priority, struct sortstr.priority):
10405 Now EMACS_INT, not int.
10406 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10407 (struct sortstr.size, record_overlay_string)
10408 (struct sortstrlist.size, struct sortlist.used):
10409 Don't truncate size to int.
10410 (record_overlay_string): Check for size-calculation overflow.
10411 (init_buffer_once): Check at compile-time, not run-time.
10413 2011-06-22 Jim Meyering <meyering@redhat.com>
10415 Don't leak an XBM-image-sized buffer
10416 * image.c (xbm_load): Free the image buffer after using it.
10418 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10421 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10422 that Sun C diagnosed.
10423 * fns.c (secure_hash): Fix pointer signedness issue.
10424 * intervals.c (static_offset_intervals): New function.
10425 (offset_intervals): Use it.
10427 2011-06-21 Leo Liu <sdl.web@gmail.com>
10430 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10433 * fns.c (secure_hash): Rename from crypto_hash_function and change
10434 the first arg to accept symbols.
10435 (Fsecure_hash): New primitive.
10436 (syms_of_fns): New symbols.
10438 2011-06-20 Deniz Dogan <deniz@dogan.se>
10440 * process.c (Fset_process_buffer): Clarify return value in
10443 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10445 * dispnew.c (add_window_display_history): Use BVAR.
10447 * xdisp.c (debug_method_add): Use BVAR.
10448 (check_window_end, dump_glyph_matrix, dump_glyph)
10449 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10451 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10454 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10455 check till after the cache is created in init_frame_faces.
10457 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10459 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10461 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10463 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10464 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10465 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10467 Improve buffer-overflow checking (Bug#8873).
10468 * fileio.c (Finsert_file_contents):
10469 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10470 Remove the old (too-loose) buffer overflow checks.
10471 They weren't needed, since make_gap checks for buffer overflow.
10472 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10473 The old code merely checked for Emacs fixnum overflow, and relied
10474 on undefined (wraparound) behavior. The new code avoids undefined
10475 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10477 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10478 Tune. Don't use wider integers than needed. Don't use alloca.
10479 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10481 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10483 * insdel.c, lisp.h (buffer_overflow): New function.
10484 (insert_from_buffer_1, replace_range, replace_range_2):
10485 * insdel.c (make_gap_larger):
10486 * editfns.c (Finsert_char):
10487 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10489 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10491 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10493 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10495 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10496 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10498 * fileio.c: Don't assume EMACS_INT fits in off_t.
10499 (emacs_lseek): New static function.
10500 (Finsert_file_contents, Fwrite_region): Use it.
10501 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10503 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10505 * fns.c: Don't overflow int when computing a list length.
10506 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10507 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10508 truncation on 64-bit hosts. Check for QUIT every
10509 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10510 faster and is responsive enough.
10511 (Flength): Report an error instead of overflowing an integer.
10512 (Fsafe_length): Return a float if the value is not representable
10513 as a fixnum. This shouldn't happen except in contrived situations.
10514 (Fnthcdr, Fsort): Don't assume list length fits in int.
10515 (Fcopy_sequence): Don't assume vector length fits in int.
10517 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10518 (header_size, word_size): New constants.
10519 (allocate_vectorlike): Don't check size overflow here.
10520 (allocate_vector): Check it here instead, since this is the only
10521 caller of allocate_vectorlike that could cause overflow.
10522 Check that the new vector's length is representable as a fixnum.
10524 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10525 The previous code was bogus. For example, next_almost_prime (32)
10526 returned 39, which is undesirable as it is a multiple of 3; and
10527 next_almost_prime (24) returned 25, which is a multiple of 5 so
10528 why was the code bothering to check for multiples of 7?
10530 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10532 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10534 Variadic C functions now count arguments with ptrdiff_t.
10535 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10536 Back then I didn't know that the Emacs coding style prefers signed int.
10537 Also, in the meantime I found a few more instances where arguments
10538 were being counted with int, which may truncate counts on 64-bit
10539 machines, or EMACS_INT, which may be unnecessarily wide.
10540 * lisp.h (struct Lisp_Subr.function.aMANY)
10541 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10542 Arg counts are now ptrdiff_t, not size_t.
10543 All variadic functions and their callers changed accordingly.
10544 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10545 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10546 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10547 * callint.c (Fcall_interactively): Check arg count for overflow,
10548 to avoid potential buffer overrun. Use signed char, not 'int',
10549 for 'varies' array, so that we needn't bother to check its size
10550 calculation for overflow.
10551 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10552 * eval.c (apply_lambda):
10553 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10554 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10555 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10557 * callint.c (Fcall_interactively): Don't use index var as event count.
10559 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10560 * mem-limits.h (SIZE): Remove; no longer used.
10562 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10564 Remove unnecessary casts.
10565 * xterm.c (x_term_init):
10566 * xfns.c (x_set_border_pixel):
10567 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10568 These aren't needed now that we assume ANSI C.
10570 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10571 It's more likely to cause problems (due to unsigned overflow)
10574 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10576 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10578 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10580 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10582 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10584 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10586 GLYPH_CODE_FACE returns EMACS_INT, not int.
10587 * dispextern.h (merge_faces):
10588 * xfaces.c (merge_faces):
10589 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10590 Don't assume EMACS_INT fits in int.
10592 * character.h (CHAR_VALID_P): Remove unused parameter.
10593 * fontset.c, lisp.h, xdisp.c: All uses changed.
10595 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10597 * fns.c (concat): Minor tuning based on overflow analysis.
10598 This doesn't fix any bugs. Use int to hold character, instead
10599 of constantly refetching from Emacs object. Use XFASTINT, not
10600 XINT, for value known to be a character. Don't bother comparing
10601 a single byte to 0400, as it's always less.
10603 * floatfns.c (Fexpt):
10604 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10606 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10609 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10611 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10612 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10613 incorrectly succeed when S was a string, because 4294967386 was
10614 truncated before it was used.
10616 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10617 Otherwise, an out-of-range integer could cause undefined behavior
10620 * composite.c: Use int, not EMACS_INT, for characters.
10621 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10622 EMACS_INT, for values that are known to be in character range.
10623 This doesn't fix any bugs but is the usual style inside Emacs and
10624 may generate better code on 32-bit machines.
10626 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10627 This is for reasons similar to the recent CHAR_STRING fix.
10628 * charset.c (Fencode_char): Check that character arg is actually
10629 a character. Pass an int to ENCODE_CHAR.
10630 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10631 wider than 'int', as a compile-time check to prevent future regressions
10634 * character.c (char_string): Remove unnecessary casts.
10636 Make sure a 64-bit char is never passed to CHAR_STRING.
10637 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10638 by silently ignoring the top 32 bits, allowing some values
10639 that were far too large to be valid characters.
10640 * character.h: Include <verify.h>.
10641 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10642 arguments are no wider than unsigned, as a compile-time check
10643 to prevent future regressions in this area.
10645 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10646 (Fsubst_char_in_region):
10648 * xdisp.c (decode_mode_spec_coding):
10649 Adjust to CHAR_STRING's new requirement.
10650 * editfns.c (Finsert_char, Fsubst_char_in_region):
10651 * fns.c (concat): Check that character args are actually
10652 characters. Without this test, these functions did the wrong
10653 thing with wildly out-of-range values on 64-bit hosts.
10655 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10656 These casts should not be needed on 32-bit hosts, either.
10657 * keyboard.c (read_char):
10658 * lread.c (Fload): Remove casts to unsigned.
10660 * lisp.h (UNSIGNED_CMP): New macro.
10661 This fixes comparison bugs on 64-bit hosts.
10662 (ASCII_CHAR_P): Use it.
10663 * casefiddle.c (casify_object):
10664 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10665 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10666 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10667 * dispextern.h (FACE_FROM_ID):
10668 * keyboard.c (read_char): Use UNSIGNED_CMP.
10670 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10671 not to EMACS_INT, to avoid GCC warning.
10673 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10675 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10676 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10677 isn't needed on 32-bit machines.
10679 * buffer.c (Fgenerate_new_buffer_name):
10680 Use EMACS_INT for count, not int.
10681 (advance_to_char_boundary): Return EMACS_INT, not int.
10683 * data.c (Qcompiled_function): Now static.
10685 * window.c (window_body_lines): Now static.
10687 * image.c (gif_load): Rename local to avoid shadowing.
10689 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10690 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10691 * alloc.c (make_save_value): Integer argument is now of type
10692 ptrdiff_t, not int.
10693 (mark_object): Use ptrdiff_t, not int.
10694 * lisp.h (pD): New macro.
10695 * print.c (print_object): Use it.
10697 * alloc.c: Use EMACS_INT, not int, to count objects.
10698 (total_conses, total_markers, total_symbols, total_vector_size)
10699 (total_free_conses, total_free_markers, total_free_symbols)
10700 (total_free_floats, total_floats, total_free_intervals)
10701 (total_intervals, total_strings, total_free_strings):
10702 Now EMACS_INT, not int. All uses changed.
10703 (Fgarbage_collect): Compute overall total using a double, so that
10704 integer overflow is less likely to be a problem. Check for overflow
10705 when converting back to an integer.
10706 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10707 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10708 These were 'int' variables that could overflow on 64-bit hosts;
10709 they were never used, so remove them instead of repairing them.
10710 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10711 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10712 Previously, this ceilinged at INT_MAX, but that doesn't work on
10714 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10716 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10717 (allocate_vectorlike): Check for ptrdiff_t overflow.
10718 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10719 when a (possibly-narrower) signed value would do just as well.
10720 We prefer using signed arithmetic, to avoid comparison confusion.
10722 * alloc.c: Catch some string size overflows that we were missing.
10723 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10724 for convenience in STRING_BYTES_MAX.
10725 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10726 The definition here is exact; the one in lisp.h was approximate.
10727 (allocate_string_data): Check for string overflow. This catches
10728 some instances we weren't catching before. Also, it catches
10729 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10730 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10731 and ptrdiff_t and EMACS_INT are both 64 bits.
10733 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10734 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10735 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10737 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10739 * alloc.c (Fmake_string): Check for out-of-range init.
10741 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10743 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10745 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10747 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10748 xg_get_default_scrollbar_width.
10750 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10751 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10752 (style_changed_cb): Call update_theme_scrollbar_width and call
10753 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10754 all frames (Bug#8505).
10755 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10756 Call gtk_window_set_resizable if HAVE_GTK3.
10757 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10758 and height if HAVE_GTK3 (Bug#8505).
10759 (scroll_bar_width_for_theme): New variable.
10760 (update_theme_scrollbar_width): New function.
10761 (xg_get_default_scrollbar_width): Move code to
10762 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10763 (xg_initialize): Call update_theme_scrollbar_width.
10765 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10767 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10769 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10771 * frame.c (make_frame): Call other_buffer_safely instead of
10774 * window.c (temp_output_buffer_show): Call display_buffer with
10775 second argument Vtemp_buffer_show_specifiers and reset latter
10776 immediately after the call.
10777 (Vtemp_buffer_show_specifiers): New variable.
10778 (auto_window_vscroll_p, next_screen_context_lines)
10779 (Vscroll_preserve_screen_position): Remove leading asterisks from
10782 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10784 Fix minor problems found by GCC 4.6.0 static checking.
10785 * buffer.c (Qclone_number): Remove for now, as it's unused.
10786 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10787 (record_buffer): Remove unused local.
10788 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10789 (set_frame_buffer_list): Remove; unused.
10790 * frame.h (other_visible_frames): Remove decl.
10791 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10792 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10793 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10795 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10796 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10797 Define only if HAVE_GPM.
10798 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10799 (update_hints_inhibit): Remove; never set. All uses removed.
10800 * widgetprv.h (emacsFrameClassRec): Remove decl.
10801 * window.c (delete_deletable_window): Now returns void, since it
10802 wasn't returning anything.
10803 (compare_window_configurations): Remove unused locals.
10804 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10805 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10806 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10807 the same widths as pointers. This follows up on the 2011-05-06 patch.
10808 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10809 * xterm.h: Likewise.
10810 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

10815 (LISP_H): Add lib/intprops.h.
10817 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10819 * image.c (gif_load): Add animation frame delay to the metadata.
10820 (syms_of_image): Use DEFSYM. New symbol `delay'.
10822 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10824 * window.c (delete_deletable_window): Re-add.
10825 (Fset_window_configuration): Rewrite to handle dead buffers and
10826 consequently deletable windows.
10827 (window_tree, Fwindow_tree): Remove. Supply functionality in
10829 (compare_window_configurations): Simplify code.
10831 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10833 * image.c (imagemagick_load_image): Fix type mismatch.
10834 (Fimagemagick_types): Likewise.
10836 * window.h (replace_buffer_in_windows): Declare.
10838 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10840 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10841 Qclone_number. Remove external declaration of Qdelete_window.
10842 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10844 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10845 Run Qbuffer_list_update_hook if allowed.
10846 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10847 buffer list implementation.
10848 (other_buffer_safely): New function.
10849 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10850 calls to replace_buffer_in_windows and
10851 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10853 (record_buffer): Inhibit quitting and rewrite using quittable
10854 functions. Run Qbuffer_list_update_hook if allowed.
10855 (Frecord_buffer, Funrecord_buffer): New functions.
10856 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10857 Move switch-to-buffer to window.el.
10858 (bury-buffer): Move to window.el.
10859 (Vbuffer_list_update_hook): New variable.
10861 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10864 * window.h (resize_frame_windows): Move up in code.
10865 (Fwindow_frame): Remove EXFUN.
10866 (replace_buffer_in_all_windows): Remove prototype.
10867 (replace_buffer_in_windows_safely): Add prototype.
10869 * window.c: Declare Qdelete_window static again. Move down
10870 declaration of select_count.
10871 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10872 (Fother_window): Move to window.el.
10873 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10874 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
10875 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
10877 (replace_buffer_in_windows): Implement by calling
10878 Qreplace_buffer_in_windows.
10879 (replace_buffer_in_all_windows): Remove with some functionality
10880 moved into replace_buffer_in_windows_safely.
10881 (replace_buffer_in_windows_safely): New function.
10882 (select_window_norecord, select_frame_norecord): Move in front
10883 of run_window_configuration_change_hook. Remove now obsolete
10885 (Fset_window_buffer): Rewrite doc-string.
10886 Call Qrecord_window_buffer.
10887 (keys_of_window): Move binding for other-window to window.el.
10889 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10891 * dispextern.h (struct image): Replace data member, whose int_val
10892 and ptr_val fields were not used by anything, with a single
10895 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
10896 (gif_clear_image, gif_load, imagemagick_load_image)
10897 (gs_clear_image, gs_load): Callers changed.

11350 (compute_display_string_pos, compute_display_string_end):
11352 (push_it): Accept second argument POSITION, where pop_it should
11353 jump to continue iteration.
11354 (reseat_1): Initialize bidi_it.disp_pos.
11356 * keyboard.c (adjust_point_for_property): Adjust the call to
11357 display_prop_intangible_p to its new signature.

11367 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11369 Malloc failure behavior now depends on size of allocation.
11370 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11371 * lisp.h: Change signatures accordingly.
11372 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11373 All callers changed. (Bug#8762)
11375 * gnutls.c: Use Emacs's memory allocators.
11376 Without this change, the gnutls library would invoke malloc etc.
11377 directly, which causes problems on non-SYNC_INPUT hosts, and which
11378 runs afoul of improving memory_full behavior. (Bug#8761)
11379 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11380 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11381 xfree instead of the default malloc, realloc, free.
11382 (Fgnutls_boot): No need to check for memory allocation failure,
11383 since xmalloc does that for us.
11385 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11386 * category.c (hash_get_category_set):
11387 * ccl.c (ccl_driver):
11388 * charset.c (Fdefine_charset_internal):

11399 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11400 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11401 * image.c (make_image, search_image_cache, lookup_image)
11402 (xpm_put_color_table_h):
11403 * lisp.h (struct Lisp_Hash_Table):
11404 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11405 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11406 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11407 * alloc.c (allocate_vectorlike):
11408 Check for overflow in vector size calculations.
11409 * ccl.c (ccl_driver):
11410 Check for overflow when converting EMACS_INT to int.
11411 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11412 need to be updated by these changes.
11413 * fns.c (make_hash_table, maybe_resize_hash_table):
11414 Check for integer overflow with large hash tables.
11415 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11416 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11417 (SXHASH_REDUCE): New macro.
11418 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11419 Use it instead of discarding useful hash info with large hash values.
11420 (sxhash_float): New function.
11421 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11422 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11423 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11424 Rewrite to use FIXNUM_BITS, as this simplifies things.
11425 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11426 Adjust signatures to match updated version of code.
11427 (consing_since_gc): Now EMACS_INT, since a single hash table can
11428 use more than INT_MAX bytes.
11430 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11432 Make it possible to build with GCC-4.6+ -O2 -flto.
11434 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11436 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11438 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11439 Call minibuffer-inactive-mode.
11441 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11443 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11444 Update dependencies.
11446 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11448 * data.c (init_data): Remove code for UTS, this system is not
11451 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11453 Don't force ./temacs to start in terminal mode.
11455 * frame.c (make_initial_frame): Initialize faces in all cases, not
11456 only when CANNOT_DUMP is defined.
11457 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11459 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11461 * dispnew.c (add_window_display_history): Use const for the string
11462 pointer. Remove declaration, not needed.
11464 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11466 Use 'inline', not 'INLINE'.
11467 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11468 * alloc.c, fontset.c (INLINE): Remove.
11469 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11470 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11471 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11472 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11473 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11475 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11477 Make it possible to run ./temacs.
11479 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11480 syms_of_callproc does the same thing. Remove test for
11481 "initialized", do it in the caller.
11482 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11484 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11486 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11487 (read_minibuf): Use get_minibuffer.
11488 (syms_of_minibuf): Use DEFSYM.
11489 (Qmetadata): New var.
11490 * data.c (Qbuffer): Don't make it static.
11491 (syms_of_data): Use DEFSYM.
11493 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11495 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11496 (CCL_CODE_MIN): New macro.
11498 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11500 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11502 * eval.c (Qdebug): Now static.
11503 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11504 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11505 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11507 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11509 * image.c: Various fixes to ImageMagick code comments.
11510 (Fimagemagick_types): Doc fix.
11512 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11514 Minor fixes prompted by GCC 4.6.0 warnings.
11516 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11518 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11519 (x_clipboard_manager_save_all): Move extern decl to ...
11520 * xterm.h: ... here, so that it can be checked for consistency.
11522 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11524 * xselect.c (x_clipboard_manager_save_frame)
11525 (x_clipboard_manager_save_all): New functions.
11526 (Fx_clipboard_manager_save): Lisp function deleted.
11528 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11529 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11531 * xterm.h: Update prototype.
11533 2011-05-28 William Xu <william.xwl@gmail.com>
11535 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11536 exiting (Bug#8239).
11538 2011-05-28 Jim Meyering <meyering@redhat.com>
11540 Avoid a sign-extension bug in crypto_hash_function.
11541 * fns.c (to_uchar): Define.
11542 (crypto_hash_function): Use it to convert some newly-signed
11543 variables to unsigned, to avoid sign-extension bugs. For example,
11544 without this change, (md5 "truc") would evaluate to
11545 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11546 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11547 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11549 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11551 Integer overflow fixes.
11553 * dbusbind.c: Serial number integer overflow fixes.
11554 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11555 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11556 to hold a serial number that is too large for a fixnum.
11557 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11558 Check for serial numbers out of range. Decode any serial number
11559 that was so large that it became a float. (Bug#8722)
11561 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11562 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11563 Use XFASTINT rather than XUINT when numbers are nonnegative.
11564 (xd_append_arg, Fdbus_method_return_internal):
11565 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11566 arguments, check that Lisp number is nonnegative, rather than
11567 silently wrapping negative numbers around. (Bug#8722)
11568 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11571 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11573 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11575 ccl: Add integer overflow checks.
11576 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11577 (IN_INT_RANGE): New macros.
11578 (ccl_driver): Use them to check for integer overflow when
11579 decoding a CCL program. Many of the new checks are whether XINT (x)
11580 fits in int; it doesn't always, on 64-bit hosts. The new version
11581 doesn't catch all possible integer overflows, but it's an
11582 improvement. (Bug#8719)
11584 * alloc.c (make_event_array): Use XINT, not XUINT.
11585 There's no need for unsigned here.
11587 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11588 This follows up to the 2011-05-06 change that substituted uintptr_t
11589 for EMACS_INT. This case wasn't caught back then.
11591 Rework Fformat to avoid integer overflow issues.
11592 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11593 now (part of C89). Include <verify.h>.
11594 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11595 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11596 (Fformat): Avoid the prepass trying to compute sizes; it was only
11597 approximate and thus did not catch overflow reliably. Instead, walk
11598 through the format just once, formatting and computing sizes as we go,
11599 checking for integer overflow at every step, and allocating a larger
11600 buffer as needed. Keep track separately whether the format is
11601 multibyte. Keep only the most-recently calculated precision, rather
11602 than them all. Record whether each argument has been converted to
11603 string. Use EMACS_INT, not int, for byte and char and arg counts.
11604 Support field widths and precisions larger than INT_MAX. Avoid
11605 sprintf's undefined behavior with conversion specifications such as %#d
11606 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11607 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11608 formatting out-of-range floating point numbers with int
11609 formats. (Bug#8668)
11611 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11613 * data.c: Avoid integer truncation in expressions involving floats.
11614 * data.c: Include <intprops.h>.
11615 (arith_driver): When there's an integer overflow in an expression
11616 involving floating point, convert the integers to floating point
11617 so that the resulting value does not suffer from catastrophic
11618 integer truncation. For example, on a 64-bit host (* 4
11619 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11620 Do not rely on undefined behavior after integer overflow.
11622 merge count_size_as_multibyte, parse_str_to_multibyte
11623 * character.c, character.h (count_size_as_multibyte):
11624 Rename from parse_str_to_multibyte; all uses changed.
11625 Check for integer overflow.
11626 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11627 since it's now a duplicate of the other. This is more of
11628 a character than a buffer op, so better that it's in character.c.
11629 * fns.c, print.c: Adjust to above changes.
11631 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11633 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11635 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11637 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11638 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11639 (x_clipboard_manager_save): Now static.
11640 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11642 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11643 (crypto_hash_function): Now static.
11644 Fix pointer signedness problems. Avoid unnecessary initializations.
11646 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11648 * termhooks.h (Vselection_alist): Make it terminal-local.
11650 * terminal.c (create_terminal): Initialize it.
11652 * xselect.c: Support for clipboard managers.
11653 (Vselection_alist): Move to termhooks.h as terminal-local var.
11654 (LOCAL_SELECTION): New macro.
11655 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11656 (symbol_to_x_atom): Remove gratuitous arg.
11657 (x_handle_selection_request, lisp_data_to_selection_data)
11658 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11659 (x_own_selection, x_get_local_selection, x_convert_selection):
11660 New arg, specifying work frame. Use terminal-local Vselection_alist.
11661 (some_frame_on_display): Delete unused function.
11662 (Fx_own_selection_internal, Fx_get_selection_internal)
11663 (Fx_disown_selection_internal, Fx_selection_owner_p)
11664 (Fx_selection_exists_p): New optional frame arg.
11665 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11666 (x_handle_selection_clear): Don't treat other terminals with the
11667 same keyboard specially. Use the terminal-local Vselection_alist.
11668 (x_clear_frame_selections): Use Frun_hook_with_args.
11670 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11672 * xterm.h: Add support for those atoms.
11674 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11676 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11677 (converted_selections, conversion_fail_tag): New global variables.
11678 (x_selection_request_lisp_error): Free the above.
11679 (x_get_local_selection): Remove unnecessary code.
11680 (x_reply_selection_request): Args changed; handle arbitrary array
11681 of converted selections stored in converted_selections.
11682 Separate the XChangeProperty and SelectionNotify steps.
11683 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11684 (x_convert_selection): New function.
11685 (x_handle_selection_event): Simplify.
11686 (x_get_foreign_selection): Don't ignore incoming requests while
11687 waiting for an answer; this will fail when we implement
11688 SAVE_TARGETS, and seems unnecessary anyway.
11689 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11690 (Vx_sent_selection_functions): Doc fix.
11692 2011-05-26 Leo Liu <sdl.web@gmail.com>
11694 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11696 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

11700 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11701 for fringe update if it has periodic bitmap.
11702 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11703 and fringe_bitmap_periodic_p.
11705 * fringe.c (get_fringe_bitmap_data): New function.
11706 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11707 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11708 row. Mark glyph row for fringe update if periodicity changed.
11710 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11711 for fringe update unless it has periodic bitmap.
11713 2011-05-25 Kenichi Handa <handa@m17n.org>

11731 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11732 Remove macros that are defined and never used.
11733 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11735 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11737 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11738 (Fx_get_selection_internal): Minor cleanup.

11766 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11768 * systime.h (Time): Define only if emacs is defined.
11769 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11770 where the include path doesn't have X11/X.h by default. See
11771 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11773 2011-05-20 Kenichi Handa <handa@m17n.org>
11775 * composite.c (find_automatic_composition): Fix previous change.
11777 2011-05-20 Glenn Morris <rgm@gnu.org>

11786 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11787 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11788 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11789 (lisp): Set the order to that of loadup.el.
11790 (shortlisp): Make it a copy of $lisp.
11791 (SOME_MACHINE_LISP): Remove.
11792 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11793 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11795 2011-05-18 Kenichi Handa <handa@m17n.org>
11797 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11798 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11799 (find_automatic_composition): Mostly rewrite for efficiency.
11801 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11803 * makefile.w32-in: Update dependencies.
11805 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11807 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11808 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11810 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11812 Fix some integer overflow issues, such as string length overflow.
11814 * insdel.c (count_size_as_multibyte): Check for string overflow.
11816 * character.c (lisp_string_width): Check for string overflow.
11817 Use EMACS_INT, not int, for string indexes and lengths; in
11818 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11819 the resulting string length overflows an EMACS_INT; instead,
11820 report a string overflow if no precision given. When checking for
11821 precision exhaustion, use a check that cannot possibly have
11822 integer overflow. (Bug#8675)
11823 * character.h (lisp_string_width): Adjust to new signature.
11825 * alloc.c (string_overflow): New function.
11826 (Fmake_string): Use it. This doesn't change behavior, but saves
11827 a few bytes and will simplify future changes.
11828 * character.c (string_escape_byte8): Likewise.
11829 * lisp.h (string_overflow): New decl.
11831 Fixups, following up to the user-interface timestamp change.
11832 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11833 for UI timestamps, instead of unsigned long.
11834 * msdos.c (mouse_get_pos): Likewise.
11835 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11836 * w32gui.h (Time): Define by including "systime.h" rather than by
11837 declaring it ourselves. (Bug#8664)
11839 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11840 * image.c (clear_image_cache): Likewise.
11842 * term.c (term_mouse_position): Don't assume time_t wraparound.
11844 Be more systematic about user-interface timestamps.
11845 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11846 and sometimes 'EMACS_UINT', to represent these timestamps.
11847 This change causes it to use 'Time' uniformly, as that's what X uses.
11848 This makes the code easier to follow, and makes it easier to catch
11849 integer overflow bugs such as Bug#8664.
11850 * frame.c (Fmouse_position, Fmouse_pixel_position):
11851 Use Time, not unsigned long, for user-interface timestamps.
11852 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11853 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11854 * keyboard.h (last_event_timestamp): Likewise.
11855 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11856 * menu.h (xmenu_show): Likewise.
11857 * term.c (term_mouse_position): Likewise.
11858 * termhooks.h (struct input_event.timestamp): Likewise.
11859 (struct terminal.mouse_position_hook): Likewise.
11860 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11861 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11862 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11863 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11864 what it was before.
11865 * menu.h, termhooks.h: Include "systime.h", for Time.
11867 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11868 Don't assume that the difference between two unsigned long values
11869 can fit into an integer. At this point, we know button_down_time
11870 <= event->timestamp, so the difference must be nonnegative, so
11871 there's no need to cast the result if double-click-time is
11872 nonnegative, as it should be; check that it's nonnegative, just in
11873 case. This bug is triggered when events are more than 2**31 ms
11874 apart (about 25 days). (Bug#8664)
11876 * xselect.c (last_event_timestamp): Remove duplicate decl.
11877 (x_own_selection): Remove needless cast to unsigned long.
11879 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11880 that always fit in int. Use a sentinel instead of a counter, to
11881 avoid a temp and to allay GCC's concerns about possible int overflow.
11882 * frame.h (struct frame): Use int for menu_bar_items_used
11883 instead of EMACS_INT, since it always fits in int.
11885 * menu.c (grow_menu_items): Check for int overflow.
11887 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11889 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11890 Before, the code was not consistent. These values cannot exceed
11891 2**31 - 1 so there's no need to make them unsigned.
11892 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11893 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11894 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11896 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11898 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11899 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11900 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11901 presumably because the widths might not match.
11903 * window.c (size_window): Avoid needless test at loop start.
11905 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11907 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11909 2011-05-12 Drew Adams <drew.adams@oracle.com>
11911 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11913 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11915 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11916 `width' to `bar_area_x' and `bar_area_width', respectively.
11917 (x_scroll_run): Take account of fringe background extension.
11919 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11920 Rename local vars `left' and `width' to `bar_area_x' and
11921 `bar_area_width', respectively.
11922 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11923 background extension.
11925 2011-05-10 Jim Meyering <meyering@redhat.com>
11927 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11929 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11931 * image.c (Finit_image_library): Return t for built-in image types,
11932 like pbm and xbm. (Bug#8640)
11934 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11936 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11938 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11940 * w32console.c (Fset_screen_color): Doc fix.
11941 (Fget_screen_color): New function.
11942 (syms_of_ntterm): Defsubr it.
11944 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11945 unlink the temporary file if Fcall_process didn't create it in the
11947 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11948 child process will be redirected to a file specified with `:file'.
11949 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11950 cue to call_process_cleanup not to close that handle.
11952 2011-05-07 Ben Key <bkey76@gmail.com>
11954 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11955 one of two shell specific rules, either bootstrap-temacs-CMD or
11956 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11957 to the previous implementation of the bootstrap-temacs rule.
11958 The bootstrap-temacs-CMD rule is similar to the previous
11959 implementation of the bootstrap-temacs rule except that it
11960 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11963 These changes, along with some changes to nt/configure.bat,
11964 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11965 earlier fix to add support for --cflags and --ldflags options
11966 that include quotes so that it works whether make uses cmd or
11969 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11971 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11972 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11974 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11975 a string. Handle both cases.
11976 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11977 (Fdbus_register_method): Use Qinvalid_function.
11979 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11981 * makefile.w32-in: Update dependencies.
11982 (LISP_H): Add inttypes.h and stdin.h.
11983 (PROCESS_H): Add unistd.h.
11985 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11987 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11988 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11990 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11992 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11994 * term.c (vfatal): Remove stray call to va_end.
11995 It's not needed and the C Standard doesn't allow it here anyway.
11997 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11998 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12000 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12003 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12005 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12007 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12009 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12011 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12013 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12014 * charset.c (Fdefine_charset_internal): Don't initialize
12015 charset.code_space[15]. The value was garbage, on hosts with
12016 32-bit int (Bug#8600).
12018 * lread.c (read_integer): Be more consistent with string-to-number.
12019 Use string_to_number to do the actual conversion; this avoids
12020 rounding errors and fixes some other screwups. Without this fix,
12021 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12022 (digit_to_number): Move earlier, for benefit of read_integer.
12023 Return -1 if the digit is out of range for the base, -2 if it is
12024 not a digit in any supported base. (Bug#8602)
12026 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12028 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12029 to match comment at start of function. This also removes a
12030 GCC warning about overflow in a 32+64-bit port.
12032 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12034 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12035 Reported by Stefan Monnier in
12036 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12037 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12038 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12040 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12041 (EMACS_UINTPTR): Likewise, with uintptr_t.
12043 * lisp.h: Prefer 64-bit EMACS_INT if available.
12044 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12045 on 32-bit hosts that have 64-bit int, so that they can access
12047 However, temporarily disable this change unless the temporary
12048 symbol WIDE_EMACS_INT is defined.
12050 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12052 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12053 This removes an assumption that EMACS_INT and long are the same
12054 width as pointers. The assumption is true for Emacs porting targets
12055 now, but we want to make other targets possible.
12056 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12057 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12058 In the rest of the code, change types of integers that hold casted
12059 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12060 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12061 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12062 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12063 No need to cast type when ORing.
12064 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12065 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12066 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12067 assume EMACS_INT is the same width as char *.
12068 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12069 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12070 Remove no-longer-needed casts.
12071 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12072 (xg_tool_bar_help_callback, xg_make_tool_item):
12073 Use EMACS_INTPTR to hold an integer
12074 that will be cast to void *; this can avoid a GCC warning
12075 if EMACS_INT is not the same width as void *.
12076 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12077 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12078 (current_message_1, set_message_1):
12079 Use a local to convert to proper width without a cast.
12080 * xmenu.c (dialog_selection_callback): Likewise.
12082 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12083 Also, don't assume VALBITS / RAND_BITS is less than 5,
12084 and don't rely on undefined behavior when shifting a 1 left into
12086 * lisp.h (get_random): Change signature to match.
12088 * lread.c (hash_string): Use size_t, not int, for hash computation.
12089 Normally we prefer signed values; but hashing is special, because
12090 it's better to use unsigned division on hash table sizes so that
12091 the remainder is nonnegative. Also, size_t is the natural width
12092 for hashing into memory. The previous code used 'int', which doesn't
12093 retain enough info to hash well into very large tables.
12094 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12096 * dbusbind.c: Don't possibly lose pointer info when converting.
12097 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12098 Use XPNTR rather than XHASH, so that the high-order bits of
12099 the pointer aren't lost when converting through void *.
12101 * eval.c (Fautoload): Don't double-shift a pointer.
12103 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12105 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12107 * gnutls.c (DEF_GNUTLS_FN):
12108 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12110 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12112 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12115 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12117 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12118 New version that can reserve upto 2GB of heap space.
12120 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12122 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12124 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12126 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12127 `gnutls_certificate_set_x509_key_file'.
12129 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12131 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12132 Update dependencies.
12134 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12136 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12137 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12138 Remove unused parameter `fildes'.
12139 * process.c (read_process_output, send_process): Don't pass it.
12141 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12143 Fix previous change: the library cache is defined in w32.c.
12144 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12145 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12147 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12149 Implement dynamic loading of GnuTLS on Windows.
12151 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12152 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12153 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12156 * gnutls.c (Qgnutls_dll): Define.
12157 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12158 (gnutls_*): Declare function pointers.
12159 (init_gnutls_functions): New function to initialize function pointers.
12160 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12161 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12162 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12163 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12164 (emacs_gnutls_write, emacs_gnutls_read)
12165 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12166 (Fgnutls_available_p): New function.
12167 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12168 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12169 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12171 * image.c: Include w32.h.
12172 (Vimage_type_cache): Delete.
12173 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12174 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12175 (w32_delayed_load): Move to w32.c.
12177 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12179 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12180 (w32_delayed_load): Move from image.c. When loading a library, record
12181 its filename in the :loaded-from property of the library id.
12182 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12183 Initialize and staticpro them.
12184 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12186 * process.c: Include lisp.h before w32.h, not after.
12187 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12188 instead of gnutls_record_check_pending.
12190 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12192 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12194 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12195 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12198 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12200 * xterm.c (x_set_frame_alpha): Do not set property on anything
12201 else than FRAME_X_OUTER_WINDOW (Bug#8608).

12240 rather than `XVECTOR (FOO)->size'.
12242 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12243 inttypes.h, as a gnulib replacement is used if it not available in
12246 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12248 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12249 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12250 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12252 * coding.c (coding_alloc_by_realloc): Error out if destination
12253 will grow beyond MOST_POSITIVE_FIXNUM.
12254 (decode_coding_emacs_mule): Abort if there isn't enough place in
12255 charbuf for the composition carryover bytes. Reserve an extra
12256 space for up to 2 characters produced in a loop.
12257 (decode_coding_iso_2022): Abort if there isn't enough place in
12258 charbuf for the composition carryover bytes.
12260 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12262 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12263 aborting when %lld or %lll format is passed.
12264 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12265 %llo or %llx format is passed. (Bug#8545)
12267 * window.c (window_scroll_line_based): Use a marker instead of
12268 simple variables to record original value of point. (Bug#7952)
12270 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12271 produced by %s or %c overflows available buffer space. (Bug#8545)
12273 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12275 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12276 (SIZE_MAX): Move defn after all includes, as they might #define it.
12278 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12280 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12282 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12284 * keyboard.c (Qdelayed_warnings_hook): Define.
12285 (command_loop_1): Run `delayed-warnings-hook'
12286 if Vdelayed_warnings_list is non-nil.
12287 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12288 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12290 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12292 * doprnt.c (doprnt): Don't return value smaller than the buffer
12293 size if the message was truncated. (Bug#8545).
12295 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12297 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12298 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12300 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12302 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12304 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12306 * makefile.w32-in: Update dependencies.
12308 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12310 Improve `doprnt' and its usage. (Bug#8545)
12311 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12312 `format_end'. Remove support for %l as a conversion specifier.
12313 Don't use xrealloc. Improve diagnostics when the %l size modifier
12314 is used. Update the commentary.
12316 * eval.c (verror): Simplify calculation of size_t.
12318 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12321 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12323 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12326 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12328 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12329 This makes this file independent of the recent pseudovector change.
12331 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12333 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12335 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12336 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12337 Remove unused local.
12338 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12340 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12341 GCC 4.6.0 optimizes based on type-based alias analysis.
12342 For example, if b is of type struct buffer * and v of type struct
12343 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12344 != &v->size, and therefore "v->size = 1; b->size = 2; return
12345 v->size;" must therefore return 1. This assumption is incorrect
12346 for Emacs, since it type-puns struct Lisp_Vector * with many other
12347 types. To fix this problem, this patch adds a new type struct
12348 vectorlike_header that documents the constraints on layout of vectors
12349 and pseudovectors, and helps optimizing compilers not get fooled
12350 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12351 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12352 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12354 (XSETPVECTYPE): Rewrite in terms of new macro.
12355 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12356 This is a bit clearer, and further avoids the possibility of
12357 undesirable aliasing.
12358 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12359 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12360 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12361 since Lisp_Subr is a special case (no "next" field).
12362 (ASIZE): Now uses header.size rather than size.
12363 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12364 to avoid the hassle of writing XVECTOR (foo)->header.size.
12365 (struct vectorlike_header): New type.
12366 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12367 object, to help avoid aliasing.
12368 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12369 (SUBRP): Likewise, since Lisp_Subr is a special case.
12370 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12371 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12372 (struct Lisp_Hash_Table): Combine first two members into a single
12373 struct vectorlike_header member. All uses of "size" and "next" members
12374 changed to be "header.size" and "header.next".
12375 * buffer.h (struct buffer): Likewise.
12376 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12377 * frame.h (struct frame): Likewise.
12378 * process.h (struct Lisp_Process): Likewise.
12379 * termhooks.h (struct terminal): Likewise.
12380 * window.c (struct save_window_data, struct saved_window): Likewise.
12381 * window.h (struct window): Likewise.
12382 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12383 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12384 * buffer.c (init_buffer_once): Likewise.
12385 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12387 * process.c (Fformat_network_address): Use local var for size,
12390 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12392 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12393 * data.c (atof): Remove decl; no longer used or needed.
12394 (digit_to_number): Move to lread.c.
12395 (Fstring_to_number): Use new string_to_number function, to be
12396 consistent with how the Lisp reader treats infinities and NaNs.
12397 Do not assume that floating-point numbers represent EMACS_INT
12398 without losing information; this is not true on most 64-bit hosts.
12399 Avoid double-rounding errors, by insisting on integers when
12400 parsing non-base-10 numbers, as the documentation specifies.
12401 * lisp.h (string_to_number): New decl, replacing ...
12402 (isfloat_string): Remove.
12403 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12404 (read1): Do not accept +. and -. as integers; this
12405 appears to have been a coding error. Similarly, do not accept
12406 strings like +-1e0 as floating point numbers. Do not report
12407 overflow for integer overflows unless the base is not 10 which
12408 means we have no simple and reliable way to continue.
12409 Break out the floating-point parsing into a new
12410 function string_to_number, so that Fstring_to_number parses
12411 floating point numbers consistently with the Lisp reader.
12412 (digit_to_number): Move here from data.c. Make it static inline.
12413 (E_CHAR, EXP_INT): Remove, replacing with ...
12414 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12415 (string_to_number): New function, replacing isfloat_string.
12416 This function checks for valid syntax and produces the resulting
12417 Lisp float number too. Rework it so that string-to-number
12418 no longer mishandles examples like "1.0e+". Use strtoumax,
12419 so that overflow for non-base-10 numbers is reported only when
12420 there's no portable and simple way to convert to floating point.
12422 * textprop.c (set_text_properties_1): Rewrite for clarity,
12423 and to avoid GCC warning about integer overflow.
12425 * intervals.h (struct interval): Use EMACS_INT for members
12426 where EMACS_UINT might cause problems. See
12427 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12428 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12429 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12431 (offset_intervals): Tell GCC not to worry about length overflow
12432 when negating a negative length.
12434 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12435 (overrun_check_free): Likewise.
12437 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12438 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12441 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12442 (gnutls_make_error): Rename local to avoid shadowing.
12443 (gnutls_emacs_global_deinit): ifdef out; not used.
12444 (Fgnutls_boot): Use const for pointer to readonly storage.
12445 Comment out unused local. Fix pointer signedness problems.
12447 * lread.c (openp): Don't stuff size_t into an 'int'.
12448 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12449 about possible signed overflow.
12451 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12452 (GDK_KEY_g): Don't define if already defined.
12453 (xg_prepare_tooltip): Avoid pointer signedness problem.
12454 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12456 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12457 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12459 * xfns.c (Fx_window_property): Simplify a bit,
12460 to make a bit faster and to avoid GCC 4.6.0 warning.
12461 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12463 * fns.c (internal_equal): Don't assume size_t fits in int.
12465 * alloc.c (compact_small_strings): Tighten assertion a little.
12467 Replace pEd with more-general pI, and fix some printf arg casts.
12468 * lisp.h (pI): New macro, generalizing old pEd macro to other
12469 conversion specifiers. For example, use "...%"pI"d..." rather
12470 than "...%"pEd"...".
12471 (pEd): Remove. All uses replaced with similar uses of pI.
12472 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12473 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12474 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12475 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12476 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12477 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12478 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12480 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12481 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12482 * print.c (safe_debug_print, print_object): Likewise.
12483 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12485 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12486 avoiding the 0 flag, which is not portable.
12487 * process.c (Fmake_network_process): Use pI to avoid cast.
12488 * region-cache.c (pp_cache): Likewise.
12489 * xdisp.c (decode_mode_spec): Likewise.
12490 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12491 behavior on 64-bit hosts with printf arg.
12492 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12493 (x_stop_queuing_selection_requests): Likewise.
12494 (x_get_window_property): Don't truncate byte count to an 'int'
12497 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12498 here, since it parses constructs like leading '-' and spaces,
12499 which are not wanted; and it overflows with large numbers.
12500 Instead, simply match F[0-9]+, which is what is wanted anyway.
12502 * alloc.c: Remove unportable assumptions about struct layout.
12503 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12504 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12505 (allocate_vectorlike, make_pure_vector): Use the new macros,
12506 plus offsetof, to remove unportable assumptions about struct layout.
12507 These assumptions hold on all porting targets that I know of, but
12508 they are not guaranteed, they're easy to remove, and removing them
12509 makes further changes easier.
12511 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12512 This doesn't fix a bug but makes the code clearer.
12513 (string_overrun_cookie): Now const. Use initializers that
12514 don't formally overflow signed char, to avoid warnings.
12515 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12516 can cause Emacs to crash when string overrun checking is enabled.
12517 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12518 multiple of sizeof (EMACS_INT); it need not be, if
12519 alignof(EMACS_INT) < sizeof (EMACS_INT).
12520 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12522 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12524 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12526 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12528 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12529 supposed to be handshaking. (Bug#8556)
12530 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12532 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12534 * lisp.h (Qdebug): List symbol.
12535 * eval.c (Qdebug): Restore global linkage.
12536 * keyboard.c (debug-on-event): New variable.
12537 (handle_user_signal): Break into debugger when debug-on-event
12538 matches the current signal symbol.
12540 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12542 * alloc.c (check_sblock, check_string_bytes)
12543 (check_string_free_list): Convert to standard C.
12545 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12547 * w32.c (emacs_gnutls_push): Fix typo.
12549 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12551 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12552 "cast to pointer from integer of different size".
12554 Improve doprnt and its use in verror. (Bug#8545)
12555 * doprnt.c (doprnt): Document the set of format control sequences
12556 supported by the function. Use SAFE_ALLOCA instead of always
12559 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12560 is one byte too soon. Don't use xrealloc; instead xfree and
12563 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12565 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12568 * gnutls.c: Renamed global_initialized to
12569 gnutls_global_initialized. Added internals for the
12570 :verify-hostname-error, :verify-error, and :verify-flags
12571 parameters of `gnutls-boot' and documented those parameters in the
12572 docstring. Start callback support.
12573 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12574 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12575 on error. Return error code.
12576 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12577 (emacs_gnutls_read): Likewise.
12578 (Fgnutls_boot): Return handshake error code.
12579 (emacs_gnutls_handle_error): New function.
12580 (wsaerror_to_errno): Likewise.

12583 (emacs_gnutls_push): Likewise.
12585 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12586 (emacs_gnutls_push): Likewise.
12588 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
12590 * process.c (wait_reading_process_output): Check if GnuTLS
12591 buffered some data internally if no FDs are set for TLS
12594 * makefile.w32-in (OBJ2): Add gnutls.$(O).
12595 (LIBS): Link to USER_LIBS.

12600 * xdisp.c (handle_single_display_spec): Rename the
12601 display_replaced_before_p argument into display_replaced_p, to
12602 make it consistent with the commentary. Fix typos in the
12605 * textprop.c (syms_of_textprop): Remove dead code.

12611 to changes in oldXMenu/XMenu.h from 2011-04-16.
12612 <menu_help_message, prev_menu_help_message>: Constify.
12613 (IT_menu_make_room): menu->help_text is now `const char **';
12616 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
12617 to changes in oldXMenu/XMenu.h from 2011-04-16.
12618 (struct XMenu): Declare `help_text' `const char **'.

12631 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
12634 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
12635 changes in globals.h immediately force recompilation.
12636 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12637 $(CURDIR)/s/ms-w32.h.

12760 * dispextern.h (struct redisplay_interface): Rename param
12761 to avoid shadowing.

12880 ns_descriptor_to_entity that were caused by using free to
12881 deallocate memory blocks that were allocated by xmalloc (via
12882 xstrdup). This caused Emacs to crash when compiled with

12902 (emacs_read, emacs_write): Use it.
12903 * process.c (send_process): Adjust to the new signatures of
12904 emacs_write and emacs_gnutls_write. Do not attempt to store

13107 * fns.c (weak_hash_tables): Now static.
13109 * fileio.c: Make symbols static if they're not exported.
13110 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

13124 * lisp.h (fatal_error_signal_hook): Remove decl.
13125 (fatal_error_signal): Declare only if FLOAT_CATCH_SIGKILL.
13127 * editfns.c: Move a (normally-unused) function to its only use.
13128 * editfns.c, lisp.h (get_operating_system_release): Remove.
13129 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
13130 worth the hassle of breaking this out.
13132 * xterm.c: Make symbols static if they're not exported.
13133 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
13134 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

13234 * lisp.h: Remove these decls.
13236 * buffer.c (buffer_count): Remove unused var.
13238 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

13240 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13241 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13242 exported only to the debugger.

13245 * atimer.h (run_all_atimers): Remove; not exported.
13247 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13248 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13249 was inaccessible from Lisp.
13250 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13251 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13253 alloc.c: Import and export fewer symbols, and remove unused items.
13254 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13256 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13257 it's not optimized away by whole-program optimization.

13259 (catchlist, handlerlist, mark_backtrace):
13260 Declare only if BYTE_MARK_STACK.

13269 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13270 (mark_backtrace): Define only if BYTE_MARK_STACK.
13271 * xdisp.c (message_enable_multibyte): Now static.
13273 Declare Lisp_Object Q* variables to be 'static' if not exported.
13274 This makes it easier for human readers (and static analyzers)
13275 to see whether these variables are used from other modules.
13276 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13277 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13278 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

13286 Remove decls of unexported vars.
13287 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13289 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13291 Make Emacs functions such as Fatom 'static' by default.
13292 This makes it easier for human readers (and static analyzers)
13293 to see whether these functions can be called from other modules.
13294 DEFUN now defines a static function. To make the function external
13295 so that it can be used in other C modules, use the new macro DEFUE.
13296 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13297 (Finit_image_library):
13298 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13299 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13300 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13301 Remove decls, since these functions are now static.
13302 (Funintern, Fget_internal_run_time): New decls, since these functions
13303 were already external.
13305 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13306 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13312 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13313 Mark functions with DEFUE instead of DEFUN,
13314 if they are used in other modules.
13315 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13316 decls for now-static functions.
13317 * buffer.h (Fdelete_overlay): Remove decl.
13318 * callproc.c (Fgetenv_internal): Mark as internal.

13327 * image.c (Finit_image_library): New forward static decl.
13328 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13329 * intervals.h (Fprevious_property_change):
13330 (Fremove_list_of_text_properties): Remove decls.
13331 * keyboard.c (Fthis_command_keys): Remove decl.
13332 (Fcommand_execute): New forward static decl.

13348 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13350 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13353 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13355 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13356 when at ZV. (Bug#8487)
13358 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13360 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13362 * keyboard.c (parse_tool_bar_item): Likewise.
13363 * sound.c (sound_cleanup, alsa_close): Likewise.
13364 * termcap.c (tgetent): Likewise.
13365 * xfns.c (x_default_font_parameter): Likewise.
13366 * xsettings.c (read_and_apply_settings): Likewise.
13368 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13369 (overrun_check_free): Protoize.
13371 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13373 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13374 since callers should never pass a negative size.
13375 Change the signature to match that of plain 'read' and 'write'; see
13376 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13377 * lisp.h: Update prototypes of emacs_write and emacs_read.
13379 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13381 * xdisp.c (redisplay_window): Don't try to determine the character
13382 position of the scroll margin if the window start point w->startp
13383 is outside the buffer's accessible region. (Bug#8468)
13385 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13387 Fix write-region and its subroutines for buffers > 2GB.
13388 * fileio.c (a_write, e_write): Modify declaration of arguments and
13389 local variables to support buffers larger than 2GB.
13390 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13392 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13393 argument, local variables, and return value.
13395 * lisp.h: Update prototypes of emacs_write and emacs_read.
13397 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13399 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13401 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13403 Fix more problems found by GCC 4.6.0's static checks.
13405 * xdisp.c (vmessage): Use a better test for character truncation.
13407 * charset.c (load_charset_map): <, not <=, for optimization,
13408 and to avoid potential problems with integer overflow.
13409 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13410 * casetab.c (set_identity, shuffle): Likewise.
13411 * editfns.c (Fformat): Likewise.
13412 * syntax.c (skip_chars): Likewise.
13414 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13415 This also lets GCC 4.6.0 generate slightly better loop code.
13417 * callint.c (Fcall_interactively): <, not <=, for optimization.
13418 (Fcall_interactively): Count the number of arguments produced,
13419 not the number of arguments given. This is simpler and lets GCC
13420 4.6.0 generate slightly better code.
13422 * ftfont.c: Distingish more carefully between FcChar8 and char.
13423 The previous code passed unsigned char * to a functions like
13424 strlen and xstrcasecmp that expect char *, which does not
13425 conform to the C standard.
13426 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13427 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13428 char * when the C standard requires it.
13430 * keyboard.c (read_char): Remove unused var.
13432 * eval.c: Port to Windows vsnprintf (Bug#8435).
13433 Include <limits.h>.
13434 (SIZE_MAX): Define if the headers do not.
13435 (verror): Do not give up if vsnprintf returns a negative count.
13436 Instead, grow the buffer. This ports to Windows vsnprintf, which
13437 does not conform to C99. Problem reported by Eli Zaretskii.
13438 Also, simplify the allocation scheme, by avoiding the need for
13439 calling realloc, and removing the ALLOCATED variable.
13441 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13443 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13444 But keep the doprint source code for now, as we might revamp it
13445 and use it again (Bug#8435).
13446 * lisp.h (doprnt): Remove.
13447 * Makefile.in (base_obj): Remove doprnt.o.
13448 * deps.mk (doprnt.o): Remove.
13450 error: Print 32- and 64-bit integers portably (Bug#8435).
13451 Without this change, on typical 64-bit hosts error ("...%d...", N)
13452 was used to print both 32- and 64-bit integers N, which relied on
13453 undefined behavior.
13454 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13455 * lisp.h (error, verror): Mark as printf-like functions.
13456 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13457 Report overflow in size calculations when allocating printf buffer.
13458 Do not truncate output string at its first null byte.
13459 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13460 Truncate the output at a character boundary, since vsnprintf does not
13462 * charset.c (check_iso_charset_parameter): Convert internal
13463 character to string before calling 'error', since %c now has the
13465 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13466 overflow when computing char to be passed to 'error'. Do not
13467 pass Lisp_Object to 'error'; pass the integer instead.
13468 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13469 formatted with plain %d.
13471 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13473 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13475 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13477 * xterm.c (x_catch_errors): Remove duplicate declaration.
13479 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13481 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13483 2011-04-10 Jim Meyering <meyering@redhat.com>
13485 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13486 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13487 return ssize_t not "int", and use size_t as the buffer length.
13488 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13489 * gnutls.h: Update declarations.
13490 * process.c (read_process_output): Use ssize_t, to match.
13491 (send_process): Likewise.
13493 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13495 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13497 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13499 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13500 Use unsigned char, to match FcChar8 type definition.
13502 * xterm.c (handle_one_xevent):
13503 * xmenu.c (create_and_show_popup_menu):
13504 * xselect.c (x_decline_selection_request)
13505 (x_reply_selection_request): Avoid type-punned deref of X events.
13507 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13509 Fix some uses of `int' instead of EMACS_INT.
13510 * search.c (string_match_1, fast_string_match)
13511 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13512 (scan_buffer, find_next_newline_no_quit)
13513 (find_before_next_newline, search_command, Freplace_match)
13514 (Fmatch_data): Make some `int' variables be EMACS_INT.
13516 * xdisp.c (display_count_lines): 3rd argument and return value now
13517 EMACS_INT. All callers changed.
13518 (pint2hrstr): Last argument is now EMACS_INT.

13536 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13537 (encode_invocation_designation): Last argument P_NCHARS is now
13539 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13540 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13542 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.

13560 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13562 * keyboard.c (read_char): Call Lisp function help-form-show,
13563 instead of using internal_with_output_to_temp_buffer.
13564 (Qhelp_form_show): New var.
13565 (syms_of_keyboard): Use DEFSYM macro.
13567 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13578 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13580 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13582 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13584 Fix more problems found by GCC 4.6.0's static checks.
13586 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13588 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13590 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13592 * xdisp.c (vmessage): Mark as a printf-like function.
13594 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

13601 to system-supplied API.
13603 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13605 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13606 This avoids several warnings with gcc -Wstrict-overflow.
13607 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13608 directly, rather than having caller test rule sign. This avoids
13609 some unnecessary tests.
13610 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13611 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13612 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13614 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13615 (xfont_open): Avoid unnecessary tests.
13617 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13619 * composite.h, composite.c (composition_gstring_put_cache):
13620 Use EMACS_INT, not int, for length.
13622 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13623 breaking out part of COMPOSITION_DECODE_RULE.
13624 (COMPOSITION_DECODE_RULE): Use it.
13625 * composite.c (get_composition_id): Remove unused local vars,
13626 by using the new macro.
13628 * textprop.c (set_text_properties_1): Change while to do-while,
13629 since the condition is always true at first.
13631 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13632 (interval_deletion_adjustment): Return unsigned value.
13635 * process.c (list_processes_1, create_pty, read_process_output):
13636 (exec_sentinel): Remove vars that were set but not used.
13637 (create_pty): Remove unnecessary "volatile"s.
13638 (Fnetwork_interface_info): Avoid possibility of int overflow.
13639 (read_process_output): Do adaptive read buffering even if carryover.
13640 (read_process_output): Simplify nbytes computation if buffered.

13645 (update_syntax_table): Use unsigned instead of int.
13647 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13648 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.

13651 * print.c (print_error_message): Avoid int overflow.
13653 * font.c (font_list_entities): Redo for clarity,
13654 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13656 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13657 (font_score): Avoid potential overflow in diff calculation.
13659 * fns.c (substring_both): Remove var that is set but not used.
13660 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13662 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13664 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13665 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13666 can always succeed if overflow has undefined behavior.
13668 * search.c (boyer_moore, wordify): Remove vars set but not used.
13669 (wordify): Omit three unnecessary tests.
13671 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13672 All callers changed. This avoids the need for an unused var.
13674 * casefiddle.c (casify_region): Remove var that is set but not used.
13676 * dired.c (file_name_completion): Remove var that is set but not used.
13678 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13680 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13681 (Finsert_file_contents): Remove unnecessary code checking fd.
13683 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13684 Check for integer overflow on size calculations.
13686 * buffer.c (Fprevious_overlay_change): Remove var that is set
13689 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13690 Remove vars that are set but not used.
13691 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13692 (timer_check_2): Mark vars as initialized.
13694 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13696 * image.c (lookup_image): Remove var that is set but not used.
13697 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13699 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13700 that are set but not used.
13702 * xfns.c (make_invisible_cursor): Don't return garbage
13703 if XCreateBitmapFromData fails (Bug#8410).
13705 * xselect.c (x_get_local_selection, x_handle_property_notify):
13706 Remove vars that are set but not used.
13708 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13709 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13711 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13712 Remove var that is set but not used.
13713 (scroll_bar_windows_size): Now size_t, not int.
13714 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13715 Check for overflow.
13717 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13718 (map_tty_color) [!defined MSDOS]: Likewise.
13720 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13722 * coding.c: Remove vars that are set but not used.
13723 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13724 All callers changed.
13725 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13726 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13727 (decode_coding_charset): Remove vars that are set but not used.
13729 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13730 that is set but not used.
13732 * print.c (print_object): Remove var that is set but not used.
13734 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13735 The gnulib version avoids calling malloc in the usual case,
13736 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13737 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13738 * filelock.c (current_lock_owner): Likewise.
13739 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13740 * sysdep.c: Include allocator.h, careadlinkat.h.
13741 (emacs_no_realloc_allocator): New static constant.
13742 (emacs_readlink): New function.
13743 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13744 ../lib/careadlinkat.h.
13746 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13748 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13749 first non-nil return value).
13751 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13753 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13754 if not defined (Bug#8403).
13756 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13758 * xdisp.c (display_count_lines): Remove parameter `start',
13759 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13760 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13761 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13763 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13764 and thereabouts. All callers changed.
13765 (get_per_char_metric): Remove parameter `f', unused since
13766 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13768 2011-04-02 Jim Meyering <meyering@redhat.com>
13770 do not dereference NULL upon failed strdup
13771 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13772 (ns_get_family): Likewise.
13774 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13776 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13778 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13780 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13783 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13785 Add lexical binding.
13787 * window.c (Ftemp_output_buffer_show): New fun.
13788 (Fsave_window_excursion):
13789 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13791 * lread.c (lisp_file_lexically_bound_p): New function.
13792 (Fload): Bind Qlexical_binding.
13793 (readevalloop): Remove `evalfun' arg.
13794 Bind Qinternal_interpreter_environment.
13795 (Feval_buffer): Bind Qlexical_binding.
13796 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13798 (syms_of_lread): Declare `lexical-binding'.
13800 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13802 * keyboard.c (eval_dyn): New fun.
13803 (menu_item_eval_property): Use it.
13805 * image.c (parse_image_spec): Use Ffunctionp.
13807 * fns.c (concat, mapcar1): Accept byte-code-functions.
13809 * eval.c (Fsetq): Handle lexical vars.
13810 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13811 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13812 (FletX, Flet): Obey lexical binding.
13813 (Fcommandp): Handle closures.
13814 (Feval): New `lexical' arg.
13815 (eval_sub): New function extracted from Feval. Use it almost
13816 everywhere where Feval was used. Look up vars in lexical env.
13818 (Ffunctionp): Move from subr.el.
13819 (Ffuncall): Handle closures.
13820 (apply_lambda): Remove `eval_flags'.
13821 (funcall_lambda): Handle closures and new byte-code-functions.
13822 (Fspecial_variable_p): New function.
13823 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13824 but without exporting it to Lisp.
13826 * doc.c (Fdocumentation, store_function_docstring):
13827 * data.c (Finteractive_form): Handle closures.
13829 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13832 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13834 (exec_byte_code): New function extracted from Fbyte_code to handle new
13835 calling convention for byte-code-functions. Add new byte-codes.
13837 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13839 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13841 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13843 * xdisp.c (redisplay_internal): Fix prototype.
13845 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13847 * xdisp.c (SCROLL_LIMIT): New macro.
13848 (try_scrolling): Use it when setting scroll_limit.
13849 Limit scrolling to 100 screen lines.
13850 (redisplay_window): Even when falling back on "recentering",
13851 position point in the window according to scroll-conservatively,
13852 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13854 (try_scrolling): When point is above the window, allow searching
13855 as far as scroll_max, or one screenful, to compute vertical
13856 distance from PT to the scroll margin position. This prevents
13857 try_scrolling from unnecessarily failing when
13858 scroll-conservatively is set to a value slightly larger than the
13859 window height. Clean up the case of PT below the margin at bottom
13860 of window: scroll_max can no longer be INT_MAX. When aggressive
13861 scrolling is in use, don't let point enter the opposite scroll
13862 margin as result of the scroll.
13863 (syms_of_xdisp) <scroll-conservatively>: Document the
13864 threshold of 100 lines for never-recentering scrolling.
13866 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13868 * dispextern.h (move_it_by_lines):
13869 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13870 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13871 (message_log_check_duplicate): Remove parameters `prev_bol' and
13872 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13873 (redisplay_internal): Remove parameter `preserve_echo_area',
13874 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13876 * indent.c (Fvertical_motion):
13877 * window.c (window_scroll_pixel_based, Frecenter):
13878 Don't pass `need_y_p' to `move_it_by_lines'.
13880 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13882 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13883 steal a few bits to be more compact.
13884 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13885 Remove unneeded casts.
13887 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13889 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13891 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13892 binding" message (bug#7967).
13894 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13896 Fix more problems found by GCC 4.6.0's static checks.
13898 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13899 Remove unused local var.
13901 * editfns.c (Fmessage_box): Remove unused local var.
13903 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13904 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13905 Omit unused local vars.
13906 * window.c (shrink_windows): Omit unused local var.
13907 * menu.c (digest_single_submenu): Omit unused local var.
13908 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13909 Omit unused local var.
13911 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13912 Don't assume string length fits in int.
13913 (keyremap_step, read_key_sequence): Use size_t for sizes.
13914 (read_key_sequence): Don't check last_real_key_start redundantly.
13916 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13917 instead of alloca (Bug#8344).
13919 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13920 (Fbacktrace_frame): Don't assume nframes fits in int.
13922 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13924 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13927 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13929 * cm.c (calccost): Turn while-do into do-while, for clarity.
13931 * keyboard.c (syms_of_keyboard): Use the same style as later
13932 in this function when indexing through an array. This also
13933 works around GCC bug 48267.
13935 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13937 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13939 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13940 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13942 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13943 This avoids undefined behavior on integer overflow, and is a bit
13944 more convenient anyway since it is compared to a size_t variable.
13946 Variadic C functions now count arguments with size_t, not int.
13947 This avoids an unnecessary limitation on 64-bit machines, which
13948 caused (substring ...) to crash on large vectors (Bug#8344).
13949 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13950 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13951 All variadic functions and their callers changed accordingly.

13957 (funcall_lambda, mark_backtrace): Likewise.
13958 * fns.c (concat): Likewise.
13959 * frame.c (x_set_frame_parameters): Likewise.
13960 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13961 0 if not found, not -1. All callers changed.
13963 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13964 (stack_copy_size): Now size_t, not int.
13965 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13967 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13969 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13970 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

14171 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14173 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14174 unconditionally since it does the check itself.
14176 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14178 Fix more problems found by GCC 4.5.2's static checks.
14180 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14181 the first time through the loop, since we know p0 < p1 then.
14182 This also avoids a gcc -Wstrict-overflow warning.
14184 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14185 leading to a memory leak, possible in functions like
14186 load_charset_map_from_file that can allocate an unbounded number
14187 of objects (Bug#8318).
14189 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14190 that could (at least in theory) be that large.
14192 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14193 This is less likely to overflow, and avoids undefined behavior if
14194 overflow does occur. All callers changed. Use strtoul to scan
14195 for the unsigned long integer.
14196 (pint2hrstr): Simplify and tune code slightly.

14212 * process.c (Fmake_network_process): Use socklen_t, not int,
14213 where POSIX says socklen_t is required in portable programs.
14214 This fixes a porting bug on hosts like 64-bit HP-UX, where
14215 socklen_t is wider than int (Bug#8277).
14216 (Fmake_network_process, server_accept_connection):
14217 (wait_reading_process_output, read_process_output):
14220 * process.c: Rename or move locals to avoid shadowing.

14232 Include tparam.h instead, since it declares them.
14233 * cm.h (PC): Remove extern decl; tparam.h now does this.
14234 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14235 * terminfo.c: Include tparam.h, to check interfaces.
14236 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14237 (tparam): Adjust signature to match interface in tparam.h;
14238 this removes some undefined behavior. Check that outstring and len
14239 are zero, which they always are with Emacs.
14240 * tparam.h (PC, BC, UP): New extern decls.
14242 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14243 (xftfont_open): Rename locals to avoid shadowing.

14261 (composition_update_it): Mark var as initialized.
14262 (find_automatic_composition): Mark vars as initialized,
14263 with a FIXME (Bug#8290).

14269 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14270 to avoid shadowing.

14282 Fix pointer signedness.
14283 (alsa_choose_format): Remove unused local var.
14284 (wav_play): Initialize a variable to 0, to prevent undefined
14285 behavior (Bug#8278).
14287 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14289 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14291 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14292 clobbering (Bug#8298).
14293 * sysdep.c (sys_subshell): Likewise.
14294 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14296 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14297 This should get cleaned up, so that child_setup has the
14298 same signature on all platforms.
14300 * callproc.c (call_process_cleanup): Now static.
14301 (relocate_fd): Rename locals to avoid shadowing.
14303 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14305 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14306 not to be necessary, and produces flickering.
14308 2011-03-20 Glenn Morris <rgm@gnu.org>
14310 * config.in: Remove file.
14312 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

14357 Define only if needed.
14359 * unexelf.c (unexec): Name an expression,
14360 to avoid gcc -Wbad-function-cast warning.
14361 Use a different way to cause a compilation error if anyone uses
14362 n rather than nn, a way that does not involve shadowing.
14363 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14365 * deps.mk (unexalpha.o): Remove; unused.

14422 * callint.c (quotify_arg, quotify_args): Now static.
14423 (Fcall_interactively): Rename locals to avoid shadowing.
14424 Use const pointer when appropriate.

14430 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14431 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14432 some of which prompt warnings from gcc -Wbad-function-cast.
14433 (Fformat_time_string, Fencode_time, Finsert_char):
14434 (Ftranslate_region_internal, Fformat):
14435 Rename or remove local vars to avoid shadowing.

14461 (GC_STRING_CHARS): Remove; not used.
14462 (Fmemory_limit): Cast sbrk's returned value to char *.
14464 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14465 avoids undefined behavior in theory.
14467 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14469 Use functions, not macros, for up- and down-casing (Bug#8254).
14470 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14471 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14472 to use the following functions instead of these macros.
14473 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14474 EMACS_INT, since callers assume the returned value fits in int.
14475 (upcase1): Likewise, for UPCASE_TABLE.
14476 (uppercasep, lowercasep, upcase): New static inline functions.
14477 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14487 (regex_compile, re_match_2_internal): Mark locals as initialized.
14488 (RETALLOC_IF): Define only if needed.
14489 (WORDCHAR_P): Likewise. This one is never needed, but is used
14490 only in a comment talking about a compiler bug, so put inside
14491 the #if 0 of that comment.
14492 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14493 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14519 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14520 New macros, so that the caller can use some names other than
14521 gcpro1, gcpro2, etc.
14522 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14524 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14525 argument, for consistency with GCPRO2_VAR, etc: it is now the
14526 prefix of the variable, not the variable itself. All uses
14528 * dired.c (directory_files_internal, file_name_completion):
14529 Rename locals to avoid shadowing.
14531 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14532 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14533 dired.c's scmp function, had undefined behavior.
14534 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14535 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14536 * buffer.h: ... to here, because these macros use current_buffer,
14537 and the new implementation with inline functions needs to have
14538 current_buffer in scope now, rather than later when the macros
14540 (downcase, upcase1): New static inline functions.
14541 (DOWNCASE, UPCASE1): Reimplement using these functions.
14542 This avoids undefined behavior in expressions like
14543 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14544 from race conditions in accessing the global variables
14545 case_temp1 and case_temp2.
14546 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14547 * lisp.h (case_temp1, case_temp2): Remove their decls.
14548 * character.h (ASCII_CHAR_P): Move from here ...
14549 * lisp.h: ... to here, so that the inline functions mentioned
14550 above can use them.
14552 * dired.c (directory_files_internal_unwind): Now static.
14554 * fileio.c (file_name_as_directory, directory_file_name):

14557 (file_name_as_directory): Use const pointers when appropriate.
14558 (Fexpand_file_name): Likewise. In particular, newdir might
14559 point at constant storage, so make it a const pointer.
14560 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14561 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14563 (Fset_file_times, Finsert_file_contents, auto_save_error):

14568 to avoid shadowing.
14570 * marker.c (bytepos_to_charpos): Remove; unused.
14572 * lisp.h (verify_bytepos, count_markers): New decls,
14573 so that gcc does not warn that these functions aren't declared.
14575 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14576 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14577 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14578 (copy_text): Remove unused local var.
14580 * filelock.c (within_one_second): Now static.
14581 (lock_file_1): Rename local to avoid shadowing.
14583 * buffer.c (fix_overlays_before): Mark locals as initialized.
14584 (fix_start_end_in_overlays): Likewise. This function should be
14585 simplified by using pointers-to-pointers, but that's a different

14588 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14589 (report_overlay_modification): Rename locals to avoid shadowing.

14592 Fix pointer signedness issue.
14593 (sys_subshell): Mark local as volatile if checking for lint,
14594 to suppress a gcc -Wclobbered warning that does not seem to be right.
14595 (MAXPATHLEN): Define only if needed.
14597 * process.c (serial_open, serial_configure): Move decls from here ...
14598 * systty.h: ... to here, so that they can be checked.
14600 * fns.c (get_random, seed_random): Move extern decls from here ...
14601 * lisp.h: ... to here, so that they can be checked.
14603 * sysdep.c (reset_io): Now static.

14612 (describe_map_tree):
14613 Rename locals to avoid shadowing.

14764 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
