183 * w32.c (init_environment): Change the default values of many
184 environment variables in dflt_envvars[] to NULL, to avoid pushing
185 them into environment when they were not already defined. Remove
186 the code that deletes site-lisp subdirectories from the default
187 value of EMACSLOADPATH, as it is no longer needed.
188 (check_windows_init_file): Now external, not static. Use
189 Vload_path as is, without adding anything, as this function is now
190 called when Vload_path is already set up.
192 * w32.h (check_windows_init_file): Add prototype.
194 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

200 any, in the DEFALT argument into the root of the Emacs build or
201 installation tree, as appropriate.
203 * callproc.c (init_callproc_1): Call decode_env_path instead of
204 doing its equivalent by hand.
205 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
206 the code that sets Vexec_path run on MS-Windows.
208 * lread.c (init_lread): Add comments to #ifdef's.
210 * msdos.c (dos_set_window_size, IT_update_begin)

237 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
238 Remove unnecessary pointer casts.
239 * alloc.c (record_xmalloc): New function.
240 * lisp.h (record_xmalloc): New decl.
241 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
242 more like a function. This is because the pointer cast is not
243 needed. All uses changed.
244 * print.c (print_string, print_error_message): Avoid length recalc.
246 Improve fix for macroexp crash with debugging (Bug#12118).
247 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
248 ARRAY_MARK_FLAG when checking subscripts, because ASET is
249 not supposed to be invoked from the garbage collector.
250 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
251 (gc_aset): New function, which is like ASET but can be
252 used in the garbage collector.

266 (map_w32_filename): Improve commentary. Simplify switch.
267 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
268 headers (most versions of MinGW w32api don't).
269 (get_security_info, create_symbolic_link)
270 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
272 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
273 in the argument file name.

275 GetFileAttributes fails with network-related error codes.
276 (sys_rename): Diagnose renaming of a symlink when the user doesn't
277 have the required privileges.
278 (get_file_security_desc_by_name): Renamed from
279 get_file_security_desc.
280 (stat_worker): New function, with most of the guts of 'stat', and
281 with addition of handling of symlinks and support for 'lstat'. If
282 possible, get file's attributes and security information by
283 handle, not by name. Produce S_IFLNK bit for symlinks, when
285 (stat, lstat): New functions, call 'stat_worker'.
286 (symlink, readlink, careadlinkat): Rewritten to create and resolve
287 symlinks when the underlying filesystem supports them.
289 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
291 Fix macroexp crash on Windows with debugging (Bug#12118).
292 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
293 checking subscripts; problem introduced with the recent
294 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
295 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
296 since it's used in non-static inline functions now.
298 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
299 Don't assume buffer size fits in 'int'. Remove unused local.
301 Use C99-style 'extern inline' if available.
302 * buffer.h (BUFFER_INLINE):
303 * category.h (CATEGORY_INLINE):

319 * composite.c (COMPOSITE_INLINE):
320 * dispnew.c (DISPEXTERN_INLINE):
321 * sysdep.c (SYSTIME_INLINE):
322 Define to EXTERN_INLINE, so that the corresponding functions
323 are compiled into code.
324 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
325 (INLINE_HEADER_END): New macros.
326 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

348 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
350 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
351 This how ASET and AREF are supposed to work, and makes
352 it easier to think about future improvements. See
353 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
354 * charset.h (set_charset_attr): New function.

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

859 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
860 not be usable in #if. This simplifies things.
862 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
864 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
866 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

871 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
872 Adjust to changes in lisp.h and emacs.c, by using

885 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

888 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
889 (gdb_USE_LSB_TAG): New enum constants.
890 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

893 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
894 as constants, so they're visible to GDB.
895 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

897 Now enum constants, not macros, so they're visible to GDB.
898 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
899 more convenient now. All uses changed.
900 (VALMASK) [USE_LSB_TAG]: Also define in this case.

1782 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1783 Prefer snprintf to strncpy.
1784 * nsterm.m (ns_term_init):
1785 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1786 * nsterm.m (ns_term_init):
1787 Avoid the need for strncpy, by using build_string or
1788 make_unibyte_string directly. Use dtoastr, not snprintf.
1789 * process.c (Fmake_network_process): Diagnose service names that
1790 are too long, rather than silently truncating them or creating

1808 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1809 where argument type is known to be a Lisp_Cons.

1824 provides a better opportunity to optimize away calls to strlen when
1825 the function is called with compile-time constant argument.
1826 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1827 argument, adjust users accordingly. Use build_pure_c_string where
1829 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1830 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1831 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1833 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1835 Avoid calls to strlen in miscellaneous functions.
1836 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1837 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1838 * lread.c (openp): Likewise.
1840 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1842 Avoid calls to strlen in path processing functions.
1843 * fileio.c (file_name_as_directory): Add comment. Change to add
1844 srclen argument and return the length of result. Adjust users
1846 (directory_file_name): Fix comment. Change to add srclen argument,
1847 swap 1st and 2nd arguments to obey the common convention. Adjust
1849 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1851 2012-07-10 Glenn Morris <rgm@gnu.org>

1858 * s/gnu.h (DATA_START): Move definitions to configure.
1860 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1861 We include usg5-4-common.h, which defines them both.
1863 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1864 O_RDONLY already includes it).
1866 Stop ns builds setting the EMACSLOADPATH environment variable.
1867 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1868 Now it does not set EMACSLOADPATH, just returns the load-path string.
1869 * nsterm.h: Update accordingly.
1870 * lread.c [HAVE_NS]: Include nsterm.h.
1871 (init_lread) [HAVE_NS]: Use ns_load_path.

1874 2012-07-09 Glenn Morris <rgm@gnu.org>
1876 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1877 since the included bsd-common.h does so.
1879 Stop ns builds setting the EMACSPATH environment variable.
1880 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1881 (ns_init_paths): Do not set EMACSPATH.
1882 * nsterm.h (ns_exec_path): Add it.
1883 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1886 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1888 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1890 * process.c (wait_reading_process_output): 'waitchannels' was unset
1891 when read_kbd || !NILP (wait_for_cell); fix this.
1893 Add GCC-style 'const' attribute to functions that can use it.
1894 * character.h (char_resolve_modifier_mask):
1895 * keyboard.h (make_ctrl_char):
1896 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1903 Declare the dummy function with ATTRIBUTE_CONST.
1904 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1905 Add decls with ATTRIBUTE_CONST.
1907 Minor improvements to make_formatted_string.
1908 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1909 where int is good enough, as vsprintf returns an int.
1910 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1912 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1914 Use make_formatted_string to avoid double length calculation.
1915 * lisp.h (make_formatted_string): New prototype.
1916 * alloc.c (make_formatted_string): New function.
1917 * buffer.c (Fgenerate_new_buffer_name): Use it.

1921 * frame.c (make_terminal_frame, set_term_frame_name)
1922 (x_report_frame_params): Likewise.
1923 * image.c (gs_load): Likewise.

1937 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1939 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1941 Move marker debugging code under MARKER_DEBUG.
1942 * marker.c (MARKER_DEBUG): Move marker debugging code under
1943 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1944 for bootstrap with --enable-checking (~3x slowdown reported
1945 by Juanma Barranquero <lekktu@gmail.com>).
1946 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1948 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1950 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1951 See <http://bugs.gnu.org/11825#29>.
1953 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1955 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1956 has no font, use the frame's font. (Bug#11813)
1957 (display_line): Add commentary about displaying truncation glyphs
1959 (produce_special_glyphs): Move here from term.c.
1961 * term.c (produce_special_glyphs): Move to xdisp.c.
1963 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1966 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1968 * xdisp.c (display_line): Avoid warning about implicit declaration
1971 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1973 * lisp.h: Remove empty conditional.
1975 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1977 * lread.c (load_path_check): Now static.
1979 Fix some minor --with-ns problems found by static checking.
1980 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1981 (x_set_font) [!HAVE_X_WINDOWS]:
1982 * image.c (xpm_load_image) [HAVE_NS]:
1983 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1984 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1985 Remove unused local.
1986 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1987 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1988 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1989 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1990 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1991 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1992 Fix pointer signedness problem.
1993 * xfaces.c (FRAME_X_FONT_TABLE):
1994 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1996 2012-07-07 Glenn Morris <rgm@gnu.org>
1998 * lread.c (load_path_check): New function, split from init_lread.
1999 (init_lread): Reorganize. Motivation:
2000 If EMACSLOADPATH is set, check/warn about that rather than the
2001 defaults, which we are not going to use. Hence we can remove
2002 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2003 Don't warn if site-lisp directories are missing.
2004 If not installed, start from a blank load-path, since
2005 PATH_LOADSEARCH refers to the eventual installation directories.
2007 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2009 Support truncation and continuation glyphs on GUI frames, when
2010 fringes are disabled. (Bug#11832)
2011 * xdisp.c (init_iterator): Get dimensions of truncation and
2012 continuation glyphs even if on GUI frames. Adjust
2013 it->last_visible_x on GUI frames when the left or right fringes,
2014 or both, are absent.
2015 (start_display, move_it_in_display_line_to): Handle the case of a
2016 GUI frame without a fringe to display continuation or truncation
2018 (insert_left_trunc_glyphs): Support GUI frames: make sure
2019 truncation glyphs overwrite enough glyphs from the current line to
2020 have sufficient space in pixels.
2021 (display_line): Support truncation and continuation glyphs on GUI
2022 frames. If some spare pixels are left on the line after inserting
2023 the truncation glyphs, fill that space with a stretch glyph of a
2024 suitably computed width.
2026 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2027 produce_glyphs, to support GUI sessions.
2029 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2031 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2033 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2035 Do not require float-time's arg to fit in time_t (Bug#11825).
2036 This works better on hosts where time_t is unsigned, and where
2037 float-time is applied to the (negative) difference between two times.
2038 * editfns.c (decode_time_components): Last arg is now double *,
2039 not int *, and means to store all the result as a double, without
2040 worrying about whether the seconds part fits in time_t.
2041 All callers changed.
2042 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2043 All callers changed.
2044 (Ffloat_time): Do not fail merely because the specified time falls
2045 outside of time_t range.
2047 2012-07-07 Glenn Morris <rgm@gnu.org>
2049 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2055 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2056 Update dependencies.
2058 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2060 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2062 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

2064 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2065 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2066 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2067 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2069 * xfont.c (compare_font_names): Redo to omit the need for casts.
2071 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2073 * xfns.c (Fx_change_window_property): Doc fix.
2074 * w32fns.c (Fx_change_window_property): Doc fix.
2076 * w32fns.c (Fx_window_property): Accept the same arguments as the
2077 X Windows version. Doc fix.
2078 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2080 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2081 Eli Zaretskii <eliz@gnu.org>
2083 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2084 Windows-specific code from nt/config.nt moved here.
2085 Obsolete settings removed.
2087 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2089 * process.c: Avoid unnecessary calls to gettime.
2090 (wait_reading_process_output): Don't get the time of day
2091 when gobbling data immediately and not waiting, as there's no need
2092 for it in that case. This removes a FIXME.
2094 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2096 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2097 is defined (Bug#11768).

2102 * marker.c (byte_char_debug_check): Do not perform the check
2103 if buffer is not multibyte.
2104 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2105 Call byte_char_debug_check with correct arguments.
2107 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2109 Compile marker debugging code only if ENABLE_CHECKING is defined.
2110 * marker.c (byte_char_debug_check, count_markers):
2111 Use only if ENABLE_CHECKING is defined.
2112 (byte_debug_flag): Remove.
2113 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2114 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2116 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2118 Avoid code repetition in marker-related functions.
2119 * marker.c (attach_marker): New function.
2120 (Fset_marker, set_marker_restricted, set_marker_both)
2121 (set_marker_restricted_both): Use it.
2122 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2123 Consistently rename charno to charpos.
2124 (marker_position): Add eassert.
2125 (marker_byte_position): Convert to eassert.

2144 * window.c (save_window_save): Likewise.
2146 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2148 Do not use Fdelete_overlay in delete_all_overlays
2149 to avoid redundant calls to unchain_overlay.
2150 * buffer.c (drop_overlay): New function.
2151 (delete_all_overlays, Fdelete_overlay): Use it.
2152 * minibuf.c (get_minibuffer): Fix comment.

2156 Port to OpenBSD 5.1 amd64.
2157 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2158 This is needed for OpenBSD, and should be harmless on all BSD systems.
2159 Also, include <sys/sysctl.h>, as it should be available on all
2160 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2161 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2162 use p_pid member, not kp_proc.pid.
2164 2012-07-06 Glenn Morris <rgm@gnu.org>
2166 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

2179 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2181 Omit needless casts involving void * pointers and allocation.
2182 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2183 as the former is more robust if P's type is changed.
2184 Prefer xzalloc to xmalloc + memset 0.
2185 Simplify malloc-or-realloc to realloc.
2186 Don't worry about xmalloc returning a null pointer.
2187 Prefer xstrdup to xmalloc + strcpy.
2188 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2190 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2191 alloca of a constant.
2193 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2195 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2196 hscroll is larger than the line width. Fixes long and futile
2197 looping inside extend_face_to_end_of_line (on a TTY) producing
2198 glyphs that are not needed and thrown away.
2200 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2202 * marker.c (set_marker_restricted_both): Simplify by using

2228 * xdisp.c (window_hscroll_limited): New function.
2229 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2230 coordinates when window's hscroll is set to insanely large
2233 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2235 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2296 * fileio.c (time_error_value): Check the right error number.
2297 Problem reported by Troels Nielsen in
2298 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2300 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2302 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2303 This should be fixed in a better way; see Eli Zaretskii in
2304 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2305 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2307 * fileio.c (time_error_value): Rename from special_mtime.
2308 The old name's problems were noted by Eli Zaretskii in
2309 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2311 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2312 This variable's comment says Emacs needs at least one GDB-visible
2313 symbol of type enum pvec_type, to work around GDB problems.
2314 The symbol's value doesn't matter.
2316 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2317 that causes compilation to fail on pre-C99 compilers.
2319 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2321 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2322 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2324 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2326 * buffer.c (init_buffer_once): Fix initialization of
2327 headers for buffer_defaults and buffer_local_symbols.
2328 Reported by Juanma Barranquero <lekktu@gmail.com>.
2330 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2332 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2333 * lisp.h (enum pvec_type): Use fewer bits.
2334 (PSEUDOVECTOR_SIZE_BITS): New constant.
2335 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2336 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2337 change in pvec_type.
2338 (PSEUDOVECTOR_TYPEP): New macro.
2339 (TYPED_PSEUDOVECTORP): Use it.
2340 * fns.c (internal_equal): Adapt code to extract pvectype.
2341 * emacs.c (gdb_pvec_type): Update type.
2342 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2343 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2344 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2345 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2346 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2347 abusing vector->header.next.nbytes.
2348 (live_vector_p): Use PVEC_TYPE.
2349 (mark_object): Adapt code to extract pvectype. Use switch.
2351 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2353 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2354 Tighten new eassert a bit.
2356 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2358 Fix compilation with --enable-gcc-warnings and -O1
2360 * doprnt.c (doprnt): Change type of tem to int, initialize
2361 to avoid compiler warning. Add eassert.
2362 * search.c (simple_search): Initialize match_byte to avoid
2363 compiler warning. Add eassert.
2365 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2367 Avoid weird behavior with large horizontal scrolls.
2368 Without this change, for example, large hscroll values would
2369 mess up Emacs's display on Fedora 15 x86, presumably due to
2370 overflows in int calculations in the display code.
2371 Also, if buffers had long lines, Emacs would freeze.
2372 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2373 (set_window_hscroll): New function, containing the old guts of
2374 Fset_window_hscroll. Return the clipped value.
2375 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2376 This avoids the need to check against PTRDIFF_MAX.
2378 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2380 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2382 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2384 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2386 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2387 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2388 since GCC 4.4.6 issues a bogus warning for them.
2390 Fix bugs in file timestamp newness comparisons.
2391 * fileio.c (Ffile_newer_than_file_p):
2392 * lread.c (Fload): Use full timestamp resolution of files,
2393 not just the 1-second resolution, so that files that are only
2394 slightly newer still count as newer.
2395 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2396 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2398 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2400 * fileio.c: Improve handling of file time marker. (Bug#11852)
2401 (special_mtime): New function.
2402 (Finsert_file_contents, Fverify_visited_file_modtime):
2403 Use it to set special mtime values consistently.
2405 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2407 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2408 marker for non-existing file. (Bug#11852)
2410 2012-07-03 Glenn Morris <rgm@gnu.org>
2412 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2413 and did not make it into globals.h).
2415 2012-07-03 Tom Tromey <tromey@redhat.com>
2417 * window.c (Fset_window_margins, Fset_window_fringes)
2418 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2419 * textprop.c (Fprevious_property_change): No longer static.
2420 * syntax.c (Fsyntax_table_p): No longer static.

2442 * intervals.h: Remove EXFUNs.
2443 * fontset.h: Remove EXFUN.

2448 * w32term.h: Remove EXFUNs.
2449 * window.h: Remove EXFUNs.
2450 * xsettings.h: Remove EXFUN.
2451 * xterm.h: Remove EXFUN.
2453 2012-07-03 Glenn Morris <rgm@gnu.org>
2455 * lisp.h (Frandom): Make it visible to C.
2456 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2457 buffer for invisible buffers. (Bug#1229)
2459 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2461 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2462 values which aren't power of 2.
2463 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2464 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2467 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2469 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2471 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2473 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2475 * alloc.c (allocate_vector_block): Remove redundant
2476 calls to mallopt if DOUG_LEA_MALLOC is defined.
2477 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2478 avoid calls to mallopt if zero_vector is returned.
2480 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2482 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2483 is enabled, avoid dereferencing NULL current_sblock if
2486 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2488 Cleanup basic buffer management.
2489 * buffer.h (struct buffer): Change layout to use generic vector
2490 marking code. Fix some comments. Change type of 'clip_changed'
2491 to bitfield. Remove unused #ifndef old.
2492 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2493 (GET_OVERLAYS_AT): Fix indentation.
2494 (for_each_per_buffer_object_at): New macro.
2495 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2496 (Fbuffer_local_variables): Use it.
2497 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2498 * alloc.c (allocate_buffer): Adjust to match new layout of
2499 struct buffer. Fix comment.
2500 (mark_overlay): New function.
2501 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2502 Lisp area of struct buffer.
2503 (mark_object): Use it. Adjust marking of misc objects
2504 and related comments.
2506 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2508 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2509 wrapper that is not needed because the wrapped code is a no-op (zero
2510 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2511 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2513 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2515 * alloc.c (mark_buffer): Simplify. Remove prototype.
2516 (mark_object): Add comment. Reorganize marking of vector-like
2517 objects. Use CHECK_LIVE for all vector-like objects except buffers
2518 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2519 redundant calls to mark_vectorlike for bool vectors.
2521 2012-06-30 Glenn Morris <rgm@gnu.org>
2523 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2525 * epaths.in (PATH_SITELOADSEARCH): New.
2526 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2527 This is rather than relying on --enable-locallisppath elements
2528 having "site-lisp" in their names. (Bug#10208#25, 11658)
2530 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2532 * w32proc.c (sys_select): Accept and ignore one more argument.
2534 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2536 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2537 (pselect) [!MS_DOS]: Redirect to sys_select.
2539 * sysdep.c: Don't include dos.h and dosfns.h.
2541 * process.c (sys_select):
2542 * msdos.c (sys_select): Accept one more argument and ignore it.
2544 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2545 adapt data types and code to that.
2548 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2549 which clashes with the gnulib function of the same name.
2551 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2553 * font.c (font_style_to_value, font_style_symbolic)
2554 (font_prop_validate_style): Add type checks for values in
2557 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2559 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2562 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2564 * xdisp.c (try_window_id): Undo last change.
2566 * w32.c (getwd): Adjust commentary about startup_dir.
2567 (init_environment): Always call sys_access, even in non-MSVC
2568 builds. Don't chdir to the directory of the Emacs executable.
2569 This undoes code from 1997 which was justified by the need to
2570 "avoid conflicts when removing and renaming directories". But its
2571 downside was that every relative file name was being interpreted
2572 relative to the directory of the Emacs executable, which can never
2573 be TRT. In particular, it broke sys_access when called with
2574 relative file names.
2575 (sys_access): Map GetLastError to errno.
2577 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2579 * window.h (struct window): Change type of 'fringes_outside_margins'
2580 to bitfield. Fix comment. Adjust users accordingly.
2581 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2583 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2586 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2588 * gnutls.c (emacs_gnutls_handshake):
2589 Add QUIT to make the loop interruptible.
2591 2012-06-29 Glenn Morris <rgm@gnu.org>
2593 * charset.c (init_charset): Make lack of etc/charsets fatal.
2595 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2597 * editfns.c (region_limit): Fix type mismatch.
2599 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2601 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2602 undefined. Convert from xassert to eassert.
2603 * nsmenu.m: Convert from xassert to eassert.
2604 * nsterm.m: Likewise.
2606 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2608 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2610 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2612 Avoid integer overflow on scroll-left and scroll-right.
2613 * window.c (HSCROLL_MAX): New macro.
2614 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2615 overflow when requested scroll falls outside ptrdiff_t range.
2617 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2619 * window.h (struct window): Change type of 'hscroll',
2620 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2621 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2622 Adjust users accordingly.
2623 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2624 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2625 from EMACS_INT to ptrdiff_t.
2626 (make_window): Omit redundant initialization.
2628 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2630 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2632 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2634 * window.h (struct window): Change type of 'use_time' and
2635 'sequence_number' from Lisp_Object to int.

2645 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2646 adjust comments accordingly.

2695 * alloc.c (allocate_string_data): Remove dead code.
2696 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2697 avoid GCC warning about unused macro.
2699 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2701 * alloc.c (allocate_string): Omit intervals initialization.
2702 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2703 as in make_pure_string and make_pure_c_string.
2705 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2707 * alloc.c (allocate_string): Fix last change.
2709 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2742 * alloc.c (allocate_window): Zero out non-Lisp part of newly

2759 * alloc.c: Remove build_string.
2760 * lisp.h: Define build_string as static inline. This provides
2761 a better opportunity to optimize away calls to strlen when the
2762 function is called with compile-time constant argument.
2763 * image.c (imagemagick_error): Convert to build_string.
2764 * w32proc.c (sys_spawnve): Likewise.
2765 * xterm.c (x_term_init): Likewise.
2767 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2769 Use sprintf return value instead of invoking strlen on result.
2770 In the old days this wasn't portable, since some sprintf
2771 implementations returned char *. But they died out years ago and
2772 Emacs already assumes sprintf returns int.
2773 Similarly for float_to_string.
2774 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2785 * lisp.h, print.c (float_to_string): Now returns int length.
2786 * term.c (produce_glyphless_glyph):
2787 Use sprintf result rather than recomputing it.

2888 * keyboard.c (kbd_buffer_get_event):
2889 * process.c (Faccept_process_output):
2890 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2891 This improves on the previous patch, which introduced a bug
2892 when time_t is unsigned and as wide as intmax_t.
2893 See <http://bugs.gnu.org/9000#51>.
2895 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2897 * dispnew.c (sit_for, Fsleep_for):

2916 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2918 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2920 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in

2924 language ID in the event parameters.
2926 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2958 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2960 Support higher-resolution time stamps (Bug#9000).
2961 The time stamps are only nanosecond-resolution at the C level,
2962 since that's the best that any real-world system supports now.
2963 But they are picosecond-resolution at the Lisp level, as that's
2964 easy, and leaves room for future OS improvements.
2966 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2969 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2970 Don't get current time unless it's needed.
2972 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2973 now provides it if it's absent.
2974 (start_atimer): Port to higher-res time stamps.
2975 Check for time stamp overflow. Don't get current time more
2976 often than is needed.
2978 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2979 Include systime.h, not time.h.
2980 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2982 * dired.c: Include stat-time.h.
2983 (Ffile-attributes): File times now have higher resolution.

2986 (struct image): Timestamp now has higher resolution.
2988 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2989 has at least microseconds now. All uses removed.
2990 (update_frame, update_single_window, update_window, update_frame_1)
2991 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2993 * editfns.c (time_overflow): Now extern.
2994 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2995 (float-time, Fformat_time_string, Fcurrent_time_string)
2996 (Fcurrent_time_zone): Accept and generate higher-resolution
2998 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2999 (decode_time_components, lisp_seconds_argument): New functions.
3000 (make_time): Now static.
3001 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3002 Report an error if the time is invalid, rather than having the caller
3005 * fileio.c: Include <stat-time.h>
3006 (Fcopy_file): Copy higher-resolution time stamps.
3007 Prefer to set the time stamp via a file descriptor if that works.
3008 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3009 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3010 (Fvisited_file_modtime, Fset_visited_file_modtime):
3011 Support higher-resolution time stamps.
3013 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3015 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3017 * image.c (prepare_image_for_display, clear_image_cache)
3018 (lookup_image): Port to higer-resolution time stamps.
3020 * keyboard.c (start_polling, bind_polling_period):
3021 Check for time stamp overflow.
3022 (read_char, kbd_buffer_get_event, timer_start_idle)
3023 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3024 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3025 Port to higher-resolution time stamps. Do not assume time_t is signed.
3026 (decode_timer): New function. Timers are now vectors of length 9,
3027 not 8, to accommodate the picosecond component.
3028 (timer_check_2): Use it.
3030 * nsterm.m (select_timeout, timeval_subtract): Remove.
3031 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3032 as they're a bit more accurate and handle overflow better.
3033 (ns_select): Change prototype to be compatible with pselect.
3034 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3035 * nsterm.h (ns_select): Adjust prototype.
3037 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3038 us-resolution time stamps.
3039 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3041 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3043 * lisp.h (time_overflow): New decl.
3044 (wait_reading_process_output): First arg is now intmax_t, not int,
3045 to accommodate larger waits.
3047 * process.h (struct Lisp_Process.read_output_delay):
3048 Now counts nanoseconds, not microseconds.
3049 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3051 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3052 (wait_reading_process_output):
3053 Port to ns-resolution time stamps.
3054 (Faccept_process_output, wait_reading_process_output):
3055 Check for time stamp overflow. Do not assume time_t is signed.
3056 (select_wrapper): Remove; we now use pselect.
3057 (Fprocess_attributes): Now generates ns-resolution time stamps.
3059 * sysdep.c: Include utimens.h. Don't include utime.h
3060 or worry about struct utimbuf; gnulib does that for us now.
3061 (gettimeofday): Remove; gnulib provides a substitute.
3062 (make_timeval): New function.
3063 (set_file_times): Now sets ns-resolution time stamps.
3064 New arg FD; all uses changed.
3065 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3066 (system_process_attributes):
3067 Now returns ns-resolution time stamp. All uses changed.
3068 Check for time stamp overflow.
3070 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3071 provides a substitute now.
3073 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3074 since it guarantees struct timespec.
3075 (EMACS_TIME): Now struct timespec, so that we can support
3076 ns-resolution time stamps.
3077 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3078 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3079 (EMACS_USECS): Remove.
3080 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3081 so multiply the arg by 1000 before storing it.
3082 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3084 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3085 Port to ns-resolution time stamps.
3086 (EMACS_TIME_NEG_P): Remove; replaced by....
3087 (EMACS_TIME_SIGN): New macro.
3088 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3089 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3090 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3091 (make_timeval, make_lisp_time, decode_time_components): New decls.
3092 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3093 that it mishandled time_t overflow. You can't compare by subtracting!
3094 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3095 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3097 * term.c: Include <sys/time.h>.
3098 (timeval_to_Time): New function, for proper overflow wraparound.

3103 (Fprimitive_undo): Use them when restoring time stamps.
3105 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3106 (w32_get_internal_run_time):
3107 Port to higher-resolution Emacs time stamps.
3108 (ltime): Now accepts single 64-bit integer, as that's more convenient
3111 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3113 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3114 for compatibility with pselect. Support ns-resolution time stamps.
3116 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3118 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3119 Check for time stamp overflow, and support ns-resolution time stamps.
3121 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3122 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3123 (timeval_subtract): Remove; no longer needed.
3124 (XTflash, XTring_bell, x_wait_for_event):
3125 Port to ns-resolution time stamps. Don't assume time_t is signed.
3127 2012-06-22 Chong Yidong <cyd@gnu.org>

3131 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3133 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3134 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3135 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3136 staticidx goes up to 1597 out of 1600 = 0x640.)
3138 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3140 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3141 Otherwise, the umask might be mistakenly 0 while handling input signals.
3143 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3145 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3151 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3152 access to `contents' member of Lisp_Vector objects with AREF and ASET
3155 2012-06-19 Chong Yidong <cyd@gnu.org>
3157 * frame.c (delete_frame): When selecting a frame on a different
3158 text terminal, do not alter the terminal's top-frame.

3162 (unwind_format_mode_line): Restore them.
3163 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3165 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3166 since tty frames can be explicitly named.
3167 (prepare_menu_bars): Likewise.
3169 * term.c (Ftty_top_frame): New function.
3171 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3173 Port byte-code-meter to modern targets.
3174 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3175 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3176 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3177 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3178 (METER_1, METER_2): Simplify.
3180 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3182 * data.c (Fdefalias): Return `symbol' (bug#11686).
3184 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3186 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3187 gets killed during executing of this function (Bug#11665).
3188 Try to always return Qt when the buffer has been actually killed.
3189 (Vkill_buffer_query_functions): In doc-string say that functions
3190 run by this hook should not change the current buffer.
3192 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3194 Fix recently-introduced process.c problems found by static checking.
3195 * process.c (write_queue_push, write_queue_pop, send_process):

3197 (write_queue_pop): Fix pointer signedness problem.
3198 (send_process): Remove unused local.
3200 2012-06-17 Chong Yidong <cyd@gnu.org>

3203 frames that are not on top.
3205 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
3207 * process.c (make_process): Initialize write_queue.
3208 (write_queue_push, write_queue_pop): New functions.
3209 (send_process): Use them to maintain correct ordering of process
3212 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3214 * lisp.h (eassert): Assume C89 or later.
3215 This removes the need for CHECK.
3216 (CHECK): Remove. Its comments about always evaluating its
3217 argument were confusing, as 'eassert' typically does not evaluate
3220 * coding.c (produce_chars): Use ptrdiff_t, not int.
3222 * xterm.c (x_draw_underwave): Check for integer overflow.
3223 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
3225 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
3227 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

3408 code works fine either way, and efficiency is not a concern here,
3409 as the union type is for debugging, not for production.
3410 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3411 Use an inline function on all platforms when using the union type,
3412 since this is simpler and 'static inline' can be used portably

3556 * doprnt.c (doprnt): Truncate multibyte char correctly.
3557 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3558 would mishandle a string argument "Xc" if X was a multibyte

3613 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3614 Convert pctcpu and pctmem to Lisp float properly.

3619 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

3634 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3635 fields from Lisp_Object to bitfield. Adjust users accordingly.

3643 and 'double' in a couple of places.
3645 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3647 * xdisp.c (handle_stop): Detect whether we have overlay strings
3648 loaded by testing it->current.overlay_string_index to be
3649 non-negative, instead of checking whether n_overlay_strings is
3650 positive. (Bug#11587)
3652 2012-05-31 Chong Yidong <cyd@gnu.org>

3660 * search.c (search_buffer): Remove calls to
3661 r_alloc_inhibit_buffer_relocation, as it is now called by
3662 maybe_unify_char, which was the cause of relocation of buffer text
3665 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3667 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3668 for the duration of call to load_charset, to avoid problems with
3669 callers of maybe_unify_char that access buffer text through C
3672 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3673 decrement the inhibition flag, instead of just setting or
3676 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>

3679 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

3683 (gray_bitmap_bits): Remove; no longer needed.

3725 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3727 Do not create empty overlays with the evaporate property (Bug#9642).
3728 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3729 Bug#9642, but explicitly check that the buffer the overlay would
3730 be moved to is live and rearrange lines to make sure that errors
3731 will not put the overlay in an inconsistent state.
3732 (Fdelete_overlay): Cosmetics.
3734 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3736 * w32term.c (my_bring_window_to_top): New function.
3737 (x_raise_frame): Use handle returned by DeferWindowPos, which
3738 could be different from the original one.

3742 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3743 by calling BringWindowToTop.
3745 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3746 (WM_EMACS_END): Increase by one.
3748 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3750 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3751 This avoids undefined behavior that might cause the eassert
3752 to not catch an out-of-range value.
3754 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3756 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3757 Update dependencies.
3759 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3761 * bidi.c (bidi_mirror_char): Fix last change.
3763 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

3766 when referring to sectname field in printf format.
3768 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3770 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3771 Only r_alloc_inhibit_buffer_relocation needed to be added;
3772 the others were already declared.
3774 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3775 before checking whether it's out of range. Put the check inside
3777 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3779 2012-05-27 Ken Brown <kbrown@cornell.edu>
3781 * callproc.c (Fcall_process): Restore a line that was accidentally
3782 commented out in the 2011-02-13 change (bug#11547).
3784 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3786 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3787 defined on ralloc.c.
3789 * buffer.c [REL_ALLOC]: Remove prototypes of
3790 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3791 they are now on lisp.h.
3793 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3795 * search.c (search_buffer): Use it to inhibit relocation of buffer
3796 text while re_search_2 is doing its job, because re_search_2 is
3797 passed C pointers to buffer text. (Bug#11519)
3799 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3802 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3803 state after an additional call to move_it_in_display_line_to, keep
3804 the values of it->max_ascent and it->max_descent found for the
3806 (pos_visible_p): Revert the comparison against bottom_y to what it
3807 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3810 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3812 Fix coding-related core dumps with gcc -ftrapv.
3813 The code was computing A - B, where A and B are pointers, and B is
3814 random garbage. This can lead to core dumps on platforms that
3815 have special pointer registers, and it also leads to core dumps on
3816 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3817 A - B only when B is initialized properly.
3818 * coding.c (coding_set_source, coding_set_destination): Return void.
3819 (coding_change_source, coding_change_destinations): New functions,
3820 with the old behaviors of coding_set_source and coding_set_destination.
3821 All callers that need an offset changed to use these new functions.
3823 2012-05-26 Glenn Morris <rgm@gnu.org>
3825 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3827 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3829 Extend mouse support on W32 text-mode console.
3830 * xdisp.c (draw_row_with_mouse_face):
3831 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3833 * w32console.c: Include window.h.
3834 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3836 (initialize_w32_display): Initialize mouse-highlight data.
3838 * w32inevt.c: Include termchar.h and window.h.
3839 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3840 moves, call note_mouse_highlight. If help_echo changed, call
3841 gen_help_event to produce help-echo message in the echo area.
3842 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3845 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3847 * lread.c (read1): Simplify slightly to avoid an overflow warning
3848 with GCC 4.7.0 on x86-64.
3850 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3852 * bidi.c (bidi_mirror_char): Revert last change: an int is
3853 definitely wide enough here.
3855 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3857 Fix integer width and related bugs (Bug#9874).

3865 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3867 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3868 (allocate_pseudovector):
3869 Use int, not EMACS_INT, where int is wide enough.
3870 (inhibit_garbage_collection, Fgarbage_collect):
3871 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3872 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3873 int might not be wide enough.
3874 (bidi_cache_search, bidi_cache_find, bidi_init_it)

3878 (bidi_level_of_next_char, bidi_move_to_visually_next):
3879 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3880 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3881 (Fkill_buffer, Fset_buffer_major_mode)

3888 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3889 (Foverlay_recenter, last_overlay_modification_hooks_used)
3890 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3891 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3892 (validate_region): Omit unnecessary test for b <= e,
3893 since that's guaranteed by the previous test.
3894 (adjust_overlays_for_delete): Avoid pos + length overflow.
3895 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3896 (report_overlay_modification):
3897 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3898 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3899 Omit pointer cast, which isn't needed anyway, and doesn't work
3900 after the EMACS_INT -> ptrdiff_t change.

3902 * buffer.h: Adjust decls to match defn changes elsewhere.

3907 not int, to avoid needless 32-bit limit on 64-bit hosts.
3908 (exec_byte_code): Use tighter memory-full test, one that checks
3909 for alloca overflow. Don't compute the address of the object just
3910 before an array, as that's not portable. Use EMACS_INT, not
3911 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3912 * callint.c (Fcall_interactively):
3913 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3924 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3925 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3926 (casify_object): Avoid integer overflow when overallocating buffer.
3927 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3928 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3929 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3930 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3931 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3932 integers are now checked earlier. All uses replaced with XINT.
3934 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3935 For CCL_MapSingle, check that content and value are in int range.
3936 (ccl_driver, Fregister_code_conversion_map):
3937 Check that Vcode_version_map_vector is a vector.
3938 (resolve_symbol_ccl_program): Check that vector header is in range.
3939 Always copy the vector, so that we can check its contents reliably
3940 now rather than having to recheck each instruction as it's being
3941 executed. Check that vector words fit in 'int'.
3942 (ccl_get_compiled_code, Fregister_ccl_program)
3943 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3944 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3945 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3946 contents are in range.
3947 (Fccl_execute_on_string): Check that status is in range.
3948 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3949 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3950 Accept and return EMACS_INT, not int, because callers can pass values
3952 (c_string_width, strwidth, lisp_string_width, chars_in_text)

3955 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3956 (string_escape_byte8, Fget_byte):
3957 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3958 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3959 avoid mishandling large integers.
3960 * character.h: Adjust decls to match defn changes elsewhere.

3969 (Fdefine_charset_internal): Check ranges here, more carefully.
3970 Don't rely on undefined behavior with signed left shift overflow.
3971 Don't assume unsigned int fits into fixnum, or that fixnum fits
3972 into unsigned int. Don't require max_code to be a valid fixnum;
3973 that's not true for gb10830 4-byte on a 32-bit host. Allow
3974 invalid_code to be a cons, for the same reason. Require code_offset
3975 to be a character. Avoid int overflow if max_char is close
3977 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3978 this is intended anyway and avoids some undefined behavior.
3979 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3980 INDEX_TO_CODE_POINT, as that's what it expects.
3981 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3982 * charset.h (DECODE_CHAR): Return int, not unsigned;
3983 this is what was intended anyway, and it avoids undefined behavior.
3984 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3985 integer-overflow issues.
3986 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3987 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3988 where the argument is EMACS_INT, and this behavior is not intended.
3989 * chartab.c (Fmake_char_table, Fset_char_table_range)
3990 (uniprop_get_decoder, uniprop_get_encoder):
3991 Don't assume fixnum fits in int.
3992 * cmds.c (move_point): New function, that does the gist of
3993 Fforward_char and Fbackward_char, but does so while checking
3994 for integer overflow more accurately.
3995 (Fforward_char, Fbackward_char): Use it.
3996 (Fforward_line, Fend_of_line, internal_self_insert)
3997 (internal_self_insert):
3998 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3999 Fix a FIXME, by checking for integer overflow when calculating
4000 target_clm and actual_clm.

4797 already have overlays loaded.
4798 (handle_single_display_spec): Before returning without displaying

4800 iterator, by calling iterate_out_of_display_property.

4802 testing that it->string is a Lisp string.
4803 (get_next_display_element): When the current object is exhausted,

4809 the display vector. (Bug#11417)
4810 (pos_visible_p): Don't report a position visible when move_it_to
4811 stopped at the last line of window, which happens to be scanned

4816 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4817 and right-margin display specs even if the spec is invalid or we
4818 are on a TTY, and thus unable to display on the fringes.
4819 That's because the text with the property will not be displayed anyway,
4820 so we need to signal to the caller that this is a "replacing"
4821 display spec. This fixes display when the spec is invalid or we
4824 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4826 * unexaix.c (make_hdr): Fix typo in prototype.

4859 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4861 * xgselect.c (xg_select): Put maxfds+1 into a var.
4862 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4864 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4866 2012-05-10 Dave Abrahams <dave@boostpro.com>
4868 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4869 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4871 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4873 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4874 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4875 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4876 Initialize xd_registered_buses.
4878 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4880 Untag more efficiently if USE_LSB_TAG.
4881 This is based on a proposal by YAMAMOTO Mitsuharu in
4882 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4883 For an admittedly artificial (nth 8000 longlist) benchmark on
4884 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4885 Emacs's overall text size by 1%.
4886 * lisp.h (XUNTAG): New macro.
4887 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4888 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4889 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4890 * eval.c (Fautoload):
4891 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4892 * frame.h (XFRAME): Use XUNTAG.
4894 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4895 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4896 Remove unportable assumptions about print widths of types like
4898 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4899 intptr_t when converting between pointer and integer, to avoid GCC
4900 warnings about wrong width.
4902 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4904 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4905 stack for each reader_thread, instead of defaulting to 8MB
4906 determined by the linker. This avoids failures in creating
4907 subprocesses on Windows 7, see the discussion in this thread:
4908 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4910 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4912 Fix up display of the *Minibuf-0* buffer in the mini window.
4913 * keyboard.c (read_char): Don't clear the echo area if there's no
4915 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4916 contents of *Minibuf-0*) if there's no message displayed in its stead.
4918 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4920 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4923 2012-05-06 Chong Yidong <cyd@gnu.org>
4925 * lisp.mk (lisp): Update.
4927 2012-05-05 Jim Meyering <meyering@redhat.com>
4929 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4931 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4933 * data.c (PUT_ERROR): New macro.
4934 (syms_of_data): Use it. Add new error type `user-error'.
4935 * undo.c (user_error): New function.
4936 (Fprimitive_undo): Use it.
4937 * print.c (print_error_message): Adjust print style for `user-error'.
4938 * keyboard.c (user_error): New function.
4939 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4941 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4943 Do not limit current-time-string to years 1000..9999.
4944 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4945 (Fcurrent_time_string): Support any year that is supported by the
4946 underlying localtime representation. Don't use asctime, as it
4947 has undefined behavior for years outside the range -999..9999.
4949 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4951 Fix race conditions involving setenv, gmtime, localtime, asctime.
4952 Without this fix, interrupts could mess up code that uses these
4953 nonreentrant functions, since setting TZ invalidates existing
4954 tm_zone or tzname values, and since most of these functions return
4955 pointers to static storage.
4956 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4957 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4958 Grow the critical sections to include not just invoking
4959 localtime/gmtime, but also accessing these functions' results
4960 including their tm_zone values if any, and any related TZ setting.
4961 (format_time_string): Last arg is now struct tm *, not struct tm **,
4962 so that the struct tm is saved in the critical section.
4963 All callers changed. Simplify allocation of initial buffer, partly
4964 motivated by the fact that memory allocation needs to be outside
4965 the critical section.
4967 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4969 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4970 with RESET_INTERVAL.
4972 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4973 Remove duplicated buffer name initialization.
4975 2012-05-02 Jim Meyering <jim@meyering.net>
4977 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4979 * xfns.c (x_window): Use xstrdup (Bug#11375).
4981 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4983 * xdisp.c (pos_visible_p): If already at a newline from the
4984 display string before the 'while' loop, don't walk back the glyphs
4985 from it3.glyph_row. Solves assertion violation when the display
4986 string begins with a newline (egg.el). (Bug#11367)
4988 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4990 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4993 2012-05-01 Glenn Morris <rgm@gnu.org>
4995 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4996 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4997 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4998 All were removed before 23.1.
5000 * dispnew.c: Remove HAVE_LIBNCURSES test;
5001 it is always true on relevant platforms.
5003 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5004 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5006 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5008 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5010 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5011 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5014 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5016 Do not avoid creating empty evaporating overlays (Bug#9642).
5017 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5018 That is, do not delete an evaporating overlay if it becomes
5019 empty after its bounds are adjusted to fit within its buffer.
5020 This fix caused other problems, and I'm reverting it until we get
5021 to the bottom of them.
5023 2012-04-27 Chong Yidong <cyd@gnu.org>
5025 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5027 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5029 * xdisp.c (pos_visible_p): If the window start position is beyond
5030 ZV, start the display from buffer beginning. Prevents assertion
5031 violation in init_iterator when the minibuffer window is scrolled
5034 * window.c (window_scroll_pixel_based): Likewise.
5036 2012-04-27 Chong Yidong <cyd@gnu.org>
5038 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5040 2012-04-27 Glenn Morris <rgm@gnu.org>
5042 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5043 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5045 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5047 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5048 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5050 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5052 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5053 display element, check also the underlying string or buffer
5054 character. (Bug#11341)
5056 * w32menu.c: Include w32heap.h.
5057 (add_menu_item): If the call to AppendMenuW (via
5058 unicode_append_menu) fails, disable Unicode menus only if we are
5059 running on Windows 9X/Me.
5061 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5063 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5064 (xgetint): Add missing shift for LSB tags.
5066 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5068 * keyboard.c (read_char): Don't wipe echo area for select window
5069 events: These might get delayed via `mouse-autoselect-window'
5072 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5074 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5075 manipulation of :loaded-from data.
5077 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5079 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5080 now a cons (bug#11311).
5082 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5084 Do not create empty overlays with the evaporate property (Bug#9642).
5085 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5086 if it becomes empty after its bounds are adjusted to fit within
5087 its buffer. Without this fix, in a nonempty buffer (let ((o
5088 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5089 yields an empty overlay that has the evaporate property, which is
5090 not supposed to happen.
5092 Fix minor GTK3 problems found by static checking.
5093 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5094 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5095 (struct _EmacsFixedClass, emacs_fixed_get_type):

5105 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5107 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5108 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5110 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5112 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5113 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5114 (__malloc_size_t, __malloc_ptrdiff_t):
5115 Remove. All uses removed, replaced by the definiens if needed,
5116 since we can assume C89 or better now.
5117 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5118 (protect_malloc_state, align, get_contiguous_space)
5119 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5125 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5126 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5127 Define using prototypes, not old style.
5128 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5129 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5130 (align): Don't assume that signed integer overflow wraps around.
5131 Omit unused local var.
5132 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5133 (_free_internal_nolock, memalign, mallochook, reallochook):

5192 * alloc.c: Handle unusual debugging option combinations.
5193 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5194 since the two debugging options are incompatible.

5207 * sysdep.c [__FreeBSD__]: Minor cleanups.
5208 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5209 Use Emacs indenting style more consistently. Avoid some casts.

5251 farther than the first row after the header line, if any.
5252 Don't consider the header-line row as "partially visible", even if
5253 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5255 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5308 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
5309 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5310 [REL_ALLOC]: ... to here, to check interface.
5311 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5312 Remove decls. This fixes an "It stinks!".
5314 * alloc.c (which_symbols): Fix alignment issue / type clash.
5316 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5318 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5319 (struct Lisp_Misc_Any): Likewise.
5320 (struct Lisp_Free): Likewise.
5321 * alloc.c (union aligned_Lisp_Symbol): Define.
5322 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
5323 aligned_Lisp_Symbol instead of struct Lisp_Symbol.
5324 (union aligned_Lisp_Misc): Define.
5325 (MARKER_BLOCK_SIZE, struct marker_block): Use union
5326 aligned_Lisp_Misc instead of union Lisp_Misc.
5327 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
5329 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5331 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5332 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5333 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5334 * s/netbsd.h, s/sol2-6.h:
5335 Remove definition of GC_MARK_STACK, since the default now works.
5336 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5337 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5338 no longer the default.
5339 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5341 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5343 * lread.c (lisp_file_lexically_bound_p):
5344 Fix hang at ";-*-\n" (bug#11238).

5351 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5353 * nsterm.m (constrainFrameRect): Always constrain when there is only
5354 one screen (Bug#10962).
5356 2012-04-13 Ken Brown <kbrown@cornell.edu>
5358 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

5364 2012-04-11 Daniel Colascione <dancol@dancol.org>
5366 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5367 against is gone. It's better to use vfork now so that when Cygwin
5368 gains a new, working vfork, we use it automatically (bug#10398).
5370 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5372 * window.c (save_window_save): Obey window-point-insertion-type.

5382 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5384 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5385 (force_quit_count): New var.
5386 (handle_interrupt): Use it.
5388 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5390 * w32.c (w32_delayed_load): Record the full path of the library
5391 being loaded (bug#10424).
5393 2012-04-09 Glenn Morris <rgm@gnu.org>
5395 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5396 not just in the obarray, before snarfing them. (Bug#11036)
5398 * Makefile.in ($(leimdir)/leim-list.el):
5399 Pass EMACS rather than BUILT_EMACS.
5401 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5403 * process.c (make_process):
5404 * process.h: Add integer `gnutls_handshakes_tried' member to
5407 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5408 Add convenience `GNUTLS_LOG2i' macro.
5410 * gnutls.c (gnutls_log_function2i): Convenience log function.
5411 (emacs_gnutls_read): Use new log functions,
5412 `gnutls_handshakes_tried' process member, and
5413 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5414 attempts per process (connection).
5416 2012-04-09 Chong Yidong <cyd@gnu.org>
5418 * eval.c (Fuser_variable_p, user_variable_p_eh)
5419 (lisp_indirect_variable): Functions deleted.
5420 (Fdefvar): Caller changed.
5422 * callint.c (Finteractive, Fcall_interactively):
5423 * minibuf.c (Fread_variable): Callers changed.
5425 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5427 * xdisp.c (set_cursor_from_row): If the display string appears in
5428 the buffer at position that is closer to point than the position
5429 after the display string, display the cursor on the first glyph of
5430 the display string. Fixes cursor display when a 'display' text
5431 property immediately follows invisible text. (Bug#11094)
5433 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5435 composite.c: use 'double' consistently
5436 * composite.c (get_composition_id): Use 'double' consistently
5437 instead of converting 'float' to 'double' and vice versa; this is
5438 easier to understand and avoids a GCC warning.
5440 2012-04-09 Glenn Morris <rgm@gnu.org>
5442 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5443 preparation for dumping it with emacs. (Bug#4789)
5444 (leimdir): New variable.
5445 ($(leimdir)/leim-list.el): New rule.
5446 (emacs$(EXEEXT)): Depend on leim-list.el.

5452 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5454 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5457 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5459 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5460 Remove unused local variable.
5462 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5464 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5465 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5466 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5467 objects, as mark_maybe_pointer will catch them otherwise.
5468 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5469 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5471 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5473 Fix typo that broke non-Windows builds.
5474 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5476 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5478 Support building on MS-Windows with libxml2.
5480 * makefile.w32-in (OBJ2): Add xml.$(O).
5481 (GLOBAL_SOURCES): Add xml.c.
5482 ($(BLD)/xml.$(O)): New dependency list.
5484 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5485 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5486 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5487 [!WINDOWSNT]: New macros.
5488 (init_libxml2_functions, libxml2_loaded_p): New functions.
5489 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5490 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5491 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5492 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5494 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5495 Call init_libxml2_functions before calling libxml2 functions.
5496 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5498 * emacs.c: Don't include libxml/parser.h.
5499 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5500 xmlCleanupParser directly.
5502 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5504 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5506 * indent.c (Fvertical_motion): If there is a display string at
5507 point, use it.vpos to compute how many lines to backtrack after
5508 move_it_to point. (Bug#11133)
5510 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5512 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5513 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5514 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5515 macros related to unification of CJK characters. For the details,
5516 see the discussion following the message here:
5517 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5519 2012-04-04 Chong Yidong <cyd@gnu.org>
5521 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5523 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5525 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5526 instead of alloca. (Bug#11138)
5528 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5530 * w32menu.c (is_simple_dialog): Properly check lisp types.
5533 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5535 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5536 position we get to after a call to move_it_to fails the
5537 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5538 only if we wind up in a string from display property. (Bug#11063)
5540 * window.c (Fdelete_other_windows_internal): Invalidate the row
5541 and column information about mouse highlight, so that redisplay
5542 restores it after reallocating the glyph matrices. (Bug#7464)
5544 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5545 string comes from a `display' text property, use the buffer
5546 position of that property as if we actually saw that position in
5548 (move_it_by_lines): Remove the assertion that
5549 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5550 violated when there's a before-string at the beginning of a line.
5553 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5555 * xdisp.c (append_space_for_newline): If the default face was
5556 remapped, use the remapped face for the appended newline.
5557 (extend_face_to_end_of_line): Use the remapped default face for
5558 extending the face to the end of the line.
5559 (display_line): Call extend_face_to_end_of_line when the default
5560 face was remapped. (Bug#11068)
5562 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5564 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5566 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5568 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5570 2012-03-27 Glenn Morris <rgm@gnu.org>
5572 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5575 2012-03-26 Kenichi Handa <handa@m17n.org>
5577 * dispextern.h (struct glyph): Fix previous change. Change the
5578 bit length of glyphless.ch to 25 (Bug#11082).
5580 2012-03-26 Chong Yidong <cyd@gnu.org>
5582 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5583 (command_loop_1): Use it; inhibit selection update for
5584 handle-select-window too (Bug#8996).
5586 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5588 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5590 2012-03-25 Kenichi Handa <handa@m17n.org>
5592 * dispextern.h (struct glyph): Change the bit length of
5593 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5595 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5597 * s/ms-w32.h (tzname): Include time.h before redirecting to
5598 _tzname. Fixes the MSVC build. (Bug#9960)
5600 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5602 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5605 * xterm.c (XTread_socket): Only modify handling_signal if
5606 !SYNC_INPUT. (Bug#11080)
5608 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5610 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5611 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5612 when fetching a multibyte character consumes more bytes than
5613 CHAR_BYTES returns, due to unification of CJK characters in
5614 string_char. (Bug#11073)
5616 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5618 * process.c (wait_reading_process_output): Handle pty disconnect
5619 by refraining from sending oneself a SIGCHLD (bug#10933).
5621 2012-03-22 Chong Yidong <cyd@gnu.org>
5623 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5625 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5626 Mark string as coming from a prefix property.
5627 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5628 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5630 2012-03-21 Chong Yidong <cyd@gnu.org>
5632 * xfaces.c (Vface_remapping_alist): Doc fix.
5634 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5636 * w32proc.c (Fw32_set_console_codepage)
5637 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5640 2012-03-20 Chong Yidong <cyd@gnu.org>
5642 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5643 to reflect default non-nil value of redisplay-dont-pause.
5645 2012-03-19 Kenichi Handa <handa@m17n.org>
5647 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5648 it fit in a valid range (Bug#11003).
5650 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5652 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5653 that is not from display property, accept the row as a "cursor
5654 row" if one of the string's character has a non-nil `cursor'
5655 property. Fixes cursor positioning when there are newlines in
5656 overlay strings, e.g. in icomplete.el. (Bug#11035)
5658 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5660 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5662 2012-03-12 Chong Yidong <cyd@gnu.org>
5664 * eval.c (inhibit_lisp_code): Rename from
5665 inhibit_window_configuration_change_hook; move from window.c.
5667 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5668 * window.c (run_window_configuration_change_hook)
5669 (syms_of_window): Callers changed.
5671 2012-03-11 Chong Yidong <cyd@gnu.org>
5673 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5675 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5677 2012-03-10 Chong Yidong <cyd@gnu.org>
5679 * frame.c (other_visible_frames): Don't assume the selected frame
5680 is visible (Bug#10955).
5682 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5684 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5686 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5688 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5689 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5692 2012-03-03 Glenn Morris <rgm@gnu.org>
5694 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5696 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5698 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5699 position past the first glyph_row that ends at ZV. (Bug#10902)
5700 (redisplay_window, next_element_from_string): Fix typos in
5702 (redisplay_window): Pass to move_it_vertically the margin in
5703 pixels, not in screen lines.
5705 2012-03-02 Glenn Morris <rgm@gnu.org>
5707 * buffer.c (buffer-list-update-hook): Doc fix.
5709 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5711 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5712 push_it before setting up the iterator for the first overlay
5713 string, even if we have an empty string loaded.
5714 (next_overlay_string): If there's an empty string on the iterator
5715 stack, pop the stack. (Bug#10903)
5717 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5719 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5720 Suggested by Stefan Monnier in
5721 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5722 * alloc.c (widen_to_Lisp_Object): New static function.
5723 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5724 and widening them to Lisp_Objects. This would work even if
5725 USE_LSB_TAG is defined and wide integers are used, which might
5726 happen in a future version of Emacs.
5728 2012-02-25 Chong Yidong <cyd@gnu.org>
5730 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5733 * xselect.c (Fx_selection_exists_p): Doc fix.
5734 (x_clipboard_manager_save_all): Print an informative message
5735 before saving to clipboard manager.
5737 2012-02-24 Chong Yidong <cyd@gnu.org>
5739 * keyboard.c (process_special_events): Handle all X selection
5740 requests in kbd_buffer, not just the next one (Bug#8869).
5742 2012-02-23 Chong Yidong <cyd@gnu.org>
5744 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5745 call when setting menu-bar-lines and tool-bar-lines parameters.
5746 (unwind_create_frame_1): New helper function.
5748 * window.c (inhibit_window_configuration_change_hook): New var.
5749 (run_window_configuration_change_hook): Obey it.
5750 (syms_of_window): Initialize it.
5752 2012-02-22 Chong Yidong <cyd@gnu.org>
5754 * xterm.c (x_draw_image_relief): Add missing type check for
5755 Vtool_bar_button_margin (Bug#10743).
5757 2012-02-21 Chong Yidong <cyd@gnu.org>
5759 * fileio.c (Vfile_name_handler_alist): Doc fix.
5761 * buffer.c (Fget_file_buffer): Protect against invalid file
5762 handler return value.
5764 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5766 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5767 when computing $valmask.
5769 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5770 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5771 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5772 It's useless in that case, and it can cause problems on hosts
5773 that allocate halves of EMACS_INT values separately.
5774 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5775 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5776 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5777 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5778 it avoids undefined behavior on hosts where shifting right by more
5779 than the word width has undefined behavior.
5781 2012-02-19 Chong Yidong <cyd@gnu.org>
5783 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5784 (Funhandled_file_name_directory, Ffile_name_as_directory)
5785 (Fdirectory_file_name, Fexpand_file_name)
5786 (Fsubstitute_in_file_name): Protect against invalid file handler

6567 to 4 (xorl, subq, cmpq, setbe).
6568 * alloc.c (pure): Always extern now, since that's the
6569 VIRT_ADDR_VARIES behavior.
6570 (PURE_POINTER_P): Use a single comparison, not two, for
6571 consistency with the new puresize.h.
6572 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6581 behave as if the cursor position were at the window margin.
6583 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6584 and the cursor position is out of bounds, behave as if the cursor
6585 position were at the window margin. (Bug#10075)

6612 (compute_line_metrics): Call row_hash, instead of computing the
6615 * dispnew.c (verify_row_hash): Call row_hash for computing the
6616 hash code of a row, instead of duplicating code from xdisp.c.
6618 * dispextern.h (row_hash): Add prototype.
6620 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6622 * frame.c (delete_frame): Don't delete the terminal when the last

6777 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6778 This is also needed for porting to any host where GC_MARK_STACK is
6779 not GC_MAKE_GCPROS_NOOPS.
6780 (which_symbols): Use it.
6782 2011-11-07 Kenichi Handa <handa@m17n.org>
6784 * coding.c (coding_set_destination): Check coding->src_pos only
6785 when coding->src_object is a buffer (bug#9910).

6795 * xmenu.c (cleanup_widget_value_tree): New function.
6796 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
6797 calling free_menubar_widget_value_tree directly (Bug#9830).
6799 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
6801 Fix some portability problems with 'inline'.
6802 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6803 (window_box_width, window_box_left, window_box_left_offset)
6804 (window_box_right, window_box_right_offset): Declare extern.
6805 Otherwise, these inline functions do not conform to C99 and
6806 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6807 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6808 * intervals.c (adjust_intervals_for_insertion)
6809 (adjust_intervals_for_deletion): Now extern, because otherwise the
6810 extern inline functions 'offset_intervals' couldn't refer to it.
6811 (static_offset_intervals): Remove.
6812 (offset_intervals): Rewrite using the old contents of
6813 static_offset_intervals. The old version didn't conform to C99
6814 because an extern inline function contained a reference to an
6815 identifier with static linkage.
6817 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6819 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6837 (Fwindow_vscroll): Doc fix.
6838 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6839 argument, since it makes no sense to pass a live window and for
6840 consistency with window-child.

6868 (unwind_create_frame): New function (Bug#9943).
6869 (Fx_create_frame): Restructure code to be more similar to the one in
6870 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6871 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6872 Move terminal->reference_count++ just before making the frame official

6921 * xdisp.c (note_mouse_highlight): If either of
6922 previous/next-single-property-change returns nil, treat that as

6986 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6987 so that this new function doesn't get optimized away by a

6990 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>

7050 (w32font_open_internal, compute_metrics):
7051 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7052 instead of calling the "wide" APIs directly.
7054 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

7070 non-NULL, regardless of GNUTLS_INITSTAGE.
7071 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7072 an error. Set process slots as soon as we allocate them.

7118 current character, check also for next_en_type being WEAK_EN.
7119 (bidi_resolve_weak): Don't enter the expensive loop if the current
7120 position is before next_en_pos. Record the bidi type of the first
7121 non-ET, non-BN character we find, in addition to its position.
7122 (bidi_level_of_next_char): Invalidate next_en_type when
7123 next_en_pos is over-stepped.
7125 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7127 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7128 * editfns.c: Rewrite current-time-zone so that it invokes
7129 the equivalent of (format-time-string "%Z") to get the time zone name.
7130 This fixes a bug when the time zone name contains characters that
7131 need converting from the system time locale to Emacs internal format.
7132 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7133 that patch fixed format-time-string to do the conversion, but
7134 I forgot to fix current-time-zone.
7135 (format_time_string): New function, containing most of
7136 what Fformat_time_string used to contain.
7137 (Fformat_time_string): Rewrite in terms of format_time_string.
7138 This doesn't change this function's behavior.
7139 (current-time-zone): Rewrite to use format_time_string.
7140 This fixes the bug reported by Michael Schierl in
7141 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7142 Jason Rumney's 2007-06-07 change worked around this bug, but
7144 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7146 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7148 * xdisp.c (start_display): If the character at POS is displayed
7149 via a display vector, reset IT->current.dpvec_index to zero.
7150 (try_window_reusing_current_matrix): If a line ends in a display
7151 vector or the next line starts in a display vector, continue
7152 redrawing the window even though the character position of
7153 start_row was reached.
7156 2011-10-18 Chong Yidong <cyd@gnu.org>
7158 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7159 with nobreak-char-display too.
7161 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7163 Fix part 3 of bug#9771.
7164 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7165 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7166 non-neutral characters if the current character is a paragraph
7167 separator (a.k.a. Newline). This avoids running the same
7168 expensive loop twice, once when we consume the preceding newline
7169 and the other time when the line actually needs to be displayed.
7170 Avoid the loop when we see neutrals on the base embedding level
7171 following a character whose directionality is the same as the
7172 paragraph's. This avoids running the expensive loop when a line
7173 ends in a long sequence of neutrals, like control characters.
7174 Add assertion against STRONG_AL type. Slightly rearrange code
7175 that determines the type of a neutral given the first non-neutral
7177 (bidi_level_of_next_char): Set next_en_pos to zero when
7178 invalidating its info.
7180 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7182 * xdisp.c (push_display_prop): Determine whether to record string
7183 or buffer position by IT->string, not by IT->method. Allow
7184 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7185 (move_it_vertically_backward): Don't look for character position
7186 immediately after the newline when in a continuation line.
7189 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7191 * window.c (coordinates_in_window): Rewrite and delabelize
7192 vertical border check. (Bug#5357) (Bug#9618)
7194 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7196 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained

7201 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7202 avoid crash when xmalloc overrun checking is enabled.
7204 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7206 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7207 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7208 cursor motion with <left> and <right> arrow keys.
7210 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7211 some callers set that themselves.
7213 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7215 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7216 display string and the previous row comes from the same string and
7217 is empty. (Bug#9739) (Bug#9738)
7219 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7221 * doc.c (get_doc_string): Encode file name (bug#9735).
7223 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7225 * bidi.c (bidi_level_of_next_char):
7226 * xdisp.c (get_visually_first_element): Remove old incorrect
7227 comments regarding the Unicode Line Separator character.
7229 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7231 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

7239 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7240 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7242 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7243 Some packages use them to denote characters with modifiers.

7247 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7248 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7249 matching a pp-number. Rename parameter var to var1.
7251 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7253 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7255 2011-10-08 Glenn Morris <rgm@gnu.org>
7257 * callint.c (Fcall_interactively): Give a more explicit error for the
7258 'c' case with a non-character input. (Bug#8479)
7260 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7262 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7264 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7265 lines that are hscrolled on the left.
7267 * dispnew.c (buffer_posn_from_coords): Account for a possible
7268 presence of header-line. (Bug#4426)
7270 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7272 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7273 Don't advertise functionality which we discourage or doesn't work.
7275 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7277 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7278 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7279 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7280 this makes Emacs dump core during garbage collection on rare
7281 occasions. sizeof is obviously inferior to offsetof here, so
7282 stick with offsetof.
7283 (GC_POINTER_ALIGNMENT): New macro.
7284 (mark_memory): Omit 3rd (offset) arg; caller changed.
7285 Don't assume EMACS_INT alignment is the same as pointer alignment.
7287 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7289 * keyboard.c (read_key_sequence_remapped): New var.
7290 (read_key_sequence): Compute remapping in the right buffer.
7291 (command_loop_1): Use read_key_sequence's remapping directly.
7293 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7295 * dired.c (file_name_completion): Don't expand file name.
7296 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7297 before checking file name handler.
7299 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7300 they've been requested explicitly (bug#9591).
7302 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7304 * keymap.c (Fsingle_key_description): Use make_specified_string
7305 instead of build_string to build string from push_key_description.
7308 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7310 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7311 This fixes a Y2038 bug on 64-bit hosts.
7312 * buffer.c (reset_buffer):
7313 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7314 (Fclear_buffer_auto_save_failure):
7315 Use 0, not -1, to represent an unset failure time, since time_t
7316 might not be signed.
7318 Remove dependency on glibc malloc internals.
7319 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7320 Move back here from lisp.h, but with their new implementations.
7321 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7322 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7323 * charset.c (charset_table_init): New static var.
7324 (syms_of_charset): Use it instead of xmalloc. This removes a
7325 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7326 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7327 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7328 Move back to alloc.c.
7329 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7330 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7332 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7334 * nsterm.m (windowDidResize): Call x_set_window_size only when
7335 ns_in_resize is true. Otherwise set pixelwidth/height and
7336 call change_frame_size (Bug#9628).
7338 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7340 Port --enable-checking=all to Fedora 14 x86-64.
7341 * charset.c (syms_of_charset): Also account for glibc malloc's
7342 internal overhead when calculating the initial malloc maximum.
7344 Port --enable-checking=all to Fedora 14 x86.
7345 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7347 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7348 (overrun_check_realloc, overrun_check_free):
7349 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7350 That way, xmalloc returns a properly-aligned pointer even if
7351 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7352 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7353 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7354 into account when calculating the initial malloc maximum.
7355 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7356 Move here from alloc.c, so that charset.c can use it too.
7357 Properly align; the old code wasn't right for common 32-bit hosts
7358 when configured with --enable-checking=all.
7359 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7360 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7362 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7364 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7367 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7369 * xdisp.c (compute_display_string_end): If there's no display
7370 string at CHARPOS, return -1.
7372 * bidi.c (bidi_fetch_char): When compute_display_string_end
7373 returns a negative value, treat the character as a normal
7374 character not covered by a display string. (Bug#9624)
7376 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7378 * lread.c (Fread_from_string): Fix typo in docstring.
7380 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7382 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7383 newline, reseat the iterator instead of bidi-iterating there one
7384 character at a time. (Bug#9610)
7385 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7386 TO_CHARPOS if the bidi iterator is at base embedding level.
7388 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7390 * lread.c (readevalloop): Use correct code for NBSP.
7391 (read1): Likewise. (Bug#9608)
7393 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7395 * dbusbind.c (Fdbus_register_signal): When service is not
7396 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7398 2011-09-25 Glenn Morris <rgm@gnu.org>
7400 * buffer.c (truncate-lines): Doc fix.
7402 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7404 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7405 (Fset_window_next_buffers): Doc fix.
7407 2011-09-24 Glenn Morris <rgm@gnu.org>
7409 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7411 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7413 Fix minor problems found by static checking.
7414 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7415 * indent.c (Fvertical_motion): Fix == vs = typo.
7417 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7419 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7420 Default value is now t. Doc fix.
7422 * indent.c (Fvertical_motion): Compute and apply the overshoot
7423 logic when moving up, not only when moving down. Fix the
7424 confusing name and values of the it_overshoot_expected variable;
7425 logic changes accordingly. (Bug#9254) (Bug#9549)
7427 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7428 CHARPOS is covered by a display string which includes newlines.
7429 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7430 is covered by a display string with embedded newlines.
7432 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7434 * dbusbind.c (Fdbus_register_signal): Add match rule to
7435 Vdbus_registered_objects_table. (Bug#9581)
7436 (Fdbus_register_method, Vdbus_registered_objects_table):
7439 2011-09-24 Jim Meyering <meyering@redhat.com>
7441 do not ignore write error for any output size
7442 The previous change was incomplete.
7443 While it makes emacs --batch detect the vast majority of stdout
7444 write failures, errors were still ignored whenever the output size is
7445 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7446 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7447 && echo FAIL: ignored write error
7448 FAIL: ignored write error
7449 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7450 && echo FAIL: ignored write error
7451 FAIL: ignored write error
7452 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7454 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7456 * emacs.c (Fkill_emacs): In noninteractive mode exit
7457 non-successfully if a write error occurred on stdout. (Bug#9574)
7459 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7461 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7464 * dispextern.h (struct it): Update the comment documenting what
7467 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7469 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7470 a display string, extend search for cursor position to end of row.
7471 (find_row_edges): If the row ends in a newline from a display
7472 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7473 Handle the case of a display string with multiple newlines.
7474 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7475 non-empty line. Fixes confusing cursor motion with arrow keys at
7476 the beginning of a line that starts with whitespace.
7478 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7480 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7483 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7485 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7488 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7490 * xdisp.c (display_line): Record maximum and minimum buffer
7491 positions even if no glyphs were produced (e.g., by a zero-width
7492 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7493 buffer positions that will be removed from the glyph row because
7495 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7496 column is beyond frame width: don't subtract 1 "pixel" when
7497 computing width of the stretch.
7498 (reseat_at_next_visible_line_start): Undo the change made on
7499 2011-09-17 that saved paragraph information and restored it after
7500 the call to `reseat'. (Bug#9545)
7502 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7504 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7505 and turn window cursor on if cleared (Bug#9415).
7507 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7509 * search.c (boyer_moore): Take unibyte characters from pattern
7510 literally. (Bug#9458)
7512 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7514 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7516 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7518 Fix minor problem found by static checking.
7519 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7520 initialized, to pacify gcc -Wuninitialized.
7522 * fileio.c: Report proper errno when syscall falls.
7523 (Finsert_file_contents): Save and restore errno,
7524 so that report_file_error outputs the correct diagnostic.
7525 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7527 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7529 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7531 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7533 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7534 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7536 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7538 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7539 about the current paragraph and restore it after the call to reseat.
7541 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7542 (bidi_find_paragraph_start): Search back for paragraph beginning
7543 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7544 (bidi_move_to_visually_next): Only trigger paragraph-related
7545 computations when the last character is a newline or at EOB, not
7546 just any NEUTRAL_B. (Bug#9470)
7548 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7549 truncated lines if point is covered by a display string. (Bug#9524)
7551 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7553 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7554 (cons_to_x_long): New function.
7555 (lisp_data_to_selection_data): Use it. Correct the test for
7556 short-versus-long data; it was negated. Break out of vector
7557 loop, for efficiency, when a long datum is discovered.
7559 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7561 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7563 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7565 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7566 GCC PR/17406) by declaring this function with external scope.
7568 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7570 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7571 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7573 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7575 * editfns.c (Fformat): Correctly handle text properties on "%%".
7577 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7579 * xterm.c (x_draw_composite_glyph_string_foreground):
7580 * w32term.c (x_draw_composite_glyph_string_foreground):
7581 * term.c (encode_terminal_code):
7582 * composite.c (composition_update_it, get_composition_id):
7583 * xdisp.c (get_next_display_element)
7584 (fill_composite_glyph_string): Add comments about special meaning
7585 of TAB characters in a composition.
7587 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7589 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7590 This occurs when processing a multibyte format.
7591 Problem reported by Wolfgang Jenker.
7593 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7595 * xdisp.c (try_cursor_movement): Only check for exact match if
7596 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7598 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7600 Remove unused external symbols.
7601 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7602 * xdisp.c (calc_pixel_width_or_height): Now static.
7603 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7604 * indent.c (check_display_width):
7605 * w32term.c: Fix comment to match code.
7606 * xterm.c, xterm.h (x_catching_errors): Remove.
7608 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7610 * xselect.c: Use signed conversions more consistently (Bug#9498).
7611 (selection_data_to_lisp_data): Assume incoming selection data are
7612 signed integers, not unsigned. This is to be consistent with
7613 outgoing selection data, which was modified to use signed integers
7614 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7615 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7616 expects long, not unsigned long.
7618 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7620 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7621 computation of loop end. Reported by Johan Bockgård
7624 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7626 * frame.c (Fother_visible_frames_p): Function deleted.
7628 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7630 * indent.c (compute_motion): Process display vector front to back
7631 rather than the other way around. (Bug#2496)
7633 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7635 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7637 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7639 * minibuf.c (Fread_from_minibuffer): Doc fix.
7641 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7643 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7644 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7646 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7648 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7649 value for non-existent files.
7651 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7653 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7654 set its "size" to -1. This will set the modtime_size field of
7655 the corresponding buffer to -1, which is what
7656 verify-visited-file-modtime expects for files that do not exist.
7659 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7661 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7663 * lisp.h: ... from here. push_key_description is no longer
7664 defined in keyboard.c, so its declaration should not be in
7665 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7666 logically belongs with push_key_description.
7668 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7670 * buffer.h: Include <sys/types.h> instead of <time.h>.
7671 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7672 Problem reported by Herbert J. Skuhra.
7674 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7676 * xml.c (parse_region): Make the parsing work for
7677 non-comment-starting XML files again (bug#9144).
7679 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7681 * image.c (gif_load): Fix calculation of bottom and right corner.
7684 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7686 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7687 redisplay in small windows.
7689 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7691 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7693 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7695 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7696 Operate on live windows only.
7698 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7700 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7702 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7704 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7705 only under bidi iteration.
7707 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7709 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7711 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7713 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7714 Without this fix, the command to link temacs failed due to an
7715 undefined symbol __builtin_isnan. This is because
7716 /usr/include/iso/math_c99.h #defines isnan(x) to
7717 __builtin_isnan(x), but the bundled gcc, which identifies itself
7718 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7720 * floatfns.c (isnan): #undef, and then #define to a clone of
7722 (Fisnan): Always define, since it's always available now.
7723 (syms_of_floatfns): Always define isnan at the Lisp level.
7725 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7727 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7729 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7731 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7732 The previous code assumed that file offsets (off_t values) fit in
7733 EMACS_INT variables, which is not true on typical 32-bit hosts.
7734 The code messed up by falsely reporting buffer overflow in cases
7735 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7736 when "big" contains more than 2**29 bytes, even though this
7737 inserts just one byte and does not overflow the buffer.
7738 (Finsert_file_contents): Store file offsets as off_t
7739 values, not as EMACS_INT values. Check for overflow when
7740 converting between EMACS_INT and off_t. When checking for
7741 buffer overflow or for overlap, take the offsets into account.
7742 Don't use EMACS_INT for small values where int suffices.
7743 When checking for overlap, fix a typo: ZV was used where
7744 ZV_BYTE was intended.
7745 (Fwrite_region): Don't assume off_t fits into 'long'.
7746 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7748 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7750 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7752 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7754 sprintf-related integer and memory overflow issues (Bug#9412).
7756 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7757 (esprintf, exprintf, evxprintf): New functions.
7758 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7759 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7760 (modify_event_symbol): Do not assume that the length of
7761 name_alist_or_stem is safe to alloca and fits in int.
7762 (Fexecute_extended_command): Likewise for function name and binding.
7763 (Frecursion_depth): Wrap around reliably on integer overflow.
7764 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7765 since some callers pass EMACS_INT values.
7766 (Fsingle_key_description): Don't crash if symbol name contains more
7767 than MAX_ALLOCA bytes.
7768 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7769 (get_minibuffer): Arg is now EMACS_INT, not int.
7770 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7771 (esprintf, exprintf, evxprintf): New decls.
7772 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7774 * dbusbind.c (signature_cat): New function.
7775 (xd_signature, Fdbus_register_signal):
7776 Do not overrun buffer; instead, report string overflow.
7778 * dispnew.c (add_window_display_history): Don't overrun buffer.
7779 Truncate instead; this is OK since it's just a log.
7781 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7782 even if the time zone offset is outlandishly large.
7783 Don't mishandle offset == INT_MIN.
7785 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7786 when creating daemon; the previous buffer-overflow check was incorrect.
7788 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7789 which has the guts of the old verror function.
7791 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7792 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7794 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7795 (font_unparse_xlfd): Don't blindly alloca long strings.
7796 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7797 fits in int, when using sprintf. Use single snprintf to count
7798 length of string rather than counting it via multiple sprintfs;
7799 that's simpler and more reliable.
7800 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7801 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7802 sprintf, in case result does not fit in int.
7804 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7805 (fontset_from_font): Print it.
7807 * frame.c (tty_frame_count): Now printmax_t, not int.
7808 (make_terminal_frame, set_term_frame_name): Print it.
7809 (x_report_frame_params): In X, window IDs are unsigned long,
7810 not signed long, so print them as unsigned.
7811 (validate_x_resource_name): Check for implausibly long names,
7812 and don't assume name length fits in 'int'.
7813 (x_get_resource_string): Don't blindly alloca invocation name;
7814 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7817 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7818 (xg_check_special_colors, xg_set_geometry):
7819 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7821 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7822 Use esprintf, not sprintf, in case result does not fit in int.
7824 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7825 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7826 it as a large positive number.
7827 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7828 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7830 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7831 in case result does not fit in int.
7833 * print.c (float_to_string): Detect width overflow more reliably.
7834 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7835 buffer overrun. Don't assume list length fits in 'int'. Treat
7836 print length of 0 as 0, not as infinity; to be consistent with other
7837 uses of print length in this function. Don't overflow print length
7838 index. Don't assume hash table size fits in 'long', or that
7839 vectorlike size fits in 'unsigned long'.
7841 * process.c (make_process): Use printmax_t, not int, to format
7842 process-name gensyms.
7844 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7846 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7847 to avoid potential buffer overrun.
7849 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7850 if X resource line is longer than 512 bytes.
7852 * xfns.c (x_window): Make sprintf buffer a bit bigger
7853 to avoid potential buffer overrun.
7855 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7857 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7859 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7861 Integer overflow fixes for scrolling, etc.
7862 Without these, Emacs silently mishandles large integers sometimes.
7863 For example, "C-u 4294967297 M-x recenter" was treated as if
7864 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7866 * xdisp.c (try_window_id): Check Emacs fixnum range before
7867 converting to 'int'.
7869 * window.c (window_scroll_line_based, Frecenter):
7870 Check that an Emacs fixnum is in range before assigning it to 'int'.
7871 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7872 values converted from Emacs fixnums.
7873 (Frecenter): Don't wrap around a line count if it is out of 'int'
7874 range; instead, treat it as an extreme value.
7875 (Fset_window_configuration, compare_window_configurations):
7876 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7878 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7879 that can exceed INT_MAX. Check that EMACS_INT value is in range
7880 before assigning it to the (possibly-narrower) index.
7881 (match_limit): Don't assume that a fixnum can fit in 'int'.
7883 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7886 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7887 (Fvertical_motion): Don't wrap around LINES values that don't fit
7888 in 'int'. Instead, treat them as extreme values. This is good
7889 enough for windows, which can't have more than INT_MAX lines anyway.
7891 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7893 * Require libxml/parser.h to avoid compilation warning.
7895 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7897 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7898 since this reportedly can destroy thread storage.
7900 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7902 * syntax.c (find_defun_start): Update all cache variables if
7903 exiting early (Bug#9401).
7905 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7907 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7909 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7910 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7911 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7913 * term.c (tty_append_glyph): New function.
7914 (produce_stretch_glyph): Static function and its prototype deleted.
7916 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7919 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7921 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7922 when checking :margin (Bug#9390).
7923 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7924 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7925 so that the name doesn't mislead. All uses changed.
7927 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7929 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7932 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7934 * xdisp.c (move_it_to): Don't bail out early when reaching
7935 position beyond to_charpos, if we are scanning backwards.
7936 (move_it_vertically_backward): When DY == 0, make sure we get to
7937 the first character in the line after the newline.
7939 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7941 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7942 (ccl_driver): Do not generate an out-of-range pointer.
7943 (Fccl_execute_on_string): Remove unnecessary check for
7944 integer overflow, noted by Stefan Monnier in
7945 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7946 Remove a FIXME that didn't need fixing.
7947 Simplify the newly-introduced buffer reallocation code.
7949 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7951 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7953 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7955 Integer and memory overflow issues (Bug#9196).
7957 * doc.c (get_doc_string): Rework so that
7958 get_doc_string_buffer_size is the actual buffer size, rather than
7959 being 1 less than the actual buffer size; this makes xpalloc more
7962 * image.c (x_allocate_bitmap_record, cache_image):
7963 * xselect.c (Fx_register_dnd_atom):
7964 Simplify previous changes by using xpalloc.
7966 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7967 since either will do and ptrdiff_t is convenient with xpalloc.
7969 * charset.c (charset_table_size)
7970 (struct charset_sort_data.priority): Now ptrdiff_t.
7971 (charset_compare): Don't overflow if priorities differ greatly.
7972 (Fsort_charsets): Don't assume list length fits in int.
7973 Check for size-calculation overflow when allocating sort data.
7974 (syms_of_charset): Allocate an initial charset table that is
7975 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7977 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7979 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7980 The actual value is always <= INT_MAX, and leaving it unsigned made
7981 overflow checking harder.
7983 * dispextern.h (struct glyph_matrix.rows_allocated)
7984 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7985 with xpalloc. The values are still always <= INT_MAX.
7987 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7989 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7990 (SAFE_NALLOCA): New macro.
7992 * region-cache.c (struct boundary.pos, find_cache_boundary)
7993 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7994 (set_cache_region, invalidate_region_cache)
7995 (revalidate_region_cache, know_region_cache, region_cache_forward)
7996 (region_cache_backward, pp_cache):
7997 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7998 so that ptrdiff_t * can be passed to xpalloc.
7999 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8000 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8001 (pp_cache): Don't assume cache_len fits in int.
8002 * region-cache.h: Adjust extern decls to match.
8004 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8005 EMACS_INT, since either will do, for xpalloc.
8007 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8008 (xnmalloc, xnrealloc, xpalloc): New functions.
8010 * bidi.c (bidi_shelve_header_size): New constant.
8011 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8012 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8014 * bidi.c (bidi_cache_shrink):
8015 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8017 Don't update size of array until after memory allocation succeeds,
8018 because xmalloc/xrealloc may not return.
8019 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8020 now that we have proper integer overflow checking.
8021 (record_overlay_string, overlay_strings): Catch overflows when
8022 calculating size of overlay_str_buf.
8024 * callproc.c (Fcall_process): Check for size overflow when
8025 calculating size of args2.
8026 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8027 Normally we prefer signed values, but sticking with ptrdiff_t would
8028 require adding more-complicated checks.
8030 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8031 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8032 Redo buffer-overflow calculations to avoid integer overflow.
8033 Add a FIXME comment where memory seems to be over-allocated.
8035 * character.c (Fstring): Check for size-calculation overflow.
8037 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8038 unnecessary integer overflow. Check for size overflow.
8039 (encode_coding_object): Don't update size until xmalloc succeeds.
8041 * composite.c (get_composition_id): Check for overflow in glyph
8042 length calculations.
8044 Integer and memory overflow fixes for display code.
8045 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8046 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8047 (scrolling_window): Check for overflow in size calculations.
8048 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8049 Don't assume glyph table len fits in int.
8050 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8051 (row_table_size): Now ptrdiff_t, not int.
8052 (scrolling_window): Avoid overflow in size calculations.
8053 Don't update size until allocation succeeds.
8054 * fns.c (concat): Check for overflow in size calculations.
8055 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8056 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8057 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8059 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8060 (get_doc_string): Check for size calculation overflow.
8061 Don't update size until allocation succeeds.
8062 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8063 EMACS_INT, where ptrdiff_t will do.
8064 (Fsubstitute_command_keys): Check for string overflow.

8068 (message_length): Now ptrdiff_t, not int.
8069 (Fmessage_box): Don't update size until allocation succeeds.
8070 Don't assume message length fits in int.
8071 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8073 * emacs.c (main): Do not reallocate argv, since there is a null at
8074 the end that can be overwritten, and this way there's no need to
8075 worry about size-calculation overflow.
8076 (sort_args): Check for size-calculation overflow.
8078 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8080 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8082 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8083 (x_set_scroll_bar_width, x_figure_window_size):
8084 Check for integer overflow.
8085 (x_set_alpha): Do not assume XINT fits in int.
8087 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8088 This is for the members text_lines, text_cols, total_lines, total_cols,
8089 where the system imposes an 'int' limit.
8091 * fringe.c (Fdefine_fringe_bitmap):
8092 Don't update size until alloc works.
8094 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8095 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8097 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8098 Check for size-calculation overflow.
8099 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8100 do, as we prefer signed integers.
8101 (id_to_widget.max_size, id_to_widget.used)
8102 (xg_store_widget_in_map, xg_remove_widget_from_map)
8103 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8104 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8105 Use and return ptrdiff_t, not int.
8106 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8107 * gtkutil.h: Change prototypes to match the above.
8109 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8110 are duplicate now that they've been promoted to lisp.h.
8111 (x_allocate_bitmap_record, x_alloc_image_color)
8112 (make_image_cache, cache_image, xpm_load):
8113 Don't update size until alloc is done.
8114 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8116 Check for size calculation overflow.
8117 (ct_colors_allocated_max): New constant.

8124 Use ptrdiff_t, not int, to count maps.
8125 (read_char_minibuf_menu_prompt): Check for overflow in size
8126 calculations. Don't update size until allocation succeeds.

8138 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8140 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8141 Now ptrdiff_t, not int.
8142 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8143 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.

8146 in size calculation.
8148 * region-cache.c (move_cache_gap): Check for size calculation overflow.

8151 overflow. Don't bother calling xmalloc when xrealloc will do.
8153 * search.c (Freplace_match): Check for size calculation overflow.
8154 (Fset_match_data): Don't assume list lengths fit in 'int'.
8156 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8157 for command line length. Do not attempt to address one before the
8158 beginning of an array, as that's not portable.

8161 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8163 (encode_terminal_code, calculate_costs): Check for size
8164 calculation overflow.

8176 Don't update size until alloc done.
8177 Redo size calculations to avoid overflow.

8189 (cache_face): Treat size calculation overflows as if they were
8190 memory exhaustion (the usual treatment), rather than aborting.
8192 * xfns.c (x_encode_text, x_set_name_internal)
8193 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8194 sizes, since they can exceed INT_MAX in size. Check for size
8195 calculation overflow.
8197 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8198 (xg_select): Check for size calculation overflow.
8199 Don't update size until alloc done.
8201 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8202 as sprintf is limited to int lengths.
8204 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8205 (X_LONG_MIN): New macros.
8206 Use them to make the following changes clearer.
8207 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8208 This change doesn't affect the value now, but it may help remind
8209 future maintainers not to raise the value too much later.
8210 (SELECTION_QUANTUM): Remove, replacing with ...
8211 (selection_quantum): ... new function, which avoids overflow.
8213 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8214 assumption that selection length fits in 'int'.
8215 (x_reply_selection_request, x_handle_selection_request)
8216 (x_get_window_property, receive_incremental_selection)
8217 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8218 (lisp_data_to_selection_data, clean_local_selection_data):
8219 Use ptrdiff_t, not int, to record length of selection.
8220 (x_reply_selection_request, x_get_window_property)
8221 (receive_incremental_selection, x_property_data_to_lisp):
8222 Redo calculations to avoid overflow.
8223 (x_reply_selection_request): When sending hint, ceiling it at
8224 X_LONG_MAX rather than relying on wraparound overflow to send
8226 (x_get_window_property, receive_incremental_selection)
8227 (lisp_data_to_selection_data, x_property_data_to_lisp):
8228 Check for size-calculation overflow.
8229 (x_get_window_property, receive_incremental_selection)
8230 (lisp_data_to_selection_data, Fx_register_dnd_atom):
8231 Don't store size until memory allocation succeeds.
8232 (x_get_window_property): Plug memory leak on memory exhaustion.
8233 Don't double-block input; malloc is safe here. Don't assume 2**34
8234 - 4 fits in unsigned long. Add an xassert to check
8235 XGetWindowProperty overflow. Be more careful about overflow
8236 calculations, and distinguish size from memory overflow better.
8237 (receive_incremental_selection): When tracing, don't assume
8238 unsigned int is less than INT_MAX.
8239 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8240 harmful) conversions of unsigned short to int.
8241 (lisp_data_to_selection_data): Don't assume that integers
8242 in the range -65535 through -1 fit in an X unsigned short.
8243 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8244 result parameters unless successful. Rely on cons_to_unsigned
8245 to report problems with elements; the old code wasn't right anyway.
8246 (x_check_property_data): Check for int overflow; we cannot use
8247 a wider type due to X limits.
8248 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8250 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8252 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8253 (x_term_init): Check for size calculation overflow.
8254 (x_color_cells): Don't store size until memory allocation succeeds.
8255 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
8256 Don't assume alloca size is less than MAX_ALLOCA.

8267 Use ptrdiff_t, not int, for composition IDs.
8268 * composite.c (get_composition_id): Check for integer overflow.
8269 * composite.h: Adjust prototypes to match the above changes.
8271 Use ptrdiff_t for hash table indexes.

8279 * image.c (xpm_get_color_table_h):
8280 * lisp.h (hash_lookup, hash_put):
8281 * minibuf.c (Ftest_completion):
8282 Use ptrdiff_t for hash table indexes, not int (which is too
8283 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8284 32-bit --with-wide-int hosts).
8286 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8287 Add a FIXME comment about memory leaks.
8288 (syms_of_charset): Don't assume xmalloc returns.
8290 Don't assume that stated character widths fit in int.
8291 * character.c (Fchar_width, c_string_width, lisp_string_width):
8292 * character.h (CHAR_WIDTH):
8293 * indent.c (MULTIBYTE_BYTES_WIDTH):
8294 Use sanitize_char_width to avoid undefined and/or bad behavior
8295 with outlandish widths.
8296 * character.h (sanitize_tab_width): Rename from sanitize_width,
8297 now that we have two such functions. All uses changed.
8298 (sanitize_char_width): New inline function.
8300 Don't assume that tab-width fits in int.
8301 * character.h (sanitize_width): New inline function.
8302 (SANE_TAB_WIDTH): New macro.
8303 (ASCII_CHAR_WIDTH): Use it.
8304 * indent.c (sane_tab_width): Remove. All uses replaced by
8305 SANE_TAB_WIDTH (current_buffer).
8306 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
8308 * fileio.c: Integer overflow issues with file modes.
8309 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.

8315 * xterm.c: Don't go over XClientMessageEvent limit.
8316 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8317 (x_send_scroll_bar_event): Likewise. Check that the size does not
8318 exceed limits imposed by XClientMessageEvent, as well as the usual
8319 ptrdiff_t and size_t limits.
8321 * keyboard.c: Overflow, signedness and related fixes.
8322 (make_lispy_movement): Use same integer type in forward decl
8323 that is used in the definition.
8324 (read_key_sequence, keyremap_step):
8325 Change bufsize argument back to int, undoing my 2011-03-30 change.
8326 We prefer signed types, and int is wide enough here.
8327 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8328 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8329 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8330 length, not size_t. Use ptrdiff_t for index, not int.
8331 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8332 possibility of integer overflow.
8334 Overflow, signedness and related fixes for images.
8336 * dispextern.h (struct it.stack[0].u.image.image_id)
8337 (struct_it.image_id, struct image.id, struct image_cache.size)

8343 * nsmenu.m (update_frame_tool_bar):
8344 * xdisp.c (calc_pixel_width_or_height):
8345 * xfns.c (image_cache_refcount):
8346 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8347 on typical 64-bit hosts.
8349 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8350 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8355 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8356 (lookup_image): Remove unnecessary tests.
8357 (xbm_image_p): Locals are now of int, not EMACS_INT,
8358 since parse_image_check makes sure they fit into int.
8359 (png_load, gif_load, svg_load_image):
8360 Prefer int to unsigned where either will do.
8361 (tiff_handler): New function, combining the cores of the
8362 old tiff_error_handler and tiff_warning_handler.
8363 This function is rewritten to use vsnprintf and thereby avoid
8364 stack buffer overflows. It uses only the features of vsnprintf
8365 that are common to both POSIX and native Microsoft.
8366 (tiff_error_handler, tiff_warning_handler): Use it.
8367 (tiff_load, gif_load, imagemagick_load_image):
8368 Don't assume :index value fits in 'int'.
8369 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8370 (imagemagick_load_image): Check that crop parameters fit into
8371 the integer types that MagickCropImage accepts. Don't assume
8372 Vimagemagick_render_type has a nonnegative value. Don't assume
8373 size_t fits in 'long'.
8374 (gs_load): Use printmax_t to print the widest integers possible.
8375 Check for integer overflow when computing image height and width.
8377 2011-08-26 Eli Zaretskii <eliz@gnu.org>
8379 * xdisp.c (redisplay_window): Don't force window start if point
8380 will be invisible in the resulting window. (Bug#9324)
8382 2011-08-25 Eli Zaretskii <eliz@gnu.org>
8384 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8385 the display spec is of the form `(space ...)'.
8386 (handle_display_spec): Return the value returned by
8387 handle_single_display_spec, not just 1 or zero.
8388 (handle_single_display_spec): If the display spec is of the form
8389 `(space ...)', and specifies display in the text area, return 2
8391 (try_cursor_movement): Check for the need to scroll more
8392 accurately, and prefer exact match for point under bidi.
8393 Don't advance `row' beyond the last row of the window.
8395 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8396 into disp_prop; all users changed.
8398 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8399 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8400 for the text covered by the display property.
8402 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8404 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8410 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8411 buffers, return left-to-right.
8412 (set_cursor_from_row): Consider candidate row a win if its glyph
8413 represents a newline and point is on that newline. Fixes cursor
8414 positioning on the newline at EOL of R2L text within L2R
8415 paragraph, and vice versa.
8416 (try_cursor_movement): Check continued rows, in addition to
8417 continuation rows. Fixes unwarranted scroll when point enters a
8418 continued line of R2L text within an L2R paragraph, or vice versa.
8419 (cursor_row_p): Consider the case of point being equal to
8420 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8421 from the end of a short line to the beginning of a continued line
8422 of R2L text within L2R paragraph.
8423 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8424 composed characters.
8426 * bidi.c (bidi_check_type): Use xassert.
8427 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8430 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8432 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
8435 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8437 * nsfont.m (ns_otf_to_script): Fix typo.
8439 2011-08-22 Kenichi Handa <handa@m17n.org>
8441 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8442 extra slot even if the purpose is char-code-property-table.
8444 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8446 * xdisp.c (redisplay_window): When computing centering_position,
8447 account for the height of the header line. (Bug#8874)
8449 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8450 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8451 candidate is selected by the mouse, and that candidate has a
8452 composed character under the mouse.
8454 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8455 coordinates reported by pos-visible-in-window-p for a composed
8456 character in column zero.
8458 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8460 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8462 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8464 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8465 consider it a hit if to_charpos is anywhere in the range of the
8466 composed buffer positions.
8468 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8470 * image.c (gif_load): Don't assume that each subimage has the same
8471 dimensions as the base image. Handle disposal method that is
8472 "undefined" by the gif spec (Bug#9335).
8474 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8476 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8477 (Fcondition_case): Document `debug' symbol in error handler.
8479 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8481 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8482 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8483 from an Org mode buffer to a Speedbar frame.
8485 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8486 a composition, take its buffer position from IT->cmp_it.charpos.
8487 Fixes cursor positioning at the beginning of a line that begins
8488 with a composed character.
8490 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8492 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8493 character bidirectional type, use STRONG_L instead. Fixes crashes
8494 in a buffer produced by `describe-categories'.
8496 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8497 members before the level stack, so they would be saved and
8498 restored when copying iterator state. Fixes incorrect reordering
8499 around TABs covered by display properties.
8501 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8503 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
8505 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
8507 * eval.c (internal_condition_case, internal_condition_case_1)
8508 (internal_condition_case_2, internal_condition_case_n):
8509 Remove unnecessary aborts (Bug#9081).
8511 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8513 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8514 has no `load' handler, try opening the file locally. (Bug#9311)
8516 2011-08-16 Ken Brown <kbrown@cornell.edu>
8518 * gmalloc.c: Expand comment.
8520 2011-08-16 Eli Zaretskii <eliz@gnu.org>
8522 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
8523 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8525 2011-08-16 Ken Brown <kbrown@cornell.edu>
8527 Fix memory allocation problems in Cygwin build (Bug#9273).
8529 * unexcw.c ( __malloc_initialized): Declare external variable.
8530 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8532 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8534 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8536 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8538 [CYGWIN] (special_realloc): New function.
8539 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8540 requests to realloc storage in the static heap.
8542 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8544 * bidi.c (bidi_initialize): Remove unused local.

8549 * biditype.h: Remove file.
8550 * makefile.w32-in ($(BLD)/bidi.$(O)):
8551 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8553 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8555 * chartab.c: Improve commentary for the uniprop_table API.
8557 * bidi.c (bidi_paragraph_init): Support zero value of
8558 bidi_ignore_explicit_marks_for_paragraph_level.
8559 (bidi_initialize): Use uniprop_table instead of including
8560 biditype.h and bidimirror.h.
8562 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8563 coordinates of the iterator when restoring from ppos_it.
8566 2011-08-14 Kenichi Handa <handa@m17n.org>
8568 * process.c (create_process): Call setup_process_coding_systems
8569 after the pid of the process is set to -1 (Bug#8162).
8571 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8573 * xdisp.c (move_it_in_display_line_to): Don't invoke
8574 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8575 ppos_it. Fixes vertical cursor motion when line beginning is
8576 covered by an image. (Bug#9296)
8578 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8580 * nsterm.h (ns_run_ascript): Declare.
8581 (NSAPP_DATA2_RUNASSCRIPT): Define.
8583 * nsfns.m (as_script, as_result, as_status): New static variables.
8584 (ns_run_ascript): New function.
8585 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8586 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8587 the event loop. Get status from as_status (Bug#7276).
8589 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8590 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8591 the event loop (Bug#7276).
8593 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8595 * gnutls.c (QCgnutls_bootprop_priority)
8596 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8597 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8598 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

8600 (QCgnutls_bootprop_verify_hostname_error)
8601 (QCgnutls_bootprop_callbacks_verify): Rename from
8602 Qgnutls_bootprop_..., all uses changed.
8604 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8607 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8609 * xfaces.c (Qframe_set_background_mode): Now static.
8610 * dispextern.h (Qframe_set_background_mode): Remove decl.
8612 * process.c (Fnetwork_interface_info): Declare local only if needed.
8614 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8616 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8617 (Fnetwork_interface_list): Allocate in increments of bytes instead
8618 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8619 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8621 (struct ifflag_def): notrailers is smart on OSX.
8622 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8623 Get hardware address with getifaddrs if available.
8625 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8627 * xdisp.c (iterate_out_of_display_property): xassert that
8628 IT->position is set to within IT->object's boundaries. Break from
8629 the loop as soon as EOB is reached; avoids infloops in redisplay
8630 when IT->position is set up wrongly due to some bug.
8631 Set IT->current to match the bidi iterator unconditionally.
8632 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8633 entry. Force push_it to save on the stack the current
8634 buffer/string position, to be restored by pop_it. Fix flags in
8635 the iterator structure wrt the object coming from a display
8636 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8637 properties. (Bug#9284)
8639 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8641 * fontset.c (fontset_get_font_group): Add proper type checks.
8644 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8646 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
8647 and LC_VERSION_MIN_MACOSX.

8653 * xdisp.c (forward_to_next_line_start): Allow to use the
8654 no-display-properties-and-no-overlays under bidi display.
8655 Set disp_pos in the bidi iterator to avoid searches for display
8656 properties and overlays.
8658 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8660 * editfns.c (Fset_time_zone_rule): Document relationship with the
8663 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8664 the font entity extracted from the cache (Bug#8109).
8666 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8668 * composite.c (autocmp_chars): Don't reset point. That is done by
8669 restore_point_unwind (Bug#5984).
8671 2011-08-07 Juri Linkov <juri@jurta.org>
8673 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8674 to show the arg `TIME' instead of `TIMEVAL'.
8676 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8678 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8679 display property strides EOL and includes a newline, as in
8680 longlines-mode. (Bug#9254)
8681 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8682 word-wrap under bidirectional display. (Bug#9224)
8684 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8685 is non-zero, even if the data buffer is NULL. Fixes a crash in
8686 vertical-motion with longlines-mode. (Bug#9254)
8688 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8690 * bidi.c <bidi_cache_total_alloc>: Now static.
8691 (bidi_initialize): Initialize bidi_cache_total_alloc.
8693 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8696 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8697 amount allocated this far in `bidi_cache_total_alloc'.
8698 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8699 non-zero, only free the data buffer without restoring the cache
8700 contents. All callers changed.
8702 * dispextern.h (bidi_unshelve_cache): Update prototype.
8704 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8705 (move_it_in_display_line, move_it_to)
8706 (move_it_vertically_backward, move_it_by_lines): Replace the call
8707 to xfree to an equivalent call to bidi_unshelve_cache.
8708 (move_it_in_display_line_to): Fix logic of returning
8709 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8711 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8713 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8714 came from a string character with a `cursor' property. (Bug#9229)
8716 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8718 * Makefile.in (LIB_PTHREAD): New variable.
8719 (LIBES): Add LIB_PTHREAD (Bug#9216).
8721 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8722 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8724 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8726 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8728 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8730 * xterm.c (x_find_topmost_parent): New function.
8731 (x_set_frame_alpha): Find topmost parent window with
8732 x_find_topmost_parent and set the property there also (bug#9181).
8733 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8735 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8737 * callproc.c (Fcall_process): Avoid vfork clobbering
8738 the local vars buffer, coding_systems, current_dir.
8740 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8742 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8744 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8746 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8747 so that it is not optimized away.
8749 * xdisp.c (compute_display_string_pos): Remove unused local.
8751 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8753 Fix slow cursor motion and scrolling in large buffers with
8754 selective display, like Org Mode buffers. (Bug#9218)
8756 * dispextern.h (struct bidi_it): New member disp_prop_p.
8758 * xdisp.c: Remove one-slot cache of display string positions.
8759 (compute_display_string_pos): Accept an additional argument
8760 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8761 for a display string or property. If found, set DISP_PROP_P
8764 * bidi.c (bidi_fetch_char): Accept an additional argument
8765 DISP_PROP_P, and pass it to compute_display_string_pos.
8766 Only handle text covered by a display string if DISP_PROP_P is returned
8767 non-zero. All callers of bidi_fetch_char changed.
8769 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8771 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8773 2010-12-03 Don March <don@ohspite.net>
8775 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8776 last character M-[char] is translated to ESC [char] (bug#7541).
8778 2011-08-02 Kenichi Handa <handa@m17n.org>
8780 * lisp.h (uniprop_table): Extern it.
8782 * chartab.c (uniprop_table): Make it non-static.
8784 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8786 * xdisp.c (forward_to_next_line_start): Accept additional argument
8787 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8789 (reseat_at_next_visible_line_start): Use the bidi iterator state
8790 returned by forward_to_next_line_start to restore the state of
8791 it->bidi_it after backing up to previous newline. (Bug#9212)
8793 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8795 * regex.c (re_comp): Protoize.
8796 (re_exec): Fix return type.
8797 (regexec): Fix type of `ret'. (Bug#9203)
8799 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8801 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8802 This is needed if max-image-size is a floating-point number.
8804 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8806 * print.c (print_object): Print empty symbol as ##.
8808 * lread.c (read1): Read ## as empty symbol.
8810 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8812 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8813 setting frame foreground color (Bug#9175).
8814 (x_set_background_color): Likewise.
8816 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8817 contents (Bug#9176).
8818 (EmacsTooltip -init): Remove bezels and add shadows to
8821 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8822 or scroll bar (Bug#8470).
8824 * nsfont.m (nsfont_open): Remove assignment to voffset and
8825 unnecessary vars hshink, expand, hd, full_height, min_height.
8826 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8828 * nsterm.h (nsfont_info): Remove voffset field.
8830 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8832 Implement strike-through and overline on NextStep (Bug#8863).
8834 * nsfont.m (nsfont_open): Use underline position provided by font,
8835 instead of hard-coded value of 2.
8836 (nsfont_draw): Call ns_draw_text_decoration instead.
8838 * nsterm.h: Add declaration for ns_draw_text_decoration.
8840 * nsterm.m (ns_draw_text_decoration): New function for drawing
8841 underline, overline, and strike-through.
8842 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8843 ns_draw_text_decoration. Change treatment of cursor drawing to
8844 accommodate underlining, etc.
8846 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8848 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8851 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8853 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8854 Without this fix, if a signal arrives just after memory fills up,
8855 'malloc' might be invoked reentrantly.
8857 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8858 In other words, assume that every image size is allowed, on non-X
8859 hosts. This assumption is probably wrong, but it lets Emacs compile.
8861 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8863 * regex.c (re_iswctype): Convert return values to boolean.
8865 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8867 * xdisp.c (compute_display_string_pos): Don't use cached display
8868 string position if the buffer had its restriction changed.
8871 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8873 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8875 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8877 Integer signedness and overflow and related fixes. (Bug#9079)
8879 * bidi.c: Integer size and overflow fixes.
8880 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8881 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8882 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8883 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8884 (bidi_find_other_level_edge):
8885 Use ptrdiff_t instead of EMACS_INT where either will do.
8886 This works better on 32-bit hosts configured --with-wide-int.
8887 (bidi_cache_ensure_space): Check for size-calculation overflow.
8888 Use % rather than repeated addition, for better worst-case speed.
8889 Don't set bidi_cache_size until after xrealloc returns, because it
8891 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8892 (bidi_cache_ensure_space): Also check that the bidi cache size
8893 does not exceed that of the largest Lisp string or buffer. See Eli
8894 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8896 * alloc.c (__malloc_size_t): Remove.
8897 All uses replaced by size_t. See Andreas Schwab's note
8898 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8900 * image.c: Improve checking for integer overflow.
8901 (check_image_size): Assume that f is nonnull, since
8902 it is always nonnull in practice. This is one less thing to
8903 worry about when checking for integer overflow later.
8904 (x_check_image_size): New function, which checks for integer
8905 overflow issues inside X.
8906 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8907 This removes the need for a memory_full check.
8908 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8909 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8910 (xbm_read_bitmap_data): Change locals back to 'int', since
8911 their values must fit in 'int'.
8912 (xpm_load_image, png_load, tiff_load):
8913 Invoke x_create_x_image_and_pixmap earlier,
8914 to avoid much needless work if the image is too large.
8915 (tiff_load): Treat overly large images as if
8916 x_create_x_image_and_pixmap failed, not as malloc failures.
8917 (gs_load): Use x_check_image_size.
8919 * gtkutil.c: Omit integer casts.
8920 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8921 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8923 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8925 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8926 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8927 would wrongly return t on a 64-bit host.
8929 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8930 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8931 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8932 and therefore cause GCC to emit a bogus diagnostic in some cases.
8934 * image.c: Integer signedness and overflow and related fixes.
8935 This is not an exhaustive set of fixes, but it's time to
8936 record what I've got.
8937 (lookup_pixel_color, check_image_size): Remove redundant decls.
8938 (check_image_size): Don't assume that arbitrary EMACS_INT values
8939 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8940 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8941 (tiff_load, imagemagick_load_image):
8942 Check for overflow in size calculations.
8943 (x_create_x_image_and_pixmap): Remove unnecessary test for
8944 xmalloc returning NULL; that can't happen.
8945 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8946 (xpm_color_bucket): Use better integer hashing function.
8947 (xpm_cache_color): Don't possibly over-allocate memory.
8948 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8949 (gif_memory_source):
8950 Use ptrdiff_t, not int or size_t, to record sizes.
8951 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8952 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8953 either works, as we prefer signed integers.
8954 (tiff_read_from_memory, tiff_write_from_memory):
8955 Return tsize_t, not size_t, since that's what the TIFF API wants.
8956 (tiff_read_from_memory): Don't fail simply because the read would
8957 go past EOF; instead, return a short read.
8958 (tiff_load): Omit no-longer-needed casts.
8959 (Fimagemagick_types): Don't assume size fits into 'int'.
8961 Improve hashing quality when configured --with-wide-int.
8962 * fns.c (hash_string): New function, taken from sxhash_string.
8963 Do not discard information about ASCII character case; this
8964 discarding is no longer needed.
8965 (sxhash-string): Use it. Change sig to match it. Caller changed.
8966 * lisp.h: Declare it.
8967 * lread.c (hash_string): Remove, since we now use fns.c's version.
8968 The fns.c version returns a wider integer if --with-wide-int is
8969 specified, so this should help the quality of the hashing a bit.
8971 * emacs.c: Integer overflow minor fix.
8972 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8973 Define only if GNU_LINUX.
8974 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8976 * dispnew.c: Integer signedness and overflow fixes.
8977 Remove unnecessary forward decls, that were a maintenance hassle.
8978 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8980 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8981 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8982 (prepare_desired_row, line_draw_cost):
8983 Use int, not unsigned, where either works.
8984 (save_current_matrix, restore_current_matrix):
8985 Use ptrdiff_t, not size_t, where either works.
8986 (init_display): Check for overflow more accurately, and without
8987 relying on undefined behavior.
8989 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8990 Remove, replacing with the new symbols in lisp.h. All uses changed.
8991 * fileio.c (make_temp_name):
8992 * filelock.c (lock_file_1, lock_file):
8993 * xdisp.c (message_dolog):
8994 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8995 Use pMd etc. instead.
8996 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8997 replacing the pWIDE etc. symbols removed from editfns.c.
8999 * keyboard.h (num_input_events): Now uintmax_t.
9000 This is (very slightly) less likely to mess up due to wraparound.
9003 * buffer.c: Integer signedness fixes.
9004 (alloc_buffer_text, enlarge_buffer_text):
9005 Use ptrdiff_t rather than size_t when either will do, as we prefer
9008 * alloc.c: Integer signedness and overflow fixes.
9009 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9010 (__malloc_size_t): Default to size_t, not to int.
9011 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9012 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9013 Prefer ptrdiff_t to size_t when either would do, as we prefer
9015 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9016 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9017 Now const. Initialize with values that are in range even if char
9019 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9020 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9021 These functions do the right thing with sizes > 2**32.
9022 (check_depth): Now ptrdiff_t, not int.
9023 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9024 Adjust to new way of storing sizes. Check for size overflow bugs
9026 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9027 slightly wrong anyway, as it missed one instance of
9028 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9029 (refill_memory_reserve): Omit needless cast to size_t.
9030 (mark_object_loop_halt): Mark as externally visible.
9032 * xselect.c: Integer signedness and overflow fixes.
9033 (Fx_register_dnd_atom, x_handle_dnd_message):
9034 Use ptrdiff_t, not size_t, since we prefer signed.
9035 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9036 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9037 x_dnd_atoms_size and x_dnd_atoms_length.
9039 * doprnt.c: Prefer signed to unsigned when either works.
9041 * doprnt.c (doprnt):
9043 * xdisp.c (vmessage):
9044 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9045 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9046 prefer signed arithmetic to avoid comparison confusion.
9047 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9048 but is a bit tricky.
9050 Assume freestanding C89 headers, string.h, stdlib.h.
9051 * data.c, doprnt.c, floatfns.c, print.c:
9052 Include float.h unconditionally.
9053 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9054 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9055 * regex.c: Likewise for stddef.h, string.h.
9056 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9057 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9058 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9059 (STDC_HEADERS): Remove obsolete defines.
9060 * sysdep.c: Include limits.h unconditionally.
9062 Assume support for memcmp, memcpy, memmove, memset.
9063 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9064 * regex.c (memcmp, memcpy):
9065 Remove; we assume C89 now.
9067 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9068 (__malloc_safe_bcopy): Remove; no longer needed.
9070 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9071 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9072 well either way, and we prefer signed to unsigned.
9074 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9076 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9077 closes the connection while we're reading (bug#9182).
9079 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9081 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9082 are specified (Bug#9168).
9084 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9086 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9087 Found by GCC static checking and --with-wide-int on a 32-bit host.
9089 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9091 * xdisp.c (compute_display_string_pos): Fix logic of caching
9092 previous display string position. Initialize cached_prev_pos to
9093 -1. Fixes slow-down at the beginning of a buffer.
9095 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9097 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9098 for attrs[LFACE_FONTSET_INDEX].
9100 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9102 * xml.c (parse_region): Remove unused local
9103 that was recently introduced.
9105 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9107 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in

9110 * xdisp.c (move_it_in_display_line_to): Record the best matching
9111 position for TO_CHARPOS while scanning the line, and restore it on
9112 exit if none of the characters scanned was an exact match.
9113 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9114 when exact match is impossible due to invisible text, and the
9115 lines are truncated.
9117 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9119 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9122 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9124 Fix a significant slow-down of cursor motion with C-n, C-p,
9125 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9126 auto-repeat under bidi redisplay in fontified buffers.
9127 * xdisp.c (compute_stop_pos_backwards): New function.
9128 (next_element_from_buffer): Call compute_stop_pos_backwards to
9129 find a suitable prev_stop when we find ourselves before
9131 (reseat): Don't look for prev_stop, as that could mean a very long
9133 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9134 <cached_disp_overlay_modiff>: Cache for last found display string
9136 (compute_display_string_pos): Return the cached position if asked
9137 about the same buffer in the same area of character positions, and
9138 the buffer wasn't changed since the time the display string
9139 position was cached.
9141 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9143 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9144 is an integer, which is important for empty lines. (Bug#9149)
9146 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9148 * frame.c (Fmodify_frame_parameters): In tty case, update the
9149 default face if necessary (Bug#4238).
9151 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9153 * editfns.c (Fstring_to_char): No need to explain what a character
9154 is in the docstring (Bug#6576).
9156 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9158 * xml.c (parse_region): Make sure we always return a tree.
9160 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9162 * xml.c (parse_region): If a document contains only comments,
9165 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9167 * xml.c (make_dom): Return comments, too.

9172 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9173 and the surrounding thread.
9174 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9175 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9176 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9178 * s/openbsd.h (BROKEN_SIGIO): Define.
9179 * unexelf.c (unexec) [__OpenBSD__]:
9180 Don't update the .mdebug section of the Alpha COFF symbol table.
9182 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9184 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9187 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>

9190 This fixes some race conditions on the permissions of any newly
9193 * alloc.c (valid_pointer_p): Use pipe, not open.
9194 This fixes some permissions issues when debugging.
9196 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9197 If fchown fails to set both uid and gid, try to set just gid,
9198 as that is sometimes allowed. Adjust the file's mode to eliminate
9199 setuid or setgid bits that are inappropriate if fchown fails.
9201 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9203 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9204 to compare Lisp_Objects.
9205 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to

9215 symbol character follows.
9217 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9219 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9220 This works around a problem with the previous change to Fcopy_file.
9221 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9222 and without this change, GCC might complain about discarding
9223 fchown's return value.
9225 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9227 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9229 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9231 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9233 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9235 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9236 it's used from the C level.
9238 * process.c: Use the same condition for POLL_FOR_INPUT in both
9239 keyboard.c and process.c (bug#1858).
9241 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9248 * doc.c (Fsubstitute_command_keys): Revert last change.
9250 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9252 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9253 quotes the next character, and doesn't affect other longer
9254 sequences (bug#8935).
9256 * lread.c (syms_of_lread): Clarify that is isn't only
9257 `eval-buffer' and `eval-defun' that's affected by
9258 `lexical-binding' (bug#8460).

9267 Fix minor problems found by static checking.
9268 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9269 (elsz): Now a signed constant, not a size_t var. We prefer signed
9270 types to unsigned, to avoid integer comparison confusion. Without
9271 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9272 "cannot optimize loop, the loop counter may overflow", a symptom
9274 * indent.c (Fvertical_motion): Mark locals as initialized.
9275 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9277 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9279 * search.c (Fre_search_backward): Mention `case-fold-search' in
9280 all the re_search_* functions (bug#8138).

9300 buffer position was specified. Initialize paragraph_embedding to
9302 (reseat_to_string): Initialize the bidi iterator.
9303 (display_string): If we need to ignore text properties of
9304 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9305 original value of -1 will not work with bidi.)

9309 (compute_display_string_end): Support display properties on Lisp
9311 (init_iterator, reseat_1, reseat_to_string): Initialize the
9312 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9313 when iterating on a string not from display properties).
9314 (compute_display_string_pos, compute_display_string_end):
9315 Fix calculation of the object to scan. Fixes an error when using
9317 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9318 base_level_stop; instead, set base_level_stop to BEGV.
9319 Fixes crashes in vertical-motion.
9320 (next_element_from_buffer): Improve commentary for when
9321 the iterator is before prev_stop.
9322 (init_iterator): Initialize bidi_p from the default value of
9323 bidi-display-reordering, not from buffer-local value. Use the
9324 buffer-local value only if initializing for buffer iteration.
9325 (handle_invisible_prop): Support invisible properties on strings
9326 that are being bidi-reordered.
9327 (set_iterator_to_next): Support bidi reordering of C strings and

9345 parts of next_element_from_buffer, next_element_from_string, and
9346 next_element_from_c_string.
9347 (tool_bar_lines_needed, redisplay_tool_bar)
9348 (display_menu_bar): Force left-to-right direction. Add a FIXME

9363 pushed the iterator stack, restore the internal state of the bidi
9364 iterator by calling bidi_pop_it same number of times.
9365 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9366 and we are bidi-iterating, don't decrement the iterator position;
9367 instead, set the first_elt flag in the bidi iterator, to produce
9369 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9370 (push_display_prop): xassert that we are iterating a buffer.

9403 (back_to_previous_visible_line_start, reseat_1)
9404 (init_iterator): Empty the bidi cache "stack".
9405 (move_it_in_display_line_to): If iterator ended up at

9431 changed. Support iteration over a string. Support strings with
9432 display properties. Support unibyte strings. Fix the type of

9532 The old code sometimes used this field without initializing it.
9534 * alloc.c (gc_sweep): Don't read past end of array.

9540 * character.c (Fcharacterp): Don't advertise optional ignored
9541 argument. (Bug#4026)

9840 Random fixes. E.g., (random) never returned negative values.
9841 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9842 subseconds part to the entropy, as that's a bit more random.
9843 Prefer signed to unsigned, since the signedness doesn't matter and
9844 in general we prefer signed. When given a limit, use a
9845 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9846 latter isn't right if USE_2_TAGS_FOR_INTS.
9847 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9848 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9861 This is more efficient than Ffile_directory_p and avoids a minor race.
9863 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9865 * buffer.c (Foverlay_put): Say what the return value is
9868 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9871 (barf_or_query_if_file_exists): Make the "File is a directory"
9872 error be more correct.
9874 * fns.c (Frequire): Remove the mention of the .gz files, since
9875 that's installation-specific, but keep the mention of
9876 `get-load-suffixes'.
9878 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9880 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9891 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9993 * eval.c (struct backtrace): Simplify and port the data structure.
9994 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9995 signed bit field, as this assumption is not portable and it makes
9996 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9997 "char debug_on_exit : 1" as this is not portable either; instead,
9998 use the portable "unsigned int debug_on_exit : 1". Remove unused
9999 member evalargs. Remove obsolete comments about cc bombing out.

10165 Integer and buffer overflow fixes (Bug#8873).
10167 * print.c (printchar, strout): Check for string overflow.
10168 (PRINTPREPARE, printchar, strout):
10169 Don't set size unless allocation succeeds.
10171 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10172 for sizes. Check for string overflow more accurately.
10173 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10175 * macros.c: Integer and buffer overflow fixes.
10176 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10177 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10181 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10183 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10185 * lread.c: Integer overflow fixes.
10186 (read_integer): Radix is now EMACS_INT, not int,
10187 to improve quality of diagnostics for out-of-range radices.
10188 Calculate buffer size correctly for out-of-range radices.
10189 (read1): Check for integer overflow in radices, and in
10190 read-circle numbers.
10191 (read_escape): Avoid int overflow.
10192 (Fload, openp, read_buffer_size, read1)
10193 (substitute_object_recurse, read_vector, read_list, map_obarray):

10209 2011-06-22 Leo Liu <sdl.web@gmail.com>
10211 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10212 Move to minibuffer.el.
10214 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10216 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10217 The following patches are for when GLYPH_DEBUG && !XASSERT.
10218 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10219 * dispnew.c (flush_stdout):
10220 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10221 Mark as externally visible.
10222 * dispnew.c (check_window_matrix_pointers): Now static.
10223 * dispnew.c (window_to_frame_vpos):
10224 * xfns.c (unwind_create_frame):
10225 * xterm.c (x_check_font): Remove unused local.
10226 * scroll.c (CHECK_BOUNDS):
10227 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10228 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10229 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10230 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10231 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10233 (debug_method_add): Use va_list and vsprintf rather than relying
10234 on undefined behavior with wrong number of arguments.
10235 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10236 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10237 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10238 since we're not interested in debugging glyphs with old libraries.
10239 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10240 GCC 4.6.0's static checking.
10242 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10244 Integer overflow and signedness fixes (Bug#8873).

10260 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10261 (.bitmaps_last, struct x_output.icon_bitmap):
10262 Use ptrdiff_t, not int, for bitmap indexes.
10263 (x_allocate_bitmap_record): Check for size overflow.
10264 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10266 Use ptrdiff_t, not int, for overlay counts.
10267 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10268 * editfns.c (overlays_around, get_pos_property):
10269 * textprop.c (get_char_property_and_overlay):
10270 * xdisp.c (next_overlay_change, note_mouse_highlight):
10271 * xfaces.c (face_at_buffer_position):
10272 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10273 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10274 (Fnext_overlay_change, Fprevious_overlay_change)
10275 (mouse_face_overlay_overlaps, Foverlays_in):
10276 Use ptrdiff_t, not int, for sizes.
10277 (overlays_at, overlays_in): Check for size-calculation overflow.
10279 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10281 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10282 (x_session_initialize): Do not assume string length fits in int.
10284 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10285 This is unlikely, but can occur if DPI is outlandish.
10287 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10288 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10290 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10291 * xrdb.c (magic_file_p, search_magic_path):
10292 Omit last arg SUFFIX; it was always 0. All callers changed.
10293 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10295 * xfont.c (xfont_match): Avoid need for strlen.
10297 * xfns.c: Don't assume strlen fits in int.

10300 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10301 not unsigned long, as we prefer signed integers. All callers changed.
10302 Detect integer overflow in repeat count.
10303 (message_dolog): Don't assume print length fits in 39 bytes.
10304 (display_mode_element): Don't assume strlen fits in int.
10306 * termcap.c: Don't assume sizes fit in int and never overflow.
10307 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10308 (gobble_line): Check for size-calculation overflow.
10310 * minibuf.c (Fread_buffer):
10311 * lread.c (intern, intern_c_string):
10312 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

10325 * filelock.c: Fix some buffer overrun and integer overflow issues.
10326 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10327 Reformulate so as not to need the command string.
10328 Invoke gzip -cd rather than gunzip, as it's more portable.
10329 (lock_info_type, lock_file_1, lock_file):
10330 Don't assume pid_t and time_t fit in unsigned long.
10331 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10332 (current_lock_owner): Prefer signed type for sizes.
10333 Use memcpy, not strncpy, where memcpy is what is really wanted.
10334 Don't assume (via atoi) that time_t and pid_t fit in int.
10335 Check for time_t and/or pid_t out of range, e.g., via a network share.
10336 Don't alloca where an auto var works fine.
10338 * fileio.c: Fix some integer overflow issues.
10339 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10340 Don't assume string length fits in int.
10341 (directory_file_name): Don't assume string length fits in long.
10342 (make_temp_name): Don't assume pid fits in int, or that its print
10343 length is less than 20.
10345 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10347 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10349 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

10355 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10356 (main): Don't invoke strlen when not needed.

10362 (Fgetenv_internal):
10363 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10365 * lread.c (invalid_syntax): Omit length argument.
10366 All uses changed. This doesn't fix a bug, but it simplifies the
10367 code away from its former Hollerith-constant appearance, and it's
10368 one less 'int' to worry about when looking at integer-overflow issues.
10369 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10371 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10372 This didn't break anything, but it didn't help either.
10373 It's confusing to put a bogus integer in a place where the actual
10374 value does not matter.
10375 (LIST_END_P): Remove unused macro and its bogus comment.
10376 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10378 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10379 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10381 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10382 We prefer signed types, and the value cannot exceed the EMACS_INT
10383 range anyway (because otherwise the length would not be representable).
10384 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10385 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10386 This avoids a GCC warning when WIDE_EMACS_INT.
10388 * indent.c (sane_tab_width): New function.
10389 (current_column, scan_for_column, Findent_to, position_indentation)
10390 (compute_motion): Use it. This is just for clarity.
10391 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10393 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10395 * lisp.h (lint_assume): New macro.
10396 * composite.c (composition_gstring_put_cache):
10397 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10399 * editfns.c, insdel.c:
10400 Omit unnecessary forward decls, to simplify future changes.
10402 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10404 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10406 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10407 Use much-faster test for byte-length change.
10408 Don't assume string byte-length fits in 'int'.
10409 Check that character arg fits in 'int'.
10410 (mapcar1): Declare byte as byte, for clarity.
10412 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10414 * fns.c (concat): Catch string overflow earlier.
10415 Do not rely on integer wraparound.
10417 * dispextern.h (struct it.overlay_strings_charpos)
10418 (struct it.selective): Now EMACS_INT, not int.
10419 * xdisp.c (forward_to_next_line_start)
10420 (back_to_previous_visible_line_start)
10421 (reseat_at_next_visible_line_start, next_element_from_buffer):
10422 Don't arbitrarily truncate the value of 'selective' to int.
10424 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10426 * composite.c: Don't truncate sizes to 'int'.
10427 (composition_gstring_p, composition_reseat_it)
10428 (composition_adjust_point): Use EMACS_INT, not int.
10429 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10430 not EMACS_UINT, for indexes.
10432 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10434 * buffer.c: Include <verify.h>.
10435 (struct sortvec.priority, struct sortstr.priority):
10436 Now EMACS_INT, not int.
10437 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10438 (struct sortstr.size, record_overlay_string)
10439 (struct sortstrlist.size, struct sortlist.used):
10440 Don't truncate size to int.
10441 (record_overlay_string): Check for size-calculation overflow.
10442 (init_buffer_once): Check at compile-time, not run-time.
10444 2011-06-22 Jim Meyering <meyering@redhat.com>
10446 Don't leak an XBM-image-sized buffer
10447 * image.c (xbm_load): Free the image buffer after using it.
10449 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10452 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10453 that Sun C diagnosed.
10454 * fns.c (secure_hash): Fix pointer signedness issue.
10455 * intervals.c (static_offset_intervals): New function.
10456 (offset_intervals): Use it.
10458 2011-06-21 Leo Liu <sdl.web@gmail.com>
10461 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10464 * fns.c (secure_hash): Rename from crypto_hash_function and change
10465 the first arg to accept symbols.
10466 (Fsecure_hash): New primitive.
10467 (syms_of_fns): New symbols.
10469 2011-06-20 Deniz Dogan <deniz@dogan.se>
10471 * process.c (Fset_process_buffer): Clarify return value in
10474 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10476 * dispnew.c (add_window_display_history): Use BVAR.
10478 * xdisp.c (debug_method_add): Use BVAR.
10479 (check_window_end, dump_glyph_matrix, dump_glyph)
10480 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10482 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10485 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10486 check till after the cache is created in init_frame_faces.
10488 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10490 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10492 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10494 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10495 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10496 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10498 Improve buffer-overflow checking (Bug#8873).
10499 * fileio.c (Finsert_file_contents):
10500 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10501 Remove the old (too-loose) buffer overflow checks.
10502 They weren't needed, since make_gap checks for buffer overflow.
10503 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10504 The old code merely checked for Emacs fixnum overflow, and relied
10505 on undefined (wraparound) behavior. The new code avoids undefined
10506 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10508 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10509 Tune. Don't use wider integers than needed. Don't use alloca.
10510 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10512 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10514 * insdel.c, lisp.h (buffer_overflow): New function.
10515 (insert_from_buffer_1, replace_range, replace_range_2):
10516 * insdel.c (make_gap_larger):
10517 * editfns.c (Finsert_char):
10518 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10520 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10522 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10524 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10526 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10527 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10529 * fileio.c: Don't assume EMACS_INT fits in off_t.
10530 (emacs_lseek): New static function.
10531 (Finsert_file_contents, Fwrite_region): Use it.
10532 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10534 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10536 * fns.c: Don't overflow int when computing a list length.
10537 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10538 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10539 truncation on 64-bit hosts. Check for QUIT every
10540 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10541 faster and is responsive enough.
10542 (Flength): Report an error instead of overflowing an integer.
10543 (Fsafe_length): Return a float if the value is not representable
10544 as a fixnum. This shouldn't happen except in contrived situations.
10545 (Fnthcdr, Fsort): Don't assume list length fits in int.
10546 (Fcopy_sequence): Don't assume vector length fits in int.
10548 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10549 (header_size, word_size): New constants.
10550 (allocate_vectorlike): Don't check size overflow here.
10551 (allocate_vector): Check it here instead, since this is the only
10552 caller of allocate_vectorlike that could cause overflow.
10553 Check that the new vector's length is representable as a fixnum.
10555 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10556 The previous code was bogus. For example, next_almost_prime (32)
10557 returned 39, which is undesirable as it is a multiple of 3; and
10558 next_almost_prime (24) returned 25, which is a multiple of 5 so
10559 why was the code bothering to check for multiples of 7?
10561 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10563 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10565 Variadic C functions now count arguments with ptrdiff_t.
10566 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10567 Back then I didn't know that the Emacs coding style prefers signed int.
10568 Also, in the meantime I found a few more instances where arguments
10569 were being counted with int, which may truncate counts on 64-bit
10570 machines, or EMACS_INT, which may be unnecessarily wide.
10571 * lisp.h (struct Lisp_Subr.function.aMANY)
10572 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10573 Arg counts are now ptrdiff_t, not size_t.
10574 All variadic functions and their callers changed accordingly.
10575 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10576 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10577 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10578 * callint.c (Fcall_interactively): Check arg count for overflow,
10579 to avoid potential buffer overrun. Use signed char, not 'int',
10580 for 'varies' array, so that we needn't bother to check its size
10581 calculation for overflow.
10582 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10583 * eval.c (apply_lambda):
10584 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10585 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10586 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10588 * callint.c (Fcall_interactively): Don't use index var as event count.
10590 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10591 * mem-limits.h (SIZE): Remove; no longer used.
10593 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10595 Remove unnecessary casts.
10596 * xterm.c (x_term_init):
10597 * xfns.c (x_set_border_pixel):
10598 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10599 These aren't needed now that we assume ANSI C.
10601 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10602 It's more likely to cause problems (due to unsigned overflow)
10605 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10607 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10609 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10611 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10613 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10615 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10617 GLYPH_CODE_FACE returns EMACS_INT, not int.
10618 * dispextern.h (merge_faces):
10619 * xfaces.c (merge_faces):
10620 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10621 Don't assume EMACS_INT fits in int.
10623 * character.h (CHAR_VALID_P): Remove unused parameter.
10624 * fontset.c, lisp.h, xdisp.c: All uses changed.
10626 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10628 * fns.c (concat): Minor tuning based on overflow analysis.
10629 This doesn't fix any bugs. Use int to hold character, instead
10630 of constantly refetching from Emacs object. Use XFASTINT, not
10631 XINT, for value known to be a character. Don't bother comparing
10632 a single byte to 0400, as it's always less.
10634 * floatfns.c (Fexpt):
10635 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10637 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10640 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10642 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10643 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10644 incorrectly succeed when S was a string, because 4294967386 was
10645 truncated before it was used.
10647 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10648 Otherwise, an out-of-range integer could cause undefined behavior
10651 * composite.c: Use int, not EMACS_INT, for characters.
10652 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10653 EMACS_INT, for values that are known to be in character range.
10654 This doesn't fix any bugs but is the usual style inside Emacs and
10655 may generate better code on 32-bit machines.
10657 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10658 This is for reasons similar to the recent CHAR_STRING fix.
10659 * charset.c (Fencode_char): Check that character arg is actually
10660 a character. Pass an int to ENCODE_CHAR.
10661 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10662 wider than 'int', as a compile-time check to prevent future regressions
10665 * character.c (char_string): Remove unnecessary casts.
10667 Make sure a 64-bit char is never passed to CHAR_STRING.
10668 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10669 by silently ignoring the top 32 bits, allowing some values
10670 that were far too large to be valid characters.
10671 * character.h: Include <verify.h>.
10672 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10673 arguments are no wider than unsigned, as a compile-time check
10674 to prevent future regressions in this area.
10676 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10677 (Fsubst_char_in_region):
10679 * xdisp.c (decode_mode_spec_coding):
10680 Adjust to CHAR_STRING's new requirement.
10681 * editfns.c (Finsert_char, Fsubst_char_in_region):
10682 * fns.c (concat): Check that character args are actually
10683 characters. Without this test, these functions did the wrong
10684 thing with wildly out-of-range values on 64-bit hosts.
10686 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10687 These casts should not be needed on 32-bit hosts, either.
10688 * keyboard.c (read_char):
10689 * lread.c (Fload): Remove casts to unsigned.
10691 * lisp.h (UNSIGNED_CMP): New macro.
10692 This fixes comparison bugs on 64-bit hosts.
10693 (ASCII_CHAR_P): Use it.
10694 * casefiddle.c (casify_object):
10695 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10696 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10697 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10698 * dispextern.h (FACE_FROM_ID):
10699 * keyboard.c (read_char): Use UNSIGNED_CMP.
10701 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10702 not to EMACS_INT, to avoid GCC warning.
10704 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10706 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10707 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10708 isn't needed on 32-bit machines.
10710 * buffer.c (Fgenerate_new_buffer_name):
10711 Use EMACS_INT for count, not int.
10712 (advance_to_char_boundary): Return EMACS_INT, not int.
10714 * data.c (Qcompiled_function): Now static.
10716 * window.c (window_body_lines): Now static.
10718 * image.c (gif_load): Rename local to avoid shadowing.
10720 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10721 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10722 * alloc.c (make_save_value): Integer argument is now of type
10723 ptrdiff_t, not int.
10724 (mark_object): Use ptrdiff_t, not int.
10725 * lisp.h (pD): New macro.
10726 * print.c (print_object): Use it.
10728 * alloc.c: Use EMACS_INT, not int, to count objects.
10729 (total_conses, total_markers, total_symbols, total_vector_size)
10730 (total_free_conses, total_free_markers, total_free_symbols)
10731 (total_free_floats, total_floats, total_free_intervals)
10732 (total_intervals, total_strings, total_free_strings):
10733 Now EMACS_INT, not int. All uses changed.
10734 (Fgarbage_collect): Compute overall total using a double, so that
10735 integer overflow is less likely to be a problem. Check for overflow
10736 when converting back to an integer.
10737 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10738 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10739 These were 'int' variables that could overflow on 64-bit hosts;
10740 they were never used, so remove them instead of repairing them.
10741 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10742 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10743 Previously, this ceilinged at INT_MAX, but that doesn't work on
10745 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10747 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10748 (allocate_vectorlike): Check for ptrdiff_t overflow.
10749 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10750 when a (possibly-narrower) signed value would do just as well.
10751 We prefer using signed arithmetic, to avoid comparison confusion.
10753 * alloc.c: Catch some string size overflows that we were missing.
10754 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10755 for convenience in STRING_BYTES_MAX.
10756 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10757 The definition here is exact; the one in lisp.h was approximate.
10758 (allocate_string_data): Check for string overflow. This catches
10759 some instances we weren't catching before. Also, it catches
10760 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10761 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10762 and ptrdiff_t and EMACS_INT are both 64 bits.
10764 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10765 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10766 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10768 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10770 * alloc.c (Fmake_string): Check for out-of-range init.
10772 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10774 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10776 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10778 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10779 xg_get_default_scrollbar_width.
10781 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10782 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10783 (style_changed_cb): Call update_theme_scrollbar_width and call
10784 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10785 all frames (Bug#8505).
10786 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10787 Call gtk_window_set_resizable if HAVE_GTK3.
10788 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10789 and height if HAVE_GTK3 (Bug#8505).
10790 (scroll_bar_width_for_theme): New variable.
10791 (update_theme_scrollbar_width): New function.
10792 (xg_get_default_scrollbar_width): Move code to
10793 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10794 (xg_initialize): Call update_theme_scrollbar_width.
10796 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10798 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10800 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10802 * frame.c (make_frame): Call other_buffer_safely instead of
10805 * window.c (temp_output_buffer_show): Call display_buffer with
10806 second argument Vtemp_buffer_show_specifiers and reset latter
10807 immediately after the call.
10808 (Vtemp_buffer_show_specifiers): New variable.
10809 (auto_window_vscroll_p, next_screen_context_lines)
10810 (Vscroll_preserve_screen_position): Remove leading asterisks from
10813 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10815 Fix minor problems found by GCC 4.6.0 static checking.
10816 * buffer.c (Qclone_number): Remove for now, as it's unused.
10817 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10818 (record_buffer): Remove unused local.
10819 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10820 (set_frame_buffer_list): Remove; unused.
10821 * frame.h (other_visible_frames): Remove decl.
10822 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10823 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10824 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10826 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10827 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10828 Define only if HAVE_GPM.
10829 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10830 (update_hints_inhibit): Remove; never set. All uses removed.
10831 * widgetprv.h (emacsFrameClassRec): Remove decl.
10832 * window.c (delete_deletable_window): Now returns void, since it
10833 wasn't returning anything.
10834 (compare_window_configurations): Remove unused locals.
10835 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10836 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10837 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10838 the same widths as pointers. This follows up on the 2011-05-06 patch.
10839 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10840 * xterm.h: Likewise.
10841 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10843 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
10845 * makefile.w32-in: Update dependencies.
10846 (LISP_H): Add lib/intprops.h.
10848 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10850 * image.c (gif_load): Add animation frame delay to the metadata.
10851 (syms_of_image): Use DEFSYM. New symbol `delay'.
10853 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10855 * window.c (delete_deletable_window): Re-add.
10856 (Fset_window_configuration): Rewrite to handle dead buffers and
10857 consequently deletable windows.
10858 (window_tree, Fwindow_tree): Remove. Supply functionality in
10860 (compare_window_configurations): Simplify code.
10862 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10864 * image.c (imagemagick_load_image): Fix type mismatch.
10865 (Fimagemagick_types): Likewise.
10867 * window.h (replace_buffer_in_windows): Declare.
10869 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10871 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10872 Qclone_number. Remove external declaration of Qdelete_window.
10873 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10875 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10876 Run Qbuffer_list_update_hook if allowed.
10877 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10878 buffer list implementation.
10879 (other_buffer_safely): New function.
10880 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10881 calls to replace_buffer_in_windows and
10882 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10884 (record_buffer): Inhibit quitting and rewrite using quittable
10885 functions. Run Qbuffer_list_update_hook if allowed.
10886 (Frecord_buffer, Funrecord_buffer): New functions.
10887 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10888 Move switch-to-buffer to window.el.
10889 (bury-buffer): Move to window.el.
10890 (Vbuffer_list_update_hook): New variable.
10892 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10895 * window.h (resize_frame_windows): Move up in code.
10896 (Fwindow_frame): Remove EXFUN.
10897 (replace_buffer_in_all_windows): Remove prototype.
10898 (replace_buffer_in_windows_safely): Add prototype.
10900 * window.c: Declare Qdelete_window static again. Move down
10901 declaration of select_count.
10902 (Fnext_window, Fprevious_window): Rewrite doc-strings.

11350 (bidi_resolve_explicit, bidi_resolve_weak)
11351 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
11352 bidi_it->nchars is non-positive.
11353 (bidi_level_of_next_char): Don't try to lookup the cache for the
11354 next/previous character if nothing is cached there yet, or if we
11355 were just reseat()'ed to a new position.
11357 * xdisp.c (set_cursor_from_row): Set start and stop points
11358 according to the row's direction when priming the loop that looks
11359 for the glyph on which to display cursor.
11360 (single_display_spec_intangible_p): Function deleted.
11361 (display_prop_intangible_p): Reimplement to call
11362 handle_display_spec instead of single_display_spec_intangible_p.
11363 Accept 3 additional arguments needed by handle_display_spec.
11364 This fixes incorrect cursor motion across display property with complex
11365 values: lists, `(when COND...)' forms, etc.
11366 (single_display_spec_string_p): Support property values that are
11367 lists with the argument STRING its top-level element.
11368 (display_prop_string_p): Fix the condition for processing a
11369 property that is a list to be consistent with handle_display_spec.
11370 (handle_display_spec): New function, refactored from the
11371 last portion of handle_display_prop.
11372 (compute_display_string_pos): Accept additional argument
11373 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11374 value of a `display' property is a "replacing spec".
11375 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11376 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11377 the display property, but just return a value indicating whether
11378 the display property will replace the characters it covers.
11379 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11380 frame_window_p members of struct bidi_it.
11381 (compute_display_string_pos, compute_display_string_end):
11383 (push_it): Accept second argument POSITION, where pop_it should
11384 jump to continue iteration.
11385 (reseat_1): Initialize bidi_it.disp_pos.
11387 * keyboard.c (adjust_point_for_property): Adjust the call to
11388 display_prop_intangible_p to its new signature.
11390 * dispextern.h (struct bidi_it): New member frame_window_p.
11391 (bidi_init_it): Update prototypes.
11392 (display_prop_intangible_p): Update prototype.
11393 (compute_display_string_pos, compute_display_string_end):
11394 Declare prototypes.

11400 Malloc failure behavior now depends on size of allocation.
11401 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11402 * lisp.h: Change signatures accordingly.
11403 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11404 All callers changed. (Bug#8762)
11406 * gnutls.c: Use Emacs's memory allocators.
11407 Without this change, the gnutls library would invoke malloc etc.
11408 directly, which causes problems on non-SYNC_INPUT hosts, and which
11409 runs afoul of improving memory_full behavior. (Bug#8761)
11410 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11411 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11412 xfree instead of the default malloc, realloc, free.
11413 (Fgnutls_boot): No need to check for memory allocation failure,
11414 since xmalloc does that for us.
11416 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11417 * category.c (hash_get_category_set):
11418 * ccl.c (ccl_driver):

11430 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11431 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11432 * image.c (make_image, search_image_cache, lookup_image)
11433 (xpm_put_color_table_h):
11434 * lisp.h (struct Lisp_Hash_Table):
11435 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11436 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11437 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11438 * alloc.c (allocate_vectorlike):
11439 Check for overflow in vector size calculations.
11440 * ccl.c (ccl_driver):
11441 Check for overflow when converting EMACS_INT to int.
11442 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11443 need to be updated by these changes.
11444 * fns.c (make_hash_table, maybe_resize_hash_table):
11445 Check for integer overflow with large hash tables.
11446 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11447 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11448 (SXHASH_REDUCE): New macro.
11449 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11450 Use it instead of discarding useful hash info with large hash values.
11451 (sxhash_float): New function.
11452 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11453 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11454 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11455 Rewrite to use FIXNUM_BITS, as this simplifies things.
11456 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11457 Adjust signatures to match updated version of code.
11458 (consing_since_gc): Now EMACS_INT, since a single hash table can
11459 use more than INT_MAX bytes.
11461 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11463 Make it possible to build with GCC-4.6+ -O2 -flto.
11465 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11467 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11469 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11470 Call minibuffer-inactive-mode.
11472 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11474 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11475 Update dependencies.
11477 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11479 * data.c (init_data): Remove code for UTS, this system is not
11482 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11484 Don't force ./temacs to start in terminal mode.
11486 * frame.c (make_initial_frame): Initialize faces in all cases, not
11487 only when CANNOT_DUMP is defined.
11488 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11490 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11492 * dispnew.c (add_window_display_history): Use const for the string
11493 pointer. Remove declaration, not needed.
11495 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11497 Use 'inline', not 'INLINE'.
11498 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11499 * alloc.c, fontset.c (INLINE): Remove.
11500 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11501 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11502 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11503 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11504 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11506 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11508 Make it possible to run ./temacs.
11510 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11511 syms_of_callproc does the same thing. Remove test for
11512 "initialized", do it in the caller.
11513 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11515 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11517 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11518 (read_minibuf): Use get_minibuffer.
11519 (syms_of_minibuf): Use DEFSYM.
11520 (Qmetadata): New var.
11521 * data.c (Qbuffer): Don't make it static.
11522 (syms_of_data): Use DEFSYM.
11524 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11526 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11527 (CCL_CODE_MIN): New macro.
11529 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11531 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11533 * eval.c (Qdebug): Now static.
11534 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11535 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11536 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11538 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11540 * image.c: Various fixes to ImageMagick code comments.
11541 (Fimagemagick_types): Doc fix.
11543 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11545 Minor fixes prompted by GCC 4.6.0 warnings.
11547 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11549 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11550 (x_clipboard_manager_save_all): Move extern decl to ...
11551 * xterm.h: ... here, so that it can be checked for consistency.
11553 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11555 * xselect.c (x_clipboard_manager_save_frame)
11556 (x_clipboard_manager_save_all): New functions.
11557 (Fx_clipboard_manager_save): Lisp function deleted.
11559 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11560 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11562 * xterm.h: Update prototype.
11564 2011-05-28 William Xu <william.xwl@gmail.com>
11566 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11567 exiting (Bug#8239).
11569 2011-05-28 Jim Meyering <meyering@redhat.com>
11571 Avoid a sign-extension bug in crypto_hash_function.
11572 * fns.c (to_uchar): Define.
11573 (crypto_hash_function): Use it to convert some newly-signed
11574 variables to unsigned, to avoid sign-extension bugs. For example,
11575 without this change, (md5 "truc") would evaluate to
11576 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11577 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11578 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11580 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11582 Integer overflow fixes.
11584 * dbusbind.c: Serial number integer overflow fixes.
11585 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11586 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11587 to hold a serial number that is too large for a fixnum.
11588 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11589 Check for serial numbers out of range. Decode any serial number
11590 that was so large that it became a float. (Bug#8722)
11592 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11593 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11594 Use XFASTINT rather than XUINT when numbers are nonnegative.
11595 (xd_append_arg, Fdbus_method_return_internal):
11596 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11597 arguments, check that Lisp number is nonnegative, rather than
11598 silently wrapping negative numbers around. (Bug#8722)
11599 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11602 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11604 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11606 ccl: Add integer overflow checks.
11607 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11608 (IN_INT_RANGE): New macros.
11609 (ccl_driver): Use them to check for integer overflow when
11610 decoding a CCL program. Many of the new checks are whether XINT (x)
11611 fits in int; it doesn't always, on 64-bit hosts. The new version
11612 doesn't catch all possible integer overflows, but it's an
11613 improvement. (Bug#8719)
11615 * alloc.c (make_event_array): Use XINT, not XUINT.
11616 There's no need for unsigned here.
11618 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11619 This follows up to the 2011-05-06 change that substituted uintptr_t
11620 for EMACS_INT. This case wasn't caught back then.
11622 Rework Fformat to avoid integer overflow issues.
11623 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11624 now (part of C89). Include <verify.h>.
11625 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11626 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11627 (Fformat): Avoid the prepass trying to compute sizes; it was only
11628 approximate and thus did not catch overflow reliably. Instead, walk
11629 through the format just once, formatting and computing sizes as we go,
11630 checking for integer overflow at every step, and allocating a larger
11631 buffer as needed. Keep track separately whether the format is
11632 multibyte. Keep only the most-recently calculated precision, rather
11633 than them all. Record whether each argument has been converted to
11634 string. Use EMACS_INT, not int, for byte and char and arg counts.
11635 Support field widths and precisions larger than INT_MAX. Avoid
11636 sprintf's undefined behavior with conversion specifications such as %#d
11637 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11638 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11639 formatting out-of-range floating point numbers with int
11640 formats. (Bug#8668)
11642 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11644 * data.c: Avoid integer truncation in expressions involving floats.
11645 * data.c: Include <intprops.h>.
11646 (arith_driver): When there's an integer overflow in an expression
11647 involving floating point, convert the integers to floating point
11648 so that the resulting value does not suffer from catastrophic
11649 integer truncation. For example, on a 64-bit host (* 4
11650 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11651 Do not rely on undefined behavior after integer overflow.
11653 merge count_size_as_multibyte, parse_str_to_multibyte
11654 * character.c, character.h (count_size_as_multibyte):
11655 Rename from parse_str_to_multibyte; all uses changed.
11656 Check for integer overflow.
11657 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11658 since it's now a duplicate of the other. This is more of
11659 a character than a buffer op, so better that it's in character.c.
11660 * fns.c, print.c: Adjust to above changes.
11662 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11664 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11666 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11668 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11669 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11670 (x_clipboard_manager_save): Now static.
11671 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11673 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11674 (crypto_hash_function): Now static.
11675 Fix pointer signedness problems. Avoid unnecessary initializations.
11677 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11679 * termhooks.h (Vselection_alist): Make it terminal-local.
11681 * terminal.c (create_terminal): Initialize it.
11683 * xselect.c: Support for clipboard managers.
11684 (Vselection_alist): Move to termhooks.h as terminal-local var.
11685 (LOCAL_SELECTION): New macro.
11686 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11687 (symbol_to_x_atom): Remove gratuitous arg.
11688 (x_handle_selection_request, lisp_data_to_selection_data)
11689 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11690 (x_own_selection, x_get_local_selection, x_convert_selection):
11691 New arg, specifying work frame. Use terminal-local Vselection_alist.
11692 (some_frame_on_display): Delete unused function.
11693 (Fx_own_selection_internal, Fx_get_selection_internal)
11694 (Fx_disown_selection_internal, Fx_selection_owner_p)
11695 (Fx_selection_exists_p): New optional frame arg.
11696 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11697 (x_handle_selection_clear): Don't treat other terminals with the
11698 same keyboard specially. Use the terminal-local Vselection_alist.
11699 (x_clear_frame_selections): Use Frun_hook_with_args.
11701 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11703 * xterm.h: Add support for those atoms.
11705 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11707 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11708 (converted_selections, conversion_fail_tag): New global variables.
11709 (x_selection_request_lisp_error): Free the above.
11710 (x_get_local_selection): Remove unnecessary code.
11711 (x_reply_selection_request): Args changed; handle arbitrary array
11712 of converted selections stored in converted_selections.
11713 Separate the XChangeProperty and SelectionNotify steps.
11714 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11715 (x_convert_selection): New function.
11716 (x_handle_selection_event): Simplify.
11717 (x_get_foreign_selection): Don't ignore incoming requests while
11718 waiting for an answer; this will fail when we implement
11719 SAVE_TARGETS, and seems unnecessary anyway.
11720 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11721 (Vx_sent_selection_functions): Doc fix.
11723 2011-05-26 Leo Liu <sdl.web@gmail.com>
11725 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11727 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11729 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11731 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11732 for fringe update if it has periodic bitmap.
11733 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11734 and fringe_bitmap_periodic_p.
11736 * fringe.c (get_fringe_bitmap_data): New function.
11737 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11738 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11739 row. Mark glyph row for fringe update if periodicity changed.
11741 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11742 for fringe update unless it has periodic bitmap.
11744 2011-05-25 Kenichi Handa <handa@m17n.org>
11746 * xdisp.c (get_next_display_element): Set correct it->face_id for
11747 a static composition.

11760 * gnutls.c: Remove unused macros.
11761 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11762 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11763 Remove macros that are defined and never used.
11764 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11766 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11768 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11769 (Fx_get_selection_internal): Minor cleanup.
11770 (Fx_own_selection_internal): Rename arguments for consistency with
11773 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11775 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11777 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11779 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11781 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11783 * dispnew.c (scrolling_window): Don't exclude the case that the
11784 last enabled row in the desired matrix touches the bottom boundary.
11786 2011-05-21 Glenn Morris <rgm@gnu.org>
11788 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11789 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11790 and add some more files.
11792 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11794 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11795 report_file_error introduced by the change from 2011-05-07.
11797 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11799 * systime.h (Time): Define only if emacs is defined.
11800 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11801 where the include path doesn't have X11/X.h by default. See
11802 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11804 2011-05-20 Kenichi Handa <handa@m17n.org>
11806 * composite.c (find_automatic_composition): Fix previous change.
11808 2011-05-20 Glenn Morris <rgm@gnu.org>
11810 * lisp.mk: New file, split from Makefile.in.
11811 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11812 (shortlisp): Remove.
11813 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11815 2011-05-19 Glenn Morris <rgm@gnu.org>
11817 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11818 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11819 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11820 (lisp): Set the order to that of loadup.el.
11821 (shortlisp): Make it a copy of $lisp.
11822 (SOME_MACHINE_LISP): Remove.
11823 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11824 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11826 2011-05-18 Kenichi Handa <handa@m17n.org>
11828 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11829 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11830 (find_automatic_composition): Mostly rewrite for efficiency.
11832 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11834 * makefile.w32-in: Update dependencies.
11836 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11838 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11839 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11841 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11843 Fix some integer overflow issues, such as string length overflow.
11845 * insdel.c (count_size_as_multibyte): Check for string overflow.
11847 * character.c (lisp_string_width): Check for string overflow.
11848 Use EMACS_INT, not int, for string indexes and lengths; in
11849 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11850 the resulting string length overflows an EMACS_INT; instead,
11851 report a string overflow if no precision given. When checking for
11852 precision exhaustion, use a check that cannot possibly have
11853 integer overflow. (Bug#8675)
11854 * character.h (lisp_string_width): Adjust to new signature.
11856 * alloc.c (string_overflow): New function.
11857 (Fmake_string): Use it. This doesn't change behavior, but saves
11858 a few bytes and will simplify future changes.
11859 * character.c (string_escape_byte8): Likewise.
11860 * lisp.h (string_overflow): New decl.
11862 Fixups, following up to the user-interface timestamp change.
11863 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11864 for UI timestamps, instead of unsigned long.
11865 * msdos.c (mouse_get_pos): Likewise.
11866 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11867 * w32gui.h (Time): Define by including "systime.h" rather than by
11868 declaring it ourselves. (Bug#8664)
11870 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11871 * image.c (clear_image_cache): Likewise.
11873 * term.c (term_mouse_position): Don't assume time_t wraparound.
11875 Be more systematic about user-interface timestamps.
11876 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11877 and sometimes 'EMACS_UINT', to represent these timestamps.
11878 This change causes it to use 'Time' uniformly, as that's what X uses.
11879 This makes the code easier to follow, and makes it easier to catch
11880 integer overflow bugs such as Bug#8664.
11881 * frame.c (Fmouse_position, Fmouse_pixel_position):
11882 Use Time, not unsigned long, for user-interface timestamps.
11883 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11884 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11885 * keyboard.h (last_event_timestamp): Likewise.
11886 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11887 * menu.h (xmenu_show): Likewise.
11888 * term.c (term_mouse_position): Likewise.
11889 * termhooks.h (struct input_event.timestamp): Likewise.
11890 (struct terminal.mouse_position_hook): Likewise.
11891 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11892 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11893 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11894 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11895 what it was before.
11896 * menu.h, termhooks.h: Include "systime.h", for Time.
11898 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11899 Don't assume that the difference between two unsigned long values
11900 can fit into an integer. At this point, we know button_down_time
11901 <= event->timestamp, so the difference must be nonnegative, so
11902 there's no need to cast the result if double-click-time is
11903 nonnegative, as it should be; check that it's nonnegative, just in
11904 case. This bug is triggered when events are more than 2**31 ms
11905 apart (about 25 days). (Bug#8664)
11907 * xselect.c (last_event_timestamp): Remove duplicate decl.
11908 (x_own_selection): Remove needless cast to unsigned long.
11910 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11911 that always fit in int. Use a sentinel instead of a counter, to
11912 avoid a temp and to allay GCC's concerns about possible int overflow.
11913 * frame.h (struct frame): Use int for menu_bar_items_used
11914 instead of EMACS_INT, since it always fits in int.
11916 * menu.c (grow_menu_items): Check for int overflow.
11918 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11920 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11921 Before, the code was not consistent. These values cannot exceed
11922 2**31 - 1 so there's no need to make them unsigned.
11923 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11924 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11925 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11927 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11929 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11930 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11931 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11932 presumably because the widths might not match.
11934 * window.c (size_window): Avoid needless test at loop start.
11936 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11938 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11940 2011-05-12 Drew Adams <drew.adams@oracle.com>
11942 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11944 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11946 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11947 `width' to `bar_area_x' and `bar_area_width', respectively.
11948 (x_scroll_run): Take account of fringe background extension.
11950 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11951 Rename local vars `left' and `width' to `bar_area_x' and
11952 `bar_area_width', respectively.
11953 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11954 background extension.
11956 2011-05-10 Jim Meyering <meyering@redhat.com>
11958 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11960 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11962 * image.c (Finit_image_library): Return t for built-in image types,
11963 like pbm and xbm. (Bug#8640)
11965 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11967 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11969 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11971 * w32console.c (Fset_screen_color): Doc fix.
11972 (Fget_screen_color): New function.
11973 (syms_of_ntterm): Defsubr it.
11975 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11976 unlink the temporary file if Fcall_process didn't create it in the
11978 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11979 child process will be redirected to a file specified with `:file'.
11980 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11981 cue to call_process_cleanup not to close that handle.
11983 2011-05-07 Ben Key <bkey76@gmail.com>
11985 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11986 one of two shell specific rules, either bootstrap-temacs-CMD or
11987 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11988 to the previous implementation of the bootstrap-temacs rule.
11989 The bootstrap-temacs-CMD rule is similar to the previous
11990 implementation of the bootstrap-temacs rule except that it
11991 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11994 These changes, along with some changes to nt/configure.bat,
11995 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11996 earlier fix to add support for --cflags and --ldflags options
11997 that include quotes so that it works whether make uses cmd or
12000 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12002 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12003 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12005 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12006 a string. Handle both cases.
12007 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12008 (Fdbus_register_method): Use Qinvalid_function.
12010 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12012 * makefile.w32-in: Update dependencies.
12013 (LISP_H): Add inttypes.h and stdin.h.
12014 (PROCESS_H): Add unistd.h.
12016 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12018 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12019 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12021 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12023 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12025 * term.c (vfatal): Remove stray call to va_end.
12026 It's not needed and the C Standard doesn't allow it here anyway.
12028 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12029 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12031 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12034 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12036 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12038 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12040 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12042 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12044 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12045 * charset.c (Fdefine_charset_internal): Don't initialize
12046 charset.code_space[15]. The value was garbage, on hosts with
12047 32-bit int (Bug#8600).
12049 * lread.c (read_integer): Be more consistent with string-to-number.
12050 Use string_to_number to do the actual conversion; this avoids
12051 rounding errors and fixes some other screwups. Without this fix,
12052 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12053 (digit_to_number): Move earlier, for benefit of read_integer.
12054 Return -1 if the digit is out of range for the base, -2 if it is
12055 not a digit in any supported base. (Bug#8602)
12057 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12059 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12060 to match comment at start of function. This also removes a
12061 GCC warning about overflow in a 32+64-bit port.
12063 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12065 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12066 Reported by Stefan Monnier in
12067 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12068 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12069 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12071 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12072 (EMACS_UINTPTR): Likewise, with uintptr_t.
12074 * lisp.h: Prefer 64-bit EMACS_INT if available.
12075 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12076 on 32-bit hosts that have 64-bit int, so that they can access
12078 However, temporarily disable this change unless the temporary
12079 symbol WIDE_EMACS_INT is defined.
12081 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12083 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12084 This removes an assumption that EMACS_INT and long are the same
12085 width as pointers. The assumption is true for Emacs porting targets
12086 now, but we want to make other targets possible.
12087 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12088 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12089 In the rest of the code, change types of integers that hold casted
12090 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12091 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12092 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12093 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12094 No need to cast type when ORing.
12095 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12096 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12097 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12098 assume EMACS_INT is the same width as char *.
12099 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12100 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12101 Remove no-longer-needed casts.
12102 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12103 (xg_tool_bar_help_callback, xg_make_tool_item):
12104 Use EMACS_INTPTR to hold an integer
12105 that will be cast to void *; this can avoid a GCC warning
12106 if EMACS_INT is not the same width as void *.
12107 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12108 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12109 (current_message_1, set_message_1):
12110 Use a local to convert to proper width without a cast.
12111 * xmenu.c (dialog_selection_callback): Likewise.
12113 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12114 Also, don't assume VALBITS / RAND_BITS is less than 5,
12115 and don't rely on undefined behavior when shifting a 1 left into
12117 * lisp.h (get_random): Change signature to match.
12119 * lread.c (hash_string): Use size_t, not int, for hash computation.
12120 Normally we prefer signed values; but hashing is special, because
12121 it's better to use unsigned division on hash table sizes so that
12122 the remainder is nonnegative. Also, size_t is the natural width
12123 for hashing into memory. The previous code used 'int', which doesn't
12124 retain enough info to hash well into very large tables.
12125 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12127 * dbusbind.c: Don't possibly lose pointer info when converting.
12128 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12129 Use XPNTR rather than XHASH, so that the high-order bits of
12130 the pointer aren't lost when converting through void *.
12132 * eval.c (Fautoload): Don't double-shift a pointer.
12134 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12136 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12138 * gnutls.c (DEF_GNUTLS_FN):
12139 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12141 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12143 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12146 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12148 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12149 New version that can reserve upto 2GB of heap space.
12151 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12153 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12155 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12157 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12158 `gnutls_certificate_set_x509_key_file'.
12160 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12162 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12163 Update dependencies.
12165 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12167 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12168 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12169 Remove unused parameter `fildes'.
12170 * process.c (read_process_output, send_process): Don't pass it.
12172 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12174 Fix previous change: the library cache is defined in w32.c.
12175 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12176 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12178 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12180 Implement dynamic loading of GnuTLS on Windows.
12182 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12183 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12184 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12187 * gnutls.c (Qgnutls_dll): Define.
12188 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12189 (gnutls_*): Declare function pointers.
12190 (init_gnutls_functions): New function to initialize function pointers.
12191 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12192 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12193 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12194 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12195 (emacs_gnutls_write, emacs_gnutls_read)
12196 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12197 (Fgnutls_available_p): New function.

12215 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12217 * process.c: Include lisp.h before w32.h, not after.
12218 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12219 instead of gnutls_record_check_pending.
12221 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12223 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12225 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

12271 rather than `XVECTOR (FOO)->size'.
12273 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12274 inttypes.h, as a gnulib replacement is used if it not available in

12289 charbuf for the composition carryover bytes.
12291 2011-04-21 Eli Zaretskii <eliz@gnu.org>

12296 %llo or %llx format is passed. (Bug#8545)
12298 * window.c (window_scroll_line_based): Use a marker instead of
12299 simple variables to record original value of point. (Bug#7952)

12302 produced by %s or %c overflows available buffer space. (Bug#8545)
12304 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12306 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

12309 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12311 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12313 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12315 * keyboard.c (Qdelayed_warnings_hook): Define.
12316 (command_loop_1): Run `delayed-warnings-hook'
12317 if Vdelayed_warnings_list is non-nil.
12318 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12319 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12321 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12323 * doprnt.c (doprnt): Don't return value smaller than the buffer
12324 size if the message was truncated. (Bug#8545).
12326 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12328 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

12333 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12335 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12337 * makefile.w32-in: Update dependencies.
12339 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12341 Improve `doprnt' and its usage. (Bug#8545)
12342 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12343 `format_end'. Remove support for %l as a conversion specifier.
12344 Don't use xrealloc. Improve diagnostics when the %l size modifier
12345 is used. Update the commentary.
12347 * eval.c (verror): Simplify calculation of size_t.
12349 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12352 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12354 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12357 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12359 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12360 This makes this file independent of the recent pseudovector change.
12362 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12364 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12366 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12367 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12368 Remove unused local.
12369 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12371 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12372 GCC 4.6.0 optimizes based on type-based alias analysis.
12373 For example, if b is of type struct buffer * and v of type struct
12374 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12375 != &v->size, and therefore "v->size = 1; b->size = 2; return
12376 v->size;" must therefore return 1. This assumption is incorrect
12377 for Emacs, since it type-puns struct Lisp_Vector * with many other
12378 types. To fix this problem, this patch adds a new type struct
12379 vectorlike_header that documents the constraints on layout of vectors
12380 and pseudovectors, and helps optimizing compilers not get fooled
12381 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12382 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12383 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12385 (XSETPVECTYPE): Rewrite in terms of new macro.
12386 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12387 This is a bit clearer, and further avoids the possibility of
12388 undesirable aliasing.
12389 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12390 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12391 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12392 since Lisp_Subr is a special case (no "next" field).
12393 (ASIZE): Now uses header.size rather than size.
12394 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12395 to avoid the hassle of writing XVECTOR (foo)->header.size.
12396 (struct vectorlike_header): New type.
12397 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12398 object, to help avoid aliasing.
12399 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12400 (SUBRP): Likewise, since Lisp_Subr is a special case.
12401 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12402 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12403 (struct Lisp_Hash_Table): Combine first two members into a single
12404 struct vectorlike_header member. All uses of "size" and "next" members
12405 changed to be "header.size" and "header.next".
12406 * buffer.h (struct buffer): Likewise.
12407 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12408 * frame.h (struct frame): Likewise.
12409 * process.h (struct Lisp_Process): Likewise.
12410 * termhooks.h (struct terminal): Likewise.
12411 * window.c (struct save_window_data, struct saved_window): Likewise.
12412 * window.h (struct window): Likewise.
12413 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12414 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12415 * buffer.c (init_buffer_once): Likewise.
12416 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12418 * process.c (Fformat_network_address): Use local var for size,
12421 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12423 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12424 * data.c (atof): Remove decl; no longer used or needed.
12425 (digit_to_number): Move to lread.c.
12426 (Fstring_to_number): Use new string_to_number function, to be
12427 consistent with how the Lisp reader treats infinities and NaNs.
12428 Do not assume that floating-point numbers represent EMACS_INT
12429 without losing information; this is not true on most 64-bit hosts.
12430 Avoid double-rounding errors, by insisting on integers when
12431 parsing non-base-10 numbers, as the documentation specifies.
12432 * lisp.h (string_to_number): New decl, replacing ...
12433 (isfloat_string): Remove.
12434 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12435 (read1): Do not accept +. and -. as integers; this
12436 appears to have been a coding error. Similarly, do not accept
12437 strings like +-1e0 as floating point numbers. Do not report
12438 overflow for integer overflows unless the base is not 10 which
12439 means we have no simple and reliable way to continue.
12440 Break out the floating-point parsing into a new
12441 function string_to_number, so that Fstring_to_number parses
12442 floating point numbers consistently with the Lisp reader.
12443 (digit_to_number): Move here from data.c. Make it static inline.
12444 (E_CHAR, EXP_INT): Remove, replacing with ...
12445 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12446 (string_to_number): New function, replacing isfloat_string.
12447 This function checks for valid syntax and produces the resulting
12448 Lisp float number too. Rework it so that string-to-number
12449 no longer mishandles examples like "1.0e+". Use strtoumax,
12450 so that overflow for non-base-10 numbers is reported only when
12451 there's no portable and simple way to convert to floating point.
12453 * textprop.c (set_text_properties_1): Rewrite for clarity,
12454 and to avoid GCC warning about integer overflow.
12456 * intervals.h (struct interval): Use EMACS_INT for members
12457 where EMACS_UINT might cause problems. See
12458 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12459 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12460 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12462 (offset_intervals): Tell GCC not to worry about length overflow
12463 when negating a negative length.
12465 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12466 (overrun_check_free): Likewise.
12468 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12469 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12472 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12473 (gnutls_make_error): Rename local to avoid shadowing.
12474 (gnutls_emacs_global_deinit): ifdef out; not used.
12475 (Fgnutls_boot): Use const for pointer to readonly storage.
12476 Comment out unused local. Fix pointer signedness problems.
12478 * lread.c (openp): Don't stuff size_t into an 'int'.
12479 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12480 about possible signed overflow.
12482 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12483 (GDK_KEY_g): Don't define if already defined.
12484 (xg_prepare_tooltip): Avoid pointer signedness problem.
12485 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12487 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12488 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12490 * xfns.c (Fx_window_property): Simplify a bit,
12491 to make a bit faster and to avoid GCC 4.6.0 warning.
12492 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12494 * fns.c (internal_equal): Don't assume size_t fits in int.
12496 * alloc.c (compact_small_strings): Tighten assertion a little.
12498 Replace pEd with more-general pI, and fix some printf arg casts.
12499 * lisp.h (pI): New macro, generalizing old pEd macro to other
12500 conversion specifiers. For example, use "...%"pI"d..." rather
12501 than "...%"pEd"...".
12502 (pEd): Remove. All uses replaced with similar uses of pI.
12503 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12504 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12505 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12506 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12507 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12508 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12509 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12511 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12512 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12513 * print.c (safe_debug_print, print_object): Likewise.
12514 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12516 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12517 avoiding the 0 flag, which is not portable.
12518 * process.c (Fmake_network_process): Use pI to avoid cast.
12519 * region-cache.c (pp_cache): Likewise.
12520 * xdisp.c (decode_mode_spec): Likewise.
12521 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12522 behavior on 64-bit hosts with printf arg.
12523 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12524 (x_stop_queuing_selection_requests): Likewise.
12525 (x_get_window_property): Don't truncate byte count to an 'int'
12528 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12529 here, since it parses constructs like leading '-' and spaces,
12530 which are not wanted; and it overflows with large numbers.
12531 Instead, simply match F[0-9]+, which is what is wanted anyway.
12533 * alloc.c: Remove unportable assumptions about struct layout.
12534 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12535 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12536 (allocate_vectorlike, make_pure_vector): Use the new macros,
12537 plus offsetof, to remove unportable assumptions about struct layout.
12538 These assumptions hold on all porting targets that I know of, but
12539 they are not guaranteed, they're easy to remove, and removing them
12540 makes further changes easier.
12542 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12543 This doesn't fix a bug but makes the code clearer.
12544 (string_overrun_cookie): Now const. Use initializers that
12545 don't formally overflow signed char, to avoid warnings.
12546 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12547 can cause Emacs to crash when string overrun checking is enabled.
12548 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12549 multiple of sizeof (EMACS_INT); it need not be, if
12550 alignof(EMACS_INT) < sizeof (EMACS_INT).
12551 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12553 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12555 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12557 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12559 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12560 supposed to be handshaking. (Bug#8556)
12561 Reported by Paul Eggert <eggert@cs.ucla.edu>.

12565 * lisp.h (Qdebug): List symbol.
12566 * eval.c (Qdebug): Restore global linkage.
12567 * keyboard.c (debug-on-event): New variable.
12568 (handle_user_signal): Break into debugger when debug-on-event
12569 matches the current signal symbol.
12571 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12573 * alloc.c (check_sblock, check_string_bytes)
12574 (check_string_free_list): Convert to standard C.
12576 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12578 * w32.c (emacs_gnutls_push): Fix typo.
12580 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12582 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12583 "cast to pointer from integer of different size".
12585 Improve doprnt and its use in verror. (Bug#8545)
12586 * doprnt.c (doprnt): Document the set of format control sequences
12587 supported by the function. Use SAFE_ALLOCA instead of always
12590 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12591 is one byte too soon. Don't use xrealloc; instead xfree and
12594 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12596 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12599 * gnutls.c: Renamed global_initialized to
12600 gnutls_global_initialized. Added internals for the
12601 :verify-hostname-error, :verify-error, and :verify-flags
12602 parameters of `gnutls-boot' and documented those parameters in the
12603 docstring. Start callback support.
12604 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12605 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12606 on error. Return error code.
12607 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12608 (emacs_gnutls_read): Likewise.
12609 (Fgnutls_boot): Return handshake error code.
12610 (emacs_gnutls_handle_error): New function.
12611 (wsaerror_to_errno): Likewise.

12614 (emacs_gnutls_push): Likewise.
12616 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12617 (emacs_gnutls_push): Likewise.
12619 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
12621 * process.c (wait_reading_process_output): Check if GnuTLS
12622 buffered some data internally if no FDs are set for TLS

13128 * font.c (font_close_object): Now static.
13129 * font.h (font_close_object): Remove.
13130 * fontset.c (FONTSET_OBJLIST): Remove.
13131 (free_realized_fontset) #if-0 the body, which does nothing.
13132 (face_suitable_for_char_p): #if-0, as it's never called.
13133 * fontset.h (face_suitable_for_char_p): Remove decl.
13134 * xfaces.c (face_at_string_position):
13135 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
13136 since 0 is always ASCII.
13138 * fns.c (weak_hash_tables): Now static.
13140 * fileio.c: Make symbols static if they're not exported.

13159 * editfns.c, lisp.h (get_operating_system_release): Remove.
13160 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
13161 worth the hassle of breaking this out.
13163 * xterm.c: Make symbols static if they're not exported.
13164 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
13165 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

13267 * buffer.c (buffer_count): Remove unused var.

13271 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13272 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13273 exported only to the debugger.

13276 * atimer.h (run_all_atimers): Remove; not exported.
13278 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13279 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13280 was inaccessible from Lisp.
13281 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13282 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13284 alloc.c: Import and export fewer symbols, and remove unused items.
13285 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13287 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13288 it's not optimized away by whole-program optimization.
13289 (message_enable_multibyte, free_misc): Remove.
13290 (catchlist, handlerlist, mark_backtrace):
13291 Declare only if BYTE_MARK_STACK.

13300 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13301 (mark_backtrace): Define only if BYTE_MARK_STACK.
13302 * xdisp.c (message_enable_multibyte): Now static.
13304 Declare Lisp_Object Q* variables to be 'static' if not exported.
13305 This makes it easier for human readers (and static analyzers)
13306 to see whether these variables are used from other modules.
13307 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13308 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

13317 Remove decls of unexported vars.
13318 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13320 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13322 Make Emacs functions such as Fatom 'static' by default.
13323 This makes it easier for human readers (and static analyzers)
13324 to see whether these functions can be called from other modules.
13325 DEFUN now defines a static function. To make the function external
13326 so that it can be used in other C modules, use the new macro DEFUE.
13327 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13328 (Finit_image_library):
13329 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13330 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13331 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13332 Remove decls, since these functions are now static.
13333 (Funintern, Fget_internal_run_time): New decls, since these functions
13334 were already external.
13336 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13337 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13343 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13344 Mark functions with DEFUE instead of DEFUN,
13345 if they are used in other modules.
13346 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13347 decls for now-static functions.
13348 * buffer.h (Fdelete_overlay): Remove decl.
13349 * callproc.c (Fgetenv_internal): Mark as internal.
13350 * composite.c (Fremove_list_of_text_properties): Remove decl.

13356 (Funintern): Remove extern decl; now in .h file where it belongs.
13357 * fileio.c (Fmake_symbolic_link): New forward static decl.
13358 * image.c (Finit_image_library): New forward static decl.
13359 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13360 * intervals.h (Fprevious_property_change):
13361 (Fremove_list_of_text_properties): Remove decls.
13362 * keyboard.c (Fthis_command_keys): Remove decl.
13363 (Fcommand_execute): New forward static decl.

13365 (Fcopy_keymap): Now static.
13366 * keymap.h (Flookup_key): Remove decl.
13367 * process.c (Fget_process): New forward static decl.
13368 (Fprocess_datagram_address): Mark as internal.

13379 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13381 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13384 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13386 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13387 when at ZV. (Bug#8487)
13389 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13391 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13393 * keyboard.c (parse_tool_bar_item): Likewise.
13394 * sound.c (sound_cleanup, alsa_close): Likewise.
13395 * termcap.c (tgetent): Likewise.
13396 * xfns.c (x_default_font_parameter): Likewise.
13397 * xsettings.c (read_and_apply_settings): Likewise.
13399 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13400 (overrun_check_free): Protoize.
13402 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13404 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13405 since callers should never pass a negative size.
13406 Change the signature to match that of plain 'read' and 'write'; see
13407 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13408 * lisp.h: Update prototypes of emacs_write and emacs_read.
13410 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13412 * xdisp.c (redisplay_window): Don't try to determine the character
13413 position of the scroll margin if the window start point w->startp
13414 is outside the buffer's accessible region. (Bug#8468)
13416 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13418 Fix write-region and its subroutines for buffers > 2GB.
13419 * fileio.c (a_write, e_write): Modify declaration of arguments and
13420 local variables to support buffers larger than 2GB.
13421 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13423 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13424 argument, local variables, and return value.
13426 * lisp.h: Update prototypes of emacs_write and emacs_read.
13428 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13430 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13432 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13434 Fix more problems found by GCC 4.6.0's static checks.
13436 * xdisp.c (vmessage): Use a better test for character truncation.
13438 * charset.c (load_charset_map): <, not <=, for optimization,
13439 and to avoid potential problems with integer overflow.
13440 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13441 * casetab.c (set_identity, shuffle): Likewise.
13442 * editfns.c (Fformat): Likewise.
13443 * syntax.c (skip_chars): Likewise.
13445 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13446 This also lets GCC 4.6.0 generate slightly better loop code.
13448 * callint.c (Fcall_interactively): <, not <=, for optimization.
13449 (Fcall_interactively): Count the number of arguments produced,
13450 not the number of arguments given. This is simpler and lets GCC
13451 4.6.0 generate slightly better code.
13453 * ftfont.c: Distingish more carefully between FcChar8 and char.
13454 The previous code passed unsigned char * to a functions like
13455 strlen and xstrcasecmp that expect char *, which does not
13456 conform to the C standard.
13457 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13458 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13459 char * when the C standard requires it.
13461 * keyboard.c (read_char): Remove unused var.
13463 * eval.c: Port to Windows vsnprintf (Bug#8435).
13464 Include <limits.h>.
13465 (SIZE_MAX): Define if the headers do not.
13466 (verror): Do not give up if vsnprintf returns a negative count.
13467 Instead, grow the buffer. This ports to Windows vsnprintf, which
13468 does not conform to C99. Problem reported by Eli Zaretskii.
13469 Also, simplify the allocation scheme, by avoiding the need for
13470 calling realloc, and removing the ALLOCATED variable.
13472 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13474 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13475 But keep the doprint source code for now, as we might revamp it
13476 and use it again (Bug#8435).
13477 * lisp.h (doprnt): Remove.
13478 * Makefile.in (base_obj): Remove doprnt.o.
13479 * deps.mk (doprnt.o): Remove.
13481 error: Print 32- and 64-bit integers portably (Bug#8435).
13482 Without this change, on typical 64-bit hosts error ("...%d...", N)
13483 was used to print both 32- and 64-bit integers N, which relied on
13484 undefined behavior.
13485 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13486 * lisp.h (error, verror): Mark as printf-like functions.
13487 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13488 Report overflow in size calculations when allocating printf buffer.
13489 Do not truncate output string at its first null byte.
13490 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13491 Truncate the output at a character boundary, since vsnprintf does not
13493 * charset.c (check_iso_charset_parameter): Convert internal
13494 character to string before calling 'error', since %c now has the
13496 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13497 overflow when computing char to be passed to 'error'. Do not
13498 pass Lisp_Object to 'error'; pass the integer instead.
13499 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13500 formatted with plain %d.
13502 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13504 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13506 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

13516 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13517 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13518 return ssize_t not "int", and use size_t as the buffer length.
13519 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13520 * gnutls.h: Update declarations.
13521 * process.c (read_process_output): Use ssize_t, to match.
13522 (send_process): Likewise.
13524 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13526 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13528 2011-04-09 Chong Yidong <cyd@stupidchicken.com>

13531 Use unsigned char, to match FcChar8 type definition.
13533 * xterm.c (handle_one_xevent):
13534 * xmenu.c (create_and_show_popup_menu):
13535 * xselect.c (x_decline_selection_request)
13536 (x_reply_selection_request): Avoid type-punned deref of X events.
13538 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13540 Fix some uses of `int' instead of EMACS_INT.
13541 * search.c (string_match_1, fast_string_match)
13542 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)

13637 This avoids several warnings with gcc -Wstrict-overflow.
13638 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13639 directly, rather than having caller test rule sign. This avoids
13640 some unnecessary tests.
13641 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13642 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13643 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13645 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13646 (xfont_open): Avoid unnecessary tests.
13648 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13650 * composite.h, composite.c (composition_gstring_put_cache):
13651 Use EMACS_INT, not int, for length.
13653 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13654 breaking out part of COMPOSITION_DECODE_RULE.
13655 (COMPOSITION_DECODE_RULE): Use it.
13656 * composite.c (get_composition_id): Remove unused local vars,
13657 by using the new macro.
13659 * textprop.c (set_text_properties_1): Change while to do-while,
13660 since the condition is always true at first.
13662 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13663 (interval_deletion_adjustment): Return unsigned value.
13666 * process.c (list_processes_1, create_pty, read_process_output):

13691 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13693 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13695 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13696 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13697 can always succeed if overflow has undefined behavior.
13699 * search.c (boyer_moore, wordify): Remove vars set but not used.
13700 (wordify): Omit three unnecessary tests.
13702 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

13712 (Finsert_file_contents): Remove unnecessary code checking fd.
13714 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13715 Check for integer overflow on size calculations.
13717 * buffer.c (Fprevious_overlay_change): Remove var that is set
13720 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13721 Remove vars that are set but not used.
13722 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13723 (timer_check_2): Mark vars as initialized.
13725 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13727 * image.c (lookup_image): Remove var that is set but not used.
13728 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13730 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13731 that are set but not used.
13733 * xfns.c (make_invisible_cursor): Don't return garbage
13734 if XCreateBitmapFromData fails (Bug#8410).
13736 * xselect.c (x_get_local_selection, x_handle_property_notify):
13737 Remove vars that are set but not used.
13739 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13740 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13742 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13743 Remove var that is set but not used.
13744 (scroll_bar_windows_size): Now size_t, not int.
13745 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13746 Check for overflow.
13748 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13749 (map_tty_color) [!defined MSDOS]: Likewise.
13751 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13753 * coding.c: Remove vars that are set but not used.
13754 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13755 All callers changed.
13756 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13757 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13758 (decode_coding_charset): Remove vars that are set but not used.
13760 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13761 that is set but not used.
13763 * print.c (print_object): Remove var that is set but not used.
13765 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13766 The gnulib version avoids calling malloc in the usual case,
13767 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13768 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13769 * filelock.c (current_lock_owner): Likewise.
13770 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13771 * sysdep.c: Include allocator.h, careadlinkat.h.
13772 (emacs_no_realloc_allocator): New static constant.
13773 (emacs_readlink): New function.
13774 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13775 ../lib/careadlinkat.h.
13777 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13779 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13780 first non-nil return value).

13784 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13785 if not defined (Bug#8403).

13794 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13795 and thereabouts. All callers changed.
13796 (get_per_char_metric): Remove parameter `f', unused since
13797 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13801 do not dereference NULL upon failed strdup
13802 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13803 (ns_get_family): Likewise.
13805 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13807 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13809 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13811 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13814 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13816 Add lexical binding.
13818 * window.c (Ftemp_output_buffer_show): New fun.
13819 (Fsave_window_excursion):
13820 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13822 * lread.c (lisp_file_lexically_bound_p): New function.
13823 (Fload): Bind Qlexical_binding.
13824 (readevalloop): Remove `evalfun' arg.
13825 Bind Qinternal_interpreter_environment.
13826 (Feval_buffer): Bind Qlexical_binding.
13827 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13829 (syms_of_lread): Declare `lexical-binding'.
13831 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13833 * keyboard.c (eval_dyn): New fun.
13834 (menu_item_eval_property): Use it.

13838 * fns.c (concat, mapcar1): Accept byte-code-functions.
13840 * eval.c (Fsetq): Handle lexical vars.
13841 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13842 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13843 (FletX, Flet): Obey lexical binding.
13844 (Fcommandp): Handle closures.
13845 (Feval): New `lexical' arg.
13846 (eval_sub): New function extracted from Feval. Use it almost
13847 everywhere where Feval was used. Look up vars in lexical env.
13849 (Ffunctionp): Move from subr.el.
13850 (Ffuncall): Handle closures.
13851 (apply_lambda): Remove `eval_flags'.
13852 (funcall_lambda): Handle closures and new byte-code-functions.
13853 (Fspecial_variable_p): New function.
13854 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13855 but without exporting it to Lisp.
13857 * doc.c (Fdocumentation, store_function_docstring):
13858 * data.c (Finteractive_form): Handle closures.
13860 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13863 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13865 (exec_byte_code): New function extracted from Fbyte_code to handle new
13866 calling convention for byte-code-functions. Add new byte-codes.
13868 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

13878 * xdisp.c (SCROLL_LIMIT): New macro.
13879 (try_scrolling): Use it when setting scroll_limit.
13880 Limit scrolling to 100 screen lines.
13881 (redisplay_window): Even when falling back on "recentering",
13882 position point in the window according to scroll-conservatively,
13883 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13885 (try_scrolling): When point is above the window, allow searching
13886 as far as scroll_max, or one screenful, to compute vertical
13887 distance from PT to the scroll margin position. This prevents
13888 try_scrolling from unnecessarily failing when
13889 scroll-conservatively is set to a value slightly larger than the
13890 window height. Clean up the case of PT below the margin at bottom
13891 of window: scroll_max can no longer be INT_MAX. When aggressive
13892 scrolling is in use, don't let point enter the opposite scroll
13893 margin as result of the scroll.
13894 (syms_of_xdisp) <scroll-conservatively>: Document the
13895 threshold of 100 lines for never-recentering scrolling.

13902 (message_log_check_duplicate): Remove parameters `prev_bol' and
13903 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13904 (redisplay_internal): Remove parameter `preserve_echo_area',
13905 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13907 * indent.c (Fvertical_motion):
13908 * window.c (window_scroll_pixel_based, Frecenter):
13909 Don't pass `need_y_p' to `move_it_by_lines'.
13911 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13913 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13914 steal a few bits to be more compact.
13915 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13916 Remove unneeded casts.
13918 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13920 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13922 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13923 binding" message (bug#7967).
13925 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13927 Fix more problems found by GCC 4.6.0's static checks.
13929 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13930 Remove unused local var.
13932 * editfns.c (Fmessage_box): Remove unused local var.
13934 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13935 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13936 Omit unused local vars.
13937 * window.c (shrink_windows): Omit unused local var.
13938 * menu.c (digest_single_submenu): Omit unused local var.
13939 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13940 Omit unused local var.
13942 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13943 Don't assume string length fits in int.
13944 (keyremap_step, read_key_sequence): Use size_t for sizes.
13945 (read_key_sequence): Don't check last_real_key_start redundantly.
13947 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13948 instead of alloca (Bug#8344).
13950 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13951 (Fbacktrace_frame): Don't assume nframes fits in int.
13953 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13955 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13958 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13960 * cm.c (calccost): Turn while-do into do-while, for clarity.
13962 * keyboard.c (syms_of_keyboard): Use the same style as later
13963 in this function when indexing through an array. This also
13964 works around GCC bug 48267.
13966 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13968 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13970 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13971 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13973 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13974 This avoids undefined behavior on integer overflow, and is a bit
13975 more convenient anyway since it is compared to a size_t variable.
13977 Variadic C functions now count arguments with size_t, not int.
13978 This avoids an unnecessary limitation on 64-bit machines, which
13979 caused (substring ...) to crash on large vectors (Bug#8344).
13980 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13981 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13988 (funcall_lambda, mark_backtrace): Likewise.
13989 * fns.c (concat): Likewise.
13990 * frame.c (x_set_frame_parameters): Likewise.
13991 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13992 0 if not found, not -1. All callers changed.
13994 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13995 (stack_copy_size): Now size_t, not int.
13996 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

14200 * callint.c (Fcall_interactively):
14201 * buffer.c (Fkill_all_local_variables):
14202 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14204 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14205 unconditionally since it does the check itself.
14207 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14209 Fix more problems found by GCC 4.5.2's static checks.
14211 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14212 the first time through the loop, since we know p0 < p1 then.
14213 This also avoids a gcc -Wstrict-overflow warning.
14215 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14216 leading to a memory leak, possible in functions like
14217 load_charset_map_from_file that can allocate an unbounded number
14218 of objects (Bug#8318).
14220 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14221 that could (at least in theory) be that large.
14223 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14224 This is less likely to overflow, and avoids undefined behavior if
14225 overflow does occur. All callers changed. Use strtoul to scan
14226 for the unsigned long integer.
14227 (pint2hrstr): Simplify and tune code slightly.
14228 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14238 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14241 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14243 * process.c (Fmake_network_process): Use socklen_t, not int,
14244 where POSIX says socklen_t is required in portable programs.
14245 This fixes a porting bug on hosts like 64-bit HP-UX, where
14246 socklen_t is wider than int (Bug#8277).
14247 (Fmake_network_process, server_accept_connection):
14248 (wait_reading_process_output, read_process_output):
14251 * process.c: Rename or move locals to avoid shadowing.

14261 Make tparam.h and terminfo.c consistent.
14262 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14263 Include tparam.h instead, since it declares them.
14264 * cm.h (PC): Remove extern decl; tparam.h now does this.
14265 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14266 * terminfo.c: Include tparam.h, to check interfaces.
14267 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14268 (tparam): Adjust signature to match interface in tparam.h;
14269 this removes some undefined behavior. Check that outstring and len
14270 are zero, which they always are with Emacs.
14271 * tparam.h (PC, BC, UP): New extern decls.
14273 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14274 (xftfont_open): Rename locals to avoid shadowing.

14284 * xfont.c (xfont_list_family): Mark var as initialized.
14286 * xml.c (make_dom): Now static.
14288 * composite.c (composition_compute_stop_pos): Rename local to
14290 (composition_reseat_it): Remove unused locals.
14291 (find_automatic_composition, composition_adjust_point): Likewise.
14292 (composition_update_it): Mark var as initialized.
14293 (find_automatic_composition): Mark vars as initialized,
14294 with a FIXME (Bug#8290).
14296 character.h: Rename locals to avoid shadowing.
14297 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14298 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14299 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14300 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14301 to avoid shadowing.
14303 * textprop.c (property_change_between_p): Remove; unused.
14305 * intervals.c (interval_start_pos): Now static.
14307 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14310 Rename locals to avoid shadowing.
14312 * sound.c (wav_play, au_play, Fplay_sound_internal):
14313 Fix pointer signedness.
14314 (alsa_choose_format): Remove unused local var.
14315 (wav_play): Initialize a variable to 0, to prevent undefined
14316 behavior (Bug#8278).
14318 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14320 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14322 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14323 clobbering (Bug#8298).
14324 * sysdep.c (sys_subshell): Likewise.
14325 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14327 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14328 This should get cleaned up, so that child_setup has the
14329 same signature on all platforms.
14331 * callproc.c (call_process_cleanup): Now static.
14332 (relocate_fd): Rename locals to avoid shadowing.
14334 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14336 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14337 not to be necessary, and produces flickering.
14339 2011-03-20 Glenn Morris <rgm@gnu.org>
14341 * config.in: Remove file.
14343 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14345 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14346 are now in src/globals.h.

14373 (sigchld_handler): Now static.
14375 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14376 That way, the code declares only the vars that it needs.

14383 * process.c (allocate_pty): Don't declare stb unless it's needed.
14385 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
14386 (CONSTANTLIM): Remove; unused.
14387 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14388 Define only if needed.
14390 * unexelf.c (unexec): Name an expression,
14391 to avoid gcc -Wbad-function-cast warning.
14392 Use a different way to cause a compilation error if anyone uses
14393 n rather than nn, a way that does not involve shadowing.
14394 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14396 * deps.mk (unexalpha.o): Remove; unused.
14398 New file unexec.h, the (simple) interface for unexec (Bug#8267).
14399 * unexec.h: New file.
14400 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
14401 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
14402 Depend on unexec.h.
14403 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
14404 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:

14462 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14463 some of which prompt warnings from gcc -Wbad-function-cast.
14464 (Fformat_time_string, Fencode_time, Finsert_char):

14493 (Fmemory_limit): Cast sbrk's returned value to char *.
14495 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14500 Use functions, not macros, for up- and down-casing (Bug#8254).
14501 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14502 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14503 to use the following functions instead of these macros.
14504 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14505 EMACS_INT, since callers assume the returned value fits in int.
14506 (upcase1): Likewise, for UPCASE_TABLE.
14507 (uppercasep, lowercasep, upcase): New static inline functions.
14508 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14518 (regex_compile, re_match_2_internal): Mark locals as initialized.
14519 (RETALLOC_IF): Define only if needed.
14520 (WORDCHAR_P): Likewise. This one is never needed, but is used
14521 only in a comment talking about a compiler bug, so put inside
14522 the #if 0 of that comment.
14523 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14524 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14550 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14551 New macros, so that the caller can use some names other than
14552 gcpro1, gcpro2, etc.
14553 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14555 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14556 argument, for consistency with GCPRO2_VAR, etc: it is now the

14559 * dired.c (directory_files_internal, file_name_completion):
14560 Rename locals to avoid shadowing.
14562 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14563 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14564 dired.c's scmp function, had undefined behavior.
14565 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14566 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14567 * buffer.h: ... to here, because these macros use current_buffer,
14568 and the new implementation with inline functions needs to have
14569 current_buffer in scope now, rather than later when the macros
14571 (downcase, upcase1): New static inline functions.
14572 (DOWNCASE, UPCASE1): Reimplement using these functions.
14573 This avoids undefined behavior in expressions like
14574 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14575 from race conditions in accessing the global variables
14576 case_temp1 and case_temp2.
14577 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14578 * lisp.h (case_temp1, case_temp2): Remove their decls.
14579 * character.h (ASCII_CHAR_P): Move from here ...

14585 * fileio.c (file_name_as_directory, directory_file_name):

14588 (file_name_as_directory): Use const pointers when appropriate.
14589 (Fexpand_file_name): Likewise. In particular, newdir might
14590 point at constant storage, so make it a const pointer.

14592 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14594 (Fset_file_times, Finsert_file_contents, auto_save_error):

14599 to avoid shadowing.
14601 * marker.c (bytepos_to_charpos): Remove; unused.
14603 * lisp.h (verify_bytepos, count_markers): New decls,
14604 so that gcc does not warn that these functions aren't declared.
14606 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14607 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14608 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14609 (copy_text): Remove unused local var.

14612 (lock_file_1): Rename local to avoid shadowing.
14614 * buffer.c (fix_overlays_before): Mark locals as initialized.
14615 (fix_start_end_in_overlays): Likewise. This function should be
14616 simplified by using pointers-to-pointers, but that's a different

14619 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14620 (report_overlay_modification): Rename locals to avoid shadowing.

14625 to suppress a gcc -Wclobbered warning that does not seem to be right.
14626 (MAXPATHLEN): Define only if needed.
14628 * process.c (serial_open, serial_configure): Move decls from here ...
14629 * systty.h: ... to here, so that they can be checked.
14631 * fns.c (get_random, seed_random): Move extern decls from here ...
14632 * lisp.h: ... to here, so that they can be checked.
14634 * sysdep.c (reset_io): Now static.

14793 For example, without this patch (encode-time 0 0 0 1 1
14794 1152921504606846976) returns the obviously-bogus value (-948597
14795 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14796 reports time overflow. See
