265 * w32.c (init_environment): Change the default values of many
266 environment variables in dflt_envvars[] to NULL, to avoid pushing
267 them into environment when they were not already defined. Remove
268 the code that deletes site-lisp subdirectories from the default
269 value of EMACSLOADPATH, as it is no longer needed.
270 (check_windows_init_file): Now external, not static. Use
271 Vload_path as is, without adding anything, as this function is now
272 called when Vload_path is already set up.
274 * w32.h (check_windows_init_file): Add prototype.
276 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

283 installation tree, as appropriate.
285 * callproc.c (init_callproc_1): Call decode_env_path instead of
286 doing its equivalent by hand.
287 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
288 the code that sets Vexec_path run on MS-Windows.

319 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
320 Remove unnecessary pointer casts.
321 * alloc.c (record_xmalloc): New function.
322 * lisp.h (record_xmalloc): New decl.
323 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
324 more like a function. This is because the pointer cast is not
325 needed. All uses changed.
326 * print.c (print_string, print_error_message): Avoid length recalc.
328 Improve fix for macroexp crash with debugging (Bug#12118).
329 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
330 ARRAY_MARK_FLAG when checking subscripts, because ASET is
331 not supposed to be invoked from the garbage collector.
332 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
333 (gc_aset): New function, which is like ASET but can be

350 headers (most versions of MinGW w32api don't).
351 (get_security_info, create_symbolic_link)
352 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
354 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
355 in the argument file name.

363 with addition of handling of symlinks and support for 'lstat'. If
364 possible, get file's attributes and security information by
365 handle, not by name. Produce S_IFLNK bit for symlinks, when
367 (stat, lstat): New functions, call 'stat_worker'.
368 (symlink, readlink, careadlinkat): Rewritten to create and resolve
369 symlinks when the underlying filesystem supports them.
371 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
373 Fix macroexp crash on Windows with debugging (Bug#12118).
374 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
375 checking subscripts; problem introduced with the recent
376 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
377 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
378 since it's used in non-static inline functions now.
380 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
381 Don't assume buffer size fits in 'int'. Remove unused local.
383 Use C99-style 'extern inline' if available.

402 * dispnew.c (DISPEXTERN_INLINE):
403 * sysdep.c (SYSTIME_INLINE):

407 (INLINE_HEADER_END): New macros.
408 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

430 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
432 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
433 This how ASET and AREF are supposed to work, and makes
434 it easier to think about future improvements. See
435 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
436 * charset.h (set_charset_attr): New function.

928 the fix for 12036 would have avoided some of the problems noted in

930 would have been more obvious.
931 * emacs.c: Do not include <verify.h>; no longer needed.
932 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
933 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
934 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
935 Remove; now done in lisp.h.

940 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
941 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need

951 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
952 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
953 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
954 Adjust to changes in lisp.h and emacs.c, by using
955 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
956 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
957 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
958 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
959 instead of gdb_valbits.

961 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
962 instead of gdb_array_mark_flag.
963 (xboolvector): Get size from $->size, not $->header.size.
964 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
965 (xreload, hook-run, hookpost-run): Remove.

970 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
971 (gdb_USE_LSB_TAG): New enum constants.

974 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
975 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
976 as constants, so they're visible to GDB.

980 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
981 more convenient now. All uses changed.
982 (VALMASK) [USE_LSB_TAG]: Also define in this case.

995 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
997 Use typedef for EMACS_INT, EMACS_UINT.
998 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
999 than macros. This simplifies debugging in the usual case, since
1000 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1001 and it allows expressions involving EMACS_INT casts.
1002 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1004 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

1021 buffer_defaults and buffer_local_symbols (for sanity and safety).
1023 2012-07-24 Eli Zaretskii <eliz@gnu.org>

1054 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1056 Swap buffer text indirection counters in Fbuffer_swap_text.
1057 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1058 This avoids crash reported by Christoph Scholtes at
1059 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1061 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1063 * nsmenu.m (Popdown_data): New struct.

1088 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
1089 as it's limited by the amount of memory, not by INT_MAX.

1833 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1834 which are not functions. All uses rewritten to use:
1835 (make_emacs_time): New function.
1836 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1837 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1838 not functions. All uses rewritten to use the following, respectively:

1840 (add_emacs_time, sub_emacs_time): New functions.
1841 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1867 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1868 * nsterm.m (ns_term_init):
1869 Avoid the need for strncpy, by using build_string or
1870 make_unibyte_string directly. Use dtoastr, not snprintf.
1871 * process.c (Fmake_network_process): Diagnose service names that
1872 are too long, rather than silently truncating them or creating
1873 non-null-terminated names.
1874 (Fnetwork_interface_info): Likewise, for interface names.
1875 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1876 Prefer sprintf to strncat.
1877 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

1903 Optimize pure C strings initialization.
1904 * lisp.h (make_pure_string): Fix prototype.
1905 (build_pure_c_string): New function, defined as static inline. This
1906 provides a better opportunity to optimize away calls to strlen when
1907 the function is called with compile-time constant argument.
1908 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1909 argument, adjust users accordingly. Use build_pure_c_string where
1911 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1912 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1913 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1915 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1917 Avoid calls to strlen in miscellaneous functions.
1918 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

1924 Avoid calls to strlen in path processing functions.
1925 * fileio.c (file_name_as_directory): Add comment. Change to add
1926 srclen argument and return the length of result. Adjust users

1931 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1933 2012-07-10 Glenn Morris <rgm@gnu.org>
1935 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

1940 * s/gnu.h (DATA_START): Move definitions to configure.
1942 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1943 We include usg5-4-common.h, which defines them both.
1945 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1946 O_RDONLY already includes it).
1948 Stop ns builds setting the EMACSLOADPATH environment variable.
1949 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1950 Now it does not set EMACSLOADPATH, just returns the load-path string.
1951 * nsterm.h: Update accordingly.
1952 * lread.c [HAVE_NS]: Include nsterm.h.
1953 (init_lread) [HAVE_NS]: Use ns_load_path.

1956 2012-07-09 Glenn Morris <rgm@gnu.org>
1958 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1959 since the included bsd-common.h does so.
1961 Stop ns builds setting the EMACSPATH environment variable.
1962 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1963 (ns_init_paths): Do not set EMACSPATH.
1964 * nsterm.h (ns_exec_path): Add it.
1965 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1968 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1970 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1972 * process.c (wait_reading_process_output): 'waitchannels' was unset
1973 when read_kbd || !NILP (wait_for_cell); fix this.
1975 Add GCC-style 'const' attribute to functions that can use it.
1976 * character.h (char_resolve_modifier_mask):
1977 * keyboard.h (make_ctrl_char):
1978 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1987 Add decls with ATTRIBUTE_CONST.
1989 Minor improvements to make_formatted_string.
1990 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1991 where int is good enough, as vsprintf returns an int.
1992 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1994 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1996 Use make_formatted_string to avoid double length calculation.
1997 * lisp.h (make_formatted_string): New prototype.
1998 * alloc.c (make_formatted_string): New function.

2021 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2023 Move marker debugging code under MARKER_DEBUG.
2024 * marker.c (MARKER_DEBUG): Move marker debugging code under
2025 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2026 for bootstrap with --enable-checking (~3x slowdown reported
2027 by Juanma Barranquero <lekktu@gmail.com>).
2028 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2030 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2032 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2033 See <http://bugs.gnu.org/11825#29>.
2035 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2037 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2038 has no font, use the frame's font. (Bug#11813)
2039 (display_line): Add commentary about displaying truncation glyphs
2041 (produce_special_glyphs): Move here from term.c.
2043 * term.c (produce_special_glyphs): Move to xdisp.c.
2045 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2048 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2050 * xdisp.c (display_line): Avoid warning about implicit declaration
2053 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2055 * lisp.h: Remove empty conditional.
2057 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2059 * lread.c (load_path_check): Now static.
2061 Fix some minor --with-ns problems found by static checking.
2062 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2063 (x_set_font) [!HAVE_X_WINDOWS]:
2064 * image.c (xpm_load_image) [HAVE_NS]:
2065 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2066 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2067 Remove unused local.
2068 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2069 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2070 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2071 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2072 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2073 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2074 Fix pointer signedness problem.
2075 * xfaces.c (FRAME_X_FONT_TABLE):
2076 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2078 2012-07-07 Glenn Morris <rgm@gnu.org>
2080 * lread.c (load_path_check): New function, split from init_lread.
2081 (init_lread): Reorganize. Motivation:
2082 If EMACSLOADPATH is set, check/warn about that rather than the
2083 defaults, which we are not going to use. Hence we can remove
2084 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2085 Don't warn if site-lisp directories are missing.
2086 If not installed, start from a blank load-path, since
2087 PATH_LOADSEARCH refers to the eventual installation directories.
2089 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2091 Support truncation and continuation glyphs on GUI frames, when
2092 fringes are disabled. (Bug#11832)
2093 * xdisp.c (init_iterator): Get dimensions of truncation and
2094 continuation glyphs even if on GUI frames. Adjust
2095 it->last_visible_x on GUI frames when the left or right fringes,
2096 or both, are absent.
2097 (start_display, move_it_in_display_line_to): Handle the case of a
2098 GUI frame without a fringe to display continuation or truncation
2100 (insert_left_trunc_glyphs): Support GUI frames: make sure
2101 truncation glyphs overwrite enough glyphs from the current line to
2102 have sufficient space in pixels.
2103 (display_line): Support truncation and continuation glyphs on GUI
2104 frames. If some spare pixels are left on the line after inserting
2105 the truncation glyphs, fill that space with a stretch glyph of a
2106 suitably computed width.
2108 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2109 produce_glyphs, to support GUI sessions.
2111 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2113 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2115 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2117 Do not require float-time's arg to fit in time_t (Bug#11825).
2118 This works better on hosts where time_t is unsigned, and where
2119 float-time is applied to the (negative) difference between two times.
2120 * editfns.c (decode_time_components): Last arg is now double *,
2121 not int *, and means to store all the result as a double, without
2122 worrying about whether the seconds part fits in time_t.
2123 All callers changed.
2124 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2125 All callers changed.
2126 (Ffloat_time): Do not fail merely because the specified time falls
2127 outside of time_t range.
2129 2012-07-07 Glenn Morris <rgm@gnu.org>
2131 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
2132 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
2133 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
2135 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2137 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2138 Update dependencies.
2140 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2142 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2144 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
2145 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
2146 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2147 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2148 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2149 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2151 * xfont.c (compare_font_names): Redo to omit the need for casts.
2153 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2155 * xfns.c (Fx_change_window_property): Doc fix.
2156 * w32fns.c (Fx_change_window_property): Doc fix.
2158 * w32fns.c (Fx_window_property): Accept the same arguments as the
2159 X Windows version. Doc fix.
2160 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2162 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2163 Eli Zaretskii <eliz@gnu.org>
2165 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2166 Windows-specific code from nt/config.nt moved here.
2167 Obsolete settings removed.
2169 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2171 * process.c: Avoid unnecessary calls to gettime.
2172 (wait_reading_process_output): Don't get the time of day
2173 when gobbling data immediately and not waiting, as there's no need
2174 for it in that case. This removes a FIXME.
2176 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2178 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2179 is defined (Bug#11768).
2181 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2183 Fix marker debugging code.
2184 * marker.c (byte_char_debug_check): Do not perform the check
2185 if buffer is not multibyte.
2186 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2187 Call byte_char_debug_check with correct arguments.
2189 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2191 Compile marker debugging code only if ENABLE_CHECKING is defined.
2192 * marker.c (byte_char_debug_check, count_markers):
2193 Use only if ENABLE_CHECKING is defined.
2194 (byte_debug_flag): Remove.
2195 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2196 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2198 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2200 Avoid code repetition in marker-related functions.
2201 * marker.c (attach_marker): New function.
2202 (Fset_marker, set_marker_restricted, set_marker_both)
2203 (set_marker_restricted_both): Use it.
2204 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2205 Consistently rename charno to charpos.
2206 (marker_position): Add eassert.
2207 (marker_byte_position): Convert to eassert.
2209 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2211 Simplify list operations in unchain_overlay and unchain_marker.

2219 * lisp.h (build_marker): New prototype.
2220 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
2221 * composite.c (autocmp_chars): Likewise.
2222 * editfns.c (buildmark): Remove.
2223 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2224 (save_restriction_save): Use build_marker.
2225 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2226 * window.c (save_window_save): Likewise.
2228 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2230 Do not use Fdelete_overlay in delete_all_overlays
2231 to avoid redundant calls to unchain_overlay.
2232 * buffer.c (drop_overlay): New function.
2233 (delete_all_overlays, Fdelete_overlay): Use it.
2234 * minibuf.c (get_minibuffer): Fix comment.
2236 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2238 Port to OpenBSD 5.1 amd64.
2239 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2240 This is needed for OpenBSD, and should be harmless on all BSD systems.
2241 Also, include <sys/sysctl.h>, as it should be available on all
2242 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2243 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2244 use p_pid member, not kp_proc.pid.
2246 2012-07-06 Glenn Morris <rgm@gnu.org>
2248 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2250 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2252 More xmalloc and related cleanup.
2253 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2254 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
2255 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
2256 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
2257 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2258 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2259 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2260 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2261 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2263 Omit needless casts involving void * pointers and allocation.
2264 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2265 as the former is more robust if P's type is changed.
2266 Prefer xzalloc to xmalloc + memset 0.
2267 Simplify malloc-or-realloc to realloc.
2268 Don't worry about xmalloc returning a null pointer.
2269 Prefer xstrdup to xmalloc + strcpy.
2270 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2272 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2273 alloca of a constant.
2275 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2277 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2278 hscroll is larger than the line width. Fixes long and futile
2279 looping inside extend_face_to_end_of_line (on a TTY) producing
2280 glyphs that are not needed and thrown away.
2282 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2284 * marker.c (set_marker_restricted_both): Simplify by using

2294 not defined (Bug#11768).
2295 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2296 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2297 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2298 followed by gtk_box_set_homogeneous (Bug#11768).
2299 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2300 (update_theme_scrollbar_width, xg_create_scroll_bar):
2301 Use gtk_scrollbar_new (Bug#11768).
2302 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

2310 * xdisp.c (window_hscroll_limited): New function.
2311 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2312 coordinates when window's hscroll is set to insanely large
2315 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2317 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2318 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2320 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2323 * lisp.h (xzalloc): New prototype. Omit needless casts.
2324 * alloc.c (xzalloc): New function. Omit needless casts.

2378 * fileio.c (time_error_value): Check the right error number.
2379 Problem reported by Troels Nielsen in
2380 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2382 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2384 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2385 This should be fixed in a better way; see Eli Zaretskii in
2386 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2387 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2389 * fileio.c (time_error_value): Rename from special_mtime.
2390 The old name's problems were noted by Eli Zaretskii in
2391 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2393 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2394 This variable's comment says Emacs needs at least one GDB-visible
2395 symbol of type enum pvec_type, to work around GDB problems.
2396 The symbol's value doesn't matter.
2398 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2399 that causes compilation to fail on pre-C99 compilers.
2401 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2403 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2404 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2406 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2408 * buffer.c (init_buffer_once): Fix initialization of
2409 headers for buffer_defaults and buffer_local_symbols.
2410 Reported by Juanma Barranquero <lekktu@gmail.com>.
2412 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2414 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2415 * lisp.h (enum pvec_type): Use fewer bits.
2416 (PSEUDOVECTOR_SIZE_BITS): New constant.
2417 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2418 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2419 change in pvec_type.
2420 (PSEUDOVECTOR_TYPEP): New macro.
2421 (TYPED_PSEUDOVECTORP): Use it.
2422 * fns.c (internal_equal): Adapt code to extract pvectype.
2423 * emacs.c (gdb_pvec_type): Update type.
2424 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2425 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2426 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2427 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2428 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2429 abusing vector->header.next.nbytes.
2430 (live_vector_p): Use PVEC_TYPE.
2431 (mark_object): Adapt code to extract pvectype. Use switch.
2433 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2435 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2436 Tighten new eassert a bit.
2438 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2440 Fix compilation with --enable-gcc-warnings and -O1
2442 * doprnt.c (doprnt): Change type of tem to int, initialize
2443 to avoid compiler warning. Add eassert.
2444 * search.c (simple_search): Initialize match_byte to avoid
2445 compiler warning. Add eassert.
2447 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2449 Avoid weird behavior with large horizontal scrolls.
2450 Without this change, for example, large hscroll values would
2451 mess up Emacs's display on Fedora 15 x86, presumably due to
2452 overflows in int calculations in the display code.
2453 Also, if buffers had long lines, Emacs would freeze.
2454 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2455 (set_window_hscroll): New function, containing the old guts of
2456 Fset_window_hscroll. Return the clipped value.
2457 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2458 This avoids the need to check against PTRDIFF_MAX.
2460 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2462 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2464 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2466 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2468 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2469 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2470 since GCC 4.4.6 issues a bogus warning for them.
2472 Fix bugs in file timestamp newness comparisons.
2473 * fileio.c (Ffile_newer_than_file_p):
2474 * lread.c (Fload): Use full timestamp resolution of files,
2475 not just the 1-second resolution, so that files that are only
2476 slightly newer still count as newer.
2477 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2478 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2480 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2482 * fileio.c: Improve handling of file time marker. (Bug#11852)
2483 (special_mtime): New function.
2484 (Finsert_file_contents, Fverify_visited_file_modtime):
2485 Use it to set special mtime values consistently.
2487 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2489 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2490 marker for non-existing file. (Bug#11852)
2492 2012-07-03 Glenn Morris <rgm@gnu.org>
2494 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2495 and did not make it into globals.h).
2497 2012-07-03 Tom Tromey <tromey@redhat.com>
2499 * window.c (Fset_window_margins, Fset_window_fringes)
2500 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2501 * textprop.c (Fprevious_property_change): No longer static.
2502 * syntax.c (Fsyntax_table_p): No longer static.

2524 * intervals.h: Remove EXFUNs.
2525 * fontset.h: Remove EXFUN.

2530 * w32term.h: Remove EXFUNs.
2531 * window.h: Remove EXFUNs.

2533 * xterm.h: Remove EXFUN.
2535 2012-07-03 Glenn Morris <rgm@gnu.org>
2537 * lisp.h (Frandom): Make it visible to C.
2538 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2539 buffer for invisible buffers. (Bug#1229)
2541 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2543 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2544 values which aren't power of 2.
2545 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2546 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2549 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2551 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2553 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2555 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2557 * alloc.c (allocate_vector_block): Remove redundant
2558 calls to mallopt if DOUG_LEA_MALLOC is defined.
2559 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2560 avoid calls to mallopt if zero_vector is returned.
2562 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2564 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2565 is enabled, avoid dereferencing NULL current_sblock if
2568 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2570 Cleanup basic buffer management.
2571 * buffer.h (struct buffer): Change layout to use generic vector
2572 marking code. Fix some comments. Change type of 'clip_changed'
2573 to bitfield. Remove unused #ifndef old.
2574 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2575 (GET_OVERLAYS_AT): Fix indentation.
2576 (for_each_per_buffer_object_at): New macro.
2577 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2579 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2580 * alloc.c (allocate_buffer): Adjust to match new layout of
2581 struct buffer. Fix comment.
2582 (mark_overlay): New function.

2584 Lisp area of struct buffer.
2585 (mark_object): Use it. Adjust marking of misc objects
2586 and related comments.
2588 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2590 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2591 wrapper that is not needed because the wrapped code is a no-op (zero
2592 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2593 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2595 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2597 * alloc.c (mark_buffer): Simplify. Remove prototype.
2598 (mark_object): Add comment. Reorganize marking of vector-like
2599 objects. Use CHECK_LIVE for all vector-like objects except buffers
2600 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2601 redundant calls to mark_vectorlike for bool vectors.
2603 2012-06-30 Glenn Morris <rgm@gnu.org>
2605 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2607 * epaths.in (PATH_SITELOADSEARCH): New.
2608 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2609 This is rather than relying on --enable-locallisppath elements
2610 having "site-lisp" in their names. (Bug#10208#25, 11658)
2612 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2614 * w32proc.c (sys_select): Accept and ignore one more argument.
2616 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2618 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2619 (pselect) [!MS_DOS]: Redirect to sys_select.
2621 * sysdep.c: Don't include dos.h and dosfns.h.
2623 * process.c (sys_select):
2624 * msdos.c (sys_select): Accept one more argument and ignore it.
2626 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2627 adapt data types and code to that.
2630 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2631 which clashes with the gnulib function of the same name.
2633 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2635 * font.c (font_style_to_value, font_style_symbolic)
2636 (font_prop_validate_style): Add type checks for values in
2639 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2641 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2644 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2646 * xdisp.c (try_window_id): Undo last change.
2648 * w32.c (getwd): Adjust commentary about startup_dir.
2649 (init_environment): Always call sys_access, even in non-MSVC
2650 builds. Don't chdir to the directory of the Emacs executable.
2651 This undoes code from 1997 which was justified by the need to
2652 "avoid conflicts when removing and renaming directories". But its
2653 downside was that every relative file name was being interpreted
2654 relative to the directory of the Emacs executable, which can never
2655 be TRT. In particular, it broke sys_access when called with
2656 relative file names.
2657 (sys_access): Map GetLastError to errno.
2659 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2661 * window.h (struct window): Change type of 'fringes_outside_margins'
2662 to bitfield. Fix comment. Adjust users accordingly.
2663 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2665 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2668 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2670 * gnutls.c (emacs_gnutls_handshake):
2671 Add QUIT to make the loop interruptible.
2673 2012-06-29 Glenn Morris <rgm@gnu.org>
2675 * charset.c (init_charset): Make lack of etc/charsets fatal.
2677 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2679 * editfns.c (region_limit): Fix type mismatch.
2681 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2683 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2684 undefined. Convert from xassert to eassert.
2685 * nsmenu.m: Convert from xassert to eassert.
2686 * nsterm.m: Likewise.
2688 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2690 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2692 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2694 Avoid integer overflow on scroll-left and scroll-right.
2695 * window.c (HSCROLL_MAX): New macro.
2696 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2697 overflow when requested scroll falls outside ptrdiff_t range.
2699 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2701 * window.h (struct window): Change type of 'hscroll',
2702 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2703 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2704 Adjust users accordingly.
2705 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2706 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2707 from EMACS_INT to ptrdiff_t.
2708 (make_window): Omit redundant initialization.
2710 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2712 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2714 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2716 * window.h (struct window): Change type of 'use_time' and
2717 'sequence_number' from Lisp_Object to int.
2718 * frame.c (make_frame): Adjust users accordingly.
2719 * print.c (print_object): Likewise.

2721 (make_window): Likewise.
2723 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2725 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
2726 enabled with --enable-checking=[all,glyphs] configure option.
2727 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2728 adjust comments accordingly.
2729 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be

2849 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2851 Use sprintf return value instead of invoking strlen on result.
2852 In the old days this wasn't portable, since some sprintf
2853 implementations returned char *. But they died out years ago and
2854 Emacs already assumes sprintf returns int.
2855 Similarly for float_to_string.
2856 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2863 * xfns.c (syms_of_xfns):
2864 Use sprintf or float_to_string result to avoid need to call strlen.
2865 * data.c (Fnumber_to_string):
2866 Use make_unibyte_string, since the string must be ASCII.
2867 * lisp.h, print.c (float_to_string): Now returns int length.
2868 * term.c (produce_glyphless_glyph):
2869 Use sprintf result rather than recomputing it.
2871 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2872 * Makefile.in (ALL_CFLAGS):
2873 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
2874 * gmalloc.c, regex.c: Include <config.h> unconditionally.

2879 strcasecmp if available.

2900 * xfns.c (x_window): Remove redundant cast.
2902 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2904 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2905 `const char *' to `char *' to avoid compiler warning.
2907 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2909 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2910 instead of truncating it to 63 (admittedly a generous limit).
2912 * process.c: Fix spelling and caps in comments.

2963 Remove unnecessary forward decls.
2965 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2967 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

2969 * dispnew.c (Fsleep_for, sit_for):
2970 * keyboard.c (kbd_buffer_get_event):
2971 * process.c (Faccept_process_output):
2972 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2973 This improves on the previous patch, which introduced a bug
2974 when time_t is unsigned and as wide as intmax_t.
2975 See <http://bugs.gnu.org/9000#51>.
2977 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2993 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2994 Privately reported by Herbert J. Skuhra.
2995 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2997 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2998 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3000 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3003 last argument of make_unibyte_string.
3005 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
3006 language ID in the event parameters.
3008 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3009 event.code, not the obscure "character set ID".

3032 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
3033 Privately reported by Herbert J. Skuhra.

3040 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3042 Support higher-resolution time stamps (Bug#9000).
3043 The time stamps are only nanosecond-resolution at the C level,
3044 since that's the best that any real-world system supports now.
3045 But they are picosecond-resolution at the Lisp level, as that's
3046 easy, and leaves room for future OS improvements.
3048 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3051 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3052 Don't get current time unless it's needed.
3054 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3055 now provides it if it's absent.
3056 (start_atimer): Port to higher-res time stamps.
3057 Check for time stamp overflow. Don't get current time more
3058 often than is needed.
3060 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3061 Include systime.h, not time.h.
3062 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3064 * dired.c: Include stat-time.h.
3065 (Ffile-attributes): File times now have higher resolution.

3068 (struct image): Timestamp now has higher resolution.
3070 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3071 has at least microseconds now. All uses removed.
3072 (update_frame, update_single_window, update_window, update_frame_1)
3073 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3075 * editfns.c (time_overflow): Now extern.
3076 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3077 (float-time, Fformat_time_string, Fcurrent_time_string)
3078 (Fcurrent_time_zone): Accept and generate higher-resolution

3081 (decode_time_components, lisp_seconds_argument): New functions.
3082 (make_time): Now static.
3083 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3084 Report an error if the time is invalid, rather than having the caller
3087 * fileio.c: Include <stat-time.h>
3088 (Fcopy_file): Copy higher-resolution time stamps.
3089 Prefer to set the time stamp via a file descriptor if that works.

3091 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3092 (Fvisited_file_modtime, Fset_visited_file_modtime):
3093 Support higher-resolution time stamps.
3095 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3097 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3099 * image.c (prepare_image_for_display, clear_image_cache)
3100 (lookup_image): Port to higer-resolution time stamps.
3102 * keyboard.c (start_polling, bind_polling_period):
3103 Check for time stamp overflow.
3104 (read_char, kbd_buffer_get_event, timer_start_idle)
3105 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3106 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3107 Port to higher-resolution time stamps. Do not assume time_t is signed.
3108 (decode_timer): New function. Timers are now vectors of length 9,
3109 not 8, to accommodate the picosecond component.
3110 (timer_check_2): Use it.
3112 * nsterm.m (select_timeout, timeval_subtract): Remove.
3113 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3114 as they're a bit more accurate and handle overflow better.
3115 (ns_select): Change prototype to be compatible with pselect.
3116 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3117 * nsterm.h (ns_select): Adjust prototype.
3119 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3120 us-resolution time stamps.
3121 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3123 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3125 * lisp.h (time_overflow): New decl.
3126 (wait_reading_process_output): First arg is now intmax_t, not int,
3127 to accommodate larger waits.
3129 * process.h (struct Lisp_Process.read_output_delay):
3130 Now counts nanoseconds, not microseconds.
3131 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3133 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3134 (wait_reading_process_output):
3135 Port to ns-resolution time stamps.
3136 (Faccept_process_output, wait_reading_process_output):
3137 Check for time stamp overflow. Do not assume time_t is signed.
3138 (select_wrapper): Remove; we now use pselect.
3139 (Fprocess_attributes): Now generates ns-resolution time stamps.
3141 * sysdep.c: Include utimens.h. Don't include utime.h
3142 or worry about struct utimbuf; gnulib does that for us now.
3143 (gettimeofday): Remove; gnulib provides a substitute.
3144 (make_timeval): New function.
3145 (set_file_times): Now sets ns-resolution time stamps.
3146 New arg FD; all uses changed.
3147 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3148 (system_process_attributes):
3149 Now returns ns-resolution time stamp. All uses changed.
3150 Check for time stamp overflow.
3152 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3153 provides a substitute now.
3155 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3156 since it guarantees struct timespec.
3157 (EMACS_TIME): Now struct timespec, so that we can support
3158 ns-resolution time stamps.
3159 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3160 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3161 (EMACS_USECS): Remove.
3162 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3163 so multiply the arg by 1000 before storing it.
3164 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3166 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3167 Port to ns-resolution time stamps.
3168 (EMACS_TIME_NEG_P): Remove; replaced by....
3169 (EMACS_TIME_SIGN): New macro.
3170 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3171 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

3173 (make_timeval, make_lisp_time, decode_time_components): New decls.
3174 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3175 that it mishandled time_t overflow. You can't compare by subtracting!
3176 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3177 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3179 * term.c: Include <sys/time.h>.
3180 (timeval_to_Time): New function, for proper overflow wraparound.
3181 (term_mouse_position, term_mouse_click): Use it.
3183 * undo.c (record_first_change): Support higher-resolution time stamps
3185 (Fprimitive_undo): Use them when restoring time stamps.
3187 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3188 (w32_get_internal_run_time):
3189 Port to higher-resolution Emacs time stamps.
3190 (ltime): Now accepts single 64-bit integer, as that's more convenient
3193 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3195 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3196 for compatibility with pselect. Support ns-resolution time stamps.
3198 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3200 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3201 Check for time stamp overflow, and support ns-resolution time stamps.
3203 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3204 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3205 (timeval_subtract): Remove; no longer needed.
3206 (XTflash, XTring_bell, x_wait_for_event):
3207 Port to ns-resolution time stamps. Don't assume time_t is signed.
3209 2012-06-22 Chong Yidong <cyd@gnu.org>
3211 * xdisp.c (x_consider_frame_title): Revert last change.
3213 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3215 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3216 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3217 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3218 staticidx goes up to 1597 out of 1600 = 0x640.)
3220 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3222 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3223 Otherwise, the umask might be mistakenly 0 while handling input signals.
3225 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3227 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
3229 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
3231 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
3232 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
3233 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3234 access to `contents' member of Lisp_Vector objects with AREF and ASET
3237 2012-06-19 Chong Yidong <cyd@gnu.org>

3490 code works fine either way, and efficiency is not a concern here,
3491 as the union type is for debugging, not for production.
3492 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3493 Use an inline function on all platforms when using the union type,
3494 since this is simpler and 'static inline' can be used portably

3639 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3640 would mishandle a string argument "Xc" if X was a multibyte

3716 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3717 fields from Lisp_Object to bitfield. Adjust users accordingly.
3719 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3721 Pacify gcc -Wdouble-precision when using Xaw.
3722 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3723 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3724 Use 'float' consistently, rather than 'float' in most places
3725 and 'double' in a couple of places.
3727 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3729 * xdisp.c (handle_stop): Detect whether we have overlay strings
3730 loaded by testing it->current.overlay_string_index to be
3731 non-negative, instead of checking whether n_overlay_strings is
3732 positive. (Bug#11587)
3734 2012-05-31 Chong Yidong <cyd@gnu.org>
3736 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3738 * doc.c (Fsubstitute_command_keys): Doc fix.
3740 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3742 * search.c (search_buffer): Remove calls to
3743 r_alloc_inhibit_buffer_relocation, as it is now called by
3744 maybe_unify_char, which was the cause of relocation of buffer text
3747 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3749 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3750 for the duration of call to load_charset, to avoid problems with
3751 callers of maybe_unify_char that access buffer text through C
3754 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3755 decrement the inhibition flag, instead of just setting or
3758 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3760 Remove obsolete '#define static' cruft.
3761 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3762 This #undef was "temporary" in 2000; it is no longer needed
3763 now that '#define static' has gone away.
3764 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3765 (gray_bitmap_bits): Remove; no longer needed.
3766 All uses replaced with definiens.
3767 * xterm.c: Include "bitmaps/gray.xbm".
3769 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3771 Clean up __executable_start, monstartup when --enable-profiling.
3772 The following changes affect the code only when profiling.
3773 * dispnew.c (__executable_start): Rename from safe_bcopy.
3774 Define only on platforms that need it.
3775 * emacs.c: Include <sys/gmon.h> when profiling.
3776 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3777 (__executable_start): Remove decl, since lisp.h does it now.
3778 (safe_bcopy): Remove decl; no longer has that name.
3779 (main): Coalesce #if into single bit of code, for simplicity.
3780 Cast pointers to uintptr_t, since standard libraries want integers
3782 * lisp.h (__executable_start): New decl.
3784 2012-05-31 Glenn Morris <rgm@gnu.org>
3786 * image.c (Fimagemagick_types): Doc fix.
3788 2012-05-30 Jim Meyering <meyering@redhat.com>
3790 * callproc.c (Fcall_process_region): Include directory component
3791 in mkstemp error message (Bug#11586).
3793 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3795 * alloc.c, lisp.h (make_pure_vector): Now static.
3797 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

3802 * data.c (Fdefalias): Purify definition, except for keymaps.
3803 (Qdefun): Move from eval.c.
3804 * lisp.h (Qdefun): Remove.
3805 * lread.c (read1): Tiny simplification.
3807 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3809 Do not create empty overlays with the evaporate property (Bug#9642).
3810 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3811 Bug#9642, but explicitly check that the buffer the overlay would
3812 be moved to is live and rearrange lines to make sure that errors
3813 will not put the overlay in an inconsistent state.
3814 (Fdelete_overlay): Cosmetics.
3816 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3818 * w32term.c (my_bring_window_to_top): New function.
3819 (x_raise_frame): Use handle returned by DeferWindowPos, which
3820 could be different from the original one.
3821 Call my_bring_window_to_top instead of my_set_foreground_window.
3824 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3825 by calling BringWindowToTop.
3827 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3828 (WM_EMACS_END): Increase by one.
3830 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3832 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3833 This avoids undefined behavior that might cause the eassert
3834 to not catch an out-of-range value.
3836 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3838 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3839 Update dependencies.
3841 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3843 * bidi.c (bidi_mirror_char): Fix last change.
3845 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3847 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3848 when referring to sectname field in printf format.
3850 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3852 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3853 Only r_alloc_inhibit_buffer_relocation needed to be added;
3854 the others were already declared.
3856 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3857 before checking whether it's out of range. Put the check inside
3859 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3861 2012-05-27 Ken Brown <kbrown@cornell.edu>
3863 * callproc.c (Fcall_process): Restore a line that was accidentally
3864 commented out in the 2011-02-13 change (bug#11547).
3866 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3868 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3869 defined on ralloc.c.
3871 * buffer.c [REL_ALLOC]: Remove prototypes of
3872 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3873 they are now on lisp.h.
3875 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3877 * search.c (search_buffer): Use it to inhibit relocation of buffer
3878 text while re_search_2 is doing its job, because re_search_2 is
3879 passed C pointers to buffer text. (Bug#11519)
3881 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3884 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3885 state after an additional call to move_it_in_display_line_to, keep
3886 the values of it->max_ascent and it->max_descent found for the
3888 (pos_visible_p): Revert the comparison against bottom_y to what it
3889 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3892 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3894 Fix coding-related core dumps with gcc -ftrapv.
3895 The code was computing A - B, where A and B are pointers, and B is
3896 random garbage. This can lead to core dumps on platforms that
3897 have special pointer registers, and it also leads to core dumps on
3898 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3899 A - B only when B is initialized properly.
3900 * coding.c (coding_set_source, coding_set_destination): Return void.
3901 (coding_change_source, coding_change_destinations): New functions,
3902 with the old behaviors of coding_set_source and coding_set_destination.
3903 All callers that need an offset changed to use these new functions.
3905 2012-05-26 Glenn Morris <rgm@gnu.org>
3907 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3909 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3911 Extend mouse support on W32 text-mode console.
3912 * xdisp.c (draw_row_with_mouse_face):
3913 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3915 * w32console.c: Include window.h.
3916 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3918 (initialize_w32_display): Initialize mouse-highlight data.
3920 * w32inevt.c: Include termchar.h and window.h.
3921 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3922 moves, call note_mouse_highlight. If help_echo changed, call
3923 gen_help_event to produce help-echo message in the echo area.
3924 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3927 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3929 * lread.c (read1): Simplify slightly to avoid an overflow warning
3930 with GCC 4.7.0 on x86-64.
3932 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3934 * bidi.c (bidi_mirror_char): Revert last change: an int is
3935 definitely wide enough here.
3937 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3939 Fix integer width and related bugs (Bug#9874).
3940 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3941 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3942 (string_bytes, check_sblock, allocate_string_data):

3945 (make_string_from_bytes, make_specified_string)
3946 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3947 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3949 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3950 (allocate_pseudovector):
3951 Use int, not EMACS_INT, where int is wide enough.
3952 (inhibit_garbage_collection, Fgarbage_collect):
3953 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3954 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3955 int might not be wide enough.
3956 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3957 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3958 (bidi_at_paragraph_end, bidi_find_paragraph_start)
3959 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3960 (bidi_level_of_next_char, bidi_move_to_visually_next):
3961 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3962 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3963 (Fkill_buffer, Fset_buffer_major_mode)
3964 (advance_to_char_boundary, Fbuffer_swap_text)
3965 (Fset_buffer_multibyte, overlays_at, overlays_in)
3966 (overlay_touches_p, struct sortvec, record_overlay_string)
3967 (overlay_strings, recenter_overlay_lists)
3968 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3969 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3970 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3971 (Foverlay_recenter, last_overlay_modification_hooks_used)
3972 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3973 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3974 (validate_region): Omit unnecessary test for b <= e,
3975 since that's guaranteed by the previous test.
3976 (adjust_overlays_for_delete): Avoid pos + length overflow.
3977 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3978 (report_overlay_modification):
3979 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3980 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3981 Omit pointer cast, which isn't needed anyway, and doesn't work
3982 after the EMACS_INT -> ptrdiff_t change.
3983 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3984 * buffer.h: Adjust decls to match defn changes elsewhere.
3985 (struct buffer_text, struct buffer):

3987 Use EMACS_INT, not int, where int might not be wide enough.
3988 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3989 not int, to avoid needless 32-bit limit on 64-bit hosts.
3990 (exec_byte_code): Use tighter memory-full test, one that checks
3991 for alloca overflow. Don't compute the address of the object just
3992 before an array, as that's not portable. Use EMACS_INT, not
3993 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3994 * callint.c (Fcall_interactively):
3995 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3996 * callproc.c (call_process_kill, Fcall_process):
3997 Don't assume pid_t fits into an Emacs fixnum.
3998 (call_process_cleanup, Fcall_process, child_setup):

4000 (call_process_cleanup, Fcall_process, delete_temp_file)
4001 (Fcall_process_region):
4002 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4003 (Fcall_process): Simplify handling of volatile integers.
4004 Use int, not EMACS_INT, where int will do.
4005 * casefiddle.c (casify_object, casify_region, operate_on_word)
4006 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4007 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4008 (casify_object): Avoid integer overflow when overallocating buffer.
4009 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4010 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4011 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4012 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4013 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4014 integers are now checked earlier. All uses replaced with XINT.
4016 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4017 For CCL_MapSingle, check that content and value are in int range.
4018 (ccl_driver, Fregister_code_conversion_map):
4019 Check that Vcode_version_map_vector is a vector.
4020 (resolve_symbol_ccl_program): Check that vector header is in range.
4021 Always copy the vector, so that we can check its contents reliably
4022 now rather than having to recheck each instruction as it's being
4023 executed. Check that vector words fit in 'int'.
4024 (ccl_get_compiled_code, Fregister_ccl_program)
4025 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4026 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4027 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4028 contents are in range.
4029 (Fccl_execute_on_string): Check that status is in range.
4030 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4031 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4032 Accept and return EMACS_INT, not int, because callers can pass values
4034 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4035 (multibyte_chars_in_text, parse_str_as_multibyte)
4036 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
4037 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4038 (string_escape_byte8, Fget_byte):
4039 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4040 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4041 avoid mishandling large integers.
4042 * character.h: Adjust decls to match defn changes elsewhere.
4043 * charset.c (load_charset_map_from_file, find_charsets_in_text)
4044 (Ffind_charset_region):
4045 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4046 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
4047 (load_charset_map_from_vector, Fdefine_charset_internal):
4048 Don't assume fixnum fits in int.
4049 (load_charset_map_from_vector, Fmap_charset_chars):
4050 Remove now-unnecessary CHECK_NATNUMs.
4051 (Fdefine_charset_internal): Check ranges here, more carefully.
4052 Don't rely on undefined behavior with signed left shift overflow.
4053 Don't assume unsigned int fits into fixnum, or that fixnum fits
4054 into unsigned int. Don't require max_code to be a valid fixnum;
4055 that's not true for gb10830 4-byte on a 32-bit host. Allow
4056 invalid_code to be a cons, for the same reason. Require code_offset
4057 to be a character. Avoid int overflow if max_char is close
4059 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4060 this is intended anyway and avoids some undefined behavior.
4061 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4062 INDEX_TO_CODE_POINT, as that's what it expects.
4063 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4064 * charset.h (DECODE_CHAR): Return int, not unsigned;
4065 this is what was intended anyway, and it avoids undefined behavior.
4066 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4067 integer-overflow issues.
4068 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4069 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4070 where the argument is EMACS_INT, and this behavior is not intended.
4071 * chartab.c (Fmake_char_table, Fset_char_table_range)
4072 (uniprop_get_decoder, uniprop_get_encoder):
4073 Don't assume fixnum fits in int.
4074 * cmds.c (move_point): New function, that does the gist of
4075 Fforward_char and Fbackward_char, but does so while checking
4076 for integer overflow more accurately.
4077 (Fforward_char, Fbackward_char): Use it.
4078 (Fforward_line, Fend_of_line, internal_self_insert)
4079 (internal_self_insert):
4080 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4081 Fix a FIXME, by checking for integer overflow when calculating
4082 target_clm and actual_clm.

4114 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4115 (consume_chars): Rewrite to not calculate an address outside buffer.
4116 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
4117 Don't access memory outside of the args array.
4118 (Fdefine_coding_system_internal): Check for charset-id overflow.
4119 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4120 result of ENCODE_CHAR.
4121 * coding.h: Adjust decls to match defn changes elsewhere.

4853 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4855 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4857 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4859 * lread.c (init_obarray): Declare Qt and Qnil as special.
4861 2012-05-14 Glenn Morris <rgm@gnu.org>
4863 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4864 Put "libexec" before "bin", for the sake of init_callproc_1.
4866 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4868 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4870 * unexaix.c: Port to more-recent AIX compilers.
4871 (report_error, report_error_1, make_hdr, copy_sym)
4872 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4873 Make arguments const char *, not char *, to avoid violations of C
4874 standard and to fix some AIX warnings reported by Gilles Pion.
4876 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4878 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4879 already have overlays loaded.
4880 (handle_single_display_spec): Before returning without displaying
4881 fringe bitmap, synchronize the bidi iterator with the main display
4882 iterator, by calling iterate_out_of_display_property.
4883 (iterate_out_of_display_property): Detect buffer iteration by
4884 testing that it->string is a Lisp string.
4885 (get_next_display_element): When the current object is exhausted,
4886 and there's something on it->stack, call set_iterator_to_next to
4887 proceed with what's on the stack, instead of returning zero.
4888 (set_iterator_to_next): If called at the end of a Lisp string,
4889 proceed to consider_string_end without incrementing string
4890 position. Don't increment display vector index past the end of
4891 the display vector. (Bug#11417)
4892 (pos_visible_p): Don't report a position visible when move_it_to
4893 stopped at the last line of window, which happens to be scanned
4894 backwards by the bidi iteration. (Bug#11464)
4896 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4898 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4899 and right-margin display specs even if the spec is invalid or we
4900 are on a TTY, and thus unable to display on the fringes.
4901 That's because the text with the property will not be displayed anyway,
4902 so we need to signal to the caller that this is a "replacing"
4903 display spec. This fixes display when the spec is invalid or we
4906 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4908 * unexaix.c (make_hdr): Fix typo in prototype.
4909 This bug broke the build on AIX. Problem reported by Gilles Pion.
4911 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4913 * keyboard.c (kbd_buffer_get_event): Read special events also in
4914 batch mode. (Bug#11415)
4916 2012-05-12 Glenn Morris <rgm@gnu.org>
4918 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4920 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4922 * lisp.mk (lisp): Add newcomment.elc.
4924 2012-05-12 Glenn Morris <rgm@gnu.org>
4926 * Makefile.in (MKDIR_P): New, set by configure.
4927 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4929 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4931 Remove unused function hourglass_started.
4932 * dispextern.h (hourglass_started):
4933 * w32fns.c (hourglass_started):
4934 * xdisp.c (hourglass_started): Remove.
4936 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4938 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4939 Update dependencies.
4941 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4943 * xgselect.c (xg_select): Put maxfds+1 into a var.
4944 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4946 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4948 2012-05-10 Dave Abrahams <dave@boostpro.com>
4950 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4951 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4953 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4955 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4956 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4957 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4958 Initialize xd_registered_buses.
4960 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4962 Untag more efficiently if USE_LSB_TAG.
4963 This is based on a proposal by YAMAMOTO Mitsuharu in
4964 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4965 For an admittedly artificial (nth 8000 longlist) benchmark on
4966 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4967 Emacs's overall text size by 1%.
4968 * lisp.h (XUNTAG): New macro.
4969 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4970 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4971 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4972 * eval.c (Fautoload):
4973 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4974 * frame.h (XFRAME): Use XUNTAG.
4976 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4977 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4978 Remove unportable assumptions about print widths of types like
4980 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4981 intptr_t when converting between pointer and integer, to avoid GCC
4982 warnings about wrong width.
4984 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4986 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4987 stack for each reader_thread, instead of defaulting to 8MB
4988 determined by the linker. This avoids failures in creating
4989 subprocesses on Windows 7, see the discussion in this thread:
4990 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4992 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4994 Fix up display of the *Minibuf-0* buffer in the mini window.
4995 * keyboard.c (read_char): Don't clear the echo area if there's no
4997 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4998 contents of *Minibuf-0*) if there's no message displayed in its stead.
5000 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5002 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5005 2012-05-06 Chong Yidong <cyd@gnu.org>
5007 * lisp.mk (lisp): Update.
5009 2012-05-05 Jim Meyering <meyering@redhat.com>
5011 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5013 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5015 * data.c (PUT_ERROR): New macro.
5016 (syms_of_data): Use it. Add new error type `user-error'.
5017 * undo.c (user_error): New function.
5018 (Fprimitive_undo): Use it.
5019 * print.c (print_error_message): Adjust print style for `user-error'.
5020 * keyboard.c (user_error): New function.
5021 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5023 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5025 Do not limit current-time-string to years 1000..9999.
5026 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5027 (Fcurrent_time_string): Support any year that is supported by the
5028 underlying localtime representation. Don't use asctime, as it
5029 has undefined behavior for years outside the range -999..9999.
5031 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5033 Fix race conditions involving setenv, gmtime, localtime, asctime.
5034 Without this fix, interrupts could mess up code that uses these
5035 nonreentrant functions, since setting TZ invalidates existing
5036 tm_zone or tzname values, and since most of these functions return
5037 pointers to static storage.
5038 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5039 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5040 Grow the critical sections to include not just invoking
5041 localtime/gmtime, but also accessing these functions' results
5042 including their tm_zone values if any, and any related TZ setting.
5043 (format_time_string): Last arg is now struct tm *, not struct tm **,
5044 so that the struct tm is saved in the critical section.
5045 All callers changed. Simplify allocation of initial buffer, partly
5046 motivated by the fact that memory allocation needs to be outside
5047 the critical section.
5049 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5051 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5052 with RESET_INTERVAL.
5054 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5055 Remove duplicated buffer name initialization.
5057 2012-05-02 Jim Meyering <jim@meyering.net>
5059 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5061 * xfns.c (x_window): Use xstrdup (Bug#11375).
5063 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5065 * xdisp.c (pos_visible_p): If already at a newline from the
5066 display string before the 'while' loop, don't walk back the glyphs
5067 from it3.glyph_row. Solves assertion violation when the display
5068 string begins with a newline (egg.el). (Bug#11367)
5070 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5072 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5075 2012-05-01 Glenn Morris <rgm@gnu.org>
5077 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5078 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5079 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5080 All were removed before 23.1.
5082 * dispnew.c: Remove HAVE_LIBNCURSES test;
5083 it is always true on relevant platforms.
5085 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5086 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5088 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5090 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5092 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5093 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5096 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5098 Do not avoid creating empty evaporating overlays (Bug#9642).
5099 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5100 That is, do not delete an evaporating overlay if it becomes
5101 empty after its bounds are adjusted to fit within its buffer.
5102 This fix caused other problems, and I'm reverting it until we get
5103 to the bottom of them.
5105 2012-04-27 Chong Yidong <cyd@gnu.org>
5107 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5109 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5111 * xdisp.c (pos_visible_p): If the window start position is beyond
5112 ZV, start the display from buffer beginning. Prevents assertion
5113 violation in init_iterator when the minibuffer window is scrolled
5116 * window.c (window_scroll_pixel_based): Likewise.
5118 2012-04-27 Chong Yidong <cyd@gnu.org>
5120 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5122 2012-04-27 Glenn Morris <rgm@gnu.org>
5124 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5125 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5127 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5129 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5130 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5132 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5134 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5135 display element, check also the underlying string or buffer
5136 character. (Bug#11341)
5138 * w32menu.c: Include w32heap.h.
5139 (add_menu_item): If the call to AppendMenuW (via
5140 unicode_append_menu) fails, disable Unicode menus only if we are
5141 running on Windows 9X/Me.
5143 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5145 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5146 (xgetint): Add missing shift for LSB tags.
5148 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5150 * keyboard.c (read_char): Don't wipe echo area for select window
5151 events: These might get delayed via `mouse-autoselect-window'
5154 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5156 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5157 manipulation of :loaded-from data.
5159 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5161 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5162 now a cons (bug#11311).
5164 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5166 Do not create empty overlays with the evaporate property (Bug#9642).
5167 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5168 if it becomes empty after its bounds are adjusted to fit within
5169 its buffer. Without this fix, in a nonempty buffer (let ((o
5170 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5171 yields an empty overlay that has the evaporate property, which is
5172 not supposed to happen.
5174 Fix minor GTK3 problems found by static checking.
5175 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5176 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5177 (struct _EmacsFixedClass, emacs_fixed_get_type):
5178 Move decls here from emacsgtkfixed.h, since they needn't be public.

5180 (emacs_fixed_class_init): Omit unused local.
5181 (emacs_fixed_child_type): Remove; unused.

5184 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
5185 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5186 (EMACS_FIXED_GET_CLASS): Remove; unused.
5187 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5189 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5190 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5192 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5194 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5195 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5196 (__malloc_size_t, __malloc_ptrdiff_t):
5197 Remove. All uses removed, replaced by the definiens if needed,
5198 since we can assume C89 or better now.
5199 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5200 (protect_malloc_state, align, get_contiguous_space)
5201 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5207 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5208 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5209 Define using prototypes, not old style.
5210 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5211 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5212 (align): Don't assume that signed integer overflow wraps around.
5213 Omit unused local var.
5214 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5215 (_free_internal_nolock, memalign, mallochook, reallochook):
5216 Omit no-longer-needed casts.
5217 (valloc): Use getpagesize, not __getpagesize.
5218 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
5219 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5221 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5223 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
5225 Move functions from C to Lisp. Make non-blocking method calls
5226 the default. Implement further D-Bus standard interfaces.

5268 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5270 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
5271 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
5272 Do not assume ptrdiff_t is the same width as 'int'.
5274 * alloc.c: Handle unusual debugging option combinations.
5275 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5276 since the two debugging options are incompatible.
5277 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5279 (mem_init, mem_insert, mem_insert_fixup):
5280 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
5281 (NEED_MEM_INSERT): Remove; no longer needed.
5283 2012-04-22 Leo Liu <sdl.web@gmail.com>
5285 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
5287 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5289 * sysdep.c [__FreeBSD__]: Minor cleanups.
5290 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5291 Use Emacs indenting style more consistently. Avoid some casts.
5292 Use 'double' consistently rather than mixing 'float' and 'double'.
5294 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5296 * sysdep.c (list_system_processes, system_process_attributes):
5297 Add implementation for FreeBSD (Bug#5243).
5299 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>
5301 * lisp.mk (lisp): Update.
5303 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
5305 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
5306 It is never used otherwise.

5310 * print.c (print_preprocess): Only check print_depth if print-circle
5312 (print_object): Check for cycles even when print-circle is nil and
5313 print-gensym is t, but only check print_depth if print-circle is nil.
5315 2012-04-20 Chong Yidong <cyd@gnu.org>
5317 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5318 set the status to "failed" and ensure that sentinel is run.

5333 farther than the first row after the header line, if any.
5334 Don't consider the header-line row as "partially visible", even if
5335 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5337 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5372 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5373 New extern decls, to avoid calling undeclared functions.
5374 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5375 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5376 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5377 (NEED_MEM_INSERT): New macro.
5378 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5379 Remove one incorrect comment and fix another.

5393 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5394 Remove decls. This fixes an "It stinks!".
5396 * alloc.c (which_symbols): Fix alignment issue / type clash.
5398 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5400 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5413 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5414 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5415 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5416 * s/netbsd.h, s/sol2-6.h:
5417 Remove definition of GC_MARK_STACK, since the default now works.
5418 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5419 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5420 no longer the default.
5421 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5423 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5425 * lread.c (lisp_file_lexically_bound_p):

5446 2012-04-11 Daniel Colascione <dancol@dancol.org>
5448 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5449 against is gone. It's better to use vfork now so that when Cygwin
5450 gains a new, working vfork, we use it automatically (bug#10398).
5452 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5470 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5472 * w32.c (w32_delayed_load): Record the full path of the library
5473 being loaded (bug#10424).
5475 2012-04-09 Glenn Morris <rgm@gnu.org>
5477 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5478 not just in the obarray, before snarfing them. (Bug#11036)
5480 * Makefile.in ($(leimdir)/leim-list.el):
5481 Pass EMACS rather than BUILT_EMACS.

5490 Add convenience `GNUTLS_LOG2i' macro.
5492 * gnutls.c (gnutls_log_function2i): Convenience log function.
5493 (emacs_gnutls_read): Use new log functions,
5494 `gnutls_handshakes_tried' process member, and

5505 * minibuf.c (Fread_variable): Callers changed.
5507 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5509 * xdisp.c (set_cursor_from_row): If the display string appears in
5510 the buffer at position that is closer to point than the position
5511 after the display string, display the cursor on the first glyph of
5512 the display string. Fixes cursor display when a 'display' text
5513 property immediately follows invisible text. (Bug#11094)
5515 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5517 composite.c: use 'double' consistently
5518 * composite.c (get_composition_id): Use 'double' consistently
5519 instead of converting 'float' to 'double' and vice versa; this is
5520 easier to understand and avoids a GCC warning.
5522 2012-04-09 Glenn Morris <rgm@gnu.org>
5524 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5525 preparation for dumping it with emacs. (Bug#4789)

5547 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5548 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5549 objects, as mark_maybe_pointer will catch them otherwise.
5550 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5551 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5553 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5555 Fix typo that broke non-Windows builds.
5556 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5566 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5567 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5568 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5569 [!WINDOWSNT]: New macros.
5570 (init_libxml2_functions, libxml2_loaded_p): New functions.
5571 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5572 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5573 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5574 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5576 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5577 Call init_libxml2_functions before calling libxml2 functions.
5578 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5580 * emacs.c: Don't include libxml/parser.h.
5581 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5582 xmlCleanupParser directly.
5584 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5586 2012-04-07 Eli Zaretskii <eliz@gnu.org>

5594 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5595 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5596 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5597 macros related to unification of CJK characters. For the details,
5598 see the discussion following the message here:
5599 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5601 2012-04-04 Chong Yidong <cyd@gnu.org>
5603 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5605 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5607 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

5615 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5617 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5618 position we get to after a call to move_it_to fails the
5619 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5620 only if we wind up in a string from display property. (Bug#11063)
5622 * window.c (Fdelete_other_windows_internal): Invalidate the row
5623 and column information about mouse highlight, so that redisplay
5624 restores it after reallocating the glyph matrices. (Bug#7464)
5626 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5627 string comes from a `display' text property, use the buffer
5628 position of that property as if we actually saw that position in
5630 (move_it_by_lines): Remove the assertion that
5631 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5632 violated when there's a before-string at the beginning of a line.
5635 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5637 * xdisp.c (append_space_for_newline): If the default face was
5638 remapped, use the remapped face for the appended newline.
5639 (extend_face_to_end_of_line): Use the remapped default face for
5640 extending the face to the end of the line.
5641 (display_line): Call extend_face_to_end_of_line when the default
5642 face was remapped. (Bug#11068)
5644 2012-03-29 Eli Zaretskii <eliz@gnu.org>

5668 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5670 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5672 2012-03-25 Kenichi Handa <handa@m17n.org>
5674 * dispextern.h (struct glyph): Change the bit length of
5675 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5677 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5679 * s/ms-w32.h (tzname): Include time.h before redirecting to
5680 _tzname. Fixes the MSVC build. (Bug#9960)

5684 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5687 * xterm.c (XTread_socket): Only modify handling_signal if
5688 !SYNC_INPUT. (Bug#11080)
5690 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5692 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5693 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5694 when fetching a multibyte character consumes more bytes than
5695 CHAR_BYTES returns, due to unification of CJK characters in
5696 string_char. (Bug#11073)
5698 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5700 * process.c (wait_reading_process_output): Handle pty disconnect
5701 by refraining from sending oneself a SIGCHLD (bug#10933).

5712 2012-03-21 Chong Yidong <cyd@gnu.org>
5714 * xfaces.c (Vface_remapping_alist): Doc fix.
5716 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5718 * w32proc.c (Fw32_set_console_codepage)
5719 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5730 it fit in a valid range (Bug#11003).
5732 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5734 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5735 that is not from display property, accept the row as a "cursor
5736 row" if one of the string's character has a non-nil `cursor'
5737 property. Fixes cursor positioning when there are newlines in
5738 overlay strings, e.g. in icomplete.el. (Bug#11035)
5740 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5742 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

5746 * eval.c (inhibit_lisp_code): Rename from
5747 inhibit_window_configuration_change_hook; move from window.c.
5749 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5750 * window.c (run_window_configuration_change_hook)
5751 (syms_of_window): Callers changed.
5753 2012-03-11 Chong Yidong <cyd@gnu.org>
5755 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5757 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5759 2012-03-10 Chong Yidong <cyd@gnu.org>

5762 is visible (Bug#10955).
5764 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5766 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5768 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5770 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5771 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5774 2012-03-03 Glenn Morris <rgm@gnu.org>
5776 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5778 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5780 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5781 position past the first glyph_row that ends at ZV. (Bug#10902)
5782 (redisplay_window, next_element_from_string): Fix typos in
5784 (redisplay_window): Pass to move_it_vertically the margin in
5785 pixels, not in screen lines.

5789 * buffer.c (buffer-list-update-hook): Doc fix.
5791 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5793 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5794 push_it before setting up the iterator for the first overlay
5795 string, even if we have an empty string loaded.
5796 (next_overlay_string): If there's an empty string on the iterator
5797 stack, pop the stack. (Bug#10903)
5799 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5801 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5802 Suggested by Stefan Monnier in
5803 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5804 * alloc.c (widen_to_Lisp_Object): New static function.
5805 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5806 and widening them to Lisp_Objects. This would work even if
5807 USE_LSB_TAG is defined and wide integers are used, which might
5808 happen in a future version of Emacs.
5810 2012-02-25 Chong Yidong <cyd@gnu.org>
5812 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5815 * xselect.c (Fx_selection_exists_p): Doc fix.
5816 (x_clipboard_manager_save_all): Print an informative message
5817 before saving to clipboard manager.
5819 2012-02-24 Chong Yidong <cyd@gnu.org>
5821 * keyboard.c (process_special_events): Handle all X selection
5822 requests in kbd_buffer, not just the next one (Bug#8869).
5824 2012-02-23 Chong Yidong <cyd@gnu.org>
5826 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5827 call when setting menu-bar-lines and tool-bar-lines parameters.
5828 (unwind_create_frame_1): New helper function.
5830 * window.c (inhibit_window_configuration_change_hook): New var.
5831 (run_window_configuration_change_hook): Obey it.
5832 (syms_of_window): Initialize it.
5834 2012-02-22 Chong Yidong <cyd@gnu.org>
5836 * xterm.c (x_draw_image_relief): Add missing type check for

5849 when computing $valmask.
5851 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5852 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5853 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5854 It's useless in that case, and it can cause problems on hosts
5855 that allocate halves of EMACS_INT values separately.
5856 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5857 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5858 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5859 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5860 it avoids undefined behavior on hosts where shifting right by more
5861 than the word width has undefined behavior.
5863 2012-02-19 Chong Yidong <cyd@gnu.org>
5865 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5866 (Funhandled_file_name_directory, Ffile_name_as_directory)

5887 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

5906 as that creates a dangerous corner case.
5908 * window.c (Fdelete_window_internal): Invalidate the mouse
5909 highlight (Bug#9904).
5911 2012-02-12 Glenn Morris <rgm@gnu.org>

5941 2012-02-07 Chong Yidong <cyd@gnu.org>
5943 * buffer.c (Fbuffer_local_variables)
5944 (buffer_lisp_local_variables): Handle unbound vars correctly;
5945 don't let Qunbound leak into Lisp.
5947 2012-02-07 Glenn Morris <rgm@gnu.org>
5949 * image.c (Fimagemagick_types): Doc fix.
5951 * image.c (imagemagick-render-type): Change it from a lisp object

5984 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5986 Handle overflow when computing char display width (Bug#9496).
5987 * character.c (char_width): Return EMACS_INT, not int.
5988 (char_width, c_string_width): Check for overflow when
5989 computing the width; this is possible now that individual
5990 characters can have unbounded width. Problem introduced
5991 by merge from Emacs 23 on 2012-01-19.
5993 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

6663 behave as if the cursor position were at the window margin.
6665 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6666 and the cursor position is out of bounds, behave as if the cursor

6697 * dispnew.c (verify_row_hash): Call row_hash for computing the
6698 hash code of a row, instead of duplicating code from xdisp.c.
6700 * dispextern.h (row_hash): Add prototype.
6702 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

6807 Avoid some portability problems by eschewing 'extern inline' functions.
6808 The trivial performance wins aren't worth the portability hassles; see
6809 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6811 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6859 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6860 This is also needed for porting to any host where GC_MARK_STACK is
6861 not GC_MAKE_GCPROS_NOOPS.
6862 (which_symbols): Use it.
6864 2011-11-07 Kenichi Handa <handa@m17n.org>

6885 (window_box_width, window_box_left, window_box_left_offset)
6886 (window_box_right, window_box_right_offset): Declare extern.
6887 Otherwise, these inline functions do not conform to C99 and
6888 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6889 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6890 * intervals.c (adjust_intervals_for_insertion)
6891 (adjust_intervals_for_deletion): Now extern, because otherwise the
6892 extern inline functions 'offset_intervals' couldn't refer to it.
6893 (static_offset_intervals): Remove.
6894 (offset_intervals): Rewrite using the old contents of
6895 static_offset_intervals. The old version didn't conform to C99
6896 because an extern inline function contained a reference to an
6897 identifier with static linkage.

6919 (Fwindow_vscroll): Doc fix.
6920 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6921 argument, since it makes no sense to pass a live window and for

7068 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7069 so that this new function doesn't get optimized away by a

7209 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7210 * editfns.c: Rewrite current-time-zone so that it invokes
7211 the equivalent of (format-time-string "%Z") to get the time zone name.
7212 This fixes a bug when the time zone name contains characters that
7213 need converting from the system time locale to Emacs internal format.
7214 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7215 that patch fixed format-time-string to do the conversion, but
7216 I forgot to fix current-time-zone.
7217 (format_time_string): New function, containing most of
7218 what Fformat_time_string used to contain.
7219 (Fformat_time_string): Rewrite in terms of format_time_string.

7226 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7228 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7230 * xdisp.c (start_display): If the character at POS is displayed
7231 via a display vector, reset IT->current.dpvec_index to zero.
7232 (try_window_reusing_current_matrix): If a line ends in a display
7233 vector or the next line starts in a display vector, continue
7234 redrawing the window even though the character position of
7235 start_row was reached.

7240 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7241 with nobreak-char-display too.
7243 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7245 Fix part 3 of bug#9771.
7246 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7247 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7248 non-neutral characters if the current character is a paragraph
7249 separator (a.k.a. Newline). This avoids running the same
7250 expensive loop twice, once when we consume the preceding newline
7251 and the other time when the line actually needs to be displayed.
7252 Avoid the loop when we see neutrals on the base embedding level
7253 following a character whose directionality is the same as the
7254 paragraph's. This avoids running the expensive loop when a line
7255 ends in a long sequence of neutrals, like control characters.
7256 Add assertion against STRONG_AL type. Slightly rearrange code
7257 that determines the type of a neutral given the first non-neutral
7259 (bidi_level_of_next_char): Set next_en_pos to zero when
7260 invalidating its info.
7262 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7264 * xdisp.c (push_display_prop): Determine whether to record string
7265 or buffer position by IT->string, not by IT->method. Allow
7266 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7267 (move_it_vertically_backward): Don't look for character position
7268 immediately after the newline when in a continuation line.
7271 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7273 * window.c (coordinates_in_window): Rewrite and delabelize
7274 vertical border check. (Bug#5357) (Bug#9618)
7276 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7278 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7279 errors in XSetWindowBorder (bug#9310).
7281 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7283 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7284 avoid crash when xmalloc overrun checking is enabled.
7286 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7288 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7289 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7290 cursor motion with <left> and <right> arrow keys.
7292 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7293 some callers set that themselves.
7295 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7297 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7298 display string and the previous row comes from the same string and
7299 is empty. (Bug#9739) (Bug#9738)
7301 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7303 * doc.c (get_doc_string): Encode file name (bug#9735).
7305 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7307 * bidi.c (bidi_level_of_next_char):
7308 * xdisp.c (get_visually_first_element): Remove old incorrect
7309 comments regarding the Unicode Line Separator character.
7311 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7313 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7315 * alloc.c (Fgc_status): Do not access beyond zombies array
7316 boundary if nzombies > MAX_ZOMBIES.
7317 * alloc.c (dump_zombies): Add missing format specifier.
7319 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7321 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7322 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7324 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7325 Some packages use them to denote characters with modifiers.
7327 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7329 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7330 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7331 matching a pp-number. Rename parameter var to var1.
7333 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7335 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7337 2011-10-08 Glenn Morris <rgm@gnu.org>
7339 * callint.c (Fcall_interactively): Give a more explicit error for the
7340 'c' case with a non-character input. (Bug#8479)
7342 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7344 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7346 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7347 lines that are hscrolled on the left.
7349 * dispnew.c (buffer_posn_from_coords): Account for a possible
7350 presence of header-line. (Bug#4426)
7352 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7354 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7355 Don't advertise functionality which we discourage or doesn't work.
7357 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7359 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7360 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7361 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7362 this makes Emacs dump core during garbage collection on rare
7363 occasions. sizeof is obviously inferior to offsetof here, so
7364 stick with offsetof.
7365 (GC_POINTER_ALIGNMENT): New macro.
7366 (mark_memory): Omit 3rd (offset) arg; caller changed.
7367 Don't assume EMACS_INT alignment is the same as pointer alignment.
7369 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7371 * keyboard.c (read_key_sequence_remapped): New var.
7372 (read_key_sequence): Compute remapping in the right buffer.
7373 (command_loop_1): Use read_key_sequence's remapping directly.
7375 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7377 * dired.c (file_name_completion): Don't expand file name.
7378 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7379 before checking file name handler.
7381 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7382 they've been requested explicitly (bug#9591).
7384 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7386 * keymap.c (Fsingle_key_description): Use make_specified_string
7387 instead of build_string to build string from push_key_description.
7390 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7392 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7393 This fixes a Y2038 bug on 64-bit hosts.
7394 * buffer.c (reset_buffer):
7395 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7396 (Fclear_buffer_auto_save_failure):
7397 Use 0, not -1, to represent an unset failure time, since time_t
7398 might not be signed.
7400 Remove dependency on glibc malloc internals.
7401 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7402 Move back here from lisp.h, but with their new implementations.
7403 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7404 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7405 * charset.c (charset_table_init): New static var.
7406 (syms_of_charset): Use it instead of xmalloc. This removes a
7407 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7408 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7409 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7410 Move back to alloc.c.
7411 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7412 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7414 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7416 * nsterm.m (windowDidResize): Call x_set_window_size only when
7417 ns_in_resize is true. Otherwise set pixelwidth/height and
7418 call change_frame_size (Bug#9628).
7420 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7422 Port --enable-checking=all to Fedora 14 x86-64.
7423 * charset.c (syms_of_charset): Also account for glibc malloc's
7424 internal overhead when calculating the initial malloc maximum.
7426 Port --enable-checking=all to Fedora 14 x86.
7427 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7429 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7430 (overrun_check_realloc, overrun_check_free):
7431 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7432 That way, xmalloc returns a properly-aligned pointer even if
7433 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7434 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7435 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7436 into account when calculating the initial malloc maximum.
7437 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7438 Move here from alloc.c, so that charset.c can use it too.
7439 Properly align; the old code wasn't right for common 32-bit hosts
7440 when configured with --enable-checking=all.
7441 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7442 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7444 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7446 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7449 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7451 * xdisp.c (compute_display_string_end): If there's no display
7452 string at CHARPOS, return -1.
7454 * bidi.c (bidi_fetch_char): When compute_display_string_end
7455 returns a negative value, treat the character as a normal
7456 character not covered by a display string. (Bug#9624)
7458 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7460 * lread.c (Fread_from_string): Fix typo in docstring.
7462 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7464 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7465 newline, reseat the iterator instead of bidi-iterating there one
7466 character at a time. (Bug#9610)
7467 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7468 TO_CHARPOS if the bidi iterator is at base embedding level.
7470 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7472 * lread.c (readevalloop): Use correct code for NBSP.
7473 (read1): Likewise. (Bug#9608)
7475 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7477 * dbusbind.c (Fdbus_register_signal): When service is not
7478 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7480 2011-09-25 Glenn Morris <rgm@gnu.org>
7482 * buffer.c (truncate-lines): Doc fix.
7484 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7486 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7487 (Fset_window_next_buffers): Doc fix.
7489 2011-09-24 Glenn Morris <rgm@gnu.org>
7491 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7493 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7495 Fix minor problems found by static checking.
7496 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7497 * indent.c (Fvertical_motion): Fix == vs = typo.
7499 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7501 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7502 Default value is now t. Doc fix.
7504 * indent.c (Fvertical_motion): Compute and apply the overshoot
7505 logic when moving up, not only when moving down. Fix the
7506 confusing name and values of the it_overshoot_expected variable;
7507 logic changes accordingly. (Bug#9254) (Bug#9549)
7509 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7510 CHARPOS is covered by a display string which includes newlines.
7511 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7512 is covered by a display string with embedded newlines.
7514 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7516 * dbusbind.c (Fdbus_register_signal): Add match rule to
7517 Vdbus_registered_objects_table. (Bug#9581)
7518 (Fdbus_register_method, Vdbus_registered_objects_table):
7521 2011-09-24 Jim Meyering <meyering@redhat.com>
7523 do not ignore write error for any output size
7524 The previous change was incomplete.
7525 While it makes emacs --batch detect the vast majority of stdout
7526 write failures, errors were still ignored whenever the output size is
7527 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7528 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7529 && echo FAIL: ignored write error
7530 FAIL: ignored write error
7531 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7532 && echo FAIL: ignored write error
7533 FAIL: ignored write error
7534 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7536 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

7539 non-successfully if a write error occurred on stdout. (Bug#9574)
7541 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7543 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7546 * dispextern.h (struct it): Update the comment documenting what
7549 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7551 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7552 a display string, extend search for cursor position to end of row.
7553 (find_row_edges): If the row ends in a newline from a display
7554 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7555 Handle the case of a display string with multiple newlines.
7556 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7557 non-empty line. Fixes confusing cursor motion with arrow keys at
7558 the beginning of a line that starts with whitespace.

7567 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7570 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7572 * xdisp.c (display_line): Record maximum and minimum buffer
7573 positions even if no glyphs were produced (e.g., by a zero-width
7574 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7575 buffer positions that will be removed from the glyph row because
7577 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7578 column is beyond frame width: don't subtract 1 "pixel" when
7579 computing width of the stretch.
7580 (reseat_at_next_visible_line_start): Undo the change made on
7581 2011-09-17 that saved paragraph information and restored it after
7582 the call to `reseat'. (Bug#9545)
7584 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7586 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7587 and turn window cursor on if cleared (Bug#9415).

7600 Fix minor problem found by static checking.
7601 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7602 initialized, to pacify gcc -Wuninitialized.
7604 * fileio.c: Report proper errno when syscall falls.
7605 (Finsert_file_contents): Save and restore errno,
7606 so that report_file_error outputs the correct diagnostic.
7607 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7609 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7611 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7613 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7615 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7616 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7618 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7620 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7621 about the current paragraph and restore it after the call to reseat.
7623 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7624 (bidi_find_paragraph_start): Search back for paragraph beginning
7625 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7626 (bidi_move_to_visually_next): Only trigger paragraph-related
7627 computations when the last character is a newline or at EOB, not
7628 just any NEUTRAL_B. (Bug#9470)
7630 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7631 truncated lines if point is covered by a display string. (Bug#9524)
7633 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7635 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7636 (cons_to_x_long): New function.
7637 (lisp_data_to_selection_data): Use it. Correct the test for
7638 short-versus-long data; it was negated. Break out of vector
7639 loop, for efficiency, when a long datum is discovered.
7641 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7643 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7645 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7647 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7648 GCC PR/17406) by declaring this function with external scope.

7671 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7672 This occurs when processing a multibyte format.
7673 Problem reported by Wolfgang Jenker.
7675 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7677 * xdisp.c (try_cursor_movement): Only check for exact match if
7678 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7680 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7682 Remove unused external symbols.
7683 * dispextern.h (calc_pixel_width_or_height): Remove decl.

7687 * w32term.c: Fix comment to match code.
7688 * xterm.c, xterm.h (x_catching_errors): Remove.
7690 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7692 * xselect.c: Use signed conversions more consistently (Bug#9498).
7693 (selection_data_to_lisp_data): Assume incoming selection data are
7694 signed integers, not unsigned. This is to be consistent with
7695 outgoing selection data, which was modified to use signed integers
7696 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7697 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7698 expects long, not unsigned long.

7702 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7703 computation of loop end. Reported by Johan Bockgård

7713 rather than the other way around. (Bug#2496)
7715 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7717 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7719 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7721 * minibuf.c (Fread_from_minibuffer): Doc fix.
7723 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7725 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7726 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7728 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7730 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7731 value for non-existent files.
7733 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7735 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7736 set its "size" to -1. This will set the modtime_size field of
7737 the corresponding buffer to -1, which is what
7738 verify-visited-file-modtime expects for files that do not exist.
7741 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7743 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7745 * lisp.h: ... from here. push_key_description is no longer
7746 defined in keyboard.c, so its declaration should not be in
7747 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7748 logically belongs with push_key_description.
7750 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7752 * buffer.h: Include <sys/types.h> instead of <time.h>.
7753 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7754 Problem reported by Herbert J. Skuhra.
7756 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7758 * xml.c (parse_region): Make the parsing work for
7759 non-comment-starting XML files again (bug#9144).
7761 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7763 * image.c (gif_load): Fix calculation of bottom and right corner.
7766 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7768 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7769 redisplay in small windows.
7771 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7773 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7775 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7777 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7778 Operate on live windows only.
7780 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7782 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7784 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7786 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7787 only under bidi iteration.
7789 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7791 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7793 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7795 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7796 Without this fix, the command to link temacs failed due to an
7797 undefined symbol __builtin_isnan. This is because
7798 /usr/include/iso/math_c99.h #defines isnan(x) to
7799 __builtin_isnan(x), but the bundled gcc, which identifies itself
7800 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7802 * floatfns.c (isnan): #undef, and then #define to a clone of
7804 (Fisnan): Always define, since it's always available now.
7805 (syms_of_floatfns): Always define isnan at the Lisp level.
7807 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7809 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7811 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7813 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7814 The previous code assumed that file offsets (off_t values) fit in
7815 EMACS_INT variables, which is not true on typical 32-bit hosts.
7816 The code messed up by falsely reporting buffer overflow in cases
7817 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7818 when "big" contains more than 2**29 bytes, even though this
7819 inserts just one byte and does not overflow the buffer.
7820 (Finsert_file_contents): Store file offsets as off_t
7821 values, not as EMACS_INT values. Check for overflow when
7822 converting between EMACS_INT and off_t. When checking for
7823 buffer overflow or for overlap, take the offsets into account.
7824 Don't use EMACS_INT for small values where int suffices.
7825 When checking for overlap, fix a typo: ZV was used where
7826 ZV_BYTE was intended.
7827 (Fwrite_region): Don't assume off_t fits into 'long'.
7828 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7830 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7832 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7834 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7836 sprintf-related integer and memory overflow issues (Bug#9412).
7838 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7839 (esprintf, exprintf, evxprintf): New functions.
7840 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7841 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7842 (modify_event_symbol): Do not assume that the length of
7843 name_alist_or_stem is safe to alloca and fits in int.
7844 (Fexecute_extended_command): Likewise for function name and binding.
7845 (Frecursion_depth): Wrap around reliably on integer overflow.
7846 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7847 since some callers pass EMACS_INT values.
7848 (Fsingle_key_description): Don't crash if symbol name contains more
7849 than MAX_ALLOCA bytes.
7850 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7851 (get_minibuffer): Arg is now EMACS_INT, not int.
7852 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7853 (esprintf, exprintf, evxprintf): New decls.
7854 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7856 * dbusbind.c (signature_cat): New function.
7857 (xd_signature, Fdbus_register_signal):
7858 Do not overrun buffer; instead, report string overflow.
7860 * dispnew.c (add_window_display_history): Don't overrun buffer.
7861 Truncate instead; this is OK since it's just a log.
7863 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7864 even if the time zone offset is outlandishly large.
7865 Don't mishandle offset == INT_MIN.
7867 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7868 when creating daemon; the previous buffer-overflow check was incorrect.
7870 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7871 which has the guts of the old verror function.
7873 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7874 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7876 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7877 (font_unparse_xlfd): Don't blindly alloca long strings.
7878 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7879 fits in int, when using sprintf. Use single snprintf to count
7880 length of string rather than counting it via multiple sprintfs;
7881 that's simpler and more reliable.
7882 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7883 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7884 sprintf, in case result does not fit in int.
7886 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7887 (fontset_from_font): Print it.
7889 * frame.c (tty_frame_count): Now printmax_t, not int.
7890 (make_terminal_frame, set_term_frame_name): Print it.
7891 (x_report_frame_params): In X, window IDs are unsigned long,
7892 not signed long, so print them as unsigned.
7893 (validate_x_resource_name): Check for implausibly long names,
7894 and don't assume name length fits in 'int'.
7895 (x_get_resource_string): Don't blindly alloca invocation name;
7896 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7899 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7900 (xg_check_special_colors, xg_set_geometry):
7901 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7903 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7904 Use esprintf, not sprintf, in case result does not fit in int.
7906 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7907 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7908 it as a large positive number.
7909 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7910 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7912 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7913 in case result does not fit in int.
7915 * print.c (float_to_string): Detect width overflow more reliably.
7916 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7917 buffer overrun. Don't assume list length fits in 'int'. Treat
7918 print length of 0 as 0, not as infinity; to be consistent with other
7919 uses of print length in this function. Don't overflow print length
7920 index. Don't assume hash table size fits in 'long', or that
7921 vectorlike size fits in 'unsigned long'.
7923 * process.c (make_process): Use printmax_t, not int, to format
7924 process-name gensyms.
7926 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7928 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7929 to avoid potential buffer overrun.
7931 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7932 if X resource line is longer than 512 bytes.
7934 * xfns.c (x_window): Make sprintf buffer a bit bigger
7935 to avoid potential buffer overrun.
7937 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7939 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7941 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7943 Integer overflow fixes for scrolling, etc.
7944 Without these, Emacs silently mishandles large integers sometimes.
7945 For example, "C-u 4294967297 M-x recenter" was treated as if
7946 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7948 * xdisp.c (try_window_id): Check Emacs fixnum range before
7949 converting to 'int'.
7951 * window.c (window_scroll_line_based, Frecenter):
7952 Check that an Emacs fixnum is in range before assigning it to 'int'.
7953 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7954 values converted from Emacs fixnums.
7955 (Frecenter): Don't wrap around a line count if it is out of 'int'
7956 range; instead, treat it as an extreme value.
7957 (Fset_window_configuration, compare_window_configurations):
7958 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7960 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7961 that can exceed INT_MAX. Check that EMACS_INT value is in range
7962 before assigning it to the (possibly-narrower) index.
7963 (match_limit): Don't assume that a fixnum can fit in 'int'.
7965 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7968 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7969 (Fvertical_motion): Don't wrap around LINES values that don't fit
7970 in 'int'. Instead, treat them as extreme values. This is good
7971 enough for windows, which can't have more than INT_MAX lines anyway.
7973 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7975 * Require libxml/parser.h to avoid compilation warning.
7977 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7979 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7980 since this reportedly can destroy thread storage.
7982 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7984 * syntax.c (find_defun_start): Update all cache variables if
7985 exiting early (Bug#9401).
7987 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7989 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7991 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7992 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7993 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7995 * term.c (tty_append_glyph): New function.
7996 (produce_stretch_glyph): Static function and its prototype deleted.
7998 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8001 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8003 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8004 when checking :margin (Bug#9390).
8005 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8006 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8007 so that the name doesn't mislead. All uses changed.
8009 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8011 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8014 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8016 * xdisp.c (move_it_to): Don't bail out early when reaching
8017 position beyond to_charpos, if we are scanning backwards.
8018 (move_it_vertically_backward): When DY == 0, make sure we get to
8019 the first character in the line after the newline.
8021 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8023 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8024 (ccl_driver): Do not generate an out-of-range pointer.
8025 (Fccl_execute_on_string): Remove unnecessary check for
8026 integer overflow, noted by Stefan Monnier in
8027 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8028 Remove a FIXME that didn't need fixing.
8029 Simplify the newly-introduced buffer reallocation code.
8031 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8033 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8035 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8037 Integer and memory overflow issues (Bug#9196).
8039 * doc.c (get_doc_string): Rework so that
8040 get_doc_string_buffer_size is the actual buffer size, rather than
8041 being 1 less than the actual buffer size; this makes xpalloc more
8044 * image.c (x_allocate_bitmap_record, cache_image):
8045 * xselect.c (Fx_register_dnd_atom):
8046 Simplify previous changes by using xpalloc.
8048 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8049 since either will do and ptrdiff_t is convenient with xpalloc.
8051 * charset.c (charset_table_size)
8052 (struct charset_sort_data.priority): Now ptrdiff_t.
8053 (charset_compare): Don't overflow if priorities differ greatly.
8054 (Fsort_charsets): Don't assume list length fits in int.
8055 Check for size-calculation overflow when allocating sort data.
8056 (syms_of_charset): Allocate an initial charset table that is
8057 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8059 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8061 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8062 The actual value is always <= INT_MAX, and leaving it unsigned made
8063 overflow checking harder.
8065 * dispextern.h (struct glyph_matrix.rows_allocated)
8066 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8067 with xpalloc. The values are still always <= INT_MAX.
8069 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8071 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8072 (SAFE_NALLOCA): New macro.
8074 * region-cache.c (struct boundary.pos, find_cache_boundary)
8075 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8076 (set_cache_region, invalidate_region_cache)
8077 (revalidate_region_cache, know_region_cache, region_cache_forward)
8078 (region_cache_backward, pp_cache):
8079 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8080 so that ptrdiff_t * can be passed to xpalloc.
8081 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8082 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8083 (pp_cache): Don't assume cache_len fits in int.
8084 * region-cache.h: Adjust extern decls to match.
8086 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8087 EMACS_INT, since either will do, for xpalloc.
8089 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8090 (xnmalloc, xnrealloc, xpalloc): New functions.
8092 * bidi.c (bidi_shelve_header_size): New constant.
8093 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8094 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8096 * bidi.c (bidi_cache_shrink):
8097 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8099 Don't update size of array until after memory allocation succeeds,
8100 because xmalloc/xrealloc may not return.
8101 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8102 now that we have proper integer overflow checking.
8103 (record_overlay_string, overlay_strings): Catch overflows when
8104 calculating size of overlay_str_buf.
8106 * callproc.c (Fcall_process): Check for size overflow when
8107 calculating size of args2.
8108 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8109 Normally we prefer signed values, but sticking with ptrdiff_t would
8110 require adding more-complicated checks.
8112 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8113 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8114 Redo buffer-overflow calculations to avoid integer overflow.
8115 Add a FIXME comment where memory seems to be over-allocated.
8117 * character.c (Fstring): Check for size-calculation overflow.
8119 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8120 unnecessary integer overflow. Check for size overflow.
8121 (encode_coding_object): Don't update size until xmalloc succeeds.
8123 * composite.c (get_composition_id): Check for overflow in glyph
8124 length calculations.
8126 Integer and memory overflow fixes for display code.
8127 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8128 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8129 (scrolling_window): Check for overflow in size calculations.
8130 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8131 Don't assume glyph table len fits in int.
8132 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8133 (row_table_size): Now ptrdiff_t, not int.
8134 (scrolling_window): Avoid overflow in size calculations.
8135 Don't update size until allocation succeeds.
8136 * fns.c (concat): Check for overflow in size calculations.
8137 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8138 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8139 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8141 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8142 (get_doc_string): Check for size calculation overflow.
8143 Don't update size until allocation succeeds.
8144 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8145 EMACS_INT, where ptrdiff_t will do.
8146 (Fsubstitute_command_keys): Check for string overflow.
8148 * editfns.c (set_time_zone_rule): Don't assume environment length
8150 (message_length): Now ptrdiff_t, not int.
8151 (Fmessage_box): Don't update size until allocation succeeds.
8152 Don't assume message length fits in int.
8153 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8155 * emacs.c (main): Do not reallocate argv, since there is a null at
8156 the end that can be overwritten, and this way there's no need to
8157 worry about size-calculation overflow.
8158 (sort_args): Check for size-calculation overflow.
8160 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8162 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8164 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8165 (x_set_scroll_bar_width, x_figure_window_size):
8166 Check for integer overflow.
8167 (x_set_alpha): Do not assume XINT fits in int.
8169 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8170 This is for the members text_lines, text_cols, total_lines, total_cols,
8171 where the system imposes an 'int' limit.
8173 * fringe.c (Fdefine_fringe_bitmap):
8174 Don't update size until alloc works.
8176 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8177 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8179 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8180 Check for size-calculation overflow.
8181 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8182 do, as we prefer signed integers.
8183 (id_to_widget.max_size, id_to_widget.used)

8236 (Fset_match_data): Don't assume list lengths fit in 'int'.
8238 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,

8286 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8287 (X_LONG_MIN): New macros.
8288 Use them to make the following changes clearer.
8289 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8290 This change doesn't affect the value now, but it may help remind
8291 future maintainers not to raise the value too much later.
8292 (SELECTION_QUANTUM): Remove, replacing with ...
8293 (selection_quantum): ... new function, which avoids overflow.
8295 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

8315 Don't double-block input; malloc is safe here. Don't assume 2**34
8316 - 4 fits in unsigned long. Add an xassert to check
8317 XGetWindowProperty overflow. Be more careful about overflow
8318 calculations, and distinguish size from memory overflow better.

8324 in the range -65535 through -1 fit in an X unsigned short.
8325 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8326 result parameters unless successful. Rely on cons_to_unsigned
8327 to report problems with elements; the old code wasn't right anyway.
8328 (x_check_property_data): Check for int overflow; we cannot use
8329 a wider type due to X limits.

8362 * lisp.h (hash_lookup, hash_put):
8363 * minibuf.c (Ftest_completion):
8364 Use ptrdiff_t for hash table indexes, not int (which is too
8365 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

8399 (x_send_scroll_bar_event): Likewise. Check that the size does not
8400 exceed limits imposed by XClientMessageEvent, as well as the usual
8401 ptrdiff_t and size_t limits.
8403 * keyboard.c: Overflow, signedness and related fixes.
8404 (make_lispy_movement): Use same integer type in forward decl
8405 that is used in the definition.
8406 (read_key_sequence, keyremap_step):
8407 Change bufsize argument back to int, undoing my 2011-03-30 change.
8408 We prefer signed types, and int is wide enough here.
8409 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8410 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8411 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8412 length, not size_t. Use ptrdiff_t for index, not int.

8442 Prefer int to unsigned where either will do.
8443 (tiff_handler): New function, combining the cores of the
8444 old tiff_error_handler and tiff_warning_handler.
8445 This function is rewritten to use vsnprintf and thereby avoid
8446 stack buffer overflows. It uses only the features of vsnprintf
8447 that are common to both POSIX and native Microsoft.
8448 (tiff_error_handler, tiff_warning_handler): Use it.
8449 (tiff_load, gif_load, imagemagick_load_image):

8453 the integer types that MagickCropImage accepts. Don't assume
8454 Vimagemagick_render_type has a nonnegative value. Don't assume
8455 size_t fits in 'long'.
8456 (gs_load): Use printmax_t to print the widest integers possible.

8475 Don't advance `row' beyond the last row of the window.
8477 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8478 into disp_prop; all users changed.

8496 positioning on the newline at EOL of R2L text within L2R
8497 paragraph, and vice versa.
8498 (try_cursor_movement): Check continued rows, in addition to
8499 continuation rows. Fixes unwarranted scroll when point enters a
8500 continued line of R2L text within an L2R paragraph, or vice versa.
8501 (cursor_row_p): Consider the case of point being equal to
8502 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

8531 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8532 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8533 candidate is selected by the mouse, and that candidate has a
8534 composed character under the mouse.
8536 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8537 coordinates reported by pos-visible-in-window-p for a composed

8552 * image.c (gif_load): Don't assume that each subimage has the same
8553 dimensions as the base image. Handle disposal method that is
8554 "undefined" by the gif spec (Bug#9335).
8556 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8558 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8563 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8564 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8565 from an Org mode buffer to a Speedbar frame.
8567 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8568 a composition, take its buffer position from IT->cmp_it.charpos.
8569 Fixes cursor positioning at the beginning of a line that begins
8570 with a composed character.
8572 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8574 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8575 character bidirectional type, use STRONG_L instead. Fixes crashes
8576 in a buffer produced by `describe-categories'.
8578 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8579 members before the level stack, so they would be saved and
8580 restored when copying iterator state. Fixes incorrect reordering
8581 around TABs covered by display properties.
8583 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8648 2011-08-14 Kenichi Handa <handa@m17n.org>
8650 * process.c (create_process): Call setup_process_coding_systems
8651 after the pid of the process is set to -1 (Bug#8162).
8653 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8655 * xdisp.c (move_it_in_display_line_to): Don't invoke
8656 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8657 ppos_it. Fixes vertical cursor motion when line beginning is
8658 covered by an image. (Bug#9296)
8660 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8662 * nsterm.h (ns_run_ascript): Declare.
8663 (NSAPP_DATA2_RUNASSCRIPT): Define.
8665 * nsfns.m (as_script, as_result, as_status): New static variables.
8666 (ns_run_ascript): New function.
8667 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8668 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8669 the event loop. Get status from as_status (Bug#7276).
8671 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8672 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8673 the event loop (Bug#7276).
8675 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8677 * gnutls.c (QCgnutls_bootprop_priority)
8678 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8679 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8680 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8681 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8682 (QCgnutls_bootprop_verify_hostname_error)
8683 (QCgnutls_bootprop_callbacks_verify): Rename from
8684 Qgnutls_bootprop_..., all uses changed.
8686 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8689 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8691 * xfaces.c (Qframe_set_background_mode): Now static.
8692 * dispextern.h (Qframe_set_background_mode): Remove decl.
8694 * process.c (Fnetwork_interface_info): Declare local only if needed.
8696 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8698 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8699 (Fnetwork_interface_list): Allocate in increments of bytes instead
8700 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8701 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8703 (struct ifflag_def): notrailers is smart on OSX.
8704 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8705 Get hardware address with getifaddrs if available.
8707 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8709 * xdisp.c (iterate_out_of_display_property): xassert that
8710 IT->position is set to within IT->object's boundaries. Break from
8711 the loop as soon as EOB is reached; avoids infloops in redisplay
8712 when IT->position is set up wrongly due to some bug.
8713 Set IT->current to match the bidi iterator unconditionally.
8714 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8715 entry. Force push_it to save on the stack the current
8716 buffer/string position, to be restored by pop_it. Fix flags in
8717 the iterator structure wrt the object coming from a display
8718 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8719 properties. (Bug#9284)
8721 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8723 * fontset.c (fontset_get_font_group): Add proper type checks.
8726 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8728 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
8729 and LC_VERSION_MIN_MACOSX.
8730 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8731 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8733 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8735 * xdisp.c (forward_to_next_line_start): Allow to use the
8736 no-display-properties-and-no-overlays under bidi display.
8737 Set disp_pos in the bidi iterator to avoid searches for display
8738 properties and overlays.
8740 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8742 * editfns.c (Fset_time_zone_rule): Document relationship with the
8745 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8746 the font entity extracted from the cache (Bug#8109).
8748 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8750 * composite.c (autocmp_chars): Don't reset point. That is done by
8751 restore_point_unwind (Bug#5984).
8753 2011-08-07 Juri Linkov <juri@jurta.org>
8755 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8756 to show the arg `TIME' instead of `TIMEVAL'.
8758 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8760 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8761 display property strides EOL and includes a newline, as in
8762 longlines-mode. (Bug#9254)
8763 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8764 word-wrap under bidirectional display. (Bug#9224)
8766 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8767 is non-zero, even if the data buffer is NULL. Fixes a crash in
8768 vertical-motion with longlines-mode. (Bug#9254)
8770 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8772 * bidi.c <bidi_cache_total_alloc>: Now static.
8773 (bidi_initialize): Initialize bidi_cache_total_alloc.
8775 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8778 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8779 amount allocated this far in `bidi_cache_total_alloc'.
8780 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8781 non-zero, only free the data buffer without restoring the cache
8782 contents. All callers changed.
8784 * dispextern.h (bidi_unshelve_cache): Update prototype.
8786 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8787 (move_it_in_display_line, move_it_to)
8788 (move_it_vertically_backward, move_it_by_lines): Replace the call
8789 to xfree to an equivalent call to bidi_unshelve_cache.
8790 (move_it_in_display_line_to): Fix logic of returning
8791 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8793 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8795 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8796 came from a string character with a `cursor' property. (Bug#9229)
8798 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8800 * Makefile.in (LIB_PTHREAD): New variable.
8801 (LIBES): Add LIB_PTHREAD (Bug#9216).
8803 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8804 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8806 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8808 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8810 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8812 * xterm.c (x_find_topmost_parent): New function.
8813 (x_set_frame_alpha): Find topmost parent window with
8814 x_find_topmost_parent and set the property there also (bug#9181).
8815 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8817 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8819 * callproc.c (Fcall_process): Avoid vfork clobbering
8820 the local vars buffer, coding_systems, current_dir.
8822 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8824 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8826 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8828 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8829 so that it is not optimized away.
8831 * xdisp.c (compute_display_string_pos): Remove unused local.
8833 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8835 Fix slow cursor motion and scrolling in large buffers with
8836 selective display, like Org Mode buffers. (Bug#9218)
8838 * dispextern.h (struct bidi_it): New member disp_prop_p.
8840 * xdisp.c: Remove one-slot cache of display string positions.
8841 (compute_display_string_pos): Accept an additional argument
8842 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8843 for a display string or property. If found, set DISP_PROP_P
8846 * bidi.c (bidi_fetch_char): Accept an additional argument
8847 DISP_PROP_P, and pass it to compute_display_string_pos.
8848 Only handle text covered by a display string if DISP_PROP_P is returned
8849 non-zero. All callers of bidi_fetch_char changed.
8851 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8853 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8855 2010-12-03 Don March <don@ohspite.net>
8857 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8858 last character M-[char] is translated to ESC [char] (bug#7541).
8860 2011-08-02 Kenichi Handa <handa@m17n.org>
8862 * lisp.h (uniprop_table): Extern it.
8864 * chartab.c (uniprop_table): Make it non-static.
8866 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8868 * xdisp.c (forward_to_next_line_start): Accept additional argument
8869 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8871 (reseat_at_next_visible_line_start): Use the bidi iterator state
8872 returned by forward_to_next_line_start to restore the state of
8873 it->bidi_it after backing up to previous newline. (Bug#9212)
8875 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8877 * regex.c (re_comp): Protoize.
8878 (re_exec): Fix return type.
8879 (regexec): Fix type of `ret'. (Bug#9203)
8881 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8883 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8884 This is needed if max-image-size is a floating-point number.
8886 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8888 * print.c (print_object): Print empty symbol as ##.
8890 * lread.c (read1): Read ## as empty symbol.
8892 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8894 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8895 setting frame foreground color (Bug#9175).
8896 (x_set_background_color): Likewise.
8898 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8899 contents (Bug#9176).
8900 (EmacsTooltip -init): Remove bezels and add shadows to
8903 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8904 or scroll bar (Bug#8470).
8906 * nsfont.m (nsfont_open): Remove assignment to voffset and
8907 unnecessary vars hshink, expand, hd, full_height, min_height.
8908 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8910 * nsterm.h (nsfont_info): Remove voffset field.
8912 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8914 Implement strike-through and overline on NextStep (Bug#8863).
8916 * nsfont.m (nsfont_open): Use underline position provided by font,
8917 instead of hard-coded value of 2.
8918 (nsfont_draw): Call ns_draw_text_decoration instead.
8920 * nsterm.h: Add declaration for ns_draw_text_decoration.
8922 * nsterm.m (ns_draw_text_decoration): New function for drawing
8923 underline, overline, and strike-through.
8924 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8925 ns_draw_text_decoration. Change treatment of cursor drawing to
8926 accommodate underlining, etc.
8928 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8930 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8933 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8935 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8936 Without this fix, if a signal arrives just after memory fills up,
8937 'malloc' might be invoked reentrantly.
8939 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8940 In other words, assume that every image size is allowed, on non-X
8941 hosts. This assumption is probably wrong, but it lets Emacs compile.
8943 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8945 * regex.c (re_iswctype): Convert return values to boolean.
8947 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8949 * xdisp.c (compute_display_string_pos): Don't use cached display
8950 string position if the buffer had its restriction changed.
8953 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8955 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8957 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8959 Integer signedness and overflow and related fixes. (Bug#9079)
8961 * bidi.c: Integer size and overflow fixes.
8962 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8963 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8964 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8965 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8966 (bidi_find_other_level_edge):
8967 Use ptrdiff_t instead of EMACS_INT where either will do.
8968 This works better on 32-bit hosts configured --with-wide-int.
8969 (bidi_cache_ensure_space): Check for size-calculation overflow.
8970 Use % rather than repeated addition, for better worst-case speed.
8971 Don't set bidi_cache_size until after xrealloc returns, because it
8973 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8974 (bidi_cache_ensure_space): Also check that the bidi cache size
8975 does not exceed that of the largest Lisp string or buffer. See Eli
8976 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8978 * alloc.c (__malloc_size_t): Remove.
8979 All uses replaced by size_t. See Andreas Schwab's note
8980 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8982 * image.c: Improve checking for integer overflow.
8983 (check_image_size): Assume that f is nonnull, since
8984 it is always nonnull in practice. This is one less thing to
8985 worry about when checking for integer overflow later.
8986 (x_check_image_size): New function, which checks for integer
8987 overflow issues inside X.
8988 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8989 This removes the need for a memory_full check.
8990 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8991 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8992 (xbm_read_bitmap_data): Change locals back to 'int', since
8993 their values must fit in 'int'.
8994 (xpm_load_image, png_load, tiff_load):
8995 Invoke x_create_x_image_and_pixmap earlier,
8996 to avoid much needless work if the image is too large.
8997 (tiff_load): Treat overly large images as if
8998 x_create_x_image_and_pixmap failed, not as malloc failures.
8999 (gs_load): Use x_check_image_size.
9001 * gtkutil.c: Omit integer casts.
9002 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9003 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9005 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9007 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9008 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9009 would wrongly return t on a 64-bit host.
9011 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9012 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9013 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9014 and therefore cause GCC to emit a bogus diagnostic in some cases.
9016 * image.c: Integer signedness and overflow and related fixes.
9017 This is not an exhaustive set of fixes, but it's time to
9018 record what I've got.
9019 (lookup_pixel_color, check_image_size): Remove redundant decls.
9020 (check_image_size): Don't assume that arbitrary EMACS_INT values
9021 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9022 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9023 (tiff_load, imagemagick_load_image):
9024 Check for overflow in size calculations.
9025 (x_create_x_image_and_pixmap): Remove unnecessary test for
9026 xmalloc returning NULL; that can't happen.
9027 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9028 (xpm_color_bucket): Use better integer hashing function.
9029 (xpm_cache_color): Don't possibly over-allocate memory.
9030 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9031 (gif_memory_source):
9032 Use ptrdiff_t, not int or size_t, to record sizes.
9033 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9034 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9035 either works, as we prefer signed integers.
9036 (tiff_read_from_memory, tiff_write_from_memory):
9037 Return tsize_t, not size_t, since that's what the TIFF API wants.
9038 (tiff_read_from_memory): Don't fail simply because the read would
9039 go past EOF; instead, return a short read.
9040 (tiff_load): Omit no-longer-needed casts.
9041 (Fimagemagick_types): Don't assume size fits into 'int'.
9043 Improve hashing quality when configured --with-wide-int.
9044 * fns.c (hash_string): New function, taken from sxhash_string.
9045 Do not discard information about ASCII character case; this
9046 discarding is no longer needed.
9047 (sxhash-string): Use it. Change sig to match it. Caller changed.
9048 * lisp.h: Declare it.
9049 * lread.c (hash_string): Remove, since we now use fns.c's version.
9050 The fns.c version returns a wider integer if --with-wide-int is
9051 specified, so this should help the quality of the hashing a bit.
9053 * emacs.c: Integer overflow minor fix.
9054 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9055 Define only if GNU_LINUX.
9056 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9058 * dispnew.c: Integer signedness and overflow fixes.
9059 Remove unnecessary forward decls, that were a maintenance hassle.
9060 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9062 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9063 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9064 (prepare_desired_row, line_draw_cost):
9065 Use int, not unsigned, where either works.
9066 (save_current_matrix, restore_current_matrix):
9067 Use ptrdiff_t, not size_t, where either works.
9068 (init_display): Check for overflow more accurately, and without
9069 relying on undefined behavior.
9071 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9072 Remove, replacing with the new symbols in lisp.h. All uses changed.
9073 * fileio.c (make_temp_name):
9074 * filelock.c (lock_file_1, lock_file):
9075 * xdisp.c (message_dolog):
9076 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9077 Use pMd etc. instead.
9078 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9079 replacing the pWIDE etc. symbols removed from editfns.c.
9081 * keyboard.h (num_input_events): Now uintmax_t.
9082 This is (very slightly) less likely to mess up due to wraparound.
9085 * buffer.c: Integer signedness fixes.
9086 (alloc_buffer_text, enlarge_buffer_text):
9087 Use ptrdiff_t rather than size_t when either will do, as we prefer
9090 * alloc.c: Integer signedness and overflow fixes.
9091 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9092 (__malloc_size_t): Default to size_t, not to int.
9093 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9094 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9095 Prefer ptrdiff_t to size_t when either would do, as we prefer
9097 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9098 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9099 Now const. Initialize with values that are in range even if char
9101 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9102 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9103 These functions do the right thing with sizes > 2**32.
9104 (check_depth): Now ptrdiff_t, not int.
9105 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9106 Adjust to new way of storing sizes. Check for size overflow bugs
9108 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9109 slightly wrong anyway, as it missed one instance of
9110 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9111 (refill_memory_reserve): Omit needless cast to size_t.
9112 (mark_object_loop_halt): Mark as externally visible.
9114 * xselect.c: Integer signedness and overflow fixes.
9115 (Fx_register_dnd_atom, x_handle_dnd_message):
9116 Use ptrdiff_t, not size_t, since we prefer signed.
9117 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9118 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9119 x_dnd_atoms_size and x_dnd_atoms_length.
9121 * doprnt.c: Prefer signed to unsigned when either works.
9123 * doprnt.c (doprnt):
9125 * xdisp.c (vmessage):
9126 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9127 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9128 prefer signed arithmetic to avoid comparison confusion.
9129 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9130 but is a bit tricky.
9132 Assume freestanding C89 headers, string.h, stdlib.h.
9133 * data.c, doprnt.c, floatfns.c, print.c:
9134 Include float.h unconditionally.
9135 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9136 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9137 * regex.c: Likewise for stddef.h, string.h.
9138 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9139 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9140 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9141 (STDC_HEADERS): Remove obsolete defines.
9142 * sysdep.c: Include limits.h unconditionally.
9144 Assume support for memcmp, memcpy, memmove, memset.
9145 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9146 * regex.c (memcmp, memcpy):
9147 Remove; we assume C89 now.
9149 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9150 (__malloc_safe_bcopy): Remove; no longer needed.
9152 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9153 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9154 well either way, and we prefer signed to unsigned.
9156 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9158 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9159 closes the connection while we're reading (bug#9182).
9161 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9163 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9164 are specified (Bug#9168).
9166 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9168 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9169 Found by GCC static checking and --with-wide-int on a 32-bit host.
9171 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9173 * xdisp.c (compute_display_string_pos): Fix logic of caching
9174 previous display string position. Initialize cached_prev_pos to
9175 -1. Fixes slow-down at the beginning of a buffer.
9177 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9179 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9180 for attrs[LFACE_FONTSET_INDEX].
9182 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9184 * xml.c (parse_region): Remove unused local
9185 that was recently introduced.
9187 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9189 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9190 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9192 * xdisp.c (move_it_in_display_line_to): Record the best matching
9193 position for TO_CHARPOS while scanning the line, and restore it on
9194 exit if none of the characters scanned was an exact match.
9195 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9196 when exact match is impossible due to invisible text, and the
9197 lines are truncated.
9199 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9201 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9204 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9206 Fix a significant slow-down of cursor motion with C-n, C-p,
9207 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9208 auto-repeat under bidi redisplay in fontified buffers.
9209 * xdisp.c (compute_stop_pos_backwards): New function.
9210 (next_element_from_buffer): Call compute_stop_pos_backwards to
9211 find a suitable prev_stop when we find ourselves before
9213 (reseat): Don't look for prev_stop, as that could mean a very long
9215 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9216 <cached_disp_overlay_modiff>: Cache for last found display string
9218 (compute_display_string_pos): Return the cached position if asked
9219 about the same buffer in the same area of character positions, and
9220 the buffer wasn't changed since the time the display string
9221 position was cached.
9223 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9225 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9226 is an integer, which is important for empty lines. (Bug#9149)
9228 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9230 * frame.c (Fmodify_frame_parameters): In tty case, update the
9231 default face if necessary (Bug#4238).
9233 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9235 * editfns.c (Fstring_to_char): No need to explain what a character
9236 is in the docstring (Bug#6576).
9238 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9240 * xml.c (parse_region): Make sure we always return a tree.
9242 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9244 * xml.c (parse_region): If a document contains only comments,
9247 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9249 * xml.c (make_dom): Return comments, too.
9251 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9254 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9255 and the surrounding thread.
9256 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9257 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9258 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9260 * s/openbsd.h (BROKEN_SIGIO): Define.
9261 * unexelf.c (unexec) [__OpenBSD__]:
9262 Don't update the .mdebug section of the Alpha COFF symbol table.
9264 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9266 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9269 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9271 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9272 This fixes some race conditions on the permissions of any newly
9275 * alloc.c (valid_pointer_p): Use pipe, not open.
9276 This fixes some permissions issues when debugging.
9278 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9279 If fchown fails to set both uid and gid, try to set just gid,
9280 as that is sometimes allowed. Adjust the file's mode to eliminate
9281 setuid or setgid bits that are inappropriate if fchown fails.
9283 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9285 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9286 to compare Lisp_Objects.
9287 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9288 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9289 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9291 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9293 * lread.c (read_integer): Unread even EOF character.
9294 (read1): Likewise. Properly record start position of symbol.
9296 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9297 symbol character follows.
9299 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9301 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9302 This works around a problem with the previous change to Fcopy_file.
9303 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9304 and without this change, GCC might complain about discarding
9305 fchown's return value.
9307 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9309 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9311 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9313 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9315 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9317 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9318 it's used from the C level.
9320 * process.c: Use the same condition for POLL_FOR_INPUT in both
9321 keyboard.c and process.c (bug#1858).
9323 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9325 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9326 (Fgnutls_boot): Use it.
9328 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9330 * doc.c (Fsubstitute_command_keys): Revert last change.
9332 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9334 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9335 quotes the next character, and doesn't affect other longer
9336 sequences (bug#8935).
9338 * lread.c (syms_of_lread): Clarify that is isn't only
9339 `eval-buffer' and `eval-defun' that's affected by
9340 `lexical-binding' (bug#8460).
9342 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9344 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9345 bidi redisplay when a line includes both an image and is truncated.
9347 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9349 Fix minor problems found by static checking.
9350 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9351 (elsz): Now a signed constant, not a size_t var. We prefer signed
9352 types to unsigned, to avoid integer comparison confusion. Without
9353 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9354 "cannot optimize loop, the loop counter may overflow", a symptom
9356 * indent.c (Fvertical_motion): Mark locals as initialized.
9357 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9359 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9361 * search.c (Fre_search_backward): Mention `case-fold-search' in
9362 all the re_search_* functions (bug#8138).
9364 * keyboard.c (Fopen_dribble_file): Document when the file is

9374 (compute_display_string_end): Accept additional argument STRING.
9375 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9376 (reseat_to_string): Initialize bidi_it->string.s and
9377 bidi_it->string.schars.
9378 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9379 NULL (avoids a crash in bidi_paragraph_init).
9380 Initialize itb.string.lstring.
9381 (init_iterator): Call bidi_init_it only of a valid
9382 buffer position was specified. Initialize paragraph_embedding to
9384 (reseat_to_string): Initialize the bidi iterator.
9385 (display_string): If we need to ignore text properties of
9386 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9387 original value of -1 will not work with bidi.)
9388 (compute_display_string_pos): First arg is now struct
9389 `text_pos *'; all callers changed. Support display properties on
9391 (compute_display_string_end): Support display properties on Lisp
9393 (init_iterator, reseat_1, reseat_to_string): Initialize the
9394 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9395 when iterating on a string not from display properties).
9396 (compute_display_string_pos, compute_display_string_end):
9397 Fix calculation of the object to scan. Fixes an error when using
9399 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9400 base_level_stop; instead, set base_level_stop to BEGV.
9401 Fixes crashes in vertical-motion.
9402 (next_element_from_buffer): Improve commentary for when
9403 the iterator is before prev_stop.
9404 (init_iterator): Initialize bidi_p from the default value of
9405 bidi-display-reordering, not from buffer-local value. Use the
9406 buffer-local value only if initializing for buffer iteration.
9407 (handle_invisible_prop): Support invisible properties on strings
9408 that are being bidi-reordered.
9409 (set_iterator_to_next): Support bidi reordering of C strings and
9411 (next_element_from_string): Support bidi reordering of Lisp
9413 (handle_stop_backwards): Support Lisp strings as well.
9414 (display_string): Support display of R2L glyph rows.
9415 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9416 (init_iterator): Don't initialize it->bidi_p for strings
9418 (reseat_to_string): Initialize it->bidi_p for strings here.
9419 (next_element_from_string, next_element_from_c_string)
9420 (next_element_from_buffer): Add xassert's for correspondence
9421 between IT's object being iterated and it->bidi_it.string
9423 (face_before_or_after_it_pos): Support bidi iteration.
9424 (next_element_from_c_string): Handle the case of the first string
9425 character that is not the first one in the visual order.
9426 (get_visually_first_element): New function, refactored from common
9427 parts of next_element_from_buffer, next_element_from_string, and
9428 next_element_from_c_string.
9429 (tool_bar_lines_needed, redisplay_tool_bar)
9430 (display_menu_bar): Force left-to-right direction. Add a FIXME
9431 comment for making that be controlled by a user option.
9432 (push_it, pop_it): Save and restore the state of the
9433 bidi iterator. Save and restore the bidi_p flag.
9434 (pop_it): Iterate out of display property for string iteration as
9436 (iterate_out_of_display_property): Support iteration over strings.
9437 (handle_single_display_spec): Set up it->bidi_it for iteration
9438 over a display string, and call bidi_init_it.

9441 iterator for displaying display or overlay strings.
9442 (forward_to_next_line_start): Don't use the shortcut if
9444 (back_to_previous_visible_line_start): If handle_display_prop
9445 pushed the iterator stack, restore the internal state of the bidi
9446 iterator by calling bidi_pop_it same number of times.
9447 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9448 and we are bidi-iterating, don't decrement the iterator position;
9449 instead, set the first_elt flag in the bidi iterator, to produce
9451 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9452 (push_display_prop): xassert that we are iterating a buffer.
9453 (push_it, pop_it): Save and restore paragraph_embedding member.
9454 (handle_single_display_spec, next_overlay_string)
9455 (get_overlay_strings_1, reseat_1, reseat_to_string)
9456 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9457 correctly. Don't assume unibyte strings are not bidi-reordered.
9458 (compute_display_string_pos)
9459 (compute_display_string_end): Fix handling the case of C string.
9460 (push_it, pop_it): Save and restore from_disp_prop_p.
9461 (handle_single_display_spec, push_display_prop): Set the
9462 from_disp_prop_p flag.
9463 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9465 popping after iteration over a string that came from a display
9466 property. Fix a typo in popping stretch info. Add an assertion
9467 for verifying that the iterator position is in sync with the bidi
9469 (handle_single_display_spec, get_overlay_strings_1)
9470 (push_display_prop): Fix initialization of paragraph direction for
9471 string when that of the parent object is not yet determined.

9473 iterator with IT's position. (Bug#7616)
9474 (find_row_edges): If ROW->start.pos gives position
9475 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

9484 saving a temporary copy of the iterator and restoring it back.
9485 (back_to_previous_visible_line_start, reseat_1)
9486 (init_iterator): Empty the bidi cache "stack".
9487 (move_it_in_display_line_to): If iterator ended up at
9488 EOL, but we never saw any buffer positions smaller than
9489 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9490 motion in bidi-reordered lines.
9491 (move_it_in_display_line_to): Record prev_method and prev_pos
9492 immediately before the call to set_iterator_to_next. Fixes cursor
9493 motion in bidi-reordered lines with stretch glyphs and strings
9494 displayed in margins. (Bug#8133) (Bug#8867)
9495 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9497 (pos_visible_p): Support positions in bidi-reordered lines.
9498 Save and restore bidi cache.
9500 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9501 (bidi_paragraph_info): Delete unused struct.
9502 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9503 (bidi_cache_start): New variable.

9509 (bidi_level_of_next_char, bidi_find_other_level_edge)
9510 (bidi_move_to_visually_next): Compare cache index with
9511 bidi_cache_start rather than with zero.
9512 (bidi_fetch_char): Accept new argument STRING; all callers
9513 changed. Support iteration over a string. Support strings with
9514 display properties. Support unibyte strings. Fix the type of
9515 `len' according to what STRING_CHAR_AND_LENGTH expects.
9516 (bidi_paragraph_init, bidi_resolve_explicit_1)
9517 (bidi_resolve_explicit, bidi_resolve_weak)

9525 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
9526 Call it instead of FETCH_MULTIBYTE_CHAR.

9528 initialized to valid values.
9529 (bidi_init_it): Don't initialize charpos and bytepos with invalid
9531 (bidi_level_of_next_char): Allow the sentinel "position" to pass
9532 the test for valid cached positions. Fix the logic for looking up
9533 the sentinel state in the cache. GCPRO the Lisp string we are
9535 (bidi_push_it, bidi_pop_it): New functions.
9536 (bidi_initialize): Initialize the bidi cache start stack pointer.
9537 (bidi_cache_ensure_space): New function, refactored from part of

9541 (bidi_count_bytes, bidi_char_at_pos): New functions.
9542 (bidi_cache_search): Don't assume bidi_cache_last_idx is
9543 always valid if bidi_cache_idx is valid.

9923 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9924 subseconds part to the entropy, as that's a bit more random.
9925 Prefer signed to unsigned, since the signedness doesn't matter and
9926 in general we prefer signed. When given a limit, use a
9927 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9928 latter isn't right if USE_2_TAGS_FOR_INTS.

9947 * buffer.c (Foverlay_put): Say what the return value is
9950 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9954 error be more correct.
9956 * fns.c (Frequire): Remove the mention of the .gz files, since

9973 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

10075 * eval.c (struct backtrace): Simplify and port the data structure.
10076 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10077 signed bit field, as this assumption is not portable and it makes
10078 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10079 "char debug_on_exit : 1" as this is not portable either; instead,
10080 use the portable "unsigned int debug_on_exit : 1". Remove unused
10081 member evalargs. Remove obsolete comments about cc bombing out.
10083 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
10085 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

10153 (emacs_fixed_get_preferred_height): Use min_width/height from
10154 frames size_hint to set minimum and natural (Bug#8919).
10155 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10156 and use min_width/height from frames size_hint to set
10157 min_width/height (Bug#8919).

10177 Use gnulib's dup2 module instead of rolling our own.
10178 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

10245 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10247 Integer and buffer overflow fixes (Bug#8873).
10249 * print.c (printchar, strout): Check for string overflow.
10250 (PRINTPREPARE, printchar, strout):
10251 Don't set size unless allocation succeeds.
10253 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10254 for sizes. Check for string overflow more accurately.
10255 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.

10258 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10259 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10263 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10265 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10267 * lread.c: Integer overflow fixes.
10268 (read_integer): Radix is now EMACS_INT, not int,
10269 to improve quality of diagnostics for out-of-range radices.
10270 Calculate buffer size correctly for out-of-range radices.
10271 (read1): Check for integer overflow in radices, and in
10272 read-circle numbers.
10273 (read_escape): Avoid int overflow.
10274 (Fload, openp, read_buffer_size, read1)
10275 (substitute_object_recurse, read_vector, read_list, map_obarray):
10276 Use ptrdiff_t, not int, for sizes.

10291 2011-06-22 Leo Liu <sdl.web@gmail.com>
10293 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10294 Move to minibuffer.el.
10296 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10298 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10299 The following patches are for when GLYPH_DEBUG && !XASSERT.
10300 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10301 * dispnew.c (flush_stdout):
10302 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10303 Mark as externally visible.
10304 * dispnew.c (check_window_matrix_pointers): Now static.
10305 * dispnew.c (window_to_frame_vpos):
10306 * xfns.c (unwind_create_frame):
10307 * xterm.c (x_check_font): Remove unused local.
10308 * scroll.c (CHECK_BOUNDS):
10309 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10310 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10311 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10312 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10313 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10315 (debug_method_add): Use va_list and vsprintf rather than relying
10316 on undefined behavior with wrong number of arguments.
10317 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10318 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10319 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10320 since we're not interested in debugging glyphs with old libraries.
10321 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10322 GCC 4.6.0's static checking.
10324 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10326 Integer overflow and signedness fixes (Bug#8873).

10338 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10340 * xfaces.c (load_pixmap):
10341 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10342 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10343 (.bitmaps_last, struct x_output.icon_bitmap):
10344 Use ptrdiff_t, not int, for bitmap indexes.
10345 (x_allocate_bitmap_record): Check for size overflow.
10346 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10348 Use ptrdiff_t, not int, for overlay counts.
10349 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10350 * editfns.c (overlays_around, get_pos_property):

10358 Use ptrdiff_t, not int, for sizes.
10359 (overlays_at, overlays_in): Check for size-calculation overflow.
10361 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10363 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10364 (x_session_initialize): Do not assume string length fits in int.
10366 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10367 This is unlikely, but can occur if DPI is outlandish.
10369 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10370 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10372 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10373 * xrdb.c (magic_file_p, search_magic_path):
10374 Omit last arg SUFFIX; it was always 0. All callers changed.
10375 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10377 * xfont.c (xfont_match): Avoid need for strlen.
10379 * xfns.c: Don't assume strlen fits in int.

10382 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10383 not unsigned long, as we prefer signed integers. All callers changed.
10384 Detect integer overflow in repeat count.
10385 (message_dolog): Don't assume print length fits in 39 bytes.
10386 (display_mode_element): Don't assume strlen fits in int.
10388 * termcap.c: Don't assume sizes fit in int and never overflow.
10389 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.

10392 * minibuf.c (Fread_buffer):
10393 * lread.c (intern, intern_c_string):
10394 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

10407 * filelock.c: Fix some buffer overrun and integer overflow issues.
10408 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10409 Reformulate so as not to need the command string.
10410 Invoke gzip -cd rather than gunzip, as it's more portable.
10411 (lock_info_type, lock_file_1, lock_file):
10412 Don't assume pid_t and time_t fit in unsigned long.
10413 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10414 (current_lock_owner): Prefer signed type for sizes.
10415 Use memcpy, not strncpy, where memcpy is what is really wanted.
10416 Don't assume (via atoi) that time_t and pid_t fit in int.
10417 Check for time_t and/or pid_t out of range, e.g., via a network share.
10418 Don't alloca where an auto var works fine.
10420 * fileio.c: Fix some integer overflow issues.
10421 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10422 Don't assume string length fits in int.
10423 (directory_file_name): Don't assume string length fits in long.
10424 (make_temp_name): Don't assume pid fits in int, or that its print
10425 length is less than 20.
10427 * data.c (Fsubr_name): Rewrite to avoid a strlen call.

10444 (Fgetenv_internal):
10445 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10447 * lread.c (invalid_syntax): Omit length argument.
10448 All uses changed. This doesn't fix a bug, but it simplifies the
10449 code away from its former Hollerith-constant appearance, and it's
10450 one less 'int' to worry about when looking at integer-overflow issues.
10451 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10453 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10454 This didn't break anything, but it didn't help either.
10455 It's confusing to put a bogus integer in a place where the actual
10456 value does not matter.
10457 (LIST_END_P): Remove unused macro and its bogus comment.
10458 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10460 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10461 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10463 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10464 We prefer signed types, and the value cannot exceed the EMACS_INT
10465 range anyway (because otherwise the length would not be representable).
10466 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10467 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10468 This avoids a GCC warning when WIDE_EMACS_INT.
10470 * indent.c (sane_tab_width): New function.
10471 (current_column, scan_for_column, Findent_to, position_indentation)
10472 (compute_motion): Use it. This is just for clarity.
10473 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10475 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10477 * lisp.h (lint_assume): New macro.
10478 * composite.c (composition_gstring_put_cache):
10479 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10481 * editfns.c, insdel.c:
10482 Omit unnecessary forward decls, to simplify future changes.
10484 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10486 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10488 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10489 Use much-faster test for byte-length change.
10490 Don't assume string byte-length fits in 'int'.
10491 Check that character arg fits in 'int'.
10492 (mapcar1): Declare byte as byte, for clarity.
10494 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10496 * fns.c (concat): Catch string overflow earlier.
10497 Do not rely on integer wraparound.
10499 * dispextern.h (struct it.overlay_strings_charpos)
10500 (struct it.selective): Now EMACS_INT, not int.
10501 * xdisp.c (forward_to_next_line_start)
10502 (back_to_previous_visible_line_start)
10503 (reseat_at_next_visible_line_start, next_element_from_buffer):
10504 Don't arbitrarily truncate the value of 'selective' to int.
10506 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10508 * composite.c: Don't truncate sizes to 'int'.
10509 (composition_gstring_p, composition_reseat_it)
10510 (composition_adjust_point): Use EMACS_INT, not int.
10511 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10512 not EMACS_UINT, for indexes.
10514 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10516 * buffer.c: Include <verify.h>.
10517 (struct sortvec.priority, struct sortstr.priority):
10518 Now EMACS_INT, not int.
10519 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10520 (struct sortstr.size, record_overlay_string)
10521 (struct sortstrlist.size, struct sortlist.used):
10522 Don't truncate size to int.
10523 (record_overlay_string): Check for size-calculation overflow.
10524 (init_buffer_once): Check at compile-time, not run-time.
10526 2011-06-22 Jim Meyering <meyering@redhat.com>
10528 Don't leak an XBM-image-sized buffer
10529 * image.c (xbm_load): Free the image buffer after using it.
10531 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10534 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10535 that Sun C diagnosed.
10536 * fns.c (secure_hash): Fix pointer signedness issue.
10537 * intervals.c (static_offset_intervals): New function.
10538 (offset_intervals): Use it.
10540 2011-06-21 Leo Liu <sdl.web@gmail.com>
10543 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10546 * fns.c (secure_hash): Rename from crypto_hash_function and change
10547 the first arg to accept symbols.
10548 (Fsecure_hash): New primitive.
10549 (syms_of_fns): New symbols.
10551 2011-06-20 Deniz Dogan <deniz@dogan.se>
10553 * process.c (Fset_process_buffer): Clarify return value in
10556 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10558 * dispnew.c (add_window_display_history): Use BVAR.
10560 * xdisp.c (debug_method_add): Use BVAR.
10561 (check_window_end, dump_glyph_matrix, dump_glyph)
10562 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10564 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10567 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10568 check till after the cache is created in init_frame_faces.
10570 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10572 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10574 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10576 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10577 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10578 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10580 Improve buffer-overflow checking (Bug#8873).
10581 * fileio.c (Finsert_file_contents):
10582 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10583 Remove the old (too-loose) buffer overflow checks.
10584 They weren't needed, since make_gap checks for buffer overflow.
10585 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10586 The old code merely checked for Emacs fixnum overflow, and relied
10587 on undefined (wraparound) behavior. The new code avoids undefined
10588 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10590 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10591 Tune. Don't use wider integers than needed. Don't use alloca.
10592 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10594 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10596 * insdel.c, lisp.h (buffer_overflow): New function.
10597 (insert_from_buffer_1, replace_range, replace_range_2):
10598 * insdel.c (make_gap_larger):
10599 * editfns.c (Finsert_char):
10600 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10602 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10604 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10606 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10608 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10609 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10611 * fileio.c: Don't assume EMACS_INT fits in off_t.
10612 (emacs_lseek): New static function.
10613 (Finsert_file_contents, Fwrite_region): Use it.
10614 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10616 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10618 * fns.c: Don't overflow int when computing a list length.
10619 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10620 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10621 truncation on 64-bit hosts. Check for QUIT every
10622 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10623 faster and is responsive enough.
10624 (Flength): Report an error instead of overflowing an integer.
10625 (Fsafe_length): Return a float if the value is not representable
10626 as a fixnum. This shouldn't happen except in contrived situations.
10627 (Fnthcdr, Fsort): Don't assume list length fits in int.
10628 (Fcopy_sequence): Don't assume vector length fits in int.
10630 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10631 (header_size, word_size): New constants.
10632 (allocate_vectorlike): Don't check size overflow here.
10633 (allocate_vector): Check it here instead, since this is the only
10634 caller of allocate_vectorlike that could cause overflow.
10635 Check that the new vector's length is representable as a fixnum.
10637 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10638 The previous code was bogus. For example, next_almost_prime (32)
10639 returned 39, which is undesirable as it is a multiple of 3; and
10640 next_almost_prime (24) returned 25, which is a multiple of 5 so
10641 why was the code bothering to check for multiples of 7?
10643 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10645 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10647 Variadic C functions now count arguments with ptrdiff_t.
10648 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10649 Back then I didn't know that the Emacs coding style prefers signed int.
10650 Also, in the meantime I found a few more instances where arguments
10651 were being counted with int, which may truncate counts on 64-bit
10652 machines, or EMACS_INT, which may be unnecessarily wide.
10653 * lisp.h (struct Lisp_Subr.function.aMANY)
10654 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10655 Arg counts are now ptrdiff_t, not size_t.
10656 All variadic functions and their callers changed accordingly.
10657 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10658 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10659 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10660 * callint.c (Fcall_interactively): Check arg count for overflow,
10661 to avoid potential buffer overrun. Use signed char, not 'int',
10662 for 'varies' array, so that we needn't bother to check its size
10663 calculation for overflow.
10664 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10665 * eval.c (apply_lambda):
10666 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10667 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10668 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10670 * callint.c (Fcall_interactively): Don't use index var as event count.
10672 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10673 * mem-limits.h (SIZE): Remove; no longer used.
10675 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10677 Remove unnecessary casts.
10678 * xterm.c (x_term_init):
10679 * xfns.c (x_set_border_pixel):
10680 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10681 These aren't needed now that we assume ANSI C.
10683 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10684 It's more likely to cause problems (due to unsigned overflow)
10687 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10689 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10691 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10693 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10695 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10697 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10699 GLYPH_CODE_FACE returns EMACS_INT, not int.
10700 * dispextern.h (merge_faces):
10701 * xfaces.c (merge_faces):
10702 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10703 Don't assume EMACS_INT fits in int.
10705 * character.h (CHAR_VALID_P): Remove unused parameter.
10706 * fontset.c, lisp.h, xdisp.c: All uses changed.
10708 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10710 * fns.c (concat): Minor tuning based on overflow analysis.
10711 This doesn't fix any bugs. Use int to hold character, instead
10712 of constantly refetching from Emacs object. Use XFASTINT, not
10713 XINT, for value known to be a character. Don't bother comparing
10714 a single byte to 0400, as it's always less.
10716 * floatfns.c (Fexpt):
10717 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10719 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10722 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10724 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10725 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10726 incorrectly succeed when S was a string, because 4294967386 was
10727 truncated before it was used.
10729 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10730 Otherwise, an out-of-range integer could cause undefined behavior
10733 * composite.c: Use int, not EMACS_INT, for characters.
10734 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10735 EMACS_INT, for values that are known to be in character range.
10736 This doesn't fix any bugs but is the usual style inside Emacs and
10737 may generate better code on 32-bit machines.
10739 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10740 This is for reasons similar to the recent CHAR_STRING fix.
10741 * charset.c (Fencode_char): Check that character arg is actually
10742 a character. Pass an int to ENCODE_CHAR.
10743 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10744 wider than 'int', as a compile-time check to prevent future regressions
10747 * character.c (char_string): Remove unnecessary casts.
10749 Make sure a 64-bit char is never passed to CHAR_STRING.
10750 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10751 by silently ignoring the top 32 bits, allowing some values
10752 that were far too large to be valid characters.
10753 * character.h: Include <verify.h>.
10754 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10755 arguments are no wider than unsigned, as a compile-time check
10756 to prevent future regressions in this area.
10758 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10759 (Fsubst_char_in_region):
10761 * xdisp.c (decode_mode_spec_coding):
10762 Adjust to CHAR_STRING's new requirement.
10763 * editfns.c (Finsert_char, Fsubst_char_in_region):
10764 * fns.c (concat): Check that character args are actually
10765 characters. Without this test, these functions did the wrong
10766 thing with wildly out-of-range values on 64-bit hosts.
10768 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10769 These casts should not be needed on 32-bit hosts, either.
10770 * keyboard.c (read_char):
10771 * lread.c (Fload): Remove casts to unsigned.
10773 * lisp.h (UNSIGNED_CMP): New macro.
10774 This fixes comparison bugs on 64-bit hosts.
10775 (ASCII_CHAR_P): Use it.
10776 * casefiddle.c (casify_object):
10777 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10778 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10779 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10780 * dispextern.h (FACE_FROM_ID):
10781 * keyboard.c (read_char): Use UNSIGNED_CMP.
10783 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10784 not to EMACS_INT, to avoid GCC warning.
10786 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10788 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10789 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10790 isn't needed on 32-bit machines.
10792 * buffer.c (Fgenerate_new_buffer_name):
10793 Use EMACS_INT for count, not int.
10794 (advance_to_char_boundary): Return EMACS_INT, not int.
10796 * data.c (Qcompiled_function): Now static.
10798 * window.c (window_body_lines): Now static.
10800 * image.c (gif_load): Rename local to avoid shadowing.
10802 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10803 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10804 * alloc.c (make_save_value): Integer argument is now of type
10805 ptrdiff_t, not int.
10806 (mark_object): Use ptrdiff_t, not int.
10807 * lisp.h (pD): New macro.
10808 * print.c (print_object): Use it.
10810 * alloc.c: Use EMACS_INT, not int, to count objects.
10811 (total_conses, total_markers, total_symbols, total_vector_size)
10812 (total_free_conses, total_free_markers, total_free_symbols)
10813 (total_free_floats, total_floats, total_free_intervals)
10814 (total_intervals, total_strings, total_free_strings):
10815 Now EMACS_INT, not int. All uses changed.
10816 (Fgarbage_collect): Compute overall total using a double, so that
10817 integer overflow is less likely to be a problem. Check for overflow
10818 when converting back to an integer.
10819 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10820 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10821 These were 'int' variables that could overflow on 64-bit hosts;
10822 they were never used, so remove them instead of repairing them.
10823 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10824 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10825 Previously, this ceilinged at INT_MAX, but that doesn't work on
10827 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10829 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10830 (allocate_vectorlike): Check for ptrdiff_t overflow.
10831 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10832 when a (possibly-narrower) signed value would do just as well.
10833 We prefer using signed arithmetic, to avoid comparison confusion.
10835 * alloc.c: Catch some string size overflows that we were missing.
10836 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10837 for convenience in STRING_BYTES_MAX.
10838 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10839 The definition here is exact; the one in lisp.h was approximate.
10840 (allocate_string_data): Check for string overflow. This catches
10841 some instances we weren't catching before. Also, it catches
10842 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10843 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10844 and ptrdiff_t and EMACS_INT are both 64 bits.
10846 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10847 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10848 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10850 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10852 * alloc.c (Fmake_string): Check for out-of-range init.
10854 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10856 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10858 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10860 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10861 xg_get_default_scrollbar_width.
10863 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10864 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10865 (style_changed_cb): Call update_theme_scrollbar_width and call
10866 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10867 all frames (Bug#8505).
10868 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10869 Call gtk_window_set_resizable if HAVE_GTK3.
10870 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10871 and height if HAVE_GTK3 (Bug#8505).
10872 (scroll_bar_width_for_theme): New variable.
10873 (update_theme_scrollbar_width): New function.
10874 (xg_get_default_scrollbar_width): Move code to
10875 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10876 (xg_initialize): Call update_theme_scrollbar_width.
10878 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10880 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10882 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10884 * frame.c (make_frame): Call other_buffer_safely instead of
10887 * window.c (temp_output_buffer_show): Call display_buffer with
10888 second argument Vtemp_buffer_show_specifiers and reset latter
10889 immediately after the call.
10890 (Vtemp_buffer_show_specifiers): New variable.
10891 (auto_window_vscroll_p, next_screen_context_lines)
10892 (Vscroll_preserve_screen_position): Remove leading asterisks from
10895 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10897 Fix minor problems found by GCC 4.6.0 static checking.
10898 * buffer.c (Qclone_number): Remove for now, as it's unused.
10899 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10900 (record_buffer): Remove unused local.
10901 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10902 (set_frame_buffer_list): Remove; unused.

11347 (Fselected_window, select_window, Fselect_window): Move up in
11348 code. Minor doc-string fixes.
11350 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
11352 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
11353 Do not assume that spare memory exists; that assumption is valid
11354 only if SYSTEM_MALLOC.
11355 (LARGE_REQUEST): New macro, so that the issue of large requests
11356 is separated from the issue of spare memory.
11358 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
11360 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

11375 min width by calling x_set_scroll_bar_default_width (Bug#8505).
11377 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
11379 * xdisp.c (single_display_spec_intangible_p): Remove declaration.

11384 (x_clipboard_manager_save): Add return value.
11385 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
11386 New error handlers.
11387 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
11388 Obey Vx_select_enable_clipboard_manager. Catch errors in
11389 x_clipboard_manager_save (Bug#8779).
11390 (Vx_select_enable_clipboard_manager): New variable.
11391 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11393 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11395 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11397 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11399 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11400 in the current matrix if keep_current_p is non-zero.

11404 * bidi.c (bidi_level_of_next_char): Fix last change.
11406 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11408 Support bidi reordering of text covered by display properties.
11410 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11411 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11412 (bidi_cache_search, bidi_cache_iterator_state)
11413 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11414 (bidi_level_of_next_char, bidi_move_to_visually_next):
11415 Support character positions inside a run of characters covered by a
11417 (bidi_paragraph_init, bidi_resolve_explicit_1)
11418 (bidi_level_of_next_char): Call bidi_fetch_char and
11419 bidi_fetch_char_advance instead of FETCH_CHAR and
11420 FETCH_CHAR_ADVANCE.
11421 (bidi_init_it): Initialize new members.
11422 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11424 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11425 instead of using explicit *_CHAR codes.
11426 (bidi_resolve_explicit, bidi_resolve_weak):
11427 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11428 bidirectional text is supported only in multibyte buffers.
11429 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11430 it to initialize the frame_window_p member of struct bidi_it.
11431 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11432 (bidi_resolve_explicit, bidi_resolve_weak)

11434 bidi_it->nchars is non-positive.
11435 (bidi_level_of_next_char): Don't try to lookup the cache for the
11436 next/previous character if nothing is cached there yet, or if we
11437 were just reseat()'ed to a new position.
11439 * xdisp.c (set_cursor_from_row): Set start and stop points
11440 according to the row's direction when priming the loop that looks
11441 for the glyph on which to display cursor.
11442 (single_display_spec_intangible_p): Function deleted.
11443 (display_prop_intangible_p): Reimplement to call
11444 handle_display_spec instead of single_display_spec_intangible_p.
11445 Accept 3 additional arguments needed by handle_display_spec.
11446 This fixes incorrect cursor motion across display property with complex
11447 values: lists, `(when COND...)' forms, etc.
11448 (single_display_spec_string_p): Support property values that are
11449 lists with the argument STRING its top-level element.
11450 (display_prop_string_p): Fix the condition for processing a
11451 property that is a list to be consistent with handle_display_spec.
11452 (handle_display_spec): New function, refactored from the
11453 last portion of handle_display_prop.
11454 (compute_display_string_pos): Accept additional argument
11455 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11456 value of a `display' property is a "replacing spec".
11457 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11458 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11459 the display property, but just return a value indicating whether
11460 the display property will replace the characters it covers.
11461 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11462 frame_window_p members of struct bidi_it.
11463 (compute_display_string_pos, compute_display_string_end):
11465 (push_it): Accept second argument POSITION, where pop_it should
11466 jump to continue iteration.
11467 (reseat_1): Initialize bidi_it.disp_pos.
11469 * keyboard.c (adjust_point_for_property): Adjust the call to
11470 display_prop_intangible_p to its new signature.
11472 * dispextern.h (struct bidi_it): New member frame_window_p.
11473 (bidi_init_it): Update prototypes.
11474 (display_prop_intangible_p): Update prototype.
11475 (compute_display_string_pos, compute_display_string_end):
11476 Declare prototypes.
11477 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11480 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11482 Malloc failure behavior now depends on size of allocation.
11483 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11484 * lisp.h: Change signatures accordingly.
11485 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11486 All callers changed. (Bug#8762)
11488 * gnutls.c: Use Emacs's memory allocators.
11489 Without this change, the gnutls library would invoke malloc etc.
11490 directly, which causes problems on non-SYNC_INPUT hosts, and which
11491 runs afoul of improving memory_full behavior. (Bug#8761)
11492 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11493 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11494 xfree instead of the default malloc, realloc, free.
11495 (Fgnutls_boot): No need to check for memory allocation failure,
11496 since xmalloc does that for us.
11498 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11499 * category.c (hash_get_category_set):
11500 * ccl.c (ccl_driver):
11501 * charset.c (Fdefine_charset_internal):
11502 * charset.h (struct charset.hash_index):
11503 * composite.c (get_composition_id, gstring_lookup_cache)
11504 (composition_gstring_put_cache):
11505 * composite.h (struct composition.hash_index):
11506 * dispextern.h (struct image.hash):
11507 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11508 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11509 (hashfn_equal, hashfn_user_defined, make_hash_table)
11510 (maybe_resize_hash_table, hash_lookup, hash_put)
11511 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11512 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11513 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11514 * image.c (make_image, search_image_cache, lookup_image)
11515 (xpm_put_color_table_h):
11516 * lisp.h (struct Lisp_Hash_Table):
11517 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11518 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11519 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11520 * alloc.c (allocate_vectorlike):
11521 Check for overflow in vector size calculations.
11522 * ccl.c (ccl_driver):
11523 Check for overflow when converting EMACS_INT to int.
11524 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11525 need to be updated by these changes.
11526 * fns.c (make_hash_table, maybe_resize_hash_table):
11527 Check for integer overflow with large hash tables.
11528 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11529 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11530 (SXHASH_REDUCE): New macro.
11531 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11532 Use it instead of discarding useful hash info with large hash values.
11533 (sxhash_float): New function.
11534 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11535 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11536 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11537 Rewrite to use FIXNUM_BITS, as this simplifies things.
11538 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11539 Adjust signatures to match updated version of code.
11540 (consing_since_gc): Now EMACS_INT, since a single hash table can
11541 use more than INT_MAX bytes.
11543 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11545 Make it possible to build with GCC-4.6+ -O2 -flto.
11547 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11549 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11551 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11552 Call minibuffer-inactive-mode.
11554 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11556 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11557 Update dependencies.
11559 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11561 * data.c (init_data): Remove code for UTS, this system is not
11564 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11566 Don't force ./temacs to start in terminal mode.
11568 * frame.c (make_initial_frame): Initialize faces in all cases, not
11569 only when CANNOT_DUMP is defined.
11570 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11572 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11574 * dispnew.c (add_window_display_history): Use const for the string
11575 pointer. Remove declaration, not needed.
11577 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11579 Use 'inline', not 'INLINE'.
11580 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11581 * alloc.c, fontset.c (INLINE): Remove.
11582 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11583 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11584 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11585 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11586 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11588 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11590 Make it possible to run ./temacs.
11592 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11593 syms_of_callproc does the same thing. Remove test for
11594 "initialized", do it in the caller.
11595 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11597 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11599 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11600 (read_minibuf): Use get_minibuffer.
11601 (syms_of_minibuf): Use DEFSYM.
11602 (Qmetadata): New var.
11603 * data.c (Qbuffer): Don't make it static.
11604 (syms_of_data): Use DEFSYM.
11606 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11608 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11609 (CCL_CODE_MIN): New macro.
11611 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11613 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11615 * eval.c (Qdebug): Now static.
11616 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11617 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11618 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11620 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11622 * image.c: Various fixes to ImageMagick code comments.
11623 (Fimagemagick_types): Doc fix.
11625 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11627 Minor fixes prompted by GCC 4.6.0 warnings.
11629 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11631 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11632 (x_clipboard_manager_save_all): Move extern decl to ...
11633 * xterm.h: ... here, so that it can be checked for consistency.
11635 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11637 * xselect.c (x_clipboard_manager_save_frame)
11638 (x_clipboard_manager_save_all): New functions.
11639 (Fx_clipboard_manager_save): Lisp function deleted.
11641 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11642 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11644 * xterm.h: Update prototype.
11646 2011-05-28 William Xu <william.xwl@gmail.com>
11648 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11649 exiting (Bug#8239).
11651 2011-05-28 Jim Meyering <meyering@redhat.com>
11653 Avoid a sign-extension bug in crypto_hash_function.
11654 * fns.c (to_uchar): Define.
11655 (crypto_hash_function): Use it to convert some newly-signed
11656 variables to unsigned, to avoid sign-extension bugs. For example,
11657 without this change, (md5 "truc") would evaluate to
11658 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11659 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11660 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11662 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11664 Integer overflow fixes.
11666 * dbusbind.c: Serial number integer overflow fixes.
11667 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11668 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11669 to hold a serial number that is too large for a fixnum.
11670 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11671 Check for serial numbers out of range. Decode any serial number
11672 that was so large that it became a float. (Bug#8722)
11674 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11675 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11676 Use XFASTINT rather than XUINT when numbers are nonnegative.
11677 (xd_append_arg, Fdbus_method_return_internal):
11678 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11679 arguments, check that Lisp number is nonnegative, rather than
11680 silently wrapping negative numbers around. (Bug#8722)
11681 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11684 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11686 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11688 ccl: Add integer overflow checks.
11689 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11690 (IN_INT_RANGE): New macros.
11691 (ccl_driver): Use them to check for integer overflow when
11692 decoding a CCL program. Many of the new checks are whether XINT (x)
11693 fits in int; it doesn't always, on 64-bit hosts. The new version
11694 doesn't catch all possible integer overflows, but it's an
11695 improvement. (Bug#8719)
11697 * alloc.c (make_event_array): Use XINT, not XUINT.
11698 There's no need for unsigned here.
11700 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11701 This follows up to the 2011-05-06 change that substituted uintptr_t
11702 for EMACS_INT. This case wasn't caught back then.
11704 Rework Fformat to avoid integer overflow issues.
11705 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11706 now (part of C89). Include <verify.h>.
11707 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11708 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11709 (Fformat): Avoid the prepass trying to compute sizes; it was only
11710 approximate and thus did not catch overflow reliably. Instead, walk
11711 through the format just once, formatting and computing sizes as we go,
11712 checking for integer overflow at every step, and allocating a larger
11713 buffer as needed. Keep track separately whether the format is
11714 multibyte. Keep only the most-recently calculated precision, rather
11715 than them all. Record whether each argument has been converted to
11716 string. Use EMACS_INT, not int, for byte and char and arg counts.
11717 Support field widths and precisions larger than INT_MAX. Avoid
11718 sprintf's undefined behavior with conversion specifications such as %#d
11719 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11720 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11721 formatting out-of-range floating point numbers with int
11722 formats. (Bug#8668)
11724 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11726 * data.c: Avoid integer truncation in expressions involving floats.
11727 * data.c: Include <intprops.h>.
11728 (arith_driver): When there's an integer overflow in an expression
11729 involving floating point, convert the integers to floating point
11730 so that the resulting value does not suffer from catastrophic
11731 integer truncation. For example, on a 64-bit host (* 4
11732 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11733 Do not rely on undefined behavior after integer overflow.
11735 merge count_size_as_multibyte, parse_str_to_multibyte
11736 * character.c, character.h (count_size_as_multibyte):
11737 Rename from parse_str_to_multibyte; all uses changed.
11738 Check for integer overflow.
11739 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11740 since it's now a duplicate of the other. This is more of
11741 a character than a buffer op, so better that it's in character.c.
11742 * fns.c, print.c: Adjust to above changes.
11744 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11746 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11748 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11750 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11751 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11752 (x_clipboard_manager_save): Now static.
11753 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11755 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11756 (crypto_hash_function): Now static.
11757 Fix pointer signedness problems. Avoid unnecessary initializations.
11759 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11761 * termhooks.h (Vselection_alist): Make it terminal-local.
11763 * terminal.c (create_terminal): Initialize it.
11765 * xselect.c: Support for clipboard managers.
11766 (Vselection_alist): Move to termhooks.h as terminal-local var.
11767 (LOCAL_SELECTION): New macro.
11768 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11769 (symbol_to_x_atom): Remove gratuitous arg.
11770 (x_handle_selection_request, lisp_data_to_selection_data)
11771 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11772 (x_own_selection, x_get_local_selection, x_convert_selection):
11773 New arg, specifying work frame. Use terminal-local Vselection_alist.
11774 (some_frame_on_display): Delete unused function.
11775 (Fx_own_selection_internal, Fx_get_selection_internal)
11776 (Fx_disown_selection_internal, Fx_selection_owner_p)
11777 (Fx_selection_exists_p): New optional frame arg.
11778 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11779 (x_handle_selection_clear): Don't treat other terminals with the
11780 same keyboard specially. Use the terminal-local Vselection_alist.
11781 (x_clear_frame_selections): Use Frun_hook_with_args.
11783 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11785 * xterm.h: Add support for those atoms.
11787 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11789 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11790 (converted_selections, conversion_fail_tag): New global variables.
11791 (x_selection_request_lisp_error): Free the above.
11792 (x_get_local_selection): Remove unnecessary code.
11793 (x_reply_selection_request): Args changed; handle arbitrary array
11794 of converted selections stored in converted_selections.
11795 Separate the XChangeProperty and SelectionNotify steps.
11796 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11797 (x_convert_selection): New function.
11798 (x_handle_selection_event): Simplify.
11799 (x_get_foreign_selection): Don't ignore incoming requests while
11800 waiting for an answer; this will fail when we implement
11801 SAVE_TARGETS, and seems unnecessary anyway.
11802 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11803 (Vx_sent_selection_functions): Doc fix.
11805 2011-05-26 Leo Liu <sdl.web@gmail.com>
11807 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11809 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11811 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11813 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11814 for fringe update if it has periodic bitmap.
11815 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11816 and fringe_bitmap_periodic_p.
11818 * fringe.c (get_fringe_bitmap_data): New function.
11819 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11820 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11821 row. Mark glyph row for fringe update if periodicity changed.
11823 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11824 for fringe update unless it has periodic bitmap.
11826 2011-05-25 Kenichi Handa <handa@m17n.org>
11828 * xdisp.c (get_next_display_element): Set correct it->face_id for
11829 a static composition.
11831 2011-05-24 Leo Liu <sdl.web@gmail.com>
11834 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11836 * fns.c (crypto_hash_function, Fsha1): New function.
11837 (Fmd5): Use crypto_hash_function.
11838 (syms_of_fns): Add Ssha1.
11840 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11842 * gnutls.c: Remove unused macros.
11843 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11844 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11845 Remove macros that are defined and never used.
11846 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11848 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11850 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11851 (Fx_get_selection_internal): Minor cleanup.
11852 (Fx_own_selection_internal): Rename arguments for consistency with
11855 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11857 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11859 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11861 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11863 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11865 * dispnew.c (scrolling_window): Don't exclude the case that the
11866 last enabled row in the desired matrix touches the bottom boundary.
11868 2011-05-21 Glenn Morris <rgm@gnu.org>
11870 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11871 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11872 and add some more files.
11874 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11876 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11877 report_file_error introduced by the change from 2011-05-07.
11879 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11881 * systime.h (Time): Define only if emacs is defined.
11882 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11883 where the include path doesn't have X11/X.h by default. See
11884 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11886 2011-05-20 Kenichi Handa <handa@m17n.org>
11888 * composite.c (find_automatic_composition): Fix previous change.
11890 2011-05-20 Glenn Morris <rgm@gnu.org>
11892 * lisp.mk: New file, split from Makefile.in.
11893 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11894 (shortlisp): Remove.
11895 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11897 2011-05-19 Glenn Morris <rgm@gnu.org>
11899 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11900 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11901 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11902 (lisp): Set the order to that of loadup.el.
11903 (shortlisp): Make it a copy of $lisp.
11904 (SOME_MACHINE_LISP): Remove.
11905 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11906 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11908 2011-05-18 Kenichi Handa <handa@m17n.org>
11910 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11911 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11912 (find_automatic_composition): Mostly rewrite for efficiency.
11914 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11916 * makefile.w32-in: Update dependencies.
11918 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11920 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11921 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11923 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11925 Fix some integer overflow issues, such as string length overflow.
11927 * insdel.c (count_size_as_multibyte): Check for string overflow.
11929 * character.c (lisp_string_width): Check for string overflow.
11930 Use EMACS_INT, not int, for string indexes and lengths; in
11931 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11932 the resulting string length overflows an EMACS_INT; instead,
11933 report a string overflow if no precision given. When checking for
11934 precision exhaustion, use a check that cannot possibly have
11935 integer overflow. (Bug#8675)
11936 * character.h (lisp_string_width): Adjust to new signature.
11938 * alloc.c (string_overflow): New function.
11939 (Fmake_string): Use it. This doesn't change behavior, but saves
11940 a few bytes and will simplify future changes.
11941 * character.c (string_escape_byte8): Likewise.
11942 * lisp.h (string_overflow): New decl.
11944 Fixups, following up to the user-interface timestamp change.
11945 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11946 for UI timestamps, instead of unsigned long.
11947 * msdos.c (mouse_get_pos): Likewise.
11948 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11949 * w32gui.h (Time): Define by including "systime.h" rather than by
11950 declaring it ourselves. (Bug#8664)
11952 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11953 * image.c (clear_image_cache): Likewise.
11955 * term.c (term_mouse_position): Don't assume time_t wraparound.
11957 Be more systematic about user-interface timestamps.
11958 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11959 and sometimes 'EMACS_UINT', to represent these timestamps.
11960 This change causes it to use 'Time' uniformly, as that's what X uses.
11961 This makes the code easier to follow, and makes it easier to catch
11962 integer overflow bugs such as Bug#8664.
11963 * frame.c (Fmouse_position, Fmouse_pixel_position):
11964 Use Time, not unsigned long, for user-interface timestamps.
11965 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11966 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11967 * keyboard.h (last_event_timestamp): Likewise.
11968 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11969 * menu.h (xmenu_show): Likewise.
11970 * term.c (term_mouse_position): Likewise.
11971 * termhooks.h (struct input_event.timestamp): Likewise.
11972 (struct terminal.mouse_position_hook): Likewise.
11973 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11974 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11975 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11976 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11977 what it was before.
11978 * menu.h, termhooks.h: Include "systime.h", for Time.
11980 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11981 Don't assume that the difference between two unsigned long values
11982 can fit into an integer. At this point, we know button_down_time
11983 <= event->timestamp, so the difference must be nonnegative, so
11984 there's no need to cast the result if double-click-time is
11985 nonnegative, as it should be; check that it's nonnegative, just in
11986 case. This bug is triggered when events are more than 2**31 ms
11987 apart (about 25 days). (Bug#8664)
11989 * xselect.c (last_event_timestamp): Remove duplicate decl.
11990 (x_own_selection): Remove needless cast to unsigned long.
11992 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11993 that always fit in int. Use a sentinel instead of a counter, to
11994 avoid a temp and to allay GCC's concerns about possible int overflow.
11995 * frame.h (struct frame): Use int for menu_bar_items_used
11996 instead of EMACS_INT, since it always fits in int.
11998 * menu.c (grow_menu_items): Check for int overflow.
12000 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12002 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12003 Before, the code was not consistent. These values cannot exceed
12004 2**31 - 1 so there's no need to make them unsigned.
12005 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12006 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12007 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12009 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12011 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12012 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12013 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12014 presumably because the widths might not match.
12016 * window.c (size_window): Avoid needless test at loop start.
12018 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12020 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12022 2011-05-12 Drew Adams <drew.adams@oracle.com>
12024 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12026 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12028 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12029 `width' to `bar_area_x' and `bar_area_width', respectively.
12030 (x_scroll_run): Take account of fringe background extension.
12032 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12033 Rename local vars `left' and `width' to `bar_area_x' and
12034 `bar_area_width', respectively.
12035 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12036 background extension.
12038 2011-05-10 Jim Meyering <meyering@redhat.com>
12040 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12042 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12044 * image.c (Finit_image_library): Return t for built-in image types,
12045 like pbm and xbm. (Bug#8640)
12047 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12049 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12051 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12053 * w32console.c (Fset_screen_color): Doc fix.
12054 (Fget_screen_color): New function.
12055 (syms_of_ntterm): Defsubr it.
12057 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12058 unlink the temporary file if Fcall_process didn't create it in the
12060 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12061 child process will be redirected to a file specified with `:file'.
12062 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12063 cue to call_process_cleanup not to close that handle.
12065 2011-05-07 Ben Key <bkey76@gmail.com>
12067 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12068 one of two shell specific rules, either bootstrap-temacs-CMD or
12069 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12070 to the previous implementation of the bootstrap-temacs rule.
12071 The bootstrap-temacs-CMD rule is similar to the previous
12072 implementation of the bootstrap-temacs rule except that it
12073 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12076 These changes, along with some changes to nt/configure.bat,
12077 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12078 earlier fix to add support for --cflags and --ldflags options
12079 that include quotes so that it works whether make uses cmd or
12082 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12084 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12085 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12087 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12088 a string. Handle both cases.
12089 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12090 (Fdbus_register_method): Use Qinvalid_function.
12092 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12094 * makefile.w32-in: Update dependencies.
12095 (LISP_H): Add inttypes.h and stdin.h.
12096 (PROCESS_H): Add unistd.h.
12098 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12100 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12101 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12103 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12105 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12107 * term.c (vfatal): Remove stray call to va_end.
12108 It's not needed and the C Standard doesn't allow it here anyway.
12110 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12111 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12113 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12116 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12118 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12120 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12122 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12124 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12126 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12127 * charset.c (Fdefine_charset_internal): Don't initialize
12128 charset.code_space[15]. The value was garbage, on hosts with
12129 32-bit int (Bug#8600).
12131 * lread.c (read_integer): Be more consistent with string-to-number.
12132 Use string_to_number to do the actual conversion; this avoids
12133 rounding errors and fixes some other screwups. Without this fix,
12134 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12135 (digit_to_number): Move earlier, for benefit of read_integer.
12136 Return -1 if the digit is out of range for the base, -2 if it is
12137 not a digit in any supported base. (Bug#8602)
12139 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12141 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12142 to match comment at start of function. This also removes a
12143 GCC warning about overflow in a 32+64-bit port.
12145 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12147 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12148 Reported by Stefan Monnier in
12149 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12150 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12151 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12153 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12154 (EMACS_UINTPTR): Likewise, with uintptr_t.
12156 * lisp.h: Prefer 64-bit EMACS_INT if available.
12157 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12158 on 32-bit hosts that have 64-bit int, so that they can access
12160 However, temporarily disable this change unless the temporary
12161 symbol WIDE_EMACS_INT is defined.
12163 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12165 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12166 This removes an assumption that EMACS_INT and long are the same
12167 width as pointers. The assumption is true for Emacs porting targets
12168 now, but we want to make other targets possible.
12169 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12170 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12171 In the rest of the code, change types of integers that hold casted
12172 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12173 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12174 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12175 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12176 No need to cast type when ORing.
12177 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12178 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12179 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12180 assume EMACS_INT is the same width as char *.
12181 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12182 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12183 Remove no-longer-needed casts.
12184 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12185 (xg_tool_bar_help_callback, xg_make_tool_item):
12186 Use EMACS_INTPTR to hold an integer
12187 that will be cast to void *; this can avoid a GCC warning
12188 if EMACS_INT is not the same width as void *.
12189 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12190 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12191 (current_message_1, set_message_1):
12192 Use a local to convert to proper width without a cast.
12193 * xmenu.c (dialog_selection_callback): Likewise.
12195 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12196 Also, don't assume VALBITS / RAND_BITS is less than 5,
12197 and don't rely on undefined behavior when shifting a 1 left into
12199 * lisp.h (get_random): Change signature to match.
12201 * lread.c (hash_string): Use size_t, not int, for hash computation.
12202 Normally we prefer signed values; but hashing is special, because
12203 it's better to use unsigned division on hash table sizes so that
12204 the remainder is nonnegative. Also, size_t is the natural width
12205 for hashing into memory. The previous code used 'int', which doesn't
12206 retain enough info to hash well into very large tables.
12207 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12209 * dbusbind.c: Don't possibly lose pointer info when converting.
12210 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12211 Use XPNTR rather than XHASH, so that the high-order bits of
12212 the pointer aren't lost when converting through void *.
12214 * eval.c (Fautoload): Don't double-shift a pointer.
12216 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

12305 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12307 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12308 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12311 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12313 * xterm.c (x_set_frame_alpha): Do not set property on anything

12353 rather than `XVECTOR (FOO)->size'.
12355 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12356 inttypes.h, as a gnulib replacement is used if it not available in
12359 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12361 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

12366 will grow beyond MOST_POSITIVE_FIXNUM.
12367 (decode_coding_emacs_mule): Abort if there isn't enough place in
12368 charbuf for the composition carryover bytes. Reserve an extra

12384 produced by %s or %c overflows available buffer space. (Bug#8545)
12386 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12388 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

12391 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12393 * w32.c (init_environment): Warn about defaulting HOME to C:\.

12397 * keyboard.c (Qdelayed_warnings_hook): Define.
12398 (command_loop_1): Run `delayed-warnings-hook'
12399 if Vdelayed_warnings_list is non-nil.
12400 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12401 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12403 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12405 * doprnt.c (doprnt): Don't return value smaller than the buffer
12406 size if the message was truncated. (Bug#8545).
12408 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12410 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

12417 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12419 * makefile.w32-in: Update dependencies.
12421 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12423 Improve `doprnt' and its usage. (Bug#8545)
12424 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12425 `format_end'. Remove support for %l as a conversion specifier.
12426 Don't use xrealloc. Improve diagnostics when the %l size modifier
12427 is used. Update the commentary.
12429 * eval.c (verror): Simplify calculation of size_t.
12431 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12434 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12436 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12439 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12441 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12442 This makes this file independent of the recent pseudovector change.
12444 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12446 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12448 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12449 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12450 Remove unused local.
12451 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12453 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12454 GCC 4.6.0 optimizes based on type-based alias analysis.
12455 For example, if b is of type struct buffer * and v of type struct
12456 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12457 != &v->size, and therefore "v->size = 1; b->size = 2; return
12458 v->size;" must therefore return 1. This assumption is incorrect
12459 for Emacs, since it type-puns struct Lisp_Vector * with many other
12460 types. To fix this problem, this patch adds a new type struct
12461 vectorlike_header that documents the constraints on layout of vectors
12462 and pseudovectors, and helps optimizing compilers not get fooled
12463 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12464 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12465 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12467 (XSETPVECTYPE): Rewrite in terms of new macro.
12468 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12469 This is a bit clearer, and further avoids the possibility of
12470 undesirable aliasing.
12471 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12472 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12473 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12474 since Lisp_Subr is a special case (no "next" field).
12475 (ASIZE): Now uses header.size rather than size.
12476 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12477 to avoid the hassle of writing XVECTOR (foo)->header.size.
12478 (struct vectorlike_header): New type.
12479 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12480 object, to help avoid aliasing.
12481 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12482 (SUBRP): Likewise, since Lisp_Subr is a special case.
12483 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12484 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12485 (struct Lisp_Hash_Table): Combine first two members into a single
12486 struct vectorlike_header member. All uses of "size" and "next" members
12487 changed to be "header.size" and "header.next".
12488 * buffer.h (struct buffer): Likewise.
12489 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12490 * frame.h (struct frame): Likewise.
12491 * process.h (struct Lisp_Process): Likewise.
12492 * termhooks.h (struct terminal): Likewise.
12493 * window.c (struct save_window_data, struct saved_window): Likewise.
12494 * window.h (struct window): Likewise.
12495 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12496 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12497 * buffer.c (init_buffer_once): Likewise.
12498 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12500 * process.c (Fformat_network_address): Use local var for size,
12503 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12505 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12506 * data.c (atof): Remove decl; no longer used or needed.
12507 (digit_to_number): Move to lread.c.
12508 (Fstring_to_number): Use new string_to_number function, to be
12509 consistent with how the Lisp reader treats infinities and NaNs.
12510 Do not assume that floating-point numbers represent EMACS_INT
12511 without losing information; this is not true on most 64-bit hosts.
12512 Avoid double-rounding errors, by insisting on integers when
12513 parsing non-base-10 numbers, as the documentation specifies.
12514 * lisp.h (string_to_number): New decl, replacing ...
12515 (isfloat_string): Remove.
12516 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12517 (read1): Do not accept +. and -. as integers; this
12518 appears to have been a coding error. Similarly, do not accept
12519 strings like +-1e0 as floating point numbers. Do not report
12520 overflow for integer overflows unless the base is not 10 which
12521 means we have no simple and reliable way to continue.
12522 Break out the floating-point parsing into a new
12523 function string_to_number, so that Fstring_to_number parses
12524 floating point numbers consistently with the Lisp reader.
12525 (digit_to_number): Move here from data.c. Make it static inline.
12526 (E_CHAR, EXP_INT): Remove, replacing with ...
12527 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12528 (string_to_number): New function, replacing isfloat_string.
12529 This function checks for valid syntax and produces the resulting
12530 Lisp float number too. Rework it so that string-to-number
12531 no longer mishandles examples like "1.0e+". Use strtoumax,
12532 so that overflow for non-base-10 numbers is reported only when
12533 there's no portable and simple way to convert to floating point.
12535 * textprop.c (set_text_properties_1): Rewrite for clarity,
12536 and to avoid GCC warning about integer overflow.
12538 * intervals.h (struct interval): Use EMACS_INT for members
12539 where EMACS_UINT might cause problems. See
12540 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12541 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12542 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12544 (offset_intervals): Tell GCC not to worry about length overflow
12545 when negating a negative length.
12547 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12548 (overrun_check_free): Likewise.
12550 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12551 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12554 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12555 (gnutls_make_error): Rename local to avoid shadowing.
12556 (gnutls_emacs_global_deinit): ifdef out; not used.
12557 (Fgnutls_boot): Use const for pointer to readonly storage.
12558 Comment out unused local. Fix pointer signedness problems.
12560 * lread.c (openp): Don't stuff size_t into an 'int'.
12561 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12562 about possible signed overflow.
12564 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12565 (GDK_KEY_g): Don't define if already defined.
12566 (xg_prepare_tooltip): Avoid pointer signedness problem.
12567 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12569 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12570 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12572 * xfns.c (Fx_window_property): Simplify a bit,
12573 to make a bit faster and to avoid GCC 4.6.0 warning.
12574 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12576 * fns.c (internal_equal): Don't assume size_t fits in int.
12578 * alloc.c (compact_small_strings): Tighten assertion a little.
12580 Replace pEd with more-general pI, and fix some printf arg casts.
12581 * lisp.h (pI): New macro, generalizing old pEd macro to other
12582 conversion specifiers. For example, use "...%"pI"d..." rather
12583 than "...%"pEd"...".
12584 (pEd): Remove. All uses replaced with similar uses of pI.
12585 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12586 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12587 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12588 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12589 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12590 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12591 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12593 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12594 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12595 * print.c (safe_debug_print, print_object): Likewise.
12596 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12598 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12599 avoiding the 0 flag, which is not portable.
12600 * process.c (Fmake_network_process): Use pI to avoid cast.
12601 * region-cache.c (pp_cache): Likewise.
12602 * xdisp.c (decode_mode_spec): Likewise.
12603 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12604 behavior on 64-bit hosts with printf arg.
12605 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12606 (x_stop_queuing_selection_requests): Likewise.
12607 (x_get_window_property): Don't truncate byte count to an 'int'
12610 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12611 here, since it parses constructs like leading '-' and spaces,
12612 which are not wanted; and it overflows with large numbers.
12613 Instead, simply match F[0-9]+, which is what is wanted anyway.
12615 * alloc.c: Remove unportable assumptions about struct layout.
12616 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12617 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12618 (allocate_vectorlike, make_pure_vector): Use the new macros,
12619 plus offsetof, to remove unportable assumptions about struct layout.
12620 These assumptions hold on all porting targets that I know of, but

12622 makes further changes easier.
12624 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".

13514 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13516 Fix more problems found by GCC 4.6.0's static checks.
13518 * xdisp.c (vmessage): Use a better test for character truncation.
13520 * charset.c (load_charset_map): <, not <=, for optimization,
13521 and to avoid potential problems with integer overflow.
13522 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13523 * casetab.c (set_identity, shuffle): Likewise.
13524 * editfns.c (Fformat): Likewise.
13525 * syntax.c (skip_chars): Likewise.
13527 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13528 This also lets GCC 4.6.0 generate slightly better loop code.
13530 * callint.c (Fcall_interactively): <, not <=, for optimization.
13531 (Fcall_interactively): Count the number of arguments produced,
13532 not the number of arguments given. This is simpler and lets GCC
13533 4.6.0 generate slightly better code.
13535 * ftfont.c: Distingish more carefully between FcChar8 and char.
13536 The previous code passed unsigned char * to a functions like
13537 strlen and xstrcasecmp that expect char *, which does not
13538 conform to the C standard.
13539 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13540 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13541 char * when the C standard requires it.
13543 * keyboard.c (read_char): Remove unused var.
13545 * eval.c: Port to Windows vsnprintf (Bug#8435).
13546 Include <limits.h>.
13547 (SIZE_MAX): Define if the headers do not.
13548 (verror): Do not give up if vsnprintf returns a negative count.
13549 Instead, grow the buffer. This ports to Windows vsnprintf, which
13550 does not conform to C99. Problem reported by Eli Zaretskii.
13551 Also, simplify the allocation scheme, by avoiding the need for
13552 calling realloc, and removing the ALLOCATED variable.
13554 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13556 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13557 But keep the doprint source code for now, as we might revamp it
13558 and use it again (Bug#8435).
13559 * lisp.h (doprnt): Remove.
13560 * Makefile.in (base_obj): Remove doprnt.o.
13561 * deps.mk (doprnt.o): Remove.
13563 error: Print 32- and 64-bit integers portably (Bug#8435).
13564 Without this change, on typical 64-bit hosts error ("...%d...", N)
13565 was used to print both 32- and 64-bit integers N, which relied on
13566 undefined behavior.
13567 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13568 * lisp.h (error, verror): Mark as printf-like functions.
13569 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13570 Report overflow in size calculations when allocating printf buffer.
13571 Do not truncate output string at its first null byte.
13572 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13573 Truncate the output at a character boundary, since vsnprintf does not
13575 * charset.c (check_iso_charset_parameter): Convert internal
13576 character to string before calling 'error', since %c now has the
13578 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13579 overflow when computing char to be passed to 'error'. Do not
13580 pass Lisp_Object to 'error'; pass the integer instead.
13581 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13582 formatted with plain %d.
13584 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13586 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13588 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13590 * xterm.c (x_catch_errors): Remove duplicate declaration.
13592 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13594 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13596 2011-04-10 Jim Meyering <meyering@redhat.com>
13598 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13599 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13600 return ssize_t not "int", and use size_t as the buffer length.
13601 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13602 * gnutls.h: Update declarations.
13603 * process.c (read_process_output): Use ssize_t, to match.
13604 (send_process): Likewise.
13606 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13608 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13610 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13612 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13613 Use unsigned char, to match FcChar8 type definition.
13615 * xterm.c (handle_one_xevent):
13616 * xmenu.c (create_and_show_popup_menu):
13617 * xselect.c (x_decline_selection_request)
13618 (x_reply_selection_request): Avoid type-punned deref of X events.
13620 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13622 Fix some uses of `int' instead of EMACS_INT.
13623 * search.c (string_match_1, fast_string_match)
13624 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13625 (scan_buffer, find_next_newline_no_quit)
13626 (find_before_next_newline, search_command, Freplace_match)
13627 (Fmatch_data): Make some `int' variables be EMACS_INT.
13629 * xdisp.c (display_count_lines): 3rd argument and return value now
13630 EMACS_INT. All callers changed.
13631 (pint2hrstr): Last argument is now EMACS_INT.
13633 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13634 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13635 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13636 (decode_coding_utf_16, decode_coding_emacs_mule)
13637 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13638 (decode_coding_ccl, decode_coding_charset)
13639 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13640 (decode_coding_iso_2022, decode_coding_emacs_mule)
13641 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13642 <char_offset, last_offset>: Declare EMACS_INT.
13643 (encode_coding_utf_8, encode_coding_utf_16)
13644 (encode_coding_emacs_mule, encode_invocation_designation)
13645 (encode_designation_at_bol, encode_coding_iso_2022)
13646 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13647 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13649 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13650 (encode_invocation_designation): Last argument P_NCHARS is now
13652 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13653 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13655 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13658 * ccl.c (Fccl_execute_on_string): Declare some variables
13661 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13663 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13665 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13667 * process.c (Fformat_network_address): Doc fix.
13669 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13671 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13673 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13675 * keyboard.c (read_char): Call Lisp function help-form-show,
13676 instead of using internal_with_output_to_temp_buffer.
13677 (Qhelp_form_show): New var.
13678 (syms_of_keyboard): Use DEFSYM macro.
13680 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13682 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13684 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13686 * process.c (Flist_processes): Remove to Lisp.
13687 (list_processes_1): Delete.
13689 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13691 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13693 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13695 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13697 Fix more problems found by GCC 4.6.0's static checks.
13699 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13701 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13703 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13705 * xdisp.c (vmessage): Mark as a printf-like function.
13707 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13709 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13711 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13712 printf-like functions.
13713 (tiff_load): Add casts to remove these marks before passing them
13714 to system-supplied API.
13716 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13718 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13719 This avoids several warnings with gcc -Wstrict-overflow.
13720 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13721 directly, rather than having caller test rule sign. This avoids
13722 some unnecessary tests.
13723 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13724 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13725 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13727 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13728 (xfont_open): Avoid unnecessary tests.
13730 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13732 * composite.h, composite.c (composition_gstring_put_cache):
13733 Use EMACS_INT, not int, for length.
13735 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13736 breaking out part of COMPOSITION_DECODE_RULE.
13737 (COMPOSITION_DECODE_RULE): Use it.
13738 * composite.c (get_composition_id): Remove unused local vars,
13739 by using the new macro.
13741 * textprop.c (set_text_properties_1): Change while to do-while,
13742 since the condition is always true at first.
13744 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13745 (interval_deletion_adjustment): Return unsigned value.
13748 * process.c (list_processes_1, create_pty, read_process_output):
13749 (exec_sentinel): Remove vars that were set but not used.
13750 (create_pty): Remove unnecessary "volatile"s.
13751 (Fnetwork_interface_info): Avoid possibility of int overflow.

13758 (update_syntax_table): Use unsigned instead of int.
13760 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13761 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13762 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13764 * print.c (print_error_message): Avoid int overflow.
13766 * font.c (font_list_entities): Redo for clarity,
13767 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13769 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13770 (font_score): Avoid potential overflow in diff calculation.
13772 * fns.c (substring_both): Remove var that is set but not used.
13773 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13775 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13777 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13778 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13779 can always succeed if overflow has undefined behavior.
13781 * search.c (boyer_moore, wordify): Remove vars set but not used.
13782 (wordify): Omit three unnecessary tests.
13784 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13785 All callers changed. This avoids the need for an unused var.
13787 * casefiddle.c (casify_region): Remove var that is set but not used.
13789 * dired.c (file_name_completion): Remove var that is set but not used.
13791 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13793 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13794 (Finsert_file_contents): Remove unnecessary code checking fd.
13796 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13797 Check for integer overflow on size calculations.
13799 * buffer.c (Fprevious_overlay_change): Remove var that is set
13802 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13803 Remove vars that are set but not used.
13804 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13805 (timer_check_2): Mark vars as initialized.
13807 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13809 * image.c (lookup_image): Remove var that is set but not used.
13810 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13812 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13813 that are set but not used.
13815 * xfns.c (make_invisible_cursor): Don't return garbage
13816 if XCreateBitmapFromData fails (Bug#8410).
13818 * xselect.c (x_get_local_selection, x_handle_property_notify):
13819 Remove vars that are set but not used.
13821 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13822 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13824 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13825 Remove var that is set but not used.
13826 (scroll_bar_windows_size): Now size_t, not int.
13827 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13828 Check for overflow.
13830 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13831 (map_tty_color) [!defined MSDOS]: Likewise.
13833 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13835 * coding.c: Remove vars that are set but not used.
13836 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13837 All callers changed.
13838 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13839 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13840 (decode_coding_charset): Remove vars that are set but not used.
13842 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13843 that is set but not used.
13845 * print.c (print_object): Remove var that is set but not used.
13847 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13848 The gnulib version avoids calling malloc in the usual case,
13849 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13850 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13851 * filelock.c (current_lock_owner): Likewise.
13852 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13853 * sysdep.c: Include allocator.h, careadlinkat.h.
13854 (emacs_no_realloc_allocator): New static constant.
13855 (emacs_readlink): New function.
13856 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13857 ../lib/careadlinkat.h.
13859 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13861 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13862 first non-nil return value).
13864 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13866 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13867 if not defined (Bug#8403).
13869 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13871 * xdisp.c (display_count_lines): Remove parameter `start',
13872 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13873 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13874 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13875 (fill_stretch_glyph_string): Remove parameters `row' and `area',
13876 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13877 and thereabouts. All callers changed.
13878 (get_per_char_metric): Remove parameter `f', unused since
13879 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13881 2011-04-02 Jim Meyering <meyering@redhat.com>
13883 do not dereference NULL upon failed strdup
13884 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13885 (ns_get_family): Likewise.
13887 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13889 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13891 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13893 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13896 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13898 Add lexical binding.
13900 * window.c (Ftemp_output_buffer_show): New fun.
13901 (Fsave_window_excursion):
13902 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13904 * lread.c (lisp_file_lexically_bound_p): New function.
13905 (Fload): Bind Qlexical_binding.
13906 (readevalloop): Remove `evalfun' arg.
13907 Bind Qinternal_interpreter_environment.
13908 (Feval_buffer): Bind Qlexical_binding.
13909 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13911 (syms_of_lread): Declare `lexical-binding'.
13913 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13915 * keyboard.c (eval_dyn): New fun.
13916 (menu_item_eval_property): Use it.
13918 * image.c (parse_image_spec): Use Ffunctionp.
13920 * fns.c (concat, mapcar1): Accept byte-code-functions.
13922 * eval.c (Fsetq): Handle lexical vars.
13923 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13924 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13925 (FletX, Flet): Obey lexical binding.
13926 (Fcommandp): Handle closures.
13927 (Feval): New `lexical' arg.
13928 (eval_sub): New function extracted from Feval. Use it almost
13929 everywhere where Feval was used. Look up vars in lexical env.
13931 (Ffunctionp): Move from subr.el.
13932 (Ffuncall): Handle closures.
13933 (apply_lambda): Remove `eval_flags'.
13934 (funcall_lambda): Handle closures and new byte-code-functions.
13935 (Fspecial_variable_p): New function.
13936 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13937 but without exporting it to Lisp.
13939 * doc.c (Fdocumentation, store_function_docstring):
13940 * data.c (Finteractive_form): Handle closures.
13942 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13945 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13947 (exec_byte_code): New function extracted from Fbyte_code to handle new
13948 calling convention for byte-code-functions. Add new byte-codes.
13950 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13952 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13954 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13956 * xdisp.c (redisplay_internal): Fix prototype.
13958 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13960 * xdisp.c (SCROLL_LIMIT): New macro.
13961 (try_scrolling): Use it when setting scroll_limit.
13962 Limit scrolling to 100 screen lines.
13963 (redisplay_window): Even when falling back on "recentering",
13964 position point in the window according to scroll-conservatively,
13965 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13967 (try_scrolling): When point is above the window, allow searching
13968 as far as scroll_max, or one screenful, to compute vertical
13969 distance from PT to the scroll margin position. This prevents
13970 try_scrolling from unnecessarily failing when
13971 scroll-conservatively is set to a value slightly larger than the
13972 window height. Clean up the case of PT below the margin at bottom
13973 of window: scroll_max can no longer be INT_MAX. When aggressive
13974 scrolling is in use, don't let point enter the opposite scroll
13975 margin as result of the scroll.
13976 (syms_of_xdisp) <scroll-conservatively>: Document the
13977 threshold of 100 lines for never-recentering scrolling.
13979 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13981 * dispextern.h (move_it_by_lines):
13982 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13983 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13984 (message_log_check_duplicate): Remove parameters `prev_bol' and
13985 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13986 (redisplay_internal): Remove parameter `preserve_echo_area',
13987 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13989 * indent.c (Fvertical_motion):
13990 * window.c (window_scroll_pixel_based, Frecenter):
13991 Don't pass `need_y_p' to `move_it_by_lines'.
13993 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13995 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13996 steal a few bits to be more compact.
13997 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13998 Remove unneeded casts.
14000 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14002 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14004 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14005 binding" message (bug#7967).
14007 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14009 Fix more problems found by GCC 4.6.0's static checks.
14011 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14012 Remove unused local var.
14014 * editfns.c (Fmessage_box): Remove unused local var.
14016 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14017 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14018 Omit unused local vars.
14019 * window.c (shrink_windows): Omit unused local var.
14020 * menu.c (digest_single_submenu): Omit unused local var.
14021 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14022 Omit unused local var.
14024 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14025 Don't assume string length fits in int.
14026 (keyremap_step, read_key_sequence): Use size_t for sizes.
14027 (read_key_sequence): Don't check last_real_key_start redundantly.
14029 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14030 instead of alloca (Bug#8344).
14032 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14033 (Fbacktrace_frame): Don't assume nframes fits in int.
14035 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14037 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14040 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14042 * cm.c (calccost): Turn while-do into do-while, for clarity.
14044 * keyboard.c (syms_of_keyboard): Use the same style as later
14045 in this function when indexing through an array. This also
14046 works around GCC bug 48267.
14048 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14050 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

14053 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14055 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14056 This avoids undefined behavior on integer overflow, and is a bit
14057 more convenient anyway since it is compared to a size_t variable.
14059 Variadic C functions now count arguments with size_t, not int.
14060 This avoids an unnecessary limitation on 64-bit machines, which
14061 caused (substring ...) to crash on large vectors (Bug#8344).
14062 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14063 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

14069 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14070 (funcall_lambda, mark_backtrace): Likewise.
14071 * fns.c (concat): Likewise.
14072 * frame.c (x_set_frame_parameters): Likewise.
14073 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14074 0 if not found, not -1. All callers changed.
14076 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14077 (stack_copy_size): Now size_t, not int.
14078 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

14082 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14083 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

14086 * lisp.h (multibyte_char_to_unibyte):
14087 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14088 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14089 * character.h (CHAR_TO_BYTE8):
14090 * cmds.c (internal_self_insert):
14091 * editfns.c (general_insert_function):
14092 * keymap.c (push_key_description):
14093 * search.c (Freplace_match):
14094 * xdisp.c (message_dolog, set_message_1): All callers changed.
14096 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14098 * keyboard.c (safe_run_hook_funcall): New function.
14099 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14100 don't set the hook to nil, but remove the offending function instead.
14101 (Qcommand_hook_internal): Remove, unused.
14102 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14103 Vcommand_hook_internal.
14105 * eval.c (enum run_hooks_condition): Remove.
14106 (funcall_nil, funcall_not): New functions.
14107 (run_hook_with_args): Call each function through a `funcall' argument.
14108 Remove `cond' argument, now redundant.
14109 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14110 (Frun_hook_with_args_until_failure): Adjust accordingly.
14111 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14113 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14115 * dispextern.h (string_buffer_position): Remove declaration.
14117 * print.c (strout): Remove parameter `multibyte', unused since
14118 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14120 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14121 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14122 All callers changed.
14124 * w32.c (_wsa_errlist): Use braces for struct initializers.
14126 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14127 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14128 All callers changed.

14134 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14135 All callers changed.
14137 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14139 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14150 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14152 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

14168 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14170 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14172 * w32.c (read_unc_volume): Use parameter `henum', instead of
14173 global variable `wget_enum_handle'.
14175 * keymap.c (describe_vector): Remove parameters `indices' and
14176 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14191 * gtkutil.c (xg_maybe_add_timer):
14192 * keyboard.c (readable_events):
14193 * process.c (wait_reading_process_output):
14194 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14196 * insdel.c (adjust_markers_gap_motion):
14197 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

14271 2011-03-23 Julien Danjou <julien@danjou.info>
14273 * term.c (Fsuspend_tty, Fresume_tty):
14274 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14275 * window.c (temp_output_buffer_show):

14282 * callint.c (Fcall_interactively):
14283 * buffer.c (Fkill_all_local_variables):
14284 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14286 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14287 unconditionally since it does the check itself.
14289 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14291 Fix more problems found by GCC 4.5.2's static checks.
14293 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14294 the first time through the loop, since we know p0 < p1 then.
14295 This also avoids a gcc -Wstrict-overflow warning.
14297 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14298 leading to a memory leak, possible in functions like
14299 load_charset_map_from_file that can allocate an unbounded number
14300 of objects (Bug#8318).
14302 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14303 that could (at least in theory) be that large.
14305 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14306 This is less likely to overflow, and avoids undefined behavior if
14307 overflow does occur. All callers changed. Use strtoul to scan
14308 for the unsigned long integer.
14309 (pint2hrstr): Simplify and tune code slightly.
14310 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14325 * process.c (Fmake_network_process): Use socklen_t, not int,
14326 where POSIX says socklen_t is required in portable programs.
14327 This fixes a porting bug on hosts like 64-bit HP-UX, where
14328 socklen_t is wider than int (Bug#8277).
14329 (Fmake_network_process, server_accept_connection):
14330 (wait_reading_process_output, read_process_output):
14333 * process.c: Rename or move locals to avoid shadowing.

14340 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14341 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14343 Make tparam.h and terminfo.c consistent.
14344 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14345 Include tparam.h instead, since it declares them.
14346 * cm.h (PC): Remove extern decl; tparam.h now does this.
14347 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14348 * terminfo.c: Include tparam.h, to check interfaces.
14349 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14350 (tparam): Adjust signature to match interface in tparam.h;
14351 this removes some undefined behavior. Check that outstring and len
14352 are zero, which they always are with Emacs.
14353 * tparam.h (PC, BC, UP): New extern decls.
14355 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14356 (xftfont_open): Rename locals to avoid shadowing.
14358 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14359 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14360 (OTF_TAG_SYM): Omit macro if not needed.
14361 (ftfont_list): Remove unused local.
14362 (get_adstyle_property, ftfont_pattern_entity):
14363 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14364 Rename locals to avoid shadowing.
14366 * xfont.c (xfont_list_family): Mark var as initialized.
14368 * xml.c (make_dom): Now static.
14370 * composite.c (composition_compute_stop_pos): Rename local to
14372 (composition_reseat_it): Remove unused locals.
14373 (find_automatic_composition, composition_adjust_point): Likewise.
14374 (composition_update_it): Mark var as initialized.
14375 (find_automatic_composition): Mark vars as initialized,
14376 with a FIXME (Bug#8290).
14378 character.h: Rename locals to avoid shadowing.
14379 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14380 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14381 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14382 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14383 to avoid shadowing.
14385 * textprop.c (property_change_between_p): Remove; unused.
14387 * intervals.c (interval_start_pos): Now static.
14389 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
14391 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
14392 Rename locals to avoid shadowing.
14394 * sound.c (wav_play, au_play, Fplay_sound_internal):
14395 Fix pointer signedness.
14396 (alsa_choose_format): Remove unused local var.
14397 (wav_play): Initialize a variable to 0, to prevent undefined
14398 behavior (Bug#8278).
14400 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14402 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14404 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14405 clobbering (Bug#8298).
14406 * sysdep.c (sys_subshell): Likewise.
14407 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14409 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14410 This should get cleaned up, so that child_setup has the
14411 same signature on all platforms.
14413 * callproc.c (call_process_cleanup): Now static.
14414 (relocate_fd): Rename locals to avoid shadowing.
14416 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

14545 some of which prompt warnings from gcc -Wbad-function-cast.
14546 (Fformat_time_string, Fencode_time, Finsert_char):

14575 (Fmemory_limit): Cast sbrk's returned value to char *.
14577 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14583 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14584 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14585 to use the following functions instead of these macros.
14586 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14587 EMACS_INT, since callers assume the returned value fits in int.
14588 (upcase1): Likewise, for UPCASE_TABLE.
14589 (uppercasep, lowercasep, upcase): New static inline functions.
14590 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14600 (regex_compile, re_match_2_internal): Mark locals as initialized.
14601 (RETALLOC_IF): Define only if needed.
14602 (WORDCHAR_P): Likewise. This one is never needed, but is used
14603 only in a comment talking about a compiler bug, so put inside
14604 the #if 0 of that comment.
14605 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14606 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14632 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14633 New macros, so that the caller can use some names other than
14634 gcpro1, gcpro2, etc.
14635 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14637 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14638 argument, for consistency with GCPRO2_VAR, etc: it is now the
14639 prefix of the variable, not the variable itself. All uses
14641 * dired.c (directory_files_internal, file_name_completion):
14642 Rename locals to avoid shadowing.
14644 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14645 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14646 dired.c's scmp function, had undefined behavior.
14647 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14648 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14649 * buffer.h: ... to here, because these macros use current_buffer,
14650 and the new implementation with inline functions needs to have
14651 current_buffer in scope now, rather than later when the macros
14653 (downcase, upcase1): New static inline functions.
14654 (DOWNCASE, UPCASE1): Reimplement using these functions.
14655 This avoids undefined behavior in expressions like
14656 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14657 from race conditions in accessing the global variables
14658 case_temp1 and case_temp2.
14659 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14660 * lisp.h (case_temp1, case_temp2): Remove their decls.
14661 * character.h (ASCII_CHAR_P): Move from here ...
14662 * lisp.h: ... to here, so that the inline functions mentioned
14663 above can use them.
14665 * dired.c (directory_files_internal_unwind): Now static.
14667 * fileio.c (file_name_as_directory, directory_file_name):

14670 (file_name_as_directory): Use const pointers when appropriate.
14671 (Fexpand_file_name): Likewise. In particular, newdir might
14672 point at constant storage, so make it a const pointer.
14673 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14674 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14676 (Fset_file_times, Finsert_file_contents, auto_save_error):

14681 to avoid shadowing.
14683 * marker.c (bytepos_to_charpos): Remove; unused.
14685 * lisp.h (verify_bytepos, count_markers): New decls,
14686 so that gcc does not warn that these functions aren't declared.
14688 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14689 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14690 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14691 (copy_text): Remove unused local var.
14693 * filelock.c (within_one_second): Now static.
14694 (lock_file_1): Rename local to avoid shadowing.
14696 * buffer.c (fix_overlays_before): Mark locals as initialized.
14697 (fix_start_end_in_overlays): Likewise. This function should be
14698 simplified by using pointers-to-pointers, but that's a different
14700 (switch_to_buffer_1): Now static.
14701 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14702 (report_overlay_modification): Rename locals to avoid shadowing.
14704 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14705 Fix pointer signedness issue.
14706 (sys_subshell): Mark local as volatile if checking for lint,
14707 to suppress a gcc -Wclobbered warning that does not seem to be right.
14708 (MAXPATHLEN): Define only if needed.
14710 * process.c (serial_open, serial_configure): Move decls from here ...
14711 * systty.h: ... to here, so that they can be checked.
14713 * fns.c (get_random, seed_random): Move extern decls from here ...
14714 * lisp.h: ... to here, so that they can be checked.
14716 * sysdep.c (reset_io): Now static.
14717 (wait_for_termination_signal): Remove; unused.
14719 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

14722 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14723 (DENSE_TABLE_SIZE): Remove; unused.
14724 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14725 (describe_map_tree):
14726 Rename locals to avoid shadowing.
14728 * keyboard.c: Declare functions static if they are not used elsewhere.
