87 * w32.c (init_environment): Change the default values of many
88 environment variables in dflt_envvars[] to NULL, to avoid pushing
89 them into environment when they were not already defined. Remove
90 the code that deletes site-lisp subdirectories from the default
91 value of EMACSLOADPATH, as it is no longer needed.
92 (check_windows_init_file): Now external, not static. Use
93 Vload_path as is, without adding anything, as this function is now
94 called when Vload_path is already set up.
96 * w32.h (check_windows_init_file): Add prototype.
98 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

103 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
104 any, in the DEFALT argument into the root of the Emacs build or
105 installation tree, as appropriate.
107 * callproc.c (init_callproc_1): Call decode_env_path instead of
108 doing its equivalent by hand.
109 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
110 the code that sets Vexec_path run on MS-Windows.
112 * lread.c (init_lread): Add comments to #ifdef's.
114 * msdos.c (dos_set_window_size, IT_update_begin)
115 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

122 Now constants, not macros.
124 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
126 Remove unnecessary casts involving pointers.
127 These casts are no longer needed now that we assume C89 or later,

129 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
130 (make_pure_float, make_pure_vector):
131 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

141 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
142 Remove unnecessary pointer casts.
143 * alloc.c (record_xmalloc): New function.
144 * lisp.h (record_xmalloc): New decl.
145 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
146 more like a function. This is because the pointer cast is not
147 needed. All uses changed.
148 * print.c (print_string, print_error_message): Avoid length recalc.
150 Improve fix for macroexp crash with debugging (Bug#12118).
151 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
152 ARRAY_MARK_FLAG when checking subscripts, because ASET is
153 not supposed to be invoked from the garbage collector.
154 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
155 (gc_aset): New function, which is like ASET but can be
156 used in the garbage collector.

170 (map_w32_filename): Improve commentary. Simplify switch.
171 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
172 headers (most versions of MinGW w32api don't).
173 (get_security_info, create_symbolic_link)
174 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
176 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
177 in the argument file name.

179 GetFileAttributes fails with network-related error codes.
180 (sys_rename): Diagnose renaming of a symlink when the user doesn't
181 have the required privileges.
182 (get_file_security_desc_by_name): Renamed from
183 get_file_security_desc.
184 (stat_worker): New function, with most of the guts of 'stat', and
185 with addition of handling of symlinks and support for 'lstat'. If
186 possible, get file's attributes and security information by
187 handle, not by name. Produce S_IFLNK bit for symlinks, when
189 (stat, lstat): New functions, call 'stat_worker'.
190 (symlink, readlink, careadlinkat): Rewritten to create and resolve
191 symlinks when the underlying filesystem supports them.
193 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
195 Fix macroexp crash on Windows with debugging (Bug#12118).
196 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
197 checking subscripts; problem introduced with the recent
198 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
199 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
200 since it's used in non-static inline functions now.
202 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
203 Don't assume buffer size fits in 'int'. Remove unused local.
205 Use C99-style 'extern inline' if available.

223 * composite.c (COMPOSITE_INLINE):
224 * dispnew.c (DISPEXTERN_INLINE):
225 * sysdep.c (SYSTIME_INLINE):
226 Define to EXTERN_INLINE, so that the corresponding functions
227 are compiled into code.
228 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
229 (INLINE_HEADER_END): New macros.
230 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

252 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
254 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
255 This how ASET and AREF are supposed to work, and makes
256 it easier to think about future improvements. See
257 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
258 * charset.h (set_charset_attr): New function.

509 2012-07-30 Glenn Morris <rgm@gnu.org>
511 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
512 does that unconditionally. Remove file, which is now empty.
514 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
517 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

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

666 (xd_close_bus, Fdbus_init_bus): Handle reference counter properly.
668 2012-07-27 Eli Zaretskii <eliz@gnu.org>
670 * alloc.c (listn): Fix the order the arguments are consed onto the
673 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
674 enumeration constants, as PURE and HEAP are too general, and clash
675 with other headers and sources, such as gmalloc.c and the
676 MS-Windows system headers. All users changed.
678 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
680 Revert last save_excursion_save and save_excursion_restore changes.
681 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

693 Improve GDB symbol export (Bug#12036).
694 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
695 arms of an 'if', not using conditional expressions; otherwise GDB
696 complains about the types in the unevaluated arm when the argument
697 is an integer literal.
698 (xgetint): Simplify expression.
699 * alloc.c (gdb_make_enums_visible): New constant. This ports to
700 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
701 Zaretskii in <http://bugs.gnu.org/12036#13>.
702 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
703 needed now that we have gdb_make_enums_visible.
704 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)

748 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
749 emacs.c, as this is a more-suitable home. Had this been done earlier
750 the fix for 12036 would have avoided some of the problems noted in
751 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
752 would have been more obvious.
753 * emacs.c: Do not include <verify.h>; no longer needed.
754 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
755 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
756 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

762 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
763 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
764 not be usable in #if. This simplifies things.
766 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
768 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
770 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

773 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
774 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
775 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
776 Adjust to changes in lisp.h and emacs.c, by using
777 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
778 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
779 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
780 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
781 instead of gdb_valbits.
782 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
783 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
784 instead of gdb_array_mark_flag.
785 (xboolvector): Get size from $->size, not $->header.size.
786 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
787 (xreload, hook-run, hookpost-run): Remove.
788 * emacs.c: Include <verify.h>.
789 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
790 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
792 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
793 (gdb_USE_LSB_TAG): New enum constants.
794 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
795 Also define these as enum constants, so they're visible to GDB.
796 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
797 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
798 as constants, so they're visible to GDB.
799 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
800 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
801 Now enum constants, not macros, so they're visible to GDB.
802 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
803 more convenient now. All uses changed.
804 (VALMASK) [USE_LSB_TAG]: Also define in this case.

815 add argument, tune behavior, and adjust all callers.
817 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
819 Use typedef for EMACS_INT, EMACS_UINT.
820 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
821 than macros. This simplifies debugging in the usual case, since
822 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
823 and it allows expressions involving EMACS_INT casts.
824 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
826 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
828 * nsterm.m (ns_read_socket): Return early if there is a modal

838 Adjust buffer text indirection counters at the end of Fkill_buffer.
839 * buffer.c (Fkill_buffer): Adjust indirection counters when the
840 buffer is definitely dead. This should really fix an issue reported
841 by Christoph Scholtes again. (Bug#12007).
842 (init_buffer_once): Initialize indirection counters of
843 buffer_defaults and buffer_local_symbols (for sanity and safety).
845 2012-07-24 Eli Zaretskii <eliz@gnu.org>
847 * xdisp.c (init_iterator): Don't compute dimensions of truncation
848 and continuation glyphs on tooltip frames, leave them at zero.
849 Avoids continued lines in tooltips. (Bug#11832)
851 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
853 Simplify copy_overlay.
854 * buffer.c (copy_overlay): Simplify. Use build_marker.

860 or invalid. (Bug#12025)
862 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
863 it signals an error when a tooltip frame is being created.
865 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
867 Cleanup miscellaneous objects allocation and initialization.
868 * alloc.c (allocate_misc): Change to static. Add argument to

876 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
878 Swap buffer text indirection counters in Fbuffer_swap_text.
879 * buffer.c (Fbuffer_swap_text): Swap indirections too.
880 This avoids crash reported by Christoph Scholtes at
881 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
883 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
885 * nsmenu.m (Popdown_data): New struct.
886 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
888 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
889 (initWithContentRect): Make imgView and contentView non-static
890 and autorelease them. Also autorelease img and matrix (Bug#12005).
891 (dealloc): Remove (Bug#12005).
893 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

906 (set_marker_both, set_marker_restricted_both): Use live_buffer.
908 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
910 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
911 as it's limited by the amount of memory, not by INT_MAX.
913 2012-07-21 Eli Zaretskii <eliz@gnu.org>
915 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
916 in special-event-map. See the discussion at
917 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
920 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

1639 * s/aix4-2.h (unix): Remove; no longer needed.
1641 EMACS_TIME simplification (Bug#11875).
1642 This replaces macros (which typically do not work in GDB)

1644 The functional style also makes code easier to read and maintain.
1645 * systime.h: Include <sys/time.h> on all hosts, not just if
1646 WINDOWSNT, since 'struct timeval' is needed in general.

1662 (add_emacs_time, sub_emacs_time): New functions.
1663 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1684 * nsterm.m: Include <ftoastr.h>.
1686 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1687 Prefer snprintf to strncpy.
1688 * nsterm.m (ns_term_init):
1689 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1690 * nsterm.m (ns_term_init):
1691 Avoid the need for strncpy, by using build_string or
1692 make_unibyte_string directly. Use dtoastr, not snprintf.
1693 * process.c (Fmake_network_process): Diagnose service names that
1694 are too long, rather than silently truncating them or creating
1695 non-null-terminated names.
1696 (Fnetwork_interface_info): Likewise, for interface names.
1697 * sysdep.c (system_process_attributes) [GNU_LINUX]:

1712 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1713 where argument type is known to be a Lisp_Cons.

1768 O_RDONLY already includes it).
1770 Stop ns builds setting the EMACSLOADPATH environment variable.
1771 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1772 Now it does not set EMACSLOADPATH, just returns the load-path string.
1773 * nsterm.h: Update accordingly.
1774 * lread.c [HAVE_NS]: Include nsterm.h.
1775 (init_lread) [HAVE_NS]: Use ns_load_path.

1778 2012-07-09 Glenn Morris <rgm@gnu.org>
1780 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,

1785 (ns_init_paths): Do not set EMACSPATH.

1838 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
1839 * nsterm.h (ns_etc_directory): Add it.
1840 * callproc.c [HAVE_NS]: Include nsterm.h.
1841 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1843 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1845 Move marker debugging code under MARKER_DEBUG.
1846 * marker.c (MARKER_DEBUG): Move marker debugging code under
1847 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1848 for bootstrap with --enable-checking (~3x slowdown reported
1849 by Juanma Barranquero <lekktu@gmail.com>).
1850 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1852 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1854 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1855 See <http://bugs.gnu.org/11825#29>.
1857 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1859 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1860 has no font, use the frame's font. (Bug#11813)
1861 (display_line): Add commentary about displaying truncation glyphs
1863 (produce_special_glyphs): Move here from term.c.
1865 * term.c (produce_special_glyphs): Move to xdisp.c.
1867 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1870 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1872 * xdisp.c (display_line): Avoid warning about implicit declaration
1875 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1877 * lisp.h: Remove empty conditional.
1879 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1881 * lread.c (load_path_check): Now static.
1883 Fix some minor --with-ns problems found by static checking.
1884 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1885 (x_set_font) [!HAVE_X_WINDOWS]:
1886 * image.c (xpm_load_image) [HAVE_NS]:
1887 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1888 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1889 Remove unused local.
1890 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1891 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1892 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1893 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1894 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1895 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1896 Fix pointer signedness problem.
1897 * xfaces.c (FRAME_X_FONT_TABLE):
1898 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1900 2012-07-07 Glenn Morris <rgm@gnu.org>
1902 * lread.c (load_path_check): New function, split from init_lread.
1903 (init_lread): Reorganize. Motivation:
1904 If EMACSLOADPATH is set, check/warn about that rather than the
1905 defaults, which we are not going to use. Hence we can remove
1906 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1907 Don't warn if site-lisp directories are missing.
1908 If not installed, start from a blank load-path, since
1909 PATH_LOADSEARCH refers to the eventual installation directories.
1911 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1913 Support truncation and continuation glyphs on GUI frames, when
1914 fringes are disabled. (Bug#11832)
1915 * xdisp.c (init_iterator): Get dimensions of truncation and
1916 continuation glyphs even if on GUI frames. Adjust
1917 it->last_visible_x on GUI frames when the left or right fringes,
1918 or both, are absent.
1919 (start_display, move_it_in_display_line_to): Handle the case of a
1920 GUI frame without a fringe to display continuation or truncation
1922 (insert_left_trunc_glyphs): Support GUI frames: make sure
1923 truncation glyphs overwrite enough glyphs from the current line to
1924 have sufficient space in pixels.
1925 (display_line): Support truncation and continuation glyphs on GUI
1926 frames. If some spare pixels are left on the line after inserting
1927 the truncation glyphs, fill that space with a stretch glyph of a
1928 suitably computed width.
1930 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1931 produce_glyphs, to support GUI sessions.
1933 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1935 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1937 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1939 Do not require float-time's arg to fit in time_t (Bug#11825).
1940 This works better on hosts where time_t is unsigned, and where
1941 float-time is applied to the (negative) difference between two times.
1942 * editfns.c (decode_time_components): Last arg is now double *,
1943 not int *, and means to store all the result as a double, without
1944 worrying about whether the seconds part fits in time_t.
1945 All callers changed.
1946 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1947 All callers changed.
1948 (Ffloat_time): Do not fail merely because the specified time falls
1949 outside of time_t range.
1951 2012-07-07 Glenn Morris <rgm@gnu.org>
1953 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1957 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1959 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1960 Update dependencies.
1962 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1964 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1966 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1967 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1968 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1969 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1970 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1971 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1973 * xfont.c (compare_font_names): Redo to omit the need for casts.
1975 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1977 * xfns.c (Fx_change_window_property): Doc fix.
1978 * w32fns.c (Fx_change_window_property): Doc fix.
1980 * w32fns.c (Fx_window_property): Accept the same arguments as the
1981 X Windows version. Doc fix.
1982 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1984 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1985 Eli Zaretskii <eliz@gnu.org>
1987 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1988 Windows-specific code from nt/config.nt moved here.
1989 Obsolete settings removed.
1991 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1993 * process.c: Avoid unnecessary calls to gettime.
1994 (wait_reading_process_output): Don't get the time of day
1995 when gobbling data immediately and not waiting, as there's no need
1996 for it in that case. This removes a FIXME.
1998 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2000 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2001 is defined (Bug#11768).
2003 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2005 Fix marker debugging code.
2006 * marker.c (byte_char_debug_check): Do not perform the check
2007 if buffer is not multibyte.
2008 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2009 Call byte_char_debug_check with correct arguments.
2011 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2013 Compile marker debugging code only if ENABLE_CHECKING is defined.
2014 * marker.c (byte_char_debug_check, count_markers):
2015 Use only if ENABLE_CHECKING is defined.
2016 (byte_debug_flag): Remove.
2017 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2018 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2020 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2022 Avoid code repetition in marker-related functions.
2023 * marker.c (attach_marker): New function.
2024 (Fset_marker, set_marker_restricted, set_marker_both)
2025 (set_marker_restricted_both): Use it.
2026 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2027 Consistently rename charno to charpos.
2028 (marker_position): Add eassert.
2029 (marker_byte_position): Convert to eassert.
2031 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

2041 * lisp.h (build_marker): New prototype.
2042 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
2043 * composite.c (autocmp_chars): Likewise.
2044 * editfns.c (buildmark): Remove.
2045 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2046 (save_restriction_save): Use build_marker.
2047 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2048 * window.c (save_window_save): Likewise.
2050 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2052 Do not use Fdelete_overlay in delete_all_overlays
2053 to avoid redundant calls to unchain_overlay.
2054 * buffer.c (drop_overlay): New function.
2055 (delete_all_overlays, Fdelete_overlay): Use it.
2056 * minibuf.c (get_minibuffer): Fix comment.
2058 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2060 Port to OpenBSD 5.1 amd64.
2061 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2062 This is needed for OpenBSD, and should be harmless on all BSD systems.
2063 Also, include <sys/sysctl.h>, as it should be available on all
2064 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2065 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2066 use p_pid member, not kp_proc.pid.
2068 2012-07-06 Glenn Morris <rgm@gnu.org>
2070 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2072 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2074 More xmalloc and related cleanup.
2075 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2076 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2079 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2080 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2081 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2082 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2083 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2085 Omit needless casts involving void * pointers and allocation.
2086 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2087 as the former is more robust if P's type is changed.
2088 Prefer xzalloc to xmalloc + memset 0.
2089 Simplify malloc-or-realloc to realloc.
2090 Don't worry about xmalloc returning a null pointer.
2091 Prefer xstrdup to xmalloc + strcpy.
2092 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2094 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2095 alloca of a constant.
2097 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2099 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2100 hscroll is larger than the line width. Fixes long and futile
2101 looping inside extend_face_to_end_of_line (on a TTY) producing
2102 glyphs that are not needed and thrown away.
2104 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2106 * marker.c (set_marker_restricted_both): Simplify by using
2109 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2111 * editfns.c (region_limit): Simplify by using clip_to_bounds.
2113 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
2115 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is

2118 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2119 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2120 followed by gtk_box_set_homogeneous (Bug#11768).
2121 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2122 (update_theme_scrollbar_width, xg_create_scroll_bar):
2123 Use gtk_scrollbar_new (Bug#11768).
2124 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2125 (is_box_type): New function (Bug#11768).
2126 (xg_tool_item_stale_p): Call is_box_type.
2127 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2128 with default display (Bug#11768).
2130 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2132 * xdisp.c (window_hscroll_limited): New function.
2133 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2134 coordinates when window's hscroll is set to insanely large
2137 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2139 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2140 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2142 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2145 * lisp.h (xzalloc): New prototype. Omit needless casts.
2146 * alloc.c (xzalloc): New function. Omit needless casts.
2147 * charset.c: Omit needless casts. Convert all calls to
2148 xmalloc with following memset to xzalloc.

2198 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2200 * fileio.c (time_error_value): Check the right error number.
2201 Problem reported by Troels Nielsen in
2202 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2204 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2206 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2207 This should be fixed in a better way; see Eli Zaretskii in
2208 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2209 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2211 * fileio.c (time_error_value): Rename from special_mtime.
2212 The old name's problems were noted by Eli Zaretskii in
2213 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2215 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2216 This variable's comment says Emacs needs at least one GDB-visible
2217 symbol of type enum pvec_type, to work around GDB problems.
2218 The symbol's value doesn't matter.
2220 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2221 that causes compilation to fail on pre-C99 compilers.
2223 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2225 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2226 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2228 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2230 * buffer.c (init_buffer_once): Fix initialization of
2231 headers for buffer_defaults and buffer_local_symbols.
2232 Reported by Juanma Barranquero <lekktu@gmail.com>.
2234 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2236 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2237 * lisp.h (enum pvec_type): Use fewer bits.
2238 (PSEUDOVECTOR_SIZE_BITS): New constant.
2239 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2240 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2241 change in pvec_type.
2242 (PSEUDOVECTOR_TYPEP): New macro.
2243 (TYPED_PSEUDOVECTORP): Use it.
2244 * fns.c (internal_equal): Adapt code to extract pvectype.
2245 * emacs.c (gdb_pvec_type): Update type.
2246 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2247 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2248 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2249 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2250 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2251 abusing vector->header.next.nbytes.
2252 (live_vector_p): Use PVEC_TYPE.
2253 (mark_object): Adapt code to extract pvectype. Use switch.
2255 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2257 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2258 Tighten new eassert a bit.
2260 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2262 Fix compilation with --enable-gcc-warnings and -O1
2264 * doprnt.c (doprnt): Change type of tem to int, initialize
2265 to avoid compiler warning. Add eassert.
2266 * search.c (simple_search): Initialize match_byte to avoid
2267 compiler warning. Add eassert.
2269 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2271 Avoid weird behavior with large horizontal scrolls.
2272 Without this change, for example, large hscroll values would
2273 mess up Emacs's display on Fedora 15 x86, presumably due to
2274 overflows in int calculations in the display code.
2275 Also, if buffers had long lines, Emacs would freeze.
2276 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2277 (set_window_hscroll): New function, containing the old guts of
2278 Fset_window_hscroll. Return the clipped value.
2279 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2280 This avoids the need to check against PTRDIFF_MAX.
2282 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2284 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2286 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2288 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2290 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2291 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2292 since GCC 4.4.6 issues a bogus warning for them.
2294 Fix bugs in file timestamp newness comparisons.
2295 * fileio.c (Ffile_newer_than_file_p):
2296 * lread.c (Fload): Use full timestamp resolution of files,
2297 not just the 1-second resolution, so that files that are only
2298 slightly newer still count as newer.
2299 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2300 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2302 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2304 * fileio.c: Improve handling of file time marker. (Bug#11852)
2305 (special_mtime): New function.
2306 (Finsert_file_contents, Fverify_visited_file_modtime):
2307 Use it to set special mtime values consistently.
2309 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2311 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2312 marker for non-existing file. (Bug#11852)
2314 2012-07-03 Glenn Morris <rgm@gnu.org>
2316 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2317 and did not make it into globals.h).
2319 2012-07-03 Tom Tromey <tromey@redhat.com>
2321 * window.c (Fset_window_margins, Fset_window_fringes)
2322 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2323 * textprop.c (Fprevious_property_change): No longer static.

2340 * composite.c (Fcomposition_get_gstring): No longer static.
2341 * callproc.c (Fgetenv_internal): No longer static.

2347 * fontset.h: Remove EXFUN.
2348 * font.h: Remove EXFUNs.
2349 * dosfns.c (system_process_attributes): Remove EXFUN.
2350 * keymap.h: Remove EXFUNs.

2352 * w32term.h: Remove EXFUNs.
2353 * window.h: Remove EXFUNs.

2357 2012-07-03 Glenn Morris <rgm@gnu.org>
2359 * lisp.h (Frandom): Make it visible to C.
2360 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2361 buffer for invisible buffers. (Bug#1229)
2363 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2365 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2366 values which aren't power of 2.
2367 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2368 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2371 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2373 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2375 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2377 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2379 * alloc.c (allocate_vector_block): Remove redundant
2380 calls to mallopt if DOUG_LEA_MALLOC is defined.
2381 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2382 avoid calls to mallopt if zero_vector is returned.
2384 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2386 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2387 is enabled, avoid dereferencing NULL current_sblock if
2390 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2392 Cleanup basic buffer management.
2393 * buffer.h (struct buffer): Change layout to use generic vector
2394 marking code. Fix some comments. Change type of 'clip_changed'
2395 to bitfield. Remove unused #ifndef old.
2396 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2397 (GET_OVERLAYS_AT): Fix indentation.
2398 (for_each_per_buffer_object_at): New macro.
2399 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2400 (Fbuffer_local_variables): Use it.
2401 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2402 * alloc.c (allocate_buffer): Adjust to match new layout of
2403 struct buffer. Fix comment.
2404 (mark_overlay): New function.
2405 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2406 Lisp area of struct buffer.
2407 (mark_object): Use it. Adjust marking of misc objects
2408 and related comments.
2410 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2412 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2413 wrapper that is not needed because the wrapped code is a no-op (zero
2414 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2415 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2417 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2419 * alloc.c (mark_buffer): Simplify. Remove prototype.
2420 (mark_object): Add comment. Reorganize marking of vector-like
2421 objects. Use CHECK_LIVE for all vector-like objects except buffers
2422 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2423 redundant calls to mark_vectorlike for bool vectors.
2425 2012-06-30 Glenn Morris <rgm@gnu.org>
2427 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2429 * epaths.in (PATH_SITELOADSEARCH): New.
2430 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2431 This is rather than relying on --enable-locallisppath elements
2432 having "site-lisp" in their names. (Bug#10208#25, 11658)
2434 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2436 * w32proc.c (sys_select): Accept and ignore one more argument.
2438 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2440 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2441 (pselect) [!MS_DOS]: Redirect to sys_select.
2443 * sysdep.c: Don't include dos.h and dosfns.h.
2445 * process.c (sys_select):
2446 * msdos.c (sys_select): Accept one more argument and ignore it.
2448 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2449 adapt data types and code to that.
2452 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2453 which clashes with the gnulib function of the same name.
2455 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2457 * font.c (font_style_to_value, font_style_symbolic)
2458 (font_prop_validate_style): Add type checks for values in
2461 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2463 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2466 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2468 * xdisp.c (try_window_id): Undo last change.
2470 * w32.c (getwd): Adjust commentary about startup_dir.
2471 (init_environment): Always call sys_access, even in non-MSVC
2472 builds. Don't chdir to the directory of the Emacs executable.
2473 This undoes code from 1997 which was justified by the need to
2474 "avoid conflicts when removing and renaming directories". But its
2475 downside was that every relative file name was being interpreted
2476 relative to the directory of the Emacs executable, which can never
2477 be TRT. In particular, it broke sys_access when called with
2478 relative file names.
2479 (sys_access): Map GetLastError to errno.
2481 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2483 * window.h (struct window): Change type of 'fringes_outside_margins'
2484 to bitfield. Fix comment. Adjust users accordingly.
2485 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2487 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2490 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2492 * gnutls.c (emacs_gnutls_handshake):
2493 Add QUIT to make the loop interruptible.
2495 2012-06-29 Glenn Morris <rgm@gnu.org>
2497 * charset.c (init_charset): Make lack of etc/charsets fatal.
2499 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2501 * editfns.c (region_limit): Fix type mismatch.
2503 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2505 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2506 undefined. Convert from xassert to eassert.
2507 * nsmenu.m: Convert from xassert to eassert.
2508 * nsterm.m: Likewise.
2510 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2512 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2514 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2516 Avoid integer overflow on scroll-left and scroll-right.
2517 * window.c (HSCROLL_MAX): New macro.
2518 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2519 overflow when requested scroll falls outside ptrdiff_t range.
2521 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2523 * window.h (struct window): Change type of 'hscroll',
2524 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2525 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2526 Adjust users accordingly.
2527 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2528 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2529 from EMACS_INT to ptrdiff_t.
2530 (make_window): Omit redundant initialization.
2532 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2536 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2538 * window.h (struct window): Change type of 'use_time' and
2539 'sequence_number' from Lisp_Object to int.

2605 * alloc.c (allocate_string): Omit intervals initialization.
2606 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2607 as in make_pure_string and make_pure_c_string.
2609 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2611 * alloc.c (allocate_string): Fix last change.
2613 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2665 a better opportunity to optimize away calls to strlen when the
2666 function is called with compile-time constant argument.
2667 * image.c (imagemagick_error): Convert to build_string.
2668 * w32proc.c (sys_spawnve): Likewise.
2669 * xterm.c (x_term_init): Likewise.
2671 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2673 Use sprintf return value instead of invoking strlen on result.
2674 In the old days this wasn't portable, since some sprintf
2675 implementations returned char *. But they died out years ago and
2676 Emacs already assumes sprintf returns int.
2677 Similarly for float_to_string.
2678 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2679 * ccl.c (ccl_driver):
2680 * character.c (string_escape_byte8):

2683 * print.c (print_object):
2684 * xdisp.c (message_dolog):
2685 * xfns.c (syms_of_xfns):
2686 Use sprintf or float_to_string result to avoid need to call strlen.
2687 * data.c (Fnumber_to_string):
2688 Use make_unibyte_string, since the string must be ASCII.
2689 * lisp.h, print.c (float_to_string): Now returns int length.
2690 * term.c (produce_glyphless_glyph):
2691 Use sprintf result rather than recomputing it.
2693 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2694 * Makefile.in (ALL_CFLAGS):
2695 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2724 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2726 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2731 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2732 instead of truncating it to 63 (admittedly a generous limit).
2734 * process.c: Fix spelling and caps in comments.
2736 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2738 * emacs.c (setpgrp): Remove definition, unused.

2750 * systime.h [WINDOWSNT]: Include sys/time.h.
2752 * s/ms-w32.h (struct timespec): Definition moved from
2753 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
2755 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

2820 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2822 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2824 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in

2828 language ID in the event parameters.
2830 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2860 Don't assume EMACS_TIME and struct timeval are the same type.
2862 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2864 Support higher-resolution time stamps (Bug#9000).
2865 The time stamps are only nanosecond-resolution at the C level,
2866 since that's the best that any real-world system supports now.
2867 But they are picosecond-resolution at the Lisp level, as that's
2868 easy, and leaves room for future OS improvements.
2870 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2873 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2874 Don't get current time unless it's needed.
2876 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2877 now provides it if it's absent.
2878 (start_atimer): Port to higher-res time stamps.
2879 Check for time stamp overflow. Don't get current time more
2880 often than is needed.
2882 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2883 Include systime.h, not time.h.
2884 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2886 * dired.c: Include stat-time.h.
2887 (Ffile-attributes): File times now have higher resolution.
2889 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2890 (struct image): Timestamp now has higher resolution.
2892 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2893 has at least microseconds now. All uses removed.
2894 (update_frame, update_single_window, update_window, update_frame_1)
2895 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2897 * editfns.c (time_overflow): Now extern.
2898 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2899 (float-time, Fformat_time_string, Fcurrent_time_string)
2900 (Fcurrent_time_zone): Accept and generate higher-resolution

2904 (make_time): Now static.
2905 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2906 Report an error if the time is invalid, rather than having the caller
2909 * fileio.c: Include <stat-time.h>
2910 (Fcopy_file): Copy higher-resolution time stamps.
2911 Prefer to set the time stamp via a file descriptor if that works.

2913 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2914 (Fvisited_file_modtime, Fset_visited_file_modtime):
2915 Support higher-resolution time stamps.
2917 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2919 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2921 * image.c (prepare_image_for_display, clear_image_cache)
2922 (lookup_image): Port to higer-resolution time stamps.
2924 * keyboard.c (start_polling, bind_polling_period):
2925 Check for time stamp overflow.
2926 (read_char, kbd_buffer_get_event, timer_start_idle)
2927 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2928 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2929 Port to higher-resolution time stamps. Do not assume time_t is signed.
2930 (decode_timer): New function. Timers are now vectors of length 9,
2931 not 8, to accommodate the picosecond component.
2932 (timer_check_2): Use it.
2934 * nsterm.m (select_timeout, timeval_subtract): Remove.
2935 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2936 as they're a bit more accurate and handle overflow better.
2937 (ns_select): Change prototype to be compatible with pselect.
2938 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2939 * nsterm.h (ns_select): Adjust prototype.
2941 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2942 us-resolution time stamps.
2943 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2945 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2947 * lisp.h (time_overflow): New decl.
2948 (wait_reading_process_output): First arg is now intmax_t, not int,
2949 to accommodate larger waits.
2951 * process.h (struct Lisp_Process.read_output_delay):
2952 Now counts nanoseconds, not microseconds.
2953 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2955 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2956 (wait_reading_process_output):
2957 Port to ns-resolution time stamps.
2958 (Faccept_process_output, wait_reading_process_output):
2959 Check for time stamp overflow. Do not assume time_t is signed.
2960 (select_wrapper): Remove; we now use pselect.
2961 (Fprocess_attributes): Now generates ns-resolution time stamps.
2963 * sysdep.c: Include utimens.h. Don't include utime.h
2964 or worry about struct utimbuf; gnulib does that for us now.
2965 (gettimeofday): Remove; gnulib provides a substitute.
2966 (make_timeval): New function.
2967 (set_file_times): Now sets ns-resolution time stamps.
2968 New arg FD; all uses changed.
2969 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2970 (system_process_attributes):
2971 Now returns ns-resolution time stamp. All uses changed.
2972 Check for time stamp overflow.
2974 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2975 provides a substitute now.
2977 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2978 since it guarantees struct timespec.
2979 (EMACS_TIME): Now struct timespec, so that we can support
2980 ns-resolution time stamps.
2981 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2982 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2983 (EMACS_USECS): Remove.
2984 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2985 so multiply the arg by 1000 before storing it.
2986 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2988 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2989 Port to ns-resolution time stamps.
2990 (EMACS_TIME_NEG_P): Remove; replaced by....
2991 (EMACS_TIME_SIGN): New macro.
2992 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2993 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2994 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2995 (make_timeval, make_lisp_time, decode_time_components): New decls.
2996 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2997 that it mishandled time_t overflow. You can't compare by subtracting!
2998 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2999 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3001 * term.c: Include <sys/time.h>.

3007 (Fprimitive_undo): Use them when restoring time stamps.
3009 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3010 (w32_get_internal_run_time):
3011 Port to higher-resolution Emacs time stamps.
3012 (ltime): Now accepts single 64-bit integer, as that's more convenient
3015 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3017 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3018 for compatibility with pselect. Support ns-resolution time stamps.
3020 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3022 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3023 Check for time stamp overflow, and support ns-resolution time stamps.
3025 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3026 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3027 (timeval_subtract): Remove; no longer needed.
3028 (XTflash, XTring_bell, x_wait_for_event):
3029 Port to ns-resolution time stamps. Don't assume time_t is signed.
3031 2012-06-22 Chong Yidong <cyd@gnu.org>

3035 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3037 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3038 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3039 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3040 staticidx goes up to 1597 out of 1600 = 0x640.)
3042 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3044 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3045 Otherwise, the umask might be mistakenly 0 while handling input signals.

3067 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3069 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

3078 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3079 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3080 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3081 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3082 (METER_1, METER_2): Simplify.
3084 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

3088 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3090 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3091 gets killed during executing of this function (Bug#11665).
3092 Try to always return Qt when the buffer has been actually killed.
3093 (Vkill_buffer_query_functions): In doc-string say that functions
3094 run by this hook should not change the current buffer.
3096 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3098 Fix recently-introduced process.c problems found by static checking.

3116 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3118 * lisp.h (eassert): Assume C89 or later.
3119 This removes the need for CHECK.
3120 (CHECK): Remove. Its comments about always evaluating its
3121 argument were confusing, as 'eassert' typically does not evaluate
3124 * coding.c (produce_chars): Use ptrdiff_t, not int.
3126 * xterm.c (x_draw_underwave): Check for integer overflow.
3127 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3220 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
3221 If all the glyphs of the glyph row came from strings, and we have no
3222 cursor positioning clues, put the cursor on the first glyph of the

3266 * s/usg5-4-common.h (USG5_4): No longer define; unused.
3268 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
3270 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
3273 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
3275 * emacs.c (gdb_use_struct): Rename from gdb_use_union.
3276 * .gdbinit: Check gdb_use_struct instead of gdb_use_union.
3277 * alloc.c (widen_to_Lisp_Object): Remove.

3279 * frame.c (delete_frame): Remove outdated comment.
3280 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
3281 USE_LISP_UNION_TYPE.

3283 (Fw32_toggle_lock_key): Likewise.
3284 * w32menu.c (add_menu_item): Likewise.
3285 (w32_menu_display_help): Use XIL instead of checking

3298 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
3300 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
3301 * alloc.c (make_number) [!defined make_number]:
3302 Remove, as lisp.h always defines this now.
3303 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
3304 (roundup_size): Verify that it is a power of 2.
3305 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
3306 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
3307 * lisp.h (USE_LSB_TAG): Allow the builder to compile with

3309 USE_LSB_TAG now is always defined to be either 0 or 1.
3311 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3312 code works fine either way, and efficiency is not a concern here,
3313 as the union type is for debugging, not for production.
3314 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3315 Use an inline function on all platforms when using the union type,
3316 since this is simpler and 'static inline' can be used portably
3318 (LISP_INITIALLY_ZERO): New macro.
3319 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3320 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3347 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
3348 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
3349 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

3389 dbus_type_is_basic if available.
3390 (xd_extract_signed, xd_extract_unsigned): Rename from
3391 extract_signed and extract_unsigned, respectively. Adapt callers.
3393 2012-06-09 Chong Yidong <cyd@gnu.org>

3402 * xdisp.c (vmessage): Treat frame message as multibyte.
3403 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
3404 would generate the diagnostic "Making \302\247 buffer-local while
3407 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3409 * dispnew.c (showing_window_margins_p): Undo last change, which

3423 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3425 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3427 * alloc.c (allocate_vectorlike): Fix last change.
3429 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
3431 Block-based vector allocation of small vectors.
3432 * lisp.h (struct vectorlike_header): New field `nbytes',
3433 adjust comment accordingly.
3434 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
3435 to denote vector blocks. Adjust users (live_vector_p,
3436 mark_maybe_pointer, valid_lisp_object_p) accordingly.

3451 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
3452 (init_alloc_once): Add call to init_vectors.

3456 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
3458 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3460 * doprnt.c (doprnt): Truncate multibyte char correctly.
3461 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3462 would mishandle a string argument "Xc" if X was a multibyte
3463 character of length 2: it would truncate after X's first byte
3464 rather than including all of X.
3466 2012-06-06 Chong Yidong <cyd@gnu.org>
3468 * buffer.c (word_wrap): Doc fix.
3470 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

3517 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3518 Convert pctcpu and pctmem to Lisp float properly.
3519 Let the compiler fold better, as 100.0/0x8000 is exact.
3521 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3523 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3526 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3528 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3530 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3532 For a 'struct window', replace some Lisp_Object fields to
3533 bitfields where appropriate, remove unused fields.
3534 * window.h (struct window): Remove unused 'last_mark_x' and
3535 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3536 change it's type from Lisp_Object to bitfield.
3537 Change type of 'force_start', 'optional_new_start',
3538 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3539 fields from Lisp_Object to bitfield. Adjust users accordingly.
3541 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3543 Pacify gcc -Wdouble-precision when using Xaw.
3544 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3545 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3546 Use 'float' consistently, rather than 'float' in most places
3547 and 'double' in a couple of places.
3549 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3551 * xdisp.c (handle_stop): Detect whether we have overlay strings
3552 loaded by testing it->current.overlay_string_index to be
3553 non-negative, instead of checking whether n_overlay_strings is
3554 positive. (Bug#11587)
3556 2012-05-31 Chong Yidong <cyd@gnu.org>
3558 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3560 * doc.c (Fsubstitute_command_keys): Doc fix.
3562 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3564 * search.c (search_buffer): Remove calls to
3565 r_alloc_inhibit_buffer_relocation, as it is now called by
3566 maybe_unify_char, which was the cause of relocation of buffer text
3569 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3571 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3572 for the duration of call to load_charset, to avoid problems with
3573 callers of maybe_unify_char that access buffer text through C
3576 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3577 decrement the inhibition flag, instead of just setting or
3580 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3582 Remove obsolete '#define static' cruft.
3583 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3584 This #undef was "temporary" in 2000; it is no longer needed
3585 now that '#define static' has gone away.
3586 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3587 (gray_bitmap_bits): Remove; no longer needed.
3588 All uses replaced with definiens.
3589 * xterm.c: Include "bitmaps/gray.xbm".
3591 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3593 Clean up __executable_start, monstartup when --enable-profiling.
3594 The following changes affect the code only when profiling.
3595 * dispnew.c (__executable_start): Rename from safe_bcopy.
3596 Define only on platforms that need it.
3597 * emacs.c: Include <sys/gmon.h> when profiling.
3598 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3599 (__executable_start): Remove decl, since lisp.h does it now.
3600 (safe_bcopy): Remove decl; no longer has that name.
3601 (main): Coalesce #if into single bit of code, for simplicity.
3602 Cast pointers to uintptr_t, since standard libraries want integers

3627 * lread.c (read1): Tiny simplification.
3629 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3631 Do not create empty overlays with the evaporate property (Bug#9642).
3632 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3633 Bug#9642, but explicitly check that the buffer the overlay would
3634 be moved to is live and rearrange lines to make sure that errors
3635 will not put the overlay in an inconsistent state.
3636 (Fdelete_overlay): Cosmetics.
3638 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3640 * w32term.c (my_bring_window_to_top): New function.
3641 (x_raise_frame): Use handle returned by DeferWindowPos, which

3646 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3647 by calling BringWindowToTop.

3652 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3654 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3655 This avoids undefined behavior that might cause the eassert
3656 to not catch an out-of-range value.
3658 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3660 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3672 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3674 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3675 Only r_alloc_inhibit_buffer_relocation needed to be added;
3676 the others were already declared.
3678 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3679 before checking whether it's out of range. Put the check inside
3681 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3683 2012-05-27 Ken Brown <kbrown@cornell.edu>
3685 * callproc.c (Fcall_process): Restore a line that was accidentally
3686 commented out in the 2011-02-13 change (bug#11547).

3690 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3691 defined on ralloc.c.
3693 * buffer.c [REL_ALLOC]: Remove prototypes of
3694 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3695 they are now on lisp.h.
3697 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3699 * search.c (search_buffer): Use it to inhibit relocation of buffer
3700 text while re_search_2 is doing its job, because re_search_2 is
3701 passed C pointers to buffer text. (Bug#11519)
3703 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3706 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3707 state after an additional call to move_it_in_display_line_to, keep
3708 the values of it->max_ascent and it->max_descent found for the
3710 (pos_visible_p): Revert the comparison against bottom_y to what it
3711 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3714 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3716 Fix coding-related core dumps with gcc -ftrapv.
3717 The code was computing A - B, where A and B are pointers, and B is
3718 random garbage. This can lead to core dumps on platforms that
3719 have special pointer registers, and it also leads to core dumps on
3720 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3721 A - B only when B is initialized properly.
3722 * coding.c (coding_set_source, coding_set_destination): Return void.
3723 (coding_change_source, coding_change_destinations): New functions,
3724 with the old behaviors of coding_set_source and coding_set_destination.
3725 All callers that need an offset changed to use these new functions.
3727 2012-05-26 Glenn Morris <rgm@gnu.org>
3729 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3731 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3733 Extend mouse support on W32 text-mode console.

3744 moves, call note_mouse_highlight. If help_echo changed, call
3745 gen_help_event to produce help-echo message in the echo area.
3746 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3749 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3751 * lread.c (read1): Simplify slightly to avoid an overflow warning
3752 with GCC 4.7.0 on x86-64.
3754 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3756 * bidi.c (bidi_mirror_char): Revert last change: an int is
3757 definitely wide enough here.
3759 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3761 Fix integer width and related bugs (Bug#9874).

3773 Use int, not EMACS_INT, where int is wide enough.

3793 (Foverlay_recenter, last_overlay_modification_hooks_used)
3794 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3795 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3796 (validate_region): Omit unnecessary test for b <= e,
3797 since that's guaranteed by the previous test.
3798 (adjust_overlays_for_delete): Avoid pos + length overflow.
3799 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3800 (report_overlay_modification):
3801 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3802 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3811 not int, to avoid needless 32-bit limit on 64-bit hosts.
3812 (exec_byte_code): Use tighter memory-full test, one that checks
3813 for alloca overflow. Don't compute the address of the object just
3814 before an array, as that's not portable. Use EMACS_INT, not
3815 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3816 * callint.c (Fcall_interactively):
3817 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3829 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3830 (casify_object): Avoid integer overflow when overallocating buffer.
3831 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3834 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3835 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3836 integers are now checked earlier. All uses replaced with XINT.
3838 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3839 For CCL_MapSingle, check that content and value are in int range.
3840 (ccl_driver, Fregister_code_conversion_map):
3841 Check that Vcode_version_map_vector is a vector.
3842 (resolve_symbol_ccl_program): Check that vector header is in range.
3843 Always copy the vector, so that we can check its contents reliably
3844 now rather than having to recheck each instruction as it's being
3845 executed. Check that vector words fit in 'int'.
3846 (ccl_get_compiled_code, Fregister_ccl_program)
3847 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3848 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3849 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3850 contents are in range.
3851 (Fccl_execute_on_string): Check that status is in range.
3852 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3853 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3854 Accept and return EMACS_INT, not int, because callers can pass values

3860 (string_escape_byte8, Fget_byte):
3861 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3863 avoid mishandling large integers.
3864 * character.h: Adjust decls to match defn changes elsewhere.

3874 Don't rely on undefined behavior with signed left shift overflow.
3875 Don't assume unsigned int fits into fixnum, or that fixnum fits
3876 into unsigned int. Don't require max_code to be a valid fixnum;
3877 that's not true for gb10830 4-byte on a 32-bit host. Allow
3878 invalid_code to be a cons, for the same reason. Require code_offset
3879 to be a character. Avoid int overflow if max_char is close
3881 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3882 this is intended anyway and avoids some undefined behavior.
3883 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3884 INDEX_TO_CODE_POINT, as that's what it expects.
3885 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3886 * charset.h (DECODE_CHAR): Return int, not unsigned;
3887 this is what was intended anyway, and it avoids undefined behavior.
3888 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3889 integer-overflow issues.
3890 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3891 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3892 where the argument is EMACS_INT, and this behavior is not intended.
3893 * chartab.c (Fmake_char_table, Fset_char_table_range)
3894 (uniprop_get_decoder, uniprop_get_encoder):
3895 Don't assume fixnum fits in int.
3896 * cmds.c (move_point): New function, that does the gist of
3897 Fforward_char and Fbackward_char, but does so while checking
3898 for integer overflow more accurately.
3899 (Fforward_char, Fbackward_char): Use it.
3900 (Fforward_line, Fend_of_line, internal_self_insert)
3901 (internal_self_insert):
3902 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4681 * lread.c (init_obarray): Declare Qt and Qnil as special.
4683 2012-05-14 Glenn Morris <rgm@gnu.org>
4685 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4686 Put "libexec" before "bin", for the sake of init_callproc_1.
4688 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4690 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4692 * unexaix.c: Port to more-recent AIX compilers.
4693 (report_error, report_error_1, make_hdr, copy_sym)
4694 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4695 Make arguments const char *, not char *, to avoid violations of C
4696 standard and to fix some AIX warnings reported by Gilles Pion.
4698 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4700 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4701 already have overlays loaded.
4702 (handle_single_display_spec): Before returning without displaying
4703 fringe bitmap, synchronize the bidi iterator with the main display
4704 iterator, by calling iterate_out_of_display_property.
4705 (iterate_out_of_display_property): Detect buffer iteration by
4706 testing that it->string is a Lisp string.
4707 (get_next_display_element): When the current object is exhausted,
4708 and there's something on it->stack, call set_iterator_to_next to
4709 proceed with what's on the stack, instead of returning zero.
4710 (set_iterator_to_next): If called at the end of a Lisp string,
4711 proceed to consider_string_end without incrementing string
4712 position. Don't increment display vector index past the end of
4713 the display vector. (Bug#11417)
4714 (pos_visible_p): Don't report a position visible when move_it_to
4715 stopped at the last line of window, which happens to be scanned
4716 backwards by the bidi iteration. (Bug#11464)
4718 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4720 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4721 and right-margin display specs even if the spec is invalid or we
4722 are on a TTY, and thus unable to display on the fringes.
4723 That's because the text with the property will not be displayed anyway,
4724 so we need to signal to the caller that this is a "replacing"
4725 display spec. This fixes display when the spec is invalid or we
4728 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4730 * unexaix.c (make_hdr): Fix typo in prototype.
4731 This bug broke the build on AIX. Problem reported by Gilles Pion.
4733 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4735 * keyboard.c (kbd_buffer_get_event): Read special events also in
4736 batch mode. (Bug#11415)
4738 2012-05-12 Glenn Morris <rgm@gnu.org>
4740 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4742 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4744 * lisp.mk (lisp): Add newcomment.elc.
4746 2012-05-12 Glenn Morris <rgm@gnu.org>
4748 * Makefile.in (MKDIR_P): New, set by configure.
4749 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4751 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4753 Remove unused function hourglass_started.
4754 * dispextern.h (hourglass_started):
4755 * w32fns.c (hourglass_started):
4756 * xdisp.c (hourglass_started): Remove.
4758 2012-05-10 Juanma Barranquero <lekktu@gmail.com>

4761 Update dependencies.
4763 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4765 * xgselect.c (xg_select): Put maxfds+1 into a var.
4766 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4768 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4770 2012-05-10 Dave Abrahams <dave@boostpro.com>
4772 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4773 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4775 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4777 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4778 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4779 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4780 Initialize xd_registered_buses.
4782 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4784 Untag more efficiently if USE_LSB_TAG.
4785 This is based on a proposal by YAMAMOTO Mitsuharu in
4786 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4787 For an admittedly artificial (nth 8000 longlist) benchmark on
4788 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4789 Emacs's overall text size by 1%.
4790 * lisp.h (XUNTAG): New macro.
4791 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4792 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4793 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4794 * eval.c (Fautoload):
4795 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4796 * frame.h (XFRAME): Use XUNTAG.
4798 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4799 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4800 Remove unportable assumptions about print widths of types like
4802 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4803 intptr_t when converting between pointer and integer, to avoid GCC
4804 warnings about wrong width.
4806 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4808 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4809 stack for each reader_thread, instead of defaulting to 8MB
4810 determined by the linker. This avoids failures in creating
4811 subprocesses on Windows 7, see the discussion in this thread:
4812 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4814 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4816 Fix up display of the *Minibuf-0* buffer in the mini window.
4817 * keyboard.c (read_char): Don't clear the echo area if there's no
4819 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4820 contents of *Minibuf-0*) if there's no message displayed in its stead.
4822 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4824 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4827 2012-05-06 Chong Yidong <cyd@gnu.org>
4829 * lisp.mk (lisp): Update.
4831 2012-05-05 Jim Meyering <meyering@redhat.com>
4833 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4835 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4837 * data.c (PUT_ERROR): New macro.
4838 (syms_of_data): Use it. Add new error type `user-error'.
4839 * undo.c (user_error): New function.
4840 (Fprimitive_undo): Use it.
4841 * print.c (print_error_message): Adjust print style for `user-error'.
4842 * keyboard.c (user_error): New function.
4843 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4845 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4847 Do not limit current-time-string to years 1000..9999.
4848 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4849 (Fcurrent_time_string): Support any year that is supported by the
4850 underlying localtime representation. Don't use asctime, as it
4851 has undefined behavior for years outside the range -999..9999.
4853 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4855 Fix race conditions involving setenv, gmtime, localtime, asctime.
4856 Without this fix, interrupts could mess up code that uses these
4857 nonreentrant functions, since setting TZ invalidates existing
4858 tm_zone or tzname values, and since most of these functions return
4859 pointers to static storage.
4860 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4861 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4862 Grow the critical sections to include not just invoking
4863 localtime/gmtime, but also accessing these functions' results
4864 including their tm_zone values if any, and any related TZ setting.
4865 (format_time_string): Last arg is now struct tm *, not struct tm **,
4866 so that the struct tm is saved in the critical section.
4867 All callers changed. Simplify allocation of initial buffer, partly
4868 motivated by the fact that memory allocation needs to be outside
4869 the critical section.
4871 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4873 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4874 with RESET_INTERVAL.

4885 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4887 * xdisp.c (pos_visible_p): If already at a newline from the
4888 display string before the 'while' loop, don't walk back the glyphs
4889 from it3.glyph_row. Solves assertion violation when the display
4890 string begins with a newline (egg.el). (Bug#11367)
4892 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4894 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4897 2012-05-01 Glenn Morris <rgm@gnu.org>
4899 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4900 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4901 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4902 All were removed before 23.1.
4904 * dispnew.c: Remove HAVE_LIBNCURSES test;
4905 it is always true on relevant platforms.
4907 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4908 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4910 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4912 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4914 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4915 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4918 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4920 Do not avoid creating empty evaporating overlays (Bug#9642).
4921 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4922 That is, do not delete an evaporating overlay if it becomes
4923 empty after its bounds are adjusted to fit within its buffer.
4924 This fix caused other problems, and I'm reverting it until we get
4925 to the bottom of them.
4927 2012-04-27 Chong Yidong <cyd@gnu.org>
4929 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4931 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4933 * xdisp.c (pos_visible_p): If the window start position is beyond
4934 ZV, start the display from buffer beginning. Prevents assertion
4935 violation in init_iterator when the minibuffer window is scrolled
4938 * window.c (window_scroll_pixel_based): Likewise.
4940 2012-04-27 Chong Yidong <cyd@gnu.org>
4942 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4944 2012-04-27 Glenn Morris <rgm@gnu.org>

4947 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4949 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4951 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4952 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4954 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4956 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4957 display element, check also the underlying string or buffer
4958 character. (Bug#11341)
4960 * w32menu.c: Include w32heap.h.
4961 (add_menu_item): If the call to AppendMenuW (via
4962 unicode_append_menu) fails, disable Unicode menus only if we are
4963 running on Windows 9X/Me.
4965 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4967 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4970 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4972 * keyboard.c (read_char): Don't wipe echo area for select window
4973 events: These might get delayed via `mouse-autoselect-window'
4976 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4978 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4979 manipulation of :loaded-from data.
4981 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4983 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4984 now a cons (bug#11311).
4986 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4988 Do not create empty overlays with the evaporate property (Bug#9642).
4989 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4990 if it becomes empty after its bounds are adjusted to fit within
4991 its buffer. Without this fix, in a nonempty buffer (let ((o
4992 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4993 yields an empty overlay that has the evaporate property, which is
4994 not supposed to happen.
4996 Fix minor GTK3 problems found by static checking.
4997 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4998 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4999 (struct _EmacsFixedClass, emacs_fixed_get_type):

5012 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5014 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5016 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5017 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5018 (__malloc_size_t, __malloc_ptrdiff_t):
5019 Remove. All uses removed, replaced by the definiens if needed,
5020 since we can assume C89 or better now.

5030 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5031 Define using prototypes, not old style.
5032 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5033 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5034 (align): Don't assume that signed integer overflow wraps around.
5035 Omit unused local var.
5036 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

5111 * sysdep.c [__FreeBSD__]: Minor cleanups.
5112 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5113 Use Emacs indenting style more consistently. Avoid some casts.
5114 Use 'double' consistently rather than mixing 'float' and 'double'.
5116 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5118 * sysdep.c (list_system_processes, system_process_attributes):

5134 (print_object): Check for cycles even when print-circle is nil and
5135 print-gensym is t, but only check print_depth if print-circle is nil.
5137 2012-04-20 Chong Yidong <cyd@gnu.org>
5139 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5140 set the status to "failed" and ensure that sentinel is run.

5197 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5198 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

5200 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5201 Remove one incorrect comment and fix another.

5215 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5216 Remove decls. This fixes an "It stinks!".
5218 * alloc.c (which_symbols): Fix alignment issue / type clash.
5220 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5222 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5268 2012-04-11 Daniel Colascione <dancol@dancol.org>
5270 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5271 against is gone. It's better to use vfork now so that when Cygwin
5272 gains a new, working vfork, we use it automatically (bug#10398).
5274 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5312 Add convenience `GNUTLS_LOG2i' macro.
5314 * gnutls.c (gnutls_log_function2i): Convenience log function.
5315 (emacs_gnutls_read): Use new log functions,
5316 `gnutls_handshakes_tried' process member, and
5317 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5318 attempts per process (connection).
5320 2012-04-09 Chong Yidong <cyd@gnu.org>
5322 * eval.c (Fuser_variable_p, user_variable_p_eh)

5327 * minibuf.c (Fread_variable): Callers changed.
5329 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5331 * xdisp.c (set_cursor_from_row): If the display string appears in
5332 the buffer at position that is closer to point than the position
5333 after the display string, display the cursor on the first glyph of
5334 the display string. Fixes cursor display when a 'display' text
5335 property immediately follows invisible text. (Bug#11094)
5337 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5339 composite.c: use 'double' consistently
5340 * composite.c (get_composition_id): Use 'double' consistently
5341 instead of converting 'float' to 'double' and vice versa; this is
5342 easier to understand and avoids a GCC warning.
5344 2012-04-09 Glenn Morris <rgm@gnu.org>
5346 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5347 preparation for dumping it with emacs. (Bug#4789)
5348 (leimdir): New variable.
5349 ($(leimdir)/leim-list.el): New rule.

5366 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5368 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5369 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5370 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5371 objects, as mark_maybe_pointer will catch them otherwise.
5372 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5373 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5375 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5377 Fix typo that broke non-Windows builds.
5378 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5382 Support building on MS-Windows with libxml2.
5384 * makefile.w32-in (OBJ2): Add xml.$(O).
5385 (GLOBAL_SOURCES): Add xml.c.
5386 ($(BLD)/xml.$(O)): New dependency list.
5388 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5389 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5390 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5391 [!WINDOWSNT]: New macros.
5392 (init_libxml2_functions, libxml2_loaded_p): New functions.
5393 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5394 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5395 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5396 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5398 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5399 Call init_libxml2_functions before calling libxml2 functions.
5400 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5402 * emacs.c: Don't include libxml/parser.h.
5403 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5404 xmlCleanupParser directly.
5406 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5408 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5410 * indent.c (Fvertical_motion): If there is a display string at
5411 point, use it.vpos to compute how many lines to backtrack after
5412 move_it_to point. (Bug#11133)
5414 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5416 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5417 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5418 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5419 macros related to unification of CJK characters. For the details,
5420 see the discussion following the message here:
5421 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5423 2012-04-04 Chong Yidong <cyd@gnu.org>
5425 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5427 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5429 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5430 instead of alloca. (Bug#11138)
5432 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5434 * w32menu.c (is_simple_dialog): Properly check lisp types.
5437 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5439 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5440 position we get to after a call to move_it_to fails the
5441 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5442 only if we wind up in a string from display property. (Bug#11063)
5444 * window.c (Fdelete_other_windows_internal): Invalidate the row
5445 and column information about mouse highlight, so that redisplay
5446 restores it after reallocating the glyph matrices. (Bug#7464)
5448 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5449 string comes from a `display' text property, use the buffer
5450 position of that property as if we actually saw that position in
5452 (move_it_by_lines): Remove the assertion that
5453 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5454 violated when there's a before-string at the beginning of a line.
5457 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5459 * xdisp.c (append_space_for_newline): If the default face was
5460 remapped, use the remapped face for the appended newline.
5461 (extend_face_to_end_of_line): Use the remapped default face for
5462 extending the face to the end of the line.
5463 (display_line): Call extend_face_to_end_of_line when the default
5464 face was remapped. (Bug#11068)
5466 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5468 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5470 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5472 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5474 2012-03-27 Glenn Morris <rgm@gnu.org>
5476 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5479 2012-03-26 Kenichi Handa <handa@m17n.org>
5481 * dispextern.h (struct glyph): Fix previous change. Change the
5482 bit length of glyphless.ch to 25 (Bug#11082).
5484 2012-03-26 Chong Yidong <cyd@gnu.org>
5486 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5487 (command_loop_1): Use it; inhibit selection update for
5488 handle-select-window too (Bug#8996).
5490 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5492 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5494 2012-03-25 Kenichi Handa <handa@m17n.org>
5496 * dispextern.h (struct glyph): Change the bit length of
5497 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5499 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5501 * s/ms-w32.h (tzname): Include time.h before redirecting to
5502 _tzname. Fixes the MSVC build. (Bug#9960)
5504 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5506 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5509 * xterm.c (XTread_socket): Only modify handling_signal if
5510 !SYNC_INPUT. (Bug#11080)
5512 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5514 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5515 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5516 when fetching a multibyte character consumes more bytes than
5517 CHAR_BYTES returns, due to unification of CJK characters in
5518 string_char. (Bug#11073)
5520 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5522 * process.c (wait_reading_process_output): Handle pty disconnect
5523 by refraining from sending oneself a SIGCHLD (bug#10933).
5525 2012-03-22 Chong Yidong <cyd@gnu.org>
5527 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5529 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5530 Mark string as coming from a prefix property.
5531 (handle_face_prop): Use default face for prefix strings (Bug#4281).

5538 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5540 * w32proc.c (Fw32_set_console_codepage)
5541 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5544 2012-03-20 Chong Yidong <cyd@gnu.org>
5546 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5547 to reflect default non-nil value of redisplay-dont-pause.
5549 2012-03-19 Kenichi Handa <handa@m17n.org>
5551 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5552 it fit in a valid range (Bug#11003).
5554 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5556 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5557 that is not from display property, accept the row as a "cursor
5558 row" if one of the string's character has a non-nil `cursor'
5559 property. Fixes cursor positioning when there are newlines in
5560 overlay strings, e.g. in icomplete.el. (Bug#11035)
5562 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5564 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5566 2012-03-12 Chong Yidong <cyd@gnu.org>
5568 * eval.c (inhibit_lisp_code): Rename from
5569 inhibit_window_configuration_change_hook; move from window.c.
5571 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5572 * window.c (run_window_configuration_change_hook)
5573 (syms_of_window): Callers changed.
5575 2012-03-11 Chong Yidong <cyd@gnu.org>

5588 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5590 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5592 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5593 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5596 2012-03-03 Glenn Morris <rgm@gnu.org>
5598 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5600 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5602 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5603 position past the first glyph_row that ends at ZV. (Bug#10902)
5604 (redisplay_window, next_element_from_string): Fix typos in
5606 (redisplay_window): Pass to move_it_vertically the margin in
5607 pixels, not in screen lines.
5609 2012-03-02 Glenn Morris <rgm@gnu.org>
5611 * buffer.c (buffer-list-update-hook): Doc fix.
5613 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5615 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5616 push_it before setting up the iterator for the first overlay
5617 string, even if we have an empty string loaded.
5618 (next_overlay_string): If there's an empty string on the iterator
5619 stack, pop the stack. (Bug#10903)
5621 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5623 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5624 Suggested by Stefan Monnier in
5625 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5626 * alloc.c (widen_to_Lisp_Object): New static function.
5627 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5628 and widening them to Lisp_Objects. This would work even if
5629 USE_LSB_TAG is defined and wide integers are used, which might
5630 happen in a future version of Emacs.
5632 2012-02-25 Chong Yidong <cyd@gnu.org>
5634 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5637 * xselect.c (Fx_selection_exists_p): Doc fix.
5638 (x_clipboard_manager_save_all): Print an informative message
5639 before saving to clipboard manager.
5641 2012-02-24 Chong Yidong <cyd@gnu.org>
5643 * keyboard.c (process_special_events): Handle all X selection
5644 requests in kbd_buffer, not just the next one (Bug#8869).
5646 2012-02-23 Chong Yidong <cyd@gnu.org>

5649 call when setting menu-bar-lines and tool-bar-lines parameters.
5650 (unwind_create_frame_1): New helper function.
5652 * window.c (inhibit_window_configuration_change_hook): New var.
5653 (run_window_configuration_change_hook): Obey it.
5654 (syms_of_window): Initialize it.
5656 2012-02-22 Chong Yidong <cyd@gnu.org>

5671 when computing $valmask.
5673 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5674 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5675 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5676 It's useless in that case, and it can cause problems on hosts
5677 that allocate halves of EMACS_INT values separately.
5678 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5679 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5680 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5681 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5682 it avoids undefined behavior on hosts where shifting right by more
5683 than the word width has undefined behavior.
5685 2012-02-19 Chong Yidong <cyd@gnu.org>
5687 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5688 (Funhandled_file_name_directory, Ffile_name_as_directory)

5691 return values (Bug#10845).
5693 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5695 * .gdbinit (pitx): Fix incorrect references to fields of the
5698 2012-02-17 Chong Yidong <cyd@gnu.org>

5705 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5707 2012-02-15 Chong Yidong <cyd@gnu.org>
5709 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5710 marked as special. Also, starting docstrings with * is obsolete.
5712 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

5725 2012-02-12 Chong Yidong <cyd@gnu.org>
5727 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5728 as that creates a dangerous corner case.
5730 * window.c (Fdelete_window_internal): Invalidate the mouse
5731 highlight (Bug#9904).
5733 2012-02-12 Glenn Morris <rgm@gnu.org>

5736 (Fx_get_selection_internal, Fx_disown_selection_internal)
5737 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5738 * nsselect.m (Fx_own_selection_internal)
5739 (Fx_disown_selection_internal, Fx_selection_exists_p)
5740 (Fx_selection_owner_p, Fx_get_selection_internal):
5741 Sync docs and argument specs with the xselect.c versions.
5743 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

5763 2012-02-07 Chong Yidong <cyd@gnu.org>
5765 * buffer.c (Fbuffer_local_variables)
5766 (buffer_lisp_local_variables): Handle unbound vars correctly;
5767 don't let Qunbound leak into Lisp.
5769 2012-02-07 Glenn Morris <rgm@gnu.org>
5771 * image.c (Fimagemagick_types): Doc fix.
5773 * image.c (imagemagick-render-type): Change it from a lisp object
5774 to an integer. Move the doc here from the lisp manual.

5779 * doc.c (store_function_docstring): Avoid applying docstring of
5780 alias to base function (Bug#2603).

5794 Include --enable-checking, if specified, in the return value.
5796 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5798 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5799 after rounding frame sizes. (Bug#9723)
5801 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5803 * keyboard.c (adjust_point_for_property): Don't position point
5804 before BEGV. (Bug#10696)
5806 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5808 Handle overflow when computing char display width (Bug#9496).
5809 * character.c (char_width): Return EMACS_INT, not int.
5810 (char_width, c_string_width): Check for overflow when

6335 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
6336 of scroll runs so as to avoid assigning disabled bogus rows and
6337 unnecessary graphics copy operations.
6339 2011-11-27 Eli Zaretskii <eliz@gnu.org>
6341 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

6348 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6349 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

6377 * xdisp.c (redisplay_window): If cursor row is not fully visible
6378 after recentering, and scroll-conservatively is set to a large
6379 number, scroll window by a few more lines to make the cursor fully
6380 visible and out of scroll-margin. (Bug#10105)
6381 (start_display): Don't move to the next line if the display should
6382 start at a newline that is part of a display vector or an overlay

6466 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6467 is set, removing the need for VIRT_ADDRESS_VARIES.
6468 (PURE_P): Use a more-efficient implementation that needs just one
6469 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6470 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6471 to 4 (xorl, subq, cmpq, setbe).
6472 * alloc.c (pure): Always extern now, since that's the
6473 VIRT_ADDR_VARIES behavior.
6474 (PURE_POINTER_P): Use a single comparison, not two, for
6475 consistency with the new puresize.h.
6476 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6477 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6483 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6484 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6485 behave as if the cursor position were at the window margin.
6487 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6488 and the cursor position is out of bounds, behave as if the cursor
6489 position were at the window margin. (Bug#10075)
6491 2011-11-18 Chong Yidong <cyd@gnu.org>
6493 * window.c (Fwindow_combination_limit): Make first argument

6515 compute_line_metrics.
6516 (compute_line_metrics): Call row_hash, instead of computing the
6519 * dispnew.c (verify_row_hash): Call row_hash for computing the
6520 hash code of a row, instead of duplicating code from xdisp.c.
6522 * dispextern.h (row_hash): Add prototype.
6524 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6526 * frame.c (delete_frame): Don't delete the terminal when the last

6549 (Fset_window_nest): Rename to Fset_window_combination_limit.
6550 (Vwindow_nest): Rename to Vwindow_combination_limit.
6551 (recombine_windows, make_parent_window, make_window)

6553 (Fset_window_configuration, save_window_save): Rename all
6554 occurrences of window_nest to window_combination_limit.
6556 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6558 * image.c (imagemagick_load_image): Fix typo.
6560 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6562 * xdisp.c (display_line): Move the call to
6563 highlight_trailing_whitespace before the call to
6564 compute_line_metrics, since the latter needs to see the final
6565 faces of all the glyphs to compute ROW's hash value.
6566 Fixes assertion violations in row_equal_p. (Bug#10035)
6568 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6570 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6575 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6576 with user-defined heap size. Bump the default size of the temacs
6577 heap to 27MB, to avoid memory warning when running temacs.
6578 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6580 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6627 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6629 Avoid some portability problems by eschewing 'extern inline' functions.
6630 The trivial performance wins aren't worth the portability hassles; see
6631 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6633 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6635 (window_box_right, window_box_right_offset): Undo previous change,
6636 by removing the "extern"s.
6637 * intervals.c (adjust_intervals_for_insertion)
6638 (adjust_intervals_for_deletion): Undo previous change,
6639 making these static again.
6640 (offset_intervals, temp_set_point_both, temp_set_point)
6641 (copy_intervals_to_string): No longer inline.
6642 * xdisp.c (window_text_bottom_y, window_box_width)

6699 * xmenu.c (cleanup_widget_value_tree): New function.
6700 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6707 (window_box_width, window_box_left, window_box_left_offset)
6708 (window_box_right, window_box_right_offset): Declare extern.
6709 Otherwise, these inline functions do not conform to C99 and
6710 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6711 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6712 * intervals.c (adjust_intervals_for_insertion)
6713 (adjust_intervals_for_deletion): Now extern, because otherwise the
6714 extern inline functions 'offset_intervals' couldn't refer to it.
6715 (static_offset_intervals): Remove.
6716 (offset_intervals): Rewrite using the old contents of
6717 static_offset_intervals. The old version didn't conform to C99
6718 because an extern inline function contained a reference to an
6719 identifier with static linkage.
6721 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6723 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6741 (Fwindow_vscroll): Doc fix.
6742 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6743 argument, since it makes no sense to pass a live window and for

6772 (unwind_create_frame): New function (Bug#9943).
6773 (Fx_create_frame): Restructure code to be more similar to the one in
6774 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6775 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6776 Move terminal->reference_count++ just before making the frame official

6785 official. Move initialization of image_cache_refcount and
6786 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

6854 (mouse_face_from_buffer_pos, note_mouse_highlight):
6855 Rename cover_string to disp_string.
6857 2011-11-01 Martin Rudalics <rudalics@gmx.at>

6917 Not clear what it was for, and it causes various bugs. (Bug#9839)
6919 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6921 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6922 possible random value that matches one of those tested as
6923 condition to clear the mouse face.
6925 2011-10-28 Chong Yidong <cyd@gnu.org>
6927 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

6951 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6952 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6954 (w32font_open_internal, compute_metrics):
6955 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6956 instead of calling the "wide" APIs directly.
6958 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6960 * w32.h (syms_of_w32font): Add prototype.
6962 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6999 extracted from Fw32_default_color_map.
7000 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
7002 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
7004 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
7006 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
7008 * keyboard.c (test_undefined): New function (bug#9751).
7009 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7011 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7013 * sysdep.c (init_sys_modes): Fix the check for the controlling
7014 terminal (Bug#6649).
7016 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7018 * dispextern.h (struct bidi_it): New member next_en_type.
7020 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7021 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7022 current character, check also for next_en_type being WEAK_EN.
7023 (bidi_resolve_weak): Don't enter the expensive loop if the current
7024 position is before next_en_pos. Record the bidi type of the first
7025 non-ET, non-BN character we find, in addition to its position.
7026 (bidi_level_of_next_char): Invalidate next_en_type when
7027 next_en_pos is over-stepped.
7029 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7031 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7032 * editfns.c: Rewrite current-time-zone so that it invokes
7033 the equivalent of (format-time-string "%Z") to get the time zone name.
7034 This fixes a bug when the time zone name contains characters that
7035 need converting from the system time locale to Emacs internal format.
7036 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7037 that patch fixed format-time-string to do the conversion, but
7038 I forgot to fix current-time-zone.
7039 (format_time_string): New function, containing most of
7040 what Fformat_time_string used to contain.
7041 (Fformat_time_string): Rewrite in terms of format_time_string.
7042 This doesn't change this function's behavior.
7043 (current-time-zone): Rewrite to use format_time_string.
7044 This fixes the bug reported by Michael Schierl in
7045 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7046 Jason Rumney's 2007-06-07 change worked around this bug, but
7048 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7050 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7052 * xdisp.c (start_display): If the character at POS is displayed
7053 via a display vector, reset IT->current.dpvec_index to zero.
7054 (try_window_reusing_current_matrix): If a line ends in a display
7055 vector or the next line starts in a display vector, continue
7056 redrawing the window even though the character position of
7057 start_row was reached.
7060 2011-10-18 Chong Yidong <cyd@gnu.org>
7062 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7063 with nobreak-char-display too.
7065 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7067 Fix part 3 of bug#9771.
7068 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7069 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7070 non-neutral characters if the current character is a paragraph
7071 separator (a.k.a. Newline). This avoids running the same
7072 expensive loop twice, once when we consume the preceding newline
7073 and the other time when the line actually needs to be displayed.
7074 Avoid the loop when we see neutrals on the base embedding level
7075 following a character whose directionality is the same as the
7076 paragraph's. This avoids running the expensive loop when a line
7077 ends in a long sequence of neutrals, like control characters.
7078 Add assertion against STRONG_AL type. Slightly rearrange code
7079 that determines the type of a neutral given the first non-neutral
7081 (bidi_level_of_next_char): Set next_en_pos to zero when
7082 invalidating its info.
7084 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7086 * xdisp.c (push_display_prop): Determine whether to record string
7087 or buffer position by IT->string, not by IT->method. Allow
7088 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7089 (move_it_vertically_backward): Don't look for character position
7090 immediately after the newline when in a continuation line.
7093 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7095 * window.c (coordinates_in_window): Rewrite and delabelize
7096 vertical border check. (Bug#5357) (Bug#9618)
7098 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7100 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7101 errors in XSetWindowBorder (bug#9310).
7103 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7105 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7106 avoid crash when xmalloc overrun checking is enabled.
7108 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7110 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7111 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7112 cursor motion with <left> and <right> arrow keys.
7114 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7115 some callers set that themselves.
7117 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7119 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7120 display string and the previous row comes from the same string and
7121 is empty. (Bug#9739) (Bug#9738)
7123 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7125 * doc.c (get_doc_string): Encode file name (bug#9735).
7127 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7129 * bidi.c (bidi_level_of_next_char):
7130 * xdisp.c (get_visually_first_element): Remove old incorrect
7131 comments regarding the Unicode Line Separator character.
7133 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7135 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7137 * alloc.c (Fgc_status): Do not access beyond zombies array
7138 boundary if nzombies > MAX_ZOMBIES.
7139 * alloc.c (dump_zombies): Add missing format specifier.
7141 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7143 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7144 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7146 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7147 Some packages use them to denote characters with modifiers.
7149 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7151 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7152 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7153 matching a pp-number. Rename parameter var to var1.
7155 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7157 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7159 2011-10-08 Glenn Morris <rgm@gnu.org>
7161 * callint.c (Fcall_interactively): Give a more explicit error for the
7162 'c' case with a non-character input. (Bug#8479)
7164 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7166 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7168 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7169 lines that are hscrolled on the left.
7171 * dispnew.c (buffer_posn_from_coords): Account for a possible
7172 presence of header-line. (Bug#4426)
7174 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7176 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7177 Don't advertise functionality which we discourage or doesn't work.
7179 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7181 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7182 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7183 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7184 this makes Emacs dump core during garbage collection on rare
7185 occasions. sizeof is obviously inferior to offsetof here, so
7186 stick with offsetof.
7187 (GC_POINTER_ALIGNMENT): New macro.
7188 (mark_memory): Omit 3rd (offset) arg; caller changed.
7189 Don't assume EMACS_INT alignment is the same as pointer alignment.
7191 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7193 * keyboard.c (read_key_sequence_remapped): New var.
7194 (read_key_sequence): Compute remapping in the right buffer.
7195 (command_loop_1): Use read_key_sequence's remapping directly.
7197 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7199 * dired.c (file_name_completion): Don't expand file name.
7200 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7201 before checking file name handler.
7203 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7204 they've been requested explicitly (bug#9591).
7206 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7208 * keymap.c (Fsingle_key_description): Use make_specified_string
7209 instead of build_string to build string from push_key_description.
7212 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7214 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7215 This fixes a Y2038 bug on 64-bit hosts.
7216 * buffer.c (reset_buffer):
7217 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7218 (Fclear_buffer_auto_save_failure):
7219 Use 0, not -1, to represent an unset failure time, since time_t
7220 might not be signed.
7222 Remove dependency on glibc malloc internals.
7223 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7224 Move back here from lisp.h, but with their new implementations.
7225 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7226 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7227 * charset.c (charset_table_init): New static var.
7228 (syms_of_charset): Use it instead of xmalloc. This removes a
7229 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7230 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7231 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7232 Move back to alloc.c.
7233 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7234 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7236 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7238 * nsterm.m (windowDidResize): Call x_set_window_size only when
7239 ns_in_resize is true. Otherwise set pixelwidth/height and
7240 call change_frame_size (Bug#9628).
7242 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7244 Port --enable-checking=all to Fedora 14 x86-64.
7245 * charset.c (syms_of_charset): Also account for glibc malloc's
7246 internal overhead when calculating the initial malloc maximum.
7248 Port --enable-checking=all to Fedora 14 x86.
7249 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7251 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7252 (overrun_check_realloc, overrun_check_free):
7253 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7254 That way, xmalloc returns a properly-aligned pointer even if
7255 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7256 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7257 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7258 into account when calculating the initial malloc maximum.
7259 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7260 Move here from alloc.c, so that charset.c can use it too.
7261 Properly align; the old code wasn't right for common 32-bit hosts
7262 when configured with --enable-checking=all.
7263 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7264 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7266 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7268 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7271 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7273 * xdisp.c (compute_display_string_end): If there's no display
7274 string at CHARPOS, return -1.
7276 * bidi.c (bidi_fetch_char): When compute_display_string_end
7277 returns a negative value, treat the character as a normal
7278 character not covered by a display string. (Bug#9624)
7280 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7282 * lread.c (Fread_from_string): Fix typo in docstring.
7284 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7286 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7287 newline, reseat the iterator instead of bidi-iterating there one
7288 character at a time. (Bug#9610)
7289 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7290 TO_CHARPOS if the bidi iterator is at base embedding level.
7292 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7294 * lread.c (readevalloop): Use correct code for NBSP.
7295 (read1): Likewise. (Bug#9608)
7297 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7299 * dbusbind.c (Fdbus_register_signal): When service is not
7300 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7302 2011-09-25 Glenn Morris <rgm@gnu.org>
7304 * buffer.c (truncate-lines): Doc fix.
7306 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7308 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7309 (Fset_window_next_buffers): Doc fix.
7311 2011-09-24 Glenn Morris <rgm@gnu.org>
7313 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7315 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7317 Fix minor problems found by static checking.
7318 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7319 * indent.c (Fvertical_motion): Fix == vs = typo.
7321 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7323 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7324 Default value is now t. Doc fix.
7326 * indent.c (Fvertical_motion): Compute and apply the overshoot
7327 logic when moving up, not only when moving down. Fix the
7328 confusing name and values of the it_overshoot_expected variable;
7329 logic changes accordingly. (Bug#9254) (Bug#9549)
7331 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7332 CHARPOS is covered by a display string which includes newlines.
7333 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7334 is covered by a display string with embedded newlines.
7336 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7338 * dbusbind.c (Fdbus_register_signal): Add match rule to
7339 Vdbus_registered_objects_table. (Bug#9581)
7340 (Fdbus_register_method, Vdbus_registered_objects_table):
7343 2011-09-24 Jim Meyering <meyering@redhat.com>
7345 do not ignore write error for any output size
7346 The previous change was incomplete.
7347 While it makes emacs --batch detect the vast majority of stdout
7348 write failures, errors were still ignored whenever the output size is
7349 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7350 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7351 && echo FAIL: ignored write error
7352 FAIL: ignored write error
7353 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7354 && echo FAIL: ignored write error
7355 FAIL: ignored write error
7356 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7358 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7360 * emacs.c (Fkill_emacs): In noninteractive mode exit
7361 non-successfully if a write error occurred on stdout. (Bug#9574)
7363 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7365 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7368 * dispextern.h (struct it): Update the comment documenting what
7371 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7373 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7374 a display string, extend search for cursor position to end of row.
7375 (find_row_edges): If the row ends in a newline from a display
7376 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7377 Handle the case of a display string with multiple newlines.
7378 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7379 non-empty line. Fixes confusing cursor motion with arrow keys at
7380 the beginning of a line that starts with whitespace.
7382 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7384 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7387 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7389 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7392 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7394 * xdisp.c (display_line): Record maximum and minimum buffer
7395 positions even if no glyphs were produced (e.g., by a zero-width
7396 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7397 buffer positions that will be removed from the glyph row because
7399 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7400 column is beyond frame width: don't subtract 1 "pixel" when
7401 computing width of the stretch.
7402 (reseat_at_next_visible_line_start): Undo the change made on
7403 2011-09-17 that saved paragraph information and restored it after
7404 the call to `reseat'. (Bug#9545)
7406 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7408 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7409 and turn window cursor on if cleared (Bug#9415).
7411 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7413 * search.c (boyer_moore): Take unibyte characters from pattern
7414 literally. (Bug#9458)
7416 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7418 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7420 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7422 Fix minor problem found by static checking.
7423 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7424 initialized, to pacify gcc -Wuninitialized.
7426 * fileio.c: Report proper errno when syscall falls.
7427 (Finsert_file_contents): Save and restore errno,
7428 so that report_file_error outputs the correct diagnostic.
7429 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7431 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7433 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7435 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7437 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7438 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7440 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7442 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7443 about the current paragraph and restore it after the call to reseat.
7445 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7446 (bidi_find_paragraph_start): Search back for paragraph beginning
7447 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7448 (bidi_move_to_visually_next): Only trigger paragraph-related
7449 computations when the last character is a newline or at EOB, not
7450 just any NEUTRAL_B. (Bug#9470)
7452 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7453 truncated lines if point is covered by a display string. (Bug#9524)
7455 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7457 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7458 (cons_to_x_long): New function.
7459 (lisp_data_to_selection_data): Use it. Correct the test for
7460 short-versus-long data; it was negated. Break out of vector
7461 loop, for efficiency, when a long datum is discovered.
7463 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7465 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7467 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7469 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7470 GCC PR/17406) by declaring this function with external scope.
7472 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7474 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

7489 of TAB characters in a composition.
7491 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7493 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7494 This occurs when processing a multibyte format.
7495 Problem reported by Wolfgang Jenker.
7497 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7499 * xdisp.c (try_cursor_movement): Only check for exact match if
7500 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7502 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7504 Remove unused external symbols.
7505 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7506 * xdisp.c (calc_pixel_width_or_height): Now static.
7507 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7508 * indent.c (check_display_width):
7509 * w32term.c: Fix comment to match code.
7510 * xterm.c, xterm.h (x_catching_errors): Remove.
7512 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7514 * xselect.c: Use signed conversions more consistently (Bug#9498).
7515 (selection_data_to_lisp_data): Assume incoming selection data are
7516 signed integers, not unsigned. This is to be consistent with
7517 outgoing selection data, which was modified to use signed integers
7518 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7519 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7520 expects long, not unsigned long.
7522 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7524 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7525 computation of loop end. Reported by Johan Bockgård
7528 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7530 * frame.c (Fother_visible_frames_p): Function deleted.
7532 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7534 * indent.c (compute_motion): Process display vector front to back
7535 rather than the other way around. (Bug#2496)
7537 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7539 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7541 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7543 * minibuf.c (Fread_from_minibuffer): Doc fix.
7545 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7547 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7548 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7550 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7552 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7553 value for non-existent files.
7555 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7557 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7558 set its "size" to -1. This will set the modtime_size field of
7559 the corresponding buffer to -1, which is what
7560 verify-visited-file-modtime expects for files that do not exist.
7563 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7565 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7567 * lisp.h: ... from here. push_key_description is no longer
7568 defined in keyboard.c, so its declaration should not be in
7569 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7570 logically belongs with push_key_description.
7572 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7574 * buffer.h: Include <sys/types.h> instead of <time.h>.
7575 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7576 Problem reported by Herbert J. Skuhra.
7578 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7580 * xml.c (parse_region): Make the parsing work for
7581 non-comment-starting XML files again (bug#9144).
7583 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7585 * image.c (gif_load): Fix calculation of bottom and right corner.
7588 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7590 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7591 redisplay in small windows.
7593 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7595 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7597 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7599 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7600 Operate on live windows only.
7602 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7604 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7606 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7608 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7609 only under bidi iteration.
7611 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7613 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7615 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7617 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7618 Without this fix, the command to link temacs failed due to an
7619 undefined symbol __builtin_isnan. This is because
7620 /usr/include/iso/math_c99.h #defines isnan(x) to
7621 __builtin_isnan(x), but the bundled gcc, which identifies itself
7622 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7624 * floatfns.c (isnan): #undef, and then #define to a clone of
7626 (Fisnan): Always define, since it's always available now.
7627 (syms_of_floatfns): Always define isnan at the Lisp level.
7629 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7631 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7633 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7635 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7636 The previous code assumed that file offsets (off_t values) fit in
7637 EMACS_INT variables, which is not true on typical 32-bit hosts.
7638 The code messed up by falsely reporting buffer overflow in cases
7639 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7640 when "big" contains more than 2**29 bytes, even though this
7641 inserts just one byte and does not overflow the buffer.
7642 (Finsert_file_contents): Store file offsets as off_t
7643 values, not as EMACS_INT values. Check for overflow when
7644 converting between EMACS_INT and off_t. When checking for
7645 buffer overflow or for overlap, take the offsets into account.
7646 Don't use EMACS_INT for small values where int suffices.
7647 When checking for overlap, fix a typo: ZV was used where
7648 ZV_BYTE was intended.
7649 (Fwrite_region): Don't assume off_t fits into 'long'.
7650 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7652 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7654 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7656 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7658 sprintf-related integer and memory overflow issues (Bug#9412).
7660 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7661 (esprintf, exprintf, evxprintf): New functions.
7662 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7663 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7664 (modify_event_symbol): Do not assume that the length of
7665 name_alist_or_stem is safe to alloca and fits in int.
7666 (Fexecute_extended_command): Likewise for function name and binding.
7667 (Frecursion_depth): Wrap around reliably on integer overflow.
7668 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7669 since some callers pass EMACS_INT values.
7670 (Fsingle_key_description): Don't crash if symbol name contains more
7671 than MAX_ALLOCA bytes.
7672 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7673 (get_minibuffer): Arg is now EMACS_INT, not int.
7674 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7675 (esprintf, exprintf, evxprintf): New decls.
7676 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7678 * dbusbind.c (signature_cat): New function.
7679 (xd_signature, Fdbus_register_signal):
7680 Do not overrun buffer; instead, report string overflow.
7682 * dispnew.c (add_window_display_history): Don't overrun buffer.
7683 Truncate instead; this is OK since it's just a log.
7685 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7686 even if the time zone offset is outlandishly large.
7687 Don't mishandle offset == INT_MIN.
7689 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7690 when creating daemon; the previous buffer-overflow check was incorrect.
7692 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7693 which has the guts of the old verror function.
7695 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7696 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7698 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7699 (font_unparse_xlfd): Don't blindly alloca long strings.
7700 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7701 fits in int, when using sprintf. Use single snprintf to count
7702 length of string rather than counting it via multiple sprintfs;
7703 that's simpler and more reliable.
7704 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7705 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7706 sprintf, in case result does not fit in int.
7708 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7709 (fontset_from_font): Print it.
7711 * frame.c (tty_frame_count): Now printmax_t, not int.
7712 (make_terminal_frame, set_term_frame_name): Print it.
7713 (x_report_frame_params): In X, window IDs are unsigned long,
7714 not signed long, so print them as unsigned.
7715 (validate_x_resource_name): Check for implausibly long names,
7716 and don't assume name length fits in 'int'.
7717 (x_get_resource_string): Don't blindly alloca invocation name;
7718 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7721 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7722 (xg_check_special_colors, xg_set_geometry):
7723 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7725 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7726 Use esprintf, not sprintf, in case result does not fit in int.
7728 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7729 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7730 it as a large positive number.
7731 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7732 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7734 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7735 in case result does not fit in int.
7737 * print.c (float_to_string): Detect width overflow more reliably.
7738 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7739 buffer overrun. Don't assume list length fits in 'int'. Treat
7740 print length of 0 as 0, not as infinity; to be consistent with other
7741 uses of print length in this function. Don't overflow print length
7742 index. Don't assume hash table size fits in 'long', or that
7743 vectorlike size fits in 'unsigned long'.
7745 * process.c (make_process): Use printmax_t, not int, to format
7746 process-name gensyms.
7748 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7750 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7751 to avoid potential buffer overrun.
7753 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7754 if X resource line is longer than 512 bytes.
7756 * xfns.c (x_window): Make sprintf buffer a bit bigger
7757 to avoid potential buffer overrun.
7759 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7763 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7765 Integer overflow fixes for scrolling, etc.
7766 Without these, Emacs silently mishandles large integers sometimes.
7767 For example, "C-u 4294967297 M-x recenter" was treated as if
7768 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7770 * xdisp.c (try_window_id): Check Emacs fixnum range before
7771 converting to 'int'.
7773 * window.c (window_scroll_line_based, Frecenter):
7774 Check that an Emacs fixnum is in range before assigning it to 'int'.
7775 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7776 values converted from Emacs fixnums.
7777 (Frecenter): Don't wrap around a line count if it is out of 'int'
7778 range; instead, treat it as an extreme value.
7779 (Fset_window_configuration, compare_window_configurations):
7780 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7782 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7783 that can exceed INT_MAX. Check that EMACS_INT value is in range
7784 before assigning it to the (possibly-narrower) index.
7785 (match_limit): Don't assume that a fixnum can fit in 'int'.
7787 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7790 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7791 (Fvertical_motion): Don't wrap around LINES values that don't fit
7792 in 'int'. Instead, treat them as extreme values. This is good
7793 enough for windows, which can't have more than INT_MAX lines anyway.
7795 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7797 * Require libxml/parser.h to avoid compilation warning.
7799 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7801 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7802 since this reportedly can destroy thread storage.
7804 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7806 * syntax.c (find_defun_start): Update all cache variables if
7807 exiting early (Bug#9401).
7809 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7811 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7813 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7814 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7815 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7817 * term.c (tty_append_glyph): New function.
7818 (produce_stretch_glyph): Static function and its prototype deleted.
7820 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7823 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7825 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7826 when checking :margin (Bug#9390).
7827 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7828 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7829 so that the name doesn't mislead. All uses changed.
7831 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7833 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7836 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7838 * xdisp.c (move_it_to): Don't bail out early when reaching
7839 position beyond to_charpos, if we are scanning backwards.
7840 (move_it_vertically_backward): When DY == 0, make sure we get to
7841 the first character in the line after the newline.
7843 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7845 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7846 (ccl_driver): Do not generate an out-of-range pointer.
7847 (Fccl_execute_on_string): Remove unnecessary check for
7848 integer overflow, noted by Stefan Monnier in
7849 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7850 Remove a FIXME that didn't need fixing.
7851 Simplify the newly-introduced buffer reallocation code.
7853 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7855 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7857 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7859 Integer and memory overflow issues (Bug#9196).
7861 * doc.c (get_doc_string): Rework so that
7862 get_doc_string_buffer_size is the actual buffer size, rather than
7863 being 1 less than the actual buffer size; this makes xpalloc more
7866 * image.c (x_allocate_bitmap_record, cache_image):
7867 * xselect.c (Fx_register_dnd_atom):
7868 Simplify previous changes by using xpalloc.
7870 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7871 since either will do and ptrdiff_t is convenient with xpalloc.
7873 * charset.c (charset_table_size)
7874 (struct charset_sort_data.priority): Now ptrdiff_t.
7875 (charset_compare): Don't overflow if priorities differ greatly.
7876 (Fsort_charsets): Don't assume list length fits in int.
7877 Check for size-calculation overflow when allocating sort data.
7878 (syms_of_charset): Allocate an initial charset table that is
7879 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7881 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7883 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7884 The actual value is always <= INT_MAX, and leaving it unsigned made
7885 overflow checking harder.
7887 * dispextern.h (struct glyph_matrix.rows_allocated)
7888 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7889 with xpalloc. The values are still always <= INT_MAX.
7891 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7893 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7894 (SAFE_NALLOCA): New macro.
7896 * region-cache.c (struct boundary.pos, find_cache_boundary)
7897 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7898 (set_cache_region, invalidate_region_cache)
7899 (revalidate_region_cache, know_region_cache, region_cache_forward)
7900 (region_cache_backward, pp_cache):
7901 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7902 so that ptrdiff_t * can be passed to xpalloc.
7903 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7904 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7905 (pp_cache): Don't assume cache_len fits in int.
7906 * region-cache.h: Adjust extern decls to match.
7908 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7909 EMACS_INT, since either will do, for xpalloc.
7911 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7912 (xnmalloc, xnrealloc, xpalloc): New functions.
7914 * bidi.c (bidi_shelve_header_size): New constant.
7915 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7916 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7918 * bidi.c (bidi_cache_shrink):
7919 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7921 Don't update size of array until after memory allocation succeeds,
7922 because xmalloc/xrealloc may not return.
7923 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7924 now that we have proper integer overflow checking.
7925 (record_overlay_string, overlay_strings): Catch overflows when
7926 calculating size of overlay_str_buf.
7928 * callproc.c (Fcall_process): Check for size overflow when
7929 calculating size of args2.
7930 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7931 Normally we prefer signed values, but sticking with ptrdiff_t would
7932 require adding more-complicated checks.
7934 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7935 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7936 Redo buffer-overflow calculations to avoid integer overflow.
7937 Add a FIXME comment where memory seems to be over-allocated.
7939 * character.c (Fstring): Check for size-calculation overflow.
7941 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7942 unnecessary integer overflow. Check for size overflow.
7943 (encode_coding_object): Don't update size until xmalloc succeeds.
7945 * composite.c (get_composition_id): Check for overflow in glyph
7946 length calculations.
7948 Integer and memory overflow fixes for display code.
7949 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7950 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7951 (scrolling_window): Check for overflow in size calculations.
7952 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7963 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7964 (get_doc_string): Check for size calculation overflow.
7965 Don't update size until allocation succeeds.
7966 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7967 EMACS_INT, where ptrdiff_t will do.
7968 (Fsubstitute_command_keys): Check for string overflow.
7970 * editfns.c (set_time_zone_rule): Don't assume environment length
7972 (message_length): Now ptrdiff_t, not int.
7973 (Fmessage_box): Don't update size until allocation succeeds.
7974 Don't assume message length fits in int.
7975 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7977 * emacs.c (main): Do not reallocate argv, since there is a null at
7978 the end that can be overwritten, and this way there's no need to
7979 worry about size-calculation overflow.
7980 (sort_args): Check for size-calculation overflow.
7982 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7984 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7986 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7987 (x_set_scroll_bar_width, x_figure_window_size):
7988 Check for integer overflow.
7989 (x_set_alpha): Do not assume XINT fits in int.
7991 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7992 This is for the members text_lines, text_cols, total_lines, total_cols,
7993 where the system imposes an 'int' limit.
7995 * fringe.c (Fdefine_fringe_bitmap):
7996 Don't update size until alloc works.
7998 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7999 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8001 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8002 Check for size-calculation overflow.
8003 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8004 do, as we prefer signed integers.
8005 (id_to_widget.max_size, id_to_widget.used)
8006 (xg_store_widget_in_map, xg_remove_widget_from_map)
8007 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8008 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8009 Use and return ptrdiff_t, not int.
8010 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8011 * gtkutil.h: Change prototypes to match the above.
8013 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8014 are duplicate now that they've been promoted to lisp.h.
8015 (x_allocate_bitmap_record, x_alloc_image_color)
8016 (make_image_cache, cache_image, xpm_load):
8017 Don't update size until alloc is done.
8018 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8020 Check for size calculation overflow.
8021 (ct_colors_allocated_max): New constant.
8022 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

8027 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8028 Use ptrdiff_t, not int, to count maps.
8029 (read_char_minibuf_menu_prompt): Check for overflow in size
8030 calculations. Don't update size until allocation succeeds.

8042 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8044 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8045 Now ptrdiff_t, not int.
8046 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8047 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.

8057 * search.c (Freplace_match): Check for size calculation overflow.
8058 (Fset_match_data): Don't assume list lengths fit in 'int'.
8060 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8061 for command line length. Do not attempt to address one before the
8062 beginning of an array, as that's not portable.

8065 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8067 (encode_terminal_code, calculate_costs): Check for size
8068 calculation overflow.

8070 table lengths and related sizes. Don't update size until alloc
8071 done. Redo calculations to avoid overflow.
8072 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8074 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

8090 Use ptrdiff_t, not int, for sizes.
8091 (Finternal_make_lisp_face, cache_face):
8092 Check for size calculation overflow.
8093 (cache_face): Treat size calculation overflows as if they were
8094 memory exhaustion (the usual treatment), rather than aborting.
8096 * xfns.c (x_encode_text, x_set_name_internal)
8097 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8098 sizes, since they can exceed INT_MAX in size. Check for size
8099 calculation overflow.
8101 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8102 (xg_select): Check for size calculation overflow.
8103 Don't update size until alloc done.
8105 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8106 as sprintf is limited to int lengths.
8108 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8109 (X_LONG_MIN): New macros.
8110 Use them to make the following changes clearer.
8111 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8112 This change doesn't affect the value now, but it may help remind
8113 future maintainers not to raise the value too much later.
8114 (SELECTION_QUANTUM): Remove, replacing with ...
8115 (selection_quantum): ... new function, which avoids overflow.
8117 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8118 assumption that selection length fits in 'int'.
8119 (x_reply_selection_request, x_handle_selection_request)
8120 (x_get_window_property, receive_incremental_selection)
8121 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8122 (lisp_data_to_selection_data, clean_local_selection_data):

8126 Redo calculations to avoid overflow.
8127 (x_reply_selection_request): When sending hint, ceiling it at
8128 X_LONG_MAX rather than relying on wraparound overflow to send

8131 (lisp_data_to_selection_data, x_property_data_to_lisp):
8132 Check for size-calculation overflow.
8133 (x_get_window_property, receive_incremental_selection)

8135 Don't store size until memory allocation succeeds.
8136 (x_get_window_property): Plug memory leak on memory exhaustion.
8137 Don't double-block input; malloc is safe here. Don't assume 2**34
8138 - 4 fits in unsigned long. Add an xassert to check
8139 XGetWindowProperty overflow. Be more careful about overflow
8140 calculations, and distinguish size from memory overflow better.
8141 (receive_incremental_selection): When tracing, don't assume
8142 unsigned int is less than INT_MAX.
8143 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8144 harmful) conversions of unsigned short to int.
8145 (lisp_data_to_selection_data): Don't assume that integers
8146 in the range -65535 through -1 fit in an X unsigned short.
8147 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8148 result parameters unless successful. Rely on cons_to_unsigned
8149 to report problems with elements; the old code wasn't right anyway.
8150 (x_check_property_data): Check for int overflow; we cannot use
8151 a wider type due to X limits.
8152 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8186 Use ptrdiff_t for hash table indexes, not int (which is too
8187 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8188 32-bit --with-wide-int hosts).
8190 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8191 Add a FIXME comment about memory leaks.
8192 (syms_of_charset): Don't assume xmalloc returns.
8194 Don't assume that stated character widths fit in int.
8195 * character.c (Fchar_width, c_string_width, lisp_string_width):
8196 * character.h (CHAR_WIDTH):
8197 * indent.c (MULTIBYTE_BYTES_WIDTH):
8198 Use sanitize_char_width to avoid undefined and/or bad behavior
8199 with outlandish widths.
8200 * character.h (sanitize_tab_width): Rename from sanitize_width,
8201 now that we have two such functions. All uses changed.
8202 (sanitize_char_width): New inline function.
8204 Don't assume that tab-width fits in int.
8205 * character.h (sanitize_width): New inline function.
8206 (SANE_TAB_WIDTH): New macro.
8207 (ASCII_CHAR_WIDTH): Use it.
8208 * indent.c (sane_tab_width): Remove. All uses replaced by
8209 SANE_TAB_WIDTH (current_buffer).
8210 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
8212 * fileio.c: Integer overflow issues with file modes.
8213 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
8215 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
8216 Remove unreachable code.

8219 * xterm.c: Don't go over XClientMessageEvent limit.
8220 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8221 (x_send_scroll_bar_event): Likewise. Check that the size does not
8222 exceed limits imposed by XClientMessageEvent, as well as the usual
8223 ptrdiff_t and size_t limits.
8225 * keyboard.c: Overflow, signedness and related fixes.
8226 (make_lispy_movement): Use same integer type in forward decl
8227 that is used in the definition.
8228 (read_key_sequence, keyremap_step):
8229 Change bufsize argument back to int, undoing my 2011-03-30 change.
8230 We prefer signed types, and int is wide enough here.
8231 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8232 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8233 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8234 length, not size_t. Use ptrdiff_t for index, not int.
8235 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8236 possibility of integer overflow.
8238 Overflow, signedness and related fixes for images.
8240 * dispextern.h (struct it.stack[0].u.image.image_id)
8241 (struct_it.image_id, struct image.id, struct image_cache.size)

8247 * nsmenu.m (update_frame_tool_bar):
8248 * xdisp.c (calc_pixel_width_or_height):
8249 * xfns.c (image_cache_refcount):
8250 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8251 on typical 64-bit hosts.
8253 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8254 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8257 when the callers expect that.
8258 (image_ascent): Redo ascent calculation to avoid int overflow.
8259 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8260 (lookup_image): Remove unnecessary tests.
8261 (xbm_image_p): Locals are now of int, not EMACS_INT,
8262 since parse_image_check makes sure they fit into int.
8263 (png_load, gif_load, svg_load_image):
8264 Prefer int to unsigned where either will do.
8265 (tiff_handler): New function, combining the cores of the
8266 old tiff_error_handler and tiff_warning_handler.
8267 This function is rewritten to use vsnprintf and thereby avoid
8268 stack buffer overflows. It uses only the features of vsnprintf
8269 that are common to both POSIX and native Microsoft.
8270 (tiff_error_handler, tiff_warning_handler): Use it.
8271 (tiff_load, gif_load, imagemagick_load_image):
8272 Don't assume :index value fits in 'int'.
8273 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8274 (imagemagick_load_image): Check that crop parameters fit into
8275 the integer types that MagickCropImage accepts. Don't assume
8276 Vimagemagick_render_type has a nonnegative value. Don't assume
8277 size_t fits in 'long'.
8278 (gs_load): Use printmax_t to print the widest integers possible.
8279 Check for integer overflow when computing image height and width.
8281 2011-08-26 Eli Zaretskii <eliz@gnu.org>
8283 * xdisp.c (redisplay_window): Don't force window start if point

8288 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8289 the display spec is of the form `(space ...)'.
8290 (handle_display_spec): Return the value returned by
8291 handle_single_display_spec, not just 1 or zero.
8292 (handle_single_display_spec): If the display spec is of the form
8293 `(space ...)', and specifies display in the text area, return 2
8295 (try_cursor_movement): Check for the need to scroll more
8296 accurately, and prefer exact match for point under bidi.
8297 Don't advance `row' beyond the last row of the window.
8299 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8300 into disp_prop; all users changed.
8302 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8303 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8304 for the text covered by the display property.
8306 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8308 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8314 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8315 buffers, return left-to-right.
8316 (set_cursor_from_row): Consider candidate row a win if its glyph
8317 represents a newline and point is on that newline. Fixes cursor
8318 positioning on the newline at EOL of R2L text within L2R
8319 paragraph, and vice versa.
8320 (try_cursor_movement): Check continued rows, in addition to
8321 continuation rows. Fixes unwarranted scroll when point enters a
8322 continued line of R2L text within an L2R paragraph, or vice versa.
8323 (cursor_row_p): Consider the case of point being equal to
8324 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8325 from the end of a short line to the beginning of a continued line
8326 of R2L text within L2R paragraph.
8327 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8328 composed characters.
8330 * bidi.c (bidi_check_type): Use xassert.
8331 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8334 2011-08-23 Eli Zaretskii <eliz@gnu.org>

8339 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8341 * nsfont.m (ns_otf_to_script): Fix typo.
8343 2011-08-22 Kenichi Handa <handa@m17n.org>
8345 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8346 extra slot even if the purpose is char-code-property-table.
8348 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8350 * xdisp.c (redisplay_window): When computing centering_position,
8351 account for the height of the header line. (Bug#8874)
8353 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8354 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8355 candidate is selected by the mouse, and that candidate has a
8356 composed character under the mouse.
8358 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8359 coordinates reported by pos-visible-in-window-p for a composed
8360 character in column zero.
8362 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8364 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8366 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8368 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8369 consider it a hit if to_charpos is anywhere in the range of the
8370 composed buffer positions.
8372 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8374 * image.c (gif_load): Don't assume that each subimage has the same
8375 dimensions as the base image. Handle disposal method that is
8376 "undefined" by the gif spec (Bug#9335).
8378 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8380 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8381 (Fcondition_case): Document `debug' symbol in error handler.
8383 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8385 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8386 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8387 from an Org mode buffer to a Speedbar frame.
8389 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8390 a composition, take its buffer position from IT->cmp_it.charpos.
8391 Fixes cursor positioning at the beginning of a line that begins
8392 with a composed character.
8394 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8396 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8397 character bidirectional type, use STRONG_L instead. Fixes crashes
8398 in a buffer produced by `describe-categories'.
8400 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8401 members before the level stack, so they would be saved and
8402 restored when copying iterator state. Fixes incorrect reordering
8403 around TABs covered by display properties.
8405 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8407 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8415 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8417 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8418 has no `load' handler, try opening the file locally. (Bug#9311)
8420 2011-08-16 Ken Brown <kbrown@cornell.edu>

8477 * xdisp.c (move_it_in_display_line_to): Don't invoke
8478 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8479 ppos_it. Fixes vertical cursor motion when line beginning is
8480 covered by an image. (Bug#9296)
8482 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8484 * nsterm.h (ns_run_ascript): Declare.

8487 * nsfns.m (as_script, as_result, as_status): New static variables.
8488 (ns_run_ascript): New function.
8489 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8490 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8491 the event loop. Get status from as_status (Bug#7276).
8493 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8494 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8495 the event loop (Bug#7276).

8521 (Fnetwork_interface_list): Allocate in increments of bytes instead
8522 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8523 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8525 (struct ifflag_def): notrailers is smart on OSX.
8526 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8527 Get hardware address with getifaddrs if available.
8529 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8531 * xdisp.c (iterate_out_of_display_property): xassert that
8532 IT->position is set to within IT->object's boundaries. Break from
8533 the loop as soon as EOB is reached; avoids infloops in redisplay
8534 when IT->position is set up wrongly due to some bug.
8535 Set IT->current to match the bidi iterator unconditionally.
8536 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8537 entry. Force push_it to save on the stack the current
8538 buffer/string position, to be restored by pop_it. Fix flags in
8539 the iterator structure wrt the object coming from a display
8540 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8541 properties. (Bug#9284)
8543 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8545 * fontset.c (fontset_get_font_group): Add proper type checks.

8555 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8557 * xdisp.c (forward_to_next_line_start): Allow to use the
8558 no-display-properties-and-no-overlays under bidi display.
8559 Set disp_pos in the bidi iterator to avoid searches for display
8560 properties and overlays.
8562 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8564 * editfns.c (Fset_time_zone_rule): Document relationship with the

8573 restore_point_unwind (Bug#5984).
8575 2011-08-07 Juri Linkov <juri@jurta.org>
8577 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8578 to show the arg `TIME' instead of `TIMEVAL'.
8580 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8582 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a

8584 longlines-mode. (Bug#9254)
8585 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8586 word-wrap under bidirectional display. (Bug#9224)
8588 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8589 is non-zero, even if the data buffer is NULL. Fixes a crash in
8590 vertical-motion with longlines-mode. (Bug#9254)
8592 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8594 * bidi.c <bidi_cache_total_alloc>: Now static.
8595 (bidi_initialize): Initialize bidi_cache_total_alloc.
8597 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8600 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8601 amount allocated this far in `bidi_cache_total_alloc'.
8602 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8603 non-zero, only free the data buffer without restoring the cache
8604 contents. All callers changed.
8606 * dispextern.h (bidi_unshelve_cache): Update prototype.
8608 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8609 (move_it_in_display_line, move_it_to)
8610 (move_it_vertically_backward, move_it_by_lines): Replace the call
8611 to xfree to an equivalent call to bidi_unshelve_cache.
8612 (move_it_in_display_line_to): Fix logic of returning
8613 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8615 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8617 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8618 came from a string character with a `cursor' property. (Bug#9229)

8660 * dispextern.h (struct bidi_it): New member disp_prop_p.
8662 * xdisp.c: Remove one-slot cache of display string positions.
8663 (compute_display_string_pos): Accept an additional argument
8664 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8665 for a display string or property. If found, set DISP_PROP_P
8668 * bidi.c (bidi_fetch_char): Accept an additional argument
8669 DISP_PROP_P, and pass it to compute_display_string_pos.
8670 Only handle text covered by a display string if DISP_PROP_P is returned
8671 non-zero. All callers of bidi_fetch_char changed.
8673 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8675 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8677 2010-12-03 Don March <don@ohspite.net>
8679 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8680 last character M-[char] is translated to ESC [char] (bug#7541).
8682 2011-08-02 Kenichi Handa <handa@m17n.org>
8684 * lisp.h (uniprop_table): Extern it.
8686 * chartab.c (uniprop_table): Make it non-static.
8688 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8690 * xdisp.c (forward_to_next_line_start): Accept additional argument
8691 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8693 (reseat_at_next_visible_line_start): Use the bidi iterator state
8694 returned by forward_to_next_line_start to restore the state of
8695 it->bidi_it after backing up to previous newline. (Bug#9212)
8697 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8699 * regex.c (re_comp): Protoize.
8700 (re_exec): Fix return type.
8701 (regexec): Fix type of `ret'. (Bug#9203)
8703 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8705 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8706 This is needed if max-image-size is a floating-point number.
8708 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8710 * print.c (print_object): Print empty symbol as ##.
8712 * lread.c (read1): Read ## as empty symbol.
8714 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8716 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8717 setting frame foreground color (Bug#9175).
8718 (x_set_background_color): Likewise.
8720 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8721 contents (Bug#9176).
8722 (EmacsTooltip -init): Remove bezels and add shadows to
8725 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8726 or scroll bar (Bug#8470).
8728 * nsfont.m (nsfont_open): Remove assignment to voffset and
8729 unnecessary vars hshink, expand, hd, full_height, min_height.
8730 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8732 * nsterm.h (nsfont_info): Remove voffset field.
8734 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8736 Implement strike-through and overline on NextStep (Bug#8863).
8738 * nsfont.m (nsfont_open): Use underline position provided by font,
8739 instead of hard-coded value of 2.
8740 (nsfont_draw): Call ns_draw_text_decoration instead.
8742 * nsterm.h: Add declaration for ns_draw_text_decoration.
8744 * nsterm.m (ns_draw_text_decoration): New function for drawing
8745 underline, overline, and strike-through.
8746 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8747 ns_draw_text_decoration. Change treatment of cursor drawing to
8748 accommodate underlining, etc.
8750 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8752 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8755 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8757 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8758 Without this fix, if a signal arrives just after memory fills up,
8759 'malloc' might be invoked reentrantly.
8761 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8762 In other words, assume that every image size is allowed, on non-X
8763 hosts. This assumption is probably wrong, but it lets Emacs compile.
8765 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8767 * regex.c (re_iswctype): Convert return values to boolean.
8769 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8771 * xdisp.c (compute_display_string_pos): Don't use cached display
8772 string position if the buffer had its restriction changed.
8775 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8777 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8779 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8781 Integer signedness and overflow and related fixes. (Bug#9079)
8783 * bidi.c: Integer size and overflow fixes.
8784 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8785 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8786 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8787 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8788 (bidi_find_other_level_edge):
8789 Use ptrdiff_t instead of EMACS_INT where either will do.
8790 This works better on 32-bit hosts configured --with-wide-int.
8791 (bidi_cache_ensure_space): Check for size-calculation overflow.
8792 Use % rather than repeated addition, for better worst-case speed.
8793 Don't set bidi_cache_size until after xrealloc returns, because it
8795 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8796 (bidi_cache_ensure_space): Also check that the bidi cache size
8797 does not exceed that of the largest Lisp string or buffer. See Eli
8798 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8800 * alloc.c (__malloc_size_t): Remove.
8801 All uses replaced by size_t. See Andreas Schwab's note
8802 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8804 * image.c: Improve checking for integer overflow.
8805 (check_image_size): Assume that f is nonnull, since
8806 it is always nonnull in practice. This is one less thing to
8807 worry about when checking for integer overflow later.
8808 (x_check_image_size): New function, which checks for integer
8809 overflow issues inside X.
8810 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8811 This removes the need for a memory_full check.
8812 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8813 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8814 (xbm_read_bitmap_data): Change locals back to 'int', since
8815 their values must fit in 'int'.
8816 (xpm_load_image, png_load, tiff_load):
8817 Invoke x_create_x_image_and_pixmap earlier,
8818 to avoid much needless work if the image is too large.
8819 (tiff_load): Treat overly large images as if
8820 x_create_x_image_and_pixmap failed, not as malloc failures.
8821 (gs_load): Use x_check_image_size.
8823 * gtkutil.c: Omit integer casts.
8824 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8825 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8827 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8829 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8830 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8831 would wrongly return t on a 64-bit host.
8833 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8834 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8835 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8836 and therefore cause GCC to emit a bogus diagnostic in some cases.
8838 * image.c: Integer signedness and overflow and related fixes.
8839 This is not an exhaustive set of fixes, but it's time to
8840 record what I've got.
8841 (lookup_pixel_color, check_image_size): Remove redundant decls.
8842 (check_image_size): Don't assume that arbitrary EMACS_INT values
8843 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8844 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8845 (tiff_load, imagemagick_load_image):
8846 Check for overflow in size calculations.
8847 (x_create_x_image_and_pixmap): Remove unnecessary test for
8848 xmalloc returning NULL; that can't happen.
8849 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8850 (xpm_color_bucket): Use better integer hashing function.
8851 (xpm_cache_color): Don't possibly over-allocate memory.
8852 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8853 (gif_memory_source):
8854 Use ptrdiff_t, not int or size_t, to record sizes.
8855 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8856 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8857 either works, as we prefer signed integers.
8858 (tiff_read_from_memory, tiff_write_from_memory):
8859 Return tsize_t, not size_t, since that's what the TIFF API wants.
8860 (tiff_read_from_memory): Don't fail simply because the read would
8861 go past EOF; instead, return a short read.
8862 (tiff_load): Omit no-longer-needed casts.
8863 (Fimagemagick_types): Don't assume size fits into 'int'.
8865 Improve hashing quality when configured --with-wide-int.
8866 * fns.c (hash_string): New function, taken from sxhash_string.
8867 Do not discard information about ASCII character case; this
8868 discarding is no longer needed.
8869 (sxhash-string): Use it. Change sig to match it. Caller changed.
8870 * lisp.h: Declare it.
8871 * lread.c (hash_string): Remove, since we now use fns.c's version.
8872 The fns.c version returns a wider integer if --with-wide-int is
8873 specified, so this should help the quality of the hashing a bit.
8875 * emacs.c: Integer overflow minor fix.
8876 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8877 Define only if GNU_LINUX.
8878 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8880 * dispnew.c: Integer signedness and overflow fixes.
8881 Remove unnecessary forward decls, that were a maintenance hassle.
8882 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8884 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8885 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8886 (prepare_desired_row, line_draw_cost):
8887 Use int, not unsigned, where either works.
8888 (save_current_matrix, restore_current_matrix):
8889 Use ptrdiff_t, not size_t, where either works.
8890 (init_display): Check for overflow more accurately, and without
8891 relying on undefined behavior.
8893 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8894 Remove, replacing with the new symbols in lisp.h. All uses changed.
8895 * fileio.c (make_temp_name):
8896 * filelock.c (lock_file_1, lock_file):
8897 * xdisp.c (message_dolog):
8898 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8899 Use pMd etc. instead.
8900 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8901 replacing the pWIDE etc. symbols removed from editfns.c.
8903 * keyboard.h (num_input_events): Now uintmax_t.
8904 This is (very slightly) less likely to mess up due to wraparound.
8907 * buffer.c: Integer signedness fixes.
8908 (alloc_buffer_text, enlarge_buffer_text):
8909 Use ptrdiff_t rather than size_t when either will do, as we prefer
8912 * alloc.c: Integer signedness and overflow fixes.
8913 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8914 (__malloc_size_t): Default to size_t, not to int.
8915 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8916 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8917 Prefer ptrdiff_t to size_t when either would do, as we prefer
8919 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8920 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8921 Now const. Initialize with values that are in range even if char
8923 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8924 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8925 These functions do the right thing with sizes > 2**32.
8926 (check_depth): Now ptrdiff_t, not int.
8927 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8928 Adjust to new way of storing sizes. Check for size overflow bugs
8930 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8931 slightly wrong anyway, as it missed one instance of
8932 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8933 (refill_memory_reserve): Omit needless cast to size_t.
8934 (mark_object_loop_halt): Mark as externally visible.
8936 * xselect.c: Integer signedness and overflow fixes.
8937 (Fx_register_dnd_atom, x_handle_dnd_message):
8938 Use ptrdiff_t, not size_t, since we prefer signed.
8939 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8940 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8941 x_dnd_atoms_size and x_dnd_atoms_length.
8943 * doprnt.c: Prefer signed to unsigned when either works.
8945 * doprnt.c (doprnt):
8947 * xdisp.c (vmessage):
8948 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8949 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8950 prefer signed arithmetic to avoid comparison confusion.
8951 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8952 but is a bit tricky.
8954 Assume freestanding C89 headers, string.h, stdlib.h.
8955 * data.c, doprnt.c, floatfns.c, print.c:
8956 Include float.h unconditionally.
8957 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8958 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8959 * regex.c: Likewise for stddef.h, string.h.
8960 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8961 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8962 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8963 (STDC_HEADERS): Remove obsolete defines.
8964 * sysdep.c: Include limits.h unconditionally.
8966 Assume support for memcmp, memcpy, memmove, memset.
8967 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8968 * regex.c (memcmp, memcpy):
8969 Remove; we assume C89 now.
8971 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8972 (__malloc_safe_bcopy): Remove; no longer needed.
8974 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8975 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8976 well either way, and we prefer signed to unsigned.
8978 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8980 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8981 closes the connection while we're reading (bug#9182).
8983 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8985 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8986 are specified (Bug#9168).
8988 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8990 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8991 Found by GCC static checking and --with-wide-int on a 32-bit host.
8993 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8995 * xdisp.c (compute_display_string_pos): Fix logic of caching
8996 previous display string position. Initialize cached_prev_pos to
8997 -1. Fixes slow-down at the beginning of a buffer.
8999 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9001 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9002 for attrs[LFACE_FONTSET_INDEX].
9004 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9006 * xml.c (parse_region): Remove unused local
9007 that was recently introduced.
9009 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9011 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9012 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9014 * xdisp.c (move_it_in_display_line_to): Record the best matching
9015 position for TO_CHARPOS while scanning the line, and restore it on
9016 exit if none of the characters scanned was an exact match.
9017 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9018 when exact match is impossible due to invisible text, and the
9019 lines are truncated.
9021 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9023 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9026 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9028 Fix a significant slow-down of cursor motion with C-n, C-p,
9029 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9030 auto-repeat under bidi redisplay in fontified buffers.
9031 * xdisp.c (compute_stop_pos_backwards): New function.
9032 (next_element_from_buffer): Call compute_stop_pos_backwards to
9033 find a suitable prev_stop when we find ourselves before
9035 (reseat): Don't look for prev_stop, as that could mean a very long
9037 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9038 <cached_disp_overlay_modiff>: Cache for last found display string
9040 (compute_display_string_pos): Return the cached position if asked
9041 about the same buffer in the same area of character positions, and
9042 the buffer wasn't changed since the time the display string
9043 position was cached.
9045 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9047 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9048 is an integer, which is important for empty lines. (Bug#9149)
9050 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9052 * frame.c (Fmodify_frame_parameters): In tty case, update the
9053 default face if necessary (Bug#4238).
9055 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9057 * editfns.c (Fstring_to_char): No need to explain what a character
9058 is in the docstring (Bug#6576).
9060 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9062 * xml.c (parse_region): Make sure we always return a tree.
9064 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9066 * xml.c (parse_region): If a document contains only comments,
9069 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9071 * xml.c (make_dom): Return comments, too.
9073 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9076 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9077 and the surrounding thread.
9078 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9079 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9080 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9082 * s/openbsd.h (BROKEN_SIGIO): Define.
9083 * unexelf.c (unexec) [__OpenBSD__]:
9084 Don't update the .mdebug section of the Alpha COFF symbol table.
9086 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9088 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9091 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9093 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9094 This fixes some race conditions on the permissions of any newly
9097 * alloc.c (valid_pointer_p): Use pipe, not open.
9098 This fixes some permissions issues when debugging.
9100 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9101 If fchown fails to set both uid and gid, try to set just gid,
9102 as that is sometimes allowed. Adjust the file's mode to eliminate
9103 setuid or setgid bits that are inappropriate if fchown fails.
9105 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9107 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9108 to compare Lisp_Objects.
9109 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9110 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9111 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9113 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9115 * lread.c (read_integer): Unread even EOF character.
9116 (read1): Likewise. Properly record start position of symbol.
9118 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9119 symbol character follows.
9121 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9123 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9124 This works around a problem with the previous change to Fcopy_file.
9125 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9126 and without this change, GCC might complain about discarding
9127 fchown's return value.

9225 the iterator is before prev_stop.
9226 (init_iterator): Initialize bidi_p from the default value of

9744 Random fixes. E.g., (random) never returned negative values.
9745 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9746 subseconds part to the entropy, as that's a bit more random.
9747 Prefer signed to unsigned, since the signedness doesn't matter and
9748 in general we prefer signed. When given a limit, use a
9749 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9750 latter isn't right if USE_2_TAGS_FOR_INTS.
9751 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9752 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9765 This is more efficient than Ffile_directory_p and avoids a minor race.
9767 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9769 * buffer.c (Foverlay_put): Say what the return value is
9772 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9775 (barf_or_query_if_file_exists): Make the "File is a directory"
9776 error be more correct.
9778 * fns.c (Frequire): Remove the mention of the .gz files, since
9779 that's installation-specific, but keep the mention of
9780 `get-load-suffixes'.
9782 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9784 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9795 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9897 * eval.c (struct backtrace): Simplify and port the data structure.
9898 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9899 signed bit field, as this assumption is not portable and it makes
9900 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9901 "char debug_on_exit : 1" as this is not portable either; instead,
9902 use the portable "unsigned int debug_on_exit : 1". Remove unused
9903 member evalargs. Remove obsolete comments about cc bombing out.

10063 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
10065 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
10067 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10069 Integer and buffer overflow fixes (Bug#8873).
10071 * print.c (printchar, strout): Check for string overflow.
10072 (PRINTPREPARE, printchar, strout):
10073 Don't set size unless allocation succeeds.
10075 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10076 for sizes. Check for string overflow more accurately.
10077 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10079 * macros.c: Integer and buffer overflow fixes.
10080 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10081 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10082 Use ptrdiff_t, not int, for sizes.
10083 Don't increment bufsize until after realloc succeeds.
10084 Check for size-calculation overflow.
10085 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10087 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10089 * lread.c: Integer overflow fixes.
10090 (read_integer): Radix is now EMACS_INT, not int,
10091 to improve quality of diagnostics for out-of-range radices.
10092 Calculate buffer size correctly for out-of-range radices.
10093 (read1): Check for integer overflow in radices, and in
10094 read-circle numbers.
10095 (read_escape): Avoid int overflow.
10096 (Fload, openp, read_buffer_size, read1)
10097 (substitute_object_recurse, read_vector, read_list, map_obarray):
10098 Use ptrdiff_t, not int, for sizes.
10099 (read1): Use EMACS_INT, not int, for sizes.
10100 Check for size overflow.
10102 * image.c (cache_image): Check for size arithmetic overflow.
10104 * lread.c: Integer overflow issues.
10105 (saved_doc_string_size, saved_doc_string_length)
10106 (prev_saved_doc_string_size, prev_saved_doc_string_length):
10107 Now ptrdiff_t, not int.

10109 out-of-range doc string lengths.
10110 (read_list): Don't assume file position fits in int.
10111 (read_escape): Check for hex character overflow.
10113 2011-06-22 Leo Liu <sdl.web@gmail.com>
10115 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10116 Move to minibuffer.el.
10118 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10120 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10121 The following patches are for when GLYPH_DEBUG && !XASSERT.
10122 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10123 * dispnew.c (flush_stdout):
10124 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10125 Mark as externally visible.
10126 * dispnew.c (check_window_matrix_pointers): Now static.
10127 * dispnew.c (window_to_frame_vpos):
10128 * xfns.c (unwind_create_frame):
10129 * xterm.c (x_check_font): Remove unused local.
10130 * scroll.c (CHECK_BOUNDS):
10131 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10132 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10133 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10134 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10135 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10137 (debug_method_add): Use va_list and vsprintf rather than relying
10138 on undefined behavior with wrong number of arguments.
10139 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10140 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10141 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10142 since we're not interested in debugging glyphs with old libraries.
10143 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10144 GCC 4.6.0's static checking.
10146 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10148 Integer overflow and signedness fixes (Bug#8873).

10157 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10158 (x_create_bitmap_from_xpm_data):
10159 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10160 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10162 * xfaces.c (load_pixmap):
10163 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10164 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10165 (.bitmaps_last, struct x_output.icon_bitmap):
10166 Use ptrdiff_t, not int, for bitmap indexes.
10167 (x_allocate_bitmap_record): Check for size overflow.
10168 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10170 Use ptrdiff_t, not int, for overlay counts.
10171 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10172 * editfns.c (overlays_around, get_pos_property):
10173 * textprop.c (get_char_property_and_overlay):
10174 * xdisp.c (next_overlay_change, note_mouse_highlight):
10175 * xfaces.c (face_at_buffer_position):
10176 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10177 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10178 (Fnext_overlay_change, Fprevious_overlay_change)
10179 (mouse_face_overlay_overlaps, Foverlays_in):
10180 Use ptrdiff_t, not int, for sizes.
10181 (overlays_at, overlays_in): Check for size-calculation overflow.
10183 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10185 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10186 (x_session_initialize): Do not assume string length fits in int.
10188 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10189 This is unlikely, but can occur if DPI is outlandish.
10191 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10192 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10194 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10195 * xrdb.c (magic_file_p, search_magic_path):
10196 Omit last arg SUFFIX; it was always 0. All callers changed.
10197 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10199 * xfont.c (xfont_match): Avoid need for strlen.
10201 * xfns.c: Don't assume strlen fits in int.
10202 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10204 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10205 not unsigned long, as we prefer signed integers. All callers changed.
10206 Detect integer overflow in repeat count.
10207 (message_dolog): Don't assume print length fits in 39 bytes.
10208 (display_mode_element): Don't assume strlen fits in int.
10210 * termcap.c: Don't assume sizes fit in int and never overflow.
10211 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10212 (gobble_line): Check for size-calculation overflow.
10214 * minibuf.c (Fread_buffer):
10215 * lread.c (intern, intern_c_string):
10216 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10217 Don't assume string length fits in int.
10219 * keyboard.c (parse_tool_bar_item):
10220 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10222 * font.c: Don't assume string length fits in int.
10223 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10224 Use ptrdiff_t, not int.
10225 (font_intern_prop): Don't assume string length fits in int.
10226 Don't assume integer property fits in fixnum.
10227 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10229 * filelock.c: Fix some buffer overrun and integer overflow issues.
10230 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10231 Reformulate so as not to need the command string.
10232 Invoke gzip -cd rather than gunzip, as it's more portable.
10233 (lock_info_type, lock_file_1, lock_file):
10234 Don't assume pid_t and time_t fit in unsigned long.
10235 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10236 (current_lock_owner): Prefer signed type for sizes.
10237 Use memcpy, not strncpy, where memcpy is what is really wanted.
10238 Don't assume (via atoi) that time_t and pid_t fit in int.
10239 Check for time_t and/or pid_t out of range, e.g., via a network share.
10240 Don't alloca where an auto var works fine.
10242 * fileio.c: Fix some integer overflow issues.
10243 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10244 Don't assume string length fits in int.
10245 (directory_file_name): Don't assume string length fits in long.
10246 (make_temp_name): Don't assume pid fits in int, or that its print
10247 length is less than 20.
10249 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10251 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10253 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10255 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10256 We prefer signed integers, even for size calculations.
10258 * emacs.c: Don't assume string length fits in 'int'.
10259 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10260 (main): Don't invoke strlen when not needed.
10262 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10263 (XD_DEBUG_MESSAGE): Don't waste a byte.
10265 * callproc.c (getenv_internal_1, getenv_internal)
10266 (Fgetenv_internal):
10267 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10269 * lread.c (invalid_syntax): Omit length argument.
10270 All uses changed. This doesn't fix a bug, but it simplifies the
10271 code away from its former Hollerith-constant appearance, and it's
10272 one less 'int' to worry about when looking at integer-overflow issues.
10273 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10275 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10276 This didn't break anything, but it didn't help either.
10277 It's confusing to put a bogus integer in a place where the actual
10278 value does not matter.
10279 (LIST_END_P): Remove unused macro and its bogus comment.
10280 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10282 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10283 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10285 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10286 We prefer signed types, and the value cannot exceed the EMACS_INT
10287 range anyway (because otherwise the length would not be representable).
10288 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10289 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10290 This avoids a GCC warning when WIDE_EMACS_INT.
10292 * indent.c (sane_tab_width): New function.
10293 (current_column, scan_for_column, Findent_to, position_indentation)
10294 (compute_motion): Use it. This is just for clarity.
10295 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10297 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10299 * lisp.h (lint_assume): New macro.
10300 * composite.c (composition_gstring_put_cache):
10301 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10303 * editfns.c, insdel.c:
10304 Omit unnecessary forward decls, to simplify future changes.
10306 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10308 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10310 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10311 Use much-faster test for byte-length change.
10312 Don't assume string byte-length fits in 'int'.
10313 Check that character arg fits in 'int'.
10314 (mapcar1): Declare byte as byte, for clarity.
10316 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10318 * fns.c (concat): Catch string overflow earlier.
10319 Do not rely on integer wraparound.
10321 * dispextern.h (struct it.overlay_strings_charpos)
10322 (struct it.selective): Now EMACS_INT, not int.
10323 * xdisp.c (forward_to_next_line_start)
10324 (back_to_previous_visible_line_start)
10325 (reseat_at_next_visible_line_start, next_element_from_buffer):
10326 Don't arbitrarily truncate the value of 'selective' to int.
10328 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10330 * composite.c: Don't truncate sizes to 'int'.
10331 (composition_gstring_p, composition_reseat_it)
10332 (composition_adjust_point): Use EMACS_INT, not int.
10333 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10334 not EMACS_UINT, for indexes.
10336 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10338 * buffer.c: Include <verify.h>.
10339 (struct sortvec.priority, struct sortstr.priority):
10340 Now EMACS_INT, not int.
10341 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10342 (struct sortstr.size, record_overlay_string)
10343 (struct sortstrlist.size, struct sortlist.used):
10344 Don't truncate size to int.
10345 (record_overlay_string): Check for size-calculation overflow.
10346 (init_buffer_once): Check at compile-time, not run-time.
10348 2011-06-22 Jim Meyering <meyering@redhat.com>
10350 Don't leak an XBM-image-sized buffer
10351 * image.c (xbm_load): Free the image buffer after using it.
10353 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10356 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10357 that Sun C diagnosed.
10358 * fns.c (secure_hash): Fix pointer signedness issue.
10359 * intervals.c (static_offset_intervals): New function.
10360 (offset_intervals): Use it.
10362 2011-06-21 Leo Liu <sdl.web@gmail.com>
10365 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10368 * fns.c (secure_hash): Rename from crypto_hash_function and change
10369 the first arg to accept symbols.
10370 (Fsecure_hash): New primitive.
10371 (syms_of_fns): New symbols.
10373 2011-06-20 Deniz Dogan <deniz@dogan.se>
10375 * process.c (Fset_process_buffer): Clarify return value in
10378 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10380 * dispnew.c (add_window_display_history): Use BVAR.
10382 * xdisp.c (debug_method_add): Use BVAR.
10383 (check_window_end, dump_glyph_matrix, dump_glyph)
10384 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10386 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10389 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10390 check till after the cache is created in init_frame_faces.
10392 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10394 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10396 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10398 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10399 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10400 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10402 Improve buffer-overflow checking (Bug#8873).
10403 * fileio.c (Finsert_file_contents):
10404 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10405 Remove the old (too-loose) buffer overflow checks.
10406 They weren't needed, since make_gap checks for buffer overflow.
10407 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10408 The old code merely checked for Emacs fixnum overflow, and relied
10409 on undefined (wraparound) behavior. The new code avoids undefined
10410 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10412 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10413 Tune. Don't use wider integers than needed. Don't use alloca.
10414 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10416 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10418 * insdel.c, lisp.h (buffer_overflow): New function.
10419 (insert_from_buffer_1, replace_range, replace_range_2):
10420 * insdel.c (make_gap_larger):
10421 * editfns.c (Finsert_char):
10422 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10424 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10426 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10428 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10430 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10431 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10433 * fileio.c: Don't assume EMACS_INT fits in off_t.
10434 (emacs_lseek): New static function.
10435 (Finsert_file_contents, Fwrite_region): Use it.
10436 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10438 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10440 * fns.c: Don't overflow int when computing a list length.
10441 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10442 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10443 truncation on 64-bit hosts. Check for QUIT every
10444 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10445 faster and is responsive enough.
10446 (Flength): Report an error instead of overflowing an integer.
10447 (Fsafe_length): Return a float if the value is not representable
10448 as a fixnum. This shouldn't happen except in contrived situations.
10449 (Fnthcdr, Fsort): Don't assume list length fits in int.
10450 (Fcopy_sequence): Don't assume vector length fits in int.
10452 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10453 (header_size, word_size): New constants.
10454 (allocate_vectorlike): Don't check size overflow here.
10455 (allocate_vector): Check it here instead, since this is the only
10456 caller of allocate_vectorlike that could cause overflow.
10457 Check that the new vector's length is representable as a fixnum.
10459 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10460 The previous code was bogus. For example, next_almost_prime (32)
10461 returned 39, which is undesirable as it is a multiple of 3; and
10462 next_almost_prime (24) returned 25, which is a multiple of 5 so
10463 why was the code bothering to check for multiples of 7?
10465 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10467 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10469 Variadic C functions now count arguments with ptrdiff_t.
10470 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10471 Back then I didn't know that the Emacs coding style prefers signed int.
10472 Also, in the meantime I found a few more instances where arguments
10473 were being counted with int, which may truncate counts on 64-bit
10474 machines, or EMACS_INT, which may be unnecessarily wide.
10475 * lisp.h (struct Lisp_Subr.function.aMANY)
10476 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10477 Arg counts are now ptrdiff_t, not size_t.
10478 All variadic functions and their callers changed accordingly.
10479 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10480 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10481 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10482 * callint.c (Fcall_interactively): Check arg count for overflow,
10483 to avoid potential buffer overrun. Use signed char, not 'int',
10484 for 'varies' array, so that we needn't bother to check its size
10485 calculation for overflow.
10486 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10487 * eval.c (apply_lambda):
10488 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10489 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10490 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10492 * callint.c (Fcall_interactively): Don't use index var as event count.
10494 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10495 * mem-limits.h (SIZE): Remove; no longer used.
10497 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10499 Remove unnecessary casts.
10500 * xterm.c (x_term_init):
10501 * xfns.c (x_set_border_pixel):
10502 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10503 These aren't needed now that we assume ANSI C.
10505 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10506 It's more likely to cause problems (due to unsigned overflow)
10509 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10511 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10513 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10515 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10517 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10519 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10521 GLYPH_CODE_FACE returns EMACS_INT, not int.
10522 * dispextern.h (merge_faces):
10523 * xfaces.c (merge_faces):
10524 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10525 Don't assume EMACS_INT fits in int.
10527 * character.h (CHAR_VALID_P): Remove unused parameter.
10528 * fontset.c, lisp.h, xdisp.c: All uses changed.
10530 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10532 * fns.c (concat): Minor tuning based on overflow analysis.
10533 This doesn't fix any bugs. Use int to hold character, instead
10534 of constantly refetching from Emacs object. Use XFASTINT, not
10535 XINT, for value known to be a character. Don't bother comparing
10536 a single byte to 0400, as it's always less.
10538 * floatfns.c (Fexpt):
10539 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10541 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10544 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10546 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10547 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10548 incorrectly succeed when S was a string, because 4294967386 was
10549 truncated before it was used.
10551 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10552 Otherwise, an out-of-range integer could cause undefined behavior
10555 * composite.c: Use int, not EMACS_INT, for characters.
10556 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10557 EMACS_INT, for values that are known to be in character range.
10558 This doesn't fix any bugs but is the usual style inside Emacs and
10559 may generate better code on 32-bit machines.
10561 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10562 This is for reasons similar to the recent CHAR_STRING fix.
10563 * charset.c (Fencode_char): Check that character arg is actually
10564 a character. Pass an int to ENCODE_CHAR.
10565 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10566 wider than 'int', as a compile-time check to prevent future regressions
10569 * character.c (char_string): Remove unnecessary casts.
10571 Make sure a 64-bit char is never passed to CHAR_STRING.
10572 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10573 by silently ignoring the top 32 bits, allowing some values
10574 that were far too large to be valid characters.
10575 * character.h: Include <verify.h>.
10576 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10577 arguments are no wider than unsigned, as a compile-time check
10578 to prevent future regressions in this area.
10580 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10581 (Fsubst_char_in_region):
10583 * xdisp.c (decode_mode_spec_coding):
10584 Adjust to CHAR_STRING's new requirement.
10585 * editfns.c (Finsert_char, Fsubst_char_in_region):
10586 * fns.c (concat): Check that character args are actually
10587 characters. Without this test, these functions did the wrong
10588 thing with wildly out-of-range values on 64-bit hosts.
10590 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10591 These casts should not be needed on 32-bit hosts, either.
10592 * keyboard.c (read_char):
10593 * lread.c (Fload): Remove casts to unsigned.
10595 * lisp.h (UNSIGNED_CMP): New macro.
10596 This fixes comparison bugs on 64-bit hosts.
10597 (ASCII_CHAR_P): Use it.
10598 * casefiddle.c (casify_object):
10599 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10600 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10601 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10602 * dispextern.h (FACE_FROM_ID):
10603 * keyboard.c (read_char): Use UNSIGNED_CMP.
10605 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10606 not to EMACS_INT, to avoid GCC warning.
10608 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10610 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10611 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10612 isn't needed on 32-bit machines.
10614 * buffer.c (Fgenerate_new_buffer_name):
10615 Use EMACS_INT for count, not int.
10616 (advance_to_char_boundary): Return EMACS_INT, not int.
10618 * data.c (Qcompiled_function): Now static.
10620 * window.c (window_body_lines): Now static.
10622 * image.c (gif_load): Rename local to avoid shadowing.
10624 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10625 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10626 * alloc.c (make_save_value): Integer argument is now of type
10627 ptrdiff_t, not int.
10628 (mark_object): Use ptrdiff_t, not int.
10629 * lisp.h (pD): New macro.
10630 * print.c (print_object): Use it.
10632 * alloc.c: Use EMACS_INT, not int, to count objects.
10633 (total_conses, total_markers, total_symbols, total_vector_size)
10634 (total_free_conses, total_free_markers, total_free_symbols)
10635 (total_free_floats, total_floats, total_free_intervals)
10636 (total_intervals, total_strings, total_free_strings):
10637 Now EMACS_INT, not int. All uses changed.
10638 (Fgarbage_collect): Compute overall total using a double, so that
10639 integer overflow is less likely to be a problem. Check for overflow
10640 when converting back to an integer.
10641 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10642 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10643 These were 'int' variables that could overflow on 64-bit hosts;
10644 they were never used, so remove them instead of repairing them.
10645 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10646 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10647 Previously, this ceilinged at INT_MAX, but that doesn't work on
10649 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10651 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10652 (allocate_vectorlike): Check for ptrdiff_t overflow.
10653 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10654 when a (possibly-narrower) signed value would do just as well.
10655 We prefer using signed arithmetic, to avoid comparison confusion.
10657 * alloc.c: Catch some string size overflows that we were missing.
10658 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10659 for convenience in STRING_BYTES_MAX.
10660 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10661 The definition here is exact; the one in lisp.h was approximate.
10662 (allocate_string_data): Check for string overflow. This catches
10663 some instances we weren't catching before. Also, it catches
10664 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10665 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10666 and ptrdiff_t and EMACS_INT are both 64 bits.
10668 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10669 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10670 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10672 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10674 * alloc.c (Fmake_string): Check for out-of-range init.
10676 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10678 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10680 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10682 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10683 xg_get_default_scrollbar_width.
10685 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10686 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10687 (style_changed_cb): Call update_theme_scrollbar_width and call
10688 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10689 all frames (Bug#8505).
10690 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10691 Call gtk_window_set_resizable if HAVE_GTK3.

10693 and height if HAVE_GTK3 (Bug#8505).
10694 (scroll_bar_width_for_theme): New variable.
10695 (update_theme_scrollbar_width): New function.
10696 (xg_get_default_scrollbar_width): Move code to
10697 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10698 (xg_initialize): Call update_theme_scrollbar_width.
10700 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10702 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10704 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10706 * frame.c (make_frame): Call other_buffer_safely instead of
10709 * window.c (temp_output_buffer_show): Call display_buffer with
10710 second argument Vtemp_buffer_show_specifiers and reset latter
10711 immediately after the call.
10712 (Vtemp_buffer_show_specifiers): New variable.
10713 (auto_window_vscroll_p, next_screen_context_lines)
10714 (Vscroll_preserve_screen_position): Remove leading asterisks from

10721 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10722 (record_buffer): Remove unused local.
10723 * frame.c (other_visible_frames, frame_buffer_list): Now static.

10735 * widgetprv.h (emacsFrameClassRec): Remove decl.
10736 * window.c (delete_deletable_window): Now returns void, since it
10737 wasn't returning anything.
10738 (compare_window_configurations): Remove unused locals.
10739 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10740 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.

10755 (syms_of_image): Use DEFSYM. New symbol `delay'.
10757 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10759 * window.c (delete_deletable_window): Re-add.
10760 (Fset_window_configuration): Rewrite to handle dead buffers and
10761 consequently deletable windows.
10762 (window_tree, Fwindow_tree): Remove. Supply functionality in
10764 (compare_window_configurations): Simplify code.
10766 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>

10782 buffer list implementation.
10783 (other_buffer_safely): New function.

10895 window_min_size_1, window_min_size_2, window_min_size,
10896 size_window, window_fixed_size_p, enlarge_window, delete_window.
10897 Remove static from declaration of Qdelete_window, it's
10898 temporarily needed by Fbury_buffer.
10899 (replace_window): Don't assign orig_top_line and
10901 (Fdelete_window, delete_window): Remove. Window deletion is

10903 (window_loop): Remove DELETE_OTHER_WINDOWS case.
10904 Replace Fdelete_window calls with calls to Qdelete_window.
10905 (Fdelete_other_windows): Remove. Deleting other windows is

11278 value of a `display' property is a "replacing spec".
11279 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11280 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11310 * gnutls.c: Use Emacs's memory allocators.
11311 Without this change, the gnutls library would invoke malloc etc.
11312 directly, which causes problems on non-SYNC_INPUT hosts, and which
11313 runs afoul of improving memory_full behavior. (Bug#8761)
11314 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11315 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11316 xfree instead of the default malloc, realloc, free.
11317 (Fgnutls_boot): No need to check for memory allocation failure,
11318 since xmalloc does that for us.

11347 need to be updated by these changes.
11348 * fns.c (make_hash_table, maybe_resize_hash_table):
11349 Check for integer overflow with large hash tables.
11350 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11351 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11352 (SXHASH_REDUCE): New macro.
11353 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11354 Use it instead of discarding useful hash info with large hash values.
11355 (sxhash_float): New function.
11356 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11357 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11358 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11359 Rewrite to use FIXNUM_BITS, as this simplifies things.
11360 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11361 Adjust signatures to match updated version of code.
11362 (consing_since_gc): Now EMACS_INT, since a single hash table can
11363 use more than INT_MAX bytes.
11365 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11367 Make it possible to build with GCC-4.6+ -O2 -flto.
11369 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11371 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11373 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11374 Call minibuffer-inactive-mode.
11376 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11378 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11379 Update dependencies.
11381 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11383 * data.c (init_data): Remove code for UTS, this system is not
11386 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11388 Don't force ./temacs to start in terminal mode.
11390 * frame.c (make_initial_frame): Initialize faces in all cases, not
11391 only when CANNOT_DUMP is defined.
11392 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11394 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11396 * dispnew.c (add_window_display_history): Use const for the string
11397 pointer. Remove declaration, not needed.
11399 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11401 Use 'inline', not 'INLINE'.
11402 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11403 * alloc.c, fontset.c (INLINE): Remove.
11404 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11405 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11406 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11407 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11408 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11410 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11412 Make it possible to run ./temacs.
11414 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11415 syms_of_callproc does the same thing. Remove test for
11416 "initialized", do it in the caller.
11417 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11419 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11421 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11422 (read_minibuf): Use get_minibuffer.
11423 (syms_of_minibuf): Use DEFSYM.
11424 (Qmetadata): New var.
11425 * data.c (Qbuffer): Don't make it static.
11426 (syms_of_data): Use DEFSYM.
11428 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11430 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11431 (CCL_CODE_MIN): New macro.
11433 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11435 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11437 * eval.c (Qdebug): Now static.
11438 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11439 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11440 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11442 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11444 * image.c: Various fixes to ImageMagick code comments.
11445 (Fimagemagick_types): Doc fix.
11447 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11449 Minor fixes prompted by GCC 4.6.0 warnings.
11451 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11453 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11454 (x_clipboard_manager_save_all): Move extern decl to ...
11455 * xterm.h: ... here, so that it can be checked for consistency.
11457 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11459 * xselect.c (x_clipboard_manager_save_frame)
11460 (x_clipboard_manager_save_all): New functions.
11461 (Fx_clipboard_manager_save): Lisp function deleted.
11463 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11464 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11466 * xterm.h: Update prototype.
11468 2011-05-28 William Xu <william.xwl@gmail.com>
11470 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11471 exiting (Bug#8239).
11473 2011-05-28 Jim Meyering <meyering@redhat.com>
11475 Avoid a sign-extension bug in crypto_hash_function.
11476 * fns.c (to_uchar): Define.
11477 (crypto_hash_function): Use it to convert some newly-signed
11478 variables to unsigned, to avoid sign-extension bugs. For example,
11479 without this change, (md5 "truc") would evaluate to
11480 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11481 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11482 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11484 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11486 Integer overflow fixes.
11488 * dbusbind.c: Serial number integer overflow fixes.
11489 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11490 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11491 to hold a serial number that is too large for a fixnum.
11492 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11493 Check for serial numbers out of range. Decode any serial number
11494 that was so large that it became a float. (Bug#8722)
11496 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11497 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11498 Use XFASTINT rather than XUINT when numbers are nonnegative.
11499 (xd_append_arg, Fdbus_method_return_internal):
11500 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11501 arguments, check that Lisp number is nonnegative, rather than
11502 silently wrapping negative numbers around. (Bug#8722)
11503 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11506 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11508 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11510 ccl: Add integer overflow checks.
11511 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11512 (IN_INT_RANGE): New macros.
11513 (ccl_driver): Use them to check for integer overflow when
11514 decoding a CCL program. Many of the new checks are whether XINT (x)
11515 fits in int; it doesn't always, on 64-bit hosts. The new version
11516 doesn't catch all possible integer overflows, but it's an
11517 improvement. (Bug#8719)
11519 * alloc.c (make_event_array): Use XINT, not XUINT.
11520 There's no need for unsigned here.
11522 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11523 This follows up to the 2011-05-06 change that substituted uintptr_t
11524 for EMACS_INT. This case wasn't caught back then.
11526 Rework Fformat to avoid integer overflow issues.
11527 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11528 now (part of C89). Include <verify.h>.
11529 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11530 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11531 (Fformat): Avoid the prepass trying to compute sizes; it was only
11532 approximate and thus did not catch overflow reliably. Instead, walk
11533 through the format just once, formatting and computing sizes as we go,
11534 checking for integer overflow at every step, and allocating a larger
11535 buffer as needed. Keep track separately whether the format is
11536 multibyte. Keep only the most-recently calculated precision, rather
11537 than them all. Record whether each argument has been converted to
11538 string. Use EMACS_INT, not int, for byte and char and arg counts.
11539 Support field widths and precisions larger than INT_MAX. Avoid
11540 sprintf's undefined behavior with conversion specifications such as %#d
11541 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11542 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11543 formatting out-of-range floating point numbers with int
11544 formats. (Bug#8668)
11546 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11548 * data.c: Avoid integer truncation in expressions involving floats.
11549 * data.c: Include <intprops.h>.
11550 (arith_driver): When there's an integer overflow in an expression
11551 involving floating point, convert the integers to floating point
11552 so that the resulting value does not suffer from catastrophic
11553 integer truncation. For example, on a 64-bit host (* 4
11554 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11555 Do not rely on undefined behavior after integer overflow.
11557 merge count_size_as_multibyte, parse_str_to_multibyte
11558 * character.c, character.h (count_size_as_multibyte):
11559 Rename from parse_str_to_multibyte; all uses changed.
11560 Check for integer overflow.
11561 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11562 since it's now a duplicate of the other. This is more of
11563 a character than a buffer op, so better that it's in character.c.
11564 * fns.c, print.c: Adjust to above changes.
11566 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11568 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11570 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11572 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11573 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11574 (x_clipboard_manager_save): Now static.
11575 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11577 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11578 (crypto_hash_function): Now static.
11579 Fix pointer signedness problems. Avoid unnecessary initializations.
11581 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11583 * termhooks.h (Vselection_alist): Make it terminal-local.
11585 * terminal.c (create_terminal): Initialize it.
11587 * xselect.c: Support for clipboard managers.
11588 (Vselection_alist): Move to termhooks.h as terminal-local var.
11589 (LOCAL_SELECTION): New macro.
11590 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11591 (symbol_to_x_atom): Remove gratuitous arg.
11592 (x_handle_selection_request, lisp_data_to_selection_data)
11593 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11594 (x_own_selection, x_get_local_selection, x_convert_selection):
11595 New arg, specifying work frame. Use terminal-local Vselection_alist.
11596 (some_frame_on_display): Delete unused function.
11597 (Fx_own_selection_internal, Fx_get_selection_internal)
11598 (Fx_disown_selection_internal, Fx_selection_owner_p)
11599 (Fx_selection_exists_p): New optional frame arg.
11600 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11601 (x_handle_selection_clear): Don't treat other terminals with the
11602 same keyboard specially. Use the terminal-local Vselection_alist.
11603 (x_clear_frame_selections): Use Frun_hook_with_args.
11605 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11607 * xterm.h: Add support for those atoms.
11609 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11611 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11612 (converted_selections, conversion_fail_tag): New global variables.
11613 (x_selection_request_lisp_error): Free the above.
11614 (x_get_local_selection): Remove unnecessary code.
11615 (x_reply_selection_request): Args changed; handle arbitrary array
11616 of converted selections stored in converted_selections.
11617 Separate the XChangeProperty and SelectionNotify steps.
11618 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11619 (x_convert_selection): New function.
11620 (x_handle_selection_event): Simplify.
11621 (x_get_foreign_selection): Don't ignore incoming requests while
11622 waiting for an answer; this will fail when we implement
11623 SAVE_TARGETS, and seems unnecessary anyway.
11624 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11625 (Vx_sent_selection_functions): Doc fix.
11627 2011-05-26 Leo Liu <sdl.web@gmail.com>
11629 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11631 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11633 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11635 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11636 for fringe update if it has periodic bitmap.
11637 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11638 and fringe_bitmap_periodic_p.
11640 * fringe.c (get_fringe_bitmap_data): New function.
11641 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11642 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11643 row. Mark glyph row for fringe update if periodicity changed.
11645 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11646 for fringe update unless it has periodic bitmap.
11648 2011-05-25 Kenichi Handa <handa@m17n.org>
11650 * xdisp.c (get_next_display_element): Set correct it->face_id for
11651 a static composition.
11653 2011-05-24 Leo Liu <sdl.web@gmail.com>
11656 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11658 * fns.c (crypto_hash_function, Fsha1): New function.
11659 (Fmd5): Use crypto_hash_function.
11660 (syms_of_fns): Add Ssha1.
11662 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11664 * gnutls.c: Remove unused macros.
11665 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11666 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11667 Remove macros that are defined and never used.
11668 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11670 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11672 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11673 (Fx_get_selection_internal): Minor cleanup.
11674 (Fx_own_selection_internal): Rename arguments for consistency with
11677 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11679 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11681 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11683 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11685 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11687 * dispnew.c (scrolling_window): Don't exclude the case that the
11688 last enabled row in the desired matrix touches the bottom boundary.
11690 2011-05-21 Glenn Morris <rgm@gnu.org>
11692 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11693 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11694 and add some more files.
11696 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11698 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11699 report_file_error introduced by the change from 2011-05-07.
11701 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11703 * systime.h (Time): Define only if emacs is defined.
11704 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11705 where the include path doesn't have X11/X.h by default. See
11706 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11708 2011-05-20 Kenichi Handa <handa@m17n.org>
11710 * composite.c (find_automatic_composition): Fix previous change.
11712 2011-05-20 Glenn Morris <rgm@gnu.org>
11714 * lisp.mk: New file, split from Makefile.in.
11715 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11716 (shortlisp): Remove.
11717 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11719 2011-05-19 Glenn Morris <rgm@gnu.org>
11721 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11722 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11723 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11724 (lisp): Set the order to that of loadup.el.
11725 (shortlisp): Make it a copy of $lisp.
11726 (SOME_MACHINE_LISP): Remove.
11727 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11728 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11730 2011-05-18 Kenichi Handa <handa@m17n.org>
11732 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11733 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11734 (find_automatic_composition): Mostly rewrite for efficiency.
11736 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11738 * makefile.w32-in: Update dependencies.
11740 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11742 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11743 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11745 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11747 Fix some integer overflow issues, such as string length overflow.
11749 * insdel.c (count_size_as_multibyte): Check for string overflow.
11751 * character.c (lisp_string_width): Check for string overflow.
11752 Use EMACS_INT, not int, for string indexes and lengths; in
11753 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11754 the resulting string length overflows an EMACS_INT; instead,
11755 report a string overflow if no precision given. When checking for
11756 precision exhaustion, use a check that cannot possibly have
11757 integer overflow. (Bug#8675)
11758 * character.h (lisp_string_width): Adjust to new signature.
11760 * alloc.c (string_overflow): New function.
11761 (Fmake_string): Use it. This doesn't change behavior, but saves
11762 a few bytes and will simplify future changes.
11763 * character.c (string_escape_byte8): Likewise.
11764 * lisp.h (string_overflow): New decl.
11766 Fixups, following up to the user-interface timestamp change.
11767 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11768 for UI timestamps, instead of unsigned long.
11769 * msdos.c (mouse_get_pos): Likewise.
11770 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11771 * w32gui.h (Time): Define by including "systime.h" rather than by
11772 declaring it ourselves. (Bug#8664)
11774 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11775 * image.c (clear_image_cache): Likewise.
11777 * term.c (term_mouse_position): Don't assume time_t wraparound.
11779 Be more systematic about user-interface timestamps.
11780 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11781 and sometimes 'EMACS_UINT', to represent these timestamps.
11782 This change causes it to use 'Time' uniformly, as that's what X uses.
11783 This makes the code easier to follow, and makes it easier to catch
11784 integer overflow bugs such as Bug#8664.
11785 * frame.c (Fmouse_position, Fmouse_pixel_position):
11786 Use Time, not unsigned long, for user-interface timestamps.
11787 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11788 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11789 * keyboard.h (last_event_timestamp): Likewise.
11790 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11791 * menu.h (xmenu_show): Likewise.
11792 * term.c (term_mouse_position): Likewise.
11793 * termhooks.h (struct input_event.timestamp): Likewise.
11794 (struct terminal.mouse_position_hook): Likewise.
11795 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11796 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11797 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11798 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11799 what it was before.
11800 * menu.h, termhooks.h: Include "systime.h", for Time.
11802 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11803 Don't assume that the difference between two unsigned long values
11804 can fit into an integer. At this point, we know button_down_time
11805 <= event->timestamp, so the difference must be nonnegative, so
11806 there's no need to cast the result if double-click-time is
11807 nonnegative, as it should be; check that it's nonnegative, just in
11808 case. This bug is triggered when events are more than 2**31 ms
11809 apart (about 25 days). (Bug#8664)
11811 * xselect.c (last_event_timestamp): Remove duplicate decl.
11812 (x_own_selection): Remove needless cast to unsigned long.
11814 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11815 that always fit in int. Use a sentinel instead of a counter, to
11816 avoid a temp and to allay GCC's concerns about possible int overflow.
11817 * frame.h (struct frame): Use int for menu_bar_items_used
11818 instead of EMACS_INT, since it always fits in int.
11820 * menu.c (grow_menu_items): Check for int overflow.
11822 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11824 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11825 Before, the code was not consistent. These values cannot exceed
11826 2**31 - 1 so there's no need to make them unsigned.
11827 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11828 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11829 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11831 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11833 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11834 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11835 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11836 presumably because the widths might not match.
11838 * window.c (size_window): Avoid needless test at loop start.
11840 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11842 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11844 2011-05-12 Drew Adams <drew.adams@oracle.com>
11846 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11848 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11850 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11851 `width' to `bar_area_x' and `bar_area_width', respectively.
11852 (x_scroll_run): Take account of fringe background extension.
11854 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11855 Rename local vars `left' and `width' to `bar_area_x' and
11856 `bar_area_width', respectively.
11857 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11858 background extension.
11860 2011-05-10 Jim Meyering <meyering@redhat.com>
11862 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11864 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11866 * image.c (Finit_image_library): Return t for built-in image types,
11867 like pbm and xbm. (Bug#8640)
11869 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11871 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11873 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11875 * w32console.c (Fset_screen_color): Doc fix.
11876 (Fget_screen_color): New function.
11877 (syms_of_ntterm): Defsubr it.
11879 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11880 unlink the temporary file if Fcall_process didn't create it in the
11882 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11883 child process will be redirected to a file specified with `:file'.
11884 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11885 cue to call_process_cleanup not to close that handle.
11887 2011-05-07 Ben Key <bkey76@gmail.com>
11889 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11890 one of two shell specific rules, either bootstrap-temacs-CMD or
11891 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11892 to the previous implementation of the bootstrap-temacs rule.
11893 The bootstrap-temacs-CMD rule is similar to the previous
11894 implementation of the bootstrap-temacs rule except that it
11895 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11898 These changes, along with some changes to nt/configure.bat,
11899 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11900 earlier fix to add support for --cflags and --ldflags options
11901 that include quotes so that it works whether make uses cmd or
11904 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11906 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11907 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11909 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11910 a string. Handle both cases.
11911 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11912 (Fdbus_register_method): Use Qinvalid_function.
11914 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11916 * makefile.w32-in: Update dependencies.
11917 (LISP_H): Add inttypes.h and stdin.h.
11918 (PROCESS_H): Add unistd.h.
11920 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11922 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11923 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11925 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11927 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11929 * term.c (vfatal): Remove stray call to va_end.
11930 It's not needed and the C Standard doesn't allow it here anyway.
11932 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11933 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11935 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11938 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11940 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11942 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11944 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11946 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11948 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11949 * charset.c (Fdefine_charset_internal): Don't initialize
11950 charset.code_space[15]. The value was garbage, on hosts with
11951 32-bit int (Bug#8600).
11953 * lread.c (read_integer): Be more consistent with string-to-number.
11954 Use string_to_number to do the actual conversion; this avoids
11955 rounding errors and fixes some other screwups. Without this fix,
11956 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11957 (digit_to_number): Move earlier, for benefit of read_integer.
11958 Return -1 if the digit is out of range for the base, -2 if it is
11959 not a digit in any supported base. (Bug#8602)
11961 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11963 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11964 to match comment at start of function. This also removes a
11965 GCC warning about overflow in a 32+64-bit port.
11967 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11969 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11970 Reported by Stefan Monnier in
11971 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11972 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11973 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11975 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11976 (EMACS_UINTPTR): Likewise, with uintptr_t.
11978 * lisp.h: Prefer 64-bit EMACS_INT if available.
11979 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11980 on 32-bit hosts that have 64-bit int, so that they can access
11982 However, temporarily disable this change unless the temporary
11983 symbol WIDE_EMACS_INT is defined.
11985 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11987 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11988 This removes an assumption that EMACS_INT and long are the same
11989 width as pointers. The assumption is true for Emacs porting targets
11990 now, but we want to make other targets possible.
11991 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11992 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11993 In the rest of the code, change types of integers that hold casted
11994 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11995 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11996 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11997 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11998 No need to cast type when ORing.
11999 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12000 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12001 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12002 assume EMACS_INT is the same width as char *.
12003 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12004 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12005 Remove no-longer-needed casts.
12006 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12007 (xg_tool_bar_help_callback, xg_make_tool_item):
12008 Use EMACS_INTPTR to hold an integer
12009 that will be cast to void *; this can avoid a GCC warning
12010 if EMACS_INT is not the same width as void *.
12011 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12012 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12013 (current_message_1, set_message_1):
12014 Use a local to convert to proper width without a cast.
12015 * xmenu.c (dialog_selection_callback): Likewise.
12017 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12018 Also, don't assume VALBITS / RAND_BITS is less than 5,
12019 and don't rely on undefined behavior when shifting a 1 left into
12021 * lisp.h (get_random): Change signature to match.
12023 * lread.c (hash_string): Use size_t, not int, for hash computation.
12024 Normally we prefer signed values; but hashing is special, because
12025 it's better to use unsigned division on hash table sizes so that
12026 the remainder is nonnegative. Also, size_t is the natural width
12027 for hashing into memory. The previous code used 'int', which doesn't
12028 retain enough info to hash well into very large tables.
12029 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12031 * dbusbind.c: Don't possibly lose pointer info when converting.
12032 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12033 Use XPNTR rather than XHASH, so that the high-order bits of
12034 the pointer aren't lost when converting through void *.
12036 * eval.c (Fautoload): Don't double-shift a pointer.
12038 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12040 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12042 * gnutls.c (DEF_GNUTLS_FN):
12043 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12045 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12047 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12050 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12052 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12053 New version that can reserve upto 2GB of heap space.
12055 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12057 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12059 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12061 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12062 `gnutls_certificate_set_x509_key_file'.
12064 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12066 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12067 Update dependencies.
12069 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12071 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12072 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12073 Remove unused parameter `fildes'.
12074 * process.c (read_process_output, send_process): Don't pass it.
12076 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12078 Fix previous change: the library cache is defined in w32.c.
12079 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12080 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12082 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12084 Implement dynamic loading of GnuTLS on Windows.
12086 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12087 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12088 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12091 * gnutls.c (Qgnutls_dll): Define.
12092 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12093 (gnutls_*): Declare function pointers.
12094 (init_gnutls_functions): New function to initialize function pointers.
12095 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12096 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12097 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12098 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12099 (emacs_gnutls_write, emacs_gnutls_read)
12100 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12101 (Fgnutls_available_p): New function.
12102 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12103 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12104 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12106 * image.c: Include w32.h.
12107 (Vimage_type_cache): Delete.
12108 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12109 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12110 (w32_delayed_load): Move to w32.c.
12112 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12114 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12115 (w32_delayed_load): Move from image.c. When loading a library, record
12116 its filename in the :loaded-from property of the library id.
12117 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12118 Initialize and staticpro them.
12119 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12121 * process.c: Include lisp.h before w32.h, not after.
12122 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12123 instead of gnutls_record_check_pending.
12125 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12127 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12129 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12130 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12133 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12135 * xterm.c (x_set_frame_alpha): Do not set property on anything
12136 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12138 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12140 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12142 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12144 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12145 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12151 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12152 (Qgnutls_bootprop_callbacks_verify): Make static.
12154 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12156 * callproc.c: Indentation fixup.
12158 * sysdep.c (wait_for_termination_1): Make static.
12159 (wait_for_termination, interruptible_wait_for_termination):
12160 Move after wait_for_termination_1.
12162 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12164 * sysdep.c (interruptible_wait_for_termination): New function
12165 which is like wait_for_termination, but allows keyboard
12168 * callproc.c (Fcall_process): Add (:file "file") as an option for
12170 (Fcall_process_region): Ditto.
12172 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12174 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12175 rather than `XVECTOR (FOO)->size'.
12177 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12178 inttypes.h, as a gnulib replacement is used if it not available in
12181 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12183 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12184 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12185 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12187 * coding.c (coding_alloc_by_realloc): Error out if destination
12188 will grow beyond MOST_POSITIVE_FIXNUM.
12189 (decode_coding_emacs_mule): Abort if there isn't enough place in
12190 charbuf for the composition carryover bytes. Reserve an extra
12191 space for up to 2 characters produced in a loop.
12192 (decode_coding_iso_2022): Abort if there isn't enough place in
12193 charbuf for the composition carryover bytes.
12195 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12197 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12198 aborting when %lld or %lll format is passed.
12199 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12200 %llo or %llx format is passed. (Bug#8545)
12202 * window.c (window_scroll_line_based): Use a marker instead of
12203 simple variables to record original value of point. (Bug#7952)
12205 * doprnt.c (doprnt): Fix the case where a multibyte sequence

12210 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12211 (SIZE_MAX): Move defn after all includes, as they might #define it.
12213 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12215 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12217 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12219 * keyboard.c (Qdelayed_warnings_hook): Define.
12220 (command_loop_1): Run `delayed-warnings-hook'
12221 if Vdelayed_warnings_list is non-nil.
12222 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12223 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12225 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12227 * doprnt.c (doprnt): Don't return value smaller than the buffer
12228 size if the message was truncated. (Bug#8545).
12230 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12232 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12233 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12235 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12237 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12239 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12241 * makefile.w32-in: Update dependencies.
12243 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12245 Improve `doprnt' and its usage. (Bug#8545)
12246 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12247 `format_end'. Remove support for %l as a conversion specifier.
12248 Don't use xrealloc. Improve diagnostics when the %l size modifier
12249 is used. Update the commentary.
12251 * eval.c (verror): Simplify calculation of size_t.
12253 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12256 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12258 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12261 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12263 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12264 This makes this file independent of the recent pseudovector change.
12266 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12268 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12270 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12271 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12272 Remove unused local.
12273 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12275 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12276 GCC 4.6.0 optimizes based on type-based alias analysis.
12277 For example, if b is of type struct buffer * and v of type struct
12278 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12279 != &v->size, and therefore "v->size = 1; b->size = 2; return
12280 v->size;" must therefore return 1. This assumption is incorrect
12281 for Emacs, since it type-puns struct Lisp_Vector * with many other
12282 types. To fix this problem, this patch adds a new type struct
12283 vectorlike_header that documents the constraints on layout of vectors
12284 and pseudovectors, and helps optimizing compilers not get fooled
12285 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12286 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12287 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12289 (XSETPVECTYPE): Rewrite in terms of new macro.
12290 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12291 This is a bit clearer, and further avoids the possibility of
12292 undesirable aliasing.
12293 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12294 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12295 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12296 since Lisp_Subr is a special case (no "next" field).
12297 (ASIZE): Now uses header.size rather than size.
12298 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12299 to avoid the hassle of writing XVECTOR (foo)->header.size.
12300 (struct vectorlike_header): New type.
12301 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12302 object, to help avoid aliasing.
12303 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12304 (SUBRP): Likewise, since Lisp_Subr is a special case.
12305 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12306 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12307 (struct Lisp_Hash_Table): Combine first two members into a single
12308 struct vectorlike_header member. All uses of "size" and "next" members
12309 changed to be "header.size" and "header.next".
12310 * buffer.h (struct buffer): Likewise.
12311 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12312 * frame.h (struct frame): Likewise.
12313 * process.h (struct Lisp_Process): Likewise.
12314 * termhooks.h (struct terminal): Likewise.
12315 * window.c (struct save_window_data, struct saved_window): Likewise.
12316 * window.h (struct window): Likewise.
12317 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12318 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12319 * buffer.c (init_buffer_once): Likewise.
12320 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12322 * process.c (Fformat_network_address): Use local var for size,
12325 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12327 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12328 * data.c (atof): Remove decl; no longer used or needed.
12329 (digit_to_number): Move to lread.c.
12330 (Fstring_to_number): Use new string_to_number function, to be
12331 consistent with how the Lisp reader treats infinities and NaNs.
12332 Do not assume that floating-point numbers represent EMACS_INT
12333 without losing information; this is not true on most 64-bit hosts.
12334 Avoid double-rounding errors, by insisting on integers when
12335 parsing non-base-10 numbers, as the documentation specifies.
12336 * lisp.h (string_to_number): New decl, replacing ...
12337 (isfloat_string): Remove.
12338 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12339 (read1): Do not accept +. and -. as integers; this
12340 appears to have been a coding error. Similarly, do not accept
12341 strings like +-1e0 as floating point numbers. Do not report
12342 overflow for integer overflows unless the base is not 10 which
12343 means we have no simple and reliable way to continue.
12344 Break out the floating-point parsing into a new
12345 function string_to_number, so that Fstring_to_number parses
12346 floating point numbers consistently with the Lisp reader.
12347 (digit_to_number): Move here from data.c. Make it static inline.
12348 (E_CHAR, EXP_INT): Remove, replacing with ...
12349 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12350 (string_to_number): New function, replacing isfloat_string.
12351 This function checks for valid syntax and produces the resulting
12352 Lisp float number too. Rework it so that string-to-number
12353 no longer mishandles examples like "1.0e+". Use strtoumax,
12354 so that overflow for non-base-10 numbers is reported only when
12355 there's no portable and simple way to convert to floating point.
12357 * textprop.c (set_text_properties_1): Rewrite for clarity,
12358 and to avoid GCC warning about integer overflow.
12360 * intervals.h (struct interval): Use EMACS_INT for members
12361 where EMACS_UINT might cause problems. See
12362 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12363 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12364 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12366 (offset_intervals): Tell GCC not to worry about length overflow
12367 when negating a negative length.
12369 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12370 (overrun_check_free): Likewise.
12372 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12373 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12376 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12377 (gnutls_make_error): Rename local to avoid shadowing.
12378 (gnutls_emacs_global_deinit): ifdef out; not used.
12379 (Fgnutls_boot): Use const for pointer to readonly storage.
12380 Comment out unused local. Fix pointer signedness problems.
12382 * lread.c (openp): Don't stuff size_t into an 'int'.
12383 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12384 about possible signed overflow.
12386 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12387 (GDK_KEY_g): Don't define if already defined.
12388 (xg_prepare_tooltip): Avoid pointer signedness problem.
12389 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12391 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12392 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12394 * xfns.c (Fx_window_property): Simplify a bit,
12395 to make a bit faster and to avoid GCC 4.6.0 warning.
12396 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12398 * fns.c (internal_equal): Don't assume size_t fits in int.
12400 * alloc.c (compact_small_strings): Tighten assertion a little.
12402 Replace pEd with more-general pI, and fix some printf arg casts.
12403 * lisp.h (pI): New macro, generalizing old pEd macro to other
12404 conversion specifiers. For example, use "...%"pI"d..." rather
12405 than "...%"pEd"...".
12406 (pEd): Remove. All uses replaced with similar uses of pI.
12407 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12408 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12409 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12410 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12411 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12412 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12413 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12415 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12416 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12417 * print.c (safe_debug_print, print_object): Likewise.
12418 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12420 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12421 avoiding the 0 flag, which is not portable.
12422 * process.c (Fmake_network_process): Use pI to avoid cast.
12423 * region-cache.c (pp_cache): Likewise.
12424 * xdisp.c (decode_mode_spec): Likewise.
12425 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12426 behavior on 64-bit hosts with printf arg.
12427 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12428 (x_stop_queuing_selection_requests): Likewise.
12429 (x_get_window_property): Don't truncate byte count to an 'int'
12432 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12433 here, since it parses constructs like leading '-' and spaces,
12434 which are not wanted; and it overflows with large numbers.
12435 Instead, simply match F[0-9]+, which is what is wanted anyway.
12437 * alloc.c: Remove unportable assumptions about struct layout.
12438 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12439 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12440 (allocate_vectorlike, make_pure_vector): Use the new macros,
12441 plus offsetof, to remove unportable assumptions about struct layout.
12442 These assumptions hold on all porting targets that I know of, but
12443 they are not guaranteed, they're easy to remove, and removing them
12444 makes further changes easier.
12446 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12447 This doesn't fix a bug but makes the code clearer.
12448 (string_overrun_cookie): Now const. Use initializers that
12449 don't formally overflow signed char, to avoid warnings.
12450 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12451 can cause Emacs to crash when string overrun checking is enabled.
12452 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12453 multiple of sizeof (EMACS_INT); it need not be, if
12454 alignof(EMACS_INT) < sizeof (EMACS_INT).
12455 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12457 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12464 supposed to be handshaking. (Bug#8556)
12465 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12467 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12469 * lisp.h (Qdebug): List symbol.
12470 * eval.c (Qdebug): Restore global linkage.

12472 (handle_user_signal): Break into debugger when debug-on-event
12473 matches the current signal symbol.
12475 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12477 * alloc.c (check_sblock, check_string_bytes)
12478 (check_string_free_list): Convert to standard C.
12480 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12482 * w32.c (emacs_gnutls_push): Fix typo.
12484 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12486 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12487 "cast to pointer from integer of different size".
12489 Improve doprnt and its use in verror. (Bug#8545)
12490 * doprnt.c (doprnt): Document the set of format control sequences
12491 supported by the function. Use SAFE_ALLOCA instead of always
12494 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12495 is one byte too soon. Don't use xrealloc; instead xfree and
12498 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12500 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12503 * gnutls.c: Renamed global_initialized to
12504 gnutls_global_initialized. Added internals for the
12505 :verify-hostname-error, :verify-error, and :verify-flags
12506 parameters of `gnutls-boot' and documented those parameters in the
12507 docstring. Start callback support.
12508 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12509 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12510 on error. Return error code.
12511 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12512 (emacs_gnutls_read): Likewise.
12513 (Fgnutls_boot): Return handshake error code.

12577 <char-direction-table>: Deleted.
12579 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12581 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12582 * doprnt.c: Include limits.h.
12583 (SIZE_MAX): New macro.
12584 (doprnt): Return a size_t value. 2nd arg is now size_t.
12585 Many local variables are now size_t instead of int or unsigned.
12586 Improve overflow protection. Support `l' modifier for integer
12587 conversions. Support %l conversion. Don't assume an EMACS_INT
12588 argument for integer conversions and for %c.
12590 * lisp.h (doprnt): Restore prototype.
12592 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12593 $(SRC)/character.h.
12595 * Makefile.in (base_obj): Add back doprnt.o.
12597 * deps.mk (doprnt.o): Add back prerequisites.
12598 (callint.o): Depend on character.h.
12600 * eval.c (internal_lisp_condition_case): Include the handler
12601 representation in the error message.
12602 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12603 when breaking from the loop.
12605 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12607 * callint.c (Fcall_interactively): When displaying error message
12608 about invalid control letter, pass the character's codepoint, not
12609 a pointer to its multibyte form. Improve display of the character
12610 in octal and display also its hex code.
12612 * character.c (char_string): Use %x to display the (unsigned)
12613 codepoint of an invalid character, to avoid displaying a bogus
12616 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12617 `error', not SYMBOL_NAME itself.
12619 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12620 character arguments to `error'.
12622 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12623 to `error' in error message about FINAL_CHAR argument. Make sure
12624 FINAL_CHAR is a character, and use %c when it is passed as
12625 argument to `error'.
12627 2011-04-23 Eli Zaretskii <eliz@gnu.org>

12815 ns_descriptor_to_entity that were caused by using free to
12816 deallocate memory blocks that were allocated by xmalloc (via
12817 xstrdup). This caused Emacs to crash when compiled with

12837 (emacs_read, emacs_write): Use it.
12838 * process.c (send_process): Adjust to the new signatures of
12839 emacs_write and emacs_gnutls_write. Do not attempt to store

13171 * buffer.c (buffer_count): Remove unused var.
13173 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

13175 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13176 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13177 exported only to the debugger.
13179 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
13180 * atimer.h (run_all_atimers): Remove; not exported.
13182 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13183 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13184 was inaccessible from Lisp.
13185 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13186 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13188 alloc.c: Import and export fewer symbols, and remove unused items.
13189 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13191 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13192 it's not optimized away by whole-program optimization.

13194 (catchlist, handlerlist, mark_backtrace):
13195 Declare only if BYTE_MARK_STACK.

13204 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13205 (mark_backtrace): Define only if BYTE_MARK_STACK.
13206 * xdisp.c (message_enable_multibyte): Now static.
13208 Declare Lisp_Object Q* variables to be 'static' if not exported.
13209 This makes it easier for human readers (and static analyzers)
13210 to see whether these variables are used from other modules.
13211 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13212 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

13221 Remove decls of unexported vars.
13222 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13224 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13226 Make Emacs functions such as Fatom 'static' by default.
13227 This makes it easier for human readers (and static analyzers)
13228 to see whether these functions can be called from other modules.
13229 DEFUN now defines a static function. To make the function external
13230 so that it can be used in other C modules, use the new macro DEFUE.
13231 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13232 (Finit_image_library):
13233 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

13235 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13236 Remove decls, since these functions are now static.
13237 (Funintern, Fget_internal_run_time): New decls, since these functions
13238 were already external.
13240 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

13248 Mark functions with DEFUE instead of DEFUN,
13249 if they are used in other modules.
13250 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13251 decls for now-static functions.
13252 * buffer.h (Fdelete_overlay): Remove decl.

13288 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13290 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13291 when at ZV. (Bug#8487)
13293 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13295 * charset.c (Fclear_charset_maps): Use xfree instead of free.

13301 * xsettings.c (read_and_apply_settings): Likewise.
13303 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13304 (overrun_check_free): Protoize.
13306 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13308 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13309 since callers should never pass a negative size.
13310 Change the signature to match that of plain 'read' and 'write'; see
13311 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13312 * lisp.h: Update prototypes of emacs_write and emacs_read.
13314 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13316 * xdisp.c (redisplay_window): Don't try to determine the character
13317 position of the scroll margin if the window start point w->startp
13318 is outside the buffer's accessible region. (Bug#8468)
13320 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13322 Fix write-region and its subroutines for buffers > 2GB.
13323 * fileio.c (a_write, e_write): Modify declaration of arguments and
13324 local variables to support buffers larger than 2GB.
13325 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13327 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13328 argument, local variables, and return value.
13330 * lisp.h: Update prototypes of emacs_write and emacs_read.
13332 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13334 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13336 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13338 Fix more problems found by GCC 4.6.0's static checks.
13340 * xdisp.c (vmessage): Use a better test for character truncation.
13342 * charset.c (load_charset_map): <, not <=, for optimization,
13343 and to avoid potential problems with integer overflow.
13344 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13345 * casetab.c (set_identity, shuffle): Likewise.
13346 * editfns.c (Fformat): Likewise.
13347 * syntax.c (skip_chars): Likewise.
13349 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13350 This also lets GCC 4.6.0 generate slightly better loop code.
13352 * callint.c (Fcall_interactively): <, not <=, for optimization.
13353 (Fcall_interactively): Count the number of arguments produced,
13354 not the number of arguments given. This is simpler and lets GCC
13355 4.6.0 generate slightly better code.
13357 * ftfont.c: Distingish more carefully between FcChar8 and char.
13358 The previous code passed unsigned char * to a functions like
13359 strlen and xstrcasecmp that expect char *, which does not
13360 conform to the C standard.
13361 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13362 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13363 char * when the C standard requires it.
13365 * keyboard.c (read_char): Remove unused var.
13367 * eval.c: Port to Windows vsnprintf (Bug#8435).
13368 Include <limits.h>.
13369 (SIZE_MAX): Define if the headers do not.
13370 (verror): Do not give up if vsnprintf returns a negative count.
13371 Instead, grow the buffer. This ports to Windows vsnprintf, which
13372 does not conform to C99. Problem reported by Eli Zaretskii.
13373 Also, simplify the allocation scheme, by avoiding the need for
13374 calling realloc, and removing the ALLOCATED variable.
13376 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13378 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13379 But keep the doprint source code for now, as we might revamp it
13380 and use it again (Bug#8435).
13381 * lisp.h (doprnt): Remove.
13382 * Makefile.in (base_obj): Remove doprnt.o.
13383 * deps.mk (doprnt.o): Remove.
13385 error: Print 32- and 64-bit integers portably (Bug#8435).
13386 Without this change, on typical 64-bit hosts error ("...%d...", N)
13387 was used to print both 32- and 64-bit integers N, which relied on
13388 undefined behavior.
13389 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13390 * lisp.h (error, verror): Mark as printf-like functions.
13391 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13392 Report overflow in size calculations when allocating printf buffer.
13393 Do not truncate output string at its first null byte.
13394 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13395 Truncate the output at a character boundary, since vsnprintf does not
13397 * charset.c (check_iso_charset_parameter): Convert internal
13398 character to string before calling 'error', since %c now has the
13400 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13401 overflow when computing char to be passed to 'error'. Do not
13402 pass Lisp_Object to 'error'; pass the integer instead.
13403 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13404 formatted with plain %d.
13406 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13408 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13410 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13412 * xterm.c (x_catch_errors): Remove duplicate declaration.
13414 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13416 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13418 2011-04-10 Jim Meyering <meyering@redhat.com>
13420 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13421 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13422 return ssize_t not "int", and use size_t as the buffer length.
13423 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13424 * gnutls.h: Update declarations.
13425 * process.c (read_process_output): Use ssize_t, to match.
13426 (send_process): Likewise.
13428 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13430 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13432 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13434 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13435 Use unsigned char, to match FcChar8 type definition.
13437 * xterm.c (handle_one_xevent):
13438 * xmenu.c (create_and_show_popup_menu):
13439 * xselect.c (x_decline_selection_request)
13440 (x_reply_selection_request): Avoid type-punned deref of X events.
13442 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13444 Fix some uses of `int' instead of EMACS_INT.
13445 * search.c (string_match_1, fast_string_match)
13446 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13447 (scan_buffer, find_next_newline_no_quit)
13448 (find_before_next_newline, search_command, Freplace_match)
13449 (Fmatch_data): Make some `int' variables be EMACS_INT.
13451 * xdisp.c (display_count_lines): 3rd argument and return value now
13452 EMACS_INT. All callers changed.
13453 (pint2hrstr): Last argument is now EMACS_INT.
13455 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13456 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13457 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

13468 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13469 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13471 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13472 (encode_invocation_designation): Last argument P_NCHARS is now
13474 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13475 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13477 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13480 * ccl.c (Fccl_execute_on_string): Declare some variables
13483 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13485 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13487 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13489 * process.c (Fformat_network_address): Doc fix.
13491 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13493 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13495 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13497 * keyboard.c (read_char): Call Lisp function help-form-show,
13498 instead of using internal_with_output_to_temp_buffer.
13499 (Qhelp_form_show): New var.
13500 (syms_of_keyboard): Use DEFSYM macro.
13502 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13509 (list_processes_1): Delete.
13511 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13513 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13515 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13517 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13519 Fix more problems found by GCC 4.6.0's static checks.
13521 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

13534 printf-like functions.
13535 (tiff_load): Add casts to remove these marks before passing them
13536 to system-supplied API.
13538 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13540 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13541 This avoids several warnings with gcc -Wstrict-overflow.
13542 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13543 directly, rather than having caller test rule sign. This avoids
13544 some unnecessary tests.
13545 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13546 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13547 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13549 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13550 (xfont_open): Avoid unnecessary tests.
13552 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13554 * composite.h, composite.c (composition_gstring_put_cache):
13555 Use EMACS_INT, not int, for length.
13557 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13558 breaking out part of COMPOSITION_DECODE_RULE.
13559 (COMPOSITION_DECODE_RULE): Use it.
13560 * composite.c (get_composition_id): Remove unused local vars,
13561 by using the new macro.
13563 * textprop.c (set_text_properties_1): Change while to do-while,
13564 since the condition is always true at first.
13566 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13567 (interval_deletion_adjustment): Return unsigned value.
13570 * process.c (list_processes_1, create_pty, read_process_output):
13571 (exec_sentinel): Remove vars that were set but not used.
13572 (create_pty): Remove unnecessary "volatile"s.
13573 (Fnetwork_interface_info): Avoid possibility of int overflow.

13584 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13586 * print.c (print_error_message): Avoid int overflow.
13588 * font.c (font_list_entities): Redo for clarity,
13589 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13591 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13592 (font_score): Avoid potential overflow in diff calculation.

13595 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13597 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13599 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13600 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13601 can always succeed if overflow has undefined behavior.
13603 * search.c (boyer_moore, wordify): Remove vars set but not used.
13604 (wordify): Omit three unnecessary tests.
13606 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

13611 * dired.c (file_name_completion): Remove var that is set but not used.
13613 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13615 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13616 (Finsert_file_contents): Remove unnecessary code checking fd.
13618 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13619 Check for integer overflow on size calculations.
13621 * buffer.c (Fprevious_overlay_change): Remove var that is set
13624 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13625 Remove vars that are set but not used.
13626 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13627 (timer_check_2): Mark vars as initialized.
13629 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13631 * image.c (lookup_image): Remove var that is set but not used.
13632 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13634 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13635 that are set but not used.
13637 * xfns.c (make_invisible_cursor): Don't return garbage
13638 if XCreateBitmapFromData fails (Bug#8410).
13640 * xselect.c (x_get_local_selection, x_handle_property_notify):
13641 Remove vars that are set but not used.
13643 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13644 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13646 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13647 Remove var that is set but not used.
13648 (scroll_bar_windows_size): Now size_t, not int.
13649 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13650 Check for overflow.
13652 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13653 (map_tty_color) [!defined MSDOS]: Likewise.
13655 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13657 * coding.c: Remove vars that are set but not used.
13658 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13659 All callers changed.
13660 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13661 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13662 (decode_coding_charset): Remove vars that are set but not used.
13664 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13665 that is set but not used.
13667 * print.c (print_object): Remove var that is set but not used.
13669 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13670 The gnulib version avoids calling malloc in the usual case,
13671 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13672 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13673 * filelock.c (current_lock_owner): Likewise.
13674 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13675 * sysdep.c: Include allocator.h, careadlinkat.h.
13676 (emacs_no_realloc_allocator): New static constant.
13677 (emacs_readlink): New function.
13678 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13679 ../lib/careadlinkat.h.
13681 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13683 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13684 first non-nil return value).
13686 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13688 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13689 if not defined (Bug#8403).
13691 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13693 * xdisp.c (display_count_lines): Remove parameter `start',
13694 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13695 (get_char_face_and_encoding): Remove parameter `multibyte_p',

13698 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13699 and thereabouts. All callers changed.
13700 (get_per_char_metric): Remove parameter `f', unused since
13701 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13703 2011-04-02 Jim Meyering <meyering@redhat.com>
13705 do not dereference NULL upon failed strdup
13706 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13707 (ns_get_family): Likewise.
13709 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13711 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13713 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13715 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13718 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13720 Add lexical binding.
13722 * window.c (Ftemp_output_buffer_show): New fun.
13723 (Fsave_window_excursion):
13724 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13726 * lread.c (lisp_file_lexically_bound_p): New function.
13727 (Fload): Bind Qlexical_binding.
13728 (readevalloop): Remove `evalfun' arg.
13729 Bind Qinternal_interpreter_environment.
13730 (Feval_buffer): Bind Qlexical_binding.
13731 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13733 (syms_of_lread): Declare `lexical-binding'.
13735 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13737 * keyboard.c (eval_dyn): New fun.
13738 (menu_item_eval_property): Use it.
13740 * image.c (parse_image_spec): Use Ffunctionp.
13742 * fns.c (concat, mapcar1): Accept byte-code-functions.
13744 * eval.c (Fsetq): Handle lexical vars.
13745 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13746 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13747 (FletX, Flet): Obey lexical binding.
13748 (Fcommandp): Handle closures.
13749 (Feval): New `lexical' arg.
13750 (eval_sub): New function extracted from Feval. Use it almost
13751 everywhere where Feval was used. Look up vars in lexical env.
13753 (Ffunctionp): Move from subr.el.
13754 (Ffuncall): Handle closures.
13755 (apply_lambda): Remove `eval_flags'.
13756 (funcall_lambda): Handle closures and new byte-code-functions.
13757 (Fspecial_variable_p): New function.
13758 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13759 but without exporting it to Lisp.
13761 * doc.c (Fdocumentation, store_function_docstring):
13762 * data.c (Finteractive_form): Handle closures.
13764 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13767 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13769 (exec_byte_code): New function extracted from Fbyte_code to handle new
13770 calling convention for byte-code-functions. Add new byte-codes.
13772 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13774 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13776 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13778 * xdisp.c (redisplay_internal): Fix prototype.
13780 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13782 * xdisp.c (SCROLL_LIMIT): New macro.
13783 (try_scrolling): Use it when setting scroll_limit.
13784 Limit scrolling to 100 screen lines.
13785 (redisplay_window): Even when falling back on "recentering",
13786 position point in the window according to scroll-conservatively,
13787 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13789 (try_scrolling): When point is above the window, allow searching
13790 as far as scroll_max, or one screenful, to compute vertical
13791 distance from PT to the scroll margin position. This prevents
13792 try_scrolling from unnecessarily failing when
13793 scroll-conservatively is set to a value slightly larger than the
13794 window height. Clean up the case of PT below the margin at bottom
13795 of window: scroll_max can no longer be INT_MAX. When aggressive
13796 scrolling is in use, don't let point enter the opposite scroll
13797 margin as result of the scroll.
13798 (syms_of_xdisp) <scroll-conservatively>: Document the
13799 threshold of 100 lines for never-recentering scrolling.
13801 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13803 * dispextern.h (move_it_by_lines):

13806 (message_log_check_duplicate): Remove parameters `prev_bol' and
13807 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13808 (redisplay_internal): Remove parameter `preserve_echo_area',
13809 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13811 * indent.c (Fvertical_motion):
13812 * window.c (window_scroll_pixel_based, Frecenter):
13813 Don't pass `need_y_p' to `move_it_by_lines'.
13815 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13817 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13818 steal a few bits to be more compact.
13819 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13820 Remove unneeded casts.
13822 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13824 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13826 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13827 binding" message (bug#7967).
13829 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13831 Fix more problems found by GCC 4.6.0's static checks.
13833 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13834 Remove unused local var.
13836 * editfns.c (Fmessage_box): Remove unused local var.
13838 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13839 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13840 Omit unused local vars.
13841 * window.c (shrink_windows): Omit unused local var.
13842 * menu.c (digest_single_submenu): Omit unused local var.
13843 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13844 Omit unused local var.
13846 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13847 Don't assume string length fits in int.
13848 (keyremap_step, read_key_sequence): Use size_t for sizes.
13849 (read_key_sequence): Don't check last_real_key_start redundantly.
13851 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13852 instead of alloca (Bug#8344).
13854 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13855 (Fbacktrace_frame): Don't assume nframes fits in int.
13857 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13859 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13862 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13864 * cm.c (calccost): Turn while-do into do-while, for clarity.
13866 * keyboard.c (syms_of_keyboard): Use the same style as later
13867 in this function when indexing through an array. This also
13868 works around GCC bug 48267.
13870 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13872 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13874 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13875 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13877 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13878 This avoids undefined behavior on integer overflow, and is a bit
13879 more convenient anyway since it is compared to a size_t variable.
13881 Variadic C functions now count arguments with size_t, not int.
13882 This avoids an unnecessary limitation on 64-bit machines, which
13883 caused (substring ...) to crash on large vectors (Bug#8344).
13884 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13885 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13893 * fns.c (concat): Likewise.
13894 * frame.c (x_set_frame_parameters): Likewise.
13895 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13896 0 if not found, not -1. All callers changed.
13898 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13899 (stack_copy_size): Now size_t, not int.
13900 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13902 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13904 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13905 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13906 All callers changed.
13908 * lisp.h (multibyte_char_to_unibyte):
13909 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13910 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13918 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13920 * keyboard.c (safe_run_hook_funcall): New function.
13921 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13922 don't set the hook to nil, but remove the offending function instead.
13923 (Qcommand_hook_internal): Remove, unused.
13924 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13925 Vcommand_hook_internal.
13927 * eval.c (enum run_hooks_condition): Remove.
13928 (funcall_nil, funcall_not): New functions.
13929 (run_hook_with_args): Call each function through a `funcall' argument.

13943 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13944 All callers changed.
13946 * w32.c (_wsa_errlist): Use braces for struct initializers.
13948 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13949 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13950 All callers changed.

14106 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14108 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14109 unconditionally since it does the check itself.
14111 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14113 Fix more problems found by GCC 4.5.2's static checks.
14115 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14116 the first time through the loop, since we know p0 < p1 then.
14117 This also avoids a gcc -Wstrict-overflow warning.
14119 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14120 leading to a memory leak, possible in functions like
14121 load_charset_map_from_file that can allocate an unbounded number
14122 of objects (Bug#8318).
14124 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14125 that could (at least in theory) be that large.
14127 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14128 This is less likely to overflow, and avoids undefined behavior if
14129 overflow does occur. All callers changed. Use strtoul to scan
14130 for the unsigned long integer.
14131 (pint2hrstr): Simplify and tune code slightly.
14132 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14142 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14145 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14147 * process.c (Fmake_network_process): Use socklen_t, not int,
14148 where POSIX says socklen_t is required in portable programs.
14149 This fixes a porting bug on hosts like 64-bit HP-UX, where
14150 socklen_t is wider than int (Bug#8277).
14151 (Fmake_network_process, server_accept_connection):
14152 (wait_reading_process_output, read_process_output):
14155 * process.c: Rename or move locals to avoid shadowing.

14165 Make tparam.h and terminfo.c consistent.
14166 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14167 Include tparam.h instead, since it declares them.
14168 * cm.h (PC): Remove extern decl; tparam.h now does this.
14169 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14170 * terminfo.c: Include tparam.h, to check interfaces.
14171 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14172 (tparam): Adjust signature to match interface in tparam.h;
14173 this removes some undefined behavior. Check that outstring and len
14174 are zero, which they always are with Emacs.
14175 * tparam.h (PC, BC, UP): New extern decls.
14177 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14178 (xftfont_open): Rename locals to avoid shadowing.
14180 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14181 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

14192 * composite.c (composition_compute_stop_pos): Rename local to
14194 (composition_reseat_it): Remove unused locals.
14195 (find_automatic_composition, composition_adjust_point): Likewise.
14196 (composition_update_it): Mark var as initialized.
14197 (find_automatic_composition): Mark vars as initialized,
14198 with a FIXME (Bug#8290).

14202 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14203 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14204 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14205 to avoid shadowing.
14207 * textprop.c (property_change_between_p): Remove; unused.
14209 * intervals.c (interval_start_pos): Now static.
14211 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14217 Fix pointer signedness.
14218 (alsa_choose_format): Remove unused local var.
14219 (wav_play): Initialize a variable to 0, to prevent undefined
14220 behavior (Bug#8278).
14222 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14224 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14226 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14227 clobbering (Bug#8298).
14228 * sysdep.c (sys_subshell): Likewise.
14229 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14231 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14232 This should get cleaned up, so that child_setup has the
14233 same signature on all platforms.
14235 * callproc.c (call_process_cleanup): Now static.
14236 (relocate_fd): Rename locals to avoid shadowing.
14238 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14240 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14241 not to be necessary, and produces flickering.
14243 2011-03-20 Glenn Morris <rgm@gnu.org>
14245 * config.in: Remove file.
14247 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14249 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14250 are now in src/globals.h.
14251 (syms_of_minibuf): Remove spurious & from previous change.

14255 * minibuf.c (completing-read-function): New variable.
14256 (completing-read-default): Rename from completing-read.
14257 (completing-read): Call completing-read-function.

14277 (sigchld_handler): Now static.
14279 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14280 That way, the code declares only the vars that it needs.

14287 * process.c (allocate_pty): Don't declare stb unless it's needed.
14289 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
14290 (CONSTANTLIM): Remove; unused.
14291 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14292 Define only if needed.
14294 * unexelf.c (unexec): Name an expression,
14295 to avoid gcc -Wbad-function-cast warning.
14296 Use a different way to cause a compilation error if anyone uses
14297 n rather than nn, a way that does not involve shadowing.
14298 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14300 * deps.mk (unexalpha.o): Remove; unused.
14302 New file unexec.h, the (simple) interface for unexec (Bug#8267).

14368 (Fformat_time_string, Fencode_time, Finsert_char):
14369 (Ftranslate_region_internal, Fformat):
14370 Rename or remove local vars to avoid shadowing.

14376 * lisp.h (eassert): Check that the argument compiles, even if
14377 ENABLE_CHECKING is not defined.
14379 * data.c (Findirect_variable): Name an expression, to avoid
14380 gcc -Wbad-function-cast warning.

14422 (regex_compile, re_match_2_internal): Mark locals as initialized.
14423 (RETALLOC_IF): Define only if needed.
14424 (WORDCHAR_P): Likewise. This one is never needed, but is used
14425 only in a comment talking about a compiler bug, so put inside
14426 the #if 0 of that comment.
14427 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14428 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14431 * search.c (boyer_moore): Rename locals to avoid shadowing.

14456 gcpro1, gcpro2, etc.
14457 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14459 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14460 argument, for consistency with GCPRO2_VAR, etc: it is now the

14464 Rename locals to avoid shadowing.
14466 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14467 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14468 dired.c's scmp function, had undefined behavior.

14470 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14471 * buffer.h: ... to here, because these macros use current_buffer,
14472 and the new implementation with inline functions needs to have
14473 current_buffer in scope now, rather than later when the macros
14475 (downcase, upcase1): New static inline functions.
14476 (DOWNCASE, UPCASE1): Reimplement using these functions.
14477 This avoids undefined behavior in expressions like
14478 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14479 from race conditions in accessing the global variables
14480 case_temp1 and case_temp2.

14492 (file_name_as_directory): Use const pointers when appropriate.
14493 (Fexpand_file_name): Likewise. In particular, newdir might
14494 point at constant storage, so make it a const pointer.

14498 (Fset_file_times, Finsert_file_contents, auto_save_error):

14505 * marker.c (bytepos_to_charpos): Remove; unused.
14507 * lisp.h (verify_bytepos, count_markers): New decls,
14508 so that gcc does not warn that these functions aren't declared.

14511 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14512 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.

14518 * buffer.c (fix_overlays_before): Mark locals as initialized.
14519 (fix_start_end_in_overlays): Likewise. This function should be
14520 simplified by using pointers-to-pointers, but that's a different
14522 (switch_to_buffer_1): Now static.
14523 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14524 (report_overlay_modification): Rename locals to avoid shadowing.

14529 to suppress a gcc -Wclobbered warning that does not seem to be right.
14530 (MAXPATHLEN): Define only if needed.
14532 * process.c (serial_open, serial_configure): Move decls from here ...
14533 * systty.h: ... to here, so that they can be checked.
14535 * fns.c (get_random, seed_random): Move extern decls from here ...
14536 * lisp.h: ... to here, so that they can be checked.
14538 * sysdep.c (reset_io): Now static.
14539 (wait_for_termination_signal): Remove; unused.

14547 (describe_map_tree):
14548 Rename locals to avoid shadowing.
