226 * w32.c (init_environment): Change the default values of many
227 environment variables in dflt_envvars[] to NULL, to avoid pushing
228 them into environment when they were not already defined. Remove
229 the code that deletes site-lisp subdirectories from the default
230 value of EMACSLOADPATH, as it is no longer needed.
231 (check_windows_init_file): Now external, not static. Use
232 Vload_path as is, without adding anything, as this function is now
233 called when Vload_path is already set up.
235 * w32.h (check_windows_init_file): Add prototype.
237 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

242 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
243 any, in the DEFALT argument into the root of the Emacs build or
244 installation tree, as appropriate.
246 * callproc.c (init_callproc_1): Call decode_env_path instead of
247 doing its equivalent by hand.
248 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
249 the code that sets Vexec_path run on MS-Windows.
251 * lread.c (init_lread): Add comments to #ifdef's.
253 * msdos.c (dos_set_window_size, IT_update_begin)
254 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

261 Now constants, not macros.
263 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
265 Remove unnecessary casts involving pointers.
266 These casts are no longer needed now that we assume C89 or later,

268 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
269 (make_pure_float, make_pure_vector):
270 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

280 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
281 Remove unnecessary pointer casts.
282 * alloc.c (record_xmalloc): New function.
283 * lisp.h (record_xmalloc): New decl.
284 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
285 more like a function. This is because the pointer cast is not
286 needed. All uses changed.
287 * print.c (print_string, print_error_message): Avoid length recalc.
289 Improve fix for macroexp crash with debugging (Bug#12118).
290 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
291 ARRAY_MARK_FLAG when checking subscripts, because ASET is
292 not supposed to be invoked from the garbage collector.
293 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
294 (gc_aset): New function, which is like ASET but can be
295 used in the garbage collector.
296 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

309 (map_w32_filename): Improve commentary. Simplify switch.
310 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
311 headers (most versions of MinGW w32api don't).
312 (get_security_info, create_symbolic_link)
313 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
315 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
316 in the argument file name.

318 GetFileAttributes fails with network-related error codes.
319 (sys_rename): Diagnose renaming of a symlink when the user doesn't
320 have the required privileges.
321 (get_file_security_desc_by_name): Renamed from
322 get_file_security_desc.
323 (stat_worker): New function, with most of the guts of 'stat', and
324 with addition of handling of symlinks and support for 'lstat'. If
325 possible, get file's attributes and security information by
326 handle, not by name. Produce S_IFLNK bit for symlinks, when
328 (stat, lstat): New functions, call 'stat_worker'.
329 (symlink, readlink, careadlinkat): Rewritten to create and resolve
330 symlinks when the underlying filesystem supports them.
332 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
334 Fix macroexp crash on Windows with debugging (Bug#12118).
335 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
336 checking subscripts; problem introduced with the recent
337 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
338 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
339 since it's used in non-static inline functions now.
341 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
342 Don't assume buffer size fits in 'int'. Remove unused local.
344 Use C99-style 'extern inline' if available.
345 * buffer.h (BUFFER_INLINE):
346 * category.h (CATEGORY_INLINE):

363 * dispnew.c (DISPEXTERN_INLINE):
364 * sysdep.c (SYSTIME_INLINE):
365 Define to EXTERN_INLINE, so that the corresponding functions
366 are compiled into code.
367 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
368 (INLINE_HEADER_END): New macros.
369 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

391 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
393 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
394 This how ASET and AREF are supposed to work, and makes
395 it easier to think about future improvements. See
396 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
397 * charset.h (set_charset_attr): New function.

887 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from

889 the fix for 12036 would have avoided some of the problems noted in
890 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
891 would have been more obvious.

902 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
903 not be usable in #if. This simplifies things.
905 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
907 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
909 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

914 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
915 Adjust to changes in lisp.h and emacs.c, by using
916 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead

918 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
919 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
920 instead of gdb_valbits.

959 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
960 than macros. This simplifies debugging in the usual case, since

1826 Prefer snprintf to strncpy.
1827 * nsterm.m (ns_term_init):
1828 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1829 * nsterm.m (ns_term_init):
1830 Avoid the need for strncpy, by using build_string or
1831 make_unibyte_string directly. Use dtoastr, not snprintf.
1832 * process.c (Fmake_network_process): Diagnose service names that
1833 are too long, rather than silently truncating them or creating
1834 non-null-terminated names.
1835 (Fnetwork_interface_info): Likewise, for interface names.
1836 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1837 Prefer sprintf to strncat.
1838 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

1864 Optimize pure C strings initialization.
1865 * lisp.h (make_pure_string): Fix prototype.
1866 (build_pure_c_string): New function, defined as static inline. This
1867 provides a better opportunity to optimize away calls to strlen when
1868 the function is called with compile-time constant argument.
1869 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1870 argument, adjust users accordingly. Use build_pure_c_string where
1872 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1873 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1874 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1876 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1878 Avoid calls to strlen in miscellaneous functions.
1879 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1880 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1881 * lread.c (openp): Likewise.
1883 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1885 Avoid calls to strlen in path processing functions.
1886 * fileio.c (file_name_as_directory): Add comment. Change to add
1887 srclen argument and return the length of result. Adjust users
1889 (directory_file_name): Fix comment. Change to add srclen argument,

1892 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1894 2012-07-10 Glenn Morris <rgm@gnu.org>
1896 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

1901 * s/gnu.h (DATA_START): Move definitions to configure.
1903 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1904 We include usg5-4-common.h, which defines them both.
1906 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1907 O_RDONLY already includes it).
1909 Stop ns builds setting the EMACSLOADPATH environment variable.
1910 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1911 Now it does not set EMACSLOADPATH, just returns the load-path string.
1912 * nsterm.h: Update accordingly.
1913 * lread.c [HAVE_NS]: Include nsterm.h.
1914 (init_lread) [HAVE_NS]: Use ns_load_path.

1917 2012-07-09 Glenn Morris <rgm@gnu.org>
1919 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1920 since the included bsd-common.h does so.
1922 Stop ns builds setting the EMACSPATH environment variable.
1923 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1924 (ns_init_paths): Do not set EMACSPATH.
1925 * nsterm.h (ns_exec_path): Add it.
1926 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1929 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1931 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1933 * process.c (wait_reading_process_output): 'waitchannels' was unset
1934 when read_kbd || !NILP (wait_for_cell); fix this.
1936 Add GCC-style 'const' attribute to functions that can use it.
1937 * character.h (char_resolve_modifier_mask):
1938 * keyboard.h (make_ctrl_char):
1939 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1946 Declare the dummy function with ATTRIBUTE_CONST.
1947 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1948 Add decls with ATTRIBUTE_CONST.
1950 Minor improvements to make_formatted_string.
1951 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1952 where int is good enough, as vsprintf returns an int.
1953 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1955 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1957 Use make_formatted_string to avoid double length calculation.
1958 * lisp.h (make_formatted_string): New prototype.
1959 * alloc.c (make_formatted_string): New function.
1960 * buffer.c (Fgenerate_new_buffer_name): Use it.

1964 * frame.c (make_terminal_frame, set_term_frame_name)
1965 (x_report_frame_params): Likewise.
1966 * image.c (gs_load): Likewise.
1967 * minibuf.c (get_minibuffer): Likewise.

1982 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1984 Move marker debugging code under MARKER_DEBUG.
1985 * marker.c (MARKER_DEBUG): Move marker debugging code under
1986 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1987 for bootstrap with --enable-checking (~3x slowdown reported
1988 by Juanma Barranquero <lekktu@gmail.com>).
1989 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1991 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1993 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1994 See <http://bugs.gnu.org/11825#29>.
1996 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1998 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1999 has no font, use the frame's font. (Bug#11813)
2000 (display_line): Add commentary about displaying truncation glyphs
2002 (produce_special_glyphs): Move here from term.c.
2004 * term.c (produce_special_glyphs): Move to xdisp.c.
2006 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2009 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2011 * xdisp.c (display_line): Avoid warning about implicit declaration
2014 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2016 * lisp.h: Remove empty conditional.
2018 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2020 * lread.c (load_path_check): Now static.
2022 Fix some minor --with-ns problems found by static checking.
2023 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2024 (x_set_font) [!HAVE_X_WINDOWS]:
2025 * image.c (xpm_load_image) [HAVE_NS]:
2026 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2027 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2028 Remove unused local.
2029 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2030 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2031 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2032 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2033 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2034 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2035 Fix pointer signedness problem.
2036 * xfaces.c (FRAME_X_FONT_TABLE):
2037 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2039 2012-07-07 Glenn Morris <rgm@gnu.org>
2041 * lread.c (load_path_check): New function, split from init_lread.
2042 (init_lread): Reorganize. Motivation:
2043 If EMACSLOADPATH is set, check/warn about that rather than the
2044 defaults, which we are not going to use. Hence we can remove
2045 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2046 Don't warn if site-lisp directories are missing.
2047 If not installed, start from a blank load-path, since
2048 PATH_LOADSEARCH refers to the eventual installation directories.
2050 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2052 Support truncation and continuation glyphs on GUI frames, when
2053 fringes are disabled. (Bug#11832)
2054 * xdisp.c (init_iterator): Get dimensions of truncation and
2055 continuation glyphs even if on GUI frames. Adjust
2056 it->last_visible_x on GUI frames when the left or right fringes,
2057 or both, are absent.
2058 (start_display, move_it_in_display_line_to): Handle the case of a
2059 GUI frame without a fringe to display continuation or truncation
2061 (insert_left_trunc_glyphs): Support GUI frames: make sure
2062 truncation glyphs overwrite enough glyphs from the current line to
2063 have sufficient space in pixels.
2064 (display_line): Support truncation and continuation glyphs on GUI
2065 frames. If some spare pixels are left on the line after inserting
2066 the truncation glyphs, fill that space with a stretch glyph of a
2067 suitably computed width.
2069 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2070 produce_glyphs, to support GUI sessions.
2072 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2074 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2076 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2078 Do not require float-time's arg to fit in time_t (Bug#11825).
2079 This works better on hosts where time_t is unsigned, and where
2080 float-time is applied to the (negative) difference between two times.
2081 * editfns.c (decode_time_components): Last arg is now double *,
2082 not int *, and means to store all the result as a double, without
2083 worrying about whether the seconds part fits in time_t.
2084 All callers changed.
2085 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2086 All callers changed.
2087 (Ffloat_time): Do not fail merely because the specified time falls
2088 outside of time_t range.
2090 2012-07-07 Glenn Morris <rgm@gnu.org>
2092 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2098 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2099 Update dependencies.
2101 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2103 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

2107 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2108 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2109 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2110 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2112 * xfont.c (compare_font_names): Redo to omit the need for casts.
2114 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2116 * xfns.c (Fx_change_window_property): Doc fix.
2117 * w32fns.c (Fx_change_window_property): Doc fix.
2119 * w32fns.c (Fx_window_property): Accept the same arguments as the
2120 X Windows version. Doc fix.
2121 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2123 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2124 Eli Zaretskii <eliz@gnu.org>
2126 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2127 Windows-specific code from nt/config.nt moved here.
2128 Obsolete settings removed.
2130 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2132 * process.c: Avoid unnecessary calls to gettime.
2133 (wait_reading_process_output): Don't get the time of day
2134 when gobbling data immediately and not waiting, as there's no need
2135 for it in that case. This removes a FIXME.
2137 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2139 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2140 is defined (Bug#11768).
2142 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2144 Fix marker debugging code.
2145 * marker.c (byte_char_debug_check): Do not perform the check
2146 if buffer is not multibyte.
2147 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2148 Call byte_char_debug_check with correct arguments.
2150 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2152 Compile marker debugging code only if ENABLE_CHECKING is defined.
2153 * marker.c (byte_char_debug_check, count_markers):
2154 Use only if ENABLE_CHECKING is defined.
2155 (byte_debug_flag): Remove.
2156 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2157 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2159 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2161 Avoid code repetition in marker-related functions.
2162 * marker.c (attach_marker): New function.
2163 (Fset_marker, set_marker_restricted, set_marker_both)
2164 (set_marker_restricted_both): Use it.
2165 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2166 Consistently rename charno to charpos.
2167 (marker_position): Add eassert.
2168 (marker_byte_position): Convert to eassert.

2187 * window.c (save_window_save): Likewise.
2189 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2191 Do not use Fdelete_overlay in delete_all_overlays
2192 to avoid redundant calls to unchain_overlay.
2193 * buffer.c (drop_overlay): New function.
2194 (delete_all_overlays, Fdelete_overlay): Use it.
2195 * minibuf.c (get_minibuffer): Fix comment.
2197 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2199 Port to OpenBSD 5.1 amd64.
2200 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2201 This is needed for OpenBSD, and should be harmless on all BSD systems.
2202 Also, include <sys/sysctl.h>, as it should be available on all
2203 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2204 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2205 use p_pid member, not kp_proc.pid.
2207 2012-07-06 Glenn Morris <rgm@gnu.org>
2209 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2211 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2213 More xmalloc and related cleanup.
2214 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2215 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2222 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2224 Omit needless casts involving void * pointers and allocation.
2225 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2226 as the former is more robust if P's type is changed.
2227 Prefer xzalloc to xmalloc + memset 0.
2228 Simplify malloc-or-realloc to realloc.
2229 Don't worry about xmalloc returning a null pointer.
2230 Prefer xstrdup to xmalloc + strcpy.
2231 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2233 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2234 alloca of a constant.
2236 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2238 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2239 hscroll is larger than the line width. Fixes long and futile
2240 looping inside extend_face_to_end_of_line (on a TTY) producing
2241 glyphs that are not needed and thrown away.
2243 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2245 * marker.c (set_marker_restricted_both): Simplify by using
2248 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2266 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2267 with default display (Bug#11768).
2269 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2271 * xdisp.c (window_hscroll_limited): New function.
2272 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2273 coordinates when window's hscroll is set to insanely large
2276 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2278 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2279 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2281 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2284 * lisp.h (xzalloc): New prototype. Omit needless casts.
2285 * alloc.c (xzalloc): New function. Omit needless casts.

2287 xmalloc with following memset to xzalloc.

2339 * fileio.c (time_error_value): Check the right error number.
2340 Problem reported by Troels Nielsen in
2341 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2343 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2345 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2346 This should be fixed in a better way; see Eli Zaretskii in
2347 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2348 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2350 * fileio.c (time_error_value): Rename from special_mtime.
2351 The old name's problems were noted by Eli Zaretskii in
2352 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2354 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2355 This variable's comment says Emacs needs at least one GDB-visible
2356 symbol of type enum pvec_type, to work around GDB problems.
2357 The symbol's value doesn't matter.
2359 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2360 that causes compilation to fail on pre-C99 compilers.
2362 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2364 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2365 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2367 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2369 * buffer.c (init_buffer_once): Fix initialization of
2370 headers for buffer_defaults and buffer_local_symbols.
2371 Reported by Juanma Barranquero <lekktu@gmail.com>.
2373 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2375 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2376 * lisp.h (enum pvec_type): Use fewer bits.
2377 (PSEUDOVECTOR_SIZE_BITS): New constant.
2378 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2379 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2380 change in pvec_type.
2381 (PSEUDOVECTOR_TYPEP): New macro.
2382 (TYPED_PSEUDOVECTORP): Use it.
2383 * fns.c (internal_equal): Adapt code to extract pvectype.
2384 * emacs.c (gdb_pvec_type): Update type.
2385 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2386 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2387 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2388 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2389 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2390 abusing vector->header.next.nbytes.
2391 (live_vector_p): Use PVEC_TYPE.
2392 (mark_object): Adapt code to extract pvectype. Use switch.
2394 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2396 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2397 Tighten new eassert a bit.
2399 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2401 Fix compilation with --enable-gcc-warnings and -O1
2403 * doprnt.c (doprnt): Change type of tem to int, initialize
2404 to avoid compiler warning. Add eassert.
2405 * search.c (simple_search): Initialize match_byte to avoid
2406 compiler warning. Add eassert.
2408 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2410 Avoid weird behavior with large horizontal scrolls.
2411 Without this change, for example, large hscroll values would
2412 mess up Emacs's display on Fedora 15 x86, presumably due to
2413 overflows in int calculations in the display code.
2414 Also, if buffers had long lines, Emacs would freeze.
2415 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2416 (set_window_hscroll): New function, containing the old guts of
2417 Fset_window_hscroll. Return the clipped value.
2418 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2419 This avoids the need to check against PTRDIFF_MAX.
2421 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2423 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2425 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2427 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2429 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2430 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2431 since GCC 4.4.6 issues a bogus warning for them.
2433 Fix bugs in file timestamp newness comparisons.
2434 * fileio.c (Ffile_newer_than_file_p):
2435 * lread.c (Fload): Use full timestamp resolution of files,
2436 not just the 1-second resolution, so that files that are only
2437 slightly newer still count as newer.
2438 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2439 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2441 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2443 * fileio.c: Improve handling of file time marker. (Bug#11852)
2444 (special_mtime): New function.
2445 (Finsert_file_contents, Fverify_visited_file_modtime):
2446 Use it to set special mtime values consistently.
2448 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2450 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2451 marker for non-existing file. (Bug#11852)
2453 2012-07-03 Glenn Morris <rgm@gnu.org>
2455 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2456 and did not make it into globals.h).
2458 2012-07-03 Tom Tromey <tromey@redhat.com>
2460 * window.c (Fset_window_margins, Fset_window_fringes)
2461 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2462 * textprop.c (Fprevious_property_change): No longer static.
2463 * syntax.c (Fsyntax_table_p): No longer static.

2484 * dispextern.h: Remove EXFUNs.
2485 * intervals.h: Remove EXFUNs.
2486 * fontset.h: Remove EXFUN.

2491 * w32term.h: Remove EXFUNs.
2492 * window.h: Remove EXFUNs.

2494 * xterm.h: Remove EXFUN.
2496 2012-07-03 Glenn Morris <rgm@gnu.org>
2498 * lisp.h (Frandom): Make it visible to C.
2499 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2500 buffer for invisible buffers. (Bug#1229)
2502 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2504 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2505 values which aren't power of 2.
2506 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2507 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2510 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2512 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2514 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2516 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2518 * alloc.c (allocate_vector_block): Remove redundant
2519 calls to mallopt if DOUG_LEA_MALLOC is defined.
2520 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2521 avoid calls to mallopt if zero_vector is returned.
2523 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2525 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2526 is enabled, avoid dereferencing NULL current_sblock if
2529 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2531 Cleanup basic buffer management.
2532 * buffer.h (struct buffer): Change layout to use generic vector
2533 marking code. Fix some comments. Change type of 'clip_changed'
2534 to bitfield. Remove unused #ifndef old.
2535 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2536 (GET_OVERLAYS_AT): Fix indentation.
2537 (for_each_per_buffer_object_at): New macro.

2541 * alloc.c (allocate_buffer): Adjust to match new layout of
2542 struct buffer. Fix comment.
2543 (mark_overlay): New function.

2546 (mark_object): Use it. Adjust marking of misc objects
2547 and related comments.
2549 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2551 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2552 wrapper that is not needed because the wrapped code is a no-op (zero
2553 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2554 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2556 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2558 * alloc.c (mark_buffer): Simplify. Remove prototype.
2559 (mark_object): Add comment. Reorganize marking of vector-like
2560 objects. Use CHECK_LIVE for all vector-like objects except buffers
2561 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2562 redundant calls to mark_vectorlike for bool vectors.
2564 2012-06-30 Glenn Morris <rgm@gnu.org>
2566 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2568 * epaths.in (PATH_SITELOADSEARCH): New.
2569 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2570 This is rather than relying on --enable-locallisppath elements
2571 having "site-lisp" in their names. (Bug#10208#25, 11658)
2573 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2575 * w32proc.c (sys_select): Accept and ignore one more argument.
2577 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2579 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2580 (pselect) [!MS_DOS]: Redirect to sys_select.
2582 * sysdep.c: Don't include dos.h and dosfns.h.
2584 * process.c (sys_select):
2585 * msdos.c (sys_select): Accept one more argument and ignore it.
2587 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2588 adapt data types and code to that.
2591 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2592 which clashes with the gnulib function of the same name.
2594 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2596 * font.c (font_style_to_value, font_style_symbolic)
2597 (font_prop_validate_style): Add type checks for values in
2600 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2602 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2605 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2607 * xdisp.c (try_window_id): Undo last change.
2609 * w32.c (getwd): Adjust commentary about startup_dir.
2610 (init_environment): Always call sys_access, even in non-MSVC
2611 builds. Don't chdir to the directory of the Emacs executable.
2612 This undoes code from 1997 which was justified by the need to
2613 "avoid conflicts when removing and renaming directories". But its
2614 downside was that every relative file name was being interpreted
2615 relative to the directory of the Emacs executable, which can never
2616 be TRT. In particular, it broke sys_access when called with
2617 relative file names.
2618 (sys_access): Map GetLastError to errno.
2620 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2622 * window.h (struct window): Change type of 'fringes_outside_margins'

2626 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2629 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2631 * gnutls.c (emacs_gnutls_handshake):
2632 Add QUIT to make the loop interruptible.
2634 2012-06-29 Glenn Morris <rgm@gnu.org>
2636 * charset.c (init_charset): Make lack of etc/charsets fatal.
2638 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2640 * editfns.c (region_limit): Fix type mismatch.
2642 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2644 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2645 undefined. Convert from xassert to eassert.
2646 * nsmenu.m: Convert from xassert to eassert.
2647 * nsterm.m: Likewise.
2649 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2651 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2653 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2655 Avoid integer overflow on scroll-left and scroll-right.
2656 * window.c (HSCROLL_MAX): New macro.
2657 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2658 overflow when requested scroll falls outside ptrdiff_t range.
2660 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2662 * window.h (struct window): Change type of 'hscroll',
2663 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2664 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2665 Adjust users accordingly.
2666 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2667 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2668 from EMACS_INT to ptrdiff_t.
2669 (make_window): Omit redundant initialization.
2671 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2673 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2675 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2677 * window.h (struct window): Change type of 'use_time' and
2678 'sequence_number' from Lisp_Object to int.

2687 enabled with --enable-checking=[all,glyphs] configure option.
2688 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2689 adjust comments accordingly.

2740 avoid GCC warning about unused macro.
2742 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2744 * alloc.c (allocate_string): Omit intervals initialization.
2745 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2746 as in make_pure_string and make_pure_c_string.
2748 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2750 * alloc.c (allocate_string): Fix last change.
2752 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2754 * alloc.c (allocate_string): Remove two redundant calls
2755 to memset, add explicit initialization where appropriate.

2802 * alloc.c: Remove build_string.
2803 * lisp.h: Define build_string as static inline. This provides
2804 a better opportunity to optimize away calls to strlen when the
2805 function is called with compile-time constant argument.
2806 * image.c (imagemagick_error): Convert to build_string.
2807 * w32proc.c (sys_spawnve): Likewise.
2808 * xterm.c (x_term_init): Likewise.
2810 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2812 Use sprintf return value instead of invoking strlen on result.
2813 In the old days this wasn't portable, since some sprintf
2814 implementations returned char *. But they died out years ago and
2815 Emacs already assumes sprintf returns int.
2816 Similarly for float_to_string.
2817 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2818 * ccl.c (ccl_driver):
2819 * character.c (string_escape_byte8):

2822 * print.c (print_object):
2823 * xdisp.c (message_dolog):
2824 * xfns.c (syms_of_xfns):
2825 Use sprintf or float_to_string result to avoid need to call strlen.
2826 * data.c (Fnumber_to_string):
2827 Use make_unibyte_string, since the string must be ASCII.
2828 * lisp.h, print.c (float_to_string): Now returns int length.
2829 * term.c (produce_glyphless_glyph):
2830 Use sprintf result rather than recomputing it.
2832 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2833 * Makefile.in (ALL_CFLAGS):
2834 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
2835 * gmalloc.c, regex.c: Include <config.h> unconditionally.
2837 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2839 * dispextern.h (xstrcasecmp): Define to library function
2840 strcasecmp if available.
2841 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
2843 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

2856 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
2858 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2859 sprintf already null-terminates its output.
2861 * xfns.c (x_window): Remove redundant cast.
2863 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2865 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2866 `const char *' to `char *' to avoid compiler warning.
2868 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2870 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2871 instead of truncating it to 63 (admittedly a generous limit).
2873 * process.c: Fix spelling and caps in comments.
2875 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2877 * emacs.c (setpgrp): Remove definition, unused.

2921 Use _Noreturn rather than NO_RETURN.
2922 No need for separate decl merely because of _Noreturn.
2923 * sound.c (sound_warning, parse_sound):
2924 Remove unnecessary forward decls.
2926 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2928 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
2929 * lisp.h (WAIT_READING_MAX): New macro.
2930 * dispnew.c (Fsleep_for, sit_for):
2931 * keyboard.c (kbd_buffer_get_event):
2932 * process.c (Faccept_process_output):
2933 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2934 This improves on the previous patch, which introduced a bug
2935 when time_t is unsigned and as wide as intmax_t.
2936 See <http://bugs.gnu.org/9000#51>.
2938 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2940 * dispnew.c (sit_for, Fsleep_for):
2941 * keyboard.c (kbd_buffer_get_event):

2954 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2955 Privately reported by Herbert J. Skuhra.
2956 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2958 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2959 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2961 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2963 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
2964 last argument of make_unibyte_string.
2966 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
2967 language ID in the event parameters.
2969 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2970 event.code, not the obscure "character set ID".
2972 2012-06-23 Chong Yidong <cyd@gnu.org>
2974 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
2976 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2978 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

2993 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2994 Privately reported by Herbert J. Skuhra.

2999 Don't assume EMACS_TIME and struct timeval are the same type.
3001 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3003 Support higher-resolution time stamps (Bug#9000).
3004 The time stamps are only nanosecond-resolution at the C level,
3005 since that's the best that any real-world system supports now.
3006 But they are picosecond-resolution at the Lisp level, as that's
3007 easy, and leaves room for future OS improvements.
3009 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3012 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3013 Don't get current time unless it's needed.
3015 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3016 now provides it if it's absent.
3017 (start_atimer): Port to higher-res time stamps.
3018 Check for time stamp overflow. Don't get current time more
3019 often than is needed.
3021 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3022 Include systime.h, not time.h.
3023 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3025 * dired.c: Include stat-time.h.
3026 (Ffile-attributes): File times now have higher resolution.
3028 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3029 (struct image): Timestamp now has higher resolution.
3031 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3032 has at least microseconds now. All uses removed.
3033 (update_frame, update_single_window, update_window, update_frame_1)
3034 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3036 * editfns.c (time_overflow): Now extern.
3037 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3038 (float-time, Fformat_time_string, Fcurrent_time_string)
3039 (Fcurrent_time_zone): Accept and generate higher-resolution
3041 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3042 (decode_time_components, lisp_seconds_argument): New functions.
3043 (make_time): Now static.
3044 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3045 Report an error if the time is invalid, rather than having the caller
3048 * fileio.c: Include <stat-time.h>
3049 (Fcopy_file): Copy higher-resolution time stamps.
3050 Prefer to set the time stamp via a file descriptor if that works.
3051 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3052 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3053 (Fvisited_file_modtime, Fset_visited_file_modtime):
3054 Support higher-resolution time stamps.
3056 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3058 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3060 * image.c (prepare_image_for_display, clear_image_cache)
3061 (lookup_image): Port to higer-resolution time stamps.
3063 * keyboard.c (start_polling, bind_polling_period):
3064 Check for time stamp overflow.
3065 (read_char, kbd_buffer_get_event, timer_start_idle)
3066 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3067 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3068 Port to higher-resolution time stamps. Do not assume time_t is signed.
3069 (decode_timer): New function. Timers are now vectors of length 9,
3070 not 8, to accommodate the picosecond component.
3071 (timer_check_2): Use it.
3073 * nsterm.m (select_timeout, timeval_subtract): Remove.
3074 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3075 as they're a bit more accurate and handle overflow better.
3076 (ns_select): Change prototype to be compatible with pselect.
3077 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3078 * nsterm.h (ns_select): Adjust prototype.
3080 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3081 us-resolution time stamps.
3082 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3084 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3086 * lisp.h (time_overflow): New decl.
3087 (wait_reading_process_output): First arg is now intmax_t, not int,
3088 to accommodate larger waits.
3090 * process.h (struct Lisp_Process.read_output_delay):
3091 Now counts nanoseconds, not microseconds.
3092 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3094 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3095 (wait_reading_process_output):
3096 Port to ns-resolution time stamps.
3097 (Faccept_process_output, wait_reading_process_output):
3098 Check for time stamp overflow. Do not assume time_t is signed.
3099 (select_wrapper): Remove; we now use pselect.
3100 (Fprocess_attributes): Now generates ns-resolution time stamps.
3102 * sysdep.c: Include utimens.h. Don't include utime.h
3103 or worry about struct utimbuf; gnulib does that for us now.
3104 (gettimeofday): Remove; gnulib provides a substitute.
3105 (make_timeval): New function.
3106 (set_file_times): Now sets ns-resolution time stamps.
3107 New arg FD; all uses changed.
3108 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3109 (system_process_attributes):
3110 Now returns ns-resolution time stamp. All uses changed.
3111 Check for time stamp overflow.
3113 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3114 provides a substitute now.
3116 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3117 since it guarantees struct timespec.
3118 (EMACS_TIME): Now struct timespec, so that we can support
3119 ns-resolution time stamps.
3120 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3121 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3122 (EMACS_USECS): Remove.
3123 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3124 so multiply the arg by 1000 before storing it.
3125 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3127 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3128 Port to ns-resolution time stamps.
3129 (EMACS_TIME_NEG_P): Remove; replaced by....
3130 (EMACS_TIME_SIGN): New macro.
3131 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3132 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3133 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3134 (make_timeval, make_lisp_time, decode_time_components): New decls.
3135 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3136 that it mishandled time_t overflow. You can't compare by subtracting!
3137 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3138 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3140 * term.c: Include <sys/time.h>.
3141 (timeval_to_Time): New function, for proper overflow wraparound.

3144 * undo.c (record_first_change): Support higher-resolution time stamps
3146 (Fprimitive_undo): Use them when restoring time stamps.
3148 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3149 (w32_get_internal_run_time):
3150 Port to higher-resolution Emacs time stamps.
3151 (ltime): Now accepts single 64-bit integer, as that's more convenient
3154 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3156 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3157 for compatibility with pselect. Support ns-resolution time stamps.
3159 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3161 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3162 Check for time stamp overflow, and support ns-resolution time stamps.
3164 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3165 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3166 (timeval_subtract): Remove; no longer needed.
3167 (XTflash, XTring_bell, x_wait_for_event):
3168 Port to ns-resolution time stamps. Don't assume time_t is signed.
3170 2012-06-22 Chong Yidong <cyd@gnu.org>
3172 * xdisp.c (x_consider_frame_title): Revert last change.
3174 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3176 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3177 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3178 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3179 staticidx goes up to 1597 out of 1600 = 0x640.)
3181 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3183 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3184 Otherwise, the umask might be mistakenly 0 while handling input signals.
3186 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3188 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
3190 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
3192 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
3193 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
3194 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3195 access to `contents' member of Lisp_Vector objects with AREF and ASET
3198 2012-06-19 Chong Yidong <cyd@gnu.org>
3200 * frame.c (delete_frame): When selecting a frame on a different
3201 text terminal, do not alter the terminal's top-frame.
3203 * xdisp.c (format_mode_line_unwind_data): Record the target
3204 frame's selected window and its terminal's top-frame.
3205 (unwind_format_mode_line): Restore them.
3206 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3208 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3209 since tty frames can be explicitly named.
3210 (prepare_menu_bars): Likewise.
3212 * term.c (Ftty_top_frame): New function.
3214 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3216 Port byte-code-meter to modern targets.
3217 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3218 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3219 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3220 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3221 (METER_1, METER_2): Simplify.
3223 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3225 * data.c (Fdefalias): Return `symbol' (bug#11686).
3227 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3229 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3230 gets killed during executing of this function (Bug#11665).
3231 Try to always return Qt when the buffer has been actually killed.
3232 (Vkill_buffer_query_functions): In doc-string say that functions
3233 run by this hook should not change the current buffer.
3235 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3237 Fix recently-introduced process.c problems found by static checking.

3453 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3454 Use an inline function on all platforms when using the union type,
3455 since this is simpler and 'static inline' can be used portably

3599 * doprnt.c (doprnt): Truncate multibyte char correctly.
3600 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3601 would mishandle a string argument "Xc" if X was a multibyte

3686 and 'double' in a couple of places.

3690 * xdisp.c (handle_stop): Detect whether we have overlay strings
3691 loaded by testing it->current.overlay_string_index to be
3692 non-negative, instead of checking whether n_overlay_strings is
3693 positive. (Bug#11587)

3710 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3711 for the duration of call to load_charset, to avoid problems with

3715 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3716 decrement the inhibition flag, instead of just setting or

3722 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3723 This #undef was "temporary" in 2000; it is no longer needed
3724 now that '#define static' has gone away.
3725 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3726 (gray_bitmap_bits): Remove; no longer needed.
3727 All uses replaced with definiens.
3728 * xterm.c: Include "bitmaps/gray.xbm".
3730 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3732 Clean up __executable_start, monstartup when --enable-profiling.
3733 The following changes affect the code only when profiling.
3734 * dispnew.c (__executable_start): Rename from safe_bcopy.
3735 Define only on platforms that need it.
3736 * emacs.c: Include <sys/gmon.h> when profiling.
3737 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3738 (__executable_start): Remove decl, since lisp.h does it now.
3739 (safe_bcopy): Remove decl; no longer has that name.
3740 (main): Coalesce #if into single bit of code, for simplicity.
3741 Cast pointers to uintptr_t, since standard libraries want integers
3743 * lisp.h (__executable_start): New decl.
3745 2012-05-31 Glenn Morris <rgm@gnu.org>
3747 * image.c (Fimagemagick_types): Doc fix.
3749 2012-05-30 Jim Meyering <meyering@redhat.com>
3751 * callproc.c (Fcall_process_region): Include directory component

3763 * data.c (Fdefalias): Purify definition, except for keymaps.
3764 (Qdefun): Move from eval.c.
3765 * lisp.h (Qdefun): Remove.
3766 * lread.c (read1): Tiny simplification.
3768 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3770 Do not create empty overlays with the evaporate property (Bug#9642).
3771 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3772 Bug#9642, but explicitly check that the buffer the overlay would
3773 be moved to is live and rearrange lines to make sure that errors
3774 will not put the overlay in an inconsistent state.
3775 (Fdelete_overlay): Cosmetics.
3777 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3779 * w32term.c (my_bring_window_to_top): New function.
3780 (x_raise_frame): Use handle returned by DeferWindowPos, which
3781 could be different from the original one.

3785 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3786 by calling BringWindowToTop.
3788 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3789 (WM_EMACS_END): Increase by one.
3791 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3793 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3794 This avoids undefined behavior that might cause the eassert
3795 to not catch an out-of-range value.
3797 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3799 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3800 Update dependencies.
3802 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3804 * bidi.c (bidi_mirror_char): Fix last change.

3809 when referring to sectname field in printf format.
3811 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3813 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3814 Only r_alloc_inhibit_buffer_relocation needed to be added;
3815 the others were already declared.
3817 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3818 before checking whether it's out of range. Put the check inside
3820 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3822 2012-05-27 Ken Brown <kbrown@cornell.edu>
3824 * callproc.c (Fcall_process): Restore a line that was accidentally
3825 commented out in the 2011-02-13 change (bug#11547).
3827 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3829 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3830 defined on ralloc.c.
3832 * buffer.c [REL_ALLOC]: Remove prototypes of
3833 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3834 they are now on lisp.h.
3836 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3838 * search.c (search_buffer): Use it to inhibit relocation of buffer
3839 text while re_search_2 is doing its job, because re_search_2 is
3840 passed C pointers to buffer text. (Bug#11519)
3842 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3845 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3846 state after an additional call to move_it_in_display_line_to, keep
3847 the values of it->max_ascent and it->max_descent found for the
3849 (pos_visible_p): Revert the comparison against bottom_y to what it
3850 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3853 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3855 Fix coding-related core dumps with gcc -ftrapv.
3856 The code was computing A - B, where A and B are pointers, and B is
3857 random garbage. This can lead to core dumps on platforms that
3858 have special pointer registers, and it also leads to core dumps on
3859 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3860 A - B only when B is initialized properly.
3861 * coding.c (coding_set_source, coding_set_destination): Return void.
3862 (coding_change_source, coding_change_destinations): New functions,
3863 with the old behaviors of coding_set_source and coding_set_destination.
3864 All callers that need an offset changed to use these new functions.
3866 2012-05-26 Glenn Morris <rgm@gnu.org>
3868 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3870 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3872 Extend mouse support on W32 text-mode console.
3873 * xdisp.c (draw_row_with_mouse_face):
3874 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3876 * w32console.c: Include window.h.
3877 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3879 (initialize_w32_display): Initialize mouse-highlight data.
3881 * w32inevt.c: Include termchar.h and window.h.
3882 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3883 moves, call note_mouse_highlight. If help_echo changed, call
3884 gen_help_event to produce help-echo message in the echo area.
3885 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3888 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3890 * lread.c (read1): Simplify slightly to avoid an overflow warning
3891 with GCC 4.7.0 on x86-64.
3893 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3895 * bidi.c (bidi_mirror_char): Revert last change: an int is
3896 definitely wide enough here.
3898 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3900 Fix integer width and related bugs (Bug#9874).
3901 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3902 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3903 (string_bytes, check_sblock, allocate_string_data):

3906 (make_string_from_bytes, make_specified_string)
3907 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3908 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3910 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3911 (allocate_pseudovector):
3912 Use int, not EMACS_INT, where int is wide enough.
3913 (inhibit_garbage_collection, Fgarbage_collect):
3914 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3915 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3916 int might not be wide enough.
3917 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3918 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

3920 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3921 (bidi_level_of_next_char, bidi_move_to_visually_next):
3922 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3923 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3924 (Fkill_buffer, Fset_buffer_major_mode)

3928 (overlay_strings, recenter_overlay_lists)
3929 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3930 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3931 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3932 (Foverlay_recenter, last_overlay_modification_hooks_used)
3933 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3934 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3935 (validate_region): Omit unnecessary test for b <= e,
3936 since that's guaranteed by the previous test.
3937 (adjust_overlays_for_delete): Avoid pos + length overflow.
3938 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3939 (report_overlay_modification):
3940 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3941 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3942 Omit pointer cast, which isn't needed anyway, and doesn't work
3943 after the EMACS_INT -> ptrdiff_t change.
3944 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3945 * buffer.h: Adjust decls to match defn changes elsewhere.

3949 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3950 not int, to avoid needless 32-bit limit on 64-bit hosts.
3951 (exec_byte_code): Use tighter memory-full test, one that checks
3952 for alloca overflow. Don't compute the address of the object just
3953 before an array, as that's not portable. Use EMACS_INT, not
3954 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3955 * callint.c (Fcall_interactively):
3956 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3957 * callproc.c (call_process_kill, Fcall_process):
3958 Don't assume pid_t fits into an Emacs fixnum.

3967 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3968 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3969 (casify_object): Avoid integer overflow when overallocating buffer.
3970 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3971 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3972 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3973 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3974 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3975 integers are now checked earlier. All uses replaced with XINT.
3977 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3978 For CCL_MapSingle, check that content and value are in int range.
3979 (ccl_driver, Fregister_code_conversion_map):
3980 Check that Vcode_version_map_vector is a vector.
3981 (resolve_symbol_ccl_program): Check that vector header is in range.
3982 Always copy the vector, so that we can check its contents reliably
3983 now rather than having to recheck each instruction as it's being
3984 executed. Check that vector words fit in 'int'.
3985 (ccl_get_compiled_code, Fregister_ccl_program)
3986 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3987 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3988 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3989 contents are in range.
3990 (Fccl_execute_on_string): Check that status is in range.
3991 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3992 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3993 Accept and return EMACS_INT, not int, because callers can pass values
3995 (c_string_width, strwidth, lisp_string_width, chars_in_text)
3996 (multibyte_chars_in_text, parse_str_as_multibyte)
3997 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
3998 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3999 (string_escape_byte8, Fget_byte):
4000 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4001 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4002 avoid mishandling large integers.
4003 * character.h: Adjust decls to match defn changes elsewhere.
4004 * charset.c (load_charset_map_from_file, find_charsets_in_text)

4009 Don't assume fixnum fits in int.
4010 (load_charset_map_from_vector, Fmap_charset_chars):

4012 (Fdefine_charset_internal): Check ranges here, more carefully.
4013 Don't rely on undefined behavior with signed left shift overflow.
4014 Don't assume unsigned int fits into fixnum, or that fixnum fits
4015 into unsigned int. Don't require max_code to be a valid fixnum;
4016 that's not true for gb10830 4-byte on a 32-bit host. Allow
4017 invalid_code to be a cons, for the same reason. Require code_offset
4018 to be a character. Avoid int overflow if max_char is close
4020 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4021 this is intended anyway and avoids some undefined behavior.
4022 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4023 INDEX_TO_CODE_POINT, as that's what it expects.
4024 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4025 * charset.h (DECODE_CHAR): Return int, not unsigned;
4026 this is what was intended anyway, and it avoids undefined behavior.
4027 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4028 integer-overflow issues.
4029 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4030 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4031 where the argument is EMACS_INT, and this behavior is not intended.
4032 * chartab.c (Fmake_char_table, Fset_char_table_range)
4033 (uniprop_get_decoder, uniprop_get_encoder):
4034 Don't assume fixnum fits in int.
4035 * cmds.c (move_point): New function, that does the gist of
4036 Fforward_char and Fbackward_char, but does so while checking
4037 for integer overflow more accurately.
4038 (Fforward_char, Fbackward_char): Use it.
4039 (Fforward_line, Fend_of_line, internal_self_insert)
4040 (internal_self_insert):
4041 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4042 Fix a FIXME, by checking for integer overflow when calculating
4043 target_clm and actual_clm.

4073 (Funencodable_char_position, Fcheck_coding_systems_region)
4074 (get_translation, handle_composition_annotation, consume_chars):
4075 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4076 (consume_chars): Rewrite to not calculate an address outside buffer.
4077 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
4078 Don't access memory outside of the args array.
4079 (Fdefine_coding_system_internal): Check for charset-id overflow.
4080 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4081 result of ENCODE_CHAR.
4082 * coding.h: Adjust decls to match defn changes elsewhere.
4083 (struct coding_system):
4084 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4099 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4100 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
4101 Do not attempt to compute the address of the object just before a
4102 buffer; this is not portable.
4104 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4105 (Faset): Use int, not EMACS_INT, where int is wide enough.
4106 (Fstring_to_number): Don't assume fixnums fit in int.

4114 (xd_signature, xd_append_arg, xd_retrieve_arg, Fdbus_message_internal)

4850 proceed to consider_string_end without incrementing string
4851 position. Don't increment display vector index past the end of
4852 the display vector. (Bug#11417)
4853 (pos_visible_p): Don't report a position visible when move_it_to
4854 stopped at the last line of window, which happens to be scanned
4855 backwards by the bidi iteration. (Bug#11464)
4857 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4859 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4860 and right-margin display specs even if the spec is invalid or we
4861 are on a TTY, and thus unable to display on the fringes.
4862 That's because the text with the property will not be displayed anyway,
4863 so we need to signal to the caller that this is a "replacing"
4864 display spec. This fixes display when the spec is invalid or we
4867 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4869 * unexaix.c (make_hdr): Fix typo in prototype.
4870 This bug broke the build on AIX. Problem reported by Gilles Pion.
4872 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4874 * keyboard.c (kbd_buffer_get_event): Read special events also in
4875 batch mode. (Bug#11415)
4877 2012-05-12 Glenn Morris <rgm@gnu.org>
4879 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4881 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4883 * lisp.mk (lisp): Add newcomment.elc.
4885 2012-05-12 Glenn Morris <rgm@gnu.org>
4887 * Makefile.in (MKDIR_P): New, set by configure.
4888 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4890 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4892 Remove unused function hourglass_started.
4893 * dispextern.h (hourglass_started):
4894 * w32fns.c (hourglass_started):
4895 * xdisp.c (hourglass_started): Remove.
4897 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4899 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4900 Update dependencies.
4902 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4904 * xgselect.c (xg_select): Put maxfds+1 into a var.
4905 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4907 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4909 2012-05-10 Dave Abrahams <dave@boostpro.com>
4911 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4912 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4914 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4916 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4917 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4918 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4919 Initialize xd_registered_buses.
4921 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4923 Untag more efficiently if USE_LSB_TAG.
4924 This is based on a proposal by YAMAMOTO Mitsuharu in
4925 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4926 For an admittedly artificial (nth 8000 longlist) benchmark on
4927 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4928 Emacs's overall text size by 1%.
4929 * lisp.h (XUNTAG): New macro.
4930 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4931 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4932 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4933 * eval.c (Fautoload):
4934 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4935 * frame.h (XFRAME): Use XUNTAG.
4937 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4938 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4939 Remove unportable assumptions about print widths of types like
4941 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4942 intptr_t when converting between pointer and integer, to avoid GCC
4943 warnings about wrong width.
4945 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4947 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4948 stack for each reader_thread, instead of defaulting to 8MB
4949 determined by the linker. This avoids failures in creating
4950 subprocesses on Windows 7, see the discussion in this thread:
4951 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4953 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4955 Fix up display of the *Minibuf-0* buffer in the mini window.
4956 * keyboard.c (read_char): Don't clear the echo area if there's no
4958 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4959 contents of *Minibuf-0*) if there's no message displayed in its stead.
4961 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4963 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4966 2012-05-06 Chong Yidong <cyd@gnu.org>
4968 * lisp.mk (lisp): Update.
4970 2012-05-05 Jim Meyering <meyering@redhat.com>
4972 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4974 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4976 * data.c (PUT_ERROR): New macro.
4977 (syms_of_data): Use it. Add new error type `user-error'.
4978 * undo.c (user_error): New function.
4979 (Fprimitive_undo): Use it.
4980 * print.c (print_error_message): Adjust print style for `user-error'.
4981 * keyboard.c (user_error): New function.
4982 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4984 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4986 Do not limit current-time-string to years 1000..9999.
4987 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4988 (Fcurrent_time_string): Support any year that is supported by the
4989 underlying localtime representation. Don't use asctime, as it
4990 has undefined behavior for years outside the range -999..9999.
4992 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4994 Fix race conditions involving setenv, gmtime, localtime, asctime.
4995 Without this fix, interrupts could mess up code that uses these
4996 nonreentrant functions, since setting TZ invalidates existing
4997 tm_zone or tzname values, and since most of these functions return
4998 pointers to static storage.
4999 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5000 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5001 Grow the critical sections to include not just invoking
5002 localtime/gmtime, but also accessing these functions' results
5003 including their tm_zone values if any, and any related TZ setting.
5004 (format_time_string): Last arg is now struct tm *, not struct tm **,
5005 so that the struct tm is saved in the critical section.
5006 All callers changed. Simplify allocation of initial buffer, partly
5007 motivated by the fact that memory allocation needs to be outside
5008 the critical section.
5010 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5012 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5013 with RESET_INTERVAL.
5015 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5016 Remove duplicated buffer name initialization.
5018 2012-05-02 Jim Meyering <jim@meyering.net>
5020 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5022 * xfns.c (x_window): Use xstrdup (Bug#11375).
5024 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5026 * xdisp.c (pos_visible_p): If already at a newline from the
5027 display string before the 'while' loop, don't walk back the glyphs
5028 from it3.glyph_row. Solves assertion violation when the display
5029 string begins with a newline (egg.el). (Bug#11367)
5031 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5033 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5036 2012-05-01 Glenn Morris <rgm@gnu.org>
5038 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5039 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5040 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5041 All were removed before 23.1.
5043 * dispnew.c: Remove HAVE_LIBNCURSES test;
5044 it is always true on relevant platforms.
5046 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5047 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5049 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5051 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5053 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5054 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5057 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5059 Do not avoid creating empty evaporating overlays (Bug#9642).
5060 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5061 That is, do not delete an evaporating overlay if it becomes
5062 empty after its bounds are adjusted to fit within its buffer.
5063 This fix caused other problems, and I'm reverting it until we get
5064 to the bottom of them.
5066 2012-04-27 Chong Yidong <cyd@gnu.org>
5068 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5070 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5072 * xdisp.c (pos_visible_p): If the window start position is beyond
5073 ZV, start the display from buffer beginning. Prevents assertion
5074 violation in init_iterator when the minibuffer window is scrolled
5077 * window.c (window_scroll_pixel_based): Likewise.
5079 2012-04-27 Chong Yidong <cyd@gnu.org>
5081 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5083 2012-04-27 Glenn Morris <rgm@gnu.org>
5085 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5086 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5088 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5090 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5091 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5093 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5095 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5096 display element, check also the underlying string or buffer
5097 character. (Bug#11341)
5099 * w32menu.c: Include w32heap.h.
5100 (add_menu_item): If the call to AppendMenuW (via
5101 unicode_append_menu) fails, disable Unicode menus only if we are
5102 running on Windows 9X/Me.
5104 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5106 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5107 (xgetint): Add missing shift for LSB tags.
5109 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5111 * keyboard.c (read_char): Don't wipe echo area for select window
5112 events: These might get delayed via `mouse-autoselect-window'
5115 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5117 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5118 manipulation of :loaded-from data.
5120 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5122 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5123 now a cons (bug#11311).
5125 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5127 Do not create empty overlays with the evaporate property (Bug#9642).
5128 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5129 if it becomes empty after its bounds are adjusted to fit within
5130 its buffer. Without this fix, in a nonempty buffer (let ((o
5131 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5132 yields an empty overlay that has the evaporate property, which is
5133 not supposed to happen.
5135 Fix minor GTK3 problems found by static checking.
5136 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5137 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5138 (struct _EmacsFixedClass, emacs_fixed_get_type):

5141 (emacs_fixed_class_init): Omit unused local.
5142 (emacs_fixed_child_type): Remove; unused.

5146 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5147 (EMACS_FIXED_GET_CLASS): Remove; unused.
5148 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5150 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5151 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5153 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5155 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5156 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5157 (__malloc_size_t, __malloc_ptrdiff_t):
5158 Remove. All uses removed, replaced by the definiens if needed,
5159 since we can assume C89 or better now.
5160 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5161 (protect_malloc_state, align, get_contiguous_space)
5162 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5168 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5169 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5170 Define using prototypes, not old style.
5171 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5172 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5173 (align): Don't assume that signed integer overflow wraps around.
5174 Omit unused local var.
5175 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5176 (_free_internal_nolock, memalign, mallochook, reallochook):
5177 Omit no-longer-needed casts.
5178 (valloc): Use getpagesize, not __getpagesize.

5180 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5182 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5184 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

5229 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5231 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
5232 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
5233 Do not assume ptrdiff_t is the same width as 'int'.
5235 * alloc.c: Handle unusual debugging option combinations.
5236 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5237 since the two debugging options are incompatible.
5238 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

5241 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5248 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5250 * sysdep.c [__FreeBSD__]: Minor cleanups.
5251 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5252 Use Emacs indenting style more consistently. Avoid some casts.
5253 Use 'double' consistently rather than mixing 'float' and 'double'.
5255 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5257 * sysdep.c (list_system_processes, system_process_attributes):
5258 Add implementation for FreeBSD (Bug#5243).

5292 row, return zero immediately.
5293 (try_cursor_movement): If inside continuation line, don't back up
5294 farther than the first row after the header line, if any.
5295 Don't consider the header-line row as "partially visible", even if
5296 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5298 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5312 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
5313 -Wunused-result, -Wunused-variable. This should go away once
5314 the Emacs and Gnulib regex code is merged.

5332 Fix minor alloc.c problems found by static checking.
5333 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5334 New extern decls, to avoid calling undeclared functions.
5335 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5336 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5337 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5338 (NEED_MEM_INSERT): New macro.
5339 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5340 Remove one incorrect comment and fix another.

5346 (r_alloc_sbrk): Now static.
5348 Improve ralloc.c interface checking.
5349 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

5353 [REL_ALLOC]: ... to here, to check interface.
5354 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5355 Remove decls. This fixes an "It stinks!".
5357 * alloc.c (which_symbols): Fix alignment issue / type clash.
5359 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5361 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5372 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5374 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5375 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5376 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5377 * s/netbsd.h, s/sol2-6.h:
5378 Remove definition of GC_MARK_STACK, since the default now works.
5379 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5380 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5381 no longer the default.
5382 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5384 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5386 * lread.c (lisp_file_lexically_bound_p):

5394 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5396 * nsterm.m (constrainFrameRect): Always constrain when there is only
5397 one screen (Bug#10962).
5399 2012-04-13 Ken Brown <kbrown@cornell.edu>

5407 2012-04-11 Daniel Colascione <dancol@dancol.org>
5409 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5410 against is gone. It's better to use vfork now so that when Cygwin
5411 gains a new, working vfork, we use it automatically (bug#10398).
5413 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5429 (handle_interrupt): Use it.
5431 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5433 * w32.c (w32_delayed_load): Record the full path of the library
5434 being loaded (bug#10424).
5436 2012-04-09 Glenn Morris <rgm@gnu.org>
5438 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5439 not just in the obarray, before snarfing them. (Bug#11036)
5441 * Makefile.in ($(leimdir)/leim-list.el):
5442 Pass EMACS rather than BUILT_EMACS.

5451 Add convenience `GNUTLS_LOG2i' macro.
5453 * gnutls.c (gnutls_log_function2i): Convenience log function.
5454 (emacs_gnutls_read): Use new log functions,
5455 `gnutls_handshakes_tried' process member, and

5457 attempts per process (connection).
5459 2012-04-09 Chong Yidong <cyd@gnu.org>
5461 * eval.c (Fuser_variable_p, user_variable_p_eh)

5466 * minibuf.c (Fread_variable): Callers changed.
5468 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5470 * xdisp.c (set_cursor_from_row): If the display string appears in
5471 the buffer at position that is closer to point than the position
5472 after the display string, display the cursor on the first glyph of
5473 the display string. Fixes cursor display when a 'display' text
5474 property immediately follows invisible text. (Bug#11094)
5476 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5478 composite.c: use 'double' consistently
5479 * composite.c (get_composition_id): Use 'double' consistently
5480 instead of converting 'float' to 'double' and vice versa; this is
5481 easier to understand and avoids a GCC warning.
5483 2012-04-09 Glenn Morris <rgm@gnu.org>
5485 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5486 preparation for dumping it with emacs. (Bug#4789)

5508 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5509 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5510 objects, as mark_maybe_pointer will catch them otherwise.
5511 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5512 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5514 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5516 Fix typo that broke non-Windows builds.
5517 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5519 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5521 Support building on MS-Windows with libxml2.
5523 * makefile.w32-in (OBJ2): Add xml.$(O).
5524 (GLOBAL_SOURCES): Add xml.c.
5525 ($(BLD)/xml.$(O)): New dependency list.
5527 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5528 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5529 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5530 [!WINDOWSNT]: New macros.
5531 (init_libxml2_functions, libxml2_loaded_p): New functions.
5532 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5533 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5534 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5535 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5537 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5538 Call init_libxml2_functions before calling libxml2 functions.
5539 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5541 * emacs.c: Don't include libxml/parser.h.
5542 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5543 xmlCleanupParser directly.
5545 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5547 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5549 * indent.c (Fvertical_motion): If there is a display string at
5550 point, use it.vpos to compute how many lines to backtrack after

5555 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5556 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5557 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5558 macros related to unification of CJK characters. For the details,
5559 see the discussion following the message here:
5560 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5562 2012-04-04 Chong Yidong <cyd@gnu.org>
5564 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5566 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5568 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

5576 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5578 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5579 position we get to after a call to move_it_to fails the
5580 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5581 only if we wind up in a string from display property. (Bug#11063)
5583 * window.c (Fdelete_other_windows_internal): Invalidate the row
5584 and column information about mouse highlight, so that redisplay
5585 restores it after reallocating the glyph matrices. (Bug#7464)
5587 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5588 string comes from a `display' text property, use the buffer
5589 position of that property as if we actually saw that position in
5591 (move_it_by_lines): Remove the assertion that
5592 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5593 violated when there's a before-string at the beginning of a line.
5596 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5598 * xdisp.c (append_space_for_newline): If the default face was
5599 remapped, use the remapped face for the appended newline.
5600 (extend_face_to_end_of_line): Use the remapped default face for
5601 extending the face to the end of the line.
5602 (display_line): Call extend_face_to_end_of_line when the default
5603 face was remapped. (Bug#11068)
5605 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5607 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

5627 handle-select-window too (Bug#8996).
5629 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5631 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5633 2012-03-25 Kenichi Handa <handa@m17n.org>
5635 * dispextern.h (struct glyph): Change the bit length of
5636 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5638 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5640 * s/ms-w32.h (tzname): Include time.h before redirecting to
5641 _tzname. Fixes the MSVC build. (Bug#9960)
5643 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5645 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5648 * xterm.c (XTread_socket): Only modify handling_signal if
5649 !SYNC_INPUT. (Bug#11080)
5651 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5653 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5654 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5655 when fetching a multibyte character consumes more bytes than
5656 CHAR_BYTES returns, due to unification of CJK characters in
5657 string_char. (Bug#11073)
5659 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5661 * process.c (wait_reading_process_output): Handle pty disconnect

5673 2012-03-21 Chong Yidong <cyd@gnu.org>
5675 * xfaces.c (Vface_remapping_alist): Doc fix.
5677 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5679 * w32proc.c (Fw32_set_console_codepage)
5680 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5693 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5695 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5696 that is not from display property, accept the row as a "cursor
5697 row" if one of the string's character has a non-nil `cursor'
5698 property. Fixes cursor positioning when there are newlines in
5699 overlay strings, e.g. in icomplete.el. (Bug#11035)
5701 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5703 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

5707 * eval.c (inhibit_lisp_code): Rename from
5708 inhibit_window_configuration_change_hook; move from window.c.
5710 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5711 * window.c (run_window_configuration_change_hook)
5712 (syms_of_window): Callers changed.
5714 2012-03-11 Chong Yidong <cyd@gnu.org>

5723 is visible (Bug#10955).
5725 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5727 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5729 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5731 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5732 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5735 2012-03-03 Glenn Morris <rgm@gnu.org>
5737 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5739 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5741 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5742 position past the first glyph_row that ends at ZV. (Bug#10902)
5743 (redisplay_window, next_element_from_string): Fix typos in
5745 (redisplay_window): Pass to move_it_vertically the margin in
5746 pixels, not in screen lines.
5748 2012-03-02 Glenn Morris <rgm@gnu.org>
5750 * buffer.c (buffer-list-update-hook): Doc fix.
5752 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5754 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5755 push_it before setting up the iterator for the first overlay
5756 string, even if we have an empty string loaded.
5757 (next_overlay_string): If there's an empty string on the iterator
5758 stack, pop the stack. (Bug#10903)
5760 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5762 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5763 Suggested by Stefan Monnier in
5764 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5765 * alloc.c (widen_to_Lisp_Object): New static function.
5766 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5767 and widening them to Lisp_Objects. This would work even if
5768 USE_LSB_TAG is defined and wide integers are used, which might
5769 happen in a future version of Emacs.
5771 2012-02-25 Chong Yidong <cyd@gnu.org>
5773 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5776 * xselect.c (Fx_selection_exists_p): Doc fix.
5777 (x_clipboard_manager_save_all): Print an informative message
5778 before saving to clipboard manager.
5780 2012-02-24 Chong Yidong <cyd@gnu.org>
5782 * keyboard.c (process_special_events): Handle all X selection
5783 requests in kbd_buffer, not just the next one (Bug#8869).

5810 when computing $valmask.
5812 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5813 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5814 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5815 It's useless in that case, and it can cause problems on hosts
5816 that allocate halves of EMACS_INT values separately.
5817 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5818 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5819 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5820 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5821 it avoids undefined behavior on hosts where shifting right by more
5822 than the word width has undefined behavior.

5904 * buffer.c (Fbuffer_local_variables)
5905 (buffer_lisp_local_variables): Handle unbound vars correctly;

5908 2012-02-07 Glenn Morris <rgm@gnu.org>
5910 * image.c (Fimagemagick_types): Doc fix.

5948 * character.c (char_width): Return EMACS_INT, not int.
5949 (char_width, c_string_width): Check for overflow when
5950 computing the width; this is possible now that individual
5951 characters can have unbounded width. Problem introduced

6610 to 4 (xorl, subq, cmpq, setbe).
6611 * alloc.c (pure): Always extern now, since that's the
6612 VIRT_ADDR_VARIES behavior.
6613 (PURE_POINTER_P): Use a single comparison, not two, for
6614 consistency with the new puresize.h.

6624 behave as if the cursor position were at the window margin.
6626 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6627 and the cursor position is out of bounds, behave as if the cursor
6628 position were at the window margin. (Bug#10075)

6658 * dispnew.c (verify_row_hash): Call row_hash for computing the
6659 hash code of a row, instead of duplicating code from xdisp.c.
6661 * dispextern.h (row_hash): Add prototype.
6663 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6665 * frame.c (delete_frame): Don't delete the terminal when the last

6697 * image.c (imagemagick_load_image): Fix typo.
6699 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6701 * xdisp.c (display_line): Move the call to
6702 highlight_trailing_whitespace before the call to

6769 The trivial performance wins aren't worth the portability hassles; see
6770 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6772 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6777 (adjust_intervals_for_deletion): Undo previous change,
6778 making these static again.
6779 (offset_intervals, temp_set_point_both, temp_set_point)

6801 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
6802 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
6803 of temacs in GUI mode.
6805 2011-11-07 Martin Rudalics <rudalics@gmx.at>
6807 * window.h: Declare delete_all_child_windows instead of

6820 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6821 This is also needed for porting to any host where GC_MARK_STACK is
6822 not GC_MAKE_GCPROS_NOOPS.
6823 (which_symbols): Use it.
6825 2011-11-07 Kenichi Handa <handa@m17n.org>

6838 * xmenu.c (cleanup_widget_value_tree): New function.
6839 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6842 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
6844 Fix some portability problems with 'inline'.

6846 (window_box_width, window_box_left, window_box_left_offset)
6847 (window_box_right, window_box_right_offset): Declare extern.
6848 Otherwise, these inline functions do not conform to C99 and
6849 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6850 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6851 * intervals.c (adjust_intervals_for_insertion)
6852 (adjust_intervals_for_deletion): Now extern, because otherwise the
6853 extern inline functions 'offset_intervals' couldn't refer to it.
6854 (static_offset_intervals): Remove.
6855 (offset_intervals): Rewrite using the old contents of
6856 static_offset_intervals. The old version didn't conform to C99
6857 because an extern inline function contained a reference to an
6858 identifier with static linkage.
6860 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6862 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6880 (Fwindow_vscroll): Doc fix.
6881 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6882 argument, since it makes no sense to pass a live window and for
6883 consistency with window-child.

6911 (unwind_create_frame): New function (Bug#9943).
6912 (Fx_create_frame): Restructure code to be more similar to the one in
6913 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6914 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6915 Move terminal->reference_count++ just before making the frame official

7029 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7030 so that this new function doesn't get optimized away by a
7031 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7033 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
7035 * frame.h (MOUSE_HL_INFO): Remove excess parens.

7056 Not clear what it was for, and it causes various bugs. (Bug#9839)
7058 2011-10-28 Eli Zaretskii <eliz@gnu.org>
7060 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

7062 condition to clear the mouse face.
7064 2011-10-28 Chong Yidong <cyd@gnu.org>
7066 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

7091 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7093 (w32font_open_internal, compute_metrics):
7094 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7095 instead of calling the "wide" APIs directly.
7097 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
7099 * w32.h (syms_of_w32font): Add prototype.
7101 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
7103 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)

7105 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

7110 * process.c (make_process): Set gnutls_state to NULL.
7112 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7113 non-NULL, regardless of GNUTLS_INITSTAGE.
7114 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7115 an error. Set process slots as soon as we allocate them.

7161 current character, check also for next_en_type being WEAK_EN.
7162 (bidi_resolve_weak): Don't enter the expensive loop if the current
7163 position is before next_en_pos. Record the bidi type of the first
7164 non-ET, non-BN character we find, in addition to its position.
7165 (bidi_level_of_next_char): Invalidate next_en_type when
7166 next_en_pos is over-stepped.
7168 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7170 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7171 * editfns.c: Rewrite current-time-zone so that it invokes
7172 the equivalent of (format-time-string "%Z") to get the time zone name.
7173 This fixes a bug when the time zone name contains characters that
7174 need converting from the system time locale to Emacs internal format.
7175 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7176 that patch fixed format-time-string to do the conversion, but
7177 I forgot to fix current-time-zone.
7178 (format_time_string): New function, containing most of
7179 what Fformat_time_string used to contain.
7180 (Fformat_time_string): Rewrite in terms of format_time_string.
7181 This doesn't change this function's behavior.
7182 (current-time-zone): Rewrite to use format_time_string.
7183 This fixes the bug reported by Michael Schierl in
7184 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7185 Jason Rumney's 2007-06-07 change worked around this bug, but
7187 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7189 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7191 * xdisp.c (start_display): If the character at POS is displayed
7192 via a display vector, reset IT->current.dpvec_index to zero.
7193 (try_window_reusing_current_matrix): If a line ends in a display
7194 vector or the next line starts in a display vector, continue
7195 redrawing the window even though the character position of
7196 start_row was reached.
7199 2011-10-18 Chong Yidong <cyd@gnu.org>
7201 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7202 with nobreak-char-display too.
7204 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7206 Fix part 3 of bug#9771.
7207 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7208 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7209 non-neutral characters if the current character is a paragraph
7210 separator (a.k.a. Newline). This avoids running the same
7211 expensive loop twice, once when we consume the preceding newline
7212 and the other time when the line actually needs to be displayed.
7213 Avoid the loop when we see neutrals on the base embedding level
7214 following a character whose directionality is the same as the
7215 paragraph's. This avoids running the expensive loop when a line
7216 ends in a long sequence of neutrals, like control characters.
7217 Add assertion against STRONG_AL type. Slightly rearrange code
7218 that determines the type of a neutral given the first non-neutral
7220 (bidi_level_of_next_char): Set next_en_pos to zero when
7221 invalidating its info.
7223 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7225 * xdisp.c (push_display_prop): Determine whether to record string
7226 or buffer position by IT->string, not by IT->method. Allow
7227 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7228 (move_it_vertically_backward): Don't look for character position
7229 immediately after the newline when in a continuation line.
7232 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7234 * window.c (coordinates_in_window): Rewrite and delabelize
7235 vertical border check. (Bug#5357) (Bug#9618)
7237 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7239 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7240 errors in XSetWindowBorder (bug#9310).
7242 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7244 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7245 avoid crash when xmalloc overrun checking is enabled.
7247 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7249 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7250 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7251 cursor motion with <left> and <right> arrow keys.
7253 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7254 some callers set that themselves.
7256 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7258 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7259 display string and the previous row comes from the same string and
7260 is empty. (Bug#9739) (Bug#9738)
7262 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7264 * doc.c (get_doc_string): Encode file name (bug#9735).
7266 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7268 * bidi.c (bidi_level_of_next_char):
7269 * xdisp.c (get_visually_first_element): Remove old incorrect
7270 comments regarding the Unicode Line Separator character.
7272 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7274 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7276 * alloc.c (Fgc_status): Do not access beyond zombies array
7277 boundary if nzombies > MAX_ZOMBIES.
7278 * alloc.c (dump_zombies): Add missing format specifier.
7280 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7282 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7283 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7285 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7286 Some packages use them to denote characters with modifiers.
7288 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7290 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7291 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7292 matching a pp-number. Rename parameter var to var1.
7294 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7296 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7298 2011-10-08 Glenn Morris <rgm@gnu.org>
7300 * callint.c (Fcall_interactively): Give a more explicit error for the
7301 'c' case with a non-character input. (Bug#8479)
7303 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7305 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7307 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7308 lines that are hscrolled on the left.
7310 * dispnew.c (buffer_posn_from_coords): Account for a possible
7311 presence of header-line. (Bug#4426)
7313 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7315 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7316 Don't advertise functionality which we discourage or doesn't work.
7318 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7320 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7321 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7322 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7323 this makes Emacs dump core during garbage collection on rare
7324 occasions. sizeof is obviously inferior to offsetof here, so
7325 stick with offsetof.
7326 (GC_POINTER_ALIGNMENT): New macro.
7327 (mark_memory): Omit 3rd (offset) arg; caller changed.
7328 Don't assume EMACS_INT alignment is the same as pointer alignment.
7330 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7332 * keyboard.c (read_key_sequence_remapped): New var.
7333 (read_key_sequence): Compute remapping in the right buffer.
7334 (command_loop_1): Use read_key_sequence's remapping directly.
7336 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7338 * dired.c (file_name_completion): Don't expand file name.
7339 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7340 before checking file name handler.
7342 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7343 they've been requested explicitly (bug#9591).
7345 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7347 * keymap.c (Fsingle_key_description): Use make_specified_string
7348 instead of build_string to build string from push_key_description.
7351 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7353 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7354 This fixes a Y2038 bug on 64-bit hosts.
7355 * buffer.c (reset_buffer):
7356 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7357 (Fclear_buffer_auto_save_failure):
7358 Use 0, not -1, to represent an unset failure time, since time_t
7359 might not be signed.
7361 Remove dependency on glibc malloc internals.
7362 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7363 Move back here from lisp.h, but with their new implementations.
7364 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7365 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7366 * charset.c (charset_table_init): New static var.
7367 (syms_of_charset): Use it instead of xmalloc. This removes a
7368 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7369 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7370 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7371 Move back to alloc.c.
7372 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7373 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7375 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7377 * nsterm.m (windowDidResize): Call x_set_window_size only when
7378 ns_in_resize is true. Otherwise set pixelwidth/height and
7379 call change_frame_size (Bug#9628).
7381 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7383 Port --enable-checking=all to Fedora 14 x86-64.
7384 * charset.c (syms_of_charset): Also account for glibc malloc's
7385 internal overhead when calculating the initial malloc maximum.
7387 Port --enable-checking=all to Fedora 14 x86.
7388 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7390 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7391 (overrun_check_realloc, overrun_check_free):
7392 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7393 That way, xmalloc returns a properly-aligned pointer even if
7394 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7395 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7396 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7397 into account when calculating the initial malloc maximum.
7398 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7399 Move here from alloc.c, so that charset.c can use it too.
7400 Properly align; the old code wasn't right for common 32-bit hosts
7401 when configured with --enable-checking=all.
7402 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7403 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7405 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7407 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7410 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7412 * xdisp.c (compute_display_string_end): If there's no display
7413 string at CHARPOS, return -1.
7415 * bidi.c (bidi_fetch_char): When compute_display_string_end
7416 returns a negative value, treat the character as a normal
7417 character not covered by a display string. (Bug#9624)
7419 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7421 * lread.c (Fread_from_string): Fix typo in docstring.
7423 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7425 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7426 newline, reseat the iterator instead of bidi-iterating there one
7427 character at a time. (Bug#9610)
7428 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7429 TO_CHARPOS if the bidi iterator is at base embedding level.
7431 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7433 * lread.c (readevalloop): Use correct code for NBSP.
7434 (read1): Likewise. (Bug#9608)
7436 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7438 * dbusbind.c (Fdbus_register_signal): When service is not
7439 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7441 2011-09-25 Glenn Morris <rgm@gnu.org>
7443 * buffer.c (truncate-lines): Doc fix.
7445 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7447 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7448 (Fset_window_next_buffers): Doc fix.
7450 2011-09-24 Glenn Morris <rgm@gnu.org>
7452 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7454 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7456 Fix minor problems found by static checking.
7457 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7458 * indent.c (Fvertical_motion): Fix == vs = typo.
7460 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7462 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7463 Default value is now t. Doc fix.
7465 * indent.c (Fvertical_motion): Compute and apply the overshoot
7466 logic when moving up, not only when moving down. Fix the
7467 confusing name and values of the it_overshoot_expected variable;
7468 logic changes accordingly. (Bug#9254) (Bug#9549)
7470 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7471 CHARPOS is covered by a display string which includes newlines.
7472 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7473 is covered by a display string with embedded newlines.
7475 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7477 * dbusbind.c (Fdbus_register_signal): Add match rule to
7478 Vdbus_registered_objects_table. (Bug#9581)
7479 (Fdbus_register_method, Vdbus_registered_objects_table):
7482 2011-09-24 Jim Meyering <meyering@redhat.com>
7484 do not ignore write error for any output size
7485 The previous change was incomplete.
7486 While it makes emacs --batch detect the vast majority of stdout
7487 write failures, errors were still ignored whenever the output size is
7488 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7489 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7490 && echo FAIL: ignored write error
7491 FAIL: ignored write error
7492 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7493 && echo FAIL: ignored write error
7494 FAIL: ignored write error
7495 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7497 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7499 * emacs.c (Fkill_emacs): In noninteractive mode exit
7500 non-successfully if a write error occurred on stdout. (Bug#9574)
7502 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7504 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7507 * dispextern.h (struct it): Update the comment documenting what
7510 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7512 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7513 a display string, extend search for cursor position to end of row.
7514 (find_row_edges): If the row ends in a newline from a display
7515 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7516 Handle the case of a display string with multiple newlines.
7517 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7518 non-empty line. Fixes confusing cursor motion with arrow keys at
7519 the beginning of a line that starts with whitespace.
7521 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7523 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7526 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7528 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7531 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7533 * xdisp.c (display_line): Record maximum and minimum buffer
7534 positions even if no glyphs were produced (e.g., by a zero-width
7535 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7536 buffer positions that will be removed from the glyph row because
7538 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7539 column is beyond frame width: don't subtract 1 "pixel" when
7540 computing width of the stretch.
7541 (reseat_at_next_visible_line_start): Undo the change made on
7542 2011-09-17 that saved paragraph information and restored it after
7543 the call to `reseat'. (Bug#9545)
7545 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7547 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7548 and turn window cursor on if cleared (Bug#9415).
7550 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7552 * search.c (boyer_moore): Take unibyte characters from pattern
7553 literally. (Bug#9458)
7555 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7557 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7559 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7561 Fix minor problem found by static checking.
7562 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7563 initialized, to pacify gcc -Wuninitialized.
7565 * fileio.c: Report proper errno when syscall falls.
7566 (Finsert_file_contents): Save and restore errno,
7567 so that report_file_error outputs the correct diagnostic.
7568 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7570 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7572 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7574 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7576 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7577 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7579 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7581 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7582 about the current paragraph and restore it after the call to reseat.
7584 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7585 (bidi_find_paragraph_start): Search back for paragraph beginning
7586 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7587 (bidi_move_to_visually_next): Only trigger paragraph-related
7588 computations when the last character is a newline or at EOB, not
7589 just any NEUTRAL_B. (Bug#9470)
7591 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7592 truncated lines if point is covered by a display string. (Bug#9524)
7594 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7596 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7597 (cons_to_x_long): New function.
7598 (lisp_data_to_selection_data): Use it. Correct the test for
7599 short-versus-long data; it was negated. Break out of vector
7600 loop, for efficiency, when a long datum is discovered.
7602 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7604 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7606 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7608 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7609 GCC PR/17406) by declaring this function with external scope.
7611 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7613 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7614 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7616 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7618 * editfns.c (Fformat): Correctly handle text properties on "%%".
7620 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7622 * xterm.c (x_draw_composite_glyph_string_foreground):
7623 * w32term.c (x_draw_composite_glyph_string_foreground):
7624 * term.c (encode_terminal_code):
7625 * composite.c (composition_update_it, get_composition_id):
7626 * xdisp.c (get_next_display_element)
7627 (fill_composite_glyph_string): Add comments about special meaning
7628 of TAB characters in a composition.
7630 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7632 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7633 This occurs when processing a multibyte format.
7634 Problem reported by Wolfgang Jenker.
7636 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7638 * xdisp.c (try_cursor_movement): Only check for exact match if
7639 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7641 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7643 Remove unused external symbols.
7644 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7645 * xdisp.c (calc_pixel_width_or_height): Now static.
7646 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7647 * indent.c (check_display_width):
7648 * w32term.c: Fix comment to match code.
7649 * xterm.c, xterm.h (x_catching_errors): Remove.
7651 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7653 * xselect.c: Use signed conversions more consistently (Bug#9498).
7654 (selection_data_to_lisp_data): Assume incoming selection data are
7655 signed integers, not unsigned. This is to be consistent with
7656 outgoing selection data, which was modified to use signed integers
7657 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7658 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7659 expects long, not unsigned long.
7661 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7663 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7664 computation of loop end. Reported by Johan Bockgård
7667 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7669 * frame.c (Fother_visible_frames_p): Function deleted.
7671 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7673 * indent.c (compute_motion): Process display vector front to back
7674 rather than the other way around. (Bug#2496)
7676 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7678 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7680 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7682 * minibuf.c (Fread_from_minibuffer): Doc fix.
7684 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7686 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7687 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7689 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7691 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7692 value for non-existent files.
7694 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7696 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7697 set its "size" to -1. This will set the modtime_size field of
7698 the corresponding buffer to -1, which is what
7699 verify-visited-file-modtime expects for files that do not exist.
7702 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7704 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7706 * lisp.h: ... from here. push_key_description is no longer
7707 defined in keyboard.c, so its declaration should not be in
7708 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7709 logically belongs with push_key_description.
7711 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7713 * buffer.h: Include <sys/types.h> instead of <time.h>.
7714 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7715 Problem reported by Herbert J. Skuhra.
7717 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7719 * xml.c (parse_region): Make the parsing work for
7720 non-comment-starting XML files again (bug#9144).
7722 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7724 * image.c (gif_load): Fix calculation of bottom and right corner.
7727 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7729 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7730 redisplay in small windows.
7732 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7734 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7736 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7738 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7739 Operate on live windows only.
7741 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7743 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7745 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7747 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7748 only under bidi iteration.
7750 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7752 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7754 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7756 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7757 Without this fix, the command to link temacs failed due to an
7758 undefined symbol __builtin_isnan. This is because
7759 /usr/include/iso/math_c99.h #defines isnan(x) to
7760 __builtin_isnan(x), but the bundled gcc, which identifies itself
7761 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7763 * floatfns.c (isnan): #undef, and then #define to a clone of
7765 (Fisnan): Always define, since it's always available now.
7766 (syms_of_floatfns): Always define isnan at the Lisp level.
7768 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7770 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7772 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7774 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7775 The previous code assumed that file offsets (off_t values) fit in
7776 EMACS_INT variables, which is not true on typical 32-bit hosts.
7777 The code messed up by falsely reporting buffer overflow in cases
7778 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7779 when "big" contains more than 2**29 bytes, even though this
7780 inserts just one byte and does not overflow the buffer.
7781 (Finsert_file_contents): Store file offsets as off_t
7782 values, not as EMACS_INT values. Check for overflow when
7783 converting between EMACS_INT and off_t. When checking for
7784 buffer overflow or for overlap, take the offsets into account.
7785 Don't use EMACS_INT for small values where int suffices.
7786 When checking for overlap, fix a typo: ZV was used where
7787 ZV_BYTE was intended.
7788 (Fwrite_region): Don't assume off_t fits into 'long'.
7789 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7791 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7793 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7795 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7797 sprintf-related integer and memory overflow issues (Bug#9412).
7799 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7800 (esprintf, exprintf, evxprintf): New functions.
7801 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7802 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7803 (modify_event_symbol): Do not assume that the length of
7804 name_alist_or_stem is safe to alloca and fits in int.
7805 (Fexecute_extended_command): Likewise for function name and binding.
7806 (Frecursion_depth): Wrap around reliably on integer overflow.
7807 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7808 since some callers pass EMACS_INT values.
7809 (Fsingle_key_description): Don't crash if symbol name contains more
7810 than MAX_ALLOCA bytes.
7811 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7812 (get_minibuffer): Arg is now EMACS_INT, not int.
7813 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7814 (esprintf, exprintf, evxprintf): New decls.
7815 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7817 * dbusbind.c (signature_cat): New function.
7818 (xd_signature, Fdbus_register_signal):
7819 Do not overrun buffer; instead, report string overflow.
7821 * dispnew.c (add_window_display_history): Don't overrun buffer.
7822 Truncate instead; this is OK since it's just a log.
7824 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7825 even if the time zone offset is outlandishly large.
7826 Don't mishandle offset == INT_MIN.
7828 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7829 when creating daemon; the previous buffer-overflow check was incorrect.
7831 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7832 which has the guts of the old verror function.
7834 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7835 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7837 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7838 (font_unparse_xlfd): Don't blindly alloca long strings.
7839 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7840 fits in int, when using sprintf. Use single snprintf to count
7841 length of string rather than counting it via multiple sprintfs;
7842 that's simpler and more reliable.
7843 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7844 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7845 sprintf, in case result does not fit in int.
7847 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7848 (fontset_from_font): Print it.
7850 * frame.c (tty_frame_count): Now printmax_t, not int.
7851 (make_terminal_frame, set_term_frame_name): Print it.
7852 (x_report_frame_params): In X, window IDs are unsigned long,
7853 not signed long, so print them as unsigned.
7854 (validate_x_resource_name): Check for implausibly long names,
7855 and don't assume name length fits in 'int'.
7856 (x_get_resource_string): Don't blindly alloca invocation name;
7857 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7860 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7861 (xg_check_special_colors, xg_set_geometry):
7862 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7864 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7865 Use esprintf, not sprintf, in case result does not fit in int.
7867 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7868 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7869 it as a large positive number.
7870 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7871 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7873 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7874 in case result does not fit in int.
7876 * print.c (float_to_string): Detect width overflow more reliably.
7877 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7878 buffer overrun. Don't assume list length fits in 'int'. Treat
7879 print length of 0 as 0, not as infinity; to be consistent with other
7880 uses of print length in this function. Don't overflow print length
7881 index. Don't assume hash table size fits in 'long', or that
7882 vectorlike size fits in 'unsigned long'.
7884 * process.c (make_process): Use printmax_t, not int, to format
7885 process-name gensyms.
7887 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7889 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7890 to avoid potential buffer overrun.
7892 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7893 if X resource line is longer than 512 bytes.
7895 * xfns.c (x_window): Make sprintf buffer a bit bigger
7896 to avoid potential buffer overrun.
7898 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7900 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7902 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7904 Integer overflow fixes for scrolling, etc.
7905 Without these, Emacs silently mishandles large integers sometimes.
7906 For example, "C-u 4294967297 M-x recenter" was treated as if
7907 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7909 * xdisp.c (try_window_id): Check Emacs fixnum range before
7910 converting to 'int'.
7912 * window.c (window_scroll_line_based, Frecenter):
7913 Check that an Emacs fixnum is in range before assigning it to 'int'.
7914 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7915 values converted from Emacs fixnums.
7916 (Frecenter): Don't wrap around a line count if it is out of 'int'
7917 range; instead, treat it as an extreme value.
7918 (Fset_window_configuration, compare_window_configurations):
7919 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7921 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7922 that can exceed INT_MAX. Check that EMACS_INT value is in range
7923 before assigning it to the (possibly-narrower) index.
7924 (match_limit): Don't assume that a fixnum can fit in 'int'.
7926 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7929 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7930 (Fvertical_motion): Don't wrap around LINES values that don't fit
7931 in 'int'. Instead, treat them as extreme values. This is good
7932 enough for windows, which can't have more than INT_MAX lines anyway.
7934 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7936 * Require libxml/parser.h to avoid compilation warning.
7938 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7940 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7941 since this reportedly can destroy thread storage.
7943 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7945 * syntax.c (find_defun_start): Update all cache variables if
7946 exiting early (Bug#9401).
7948 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7950 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7952 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7953 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7954 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7956 * term.c (tty_append_glyph): New function.
7957 (produce_stretch_glyph): Static function and its prototype deleted.
7959 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7962 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7964 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7965 when checking :margin (Bug#9390).
7966 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7967 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7968 so that the name doesn't mislead. All uses changed.
7970 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7972 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7975 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7977 * xdisp.c (move_it_to): Don't bail out early when reaching
7978 position beyond to_charpos, if we are scanning backwards.
7979 (move_it_vertically_backward): When DY == 0, make sure we get to
7980 the first character in the line after the newline.
7982 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7984 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7985 (ccl_driver): Do not generate an out-of-range pointer.
7986 (Fccl_execute_on_string): Remove unnecessary check for
7987 integer overflow, noted by Stefan Monnier in
7988 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7989 Remove a FIXME that didn't need fixing.
7990 Simplify the newly-introduced buffer reallocation code.
7992 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7994 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7996 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7998 Integer and memory overflow issues (Bug#9196).
8000 * doc.c (get_doc_string): Rework so that
8001 get_doc_string_buffer_size is the actual buffer size, rather than
8002 being 1 less than the actual buffer size; this makes xpalloc more
8005 * image.c (x_allocate_bitmap_record, cache_image):
8006 * xselect.c (Fx_register_dnd_atom):
8007 Simplify previous changes by using xpalloc.
8009 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8010 since either will do and ptrdiff_t is convenient with xpalloc.
8012 * charset.c (charset_table_size)
8013 (struct charset_sort_data.priority): Now ptrdiff_t.
8014 (charset_compare): Don't overflow if priorities differ greatly.
8015 (Fsort_charsets): Don't assume list length fits in int.
8016 Check for size-calculation overflow when allocating sort data.
8017 (syms_of_charset): Allocate an initial charset table that is
8018 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8020 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8022 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8023 The actual value is always <= INT_MAX, and leaving it unsigned made
8024 overflow checking harder.
8026 * dispextern.h (struct glyph_matrix.rows_allocated)
8027 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8028 with xpalloc. The values are still always <= INT_MAX.
8030 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8032 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8033 (SAFE_NALLOCA): New macro.
8035 * region-cache.c (struct boundary.pos, find_cache_boundary)
8036 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8037 (set_cache_region, invalidate_region_cache)
8038 (revalidate_region_cache, know_region_cache, region_cache_forward)
8039 (region_cache_backward, pp_cache):
8040 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8041 so that ptrdiff_t * can be passed to xpalloc.
8042 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8043 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8044 (pp_cache): Don't assume cache_len fits in int.
8045 * region-cache.h: Adjust extern decls to match.
8047 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8048 EMACS_INT, since either will do, for xpalloc.
8050 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8051 (xnmalloc, xnrealloc, xpalloc): New functions.
8053 * bidi.c (bidi_shelve_header_size): New constant.
8054 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8055 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8057 * bidi.c (bidi_cache_shrink):
8058 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8060 Don't update size of array until after memory allocation succeeds,
8061 because xmalloc/xrealloc may not return.
8062 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8063 now that we have proper integer overflow checking.
8064 (record_overlay_string, overlay_strings): Catch overflows when
8065 calculating size of overlay_str_buf.
8067 * callproc.c (Fcall_process): Check for size overflow when
8068 calculating size of args2.
8069 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8070 Normally we prefer signed values, but sticking with ptrdiff_t would
8071 require adding more-complicated checks.
8073 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8074 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8075 Redo buffer-overflow calculations to avoid integer overflow.
8076 Add a FIXME comment where memory seems to be over-allocated.
8078 * character.c (Fstring): Check for size-calculation overflow.
8080 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8081 unnecessary integer overflow. Check for size overflow.
8082 (encode_coding_object): Don't update size until xmalloc succeeds.
8084 * composite.c (get_composition_id): Check for overflow in glyph
8085 length calculations.
8087 Integer and memory overflow fixes for display code.
8088 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8089 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8090 (scrolling_window): Check for overflow in size calculations.
8091 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8092 Don't assume glyph table len fits in int.
8093 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8094 (row_table_size): Now ptrdiff_t, not int.
8095 (scrolling_window): Avoid overflow in size calculations.
8096 Don't update size until allocation succeeds.
8097 * fns.c (concat): Check for overflow in size calculations.
8098 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8099 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8100 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8102 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8103 (get_doc_string): Check for size calculation overflow.
8104 Don't update size until allocation succeeds.
8105 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8106 EMACS_INT, where ptrdiff_t will do.
8107 (Fsubstitute_command_keys): Check for string overflow.
8109 * editfns.c (set_time_zone_rule): Don't assume environment length
8111 (message_length): Now ptrdiff_t, not int.
8112 (Fmessage_box): Don't update size until allocation succeeds.
8113 Don't assume message length fits in int.
8114 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8116 * emacs.c (main): Do not reallocate argv, since there is a null at
8117 the end that can be overwritten, and this way there's no need to
8118 worry about size-calculation overflow.
8119 (sort_args): Check for size-calculation overflow.
8121 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8123 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8125 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8126 (x_set_scroll_bar_width, x_figure_window_size):
8127 Check for integer overflow.
8128 (x_set_alpha): Do not assume XINT fits in int.
8130 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8131 This is for the members text_lines, text_cols, total_lines, total_cols,
8132 where the system imposes an 'int' limit.
8134 * fringe.c (Fdefine_fringe_bitmap):
8135 Don't update size until alloc works.
8137 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8138 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8140 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8141 Check for size-calculation overflow.
8142 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8143 do, as we prefer signed integers.
8144 (id_to_widget.max_size, id_to_widget.used)
8145 (xg_store_widget_in_map, xg_remove_widget_from_map)
8146 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8147 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8148 Use and return ptrdiff_t, not int.
8149 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8150 * gtkutil.h: Change prototypes to match the above.
8152 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8153 are duplicate now that they've been promoted to lisp.h.
8154 (x_allocate_bitmap_record, x_alloc_image_color)
8155 (make_image_cache, cache_image, xpm_load):
8156 Don't update size until alloc is done.
8157 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8159 Check for size calculation overflow.
8160 (ct_colors_allocated_max): New constant.
8161 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
8164 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
8165 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
8166 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8167 Use ptrdiff_t, not int, to count maps.
8168 (read_char_minibuf_menu_prompt): Check for overflow in size
8169 calculations. Don't update size until allocation succeeds.
8170 Redo calculations to avoid overflow.
8171 * keyboard.h: Change prototypes to match the above.
8173 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
8175 (current_minor_maps): Check for size calculation overflow.

8196 * search.c (Freplace_match): Check for size calculation overflow.
8197 (Fset_match_data): Don't assume list lengths fit in 'int'.
8199 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8200 for command line length. Do not attempt to address one before the
8201 beginning of an array, as that's not portable.

8204 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8206 (encode_terminal_code, calculate_costs): Check for size
8207 calculation overflow.
8208 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
8209 table lengths and related sizes. Don't update size until alloc
8210 done. Redo calculations to avoid overflow.

8229 Use ptrdiff_t, not int, for sizes.
8230 (Finternal_make_lisp_face, cache_face):
8231 Check for size calculation overflow.
8232 (cache_face): Treat size calculation overflows as if they were
8233 memory exhaustion (the usual treatment), rather than aborting.
8235 * xfns.c (x_encode_text, x_set_name_internal)
8236 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8237 sizes, since they can exceed INT_MAX in size. Check for size
8238 calculation overflow.
8240 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8241 (xg_select): Check for size calculation overflow.
8242 Don't update size until alloc done.
8244 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8245 as sprintf is limited to int lengths.
8247 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8248 (X_LONG_MIN): New macros.
8249 Use them to make the following changes clearer.
8250 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8251 This change doesn't affect the value now, but it may help remind
8252 future maintainers not to raise the value too much later.
8253 (SELECTION_QUANTUM): Remove, replacing with ...
8254 (selection_quantum): ... new function, which avoids overflow.
8256 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8257 assumption that selection length fits in 'int'.
8258 (x_reply_selection_request, x_handle_selection_request)
8259 (x_get_window_property, receive_incremental_selection)

8265 Redo calculations to avoid overflow.
8266 (x_reply_selection_request): When sending hint, ceiling it at
8267 X_LONG_MAX rather than relying on wraparound overflow to send

8270 (lisp_data_to_selection_data, x_property_data_to_lisp):
8271 Check for size-calculation overflow.

8274 Don't store size until memory allocation succeeds.
8275 (x_get_window_property): Plug memory leak on memory exhaustion.
8276 Don't double-block input; malloc is safe here. Don't assume 2**34
8277 - 4 fits in unsigned long. Add an xassert to check
8278 XGetWindowProperty overflow. Be more careful about overflow
8279 calculations, and distinguish size from memory overflow better.
8280 (receive_incremental_selection): When tracing, don't assume
8281 unsigned int is less than INT_MAX.
8282 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8283 harmful) conversions of unsigned short to int.
8284 (lisp_data_to_selection_data): Don't assume that integers
8285 in the range -65535 through -1 fit in an X unsigned short.
8286 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8287 result parameters unless successful. Rely on cons_to_unsigned
8288 to report problems with elements; the old code wasn't right anyway.
8289 (x_check_property_data): Check for int overflow; we cannot use
8290 a wider type due to X limits.
8291 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8293 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

8323 * lisp.h (hash_lookup, hash_put):
8324 * minibuf.c (Ftest_completion):
8325 Use ptrdiff_t for hash table indexes, not int (which is too
8326 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8327 32-bit --with-wide-int hosts).
8329 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8330 Add a FIXME comment about memory leaks.

8359 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8360 (x_send_scroll_bar_event): Likewise. Check that the size does not
8361 exceed limits imposed by XClientMessageEvent, as well as the usual
8362 ptrdiff_t and size_t limits.
8364 * keyboard.c: Overflow, signedness and related fixes.
8365 (make_lispy_movement): Use same integer type in forward decl
8366 that is used in the definition.
8367 (read_key_sequence, keyremap_step):
8368 Change bufsize argument back to int, undoing my 2011-03-30 change.
8369 We prefer signed types, and int is wide enough here.
8370 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8371 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8372 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8373 length, not size_t. Use ptrdiff_t for index, not int.
8374 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8375 possibility of integer overflow.

8387 * xdisp.c (calc_pixel_width_or_height):
8388 * xfns.c (image_cache_refcount):
8389 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8390 on typical 64-bit hosts.

8398 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8399 (lookup_image): Remove unnecessary tests.

8401 since parse_image_check makes sure they fit into int.
8402 (png_load, gif_load, svg_load_image):
8403 Prefer int to unsigned where either will do.
8404 (tiff_handler): New function, combining the cores of the
8405 old tiff_error_handler and tiff_warning_handler.
8406 This function is rewritten to use vsnprintf and thereby avoid
8407 stack buffer overflows. It uses only the features of vsnprintf
8408 that are common to both POSIX and native Microsoft.
8409 (tiff_error_handler, tiff_warning_handler): Use it.
8410 (tiff_load, gif_load, imagemagick_load_image):
8411 Don't assume :index value fits in 'int'.
8412 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8413 (imagemagick_load_image): Check that crop parameters fit into
8414 the integer types that MagickCropImage accepts. Don't assume
8415 Vimagemagick_render_type has a nonnegative value. Don't assume
8416 size_t fits in 'long'.
8417 (gs_load): Use printmax_t to print the widest integers possible.

8430 handle_single_display_spec, not just 1 or zero.
8431 (handle_single_display_spec): If the display spec is of the form
8432 `(space ...)', and specifies display in the text area, return 2
8434 (try_cursor_movement): Check for the need to scroll more
8435 accurately, and prefer exact match for point under bidi.
8436 Don't advance `row' beyond the last row of the window.
8438 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8439 into disp_prop; all users changed.
8441 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8457 positioning on the newline at EOL of R2L text within L2R
8458 paragraph, and vice versa.
8459 (try_cursor_movement): Check continued rows, in addition to
8460 continuation rows. Fixes unwarranted scroll when point enters a
8461 continued line of R2L text within an L2R paragraph, or vice versa.
8462 (cursor_row_p): Consider the case of point being equal to
8463 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8464 from the end of a short line to the beginning of a continued line
8465 of R2L text within L2R paragraph.
8466 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8492 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8493 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8494 candidate is selected by the mouse, and that candidate has a
8495 composed character under the mouse.
8497 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8498 coordinates reported by pos-visible-in-window-p for a composed

8509 composed buffer positions.
8511 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8513 * image.c (gif_load): Don't assume that each subimage has the same
8514 dimensions as the base image. Handle disposal method that is
8515 "undefined" by the gif spec (Bug#9335).
8517 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8519 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8524 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8525 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8526 from an Org mode buffer to a Speedbar frame.
8528 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8529 a composition, take its buffer position from IT->cmp_it.charpos.
8530 Fixes cursor positioning at the beginning of a line that begins
8531 with a composed character.
8533 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8535 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8536 character bidirectional type, use STRONG_L instead. Fixes crashes
8537 in a buffer produced by `describe-categories'.
8539 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8540 members before the level stack, so they would be saved and
8541 restored when copying iterator state. Fixes incorrect reordering
8542 around TABs covered by display properties.
8544 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8630 the event loop. Get status from as_status (Bug#7276).
8632 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8633 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit

8643 (QCgnutls_bootprop_verify_hostname_error)
8644 (QCgnutls_bootprop_callbacks_verify): Rename from
8645 Qgnutls_bootprop_..., all uses changed.
8647 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8650 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8652 * xfaces.c (Qframe_set_background_mode): Now static.
8653 * dispextern.h (Qframe_set_background_mode): Remove decl.
8655 * process.c (Fnetwork_interface_info): Declare local only if needed.
8657 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8659 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8660 (Fnetwork_interface_list): Allocate in increments of bytes instead
8661 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8662 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8664 (struct ifflag_def): notrailers is smart on OSX.
8665 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8666 Get hardware address with getifaddrs if available.
8668 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8670 * xdisp.c (iterate_out_of_display_property): xassert that
8671 IT->position is set to within IT->object's boundaries. Break from
8672 the loop as soon as EOB is reached; avoids infloops in redisplay
8673 when IT->position is set up wrongly due to some bug.
8674 Set IT->current to match the bidi iterator unconditionally.
8675 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8676 entry. Force push_it to save on the stack the current
8677 buffer/string position, to be restored by pop_it. Fix flags in
8678 the iterator structure wrt the object coming from a display
8679 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8680 properties. (Bug#9284)
8682 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8684 * fontset.c (fontset_get_font_group): Add proper type checks.
8687 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

8690 and LC_VERSION_MIN_MACOSX.
8691 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8692 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8694 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8696 * xdisp.c (forward_to_next_line_start): Allow to use the
8697 no-display-properties-and-no-overlays under bidi display.
8698 Set disp_pos in the bidi iterator to avoid searches for display
8699 properties and overlays.
8701 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8703 * editfns.c (Fset_time_zone_rule): Document relationship with the
8706 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8707 the font entity extracted from the cache (Bug#8109).
8709 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8711 * composite.c (autocmp_chars): Don't reset point. That is done by
8712 restore_point_unwind (Bug#5984).
8714 2011-08-07 Juri Linkov <juri@jurta.org>
8716 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8717 to show the arg `TIME' instead of `TIMEVAL'.
8719 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8721 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8722 display property strides EOL and includes a newline, as in
8723 longlines-mode. (Bug#9254)
8724 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8725 word-wrap under bidirectional display. (Bug#9224)
8727 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8728 is non-zero, even if the data buffer is NULL. Fixes a crash in
8729 vertical-motion with longlines-mode. (Bug#9254)
8731 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8733 * bidi.c <bidi_cache_total_alloc>: Now static.
8734 (bidi_initialize): Initialize bidi_cache_total_alloc.
8736 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8739 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8740 amount allocated this far in `bidi_cache_total_alloc'.
8741 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8742 non-zero, only free the data buffer without restoring the cache
8743 contents. All callers changed.
8745 * dispextern.h (bidi_unshelve_cache): Update prototype.
8747 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8748 (move_it_in_display_line, move_it_to)
8749 (move_it_vertically_backward, move_it_by_lines): Replace the call
8750 to xfree to an equivalent call to bidi_unshelve_cache.
8751 (move_it_in_display_line_to): Fix logic of returning
8752 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8754 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8756 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8757 came from a string character with a `cursor' property. (Bug#9229)
8759 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8761 * Makefile.in (LIB_PTHREAD): New variable.
8762 (LIBES): Add LIB_PTHREAD (Bug#9216).
8764 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8765 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8767 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8769 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8771 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8773 * xterm.c (x_find_topmost_parent): New function.
8774 (x_set_frame_alpha): Find topmost parent window with
8775 x_find_topmost_parent and set the property there also (bug#9181).
8776 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8778 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8780 * callproc.c (Fcall_process): Avoid vfork clobbering
8781 the local vars buffer, coding_systems, current_dir.
8783 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8785 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8787 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8789 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8790 so that it is not optimized away.
8792 * xdisp.c (compute_display_string_pos): Remove unused local.
8794 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8796 Fix slow cursor motion and scrolling in large buffers with
8797 selective display, like Org Mode buffers. (Bug#9218)
8799 * dispextern.h (struct bidi_it): New member disp_prop_p.
8801 * xdisp.c: Remove one-slot cache of display string positions.
8802 (compute_display_string_pos): Accept an additional argument
8803 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8804 for a display string or property. If found, set DISP_PROP_P
8807 * bidi.c (bidi_fetch_char): Accept an additional argument
8808 DISP_PROP_P, and pass it to compute_display_string_pos.
8809 Only handle text covered by a display string if DISP_PROP_P is returned
8810 non-zero. All callers of bidi_fetch_char changed.
8812 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8814 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8816 2010-12-03 Don March <don@ohspite.net>
8818 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8819 last character M-[char] is translated to ESC [char] (bug#7541).
8821 2011-08-02 Kenichi Handa <handa@m17n.org>
8823 * lisp.h (uniprop_table): Extern it.
8825 * chartab.c (uniprop_table): Make it non-static.
8827 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8829 * xdisp.c (forward_to_next_line_start): Accept additional argument
8830 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8832 (reseat_at_next_visible_line_start): Use the bidi iterator state
8833 returned by forward_to_next_line_start to restore the state of
8834 it->bidi_it after backing up to previous newline. (Bug#9212)
8836 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8838 * regex.c (re_comp): Protoize.
8839 (re_exec): Fix return type.
8840 (regexec): Fix type of `ret'. (Bug#9203)
8842 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8844 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8845 This is needed if max-image-size is a floating-point number.
8847 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8849 * print.c (print_object): Print empty symbol as ##.
8851 * lread.c (read1): Read ## as empty symbol.
8853 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8855 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8856 setting frame foreground color (Bug#9175).
8857 (x_set_background_color): Likewise.
8859 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8860 contents (Bug#9176).
8861 (EmacsTooltip -init): Remove bezels and add shadows to
8864 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8865 or scroll bar (Bug#8470).
8867 * nsfont.m (nsfont_open): Remove assignment to voffset and
8868 unnecessary vars hshink, expand, hd, full_height, min_height.
8869 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8871 * nsterm.h (nsfont_info): Remove voffset field.
8873 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8875 Implement strike-through and overline on NextStep (Bug#8863).
8877 * nsfont.m (nsfont_open): Use underline position provided by font,
8878 instead of hard-coded value of 2.
8879 (nsfont_draw): Call ns_draw_text_decoration instead.
8881 * nsterm.h: Add declaration for ns_draw_text_decoration.
8883 * nsterm.m (ns_draw_text_decoration): New function for drawing
8884 underline, overline, and strike-through.
8885 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8886 ns_draw_text_decoration. Change treatment of cursor drawing to
8887 accommodate underlining, etc.
8889 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8891 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8894 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8896 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8897 Without this fix, if a signal arrives just after memory fills up,
8898 'malloc' might be invoked reentrantly.
8900 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8901 In other words, assume that every image size is allowed, on non-X
8902 hosts. This assumption is probably wrong, but it lets Emacs compile.
8904 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8906 * regex.c (re_iswctype): Convert return values to boolean.
8908 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8910 * xdisp.c (compute_display_string_pos): Don't use cached display
8911 string position if the buffer had its restriction changed.
8914 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8916 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8918 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8920 Integer signedness and overflow and related fixes. (Bug#9079)
8922 * bidi.c: Integer size and overflow fixes.
8923 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8924 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8925 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8926 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8927 (bidi_find_other_level_edge):
8928 Use ptrdiff_t instead of EMACS_INT where either will do.
8929 This works better on 32-bit hosts configured --with-wide-int.
8930 (bidi_cache_ensure_space): Check for size-calculation overflow.
8931 Use % rather than repeated addition, for better worst-case speed.
8932 Don't set bidi_cache_size until after xrealloc returns, because it
8934 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8935 (bidi_cache_ensure_space): Also check that the bidi cache size
8936 does not exceed that of the largest Lisp string or buffer. See Eli
8937 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8939 * alloc.c (__malloc_size_t): Remove.
8940 All uses replaced by size_t. See Andreas Schwab's note
8941 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8943 * image.c: Improve checking for integer overflow.
8944 (check_image_size): Assume that f is nonnull, since
8945 it is always nonnull in practice. This is one less thing to
8946 worry about when checking for integer overflow later.
8947 (x_check_image_size): New function, which checks for integer
8948 overflow issues inside X.
8949 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8950 This removes the need for a memory_full check.
8951 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8952 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8953 (xbm_read_bitmap_data): Change locals back to 'int', since
8954 their values must fit in 'int'.
8955 (xpm_load_image, png_load, tiff_load):
8956 Invoke x_create_x_image_and_pixmap earlier,
8957 to avoid much needless work if the image is too large.
8958 (tiff_load): Treat overly large images as if
8959 x_create_x_image_and_pixmap failed, not as malloc failures.
8960 (gs_load): Use x_check_image_size.
8962 * gtkutil.c: Omit integer casts.
8963 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8964 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8966 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8968 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8969 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8970 would wrongly return t on a 64-bit host.
8972 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8973 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8974 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8975 and therefore cause GCC to emit a bogus diagnostic in some cases.
8977 * image.c: Integer signedness and overflow and related fixes.
8978 This is not an exhaustive set of fixes, but it's time to
8979 record what I've got.
8980 (lookup_pixel_color, check_image_size): Remove redundant decls.
8981 (check_image_size): Don't assume that arbitrary EMACS_INT values
8982 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8983 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8984 (tiff_load, imagemagick_load_image):
8985 Check for overflow in size calculations.
8986 (x_create_x_image_and_pixmap): Remove unnecessary test for
8987 xmalloc returning NULL; that can't happen.
8988 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8989 (xpm_color_bucket): Use better integer hashing function.
8990 (xpm_cache_color): Don't possibly over-allocate memory.
8991 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8992 (gif_memory_source):
8993 Use ptrdiff_t, not int or size_t, to record sizes.
8994 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8995 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8996 either works, as we prefer signed integers.
8997 (tiff_read_from_memory, tiff_write_from_memory):
8998 Return tsize_t, not size_t, since that's what the TIFF API wants.
8999 (tiff_read_from_memory): Don't fail simply because the read would
9000 go past EOF; instead, return a short read.
9001 (tiff_load): Omit no-longer-needed casts.
9002 (Fimagemagick_types): Don't assume size fits into 'int'.
9004 Improve hashing quality when configured --with-wide-int.
9005 * fns.c (hash_string): New function, taken from sxhash_string.
9006 Do not discard information about ASCII character case; this
9007 discarding is no longer needed.
9008 (sxhash-string): Use it. Change sig to match it. Caller changed.
9009 * lisp.h: Declare it.
9010 * lread.c (hash_string): Remove, since we now use fns.c's version.
9011 The fns.c version returns a wider integer if --with-wide-int is
9012 specified, so this should help the quality of the hashing a bit.
9014 * emacs.c: Integer overflow minor fix.
9015 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9016 Define only if GNU_LINUX.
9017 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9019 * dispnew.c: Integer signedness and overflow fixes.
9020 Remove unnecessary forward decls, that were a maintenance hassle.
9021 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9023 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9024 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9025 (prepare_desired_row, line_draw_cost):
9026 Use int, not unsigned, where either works.
9027 (save_current_matrix, restore_current_matrix):
9028 Use ptrdiff_t, not size_t, where either works.
9029 (init_display): Check for overflow more accurately, and without
9030 relying on undefined behavior.
9032 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9033 Remove, replacing with the new symbols in lisp.h. All uses changed.
9034 * fileio.c (make_temp_name):
9035 * filelock.c (lock_file_1, lock_file):
9036 * xdisp.c (message_dolog):
9037 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9038 Use pMd etc. instead.
9039 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9040 replacing the pWIDE etc. symbols removed from editfns.c.
9042 * keyboard.h (num_input_events): Now uintmax_t.
9043 This is (very slightly) less likely to mess up due to wraparound.
9046 * buffer.c: Integer signedness fixes.
9047 (alloc_buffer_text, enlarge_buffer_text):
9048 Use ptrdiff_t rather than size_t when either will do, as we prefer
9051 * alloc.c: Integer signedness and overflow fixes.
9052 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9053 (__malloc_size_t): Default to size_t, not to int.
9054 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9055 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9056 Prefer ptrdiff_t to size_t when either would do, as we prefer
9058 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9059 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9060 Now const. Initialize with values that are in range even if char
9062 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9063 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9064 These functions do the right thing with sizes > 2**32.
9065 (check_depth): Now ptrdiff_t, not int.
9066 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9067 Adjust to new way of storing sizes. Check for size overflow bugs
9069 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9070 slightly wrong anyway, as it missed one instance of
9071 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9072 (refill_memory_reserve): Omit needless cast to size_t.
9073 (mark_object_loop_halt): Mark as externally visible.
9075 * xselect.c: Integer signedness and overflow fixes.
9076 (Fx_register_dnd_atom, x_handle_dnd_message):
9077 Use ptrdiff_t, not size_t, since we prefer signed.
9078 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9079 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9080 x_dnd_atoms_size and x_dnd_atoms_length.
9082 * doprnt.c: Prefer signed to unsigned when either works.
9084 * doprnt.c (doprnt):
9086 * xdisp.c (vmessage):
9087 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9088 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9089 prefer signed arithmetic to avoid comparison confusion.
9090 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9091 but is a bit tricky.
9093 Assume freestanding C89 headers, string.h, stdlib.h.
9094 * data.c, doprnt.c, floatfns.c, print.c:
9095 Include float.h unconditionally.
9096 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9097 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9098 * regex.c: Likewise for stddef.h, string.h.
9099 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9100 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9101 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9102 (STDC_HEADERS): Remove obsolete defines.
9103 * sysdep.c: Include limits.h unconditionally.
9105 Assume support for memcmp, memcpy, memmove, memset.
9106 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9107 * regex.c (memcmp, memcpy):
9108 Remove; we assume C89 now.
9110 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9111 (__malloc_safe_bcopy): Remove; no longer needed.
9113 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9114 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9115 well either way, and we prefer signed to unsigned.
9117 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9119 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9120 closes the connection while we're reading (bug#9182).
9122 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9124 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9125 are specified (Bug#9168).
9127 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9129 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9130 Found by GCC static checking and --with-wide-int on a 32-bit host.
9132 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9134 * xdisp.c (compute_display_string_pos): Fix logic of caching
9135 previous display string position. Initialize cached_prev_pos to
9136 -1. Fixes slow-down at the beginning of a buffer.
9138 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9140 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9141 for attrs[LFACE_FONTSET_INDEX].
9143 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9145 * xml.c (parse_region): Remove unused local
9146 that was recently introduced.
9148 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9150 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9151 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9153 * xdisp.c (move_it_in_display_line_to): Record the best matching
9154 position for TO_CHARPOS while scanning the line, and restore it on
9155 exit if none of the characters scanned was an exact match.
9156 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9157 when exact match is impossible due to invisible text, and the
9158 lines are truncated.
9160 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9162 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask

9167 Fix a significant slow-down of cursor motion with C-n, C-p,
9168 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9169 auto-repeat under bidi redisplay in fontified buffers.
9170 * xdisp.c (compute_stop_pos_backwards): New function.
9171 (next_element_from_buffer): Call compute_stop_pos_backwards to
9172 find a suitable prev_stop when we find ourselves before
9174 (reseat): Don't look for prev_stop, as that could mean a very long
9176 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9177 <cached_disp_overlay_modiff>: Cache for last found display string
9179 (compute_display_string_pos): Return the cached position if asked
9180 about the same buffer in the same area of character positions, and
9181 the buffer wasn't changed since the time the display string
9182 position was cached.
9184 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9186 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9187 is an integer, which is important for empty lines. (Bug#9149)
9189 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9191 * frame.c (Fmodify_frame_parameters): In tty case, update the
9192 default face if necessary (Bug#4238).
9194 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9196 * editfns.c (Fstring_to_char): No need to explain what a character
9197 is in the docstring (Bug#6576).
9199 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9201 * xml.c (parse_region): Make sure we always return a tree.
9203 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9205 * xml.c (parse_region): If a document contains only comments,
9208 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9210 * xml.c (make_dom): Return comments, too.
9212 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9215 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9216 and the surrounding thread.
9217 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9218 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9219 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9221 * s/openbsd.h (BROKEN_SIGIO): Define.
9222 * unexelf.c (unexec) [__OpenBSD__]:
9223 Don't update the .mdebug section of the Alpha COFF symbol table.
9225 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9227 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9230 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9232 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9233 This fixes some race conditions on the permissions of any newly
9236 * alloc.c (valid_pointer_p): Use pipe, not open.
9237 This fixes some permissions issues when debugging.
9239 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9240 If fchown fails to set both uid and gid, try to set just gid,
9241 as that is sometimes allowed. Adjust the file's mode to eliminate
9242 setuid or setgid bits that are inappropriate if fchown fails.
9244 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9246 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9247 to compare Lisp_Objects.

9258 symbol character follows.
9260 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9262 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9263 This works around a problem with the previous change to Fcopy_file.
9264 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9265 and without this change, GCC might complain about discarding
9266 fchown's return value.
9268 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9270 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9272 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9274 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9276 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9278 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9279 it's used from the C level.
9281 * process.c: Use the same condition for POLL_FOR_INPUT in both
9282 keyboard.c and process.c (bug#1858).
9284 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9287 (Fgnutls_boot): Use it.
9289 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9291 * doc.c (Fsubstitute_command_keys): Revert last change.
9293 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9295 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9296 quotes the next character, and doesn't affect other longer
9297 sequences (bug#8935).
9299 * lread.c (syms_of_lread): Clarify that is isn't only
9300 `eval-buffer' and `eval-defun' that's affected by
9301 `lexical-binding' (bug#8460).
9303 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9305 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9306 bidi redisplay when a line includes both an image and is truncated.

9310 Fix minor problems found by static checking.
9311 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9312 (elsz): Now a signed constant, not a size_t var. We prefer signed
9313 types to unsigned, to avoid integer comparison confusion. Without
9314 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9315 "cannot optimize loop, the loop counter may overflow", a symptom
9317 * indent.c (Fvertical_motion): Mark locals as initialized.
9318 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9320 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9322 * search.c (Fre_search_backward): Mention `case-fold-search' in
9323 all the re_search_* functions (bug#8138).

9341 Initialize itb.string.lstring.
9342 (init_iterator): Call bidi_init_it only of a valid
9343 buffer position was specified. Initialize paragraph_embedding to
9345 (reseat_to_string): Initialize the bidi iterator.
9346 (display_string): If we need to ignore text properties of
9347 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

9352 (compute_display_string_end): Support display properties on Lisp
9354 (init_iterator, reseat_1, reseat_to_string): Initialize the
9355 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9356 when iterating on a string not from display properties).
9357 (compute_display_string_pos, compute_display_string_end):
9358 Fix calculation of the object to scan. Fixes an error when using
9360 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9361 base_level_stop; instead, set base_level_stop to BEGV.
9362 Fixes crashes in vertical-motion.
9363 (next_element_from_buffer): Improve commentary for when
9364 the iterator is before prev_stop.
9365 (init_iterator): Initialize bidi_p from the default value of
9366 bidi-display-reordering, not from buffer-local value. Use the
9367 buffer-local value only if initializing for buffer iteration.
9368 (handle_invisible_prop): Support invisible properties on strings
9369 that are being bidi-reordered.
9370 (set_iterator_to_next): Support bidi reordering of C strings and
9372 (next_element_from_string): Support bidi reordering of Lisp
9374 (handle_stop_backwards): Support Lisp strings as well.

9380 (next_element_from_string, next_element_from_c_string)
9381 (next_element_from_buffer): Add xassert's for correspondence
9382 between IT's object being iterated and it->bidi_it.string

9388 parts of next_element_from_buffer, next_element_from_string, and
9389 next_element_from_c_string.
9390 (tool_bar_lines_needed, redisplay_tool_bar)
9391 (display_menu_bar): Force left-to-right direction. Add a FIXME
9392 comment for making that be controlled by a user option.

9402 iterator for displaying display or overlay strings.
9403 (forward_to_next_line_start): Don't use the shortcut if
9405 (back_to_previous_visible_line_start): If handle_display_prop
9406 pushed the iterator stack, restore the internal state of the bidi
9407 iterator by calling bidi_pop_it same number of times.
9408 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9409 and we are bidi-iterating, don't decrement the iterator position;
9410 instead, set the first_elt flag in the bidi iterator, to produce
9412 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9413 (push_display_prop): xassert that we are iterating a buffer.
9414 (push_it, pop_it): Save and restore paragraph_embedding member.

9418 correctly. Don't assume unibyte strings are not bidi-reordered.
9419 (compute_display_string_pos)
9420 (compute_display_string_end): Fix handling the case of C string.
9421 (push_it, pop_it): Save and restore from_disp_prop_p.
9422 (handle_single_display_spec, push_display_prop): Set the
9423 from_disp_prop_p flag.
9424 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9471 (bidi_move_to_visually_next): Compare cache index with
9472 bidi_cache_start rather than with zero.
9473 (bidi_fetch_char): Accept new argument STRING; all callers
9474 changed. Support iteration over a string. Support strings with
9475 display properties. Support unibyte strings. Fix the type of
9476 `len' according to what STRING_CHAR_AND_LENGTH expects.
9477 (bidi_paragraph_init, bidi_resolve_explicit_1)

9884 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9885 subseconds part to the entropy, as that's a bit more random.
9886 Prefer signed to unsigned, since the signedness doesn't matter and
9887 in general we prefer signed. When given a limit, use a
9888 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9889 latter isn't right if USE_2_TAGS_FOR_INTS.

9934 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

10031 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
10034 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
10036 * eval.c (struct backtrace): Simplify and port the data structure.
10037 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10038 signed bit field, as this assumption is not portable and it makes
10039 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10040 "char debug_on_exit : 1" as this is not portable either; instead,
10041 use the portable "unsigned int debug_on_exit : 1". Remove unused
10042 member evalargs. Remove obsolete comments about cc bombing out.
10044 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

10112 (emacs_fixed_new): Set priv->f to argument.
10113 (emacs_fixed_get_preferred_width)
10114 (emacs_fixed_get_preferred_height): Use min_width/height from
10115 frames size_hint to set minimum and natural (Bug#8919).
10116 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10117 and use min_width/height from frames size_hint to set
10118 min_width/height (Bug#8919).

10138 Use gnulib's dup2 module instead of rolling our own.
10139 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

10206 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10208 Integer and buffer overflow fixes (Bug#8873).
10210 * print.c (printchar, strout): Check for string overflow.
10211 (PRINTPREPARE, printchar, strout):
10212 Don't set size unless allocation succeeds.
10214 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10215 for sizes. Check for string overflow more accurately.
10216 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10218 * macros.c: Integer and buffer overflow fixes.
10219 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10220 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10224 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10226 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10228 * lread.c: Integer overflow fixes.
10229 (read_integer): Radix is now EMACS_INT, not int,
10230 to improve quality of diagnostics for out-of-range radices.
10231 Calculate buffer size correctly for out-of-range radices.
10232 (read1): Check for integer overflow in radices, and in
10233 read-circle numbers.
10234 (read_escape): Avoid int overflow.
10235 (Fload, openp, read_buffer_size, read1)
10236 (substitute_object_recurse, read_vector, read_list, map_obarray):
10237 Use ptrdiff_t, not int, for sizes.

10252 2011-06-22 Leo Liu <sdl.web@gmail.com>
10254 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10255 Move to minibuffer.el.
10257 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10259 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10260 The following patches are for when GLYPH_DEBUG && !XASSERT.
10261 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10262 * dispnew.c (flush_stdout):
10263 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10264 Mark as externally visible.
10265 * dispnew.c (check_window_matrix_pointers): Now static.
10266 * dispnew.c (window_to_frame_vpos):
10267 * xfns.c (unwind_create_frame):
10268 * xterm.c (x_check_font): Remove unused local.
10269 * scroll.c (CHECK_BOUNDS):
10270 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10271 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10272 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10273 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10274 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10276 (debug_method_add): Use va_list and vsprintf rather than relying
10277 on undefined behavior with wrong number of arguments.
10278 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10279 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10280 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10281 since we're not interested in debugging glyphs with old libraries.
10282 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10283 GCC 4.6.0's static checking.
10285 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10287 Integer overflow and signedness fixes (Bug#8873).

10299 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10301 * xfaces.c (load_pixmap):
10302 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10303 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10304 (.bitmaps_last, struct x_output.icon_bitmap):
10305 Use ptrdiff_t, not int, for bitmap indexes.
10306 (x_allocate_bitmap_record): Check for size overflow.
10307 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10309 Use ptrdiff_t, not int, for overlay counts.
10310 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10311 * editfns.c (overlays_around, get_pos_property):
10312 * textprop.c (get_char_property_and_overlay):
10313 * xdisp.c (next_overlay_change, note_mouse_highlight):
10314 * xfaces.c (face_at_buffer_position):
10315 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10316 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10317 (Fnext_overlay_change, Fprevious_overlay_change)
10318 (mouse_face_overlay_overlaps, Foverlays_in):
10319 Use ptrdiff_t, not int, for sizes.
10320 (overlays_at, overlays_in): Check for size-calculation overflow.
10322 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10324 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10325 (x_session_initialize): Do not assume string length fits in int.
10327 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10328 This is unlikely, but can occur if DPI is outlandish.
10330 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10331 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10333 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10334 * xrdb.c (magic_file_p, search_magic_path):
10335 Omit last arg SUFFIX; it was always 0. All callers changed.
10336 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10338 * xfont.c (xfont_match): Avoid need for strlen.
10340 * xfns.c: Don't assume strlen fits in int.

10343 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10344 not unsigned long, as we prefer signed integers. All callers changed.
10345 Detect integer overflow in repeat count.
10346 (message_dolog): Don't assume print length fits in 39 bytes.
10347 (display_mode_element): Don't assume strlen fits in int.
10349 * termcap.c: Don't assume sizes fit in int and never overflow.
10350 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10351 (gobble_line): Check for size-calculation overflow.
10353 * minibuf.c (Fread_buffer):
10354 * lread.c (intern, intern_c_string):
10355 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10356 Don't assume string length fits in int.

10365 Don't assume integer property fits in fixnum.
10366 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10368 * filelock.c: Fix some buffer overrun and integer overflow issues.
10369 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10370 Reformulate so as not to need the command string.
10371 Invoke gzip -cd rather than gunzip, as it's more portable.
10372 (lock_info_type, lock_file_1, lock_file):
10373 Don't assume pid_t and time_t fit in unsigned long.
10374 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10375 (current_lock_owner): Prefer signed type for sizes.
10376 Use memcpy, not strncpy, where memcpy is what is really wanted.
10377 Don't assume (via atoi) that time_t and pid_t fit in int.
10378 Check for time_t and/or pid_t out of range, e.g., via a network share.
10379 Don't alloca where an auto var works fine.
10381 * fileio.c: Fix some integer overflow issues.
10382 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10383 Don't assume string length fits in int.
10384 (directory_file_name): Don't assume string length fits in long.
10385 (make_temp_name): Don't assume pid fits in int, or that its print
10386 length is less than 20.
10388 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10390 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10392 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10394 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10395 We prefer signed integers, even for size calculations.
10397 * emacs.c: Don't assume string length fits in 'int'.
10398 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10399 (main): Don't invoke strlen when not needed.

10404 * callproc.c (getenv_internal_1, getenv_internal)
10405 (Fgetenv_internal):
10406 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10408 * lread.c (invalid_syntax): Omit length argument.
10409 All uses changed. This doesn't fix a bug, but it simplifies the
10410 code away from its former Hollerith-constant appearance, and it's
10411 one less 'int' to worry about when looking at integer-overflow issues.
10412 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10414 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10415 This didn't break anything, but it didn't help either.
10416 It's confusing to put a bogus integer in a place where the actual
10417 value does not matter.
10418 (LIST_END_P): Remove unused macro and its bogus comment.
10419 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10421 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10422 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10424 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10425 We prefer signed types, and the value cannot exceed the EMACS_INT
10426 range anyway (because otherwise the length would not be representable).
10427 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10428 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10429 This avoids a GCC warning when WIDE_EMACS_INT.
10431 * indent.c (sane_tab_width): New function.
10432 (current_column, scan_for_column, Findent_to, position_indentation)
10433 (compute_motion): Use it. This is just for clarity.
10434 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10436 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10438 * lisp.h (lint_assume): New macro.
10439 * composite.c (composition_gstring_put_cache):
10440 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10442 * editfns.c, insdel.c:
10443 Omit unnecessary forward decls, to simplify future changes.
10445 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10447 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10449 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10450 Use much-faster test for byte-length change.
10451 Don't assume string byte-length fits in 'int'.
10452 Check that character arg fits in 'int'.
10453 (mapcar1): Declare byte as byte, for clarity.
10455 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10457 * fns.c (concat): Catch string overflow earlier.
10458 Do not rely on integer wraparound.
10460 * dispextern.h (struct it.overlay_strings_charpos)
10461 (struct it.selective): Now EMACS_INT, not int.
10462 * xdisp.c (forward_to_next_line_start)
10463 (back_to_previous_visible_line_start)
10464 (reseat_at_next_visible_line_start, next_element_from_buffer):
10465 Don't arbitrarily truncate the value of 'selective' to int.
10467 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10469 * composite.c: Don't truncate sizes to 'int'.
10470 (composition_gstring_p, composition_reseat_it)
10471 (composition_adjust_point): Use EMACS_INT, not int.
10472 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10473 not EMACS_UINT, for indexes.
10475 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10477 * buffer.c: Include <verify.h>.
10478 (struct sortvec.priority, struct sortstr.priority):
10479 Now EMACS_INT, not int.
10480 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10481 (struct sortstr.size, record_overlay_string)
10482 (struct sortstrlist.size, struct sortlist.used):
10483 Don't truncate size to int.
10484 (record_overlay_string): Check for size-calculation overflow.
10485 (init_buffer_once): Check at compile-time, not run-time.
10487 2011-06-22 Jim Meyering <meyering@redhat.com>
10489 Don't leak an XBM-image-sized buffer
10490 * image.c (xbm_load): Free the image buffer after using it.
10492 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10495 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10496 that Sun C diagnosed.
10497 * fns.c (secure_hash): Fix pointer signedness issue.
10498 * intervals.c (static_offset_intervals): New function.
10499 (offset_intervals): Use it.
10501 2011-06-21 Leo Liu <sdl.web@gmail.com>
10504 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10507 * fns.c (secure_hash): Rename from crypto_hash_function and change
10508 the first arg to accept symbols.
10509 (Fsecure_hash): New primitive.
10510 (syms_of_fns): New symbols.
10512 2011-06-20 Deniz Dogan <deniz@dogan.se>
10514 * process.c (Fset_process_buffer): Clarify return value in
10517 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10519 * dispnew.c (add_window_display_history): Use BVAR.
10521 * xdisp.c (debug_method_add): Use BVAR.
10522 (check_window_end, dump_glyph_matrix, dump_glyph)
10523 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10525 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10528 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10529 check till after the cache is created in init_frame_faces.
10531 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10533 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10535 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10537 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10538 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10539 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10541 Improve buffer-overflow checking (Bug#8873).
10542 * fileio.c (Finsert_file_contents):
10543 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10544 Remove the old (too-loose) buffer overflow checks.
10545 They weren't needed, since make_gap checks for buffer overflow.
10546 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10547 The old code merely checked for Emacs fixnum overflow, and relied
10548 on undefined (wraparound) behavior. The new code avoids undefined
10549 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10551 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10552 Tune. Don't use wider integers than needed. Don't use alloca.
10553 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10555 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10557 * insdel.c, lisp.h (buffer_overflow): New function.
10558 (insert_from_buffer_1, replace_range, replace_range_2):
10559 * insdel.c (make_gap_larger):
10560 * editfns.c (Finsert_char):
10561 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10563 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10565 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10567 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10569 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10570 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10572 * fileio.c: Don't assume EMACS_INT fits in off_t.
10573 (emacs_lseek): New static function.
10574 (Finsert_file_contents, Fwrite_region): Use it.
10575 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10577 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10579 * fns.c: Don't overflow int when computing a list length.
10580 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10581 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10582 truncation on 64-bit hosts. Check for QUIT every
10583 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10584 faster and is responsive enough.
10585 (Flength): Report an error instead of overflowing an integer.
10586 (Fsafe_length): Return a float if the value is not representable
10587 as a fixnum. This shouldn't happen except in contrived situations.
10588 (Fnthcdr, Fsort): Don't assume list length fits in int.
10589 (Fcopy_sequence): Don't assume vector length fits in int.
10591 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10592 (header_size, word_size): New constants.
10593 (allocate_vectorlike): Don't check size overflow here.
10594 (allocate_vector): Check it here instead, since this is the only
10595 caller of allocate_vectorlike that could cause overflow.
10596 Check that the new vector's length is representable as a fixnum.
10598 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10599 The previous code was bogus. For example, next_almost_prime (32)
10600 returned 39, which is undesirable as it is a multiple of 3; and
10601 next_almost_prime (24) returned 25, which is a multiple of 5 so
10602 why was the code bothering to check for multiples of 7?
10604 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10606 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10608 Variadic C functions now count arguments with ptrdiff_t.
10609 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10610 Back then I didn't know that the Emacs coding style prefers signed int.
10611 Also, in the meantime I found a few more instances where arguments
10612 were being counted with int, which may truncate counts on 64-bit
10613 machines, or EMACS_INT, which may be unnecessarily wide.
10614 * lisp.h (struct Lisp_Subr.function.aMANY)
10615 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10616 Arg counts are now ptrdiff_t, not size_t.
10617 All variadic functions and their callers changed accordingly.
10618 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10619 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10620 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10621 * callint.c (Fcall_interactively): Check arg count for overflow,
10622 to avoid potential buffer overrun. Use signed char, not 'int',
10623 for 'varies' array, so that we needn't bother to check its size
10624 calculation for overflow.
10625 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10626 * eval.c (apply_lambda):
10627 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10628 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10629 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10631 * callint.c (Fcall_interactively): Don't use index var as event count.
10633 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10634 * mem-limits.h (SIZE): Remove; no longer used.
10636 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10638 Remove unnecessary casts.
10639 * xterm.c (x_term_init):
10640 * xfns.c (x_set_border_pixel):
10641 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10642 These aren't needed now that we assume ANSI C.
10644 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10645 It's more likely to cause problems (due to unsigned overflow)
10648 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10650 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10652 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10654 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10656 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10658 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10660 GLYPH_CODE_FACE returns EMACS_INT, not int.
10661 * dispextern.h (merge_faces):
10662 * xfaces.c (merge_faces):
10663 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10664 Don't assume EMACS_INT fits in int.
10666 * character.h (CHAR_VALID_P): Remove unused parameter.
10667 * fontset.c, lisp.h, xdisp.c: All uses changed.
10669 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10671 * fns.c (concat): Minor tuning based on overflow analysis.
10672 This doesn't fix any bugs. Use int to hold character, instead
10673 of constantly refetching from Emacs object. Use XFASTINT, not
10674 XINT, for value known to be a character. Don't bother comparing
10675 a single byte to 0400, as it's always less.
10677 * floatfns.c (Fexpt):
10678 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10680 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10683 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10685 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10686 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10687 incorrectly succeed when S was a string, because 4294967386 was
10688 truncated before it was used.
10690 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10691 Otherwise, an out-of-range integer could cause undefined behavior
10694 * composite.c: Use int, not EMACS_INT, for characters.
10695 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10696 EMACS_INT, for values that are known to be in character range.
10697 This doesn't fix any bugs but is the usual style inside Emacs and
10698 may generate better code on 32-bit machines.
10700 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10701 This is for reasons similar to the recent CHAR_STRING fix.
10702 * charset.c (Fencode_char): Check that character arg is actually
10703 a character. Pass an int to ENCODE_CHAR.
10704 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10705 wider than 'int', as a compile-time check to prevent future regressions
10708 * character.c (char_string): Remove unnecessary casts.
10710 Make sure a 64-bit char is never passed to CHAR_STRING.
10711 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10712 by silently ignoring the top 32 bits, allowing some values
10713 that were far too large to be valid characters.
10714 * character.h: Include <verify.h>.
10715 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10716 arguments are no wider than unsigned, as a compile-time check
10717 to prevent future regressions in this area.
10719 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10720 (Fsubst_char_in_region):
10722 * xdisp.c (decode_mode_spec_coding):
10723 Adjust to CHAR_STRING's new requirement.
10724 * editfns.c (Finsert_char, Fsubst_char_in_region):
10725 * fns.c (concat): Check that character args are actually
10726 characters. Without this test, these functions did the wrong
10727 thing with wildly out-of-range values on 64-bit hosts.
10729 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10730 These casts should not be needed on 32-bit hosts, either.
10731 * keyboard.c (read_char):
10732 * lread.c (Fload): Remove casts to unsigned.
10734 * lisp.h (UNSIGNED_CMP): New macro.
10735 This fixes comparison bugs on 64-bit hosts.
10736 (ASCII_CHAR_P): Use it.
10737 * casefiddle.c (casify_object):
10738 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10739 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10740 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10741 * dispextern.h (FACE_FROM_ID):
10742 * keyboard.c (read_char): Use UNSIGNED_CMP.
10744 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10745 not to EMACS_INT, to avoid GCC warning.
10747 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10749 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10750 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10751 isn't needed on 32-bit machines.
10753 * buffer.c (Fgenerate_new_buffer_name):
10754 Use EMACS_INT for count, not int.
10755 (advance_to_char_boundary): Return EMACS_INT, not int.
10757 * data.c (Qcompiled_function): Now static.
10759 * window.c (window_body_lines): Now static.
10761 * image.c (gif_load): Rename local to avoid shadowing.
10763 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10764 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10765 * alloc.c (make_save_value): Integer argument is now of type
10766 ptrdiff_t, not int.
10767 (mark_object): Use ptrdiff_t, not int.
10768 * lisp.h (pD): New macro.
10769 * print.c (print_object): Use it.
10771 * alloc.c: Use EMACS_INT, not int, to count objects.
10772 (total_conses, total_markers, total_symbols, total_vector_size)
10773 (total_free_conses, total_free_markers, total_free_symbols)
10774 (total_free_floats, total_floats, total_free_intervals)
10775 (total_intervals, total_strings, total_free_strings):
10776 Now EMACS_INT, not int. All uses changed.
10777 (Fgarbage_collect): Compute overall total using a double, so that
10778 integer overflow is less likely to be a problem. Check for overflow
10779 when converting back to an integer.
10780 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10781 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10782 These were 'int' variables that could overflow on 64-bit hosts;
10783 they were never used, so remove them instead of repairing them.
10784 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10785 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10786 Previously, this ceilinged at INT_MAX, but that doesn't work on
10788 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10790 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10791 (allocate_vectorlike): Check for ptrdiff_t overflow.
10792 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10793 when a (possibly-narrower) signed value would do just as well.
10794 We prefer using signed arithmetic, to avoid comparison confusion.
10796 * alloc.c: Catch some string size overflows that we were missing.
10797 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10798 for convenience in STRING_BYTES_MAX.
10799 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10800 The definition here is exact; the one in lisp.h was approximate.
10801 (allocate_string_data): Check for string overflow. This catches
10802 some instances we weren't catching before. Also, it catches
10803 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10804 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10805 and ptrdiff_t and EMACS_INT are both 64 bits.
10807 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10808 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10809 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10811 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10813 * alloc.c (Fmake_string): Check for out-of-range init.
10815 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10817 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10819 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10821 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10822 xg_get_default_scrollbar_width.
10824 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10825 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10826 (style_changed_cb): Call update_theme_scrollbar_width and call
10827 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10828 all frames (Bug#8505).
10829 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10830 Call gtk_window_set_resizable if HAVE_GTK3.
10831 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10832 and height if HAVE_GTK3 (Bug#8505).
10833 (scroll_bar_width_for_theme): New variable.
10834 (update_theme_scrollbar_width): New function.
10835 (xg_get_default_scrollbar_width): Move code to
10836 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10837 (xg_initialize): Call update_theme_scrollbar_width.
10839 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10841 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10843 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10845 * frame.c (make_frame): Call other_buffer_safely instead of
10848 * window.c (temp_output_buffer_show): Call display_buffer with
10849 second argument Vtemp_buffer_show_specifiers and reset latter
10850 immediately after the call.
10851 (Vtemp_buffer_show_specifiers): New variable.
10852 (auto_window_vscroll_p, next_screen_context_lines)
10853 (Vscroll_preserve_screen_position): Remove leading asterisks from
10856 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10858 Fix minor problems found by GCC 4.6.0 static checking.
10859 * buffer.c (Qclone_number): Remove for now, as it's unused.
10860 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10861 (record_buffer): Remove unused local.
10862 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10863 (set_frame_buffer_list): Remove; unused.
10864 * frame.h (other_visible_frames): Remove decl.
10865 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10866 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10867 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10869 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10870 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10871 Define only if HAVE_GPM.
10872 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10873 (update_hints_inhibit): Remove; never set. All uses removed.
10874 * widgetprv.h (emacsFrameClassRec): Remove decl.
10875 * window.c (delete_deletable_window): Now returns void, since it
10876 wasn't returning anything.
10877 (compare_window_configurations): Remove unused locals.
10878 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10879 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10880 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10881 the same widths as pointers. This follows up on the 2011-05-06 patch.
10882 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10883 * xterm.h: Likewise.
10884 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10886 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
10888 * makefile.w32-in: Update dependencies.
10889 (LISP_H): Add lib/intprops.h.
10891 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10893 * image.c (gif_load): Add animation frame delay to the metadata.

11349 Obey Vx_select_enable_clipboard_manager. Catch errors in
11350 x_clipboard_manager_save (Bug#8779).
11351 (Vx_select_enable_clipboard_manager): New variable.
11352 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11354 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11356 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11358 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11360 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11361 in the current matrix if keep_current_p is non-zero.

11365 * bidi.c (bidi_level_of_next_char): Fix last change.
11367 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11369 Support bidi reordering of text covered by display properties.
11371 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11372 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11373 (bidi_cache_search, bidi_cache_iterator_state)
11374 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11375 (bidi_level_of_next_char, bidi_move_to_visually_next):
11376 Support character positions inside a run of characters covered by a
11378 (bidi_paragraph_init, bidi_resolve_explicit_1)
11379 (bidi_level_of_next_char): Call bidi_fetch_char and
11380 bidi_fetch_char_advance instead of FETCH_CHAR and
11381 FETCH_CHAR_ADVANCE.
11382 (bidi_init_it): Initialize new members.
11383 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11385 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11386 instead of using explicit *_CHAR codes.
11387 (bidi_resolve_explicit, bidi_resolve_weak):
11388 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11389 bidirectional text is supported only in multibyte buffers.
11390 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11391 it to initialize the frame_window_p member of struct bidi_it.
11392 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11393 (bidi_resolve_explicit, bidi_resolve_weak)
11394 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
11395 bidi_it->nchars is non-positive.
11396 (bidi_level_of_next_char): Don't try to lookup the cache for the
11397 next/previous character if nothing is cached there yet, or if we
11398 were just reseat()'ed to a new position.
11400 * xdisp.c (set_cursor_from_row): Set start and stop points
11401 according to the row's direction when priming the loop that looks
11402 for the glyph on which to display cursor.
11403 (single_display_spec_intangible_p): Function deleted.
11404 (display_prop_intangible_p): Reimplement to call
11405 handle_display_spec instead of single_display_spec_intangible_p.
11406 Accept 3 additional arguments needed by handle_display_spec.
11407 This fixes incorrect cursor motion across display property with complex
11408 values: lists, `(when COND...)' forms, etc.
11409 (single_display_spec_string_p): Support property values that are
11410 lists with the argument STRING its top-level element.
11411 (display_prop_string_p): Fix the condition for processing a
11412 property that is a list to be consistent with handle_display_spec.
11413 (handle_display_spec): New function, refactored from the
11414 last portion of handle_display_prop.
11415 (compute_display_string_pos): Accept additional argument
11416 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11417 value of a `display' property is a "replacing spec".
11418 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11419 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11420 the display property, but just return a value indicating whether
11421 the display property will replace the characters it covers.
11422 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11423 frame_window_p members of struct bidi_it.
11424 (compute_display_string_pos, compute_display_string_end):
11426 (push_it): Accept second argument POSITION, where pop_it should
11427 jump to continue iteration.
11428 (reseat_1): Initialize bidi_it.disp_pos.
11430 * keyboard.c (adjust_point_for_property): Adjust the call to
11431 display_prop_intangible_p to its new signature.
11433 * dispextern.h (struct bidi_it): New member frame_window_p.
11434 (bidi_init_it): Update prototypes.
11435 (display_prop_intangible_p): Update prototype.
11436 (compute_display_string_pos, compute_display_string_end):
11437 Declare prototypes.
11438 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11441 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11443 Malloc failure behavior now depends on size of allocation.
11444 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11445 * lisp.h: Change signatures accordingly.
11446 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11447 All callers changed. (Bug#8762)
11449 * gnutls.c: Use Emacs's memory allocators.
11450 Without this change, the gnutls library would invoke malloc etc.
11451 directly, which causes problems on non-SYNC_INPUT hosts, and which
11452 runs afoul of improving memory_full behavior. (Bug#8761)
11453 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11454 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11455 xfree instead of the default malloc, realloc, free.
11456 (Fgnutls_boot): No need to check for memory allocation failure,
11457 since xmalloc does that for us.
11459 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11460 * category.c (hash_get_category_set):
11461 * ccl.c (ccl_driver):
11462 * charset.c (Fdefine_charset_internal):
11463 * charset.h (struct charset.hash_index):
11464 * composite.c (get_composition_id, gstring_lookup_cache)
11465 (composition_gstring_put_cache):
11466 * composite.h (struct composition.hash_index):
11467 * dispextern.h (struct image.hash):
11468 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11469 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11470 (hashfn_equal, hashfn_user_defined, make_hash_table)
11471 (maybe_resize_hash_table, hash_lookup, hash_put)
11472 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11473 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11474 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11475 * image.c (make_image, search_image_cache, lookup_image)
11476 (xpm_put_color_table_h):
11477 * lisp.h (struct Lisp_Hash_Table):
11478 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11479 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11480 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11481 * alloc.c (allocate_vectorlike):
11482 Check for overflow in vector size calculations.
11483 * ccl.c (ccl_driver):
11484 Check for overflow when converting EMACS_INT to int.
11485 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11486 need to be updated by these changes.
11487 * fns.c (make_hash_table, maybe_resize_hash_table):
11488 Check for integer overflow with large hash tables.
11489 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11490 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11491 (SXHASH_REDUCE): New macro.
11492 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11493 Use it instead of discarding useful hash info with large hash values.
11494 (sxhash_float): New function.
11495 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11496 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11497 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11498 Rewrite to use FIXNUM_BITS, as this simplifies things.
11499 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11500 Adjust signatures to match updated version of code.
11501 (consing_since_gc): Now EMACS_INT, since a single hash table can
11502 use more than INT_MAX bytes.
11504 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11506 Make it possible to build with GCC-4.6+ -O2 -flto.
11508 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11510 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11512 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11513 Call minibuffer-inactive-mode.
11515 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11517 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11518 Update dependencies.
11520 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11522 * data.c (init_data): Remove code for UTS, this system is not
11525 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11527 Don't force ./temacs to start in terminal mode.
11529 * frame.c (make_initial_frame): Initialize faces in all cases, not
11530 only when CANNOT_DUMP is defined.
11531 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11533 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11535 * dispnew.c (add_window_display_history): Use const for the string
11536 pointer. Remove declaration, not needed.
11538 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11540 Use 'inline', not 'INLINE'.
11541 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11542 * alloc.c, fontset.c (INLINE): Remove.
11543 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11544 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11545 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11546 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11547 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11549 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11551 Make it possible to run ./temacs.
11553 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11554 syms_of_callproc does the same thing. Remove test for
11555 "initialized", do it in the caller.
11556 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11558 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11560 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11561 (read_minibuf): Use get_minibuffer.
11562 (syms_of_minibuf): Use DEFSYM.
11563 (Qmetadata): New var.
11564 * data.c (Qbuffer): Don't make it static.
11565 (syms_of_data): Use DEFSYM.
11567 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11569 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11570 (CCL_CODE_MIN): New macro.
11572 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11574 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11576 * eval.c (Qdebug): Now static.
11577 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11578 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11579 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11581 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11583 * image.c: Various fixes to ImageMagick code comments.
11584 (Fimagemagick_types): Doc fix.
11586 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11588 Minor fixes prompted by GCC 4.6.0 warnings.
11590 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11592 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11593 (x_clipboard_manager_save_all): Move extern decl to ...
11594 * xterm.h: ... here, so that it can be checked for consistency.
11596 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11598 * xselect.c (x_clipboard_manager_save_frame)
11599 (x_clipboard_manager_save_all): New functions.
11600 (Fx_clipboard_manager_save): Lisp function deleted.
11602 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11603 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11605 * xterm.h: Update prototype.
11607 2011-05-28 William Xu <william.xwl@gmail.com>
11609 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11610 exiting (Bug#8239).
11612 2011-05-28 Jim Meyering <meyering@redhat.com>
11614 Avoid a sign-extension bug in crypto_hash_function.
11615 * fns.c (to_uchar): Define.
11616 (crypto_hash_function): Use it to convert some newly-signed
11617 variables to unsigned, to avoid sign-extension bugs. For example,
11618 without this change, (md5 "truc") would evaluate to
11619 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11620 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11621 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11623 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11625 Integer overflow fixes.
11627 * dbusbind.c: Serial number integer overflow fixes.
11628 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11629 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11630 to hold a serial number that is too large for a fixnum.
11631 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11632 Check for serial numbers out of range. Decode any serial number
11633 that was so large that it became a float. (Bug#8722)
11635 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11636 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11637 Use XFASTINT rather than XUINT when numbers are nonnegative.
11638 (xd_append_arg, Fdbus_method_return_internal):
11639 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11640 arguments, check that Lisp number is nonnegative, rather than
11641 silently wrapping negative numbers around. (Bug#8722)
11642 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11645 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11647 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11649 ccl: Add integer overflow checks.
11650 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11651 (IN_INT_RANGE): New macros.
11652 (ccl_driver): Use them to check for integer overflow when
11653 decoding a CCL program. Many of the new checks are whether XINT (x)
11654 fits in int; it doesn't always, on 64-bit hosts. The new version
11655 doesn't catch all possible integer overflows, but it's an
11656 improvement. (Bug#8719)
11658 * alloc.c (make_event_array): Use XINT, not XUINT.
11659 There's no need for unsigned here.
11661 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11662 This follows up to the 2011-05-06 change that substituted uintptr_t
11663 for EMACS_INT. This case wasn't caught back then.
11665 Rework Fformat to avoid integer overflow issues.
11666 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11667 now (part of C89). Include <verify.h>.
11668 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11669 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11670 (Fformat): Avoid the prepass trying to compute sizes; it was only
11671 approximate and thus did not catch overflow reliably. Instead, walk
11672 through the format just once, formatting and computing sizes as we go,
11673 checking for integer overflow at every step, and allocating a larger
11674 buffer as needed. Keep track separately whether the format is
11675 multibyte. Keep only the most-recently calculated precision, rather
11676 than them all. Record whether each argument has been converted to
11677 string. Use EMACS_INT, not int, for byte and char and arg counts.
11678 Support field widths and precisions larger than INT_MAX. Avoid
11679 sprintf's undefined behavior with conversion specifications such as %#d
11680 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11681 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11682 formatting out-of-range floating point numbers with int
11683 formats. (Bug#8668)
11685 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11687 * data.c: Avoid integer truncation in expressions involving floats.
11688 * data.c: Include <intprops.h>.
11689 (arith_driver): When there's an integer overflow in an expression
11690 involving floating point, convert the integers to floating point
11691 so that the resulting value does not suffer from catastrophic
11692 integer truncation. For example, on a 64-bit host (* 4
11693 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11694 Do not rely on undefined behavior after integer overflow.
11696 merge count_size_as_multibyte, parse_str_to_multibyte
11697 * character.c, character.h (count_size_as_multibyte):
11698 Rename from parse_str_to_multibyte; all uses changed.
11699 Check for integer overflow.
11700 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11701 since it's now a duplicate of the other. This is more of
11702 a character than a buffer op, so better that it's in character.c.
11703 * fns.c, print.c: Adjust to above changes.
11705 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11707 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11709 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11711 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11712 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11713 (x_clipboard_manager_save): Now static.
11714 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11716 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11717 (crypto_hash_function): Now static.
11718 Fix pointer signedness problems. Avoid unnecessary initializations.
11720 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11722 * termhooks.h (Vselection_alist): Make it terminal-local.
11724 * terminal.c (create_terminal): Initialize it.
11726 * xselect.c: Support for clipboard managers.
11727 (Vselection_alist): Move to termhooks.h as terminal-local var.
11728 (LOCAL_SELECTION): New macro.
11729 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11730 (symbol_to_x_atom): Remove gratuitous arg.
11731 (x_handle_selection_request, lisp_data_to_selection_data)
11732 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11733 (x_own_selection, x_get_local_selection, x_convert_selection):
11734 New arg, specifying work frame. Use terminal-local Vselection_alist.
11735 (some_frame_on_display): Delete unused function.
11736 (Fx_own_selection_internal, Fx_get_selection_internal)
11737 (Fx_disown_selection_internal, Fx_selection_owner_p)
11738 (Fx_selection_exists_p): New optional frame arg.
11739 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11740 (x_handle_selection_clear): Don't treat other terminals with the
11741 same keyboard specially. Use the terminal-local Vselection_alist.
11742 (x_clear_frame_selections): Use Frun_hook_with_args.
11744 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11746 * xterm.h: Add support for those atoms.
11748 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11750 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11751 (converted_selections, conversion_fail_tag): New global variables.
11752 (x_selection_request_lisp_error): Free the above.
11753 (x_get_local_selection): Remove unnecessary code.
11754 (x_reply_selection_request): Args changed; handle arbitrary array
11755 of converted selections stored in converted_selections.
11756 Separate the XChangeProperty and SelectionNotify steps.
11757 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11758 (x_convert_selection): New function.
11759 (x_handle_selection_event): Simplify.
11760 (x_get_foreign_selection): Don't ignore incoming requests while
11761 waiting for an answer; this will fail when we implement
11762 SAVE_TARGETS, and seems unnecessary anyway.
11763 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11764 (Vx_sent_selection_functions): Doc fix.
11766 2011-05-26 Leo Liu <sdl.web@gmail.com>
11768 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11770 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11772 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11774 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11775 for fringe update if it has periodic bitmap.
11776 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11777 and fringe_bitmap_periodic_p.
11779 * fringe.c (get_fringe_bitmap_data): New function.
11780 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11781 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11782 row. Mark glyph row for fringe update if periodicity changed.
11784 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11785 for fringe update unless it has periodic bitmap.
11787 2011-05-25 Kenichi Handa <handa@m17n.org>
11789 * xdisp.c (get_next_display_element): Set correct it->face_id for
11790 a static composition.
11792 2011-05-24 Leo Liu <sdl.web@gmail.com>
11795 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11797 * fns.c (crypto_hash_function, Fsha1): New function.
11798 (Fmd5): Use crypto_hash_function.
11799 (syms_of_fns): Add Ssha1.
11801 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11803 * gnutls.c: Remove unused macros.
11804 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11805 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11806 Remove macros that are defined and never used.
11807 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11809 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11811 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11812 (Fx_get_selection_internal): Minor cleanup.
11813 (Fx_own_selection_internal): Rename arguments for consistency with
11816 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11818 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11820 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11822 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11824 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11826 * dispnew.c (scrolling_window): Don't exclude the case that the
11827 last enabled row in the desired matrix touches the bottom boundary.
11829 2011-05-21 Glenn Morris <rgm@gnu.org>
11831 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11832 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11833 and add some more files.
11835 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11837 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11838 report_file_error introduced by the change from 2011-05-07.
11840 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11842 * systime.h (Time): Define only if emacs is defined.
11843 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11844 where the include path doesn't have X11/X.h by default. See
11845 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11847 2011-05-20 Kenichi Handa <handa@m17n.org>
11849 * composite.c (find_automatic_composition): Fix previous change.
11851 2011-05-20 Glenn Morris <rgm@gnu.org>
11853 * lisp.mk: New file, split from Makefile.in.
11854 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11855 (shortlisp): Remove.
11856 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11858 2011-05-19 Glenn Morris <rgm@gnu.org>
11860 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11861 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11862 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11863 (lisp): Set the order to that of loadup.el.
11864 (shortlisp): Make it a copy of $lisp.
11865 (SOME_MACHINE_LISP): Remove.
11866 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11867 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11869 2011-05-18 Kenichi Handa <handa@m17n.org>
11871 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11872 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11873 (find_automatic_composition): Mostly rewrite for efficiency.
11875 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11877 * makefile.w32-in: Update dependencies.
11879 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11881 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11882 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11884 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11886 Fix some integer overflow issues, such as string length overflow.
11888 * insdel.c (count_size_as_multibyte): Check for string overflow.
11890 * character.c (lisp_string_width): Check for string overflow.
11891 Use EMACS_INT, not int, for string indexes and lengths; in
11892 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11893 the resulting string length overflows an EMACS_INT; instead,
11894 report a string overflow if no precision given. When checking for
11895 precision exhaustion, use a check that cannot possibly have
11896 integer overflow. (Bug#8675)
11897 * character.h (lisp_string_width): Adjust to new signature.
11899 * alloc.c (string_overflow): New function.
11900 (Fmake_string): Use it. This doesn't change behavior, but saves
11901 a few bytes and will simplify future changes.
11902 * character.c (string_escape_byte8): Likewise.
11903 * lisp.h (string_overflow): New decl.
11905 Fixups, following up to the user-interface timestamp change.
11906 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11907 for UI timestamps, instead of unsigned long.
11908 * msdos.c (mouse_get_pos): Likewise.
11909 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11910 * w32gui.h (Time): Define by including "systime.h" rather than by
11911 declaring it ourselves. (Bug#8664)
11913 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11914 * image.c (clear_image_cache): Likewise.
11916 * term.c (term_mouse_position): Don't assume time_t wraparound.
11918 Be more systematic about user-interface timestamps.
11919 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11920 and sometimes 'EMACS_UINT', to represent these timestamps.
11921 This change causes it to use 'Time' uniformly, as that's what X uses.
11922 This makes the code easier to follow, and makes it easier to catch
11923 integer overflow bugs such as Bug#8664.
11924 * frame.c (Fmouse_position, Fmouse_pixel_position):
11925 Use Time, not unsigned long, for user-interface timestamps.
11926 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11927 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11928 * keyboard.h (last_event_timestamp): Likewise.
11929 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11930 * menu.h (xmenu_show): Likewise.
11931 * term.c (term_mouse_position): Likewise.
11932 * termhooks.h (struct input_event.timestamp): Likewise.
11933 (struct terminal.mouse_position_hook): Likewise.
11934 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11935 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11936 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11937 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11938 what it was before.
11939 * menu.h, termhooks.h: Include "systime.h", for Time.
11941 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11942 Don't assume that the difference between two unsigned long values
11943 can fit into an integer. At this point, we know button_down_time
11944 <= event->timestamp, so the difference must be nonnegative, so
11945 there's no need to cast the result if double-click-time is
11946 nonnegative, as it should be; check that it's nonnegative, just in
11947 case. This bug is triggered when events are more than 2**31 ms
11948 apart (about 25 days). (Bug#8664)
11950 * xselect.c (last_event_timestamp): Remove duplicate decl.
11951 (x_own_selection): Remove needless cast to unsigned long.
11953 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11954 that always fit in int. Use a sentinel instead of a counter, to
11955 avoid a temp and to allay GCC's concerns about possible int overflow.
11956 * frame.h (struct frame): Use int for menu_bar_items_used
11957 instead of EMACS_INT, since it always fits in int.
11959 * menu.c (grow_menu_items): Check for int overflow.
11961 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11963 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11964 Before, the code was not consistent. These values cannot exceed
11965 2**31 - 1 so there's no need to make them unsigned.
11966 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11967 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11968 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11970 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11972 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11973 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11974 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11975 presumably because the widths might not match.
11977 * window.c (size_window): Avoid needless test at loop start.
11979 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11981 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11983 2011-05-12 Drew Adams <drew.adams@oracle.com>
11985 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11987 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11989 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11990 `width' to `bar_area_x' and `bar_area_width', respectively.
11991 (x_scroll_run): Take account of fringe background extension.
11993 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11994 Rename local vars `left' and `width' to `bar_area_x' and
11995 `bar_area_width', respectively.
11996 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11997 background extension.
11999 2011-05-10 Jim Meyering <meyering@redhat.com>
12001 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12003 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12005 * image.c (Finit_image_library): Return t for built-in image types,
12006 like pbm and xbm. (Bug#8640)
12008 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12010 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12012 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12014 * w32console.c (Fset_screen_color): Doc fix.
12015 (Fget_screen_color): New function.
12016 (syms_of_ntterm): Defsubr it.
12018 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12019 unlink the temporary file if Fcall_process didn't create it in the
12021 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12022 child process will be redirected to a file specified with `:file'.
12023 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12024 cue to call_process_cleanup not to close that handle.
12026 2011-05-07 Ben Key <bkey76@gmail.com>
12028 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12029 one of two shell specific rules, either bootstrap-temacs-CMD or
12030 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12031 to the previous implementation of the bootstrap-temacs rule.
12032 The bootstrap-temacs-CMD rule is similar to the previous
12033 implementation of the bootstrap-temacs rule except that it
12034 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12037 These changes, along with some changes to nt/configure.bat,
12038 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12039 earlier fix to add support for --cflags and --ldflags options
12040 that include quotes so that it works whether make uses cmd or
12043 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12045 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12046 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12048 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12049 a string. Handle both cases.
12050 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12051 (Fdbus_register_method): Use Qinvalid_function.
12053 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12055 * makefile.w32-in: Update dependencies.
12056 (LISP_H): Add inttypes.h and stdin.h.
12057 (PROCESS_H): Add unistd.h.
12059 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12061 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12062 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12064 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12066 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12068 * term.c (vfatal): Remove stray call to va_end.
12069 It's not needed and the C Standard doesn't allow it here anyway.
12071 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12072 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12074 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12077 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12079 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12081 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12083 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12085 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12087 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12088 * charset.c (Fdefine_charset_internal): Don't initialize
12089 charset.code_space[15]. The value was garbage, on hosts with
12090 32-bit int (Bug#8600).
12092 * lread.c (read_integer): Be more consistent with string-to-number.
12093 Use string_to_number to do the actual conversion; this avoids
12094 rounding errors and fixes some other screwups. Without this fix,
12095 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12096 (digit_to_number): Move earlier, for benefit of read_integer.
12097 Return -1 if the digit is out of range for the base, -2 if it is
12098 not a digit in any supported base. (Bug#8602)
12100 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12102 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12103 to match comment at start of function. This also removes a
12104 GCC warning about overflow in a 32+64-bit port.
12106 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12108 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12109 Reported by Stefan Monnier in
12110 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12111 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12112 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12114 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12115 (EMACS_UINTPTR): Likewise, with uintptr_t.
12117 * lisp.h: Prefer 64-bit EMACS_INT if available.
12118 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12119 on 32-bit hosts that have 64-bit int, so that they can access
12121 However, temporarily disable this change unless the temporary
12122 symbol WIDE_EMACS_INT is defined.
12124 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12126 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12127 This removes an assumption that EMACS_INT and long are the same
12128 width as pointers. The assumption is true for Emacs porting targets
12129 now, but we want to make other targets possible.
12130 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12131 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12132 In the rest of the code, change types of integers that hold casted
12133 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12134 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12135 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12136 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12137 No need to cast type when ORing.
12138 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12139 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12140 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12141 assume EMACS_INT is the same width as char *.
12142 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12143 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12144 Remove no-longer-needed casts.
12145 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12146 (xg_tool_bar_help_callback, xg_make_tool_item):
12147 Use EMACS_INTPTR to hold an integer
12148 that will be cast to void *; this can avoid a GCC warning
12149 if EMACS_INT is not the same width as void *.
12150 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12151 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12152 (current_message_1, set_message_1):
12153 Use a local to convert to proper width without a cast.
12154 * xmenu.c (dialog_selection_callback): Likewise.
12156 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12157 Also, don't assume VALBITS / RAND_BITS is less than 5,
12158 and don't rely on undefined behavior when shifting a 1 left into
12160 * lisp.h (get_random): Change signature to match.
12162 * lread.c (hash_string): Use size_t, not int, for hash computation.
12163 Normally we prefer signed values; but hashing is special, because
12164 it's better to use unsigned division on hash table sizes so that
12165 the remainder is nonnegative. Also, size_t is the natural width
12166 for hashing into memory. The previous code used 'int', which doesn't
12167 retain enough info to hash well into very large tables.
12168 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12170 * dbusbind.c: Don't possibly lose pointer info when converting.
12171 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12172 Use XPNTR rather than XHASH, so that the high-order bits of
12173 the pointer aren't lost when converting through void *.
12175 * eval.c (Fautoload): Don't double-shift a pointer.
12177 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12179 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12181 * gnutls.c (DEF_GNUTLS_FN):
12182 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12184 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12186 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12189 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12191 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12192 New version that can reserve upto 2GB of heap space.
12194 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12196 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12198 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12200 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to

12260 * process.c: Include lisp.h before w32.h, not after.
12261 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12262 instead of gnutls_record_check_pending.
12264 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12266 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12268 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

12314 rather than `XVECTOR (FOO)->size'.
12316 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12317 inttypes.h, as a gnulib replacement is used if it not available in
12320 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12322 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

12332 charbuf for the composition carryover bytes.
12334 2011-04-21 Eli Zaretskii <eliz@gnu.org>

12339 %llo or %llx format is passed. (Bug#8545)
12341 * window.c (window_scroll_line_based): Use a marker instead of
12342 simple variables to record original value of point. (Bug#7952)
12344 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12345 produced by %s or %c overflows available buffer space. (Bug#8545)
12347 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12349 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12350 (SIZE_MAX): Move defn after all includes, as they might #define it.
12352 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12354 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12356 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12358 * keyboard.c (Qdelayed_warnings_hook): Define.
12359 (command_loop_1): Run `delayed-warnings-hook'
12360 if Vdelayed_warnings_list is non-nil.
12361 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12362 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12364 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12366 * doprnt.c (doprnt): Don't return value smaller than the buffer
12367 size if the message was truncated. (Bug#8545).
12369 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12371 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12372 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12374 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12376 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12378 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12380 * makefile.w32-in: Update dependencies.
12382 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12384 Improve `doprnt' and its usage. (Bug#8545)
12385 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12386 `format_end'. Remove support for %l as a conversion specifier.
12387 Don't use xrealloc. Improve diagnostics when the %l size modifier
12388 is used. Update the commentary.
12390 * eval.c (verror): Simplify calculation of size_t.
12392 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12395 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12397 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12400 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12402 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12403 This makes this file independent of the recent pseudovector change.
12405 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12407 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12409 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12410 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12411 Remove unused local.
12412 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12414 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12415 GCC 4.6.0 optimizes based on type-based alias analysis.
12416 For example, if b is of type struct buffer * and v of type struct
12417 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12418 != &v->size, and therefore "v->size = 1; b->size = 2; return
12419 v->size;" must therefore return 1. This assumption is incorrect
12420 for Emacs, since it type-puns struct Lisp_Vector * with many other
12421 types. To fix this problem, this patch adds a new type struct
12422 vectorlike_header that documents the constraints on layout of vectors
12423 and pseudovectors, and helps optimizing compilers not get fooled
12424 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12425 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12426 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12428 (XSETPVECTYPE): Rewrite in terms of new macro.
12429 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12430 This is a bit clearer, and further avoids the possibility of
12431 undesirable aliasing.
12432 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12433 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12434 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12435 since Lisp_Subr is a special case (no "next" field).
12436 (ASIZE): Now uses header.size rather than size.
12437 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12438 to avoid the hassle of writing XVECTOR (foo)->header.size.
12439 (struct vectorlike_header): New type.
12440 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12441 object, to help avoid aliasing.
12442 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12443 (SUBRP): Likewise, since Lisp_Subr is a special case.
12444 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12445 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12446 (struct Lisp_Hash_Table): Combine first two members into a single
12447 struct vectorlike_header member. All uses of "size" and "next" members
12448 changed to be "header.size" and "header.next".
12449 * buffer.h (struct buffer): Likewise.
12450 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12451 * frame.h (struct frame): Likewise.
12452 * process.h (struct Lisp_Process): Likewise.
12453 * termhooks.h (struct terminal): Likewise.
12454 * window.c (struct save_window_data, struct saved_window): Likewise.
12455 * window.h (struct window): Likewise.
12456 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12457 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12458 * buffer.c (init_buffer_once): Likewise.
12459 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12461 * process.c (Fformat_network_address): Use local var for size,
12464 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12466 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12467 * data.c (atof): Remove decl; no longer used or needed.
12468 (digit_to_number): Move to lread.c.
12469 (Fstring_to_number): Use new string_to_number function, to be
12470 consistent with how the Lisp reader treats infinities and NaNs.
12471 Do not assume that floating-point numbers represent EMACS_INT
12472 without losing information; this is not true on most 64-bit hosts.
12473 Avoid double-rounding errors, by insisting on integers when
12474 parsing non-base-10 numbers, as the documentation specifies.
12475 * lisp.h (string_to_number): New decl, replacing ...
12476 (isfloat_string): Remove.
12477 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12478 (read1): Do not accept +. and -. as integers; this
12479 appears to have been a coding error. Similarly, do not accept
12480 strings like +-1e0 as floating point numbers. Do not report
12481 overflow for integer overflows unless the base is not 10 which
12482 means we have no simple and reliable way to continue.
12483 Break out the floating-point parsing into a new
12484 function string_to_number, so that Fstring_to_number parses
12485 floating point numbers consistently with the Lisp reader.
12486 (digit_to_number): Move here from data.c. Make it static inline.
12487 (E_CHAR, EXP_INT): Remove, replacing with ...
12488 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12489 (string_to_number): New function, replacing isfloat_string.
12490 This function checks for valid syntax and produces the resulting
12491 Lisp float number too. Rework it so that string-to-number
12492 no longer mishandles examples like "1.0e+". Use strtoumax,
12493 so that overflow for non-base-10 numbers is reported only when
12494 there's no portable and simple way to convert to floating point.
12496 * textprop.c (set_text_properties_1): Rewrite for clarity,
12497 and to avoid GCC warning about integer overflow.
12499 * intervals.h (struct interval): Use EMACS_INT for members
12500 where EMACS_UINT might cause problems. See
12501 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12502 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12503 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12505 (offset_intervals): Tell GCC not to worry about length overflow
12506 when negating a negative length.
12508 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12509 (overrun_check_free): Likewise.
12511 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12512 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12515 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12516 (gnutls_make_error): Rename local to avoid shadowing.
12517 (gnutls_emacs_global_deinit): ifdef out; not used.
12518 (Fgnutls_boot): Use const for pointer to readonly storage.
12519 Comment out unused local. Fix pointer signedness problems.
12521 * lread.c (openp): Don't stuff size_t into an 'int'.
12522 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12523 about possible signed overflow.
12525 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12526 (GDK_KEY_g): Don't define if already defined.
12527 (xg_prepare_tooltip): Avoid pointer signedness problem.
12528 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12530 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12531 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12533 * xfns.c (Fx_window_property): Simplify a bit,
12534 to make a bit faster and to avoid GCC 4.6.0 warning.
12535 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12537 * fns.c (internal_equal): Don't assume size_t fits in int.
12539 * alloc.c (compact_small_strings): Tighten assertion a little.
12541 Replace pEd with more-general pI, and fix some printf arg casts.
12542 * lisp.h (pI): New macro, generalizing old pEd macro to other
12543 conversion specifiers. For example, use "...%"pI"d..." rather
12544 than "...%"pEd"...".
12545 (pEd): Remove. All uses replaced with similar uses of pI.
12546 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12547 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12548 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12549 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12550 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12551 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12552 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12554 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12555 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12556 * print.c (safe_debug_print, print_object): Likewise.
12557 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12559 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12560 avoiding the 0 flag, which is not portable.
12561 * process.c (Fmake_network_process): Use pI to avoid cast.
12562 * region-cache.c (pp_cache): Likewise.
12563 * xdisp.c (decode_mode_spec): Likewise.
12564 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12565 behavior on 64-bit hosts with printf arg.
12566 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12567 (x_stop_queuing_selection_requests): Likewise.
12568 (x_get_window_property): Don't truncate byte count to an 'int'
12571 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12572 here, since it parses constructs like leading '-' and spaces,
12573 which are not wanted; and it overflows with large numbers.
12574 Instead, simply match F[0-9]+, which is what is wanted anyway.
12576 * alloc.c: Remove unportable assumptions about struct layout.
12577 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12578 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12579 (allocate_vectorlike, make_pure_vector): Use the new macros,
12580 plus offsetof, to remove unportable assumptions about struct layout.
12581 These assumptions hold on all porting targets that I know of, but
12582 they are not guaranteed, they're easy to remove, and removing them
12583 makes further changes easier.
12585 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12586 This doesn't fix a bug but makes the code clearer.
12587 (string_overrun_cookie): Now const. Use initializers that
12588 don't formally overflow signed char, to avoid warnings.
12589 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12590 can cause Emacs to crash when string overrun checking is enabled.
12591 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12592 multiple of sizeof (EMACS_INT); it need not be, if
12593 alignof(EMACS_INT) < sizeof (EMACS_INT).
12594 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12596 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12598 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12600 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12602 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12603 supposed to be handshaking. (Bug#8556)
12604 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12606 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12608 * lisp.h (Qdebug): List symbol.
12609 * eval.c (Qdebug): Restore global linkage.
12610 * keyboard.c (debug-on-event): New variable.
12611 (handle_user_signal): Break into debugger when debug-on-event
12612 matches the current signal symbol.
12614 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>

13367 to see whether these functions can be called from other modules.
13368 DEFUN now defines a static function. To make the function external
13369 so that it can be used in other C modules, use the new macro DEFUE.

13447 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13448 since callers should never pass a negative size.
13449 Change the signature to match that of plain 'read' and 'write'; see
13450 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13451 * lisp.h: Update prototypes of emacs_write and emacs_read.
13453 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13455 * xdisp.c (redisplay_window): Don't try to determine the character
13456 position of the scroll margin if the window start point w->startp
13457 is outside the buffer's accessible region. (Bug#8468)
13459 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13461 Fix write-region and its subroutines for buffers > 2GB.
13462 * fileio.c (a_write, e_write): Modify declaration of arguments and
13463 local variables to support buffers larger than 2GB.
13464 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13466 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13467 argument, local variables, and return value.
13469 * lisp.h: Update prototypes of emacs_write and emacs_read.
13471 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13473 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13475 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

13479 * xdisp.c (vmessage): Use a better test for character truncation.
13481 * charset.c (load_charset_map): <, not <=, for optimization,

13491 * callint.c (Fcall_interactively): <, not <=, for optimization.
13492 (Fcall_interactively): Count the number of arguments produced,
13493 not the number of arguments given. This is simpler and lets GCC
13494 4.6.0 generate slightly better code.
13496 * ftfont.c: Distingish more carefully between FcChar8 and char.
13497 The previous code passed unsigned char * to a functions like
13498 strlen and xstrcasecmp that expect char *, which does not
13499 conform to the C standard.
13500 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13501 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13502 char * when the C standard requires it.
13504 * keyboard.c (read_char): Remove unused var.
13506 * eval.c: Port to Windows vsnprintf (Bug#8435).

13509 (verror): Do not give up if vsnprintf returns a negative count.
13510 Instead, grow the buffer. This ports to Windows vsnprintf, which
13511 does not conform to C99. Problem reported by Eli Zaretskii.
13512 Also, simplify the allocation scheme, by avoiding the need for
13513 calling realloc, and removing the ALLOCATED variable.
13515 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13517 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13518 But keep the doprint source code for now, as we might revamp it
13519 and use it again (Bug#8435).
13520 * lisp.h (doprnt): Remove.
13521 * Makefile.in (base_obj): Remove doprnt.o.
13522 * deps.mk (doprnt.o): Remove.
13524 error: Print 32- and 64-bit integers portably (Bug#8435).
13525 Without this change, on typical 64-bit hosts error ("...%d...", N)
13526 was used to print both 32- and 64-bit integers N, which relied on
13527 undefined behavior.
13528 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13529 * lisp.h (error, verror): Mark as printf-like functions.
13530 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13531 Report overflow in size calculations when allocating printf buffer.
13532 Do not truncate output string at its first null byte.
13533 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13534 Truncate the output at a character boundary, since vsnprintf does not
13536 * charset.c (check_iso_charset_parameter): Convert internal
13537 character to string before calling 'error', since %c now has the
13539 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13540 overflow when computing char to be passed to 'error'. Do not
13541 pass Lisp_Object to 'error'; pass the integer instead.
13542 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13543 formatted with plain %d.
13545 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13547 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13549 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13551 * xterm.c (x_catch_errors): Remove duplicate declaration.
13553 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13555 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13557 2011-04-10 Jim Meyering <meyering@redhat.com>
13559 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13560 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13561 return ssize_t not "int", and use size_t as the buffer length.
13562 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13563 * gnutls.h: Update declarations.
13564 * process.c (read_process_output): Use ssize_t, to match.
13565 (send_process): Likewise.

13569 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13571 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13573 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13574 Use unsigned char, to match FcChar8 type definition.
13576 * xterm.c (handle_one_xevent):
13577 * xmenu.c (create_and_show_popup_menu):
13578 * xselect.c (x_decline_selection_request)
13579 (x_reply_selection_request): Avoid type-punned deref of X events.
13581 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13583 Fix some uses of `int' instead of EMACS_INT.

13591 EMACS_INT. All callers changed.
13592 (pint2hrstr): Last argument is now EMACS_INT.

13607 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13608 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13610 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13611 (encode_invocation_designation): Last argument P_NCHARS is now
13613 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13614 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13616 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.

13637 instead of using internal_with_output_to_temp_buffer.
13638 (Qhelp_form_show): New var.
13639 (syms_of_keyboard): Use DEFSYM macro.
13641 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13675 to system-supplied API.
13677 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13679 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13680 This avoids several warnings with gcc -Wstrict-overflow.
13681 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13682 directly, rather than having caller test rule sign. This avoids
13683 some unnecessary tests.
13684 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13685 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13686 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13688 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13689 (xfont_open): Avoid unnecessary tests.
13691 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13693 * composite.h, composite.c (composition_gstring_put_cache):
13694 Use EMACS_INT, not int, for length.

13697 breaking out part of COMPOSITION_DECODE_RULE.
13698 (COMPOSITION_DECODE_RULE): Use it.

13700 by using the new macro.
13702 * textprop.c (set_text_properties_1): Change while to do-while,
13703 since the condition is always true at first.
13705 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13706 (interval_deletion_adjustment): Return unsigned value.
13709 * process.c (list_processes_1, create_pty, read_process_output):

13725 * print.c (print_error_message): Avoid int overflow.
13727 * font.c (font_list_entities): Redo for clarity,
13728 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13730 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13731 (font_score): Avoid potential overflow in diff calculation.
13733 * fns.c (substring_both): Remove var that is set but not used.
13734 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13736 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13738 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13739 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13740 can always succeed if overflow has undefined behavior.
13742 * search.c (boyer_moore, wordify): Remove vars set but not used.
13743 (wordify): Omit three unnecessary tests.
13745 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13746 All callers changed. This avoids the need for an unused var.
13748 * casefiddle.c (casify_region): Remove var that is set but not used.
13750 * dired.c (file_name_completion): Remove var that is set but not used.
13752 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13754 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13755 (Finsert_file_contents): Remove unnecessary code checking fd.
13757 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13758 Check for integer overflow on size calculations.
13760 * buffer.c (Fprevious_overlay_change): Remove var that is set
13763 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13764 Remove vars that are set but not used.
13765 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13766 (timer_check_2): Mark vars as initialized.
13768 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13770 * image.c (lookup_image): Remove var that is set but not used.
13771 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13773 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13774 that are set but not used.
13776 * xfns.c (make_invisible_cursor): Don't return garbage
13777 if XCreateBitmapFromData fails (Bug#8410).
13779 * xselect.c (x_get_local_selection, x_handle_property_notify):
13780 Remove vars that are set but not used.
13782 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13783 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13785 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13786 Remove var that is set but not used.
13787 (scroll_bar_windows_size): Now size_t, not int.
13788 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13789 Check for overflow.
13791 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13792 (map_tty_color) [!defined MSDOS]: Likewise.
13794 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13796 * coding.c: Remove vars that are set but not used.
13797 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13798 All callers changed.

13800 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13801 (decode_coding_charset): Remove vars that are set but not used.
13803 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13804 that is set but not used.
13806 * print.c (print_object): Remove var that is set but not used.
13808 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13809 The gnulib version avoids calling malloc in the usual case,
13810 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13811 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13812 * filelock.c (current_lock_owner): Likewise.
13813 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13814 * sysdep.c: Include allocator.h, careadlinkat.h.
13815 (emacs_no_realloc_allocator): New static constant.
13816 (emacs_readlink): New function.
13817 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13818 ../lib/careadlinkat.h.
13820 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13822 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13823 first non-nil return value).
13825 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13827 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

13837 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13838 and thereabouts. All callers changed.
13839 (get_per_char_metric): Remove parameter `f', unused since
13840 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13842 2011-04-02 Jim Meyering <meyering@redhat.com>
13844 do not dereference NULL upon failed strdup
13845 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13846 (ns_get_family): Likewise.
13848 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13850 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13852 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13854 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

13872 (syms_of_lread): Declare `lexical-binding'.
13874 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13876 * keyboard.c (eval_dyn): New fun.
13877 (menu_item_eval_property): Use it.
13879 * image.c (parse_image_spec): Use Ffunctionp.
13881 * fns.c (concat, mapcar1): Accept byte-code-functions.
13883 * eval.c (Fsetq): Handle lexical vars.
13884 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13885 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13886 (FletX, Flet): Obey lexical binding.
13887 (Fcommandp): Handle closures.
13888 (Feval): New `lexical' arg.
13889 (eval_sub): New function extracted from Feval. Use it almost
13890 everywhere where Feval was used. Look up vars in lexical env.
13892 (Ffunctionp): Move from subr.el.
13893 (Ffuncall): Handle closures.
13894 (apply_lambda): Remove `eval_flags'.
13895 (funcall_lambda): Handle closures and new byte-code-functions.
13896 (Fspecial_variable_p): New function.
13897 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13898 but without exporting it to Lisp.
13900 * doc.c (Fdocumentation, store_function_docstring):
13901 * data.c (Finteractive_form): Handle closures.
13903 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13906 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13908 (exec_byte_code): New function extracted from Fbyte_code to handle new
13909 calling convention for byte-code-functions. Add new byte-codes.
13911 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13913 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13915 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13917 * xdisp.c (redisplay_internal): Fix prototype.
13919 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13921 * xdisp.c (SCROLL_LIMIT): New macro.
13922 (try_scrolling): Use it when setting scroll_limit.
13923 Limit scrolling to 100 screen lines.
13924 (redisplay_window): Even when falling back on "recentering",
13925 position point in the window according to scroll-conservatively,
13926 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13928 (try_scrolling): When point is above the window, allow searching
13929 as far as scroll_max, or one screenful, to compute vertical
13930 distance from PT to the scroll margin position. This prevents
13931 try_scrolling from unnecessarily failing when
13932 scroll-conservatively is set to a value slightly larger than the
13933 window height. Clean up the case of PT below the margin at bottom
13934 of window: scroll_max can no longer be INT_MAX. When aggressive
13935 scrolling is in use, don't let point enter the opposite scroll
13936 margin as result of the scroll.
13937 (syms_of_xdisp) <scroll-conservatively>: Document the
13938 threshold of 100 lines for never-recentering scrolling.

13945 (message_log_check_duplicate): Remove parameters `prev_bol' and
13946 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13947 (redisplay_internal): Remove parameter `preserve_echo_area',
13948 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13950 * indent.c (Fvertical_motion):
13951 * window.c (window_scroll_pixel_based, Frecenter):
13952 Don't pass `need_y_p' to `move_it_by_lines'.
13954 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13956 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13957 steal a few bits to be more compact.
13958 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13959 Remove unneeded casts.
13961 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13963 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13965 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13966 binding" message (bug#7967).
13968 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13970 Fix more problems found by GCC 4.6.0's static checks.
13972 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13973 Remove unused local var.
13975 * editfns.c (Fmessage_box): Remove unused local var.
13977 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13978 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13979 Omit unused local vars.
13980 * window.c (shrink_windows): Omit unused local var.
13981 * menu.c (digest_single_submenu): Omit unused local var.
13982 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13983 Omit unused local var.
13985 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13986 Don't assume string length fits in int.
13987 (keyremap_step, read_key_sequence): Use size_t for sizes.
13988 (read_key_sequence): Don't check last_real_key_start redundantly.
13990 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13991 instead of alloca (Bug#8344).
13993 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13994 (Fbacktrace_frame): Don't assume nframes fits in int.
13996 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13998 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14001 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14003 * cm.c (calccost): Turn while-do into do-while, for clarity.
14005 * keyboard.c (syms_of_keyboard): Use the same style as later
14006 in this function when indexing through an array. This also
14007 works around GCC bug 48267.
14009 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14011 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

14014 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14016 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14017 This avoids undefined behavior on integer overflow, and is a bit
14018 more convenient anyway since it is compared to a size_t variable.
14020 Variadic C functions now count arguments with size_t, not int.
14021 This avoids an unnecessary limitation on 64-bit machines, which
14022 caused (substring ...) to crash on large vectors (Bug#8344).
14023 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14024 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14025 All variadic functions and their callers changed accordingly.
14026 (struct gcpro.nvars): Now size_t, not int. All uses changed.
14027 * data.c (arith_driver, float_arith_driver): Likewise.
14028 * editfns.c (general_insert_function): Likewise.
14029 * eval.c (struct backtrace.nargs, interactive_p)
14030 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14031 (funcall_lambda, mark_backtrace): Likewise.
14032 * fns.c (concat): Likewise.
14033 * frame.c (x_set_frame_parameters): Likewise.
14034 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14035 0 if not found, not -1. All callers changed.
14037 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14038 (stack_copy_size): Now size_t, not int.
14039 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14041 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14043 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14044 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14045 All callers changed.
14047 * lisp.h (multibyte_char_to_unibyte):
14048 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14049 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14050 * character.h (CHAR_TO_BYTE8):
14051 * cmds.c (internal_self_insert):
14052 * editfns.c (general_insert_function):
14053 * keymap.c (push_key_description):
14054 * search.c (Freplace_match):
14055 * xdisp.c (message_dolog, set_message_1): All callers changed.
14057 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14059 * keyboard.c (safe_run_hook_funcall): New function.
14060 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14061 don't set the hook to nil, but remove the offending function instead.
14062 (Qcommand_hook_internal): Remove, unused.
14063 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14064 Vcommand_hook_internal.
14066 * eval.c (enum run_hooks_condition): Remove.
14067 (funcall_nil, funcall_not): New functions.
14068 (run_hook_with_args): Call each function through a `funcall' argument.
14069 Remove `cond' argument, now redundant.
14070 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14071 (Frun_hook_with_args_until_failure): Adjust accordingly.
14072 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14074 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14076 * dispextern.h (string_buffer_position): Remove declaration.
14078 * print.c (strout): Remove parameter `multibyte', unused since
14079 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14081 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14082 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14083 All callers changed.
14085 * w32.c (_wsa_errlist): Use braces for struct initializers.
14087 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14088 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14089 All callers changed.
14090 (string_buffer_position): Likewise. Also, make static (it's never
14091 used outside xdisp.c).
14092 (cursor_row_p): Remove parameter `w', unused since
14093 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14095 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14096 All callers changed.
14098 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14100 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14111 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14113 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

14126 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14128 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14129 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14131 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14133 * w32.c (read_unc_volume): Use parameter `henum', instead of
14134 global variable `wget_enum_handle'.
14136 * keymap.c (describe_vector): Remove parameters `indices' and
14137 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14149 * xmenu.c (show_help_event, menu_help_callback):
14150 Adjust calls to `show_help_echo'.
14152 * gtkutil.c (xg_maybe_add_timer):
14153 * keyboard.c (readable_events):
14154 * process.c (wait_reading_process_output):
14155 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14157 * insdel.c (adjust_markers_gap_motion):
14158 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

14232 2011-03-23 Julien Danjou <julien@danjou.info>
14234 * term.c (Fsuspend_tty, Fresume_tty):
14235 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14236 * window.c (temp_output_buffer_show):

14242 * cmds.c (internal_self_insert):
14243 * callint.c (Fcall_interactively):
14244 * buffer.c (Fkill_all_local_variables):
14245 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14247 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14248 unconditionally since it does the check itself.
14250 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14252 Fix more problems found by GCC 4.5.2's static checks.
14254 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14255 the first time through the loop, since we know p0 < p1 then.
14256 This also avoids a gcc -Wstrict-overflow warning.
14258 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14259 leading to a memory leak, possible in functions like
14260 load_charset_map_from_file that can allocate an unbounded number
14261 of objects (Bug#8318).
14263 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14264 that could (at least in theory) be that large.
14266 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14267 This is less likely to overflow, and avoids undefined behavior if
14268 overflow does occur. All callers changed. Use strtoul to scan
14269 for the unsigned long integer.
14270 (pint2hrstr): Simplify and tune code slightly.
14271 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14279 This also avoids a warning with gcc -Wstrict-overflow.
14281 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14284 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14286 * process.c (Fmake_network_process): Use socklen_t, not int,
14287 where POSIX says socklen_t is required in portable programs.
14288 This fixes a porting bug on hosts like 64-bit HP-UX, where
14289 socklen_t is wider than int (Bug#8277).
14290 (Fmake_network_process, server_accept_connection):
14291 (wait_reading_process_output, read_process_output):
14294 * process.c: Rename or move locals to avoid shadowing.
14295 (list_processes_1, Fmake_network_process):
14296 (read_process_output_error_handler, exec_sentinel_error_handler):
14297 Rename or move locals.
14298 (Fmake_network_process): Define label "retry_connect" only if needed.
14299 (Fnetwork_interface_info): Fix pointer signedness.

14301 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14302 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14304 Make tparam.h and terminfo.c consistent.
14305 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14306 Include tparam.h instead, since it declares them.
14307 * cm.h (PC): Remove extern decl; tparam.h now does this.
14308 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14309 * terminfo.c: Include tparam.h, to check interfaces.
14310 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14311 (tparam): Adjust signature to match interface in tparam.h;
14312 this removes some undefined behavior. Check that outstring and len
14313 are zero, which they always are with Emacs.
14314 * tparam.h (PC, BC, UP): New extern decls.
14316 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14317 (xftfont_open): Rename locals to avoid shadowing.
14319 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14320 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14321 (OTF_TAG_SYM): Omit macro if not needed.
14322 (ftfont_list): Remove unused local.
14323 (get_adstyle_property, ftfont_pattern_entity):
14324 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14325 Rename locals to avoid shadowing.
14327 * xfont.c (xfont_list_family): Mark var as initialized.
14329 * xml.c (make_dom): Now static.
14331 * composite.c (composition_compute_stop_pos): Rename local to
14333 (composition_reseat_it): Remove unused locals.
14334 (find_automatic_composition, composition_adjust_point): Likewise.
14335 (composition_update_it): Mark var as initialized.
14336 (find_automatic_composition): Mark vars as initialized,
14337 with a FIXME (Bug#8290).
14339 character.h: Rename locals to avoid shadowing.
14340 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14341 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14342 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14343 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14344 to avoid shadowing.
14346 * textprop.c (property_change_between_p): Remove; unused.
14348 * intervals.c (interval_start_pos): Now static.
14350 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
14352 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
14353 Rename locals to avoid shadowing.
14355 * sound.c (wav_play, au_play, Fplay_sound_internal):
14356 Fix pointer signedness.
14357 (alsa_choose_format): Remove unused local var.
14358 (wav_play): Initialize a variable to 0, to prevent undefined
14359 behavior (Bug#8278).
14361 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14363 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14365 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14366 clobbering (Bug#8298).
14367 * sysdep.c (sys_subshell): Likewise.
14368 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14370 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14371 This should get cleaned up, so that child_setup has the
14372 same signature on all platforms.
14374 * callproc.c (call_process_cleanup): Now static.
14375 (relocate_fd): Rename locals to avoid shadowing.
14377 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14379 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14380 not to be necessary, and produces flickering.
14382 2011-03-20 Glenn Morris <rgm@gnu.org>
14384 * config.in: Remove file.
14386 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14388 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14389 are now in src/globals.h.
14390 (syms_of_minibuf): Remove spurious & from previous change.

14400 * xfaces.c (Fx_load_color_file):
14401 Read color file from absolute filename (bug#8250).
14403 2011-03-19 Juanma Barranquero <lekktu@gmail.com>

14467 instead of using an uninitialized var.
14468 (font_sort_entities): Mark var as initialized.
14470 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.

14487 * alloc.c (mark_backtrace): Move decl from here ...
14488 * lisp.h: ... to here, so that it can be checked.
14490 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
14491 (Fdefvar): Rewrite so as not to use empty "else".
14492 (lisp_indirect_variable): Name an expression,
14493 to avoid gcc -Wbad-function-cast warning.

14496 * callint.c (quotify_arg, quotify_args): Now static.
14497 (Fcall_interactively): Rename locals to avoid shadowing.

14505 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14506 some of which prompt warnings from gcc -Wbad-function-cast.
14507 (Fformat_time_string, Fencode_time, Finsert_char):
14508 (Ftranslate_region_internal, Fformat):

14536 (Fmemory_limit): Cast sbrk's returned value to char *.
14538 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14539 avoids undefined behavior in theory.
14541 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14543 Use functions, not macros, for up- and down-casing (Bug#8254).
14544 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14545 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14546 to use the following functions instead of these macros.
14547 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14548 EMACS_INT, since callers assume the returned value fits in int.
14549 (upcase1): Likewise, for UPCASE_TABLE.
14550 (uppercasep, lowercasep, upcase): New static inline functions.
14551 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14557 (regex_compile, re_search_2, re_match_2_internal):
14558 Remove unused local vars.

14560 which gcc can warn about.
14561 (regex_compile, re_match_2_internal): Mark locals as initialized.
14562 (RETALLOC_IF): Define only if needed.
14563 (WORDCHAR_P): Likewise. This one is never needed, but is used
14564 only in a comment talking about a compiler bug, so put inside
14565 the #if 0 of that comment.
14566 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14567 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14570 * search.c (boyer_moore): Rename locals to avoid shadowing.

14585 Rename locals to avoid shadowing.
14586 (Fvertical_motion): Mark locals as initialized.
14588 * casefiddle.c (casify_object, casify_region): Now static.
14589 (casify_region): Mark local as initialized.

14593 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14594 New macros, so that the caller can use some names other than
14595 gcpro1, gcpro2, etc.
14596 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14598 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14599 argument, for consistency with GCPRO2_VAR, etc: it is now the
14600 prefix of the variable, not the variable itself. All uses
14602 * dired.c (directory_files_internal, file_name_completion):
14603 Rename locals to avoid shadowing.
14605 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14606 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14607 dired.c's scmp function, had undefined behavior.
14608 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14609 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14610 * buffer.h: ... to here, because these macros use current_buffer,
14611 and the new implementation with inline functions needs to have
14612 current_buffer in scope now, rather than later when the macros
14614 (downcase, upcase1): New static inline functions.
14615 (DOWNCASE, UPCASE1): Reimplement using these functions.
14616 This avoids undefined behavior in expressions like
14617 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14618 from race conditions in accessing the global variables
14619 case_temp1 and case_temp2.
14620 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14621 * lisp.h (case_temp1, case_temp2): Remove their decls.
14622 * character.h (ASCII_CHAR_P): Move from here ...
14623 * lisp.h: ... to here, so that the inline functions mentioned
14624 above can use them.
14626 * dired.c (directory_files_internal_unwind): Now static.
14628 * fileio.c (file_name_as_directory, directory_file_name):
14629 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14631 (file_name_as_directory): Use const pointers when appropriate.
14632 (Fexpand_file_name): Likewise. In particular, newdir might
14633 point at constant storage, so make it a const pointer.
14634 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14635 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14637 (Fset_file_times, Finsert_file_contents, auto_save_error):
14638 Rename locals to avoid shadowing.

14641 (Ftry_completion, Fall_completions): Rename or remove locals
14642 to avoid shadowing.
14644 * marker.c (bytepos_to_charpos): Remove; unused.
14646 * lisp.h (verify_bytepos, count_markers): New decls,
14647 so that gcc does not warn that these functions aren't declared.
14649 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14650 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14651 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14652 (copy_text): Remove unused local var.
14654 * filelock.c (within_one_second): Now static.
14655 (lock_file_1): Rename local to avoid shadowing.
14657 * buffer.c (fix_overlays_before): Mark locals as initialized.
14658 (fix_start_end_in_overlays): Likewise. This function should be
14659 simplified by using pointers-to-pointers, but that's a different
14661 (switch_to_buffer_1): Now static.
14662 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14663 (report_overlay_modification): Rename locals to avoid shadowing.
14665 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14666 Fix pointer signedness issue.
14667 (sys_subshell): Mark local as volatile if checking for lint,
14668 to suppress a gcc -Wclobbered warning that does not seem to be right.
14669 (MAXPATHLEN): Define only if needed.
14671 * process.c (serial_open, serial_configure): Move decls from here ...
14672 * systty.h: ... to here, so that they can be checked.
14674 * fns.c (get_random, seed_random): Move extern decls from here ...
14675 * lisp.h: ... to here, so that they can be checked.
14677 * sysdep.c (reset_io): Now static.
14678 (wait_for_termination_signal): Remove; unused.
14680 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14681 (copy_keymap_item, append_key, push_text_char_description):
14683 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14684 (DENSE_TABLE_SIZE): Remove; unused.
14685 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14686 (describe_map_tree):
14687 Rename locals to avoid shadowing.
14689 * keyboard.c: Declare functions static if they are not used elsewhere.
14690 (echo_char, echo_dash, cmd_error, top_level_2):
14691 (poll_for_input, handle_async_input): Now static.
14692 (read_char, kbd_buffer_get_event, make_lispy_position):
14693 (make_lispy_event, make_lispy_movement, apply_modifiers):
14694 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
14695 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
14696 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
14697 (read_key_sequence, read_char): Mark locals as initialized.

14774 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
14775 These macros can no longer be used for assignment.
14777 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

14833 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
14835 Improve quality of tests for time stamp overflow.
14836 For example, without this patch (encode-time 0 0 0 1 1
14837 1152921504606846976) returns the obviously-bogus value (-948597
14838 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14839 reports time overflow. See
14840 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
14841 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
