164 * w32.c (init_environment): Change the default values of many
165 environment variables in dflt_envvars[] to NULL, to avoid pushing
166 them into environment when they were not already defined. Remove
167 the code that deletes site-lisp subdirectories from the default
168 value of EMACSLOADPATH, as it is no longer needed.
169 (check_windows_init_file): Now external, not static. Use
170 Vload_path as is, without adding anything, as this function is now
171 called when Vload_path is already set up.
173 * w32.h (check_windows_init_file): Add prototype.
175 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

180 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
181 any, in the DEFALT argument into the root of the Emacs build or
182 installation tree, as appropriate.
184 * callproc.c (init_callproc_1): Call decode_env_path instead of
185 doing its equivalent by hand.
186 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
187 the code that sets Vexec_path run on MS-Windows.
189 * lread.c (init_lread): Add comments to #ifdef's.
191 * msdos.c (dos_set_window_size, IT_update_begin)
192 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

199 Now constants, not macros.
201 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
203 Remove unnecessary casts involving pointers.
204 These casts are no longer needed now that we assume C89 or later,
205 since they involve casting to or from void *.
206 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
207 (make_pure_float, make_pure_vector):
208 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

216 * xselect.c (x_stop_queuing_selection_requests)
217 (x_get_window_property, x_get_window_property_as_lisp_data):
218 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
219 Remove unnecessary pointer casts.
220 * alloc.c (record_xmalloc): New function.
221 * lisp.h (record_xmalloc): New decl.
222 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
223 more like a function. This is because the pointer cast is not
224 needed. All uses changed.
225 * print.c (print_string, print_error_message): Avoid length recalc.
227 Improve fix for macroexp crash with debugging (Bug#12118).
228 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
229 ARRAY_MARK_FLAG when checking subscripts, because ASET is
230 not supposed to be invoked from the garbage collector.
231 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
232 (gc_aset): New function, which is like ASET but can be
233 used in the garbage collector.
234 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

246 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
247 (map_w32_filename): Improve commentary. Simplify switch.
248 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
249 headers (most versions of MinGW w32api don't).
250 (get_security_info, create_symbolic_link)
251 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
253 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
254 in the argument file name.
255 (sys_access): Call unc_volume_file_attributes only if
256 GetFileAttributes fails with network-related error codes.
257 (sys_rename): Diagnose renaming of a symlink when the user doesn't
258 have the required privileges.
259 (get_file_security_desc_by_name): Renamed from
260 get_file_security_desc.
261 (stat_worker): New function, with most of the guts of 'stat', and
262 with addition of handling of symlinks and support for 'lstat'. If
263 possible, get file's attributes and security information by
264 handle, not by name. Produce S_IFLNK bit for symlinks, when
266 (stat, lstat): New functions, call 'stat_worker'.
267 (symlink, readlink, careadlinkat): Rewritten to create and resolve
268 symlinks when the underlying filesystem supports them.
270 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
272 Fix macroexp crash on Windows with debugging (Bug#12118).
273 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
274 checking subscripts; problem introduced with the recent
275 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
276 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
277 since it's used in non-static inline functions now.
279 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
280 Don't assume buffer size fits in 'int'. Remove unused local.
282 Use C99-style 'extern inline' if available.
283 * buffer.h (BUFFER_INLINE):
284 * category.h (CATEGORY_INLINE):
285 * character.h (CHARACTER_INLINE):
286 * charset.h (CHARSET_INLINE):

300 * composite.c (COMPOSITE_INLINE):
301 * dispnew.c (DISPEXTERN_INLINE):
302 * sysdep.c (SYSTIME_INLINE):
303 Define to EXTERN_INLINE, so that the corresponding functions
304 are compiled into code.
305 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
306 (INLINE_HEADER_END): New macros.
307 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

329 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
331 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
332 This how ASET and AREF are supposed to work, and makes
333 it easier to think about future improvements. See
334 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
335 * charset.h (set_charset_attr): New function.

745 2012-07-27 Eli Zaretskii <eliz@gnu.org>
747 * alloc.c (listn): Fix the order the arguments are consed onto the
750 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
751 enumeration constants, as PURE and HEAP are too general, and clash
752 with other headers and sources, such as gmalloc.c and the
753 MS-Windows system headers. All users changed.
755 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
757 Revert last save_excursion_save and save_excursion_restore changes.

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

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

802 * xfns.c (syms_of_xfns): Likewise.
804 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

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

838 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
839 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
840 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
841 not be usable in #if. This simplifies things.
843 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
845 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
847 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

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

892 add argument, tune behavior, and adjust all callers.
894 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
896 Use typedef for EMACS_INT, EMACS_UINT.
897 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
898 than macros. This simplifies debugging in the usual case, since
899 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
900 and it allows expressions involving EMACS_INT casts.
901 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
903 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
905 * nsterm.m (ns_read_socket): Return early if there is a modal

1763 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1764 Prefer snprintf to strncpy.
1765 * nsterm.m (ns_term_init):
1766 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1767 * nsterm.m (ns_term_init):
1768 Avoid the need for strncpy, by using build_string or
1769 make_unibyte_string directly. Use dtoastr, not snprintf.
1770 * process.c (Fmake_network_process): Diagnose service names that
1771 are too long, rather than silently truncating them or creating

1823 Avoid calls to strlen in path processing functions.
1824 * fileio.c (file_name_as_directory): Add comment. Change to add
1825 srclen argument and return the length of result. Adjust users
1827 (directory_file_name): Fix comment. Change to add srclen argument,
1828 swap 1st and 2nd arguments to obey the common convention. Adjust
1830 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1832 2012-07-10 Glenn Morris <rgm@gnu.org>
1834 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1835 Move PENDING_OUTPUT_COUNT definition to configure.
1837 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1838 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1839 * s/gnu.h (DATA_START): Move definitions to configure.
1841 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1842 We include usg5-4-common.h, which defines them both.
1844 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1845 O_RDONLY already includes it).
1847 Stop ns builds setting the EMACSLOADPATH environment variable.
1848 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1849 Now it does not set EMACSLOADPATH, just returns the load-path string.
1850 * nsterm.h: Update accordingly.
1851 * lread.c [HAVE_NS]: Include nsterm.h.
1852 (init_lread) [HAVE_NS]: Use ns_load_path.

1855 2012-07-09 Glenn Morris <rgm@gnu.org>
1857 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1858 since the included bsd-common.h does so.
1860 Stop ns builds setting the EMACSPATH environment variable.
1861 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1862 (ns_init_paths): Do not set EMACSPATH.
1863 * nsterm.h (ns_exec_path): Add it.
1864 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1867 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1869 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1871 * process.c (wait_reading_process_output): 'waitchannels' was unset
1872 when read_kbd || !NILP (wait_for_cell); fix this.
1874 Add GCC-style 'const' attribute to functions that can use it.
1875 * character.h (char_resolve_modifier_mask):
1876 * keyboard.h (make_ctrl_char):
1877 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1878 (init_character_once, next_almost_prime, init_fns, init_image)
1879 (flush_pending_output, init_sound):

1884 Declare the dummy function with ATTRIBUTE_CONST.
1885 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1886 Add decls with ATTRIBUTE_CONST.
1888 Minor improvements to make_formatted_string.
1889 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1890 where int is good enough, as vsprintf returns an int.
1891 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1893 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1895 Use make_formatted_string to avoid double length calculation.
1896 * lisp.h (make_formatted_string): New prototype.
1897 * alloc.c (make_formatted_string): New function.
1898 * buffer.c (Fgenerate_new_buffer_name): Use it.

1918 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1920 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1922 Move marker debugging code under MARKER_DEBUG.
1923 * marker.c (MARKER_DEBUG): Move marker debugging code under
1924 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1925 for bootstrap with --enable-checking (~3x slowdown reported
1926 by Juanma Barranquero <lekktu@gmail.com>).
1927 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1929 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1931 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1932 See <http://bugs.gnu.org/11825#29>.
1934 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1936 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1937 has no font, use the frame's font. (Bug#11813)
1938 (display_line): Add commentary about displaying truncation glyphs
1940 (produce_special_glyphs): Move here from term.c.
1942 * term.c (produce_special_glyphs): Move to xdisp.c.
1944 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1947 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1949 * xdisp.c (display_line): Avoid warning about implicit declaration
1952 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1954 * lisp.h: Remove empty conditional.
1956 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1958 * lread.c (load_path_check): Now static.
1960 Fix some minor --with-ns problems found by static checking.
1961 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1962 (x_set_font) [!HAVE_X_WINDOWS]:
1963 * image.c (xpm_load_image) [HAVE_NS]:
1964 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1965 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1966 Remove unused local.
1967 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1968 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1969 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1970 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1971 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1972 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1973 Fix pointer signedness problem.
1974 * xfaces.c (FRAME_X_FONT_TABLE):
1975 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1977 2012-07-07 Glenn Morris <rgm@gnu.org>
1979 * lread.c (load_path_check): New function, split from init_lread.
1980 (init_lread): Reorganize. Motivation:
1981 If EMACSLOADPATH is set, check/warn about that rather than the
1982 defaults, which we are not going to use. Hence we can remove
1983 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1984 Don't warn if site-lisp directories are missing.
1985 If not installed, start from a blank load-path, since
1986 PATH_LOADSEARCH refers to the eventual installation directories.
1988 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1990 Support truncation and continuation glyphs on GUI frames, when
1991 fringes are disabled. (Bug#11832)
1992 * xdisp.c (init_iterator): Get dimensions of truncation and
1993 continuation glyphs even if on GUI frames. Adjust
1994 it->last_visible_x on GUI frames when the left or right fringes,
1995 or both, are absent.
1996 (start_display, move_it_in_display_line_to): Handle the case of a
1997 GUI frame without a fringe to display continuation or truncation
1999 (insert_left_trunc_glyphs): Support GUI frames: make sure
2000 truncation glyphs overwrite enough glyphs from the current line to
2001 have sufficient space in pixels.
2002 (display_line): Support truncation and continuation glyphs on GUI
2003 frames. If some spare pixels are left on the line after inserting
2004 the truncation glyphs, fill that space with a stretch glyph of a
2005 suitably computed width.
2007 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2008 produce_glyphs, to support GUI sessions.
2010 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2012 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2014 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2016 Do not require float-time's arg to fit in time_t (Bug#11825).
2017 This works better on hosts where time_t is unsigned, and where
2018 float-time is applied to the (negative) difference between two times.
2019 * editfns.c (decode_time_components): Last arg is now double *,
2020 not int *, and means to store all the result as a double, without
2021 worrying about whether the seconds part fits in time_t.
2022 All callers changed.
2023 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2024 All callers changed.
2025 (Ffloat_time): Do not fail merely because the specified time falls
2026 outside of time_t range.
2028 2012-07-07 Glenn Morris <rgm@gnu.org>
2030 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2041 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2043 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

2045 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2046 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2047 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

2050 * xfont.c (compare_font_names): Redo to omit the need for casts.
2052 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2054 * xfns.c (Fx_change_window_property): Doc fix.
2055 * w32fns.c (Fx_change_window_property): Doc fix.
2057 * w32fns.c (Fx_window_property): Accept the same arguments as the
2058 X Windows version. Doc fix.
2059 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2061 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2062 Eli Zaretskii <eliz@gnu.org>
2064 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2065 Windows-specific code from nt/config.nt moved here.
2066 Obsolete settings removed.
2068 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2070 * process.c: Avoid unnecessary calls to gettime.
2071 (wait_reading_process_output): Don't get the time of day
2072 when gobbling data immediately and not waiting, as there's no need
2073 for it in that case. This removes a FIXME.
2075 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2077 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2078 is defined (Bug#11768).

2083 * marker.c (byte_char_debug_check): Do not perform the check
2084 if buffer is not multibyte.
2085 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2086 Call byte_char_debug_check with correct arguments.
2088 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2090 Compile marker debugging code only if ENABLE_CHECKING is defined.
2091 * marker.c (byte_char_debug_check, count_markers):
2092 Use only if ENABLE_CHECKING is defined.
2093 (byte_debug_flag): Remove.
2094 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2095 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2097 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2099 Avoid code repetition in marker-related functions.
2100 * marker.c (attach_marker): New function.
2101 (Fset_marker, set_marker_restricted, set_marker_both)
2102 (set_marker_restricted_both): Use it.
2103 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2104 Consistently rename charno to charpos.

2125 * window.c (save_window_save): Likewise.
2127 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2129 Do not use Fdelete_overlay in delete_all_overlays
2130 to avoid redundant calls to unchain_overlay.
2131 * buffer.c (drop_overlay): New function.
2132 (delete_all_overlays, Fdelete_overlay): Use it.
2133 * minibuf.c (get_minibuffer): Fix comment.
2135 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2137 Port to OpenBSD 5.1 amd64.
2138 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2139 This is needed for OpenBSD, and should be harmless on all BSD systems.
2140 Also, include <sys/sysctl.h>, as it should be available on all
2141 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2142 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2143 use p_pid member, not kp_proc.pid.
2145 2012-07-06 Glenn Morris <rgm@gnu.org>
2147 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2149 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2160 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2162 Omit needless casts involving void * pointers and allocation.
2163 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2164 as the former is more robust if P's type is changed.
2165 Prefer xzalloc to xmalloc + memset 0.
2166 Simplify malloc-or-realloc to realloc.
2167 Don't worry about xmalloc returning a null pointer.
2168 Prefer xstrdup to xmalloc + strcpy.
2169 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2171 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2172 alloca of a constant.

2177 hscroll is larger than the line width. Fixes long and futile
2178 looping inside extend_face_to_end_of_line (on a TTY) producing
2179 glyphs that are not needed and thrown away.
2181 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

2209 * xdisp.c (window_hscroll_limited): New function.
2210 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2211 coordinates when window's hscroll is set to insanely large

2284 This should be fixed in a better way; see Eli Zaretskii in
2285 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2286 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2288 * fileio.c (time_error_value): Rename from special_mtime.
2289 The old name's problems were noted by Eli Zaretskii in
2290 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2292 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2293 This variable's comment says Emacs needs at least one GDB-visible
2294 symbol of type enum pvec_type, to work around GDB problems.
2295 The symbol's value doesn't matter.
2297 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2298 that causes compilation to fail on pre-C99 compilers.
2300 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2302 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2303 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2305 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2307 * buffer.c (init_buffer_once): Fix initialization of
2308 headers for buffer_defaults and buffer_local_symbols.
2309 Reported by Juanma Barranquero <lekktu@gmail.com>.
2311 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2313 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2314 * lisp.h (enum pvec_type): Use fewer bits.
2315 (PSEUDOVECTOR_SIZE_BITS): New constant.
2316 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2317 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2318 change in pvec_type.
2319 (PSEUDOVECTOR_TYPEP): New macro.
2320 (TYPED_PSEUDOVECTORP): Use it.
2321 * fns.c (internal_equal): Adapt code to extract pvectype.
2322 * emacs.c (gdb_pvec_type): Update type.
2323 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2324 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2325 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2326 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2327 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2328 abusing vector->header.next.nbytes.
2329 (live_vector_p): Use PVEC_TYPE.
2330 (mark_object): Adapt code to extract pvectype. Use switch.
2332 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2334 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2335 Tighten new eassert a bit.
2337 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2339 Fix compilation with --enable-gcc-warnings and -O1
2341 * doprnt.c (doprnt): Change type of tem to int, initialize
2342 to avoid compiler warning. Add eassert.
2343 * search.c (simple_search): Initialize match_byte to avoid
2344 compiler warning. Add eassert.
2346 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2348 Avoid weird behavior with large horizontal scrolls.
2349 Without this change, for example, large hscroll values would
2350 mess up Emacs's display on Fedora 15 x86, presumably due to
2351 overflows in int calculations in the display code.
2352 Also, if buffers had long lines, Emacs would freeze.
2353 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2354 (set_window_hscroll): New function, containing the old guts of
2355 Fset_window_hscroll. Return the clipped value.
2356 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2357 This avoids the need to check against PTRDIFF_MAX.
2359 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2361 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2363 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2365 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2367 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2368 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2369 since GCC 4.4.6 issues a bogus warning for them.
2371 Fix bugs in file timestamp newness comparisons.
2372 * fileio.c (Ffile_newer_than_file_p):
2373 * lread.c (Fload): Use full timestamp resolution of files,
2374 not just the 1-second resolution, so that files that are only
2375 slightly newer still count as newer.
2376 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2377 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2379 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2381 * fileio.c: Improve handling of file time marker. (Bug#11852)
2382 (special_mtime): New function.
2383 (Finsert_file_contents, Fverify_visited_file_modtime):
2384 Use it to set special mtime values consistently.
2386 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2388 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2389 marker for non-existing file. (Bug#11852)
2391 2012-07-03 Glenn Morris <rgm@gnu.org>
2393 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2394 and did not make it into globals.h).
2396 2012-07-03 Tom Tromey <tromey@redhat.com>
2398 * window.c (Fset_window_margins, Fset_window_fringes)
2399 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2400 * textprop.c (Fprevious_property_change): No longer static.
2401 * syntax.c (Fsyntax_table_p): No longer static.
2402 * process.c (Fget_process, Fprocess_datagram_address): No longer
2404 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.

2412 * doc.c (Fdocumentation_property, Fsnarf_documentation):
2414 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
2416 * dired.c (Ffile_attributes): No longer static.
2417 * composite.c (Fcomposition_get_gstring): No longer static.
2418 * callproc.c (Fgetenv_internal): No longer static.
2420 * ccl.h: Remove EXFUNs.
2421 * buffer.h: Remove EXFUNs.
2422 * dispextern.h: Remove EXFUNs.
2423 * intervals.h: Remove EXFUNs.
2424 * fontset.h: Remove EXFUN.
2425 * font.h: Remove EXFUNs.
2426 * dosfns.c (system_process_attributes): Remove EXFUN.
2427 * keymap.h: Remove EXFUNs.
2428 * lisp.h: Remove EXFUNs.
2429 * w32term.h: Remove EXFUNs.
2430 * window.h: Remove EXFUNs.
2431 * xsettings.h: Remove EXFUN.
2432 * xterm.h: Remove EXFUN.
2434 2012-07-03 Glenn Morris <rgm@gnu.org>
2436 * lisp.h (Frandom): Make it visible to C.
2437 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2438 buffer for invisible buffers. (Bug#1229)
2440 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2442 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2443 values which aren't power of 2.
2444 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2445 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2448 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2450 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2452 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2454 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2456 * alloc.c (allocate_vector_block): Remove redundant
2457 calls to mallopt if DOUG_LEA_MALLOC is defined.
2458 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2459 avoid calls to mallopt if zero_vector is returned.
2461 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2463 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2464 is enabled, avoid dereferencing NULL current_sblock if
2467 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2469 Cleanup basic buffer management.
2470 * buffer.h (struct buffer): Change layout to use generic vector
2471 marking code. Fix some comments. Change type of 'clip_changed'
2472 to bitfield. Remove unused #ifndef old.
2473 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2474 (GET_OVERLAYS_AT): Fix indentation.
2475 (for_each_per_buffer_object_at): New macro.
2476 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2477 (Fbuffer_local_variables): Use it.
2478 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2479 * alloc.c (allocate_buffer): Adjust to match new layout of
2480 struct buffer. Fix comment.
2481 (mark_overlay): New function.
2482 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2483 Lisp area of struct buffer.
2484 (mark_object): Use it. Adjust marking of misc objects
2485 and related comments.
2487 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2489 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2490 wrapper that is not needed because the wrapped code is a no-op (zero
2491 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2492 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2494 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2496 * alloc.c (mark_buffer): Simplify. Remove prototype.
2497 (mark_object): Add comment. Reorganize marking of vector-like
2498 objects. Use CHECK_LIVE for all vector-like objects except buffers
2499 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2500 redundant calls to mark_vectorlike for bool vectors.
2502 2012-06-30 Glenn Morris <rgm@gnu.org>
2504 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2506 * epaths.in (PATH_SITELOADSEARCH): New.
2507 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2508 This is rather than relying on --enable-locallisppath elements
2509 having "site-lisp" in their names. (Bug#10208#25, 11658)
2511 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2513 * w32proc.c (sys_select): Accept and ignore one more argument.
2515 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2517 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2518 (pselect) [!MS_DOS]: Redirect to sys_select.
2520 * sysdep.c: Don't include dos.h and dosfns.h.
2522 * process.c (sys_select):
2523 * msdos.c (sys_select): Accept one more argument and ignore it.
2525 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2526 adapt data types and code to that.
2529 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2530 which clashes with the gnulib function of the same name.
2532 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2534 * font.c (font_style_to_value, font_style_symbolic)
2535 (font_prop_validate_style): Add type checks for values in
2538 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2540 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2543 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2545 * xdisp.c (try_window_id): Undo last change.
2547 * w32.c (getwd): Adjust commentary about startup_dir.
2548 (init_environment): Always call sys_access, even in non-MSVC
2549 builds. Don't chdir to the directory of the Emacs executable.
2550 This undoes code from 1997 which was justified by the need to
2551 "avoid conflicts when removing and renaming directories". But its
2552 downside was that every relative file name was being interpreted
2553 relative to the directory of the Emacs executable, which can never
2554 be TRT. In particular, it broke sys_access when called with
2555 relative file names.
2556 (sys_access): Map GetLastError to errno.
2558 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2560 * window.h (struct window): Change type of 'fringes_outside_margins'
2561 to bitfield. Fix comment. Adjust users accordingly.
2562 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2564 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2567 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2569 * gnutls.c (emacs_gnutls_handshake):
2570 Add QUIT to make the loop interruptible.
2572 2012-06-29 Glenn Morris <rgm@gnu.org>
2574 * charset.c (init_charset): Make lack of etc/charsets fatal.
2576 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2578 * editfns.c (region_limit): Fix type mismatch.
2580 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2582 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2583 undefined. Convert from xassert to eassert.
2584 * nsmenu.m: Convert from xassert to eassert.
2585 * nsterm.m: Likewise.
2587 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2589 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2591 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2593 Avoid integer overflow on scroll-left and scroll-right.
2594 * window.c (HSCROLL_MAX): New macro.
2595 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2596 overflow when requested scroll falls outside ptrdiff_t range.
2598 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2600 * window.h (struct window): Change type of 'hscroll',
2601 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2602 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2603 Adjust users accordingly.
2604 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2605 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2606 from EMACS_INT to ptrdiff_t.
2607 (make_window): Omit redundant initialization.
2609 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2613 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2615 * window.h (struct window): Change type of 'use_time' and
2616 'sequence_number' from Lisp_Object to int.

2626 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2627 adjust comments accordingly.

2676 * alloc.c (allocate_string_data): Remove dead code.
2677 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2678 avoid GCC warning about unused macro.
2680 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2682 * alloc.c (allocate_string): Omit intervals initialization.
2683 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2684 as in make_pure_string and make_pure_c_string.
2686 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2688 * alloc.c (allocate_string): Fix last change.
2690 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2740 * alloc.c: Remove build_string.
2741 * lisp.h: Define build_string as static inline. This provides
2742 a better opportunity to optimize away calls to strlen when the
2743 function is called with compile-time constant argument.
2744 * image.c (imagemagick_error): Convert to build_string.
2745 * w32proc.c (sys_spawnve): Likewise.
2746 * xterm.c (x_term_init): Likewise.
2748 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2750 Use sprintf return value instead of invoking strlen on result.
2751 In the old days this wasn't portable, since some sprintf
2752 implementations returned char *. But they died out years ago and
2753 Emacs already assumes sprintf returns int.
2754 Similarly for float_to_string.
2755 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2756 * ccl.c (ccl_driver):
2757 * character.c (string_escape_byte8):

2760 * print.c (print_object):
2761 * xdisp.c (message_dolog):
2762 * xfns.c (syms_of_xfns):
2763 Use sprintf or float_to_string result to avoid need to call strlen.
2764 * data.c (Fnumber_to_string):
2765 Use make_unibyte_string, since the string must be ASCII.
2766 * lisp.h, print.c (float_to_string): Now returns int length.
2767 * term.c (produce_glyphless_glyph):
2768 Use sprintf result rather than recomputing it.
2770 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2771 * Makefile.in (ALL_CFLAGS):
2772 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2775 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>

2868 * dispnew.c (Fsleep_for, sit_for):
2869 * keyboard.c (kbd_buffer_get_event):
2870 * process.c (Faccept_process_output):
2871 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2872 This improves on the previous patch, which introduced a bug
2873 when time_t is unsigned and as wide as intmax_t.
2874 See <http://bugs.gnu.org/9000#51>.
2876 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2893 Privately reported by Herbert J. Skuhra.
2894 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

2905 language ID in the event parameters.
2907 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2939 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2941 Support higher-resolution time stamps (Bug#9000).
2942 The time stamps are only nanosecond-resolution at the C level,
2943 since that's the best that any real-world system supports now.
2944 But they are picosecond-resolution at the Lisp level, as that's
2945 easy, and leaves room for future OS improvements.
2947 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2950 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2951 Don't get current time unless it's needed.
2953 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2954 now provides it if it's absent.
2955 (start_atimer): Port to higher-res time stamps.
2956 Check for time stamp overflow. Don't get current time more
2957 often than is needed.
2959 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2960 Include systime.h, not time.h.
2961 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2963 * dired.c: Include stat-time.h.
2964 (Ffile-attributes): File times now have higher resolution.

2967 (struct image): Timestamp now has higher resolution.
2969 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2970 has at least microseconds now. All uses removed.
2971 (update_frame, update_single_window, update_window, update_frame_1)
2972 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2974 * editfns.c (time_overflow): Now extern.
2975 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2976 (float-time, Fformat_time_string, Fcurrent_time_string)
2977 (Fcurrent_time_zone): Accept and generate higher-resolution

2980 (decode_time_components, lisp_seconds_argument): New functions.
2981 (make_time): Now static.
2982 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2983 Report an error if the time is invalid, rather than having the caller
2986 * fileio.c: Include <stat-time.h>
2987 (Fcopy_file): Copy higher-resolution time stamps.
2988 Prefer to set the time stamp via a file descriptor if that works.
2989 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2990 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2991 (Fvisited_file_modtime, Fset_visited_file_modtime):
2992 Support higher-resolution time stamps.
2994 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2996 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2998 * image.c (prepare_image_for_display, clear_image_cache)
2999 (lookup_image): Port to higer-resolution time stamps.
3001 * keyboard.c (start_polling, bind_polling_period):
3002 Check for time stamp overflow.
3003 (read_char, kbd_buffer_get_event, timer_start_idle)
3004 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3005 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3006 Port to higher-resolution time stamps. Do not assume time_t is signed.
3007 (decode_timer): New function. Timers are now vectors of length 9,
3008 not 8, to accommodate the picosecond component.
3009 (timer_check_2): Use it.
3011 * nsterm.m (select_timeout, timeval_subtract): Remove.
3012 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3013 as they're a bit more accurate and handle overflow better.
3014 (ns_select): Change prototype to be compatible with pselect.
3015 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3016 * nsterm.h (ns_select): Adjust prototype.
3018 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3019 us-resolution time stamps.
3020 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3022 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3024 * lisp.h (time_overflow): New decl.
3025 (wait_reading_process_output): First arg is now intmax_t, not int,
3026 to accommodate larger waits.
3028 * process.h (struct Lisp_Process.read_output_delay):
3029 Now counts nanoseconds, not microseconds.
3030 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3032 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3033 (wait_reading_process_output):
3034 Port to ns-resolution time stamps.
3035 (Faccept_process_output, wait_reading_process_output):
3036 Check for time stamp overflow. Do not assume time_t is signed.
3037 (select_wrapper): Remove; we now use pselect.
3038 (Fprocess_attributes): Now generates ns-resolution time stamps.
3040 * sysdep.c: Include utimens.h. Don't include utime.h
3041 or worry about struct utimbuf; gnulib does that for us now.
3042 (gettimeofday): Remove; gnulib provides a substitute.
3043 (make_timeval): New function.
3044 (set_file_times): Now sets ns-resolution time stamps.
3045 New arg FD; all uses changed.
3046 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3047 (system_process_attributes):
3048 Now returns ns-resolution time stamp. All uses changed.
3049 Check for time stamp overflow.
3051 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3052 provides a substitute now.
3054 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3055 since it guarantees struct timespec.
3056 (EMACS_TIME): Now struct timespec, so that we can support
3057 ns-resolution time stamps.
3058 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3059 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3060 (EMACS_USECS): Remove.
3061 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3062 so multiply the arg by 1000 before storing it.
3063 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3065 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3066 Port to ns-resolution time stamps.
3067 (EMACS_TIME_NEG_P): Remove; replaced by....
3068 (EMACS_TIME_SIGN): New macro.
3069 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3070 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3071 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3072 (make_timeval, make_lisp_time, decode_time_components): New decls.
3073 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3074 that it mishandled time_t overflow. You can't compare by subtracting!
3075 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3076 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3078 * term.c: Include <sys/time.h>.
3079 (timeval_to_Time): New function, for proper overflow wraparound.

3084 (Fprimitive_undo): Use them when restoring time stamps.
3086 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3087 (w32_get_internal_run_time):
3088 Port to higher-resolution Emacs time stamps.
3089 (ltime): Now accepts single 64-bit integer, as that's more convenient
3092 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3094 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3095 for compatibility with pselect. Support ns-resolution time stamps.
3097 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3099 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3100 Check for time stamp overflow, and support ns-resolution time stamps.
3102 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3103 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3104 (timeval_subtract): Remove; no longer needed.
3105 (XTflash, XTring_bell, x_wait_for_event):
3106 Port to ns-resolution time stamps. Don't assume time_t is signed.
3108 2012-06-22 Chong Yidong <cyd@gnu.org>

3112 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3114 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3115 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3116 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3117 staticidx goes up to 1597 out of 1600 = 0x640.)
3119 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3121 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3122 Otherwise, the umask might be mistakenly 0 while handling input signals.

3143 (unwind_format_mode_line): Restore them.
3144 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3146 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3147 since tty frames can be explicitly named.
3148 (prepare_menu_bars): Likewise.
3150 * term.c (Ftty_top_frame): New function.
3152 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

3155 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3156 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3157 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3158 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3159 (METER_1, METER_2): Simplify.
3161 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3163 * data.c (Fdefalias): Return `symbol' (bug#11686).
3165 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3167 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3168 gets killed during executing of this function (Bug#11665).
3169 Try to always return Qt when the buffer has been actually killed.
3170 (Vkill_buffer_query_functions): In doc-string say that functions
3171 run by this hook should not change the current buffer.
3173 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3175 Fix recently-introduced process.c problems found by static checking.
3176 * process.c (write_queue_push, write_queue_pop, send_process):

3179 (send_process): Remove unused local.
3181 2012-06-17 Chong Yidong <cyd@gnu.org>

3193 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3195 * lisp.h (eassert): Assume C89 or later.
3196 This removes the need for CHECK.
3197 (CHECK): Remove. Its comments about always evaluating its
3198 argument were confusing, as 'eassert' typically does not evaluate
3201 * coding.c (produce_chars): Use ptrdiff_t, not int.
3203 * xterm.c (x_draw_underwave): Check for integer overflow.
3204 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
3206 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
3208 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

3388 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3389 code works fine either way, and efficiency is not a concern here,
3390 as the union type is for debugging, not for production.
3391 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3392 Use an inline function on all platforms when using the union type,
3393 since this is simpler and 'static inline' can be used portably
3395 (LISP_INITIALLY_ZERO): New macro.
3396 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

3537 * doprnt.c (doprnt): Truncate multibyte char correctly.
3538 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3539 would mishandle a string argument "Xc" if X was a multibyte
3540 character of length 2: it would truncate after X's first byte
3541 rather than including all of X.

3594 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3595 Convert pctcpu and pctmem to Lisp float properly.

3615 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3616 fields from Lisp_Object to bitfield. Adjust users accordingly.

3624 and 'double' in a couple of places.
3626 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3628 * xdisp.c (handle_stop): Detect whether we have overlay strings
3629 loaded by testing it->current.overlay_string_index to be
3630 non-negative, instead of checking whether n_overlay_strings is
3631 positive. (Bug#11587)

3641 * search.c (search_buffer): Remove calls to
3642 r_alloc_inhibit_buffer_relocation, as it is now called by
3643 maybe_unify_char, which was the cause of relocation of buffer text
3646 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3648 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3649 for the duration of call to load_charset, to avoid problems with
3650 callers of maybe_unify_char that access buffer text through C
3653 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3654 decrement the inhibition flag, instead of just setting or
3657 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3659 Remove obsolete '#define static' cruft.
3660 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3661 This #undef was "temporary" in 2000; it is no longer needed

3664 (gray_bitmap_bits): Remove; no longer needed.

3709 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3710 Bug#9642, but explicitly check that the buffer the overlay would
3711 be moved to is live and rearrange lines to make sure that errors
3712 will not put the overlay in an inconsistent state.
3713 (Fdelete_overlay): Cosmetics.
3715 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3717 * w32term.c (my_bring_window_to_top): New function.

3724 by calling BringWindowToTop.
3726 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3727 (WM_EMACS_END): Increase by one.
3729 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3731 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3732 This avoids undefined behavior that might cause the eassert
3733 to not catch an out-of-range value.
3735 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3737 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3747 when referring to sectname field in printf format.
3749 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3751 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3752 Only r_alloc_inhibit_buffer_relocation needed to be added;
3753 the others were already declared.
3755 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3756 before checking whether it's out of range. Put the check inside
3758 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3760 2012-05-27 Ken Brown <kbrown@cornell.edu>
3762 * callproc.c (Fcall_process): Restore a line that was accidentally
3763 commented out in the 2011-02-13 change (bug#11547).
3765 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3767 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3768 defined on ralloc.c.
3770 * buffer.c [REL_ALLOC]: Remove prototypes of
3771 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3772 they are now on lisp.h.
3774 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3776 * search.c (search_buffer): Use it to inhibit relocation of buffer
3777 text while re_search_2 is doing its job, because re_search_2 is
3778 passed C pointers to buffer text. (Bug#11519)
3780 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3783 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3784 state after an additional call to move_it_in_display_line_to, keep
3785 the values of it->max_ascent and it->max_descent found for the
3787 (pos_visible_p): Revert the comparison against bottom_y to what it
3788 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3791 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3793 Fix coding-related core dumps with gcc -ftrapv.
3794 The code was computing A - B, where A and B are pointers, and B is
3795 random garbage. This can lead to core dumps on platforms that
3796 have special pointer registers, and it also leads to core dumps on
3797 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3798 A - B only when B is initialized properly.
3799 * coding.c (coding_set_source, coding_set_destination): Return void.
3800 (coding_change_source, coding_change_destinations): New functions,
3801 with the old behaviors of coding_set_source and coding_set_destination.
3802 All callers that need an offset changed to use these new functions.
3804 2012-05-26 Glenn Morris <rgm@gnu.org>
3806 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3808 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3810 Extend mouse support on W32 text-mode console.
3811 * xdisp.c (draw_row_with_mouse_face):
3812 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3814 * w32console.c: Include window.h.
3815 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3817 (initialize_w32_display): Initialize mouse-highlight data.
3819 * w32inevt.c: Include termchar.h and window.h.
3820 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3821 moves, call note_mouse_highlight. If help_echo changed, call
3822 gen_help_event to produce help-echo message in the echo area.
3823 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3826 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3828 * lread.c (read1): Simplify slightly to avoid an overflow warning
3829 with GCC 4.7.0 on x86-64.
3831 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3833 * bidi.c (bidi_mirror_char): Revert last change: an int is
3834 definitely wide enough here.
3836 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3838 Fix integer width and related bugs (Bug#9874).

3849 (allocate_pseudovector):
3850 Use int, not EMACS_INT, where int is wide enough.
3851 (inhibit_garbage_collection, Fgarbage_collect):
3852 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3853 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3854 int might not be wide enough.

3869 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3870 (Foverlay_recenter, last_overlay_modification_hooks_used)
3871 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3872 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3873 (validate_region): Omit unnecessary test for b <= e,
3874 since that's guaranteed by the previous test.
3875 (adjust_overlays_for_delete): Avoid pos + length overflow.
3876 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3877 (report_overlay_modification):
3878 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3879 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3880 Omit pointer cast, which isn't needed anyway, and doesn't work
3881 after the EMACS_INT -> ptrdiff_t change.

3883 * buffer.h: Adjust decls to match defn changes elsewhere.

3888 not int, to avoid needless 32-bit limit on 64-bit hosts.
3889 (exec_byte_code): Use tighter memory-full test, one that checks
3890 for alloca overflow. Don't compute the address of the object just
3891 before an array, as that's not portable. Use EMACS_INT, not
3892 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3893 * callint.c (Fcall_interactively):
3894 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3905 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3906 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3907 (casify_object): Avoid integer overflow when overallocating buffer.
3908 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3909 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3910 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3911 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3912 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3913 integers are now checked earlier. All uses replaced with XINT.
3915 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3916 For CCL_MapSingle, check that content and value are in int range.
3917 (ccl_driver, Fregister_code_conversion_map):
3918 Check that Vcode_version_map_vector is a vector.
3919 (resolve_symbol_ccl_program): Check that vector header is in range.
3920 Always copy the vector, so that we can check its contents reliably
3921 now rather than having to recheck each instruction as it's being
3922 executed. Check that vector words fit in 'int'.
3923 (ccl_get_compiled_code, Fregister_ccl_program)
3924 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3925 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3926 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3927 contents are in range.
3928 (Fccl_execute_on_string): Check that status is in range.
3929 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3930 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3931 Accept and return EMACS_INT, not int, because callers can pass values
3933 (c_string_width, strwidth, lisp_string_width, chars_in_text)

3936 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3937 (string_escape_byte8, Fget_byte):
3938 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3939 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3940 avoid mishandling large integers.
3941 * character.h: Adjust decls to match defn changes elsewhere.

3950 (Fdefine_charset_internal): Check ranges here, more carefully.
3951 Don't rely on undefined behavior with signed left shift overflow.
3952 Don't assume unsigned int fits into fixnum, or that fixnum fits
3953 into unsigned int. Don't require max_code to be a valid fixnum;
3954 that's not true for gb10830 4-byte on a 32-bit host. Allow
3955 invalid_code to be a cons, for the same reason. Require code_offset
3956 to be a character. Avoid int overflow if max_char is close
3958 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3959 this is intended anyway and avoids some undefined behavior.
3960 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3961 INDEX_TO_CODE_POINT, as that's what it expects.
3962 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3963 * charset.h (DECODE_CHAR): Return int, not unsigned;
3964 this is what was intended anyway, and it avoids undefined behavior.
3965 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3966 integer-overflow issues.
3967 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3968 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3969 where the argument is EMACS_INT, and this behavior is not intended.
3970 * chartab.c (Fmake_char_table, Fset_char_table_range)
3971 (uniprop_get_decoder, uniprop_get_encoder):
3972 Don't assume fixnum fits in int.
3973 * cmds.c (move_point): New function, that does the gist of
3974 Fforward_char and Fbackward_char, but does so while checking
3975 for integer overflow more accurately.
3976 (Fforward_char, Fbackward_char): Use it.
3977 (Fforward_line, Fend_of_line, internal_self_insert)
3978 (internal_self_insert):
3979 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4016 Don't access memory outside of the args array.
4017 (Fdefine_coding_system_internal): Check for charset-id overflow.

4778 already have overlays loaded.
4779 (handle_single_display_spec): Before returning without displaying
4780 fringe bitmap, synchronize the bidi iterator with the main display
4781 iterator, by calling iterate_out_of_display_property.
4782 (iterate_out_of_display_property): Detect buffer iteration by
4783 testing that it->string is a Lisp string.
4784 (get_next_display_element): When the current object is exhausted,
4785 and there's something on it->stack, call set_iterator_to_next to

4788 proceed to consider_string_end without incrementing string
4789 position. Don't increment display vector index past the end of
4790 the display vector. (Bug#11417)
4791 (pos_visible_p): Don't report a position visible when move_it_to
4792 stopped at the last line of window, which happens to be scanned
4793 backwards by the bidi iteration. (Bug#11464)
4795 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4797 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4798 and right-margin display specs even if the spec is invalid or we
4799 are on a TTY, and thus unable to display on the fringes.
4800 That's because the text with the property will not be displayed anyway,
4801 so we need to signal to the caller that this is a "replacing"
4802 display spec. This fixes display when the spec is invalid or we
4805 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4807 * unexaix.c (make_hdr): Fix typo in prototype.

4855 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4856 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4857 Initialize xd_registered_buses.
4859 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4861 Untag more efficiently if USE_LSB_TAG.
4862 This is based on a proposal by YAMAMOTO Mitsuharu in
4863 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4864 For an admittedly artificial (nth 8000 longlist) benchmark on
4865 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4866 Emacs's overall text size by 1%.
4867 * lisp.h (XUNTAG): New macro.
4868 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4869 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4870 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4871 * eval.c (Fautoload):
4872 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4873 * frame.h (XFRAME): Use XUNTAG.
4875 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4876 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4877 Remove unportable assumptions about print widths of types like
4879 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4880 intptr_t when converting between pointer and integer, to avoid GCC
4881 warnings about wrong width.
4883 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4885 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4886 stack for each reader_thread, instead of defaulting to 8MB
4887 determined by the linker. This avoids failures in creating
4888 subprocesses on Windows 7, see the discussion in this thread:
4889 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4891 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4893 Fix up display of the *Minibuf-0* buffer in the mini window.
4894 * keyboard.c (read_char): Don't clear the echo area if there's no
4896 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4897 contents of *Minibuf-0*) if there's no message displayed in its stead.
4899 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4901 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4904 2012-05-06 Chong Yidong <cyd@gnu.org>
4906 * lisp.mk (lisp): Update.
4908 2012-05-05 Jim Meyering <meyering@redhat.com>
4910 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4912 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4914 * data.c (PUT_ERROR): New macro.
4915 (syms_of_data): Use it. Add new error type `user-error'.
4916 * undo.c (user_error): New function.
4917 (Fprimitive_undo): Use it.
4918 * print.c (print_error_message): Adjust print style for `user-error'.
4919 * keyboard.c (user_error): New function.
4920 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4922 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4924 Do not limit current-time-string to years 1000..9999.
4925 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4926 (Fcurrent_time_string): Support any year that is supported by the
4927 underlying localtime representation. Don't use asctime, as it
4928 has undefined behavior for years outside the range -999..9999.
4930 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4932 Fix race conditions involving setenv, gmtime, localtime, asctime.
4933 Without this fix, interrupts could mess up code that uses these
4934 nonreentrant functions, since setting TZ invalidates existing
4935 tm_zone or tzname values, and since most of these functions return
4936 pointers to static storage.
4937 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4938 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4939 Grow the critical sections to include not just invoking
4940 localtime/gmtime, but also accessing these functions' results
4941 including their tm_zone values if any, and any related TZ setting.
4942 (format_time_string): Last arg is now struct tm *, not struct tm **,
4943 so that the struct tm is saved in the critical section.
4944 All callers changed. Simplify allocation of initial buffer, partly
4945 motivated by the fact that memory allocation needs to be outside
4946 the critical section.
4948 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4950 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4951 with RESET_INTERVAL.
4953 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4954 Remove duplicated buffer name initialization.
4956 2012-05-02 Jim Meyering <jim@meyering.net>
4958 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4960 * xfns.c (x_window): Use xstrdup (Bug#11375).
4962 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4964 * xdisp.c (pos_visible_p): If already at a newline from the
4965 display string before the 'while' loop, don't walk back the glyphs
4966 from it3.glyph_row. Solves assertion violation when the display
4967 string begins with a newline (egg.el). (Bug#11367)
4969 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4971 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4974 2012-05-01 Glenn Morris <rgm@gnu.org>
4976 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4977 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4978 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4979 All were removed before 23.1.
4981 * dispnew.c: Remove HAVE_LIBNCURSES test;
4982 it is always true on relevant platforms.
4984 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4985 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4987 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4989 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4991 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4992 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4995 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4997 Do not avoid creating empty evaporating overlays (Bug#9642).
4998 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4999 That is, do not delete an evaporating overlay if it becomes
5000 empty after its bounds are adjusted to fit within its buffer.
5001 This fix caused other problems, and I'm reverting it until we get
5002 to the bottom of them.
5004 2012-04-27 Chong Yidong <cyd@gnu.org>
5006 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5008 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5010 * xdisp.c (pos_visible_p): If the window start position is beyond
5011 ZV, start the display from buffer beginning. Prevents assertion
5012 violation in init_iterator when the minibuffer window is scrolled
5015 * window.c (window_scroll_pixel_based): Likewise.
5017 2012-04-27 Chong Yidong <cyd@gnu.org>
5019 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5021 2012-04-27 Glenn Morris <rgm@gnu.org>
5023 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5024 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5026 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5028 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5029 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5031 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5033 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5034 display element, check also the underlying string or buffer
5035 character. (Bug#11341)
5037 * w32menu.c: Include w32heap.h.
5038 (add_menu_item): If the call to AppendMenuW (via
5039 unicode_append_menu) fails, disable Unicode menus only if we are
5040 running on Windows 9X/Me.
5042 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5044 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5045 (xgetint): Add missing shift for LSB tags.
5047 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5049 * keyboard.c (read_char): Don't wipe echo area for select window
5050 events: These might get delayed via `mouse-autoselect-window'
5053 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5055 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5056 manipulation of :loaded-from data.
5058 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5060 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5061 now a cons (bug#11311).
5063 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5065 Do not create empty overlays with the evaporate property (Bug#9642).
5066 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5067 if it becomes empty after its bounds are adjusted to fit within
5068 its buffer. Without this fix, in a nonempty buffer (let ((o
5069 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5070 yields an empty overlay that has the evaporate property, which is
5071 not supposed to happen.
5073 Fix minor GTK3 problems found by static checking.
5074 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5075 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5076 (struct _EmacsFixedClass, emacs_fixed_get_type):

5084 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5085 (EMACS_FIXED_GET_CLASS): Remove; unused.
5086 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5088 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5089 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5091 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5093 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5094 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5095 (__malloc_size_t, __malloc_ptrdiff_t):
5096 Remove. All uses removed, replaced by the definiens if needed,
5097 since we can assume C89 or better now.
5098 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5099 (protect_malloc_state, align, get_contiguous_space)
5100 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5106 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5107 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5108 Define using prototypes, not old style.
5109 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5110 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5111 (align): Don't assume that signed integer overflow wraps around.
5112 Omit unused local var.
5113 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5114 (_free_internal_nolock, memalign, mallochook, reallochook):

5173 * alloc.c: Handle unusual debugging option combinations.
5174 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,

5188 * sysdep.c [__FreeBSD__]: Minor cleanups.
5189 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5190 Use Emacs indenting style more consistently. Avoid some casts.
5191 Use 'double' consistently rather than mixing 'float' and 'double'.

5232 farther than the first row after the header line, if any.
5233 Don't consider the header-line row as "partially visible", even if
5234 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

5289 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
5290 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5291 [REL_ALLOC]: ... to here, to check interface.
5292 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5293 Remove decls. This fixes an "It stinks!".
5295 * alloc.c (which_symbols): Fix alignment issue / type clash.
5297 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5299 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5302 * alloc.c (union aligned_Lisp_Symbol): Define.
5303 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
5304 aligned_Lisp_Symbol instead of struct Lisp_Symbol.
5305 (union aligned_Lisp_Misc): Define.
5306 (MARKER_BLOCK_SIZE, struct marker_block): Use union
5307 aligned_Lisp_Misc instead of union Lisp_Misc.
5308 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
5310 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5312 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5313 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5314 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5315 * s/netbsd.h, s/sol2-6.h:
5316 Remove definition of GC_MARK_STACK, since the default now works.
5317 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5318 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5319 no longer the default.
5320 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5322 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5324 * lread.c (lisp_file_lexically_bound_p):
5325 Fix hang at ";-*-\n" (bug#11238).
5327 2012-04-14 Eli Zaretskii <eliz@gnu.org>
5329 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

5332 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5334 * nsterm.m (constrainFrameRect): Always constrain when there is only
5335 one screen (Bug#10962).
5337 2012-04-13 Ken Brown <kbrown@cornell.edu>
5339 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

5345 2012-04-11 Daniel Colascione <dancol@dancol.org>
5347 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5348 against is gone. It's better to use vfork now so that when Cygwin
5349 gains a new, working vfork, we use it automatically (bug#10398).
5351 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5353 * window.c (save_window_save): Obey window-point-insertion-type.
5355 2012-04-11 Glenn Morris <rgm@gnu.org>
5357 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
5359 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5361 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
5363 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5365 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5366 (force_quit_count): New var.
5367 (handle_interrupt): Use it.
5369 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5371 * w32.c (w32_delayed_load): Record the full path of the library
5372 being loaded (bug#10424).
5374 2012-04-09 Glenn Morris <rgm@gnu.org>
5376 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5377 not just in the obarray, before snarfing them. (Bug#11036)
5379 * Makefile.in ($(leimdir)/leim-list.el):
5380 Pass EMACS rather than BUILT_EMACS.
5382 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5384 * process.c (make_process):
5385 * process.h: Add integer `gnutls_handshakes_tried' member to
5388 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5389 Add convenience `GNUTLS_LOG2i' macro.
5391 * gnutls.c (gnutls_log_function2i): Convenience log function.
5392 (emacs_gnutls_read): Use new log functions,
5393 `gnutls_handshakes_tried' process member, and
5394 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5395 attempts per process (connection).
5397 2012-04-09 Chong Yidong <cyd@gnu.org>
5399 * eval.c (Fuser_variable_p, user_variable_p_eh)
5400 (lisp_indirect_variable): Functions deleted.
5401 (Fdefvar): Caller changed.
5403 * callint.c (Finteractive, Fcall_interactively):
5404 * minibuf.c (Fread_variable): Callers changed.
5406 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5408 * xdisp.c (set_cursor_from_row): If the display string appears in
5409 the buffer at position that is closer to point than the position
5410 after the display string, display the cursor on the first glyph of
5411 the display string. Fixes cursor display when a 'display' text
5412 property immediately follows invisible text. (Bug#11094)
5414 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5416 composite.c: use 'double' consistently
5417 * composite.c (get_composition_id): Use 'double' consistently
5418 instead of converting 'float' to 'double' and vice versa; this is
5419 easier to understand and avoids a GCC warning.
5421 2012-04-09 Glenn Morris <rgm@gnu.org>
5423 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5424 preparation for dumping it with emacs. (Bug#4789)
5425 (leimdir): New variable.
5426 ($(leimdir)/leim-list.el): New rule.
5427 (emacs$(EXEEXT)): Depend on leim-list.el.
5429 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
5430 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
5431 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
5433 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5435 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5438 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5440 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5441 Remove unused local variable.
5443 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5445 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5446 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5447 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5448 objects, as mark_maybe_pointer will catch them otherwise.
5449 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5450 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5452 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5454 Fix typo that broke non-Windows builds.
5455 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5457 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5459 Support building on MS-Windows with libxml2.
5461 * makefile.w32-in (OBJ2): Add xml.$(O).
5462 (GLOBAL_SOURCES): Add xml.c.
5463 ($(BLD)/xml.$(O)): New dependency list.
5465 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5466 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5467 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5468 [!WINDOWSNT]: New macros.
5469 (init_libxml2_functions, libxml2_loaded_p): New functions.
5470 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5471 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5472 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5473 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5475 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5476 Call init_libxml2_functions before calling libxml2 functions.
5477 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5479 * emacs.c: Don't include libxml/parser.h.
5480 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5481 xmlCleanupParser directly.
5483 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5485 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5487 * indent.c (Fvertical_motion): If there is a display string at
5488 point, use it.vpos to compute how many lines to backtrack after
5489 move_it_to point. (Bug#11133)
5491 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5493 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5494 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5495 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5496 macros related to unification of CJK characters. For the details,
5497 see the discussion following the message here:
5498 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5500 2012-04-04 Chong Yidong <cyd@gnu.org>
5502 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5504 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5506 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5507 instead of alloca. (Bug#11138)
5509 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5511 * w32menu.c (is_simple_dialog): Properly check lisp types.
5514 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5516 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5517 position we get to after a call to move_it_to fails the
5518 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5519 only if we wind up in a string from display property. (Bug#11063)
5521 * window.c (Fdelete_other_windows_internal): Invalidate the row
5522 and column information about mouse highlight, so that redisplay
5523 restores it after reallocating the glyph matrices. (Bug#7464)
5525 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5526 string comes from a `display' text property, use the buffer
5527 position of that property as if we actually saw that position in
5529 (move_it_by_lines): Remove the assertion that
5530 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5531 violated when there's a before-string at the beginning of a line.
5534 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5536 * xdisp.c (append_space_for_newline): If the default face was
5537 remapped, use the remapped face for the appended newline.
5538 (extend_face_to_end_of_line): Use the remapped default face for
5539 extending the face to the end of the line.
5540 (display_line): Call extend_face_to_end_of_line when the default
5541 face was remapped. (Bug#11068)
5543 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5545 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5547 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5549 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5551 2012-03-27 Glenn Morris <rgm@gnu.org>
5553 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5556 2012-03-26 Kenichi Handa <handa@m17n.org>
5558 * dispextern.h (struct glyph): Fix previous change. Change the
5559 bit length of glyphless.ch to 25 (Bug#11082).
5561 2012-03-26 Chong Yidong <cyd@gnu.org>
5563 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5564 (command_loop_1): Use it; inhibit selection update for
5565 handle-select-window too (Bug#8996).
5567 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5569 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5571 2012-03-25 Kenichi Handa <handa@m17n.org>
5573 * dispextern.h (struct glyph): Change the bit length of
5574 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5576 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5578 * s/ms-w32.h (tzname): Include time.h before redirecting to
5579 _tzname. Fixes the MSVC build. (Bug#9960)
5581 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5583 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5586 * xterm.c (XTread_socket): Only modify handling_signal if
5587 !SYNC_INPUT. (Bug#11080)
5589 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5591 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5592 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5593 when fetching a multibyte character consumes more bytes than
5594 CHAR_BYTES returns, due to unification of CJK characters in
5595 string_char. (Bug#11073)
5597 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5599 * process.c (wait_reading_process_output): Handle pty disconnect
5600 by refraining from sending oneself a SIGCHLD (bug#10933).
5602 2012-03-22 Chong Yidong <cyd@gnu.org>
5604 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5606 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5607 Mark string as coming from a prefix property.
5608 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5609 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5611 2012-03-21 Chong Yidong <cyd@gnu.org>
5613 * xfaces.c (Vface_remapping_alist): Doc fix.
5615 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5617 * w32proc.c (Fw32_set_console_codepage)
5618 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5621 2012-03-20 Chong Yidong <cyd@gnu.org>
5623 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5624 to reflect default non-nil value of redisplay-dont-pause.
5626 2012-03-19 Kenichi Handa <handa@m17n.org>
5628 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5629 it fit in a valid range (Bug#11003).
5631 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5633 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5634 that is not from display property, accept the row as a "cursor
5635 row" if one of the string's character has a non-nil `cursor'
5636 property. Fixes cursor positioning when there are newlines in
5637 overlay strings, e.g. in icomplete.el. (Bug#11035)
5639 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5641 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5643 2012-03-12 Chong Yidong <cyd@gnu.org>
5645 * eval.c (inhibit_lisp_code): Rename from
5646 inhibit_window_configuration_change_hook; move from window.c.
5648 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5649 * window.c (run_window_configuration_change_hook)
5650 (syms_of_window): Callers changed.
5652 2012-03-11 Chong Yidong <cyd@gnu.org>
5654 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5656 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5658 2012-03-10 Chong Yidong <cyd@gnu.org>
5660 * frame.c (other_visible_frames): Don't assume the selected frame
5661 is visible (Bug#10955).
5663 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5665 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5667 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5669 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5670 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5673 2012-03-03 Glenn Morris <rgm@gnu.org>
5675 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5677 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5679 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5680 position past the first glyph_row that ends at ZV. (Bug#10902)
5681 (redisplay_window, next_element_from_string): Fix typos in
5683 (redisplay_window): Pass to move_it_vertically the margin in
5684 pixels, not in screen lines.
5686 2012-03-02 Glenn Morris <rgm@gnu.org>
5688 * buffer.c (buffer-list-update-hook): Doc fix.
5690 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5692 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5693 push_it before setting up the iterator for the first overlay
5694 string, even if we have an empty string loaded.
5695 (next_overlay_string): If there's an empty string on the iterator
5696 stack, pop the stack. (Bug#10903)
5698 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5700 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5701 Suggested by Stefan Monnier in
5702 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5703 * alloc.c (widen_to_Lisp_Object): New static function.
5704 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5705 and widening them to Lisp_Objects. This would work even if
5706 USE_LSB_TAG is defined and wide integers are used, which might
5707 happen in a future version of Emacs.
5709 2012-02-25 Chong Yidong <cyd@gnu.org>
5711 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5714 * xselect.c (Fx_selection_exists_p): Doc fix.
5715 (x_clipboard_manager_save_all): Print an informative message
5716 before saving to clipboard manager.
5718 2012-02-24 Chong Yidong <cyd@gnu.org>
5720 * keyboard.c (process_special_events): Handle all X selection
5721 requests in kbd_buffer, not just the next one (Bug#8869).
5723 2012-02-23 Chong Yidong <cyd@gnu.org>
5725 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5726 call when setting menu-bar-lines and tool-bar-lines parameters.
5727 (unwind_create_frame_1): New helper function.
5729 * window.c (inhibit_window_configuration_change_hook): New var.
5730 (run_window_configuration_change_hook): Obey it.
5731 (syms_of_window): Initialize it.
5733 2012-02-22 Chong Yidong <cyd@gnu.org>
5735 * xterm.c (x_draw_image_relief): Add missing type check for
5736 Vtool_bar_button_margin (Bug#10743).
5738 2012-02-21 Chong Yidong <cyd@gnu.org>
5740 * fileio.c (Vfile_name_handler_alist): Doc fix.
5742 * buffer.c (Fget_file_buffer): Protect against invalid file
5743 handler return value.
5745 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5747 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5748 when computing $valmask.
5750 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5751 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5752 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5753 It's useless in that case, and it can cause problems on hosts
5754 that allocate halves of EMACS_INT values separately.
5755 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5756 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5757 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5758 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5759 it avoids undefined behavior on hosts where shifting right by more
5760 than the word width has undefined behavior.
5762 2012-02-19 Chong Yidong <cyd@gnu.org>
5764 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5765 (Funhandled_file_name_directory, Ffile_name_as_directory)
5766 (Fdirectory_file_name, Fexpand_file_name)
5767 (Fsubstitute_in_file_name): Protect against invalid file handler
5768 return values (Bug#10845).
5770 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5772 * .gdbinit (pitx): Fix incorrect references to fields of the
5775 2012-02-17 Chong Yidong <cyd@gnu.org>
5777 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5779 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5781 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5782 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5784 2012-02-15 Chong Yidong <cyd@gnu.org>
5786 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

6365 * fileio.c (Finsert_file_contents): Move after-change-function call
6366 to before the "handled:" label, since all "goto handled" appear in
6367 cases where the *-change-functions have already been properly called

6548 to 4 (xorl, subq, cmpq, setbe).
6549 * alloc.c (pure): Always extern now, since that's the
6550 VIRT_ADDR_VARIES behavior.
6551 (PURE_POINTER_P): Use a single comparison, not two, for
6552 consistency with the new puresize.h.

6562 behave as if the cursor position were at the window margin.
6564 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6565 and the cursor position is out of bounds, behave as if the cursor
6566 position were at the window margin. (Bug#10075)

6592 compute_line_metrics.
6593 (compute_line_metrics): Call row_hash, instead of computing the
6596 * dispnew.c (verify_row_hash): Call row_hash for computing the
6597 hash code of a row, instead of duplicating code from xdisp.c.
6599 * dispextern.h (row_hash): Add prototype.
6601 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6603 * frame.c (delete_frame): Don't delete the terminal when the last

6635 * image.c (imagemagick_load_image): Fix typo.
6637 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6639 * xdisp.c (display_line): Move the call to

6707 The trivial performance wins aren't worth the portability hassles; see
6708 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6710 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6774 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6776 * xmenu.c (cleanup_widget_value_tree): New function.
6777 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
6778 calling free_menubar_widget_value_tree directly (Bug#9830).
6780 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
6782 Fix some portability problems with 'inline'.
6783 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6784 (window_box_width, window_box_left, window_box_left_offset)
6785 (window_box_right, window_box_right_offset): Declare extern.
6786 Otherwise, these inline functions do not conform to C99 and
6787 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6788 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6789 * intervals.c (adjust_intervals_for_insertion)
6790 (adjust_intervals_for_deletion): Now extern, because otherwise the
6791 extern inline functions 'offset_intervals' couldn't refer to it.
6792 (static_offset_intervals): Remove.
6793 (offset_intervals): Rewrite using the old contents of
6794 static_offset_intervals. The old version didn't conform to C99
6795 because an extern inline function contained a reference to an
6796 identifier with static linkage.
6798 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6800 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6818 (Fwindow_vscroll): Doc fix.
6819 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6820 argument, since it makes no sense to pass a live window and for
6821 consistency with window-child.

6849 (unwind_create_frame): New function (Bug#9943).
6850 (Fx_create_frame): Restructure code to be more similar to the one in
6851 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6852 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6853 Move terminal->reference_count++ just before making the frame official

6902 * xdisp.c (note_mouse_highlight): If either of
6903 previous/next-single-property-change returns nil, treat that as
6904 the beginning or the end of the buffer. (Bug#9955)

6932 Rename cover_string to disp_string.
6934 2011-11-01 Martin Rudalics <rudalics@gmx.at>

6965 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6967 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6968 so that this new function doesn't get optimized away by a
6969 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6971 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6973 * frame.h (MOUSE_HL_INFO): Remove excess parens.

7029 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7031 (w32font_open_internal, compute_metrics):
7032 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7033 instead of calling the "wide" APIs directly.
7035 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

7051 non-NULL, regardless of GNUTLS_INITSTAGE.
7052 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7053 an error. Set process slots as soon as we allocate them.

7099 current character, check also for next_en_type being WEAK_EN.
7100 (bidi_resolve_weak): Don't enter the expensive loop if the current
7101 position is before next_en_pos. Record the bidi type of the first
7102 non-ET, non-BN character we find, in addition to its position.
7103 (bidi_level_of_next_char): Invalidate next_en_type when
7104 next_en_pos is over-stepped.
7106 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7108 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7109 * editfns.c: Rewrite current-time-zone so that it invokes
7110 the equivalent of (format-time-string "%Z") to get the time zone name.
7111 This fixes a bug when the time zone name contains characters that
7112 need converting from the system time locale to Emacs internal format.
7113 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7114 that patch fixed format-time-string to do the conversion, but
7115 I forgot to fix current-time-zone.
7116 (format_time_string): New function, containing most of
7117 what Fformat_time_string used to contain.
7118 (Fformat_time_string): Rewrite in terms of format_time_string.
7119 This doesn't change this function's behavior.
7120 (current-time-zone): Rewrite to use format_time_string.
7121 This fixes the bug reported by Michael Schierl in
7122 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7123 Jason Rumney's 2007-06-07 change worked around this bug, but
7125 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7127 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7129 * xdisp.c (start_display): If the character at POS is displayed
7130 via a display vector, reset IT->current.dpvec_index to zero.
7131 (try_window_reusing_current_matrix): If a line ends in a display
7132 vector or the next line starts in a display vector, continue
7133 redrawing the window even though the character position of
7134 start_row was reached.
7137 2011-10-18 Chong Yidong <cyd@gnu.org>
7139 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7140 with nobreak-char-display too.
7142 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7144 Fix part 3 of bug#9771.
7145 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7146 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7147 non-neutral characters if the current character is a paragraph
7148 separator (a.k.a. Newline). This avoids running the same
7149 expensive loop twice, once when we consume the preceding newline
7150 and the other time when the line actually needs to be displayed.
7151 Avoid the loop when we see neutrals on the base embedding level
7152 following a character whose directionality is the same as the
7153 paragraph's. This avoids running the expensive loop when a line
7154 ends in a long sequence of neutrals, like control characters.
7155 Add assertion against STRONG_AL type. Slightly rearrange code
7156 that determines the type of a neutral given the first non-neutral
7158 (bidi_level_of_next_char): Set next_en_pos to zero when
7159 invalidating its info.
7161 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7163 * xdisp.c (push_display_prop): Determine whether to record string
7164 or buffer position by IT->string, not by IT->method. Allow
7165 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7166 (move_it_vertically_backward): Don't look for character position
7167 immediately after the newline when in a continuation line.
7170 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7172 * window.c (coordinates_in_window): Rewrite and delabelize
7173 vertical border check. (Bug#5357) (Bug#9618)
7175 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7177 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7178 errors in XSetWindowBorder (bug#9310).
7180 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7182 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7183 avoid crash when xmalloc overrun checking is enabled.
7185 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7187 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7188 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7189 cursor motion with <left> and <right> arrow keys.
7191 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7192 some callers set that themselves.
7194 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7196 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7197 display string and the previous row comes from the same string and
7198 is empty. (Bug#9739) (Bug#9738)
7200 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7202 * doc.c (get_doc_string): Encode file name (bug#9735).
7204 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7206 * bidi.c (bidi_level_of_next_char):
7207 * xdisp.c (get_visually_first_element): Remove old incorrect
7208 comments regarding the Unicode Line Separator character.
7210 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

7220 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7221 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7223 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7224 Some packages use them to denote characters with modifiers.
7226 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7228 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7229 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7230 matching a pp-number. Rename parameter var to var1.
7232 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7234 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7236 2011-10-08 Glenn Morris <rgm@gnu.org>
7238 * callint.c (Fcall_interactively): Give a more explicit error for the
7239 'c' case with a non-character input. (Bug#8479)
7241 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7243 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7245 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7246 lines that are hscrolled on the left.
7248 * dispnew.c (buffer_posn_from_coords): Account for a possible
7249 presence of header-line. (Bug#4426)
7251 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7253 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7254 Don't advertise functionality which we discourage or doesn't work.
7256 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7258 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7259 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7260 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7261 this makes Emacs dump core during garbage collection on rare
7262 occasions. sizeof is obviously inferior to offsetof here, so
7263 stick with offsetof.
7264 (GC_POINTER_ALIGNMENT): New macro.
7265 (mark_memory): Omit 3rd (offset) arg; caller changed.
7266 Don't assume EMACS_INT alignment is the same as pointer alignment.
7268 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7270 * keyboard.c (read_key_sequence_remapped): New var.
7271 (read_key_sequence): Compute remapping in the right buffer.
7272 (command_loop_1): Use read_key_sequence's remapping directly.
7274 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7276 * dired.c (file_name_completion): Don't expand file name.
7277 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7278 before checking file name handler.
7280 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7281 they've been requested explicitly (bug#9591).
7283 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7285 * keymap.c (Fsingle_key_description): Use make_specified_string
7286 instead of build_string to build string from push_key_description.
7289 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7291 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7292 This fixes a Y2038 bug on 64-bit hosts.
7293 * buffer.c (reset_buffer):
7294 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7295 (Fclear_buffer_auto_save_failure):
7296 Use 0, not -1, to represent an unset failure time, since time_t
7297 might not be signed.
7299 Remove dependency on glibc malloc internals.
7300 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7301 Move back here from lisp.h, but with their new implementations.
7302 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7303 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7304 * charset.c (charset_table_init): New static var.
7305 (syms_of_charset): Use it instead of xmalloc. This removes a
7306 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7307 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7308 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7309 Move back to alloc.c.
7310 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7311 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7313 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7315 * nsterm.m (windowDidResize): Call x_set_window_size only when
7316 ns_in_resize is true. Otherwise set pixelwidth/height and
7317 call change_frame_size (Bug#9628).
7319 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7321 Port --enable-checking=all to Fedora 14 x86-64.
7322 * charset.c (syms_of_charset): Also account for glibc malloc's
7323 internal overhead when calculating the initial malloc maximum.
7325 Port --enable-checking=all to Fedora 14 x86.
7326 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7328 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7329 (overrun_check_realloc, overrun_check_free):
7330 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7331 That way, xmalloc returns a properly-aligned pointer even if
7332 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7333 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7334 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7335 into account when calculating the initial malloc maximum.
7336 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7337 Move here from alloc.c, so that charset.c can use it too.
7338 Properly align; the old code wasn't right for common 32-bit hosts
7339 when configured with --enable-checking=all.
7340 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7341 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7343 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7345 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7348 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7350 * xdisp.c (compute_display_string_end): If there's no display
7351 string at CHARPOS, return -1.
7353 * bidi.c (bidi_fetch_char): When compute_display_string_end
7354 returns a negative value, treat the character as a normal
7355 character not covered by a display string. (Bug#9624)
7357 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7359 * lread.c (Fread_from_string): Fix typo in docstring.
7361 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7363 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7364 newline, reseat the iterator instead of bidi-iterating there one
7365 character at a time. (Bug#9610)
7366 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7367 TO_CHARPOS if the bidi iterator is at base embedding level.
7369 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7371 * lread.c (readevalloop): Use correct code for NBSP.
7372 (read1): Likewise. (Bug#9608)
7374 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7376 * dbusbind.c (Fdbus_register_signal): When service is not
7377 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7379 2011-09-25 Glenn Morris <rgm@gnu.org>
7381 * buffer.c (truncate-lines): Doc fix.
7383 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7385 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7386 (Fset_window_next_buffers): Doc fix.
7388 2011-09-24 Glenn Morris <rgm@gnu.org>
7390 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7392 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7394 Fix minor problems found by static checking.
7395 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7396 * indent.c (Fvertical_motion): Fix == vs = typo.
7398 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7400 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7401 Default value is now t. Doc fix.
7403 * indent.c (Fvertical_motion): Compute and apply the overshoot
7404 logic when moving up, not only when moving down. Fix the
7405 confusing name and values of the it_overshoot_expected variable;
7406 logic changes accordingly. (Bug#9254) (Bug#9549)
7408 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7409 CHARPOS is covered by a display string which includes newlines.
7410 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7411 is covered by a display string with embedded newlines.
7413 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7415 * dbusbind.c (Fdbus_register_signal): Add match rule to
7416 Vdbus_registered_objects_table. (Bug#9581)
7417 (Fdbus_register_method, Vdbus_registered_objects_table):
7420 2011-09-24 Jim Meyering <meyering@redhat.com>
7422 do not ignore write error for any output size
7423 The previous change was incomplete.
7424 While it makes emacs --batch detect the vast majority of stdout
7425 write failures, errors were still ignored whenever the output size is
7426 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7427 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7428 && echo FAIL: ignored write error
7429 FAIL: ignored write error
7430 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7431 && echo FAIL: ignored write error
7432 FAIL: ignored write error
7433 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7435 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7437 * emacs.c (Fkill_emacs): In noninteractive mode exit
7438 non-successfully if a write error occurred on stdout. (Bug#9574)
7440 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7442 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7445 * dispextern.h (struct it): Update the comment documenting what
7448 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7450 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7451 a display string, extend search for cursor position to end of row.
7452 (find_row_edges): If the row ends in a newline from a display
7453 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7454 Handle the case of a display string with multiple newlines.
7455 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7456 non-empty line. Fixes confusing cursor motion with arrow keys at
7457 the beginning of a line that starts with whitespace.
7459 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7461 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7464 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7466 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7469 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7471 * xdisp.c (display_line): Record maximum and minimum buffer
7472 positions even if no glyphs were produced (e.g., by a zero-width
7473 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7474 buffer positions that will be removed from the glyph row because
7476 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7477 column is beyond frame width: don't subtract 1 "pixel" when
7478 computing width of the stretch.
7479 (reseat_at_next_visible_line_start): Undo the change made on
7480 2011-09-17 that saved paragraph information and restored it after
7481 the call to `reseat'. (Bug#9545)
7483 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7485 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7486 and turn window cursor on if cleared (Bug#9415).
7488 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7490 * search.c (boyer_moore): Take unibyte characters from pattern
7491 literally. (Bug#9458)
7493 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7495 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7497 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7499 Fix minor problem found by static checking.
7500 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7501 initialized, to pacify gcc -Wuninitialized.
7503 * fileio.c: Report proper errno when syscall falls.
7504 (Finsert_file_contents): Save and restore errno,
7505 so that report_file_error outputs the correct diagnostic.
7506 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7508 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7510 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7512 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7514 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7515 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7517 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7519 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7520 about the current paragraph and restore it after the call to reseat.
7522 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7523 (bidi_find_paragraph_start): Search back for paragraph beginning
7524 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7525 (bidi_move_to_visually_next): Only trigger paragraph-related
7526 computations when the last character is a newline or at EOB, not
7527 just any NEUTRAL_B. (Bug#9470)
7529 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7530 truncated lines if point is covered by a display string. (Bug#9524)
7532 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7534 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7535 (cons_to_x_long): New function.
7536 (lisp_data_to_selection_data): Use it. Correct the test for
7537 short-versus-long data; it was negated. Break out of vector
7538 loop, for efficiency, when a long datum is discovered.
7540 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7542 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7544 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7546 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7547 GCC PR/17406) by declaring this function with external scope.
7549 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7551 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7552 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7554 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7556 * editfns.c (Fformat): Correctly handle text properties on "%%".
7558 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7560 * xterm.c (x_draw_composite_glyph_string_foreground):
7561 * w32term.c (x_draw_composite_glyph_string_foreground):
7562 * term.c (encode_terminal_code):
7563 * composite.c (composition_update_it, get_composition_id):
7564 * xdisp.c (get_next_display_element)
7565 (fill_composite_glyph_string): Add comments about special meaning
7566 of TAB characters in a composition.
7568 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7570 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7571 This occurs when processing a multibyte format.
7572 Problem reported by Wolfgang Jenker.
7574 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7576 * xdisp.c (try_cursor_movement): Only check for exact match if
7577 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7579 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7581 Remove unused external symbols.
7582 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7583 * xdisp.c (calc_pixel_width_or_height): Now static.
7584 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7585 * indent.c (check_display_width):
7586 * w32term.c: Fix comment to match code.
7587 * xterm.c, xterm.h (x_catching_errors): Remove.
7589 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7591 * xselect.c: Use signed conversions more consistently (Bug#9498).
7592 (selection_data_to_lisp_data): Assume incoming selection data are
7593 signed integers, not unsigned. This is to be consistent with
7594 outgoing selection data, which was modified to use signed integers
7595 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7596 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7597 expects long, not unsigned long.
7599 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7601 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7602 computation of loop end. Reported by Johan Bockgård
7605 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7607 * frame.c (Fother_visible_frames_p): Function deleted.
7609 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7611 * indent.c (compute_motion): Process display vector front to back
7612 rather than the other way around. (Bug#2496)
7614 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7616 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7618 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7620 * minibuf.c (Fread_from_minibuffer): Doc fix.
7622 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7624 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7625 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7627 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7629 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7630 value for non-existent files.
7632 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7634 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7635 set its "size" to -1. This will set the modtime_size field of
7636 the corresponding buffer to -1, which is what
7637 verify-visited-file-modtime expects for files that do not exist.
7640 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7642 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7644 * lisp.h: ... from here. push_key_description is no longer
7645 defined in keyboard.c, so its declaration should not be in
7646 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7647 logically belongs with push_key_description.
7649 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7651 * buffer.h: Include <sys/types.h> instead of <time.h>.
7652 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7653 Problem reported by Herbert J. Skuhra.
7655 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7657 * xml.c (parse_region): Make the parsing work for
7658 non-comment-starting XML files again (bug#9144).
7660 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7662 * image.c (gif_load): Fix calculation of bottom and right corner.
7665 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7667 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7668 redisplay in small windows.
7670 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7672 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7674 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7676 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7677 Operate on live windows only.
7679 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7681 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7683 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7685 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7686 only under bidi iteration.
7688 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7690 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7692 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7694 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7695 Without this fix, the command to link temacs failed due to an
7696 undefined symbol __builtin_isnan. This is because
7697 /usr/include/iso/math_c99.h #defines isnan(x) to
7698 __builtin_isnan(x), but the bundled gcc, which identifies itself
7699 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7701 * floatfns.c (isnan): #undef, and then #define to a clone of
7703 (Fisnan): Always define, since it's always available now.
7704 (syms_of_floatfns): Always define isnan at the Lisp level.
7706 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7708 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7710 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7712 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7713 The previous code assumed that file offsets (off_t values) fit in
7714 EMACS_INT variables, which is not true on typical 32-bit hosts.
7715 The code messed up by falsely reporting buffer overflow in cases
7716 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7717 when "big" contains more than 2**29 bytes, even though this
7718 inserts just one byte and does not overflow the buffer.
7719 (Finsert_file_contents): Store file offsets as off_t
7720 values, not as EMACS_INT values. Check for overflow when
7721 converting between EMACS_INT and off_t. When checking for
7722 buffer overflow or for overlap, take the offsets into account.
7723 Don't use EMACS_INT for small values where int suffices.
7724 When checking for overlap, fix a typo: ZV was used where
7725 ZV_BYTE was intended.
7726 (Fwrite_region): Don't assume off_t fits into 'long'.
7727 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7729 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7731 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7733 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7735 sprintf-related integer and memory overflow issues (Bug#9412).
7737 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7738 (esprintf, exprintf, evxprintf): New functions.
7739 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7740 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7741 (modify_event_symbol): Do not assume that the length of
7742 name_alist_or_stem is safe to alloca and fits in int.
7743 (Fexecute_extended_command): Likewise for function name and binding.
7744 (Frecursion_depth): Wrap around reliably on integer overflow.
7745 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7746 since some callers pass EMACS_INT values.
7747 (Fsingle_key_description): Don't crash if symbol name contains more
7748 than MAX_ALLOCA bytes.
7749 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7750 (get_minibuffer): Arg is now EMACS_INT, not int.
7751 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7752 (esprintf, exprintf, evxprintf): New decls.
7753 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7755 * dbusbind.c (signature_cat): New function.
7756 (xd_signature, Fdbus_register_signal):
7757 Do not overrun buffer; instead, report string overflow.
7759 * dispnew.c (add_window_display_history): Don't overrun buffer.
7760 Truncate instead; this is OK since it's just a log.
7762 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7763 even if the time zone offset is outlandishly large.
7764 Don't mishandle offset == INT_MIN.
7766 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7767 when creating daemon; the previous buffer-overflow check was incorrect.
7769 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7770 which has the guts of the old verror function.
7772 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7773 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7775 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7776 (font_unparse_xlfd): Don't blindly alloca long strings.
7777 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7778 fits in int, when using sprintf. Use single snprintf to count
7779 length of string rather than counting it via multiple sprintfs;
7780 that's simpler and more reliable.
7781 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7782 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7783 sprintf, in case result does not fit in int.
7785 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7786 (fontset_from_font): Print it.
7788 * frame.c (tty_frame_count): Now printmax_t, not int.
7789 (make_terminal_frame, set_term_frame_name): Print it.
7790 (x_report_frame_params): In X, window IDs are unsigned long,
7791 not signed long, so print them as unsigned.
7792 (validate_x_resource_name): Check for implausibly long names,
7793 and don't assume name length fits in 'int'.
7794 (x_get_resource_string): Don't blindly alloca invocation name;
7795 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7798 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7799 (xg_check_special_colors, xg_set_geometry):
7800 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7802 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7803 Use esprintf, not sprintf, in case result does not fit in int.
7805 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7806 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7807 it as a large positive number.
7808 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7809 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7811 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7812 in case result does not fit in int.
7814 * print.c (float_to_string): Detect width overflow more reliably.
7815 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7816 buffer overrun. Don't assume list length fits in 'int'. Treat
7817 print length of 0 as 0, not as infinity; to be consistent with other
7818 uses of print length in this function. Don't overflow print length
7819 index. Don't assume hash table size fits in 'long', or that
7820 vectorlike size fits in 'unsigned long'.
7822 * process.c (make_process): Use printmax_t, not int, to format
7823 process-name gensyms.
7825 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7827 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7828 to avoid potential buffer overrun.
7830 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7831 if X resource line is longer than 512 bytes.
7833 * xfns.c (x_window): Make sprintf buffer a bit bigger
7834 to avoid potential buffer overrun.
7836 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7838 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7840 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7842 Integer overflow fixes for scrolling, etc.
7843 Without these, Emacs silently mishandles large integers sometimes.
7844 For example, "C-u 4294967297 M-x recenter" was treated as if
7845 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7847 * xdisp.c (try_window_id): Check Emacs fixnum range before
7848 converting to 'int'.
7850 * window.c (window_scroll_line_based, Frecenter):
7851 Check that an Emacs fixnum is in range before assigning it to 'int'.
7852 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7853 values converted from Emacs fixnums.
7854 (Frecenter): Don't wrap around a line count if it is out of 'int'
7855 range; instead, treat it as an extreme value.
7856 (Fset_window_configuration, compare_window_configurations):
7857 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7859 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7860 that can exceed INT_MAX. Check that EMACS_INT value is in range
7861 before assigning it to the (possibly-narrower) index.
7862 (match_limit): Don't assume that a fixnum can fit in 'int'.
7864 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7867 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7868 (Fvertical_motion): Don't wrap around LINES values that don't fit
7869 in 'int'. Instead, treat them as extreme values. This is good
7870 enough for windows, which can't have more than INT_MAX lines anyway.
7872 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7874 * Require libxml/parser.h to avoid compilation warning.
7876 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7878 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7879 since this reportedly can destroy thread storage.
7881 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7883 * syntax.c (find_defun_start): Update all cache variables if
7884 exiting early (Bug#9401).
7886 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7888 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7890 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7891 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7892 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7894 * term.c (tty_append_glyph): New function.
7895 (produce_stretch_glyph): Static function and its prototype deleted.
7897 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7900 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7902 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7903 when checking :margin (Bug#9390).
7904 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7905 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7906 so that the name doesn't mislead. All uses changed.
7908 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7910 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7913 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7915 * xdisp.c (move_it_to): Don't bail out early when reaching
7916 position beyond to_charpos, if we are scanning backwards.
7917 (move_it_vertically_backward): When DY == 0, make sure we get to
7918 the first character in the line after the newline.
7920 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7922 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7923 (ccl_driver): Do not generate an out-of-range pointer.
7924 (Fccl_execute_on_string): Remove unnecessary check for
7925 integer overflow, noted by Stefan Monnier in
7926 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7927 Remove a FIXME that didn't need fixing.
7928 Simplify the newly-introduced buffer reallocation code.
7930 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7932 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7934 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7936 Integer and memory overflow issues (Bug#9196).
7938 * doc.c (get_doc_string): Rework so that
7939 get_doc_string_buffer_size is the actual buffer size, rather than
7940 being 1 less than the actual buffer size; this makes xpalloc more
7943 * image.c (x_allocate_bitmap_record, cache_image):
7944 * xselect.c (Fx_register_dnd_atom):
7945 Simplify previous changes by using xpalloc.
7947 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7948 since either will do and ptrdiff_t is convenient with xpalloc.
7950 * charset.c (charset_table_size)
7951 (struct charset_sort_data.priority): Now ptrdiff_t.
7952 (charset_compare): Don't overflow if priorities differ greatly.
7953 (Fsort_charsets): Don't assume list length fits in int.
7954 Check for size-calculation overflow when allocating sort data.
7955 (syms_of_charset): Allocate an initial charset table that is
7956 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7958 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7960 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7961 The actual value is always <= INT_MAX, and leaving it unsigned made
7962 overflow checking harder.
7964 * dispextern.h (struct glyph_matrix.rows_allocated)
7965 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7966 with xpalloc. The values are still always <= INT_MAX.
7968 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7970 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7971 (SAFE_NALLOCA): New macro.
7973 * region-cache.c (struct boundary.pos, find_cache_boundary)
7974 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7975 (set_cache_region, invalidate_region_cache)
7976 (revalidate_region_cache, know_region_cache, region_cache_forward)
7977 (region_cache_backward, pp_cache):
7978 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7979 so that ptrdiff_t * can be passed to xpalloc.
7980 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7981 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7982 (pp_cache): Don't assume cache_len fits in int.
7983 * region-cache.h: Adjust extern decls to match.
7985 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7986 EMACS_INT, since either will do, for xpalloc.
7988 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7989 (xnmalloc, xnrealloc, xpalloc): New functions.
7991 * bidi.c (bidi_shelve_header_size): New constant.
7992 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7993 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7995 * bidi.c (bidi_cache_shrink):
7996 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7998 Don't update size of array until after memory allocation succeeds,
7999 because xmalloc/xrealloc may not return.
8000 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8001 now that we have proper integer overflow checking.
8002 (record_overlay_string, overlay_strings): Catch overflows when
8003 calculating size of overlay_str_buf.
8005 * callproc.c (Fcall_process): Check for size overflow when
8006 calculating size of args2.
8007 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8008 Normally we prefer signed values, but sticking with ptrdiff_t would
8009 require adding more-complicated checks.
8011 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8012 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8013 Redo buffer-overflow calculations to avoid integer overflow.
8014 Add a FIXME comment where memory seems to be over-allocated.
8016 * character.c (Fstring): Check for size-calculation overflow.
8018 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8019 unnecessary integer overflow. Check for size overflow.
8020 (encode_coding_object): Don't update size until xmalloc succeeds.
8022 * composite.c (get_composition_id): Check for overflow in glyph
8023 length calculations.
8025 Integer and memory overflow fixes for display code.
8026 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8027 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8028 (scrolling_window): Check for overflow in size calculations.
8029 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8030 Don't assume glyph table len fits in int.
8031 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8032 (row_table_size): Now ptrdiff_t, not int.
8033 (scrolling_window): Avoid overflow in size calculations.
8034 Don't update size until allocation succeeds.
8035 * fns.c (concat): Check for overflow in size calculations.
8036 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8037 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8038 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8040 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8041 (get_doc_string): Check for size calculation overflow.
8042 Don't update size until allocation succeeds.
8043 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8044 EMACS_INT, where ptrdiff_t will do.
8045 (Fsubstitute_command_keys): Check for string overflow.

8049 (message_length): Now ptrdiff_t, not int.
8050 (Fmessage_box): Don't update size until allocation succeeds.
8051 Don't assume message length fits in int.
8052 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8054 * emacs.c (main): Do not reallocate argv, since there is a null at
8055 the end that can be overwritten, and this way there's no need to
8056 worry about size-calculation overflow.
8057 (sort_args): Check for size-calculation overflow.
8059 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8061 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8063 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8064 (x_set_scroll_bar_width, x_figure_window_size):
8065 Check for integer overflow.
8066 (x_set_alpha): Do not assume XINT fits in int.
8068 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8069 This is for the members text_lines, text_cols, total_lines, total_cols,
8070 where the system imposes an 'int' limit.
8072 * fringe.c (Fdefine_fringe_bitmap):
8073 Don't update size until alloc works.
8075 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8076 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8078 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8079 Check for size-calculation overflow.
8080 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8081 do, as we prefer signed integers.
8082 (id_to_widget.max_size, id_to_widget.used)
8083 (xg_store_widget_in_map, xg_remove_widget_from_map)
8084 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8085 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8086 Use and return ptrdiff_t, not int.
8087 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8088 * gtkutil.h: Change prototypes to match the above.
8090 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8091 are duplicate now that they've been promoted to lisp.h.
8092 (x_allocate_bitmap_record, x_alloc_image_color)
8093 (make_image_cache, cache_image, xpm_load):
8094 Don't update size until alloc is done.

8097 Check for size calculation overflow.
8098 (ct_colors_allocated_max): New constant.
8099 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

8104 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8105 Use ptrdiff_t, not int, to count maps.
8106 (read_char_minibuf_menu_prompt): Check for overflow in size
8107 calculations. Don't update size until allocation succeeds.

8119 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8121 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8122 Now ptrdiff_t, not int.
8123 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8124 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.

8135 (Fset_match_data): Don't assume list lengths fit in 'int'.
8137 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8138 for command line length. Do not attempt to address one before the
8139 beginning of an array, as that's not portable.

8142 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8144 (encode_terminal_code, calculate_costs): Check for size
8145 calculation overflow.

8167 Use ptrdiff_t, not int, for sizes.
8168 (Finternal_make_lisp_face, cache_face):
8169 Check for size calculation overflow.
8170 (cache_face): Treat size calculation overflows as if they were
8171 memory exhaustion (the usual treatment), rather than aborting.
8173 * xfns.c (x_encode_text, x_set_name_internal)
8174 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8175 sizes, since they can exceed INT_MAX in size. Check for size

8185 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8186 (X_LONG_MIN): New macros.
8187 Use them to make the following changes clearer.
8188 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8189 This change doesn't affect the value now, but it may help remind
8190 future maintainers not to raise the value too much later.
8191 (SELECTION_QUANTUM): Remove, replacing with ...
8192 (selection_quantum): ... new function, which avoids overflow.
8194 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8195 assumption that selection length fits in 'int'.
8196 (x_reply_selection_request, x_handle_selection_request)
8197 (x_get_window_property, receive_incremental_selection)
8198 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8199 (lisp_data_to_selection_data, clean_local_selection_data):
8200 Use ptrdiff_t, not int, to record length of selection.
8201 (x_reply_selection_request, x_get_window_property)
8202 (receive_incremental_selection, x_property_data_to_lisp):
8203 Redo calculations to avoid overflow.
8204 (x_reply_selection_request): When sending hint, ceiling it at
8205 X_LONG_MAX rather than relying on wraparound overflow to send
8207 (x_get_window_property, receive_incremental_selection)
8208 (lisp_data_to_selection_data, x_property_data_to_lisp):
8209 Check for size-calculation overflow.
8210 (x_get_window_property, receive_incremental_selection)
8211 (lisp_data_to_selection_data, Fx_register_dnd_atom):
8212 Don't store size until memory allocation succeeds.
8213 (x_get_window_property): Plug memory leak on memory exhaustion.
8214 Don't double-block input; malloc is safe here. Don't assume 2**34
8215 - 4 fits in unsigned long. Add an xassert to check
8216 XGetWindowProperty overflow. Be more careful about overflow
8217 calculations, and distinguish size from memory overflow better.
8218 (receive_incremental_selection): When tracing, don't assume
8219 unsigned int is less than INT_MAX.
8220 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8221 harmful) conversions of unsigned short to int.
8222 (lisp_data_to_selection_data): Don't assume that integers
8223 in the range -65535 through -1 fit in an X unsigned short.
8224 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8225 result parameters unless successful. Rely on cons_to_unsigned
8226 to report problems with elements; the old code wasn't right anyway.
8227 (x_check_property_data): Check for int overflow; we cannot use
8228 a wider type due to X limits.
8229 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8231 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8233 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8234 (x_term_init): Check for size calculation overflow.
8235 (x_color_cells): Don't store size until memory allocation succeeds.
8236 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
8237 Don't assume alloca size is less than MAX_ALLOCA.
8238 (x_term_init): Don't assume length fits in int (sprintf is limited
8241 Use ptrdiff_t for composition IDs.

8260 * image.c (xpm_get_color_table_h):
8261 * lisp.h (hash_lookup, hash_put):
8262 * minibuf.c (Ftest_completion):
8263 Use ptrdiff_t for hash table indexes, not int (which is too
8264 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8265 32-bit --with-wide-int hosts).
8267 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8268 Add a FIXME comment about memory leaks.
8269 (syms_of_charset): Don't assume xmalloc returns.
8271 Don't assume that stated character widths fit in int.
8272 * character.c (Fchar_width, c_string_width, lisp_string_width):
8273 * character.h (CHAR_WIDTH):
8274 * indent.c (MULTIBYTE_BYTES_WIDTH):
8275 Use sanitize_char_width to avoid undefined and/or bad behavior
8276 with outlandish widths.
8277 * character.h (sanitize_tab_width): Rename from sanitize_width,
8278 now that we have two such functions. All uses changed.
8279 (sanitize_char_width): New inline function.
8281 Don't assume that tab-width fits in int.
8282 * character.h (sanitize_width): New inline function.
8283 (SANE_TAB_WIDTH): New macro.
8284 (ASCII_CHAR_WIDTH): Use it.
8285 * indent.c (sane_tab_width): Remove. All uses replaced by
8286 SANE_TAB_WIDTH (current_buffer).
8287 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
8289 * fileio.c: Integer overflow issues with file modes.
8290 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
8292 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

8296 * xterm.c: Don't go over XClientMessageEvent limit.
8297 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8298 (x_send_scroll_bar_event): Likewise. Check that the size does not
8299 exceed limits imposed by XClientMessageEvent, as well as the usual
8300 ptrdiff_t and size_t limits.
8302 * keyboard.c: Overflow, signedness and related fixes.
8303 (make_lispy_movement): Use same integer type in forward decl
8304 that is used in the definition.
8305 (read_key_sequence, keyremap_step):
8306 Change bufsize argument back to int, undoing my 2011-03-30 change.
8307 We prefer signed types, and int is wide enough here.
8308 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8309 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8310 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8311 length, not size_t. Use ptrdiff_t for index, not int.
8312 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8313 possibility of integer overflow.
8315 Overflow, signedness and related fixes for images.
8317 * dispextern.h (struct it.stack[0].u.image.image_id)
8318 (struct_it.image_id, struct image.id, struct image_cache.size)

8324 * nsmenu.m (update_frame_tool_bar):
8325 * xdisp.c (calc_pixel_width_or_height):
8326 * xfns.c (image_cache_refcount):
8327 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8328 on typical 64-bit hosts.
8330 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8331 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
8332 Omit unnecessary casts to int.

8334 when the callers expect that.
8335 (image_ascent): Redo ascent calculation to avoid int overflow.
8336 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8337 (lookup_image): Remove unnecessary tests.
8338 (xbm_image_p): Locals are now of int, not EMACS_INT,
8339 since parse_image_check makes sure they fit into int.
8340 (png_load, gif_load, svg_load_image):
8341 Prefer int to unsigned where either will do.
8342 (tiff_handler): New function, combining the cores of the
8343 old tiff_error_handler and tiff_warning_handler.
8344 This function is rewritten to use vsnprintf and thereby avoid
8345 stack buffer overflows. It uses only the features of vsnprintf
8346 that are common to both POSIX and native Microsoft.
8347 (tiff_error_handler, tiff_warning_handler): Use it.
8348 (tiff_load, gif_load, imagemagick_load_image):
8349 Don't assume :index value fits in 'int'.
8350 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8351 (imagemagick_load_image): Check that crop parameters fit into
8352 the integer types that MagickCropImage accepts. Don't assume
8353 Vimagemagick_render_type has a nonnegative value. Don't assume
8354 size_t fits in 'long'.
8355 (gs_load): Use printmax_t to print the widest integers possible.
8356 Check for integer overflow when computing image height and width.
8358 2011-08-26 Eli Zaretskii <eliz@gnu.org>
8360 * xdisp.c (redisplay_window): Don't force window start if point
8361 will be invisible in the resulting window. (Bug#9324)
8363 2011-08-25 Eli Zaretskii <eliz@gnu.org>
8365 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8366 the display spec is of the form `(space ...)'.
8367 (handle_display_spec): Return the value returned by
8368 handle_single_display_spec, not just 1 or zero.
8369 (handle_single_display_spec): If the display spec is of the form
8370 `(space ...)', and specifies display in the text area, return 2
8372 (try_cursor_movement): Check for the need to scroll more
8373 accurately, and prefer exact match for point under bidi.
8374 Don't advance `row' beyond the last row of the window.
8376 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8377 into disp_prop; all users changed.
8379 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8380 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8381 for the text covered by the display property.
8383 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8385 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8391 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8392 buffers, return left-to-right.
8393 (set_cursor_from_row): Consider candidate row a win if its glyph
8394 represents a newline and point is on that newline. Fixes cursor
8395 positioning on the newline at EOL of R2L text within L2R
8396 paragraph, and vice versa.
8397 (try_cursor_movement): Check continued rows, in addition to
8398 continuation rows. Fixes unwarranted scroll when point enters a
8399 continued line of R2L text within an L2R paragraph, or vice versa.
8400 (cursor_row_p): Consider the case of point being equal to
8401 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8402 from the end of a short line to the beginning of a continued line
8403 of R2L text within L2R paragraph.
8404 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8405 composed characters.
8407 * bidi.c (bidi_check_type): Use xassert.
8408 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8411 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8413 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
8416 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8418 * nsfont.m (ns_otf_to_script): Fix typo.
8420 2011-08-22 Kenichi Handa <handa@m17n.org>
8422 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8423 extra slot even if the purpose is char-code-property-table.
8425 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8427 * xdisp.c (redisplay_window): When computing centering_position,
8428 account for the height of the header line. (Bug#8874)
8430 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8431 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8432 candidate is selected by the mouse, and that candidate has a
8433 composed character under the mouse.
8435 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8436 coordinates reported by pos-visible-in-window-p for a composed
8437 character in column zero.
8439 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8441 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8443 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8445 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8446 consider it a hit if to_charpos is anywhere in the range of the
8447 composed buffer positions.
8449 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8451 * image.c (gif_load): Don't assume that each subimage has the same
8452 dimensions as the base image. Handle disposal method that is
8453 "undefined" by the gif spec (Bug#9335).
8455 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8457 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8458 (Fcondition_case): Document `debug' symbol in error handler.
8460 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8462 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8463 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8464 from an Org mode buffer to a Speedbar frame.
8466 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8467 a composition, take its buffer position from IT->cmp_it.charpos.
8468 Fixes cursor positioning at the beginning of a line that begins
8469 with a composed character.
8471 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8473 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8474 character bidirectional type, use STRONG_L instead. Fixes crashes
8475 in a buffer produced by `describe-categories'.
8477 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8478 members before the level stack, so they would be saved and
8479 restored when copying iterator state. Fixes incorrect reordering
8480 around TABs covered by display properties.
8482 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8484 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
8486 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
8488 * eval.c (internal_condition_case, internal_condition_case_1)
8489 (internal_condition_case_2, internal_condition_case_n):
8490 Remove unnecessary aborts (Bug#9081).
8492 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8494 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8495 has no `load' handler, try opening the file locally. (Bug#9311)
8497 2011-08-16 Ken Brown <kbrown@cornell.edu>
8499 * gmalloc.c: Expand comment.
8501 2011-08-16 Eli Zaretskii <eliz@gnu.org>
8503 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
8504 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8506 2011-08-16 Ken Brown <kbrown@cornell.edu>
8508 Fix memory allocation problems in Cygwin build (Bug#9273).
8510 * unexcw.c ( __malloc_initialized): Declare external variable.
8511 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8513 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8515 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8517 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8519 [CYGWIN] (special_realloc): New function.
8520 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8521 requests to realloc storage in the static heap.

8532 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8534 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8536 * chartab.c: Improve commentary for the uniprop_table API.
8538 * bidi.c (bidi_paragraph_init): Support zero value of
8539 bidi_ignore_explicit_marks_for_paragraph_level.
8540 (bidi_initialize): Use uniprop_table instead of including
8541 biditype.h and bidimirror.h.
8543 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8544 coordinates of the iterator when restoring from ppos_it.
8547 2011-08-14 Kenichi Handa <handa@m17n.org>
8549 * process.c (create_process): Call setup_process_coding_systems
8550 after the pid of the process is set to -1 (Bug#8162).
8552 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8554 * xdisp.c (move_it_in_display_line_to): Don't invoke
8555 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8556 ppos_it. Fixes vertical cursor motion when line beginning is
8557 covered by an image. (Bug#9296)
8559 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8561 * nsterm.h (ns_run_ascript): Declare.
8562 (NSAPP_DATA2_RUNASSCRIPT): Define.
8564 * nsfns.m (as_script, as_result, as_status): New static variables.
8565 (ns_run_ascript): New function.
8566 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8567 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8568 the event loop. Get status from as_status (Bug#7276).
8570 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8571 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8572 the event loop (Bug#7276).
8574 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8576 * gnutls.c (QCgnutls_bootprop_priority)
8577 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8578 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)

8581 (QCgnutls_bootprop_verify_hostname_error)
8582 (QCgnutls_bootprop_callbacks_verify): Rename from
8583 Qgnutls_bootprop_..., all uses changed.
8585 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8588 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8590 * xfaces.c (Qframe_set_background_mode): Now static.
8591 * dispextern.h (Qframe_set_background_mode): Remove decl.
8593 * process.c (Fnetwork_interface_info): Declare local only if needed.
8595 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8597 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8598 (Fnetwork_interface_list): Allocate in increments of bytes instead
8599 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8600 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8602 (struct ifflag_def): notrailers is smart on OSX.
8603 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8604 Get hardware address with getifaddrs if available.
8606 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8608 * xdisp.c (iterate_out_of_display_property): xassert that
8609 IT->position is set to within IT->object's boundaries. Break from
8610 the loop as soon as EOB is reached; avoids infloops in redisplay
8611 when IT->position is set up wrongly due to some bug.
8612 Set IT->current to match the bidi iterator unconditionally.
8613 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8614 entry. Force push_it to save on the stack the current
8615 buffer/string position, to be restored by pop_it. Fix flags in
8616 the iterator structure wrt the object coming from a display
8617 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8618 properties. (Bug#9284)
8620 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8622 * fontset.c (fontset_get_font_group): Add proper type checks.
8625 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

8628 and LC_VERSION_MIN_MACOSX.
8629 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8630 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8632 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8634 * xdisp.c (forward_to_next_line_start): Allow to use the
8635 no-display-properties-and-no-overlays under bidi display.
8636 Set disp_pos in the bidi iterator to avoid searches for display
8637 properties and overlays.
8639 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8641 * editfns.c (Fset_time_zone_rule): Document relationship with the
8644 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8645 the font entity extracted from the cache (Bug#8109).
8647 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8649 * composite.c (autocmp_chars): Don't reset point. That is done by
8650 restore_point_unwind (Bug#5984).
8652 2011-08-07 Juri Linkov <juri@jurta.org>
8654 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8655 to show the arg `TIME' instead of `TIMEVAL'.
8657 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8659 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8660 display property strides EOL and includes a newline, as in
8661 longlines-mode. (Bug#9254)
8662 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8663 word-wrap under bidirectional display. (Bug#9224)
8665 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8666 is non-zero, even if the data buffer is NULL. Fixes a crash in
8667 vertical-motion with longlines-mode. (Bug#9254)
8669 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8671 * bidi.c <bidi_cache_total_alloc>: Now static.
8672 (bidi_initialize): Initialize bidi_cache_total_alloc.
8674 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8677 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8678 amount allocated this far in `bidi_cache_total_alloc'.
8679 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8680 non-zero, only free the data buffer without restoring the cache
8681 contents. All callers changed.
8683 * dispextern.h (bidi_unshelve_cache): Update prototype.
8685 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8686 (move_it_in_display_line, move_it_to)
8687 (move_it_vertically_backward, move_it_by_lines): Replace the call
8688 to xfree to an equivalent call to bidi_unshelve_cache.
8689 (move_it_in_display_line_to): Fix logic of returning
8690 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8692 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8694 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8695 came from a string character with a `cursor' property. (Bug#9229)
8697 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8699 * Makefile.in (LIB_PTHREAD): New variable.
8700 (LIBES): Add LIB_PTHREAD (Bug#9216).
8702 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8703 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8705 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8707 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8709 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8711 * xterm.c (x_find_topmost_parent): New function.
8712 (x_set_frame_alpha): Find topmost parent window with
8713 x_find_topmost_parent and set the property there also (bug#9181).
8714 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8716 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8718 * callproc.c (Fcall_process): Avoid vfork clobbering
8719 the local vars buffer, coding_systems, current_dir.
8721 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8723 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8725 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8727 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8728 so that it is not optimized away.
8730 * xdisp.c (compute_display_string_pos): Remove unused local.
8732 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8734 Fix slow cursor motion and scrolling in large buffers with
8735 selective display, like Org Mode buffers. (Bug#9218)
8737 * dispextern.h (struct bidi_it): New member disp_prop_p.
8739 * xdisp.c: Remove one-slot cache of display string positions.
8740 (compute_display_string_pos): Accept an additional argument
8741 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8742 for a display string or property. If found, set DISP_PROP_P
8745 * bidi.c (bidi_fetch_char): Accept an additional argument
8746 DISP_PROP_P, and pass it to compute_display_string_pos.
8747 Only handle text covered by a display string if DISP_PROP_P is returned
8748 non-zero. All callers of bidi_fetch_char changed.
8750 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8752 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8754 2010-12-03 Don March <don@ohspite.net>
8756 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8757 last character M-[char] is translated to ESC [char] (bug#7541).
8759 2011-08-02 Kenichi Handa <handa@m17n.org>
8761 * lisp.h (uniprop_table): Extern it.
8763 * chartab.c (uniprop_table): Make it non-static.
8765 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8767 * xdisp.c (forward_to_next_line_start): Accept additional argument
8768 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8770 (reseat_at_next_visible_line_start): Use the bidi iterator state
8771 returned by forward_to_next_line_start to restore the state of
8772 it->bidi_it after backing up to previous newline. (Bug#9212)
8774 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8776 * regex.c (re_comp): Protoize.
8777 (re_exec): Fix return type.
8778 (regexec): Fix type of `ret'. (Bug#9203)
8780 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8782 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8783 This is needed if max-image-size is a floating-point number.
8785 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8787 * print.c (print_object): Print empty symbol as ##.
8789 * lread.c (read1): Read ## as empty symbol.
8791 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8793 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8794 setting frame foreground color (Bug#9175).
8795 (x_set_background_color): Likewise.
8797 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8798 contents (Bug#9176).
8799 (EmacsTooltip -init): Remove bezels and add shadows to
8802 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8803 or scroll bar (Bug#8470).
8805 * nsfont.m (nsfont_open): Remove assignment to voffset and
8806 unnecessary vars hshink, expand, hd, full_height, min_height.
8807 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8809 * nsterm.h (nsfont_info): Remove voffset field.
8811 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8813 Implement strike-through and overline on NextStep (Bug#8863).
8815 * nsfont.m (nsfont_open): Use underline position provided by font,
8816 instead of hard-coded value of 2.
8817 (nsfont_draw): Call ns_draw_text_decoration instead.
8819 * nsterm.h: Add declaration for ns_draw_text_decoration.
8821 * nsterm.m (ns_draw_text_decoration): New function for drawing
8822 underline, overline, and strike-through.
8823 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8824 ns_draw_text_decoration. Change treatment of cursor drawing to
8825 accommodate underlining, etc.
8827 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8829 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8832 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8834 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8835 Without this fix, if a signal arrives just after memory fills up,
8836 'malloc' might be invoked reentrantly.
8838 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8839 In other words, assume that every image size is allowed, on non-X
8840 hosts. This assumption is probably wrong, but it lets Emacs compile.
8842 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8844 * regex.c (re_iswctype): Convert return values to boolean.
8846 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8848 * xdisp.c (compute_display_string_pos): Don't use cached display
8849 string position if the buffer had its restriction changed.
8852 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8854 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8856 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8858 Integer signedness and overflow and related fixes. (Bug#9079)
8860 * bidi.c: Integer size and overflow fixes.
8861 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8862 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8863 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8864 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8865 (bidi_find_other_level_edge):
8866 Use ptrdiff_t instead of EMACS_INT where either will do.
8867 This works better on 32-bit hosts configured --with-wide-int.
8868 (bidi_cache_ensure_space): Check for size-calculation overflow.
8869 Use % rather than repeated addition, for better worst-case speed.
8870 Don't set bidi_cache_size until after xrealloc returns, because it
8872 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8873 (bidi_cache_ensure_space): Also check that the bidi cache size
8874 does not exceed that of the largest Lisp string or buffer. See Eli
8875 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8877 * alloc.c (__malloc_size_t): Remove.
8878 All uses replaced by size_t. See Andreas Schwab's note
8879 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8881 * image.c: Improve checking for integer overflow.
8882 (check_image_size): Assume that f is nonnull, since
8883 it is always nonnull in practice. This is one less thing to
8884 worry about when checking for integer overflow later.
8885 (x_check_image_size): New function, which checks for integer
8886 overflow issues inside X.
8887 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8888 This removes the need for a memory_full check.
8889 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8890 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8891 (xbm_read_bitmap_data): Change locals back to 'int', since
8892 their values must fit in 'int'.
8893 (xpm_load_image, png_load, tiff_load):
8894 Invoke x_create_x_image_and_pixmap earlier,
8895 to avoid much needless work if the image is too large.
8896 (tiff_load): Treat overly large images as if
8897 x_create_x_image_and_pixmap failed, not as malloc failures.
8898 (gs_load): Use x_check_image_size.
8900 * gtkutil.c: Omit integer casts.
8901 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8902 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8904 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8906 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8907 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8908 would wrongly return t on a 64-bit host.
8910 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8911 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8912 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8913 and therefore cause GCC to emit a bogus diagnostic in some cases.
8915 * image.c: Integer signedness and overflow and related fixes.
8916 This is not an exhaustive set of fixes, but it's time to
8917 record what I've got.
8918 (lookup_pixel_color, check_image_size): Remove redundant decls.
8919 (check_image_size): Don't assume that arbitrary EMACS_INT values
8920 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8921 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8922 (tiff_load, imagemagick_load_image):
8923 Check for overflow in size calculations.
8924 (x_create_x_image_and_pixmap): Remove unnecessary test for
8925 xmalloc returning NULL; that can't happen.
8926 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8927 (xpm_color_bucket): Use better integer hashing function.
8928 (xpm_cache_color): Don't possibly over-allocate memory.
8929 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8930 (gif_memory_source):
8931 Use ptrdiff_t, not int or size_t, to record sizes.
8932 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8933 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8934 either works, as we prefer signed integers.
8935 (tiff_read_from_memory, tiff_write_from_memory):
8936 Return tsize_t, not size_t, since that's what the TIFF API wants.
8937 (tiff_read_from_memory): Don't fail simply because the read would
8938 go past EOF; instead, return a short read.
8939 (tiff_load): Omit no-longer-needed casts.
8940 (Fimagemagick_types): Don't assume size fits into 'int'.
8942 Improve hashing quality when configured --with-wide-int.
8943 * fns.c (hash_string): New function, taken from sxhash_string.
8944 Do not discard information about ASCII character case; this
8945 discarding is no longer needed.
8946 (sxhash-string): Use it. Change sig to match it. Caller changed.
8947 * lisp.h: Declare it.
8948 * lread.c (hash_string): Remove, since we now use fns.c's version.
8949 The fns.c version returns a wider integer if --with-wide-int is
8950 specified, so this should help the quality of the hashing a bit.
8952 * emacs.c: Integer overflow minor fix.
8953 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8954 Define only if GNU_LINUX.
8955 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8957 * dispnew.c: Integer signedness and overflow fixes.
8958 Remove unnecessary forward decls, that were a maintenance hassle.
8959 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8961 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8962 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8963 (prepare_desired_row, line_draw_cost):
8964 Use int, not unsigned, where either works.
8965 (save_current_matrix, restore_current_matrix):
8966 Use ptrdiff_t, not size_t, where either works.
8967 (init_display): Check for overflow more accurately, and without
8968 relying on undefined behavior.
8970 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8971 Remove, replacing with the new symbols in lisp.h. All uses changed.
8972 * fileio.c (make_temp_name):
8973 * filelock.c (lock_file_1, lock_file):
8974 * xdisp.c (message_dolog):
8975 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8976 Use pMd etc. instead.
8977 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8978 replacing the pWIDE etc. symbols removed from editfns.c.
8980 * keyboard.h (num_input_events): Now uintmax_t.
8981 This is (very slightly) less likely to mess up due to wraparound.
8984 * buffer.c: Integer signedness fixes.
8985 (alloc_buffer_text, enlarge_buffer_text):
8986 Use ptrdiff_t rather than size_t when either will do, as we prefer
8989 * alloc.c: Integer signedness and overflow fixes.
8990 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8991 (__malloc_size_t): Default to size_t, not to int.
8992 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8993 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8994 Prefer ptrdiff_t to size_t when either would do, as we prefer
8996 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8997 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8998 Now const. Initialize with values that are in range even if char
9000 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9001 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9002 These functions do the right thing with sizes > 2**32.
9003 (check_depth): Now ptrdiff_t, not int.
9004 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9005 Adjust to new way of storing sizes. Check for size overflow bugs
9007 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9008 slightly wrong anyway, as it missed one instance of
9009 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9010 (refill_memory_reserve): Omit needless cast to size_t.
9011 (mark_object_loop_halt): Mark as externally visible.
9013 * xselect.c: Integer signedness and overflow fixes.
9014 (Fx_register_dnd_atom, x_handle_dnd_message):
9015 Use ptrdiff_t, not size_t, since we prefer signed.
9016 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9017 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9018 x_dnd_atoms_size and x_dnd_atoms_length.
9020 * doprnt.c: Prefer signed to unsigned when either works.
9022 * doprnt.c (doprnt):
9024 * xdisp.c (vmessage):
9025 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9026 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9027 prefer signed arithmetic to avoid comparison confusion.
9028 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9029 but is a bit tricky.
9031 Assume freestanding C89 headers, string.h, stdlib.h.
9032 * data.c, doprnt.c, floatfns.c, print.c:
9033 Include float.h unconditionally.
9034 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9035 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9036 * regex.c: Likewise for stddef.h, string.h.
9037 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9038 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9039 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9040 (STDC_HEADERS): Remove obsolete defines.
9041 * sysdep.c: Include limits.h unconditionally.
9043 Assume support for memcmp, memcpy, memmove, memset.
9044 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9045 * regex.c (memcmp, memcpy):
9046 Remove; we assume C89 now.
9048 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9049 (__malloc_safe_bcopy): Remove; no longer needed.
9051 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9052 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9053 well either way, and we prefer signed to unsigned.
9055 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9057 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9058 closes the connection while we're reading (bug#9182).
9060 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9062 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9063 are specified (Bug#9168).
9065 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9067 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9068 Found by GCC static checking and --with-wide-int on a 32-bit host.
9070 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9072 * xdisp.c (compute_display_string_pos): Fix logic of caching
9073 previous display string position. Initialize cached_prev_pos to
9074 -1. Fixes slow-down at the beginning of a buffer.
9076 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9078 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9079 for attrs[LFACE_FONTSET_INDEX].
9081 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9083 * xml.c (parse_region): Remove unused local
9084 that was recently introduced.
9086 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9088 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9089 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9091 * xdisp.c (move_it_in_display_line_to): Record the best matching
9092 position for TO_CHARPOS while scanning the line, and restore it on
9093 exit if none of the characters scanned was an exact match.
9094 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9095 when exact match is impossible due to invisible text, and the
9096 lines are truncated.
9098 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9100 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9103 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9105 Fix a significant slow-down of cursor motion with C-n, C-p,
9106 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9107 auto-repeat under bidi redisplay in fontified buffers.
9108 * xdisp.c (compute_stop_pos_backwards): New function.
9109 (next_element_from_buffer): Call compute_stop_pos_backwards to
9110 find a suitable prev_stop when we find ourselves before
9112 (reseat): Don't look for prev_stop, as that could mean a very long
9114 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9115 <cached_disp_overlay_modiff>: Cache for last found display string
9117 (compute_display_string_pos): Return the cached position if asked
9118 about the same buffer in the same area of character positions, and
9119 the buffer wasn't changed since the time the display string
9120 position was cached.
9122 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9124 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9125 is an integer, which is important for empty lines. (Bug#9149)
9127 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9129 * frame.c (Fmodify_frame_parameters): In tty case, update the
9130 default face if necessary (Bug#4238).
9132 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9134 * editfns.c (Fstring_to_char): No need to explain what a character
9135 is in the docstring (Bug#6576).
9137 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9139 * xml.c (parse_region): Make sure we always return a tree.
9141 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9143 * xml.c (parse_region): If a document contains only comments,
9146 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9148 * xml.c (make_dom): Return comments, too.
9150 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9153 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9154 and the surrounding thread.
9155 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9156 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9157 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9159 * s/openbsd.h (BROKEN_SIGIO): Define.
9160 * unexelf.c (unexec) [__OpenBSD__]:
9161 Don't update the .mdebug section of the Alpha COFF symbol table.
9163 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9165 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9168 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9170 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9171 This fixes some race conditions on the permissions of any newly
9174 * alloc.c (valid_pointer_p): Use pipe, not open.
9175 This fixes some permissions issues when debugging.
9177 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9178 If fchown fails to set both uid and gid, try to set just gid,
9179 as that is sometimes allowed. Adjust the file's mode to eliminate
9180 setuid or setgid bits that are inappropriate if fchown fails.
9182 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9184 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9185 to compare Lisp_Objects.
9186 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to

9195 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9196 symbol character follows.
9198 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9200 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9201 This works around a problem with the previous change to Fcopy_file.
9202 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9203 and without this change, GCC might complain about discarding
9204 fchown's return value.
9206 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9208 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9210 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9212 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9214 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9216 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9217 it's used from the C level.
9219 * process.c: Use the same condition for POLL_FOR_INPUT in both
9220 keyboard.c and process.c (bug#1858).
9222 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9224 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9225 (Fgnutls_boot): Use it.
9227 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9229 * doc.c (Fsubstitute_command_keys): Revert last change.
9231 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9233 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9234 quotes the next character, and doesn't affect other longer
9235 sequences (bug#8935).
9237 * lread.c (syms_of_lread): Clarify that is isn't only
9238 `eval-buffer' and `eval-defun' that's affected by
9239 `lexical-binding' (bug#8460).
9241 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9243 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9244 bidi redisplay when a line includes both an image and is truncated.
9246 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9248 Fix minor problems found by static checking.
9249 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9250 (elsz): Now a signed constant, not a size_t var. We prefer signed
9251 types to unsigned, to avoid integer comparison confusion. Without
9252 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9253 "cannot optimize loop, the loop counter may overflow", a symptom
9255 * indent.c (Fvertical_motion): Mark locals as initialized.
9256 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9258 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9260 * search.c (Fre_search_backward): Mention `case-fold-search' in
9261 all the re_search_* functions (bug#8138).
9263 * keyboard.c (Fopen_dribble_file): Document when the file is

9279 Initialize itb.string.lstring.
9280 (init_iterator): Call bidi_init_it only of a valid
9281 buffer position was specified. Initialize paragraph_embedding to
9283 (reseat_to_string): Initialize the bidi iterator.
9284 (display_string): If we need to ignore text properties of
9285 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9286 original value of -1 will not work with bidi.)

9288 `text_pos *'; all callers changed. Support display properties on
9290 (compute_display_string_end): Support display properties on Lisp
9292 (init_iterator, reseat_1, reseat_to_string): Initialize the
9293 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9294 when iterating on a string not from display properties).
9295 (compute_display_string_pos, compute_display_string_end):
9296 Fix calculation of the object to scan. Fixes an error when using
9298 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9299 base_level_stop; instead, set base_level_stop to BEGV.
9300 Fixes crashes in vertical-motion.
9301 (next_element_from_buffer): Improve commentary for when
9302 the iterator is before prev_stop.
9303 (init_iterator): Initialize bidi_p from the default value of
9304 bidi-display-reordering, not from buffer-local value. Use the
9305 buffer-local value only if initializing for buffer iteration.
9306 (handle_invisible_prop): Support invisible properties on strings
9307 that are being bidi-reordered.
9308 (set_iterator_to_next): Support bidi reordering of C strings and

9325 (get_visually_first_element): New function, refactored from common
9326 parts of next_element_from_buffer, next_element_from_string, and
9327 next_element_from_c_string.
9328 (tool_bar_lines_needed, redisplay_tool_bar)
9329 (display_menu_bar): Force left-to-right direction. Add a FIXME
9330 comment for making that be controlled by a user option.

9344 pushed the iterator stack, restore the internal state of the bidi
9345 iterator by calling bidi_pop_it same number of times.
9346 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9347 and we are bidi-iterating, don't decrement the iterator position;
9348 instead, set the first_elt flag in the bidi iterator, to produce
9350 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9351 (push_display_prop): xassert that we are iterating a buffer.
9352 (push_it, pop_it): Save and restore paragraph_embedding member.

9361 from_disp_prop_p flag.
9362 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9385 (init_iterator): Empty the bidi cache "stack".
9386 (move_it_in_display_line_to): If iterator ended up at

9412 changed. Support iteration over a string. Support strings with
9413 display properties. Support unibyte strings. Fix the type of
9414 `len' according to what STRING_CHAR_AND_LENGTH expects.

9521 * character.c (Fcharacterp): Don't advertise optional ignored
9522 argument. (Bug#4026)

9821 Random fixes. E.g., (random) never returned negative values.
9822 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9823 subseconds part to the entropy, as that's a bit more random.
9824 Prefer signed to unsigned, since the signedness doesn't matter and
9825 in general we prefer signed. When given a limit, use a
9826 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9827 latter isn't right if USE_2_TAGS_FOR_INTS.
9828 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9829 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9842 This is more efficient than Ffile_directory_p and avoids a minor race.
9844 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9846 * buffer.c (Foverlay_put): Say what the return value is
9849 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9850 is a directory before asking whether to use the file name
9852 (barf_or_query_if_file_exists): Make the "File is a directory"
9853 error be more correct.
9855 * fns.c (Frequire): Remove the mention of the .gz files, since
9856 that's installation-specific, but keep the mention of
9857 `get-load-suffixes'.
9859 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9861 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9872 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9974 * eval.c (struct backtrace): Simplify and port the data structure.
9975 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9976 signed bit field, as this assumption is not portable and it makes
9977 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9978 "char debug_on_exit : 1" as this is not portable either; instead,
9979 use the portable "unsigned int debug_on_exit : 1". Remove unused
9980 member evalargs. Remove obsolete comments about cc bombing out.

10148 * print.c (printchar, strout): Check for string overflow.
10149 (PRINTPREPARE, printchar, strout):
10150 Don't set size unless allocation succeeds.
10152 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10153 for sizes. Check for string overflow more accurately.
10154 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.

10157 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10158 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10162 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10164 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10166 * lread.c: Integer overflow fixes.
10167 (read_integer): Radix is now EMACS_INT, not int,
10168 to improve quality of diagnostics for out-of-range radices.
10169 Calculate buffer size correctly for out-of-range radices.
10170 (read1): Check for integer overflow in radices, and in
10171 read-circle numbers.
10172 (read_escape): Avoid int overflow.
10173 (Fload, openp, read_buffer_size, read1)
10174 (substitute_object_recurse, read_vector, read_list, map_obarray):

10190 2011-06-22 Leo Liu <sdl.web@gmail.com>
10192 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10193 Move to minibuffer.el.
10195 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10197 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10198 The following patches are for when GLYPH_DEBUG && !XASSERT.
10199 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10200 * dispnew.c (flush_stdout):
10201 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10202 Mark as externally visible.
10203 * dispnew.c (check_window_matrix_pointers): Now static.
10204 * dispnew.c (window_to_frame_vpos):
10205 * xfns.c (unwind_create_frame):
10206 * xterm.c (x_check_font): Remove unused local.
10207 * scroll.c (CHECK_BOUNDS):
10208 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10209 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10210 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10211 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10212 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10214 (debug_method_add): Use va_list and vsprintf rather than relying
10215 on undefined behavior with wrong number of arguments.
10216 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10217 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10218 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10219 since we're not interested in debugging glyphs with old libraries.
10220 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10221 GCC 4.6.0's static checking.
10223 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

10241 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10242 (.bitmaps_last, struct x_output.icon_bitmap):
10243 Use ptrdiff_t, not int, for bitmap indexes.
10244 (x_allocate_bitmap_record): Check for size overflow.
10245 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10247 Use ptrdiff_t, not int, for overlay counts.
10248 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10249 * editfns.c (overlays_around, get_pos_property):
10250 * textprop.c (get_char_property_and_overlay):
10251 * xdisp.c (next_overlay_change, note_mouse_highlight):
10252 * xfaces.c (face_at_buffer_position):
10253 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10254 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10255 (Fnext_overlay_change, Fprevious_overlay_change)
10256 (mouse_face_overlay_overlaps, Foverlays_in):
10257 Use ptrdiff_t, not int, for sizes.
10258 (overlays_at, overlays_in): Check for size-calculation overflow.
10260 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10262 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10263 (x_session_initialize): Do not assume string length fits in int.
10265 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10266 This is unlikely, but can occur if DPI is outlandish.
10268 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10269 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

10272 * xrdb.c (magic_file_p, search_magic_path):
10273 Omit last arg SUFFIX; it was always 0. All callers changed.
10274 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10276 * xfont.c (xfont_match): Avoid need for strlen.
10278 * xfns.c: Don't assume strlen fits in int.

10281 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10282 not unsigned long, as we prefer signed integers. All callers changed.
10283 Detect integer overflow in repeat count.
10284 (message_dolog): Don't assume print length fits in 39 bytes.
10285 (display_mode_element): Don't assume strlen fits in int.
10287 * termcap.c: Don't assume sizes fit in int and never overflow.
10288 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10289 (gobble_line): Check for size-calculation overflow.
10291 * minibuf.c (Fread_buffer):
10292 * lread.c (intern, intern_c_string):

10306 * filelock.c: Fix some buffer overrun and integer overflow issues.
10307 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10308 Reformulate so as not to need the command string.
10309 Invoke gzip -cd rather than gunzip, as it's more portable.
10310 (lock_info_type, lock_file_1, lock_file):
10311 Don't assume pid_t and time_t fit in unsigned long.
10312 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10313 (current_lock_owner): Prefer signed type for sizes.
10314 Use memcpy, not strncpy, where memcpy is what is really wanted.
10315 Don't assume (via atoi) that time_t and pid_t fit in int.
10316 Check for time_t and/or pid_t out of range, e.g., via a network share.
10317 Don't alloca where an auto var works fine.
10319 * fileio.c: Fix some integer overflow issues.
10320 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10321 Don't assume string length fits in int.
10322 (directory_file_name): Don't assume string length fits in long.
10323 (make_temp_name): Don't assume pid fits in int, or that its print
10324 length is less than 20.

10344 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10346 * lread.c (invalid_syntax): Omit length argument.
10347 All uses changed. This doesn't fix a bug, but it simplifies the
10348 code away from its former Hollerith-constant appearance, and it's
10349 one less 'int' to worry about when looking at integer-overflow issues.
10350 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10352 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10353 This didn't break anything, but it didn't help either.
10354 It's confusing to put a bogus integer in a place where the actual
10355 value does not matter.
10356 (LIST_END_P): Remove unused macro and its bogus comment.
10357 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10359 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10360 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10362 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10363 We prefer signed types, and the value cannot exceed the EMACS_INT
10364 range anyway (because otherwise the length would not be representable).
10365 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10366 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10367 This avoids a GCC warning when WIDE_EMACS_INT.
10369 * indent.c (sane_tab_width): New function.
10370 (current_column, scan_for_column, Findent_to, position_indentation)
10371 (compute_motion): Use it. This is just for clarity.
10372 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10374 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

10378 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10380 * editfns.c, insdel.c:
10381 Omit unnecessary forward decls, to simplify future changes.
10383 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10385 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10387 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10388 Use much-faster test for byte-length change.
10389 Don't assume string byte-length fits in 'int'.
10390 Check that character arg fits in 'int'.
10391 (mapcar1): Declare byte as byte, for clarity.
10393 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10395 * fns.c (concat): Catch string overflow earlier.
10396 Do not rely on integer wraparound.
10398 * dispextern.h (struct it.overlay_strings_charpos)
10399 (struct it.selective): Now EMACS_INT, not int.
10400 * xdisp.c (forward_to_next_line_start)
10401 (back_to_previous_visible_line_start)
10402 (reseat_at_next_visible_line_start, next_element_from_buffer):
10403 Don't arbitrarily truncate the value of 'selective' to int.
10405 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10407 * composite.c: Don't truncate sizes to 'int'.
10408 (composition_gstring_p, composition_reseat_it)
10409 (composition_adjust_point): Use EMACS_INT, not int.
10410 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10411 not EMACS_UINT, for indexes.
10413 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10415 * buffer.c: Include <verify.h>.
10416 (struct sortvec.priority, struct sortstr.priority):
10417 Now EMACS_INT, not int.
10418 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10419 (struct sortstr.size, record_overlay_string)
10420 (struct sortstrlist.size, struct sortlist.used):
10421 Don't truncate size to int.
10422 (record_overlay_string): Check for size-calculation overflow.
10423 (init_buffer_once): Check at compile-time, not run-time.
10425 2011-06-22 Jim Meyering <meyering@redhat.com>
10427 Don't leak an XBM-image-sized buffer
10428 * image.c (xbm_load): Free the image buffer after using it.
10430 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10433 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10434 that Sun C diagnosed.
10435 * fns.c (secure_hash): Fix pointer signedness issue.
10436 * intervals.c (static_offset_intervals): New function.
10437 (offset_intervals): Use it.
10439 2011-06-21 Leo Liu <sdl.web@gmail.com>
10442 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10445 * fns.c (secure_hash): Rename from crypto_hash_function and change
10446 the first arg to accept symbols.
10447 (Fsecure_hash): New primitive.
10448 (syms_of_fns): New symbols.
10450 2011-06-20 Deniz Dogan <deniz@dogan.se>
10452 * process.c (Fset_process_buffer): Clarify return value in

10463 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10466 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10467 check till after the cache is created in init_frame_faces.
10469 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10471 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10473 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10475 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10476 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10477 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10479 Improve buffer-overflow checking (Bug#8873).
10480 * fileio.c (Finsert_file_contents):
10481 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10482 Remove the old (too-loose) buffer overflow checks.
10483 They weren't needed, since make_gap checks for buffer overflow.
10484 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10485 The old code merely checked for Emacs fixnum overflow, and relied
10486 on undefined (wraparound) behavior. The new code avoids undefined
10487 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10489 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10490 Tune. Don't use wider integers than needed. Don't use alloca.
10491 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10493 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10495 * insdel.c, lisp.h (buffer_overflow): New function.
10496 (insert_from_buffer_1, replace_range, replace_range_2):
10497 * insdel.c (make_gap_larger):
10498 * editfns.c (Finsert_char):
10499 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10501 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10503 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10505 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10507 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10508 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10510 * fileio.c: Don't assume EMACS_INT fits in off_t.
10511 (emacs_lseek): New static function.
10512 (Finsert_file_contents, Fwrite_region): Use it.
10513 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10515 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10517 * fns.c: Don't overflow int when computing a list length.
10518 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10519 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10520 truncation on 64-bit hosts. Check for QUIT every
10521 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10522 faster and is responsive enough.
10523 (Flength): Report an error instead of overflowing an integer.
10524 (Fsafe_length): Return a float if the value is not representable
10525 as a fixnum. This shouldn't happen except in contrived situations.
10526 (Fnthcdr, Fsort): Don't assume list length fits in int.
10527 (Fcopy_sequence): Don't assume vector length fits in int.
10529 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10530 (header_size, word_size): New constants.
10531 (allocate_vectorlike): Don't check size overflow here.
10532 (allocate_vector): Check it here instead, since this is the only
10533 caller of allocate_vectorlike that could cause overflow.
10534 Check that the new vector's length is representable as a fixnum.
10536 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10537 The previous code was bogus. For example, next_almost_prime (32)
10538 returned 39, which is undesirable as it is a multiple of 3; and
10539 next_almost_prime (24) returned 25, which is a multiple of 5 so
10540 why was the code bothering to check for multiples of 7?
10542 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10544 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10546 Variadic C functions now count arguments with ptrdiff_t.
10547 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10548 Back then I didn't know that the Emacs coding style prefers signed int.
10549 Also, in the meantime I found a few more instances where arguments
10550 were being counted with int, which may truncate counts on 64-bit
10551 machines, or EMACS_INT, which may be unnecessarily wide.
10552 * lisp.h (struct Lisp_Subr.function.aMANY)
10553 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10554 Arg counts are now ptrdiff_t, not size_t.
10555 All variadic functions and their callers changed accordingly.
10556 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10557 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10558 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10559 * callint.c (Fcall_interactively): Check arg count for overflow,
10560 to avoid potential buffer overrun. Use signed char, not 'int',
10561 for 'varies' array, so that we needn't bother to check its size
10562 calculation for overflow.
10563 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10564 * eval.c (apply_lambda):
10565 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10566 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10567 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10569 * callint.c (Fcall_interactively): Don't use index var as event count.
10571 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10572 * mem-limits.h (SIZE): Remove; no longer used.
10574 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10576 Remove unnecessary casts.
10577 * xterm.c (x_term_init):
10578 * xfns.c (x_set_border_pixel):
10579 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10580 These aren't needed now that we assume ANSI C.
10582 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10583 It's more likely to cause problems (due to unsigned overflow)
10586 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10588 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10590 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10592 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10594 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10596 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10598 GLYPH_CODE_FACE returns EMACS_INT, not int.
10599 * dispextern.h (merge_faces):
10600 * xfaces.c (merge_faces):
10601 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10602 Don't assume EMACS_INT fits in int.
10604 * character.h (CHAR_VALID_P): Remove unused parameter.
10605 * fontset.c, lisp.h, xdisp.c: All uses changed.
10607 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10609 * fns.c (concat): Minor tuning based on overflow analysis.
10610 This doesn't fix any bugs. Use int to hold character, instead
10611 of constantly refetching from Emacs object. Use XFASTINT, not
10612 XINT, for value known to be a character. Don't bother comparing
10613 a single byte to 0400, as it's always less.
10615 * floatfns.c (Fexpt):
10616 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10618 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10621 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10623 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10624 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10625 incorrectly succeed when S was a string, because 4294967386 was
10626 truncated before it was used.
10628 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10629 Otherwise, an out-of-range integer could cause undefined behavior
10632 * composite.c: Use int, not EMACS_INT, for characters.
10633 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10634 EMACS_INT, for values that are known to be in character range.
10635 This doesn't fix any bugs but is the usual style inside Emacs and
10636 may generate better code on 32-bit machines.
10638 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10639 This is for reasons similar to the recent CHAR_STRING fix.
10640 * charset.c (Fencode_char): Check that character arg is actually
10641 a character. Pass an int to ENCODE_CHAR.
10642 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10643 wider than 'int', as a compile-time check to prevent future regressions
10646 * character.c (char_string): Remove unnecessary casts.
10648 Make sure a 64-bit char is never passed to CHAR_STRING.
10649 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10650 by silently ignoring the top 32 bits, allowing some values
10651 that were far too large to be valid characters.
10652 * character.h: Include <verify.h>.
10653 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10654 arguments are no wider than unsigned, as a compile-time check
10655 to prevent future regressions in this area.
10657 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10658 (Fsubst_char_in_region):
10660 * xdisp.c (decode_mode_spec_coding):
10661 Adjust to CHAR_STRING's new requirement.
10662 * editfns.c (Finsert_char, Fsubst_char_in_region):
10663 * fns.c (concat): Check that character args are actually
10664 characters. Without this test, these functions did the wrong
10665 thing with wildly out-of-range values on 64-bit hosts.
10667 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10668 These casts should not be needed on 32-bit hosts, either.
10669 * keyboard.c (read_char):
10670 * lread.c (Fload): Remove casts to unsigned.
10672 * lisp.h (UNSIGNED_CMP): New macro.
10673 This fixes comparison bugs on 64-bit hosts.
10674 (ASCII_CHAR_P): Use it.
10675 * casefiddle.c (casify_object):
10676 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10677 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10678 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10679 * dispextern.h (FACE_FROM_ID):
10680 * keyboard.c (read_char): Use UNSIGNED_CMP.
10682 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10683 not to EMACS_INT, to avoid GCC warning.
10685 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10687 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10688 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10689 isn't needed on 32-bit machines.
10691 * buffer.c (Fgenerate_new_buffer_name):
10692 Use EMACS_INT for count, not int.
10693 (advance_to_char_boundary): Return EMACS_INT, not int.
10695 * data.c (Qcompiled_function): Now static.
10697 * window.c (window_body_lines): Now static.
10699 * image.c (gif_load): Rename local to avoid shadowing.
10701 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10702 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10703 * alloc.c (make_save_value): Integer argument is now of type
10704 ptrdiff_t, not int.
10705 (mark_object): Use ptrdiff_t, not int.
10706 * lisp.h (pD): New macro.
10707 * print.c (print_object): Use it.
10709 * alloc.c: Use EMACS_INT, not int, to count objects.
10710 (total_conses, total_markers, total_symbols, total_vector_size)
10711 (total_free_conses, total_free_markers, total_free_symbols)
10712 (total_free_floats, total_floats, total_free_intervals)
10713 (total_intervals, total_strings, total_free_strings):
10714 Now EMACS_INT, not int. All uses changed.
10715 (Fgarbage_collect): Compute overall total using a double, so that
10716 integer overflow is less likely to be a problem. Check for overflow
10717 when converting back to an integer.
10718 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10719 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10720 These were 'int' variables that could overflow on 64-bit hosts;
10721 they were never used, so remove them instead of repairing them.
10722 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10723 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10724 Previously, this ceilinged at INT_MAX, but that doesn't work on
10726 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10728 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10729 (allocate_vectorlike): Check for ptrdiff_t overflow.
10730 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10731 when a (possibly-narrower) signed value would do just as well.
10732 We prefer using signed arithmetic, to avoid comparison confusion.
10734 * alloc.c: Catch some string size overflows that we were missing.
10735 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10736 for convenience in STRING_BYTES_MAX.
10737 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10738 The definition here is exact; the one in lisp.h was approximate.
10739 (allocate_string_data): Check for string overflow. This catches
10740 some instances we weren't catching before. Also, it catches
10741 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10742 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10743 and ptrdiff_t and EMACS_INT are both 64 bits.
10745 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10746 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10747 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10749 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10751 * alloc.c (Fmake_string): Check for out-of-range init.
10753 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10755 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10757 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10759 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10760 xg_get_default_scrollbar_width.
10762 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10763 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10764 (style_changed_cb): Call update_theme_scrollbar_width and call
10765 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10766 all frames (Bug#8505).
10767 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10768 Call gtk_window_set_resizable if HAVE_GTK3.
10769 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10770 and height if HAVE_GTK3 (Bug#8505).
10771 (scroll_bar_width_for_theme): New variable.
10772 (update_theme_scrollbar_width): New function.
10773 (xg_get_default_scrollbar_width): Move code to
10774 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10775 (xg_initialize): Call update_theme_scrollbar_width.
10777 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10779 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10781 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10783 * frame.c (make_frame): Call other_buffer_safely instead of
10786 * window.c (temp_output_buffer_show): Call display_buffer with
10787 second argument Vtemp_buffer_show_specifiers and reset latter
10788 immediately after the call.
10789 (Vtemp_buffer_show_specifiers): New variable.
10790 (auto_window_vscroll_p, next_screen_context_lines)
10791 (Vscroll_preserve_screen_position): Remove leading asterisks from
10794 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10796 Fix minor problems found by GCC 4.6.0 static checking.
10797 * buffer.c (Qclone_number): Remove for now, as it's unused.
10798 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10799 (record_buffer): Remove unused local.
10800 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10801 (set_frame_buffer_list): Remove; unused.
10802 * frame.h (other_visible_frames): Remove decl.
10803 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10804 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10805 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10807 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10808 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10809 Define only if HAVE_GPM.
10810 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10811 (update_hints_inhibit): Remove; never set. All uses removed.
10812 * widgetprv.h (emacsFrameClassRec): Remove decl.
10813 * window.c (delete_deletable_window): Now returns void, since it
10814 wasn't returning anything.
10815 (compare_window_configurations): Remove unused locals.
10816 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10817 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10818 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10819 the same widths as pointers. This follows up on the 2011-05-06 patch.
10820 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10821 * xterm.h: Likewise.
10822 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10824 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
10826 * makefile.w32-in: Update dependencies.
10827 (LISP_H): Add lib/intprops.h.
10829 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10831 * image.c (gif_load): Add animation frame delay to the metadata.
10832 (syms_of_image): Use DEFSYM. New symbol `delay'.
10834 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10836 * window.c (delete_deletable_window): Re-add.
10837 (Fset_window_configuration): Rewrite to handle dead buffers and
10838 consequently deletable windows.
10839 (window_tree, Fwindow_tree): Remove. Supply functionality in
10841 (compare_window_configurations): Simplify code.
10843 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10845 * image.c (imagemagick_load_image): Fix type mismatch.
10846 (Fimagemagick_types): Likewise.
10848 * window.h (replace_buffer_in_windows): Declare.
10850 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10852 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10853 Qclone_number. Remove external declaration of Qdelete_window.
10854 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10856 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10857 Run Qbuffer_list_update_hook if allowed.
10858 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10859 buffer list implementation.
10860 (other_buffer_safely): New function.
10861 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10862 calls to replace_buffer_in_windows and
10863 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10865 (record_buffer): Inhibit quitting and rewrite using quittable
10866 functions. Run Qbuffer_list_update_hook if allowed.
10867 (Frecord_buffer, Funrecord_buffer): New functions.
10868 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10869 Move switch-to-buffer to window.el.
10870 (bury-buffer): Move to window.el.
10871 (Vbuffer_list_update_hook): New variable.
10873 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10876 * window.h (resize_frame_windows): Move up in code.
10877 (Fwindow_frame): Remove EXFUN.
10878 (replace_buffer_in_all_windows): Remove prototype.
10879 (replace_buffer_in_windows_safely): Add prototype.
10881 * window.c: Declare Qdelete_window static again. Move down
10882 declaration of select_count.
10883 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10884 (Fother_window): Move to window.el.
10885 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10886 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
10887 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
10889 (replace_buffer_in_windows): Implement by calling
10890 Qreplace_buffer_in_windows.
10891 (replace_buffer_in_all_windows): Remove with some functionality
10892 moved into replace_buffer_in_windows_safely.
10893 (replace_buffer_in_windows_safely): New function.
10894 (select_window_norecord, select_frame_norecord): Move in front

11342 (display_prop_intangible_p): Reimplement to call
11343 handle_display_spec instead of single_display_spec_intangible_p.
11344 Accept 3 additional arguments needed by handle_display_spec.
11345 This fixes incorrect cursor motion across display property with complex
11346 values: lists, `(when COND...)' forms, etc.
11347 (single_display_spec_string_p): Support property values that are
11348 lists with the argument STRING its top-level element.
11349 (display_prop_string_p): Fix the condition for processing a
11350 property that is a list to be consistent with handle_display_spec.
11351 (handle_display_spec): New function, refactored from the
11352 last portion of handle_display_prop.
11353 (compute_display_string_pos): Accept additional argument
11354 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11355 value of a `display' property is a "replacing spec".
11356 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11357 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11358 the display property, but just return a value indicating whether
11359 the display property will replace the characters it covers.
11360 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11361 frame_window_p members of struct bidi_it.
11362 (compute_display_string_pos, compute_display_string_end):
11364 (push_it): Accept second argument POSITION, where pop_it should
11365 jump to continue iteration.
11366 (reseat_1): Initialize bidi_it.disp_pos.
11368 * keyboard.c (adjust_point_for_property): Adjust the call to
11369 display_prop_intangible_p to its new signature.
11371 * dispextern.h (struct bidi_it): New member frame_window_p.
11372 (bidi_init_it): Update prototypes.
11373 (display_prop_intangible_p): Update prototype.
11374 (compute_display_string_pos, compute_display_string_end):
11375 Declare prototypes.
11376 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11379 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11381 Malloc failure behavior now depends on size of allocation.
11382 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11383 * lisp.h: Change signatures accordingly.
11384 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11385 All callers changed. (Bug#8762)
11387 * gnutls.c: Use Emacs's memory allocators.
11388 Without this change, the gnutls library would invoke malloc etc.
11389 directly, which causes problems on non-SYNC_INPUT hosts, and which
11390 runs afoul of improving memory_full behavior. (Bug#8761)
11391 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11392 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11393 xfree instead of the default malloc, realloc, free.
11394 (Fgnutls_boot): No need to check for memory allocation failure,
11395 since xmalloc does that for us.
11397 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11398 * category.c (hash_get_category_set):
11399 * ccl.c (ccl_driver):

11411 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11412 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11413 * image.c (make_image, search_image_cache, lookup_image)
11414 (xpm_put_color_table_h):
11415 * lisp.h (struct Lisp_Hash_Table):
11416 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11417 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11418 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11419 * alloc.c (allocate_vectorlike):
11420 Check for overflow in vector size calculations.
11421 * ccl.c (ccl_driver):
11422 Check for overflow when converting EMACS_INT to int.
11423 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11424 need to be updated by these changes.
11425 * fns.c (make_hash_table, maybe_resize_hash_table):
11426 Check for integer overflow with large hash tables.
11427 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11428 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11429 (SXHASH_REDUCE): New macro.
11430 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11431 Use it instead of discarding useful hash info with large hash values.
11432 (sxhash_float): New function.
11433 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11434 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11435 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11436 Rewrite to use FIXNUM_BITS, as this simplifies things.
11437 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11438 Adjust signatures to match updated version of code.
11439 (consing_since_gc): Now EMACS_INT, since a single hash table can
11440 use more than INT_MAX bytes.
11442 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11444 Make it possible to build with GCC-4.6+ -O2 -flto.
11446 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11448 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11450 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11451 Call minibuffer-inactive-mode.
11453 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11455 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11456 Update dependencies.
11458 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11460 * data.c (init_data): Remove code for UTS, this system is not
11463 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11465 Don't force ./temacs to start in terminal mode.
11467 * frame.c (make_initial_frame): Initialize faces in all cases, not
11468 only when CANNOT_DUMP is defined.
11469 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11471 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11473 * dispnew.c (add_window_display_history): Use const for the string
11474 pointer. Remove declaration, not needed.
11476 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11478 Use 'inline', not 'INLINE'.
11479 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11480 * alloc.c, fontset.c (INLINE): Remove.
11481 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11482 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11483 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11484 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11485 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11487 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11489 Make it possible to run ./temacs.
11491 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11492 syms_of_callproc does the same thing. Remove test for
11493 "initialized", do it in the caller.
11494 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11496 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11498 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11499 (read_minibuf): Use get_minibuffer.
11500 (syms_of_minibuf): Use DEFSYM.
11501 (Qmetadata): New var.
11502 * data.c (Qbuffer): Don't make it static.
11503 (syms_of_data): Use DEFSYM.
11505 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11507 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11508 (CCL_CODE_MIN): New macro.
11510 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11512 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11514 * eval.c (Qdebug): Now static.
11515 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11516 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11517 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11519 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11521 * image.c: Various fixes to ImageMagick code comments.
11522 (Fimagemagick_types): Doc fix.
11524 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11526 Minor fixes prompted by GCC 4.6.0 warnings.
11528 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11530 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11531 (x_clipboard_manager_save_all): Move extern decl to ...
11532 * xterm.h: ... here, so that it can be checked for consistency.
11534 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11536 * xselect.c (x_clipboard_manager_save_frame)
11537 (x_clipboard_manager_save_all): New functions.
11538 (Fx_clipboard_manager_save): Lisp function deleted.
11540 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11541 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11543 * xterm.h: Update prototype.
11545 2011-05-28 William Xu <william.xwl@gmail.com>
11547 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11548 exiting (Bug#8239).
11550 2011-05-28 Jim Meyering <meyering@redhat.com>
11552 Avoid a sign-extension bug in crypto_hash_function.
11553 * fns.c (to_uchar): Define.
11554 (crypto_hash_function): Use it to convert some newly-signed
11555 variables to unsigned, to avoid sign-extension bugs. For example,
11556 without this change, (md5 "truc") would evaluate to
11557 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11558 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11559 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11561 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11563 Integer overflow fixes.
11565 * dbusbind.c: Serial number integer overflow fixes.
11566 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11567 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11568 to hold a serial number that is too large for a fixnum.
11569 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11570 Check for serial numbers out of range. Decode any serial number
11571 that was so large that it became a float. (Bug#8722)
11573 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11574 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11575 Use XFASTINT rather than XUINT when numbers are nonnegative.
11576 (xd_append_arg, Fdbus_method_return_internal):
11577 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11578 arguments, check that Lisp number is nonnegative, rather than
11579 silently wrapping negative numbers around. (Bug#8722)
11580 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11583 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11585 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11587 ccl: Add integer overflow checks.
11588 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11589 (IN_INT_RANGE): New macros.
11590 (ccl_driver): Use them to check for integer overflow when
11591 decoding a CCL program. Many of the new checks are whether XINT (x)
11592 fits in int; it doesn't always, on 64-bit hosts. The new version
11593 doesn't catch all possible integer overflows, but it's an
11594 improvement. (Bug#8719)
11596 * alloc.c (make_event_array): Use XINT, not XUINT.
11597 There's no need for unsigned here.
11599 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11600 This follows up to the 2011-05-06 change that substituted uintptr_t
11601 for EMACS_INT. This case wasn't caught back then.
11603 Rework Fformat to avoid integer overflow issues.
11604 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11605 now (part of C89). Include <verify.h>.
11606 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11607 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11608 (Fformat): Avoid the prepass trying to compute sizes; it was only
11609 approximate and thus did not catch overflow reliably. Instead, walk
11610 through the format just once, formatting and computing sizes as we go,
11611 checking for integer overflow at every step, and allocating a larger
11612 buffer as needed. Keep track separately whether the format is
11613 multibyte. Keep only the most-recently calculated precision, rather
11614 than them all. Record whether each argument has been converted to
11615 string. Use EMACS_INT, not int, for byte and char and arg counts.
11616 Support field widths and precisions larger than INT_MAX. Avoid
11617 sprintf's undefined behavior with conversion specifications such as %#d
11618 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11619 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11620 formatting out-of-range floating point numbers with int
11621 formats. (Bug#8668)
11623 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11625 * data.c: Avoid integer truncation in expressions involving floats.
11626 * data.c: Include <intprops.h>.
11627 (arith_driver): When there's an integer overflow in an expression
11628 involving floating point, convert the integers to floating point
11629 so that the resulting value does not suffer from catastrophic
11630 integer truncation. For example, on a 64-bit host (* 4
11631 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11632 Do not rely on undefined behavior after integer overflow.
11634 merge count_size_as_multibyte, parse_str_to_multibyte
11635 * character.c, character.h (count_size_as_multibyte):
11636 Rename from parse_str_to_multibyte; all uses changed.
11637 Check for integer overflow.
11638 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11639 since it's now a duplicate of the other. This is more of
11640 a character than a buffer op, so better that it's in character.c.
11641 * fns.c, print.c: Adjust to above changes.
11643 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11645 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11647 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11649 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11650 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11651 (x_clipboard_manager_save): Now static.
11652 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11654 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11655 (crypto_hash_function): Now static.
11656 Fix pointer signedness problems. Avoid unnecessary initializations.
11658 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11660 * termhooks.h (Vselection_alist): Make it terminal-local.
11662 * terminal.c (create_terminal): Initialize it.
11664 * xselect.c: Support for clipboard managers.
11665 (Vselection_alist): Move to termhooks.h as terminal-local var.
11666 (LOCAL_SELECTION): New macro.
11667 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11668 (symbol_to_x_atom): Remove gratuitous arg.
11669 (x_handle_selection_request, lisp_data_to_selection_data)
11670 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11671 (x_own_selection, x_get_local_selection, x_convert_selection):
11672 New arg, specifying work frame. Use terminal-local Vselection_alist.
11673 (some_frame_on_display): Delete unused function.
11674 (Fx_own_selection_internal, Fx_get_selection_internal)
11675 (Fx_disown_selection_internal, Fx_selection_owner_p)
11676 (Fx_selection_exists_p): New optional frame arg.
11677 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11678 (x_handle_selection_clear): Don't treat other terminals with the
11679 same keyboard specially. Use the terminal-local Vselection_alist.
11680 (x_clear_frame_selections): Use Frun_hook_with_args.
11682 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11684 * xterm.h: Add support for those atoms.
11686 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11688 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11689 (converted_selections, conversion_fail_tag): New global variables.
11690 (x_selection_request_lisp_error): Free the above.
11691 (x_get_local_selection): Remove unnecessary code.
11692 (x_reply_selection_request): Args changed; handle arbitrary array
11693 of converted selections stored in converted_selections.
11694 Separate the XChangeProperty and SelectionNotify steps.
11695 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11696 (x_convert_selection): New function.
11697 (x_handle_selection_event): Simplify.
11698 (x_get_foreign_selection): Don't ignore incoming requests while
11699 waiting for an answer; this will fail when we implement
11700 SAVE_TARGETS, and seems unnecessary anyway.
11701 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11702 (Vx_sent_selection_functions): Doc fix.
11704 2011-05-26 Leo Liu <sdl.web@gmail.com>
11706 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11708 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11710 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11712 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11713 for fringe update if it has periodic bitmap.
11714 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11715 and fringe_bitmap_periodic_p.
11717 * fringe.c (get_fringe_bitmap_data): New function.
11718 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11719 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11720 row. Mark glyph row for fringe update if periodicity changed.
11722 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11723 for fringe update unless it has periodic bitmap.
11725 2011-05-25 Kenichi Handa <handa@m17n.org>

11742 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11743 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11744 Remove macros that are defined and never used.
11745 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11747 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11749 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11750 (Fx_get_selection_internal): Minor cleanup.
11751 (Fx_own_selection_internal): Rename arguments for consistency with
11754 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

11770 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11771 and add some more files.
11773 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11775 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11776 report_file_error introduced by the change from 2011-05-07.
11778 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11780 * systime.h (Time): Define only if emacs is defined.
11781 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11782 where the include path doesn't have X11/X.h by default. See
11783 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11785 2011-05-20 Kenichi Handa <handa@m17n.org>
11787 * composite.c (find_automatic_composition): Fix previous change.
11789 2011-05-20 Glenn Morris <rgm@gnu.org>
11791 * lisp.mk: New file, split from Makefile.in.
11792 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11793 (shortlisp): Remove.
11794 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11796 2011-05-19 Glenn Morris <rgm@gnu.org>
11798 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11799 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11800 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11801 (lisp): Set the order to that of loadup.el.
11802 (shortlisp): Make it a copy of $lisp.
11803 (SOME_MACHINE_LISP): Remove.
11804 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11805 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11807 2011-05-18 Kenichi Handa <handa@m17n.org>
11809 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11810 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11811 (find_automatic_composition): Mostly rewrite for efficiency.
11813 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11815 * makefile.w32-in: Update dependencies.
11817 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11819 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11820 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11822 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11824 Fix some integer overflow issues, such as string length overflow.
11826 * insdel.c (count_size_as_multibyte): Check for string overflow.
11828 * character.c (lisp_string_width): Check for string overflow.
11829 Use EMACS_INT, not int, for string indexes and lengths; in
11830 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11831 the resulting string length overflows an EMACS_INT; instead,
11832 report a string overflow if no precision given. When checking for
11833 precision exhaustion, use a check that cannot possibly have
11834 integer overflow. (Bug#8675)
11835 * character.h (lisp_string_width): Adjust to new signature.
11837 * alloc.c (string_overflow): New function.
11838 (Fmake_string): Use it. This doesn't change behavior, but saves
11839 a few bytes and will simplify future changes.
11840 * character.c (string_escape_byte8): Likewise.
11841 * lisp.h (string_overflow): New decl.
11843 Fixups, following up to the user-interface timestamp change.
11844 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11845 for UI timestamps, instead of unsigned long.
11846 * msdos.c (mouse_get_pos): Likewise.
11847 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11848 * w32gui.h (Time): Define by including "systime.h" rather than by
11849 declaring it ourselves. (Bug#8664)
11851 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11852 * image.c (clear_image_cache): Likewise.
11854 * term.c (term_mouse_position): Don't assume time_t wraparound.
11856 Be more systematic about user-interface timestamps.
11857 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11858 and sometimes 'EMACS_UINT', to represent these timestamps.
11859 This change causes it to use 'Time' uniformly, as that's what X uses.
11860 This makes the code easier to follow, and makes it easier to catch
11861 integer overflow bugs such as Bug#8664.
11862 * frame.c (Fmouse_position, Fmouse_pixel_position):
11863 Use Time, not unsigned long, for user-interface timestamps.
11864 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11865 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11866 * keyboard.h (last_event_timestamp): Likewise.
11867 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11868 * menu.h (xmenu_show): Likewise.
11869 * term.c (term_mouse_position): Likewise.
11870 * termhooks.h (struct input_event.timestamp): Likewise.
11871 (struct terminal.mouse_position_hook): Likewise.
11872 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11873 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11874 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11875 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11876 what it was before.
11877 * menu.h, termhooks.h: Include "systime.h", for Time.
11879 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11880 Don't assume that the difference between two unsigned long values
11881 can fit into an integer. At this point, we know button_down_time
11882 <= event->timestamp, so the difference must be nonnegative, so
11883 there's no need to cast the result if double-click-time is
11884 nonnegative, as it should be; check that it's nonnegative, just in
11885 case. This bug is triggered when events are more than 2**31 ms
11886 apart (about 25 days). (Bug#8664)
11888 * xselect.c (last_event_timestamp): Remove duplicate decl.
11889 (x_own_selection): Remove needless cast to unsigned long.
11891 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11892 that always fit in int. Use a sentinel instead of a counter, to
11893 avoid a temp and to allay GCC's concerns about possible int overflow.
11894 * frame.h (struct frame): Use int for menu_bar_items_used
11895 instead of EMACS_INT, since it always fits in int.
11897 * menu.c (grow_menu_items): Check for int overflow.
11899 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11901 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11902 Before, the code was not consistent. These values cannot exceed
11903 2**31 - 1 so there's no need to make them unsigned.
11904 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11905 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11906 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11908 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11910 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11911 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11912 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11913 presumably because the widths might not match.
11915 * window.c (size_window): Avoid needless test at loop start.
11917 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11919 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11921 2011-05-12 Drew Adams <drew.adams@oracle.com>
11923 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11925 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11927 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11928 `width' to `bar_area_x' and `bar_area_width', respectively.
11929 (x_scroll_run): Take account of fringe background extension.
11931 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11932 Rename local vars `left' and `width' to `bar_area_x' and
11933 `bar_area_width', respectively.
11934 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11935 background extension.
11937 2011-05-10 Jim Meyering <meyering@redhat.com>
11939 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11941 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11943 * image.c (Finit_image_library): Return t for built-in image types,
11944 like pbm and xbm. (Bug#8640)
11946 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11948 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11950 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11952 * w32console.c (Fset_screen_color): Doc fix.
11953 (Fget_screen_color): New function.
11954 (syms_of_ntterm): Defsubr it.
11956 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11957 unlink the temporary file if Fcall_process didn't create it in the
11959 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11960 child process will be redirected to a file specified with `:file'.
11961 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11962 cue to call_process_cleanup not to close that handle.
11964 2011-05-07 Ben Key <bkey76@gmail.com>
11966 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11967 one of two shell specific rules, either bootstrap-temacs-CMD or
11968 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11969 to the previous implementation of the bootstrap-temacs rule.
11970 The bootstrap-temacs-CMD rule is similar to the previous
11971 implementation of the bootstrap-temacs rule except that it
11972 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11975 These changes, along with some changes to nt/configure.bat,
11976 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11977 earlier fix to add support for --cflags and --ldflags options
11978 that include quotes so that it works whether make uses cmd or
11981 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11983 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11984 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11986 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11987 a string. Handle both cases.
11988 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11989 (Fdbus_register_method): Use Qinvalid_function.
11991 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11993 * makefile.w32-in: Update dependencies.
11994 (LISP_H): Add inttypes.h and stdin.h.
11995 (PROCESS_H): Add unistd.h.
11997 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11999 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12000 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12002 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12004 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12006 * term.c (vfatal): Remove stray call to va_end.
12007 It's not needed and the C Standard doesn't allow it here anyway.
12009 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12010 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12012 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12015 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12017 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12019 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12021 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12023 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12025 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12026 * charset.c (Fdefine_charset_internal): Don't initialize
12027 charset.code_space[15]. The value was garbage, on hosts with
12028 32-bit int (Bug#8600).
12030 * lread.c (read_integer): Be more consistent with string-to-number.
12031 Use string_to_number to do the actual conversion; this avoids
12032 rounding errors and fixes some other screwups. Without this fix,
12033 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12034 (digit_to_number): Move earlier, for benefit of read_integer.
12035 Return -1 if the digit is out of range for the base, -2 if it is
12036 not a digit in any supported base. (Bug#8602)
12038 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12040 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12041 to match comment at start of function. This also removes a
12042 GCC warning about overflow in a 32+64-bit port.
12044 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12046 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12047 Reported by Stefan Monnier in
12048 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12049 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12050 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12052 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12053 (EMACS_UINTPTR): Likewise, with uintptr_t.
12055 * lisp.h: Prefer 64-bit EMACS_INT if available.
12056 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12057 on 32-bit hosts that have 64-bit int, so that they can access
12059 However, temporarily disable this change unless the temporary
12060 symbol WIDE_EMACS_INT is defined.
12062 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12064 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12065 This removes an assumption that EMACS_INT and long are the same
12066 width as pointers. The assumption is true for Emacs porting targets
12067 now, but we want to make other targets possible.
12068 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12069 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12070 In the rest of the code, change types of integers that hold casted
12071 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12072 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12073 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12074 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12075 No need to cast type when ORing.
12076 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12077 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12078 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12079 assume EMACS_INT is the same width as char *.
12080 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12081 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12082 Remove no-longer-needed casts.
12083 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12084 (xg_tool_bar_help_callback, xg_make_tool_item):
12085 Use EMACS_INTPTR to hold an integer
12086 that will be cast to void *; this can avoid a GCC warning
12087 if EMACS_INT is not the same width as void *.
12088 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12089 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12090 (current_message_1, set_message_1):
12091 Use a local to convert to proper width without a cast.
12092 * xmenu.c (dialog_selection_callback): Likewise.
12094 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12095 Also, don't assume VALBITS / RAND_BITS is less than 5,
12096 and don't rely on undefined behavior when shifting a 1 left into
12098 * lisp.h (get_random): Change signature to match.
12100 * lread.c (hash_string): Use size_t, not int, for hash computation.
12101 Normally we prefer signed values; but hashing is special, because
12102 it's better to use unsigned division on hash table sizes so that
12103 the remainder is nonnegative. Also, size_t is the natural width
12104 for hashing into memory. The previous code used 'int', which doesn't
12105 retain enough info to hash well into very large tables.
12106 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12108 * dbusbind.c: Don't possibly lose pointer info when converting.
12109 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12110 Use XPNTR rather than XHASH, so that the high-order bits of
12111 the pointer aren't lost when converting through void *.
12113 * eval.c (Fautoload): Don't double-shift a pointer.
12115 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12117 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12119 * gnutls.c (DEF_GNUTLS_FN):
12120 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12122 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12124 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12127 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12129 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12130 New version that can reserve upto 2GB of heap space.
12132 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12134 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12136 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12138 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12139 `gnutls_certificate_set_x509_key_file'.
12141 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12143 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12144 Update dependencies.
12146 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12148 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12149 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12150 Remove unused parameter `fildes'.
12151 * process.c (read_process_output, send_process): Don't pass it.
12153 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12155 Fix previous change: the library cache is defined in w32.c.
12156 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12157 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12159 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12161 Implement dynamic loading of GnuTLS on Windows.
12163 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12164 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12165 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12168 * gnutls.c (Qgnutls_dll): Define.
12169 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12170 (gnutls_*): Declare function pointers.
12171 (init_gnutls_functions): New function to initialize function pointers.
12172 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12173 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12174 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12175 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12176 (emacs_gnutls_write, emacs_gnutls_read)
12177 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12178 (Fgnutls_available_p): New function.
12179 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12180 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12181 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12183 * image.c: Include w32.h.
12184 (Vimage_type_cache): Delete.
12185 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12186 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12187 (w32_delayed_load): Move to w32.c.
12189 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12191 * w32.c (QCloaded_from, Vlibrary_cache): Define.

12193 its filename in the :loaded-from property of the library id.

12195 Initialize and staticpro them.
12196 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12198 * process.c: Include lisp.h before w32.h, not after.
12199 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12200 instead of gnutls_record_check_pending.
12202 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12204 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12206 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12207 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12210 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12212 * xterm.c (x_set_frame_alpha): Do not set property on anything

12252 rather than `XVECTOR (FOO)->size'.
12254 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12255 inttypes.h, as a gnulib replacement is used if it not available in

12270 charbuf for the composition carryover bytes.
12272 2011-04-21 Eli Zaretskii <eliz@gnu.org>

12277 %llo or %llx format is passed. (Bug#8545)
12279 * window.c (window_scroll_line_based): Use a marker instead of
12280 simple variables to record original value of point. (Bug#7952)
12282 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12283 produced by %s or %c overflows available buffer space. (Bug#8545)
12285 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12287 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12288 (SIZE_MAX): Move defn after all includes, as they might #define it.
12290 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12292 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12294 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12296 * keyboard.c (Qdelayed_warnings_hook): Define.
12297 (command_loop_1): Run `delayed-warnings-hook'
12298 if Vdelayed_warnings_list is non-nil.
12299 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12300 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12302 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12304 * doprnt.c (doprnt): Don't return value smaller than the buffer
12305 size if the message was truncated. (Bug#8545).
12307 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12309 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

12312 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12314 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12316 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12318 * makefile.w32-in: Update dependencies.
12320 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12322 Improve `doprnt' and its usage. (Bug#8545)
12323 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12324 `format_end'. Remove support for %l as a conversion specifier.
12325 Don't use xrealloc. Improve diagnostics when the %l size modifier
12326 is used. Update the commentary.
12328 * eval.c (verror): Simplify calculation of size_t.
12330 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12333 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12335 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12338 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12340 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12341 This makes this file independent of the recent pseudovector change.
12343 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12345 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12347 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12348 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12349 Remove unused local.
12350 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12352 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12353 GCC 4.6.0 optimizes based on type-based alias analysis.
12354 For example, if b is of type struct buffer * and v of type struct
12355 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12356 != &v->size, and therefore "v->size = 1; b->size = 2; return
12357 v->size;" must therefore return 1. This assumption is incorrect
12358 for Emacs, since it type-puns struct Lisp_Vector * with many other
12359 types. To fix this problem, this patch adds a new type struct
12360 vectorlike_header that documents the constraints on layout of vectors
12361 and pseudovectors, and helps optimizing compilers not get fooled
12362 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12363 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12364 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12366 (XSETPVECTYPE): Rewrite in terms of new macro.
12367 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12368 This is a bit clearer, and further avoids the possibility of
12369 undesirable aliasing.
12370 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12371 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12372 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12373 since Lisp_Subr is a special case (no "next" field).
12374 (ASIZE): Now uses header.size rather than size.
12375 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12376 to avoid the hassle of writing XVECTOR (foo)->header.size.
12377 (struct vectorlike_header): New type.
12378 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12379 object, to help avoid aliasing.
12380 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12381 (SUBRP): Likewise, since Lisp_Subr is a special case.
12382 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12383 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12384 (struct Lisp_Hash_Table): Combine first two members into a single
12385 struct vectorlike_header member. All uses of "size" and "next" members
12386 changed to be "header.size" and "header.next".
12387 * buffer.h (struct buffer): Likewise.
12388 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12389 * frame.h (struct frame): Likewise.
12390 * process.h (struct Lisp_Process): Likewise.
12391 * termhooks.h (struct terminal): Likewise.
12392 * window.c (struct save_window_data, struct saved_window): Likewise.
12393 * window.h (struct window): Likewise.
12394 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12395 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12396 * buffer.c (init_buffer_once): Likewise.
12397 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12399 * process.c (Fformat_network_address): Use local var for size,
12402 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12404 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12405 * data.c (atof): Remove decl; no longer used or needed.
12406 (digit_to_number): Move to lread.c.
12407 (Fstring_to_number): Use new string_to_number function, to be
12408 consistent with how the Lisp reader treats infinities and NaNs.
12409 Do not assume that floating-point numbers represent EMACS_INT
12410 without losing information; this is not true on most 64-bit hosts.
12411 Avoid double-rounding errors, by insisting on integers when
12412 parsing non-base-10 numbers, as the documentation specifies.
12413 * lisp.h (string_to_number): New decl, replacing ...
12414 (isfloat_string): Remove.
12415 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12416 (read1): Do not accept +. and -. as integers; this
12417 appears to have been a coding error. Similarly, do not accept
12418 strings like +-1e0 as floating point numbers. Do not report
12419 overflow for integer overflows unless the base is not 10 which
12420 means we have no simple and reliable way to continue.
12421 Break out the floating-point parsing into a new
12422 function string_to_number, so that Fstring_to_number parses
12423 floating point numbers consistently with the Lisp reader.
12424 (digit_to_number): Move here from data.c. Make it static inline.
12425 (E_CHAR, EXP_INT): Remove, replacing with ...
12426 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12427 (string_to_number): New function, replacing isfloat_string.
12428 This function checks for valid syntax and produces the resulting
12429 Lisp float number too. Rework it so that string-to-number
12430 no longer mishandles examples like "1.0e+". Use strtoumax,
12431 so that overflow for non-base-10 numbers is reported only when
12432 there's no portable and simple way to convert to floating point.
12434 * textprop.c (set_text_properties_1): Rewrite for clarity,
12435 and to avoid GCC warning about integer overflow.
12437 * intervals.h (struct interval): Use EMACS_INT for members
12438 where EMACS_UINT might cause problems. See
12439 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12440 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12441 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12443 (offset_intervals): Tell GCC not to worry about length overflow
12444 when negating a negative length.
12446 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12447 (overrun_check_free): Likewise.
12449 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12450 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12453 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12454 (gnutls_make_error): Rename local to avoid shadowing.
12455 (gnutls_emacs_global_deinit): ifdef out; not used.
12456 (Fgnutls_boot): Use const for pointer to readonly storage.
12457 Comment out unused local. Fix pointer signedness problems.
12459 * lread.c (openp): Don't stuff size_t into an 'int'.
12460 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12461 about possible signed overflow.
12463 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12464 (GDK_KEY_g): Don't define if already defined.
12465 (xg_prepare_tooltip): Avoid pointer signedness problem.
12466 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12468 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12469 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12471 * xfns.c (Fx_window_property): Simplify a bit,
12472 to make a bit faster and to avoid GCC 4.6.0 warning.
12473 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12475 * fns.c (internal_equal): Don't assume size_t fits in int.
12477 * alloc.c (compact_small_strings): Tighten assertion a little.
12479 Replace pEd with more-general pI, and fix some printf arg casts.
12480 * lisp.h (pI): New macro, generalizing old pEd macro to other
12481 conversion specifiers. For example, use "...%"pI"d..." rather
12482 than "...%"pEd"...".
12483 (pEd): Remove. All uses replaced with similar uses of pI.
12484 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12485 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12486 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12487 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12488 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12489 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12490 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12492 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12493 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12494 * print.c (safe_debug_print, print_object): Likewise.
12495 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12497 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12498 avoiding the 0 flag, which is not portable.
12499 * process.c (Fmake_network_process): Use pI to avoid cast.
12500 * region-cache.c (pp_cache): Likewise.
12501 * xdisp.c (decode_mode_spec): Likewise.
12502 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12503 behavior on 64-bit hosts with printf arg.
12504 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12505 (x_stop_queuing_selection_requests): Likewise.
12506 (x_get_window_property): Don't truncate byte count to an 'int'
12509 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12510 here, since it parses constructs like leading '-' and spaces,
12511 which are not wanted; and it overflows with large numbers.
12512 Instead, simply match F[0-9]+, which is what is wanted anyway.
12514 * alloc.c: Remove unportable assumptions about struct layout.
12515 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12516 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12517 (allocate_vectorlike, make_pure_vector): Use the new macros,
12518 plus offsetof, to remove unportable assumptions about struct layout.
12519 These assumptions hold on all porting targets that I know of, but
12520 they are not guaranteed, they're easy to remove, and removing them
12521 makes further changes easier.
12523 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12524 This doesn't fix a bug but makes the code clearer.
12525 (string_overrun_cookie): Now const. Use initializers that
12526 don't formally overflow signed char, to avoid warnings.
12527 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12528 can cause Emacs to crash when string overrun checking is enabled.
12529 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12530 multiple of sizeof (EMACS_INT); it need not be, if
12531 alignof(EMACS_INT) < sizeof (EMACS_INT).
12532 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12534 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12549 (handle_user_signal): Break into debugger when debug-on-event
12550 matches the current signal symbol.
12552 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12554 * alloc.c (check_sblock, check_string_bytes)
12555 (check_string_free_list): Convert to standard C.
12557 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12559 * w32.c (emacs_gnutls_push): Fix typo.
12561 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12563 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12564 "cast to pointer from integer of different size".
12566 Improve doprnt and its use in verror. (Bug#8545)
12567 * doprnt.c (doprnt): Document the set of format control sequences
12568 supported by the function. Use SAFE_ALLOCA instead of always
12571 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12572 is one byte too soon. Don't use xrealloc; instead xfree and
12575 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12577 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12580 * gnutls.c: Renamed global_initialized to
12581 gnutls_global_initialized. Added internals for the
12582 :verify-hostname-error, :verify-error, and :verify-flags
12583 parameters of `gnutls-boot' and documented those parameters in the
12584 docstring. Start callback support.
12585 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12586 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12587 on error. Return error code.
12588 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12589 (emacs_gnutls_read): Likewise.
12590 (Fgnutls_boot): Return handshake error code.
12591 (emacs_gnutls_handle_error): New function.
12592 (wsaerror_to_errno): Likewise.
12594 * w32.h (emacs_gnutls_pull): Add prototype.
12595 (emacs_gnutls_push): Likewise.
12597 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12598 (emacs_gnutls_push): Likewise.
12600 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
12602 * process.c (wait_reading_process_output): Check if GnuTLS
12603 buffered some data internally if no FDs are set for TLS
12606 * makefile.w32-in (OBJ2): Add gnutls.$(O).
12607 (LIBS): Link to USER_LIBS.

12612 * xdisp.c (handle_single_display_spec): Rename the
12613 display_replaced_before_p argument into display_replaced_p, to
12614 make it consistent with the commentary. Fix typos in the
12617 * textprop.c (syms_of_textprop): Remove dead code.

12892 ns_descriptor_to_entity that were caused by using free to
12893 deallocate memory blocks that were allocated by xmalloc (via

12914 (emacs_read, emacs_write): Use it.
12915 * process.c (send_process): Adjust to the new signatures of
12916 emacs_write and emacs_gnutls_write. Do not attempt to store

13109 * font.c (font_close_object): Now static.
13110 * font.h (font_close_object): Remove.
13111 * fontset.c (FONTSET_OBJLIST): Remove.
13112 (free_realized_fontset) #if-0 the body, which does nothing.
13113 (face_suitable_for_char_p): #if-0, as it's never called.
13114 * fontset.h (face_suitable_for_char_p): Remove decl.
13115 * xfaces.c (face_at_string_position):
13116 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
13117 since 0 is always ASCII.
13119 * fns.c (weak_hash_tables): Now static.
13121 * fileio.c: Make symbols static if they're not exported.
13122 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

13140 * editfns.c, lisp.h (get_operating_system_release): Remove.
13141 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
13142 worth the hassle of breaking this out.
13144 * xterm.c: Make symbols static if they're not exported.
13145 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
13146 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

13248 * buffer.c (buffer_count): Remove unused var.

13257 * atimer.h (run_all_atimers): Remove; not exported.
13259 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13260 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13261 was inaccessible from Lisp.
13262 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13263 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13265 alloc.c: Import and export fewer symbols, and remove unused items.
13266 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13268 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13269 it's not optimized away by whole-program optimization.
13270 (message_enable_multibyte, free_misc): Remove.
13271 (catchlist, handlerlist, mark_backtrace):
13272 Declare only if BYTE_MARK_STACK.

13281 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13282 (mark_backtrace): Define only if BYTE_MARK_STACK.
13283 * xdisp.c (message_enable_multibyte): Now static.
13285 Declare Lisp_Object Q* variables to be 'static' if not exported.
13286 This makes it easier for human readers (and static analyzers)
13287 to see whether these variables are used from other modules.
13288 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13289 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13290 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

13298 Remove decls of unexported vars.
13299 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13301 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13303 Make Emacs functions such as Fatom 'static' by default.
13304 This makes it easier for human readers (and static analyzers)
13305 to see whether these functions can be called from other modules.
13306 DEFUN now defines a static function. To make the function external
13307 so that it can be used in other C modules, use the new macro DEFUE.
13308 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13309 (Finit_image_library):
13310 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13311 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13312 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13313 Remove decls, since these functions are now static.
13314 (Funintern, Fget_internal_run_time): New decls, since these functions
13315 were already external.
13317 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13318 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13324 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13325 Mark functions with DEFUE instead of DEFUN,
13326 if they are used in other modules.
13327 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13328 decls for now-static functions.
13329 * buffer.h (Fdelete_overlay): Remove decl.
13330 * callproc.c (Fgetenv_internal): Mark as internal.
13331 * composite.c (Fremove_list_of_text_properties): Remove decl.

13337 (Funintern): Remove extern decl; now in .h file where it belongs.
13338 * fileio.c (Fmake_symbolic_link): New forward static decl.
13339 * image.c (Finit_image_library): New forward static decl.
13340 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13341 * intervals.h (Fprevious_property_change):
13342 (Fremove_list_of_text_properties): Remove decls.
13343 * keyboard.c (Fthis_command_keys): Remove decl.
13344 (Fcommand_execute): New forward static decl.
13345 * keymap.c (Flookup_key): New forward static decl.
13346 (Fcopy_keymap): Now static.
13347 * keymap.h (Flookup_key): Remove decl.
13348 * process.c (Fget_process): New forward static decl.
13349 (Fprocess_datagram_address): Mark as internal.

13360 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13362 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13365 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13367 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13368 when at ZV. (Bug#8487)
13370 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13372 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13374 * keyboard.c (parse_tool_bar_item): Likewise.
13375 * sound.c (sound_cleanup, alsa_close): Likewise.
13376 * termcap.c (tgetent): Likewise.
13377 * xfns.c (x_default_font_parameter): Likewise.
13378 * xsettings.c (read_and_apply_settings): Likewise.
13380 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13381 (overrun_check_free): Protoize.
13383 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13385 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13386 since callers should never pass a negative size.
13387 Change the signature to match that of plain 'read' and 'write'; see
13388 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13389 * lisp.h: Update prototypes of emacs_write and emacs_read.
13391 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13393 * xdisp.c (redisplay_window): Don't try to determine the character
13394 position of the scroll margin if the window start point w->startp
13395 is outside the buffer's accessible region. (Bug#8468)
13397 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13399 Fix write-region and its subroutines for buffers > 2GB.
13400 * fileio.c (a_write, e_write): Modify declaration of arguments and
13401 local variables to support buffers larger than 2GB.
13402 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13404 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13405 argument, local variables, and return value.
13407 * lisp.h: Update prototypes of emacs_write and emacs_read.
13409 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13411 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13413 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13415 Fix more problems found by GCC 4.6.0's static checks.
13417 * xdisp.c (vmessage): Use a better test for character truncation.
13419 * charset.c (load_charset_map): <, not <=, for optimization,
13420 and to avoid potential problems with integer overflow.
13421 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13422 * casetab.c (set_identity, shuffle): Likewise.
13423 * editfns.c (Fformat): Likewise.
13424 * syntax.c (skip_chars): Likewise.
13426 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13427 This also lets GCC 4.6.0 generate slightly better loop code.
13429 * callint.c (Fcall_interactively): <, not <=, for optimization.
13430 (Fcall_interactively): Count the number of arguments produced,
13431 not the number of arguments given. This is simpler and lets GCC
13432 4.6.0 generate slightly better code.
13434 * ftfont.c: Distingish more carefully between FcChar8 and char.
13435 The previous code passed unsigned char * to a functions like
13436 strlen and xstrcasecmp that expect char *, which does not
13437 conform to the C standard.
13438 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13439 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13440 char * when the C standard requires it.
13442 * keyboard.c (read_char): Remove unused var.
13444 * eval.c: Port to Windows vsnprintf (Bug#8435).
13445 Include <limits.h>.
13446 (SIZE_MAX): Define if the headers do not.
13447 (verror): Do not give up if vsnprintf returns a negative count.
13448 Instead, grow the buffer. This ports to Windows vsnprintf, which
13449 does not conform to C99. Problem reported by Eli Zaretskii.
13450 Also, simplify the allocation scheme, by avoiding the need for
13451 calling realloc, and removing the ALLOCATED variable.
13453 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13455 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13456 But keep the doprint source code for now, as we might revamp it
13457 and use it again (Bug#8435).
13458 * lisp.h (doprnt): Remove.
13459 * Makefile.in (base_obj): Remove doprnt.o.
13460 * deps.mk (doprnt.o): Remove.
13462 error: Print 32- and 64-bit integers portably (Bug#8435).
13463 Without this change, on typical 64-bit hosts error ("...%d...", N)
13464 was used to print both 32- and 64-bit integers N, which relied on
13465 undefined behavior.
13466 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13467 * lisp.h (error, verror): Mark as printf-like functions.
13468 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13469 Report overflow in size calculations when allocating printf buffer.
13470 Do not truncate output string at its first null byte.
13471 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13472 Truncate the output at a character boundary, since vsnprintf does not
13474 * charset.c (check_iso_charset_parameter): Convert internal
13475 character to string before calling 'error', since %c now has the
13477 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13478 overflow when computing char to be passed to 'error'. Do not
13479 pass Lisp_Object to 'error'; pass the integer instead.
13480 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13481 formatted with plain %d.
13483 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13485 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13487 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13489 * xterm.c (x_catch_errors): Remove duplicate declaration.
13491 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13493 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13495 2011-04-10 Jim Meyering <meyering@redhat.com>
13497 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13498 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13499 return ssize_t not "int", and use size_t as the buffer length.
13500 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13501 * gnutls.h: Update declarations.
13502 * process.c (read_process_output): Use ssize_t, to match.
13503 (send_process): Likewise.

13512 Use unsigned char, to match FcChar8 type definition.
13514 * xterm.c (handle_one_xevent):
13515 * xmenu.c (create_and_show_popup_menu):
13516 * xselect.c (x_decline_selection_request)

13519 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13521 Fix some uses of `int' instead of EMACS_INT.
13522 * search.c (string_match_1, fast_string_match)
13523 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13524 (scan_buffer, find_next_newline_no_quit)
13525 (find_before_next_newline, search_command, Freplace_match)

13615 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13617 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13618 This avoids several warnings with gcc -Wstrict-overflow.
13619 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13620 directly, rather than having caller test rule sign. This avoids
13621 some unnecessary tests.
13622 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13623 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13624 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13626 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13627 (xfont_open): Avoid unnecessary tests.
13629 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13631 * composite.h, composite.c (composition_gstring_put_cache):
13632 Use EMACS_INT, not int, for length.
13634 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13635 breaking out part of COMPOSITION_DECODE_RULE.
13636 (COMPOSITION_DECODE_RULE): Use it.
13637 * composite.c (get_composition_id): Remove unused local vars,
13638 by using the new macro.
13640 * textprop.c (set_text_properties_1): Change while to do-while,
13641 since the condition is always true at first.
13643 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13644 (interval_deletion_adjustment): Return unsigned value.
13647 * process.c (list_processes_1, create_pty, read_process_output):
13648 (exec_sentinel): Remove vars that were set but not used.
13649 (create_pty): Remove unnecessary "volatile"s.
13650 (Fnetwork_interface_info): Avoid possibility of int overflow.

13663 * print.c (print_error_message): Avoid int overflow.
13665 * font.c (font_list_entities): Redo for clarity,
13666 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13668 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13669 (font_score): Avoid potential overflow in diff calculation.

13672 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13674 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13676 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13677 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13678 can always succeed if overflow has undefined behavior.
13680 * search.c (boyer_moore, wordify): Remove vars set but not used.
13681 (wordify): Omit three unnecessary tests.
13683 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

13686 * casefiddle.c (casify_region): Remove var that is set but not used.
13688 * dired.c (file_name_completion): Remove var that is set but not used.
13690 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13692 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13693 (Finsert_file_contents): Remove unnecessary code checking fd.
13695 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13696 Check for integer overflow on size calculations.
13698 * buffer.c (Fprevious_overlay_change): Remove var that is set
13701 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13702 Remove vars that are set but not used.
13703 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13704 (timer_check_2): Mark vars as initialized.
13706 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13708 * image.c (lookup_image): Remove var that is set but not used.
13709 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13711 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13712 that are set but not used.
13714 * xfns.c (make_invisible_cursor): Don't return garbage
13715 if XCreateBitmapFromData fails (Bug#8410).
13717 * xselect.c (x_get_local_selection, x_handle_property_notify):
13718 Remove vars that are set but not used.
13720 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13721 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13723 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13724 Remove var that is set but not used.
13725 (scroll_bar_windows_size): Now size_t, not int.
13726 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13727 Check for overflow.
13729 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13730 (map_tty_color) [!defined MSDOS]: Likewise.
13732 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13734 * coding.c: Remove vars that are set but not used.
13735 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13736 All callers changed.
13737 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13738 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13739 (decode_coding_charset): Remove vars that are set but not used.
13741 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13742 that is set but not used.
13744 * print.c (print_object): Remove var that is set but not used.
13746 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13747 The gnulib version avoids calling malloc in the usual case,
13748 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13749 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13750 * filelock.c (current_lock_owner): Likewise.
13751 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13752 * sysdep.c: Include allocator.h, careadlinkat.h.
13753 (emacs_no_realloc_allocator): New static constant.
13754 (emacs_readlink): New function.
13755 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13756 ../lib/careadlinkat.h.
13758 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13760 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13761 first non-nil return value).

13765 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13766 if not defined (Bug#8403).
13768 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13770 * xdisp.c (display_count_lines): Remove parameter `start',
13771 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13772 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13773 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13775 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13776 and thereabouts. All callers changed.
13777 (get_per_char_metric): Remove parameter `f', unused since
13778 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13780 2011-04-02 Jim Meyering <meyering@redhat.com>
13782 do not dereference NULL upon failed strdup
13783 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13784 (ns_get_family): Likewise.
13786 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13788 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13790 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13792 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13795 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13797 Add lexical binding.
13799 * window.c (Ftemp_output_buffer_show): New fun.
13800 (Fsave_window_excursion):
13801 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13803 * lread.c (lisp_file_lexically_bound_p): New function.
13804 (Fload): Bind Qlexical_binding.
13805 (readevalloop): Remove `evalfun' arg.
13806 Bind Qinternal_interpreter_environment.
13807 (Feval_buffer): Bind Qlexical_binding.
13808 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13810 (syms_of_lread): Declare `lexical-binding'.
13812 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13814 * keyboard.c (eval_dyn): New fun.
13815 (menu_item_eval_property): Use it.
13817 * image.c (parse_image_spec): Use Ffunctionp.
13819 * fns.c (concat, mapcar1): Accept byte-code-functions.
13821 * eval.c (Fsetq): Handle lexical vars.
13822 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13823 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13824 (FletX, Flet): Obey lexical binding.
13825 (Fcommandp): Handle closures.
13826 (Feval): New `lexical' arg.
13827 (eval_sub): New function extracted from Feval. Use it almost
13828 everywhere where Feval was used. Look up vars in lexical env.
13830 (Ffunctionp): Move from subr.el.
13831 (Ffuncall): Handle closures.
13832 (apply_lambda): Remove `eval_flags'.
13833 (funcall_lambda): Handle closures and new byte-code-functions.
13834 (Fspecial_variable_p): New function.
13835 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13836 but without exporting it to Lisp.
13838 * doc.c (Fdocumentation, store_function_docstring):
13839 * data.c (Finteractive_form): Handle closures.
13841 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13844 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13846 (exec_byte_code): New function extracted from Fbyte_code to handle new
13847 calling convention for byte-code-functions. Add new byte-codes.
13849 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13851 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13853 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13855 * xdisp.c (redisplay_internal): Fix prototype.
13857 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13859 * xdisp.c (SCROLL_LIMIT): New macro.
13860 (try_scrolling): Use it when setting scroll_limit.
13861 Limit scrolling to 100 screen lines.
13862 (redisplay_window): Even when falling back on "recentering",
13863 position point in the window according to scroll-conservatively,
13864 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13866 (try_scrolling): When point is above the window, allow searching
13867 as far as scroll_max, or one screenful, to compute vertical
13868 distance from PT to the scroll margin position. This prevents
13869 try_scrolling from unnecessarily failing when
13870 scroll-conservatively is set to a value slightly larger than the
13871 window height. Clean up the case of PT below the margin at bottom
13872 of window: scroll_max can no longer be INT_MAX. When aggressive
13873 scrolling is in use, don't let point enter the opposite scroll
13874 margin as result of the scroll.
13875 (syms_of_xdisp) <scroll-conservatively>: Document the
13876 threshold of 100 lines for never-recentering scrolling.
13878 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13880 * dispextern.h (move_it_by_lines):
13881 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13882 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13883 (message_log_check_duplicate): Remove parameters `prev_bol' and
13884 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13885 (redisplay_internal): Remove parameter `preserve_echo_area',
13886 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13888 * indent.c (Fvertical_motion):
13889 * window.c (window_scroll_pixel_based, Frecenter):
13890 Don't pass `need_y_p' to `move_it_by_lines'.
13892 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13894 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13895 steal a few bits to be more compact.
13896 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13897 Remove unneeded casts.
13899 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13901 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13903 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13904 binding" message (bug#7967).
13906 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13908 Fix more problems found by GCC 4.6.0's static checks.
13910 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13911 Remove unused local var.
13913 * editfns.c (Fmessage_box): Remove unused local var.
13915 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13916 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13917 Omit unused local vars.
13918 * window.c (shrink_windows): Omit unused local var.
13919 * menu.c (digest_single_submenu): Omit unused local var.
13920 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13921 Omit unused local var.
13923 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13924 Don't assume string length fits in int.
13925 (keyremap_step, read_key_sequence): Use size_t for sizes.
13926 (read_key_sequence): Don't check last_real_key_start redundantly.
13928 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13929 instead of alloca (Bug#8344).
13931 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13932 (Fbacktrace_frame): Don't assume nframes fits in int.
13934 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13936 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13939 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13941 * cm.c (calccost): Turn while-do into do-while, for clarity.
13943 * keyboard.c (syms_of_keyboard): Use the same style as later
13944 in this function when indexing through an array. This also
13945 works around GCC bug 48267.
13947 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13949 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13951 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13952 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13954 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13955 This avoids undefined behavior on integer overflow, and is a bit
13956 more convenient anyway since it is compared to a size_t variable.
13958 Variadic C functions now count arguments with size_t, not int.
13959 This avoids an unnecessary limitation on 64-bit machines, which
13960 caused (substring ...) to crash on large vectors (Bug#8344).
13961 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13962 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13963 All variadic functions and their callers changed accordingly.
13964 (struct gcpro.nvars): Now size_t, not int. All uses changed.

14183 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14185 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14186 unconditionally since it does the check itself.
14188 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14190 Fix more problems found by GCC 4.5.2's static checks.
14192 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14193 the first time through the loop, since we know p0 < p1 then.
14194 This also avoids a gcc -Wstrict-overflow warning.
14196 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14197 leading to a memory leak, possible in functions like
14198 load_charset_map_from_file that can allocate an unbounded number
14199 of objects (Bug#8318).
14201 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14202 that could (at least in theory) be that large.
14204 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14205 This is less likely to overflow, and avoids undefined behavior if
14206 overflow does occur. All callers changed. Use strtoul to scan
14207 for the unsigned long integer.

14224 * process.c (Fmake_network_process): Use socklen_t, not int,
14225 where POSIX says socklen_t is required in portable programs.
14226 This fixes a porting bug on hosts like 64-bit HP-UX, where
14227 socklen_t is wider than int (Bug#8277).
14228 (Fmake_network_process, server_accept_connection):
14229 (wait_reading_process_output, read_process_output):
14232 * process.c: Rename or move locals to avoid shadowing.

14244 Include tparam.h instead, since it declares them.
14245 * cm.h (PC): Remove extern decl; tparam.h now does this.
14246 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14247 * terminfo.c: Include tparam.h, to check interfaces.
14248 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14249 (tparam): Adjust signature to match interface in tparam.h;
14250 this removes some undefined behavior. Check that outstring and len
14251 are zero, which they always are with Emacs.
14252 * tparam.h (PC, BC, UP): New extern decls.
14254 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14255 (xftfont_open): Rename locals to avoid shadowing.

14273 (composition_update_it): Mark var as initialized.
14274 (find_automatic_composition): Mark vars as initialized,
14275 with a FIXME (Bug#8290).

14294 Fix pointer signedness.
14295 (alsa_choose_format): Remove unused local var.
14296 (wav_play): Initialize a variable to 0, to prevent undefined
14297 behavior (Bug#8278).
14299 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14301 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14303 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14304 clobbering (Bug#8298).
14305 * sysdep.c (sys_subshell): Likewise.
14306 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14308 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14309 This should get cleaned up, so that child_setup has the
14310 same signature on all platforms.
14312 * callproc.c (call_process_cleanup): Now static.
14313 (relocate_fd): Rename locals to avoid shadowing.
14315 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14317 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14318 not to be necessary, and produces flickering.
14320 2011-03-20 Glenn Morris <rgm@gnu.org>
14322 * config.in: Remove file.
14324 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

14369 Define only if needed.
14371 * unexelf.c (unexec): Name an expression,
14372 to avoid gcc -Wbad-function-cast warning.
14373 Use a different way to cause a compilation error if anyone uses
14374 n rather than nn, a way that does not involve shadowing.
14375 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14377 * deps.mk (unexalpha.o): Remove; unused.

14443 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14444 some of which prompt warnings from gcc -Wbad-function-cast.
14445 (Fformat_time_string, Fencode_time, Finsert_char):

14474 (Fmemory_limit): Cast sbrk's returned value to char *.
14476 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14484 to use the following functions instead of these macros.
14485 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14486 EMACS_INT, since callers assume the returned value fits in int.
14487 (upcase1): Likewise, for UPCASE_TABLE.
14488 (uppercasep, lowercasep, upcase): New static inline functions.
14489 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14499 (regex_compile, re_match_2_internal): Mark locals as initialized.
14500 (RETALLOC_IF): Define only if needed.
14501 (WORDCHAR_P): Likewise. This one is never needed, but is used
14502 only in a comment talking about a compiler bug, so put inside
14503 the #if 0 of that comment.
14504 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14505 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14532 New macros, so that the caller can use some names other than
14533 gcpro1, gcpro2, etc.
14534 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14536 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14537 argument, for consistency with GCPRO2_VAR, etc: it is now the

14540 * dired.c (directory_files_internal, file_name_completion):
14541 Rename locals to avoid shadowing.
14543 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14544 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14545 dired.c's scmp function, had undefined behavior.
14546 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14547 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14548 * buffer.h: ... to here, because these macros use current_buffer,
14549 and the new implementation with inline functions needs to have
14550 current_buffer in scope now, rather than later when the macros
14552 (downcase, upcase1): New static inline functions.
14553 (DOWNCASE, UPCASE1): Reimplement using these functions.
14554 This avoids undefined behavior in expressions like
14555 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14556 from race conditions in accessing the global variables
14557 case_temp1 and case_temp2.
14558 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14559 * lisp.h (case_temp1, case_temp2): Remove their decls.
14560 * character.h (ASCII_CHAR_P): Move from here ...

14569 (file_name_as_directory): Use const pointers when appropriate.
14570 (Fexpand_file_name): Likewise. In particular, newdir might
14571 point at constant storage, so make it a const pointer.

14575 (Fset_file_times, Finsert_file_contents, auto_save_error):

14580 to avoid shadowing.
14582 * marker.c (bytepos_to_charpos): Remove; unused.
14584 * lisp.h (verify_bytepos, count_markers): New decls,
14585 so that gcc does not warn that these functions aren't declared.
14587 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14588 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14589 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14590 (copy_text): Remove unused local var.

14595 * buffer.c (fix_overlays_before): Mark locals as initialized.
14596 (fix_start_end_in_overlays): Likewise. This function should be
14597 simplified by using pointers-to-pointers, but that's a different

14601 (report_overlay_modification): Rename locals to avoid shadowing.

14606 to suppress a gcc -Wclobbered warning that does not seem to be right.
14607 (MAXPATHLEN): Define only if needed.
14609 * process.c (serial_open, serial_configure): Move decls from here ...
14610 * systty.h: ... to here, so that they can be checked.
14612 * fns.c (get_random, seed_random): Move extern decls from here ...

14775 1152921504606846976) returns the obviously-bogus value (-948597
14776 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14777 reports time overflow. See
