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

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

139 Now constants, not macros.
141 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
143 Remove unnecessary casts involving pointers.
144 These casts are no longer needed now that we assume C89 or later,

146 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
147 (make_pure_float, make_pure_vector):

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

186 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
187 (map_w32_filename): Improve commentary. Simplify switch.
188 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
189 headers (most versions of MinGW w32api don't).
190 (get_security_info, create_symbolic_link)
191 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
193 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
194 in the argument file name.

196 GetFileAttributes fails with network-related error codes.
197 (sys_rename): Diagnose renaming of a symlink when the user doesn't
198 have the required privileges.
199 (get_file_security_desc_by_name): Renamed from
200 get_file_security_desc.
201 (stat_worker): New function, with most of the guts of 'stat', and
202 with addition of handling of symlinks and support for 'lstat'. If
203 possible, get file's attributes and security information by
204 handle, not by name. Produce S_IFLNK bit for symlinks, when
206 (stat, lstat): New functions, call 'stat_worker'.
207 (symlink, readlink, careadlinkat): Rewritten to create and resolve
208 symlinks when the underlying filesystem supports them.
210 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
212 Fix macroexp crash on Windows with debugging (Bug#12118).
213 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
214 checking subscripts; problem introduced with the recent
215 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
216 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
217 since it's used in non-static inline functions now.
219 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
220 Don't assume buffer size fits in 'int'. Remove unused local.
222 Use C99-style 'extern inline' if available.
223 * buffer.h (BUFFER_INLINE):
224 * category.h (CATEGORY_INLINE):
225 * character.h (CHARACTER_INLINE):

240 * composite.c (COMPOSITE_INLINE):
241 * dispnew.c (DISPEXTERN_INLINE):
242 * sysdep.c (SYSTIME_INLINE):
243 Define to EXTERN_INLINE, so that the corresponding functions
244 are compiled into code.
245 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
246 (INLINE_HEADER_END): New macros.
247 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

269 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
271 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
272 This how ASET and AREF are supposed to work, and makes
273 it easier to think about future improvements. See
274 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
275 * charset.h (set_charset_attr): New function.

526 2012-07-30 Glenn Morris <rgm@gnu.org>
528 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
529 does that unconditionally. Remove file, which is now empty.
531 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
534 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

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

685 2012-07-27 Eli Zaretskii <eliz@gnu.org>
687 * alloc.c (listn): Fix the order the arguments are consed onto the
690 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
691 enumeration constants, as PURE and HEAP are too general, and clash
692 with other headers and sources, such as gmalloc.c and the
693 MS-Windows system headers. All users changed.
695 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
697 Revert last save_excursion_save and save_excursion_restore changes.
698 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

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

713 complains about the types in the unevaluated arm when the argument
714 is an integer literal.
715 (xgetint): Simplify expression.
716 * alloc.c (gdb_make_enums_visible): New constant. This ports to
717 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
718 Zaretskii in <http://bugs.gnu.org/12036#13>.
719 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
720 needed now that we have gdb_make_enums_visible.
721 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)

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

779 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
780 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
781 not be usable in #if. This simplifies things.
783 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
785 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
787 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

790 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
791 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
792 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
793 Adjust to changes in lisp.h and emacs.c, by using
794 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
795 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
796 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
797 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
798 instead of gdb_valbits.
799 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
800 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
801 instead of gdb_array_mark_flag.
802 (xboolvector): Get size from $->size, not $->header.size.
803 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
804 (xreload, hook-run, hookpost-run): Remove.
805 * emacs.c: Include <verify.h>.
806 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
807 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
809 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
810 (gdb_USE_LSB_TAG): New enum constants.
811 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
812 Also define these as enum constants, so they're visible to GDB.

814 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
815 as constants, so they're visible to GDB.
816 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
817 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
818 Now enum constants, not macros, so they're visible to GDB.
819 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
820 more convenient now. All uses changed.
821 (VALMASK) [USE_LSB_TAG]: Also define in this case.

832 add argument, tune behavior, and adjust all callers.
834 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
836 Use typedef for EMACS_INT, EMACS_UINT.
837 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
838 than macros. This simplifies debugging in the usual case, since
839 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
840 and it allows expressions involving EMACS_INT casts.
841 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
843 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
845 * nsterm.m (ns_read_socket): Return early if there is a modal

855 Adjust buffer text indirection counters at the end of Fkill_buffer.
856 * buffer.c (Fkill_buffer): Adjust indirection counters when the
857 buffer is definitely dead. This should really fix an issue reported
858 by Christoph Scholtes again. (Bug#12007).
859 (init_buffer_once): Initialize indirection counters of
860 buffer_defaults and buffer_local_symbols (for sanity and safety).
862 2012-07-24 Eli Zaretskii <eliz@gnu.org>
864 * xdisp.c (init_iterator): Don't compute dimensions of truncation
865 and continuation glyphs on tooltip frames, leave them at zero.
866 Avoids continued lines in tooltips. (Bug#11832)
868 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
870 Simplify copy_overlay.
871 * buffer.c (copy_overlay): Simplify. Use build_marker.

877 or invalid. (Bug#12025)
879 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
880 it signals an error when a tooltip frame is being created.
882 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

895 Swap buffer text indirection counters in Fbuffer_swap_text.
896 * buffer.c (Fbuffer_swap_text): Swap indirections too.
897 This avoids crash reported by Christoph Scholtes at
898 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
900 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
902 * nsmenu.m (Popdown_data): New struct.
903 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
905 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
906 (initWithContentRect): Make imgView and contentView non-static
907 and autorelease them. Also autorelease img and matrix (Bug#12005).
908 (dealloc): Remove (Bug#12005).

1656 * s/aix4-2.h (unix): Remove; no longer needed.
1658 EMACS_TIME simplification (Bug#11875).
1659 This replaces macros (which typically do not work in GDB)

1661 The functional style also makes code easier to read and maintain.
1662 * systime.h: Include <sys/time.h> on all hosts, not just if
1663 WINDOWSNT, since 'struct timeval' is needed in general.

1676 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1677 not functions. All uses rewritten to use the following, respectively:

1679 (add_emacs_time, sub_emacs_time): New functions.
1680 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1698 (menu_separator_name_p):

1701 * nsterm.m: Include <ftoastr.h>.
1703 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1704 Prefer snprintf to strncpy.
1705 * nsterm.m (ns_term_init):
1706 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1707 * nsterm.m (ns_term_init):
1708 Avoid the need for strncpy, by using build_string or
1709 make_unibyte_string directly. Use dtoastr, not snprintf.
1710 * process.c (Fmake_network_process): Diagnose service names that
1711 are too long, rather than silently truncating them or creating
1712 non-null-terminated names.
1713 (Fnetwork_interface_info): Likewise, for interface names.
1714 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1715 Prefer sprintf to strncat.

1722 Clarify fallback case.
1724 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

1729 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1730 where argument type is known to be a Lisp_Cons.

1747 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1748 argument, adjust users accordingly. Use build_pure_c_string where

1785 O_RDONLY already includes it).
1787 Stop ns builds setting the EMACSLOADPATH environment variable.
1788 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1789 Now it does not set EMACSLOADPATH, just returns the load-path string.
1790 * nsterm.h: Update accordingly.
1791 * lread.c [HAVE_NS]: Include nsterm.h.
1792 (init_lread) [HAVE_NS]: Use ns_load_path.

1802 (ns_init_paths): Do not set EMACSPATH.
1803 * nsterm.h (ns_exec_path): Add it.

1829 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1830 where int is good enough, as vsprintf returns an int.
1831 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1833 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1835 Use make_formatted_string to avoid double length calculation.
1836 * lisp.h (make_formatted_string): New prototype.
1837 * alloc.c (make_formatted_string): New function.
1838 * buffer.c (Fgenerate_new_buffer_name): Use it.
1839 * dbus.c (syms_of_dbusbind): Likewise.
1840 * editfns.c (Fcurrent_time_zone): Likewise.
1841 * filelock.c (get_boot_time): Likewise.
1842 * frame.c (make_terminal_frame, set_term_frame_name)
1843 (x_report_frame_params): Likewise.
1844 * image.c (gs_load): Likewise.
1845 * minibuf.c (get_minibuffer): Likewise.

1856 * nsterm.h (ns_etc_directory): Add it.
1857 * callproc.c [HAVE_NS]: Include nsterm.h.
1858 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1860 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1862 Move marker debugging code under MARKER_DEBUG.
1863 * marker.c (MARKER_DEBUG): Move marker debugging code under
1864 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1865 for bootstrap with --enable-checking (~3x slowdown reported
1866 by Juanma Barranquero <lekktu@gmail.com>).
1867 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1869 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1871 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1872 See <http://bugs.gnu.org/11825#29>.
1874 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1876 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1877 has no font, use the frame's font. (Bug#11813)
1878 (display_line): Add commentary about displaying truncation glyphs
1880 (produce_special_glyphs): Move here from term.c.
1882 * term.c (produce_special_glyphs): Move to xdisp.c.
1884 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1887 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1889 * xdisp.c (display_line): Avoid warning about implicit declaration
1892 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1894 * lisp.h: Remove empty conditional.
1896 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1898 * lread.c (load_path_check): Now static.
1900 Fix some minor --with-ns problems found by static checking.
1901 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1902 (x_set_font) [!HAVE_X_WINDOWS]:
1903 * image.c (xpm_load_image) [HAVE_NS]:
1904 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1905 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1906 Remove unused local.
1907 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1908 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1909 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1910 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1911 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1912 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1913 Fix pointer signedness problem.
1914 * xfaces.c (FRAME_X_FONT_TABLE):
1915 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1917 2012-07-07 Glenn Morris <rgm@gnu.org>
1919 * lread.c (load_path_check): New function, split from init_lread.
1920 (init_lread): Reorganize. Motivation:
1921 If EMACSLOADPATH is set, check/warn about that rather than the
1922 defaults, which we are not going to use. Hence we can remove
1923 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1924 Don't warn if site-lisp directories are missing.
1925 If not installed, start from a blank load-path, since
1926 PATH_LOADSEARCH refers to the eventual installation directories.
1928 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1930 Support truncation and continuation glyphs on GUI frames, when
1931 fringes are disabled. (Bug#11832)
1932 * xdisp.c (init_iterator): Get dimensions of truncation and
1933 continuation glyphs even if on GUI frames. Adjust
1934 it->last_visible_x on GUI frames when the left or right fringes,
1935 or both, are absent.
1936 (start_display, move_it_in_display_line_to): Handle the case of a
1937 GUI frame without a fringe to display continuation or truncation
1939 (insert_left_trunc_glyphs): Support GUI frames: make sure
1940 truncation glyphs overwrite enough glyphs from the current line to
1941 have sufficient space in pixels.
1942 (display_line): Support truncation and continuation glyphs on GUI
1943 frames. If some spare pixels are left on the line after inserting
1944 the truncation glyphs, fill that space with a stretch glyph of a
1945 suitably computed width.
1947 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1948 produce_glyphs, to support GUI sessions.
1950 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1952 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1954 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1956 Do not require float-time's arg to fit in time_t (Bug#11825).
1957 This works better on hosts where time_t is unsigned, and where
1958 float-time is applied to the (negative) difference between two times.
1959 * editfns.c (decode_time_components): Last arg is now double *,
1960 not int *, and means to store all the result as a double, without
1961 worrying about whether the seconds part fits in time_t.
1962 All callers changed.
1963 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1964 All callers changed.
1965 (Ffloat_time): Do not fail merely because the specified time falls
1966 outside of time_t range.
1968 2012-07-07 Glenn Morris <rgm@gnu.org>
1970 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1971 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

1974 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1976 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1977 Update dependencies.
1979 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1981 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1983 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1984 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1985 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1986 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1987 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1988 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1990 * xfont.c (compare_font_names): Redo to omit the need for casts.
1992 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1994 * xfns.c (Fx_change_window_property): Doc fix.
1995 * w32fns.c (Fx_change_window_property): Doc fix.
1997 * w32fns.c (Fx_window_property): Accept the same arguments as the
1998 X Windows version. Doc fix.
1999 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2001 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2002 Eli Zaretskii <eliz@gnu.org>
2004 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2005 Windows-specific code from nt/config.nt moved here.
2006 Obsolete settings removed.
2008 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2010 * process.c: Avoid unnecessary calls to gettime.
2011 (wait_reading_process_output): Don't get the time of day
2012 when gobbling data immediately and not waiting, as there's no need
2013 for it in that case. This removes a FIXME.
2015 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2017 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2018 is defined (Bug#11768).
2020 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2022 Fix marker debugging code.
2023 * marker.c (byte_char_debug_check): Do not perform the check
2024 if buffer is not multibyte.
2025 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2026 Call byte_char_debug_check with correct arguments.
2028 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2030 Compile marker debugging code only if ENABLE_CHECKING is defined.
2031 * marker.c (byte_char_debug_check, count_markers):
2032 Use only if ENABLE_CHECKING is defined.
2033 (byte_debug_flag): Remove.
2034 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2035 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2037 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2039 Avoid code repetition in marker-related functions.
2040 * marker.c (attach_marker): New function.
2041 (Fset_marker, set_marker_restricted, set_marker_both)
2042 (set_marker_restricted_both): Use it.
2043 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2044 Consistently rename charno to charpos.
2045 (marker_position): Add eassert.
2046 (marker_byte_position): Convert to eassert.

2061 * editfns.c (buildmark): Remove.
2062 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2063 (save_restriction_save): Use build_marker.
2064 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2065 * window.c (save_window_save): Likewise.
2067 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2069 Do not use Fdelete_overlay in delete_all_overlays
2070 to avoid redundant calls to unchain_overlay.
2071 * buffer.c (drop_overlay): New function.
2072 (delete_all_overlays, Fdelete_overlay): Use it.
2073 * minibuf.c (get_minibuffer): Fix comment.
2075 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2077 Port to OpenBSD 5.1 amd64.
2078 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2079 This is needed for OpenBSD, and should be harmless on all BSD systems.
2080 Also, include <sys/sysctl.h>, as it should be available on all
2081 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2082 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2083 use p_pid member, not kp_proc.pid.
2085 2012-07-06 Glenn Morris <rgm@gnu.org>
2087 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2089 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2091 More xmalloc and related cleanup.
2092 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2093 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2100 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2102 Omit needless casts involving void * pointers and allocation.
2103 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2104 as the former is more robust if P's type is changed.
2105 Prefer xzalloc to xmalloc + memset 0.
2106 Simplify malloc-or-realloc to realloc.
2107 Don't worry about xmalloc returning a null pointer.
2108 Prefer xstrdup to xmalloc + strcpy.
2109 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2111 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2112 alloca of a constant.
2114 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2116 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2117 hscroll is larger than the line width. Fixes long and futile
2118 looping inside extend_face_to_end_of_line (on a TTY) producing
2119 glyphs that are not needed and thrown away.
2121 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2123 * marker.c (set_marker_restricted_both): Simplify by using
2126 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2138 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2139 (update_theme_scrollbar_width, xg_create_scroll_bar):
2140 Use gtk_scrollbar_new (Bug#11768).

2142 (is_box_type): New function (Bug#11768).
2143 (xg_tool_item_stale_p): Call is_box_type.
2144 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2145 with default display (Bug#11768).
2147 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2149 * xdisp.c (window_hscroll_limited): New function.
2150 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2151 coordinates when window's hscroll is set to insanely large
2154 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2156 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2157 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

2223 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2224 This should be fixed in a better way; see Eli Zaretskii in
2225 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2226 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2228 * fileio.c (time_error_value): Rename from special_mtime.
2229 The old name's problems were noted by Eli Zaretskii in
2230 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2232 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2233 This variable's comment says Emacs needs at least one GDB-visible
2234 symbol of type enum pvec_type, to work around GDB problems.
2235 The symbol's value doesn't matter.
2237 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2238 that causes compilation to fail on pre-C99 compilers.
2240 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

2265 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2266 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2267 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2268 abusing vector->header.next.nbytes.
2269 (live_vector_p): Use PVEC_TYPE.
2270 (mark_object): Adapt code to extract pvectype. Use switch.
2272 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2274 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2275 Tighten new eassert a bit.
2277 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2279 Fix compilation with --enable-gcc-warnings and -O1
2281 * doprnt.c (doprnt): Change type of tem to int, initialize
2282 to avoid compiler warning. Add eassert.
2283 * search.c (simple_search): Initialize match_byte to avoid
2284 compiler warning. Add eassert.

2288 Avoid weird behavior with large horizontal scrolls.
2289 Without this change, for example, large hscroll values would
2290 mess up Emacs's display on Fedora 15 x86, presumably due to
2291 overflows in int calculations in the display code.
2292 Also, if buffers had long lines, Emacs would freeze.
2293 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2294 (set_window_hscroll): New function, containing the old guts of
2295 Fset_window_hscroll. Return the clipped value.
2296 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2297 This avoids the need to check against PTRDIFF_MAX.
2299 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2301 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2303 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2305 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2307 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2308 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2309 since GCC 4.4.6 issues a bogus warning for them.
2311 Fix bugs in file timestamp newness comparisons.
2312 * fileio.c (Ffile_newer_than_file_p):
2313 * lread.c (Fload): Use full timestamp resolution of files,
2314 not just the 1-second resolution, so that files that are only
2315 slightly newer still count as newer.
2316 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2317 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2319 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2321 * fileio.c: Improve handling of file time marker. (Bug#11852)
2322 (special_mtime): New function.
2323 (Finsert_file_contents, Fverify_visited_file_modtime):
2324 Use it to set special mtime values consistently.
2326 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2328 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2329 marker for non-existing file. (Bug#11852)
2331 2012-07-03 Glenn Morris <rgm@gnu.org>
2333 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2334 and did not make it into globals.h).
2336 2012-07-03 Tom Tromey <tromey@redhat.com>
2338 * window.c (Fset_window_margins, Fset_window_fringes)
2339 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2340 * textprop.c (Fprevious_property_change): No longer static.
2341 * syntax.c (Fsyntax_table_p): No longer static.
2342 * process.c (Fget_process, Fprocess_datagram_address): No longer

2352 * doc.c (Fdocumentation_property, Fsnarf_documentation):
2354 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
2356 * dired.c (Ffile_attributes): No longer static.
2357 * composite.c (Fcomposition_get_gstring): No longer static.
2358 * callproc.c (Fgetenv_internal): No longer static.
2360 * ccl.h: Remove EXFUNs.
2361 * buffer.h: Remove EXFUNs.
2362 * dispextern.h: Remove EXFUNs.
2363 * intervals.h: Remove EXFUNs.
2364 * fontset.h: Remove EXFUN.
2365 * font.h: Remove EXFUNs.
2366 * dosfns.c (system_process_attributes): Remove EXFUN.
2367 * keymap.h: Remove EXFUNs.
2368 * lisp.h: Remove EXFUNs.
2369 * w32term.h: Remove EXFUNs.
2370 * window.h: Remove EXFUNs.
2371 * xsettings.h: Remove EXFUN.
2372 * xterm.h: Remove EXFUN.
2374 2012-07-03 Glenn Morris <rgm@gnu.org>
2376 * lisp.h (Frandom): Make it visible to C.
2377 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2378 buffer for invisible buffers. (Bug#1229)
2380 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2382 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2383 values which aren't power of 2.
2384 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2385 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2388 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2390 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2392 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2394 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2396 * alloc.c (allocate_vector_block): Remove redundant
2397 calls to mallopt if DOUG_LEA_MALLOC is defined.
2398 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2399 avoid calls to mallopt if zero_vector is returned.
2401 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2403 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2404 is enabled, avoid dereferencing NULL current_sblock if
2407 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2409 Cleanup basic buffer management.
2410 * buffer.h (struct buffer): Change layout to use generic vector
2411 marking code. Fix some comments. Change type of 'clip_changed'
2412 to bitfield. Remove unused #ifndef old.
2413 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2414 (GET_OVERLAYS_AT): Fix indentation.
2415 (for_each_per_buffer_object_at): New macro.
2416 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2417 (Fbuffer_local_variables): Use it.
2418 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2419 * alloc.c (allocate_buffer): Adjust to match new layout of
2420 struct buffer. Fix comment.
2421 (mark_overlay): New function.
2422 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2423 Lisp area of struct buffer.
2424 (mark_object): Use it. Adjust marking of misc objects
2425 and related comments.
2427 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2429 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2430 wrapper that is not needed because the wrapped code is a no-op (zero
2431 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2432 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2434 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2436 * alloc.c (mark_buffer): Simplify. Remove prototype.
2437 (mark_object): Add comment. Reorganize marking of vector-like
2438 objects. Use CHECK_LIVE for all vector-like objects except buffers
2439 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2440 redundant calls to mark_vectorlike for bool vectors.
2442 2012-06-30 Glenn Morris <rgm@gnu.org>
2444 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2446 * epaths.in (PATH_SITELOADSEARCH): New.
2447 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2448 This is rather than relying on --enable-locallisppath elements
2449 having "site-lisp" in their names. (Bug#10208#25, 11658)
2451 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2453 * w32proc.c (sys_select): Accept and ignore one more argument.
2455 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2457 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2458 (pselect) [!MS_DOS]: Redirect to sys_select.
2460 * sysdep.c: Don't include dos.h and dosfns.h.
2462 * process.c (sys_select):
2463 * msdos.c (sys_select): Accept one more argument and ignore it.
2465 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2466 adapt data types and code to that.
2469 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2470 which clashes with the gnulib function of the same name.
2472 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2474 * font.c (font_style_to_value, font_style_symbolic)
2475 (font_prop_validate_style): Add type checks for values in
2478 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2480 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2483 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2485 * xdisp.c (try_window_id): Undo last change.
2487 * w32.c (getwd): Adjust commentary about startup_dir.
2488 (init_environment): Always call sys_access, even in non-MSVC
2489 builds. Don't chdir to the directory of the Emacs executable.
2490 This undoes code from 1997 which was justified by the need to
2491 "avoid conflicts when removing and renaming directories". But its
2492 downside was that every relative file name was being interpreted
2493 relative to the directory of the Emacs executable, which can never
2494 be TRT. In particular, it broke sys_access when called with
2495 relative file names.
2496 (sys_access): Map GetLastError to errno.
2498 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2500 * window.h (struct window): Change type of 'fringes_outside_margins'
2501 to bitfield. Fix comment. Adjust users accordingly.

2504 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2507 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2509 * gnutls.c (emacs_gnutls_handshake):
2510 Add QUIT to make the loop interruptible.
2512 2012-06-29 Glenn Morris <rgm@gnu.org>
2514 * charset.c (init_charset): Make lack of etc/charsets fatal.
2516 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2518 * editfns.c (region_limit): Fix type mismatch.
2520 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2522 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2523 undefined. Convert from xassert to eassert.
2524 * nsmenu.m: Convert from xassert to eassert.
2525 * nsterm.m: Likewise.
2527 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2529 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2531 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2533 Avoid integer overflow on scroll-left and scroll-right.
2534 * window.c (HSCROLL_MAX): New macro.
2535 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2536 overflow when requested scroll falls outside ptrdiff_t range.
2538 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2540 * window.h (struct window): Change type of 'hscroll',
2541 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2542 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2543 Adjust users accordingly.
2544 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2545 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2546 from EMACS_INT to ptrdiff_t.
2547 (make_window): Omit redundant initialization.
2549 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2553 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

2622 * alloc.c (allocate_string): Omit intervals initialization.
2623 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2624 as in make_pure_string and make_pure_c_string.

2682 a better opportunity to optimize away calls to strlen when the
2683 function is called with compile-time constant argument.
2684 * image.c (imagemagick_error): Convert to build_string.
2685 * w32proc.c (sys_spawnve): Likewise.
2686 * xterm.c (x_term_init): Likewise.
2688 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2690 Use sprintf return value instead of invoking strlen on result.
2691 In the old days this wasn't portable, since some sprintf
2692 implementations returned char *. But they died out years ago and
2693 Emacs already assumes sprintf returns int.
2694 Similarly for float_to_string.
2695 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2696 * ccl.c (ccl_driver):

2702 * xfns.c (syms_of_xfns):
2703 Use sprintf or float_to_string result to avoid need to call strlen.
2704 * data.c (Fnumber_to_string):
2705 Use make_unibyte_string, since the string must be ASCII.
2706 * lisp.h, print.c (float_to_string): Now returns int length.
2707 * term.c (produce_glyphless_glyph):
2708 Use sprintf result rather than recomputing it.
2710 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2711 * Makefile.in (ALL_CFLAGS):

2743 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2748 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2749 instead of truncating it to 63 (admittedly a generous limit).
2751 * process.c: Fix spelling and caps in comments.
2753 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

2879 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2881 Support higher-resolution time stamps (Bug#9000).
2882 The time stamps are only nanosecond-resolution at the C level,
2883 since that's the best that any real-world system supports now.
2884 But they are picosecond-resolution at the Lisp level, as that's
2885 easy, and leaves room for future OS improvements.
2887 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2890 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2891 Don't get current time unless it's needed.
2893 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2894 now provides it if it's absent.
2895 (start_atimer): Port to higher-res time stamps.
2896 Check for time stamp overflow. Don't get current time more
2897 often than is needed.
2899 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2900 Include systime.h, not time.h.
2901 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

2907 (struct image): Timestamp now has higher resolution.
2909 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2910 has at least microseconds now. All uses removed.
2911 (update_frame, update_single_window, update_window, update_frame_1)
2912 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2914 * editfns.c (time_overflow): Now extern.
2915 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2921 (make_time): Now static.
2922 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2923 Report an error if the time is invalid, rather than having the caller
2926 * fileio.c: Include <stat-time.h>
2927 (Fcopy_file): Copy higher-resolution time stamps.
2928 Prefer to set the time stamp via a file descriptor if that works.

2930 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2931 (Fvisited_file_modtime, Fset_visited_file_modtime):
2932 Support higher-resolution time stamps.
2934 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2936 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2938 * image.c (prepare_image_for_display, clear_image_cache)
2939 (lookup_image): Port to higer-resolution time stamps.
2941 * keyboard.c (start_polling, bind_polling_period):
2942 Check for time stamp overflow.
2943 (read_char, kbd_buffer_get_event, timer_start_idle)
2944 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2945 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2946 Port to higher-resolution time stamps. Do not assume time_t is signed.
2947 (decode_timer): New function. Timers are now vectors of length 9,
2948 not 8, to accommodate the picosecond component.
2949 (timer_check_2): Use it.
2951 * nsterm.m (select_timeout, timeval_subtract): Remove.
2952 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2953 as they're a bit more accurate and handle overflow better.
2954 (ns_select): Change prototype to be compatible with pselect.
2955 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2956 * nsterm.h (ns_select): Adjust prototype.
2958 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2959 us-resolution time stamps.
2960 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2962 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2964 * lisp.h (time_overflow): New decl.
2965 (wait_reading_process_output): First arg is now intmax_t, not int,
2966 to accommodate larger waits.
2968 * process.h (struct Lisp_Process.read_output_delay):
2969 Now counts nanoseconds, not microseconds.
2970 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2972 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2973 (wait_reading_process_output):
2974 Port to ns-resolution time stamps.
2975 (Faccept_process_output, wait_reading_process_output):
2976 Check for time stamp overflow. Do not assume time_t is signed.
2977 (select_wrapper): Remove; we now use pselect.
2978 (Fprocess_attributes): Now generates ns-resolution time stamps.
2980 * sysdep.c: Include utimens.h. Don't include utime.h
2981 or worry about struct utimbuf; gnulib does that for us now.
2982 (gettimeofday): Remove; gnulib provides a substitute.
2983 (make_timeval): New function.
2984 (set_file_times): Now sets ns-resolution time stamps.
2985 New arg FD; all uses changed.
2986 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2987 (system_process_attributes):
2988 Now returns ns-resolution time stamp. All uses changed.
2989 Check for time stamp overflow.
2991 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2992 provides a substitute now.
2994 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2995 since it guarantees struct timespec.
2996 (EMACS_TIME): Now struct timespec, so that we can support
2997 ns-resolution time stamps.
2998 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2999 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3000 (EMACS_USECS): Remove.
3001 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3002 so multiply the arg by 1000 before storing it.
3003 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3005 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3006 Port to ns-resolution time stamps.
3007 (EMACS_TIME_NEG_P): Remove; replaced by....
3008 (EMACS_TIME_SIGN): New macro.

3010 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3011 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3012 (make_timeval, make_lisp_time, decode_time_components): New decls.
3013 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3014 that it mishandled time_t overflow. You can't compare by subtracting!
3015 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3016 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3018 * term.c: Include <sys/time.h>.

3027 (w32_get_internal_run_time):
3028 Port to higher-resolution Emacs time stamps.
3029 (ltime): Now accepts single 64-bit integer, as that's more convenient
3032 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3034 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3035 for compatibility with pselect. Support ns-resolution time stamps.
3037 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3039 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3040 Check for time stamp overflow, and support ns-resolution time stamps.
3042 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3043 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3044 (timeval_subtract): Remove; no longer needed.
3045 (XTflash, XTring_bell, x_wait_for_event):
3046 Port to ns-resolution time stamps. Don't assume time_t is signed.
3048 2012-06-22 Chong Yidong <cyd@gnu.org>

3052 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3054 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3055 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3056 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3057 staticidx goes up to 1597 out of 1600 = 0x640.)
3059 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3061 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3062 Otherwise, the umask might be mistakenly 0 while handling input signals.

3084 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3086 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3087 since tty frames can be explicitly named.

3107 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3108 gets killed during executing of this function (Bug#11665).
3109 Try to always return Qt when the buffer has been actually killed.
3110 (Vkill_buffer_query_functions): In doc-string say that functions
3111 run by this hook should not change the current buffer.
3113 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3115 Fix recently-introduced process.c problems found by static checking.

3133 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3135 * lisp.h (eassert): Assume C89 or later.
3136 This removes the need for CHECK.
3137 (CHECK): Remove. Its comments about always evaluating its
3138 argument were confusing, as 'eassert' typically does not evaluate
3141 * coding.c (produce_chars): Use ptrdiff_t, not int.
3143 * xterm.c (x_draw_underwave): Check for integer overflow.
3144 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3296 * frame.c (delete_frame): Remove outdated comment.
3297 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
3298 USE_LISP_UNION_TYPE.

3322 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
3323 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
3324 * lisp.h (USE_LSB_TAG): Allow the builder to compile with

3326 USE_LSB_TAG now is always defined to be either 0 or 1.
3328 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3329 code works fine either way, and efficiency is not a concern here,
3330 as the union type is for debugging, not for production.
3331 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3332 Use an inline function on all platforms when using the union type,
3333 since this is simpler and 'static inline' can be used portably
3335 (LISP_INITIALLY_ZERO): New macro.
3336 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3337 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3406 dbus_type_is_basic if available.
3407 (xd_extract_signed, xd_extract_unsigned): Rename from
3408 extract_signed and extract_unsigned, respectively. Adapt callers.

3440 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3442 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3444 * alloc.c (allocate_vectorlike): Fix last change.

3475 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3477 * doprnt.c (doprnt): Truncate multibyte char correctly.
3478 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3479 would mishandle a string argument "Xc" if X was a multibyte
3480 character of length 2: it would truncate after X's first byte
3481 rather than including all of X.
3483 2012-06-06 Chong Yidong <cyd@gnu.org>
3485 * buffer.c (word_wrap): Doc fix.

3538 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3540 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3543 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3545 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3547 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3549 For a 'struct window', replace some Lisp_Object fields to
3550 bitfields where appropriate, remove unused fields.
3551 * window.h (struct window): Remove unused 'last_mark_x' and
3552 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3553 change it's type from Lisp_Object to bitfield.
3554 Change type of 'force_start', 'optional_new_start',
3555 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3556 fields from Lisp_Object to bitfield. Adjust users accordingly.
3558 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3560 Pacify gcc -Wdouble-precision when using Xaw.

3562 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3563 Use 'float' consistently, rather than 'float' in most places
3564 and 'double' in a couple of places.
3566 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3568 * xdisp.c (handle_stop): Detect whether we have overlay strings
3569 loaded by testing it->current.overlay_string_index to be
3570 non-negative, instead of checking whether n_overlay_strings is
3571 positive. (Bug#11587)
3573 2012-05-31 Chong Yidong <cyd@gnu.org>
3575 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

3581 * search.c (search_buffer): Remove calls to
3582 r_alloc_inhibit_buffer_relocation, as it is now called by
3583 maybe_unify_char, which was the cause of relocation of buffer text
3586 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3588 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3589 for the duration of call to load_charset, to avoid problems with
3590 callers of maybe_unify_char that access buffer text through C
3593 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3594 decrement the inhibition flag, instead of just setting or
3597 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3599 Remove obsolete '#define static' cruft.
3600 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3601 This #undef was "temporary" in 2000; it is no longer needed

3603 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3604 (gray_bitmap_bits): Remove; no longer needed.
3605 All uses replaced with definiens.

3617 (safe_bcopy): Remove decl; no longer has that name.
3618 (main): Coalesce #if into single bit of code, for simplicity.

3649 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3650 Bug#9642, but explicitly check that the buffer the overlay would
3651 be moved to is live and rearrange lines to make sure that errors
3652 will not put the overlay in an inconsistent state.
3653 (Fdelete_overlay): Cosmetics.
3655 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3657 * w32term.c (my_bring_window_to_top): New function.
3658 (x_raise_frame): Use handle returned by DeferWindowPos, which

3691 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3692 Only r_alloc_inhibit_buffer_relocation needed to be added;
3693 the others were already declared.
3695 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3696 before checking whether it's out of range. Put the check inside
3698 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3700 2012-05-27 Ken Brown <kbrown@cornell.edu>

3707 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3708 defined on ralloc.c.
3710 * buffer.c [REL_ALLOC]: Remove prototypes of
3711 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3712 they are now on lisp.h.
3714 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3716 * search.c (search_buffer): Use it to inhibit relocation of buffer
3717 text while re_search_2 is doing its job, because re_search_2 is
3718 passed C pointers to buffer text. (Bug#11519)
3720 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3723 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3724 state after an additional call to move_it_in_display_line_to, keep
3725 the values of it->max_ascent and it->max_descent found for the

3728 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3731 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3733 Fix coding-related core dumps with gcc -ftrapv.
3734 The code was computing A - B, where A and B are pointers, and B is
3735 random garbage. This can lead to core dumps on platforms that
3736 have special pointer registers, and it also leads to core dumps on
3737 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3738 A - B only when B is initialized properly.

3762 gen_help_event to produce help-echo message in the echo area.
3763 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3766 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3768 * lread.c (read1): Simplify slightly to avoid an overflow warning
3769 with GCC 4.7.0 on x86-64.
3771 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3773 * bidi.c (bidi_mirror_char): Revert last change: an int is
3774 definitely wide enough here.
3776 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

3811 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3812 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3813 (validate_region): Omit unnecessary test for b <= e,
3814 since that's guaranteed by the previous test.
3815 (adjust_overlays_for_delete): Avoid pos + length overflow.
3816 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3817 (report_overlay_modification):

3819 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3828 not int, to avoid needless 32-bit limit on 64-bit hosts.
3829 (exec_byte_code): Use tighter memory-full test, one that checks
3830 for alloca overflow. Don't compute the address of the object just
3831 before an array, as that's not portable. Use EMACS_INT, not
3832 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3833 * callint.c (Fcall_interactively):
3834 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3847 (casify_object): Avoid integer overflow when overallocating buffer.
3848 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3851 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3852 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3856 For CCL_MapSingle, check that content and value are in int range.

3858 Check that Vcode_version_map_vector is a vector.
3859 (resolve_symbol_ccl_program): Check that vector header is in range.
3860 Always copy the vector, so that we can check its contents reliably
3861 now rather than having to recheck each instruction as it's being
3862 executed. Check that vector words fit in 'int'.
3863 (ccl_get_compiled_code, Fregister_ccl_program)
3864 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3865 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3867 contents are in range.
3868 (Fccl_execute_on_string): Check that status is in range.
3869 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3870 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3871 Accept and return EMACS_INT, not int, because callers can pass values

3878 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3880 avoid mishandling large integers.

3891 Don't rely on undefined behavior with signed left shift overflow.
3892 Don't assume unsigned int fits into fixnum, or that fixnum fits
3893 into unsigned int. Don't require max_code to be a valid fixnum;
3894 that's not true for gb10830 4-byte on a 32-bit host. Allow
3895 invalid_code to be a cons, for the same reason. Require code_offset
3896 to be a character. Avoid int overflow if max_char is close
3898 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3899 this is intended anyway and avoids some undefined behavior.
3900 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3901 INDEX_TO_CODE_POINT, as that's what it expects.
3902 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3903 * charset.h (DECODE_CHAR): Return int, not unsigned;
3904 this is what was intended anyway, and it avoids undefined behavior.
3905 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3906 integer-overflow issues.
3907 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3908 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3909 where the argument is EMACS_INT, and this behavior is not intended.
3910 * chartab.c (Fmake_char_table, Fset_char_table_range)
3911 (uniprop_get_decoder, uniprop_get_encoder):
3912 Don't assume fixnum fits in int.
3913 * cmds.c (move_point): New function, that does the gist of
3914 Fforward_char and Fbackward_char, but does so while checking
3915 for integer overflow more accurately.
3916 (Fforward_char, Fbackward_char): Use it.
3917 (Fforward_line, Fend_of_line, internal_self_insert)
3918 (internal_self_insert):
3919 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4619 what used to be in config.h, but not useful in #if.
4620 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4621 define them any more.
4622 (VAL_MAX): New macro.
4624 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4625 BITS_PER_EMACS_INT, in #if.

4628 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4629 * s/ms-w32.h (DATA_START):
4630 Move here from removed file m/intel386.h.
4631 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4632 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4634 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>

4700 2012-05-14 Glenn Morris <rgm@gnu.org>
4702 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4703 Put "libexec" before "bin", for the sake of init_callproc_1.
4705 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4707 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4709 * unexaix.c: Port to more-recent AIX compilers.
4710 (report_error, report_error_1, make_hdr, copy_sym)
4711 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4712 Make arguments const char *, not char *, to avoid violations of C
4713 standard and to fix some AIX warnings reported by Gilles Pion.
4715 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4717 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4718 already have overlays loaded.
4719 (handle_single_display_spec): Before returning without displaying
4720 fringe bitmap, synchronize the bidi iterator with the main display
4721 iterator, by calling iterate_out_of_display_property.
4722 (iterate_out_of_display_property): Detect buffer iteration by
4723 testing that it->string is a Lisp string.
4724 (get_next_display_element): When the current object is exhausted,
4725 and there's something on it->stack, call set_iterator_to_next to
4726 proceed with what's on the stack, instead of returning zero.
4727 (set_iterator_to_next): If called at the end of a Lisp string,
4728 proceed to consider_string_end without incrementing string
4729 position. Don't increment display vector index past the end of
4730 the display vector. (Bug#11417)
4731 (pos_visible_p): Don't report a position visible when move_it_to
4732 stopped at the last line of window, which happens to be scanned
4733 backwards by the bidi iteration. (Bug#11464)
4735 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4737 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4738 and right-margin display specs even if the spec is invalid or we
4739 are on a TTY, and thus unable to display on the fringes.
4740 That's because the text with the property will not be displayed anyway,
4741 so we need to signal to the caller that this is a "replacing"
4742 display spec. This fixes display when the spec is invalid or we
4745 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4747 * unexaix.c (make_hdr): Fix typo in prototype.
4748 This bug broke the build on AIX. Problem reported by Gilles Pion.
4750 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4752 * keyboard.c (kbd_buffer_get_event): Read special events also in
4753 batch mode. (Bug#11415)

4763 2012-05-12 Glenn Morris <rgm@gnu.org>

4778 Update dependencies.
4780 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4782 * xgselect.c (xg_select): Put maxfds+1 into a var.
4783 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4785 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4787 2012-05-10 Dave Abrahams <dave@boostpro.com>
4789 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4790 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4792 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4794 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4795 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4796 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4797 Initialize xd_registered_buses.
4799 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4801 Untag more efficiently if USE_LSB_TAG.
4802 This is based on a proposal by YAMAMOTO Mitsuharu in
4803 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4804 For an admittedly artificial (nth 8000 longlist) benchmark on
4805 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4806 Emacs's overall text size by 1%.
4807 * lisp.h (XUNTAG): New macro.
4808 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4809 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4810 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4811 * eval.c (Fautoload):
4812 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4813 * frame.h (XFRAME): Use XUNTAG.
4815 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4816 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4817 Remove unportable assumptions about print widths of types like
4819 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4820 intptr_t when converting between pointer and integer, to avoid GCC
4821 warnings about wrong width.
4823 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4825 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4826 stack for each reader_thread, instead of defaulting to 8MB
4827 determined by the linker. This avoids failures in creating
4828 subprocesses on Windows 7, see the discussion in this thread:
4829 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4831 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4833 Fix up display of the *Minibuf-0* buffer in the mini window.
4834 * keyboard.c (read_char): Don't clear the echo area if there's no
4836 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4837 contents of *Minibuf-0*) if there's no message displayed in its stead.
4839 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4841 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4844 2012-05-06 Chong Yidong <cyd@gnu.org>
4846 * lisp.mk (lisp): Update.
4848 2012-05-05 Jim Meyering <meyering@redhat.com>
4850 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4852 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4854 * data.c (PUT_ERROR): New macro.
4855 (syms_of_data): Use it. Add new error type `user-error'.
4856 * undo.c (user_error): New function.
4857 (Fprimitive_undo): Use it.
4858 * print.c (print_error_message): Adjust print style for `user-error'.
4859 * keyboard.c (user_error): New function.
4860 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4862 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4864 Do not limit current-time-string to years 1000..9999.
4865 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4866 (Fcurrent_time_string): Support any year that is supported by the
4867 underlying localtime representation. Don't use asctime, as it
4868 has undefined behavior for years outside the range -999..9999.
4870 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4872 Fix race conditions involving setenv, gmtime, localtime, asctime.
4873 Without this fix, interrupts could mess up code that uses these
4874 nonreentrant functions, since setting TZ invalidates existing
4875 tm_zone or tzname values, and since most of these functions return
4876 pointers to static storage.
4877 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4878 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4879 Grow the critical sections to include not just invoking
4880 localtime/gmtime, but also accessing these functions' results
4881 including their tm_zone values if any, and any related TZ setting.
4882 (format_time_string): Last arg is now struct tm *, not struct tm **,
4883 so that the struct tm is saved in the critical section.
4884 All callers changed. Simplify allocation of initial buffer, partly
4885 motivated by the fact that memory allocation needs to be outside
4886 the critical section.
4888 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4890 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4891 with RESET_INTERVAL.
4893 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4894 Remove duplicated buffer name initialization.
4896 2012-05-02 Jim Meyering <jim@meyering.net>
4898 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4900 * xfns.c (x_window): Use xstrdup (Bug#11375).
4902 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4904 * xdisp.c (pos_visible_p): If already at a newline from the
4905 display string before the 'while' loop, don't walk back the glyphs
4906 from it3.glyph_row. Solves assertion violation when the display
4907 string begins with a newline (egg.el). (Bug#11367)
4909 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4911 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4914 2012-05-01 Glenn Morris <rgm@gnu.org>
4916 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4917 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4918 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4919 All were removed before 23.1.
4921 * dispnew.c: Remove HAVE_LIBNCURSES test;
4922 it is always true on relevant platforms.
4924 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4925 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4927 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4929 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4931 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4932 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4935 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4937 Do not avoid creating empty evaporating overlays (Bug#9642).
4938 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4939 That is, do not delete an evaporating overlay if it becomes
4940 empty after its bounds are adjusted to fit within its buffer.
4941 This fix caused other problems, and I'm reverting it until we get
4942 to the bottom of them.
4944 2012-04-27 Chong Yidong <cyd@gnu.org>
4946 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4948 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4950 * xdisp.c (pos_visible_p): If the window start position is beyond
4951 ZV, start the display from buffer beginning. Prevents assertion
4952 violation in init_iterator when the minibuffer window is scrolled
4955 * window.c (window_scroll_pixel_based): Likewise.
4957 2012-04-27 Chong Yidong <cyd@gnu.org>
4959 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4961 2012-04-27 Glenn Morris <rgm@gnu.org>
4963 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4964 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4966 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4968 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4969 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4971 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4973 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4974 display element, check also the underlying string or buffer
4975 character. (Bug#11341)
4977 * w32menu.c: Include w32heap.h.
4978 (add_menu_item): If the call to AppendMenuW (via
4979 unicode_append_menu) fails, disable Unicode menus only if we are
4980 running on Windows 9X/Me.
4982 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4984 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4985 (xgetint): Add missing shift for LSB tags.
4987 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4989 * keyboard.c (read_char): Don't wipe echo area for select window
4990 events: These might get delayed via `mouse-autoselect-window'
4993 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4995 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4996 manipulation of :loaded-from data.
4998 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5000 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5001 now a cons (bug#11311).
5003 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5005 Do not create empty overlays with the evaporate property (Bug#9642).
5006 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5007 if it becomes empty after its bounds are adjusted to fit within
5008 its buffer. Without this fix, in a nonempty buffer (let ((o
5009 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5010 yields an empty overlay that has the evaporate property, which is
5011 not supposed to happen.
5013 Fix minor GTK3 problems found by static checking.
5014 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5015 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5016 (struct _EmacsFixedClass, emacs_fixed_get_type):

5026 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5028 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5029 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5031 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5033 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5034 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5035 (__malloc_size_t, __malloc_ptrdiff_t):
5036 Remove. All uses removed, replaced by the definiens if needed,
5037 since we can assume C89 or better now.
5038 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

5048 Define using prototypes, not old style.
5049 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5050 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5051 (align): Don't assume that signed integer overflow wraps around.
5052 Omit unused local var.
5053 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

5113 * alloc.c: Handle unusual debugging option combinations.
5114 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5115 since the two debugging options are incompatible.
5116 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5118 (mem_init, mem_insert, mem_insert_fixup):
5119 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5128 * sysdep.c [__FreeBSD__]: Minor cleanups.
5129 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5130 Use Emacs indenting style more consistently. Avoid some casts.
5131 Use 'double' consistently rather than mixing 'float' and 'double'.
5133 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5135 * sysdep.c (list_system_processes, system_process_attributes):
5136 Add implementation for FreeBSD (Bug#5243).

5142 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
5144 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
5145 It is never used otherwise.
5147 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
5149 * print.c (print_preprocess): Only check print_depth if print-circle
5151 (print_object): Check for cycles even when print-circle is nil and
5152 print-gensym is t, but only check print_depth if print-circle is nil.
5154 2012-04-20 Chong Yidong <cyd@gnu.org>
5156 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5157 set the status to "failed" and ensure that sentinel is run.
5159 2012-04-20 Glenn Morris <rgm@gnu.org>

5170 row, return zero immediately.
5171 (try_cursor_movement): If inside continuation line, don't back up
5172 farther than the first row after the header line, if any.
5173 Don't consider the header-line row as "partially visible", even if
5174 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5176 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5212 New extern decls, to avoid calling undeclared functions.
5213 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5214 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5215 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5216 (NEED_MEM_INSERT): New macro.
5217 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5218 Remove one incorrect comment and fix another.

5230 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5231 [REL_ALLOC]: ... to here, to check interface.
5232 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5233 Remove decls. This fixes an "It stinks!".
5235 * alloc.c (which_symbols): Fix alignment issue / type clash.
5237 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5239 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5240 (struct Lisp_Misc_Any): Likewise.

5250 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5252 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5253 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5254 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5255 * s/netbsd.h, s/sol2-6.h:
5256 Remove definition of GC_MARK_STACK, since the default now works.
5257 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5258 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5259 no longer the default.
5260 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5262 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5264 * lread.c (lisp_file_lexically_bound_p):

5285 2012-04-11 Daniel Colascione <dancol@dancol.org>
5287 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5288 against is gone. It's better to use vfork now so that when Cygwin
5289 gains a new, working vfork, we use it automatically (bug#10398).
5291 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5293 * window.c (save_window_save): Obey window-point-insertion-type.

5309 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5311 * w32.c (w32_delayed_load): Record the full path of the library
5312 being loaded (bug#10424).
5314 2012-04-09 Glenn Morris <rgm@gnu.org>
5316 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5317 not just in the obarray, before snarfing them. (Bug#11036)
5319 * Makefile.in ($(leimdir)/leim-list.el):
5320 Pass EMACS rather than BUILT_EMACS.
5322 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5324 * process.c (make_process):
5325 * process.h: Add integer `gnutls_handshakes_tried' member to
5328 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5329 Add convenience `GNUTLS_LOG2i' macro.
5331 * gnutls.c (gnutls_log_function2i): Convenience log function.
5332 (emacs_gnutls_read): Use new log functions,
5333 `gnutls_handshakes_tried' process member, and
5334 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5335 attempts per process (connection).
5337 2012-04-09 Chong Yidong <cyd@gnu.org>
5339 * eval.c (Fuser_variable_p, user_variable_p_eh)

5344 * minibuf.c (Fread_variable): Callers changed.
5346 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5348 * xdisp.c (set_cursor_from_row): If the display string appears in
5349 the buffer at position that is closer to point than the position
5350 after the display string, display the cursor on the first glyph of
5351 the display string. Fixes cursor display when a 'display' text
5352 property immediately follows invisible text. (Bug#11094)
5354 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5356 composite.c: use 'double' consistently
5357 * composite.c (get_composition_id): Use 'double' consistently
5358 instead of converting 'float' to 'double' and vice versa; this is
5359 easier to understand and avoids a GCC warning.
5361 2012-04-09 Glenn Morris <rgm@gnu.org>
5363 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5364 preparation for dumping it with emacs. (Bug#4789)
5365 (leimdir): New variable.
5366 ($(leimdir)/leim-list.el): New rule.

5383 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5385 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5386 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5387 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5388 objects, as mark_maybe_pointer will catch them otherwise.
5389 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5390 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5392 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5394 Fix typo that broke non-Windows builds.
5395 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5399 Support building on MS-Windows with libxml2.
5401 * makefile.w32-in (OBJ2): Add xml.$(O).
5402 (GLOBAL_SOURCES): Add xml.c.
5403 ($(BLD)/xml.$(O)): New dependency list.
5405 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5406 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5407 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5408 [!WINDOWSNT]: New macros.
5409 (init_libxml2_functions, libxml2_loaded_p): New functions.
5410 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5411 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5412 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5413 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5415 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5416 Call init_libxml2_functions before calling libxml2 functions.
5417 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5419 * emacs.c: Don't include libxml/parser.h.
5420 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5421 xmlCleanupParser directly.
5423 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5425 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5427 * indent.c (Fvertical_motion): If there is a display string at
5428 point, use it.vpos to compute how many lines to backtrack after
5429 move_it_to point. (Bug#11133)
5431 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5433 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5434 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5435 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5436 macros related to unification of CJK characters. For the details,
5437 see the discussion following the message here:
5438 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5440 2012-04-04 Chong Yidong <cyd@gnu.org>
5442 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5444 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5446 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5447 instead of alloca. (Bug#11138)
5449 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5451 * w32menu.c (is_simple_dialog): Properly check lisp types.
5454 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5456 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5457 position we get to after a call to move_it_to fails the
5458 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5459 only if we wind up in a string from display property. (Bug#11063)
5461 * window.c (Fdelete_other_windows_internal): Invalidate the row
5462 and column information about mouse highlight, so that redisplay
5463 restores it after reallocating the glyph matrices. (Bug#7464)
5465 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5466 string comes from a `display' text property, use the buffer
5467 position of that property as if we actually saw that position in
5469 (move_it_by_lines): Remove the assertion that
5470 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5471 violated when there's a before-string at the beginning of a line.
5474 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5476 * xdisp.c (append_space_for_newline): If the default face was
5477 remapped, use the remapped face for the appended newline.
5478 (extend_face_to_end_of_line): Use the remapped default face for
5479 extending the face to the end of the line.
5480 (display_line): Call extend_face_to_end_of_line when the default
5481 face was remapped. (Bug#11068)
5483 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5485 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5487 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5489 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5491 2012-03-27 Glenn Morris <rgm@gnu.org>
5493 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5496 2012-03-26 Kenichi Handa <handa@m17n.org>
5498 * dispextern.h (struct glyph): Fix previous change. Change the
5499 bit length of glyphless.ch to 25 (Bug#11082).
5501 2012-03-26 Chong Yidong <cyd@gnu.org>
5503 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5504 (command_loop_1): Use it; inhibit selection update for
5505 handle-select-window too (Bug#8996).
5507 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5509 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5511 2012-03-25 Kenichi Handa <handa@m17n.org>
5513 * dispextern.h (struct glyph): Change the bit length of
5514 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5516 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5518 * s/ms-w32.h (tzname): Include time.h before redirecting to
5519 _tzname. Fixes the MSVC build. (Bug#9960)
5521 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5523 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5526 * xterm.c (XTread_socket): Only modify handling_signal if
5527 !SYNC_INPUT. (Bug#11080)
5529 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5531 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5532 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5533 when fetching a multibyte character consumes more bytes than
5534 CHAR_BYTES returns, due to unification of CJK characters in
5535 string_char. (Bug#11073)
5537 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5539 * process.c (wait_reading_process_output): Handle pty disconnect
5540 by refraining from sending oneself a SIGCHLD (bug#10933).
5542 2012-03-22 Chong Yidong <cyd@gnu.org>
5544 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5546 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5547 Mark string as coming from a prefix property.
5548 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5549 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5551 2012-03-21 Chong Yidong <cyd@gnu.org>
5553 * xfaces.c (Vface_remapping_alist): Doc fix.
5555 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5557 * w32proc.c (Fw32_set_console_codepage)
5558 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5561 2012-03-20 Chong Yidong <cyd@gnu.org>
5563 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5564 to reflect default non-nil value of redisplay-dont-pause.
5566 2012-03-19 Kenichi Handa <handa@m17n.org>
5568 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5569 it fit in a valid range (Bug#11003).
5571 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5573 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5574 that is not from display property, accept the row as a "cursor
5575 row" if one of the string's character has a non-nil `cursor'
5576 property. Fixes cursor positioning when there are newlines in
5577 overlay strings, e.g. in icomplete.el. (Bug#11035)
5579 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5581 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5583 2012-03-12 Chong Yidong <cyd@gnu.org>
5585 * eval.c (inhibit_lisp_code): Rename from
5586 inhibit_window_configuration_change_hook; move from window.c.
5588 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5589 * window.c (run_window_configuration_change_hook)
5590 (syms_of_window): Callers changed.
5592 2012-03-11 Chong Yidong <cyd@gnu.org>

5601 is visible (Bug#10955).
5603 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5605 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5607 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5609 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5610 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5613 2012-03-03 Glenn Morris <rgm@gnu.org>
5615 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5617 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5619 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5620 position past the first glyph_row that ends at ZV. (Bug#10902)
5621 (redisplay_window, next_element_from_string): Fix typos in
5623 (redisplay_window): Pass to move_it_vertically the margin in
5624 pixels, not in screen lines.
5626 2012-03-02 Glenn Morris <rgm@gnu.org>
5628 * buffer.c (buffer-list-update-hook): Doc fix.
5630 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5632 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5633 push_it before setting up the iterator for the first overlay
5634 string, even if we have an empty string loaded.
5635 (next_overlay_string): If there's an empty string on the iterator
5636 stack, pop the stack. (Bug#10903)
5638 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5640 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5641 Suggested by Stefan Monnier in
5642 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5643 * alloc.c (widen_to_Lisp_Object): New static function.
5644 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5645 and widening them to Lisp_Objects. This would work even if
5646 USE_LSB_TAG is defined and wide integers are used, which might
5647 happen in a future version of Emacs.
5649 2012-02-25 Chong Yidong <cyd@gnu.org>
5651 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5654 * xselect.c (Fx_selection_exists_p): Doc fix.
5655 (x_clipboard_manager_save_all): Print an informative message
5656 before saving to clipboard manager.
5658 2012-02-24 Chong Yidong <cyd@gnu.org>
5660 * keyboard.c (process_special_events): Handle all X selection
5661 requests in kbd_buffer, not just the next one (Bug#8869).
5663 2012-02-23 Chong Yidong <cyd@gnu.org>
5665 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5666 call when setting menu-bar-lines and tool-bar-lines parameters.
5667 (unwind_create_frame_1): New helper function.
5669 * window.c (inhibit_window_configuration_change_hook): New var.
5670 (run_window_configuration_change_hook): Obey it.
5671 (syms_of_window): Initialize it.
5673 2012-02-22 Chong Yidong <cyd@gnu.org>

5688 when computing $valmask.
5690 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5691 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5692 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5693 It's useless in that case, and it can cause problems on hosts
5694 that allocate halves of EMACS_INT values separately.
5695 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5696 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5697 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5698 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5699 it avoids undefined behavior on hosts where shifting right by more
5700 than the word width has undefined behavior.
5702 2012-02-19 Chong Yidong <cyd@gnu.org>
5704 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5705 (Funhandled_file_name_directory, Ffile_name_as_directory)

5707 (Fsubstitute_in_file_name): Protect against invalid file handler
5708 return values (Bug#10845).
5710 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5712 * .gdbinit (pitx): Fix incorrect references to fields of the
5715 2012-02-17 Chong Yidong <cyd@gnu.org>

5722 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5724 2012-02-15 Chong Yidong <cyd@gnu.org>
5726 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5727 marked as special. Also, starting docstrings with * is obsolete.

5742 2012-02-12 Chong Yidong <cyd@gnu.org>
5744 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5745 as that creates a dangerous corner case.
5747 * window.c (Fdelete_window_internal): Invalidate the mouse
5748 highlight (Bug#9904).
5750 2012-02-12 Glenn Morris <rgm@gnu.org>
5752 * xselect.c (Fx_own_selection_internal)
5753 (Fx_get_selection_internal, Fx_disown_selection_internal)
5754 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5755 * nsselect.m (Fx_own_selection_internal)
5756 (Fx_disown_selection_internal, Fx_selection_exists_p)
5757 (Fx_selection_owner_p, Fx_get_selection_internal):
5758 Sync docs and argument specs with the xselect.c versions.
5760 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5762 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5764 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5766 * w32select.c (Fx_selection_exists_p): Sync doc string and
5767 argument list with xselect.c. (Bug#10783)

5780 2012-02-07 Chong Yidong <cyd@gnu.org>
5782 * buffer.c (Fbuffer_local_variables)
5783 (buffer_lisp_local_variables): Handle unbound vars correctly;
5784 don't let Qunbound leak into Lisp.
5786 2012-02-07 Glenn Morris <rgm@gnu.org>
5788 * image.c (Fimagemagick_types): Doc fix.
5790 * image.c (imagemagick-render-type): Change it from a lisp object
5791 to an integer. Move the doc here from the lisp manual.

5796 * doc.c (store_function_docstring): Avoid applying docstring of
5797 alias to base function (Bug#2603).

6317 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
6318 verifies glyph row's hash code--we have just reallocated the

6327 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Ensure ROW's
6328 attributes are tested _before_ calling verify_row_hash, to protect
6329 against GCC re-ordering of the tests. (Bug#10164)
6331 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>
6333 * xterm.h (struct x_output): net_wm_state_hidden_seen is new.

6350 2011-11-28 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6352 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
6353 of scroll runs so as to avoid assigning disabled bogus rows and
6354 unnecessary graphics copy operations.
6356 2011-11-27 Eli Zaretskii <eliz@gnu.org>
6358 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.
6359 (snprintf) [_MSC_VER]: Redirect to _snprintf.
6360 (strtoll) [_MSC_VER]: Redirect to _strtoi64.
6361 (malloc, free, realloc, calloc): Redirect to e_* only when
6364 * lisp.h (GCTYPEBITS): Move before first use.
6365 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6366 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
6367 this macro definition.
6369 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
6372 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

6390 Indent for consistency with usual Emacs style.
6392 2011-11-25 Eli Zaretskii <eliz@gnu.org>
6394 * xdisp.c (redisplay_window): If cursor row is not fully visible
6395 after recentering, and scroll-conservatively is set to a large
6396 number, scroll window by a few more lines to make the cursor fully
6397 visible and out of scroll-margin. (Bug#10105)
6398 (start_display): Don't move to the next line if the display should
6399 start at a newline that is part of a display vector or an overlay

6480 Otherwise, valgrind does not work on some platforms.
6481 Problem reported by Andreas Schwab in
6482 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6483 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6484 is set, removing the need for VIRT_ADDRESS_VARIES.
6485 (PURE_P): Use a more-efficient implementation that needs just one
6486 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6487 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6488 to 4 (xorl, subq, cmpq, setbe).
6489 * alloc.c (pure): Always extern now, since that's the
6490 VIRT_ADDR_VARIES behavior.
6491 (PURE_POINTER_P): Use a single comparison, not two, for
6492 consistency with the new puresize.h.
6493 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6494 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6500 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6501 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6502 behave as if the cursor position were at the window margin.
6504 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6505 and the cursor position is out of bounds, behave as if the cursor
6506 position were at the window margin. (Bug#10075)
6508 2011-11-18 Chong Yidong <cyd@gnu.org>
6510 * window.c (Fwindow_combination_limit): Make first argument
6511 non-optional, since it is meaningless for live windows like the

6526 hash values of the two rows.
6527 (copy_row_except_pointers): Preserve the used[] arrays and the
6528 hash values of the two rows. (Bug#10035)
6529 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
6531 * xdisp.c (row_hash): New function, body extracted from
6532 compute_line_metrics.
6533 (compute_line_metrics): Call row_hash, instead of computing the
6536 * dispnew.c (verify_row_hash): Call row_hash for computing the
6537 hash code of a row, instead of duplicating code from xdisp.c.
6539 * dispextern.h (row_hash): Add prototype.
6541 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6543 * frame.c (delete_frame): Don't delete the terminal when the last
6544 X frame is closed if emacs is built with GTK toolkit.

6566 (Fset_window_nest): Rename to Fset_window_combination_limit.
6567 (Vwindow_nest): Rename to Vwindow_combination_limit.
6568 (recombine_windows, make_parent_window, make_window)
6569 (Fsplit_window_internal, saved_window)
6570 (Fset_window_configuration, save_window_save): Rename all
6571 occurrences of window_nest to window_combination_limit.
6573 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6575 * image.c (imagemagick_load_image): Fix typo.
6577 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6579 * xdisp.c (display_line): Move the call to
6580 highlight_trailing_whitespace before the call to
6581 compute_line_metrics, since the latter needs to see the final
6582 faces of all the glyphs to compute ROW's hash value.
6583 Fixes assertion violations in row_equal_p. (Bug#10035)
6585 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6587 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6592 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6593 with user-defined heap size. Bump the default size of the temacs
6594 heap to 27MB, to avoid memory warning when running temacs.
6595 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6597 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
6598 current_matrix and desired_matrix. (Bug#9990)
6599 (verify_row_hash) [XASSERTS]: New function.

6644 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6646 Avoid some portability problems by eschewing 'extern inline' functions.
6647 The trivial performance wins aren't worth the portability hassles; see
6648 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6650 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6651 (window_box_width, window_box_left, window_box_left_offset)
6652 (window_box_right, window_box_right_offset): Undo previous change,
6653 by removing the "extern"s.
6654 * intervals.c (adjust_intervals_for_insertion)
6655 (adjust_intervals_for_deletion): Undo previous change,
6656 making these static again.
6657 (offset_intervals, temp_set_point_both, temp_set_point)
6658 (copy_intervals_to_string): No longer inline.
6659 * xdisp.c (window_text_bottom_y, window_box_width)

6683 2011-11-07 Martin Rudalics <rudalics@gmx.at>
6685 * window.h: Declare delete_all_child_windows instead of

6696 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
6698 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6699 This is also needed for porting to any host where GC_MARK_STACK is
6700 not GC_MAKE_GCPROS_NOOPS.
6701 (which_symbols): Use it.
6703 2011-11-07 Kenichi Handa <handa@m17n.org>

6716 * xmenu.c (cleanup_widget_value_tree): New function.
6717 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6724 (window_box_width, window_box_left, window_box_left_offset)
6725 (window_box_right, window_box_right_offset): Declare extern.
6726 Otherwise, these inline functions do not conform to C99 and
6727 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6728 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6729 * intervals.c (adjust_intervals_for_insertion)
6730 (adjust_intervals_for_deletion): Now extern, because otherwise the
6731 extern inline functions 'offset_intervals' couldn't refer to it.
6732 (static_offset_intervals): Remove.
6733 (offset_intervals): Rewrite using the old contents of
6734 static_offset_intervals. The old version didn't conform to C99
6735 because an extern inline function contained a reference to an
6736 identifier with static linkage.
6738 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6740 * keyboard.c (interrupt_signal): Don't call kill-emacs while in
6743 2011-11-06 Eli Zaretskii <eliz@gnu.org>

6757 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6758 (Fwindow_vscroll): Doc fix.
6759 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6760 argument, since it makes no sense to pass a live window and for
6761 consistency with window-child.

6840 2011-11-04 Eli Zaretskii <eliz@gnu.org>
6842 * xdisp.c (note_mouse_highlight): If either of
6843 previous/next-single-property-change returns nil, treat that as
6844 the beginning or the end of the buffer. (Bug#9955)
6846 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6848 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

6868 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6869 Don't stop backward scan on the continuation glyph, even though
6870 its CHARPOS is positive.
6871 (mouse_face_from_buffer_pos, note_mouse_highlight):
6872 Rename cover_string to disp_string.
6874 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6876 * window.c (temp_output_buffer_show): Don't use
6877 Vtemp_buffer_show_specifiers.
6878 (Vtemp_buffer_show_specifiers): Remove unused variable.
6880 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6882 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented

6908 so that this new function doesn't get optimized away by a
6909 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6911 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6913 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6915 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6917 Fix the `xbytecode' command.

6931 2011-10-29 Glenn Morris <rgm@gnu.org>
6933 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6934 Not clear what it was for, and it causes various bugs. (Bug#9839)
6936 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6938 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6939 possible random value that matches one of those tested as
6940 condition to clear the mouse face.
6942 2011-10-28 Chong Yidong <cyd@gnu.org>
6944 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6946 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6948 * window.c (make_window): Initialize phys_cursor_on_p.
6950 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>

6958 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6960 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6961 <oslsachem@gmail.com> for helping to debug this.
6963 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6964 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6965 (g_b_init_get_glyph_outline_w): New static variables.
6966 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6967 (GetGlyphOutlineW_Proc): New typedefs.
6968 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6969 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6971 (w32font_open_internal, compute_metrics):
6972 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6973 instead of calling the "wide" APIs directly.
6975 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6977 * w32.h (syms_of_w32font): Add prototype.
6979 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6981 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6982 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6983 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

6988 * process.c (make_process): Set gnutls_state to NULL.
6990 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6991 non-NULL, regardless of GNUTLS_INITSTAGE.
6992 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6993 an error. Set process slots as soon as we allocate them.

7003 * process.c (make_process): Initialize GnuTLS credentials to NULL.
7004 (deactivate_process): Call emacs_gnutls_deinit.
7006 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

7011 * w32reg.c (x_get_string_resource): Silence compiler warnings.
7013 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
7015 * w32fns.c (w32_default_color_map): New function,
7016 extracted from Fw32_default_color_map.
7017 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
7019 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
7021 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
7023 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
7025 * keyboard.c (test_undefined): New function (bug#9751).
7026 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7028 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7030 * sysdep.c (init_sys_modes): Fix the check for the controlling
7031 terminal (Bug#6649).
7033 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7035 * dispextern.h (struct bidi_it): New member next_en_type.
7037 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7038 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7039 current character, check also for next_en_type being WEAK_EN.
7040 (bidi_resolve_weak): Don't enter the expensive loop if the current
7041 position is before next_en_pos. Record the bidi type of the first
7042 non-ET, non-BN character we find, in addition to its position.
7043 (bidi_level_of_next_char): Invalidate next_en_type when
7044 next_en_pos is over-stepped.
7046 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7048 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7049 * editfns.c: Rewrite current-time-zone so that it invokes
7050 the equivalent of (format-time-string "%Z") to get the time zone name.
7051 This fixes a bug when the time zone name contains characters that
7052 need converting from the system time locale to Emacs internal format.
7053 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7054 that patch fixed format-time-string to do the conversion, but
7055 I forgot to fix current-time-zone.
7056 (format_time_string): New function, containing most of
7057 what Fformat_time_string used to contain.
7058 (Fformat_time_string): Rewrite in terms of format_time_string.
7059 This doesn't change this function's behavior.
7060 (current-time-zone): Rewrite to use format_time_string.
7061 This fixes the bug reported by Michael Schierl in
7062 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7063 Jason Rumney's 2007-06-07 change worked around this bug, but
7065 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7067 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7069 * xdisp.c (start_display): If the character at POS is displayed
7070 via a display vector, reset IT->current.dpvec_index to zero.
7071 (try_window_reusing_current_matrix): If a line ends in a display
7072 vector or the next line starts in a display vector, continue
7073 redrawing the window even though the character position of
7074 start_row was reached.
7077 2011-10-18 Chong Yidong <cyd@gnu.org>
7079 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7080 with nobreak-char-display too.
7082 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7084 Fix part 3 of bug#9771.
7085 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7086 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7087 non-neutral characters if the current character is a paragraph
7088 separator (a.k.a. Newline). This avoids running the same
7089 expensive loop twice, once when we consume the preceding newline
7090 and the other time when the line actually needs to be displayed.
7091 Avoid the loop when we see neutrals on the base embedding level
7092 following a character whose directionality is the same as the
7093 paragraph's. This avoids running the expensive loop when a line
7094 ends in a long sequence of neutrals, like control characters.
7095 Add assertion against STRONG_AL type. Slightly rearrange code
7096 that determines the type of a neutral given the first non-neutral
7098 (bidi_level_of_next_char): Set next_en_pos to zero when
7099 invalidating its info.
7101 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7103 * xdisp.c (push_display_prop): Determine whether to record string
7104 or buffer position by IT->string, not by IT->method. Allow
7105 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7106 (move_it_vertically_backward): Don't look for character position
7107 immediately after the newline when in a continuation line.
7110 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7112 * window.c (coordinates_in_window): Rewrite and delabelize
7113 vertical border check. (Bug#5357) (Bug#9618)
7115 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7117 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7118 errors in XSetWindowBorder (bug#9310).
7120 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7122 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7123 avoid crash when xmalloc overrun checking is enabled.
7125 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7127 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7128 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7129 cursor motion with <left> and <right> arrow keys.
7131 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7132 some callers set that themselves.
7134 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7136 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7137 display string and the previous row comes from the same string and
7138 is empty. (Bug#9739) (Bug#9738)
7140 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7142 * doc.c (get_doc_string): Encode file name (bug#9735).
7144 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7146 * bidi.c (bidi_level_of_next_char):
7147 * xdisp.c (get_visually_first_element): Remove old incorrect
7148 comments regarding the Unicode Line Separator character.
7150 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7152 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7154 * alloc.c (Fgc_status): Do not access beyond zombies array
7155 boundary if nzombies > MAX_ZOMBIES.
7156 * alloc.c (dump_zombies): Add missing format specifier.
7158 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7160 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7161 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7163 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7164 Some packages use them to denote characters with modifiers.
7166 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7168 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7169 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7170 matching a pp-number. Rename parameter var to var1.
7172 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7174 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7176 2011-10-08 Glenn Morris <rgm@gnu.org>
7178 * callint.c (Fcall_interactively): Give a more explicit error for the
7179 'c' case with a non-character input. (Bug#8479)
7181 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7183 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7185 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7186 lines that are hscrolled on the left.
7188 * dispnew.c (buffer_posn_from_coords): Account for a possible
7189 presence of header-line. (Bug#4426)
7191 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7193 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7194 Don't advertise functionality which we discourage or doesn't work.
7196 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7198 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7199 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7200 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7201 this makes Emacs dump core during garbage collection on rare
7202 occasions. sizeof is obviously inferior to offsetof here, so
7203 stick with offsetof.
7204 (GC_POINTER_ALIGNMENT): New macro.
7205 (mark_memory): Omit 3rd (offset) arg; caller changed.
7206 Don't assume EMACS_INT alignment is the same as pointer alignment.
7208 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7210 * keyboard.c (read_key_sequence_remapped): New var.
7211 (read_key_sequence): Compute remapping in the right buffer.
7212 (command_loop_1): Use read_key_sequence's remapping directly.
7214 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7216 * dired.c (file_name_completion): Don't expand file name.
7217 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7218 before checking file name handler.
7220 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7221 they've been requested explicitly (bug#9591).
7223 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7225 * keymap.c (Fsingle_key_description): Use make_specified_string
7226 instead of build_string to build string from push_key_description.
7229 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7231 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7232 This fixes a Y2038 bug on 64-bit hosts.
7233 * buffer.c (reset_buffer):
7234 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7235 (Fclear_buffer_auto_save_failure):
7236 Use 0, not -1, to represent an unset failure time, since time_t
7237 might not be signed.
7239 Remove dependency on glibc malloc internals.
7240 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7241 Move back here from lisp.h, but with their new implementations.
7242 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7243 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7244 * charset.c (charset_table_init): New static var.
7245 (syms_of_charset): Use it instead of xmalloc. This removes a
7246 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7247 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7248 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7249 Move back to alloc.c.
7250 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7251 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7253 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7255 * nsterm.m (windowDidResize): Call x_set_window_size only when
7256 ns_in_resize is true. Otherwise set pixelwidth/height and
7257 call change_frame_size (Bug#9628).
7259 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7261 Port --enable-checking=all to Fedora 14 x86-64.
7262 * charset.c (syms_of_charset): Also account for glibc malloc's
7263 internal overhead when calculating the initial malloc maximum.
7265 Port --enable-checking=all to Fedora 14 x86.
7266 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7268 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7269 (overrun_check_realloc, overrun_check_free):
7270 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7271 That way, xmalloc returns a properly-aligned pointer even if
7272 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7273 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7274 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7275 into account when calculating the initial malloc maximum.
7276 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7277 Move here from alloc.c, so that charset.c can use it too.
7278 Properly align; the old code wasn't right for common 32-bit hosts
7279 when configured with --enable-checking=all.
7280 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7281 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7283 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7285 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7288 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7290 * xdisp.c (compute_display_string_end): If there's no display
7291 string at CHARPOS, return -1.
7293 * bidi.c (bidi_fetch_char): When compute_display_string_end
7294 returns a negative value, treat the character as a normal
7295 character not covered by a display string. (Bug#9624)
7297 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7299 * lread.c (Fread_from_string): Fix typo in docstring.
7301 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7303 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7304 newline, reseat the iterator instead of bidi-iterating there one
7305 character at a time. (Bug#9610)
7306 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7307 TO_CHARPOS if the bidi iterator is at base embedding level.
7309 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7311 * lread.c (readevalloop): Use correct code for NBSP.
7312 (read1): Likewise. (Bug#9608)
7314 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7316 * dbusbind.c (Fdbus_register_signal): When service is not
7317 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7319 2011-09-25 Glenn Morris <rgm@gnu.org>
7321 * buffer.c (truncate-lines): Doc fix.
7323 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7325 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7326 (Fset_window_next_buffers): Doc fix.
7328 2011-09-24 Glenn Morris <rgm@gnu.org>
7330 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7332 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7334 Fix minor problems found by static checking.
7335 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7336 * indent.c (Fvertical_motion): Fix == vs = typo.
7338 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7340 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7341 Default value is now t. Doc fix.
7343 * indent.c (Fvertical_motion): Compute and apply the overshoot
7344 logic when moving up, not only when moving down. Fix the
7345 confusing name and values of the it_overshoot_expected variable;
7346 logic changes accordingly. (Bug#9254) (Bug#9549)
7348 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7349 CHARPOS is covered by a display string which includes newlines.
7350 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7351 is covered by a display string with embedded newlines.
7353 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7355 * dbusbind.c (Fdbus_register_signal): Add match rule to
7356 Vdbus_registered_objects_table. (Bug#9581)
7357 (Fdbus_register_method, Vdbus_registered_objects_table):
7360 2011-09-24 Jim Meyering <meyering@redhat.com>
7362 do not ignore write error for any output size
7363 The previous change was incomplete.
7364 While it makes emacs --batch detect the vast majority of stdout
7365 write failures, errors were still ignored whenever the output size is
7366 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7367 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7368 && echo FAIL: ignored write error
7369 FAIL: ignored write error
7370 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7371 && echo FAIL: ignored write error
7372 FAIL: ignored write error
7373 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7375 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7377 * emacs.c (Fkill_emacs): In noninteractive mode exit
7378 non-successfully if a write error occurred on stdout. (Bug#9574)
7380 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7382 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7385 * dispextern.h (struct it): Update the comment documenting what
7388 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7390 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7391 a display string, extend search for cursor position to end of row.
7392 (find_row_edges): If the row ends in a newline from a display
7393 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7394 Handle the case of a display string with multiple newlines.
7395 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7396 non-empty line. Fixes confusing cursor motion with arrow keys at
7397 the beginning of a line that starts with whitespace.
7399 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7401 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7404 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7406 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7409 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7411 * xdisp.c (display_line): Record maximum and minimum buffer
7412 positions even if no glyphs were produced (e.g., by a zero-width
7413 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7414 buffer positions that will be removed from the glyph row because
7416 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7417 column is beyond frame width: don't subtract 1 "pixel" when
7418 computing width of the stretch.
7419 (reseat_at_next_visible_line_start): Undo the change made on
7420 2011-09-17 that saved paragraph information and restored it after
7421 the call to `reseat'. (Bug#9545)
7423 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7425 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7426 and turn window cursor on if cleared (Bug#9415).
7428 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7430 * search.c (boyer_moore): Take unibyte characters from pattern
7431 literally. (Bug#9458)
7433 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7435 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7437 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7439 Fix minor problem found by static checking.
7440 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7441 initialized, to pacify gcc -Wuninitialized.
7443 * fileio.c: Report proper errno when syscall falls.
7444 (Finsert_file_contents): Save and restore errno,
7445 so that report_file_error outputs the correct diagnostic.
7446 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7448 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7450 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7452 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7454 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7455 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7457 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7459 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7460 about the current paragraph and restore it after the call to reseat.
7462 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7463 (bidi_find_paragraph_start): Search back for paragraph beginning
7464 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7465 (bidi_move_to_visually_next): Only trigger paragraph-related
7466 computations when the last character is a newline or at EOB, not
7467 just any NEUTRAL_B. (Bug#9470)
7469 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7470 truncated lines if point is covered by a display string. (Bug#9524)
7472 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7474 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7475 (cons_to_x_long): New function.
7476 (lisp_data_to_selection_data): Use it. Correct the test for
7477 short-versus-long data; it was negated. Break out of vector
7478 loop, for efficiency, when a long datum is discovered.
7480 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7482 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7484 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7486 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7487 GCC PR/17406) by declaring this function with external scope.
7489 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7491 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7492 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7494 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7496 * editfns.c (Fformat): Correctly handle text properties on "%%".
7498 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7500 * xterm.c (x_draw_composite_glyph_string_foreground):
7501 * w32term.c (x_draw_composite_glyph_string_foreground):
7502 * term.c (encode_terminal_code):
7503 * composite.c (composition_update_it, get_composition_id):
7504 * xdisp.c (get_next_display_element)
7505 (fill_composite_glyph_string): Add comments about special meaning
7506 of TAB characters in a composition.
7508 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7510 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7511 This occurs when processing a multibyte format.
7512 Problem reported by Wolfgang Jenker.
7514 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7516 * xdisp.c (try_cursor_movement): Only check for exact match if
7517 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7519 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7521 Remove unused external symbols.
7522 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7523 * xdisp.c (calc_pixel_width_or_height): Now static.
7524 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7525 * indent.c (check_display_width):
7526 * w32term.c: Fix comment to match code.
7527 * xterm.c, xterm.h (x_catching_errors): Remove.
7529 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7531 * xselect.c: Use signed conversions more consistently (Bug#9498).
7532 (selection_data_to_lisp_data): Assume incoming selection data are
7533 signed integers, not unsigned. This is to be consistent with
7534 outgoing selection data, which was modified to use signed integers
7535 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7536 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7537 expects long, not unsigned long.
7539 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7541 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7542 computation of loop end. Reported by Johan Bockgård
7545 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7547 * frame.c (Fother_visible_frames_p): Function deleted.
7549 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7551 * indent.c (compute_motion): Process display vector front to back
7552 rather than the other way around. (Bug#2496)
7554 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7556 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7558 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7560 * minibuf.c (Fread_from_minibuffer): Doc fix.
7562 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7564 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7565 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7567 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7569 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7570 value for non-existent files.
7572 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7574 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7575 set its "size" to -1. This will set the modtime_size field of
7576 the corresponding buffer to -1, which is what
7577 verify-visited-file-modtime expects for files that do not exist.
7580 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7582 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7584 * lisp.h: ... from here. push_key_description is no longer
7585 defined in keyboard.c, so its declaration should not be in
7586 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7587 logically belongs with push_key_description.
7589 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7591 * buffer.h: Include <sys/types.h> instead of <time.h>.
7592 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7593 Problem reported by Herbert J. Skuhra.
7595 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7597 * xml.c (parse_region): Make the parsing work for
7598 non-comment-starting XML files again (bug#9144).
7600 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7602 * image.c (gif_load): Fix calculation of bottom and right corner.
7605 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7607 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7608 redisplay in small windows.
7610 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7612 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7614 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7616 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7617 Operate on live windows only.
7619 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7621 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7623 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7625 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7626 only under bidi iteration.
7628 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7630 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7632 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7634 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7635 Without this fix, the command to link temacs failed due to an
7636 undefined symbol __builtin_isnan. This is because
7637 /usr/include/iso/math_c99.h #defines isnan(x) to
7638 __builtin_isnan(x), but the bundled gcc, which identifies itself
7639 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7641 * floatfns.c (isnan): #undef, and then #define to a clone of
7643 (Fisnan): Always define, since it's always available now.
7644 (syms_of_floatfns): Always define isnan at the Lisp level.
7646 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7648 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7650 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7652 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7653 The previous code assumed that file offsets (off_t values) fit in
7654 EMACS_INT variables, which is not true on typical 32-bit hosts.
7655 The code messed up by falsely reporting buffer overflow in cases
7656 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7657 when "big" contains more than 2**29 bytes, even though this
7658 inserts just one byte and does not overflow the buffer.
7659 (Finsert_file_contents): Store file offsets as off_t
7660 values, not as EMACS_INT values. Check for overflow when
7661 converting between EMACS_INT and off_t. When checking for
7662 buffer overflow or for overlap, take the offsets into account.
7663 Don't use EMACS_INT for small values where int suffices.
7664 When checking for overlap, fix a typo: ZV was used where
7665 ZV_BYTE was intended.
7666 (Fwrite_region): Don't assume off_t fits into 'long'.
7667 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7669 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7671 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7673 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7675 sprintf-related integer and memory overflow issues (Bug#9412).
7677 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7678 (esprintf, exprintf, evxprintf): New functions.
7679 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7680 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7681 (modify_event_symbol): Do not assume that the length of
7682 name_alist_or_stem is safe to alloca and fits in int.
7683 (Fexecute_extended_command): Likewise for function name and binding.
7684 (Frecursion_depth): Wrap around reliably on integer overflow.
7685 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7686 since some callers pass EMACS_INT values.
7687 (Fsingle_key_description): Don't crash if symbol name contains more
7688 than MAX_ALLOCA bytes.
7689 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7690 (get_minibuffer): Arg is now EMACS_INT, not int.
7691 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7692 (esprintf, exprintf, evxprintf): New decls.
7693 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7695 * dbusbind.c (signature_cat): New function.
7696 (xd_signature, Fdbus_register_signal):
7697 Do not overrun buffer; instead, report string overflow.
7699 * dispnew.c (add_window_display_history): Don't overrun buffer.
7700 Truncate instead; this is OK since it's just a log.
7702 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7703 even if the time zone offset is outlandishly large.
7704 Don't mishandle offset == INT_MIN.
7706 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7707 when creating daemon; the previous buffer-overflow check was incorrect.
7709 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7710 which has the guts of the old verror function.
7712 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7713 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7715 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7716 (font_unparse_xlfd): Don't blindly alloca long strings.
7717 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7718 fits in int, when using sprintf. Use single snprintf to count
7719 length of string rather than counting it via multiple sprintfs;
7720 that's simpler and more reliable.
7721 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7722 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7723 sprintf, in case result does not fit in int.
7725 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7726 (fontset_from_font): Print it.
7728 * frame.c (tty_frame_count): Now printmax_t, not int.
7729 (make_terminal_frame, set_term_frame_name): Print it.
7730 (x_report_frame_params): In X, window IDs are unsigned long,
7731 not signed long, so print them as unsigned.
7732 (validate_x_resource_name): Check for implausibly long names,
7733 and don't assume name length fits in 'int'.
7734 (x_get_resource_string): Don't blindly alloca invocation name;
7735 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7738 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7739 (xg_check_special_colors, xg_set_geometry):
7740 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7742 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7743 Use esprintf, not sprintf, in case result does not fit in int.
7745 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7746 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7747 it as a large positive number.
7748 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7749 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7751 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7752 in case result does not fit in int.
7754 * print.c (float_to_string): Detect width overflow more reliably.
7755 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7756 buffer overrun. Don't assume list length fits in 'int'. Treat
7757 print length of 0 as 0, not as infinity; to be consistent with other
7758 uses of print length in this function. Don't overflow print length
7759 index. Don't assume hash table size fits in 'long', or that
7760 vectorlike size fits in 'unsigned long'.
7762 * process.c (make_process): Use printmax_t, not int, to format
7763 process-name gensyms.
7765 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7767 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7768 to avoid potential buffer overrun.
7770 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7771 if X resource line is longer than 512 bytes.
7773 * xfns.c (x_window): Make sprintf buffer a bit bigger
7774 to avoid potential buffer overrun.
7776 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7780 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7782 Integer overflow fixes for scrolling, etc.
7783 Without these, Emacs silently mishandles large integers sometimes.
7784 For example, "C-u 4294967297 M-x recenter" was treated as if
7785 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7787 * xdisp.c (try_window_id): Check Emacs fixnum range before
7788 converting to 'int'.
7790 * window.c (window_scroll_line_based, Frecenter):
7791 Check that an Emacs fixnum is in range before assigning it to 'int'.
7792 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7793 values converted from Emacs fixnums.
7794 (Frecenter): Don't wrap around a line count if it is out of 'int'
7795 range; instead, treat it as an extreme value.
7796 (Fset_window_configuration, compare_window_configurations):
7797 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7799 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7800 that can exceed INT_MAX. Check that EMACS_INT value is in range
7801 before assigning it to the (possibly-narrower) index.
7802 (match_limit): Don't assume that a fixnum can fit in 'int'.
7804 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7807 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7808 (Fvertical_motion): Don't wrap around LINES values that don't fit
7809 in 'int'. Instead, treat them as extreme values. This is good
7810 enough for windows, which can't have more than INT_MAX lines anyway.
7812 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7814 * Require libxml/parser.h to avoid compilation warning.
7816 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7818 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7819 since this reportedly can destroy thread storage.
7821 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7823 * syntax.c (find_defun_start): Update all cache variables if
7824 exiting early (Bug#9401).
7826 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7828 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7830 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7831 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7832 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7834 * term.c (tty_append_glyph): New function.
7835 (produce_stretch_glyph): Static function and its prototype deleted.
7837 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7840 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7842 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7843 when checking :margin (Bug#9390).
7844 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7845 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7846 so that the name doesn't mislead. All uses changed.
7848 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7850 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7853 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7855 * xdisp.c (move_it_to): Don't bail out early when reaching
7856 position beyond to_charpos, if we are scanning backwards.
7857 (move_it_vertically_backward): When DY == 0, make sure we get to
7858 the first character in the line after the newline.
7860 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7862 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7863 (ccl_driver): Do not generate an out-of-range pointer.
7864 (Fccl_execute_on_string): Remove unnecessary check for
7865 integer overflow, noted by Stefan Monnier in
7866 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7867 Remove a FIXME that didn't need fixing.
7868 Simplify the newly-introduced buffer reallocation code.
7870 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7872 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7874 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7876 Integer and memory overflow issues (Bug#9196).
7878 * doc.c (get_doc_string): Rework so that
7879 get_doc_string_buffer_size is the actual buffer size, rather than
7880 being 1 less than the actual buffer size; this makes xpalloc more
7883 * image.c (x_allocate_bitmap_record, cache_image):
7884 * xselect.c (Fx_register_dnd_atom):
7885 Simplify previous changes by using xpalloc.
7887 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7888 since either will do and ptrdiff_t is convenient with xpalloc.
7890 * charset.c (charset_table_size)
7891 (struct charset_sort_data.priority): Now ptrdiff_t.
7892 (charset_compare): Don't overflow if priorities differ greatly.
7893 (Fsort_charsets): Don't assume list length fits in int.
7894 Check for size-calculation overflow when allocating sort data.
7895 (syms_of_charset): Allocate an initial charset table that is
7896 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7898 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7900 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7901 The actual value is always <= INT_MAX, and leaving it unsigned made
7902 overflow checking harder.
7904 * dispextern.h (struct glyph_matrix.rows_allocated)
7905 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7906 with xpalloc. The values are still always <= INT_MAX.
7908 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7910 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7911 (SAFE_NALLOCA): New macro.
7913 * region-cache.c (struct boundary.pos, find_cache_boundary)
7914 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7915 (set_cache_region, invalidate_region_cache)
7916 (revalidate_region_cache, know_region_cache, region_cache_forward)
7917 (region_cache_backward, pp_cache):
7918 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7919 so that ptrdiff_t * can be passed to xpalloc.
7920 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7921 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7922 (pp_cache): Don't assume cache_len fits in int.
7923 * region-cache.h: Adjust extern decls to match.
7925 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7926 EMACS_INT, since either will do, for xpalloc.
7928 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7929 (xnmalloc, xnrealloc, xpalloc): New functions.
7931 * bidi.c (bidi_shelve_header_size): New constant.
7932 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7933 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7935 * bidi.c (bidi_cache_shrink):
7936 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7938 Don't update size of array until after memory allocation succeeds,
7939 because xmalloc/xrealloc may not return.
7940 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7941 now that we have proper integer overflow checking.
7942 (record_overlay_string, overlay_strings): Catch overflows when
7943 calculating size of overlay_str_buf.
7945 * callproc.c (Fcall_process): Check for size overflow when
7946 calculating size of args2.
7947 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7948 Normally we prefer signed values, but sticking with ptrdiff_t would
7949 require adding more-complicated checks.
7951 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7952 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7953 Redo buffer-overflow calculations to avoid integer overflow.
7954 Add a FIXME comment where memory seems to be over-allocated.
7956 * character.c (Fstring): Check for size-calculation overflow.
7958 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7959 unnecessary integer overflow. Check for size overflow.
7960 (encode_coding_object): Don't update size until xmalloc succeeds.
7962 * composite.c (get_composition_id): Check for overflow in glyph
7963 length calculations.
7965 Integer and memory overflow fixes for display code.
7966 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7967 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7968 (scrolling_window): Check for overflow in size calculations.
7969 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7973 (scrolling_window): Avoid overflow in size calculations.
7974 Don't update size until allocation succeeds.

7980 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7981 (get_doc_string): Check for size calculation overflow.
7982 Don't update size until allocation succeeds.
7983 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7984 EMACS_INT, where ptrdiff_t will do.
7985 (Fsubstitute_command_keys): Check for string overflow.
7987 * editfns.c (set_time_zone_rule): Don't assume environment length
7989 (message_length): Now ptrdiff_t, not int.
7990 (Fmessage_box): Don't update size until allocation succeeds.
7991 Don't assume message length fits in int.
7992 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7994 * emacs.c (main): Do not reallocate argv, since there is a null at
7995 the end that can be overwritten, and this way there's no need to
7996 worry about size-calculation overflow.
7997 (sort_args): Check for size-calculation overflow.
7999 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8001 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8003 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8004 (x_set_scroll_bar_width, x_figure_window_size):
8005 Check for integer overflow.
8006 (x_set_alpha): Do not assume XINT fits in int.
8008 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8009 This is for the members text_lines, text_cols, total_lines, total_cols,
8010 where the system imposes an 'int' limit.
8012 * fringe.c (Fdefine_fringe_bitmap):
8013 Don't update size until alloc works.
8015 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8016 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8018 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8019 Check for size-calculation overflow.
8020 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8021 do, as we prefer signed integers.
8022 (id_to_widget.max_size, id_to_widget.used)
8023 (xg_store_widget_in_map, xg_remove_widget_from_map)
8024 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8025 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8026 Use and return ptrdiff_t, not int.
8027 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8028 * gtkutil.h: Change prototypes to match the above.
8030 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8031 are duplicate now that they've been promoted to lisp.h.
8032 (x_allocate_bitmap_record, x_alloc_image_color)
8033 (make_image_cache, cache_image, xpm_load):
8034 Don't update size until alloc is done.
8035 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8037 Check for size calculation overflow.
8038 (ct_colors_allocated_max): New constant.
8039 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

8044 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8045 Use ptrdiff_t, not int, to count maps.
8046 (read_char_minibuf_menu_prompt): Check for overflow in size
8047 calculations. Don't update size until allocation succeeds.

8059 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8061 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8062 Now ptrdiff_t, not int.
8063 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

8074 * search.c (Freplace_match): Check for size calculation overflow.
8075 (Fset_match_data): Don't assume list lengths fit in 'int'.
8077 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8078 for command line length. Do not attempt to address one before the
8079 beginning of an array, as that's not portable.

8082 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8084 (encode_terminal_code, calculate_costs): Check for size
8085 calculation overflow.

8087 table lengths and related sizes. Don't update size until alloc
8088 done. Redo calculations to avoid overflow.
8089 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8091 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

8107 Use ptrdiff_t, not int, for sizes.
8108 (Finternal_make_lisp_face, cache_face):
8109 Check for size calculation overflow.
8110 (cache_face): Treat size calculation overflows as if they were
8111 memory exhaustion (the usual treatment), rather than aborting.
8113 * xfns.c (x_encode_text, x_set_name_internal)
8114 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8115 sizes, since they can exceed INT_MAX in size. Check for size
8116 calculation overflow.
8118 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8119 (xg_select): Check for size calculation overflow.
8120 Don't update size until alloc done.
8122 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8123 as sprintf is limited to int lengths.
8125 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8126 (X_LONG_MIN): New macros.
8127 Use them to make the following changes clearer.
8128 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8129 This change doesn't affect the value now, but it may help remind
8130 future maintainers not to raise the value too much later.
8131 (SELECTION_QUANTUM): Remove, replacing with ...
8132 (selection_quantum): ... new function, which avoids overflow.
8134 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8135 assumption that selection length fits in 'int'.
8136 (x_reply_selection_request, x_handle_selection_request)
8137 (x_get_window_property, receive_incremental_selection)
8138 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8139 (lisp_data_to_selection_data, clean_local_selection_data):
8140 Use ptrdiff_t, not int, to record length of selection.
8141 (x_reply_selection_request, x_get_window_property)
8142 (receive_incremental_selection, x_property_data_to_lisp):
8143 Redo calculations to avoid overflow.
8144 (x_reply_selection_request): When sending hint, ceiling it at
8145 X_LONG_MAX rather than relying on wraparound overflow to send
8147 (x_get_window_property, receive_incremental_selection)
8148 (lisp_data_to_selection_data, x_property_data_to_lisp):
8149 Check for size-calculation overflow.
8150 (x_get_window_property, receive_incremental_selection)
8151 (lisp_data_to_selection_data, Fx_register_dnd_atom):
8152 Don't store size until memory allocation succeeds.
8153 (x_get_window_property): Plug memory leak on memory exhaustion.
8154 Don't double-block input; malloc is safe here. Don't assume 2**34
8155 - 4 fits in unsigned long. Add an xassert to check
8156 XGetWindowProperty overflow. Be more careful about overflow
8157 calculations, and distinguish size from memory overflow better.
8158 (receive_incremental_selection): When tracing, don't assume
8159 unsigned int is less than INT_MAX.
8160 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8161 harmful) conversions of unsigned short to int.
8162 (lisp_data_to_selection_data): Don't assume that integers
8163 in the range -65535 through -1 fit in an X unsigned short.
8164 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8165 result parameters unless successful. Rely on cons_to_unsigned
8166 to report problems with elements; the old code wasn't right anyway.
8167 (x_check_property_data): Check for int overflow; we cannot use
8168 a wider type due to X limits.
8169 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8201 * lisp.h (hash_lookup, hash_put):
8202 * minibuf.c (Ftest_completion):
8203 Use ptrdiff_t for hash table indexes, not int (which is too
8204 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8205 32-bit --with-wide-int hosts).
8207 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8208 Add a FIXME comment about memory leaks.
8209 (syms_of_charset): Don't assume xmalloc returns.
8211 Don't assume that stated character widths fit in int.

8213 * character.h (CHAR_WIDTH):
8214 * indent.c (MULTIBYTE_BYTES_WIDTH):
8215 Use sanitize_char_width to avoid undefined and/or bad behavior
8216 with outlandish widths.
8217 * character.h (sanitize_tab_width): Rename from sanitize_width,
8218 now that we have two such functions. All uses changed.
8219 (sanitize_char_width): New inline function.

8237 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8238 (x_send_scroll_bar_event): Likewise. Check that the size does not
8239 exceed limits imposed by XClientMessageEvent, as well as the usual
8240 ptrdiff_t and size_t limits.
8242 * keyboard.c: Overflow, signedness and related fixes.
8243 (make_lispy_movement): Use same integer type in forward decl
8244 that is used in the definition.
8245 (read_key_sequence, keyremap_step):
8246 Change bufsize argument back to int, undoing my 2011-03-30 change.
8247 We prefer signed types, and int is wide enough here.
8248 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8249 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8250 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8251 length, not size_t. Use ptrdiff_t for index, not int.
8252 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8253 possibility of integer overflow.
8255 Overflow, signedness and related fixes for images.

8276 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8277 (lookup_image): Remove unnecessary tests.
8278 (xbm_image_p): Locals are now of int, not EMACS_INT,
8279 since parse_image_check makes sure they fit into int.
8280 (png_load, gif_load, svg_load_image):
8281 Prefer int to unsigned where either will do.
8282 (tiff_handler): New function, combining the cores of the
8283 old tiff_error_handler and tiff_warning_handler.
8284 This function is rewritten to use vsnprintf and thereby avoid
8285 stack buffer overflows. It uses only the features of vsnprintf
8286 that are common to both POSIX and native Microsoft.
8287 (tiff_error_handler, tiff_warning_handler): Use it.
8288 (tiff_load, gif_load, imagemagick_load_image):
8289 Don't assume :index value fits in 'int'.
8290 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8291 (imagemagick_load_image): Check that crop parameters fit into
8292 the integer types that MagickCropImage accepts. Don't assume
8293 Vimagemagick_render_type has a nonnegative value. Don't assume
8294 size_t fits in 'long'.
8295 (gs_load): Use printmax_t to print the widest integers possible.

8306 the display spec is of the form `(space ...)'.
8307 (handle_display_spec): Return the value returned by
8308 handle_single_display_spec, not just 1 or zero.
8309 (handle_single_display_spec): If the display spec is of the form
8310 `(space ...)', and specifies display in the text area, return 2
8312 (try_cursor_movement): Check for the need to scroll more
8313 accurately, and prefer exact match for point under bidi.
8314 Don't advance `row' beyond the last row of the window.
8316 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8317 into disp_prop; all users changed.
8319 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8332 buffers, return left-to-right.
8333 (set_cursor_from_row): Consider candidate row a win if its glyph
8334 represents a newline and point is on that newline. Fixes cursor
8335 positioning on the newline at EOL of R2L text within L2R
8336 paragraph, and vice versa.
8337 (try_cursor_movement): Check continued rows, in addition to
8338 continuation rows. Fixes unwarranted scroll when point enters a
8339 continued line of R2L text within an L2R paragraph, or vice versa.
8340 (cursor_row_p): Consider the case of point being equal to
8341 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8342 from the end of a short line to the beginning of a continued line
8343 of R2L text within L2R paragraph.
8344 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8345 composed characters.
8347 * bidi.c (bidi_check_type): Use xassert.

8360 2011-08-22 Kenichi Handa <handa@m17n.org>
8362 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8363 extra slot even if the purpose is char-code-property-table.
8365 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8367 * xdisp.c (redisplay_window): When computing centering_position,
8368 account for the height of the header line. (Bug#8874)
8370 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8371 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8372 candidate is selected by the mouse, and that candidate has a
8373 composed character under the mouse.
8375 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8376 coordinates reported by pos-visible-in-window-p for a composed
8377 character in column zero.

8383 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8385 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8386 consider it a hit if to_charpos is anywhere in the range of the
8387 composed buffer positions.
8389 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8391 * image.c (gif_load): Don't assume that each subimage has the same
8392 dimensions as the base image. Handle disposal method that is
8393 "undefined" by the gif spec (Bug#9335).
8395 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8397 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8400 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8402 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8403 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8404 from an Org mode buffer to a Speedbar frame.
8406 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8407 a composition, take its buffer position from IT->cmp_it.charpos.
8408 Fixes cursor positioning at the beginning of a line that begins
8409 with a composed character.
8411 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8413 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8414 character bidirectional type, use STRONG_L instead. Fixes crashes
8415 in a buffer produced by `describe-categories'.
8417 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8418 members before the level stack, so they would be saved and
8419 restored when copying iterator state. Fixes incorrect reordering
8420 around TABs covered by display properties.
8422 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8424 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8432 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8434 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8435 has no `load' handler, try opening the file locally. (Bug#9311)
8437 2011-08-16 Ken Brown <kbrown@cornell.edu>

8494 * xdisp.c (move_it_in_display_line_to): Don't invoke
8495 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8496 ppos_it. Fixes vertical cursor motion when line beginning is
8497 covered by an image. (Bug#9296)
8499 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8501 * nsterm.h (ns_run_ascript): Declare.

8504 * nsfns.m (as_script, as_result, as_status): New static variables.
8505 (ns_run_ascript): New function.
8506 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8507 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8508 the event loop. Get status from as_status (Bug#7276).
8510 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8511 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8512 the event loop (Bug#7276).

8537 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8538 (Fnetwork_interface_list): Allocate in increments of bytes instead
8539 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8540 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8542 (struct ifflag_def): notrailers is smart on OSX.
8543 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8544 Get hardware address with getifaddrs if available.
8546 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8548 * xdisp.c (iterate_out_of_display_property): xassert that
8549 IT->position is set to within IT->object's boundaries. Break from
8550 the loop as soon as EOB is reached; avoids infloops in redisplay
8551 when IT->position is set up wrongly due to some bug.
8552 Set IT->current to match the bidi iterator unconditionally.
8553 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8554 entry. Force push_it to save on the stack the current
8555 buffer/string position, to be restored by pop_it. Fix flags in
8556 the iterator structure wrt the object coming from a display
8557 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8558 properties. (Bug#9284)
8560 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8562 * fontset.c (fontset_get_font_group): Add proper type checks.

8570 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8572 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8574 * xdisp.c (forward_to_next_line_start): Allow to use the
8575 no-display-properties-and-no-overlays under bidi display.
8576 Set disp_pos in the bidi iterator to avoid searches for display
8577 properties and overlays.
8579 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8581 * editfns.c (Fset_time_zone_rule): Document relationship with the

8587 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8589 * composite.c (autocmp_chars): Don't reset point. That is done by
8590 restore_point_unwind (Bug#5984).
8592 2011-08-07 Juri Linkov <juri@jurta.org>
8594 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8595 to show the arg `TIME' instead of `TIMEVAL'.
8597 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8599 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8600 display property strides EOL and includes a newline, as in
8601 longlines-mode. (Bug#9254)
8602 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8603 word-wrap under bidirectional display. (Bug#9224)
8605 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8606 is non-zero, even if the data buffer is NULL. Fixes a crash in
8607 vertical-motion with longlines-mode. (Bug#9254)
8609 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8611 * bidi.c <bidi_cache_total_alloc>: Now static.
8612 (bidi_initialize): Initialize bidi_cache_total_alloc.
8614 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8617 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8618 amount allocated this far in `bidi_cache_total_alloc'.
8619 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8620 non-zero, only free the data buffer without restoring the cache
8621 contents. All callers changed.
8623 * dispextern.h (bidi_unshelve_cache): Update prototype.
8625 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8626 (move_it_in_display_line, move_it_to)
8627 (move_it_vertically_backward, move_it_by_lines): Replace the call
8628 to xfree to an equivalent call to bidi_unshelve_cache.
8629 (move_it_in_display_line_to): Fix logic of returning
8630 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8632 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8634 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8635 came from a string character with a `cursor' property. (Bug#9229)

8654 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8656 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8658 * callproc.c (Fcall_process): Avoid vfork clobbering
8659 the local vars buffer, coding_systems, current_dir.
8661 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8663 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8665 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8667 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8668 so that it is not optimized away.
8670 * xdisp.c (compute_display_string_pos): Remove unused local.
8672 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8674 Fix slow cursor motion and scrolling in large buffers with
8675 selective display, like Org Mode buffers. (Bug#9218)
8677 * dispextern.h (struct bidi_it): New member disp_prop_p.
8679 * xdisp.c: Remove one-slot cache of display string positions.
8680 (compute_display_string_pos): Accept an additional argument
8681 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8682 for a display string or property. If found, set DISP_PROP_P
8685 * bidi.c (bidi_fetch_char): Accept an additional argument
8686 DISP_PROP_P, and pass it to compute_display_string_pos.
8687 Only handle text covered by a display string if DISP_PROP_P is returned
8688 non-zero. All callers of bidi_fetch_char changed.
8690 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8692 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8694 2010-12-03 Don March <don@ohspite.net>
8696 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8697 last character M-[char] is translated to ESC [char] (bug#7541).
8699 2011-08-02 Kenichi Handa <handa@m17n.org>
8701 * lisp.h (uniprop_table): Extern it.
8703 * chartab.c (uniprop_table): Make it non-static.
8705 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8707 * xdisp.c (forward_to_next_line_start): Accept additional argument
8708 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8710 (reseat_at_next_visible_line_start): Use the bidi iterator state
8711 returned by forward_to_next_line_start to restore the state of
8712 it->bidi_it after backing up to previous newline. (Bug#9212)
8714 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8716 * regex.c (re_comp): Protoize.
8717 (re_exec): Fix return type.
8718 (regexec): Fix type of `ret'. (Bug#9203)
8720 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8722 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8723 This is needed if max-image-size is a floating-point number.
8725 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8727 * print.c (print_object): Print empty symbol as ##.
8729 * lread.c (read1): Read ## as empty symbol.
8731 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8733 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8734 setting frame foreground color (Bug#9175).
8735 (x_set_background_color): Likewise.
8737 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8738 contents (Bug#9176).
8739 (EmacsTooltip -init): Remove bezels and add shadows to
8742 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8743 or scroll bar (Bug#8470).
8745 * nsfont.m (nsfont_open): Remove assignment to voffset and
8746 unnecessary vars hshink, expand, hd, full_height, min_height.
8747 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8749 * nsterm.h (nsfont_info): Remove voffset field.
8751 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8753 Implement strike-through and overline on NextStep (Bug#8863).
8755 * nsfont.m (nsfont_open): Use underline position provided by font,
8756 instead of hard-coded value of 2.
8757 (nsfont_draw): Call ns_draw_text_decoration instead.
8759 * nsterm.h: Add declaration for ns_draw_text_decoration.
8761 * nsterm.m (ns_draw_text_decoration): New function for drawing
8762 underline, overline, and strike-through.
8763 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8764 ns_draw_text_decoration. Change treatment of cursor drawing to
8765 accommodate underlining, etc.
8767 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8769 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8772 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8774 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8775 Without this fix, if a signal arrives just after memory fills up,
8776 'malloc' might be invoked reentrantly.
8778 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8779 In other words, assume that every image size is allowed, on non-X
8780 hosts. This assumption is probably wrong, but it lets Emacs compile.
8782 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8784 * regex.c (re_iswctype): Convert return values to boolean.
8786 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8788 * xdisp.c (compute_display_string_pos): Don't use cached display
8789 string position if the buffer had its restriction changed.
8792 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8794 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8796 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8798 Integer signedness and overflow and related fixes. (Bug#9079)
8800 * bidi.c: Integer size and overflow fixes.
8801 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8802 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8803 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8804 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8805 (bidi_find_other_level_edge):
8806 Use ptrdiff_t instead of EMACS_INT where either will do.
8807 This works better on 32-bit hosts configured --with-wide-int.
8808 (bidi_cache_ensure_space): Check for size-calculation overflow.
8809 Use % rather than repeated addition, for better worst-case speed.
8810 Don't set bidi_cache_size until after xrealloc returns, because it
8812 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8813 (bidi_cache_ensure_space): Also check that the bidi cache size
8814 does not exceed that of the largest Lisp string or buffer. See Eli
8815 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8817 * alloc.c (__malloc_size_t): Remove.
8818 All uses replaced by size_t. See Andreas Schwab's note
8819 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8821 * image.c: Improve checking for integer overflow.
8822 (check_image_size): Assume that f is nonnull, since
8823 it is always nonnull in practice. This is one less thing to
8824 worry about when checking for integer overflow later.
8825 (x_check_image_size): New function, which checks for integer
8826 overflow issues inside X.
8827 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8828 This removes the need for a memory_full check.
8829 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8830 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8831 (xbm_read_bitmap_data): Change locals back to 'int', since
8832 their values must fit in 'int'.
8833 (xpm_load_image, png_load, tiff_load):
8834 Invoke x_create_x_image_and_pixmap earlier,
8835 to avoid much needless work if the image is too large.
8836 (tiff_load): Treat overly large images as if
8837 x_create_x_image_and_pixmap failed, not as malloc failures.
8838 (gs_load): Use x_check_image_size.
8840 * gtkutil.c: Omit integer casts.
8841 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8842 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8844 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8846 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8847 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8848 would wrongly return t on a 64-bit host.
8850 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8851 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8852 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8853 and therefore cause GCC to emit a bogus diagnostic in some cases.
8855 * image.c: Integer signedness and overflow and related fixes.
8856 This is not an exhaustive set of fixes, but it's time to
8857 record what I've got.
8858 (lookup_pixel_color, check_image_size): Remove redundant decls.
8859 (check_image_size): Don't assume that arbitrary EMACS_INT values
8860 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8861 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8862 (tiff_load, imagemagick_load_image):
8863 Check for overflow in size calculations.
8864 (x_create_x_image_and_pixmap): Remove unnecessary test for
8865 xmalloc returning NULL; that can't happen.
8866 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8867 (xpm_color_bucket): Use better integer hashing function.
8868 (xpm_cache_color): Don't possibly over-allocate memory.
8869 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8870 (gif_memory_source):
8871 Use ptrdiff_t, not int or size_t, to record sizes.
8872 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8873 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8874 either works, as we prefer signed integers.
8875 (tiff_read_from_memory, tiff_write_from_memory):
8876 Return tsize_t, not size_t, since that's what the TIFF API wants.
8877 (tiff_read_from_memory): Don't fail simply because the read would
8878 go past EOF; instead, return a short read.
8879 (tiff_load): Omit no-longer-needed casts.
8880 (Fimagemagick_types): Don't assume size fits into 'int'.
8882 Improve hashing quality when configured --with-wide-int.
8883 * fns.c (hash_string): New function, taken from sxhash_string.
8884 Do not discard information about ASCII character case; this
8885 discarding is no longer needed.
8886 (sxhash-string): Use it. Change sig to match it. Caller changed.
8887 * lisp.h: Declare it.
8888 * lread.c (hash_string): Remove, since we now use fns.c's version.
8889 The fns.c version returns a wider integer if --with-wide-int is
8890 specified, so this should help the quality of the hashing a bit.
8892 * emacs.c: Integer overflow minor fix.
8893 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8894 Define only if GNU_LINUX.
8895 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8897 * dispnew.c: Integer signedness and overflow fixes.
8898 Remove unnecessary forward decls, that were a maintenance hassle.
8899 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8901 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8902 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8903 (prepare_desired_row, line_draw_cost):
8904 Use int, not unsigned, where either works.
8905 (save_current_matrix, restore_current_matrix):
8906 Use ptrdiff_t, not size_t, where either works.
8907 (init_display): Check for overflow more accurately, and without
8908 relying on undefined behavior.
8910 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8911 Remove, replacing with the new symbols in lisp.h. All uses changed.
8912 * fileio.c (make_temp_name):
8913 * filelock.c (lock_file_1, lock_file):
8914 * xdisp.c (message_dolog):
8915 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8916 Use pMd etc. instead.
8917 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8918 replacing the pWIDE etc. symbols removed from editfns.c.
8920 * keyboard.h (num_input_events): Now uintmax_t.
8921 This is (very slightly) less likely to mess up due to wraparound.
8924 * buffer.c: Integer signedness fixes.
8925 (alloc_buffer_text, enlarge_buffer_text):
8926 Use ptrdiff_t rather than size_t when either will do, as we prefer
8929 * alloc.c: Integer signedness and overflow fixes.
8930 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8931 (__malloc_size_t): Default to size_t, not to int.
8932 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8933 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8934 Prefer ptrdiff_t to size_t when either would do, as we prefer
8936 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8937 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8938 Now const. Initialize with values that are in range even if char
8940 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8941 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8942 These functions do the right thing with sizes > 2**32.
8943 (check_depth): Now ptrdiff_t, not int.
8944 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8945 Adjust to new way of storing sizes. Check for size overflow bugs
8947 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8948 slightly wrong anyway, as it missed one instance of
8949 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8950 (refill_memory_reserve): Omit needless cast to size_t.
8951 (mark_object_loop_halt): Mark as externally visible.
8953 * xselect.c: Integer signedness and overflow fixes.
8954 (Fx_register_dnd_atom, x_handle_dnd_message):
8955 Use ptrdiff_t, not size_t, since we prefer signed.
8956 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8957 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8958 x_dnd_atoms_size and x_dnd_atoms_length.
8960 * doprnt.c: Prefer signed to unsigned when either works.
8962 * doprnt.c (doprnt):
8964 * xdisp.c (vmessage):
8965 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8966 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8967 prefer signed arithmetic to avoid comparison confusion.
8968 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8969 but is a bit tricky.
8971 Assume freestanding C89 headers, string.h, stdlib.h.
8972 * data.c, doprnt.c, floatfns.c, print.c:
8973 Include float.h unconditionally.
8974 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8975 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8976 * regex.c: Likewise for stddef.h, string.h.
8977 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8978 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8979 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8980 (STDC_HEADERS): Remove obsolete defines.
8981 * sysdep.c: Include limits.h unconditionally.
8983 Assume support for memcmp, memcpy, memmove, memset.
8984 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8985 * regex.c (memcmp, memcpy):
8986 Remove; we assume C89 now.
8988 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8989 (__malloc_safe_bcopy): Remove; no longer needed.
8991 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8992 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8993 well either way, and we prefer signed to unsigned.
8995 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8997 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8998 closes the connection while we're reading (bug#9182).
9000 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9002 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9003 are specified (Bug#9168).
9005 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9007 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9008 Found by GCC static checking and --with-wide-int on a 32-bit host.
9010 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9012 * xdisp.c (compute_display_string_pos): Fix logic of caching
9013 previous display string position. Initialize cached_prev_pos to
9014 -1. Fixes slow-down at the beginning of a buffer.
9016 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9018 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9019 for attrs[LFACE_FONTSET_INDEX].
9021 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9023 * xml.c (parse_region): Remove unused local
9024 that was recently introduced.
9026 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9028 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9029 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9031 * xdisp.c (move_it_in_display_line_to): Record the best matching
9032 position for TO_CHARPOS while scanning the line, and restore it on
9033 exit if none of the characters scanned was an exact match.
9034 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9035 when exact match is impossible due to invisible text, and the
9036 lines are truncated.
9038 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9040 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9043 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9045 Fix a significant slow-down of cursor motion with C-n, C-p,
9046 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9047 auto-repeat under bidi redisplay in fontified buffers.
9048 * xdisp.c (compute_stop_pos_backwards): New function.
9049 (next_element_from_buffer): Call compute_stop_pos_backwards to
9050 find a suitable prev_stop when we find ourselves before
9052 (reseat): Don't look for prev_stop, as that could mean a very long
9054 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9055 <cached_disp_overlay_modiff>: Cache for last found display string
9057 (compute_display_string_pos): Return the cached position if asked
9058 about the same buffer in the same area of character positions, and
9059 the buffer wasn't changed since the time the display string
9060 position was cached.
9062 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9064 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9065 is an integer, which is important for empty lines. (Bug#9149)
9067 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9069 * frame.c (Fmodify_frame_parameters): In tty case, update the
9070 default face if necessary (Bug#4238).
9072 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9074 * editfns.c (Fstring_to_char): No need to explain what a character
9075 is in the docstring (Bug#6576).
9077 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9079 * xml.c (parse_region): Make sure we always return a tree.
9081 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9083 * xml.c (parse_region): If a document contains only comments,
9086 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9088 * xml.c (make_dom): Return comments, too.
9090 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9093 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9094 and the surrounding thread.
9095 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9096 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9097 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9099 * s/openbsd.h (BROKEN_SIGIO): Define.
9100 * unexelf.c (unexec) [__OpenBSD__]:
9101 Don't update the .mdebug section of the Alpha COFF symbol table.
9103 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9105 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9108 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9110 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9111 This fixes some race conditions on the permissions of any newly
9114 * alloc.c (valid_pointer_p): Use pipe, not open.
9115 This fixes some permissions issues when debugging.
9117 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9118 If fchown fails to set both uid and gid, try to set just gid,
9119 as that is sometimes allowed. Adjust the file's mode to eliminate
9120 setuid or setgid bits that are inappropriate if fchown fails.

9140 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9141 This works around a problem with the previous change to Fcopy_file.
9142 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9143 and without this change, GCC might complain about discarding
9144 fchown's return value.
9146 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9148 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

9189 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9190 (elsz): Now a signed constant, not a size_t var. We prefer signed
9191 types to unsigned, to avoid integer comparison confusion. Without
9192 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9193 "cannot optimize loop, the loop counter may overflow", a symptom
9195 * indent.c (Fvertical_motion): Mark locals as initialized.
9196 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9198 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9200 * search.c (Fre_search_backward): Mention `case-fold-search' in
9201 all the re_search_* functions (bug#8138).

9242 the iterator is before prev_stop.
9243 (init_iterator): Initialize bidi_p from the default value of
9244 bidi-display-reordering, not from buffer-local value. Use the
9245 buffer-local value only if initializing for buffer iteration.

9761 Random fixes. E.g., (random) never returned negative values.
9762 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9763 subseconds part to the entropy, as that's a bit more random.
9764 Prefer signed to unsigned, since the signedness doesn't matter and
9765 in general we prefer signed. When given a limit, use a
9766 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9767 latter isn't right if USE_2_TAGS_FOR_INTS.
9768 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9769 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9782 This is more efficient than Ffile_directory_p and avoids a minor race.
9784 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9786 * buffer.c (Foverlay_put): Say what the return value is
9789 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9793 error be more correct.
9795 * fns.c (Frequire): Remove the mention of the .gz files, since
9796 that's installation-specific, but keep the mention of

9914 * eval.c (struct backtrace): Simplify and port the data structure.
9915 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9916 signed bit field, as this assumption is not portable and it makes
9917 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9918 "char debug_on_exit : 1" as this is not portable either; instead,
9919 use the portable "unsigned int debug_on_exit : 1". Remove unused

10084 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10086 Integer and buffer overflow fixes (Bug#8873).
10088 * print.c (printchar, strout): Check for string overflow.
10089 (PRINTPREPARE, printchar, strout):
10090 Don't set size unless allocation succeeds.
10092 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10093 for sizes. Check for string overflow more accurately.
10094 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10096 * macros.c: Integer and buffer overflow fixes.
10097 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10098 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10099 Use ptrdiff_t, not int, for sizes.
10100 Don't increment bufsize until after realloc succeeds.
10101 Check for size-calculation overflow.
10102 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10104 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10106 * lread.c: Integer overflow fixes.
10107 (read_integer): Radix is now EMACS_INT, not int,
10108 to improve quality of diagnostics for out-of-range radices.
10109 Calculate buffer size correctly for out-of-range radices.
10110 (read1): Check for integer overflow in radices, and in
10111 read-circle numbers.
10112 (read_escape): Avoid int overflow.
10113 (Fload, openp, read_buffer_size, read1)
10114 (substitute_object_recurse, read_vector, read_list, map_obarray):
10115 Use ptrdiff_t, not int, for sizes.
10116 (read1): Use EMACS_INT, not int, for sizes.
10117 Check for size overflow.
10119 * image.c (cache_image): Check for size arithmetic overflow.
10121 * lread.c: Integer overflow issues.
10122 (saved_doc_string_size, saved_doc_string_length)
10123 (prev_saved_doc_string_size, prev_saved_doc_string_length):
10124 Now ptrdiff_t, not int.
10125 (read1): Don't assume doc string length fits in int. Check for
10126 out-of-range doc string lengths.
10127 (read_list): Don't assume file position fits in int.
10128 (read_escape): Check for hex character overflow.
10130 2011-06-22 Leo Liu <sdl.web@gmail.com>
10132 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10133 Move to minibuffer.el.
10135 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10137 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10138 The following patches are for when GLYPH_DEBUG && !XASSERT.
10139 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10140 * dispnew.c (flush_stdout):
10141 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10142 Mark as externally visible.
10143 * dispnew.c (check_window_matrix_pointers): Now static.
10144 * dispnew.c (window_to_frame_vpos):
10145 * xfns.c (unwind_create_frame):
10146 * xterm.c (x_check_font): Remove unused local.
10147 * scroll.c (CHECK_BOUNDS):
10148 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10149 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10150 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10151 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10152 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10154 (debug_method_add): Use va_list and vsprintf rather than relying
10155 on undefined behavior with wrong number of arguments.
10156 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10157 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10158 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10159 since we're not interested in debugging glyphs with old libraries.
10160 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10161 GCC 4.6.0's static checking.
10163 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10165 Integer overflow and signedness fixes (Bug#8873).

10174 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10175 (x_create_bitmap_from_xpm_data):
10176 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10177 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10179 * xfaces.c (load_pixmap):
10180 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10181 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10182 (.bitmaps_last, struct x_output.icon_bitmap):
10183 Use ptrdiff_t, not int, for bitmap indexes.
10184 (x_allocate_bitmap_record): Check for size overflow.
10185 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10187 Use ptrdiff_t, not int, for overlay counts.
10188 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10189 * editfns.c (overlays_around, get_pos_property):
10190 * textprop.c (get_char_property_and_overlay):
10191 * xdisp.c (next_overlay_change, note_mouse_highlight):
10192 * xfaces.c (face_at_buffer_position):
10193 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10194 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10195 (Fnext_overlay_change, Fprevious_overlay_change)
10196 (mouse_face_overlay_overlaps, Foverlays_in):
10197 Use ptrdiff_t, not int, for sizes.
10198 (overlays_at, overlays_in): Check for size-calculation overflow.
10200 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10202 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10203 (x_session_initialize): Do not assume string length fits in int.
10205 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10206 This is unlikely, but can occur if DPI is outlandish.
10208 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10209 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10211 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10212 * xrdb.c (magic_file_p, search_magic_path):
10213 Omit last arg SUFFIX; it was always 0. All callers changed.
10214 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10216 * xfont.c (xfont_match): Avoid need for strlen.
10218 * xfns.c: Don't assume strlen fits in int.
10219 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10221 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10222 not unsigned long, as we prefer signed integers. All callers changed.
10223 Detect integer overflow in repeat count.
10224 (message_dolog): Don't assume print length fits in 39 bytes.
10225 (display_mode_element): Don't assume strlen fits in int.
10227 * termcap.c: Don't assume sizes fit in int and never overflow.
10228 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10229 (gobble_line): Check for size-calculation overflow.
10231 * minibuf.c (Fread_buffer):
10232 * lread.c (intern, intern_c_string):
10233 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10234 Don't assume string length fits in int.
10236 * keyboard.c (parse_tool_bar_item):
10237 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10239 * font.c: Don't assume string length fits in int.
10240 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10241 Use ptrdiff_t, not int.
10242 (font_intern_prop): Don't assume string length fits in int.
10243 Don't assume integer property fits in fixnum.
10244 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10246 * filelock.c: Fix some buffer overrun and integer overflow issues.
10247 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10248 Reformulate so as not to need the command string.
10249 Invoke gzip -cd rather than gunzip, as it's more portable.
10250 (lock_info_type, lock_file_1, lock_file):
10251 Don't assume pid_t and time_t fit in unsigned long.
10252 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10253 (current_lock_owner): Prefer signed type for sizes.
10254 Use memcpy, not strncpy, where memcpy is what is really wanted.
10255 Don't assume (via atoi) that time_t and pid_t fit in int.
10256 Check for time_t and/or pid_t out of range, e.g., via a network share.
10257 Don't alloca where an auto var works fine.
10259 * fileio.c: Fix some integer overflow issues.
10260 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10261 Don't assume string length fits in int.
10262 (directory_file_name): Don't assume string length fits in long.
10263 (make_temp_name): Don't assume pid fits in int, or that its print
10264 length is less than 20.
10266 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10268 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10270 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10272 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10273 We prefer signed integers, even for size calculations.
10275 * emacs.c: Don't assume string length fits in 'int'.
10276 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10277 (main): Don't invoke strlen when not needed.
10279 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10280 (XD_DEBUG_MESSAGE): Don't waste a byte.
10282 * callproc.c (getenv_internal_1, getenv_internal)
10283 (Fgetenv_internal):
10284 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10286 * lread.c (invalid_syntax): Omit length argument.
10287 All uses changed. This doesn't fix a bug, but it simplifies the
10288 code away from its former Hollerith-constant appearance, and it's
10289 one less 'int' to worry about when looking at integer-overflow issues.
10290 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10292 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10293 This didn't break anything, but it didn't help either.
10294 It's confusing to put a bogus integer in a place where the actual
10295 value does not matter.
10296 (LIST_END_P): Remove unused macro and its bogus comment.
10297 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10299 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10300 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10302 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10303 We prefer signed types, and the value cannot exceed the EMACS_INT
10304 range anyway (because otherwise the length would not be representable).
10305 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10306 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10307 This avoids a GCC warning when WIDE_EMACS_INT.
10309 * indent.c (sane_tab_width): New function.
10310 (current_column, scan_for_column, Findent_to, position_indentation)
10311 (compute_motion): Use it. This is just for clarity.
10312 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10314 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10316 * lisp.h (lint_assume): New macro.
10317 * composite.c (composition_gstring_put_cache):
10318 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10320 * editfns.c, insdel.c:
10321 Omit unnecessary forward decls, to simplify future changes.
10323 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10325 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10327 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10328 Use much-faster test for byte-length change.
10329 Don't assume string byte-length fits in 'int'.
10330 Check that character arg fits in 'int'.
10331 (mapcar1): Declare byte as byte, for clarity.
10333 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10335 * fns.c (concat): Catch string overflow earlier.
10336 Do not rely on integer wraparound.
10338 * dispextern.h (struct it.overlay_strings_charpos)
10339 (struct it.selective): Now EMACS_INT, not int.
10340 * xdisp.c (forward_to_next_line_start)
10341 (back_to_previous_visible_line_start)
10342 (reseat_at_next_visible_line_start, next_element_from_buffer):
10343 Don't arbitrarily truncate the value of 'selective' to int.
10345 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10347 * composite.c: Don't truncate sizes to 'int'.
10348 (composition_gstring_p, composition_reseat_it)
10349 (composition_adjust_point): Use EMACS_INT, not int.
10350 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10351 not EMACS_UINT, for indexes.
10353 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10355 * buffer.c: Include <verify.h>.
10356 (struct sortvec.priority, struct sortstr.priority):
10357 Now EMACS_INT, not int.
10358 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10359 (struct sortstr.size, record_overlay_string)
10360 (struct sortstrlist.size, struct sortlist.used):
10361 Don't truncate size to int.
10362 (record_overlay_string): Check for size-calculation overflow.
10363 (init_buffer_once): Check at compile-time, not run-time.
10365 2011-06-22 Jim Meyering <meyering@redhat.com>
10367 Don't leak an XBM-image-sized buffer
10368 * image.c (xbm_load): Free the image buffer after using it.
10370 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10373 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10374 that Sun C diagnosed.
10375 * fns.c (secure_hash): Fix pointer signedness issue.
10376 * intervals.c (static_offset_intervals): New function.
10377 (offset_intervals): Use it.
10379 2011-06-21 Leo Liu <sdl.web@gmail.com>
10382 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10385 * fns.c (secure_hash): Rename from crypto_hash_function and change
10386 the first arg to accept symbols.
10387 (Fsecure_hash): New primitive.
10388 (syms_of_fns): New symbols.
10390 2011-06-20 Deniz Dogan <deniz@dogan.se>
10392 * process.c (Fset_process_buffer): Clarify return value in
10395 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10397 * dispnew.c (add_window_display_history): Use BVAR.
10399 * xdisp.c (debug_method_add): Use BVAR.
10400 (check_window_end, dump_glyph_matrix, dump_glyph)
10401 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10403 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10406 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10407 check till after the cache is created in init_frame_faces.
10409 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10411 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10413 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10415 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10416 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10417 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10419 Improve buffer-overflow checking (Bug#8873).
10420 * fileio.c (Finsert_file_contents):
10421 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10422 Remove the old (too-loose) buffer overflow checks.
10423 They weren't needed, since make_gap checks for buffer overflow.
10424 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10425 The old code merely checked for Emacs fixnum overflow, and relied
10426 on undefined (wraparound) behavior. The new code avoids undefined
10427 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10429 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10430 Tune. Don't use wider integers than needed. Don't use alloca.
10431 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10433 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10435 * insdel.c, lisp.h (buffer_overflow): New function.
10436 (insert_from_buffer_1, replace_range, replace_range_2):
10437 * insdel.c (make_gap_larger):
10438 * editfns.c (Finsert_char):
10439 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10441 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10443 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10445 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10447 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10448 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10450 * fileio.c: Don't assume EMACS_INT fits in off_t.
10451 (emacs_lseek): New static function.
10452 (Finsert_file_contents, Fwrite_region): Use it.
10453 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10455 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10457 * fns.c: Don't overflow int when computing a list length.
10458 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10459 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10460 truncation on 64-bit hosts. Check for QUIT every
10461 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10462 faster and is responsive enough.
10463 (Flength): Report an error instead of overflowing an integer.
10464 (Fsafe_length): Return a float if the value is not representable
10465 as a fixnum. This shouldn't happen except in contrived situations.
10466 (Fnthcdr, Fsort): Don't assume list length fits in int.
10467 (Fcopy_sequence): Don't assume vector length fits in int.
10469 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10470 (header_size, word_size): New constants.
10471 (allocate_vectorlike): Don't check size overflow here.
10472 (allocate_vector): Check it here instead, since this is the only
10473 caller of allocate_vectorlike that could cause overflow.
10474 Check that the new vector's length is representable as a fixnum.
10476 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10477 The previous code was bogus. For example, next_almost_prime (32)
10478 returned 39, which is undesirable as it is a multiple of 3; and
10479 next_almost_prime (24) returned 25, which is a multiple of 5 so
10480 why was the code bothering to check for multiples of 7?
10482 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10484 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10486 Variadic C functions now count arguments with ptrdiff_t.
10487 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10488 Back then I didn't know that the Emacs coding style prefers signed int.
10489 Also, in the meantime I found a few more instances where arguments
10490 were being counted with int, which may truncate counts on 64-bit
10491 machines, or EMACS_INT, which may be unnecessarily wide.
10492 * lisp.h (struct Lisp_Subr.function.aMANY)
10493 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10494 Arg counts are now ptrdiff_t, not size_t.
10495 All variadic functions and their callers changed accordingly.
10496 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10497 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10498 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10499 * callint.c (Fcall_interactively): Check arg count for overflow,
10500 to avoid potential buffer overrun. Use signed char, not 'int',
10501 for 'varies' array, so that we needn't bother to check its size
10502 calculation for overflow.
10503 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10504 * eval.c (apply_lambda):
10505 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10506 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10507 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10509 * callint.c (Fcall_interactively): Don't use index var as event count.
10511 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10512 * mem-limits.h (SIZE): Remove; no longer used.
10514 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10516 Remove unnecessary casts.
10517 * xterm.c (x_term_init):
10518 * xfns.c (x_set_border_pixel):
10519 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10520 These aren't needed now that we assume ANSI C.
10522 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10523 It's more likely to cause problems (due to unsigned overflow)
10526 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10528 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10530 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10532 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10534 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10536 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10538 GLYPH_CODE_FACE returns EMACS_INT, not int.
10539 * dispextern.h (merge_faces):
10540 * xfaces.c (merge_faces):
10541 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10542 Don't assume EMACS_INT fits in int.
10544 * character.h (CHAR_VALID_P): Remove unused parameter.
10545 * fontset.c, lisp.h, xdisp.c: All uses changed.
10547 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10549 * fns.c (concat): Minor tuning based on overflow analysis.
10550 This doesn't fix any bugs. Use int to hold character, instead
10551 of constantly refetching from Emacs object. Use XFASTINT, not
10552 XINT, for value known to be a character. Don't bother comparing
10553 a single byte to 0400, as it's always less.
10555 * floatfns.c (Fexpt):
10556 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10558 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10561 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10563 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10564 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10565 incorrectly succeed when S was a string, because 4294967386 was
10566 truncated before it was used.
10568 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10569 Otherwise, an out-of-range integer could cause undefined behavior
10572 * composite.c: Use int, not EMACS_INT, for characters.
10573 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10574 EMACS_INT, for values that are known to be in character range.
10575 This doesn't fix any bugs but is the usual style inside Emacs and
10576 may generate better code on 32-bit machines.
10578 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10579 This is for reasons similar to the recent CHAR_STRING fix.
10580 * charset.c (Fencode_char): Check that character arg is actually
10581 a character. Pass an int to ENCODE_CHAR.
10582 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10583 wider than 'int', as a compile-time check to prevent future regressions
10586 * character.c (char_string): Remove unnecessary casts.
10588 Make sure a 64-bit char is never passed to CHAR_STRING.
10589 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10590 by silently ignoring the top 32 bits, allowing some values
10591 that were far too large to be valid characters.
10592 * character.h: Include <verify.h>.
10593 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10594 arguments are no wider than unsigned, as a compile-time check
10595 to prevent future regressions in this area.
10597 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10598 (Fsubst_char_in_region):
10600 * xdisp.c (decode_mode_spec_coding):
10601 Adjust to CHAR_STRING's new requirement.
10602 * editfns.c (Finsert_char, Fsubst_char_in_region):
10603 * fns.c (concat): Check that character args are actually
10604 characters. Without this test, these functions did the wrong
10605 thing with wildly out-of-range values on 64-bit hosts.
10607 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10608 These casts should not be needed on 32-bit hosts, either.
10609 * keyboard.c (read_char):
10610 * lread.c (Fload): Remove casts to unsigned.
10612 * lisp.h (UNSIGNED_CMP): New macro.
10613 This fixes comparison bugs on 64-bit hosts.
10614 (ASCII_CHAR_P): Use it.
10615 * casefiddle.c (casify_object):
10616 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10617 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10618 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10619 * dispextern.h (FACE_FROM_ID):
10620 * keyboard.c (read_char): Use UNSIGNED_CMP.
10622 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10623 not to EMACS_INT, to avoid GCC warning.
10625 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10627 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10628 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10629 isn't needed on 32-bit machines.
10631 * buffer.c (Fgenerate_new_buffer_name):
10632 Use EMACS_INT for count, not int.
10633 (advance_to_char_boundary): Return EMACS_INT, not int.
10635 * data.c (Qcompiled_function): Now static.
10637 * window.c (window_body_lines): Now static.
10639 * image.c (gif_load): Rename local to avoid shadowing.
10641 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10642 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10643 * alloc.c (make_save_value): Integer argument is now of type
10644 ptrdiff_t, not int.
10645 (mark_object): Use ptrdiff_t, not int.
10646 * lisp.h (pD): New macro.
10647 * print.c (print_object): Use it.
10649 * alloc.c: Use EMACS_INT, not int, to count objects.
10650 (total_conses, total_markers, total_symbols, total_vector_size)
10651 (total_free_conses, total_free_markers, total_free_symbols)
10652 (total_free_floats, total_floats, total_free_intervals)
10653 (total_intervals, total_strings, total_free_strings):
10654 Now EMACS_INT, not int. All uses changed.
10655 (Fgarbage_collect): Compute overall total using a double, so that
10656 integer overflow is less likely to be a problem. Check for overflow
10657 when converting back to an integer.
10658 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10659 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10660 These were 'int' variables that could overflow on 64-bit hosts;
10661 they were never used, so remove them instead of repairing them.
10662 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10663 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10664 Previously, this ceilinged at INT_MAX, but that doesn't work on
10666 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10668 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10669 (allocate_vectorlike): Check for ptrdiff_t overflow.
10670 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10671 when a (possibly-narrower) signed value would do just as well.
10672 We prefer using signed arithmetic, to avoid comparison confusion.
10674 * alloc.c: Catch some string size overflows that we were missing.
10675 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10676 for convenience in STRING_BYTES_MAX.
10677 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10678 The definition here is exact; the one in lisp.h was approximate.
10679 (allocate_string_data): Check for string overflow. This catches
10680 some instances we weren't catching before. Also, it catches
10681 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10682 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10683 and ptrdiff_t and EMACS_INT are both 64 bits.
10685 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10686 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10687 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10689 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10691 * alloc.c (Fmake_string): Check for out-of-range init.
10693 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10695 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10697 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10699 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10700 xg_get_default_scrollbar_width.
10702 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10703 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10704 (style_changed_cb): Call update_theme_scrollbar_width and call
10705 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10706 all frames (Bug#8505).
10707 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10708 Call gtk_window_set_resizable if HAVE_GTK3.
10709 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10710 and height if HAVE_GTK3 (Bug#8505).
10711 (scroll_bar_width_for_theme): New variable.
10712 (update_theme_scrollbar_width): New function.
10713 (xg_get_default_scrollbar_width): Move code to
10714 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10715 (xg_initialize): Call update_theme_scrollbar_width.
10717 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10719 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10721 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10723 * frame.c (make_frame): Call other_buffer_safely instead of
10726 * window.c (temp_output_buffer_show): Call display_buffer with
10727 second argument Vtemp_buffer_show_specifiers and reset latter
10728 immediately after the call.
10729 (Vtemp_buffer_show_specifiers): New variable.
10730 (auto_window_vscroll_p, next_screen_context_lines)
10731 (Vscroll_preserve_screen_position): Remove leading asterisks from
10734 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10736 Fix minor problems found by GCC 4.6.0 static checking.
10737 * buffer.c (Qclone_number): Remove for now, as it's unused.
10738 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10739 (record_buffer): Remove unused local.
10740 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10741 (set_frame_buffer_list): Remove; unused.
10742 * frame.h (other_visible_frames): Remove decl.
10743 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.

10745 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10747 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10748 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10749 Define only if HAVE_GPM.
10750 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10751 (update_hints_inhibit): Remove; never set. All uses removed.
10752 * widgetprv.h (emacsFrameClassRec): Remove decl.
10753 * window.c (delete_deletable_window): Now returns void, since it
10754 wasn't returning anything.
10755 (compare_window_configurations): Remove unused locals.
10756 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10757 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10758 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10759 the same widths as pointers. This follows up on the 2011-05-06 patch.
10760 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10761 * xterm.h: Likewise.

10769 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10771 * image.c (gif_load): Add animation frame delay to the metadata.
10772 (syms_of_image): Use DEFSYM. New symbol `delay'.
10774 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10776 * window.c (delete_deletable_window): Re-add.
10777 (Fset_window_configuration): Rewrite to handle dead buffers and
10778 consequently deletable windows.
10779 (window_tree, Fwindow_tree): Remove. Supply functionality in
10781 (compare_window_configurations): Simplify code.
10783 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10785 * image.c (imagemagick_load_image): Fix type mismatch.
10786 (Fimagemagick_types): Likewise.
10788 * window.h (replace_buffer_in_windows): Declare.
10790 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10792 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10793 Qclone_number. Remove external declaration of Qdelete_window.
10794 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10796 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10797 Run Qbuffer_list_update_hook if allowed.
10798 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10799 buffer list implementation.
10800 (other_buffer_safely): New function.
10801 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10802 calls to replace_buffer_in_windows and
10803 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10805 (record_buffer): Inhibit quitting and rewrite using quittable
10806 functions. Run Qbuffer_list_update_hook if allowed.
10807 (Frecord_buffer, Funrecord_buffer): New functions.
10808 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10809 Move switch-to-buffer to window.el.
10810 (bury-buffer): Move to window.el.
10811 (Vbuffer_list_update_hook): New variable.
10813 * lisp.h (other_buffer_safely): Add prototype in buffer.c

10818 (replace_buffer_in_all_windows): Remove prototype.
10819 (replace_buffer_in_windows_safely): Add prototype.
10821 * window.c: Declare Qdelete_window static again. Move down
10822 declaration of select_count.
10823 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10824 (Fother_window): Move to window.el.
10825 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10826 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.

10829 (replace_buffer_in_windows): Implement by calling
10830 Qreplace_buffer_in_windows.
10831 (replace_buffer_in_all_windows): Remove with some functionality
10832 moved into replace_buffer_in_windows_safely.
10833 (replace_buffer_in_windows_safely): New function.
10834 (select_window_norecord, select_frame_norecord): Move in front
10835 of run_window_configuration_change_hook. Remove now obsolete
10837 (Fset_window_buffer): Rewrite doc-string.
10838 Call Qrecord_window_buffer.
10839 (keys_of_window): Move binding for other-window to window.el.
10841 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10843 * dispextern.h (struct image): Replace data member, whose int_val
10844 and ptr_val fields were not used by anything, with a single
10847 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
10848 (gif_clear_image, gif_load, imagemagick_load_image)

11282 (display_prop_intangible_p): Reimplement to call
11283 handle_display_spec instead of single_display_spec_intangible_p.

11295 value of a `display' property is a "replacing spec".
11296 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11297 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11327 * gnutls.c: Use Emacs's memory allocators.
11328 Without this change, the gnutls library would invoke malloc etc.
11329 directly, which causes problems on non-SYNC_INPUT hosts, and which
11330 runs afoul of improving memory_full behavior. (Bug#8761)
11331 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11332 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11333 xfree instead of the default malloc, realloc, free.
11334 (Fgnutls_boot): No need to check for memory allocation failure,
11335 since xmalloc does that for us.

11355 * lisp.h (struct Lisp_Hash_Table):
11356 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11357 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11358 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11359 * alloc.c (allocate_vectorlike):
11360 Check for overflow in vector size calculations.
11361 * ccl.c (ccl_driver):
11362 Check for overflow when converting EMACS_INT to int.
11363 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11364 need to be updated by these changes.
11365 * fns.c (make_hash_table, maybe_resize_hash_table):
11366 Check for integer overflow with large hash tables.
11367 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11368 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11369 (SXHASH_REDUCE): New macro.
11370 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11371 Use it instead of discarding useful hash info with large hash values.
11372 (sxhash_float): New function.
11373 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11374 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11375 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11376 Rewrite to use FIXNUM_BITS, as this simplifies things.
11377 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11378 Adjust signatures to match updated version of code.
11379 (consing_since_gc): Now EMACS_INT, since a single hash table can
11380 use more than INT_MAX bytes.
11382 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11384 Make it possible to build with GCC-4.6+ -O2 -flto.

11393 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11395 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11396 Update dependencies.
11398 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11400 * data.c (init_data): Remove code for UTS, this system is not
11403 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11405 Don't force ./temacs to start in terminal mode.
11407 * frame.c (make_initial_frame): Initialize faces in all cases, not
11408 only when CANNOT_DUMP is defined.
11409 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11411 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11413 * dispnew.c (add_window_display_history): Use const for the string
11414 pointer. Remove declaration, not needed.
11416 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11418 Use 'inline', not 'INLINE'.
11419 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11420 * alloc.c, fontset.c (INLINE): Remove.
11421 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11422 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11423 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11424 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11425 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11427 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11429 Make it possible to run ./temacs.
11431 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11432 syms_of_callproc does the same thing. Remove test for
11433 "initialized", do it in the caller.
11434 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11436 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11438 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11439 (read_minibuf): Use get_minibuffer.
11440 (syms_of_minibuf): Use DEFSYM.
11441 (Qmetadata): New var.
11442 * data.c (Qbuffer): Don't make it static.
11443 (syms_of_data): Use DEFSYM.
11445 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11447 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11448 (CCL_CODE_MIN): New macro.
11450 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11452 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11454 * eval.c (Qdebug): Now static.
11455 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11456 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11457 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11459 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11461 * image.c: Various fixes to ImageMagick code comments.
11462 (Fimagemagick_types): Doc fix.
11464 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11466 Minor fixes prompted by GCC 4.6.0 warnings.
11468 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11470 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11471 (x_clipboard_manager_save_all): Move extern decl to ...
11472 * xterm.h: ... here, so that it can be checked for consistency.
11474 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11476 * xselect.c (x_clipboard_manager_save_frame)
11477 (x_clipboard_manager_save_all): New functions.
11478 (Fx_clipboard_manager_save): Lisp function deleted.
11480 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11481 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11483 * xterm.h: Update prototype.
11485 2011-05-28 William Xu <william.xwl@gmail.com>
11487 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11488 exiting (Bug#8239).
11490 2011-05-28 Jim Meyering <meyering@redhat.com>
11492 Avoid a sign-extension bug in crypto_hash_function.
11493 * fns.c (to_uchar): Define.
11494 (crypto_hash_function): Use it to convert some newly-signed
11495 variables to unsigned, to avoid sign-extension bugs. For example,
11496 without this change, (md5 "truc") would evaluate to
11497 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11498 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11499 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11501 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11503 Integer overflow fixes.
11505 * dbusbind.c: Serial number integer overflow fixes.
11506 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11507 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11508 to hold a serial number that is too large for a fixnum.
11509 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11510 Check for serial numbers out of range. Decode any serial number
11511 that was so large that it became a float. (Bug#8722)
11513 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11514 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11515 Use XFASTINT rather than XUINT when numbers are nonnegative.
11516 (xd_append_arg, Fdbus_method_return_internal):
11517 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11518 arguments, check that Lisp number is nonnegative, rather than
11519 silently wrapping negative numbers around. (Bug#8722)
11520 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11523 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11525 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11527 ccl: Add integer overflow checks.
11528 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11529 (IN_INT_RANGE): New macros.
11530 (ccl_driver): Use them to check for integer overflow when
11531 decoding a CCL program. Many of the new checks are whether XINT (x)
11532 fits in int; it doesn't always, on 64-bit hosts. The new version
11533 doesn't catch all possible integer overflows, but it's an
11534 improvement. (Bug#8719)
11536 * alloc.c (make_event_array): Use XINT, not XUINT.
11537 There's no need for unsigned here.
11539 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11540 This follows up to the 2011-05-06 change that substituted uintptr_t
11541 for EMACS_INT. This case wasn't caught back then.
11543 Rework Fformat to avoid integer overflow issues.
11544 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11545 now (part of C89). Include <verify.h>.
11546 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11547 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11548 (Fformat): Avoid the prepass trying to compute sizes; it was only
11549 approximate and thus did not catch overflow reliably. Instead, walk
11550 through the format just once, formatting and computing sizes as we go,
11551 checking for integer overflow at every step, and allocating a larger
11552 buffer as needed. Keep track separately whether the format is
11553 multibyte. Keep only the most-recently calculated precision, rather
11554 than them all. Record whether each argument has been converted to
11555 string. Use EMACS_INT, not int, for byte and char and arg counts.
11556 Support field widths and precisions larger than INT_MAX. Avoid
11557 sprintf's undefined behavior with conversion specifications such as %#d
11558 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11559 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11560 formatting out-of-range floating point numbers with int
11561 formats. (Bug#8668)
11563 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11565 * data.c: Avoid integer truncation in expressions involving floats.
11566 * data.c: Include <intprops.h>.
11567 (arith_driver): When there's an integer overflow in an expression
11568 involving floating point, convert the integers to floating point
11569 so that the resulting value does not suffer from catastrophic
11570 integer truncation. For example, on a 64-bit host (* 4
11571 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11572 Do not rely on undefined behavior after integer overflow.
11574 merge count_size_as_multibyte, parse_str_to_multibyte
11575 * character.c, character.h (count_size_as_multibyte):
11576 Rename from parse_str_to_multibyte; all uses changed.
11577 Check for integer overflow.
11578 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11579 since it's now a duplicate of the other. This is more of
11580 a character than a buffer op, so better that it's in character.c.
11581 * fns.c, print.c: Adjust to above changes.
11583 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11585 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11587 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11589 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11590 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11591 (x_clipboard_manager_save): Now static.
11592 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11594 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11595 (crypto_hash_function): Now static.
11596 Fix pointer signedness problems. Avoid unnecessary initializations.
11598 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11600 * termhooks.h (Vselection_alist): Make it terminal-local.
11602 * terminal.c (create_terminal): Initialize it.
11604 * xselect.c: Support for clipboard managers.
11605 (Vselection_alist): Move to termhooks.h as terminal-local var.
11606 (LOCAL_SELECTION): New macro.
11607 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11608 (symbol_to_x_atom): Remove gratuitous arg.
11609 (x_handle_selection_request, lisp_data_to_selection_data)
11610 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11611 (x_own_selection, x_get_local_selection, x_convert_selection):
11612 New arg, specifying work frame. Use terminal-local Vselection_alist.
11613 (some_frame_on_display): Delete unused function.
11614 (Fx_own_selection_internal, Fx_get_selection_internal)
11615 (Fx_disown_selection_internal, Fx_selection_owner_p)
11616 (Fx_selection_exists_p): New optional frame arg.
11617 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11618 (x_handle_selection_clear): Don't treat other terminals with the
11619 same keyboard specially. Use the terminal-local Vselection_alist.
11620 (x_clear_frame_selections): Use Frun_hook_with_args.
11622 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11624 * xterm.h: Add support for those atoms.
11626 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11628 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11629 (converted_selections, conversion_fail_tag): New global variables.
11630 (x_selection_request_lisp_error): Free the above.
11631 (x_get_local_selection): Remove unnecessary code.
11632 (x_reply_selection_request): Args changed; handle arbitrary array
11633 of converted selections stored in converted_selections.
11634 Separate the XChangeProperty and SelectionNotify steps.
11635 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11636 (x_convert_selection): New function.
11637 (x_handle_selection_event): Simplify.
11638 (x_get_foreign_selection): Don't ignore incoming requests while
11639 waiting for an answer; this will fail when we implement
11640 SAVE_TARGETS, and seems unnecessary anyway.
11641 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11642 (Vx_sent_selection_functions): Doc fix.
11644 2011-05-26 Leo Liu <sdl.web@gmail.com>
11646 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11648 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11650 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11652 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11653 for fringe update if it has periodic bitmap.
11654 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11655 and fringe_bitmap_periodic_p.
11657 * fringe.c (get_fringe_bitmap_data): New function.
11658 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11659 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11660 row. Mark glyph row for fringe update if periodicity changed.
11662 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11663 for fringe update unless it has periodic bitmap.
11665 2011-05-25 Kenichi Handa <handa@m17n.org>
11667 * xdisp.c (get_next_display_element): Set correct it->face_id for
11668 a static composition.

11679 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11681 * gnutls.c: Remove unused macros.
11682 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11683 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11684 Remove macros that are defined and never used.
11685 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11687 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11689 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11690 (Fx_get_selection_internal): Minor cleanup.
11691 (Fx_own_selection_internal): Rename arguments for consistency with
11694 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11696 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

11709 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11710 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11711 and add some more files.

11716 report_file_error introduced by the change from 2011-05-07.
11718 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11720 * systime.h (Time): Define only if emacs is defined.
11721 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11722 where the include path doesn't have X11/X.h by default. See
11723 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11725 2011-05-20 Kenichi Handa <handa@m17n.org>
11727 * composite.c (find_automatic_composition): Fix previous change.
11729 2011-05-20 Glenn Morris <rgm@gnu.org>
11731 * lisp.mk: New file, split from Makefile.in.
11732 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11733 (shortlisp): Remove.
11734 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11736 2011-05-19 Glenn Morris <rgm@gnu.org>
11738 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11739 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11740 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11741 (lisp): Set the order to that of loadup.el.
11742 (shortlisp): Make it a copy of $lisp.
11743 (SOME_MACHINE_LISP): Remove.
11744 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11745 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11747 2011-05-18 Kenichi Handa <handa@m17n.org>
11749 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11750 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11751 (find_automatic_composition): Mostly rewrite for efficiency.
11753 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11755 * makefile.w32-in: Update dependencies.
11757 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11759 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11760 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11762 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11764 Fix some integer overflow issues, such as string length overflow.
11766 * insdel.c (count_size_as_multibyte): Check for string overflow.
11768 * character.c (lisp_string_width): Check for string overflow.
11769 Use EMACS_INT, not int, for string indexes and lengths; in
11770 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11771 the resulting string length overflows an EMACS_INT; instead,
11772 report a string overflow if no precision given. When checking for
11773 precision exhaustion, use a check that cannot possibly have
11774 integer overflow. (Bug#8675)
11775 * character.h (lisp_string_width): Adjust to new signature.
11777 * alloc.c (string_overflow): New function.
11778 (Fmake_string): Use it. This doesn't change behavior, but saves
11779 a few bytes and will simplify future changes.
11780 * character.c (string_escape_byte8): Likewise.
11781 * lisp.h (string_overflow): New decl.
11783 Fixups, following up to the user-interface timestamp change.
11784 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11785 for UI timestamps, instead of unsigned long.
11786 * msdos.c (mouse_get_pos): Likewise.
11787 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11788 * w32gui.h (Time): Define by including "systime.h" rather than by
11789 declaring it ourselves. (Bug#8664)
11791 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11792 * image.c (clear_image_cache): Likewise.
11794 * term.c (term_mouse_position): Don't assume time_t wraparound.
11796 Be more systematic about user-interface timestamps.
11797 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11798 and sometimes 'EMACS_UINT', to represent these timestamps.
11799 This change causes it to use 'Time' uniformly, as that's what X uses.
11800 This makes the code easier to follow, and makes it easier to catch
11801 integer overflow bugs such as Bug#8664.
11802 * frame.c (Fmouse_position, Fmouse_pixel_position):
11803 Use Time, not unsigned long, for user-interface timestamps.
11804 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11805 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11806 * keyboard.h (last_event_timestamp): Likewise.
11807 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11808 * menu.h (xmenu_show): Likewise.
11809 * term.c (term_mouse_position): Likewise.
11810 * termhooks.h (struct input_event.timestamp): Likewise.
11811 (struct terminal.mouse_position_hook): Likewise.
11812 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11813 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11814 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11815 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11816 what it was before.
11817 * menu.h, termhooks.h: Include "systime.h", for Time.
11819 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11820 Don't assume that the difference between two unsigned long values
11821 can fit into an integer. At this point, we know button_down_time
11822 <= event->timestamp, so the difference must be nonnegative, so
11823 there's no need to cast the result if double-click-time is
11824 nonnegative, as it should be; check that it's nonnegative, just in
11825 case. This bug is triggered when events are more than 2**31 ms
11826 apart (about 25 days). (Bug#8664)
11828 * xselect.c (last_event_timestamp): Remove duplicate decl.
11829 (x_own_selection): Remove needless cast to unsigned long.
11831 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11832 that always fit in int. Use a sentinel instead of a counter, to
11833 avoid a temp and to allay GCC's concerns about possible int overflow.
11834 * frame.h (struct frame): Use int for menu_bar_items_used
11835 instead of EMACS_INT, since it always fits in int.
11837 * menu.c (grow_menu_items): Check for int overflow.
11839 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11841 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11842 Before, the code was not consistent. These values cannot exceed
11843 2**31 - 1 so there's no need to make them unsigned.
11844 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11845 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11846 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11848 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11850 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11851 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11852 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11853 presumably because the widths might not match.
11855 * window.c (size_window): Avoid needless test at loop start.
11857 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11859 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11861 2011-05-12 Drew Adams <drew.adams@oracle.com>
11863 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11865 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11867 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11868 `width' to `bar_area_x' and `bar_area_width', respectively.
11869 (x_scroll_run): Take account of fringe background extension.
11871 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11872 Rename local vars `left' and `width' to `bar_area_x' and
11873 `bar_area_width', respectively.
11874 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11875 background extension.
11877 2011-05-10 Jim Meyering <meyering@redhat.com>
11879 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11881 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11883 * image.c (Finit_image_library): Return t for built-in image types,
11884 like pbm and xbm. (Bug#8640)
11886 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11888 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11890 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11892 * w32console.c (Fset_screen_color): Doc fix.
11893 (Fget_screen_color): New function.
11894 (syms_of_ntterm): Defsubr it.
11896 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11897 unlink the temporary file if Fcall_process didn't create it in the
11899 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11900 child process will be redirected to a file specified with `:file'.
11901 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11902 cue to call_process_cleanup not to close that handle.
11904 2011-05-07 Ben Key <bkey76@gmail.com>
11906 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11907 one of two shell specific rules, either bootstrap-temacs-CMD or
11908 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11909 to the previous implementation of the bootstrap-temacs rule.
11910 The bootstrap-temacs-CMD rule is similar to the previous
11911 implementation of the bootstrap-temacs rule except that it
11912 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11915 These changes, along with some changes to nt/configure.bat,
11916 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11917 earlier fix to add support for --cflags and --ldflags options
11918 that include quotes so that it works whether make uses cmd or
11921 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11923 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11924 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11926 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11927 a string. Handle both cases.
11928 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11929 (Fdbus_register_method): Use Qinvalid_function.
11931 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11933 * makefile.w32-in: Update dependencies.
11934 (LISP_H): Add inttypes.h and stdin.h.
11935 (PROCESS_H): Add unistd.h.
11937 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11939 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11940 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11942 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11944 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11946 * term.c (vfatal): Remove stray call to va_end.
11947 It's not needed and the C Standard doesn't allow it here anyway.
11949 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11950 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11952 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11955 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11957 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11959 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11961 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11963 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11965 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11966 * charset.c (Fdefine_charset_internal): Don't initialize
11967 charset.code_space[15]. The value was garbage, on hosts with
11968 32-bit int (Bug#8600).
11970 * lread.c (read_integer): Be more consistent with string-to-number.
11971 Use string_to_number to do the actual conversion; this avoids
11972 rounding errors and fixes some other screwups. Without this fix,
11973 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11974 (digit_to_number): Move earlier, for benefit of read_integer.
11975 Return -1 if the digit is out of range for the base, -2 if it is
11976 not a digit in any supported base. (Bug#8602)
11978 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11980 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11981 to match comment at start of function. This also removes a
11982 GCC warning about overflow in a 32+64-bit port.
11984 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11986 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11987 Reported by Stefan Monnier in
11988 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11989 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11990 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11992 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11993 (EMACS_UINTPTR): Likewise, with uintptr_t.
11995 * lisp.h: Prefer 64-bit EMACS_INT if available.
11996 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11997 on 32-bit hosts that have 64-bit int, so that they can access
11999 However, temporarily disable this change unless the temporary
12000 symbol WIDE_EMACS_INT is defined.
12002 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12004 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12005 This removes an assumption that EMACS_INT and long are the same
12006 width as pointers. The assumption is true for Emacs porting targets
12007 now, but we want to make other targets possible.
12008 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12009 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12010 In the rest of the code, change types of integers that hold casted
12011 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12012 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12013 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12014 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12015 No need to cast type when ORing.
12016 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12017 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12018 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12019 assume EMACS_INT is the same width as char *.
12020 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12021 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12022 Remove no-longer-needed casts.
12023 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12024 (xg_tool_bar_help_callback, xg_make_tool_item):
12025 Use EMACS_INTPTR to hold an integer
12026 that will be cast to void *; this can avoid a GCC warning
12027 if EMACS_INT is not the same width as void *.
12028 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12029 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12030 (current_message_1, set_message_1):
12031 Use a local to convert to proper width without a cast.
12032 * xmenu.c (dialog_selection_callback): Likewise.
12034 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12035 Also, don't assume VALBITS / RAND_BITS is less than 5,
12036 and don't rely on undefined behavior when shifting a 1 left into
12038 * lisp.h (get_random): Change signature to match.
12040 * lread.c (hash_string): Use size_t, not int, for hash computation.
12041 Normally we prefer signed values; but hashing is special, because
12042 it's better to use unsigned division on hash table sizes so that
12043 the remainder is nonnegative. Also, size_t is the natural width
12044 for hashing into memory. The previous code used 'int', which doesn't
12045 retain enough info to hash well into very large tables.
12046 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12048 * dbusbind.c: Don't possibly lose pointer info when converting.
12049 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12050 Use XPNTR rather than XHASH, so that the high-order bits of
12051 the pointer aren't lost when converting through void *.
12053 * eval.c (Fautoload): Don't double-shift a pointer.
12055 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12057 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12059 * gnutls.c (DEF_GNUTLS_FN):
12060 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12062 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12064 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12067 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12069 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12070 New version that can reserve upto 2GB of heap space.
12072 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12074 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12076 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12078 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12079 `gnutls_certificate_set_x509_key_file'.
12081 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12083 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12084 Update dependencies.
12086 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12088 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12089 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12090 Remove unused parameter `fildes'.
12091 * process.c (read_process_output, send_process): Don't pass it.
12093 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12095 Fix previous change: the library cache is defined in w32.c.
12096 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12097 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12099 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12101 Implement dynamic loading of GnuTLS on Windows.
12103 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12104 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12105 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12108 * gnutls.c (Qgnutls_dll): Define.
12109 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12110 (gnutls_*): Declare function pointers.
12111 (init_gnutls_functions): New function to initialize function pointers.
12112 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12113 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12114 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12115 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12116 (emacs_gnutls_write, emacs_gnutls_read)
12117 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12118 (Fgnutls_available_p): New function.
12119 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12120 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12121 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12123 * image.c: Include w32.h.
12124 (Vimage_type_cache): Delete.
12125 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12126 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12127 (w32_delayed_load): Move to w32.c.
12129 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12131 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12132 (w32_delayed_load): Move from image.c. When loading a library, record
12133 its filename in the :loaded-from property of the library id.
12134 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12135 Initialize and staticpro them.
12136 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12138 * process.c: Include lisp.h before w32.h, not after.
12139 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12140 instead of gnutls_record_check_pending.
12142 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12144 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12146 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12147 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12150 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12152 * xterm.c (x_set_frame_alpha): Do not set property on anything
12153 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12155 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12157 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12159 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12161 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12162 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12168 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12169 (Qgnutls_bootprop_callbacks_verify): Make static.
12171 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12173 * callproc.c: Indentation fixup.
12175 * sysdep.c (wait_for_termination_1): Make static.
12176 (wait_for_termination, interruptible_wait_for_termination):
12177 Move after wait_for_termination_1.
12179 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12181 * sysdep.c (interruptible_wait_for_termination): New function
12182 which is like wait_for_termination, but allows keyboard
12185 * callproc.c (Fcall_process): Add (:file "file") as an option for
12187 (Fcall_process_region): Ditto.
12189 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12191 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12192 rather than `XVECTOR (FOO)->size'.
12194 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12195 inttypes.h, as a gnulib replacement is used if it not available in
12198 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12200 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12201 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12202 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12204 * coding.c (coding_alloc_by_realloc): Error out if destination
12205 will grow beyond MOST_POSITIVE_FIXNUM.
12206 (decode_coding_emacs_mule): Abort if there isn't enough place in
12207 charbuf for the composition carryover bytes. Reserve an extra
12208 space for up to 2 characters produced in a loop.
12209 (decode_coding_iso_2022): Abort if there isn't enough place in
12210 charbuf for the composition carryover bytes.
12212 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12214 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12215 aborting when %lld or %lll format is passed.
12216 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12217 %llo or %llx format is passed. (Bug#8545)
12219 * window.c (window_scroll_line_based): Use a marker instead of
12220 simple variables to record original value of point. (Bug#7952)
12222 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12223 produced by %s or %c overflows available buffer space. (Bug#8545)
12225 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12227 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12228 (SIZE_MAX): Move defn after all includes, as they might #define it.
12230 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12232 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12234 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12236 * keyboard.c (Qdelayed_warnings_hook): Define.
12237 (command_loop_1): Run `delayed-warnings-hook'
12238 if Vdelayed_warnings_list is non-nil.
12239 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12240 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12242 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12244 * doprnt.c (doprnt): Don't return value smaller than the buffer
12245 size if the message was truncated. (Bug#8545).
12247 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12249 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12250 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12252 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12254 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12256 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12258 * makefile.w32-in: Update dependencies.
12260 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12262 Improve `doprnt' and its usage. (Bug#8545)
12263 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12264 `format_end'. Remove support for %l as a conversion specifier.
12265 Don't use xrealloc. Improve diagnostics when the %l size modifier
12266 is used. Update the commentary.
12268 * eval.c (verror): Simplify calculation of size_t.
12270 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12273 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12275 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12278 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12280 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12281 This makes this file independent of the recent pseudovector change.
12283 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12285 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12287 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12288 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12289 Remove unused local.
12290 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12292 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12293 GCC 4.6.0 optimizes based on type-based alias analysis.
12294 For example, if b is of type struct buffer * and v of type struct
12295 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12296 != &v->size, and therefore "v->size = 1; b->size = 2; return
12297 v->size;" must therefore return 1. This assumption is incorrect
12298 for Emacs, since it type-puns struct Lisp_Vector * with many other
12299 types. To fix this problem, this patch adds a new type struct
12300 vectorlike_header that documents the constraints on layout of vectors
12301 and pseudovectors, and helps optimizing compilers not get fooled
12302 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12303 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12304 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12306 (XSETPVECTYPE): Rewrite in terms of new macro.
12307 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12308 This is a bit clearer, and further avoids the possibility of
12309 undesirable aliasing.
12310 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12311 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12312 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12313 since Lisp_Subr is a special case (no "next" field).
12314 (ASIZE): Now uses header.size rather than size.
12315 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12316 to avoid the hassle of writing XVECTOR (foo)->header.size.
12317 (struct vectorlike_header): New type.
12318 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12319 object, to help avoid aliasing.
12320 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12321 (SUBRP): Likewise, since Lisp_Subr is a special case.
12322 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12323 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12324 (struct Lisp_Hash_Table): Combine first two members into a single
12325 struct vectorlike_header member. All uses of "size" and "next" members
12326 changed to be "header.size" and "header.next".
12327 * buffer.h (struct buffer): Likewise.
12328 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12329 * frame.h (struct frame): Likewise.
12330 * process.h (struct Lisp_Process): Likewise.
12331 * termhooks.h (struct terminal): Likewise.
12332 * window.c (struct save_window_data, struct saved_window): Likewise.
12333 * window.h (struct window): Likewise.
12334 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12335 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12336 * buffer.c (init_buffer_once): Likewise.
12337 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12339 * process.c (Fformat_network_address): Use local var for size,
12342 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12344 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12345 * data.c (atof): Remove decl; no longer used or needed.
12346 (digit_to_number): Move to lread.c.
12347 (Fstring_to_number): Use new string_to_number function, to be
12348 consistent with how the Lisp reader treats infinities and NaNs.
12349 Do not assume that floating-point numbers represent EMACS_INT
12350 without losing information; this is not true on most 64-bit hosts.
12351 Avoid double-rounding errors, by insisting on integers when
12352 parsing non-base-10 numbers, as the documentation specifies.
12353 * lisp.h (string_to_number): New decl, replacing ...
12354 (isfloat_string): Remove.
12355 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12356 (read1): Do not accept +. and -. as integers; this
12357 appears to have been a coding error. Similarly, do not accept
12358 strings like +-1e0 as floating point numbers. Do not report
12359 overflow for integer overflows unless the base is not 10 which
12360 means we have no simple and reliable way to continue.
12361 Break out the floating-point parsing into a new
12362 function string_to_number, so that Fstring_to_number parses
12363 floating point numbers consistently with the Lisp reader.
12364 (digit_to_number): Move here from data.c. Make it static inline.
12365 (E_CHAR, EXP_INT): Remove, replacing with ...
12366 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12367 (string_to_number): New function, replacing isfloat_string.
12368 This function checks for valid syntax and produces the resulting
12369 Lisp float number too. Rework it so that string-to-number
12370 no longer mishandles examples like "1.0e+". Use strtoumax,
12371 so that overflow for non-base-10 numbers is reported only when
12372 there's no portable and simple way to convert to floating point.
12374 * textprop.c (set_text_properties_1): Rewrite for clarity,
12375 and to avoid GCC warning about integer overflow.
12377 * intervals.h (struct interval): Use EMACS_INT for members
12378 where EMACS_UINT might cause problems. See
12379 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12380 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12381 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12383 (offset_intervals): Tell GCC not to worry about length overflow
12384 when negating a negative length.
12386 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12387 (overrun_check_free): Likewise.
12389 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12390 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12393 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12394 (gnutls_make_error): Rename local to avoid shadowing.
12395 (gnutls_emacs_global_deinit): ifdef out; not used.
12396 (Fgnutls_boot): Use const for pointer to readonly storage.
12397 Comment out unused local. Fix pointer signedness problems.
12399 * lread.c (openp): Don't stuff size_t into an 'int'.
12400 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12401 about possible signed overflow.
12403 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12404 (GDK_KEY_g): Don't define if already defined.
12405 (xg_prepare_tooltip): Avoid pointer signedness problem.
12406 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12408 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12409 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12411 * xfns.c (Fx_window_property): Simplify a bit,
12412 to make a bit faster and to avoid GCC 4.6.0 warning.
12413 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12415 * fns.c (internal_equal): Don't assume size_t fits in int.
12417 * alloc.c (compact_small_strings): Tighten assertion a little.
12419 Replace pEd with more-general pI, and fix some printf arg casts.
12420 * lisp.h (pI): New macro, generalizing old pEd macro to other
12421 conversion specifiers. For example, use "...%"pI"d..." rather
12422 than "...%"pEd"...".
12423 (pEd): Remove. All uses replaced with similar uses of pI.
12424 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12425 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12426 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12427 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12428 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12429 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12430 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12432 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12433 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12434 * print.c (safe_debug_print, print_object): Likewise.
12435 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12437 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12438 avoiding the 0 flag, which is not portable.
12439 * process.c (Fmake_network_process): Use pI to avoid cast.
12440 * region-cache.c (pp_cache): Likewise.
12441 * xdisp.c (decode_mode_spec): Likewise.
12442 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12443 behavior on 64-bit hosts with printf arg.
12444 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12445 (x_stop_queuing_selection_requests): Likewise.
12446 (x_get_window_property): Don't truncate byte count to an 'int'
12449 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12450 here, since it parses constructs like leading '-' and spaces,
12451 which are not wanted; and it overflows with large numbers.
12452 Instead, simply match F[0-9]+, which is what is wanted anyway.
12454 * alloc.c: Remove unportable assumptions about struct layout.
12455 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12456 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12457 (allocate_vectorlike, make_pure_vector): Use the new macros,
12458 plus offsetof, to remove unportable assumptions about struct layout.
12459 These assumptions hold on all porting targets that I know of, but
12460 they are not guaranteed, they're easy to remove, and removing them
12461 makes further changes easier.
12463 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12464 This doesn't fix a bug but makes the code clearer.
12465 (string_overrun_cookie): Now const. Use initializers that
12466 don't formally overflow signed char, to avoid warnings.
12467 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12468 can cause Emacs to crash when string overrun checking is enabled.
12469 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12470 multiple of sizeof (EMACS_INT); it need not be, if
12471 alignof(EMACS_INT) < sizeof (EMACS_INT).
12472 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12474 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12476 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12478 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12480 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12481 supposed to be handshaking. (Bug#8556)
12482 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12484 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12486 * lisp.h (Qdebug): List symbol.
12487 * eval.c (Qdebug): Restore global linkage.
12488 * keyboard.c (debug-on-event): New variable.
12489 (handle_user_signal): Break into debugger when debug-on-event
12490 matches the current signal symbol.
12492 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12494 * alloc.c (check_sblock, check_string_bytes)
12495 (check_string_free_list): Convert to standard C.
12497 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12499 * w32.c (emacs_gnutls_push): Fix typo.
12501 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12503 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12504 "cast to pointer from integer of different size".
12506 Improve doprnt and its use in verror. (Bug#8545)
12507 * doprnt.c (doprnt): Document the set of format control sequences
12508 supported by the function. Use SAFE_ALLOCA instead of always
12511 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12512 is one byte too soon. Don't use xrealloc; instead xfree and
12515 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12517 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12520 * gnutls.c: Renamed global_initialized to
12521 gnutls_global_initialized. Added internals for the
12522 :verify-hostname-error, :verify-error, and :verify-flags
12523 parameters of `gnutls-boot' and documented those parameters in the
12524 docstring. Start callback support.
12525 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12526 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12527 on error. Return error code.
12528 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12529 (emacs_gnutls_read): Likewise.
12530 (Fgnutls_boot): Return handshake error code.
12531 (emacs_gnutls_handle_error): New function.
12532 (wsaerror_to_errno): Likewise.

12564 <menu_help_message, prev_menu_help_message>: Constify.
12565 (IT_menu_make_room): menu->help_text is now `const char **';
12568 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
12569 to changes in oldXMenu/XMenu.h from 2011-04-16.
12570 (struct XMenu): Declare `help_text' `const char **'.

12587 changes in globals.h immediately force recompilation.
12588 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12589 $(CURDIR)/s/ms-w32.h.
12590 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
12592 * character.c (Fchar_direction): Function deleted.
12593 (syms_of_character): Don't defsubr it.
12594 <char-direction-table>: Deleted.
12596 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12598 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12599 * doprnt.c: Include limits.h.
12600 (SIZE_MAX): New macro.
12601 (doprnt): Return a size_t value. 2nd arg is now size_t.
12602 Many local variables are now size_t instead of int or unsigned.
12603 Improve overflow protection. Support `l' modifier for integer
12604 conversions. Support %l conversion. Don't assume an EMACS_INT
12605 argument for integer conversions and for %c.
12607 * lisp.h (doprnt): Restore prototype.
12609 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12610 $(SRC)/character.h.
12612 * Makefile.in (base_obj): Add back doprnt.o.
12614 * deps.mk (doprnt.o): Add back prerequisites.
12615 (callint.o): Depend on character.h.
12617 * eval.c (internal_lisp_condition_case): Include the handler
12618 representation in the error message.
12619 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12620 when breaking from the loop.
12622 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12624 * callint.c (Fcall_interactively): When displaying error message
12625 about invalid control letter, pass the character's codepoint, not
12626 a pointer to its multibyte form. Improve display of the character
12627 in octal and display also its hex code.
12629 * character.c (char_string): Use %x to display the (unsigned)
12630 codepoint of an invalid character, to avoid displaying a bogus
12633 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12634 `error', not SYMBOL_NAME itself.
12636 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12637 character arguments to `error'.
12639 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12640 to `error' in error message about FINAL_CHAR argument. Make sure
12641 FINAL_CHAR is a character, and use %c when it is passed as
12642 argument to `error'.

12832 ns_descriptor_to_entity that were caused by using free to
12833 deallocate memory blocks that were allocated by xmalloc (via
12834 xstrdup). This caused Emacs to crash when compiled with

12854 (emacs_read, emacs_write): Use it.
12855 * process.c (send_process): Adjust to the new signatures of
12856 emacs_write and emacs_gnutls_write. Do not attempt to store

13186 * lisp.h: Remove these decls.
13188 * buffer.c (buffer_count): Remove unused var.
13190 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
13191 so that it's not optimized away.
13192 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13193 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13194 exported only to the debugger.
13196 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
13197 * atimer.h (run_all_atimers): Remove; not exported.
13199 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13200 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13201 was inaccessible from Lisp.
13202 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13203 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13205 alloc.c: Import and export fewer symbols, and remove unused items.
13206 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13208 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13209 it's not optimized away by whole-program optimization.
13210 (message_enable_multibyte, free_misc): Remove.

13221 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13222 (mark_backtrace): Define only if BYTE_MARK_STACK.
13223 * xdisp.c (message_enable_multibyte): Now static.
13225 Declare Lisp_Object Q* variables to be 'static' if not exported.
13226 This makes it easier for human readers (and static analyzers)
13227 to see whether these variables are used from other modules.
13228 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13229 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

13238 Remove decls of unexported vars.
13239 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13241 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13243 Make Emacs functions such as Fatom 'static' by default.
13244 This makes it easier for human readers (and static analyzers)
13245 to see whether these functions can be called from other modules.
13246 DEFUN now defines a static function. To make the function external
13247 so that it can be used in other C modules, use the new macro DEFUE.
13248 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13249 (Finit_image_library):
13250 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13251 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13252 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13253 Remove decls, since these functions are now static.
13254 (Funintern, Fget_internal_run_time): New decls, since these functions
13255 were already external.
13257 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13258 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13264 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13265 Mark functions with DEFUE instead of DEFUN,
13266 if they are used in other modules.
13267 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13268 decls for now-static functions.
13269 * buffer.h (Fdelete_overlay): Remove decl.
13270 * callproc.c (Fgetenv_internal): Mark as internal.
13271 * composite.c (Fremove_list_of_text_properties): Remove decl.

13279 * image.c (Finit_image_library): New forward static decl.
13280 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13281 * intervals.h (Fprevious_property_change):
13282 (Fremove_list_of_text_properties): Remove decls.
13283 * keyboard.c (Fthis_command_keys): Remove decl.
13284 (Fcommand_execute): New forward static decl.
13285 * keymap.c (Flookup_key): New forward static decl.
13286 (Fcopy_keymap): Now static.
13287 * keymap.h (Flookup_key): Remove decl.
13288 * process.c (Fget_process): New forward static decl.
13289 (Fprocess_datagram_address): Mark as internal.

13300 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13302 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13305 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13307 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13308 when at ZV. (Bug#8487)
13310 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13312 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13314 * keyboard.c (parse_tool_bar_item): Likewise.
13315 * sound.c (sound_cleanup, alsa_close): Likewise.
13316 * termcap.c (tgetent): Likewise.
13317 * xfns.c (x_default_font_parameter): Likewise.
13318 * xsettings.c (read_and_apply_settings): Likewise.
13320 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13321 (overrun_check_free): Protoize.
13323 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13325 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13326 since callers should never pass a negative size.
13327 Change the signature to match that of plain 'read' and 'write'; see
13328 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13329 * lisp.h: Update prototypes of emacs_write and emacs_read.
13331 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13333 * xdisp.c (redisplay_window): Don't try to determine the character
13334 position of the scroll margin if the window start point w->startp
13335 is outside the buffer's accessible region. (Bug#8468)
13337 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13339 Fix write-region and its subroutines for buffers > 2GB.
13340 * fileio.c (a_write, e_write): Modify declaration of arguments and
13341 local variables to support buffers larger than 2GB.
13342 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13344 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13345 argument, local variables, and return value.
13347 * lisp.h: Update prototypes of emacs_write and emacs_read.
13349 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13351 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13353 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13355 Fix more problems found by GCC 4.6.0's static checks.
13357 * xdisp.c (vmessage): Use a better test for character truncation.
13359 * charset.c (load_charset_map): <, not <=, for optimization,
13360 and to avoid potential problems with integer overflow.
13361 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13362 * casetab.c (set_identity, shuffle): Likewise.
13363 * editfns.c (Fformat): Likewise.
13364 * syntax.c (skip_chars): Likewise.
13366 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13367 This also lets GCC 4.6.0 generate slightly better loop code.
13369 * callint.c (Fcall_interactively): <, not <=, for optimization.
13370 (Fcall_interactively): Count the number of arguments produced,
13371 not the number of arguments given. This is simpler and lets GCC
13372 4.6.0 generate slightly better code.
13374 * ftfont.c: Distingish more carefully between FcChar8 and char.
13375 The previous code passed unsigned char * to a functions like
13376 strlen and xstrcasecmp that expect char *, which does not
13377 conform to the C standard.
13378 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13379 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13380 char * when the C standard requires it.
13382 * keyboard.c (read_char): Remove unused var.
13384 * eval.c: Port to Windows vsnprintf (Bug#8435).
13385 Include <limits.h>.
13386 (SIZE_MAX): Define if the headers do not.
13387 (verror): Do not give up if vsnprintf returns a negative count.
13388 Instead, grow the buffer. This ports to Windows vsnprintf, which
13389 does not conform to C99. Problem reported by Eli Zaretskii.
13390 Also, simplify the allocation scheme, by avoiding the need for
13391 calling realloc, and removing the ALLOCATED variable.
13393 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13395 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13396 But keep the doprint source code for now, as we might revamp it
13397 and use it again (Bug#8435).
13398 * lisp.h (doprnt): Remove.
13399 * Makefile.in (base_obj): Remove doprnt.o.
13400 * deps.mk (doprnt.o): Remove.
13402 error: Print 32- and 64-bit integers portably (Bug#8435).
13403 Without this change, on typical 64-bit hosts error ("...%d...", N)
13404 was used to print both 32- and 64-bit integers N, which relied on
13405 undefined behavior.
13406 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13407 * lisp.h (error, verror): Mark as printf-like functions.
13408 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13409 Report overflow in size calculations when allocating printf buffer.
13410 Do not truncate output string at its first null byte.
13411 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13412 Truncate the output at a character boundary, since vsnprintf does not
13414 * charset.c (check_iso_charset_parameter): Convert internal
13415 character to string before calling 'error', since %c now has the
13417 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13418 overflow when computing char to be passed to 'error'. Do not
13419 pass Lisp_Object to 'error'; pass the integer instead.
13420 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13421 formatted with plain %d.
13423 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13425 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13427 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13429 * xterm.c (x_catch_errors): Remove duplicate declaration.
13431 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13433 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13435 2011-04-10 Jim Meyering <meyering@redhat.com>
13437 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13438 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13439 return ssize_t not "int", and use size_t as the buffer length.
13440 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13441 * gnutls.h: Update declarations.
13442 * process.c (read_process_output): Use ssize_t, to match.
13443 (send_process): Likewise.
13445 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13447 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13449 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13451 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13452 Use unsigned char, to match FcChar8 type definition.
13454 * xterm.c (handle_one_xevent):
13455 * xmenu.c (create_and_show_popup_menu):
13456 * xselect.c (x_decline_selection_request)
13457 (x_reply_selection_request): Avoid type-punned deref of X events.
13459 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13461 Fix some uses of `int' instead of EMACS_INT.
13462 * search.c (string_match_1, fast_string_match)
13463 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13464 (scan_buffer, find_next_newline_no_quit)
13465 (find_before_next_newline, search_command, Freplace_match)
13466 (Fmatch_data): Make some `int' variables be EMACS_INT.
13468 * xdisp.c (display_count_lines): 3rd argument and return value now
13469 EMACS_INT. All callers changed.
13470 (pint2hrstr): Last argument is now EMACS_INT.
13472 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13473 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13474 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

13485 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13486 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13488 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13489 (encode_invocation_designation): Last argument P_NCHARS is now
13491 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13492 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13494 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13497 * ccl.c (Fccl_execute_on_string): Declare some variables
13500 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13502 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13504 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13506 * process.c (Fformat_network_address): Doc fix.
13508 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)

13517 (syms_of_keyboard): Use DEFSYM macro.
13519 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13553 to system-supplied API.
13555 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13557 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13558 This avoids several warnings with gcc -Wstrict-overflow.
13559 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13560 directly, rather than having caller test rule sign. This avoids
13561 some unnecessary tests.
13562 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13563 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13564 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13566 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13567 (xfont_open): Avoid unnecessary tests.
13569 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13571 * composite.h, composite.c (composition_gstring_put_cache):
13572 Use EMACS_INT, not int, for length.
13574 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13575 breaking out part of COMPOSITION_DECODE_RULE.
13576 (COMPOSITION_DECODE_RULE): Use it.
13577 * composite.c (get_composition_id): Remove unused local vars,
13578 by using the new macro.
13580 * textprop.c (set_text_properties_1): Change while to do-while,
13581 since the condition is always true at first.
13583 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13584 (interval_deletion_adjustment): Return unsigned value.
13587 * process.c (list_processes_1, create_pty, read_process_output):
13588 (exec_sentinel): Remove vars that were set but not used.
13589 (create_pty): Remove unnecessary "volatile"s.
13590 (Fnetwork_interface_info): Avoid possibility of int overflow.

13603 * print.c (print_error_message): Avoid int overflow.
13605 * font.c (font_list_entities): Redo for clarity,
13606 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13608 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13609 (font_score): Avoid potential overflow in diff calculation.
13611 * fns.c (substring_both): Remove var that is set but not used.
13612 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13614 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13616 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13617 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13618 can always succeed if overflow has undefined behavior.
13620 * search.c (boyer_moore, wordify): Remove vars set but not used.
13621 (wordify): Omit three unnecessary tests.
13623 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13624 All callers changed. This avoids the need for an unused var.
13626 * casefiddle.c (casify_region): Remove var that is set but not used.
13628 * dired.c (file_name_completion): Remove var that is set but not used.
13630 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13632 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13633 (Finsert_file_contents): Remove unnecessary code checking fd.
13635 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13636 Check for integer overflow on size calculations.
13638 * buffer.c (Fprevious_overlay_change): Remove var that is set
13641 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13642 Remove vars that are set but not used.
13643 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13644 (timer_check_2): Mark vars as initialized.
13646 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13648 * image.c (lookup_image): Remove var that is set but not used.
13649 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13651 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13652 that are set but not used.
13654 * xfns.c (make_invisible_cursor): Don't return garbage
13655 if XCreateBitmapFromData fails (Bug#8410).
13657 * xselect.c (x_get_local_selection, x_handle_property_notify):
13658 Remove vars that are set but not used.
13660 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13661 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13663 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13664 Remove var that is set but not used.
13665 (scroll_bar_windows_size): Now size_t, not int.
13666 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13667 Check for overflow.
13669 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13670 (map_tty_color) [!defined MSDOS]: Likewise.
13672 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13674 * coding.c: Remove vars that are set but not used.
13675 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13676 All callers changed.
13677 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13678 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13679 (decode_coding_charset): Remove vars that are set but not used.
13681 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13682 that is set but not used.
13684 * print.c (print_object): Remove var that is set but not used.
13686 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13687 The gnulib version avoids calling malloc in the usual case,
13688 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13689 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13690 * filelock.c (current_lock_owner): Likewise.
13691 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13692 * sysdep.c: Include allocator.h, careadlinkat.h.
13693 (emacs_no_realloc_allocator): New static constant.
13694 (emacs_readlink): New function.
13695 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13696 ../lib/careadlinkat.h.
13698 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13700 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13701 first non-nil return value).
13703 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13705 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13706 if not defined (Bug#8403).
13708 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13710 * xdisp.c (display_count_lines): Remove parameter `start',
13711 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13712 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13713 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13715 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13716 and thereabouts. All callers changed.
13717 (get_per_char_metric): Remove parameter `f', unused since
13718 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13720 2011-04-02 Jim Meyering <meyering@redhat.com>
13722 do not dereference NULL upon failed strdup
13723 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13724 (ns_get_family): Likewise.
13726 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13728 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13730 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13732 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13735 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13737 Add lexical binding.
13739 * window.c (Ftemp_output_buffer_show): New fun.
13740 (Fsave_window_excursion):
13741 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13743 * lread.c (lisp_file_lexically_bound_p): New function.
13744 (Fload): Bind Qlexical_binding.
13745 (readevalloop): Remove `evalfun' arg.
13746 Bind Qinternal_interpreter_environment.
13747 (Feval_buffer): Bind Qlexical_binding.
13748 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13750 (syms_of_lread): Declare `lexical-binding'.
13752 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13754 * keyboard.c (eval_dyn): New fun.
13755 (menu_item_eval_property): Use it.
13757 * image.c (parse_image_spec): Use Ffunctionp.
13759 * fns.c (concat, mapcar1): Accept byte-code-functions.
13761 * eval.c (Fsetq): Handle lexical vars.
13762 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13763 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13764 (FletX, Flet): Obey lexical binding.
13765 (Fcommandp): Handle closures.
13766 (Feval): New `lexical' arg.
13767 (eval_sub): New function extracted from Feval. Use it almost
13768 everywhere where Feval was used. Look up vars in lexical env.
13770 (Ffunctionp): Move from subr.el.
13771 (Ffuncall): Handle closures.
13772 (apply_lambda): Remove `eval_flags'.
13773 (funcall_lambda): Handle closures and new byte-code-functions.
13774 (Fspecial_variable_p): New function.
13775 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13776 but without exporting it to Lisp.
13778 * doc.c (Fdocumentation, store_function_docstring):
13779 * data.c (Finteractive_form): Handle closures.
13781 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13784 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13786 (exec_byte_code): New function extracted from Fbyte_code to handle new
13787 calling convention for byte-code-functions. Add new byte-codes.
13789 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13791 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13793 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13795 * xdisp.c (redisplay_internal): Fix prototype.
13797 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13799 * xdisp.c (SCROLL_LIMIT): New macro.
13800 (try_scrolling): Use it when setting scroll_limit.
13801 Limit scrolling to 100 screen lines.
13802 (redisplay_window): Even when falling back on "recentering",
13803 position point in the window according to scroll-conservatively,
13804 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13806 (try_scrolling): When point is above the window, allow searching
13807 as far as scroll_max, or one screenful, to compute vertical
13808 distance from PT to the scroll margin position. This prevents
13809 try_scrolling from unnecessarily failing when
13810 scroll-conservatively is set to a value slightly larger than the
13811 window height. Clean up the case of PT below the margin at bottom
13812 of window: scroll_max can no longer be INT_MAX. When aggressive
13813 scrolling is in use, don't let point enter the opposite scroll
13814 margin as result of the scroll.
13815 (syms_of_xdisp) <scroll-conservatively>: Document the
13816 threshold of 100 lines for never-recentering scrolling.
13818 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13820 * dispextern.h (move_it_by_lines):
13821 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

13823 (message_log_check_duplicate): Remove parameters `prev_bol' and
13824 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13825 (redisplay_internal): Remove parameter `preserve_echo_area',
13826 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13828 * indent.c (Fvertical_motion):
13829 * window.c (window_scroll_pixel_based, Frecenter):
13830 Don't pass `need_y_p' to `move_it_by_lines'.
13832 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13834 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13835 steal a few bits to be more compact.
13836 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13837 Remove unneeded casts.
13839 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13841 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13843 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13844 binding" message (bug#7967).
13846 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13848 Fix more problems found by GCC 4.6.0's static checks.
13850 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13851 Remove unused local var.
13853 * editfns.c (Fmessage_box): Remove unused local var.
13855 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13856 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13857 Omit unused local vars.
13858 * window.c (shrink_windows): Omit unused local var.
13859 * menu.c (digest_single_submenu): Omit unused local var.
13860 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13861 Omit unused local var.
13863 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13864 Don't assume string length fits in int.
13865 (keyremap_step, read_key_sequence): Use size_t for sizes.
13866 (read_key_sequence): Don't check last_real_key_start redundantly.
13868 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13869 instead of alloca (Bug#8344).
13871 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13872 (Fbacktrace_frame): Don't assume nframes fits in int.
13874 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

13879 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13881 * cm.c (calccost): Turn while-do into do-while, for clarity.
13883 * keyboard.c (syms_of_keyboard): Use the same style as later
13884 in this function when indexing through an array. This also
13885 works around GCC bug 48267.
13887 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13889 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13891 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13892 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13894 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13895 This avoids undefined behavior on integer overflow, and is a bit
13896 more convenient anyway since it is compared to a size_t variable.
13898 Variadic C functions now count arguments with size_t, not int.
13899 This avoids an unnecessary limitation on 64-bit machines, which
13900 caused (substring ...) to crash on large vectors (Bug#8344).
13901 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13902 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13910 * fns.c (concat): Likewise.
13911 * frame.c (x_set_frame_parameters): Likewise.
13912 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13913 0 if not found, not -1. All callers changed.
13915 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13916 (stack_copy_size): Now size_t, not int.
13917 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13919 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13921 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13922 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13923 All callers changed.
13925 * lisp.h (multibyte_char_to_unibyte):
13926 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13927 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13935 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13937 * keyboard.c (safe_run_hook_funcall): New function.
13938 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13939 don't set the hook to nil, but remove the offending function instead.
13940 (Qcommand_hook_internal): Remove, unused.
13941 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13942 Vcommand_hook_internal.
13944 * eval.c (enum run_hooks_condition): Remove.
13945 (funcall_nil, funcall_not): New functions.
13946 (run_hook_with_args): Call each function through a `funcall' argument.
13947 Remove `cond' argument, now redundant.
13948 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13949 (Frun_hook_with_args_until_failure): Adjust accordingly.
13950 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
13952 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

13956 * print.c (strout): Remove parameter `multibyte', unused since
13957 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13959 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13960 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13961 All callers changed.
13963 * w32.c (_wsa_errlist): Use braces for struct initializers.

14122 * buffer.c (Fkill_all_local_variables):
14123 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14125 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14126 unconditionally since it does the check itself.
14128 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14130 Fix more problems found by GCC 4.5.2's static checks.
14132 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14133 the first time through the loop, since we know p0 < p1 then.
14134 This also avoids a gcc -Wstrict-overflow warning.
14136 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14137 leading to a memory leak, possible in functions like
14138 load_charset_map_from_file that can allocate an unbounded number
14139 of objects (Bug#8318).
14141 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14142 that could (at least in theory) be that large.
14144 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14145 This is less likely to overflow, and avoids undefined behavior if
14146 overflow does occur. All callers changed. Use strtoul to scan
14147 for the unsigned long integer.
14148 (pint2hrstr): Simplify and tune code slightly.
14149 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14164 * process.c (Fmake_network_process): Use socklen_t, not int,
14165 where POSIX says socklen_t is required in portable programs.
14166 This fixes a porting bug on hosts like 64-bit HP-UX, where
14167 socklen_t is wider than int (Bug#8277).
14168 (Fmake_network_process, server_accept_connection):
14169 (wait_reading_process_output, read_process_output):
14172 * process.c: Rename or move locals to avoid shadowing.

14182 Make tparam.h and terminfo.c consistent.
14183 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14184 Include tparam.h instead, since it declares them.
14185 * cm.h (PC): Remove extern decl; tparam.h now does this.
14186 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14187 * terminfo.c: Include tparam.h, to check interfaces.
14188 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14189 (tparam): Adjust signature to match interface in tparam.h;
14190 this removes some undefined behavior. Check that outstring and len
14191 are zero, which they always are with Emacs.
14192 * tparam.h (PC, BC, UP): New extern decls.
14194 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14195 (xftfont_open): Rename locals to avoid shadowing.

14212 (find_automatic_composition, composition_adjust_point): Likewise.
14213 (composition_update_it): Mark var as initialized.
14214 (find_automatic_composition): Mark vars as initialized,
14215 with a FIXME (Bug#8290).

14220 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14221 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14222 to avoid shadowing.

14234 Fix pointer signedness.
14235 (alsa_choose_format): Remove unused local var.
14236 (wav_play): Initialize a variable to 0, to prevent undefined
14237 behavior (Bug#8278).
14239 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14241 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14243 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14244 clobbering (Bug#8298).
14245 * sysdep.c (sys_subshell): Likewise.
14246 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14248 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14249 This should get cleaned up, so that child_setup has the
14250 same signature on all platforms.
14252 * callproc.c (call_process_cleanup): Now static.
14253 (relocate_fd): Rename locals to avoid shadowing.
14255 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14257 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14258 not to be necessary, and produces flickering.
14260 2011-03-20 Glenn Morris <rgm@gnu.org>
14262 * config.in: Remove file.
14264 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

14309 Define only if needed.
14311 * unexelf.c (unexec): Name an expression,
14312 to avoid gcc -Wbad-function-cast warning.
14313 Use a different way to cause a compilation error if anyone uses
14314 n rather than nn, a way that does not involve shadowing.
14315 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14317 * deps.mk (unexalpha.o): Remove; unused.

14419 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14421 Use functions, not macros, for up- and down-casing (Bug#8254).
14422 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14423 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14424 to use the following functions instead of these macros.
14425 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14426 EMACS_INT, since callers assume the returned value fits in int.
14427 (upcase1): Likewise, for UPCASE_TABLE.
14428 (uppercasep, lowercasep, upcase): New static inline functions.
14429 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14430 the race-condition problem in the old DOWNCASE.
14432 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
14433 Rename locals to avoid shadowing.
14434 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14435 (regex_compile, re_search_2, re_match_2_internal):
14436 Remove unused local vars.
14437 (FREE_VAR): Rewrite so as not to use empty "else",
14438 which gcc can warn about.
14439 (regex_compile, re_match_2_internal): Mark locals as initialized.
14440 (RETALLOC_IF): Define only if needed.
14441 (WORDCHAR_P): Likewise. This one is never needed, but is used
14442 only in a comment talking about a compiler bug, so put inside
14443 the #if 0 of that comment.
14444 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14445 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14448 * search.c (boyer_moore): Rename locals to avoid shadowing.
14449 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

14460 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
14462 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14463 Rename locals to avoid shadowing.
14464 (Fvertical_motion): Mark locals as initialized.
14466 * casefiddle.c (casify_object, casify_region): Now static.
14467 (casify_region): Mark local as initialized.
14469 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14471 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14472 New macros, so that the caller can use some names other than
14473 gcpro1, gcpro2, etc.
14474 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14476 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14477 argument, for consistency with GCPRO2_VAR, etc: it is now the
14478 prefix of the variable, not the variable itself. All uses
14480 * dired.c (directory_files_internal, file_name_completion):
14481 Rename locals to avoid shadowing.
14483 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14484 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14485 dired.c's scmp function, had undefined behavior.
14486 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14487 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14488 * buffer.h: ... to here, because these macros use current_buffer,
14489 and the new implementation with inline functions needs to have
14490 current_buffer in scope now, rather than later when the macros
14492 (downcase, upcase1): New static inline functions.
14493 (DOWNCASE, UPCASE1): Reimplement using these functions.
14494 This avoids undefined behavior in expressions like
14495 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14496 from race conditions in accessing the global variables
14497 case_temp1 and case_temp2.
14498 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14499 * lisp.h (case_temp1, case_temp2): Remove their decls.
14500 * character.h (ASCII_CHAR_P): Move from here ...
14501 * lisp.h: ... to here, so that the inline functions mentioned
14502 above can use them.
14504 * dired.c (directory_files_internal_unwind): Now static.
14506 * fileio.c (file_name_as_directory, directory_file_name):
14507 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14509 (file_name_as_directory): Use const pointers when appropriate.
14510 (Fexpand_file_name): Likewise. In particular, newdir might
14511 point at constant storage, so make it a const pointer.
14512 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14513 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14515 (Fset_file_times, Finsert_file_contents, auto_save_error):

14520 to avoid shadowing.
14522 * marker.c (bytepos_to_charpos): Remove; unused.
14524 * lisp.h (verify_bytepos, count_markers): New decls,
14525 so that gcc does not warn that these functions aren't declared.
14527 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14528 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14529 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14530 (copy_text): Remove unused local var.
14532 * filelock.c (within_one_second): Now static.
14533 (lock_file_1): Rename local to avoid shadowing.
14535 * buffer.c (fix_overlays_before): Mark locals as initialized.
14536 (fix_start_end_in_overlays): Likewise. This function should be
14537 simplified by using pointers-to-pointers, but that's a different
14539 (switch_to_buffer_1): Now static.
14540 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14541 (report_overlay_modification): Rename locals to avoid shadowing.
14543 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14544 Fix pointer signedness issue.
14545 (sys_subshell): Mark local as volatile if checking for lint,
14546 to suppress a gcc -Wclobbered warning that does not seem to be right.
14547 (MAXPATHLEN): Define only if needed.
14549 * process.c (serial_open, serial_configure): Move decls from here ...
14550 * systty.h: ... to here, so that they can be checked.
14552 * fns.c (get_random, seed_random): Move extern decls from here ...
14553 * lisp.h: ... to here, so that they can be checked.
14555 * sysdep.c (reset_io): Now static.
14556 (wait_for_termination_signal): Remove; unused.
14558 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14559 (copy_keymap_item, append_key, push_text_char_description):
14561 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14562 (DENSE_TABLE_SIZE): Remove; unused.
14563 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14564 (describe_map_tree):
14565 Rename locals to avoid shadowing.
14567 * keyboard.c: Declare functions static if they are not used elsewhere.

14716 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14717 reports time overflow. See
