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

250 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
251 any, in the DEFALT argument into the root of the Emacs build or
252 installation tree, as appropriate.
254 * callproc.c (init_callproc_1): Call decode_env_path instead of
255 doing its equivalent by hand.
256 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
257 the code that sets Vexec_path run on MS-Windows.
259 * lread.c (init_lread): Add comments to #ifdef's.
261 * msdos.c (dos_set_window_size, IT_update_begin)

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

317 (map_w32_filename): Improve commentary. Simplify switch.
318 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
319 headers (most versions of MinGW w32api don't).
320 (get_security_info, create_symbolic_link)
321 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
323 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
324 in the argument file name.

326 GetFileAttributes fails with network-related error codes.
327 (sys_rename): Diagnose renaming of a symlink when the user doesn't
328 have the required privileges.
329 (get_file_security_desc_by_name): Renamed from
330 get_file_security_desc.
331 (stat_worker): New function, with most of the guts of 'stat', and
332 with addition of handling of symlinks and support for 'lstat'. If
333 possible, get file's attributes and security information by
334 handle, not by name. Produce S_IFLNK bit for symlinks, when
336 (stat, lstat): New functions, call 'stat_worker'.
337 (symlink, readlink, careadlinkat): Rewritten to create and resolve
338 symlinks when the underlying filesystem supports them.
340 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
342 Fix macroexp crash on Windows with debugging (Bug#12118).
343 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
344 checking subscripts; problem introduced with the recent
345 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
346 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
347 since it's used in non-static inline functions now.
349 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
350 Don't assume buffer size fits in 'int'. Remove unused local.
352 Use C99-style 'extern inline' if available.
353 * buffer.h (BUFFER_INLINE):
354 * category.h (CATEGORY_INLINE):

374 are compiled into code.
375 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
376 (INLINE_HEADER_END): New macros.
377 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

401 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
402 This how ASET and AREF are supposed to work, and makes
403 it easier to think about future improvements. See
404 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
405 * charset.h (set_charset_attr): New function.

897 the fix for 12036 would have avoided some of the problems noted in
898 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems

911 not be usable in #if. This simplifies things.
913 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
915 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
917 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

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

1836 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1837 * nsterm.m (ns_term_init):
1838 Avoid the need for strncpy, by using build_string or
1839 make_unibyte_string directly. Use dtoastr, not snprintf.
1840 * process.c (Fmake_network_process): Diagnose service names that
1841 are too long, rather than silently truncating them or creating
1842 non-null-terminated names.
1843 (Fnetwork_interface_info): Likewise, for interface names.
1844 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1845 Prefer sprintf to strncat.
1846 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

1872 Optimize pure C strings initialization.
1873 * lisp.h (make_pure_string): Fix prototype.
1874 (build_pure_c_string): New function, defined as static inline. This
1875 provides a better opportunity to optimize away calls to strlen when
1876 the function is called with compile-time constant argument.
1877 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1878 argument, adjust users accordingly. Use build_pure_c_string where
1880 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1881 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1882 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1884 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1886 Avoid calls to strlen in miscellaneous functions.
1887 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1888 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1889 * lread.c (openp): Likewise.
1891 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1893 Avoid calls to strlen in path processing functions.
1894 * fileio.c (file_name_as_directory): Add comment. Change to add
1895 srclen argument and return the length of result. Adjust users

1909 * s/gnu.h (DATA_START): Move definitions to configure.
1911 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1912 We include usg5-4-common.h, which defines them both.
1914 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1915 O_RDONLY already includes it).
1917 Stop ns builds setting the EMACSLOADPATH environment variable.
1918 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1919 Now it does not set EMACSLOADPATH, just returns the load-path string.
1920 * nsterm.h: Update accordingly.
1921 * lread.c [HAVE_NS]: Include nsterm.h.
1922 (init_lread) [HAVE_NS]: Use ns_load_path.

1925 2012-07-09 Glenn Morris <rgm@gnu.org>
1927 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1928 since the included bsd-common.h does so.
1930 Stop ns builds setting the EMACSPATH environment variable.
1931 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1932 (ns_init_paths): Do not set EMACSPATH.
1933 * nsterm.h (ns_exec_path): Add it.
1934 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1937 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1939 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1941 * process.c (wait_reading_process_output): 'waitchannels' was unset
1942 when read_kbd || !NILP (wait_for_cell); fix this.
1944 Add GCC-style 'const' attribute to functions that can use it.
1945 * character.h (char_resolve_modifier_mask):
1946 * keyboard.h (make_ctrl_char):
1947 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1954 Declare the dummy function with ATTRIBUTE_CONST.
1955 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1956 Add decls with ATTRIBUTE_CONST.
1958 Minor improvements to make_formatted_string.
1959 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1960 where int is good enough, as vsprintf returns an int.
1961 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1963 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1965 Use make_formatted_string to avoid double length calculation.
1966 * lisp.h (make_formatted_string): New prototype.
1967 * alloc.c (make_formatted_string): New function.
1968 * buffer.c (Fgenerate_new_buffer_name): Use it.

1990 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1992 Move marker debugging code under MARKER_DEBUG.
1993 * marker.c (MARKER_DEBUG): Move marker debugging code under
1994 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1995 for bootstrap with --enable-checking (~3x slowdown reported
1996 by Juanma Barranquero <lekktu@gmail.com>).
1997 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1999 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2001 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2002 See <http://bugs.gnu.org/11825#29>.
2004 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2006 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2007 has no font, use the frame's font. (Bug#11813)
2008 (display_line): Add commentary about displaying truncation glyphs
2010 (produce_special_glyphs): Move here from term.c.
2012 * term.c (produce_special_glyphs): Move to xdisp.c.
2014 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2017 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2019 * xdisp.c (display_line): Avoid warning about implicit declaration
2022 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2024 * lisp.h: Remove empty conditional.
2026 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2028 * lread.c (load_path_check): Now static.
2030 Fix some minor --with-ns problems found by static checking.
2031 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2032 (x_set_font) [!HAVE_X_WINDOWS]:
2033 * image.c (xpm_load_image) [HAVE_NS]:
2034 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2035 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2036 Remove unused local.
2037 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2038 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2039 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2040 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2041 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2042 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2043 Fix pointer signedness problem.
2044 * xfaces.c (FRAME_X_FONT_TABLE):
2045 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2047 2012-07-07 Glenn Morris <rgm@gnu.org>
2049 * lread.c (load_path_check): New function, split from init_lread.
2050 (init_lread): Reorganize. Motivation:
2051 If EMACSLOADPATH is set, check/warn about that rather than the
2052 defaults, which we are not going to use. Hence we can remove
2053 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2054 Don't warn if site-lisp directories are missing.
2055 If not installed, start from a blank load-path, since
2056 PATH_LOADSEARCH refers to the eventual installation directories.
2058 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2060 Support truncation and continuation glyphs on GUI frames, when
2061 fringes are disabled. (Bug#11832)
2062 * xdisp.c (init_iterator): Get dimensions of truncation and
2063 continuation glyphs even if on GUI frames. Adjust
2064 it->last_visible_x on GUI frames when the left or right fringes,
2065 or both, are absent.
2066 (start_display, move_it_in_display_line_to): Handle the case of a
2067 GUI frame without a fringe to display continuation or truncation
2069 (insert_left_trunc_glyphs): Support GUI frames: make sure
2070 truncation glyphs overwrite enough glyphs from the current line to
2071 have sufficient space in pixels.
2072 (display_line): Support truncation and continuation glyphs on GUI
2073 frames. If some spare pixels are left on the line after inserting
2074 the truncation glyphs, fill that space with a stretch glyph of a
2075 suitably computed width.
2077 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2078 produce_glyphs, to support GUI sessions.
2080 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2082 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2084 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2086 Do not require float-time's arg to fit in time_t (Bug#11825).
2087 This works better on hosts where time_t is unsigned, and where
2088 float-time is applied to the (negative) difference between two times.
2089 * editfns.c (decode_time_components): Last arg is now double *,
2090 not int *, and means to store all the result as a double, without
2091 worrying about whether the seconds part fits in time_t.
2092 All callers changed.
2093 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2094 All callers changed.
2095 (Ffloat_time): Do not fail merely because the specified time falls
2096 outside of time_t range.
2098 2012-07-07 Glenn Morris <rgm@gnu.org>
2100 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2115 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2116 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2117 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

2120 * xfont.c (compare_font_names): Redo to omit the need for casts.
2122 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2124 * xfns.c (Fx_change_window_property): Doc fix.
2125 * w32fns.c (Fx_change_window_property): Doc fix.
2127 * w32fns.c (Fx_window_property): Accept the same arguments as the
2128 X Windows version. Doc fix.
2129 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2131 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2132 Eli Zaretskii <eliz@gnu.org>
2134 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2135 Windows-specific code from nt/config.nt moved here.
2136 Obsolete settings removed.
2138 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2140 * process.c: Avoid unnecessary calls to gettime.
2141 (wait_reading_process_output): Don't get the time of day
2142 when gobbling data immediately and not waiting, as there's no need
2143 for it in that case. This removes a FIXME.
2145 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2147 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2148 is defined (Bug#11768).

2153 * marker.c (byte_char_debug_check): Do not perform the check
2154 if buffer is not multibyte.
2155 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2156 Call byte_char_debug_check with correct arguments.
2158 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2160 Compile marker debugging code only if ENABLE_CHECKING is defined.
2161 * marker.c (byte_char_debug_check, count_markers):
2162 Use only if ENABLE_CHECKING is defined.
2163 (byte_debug_flag): Remove.
2164 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2165 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2167 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2169 Avoid code repetition in marker-related functions.
2170 * marker.c (attach_marker): New function.
2171 (Fset_marker, set_marker_restricted, set_marker_both)
2172 (set_marker_restricted_both): Use it.
2173 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2174 Consistently rename charno to charpos.
2175 (marker_position): Add eassert.
2176 (marker_byte_position): Convert to eassert.

2195 * window.c (save_window_save): Likewise.
2197 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2199 Do not use Fdelete_overlay in delete_all_overlays
2200 to avoid redundant calls to unchain_overlay.
2201 * buffer.c (drop_overlay): New function.
2202 (delete_all_overlays, Fdelete_overlay): Use it.
2203 * minibuf.c (get_minibuffer): Fix comment.
2205 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2207 Port to OpenBSD 5.1 amd64.
2208 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2209 This is needed for OpenBSD, and should be harmless on all BSD systems.
2210 Also, include <sys/sysctl.h>, as it should be available on all
2211 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2212 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2213 use p_pid member, not kp_proc.pid.
2215 2012-07-06 Glenn Morris <rgm@gnu.org>
2217 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2219 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2221 More xmalloc and related cleanup.
2222 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2223 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2230 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2232 Omit needless casts involving void * pointers and allocation.
2233 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2234 as the former is more robust if P's type is changed.
2235 Prefer xzalloc to xmalloc + memset 0.
2236 Simplify malloc-or-realloc to realloc.
2237 Don't worry about xmalloc returning a null pointer.
2238 Prefer xstrdup to xmalloc + strcpy.
2239 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2241 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2242 alloca of a constant.
2244 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2246 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2247 hscroll is larger than the line width. Fixes long and futile
2248 looping inside extend_face_to_end_of_line (on a TTY) producing
2249 glyphs that are not needed and thrown away.
2251 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2253 * marker.c (set_marker_restricted_both): Simplify by using
2256 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2279 * xdisp.c (window_hscroll_limited): New function.
2280 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2281 coordinates when window's hscroll is set to insanely large
2284 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2286 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2287 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2289 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2292 * lisp.h (xzalloc): New prototype. Omit needless casts.
2293 * alloc.c (xzalloc): New function. Omit needless casts.

2295 xmalloc with following memset to xzalloc.

2347 * fileio.c (time_error_value): Check the right error number.
2348 Problem reported by Troels Nielsen in
2349 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2351 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2353 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2354 This should be fixed in a better way; see Eli Zaretskii in
2355 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2356 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2358 * fileio.c (time_error_value): Rename from special_mtime.
2359 The old name's problems were noted by Eli Zaretskii in
2360 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2362 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2363 This variable's comment says Emacs needs at least one GDB-visible
2364 symbol of type enum pvec_type, to work around GDB problems.
2365 The symbol's value doesn't matter.
2367 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2368 that causes compilation to fail on pre-C99 compilers.
2370 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2372 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2373 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2375 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2377 * buffer.c (init_buffer_once): Fix initialization of
2378 headers for buffer_defaults and buffer_local_symbols.
2379 Reported by Juanma Barranquero <lekktu@gmail.com>.
2381 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2383 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2384 * lisp.h (enum pvec_type): Use fewer bits.
2385 (PSEUDOVECTOR_SIZE_BITS): New constant.
2386 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2387 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2388 change in pvec_type.
2389 (PSEUDOVECTOR_TYPEP): New macro.
2390 (TYPED_PSEUDOVECTORP): Use it.
2391 * fns.c (internal_equal): Adapt code to extract pvectype.
2392 * emacs.c (gdb_pvec_type): Update type.
2393 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2394 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2395 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2396 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2397 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2398 abusing vector->header.next.nbytes.
2399 (live_vector_p): Use PVEC_TYPE.
2400 (mark_object): Adapt code to extract pvectype. Use switch.
2402 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2404 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2405 Tighten new eassert a bit.
2407 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2409 Fix compilation with --enable-gcc-warnings and -O1
2411 * doprnt.c (doprnt): Change type of tem to int, initialize
2412 to avoid compiler warning. Add eassert.
2413 * search.c (simple_search): Initialize match_byte to avoid
2414 compiler warning. Add eassert.
2416 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2418 Avoid weird behavior with large horizontal scrolls.
2419 Without this change, for example, large hscroll values would
2420 mess up Emacs's display on Fedora 15 x86, presumably due to
2421 overflows in int calculations in the display code.
2422 Also, if buffers had long lines, Emacs would freeze.
2423 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2424 (set_window_hscroll): New function, containing the old guts of
2425 Fset_window_hscroll. Return the clipped value.
2426 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2427 This avoids the need to check against PTRDIFF_MAX.
2429 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2431 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2433 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2435 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2437 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2438 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2439 since GCC 4.4.6 issues a bogus warning for them.
2441 Fix bugs in file timestamp newness comparisons.
2442 * fileio.c (Ffile_newer_than_file_p):
2443 * lread.c (Fload): Use full timestamp resolution of files,
2444 not just the 1-second resolution, so that files that are only
2445 slightly newer still count as newer.
2446 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2447 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2449 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2451 * fileio.c: Improve handling of file time marker. (Bug#11852)
2452 (special_mtime): New function.
2453 (Finsert_file_contents, Fverify_visited_file_modtime):
2454 Use it to set special mtime values consistently.
2456 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2458 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2459 marker for non-existing file. (Bug#11852)
2461 2012-07-03 Glenn Morris <rgm@gnu.org>
2463 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2464 and did not make it into globals.h).
2466 2012-07-03 Tom Tromey <tromey@redhat.com>
2468 * window.c (Fset_window_margins, Fset_window_fringes)
2469 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2470 * textprop.c (Fprevious_property_change): No longer static.
2471 * syntax.c (Fsyntax_table_p): No longer static.
2472 * process.c (Fget_process, Fprocess_datagram_address): No longer

2492 * dispextern.h: Remove EXFUNs.
2493 * intervals.h: Remove EXFUNs.
2494 * fontset.h: Remove EXFUN.
2495 * font.h: Remove EXFUNs.
2496 * dosfns.c (system_process_attributes): Remove EXFUN.

2499 * w32term.h: Remove EXFUNs.
2500 * window.h: Remove EXFUNs.
2501 * xsettings.h: Remove EXFUN.
2502 * xterm.h: Remove EXFUN.
2504 2012-07-03 Glenn Morris <rgm@gnu.org>
2506 * lisp.h (Frandom): Make it visible to C.
2507 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2508 buffer for invisible buffers. (Bug#1229)
2510 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2512 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2513 values which aren't power of 2.
2514 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2515 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2518 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2520 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2522 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2524 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2526 * alloc.c (allocate_vector_block): Remove redundant
2527 calls to mallopt if DOUG_LEA_MALLOC is defined.
2528 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2529 avoid calls to mallopt if zero_vector is returned.
2531 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2533 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2534 is enabled, avoid dereferencing NULL current_sblock if
2537 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2539 Cleanup basic buffer management.
2540 * buffer.h (struct buffer): Change layout to use generic vector
2541 marking code. Fix some comments. Change type of 'clip_changed'
2542 to bitfield. Remove unused #ifndef old.
2543 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2544 (GET_OVERLAYS_AT): Fix indentation.
2545 (for_each_per_buffer_object_at): New macro.
2546 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2549 * alloc.c (allocate_buffer): Adjust to match new layout of
2550 struct buffer. Fix comment.
2551 (mark_overlay): New function.

2554 (mark_object): Use it. Adjust marking of misc objects
2555 and related comments.
2557 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2559 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2560 wrapper that is not needed because the wrapped code is a no-op (zero
2561 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2562 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2564 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2566 * alloc.c (mark_buffer): Simplify. Remove prototype.
2567 (mark_object): Add comment. Reorganize marking of vector-like
2568 objects. Use CHECK_LIVE for all vector-like objects except buffers
2569 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2570 redundant calls to mark_vectorlike for bool vectors.
2572 2012-06-30 Glenn Morris <rgm@gnu.org>
2574 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2576 * epaths.in (PATH_SITELOADSEARCH): New.
2577 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2578 This is rather than relying on --enable-locallisppath elements
2579 having "site-lisp" in their names. (Bug#10208#25, 11658)
2581 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2583 * w32proc.c (sys_select): Accept and ignore one more argument.
2585 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2587 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2588 (pselect) [!MS_DOS]: Redirect to sys_select.
2590 * sysdep.c: Don't include dos.h and dosfns.h.
2592 * process.c (sys_select):
2593 * msdos.c (sys_select): Accept one more argument and ignore it.
2595 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2596 adapt data types and code to that.
2599 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2600 which clashes with the gnulib function of the same name.
2602 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2604 * font.c (font_style_to_value, font_style_symbolic)
2605 (font_prop_validate_style): Add type checks for values in
2608 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2610 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2613 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2615 * xdisp.c (try_window_id): Undo last change.
2617 * w32.c (getwd): Adjust commentary about startup_dir.
2618 (init_environment): Always call sys_access, even in non-MSVC
2619 builds. Don't chdir to the directory of the Emacs executable.
2620 This undoes code from 1997 which was justified by the need to
2621 "avoid conflicts when removing and renaming directories". But its
2622 downside was that every relative file name was being interpreted
2623 relative to the directory of the Emacs executable, which can never
2624 be TRT. In particular, it broke sys_access when called with
2625 relative file names.
2626 (sys_access): Map GetLastError to errno.
2628 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2630 * window.h (struct window): Change type of 'fringes_outside_margins'

2634 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2637 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2639 * gnutls.c (emacs_gnutls_handshake):
2640 Add QUIT to make the loop interruptible.
2642 2012-06-29 Glenn Morris <rgm@gnu.org>
2644 * charset.c (init_charset): Make lack of etc/charsets fatal.
2646 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2648 * editfns.c (region_limit): Fix type mismatch.
2650 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2652 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2653 undefined. Convert from xassert to eassert.
2654 * nsmenu.m: Convert from xassert to eassert.
2655 * nsterm.m: Likewise.
2657 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2659 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2661 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2663 Avoid integer overflow on scroll-left and scroll-right.
2664 * window.c (HSCROLL_MAX): New macro.
2665 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2666 overflow when requested scroll falls outside ptrdiff_t range.
2668 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2670 * window.h (struct window): Change type of 'hscroll',
2671 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2672 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2673 Adjust users accordingly.
2674 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2675 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2676 from EMACS_INT to ptrdiff_t.
2677 (make_window): Omit redundant initialization.
2679 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2681 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2683 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2685 * window.h (struct window): Change type of 'use_time' and
2686 'sequence_number' from Lisp_Object to int.
2687 * frame.c (make_frame): Adjust users accordingly.

2695 enabled with --enable-checking=[all,glyphs] configure option.
2696 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2697 adjust comments accordingly.

2748 avoid GCC warning about unused macro.
2750 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2752 * alloc.c (allocate_string): Omit intervals initialization.
2753 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2754 as in make_pure_string and make_pure_c_string.
2756 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2758 * alloc.c (allocate_string): Fix last change.
2760 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2783 * eval.c (Fapply): Allow calling it with a single argument.
2785 2012-06-26 Eli Zaretskii <eliz@gnu.org>

2810 * alloc.c: Remove build_string.
2811 * lisp.h: Define build_string as static inline. This provides
2812 a better opportunity to optimize away calls to strlen when the
2813 function is called with compile-time constant argument.
2814 * image.c (imagemagick_error): Convert to build_string.
2815 * w32proc.c (sys_spawnve): Likewise.
2816 * xterm.c (x_term_init): Likewise.
2818 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2820 Use sprintf return value instead of invoking strlen on result.
2821 In the old days this wasn't portable, since some sprintf
2822 implementations returned char *. But they died out years ago and
2823 Emacs already assumes sprintf returns int.
2824 Similarly for float_to_string.
2825 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2826 * ccl.c (ccl_driver):
2827 * character.c (string_escape_byte8):

2830 * print.c (print_object):
2831 * xdisp.c (message_dolog):
2832 * xfns.c (syms_of_xfns):
2833 Use sprintf or float_to_string result to avoid need to call strlen.
2834 * data.c (Fnumber_to_string):
2835 Use make_unibyte_string, since the string must be ASCII.
2836 * lisp.h, print.c (float_to_string): Now returns int length.
2837 * term.c (produce_glyphless_glyph):
2838 Use sprintf result rather than recomputing it.
2840 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2841 * Makefile.in (ALL_CFLAGS):
2842 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
2843 * gmalloc.c, regex.c: Include <config.h> unconditionally.
2845 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2847 * dispextern.h (xstrcasecmp): Define to library function
2848 strcasecmp if available.
2849 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
2851 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

2864 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
2866 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2867 sprintf already null-terminates its output.
2869 * xfns.c (x_window): Remove redundant cast.
2871 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2873 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2874 `const char *' to `char *' to avoid compiler warning.
2876 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2878 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2879 instead of truncating it to 63 (admittedly a generous limit).
2881 * process.c: Fix spelling and caps in comments.
2883 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2885 * emacs.c (setpgrp): Remove definition, unused.

2929 Use _Noreturn rather than NO_RETURN.
2930 No need for separate decl merely because of _Noreturn.
2931 * sound.c (sound_warning, parse_sound):
2932 Remove unnecessary forward decls.
2934 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2936 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
2937 * lisp.h (WAIT_READING_MAX): New macro.
2938 * dispnew.c (Fsleep_for, sit_for):
2939 * keyboard.c (kbd_buffer_get_event):
2940 * process.c (Faccept_process_output):
2941 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2942 This improves on the previous patch, which introduced a bug
2943 when time_t is unsigned and as wide as intmax_t.
2944 See <http://bugs.gnu.org/9000#51>.
2946 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2948 * dispnew.c (sit_for, Fsleep_for):
2949 * keyboard.c (kbd_buffer_get_event):

2962 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2963 Privately reported by Herbert J. Skuhra.
2964 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2966 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2967 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2969 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2971 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
2972 last argument of make_unibyte_string.
2974 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
2975 language ID in the event parameters.
2977 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2978 event.code, not the obscure "character set ID".
2980 2012-06-23 Chong Yidong <cyd@gnu.org>
2982 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
2984 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2986 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

3001 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
3002 Privately reported by Herbert J. Skuhra.
3003 [__FreeBSD__]: Remove "*/" typo after "#include".
3004 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
3005 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
3006 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
3007 Don't assume EMACS_TIME and struct timeval are the same type.
3009 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3011 Support higher-resolution time stamps (Bug#9000).
3012 The time stamps are only nanosecond-resolution at the C level,
3013 since that's the best that any real-world system supports now.
3014 But they are picosecond-resolution at the Lisp level, as that's
3015 easy, and leaves room for future OS improvements.
3017 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3020 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3021 Don't get current time unless it's needed.
3023 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3024 now provides it if it's absent.
3025 (start_atimer): Port to higher-res time stamps.
3026 Check for time stamp overflow. Don't get current time more
3027 often than is needed.
3029 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3030 Include systime.h, not time.h.
3031 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3033 * dired.c: Include stat-time.h.
3034 (Ffile-attributes): File times now have higher resolution.
3036 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3037 (struct image): Timestamp now has higher resolution.
3039 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3040 has at least microseconds now. All uses removed.
3041 (update_frame, update_single_window, update_window, update_frame_1)
3042 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3044 * editfns.c (time_overflow): Now extern.
3045 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3046 (float-time, Fformat_time_string, Fcurrent_time_string)
3047 (Fcurrent_time_zone): Accept and generate higher-resolution
3049 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3050 (decode_time_components, lisp_seconds_argument): New functions.
3051 (make_time): Now static.
3052 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3053 Report an error if the time is invalid, rather than having the caller
3056 * fileio.c: Include <stat-time.h>
3057 (Fcopy_file): Copy higher-resolution time stamps.
3058 Prefer to set the time stamp via a file descriptor if that works.
3059 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3060 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3061 (Fvisited_file_modtime, Fset_visited_file_modtime):
3062 Support higher-resolution time stamps.
3064 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3066 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3068 * image.c (prepare_image_for_display, clear_image_cache)
3069 (lookup_image): Port to higer-resolution time stamps.
3071 * keyboard.c (start_polling, bind_polling_period):
3072 Check for time stamp overflow.
3073 (read_char, kbd_buffer_get_event, timer_start_idle)
3074 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3075 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3076 Port to higher-resolution time stamps. Do not assume time_t is signed.
3077 (decode_timer): New function. Timers are now vectors of length 9,
3078 not 8, to accommodate the picosecond component.
3079 (timer_check_2): Use it.
3081 * nsterm.m (select_timeout, timeval_subtract): Remove.
3082 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3083 as they're a bit more accurate and handle overflow better.
3084 (ns_select): Change prototype to be compatible with pselect.
3085 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3086 * nsterm.h (ns_select): Adjust prototype.
3088 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3089 us-resolution time stamps.
3090 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3092 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3094 * lisp.h (time_overflow): New decl.
3095 (wait_reading_process_output): First arg is now intmax_t, not int,
3096 to accommodate larger waits.
3098 * process.h (struct Lisp_Process.read_output_delay):
3099 Now counts nanoseconds, not microseconds.
3100 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3102 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3103 (wait_reading_process_output):
3104 Port to ns-resolution time stamps.
3105 (Faccept_process_output, wait_reading_process_output):
3106 Check for time stamp overflow. Do not assume time_t is signed.
3107 (select_wrapper): Remove; we now use pselect.
3108 (Fprocess_attributes): Now generates ns-resolution time stamps.
3110 * sysdep.c: Include utimens.h. Don't include utime.h
3111 or worry about struct utimbuf; gnulib does that for us now.
3112 (gettimeofday): Remove; gnulib provides a substitute.
3113 (make_timeval): New function.
3114 (set_file_times): Now sets ns-resolution time stamps.
3115 New arg FD; all uses changed.
3116 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3117 (system_process_attributes):
3118 Now returns ns-resolution time stamp. All uses changed.
3119 Check for time stamp overflow.
3121 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3122 provides a substitute now.
3124 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3125 since it guarantees struct timespec.
3126 (EMACS_TIME): Now struct timespec, so that we can support
3127 ns-resolution time stamps.
3128 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3129 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3130 (EMACS_USECS): Remove.
3131 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3132 so multiply the arg by 1000 before storing it.
3133 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3135 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3136 Port to ns-resolution time stamps.
3137 (EMACS_TIME_NEG_P): Remove; replaced by....
3138 (EMACS_TIME_SIGN): New macro.
3139 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3140 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

3142 (make_timeval, make_lisp_time, decode_time_components): New decls.
3143 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3144 that it mishandled time_t overflow. You can't compare by subtracting!
3145 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3146 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3148 * term.c: Include <sys/time.h>.
3149 (timeval_to_Time): New function, for proper overflow wraparound.
3150 (term_mouse_position, term_mouse_click): Use it.

3154 (Fprimitive_undo): Use them when restoring time stamps.
3156 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3157 (w32_get_internal_run_time):
3158 Port to higher-resolution Emacs time stamps.
3159 (ltime): Now accepts single 64-bit integer, as that's more convenient
3162 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3164 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3165 for compatibility with pselect. Support ns-resolution time stamps.
3167 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3169 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3170 Check for time stamp overflow, and support ns-resolution time stamps.
3172 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3173 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3174 (timeval_subtract): Remove; no longer needed.
3175 (XTflash, XTring_bell, x_wait_for_event):
3176 Port to ns-resolution time stamps. Don't assume time_t is signed.
3178 2012-06-22 Chong Yidong <cyd@gnu.org>
3180 * xdisp.c (x_consider_frame_title): Revert last change.
3182 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3184 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3185 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3186 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3187 staticidx goes up to 1597 out of 1600 = 0x640.)
3189 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3191 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3192 Otherwise, the umask might be mistakenly 0 while handling input signals.
3194 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3196 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
3198 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
3200 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
3201 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
3202 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3203 access to `contents' member of Lisp_Vector objects with AREF and ASET
3206 2012-06-19 Chong Yidong <cyd@gnu.org>
3208 * frame.c (delete_frame): When selecting a frame on a different
3209 text terminal, do not alter the terminal's top-frame.

3212 frame's selected window and its terminal's top-frame.
3213 (unwind_format_mode_line): Restore them.
3214 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3216 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3217 since tty frames can be explicitly named.
3218 (prepare_menu_bars): Likewise.
3220 * term.c (Ftty_top_frame): New function.
3222 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3224 Port byte-code-meter to modern targets.
3225 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3226 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3227 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3228 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3229 (METER_1, METER_2): Simplify.
3231 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3233 * data.c (Fdefalias): Return `symbol' (bug#11686).
3235 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3237 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3238 gets killed during executing of this function (Bug#11665).
3239 Try to always return Qt when the buffer has been actually killed.
3240 (Vkill_buffer_query_functions): In doc-string say that functions

3461 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3462 Use an inline function on all platforms when using the union type,
3463 since this is simpler and 'static inline' can be used portably

3607 * doprnt.c (doprnt): Truncate multibyte char correctly.
3608 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3609 would mishandle a string argument "Xc" if X was a multibyte

3694 and 'double' in a couple of places.

3698 * xdisp.c (handle_stop): Detect whether we have overlay strings
3699 loaded by testing it->current.overlay_string_index to be
3700 non-negative, instead of checking whether n_overlay_strings is
3701 positive. (Bug#11587)

3718 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3719 for the duration of call to load_charset, to avoid problems with
3720 callers of maybe_unify_char that access buffer text through C

3724 decrement the inhibition flag, instead of just setting or
3727 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3729 Remove obsolete '#define static' cruft.
3730 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3731 This #undef was "temporary" in 2000; it is no longer needed
3732 now that '#define static' has gone away.
3733 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3734 (gray_bitmap_bits): Remove; no longer needed.
3735 All uses replaced with definiens.
3736 * xterm.c: Include "bitmaps/gray.xbm".
3738 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3740 Clean up __executable_start, monstartup when --enable-profiling.
3741 The following changes affect the code only when profiling.
3742 * dispnew.c (__executable_start): Rename from safe_bcopy.
3743 Define only on platforms that need it.
3744 * emacs.c: Include <sys/gmon.h> when profiling.
3745 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3746 (__executable_start): Remove decl, since lisp.h does it now.
3747 (safe_bcopy): Remove decl; no longer has that name.
3748 (main): Coalesce #if into single bit of code, for simplicity.
3749 Cast pointers to uintptr_t, since standard libraries want integers
3751 * lisp.h (__executable_start): New decl.
3753 2012-05-31 Glenn Morris <rgm@gnu.org>
3755 * image.c (Fimagemagick_types): Doc fix.

3774 * lread.c (read1): Tiny simplification.
3776 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3778 Do not create empty overlays with the evaporate property (Bug#9642).
3779 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3780 Bug#9642, but explicitly check that the buffer the overlay would
3781 be moved to is live and rearrange lines to make sure that errors
3782 will not put the overlay in an inconsistent state.
3783 (Fdelete_overlay): Cosmetics.
3785 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3787 * w32term.c (my_bring_window_to_top): New function.
3788 (x_raise_frame): Use handle returned by DeferWindowPos, which
3789 could be different from the original one.

3793 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3794 by calling BringWindowToTop.
3796 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3797 (WM_EMACS_END): Increase by one.
3799 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3801 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3802 This avoids undefined behavior that might cause the eassert
3803 to not catch an out-of-range value.
3805 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3807 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3808 Update dependencies.
3810 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3812 * bidi.c (bidi_mirror_char): Fix last change.
3814 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3816 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3817 when referring to sectname field in printf format.
3819 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3821 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3822 Only r_alloc_inhibit_buffer_relocation needed to be added;
3823 the others were already declared.
3825 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3826 before checking whether it's out of range. Put the check inside
3828 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3830 2012-05-27 Ken Brown <kbrown@cornell.edu>
3832 * callproc.c (Fcall_process): Restore a line that was accidentally
3833 commented out in the 2011-02-13 change (bug#11547).
3835 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3837 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3838 defined on ralloc.c.
3840 * buffer.c [REL_ALLOC]: Remove prototypes of
3841 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3842 they are now on lisp.h.
3844 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3846 * search.c (search_buffer): Use it to inhibit relocation of buffer
3847 text while re_search_2 is doing its job, because re_search_2 is
3848 passed C pointers to buffer text. (Bug#11519)
3850 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3853 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3854 state after an additional call to move_it_in_display_line_to, keep
3855 the values of it->max_ascent and it->max_descent found for the
3857 (pos_visible_p): Revert the comparison against bottom_y to what it
3858 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3861 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3863 Fix coding-related core dumps with gcc -ftrapv.
3864 The code was computing A - B, where A and B are pointers, and B is
3865 random garbage. This can lead to core dumps on platforms that
3866 have special pointer registers, and it also leads to core dumps on
3867 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3868 A - B only when B is initialized properly.
3869 * coding.c (coding_set_source, coding_set_destination): Return void.
3870 (coding_change_source, coding_change_destinations): New functions,
3871 with the old behaviors of coding_set_source and coding_set_destination.
3872 All callers that need an offset changed to use these new functions.
3874 2012-05-26 Glenn Morris <rgm@gnu.org>
3876 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3878 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3880 Extend mouse support on W32 text-mode console.
3881 * xdisp.c (draw_row_with_mouse_face):
3882 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3884 * w32console.c: Include window.h.
3885 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3887 (initialize_w32_display): Initialize mouse-highlight data.
3889 * w32inevt.c: Include termchar.h and window.h.
3890 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3891 moves, call note_mouse_highlight. If help_echo changed, call
3892 gen_help_event to produce help-echo message in the echo area.
3893 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3896 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3898 * lread.c (read1): Simplify slightly to avoid an overflow warning
3899 with GCC 4.7.0 on x86-64.
3901 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3903 * bidi.c (bidi_mirror_char): Revert last change: an int is
3904 definitely wide enough here.
3906 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3908 Fix integer width and related bugs (Bug#9874).
3909 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):

3916 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3918 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3919 (allocate_pseudovector):
3920 Use int, not EMACS_INT, where int is wide enough.
3921 (inhibit_garbage_collection, Fgarbage_collect):
3922 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3923 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3924 int might not be wide enough.
3925 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3926 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

3928 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3929 (bidi_level_of_next_char, bidi_move_to_visually_next):
3930 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3931 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3932 (Fkill_buffer, Fset_buffer_major_mode)

3936 (overlay_strings, recenter_overlay_lists)
3937 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3938 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3939 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3940 (Foverlay_recenter, last_overlay_modification_hooks_used)
3941 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3942 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3943 (validate_region): Omit unnecessary test for b <= e,
3944 since that's guaranteed by the previous test.
3945 (adjust_overlays_for_delete): Avoid pos + length overflow.
3946 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3947 (report_overlay_modification):
3948 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3949 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3950 Omit pointer cast, which isn't needed anyway, and doesn't work
3951 after the EMACS_INT -> ptrdiff_t change.
3952 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3953 * buffer.h: Adjust decls to match defn changes elsewhere.

3957 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3958 not int, to avoid needless 32-bit limit on 64-bit hosts.
3959 (exec_byte_code): Use tighter memory-full test, one that checks
3960 for alloca overflow. Don't compute the address of the object just
3961 before an array, as that's not portable. Use EMACS_INT, not
3962 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3963 * callint.c (Fcall_interactively):
3964 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3965 * callproc.c (call_process_kill, Fcall_process):
3966 Don't assume pid_t fits into an Emacs fixnum.

3975 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3976 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3977 (casify_object): Avoid integer overflow when overallocating buffer.
3978 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3979 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3980 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3981 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3982 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3983 integers are now checked earlier. All uses replaced with XINT.
3985 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3986 For CCL_MapSingle, check that content and value are in int range.
3987 (ccl_driver, Fregister_code_conversion_map):
3988 Check that Vcode_version_map_vector is a vector.
3989 (resolve_symbol_ccl_program): Check that vector header is in range.
3990 Always copy the vector, so that we can check its contents reliably
3991 now rather than having to recheck each instruction as it's being
3992 executed. Check that vector words fit in 'int'.
3993 (ccl_get_compiled_code, Fregister_ccl_program)
3994 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3995 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3996 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3997 contents are in range.
3998 (Fccl_execute_on_string): Check that status is in range.
3999 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4000 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4001 Accept and return EMACS_INT, not int, because callers can pass values
4003 (c_string_width, strwidth, lisp_string_width, chars_in_text)

4006 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4007 (string_escape_byte8, Fget_byte):
4008 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4009 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4010 avoid mishandling large integers.
4011 * character.h: Adjust decls to match defn changes elsewhere.

4020 (Fdefine_charset_internal): Check ranges here, more carefully.
4021 Don't rely on undefined behavior with signed left shift overflow.
4022 Don't assume unsigned int fits into fixnum, or that fixnum fits
4023 into unsigned int. Don't require max_code to be a valid fixnum;
4024 that's not true for gb10830 4-byte on a 32-bit host. Allow
4025 invalid_code to be a cons, for the same reason. Require code_offset
4026 to be a character. Avoid int overflow if max_char is close
4028 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4029 this is intended anyway and avoids some undefined behavior.
4030 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4031 INDEX_TO_CODE_POINT, as that's what it expects.
4032 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4033 * charset.h (DECODE_CHAR): Return int, not unsigned;
4034 this is what was intended anyway, and it avoids undefined behavior.
4035 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4036 integer-overflow issues.
4037 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4038 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4039 where the argument is EMACS_INT, and this behavior is not intended.
4040 * chartab.c (Fmake_char_table, Fset_char_table_range)
4041 (uniprop_get_decoder, uniprop_get_encoder):
4042 Don't assume fixnum fits in int.
4043 * cmds.c (move_point): New function, that does the gist of
4044 Fforward_char and Fbackward_char, but does so while checking
4045 for integer overflow more accurately.
4046 (Fforward_char, Fbackward_char): Use it.
4047 (Fforward_line, Fend_of_line, internal_self_insert)
4048 (internal_self_insert):
4049 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4050 Fix a FIXME, by checking for integer overflow when calculating
4051 target_clm and actual_clm.

4086 Don't access memory outside of the args array.
4087 (Fdefine_coding_system_internal): Check for charset-id overflow.
4088 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4089 result of ENCODE_CHAR.

4107 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4108 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
4109 Do not attempt to compute the address of the object just before a
4110 buffer; this is not portable.
4112 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4113 (Faset): Use int, not EMACS_INT, where int is wide enough.
4114 (Fstring_to_number): Don't assume fixnums fit in int.

4855 and there's something on it->stack, call set_iterator_to_next to
4856 proceed with what's on the stack, instead of returning zero.
4857 (set_iterator_to_next): If called at the end of a Lisp string,
4858 proceed to consider_string_end without incrementing string
4859 position. Don't increment display vector index past the end of
4860 the display vector. (Bug#11417)
4861 (pos_visible_p): Don't report a position visible when move_it_to
4862 stopped at the last line of window, which happens to be scanned
4863 backwards by the bidi iteration. (Bug#11464)
4865 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4867 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4868 and right-margin display specs even if the spec is invalid or we
4869 are on a TTY, and thus unable to display on the fringes.
4870 That's because the text with the property will not be displayed anyway,
4871 so we need to signal to the caller that this is a "replacing"
4872 display spec. This fixes display when the spec is invalid or we
4875 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4877 * unexaix.c (make_hdr): Fix typo in prototype.
4878 This bug broke the build on AIX. Problem reported by Gilles Pion.
4880 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4882 * keyboard.c (kbd_buffer_get_event): Read special events also in
4883 batch mode. (Bug#11415)
4885 2012-05-12 Glenn Morris <rgm@gnu.org>
4887 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4889 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4891 * lisp.mk (lisp): Add newcomment.elc.
4893 2012-05-12 Glenn Morris <rgm@gnu.org>
4895 * Makefile.in (MKDIR_P): New, set by configure.
4896 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4898 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4900 Remove unused function hourglass_started.
4901 * dispextern.h (hourglass_started):
4902 * w32fns.c (hourglass_started):
4903 * xdisp.c (hourglass_started): Remove.
4905 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4907 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4908 Update dependencies.
4910 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4912 * xgselect.c (xg_select): Put maxfds+1 into a var.
4913 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4915 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4917 2012-05-10 Dave Abrahams <dave@boostpro.com>
4919 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4920 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4922 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4924 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4925 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4926 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4927 Initialize xd_registered_buses.
4929 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4931 Untag more efficiently if USE_LSB_TAG.
4932 This is based on a proposal by YAMAMOTO Mitsuharu in
4933 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4934 For an admittedly artificial (nth 8000 longlist) benchmark on
4935 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4936 Emacs's overall text size by 1%.
4937 * lisp.h (XUNTAG): New macro.
4938 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4939 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4940 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4941 * eval.c (Fautoload):
4942 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4943 * frame.h (XFRAME): Use XUNTAG.
4945 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4946 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4947 Remove unportable assumptions about print widths of types like
4949 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4950 intptr_t when converting between pointer and integer, to avoid GCC
4951 warnings about wrong width.
4953 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4955 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4956 stack for each reader_thread, instead of defaulting to 8MB
4957 determined by the linker. This avoids failures in creating
4958 subprocesses on Windows 7, see the discussion in this thread:
4959 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4961 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4963 Fix up display of the *Minibuf-0* buffer in the mini window.
4964 * keyboard.c (read_char): Don't clear the echo area if there's no
4966 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4967 contents of *Minibuf-0*) if there's no message displayed in its stead.
4969 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4971 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4974 2012-05-06 Chong Yidong <cyd@gnu.org>
4976 * lisp.mk (lisp): Update.
4978 2012-05-05 Jim Meyering <meyering@redhat.com>
4980 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4982 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4984 * data.c (PUT_ERROR): New macro.
4985 (syms_of_data): Use it. Add new error type `user-error'.
4986 * undo.c (user_error): New function.
4987 (Fprimitive_undo): Use it.
4988 * print.c (print_error_message): Adjust print style for `user-error'.
4989 * keyboard.c (user_error): New function.
4990 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4992 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4994 Do not limit current-time-string to years 1000..9999.
4995 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4996 (Fcurrent_time_string): Support any year that is supported by the
4997 underlying localtime representation. Don't use asctime, as it
4998 has undefined behavior for years outside the range -999..9999.
5000 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5002 Fix race conditions involving setenv, gmtime, localtime, asctime.
5003 Without this fix, interrupts could mess up code that uses these
5004 nonreentrant functions, since setting TZ invalidates existing
5005 tm_zone or tzname values, and since most of these functions return
5006 pointers to static storage.
5007 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5008 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5009 Grow the critical sections to include not just invoking
5010 localtime/gmtime, but also accessing these functions' results
5011 including their tm_zone values if any, and any related TZ setting.
5012 (format_time_string): Last arg is now struct tm *, not struct tm **,
5013 so that the struct tm is saved in the critical section.
5014 All callers changed. Simplify allocation of initial buffer, partly
5015 motivated by the fact that memory allocation needs to be outside
5016 the critical section.
5018 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5020 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5021 with RESET_INTERVAL.
5023 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5024 Remove duplicated buffer name initialization.
5026 2012-05-02 Jim Meyering <jim@meyering.net>
5028 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5030 * xfns.c (x_window): Use xstrdup (Bug#11375).
5032 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5034 * xdisp.c (pos_visible_p): If already at a newline from the
5035 display string before the 'while' loop, don't walk back the glyphs
5036 from it3.glyph_row. Solves assertion violation when the display
5037 string begins with a newline (egg.el). (Bug#11367)
5039 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5041 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5044 2012-05-01 Glenn Morris <rgm@gnu.org>
5046 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5047 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5048 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5049 All were removed before 23.1.
5051 * dispnew.c: Remove HAVE_LIBNCURSES test;
5052 it is always true on relevant platforms.
5054 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5055 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5057 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5059 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5061 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5062 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5065 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5067 Do not avoid creating empty evaporating overlays (Bug#9642).
5068 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5069 That is, do not delete an evaporating overlay if it becomes
5070 empty after its bounds are adjusted to fit within its buffer.
5071 This fix caused other problems, and I'm reverting it until we get
5072 to the bottom of them.
5074 2012-04-27 Chong Yidong <cyd@gnu.org>
5076 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5078 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5080 * xdisp.c (pos_visible_p): If the window start position is beyond
5081 ZV, start the display from buffer beginning. Prevents assertion
5082 violation in init_iterator when the minibuffer window is scrolled
5085 * window.c (window_scroll_pixel_based): Likewise.
5087 2012-04-27 Chong Yidong <cyd@gnu.org>
5089 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5091 2012-04-27 Glenn Morris <rgm@gnu.org>
5093 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5094 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5096 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5098 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5099 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5101 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5103 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5104 display element, check also the underlying string or buffer
5105 character. (Bug#11341)
5107 * w32menu.c: Include w32heap.h.
5108 (add_menu_item): If the call to AppendMenuW (via
5109 unicode_append_menu) fails, disable Unicode menus only if we are
5110 running on Windows 9X/Me.
5112 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5114 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5115 (xgetint): Add missing shift for LSB tags.
5117 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5119 * keyboard.c (read_char): Don't wipe echo area for select window
5120 events: These might get delayed via `mouse-autoselect-window'
5123 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5125 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5126 manipulation of :loaded-from data.
5128 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5130 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5131 now a cons (bug#11311).
5133 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5135 Do not create empty overlays with the evaporate property (Bug#9642).
5136 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5137 if it becomes empty after its bounds are adjusted to fit within
5138 its buffer. Without this fix, in a nonempty buffer (let ((o
5139 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5140 yields an empty overlay that has the evaporate property, which is
5141 not supposed to happen.
5143 Fix minor GTK3 problems found by static checking.
5144 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5145 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5146 (struct _EmacsFixedClass, emacs_fixed_get_type):

5154 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5155 (EMACS_FIXED_GET_CLASS): Remove; unused.
5156 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5158 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5159 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5161 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5163 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5164 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5165 (__malloc_size_t, __malloc_ptrdiff_t):
5166 Remove. All uses removed, replaced by the definiens if needed,
5167 since we can assume C89 or better now.
5168 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5169 (protect_malloc_state, align, get_contiguous_space)
5170 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5176 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5177 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5178 Define using prototypes, not old style.
5179 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5180 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5181 (align): Don't assume that signed integer overflow wraps around.
5182 Omit unused local var.
5183 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5184 (_free_internal_nolock, memalign, mallochook, reallochook):
5185 Omit no-longer-needed casts.

5188 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5190 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5192 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

5237 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5239 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
5240 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
5241 Do not assume ptrdiff_t is the same width as 'int'.
5243 * alloc.c: Handle unusual debugging option combinations.
5244 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5245 since the two debugging options are incompatible.
5246 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

5249 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5256 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5258 * sysdep.c [__FreeBSD__]: Minor cleanups.
5259 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5260 Use Emacs indenting style more consistently. Avoid some casts.
5261 Use 'double' consistently rather than mixing 'float' and 'double'.
5263 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5265 * sysdep.c (list_system_processes, system_process_attributes):

5300 row, return zero immediately.
5301 (try_cursor_movement): If inside continuation line, don't back up
5302 farther than the first row after the header line, if any.
5303 Don't consider the header-line row as "partially visible", even if
5304 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

5320 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
5321 -Wunused-result, -Wunused-variable. This should go away once
5322 the Emacs and Gnulib regex code is merged.

5341 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5342 New extern decls, to avoid calling undeclared functions.
5343 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5344 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5345 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5346 (NEED_MEM_INSERT): New macro.
5347 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5348 Remove one incorrect comment and fix another.

5354 (r_alloc_sbrk): Now static.
5356 Improve ralloc.c interface checking.
5357 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

5361 [REL_ALLOC]: ... to here, to check interface.
5362 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5363 Remove decls. This fixes an "It stinks!".
5365 * alloc.c (which_symbols): Fix alignment issue / type clash.
5367 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5369 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5370 (struct Lisp_Misc_Any): Likewise.

5382 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5383 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5384 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5385 * s/netbsd.h, s/sol2-6.h:
5386 Remove definition of GC_MARK_STACK, since the default now works.
5387 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5388 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5389 no longer the default.
5390 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5392 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5394 * lread.c (lisp_file_lexically_bound_p):

5402 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5404 * nsterm.m (constrainFrameRect): Always constrain when there is only
5405 one screen (Bug#10962).
5407 2012-04-13 Ken Brown <kbrown@cornell.edu>

5415 2012-04-11 Daniel Colascione <dancol@dancol.org>
5417 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5418 against is gone. It's better to use vfork now so that when Cygwin
5419 gains a new, working vfork, we use it automatically (bug#10398).
5421 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5423 * window.c (save_window_save): Obey window-point-insertion-type.

5439 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5441 * w32.c (w32_delayed_load): Record the full path of the library
5442 being loaded (bug#10424).
5444 2012-04-09 Glenn Morris <rgm@gnu.org>
5446 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5447 not just in the obarray, before snarfing them. (Bug#11036)
5449 * Makefile.in ($(leimdir)/leim-list.el):
5450 Pass EMACS rather than BUILT_EMACS.

5459 Add convenience `GNUTLS_LOG2i' macro.
5461 * gnutls.c (gnutls_log_function2i): Convenience log function.
5462 (emacs_gnutls_read): Use new log functions,
5463 `gnutls_handshakes_tried' process member, and

5474 * minibuf.c (Fread_variable): Callers changed.
5476 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5478 * xdisp.c (set_cursor_from_row): If the display string appears in
5479 the buffer at position that is closer to point than the position
5480 after the display string, display the cursor on the first glyph of
5481 the display string. Fixes cursor display when a 'display' text
5482 property immediately follows invisible text. (Bug#11094)
5484 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5486 composite.c: use 'double' consistently
5487 * composite.c (get_composition_id): Use 'double' consistently
5488 instead of converting 'float' to 'double' and vice versa; this is
5489 easier to understand and avoids a GCC warning.
5491 2012-04-09 Glenn Morris <rgm@gnu.org>
5493 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5494 preparation for dumping it with emacs. (Bug#4789)

5516 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5517 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5518 objects, as mark_maybe_pointer will catch them otherwise.
5519 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5520 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5522 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5524 Fix typo that broke non-Windows builds.
5525 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5533 ($(BLD)/xml.$(O)): New dependency list.
5535 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5536 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5537 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5538 [!WINDOWSNT]: New macros.
5539 (init_libxml2_functions, libxml2_loaded_p): New functions.
5540 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5541 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5542 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5543 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5545 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5546 Call init_libxml2_functions before calling libxml2 functions.
5547 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5549 * emacs.c: Don't include libxml/parser.h.
5550 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5551 xmlCleanupParser directly.
5553 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5555 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5557 * indent.c (Fvertical_motion): If there is a display string at
5558 point, use it.vpos to compute how many lines to backtrack after
5559 move_it_to point. (Bug#11133)

5563 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5564 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5565 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5566 macros related to unification of CJK characters. For the details,
5567 see the discussion following the message here:
5568 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5570 2012-04-04 Chong Yidong <cyd@gnu.org>
5572 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5574 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5576 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5577 instead of alloca. (Bug#11138)

5584 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5586 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5587 position we get to after a call to move_it_to fails the
5588 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5589 only if we wind up in a string from display property. (Bug#11063)
5591 * window.c (Fdelete_other_windows_internal): Invalidate the row
5592 and column information about mouse highlight, so that redisplay
5593 restores it after reallocating the glyph matrices. (Bug#7464)
5595 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5596 string comes from a `display' text property, use the buffer
5597 position of that property as if we actually saw that position in
5599 (move_it_by_lines): Remove the assertion that
5600 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5601 violated when there's a before-string at the beginning of a line.
5604 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5606 * xdisp.c (append_space_for_newline): If the default face was
5607 remapped, use the remapped face for the appended newline.
5608 (extend_face_to_end_of_line): Use the remapped default face for
5609 extending the face to the end of the line.
5610 (display_line): Call extend_face_to_end_of_line when the default
5611 face was remapped. (Bug#11068)
5613 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5615 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

5639 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5641 2012-03-25 Kenichi Handa <handa@m17n.org>
5643 * dispextern.h (struct glyph): Change the bit length of
5644 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5646 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5648 * s/ms-w32.h (tzname): Include time.h before redirecting to
5649 _tzname. Fixes the MSVC build. (Bug#9960)
5651 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5653 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5656 * xterm.c (XTread_socket): Only modify handling_signal if
5657 !SYNC_INPUT. (Bug#11080)
5659 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5661 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5662 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5663 when fetching a multibyte character consumes more bytes than
5664 CHAR_BYTES returns, due to unification of CJK characters in
5665 string_char. (Bug#11073)
5667 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5669 * process.c (wait_reading_process_output): Handle pty disconnect

5681 2012-03-21 Chong Yidong <cyd@gnu.org>
5683 * xfaces.c (Vface_remapping_alist): Doc fix.
5685 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5687 * w32proc.c (Fw32_set_console_codepage)
5688 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5699 it fit in a valid range (Bug#11003).
5701 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5703 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5704 that is not from display property, accept the row as a "cursor
5705 row" if one of the string's character has a non-nil `cursor'
5706 property. Fixes cursor positioning when there are newlines in
5707 overlay strings, e.g. in icomplete.el. (Bug#11035)
5709 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5711 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

5715 * eval.c (inhibit_lisp_code): Rename from
5716 inhibit_window_configuration_change_hook; move from window.c.
5718 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5719 * window.c (run_window_configuration_change_hook)
5720 (syms_of_window): Callers changed.
5722 2012-03-11 Chong Yidong <cyd@gnu.org>
5724 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5726 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5728 2012-03-10 Chong Yidong <cyd@gnu.org>
5730 * frame.c (other_visible_frames): Don't assume the selected frame
5731 is visible (Bug#10955).
5733 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5735 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5737 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5739 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5740 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5743 2012-03-03 Glenn Morris <rgm@gnu.org>
5745 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5747 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5749 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5750 position past the first glyph_row that ends at ZV. (Bug#10902)
5751 (redisplay_window, next_element_from_string): Fix typos in
5753 (redisplay_window): Pass to move_it_vertically the margin in
5754 pixels, not in screen lines.
5756 2012-03-02 Glenn Morris <rgm@gnu.org>
5758 * buffer.c (buffer-list-update-hook): Doc fix.
5760 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5762 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5763 push_it before setting up the iterator for the first overlay
5764 string, even if we have an empty string loaded.
5765 (next_overlay_string): If there's an empty string on the iterator
5766 stack, pop the stack. (Bug#10903)
5768 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5770 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5771 Suggested by Stefan Monnier in
5772 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5773 * alloc.c (widen_to_Lisp_Object): New static function.
5774 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5775 and widening them to Lisp_Objects. This would work even if
5776 USE_LSB_TAG is defined and wide integers are used, which might
5777 happen in a future version of Emacs.
5779 2012-02-25 Chong Yidong <cyd@gnu.org>
5781 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5784 * xselect.c (Fx_selection_exists_p): Doc fix.
5785 (x_clipboard_manager_save_all): Print an informative message
5786 before saving to clipboard manager.
5788 2012-02-24 Chong Yidong <cyd@gnu.org>

5818 when computing $valmask.
5820 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5821 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5822 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5823 It's useless in that case, and it can cause problems on hosts
5824 that allocate halves of EMACS_INT values separately.
5825 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5826 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5827 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5828 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5829 it avoids undefined behavior on hosts where shifting right by more
5830 than the word width has undefined behavior.
5832 2012-02-19 Chong Yidong <cyd@gnu.org>
5834 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

5878 highlight (Bug#9904).
5880 2012-02-12 Glenn Morris <rgm@gnu.org>

5912 * buffer.c (Fbuffer_local_variables)
5913 (buffer_lisp_local_variables): Handle unbound vars correctly;

5916 2012-02-07 Glenn Morris <rgm@gnu.org>
5918 * image.c (Fimagemagick_types): Doc fix.
5920 * image.c (imagemagick-render-type): Change it from a lisp object

5956 * character.c (char_width): Return EMACS_INT, not int.
5957 (char_width, c_string_width): Check for overflow when
5958 computing the width; this is possible now that individual
5959 characters can have unbounded width. Problem introduced
5960 by merge from Emacs 23 on 2012-01-19.

6618 to 4 (xorl, subq, cmpq, setbe).
6619 * alloc.c (pure): Always extern now, since that's the
6620 VIRT_ADDR_VARIES behavior.
6621 (PURE_POINTER_P): Use a single comparison, not two, for
6622 consistency with the new puresize.h.

6632 behave as if the cursor position were at the window margin.
6634 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6635 and the cursor position is out of bounds, behave as if the cursor

6666 * dispnew.c (verify_row_hash): Call row_hash for computing the
6667 hash code of a row, instead of duplicating code from xdisp.c.
6669 * dispextern.h (row_hash): Add prototype.
6671 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6673 * frame.c (delete_frame): Don't delete the terminal when the last

6705 * image.c (imagemagick_load_image): Fix typo.
6707 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6709 * xdisp.c (display_line): Move the call to
6710 highlight_trailing_whitespace before the call to

6782 (window_box_right, window_box_right_offset): Undo previous change,
6783 by removing the "extern"s.
6784 * intervals.c (adjust_intervals_for_insertion)
6785 (adjust_intervals_for_deletion): Undo previous change,
6786 making these static again.

6811 of temacs in GUI mode.
6813 2011-11-07 Martin Rudalics <rudalics@gmx.at>
6815 * window.h: Declare delete_all_child_windows instead of

6828 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6829 This is also needed for porting to any host where GC_MARK_STACK is
6830 not GC_MAKE_GCPROS_NOOPS.
6831 (which_symbols): Use it.
6833 2011-11-07 Kenichi Handa <handa@m17n.org>

6846 * xmenu.c (cleanup_widget_value_tree): New function.
6847 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6850 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
6852 Fix some portability problems with 'inline'.
6853 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6854 (window_box_width, window_box_left, window_box_left_offset)
6855 (window_box_right, window_box_right_offset): Declare extern.
6856 Otherwise, these inline functions do not conform to C99 and
6857 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6858 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6859 * intervals.c (adjust_intervals_for_insertion)
6860 (adjust_intervals_for_deletion): Now extern, because otherwise the
6861 extern inline functions 'offset_intervals' couldn't refer to it.
6862 (static_offset_intervals): Remove.
6863 (offset_intervals): Rewrite using the old contents of
6864 static_offset_intervals. The old version didn't conform to C99
6865 because an extern inline function contained a reference to an
6866 identifier with static linkage.
6868 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6870 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6888 (Fwindow_vscroll): Doc fix.
6889 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6890 argument, since it makes no sense to pass a live window and for
6891 consistency with window-child.

6921 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6922 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6923 Move terminal->reference_count++ just before making the frame official

7035 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
7037 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7038 so that this new function doesn't get optimized away by a
7039 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7041 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
7043 * frame.h (MOUSE_HL_INFO): Remove excess parens.
7045 2011-10-29 Eli Zaretskii <eliz@gnu.org>

7063 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
7064 Not clear what it was for, and it causes various bugs. (Bug#9839)
7066 2011-10-28 Eli Zaretskii <eliz@gnu.org>
7068 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
7069 possible random value that matches one of those tested as
7070 condition to clear the mouse face.
7072 2011-10-28 Chong Yidong <cyd@gnu.org>
7074 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

7099 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7101 (w32font_open_internal, compute_metrics):
7102 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7103 instead of calling the "wide" APIs directly.
7105 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
7107 * w32.h (syms_of_w32font): Add prototype.
7109 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
7111 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
7112 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
7113 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

7118 * process.c (make_process): Set gnutls_state to NULL.
7120 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7121 non-NULL, regardless of GNUTLS_INITSTAGE.
7122 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7123 an error. Set process slots as soon as we allocate them.

7169 current character, check also for next_en_type being WEAK_EN.
7170 (bidi_resolve_weak): Don't enter the expensive loop if the current
7171 position is before next_en_pos. Record the bidi type of the first
7172 non-ET, non-BN character we find, in addition to its position.
7173 (bidi_level_of_next_char): Invalidate next_en_type when
7174 next_en_pos is over-stepped.
7176 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7178 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7179 * editfns.c: Rewrite current-time-zone so that it invokes
7180 the equivalent of (format-time-string "%Z") to get the time zone name.
7181 This fixes a bug when the time zone name contains characters that
7182 need converting from the system time locale to Emacs internal format.
7183 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7184 that patch fixed format-time-string to do the conversion, but
7185 I forgot to fix current-time-zone.
7186 (format_time_string): New function, containing most of
7187 what Fformat_time_string used to contain.
7188 (Fformat_time_string): Rewrite in terms of format_time_string.
7189 This doesn't change this function's behavior.
7190 (current-time-zone): Rewrite to use format_time_string.
7191 This fixes the bug reported by Michael Schierl in
7192 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7193 Jason Rumney's 2007-06-07 change worked around this bug, but
7195 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7197 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7199 * xdisp.c (start_display): If the character at POS is displayed
7200 via a display vector, reset IT->current.dpvec_index to zero.
7201 (try_window_reusing_current_matrix): If a line ends in a display
7202 vector or the next line starts in a display vector, continue
7203 redrawing the window even though the character position of
7204 start_row was reached.
7207 2011-10-18 Chong Yidong <cyd@gnu.org>
7209 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7210 with nobreak-char-display too.
7212 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7214 Fix part 3 of bug#9771.
7215 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7216 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7217 non-neutral characters if the current character is a paragraph
7218 separator (a.k.a. Newline). This avoids running the same
7219 expensive loop twice, once when we consume the preceding newline
7220 and the other time when the line actually needs to be displayed.
7221 Avoid the loop when we see neutrals on the base embedding level
7222 following a character whose directionality is the same as the
7223 paragraph's. This avoids running the expensive loop when a line
7224 ends in a long sequence of neutrals, like control characters.
7225 Add assertion against STRONG_AL type. Slightly rearrange code
7226 that determines the type of a neutral given the first non-neutral
7228 (bidi_level_of_next_char): Set next_en_pos to zero when
7229 invalidating its info.
7231 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7233 * xdisp.c (push_display_prop): Determine whether to record string
7234 or buffer position by IT->string, not by IT->method. Allow
7235 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7236 (move_it_vertically_backward): Don't look for character position
7237 immediately after the newline when in a continuation line.
7240 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7242 * window.c (coordinates_in_window): Rewrite and delabelize
7243 vertical border check. (Bug#5357) (Bug#9618)
7245 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7247 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7248 errors in XSetWindowBorder (bug#9310).
7250 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7252 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7253 avoid crash when xmalloc overrun checking is enabled.
7255 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7257 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7258 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7259 cursor motion with <left> and <right> arrow keys.
7261 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7262 some callers set that themselves.
7264 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7266 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7267 display string and the previous row comes from the same string and
7268 is empty. (Bug#9739) (Bug#9738)
7270 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7272 * doc.c (get_doc_string): Encode file name (bug#9735).
7274 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7276 * bidi.c (bidi_level_of_next_char):
7277 * xdisp.c (get_visually_first_element): Remove old incorrect
7278 comments regarding the Unicode Line Separator character.
7280 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7282 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7284 * alloc.c (Fgc_status): Do not access beyond zombies array
7285 boundary if nzombies > MAX_ZOMBIES.
7286 * alloc.c (dump_zombies): Add missing format specifier.
7288 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7290 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7291 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7293 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7294 Some packages use them to denote characters with modifiers.
7296 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7298 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7299 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7300 matching a pp-number. Rename parameter var to var1.
7302 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7304 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7306 2011-10-08 Glenn Morris <rgm@gnu.org>
7308 * callint.c (Fcall_interactively): Give a more explicit error for the
7309 'c' case with a non-character input. (Bug#8479)
7311 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7313 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7315 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7316 lines that are hscrolled on the left.
7318 * dispnew.c (buffer_posn_from_coords): Account for a possible
7319 presence of header-line. (Bug#4426)
7321 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7323 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7324 Don't advertise functionality which we discourage or doesn't work.
7326 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7328 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7329 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7330 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7331 this makes Emacs dump core during garbage collection on rare
7332 occasions. sizeof is obviously inferior to offsetof here, so
7333 stick with offsetof.
7334 (GC_POINTER_ALIGNMENT): New macro.
7335 (mark_memory): Omit 3rd (offset) arg; caller changed.
7336 Don't assume EMACS_INT alignment is the same as pointer alignment.
7338 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7340 * keyboard.c (read_key_sequence_remapped): New var.
7341 (read_key_sequence): Compute remapping in the right buffer.
7342 (command_loop_1): Use read_key_sequence's remapping directly.
7344 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7346 * dired.c (file_name_completion): Don't expand file name.
7347 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7348 before checking file name handler.
7350 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7351 they've been requested explicitly (bug#9591).
7353 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7355 * keymap.c (Fsingle_key_description): Use make_specified_string
7356 instead of build_string to build string from push_key_description.
7359 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7361 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7362 This fixes a Y2038 bug on 64-bit hosts.
7363 * buffer.c (reset_buffer):
7364 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7365 (Fclear_buffer_auto_save_failure):
7366 Use 0, not -1, to represent an unset failure time, since time_t
7367 might not be signed.
7369 Remove dependency on glibc malloc internals.
7370 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7371 Move back here from lisp.h, but with their new implementations.
7372 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7373 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7374 * charset.c (charset_table_init): New static var.
7375 (syms_of_charset): Use it instead of xmalloc. This removes a
7376 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7377 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7378 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7379 Move back to alloc.c.
7380 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7381 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7383 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7385 * nsterm.m (windowDidResize): Call x_set_window_size only when
7386 ns_in_resize is true. Otherwise set pixelwidth/height and
7387 call change_frame_size (Bug#9628).
7389 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7391 Port --enable-checking=all to Fedora 14 x86-64.
7392 * charset.c (syms_of_charset): Also account for glibc malloc's
7393 internal overhead when calculating the initial malloc maximum.
7395 Port --enable-checking=all to Fedora 14 x86.
7396 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7398 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7399 (overrun_check_realloc, overrun_check_free):
7400 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7401 That way, xmalloc returns a properly-aligned pointer even if
7402 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7403 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7404 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7405 into account when calculating the initial malloc maximum.
7406 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7407 Move here from alloc.c, so that charset.c can use it too.
7408 Properly align; the old code wasn't right for common 32-bit hosts
7409 when configured with --enable-checking=all.
7410 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7411 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7413 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7415 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7418 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7420 * xdisp.c (compute_display_string_end): If there's no display
7421 string at CHARPOS, return -1.
7423 * bidi.c (bidi_fetch_char): When compute_display_string_end
7424 returns a negative value, treat the character as a normal
7425 character not covered by a display string. (Bug#9624)
7427 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7429 * lread.c (Fread_from_string): Fix typo in docstring.
7431 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7433 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7434 newline, reseat the iterator instead of bidi-iterating there one
7435 character at a time. (Bug#9610)
7436 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7437 TO_CHARPOS if the bidi iterator is at base embedding level.
7439 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7441 * lread.c (readevalloop): Use correct code for NBSP.
7442 (read1): Likewise. (Bug#9608)
7444 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7446 * dbusbind.c (Fdbus_register_signal): When service is not
7447 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7449 2011-09-25 Glenn Morris <rgm@gnu.org>
7451 * buffer.c (truncate-lines): Doc fix.
7453 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7455 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7456 (Fset_window_next_buffers): Doc fix.
7458 2011-09-24 Glenn Morris <rgm@gnu.org>
7460 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7462 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7464 Fix minor problems found by static checking.
7465 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7466 * indent.c (Fvertical_motion): Fix == vs = typo.
7468 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7470 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7471 Default value is now t. Doc fix.
7473 * indent.c (Fvertical_motion): Compute and apply the overshoot
7474 logic when moving up, not only when moving down. Fix the
7475 confusing name and values of the it_overshoot_expected variable;
7476 logic changes accordingly. (Bug#9254) (Bug#9549)
7478 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7479 CHARPOS is covered by a display string which includes newlines.
7480 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7481 is covered by a display string with embedded newlines.
7483 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7485 * dbusbind.c (Fdbus_register_signal): Add match rule to
7486 Vdbus_registered_objects_table. (Bug#9581)
7487 (Fdbus_register_method, Vdbus_registered_objects_table):
7490 2011-09-24 Jim Meyering <meyering@redhat.com>
7492 do not ignore write error for any output size
7493 The previous change was incomplete.
7494 While it makes emacs --batch detect the vast majority of stdout
7495 write failures, errors were still ignored whenever the output size is
7496 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7497 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7498 && echo FAIL: ignored write error
7499 FAIL: ignored write error
7500 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7501 && echo FAIL: ignored write error
7502 FAIL: ignored write error
7503 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7505 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

7508 non-successfully if a write error occurred on stdout. (Bug#9574)
7510 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7512 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7515 * dispextern.h (struct it): Update the comment documenting what
7518 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7520 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7521 a display string, extend search for cursor position to end of row.
7522 (find_row_edges): If the row ends in a newline from a display
7523 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7524 Handle the case of a display string with multiple newlines.
7525 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7526 non-empty line. Fixes confusing cursor motion with arrow keys at
7527 the beginning of a line that starts with whitespace.
7529 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7531 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7534 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7536 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7539 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7541 * xdisp.c (display_line): Record maximum and minimum buffer
7542 positions even if no glyphs were produced (e.g., by a zero-width
7543 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7544 buffer positions that will be removed from the glyph row because
7546 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7547 column is beyond frame width: don't subtract 1 "pixel" when
7548 computing width of the stretch.
7549 (reseat_at_next_visible_line_start): Undo the change made on
7550 2011-09-17 that saved paragraph information and restored it after
7551 the call to `reseat'. (Bug#9545)
7553 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7555 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7556 and turn window cursor on if cleared (Bug#9415).
7558 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7560 * search.c (boyer_moore): Take unibyte characters from pattern

7567 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7569 Fix minor problem found by static checking.
7570 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7571 initialized, to pacify gcc -Wuninitialized.
7573 * fileio.c: Report proper errno when syscall falls.
7574 (Finsert_file_contents): Save and restore errno,
7575 so that report_file_error outputs the correct diagnostic.
7576 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7578 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7580 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7582 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7584 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7585 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7587 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7589 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7590 about the current paragraph and restore it after the call to reseat.
7592 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7593 (bidi_find_paragraph_start): Search back for paragraph beginning
7594 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7595 (bidi_move_to_visually_next): Only trigger paragraph-related
7596 computations when the last character is a newline or at EOB, not
7597 just any NEUTRAL_B. (Bug#9470)
7599 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7600 truncated lines if point is covered by a display string. (Bug#9524)
7602 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7604 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7605 (cons_to_x_long): New function.
7606 (lisp_data_to_selection_data): Use it. Correct the test for
7607 short-versus-long data; it was negated. Break out of vector
7608 loop, for efficiency, when a long datum is discovered.
7610 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7612 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7614 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7616 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7617 GCC PR/17406) by declaring this function with external scope.
7619 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

7640 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7641 This occurs when processing a multibyte format.
7642 Problem reported by Wolfgang Jenker.
7644 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7646 * xdisp.c (try_cursor_movement): Only check for exact match if
7647 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7649 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7651 Remove unused external symbols.
7652 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7653 * xdisp.c (calc_pixel_width_or_height): Now static.
7654 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7655 * indent.c (check_display_width):
7656 * w32term.c: Fix comment to match code.
7657 * xterm.c, xterm.h (x_catching_errors): Remove.
7659 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7661 * xselect.c: Use signed conversions more consistently (Bug#9498).
7662 (selection_data_to_lisp_data): Assume incoming selection data are
7663 signed integers, not unsigned. This is to be consistent with
7664 outgoing selection data, which was modified to use signed integers
7665 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7666 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7667 expects long, not unsigned long.
7669 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7671 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7672 computation of loop end. Reported by Johan Bockgård
7675 2011-09-13 Chong Yidong <cyd@stupidchicken.com>

7679 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7681 * indent.c (compute_motion): Process display vector front to back
7682 rather than the other way around. (Bug#2496)
7684 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7686 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.

7694 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7695 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7697 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7699 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7700 value for non-existent files.
7702 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7704 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7705 set its "size" to -1. This will set the modtime_size field of
7706 the corresponding buffer to -1, which is what
7707 verify-visited-file-modtime expects for files that do not exist.
7710 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7712 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7714 * lisp.h: ... from here. push_key_description is no longer
7715 defined in keyboard.c, so its declaration should not be in
7716 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7717 logically belongs with push_key_description.
7719 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7721 * buffer.h: Include <sys/types.h> instead of <time.h>.
7722 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7723 Problem reported by Herbert J. Skuhra.
7725 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7727 * xml.c (parse_region): Make the parsing work for
7728 non-comment-starting XML files again (bug#9144).
7730 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7732 * image.c (gif_load): Fix calculation of bottom and right corner.
7735 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7737 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7738 redisplay in small windows.
7740 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7742 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7744 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7746 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7747 Operate on live windows only.
7749 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7751 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7753 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7755 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7756 only under bidi iteration.
7758 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7760 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7762 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7764 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7765 Without this fix, the command to link temacs failed due to an
7766 undefined symbol __builtin_isnan. This is because
7767 /usr/include/iso/math_c99.h #defines isnan(x) to
7768 __builtin_isnan(x), but the bundled gcc, which identifies itself
7769 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7771 * floatfns.c (isnan): #undef, and then #define to a clone of
7773 (Fisnan): Always define, since it's always available now.
7774 (syms_of_floatfns): Always define isnan at the Lisp level.
7776 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7778 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7780 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7782 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7783 The previous code assumed that file offsets (off_t values) fit in
7784 EMACS_INT variables, which is not true on typical 32-bit hosts.
7785 The code messed up by falsely reporting buffer overflow in cases
7786 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7787 when "big" contains more than 2**29 bytes, even though this
7788 inserts just one byte and does not overflow the buffer.
7789 (Finsert_file_contents): Store file offsets as off_t
7790 values, not as EMACS_INT values. Check for overflow when
7791 converting between EMACS_INT and off_t. When checking for
7792 buffer overflow or for overlap, take the offsets into account.
7793 Don't use EMACS_INT for small values where int suffices.
7794 When checking for overlap, fix a typo: ZV was used where
7795 ZV_BYTE was intended.
7796 (Fwrite_region): Don't assume off_t fits into 'long'.
7797 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7799 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7801 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7803 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7805 sprintf-related integer and memory overflow issues (Bug#9412).
7807 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7808 (esprintf, exprintf, evxprintf): New functions.
7809 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7810 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7811 (modify_event_symbol): Do not assume that the length of
7812 name_alist_or_stem is safe to alloca and fits in int.
7813 (Fexecute_extended_command): Likewise for function name and binding.
7814 (Frecursion_depth): Wrap around reliably on integer overflow.
7815 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7816 since some callers pass EMACS_INT values.
7817 (Fsingle_key_description): Don't crash if symbol name contains more
7818 than MAX_ALLOCA bytes.
7819 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7820 (get_minibuffer): Arg is now EMACS_INT, not int.
7821 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7822 (esprintf, exprintf, evxprintf): New decls.
7823 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7825 * dbusbind.c (signature_cat): New function.
7826 (xd_signature, Fdbus_register_signal):
7827 Do not overrun buffer; instead, report string overflow.
7829 * dispnew.c (add_window_display_history): Don't overrun buffer.
7830 Truncate instead; this is OK since it's just a log.
7832 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7833 even if the time zone offset is outlandishly large.
7834 Don't mishandle offset == INT_MIN.
7836 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7837 when creating daemon; the previous buffer-overflow check was incorrect.
7839 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7840 which has the guts of the old verror function.
7842 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7843 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7845 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7846 (font_unparse_xlfd): Don't blindly alloca long strings.
7847 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7848 fits in int, when using sprintf. Use single snprintf to count
7849 length of string rather than counting it via multiple sprintfs;
7850 that's simpler and more reliable.
7851 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7852 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7853 sprintf, in case result does not fit in int.
7855 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7856 (fontset_from_font): Print it.
7858 * frame.c (tty_frame_count): Now printmax_t, not int.
7859 (make_terminal_frame, set_term_frame_name): Print it.
7860 (x_report_frame_params): In X, window IDs are unsigned long,
7861 not signed long, so print them as unsigned.
7862 (validate_x_resource_name): Check for implausibly long names,
7863 and don't assume name length fits in 'int'.
7864 (x_get_resource_string): Don't blindly alloca invocation name;
7865 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7868 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7869 (xg_check_special_colors, xg_set_geometry):
7870 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7872 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7873 Use esprintf, not sprintf, in case result does not fit in int.
7875 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7876 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7877 it as a large positive number.
7878 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7879 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7881 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7882 in case result does not fit in int.
7884 * print.c (float_to_string): Detect width overflow more reliably.
7885 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7886 buffer overrun. Don't assume list length fits in 'int'. Treat
7887 print length of 0 as 0, not as infinity; to be consistent with other
7888 uses of print length in this function. Don't overflow print length
7889 index. Don't assume hash table size fits in 'long', or that
7890 vectorlike size fits in 'unsigned long'.
7892 * process.c (make_process): Use printmax_t, not int, to format
7893 process-name gensyms.
7895 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7897 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7898 to avoid potential buffer overrun.
7900 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7901 if X resource line is longer than 512 bytes.
7903 * xfns.c (x_window): Make sprintf buffer a bit bigger
7904 to avoid potential buffer overrun.
7906 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7908 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7910 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7912 Integer overflow fixes for scrolling, etc.
7913 Without these, Emacs silently mishandles large integers sometimes.
7914 For example, "C-u 4294967297 M-x recenter" was treated as if
7915 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7917 * xdisp.c (try_window_id): Check Emacs fixnum range before
7918 converting to 'int'.
7920 * window.c (window_scroll_line_based, Frecenter):
7921 Check that an Emacs fixnum is in range before assigning it to 'int'.
7922 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7923 values converted from Emacs fixnums.
7924 (Frecenter): Don't wrap around a line count if it is out of 'int'
7925 range; instead, treat it as an extreme value.
7926 (Fset_window_configuration, compare_window_configurations):
7927 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7929 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7930 that can exceed INT_MAX. Check that EMACS_INT value is in range
7931 before assigning it to the (possibly-narrower) index.
7932 (match_limit): Don't assume that a fixnum can fit in 'int'.
7934 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7937 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7938 (Fvertical_motion): Don't wrap around LINES values that don't fit
7939 in 'int'. Instead, treat them as extreme values. This is good
7940 enough for windows, which can't have more than INT_MAX lines anyway.
7942 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7944 * Require libxml/parser.h to avoid compilation warning.
7946 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7948 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7949 since this reportedly can destroy thread storage.
7951 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7953 * syntax.c (find_defun_start): Update all cache variables if
7954 exiting early (Bug#9401).
7956 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7958 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7960 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7961 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7962 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7964 * term.c (tty_append_glyph): New function.
7965 (produce_stretch_glyph): Static function and its prototype deleted.
7967 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7970 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7972 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7973 when checking :margin (Bug#9390).
7974 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7975 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7976 so that the name doesn't mislead. All uses changed.
7978 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7980 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7983 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7985 * xdisp.c (move_it_to): Don't bail out early when reaching
7986 position beyond to_charpos, if we are scanning backwards.
7987 (move_it_vertically_backward): When DY == 0, make sure we get to
7988 the first character in the line after the newline.
7990 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7992 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7993 (ccl_driver): Do not generate an out-of-range pointer.
7994 (Fccl_execute_on_string): Remove unnecessary check for
7995 integer overflow, noted by Stefan Monnier in
7996 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7997 Remove a FIXME that didn't need fixing.
7998 Simplify the newly-introduced buffer reallocation code.
8000 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8002 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8004 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8006 Integer and memory overflow issues (Bug#9196).
8008 * doc.c (get_doc_string): Rework so that
8009 get_doc_string_buffer_size is the actual buffer size, rather than
8010 being 1 less than the actual buffer size; this makes xpalloc more
8013 * image.c (x_allocate_bitmap_record, cache_image):
8014 * xselect.c (Fx_register_dnd_atom):
8015 Simplify previous changes by using xpalloc.
8017 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8018 since either will do and ptrdiff_t is convenient with xpalloc.
8020 * charset.c (charset_table_size)
8021 (struct charset_sort_data.priority): Now ptrdiff_t.
8022 (charset_compare): Don't overflow if priorities differ greatly.
8023 (Fsort_charsets): Don't assume list length fits in int.
8024 Check for size-calculation overflow when allocating sort data.
8025 (syms_of_charset): Allocate an initial charset table that is
8026 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8028 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8030 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8031 The actual value is always <= INT_MAX, and leaving it unsigned made
8032 overflow checking harder.
8034 * dispextern.h (struct glyph_matrix.rows_allocated)
8035 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8036 with xpalloc. The values are still always <= INT_MAX.
8038 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8040 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8041 (SAFE_NALLOCA): New macro.
8043 * region-cache.c (struct boundary.pos, find_cache_boundary)
8044 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8045 (set_cache_region, invalidate_region_cache)
8046 (revalidate_region_cache, know_region_cache, region_cache_forward)
8047 (region_cache_backward, pp_cache):
8048 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8049 so that ptrdiff_t * can be passed to xpalloc.
8050 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8051 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8052 (pp_cache): Don't assume cache_len fits in int.
8053 * region-cache.h: Adjust extern decls to match.
8055 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8056 EMACS_INT, since either will do, for xpalloc.
8058 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8059 (xnmalloc, xnrealloc, xpalloc): New functions.
8061 * bidi.c (bidi_shelve_header_size): New constant.
8062 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8063 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8065 * bidi.c (bidi_cache_shrink):
8066 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8068 Don't update size of array until after memory allocation succeeds,
8069 because xmalloc/xrealloc may not return.
8070 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8071 now that we have proper integer overflow checking.
8072 (record_overlay_string, overlay_strings): Catch overflows when
8073 calculating size of overlay_str_buf.
8075 * callproc.c (Fcall_process): Check for size overflow when
8076 calculating size of args2.
8077 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8078 Normally we prefer signed values, but sticking with ptrdiff_t would
8079 require adding more-complicated checks.
8081 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8082 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8083 Redo buffer-overflow calculations to avoid integer overflow.
8084 Add a FIXME comment where memory seems to be over-allocated.
8086 * character.c (Fstring): Check for size-calculation overflow.
8088 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8089 unnecessary integer overflow. Check for size overflow.
8090 (encode_coding_object): Don't update size until xmalloc succeeds.
8092 * composite.c (get_composition_id): Check for overflow in glyph
8093 length calculations.
8095 Integer and memory overflow fixes for display code.
8096 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8097 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8098 (scrolling_window): Check for overflow in size calculations.
8099 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8100 Don't assume glyph table len fits in int.
8101 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8102 (row_table_size): Now ptrdiff_t, not int.
8103 (scrolling_window): Avoid overflow in size calculations.
8104 Don't update size until allocation succeeds.
8105 * fns.c (concat): Check for overflow in size calculations.
8106 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8107 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8108 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8110 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8111 (get_doc_string): Check for size calculation overflow.
8112 Don't update size until allocation succeeds.
8113 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8114 EMACS_INT, where ptrdiff_t will do.
8115 (Fsubstitute_command_keys): Check for string overflow.
8117 * editfns.c (set_time_zone_rule): Don't assume environment length
8119 (message_length): Now ptrdiff_t, not int.
8120 (Fmessage_box): Don't update size until allocation succeeds.
8121 Don't assume message length fits in int.
8122 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8124 * emacs.c (main): Do not reallocate argv, since there is a null at
8125 the end that can be overwritten, and this way there's no need to
8126 worry about size-calculation overflow.
8127 (sort_args): Check for size-calculation overflow.
8129 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8131 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8133 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8134 (x_set_scroll_bar_width, x_figure_window_size):
8135 Check for integer overflow.
8136 (x_set_alpha): Do not assume XINT fits in int.
8138 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8139 This is for the members text_lines, text_cols, total_lines, total_cols,
8140 where the system imposes an 'int' limit.
8142 * fringe.c (Fdefine_fringe_bitmap):
8143 Don't update size until alloc works.
8145 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8146 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8148 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8149 Check for size-calculation overflow.
8150 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8151 do, as we prefer signed integers.
8152 (id_to_widget.max_size, id_to_widget.used)
8153 (xg_store_widget_in_map, xg_remove_widget_from_map)
8154 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8155 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8156 Use and return ptrdiff_t, not int.
8157 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8158 * gtkutil.h: Change prototypes to match the above.
8160 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8161 are duplicate now that they've been promoted to lisp.h.
8162 (x_allocate_bitmap_record, x_alloc_image_color)
8163 (make_image_cache, cache_image, xpm_load):
8164 Don't update size until alloc is done.
8165 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8167 Check for size calculation overflow.
8168 (ct_colors_allocated_max): New constant.
8169 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
8172 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
8173 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
8174 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8175 Use ptrdiff_t, not int, to count maps.
8176 (read_char_minibuf_menu_prompt): Check for overflow in size
8177 calculations. Don't update size until allocation succeeds.
8178 Redo calculations to avoid overflow.
8179 * keyboard.h: Change prototypes to match the above.
8181 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
8183 (current_minor_maps): Check for size calculation overflow.

8205 (Fset_match_data): Don't assume list lengths fit in 'int'.
8207 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8208 for command line length. Do not attempt to address one before the
8209 beginning of an array, as that's not portable.

8214 (encode_terminal_code, calculate_costs): Check for size
8215 calculation overflow.
8216 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
8217 table lengths and related sizes. Don't update size until alloc
8218 done. Redo calculations to avoid overflow.

8237 Use ptrdiff_t, not int, for sizes.
8238 (Finternal_make_lisp_face, cache_face):
8239 Check for size calculation overflow.
8240 (cache_face): Treat size calculation overflows as if they were
8241 memory exhaustion (the usual treatment), rather than aborting.
8243 * xfns.c (x_encode_text, x_set_name_internal)
8244 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8245 sizes, since they can exceed INT_MAX in size. Check for size
8246 calculation overflow.
8248 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8249 (xg_select): Check for size calculation overflow.
8250 Don't update size until alloc done.
8252 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8253 as sprintf is limited to int lengths.
8255 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8256 (X_LONG_MIN): New macros.
8257 Use them to make the following changes clearer.
8258 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8259 This change doesn't affect the value now, but it may help remind
8260 future maintainers not to raise the value too much later.
8261 (SELECTION_QUANTUM): Remove, replacing with ...
8262 (selection_quantum): ... new function, which avoids overflow.
8264 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8265 assumption that selection length fits in 'int'.
8266 (x_reply_selection_request, x_handle_selection_request)
8267 (x_get_window_property, receive_incremental_selection)

8278 (lisp_data_to_selection_data, x_property_data_to_lisp):
8279 Check for size-calculation overflow.

8282 Don't store size until memory allocation succeeds.
8283 (x_get_window_property): Plug memory leak on memory exhaustion.
8284 Don't double-block input; malloc is safe here. Don't assume 2**34
8285 - 4 fits in unsigned long. Add an xassert to check
8286 XGetWindowProperty overflow. Be more careful about overflow
8287 calculations, and distinguish size from memory overflow better.
8288 (receive_incremental_selection): When tracing, don't assume
8289 unsigned int is less than INT_MAX.
8290 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8291 harmful) conversions of unsigned short to int.
8292 (lisp_data_to_selection_data): Don't assume that integers
8293 in the range -65535 through -1 fit in an X unsigned short.
8294 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8295 result parameters unless successful. Rely on cons_to_unsigned
8296 to report problems with elements; the old code wasn't right anyway.
8297 (x_check_property_data): Check for int overflow; we cannot use
8298 a wider type due to X limits.
8299 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8331 * lisp.h (hash_lookup, hash_put):
8332 * minibuf.c (Ftest_completion):
8333 Use ptrdiff_t for hash table indexes, not int (which is too
8334 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8335 32-bit --with-wide-int hosts).
8337 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8338 Add a FIXME comment about memory leaks.

8367 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8368 (x_send_scroll_bar_event): Likewise. Check that the size does not
8369 exceed limits imposed by XClientMessageEvent, as well as the usual
8370 ptrdiff_t and size_t limits.
8372 * keyboard.c: Overflow, signedness and related fixes.
8373 (make_lispy_movement): Use same integer type in forward decl
8374 that is used in the definition.
8375 (read_key_sequence, keyremap_step):
8376 Change bufsize argument back to int, undoing my 2011-03-30 change.
8377 We prefer signed types, and int is wide enough here.
8378 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8379 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8380 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8381 length, not size_t. Use ptrdiff_t for index, not int.
8382 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8383 possibility of integer overflow.

8406 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8407 (lookup_image): Remove unnecessary tests.

8409 since parse_image_check makes sure they fit into int.
8410 (png_load, gif_load, svg_load_image):
8411 Prefer int to unsigned where either will do.
8412 (tiff_handler): New function, combining the cores of the
8413 old tiff_error_handler and tiff_warning_handler.
8414 This function is rewritten to use vsnprintf and thereby avoid
8415 stack buffer overflows. It uses only the features of vsnprintf
8416 that are common to both POSIX and native Microsoft.
8417 (tiff_error_handler, tiff_warning_handler): Use it.
8418 (tiff_load, gif_load, imagemagick_load_image):
8419 Don't assume :index value fits in 'int'.
8420 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8421 (imagemagick_load_image): Check that crop parameters fit into
8422 the integer types that MagickCropImage accepts. Don't assume
8423 Vimagemagick_render_type has a nonnegative value. Don't assume
8424 size_t fits in 'long'.
8425 (gs_load): Use printmax_t to print the widest integers possible.

8438 handle_single_display_spec, not just 1 or zero.
8439 (handle_single_display_spec): If the display spec is of the form
8440 `(space ...)', and specifies display in the text area, return 2
8442 (try_cursor_movement): Check for the need to scroll more
8443 accurately, and prefer exact match for point under bidi.
8444 Don't advance `row' beyond the last row of the window.
8446 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8447 into disp_prop; all users changed.
8449 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8462 buffers, return left-to-right.
8463 (set_cursor_from_row): Consider candidate row a win if its glyph

8465 positioning on the newline at EOL of R2L text within L2R
8466 paragraph, and vice versa.
8467 (try_cursor_movement): Check continued rows, in addition to
8468 continuation rows. Fixes unwarranted scroll when point enters a
8469 continued line of R2L text within an L2R paragraph, or vice versa.
8470 (cursor_row_p): Consider the case of point being equal to
8471 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8472 from the end of a short line to the beginning of a continued line
8473 of R2L text within L2R paragraph.
8474 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8500 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8501 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8502 candidate is selected by the mouse, and that candidate has a
8503 composed character under the mouse.
8505 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8506 coordinates reported by pos-visible-in-window-p for a composed

8521 * image.c (gif_load): Don't assume that each subimage has the same
8522 dimensions as the base image. Handle disposal method that is
8523 "undefined" by the gif spec (Bug#9335).
8525 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8527 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8532 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8533 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8534 from an Org mode buffer to a Speedbar frame.
8536 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8537 a composition, take its buffer position from IT->cmp_it.charpos.
8538 Fixes cursor positioning at the beginning of a line that begins
8539 with a composed character.
8541 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8543 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8544 character bidirectional type, use STRONG_L instead. Fixes crashes
8545 in a buffer produced by `describe-categories'.
8547 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8548 members before the level stack, so they would be saved and
8549 restored when copying iterator state. Fixes incorrect reordering
8550 around TABs covered by display properties.
8552 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8640 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8641 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit

8648 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8649 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8650 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8651 (QCgnutls_bootprop_verify_hostname_error)
8652 (QCgnutls_bootprop_callbacks_verify): Rename from
8653 Qgnutls_bootprop_..., all uses changed.
8655 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8658 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8660 * xfaces.c (Qframe_set_background_mode): Now static.
8661 * dispextern.h (Qframe_set_background_mode): Remove decl.
8663 * process.c (Fnetwork_interface_info): Declare local only if needed.
8665 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8667 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8668 (Fnetwork_interface_list): Allocate in increments of bytes instead
8669 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8670 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8672 (struct ifflag_def): notrailers is smart on OSX.
8673 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8674 Get hardware address with getifaddrs if available.
8676 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8678 * xdisp.c (iterate_out_of_display_property): xassert that
8679 IT->position is set to within IT->object's boundaries. Break from
8680 the loop as soon as EOB is reached; avoids infloops in redisplay
8681 when IT->position is set up wrongly due to some bug.
8682 Set IT->current to match the bidi iterator unconditionally.
8683 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8684 entry. Force push_it to save on the stack the current
8685 buffer/string position, to be restored by pop_it. Fix flags in
8686 the iterator structure wrt the object coming from a display
8687 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8688 properties. (Bug#9284)
8690 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8692 * fontset.c (fontset_get_font_group): Add proper type checks.
8695 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8697 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
8698 and LC_VERSION_MIN_MACOSX.
8699 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8700 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8702 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8704 * xdisp.c (forward_to_next_line_start): Allow to use the
8705 no-display-properties-and-no-overlays under bidi display.
8706 Set disp_pos in the bidi iterator to avoid searches for display
8707 properties and overlays.
8709 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8711 * editfns.c (Fset_time_zone_rule): Document relationship with the
8714 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8715 the font entity extracted from the cache (Bug#8109).
8717 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8719 * composite.c (autocmp_chars): Don't reset point. That is done by
8720 restore_point_unwind (Bug#5984).
8722 2011-08-07 Juri Linkov <juri@jurta.org>
8724 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8725 to show the arg `TIME' instead of `TIMEVAL'.
8727 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8729 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8730 display property strides EOL and includes a newline, as in
8731 longlines-mode. (Bug#9254)
8732 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8733 word-wrap under bidirectional display. (Bug#9224)
8735 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8736 is non-zero, even if the data buffer is NULL. Fixes a crash in
8737 vertical-motion with longlines-mode. (Bug#9254)
8739 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8741 * bidi.c <bidi_cache_total_alloc>: Now static.
8742 (bidi_initialize): Initialize bidi_cache_total_alloc.
8744 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8747 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8748 amount allocated this far in `bidi_cache_total_alloc'.
8749 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8750 non-zero, only free the data buffer without restoring the cache
8751 contents. All callers changed.
8753 * dispextern.h (bidi_unshelve_cache): Update prototype.
8755 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8756 (move_it_in_display_line, move_it_to)
8757 (move_it_vertically_backward, move_it_by_lines): Replace the call
8758 to xfree to an equivalent call to bidi_unshelve_cache.
8759 (move_it_in_display_line_to): Fix logic of returning
8760 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8762 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8764 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8765 came from a string character with a `cursor' property. (Bug#9229)
8767 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8769 * Makefile.in (LIB_PTHREAD): New variable.
8770 (LIBES): Add LIB_PTHREAD (Bug#9216).
8772 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8773 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8775 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8777 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8779 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8781 * xterm.c (x_find_topmost_parent): New function.
8782 (x_set_frame_alpha): Find topmost parent window with
8783 x_find_topmost_parent and set the property there also (bug#9181).
8784 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8786 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8788 * callproc.c (Fcall_process): Avoid vfork clobbering
8789 the local vars buffer, coding_systems, current_dir.
8791 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8793 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8795 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8797 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8798 so that it is not optimized away.
8800 * xdisp.c (compute_display_string_pos): Remove unused local.
8802 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8804 Fix slow cursor motion and scrolling in large buffers with
8805 selective display, like Org Mode buffers. (Bug#9218)
8807 * dispextern.h (struct bidi_it): New member disp_prop_p.
8809 * xdisp.c: Remove one-slot cache of display string positions.
8810 (compute_display_string_pos): Accept an additional argument
8811 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8812 for a display string or property. If found, set DISP_PROP_P
8815 * bidi.c (bidi_fetch_char): Accept an additional argument
8816 DISP_PROP_P, and pass it to compute_display_string_pos.
8817 Only handle text covered by a display string if DISP_PROP_P is returned
8818 non-zero. All callers of bidi_fetch_char changed.
8820 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8822 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8824 2010-12-03 Don March <don@ohspite.net>
8826 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8827 last character M-[char] is translated to ESC [char] (bug#7541).
8829 2011-08-02 Kenichi Handa <handa@m17n.org>
8831 * lisp.h (uniprop_table): Extern it.
8833 * chartab.c (uniprop_table): Make it non-static.
8835 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8837 * xdisp.c (forward_to_next_line_start): Accept additional argument
8838 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8840 (reseat_at_next_visible_line_start): Use the bidi iterator state
8841 returned by forward_to_next_line_start to restore the state of
8842 it->bidi_it after backing up to previous newline. (Bug#9212)
8844 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8846 * regex.c (re_comp): Protoize.
8847 (re_exec): Fix return type.
8848 (regexec): Fix type of `ret'. (Bug#9203)
8850 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8852 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8853 This is needed if max-image-size is a floating-point number.
8855 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8857 * print.c (print_object): Print empty symbol as ##.
8859 * lread.c (read1): Read ## as empty symbol.
8861 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8863 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8864 setting frame foreground color (Bug#9175).
8865 (x_set_background_color): Likewise.
8867 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8868 contents (Bug#9176).
8869 (EmacsTooltip -init): Remove bezels and add shadows to
8872 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8873 or scroll bar (Bug#8470).
8875 * nsfont.m (nsfont_open): Remove assignment to voffset and
8876 unnecessary vars hshink, expand, hd, full_height, min_height.
8877 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8879 * nsterm.h (nsfont_info): Remove voffset field.
8881 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8883 Implement strike-through and overline on NextStep (Bug#8863).
8885 * nsfont.m (nsfont_open): Use underline position provided by font,
8886 instead of hard-coded value of 2.
8887 (nsfont_draw): Call ns_draw_text_decoration instead.
8889 * nsterm.h: Add declaration for ns_draw_text_decoration.
8891 * nsterm.m (ns_draw_text_decoration): New function for drawing
8892 underline, overline, and strike-through.
8893 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8894 ns_draw_text_decoration. Change treatment of cursor drawing to
8895 accommodate underlining, etc.
8897 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8899 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8902 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8904 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8905 Without this fix, if a signal arrives just after memory fills up,
8906 'malloc' might be invoked reentrantly.
8908 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8909 In other words, assume that every image size is allowed, on non-X
8910 hosts. This assumption is probably wrong, but it lets Emacs compile.
8912 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8914 * regex.c (re_iswctype): Convert return values to boolean.
8916 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8918 * xdisp.c (compute_display_string_pos): Don't use cached display
8919 string position if the buffer had its restriction changed.
8922 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8924 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8926 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8928 Integer signedness and overflow and related fixes. (Bug#9079)
8930 * bidi.c: Integer size and overflow fixes.
8931 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8932 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8933 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8934 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8935 (bidi_find_other_level_edge):
8936 Use ptrdiff_t instead of EMACS_INT where either will do.
8937 This works better on 32-bit hosts configured --with-wide-int.
8938 (bidi_cache_ensure_space): Check for size-calculation overflow.
8939 Use % rather than repeated addition, for better worst-case speed.
8940 Don't set bidi_cache_size until after xrealloc returns, because it
8942 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8943 (bidi_cache_ensure_space): Also check that the bidi cache size
8944 does not exceed that of the largest Lisp string or buffer. See Eli
8945 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8947 * alloc.c (__malloc_size_t): Remove.
8948 All uses replaced by size_t. See Andreas Schwab's note
8949 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8951 * image.c: Improve checking for integer overflow.
8952 (check_image_size): Assume that f is nonnull, since
8953 it is always nonnull in practice. This is one less thing to
8954 worry about when checking for integer overflow later.
8955 (x_check_image_size): New function, which checks for integer
8956 overflow issues inside X.
8957 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8958 This removes the need for a memory_full check.
8959 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8960 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8961 (xbm_read_bitmap_data): Change locals back to 'int', since
8962 their values must fit in 'int'.
8963 (xpm_load_image, png_load, tiff_load):
8964 Invoke x_create_x_image_and_pixmap earlier,
8965 to avoid much needless work if the image is too large.
8966 (tiff_load): Treat overly large images as if
8967 x_create_x_image_and_pixmap failed, not as malloc failures.
8968 (gs_load): Use x_check_image_size.
8970 * gtkutil.c: Omit integer casts.
8971 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8972 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8974 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8976 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8977 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8978 would wrongly return t on a 64-bit host.
8980 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8981 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8982 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8983 and therefore cause GCC to emit a bogus diagnostic in some cases.
8985 * image.c: Integer signedness and overflow and related fixes.
8986 This is not an exhaustive set of fixes, but it's time to
8987 record what I've got.
8988 (lookup_pixel_color, check_image_size): Remove redundant decls.
8989 (check_image_size): Don't assume that arbitrary EMACS_INT values
8990 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8991 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8992 (tiff_load, imagemagick_load_image):
8993 Check for overflow in size calculations.
8994 (x_create_x_image_and_pixmap): Remove unnecessary test for
8995 xmalloc returning NULL; that can't happen.
8996 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8997 (xpm_color_bucket): Use better integer hashing function.
8998 (xpm_cache_color): Don't possibly over-allocate memory.
8999 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9000 (gif_memory_source):
9001 Use ptrdiff_t, not int or size_t, to record sizes.
9002 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9003 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9004 either works, as we prefer signed integers.
9005 (tiff_read_from_memory, tiff_write_from_memory):
9006 Return tsize_t, not size_t, since that's what the TIFF API wants.
9007 (tiff_read_from_memory): Don't fail simply because the read would
9008 go past EOF; instead, return a short read.
9009 (tiff_load): Omit no-longer-needed casts.
9010 (Fimagemagick_types): Don't assume size fits into 'int'.
9012 Improve hashing quality when configured --with-wide-int.
9013 * fns.c (hash_string): New function, taken from sxhash_string.
9014 Do not discard information about ASCII character case; this
9015 discarding is no longer needed.
9016 (sxhash-string): Use it. Change sig to match it. Caller changed.
9017 * lisp.h: Declare it.
9018 * lread.c (hash_string): Remove, since we now use fns.c's version.
9019 The fns.c version returns a wider integer if --with-wide-int is
9020 specified, so this should help the quality of the hashing a bit.
9022 * emacs.c: Integer overflow minor fix.
9023 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9024 Define only if GNU_LINUX.
9025 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9027 * dispnew.c: Integer signedness and overflow fixes.
9028 Remove unnecessary forward decls, that were a maintenance hassle.
9029 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9031 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9032 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9033 (prepare_desired_row, line_draw_cost):
9034 Use int, not unsigned, where either works.
9035 (save_current_matrix, restore_current_matrix):
9036 Use ptrdiff_t, not size_t, where either works.
9037 (init_display): Check for overflow more accurately, and without
9038 relying on undefined behavior.
9040 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9041 Remove, replacing with the new symbols in lisp.h. All uses changed.
9042 * fileio.c (make_temp_name):
9043 * filelock.c (lock_file_1, lock_file):
9044 * xdisp.c (message_dolog):
9045 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9046 Use pMd etc. instead.
9047 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9048 replacing the pWIDE etc. symbols removed from editfns.c.
9050 * keyboard.h (num_input_events): Now uintmax_t.
9051 This is (very slightly) less likely to mess up due to wraparound.
9054 * buffer.c: Integer signedness fixes.
9055 (alloc_buffer_text, enlarge_buffer_text):
9056 Use ptrdiff_t rather than size_t when either will do, as we prefer
9059 * alloc.c: Integer signedness and overflow fixes.
9060 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9061 (__malloc_size_t): Default to size_t, not to int.
9062 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9063 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9064 Prefer ptrdiff_t to size_t when either would do, as we prefer
9066 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9067 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9068 Now const. Initialize with values that are in range even if char
9070 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9071 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9072 These functions do the right thing with sizes > 2**32.
9073 (check_depth): Now ptrdiff_t, not int.
9074 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9075 Adjust to new way of storing sizes. Check for size overflow bugs
9077 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9078 slightly wrong anyway, as it missed one instance of
9079 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9080 (refill_memory_reserve): Omit needless cast to size_t.
9081 (mark_object_loop_halt): Mark as externally visible.
9083 * xselect.c: Integer signedness and overflow fixes.
9084 (Fx_register_dnd_atom, x_handle_dnd_message):
9085 Use ptrdiff_t, not size_t, since we prefer signed.
9086 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9087 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9088 x_dnd_atoms_size and x_dnd_atoms_length.
9090 * doprnt.c: Prefer signed to unsigned when either works.
9092 * doprnt.c (doprnt):
9094 * xdisp.c (vmessage):
9095 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9096 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9097 prefer signed arithmetic to avoid comparison confusion.
9098 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9099 but is a bit tricky.
9101 Assume freestanding C89 headers, string.h, stdlib.h.
9102 * data.c, doprnt.c, floatfns.c, print.c:
9103 Include float.h unconditionally.
9104 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9105 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9106 * regex.c: Likewise for stddef.h, string.h.
9107 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9108 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9109 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9110 (STDC_HEADERS): Remove obsolete defines.
9111 * sysdep.c: Include limits.h unconditionally.
9113 Assume support for memcmp, memcpy, memmove, memset.
9114 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9115 * regex.c (memcmp, memcpy):
9116 Remove; we assume C89 now.
9118 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9119 (__malloc_safe_bcopy): Remove; no longer needed.
9121 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9122 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9123 well either way, and we prefer signed to unsigned.
9125 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9127 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9128 closes the connection while we're reading (bug#9182).
9130 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9132 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9133 are specified (Bug#9168).
9135 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9137 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9138 Found by GCC static checking and --with-wide-int on a 32-bit host.
9140 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9142 * xdisp.c (compute_display_string_pos): Fix logic of caching
9143 previous display string position. Initialize cached_prev_pos to
9144 -1. Fixes slow-down at the beginning of a buffer.
9146 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9148 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9149 for attrs[LFACE_FONTSET_INDEX].
9151 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9153 * xml.c (parse_region): Remove unused local
9154 that was recently introduced.
9156 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9158 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9159 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9161 * xdisp.c (move_it_in_display_line_to): Record the best matching
9162 position for TO_CHARPOS while scanning the line, and restore it on
9163 exit if none of the characters scanned was an exact match.
9164 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9165 when exact match is impossible due to invisible text, and the
9166 lines are truncated.
9168 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9170 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9173 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9175 Fix a significant slow-down of cursor motion with C-n, C-p,
9176 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9177 auto-repeat under bidi redisplay in fontified buffers.
9178 * xdisp.c (compute_stop_pos_backwards): New function.
9179 (next_element_from_buffer): Call compute_stop_pos_backwards to
9180 find a suitable prev_stop when we find ourselves before
9182 (reseat): Don't look for prev_stop, as that could mean a very long
9184 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9185 <cached_disp_overlay_modiff>: Cache for last found display string
9187 (compute_display_string_pos): Return the cached position if asked
9188 about the same buffer in the same area of character positions, and
9189 the buffer wasn't changed since the time the display string
9190 position was cached.
9192 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9194 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9195 is an integer, which is important for empty lines. (Bug#9149)
9197 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9199 * frame.c (Fmodify_frame_parameters): In tty case, update the
9200 default face if necessary (Bug#4238).
9202 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9204 * editfns.c (Fstring_to_char): No need to explain what a character
9205 is in the docstring (Bug#6576).
9207 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9209 * xml.c (parse_region): Make sure we always return a tree.
9211 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9213 * xml.c (parse_region): If a document contains only comments,
9216 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9218 * xml.c (make_dom): Return comments, too.
9220 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9223 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9224 and the surrounding thread.
9225 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9226 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9227 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9229 * s/openbsd.h (BROKEN_SIGIO): Define.
9230 * unexelf.c (unexec) [__OpenBSD__]:
9231 Don't update the .mdebug section of the Alpha COFF symbol table.
9233 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9235 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9238 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9240 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9241 This fixes some race conditions on the permissions of any newly
9244 * alloc.c (valid_pointer_p): Use pipe, not open.
9245 This fixes some permissions issues when debugging.
9247 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9248 If fchown fails to set both uid and gid, try to set just gid,
9249 as that is sometimes allowed. Adjust the file's mode to eliminate
9250 setuid or setgid bits that are inappropriate if fchown fails.
9252 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9254 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9255 to compare Lisp_Objects.

9266 symbol character follows.
9268 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9270 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9271 This works around a problem with the previous change to Fcopy_file.
9272 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9273 and without this change, GCC might complain about discarding
9274 fchown's return value.
9276 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9278 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9280 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9282 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9284 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9286 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9287 it's used from the C level.
9289 * process.c: Use the same condition for POLL_FOR_INPUT in both
9290 keyboard.c and process.c (bug#1858).
9292 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9299 * doc.c (Fsubstitute_command_keys): Revert last change.
9301 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9303 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9304 quotes the next character, and doesn't affect other longer
9305 sequences (bug#8935).
9307 * lread.c (syms_of_lread): Clarify that is isn't only
9308 `eval-buffer' and `eval-defun' that's affected by
9309 `lexical-binding' (bug#8460).
9311 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9313 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9314 bidi redisplay when a line includes both an image and is truncated.
9316 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9318 Fix minor problems found by static checking.
9319 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9320 (elsz): Now a signed constant, not a size_t var. We prefer signed
9321 types to unsigned, to avoid integer comparison confusion. Without
9322 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9323 "cannot optimize loop, the loop counter may overflow", a symptom
9325 * indent.c (Fvertical_motion): Mark locals as initialized.
9326 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9328 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9330 * search.c (Fre_search_backward): Mention `case-fold-search' in
9331 all the re_search_* functions (bug#8138).

9349 Initialize itb.string.lstring.
9350 (init_iterator): Call bidi_init_it only of a valid
9351 buffer position was specified. Initialize paragraph_embedding to
9353 (reseat_to_string): Initialize the bidi iterator.
9354 (display_string): If we need to ignore text properties of
9355 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

9358 `text_pos *'; all callers changed. Support display properties on
9360 (compute_display_string_end): Support display properties on Lisp
9362 (init_iterator, reseat_1, reseat_to_string): Initialize the
9363 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9364 when iterating on a string not from display properties).
9365 (compute_display_string_pos, compute_display_string_end):
9366 Fix calculation of the object to scan. Fixes an error when using
9368 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9369 base_level_stop; instead, set base_level_stop to BEGV.
9370 Fixes crashes in vertical-motion.
9371 (next_element_from_buffer): Improve commentary for when
9372 the iterator is before prev_stop.
9373 (init_iterator): Initialize bidi_p from the default value of
9374 bidi-display-reordering, not from buffer-local value. Use the
9375 buffer-local value only if initializing for buffer iteration.
9376 (handle_invisible_prop): Support invisible properties on strings
9377 that are being bidi-reordered.
9378 (set_iterator_to_next): Support bidi reordering of C strings and

9388 (next_element_from_string, next_element_from_c_string)
9389 (next_element_from_buffer): Add xassert's for correspondence
9390 between IT's object being iterated and it->bidi_it.string

9395 (get_visually_first_element): New function, refactored from common
9396 parts of next_element_from_buffer, next_element_from_string, and
9397 next_element_from_c_string.
9398 (tool_bar_lines_needed, redisplay_tool_bar)
9399 (display_menu_bar): Force left-to-right direction. Add a FIXME
9400 comment for making that be controlled by a user option.

9410 iterator for displaying display or overlay strings.
9411 (forward_to_next_line_start): Don't use the shortcut if
9413 (back_to_previous_visible_line_start): If handle_display_prop
9414 pushed the iterator stack, restore the internal state of the bidi
9415 iterator by calling bidi_pop_it same number of times.
9416 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9417 and we are bidi-iterating, don't decrement the iterator position;
9418 instead, set the first_elt flag in the bidi iterator, to produce
9420 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9421 (push_display_prop): xassert that we are iterating a buffer.
9422 (push_it, pop_it): Save and restore paragraph_embedding member.
9423 (handle_single_display_spec, next_overlay_string)

9426 correctly. Don't assume unibyte strings are not bidi-reordered.
9427 (compute_display_string_pos)
9428 (compute_display_string_end): Fix handling the case of C string.
9429 (push_it, pop_it): Save and restore from_disp_prop_p.
9430 (handle_single_display_spec, push_display_prop): Set the
9431 from_disp_prop_p flag.
9432 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9438 (handle_single_display_spec, get_overlay_strings_1)
9439 (push_display_prop): Fix initialization of paragraph direction for
9440 string when that of the parent object is not yet determined.

9454 (back_to_previous_visible_line_start, reseat_1)
9455 (init_iterator): Empty the bidi cache "stack".
9456 (move_it_in_display_line_to): If iterator ended up at

9479 (bidi_move_to_visually_next): Compare cache index with
9480 bidi_cache_start rather than with zero.
9481 (bidi_fetch_char): Accept new argument STRING; all callers
9482 changed. Support iteration over a string. Support strings with
9483 display properties. Support unibyte strings. Fix the type of
9484 `len' according to what STRING_CHAR_AND_LENGTH expects.
9485 (bidi_paragraph_init, bidi_resolve_explicit_1)

9891 Random fixes. E.g., (random) never returned negative values.
9892 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9893 subseconds part to the entropy, as that's a bit more random.
9894 Prefer signed to unsigned, since the signedness doesn't matter and
9895 in general we prefer signed. When given a limit, use a
9896 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9897 latter isn't right if USE_2_TAGS_FOR_INTS.
9898 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9899 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9912 This is more efficient than Ffile_directory_p and avoids a minor race.
9914 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9916 * buffer.c (Foverlay_put): Say what the return value is
9919 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9920 is a directory before asking whether to use the file name

9923 error be more correct.
9925 * fns.c (Frequire): Remove the mention of the .gz files, since
9926 that's installation-specific, but keep the mention of

9942 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

10027 (something_changedCB): New function for HAVE_GSETTINGS.
10028 (something_changedCB): HAVE_GCONF: Call store_monospaced_changed
10029 with value as argument.
10030 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
10031 g_settings_new (Bug#8967). Do not create gsettings_obj.

10042 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
10044 * eval.c (struct backtrace): Simplify and port the data structure.
10045 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10046 signed bit field, as this assumption is not portable and it makes
10047 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10048 "char debug_on_exit : 1" as this is not portable either; instead,
10049 use the portable "unsigned int debug_on_exit : 1". Remove unused
10050 member evalargs. Remove obsolete comments about cc bombing out.
10052 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
10054 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

10087 clearly which files are directly included by each source file,
10088 and not through other includes.
10090 2011-06-27 Martin Rudalics <rudalics@gmx.at>

10095 the overlay's window property doesn't match the current window.
10097 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
10098 (Fwindow_hchild): Rename to Fwindow_left_child.

10120 (emacs_fixed_new): Set priv->f to argument.
10121 (emacs_fixed_get_preferred_width)
10122 (emacs_fixed_get_preferred_height): Use min_width/height from
10123 frames size_hint to set minimum and natural (Bug#8919).
10124 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10125 and use min_width/height from frames size_hint to set
10126 min_width/height (Bug#8919).

10146 Use gnulib's dup2 module instead of rolling our own.
10147 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
10149 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10151 * dispnew.c (scrolling_window): Before scrolling, turn off a

10214 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10216 Integer and buffer overflow fixes (Bug#8873).
10218 * print.c (printchar, strout): Check for string overflow.
10219 (PRINTPREPARE, printchar, strout):
10220 Don't set size unless allocation succeeds.
10222 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10223 for sizes. Check for string overflow more accurately.
10224 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10226 * macros.c: Integer and buffer overflow fixes.
10227 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10228 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10231 Check for size-calculation overflow.
10232 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10234 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10236 * lread.c: Integer overflow fixes.
10237 (read_integer): Radix is now EMACS_INT, not int,
10238 to improve quality of diagnostics for out-of-range radices.
10239 Calculate buffer size correctly for out-of-range radices.
10240 (read1): Check for integer overflow in radices, and in
10241 read-circle numbers.
10242 (read_escape): Avoid int overflow.
10243 (Fload, openp, read_buffer_size, read1)
10244 (substitute_object_recurse, read_vector, read_list, map_obarray):
10245 Use ptrdiff_t, not int, for sizes.

10260 2011-06-22 Leo Liu <sdl.web@gmail.com>
10262 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10263 Move to minibuffer.el.
10265 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10267 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10268 The following patches are for when GLYPH_DEBUG && !XASSERT.
10269 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10270 * dispnew.c (flush_stdout):
10271 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10272 Mark as externally visible.
10273 * dispnew.c (check_window_matrix_pointers): Now static.
10274 * dispnew.c (window_to_frame_vpos):
10275 * xfns.c (unwind_create_frame):
10276 * xterm.c (x_check_font): Remove unused local.
10277 * scroll.c (CHECK_BOUNDS):
10278 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10279 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10280 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10281 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10282 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10284 (debug_method_add): Use va_list and vsprintf rather than relying
10285 on undefined behavior with wrong number of arguments.
10286 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10287 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10288 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10289 since we're not interested in debugging glyphs with old libraries.
10290 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10291 GCC 4.6.0's static checking.
10293 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10295 Integer overflow and signedness fixes (Bug#8873).

10305 (x_create_bitmap_from_xpm_data):
10306 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10307 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10309 * xfaces.c (load_pixmap):
10310 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10311 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10312 (.bitmaps_last, struct x_output.icon_bitmap):
10313 Use ptrdiff_t, not int, for bitmap indexes.
10314 (x_allocate_bitmap_record): Check for size overflow.
10315 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10317 Use ptrdiff_t, not int, for overlay counts.
10318 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10319 * editfns.c (overlays_around, get_pos_property):
10320 * textprop.c (get_char_property_and_overlay):
10321 * xdisp.c (next_overlay_change, note_mouse_highlight):
10322 * xfaces.c (face_at_buffer_position):
10323 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10324 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10325 (Fnext_overlay_change, Fprevious_overlay_change)
10326 (mouse_face_overlay_overlaps, Foverlays_in):
10327 Use ptrdiff_t, not int, for sizes.
10328 (overlays_at, overlays_in): Check for size-calculation overflow.
10330 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10332 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10333 (x_session_initialize): Do not assume string length fits in int.
10335 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10336 This is unlikely, but can occur if DPI is outlandish.
10338 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10339 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10341 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10342 * xrdb.c (magic_file_p, search_magic_path):
10343 Omit last arg SUFFIX; it was always 0. All callers changed.
10344 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10346 * xfont.c (xfont_match): Avoid need for strlen.
10348 * xfns.c: Don't assume strlen fits in int.
10349 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10351 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10352 not unsigned long, as we prefer signed integers. All callers changed.
10353 Detect integer overflow in repeat count.
10354 (message_dolog): Don't assume print length fits in 39 bytes.
10355 (display_mode_element): Don't assume strlen fits in int.
10357 * termcap.c: Don't assume sizes fit in int and never overflow.
10358 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10359 (gobble_line): Check for size-calculation overflow.
10361 * minibuf.c (Fread_buffer):
10362 * lread.c (intern, intern_c_string):
10363 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10364 Don't assume string length fits in int.
10366 * keyboard.c (parse_tool_bar_item):
10367 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10369 * font.c: Don't assume string length fits in int.

10373 Don't assume integer property fits in fixnum.
10374 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10376 * filelock.c: Fix some buffer overrun and integer overflow issues.
10377 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10378 Reformulate so as not to need the command string.
10379 Invoke gzip -cd rather than gunzip, as it's more portable.
10380 (lock_info_type, lock_file_1, lock_file):
10381 Don't assume pid_t and time_t fit in unsigned long.
10382 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10383 (current_lock_owner): Prefer signed type for sizes.
10384 Use memcpy, not strncpy, where memcpy is what is really wanted.
10385 Don't assume (via atoi) that time_t and pid_t fit in int.
10386 Check for time_t and/or pid_t out of range, e.g., via a network share.
10387 Don't alloca where an auto var works fine.
10389 * fileio.c: Fix some integer overflow issues.
10390 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10391 Don't assume string length fits in int.
10392 (directory_file_name): Don't assume string length fits in long.
10393 (make_temp_name): Don't assume pid fits in int, or that its print
10394 length is less than 20.
10396 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10398 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10400 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10402 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10403 We prefer signed integers, even for size calculations.
10405 * emacs.c: Don't assume string length fits in 'int'.
10406 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10407 (main): Don't invoke strlen when not needed.

10412 * callproc.c (getenv_internal_1, getenv_internal)
10413 (Fgetenv_internal):
10414 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10416 * lread.c (invalid_syntax): Omit length argument.
10417 All uses changed. This doesn't fix a bug, but it simplifies the
10418 code away from its former Hollerith-constant appearance, and it's
10419 one less 'int' to worry about when looking at integer-overflow issues.
10420 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10422 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10423 This didn't break anything, but it didn't help either.
10424 It's confusing to put a bogus integer in a place where the actual
10425 value does not matter.
10426 (LIST_END_P): Remove unused macro and its bogus comment.
10427 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10429 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10430 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10432 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10433 We prefer signed types, and the value cannot exceed the EMACS_INT
10434 range anyway (because otherwise the length would not be representable).
10435 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10436 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10437 This avoids a GCC warning when WIDE_EMACS_INT.
10439 * indent.c (sane_tab_width): New function.
10440 (current_column, scan_for_column, Findent_to, position_indentation)
10441 (compute_motion): Use it. This is just for clarity.
10442 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10444 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10446 * lisp.h (lint_assume): New macro.
10447 * composite.c (composition_gstring_put_cache):
10448 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10450 * editfns.c, insdel.c:
10451 Omit unnecessary forward decls, to simplify future changes.
10453 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10455 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10457 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10458 Use much-faster test for byte-length change.
10459 Don't assume string byte-length fits in 'int'.
10460 Check that character arg fits in 'int'.
10461 (mapcar1): Declare byte as byte, for clarity.
10463 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10465 * fns.c (concat): Catch string overflow earlier.
10466 Do not rely on integer wraparound.
10468 * dispextern.h (struct it.overlay_strings_charpos)
10469 (struct it.selective): Now EMACS_INT, not int.
10470 * xdisp.c (forward_to_next_line_start)
10471 (back_to_previous_visible_line_start)
10472 (reseat_at_next_visible_line_start, next_element_from_buffer):
10473 Don't arbitrarily truncate the value of 'selective' to int.
10475 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10477 * composite.c: Don't truncate sizes to 'int'.
10478 (composition_gstring_p, composition_reseat_it)
10479 (composition_adjust_point): Use EMACS_INT, not int.
10480 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10481 not EMACS_UINT, for indexes.
10483 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10485 * buffer.c: Include <verify.h>.
10486 (struct sortvec.priority, struct sortstr.priority):
10487 Now EMACS_INT, not int.
10488 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10489 (struct sortstr.size, record_overlay_string)
10490 (struct sortstrlist.size, struct sortlist.used):
10491 Don't truncate size to int.
10492 (record_overlay_string): Check for size-calculation overflow.
10493 (init_buffer_once): Check at compile-time, not run-time.
10495 2011-06-22 Jim Meyering <meyering@redhat.com>
10497 Don't leak an XBM-image-sized buffer
10498 * image.c (xbm_load): Free the image buffer after using it.
10500 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10503 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10504 that Sun C diagnosed.
10505 * fns.c (secure_hash): Fix pointer signedness issue.
10506 * intervals.c (static_offset_intervals): New function.
10507 (offset_intervals): Use it.
10509 2011-06-21 Leo Liu <sdl.web@gmail.com>
10512 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10515 * fns.c (secure_hash): Rename from crypto_hash_function and change
10516 the first arg to accept symbols.
10517 (Fsecure_hash): New primitive.
10518 (syms_of_fns): New symbols.
10520 2011-06-20 Deniz Dogan <deniz@dogan.se>
10522 * process.c (Fset_process_buffer): Clarify return value in
10525 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10527 * dispnew.c (add_window_display_history): Use BVAR.
10529 * xdisp.c (debug_method_add): Use BVAR.
10530 (check_window_end, dump_glyph_matrix, dump_glyph)
10531 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10533 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10536 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10537 check till after the cache is created in init_frame_faces.
10539 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10541 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10543 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10545 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10546 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10547 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10549 Improve buffer-overflow checking (Bug#8873).
10550 * fileio.c (Finsert_file_contents):
10551 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10552 Remove the old (too-loose) buffer overflow checks.
10553 They weren't needed, since make_gap checks for buffer overflow.
10554 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10555 The old code merely checked for Emacs fixnum overflow, and relied
10556 on undefined (wraparound) behavior. The new code avoids undefined
10557 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10559 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10560 Tune. Don't use wider integers than needed. Don't use alloca.
10561 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10563 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10565 * insdel.c, lisp.h (buffer_overflow): New function.
10566 (insert_from_buffer_1, replace_range, replace_range_2):
10567 * insdel.c (make_gap_larger):
10568 * editfns.c (Finsert_char):
10569 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10571 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10573 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10575 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10577 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10578 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10580 * fileio.c: Don't assume EMACS_INT fits in off_t.
10581 (emacs_lseek): New static function.
10582 (Finsert_file_contents, Fwrite_region): Use it.
10583 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10585 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10587 * fns.c: Don't overflow int when computing a list length.
10588 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10589 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10590 truncation on 64-bit hosts. Check for QUIT every
10591 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10592 faster and is responsive enough.
10593 (Flength): Report an error instead of overflowing an integer.
10594 (Fsafe_length): Return a float if the value is not representable
10595 as a fixnum. This shouldn't happen except in contrived situations.
10596 (Fnthcdr, Fsort): Don't assume list length fits in int.
10597 (Fcopy_sequence): Don't assume vector length fits in int.
10599 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10600 (header_size, word_size): New constants.
10601 (allocate_vectorlike): Don't check size overflow here.
10602 (allocate_vector): Check it here instead, since this is the only
10603 caller of allocate_vectorlike that could cause overflow.
10604 Check that the new vector's length is representable as a fixnum.
10606 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10607 The previous code was bogus. For example, next_almost_prime (32)
10608 returned 39, which is undesirable as it is a multiple of 3; and
10609 next_almost_prime (24) returned 25, which is a multiple of 5 so
10610 why was the code bothering to check for multiples of 7?
10612 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10614 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10616 Variadic C functions now count arguments with ptrdiff_t.
10617 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10618 Back then I didn't know that the Emacs coding style prefers signed int.
10619 Also, in the meantime I found a few more instances where arguments
10620 were being counted with int, which may truncate counts on 64-bit
10621 machines, or EMACS_INT, which may be unnecessarily wide.
10622 * lisp.h (struct Lisp_Subr.function.aMANY)
10623 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10624 Arg counts are now ptrdiff_t, not size_t.
10625 All variadic functions and their callers changed accordingly.
10626 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10627 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10628 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10629 * callint.c (Fcall_interactively): Check arg count for overflow,
10630 to avoid potential buffer overrun. Use signed char, not 'int',
10631 for 'varies' array, so that we needn't bother to check its size
10632 calculation for overflow.
10633 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10634 * eval.c (apply_lambda):
10635 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10636 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10637 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10639 * callint.c (Fcall_interactively): Don't use index var as event count.
10641 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10642 * mem-limits.h (SIZE): Remove; no longer used.
10644 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10646 Remove unnecessary casts.
10647 * xterm.c (x_term_init):
10648 * xfns.c (x_set_border_pixel):
10649 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10650 These aren't needed now that we assume ANSI C.
10652 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10653 It's more likely to cause problems (due to unsigned overflow)
10656 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10658 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10660 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10662 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10664 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10666 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10668 GLYPH_CODE_FACE returns EMACS_INT, not int.
10669 * dispextern.h (merge_faces):
10670 * xfaces.c (merge_faces):
10671 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10672 Don't assume EMACS_INT fits in int.
10674 * character.h (CHAR_VALID_P): Remove unused parameter.
10675 * fontset.c, lisp.h, xdisp.c: All uses changed.
10677 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10679 * fns.c (concat): Minor tuning based on overflow analysis.
10680 This doesn't fix any bugs. Use int to hold character, instead
10681 of constantly refetching from Emacs object. Use XFASTINT, not
10682 XINT, for value known to be a character. Don't bother comparing
10683 a single byte to 0400, as it's always less.
10685 * floatfns.c (Fexpt):
10686 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10688 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10691 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10693 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10694 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10695 incorrectly succeed when S was a string, because 4294967386 was
10696 truncated before it was used.
10698 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10699 Otherwise, an out-of-range integer could cause undefined behavior
10702 * composite.c: Use int, not EMACS_INT, for characters.
10703 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10704 EMACS_INT, for values that are known to be in character range.
10705 This doesn't fix any bugs but is the usual style inside Emacs and
10706 may generate better code on 32-bit machines.
10708 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10709 This is for reasons similar to the recent CHAR_STRING fix.
10710 * charset.c (Fencode_char): Check that character arg is actually
10711 a character. Pass an int to ENCODE_CHAR.
10712 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10713 wider than 'int', as a compile-time check to prevent future regressions
10716 * character.c (char_string): Remove unnecessary casts.
10718 Make sure a 64-bit char is never passed to CHAR_STRING.
10719 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10720 by silently ignoring the top 32 bits, allowing some values
10721 that were far too large to be valid characters.
10722 * character.h: Include <verify.h>.
10723 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10724 arguments are no wider than unsigned, as a compile-time check
10725 to prevent future regressions in this area.
10727 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10728 (Fsubst_char_in_region):
10730 * xdisp.c (decode_mode_spec_coding):
10731 Adjust to CHAR_STRING's new requirement.
10732 * editfns.c (Finsert_char, Fsubst_char_in_region):
10733 * fns.c (concat): Check that character args are actually
10734 characters. Without this test, these functions did the wrong
10735 thing with wildly out-of-range values on 64-bit hosts.
10737 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10738 These casts should not be needed on 32-bit hosts, either.
10739 * keyboard.c (read_char):
10740 * lread.c (Fload): Remove casts to unsigned.
10742 * lisp.h (UNSIGNED_CMP): New macro.
10743 This fixes comparison bugs on 64-bit hosts.
10744 (ASCII_CHAR_P): Use it.
10745 * casefiddle.c (casify_object):
10746 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10747 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10748 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10749 * dispextern.h (FACE_FROM_ID):
10750 * keyboard.c (read_char): Use UNSIGNED_CMP.
10752 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10753 not to EMACS_INT, to avoid GCC warning.
10755 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10757 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10758 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10759 isn't needed on 32-bit machines.
10761 * buffer.c (Fgenerate_new_buffer_name):
10762 Use EMACS_INT for count, not int.
10763 (advance_to_char_boundary): Return EMACS_INT, not int.
10765 * data.c (Qcompiled_function): Now static.
10767 * window.c (window_body_lines): Now static.
10769 * image.c (gif_load): Rename local to avoid shadowing.
10771 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10772 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10773 * alloc.c (make_save_value): Integer argument is now of type
10774 ptrdiff_t, not int.
10775 (mark_object): Use ptrdiff_t, not int.
10776 * lisp.h (pD): New macro.
10777 * print.c (print_object): Use it.
10779 * alloc.c: Use EMACS_INT, not int, to count objects.
10780 (total_conses, total_markers, total_symbols, total_vector_size)
10781 (total_free_conses, total_free_markers, total_free_symbols)
10782 (total_free_floats, total_floats, total_free_intervals)
10783 (total_intervals, total_strings, total_free_strings):
10784 Now EMACS_INT, not int. All uses changed.
10785 (Fgarbage_collect): Compute overall total using a double, so that
10786 integer overflow is less likely to be a problem. Check for overflow
10787 when converting back to an integer.
10788 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10789 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10790 These were 'int' variables that could overflow on 64-bit hosts;
10791 they were never used, so remove them instead of repairing them.
10792 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10793 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10794 Previously, this ceilinged at INT_MAX, but that doesn't work on
10796 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10798 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10799 (allocate_vectorlike): Check for ptrdiff_t overflow.
10800 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10801 when a (possibly-narrower) signed value would do just as well.
10802 We prefer using signed arithmetic, to avoid comparison confusion.
10804 * alloc.c: Catch some string size overflows that we were missing.
10805 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10806 for convenience in STRING_BYTES_MAX.
10807 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10808 The definition here is exact; the one in lisp.h was approximate.
10809 (allocate_string_data): Check for string overflow. This catches
10810 some instances we weren't catching before. Also, it catches
10811 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10812 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10813 and ptrdiff_t and EMACS_INT are both 64 bits.
10815 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10816 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10817 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10819 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10821 * alloc.c (Fmake_string): Check for out-of-range init.
10823 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10825 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10827 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10829 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10830 xg_get_default_scrollbar_width.
10832 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10833 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10834 (style_changed_cb): Call update_theme_scrollbar_width and call
10835 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10836 all frames (Bug#8505).
10837 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10838 Call gtk_window_set_resizable if HAVE_GTK3.
10839 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10840 and height if HAVE_GTK3 (Bug#8505).
10841 (scroll_bar_width_for_theme): New variable.
10842 (update_theme_scrollbar_width): New function.
10843 (xg_get_default_scrollbar_width): Move code to
10844 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10845 (xg_initialize): Call update_theme_scrollbar_width.
10847 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10849 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10851 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10853 * frame.c (make_frame): Call other_buffer_safely instead of
10856 * window.c (temp_output_buffer_show): Call display_buffer with
10857 second argument Vtemp_buffer_show_specifiers and reset latter
10858 immediately after the call.
10859 (Vtemp_buffer_show_specifiers): New variable.
10860 (auto_window_vscroll_p, next_screen_context_lines)
10861 (Vscroll_preserve_screen_position): Remove leading asterisks from
10864 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10866 Fix minor problems found by GCC 4.6.0 static checking.
10867 * buffer.c (Qclone_number): Remove for now, as it's unused.
10868 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10869 (record_buffer): Remove unused local.
10870 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10871 (set_frame_buffer_list): Remove; unused.
10872 * frame.h (other_visible_frames): Remove decl.
10873 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10874 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10875 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10877 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10878 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10879 Define only if HAVE_GPM.
10880 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10881 (update_hints_inhibit): Remove; never set. All uses removed.
10882 * widgetprv.h (emacsFrameClassRec): Remove decl.
10883 * window.c (delete_deletable_window): Now returns void, since it
10884 wasn't returning anything.
10885 (compare_window_configurations): Remove unused locals.
10886 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10887 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10888 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10889 the same widths as pointers. This follows up on the 2011-05-06 patch.
10890 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10891 * xterm.h: Likewise.
10892 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10894 2011-06-12 Juanma Barranquero <lekktu@gmail.com>

11353 (x_clipboard_manager_save): Add return value.
11354 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
11355 New error handlers.
11356 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
11357 Obey Vx_select_enable_clipboard_manager. Catch errors in
11358 x_clipboard_manager_save (Bug#8779).
11359 (Vx_select_enable_clipboard_manager): New variable.
11360 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11362 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11364 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11366 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11368 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11369 in the current matrix if keep_current_p is non-zero.

11373 * bidi.c (bidi_level_of_next_char): Fix last change.
11375 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11377 Support bidi reordering of text covered by display properties.
11379 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11380 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11381 (bidi_cache_search, bidi_cache_iterator_state)
11382 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11383 (bidi_level_of_next_char, bidi_move_to_visually_next):
11384 Support character positions inside a run of characters covered by a
11386 (bidi_paragraph_init, bidi_resolve_explicit_1)
11387 (bidi_level_of_next_char): Call bidi_fetch_char and
11388 bidi_fetch_char_advance instead of FETCH_CHAR and
11389 FETCH_CHAR_ADVANCE.
11390 (bidi_init_it): Initialize new members.
11391 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11393 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11394 instead of using explicit *_CHAR codes.
11395 (bidi_resolve_explicit, bidi_resolve_weak):
11396 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11397 bidirectional text is supported only in multibyte buffers.
11398 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11399 it to initialize the frame_window_p member of struct bidi_it.
11400 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11401 (bidi_resolve_explicit, bidi_resolve_weak)

11403 bidi_it->nchars is non-positive.
11404 (bidi_level_of_next_char): Don't try to lookup the cache for the
11405 next/previous character if nothing is cached there yet, or if we
11406 were just reseat()'ed to a new position.
11408 * xdisp.c (set_cursor_from_row): Set start and stop points
11409 according to the row's direction when priming the loop that looks
11410 for the glyph on which to display cursor.
11411 (single_display_spec_intangible_p): Function deleted.
11412 (display_prop_intangible_p): Reimplement to call
11413 handle_display_spec instead of single_display_spec_intangible_p.
11414 Accept 3 additional arguments needed by handle_display_spec.
11415 This fixes incorrect cursor motion across display property with complex
11416 values: lists, `(when COND...)' forms, etc.
11417 (single_display_spec_string_p): Support property values that are
11418 lists with the argument STRING its top-level element.
11419 (display_prop_string_p): Fix the condition for processing a
11420 property that is a list to be consistent with handle_display_spec.
11421 (handle_display_spec): New function, refactored from the
11422 last portion of handle_display_prop.
11423 (compute_display_string_pos): Accept additional argument
11424 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11425 value of a `display' property is a "replacing spec".
11426 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11427 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11428 the display property, but just return a value indicating whether
11429 the display property will replace the characters it covers.
11430 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11431 frame_window_p members of struct bidi_it.
11432 (compute_display_string_pos, compute_display_string_end):
11434 (push_it): Accept second argument POSITION, where pop_it should
11435 jump to continue iteration.
11436 (reseat_1): Initialize bidi_it.disp_pos.
11438 * keyboard.c (adjust_point_for_property): Adjust the call to
11439 display_prop_intangible_p to its new signature.
11441 * dispextern.h (struct bidi_it): New member frame_window_p.
11442 (bidi_init_it): Update prototypes.
11443 (display_prop_intangible_p): Update prototype.
11444 (compute_display_string_pos, compute_display_string_end):
11445 Declare prototypes.
11446 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11449 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11451 Malloc failure behavior now depends on size of allocation.
11452 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11453 * lisp.h: Change signatures accordingly.
11454 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11455 All callers changed. (Bug#8762)
11457 * gnutls.c: Use Emacs's memory allocators.
11458 Without this change, the gnutls library would invoke malloc etc.
11459 directly, which causes problems on non-SYNC_INPUT hosts, and which
11460 runs afoul of improving memory_full behavior. (Bug#8761)
11461 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11462 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11463 xfree instead of the default malloc, realloc, free.
11464 (Fgnutls_boot): No need to check for memory allocation failure,
11465 since xmalloc does that for us.
11467 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11468 * category.c (hash_get_category_set):
11469 * ccl.c (ccl_driver):
11470 * charset.c (Fdefine_charset_internal):
11471 * charset.h (struct charset.hash_index):
11472 * composite.c (get_composition_id, gstring_lookup_cache)
11473 (composition_gstring_put_cache):
11474 * composite.h (struct composition.hash_index):
11475 * dispextern.h (struct image.hash):
11476 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11477 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11478 (hashfn_equal, hashfn_user_defined, make_hash_table)
11479 (maybe_resize_hash_table, hash_lookup, hash_put)
11480 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11481 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11482 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11483 * image.c (make_image, search_image_cache, lookup_image)
11484 (xpm_put_color_table_h):
11485 * lisp.h (struct Lisp_Hash_Table):
11486 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11487 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11488 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11489 * alloc.c (allocate_vectorlike):
11490 Check for overflow in vector size calculations.
11491 * ccl.c (ccl_driver):
11492 Check for overflow when converting EMACS_INT to int.
11493 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11494 need to be updated by these changes.
11495 * fns.c (make_hash_table, maybe_resize_hash_table):
11496 Check for integer overflow with large hash tables.
11497 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11498 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11499 (SXHASH_REDUCE): New macro.
11500 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11501 Use it instead of discarding useful hash info with large hash values.
11502 (sxhash_float): New function.
11503 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11504 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11505 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11506 Rewrite to use FIXNUM_BITS, as this simplifies things.
11507 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11508 Adjust signatures to match updated version of code.
11509 (consing_since_gc): Now EMACS_INT, since a single hash table can
11510 use more than INT_MAX bytes.
11512 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11514 Make it possible to build with GCC-4.6+ -O2 -flto.
11516 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11518 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11520 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11521 Call minibuffer-inactive-mode.
11523 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11525 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11526 Update dependencies.
11528 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11530 * data.c (init_data): Remove code for UTS, this system is not
11533 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11535 Don't force ./temacs to start in terminal mode.
11537 * frame.c (make_initial_frame): Initialize faces in all cases, not
11538 only when CANNOT_DUMP is defined.
11539 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11541 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11543 * dispnew.c (add_window_display_history): Use const for the string
11544 pointer. Remove declaration, not needed.
11546 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11548 Use 'inline', not 'INLINE'.
11549 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11550 * alloc.c, fontset.c (INLINE): Remove.
11551 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11552 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11553 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11554 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11555 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11557 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11559 Make it possible to run ./temacs.
11561 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11562 syms_of_callproc does the same thing. Remove test for
11563 "initialized", do it in the caller.
11564 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11566 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11568 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11569 (read_minibuf): Use get_minibuffer.
11570 (syms_of_minibuf): Use DEFSYM.
11571 (Qmetadata): New var.
11572 * data.c (Qbuffer): Don't make it static.
11573 (syms_of_data): Use DEFSYM.
11575 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11577 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11578 (CCL_CODE_MIN): New macro.
11580 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11582 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11584 * eval.c (Qdebug): Now static.
11585 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11586 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11587 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11589 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11591 * image.c: Various fixes to ImageMagick code comments.
11592 (Fimagemagick_types): Doc fix.
11594 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11596 Minor fixes prompted by GCC 4.6.0 warnings.
11598 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11600 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11601 (x_clipboard_manager_save_all): Move extern decl to ...
11602 * xterm.h: ... here, so that it can be checked for consistency.
11604 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11606 * xselect.c (x_clipboard_manager_save_frame)
11607 (x_clipboard_manager_save_all): New functions.
11608 (Fx_clipboard_manager_save): Lisp function deleted.
11610 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11611 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11613 * xterm.h: Update prototype.
11615 2011-05-28 William Xu <william.xwl@gmail.com>
11617 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11618 exiting (Bug#8239).
11620 2011-05-28 Jim Meyering <meyering@redhat.com>
11622 Avoid a sign-extension bug in crypto_hash_function.
11623 * fns.c (to_uchar): Define.
11624 (crypto_hash_function): Use it to convert some newly-signed
11625 variables to unsigned, to avoid sign-extension bugs. For example,
11626 without this change, (md5 "truc") would evaluate to
11627 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11628 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11629 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11631 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11633 Integer overflow fixes.
11635 * dbusbind.c: Serial number integer overflow fixes.
11636 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11637 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11638 to hold a serial number that is too large for a fixnum.
11639 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11640 Check for serial numbers out of range. Decode any serial number
11641 that was so large that it became a float. (Bug#8722)
11643 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11644 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11645 Use XFASTINT rather than XUINT when numbers are nonnegative.
11646 (xd_append_arg, Fdbus_method_return_internal):
11647 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11648 arguments, check that Lisp number is nonnegative, rather than
11649 silently wrapping negative numbers around. (Bug#8722)
11650 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11653 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11655 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11657 ccl: Add integer overflow checks.
11658 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11659 (IN_INT_RANGE): New macros.
11660 (ccl_driver): Use them to check for integer overflow when
11661 decoding a CCL program. Many of the new checks are whether XINT (x)
11662 fits in int; it doesn't always, on 64-bit hosts. The new version
11663 doesn't catch all possible integer overflows, but it's an
11664 improvement. (Bug#8719)
11666 * alloc.c (make_event_array): Use XINT, not XUINT.
11667 There's no need for unsigned here.
11669 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11670 This follows up to the 2011-05-06 change that substituted uintptr_t
11671 for EMACS_INT. This case wasn't caught back then.
11673 Rework Fformat to avoid integer overflow issues.
11674 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11675 now (part of C89). Include <verify.h>.
11676 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11677 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11678 (Fformat): Avoid the prepass trying to compute sizes; it was only
11679 approximate and thus did not catch overflow reliably. Instead, walk
11680 through the format just once, formatting and computing sizes as we go,
11681 checking for integer overflow at every step, and allocating a larger
11682 buffer as needed. Keep track separately whether the format is
11683 multibyte. Keep only the most-recently calculated precision, rather
11684 than them all. Record whether each argument has been converted to
11685 string. Use EMACS_INT, not int, for byte and char and arg counts.
11686 Support field widths and precisions larger than INT_MAX. Avoid
11687 sprintf's undefined behavior with conversion specifications such as %#d
11688 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11689 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11690 formatting out-of-range floating point numbers with int
11691 formats. (Bug#8668)
11693 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11695 * data.c: Avoid integer truncation in expressions involving floats.
11696 * data.c: Include <intprops.h>.
11697 (arith_driver): When there's an integer overflow in an expression
11698 involving floating point, convert the integers to floating point
11699 so that the resulting value does not suffer from catastrophic
11700 integer truncation. For example, on a 64-bit host (* 4
11701 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11702 Do not rely on undefined behavior after integer overflow.
11704 merge count_size_as_multibyte, parse_str_to_multibyte
11705 * character.c, character.h (count_size_as_multibyte):
11706 Rename from parse_str_to_multibyte; all uses changed.
11707 Check for integer overflow.
11708 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11709 since it's now a duplicate of the other. This is more of
11710 a character than a buffer op, so better that it's in character.c.
11711 * fns.c, print.c: Adjust to above changes.
11713 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11715 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11717 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11719 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11720 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11721 (x_clipboard_manager_save): Now static.
11722 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11724 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11725 (crypto_hash_function): Now static.
11726 Fix pointer signedness problems. Avoid unnecessary initializations.
11728 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11730 * termhooks.h (Vselection_alist): Make it terminal-local.
11732 * terminal.c (create_terminal): Initialize it.
11734 * xselect.c: Support for clipboard managers.
11735 (Vselection_alist): Move to termhooks.h as terminal-local var.
11736 (LOCAL_SELECTION): New macro.
11737 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11738 (symbol_to_x_atom): Remove gratuitous arg.
11739 (x_handle_selection_request, lisp_data_to_selection_data)
11740 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11741 (x_own_selection, x_get_local_selection, x_convert_selection):
11742 New arg, specifying work frame. Use terminal-local Vselection_alist.
11743 (some_frame_on_display): Delete unused function.
11744 (Fx_own_selection_internal, Fx_get_selection_internal)
11745 (Fx_disown_selection_internal, Fx_selection_owner_p)
11746 (Fx_selection_exists_p): New optional frame arg.
11747 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11748 (x_handle_selection_clear): Don't treat other terminals with the
11749 same keyboard specially. Use the terminal-local Vselection_alist.
11750 (x_clear_frame_selections): Use Frun_hook_with_args.
11752 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11754 * xterm.h: Add support for those atoms.
11756 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11758 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11759 (converted_selections, conversion_fail_tag): New global variables.
11760 (x_selection_request_lisp_error): Free the above.
11761 (x_get_local_selection): Remove unnecessary code.
11762 (x_reply_selection_request): Args changed; handle arbitrary array
11763 of converted selections stored in converted_selections.
11764 Separate the XChangeProperty and SelectionNotify steps.
11765 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11766 (x_convert_selection): New function.
11767 (x_handle_selection_event): Simplify.
11768 (x_get_foreign_selection): Don't ignore incoming requests while
11769 waiting for an answer; this will fail when we implement
11770 SAVE_TARGETS, and seems unnecessary anyway.
11771 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11772 (Vx_sent_selection_functions): Doc fix.
11774 2011-05-26 Leo Liu <sdl.web@gmail.com>
11776 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11778 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11780 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11782 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11783 for fringe update if it has periodic bitmap.
11784 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11785 and fringe_bitmap_periodic_p.
11787 * fringe.c (get_fringe_bitmap_data): New function.
11788 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11789 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11790 row. Mark glyph row for fringe update if periodicity changed.
11792 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11793 for fringe update unless it has periodic bitmap.
11795 2011-05-25 Kenichi Handa <handa@m17n.org>
11797 * xdisp.c (get_next_display_element): Set correct it->face_id for
11798 a static composition.
11800 2011-05-24 Leo Liu <sdl.web@gmail.com>
11803 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11805 * fns.c (crypto_hash_function, Fsha1): New function.
11806 (Fmd5): Use crypto_hash_function.
11807 (syms_of_fns): Add Ssha1.
11809 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11811 * gnutls.c: Remove unused macros.
11812 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11813 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11814 Remove macros that are defined and never used.
11815 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11817 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11819 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11820 (Fx_get_selection_internal): Minor cleanup.
11821 (Fx_own_selection_internal): Rename arguments for consistency with
11824 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11826 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11828 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11830 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11832 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11834 * dispnew.c (scrolling_window): Don't exclude the case that the
11835 last enabled row in the desired matrix touches the bottom boundary.
11837 2011-05-21 Glenn Morris <rgm@gnu.org>
11839 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11840 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11841 and add some more files.
11843 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11845 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11846 report_file_error introduced by the change from 2011-05-07.
11848 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11850 * systime.h (Time): Define only if emacs is defined.
11851 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11852 where the include path doesn't have X11/X.h by default. See
11853 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11855 2011-05-20 Kenichi Handa <handa@m17n.org>
11857 * composite.c (find_automatic_composition): Fix previous change.
11859 2011-05-20 Glenn Morris <rgm@gnu.org>
11861 * lisp.mk: New file, split from Makefile.in.
11862 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11863 (shortlisp): Remove.
11864 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11866 2011-05-19 Glenn Morris <rgm@gnu.org>
11868 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11869 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11870 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11871 (lisp): Set the order to that of loadup.el.
11872 (shortlisp): Make it a copy of $lisp.
11873 (SOME_MACHINE_LISP): Remove.
11874 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11875 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11877 2011-05-18 Kenichi Handa <handa@m17n.org>
11879 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11880 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11881 (find_automatic_composition): Mostly rewrite for efficiency.
11883 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11885 * makefile.w32-in: Update dependencies.
11887 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11889 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11890 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11892 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11894 Fix some integer overflow issues, such as string length overflow.
11896 * insdel.c (count_size_as_multibyte): Check for string overflow.
11898 * character.c (lisp_string_width): Check for string overflow.
11899 Use EMACS_INT, not int, for string indexes and lengths; in
11900 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11901 the resulting string length overflows an EMACS_INT; instead,
11902 report a string overflow if no precision given. When checking for
11903 precision exhaustion, use a check that cannot possibly have
11904 integer overflow. (Bug#8675)
11905 * character.h (lisp_string_width): Adjust to new signature.
11907 * alloc.c (string_overflow): New function.
11908 (Fmake_string): Use it. This doesn't change behavior, but saves
11909 a few bytes and will simplify future changes.
11910 * character.c (string_escape_byte8): Likewise.
11911 * lisp.h (string_overflow): New decl.
11913 Fixups, following up to the user-interface timestamp change.
11914 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11915 for UI timestamps, instead of unsigned long.
11916 * msdos.c (mouse_get_pos): Likewise.
11917 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11918 * w32gui.h (Time): Define by including "systime.h" rather than by
11919 declaring it ourselves. (Bug#8664)
11921 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11922 * image.c (clear_image_cache): Likewise.
11924 * term.c (term_mouse_position): Don't assume time_t wraparound.
11926 Be more systematic about user-interface timestamps.
11927 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11928 and sometimes 'EMACS_UINT', to represent these timestamps.
11929 This change causes it to use 'Time' uniformly, as that's what X uses.
11930 This makes the code easier to follow, and makes it easier to catch
11931 integer overflow bugs such as Bug#8664.
11932 * frame.c (Fmouse_position, Fmouse_pixel_position):
11933 Use Time, not unsigned long, for user-interface timestamps.
11934 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11935 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11936 * keyboard.h (last_event_timestamp): Likewise.
11937 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11938 * menu.h (xmenu_show): Likewise.
11939 * term.c (term_mouse_position): Likewise.
11940 * termhooks.h (struct input_event.timestamp): Likewise.
11941 (struct terminal.mouse_position_hook): Likewise.
11942 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11943 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11944 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11945 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11946 what it was before.
11947 * menu.h, termhooks.h: Include "systime.h", for Time.
11949 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11950 Don't assume that the difference between two unsigned long values
11951 can fit into an integer. At this point, we know button_down_time
11952 <= event->timestamp, so the difference must be nonnegative, so
11953 there's no need to cast the result if double-click-time is
11954 nonnegative, as it should be; check that it's nonnegative, just in
11955 case. This bug is triggered when events are more than 2**31 ms
11956 apart (about 25 days). (Bug#8664)
11958 * xselect.c (last_event_timestamp): Remove duplicate decl.
11959 (x_own_selection): Remove needless cast to unsigned long.
11961 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11962 that always fit in int. Use a sentinel instead of a counter, to
11963 avoid a temp and to allay GCC's concerns about possible int overflow.
11964 * frame.h (struct frame): Use int for menu_bar_items_used
11965 instead of EMACS_INT, since it always fits in int.
11967 * menu.c (grow_menu_items): Check for int overflow.
11969 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11971 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11972 Before, the code was not consistent. These values cannot exceed
11973 2**31 - 1 so there's no need to make them unsigned.
11974 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11975 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11976 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11978 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11980 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11981 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11982 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11983 presumably because the widths might not match.
11985 * window.c (size_window): Avoid needless test at loop start.
11987 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11989 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11991 2011-05-12 Drew Adams <drew.adams@oracle.com>
11993 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11995 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11997 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11998 `width' to `bar_area_x' and `bar_area_width', respectively.
11999 (x_scroll_run): Take account of fringe background extension.
12001 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12002 Rename local vars `left' and `width' to `bar_area_x' and
12003 `bar_area_width', respectively.
12004 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12005 background extension.
12007 2011-05-10 Jim Meyering <meyering@redhat.com>
12009 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12011 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12013 * image.c (Finit_image_library): Return t for built-in image types,
12014 like pbm and xbm. (Bug#8640)
12016 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12018 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12020 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12022 * w32console.c (Fset_screen_color): Doc fix.
12023 (Fget_screen_color): New function.
12024 (syms_of_ntterm): Defsubr it.
12026 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12027 unlink the temporary file if Fcall_process didn't create it in the
12029 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12030 child process will be redirected to a file specified with `:file'.
12031 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12032 cue to call_process_cleanup not to close that handle.
12034 2011-05-07 Ben Key <bkey76@gmail.com>
12036 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12037 one of two shell specific rules, either bootstrap-temacs-CMD or
12038 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12039 to the previous implementation of the bootstrap-temacs rule.
12040 The bootstrap-temacs-CMD rule is similar to the previous
12041 implementation of the bootstrap-temacs rule except that it
12042 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12045 These changes, along with some changes to nt/configure.bat,
12046 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12047 earlier fix to add support for --cflags and --ldflags options
12048 that include quotes so that it works whether make uses cmd or
12051 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12053 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12054 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12056 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12057 a string. Handle both cases.
12058 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12059 (Fdbus_register_method): Use Qinvalid_function.
12061 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12063 * makefile.w32-in: Update dependencies.
12064 (LISP_H): Add inttypes.h and stdin.h.
12065 (PROCESS_H): Add unistd.h.
12067 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12069 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12070 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12072 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12074 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12076 * term.c (vfatal): Remove stray call to va_end.
12077 It's not needed and the C Standard doesn't allow it here anyway.
12079 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12080 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12082 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12085 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12087 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12089 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12091 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12093 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12095 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12096 * charset.c (Fdefine_charset_internal): Don't initialize
12097 charset.code_space[15]. The value was garbage, on hosts with
12098 32-bit int (Bug#8600).
12100 * lread.c (read_integer): Be more consistent with string-to-number.
12101 Use string_to_number to do the actual conversion; this avoids
12102 rounding errors and fixes some other screwups. Without this fix,
12103 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12104 (digit_to_number): Move earlier, for benefit of read_integer.
12105 Return -1 if the digit is out of range for the base, -2 if it is
12106 not a digit in any supported base. (Bug#8602)
12108 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12110 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12111 to match comment at start of function. This also removes a
12112 GCC warning about overflow in a 32+64-bit port.
12114 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12116 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12117 Reported by Stefan Monnier in
12118 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12119 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12120 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12122 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12123 (EMACS_UINTPTR): Likewise, with uintptr_t.
12125 * lisp.h: Prefer 64-bit EMACS_INT if available.
12126 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12127 on 32-bit hosts that have 64-bit int, so that they can access
12129 However, temporarily disable this change unless the temporary
12130 symbol WIDE_EMACS_INT is defined.
12132 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12134 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12135 This removes an assumption that EMACS_INT and long are the same
12136 width as pointers. The assumption is true for Emacs porting targets
12137 now, but we want to make other targets possible.
12138 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12139 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12140 In the rest of the code, change types of integers that hold casted
12141 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12142 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12143 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12144 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12145 No need to cast type when ORing.
12146 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12147 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12148 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12149 assume EMACS_INT is the same width as char *.
12150 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12151 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12152 Remove no-longer-needed casts.
12153 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12154 (xg_tool_bar_help_callback, xg_make_tool_item):
12155 Use EMACS_INTPTR to hold an integer
12156 that will be cast to void *; this can avoid a GCC warning
12157 if EMACS_INT is not the same width as void *.
12158 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12159 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12160 (current_message_1, set_message_1):
12161 Use a local to convert to proper width without a cast.
12162 * xmenu.c (dialog_selection_callback): Likewise.
12164 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12165 Also, don't assume VALBITS / RAND_BITS is less than 5,
12166 and don't rely on undefined behavior when shifting a 1 left into
12168 * lisp.h (get_random): Change signature to match.
12170 * lread.c (hash_string): Use size_t, not int, for hash computation.
12171 Normally we prefer signed values; but hashing is special, because
12172 it's better to use unsigned division on hash table sizes so that
12173 the remainder is nonnegative. Also, size_t is the natural width
12174 for hashing into memory. The previous code used 'int', which doesn't
12175 retain enough info to hash well into very large tables.
12176 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12178 * dbusbind.c: Don't possibly lose pointer info when converting.
12179 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12180 Use XPNTR rather than XHASH, so that the high-order bits of
12181 the pointer aren't lost when converting through void *.
12183 * eval.c (Fautoload): Don't double-shift a pointer.
12185 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12187 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12189 * gnutls.c (DEF_GNUTLS_FN):
12190 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12192 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12194 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12197 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12199 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12200 New version that can reserve upto 2GB of heap space.
12202 2011-05-05 Chong Yidong <cyd@stupidchicken.com>

12268 * process.c: Include lisp.h before w32.h, not after.
12269 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12270 instead of gnutls_record_check_pending.

12274 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12276 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

12347 %llo or %llx format is passed. (Bug#8545)
12349 * window.c (window_scroll_line_based): Use a marker instead of
12350 simple variables to record original value of point. (Bug#7952)
12352 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12353 produced by %s or %c overflows available buffer space. (Bug#8545)
12355 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12357 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12358 (SIZE_MAX): Move defn after all includes, as they might #define it.
12360 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12362 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12364 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12366 * keyboard.c (Qdelayed_warnings_hook): Define.
12367 (command_loop_1): Run `delayed-warnings-hook'
12368 if Vdelayed_warnings_list is non-nil.
12369 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12370 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12372 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12374 * doprnt.c (doprnt): Don't return value smaller than the buffer
12375 size if the message was truncated. (Bug#8545).
12377 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12379 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12380 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12382 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12384 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12386 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12388 * makefile.w32-in: Update dependencies.
12390 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12392 Improve `doprnt' and its usage. (Bug#8545)
12393 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12394 `format_end'. Remove support for %l as a conversion specifier.
12395 Don't use xrealloc. Improve diagnostics when the %l size modifier
12396 is used. Update the commentary.
12398 * eval.c (verror): Simplify calculation of size_t.
12400 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12403 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12405 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12408 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12410 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12411 This makes this file independent of the recent pseudovector change.
12413 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12415 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12417 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12418 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12419 Remove unused local.
12420 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12422 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12423 GCC 4.6.0 optimizes based on type-based alias analysis.
12424 For example, if b is of type struct buffer * and v of type struct
12425 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12426 != &v->size, and therefore "v->size = 1; b->size = 2; return
12427 v->size;" must therefore return 1. This assumption is incorrect
12428 for Emacs, since it type-puns struct Lisp_Vector * with many other
12429 types. To fix this problem, this patch adds a new type struct
12430 vectorlike_header that documents the constraints on layout of vectors
12431 and pseudovectors, and helps optimizing compilers not get fooled
12432 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12433 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12434 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12436 (XSETPVECTYPE): Rewrite in terms of new macro.
12437 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12438 This is a bit clearer, and further avoids the possibility of
12439 undesirable aliasing.
12440 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12441 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12442 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12443 since Lisp_Subr is a special case (no "next" field).
12444 (ASIZE): Now uses header.size rather than size.
12445 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12446 to avoid the hassle of writing XVECTOR (foo)->header.size.
12447 (struct vectorlike_header): New type.
12448 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12449 object, to help avoid aliasing.
12450 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12451 (SUBRP): Likewise, since Lisp_Subr is a special case.
12452 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12453 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12454 (struct Lisp_Hash_Table): Combine first two members into a single
12455 struct vectorlike_header member. All uses of "size" and "next" members
12456 changed to be "header.size" and "header.next".
12457 * buffer.h (struct buffer): Likewise.
12458 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12459 * frame.h (struct frame): Likewise.
12460 * process.h (struct Lisp_Process): Likewise.
12461 * termhooks.h (struct terminal): Likewise.
12462 * window.c (struct save_window_data, struct saved_window): Likewise.
12463 * window.h (struct window): Likewise.
12464 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12465 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12466 * buffer.c (init_buffer_once): Likewise.
12467 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12469 * process.c (Fformat_network_address): Use local var for size,
12472 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12474 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12475 * data.c (atof): Remove decl; no longer used or needed.
12476 (digit_to_number): Move to lread.c.
12477 (Fstring_to_number): Use new string_to_number function, to be
12478 consistent with how the Lisp reader treats infinities and NaNs.
12479 Do not assume that floating-point numbers represent EMACS_INT
12480 without losing information; this is not true on most 64-bit hosts.
12481 Avoid double-rounding errors, by insisting on integers when
12482 parsing non-base-10 numbers, as the documentation specifies.
12483 * lisp.h (string_to_number): New decl, replacing ...
12484 (isfloat_string): Remove.
12485 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12486 (read1): Do not accept +. and -. as integers; this
12487 appears to have been a coding error. Similarly, do not accept
12488 strings like +-1e0 as floating point numbers. Do not report
12489 overflow for integer overflows unless the base is not 10 which
12490 means we have no simple and reliable way to continue.
12491 Break out the floating-point parsing into a new
12492 function string_to_number, so that Fstring_to_number parses
12493 floating point numbers consistently with the Lisp reader.
12494 (digit_to_number): Move here from data.c. Make it static inline.
12495 (E_CHAR, EXP_INT): Remove, replacing with ...
12496 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12497 (string_to_number): New function, replacing isfloat_string.
12498 This function checks for valid syntax and produces the resulting
12499 Lisp float number too. Rework it so that string-to-number
12500 no longer mishandles examples like "1.0e+". Use strtoumax,
12501 so that overflow for non-base-10 numbers is reported only when
12502 there's no portable and simple way to convert to floating point.
12504 * textprop.c (set_text_properties_1): Rewrite for clarity,
12505 and to avoid GCC warning about integer overflow.
12507 * intervals.h (struct interval): Use EMACS_INT for members
12508 where EMACS_UINT might cause problems. See
12509 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12510 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12511 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12513 (offset_intervals): Tell GCC not to worry about length overflow
12514 when negating a negative length.
12516 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12517 (overrun_check_free): Likewise.
12519 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12520 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12523 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12524 (gnutls_make_error): Rename local to avoid shadowing.
12525 (gnutls_emacs_global_deinit): ifdef out; not used.
12526 (Fgnutls_boot): Use const for pointer to readonly storage.
12527 Comment out unused local. Fix pointer signedness problems.
12529 * lread.c (openp): Don't stuff size_t into an 'int'.
12530 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12531 about possible signed overflow.
12533 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12534 (GDK_KEY_g): Don't define if already defined.
12535 (xg_prepare_tooltip): Avoid pointer signedness problem.
12536 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12538 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12539 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12541 * xfns.c (Fx_window_property): Simplify a bit,
12542 to make a bit faster and to avoid GCC 4.6.0 warning.
12543 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12545 * fns.c (internal_equal): Don't assume size_t fits in int.
12547 * alloc.c (compact_small_strings): Tighten assertion a little.
12549 Replace pEd with more-general pI, and fix some printf arg casts.
12550 * lisp.h (pI): New macro, generalizing old pEd macro to other
12551 conversion specifiers. For example, use "...%"pI"d..." rather
12552 than "...%"pEd"...".
12553 (pEd): Remove. All uses replaced with similar uses of pI.
12554 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12555 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12556 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12557 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12558 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12559 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12560 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12562 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12563 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12564 * print.c (safe_debug_print, print_object): Likewise.
12565 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12567 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12568 avoiding the 0 flag, which is not portable.
12569 * process.c (Fmake_network_process): Use pI to avoid cast.
12570 * region-cache.c (pp_cache): Likewise.
12571 * xdisp.c (decode_mode_spec): Likewise.
12572 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12573 behavior on 64-bit hosts with printf arg.
12574 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12575 (x_stop_queuing_selection_requests): Likewise.
12576 (x_get_window_property): Don't truncate byte count to an 'int'
12579 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12580 here, since it parses constructs like leading '-' and spaces,
12581 which are not wanted; and it overflows with large numbers.
12582 Instead, simply match F[0-9]+, which is what is wanted anyway.
12584 * alloc.c: Remove unportable assumptions about struct layout.
12585 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12586 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12587 (allocate_vectorlike, make_pure_vector): Use the new macros,
12588 plus offsetof, to remove unportable assumptions about struct layout.
12589 These assumptions hold on all porting targets that I know of, but
12590 they are not guaranteed, they're easy to remove, and removing them
12591 makes further changes easier.
12593 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12594 This doesn't fix a bug but makes the code clearer.
12595 (string_overrun_cookie): Now const. Use initializers that
12596 don't formally overflow signed char, to avoid warnings.
12597 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12598 can cause Emacs to crash when string overrun checking is enabled.
12599 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12600 multiple of sizeof (EMACS_INT); it need not be, if
12601 alignof(EMACS_INT) < sizeof (EMACS_INT).
12602 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12604 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12606 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12608 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12610 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12611 supposed to be handshaking. (Bug#8556)
12612 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12614 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12616 * lisp.h (Qdebug): List symbol.
12617 * eval.c (Qdebug): Restore global linkage.
12618 * keyboard.c (debug-on-event): New variable.

13185 * xfaces.c (face_at_string_position):
13186 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

13373 Make Emacs functions such as Fatom 'static' by default.

13375 to see whether these functions can be called from other modules.
13376 DEFUN now defines a static function. To make the function external
13377 so that it can be used in other C modules, use the new macro DEFUE.

13453 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13455 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13456 since callers should never pass a negative size.
13457 Change the signature to match that of plain 'read' and 'write'; see
13458 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13459 * lisp.h: Update prototypes of emacs_write and emacs_read.
13461 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13463 * xdisp.c (redisplay_window): Don't try to determine the character
13464 position of the scroll margin if the window start point w->startp
13465 is outside the buffer's accessible region. (Bug#8468)
13467 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13469 Fix write-region and its subroutines for buffers > 2GB.
13470 * fileio.c (a_write, e_write): Modify declaration of arguments and
13471 local variables to support buffers larger than 2GB.
13472 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13474 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13475 argument, local variables, and return value.
13477 * lisp.h: Update prototypes of emacs_write and emacs_read.
13479 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13481 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13483 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13485 Fix more problems found by GCC 4.6.0's static checks.
13487 * xdisp.c (vmessage): Use a better test for character truncation.
13489 * charset.c (load_charset_map): <, not <=, for optimization,

13499 * callint.c (Fcall_interactively): <, not <=, for optimization.
13500 (Fcall_interactively): Count the number of arguments produced,
13501 not the number of arguments given. This is simpler and lets GCC
13502 4.6.0 generate slightly better code.
13504 * ftfont.c: Distingish more carefully between FcChar8 and char.
13505 The previous code passed unsigned char * to a functions like
13506 strlen and xstrcasecmp that expect char *, which does not
13507 conform to the C standard.
13508 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13509 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13510 char * when the C standard requires it.
13512 * keyboard.c (read_char): Remove unused var.
13514 * eval.c: Port to Windows vsnprintf (Bug#8435).
13515 Include <limits.h>.
13516 (SIZE_MAX): Define if the headers do not.
13517 (verror): Do not give up if vsnprintf returns a negative count.
13518 Instead, grow the buffer. This ports to Windows vsnprintf, which
13519 does not conform to C99. Problem reported by Eli Zaretskii.
13520 Also, simplify the allocation scheme, by avoiding the need for
13521 calling realloc, and removing the ALLOCATED variable.
13523 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13525 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13526 But keep the doprint source code for now, as we might revamp it
13527 and use it again (Bug#8435).
13528 * lisp.h (doprnt): Remove.
13529 * Makefile.in (base_obj): Remove doprnt.o.
13530 * deps.mk (doprnt.o): Remove.
13532 error: Print 32- and 64-bit integers portably (Bug#8435).
13533 Without this change, on typical 64-bit hosts error ("...%d...", N)
13534 was used to print both 32- and 64-bit integers N, which relied on
13535 undefined behavior.
13536 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13537 * lisp.h (error, verror): Mark as printf-like functions.
13538 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13539 Report overflow in size calculations when allocating printf buffer.
13540 Do not truncate output string at its first null byte.
13541 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13542 Truncate the output at a character boundary, since vsnprintf does not
13544 * charset.c (check_iso_charset_parameter): Convert internal
13545 character to string before calling 'error', since %c now has the
13547 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13548 overflow when computing char to be passed to 'error'. Do not
13549 pass Lisp_Object to 'error'; pass the integer instead.
13550 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13551 formatted with plain %d.
13553 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13555 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13557 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13559 * xterm.c (x_catch_errors): Remove duplicate declaration.
13561 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13563 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13565 2011-04-10 Jim Meyering <meyering@redhat.com>
13567 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13568 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13569 return ssize_t not "int", and use size_t as the buffer length.
13570 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13571 * gnutls.h: Update declarations.
13572 * process.c (read_process_output): Use ssize_t, to match.
13573 (send_process): Likewise.

13577 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13579 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13581 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13582 Use unsigned char, to match FcChar8 type definition.
13584 * xterm.c (handle_one_xevent):
13585 * xmenu.c (create_and_show_popup_menu):
13586 * xselect.c (x_decline_selection_request)
13587 (x_reply_selection_request): Avoid type-punned deref of X events.
13589 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13591 Fix some uses of `int' instead of EMACS_INT.
13592 * search.c (string_match_1, fast_string_match)

13596 (Fmatch_data): Make some `int' variables be EMACS_INT.
13598 * xdisp.c (display_count_lines): 3rd argument and return value now
13599 EMACS_INT. All callers changed.
13600 (pint2hrstr): Last argument is now EMACS_INT.
13602 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)

13615 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13616 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13618 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13619 (encode_invocation_designation): Last argument P_NCHARS is now
13621 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13622 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13624 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13627 * ccl.c (Fccl_execute_on_string): Declare some variables
13630 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

13645 instead of using internal_with_output_to_temp_buffer.
13646 (Qhelp_form_show): New var.
13647 (syms_of_keyboard): Use DEFSYM macro.
13649 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13683 to system-supplied API.
13685 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13687 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13688 This avoids several warnings with gcc -Wstrict-overflow.
13689 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13690 directly, rather than having caller test rule sign. This avoids
13691 some unnecessary tests.
13692 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13693 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13694 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13696 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13697 (xfont_open): Avoid unnecessary tests.
13699 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13701 * composite.h, composite.c (composition_gstring_put_cache):
13702 Use EMACS_INT, not int, for length.

13705 breaking out part of COMPOSITION_DECODE_RULE.
13706 (COMPOSITION_DECODE_RULE): Use it.

13708 by using the new macro.
13710 * textprop.c (set_text_properties_1): Change while to do-while,
13711 since the condition is always true at first.
13713 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13714 (interval_deletion_adjustment): Return unsigned value.
13717 * process.c (list_processes_1, create_pty, read_process_output):

13733 * print.c (print_error_message): Avoid int overflow.
13735 * font.c (font_list_entities): Redo for clarity,
13736 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13738 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13739 (font_score): Avoid potential overflow in diff calculation.
13741 * fns.c (substring_both): Remove var that is set but not used.
13742 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13744 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13746 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13747 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13748 can always succeed if overflow has undefined behavior.
13750 * search.c (boyer_moore, wordify): Remove vars set but not used.
13751 (wordify): Omit three unnecessary tests.
13753 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13754 All callers changed. This avoids the need for an unused var.
13756 * casefiddle.c (casify_region): Remove var that is set but not used.
13758 * dired.c (file_name_completion): Remove var that is set but not used.
13760 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13762 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13763 (Finsert_file_contents): Remove unnecessary code checking fd.
13765 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13766 Check for integer overflow on size calculations.
13768 * buffer.c (Fprevious_overlay_change): Remove var that is set
13771 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13772 Remove vars that are set but not used.
13773 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13774 (timer_check_2): Mark vars as initialized.
13776 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13778 * image.c (lookup_image): Remove var that is set but not used.
13779 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13781 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13782 that are set but not used.
13784 * xfns.c (make_invisible_cursor): Don't return garbage
13785 if XCreateBitmapFromData fails (Bug#8410).
13787 * xselect.c (x_get_local_selection, x_handle_property_notify):
13788 Remove vars that are set but not used.
13790 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13791 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13793 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13794 Remove var that is set but not used.
13795 (scroll_bar_windows_size): Now size_t, not int.
13796 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13797 Check for overflow.
13799 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13800 (map_tty_color) [!defined MSDOS]: Likewise.
13802 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13804 * coding.c: Remove vars that are set but not used.
13805 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13806 All callers changed.

13808 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13809 (decode_coding_charset): Remove vars that are set but not used.
13811 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13812 that is set but not used.
13814 * print.c (print_object): Remove var that is set but not used.
13816 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13817 The gnulib version avoids calling malloc in the usual case,
13818 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13819 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13820 * filelock.c (current_lock_owner): Likewise.
13821 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13822 * sysdep.c: Include allocator.h, careadlinkat.h.
13823 (emacs_no_realloc_allocator): New static constant.
13824 (emacs_readlink): New function.
13825 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13826 ../lib/careadlinkat.h.
13828 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13830 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13831 first non-nil return value).
13833 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13835 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13836 if not defined (Bug#8403).

13845 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13846 and thereabouts. All callers changed.
13847 (get_per_char_metric): Remove parameter `f', unused since
13848 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13850 2011-04-02 Jim Meyering <meyering@redhat.com>
13852 do not dereference NULL upon failed strdup
13853 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13854 (ns_get_family): Likewise.
13856 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13858 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13860 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13862 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

13880 (syms_of_lread): Declare `lexical-binding'.
13882 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13884 * keyboard.c (eval_dyn): New fun.
13885 (menu_item_eval_property): Use it.
13887 * image.c (parse_image_spec): Use Ffunctionp.
13889 * fns.c (concat, mapcar1): Accept byte-code-functions.
13891 * eval.c (Fsetq): Handle lexical vars.
13892 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13893 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13894 (FletX, Flet): Obey lexical binding.
13895 (Fcommandp): Handle closures.
13896 (Feval): New `lexical' arg.
13897 (eval_sub): New function extracted from Feval. Use it almost
13898 everywhere where Feval was used. Look up vars in lexical env.
13900 (Ffunctionp): Move from subr.el.
13901 (Ffuncall): Handle closures.
13902 (apply_lambda): Remove `eval_flags'.
13903 (funcall_lambda): Handle closures and new byte-code-functions.
13904 (Fspecial_variable_p): New function.
13905 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13906 but without exporting it to Lisp.
13908 * doc.c (Fdocumentation, store_function_docstring):
13909 * data.c (Finteractive_form): Handle closures.
13911 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13914 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13916 (exec_byte_code): New function extracted from Fbyte_code to handle new
13917 calling convention for byte-code-functions. Add new byte-codes.
13919 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13921 * alloc.c (Fmake_symbol): Init new `declared_special' field.

13929 * xdisp.c (SCROLL_LIMIT): New macro.
13930 (try_scrolling): Use it when setting scroll_limit.
13931 Limit scrolling to 100 screen lines.
13932 (redisplay_window): Even when falling back on "recentering",
13933 position point in the window according to scroll-conservatively,
13934 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13936 (try_scrolling): When point is above the window, allow searching
13937 as far as scroll_max, or one screenful, to compute vertical
13938 distance from PT to the scroll margin position. This prevents
13939 try_scrolling from unnecessarily failing when
13940 scroll-conservatively is set to a value slightly larger than the
13941 window height. Clean up the case of PT below the margin at bottom
13942 of window: scroll_max can no longer be INT_MAX. When aggressive
13943 scrolling is in use, don't let point enter the opposite scroll
13944 margin as result of the scroll.
13945 (syms_of_xdisp) <scroll-conservatively>: Document the
13946 threshold of 100 lines for never-recentering scrolling.

13953 (message_log_check_duplicate): Remove parameters `prev_bol' and
13954 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13955 (redisplay_internal): Remove parameter `preserve_echo_area',
13956 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13958 * indent.c (Fvertical_motion):
13959 * window.c (window_scroll_pixel_based, Frecenter):
13960 Don't pass `need_y_p' to `move_it_by_lines'.
13962 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13964 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13965 steal a few bits to be more compact.
13966 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13967 Remove unneeded casts.
13969 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13971 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13973 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13974 binding" message (bug#7967).
13976 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13978 Fix more problems found by GCC 4.6.0's static checks.
13980 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13981 Remove unused local var.
13983 * editfns.c (Fmessage_box): Remove unused local var.
13985 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13986 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13987 Omit unused local vars.
13988 * window.c (shrink_windows): Omit unused local var.
13989 * menu.c (digest_single_submenu): Omit unused local var.
13990 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13991 Omit unused local var.
13993 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13994 Don't assume string length fits in int.
13995 (keyremap_step, read_key_sequence): Use size_t for sizes.
13996 (read_key_sequence): Don't check last_real_key_start redundantly.
13998 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13999 instead of alloca (Bug#8344).
14001 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14002 (Fbacktrace_frame): Don't assume nframes fits in int.
14004 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14006 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14009 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14011 * cm.c (calccost): Turn while-do into do-while, for clarity.
14013 * keyboard.c (syms_of_keyboard): Use the same style as later
14014 in this function when indexing through an array. This also
14015 works around GCC bug 48267.
14017 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14019 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

14022 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14024 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14025 This avoids undefined behavior on integer overflow, and is a bit
14026 more convenient anyway since it is compared to a size_t variable.
14028 Variadic C functions now count arguments with size_t, not int.
14029 This avoids an unnecessary limitation on 64-bit machines, which
14030 caused (substring ...) to crash on large vectors (Bug#8344).
14031 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14032 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14033 All variadic functions and their callers changed accordingly.
14034 (struct gcpro.nvars): Now size_t, not int. All uses changed.

14036 * editfns.c (general_insert_function): Likewise.
14037 * eval.c (struct backtrace.nargs, interactive_p)
14038 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14039 (funcall_lambda, mark_backtrace): Likewise.
14040 * fns.c (concat): Likewise.
14041 * frame.c (x_set_frame_parameters): Likewise.
14042 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14043 0 if not found, not -1. All callers changed.
14045 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14046 (stack_copy_size): Now size_t, not int.
14047 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

14052 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14053 All callers changed.
14055 * lisp.h (multibyte_char_to_unibyte):
14056 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14057 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14058 * character.h (CHAR_TO_BYTE8):
14059 * cmds.c (internal_self_insert):
14060 * editfns.c (general_insert_function):
14061 * keymap.c (push_key_description):
14062 * search.c (Freplace_match):
14063 * xdisp.c (message_dolog, set_message_1): All callers changed.
14065 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14067 * keyboard.c (safe_run_hook_funcall): New function.
14068 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14069 don't set the hook to nil, but remove the offending function instead.
14070 (Qcommand_hook_internal): Remove, unused.
14071 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14072 Vcommand_hook_internal.
14074 * eval.c (enum run_hooks_condition): Remove.
14075 (funcall_nil, funcall_not): New functions.
14076 (run_hook_with_args): Call each function through a `funcall' argument.
14077 Remove `cond' argument, now redundant.
14078 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14079 (Frun_hook_with_args_until_failure): Adjust accordingly.
14080 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14082 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14084 * dispextern.h (string_buffer_position): Remove declaration.
14086 * print.c (strout): Remove parameter `multibyte', unused since
14087 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14089 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14090 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14091 All callers changed.
14093 * w32.c (_wsa_errlist): Use braces for struct initializers.

14096 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14097 All callers changed.
14098 (string_buffer_position): Likewise. Also, make static (it's never
14099 used outside xdisp.c).

14103 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14104 All callers changed.
14106 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14108 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14119 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14121 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14123 * nsmenu.m (runDialogAt): Remove argument to timer_check.
14125 2011-03-27 Glenn Morris <rgm@gnu.org>

14128 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
14129 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
14130 Replace SIGTYPE with void everywhere.

14134 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14136 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14137 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14139 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14141 * w32.c (read_unc_volume): Use parameter `henum', instead of
14142 global variable `wget_enum_handle'.
14144 * keymap.c (describe_vector): Remove parameters `indices' and
14145 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14160 * gtkutil.c (xg_maybe_add_timer):
14161 * keyboard.c (readable_events):
14162 * process.c (wait_reading_process_output):
14163 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14165 * insdel.c (adjust_markers_gap_motion):
14166 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

14240 2011-03-23 Julien Danjou <julien@danjou.info>
14242 * term.c (Fsuspend_tty, Fresume_tty):
14243 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14244 * window.c (temp_output_buffer_show):
14245 * insdel.c (signal_before_change):
14246 * frame.c (Fhandle_switch_frame):
14247 * fileio.c (Fdo_auto_save):
14248 * emacs.c (Fkill_emacs):
14249 * editfns.c (save_excursion_restore):
14250 * cmds.c (internal_self_insert):
14251 * callint.c (Fcall_interactively):
14252 * buffer.c (Fkill_all_local_variables):
14253 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14255 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14256 unconditionally since it does the check itself.
14258 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14260 Fix more problems found by GCC 4.5.2's static checks.
14262 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14263 the first time through the loop, since we know p0 < p1 then.
14264 This also avoids a gcc -Wstrict-overflow warning.
14266 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14267 leading to a memory leak, possible in functions like
14268 load_charset_map_from_file that can allocate an unbounded number
14269 of objects (Bug#8318).
14271 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14272 that could (at least in theory) be that large.
14274 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14275 This is less likely to overflow, and avoids undefined behavior if
14276 overflow does occur. All callers changed. Use strtoul to scan
14277 for the unsigned long integer.
14278 (pint2hrstr): Simplify and tune code slightly.
14279 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14287 This also avoids a warning with gcc -Wstrict-overflow.
14289 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14292 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14294 * process.c (Fmake_network_process): Use socklen_t, not int,
14295 where POSIX says socklen_t is required in portable programs.
14296 This fixes a porting bug on hosts like 64-bit HP-UX, where
14297 socklen_t is wider than int (Bug#8277).
14298 (Fmake_network_process, server_accept_connection):
14299 (wait_reading_process_output, read_process_output):
14302 * process.c: Rename or move locals to avoid shadowing.
14303 (list_processes_1, Fmake_network_process):
14304 (read_process_output_error_handler, exec_sentinel_error_handler):
14305 Rename or move locals.
14306 (Fmake_network_process): Define label "retry_connect" only if needed.
14307 (Fnetwork_interface_info): Fix pointer signedness.
14308 (process_send_signal): Add cast to avoid pointer signedness problem.
14309 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14310 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14312 Make tparam.h and terminfo.c consistent.
14313 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14314 Include tparam.h instead, since it declares them.
14315 * cm.h (PC): Remove extern decl; tparam.h now does this.
14316 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14317 * terminfo.c: Include tparam.h, to check interfaces.
14318 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14319 (tparam): Adjust signature to match interface in tparam.h;
14320 this removes some undefined behavior. Check that outstring and len
14321 are zero, which they always are with Emacs.
14322 * tparam.h (PC, BC, UP): New extern decls.
14324 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14325 (xftfont_open): Rename locals to avoid shadowing.
14327 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14328 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14329 (OTF_TAG_SYM): Omit macro if not needed.
14330 (ftfont_list): Remove unused local.
14331 (get_adstyle_property, ftfont_pattern_entity):
14332 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14333 Rename locals to avoid shadowing.
14335 * xfont.c (xfont_list_family): Mark var as initialized.
14337 * xml.c (make_dom): Now static.
14339 * composite.c (composition_compute_stop_pos): Rename local to
14341 (composition_reseat_it): Remove unused locals.
14342 (find_automatic_composition, composition_adjust_point): Likewise.
14343 (composition_update_it): Mark var as initialized.
14344 (find_automatic_composition): Mark vars as initialized,
14345 with a FIXME (Bug#8290).
14347 character.h: Rename locals to avoid shadowing.
14348 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14349 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14350 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14351 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14352 to avoid shadowing.
14354 * textprop.c (property_change_between_p): Remove; unused.
14356 * intervals.c (interval_start_pos): Now static.
14358 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
14360 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
14361 Rename locals to avoid shadowing.
14363 * sound.c (wav_play, au_play, Fplay_sound_internal):
14364 Fix pointer signedness.
14365 (alsa_choose_format): Remove unused local var.
14366 (wav_play): Initialize a variable to 0, to prevent undefined
14367 behavior (Bug#8278).
14369 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14371 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14373 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14374 clobbering (Bug#8298).
14375 * sysdep.c (sys_subshell): Likewise.
14376 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14378 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14379 This should get cleaned up, so that child_setup has the
14380 same signature on all platforms.
14382 * callproc.c (call_process_cleanup): Now static.
14383 (relocate_fd): Rename locals to avoid shadowing.
14385 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14387 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14388 not to be necessary, and produces flickering.
14390 2011-03-20 Glenn Morris <rgm@gnu.org>
14392 * config.in: Remove file.
14394 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14396 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14397 are now in src/globals.h.
14398 (syms_of_minibuf): Remove spurious & from previous change.

14498 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
14499 (Fdefvar): Rewrite so as not to use empty "else".

14513 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14514 some of which prompt warnings from gcc -Wbad-function-cast.
14515 (Fformat_time_string, Fencode_time, Finsert_char):

14549 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14551 Use functions, not macros, for up- and down-casing (Bug#8254).
14552 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14553 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14554 to use the following functions instead of these macros.
14555 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14556 EMACS_INT, since callers assume the returned value fits in int.
14557 (upcase1): Likewise, for UPCASE_TABLE.
14558 (uppercasep, lowercasep, upcase): New static inline functions.
14559 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14568 which gcc can warn about.
14569 (regex_compile, re_match_2_internal): Mark locals as initialized.
14570 (RETALLOC_IF): Define only if needed.
14571 (WORDCHAR_P): Likewise. This one is never needed, but is used
14572 only in a comment talking about a compiler bug, so put inside
14573 the #if 0 of that comment.
14574 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14575 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14578 * search.c (boyer_moore): Rename locals to avoid shadowing.

14593 Rename locals to avoid shadowing.
14594 (Fvertical_motion): Mark locals as initialized.
14596 * casefiddle.c (casify_object, casify_region): Now static.
14597 (casify_region): Mark local as initialized.

14601 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14602 New macros, so that the caller can use some names other than
14603 gcpro1, gcpro2, etc.
14604 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14606 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14607 argument, for consistency with GCPRO2_VAR, etc: it is now the
14608 prefix of the variable, not the variable itself. All uses
14610 * dired.c (directory_files_internal, file_name_completion):
14611 Rename locals to avoid shadowing.
14613 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14614 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14615 dired.c's scmp function, had undefined behavior.
14616 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14617 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14618 * buffer.h: ... to here, because these macros use current_buffer,
14619 and the new implementation with inline functions needs to have
14620 current_buffer in scope now, rather than later when the macros
14622 (downcase, upcase1): New static inline functions.
14623 (DOWNCASE, UPCASE1): Reimplement using these functions.
14624 This avoids undefined behavior in expressions like
14625 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14626 from race conditions in accessing the global variables
14627 case_temp1 and case_temp2.
14628 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14629 * lisp.h (case_temp1, case_temp2): Remove their decls.
14630 * character.h (ASCII_CHAR_P): Move from here ...
14631 * lisp.h: ... to here, so that the inline functions mentioned
14632 above can use them.
14634 * dired.c (directory_files_internal_unwind): Now static.
14636 * fileio.c (file_name_as_directory, directory_file_name):
14637 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14639 (file_name_as_directory): Use const pointers when appropriate.
14640 (Fexpand_file_name): Likewise. In particular, newdir might
14641 point at constant storage, so make it a const pointer.
14642 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14643 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14645 (Fset_file_times, Finsert_file_contents, auto_save_error):

14649 (Ftry_completion, Fall_completions): Rename or remove locals
14650 to avoid shadowing.
14652 * marker.c (bytepos_to_charpos): Remove; unused.
14654 * lisp.h (verify_bytepos, count_markers): New decls,
14655 so that gcc does not warn that these functions aren't declared.
14657 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14658 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14659 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14660 (copy_text): Remove unused local var.
14662 * filelock.c (within_one_second): Now static.
14663 (lock_file_1): Rename local to avoid shadowing.
14665 * buffer.c (fix_overlays_before): Mark locals as initialized.
14666 (fix_start_end_in_overlays): Likewise. This function should be
14667 simplified by using pointers-to-pointers, but that's a different
14669 (switch_to_buffer_1): Now static.
14670 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14671 (report_overlay_modification): Rename locals to avoid shadowing.
14673 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14674 Fix pointer signedness issue.
14675 (sys_subshell): Mark local as volatile if checking for lint,
14676 to suppress a gcc -Wclobbered warning that does not seem to be right.
14677 (MAXPATHLEN): Define only if needed.
14679 * process.c (serial_open, serial_configure): Move decls from here ...
14680 * systty.h: ... to here, so that they can be checked.
14682 * fns.c (get_random, seed_random): Move extern decls from here ...
14683 * lisp.h: ... to here, so that they can be checked.
14685 * sysdep.c (reset_io): Now static.
14686 (wait_for_termination_signal): Remove; unused.
14688 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14689 (copy_keymap_item, append_key, push_text_char_description):
14691 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14692 (DENSE_TABLE_SIZE): Remove; unused.
14693 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14694 (describe_map_tree):
14695 Rename locals to avoid shadowing.
14697 * keyboard.c: Declare functions static if they are not used elsewhere.
14698 (echo_char, echo_dash, cmd_error, top_level_2):
14699 (poll_for_input, handle_async_input): Now static.
14700 (read_char, kbd_buffer_get_event, make_lispy_position):
14701 (make_lispy_event, make_lispy_movement, apply_modifiers):
14702 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
14703 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
14704 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
14705 (read_key_sequence, read_char): Mark locals as initialized.

14719 if GCC considers string literals to be constants.
14721 * lisp.h (fatal_error_signal): Add decl, since it's exported.

14782 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
14783 These macros can no longer be used for assignment.
14785 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

14841 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
14843 Improve quality of tests for time stamp overflow.
14844 For example, without this patch (encode-time 0 0 0 1 1
14845 1152921504606846976) returns the obviously-bogus value (-948597
14846 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14847 reports time overflow. See
