127 * w32.c (init_environment): Change the default values of many
128 environment variables in dflt_envvars[] to NULL, to avoid pushing
129 them into environment when they were not already defined. Remove
130 the code that deletes site-lisp subdirectories from the default
131 value of EMACSLOADPATH, as it is no longer needed.
132 (check_windows_init_file): Now external, not static. Use
133 Vload_path as is, without adding anything, as this function is now
134 called when Vload_path is already set up.
136 * w32.h (check_windows_init_file): Add prototype.
138 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

143 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
144 any, in the DEFALT argument into the root of the Emacs build or
145 installation tree, as appropriate.
147 * callproc.c (init_callproc_1): Call decode_env_path instead of
148 doing its equivalent by hand.
149 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
150 the code that sets Vexec_path run on MS-Windows.
152 * lread.c (init_lread): Add comments to #ifdef's.
154 * msdos.c (dos_set_window_size, IT_update_begin)
155 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

162 Now constants, not macros.
164 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
166 Remove unnecessary casts involving pointers.
167 These casts are no longer needed now that we assume C89 or later,

180 (x_get_window_property, x_get_window_property_as_lisp_data):
181 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
182 Remove unnecessary pointer casts.
183 * alloc.c (record_xmalloc): New function.
184 * lisp.h (record_xmalloc): New decl.
185 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
186 more like a function. This is because the pointer cast is not
187 needed. All uses changed.
188 * print.c (print_string, print_error_message): Avoid length recalc.
190 Improve fix for macroexp crash with debugging (Bug#12118).
191 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
192 ARRAY_MARK_FLAG when checking subscripts, because ASET is
193 not supposed to be invoked from the garbage collector.
194 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
195 (gc_aset): New function, which is like ASET but can be
196 used in the garbage collector.
197 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

209 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
210 (map_w32_filename): Improve commentary. Simplify switch.
211 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
212 headers (most versions of MinGW w32api don't).
213 (get_security_info, create_symbolic_link)
214 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
216 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
217 in the argument file name.

219 GetFileAttributes fails with network-related error codes.
220 (sys_rename): Diagnose renaming of a symlink when the user doesn't
221 have the required privileges.
222 (get_file_security_desc_by_name): Renamed from
223 get_file_security_desc.
224 (stat_worker): New function, with most of the guts of 'stat', and
225 with addition of handling of symlinks and support for 'lstat'. If
226 possible, get file's attributes and security information by
227 handle, not by name. Produce S_IFLNK bit for symlinks, when
229 (stat, lstat): New functions, call 'stat_worker'.
230 (symlink, readlink, careadlinkat): Rewritten to create and resolve
231 symlinks when the underlying filesystem supports them.
233 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
235 Fix macroexp crash on Windows with debugging (Bug#12118).
236 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
237 checking subscripts; problem introduced with the recent
238 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
239 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
240 since it's used in non-static inline functions now.
242 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
243 Don't assume buffer size fits in 'int'. Remove unused local.
245 Use C99-style 'extern inline' if available.
246 * buffer.h (BUFFER_INLINE):
247 * category.h (CATEGORY_INLINE):
248 * character.h (CHARACTER_INLINE):
249 * charset.h (CHARSET_INLINE):

263 * composite.c (COMPOSITE_INLINE):
264 * dispnew.c (DISPEXTERN_INLINE):
265 * sysdep.c (SYSTIME_INLINE):
266 Define to EXTERN_INLINE, so that the corresponding functions
267 are compiled into code.
268 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
269 (INLINE_HEADER_END): New macros.
270 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

292 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
294 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
295 This how ASET and AREF are supposed to work, and makes
296 it easier to think about future improvements. See
297 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
298 * charset.h (set_charset_attr): New function.

679 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
680 (w32_kbd_patch_key, key_event): Use the codepage returned by

708 2012-07-27 Eli Zaretskii <eliz@gnu.org>
710 * alloc.c (listn): Fix the order the arguments are consed onto the
713 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
714 enumeration constants, as PURE and HEAP are too general, and clash
715 with other headers and sources, such as gmalloc.c and the
716 MS-Windows system headers. All users changed.
718 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
720 Revert last save_excursion_save and save_excursion_restore changes.

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

736 complains about the types in the unevaluated arm when the argument
737 is an integer literal.
738 (xgetint): Simplify expression.
739 * alloc.c (gdb_make_enums_visible): New constant. This ports to
740 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
741 Zaretskii in <http://bugs.gnu.org/12036#13>.
742 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
743 needed now that we have gdb_make_enums_visible.
744 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)

765 * xfns.c (syms_of_xfns): Likewise.
767 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
769 Fast save_excursion_save and save_excursion_restore.
770 * lisp.h (struct Lisp_Excursion): New data type.
771 (PVEC_EXCURSION): New pseudovector type.

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

802 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
803 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
804 not be usable in #if. This simplifies things.
806 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
808 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
810 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

813 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
814 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
815 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
816 Adjust to changes in lisp.h and emacs.c, by using
817 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
818 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
819 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
820 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
821 instead of gdb_valbits.
822 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
823 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
824 instead of gdb_array_mark_flag.
825 (xboolvector): Get size from $->size, not $->header.size.
826 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
827 (xreload, hook-run, hookpost-run): Remove.
828 * emacs.c: Include <verify.h>.
829 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
830 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
832 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
833 (gdb_USE_LSB_TAG): New enum constants.
834 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

836 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
837 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
838 as constants, so they're visible to GDB.
839 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
840 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
841 Now enum constants, not macros, so they're visible to GDB.
842 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
843 more convenient now. All uses changed.
844 (VALMASK) [USE_LSB_TAG]: Also define in this case.

855 add argument, tune behavior, and adjust all callers.
857 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
859 Use typedef for EMACS_INT, EMACS_UINT.
860 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
861 than macros. This simplifies debugging in the usual case, since
862 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
863 and it allows expressions involving EMACS_INT casts.
864 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
866 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
868 * nsterm.m (ns_read_socket): Return early if there is a modal

878 Adjust buffer text indirection counters at the end of Fkill_buffer.
879 * buffer.c (Fkill_buffer): Adjust indirection counters when the
880 buffer is definitely dead. This should really fix an issue reported
881 by Christoph Scholtes again. (Bug#12007).
882 (init_buffer_once): Initialize indirection counters of
883 buffer_defaults and buffer_local_symbols (for sanity and safety).
885 2012-07-24 Eli Zaretskii <eliz@gnu.org>
887 * xdisp.c (init_iterator): Don't compute dimensions of truncation
888 and continuation glyphs on tooltip frames, leave them at zero.
889 Avoids continued lines in tooltips. (Bug#11832)
891 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
893 Simplify copy_overlay.
894 * buffer.c (copy_overlay): Simplify. Use build_marker.

900 or invalid. (Bug#12025)
902 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
903 it signals an error when a tooltip frame is being created.
905 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
907 Cleanup miscellaneous objects allocation and initialization.
908 * alloc.c (allocate_misc): Change to static. Add argument to

916 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
918 Swap buffer text indirection counters in Fbuffer_swap_text.
919 * buffer.c (Fbuffer_swap_text): Swap indirections too.
920 This avoids crash reported by Christoph Scholtes at
921 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.

1679 * s/aix4-2.h (unix): Remove; no longer needed.
1681 EMACS_TIME simplification (Bug#11875).
1682 This replaces macros (which typically do not work in GDB)

1684 The functional style also makes code easier to read and maintain.
1685 * systime.h: Include <sys/time.h> on all hosts, not just if
1686 WINDOWSNT, since 'struct timeval' is needed in general.

1724 * nsterm.m: Include <ftoastr.h>.
1726 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1727 Prefer snprintf to strncpy.
1728 * nsterm.m (ns_term_init):
1729 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1730 * nsterm.m (ns_term_init):
1731 Avoid the need for strncpy, by using build_string or
1732 make_unibyte_string directly. Use dtoastr, not snprintf.
1733 * process.c (Fmake_network_process): Diagnose service names that
1734 are too long, rather than silently truncating them or creating
1735 non-null-terminated names.
1736 (Fnetwork_interface_info): Likewise, for interface names.

1752 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1753 where argument type is known to be a Lisp_Cons.

1769 the function is called with compile-time constant argument.
1770 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1771 argument, adjust users accordingly. Use build_pure_c_string where

1805 We include usg5-4-common.h, which defines them both.
1807 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1808 O_RDONLY already includes it).
1810 Stop ns builds setting the EMACSLOADPATH environment variable.
1811 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1812 Now it does not set EMACSLOADPATH, just returns the load-path string.
1813 * nsterm.h: Update accordingly.
1814 * lread.c [HAVE_NS]: Include nsterm.h.
1815 (init_lread) [HAVE_NS]: Use ns_load_path.

1825 (ns_init_paths): Do not set EMACSPATH.
1826 * nsterm.h (ns_exec_path): Add it.
1827 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1830 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1832 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1834 * process.c (wait_reading_process_output): 'waitchannels' was unset
1835 when read_kbd || !NILP (wait_for_cell); fix this.
1837 Add GCC-style 'const' attribute to functions that can use it.
1838 * character.h (char_resolve_modifier_mask):
1839 * keyboard.h (make_ctrl_char):
1840 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1841 (init_character_once, next_almost_prime, init_fns, init_image)
1842 (flush_pending_output, init_sound):

1847 Declare the dummy function with ATTRIBUTE_CONST.
1848 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1849 Add decls with ATTRIBUTE_CONST.
1851 Minor improvements to make_formatted_string.
1852 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1853 where int is good enough, as vsprintf returns an int.
1854 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1856 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1858 Use make_formatted_string to avoid double length calculation.
1859 * lisp.h (make_formatted_string): New prototype.
1860 * alloc.c (make_formatted_string): New function.
1861 * buffer.c (Fgenerate_new_buffer_name): Use it.

1864 * filelock.c (get_boot_time): Likewise.
1865 * frame.c (make_terminal_frame, set_term_frame_name)
1866 (x_report_frame_params): Likewise.
1867 * image.c (gs_load): Likewise.

1879 * nsterm.h (ns_etc_directory): Add it.
1880 * callproc.c [HAVE_NS]: Include nsterm.h.
1881 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1883 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1885 Move marker debugging code under MARKER_DEBUG.
1886 * marker.c (MARKER_DEBUG): Move marker debugging code under
1887 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1888 for bootstrap with --enable-checking (~3x slowdown reported
1889 by Juanma Barranquero <lekktu@gmail.com>).
1890 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1892 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1894 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1895 See <http://bugs.gnu.org/11825#29>.
1897 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1899 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1900 has no font, use the frame's font. (Bug#11813)
1901 (display_line): Add commentary about displaying truncation glyphs
1903 (produce_special_glyphs): Move here from term.c.
1905 * term.c (produce_special_glyphs): Move to xdisp.c.
1907 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1910 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1912 * xdisp.c (display_line): Avoid warning about implicit declaration
1915 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1917 * lisp.h: Remove empty conditional.
1919 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1921 * lread.c (load_path_check): Now static.
1923 Fix some minor --with-ns problems found by static checking.
1924 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1925 (x_set_font) [!HAVE_X_WINDOWS]:
1926 * image.c (xpm_load_image) [HAVE_NS]:
1927 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1928 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1929 Remove unused local.
1930 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1931 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1932 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1933 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1934 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1935 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1936 Fix pointer signedness problem.
1937 * xfaces.c (FRAME_X_FONT_TABLE):
1938 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1940 2012-07-07 Glenn Morris <rgm@gnu.org>
1942 * lread.c (load_path_check): New function, split from init_lread.
1943 (init_lread): Reorganize. Motivation:
1944 If EMACSLOADPATH is set, check/warn about that rather than the
1945 defaults, which we are not going to use. Hence we can remove
1946 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1947 Don't warn if site-lisp directories are missing.
1948 If not installed, start from a blank load-path, since
1949 PATH_LOADSEARCH refers to the eventual installation directories.
1951 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1953 Support truncation and continuation glyphs on GUI frames, when
1954 fringes are disabled. (Bug#11832)
1955 * xdisp.c (init_iterator): Get dimensions of truncation and
1956 continuation glyphs even if on GUI frames. Adjust
1957 it->last_visible_x on GUI frames when the left or right fringes,
1958 or both, are absent.
1959 (start_display, move_it_in_display_line_to): Handle the case of a
1960 GUI frame without a fringe to display continuation or truncation
1962 (insert_left_trunc_glyphs): Support GUI frames: make sure
1963 truncation glyphs overwrite enough glyphs from the current line to
1964 have sufficient space in pixels.
1965 (display_line): Support truncation and continuation glyphs on GUI
1966 frames. If some spare pixels are left on the line after inserting
1967 the truncation glyphs, fill that space with a stretch glyph of a
1968 suitably computed width.
1970 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1971 produce_glyphs, to support GUI sessions.
1973 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1975 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1977 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1979 Do not require float-time's arg to fit in time_t (Bug#11825).
1980 This works better on hosts where time_t is unsigned, and where
1981 float-time is applied to the (negative) difference between two times.
1982 * editfns.c (decode_time_components): Last arg is now double *,
1983 not int *, and means to store all the result as a double, without
1984 worrying about whether the seconds part fits in time_t.
1985 All callers changed.
1986 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1987 All callers changed.
1988 (Ffloat_time): Do not fail merely because the specified time falls
1989 outside of time_t range.
1991 2012-07-07 Glenn Morris <rgm@gnu.org>
1993 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2000 Update dependencies.
2002 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2004 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

2008 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2009 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2010 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2011 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2013 * xfont.c (compare_font_names): Redo to omit the need for casts.
2015 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2017 * xfns.c (Fx_change_window_property): Doc fix.
2018 * w32fns.c (Fx_change_window_property): Doc fix.
2020 * w32fns.c (Fx_window_property): Accept the same arguments as the
2021 X Windows version. Doc fix.
2022 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2024 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2025 Eli Zaretskii <eliz@gnu.org>
2027 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2028 Windows-specific code from nt/config.nt moved here.
2029 Obsolete settings removed.
2031 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2033 * process.c: Avoid unnecessary calls to gettime.
2034 (wait_reading_process_output): Don't get the time of day
2035 when gobbling data immediately and not waiting, as there's no need
2036 for it in that case. This removes a FIXME.
2038 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2040 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2041 is defined (Bug#11768).
2043 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2045 Fix marker debugging code.
2046 * marker.c (byte_char_debug_check): Do not perform the check
2047 if buffer is not multibyte.
2048 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2049 Call byte_char_debug_check with correct arguments.
2051 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2053 Compile marker debugging code only if ENABLE_CHECKING is defined.
2054 * marker.c (byte_char_debug_check, count_markers):
2055 Use only if ENABLE_CHECKING is defined.
2056 (byte_debug_flag): Remove.
2057 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2058 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2060 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2062 Avoid code repetition in marker-related functions.
2063 * marker.c (attach_marker): New function.
2064 (Fset_marker, set_marker_restricted, set_marker_both)
2065 (set_marker_restricted_both): Use it.
2066 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2067 Consistently rename charno to charpos.

2085 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2086 (save_restriction_save): Use build_marker.
2087 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2088 * window.c (save_window_save): Likewise.
2090 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2092 Do not use Fdelete_overlay in delete_all_overlays
2093 to avoid redundant calls to unchain_overlay.
2094 * buffer.c (drop_overlay): New function.
2095 (delete_all_overlays, Fdelete_overlay): Use it.
2096 * minibuf.c (get_minibuffer): Fix comment.
2098 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2100 Port to OpenBSD 5.1 amd64.
2101 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2102 This is needed for OpenBSD, and should be harmless on all BSD systems.
2103 Also, include <sys/sysctl.h>, as it should be available on all
2104 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2105 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2106 use p_pid member, not kp_proc.pid.
2108 2012-07-06 Glenn Morris <rgm@gnu.org>
2110 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2112 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2114 More xmalloc and related cleanup.
2115 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2116 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2119 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2120 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2121 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2122 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2123 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2125 Omit needless casts involving void * pointers and allocation.
2126 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2127 as the former is more robust if P's type is changed.
2128 Prefer xzalloc to xmalloc + memset 0.
2129 Simplify malloc-or-realloc to realloc.
2130 Don't worry about xmalloc returning a null pointer.
2131 Prefer xstrdup to xmalloc + strcpy.
2132 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2134 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2135 alloca of a constant.
2137 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2139 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2140 hscroll is larger than the line width. Fixes long and futile
2141 looping inside extend_face_to_end_of_line (on a TTY) producing
2142 glyphs that are not needed and thrown away.
2144 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2146 * marker.c (set_marker_restricted_both): Simplify by using

2162 (update_theme_scrollbar_width, xg_create_scroll_bar):
2163 Use gtk_scrollbar_new (Bug#11768).

2165 (is_box_type): New function (Bug#11768).
2166 (xg_tool_item_stale_p): Call is_box_type.
2167 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2168 with default display (Bug#11768).

2172 * xdisp.c (window_hscroll_limited): New function.
2173 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2174 coordinates when window's hscroll is set to insanely large
2177 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2179 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2246 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2247 This should be fixed in a better way; see Eli Zaretskii in
2248 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2249 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2251 * fileio.c (time_error_value): Rename from special_mtime.
2252 The old name's problems were noted by Eli Zaretskii in
2253 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2255 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2256 This variable's comment says Emacs needs at least one GDB-visible
2257 symbol of type enum pvec_type, to work around GDB problems.
2258 The symbol's value doesn't matter.
2260 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2261 that causes compilation to fail on pre-C99 compilers.
2263 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

2287 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2288 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2289 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2290 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2291 abusing vector->header.next.nbytes.
2292 (live_vector_p): Use PVEC_TYPE.
2293 (mark_object): Adapt code to extract pvectype. Use switch.
2295 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2297 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2298 Tighten new eassert a bit.
2300 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2302 Fix compilation with --enable-gcc-warnings and -O1
2304 * doprnt.c (doprnt): Change type of tem to int, initialize
2305 to avoid compiler warning. Add eassert.
2306 * search.c (simple_search): Initialize match_byte to avoid
2307 compiler warning. Add eassert.
2309 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2311 Avoid weird behavior with large horizontal scrolls.
2312 Without this change, for example, large hscroll values would
2313 mess up Emacs's display on Fedora 15 x86, presumably due to
2314 overflows in int calculations in the display code.
2315 Also, if buffers had long lines, Emacs would freeze.
2316 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2317 (set_window_hscroll): New function, containing the old guts of
2318 Fset_window_hscroll. Return the clipped value.
2319 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2320 This avoids the need to check against PTRDIFF_MAX.
2322 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2324 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2326 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2328 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2330 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2331 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2332 since GCC 4.4.6 issues a bogus warning for them.
2334 Fix bugs in file timestamp newness comparisons.
2335 * fileio.c (Ffile_newer_than_file_p):
2336 * lread.c (Fload): Use full timestamp resolution of files,
2337 not just the 1-second resolution, so that files that are only
2338 slightly newer still count as newer.
2339 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2340 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2342 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2344 * fileio.c: Improve handling of file time marker. (Bug#11852)
2345 (special_mtime): New function.
2346 (Finsert_file_contents, Fverify_visited_file_modtime):
2347 Use it to set special mtime values consistently.
2349 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2351 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2352 marker for non-existing file. (Bug#11852)
2354 2012-07-03 Glenn Morris <rgm@gnu.org>
2356 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2357 and did not make it into globals.h).
2359 2012-07-03 Tom Tromey <tromey@redhat.com>
2361 * window.c (Fset_window_margins, Fset_window_fringes)
2362 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2363 * textprop.c (Fprevious_property_change): No longer static.
2364 * syntax.c (Fsyntax_table_p): No longer static.
2365 * process.c (Fget_process, Fprocess_datagram_address): No longer

2375 * doc.c (Fdocumentation_property, Fsnarf_documentation):
2377 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
2379 * dired.c (Ffile_attributes): No longer static.
2380 * composite.c (Fcomposition_get_gstring): No longer static.
2381 * callproc.c (Fgetenv_internal): No longer static.
2383 * ccl.h: Remove EXFUNs.
2384 * buffer.h: Remove EXFUNs.
2385 * dispextern.h: Remove EXFUNs.
2386 * intervals.h: Remove EXFUNs.
2387 * fontset.h: Remove EXFUN.
2388 * font.h: Remove EXFUNs.
2389 * dosfns.c (system_process_attributes): Remove EXFUN.
2390 * keymap.h: Remove EXFUNs.
2391 * lisp.h: Remove EXFUNs.
2392 * w32term.h: Remove EXFUNs.
2393 * window.h: Remove EXFUNs.
2394 * xsettings.h: Remove EXFUN.
2395 * xterm.h: Remove EXFUN.
2397 2012-07-03 Glenn Morris <rgm@gnu.org>
2399 * lisp.h (Frandom): Make it visible to C.
2400 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2401 buffer for invisible buffers. (Bug#1229)
2403 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2405 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2406 values which aren't power of 2.
2407 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2408 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2411 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2413 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2415 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2417 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2419 * alloc.c (allocate_vector_block): Remove redundant
2420 calls to mallopt if DOUG_LEA_MALLOC is defined.
2421 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2422 avoid calls to mallopt if zero_vector is returned.
2424 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2426 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2427 is enabled, avoid dereferencing NULL current_sblock if
2430 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2432 Cleanup basic buffer management.
2433 * buffer.h (struct buffer): Change layout to use generic vector
2434 marking code. Fix some comments. Change type of 'clip_changed'
2435 to bitfield. Remove unused #ifndef old.
2436 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2437 (GET_OVERLAYS_AT): Fix indentation.
2438 (for_each_per_buffer_object_at): New macro.
2439 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2440 (Fbuffer_local_variables): Use it.
2441 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2442 * alloc.c (allocate_buffer): Adjust to match new layout of
2443 struct buffer. Fix comment.
2444 (mark_overlay): New function.
2445 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2446 Lisp area of struct buffer.
2447 (mark_object): Use it. Adjust marking of misc objects
2448 and related comments.
2450 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2452 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2453 wrapper that is not needed because the wrapped code is a no-op (zero
2454 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2455 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2457 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2459 * alloc.c (mark_buffer): Simplify. Remove prototype.
2460 (mark_object): Add comment. Reorganize marking of vector-like
2461 objects. Use CHECK_LIVE for all vector-like objects except buffers
2462 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2463 redundant calls to mark_vectorlike for bool vectors.
2465 2012-06-30 Glenn Morris <rgm@gnu.org>
2467 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2469 * epaths.in (PATH_SITELOADSEARCH): New.
2470 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2471 This is rather than relying on --enable-locallisppath elements
2472 having "site-lisp" in their names. (Bug#10208#25, 11658)
2474 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2476 * w32proc.c (sys_select): Accept and ignore one more argument.
2478 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2480 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2481 (pselect) [!MS_DOS]: Redirect to sys_select.
2483 * sysdep.c: Don't include dos.h and dosfns.h.
2485 * process.c (sys_select):
2486 * msdos.c (sys_select): Accept one more argument and ignore it.
2488 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2489 adapt data types and code to that.
2492 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2493 which clashes with the gnulib function of the same name.
2495 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2497 * font.c (font_style_to_value, font_style_symbolic)
2498 (font_prop_validate_style): Add type checks for values in
2501 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2503 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2506 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2508 * xdisp.c (try_window_id): Undo last change.
2510 * w32.c (getwd): Adjust commentary about startup_dir.
2511 (init_environment): Always call sys_access, even in non-MSVC
2512 builds. Don't chdir to the directory of the Emacs executable.
2513 This undoes code from 1997 which was justified by the need to
2514 "avoid conflicts when removing and renaming directories". But its
2515 downside was that every relative file name was being interpreted
2516 relative to the directory of the Emacs executable, which can never
2517 be TRT. In particular, it broke sys_access when called with
2518 relative file names.
2519 (sys_access): Map GetLastError to errno.
2521 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2523 * window.h (struct window): Change type of 'fringes_outside_margins'
2524 to bitfield. Fix comment. Adjust users accordingly.

2527 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2530 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2532 * gnutls.c (emacs_gnutls_handshake):
2533 Add QUIT to make the loop interruptible.
2535 2012-06-29 Glenn Morris <rgm@gnu.org>
2537 * charset.c (init_charset): Make lack of etc/charsets fatal.
2539 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2541 * editfns.c (region_limit): Fix type mismatch.
2543 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2545 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2546 undefined. Convert from xassert to eassert.
2547 * nsmenu.m: Convert from xassert to eassert.
2548 * nsterm.m: Likewise.
2550 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2552 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2554 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2556 Avoid integer overflow on scroll-left and scroll-right.
2557 * window.c (HSCROLL_MAX): New macro.
2558 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2559 overflow when requested scroll falls outside ptrdiff_t range.
2561 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2563 * window.h (struct window): Change type of 'hscroll',
2564 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2565 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2566 Adjust users accordingly.
2567 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2568 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2569 from EMACS_INT to ptrdiff_t.
2570 (make_window): Omit redundant initialization.
2572 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2576 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2578 * window.h (struct window): Change type of 'use_time' and
2579 'sequence_number' from Lisp_Object to int.

2589 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2590 adjust comments accordingly.

2639 * alloc.c (allocate_string_data): Remove dead code.
2640 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2641 avoid GCC warning about unused macro.
2643 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2645 * alloc.c (allocate_string): Omit intervals initialization.
2646 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2647 as in make_pure_string and make_pure_c_string.
2649 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2651 * alloc.c (allocate_string): Fix last change.
2653 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2703 * alloc.c: Remove build_string.
2704 * lisp.h: Define build_string as static inline. This provides
2705 a better opportunity to optimize away calls to strlen when the
2706 function is called with compile-time constant argument.
2707 * image.c (imagemagick_error): Convert to build_string.
2708 * w32proc.c (sys_spawnve): Likewise.
2709 * xterm.c (x_term_init): Likewise.
2711 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2713 Use sprintf return value instead of invoking strlen on result.
2714 In the old days this wasn't portable, since some sprintf
2715 implementations returned char *. But they died out years ago and
2716 Emacs already assumes sprintf returns int.
2717 Similarly for float_to_string.
2718 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2719 * ccl.c (ccl_driver):
2720 * character.c (string_escape_byte8):

2723 * print.c (print_object):
2724 * xdisp.c (message_dolog):
2725 * xfns.c (syms_of_xfns):
2726 Use sprintf or float_to_string result to avoid need to call strlen.
2727 * data.c (Fnumber_to_string):
2728 Use make_unibyte_string, since the string must be ASCII.
2729 * lisp.h, print.c (float_to_string): Now returns int length.
2730 * term.c (produce_glyphless_glyph):
2731 Use sprintf result rather than recomputing it.
2733 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2734 * Makefile.in (ALL_CFLAGS):
2735 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2741 strcasecmp if available.

2757 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
2759 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2760 sprintf already null-terminates its output.

2764 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2766 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2769 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2771 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2772 instead of truncating it to 63 (admittedly a generous limit).
2774 * process.c: Fix spelling and caps in comments.
2776 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2778 * emacs.c (setpgrp): Remove definition, unused.

2788 (SYSTIME_H): Add nt/inc/sys/time.h.
2790 * systime.h [WINDOWSNT]: Include sys/time.h.

2902 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2904 Support higher-resolution time stamps (Bug#9000).
2905 The time stamps are only nanosecond-resolution at the C level,
2906 since that's the best that any real-world system supports now.
2907 But they are picosecond-resolution at the Lisp level, as that's
2908 easy, and leaves room for future OS improvements.
2910 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2913 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2914 Don't get current time unless it's needed.
2916 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2917 now provides it if it's absent.
2918 (start_atimer): Port to higher-res time stamps.
2919 Check for time stamp overflow. Don't get current time more
2920 often than is needed.
2922 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2923 Include systime.h, not time.h.
2924 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2926 * dired.c: Include stat-time.h.
2927 (Ffile-attributes): File times now have higher resolution.

2930 (struct image): Timestamp now has higher resolution.
2932 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2933 has at least microseconds now. All uses removed.
2934 (update_frame, update_single_window, update_window, update_frame_1)
2935 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2937 * editfns.c (time_overflow): Now extern.
2938 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2939 (float-time, Fformat_time_string, Fcurrent_time_string)
2940 (Fcurrent_time_zone): Accept and generate higher-resolution

2943 (decode_time_components, lisp_seconds_argument): New functions.
2944 (make_time): Now static.
2945 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2946 Report an error if the time is invalid, rather than having the caller
2949 * fileio.c: Include <stat-time.h>
2950 (Fcopy_file): Copy higher-resolution time stamps.
2951 Prefer to set the time stamp via a file descriptor if that works.
2952 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2953 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2954 (Fvisited_file_modtime, Fset_visited_file_modtime):
2955 Support higher-resolution time stamps.
2957 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2959 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2961 * image.c (prepare_image_for_display, clear_image_cache)
2962 (lookup_image): Port to higer-resolution time stamps.
2964 * keyboard.c (start_polling, bind_polling_period):
2965 Check for time stamp overflow.
2966 (read_char, kbd_buffer_get_event, timer_start_idle)
2967 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2968 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2969 Port to higher-resolution time stamps. Do not assume time_t is signed.
2970 (decode_timer): New function. Timers are now vectors of length 9,
2971 not 8, to accommodate the picosecond component.
2972 (timer_check_2): Use it.
2974 * nsterm.m (select_timeout, timeval_subtract): Remove.
2975 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2976 as they're a bit more accurate and handle overflow better.
2977 (ns_select): Change prototype to be compatible with pselect.
2978 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2979 * nsterm.h (ns_select): Adjust prototype.
2981 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2982 us-resolution time stamps.
2983 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2985 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2987 * lisp.h (time_overflow): New decl.
2988 (wait_reading_process_output): First arg is now intmax_t, not int,
2989 to accommodate larger waits.
2991 * process.h (struct Lisp_Process.read_output_delay):
2992 Now counts nanoseconds, not microseconds.
2993 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2995 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2996 (wait_reading_process_output):
2997 Port to ns-resolution time stamps.
2998 (Faccept_process_output, wait_reading_process_output):
2999 Check for time stamp overflow. Do not assume time_t is signed.
3000 (select_wrapper): Remove; we now use pselect.
3001 (Fprocess_attributes): Now generates ns-resolution time stamps.
3003 * sysdep.c: Include utimens.h. Don't include utime.h
3004 or worry about struct utimbuf; gnulib does that for us now.
3005 (gettimeofday): Remove; gnulib provides a substitute.
3006 (make_timeval): New function.
3007 (set_file_times): Now sets ns-resolution time stamps.
3008 New arg FD; all uses changed.
3009 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3010 (system_process_attributes):
3011 Now returns ns-resolution time stamp. All uses changed.
3012 Check for time stamp overflow.
3014 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3015 provides a substitute now.
3017 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3018 since it guarantees struct timespec.
3019 (EMACS_TIME): Now struct timespec, so that we can support
3020 ns-resolution time stamps.
3021 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3022 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3023 (EMACS_USECS): Remove.
3024 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3025 so multiply the arg by 1000 before storing it.
3026 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3028 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3029 Port to ns-resolution time stamps.
3030 (EMACS_TIME_NEG_P): Remove; replaced by....
3031 (EMACS_TIME_SIGN): New macro.
3032 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3033 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3034 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3035 (make_timeval, make_lisp_time, decode_time_components): New decls.
3036 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3037 that it mishandled time_t overflow. You can't compare by subtracting!
3038 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3039 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3041 * term.c: Include <sys/time.h>.
3042 (timeval_to_Time): New function, for proper overflow wraparound.
3043 (term_mouse_position, term_mouse_click): Use it.
3045 * undo.c (record_first_change): Support higher-resolution time stamps
3047 (Fprimitive_undo): Use them when restoring time stamps.
3049 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3050 (w32_get_internal_run_time):
3051 Port to higher-resolution Emacs time stamps.
3052 (ltime): Now accepts single 64-bit integer, as that's more convenient
3055 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3057 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3058 for compatibility with pselect. Support ns-resolution time stamps.
3060 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3062 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3063 Check for time stamp overflow, and support ns-resolution time stamps.
3065 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3066 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3067 (timeval_subtract): Remove; no longer needed.
3068 (XTflash, XTring_bell, x_wait_for_event):
3069 Port to ns-resolution time stamps. Don't assume time_t is signed.
3071 2012-06-22 Chong Yidong <cyd@gnu.org>

3075 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3077 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3078 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3079 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3080 staticidx goes up to 1597 out of 1600 = 0x640.)
3082 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3084 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3085 Otherwise, the umask might be mistakenly 0 while handling input signals.
3087 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3089 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3095 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3096 access to `contents' member of Lisp_Vector objects with AREF and ASET
3099 2012-06-19 Chong Yidong <cyd@gnu.org>
3101 * frame.c (delete_frame): When selecting a frame on a different

3106 (unwind_format_mode_line): Restore them.
3107 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3109 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3110 since tty frames can be explicitly named.
3111 (prepare_menu_bars): Likewise.
3113 * term.c (Ftty_top_frame): New function.
3115 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

3118 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3119 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3120 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3121 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3122 (METER_1, METER_2): Simplify.
3124 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3126 * data.c (Fdefalias): Return `symbol' (bug#11686).
3128 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3130 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3131 gets killed during executing of this function (Bug#11665).
3132 Try to always return Qt when the buffer has been actually killed.
3133 (Vkill_buffer_query_functions): In doc-string say that functions
3134 run by this hook should not change the current buffer.
3136 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3138 Fix recently-introduced process.c problems found by static checking.
3139 * process.c (write_queue_push, write_queue_pop, send_process):

3156 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3158 * lisp.h (eassert): Assume C89 or later.
3159 This removes the need for CHECK.
3160 (CHECK): Remove. Its comments about always evaluating its
3161 argument were confusing, as 'eassert' typically does not evaluate
3164 * coding.c (produce_chars): Use ptrdiff_t, not int.
3166 * xterm.c (x_draw_underwave): Check for integer overflow.
3167 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3352 code works fine either way, and efficiency is not a concern here,
3353 as the union type is for debugging, not for production.
3354 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3355 Use an inline function on all platforms when using the union type,
3356 since this is simpler and 'static inline' can be used portably
3358 (LISP_INITIALLY_ZERO): New macro.
3359 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3360 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3498 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3500 * doprnt.c (doprnt): Truncate multibyte char correctly.
3501 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3502 would mishandle a string argument "Xc" if X was a multibyte
3503 character of length 2: it would truncate after X's first byte
3504 rather than including all of X.
3506 2012-06-06 Chong Yidong <cyd@gnu.org>
3508 * buffer.c (word_wrap): Doc fix.

3557 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3558 Convert pctcpu and pctmem to Lisp float properly.
3559 Let the compiler fold better, as 100.0/0x8000 is exact.
3561 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3563 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3566 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

3587 and 'double' in a couple of places.
3589 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3591 * xdisp.c (handle_stop): Detect whether we have overlay strings
3592 loaded by testing it->current.overlay_string_index to be
3593 non-negative, instead of checking whether n_overlay_strings is
3594 positive. (Bug#11587)
3596 2012-05-31 Chong Yidong <cyd@gnu.org>
3598 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

3606 maybe_unify_char, which was the cause of relocation of buffer text
3609 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3611 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3612 for the duration of call to load_charset, to avoid problems with
3613 callers of maybe_unify_char that access buffer text through C
3616 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3617 decrement the inhibition flag, instead of just setting or
3620 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3622 Remove obsolete '#define static' cruft.
3623 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

3626 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3627 (gray_bitmap_bits): Remove; no longer needed.
3628 All uses replaced with definiens.

3672 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3673 Bug#9642, but explicitly check that the buffer the overlay would
3674 be moved to is live and rearrange lines to make sure that errors
3675 will not put the overlay in an inconsistent state.
3676 (Fdelete_overlay): Cosmetics.
3678 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3680 * w32term.c (my_bring_window_to_top): New function.

3737 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3739 * search.c (search_buffer): Use it to inhibit relocation of buffer
3740 text while re_search_2 is doing its job, because re_search_2 is
3741 passed C pointers to buffer text. (Bug#11519)
3743 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3746 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3747 state after an additional call to move_it_in_display_line_to, keep
3748 the values of it->max_ascent and it->max_descent found for the

3751 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

3756 Fix coding-related core dumps with gcc -ftrapv.
3757 The code was computing A - B, where A and B are pointers, and B is
3758 random garbage. This can lead to core dumps on platforms that
3759 have special pointer registers, and it also leads to core dumps on
3760 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3761 A - B only when B is initialized properly.
3762 * coding.c (coding_set_source, coding_set_destination): Return void.
3763 (coding_change_source, coding_change_destinations): New functions,
3764 with the old behaviors of coding_set_source and coding_set_destination.

3782 * w32inevt.c: Include termchar.h and window.h.
3783 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3784 moves, call note_mouse_highlight. If help_echo changed, call
3785 gen_help_event to produce help-echo message in the echo area.
3786 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3789 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3791 * lread.c (read1): Simplify slightly to avoid an overflow warning
3792 with GCC 4.7.0 on x86-64.
3794 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3796 * bidi.c (bidi_mirror_char): Revert last change: an int is
3797 definitely wide enough here.
3799 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

3813 Use int, not EMACS_INT, where int is wide enough.
3814 (inhibit_garbage_collection, Fgarbage_collect):

3834 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3835 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3836 (validate_region): Omit unnecessary test for b <= e,
3837 since that's guaranteed by the previous test.
3838 (adjust_overlays_for_delete): Avoid pos + length overflow.
3839 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3840 (report_overlay_modification):
3841 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3842 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3851 not int, to avoid needless 32-bit limit on 64-bit hosts.
3852 (exec_byte_code): Use tighter memory-full test, one that checks
3853 for alloca overflow. Don't compute the address of the object just
3854 before an array, as that's not portable. Use EMACS_INT, not
3855 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3856 * callint.c (Fcall_interactively):
3857 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3869 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3870 (casify_object): Avoid integer overflow when overallocating buffer.
3871 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3872 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3873 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3874 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3875 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3876 integers are now checked earlier. All uses replaced with XINT.
3878 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3879 For CCL_MapSingle, check that content and value are in int range.
3880 (ccl_driver, Fregister_code_conversion_map):
3881 Check that Vcode_version_map_vector is a vector.
3882 (resolve_symbol_ccl_program): Check that vector header is in range.
3883 Always copy the vector, so that we can check its contents reliably
3884 now rather than having to recheck each instruction as it's being
3885 executed. Check that vector words fit in 'int'.
3886 (ccl_get_compiled_code, Fregister_ccl_program)
3887 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3888 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3889 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3890 contents are in range.
3891 (Fccl_execute_on_string): Check that status is in range.
3892 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3893 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3894 Accept and return EMACS_INT, not int, because callers can pass values

3901 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3903 avoid mishandling large integers.

3914 Don't rely on undefined behavior with signed left shift overflow.
3915 Don't assume unsigned int fits into fixnum, or that fixnum fits
3916 into unsigned int. Don't require max_code to be a valid fixnum;
3917 that's not true for gb10830 4-byte on a 32-bit host. Allow
3918 invalid_code to be a cons, for the same reason. Require code_offset
3919 to be a character. Avoid int overflow if max_char is close
3921 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3922 this is intended anyway and avoids some undefined behavior.
3923 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3924 INDEX_TO_CODE_POINT, as that's what it expects.
3925 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3926 * charset.h (DECODE_CHAR): Return int, not unsigned;
3927 this is what was intended anyway, and it avoids undefined behavior.
3928 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3929 integer-overflow issues.
3930 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3931 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3932 where the argument is EMACS_INT, and this behavior is not intended.
3933 * chartab.c (Fmake_char_table, Fset_char_table_range)
3934 (uniprop_get_decoder, uniprop_get_encoder):
3935 Don't assume fixnum fits in int.
3936 * cmds.c (move_point): New function, that does the gist of
3937 Fforward_char and Fbackward_char, but does so while checking
3938 for integer overflow more accurately.
3939 (Fforward_char, Fbackward_char): Use it.
3940 (Fforward_line, Fend_of_line, internal_self_insert)
3941 (internal_self_insert):
3942 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4644 define them any more.

4652 * s/ms-w32.h (DATA_START):
4653 Move here from removed file m/intel386.h.

4708 2012-05-17 Juri Linkov <juri@jurta.org>

4712 (Fword_search_forward_lax): Move functions to isearch.el
4713 (bug#10145, bug#11381).
4715 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4717 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).

4723 2012-05-14 Glenn Morris <rgm@gnu.org>
4725 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4726 Put "libexec" before "bin", for the sake of init_callproc_1.
4728 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4730 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4732 * unexaix.c: Port to more-recent AIX compilers.
4733 (report_error, report_error_1, make_hdr, copy_sym)
4734 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4735 Make arguments const char *, not char *, to avoid violations of C
4736 standard and to fix some AIX warnings reported by Gilles Pion.
4738 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4740 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4741 already have overlays loaded.
4742 (handle_single_display_spec): Before returning without displaying
4743 fringe bitmap, synchronize the bidi iterator with the main display
4744 iterator, by calling iterate_out_of_display_property.
4745 (iterate_out_of_display_property): Detect buffer iteration by
4746 testing that it->string is a Lisp string.
4747 (get_next_display_element): When the current object is exhausted,
4748 and there's something on it->stack, call set_iterator_to_next to
4749 proceed with what's on the stack, instead of returning zero.
4750 (set_iterator_to_next): If called at the end of a Lisp string,
4751 proceed to consider_string_end without incrementing string
4752 position. Don't increment display vector index past the end of
4753 the display vector. (Bug#11417)
4754 (pos_visible_p): Don't report a position visible when move_it_to
4755 stopped at the last line of window, which happens to be scanned
4756 backwards by the bidi iteration. (Bug#11464)
4758 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4760 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4761 and right-margin display specs even if the spec is invalid or we
4762 are on a TTY, and thus unable to display on the fringes.
4763 That's because the text with the property will not be displayed anyway,
4764 so we need to signal to the caller that this is a "replacing"
4765 display spec. This fixes display when the spec is invalid or we
4768 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4770 * unexaix.c (make_hdr): Fix typo in prototype.
4771 This bug broke the build on AIX. Problem reported by Gilles Pion.
4773 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4775 * keyboard.c (kbd_buffer_get_event): Read special events also in
4776 batch mode. (Bug#11415)
4778 2012-05-12 Glenn Morris <rgm@gnu.org>

4786 2012-05-12 Glenn Morris <rgm@gnu.org>
4788 * Makefile.in (MKDIR_P): New, set by configure.
4789 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4791 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4793 Remove unused function hourglass_started.
4794 * dispextern.h (hourglass_started):

4801 Update dependencies.
4803 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4805 * xgselect.c (xg_select): Put maxfds+1 into a var.
4806 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4808 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4810 2012-05-10 Dave Abrahams <dave@boostpro.com>
4812 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4813 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4815 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4817 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4818 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4819 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4820 Initialize xd_registered_buses.
4822 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4824 Untag more efficiently if USE_LSB_TAG.
4825 This is based on a proposal by YAMAMOTO Mitsuharu in
4826 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4827 For an admittedly artificial (nth 8000 longlist) benchmark on
4828 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4829 Emacs's overall text size by 1%.
4830 * lisp.h (XUNTAG): New macro.
4831 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4832 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4833 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4834 * eval.c (Fautoload):
4835 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4836 * frame.h (XFRAME): Use XUNTAG.
4838 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4839 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4840 Remove unportable assumptions about print widths of types like
4842 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4843 intptr_t when converting between pointer and integer, to avoid GCC
4844 warnings about wrong width.
4846 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4848 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4849 stack for each reader_thread, instead of defaulting to 8MB
4850 determined by the linker. This avoids failures in creating
4851 subprocesses on Windows 7, see the discussion in this thread:

4856 Fix up display of the *Minibuf-0* buffer in the mini window.
4857 * keyboard.c (read_char): Don't clear the echo area if there's no
4859 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4860 contents of *Minibuf-0*) if there's no message displayed in its stead.
4862 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4864 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4867 2012-05-06 Chong Yidong <cyd@gnu.org>
4869 * lisp.mk (lisp): Update.
4871 2012-05-05 Jim Meyering <meyering@redhat.com>
4873 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4875 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4877 * data.c (PUT_ERROR): New macro.
4878 (syms_of_data): Use it. Add new error type `user-error'.
4879 * undo.c (user_error): New function.
4880 (Fprimitive_undo): Use it.
4881 * print.c (print_error_message): Adjust print style for `user-error'.
4882 * keyboard.c (user_error): New function.
4883 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4885 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4887 Do not limit current-time-string to years 1000..9999.
4888 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4889 (Fcurrent_time_string): Support any year that is supported by the
4890 underlying localtime representation. Don't use asctime, as it
4891 has undefined behavior for years outside the range -999..9999.
4893 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4895 Fix race conditions involving setenv, gmtime, localtime, asctime.
4896 Without this fix, interrupts could mess up code that uses these
4897 nonreentrant functions, since setting TZ invalidates existing
4898 tm_zone or tzname values, and since most of these functions return
4899 pointers to static storage.
4900 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4901 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4902 Grow the critical sections to include not just invoking
4903 localtime/gmtime, but also accessing these functions' results
4904 including their tm_zone values if any, and any related TZ setting.
4905 (format_time_string): Last arg is now struct tm *, not struct tm **,
4906 so that the struct tm is saved in the critical section.
4907 All callers changed. Simplify allocation of initial buffer, partly
4908 motivated by the fact that memory allocation needs to be outside
4909 the critical section.
4911 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4913 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4914 with RESET_INTERVAL.
4916 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4917 Remove duplicated buffer name initialization.
4919 2012-05-02 Jim Meyering <jim@meyering.net>
4921 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4923 * xfns.c (x_window): Use xstrdup (Bug#11375).
4925 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4927 * xdisp.c (pos_visible_p): If already at a newline from the
4928 display string before the 'while' loop, don't walk back the glyphs
4929 from it3.glyph_row. Solves assertion violation when the display
4930 string begins with a newline (egg.el). (Bug#11367)
4932 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4934 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4937 2012-05-01 Glenn Morris <rgm@gnu.org>
4939 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4940 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4941 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4942 All were removed before 23.1.
4944 * dispnew.c: Remove HAVE_LIBNCURSES test;
4945 it is always true on relevant platforms.
4947 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4948 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4950 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4952 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4954 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4955 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4958 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4960 Do not avoid creating empty evaporating overlays (Bug#9642).
4961 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4962 That is, do not delete an evaporating overlay if it becomes
4963 empty after its bounds are adjusted to fit within its buffer.
4964 This fix caused other problems, and I'm reverting it until we get
4965 to the bottom of them.
4967 2012-04-27 Chong Yidong <cyd@gnu.org>
4969 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4971 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4973 * xdisp.c (pos_visible_p): If the window start position is beyond
4974 ZV, start the display from buffer beginning. Prevents assertion
4975 violation in init_iterator when the minibuffer window is scrolled
4978 * window.c (window_scroll_pixel_based): Likewise.
4980 2012-04-27 Chong Yidong <cyd@gnu.org>
4982 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4984 2012-04-27 Glenn Morris <rgm@gnu.org>
4986 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4987 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4989 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4991 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4992 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4994 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4996 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4997 display element, check also the underlying string or buffer
4998 character. (Bug#11341)
5000 * w32menu.c: Include w32heap.h.
5001 (add_menu_item): If the call to AppendMenuW (via
5002 unicode_append_menu) fails, disable Unicode menus only if we are
5003 running on Windows 9X/Me.
5005 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5007 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5008 (xgetint): Add missing shift for LSB tags.
5010 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5012 * keyboard.c (read_char): Don't wipe echo area for select window
5013 events: These might get delayed via `mouse-autoselect-window'
5016 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5018 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5019 manipulation of :loaded-from data.
5021 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5023 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5024 now a cons (bug#11311).
5026 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5028 Do not create empty overlays with the evaporate property (Bug#9642).
5029 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5030 if it becomes empty after its bounds are adjusted to fit within
5031 its buffer. Without this fix, in a nonempty buffer (let ((o
5032 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5033 yields an empty overlay that has the evaporate property, which is
5034 not supposed to happen.
5036 Fix minor GTK3 problems found by static checking.
5037 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5038 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5039 (struct _EmacsFixedClass, emacs_fixed_get_type):

5047 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5048 (EMACS_FIXED_GET_CLASS): Remove; unused.
5049 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5051 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5052 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5054 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5056 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5057 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5058 (__malloc_size_t, __malloc_ptrdiff_t):
5059 Remove. All uses removed, replaced by the definiens if needed,
5060 since we can assume C89 or better now.
5061 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

5071 Define using prototypes, not old style.
5072 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5073 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5074 (align): Don't assume that signed integer overflow wraps around.
5075 Omit unused local var.
5076 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

5253 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5254 [REL_ALLOC]: ... to here, to check interface.
5255 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5256 Remove decls. This fixes an "It stinks!".
5258 * alloc.c (which_symbols): Fix alignment issue / type clash.
5260 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5262 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5280 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5281 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5282 no longer the default.
5283 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5285 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5308 2012-04-11 Daniel Colascione <dancol@dancol.org>
5310 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5311 against is gone. It's better to use vfork now so that when Cygwin
5312 gains a new, working vfork, we use it automatically (bug#10398).
5314 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5316 * window.c (save_window_save): Obey window-point-insertion-type.

5326 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5328 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5329 (force_quit_count): New var.
5330 (handle_interrupt): Use it.
5332 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5334 * w32.c (w32_delayed_load): Record the full path of the library
5335 being loaded (bug#10424).
5337 2012-04-09 Glenn Morris <rgm@gnu.org>
5339 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5340 not just in the obarray, before snarfing them. (Bug#11036)
5342 * Makefile.in ($(leimdir)/leim-list.el):
5343 Pass EMACS rather than BUILT_EMACS.
5345 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5347 * process.c (make_process):
5348 * process.h: Add integer `gnutls_handshakes_tried' member to
5351 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5352 Add convenience `GNUTLS_LOG2i' macro.
5354 * gnutls.c (gnutls_log_function2i): Convenience log function.
5355 (emacs_gnutls_read): Use new log functions,
5356 `gnutls_handshakes_tried' process member, and
5357 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5358 attempts per process (connection).
5360 2012-04-09 Chong Yidong <cyd@gnu.org>
5362 * eval.c (Fuser_variable_p, user_variable_p_eh)

5364 (Fdefvar): Caller changed.
5366 * callint.c (Finteractive, Fcall_interactively):
5367 * minibuf.c (Fread_variable): Callers changed.
5369 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5371 * xdisp.c (set_cursor_from_row): If the display string appears in
5372 the buffer at position that is closer to point than the position
5373 after the display string, display the cursor on the first glyph of
5374 the display string. Fixes cursor display when a 'display' text
5375 property immediately follows invisible text. (Bug#11094)
5377 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5379 composite.c: use 'double' consistently
5380 * composite.c (get_composition_id): Use 'double' consistently
5381 instead of converting 'float' to 'double' and vice versa; this is
5382 easier to understand and avoids a GCC warning.
5384 2012-04-09 Glenn Morris <rgm@gnu.org>
5386 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5387 preparation for dumping it with emacs. (Bug#4789)
5388 (leimdir): New variable.
5389 ($(leimdir)/leim-list.el): New rule.
5390 (emacs$(EXEEXT)): Depend on leim-list.el.

5394 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
5396 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5398 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5401 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5403 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5404 Remove unused local variable.
5406 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5408 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5409 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5410 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5411 objects, as mark_maybe_pointer will catch them otherwise.
5412 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5413 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5415 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5417 Fix typo that broke non-Windows builds.
5418 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5420 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5422 Support building on MS-Windows with libxml2.
5424 * makefile.w32-in (OBJ2): Add xml.$(O).
5425 (GLOBAL_SOURCES): Add xml.c.
5426 ($(BLD)/xml.$(O)): New dependency list.
5428 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5429 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5430 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5431 [!WINDOWSNT]: New macros.
5432 (init_libxml2_functions, libxml2_loaded_p): New functions.
5433 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5434 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5435 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5436 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5438 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5439 Call init_libxml2_functions before calling libxml2 functions.
5440 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5442 * emacs.c: Don't include libxml/parser.h.
5443 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5444 xmlCleanupParser directly.
5446 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5448 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5450 * indent.c (Fvertical_motion): If there is a display string at
5451 point, use it.vpos to compute how many lines to backtrack after
5452 move_it_to point. (Bug#11133)
5454 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5456 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5457 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5458 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5459 macros related to unification of CJK characters. For the details,
5460 see the discussion following the message here:
5461 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5463 2012-04-04 Chong Yidong <cyd@gnu.org>
5465 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5467 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5469 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5470 instead of alloca. (Bug#11138)
5472 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5474 * w32menu.c (is_simple_dialog): Properly check lisp types.
5477 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5479 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5480 position we get to after a call to move_it_to fails the
5481 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5482 only if we wind up in a string from display property. (Bug#11063)
5484 * window.c (Fdelete_other_windows_internal): Invalidate the row
5485 and column information about mouse highlight, so that redisplay
5486 restores it after reallocating the glyph matrices. (Bug#7464)
5488 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5489 string comes from a `display' text property, use the buffer
5490 position of that property as if we actually saw that position in
5492 (move_it_by_lines): Remove the assertion that
5493 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5494 violated when there's a before-string at the beginning of a line.
5497 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5499 * xdisp.c (append_space_for_newline): If the default face was
5500 remapped, use the remapped face for the appended newline.
5501 (extend_face_to_end_of_line): Use the remapped default face for
5502 extending the face to the end of the line.
5503 (display_line): Call extend_face_to_end_of_line when the default
5504 face was remapped. (Bug#11068)
5506 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5508 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5510 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5512 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5514 2012-03-27 Glenn Morris <rgm@gnu.org>
5516 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5519 2012-03-26 Kenichi Handa <handa@m17n.org>
5521 * dispextern.h (struct glyph): Fix previous change. Change the
5522 bit length of glyphless.ch to 25 (Bug#11082).
5524 2012-03-26 Chong Yidong <cyd@gnu.org>
5526 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5527 (command_loop_1): Use it; inhibit selection update for
5528 handle-select-window too (Bug#8996).
5530 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5532 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5534 2012-03-25 Kenichi Handa <handa@m17n.org>
5536 * dispextern.h (struct glyph): Change the bit length of
5537 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5539 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5541 * s/ms-w32.h (tzname): Include time.h before redirecting to
5542 _tzname. Fixes the MSVC build. (Bug#9960)
5544 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5546 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5549 * xterm.c (XTread_socket): Only modify handling_signal if
5550 !SYNC_INPUT. (Bug#11080)
5552 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5554 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5555 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5556 when fetching a multibyte character consumes more bytes than
5557 CHAR_BYTES returns, due to unification of CJK characters in
5558 string_char. (Bug#11073)
5560 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5562 * process.c (wait_reading_process_output): Handle pty disconnect
5563 by refraining from sending oneself a SIGCHLD (bug#10933).
5565 2012-03-22 Chong Yidong <cyd@gnu.org>
5567 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5569 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5570 Mark string as coming from a prefix property.
5571 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5572 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5574 2012-03-21 Chong Yidong <cyd@gnu.org>
5576 * xfaces.c (Vface_remapping_alist): Doc fix.
5578 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5580 * w32proc.c (Fw32_set_console_codepage)
5581 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5584 2012-03-20 Chong Yidong <cyd@gnu.org>
5586 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5587 to reflect default non-nil value of redisplay-dont-pause.
5589 2012-03-19 Kenichi Handa <handa@m17n.org>
5591 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5592 it fit in a valid range (Bug#11003).
5594 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5596 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5597 that is not from display property, accept the row as a "cursor
5598 row" if one of the string's character has a non-nil `cursor'
5599 property. Fixes cursor positioning when there are newlines in
5600 overlay strings, e.g. in icomplete.el. (Bug#11035)
5602 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5604 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5606 2012-03-12 Chong Yidong <cyd@gnu.org>
5608 * eval.c (inhibit_lisp_code): Rename from
5609 inhibit_window_configuration_change_hook; move from window.c.
5611 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5612 * window.c (run_window_configuration_change_hook)
5613 (syms_of_window): Callers changed.
5615 2012-03-11 Chong Yidong <cyd@gnu.org>
5617 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5619 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5621 2012-03-10 Chong Yidong <cyd@gnu.org>
5623 * frame.c (other_visible_frames): Don't assume the selected frame
5624 is visible (Bug#10955).
5626 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5628 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5630 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5632 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5633 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5636 2012-03-03 Glenn Morris <rgm@gnu.org>
5638 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5640 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5642 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5643 position past the first glyph_row that ends at ZV. (Bug#10902)
5644 (redisplay_window, next_element_from_string): Fix typos in
5646 (redisplay_window): Pass to move_it_vertically the margin in
5647 pixels, not in screen lines.
5649 2012-03-02 Glenn Morris <rgm@gnu.org>
5651 * buffer.c (buffer-list-update-hook): Doc fix.
5653 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5655 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5656 push_it before setting up the iterator for the first overlay
5657 string, even if we have an empty string loaded.
5658 (next_overlay_string): If there's an empty string on the iterator
5659 stack, pop the stack. (Bug#10903)
5661 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5663 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5664 Suggested by Stefan Monnier in
5665 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5666 * alloc.c (widen_to_Lisp_Object): New static function.
5667 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5668 and widening them to Lisp_Objects. This would work even if
5669 USE_LSB_TAG is defined and wide integers are used, which might
5670 happen in a future version of Emacs.
5672 2012-02-25 Chong Yidong <cyd@gnu.org>
5674 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5677 * xselect.c (Fx_selection_exists_p): Doc fix.
5678 (x_clipboard_manager_save_all): Print an informative message
5679 before saving to clipboard manager.
5681 2012-02-24 Chong Yidong <cyd@gnu.org>
5683 * keyboard.c (process_special_events): Handle all X selection
5684 requests in kbd_buffer, not just the next one (Bug#8869).
5686 2012-02-23 Chong Yidong <cyd@gnu.org>
5688 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5689 call when setting menu-bar-lines and tool-bar-lines parameters.
5690 (unwind_create_frame_1): New helper function.
5692 * window.c (inhibit_window_configuration_change_hook): New var.
5693 (run_window_configuration_change_hook): Obey it.
5694 (syms_of_window): Initialize it.
5696 2012-02-22 Chong Yidong <cyd@gnu.org>
5698 * xterm.c (x_draw_image_relief): Add missing type check for
5699 Vtool_bar_button_margin (Bug#10743).
5701 2012-02-21 Chong Yidong <cyd@gnu.org>
5703 * fileio.c (Vfile_name_handler_alist): Doc fix.
5705 * buffer.c (Fget_file_buffer): Protect against invalid file
5706 handler return value.
5708 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5710 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5711 when computing $valmask.
5713 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5714 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5715 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5716 It's useless in that case, and it can cause problems on hosts
5717 that allocate halves of EMACS_INT values separately.
5718 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5719 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5720 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5721 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5722 it avoids undefined behavior on hosts where shifting right by more
5723 than the word width has undefined behavior.
5725 2012-02-19 Chong Yidong <cyd@gnu.org>
5727 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5728 (Funhandled_file_name_directory, Ffile_name_as_directory)
5729 (Fdirectory_file_name, Fexpand_file_name)
5730 (Fsubstitute_in_file_name): Protect against invalid file handler
5731 return values (Bug#10845).
5733 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5735 * .gdbinit (pitx): Fix incorrect references to fields of the
5738 2012-02-17 Chong Yidong <cyd@gnu.org>
5740 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5742 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5744 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5745 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5747 2012-02-15 Chong Yidong <cyd@gnu.org>
5749 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5750 marked as special. Also, starting docstrings with * is obsolete.
5752 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5754 * gnutls.c (emacs_gnutls_write): Fix last change.
5756 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

5761 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5763 * keymap.c (Fsingle_key_description): Handle char ranges.
5765 2012-02-12 Chong Yidong <cyd@gnu.org>
5767 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5768 as that creates a dangerous corner case.
5770 * window.c (Fdelete_window_internal): Invalidate the mouse
5771 highlight (Bug#9904).
5773 2012-02-12 Glenn Morris <rgm@gnu.org>
5775 * xselect.c (Fx_own_selection_internal)
5776 (Fx_get_selection_internal, Fx_disown_selection_internal)
5777 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5778 * nsselect.m (Fx_own_selection_internal)
5779 (Fx_disown_selection_internal, Fx_selection_exists_p)
5780 (Fx_selection_owner_p, Fx_get_selection_internal):
5781 Sync docs and argument specs with the xselect.c versions.
5783 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5785 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5787 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5789 * w32select.c (Fx_selection_exists_p): Sync doc string and
5790 argument list with xselect.c. (Bug#10783)
5792 * w16select.c (Fx_selection_exists_p): Sync doc string and
5793 argument list with xselect.c. (Bug#10783)
5795 2012-02-10 Glenn Morris <rgm@gnu.org>

6322 (Fword_search_backward_lax, Fword_search_forward_lax):
6323 Use `Fword_search_regexp' instead of `wordify'. Doc fix.
6324 (syms_of_search): Define `Sword_search_regexp'. (Bug#10145)
6326 2011-12-01 Stefan Monnier <monnier@iro.umontreal.ca>
6328 * fileio.c (Finsert_file_contents): Move after-change-function call
6329 to before the "handled:" label, since all "goto handled" appear in
6330 cases where the *-change-functions have already been properly called

6375 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
6376 of scroll runs so as to avoid assigning disabled bogus rows and
6377 unnecessary graphics copy operations.
6379 2011-11-27 Eli Zaretskii <eliz@gnu.org>
6381 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

6388 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6389 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
6390 this macro definition.
6392 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
6395 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

6417 * xdisp.c (redisplay_window): If cursor row is not fully visible
6418 after recentering, and scroll-conservatively is set to a large
6419 number, scroll window by a few more lines to make the cursor fully
6420 visible and out of scroll-margin. (Bug#10105)
6421 (start_display): Don't move to the next line if the display should
6422 start at a newline that is part of a display vector or an overlay

6503 Otherwise, valgrind does not work on some platforms.
6504 Problem reported by Andreas Schwab in
6505 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6506 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6507 is set, removing the need for VIRT_ADDRESS_VARIES.
6508 (PURE_P): Use a more-efficient implementation that needs just one
6509 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6510 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6511 to 4 (xorl, subq, cmpq, setbe).
6512 * alloc.c (pure): Always extern now, since that's the
6513 VIRT_ADDR_VARIES behavior.
6514 (PURE_POINTER_P): Use a single comparison, not two, for
6515 consistency with the new puresize.h.
6516 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6517 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6523 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6524 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6525 behave as if the cursor position were at the window margin.
6527 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6528 and the cursor position is out of bounds, behave as if the cursor
6529 position were at the window margin. (Bug#10075)
6531 2011-11-18 Chong Yidong <cyd@gnu.org>
6533 * window.c (Fwindow_combination_limit): Make first argument
6534 non-optional, since it is meaningless for live windows like the

6555 compute_line_metrics.
6556 (compute_line_metrics): Call row_hash, instead of computing the
6559 * dispnew.c (verify_row_hash): Call row_hash for computing the
6560 hash code of a row, instead of duplicating code from xdisp.c.
6562 * dispextern.h (row_hash): Add prototype.
6564 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6566 * frame.c (delete_frame): Don't delete the terminal when the last
6567 X frame is closed if emacs is built with GTK toolkit.

6589 (Fset_window_nest): Rename to Fset_window_combination_limit.
6590 (Vwindow_nest): Rename to Vwindow_combination_limit.
6591 (recombine_windows, make_parent_window, make_window)
6592 (Fsplit_window_internal, saved_window)
6593 (Fset_window_configuration, save_window_save): Rename all
6594 occurrences of window_nest to window_combination_limit.
6596 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6598 * image.c (imagemagick_load_image): Fix typo.
6600 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6602 * xdisp.c (display_line): Move the call to
6603 highlight_trailing_whitespace before the call to
6604 compute_line_metrics, since the latter needs to see the final
6605 faces of all the glyphs to compute ROW's hash value.
6606 Fixes assertion violations in row_equal_p. (Bug#10035)
6608 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6610 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6615 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6616 with user-defined heap size. Bump the default size of the temacs
6617 heap to 27MB, to avoid memory warning when running temacs.
6618 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6620 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6667 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6669 Avoid some portability problems by eschewing 'extern inline' functions.
6670 The trivial performance wins aren't worth the portability hassles; see
6671 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6673 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6674 (window_box_width, window_box_left, window_box_left_offset)
6675 (window_box_right, window_box_right_offset): Undo previous change,
6676 by removing the "extern"s.
6677 * intervals.c (adjust_intervals_for_insertion)
6678 (adjust_intervals_for_deletion): Undo previous change,
6679 making these static again.
6680 (offset_intervals, temp_set_point_both, temp_set_point)
6681 (copy_intervals_to_string): No longer inline.
6682 * xdisp.c (window_text_bottom_y, window_box_width)

6719 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
6721 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6722 This is also needed for porting to any host where GC_MARK_STACK is
6723 not GC_MAKE_GCPROS_NOOPS.
6724 (which_symbols): Use it.
6726 2011-11-07 Kenichi Handa <handa@m17n.org>

6739 * xmenu.c (cleanup_widget_value_tree): New function.
6740 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6747 (window_box_width, window_box_left, window_box_left_offset)
6748 (window_box_right, window_box_right_offset): Declare extern.
6749 Otherwise, these inline functions do not conform to C99 and
6750 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6751 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6752 * intervals.c (adjust_intervals_for_insertion)
6753 (adjust_intervals_for_deletion): Now extern, because otherwise the
6754 extern inline functions 'offset_intervals' couldn't refer to it.
6755 (static_offset_intervals): Remove.
6756 (offset_intervals): Rewrite using the old contents of
6757 static_offset_intervals. The old version didn't conform to C99
6758 because an extern inline function contained a reference to an
6759 identifier with static linkage.
6761 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6763 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6781 (Fwindow_vscroll): Doc fix.
6782 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6783 argument, since it makes no sense to pass a live window and for
6784 consistency with window-child.

6994 (w32font_open_internal, compute_metrics):
6995 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6996 instead of calling the "wide" APIs directly.
6998 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

7048 * keyboard.c (test_undefined): New function (bug#9751).
7049 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7051 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7053 * sysdep.c (init_sys_modes): Fix the check for the controlling
7054 terminal (Bug#6649).
7056 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7058 * dispextern.h (struct bidi_it): New member next_en_type.
7060 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7061 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7062 current character, check also for next_en_type being WEAK_EN.
7063 (bidi_resolve_weak): Don't enter the expensive loop if the current
7064 position is before next_en_pos. Record the bidi type of the first
7065 non-ET, non-BN character we find, in addition to its position.
7066 (bidi_level_of_next_char): Invalidate next_en_type when
7067 next_en_pos is over-stepped.
7069 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7071 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7072 * editfns.c: Rewrite current-time-zone so that it invokes
7073 the equivalent of (format-time-string "%Z") to get the time zone name.
7074 This fixes a bug when the time zone name contains characters that
7075 need converting from the system time locale to Emacs internal format.
7076 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7077 that patch fixed format-time-string to do the conversion, but
7078 I forgot to fix current-time-zone.
7079 (format_time_string): New function, containing most of
7080 what Fformat_time_string used to contain.
7081 (Fformat_time_string): Rewrite in terms of format_time_string.
7082 This doesn't change this function's behavior.
7083 (current-time-zone): Rewrite to use format_time_string.
7084 This fixes the bug reported by Michael Schierl in
7085 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7086 Jason Rumney's 2007-06-07 change worked around this bug, but
7088 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7090 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7092 * xdisp.c (start_display): If the character at POS is displayed
7093 via a display vector, reset IT->current.dpvec_index to zero.
7094 (try_window_reusing_current_matrix): If a line ends in a display
7095 vector or the next line starts in a display vector, continue
7096 redrawing the window even though the character position of
7097 start_row was reached.
7100 2011-10-18 Chong Yidong <cyd@gnu.org>
7102 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7103 with nobreak-char-display too.
7105 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7107 Fix part 3 of bug#9771.
7108 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7109 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7110 non-neutral characters if the current character is a paragraph
7111 separator (a.k.a. Newline). This avoids running the same
7112 expensive loop twice, once when we consume the preceding newline
7113 and the other time when the line actually needs to be displayed.
7114 Avoid the loop when we see neutrals on the base embedding level
7115 following a character whose directionality is the same as the
7116 paragraph's. This avoids running the expensive loop when a line
7117 ends in a long sequence of neutrals, like control characters.
7118 Add assertion against STRONG_AL type. Slightly rearrange code
7119 that determines the type of a neutral given the first non-neutral
7121 (bidi_level_of_next_char): Set next_en_pos to zero when
7122 invalidating its info.
7124 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7126 * xdisp.c (push_display_prop): Determine whether to record string
7127 or buffer position by IT->string, not by IT->method. Allow
7128 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7129 (move_it_vertically_backward): Don't look for character position
7130 immediately after the newline when in a continuation line.
7133 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7135 * window.c (coordinates_in_window): Rewrite and delabelize
7136 vertical border check. (Bug#5357) (Bug#9618)
7138 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7140 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7141 errors in XSetWindowBorder (bug#9310).
7143 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7145 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7146 avoid crash when xmalloc overrun checking is enabled.
7148 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7150 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7151 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7152 cursor motion with <left> and <right> arrow keys.
7154 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7155 some callers set that themselves.
7157 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7159 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7160 display string and the previous row comes from the same string and
7161 is empty. (Bug#9739) (Bug#9738)
7163 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7165 * doc.c (get_doc_string): Encode file name (bug#9735).
7167 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7169 * bidi.c (bidi_level_of_next_char):
7170 * xdisp.c (get_visually_first_element): Remove old incorrect
7171 comments regarding the Unicode Line Separator character.
7173 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7175 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7177 * alloc.c (Fgc_status): Do not access beyond zombies array
7178 boundary if nzombies > MAX_ZOMBIES.
7179 * alloc.c (dump_zombies): Add missing format specifier.
7181 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7183 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7184 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7186 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7187 Some packages use them to denote characters with modifiers.
7189 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7191 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7192 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7193 matching a pp-number. Rename parameter var to var1.
7195 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7197 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7199 2011-10-08 Glenn Morris <rgm@gnu.org>
7201 * callint.c (Fcall_interactively): Give a more explicit error for the
7202 'c' case with a non-character input. (Bug#8479)
7204 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7206 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7208 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7209 lines that are hscrolled on the left.
7211 * dispnew.c (buffer_posn_from_coords): Account for a possible
7212 presence of header-line. (Bug#4426)
7214 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>

7217 Don't advertise functionality which we discourage or doesn't work.
7219 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7221 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7222 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7223 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7224 this makes Emacs dump core during garbage collection on rare
7225 occasions. sizeof is obviously inferior to offsetof here, so
7226 stick with offsetof.
7227 (GC_POINTER_ALIGNMENT): New macro.
7228 (mark_memory): Omit 3rd (offset) arg; caller changed.
7229 Don't assume EMACS_INT alignment is the same as pointer alignment.
7231 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7233 * keyboard.c (read_key_sequence_remapped): New var.
7234 (read_key_sequence): Compute remapping in the right buffer.
7235 (command_loop_1): Use read_key_sequence's remapping directly.
7237 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7239 * dired.c (file_name_completion): Don't expand file name.
7240 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7241 before checking file name handler.
7243 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7244 they've been requested explicitly (bug#9591).
7246 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7248 * keymap.c (Fsingle_key_description): Use make_specified_string
7249 instead of build_string to build string from push_key_description.
7252 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7254 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7255 This fixes a Y2038 bug on 64-bit hosts.
7256 * buffer.c (reset_buffer):
7257 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7258 (Fclear_buffer_auto_save_failure):
7259 Use 0, not -1, to represent an unset failure time, since time_t
7260 might not be signed.
7262 Remove dependency on glibc malloc internals.
7263 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7264 Move back here from lisp.h, but with their new implementations.
7265 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7266 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7267 * charset.c (charset_table_init): New static var.
7268 (syms_of_charset): Use it instead of xmalloc. This removes a
7269 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7270 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7271 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7272 Move back to alloc.c.
7273 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7274 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7276 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7278 * nsterm.m (windowDidResize): Call x_set_window_size only when
7279 ns_in_resize is true. Otherwise set pixelwidth/height and
7280 call change_frame_size (Bug#9628).
7282 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7284 Port --enable-checking=all to Fedora 14 x86-64.
7285 * charset.c (syms_of_charset): Also account for glibc malloc's
7286 internal overhead when calculating the initial malloc maximum.
7288 Port --enable-checking=all to Fedora 14 x86.
7289 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7291 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7292 (overrun_check_realloc, overrun_check_free):
7293 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7294 That way, xmalloc returns a properly-aligned pointer even if
7295 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7296 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7297 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7298 into account when calculating the initial malloc maximum.
7299 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7300 Move here from alloc.c, so that charset.c can use it too.
7301 Properly align; the old code wasn't right for common 32-bit hosts
7302 when configured with --enable-checking=all.
7303 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7304 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7306 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7308 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7311 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7313 * xdisp.c (compute_display_string_end): If there's no display
7314 string at CHARPOS, return -1.
7316 * bidi.c (bidi_fetch_char): When compute_display_string_end
7317 returns a negative value, treat the character as a normal
7318 character not covered by a display string. (Bug#9624)
7320 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7322 * lread.c (Fread_from_string): Fix typo in docstring.
7324 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7326 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7327 newline, reseat the iterator instead of bidi-iterating there one
7328 character at a time. (Bug#9610)
7329 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7330 TO_CHARPOS if the bidi iterator is at base embedding level.
7332 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7334 * lread.c (readevalloop): Use correct code for NBSP.
7335 (read1): Likewise. (Bug#9608)
7337 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7339 * dbusbind.c (Fdbus_register_signal): When service is not
7340 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7342 2011-09-25 Glenn Morris <rgm@gnu.org>
7344 * buffer.c (truncate-lines): Doc fix.
7346 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7348 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7349 (Fset_window_next_buffers): Doc fix.
7351 2011-09-24 Glenn Morris <rgm@gnu.org>
7353 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7355 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7357 Fix minor problems found by static checking.
7358 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7359 * indent.c (Fvertical_motion): Fix == vs = typo.
7361 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7363 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7364 Default value is now t. Doc fix.
7366 * indent.c (Fvertical_motion): Compute and apply the overshoot
7367 logic when moving up, not only when moving down. Fix the
7368 confusing name and values of the it_overshoot_expected variable;
7369 logic changes accordingly. (Bug#9254) (Bug#9549)
7371 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7372 CHARPOS is covered by a display string which includes newlines.
7373 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7374 is covered by a display string with embedded newlines.
7376 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7378 * dbusbind.c (Fdbus_register_signal): Add match rule to
7379 Vdbus_registered_objects_table. (Bug#9581)
7380 (Fdbus_register_method, Vdbus_registered_objects_table):
7383 2011-09-24 Jim Meyering <meyering@redhat.com>
7385 do not ignore write error for any output size
7386 The previous change was incomplete.
7387 While it makes emacs --batch detect the vast majority of stdout
7388 write failures, errors were still ignored whenever the output size is
7389 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7390 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7391 && echo FAIL: ignored write error
7392 FAIL: ignored write error
7393 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7394 && echo FAIL: ignored write error
7395 FAIL: ignored write error
7396 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7398 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7400 * emacs.c (Fkill_emacs): In noninteractive mode exit
7401 non-successfully if a write error occurred on stdout. (Bug#9574)
7403 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7405 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7408 * dispextern.h (struct it): Update the comment documenting what
7411 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7413 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7414 a display string, extend search for cursor position to end of row.
7415 (find_row_edges): If the row ends in a newline from a display
7416 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7417 Handle the case of a display string with multiple newlines.
7418 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7419 non-empty line. Fixes confusing cursor motion with arrow keys at
7420 the beginning of a line that starts with whitespace.
7422 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7424 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7427 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7429 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7432 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7434 * xdisp.c (display_line): Record maximum and minimum buffer
7435 positions even if no glyphs were produced (e.g., by a zero-width
7436 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7437 buffer positions that will be removed from the glyph row because
7439 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7440 column is beyond frame width: don't subtract 1 "pixel" when
7441 computing width of the stretch.
7442 (reseat_at_next_visible_line_start): Undo the change made on
7443 2011-09-17 that saved paragraph information and restored it after
7444 the call to `reseat'. (Bug#9545)
7446 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7448 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7449 and turn window cursor on if cleared (Bug#9415).
7451 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7453 * search.c (boyer_moore): Take unibyte characters from pattern
7454 literally. (Bug#9458)
7456 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7458 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7460 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7462 Fix minor problem found by static checking.
7463 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7464 initialized, to pacify gcc -Wuninitialized.
7466 * fileio.c: Report proper errno when syscall falls.
7467 (Finsert_file_contents): Save and restore errno,
7468 so that report_file_error outputs the correct diagnostic.
7469 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7471 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7473 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7475 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7477 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7478 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7480 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7482 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7483 about the current paragraph and restore it after the call to reseat.
7485 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7486 (bidi_find_paragraph_start): Search back for paragraph beginning
7487 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7488 (bidi_move_to_visually_next): Only trigger paragraph-related
7489 computations when the last character is a newline or at EOB, not
7490 just any NEUTRAL_B. (Bug#9470)
7492 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7493 truncated lines if point is covered by a display string. (Bug#9524)
7495 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7497 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7498 (cons_to_x_long): New function.
7499 (lisp_data_to_selection_data): Use it. Correct the test for
7500 short-versus-long data; it was negated. Break out of vector
7501 loop, for efficiency, when a long datum is discovered.
7503 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7505 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7507 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7509 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7510 GCC PR/17406) by declaring this function with external scope.
7512 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7514 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7515 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7517 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7519 * editfns.c (Fformat): Correctly handle text properties on "%%".

7526 * composite.c (composition_update_it, get_composition_id):
7527 * xdisp.c (get_next_display_element)
7528 (fill_composite_glyph_string): Add comments about special meaning
7529 of TAB characters in a composition.
7531 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7533 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7534 This occurs when processing a multibyte format.
7535 Problem reported by Wolfgang Jenker.
7537 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7539 * xdisp.c (try_cursor_movement): Only check for exact match if
7540 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7542 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7544 Remove unused external symbols.
7545 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7546 * xdisp.c (calc_pixel_width_or_height): Now static.
7547 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7548 * indent.c (check_display_width):
7549 * w32term.c: Fix comment to match code.
7550 * xterm.c, xterm.h (x_catching_errors): Remove.
7552 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7554 * xselect.c: Use signed conversions more consistently (Bug#9498).
7555 (selection_data_to_lisp_data): Assume incoming selection data are
7556 signed integers, not unsigned. This is to be consistent with
7557 outgoing selection data, which was modified to use signed integers
7558 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7559 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7560 expects long, not unsigned long.
7562 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7564 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7565 computation of loop end. Reported by Johan Bockgård
7568 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7570 * frame.c (Fother_visible_frames_p): Function deleted.
7572 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7574 * indent.c (compute_motion): Process display vector front to back
7575 rather than the other way around. (Bug#2496)
7577 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7579 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7581 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7583 * minibuf.c (Fread_from_minibuffer): Doc fix.
7585 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7587 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7588 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7590 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7592 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7593 value for non-existent files.
7595 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7597 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7598 set its "size" to -1. This will set the modtime_size field of
7599 the corresponding buffer to -1, which is what
7600 verify-visited-file-modtime expects for files that do not exist.
7603 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7605 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7607 * lisp.h: ... from here. push_key_description is no longer
7608 defined in keyboard.c, so its declaration should not be in
7609 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7610 logically belongs with push_key_description.
7612 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7614 * buffer.h: Include <sys/types.h> instead of <time.h>.
7615 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7616 Problem reported by Herbert J. Skuhra.
7618 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7620 * xml.c (parse_region): Make the parsing work for
7621 non-comment-starting XML files again (bug#9144).
7623 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7625 * image.c (gif_load): Fix calculation of bottom and right corner.
7628 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7630 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7631 redisplay in small windows.
7633 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7635 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7637 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7639 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7640 Operate on live windows only.
7642 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7644 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7646 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7648 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7649 only under bidi iteration.
7651 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7653 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7655 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7657 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7658 Without this fix, the command to link temacs failed due to an
7659 undefined symbol __builtin_isnan. This is because
7660 /usr/include/iso/math_c99.h #defines isnan(x) to
7661 __builtin_isnan(x), but the bundled gcc, which identifies itself
7662 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7664 * floatfns.c (isnan): #undef, and then #define to a clone of
7666 (Fisnan): Always define, since it's always available now.
7667 (syms_of_floatfns): Always define isnan at the Lisp level.
7669 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7671 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7673 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7675 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7676 The previous code assumed that file offsets (off_t values) fit in
7677 EMACS_INT variables, which is not true on typical 32-bit hosts.
7678 The code messed up by falsely reporting buffer overflow in cases
7679 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7680 when "big" contains more than 2**29 bytes, even though this
7681 inserts just one byte and does not overflow the buffer.
7682 (Finsert_file_contents): Store file offsets as off_t
7683 values, not as EMACS_INT values. Check for overflow when
7684 converting between EMACS_INT and off_t. When checking for
7685 buffer overflow or for overlap, take the offsets into account.
7686 Don't use EMACS_INT for small values where int suffices.
7687 When checking for overlap, fix a typo: ZV was used where
7688 ZV_BYTE was intended.
7689 (Fwrite_region): Don't assume off_t fits into 'long'.
7690 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7692 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7694 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7696 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7698 sprintf-related integer and memory overflow issues (Bug#9412).
7700 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7701 (esprintf, exprintf, evxprintf): New functions.
7702 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7703 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7704 (modify_event_symbol): Do not assume that the length of
7705 name_alist_or_stem is safe to alloca and fits in int.
7706 (Fexecute_extended_command): Likewise for function name and binding.
7707 (Frecursion_depth): Wrap around reliably on integer overflow.
7708 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7709 since some callers pass EMACS_INT values.
7710 (Fsingle_key_description): Don't crash if symbol name contains more
7711 than MAX_ALLOCA bytes.
7712 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7713 (get_minibuffer): Arg is now EMACS_INT, not int.
7714 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7715 (esprintf, exprintf, evxprintf): New decls.
7716 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7718 * dbusbind.c (signature_cat): New function.
7719 (xd_signature, Fdbus_register_signal):
7720 Do not overrun buffer; instead, report string overflow.
7722 * dispnew.c (add_window_display_history): Don't overrun buffer.
7723 Truncate instead; this is OK since it's just a log.
7725 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7726 even if the time zone offset is outlandishly large.
7727 Don't mishandle offset == INT_MIN.
7729 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7730 when creating daemon; the previous buffer-overflow check was incorrect.
7732 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7733 which has the guts of the old verror function.
7735 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7736 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7738 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7739 (font_unparse_xlfd): Don't blindly alloca long strings.
7740 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7741 fits in int, when using sprintf. Use single snprintf to count
7742 length of string rather than counting it via multiple sprintfs;
7743 that's simpler and more reliable.
7744 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7745 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7746 sprintf, in case result does not fit in int.
7748 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7749 (fontset_from_font): Print it.
7751 * frame.c (tty_frame_count): Now printmax_t, not int.
7752 (make_terminal_frame, set_term_frame_name): Print it.
7753 (x_report_frame_params): In X, window IDs are unsigned long,
7754 not signed long, so print them as unsigned.
7755 (validate_x_resource_name): Check for implausibly long names,
7756 and don't assume name length fits in 'int'.
7757 (x_get_resource_string): Don't blindly alloca invocation name;
7758 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7761 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7762 (xg_check_special_colors, xg_set_geometry):
7763 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7765 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7766 Use esprintf, not sprintf, in case result does not fit in int.
7768 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7769 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7770 it as a large positive number.
7771 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7772 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7774 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7775 in case result does not fit in int.
7777 * print.c (float_to_string): Detect width overflow more reliably.
7778 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7779 buffer overrun. Don't assume list length fits in 'int'. Treat
7780 print length of 0 as 0, not as infinity; to be consistent with other
7781 uses of print length in this function. Don't overflow print length
7782 index. Don't assume hash table size fits in 'long', or that
7783 vectorlike size fits in 'unsigned long'.
7785 * process.c (make_process): Use printmax_t, not int, to format
7786 process-name gensyms.
7788 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7790 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7791 to avoid potential buffer overrun.
7793 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7794 if X resource line is longer than 512 bytes.
7796 * xfns.c (x_window): Make sprintf buffer a bit bigger
7797 to avoid potential buffer overrun.
7799 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7801 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7803 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7805 Integer overflow fixes for scrolling, etc.
7806 Without these, Emacs silently mishandles large integers sometimes.
7807 For example, "C-u 4294967297 M-x recenter" was treated as if
7808 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7810 * xdisp.c (try_window_id): Check Emacs fixnum range before
7811 converting to 'int'.
7813 * window.c (window_scroll_line_based, Frecenter):
7814 Check that an Emacs fixnum is in range before assigning it to 'int'.
7815 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7816 values converted from Emacs fixnums.
7817 (Frecenter): Don't wrap around a line count if it is out of 'int'
7818 range; instead, treat it as an extreme value.
7819 (Fset_window_configuration, compare_window_configurations):
7820 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7822 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7823 that can exceed INT_MAX. Check that EMACS_INT value is in range
7824 before assigning it to the (possibly-narrower) index.
7825 (match_limit): Don't assume that a fixnum can fit in 'int'.
7827 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7830 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7831 (Fvertical_motion): Don't wrap around LINES values that don't fit
7832 in 'int'. Instead, treat them as extreme values. This is good
7833 enough for windows, which can't have more than INT_MAX lines anyway.
7835 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7837 * Require libxml/parser.h to avoid compilation warning.
7839 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7841 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7842 since this reportedly can destroy thread storage.
7844 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7846 * syntax.c (find_defun_start): Update all cache variables if
7847 exiting early (Bug#9401).
7849 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7851 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7853 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7854 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7855 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7857 * term.c (tty_append_glyph): New function.
7858 (produce_stretch_glyph): Static function and its prototype deleted.
7860 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7863 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7865 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7866 when checking :margin (Bug#9390).
7867 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7868 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7869 so that the name doesn't mislead. All uses changed.
7871 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7873 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7876 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7878 * xdisp.c (move_it_to): Don't bail out early when reaching
7879 position beyond to_charpos, if we are scanning backwards.
7880 (move_it_vertically_backward): When DY == 0, make sure we get to
7881 the first character in the line after the newline.
7883 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7885 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7886 (ccl_driver): Do not generate an out-of-range pointer.
7887 (Fccl_execute_on_string): Remove unnecessary check for
7888 integer overflow, noted by Stefan Monnier in
7889 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7890 Remove a FIXME that didn't need fixing.
7891 Simplify the newly-introduced buffer reallocation code.
7893 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7895 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7897 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7899 Integer and memory overflow issues (Bug#9196).
7901 * doc.c (get_doc_string): Rework so that
7902 get_doc_string_buffer_size is the actual buffer size, rather than
7903 being 1 less than the actual buffer size; this makes xpalloc more
7906 * image.c (x_allocate_bitmap_record, cache_image):
7907 * xselect.c (Fx_register_dnd_atom):
7908 Simplify previous changes by using xpalloc.
7910 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7911 since either will do and ptrdiff_t is convenient with xpalloc.
7913 * charset.c (charset_table_size)
7914 (struct charset_sort_data.priority): Now ptrdiff_t.
7915 (charset_compare): Don't overflow if priorities differ greatly.
7916 (Fsort_charsets): Don't assume list length fits in int.
7917 Check for size-calculation overflow when allocating sort data.
7918 (syms_of_charset): Allocate an initial charset table that is
7919 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7921 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7923 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7924 The actual value is always <= INT_MAX, and leaving it unsigned made
7925 overflow checking harder.
7927 * dispextern.h (struct glyph_matrix.rows_allocated)
7928 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7929 with xpalloc. The values are still always <= INT_MAX.
7931 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7933 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7934 (SAFE_NALLOCA): New macro.
7936 * region-cache.c (struct boundary.pos, find_cache_boundary)
7937 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7938 (set_cache_region, invalidate_region_cache)
7939 (revalidate_region_cache, know_region_cache, region_cache_forward)
7940 (region_cache_backward, pp_cache):
7941 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7942 so that ptrdiff_t * can be passed to xpalloc.
7943 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7944 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7945 (pp_cache): Don't assume cache_len fits in int.
7946 * region-cache.h: Adjust extern decls to match.
7948 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7949 EMACS_INT, since either will do, for xpalloc.
7951 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7952 (xnmalloc, xnrealloc, xpalloc): New functions.
7954 * bidi.c (bidi_shelve_header_size): New constant.
7955 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7956 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7958 * bidi.c (bidi_cache_shrink):
7959 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7961 Don't update size of array until after memory allocation succeeds,
7962 because xmalloc/xrealloc may not return.
7963 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7964 now that we have proper integer overflow checking.
7965 (record_overlay_string, overlay_strings): Catch overflows when
7966 calculating size of overlay_str_buf.
7968 * callproc.c (Fcall_process): Check for size overflow when
7969 calculating size of args2.
7970 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7971 Normally we prefer signed values, but sticking with ptrdiff_t would
7972 require adding more-complicated checks.
7974 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7975 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7976 Redo buffer-overflow calculations to avoid integer overflow.
7977 Add a FIXME comment where memory seems to be over-allocated.
7979 * character.c (Fstring): Check for size-calculation overflow.
7981 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7982 unnecessary integer overflow. Check for size overflow.
7983 (encode_coding_object): Don't update size until xmalloc succeeds.
7985 * composite.c (get_composition_id): Check for overflow in glyph
7986 length calculations.
7988 Integer and memory overflow fixes for display code.
7989 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7990 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7991 (scrolling_window): Check for overflow in size calculations.
7992 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7995 (row_table_size): Now ptrdiff_t, not int.
7996 (scrolling_window): Avoid overflow in size calculations.
7997 Don't update size until allocation succeeds.
7998 * fns.c (concat): Check for overflow in size calculations.
7999 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8000 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8001 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8003 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8004 (get_doc_string): Check for size calculation overflow.
8005 Don't update size until allocation succeeds.
8006 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8007 EMACS_INT, where ptrdiff_t will do.
8008 (Fsubstitute_command_keys): Check for string overflow.
8010 * editfns.c (set_time_zone_rule): Don't assume environment length
8012 (message_length): Now ptrdiff_t, not int.
8013 (Fmessage_box): Don't update size until allocation succeeds.
8014 Don't assume message length fits in int.
8015 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8017 * emacs.c (main): Do not reallocate argv, since there is a null at
8018 the end that can be overwritten, and this way there's no need to
8019 worry about size-calculation overflow.
8020 (sort_args): Check for size-calculation overflow.
8022 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8024 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8026 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8027 (x_set_scroll_bar_width, x_figure_window_size):
8028 Check for integer overflow.
8029 (x_set_alpha): Do not assume XINT fits in int.
8031 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8032 This is for the members text_lines, text_cols, total_lines, total_cols,
8033 where the system imposes an 'int' limit.
8035 * fringe.c (Fdefine_fringe_bitmap):
8036 Don't update size until alloc works.
8038 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8039 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8041 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8042 Check for size-calculation overflow.
8043 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8044 do, as we prefer signed integers.
8045 (id_to_widget.max_size, id_to_widget.used)
8046 (xg_store_widget_in_map, xg_remove_widget_from_map)
8047 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8048 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8049 Use and return ptrdiff_t, not int.
8050 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8051 * gtkutil.h: Change prototypes to match the above.
8053 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8054 are duplicate now that they've been promoted to lisp.h.
8055 (x_allocate_bitmap_record, x_alloc_image_color)
8056 (make_image_cache, cache_image, xpm_load):
8057 Don't update size until alloc is done.
8058 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8060 Check for size calculation overflow.
8061 (ct_colors_allocated_max): New constant.
8062 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
8065 * keyboard.c (read_char, menu_bar_items, tool_bar_items)

8067 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8068 Use ptrdiff_t, not int, to count maps.
8069 (read_char_minibuf_menu_prompt): Check for overflow in size
8070 calculations. Don't update size until allocation succeeds.
8071 Redo calculations to avoid overflow.

8081 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
8082 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8084 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8085 Now ptrdiff_t, not int.
8086 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8087 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
8089 * process.c (Fnetwork_interface_list): Check for overflow
8090 in size calculation.
8092 * region-cache.c (move_cache_gap): Check for size calculation overflow.
8094 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
8095 overflow. Don't bother calling xmalloc when xrealloc will do.
8097 * search.c (Freplace_match): Check for size calculation overflow.
8098 (Fset_match_data): Don't assume list lengths fit in 'int'.
8100 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8101 for command line length. Do not attempt to address one before the
8102 beginning of an array, as that's not portable.
8104 * term.c (max_frame_lines): Remove; unused.
8105 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8107 (encode_terminal_code, calculate_costs): Check for size
8108 calculation overflow.

8111 done. Redo calculations to avoid overflow.
8112 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8114 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
8115 subtracting pointers.

8120 Don't update size until alloc done.
8121 Redo size calculations to avoid overflow.

8130 Use ptrdiff_t, not int, for sizes.
8131 (Finternal_make_lisp_face, cache_face):
8132 Check for size calculation overflow.
8133 (cache_face): Treat size calculation overflows as if they were
8134 memory exhaustion (the usual treatment), rather than aborting.
8136 * xfns.c (x_encode_text, x_set_name_internal)
8137 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8138 sizes, since they can exceed INT_MAX in size. Check for size
8139 calculation overflow.
8141 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8142 (xg_select): Check for size calculation overflow.
8143 Don't update size until alloc done.
8145 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8146 as sprintf is limited to int lengths.
8148 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8149 (X_LONG_MIN): New macros.
8150 Use them to make the following changes clearer.
8151 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8152 This change doesn't affect the value now, but it may help remind
8153 future maintainers not to raise the value too much later.
8154 (SELECTION_QUANTUM): Remove, replacing with ...
8155 (selection_quantum): ... new function, which avoids overflow.
8157 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8158 assumption that selection length fits in 'int'.
8159 (x_reply_selection_request, x_handle_selection_request)
8160 (x_get_window_property, receive_incremental_selection)
8161 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8162 (lisp_data_to_selection_data, clean_local_selection_data):
8163 Use ptrdiff_t, not int, to record length of selection.
8164 (x_reply_selection_request, x_get_window_property)
8165 (receive_incremental_selection, x_property_data_to_lisp):
8166 Redo calculations to avoid overflow.
8167 (x_reply_selection_request): When sending hint, ceiling it at
8168 X_LONG_MAX rather than relying on wraparound overflow to send
8170 (x_get_window_property, receive_incremental_selection)
8171 (lisp_data_to_selection_data, x_property_data_to_lisp):
8172 Check for size-calculation overflow.
8173 (x_get_window_property, receive_incremental_selection)
8174 (lisp_data_to_selection_data, Fx_register_dnd_atom):
8175 Don't store size until memory allocation succeeds.
8176 (x_get_window_property): Plug memory leak on memory exhaustion.
8177 Don't double-block input; malloc is safe here. Don't assume 2**34
8178 - 4 fits in unsigned long. Add an xassert to check
8179 XGetWindowProperty overflow. Be more careful about overflow
8180 calculations, and distinguish size from memory overflow better.
8181 (receive_incremental_selection): When tracing, don't assume
8182 unsigned int is less than INT_MAX.
8183 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8184 harmful) conversions of unsigned short to int.
8185 (lisp_data_to_selection_data): Don't assume that integers
8186 in the range -65535 through -1 fit in an X unsigned short.
8187 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8188 result parameters unless successful. Rely on cons_to_unsigned
8189 to report problems with elements; the old code wasn't right anyway.
8190 (x_check_property_data): Check for int overflow; we cannot use
8191 a wider type due to X limits.
8192 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8194 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8196 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8197 (x_term_init): Check for size calculation overflow.
8198 (x_color_cells): Don't store size until memory allocation succeeds.

8223 * image.c (xpm_get_color_table_h):
8224 * lisp.h (hash_lookup, hash_put):
8225 * minibuf.c (Ftest_completion):
8226 Use ptrdiff_t for hash table indexes, not int (which is too
8227 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8228 32-bit --with-wide-int hosts).
8230 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8231 Add a FIXME comment about memory leaks.
8232 (syms_of_charset): Don't assume xmalloc returns.
8234 Don't assume that stated character widths fit in int.
8235 * character.c (Fchar_width, c_string_width, lisp_string_width):
8236 * character.h (CHAR_WIDTH):
8237 * indent.c (MULTIBYTE_BYTES_WIDTH):
8238 Use sanitize_char_width to avoid undefined and/or bad behavior
8239 with outlandish widths.
8240 * character.h (sanitize_tab_width): Rename from sanitize_width,
8241 now that we have two such functions. All uses changed.
8242 (sanitize_char_width): New inline function.
8244 Don't assume that tab-width fits in int.
8245 * character.h (sanitize_width): New inline function.
8246 (SANE_TAB_WIDTH): New macro.
8247 (ASCII_CHAR_WIDTH): Use it.
8248 * indent.c (sane_tab_width): Remove. All uses replaced by

8260 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8261 (x_send_scroll_bar_event): Likewise. Check that the size does not
8262 exceed limits imposed by XClientMessageEvent, as well as the usual
8263 ptrdiff_t and size_t limits.
8265 * keyboard.c: Overflow, signedness and related fixes.
8266 (make_lispy_movement): Use same integer type in forward decl
8267 that is used in the definition.
8268 (read_key_sequence, keyremap_step):
8269 Change bufsize argument back to int, undoing my 2011-03-30 change.
8270 We prefer signed types, and int is wide enough here.
8271 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8272 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8273 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8274 length, not size_t. Use ptrdiff_t for index, not int.
8275 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8276 possibility of integer overflow.
8278 Overflow, signedness and related fixes for images.

8288 * xdisp.c (calc_pixel_width_or_height):
8289 * xfns.c (image_cache_refcount):
8290 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8291 on typical 64-bit hosts.
8293 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8294 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8299 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8300 (lookup_image): Remove unnecessary tests.
8301 (xbm_image_p): Locals are now of int, not EMACS_INT,
8302 since parse_image_check makes sure they fit into int.
8303 (png_load, gif_load, svg_load_image):
8304 Prefer int to unsigned where either will do.
8305 (tiff_handler): New function, combining the cores of the
8306 old tiff_error_handler and tiff_warning_handler.
8307 This function is rewritten to use vsnprintf and thereby avoid
8308 stack buffer overflows. It uses only the features of vsnprintf
8309 that are common to both POSIX and native Microsoft.
8310 (tiff_error_handler, tiff_warning_handler): Use it.
8311 (tiff_load, gif_load, imagemagick_load_image):
8312 Don't assume :index value fits in 'int'.
8313 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8314 (imagemagick_load_image): Check that crop parameters fit into
8315 the integer types that MagickCropImage accepts. Don't assume
8316 Vimagemagick_render_type has a nonnegative value. Don't assume
8317 size_t fits in 'long'.
8318 (gs_load): Use printmax_t to print the widest integers possible.

8326 2011-08-25 Eli Zaretskii <eliz@gnu.org>
8328 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8329 the display spec is of the form `(space ...)'.
8330 (handle_display_spec): Return the value returned by
8331 handle_single_display_spec, not just 1 or zero.
8332 (handle_single_display_spec): If the display spec is of the form
8333 `(space ...)', and specifies display in the text area, return 2
8335 (try_cursor_movement): Check for the need to scroll more
8336 accurately, and prefer exact match for point under bidi.
8337 Don't advance `row' beyond the last row of the window.
8339 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8340 into disp_prop; all users changed.
8342 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8343 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8344 for the text covered by the display property.
8346 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8348 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8355 buffers, return left-to-right.
8356 (set_cursor_from_row): Consider candidate row a win if its glyph
8357 represents a newline and point is on that newline. Fixes cursor
8358 positioning on the newline at EOL of R2L text within L2R
8359 paragraph, and vice versa.
8360 (try_cursor_movement): Check continued rows, in addition to
8361 continuation rows. Fixes unwarranted scroll when point enters a
8362 continued line of R2L text within an L2R paragraph, or vice versa.
8363 (cursor_row_p): Consider the case of point being equal to
8364 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8365 from the end of a short line to the beginning of a continued line
8366 of R2L text within L2R paragraph.
8367 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8368 composed characters.
8370 * bidi.c (bidi_check_type): Use xassert.

8379 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8381 * nsfont.m (ns_otf_to_script): Fix typo.
8383 2011-08-22 Kenichi Handa <handa@m17n.org>
8385 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8386 extra slot even if the purpose is char-code-property-table.
8388 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8390 * xdisp.c (redisplay_window): When computing centering_position,
8391 account for the height of the header line. (Bug#8874)
8393 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8394 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8395 candidate is selected by the mouse, and that candidate has a
8396 composed character under the mouse.
8398 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8399 coordinates reported by pos-visible-in-window-p for a composed
8400 character in column zero.
8402 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8404 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8406 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8408 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8409 consider it a hit if to_charpos is anywhere in the range of the
8410 composed buffer positions.
8412 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8414 * image.c (gif_load): Don't assume that each subimage has the same
8415 dimensions as the base image. Handle disposal method that is
8416 "undefined" by the gif spec (Bug#9335).
8418 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8420 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8421 (Fcondition_case): Document `debug' symbol in error handler.
8423 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8425 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8426 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8427 from an Org mode buffer to a Speedbar frame.
8429 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8430 a composition, take its buffer position from IT->cmp_it.charpos.
8431 Fixes cursor positioning at the beginning of a line that begins
8432 with a composed character.
8434 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8436 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8437 character bidirectional type, use STRONG_L instead. Fixes crashes
8438 in a buffer produced by `describe-categories'.
8440 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8441 members before the level stack, so they would be saved and
8442 restored when copying iterator state. Fixes incorrect reordering
8443 around TABs covered by display properties.
8445 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8447 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8455 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8457 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8458 has no `load' handler, try opening the file locally. (Bug#9311)
8460 2011-08-16 Ken Brown <kbrown@cornell.edu>

8480 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8482 [CYGWIN] (special_realloc): New function.
8483 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8484 requests to realloc storage in the static heap.

8517 * xdisp.c (move_it_in_display_line_to): Don't invoke
8518 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8519 ppos_it. Fixes vertical cursor motion when line beginning is
8520 covered by an image. (Bug#9296)
8522 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8524 * nsterm.h (ns_run_ascript): Declare.

8527 * nsfns.m (as_script, as_result, as_status): New static variables.
8528 (ns_run_ascript): New function.
8529 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8530 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8531 the event loop. Get status from as_status (Bug#7276).
8533 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8534 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8535 the event loop (Bug#7276).
8537 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8539 * gnutls.c (QCgnutls_bootprop_priority)

8560 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8561 (Fnetwork_interface_list): Allocate in increments of bytes instead
8562 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8563 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8565 (struct ifflag_def): notrailers is smart on OSX.
8566 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8567 Get hardware address with getifaddrs if available.
8569 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8571 * xdisp.c (iterate_out_of_display_property): xassert that
8572 IT->position is set to within IT->object's boundaries. Break from
8573 the loop as soon as EOB is reached; avoids infloops in redisplay
8574 when IT->position is set up wrongly due to some bug.
8575 Set IT->current to match the bidi iterator unconditionally.
8576 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8577 entry. Force push_it to save on the stack the current
8578 buffer/string position, to be restored by pop_it. Fix flags in
8579 the iterator structure wrt the object coming from a display
8580 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8581 properties. (Bug#9284)
8583 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8585 * fontset.c (fontset_get_font_group): Add proper type checks.

8591 and LC_VERSION_MIN_MACOSX.
8592 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8593 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8595 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8597 * xdisp.c (forward_to_next_line_start): Allow to use the
8598 no-display-properties-and-no-overlays under bidi display.
8599 Set disp_pos in the bidi iterator to avoid searches for display
8600 properties and overlays.
8602 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8604 * editfns.c (Fset_time_zone_rule): Document relationship with the
8607 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8608 the font entity extracted from the cache (Bug#8109).
8610 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8612 * composite.c (autocmp_chars): Don't reset point. That is done by
8613 restore_point_unwind (Bug#5984).
8615 2011-08-07 Juri Linkov <juri@jurta.org>
8617 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8618 to show the arg `TIME' instead of `TIMEVAL'.
8620 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8622 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8623 display property strides EOL and includes a newline, as in
8624 longlines-mode. (Bug#9254)
8625 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8626 word-wrap under bidirectional display. (Bug#9224)
8628 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8629 is non-zero, even if the data buffer is NULL. Fixes a crash in
8630 vertical-motion with longlines-mode. (Bug#9254)
8632 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8634 * bidi.c <bidi_cache_total_alloc>: Now static.
8635 (bidi_initialize): Initialize bidi_cache_total_alloc.
8637 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8640 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8641 amount allocated this far in `bidi_cache_total_alloc'.
8642 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8643 non-zero, only free the data buffer without restoring the cache
8644 contents. All callers changed.
8646 * dispextern.h (bidi_unshelve_cache): Update prototype.
8648 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8649 (move_it_in_display_line, move_it_to)
8650 (move_it_vertically_backward, move_it_by_lines): Replace the call
8651 to xfree to an equivalent call to bidi_unshelve_cache.
8652 (move_it_in_display_line_to): Fix logic of returning
8653 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8655 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8657 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8658 came from a string character with a `cursor' property. (Bug#9229)
8660 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8662 * Makefile.in (LIB_PTHREAD): New variable.
8663 (LIBES): Add LIB_PTHREAD (Bug#9216).
8665 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8666 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8668 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8670 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8672 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8674 * xterm.c (x_find_topmost_parent): New function.
8675 (x_set_frame_alpha): Find topmost parent window with
8676 x_find_topmost_parent and set the property there also (bug#9181).
8677 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8679 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8681 * callproc.c (Fcall_process): Avoid vfork clobbering
8682 the local vars buffer, coding_systems, current_dir.
8684 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8686 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8688 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8690 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8691 so that it is not optimized away.
8693 * xdisp.c (compute_display_string_pos): Remove unused local.
8695 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8697 Fix slow cursor motion and scrolling in large buffers with
8698 selective display, like Org Mode buffers. (Bug#9218)
8700 * dispextern.h (struct bidi_it): New member disp_prop_p.
8702 * xdisp.c: Remove one-slot cache of display string positions.
8703 (compute_display_string_pos): Accept an additional argument
8704 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8705 for a display string or property. If found, set DISP_PROP_P
8708 * bidi.c (bidi_fetch_char): Accept an additional argument
8709 DISP_PROP_P, and pass it to compute_display_string_pos.
8710 Only handle text covered by a display string if DISP_PROP_P is returned
8711 non-zero. All callers of bidi_fetch_char changed.
8713 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8715 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8717 2010-12-03 Don March <don@ohspite.net>
8719 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8720 last character M-[char] is translated to ESC [char] (bug#7541).
8722 2011-08-02 Kenichi Handa <handa@m17n.org>
8724 * lisp.h (uniprop_table): Extern it.
8726 * chartab.c (uniprop_table): Make it non-static.
8728 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8730 * xdisp.c (forward_to_next_line_start): Accept additional argument
8731 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8733 (reseat_at_next_visible_line_start): Use the bidi iterator state
8734 returned by forward_to_next_line_start to restore the state of
8735 it->bidi_it after backing up to previous newline. (Bug#9212)
8737 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8739 * regex.c (re_comp): Protoize.
8740 (re_exec): Fix return type.
8741 (regexec): Fix type of `ret'. (Bug#9203)
8743 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8745 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8746 This is needed if max-image-size is a floating-point number.
8748 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8750 * print.c (print_object): Print empty symbol as ##.
8752 * lread.c (read1): Read ## as empty symbol.
8754 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8756 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8757 setting frame foreground color (Bug#9175).
8758 (x_set_background_color): Likewise.
8760 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8761 contents (Bug#9176).
8762 (EmacsTooltip -init): Remove bezels and add shadows to
8765 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8766 or scroll bar (Bug#8470).
8768 * nsfont.m (nsfont_open): Remove assignment to voffset and
8769 unnecessary vars hshink, expand, hd, full_height, min_height.
8770 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8772 * nsterm.h (nsfont_info): Remove voffset field.
8774 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8776 Implement strike-through and overline on NextStep (Bug#8863).
8778 * nsfont.m (nsfont_open): Use underline position provided by font,
8779 instead of hard-coded value of 2.
8780 (nsfont_draw): Call ns_draw_text_decoration instead.
8782 * nsterm.h: Add declaration for ns_draw_text_decoration.
8784 * nsterm.m (ns_draw_text_decoration): New function for drawing
8785 underline, overline, and strike-through.
8786 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8787 ns_draw_text_decoration. Change treatment of cursor drawing to
8788 accommodate underlining, etc.
8790 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8792 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8795 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8797 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8798 Without this fix, if a signal arrives just after memory fills up,
8799 'malloc' might be invoked reentrantly.
8801 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8802 In other words, assume that every image size is allowed, on non-X
8803 hosts. This assumption is probably wrong, but it lets Emacs compile.
8805 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8807 * regex.c (re_iswctype): Convert return values to boolean.
8809 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8811 * xdisp.c (compute_display_string_pos): Don't use cached display
8812 string position if the buffer had its restriction changed.
8815 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8817 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8819 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8821 Integer signedness and overflow and related fixes. (Bug#9079)
8823 * bidi.c: Integer size and overflow fixes.
8824 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8825 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8826 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8827 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8828 (bidi_find_other_level_edge):
8829 Use ptrdiff_t instead of EMACS_INT where either will do.
8830 This works better on 32-bit hosts configured --with-wide-int.
8831 (bidi_cache_ensure_space): Check for size-calculation overflow.
8832 Use % rather than repeated addition, for better worst-case speed.
8833 Don't set bidi_cache_size until after xrealloc returns, because it
8835 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8836 (bidi_cache_ensure_space): Also check that the bidi cache size
8837 does not exceed that of the largest Lisp string or buffer. See Eli
8838 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8840 * alloc.c (__malloc_size_t): Remove.
8841 All uses replaced by size_t. See Andreas Schwab's note
8842 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8844 * image.c: Improve checking for integer overflow.
8845 (check_image_size): Assume that f is nonnull, since
8846 it is always nonnull in practice. This is one less thing to
8847 worry about when checking for integer overflow later.
8848 (x_check_image_size): New function, which checks for integer
8849 overflow issues inside X.
8850 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8851 This removes the need for a memory_full check.
8852 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8853 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8854 (xbm_read_bitmap_data): Change locals back to 'int', since
8855 their values must fit in 'int'.
8856 (xpm_load_image, png_load, tiff_load):
8857 Invoke x_create_x_image_and_pixmap earlier,
8858 to avoid much needless work if the image is too large.
8859 (tiff_load): Treat overly large images as if
8860 x_create_x_image_and_pixmap failed, not as malloc failures.
8861 (gs_load): Use x_check_image_size.
8863 * gtkutil.c: Omit integer casts.
8864 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8865 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8867 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8869 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8870 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8871 would wrongly return t on a 64-bit host.
8873 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8874 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8875 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8876 and therefore cause GCC to emit a bogus diagnostic in some cases.
8878 * image.c: Integer signedness and overflow and related fixes.
8879 This is not an exhaustive set of fixes, but it's time to
8880 record what I've got.
8881 (lookup_pixel_color, check_image_size): Remove redundant decls.
8882 (check_image_size): Don't assume that arbitrary EMACS_INT values
8883 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8884 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8885 (tiff_load, imagemagick_load_image):
8886 Check for overflow in size calculations.
8887 (x_create_x_image_and_pixmap): Remove unnecessary test for
8888 xmalloc returning NULL; that can't happen.
8889 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8890 (xpm_color_bucket): Use better integer hashing function.
8891 (xpm_cache_color): Don't possibly over-allocate memory.
8892 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8893 (gif_memory_source):
8894 Use ptrdiff_t, not int or size_t, to record sizes.
8895 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8896 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8897 either works, as we prefer signed integers.
8898 (tiff_read_from_memory, tiff_write_from_memory):
8899 Return tsize_t, not size_t, since that's what the TIFF API wants.
8900 (tiff_read_from_memory): Don't fail simply because the read would
8901 go past EOF; instead, return a short read.
8902 (tiff_load): Omit no-longer-needed casts.
8903 (Fimagemagick_types): Don't assume size fits into 'int'.
8905 Improve hashing quality when configured --with-wide-int.
8906 * fns.c (hash_string): New function, taken from sxhash_string.
8907 Do not discard information about ASCII character case; this
8908 discarding is no longer needed.
8909 (sxhash-string): Use it. Change sig to match it. Caller changed.
8910 * lisp.h: Declare it.
8911 * lread.c (hash_string): Remove, since we now use fns.c's version.
8912 The fns.c version returns a wider integer if --with-wide-int is
8913 specified, so this should help the quality of the hashing a bit.
8915 * emacs.c: Integer overflow minor fix.
8916 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8917 Define only if GNU_LINUX.
8918 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8920 * dispnew.c: Integer signedness and overflow fixes.
8921 Remove unnecessary forward decls, that were a maintenance hassle.
8922 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8924 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8925 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8926 (prepare_desired_row, line_draw_cost):
8927 Use int, not unsigned, where either works.
8928 (save_current_matrix, restore_current_matrix):
8929 Use ptrdiff_t, not size_t, where either works.
8930 (init_display): Check for overflow more accurately, and without
8931 relying on undefined behavior.
8933 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8934 Remove, replacing with the new symbols in lisp.h. All uses changed.
8935 * fileio.c (make_temp_name):
8936 * filelock.c (lock_file_1, lock_file):
8937 * xdisp.c (message_dolog):
8938 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8939 Use pMd etc. instead.
8940 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8941 replacing the pWIDE etc. symbols removed from editfns.c.
8943 * keyboard.h (num_input_events): Now uintmax_t.
8944 This is (very slightly) less likely to mess up due to wraparound.
8947 * buffer.c: Integer signedness fixes.
8948 (alloc_buffer_text, enlarge_buffer_text):
8949 Use ptrdiff_t rather than size_t when either will do, as we prefer
8952 * alloc.c: Integer signedness and overflow fixes.
8953 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8954 (__malloc_size_t): Default to size_t, not to int.
8955 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8956 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8957 Prefer ptrdiff_t to size_t when either would do, as we prefer
8959 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8960 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8961 Now const. Initialize with values that are in range even if char
8963 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8964 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8965 These functions do the right thing with sizes > 2**32.
8966 (check_depth): Now ptrdiff_t, not int.
8967 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8968 Adjust to new way of storing sizes. Check for size overflow bugs
8970 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8971 slightly wrong anyway, as it missed one instance of
8972 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8973 (refill_memory_reserve): Omit needless cast to size_t.
8974 (mark_object_loop_halt): Mark as externally visible.
8976 * xselect.c: Integer signedness and overflow fixes.
8977 (Fx_register_dnd_atom, x_handle_dnd_message):
8978 Use ptrdiff_t, not size_t, since we prefer signed.
8979 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8980 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8981 x_dnd_atoms_size and x_dnd_atoms_length.
8983 * doprnt.c: Prefer signed to unsigned when either works.
8985 * doprnt.c (doprnt):
8987 * xdisp.c (vmessage):
8988 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8989 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8990 prefer signed arithmetic to avoid comparison confusion.
8991 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8992 but is a bit tricky.
8994 Assume freestanding C89 headers, string.h, stdlib.h.
8995 * data.c, doprnt.c, floatfns.c, print.c:
8996 Include float.h unconditionally.
8997 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8998 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8999 * regex.c: Likewise for stddef.h, string.h.
9000 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9001 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9002 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9003 (STDC_HEADERS): Remove obsolete defines.
9004 * sysdep.c: Include limits.h unconditionally.
9006 Assume support for memcmp, memcpy, memmove, memset.
9007 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9008 * regex.c (memcmp, memcpy):
9009 Remove; we assume C89 now.
9011 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9012 (__malloc_safe_bcopy): Remove; no longer needed.
9014 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9015 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9016 well either way, and we prefer signed to unsigned.
9018 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9020 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9021 closes the connection while we're reading (bug#9182).
9023 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9025 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9026 are specified (Bug#9168).
9028 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9030 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9031 Found by GCC static checking and --with-wide-int on a 32-bit host.
9033 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9035 * xdisp.c (compute_display_string_pos): Fix logic of caching
9036 previous display string position. Initialize cached_prev_pos to
9037 -1. Fixes slow-down at the beginning of a buffer.
9039 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9041 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9042 for attrs[LFACE_FONTSET_INDEX].
9044 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9046 * xml.c (parse_region): Remove unused local
9047 that was recently introduced.
9049 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9051 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9052 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9054 * xdisp.c (move_it_in_display_line_to): Record the best matching
9055 position for TO_CHARPOS while scanning the line, and restore it on
9056 exit if none of the characters scanned was an exact match.
9057 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9058 when exact match is impossible due to invisible text, and the
9059 lines are truncated.
9061 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9063 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9066 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9068 Fix a significant slow-down of cursor motion with C-n, C-p,
9069 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9070 auto-repeat under bidi redisplay in fontified buffers.
9071 * xdisp.c (compute_stop_pos_backwards): New function.
9072 (next_element_from_buffer): Call compute_stop_pos_backwards to
9073 find a suitable prev_stop when we find ourselves before
9075 (reseat): Don't look for prev_stop, as that could mean a very long
9077 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9078 <cached_disp_overlay_modiff>: Cache for last found display string
9080 (compute_display_string_pos): Return the cached position if asked
9081 about the same buffer in the same area of character positions, and
9082 the buffer wasn't changed since the time the display string
9083 position was cached.
9085 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9087 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9088 is an integer, which is important for empty lines. (Bug#9149)
9090 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9092 * frame.c (Fmodify_frame_parameters): In tty case, update the
9093 default face if necessary (Bug#4238).
9095 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9097 * editfns.c (Fstring_to_char): No need to explain what a character
9098 is in the docstring (Bug#6576).
9100 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9102 * xml.c (parse_region): Make sure we always return a tree.
9104 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9106 * xml.c (parse_region): If a document contains only comments,
9109 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9111 * xml.c (make_dom): Return comments, too.
9113 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9116 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9117 and the surrounding thread.
9118 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9119 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9120 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9122 * s/openbsd.h (BROKEN_SIGIO): Define.
9123 * unexelf.c (unexec) [__OpenBSD__]:
9124 Don't update the .mdebug section of the Alpha COFF symbol table.
9126 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9128 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9131 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>

9134 This fixes some race conditions on the permissions of any newly
9137 * alloc.c (valid_pointer_p): Use pipe, not open.
9138 This fixes some permissions issues when debugging.
9140 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9141 If fchown fails to set both uid and gid, try to set just gid,
9142 as that is sometimes allowed. Adjust the file's mode to eliminate
9143 setuid or setgid bits that are inappropriate if fchown fails.
9145 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9147 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9148 to compare Lisp_Objects.

9159 symbol character follows.
9161 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9163 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9164 This works around a problem with the previous change to Fcopy_file.
9165 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9166 and without this change, GCC might complain about discarding
9167 fchown's return value.
9169 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9171 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9173 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9175 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9177 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9179 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9180 it's used from the C level.
9182 * process.c: Use the same condition for POLL_FOR_INPUT in both
9183 keyboard.c and process.c (bug#1858).
9185 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9192 * doc.c (Fsubstitute_command_keys): Revert last change.
9194 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9196 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9197 quotes the next character, and doesn't affect other longer
9198 sequences (bug#8935).
9200 * lread.c (syms_of_lread): Clarify that is isn't only
9201 `eval-buffer' and `eval-defun' that's affected by
9202 `lexical-binding' (bug#8460).

9212 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9213 (elsz): Now a signed constant, not a size_t var. We prefer signed
9214 types to unsigned, to avoid integer comparison confusion. Without
9215 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9216 "cannot optimize loop, the loop counter may overflow", a symptom
9218 * indent.c (Fvertical_motion): Mark locals as initialized.
9219 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9221 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9223 * search.c (Fre_search_backward): Mention `case-fold-search' in
9224 all the re_search_* functions (bug#8138).
9226 * keyboard.c (Fopen_dribble_file): Document when the file is

9244 buffer position was specified. Initialize paragraph_embedding to
9246 (reseat_to_string): Initialize the bidi iterator.
9247 (display_string): If we need to ignore text properties of
9248 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

9259 Fix calculation of the object to scan. Fixes an error when using
9261 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9262 base_level_stop; instead, set base_level_stop to BEGV.
9263 Fixes crashes in vertical-motion.
9264 (next_element_from_buffer): Improve commentary for when
9265 the iterator is before prev_stop.
9266 (init_iterator): Initialize bidi_p from the default value of
9267 bidi-display-reordering, not from buffer-local value. Use the
9268 buffer-local value only if initializing for buffer iteration.
9269 (handle_invisible_prop): Support invisible properties on strings
9270 that are being bidi-reordered.
9271 (set_iterator_to_next): Support bidi reordering of C strings and

9289 parts of next_element_from_buffer, next_element_from_string, and
9290 next_element_from_c_string.

9307 pushed the iterator stack, restore the internal state of the bidi
9308 iterator by calling bidi_pop_it same number of times.
9309 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9310 and we are bidi-iterating, don't decrement the iterator position;

9784 Random fixes. E.g., (random) never returned negative values.
9785 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9786 subseconds part to the entropy, as that's a bit more random.
9787 Prefer signed to unsigned, since the signedness doesn't matter and
9788 in general we prefer signed. When given a limit, use a
9789 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9790 latter isn't right if USE_2_TAGS_FOR_INTS.
9791 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9792 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9805 This is more efficient than Ffile_directory_p and avoids a minor race.
9807 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9809 * buffer.c (Foverlay_put): Say what the return value is
9812 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9813 is a directory before asking whether to use the file name
9815 (barf_or_query_if_file_exists): Make the "File is a directory"
9816 error be more correct.
9818 * fns.c (Frequire): Remove the mention of the .gz files, since
9819 that's installation-specific, but keep the mention of
9820 `get-load-suffixes'.
9822 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9824 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9835 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9937 * eval.c (struct backtrace): Simplify and port the data structure.
9938 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9939 signed bit field, as this assumption is not portable and it makes
9940 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9941 "char debug_on_exit : 1" as this is not portable either; instead,
9942 use the portable "unsigned int debug_on_exit : 1". Remove unused
9943 member evalargs. Remove obsolete comments about cc bombing out.

10035 pending. Suggested by Jan Djärv (Bug#8869).
10037 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
10039 Use gnulib's dup2 module instead of rolling our own.
10040 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
10042 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10044 * dispnew.c (scrolling_window): Before scrolling, turn off a

10107 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10109 Integer and buffer overflow fixes (Bug#8873).
10111 * print.c (printchar, strout): Check for string overflow.
10112 (PRINTPREPARE, printchar, strout):
10113 Don't set size unless allocation succeeds.
10115 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10116 for sizes. Check for string overflow more accurately.
10117 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10119 * macros.c: Integer and buffer overflow fixes.
10120 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10121 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10122 Use ptrdiff_t, not int, for sizes.
10123 Don't increment bufsize until after realloc succeeds.
10124 Check for size-calculation overflow.
10125 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10127 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10129 * lread.c: Integer overflow fixes.
10130 (read_integer): Radix is now EMACS_INT, not int,
10131 to improve quality of diagnostics for out-of-range radices.
10132 Calculate buffer size correctly for out-of-range radices.
10133 (read1): Check for integer overflow in radices, and in
10134 read-circle numbers.
10135 (read_escape): Avoid int overflow.
10136 (Fload, openp, read_buffer_size, read1)
10137 (substitute_object_recurse, read_vector, read_list, map_obarray):
10138 Use ptrdiff_t, not int, for sizes.

10153 2011-06-22 Leo Liu <sdl.web@gmail.com>
10155 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10156 Move to minibuffer.el.
10158 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10160 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10161 The following patches are for when GLYPH_DEBUG && !XASSERT.
10162 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10163 * dispnew.c (flush_stdout):
10164 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10165 Mark as externally visible.
10166 * dispnew.c (check_window_matrix_pointers): Now static.
10167 * dispnew.c (window_to_frame_vpos):
10168 * xfns.c (unwind_create_frame):
10169 * xterm.c (x_check_font): Remove unused local.
10170 * scroll.c (CHECK_BOUNDS):
10171 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10172 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10173 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10174 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10175 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10177 (debug_method_add): Use va_list and vsprintf rather than relying
10178 on undefined behavior with wrong number of arguments.
10179 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10180 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10181 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10182 since we're not interested in debugging glyphs with old libraries.
10183 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10184 GCC 4.6.0's static checking.
10186 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10188 Integer overflow and signedness fixes (Bug#8873).

10204 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10205 (.bitmaps_last, struct x_output.icon_bitmap):
10206 Use ptrdiff_t, not int, for bitmap indexes.
10207 (x_allocate_bitmap_record): Check for size overflow.
10208 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10210 Use ptrdiff_t, not int, for overlay counts.
10211 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10212 * editfns.c (overlays_around, get_pos_property):
10213 * textprop.c (get_char_property_and_overlay):
10214 * xdisp.c (next_overlay_change, note_mouse_highlight):
10215 * xfaces.c (face_at_buffer_position):
10216 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10217 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10218 (Fnext_overlay_change, Fprevious_overlay_change)
10219 (mouse_face_overlay_overlaps, Foverlays_in):
10220 Use ptrdiff_t, not int, for sizes.
10221 (overlays_at, overlays_in): Check for size-calculation overflow.
10223 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10225 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10226 (x_session_initialize): Do not assume string length fits in int.
10228 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10229 This is unlikely, but can occur if DPI is outlandish.
10231 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10232 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10234 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10235 * xrdb.c (magic_file_p, search_magic_path):
10236 Omit last arg SUFFIX; it was always 0. All callers changed.
10237 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10239 * xfont.c (xfont_match): Avoid need for strlen.
10241 * xfns.c: Don't assume strlen fits in int.
10242 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10244 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10245 not unsigned long, as we prefer signed integers. All callers changed.
10246 Detect integer overflow in repeat count.
10247 (message_dolog): Don't assume print length fits in 39 bytes.
10248 (display_mode_element): Don't assume strlen fits in int.
10250 * termcap.c: Don't assume sizes fit in int and never overflow.
10251 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10252 (gobble_line): Check for size-calculation overflow.
10254 * minibuf.c (Fread_buffer):
10255 * lread.c (intern, intern_c_string):

10260 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10262 * font.c: Don't assume string length fits in int.
10263 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10264 Use ptrdiff_t, not int.
10265 (font_intern_prop): Don't assume string length fits in int.
10266 Don't assume integer property fits in fixnum.
10267 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10269 * filelock.c: Fix some buffer overrun and integer overflow issues.
10270 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10271 Reformulate so as not to need the command string.
10272 Invoke gzip -cd rather than gunzip, as it's more portable.
10273 (lock_info_type, lock_file_1, lock_file):
10274 Don't assume pid_t and time_t fit in unsigned long.
10275 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10276 (current_lock_owner): Prefer signed type for sizes.
10277 Use memcpy, not strncpy, where memcpy is what is really wanted.
10278 Don't assume (via atoi) that time_t and pid_t fit in int.
10279 Check for time_t and/or pid_t out of range, e.g., via a network share.
10280 Don't alloca where an auto var works fine.
10282 * fileio.c: Fix some integer overflow issues.
10283 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10284 Don't assume string length fits in int.
10285 (directory_file_name): Don't assume string length fits in long.
10286 (make_temp_name): Don't assume pid fits in int, or that its print
10287 length is less than 20.
10289 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10291 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10293 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10295 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10296 We prefer signed integers, even for size calculations.
10298 * emacs.c: Don't assume string length fits in 'int'.
10299 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10300 (main): Don't invoke strlen when not needed.
10302 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10303 (XD_DEBUG_MESSAGE): Don't waste a byte.
10305 * callproc.c (getenv_internal_1, getenv_internal)
10306 (Fgetenv_internal):
10307 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10309 * lread.c (invalid_syntax): Omit length argument.
10310 All uses changed. This doesn't fix a bug, but it simplifies the
10311 code away from its former Hollerith-constant appearance, and it's
10312 one less 'int' to worry about when looking at integer-overflow issues.
10313 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10315 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10316 This didn't break anything, but it didn't help either.
10317 It's confusing to put a bogus integer in a place where the actual
10318 value does not matter.
10319 (LIST_END_P): Remove unused macro and its bogus comment.
10320 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10322 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10323 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10325 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10326 We prefer signed types, and the value cannot exceed the EMACS_INT
10327 range anyway (because otherwise the length would not be representable).
10328 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10329 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10330 This avoids a GCC warning when WIDE_EMACS_INT.
10332 * indent.c (sane_tab_width): New function.
10333 (current_column, scan_for_column, Findent_to, position_indentation)
10334 (compute_motion): Use it. This is just for clarity.
10335 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10337 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

10340 * composite.c (composition_gstring_put_cache):
10341 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10343 * editfns.c, insdel.c:
10344 Omit unnecessary forward decls, to simplify future changes.
10346 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10348 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10350 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10351 Use much-faster test for byte-length change.
10352 Don't assume string byte-length fits in 'int'.
10353 Check that character arg fits in 'int'.
10354 (mapcar1): Declare byte as byte, for clarity.
10356 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10358 * fns.c (concat): Catch string overflow earlier.
10359 Do not rely on integer wraparound.
10361 * dispextern.h (struct it.overlay_strings_charpos)
10362 (struct it.selective): Now EMACS_INT, not int.
10363 * xdisp.c (forward_to_next_line_start)
10364 (back_to_previous_visible_line_start)
10365 (reseat_at_next_visible_line_start, next_element_from_buffer):
10366 Don't arbitrarily truncate the value of 'selective' to int.
10368 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10370 * composite.c: Don't truncate sizes to 'int'.
10371 (composition_gstring_p, composition_reseat_it)
10372 (composition_adjust_point): Use EMACS_INT, not int.
10373 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10374 not EMACS_UINT, for indexes.
10376 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10378 * buffer.c: Include <verify.h>.
10379 (struct sortvec.priority, struct sortstr.priority):
10380 Now EMACS_INT, not int.
10381 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10382 (struct sortstr.size, record_overlay_string)
10383 (struct sortstrlist.size, struct sortlist.used):
10384 Don't truncate size to int.
10385 (record_overlay_string): Check for size-calculation overflow.
10386 (init_buffer_once): Check at compile-time, not run-time.
10388 2011-06-22 Jim Meyering <meyering@redhat.com>
10390 Don't leak an XBM-image-sized buffer
10391 * image.c (xbm_load): Free the image buffer after using it.
10393 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10396 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10397 that Sun C diagnosed.
10398 * fns.c (secure_hash): Fix pointer signedness issue.
10399 * intervals.c (static_offset_intervals): New function.
10400 (offset_intervals): Use it.
10402 2011-06-21 Leo Liu <sdl.web@gmail.com>
10405 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10408 * fns.c (secure_hash): Rename from crypto_hash_function and change
10409 the first arg to accept symbols.
10410 (Fsecure_hash): New primitive.
10411 (syms_of_fns): New symbols.
10413 2011-06-20 Deniz Dogan <deniz@dogan.se>
10415 * process.c (Fset_process_buffer): Clarify return value in
10418 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10420 * dispnew.c (add_window_display_history): Use BVAR.
10422 * xdisp.c (debug_method_add): Use BVAR.
10423 (check_window_end, dump_glyph_matrix, dump_glyph)
10424 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10426 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10429 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10430 check till after the cache is created in init_frame_faces.
10432 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10434 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10436 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10438 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10439 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10440 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10442 Improve buffer-overflow checking (Bug#8873).
10443 * fileio.c (Finsert_file_contents):
10444 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10445 Remove the old (too-loose) buffer overflow checks.
10446 They weren't needed, since make_gap checks for buffer overflow.
10447 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10448 The old code merely checked for Emacs fixnum overflow, and relied
10449 on undefined (wraparound) behavior. The new code avoids undefined
10450 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10452 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10453 Tune. Don't use wider integers than needed. Don't use alloca.
10454 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10456 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10458 * insdel.c, lisp.h (buffer_overflow): New function.
10459 (insert_from_buffer_1, replace_range, replace_range_2):
10460 * insdel.c (make_gap_larger):
10461 * editfns.c (Finsert_char):
10462 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10464 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10466 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10468 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10470 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10471 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10473 * fileio.c: Don't assume EMACS_INT fits in off_t.
10474 (emacs_lseek): New static function.
10475 (Finsert_file_contents, Fwrite_region): Use it.
10476 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10478 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10480 * fns.c: Don't overflow int when computing a list length.
10481 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10482 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10483 truncation on 64-bit hosts. Check for QUIT every
10484 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10485 faster and is responsive enough.
10486 (Flength): Report an error instead of overflowing an integer.
10487 (Fsafe_length): Return a float if the value is not representable
10488 as a fixnum. This shouldn't happen except in contrived situations.
10489 (Fnthcdr, Fsort): Don't assume list length fits in int.
10490 (Fcopy_sequence): Don't assume vector length fits in int.
10492 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10493 (header_size, word_size): New constants.
10494 (allocate_vectorlike): Don't check size overflow here.
10495 (allocate_vector): Check it here instead, since this is the only
10496 caller of allocate_vectorlike that could cause overflow.
10497 Check that the new vector's length is representable as a fixnum.
10499 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10500 The previous code was bogus. For example, next_almost_prime (32)
10501 returned 39, which is undesirable as it is a multiple of 3; and
10502 next_almost_prime (24) returned 25, which is a multiple of 5 so
10503 why was the code bothering to check for multiples of 7?
10505 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10507 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10509 Variadic C functions now count arguments with ptrdiff_t.
10510 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10511 Back then I didn't know that the Emacs coding style prefers signed int.
10512 Also, in the meantime I found a few more instances where arguments
10513 were being counted with int, which may truncate counts on 64-bit
10514 machines, or EMACS_INT, which may be unnecessarily wide.
10515 * lisp.h (struct Lisp_Subr.function.aMANY)
10516 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10517 Arg counts are now ptrdiff_t, not size_t.
10518 All variadic functions and their callers changed accordingly.
10519 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10520 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10521 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10522 * callint.c (Fcall_interactively): Check arg count for overflow,
10523 to avoid potential buffer overrun. Use signed char, not 'int',
10524 for 'varies' array, so that we needn't bother to check its size
10525 calculation for overflow.
10526 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10527 * eval.c (apply_lambda):
10528 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10529 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10530 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10532 * callint.c (Fcall_interactively): Don't use index var as event count.
10534 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10535 * mem-limits.h (SIZE): Remove; no longer used.
10537 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10539 Remove unnecessary casts.
10540 * xterm.c (x_term_init):
10541 * xfns.c (x_set_border_pixel):
10542 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10543 These aren't needed now that we assume ANSI C.
10545 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10546 It's more likely to cause problems (due to unsigned overflow)
10549 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10551 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10553 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10555 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10557 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10559 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10561 GLYPH_CODE_FACE returns EMACS_INT, not int.
10562 * dispextern.h (merge_faces):
10563 * xfaces.c (merge_faces):
10564 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10565 Don't assume EMACS_INT fits in int.
10567 * character.h (CHAR_VALID_P): Remove unused parameter.
10568 * fontset.c, lisp.h, xdisp.c: All uses changed.
10570 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10572 * fns.c (concat): Minor tuning based on overflow analysis.
10573 This doesn't fix any bugs. Use int to hold character, instead
10574 of constantly refetching from Emacs object. Use XFASTINT, not
10575 XINT, for value known to be a character. Don't bother comparing
10576 a single byte to 0400, as it's always less.
10578 * floatfns.c (Fexpt):
10579 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10581 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10584 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10586 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10587 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10588 incorrectly succeed when S was a string, because 4294967386 was
10589 truncated before it was used.
10591 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10592 Otherwise, an out-of-range integer could cause undefined behavior
10595 * composite.c: Use int, not EMACS_INT, for characters.
10596 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10597 EMACS_INT, for values that are known to be in character range.
10598 This doesn't fix any bugs but is the usual style inside Emacs and
10599 may generate better code on 32-bit machines.
10601 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10602 This is for reasons similar to the recent CHAR_STRING fix.
10603 * charset.c (Fencode_char): Check that character arg is actually
10604 a character. Pass an int to ENCODE_CHAR.
10605 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10606 wider than 'int', as a compile-time check to prevent future regressions
10609 * character.c (char_string): Remove unnecessary casts.
10611 Make sure a 64-bit char is never passed to CHAR_STRING.
10612 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10613 by silently ignoring the top 32 bits, allowing some values
10614 that were far too large to be valid characters.
10615 * character.h: Include <verify.h>.
10616 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10617 arguments are no wider than unsigned, as a compile-time check
10618 to prevent future regressions in this area.
10620 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10621 (Fsubst_char_in_region):
10623 * xdisp.c (decode_mode_spec_coding):
10624 Adjust to CHAR_STRING's new requirement.
10625 * editfns.c (Finsert_char, Fsubst_char_in_region):
10626 * fns.c (concat): Check that character args are actually
10627 characters. Without this test, these functions did the wrong
10628 thing with wildly out-of-range values on 64-bit hosts.
10630 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10631 These casts should not be needed on 32-bit hosts, either.
10632 * keyboard.c (read_char):
10633 * lread.c (Fload): Remove casts to unsigned.
10635 * lisp.h (UNSIGNED_CMP): New macro.
10636 This fixes comparison bugs on 64-bit hosts.
10637 (ASCII_CHAR_P): Use it.
10638 * casefiddle.c (casify_object):
10639 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10640 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10641 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10642 * dispextern.h (FACE_FROM_ID):
10643 * keyboard.c (read_char): Use UNSIGNED_CMP.
10645 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10646 not to EMACS_INT, to avoid GCC warning.
10648 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10650 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10651 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10652 isn't needed on 32-bit machines.
10654 * buffer.c (Fgenerate_new_buffer_name):
10655 Use EMACS_INT for count, not int.
10656 (advance_to_char_boundary): Return EMACS_INT, not int.
10658 * data.c (Qcompiled_function): Now static.
10660 * window.c (window_body_lines): Now static.
10662 * image.c (gif_load): Rename local to avoid shadowing.
10664 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10665 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10666 * alloc.c (make_save_value): Integer argument is now of type
10667 ptrdiff_t, not int.
10668 (mark_object): Use ptrdiff_t, not int.
10669 * lisp.h (pD): New macro.
10670 * print.c (print_object): Use it.
10672 * alloc.c: Use EMACS_INT, not int, to count objects.
10673 (total_conses, total_markers, total_symbols, total_vector_size)
10674 (total_free_conses, total_free_markers, total_free_symbols)
10675 (total_free_floats, total_floats, total_free_intervals)
10676 (total_intervals, total_strings, total_free_strings):
10677 Now EMACS_INT, not int. All uses changed.
10678 (Fgarbage_collect): Compute overall total using a double, so that
10679 integer overflow is less likely to be a problem. Check for overflow
10680 when converting back to an integer.
10681 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10682 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10683 These were 'int' variables that could overflow on 64-bit hosts;
10684 they were never used, so remove them instead of repairing them.
10685 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10686 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10687 Previously, this ceilinged at INT_MAX, but that doesn't work on
10689 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10691 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10692 (allocate_vectorlike): Check for ptrdiff_t overflow.
10693 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10694 when a (possibly-narrower) signed value would do just as well.
10695 We prefer using signed arithmetic, to avoid comparison confusion.
10697 * alloc.c: Catch some string size overflows that we were missing.
10698 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10699 for convenience in STRING_BYTES_MAX.
10700 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10701 The definition here is exact; the one in lisp.h was approximate.
10702 (allocate_string_data): Check for string overflow. This catches
10703 some instances we weren't catching before. Also, it catches
10704 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10705 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10706 and ptrdiff_t and EMACS_INT are both 64 bits.
10708 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10709 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10710 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10712 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10714 * alloc.c (Fmake_string): Check for out-of-range init.
10716 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10718 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10720 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10722 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10723 xg_get_default_scrollbar_width.
10725 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10726 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10727 (style_changed_cb): Call update_theme_scrollbar_width and call
10728 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10729 all frames (Bug#8505).
10730 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10731 Call gtk_window_set_resizable if HAVE_GTK3.
10732 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10733 and height if HAVE_GTK3 (Bug#8505).
10734 (scroll_bar_width_for_theme): New variable.
10735 (update_theme_scrollbar_width): New function.
10736 (xg_get_default_scrollbar_width): Move code to
10737 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10738 (xg_initialize): Call update_theme_scrollbar_width.
10740 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10742 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10744 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10746 * frame.c (make_frame): Call other_buffer_safely instead of
10749 * window.c (temp_output_buffer_show): Call display_buffer with
10750 second argument Vtemp_buffer_show_specifiers and reset latter
10751 immediately after the call.
10752 (Vtemp_buffer_show_specifiers): New variable.
10753 (auto_window_vscroll_p, next_screen_context_lines)
10754 (Vscroll_preserve_screen_position): Remove leading asterisks from
10757 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10759 Fix minor problems found by GCC 4.6.0 static checking.
10760 * buffer.c (Qclone_number): Remove for now, as it's unused.
10761 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10762 (record_buffer): Remove unused local.
10763 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10764 (set_frame_buffer_list): Remove; unused.
10765 * frame.h (other_visible_frames): Remove decl.
10766 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10767 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10768 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10770 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10771 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10772 Define only if HAVE_GPM.
10773 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10774 (update_hints_inhibit): Remove; never set. All uses removed.
10775 * widgetprv.h (emacsFrameClassRec): Remove decl.
10776 * window.c (delete_deletable_window): Now returns void, since it
10777 wasn't returning anything.
10778 (compare_window_configurations): Remove unused locals.
10779 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10780 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10781 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10782 the same widths as pointers. This follows up on the 2011-05-06 patch.
10783 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10784 * xterm.h: Likewise.

10790 (LISP_H): Add lib/intprops.h.
10792 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10794 * image.c (gif_load): Add animation frame delay to the metadata.
10795 (syms_of_image): Use DEFSYM. New symbol `delay'.
10797 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10799 * window.c (delete_deletable_window): Re-add.
10800 (Fset_window_configuration): Rewrite to handle dead buffers and
10801 consequently deletable windows.
10802 (window_tree, Fwindow_tree): Remove. Supply functionality in
10804 (compare_window_configurations): Simplify code.
10806 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10808 * image.c (imagemagick_load_image): Fix type mismatch.
10809 (Fimagemagick_types): Likewise.
10811 * window.h (replace_buffer_in_windows): Declare.
10813 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10815 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10816 Qclone_number. Remove external declaration of Qdelete_window.
10817 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10819 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10820 Run Qbuffer_list_update_hook if allowed.
10821 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10822 buffer list implementation.
10823 (other_buffer_safely): New function.
10824 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10825 calls to replace_buffer_in_windows and
10826 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10828 (record_buffer): Inhibit quitting and rewrite using quittable
10829 functions. Run Qbuffer_list_update_hook if allowed.
10830 (Frecord_buffer, Funrecord_buffer): New functions.
10831 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10832 Move switch-to-buffer to window.el.
10833 (bury-buffer): Move to window.el.
10834 (Vbuffer_list_update_hook): New variable.
10836 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10839 * window.h (resize_frame_windows): Move up in code.
10840 (Fwindow_frame): Remove EXFUN.
10841 (replace_buffer_in_all_windows): Remove prototype.
10842 (replace_buffer_in_windows_safely): Add prototype.
10844 * window.c: Declare Qdelete_window static again. Move down
10845 declaration of select_count.
10846 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10847 (Fother_window): Move to window.el.
10848 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10849 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
10850 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
10852 (replace_buffer_in_windows): Implement by calling
10853 Qreplace_buffer_in_windows.
10854 (replace_buffer_in_all_windows): Remove with some functionality
10855 moved into replace_buffer_in_windows_safely.
10856 (replace_buffer_in_windows_safely): New function.
10857 (select_window_norecord, select_frame_norecord): Move in front
10858 of run_window_configuration_change_hook. Remove now obsolete
10860 (Fset_window_buffer): Rewrite doc-string.
10861 Call Qrecord_window_buffer.
10862 (keys_of_window): Move binding for other-window to window.el.
10864 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10866 * dispextern.h (struct image): Replace data member, whose int_val
10867 and ptr_val fields were not used by anything, with a single
10870 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
10871 (gif_clear_image, gif_load, imagemagick_load_image)

11350 * gnutls.c: Use Emacs's memory allocators.
11351 Without this change, the gnutls library would invoke malloc etc.
11352 directly, which causes problems on non-SYNC_INPUT hosts, and which
11353 runs afoul of improving memory_full behavior. (Bug#8761)
11354 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11355 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11356 xfree instead of the default malloc, realloc, free.
11357 (Fgnutls_boot): No need to check for memory allocation failure,
11358 since xmalloc does that for us.
11360 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11361 * category.c (hash_get_category_set):
11362 * ccl.c (ccl_driver):
11363 * charset.c (Fdefine_charset_internal):
11364 * charset.h (struct charset.hash_index):
11365 * composite.c (get_composition_id, gstring_lookup_cache)
11366 (composition_gstring_put_cache):
11367 * composite.h (struct composition.hash_index):
11368 * dispextern.h (struct image.hash):
11369 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11370 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

11373 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11374 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11375 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11376 * image.c (make_image, search_image_cache, lookup_image)
11377 (xpm_put_color_table_h):
11378 * lisp.h (struct Lisp_Hash_Table):
11379 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11380 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11381 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11382 * alloc.c (allocate_vectorlike):
11383 Check for overflow in vector size calculations.
11384 * ccl.c (ccl_driver):
11385 Check for overflow when converting EMACS_INT to int.
11386 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11387 need to be updated by these changes.
11388 * fns.c (make_hash_table, maybe_resize_hash_table):
11389 Check for integer overflow with large hash tables.
11390 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11391 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11392 (SXHASH_REDUCE): New macro.
11393 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11394 Use it instead of discarding useful hash info with large hash values.
11395 (sxhash_float): New function.
11396 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11397 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11398 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11399 Rewrite to use FIXNUM_BITS, as this simplifies things.
11400 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11401 Adjust signatures to match updated version of code.
11402 (consing_since_gc): Now EMACS_INT, since a single hash table can
11403 use more than INT_MAX bytes.
11405 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11407 Make it possible to build with GCC-4.6+ -O2 -flto.
11409 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11411 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11413 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11414 Call minibuffer-inactive-mode.
11416 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11418 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11419 Update dependencies.
11421 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11423 * data.c (init_data): Remove code for UTS, this system is not
11426 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11428 Don't force ./temacs to start in terminal mode.
11430 * frame.c (make_initial_frame): Initialize faces in all cases, not
11431 only when CANNOT_DUMP is defined.
11432 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11434 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11436 * dispnew.c (add_window_display_history): Use const for the string
11437 pointer. Remove declaration, not needed.
11439 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11441 Use 'inline', not 'INLINE'.
11442 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11443 * alloc.c, fontset.c (INLINE): Remove.
11444 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11445 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11446 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11447 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11448 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11450 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11452 Make it possible to run ./temacs.
11454 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11455 syms_of_callproc does the same thing. Remove test for
11456 "initialized", do it in the caller.
11457 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11459 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11461 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11462 (read_minibuf): Use get_minibuffer.
11463 (syms_of_minibuf): Use DEFSYM.
11464 (Qmetadata): New var.
11465 * data.c (Qbuffer): Don't make it static.
11466 (syms_of_data): Use DEFSYM.
11468 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11470 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11471 (CCL_CODE_MIN): New macro.
11473 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11475 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11477 * eval.c (Qdebug): Now static.
11478 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11479 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11480 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11482 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11484 * image.c: Various fixes to ImageMagick code comments.
11485 (Fimagemagick_types): Doc fix.
11487 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11489 Minor fixes prompted by GCC 4.6.0 warnings.
11491 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11493 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11494 (x_clipboard_manager_save_all): Move extern decl to ...
11495 * xterm.h: ... here, so that it can be checked for consistency.
11497 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11499 * xselect.c (x_clipboard_manager_save_frame)
11500 (x_clipboard_manager_save_all): New functions.
11501 (Fx_clipboard_manager_save): Lisp function deleted.
11503 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11504 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11506 * xterm.h: Update prototype.
11508 2011-05-28 William Xu <william.xwl@gmail.com>
11510 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11511 exiting (Bug#8239).
11513 2011-05-28 Jim Meyering <meyering@redhat.com>
11515 Avoid a sign-extension bug in crypto_hash_function.
11516 * fns.c (to_uchar): Define.
11517 (crypto_hash_function): Use it to convert some newly-signed
11518 variables to unsigned, to avoid sign-extension bugs. For example,
11519 without this change, (md5 "truc") would evaluate to
11520 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11521 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11522 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11524 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11526 Integer overflow fixes.
11528 * dbusbind.c: Serial number integer overflow fixes.
11529 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11530 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11531 to hold a serial number that is too large for a fixnum.
11532 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11533 Check for serial numbers out of range. Decode any serial number
11534 that was so large that it became a float. (Bug#8722)
11536 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11537 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11538 Use XFASTINT rather than XUINT when numbers are nonnegative.
11539 (xd_append_arg, Fdbus_method_return_internal):
11540 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11541 arguments, check that Lisp number is nonnegative, rather than
11542 silently wrapping negative numbers around. (Bug#8722)
11543 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11546 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11548 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11550 ccl: Add integer overflow checks.
11551 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11552 (IN_INT_RANGE): New macros.
11553 (ccl_driver): Use them to check for integer overflow when
11554 decoding a CCL program. Many of the new checks are whether XINT (x)
11555 fits in int; it doesn't always, on 64-bit hosts. The new version
11556 doesn't catch all possible integer overflows, but it's an
11557 improvement. (Bug#8719)
11559 * alloc.c (make_event_array): Use XINT, not XUINT.
11560 There's no need for unsigned here.
11562 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11563 This follows up to the 2011-05-06 change that substituted uintptr_t
11564 for EMACS_INT. This case wasn't caught back then.
11566 Rework Fformat to avoid integer overflow issues.
11567 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11568 now (part of C89). Include <verify.h>.
11569 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11570 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11571 (Fformat): Avoid the prepass trying to compute sizes; it was only
11572 approximate and thus did not catch overflow reliably. Instead, walk
11573 through the format just once, formatting and computing sizes as we go,
11574 checking for integer overflow at every step, and allocating a larger
11575 buffer as needed. Keep track separately whether the format is
11576 multibyte. Keep only the most-recently calculated precision, rather
11577 than them all. Record whether each argument has been converted to
11578 string. Use EMACS_INT, not int, for byte and char and arg counts.
11579 Support field widths and precisions larger than INT_MAX. Avoid
11580 sprintf's undefined behavior with conversion specifications such as %#d
11581 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11582 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11583 formatting out-of-range floating point numbers with int
11584 formats. (Bug#8668)
11586 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11588 * data.c: Avoid integer truncation in expressions involving floats.
11589 * data.c: Include <intprops.h>.
11590 (arith_driver): When there's an integer overflow in an expression
11591 involving floating point, convert the integers to floating point
11592 so that the resulting value does not suffer from catastrophic
11593 integer truncation. For example, on a 64-bit host (* 4
11594 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11595 Do not rely on undefined behavior after integer overflow.
11597 merge count_size_as_multibyte, parse_str_to_multibyte
11598 * character.c, character.h (count_size_as_multibyte):
11599 Rename from parse_str_to_multibyte; all uses changed.
11600 Check for integer overflow.
11601 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11602 since it's now a duplicate of the other. This is more of
11603 a character than a buffer op, so better that it's in character.c.
11604 * fns.c, print.c: Adjust to above changes.
11606 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11608 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11610 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11612 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11613 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11614 (x_clipboard_manager_save): Now static.
11615 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11617 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11618 (crypto_hash_function): Now static.
11619 Fix pointer signedness problems. Avoid unnecessary initializations.
11621 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11623 * termhooks.h (Vselection_alist): Make it terminal-local.
11625 * terminal.c (create_terminal): Initialize it.
11627 * xselect.c: Support for clipboard managers.
11628 (Vselection_alist): Move to termhooks.h as terminal-local var.
11629 (LOCAL_SELECTION): New macro.
11630 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11631 (symbol_to_x_atom): Remove gratuitous arg.
11632 (x_handle_selection_request, lisp_data_to_selection_data)
11633 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11634 (x_own_selection, x_get_local_selection, x_convert_selection):
11635 New arg, specifying work frame. Use terminal-local Vselection_alist.
11636 (some_frame_on_display): Delete unused function.
11637 (Fx_own_selection_internal, Fx_get_selection_internal)
11638 (Fx_disown_selection_internal, Fx_selection_owner_p)
11639 (Fx_selection_exists_p): New optional frame arg.
11640 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11641 (x_handle_selection_clear): Don't treat other terminals with the
11642 same keyboard specially. Use the terminal-local Vselection_alist.
11643 (x_clear_frame_selections): Use Frun_hook_with_args.
11645 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11647 * xterm.h: Add support for those atoms.
11649 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11651 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11652 (converted_selections, conversion_fail_tag): New global variables.
11653 (x_selection_request_lisp_error): Free the above.
11654 (x_get_local_selection): Remove unnecessary code.
11655 (x_reply_selection_request): Args changed; handle arbitrary array
11656 of converted selections stored in converted_selections.
11657 Separate the XChangeProperty and SelectionNotify steps.
11658 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11659 (x_convert_selection): New function.
11660 (x_handle_selection_event): Simplify.
11661 (x_get_foreign_selection): Don't ignore incoming requests while
11662 waiting for an answer; this will fail when we implement
11663 SAVE_TARGETS, and seems unnecessary anyway.
11664 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11665 (Vx_sent_selection_functions): Doc fix.
11667 2011-05-26 Leo Liu <sdl.web@gmail.com>
11669 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11671 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11673 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11675 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11676 for fringe update if it has periodic bitmap.
11677 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11678 and fringe_bitmap_periodic_p.
11680 * fringe.c (get_fringe_bitmap_data): New function.
11681 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11682 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11683 row. Mark glyph row for fringe update if periodicity changed.
11685 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11686 for fringe update unless it has periodic bitmap.
11688 2011-05-25 Kenichi Handa <handa@m17n.org>

11706 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11707 Remove macros that are defined and never used.
11708 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11710 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11712 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11713 (Fx_get_selection_internal): Minor cleanup.

11739 report_file_error introduced by the change from 2011-05-07.
11741 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11743 * systime.h (Time): Define only if emacs is defined.
11744 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11745 where the include path doesn't have X11/X.h by default. See
11746 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11748 2011-05-20 Kenichi Handa <handa@m17n.org>
11750 * composite.c (find_automatic_composition): Fix previous change.
11752 2011-05-20 Glenn Morris <rgm@gnu.org>

11763 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11764 (lisp): Set the order to that of loadup.el.
11765 (shortlisp): Make it a copy of $lisp.
11766 (SOME_MACHINE_LISP): Remove.
11767 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11768 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11770 2011-05-18 Kenichi Handa <handa@m17n.org>
11772 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11773 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11774 (find_automatic_composition): Mostly rewrite for efficiency.
11776 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11778 * makefile.w32-in: Update dependencies.
11780 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11782 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11783 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11785 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11787 Fix some integer overflow issues, such as string length overflow.
11789 * insdel.c (count_size_as_multibyte): Check for string overflow.
11791 * character.c (lisp_string_width): Check for string overflow.
11792 Use EMACS_INT, not int, for string indexes and lengths; in
11793 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11794 the resulting string length overflows an EMACS_INT; instead,
11795 report a string overflow if no precision given. When checking for
11796 precision exhaustion, use a check that cannot possibly have
11797 integer overflow. (Bug#8675)
11798 * character.h (lisp_string_width): Adjust to new signature.
11800 * alloc.c (string_overflow): New function.
11801 (Fmake_string): Use it. This doesn't change behavior, but saves
11802 a few bytes and will simplify future changes.
11803 * character.c (string_escape_byte8): Likewise.
11804 * lisp.h (string_overflow): New decl.
11806 Fixups, following up to the user-interface timestamp change.
11807 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11808 for UI timestamps, instead of unsigned long.
11809 * msdos.c (mouse_get_pos): Likewise.
11810 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11811 * w32gui.h (Time): Define by including "systime.h" rather than by
11812 declaring it ourselves. (Bug#8664)
11814 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11815 * image.c (clear_image_cache): Likewise.
11817 * term.c (term_mouse_position): Don't assume time_t wraparound.
11819 Be more systematic about user-interface timestamps.
11820 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11821 and sometimes 'EMACS_UINT', to represent these timestamps.
11822 This change causes it to use 'Time' uniformly, as that's what X uses.
11823 This makes the code easier to follow, and makes it easier to catch
11824 integer overflow bugs such as Bug#8664.
11825 * frame.c (Fmouse_position, Fmouse_pixel_position):
11826 Use Time, not unsigned long, for user-interface timestamps.
11827 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11828 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11829 * keyboard.h (last_event_timestamp): Likewise.
11830 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11831 * menu.h (xmenu_show): Likewise.
11832 * term.c (term_mouse_position): Likewise.
11833 * termhooks.h (struct input_event.timestamp): Likewise.
11834 (struct terminal.mouse_position_hook): Likewise.
11835 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11836 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11837 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11838 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11839 what it was before.
11840 * menu.h, termhooks.h: Include "systime.h", for Time.
11842 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11843 Don't assume that the difference between two unsigned long values
11844 can fit into an integer. At this point, we know button_down_time
11845 <= event->timestamp, so the difference must be nonnegative, so
11846 there's no need to cast the result if double-click-time is
11847 nonnegative, as it should be; check that it's nonnegative, just in
11848 case. This bug is triggered when events are more than 2**31 ms
11849 apart (about 25 days). (Bug#8664)
11851 * xselect.c (last_event_timestamp): Remove duplicate decl.
11852 (x_own_selection): Remove needless cast to unsigned long.
11854 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11855 that always fit in int. Use a sentinel instead of a counter, to
11856 avoid a temp and to allay GCC's concerns about possible int overflow.
11857 * frame.h (struct frame): Use int for menu_bar_items_used
11858 instead of EMACS_INT, since it always fits in int.
11860 * menu.c (grow_menu_items): Check for int overflow.
11862 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11864 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11865 Before, the code was not consistent. These values cannot exceed
11866 2**31 - 1 so there's no need to make them unsigned.
11867 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11868 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11869 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11871 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11873 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11874 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11875 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11876 presumably because the widths might not match.
11878 * window.c (size_window): Avoid needless test at loop start.
11880 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11882 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11884 2011-05-12 Drew Adams <drew.adams@oracle.com>
11886 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11888 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11890 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11891 `width' to `bar_area_x' and `bar_area_width', respectively.
11892 (x_scroll_run): Take account of fringe background extension.
11894 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11895 Rename local vars `left' and `width' to `bar_area_x' and
11896 `bar_area_width', respectively.
11897 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11898 background extension.
11900 2011-05-10 Jim Meyering <meyering@redhat.com>
11902 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11904 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11906 * image.c (Finit_image_library): Return t for built-in image types,
11907 like pbm and xbm. (Bug#8640)
11909 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11911 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11913 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11915 * w32console.c (Fset_screen_color): Doc fix.
11916 (Fget_screen_color): New function.
11917 (syms_of_ntterm): Defsubr it.
11919 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11920 unlink the temporary file if Fcall_process didn't create it in the
11922 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11923 child process will be redirected to a file specified with `:file'.
11924 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11925 cue to call_process_cleanup not to close that handle.
11927 2011-05-07 Ben Key <bkey76@gmail.com>
11929 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11930 one of two shell specific rules, either bootstrap-temacs-CMD or
11931 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11932 to the previous implementation of the bootstrap-temacs rule.
11933 The bootstrap-temacs-CMD rule is similar to the previous
11934 implementation of the bootstrap-temacs rule except that it
11935 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11938 These changes, along with some changes to nt/configure.bat,
11939 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11940 earlier fix to add support for --cflags and --ldflags options
11941 that include quotes so that it works whether make uses cmd or
11944 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11946 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11947 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11949 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11950 a string. Handle both cases.
11951 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11952 (Fdbus_register_method): Use Qinvalid_function.
11954 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11956 * makefile.w32-in: Update dependencies.
11957 (LISP_H): Add inttypes.h and stdin.h.
11958 (PROCESS_H): Add unistd.h.
11960 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11962 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11963 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11965 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11967 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11969 * term.c (vfatal): Remove stray call to va_end.
11970 It's not needed and the C Standard doesn't allow it here anyway.
11972 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11973 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11975 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11978 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11980 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11982 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11984 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11986 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11988 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11989 * charset.c (Fdefine_charset_internal): Don't initialize
11990 charset.code_space[15]. The value was garbage, on hosts with
11991 32-bit int (Bug#8600).
11993 * lread.c (read_integer): Be more consistent with string-to-number.
11994 Use string_to_number to do the actual conversion; this avoids
11995 rounding errors and fixes some other screwups. Without this fix,
11996 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11997 (digit_to_number): Move earlier, for benefit of read_integer.
11998 Return -1 if the digit is out of range for the base, -2 if it is
11999 not a digit in any supported base. (Bug#8602)
12001 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12003 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12004 to match comment at start of function. This also removes a
12005 GCC warning about overflow in a 32+64-bit port.
12007 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12009 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12010 Reported by Stefan Monnier in
12011 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12012 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12013 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12015 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12016 (EMACS_UINTPTR): Likewise, with uintptr_t.
12018 * lisp.h: Prefer 64-bit EMACS_INT if available.
12019 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12020 on 32-bit hosts that have 64-bit int, so that they can access
12022 However, temporarily disable this change unless the temporary
12023 symbol WIDE_EMACS_INT is defined.
12025 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12027 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12028 This removes an assumption that EMACS_INT and long are the same
12029 width as pointers. The assumption is true for Emacs porting targets
12030 now, but we want to make other targets possible.
12031 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12032 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12033 In the rest of the code, change types of integers that hold casted
12034 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12035 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12036 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12037 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12038 No need to cast type when ORing.
12039 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12040 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12041 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12042 assume EMACS_INT is the same width as char *.
12043 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12044 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12045 Remove no-longer-needed casts.
12046 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12047 (xg_tool_bar_help_callback, xg_make_tool_item):
12048 Use EMACS_INTPTR to hold an integer
12049 that will be cast to void *; this can avoid a GCC warning
12050 if EMACS_INT is not the same width as void *.
12051 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12052 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12053 (current_message_1, set_message_1):
12054 Use a local to convert to proper width without a cast.
12055 * xmenu.c (dialog_selection_callback): Likewise.
12057 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12058 Also, don't assume VALBITS / RAND_BITS is less than 5,
12059 and don't rely on undefined behavior when shifting a 1 left into
12061 * lisp.h (get_random): Change signature to match.
12063 * lread.c (hash_string): Use size_t, not int, for hash computation.
12064 Normally we prefer signed values; but hashing is special, because
12065 it's better to use unsigned division on hash table sizes so that
12066 the remainder is nonnegative. Also, size_t is the natural width
12067 for hashing into memory. The previous code used 'int', which doesn't
12068 retain enough info to hash well into very large tables.
12069 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12071 * dbusbind.c: Don't possibly lose pointer info when converting.
12072 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12073 Use XPNTR rather than XHASH, so that the high-order bits of
12074 the pointer aren't lost when converting through void *.
12076 * eval.c (Fautoload): Don't double-shift a pointer.
12078 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12080 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12082 * gnutls.c (DEF_GNUTLS_FN):
12083 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12085 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12087 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12090 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12092 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12093 New version that can reserve upto 2GB of heap space.
12095 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12097 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12099 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12101 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12102 `gnutls_certificate_set_x509_key_file'.
12104 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12106 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12107 Update dependencies.
12109 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12111 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12112 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12113 Remove unused parameter `fildes'.
12114 * process.c (read_process_output, send_process): Don't pass it.
12116 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12118 Fix previous change: the library cache is defined in w32.c.
12119 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12120 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12122 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12124 Implement dynamic loading of GnuTLS on Windows.
12126 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12127 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12128 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12131 * gnutls.c (Qgnutls_dll): Define.
12132 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12133 (gnutls_*): Declare function pointers.
12134 (init_gnutls_functions): New function to initialize function pointers.
12135 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12136 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12137 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12138 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12139 (emacs_gnutls_write, emacs_gnutls_read)
12140 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12141 (Fgnutls_available_p): New function.
12142 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12143 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12144 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12146 * image.c: Include w32.h.
12147 (Vimage_type_cache): Delete.
12148 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12149 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12150 (w32_delayed_load): Move to w32.c.
12152 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12154 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12155 (w32_delayed_load): Move from image.c. When loading a library, record
12156 its filename in the :loaded-from property of the library id.
12157 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12158 Initialize and staticpro them.
12159 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12161 * process.c: Include lisp.h before w32.h, not after.
12162 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12163 instead of gnutls_record_check_pending.
12165 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12167 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12169 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12170 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12173 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12175 * xterm.c (x_set_frame_alpha): Do not set property on anything
12176 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12178 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12180 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12182 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12184 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12185 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12191 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12192 (Qgnutls_bootprop_callbacks_verify): Make static.
12194 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>

12204 * sysdep.c (interruptible_wait_for_termination): New function
12205 which is like wait_for_termination, but allows keyboard
12208 * callproc.c (Fcall_process): Add (:file "file") as an option for
12210 (Fcall_process_region): Ditto.
12212 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12214 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12215 rather than `XVECTOR (FOO)->size'.
12217 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12218 inttypes.h, as a gnulib replacement is used if it not available in
12221 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12223 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12224 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12225 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12227 * coding.c (coding_alloc_by_realloc): Error out if destination
12228 will grow beyond MOST_POSITIVE_FIXNUM.
12229 (decode_coding_emacs_mule): Abort if there isn't enough place in
12230 charbuf for the composition carryover bytes. Reserve an extra
12231 space for up to 2 characters produced in a loop.
12232 (decode_coding_iso_2022): Abort if there isn't enough place in
12233 charbuf for the composition carryover bytes.
12235 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12237 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12238 aborting when %lld or %lll format is passed.
12239 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12240 %llo or %llx format is passed. (Bug#8545)
12242 * window.c (window_scroll_line_based): Use a marker instead of
12243 simple variables to record original value of point. (Bug#7952)
12245 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12246 produced by %s or %c overflows available buffer space. (Bug#8545)
12248 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12250 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12251 (SIZE_MAX): Move defn after all includes, as they might #define it.
12253 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12255 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12257 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12259 * keyboard.c (Qdelayed_warnings_hook): Define.
12260 (command_loop_1): Run `delayed-warnings-hook'
12261 if Vdelayed_warnings_list is non-nil.
12262 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12263 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12265 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12267 * doprnt.c (doprnt): Don't return value smaller than the buffer
12268 size if the message was truncated. (Bug#8545).
12270 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12272 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12273 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12275 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12277 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12279 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12281 * makefile.w32-in: Update dependencies.
12283 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12285 Improve `doprnt' and its usage. (Bug#8545)
12286 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12287 `format_end'. Remove support for %l as a conversion specifier.
12288 Don't use xrealloc. Improve diagnostics when the %l size modifier
12289 is used. Update the commentary.
12291 * eval.c (verror): Simplify calculation of size_t.
12293 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12296 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12298 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12301 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12303 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12304 This makes this file independent of the recent pseudovector change.
12306 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12308 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12310 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12311 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12312 Remove unused local.
12313 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12315 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12316 GCC 4.6.0 optimizes based on type-based alias analysis.
12317 For example, if b is of type struct buffer * and v of type struct
12318 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12319 != &v->size, and therefore "v->size = 1; b->size = 2; return
12320 v->size;" must therefore return 1. This assumption is incorrect
12321 for Emacs, since it type-puns struct Lisp_Vector * with many other
12322 types. To fix this problem, this patch adds a new type struct
12323 vectorlike_header that documents the constraints on layout of vectors
12324 and pseudovectors, and helps optimizing compilers not get fooled
12325 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12326 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12327 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12329 (XSETPVECTYPE): Rewrite in terms of new macro.
12330 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12331 This is a bit clearer, and further avoids the possibility of
12332 undesirable aliasing.
12333 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12334 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12335 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12336 since Lisp_Subr is a special case (no "next" field).
12337 (ASIZE): Now uses header.size rather than size.
12338 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12339 to avoid the hassle of writing XVECTOR (foo)->header.size.
12340 (struct vectorlike_header): New type.
12341 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12342 object, to help avoid aliasing.
12343 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12344 (SUBRP): Likewise, since Lisp_Subr is a special case.
12345 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12346 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12347 (struct Lisp_Hash_Table): Combine first two members into a single
12348 struct vectorlike_header member. All uses of "size" and "next" members
12349 changed to be "header.size" and "header.next".
12350 * buffer.h (struct buffer): Likewise.
12351 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12352 * frame.h (struct frame): Likewise.
12353 * process.h (struct Lisp_Process): Likewise.
12354 * termhooks.h (struct terminal): Likewise.
12355 * window.c (struct save_window_data, struct saved_window): Likewise.
12356 * window.h (struct window): Likewise.
12357 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12358 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12359 * buffer.c (init_buffer_once): Likewise.
12360 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12362 * process.c (Fformat_network_address): Use local var for size,
12365 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12367 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12368 * data.c (atof): Remove decl; no longer used or needed.
12369 (digit_to_number): Move to lread.c.
12370 (Fstring_to_number): Use new string_to_number function, to be
12371 consistent with how the Lisp reader treats infinities and NaNs.
12372 Do not assume that floating-point numbers represent EMACS_INT
12373 without losing information; this is not true on most 64-bit hosts.
12374 Avoid double-rounding errors, by insisting on integers when
12375 parsing non-base-10 numbers, as the documentation specifies.
12376 * lisp.h (string_to_number): New decl, replacing ...
12377 (isfloat_string): Remove.
12378 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12379 (read1): Do not accept +. and -. as integers; this
12380 appears to have been a coding error. Similarly, do not accept
12381 strings like +-1e0 as floating point numbers. Do not report
12382 overflow for integer overflows unless the base is not 10 which
12383 means we have no simple and reliable way to continue.
12384 Break out the floating-point parsing into a new
12385 function string_to_number, so that Fstring_to_number parses
12386 floating point numbers consistently with the Lisp reader.
12387 (digit_to_number): Move here from data.c. Make it static inline.
12388 (E_CHAR, EXP_INT): Remove, replacing with ...
12389 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12390 (string_to_number): New function, replacing isfloat_string.
12391 This function checks for valid syntax and produces the resulting
12392 Lisp float number too. Rework it so that string-to-number
12393 no longer mishandles examples like "1.0e+". Use strtoumax,
12394 so that overflow for non-base-10 numbers is reported only when
12395 there's no portable and simple way to convert to floating point.
12397 * textprop.c (set_text_properties_1): Rewrite for clarity,
12398 and to avoid GCC warning about integer overflow.
12400 * intervals.h (struct interval): Use EMACS_INT for members
12401 where EMACS_UINT might cause problems. See
12402 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12403 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12404 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12406 (offset_intervals): Tell GCC not to worry about length overflow
12407 when negating a negative length.
12409 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12410 (overrun_check_free): Likewise.
12412 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12413 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12416 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12417 (gnutls_make_error): Rename local to avoid shadowing.
12418 (gnutls_emacs_global_deinit): ifdef out; not used.
12419 (Fgnutls_boot): Use const for pointer to readonly storage.
12420 Comment out unused local. Fix pointer signedness problems.
12422 * lread.c (openp): Don't stuff size_t into an 'int'.
12423 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12424 about possible signed overflow.
12426 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12427 (GDK_KEY_g): Don't define if already defined.
12428 (xg_prepare_tooltip): Avoid pointer signedness problem.
12429 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12431 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12432 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12434 * xfns.c (Fx_window_property): Simplify a bit,
12435 to make a bit faster and to avoid GCC 4.6.0 warning.
12436 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12438 * fns.c (internal_equal): Don't assume size_t fits in int.
12440 * alloc.c (compact_small_strings): Tighten assertion a little.
12442 Replace pEd with more-general pI, and fix some printf arg casts.
12443 * lisp.h (pI): New macro, generalizing old pEd macro to other
12444 conversion specifiers. For example, use "...%"pI"d..." rather
12445 than "...%"pEd"...".
12446 (pEd): Remove. All uses replaced with similar uses of pI.
12447 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12448 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12449 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12450 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12451 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12452 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12453 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12455 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12456 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12457 * print.c (safe_debug_print, print_object): Likewise.
12458 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12460 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12461 avoiding the 0 flag, which is not portable.
12462 * process.c (Fmake_network_process): Use pI to avoid cast.
12463 * region-cache.c (pp_cache): Likewise.
12464 * xdisp.c (decode_mode_spec): Likewise.
12465 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12466 behavior on 64-bit hosts with printf arg.
12467 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12468 (x_stop_queuing_selection_requests): Likewise.
12469 (x_get_window_property): Don't truncate byte count to an 'int'
12472 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12473 here, since it parses constructs like leading '-' and spaces,
12474 which are not wanted; and it overflows with large numbers.
12475 Instead, simply match F[0-9]+, which is what is wanted anyway.
12477 * alloc.c: Remove unportable assumptions about struct layout.
12478 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12479 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12480 (allocate_vectorlike, make_pure_vector): Use the new macros,
12481 plus offsetof, to remove unportable assumptions about struct layout.
12482 These assumptions hold on all porting targets that I know of, but
12483 they are not guaranteed, they're easy to remove, and removing them
12484 makes further changes easier.
12486 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12487 This doesn't fix a bug but makes the code clearer.
12488 (string_overrun_cookie): Now const. Use initializers that
12489 don't formally overflow signed char, to avoid warnings.
12490 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12491 can cause Emacs to crash when string overrun checking is enabled.
12492 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12493 multiple of sizeof (EMACS_INT); it need not be, if
12494 alignof(EMACS_INT) < sizeof (EMACS_INT).
12495 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12497 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12499 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12501 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12503 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12504 supposed to be handshaking. (Bug#8556)
12505 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12507 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

12512 (handle_user_signal): Break into debugger when debug-on-event
12513 matches the current signal symbol.
12515 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12517 * alloc.c (check_sblock, check_string_bytes)
12518 (check_string_free_list): Convert to standard C.
12520 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12522 * w32.c (emacs_gnutls_push): Fix typo.
12524 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12526 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12527 "cast to pointer from integer of different size".
12529 Improve doprnt and its use in verror. (Bug#8545)
12530 * doprnt.c (doprnt): Document the set of format control sequences
12531 supported by the function. Use SAFE_ALLOCA instead of always
12534 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12535 is one byte too soon. Don't use xrealloc; instead xfree and
12538 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12540 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12543 * gnutls.c: Renamed global_initialized to
12544 gnutls_global_initialized. Added internals for the
12545 :verify-hostname-error, :verify-error, and :verify-flags
12546 parameters of `gnutls-boot' and documented those parameters in the
12547 docstring. Start callback support.
12548 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12549 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12550 on error. Return error code.
12551 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12552 (emacs_gnutls_read): Likewise.
12553 (Fgnutls_boot): Return handshake error code.
12554 (emacs_gnutls_handle_error): New function.
12555 (wsaerror_to_errno): Likewise.

12560 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12561 (emacs_gnutls_push): Likewise.
12563 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
12565 * process.c (wait_reading_process_output): Check if GnuTLS
12566 buffered some data internally if no FDs are set for TLS
12569 * makefile.w32-in (OBJ2): Add gnutls.$(O).
12570 (LIBS): Link to USER_LIBS.

12576 display_replaced_before_p argument into display_replaced_p, to
12577 make it consistent with the commentary. Fix typos in the
12580 * textprop.c (syms_of_textprop): Remove dead code.

12592 to changes in oldXMenu/XMenu.h from 2011-04-16.
12593 (struct XMenu): Declare `help_text' `const char **'.

12610 changes in globals.h immediately force recompilation.
12611 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12612 $(CURDIR)/s/ms-w32.h.
12613 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

12617 <char-direction-table>: Deleted.
12619 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12621 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12622 * doprnt.c: Include limits.h.
12623 (SIZE_MAX): New macro.
12624 (doprnt): Return a size_t value. 2nd arg is now size_t.
12625 Many local variables are now size_t instead of int or unsigned.
12626 Improve overflow protection. Support `l' modifier for integer
12627 conversions. Support %l conversion. Don't assume an EMACS_INT
12628 argument for integer conversions and for %c.
12630 * lisp.h (doprnt): Restore prototype.
12632 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12633 $(SRC)/character.h.
12635 * Makefile.in (base_obj): Add back doprnt.o.
12637 * deps.mk (doprnt.o): Add back prerequisites.
12638 (callint.o): Depend on character.h.

12878 * process.c (send_process): Adjust to the new signatures of
12879 emacs_write and emacs_gnutls_write. Do not attempt to store

13105 worth the hassle of breaking this out.
13107 * xterm.c: Make symbols static if they're not exported.
13108 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
13109 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

13208 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
13209 * lisp.h: Remove these decls.
13211 * buffer.c (buffer_count): Remove unused var.
13213 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
13214 so that it's not optimized away.
13215 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13216 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13217 exported only to the debugger.

13220 * atimer.h (run_all_atimers): Remove; not exported.
13222 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13223 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13224 was inaccessible from Lisp.
13225 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13226 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13228 alloc.c: Import and export fewer symbols, and remove unused items.
13229 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13231 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13232 it's not optimized away by whole-program optimization.
13233 (message_enable_multibyte, free_misc): Remove.
13234 (catchlist, handlerlist, mark_backtrace):
13235 Declare only if BYTE_MARK_STACK.

13244 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13245 (mark_backtrace): Define only if BYTE_MARK_STACK.
13246 * xdisp.c (message_enable_multibyte): Now static.
13248 Declare Lisp_Object Q* variables to be 'static' if not exported.
13249 This makes it easier for human readers (and static analyzers)
13250 to see whether these variables are used from other modules.
13251 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13252 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13253 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

13260 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
13261 Remove decls of unexported vars.
13262 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13264 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13266 Make Emacs functions such as Fatom 'static' by default.
13267 This makes it easier for human readers (and static analyzers)
13268 to see whether these functions can be called from other modules.
13269 DEFUN now defines a static function. To make the function external
13270 so that it can be used in other C modules, use the new macro DEFUE.
13271 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13272 (Finit_image_library):
13273 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13274 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13275 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13276 Remove decls, since these functions are now static.
13277 (Funintern, Fget_internal_run_time): New decls, since these functions
13278 were already external.
13280 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13281 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13287 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13288 Mark functions with DEFUE instead of DEFUN,
13289 if they are used in other modules.
13290 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13291 decls for now-static functions.
13292 * buffer.h (Fdelete_overlay): Remove decl.
13293 * callproc.c (Fgetenv_internal): Mark as internal.
13294 * composite.c (Fremove_list_of_text_properties): Remove decl.

13300 (Funintern): Remove extern decl; now in .h file where it belongs.
13301 * fileio.c (Fmake_symbolic_link): New forward static decl.
13302 * image.c (Finit_image_library): New forward static decl.
13303 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13304 * intervals.h (Fprevious_property_change):
13305 (Fremove_list_of_text_properties): Remove decls.
13306 * keyboard.c (Fthis_command_keys): Remove decl.
13307 (Fcommand_execute): New forward static decl.
13308 * keymap.c (Flookup_key): New forward static decl.
13309 (Fcopy_keymap): Now static.
13310 * keymap.h (Flookup_key): Remove decl.
13311 * process.c (Fget_process): New forward static decl.
13312 (Fprocess_datagram_address): Mark as internal.

13323 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13325 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13328 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13330 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13331 when at ZV. (Bug#8487)
13333 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13335 * charset.c (Fclear_charset_maps): Use xfree instead of free.

13339 * termcap.c (tgetent): Likewise.
13340 * xfns.c (x_default_font_parameter): Likewise.
13341 * xsettings.c (read_and_apply_settings): Likewise.
13343 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13344 (overrun_check_free): Protoize.
13346 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13348 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13349 since callers should never pass a negative size.
13350 Change the signature to match that of plain 'read' and 'write'; see
13351 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13352 * lisp.h: Update prototypes of emacs_write and emacs_read.
13354 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13356 * xdisp.c (redisplay_window): Don't try to determine the character
13357 position of the scroll margin if the window start point w->startp
13358 is outside the buffer's accessible region. (Bug#8468)
13360 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13362 Fix write-region and its subroutines for buffers > 2GB.
13363 * fileio.c (a_write, e_write): Modify declaration of arguments and
13364 local variables to support buffers larger than 2GB.
13365 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13367 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13368 argument, local variables, and return value.
13370 * lisp.h: Update prototypes of emacs_write and emacs_read.
13372 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13374 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13376 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13378 Fix more problems found by GCC 4.6.0's static checks.
13380 * xdisp.c (vmessage): Use a better test for character truncation.
13382 * charset.c (load_charset_map): <, not <=, for optimization,
13383 and to avoid potential problems with integer overflow.
13384 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13385 * casetab.c (set_identity, shuffle): Likewise.
13386 * editfns.c (Fformat): Likewise.
13387 * syntax.c (skip_chars): Likewise.
13389 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13390 This also lets GCC 4.6.0 generate slightly better loop code.
13392 * callint.c (Fcall_interactively): <, not <=, for optimization.
13393 (Fcall_interactively): Count the number of arguments produced,
13394 not the number of arguments given. This is simpler and lets GCC
13395 4.6.0 generate slightly better code.
13397 * ftfont.c: Distingish more carefully between FcChar8 and char.
13398 The previous code passed unsigned char * to a functions like
13399 strlen and xstrcasecmp that expect char *, which does not
13400 conform to the C standard.
13401 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13402 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13403 char * when the C standard requires it.
13405 * keyboard.c (read_char): Remove unused var.
13407 * eval.c: Port to Windows vsnprintf (Bug#8435).
13408 Include <limits.h>.
13409 (SIZE_MAX): Define if the headers do not.
13410 (verror): Do not give up if vsnprintf returns a negative count.
13411 Instead, grow the buffer. This ports to Windows vsnprintf, which
13412 does not conform to C99. Problem reported by Eli Zaretskii.
13413 Also, simplify the allocation scheme, by avoiding the need for
13414 calling realloc, and removing the ALLOCATED variable.
13416 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13418 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13419 But keep the doprint source code for now, as we might revamp it
13420 and use it again (Bug#8435).
13421 * lisp.h (doprnt): Remove.
13422 * Makefile.in (base_obj): Remove doprnt.o.
13423 * deps.mk (doprnt.o): Remove.
13425 error: Print 32- and 64-bit integers portably (Bug#8435).
13426 Without this change, on typical 64-bit hosts error ("...%d...", N)
13427 was used to print both 32- and 64-bit integers N, which relied on
13428 undefined behavior.
13429 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13430 * lisp.h (error, verror): Mark as printf-like functions.
13431 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13432 Report overflow in size calculations when allocating printf buffer.
13433 Do not truncate output string at its first null byte.
13434 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13435 Truncate the output at a character boundary, since vsnprintf does not
13437 * charset.c (check_iso_charset_parameter): Convert internal
13438 character to string before calling 'error', since %c now has the
13440 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13441 overflow when computing char to be passed to 'error'. Do not
13442 pass Lisp_Object to 'error'; pass the integer instead.
13443 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13444 formatted with plain %d.
13446 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13448 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13450 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13452 * xterm.c (x_catch_errors): Remove duplicate declaration.
13454 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13456 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13458 2011-04-10 Jim Meyering <meyering@redhat.com>
13460 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13461 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13462 return ssize_t not "int", and use size_t as the buffer length.
13463 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13464 * gnutls.h: Update declarations.
13465 * process.c (read_process_output): Use ssize_t, to match.
13466 (send_process): Likewise.
13468 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13470 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13472 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13474 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13475 Use unsigned char, to match FcChar8 type definition.
13477 * xterm.c (handle_one_xevent):
13478 * xmenu.c (create_and_show_popup_menu):
13479 * xselect.c (x_decline_selection_request)
13480 (x_reply_selection_request): Avoid type-punned deref of X events.
13482 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13484 Fix some uses of `int' instead of EMACS_INT.
13485 * search.c (string_match_1, fast_string_match)
13486 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13487 (scan_buffer, find_next_newline_no_quit)
13488 (find_before_next_newline, search_command, Freplace_match)
13489 (Fmatch_data): Make some `int' variables be EMACS_INT.
13491 * xdisp.c (display_count_lines): 3rd argument and return value now
13492 EMACS_INT. All callers changed.
13493 (pint2hrstr): Last argument is now EMACS_INT.
13495 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13496 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

13500 (decode_coding_ccl, decode_coding_charset)
13501 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

13503 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)

13538 instead of using internal_with_output_to_temp_buffer.
13539 (Qhelp_form_show): New var.
13540 (syms_of_keyboard): Use DEFSYM macro.
13542 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13565 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13567 * xdisp.c (vmessage): Mark as a printf-like function.
13569 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

13576 to system-supplied API.
13578 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13580 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13581 This avoids several warnings with gcc -Wstrict-overflow.
13582 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13583 directly, rather than having caller test rule sign. This avoids
13584 some unnecessary tests.
13585 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13586 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13587 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13589 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13590 (xfont_open): Avoid unnecessary tests.
13592 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13594 * composite.h, composite.c (composition_gstring_put_cache):
13595 Use EMACS_INT, not int, for length.
13597 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13598 breaking out part of COMPOSITION_DECODE_RULE.
13599 (COMPOSITION_DECODE_RULE): Use it.
13600 * composite.c (get_composition_id): Remove unused local vars,
13601 by using the new macro.
13603 * textprop.c (set_text_properties_1): Change while to do-while,
13604 since the condition is always true at first.
13606 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13607 (interval_deletion_adjustment): Return unsigned value.
13610 * process.c (list_processes_1, create_pty, read_process_output):
13611 (exec_sentinel): Remove vars that were set but not used.
13612 (create_pty): Remove unnecessary "volatile"s.
13613 (Fnetwork_interface_info): Avoid possibility of int overflow.
13614 (read_process_output): Do adaptive read buffering even if carryover.
13615 (read_process_output): Simplify nbytes computation if buffered.
13617 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
13619 * syntax.c (scan_words): Remove var that was set but not used.
13620 (update_syntax_table): Use unsigned instead of int.
13622 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

13626 * print.c (print_error_message): Avoid int overflow.
13628 * font.c (font_list_entities): Redo for clarity,
13629 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13631 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13632 (font_score): Avoid potential overflow in diff calculation.
13634 * fns.c (substring_both): Remove var that is set but not used.
13635 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13637 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13639 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13640 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13641 can always succeed if overflow has undefined behavior.
13643 * search.c (boyer_moore, wordify): Remove vars set but not used.
13644 (wordify): Omit three unnecessary tests.
13646 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13647 All callers changed. This avoids the need for an unused var.

13651 * dired.c (file_name_completion): Remove var that is set but not used.
13653 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13655 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13656 (Finsert_file_contents): Remove unnecessary code checking fd.
13658 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13659 Check for integer overflow on size calculations.
13661 * buffer.c (Fprevious_overlay_change): Remove var that is set
13664 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13665 Remove vars that are set but not used.
13666 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13667 (timer_check_2): Mark vars as initialized.
13669 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13671 * image.c (lookup_image): Remove var that is set but not used.
13672 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13674 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13675 that are set but not used.
13677 * xfns.c (make_invisible_cursor): Don't return garbage
13678 if XCreateBitmapFromData fails (Bug#8410).
13680 * xselect.c (x_get_local_selection, x_handle_property_notify):
13681 Remove vars that are set but not used.
13683 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13684 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13686 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13687 Remove var that is set but not used.
13688 (scroll_bar_windows_size): Now size_t, not int.
13689 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13690 Check for overflow.
13692 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13693 (map_tty_color) [!defined MSDOS]: Likewise.
13695 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13697 * coding.c: Remove vars that are set but not used.
13698 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13699 All callers changed.
13700 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13701 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13702 (decode_coding_charset): Remove vars that are set but not used.
13704 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13705 that is set but not used.
13707 * print.c (print_object): Remove var that is set but not used.
13709 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13710 The gnulib version avoids calling malloc in the usual case,
13711 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13712 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13713 * filelock.c (current_lock_owner): Likewise.
13714 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13715 * sysdep.c: Include allocator.h, careadlinkat.h.
13716 (emacs_no_realloc_allocator): New static constant.
13717 (emacs_readlink): New function.
13718 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13719 ../lib/careadlinkat.h.
13721 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13723 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13724 first non-nil return value).
13726 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13728 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13729 if not defined (Bug#8403).
13731 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13733 * xdisp.c (display_count_lines): Remove parameter `start',
13734 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13735 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13736 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13738 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13739 and thereabouts. All callers changed.
13740 (get_per_char_metric): Remove parameter `f', unused since
13741 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13743 2011-04-02 Jim Meyering <meyering@redhat.com>
13745 do not dereference NULL upon failed strdup
13746 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13747 (ns_get_family): Likewise.
13749 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13751 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13753 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13755 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13758 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13760 Add lexical binding.
13762 * window.c (Ftemp_output_buffer_show): New fun.
13763 (Fsave_window_excursion):
13764 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13766 * lread.c (lisp_file_lexically_bound_p): New function.

13771 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13773 (syms_of_lread): Declare `lexical-binding'.
13775 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13777 * keyboard.c (eval_dyn): New fun.
13778 (menu_item_eval_property): Use it.
13780 * image.c (parse_image_spec): Use Ffunctionp.
13782 * fns.c (concat, mapcar1): Accept byte-code-functions.
13784 * eval.c (Fsetq): Handle lexical vars.
13785 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13786 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13787 (FletX, Flet): Obey lexical binding.
13788 (Fcommandp): Handle closures.
13789 (Feval): New `lexical' arg.
13790 (eval_sub): New function extracted from Feval. Use it almost
13791 everywhere where Feval was used. Look up vars in lexical env.
13793 (Ffunctionp): Move from subr.el.
13794 (Ffuncall): Handle closures.
13795 (apply_lambda): Remove `eval_flags'.
13796 (funcall_lambda): Handle closures and new byte-code-functions.
13797 (Fspecial_variable_p): New function.
13798 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13799 but without exporting it to Lisp.
13801 * doc.c (Fdocumentation, store_function_docstring):
13802 * data.c (Finteractive_form): Handle closures.
13804 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13807 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13809 (exec_byte_code): New function extracted from Fbyte_code to handle new
13810 calling convention for byte-code-functions. Add new byte-codes.
13812 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13814 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13816 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13818 * xdisp.c (redisplay_internal): Fix prototype.
13820 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13822 * xdisp.c (SCROLL_LIMIT): New macro.
13823 (try_scrolling): Use it when setting scroll_limit.
13824 Limit scrolling to 100 screen lines.
13825 (redisplay_window): Even when falling back on "recentering",
13826 position point in the window according to scroll-conservatively,
13827 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13829 (try_scrolling): When point is above the window, allow searching
13830 as far as scroll_max, or one screenful, to compute vertical
13831 distance from PT to the scroll margin position. This prevents
13832 try_scrolling from unnecessarily failing when
13833 scroll-conservatively is set to a value slightly larger than the
13834 window height. Clean up the case of PT below the margin at bottom
13835 of window: scroll_max can no longer be INT_MAX. When aggressive
13836 scrolling is in use, don't let point enter the opposite scroll
13837 margin as result of the scroll.
13838 (syms_of_xdisp) <scroll-conservatively>: Document the
13839 threshold of 100 lines for never-recentering scrolling.
13841 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13843 * dispextern.h (move_it_by_lines):
13844 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13845 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13846 (message_log_check_duplicate): Remove parameters `prev_bol' and
13847 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13848 (redisplay_internal): Remove parameter `preserve_echo_area',
13849 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13851 * indent.c (Fvertical_motion):
13852 * window.c (window_scroll_pixel_based, Frecenter):
13853 Don't pass `need_y_p' to `move_it_by_lines'.
13855 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13857 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13858 steal a few bits to be more compact.
13859 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13860 Remove unneeded casts.
13862 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13864 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13866 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13867 binding" message (bug#7967).
13869 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13871 Fix more problems found by GCC 4.6.0's static checks.
13873 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13874 Remove unused local var.
13876 * editfns.c (Fmessage_box): Remove unused local var.
13878 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13879 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13880 Omit unused local vars.
13881 * window.c (shrink_windows): Omit unused local var.
13882 * menu.c (digest_single_submenu): Omit unused local var.
13883 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13884 Omit unused local var.
13886 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13887 Don't assume string length fits in int.
13888 (keyremap_step, read_key_sequence): Use size_t for sizes.
13889 (read_key_sequence): Don't check last_real_key_start redundantly.
13891 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13892 instead of alloca (Bug#8344).
13894 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13895 (Fbacktrace_frame): Don't assume nframes fits in int.
13897 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

13902 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13904 * cm.c (calccost): Turn while-do into do-while, for clarity.
13906 * keyboard.c (syms_of_keyboard): Use the same style as later
13907 in this function when indexing through an array. This also
13908 works around GCC bug 48267.
13910 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13912 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13914 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13915 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13917 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13918 This avoids undefined behavior on integer overflow, and is a bit
13919 more convenient anyway since it is compared to a size_t variable.
13921 Variadic C functions now count arguments with size_t, not int.
13922 This avoids an unnecessary limitation on 64-bit machines, which
13923 caused (substring ...) to crash on large vectors (Bug#8344).
13924 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13925 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13926 All variadic functions and their callers changed accordingly.

13933 * fns.c (concat): Likewise.
13934 * frame.c (x_set_frame_parameters): Likewise.
13935 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13936 0 if not found, not -1. All callers changed.
13938 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13939 (stack_copy_size): Now size_t, not int.
13940 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13942 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13944 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13945 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13946 All callers changed.
13948 * lisp.h (multibyte_char_to_unibyte):
13949 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13950 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13954 * keymap.c (push_key_description):
13955 * search.c (Freplace_match):
13956 * xdisp.c (message_dolog, set_message_1): All callers changed.
13958 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13960 * keyboard.c (safe_run_hook_funcall): New function.
13961 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13962 don't set the hook to nil, but remove the offending function instead.
13963 (Qcommand_hook_internal): Remove, unused.
13964 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13965 Vcommand_hook_internal.
13967 * eval.c (enum run_hooks_condition): Remove.

14146 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14148 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14149 unconditionally since it does the check itself.
14151 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14153 Fix more problems found by GCC 4.5.2's static checks.
14155 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14156 the first time through the loop, since we know p0 < p1 then.
14157 This also avoids a gcc -Wstrict-overflow warning.
14159 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14160 leading to a memory leak, possible in functions like
14161 load_charset_map_from_file that can allocate an unbounded number
14162 of objects (Bug#8318).
14164 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14165 that could (at least in theory) be that large.
14167 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14168 This is less likely to overflow, and avoids undefined behavior if
14169 overflow does occur. All callers changed. Use strtoul to scan
14170 for the unsigned long integer.

14187 * process.c (Fmake_network_process): Use socklen_t, not int,
14188 where POSIX says socklen_t is required in portable programs.
14189 This fixes a porting bug on hosts like 64-bit HP-UX, where
14190 socklen_t is wider than int (Bug#8277).
14191 (Fmake_network_process, server_accept_connection):
14192 (wait_reading_process_output, read_process_output):
14195 * process.c: Rename or move locals to avoid shadowing.

14205 Make tparam.h and terminfo.c consistent.
14206 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14207 Include tparam.h instead, since it declares them.
14208 * cm.h (PC): Remove extern decl; tparam.h now does this.
14209 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14210 * terminfo.c: Include tparam.h, to check interfaces.
14211 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14212 (tparam): Adjust signature to match interface in tparam.h;
14213 this removes some undefined behavior. Check that outstring and len
14214 are zero, which they always are with Emacs.
14215 * tparam.h (PC, BC, UP): New extern decls.
14217 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14218 (xftfont_open): Rename locals to avoid shadowing.

14257 Fix pointer signedness.
14258 (alsa_choose_format): Remove unused local var.
14259 (wav_play): Initialize a variable to 0, to prevent undefined
14260 behavior (Bug#8278).
14262 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14264 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14266 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14267 clobbering (Bug#8298).
14268 * sysdep.c (sys_subshell): Likewise.
14269 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14271 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14272 This should get cleaned up, so that child_setup has the
14273 same signature on all platforms.
14275 * callproc.c (call_process_cleanup): Now static.
14276 (relocate_fd): Rename locals to avoid shadowing.
14278 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14280 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14281 not to be necessary, and produces flickering.
14283 2011-03-20 Glenn Morris <rgm@gnu.org>
14285 * config.in: Remove file.
14287 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

14420 gcc -Wbad-function-cast warning.
14421 (default_value, arithcompare, arith_driver, arith_error): Now static.
14422 (store_symval_forwarding): Rename local to avoid shadowing.
14423 (Fmake_variable_buffer_local, Fmake_local_variable):

14430 (mark_stack): Move local variables into the #ifdef region where
14432 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
14433 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
14435 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
14436 (GC_STRING_CHARS): Remove; not used.
14437 (Fmemory_limit): Cast sbrk's returned value to char *.
14439 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14440 avoids undefined behavior in theory.
14442 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14444 Use functions, not macros, for up- and down-casing (Bug#8254).
14445 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14446 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14447 to use the following functions instead of these macros.
14448 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14449 EMACS_INT, since callers assume the returned value fits in int.
14450 (upcase1): Likewise, for UPCASE_TABLE.
14451 (uppercasep, lowercasep, upcase): New static inline functions.
14452 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14453 the race-condition problem in the old DOWNCASE.
14455 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
14456 Rename locals to avoid shadowing.
14457 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.

14461 which gcc can warn about.
14462 (regex_compile, re_match_2_internal): Mark locals as initialized.
14463 (RETALLOC_IF): Define only if needed.
14464 (WORDCHAR_P): Likewise. This one is never needed, but is used
14465 only in a comment talking about a compiler bug, so put inside
14466 the #if 0 of that comment.
14467 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14468 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14471 * search.c (boyer_moore): Rename locals to avoid shadowing.

14494 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14495 New macros, so that the caller can use some names other than
14496 gcpro1, gcpro2, etc.
14497 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14499 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14500 argument, for consistency with GCPRO2_VAR, etc: it is now the
14501 prefix of the variable, not the variable itself. All uses
14503 * dired.c (directory_files_internal, file_name_completion):
14504 Rename locals to avoid shadowing.
14506 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14507 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14508 dired.c's scmp function, had undefined behavior.
14509 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14510 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14511 * buffer.h: ... to here, because these macros use current_buffer,
14512 and the new implementation with inline functions needs to have
14513 current_buffer in scope now, rather than later when the macros
14515 (downcase, upcase1): New static inline functions.
14516 (DOWNCASE, UPCASE1): Reimplement using these functions.
14517 This avoids undefined behavior in expressions like
14518 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14519 from race conditions in accessing the global variables
14520 case_temp1 and case_temp2.
14521 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14522 * lisp.h (case_temp1, case_temp2): Remove their decls.
14523 * character.h (ASCII_CHAR_P): Move from here ...
14524 * lisp.h: ... to here, so that the inline functions mentioned
14525 above can use them.
14527 * dired.c (directory_files_internal_unwind): Now static.
14529 * fileio.c (file_name_as_directory, directory_file_name):
14530 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14532 (file_name_as_directory): Use const pointers when appropriate.
14533 (Fexpand_file_name): Likewise. In particular, newdir might
14534 point at constant storage, so make it a const pointer.
14535 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14536 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14538 (Fset_file_times, Finsert_file_contents, auto_save_error):

14543 to avoid shadowing.
14545 * marker.c (bytepos_to_charpos): Remove; unused.
14547 * lisp.h (verify_bytepos, count_markers): New decls,
14548 so that gcc does not warn that these functions aren't declared.
14550 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14551 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14552 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14553 (copy_text): Remove unused local var.
14555 * filelock.c (within_one_second): Now static.
14556 (lock_file_1): Rename local to avoid shadowing.
14558 * buffer.c (fix_overlays_before): Mark locals as initialized.
14559 (fix_start_end_in_overlays): Likewise. This function should be
14560 simplified by using pointers-to-pointers, but that's a different
14562 (switch_to_buffer_1): Now static.
14563 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14564 (report_overlay_modification): Rename locals to avoid shadowing.
14566 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14567 Fix pointer signedness issue.
14568 (sys_subshell): Mark local as volatile if checking for lint,
14569 to suppress a gcc -Wclobbered warning that does not seem to be right.
14570 (MAXPATHLEN): Define only if needed.
14572 * process.c (serial_open, serial_configure): Move decls from here ...
14573 * systty.h: ... to here, so that they can be checked.
14575 * fns.c (get_random, seed_random): Move extern decls from here ...
14576 * lisp.h: ... to here, so that they can be checked.
14578 * sysdep.c (reset_io): Now static.
14579 (wait_for_termination_signal): Remove; unused.

14587 (describe_map_tree):
14588 Rename locals to avoid shadowing.

14739 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
