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

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

132 Remove unnecessary casts involving pointers.
133 These casts are no longer needed now that we assume C89 or later,

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

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

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

229 * composite.c (COMPOSITE_INLINE):
230 * dispnew.c (DISPEXTERN_INLINE):
231 * sysdep.c (SYSTIME_INLINE):
232 Define to EXTERN_INLINE, so that the corresponding functions
233 are compiled into code.
234 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
235 (INLINE_HEADER_END): New macros.
236 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

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

515 2012-07-30 Glenn Morris <rgm@gnu.org>
517 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
518 does that unconditionally. Remove file, which is now empty.
520 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
523 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

644 w32_console_unicode_input.
645 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
646 (w32_kbd_patch_key, key_event): Use the codepage returned by

668 2012-07-27 Michael Albinus <michael.albinus@gmx.de>
670 * dbusbind.c (XD_DBUS_VALIDATE_BUS_ADDRESS): Canonicalize session
672 (xd_close_bus, Fdbus_init_bus): Handle reference counter properly.
674 2012-07-27 Eli Zaretskii <eliz@gnu.org>
676 * alloc.c (listn): Fix the order the arguments are consed onto the
679 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
680 enumeration constants, as PURE and HEAP are too general, and clash
681 with other headers and sources, such as gmalloc.c and the
682 MS-Windows system headers. All users changed.
684 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
686 Revert last save_excursion_save and save_excursion_restore changes.
687 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

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

731 * xfns.c (syms_of_xfns): Likewise.
733 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
735 Fast save_excursion_save and save_excursion_restore.
736 * lisp.h (struct Lisp_Excursion): New data type.
737 (PVEC_EXCURSION): New pseudovector type.

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

766 (DATA_SEG_BITS): Use it.
767 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
768 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
769 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
770 not be usable in #if. This simplifies things.
772 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
774 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
776 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

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

821 add argument, tune behavior, and adjust all callers.
823 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
825 Use typedef for EMACS_INT, EMACS_UINT.
826 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
827 than macros. This simplifies debugging in the usual case, since
828 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
829 and it allows expressions involving EMACS_INT casts.
830 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
832 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
834 * nsterm.m (ns_read_socket): Return early if there is a modal

844 Adjust buffer text indirection counters at the end of Fkill_buffer.
845 * buffer.c (Fkill_buffer): Adjust indirection counters when the
846 buffer is definitely dead. This should really fix an issue reported
847 by Christoph Scholtes again. (Bug#12007).
848 (init_buffer_once): Initialize indirection counters of
849 buffer_defaults and buffer_local_symbols (for sanity and safety).
851 2012-07-24 Eli Zaretskii <eliz@gnu.org>
853 * xdisp.c (init_iterator): Don't compute dimensions of truncation
854 and continuation glyphs on tooltip frames, leave them at zero.
855 Avoids continued lines in tooltips. (Bug#11832)
857 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
859 Simplify copy_overlay.
860 * buffer.c (copy_overlay): Simplify. Use build_marker.
861 * lisp.h (struct Lisp_Overlay): Restore comment with minor tweaks.
863 2012-07-23 Eli Zaretskii <eliz@gnu.org>

866 or invalid. (Bug#12025)
868 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
869 it signals an error when a tooltip frame is being created.
871 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
873 Cleanup miscellaneous objects allocation and initialization.
874 * alloc.c (allocate_misc): Change to static. Add argument to

877 * buffer.c (copy_overlays, Fmake_overlay): Use it.
878 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

882 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
884 Swap buffer text indirection counters in Fbuffer_swap_text.
885 * buffer.c (Fbuffer_swap_text): Swap indirections too.
886 This avoids crash reported by Christoph Scholtes at
887 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
889 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
891 * nsmenu.m (Popdown_data): New struct.
892 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
894 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
895 (initWithContentRect): Make imgView and contentView non-static
896 and autorelease them. Also autorelease img and matrix (Bug#12005).
897 (dealloc): Remove (Bug#12005).
899 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

910 (live_buffer, set_marker_internal): New function.
911 (Fset_marker, set_marker_restricted): Use set_marker_internal.
912 (set_marker_both, set_marker_restricted_both): Use live_buffer.
914 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
916 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
917 as it's limited by the amount of memory, not by INT_MAX.
919 2012-07-21 Eli Zaretskii <eliz@gnu.org>
921 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

1645 * s/aix4-2.h (unix): Remove; no longer needed.
1647 EMACS_TIME simplification (Bug#11875).
1648 This replaces macros (which typically do not work in GDB)

1650 The functional style also makes code easier to read and maintain.
1651 * systime.h: Include <sys/time.h> on all hosts, not just if
1652 WINDOWSNT, since 'struct timeval' is needed in general.

1668 (add_emacs_time, sub_emacs_time): New functions.
1669 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1692 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1693 Prefer snprintf to strncpy.
1694 * nsterm.m (ns_term_init):
1695 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1696 * nsterm.m (ns_term_init):
1697 Avoid the need for strncpy, by using build_string or
1698 make_unibyte_string directly. Use dtoastr, not snprintf.
1699 * process.c (Fmake_network_process): Diagnose service names that
1700 are too long, rather than silently truncating them or creating
1701 non-null-terminated names.
1702 (Fnetwork_interface_info): Likewise, for interface names.

1718 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1719 where argument type is known to be a Lisp_Cons.

1774 O_RDONLY already includes it).
1776 Stop ns builds setting the EMACSLOADPATH environment variable.
1777 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1778 Now it does not set EMACSLOADPATH, just returns the load-path string.

1780 * lread.c [HAVE_NS]: Include nsterm.h.
1781 (init_lread) [HAVE_NS]: Use ns_load_path.

1791 (ns_init_paths): Do not set EMACSPATH.

1842 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
1843 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
1844 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
1845 * nsterm.h (ns_etc_directory): Add it.
1846 * callproc.c [HAVE_NS]: Include nsterm.h.
1847 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1849 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1851 Move marker debugging code under MARKER_DEBUG.
1852 * marker.c (MARKER_DEBUG): Move marker debugging code under
1853 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1854 for bootstrap with --enable-checking (~3x slowdown reported
1855 by Juanma Barranquero <lekktu@gmail.com>).
1856 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1858 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1860 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1861 See <http://bugs.gnu.org/11825#29>.
1863 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1865 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1866 has no font, use the frame's font. (Bug#11813)
1867 (display_line): Add commentary about displaying truncation glyphs
1869 (produce_special_glyphs): Move here from term.c.
1871 * term.c (produce_special_glyphs): Move to xdisp.c.
1873 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1876 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1878 * xdisp.c (display_line): Avoid warning about implicit declaration
1881 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1883 * lisp.h: Remove empty conditional.
1885 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1887 * lread.c (load_path_check): Now static.
1889 Fix some minor --with-ns problems found by static checking.
1890 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1891 (x_set_font) [!HAVE_X_WINDOWS]:
1892 * image.c (xpm_load_image) [HAVE_NS]:
1893 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1894 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1895 Remove unused local.
1896 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1897 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1898 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1899 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1900 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1901 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1902 Fix pointer signedness problem.
1903 * xfaces.c (FRAME_X_FONT_TABLE):
1904 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1906 2012-07-07 Glenn Morris <rgm@gnu.org>
1908 * lread.c (load_path_check): New function, split from init_lread.
1909 (init_lread): Reorganize. Motivation:
1910 If EMACSLOADPATH is set, check/warn about that rather than the
1911 defaults, which we are not going to use. Hence we can remove
1912 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1913 Don't warn if site-lisp directories are missing.
1914 If not installed, start from a blank load-path, since
1915 PATH_LOADSEARCH refers to the eventual installation directories.
1917 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1919 Support truncation and continuation glyphs on GUI frames, when
1920 fringes are disabled. (Bug#11832)
1921 * xdisp.c (init_iterator): Get dimensions of truncation and
1922 continuation glyphs even if on GUI frames. Adjust
1923 it->last_visible_x on GUI frames when the left or right fringes,
1924 or both, are absent.
1925 (start_display, move_it_in_display_line_to): Handle the case of a
1926 GUI frame without a fringe to display continuation or truncation
1928 (insert_left_trunc_glyphs): Support GUI frames: make sure
1929 truncation glyphs overwrite enough glyphs from the current line to
1930 have sufficient space in pixels.
1931 (display_line): Support truncation and continuation glyphs on GUI
1932 frames. If some spare pixels are left on the line after inserting
1933 the truncation glyphs, fill that space with a stretch glyph of a
1934 suitably computed width.
1936 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1937 produce_glyphs, to support GUI sessions.
1939 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1941 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1943 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1945 Do not require float-time's arg to fit in time_t (Bug#11825).
1946 This works better on hosts where time_t is unsigned, and where
1947 float-time is applied to the (negative) difference between two times.
1948 * editfns.c (decode_time_components): Last arg is now double *,
1949 not int *, and means to store all the result as a double, without
1950 worrying about whether the seconds part fits in time_t.
1951 All callers changed.
1952 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1953 All callers changed.
1954 (Ffloat_time): Do not fail merely because the specified time falls
1955 outside of time_t range.
1957 2012-07-07 Glenn Morris <rgm@gnu.org>
1959 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1960 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

1963 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1965 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1966 Update dependencies.
1968 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1970 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1972 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1973 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1974 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1975 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1976 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1977 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1979 * xfont.c (compare_font_names): Redo to omit the need for casts.
1981 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1983 * xfns.c (Fx_change_window_property): Doc fix.
1984 * w32fns.c (Fx_change_window_property): Doc fix.
1986 * w32fns.c (Fx_window_property): Accept the same arguments as the
1987 X Windows version. Doc fix.
1988 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1990 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1991 Eli Zaretskii <eliz@gnu.org>
1993 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1994 Windows-specific code from nt/config.nt moved here.
1995 Obsolete settings removed.
1997 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1999 * process.c: Avoid unnecessary calls to gettime.
2000 (wait_reading_process_output): Don't get the time of day
2001 when gobbling data immediately and not waiting, as there's no need
2002 for it in that case. This removes a FIXME.
2004 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2006 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2007 is defined (Bug#11768).
2009 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2011 Fix marker debugging code.
2012 * marker.c (byte_char_debug_check): Do not perform the check
2013 if buffer is not multibyte.
2014 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2015 Call byte_char_debug_check with correct arguments.
2017 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2019 Compile marker debugging code only if ENABLE_CHECKING is defined.
2020 * marker.c (byte_char_debug_check, count_markers):
2021 Use only if ENABLE_CHECKING is defined.
2022 (byte_debug_flag): Remove.
2023 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2024 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2026 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2028 Avoid code repetition in marker-related functions.
2029 * marker.c (attach_marker): New function.
2030 (Fset_marker, set_marker_restricted, set_marker_both)
2031 (set_marker_restricted_both): Use it.
2032 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2033 Consistently rename charno to charpos.
2034 (marker_position): Add eassert.
2035 (marker_byte_position): Convert to eassert.
2037 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

2047 * lisp.h (build_marker): New prototype.
2048 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
2049 * composite.c (autocmp_chars): Likewise.
2050 * editfns.c (buildmark): Remove.
2051 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2052 (save_restriction_save): Use build_marker.
2053 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2054 * window.c (save_window_save): Likewise.
2056 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2058 Do not use Fdelete_overlay in delete_all_overlays
2059 to avoid redundant calls to unchain_overlay.
2060 * buffer.c (drop_overlay): New function.
2061 (delete_all_overlays, Fdelete_overlay): Use it.
2062 * minibuf.c (get_minibuffer): Fix comment.
2064 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2066 Port to OpenBSD 5.1 amd64.
2067 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2068 This is needed for OpenBSD, and should be harmless on all BSD systems.
2069 Also, include <sys/sysctl.h>, as it should be available on all
2070 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2071 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2072 use p_pid member, not kp_proc.pid.
2074 2012-07-06 Glenn Morris <rgm@gnu.org>
2076 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2078 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2080 More xmalloc and related cleanup.
2081 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2082 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2085 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2086 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2087 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2088 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2089 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2091 Omit needless casts involving void * pointers and allocation.
2092 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2093 as the former is more robust if P's type is changed.
2094 Prefer xzalloc to xmalloc + memset 0.
2095 Simplify malloc-or-realloc to realloc.
2096 Don't worry about xmalloc returning a null pointer.
2097 Prefer xstrdup to xmalloc + strcpy.
2098 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2100 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2101 alloca of a constant.
2103 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2105 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2106 hscroll is larger than the line width. Fixes long and futile
2107 looping inside extend_face_to_end_of_line (on a TTY) producing
2108 glyphs that are not needed and thrown away.
2110 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2112 * marker.c (set_marker_restricted_both): Simplify by using
2115 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2117 * editfns.c (region_limit): Simplify by using clip_to_bounds.
2119 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
2121 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is

2124 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2125 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2126 followed by gtk_box_set_homogeneous (Bug#11768).
2127 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2128 (update_theme_scrollbar_width, xg_create_scroll_bar):
2129 Use gtk_scrollbar_new (Bug#11768).
2130 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2131 (is_box_type): New function (Bug#11768).
2132 (xg_tool_item_stale_p): Call is_box_type.
2133 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2134 with default display (Bug#11768).
2136 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2138 * xdisp.c (window_hscroll_limited): New function.
2139 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2140 coordinates when window's hscroll is set to insanely large
2143 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2145 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2146 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2148 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2151 * lisp.h (xzalloc): New prototype. Omit needless casts.
2152 * alloc.c (xzalloc): New function. Omit needless casts.
2153 * charset.c: Omit needless casts. Convert all calls to
2154 xmalloc with following memset to xzalloc.

2204 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2206 * fileio.c (time_error_value): Check the right error number.
2207 Problem reported by Troels Nielsen in
2208 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2210 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2212 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2213 This should be fixed in a better way; see Eli Zaretskii in
2214 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2215 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2217 * fileio.c (time_error_value): Rename from special_mtime.
2218 The old name's problems were noted by Eli Zaretskii in
2219 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2221 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2222 This variable's comment says Emacs needs at least one GDB-visible
2223 symbol of type enum pvec_type, to work around GDB problems.
2224 The symbol's value doesn't matter.
2226 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2227 that causes compilation to fail on pre-C99 compilers.
2229 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2231 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2232 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2234 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2236 * buffer.c (init_buffer_once): Fix initialization of
2237 headers for buffer_defaults and buffer_local_symbols.
2238 Reported by Juanma Barranquero <lekktu@gmail.com>.
2240 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2242 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2243 * lisp.h (enum pvec_type): Use fewer bits.
2244 (PSEUDOVECTOR_SIZE_BITS): New constant.
2245 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2246 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2247 change in pvec_type.
2248 (PSEUDOVECTOR_TYPEP): New macro.
2249 (TYPED_PSEUDOVECTORP): Use it.
2250 * fns.c (internal_equal): Adapt code to extract pvectype.
2251 * emacs.c (gdb_pvec_type): Update type.
2252 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2253 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2254 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2255 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2256 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2257 abusing vector->header.next.nbytes.
2258 (live_vector_p): Use PVEC_TYPE.
2259 (mark_object): Adapt code to extract pvectype. Use switch.
2261 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2263 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2264 Tighten new eassert a bit.
2266 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2268 Fix compilation with --enable-gcc-warnings and -O1
2270 * doprnt.c (doprnt): Change type of tem to int, initialize
2271 to avoid compiler warning. Add eassert.
2272 * search.c (simple_search): Initialize match_byte to avoid
2273 compiler warning. Add eassert.
2275 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2277 Avoid weird behavior with large horizontal scrolls.
2278 Without this change, for example, large hscroll values would
2279 mess up Emacs's display on Fedora 15 x86, presumably due to
2280 overflows in int calculations in the display code.
2281 Also, if buffers had long lines, Emacs would freeze.
2282 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2283 (set_window_hscroll): New function, containing the old guts of
2284 Fset_window_hscroll. Return the clipped value.
2285 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2286 This avoids the need to check against PTRDIFF_MAX.
2288 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2290 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2292 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2294 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2296 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2297 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2298 since GCC 4.4.6 issues a bogus warning for them.
2300 Fix bugs in file timestamp newness comparisons.
2301 * fileio.c (Ffile_newer_than_file_p):
2302 * lread.c (Fload): Use full timestamp resolution of files,
2303 not just the 1-second resolution, so that files that are only
2304 slightly newer still count as newer.
2305 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2306 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2308 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2310 * fileio.c: Improve handling of file time marker. (Bug#11852)
2311 (special_mtime): New function.
2312 (Finsert_file_contents, Fverify_visited_file_modtime):
2313 Use it to set special mtime values consistently.
2315 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2317 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2318 marker for non-existing file. (Bug#11852)
2320 2012-07-03 Glenn Morris <rgm@gnu.org>
2322 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2323 and did not make it into globals.h).
2325 2012-07-03 Tom Tromey <tromey@redhat.com>
2327 * window.c (Fset_window_margins, Fset_window_fringes)
2328 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2329 * textprop.c (Fprevious_property_change): No longer static.

2352 * intervals.h: Remove EXFUNs.
2353 * fontset.h: Remove EXFUN.
2354 * font.h: Remove EXFUNs.
2355 * dosfns.c (system_process_attributes): Remove EXFUN.
2356 * keymap.h: Remove EXFUNs.

2371 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2372 values which aren't power of 2.
2373 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2374 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2377 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2379 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2381 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2383 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2385 * alloc.c (allocate_vector_block): Remove redundant
2386 calls to mallopt if DOUG_LEA_MALLOC is defined.
2387 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2388 avoid calls to mallopt if zero_vector is returned.
2390 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2392 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2393 is enabled, avoid dereferencing NULL current_sblock if
2396 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2398 Cleanup basic buffer management.
2399 * buffer.h (struct buffer): Change layout to use generic vector
2400 marking code. Fix some comments. Change type of 'clip_changed'
2401 to bitfield. Remove unused #ifndef old.
2402 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2403 (GET_OVERLAYS_AT): Fix indentation.
2404 (for_each_per_buffer_object_at): New macro.
2405 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2406 (Fbuffer_local_variables): Use it.
2407 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2408 * alloc.c (allocate_buffer): Adjust to match new layout of
2409 struct buffer. Fix comment.
2410 (mark_overlay): New function.
2411 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2412 Lisp area of struct buffer.
2413 (mark_object): Use it. Adjust marking of misc objects
2414 and related comments.
2416 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2418 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2419 wrapper that is not needed because the wrapped code is a no-op (zero
2420 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2421 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2423 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2425 * alloc.c (mark_buffer): Simplify. Remove prototype.
2426 (mark_object): Add comment. Reorganize marking of vector-like
2427 objects. Use CHECK_LIVE for all vector-like objects except buffers
2428 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2429 redundant calls to mark_vectorlike for bool vectors.
2431 2012-06-30 Glenn Morris <rgm@gnu.org>
2433 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2435 * epaths.in (PATH_SITELOADSEARCH): New.
2436 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2437 This is rather than relying on --enable-locallisppath elements
2438 having "site-lisp" in their names. (Bug#10208#25, 11658)
2440 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2442 * w32proc.c (sys_select): Accept and ignore one more argument.
2444 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2446 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2447 (pselect) [!MS_DOS]: Redirect to sys_select.
2449 * sysdep.c: Don't include dos.h and dosfns.h.
2451 * process.c (sys_select):
2452 * msdos.c (sys_select): Accept one more argument and ignore it.
2454 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2455 adapt data types and code to that.
2458 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2459 which clashes with the gnulib function of the same name.
2461 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2463 * font.c (font_style_to_value, font_style_symbolic)
2464 (font_prop_validate_style): Add type checks for values in
2467 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2469 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2472 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2474 * xdisp.c (try_window_id): Undo last change.
2476 * w32.c (getwd): Adjust commentary about startup_dir.
2477 (init_environment): Always call sys_access, even in non-MSVC
2478 builds. Don't chdir to the directory of the Emacs executable.
2479 This undoes code from 1997 which was justified by the need to
2480 "avoid conflicts when removing and renaming directories". But its
2481 downside was that every relative file name was being interpreted
2482 relative to the directory of the Emacs executable, which can never
2483 be TRT. In particular, it broke sys_access when called with
2484 relative file names.
2485 (sys_access): Map GetLastError to errno.
2487 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2489 * window.h (struct window): Change type of 'fringes_outside_margins'
2490 to bitfield. Fix comment. Adjust users accordingly.
2491 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2493 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2496 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2498 * gnutls.c (emacs_gnutls_handshake):
2499 Add QUIT to make the loop interruptible.
2501 2012-06-29 Glenn Morris <rgm@gnu.org>
2503 * charset.c (init_charset): Make lack of etc/charsets fatal.
2505 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2507 * editfns.c (region_limit): Fix type mismatch.
2509 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2511 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2512 undefined. Convert from xassert to eassert.
2513 * nsmenu.m: Convert from xassert to eassert.
2514 * nsterm.m: Likewise.
2516 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2518 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2520 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2522 Avoid integer overflow on scroll-left and scroll-right.
2523 * window.c (HSCROLL_MAX): New macro.
2524 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2525 overflow when requested scroll falls outside ptrdiff_t range.
2527 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2529 * window.h (struct window): Change type of 'hscroll',
2530 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2531 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2532 Adjust users accordingly.
2533 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2534 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2535 from EMACS_INT to ptrdiff_t.
2536 (make_window): Omit redundant initialization.
2538 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2542 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2544 * window.h (struct window): Change type of 'use_time' and
2545 'sequence_number' from Lisp_Object to int.

2555 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2556 adjust comments accordingly.

2607 avoid GCC warning about unused macro.
2609 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2611 * alloc.c (allocate_string): Omit intervals initialization.
2612 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2613 as in make_pure_string and make_pure_c_string.
2615 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2617 * alloc.c (allocate_string): Fix last change.
2619 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2669 * alloc.c: Remove build_string.
2670 * lisp.h: Define build_string as static inline. This provides
2671 a better opportunity to optimize away calls to strlen when the
2672 function is called with compile-time constant argument.
2673 * image.c (imagemagick_error): Convert to build_string.
2674 * w32proc.c (sys_spawnve): Likewise.
2675 * xterm.c (x_term_init): Likewise.
2677 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2679 Use sprintf return value instead of invoking strlen on result.
2680 In the old days this wasn't portable, since some sprintf
2681 implementations returned char *. But they died out years ago and
2682 Emacs already assumes sprintf returns int.
2683 Similarly for float_to_string.
2684 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2685 * ccl.c (ccl_driver):
2686 * character.c (string_escape_byte8):

2689 * print.c (print_object):
2690 * xdisp.c (message_dolog):
2691 * xfns.c (syms_of_xfns):
2692 Use sprintf or float_to_string result to avoid need to call strlen.
2693 * data.c (Fnumber_to_string):
2694 Use make_unibyte_string, since the string must be ASCII.
2695 * lisp.h, print.c (float_to_string): Now returns int length.
2696 * term.c (produce_glyphless_glyph):
2697 Use sprintf result rather than recomputing it.
2699 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2700 * Makefile.in (ALL_CFLAGS):
2701 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2707 strcasecmp if available.

2730 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2732 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2735 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2737 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2738 instead of truncating it to 63 (admittedly a generous limit).
2740 * process.c: Fix spelling and caps in comments.
2742 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2744 * emacs.c (setpgrp): Remove definition, unused.

2791 Remove unnecessary forward decls.
2793 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

2802 when time_t is unsigned and as wide as intmax_t.
2803 See <http://bugs.gnu.org/9000#51>.
2805 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2834 language ID in the event parameters.
2836 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2866 Don't assume EMACS_TIME and struct timeval are the same type.
2868 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2870 Support higher-resolution time stamps (Bug#9000).
2871 The time stamps are only nanosecond-resolution at the C level,
2872 since that's the best that any real-world system supports now.
2873 But they are picosecond-resolution at the Lisp level, as that's
2874 easy, and leaves room for future OS improvements.
2876 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2879 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2880 Don't get current time unless it's needed.
2882 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2883 now provides it if it's absent.
2884 (start_atimer): Port to higher-res time stamps.
2885 Check for time stamp overflow. Don't get current time more
2886 often than is needed.
2888 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2889 Include systime.h, not time.h.

2896 (struct image): Timestamp now has higher resolution.
2898 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2899 has at least microseconds now. All uses removed.
2900 (update_frame, update_single_window, update_window, update_frame_1)
2901 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2903 * editfns.c (time_overflow): Now extern.
2904 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2910 (make_time): Now static.
2911 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2912 Report an error if the time is invalid, rather than having the caller
2915 * fileio.c: Include <stat-time.h>
2916 (Fcopy_file): Copy higher-resolution time stamps.
2917 Prefer to set the time stamp via a file descriptor if that works.

2919 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2920 (Fvisited_file_modtime, Fset_visited_file_modtime):
2921 Support higher-resolution time stamps.
2923 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2925 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2927 * image.c (prepare_image_for_display, clear_image_cache)
2928 (lookup_image): Port to higer-resolution time stamps.
2930 * keyboard.c (start_polling, bind_polling_period):
2931 Check for time stamp overflow.
2932 (read_char, kbd_buffer_get_event, timer_start_idle)
2933 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2934 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2935 Port to higher-resolution time stamps. Do not assume time_t is signed.
2936 (decode_timer): New function. Timers are now vectors of length 9,
2937 not 8, to accommodate the picosecond component.
2938 (timer_check_2): Use it.
2940 * nsterm.m (select_timeout, timeval_subtract): Remove.
2941 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2942 as they're a bit more accurate and handle overflow better.
2943 (ns_select): Change prototype to be compatible with pselect.
2944 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2945 * nsterm.h (ns_select): Adjust prototype.
2947 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2948 us-resolution time stamps.
2949 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2951 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2953 * lisp.h (time_overflow): New decl.
2954 (wait_reading_process_output): First arg is now intmax_t, not int,
2955 to accommodate larger waits.
2957 * process.h (struct Lisp_Process.read_output_delay):
2958 Now counts nanoseconds, not microseconds.
2959 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2961 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2962 (wait_reading_process_output):
2963 Port to ns-resolution time stamps.
2964 (Faccept_process_output, wait_reading_process_output):
2965 Check for time stamp overflow. Do not assume time_t is signed.
2966 (select_wrapper): Remove; we now use pselect.
2967 (Fprocess_attributes): Now generates ns-resolution time stamps.
2969 * sysdep.c: Include utimens.h. Don't include utime.h
2970 or worry about struct utimbuf; gnulib does that for us now.
2971 (gettimeofday): Remove; gnulib provides a substitute.
2972 (make_timeval): New function.
2973 (set_file_times): Now sets ns-resolution time stamps.
2974 New arg FD; all uses changed.
2975 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2976 (system_process_attributes):
2977 Now returns ns-resolution time stamp. All uses changed.
2978 Check for time stamp overflow.
2980 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2981 provides a substitute now.
2983 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2984 since it guarantees struct timespec.
2985 (EMACS_TIME): Now struct timespec, so that we can support
2986 ns-resolution time stamps.
2987 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2988 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2989 (EMACS_USECS): Remove.
2990 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2991 so multiply the arg by 1000 before storing it.
2992 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2994 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2995 Port to ns-resolution time stamps.
2996 (EMACS_TIME_NEG_P): Remove; replaced by....
2997 (EMACS_TIME_SIGN): New macro.

2999 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3000 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3001 (make_timeval, make_lisp_time, decode_time_components): New decls.
3002 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3003 that it mishandled time_t overflow. You can't compare by subtracting!
3004 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3005 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3007 * term.c: Include <sys/time.h>.

3016 (w32_get_internal_run_time):
3017 Port to higher-resolution Emacs time stamps.
3018 (ltime): Now accepts single 64-bit integer, as that's more convenient
3021 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3023 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3024 for compatibility with pselect. Support ns-resolution time stamps.
3026 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3028 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3029 Check for time stamp overflow, and support ns-resolution time stamps.
3031 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3032 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3033 (timeval_subtract): Remove; no longer needed.
3034 (XTflash, XTring_bell, x_wait_for_event):
3035 Port to ns-resolution time stamps. Don't assume time_t is signed.
3037 2012-06-22 Chong Yidong <cyd@gnu.org>

3041 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3043 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3044 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3045 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3046 staticidx goes up to 1597 out of 1600 = 0x640.)
3048 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3050 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3051 Otherwise, the umask might be mistakenly 0 while handling input signals.

3073 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3075 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3076 since tty frames can be explicitly named.

3085 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3086 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3087 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3088 (METER_1, METER_2): Simplify.

3096 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3097 gets killed during executing of this function (Bug#11665).
3098 Try to always return Qt when the buffer has been actually killed.
3099 (Vkill_buffer_query_functions): In doc-string say that functions
3100 run by this hook should not change the current buffer.
3102 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3104 Fix recently-introduced process.c problems found by static checking.

3122 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3124 * lisp.h (eassert): Assume C89 or later.
3125 This removes the need for CHECK.
3126 (CHECK): Remove. Its comments about always evaluating its
3127 argument were confusing, as 'eassert' typically does not evaluate
3130 * coding.c (produce_chars): Use ptrdiff_t, not int.
3132 * xterm.c (x_draw_underwave): Check for integer overflow.
3133 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3227 If all the glyphs of the glyph row came from strings, and we have no
3228 cursor positioning clues, put the cursor on the first glyph of the

3272 * s/usg5-4-common.h (USG5_4): No longer define; unused.
3274 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
3276 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
3279 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
3281 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

3285 * frame.c (delete_frame): Remove outdated comment.
3286 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
3287 USE_LISP_UNION_TYPE.

3306 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
3307 * alloc.c (make_number) [!defined make_number]:

3310 (roundup_size): Verify that it is a power of 2.
3311 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
3312 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
3313 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
3314 -DUSE_LSB_TAG=0, to override the automatically-selected default.
3315 USE_LSB_TAG now is always defined to be either 0 or 1.
3317 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3318 code works fine either way, and efficiency is not a concern here,
3319 as the union type is for debugging, not for production.
3320 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3321 Use an inline function on all platforms when using the union type,
3322 since this is simpler and 'static inline' can be used portably
3324 (LISP_INITIALLY_ZERO): New macro.
3325 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3326 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3353 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
3354 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
3355 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

3395 dbus_type_is_basic if available.
3396 (xd_extract_signed, xd_extract_unsigned): Rename from
3397 extract_signed and extract_unsigned, respectively. Adapt callers.
3399 2012-06-09 Chong Yidong <cyd@gnu.org>

3408 * xdisp.c (vmessage): Treat frame message as multibyte.
3409 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
3410 would generate the diagnostic "Making \302\247 buffer-local while
3413 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3415 * dispnew.c (showing_window_margins_p): Undo last change, which

3429 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3431 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3433 * alloc.c (allocate_vectorlike): Fix last change.
3435 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
3437 Block-based vector allocation of small vectors.

3464 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3466 * doprnt.c (doprnt): Truncate multibyte char correctly.
3467 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3468 would mishandle a string argument "Xc" if X was a multibyte
3469 character of length 2: it would truncate after X's first byte
3470 rather than including all of X.
3472 2012-06-06 Chong Yidong <cyd@gnu.org>
3474 * buffer.c (word_wrap): Doc fix.

3523 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3524 Convert pctcpu and pctmem to Lisp float properly.
3525 Let the compiler fold better, as 100.0/0x8000 is exact.
3527 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3529 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3532 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3534 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3536 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3538 For a 'struct window', replace some Lisp_Object fields to
3539 bitfields where appropriate, remove unused fields.
3540 * window.h (struct window): Remove unused 'last_mark_x' and
3541 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3542 change it's type from Lisp_Object to bitfield.
3543 Change type of 'force_start', 'optional_new_start',
3544 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3545 fields from Lisp_Object to bitfield. Adjust users accordingly.
3547 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3549 Pacify gcc -Wdouble-precision when using Xaw.
3550 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3551 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3552 Use 'float' consistently, rather than 'float' in most places
3553 and 'double' in a couple of places.
3555 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3557 * xdisp.c (handle_stop): Detect whether we have overlay strings
3558 loaded by testing it->current.overlay_string_index to be
3559 non-negative, instead of checking whether n_overlay_strings is
3560 positive. (Bug#11587)
3562 2012-05-31 Chong Yidong <cyd@gnu.org>
3564 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3566 * doc.c (Fsubstitute_command_keys): Doc fix.
3568 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3570 * search.c (search_buffer): Remove calls to
3571 r_alloc_inhibit_buffer_relocation, as it is now called by
3572 maybe_unify_char, which was the cause of relocation of buffer text
3575 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3577 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3578 for the duration of call to load_charset, to avoid problems with
3579 callers of maybe_unify_char that access buffer text through C
3582 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3583 decrement the inhibition flag, instead of just setting or
3586 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3588 Remove obsolete '#define static' cruft.
3589 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3590 This #undef was "temporary" in 2000; it is no longer needed
3591 now that '#define static' has gone away.
3592 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3593 (gray_bitmap_bits): Remove; no longer needed.
3594 All uses replaced with definiens.
3595 * xterm.c: Include "bitmaps/gray.xbm".
3597 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3599 Clean up __executable_start, monstartup when --enable-profiling.
3600 The following changes affect the code only when profiling.
3601 * dispnew.c (__executable_start): Rename from safe_bcopy.
3602 Define only on platforms that need it.
3603 * emacs.c: Include <sys/gmon.h> when profiling.
3604 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3605 (__executable_start): Remove decl, since lisp.h does it now.
3606 (safe_bcopy): Remove decl; no longer has that name.
3607 (main): Coalesce #if into single bit of code, for simplicity.
3608 Cast pointers to uintptr_t, since standard libraries want integers

3635 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3637 Do not create empty overlays with the evaporate property (Bug#9642).
3638 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3639 Bug#9642, but explicitly check that the buffer the overlay would
3640 be moved to is live and rearrange lines to make sure that errors
3641 will not put the overlay in an inconsistent state.
3642 (Fdelete_overlay): Cosmetics.
3644 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3646 * w32term.c (my_bring_window_to_top): New function.
3647 (x_raise_frame): Use handle returned by DeferWindowPos, which

3658 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3660 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3661 This avoids undefined behavior that might cause the eassert
3662 to not catch an out-of-range value.
3664 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3666 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3676 when referring to sectname field in printf format.
3678 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3680 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3681 Only r_alloc_inhibit_buffer_relocation needed to be added;
3682 the others were already declared.
3684 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3685 before checking whether it's out of range. Put the check inside
3687 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3689 2012-05-27 Ken Brown <kbrown@cornell.edu>
3691 * callproc.c (Fcall_process): Restore a line that was accidentally
3692 commented out in the 2011-02-13 change (bug#11547).

3696 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3697 defined on ralloc.c.
3699 * buffer.c [REL_ALLOC]: Remove prototypes of
3700 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3701 they are now on lisp.h.
3703 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3705 * search.c (search_buffer): Use it to inhibit relocation of buffer
3706 text while re_search_2 is doing its job, because re_search_2 is
3707 passed C pointers to buffer text. (Bug#11519)
3709 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3712 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3713 state after an additional call to move_it_in_display_line_to, keep
3714 the values of it->max_ascent and it->max_descent found for the
3716 (pos_visible_p): Revert the comparison against bottom_y to what it
3717 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3720 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3722 Fix coding-related core dumps with gcc -ftrapv.
3723 The code was computing A - B, where A and B are pointers, and B is
3724 random garbage. This can lead to core dumps on platforms that
3725 have special pointer registers, and it also leads to core dumps on
3726 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3727 A - B only when B is initialized properly.
3728 * coding.c (coding_set_source, coding_set_destination): Return void.
3729 (coding_change_source, coding_change_destinations): New functions,
3730 with the old behaviors of coding_set_source and coding_set_destination.
3731 All callers that need an offset changed to use these new functions.
3733 2012-05-26 Glenn Morris <rgm@gnu.org>

3751 gen_help_event to produce help-echo message in the echo area.
3752 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3755 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>

3758 with GCC 4.7.0 on x86-64.
3760 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3762 * bidi.c (bidi_mirror_char): Revert last change: an int is
3763 definitely wide enough here.
3765 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3767 Fix integer width and related bugs (Bug#9874).

3779 Use int, not EMACS_INT, where int is wide enough.

3799 (Foverlay_recenter, last_overlay_modification_hooks_used)
3800 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3801 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3802 (validate_region): Omit unnecessary test for b <= e,
3803 since that's guaranteed by the previous test.
3804 (adjust_overlays_for_delete): Avoid pos + length overflow.
3805 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3806 (report_overlay_modification):
3807 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3808 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3817 not int, to avoid needless 32-bit limit on 64-bit hosts.
3818 (exec_byte_code): Use tighter memory-full test, one that checks
3819 for alloca overflow. Don't compute the address of the object just
3820 before an array, as that's not portable. Use EMACS_INT, not
3821 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3822 * callint.c (Fcall_interactively):
3823 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3835 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3836 (casify_object): Avoid integer overflow when overallocating buffer.
3837 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3840 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3841 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3842 integers are now checked earlier. All uses replaced with XINT.
3844 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3845 For CCL_MapSingle, check that content and value are in int range.
3846 (ccl_driver, Fregister_code_conversion_map):
3847 Check that Vcode_version_map_vector is a vector.
3848 (resolve_symbol_ccl_program): Check that vector header is in range.
3849 Always copy the vector, so that we can check its contents reliably
3850 now rather than having to recheck each instruction as it's being
3851 executed. Check that vector words fit in 'int'.
3852 (ccl_get_compiled_code, Fregister_ccl_program)
3853 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3854 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3855 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3856 contents are in range.
3857 (Fccl_execute_on_string): Check that status is in range.
3858 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3859 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3860 Accept and return EMACS_INT, not int, because callers can pass values

3866 (string_escape_byte8, Fget_byte):
3867 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3868 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3869 avoid mishandling large integers.
3870 * character.h: Adjust decls to match defn changes elsewhere.

3880 Don't rely on undefined behavior with signed left shift overflow.
3881 Don't assume unsigned int fits into fixnum, or that fixnum fits
3882 into unsigned int. Don't require max_code to be a valid fixnum;
3883 that's not true for gb10830 4-byte on a 32-bit host. Allow
3884 invalid_code to be a cons, for the same reason. Require code_offset
3885 to be a character. Avoid int overflow if max_char is close
3887 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3888 this is intended anyway and avoids some undefined behavior.
3889 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3890 INDEX_TO_CODE_POINT, as that's what it expects.
3891 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3892 * charset.h (DECODE_CHAR): Return int, not unsigned;
3893 this is what was intended anyway, and it avoids undefined behavior.
3894 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3895 integer-overflow issues.
3896 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3897 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3898 where the argument is EMACS_INT, and this behavior is not intended.
3899 * chartab.c (Fmake_char_table, Fset_char_table_range)
3900 (uniprop_get_decoder, uniprop_get_encoder):
3901 Don't assume fixnum fits in int.
3902 * cmds.c (move_point): New function, that does the gist of
3903 Fforward_char and Fbackward_char, but does so while checking
3904 for integer overflow more accurately.
3905 (Fforward_char, Fbackward_char): Use it.
3906 (Fforward_line, Fend_of_line, internal_self_insert)
3907 (internal_self_insert):
3908 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4689 2012-05-14 Glenn Morris <rgm@gnu.org>
4691 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4692 Put "libexec" before "bin", for the sake of init_callproc_1.
4694 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4696 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

4699 (report_error, report_error_1, make_hdr, copy_sym)
4700 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4701 Make arguments const char *, not char *, to avoid violations of C
4702 standard and to fix some AIX warnings reported by Gilles Pion.
4704 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4706 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4707 already have overlays loaded.
4708 (handle_single_display_spec): Before returning without displaying
4709 fringe bitmap, synchronize the bidi iterator with the main display
4710 iterator, by calling iterate_out_of_display_property.
4711 (iterate_out_of_display_property): Detect buffer iteration by
4712 testing that it->string is a Lisp string.
4713 (get_next_display_element): When the current object is exhausted,
4714 and there's something on it->stack, call set_iterator_to_next to
4715 proceed with what's on the stack, instead of returning zero.
4716 (set_iterator_to_next): If called at the end of a Lisp string,
4717 proceed to consider_string_end without incrementing string
4718 position. Don't increment display vector index past the end of
4719 the display vector. (Bug#11417)
4720 (pos_visible_p): Don't report a position visible when move_it_to
4721 stopped at the last line of window, which happens to be scanned
4722 backwards by the bidi iteration. (Bug#11464)
4724 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4726 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4727 and right-margin display specs even if the spec is invalid or we
4728 are on a TTY, and thus unable to display on the fringes.
4729 That's because the text with the property will not be displayed anyway,
4730 so we need to signal to the caller that this is a "replacing"
4731 display spec. This fixes display when the spec is invalid or we
4734 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4736 * unexaix.c (make_hdr): Fix typo in prototype.
4737 This bug broke the build on AIX. Problem reported by Gilles Pion.
4739 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4741 * keyboard.c (kbd_buffer_get_event): Read special events also in
4742 batch mode. (Bug#11415)
4744 2012-05-12 Glenn Morris <rgm@gnu.org>

4752 2012-05-12 Glenn Morris <rgm@gnu.org>
4754 * Makefile.in (MKDIR_P): New, set by configure.
4755 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4757 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

4767 Update dependencies.
4769 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4771 * xgselect.c (xg_select): Put maxfds+1 into a var.
4772 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4774 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4776 2012-05-10 Dave Abrahams <dave@boostpro.com>
4778 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4779 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4781 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4783 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4784 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4785 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4786 Initialize xd_registered_buses.
4788 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4790 Untag more efficiently if USE_LSB_TAG.
4791 This is based on a proposal by YAMAMOTO Mitsuharu in
4792 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4793 For an admittedly artificial (nth 8000 longlist) benchmark on
4794 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4795 Emacs's overall text size by 1%.
4796 * lisp.h (XUNTAG): New macro.
4797 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4798 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4799 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4800 * eval.c (Fautoload):
4801 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4802 * frame.h (XFRAME): Use XUNTAG.
4804 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4805 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4806 Remove unportable assumptions about print widths of types like
4808 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4809 intptr_t when converting between pointer and integer, to avoid GCC
4810 warnings about wrong width.
4812 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4814 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4815 stack for each reader_thread, instead of defaulting to 8MB
4816 determined by the linker. This avoids failures in creating
4817 subprocesses on Windows 7, see the discussion in this thread:
4818 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4820 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4822 Fix up display of the *Minibuf-0* buffer in the mini window.
4823 * keyboard.c (read_char): Don't clear the echo area if there's no
4825 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4826 contents of *Minibuf-0*) if there's no message displayed in its stead.
4828 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4830 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4833 2012-05-06 Chong Yidong <cyd@gnu.org>
4835 * lisp.mk (lisp): Update.
4837 2012-05-05 Jim Meyering <meyering@redhat.com>
4839 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4841 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4843 * data.c (PUT_ERROR): New macro.
4844 (syms_of_data): Use it. Add new error type `user-error'.
4845 * undo.c (user_error): New function.
4846 (Fprimitive_undo): Use it.
4847 * print.c (print_error_message): Adjust print style for `user-error'.
4848 * keyboard.c (user_error): New function.
4849 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4851 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4853 Do not limit current-time-string to years 1000..9999.
4854 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4855 (Fcurrent_time_string): Support any year that is supported by the
4856 underlying localtime representation. Don't use asctime, as it
4857 has undefined behavior for years outside the range -999..9999.
4859 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4861 Fix race conditions involving setenv, gmtime, localtime, asctime.
4862 Without this fix, interrupts could mess up code that uses these
4863 nonreentrant functions, since setting TZ invalidates existing
4864 tm_zone or tzname values, and since most of these functions return
4865 pointers to static storage.
4866 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4867 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4868 Grow the critical sections to include not just invoking
4869 localtime/gmtime, but also accessing these functions' results
4870 including their tm_zone values if any, and any related TZ setting.
4871 (format_time_string): Last arg is now struct tm *, not struct tm **,
4872 so that the struct tm is saved in the critical section.
4873 All callers changed. Simplify allocation of initial buffer, partly
4874 motivated by the fact that memory allocation needs to be outside
4875 the critical section.
4877 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4879 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4880 with RESET_INTERVAL.
4882 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4883 Remove duplicated buffer name initialization.
4885 2012-05-02 Jim Meyering <jim@meyering.net>
4887 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4889 * xfns.c (x_window): Use xstrdup (Bug#11375).
4891 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4893 * xdisp.c (pos_visible_p): If already at a newline from the
4894 display string before the 'while' loop, don't walk back the glyphs
4895 from it3.glyph_row. Solves assertion violation when the display
4896 string begins with a newline (egg.el). (Bug#11367)
4898 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4900 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4903 2012-05-01 Glenn Morris <rgm@gnu.org>
4905 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4906 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4907 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4908 All were removed before 23.1.
4910 * dispnew.c: Remove HAVE_LIBNCURSES test;
4911 it is always true on relevant platforms.
4913 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4914 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4916 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4918 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4920 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4921 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4924 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4926 Do not avoid creating empty evaporating overlays (Bug#9642).
4927 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4928 That is, do not delete an evaporating overlay if it becomes
4929 empty after its bounds are adjusted to fit within its buffer.
4930 This fix caused other problems, and I'm reverting it until we get
4931 to the bottom of them.
4933 2012-04-27 Chong Yidong <cyd@gnu.org>
4935 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4937 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4939 * xdisp.c (pos_visible_p): If the window start position is beyond
4940 ZV, start the display from buffer beginning. Prevents assertion
4941 violation in init_iterator when the minibuffer window is scrolled
4944 * window.c (window_scroll_pixel_based): Likewise.
4946 2012-04-27 Chong Yidong <cyd@gnu.org>
4948 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4950 2012-04-27 Glenn Morris <rgm@gnu.org>
4952 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4953 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4955 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4957 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4958 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4960 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4962 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4963 display element, check also the underlying string or buffer
4964 character. (Bug#11341)
4966 * w32menu.c: Include w32heap.h.
4967 (add_menu_item): If the call to AppendMenuW (via
4968 unicode_append_menu) fails, disable Unicode menus only if we are
4969 running on Windows 9X/Me.
4971 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4973 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4974 (xgetint): Add missing shift for LSB tags.
4976 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4978 * keyboard.c (read_char): Don't wipe echo area for select window
4979 events: These might get delayed via `mouse-autoselect-window'
4982 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4984 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4985 manipulation of :loaded-from data.
4987 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4989 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4990 now a cons (bug#11311).
4992 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4994 Do not create empty overlays with the evaporate property (Bug#9642).
4995 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4996 if it becomes empty after its bounds are adjusted to fit within
4997 its buffer. Without this fix, in a nonempty buffer (let ((o
4998 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4999 yields an empty overlay that has the evaporate property, which is
5000 not supposed to happen.
5002 Fix minor GTK3 problems found by static checking.
5003 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5004 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5005 (struct _EmacsFixedClass, emacs_fixed_get_type):

5018 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5020 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5022 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5023 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5024 (__malloc_size_t, __malloc_ptrdiff_t):
5025 Remove. All uses removed, replaced by the definiens if needed,
5026 since we can assume C89 or better now.

5037 Define using prototypes, not old style.
5038 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5039 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

5117 * sysdep.c [__FreeBSD__]: Minor cleanups.
5118 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5119 Use Emacs indenting style more consistently. Avoid some casts.
5120 Use 'double' consistently rather than mixing 'float' and 'double'.
5122 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5124 * sysdep.c (list_system_processes, system_process_attributes):

5140 (print_object): Check for cycles even when print-circle is nil and
5141 print-gensym is t, but only check print_depth if print-circle is nil.
5143 2012-04-20 Chong Yidong <cyd@gnu.org>
5145 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5146 set the status to "failed" and ensure that sentinel is run.

5201 New extern decls, to avoid calling undeclared functions.
5202 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5203 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5204 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

5206 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5207 Remove one incorrect comment and fix another.

5221 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5222 Remove decls. This fixes an "It stinks!".
5224 * alloc.c (which_symbols): Fix alignment issue / type clash.
5226 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5228 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5246 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5247 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5248 no longer the default.
5249 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5251 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5253 * lread.c (lisp_file_lexically_bound_p):

5274 2012-04-11 Daniel Colascione <dancol@dancol.org>
5276 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5277 against is gone. It's better to use vfork now so that when Cygwin
5278 gains a new, working vfork, we use it automatically (bug#10398).
5280 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5309 Pass EMACS rather than BUILT_EMACS.
5311 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5313 * process.c (make_process):
5314 * process.h: Add integer `gnutls_handshakes_tried' member to
5317 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5318 Add convenience `GNUTLS_LOG2i' macro.
5320 * gnutls.c (gnutls_log_function2i): Convenience log function.
5321 (emacs_gnutls_read): Use new log functions,
5322 `gnutls_handshakes_tried' process member, and
5323 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5324 attempts per process (connection).
5326 2012-04-09 Chong Yidong <cyd@gnu.org>
5328 * eval.c (Fuser_variable_p, user_variable_p_eh)

5333 * minibuf.c (Fread_variable): Callers changed.
5335 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5337 * xdisp.c (set_cursor_from_row): If the display string appears in
5338 the buffer at position that is closer to point than the position
5339 after the display string, display the cursor on the first glyph of
5340 the display string. Fixes cursor display when a 'display' text
5341 property immediately follows invisible text. (Bug#11094)
5343 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5345 composite.c: use 'double' consistently
5346 * composite.c (get_composition_id): Use 'double' consistently
5347 instead of converting 'float' to 'double' and vice versa; this is
5348 easier to understand and avoids a GCC warning.
5350 2012-04-09 Glenn Morris <rgm@gnu.org>
5352 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5353 preparation for dumping it with emacs. (Bug#4789)
5354 (leimdir): New variable.
5355 ($(leimdir)/leim-list.el): New rule.

5372 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5374 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5375 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5376 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5377 objects, as mark_maybe_pointer will catch them otherwise.
5378 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5379 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5381 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5383 Fix typo that broke non-Windows builds.
5384 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5390 * makefile.w32-in (OBJ2): Add xml.$(O).
5391 (GLOBAL_SOURCES): Add xml.c.
5392 ($(BLD)/xml.$(O)): New dependency list.
5394 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5395 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5396 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5397 [!WINDOWSNT]: New macros.
5398 (init_libxml2_functions, libxml2_loaded_p): New functions.
5399 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5400 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5401 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5402 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5404 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5405 Call init_libxml2_functions before calling libxml2 functions.
5406 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5408 * emacs.c: Don't include libxml/parser.h.
5409 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5410 xmlCleanupParser directly.
5412 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5414 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5416 * indent.c (Fvertical_motion): If there is a display string at
5417 point, use it.vpos to compute how many lines to backtrack after
5418 move_it_to point. (Bug#11133)
5420 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5422 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5423 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5424 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5425 macros related to unification of CJK characters. For the details,
5426 see the discussion following the message here:
5427 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5429 2012-04-04 Chong Yidong <cyd@gnu.org>
5431 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5433 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5435 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5436 instead of alloca. (Bug#11138)
5438 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5440 * w32menu.c (is_simple_dialog): Properly check lisp types.
5443 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5445 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5446 position we get to after a call to move_it_to fails the
5447 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5448 only if we wind up in a string from display property. (Bug#11063)
5450 * window.c (Fdelete_other_windows_internal): Invalidate the row
5451 and column information about mouse highlight, so that redisplay
5452 restores it after reallocating the glyph matrices. (Bug#7464)
5454 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5455 string comes from a `display' text property, use the buffer
5456 position of that property as if we actually saw that position in
5458 (move_it_by_lines): Remove the assertion that
5459 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5460 violated when there's a before-string at the beginning of a line.
5463 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5465 * xdisp.c (append_space_for_newline): If the default face was
5466 remapped, use the remapped face for the appended newline.
5467 (extend_face_to_end_of_line): Use the remapped default face for
5468 extending the face to the end of the line.
5469 (display_line): Call extend_face_to_end_of_line when the default
5470 face was remapped. (Bug#11068)
5472 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5474 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5476 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5478 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5480 2012-03-27 Glenn Morris <rgm@gnu.org>
5482 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5485 2012-03-26 Kenichi Handa <handa@m17n.org>
5487 * dispextern.h (struct glyph): Fix previous change. Change the
5488 bit length of glyphless.ch to 25 (Bug#11082).
5490 2012-03-26 Chong Yidong <cyd@gnu.org>
5492 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5493 (command_loop_1): Use it; inhibit selection update for
5494 handle-select-window too (Bug#8996).
5496 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5498 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5500 2012-03-25 Kenichi Handa <handa@m17n.org>
5502 * dispextern.h (struct glyph): Change the bit length of
5503 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5505 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5507 * s/ms-w32.h (tzname): Include time.h before redirecting to
5508 _tzname. Fixes the MSVC build. (Bug#9960)
5510 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5512 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5515 * xterm.c (XTread_socket): Only modify handling_signal if
5516 !SYNC_INPUT. (Bug#11080)
5518 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5520 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5521 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5522 when fetching a multibyte character consumes more bytes than
5523 CHAR_BYTES returns, due to unification of CJK characters in
5524 string_char. (Bug#11073)
5526 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5528 * process.c (wait_reading_process_output): Handle pty disconnect
5529 by refraining from sending oneself a SIGCHLD (bug#10933).
5531 2012-03-22 Chong Yidong <cyd@gnu.org>
5533 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5535 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5536 Mark string as coming from a prefix property.
5537 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5538 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5540 2012-03-21 Chong Yidong <cyd@gnu.org>
5542 * xfaces.c (Vface_remapping_alist): Doc fix.
5544 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5546 * w32proc.c (Fw32_set_console_codepage)
5547 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5550 2012-03-20 Chong Yidong <cyd@gnu.org>
5552 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5553 to reflect default non-nil value of redisplay-dont-pause.
5555 2012-03-19 Kenichi Handa <handa@m17n.org>
5557 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5558 it fit in a valid range (Bug#11003).
5560 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5562 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5563 that is not from display property, accept the row as a "cursor
5564 row" if one of the string's character has a non-nil `cursor'
5565 property. Fixes cursor positioning when there are newlines in
5566 overlay strings, e.g. in icomplete.el. (Bug#11035)
5568 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5570 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5572 2012-03-12 Chong Yidong <cyd@gnu.org>
5574 * eval.c (inhibit_lisp_code): Rename from
5575 inhibit_window_configuration_change_hook; move from window.c.
5577 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5578 * window.c (run_window_configuration_change_hook)
5579 (syms_of_window): Callers changed.
5581 2012-03-11 Chong Yidong <cyd@gnu.org>

5590 is visible (Bug#10955).
5592 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5594 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5596 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5598 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5599 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5602 2012-03-03 Glenn Morris <rgm@gnu.org>
5604 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5606 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5608 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5609 position past the first glyph_row that ends at ZV. (Bug#10902)
5610 (redisplay_window, next_element_from_string): Fix typos in
5612 (redisplay_window): Pass to move_it_vertically the margin in
5613 pixels, not in screen lines.
5615 2012-03-02 Glenn Morris <rgm@gnu.org>
5617 * buffer.c (buffer-list-update-hook): Doc fix.
5619 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5621 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5622 push_it before setting up the iterator for the first overlay
5623 string, even if we have an empty string loaded.
5624 (next_overlay_string): If there's an empty string on the iterator
5625 stack, pop the stack. (Bug#10903)
5627 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5629 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5630 Suggested by Stefan Monnier in
5631 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5632 * alloc.c (widen_to_Lisp_Object): New static function.
5633 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5634 and widening them to Lisp_Objects. This would work even if
5635 USE_LSB_TAG is defined and wide integers are used, which might
5636 happen in a future version of Emacs.
5638 2012-02-25 Chong Yidong <cyd@gnu.org>
5640 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5643 * xselect.c (Fx_selection_exists_p): Doc fix.
5644 (x_clipboard_manager_save_all): Print an informative message
5645 before saving to clipboard manager.
5647 2012-02-24 Chong Yidong <cyd@gnu.org>
5649 * keyboard.c (process_special_events): Handle all X selection
5650 requests in kbd_buffer, not just the next one (Bug#8869).

5655 call when setting menu-bar-lines and tool-bar-lines parameters.
5656 (unwind_create_frame_1): New helper function.
5658 * window.c (inhibit_window_configuration_change_hook): New var.
5659 (run_window_configuration_change_hook): Obey it.
5660 (syms_of_window): Initialize it.
5662 2012-02-22 Chong Yidong <cyd@gnu.org>

5677 when computing $valmask.
5679 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5680 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5681 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5682 It's useless in that case, and it can cause problems on hosts
5683 that allocate halves of EMACS_INT values separately.
5684 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5685 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5686 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5687 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5688 it avoids undefined behavior on hosts where shifting right by more
5689 than the word width has undefined behavior.
5691 2012-02-19 Chong Yidong <cyd@gnu.org>
5693 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5694 (Funhandled_file_name_directory, Ffile_name_as_directory)

5697 return values (Bug#10845).
5699 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5701 * .gdbinit (pitx): Fix incorrect references to fields of the

5711 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5713 2012-02-15 Chong Yidong <cyd@gnu.org>
5715 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5716 marked as special. Also, starting docstrings with * is obsolete.

5731 2012-02-12 Chong Yidong <cyd@gnu.org>
5733 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5734 as that creates a dangerous corner case.
5736 * window.c (Fdelete_window_internal): Invalidate the mouse
5737 highlight (Bug#9904).
5739 2012-02-12 Glenn Morris <rgm@gnu.org>

5742 (Fx_get_selection_internal, Fx_disown_selection_internal)
5743 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5744 * nsselect.m (Fx_own_selection_internal)
5745 (Fx_disown_selection_internal, Fx_selection_exists_p)
5746 (Fx_selection_owner_p, Fx_get_selection_internal):
5747 Sync docs and argument specs with the xselect.c versions.
5749 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

5769 2012-02-07 Chong Yidong <cyd@gnu.org>
5771 * buffer.c (Fbuffer_local_variables)
5772 (buffer_lisp_local_variables): Handle unbound vars correctly;
5773 don't let Qunbound leak into Lisp.
5775 2012-02-07 Glenn Morris <rgm@gnu.org>
5777 * image.c (Fimagemagick_types): Doc fix.
5779 * image.c (imagemagick-render-type): Change it from a lisp object
5780 to an integer. Move the doc here from the lisp manual.

6316 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Ensure ROW's
6317 attributes are tested _before_ calling verify_row_hash, to protect
6318 against GCC re-ordering of the tests. (Bug#10164)
6320 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>
6322 * xterm.h (struct x_output): net_wm_state_hidden_seen is new.

6341 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
6342 of scroll runs so as to avoid assigning disabled bogus rows and
6343 unnecessary graphics copy operations.
6345 2011-11-27 Eli Zaretskii <eliz@gnu.org>
6347 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

6354 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6355 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
6356 this macro definition.

6383 * xdisp.c (redisplay_window): If cursor row is not fully visible
6384 after recentering, and scroll-conservatively is set to a large
6385 number, scroll window by a few more lines to make the cursor fully
6386 visible and out of scroll-margin. (Bug#10105)
6387 (start_display): Don't move to the next line if the display should
6388 start at a newline that is part of a display vector or an overlay

6471 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6472 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6473 is set, removing the need for VIRT_ADDRESS_VARIES.
6474 (PURE_P): Use a more-efficient implementation that needs just one
6475 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6476 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6477 to 4 (xorl, subq, cmpq, setbe).
6478 * alloc.c (pure): Always extern now, since that's the
6479 VIRT_ADDR_VARIES behavior.
6480 (PURE_POINTER_P): Use a single comparison, not two, for
6481 consistency with the new puresize.h.
6482 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6483 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6489 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6490 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6491 behave as if the cursor position were at the window margin.
6493 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6494 and the cursor position is out of bounds, behave as if the cursor
6495 position were at the window margin. (Bug#10075)
6497 2011-11-18 Chong Yidong <cyd@gnu.org>
6499 * window.c (Fwindow_combination_limit): Make first argument

6521 compute_line_metrics.
6522 (compute_line_metrics): Call row_hash, instead of computing the
6525 * dispnew.c (verify_row_hash): Call row_hash for computing the
6526 hash code of a row, instead of duplicating code from xdisp.c.
6528 * dispextern.h (row_hash): Add prototype.
6530 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6532 * frame.c (delete_frame): Don't delete the terminal when the last

6555 (Fset_window_nest): Rename to Fset_window_combination_limit.
6556 (Vwindow_nest): Rename to Vwindow_combination_limit.
6557 (recombine_windows, make_parent_window, make_window)
6558 (Fsplit_window_internal, saved_window)
6559 (Fset_window_configuration, save_window_save): Rename all
6560 occurrences of window_nest to window_combination_limit.
6562 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6564 * image.c (imagemagick_load_image): Fix typo.
6566 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6568 * xdisp.c (display_line): Move the call to
6569 highlight_trailing_whitespace before the call to
6570 compute_line_metrics, since the latter needs to see the final
6571 faces of all the glyphs to compute ROW's hash value.
6572 Fixes assertion violations in row_equal_p. (Bug#10035)
6574 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6576 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6581 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6582 with user-defined heap size. Bump the default size of the temacs
6583 heap to 27MB, to avoid memory warning when running temacs.
6584 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6586 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6633 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6635 Avoid some portability problems by eschewing 'extern inline' functions.
6636 The trivial performance wins aren't worth the portability hassles; see
6637 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6639 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6641 (window_box_right, window_box_right_offset): Undo previous change,
6642 by removing the "extern"s.
6643 * intervals.c (adjust_intervals_for_insertion)
6644 (adjust_intervals_for_deletion): Undo previous change,
6645 making these static again.
6646 (offset_intervals, temp_set_point_both, temp_set_point)
6647 (copy_intervals_to_string): No longer inline.
6648 * xdisp.c (window_text_bottom_y, window_box_width)

6687 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6688 This is also needed for porting to any host where GC_MARK_STACK is
6689 not GC_MAKE_GCPROS_NOOPS.
6690 (which_symbols): Use it.
6692 2011-11-07 Kenichi Handa <handa@m17n.org>

6705 * xmenu.c (cleanup_widget_value_tree): New function.
6706 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6713 (window_box_width, window_box_left, window_box_left_offset)
6714 (window_box_right, window_box_right_offset): Declare extern.
6715 Otherwise, these inline functions do not conform to C99 and
6716 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6717 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6718 * intervals.c (adjust_intervals_for_insertion)
6719 (adjust_intervals_for_deletion): Now extern, because otherwise the
6720 extern inline functions 'offset_intervals' couldn't refer to it.
6721 (static_offset_intervals): Remove.
6722 (offset_intervals): Rewrite using the old contents of
6723 static_offset_intervals. The old version didn't conform to C99
6724 because an extern inline function contained a reference to an
6725 identifier with static linkage.
6727 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6729 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6747 (Fwindow_vscroll): Doc fix.
6748 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6749 argument, since it makes no sense to pass a live window and for
6750 consistency with window-child.

6777 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
6778 (unwind_create_frame): New function (Bug#9943).

6831 * xdisp.c (note_mouse_highlight): If either of
6832 previous/next-single-property-change returns nil, treat that as
6833 the beginning or the end of the buffer. (Bug#9955)
6835 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>

6857 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6858 Don't stop backward scan on the continuation glyph, even though
6859 its CHARPOS is positive.
6860 (mouse_face_from_buffer_pos, note_mouse_highlight):
6861 Rename cover_string to disp_string.
6863 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6865 * window.c (temp_output_buffer_show): Don't use
6866 Vtemp_buffer_show_specifiers.
6867 (Vtemp_buffer_show_specifiers): Remove unused variable.
6869 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6871 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6872 past the beginning of the current glyph matrix.

6897 so that this new function doesn't get optimized away by a
6898 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6900 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6902 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6904 2011-10-29 Eli Zaretskii <eliz@gnu.org>

6923 Not clear what it was for, and it causes various bugs. (Bug#9839)
6925 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6927 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6928 possible random value that matches one of those tested as
6929 condition to clear the mouse face.
6931 2011-10-28 Chong Yidong <cyd@gnu.org>
6933 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

6950 <oslsachem@gmail.com> for helping to debug this.
6952 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6953 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6954 (g_b_init_get_glyph_outline_w): New static variables.
6955 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)

6957 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6958 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6960 (w32font_open_internal, compute_metrics):
6961 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6962 instead of calling the "wide" APIs directly.
6964 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6966 * w32.h (syms_of_w32font): Add prototype.
6968 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6970 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6971 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6972 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

6980 non-NULL, regardless of GNUTLS_INITSTAGE.
6981 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

7004 * w32fns.c (w32_default_color_map): New function,
7005 extracted from Fw32_default_color_map.
7006 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
7008 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
7010 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
7012 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
7014 * keyboard.c (test_undefined): New function (bug#9751).
7015 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7017 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7019 * sysdep.c (init_sys_modes): Fix the check for the controlling
7020 terminal (Bug#6649).
7022 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7024 * dispextern.h (struct bidi_it): New member next_en_type.
7026 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7027 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7028 current character, check also for next_en_type being WEAK_EN.
7029 (bidi_resolve_weak): Don't enter the expensive loop if the current
7030 position is before next_en_pos. Record the bidi type of the first
7031 non-ET, non-BN character we find, in addition to its position.
7032 (bidi_level_of_next_char): Invalidate next_en_type when
7033 next_en_pos is over-stepped.
7035 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7037 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7038 * editfns.c: Rewrite current-time-zone so that it invokes
7039 the equivalent of (format-time-string "%Z") to get the time zone name.
7040 This fixes a bug when the time zone name contains characters that
7041 need converting from the system time locale to Emacs internal format.
7042 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7043 that patch fixed format-time-string to do the conversion, but
7044 I forgot to fix current-time-zone.
7045 (format_time_string): New function, containing most of
7046 what Fformat_time_string used to contain.
7047 (Fformat_time_string): Rewrite in terms of format_time_string.
7048 This doesn't change this function's behavior.
7049 (current-time-zone): Rewrite to use format_time_string.
7050 This fixes the bug reported by Michael Schierl in
7051 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7052 Jason Rumney's 2007-06-07 change worked around this bug, but
7054 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7056 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7058 * xdisp.c (start_display): If the character at POS is displayed
7059 via a display vector, reset IT->current.dpvec_index to zero.
7060 (try_window_reusing_current_matrix): If a line ends in a display
7061 vector or the next line starts in a display vector, continue
7062 redrawing the window even though the character position of
7063 start_row was reached.
7066 2011-10-18 Chong Yidong <cyd@gnu.org>
7068 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7069 with nobreak-char-display too.
7071 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7073 Fix part 3 of bug#9771.
7074 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7075 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7076 non-neutral characters if the current character is a paragraph
7077 separator (a.k.a. Newline). This avoids running the same
7078 expensive loop twice, once when we consume the preceding newline
7079 and the other time when the line actually needs to be displayed.
7080 Avoid the loop when we see neutrals on the base embedding level
7081 following a character whose directionality is the same as the
7082 paragraph's. This avoids running the expensive loop when a line
7083 ends in a long sequence of neutrals, like control characters.
7084 Add assertion against STRONG_AL type. Slightly rearrange code
7085 that determines the type of a neutral given the first non-neutral
7087 (bidi_level_of_next_char): Set next_en_pos to zero when
7088 invalidating its info.
7090 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7092 * xdisp.c (push_display_prop): Determine whether to record string
7093 or buffer position by IT->string, not by IT->method. Allow
7094 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7095 (move_it_vertically_backward): Don't look for character position
7096 immediately after the newline when in a continuation line.
7099 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7101 * window.c (coordinates_in_window): Rewrite and delabelize
7102 vertical border check. (Bug#5357) (Bug#9618)
7104 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7106 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7107 errors in XSetWindowBorder (bug#9310).
7109 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7111 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7112 avoid crash when xmalloc overrun checking is enabled.
7114 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7116 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7117 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7118 cursor motion with <left> and <right> arrow keys.
7120 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7121 some callers set that themselves.
7123 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7125 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7126 display string and the previous row comes from the same string and
7127 is empty. (Bug#9739) (Bug#9738)
7129 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7131 * doc.c (get_doc_string): Encode file name (bug#9735).
7133 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7135 * bidi.c (bidi_level_of_next_char):
7136 * xdisp.c (get_visually_first_element): Remove old incorrect
7137 comments regarding the Unicode Line Separator character.
7139 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7141 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7143 * alloc.c (Fgc_status): Do not access beyond zombies array
7144 boundary if nzombies > MAX_ZOMBIES.
7145 * alloc.c (dump_zombies): Add missing format specifier.
7147 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7149 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7150 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7152 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7153 Some packages use them to denote characters with modifiers.
7155 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7157 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7158 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7159 matching a pp-number. Rename parameter var to var1.
7161 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7163 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7165 2011-10-08 Glenn Morris <rgm@gnu.org>
7167 * callint.c (Fcall_interactively): Give a more explicit error for the
7168 'c' case with a non-character input. (Bug#8479)
7170 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7172 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7174 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7175 lines that are hscrolled on the left.
7177 * dispnew.c (buffer_posn_from_coords): Account for a possible
7178 presence of header-line. (Bug#4426)
7180 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7182 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7183 Don't advertise functionality which we discourage or doesn't work.
7185 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7187 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7188 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7189 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7190 this makes Emacs dump core during garbage collection on rare
7191 occasions. sizeof is obviously inferior to offsetof here, so
7192 stick with offsetof.
7193 (GC_POINTER_ALIGNMENT): New macro.
7194 (mark_memory): Omit 3rd (offset) arg; caller changed.
7195 Don't assume EMACS_INT alignment is the same as pointer alignment.
7197 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7199 * keyboard.c (read_key_sequence_remapped): New var.
7200 (read_key_sequence): Compute remapping in the right buffer.
7201 (command_loop_1): Use read_key_sequence's remapping directly.
7203 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7205 * dired.c (file_name_completion): Don't expand file name.
7206 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7207 before checking file name handler.
7209 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7210 they've been requested explicitly (bug#9591).
7212 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7214 * keymap.c (Fsingle_key_description): Use make_specified_string
7215 instead of build_string to build string from push_key_description.
7218 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7220 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7221 This fixes a Y2038 bug on 64-bit hosts.
7222 * buffer.c (reset_buffer):
7223 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7224 (Fclear_buffer_auto_save_failure):
7225 Use 0, not -1, to represent an unset failure time, since time_t
7226 might not be signed.
7228 Remove dependency on glibc malloc internals.
7229 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7230 Move back here from lisp.h, but with their new implementations.
7231 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7232 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7233 * charset.c (charset_table_init): New static var.
7234 (syms_of_charset): Use it instead of xmalloc. This removes a
7235 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7236 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7237 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7238 Move back to alloc.c.
7239 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7240 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7242 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7244 * nsterm.m (windowDidResize): Call x_set_window_size only when
7245 ns_in_resize is true. Otherwise set pixelwidth/height and
7246 call change_frame_size (Bug#9628).

7250 Port --enable-checking=all to Fedora 14 x86-64.
7251 * charset.c (syms_of_charset): Also account for glibc malloc's
7252 internal overhead when calculating the initial malloc maximum.
7254 Port --enable-checking=all to Fedora 14 x86.
7255 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7257 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7258 (overrun_check_realloc, overrun_check_free):
7259 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7260 That way, xmalloc returns a properly-aligned pointer even if
7261 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7262 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7263 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7264 into account when calculating the initial malloc maximum.
7265 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7266 Move here from alloc.c, so that charset.c can use it too.
7267 Properly align; the old code wasn't right for common 32-bit hosts
7268 when configured with --enable-checking=all.
7269 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7270 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7272 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7274 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7277 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7279 * xdisp.c (compute_display_string_end): If there's no display
7280 string at CHARPOS, return -1.
7282 * bidi.c (bidi_fetch_char): When compute_display_string_end
7283 returns a negative value, treat the character as a normal
7284 character not covered by a display string. (Bug#9624)
7286 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7288 * lread.c (Fread_from_string): Fix typo in docstring.
7290 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7292 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7293 newline, reseat the iterator instead of bidi-iterating there one
7294 character at a time. (Bug#9610)
7295 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7296 TO_CHARPOS if the bidi iterator is at base embedding level.
7298 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7300 * lread.c (readevalloop): Use correct code for NBSP.
7301 (read1): Likewise. (Bug#9608)
7303 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7305 * dbusbind.c (Fdbus_register_signal): When service is not
7306 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7308 2011-09-25 Glenn Morris <rgm@gnu.org>
7310 * buffer.c (truncate-lines): Doc fix.
7312 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7314 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7315 (Fset_window_next_buffers): Doc fix.
7317 2011-09-24 Glenn Morris <rgm@gnu.org>
7319 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7321 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7323 Fix minor problems found by static checking.
7324 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7325 * indent.c (Fvertical_motion): Fix == vs = typo.
7327 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7329 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7330 Default value is now t. Doc fix.
7332 * indent.c (Fvertical_motion): Compute and apply the overshoot
7333 logic when moving up, not only when moving down. Fix the
7334 confusing name and values of the it_overshoot_expected variable;
7335 logic changes accordingly. (Bug#9254) (Bug#9549)
7337 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7338 CHARPOS is covered by a display string which includes newlines.
7339 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7340 is covered by a display string with embedded newlines.
7342 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7344 * dbusbind.c (Fdbus_register_signal): Add match rule to
7345 Vdbus_registered_objects_table. (Bug#9581)
7346 (Fdbus_register_method, Vdbus_registered_objects_table):
7349 2011-09-24 Jim Meyering <meyering@redhat.com>
7351 do not ignore write error for any output size
7352 The previous change was incomplete.
7353 While it makes emacs --batch detect the vast majority of stdout
7354 write failures, errors were still ignored whenever the output size is
7355 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7356 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7357 && echo FAIL: ignored write error
7358 FAIL: ignored write error
7359 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7360 && echo FAIL: ignored write error
7361 FAIL: ignored write error
7362 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7364 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7366 * emacs.c (Fkill_emacs): In noninteractive mode exit
7367 non-successfully if a write error occurred on stdout. (Bug#9574)
7369 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7371 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7374 * dispextern.h (struct it): Update the comment documenting what
7377 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7379 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7380 a display string, extend search for cursor position to end of row.
7381 (find_row_edges): If the row ends in a newline from a display
7382 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7383 Handle the case of a display string with multiple newlines.
7384 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7385 non-empty line. Fixes confusing cursor motion with arrow keys at
7386 the beginning of a line that starts with whitespace.
7388 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7390 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7393 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7395 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7398 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7400 * xdisp.c (display_line): Record maximum and minimum buffer
7401 positions even if no glyphs were produced (e.g., by a zero-width
7402 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7403 buffer positions that will be removed from the glyph row because
7405 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7406 column is beyond frame width: don't subtract 1 "pixel" when
7407 computing width of the stretch.
7408 (reseat_at_next_visible_line_start): Undo the change made on
7409 2011-09-17 that saved paragraph information and restored it after
7410 the call to `reseat'. (Bug#9545)
7412 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7414 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7415 and turn window cursor on if cleared (Bug#9415).
7417 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7419 * search.c (boyer_moore): Take unibyte characters from pattern
7420 literally. (Bug#9458)
7422 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7424 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7426 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7428 Fix minor problem found by static checking.
7429 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7430 initialized, to pacify gcc -Wuninitialized.
7432 * fileio.c: Report proper errno when syscall falls.
7433 (Finsert_file_contents): Save and restore errno,
7434 so that report_file_error outputs the correct diagnostic.
7435 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7437 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7439 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7441 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7443 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7444 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7446 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7448 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7449 about the current paragraph and restore it after the call to reseat.
7451 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7452 (bidi_find_paragraph_start): Search back for paragraph beginning
7453 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7454 (bidi_move_to_visually_next): Only trigger paragraph-related
7455 computations when the last character is a newline or at EOB, not
7456 just any NEUTRAL_B. (Bug#9470)
7458 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7459 truncated lines if point is covered by a display string. (Bug#9524)
7461 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7463 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7464 (cons_to_x_long): New function.
7465 (lisp_data_to_selection_data): Use it. Correct the test for
7466 short-versus-long data; it was negated. Break out of vector
7467 loop, for efficiency, when a long datum is discovered.
7469 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7471 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7473 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7475 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7476 GCC PR/17406) by declaring this function with external scope.
7478 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7480 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7481 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7483 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7485 * editfns.c (Fformat): Correctly handle text properties on "%%".

7495 of TAB characters in a composition.
7497 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7499 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7500 This occurs when processing a multibyte format.
7501 Problem reported by Wolfgang Jenker.
7503 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7505 * xdisp.c (try_cursor_movement): Only check for exact match if
7506 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7508 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7510 Remove unused external symbols.
7511 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7512 * xdisp.c (calc_pixel_width_or_height): Now static.
7513 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7514 * indent.c (check_display_width):
7515 * w32term.c: Fix comment to match code.
7516 * xterm.c, xterm.h (x_catching_errors): Remove.
7518 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7520 * xselect.c: Use signed conversions more consistently (Bug#9498).
7521 (selection_data_to_lisp_data): Assume incoming selection data are
7522 signed integers, not unsigned. This is to be consistent with
7523 outgoing selection data, which was modified to use signed integers
7524 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7525 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7526 expects long, not unsigned long.
7528 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7530 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7531 computation of loop end. Reported by Johan Bockgård
7534 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7536 * frame.c (Fother_visible_frames_p): Function deleted.
7538 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7540 * indent.c (compute_motion): Process display vector front to back
7541 rather than the other way around. (Bug#2496)
7543 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7545 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7547 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7549 * minibuf.c (Fread_from_minibuffer): Doc fix.
7551 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7553 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7554 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7556 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7558 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7559 value for non-existent files.
7561 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7563 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7564 set its "size" to -1. This will set the modtime_size field of
7565 the corresponding buffer to -1, which is what
7566 verify-visited-file-modtime expects for files that do not exist.
7569 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7571 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7573 * lisp.h: ... from here. push_key_description is no longer
7574 defined in keyboard.c, so its declaration should not be in
7575 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7576 logically belongs with push_key_description.
7578 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7580 * buffer.h: Include <sys/types.h> instead of <time.h>.
7581 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7582 Problem reported by Herbert J. Skuhra.
7584 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7586 * xml.c (parse_region): Make the parsing work for
7587 non-comment-starting XML files again (bug#9144).
7589 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7591 * image.c (gif_load): Fix calculation of bottom and right corner.
7594 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7596 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7597 redisplay in small windows.
7599 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7601 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7603 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7605 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7606 Operate on live windows only.
7608 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7610 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7612 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7614 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7615 only under bidi iteration.
7617 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7619 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7621 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7623 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7624 Without this fix, the command to link temacs failed due to an
7625 undefined symbol __builtin_isnan. This is because
7626 /usr/include/iso/math_c99.h #defines isnan(x) to
7627 __builtin_isnan(x), but the bundled gcc, which identifies itself
7628 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7630 * floatfns.c (isnan): #undef, and then #define to a clone of
7632 (Fisnan): Always define, since it's always available now.
7633 (syms_of_floatfns): Always define isnan at the Lisp level.
7635 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7637 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7639 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7641 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7642 The previous code assumed that file offsets (off_t values) fit in
7643 EMACS_INT variables, which is not true on typical 32-bit hosts.
7644 The code messed up by falsely reporting buffer overflow in cases
7645 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7646 when "big" contains more than 2**29 bytes, even though this
7647 inserts just one byte and does not overflow the buffer.
7648 (Finsert_file_contents): Store file offsets as off_t
7649 values, not as EMACS_INT values. Check for overflow when
7650 converting between EMACS_INT and off_t. When checking for
7651 buffer overflow or for overlap, take the offsets into account.
7652 Don't use EMACS_INT for small values where int suffices.
7653 When checking for overlap, fix a typo: ZV was used where
7654 ZV_BYTE was intended.
7655 (Fwrite_region): Don't assume off_t fits into 'long'.
7656 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7658 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7660 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7662 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7664 sprintf-related integer and memory overflow issues (Bug#9412).
7666 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7667 (esprintf, exprintf, evxprintf): New functions.
7668 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7669 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7670 (modify_event_symbol): Do not assume that the length of
7671 name_alist_or_stem is safe to alloca and fits in int.
7672 (Fexecute_extended_command): Likewise for function name and binding.
7673 (Frecursion_depth): Wrap around reliably on integer overflow.
7674 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7675 since some callers pass EMACS_INT values.
7676 (Fsingle_key_description): Don't crash if symbol name contains more
7677 than MAX_ALLOCA bytes.
7678 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7679 (get_minibuffer): Arg is now EMACS_INT, not int.
7680 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7681 (esprintf, exprintf, evxprintf): New decls.
7682 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7684 * dbusbind.c (signature_cat): New function.
7685 (xd_signature, Fdbus_register_signal):
7686 Do not overrun buffer; instead, report string overflow.
7688 * dispnew.c (add_window_display_history): Don't overrun buffer.
7689 Truncate instead; this is OK since it's just a log.
7691 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7692 even if the time zone offset is outlandishly large.
7693 Don't mishandle offset == INT_MIN.
7695 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7696 when creating daemon; the previous buffer-overflow check was incorrect.
7698 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7699 which has the guts of the old verror function.
7701 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7702 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7704 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7705 (font_unparse_xlfd): Don't blindly alloca long strings.
7706 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7707 fits in int, when using sprintf. Use single snprintf to count
7708 length of string rather than counting it via multiple sprintfs;
7709 that's simpler and more reliable.
7710 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7711 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7712 sprintf, in case result does not fit in int.
7714 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7715 (fontset_from_font): Print it.
7717 * frame.c (tty_frame_count): Now printmax_t, not int.
7718 (make_terminal_frame, set_term_frame_name): Print it.
7719 (x_report_frame_params): In X, window IDs are unsigned long,
7720 not signed long, so print them as unsigned.
7721 (validate_x_resource_name): Check for implausibly long names,
7722 and don't assume name length fits in 'int'.
7723 (x_get_resource_string): Don't blindly alloca invocation name;
7724 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7727 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7728 (xg_check_special_colors, xg_set_geometry):
7729 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7731 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7732 Use esprintf, not sprintf, in case result does not fit in int.
7734 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7735 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7736 it as a large positive number.
7737 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7738 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7740 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7741 in case result does not fit in int.
7743 * print.c (float_to_string): Detect width overflow more reliably.
7744 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7745 buffer overrun. Don't assume list length fits in 'int'. Treat
7746 print length of 0 as 0, not as infinity; to be consistent with other
7747 uses of print length in this function. Don't overflow print length
7748 index. Don't assume hash table size fits in 'long', or that
7749 vectorlike size fits in 'unsigned long'.
7751 * process.c (make_process): Use printmax_t, not int, to format
7752 process-name gensyms.
7754 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7756 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7757 to avoid potential buffer overrun.
7759 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7760 if X resource line is longer than 512 bytes.
7762 * xfns.c (x_window): Make sprintf buffer a bit bigger
7763 to avoid potential buffer overrun.
7765 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7769 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7771 Integer overflow fixes for scrolling, etc.
7772 Without these, Emacs silently mishandles large integers sometimes.
7773 For example, "C-u 4294967297 M-x recenter" was treated as if
7774 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7776 * xdisp.c (try_window_id): Check Emacs fixnum range before
7777 converting to 'int'.
7779 * window.c (window_scroll_line_based, Frecenter):
7780 Check that an Emacs fixnum is in range before assigning it to 'int'.
7781 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7782 values converted from Emacs fixnums.
7783 (Frecenter): Don't wrap around a line count if it is out of 'int'
7784 range; instead, treat it as an extreme value.
7785 (Fset_window_configuration, compare_window_configurations):
7786 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7788 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7789 that can exceed INT_MAX. Check that EMACS_INT value is in range
7790 before assigning it to the (possibly-narrower) index.
7791 (match_limit): Don't assume that a fixnum can fit in 'int'.
7793 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7796 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7797 (Fvertical_motion): Don't wrap around LINES values that don't fit
7798 in 'int'. Instead, treat them as extreme values. This is good
7799 enough for windows, which can't have more than INT_MAX lines anyway.
7801 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7803 * Require libxml/parser.h to avoid compilation warning.
7805 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7807 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7808 since this reportedly can destroy thread storage.
7810 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7812 * syntax.c (find_defun_start): Update all cache variables if
7813 exiting early (Bug#9401).
7815 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7817 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7819 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7820 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7821 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7823 * term.c (tty_append_glyph): New function.
7824 (produce_stretch_glyph): Static function and its prototype deleted.
7826 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7829 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7831 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7832 when checking :margin (Bug#9390).
7833 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7834 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7835 so that the name doesn't mislead. All uses changed.
7837 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7839 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7842 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7844 * xdisp.c (move_it_to): Don't bail out early when reaching
7845 position beyond to_charpos, if we are scanning backwards.
7846 (move_it_vertically_backward): When DY == 0, make sure we get to
7847 the first character in the line after the newline.
7849 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7851 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7852 (ccl_driver): Do not generate an out-of-range pointer.
7853 (Fccl_execute_on_string): Remove unnecessary check for
7854 integer overflow, noted by Stefan Monnier in
7855 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7856 Remove a FIXME that didn't need fixing.
7857 Simplify the newly-introduced buffer reallocation code.
7859 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7861 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7863 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7865 Integer and memory overflow issues (Bug#9196).
7867 * doc.c (get_doc_string): Rework so that
7868 get_doc_string_buffer_size is the actual buffer size, rather than
7869 being 1 less than the actual buffer size; this makes xpalloc more
7872 * image.c (x_allocate_bitmap_record, cache_image):
7873 * xselect.c (Fx_register_dnd_atom):
7874 Simplify previous changes by using xpalloc.
7876 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7877 since either will do and ptrdiff_t is convenient with xpalloc.
7879 * charset.c (charset_table_size)
7880 (struct charset_sort_data.priority): Now ptrdiff_t.
7881 (charset_compare): Don't overflow if priorities differ greatly.
7882 (Fsort_charsets): Don't assume list length fits in int.
7883 Check for size-calculation overflow when allocating sort data.
7884 (syms_of_charset): Allocate an initial charset table that is
7885 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7887 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7889 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7890 The actual value is always <= INT_MAX, and leaving it unsigned made
7891 overflow checking harder.
7893 * dispextern.h (struct glyph_matrix.rows_allocated)
7894 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7895 with xpalloc. The values are still always <= INT_MAX.
7897 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7899 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7900 (SAFE_NALLOCA): New macro.
7902 * region-cache.c (struct boundary.pos, find_cache_boundary)
7903 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7904 (set_cache_region, invalidate_region_cache)
7905 (revalidate_region_cache, know_region_cache, region_cache_forward)
7906 (region_cache_backward, pp_cache):
7907 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7908 so that ptrdiff_t * can be passed to xpalloc.
7909 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7910 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7911 (pp_cache): Don't assume cache_len fits in int.
7912 * region-cache.h: Adjust extern decls to match.
7914 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7915 EMACS_INT, since either will do, for xpalloc.
7917 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7918 (xnmalloc, xnrealloc, xpalloc): New functions.
7920 * bidi.c (bidi_shelve_header_size): New constant.
7921 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7922 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7924 * bidi.c (bidi_cache_shrink):
7925 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7927 Don't update size of array until after memory allocation succeeds,
7928 because xmalloc/xrealloc may not return.
7929 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7930 now that we have proper integer overflow checking.
7931 (record_overlay_string, overlay_strings): Catch overflows when
7932 calculating size of overlay_str_buf.
7934 * callproc.c (Fcall_process): Check for size overflow when
7935 calculating size of args2.
7936 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7937 Normally we prefer signed values, but sticking with ptrdiff_t would
7938 require adding more-complicated checks.
7940 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7941 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7942 Redo buffer-overflow calculations to avoid integer overflow.
7943 Add a FIXME comment where memory seems to be over-allocated.
7945 * character.c (Fstring): Check for size-calculation overflow.
7947 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7948 unnecessary integer overflow. Check for size overflow.
7949 (encode_coding_object): Don't update size until xmalloc succeeds.
7951 * composite.c (get_composition_id): Check for overflow in glyph
7952 length calculations.
7954 Integer and memory overflow fixes for display code.
7955 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7956 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7957 (scrolling_window): Check for overflow in size calculations.
7958 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7970 (get_doc_string): Check for size calculation overflow.
7971 Don't update size until allocation succeeds.
7972 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7973 EMACS_INT, where ptrdiff_t will do.
7974 (Fsubstitute_command_keys): Check for string overflow.
7976 * editfns.c (set_time_zone_rule): Don't assume environment length
7978 (message_length): Now ptrdiff_t, not int.
7979 (Fmessage_box): Don't update size until allocation succeeds.
7980 Don't assume message length fits in int.
7981 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7983 * emacs.c (main): Do not reallocate argv, since there is a null at
7984 the end that can be overwritten, and this way there's no need to
7985 worry about size-calculation overflow.
7986 (sort_args): Check for size-calculation overflow.
7988 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7990 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7992 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7993 (x_set_scroll_bar_width, x_figure_window_size):
7994 Check for integer overflow.
7995 (x_set_alpha): Do not assume XINT fits in int.
7997 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7998 This is for the members text_lines, text_cols, total_lines, total_cols,
7999 where the system imposes an 'int' limit.
8001 * fringe.c (Fdefine_fringe_bitmap):
8002 Don't update size until alloc works.
8004 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8005 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8007 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8008 Check for size-calculation overflow.
8009 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8010 do, as we prefer signed integers.
8011 (id_to_widget.max_size, id_to_widget.used)
8012 (xg_store_widget_in_map, xg_remove_widget_from_map)
8013 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8014 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8015 Use and return ptrdiff_t, not int.
8016 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8017 * gtkutil.h: Change prototypes to match the above.
8019 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8020 are duplicate now that they've been promoted to lisp.h.
8021 (x_allocate_bitmap_record, x_alloc_image_color)
8022 (make_image_cache, cache_image, xpm_load):
8023 Don't update size until alloc is done.

8026 Check for size calculation overflow.
8027 (ct_colors_allocated_max): New constant.

8033 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8034 Use ptrdiff_t, not int, to count maps.
8035 (read_char_minibuf_menu_prompt): Check for overflow in size
8036 calculations. Don't update size until allocation succeeds.

8048 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8050 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8051 Now ptrdiff_t, not int.
8052 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

8064 (Fset_match_data): Don't assume list lengths fit in 'int'.
8066 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8067 for command line length. Do not attempt to address one before the

8071 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8073 (encode_terminal_code, calculate_costs): Check for size
8074 calculation overflow.

8077 done. Redo calculations to avoid overflow.
8078 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8080 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

8097 (Finternal_make_lisp_face, cache_face):
8098 Check for size calculation overflow.
8099 (cache_face): Treat size calculation overflows as if they were
8100 memory exhaustion (the usual treatment), rather than aborting.
8102 * xfns.c (x_encode_text, x_set_name_internal)
8103 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8104 sizes, since they can exceed INT_MAX in size. Check for size
8105 calculation overflow.
8107 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8108 (xg_select): Check for size calculation overflow.
8109 Don't update size until alloc done.
8111 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8112 as sprintf is limited to int lengths.
8114 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8115 (X_LONG_MIN): New macros.
8116 Use them to make the following changes clearer.
8117 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8118 This change doesn't affect the value now, but it may help remind
8119 future maintainers not to raise the value too much later.
8120 (SELECTION_QUANTUM): Remove, replacing with ...
8121 (selection_quantum): ... new function, which avoids overflow.
8123 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8124 assumption that selection length fits in 'int'.
8125 (x_reply_selection_request, x_handle_selection_request)
8126 (x_get_window_property, receive_incremental_selection)
8127 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8128 (lisp_data_to_selection_data, clean_local_selection_data):

8132 Redo calculations to avoid overflow.
8133 (x_reply_selection_request): When sending hint, ceiling it at
8134 X_LONG_MAX rather than relying on wraparound overflow to send

8137 (lisp_data_to_selection_data, x_property_data_to_lisp):
8138 Check for size-calculation overflow.
8139 (x_get_window_property, receive_incremental_selection)

8141 Don't store size until memory allocation succeeds.
8142 (x_get_window_property): Plug memory leak on memory exhaustion.
8143 Don't double-block input; malloc is safe here. Don't assume 2**34
8144 - 4 fits in unsigned long. Add an xassert to check
8145 XGetWindowProperty overflow. Be more careful about overflow
8146 calculations, and distinguish size from memory overflow better.
8147 (receive_incremental_selection): When tracing, don't assume
8148 unsigned int is less than INT_MAX.
8149 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8150 harmful) conversions of unsigned short to int.
8151 (lisp_data_to_selection_data): Don't assume that integers
8152 in the range -65535 through -1 fit in an X unsigned short.
8153 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8154 result parameters unless successful. Rely on cons_to_unsigned
8155 to report problems with elements; the old code wasn't right anyway.
8156 (x_check_property_data): Check for int overflow; we cannot use
8157 a wider type due to X limits.
8158 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8189 * image.c (xpm_get_color_table_h):
8190 * lisp.h (hash_lookup, hash_put):
8191 * minibuf.c (Ftest_completion):
8192 Use ptrdiff_t for hash table indexes, not int (which is too
8193 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8194 32-bit --with-wide-int hosts).
8196 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8197 Add a FIXME comment about memory leaks.
8198 (syms_of_charset): Don't assume xmalloc returns.
8200 Don't assume that stated character widths fit in int.
8201 * character.c (Fchar_width, c_string_width, lisp_string_width):
8202 * character.h (CHAR_WIDTH):
8203 * indent.c (MULTIBYTE_BYTES_WIDTH):
8204 Use sanitize_char_width to avoid undefined and/or bad behavior
8205 with outlandish widths.
8206 * character.h (sanitize_tab_width): Rename from sanitize_width,
8207 now that we have two such functions. All uses changed.
8208 (sanitize_char_width): New inline function.
8210 Don't assume that tab-width fits in int.
8211 * character.h (sanitize_width): New inline function.
8212 (SANE_TAB_WIDTH): New macro.

8218 * fileio.c: Integer overflow issues with file modes.
8219 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.

8226 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8227 (x_send_scroll_bar_event): Likewise. Check that the size does not
8228 exceed limits imposed by XClientMessageEvent, as well as the usual
8229 ptrdiff_t and size_t limits.
8231 * keyboard.c: Overflow, signedness and related fixes.
8232 (make_lispy_movement): Use same integer type in forward decl
8233 that is used in the definition.
8234 (read_key_sequence, keyremap_step):
8235 Change bufsize argument back to int, undoing my 2011-03-30 change.
8236 We prefer signed types, and int is wide enough here.
8237 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8238 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8239 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8240 length, not size_t. Use ptrdiff_t for index, not int.
8241 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8242 possibility of integer overflow.
8244 Overflow, signedness and related fixes for images.

8265 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8266 (lookup_image): Remove unnecessary tests.
8267 (xbm_image_p): Locals are now of int, not EMACS_INT,
8268 since parse_image_check makes sure they fit into int.
8269 (png_load, gif_load, svg_load_image):
8270 Prefer int to unsigned where either will do.
8271 (tiff_handler): New function, combining the cores of the
8272 old tiff_error_handler and tiff_warning_handler.
8273 This function is rewritten to use vsnprintf and thereby avoid
8274 stack buffer overflows. It uses only the features of vsnprintf
8275 that are common to both POSIX and native Microsoft.
8276 (tiff_error_handler, tiff_warning_handler): Use it.
8277 (tiff_load, gif_load, imagemagick_load_image):
8278 Don't assume :index value fits in 'int'.
8279 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8280 (imagemagick_load_image): Check that crop parameters fit into
8281 the integer types that MagickCropImage accepts. Don't assume
8282 Vimagemagick_render_type has a nonnegative value. Don't assume
8283 size_t fits in 'long'.
8284 (gs_load): Use printmax_t to print the widest integers possible.
8285 Check for integer overflow when computing image height and width.

8294 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8295 the display spec is of the form `(space ...)'.
8296 (handle_display_spec): Return the value returned by
8297 handle_single_display_spec, not just 1 or zero.
8298 (handle_single_display_spec): If the display spec is of the form
8299 `(space ...)', and specifies display in the text area, return 2
8301 (try_cursor_movement): Check for the need to scroll more
8302 accurately, and prefer exact match for point under bidi.
8303 Don't advance `row' beyond the last row of the window.
8305 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8306 into disp_prop; all users changed.
8308 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8309 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8310 for the text covered by the display property.
8312 2011-08-25 Chong Yidong <cyd@stupidchicken.com>

8321 buffers, return left-to-right.
8322 (set_cursor_from_row): Consider candidate row a win if its glyph
8323 represents a newline and point is on that newline. Fixes cursor
8324 positioning on the newline at EOL of R2L text within L2R
8325 paragraph, and vice versa.
8326 (try_cursor_movement): Check continued rows, in addition to
8327 continuation rows. Fixes unwarranted scroll when point enters a
8328 continued line of R2L text within an L2R paragraph, or vice versa.
8329 (cursor_row_p): Consider the case of point being equal to
8330 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8331 from the end of a short line to the beginning of a continued line
8332 of R2L text within L2R paragraph.
8333 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8334 composed characters.
8336 * bidi.c (bidi_check_type): Use xassert.
8337 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p

8349 2011-08-22 Kenichi Handa <handa@m17n.org>
8351 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8352 extra slot even if the purpose is char-code-property-table.
8354 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8356 * xdisp.c (redisplay_window): When computing centering_position,
8357 account for the height of the header line. (Bug#8874)
8359 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8360 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8361 candidate is selected by the mouse, and that candidate has a
8362 composed character under the mouse.
8364 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8365 coordinates reported by pos-visible-in-window-p for a composed
8366 character in column zero.

8372 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8374 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8375 consider it a hit if to_charpos is anywhere in the range of the
8376 composed buffer positions.
8378 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8380 * image.c (gif_load): Don't assume that each subimage has the same
8381 dimensions as the base image. Handle disposal method that is
8382 "undefined" by the gif spec (Bug#9335).
8384 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8386 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8389 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8391 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8392 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8393 from an Org mode buffer to a Speedbar frame.
8395 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8396 a composition, take its buffer position from IT->cmp_it.charpos.
8397 Fixes cursor positioning at the beginning of a line that begins
8398 with a composed character.
8400 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8402 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8403 character bidirectional type, use STRONG_L instead. Fixes crashes
8404 in a buffer produced by `describe-categories'.
8406 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8407 members before the level stack, so they would be saved and
8408 restored when copying iterator state. Fixes incorrect reordering
8409 around TABs covered by display properties.
8411 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8485 ppos_it. Fixes vertical cursor motion when line beginning is
8486 covered by an image. (Bug#9296)
8488 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8490 * nsterm.h (ns_run_ascript): Declare.

8493 * nsfns.m (as_script, as_result, as_status): New static variables.
8494 (ns_run_ascript): New function.
8495 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8496 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8497 the event loop. Get status from as_status (Bug#7276).
8499 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8500 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8501 the event loop (Bug#7276).

8527 (Fnetwork_interface_list): Allocate in increments of bytes instead
8528 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8529 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8531 (struct ifflag_def): notrailers is smart on OSX.
8532 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8533 Get hardware address with getifaddrs if available.
8535 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8537 * xdisp.c (iterate_out_of_display_property): xassert that
8538 IT->position is set to within IT->object's boundaries. Break from
8539 the loop as soon as EOB is reached; avoids infloops in redisplay
8540 when IT->position is set up wrongly due to some bug.
8541 Set IT->current to match the bidi iterator unconditionally.
8542 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8543 entry. Force push_it to save on the stack the current
8544 buffer/string position, to be restored by pop_it. Fix flags in
8545 the iterator structure wrt the object coming from a display
8546 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8547 properties. (Bug#9284)
8549 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8551 * fontset.c (fontset_get_font_group): Add proper type checks.

8561 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8563 * xdisp.c (forward_to_next_line_start): Allow to use the
8564 no-display-properties-and-no-overlays under bidi display.
8565 Set disp_pos in the bidi iterator to avoid searches for display
8566 properties and overlays.
8568 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8570 * editfns.c (Fset_time_zone_rule): Document relationship with the

8576 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8578 * composite.c (autocmp_chars): Don't reset point. That is done by
8579 restore_point_unwind (Bug#5984).
8581 2011-08-07 Juri Linkov <juri@jurta.org>
8583 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8584 to show the arg `TIME' instead of `TIMEVAL'.
8586 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8588 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8589 display property strides EOL and includes a newline, as in
8590 longlines-mode. (Bug#9254)
8591 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8592 word-wrap under bidirectional display. (Bug#9224)
8594 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8595 is non-zero, even if the data buffer is NULL. Fixes a crash in
8596 vertical-motion with longlines-mode. (Bug#9254)
8598 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8600 * bidi.c <bidi_cache_total_alloc>: Now static.
8601 (bidi_initialize): Initialize bidi_cache_total_alloc.
8603 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8606 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8607 amount allocated this far in `bidi_cache_total_alloc'.
8608 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8609 non-zero, only free the data buffer without restoring the cache
8610 contents. All callers changed.
8612 * dispextern.h (bidi_unshelve_cache): Update prototype.
8614 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8615 (move_it_in_display_line, move_it_to)
8616 (move_it_vertically_backward, move_it_by_lines): Replace the call
8617 to xfree to an equivalent call to bidi_unshelve_cache.
8618 (move_it_in_display_line_to): Fix logic of returning
8619 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8621 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8623 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8624 came from a string character with a `cursor' property. (Bug#9229)

8656 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8657 so that it is not optimized away.
8659 * xdisp.c (compute_display_string_pos): Remove unused local.
8661 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8663 Fix slow cursor motion and scrolling in large buffers with
8664 selective display, like Org Mode buffers. (Bug#9218)
8666 * dispextern.h (struct bidi_it): New member disp_prop_p.
8668 * xdisp.c: Remove one-slot cache of display string positions.
8669 (compute_display_string_pos): Accept an additional argument
8670 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8671 for a display string or property. If found, set DISP_PROP_P
8674 * bidi.c (bidi_fetch_char): Accept an additional argument
8675 DISP_PROP_P, and pass it to compute_display_string_pos.
8676 Only handle text covered by a display string if DISP_PROP_P is returned
8677 non-zero. All callers of bidi_fetch_char changed.
8679 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8681 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8683 2010-12-03 Don March <don@ohspite.net>
8685 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8686 last character M-[char] is translated to ESC [char] (bug#7541).
8688 2011-08-02 Kenichi Handa <handa@m17n.org>
8690 * lisp.h (uniprop_table): Extern it.
8692 * chartab.c (uniprop_table): Make it non-static.
8694 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8696 * xdisp.c (forward_to_next_line_start): Accept additional argument
8697 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8699 (reseat_at_next_visible_line_start): Use the bidi iterator state
8700 returned by forward_to_next_line_start to restore the state of
8701 it->bidi_it after backing up to previous newline. (Bug#9212)
8703 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8705 * regex.c (re_comp): Protoize.
8706 (re_exec): Fix return type.
8707 (regexec): Fix type of `ret'. (Bug#9203)
8709 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8711 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8712 This is needed if max-image-size is a floating-point number.
8714 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8716 * print.c (print_object): Print empty symbol as ##.
8718 * lread.c (read1): Read ## as empty symbol.
8720 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8722 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8723 setting frame foreground color (Bug#9175).
8724 (x_set_background_color): Likewise.
8726 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8727 contents (Bug#9176).
8728 (EmacsTooltip -init): Remove bezels and add shadows to
8731 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8732 or scroll bar (Bug#8470).
8734 * nsfont.m (nsfont_open): Remove assignment to voffset and
8735 unnecessary vars hshink, expand, hd, full_height, min_height.
8736 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8738 * nsterm.h (nsfont_info): Remove voffset field.
8740 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8742 Implement strike-through and overline on NextStep (Bug#8863).
8744 * nsfont.m (nsfont_open): Use underline position provided by font,
8745 instead of hard-coded value of 2.
8746 (nsfont_draw): Call ns_draw_text_decoration instead.
8748 * nsterm.h: Add declaration for ns_draw_text_decoration.
8750 * nsterm.m (ns_draw_text_decoration): New function for drawing
8751 underline, overline, and strike-through.
8752 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8753 ns_draw_text_decoration. Change treatment of cursor drawing to
8754 accommodate underlining, etc.
8756 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8758 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8761 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8763 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8764 Without this fix, if a signal arrives just after memory fills up,
8765 'malloc' might be invoked reentrantly.
8767 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8768 In other words, assume that every image size is allowed, on non-X
8769 hosts. This assumption is probably wrong, but it lets Emacs compile.
8771 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8773 * regex.c (re_iswctype): Convert return values to boolean.
8775 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8777 * xdisp.c (compute_display_string_pos): Don't use cached display
8778 string position if the buffer had its restriction changed.
8781 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8783 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8785 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8787 Integer signedness and overflow and related fixes. (Bug#9079)
8789 * bidi.c: Integer size and overflow fixes.
8790 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8791 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8792 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8793 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8794 (bidi_find_other_level_edge):
8795 Use ptrdiff_t instead of EMACS_INT where either will do.
8796 This works better on 32-bit hosts configured --with-wide-int.
8797 (bidi_cache_ensure_space): Check for size-calculation overflow.
8798 Use % rather than repeated addition, for better worst-case speed.
8799 Don't set bidi_cache_size until after xrealloc returns, because it
8801 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8802 (bidi_cache_ensure_space): Also check that the bidi cache size
8803 does not exceed that of the largest Lisp string or buffer. See Eli
8804 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8806 * alloc.c (__malloc_size_t): Remove.
8807 All uses replaced by size_t. See Andreas Schwab's note
8808 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8810 * image.c: Improve checking for integer overflow.
8811 (check_image_size): Assume that f is nonnull, since
8812 it is always nonnull in practice. This is one less thing to
8813 worry about when checking for integer overflow later.
8814 (x_check_image_size): New function, which checks for integer
8815 overflow issues inside X.
8816 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8817 This removes the need for a memory_full check.
8818 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8819 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8820 (xbm_read_bitmap_data): Change locals back to 'int', since
8821 their values must fit in 'int'.
8822 (xpm_load_image, png_load, tiff_load):
8823 Invoke x_create_x_image_and_pixmap earlier,
8824 to avoid much needless work if the image is too large.
8825 (tiff_load): Treat overly large images as if
8826 x_create_x_image_and_pixmap failed, not as malloc failures.
8827 (gs_load): Use x_check_image_size.
8829 * gtkutil.c: Omit integer casts.
8830 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8831 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8833 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8835 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8836 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8837 would wrongly return t on a 64-bit host.
8839 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8840 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8841 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8842 and therefore cause GCC to emit a bogus diagnostic in some cases.
8844 * image.c: Integer signedness and overflow and related fixes.
8845 This is not an exhaustive set of fixes, but it's time to
8846 record what I've got.
8847 (lookup_pixel_color, check_image_size): Remove redundant decls.
8848 (check_image_size): Don't assume that arbitrary EMACS_INT values
8849 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8850 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8851 (tiff_load, imagemagick_load_image):
8852 Check for overflow in size calculations.
8853 (x_create_x_image_and_pixmap): Remove unnecessary test for
8854 xmalloc returning NULL; that can't happen.
8855 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8856 (xpm_color_bucket): Use better integer hashing function.
8857 (xpm_cache_color): Don't possibly over-allocate memory.
8858 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8859 (gif_memory_source):
8860 Use ptrdiff_t, not int or size_t, to record sizes.
8861 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8862 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8863 either works, as we prefer signed integers.
8864 (tiff_read_from_memory, tiff_write_from_memory):
8865 Return tsize_t, not size_t, since that's what the TIFF API wants.
8866 (tiff_read_from_memory): Don't fail simply because the read would
8867 go past EOF; instead, return a short read.
8868 (tiff_load): Omit no-longer-needed casts.
8869 (Fimagemagick_types): Don't assume size fits into 'int'.
8871 Improve hashing quality when configured --with-wide-int.
8872 * fns.c (hash_string): New function, taken from sxhash_string.
8873 Do not discard information about ASCII character case; this
8874 discarding is no longer needed.
8875 (sxhash-string): Use it. Change sig to match it. Caller changed.
8876 * lisp.h: Declare it.
8877 * lread.c (hash_string): Remove, since we now use fns.c's version.
8878 The fns.c version returns a wider integer if --with-wide-int is
8879 specified, so this should help the quality of the hashing a bit.
8881 * emacs.c: Integer overflow minor fix.
8882 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8883 Define only if GNU_LINUX.
8884 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8886 * dispnew.c: Integer signedness and overflow fixes.
8887 Remove unnecessary forward decls, that were a maintenance hassle.
8888 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8890 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8891 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8892 (prepare_desired_row, line_draw_cost):
8893 Use int, not unsigned, where either works.
8894 (save_current_matrix, restore_current_matrix):
8895 Use ptrdiff_t, not size_t, where either works.
8896 (init_display): Check for overflow more accurately, and without
8897 relying on undefined behavior.
8899 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8900 Remove, replacing with the new symbols in lisp.h. All uses changed.
8901 * fileio.c (make_temp_name):
8902 * filelock.c (lock_file_1, lock_file):
8903 * xdisp.c (message_dolog):
8904 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8905 Use pMd etc. instead.
8906 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8907 replacing the pWIDE etc. symbols removed from editfns.c.
8909 * keyboard.h (num_input_events): Now uintmax_t.
8910 This is (very slightly) less likely to mess up due to wraparound.
8913 * buffer.c: Integer signedness fixes.
8914 (alloc_buffer_text, enlarge_buffer_text):
8915 Use ptrdiff_t rather than size_t when either will do, as we prefer
8918 * alloc.c: Integer signedness and overflow fixes.
8919 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8920 (__malloc_size_t): Default to size_t, not to int.
8921 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8922 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8923 Prefer ptrdiff_t to size_t when either would do, as we prefer
8925 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8926 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8927 Now const. Initialize with values that are in range even if char
8929 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8930 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8931 These functions do the right thing with sizes > 2**32.
8932 (check_depth): Now ptrdiff_t, not int.
8933 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8934 Adjust to new way of storing sizes. Check for size overflow bugs
8936 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8937 slightly wrong anyway, as it missed one instance of
8938 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8939 (refill_memory_reserve): Omit needless cast to size_t.
8940 (mark_object_loop_halt): Mark as externally visible.
8942 * xselect.c: Integer signedness and overflow fixes.
8943 (Fx_register_dnd_atom, x_handle_dnd_message):
8944 Use ptrdiff_t, not size_t, since we prefer signed.
8945 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8946 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8947 x_dnd_atoms_size and x_dnd_atoms_length.
8949 * doprnt.c: Prefer signed to unsigned when either works.
8951 * doprnt.c (doprnt):
8953 * xdisp.c (vmessage):
8954 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8955 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8956 prefer signed arithmetic to avoid comparison confusion.
8957 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8958 but is a bit tricky.
8960 Assume freestanding C89 headers, string.h, stdlib.h.
8961 * data.c, doprnt.c, floatfns.c, print.c:
8962 Include float.h unconditionally.
8963 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8964 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8965 * regex.c: Likewise for stddef.h, string.h.
8966 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8967 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8968 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8969 (STDC_HEADERS): Remove obsolete defines.
8970 * sysdep.c: Include limits.h unconditionally.
8972 Assume support for memcmp, memcpy, memmove, memset.
8973 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8974 * regex.c (memcmp, memcpy):
8975 Remove; we assume C89 now.
8977 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8978 (__malloc_safe_bcopy): Remove; no longer needed.
8980 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8981 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8982 well either way, and we prefer signed to unsigned.
8984 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8986 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8987 closes the connection while we're reading (bug#9182).
8989 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8991 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8992 are specified (Bug#9168).
8994 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8996 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8997 Found by GCC static checking and --with-wide-int on a 32-bit host.
8999 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9001 * xdisp.c (compute_display_string_pos): Fix logic of caching
9002 previous display string position. Initialize cached_prev_pos to
9003 -1. Fixes slow-down at the beginning of a buffer.
9005 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9007 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9008 for attrs[LFACE_FONTSET_INDEX].
9010 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9012 * xml.c (parse_region): Remove unused local
9013 that was recently introduced.
9015 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9017 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9018 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9020 * xdisp.c (move_it_in_display_line_to): Record the best matching
9021 position for TO_CHARPOS while scanning the line, and restore it on
9022 exit if none of the characters scanned was an exact match.
9023 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9024 when exact match is impossible due to invisible text, and the
9025 lines are truncated.
9027 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9029 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9032 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9034 Fix a significant slow-down of cursor motion with C-n, C-p,
9035 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9036 auto-repeat under bidi redisplay in fontified buffers.
9037 * xdisp.c (compute_stop_pos_backwards): New function.
9038 (next_element_from_buffer): Call compute_stop_pos_backwards to
9039 find a suitable prev_stop when we find ourselves before
9041 (reseat): Don't look for prev_stop, as that could mean a very long
9043 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9044 <cached_disp_overlay_modiff>: Cache for last found display string
9046 (compute_display_string_pos): Return the cached position if asked
9047 about the same buffer in the same area of character positions, and
9048 the buffer wasn't changed since the time the display string
9049 position was cached.
9051 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9053 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9054 is an integer, which is important for empty lines. (Bug#9149)
9056 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9058 * frame.c (Fmodify_frame_parameters): In tty case, update the
9059 default face if necessary (Bug#4238).
9061 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9063 * editfns.c (Fstring_to_char): No need to explain what a character
9064 is in the docstring (Bug#6576).
9066 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9068 * xml.c (parse_region): Make sure we always return a tree.
9070 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9072 * xml.c (parse_region): If a document contains only comments,
9075 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9077 * xml.c (make_dom): Return comments, too.
9079 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9082 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9083 and the surrounding thread.
9084 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9085 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9086 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9088 * s/openbsd.h (BROKEN_SIGIO): Define.
9089 * unexelf.c (unexec) [__OpenBSD__]:
9090 Don't update the .mdebug section of the Alpha COFF symbol table.
9092 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9094 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9097 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9099 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9100 This fixes some race conditions on the permissions of any newly
9103 * alloc.c (valid_pointer_p): Use pipe, not open.
9104 This fixes some permissions issues when debugging.
9106 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9107 If fchown fails to set both uid and gid, try to set just gid,
9108 as that is sometimes allowed. Adjust the file's mode to eliminate
9109 setuid or setgid bits that are inappropriate if fchown fails.
9111 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9113 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9114 to compare Lisp_Objects.
9115 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9116 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9117 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9119 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>

9129 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9130 This works around a problem with the previous change to Fcopy_file.
9131 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9132 and without this change, GCC might complain about discarding
9133 fchown's return value.
9135 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9137 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

9181 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9182 "cannot optimize loop, the loop counter may overflow", a symptom
9184 * indent.c (Fvertical_motion): Mark locals as initialized.
9185 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9187 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

9231 the iterator is before prev_stop.
9232 (init_iterator): Initialize bidi_p from the default value of

9750 Random fixes. E.g., (random) never returned negative values.
9751 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9752 subseconds part to the entropy, as that's a bit more random.
9753 Prefer signed to unsigned, since the signedness doesn't matter and
9754 in general we prefer signed. When given a limit, use a
9755 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9756 latter isn't right if USE_2_TAGS_FOR_INTS.
9757 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9758 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9771 This is more efficient than Ffile_directory_p and avoids a minor race.
9773 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9775 * buffer.c (Foverlay_put): Say what the return value is
9778 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9781 (barf_or_query_if_file_exists): Make the "File is a directory"
9782 error be more correct.
9784 * fns.c (Frequire): Remove the mention of the .gz files, since
9785 that's installation-specific, but keep the mention of
9786 `get-load-suffixes'.
9788 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9790 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9903 * eval.c (struct backtrace): Simplify and port the data structure.
9904 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9905 signed bit field, as this assumption is not portable and it makes
9906 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9907 "char debug_on_exit : 1" as this is not portable either; instead,
9908 use the portable "unsigned int debug_on_exit : 1". Remove unused

10071 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
10073 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10075 Integer and buffer overflow fixes (Bug#8873).
10077 * print.c (printchar, strout): Check for string overflow.
10078 (PRINTPREPARE, printchar, strout):
10079 Don't set size unless allocation succeeds.
10081 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10082 for sizes. Check for string overflow more accurately.
10083 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10085 * macros.c: Integer and buffer overflow fixes.
10086 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10087 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10088 Use ptrdiff_t, not int, for sizes.
10089 Don't increment bufsize until after realloc succeeds.
10090 Check for size-calculation overflow.
10091 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10093 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10095 * lread.c: Integer overflow fixes.
10096 (read_integer): Radix is now EMACS_INT, not int,
10097 to improve quality of diagnostics for out-of-range radices.
10098 Calculate buffer size correctly for out-of-range radices.
10099 (read1): Check for integer overflow in radices, and in
10100 read-circle numbers.
10101 (read_escape): Avoid int overflow.
10102 (Fload, openp, read_buffer_size, read1)
10103 (substitute_object_recurse, read_vector, read_list, map_obarray):
10104 Use ptrdiff_t, not int, for sizes.
10105 (read1): Use EMACS_INT, not int, for sizes.
10106 Check for size overflow.
10108 * image.c (cache_image): Check for size arithmetic overflow.
10110 * lread.c: Integer overflow issues.
10111 (saved_doc_string_size, saved_doc_string_length)
10112 (prev_saved_doc_string_size, prev_saved_doc_string_length):
10113 Now ptrdiff_t, not int.
10114 (read1): Don't assume doc string length fits in int. Check for
10115 out-of-range doc string lengths.
10116 (read_list): Don't assume file position fits in int.
10117 (read_escape): Check for hex character overflow.
10119 2011-06-22 Leo Liu <sdl.web@gmail.com>
10121 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10122 Move to minibuffer.el.
10124 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10126 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10127 The following patches are for when GLYPH_DEBUG && !XASSERT.
10128 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10129 * dispnew.c (flush_stdout):
10130 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10131 Mark as externally visible.
10132 * dispnew.c (check_window_matrix_pointers): Now static.
10133 * dispnew.c (window_to_frame_vpos):
10134 * xfns.c (unwind_create_frame):
10135 * xterm.c (x_check_font): Remove unused local.
10136 * scroll.c (CHECK_BOUNDS):
10137 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10138 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10139 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10140 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10141 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10143 (debug_method_add): Use va_list and vsprintf rather than relying
10144 on undefined behavior with wrong number of arguments.
10145 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10146 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10147 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10148 since we're not interested in debugging glyphs with old libraries.
10149 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10150 GCC 4.6.0's static checking.
10152 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10154 Integer overflow and signedness fixes (Bug#8873).

10162 (x_create_bitmap_from_data, x_create_bitmap_from_file)
10163 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10164 (x_create_bitmap_from_xpm_data):
10165 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10166 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10168 * xfaces.c (load_pixmap):
10169 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10170 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10171 (.bitmaps_last, struct x_output.icon_bitmap):
10172 Use ptrdiff_t, not int, for bitmap indexes.
10173 (x_allocate_bitmap_record): Check for size overflow.
10174 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10176 Use ptrdiff_t, not int, for overlay counts.
10177 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10178 * editfns.c (overlays_around, get_pos_property):
10179 * textprop.c (get_char_property_and_overlay):
10180 * xdisp.c (next_overlay_change, note_mouse_highlight):
10181 * xfaces.c (face_at_buffer_position):
10182 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10183 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10184 (Fnext_overlay_change, Fprevious_overlay_change)
10185 (mouse_face_overlay_overlaps, Foverlays_in):
10186 Use ptrdiff_t, not int, for sizes.
10187 (overlays_at, overlays_in): Check for size-calculation overflow.
10189 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10191 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10192 (x_session_initialize): Do not assume string length fits in int.
10194 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10195 This is unlikely, but can occur if DPI is outlandish.
10197 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10198 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10200 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10201 * xrdb.c (magic_file_p, search_magic_path):
10202 Omit last arg SUFFIX; it was always 0. All callers changed.
10203 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10205 * xfont.c (xfont_match): Avoid need for strlen.
10207 * xfns.c: Don't assume strlen fits in int.
10208 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10210 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10211 not unsigned long, as we prefer signed integers. All callers changed.
10212 Detect integer overflow in repeat count.
10213 (message_dolog): Don't assume print length fits in 39 bytes.
10214 (display_mode_element): Don't assume strlen fits in int.
10216 * termcap.c: Don't assume sizes fit in int and never overflow.
10217 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10218 (gobble_line): Check for size-calculation overflow.
10220 * minibuf.c (Fread_buffer):
10221 * lread.c (intern, intern_c_string):
10222 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10223 Don't assume string length fits in int.
10225 * keyboard.c (parse_tool_bar_item):
10226 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10228 * font.c: Don't assume string length fits in int.
10229 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10230 Use ptrdiff_t, not int.
10231 (font_intern_prop): Don't assume string length fits in int.
10232 Don't assume integer property fits in fixnum.
10233 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10235 * filelock.c: Fix some buffer overrun and integer overflow issues.
10236 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10237 Reformulate so as not to need the command string.
10238 Invoke gzip -cd rather than gunzip, as it's more portable.
10239 (lock_info_type, lock_file_1, lock_file):
10240 Don't assume pid_t and time_t fit in unsigned long.
10241 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10242 (current_lock_owner): Prefer signed type for sizes.
10243 Use memcpy, not strncpy, where memcpy is what is really wanted.
10244 Don't assume (via atoi) that time_t and pid_t fit in int.
10245 Check for time_t and/or pid_t out of range, e.g., via a network share.
10246 Don't alloca where an auto var works fine.
10248 * fileio.c: Fix some integer overflow issues.
10249 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10250 Don't assume string length fits in int.
10251 (directory_file_name): Don't assume string length fits in long.
10252 (make_temp_name): Don't assume pid fits in int, or that its print
10253 length is less than 20.
10255 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10257 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10259 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10261 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10262 We prefer signed integers, even for size calculations.
10264 * emacs.c: Don't assume string length fits in 'int'.
10265 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10266 (main): Don't invoke strlen when not needed.
10268 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10269 (XD_DEBUG_MESSAGE): Don't waste a byte.
10271 * callproc.c (getenv_internal_1, getenv_internal)
10272 (Fgetenv_internal):
10273 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10275 * lread.c (invalid_syntax): Omit length argument.
10276 All uses changed. This doesn't fix a bug, but it simplifies the
10277 code away from its former Hollerith-constant appearance, and it's
10278 one less 'int' to worry about when looking at integer-overflow issues.
10279 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10281 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10282 This didn't break anything, but it didn't help either.
10283 It's confusing to put a bogus integer in a place where the actual
10284 value does not matter.
10285 (LIST_END_P): Remove unused macro and its bogus comment.
10286 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10288 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10289 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10291 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10292 We prefer signed types, and the value cannot exceed the EMACS_INT
10293 range anyway (because otherwise the length would not be representable).
10294 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10295 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10296 This avoids a GCC warning when WIDE_EMACS_INT.
10298 * indent.c (sane_tab_width): New function.
10299 (current_column, scan_for_column, Findent_to, position_indentation)
10300 (compute_motion): Use it. This is just for clarity.
10301 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10303 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10305 * lisp.h (lint_assume): New macro.
10306 * composite.c (composition_gstring_put_cache):
10307 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10309 * editfns.c, insdel.c:
10310 Omit unnecessary forward decls, to simplify future changes.
10312 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10314 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10316 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10317 Use much-faster test for byte-length change.
10318 Don't assume string byte-length fits in 'int'.
10319 Check that character arg fits in 'int'.
10320 (mapcar1): Declare byte as byte, for clarity.
10322 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10324 * fns.c (concat): Catch string overflow earlier.
10325 Do not rely on integer wraparound.
10327 * dispextern.h (struct it.overlay_strings_charpos)
10328 (struct it.selective): Now EMACS_INT, not int.
10329 * xdisp.c (forward_to_next_line_start)
10330 (back_to_previous_visible_line_start)
10331 (reseat_at_next_visible_line_start, next_element_from_buffer):
10332 Don't arbitrarily truncate the value of 'selective' to int.
10334 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10336 * composite.c: Don't truncate sizes to 'int'.
10337 (composition_gstring_p, composition_reseat_it)
10338 (composition_adjust_point): Use EMACS_INT, not int.
10339 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10340 not EMACS_UINT, for indexes.
10342 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10344 * buffer.c: Include <verify.h>.
10345 (struct sortvec.priority, struct sortstr.priority):
10346 Now EMACS_INT, not int.
10347 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10348 (struct sortstr.size, record_overlay_string)
10349 (struct sortstrlist.size, struct sortlist.used):
10350 Don't truncate size to int.
10351 (record_overlay_string): Check for size-calculation overflow.
10352 (init_buffer_once): Check at compile-time, not run-time.
10354 2011-06-22 Jim Meyering <meyering@redhat.com>
10356 Don't leak an XBM-image-sized buffer
10357 * image.c (xbm_load): Free the image buffer after using it.
10359 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10362 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10363 that Sun C diagnosed.
10364 * fns.c (secure_hash): Fix pointer signedness issue.
10365 * intervals.c (static_offset_intervals): New function.
10366 (offset_intervals): Use it.
10368 2011-06-21 Leo Liu <sdl.web@gmail.com>
10371 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10374 * fns.c (secure_hash): Rename from crypto_hash_function and change
10375 the first arg to accept symbols.
10376 (Fsecure_hash): New primitive.
10377 (syms_of_fns): New symbols.
10379 2011-06-20 Deniz Dogan <deniz@dogan.se>
10381 * process.c (Fset_process_buffer): Clarify return value in
10384 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10386 * dispnew.c (add_window_display_history): Use BVAR.
10388 * xdisp.c (debug_method_add): Use BVAR.
10389 (check_window_end, dump_glyph_matrix, dump_glyph)
10390 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10392 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10395 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10396 check till after the cache is created in init_frame_faces.
10398 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10400 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10402 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10404 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10405 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10406 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10408 Improve buffer-overflow checking (Bug#8873).
10409 * fileio.c (Finsert_file_contents):
10410 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10411 Remove the old (too-loose) buffer overflow checks.
10412 They weren't needed, since make_gap checks for buffer overflow.
10413 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10414 The old code merely checked for Emacs fixnum overflow, and relied
10415 on undefined (wraparound) behavior. The new code avoids undefined
10416 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10418 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10419 Tune. Don't use wider integers than needed. Don't use alloca.
10420 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10422 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10424 * insdel.c, lisp.h (buffer_overflow): New function.
10425 (insert_from_buffer_1, replace_range, replace_range_2):
10426 * insdel.c (make_gap_larger):
10427 * editfns.c (Finsert_char):
10428 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10430 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10432 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10434 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10436 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10437 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10439 * fileio.c: Don't assume EMACS_INT fits in off_t.
10440 (emacs_lseek): New static function.
10441 (Finsert_file_contents, Fwrite_region): Use it.
10442 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10444 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10446 * fns.c: Don't overflow int when computing a list length.
10447 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10448 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10449 truncation on 64-bit hosts. Check for QUIT every
10450 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10451 faster and is responsive enough.
10452 (Flength): Report an error instead of overflowing an integer.
10453 (Fsafe_length): Return a float if the value is not representable
10454 as a fixnum. This shouldn't happen except in contrived situations.
10455 (Fnthcdr, Fsort): Don't assume list length fits in int.
10456 (Fcopy_sequence): Don't assume vector length fits in int.
10458 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10459 (header_size, word_size): New constants.
10460 (allocate_vectorlike): Don't check size overflow here.
10461 (allocate_vector): Check it here instead, since this is the only
10462 caller of allocate_vectorlike that could cause overflow.
10463 Check that the new vector's length is representable as a fixnum.
10465 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10466 The previous code was bogus. For example, next_almost_prime (32)
10467 returned 39, which is undesirable as it is a multiple of 3; and
10468 next_almost_prime (24) returned 25, which is a multiple of 5 so
10469 why was the code bothering to check for multiples of 7?
10471 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10473 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10475 Variadic C functions now count arguments with ptrdiff_t.
10476 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10477 Back then I didn't know that the Emacs coding style prefers signed int.
10478 Also, in the meantime I found a few more instances where arguments
10479 were being counted with int, which may truncate counts on 64-bit
10480 machines, or EMACS_INT, which may be unnecessarily wide.
10481 * lisp.h (struct Lisp_Subr.function.aMANY)
10482 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10483 Arg counts are now ptrdiff_t, not size_t.
10484 All variadic functions and their callers changed accordingly.
10485 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10486 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10487 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10488 * callint.c (Fcall_interactively): Check arg count for overflow,
10489 to avoid potential buffer overrun. Use signed char, not 'int',
10490 for 'varies' array, so that we needn't bother to check its size
10491 calculation for overflow.
10492 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10493 * eval.c (apply_lambda):
10494 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10495 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10496 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10498 * callint.c (Fcall_interactively): Don't use index var as event count.
10500 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10501 * mem-limits.h (SIZE): Remove; no longer used.
10503 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10505 Remove unnecessary casts.
10506 * xterm.c (x_term_init):
10507 * xfns.c (x_set_border_pixel):
10508 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10509 These aren't needed now that we assume ANSI C.
10511 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10512 It's more likely to cause problems (due to unsigned overflow)
10515 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10517 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10519 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10521 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10523 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10525 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10527 GLYPH_CODE_FACE returns EMACS_INT, not int.
10528 * dispextern.h (merge_faces):
10529 * xfaces.c (merge_faces):
10530 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10531 Don't assume EMACS_INT fits in int.
10533 * character.h (CHAR_VALID_P): Remove unused parameter.
10534 * fontset.c, lisp.h, xdisp.c: All uses changed.
10536 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10538 * fns.c (concat): Minor tuning based on overflow analysis.
10539 This doesn't fix any bugs. Use int to hold character, instead
10540 of constantly refetching from Emacs object. Use XFASTINT, not
10541 XINT, for value known to be a character. Don't bother comparing
10542 a single byte to 0400, as it's always less.
10544 * floatfns.c (Fexpt):
10545 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10547 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10550 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10552 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10553 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10554 incorrectly succeed when S was a string, because 4294967386 was
10555 truncated before it was used.
10557 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10558 Otherwise, an out-of-range integer could cause undefined behavior
10561 * composite.c: Use int, not EMACS_INT, for characters.
10562 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10563 EMACS_INT, for values that are known to be in character range.
10564 This doesn't fix any bugs but is the usual style inside Emacs and
10565 may generate better code on 32-bit machines.
10567 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10568 This is for reasons similar to the recent CHAR_STRING fix.
10569 * charset.c (Fencode_char): Check that character arg is actually
10570 a character. Pass an int to ENCODE_CHAR.
10571 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10572 wider than 'int', as a compile-time check to prevent future regressions
10575 * character.c (char_string): Remove unnecessary casts.
10577 Make sure a 64-bit char is never passed to CHAR_STRING.
10578 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10579 by silently ignoring the top 32 bits, allowing some values
10580 that were far too large to be valid characters.
10581 * character.h: Include <verify.h>.
10582 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10583 arguments are no wider than unsigned, as a compile-time check
10584 to prevent future regressions in this area.
10586 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10587 (Fsubst_char_in_region):
10589 * xdisp.c (decode_mode_spec_coding):
10590 Adjust to CHAR_STRING's new requirement.
10591 * editfns.c (Finsert_char, Fsubst_char_in_region):
10592 * fns.c (concat): Check that character args are actually
10593 characters. Without this test, these functions did the wrong
10594 thing with wildly out-of-range values on 64-bit hosts.
10596 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10597 These casts should not be needed on 32-bit hosts, either.
10598 * keyboard.c (read_char):
10599 * lread.c (Fload): Remove casts to unsigned.
10601 * lisp.h (UNSIGNED_CMP): New macro.
10602 This fixes comparison bugs on 64-bit hosts.
10603 (ASCII_CHAR_P): Use it.
10604 * casefiddle.c (casify_object):
10605 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10606 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10607 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10608 * dispextern.h (FACE_FROM_ID):
10609 * keyboard.c (read_char): Use UNSIGNED_CMP.
10611 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10612 not to EMACS_INT, to avoid GCC warning.
10614 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10616 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10617 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10618 isn't needed on 32-bit machines.
10620 * buffer.c (Fgenerate_new_buffer_name):
10621 Use EMACS_INT for count, not int.
10622 (advance_to_char_boundary): Return EMACS_INT, not int.
10624 * data.c (Qcompiled_function): Now static.
10626 * window.c (window_body_lines): Now static.
10628 * image.c (gif_load): Rename local to avoid shadowing.
10630 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10631 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10632 * alloc.c (make_save_value): Integer argument is now of type
10633 ptrdiff_t, not int.
10634 (mark_object): Use ptrdiff_t, not int.
10635 * lisp.h (pD): New macro.
10636 * print.c (print_object): Use it.
10638 * alloc.c: Use EMACS_INT, not int, to count objects.
10639 (total_conses, total_markers, total_symbols, total_vector_size)
10640 (total_free_conses, total_free_markers, total_free_symbols)
10641 (total_free_floats, total_floats, total_free_intervals)
10642 (total_intervals, total_strings, total_free_strings):
10643 Now EMACS_INT, not int. All uses changed.
10644 (Fgarbage_collect): Compute overall total using a double, so that
10645 integer overflow is less likely to be a problem. Check for overflow
10646 when converting back to an integer.
10647 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10648 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10649 These were 'int' variables that could overflow on 64-bit hosts;
10650 they were never used, so remove them instead of repairing them.
10651 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10652 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10653 Previously, this ceilinged at INT_MAX, but that doesn't work on
10655 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10657 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10658 (allocate_vectorlike): Check for ptrdiff_t overflow.
10659 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10660 when a (possibly-narrower) signed value would do just as well.
10661 We prefer using signed arithmetic, to avoid comparison confusion.
10663 * alloc.c: Catch some string size overflows that we were missing.
10664 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10665 for convenience in STRING_BYTES_MAX.
10666 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10667 The definition here is exact; the one in lisp.h was approximate.
10668 (allocate_string_data): Check for string overflow. This catches
10669 some instances we weren't catching before. Also, it catches
10670 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10671 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10672 and ptrdiff_t and EMACS_INT are both 64 bits.
10674 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10675 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10676 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10678 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10680 * alloc.c (Fmake_string): Check for out-of-range init.
10682 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10684 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10686 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10688 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10689 xg_get_default_scrollbar_width.
10691 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10692 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10693 (style_changed_cb): Call update_theme_scrollbar_width and call
10694 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10695 all frames (Bug#8505).
10696 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10697 Call gtk_window_set_resizable if HAVE_GTK3.
10698 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10699 and height if HAVE_GTK3 (Bug#8505).
10700 (scroll_bar_width_for_theme): New variable.
10701 (update_theme_scrollbar_width): New function.
10702 (xg_get_default_scrollbar_width): Move code to
10703 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10704 (xg_initialize): Call update_theme_scrollbar_width.
10706 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10708 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10710 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10712 * frame.c (make_frame): Call other_buffer_safely instead of
10715 * window.c (temp_output_buffer_show): Call display_buffer with
10716 second argument Vtemp_buffer_show_specifiers and reset latter
10717 immediately after the call.
10718 (Vtemp_buffer_show_specifiers): New variable.
10719 (auto_window_vscroll_p, next_screen_context_lines)
10720 (Vscroll_preserve_screen_position): Remove leading asterisks from
10723 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10725 Fix minor problems found by GCC 4.6.0 static checking.

10727 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10728 (record_buffer): Remove unused local.
10729 * frame.c (other_visible_frames, frame_buffer_list): Now static.

10740 (update_hints_inhibit): Remove; never set. All uses removed.
10741 * widgetprv.h (emacsFrameClassRec): Remove decl.
10742 * window.c (delete_deletable_window): Now returns void, since it
10743 wasn't returning anything.
10744 (compare_window_configurations): Remove unused locals.
10745 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10746 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10747 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10748 the same widths as pointers. This follows up on the 2011-05-06 patch.
10749 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.

10760 * image.c (gif_load): Add animation frame delay to the metadata.
10761 (syms_of_image): Use DEFSYM. New symbol `delay'.
10763 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10765 * window.c (delete_deletable_window): Re-add.
10766 (Fset_window_configuration): Rewrite to handle dead buffers and
10767 consequently deletable windows.
10768 (window_tree, Fwindow_tree): Remove. Supply functionality in
10770 (compare_window_configurations): Simplify code.
10772 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10774 * image.c (imagemagick_load_image): Fix type mismatch.

10779 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10781 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10782 Qclone_number. Remove external declaration of Qdelete_window.
10783 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10785 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10786 Run Qbuffer_list_update_hook if allowed.

10788 buffer list implementation.
10789 (other_buffer_safely): New function.

10795 functions. Run Qbuffer_list_update_hook if allowed.
10796 (Frecord_buffer, Funrecord_buffer): New functions.
10797 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10798 Move switch-to-buffer to window.el.
10799 (bury-buffer): Move to window.el.
10800 (Vbuffer_list_update_hook): New variable.

10811 declaration of select_count.
10812 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10813 (Fother_window): Move to window.el.

10896 match the prototype.
10898 2011-06-10 Martin Rudalics <rudalics@gmx.at>
10900 * window.c: Remove declarations of Qwindow_size_fixed,
10901 window_min_size_1, window_min_size_2, window_min_size,
10902 size_window, window_fixed_size_p, enlarge_window, delete_window.
10903 Remove static from declaration of Qdelete_window, it's
10904 temporarily needed by Fbury_buffer.
10905 (replace_window): Don't assign orig_top_line and
10907 (Fdelete_window, delete_window): Remove. Window deletion is

10909 (window_loop): Remove DELETE_OTHER_WINDOWS case.
10910 Replace Fdelete_window calls with calls to Qdelete_window.
10911 (Fdelete_other_windows): Remove. Deleting other windows is
10912 handled by window.el.

11284 value of a `display' property is a "replacing spec".
11285 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11286 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11316 * gnutls.c: Use Emacs's memory allocators.
11317 Without this change, the gnutls library would invoke malloc etc.
11318 directly, which causes problems on non-SYNC_INPUT hosts, and which
11319 runs afoul of improving memory_full behavior. (Bug#8761)
11320 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11321 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11322 xfree instead of the default malloc, realloc, free.
11323 (Fgnutls_boot): No need to check for memory allocation failure,
11324 since xmalloc does that for us.

11343 (xpm_put_color_table_h):
11344 * lisp.h (struct Lisp_Hash_Table):
11345 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11346 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11347 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11348 * alloc.c (allocate_vectorlike):
11349 Check for overflow in vector size calculations.
11350 * ccl.c (ccl_driver):
11351 Check for overflow when converting EMACS_INT to int.
11352 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11353 need to be updated by these changes.
11354 * fns.c (make_hash_table, maybe_resize_hash_table):
11355 Check for integer overflow with large hash tables.
11356 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11357 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11358 (SXHASH_REDUCE): New macro.
11359 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11360 Use it instead of discarding useful hash info with large hash values.
11361 (sxhash_float): New function.
11362 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11363 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11364 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11365 Rewrite to use FIXNUM_BITS, as this simplifies things.
11366 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11367 Adjust signatures to match updated version of code.
11368 (consing_since_gc): Now EMACS_INT, since a single hash table can
11369 use more than INT_MAX bytes.
11371 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11373 Make it possible to build with GCC-4.6+ -O2 -flto.

11377 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11379 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11380 Call minibuffer-inactive-mode.
11382 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11384 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11385 Update dependencies.
11387 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11389 * data.c (init_data): Remove code for UTS, this system is not
11392 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11394 Don't force ./temacs to start in terminal mode.
11396 * frame.c (make_initial_frame): Initialize faces in all cases, not
11397 only when CANNOT_DUMP is defined.
11398 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11400 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11402 * dispnew.c (add_window_display_history): Use const for the string
11403 pointer. Remove declaration, not needed.
11405 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11407 Use 'inline', not 'INLINE'.
11408 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11409 * alloc.c, fontset.c (INLINE): Remove.
11410 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11411 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11412 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11413 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11414 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11416 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11418 Make it possible to run ./temacs.
11420 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11421 syms_of_callproc does the same thing. Remove test for
11422 "initialized", do it in the caller.
11423 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11425 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11427 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11428 (read_minibuf): Use get_minibuffer.
11429 (syms_of_minibuf): Use DEFSYM.
11430 (Qmetadata): New var.
11431 * data.c (Qbuffer): Don't make it static.
11432 (syms_of_data): Use DEFSYM.
11434 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11436 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11437 (CCL_CODE_MIN): New macro.
11439 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11441 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11443 * eval.c (Qdebug): Now static.
11444 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11445 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11446 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11448 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11450 * image.c: Various fixes to ImageMagick code comments.
11451 (Fimagemagick_types): Doc fix.
11453 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11455 Minor fixes prompted by GCC 4.6.0 warnings.
11457 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11459 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11460 (x_clipboard_manager_save_all): Move extern decl to ...
11461 * xterm.h: ... here, so that it can be checked for consistency.
11463 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11465 * xselect.c (x_clipboard_manager_save_frame)
11466 (x_clipboard_manager_save_all): New functions.
11467 (Fx_clipboard_manager_save): Lisp function deleted.
11469 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11470 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11472 * xterm.h: Update prototype.
11474 2011-05-28 William Xu <william.xwl@gmail.com>
11476 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11477 exiting (Bug#8239).
11479 2011-05-28 Jim Meyering <meyering@redhat.com>
11481 Avoid a sign-extension bug in crypto_hash_function.
11482 * fns.c (to_uchar): Define.
11483 (crypto_hash_function): Use it to convert some newly-signed
11484 variables to unsigned, to avoid sign-extension bugs. For example,
11485 without this change, (md5 "truc") would evaluate to
11486 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11487 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11488 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11490 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11492 Integer overflow fixes.
11494 * dbusbind.c: Serial number integer overflow fixes.
11495 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11496 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11497 to hold a serial number that is too large for a fixnum.
11498 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11499 Check for serial numbers out of range. Decode any serial number
11500 that was so large that it became a float. (Bug#8722)
11502 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11503 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11504 Use XFASTINT rather than XUINT when numbers are nonnegative.
11505 (xd_append_arg, Fdbus_method_return_internal):
11506 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11507 arguments, check that Lisp number is nonnegative, rather than
11508 silently wrapping negative numbers around. (Bug#8722)
11509 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11512 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11514 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11516 ccl: Add integer overflow checks.
11517 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11518 (IN_INT_RANGE): New macros.
11519 (ccl_driver): Use them to check for integer overflow when
11520 decoding a CCL program. Many of the new checks are whether XINT (x)
11521 fits in int; it doesn't always, on 64-bit hosts. The new version
11522 doesn't catch all possible integer overflows, but it's an
11523 improvement. (Bug#8719)
11525 * alloc.c (make_event_array): Use XINT, not XUINT.
11526 There's no need for unsigned here.
11528 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11529 This follows up to the 2011-05-06 change that substituted uintptr_t
11530 for EMACS_INT. This case wasn't caught back then.
11532 Rework Fformat to avoid integer overflow issues.
11533 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11534 now (part of C89). Include <verify.h>.
11535 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11536 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11537 (Fformat): Avoid the prepass trying to compute sizes; it was only
11538 approximate and thus did not catch overflow reliably. Instead, walk
11539 through the format just once, formatting and computing sizes as we go,
11540 checking for integer overflow at every step, and allocating a larger
11541 buffer as needed. Keep track separately whether the format is
11542 multibyte. Keep only the most-recently calculated precision, rather
11543 than them all. Record whether each argument has been converted to
11544 string. Use EMACS_INT, not int, for byte and char and arg counts.
11545 Support field widths and precisions larger than INT_MAX. Avoid
11546 sprintf's undefined behavior with conversion specifications such as %#d
11547 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11548 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11549 formatting out-of-range floating point numbers with int
11550 formats. (Bug#8668)
11552 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11554 * data.c: Avoid integer truncation in expressions involving floats.
11555 * data.c: Include <intprops.h>.
11556 (arith_driver): When there's an integer overflow in an expression
11557 involving floating point, convert the integers to floating point
11558 so that the resulting value does not suffer from catastrophic
11559 integer truncation. For example, on a 64-bit host (* 4
11560 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11561 Do not rely on undefined behavior after integer overflow.
11563 merge count_size_as_multibyte, parse_str_to_multibyte
11564 * character.c, character.h (count_size_as_multibyte):
11565 Rename from parse_str_to_multibyte; all uses changed.
11566 Check for integer overflow.
11567 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11568 since it's now a duplicate of the other. This is more of
11569 a character than a buffer op, so better that it's in character.c.
11570 * fns.c, print.c: Adjust to above changes.
11572 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11574 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11576 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11578 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11579 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11580 (x_clipboard_manager_save): Now static.
11581 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11583 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11584 (crypto_hash_function): Now static.
11585 Fix pointer signedness problems. Avoid unnecessary initializations.
11587 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11589 * termhooks.h (Vselection_alist): Make it terminal-local.
11591 * terminal.c (create_terminal): Initialize it.
11593 * xselect.c: Support for clipboard managers.
11594 (Vselection_alist): Move to termhooks.h as terminal-local var.
11595 (LOCAL_SELECTION): New macro.
11596 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11597 (symbol_to_x_atom): Remove gratuitous arg.
11598 (x_handle_selection_request, lisp_data_to_selection_data)
11599 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11600 (x_own_selection, x_get_local_selection, x_convert_selection):
11601 New arg, specifying work frame. Use terminal-local Vselection_alist.
11602 (some_frame_on_display): Delete unused function.
11603 (Fx_own_selection_internal, Fx_get_selection_internal)
11604 (Fx_disown_selection_internal, Fx_selection_owner_p)
11605 (Fx_selection_exists_p): New optional frame arg.
11606 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11607 (x_handle_selection_clear): Don't treat other terminals with the
11608 same keyboard specially. Use the terminal-local Vselection_alist.
11609 (x_clear_frame_selections): Use Frun_hook_with_args.
11611 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11613 * xterm.h: Add support for those atoms.
11615 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11617 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11618 (converted_selections, conversion_fail_tag): New global variables.
11619 (x_selection_request_lisp_error): Free the above.
11620 (x_get_local_selection): Remove unnecessary code.
11621 (x_reply_selection_request): Args changed; handle arbitrary array
11622 of converted selections stored in converted_selections.
11623 Separate the XChangeProperty and SelectionNotify steps.
11624 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11625 (x_convert_selection): New function.
11626 (x_handle_selection_event): Simplify.
11627 (x_get_foreign_selection): Don't ignore incoming requests while
11628 waiting for an answer; this will fail when we implement
11629 SAVE_TARGETS, and seems unnecessary anyway.
11630 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11631 (Vx_sent_selection_functions): Doc fix.
11633 2011-05-26 Leo Liu <sdl.web@gmail.com>
11635 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11637 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11639 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11641 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11642 for fringe update if it has periodic bitmap.
11643 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11644 and fringe_bitmap_periodic_p.
11646 * fringe.c (get_fringe_bitmap_data): New function.
11647 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11648 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11649 row. Mark glyph row for fringe update if periodicity changed.
11651 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11652 for fringe update unless it has periodic bitmap.
11654 2011-05-25 Kenichi Handa <handa@m17n.org>
11656 * xdisp.c (get_next_display_element): Set correct it->face_id for
11657 a static composition.
11659 2011-05-24 Leo Liu <sdl.web@gmail.com>
11662 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.

11670 * gnutls.c: Remove unused macros.
11671 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11672 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11673 Remove macros that are defined and never used.
11674 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11676 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11678 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11679 (Fx_get_selection_internal): Minor cleanup.
11680 (Fx_own_selection_internal): Rename arguments for consistency with
11683 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11685 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11687 2011-05-22 Chong Yidong <cyd@stupidchicken.com>

11704 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11705 report_file_error introduced by the change from 2011-05-07.
11707 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11709 * systime.h (Time): Define only if emacs is defined.
11710 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11711 where the include path doesn't have X11/X.h by default. See
11712 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11714 2011-05-20 Kenichi Handa <handa@m17n.org>
11716 * composite.c (find_automatic_composition): Fix previous change.
11718 2011-05-20 Glenn Morris <rgm@gnu.org>
11720 * lisp.mk: New file, split from Makefile.in.
11721 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11722 (shortlisp): Remove.
11723 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11725 2011-05-19 Glenn Morris <rgm@gnu.org>
11727 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11728 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11729 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11730 (lisp): Set the order to that of loadup.el.
11731 (shortlisp): Make it a copy of $lisp.
11732 (SOME_MACHINE_LISP): Remove.
11733 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11734 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11736 2011-05-18 Kenichi Handa <handa@m17n.org>
11738 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11739 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11740 (find_automatic_composition): Mostly rewrite for efficiency.
11742 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11744 * makefile.w32-in: Update dependencies.
11746 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11748 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11749 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11751 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11753 Fix some integer overflow issues, such as string length overflow.
11755 * insdel.c (count_size_as_multibyte): Check for string overflow.
11757 * character.c (lisp_string_width): Check for string overflow.
11758 Use EMACS_INT, not int, for string indexes and lengths; in
11759 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11760 the resulting string length overflows an EMACS_INT; instead,
11761 report a string overflow if no precision given. When checking for
11762 precision exhaustion, use a check that cannot possibly have
11763 integer overflow. (Bug#8675)
11764 * character.h (lisp_string_width): Adjust to new signature.
11766 * alloc.c (string_overflow): New function.
11767 (Fmake_string): Use it. This doesn't change behavior, but saves
11768 a few bytes and will simplify future changes.
11769 * character.c (string_escape_byte8): Likewise.
11770 * lisp.h (string_overflow): New decl.
11772 Fixups, following up to the user-interface timestamp change.
11773 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11774 for UI timestamps, instead of unsigned long.
11775 * msdos.c (mouse_get_pos): Likewise.
11776 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11777 * w32gui.h (Time): Define by including "systime.h" rather than by
11778 declaring it ourselves. (Bug#8664)
11780 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11781 * image.c (clear_image_cache): Likewise.
11783 * term.c (term_mouse_position): Don't assume time_t wraparound.
11785 Be more systematic about user-interface timestamps.
11786 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11787 and sometimes 'EMACS_UINT', to represent these timestamps.
11788 This change causes it to use 'Time' uniformly, as that's what X uses.
11789 This makes the code easier to follow, and makes it easier to catch
11790 integer overflow bugs such as Bug#8664.
11791 * frame.c (Fmouse_position, Fmouse_pixel_position):
11792 Use Time, not unsigned long, for user-interface timestamps.
11793 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11794 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11795 * keyboard.h (last_event_timestamp): Likewise.
11796 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11797 * menu.h (xmenu_show): Likewise.
11798 * term.c (term_mouse_position): Likewise.
11799 * termhooks.h (struct input_event.timestamp): Likewise.
11800 (struct terminal.mouse_position_hook): Likewise.
11801 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11802 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11803 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11804 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11805 what it was before.
11806 * menu.h, termhooks.h: Include "systime.h", for Time.
11808 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11809 Don't assume that the difference between two unsigned long values
11810 can fit into an integer. At this point, we know button_down_time
11811 <= event->timestamp, so the difference must be nonnegative, so
11812 there's no need to cast the result if double-click-time is
11813 nonnegative, as it should be; check that it's nonnegative, just in
11814 case. This bug is triggered when events are more than 2**31 ms
11815 apart (about 25 days). (Bug#8664)
11817 * xselect.c (last_event_timestamp): Remove duplicate decl.
11818 (x_own_selection): Remove needless cast to unsigned long.
11820 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11821 that always fit in int. Use a sentinel instead of a counter, to
11822 avoid a temp and to allay GCC's concerns about possible int overflow.
11823 * frame.h (struct frame): Use int for menu_bar_items_used
11824 instead of EMACS_INT, since it always fits in int.
11826 * menu.c (grow_menu_items): Check for int overflow.
11828 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11830 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11831 Before, the code was not consistent. These values cannot exceed
11832 2**31 - 1 so there's no need to make them unsigned.
11833 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11834 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11835 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11837 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11839 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11840 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11841 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11842 presumably because the widths might not match.
11844 * window.c (size_window): Avoid needless test at loop start.
11846 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11848 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11850 2011-05-12 Drew Adams <drew.adams@oracle.com>
11852 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11854 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11856 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11857 `width' to `bar_area_x' and `bar_area_width', respectively.
11858 (x_scroll_run): Take account of fringe background extension.
11860 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11861 Rename local vars `left' and `width' to `bar_area_x' and
11862 `bar_area_width', respectively.
11863 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11864 background extension.
11866 2011-05-10 Jim Meyering <meyering@redhat.com>
11868 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11870 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11872 * image.c (Finit_image_library): Return t for built-in image types,
11873 like pbm and xbm. (Bug#8640)
11875 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11877 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11879 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11881 * w32console.c (Fset_screen_color): Doc fix.
11882 (Fget_screen_color): New function.
11883 (syms_of_ntterm): Defsubr it.
11885 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11886 unlink the temporary file if Fcall_process didn't create it in the
11888 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11889 child process will be redirected to a file specified with `:file'.
11890 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11891 cue to call_process_cleanup not to close that handle.
11893 2011-05-07 Ben Key <bkey76@gmail.com>
11895 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11896 one of two shell specific rules, either bootstrap-temacs-CMD or
11897 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11898 to the previous implementation of the bootstrap-temacs rule.
11899 The bootstrap-temacs-CMD rule is similar to the previous
11900 implementation of the bootstrap-temacs rule except that it
11901 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11904 These changes, along with some changes to nt/configure.bat,
11905 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11906 earlier fix to add support for --cflags and --ldflags options
11907 that include quotes so that it works whether make uses cmd or
11910 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11912 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11913 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11915 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11916 a string. Handle both cases.
11917 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11918 (Fdbus_register_method): Use Qinvalid_function.
11920 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11922 * makefile.w32-in: Update dependencies.
11923 (LISP_H): Add inttypes.h and stdin.h.
11924 (PROCESS_H): Add unistd.h.
11926 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11928 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11929 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11931 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11933 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11935 * term.c (vfatal): Remove stray call to va_end.
11936 It's not needed and the C Standard doesn't allow it here anyway.
11938 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11939 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11941 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11944 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11946 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11948 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11950 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11952 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11954 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11955 * charset.c (Fdefine_charset_internal): Don't initialize
11956 charset.code_space[15]. The value was garbage, on hosts with
11957 32-bit int (Bug#8600).
11959 * lread.c (read_integer): Be more consistent with string-to-number.
11960 Use string_to_number to do the actual conversion; this avoids
11961 rounding errors and fixes some other screwups. Without this fix,
11962 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11963 (digit_to_number): Move earlier, for benefit of read_integer.
11964 Return -1 if the digit is out of range for the base, -2 if it is
11965 not a digit in any supported base. (Bug#8602)
11967 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11969 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11970 to match comment at start of function. This also removes a
11971 GCC warning about overflow in a 32+64-bit port.
11973 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11975 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11976 Reported by Stefan Monnier in
11977 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11978 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11979 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11981 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11982 (EMACS_UINTPTR): Likewise, with uintptr_t.
11984 * lisp.h: Prefer 64-bit EMACS_INT if available.
11985 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11986 on 32-bit hosts that have 64-bit int, so that they can access
11988 However, temporarily disable this change unless the temporary
11989 symbol WIDE_EMACS_INT is defined.
11991 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11993 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11994 This removes an assumption that EMACS_INT and long are the same
11995 width as pointers. The assumption is true for Emacs porting targets
11996 now, but we want to make other targets possible.
11997 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11998 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11999 In the rest of the code, change types of integers that hold casted
12000 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12001 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12002 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12003 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12004 No need to cast type when ORing.
12005 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12006 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12007 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12008 assume EMACS_INT is the same width as char *.
12009 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12010 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12011 Remove no-longer-needed casts.
12012 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12013 (xg_tool_bar_help_callback, xg_make_tool_item):
12014 Use EMACS_INTPTR to hold an integer
12015 that will be cast to void *; this can avoid a GCC warning
12016 if EMACS_INT is not the same width as void *.
12017 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12018 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12019 (current_message_1, set_message_1):
12020 Use a local to convert to proper width without a cast.
12021 * xmenu.c (dialog_selection_callback): Likewise.
12023 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12024 Also, don't assume VALBITS / RAND_BITS is less than 5,
12025 and don't rely on undefined behavior when shifting a 1 left into
12027 * lisp.h (get_random): Change signature to match.
12029 * lread.c (hash_string): Use size_t, not int, for hash computation.
12030 Normally we prefer signed values; but hashing is special, because
12031 it's better to use unsigned division on hash table sizes so that
12032 the remainder is nonnegative. Also, size_t is the natural width
12033 for hashing into memory. The previous code used 'int', which doesn't
12034 retain enough info to hash well into very large tables.
12035 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12037 * dbusbind.c: Don't possibly lose pointer info when converting.
12038 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12039 Use XPNTR rather than XHASH, so that the high-order bits of
12040 the pointer aren't lost when converting through void *.
12042 * eval.c (Fautoload): Don't double-shift a pointer.
12044 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12046 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12048 * gnutls.c (DEF_GNUTLS_FN):
12049 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12051 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12053 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12056 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12058 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12059 New version that can reserve upto 2GB of heap space.
12061 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12063 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12065 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12067 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12068 `gnutls_certificate_set_x509_key_file'.
12070 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12072 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12073 Update dependencies.
12075 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12077 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12078 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12079 Remove unused parameter `fildes'.
12080 * process.c (read_process_output, send_process): Don't pass it.
12082 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12084 Fix previous change: the library cache is defined in w32.c.
12085 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12086 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12088 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12090 Implement dynamic loading of GnuTLS on Windows.
12092 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12093 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12094 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12097 * gnutls.c (Qgnutls_dll): Define.
12098 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12099 (gnutls_*): Declare function pointers.
12100 (init_gnutls_functions): New function to initialize function pointers.
12101 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12102 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12103 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12104 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12105 (emacs_gnutls_write, emacs_gnutls_read)
12106 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12107 (Fgnutls_available_p): New function.
12108 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12109 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12110 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12112 * image.c: Include w32.h.
12113 (Vimage_type_cache): Delete.
12114 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12115 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12116 (w32_delayed_load): Move to w32.c.
12118 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12120 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12121 (w32_delayed_load): Move from image.c. When loading a library, record
12122 its filename in the :loaded-from property of the library id.
12123 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12124 Initialize and staticpro them.
12125 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12127 * process.c: Include lisp.h before w32.h, not after.
12128 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12129 instead of gnutls_record_check_pending.
12131 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12133 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12135 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12136 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12139 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12141 * xterm.c (x_set_frame_alpha): Do not set property on anything
12142 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12144 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12146 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12148 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12150 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12151 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12157 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12158 (Qgnutls_bootprop_callbacks_verify): Make static.
12160 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12162 * callproc.c: Indentation fixup.
12164 * sysdep.c (wait_for_termination_1): Make static.
12165 (wait_for_termination, interruptible_wait_for_termination):
12166 Move after wait_for_termination_1.
12168 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12170 * sysdep.c (interruptible_wait_for_termination): New function
12171 which is like wait_for_termination, but allows keyboard
12174 * callproc.c (Fcall_process): Add (:file "file") as an option for
12176 (Fcall_process_region): Ditto.
12178 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12180 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12181 rather than `XVECTOR (FOO)->size'.
12183 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12184 inttypes.h, as a gnulib replacement is used if it not available in
12187 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12189 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12190 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12191 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12193 * coding.c (coding_alloc_by_realloc): Error out if destination
12194 will grow beyond MOST_POSITIVE_FIXNUM.
12195 (decode_coding_emacs_mule): Abort if there isn't enough place in
12196 charbuf for the composition carryover bytes. Reserve an extra
12197 space for up to 2 characters produced in a loop.
12198 (decode_coding_iso_2022): Abort if there isn't enough place in
12199 charbuf for the composition carryover bytes.
12201 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12203 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12204 aborting when %lld or %lll format is passed.
12205 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12206 %llo or %llx format is passed. (Bug#8545)
12208 * window.c (window_scroll_line_based): Use a marker instead of
12209 simple variables to record original value of point. (Bug#7952)
12211 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12212 produced by %s or %c overflows available buffer space. (Bug#8545)
12214 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12216 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12217 (SIZE_MAX): Move defn after all includes, as they might #define it.
12219 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12221 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12223 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12225 * keyboard.c (Qdelayed_warnings_hook): Define.
12226 (command_loop_1): Run `delayed-warnings-hook'
12227 if Vdelayed_warnings_list is non-nil.
12228 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12229 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12231 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12233 * doprnt.c (doprnt): Don't return value smaller than the buffer
12234 size if the message was truncated. (Bug#8545).
12236 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12238 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12239 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12241 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12243 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12245 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12247 * makefile.w32-in: Update dependencies.
12249 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12251 Improve `doprnt' and its usage. (Bug#8545)
12252 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12253 `format_end'. Remove support for %l as a conversion specifier.
12254 Don't use xrealloc. Improve diagnostics when the %l size modifier
12255 is used. Update the commentary.
12257 * eval.c (verror): Simplify calculation of size_t.
12259 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12262 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12264 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12267 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12269 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12270 This makes this file independent of the recent pseudovector change.
12272 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12274 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12276 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12277 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12278 Remove unused local.
12279 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12281 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12282 GCC 4.6.0 optimizes based on type-based alias analysis.
12283 For example, if b is of type struct buffer * and v of type struct
12284 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12285 != &v->size, and therefore "v->size = 1; b->size = 2; return
12286 v->size;" must therefore return 1. This assumption is incorrect
12287 for Emacs, since it type-puns struct Lisp_Vector * with many other
12288 types. To fix this problem, this patch adds a new type struct
12289 vectorlike_header that documents the constraints on layout of vectors
12290 and pseudovectors, and helps optimizing compilers not get fooled
12291 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12292 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12293 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12295 (XSETPVECTYPE): Rewrite in terms of new macro.
12296 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12297 This is a bit clearer, and further avoids the possibility of
12298 undesirable aliasing.
12299 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12300 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12301 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12302 since Lisp_Subr is a special case (no "next" field).
12303 (ASIZE): Now uses header.size rather than size.
12304 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12305 to avoid the hassle of writing XVECTOR (foo)->header.size.
12306 (struct vectorlike_header): New type.
12307 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12308 object, to help avoid aliasing.
12309 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12310 (SUBRP): Likewise, since Lisp_Subr is a special case.
12311 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12312 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12313 (struct Lisp_Hash_Table): Combine first two members into a single
12314 struct vectorlike_header member. All uses of "size" and "next" members
12315 changed to be "header.size" and "header.next".
12316 * buffer.h (struct buffer): Likewise.
12317 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12318 * frame.h (struct frame): Likewise.
12319 * process.h (struct Lisp_Process): Likewise.
12320 * termhooks.h (struct terminal): Likewise.
12321 * window.c (struct save_window_data, struct saved_window): Likewise.
12322 * window.h (struct window): Likewise.
12323 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12324 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12325 * buffer.c (init_buffer_once): Likewise.
12326 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12328 * process.c (Fformat_network_address): Use local var for size,
12331 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12333 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12334 * data.c (atof): Remove decl; no longer used or needed.
12335 (digit_to_number): Move to lread.c.
12336 (Fstring_to_number): Use new string_to_number function, to be
12337 consistent with how the Lisp reader treats infinities and NaNs.
12338 Do not assume that floating-point numbers represent EMACS_INT
12339 without losing information; this is not true on most 64-bit hosts.
12340 Avoid double-rounding errors, by insisting on integers when
12341 parsing non-base-10 numbers, as the documentation specifies.
12342 * lisp.h (string_to_number): New decl, replacing ...
12343 (isfloat_string): Remove.
12344 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12345 (read1): Do not accept +. and -. as integers; this
12346 appears to have been a coding error. Similarly, do not accept
12347 strings like +-1e0 as floating point numbers. Do not report
12348 overflow for integer overflows unless the base is not 10 which
12349 means we have no simple and reliable way to continue.
12350 Break out the floating-point parsing into a new
12351 function string_to_number, so that Fstring_to_number parses
12352 floating point numbers consistently with the Lisp reader.
12353 (digit_to_number): Move here from data.c. Make it static inline.
12354 (E_CHAR, EXP_INT): Remove, replacing with ...
12355 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12356 (string_to_number): New function, replacing isfloat_string.
12357 This function checks for valid syntax and produces the resulting
12358 Lisp float number too. Rework it so that string-to-number
12359 no longer mishandles examples like "1.0e+". Use strtoumax,
12360 so that overflow for non-base-10 numbers is reported only when
12361 there's no portable and simple way to convert to floating point.
12363 * textprop.c (set_text_properties_1): Rewrite for clarity,
12364 and to avoid GCC warning about integer overflow.
12366 * intervals.h (struct interval): Use EMACS_INT for members
12367 where EMACS_UINT might cause problems. See
12368 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12369 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12370 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12372 (offset_intervals): Tell GCC not to worry about length overflow
12373 when negating a negative length.
12375 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12376 (overrun_check_free): Likewise.
12378 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12379 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12382 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12383 (gnutls_make_error): Rename local to avoid shadowing.
12384 (gnutls_emacs_global_deinit): ifdef out; not used.
12385 (Fgnutls_boot): Use const for pointer to readonly storage.
12386 Comment out unused local. Fix pointer signedness problems.
12388 * lread.c (openp): Don't stuff size_t into an 'int'.
12389 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12390 about possible signed overflow.
12392 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12393 (GDK_KEY_g): Don't define if already defined.
12394 (xg_prepare_tooltip): Avoid pointer signedness problem.
12395 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12397 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12398 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12400 * xfns.c (Fx_window_property): Simplify a bit,
12401 to make a bit faster and to avoid GCC 4.6.0 warning.
12402 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12404 * fns.c (internal_equal): Don't assume size_t fits in int.
12406 * alloc.c (compact_small_strings): Tighten assertion a little.
12408 Replace pEd with more-general pI, and fix some printf arg casts.
12409 * lisp.h (pI): New macro, generalizing old pEd macro to other
12410 conversion specifiers. For example, use "...%"pI"d..." rather
12411 than "...%"pEd"...".
12412 (pEd): Remove. All uses replaced with similar uses of pI.
12413 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12414 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12415 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12416 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12417 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12418 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12419 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12421 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12422 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12423 * print.c (safe_debug_print, print_object): Likewise.
12424 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12426 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12427 avoiding the 0 flag, which is not portable.
12428 * process.c (Fmake_network_process): Use pI to avoid cast.
12429 * region-cache.c (pp_cache): Likewise.
12430 * xdisp.c (decode_mode_spec): Likewise.
12431 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12432 behavior on 64-bit hosts with printf arg.
12433 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12434 (x_stop_queuing_selection_requests): Likewise.
12435 (x_get_window_property): Don't truncate byte count to an 'int'
12438 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12439 here, since it parses constructs like leading '-' and spaces,
12440 which are not wanted; and it overflows with large numbers.
12441 Instead, simply match F[0-9]+, which is what is wanted anyway.
12443 * alloc.c: Remove unportable assumptions about struct layout.
12444 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12445 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12446 (allocate_vectorlike, make_pure_vector): Use the new macros,
12447 plus offsetof, to remove unportable assumptions about struct layout.
12448 These assumptions hold on all porting targets that I know of, but
12449 they are not guaranteed, they're easy to remove, and removing them
12450 makes further changes easier.
12452 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12453 This doesn't fix a bug but makes the code clearer.
12454 (string_overrun_cookie): Now const. Use initializers that
12455 don't formally overflow signed char, to avoid warnings.
12456 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12457 can cause Emacs to crash when string overrun checking is enabled.
12458 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12459 multiple of sizeof (EMACS_INT); it need not be, if
12460 alignof(EMACS_INT) < sizeof (EMACS_INT).
12461 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12463 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12465 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12467 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12469 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12470 supposed to be handshaking. (Bug#8556)
12471 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12473 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12475 * lisp.h (Qdebug): List symbol.
12476 * eval.c (Qdebug): Restore global linkage.
12477 * keyboard.c (debug-on-event): New variable.
12478 (handle_user_signal): Break into debugger when debug-on-event
12479 matches the current signal symbol.
12481 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12483 * alloc.c (check_sblock, check_string_bytes)
12484 (check_string_free_list): Convert to standard C.
12486 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12488 * w32.c (emacs_gnutls_push): Fix typo.
12490 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12492 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12493 "cast to pointer from integer of different size".
12495 Improve doprnt and its use in verror. (Bug#8545)
12496 * doprnt.c (doprnt): Document the set of format control sequences
12497 supported by the function. Use SAFE_ALLOCA instead of always
12500 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12501 is one byte too soon. Don't use xrealloc; instead xfree and
12504 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12506 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12509 * gnutls.c: Renamed global_initialized to
12510 gnutls_global_initialized. Added internals for the
12511 :verify-hostname-error, :verify-error, and :verify-flags
12512 parameters of `gnutls-boot' and documented those parameters in the
12513 docstring. Start callback support.
12514 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12515 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12516 on error. Return error code.
12517 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12518 (emacs_gnutls_read): Likewise.
12519 (Fgnutls_boot): Return handshake error code.
12520 (emacs_gnutls_handle_error): New function.
12521 (wsaerror_to_errno): Likewise.

12558 to changes in oldXMenu/XMenu.h from 2011-04-16.
12559 (struct XMenu): Declare `help_text' `const char **'.

12576 changes in globals.h immediately force recompilation.
12577 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12578 $(CURDIR)/s/ms-w32.h.
12579 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

12583 <char-direction-table>: Deleted.
12585 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12587 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12588 * doprnt.c: Include limits.h.
12589 (SIZE_MAX): New macro.
12590 (doprnt): Return a size_t value. 2nd arg is now size_t.
12591 Many local variables are now size_t instead of int or unsigned.
12592 Improve overflow protection. Support `l' modifier for integer
12593 conversions. Support %l conversion. Don't assume an EMACS_INT
12594 argument for integer conversions and for %c.
12596 * lisp.h (doprnt): Restore prototype.
12598 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12599 $(SRC)/character.h.
12601 * Makefile.in (base_obj): Add back doprnt.o.
12603 * deps.mk (doprnt.o): Add back prerequisites.
12604 (callint.o): Depend on character.h.
12606 * eval.c (internal_lisp_condition_case): Include the handler
12607 representation in the error message.
12608 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12609 when breaking from the loop.
12611 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12613 * callint.c (Fcall_interactively): When displaying error message
12614 about invalid control letter, pass the character's codepoint, not
12615 a pointer to its multibyte form. Improve display of the character
12616 in octal and display also its hex code.
12618 * character.c (char_string): Use %x to display the (unsigned)
12619 codepoint of an invalid character, to avoid displaying a bogus
12622 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12623 `error', not SYMBOL_NAME itself.
12625 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12626 character arguments to `error'.
12628 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12629 to `error' in error message about FINAL_CHAR argument. Make sure
12630 FINAL_CHAR is a character, and use %c when it is passed as
12631 argument to `error'.
12633 2011-04-23 Eli Zaretskii <eliz@gnu.org>

12821 ns_descriptor_to_entity that were caused by using free to
12822 deallocate memory blocks that were allocated by xmalloc (via
12823 xstrdup). This caused Emacs to crash when compiled with

12843 (emacs_read, emacs_write): Use it.
12844 * process.c (send_process): Adjust to the new signatures of
12845 emacs_write and emacs_gnutls_write. Do not attempt to store

13175 * lisp.h: Remove these decls.
13177 * buffer.c (buffer_count): Remove unused var.
13179 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

13181 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13182 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13183 exported only to the debugger.
13185 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
13186 * atimer.h (run_all_atimers): Remove; not exported.
13188 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13189 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13190 was inaccessible from Lisp.
13191 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13192 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13194 alloc.c: Import and export fewer symbols, and remove unused items.
13195 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13197 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13198 it's not optimized away by whole-program optimization.
13199 (message_enable_multibyte, free_misc): Remove.
13200 (catchlist, handlerlist, mark_backtrace):
13201 Declare only if BYTE_MARK_STACK.

13210 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13211 (mark_backtrace): Define only if BYTE_MARK_STACK.
13212 * xdisp.c (message_enable_multibyte): Now static.
13214 Declare Lisp_Object Q* variables to be 'static' if not exported.
13215 This makes it easier for human readers (and static analyzers)
13216 to see whether these variables are used from other modules.
13217 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13218 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

13227 Remove decls of unexported vars.
13228 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13230 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13232 Make Emacs functions such as Fatom 'static' by default.
13233 This makes it easier for human readers (and static analyzers)
13234 to see whether these functions can be called from other modules.
13235 DEFUN now defines a static function. To make the function external
13236 so that it can be used in other C modules, use the new macro DEFUE.
13237 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13238 (Finit_image_library):
13239 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13240 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13241 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13242 Remove decls, since these functions are now static.
13243 (Funintern, Fget_internal_run_time): New decls, since these functions
13244 were already external.
13246 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

13254 Mark functions with DEFUE instead of DEFUN,
13255 if they are used in other modules.
13256 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13257 decls for now-static functions.
13258 * buffer.h (Fdelete_overlay): Remove decl.
13259 * callproc.c (Fgetenv_internal): Mark as internal.

13268 * image.c (Finit_image_library): New forward static decl.
13269 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13270 * intervals.h (Fprevious_property_change):
13271 (Fremove_list_of_text_properties): Remove decls.
13272 * keyboard.c (Fthis_command_keys): Remove decl.
13273 (Fcommand_execute): New forward static decl.

13289 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13291 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13294 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13296 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13297 when at ZV. (Bug#8487)
13299 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13301 * charset.c (Fclear_charset_maps): Use xfree instead of free.

13307 * xsettings.c (read_and_apply_settings): Likewise.
13309 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13310 (overrun_check_free): Protoize.
13312 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13314 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13315 since callers should never pass a negative size.
13316 Change the signature to match that of plain 'read' and 'write'; see
13317 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13318 * lisp.h: Update prototypes of emacs_write and emacs_read.
13320 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13322 * xdisp.c (redisplay_window): Don't try to determine the character
13323 position of the scroll margin if the window start point w->startp
13324 is outside the buffer's accessible region. (Bug#8468)
13326 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13328 Fix write-region and its subroutines for buffers > 2GB.
13329 * fileio.c (a_write, e_write): Modify declaration of arguments and
13330 local variables to support buffers larger than 2GB.
13331 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13333 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13334 argument, local variables, and return value.
13336 * lisp.h: Update prototypes of emacs_write and emacs_read.
13338 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13340 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13342 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13344 Fix more problems found by GCC 4.6.0's static checks.
13346 * xdisp.c (vmessage): Use a better test for character truncation.
13348 * charset.c (load_charset_map): <, not <=, for optimization,
13349 and to avoid potential problems with integer overflow.
13350 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13351 * casetab.c (set_identity, shuffle): Likewise.
13352 * editfns.c (Fformat): Likewise.
13353 * syntax.c (skip_chars): Likewise.
13355 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13356 This also lets GCC 4.6.0 generate slightly better loop code.
13358 * callint.c (Fcall_interactively): <, not <=, for optimization.
13359 (Fcall_interactively): Count the number of arguments produced,
13360 not the number of arguments given. This is simpler and lets GCC
13361 4.6.0 generate slightly better code.
13363 * ftfont.c: Distingish more carefully between FcChar8 and char.
13364 The previous code passed unsigned char * to a functions like
13365 strlen and xstrcasecmp that expect char *, which does not
13366 conform to the C standard.
13367 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13368 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13369 char * when the C standard requires it.
13371 * keyboard.c (read_char): Remove unused var.
13373 * eval.c: Port to Windows vsnprintf (Bug#8435).
13374 Include <limits.h>.
13375 (SIZE_MAX): Define if the headers do not.
13376 (verror): Do not give up if vsnprintf returns a negative count.
13377 Instead, grow the buffer. This ports to Windows vsnprintf, which
13378 does not conform to C99. Problem reported by Eli Zaretskii.
13379 Also, simplify the allocation scheme, by avoiding the need for
13380 calling realloc, and removing the ALLOCATED variable.
13382 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13384 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13385 But keep the doprint source code for now, as we might revamp it
13386 and use it again (Bug#8435).
13387 * lisp.h (doprnt): Remove.
13388 * Makefile.in (base_obj): Remove doprnt.o.
13389 * deps.mk (doprnt.o): Remove.
13391 error: Print 32- and 64-bit integers portably (Bug#8435).
13392 Without this change, on typical 64-bit hosts error ("...%d...", N)
13393 was used to print both 32- and 64-bit integers N, which relied on
13394 undefined behavior.
13395 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13396 * lisp.h (error, verror): Mark as printf-like functions.
13397 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13398 Report overflow in size calculations when allocating printf buffer.
13399 Do not truncate output string at its first null byte.
13400 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13401 Truncate the output at a character boundary, since vsnprintf does not
13403 * charset.c (check_iso_charset_parameter): Convert internal
13404 character to string before calling 'error', since %c now has the
13406 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13407 overflow when computing char to be passed to 'error'. Do not
13408 pass Lisp_Object to 'error'; pass the integer instead.
13409 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13410 formatted with plain %d.
13412 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13414 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13416 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13418 * xterm.c (x_catch_errors): Remove duplicate declaration.
13420 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13422 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13424 2011-04-10 Jim Meyering <meyering@redhat.com>
13426 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13427 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13428 return ssize_t not "int", and use size_t as the buffer length.
13429 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13430 * gnutls.h: Update declarations.
13431 * process.c (read_process_output): Use ssize_t, to match.
13432 (send_process): Likewise.
13434 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13436 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13438 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13440 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13441 Use unsigned char, to match FcChar8 type definition.
13443 * xterm.c (handle_one_xevent):
13444 * xmenu.c (create_and_show_popup_menu):
13445 * xselect.c (x_decline_selection_request)
13446 (x_reply_selection_request): Avoid type-punned deref of X events.
13448 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13450 Fix some uses of `int' instead of EMACS_INT.
13451 * search.c (string_match_1, fast_string_match)
13452 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13453 (scan_buffer, find_next_newline_no_quit)
13454 (find_before_next_newline, search_command, Freplace_match)
13455 (Fmatch_data): Make some `int' variables be EMACS_INT.
13457 * xdisp.c (display_count_lines): 3rd argument and return value now
13458 EMACS_INT. All callers changed.
13459 (pint2hrstr): Last argument is now EMACS_INT.
13461 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13462 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13463 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

13474 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13475 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13477 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13478 (encode_invocation_designation): Last argument P_NCHARS is now
13480 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13481 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13483 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13486 * ccl.c (Fccl_execute_on_string): Declare some variables
13489 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13491 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13493 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13495 * process.c (Fformat_network_address): Doc fix.
13497 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13499 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13501 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13503 * keyboard.c (read_char): Call Lisp function help-form-show,
13504 instead of using internal_with_output_to_temp_buffer.
13505 (Qhelp_form_show): New var.
13506 (syms_of_keyboard): Use DEFSYM macro.
13508 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13521 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13523 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13525 Fix more problems found by GCC 4.6.0's static checks.
13527 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13529 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13531 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13533 * xdisp.c (vmessage): Mark as a printf-like function.
13535 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

13539 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13540 printf-like functions.
13541 (tiff_load): Add casts to remove these marks before passing them
13542 to system-supplied API.
13544 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13546 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13547 This avoids several warnings with gcc -Wstrict-overflow.
13548 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13549 directly, rather than having caller test rule sign. This avoids
13550 some unnecessary tests.
13551 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13552 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13553 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13555 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13556 (xfont_open): Avoid unnecessary tests.
13558 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13560 * composite.h, composite.c (composition_gstring_put_cache):
13561 Use EMACS_INT, not int, for length.
13563 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13564 breaking out part of COMPOSITION_DECODE_RULE.
13565 (COMPOSITION_DECODE_RULE): Use it.
13566 * composite.c (get_composition_id): Remove unused local vars,
13567 by using the new macro.
13569 * textprop.c (set_text_properties_1): Change while to do-while,
13570 since the condition is always true at first.
13572 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13573 (interval_deletion_adjustment): Return unsigned value.
13576 * process.c (list_processes_1, create_pty, read_process_output):
13577 (exec_sentinel): Remove vars that were set but not used.
13578 (create_pty): Remove unnecessary "volatile"s.
13579 (Fnetwork_interface_info): Avoid possibility of int overflow.

13585 * syntax.c (scan_words): Remove var that was set but not used.
13586 (update_syntax_table): Use unsigned instead of int.
13588 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13589 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13590 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13592 * print.c (print_error_message): Avoid int overflow.
13594 * font.c (font_list_entities): Redo for clarity,
13595 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13597 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13598 (font_score): Avoid potential overflow in diff calculation.
13600 * fns.c (substring_both): Remove var that is set but not used.
13601 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13603 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13605 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13606 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13607 can always succeed if overflow has undefined behavior.
13609 * search.c (boyer_moore, wordify): Remove vars set but not used.
13610 (wordify): Omit three unnecessary tests.
13612 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13613 All callers changed. This avoids the need for an unused var.
13615 * casefiddle.c (casify_region): Remove var that is set but not used.
13617 * dired.c (file_name_completion): Remove var that is set but not used.
13619 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13621 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13622 (Finsert_file_contents): Remove unnecessary code checking fd.
13624 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13625 Check for integer overflow on size calculations.
13627 * buffer.c (Fprevious_overlay_change): Remove var that is set
13630 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13631 Remove vars that are set but not used.
13632 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13633 (timer_check_2): Mark vars as initialized.
13635 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13637 * image.c (lookup_image): Remove var that is set but not used.
13638 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13640 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13641 that are set but not used.
13643 * xfns.c (make_invisible_cursor): Don't return garbage
13644 if XCreateBitmapFromData fails (Bug#8410).
13646 * xselect.c (x_get_local_selection, x_handle_property_notify):
13647 Remove vars that are set but not used.
13649 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13650 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13652 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13653 Remove var that is set but not used.
13654 (scroll_bar_windows_size): Now size_t, not int.
13655 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13656 Check for overflow.
13658 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13659 (map_tty_color) [!defined MSDOS]: Likewise.
13661 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13663 * coding.c: Remove vars that are set but not used.
13664 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13665 All callers changed.
13666 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13667 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13668 (decode_coding_charset): Remove vars that are set but not used.
13670 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13671 that is set but not used.
13673 * print.c (print_object): Remove var that is set but not used.
13675 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13676 The gnulib version avoids calling malloc in the usual case,
13677 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13678 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13679 * filelock.c (current_lock_owner): Likewise.
13680 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13681 * sysdep.c: Include allocator.h, careadlinkat.h.
13682 (emacs_no_realloc_allocator): New static constant.
13683 (emacs_readlink): New function.
13684 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13685 ../lib/careadlinkat.h.
13687 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13689 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13690 first non-nil return value).
13692 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13694 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13695 if not defined (Bug#8403).
13697 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13699 * xdisp.c (display_count_lines): Remove parameter `start',
13700 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13701 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13702 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13704 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13705 and thereabouts. All callers changed.
13706 (get_per_char_metric): Remove parameter `f', unused since
13707 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13709 2011-04-02 Jim Meyering <meyering@redhat.com>
13711 do not dereference NULL upon failed strdup
13712 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13713 (ns_get_family): Likewise.
13715 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13717 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13719 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13721 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13724 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13726 Add lexical binding.
13728 * window.c (Ftemp_output_buffer_show): New fun.
13729 (Fsave_window_excursion):
13730 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13732 * lread.c (lisp_file_lexically_bound_p): New function.
13733 (Fload): Bind Qlexical_binding.
13734 (readevalloop): Remove `evalfun' arg.
13735 Bind Qinternal_interpreter_environment.
13736 (Feval_buffer): Bind Qlexical_binding.
13737 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13739 (syms_of_lread): Declare `lexical-binding'.
13741 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13743 * keyboard.c (eval_dyn): New fun.
13744 (menu_item_eval_property): Use it.
13746 * image.c (parse_image_spec): Use Ffunctionp.
13748 * fns.c (concat, mapcar1): Accept byte-code-functions.
13750 * eval.c (Fsetq): Handle lexical vars.
13751 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13752 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13753 (FletX, Flet): Obey lexical binding.
13754 (Fcommandp): Handle closures.
13755 (Feval): New `lexical' arg.
13756 (eval_sub): New function extracted from Feval. Use it almost
13757 everywhere where Feval was used. Look up vars in lexical env.
13759 (Ffunctionp): Move from subr.el.
13760 (Ffuncall): Handle closures.
13761 (apply_lambda): Remove `eval_flags'.
13762 (funcall_lambda): Handle closures and new byte-code-functions.
13763 (Fspecial_variable_p): New function.
13764 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13765 but without exporting it to Lisp.
13767 * doc.c (Fdocumentation, store_function_docstring):
13768 * data.c (Finteractive_form): Handle closures.
13770 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13773 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13775 (exec_byte_code): New function extracted from Fbyte_code to handle new
13776 calling convention for byte-code-functions. Add new byte-codes.
13778 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13780 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13782 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13784 * xdisp.c (redisplay_internal): Fix prototype.
13786 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13788 * xdisp.c (SCROLL_LIMIT): New macro.
13789 (try_scrolling): Use it when setting scroll_limit.
13790 Limit scrolling to 100 screen lines.
13791 (redisplay_window): Even when falling back on "recentering",
13792 position point in the window according to scroll-conservatively,
13793 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13795 (try_scrolling): When point is above the window, allow searching
13796 as far as scroll_max, or one screenful, to compute vertical
13797 distance from PT to the scroll margin position. This prevents
13798 try_scrolling from unnecessarily failing when
13799 scroll-conservatively is set to a value slightly larger than the
13800 window height. Clean up the case of PT below the margin at bottom
13801 of window: scroll_max can no longer be INT_MAX. When aggressive
13802 scrolling is in use, don't let point enter the opposite scroll
13803 margin as result of the scroll.
13804 (syms_of_xdisp) <scroll-conservatively>: Document the
13805 threshold of 100 lines for never-recentering scrolling.
13807 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13809 * dispextern.h (move_it_by_lines):
13810 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

13812 (message_log_check_duplicate): Remove parameters `prev_bol' and
13813 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13814 (redisplay_internal): Remove parameter `preserve_echo_area',
13815 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13817 * indent.c (Fvertical_motion):
13818 * window.c (window_scroll_pixel_based, Frecenter):
13819 Don't pass `need_y_p' to `move_it_by_lines'.
13821 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13823 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13824 steal a few bits to be more compact.
13825 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13826 Remove unneeded casts.
13828 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13830 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13832 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13833 binding" message (bug#7967).
13835 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13837 Fix more problems found by GCC 4.6.0's static checks.
13839 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13840 Remove unused local var.
13842 * editfns.c (Fmessage_box): Remove unused local var.
13844 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13845 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13846 Omit unused local vars.
13847 * window.c (shrink_windows): Omit unused local var.
13848 * menu.c (digest_single_submenu): Omit unused local var.
13849 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13850 Omit unused local var.
13852 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13853 Don't assume string length fits in int.
13854 (keyremap_step, read_key_sequence): Use size_t for sizes.
13855 (read_key_sequence): Don't check last_real_key_start redundantly.
13857 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13858 instead of alloca (Bug#8344).
13860 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13861 (Fbacktrace_frame): Don't assume nframes fits in int.
13863 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

13868 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13870 * cm.c (calccost): Turn while-do into do-while, for clarity.
13872 * keyboard.c (syms_of_keyboard): Use the same style as later
13873 in this function when indexing through an array. This also
13874 works around GCC bug 48267.
13876 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13878 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13880 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13881 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13883 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13884 This avoids undefined behavior on integer overflow, and is a bit
13885 more convenient anyway since it is compared to a size_t variable.
13887 Variadic C functions now count arguments with size_t, not int.
13888 This avoids an unnecessary limitation on 64-bit machines, which
13889 caused (substring ...) to crash on large vectors (Bug#8344).
13890 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13891 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13899 * fns.c (concat): Likewise.
13900 * frame.c (x_set_frame_parameters): Likewise.
13901 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13902 0 if not found, not -1. All callers changed.
13904 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13905 (stack_copy_size): Now size_t, not int.
13906 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13908 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13910 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13911 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13912 All callers changed.
13914 * lisp.h (multibyte_char_to_unibyte):
13915 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13916 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13922 * xdisp.c (message_dolog, set_message_1): All callers changed.
13924 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13926 * keyboard.c (safe_run_hook_funcall): New function.
13927 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13928 don't set the hook to nil, but remove the offending function instead.
13929 (Qcommand_hook_internal): Remove, unused.
13930 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13931 Vcommand_hook_internal.
13933 * eval.c (enum run_hooks_condition): Remove.
13934 (funcall_nil, funcall_not): New functions.
13935 (run_hook_with_args): Call each function through a `funcall' argument.
13936 Remove `cond' argument, now redundant.
13937 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13938 (Frun_hook_with_args_until_failure): Adjust accordingly.
13939 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

13945 * print.c (strout): Remove parameter `multibyte', unused since
13946 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13948 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13949 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13950 All callers changed.
13952 * w32.c (_wsa_errlist): Use braces for struct initializers.
13954 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13955 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13956 All callers changed.

14111 * buffer.c (Fkill_all_local_variables):
14112 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14114 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

14117 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14119 Fix more problems found by GCC 4.5.2's static checks.
14121 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14122 the first time through the loop, since we know p0 < p1 then.
14123 This also avoids a gcc -Wstrict-overflow warning.
14125 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14126 leading to a memory leak, possible in functions like
14127 load_charset_map_from_file that can allocate an unbounded number
14128 of objects (Bug#8318).
14130 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14131 that could (at least in theory) be that large.
14133 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14134 This is less likely to overflow, and avoids undefined behavior if
14135 overflow does occur. All callers changed. Use strtoul to scan
14136 for the unsigned long integer.
14137 (pint2hrstr): Simplify and tune code slightly.
14138 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14148 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14151 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14153 * process.c (Fmake_network_process): Use socklen_t, not int,
14154 where POSIX says socklen_t is required in portable programs.
14155 This fixes a porting bug on hosts like 64-bit HP-UX, where
14156 socklen_t is wider than int (Bug#8277).
14157 (Fmake_network_process, server_accept_connection):
14158 (wait_reading_process_output, read_process_output):
14161 * process.c: Rename or move locals to avoid shadowing.

14171 Make tparam.h and terminfo.c consistent.
14172 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14173 Include tparam.h instead, since it declares them.
14174 * cm.h (PC): Remove extern decl; tparam.h now does this.
14175 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14176 * terminfo.c: Include tparam.h, to check interfaces.
14177 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14178 (tparam): Adjust signature to match interface in tparam.h;
14179 this removes some undefined behavior. Check that outstring and len
14180 are zero, which they always are with Emacs.
14181 * tparam.h (PC, BC, UP): New extern decls.
14183 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14184 (xftfont_open): Rename locals to avoid shadowing.
14186 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

14198 * composite.c (composition_compute_stop_pos): Rename local to
14200 (composition_reseat_it): Remove unused locals.
14201 (find_automatic_composition, composition_adjust_point): Likewise.
14202 (composition_update_it): Mark var as initialized.
14203 (find_automatic_composition): Mark vars as initialized,
14204 with a FIXME (Bug#8290).

14208 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14209 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14210 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14211 to avoid shadowing.
14213 * textprop.c (property_change_between_p): Remove; unused.
14215 * intervals.c (interval_start_pos): Now static.
14217 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14223 Fix pointer signedness.
14224 (alsa_choose_format): Remove unused local var.
14225 (wav_play): Initialize a variable to 0, to prevent undefined
14226 behavior (Bug#8278).
14228 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14230 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14232 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14233 clobbering (Bug#8298).
14234 * sysdep.c (sys_subshell): Likewise.
14235 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14237 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14238 This should get cleaned up, so that child_setup has the
14239 same signature on all platforms.
14241 * callproc.c (call_process_cleanup): Now static.
14242 (relocate_fd): Rename locals to avoid shadowing.
14244 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14246 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14247 not to be necessary, and produces flickering.
14249 2011-03-20 Glenn Morris <rgm@gnu.org>
14251 * config.in: Remove file.
14253 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14255 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14256 are now in src/globals.h.
14257 (syms_of_minibuf): Remove spurious & from previous change.
14259 2011-03-20 Leo Liu <sdl.web@gmail.com>
14261 * minibuf.c (completing-read-function): New variable.
14262 (completing-read-default): Rename from completing-read.
14263 (completing-read): Call completing-read-function.

14267 * xfaces.c (Fx_load_color_file):
14268 Read color file from absolute filename (bug#8250).
14270 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14272 * makefile.w32-in: Update dependencies.
14274 2011-03-17 Eli Zaretskii <eliz@gnu.org>
14276 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

14283 (sigchld_handler): Now static.
14285 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14286 That way, the code declares only the vars that it needs.

14296 (CONSTANTLIM): Remove; unused.
14297 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14298 Define only if needed.
14300 * unexelf.c (unexec): Name an expression,
14301 to avoid gcc -Wbad-function-cast warning.
14302 Use a different way to cause a compilation error if anyone uses
14303 n rather than nn, a way that does not involve shadowing.
14304 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14306 * deps.mk (unexalpha.o): Remove; unused.
14308 New file unexec.h, the (simple) interface for unexec (Bug#8267).

14374 (Fformat_time_string, Fencode_time, Finsert_char):
14375 (Ftranslate_region_internal, Fformat):
14376 Rename or remove local vars to avoid shadowing.

14417 (uppercasep, lowercasep, upcase): New static inline functions.
14418 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14427 which gcc can warn about.
14428 (regex_compile, re_match_2_internal): Mark locals as initialized.
14429 (RETALLOC_IF): Define only if needed.
14430 (WORDCHAR_P): Likewise. This one is never needed, but is used
14431 only in a comment talking about a compiler bug, so put inside
14432 the #if 0 of that comment.
14433 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14434 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14462 gcpro1, gcpro2, etc.
14463 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14465 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14466 argument, for consistency with GCPRO2_VAR, etc: it is now the

14470 Rename locals to avoid shadowing.
14472 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

14476 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...

14478 and the new implementation with inline functions needs to have
14479 current_buffer in scope now, rather than later when the macros
14481 (downcase, upcase1): New static inline functions.
14482 (DOWNCASE, UPCASE1): Reimplement using these functions.
14483 This avoids undefined behavior in expressions like
14484 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14485 from race conditions in accessing the global variables
14486 case_temp1 and case_temp2.
14487 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

14511 * marker.c (bytepos_to_charpos): Remove; unused.
14513 * lisp.h (verify_bytepos, count_markers): New decls,
14514 so that gcc does not warn that these functions aren't declared.

14524 * buffer.c (fix_overlays_before): Mark locals as initialized.
14525 (fix_start_end_in_overlays): Likewise. This function should be
14526 simplified by using pointers-to-pointers, but that's a different

14530 (report_overlay_modification): Rename locals to avoid shadowing.

14535 to suppress a gcc -Wclobbered warning that does not seem to be right.
14536 (MAXPATHLEN): Define only if needed.
14538 * process.c (serial_open, serial_configure): Move decls from here ...
14539 * systty.h: ... to here, so that they can be checked.
14541 * fns.c (get_random, seed_random): Move extern decls from here ...
14542 * lisp.h: ... to here, so that they can be checked.
14544 * sysdep.c (reset_io): Now static.
