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

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

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

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

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

221 GetFileAttributes fails with network-related error codes.
222 (sys_rename): Diagnose renaming of a symlink when the user doesn't
223 have the required privileges.
224 (get_file_security_desc_by_name): Renamed from
225 get_file_security_desc.

227 with addition of handling of symlinks and support for 'lstat'. If
228 possible, get file's attributes and security information by
229 handle, not by name. Produce S_IFLNK bit for symlinks, when
231 (stat, lstat): New functions, call 'stat_worker'.
232 (symlink, readlink, careadlinkat): Rewritten to create and resolve
233 symlinks when the underlying filesystem supports them.
235 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
237 Fix macroexp crash on Windows with debugging (Bug#12118).
238 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
239 checking subscripts; problem introduced with the recent
240 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
241 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
242 since it's used in non-static inline functions now.
244 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
245 Don't assume buffer size fits in 'int'. Remove unused local.
247 Use C99-style 'extern inline' if available.
248 * buffer.h (BUFFER_INLINE):
249 * category.h (CATEGORY_INLINE):
250 * character.h (CHARACTER_INLINE):
251 * charset.h (CHARSET_INLINE):

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

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

554 does that unconditionally. Remove file, which is now empty.
556 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
559 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

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

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

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

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

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

804 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
805 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
806 not be usable in #if. This simplifies things.
808 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
810 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
812 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

815 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
816 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
817 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
818 Adjust to changes in lisp.h and emacs.c, by using
819 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
820 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
821 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
822 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
823 instead of gdb_valbits.
824 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
825 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
826 instead of gdb_array_mark_flag.
827 (xboolvector): Get size from $->size, not $->header.size.
828 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
829 (xreload, hook-run, hookpost-run): Remove.
830 * emacs.c: Include <verify.h>.
831 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
832 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
834 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
835 (gdb_USE_LSB_TAG): New enum constants.
836 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
837 Also define these as enum constants, so they're visible to GDB.
838 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
839 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
840 as constants, so they're visible to GDB.
841 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
842 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
843 Now enum constants, not macros, so they're visible to GDB.
844 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
845 more convenient now. All uses changed.
846 (VALMASK) [USE_LSB_TAG]: Also define in this case.

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

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

902 or invalid. (Bug#12025)
904 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
905 it signals an error when a tooltip frame is being created.
907 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

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

1681 * s/aix4-2.h (unix): Remove; no longer needed.
1683 EMACS_TIME simplification (Bug#11875).
1684 This replaces macros (which typically do not work in GDB)

1686 The functional style also makes code easier to read and maintain.
1687 * systime.h: Include <sys/time.h> on all hosts, not just if
1688 WINDOWSNT, since 'struct timeval' is needed in general.

1726 * nsterm.m: Include <ftoastr.h>.
1728 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1729 Prefer snprintf to strncpy.
1730 * nsterm.m (ns_term_init):
1731 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1732 * nsterm.m (ns_term_init):
1733 Avoid the need for strncpy, by using build_string or
1734 make_unibyte_string directly. Use dtoastr, not snprintf.
1735 * process.c (Fmake_network_process): Diagnose service names that
1736 are too long, rather than silently truncating them or creating
1737 non-null-terminated names.

1754 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1755 where argument type is known to be a Lisp_Cons.

1771 the function is called with compile-time constant argument.
1772 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1773 argument, adjust users accordingly. Use build_pure_c_string where

1807 We include usg5-4-common.h, which defines them both.
1809 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1810 O_RDONLY already includes it).
1812 Stop ns builds setting the EMACSLOADPATH environment variable.
1813 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1814 Now it does not set EMACSLOADPATH, just returns the load-path string.
1815 * nsterm.h: Update accordingly.
1816 * lread.c [HAVE_NS]: Include nsterm.h.
1817 (init_lread) [HAVE_NS]: Use ns_load_path.

1827 (ns_init_paths): Do not set EMACSPATH.
1828 * nsterm.h (ns_exec_path): Add it.
1829 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1832 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1834 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1836 * process.c (wait_reading_process_output): 'waitchannels' was unset
1837 when read_kbd || !NILP (wait_for_cell); fix this.
1839 Add GCC-style 'const' attribute to functions that can use it.
1840 * character.h (char_resolve_modifier_mask):
1841 * keyboard.h (make_ctrl_char):
1842 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1843 (init_character_once, next_almost_prime, init_fns, init_image)
1844 (flush_pending_output, init_sound):

1849 Declare the dummy function with ATTRIBUTE_CONST.
1850 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1851 Add decls with ATTRIBUTE_CONST.
1853 Minor improvements to make_formatted_string.
1854 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1855 where int is good enough, as vsprintf returns an int.
1856 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1858 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1860 Use make_formatted_string to avoid double length calculation.
1861 * lisp.h (make_formatted_string): New prototype.
1862 * alloc.c (make_formatted_string): New function.
1863 * buffer.c (Fgenerate_new_buffer_name): Use it.

1866 * filelock.c (get_boot_time): Likewise.
1867 * frame.c (make_terminal_frame, set_term_frame_name)
1868 (x_report_frame_params): Likewise.
1869 * image.c (gs_load): Likewise.

1881 * nsterm.h (ns_etc_directory): Add it.
1882 * callproc.c [HAVE_NS]: Include nsterm.h.
1883 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1885 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1887 Move marker debugging code under MARKER_DEBUG.
1888 * marker.c (MARKER_DEBUG): Move marker debugging code under
1889 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1890 for bootstrap with --enable-checking (~3x slowdown reported
1891 by Juanma Barranquero <lekktu@gmail.com>).
1892 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1894 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1896 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1897 See <http://bugs.gnu.org/11825#29>.
1899 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1901 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1902 has no font, use the frame's font. (Bug#11813)
1903 (display_line): Add commentary about displaying truncation glyphs
1905 (produce_special_glyphs): Move here from term.c.
1907 * term.c (produce_special_glyphs): Move to xdisp.c.
1909 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1912 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1914 * xdisp.c (display_line): Avoid warning about implicit declaration
1917 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1919 * lisp.h: Remove empty conditional.
1921 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1923 * lread.c (load_path_check): Now static.
1925 Fix some minor --with-ns problems found by static checking.
1926 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1927 (x_set_font) [!HAVE_X_WINDOWS]:
1928 * image.c (xpm_load_image) [HAVE_NS]:
1929 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1930 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1931 Remove unused local.
1932 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1933 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1934 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1935 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1936 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1937 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1938 Fix pointer signedness problem.
1939 * xfaces.c (FRAME_X_FONT_TABLE):
1940 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1942 2012-07-07 Glenn Morris <rgm@gnu.org>
1944 * lread.c (load_path_check): New function, split from init_lread.
1945 (init_lread): Reorganize. Motivation:
1946 If EMACSLOADPATH is set, check/warn about that rather than the
1947 defaults, which we are not going to use. Hence we can remove
1948 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1949 Don't warn if site-lisp directories are missing.
1950 If not installed, start from a blank load-path, since
1951 PATH_LOADSEARCH refers to the eventual installation directories.
1953 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1955 Support truncation and continuation glyphs on GUI frames, when
1956 fringes are disabled. (Bug#11832)
1957 * xdisp.c (init_iterator): Get dimensions of truncation and
1958 continuation glyphs even if on GUI frames. Adjust
1959 it->last_visible_x on GUI frames when the left or right fringes,
1960 or both, are absent.
1961 (start_display, move_it_in_display_line_to): Handle the case of a
1962 GUI frame without a fringe to display continuation or truncation
1964 (insert_left_trunc_glyphs): Support GUI frames: make sure
1965 truncation glyphs overwrite enough glyphs from the current line to
1966 have sufficient space in pixels.
1967 (display_line): Support truncation and continuation glyphs on GUI
1968 frames. If some spare pixels are left on the line after inserting
1969 the truncation glyphs, fill that space with a stretch glyph of a
1970 suitably computed width.
1972 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1973 produce_glyphs, to support GUI sessions.
1975 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1977 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1979 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1981 Do not require float-time's arg to fit in time_t (Bug#11825).
1982 This works better on hosts where time_t is unsigned, and where
1983 float-time is applied to the (negative) difference between two times.
1984 * editfns.c (decode_time_components): Last arg is now double *,
1985 not int *, and means to store all the result as a double, without
1986 worrying about whether the seconds part fits in time_t.
1987 All callers changed.
1988 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1989 All callers changed.
1990 (Ffloat_time): Do not fail merely because the specified time falls
1991 outside of time_t range.
1993 2012-07-07 Glenn Morris <rgm@gnu.org>
1995 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2001 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2002 Update dependencies.
2004 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2006 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

2010 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2011 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2012 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2013 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2015 * xfont.c (compare_font_names): Redo to omit the need for casts.
2017 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2019 * xfns.c (Fx_change_window_property): Doc fix.
2020 * w32fns.c (Fx_change_window_property): Doc fix.
2022 * w32fns.c (Fx_window_property): Accept the same arguments as the
2023 X Windows version. Doc fix.
2024 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2026 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2027 Eli Zaretskii <eliz@gnu.org>
2029 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2030 Windows-specific code from nt/config.nt moved here.
2031 Obsolete settings removed.
2033 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2035 * process.c: Avoid unnecessary calls to gettime.
2036 (wait_reading_process_output): Don't get the time of day
2037 when gobbling data immediately and not waiting, as there's no need
2038 for it in that case. This removes a FIXME.
2040 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2042 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2043 is defined (Bug#11768).
2045 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2047 Fix marker debugging code.
2048 * marker.c (byte_char_debug_check): Do not perform the check
2049 if buffer is not multibyte.
2050 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2051 Call byte_char_debug_check with correct arguments.
2053 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2055 Compile marker debugging code only if ENABLE_CHECKING is defined.
2056 * marker.c (byte_char_debug_check, count_markers):
2057 Use only if ENABLE_CHECKING is defined.
2058 (byte_debug_flag): Remove.
2059 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2060 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2062 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2064 Avoid code repetition in marker-related functions.
2065 * marker.c (attach_marker): New function.
2066 (Fset_marker, set_marker_restricted, set_marker_both)
2067 (set_marker_restricted_both): Use it.
2068 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2069 Consistently rename charno to charpos.
2070 (marker_position): Add eassert.
2071 (marker_byte_position): Convert to eassert.

2086 * editfns.c (buildmark): Remove.
2087 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2088 (save_restriction_save): Use build_marker.
2089 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2090 * window.c (save_window_save): Likewise.
2092 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2094 Do not use Fdelete_overlay in delete_all_overlays
2095 to avoid redundant calls to unchain_overlay.
2096 * buffer.c (drop_overlay): New function.
2097 (delete_all_overlays, Fdelete_overlay): Use it.
2098 * minibuf.c (get_minibuffer): Fix comment.
2100 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2102 Port to OpenBSD 5.1 amd64.
2103 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2104 This is needed for OpenBSD, and should be harmless on all BSD systems.
2105 Also, include <sys/sysctl.h>, as it should be available on all
2106 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2107 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2108 use p_pid member, not kp_proc.pid.
2110 2012-07-06 Glenn Morris <rgm@gnu.org>
2112 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2114 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2116 More xmalloc and related cleanup.
2117 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2118 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2121 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2122 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2123 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2124 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2125 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2127 Omit needless casts involving void * pointers and allocation.
2128 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2129 as the former is more robust if P's type is changed.
2130 Prefer xzalloc to xmalloc + memset 0.
2131 Simplify malloc-or-realloc to realloc.
2132 Don't worry about xmalloc returning a null pointer.
2133 Prefer xstrdup to xmalloc + strcpy.
2134 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2136 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2137 alloca of a constant.
2139 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2141 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2142 hscroll is larger than the line width. Fixes long and futile
2143 looping inside extend_face_to_end_of_line (on a TTY) producing
2144 glyphs that are not needed and thrown away.
2146 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2148 * marker.c (set_marker_restricted_both): Simplify by using

2163 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2164 (update_theme_scrollbar_width, xg_create_scroll_bar):
2165 Use gtk_scrollbar_new (Bug#11768).

2167 (is_box_type): New function (Bug#11768).
2168 (xg_tool_item_stale_p): Call is_box_type.
2169 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2170 with default display (Bug#11768).
2172 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2174 * xdisp.c (window_hscroll_limited): New function.
2175 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2176 coordinates when window's hscroll is set to insanely large
2179 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2181 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2248 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2249 This should be fixed in a better way; see Eli Zaretskii in
2250 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2251 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2253 * fileio.c (time_error_value): Rename from special_mtime.
2254 The old name's problems were noted by Eli Zaretskii in
2255 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2257 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2258 This variable's comment says Emacs needs at least one GDB-visible
2259 symbol of type enum pvec_type, to work around GDB problems.
2260 The symbol's value doesn't matter.
2262 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2263 that causes compilation to fail on pre-C99 compilers.
2265 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2267 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

2287 * emacs.c (gdb_pvec_type): Update type.
2288 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2289 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2290 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2291 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2292 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2293 abusing vector->header.next.nbytes.
2294 (live_vector_p): Use PVEC_TYPE.
2295 (mark_object): Adapt code to extract pvectype. Use switch.
2297 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2299 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2300 Tighten new eassert a bit.
2302 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2304 Fix compilation with --enable-gcc-warnings and -O1
2306 * doprnt.c (doprnt): Change type of tem to int, initialize
2307 to avoid compiler warning. Add eassert.
2308 * search.c (simple_search): Initialize match_byte to avoid
2309 compiler warning. Add eassert.
2311 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2313 Avoid weird behavior with large horizontal scrolls.
2314 Without this change, for example, large hscroll values would
2315 mess up Emacs's display on Fedora 15 x86, presumably due to
2316 overflows in int calculations in the display code.
2317 Also, if buffers had long lines, Emacs would freeze.
2318 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2319 (set_window_hscroll): New function, containing the old guts of
2320 Fset_window_hscroll. Return the clipped value.
2321 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2322 This avoids the need to check against PTRDIFF_MAX.
2324 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2326 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2328 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2330 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2332 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2333 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2334 since GCC 4.4.6 issues a bogus warning for them.
2336 Fix bugs in file timestamp newness comparisons.
2337 * fileio.c (Ffile_newer_than_file_p):
2338 * lread.c (Fload): Use full timestamp resolution of files,
2339 not just the 1-second resolution, so that files that are only
2340 slightly newer still count as newer.
2341 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2342 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2344 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2346 * fileio.c: Improve handling of file time marker. (Bug#11852)
2347 (special_mtime): New function.
2348 (Finsert_file_contents, Fverify_visited_file_modtime):
2349 Use it to set special mtime values consistently.
2351 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2353 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2354 marker for non-existing file. (Bug#11852)
2356 2012-07-03 Glenn Morris <rgm@gnu.org>
2358 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2359 and did not make it into globals.h).
2361 2012-07-03 Tom Tromey <tromey@redhat.com>
2363 * window.c (Fset_window_margins, Fset_window_fringes)
2364 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2365 * textprop.c (Fprevious_property_change): No longer static.
2366 * syntax.c (Fsyntax_table_p): No longer static.
2367 * process.c (Fget_process, Fprocess_datagram_address): No longer

2377 * doc.c (Fdocumentation_property, Fsnarf_documentation):
2379 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
2381 * dired.c (Ffile_attributes): No longer static.
2382 * composite.c (Fcomposition_get_gstring): No longer static.
2383 * callproc.c (Fgetenv_internal): No longer static.
2385 * ccl.h: Remove EXFUNs.
2386 * buffer.h: Remove EXFUNs.
2387 * dispextern.h: Remove EXFUNs.
2388 * intervals.h: Remove EXFUNs.
2389 * fontset.h: Remove EXFUN.
2390 * font.h: Remove EXFUNs.
2391 * dosfns.c (system_process_attributes): Remove EXFUN.
2392 * keymap.h: Remove EXFUNs.
2393 * lisp.h: Remove EXFUNs.
2394 * w32term.h: Remove EXFUNs.
2395 * window.h: Remove EXFUNs.
2396 * xsettings.h: Remove EXFUN.
2397 * xterm.h: Remove EXFUN.
2399 2012-07-03 Glenn Morris <rgm@gnu.org>
2401 * lisp.h (Frandom): Make it visible to C.
2402 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2403 buffer for invisible buffers. (Bug#1229)
2405 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2407 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2408 values which aren't power of 2.
2409 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2410 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2413 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2415 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2417 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2419 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2421 * alloc.c (allocate_vector_block): Remove redundant
2422 calls to mallopt if DOUG_LEA_MALLOC is defined.
2423 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2424 avoid calls to mallopt if zero_vector is returned.
2426 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2428 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2429 is enabled, avoid dereferencing NULL current_sblock if
2432 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2434 Cleanup basic buffer management.
2435 * buffer.h (struct buffer): Change layout to use generic vector
2436 marking code. Fix some comments. Change type of 'clip_changed'
2437 to bitfield. Remove unused #ifndef old.
2438 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2439 (GET_OVERLAYS_AT): Fix indentation.
2440 (for_each_per_buffer_object_at): New macro.
2441 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2442 (Fbuffer_local_variables): Use it.
2443 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2444 * alloc.c (allocate_buffer): Adjust to match new layout of
2445 struct buffer. Fix comment.
2446 (mark_overlay): New function.
2447 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2448 Lisp area of struct buffer.
2449 (mark_object): Use it. Adjust marking of misc objects
2450 and related comments.
2452 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2454 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2455 wrapper that is not needed because the wrapped code is a no-op (zero
2456 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2457 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2459 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2461 * alloc.c (mark_buffer): Simplify. Remove prototype.
2462 (mark_object): Add comment. Reorganize marking of vector-like
2463 objects. Use CHECK_LIVE for all vector-like objects except buffers
2464 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2465 redundant calls to mark_vectorlike for bool vectors.
2467 2012-06-30 Glenn Morris <rgm@gnu.org>
2469 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2471 * epaths.in (PATH_SITELOADSEARCH): New.
2472 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2473 This is rather than relying on --enable-locallisppath elements
2474 having "site-lisp" in their names. (Bug#10208#25, 11658)
2476 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2478 * w32proc.c (sys_select): Accept and ignore one more argument.
2480 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2482 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2483 (pselect) [!MS_DOS]: Redirect to sys_select.
2485 * sysdep.c: Don't include dos.h and dosfns.h.
2487 * process.c (sys_select):
2488 * msdos.c (sys_select): Accept one more argument and ignore it.
2490 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2491 adapt data types and code to that.
2494 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2495 which clashes with the gnulib function of the same name.
2497 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2499 * font.c (font_style_to_value, font_style_symbolic)
2500 (font_prop_validate_style): Add type checks for values in
2503 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2505 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2508 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2510 * xdisp.c (try_window_id): Undo last change.
2512 * w32.c (getwd): Adjust commentary about startup_dir.
2513 (init_environment): Always call sys_access, even in non-MSVC
2514 builds. Don't chdir to the directory of the Emacs executable.
2515 This undoes code from 1997 which was justified by the need to
2516 "avoid conflicts when removing and renaming directories". But its
2517 downside was that every relative file name was being interpreted
2518 relative to the directory of the Emacs executable, which can never
2519 be TRT. In particular, it broke sys_access when called with
2520 relative file names.
2521 (sys_access): Map GetLastError to errno.
2523 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2525 * window.h (struct window): Change type of 'fringes_outside_margins'
2526 to bitfield. Fix comment. Adjust users accordingly.

2529 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2532 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2534 * gnutls.c (emacs_gnutls_handshake):
2535 Add QUIT to make the loop interruptible.
2537 2012-06-29 Glenn Morris <rgm@gnu.org>
2539 * charset.c (init_charset): Make lack of etc/charsets fatal.
2541 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2543 * editfns.c (region_limit): Fix type mismatch.
2545 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2547 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2548 undefined. Convert from xassert to eassert.
2549 * nsmenu.m: Convert from xassert to eassert.
2550 * nsterm.m: Likewise.
2552 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2554 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2556 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2558 Avoid integer overflow on scroll-left and scroll-right.
2559 * window.c (HSCROLL_MAX): New macro.
2560 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2561 overflow when requested scroll falls outside ptrdiff_t range.
2563 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2565 * window.h (struct window): Change type of 'hscroll',
2566 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2567 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2568 Adjust users accordingly.
2569 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2570 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2571 from EMACS_INT to ptrdiff_t.
2572 (make_window): Omit redundant initialization.
2574 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2578 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2580 * window.h (struct window): Change type of 'use_time' and

2591 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2592 adjust comments accordingly.

2641 * alloc.c (allocate_string_data): Remove dead code.
2642 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2643 avoid GCC warning about unused macro.
2645 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2647 * alloc.c (allocate_string): Omit intervals initialization.
2648 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2649 as in make_pure_string and make_pure_c_string.
2651 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2653 * alloc.c (allocate_string): Fix last change.
2655 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2693 * frame.c (make_frame): Omit redundant initialization.

2705 * alloc.c: Remove build_string.
2706 * lisp.h: Define build_string as static inline. This provides
2707 a better opportunity to optimize away calls to strlen when the
2708 function is called with compile-time constant argument.
2709 * image.c (imagemagick_error): Convert to build_string.
2710 * w32proc.c (sys_spawnve): Likewise.
2711 * xterm.c (x_term_init): Likewise.
2713 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2715 Use sprintf return value instead of invoking strlen on result.
2716 In the old days this wasn't portable, since some sprintf
2717 implementations returned char *. But they died out years ago and
2718 Emacs already assumes sprintf returns int.
2719 Similarly for float_to_string.
2720 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2721 * ccl.c (ccl_driver):
2722 * character.c (string_escape_byte8):

2725 * print.c (print_object):
2726 * xdisp.c (message_dolog):
2727 * xfns.c (syms_of_xfns):
2728 Use sprintf or float_to_string result to avoid need to call strlen.
2729 * data.c (Fnumber_to_string):
2730 Use make_unibyte_string, since the string must be ASCII.
2731 * lisp.h, print.c (float_to_string): Now returns int length.
2732 * term.c (produce_glyphless_glyph):
2733 Use sprintf result rather than recomputing it.
2735 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2736 * Makefile.in (ALL_CFLAGS):
2737 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2743 strcasecmp if available.

2759 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
2761 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2762 sprintf already null-terminates its output.

2766 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2768 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2771 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2773 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2774 instead of truncating it to 63 (admittedly a generous limit).
2776 * process.c: Fix spelling and caps in comments.
2778 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2780 * emacs.c (setpgrp): Remove definition, unused.

2790 (SYSTIME_H): Add nt/inc/sys/time.h.
2792 * systime.h [WINDOWSNT]: Include sys/time.h.

2904 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2906 Support higher-resolution time stamps (Bug#9000).
2907 The time stamps are only nanosecond-resolution at the C level,
2908 since that's the best that any real-world system supports now.
2909 But they are picosecond-resolution at the Lisp level, as that's
2910 easy, and leaves room for future OS improvements.
2912 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2915 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2916 Don't get current time unless it's needed.
2918 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2919 now provides it if it's absent.
2920 (start_atimer): Port to higher-res time stamps.
2921 Check for time stamp overflow. Don't get current time more
2922 often than is needed.
2924 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2925 Include systime.h, not time.h.
2926 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2928 * dired.c: Include stat-time.h.
2929 (Ffile-attributes): File times now have higher resolution.

2932 (struct image): Timestamp now has higher resolution.
2934 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2935 has at least microseconds now. All uses removed.
2936 (update_frame, update_single_window, update_window, update_frame_1)
2937 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2939 * editfns.c (time_overflow): Now extern.
2940 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2941 (float-time, Fformat_time_string, Fcurrent_time_string)
2942 (Fcurrent_time_zone): Accept and generate higher-resolution

2945 (decode_time_components, lisp_seconds_argument): New functions.
2946 (make_time): Now static.
2947 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2948 Report an error if the time is invalid, rather than having the caller
2951 * fileio.c: Include <stat-time.h>
2952 (Fcopy_file): Copy higher-resolution time stamps.
2953 Prefer to set the time stamp via a file descriptor if that works.
2954 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2955 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2956 (Fvisited_file_modtime, Fset_visited_file_modtime):
2957 Support higher-resolution time stamps.
2959 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2961 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2963 * image.c (prepare_image_for_display, clear_image_cache)
2964 (lookup_image): Port to higer-resolution time stamps.
2966 * keyboard.c (start_polling, bind_polling_period):
2967 Check for time stamp overflow.
2968 (read_char, kbd_buffer_get_event, timer_start_idle)
2969 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2970 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2971 Port to higher-resolution time stamps. Do not assume time_t is signed.
2972 (decode_timer): New function. Timers are now vectors of length 9,
2973 not 8, to accommodate the picosecond component.
2974 (timer_check_2): Use it.
2976 * nsterm.m (select_timeout, timeval_subtract): Remove.
2977 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2978 as they're a bit more accurate and handle overflow better.
2979 (ns_select): Change prototype to be compatible with pselect.
2980 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2981 * nsterm.h (ns_select): Adjust prototype.
2983 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2984 us-resolution time stamps.
2985 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2987 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2989 * lisp.h (time_overflow): New decl.
2990 (wait_reading_process_output): First arg is now intmax_t, not int,
2991 to accommodate larger waits.
2993 * process.h (struct Lisp_Process.read_output_delay):
2994 Now counts nanoseconds, not microseconds.
2995 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2997 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2998 (wait_reading_process_output):
2999 Port to ns-resolution time stamps.
3000 (Faccept_process_output, wait_reading_process_output):
3001 Check for time stamp overflow. Do not assume time_t is signed.
3002 (select_wrapper): Remove; we now use pselect.
3003 (Fprocess_attributes): Now generates ns-resolution time stamps.
3005 * sysdep.c: Include utimens.h. Don't include utime.h
3006 or worry about struct utimbuf; gnulib does that for us now.
3007 (gettimeofday): Remove; gnulib provides a substitute.
3008 (make_timeval): New function.
3009 (set_file_times): Now sets ns-resolution time stamps.
3010 New arg FD; all uses changed.
3011 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3012 (system_process_attributes):
3013 Now returns ns-resolution time stamp. All uses changed.
3014 Check for time stamp overflow.
3016 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3017 provides a substitute now.
3019 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3020 since it guarantees struct timespec.
3021 (EMACS_TIME): Now struct timespec, so that we can support
3022 ns-resolution time stamps.
3023 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3024 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3025 (EMACS_USECS): Remove.
3026 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3027 so multiply the arg by 1000 before storing it.
3028 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3030 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3031 Port to ns-resolution time stamps.
3032 (EMACS_TIME_NEG_P): Remove; replaced by....
3033 (EMACS_TIME_SIGN): New macro.
3034 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3035 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3036 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3037 (make_timeval, make_lisp_time, decode_time_components): New decls.
3038 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3039 that it mishandled time_t overflow. You can't compare by subtracting!
3040 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3041 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3043 * term.c: Include <sys/time.h>.
3044 (timeval_to_Time): New function, for proper overflow wraparound.
3045 (term_mouse_position, term_mouse_click): Use it.
3047 * undo.c (record_first_change): Support higher-resolution time stamps
3049 (Fprimitive_undo): Use them when restoring time stamps.
3051 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3052 (w32_get_internal_run_time):
3053 Port to higher-resolution Emacs time stamps.
3054 (ltime): Now accepts single 64-bit integer, as that's more convenient
3057 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3059 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3060 for compatibility with pselect. Support ns-resolution time stamps.
3062 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3064 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3065 Check for time stamp overflow, and support ns-resolution time stamps.
3067 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3068 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3069 (timeval_subtract): Remove; no longer needed.
3070 (XTflash, XTring_bell, x_wait_for_event):
3071 Port to ns-resolution time stamps. Don't assume time_t is signed.
3073 2012-06-22 Chong Yidong <cyd@gnu.org>

3077 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3079 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3080 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3081 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3082 staticidx goes up to 1597 out of 1600 = 0x640.)
3084 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3086 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3087 Otherwise, the umask might be mistakenly 0 while handling input signals.
3089 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3091 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3097 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3098 access to `contents' member of Lisp_Vector objects with AREF and ASET
3101 2012-06-19 Chong Yidong <cyd@gnu.org>
3103 * frame.c (delete_frame): When selecting a frame on a different
3104 text terminal, do not alter the terminal's top-frame.

3108 (unwind_format_mode_line): Restore them.
3109 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3111 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3112 since tty frames can be explicitly named.
3113 (prepare_menu_bars): Likewise.
3115 * term.c (Ftty_top_frame): New function.
3117 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

3120 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3121 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3122 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3123 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3124 (METER_1, METER_2): Simplify.
3126 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3128 * data.c (Fdefalias): Return `symbol' (bug#11686).
3130 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3132 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3133 gets killed during executing of this function (Bug#11665).
3134 Try to always return Qt when the buffer has been actually killed.
3135 (Vkill_buffer_query_functions): In doc-string say that functions
3136 run by this hook should not change the current buffer.
3138 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3140 Fix recently-introduced process.c problems found by static checking.
3141 * process.c (write_queue_push, write_queue_pop, send_process):

3158 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3160 * lisp.h (eassert): Assume C89 or later.
3161 This removes the need for CHECK.
3162 (CHECK): Remove. Its comments about always evaluating its
3163 argument were confusing, as 'eassert' typically does not evaluate
3166 * coding.c (produce_chars): Use ptrdiff_t, not int.
3168 * xterm.c (x_draw_underwave): Check for integer overflow.
3169 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3353 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3354 code works fine either way, and efficiency is not a concern here,
3355 as the union type is for debugging, not for production.
3356 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3357 Use an inline function on all platforms when using the union type,
3358 since this is simpler and 'static inline' can be used portably
3360 (LISP_INITIALLY_ZERO): New macro.
3361 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3362 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3500 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3502 * doprnt.c (doprnt): Truncate multibyte char correctly.
3503 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3504 would mishandle a string argument "Xc" if X was a multibyte
3505 character of length 2: it would truncate after X's first byte
3506 rather than including all of X.
3508 2012-06-06 Chong Yidong <cyd@gnu.org>
3510 * buffer.c (word_wrap): Doc fix.

3559 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3560 Convert pctcpu and pctmem to Lisp float properly.
3561 Let the compiler fold better, as 100.0/0x8000 is exact.
3563 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3565 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3568 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3570 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3572 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>

3575 bitfields where appropriate, remove unused fields.
3576 * window.h (struct window): Remove unused 'last_mark_x' and
3577 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

3580 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3581 fields from Lisp_Object to bitfield. Adjust users accordingly.

3587 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:

3589 and 'double' in a couple of places.
3591 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3593 * xdisp.c (handle_stop): Detect whether we have overlay strings
3594 loaded by testing it->current.overlay_string_index to be
3595 non-negative, instead of checking whether n_overlay_strings is
3596 positive. (Bug#11587)
3598 2012-05-31 Chong Yidong <cyd@gnu.org>
3600 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

3608 maybe_unify_char, which was the cause of relocation of buffer text
3611 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3613 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3614 for the duration of call to load_charset, to avoid problems with
3615 callers of maybe_unify_char that access buffer text through C
3618 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3619 decrement the inhibition flag, instead of just setting or
3622 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3624 Remove obsolete '#define static' cruft.
3625 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3626 This #undef was "temporary" in 2000; it is no longer needed
3627 now that '#define static' has gone away.
3628 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3629 (gray_bitmap_bits): Remove; no longer needed.
3630 All uses replaced with definiens.

3674 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3675 Bug#9642, but explicitly check that the buffer the overlay would
3676 be moved to is live and rearrange lines to make sure that errors
3677 will not put the overlay in an inconsistent state.
3678 (Fdelete_overlay): Cosmetics.
3680 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3682 * w32term.c (my_bring_window_to_top): New function.

3737 they are now on lisp.h.
3739 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3741 * search.c (search_buffer): Use it to inhibit relocation of buffer
3742 text while re_search_2 is doing its job, because re_search_2 is
3743 passed C pointers to buffer text. (Bug#11519)
3745 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3748 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3749 state after an additional call to move_it_in_display_line_to, keep
3750 the values of it->max_ascent and it->max_descent found for the

3753 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3756 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3758 Fix coding-related core dumps with gcc -ftrapv.
3759 The code was computing A - B, where A and B are pointers, and B is
3760 random garbage. This can lead to core dumps on platforms that
3761 have special pointer registers, and it also leads to core dumps on
3762 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3763 A - B only when B is initialized properly.
3764 * coding.c (coding_set_source, coding_set_destination): Return void.
3765 (coding_change_source, coding_change_destinations): New functions,

3784 * w32inevt.c: Include termchar.h and window.h.
3785 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3786 moves, call note_mouse_highlight. If help_echo changed, call
3787 gen_help_event to produce help-echo message in the echo area.
3788 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3791 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3793 * lread.c (read1): Simplify slightly to avoid an overflow warning
3794 with GCC 4.7.0 on x86-64.
3796 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3798 * bidi.c (bidi_mirror_char): Revert last change: an int is
3799 definitely wide enough here.
3801 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

3815 Use int, not EMACS_INT, where int is wide enough.
3816 (inhibit_garbage_collection, Fgarbage_collect):

3836 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3837 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3838 (validate_region): Omit unnecessary test for b <= e,
3839 since that's guaranteed by the previous test.
3840 (adjust_overlays_for_delete): Avoid pos + length overflow.
3841 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3842 (report_overlay_modification):
3843 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3844 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3853 not int, to avoid needless 32-bit limit on 64-bit hosts.
3854 (exec_byte_code): Use tighter memory-full test, one that checks
3855 for alloca overflow. Don't compute the address of the object just
3856 before an array, as that's not portable. Use EMACS_INT, not
3857 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3858 * callint.c (Fcall_interactively):
3859 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3871 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3872 (casify_object): Avoid integer overflow when overallocating buffer.
3873 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3875 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3876 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3877 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3880 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3881 For CCL_MapSingle, check that content and value are in int range.
3882 (ccl_driver, Fregister_code_conversion_map):
3883 Check that Vcode_version_map_vector is a vector.
3884 (resolve_symbol_ccl_program): Check that vector header is in range.
3885 Always copy the vector, so that we can check its contents reliably
3886 now rather than having to recheck each instruction as it's being
3887 executed. Check that vector words fit in 'int'.
3888 (ccl_get_compiled_code, Fregister_ccl_program)
3889 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3890 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3892 contents are in range.
3893 (Fccl_execute_on_string): Check that status is in range.
3894 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3895 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3896 Accept and return EMACS_INT, not int, because callers can pass values

3903 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3905 avoid mishandling large integers.

3916 Don't rely on undefined behavior with signed left shift overflow.
3917 Don't assume unsigned int fits into fixnum, or that fixnum fits
3918 into unsigned int. Don't require max_code to be a valid fixnum;
3919 that's not true for gb10830 4-byte on a 32-bit host. Allow
3920 invalid_code to be a cons, for the same reason. Require code_offset
3921 to be a character. Avoid int overflow if max_char is close
3923 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3924 this is intended anyway and avoids some undefined behavior.
3925 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3926 INDEX_TO_CODE_POINT, as that's what it expects.
3927 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3928 * charset.h (DECODE_CHAR): Return int, not unsigned;
3929 this is what was intended anyway, and it avoids undefined behavior.
3930 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3931 integer-overflow issues.
3932 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3933 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3934 where the argument is EMACS_INT, and this behavior is not intended.
3935 * chartab.c (Fmake_char_table, Fset_char_table_range)
3936 (uniprop_get_decoder, uniprop_get_encoder):
3937 Don't assume fixnum fits in int.
3938 * cmds.c (move_point): New function, that does the gist of
3939 Fforward_char and Fbackward_char, but does so while checking
3940 for integer overflow more accurately.
3941 (Fforward_char, Fbackward_char): Use it.
3942 (Fforward_line, Fend_of_line, internal_self_insert)
3943 (internal_self_insert):
3944 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4646 define them any more.

4655 Move here from removed file m/intel386.h.

4725 2012-05-14 Glenn Morris <rgm@gnu.org>
4727 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4728 Put "libexec" before "bin", for the sake of init_callproc_1.
4730 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4732 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

4735 (report_error, report_error_1, make_hdr, copy_sym)
4736 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4737 Make arguments const char *, not char *, to avoid violations of C
4738 standard and to fix some AIX warnings reported by Gilles Pion.
4740 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4742 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4743 already have overlays loaded.
4744 (handle_single_display_spec): Before returning without displaying
4745 fringe bitmap, synchronize the bidi iterator with the main display
4746 iterator, by calling iterate_out_of_display_property.
4747 (iterate_out_of_display_property): Detect buffer iteration by
4748 testing that it->string is a Lisp string.
4749 (get_next_display_element): When the current object is exhausted,
4750 and there's something on it->stack, call set_iterator_to_next to
4751 proceed with what's on the stack, instead of returning zero.
4752 (set_iterator_to_next): If called at the end of a Lisp string,
4753 proceed to consider_string_end without incrementing string
4754 position. Don't increment display vector index past the end of
4755 the display vector. (Bug#11417)
4756 (pos_visible_p): Don't report a position visible when move_it_to
4757 stopped at the last line of window, which happens to be scanned
4758 backwards by the bidi iteration. (Bug#11464)
4760 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4762 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4763 and right-margin display specs even if the spec is invalid or we
4764 are on a TTY, and thus unable to display on the fringes.
4765 That's because the text with the property will not be displayed anyway,
4766 so we need to signal to the caller that this is a "replacing"
4767 display spec. This fixes display when the spec is invalid or we
4770 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4772 * unexaix.c (make_hdr): Fix typo in prototype.
4773 This bug broke the build on AIX. Problem reported by Gilles Pion.
4775 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4777 * keyboard.c (kbd_buffer_get_event): Read special events also in
4778 batch mode. (Bug#11415)
4780 2012-05-12 Glenn Morris <rgm@gnu.org>

4788 2012-05-12 Glenn Morris <rgm@gnu.org>
4790 * Makefile.in (MKDIR_P): New, set by configure.
4791 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4793 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4795 Remove unused function hourglass_started.
4796 * dispextern.h (hourglass_started):

4803 Update dependencies.
4805 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4807 * xgselect.c (xg_select): Put maxfds+1 into a var.
4808 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4810 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4812 2012-05-10 Dave Abrahams <dave@boostpro.com>
4814 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4815 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4817 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4819 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4820 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4821 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4822 Initialize xd_registered_buses.
4824 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4826 Untag more efficiently if USE_LSB_TAG.
4827 This is based on a proposal by YAMAMOTO Mitsuharu in
4828 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4829 For an admittedly artificial (nth 8000 longlist) benchmark on
4830 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4831 Emacs's overall text size by 1%.
4832 * lisp.h (XUNTAG): New macro.
4833 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4834 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4835 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4836 * eval.c (Fautoload):
4837 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4838 * frame.h (XFRAME): Use XUNTAG.
4840 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4841 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4842 Remove unportable assumptions about print widths of types like
4844 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4845 intptr_t when converting between pointer and integer, to avoid GCC
4846 warnings about wrong width.
4848 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4850 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4851 stack for each reader_thread, instead of defaulting to 8MB
4852 determined by the linker. This avoids failures in creating
4853 subprocesses on Windows 7, see the discussion in this thread:

4858 Fix up display of the *Minibuf-0* buffer in the mini window.
4859 * keyboard.c (read_char): Don't clear the echo area if there's no
4861 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4862 contents of *Minibuf-0*) if there's no message displayed in its stead.
4864 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4866 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4869 2012-05-06 Chong Yidong <cyd@gnu.org>
4871 * lisp.mk (lisp): Update.
4873 2012-05-05 Jim Meyering <meyering@redhat.com>
4875 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4877 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4879 * data.c (PUT_ERROR): New macro.
4880 (syms_of_data): Use it. Add new error type `user-error'.
4881 * undo.c (user_error): New function.
4882 (Fprimitive_undo): Use it.
4883 * print.c (print_error_message): Adjust print style for `user-error'.
4884 * keyboard.c (user_error): New function.
4885 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4887 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4889 Do not limit current-time-string to years 1000..9999.
4890 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4891 (Fcurrent_time_string): Support any year that is supported by the
4892 underlying localtime representation. Don't use asctime, as it
4893 has undefined behavior for years outside the range -999..9999.
4895 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4897 Fix race conditions involving setenv, gmtime, localtime, asctime.
4898 Without this fix, interrupts could mess up code that uses these
4899 nonreentrant functions, since setting TZ invalidates existing
4900 tm_zone or tzname values, and since most of these functions return
4901 pointers to static storage.
4902 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4903 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4904 Grow the critical sections to include not just invoking
4905 localtime/gmtime, but also accessing these functions' results
4906 including their tm_zone values if any, and any related TZ setting.
4907 (format_time_string): Last arg is now struct tm *, not struct tm **,
4908 so that the struct tm is saved in the critical section.
4909 All callers changed. Simplify allocation of initial buffer, partly
4910 motivated by the fact that memory allocation needs to be outside
4911 the critical section.
4913 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4915 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4916 with RESET_INTERVAL.
4918 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4919 Remove duplicated buffer name initialization.
4921 2012-05-02 Jim Meyering <jim@meyering.net>
4923 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4925 * xfns.c (x_window): Use xstrdup (Bug#11375).
4927 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4929 * xdisp.c (pos_visible_p): If already at a newline from the
4930 display string before the 'while' loop, don't walk back the glyphs
4931 from it3.glyph_row. Solves assertion violation when the display
4932 string begins with a newline (egg.el). (Bug#11367)
4934 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4936 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4939 2012-05-01 Glenn Morris <rgm@gnu.org>
4941 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4942 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4943 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4944 All were removed before 23.1.
4946 * dispnew.c: Remove HAVE_LIBNCURSES test;
4947 it is always true on relevant platforms.
4949 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4950 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4952 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4954 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4956 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4957 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4960 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4962 Do not avoid creating empty evaporating overlays (Bug#9642).
4963 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4964 That is, do not delete an evaporating overlay if it becomes
4965 empty after its bounds are adjusted to fit within its buffer.
4966 This fix caused other problems, and I'm reverting it until we get
4967 to the bottom of them.
4969 2012-04-27 Chong Yidong <cyd@gnu.org>
4971 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4973 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4975 * xdisp.c (pos_visible_p): If the window start position is beyond
4976 ZV, start the display from buffer beginning. Prevents assertion
4977 violation in init_iterator when the minibuffer window is scrolled
4980 * window.c (window_scroll_pixel_based): Likewise.
4982 2012-04-27 Chong Yidong <cyd@gnu.org>
4984 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4986 2012-04-27 Glenn Morris <rgm@gnu.org>
4988 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4989 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4991 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4993 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4994 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4996 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4998 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4999 display element, check also the underlying string or buffer
5000 character. (Bug#11341)
5002 * w32menu.c: Include w32heap.h.
5003 (add_menu_item): If the call to AppendMenuW (via
5004 unicode_append_menu) fails, disable Unicode menus only if we are
5005 running on Windows 9X/Me.
5007 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5009 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5010 (xgetint): Add missing shift for LSB tags.
5012 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5014 * keyboard.c (read_char): Don't wipe echo area for select window
5015 events: These might get delayed via `mouse-autoselect-window'
5018 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5020 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5021 manipulation of :loaded-from data.
5023 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5025 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5026 now a cons (bug#11311).
5028 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5030 Do not create empty overlays with the evaporate property (Bug#9642).
5031 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5032 if it becomes empty after its bounds are adjusted to fit within
5033 its buffer. Without this fix, in a nonempty buffer (let ((o
5034 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5035 yields an empty overlay that has the evaporate property, which is
5036 not supposed to happen.
5038 Fix minor GTK3 problems found by static checking.
5039 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5040 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5041 (struct _EmacsFixedClass, emacs_fixed_get_type):

5049 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5050 (EMACS_FIXED_GET_CLASS): Remove; unused.
5051 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5053 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5054 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5056 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5058 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5059 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5060 (__malloc_size_t, __malloc_ptrdiff_t):
5061 Remove. All uses removed, replaced by the definiens if needed,
5062 since we can assume C89 or better now.
5063 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

5073 Define using prototypes, not old style.
5074 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

5255 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5256 [REL_ALLOC]: ... to here, to check interface.
5257 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5258 Remove decls. This fixes an "It stinks!".
5260 * alloc.c (which_symbols): Fix alignment issue / type clash.

5282 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5283 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5284 no longer the default.
5285 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.

5310 2012-04-11 Daniel Colascione <dancol@dancol.org>
5312 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5313 against is gone. It's better to use vfork now so that when Cygwin
5314 gains a new, working vfork, we use it automatically (bug#10398).
5316 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5318 * window.c (save_window_save): Obey window-point-insertion-type.

5328 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5330 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5331 (force_quit_count): New var.
5332 (handle_interrupt): Use it.
5334 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5336 * w32.c (w32_delayed_load): Record the full path of the library
5337 being loaded (bug#10424).
5339 2012-04-09 Glenn Morris <rgm@gnu.org>
5341 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5342 not just in the obarray, before snarfing them. (Bug#11036)
5344 * Makefile.in ($(leimdir)/leim-list.el):
5345 Pass EMACS rather than BUILT_EMACS.
5347 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5349 * process.c (make_process):
5350 * process.h: Add integer `gnutls_handshakes_tried' member to
5353 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5354 Add convenience `GNUTLS_LOG2i' macro.
5356 * gnutls.c (gnutls_log_function2i): Convenience log function.
5357 (emacs_gnutls_read): Use new log functions,
5358 `gnutls_handshakes_tried' process member, and
5359 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5360 attempts per process (connection).
5362 2012-04-09 Chong Yidong <cyd@gnu.org>
5364 * eval.c (Fuser_variable_p, user_variable_p_eh)

5366 (Fdefvar): Caller changed.
5368 * callint.c (Finteractive, Fcall_interactively):
5369 * minibuf.c (Fread_variable): Callers changed.
5371 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5373 * xdisp.c (set_cursor_from_row): If the display string appears in
5374 the buffer at position that is closer to point than the position
5375 after the display string, display the cursor on the first glyph of
5376 the display string. Fixes cursor display when a 'display' text
5377 property immediately follows invisible text. (Bug#11094)
5379 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5381 composite.c: use 'double' consistently
5382 * composite.c (get_composition_id): Use 'double' consistently
5383 instead of converting 'float' to 'double' and vice versa; this is
5384 easier to understand and avoids a GCC warning.
5386 2012-04-09 Glenn Morris <rgm@gnu.org>
5388 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5389 preparation for dumping it with emacs. (Bug#4789)
5390 (leimdir): New variable.
5391 ($(leimdir)/leim-list.el): New rule.
5392 (emacs$(EXEEXT)): Depend on leim-list.el.

5395 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
5396 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
5398 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5400 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5403 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5405 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5406 Remove unused local variable.
5408 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5410 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5411 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5412 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5413 objects, as mark_maybe_pointer will catch them otherwise.
5414 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5415 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5417 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5419 Fix typo that broke non-Windows builds.
5420 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5422 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5424 Support building on MS-Windows with libxml2.
5426 * makefile.w32-in (OBJ2): Add xml.$(O).
5427 (GLOBAL_SOURCES): Add xml.c.
5428 ($(BLD)/xml.$(O)): New dependency list.
5430 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5431 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5432 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5433 [!WINDOWSNT]: New macros.
5434 (init_libxml2_functions, libxml2_loaded_p): New functions.
5435 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5436 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5437 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5438 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5440 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5441 Call init_libxml2_functions before calling libxml2 functions.
5442 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5444 * emacs.c: Don't include libxml/parser.h.
5445 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5446 xmlCleanupParser directly.
5448 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5450 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5452 * indent.c (Fvertical_motion): If there is a display string at
5453 point, use it.vpos to compute how many lines to backtrack after
5454 move_it_to point. (Bug#11133)
5456 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5458 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5459 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5460 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5461 macros related to unification of CJK characters. For the details,
5462 see the discussion following the message here:
5463 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5465 2012-04-04 Chong Yidong <cyd@gnu.org>
5467 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5469 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5471 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5472 instead of alloca. (Bug#11138)
5474 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5476 * w32menu.c (is_simple_dialog): Properly check lisp types.
5479 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5481 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5482 position we get to after a call to move_it_to fails the
5483 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5484 only if we wind up in a string from display property. (Bug#11063)
5486 * window.c (Fdelete_other_windows_internal): Invalidate the row
5487 and column information about mouse highlight, so that redisplay
5488 restores it after reallocating the glyph matrices. (Bug#7464)
5490 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5491 string comes from a `display' text property, use the buffer
5492 position of that property as if we actually saw that position in
5494 (move_it_by_lines): Remove the assertion that
5495 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5496 violated when there's a before-string at the beginning of a line.
5499 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5501 * xdisp.c (append_space_for_newline): If the default face was
5502 remapped, use the remapped face for the appended newline.
5503 (extend_face_to_end_of_line): Use the remapped default face for
5504 extending the face to the end of the line.
5505 (display_line): Call extend_face_to_end_of_line when the default
5506 face was remapped. (Bug#11068)
5508 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5510 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5512 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5514 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5516 2012-03-27 Glenn Morris <rgm@gnu.org>
5518 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5521 2012-03-26 Kenichi Handa <handa@m17n.org>
5523 * dispextern.h (struct glyph): Fix previous change. Change the
5524 bit length of glyphless.ch to 25 (Bug#11082).
5526 2012-03-26 Chong Yidong <cyd@gnu.org>
5528 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5529 (command_loop_1): Use it; inhibit selection update for
5530 handle-select-window too (Bug#8996).
5532 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5534 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5536 2012-03-25 Kenichi Handa <handa@m17n.org>
5538 * dispextern.h (struct glyph): Change the bit length of
5539 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5541 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5543 * s/ms-w32.h (tzname): Include time.h before redirecting to
5544 _tzname. Fixes the MSVC build. (Bug#9960)
5546 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5548 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5551 * xterm.c (XTread_socket): Only modify handling_signal if
5552 !SYNC_INPUT. (Bug#11080)
5554 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5556 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5557 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5558 when fetching a multibyte character consumes more bytes than
5559 CHAR_BYTES returns, due to unification of CJK characters in
5560 string_char. (Bug#11073)
5562 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5564 * process.c (wait_reading_process_output): Handle pty disconnect
5565 by refraining from sending oneself a SIGCHLD (bug#10933).
5567 2012-03-22 Chong Yidong <cyd@gnu.org>
5569 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5571 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5572 Mark string as coming from a prefix property.
5573 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5574 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5576 2012-03-21 Chong Yidong <cyd@gnu.org>
5578 * xfaces.c (Vface_remapping_alist): Doc fix.
5580 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5582 * w32proc.c (Fw32_set_console_codepage)
5583 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5586 2012-03-20 Chong Yidong <cyd@gnu.org>
5588 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5589 to reflect default non-nil value of redisplay-dont-pause.
5591 2012-03-19 Kenichi Handa <handa@m17n.org>
5593 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5594 it fit in a valid range (Bug#11003).
5596 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5598 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5599 that is not from display property, accept the row as a "cursor
5600 row" if one of the string's character has a non-nil `cursor'
5601 property. Fixes cursor positioning when there are newlines in
5602 overlay strings, e.g. in icomplete.el. (Bug#11035)
5604 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5606 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5608 2012-03-12 Chong Yidong <cyd@gnu.org>
5610 * eval.c (inhibit_lisp_code): Rename from
5611 inhibit_window_configuration_change_hook; move from window.c.
5613 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5614 * window.c (run_window_configuration_change_hook)
5615 (syms_of_window): Callers changed.
5617 2012-03-11 Chong Yidong <cyd@gnu.org>
5619 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5621 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5623 2012-03-10 Chong Yidong <cyd@gnu.org>
5625 * frame.c (other_visible_frames): Don't assume the selected frame
5626 is visible (Bug#10955).
5628 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5630 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5632 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5634 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5635 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5638 2012-03-03 Glenn Morris <rgm@gnu.org>
5640 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5642 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5644 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5645 position past the first glyph_row that ends at ZV. (Bug#10902)
5646 (redisplay_window, next_element_from_string): Fix typos in
5648 (redisplay_window): Pass to move_it_vertically the margin in
5649 pixels, not in screen lines.
5651 2012-03-02 Glenn Morris <rgm@gnu.org>
5653 * buffer.c (buffer-list-update-hook): Doc fix.
5655 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5657 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5658 push_it before setting up the iterator for the first overlay
5659 string, even if we have an empty string loaded.
5660 (next_overlay_string): If there's an empty string on the iterator
5661 stack, pop the stack. (Bug#10903)
5663 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5665 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5666 Suggested by Stefan Monnier in
5667 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5668 * alloc.c (widen_to_Lisp_Object): New static function.
5669 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5670 and widening them to Lisp_Objects. This would work even if
5671 USE_LSB_TAG is defined and wide integers are used, which might
5672 happen in a future version of Emacs.
5674 2012-02-25 Chong Yidong <cyd@gnu.org>
5676 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5679 * xselect.c (Fx_selection_exists_p): Doc fix.
5680 (x_clipboard_manager_save_all): Print an informative message
5681 before saving to clipboard manager.
5683 2012-02-24 Chong Yidong <cyd@gnu.org>
5685 * keyboard.c (process_special_events): Handle all X selection
5686 requests in kbd_buffer, not just the next one (Bug#8869).
5688 2012-02-23 Chong Yidong <cyd@gnu.org>
5690 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5691 call when setting menu-bar-lines and tool-bar-lines parameters.
5692 (unwind_create_frame_1): New helper function.
5694 * window.c (inhibit_window_configuration_change_hook): New var.
5695 (run_window_configuration_change_hook): Obey it.
5696 (syms_of_window): Initialize it.
5698 2012-02-22 Chong Yidong <cyd@gnu.org>
5700 * xterm.c (x_draw_image_relief): Add missing type check for
5701 Vtool_bar_button_margin (Bug#10743).
5703 2012-02-21 Chong Yidong <cyd@gnu.org>
5705 * fileio.c (Vfile_name_handler_alist): Doc fix.
5707 * buffer.c (Fget_file_buffer): Protect against invalid file
5708 handler return value.
5710 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5712 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5713 when computing $valmask.
5715 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5716 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5717 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5718 It's useless in that case, and it can cause problems on hosts
5719 that allocate halves of EMACS_INT values separately.
5720 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5721 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5722 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5723 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5724 it avoids undefined behavior on hosts where shifting right by more
5725 than the word width has undefined behavior.
5727 2012-02-19 Chong Yidong <cyd@gnu.org>
5729 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5730 (Funhandled_file_name_directory, Ffile_name_as_directory)
5731 (Fdirectory_file_name, Fexpand_file_name)
5732 (Fsubstitute_in_file_name): Protect against invalid file handler
5733 return values (Bug#10845).
5735 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5737 * .gdbinit (pitx): Fix incorrect references to fields of the
5740 2012-02-17 Chong Yidong <cyd@gnu.org>
5742 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5744 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5746 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5747 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5749 2012-02-15 Chong Yidong <cyd@gnu.org>
5751 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5752 marked as special. Also, starting docstrings with * is obsolete.
5754 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5756 * gnutls.c (emacs_gnutls_write): Fix last change.
5758 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

5763 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5765 * keymap.c (Fsingle_key_description): Handle char ranges.
5767 2012-02-12 Chong Yidong <cyd@gnu.org>
5769 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5770 as that creates a dangerous corner case.
5772 * window.c (Fdelete_window_internal): Invalidate the mouse
5773 highlight (Bug#9904).
5775 2012-02-12 Glenn Morris <rgm@gnu.org>
5777 * xselect.c (Fx_own_selection_internal)
5778 (Fx_get_selection_internal, Fx_disown_selection_internal)
5779 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5780 * nsselect.m (Fx_own_selection_internal)
5781 (Fx_disown_selection_internal, Fx_selection_exists_p)
5782 (Fx_selection_owner_p, Fx_get_selection_internal):
5783 Sync docs and argument specs with the xselect.c versions.
5785 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5787 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5789 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5791 * w32select.c (Fx_selection_exists_p): Sync doc string and
5792 argument list with xselect.c. (Bug#10783)
5794 * w16select.c (Fx_selection_exists_p): Sync doc string and
5795 argument list with xselect.c. (Bug#10783)
5797 2012-02-10 Glenn Morris <rgm@gnu.org>

6324 (Fword_search_backward_lax, Fword_search_forward_lax):
6325 Use `Fword_search_regexp' instead of `wordify'. Doc fix.
6326 (syms_of_search): Define `Sword_search_regexp'. (Bug#10145)
6328 2011-12-01 Stefan Monnier <monnier@iro.umontreal.ca>
6330 * fileio.c (Finsert_file_contents): Move after-change-function call
6331 to before the "handled:" label, since all "goto handled" appear in
6332 cases where the *-change-functions have already been properly called

6377 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
6378 of scroll runs so as to avoid assigning disabled bogus rows and
6379 unnecessary graphics copy operations.
6381 2011-11-27 Eli Zaretskii <eliz@gnu.org>
6383 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

6390 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6391 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
6392 this macro definition.
6394 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
6397 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

6419 * xdisp.c (redisplay_window): If cursor row is not fully visible
6420 after recentering, and scroll-conservatively is set to a large
6421 number, scroll window by a few more lines to make the cursor fully
6422 visible and out of scroll-margin. (Bug#10105)
6423 (start_display): Don't move to the next line if the display should
6424 start at a newline that is part of a display vector or an overlay

6505 Otherwise, valgrind does not work on some platforms.
6506 Problem reported by Andreas Schwab in
6507 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6508 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6509 is set, removing the need for VIRT_ADDRESS_VARIES.
6510 (PURE_P): Use a more-efficient implementation that needs just one
6511 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6512 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6513 to 4 (xorl, subq, cmpq, setbe).
6514 * alloc.c (pure): Always extern now, since that's the
6515 VIRT_ADDR_VARIES behavior.
6516 (PURE_POINTER_P): Use a single comparison, not two, for
6517 consistency with the new puresize.h.
6518 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6519 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6525 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6526 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6527 behave as if the cursor position were at the window margin.
6529 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6530 and the cursor position is out of bounds, behave as if the cursor
6531 position were at the window margin. (Bug#10075)
6533 2011-11-18 Chong Yidong <cyd@gnu.org>
6535 * window.c (Fwindow_combination_limit): Make first argument
6536 non-optional, since it is meaningless for live windows like the

6554 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
6556 * xdisp.c (row_hash): New function, body extracted from
6557 compute_line_metrics.
6558 (compute_line_metrics): Call row_hash, instead of computing the
6561 * dispnew.c (verify_row_hash): Call row_hash for computing the
6562 hash code of a row, instead of duplicating code from xdisp.c.
6564 * dispextern.h (row_hash): Add prototype.
6566 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6568 * frame.c (delete_frame): Don't delete the terminal when the last
6569 X frame is closed if emacs is built with GTK toolkit.

6591 (Fset_window_nest): Rename to Fset_window_combination_limit.
6592 (Vwindow_nest): Rename to Vwindow_combination_limit.
6593 (recombine_windows, make_parent_window, make_window)
6594 (Fsplit_window_internal, saved_window)
6595 (Fset_window_configuration, save_window_save): Rename all
6596 occurrences of window_nest to window_combination_limit.
6598 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6600 * image.c (imagemagick_load_image): Fix typo.
6602 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6604 * xdisp.c (display_line): Move the call to
6605 highlight_trailing_whitespace before the call to
6606 compute_line_metrics, since the latter needs to see the final
6607 faces of all the glyphs to compute ROW's hash value.
6608 Fixes assertion violations in row_equal_p. (Bug#10035)
6610 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6612 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6617 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6618 with user-defined heap size. Bump the default size of the temacs
6619 heap to 27MB, to avoid memory warning when running temacs.
6620 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6622 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6669 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6671 Avoid some portability problems by eschewing 'extern inline' functions.
6672 The trivial performance wins aren't worth the portability hassles; see
6673 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6675 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6676 (window_box_width, window_box_left, window_box_left_offset)
6677 (window_box_right, window_box_right_offset): Undo previous change,
6678 by removing the "extern"s.
6679 * intervals.c (adjust_intervals_for_insertion)
6680 (adjust_intervals_for_deletion): Undo previous change,
6681 making these static again.
6682 (offset_intervals, temp_set_point_both, temp_set_point)
6683 (copy_intervals_to_string): No longer inline.
6684 * xdisp.c (window_text_bottom_y, window_box_width)

6721 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
6723 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6724 This is also needed for porting to any host where GC_MARK_STACK is
6725 not GC_MAKE_GCPROS_NOOPS.
6726 (which_symbols): Use it.
6728 2011-11-07 Kenichi Handa <handa@m17n.org>

6741 * xmenu.c (cleanup_widget_value_tree): New function.
6742 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6749 (window_box_width, window_box_left, window_box_left_offset)
6750 (window_box_right, window_box_right_offset): Declare extern.
6751 Otherwise, these inline functions do not conform to C99 and
6752 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6753 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6754 * intervals.c (adjust_intervals_for_insertion)
6755 (adjust_intervals_for_deletion): Now extern, because otherwise the
6756 extern inline functions 'offset_intervals' couldn't refer to it.
6757 (static_offset_intervals): Remove.
6758 (offset_intervals): Rewrite using the old contents of
6759 static_offset_intervals. The old version didn't conform to C99
6760 because an extern inline function contained a reference to an
6761 identifier with static linkage.
6763 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6765 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6783 (Fwindow_vscroll): Doc fix.
6784 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6785 argument, since it makes no sense to pass a live window and for
6786 consistency with window-child.

6998 instead of calling the "wide" APIs directly.
7000 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

7050 * keyboard.c (test_undefined): New function (bug#9751).
7051 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7053 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7055 * sysdep.c (init_sys_modes): Fix the check for the controlling
7056 terminal (Bug#6649).
7058 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7060 * dispextern.h (struct bidi_it): New member next_en_type.
7062 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7063 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7064 current character, check also for next_en_type being WEAK_EN.
7065 (bidi_resolve_weak): Don't enter the expensive loop if the current
7066 position is before next_en_pos. Record the bidi type of the first
7067 non-ET, non-BN character we find, in addition to its position.
7068 (bidi_level_of_next_char): Invalidate next_en_type when
7069 next_en_pos is over-stepped.
7071 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7073 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7074 * editfns.c: Rewrite current-time-zone so that it invokes
7075 the equivalent of (format-time-string "%Z") to get the time zone name.
7076 This fixes a bug when the time zone name contains characters that
7077 need converting from the system time locale to Emacs internal format.
7078 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7079 that patch fixed format-time-string to do the conversion, but
7080 I forgot to fix current-time-zone.
7081 (format_time_string): New function, containing most of
7082 what Fformat_time_string used to contain.
7083 (Fformat_time_string): Rewrite in terms of format_time_string.
7084 This doesn't change this function's behavior.
7085 (current-time-zone): Rewrite to use format_time_string.
7086 This fixes the bug reported by Michael Schierl in
7087 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7088 Jason Rumney's 2007-06-07 change worked around this bug, but
7090 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7092 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7094 * xdisp.c (start_display): If the character at POS is displayed
7095 via a display vector, reset IT->current.dpvec_index to zero.
7096 (try_window_reusing_current_matrix): If a line ends in a display
7097 vector or the next line starts in a display vector, continue
7098 redrawing the window even though the character position of
7099 start_row was reached.
7102 2011-10-18 Chong Yidong <cyd@gnu.org>
7104 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7105 with nobreak-char-display too.
7107 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7109 Fix part 3 of bug#9771.
7110 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7111 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7112 non-neutral characters if the current character is a paragraph
7113 separator (a.k.a. Newline). This avoids running the same
7114 expensive loop twice, once when we consume the preceding newline
7115 and the other time when the line actually needs to be displayed.
7116 Avoid the loop when we see neutrals on the base embedding level
7117 following a character whose directionality is the same as the
7118 paragraph's. This avoids running the expensive loop when a line
7119 ends in a long sequence of neutrals, like control characters.
7120 Add assertion against STRONG_AL type. Slightly rearrange code
7121 that determines the type of a neutral given the first non-neutral
7123 (bidi_level_of_next_char): Set next_en_pos to zero when
7124 invalidating its info.
7126 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7128 * xdisp.c (push_display_prop): Determine whether to record string
7129 or buffer position by IT->string, not by IT->method. Allow
7130 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7131 (move_it_vertically_backward): Don't look for character position
7132 immediately after the newline when in a continuation line.
7135 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7137 * window.c (coordinates_in_window): Rewrite and delabelize
7138 vertical border check. (Bug#5357) (Bug#9618)
7140 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7142 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7143 errors in XSetWindowBorder (bug#9310).
7145 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7147 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7148 avoid crash when xmalloc overrun checking is enabled.
7150 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7152 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7153 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7154 cursor motion with <left> and <right> arrow keys.
7156 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7157 some callers set that themselves.
7159 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7161 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7162 display string and the previous row comes from the same string and
7163 is empty. (Bug#9739) (Bug#9738)
7165 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7167 * doc.c (get_doc_string): Encode file name (bug#9735).
7169 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7171 * bidi.c (bidi_level_of_next_char):
7172 * xdisp.c (get_visually_first_element): Remove old incorrect
7173 comments regarding the Unicode Line Separator character.
7175 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7177 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7179 * alloc.c (Fgc_status): Do not access beyond zombies array
7180 boundary if nzombies > MAX_ZOMBIES.
7181 * alloc.c (dump_zombies): Add missing format specifier.
7183 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7185 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7186 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7188 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7189 Some packages use them to denote characters with modifiers.
7191 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7193 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7194 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7195 matching a pp-number. Rename parameter var to var1.
7197 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7199 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7201 2011-10-08 Glenn Morris <rgm@gnu.org>
7203 * callint.c (Fcall_interactively): Give a more explicit error for the
7204 'c' case with a non-character input. (Bug#8479)
7206 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7208 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7210 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7211 lines that are hscrolled on the left.
7213 * dispnew.c (buffer_posn_from_coords): Account for a possible
7214 presence of header-line. (Bug#4426)
7216 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>

7219 Don't advertise functionality which we discourage or doesn't work.
7221 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7223 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7224 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7225 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7226 this makes Emacs dump core during garbage collection on rare
7227 occasions. sizeof is obviously inferior to offsetof here, so
7228 stick with offsetof.
7229 (GC_POINTER_ALIGNMENT): New macro.
7230 (mark_memory): Omit 3rd (offset) arg; caller changed.
7231 Don't assume EMACS_INT alignment is the same as pointer alignment.
7233 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7235 * keyboard.c (read_key_sequence_remapped): New var.
7236 (read_key_sequence): Compute remapping in the right buffer.
7237 (command_loop_1): Use read_key_sequence's remapping directly.
7239 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7241 * dired.c (file_name_completion): Don't expand file name.
7242 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7243 before checking file name handler.
7245 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7246 they've been requested explicitly (bug#9591).
7248 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7250 * keymap.c (Fsingle_key_description): Use make_specified_string
7251 instead of build_string to build string from push_key_description.
7254 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7256 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7257 This fixes a Y2038 bug on 64-bit hosts.
7258 * buffer.c (reset_buffer):
7259 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7260 (Fclear_buffer_auto_save_failure):
7261 Use 0, not -1, to represent an unset failure time, since time_t
7262 might not be signed.
7264 Remove dependency on glibc malloc internals.
7265 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7266 Move back here from lisp.h, but with their new implementations.
7267 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7268 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7269 * charset.c (charset_table_init): New static var.
7270 (syms_of_charset): Use it instead of xmalloc. This removes a
7271 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7272 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7273 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7274 Move back to alloc.c.
7275 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7276 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7278 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7280 * nsterm.m (windowDidResize): Call x_set_window_size only when
7281 ns_in_resize is true. Otherwise set pixelwidth/height and
7282 call change_frame_size (Bug#9628).
7284 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7286 Port --enable-checking=all to Fedora 14 x86-64.
7287 * charset.c (syms_of_charset): Also account for glibc malloc's
7288 internal overhead when calculating the initial malloc maximum.
7290 Port --enable-checking=all to Fedora 14 x86.
7291 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7293 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7294 (overrun_check_realloc, overrun_check_free):
7295 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7296 That way, xmalloc returns a properly-aligned pointer even if
7297 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7298 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7299 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7300 into account when calculating the initial malloc maximum.
7301 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7302 Move here from alloc.c, so that charset.c can use it too.
7303 Properly align; the old code wasn't right for common 32-bit hosts
7304 when configured with --enable-checking=all.
7305 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7306 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7308 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7310 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7313 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7315 * xdisp.c (compute_display_string_end): If there's no display
7316 string at CHARPOS, return -1.
7318 * bidi.c (bidi_fetch_char): When compute_display_string_end
7319 returns a negative value, treat the character as a normal
7320 character not covered by a display string. (Bug#9624)
7322 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7324 * lread.c (Fread_from_string): Fix typo in docstring.
7326 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7328 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7329 newline, reseat the iterator instead of bidi-iterating there one
7330 character at a time. (Bug#9610)
7331 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7332 TO_CHARPOS if the bidi iterator is at base embedding level.
7334 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7336 * lread.c (readevalloop): Use correct code for NBSP.
7337 (read1): Likewise. (Bug#9608)
7339 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7341 * dbusbind.c (Fdbus_register_signal): When service is not
7342 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7344 2011-09-25 Glenn Morris <rgm@gnu.org>
7346 * buffer.c (truncate-lines): Doc fix.
7348 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7350 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7351 (Fset_window_next_buffers): Doc fix.
7353 2011-09-24 Glenn Morris <rgm@gnu.org>
7355 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7357 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7359 Fix minor problems found by static checking.
7360 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7361 * indent.c (Fvertical_motion): Fix == vs = typo.
7363 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7365 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7366 Default value is now t. Doc fix.
7368 * indent.c (Fvertical_motion): Compute and apply the overshoot
7369 logic when moving up, not only when moving down. Fix the
7370 confusing name and values of the it_overshoot_expected variable;
7371 logic changes accordingly. (Bug#9254) (Bug#9549)
7373 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7374 CHARPOS is covered by a display string which includes newlines.
7375 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7376 is covered by a display string with embedded newlines.
7378 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7380 * dbusbind.c (Fdbus_register_signal): Add match rule to
7381 Vdbus_registered_objects_table. (Bug#9581)
7382 (Fdbus_register_method, Vdbus_registered_objects_table):
7385 2011-09-24 Jim Meyering <meyering@redhat.com>
7387 do not ignore write error for any output size
7388 The previous change was incomplete.
7389 While it makes emacs --batch detect the vast majority of stdout
7390 write failures, errors were still ignored whenever the output size is
7391 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7392 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7393 && echo FAIL: ignored write error
7394 FAIL: ignored write error
7395 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7396 && echo FAIL: ignored write error
7397 FAIL: ignored write error
7398 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7400 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7402 * emacs.c (Fkill_emacs): In noninteractive mode exit
7403 non-successfully if a write error occurred on stdout. (Bug#9574)
7405 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7407 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7410 * dispextern.h (struct it): Update the comment documenting what
7413 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7415 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7416 a display string, extend search for cursor position to end of row.
7417 (find_row_edges): If the row ends in a newline from a display
7418 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7419 Handle the case of a display string with multiple newlines.
7420 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7421 non-empty line. Fixes confusing cursor motion with arrow keys at
7422 the beginning of a line that starts with whitespace.
7424 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7426 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7429 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7431 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7434 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7436 * xdisp.c (display_line): Record maximum and minimum buffer
7437 positions even if no glyphs were produced (e.g., by a zero-width
7438 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7439 buffer positions that will be removed from the glyph row because
7441 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7442 column is beyond frame width: don't subtract 1 "pixel" when
7443 computing width of the stretch.
7444 (reseat_at_next_visible_line_start): Undo the change made on
7445 2011-09-17 that saved paragraph information and restored it after
7446 the call to `reseat'. (Bug#9545)
7448 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7450 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7451 and turn window cursor on if cleared (Bug#9415).
7453 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7455 * search.c (boyer_moore): Take unibyte characters from pattern
7456 literally. (Bug#9458)
7458 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7460 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7462 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7464 Fix minor problem found by static checking.
7465 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7466 initialized, to pacify gcc -Wuninitialized.
7468 * fileio.c: Report proper errno when syscall falls.
7469 (Finsert_file_contents): Save and restore errno,
7470 so that report_file_error outputs the correct diagnostic.
7471 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7473 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7475 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7477 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7479 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7480 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7482 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7484 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7485 about the current paragraph and restore it after the call to reseat.
7487 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7488 (bidi_find_paragraph_start): Search back for paragraph beginning
7489 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7490 (bidi_move_to_visually_next): Only trigger paragraph-related
7491 computations when the last character is a newline or at EOB, not
7492 just any NEUTRAL_B. (Bug#9470)
7494 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7495 truncated lines if point is covered by a display string. (Bug#9524)
7497 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7499 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7500 (cons_to_x_long): New function.
7501 (lisp_data_to_selection_data): Use it. Correct the test for
7502 short-versus-long data; it was negated. Break out of vector
7503 loop, for efficiency, when a long datum is discovered.
7505 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7507 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7509 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7511 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7512 GCC PR/17406) by declaring this function with external scope.
7514 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7516 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7517 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7519 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7521 * editfns.c (Fformat): Correctly handle text properties on "%%".

7528 * composite.c (composition_update_it, get_composition_id):
7529 * xdisp.c (get_next_display_element)

7531 of TAB characters in a composition.
7533 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7535 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7536 This occurs when processing a multibyte format.
7537 Problem reported by Wolfgang Jenker.
7539 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7541 * xdisp.c (try_cursor_movement): Only check for exact match if
7542 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7544 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7546 Remove unused external symbols.
7547 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7548 * xdisp.c (calc_pixel_width_or_height): Now static.
7549 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7550 * indent.c (check_display_width):
7551 * w32term.c: Fix comment to match code.
7552 * xterm.c, xterm.h (x_catching_errors): Remove.
7554 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7556 * xselect.c: Use signed conversions more consistently (Bug#9498).
7557 (selection_data_to_lisp_data): Assume incoming selection data are
7558 signed integers, not unsigned. This is to be consistent with
7559 outgoing selection data, which was modified to use signed integers
7560 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7561 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7562 expects long, not unsigned long.
7564 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7566 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7567 computation of loop end. Reported by Johan Bockgård
7570 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7572 * frame.c (Fother_visible_frames_p): Function deleted.
7574 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7576 * indent.c (compute_motion): Process display vector front to back
7577 rather than the other way around. (Bug#2496)
7579 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7581 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7583 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7585 * minibuf.c (Fread_from_minibuffer): Doc fix.
7587 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7589 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7590 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7592 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7594 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7595 value for non-existent files.
7597 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7599 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7600 set its "size" to -1. This will set the modtime_size field of
7601 the corresponding buffer to -1, which is what
7602 verify-visited-file-modtime expects for files that do not exist.
7605 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7607 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7609 * lisp.h: ... from here. push_key_description is no longer
7610 defined in keyboard.c, so its declaration should not be in
7611 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7612 logically belongs with push_key_description.
7614 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7616 * buffer.h: Include <sys/types.h> instead of <time.h>.
7617 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7618 Problem reported by Herbert J. Skuhra.
7620 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7622 * xml.c (parse_region): Make the parsing work for
7623 non-comment-starting XML files again (bug#9144).
7625 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7627 * image.c (gif_load): Fix calculation of bottom and right corner.
7630 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7632 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7633 redisplay in small windows.
7635 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7637 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7639 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7641 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7642 Operate on live windows only.
7644 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7646 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7648 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7650 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7651 only under bidi iteration.
7653 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7655 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7657 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7659 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7660 Without this fix, the command to link temacs failed due to an
7661 undefined symbol __builtin_isnan. This is because
7662 /usr/include/iso/math_c99.h #defines isnan(x) to
7663 __builtin_isnan(x), but the bundled gcc, which identifies itself
7664 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7666 * floatfns.c (isnan): #undef, and then #define to a clone of
7668 (Fisnan): Always define, since it's always available now.
7669 (syms_of_floatfns): Always define isnan at the Lisp level.
7671 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7673 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7675 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7677 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7678 The previous code assumed that file offsets (off_t values) fit in
7679 EMACS_INT variables, which is not true on typical 32-bit hosts.
7680 The code messed up by falsely reporting buffer overflow in cases
7681 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7682 when "big" contains more than 2**29 bytes, even though this
7683 inserts just one byte and does not overflow the buffer.
7684 (Finsert_file_contents): Store file offsets as off_t
7685 values, not as EMACS_INT values. Check for overflow when
7686 converting between EMACS_INT and off_t. When checking for
7687 buffer overflow or for overlap, take the offsets into account.
7688 Don't use EMACS_INT for small values where int suffices.
7689 When checking for overlap, fix a typo: ZV was used where
7690 ZV_BYTE was intended.
7691 (Fwrite_region): Don't assume off_t fits into 'long'.
7692 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7694 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7696 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7698 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7700 sprintf-related integer and memory overflow issues (Bug#9412).
7702 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7703 (esprintf, exprintf, evxprintf): New functions.
7704 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7705 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7706 (modify_event_symbol): Do not assume that the length of
7707 name_alist_or_stem is safe to alloca and fits in int.
7708 (Fexecute_extended_command): Likewise for function name and binding.
7709 (Frecursion_depth): Wrap around reliably on integer overflow.
7710 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7711 since some callers pass EMACS_INT values.
7712 (Fsingle_key_description): Don't crash if symbol name contains more
7713 than MAX_ALLOCA bytes.
7714 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7715 (get_minibuffer): Arg is now EMACS_INT, not int.
7716 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7717 (esprintf, exprintf, evxprintf): New decls.
7718 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7720 * dbusbind.c (signature_cat): New function.
7721 (xd_signature, Fdbus_register_signal):
7722 Do not overrun buffer; instead, report string overflow.
7724 * dispnew.c (add_window_display_history): Don't overrun buffer.
7725 Truncate instead; this is OK since it's just a log.
7727 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7728 even if the time zone offset is outlandishly large.
7729 Don't mishandle offset == INT_MIN.
7731 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7732 when creating daemon; the previous buffer-overflow check was incorrect.
7734 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7735 which has the guts of the old verror function.
7737 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7738 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7740 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7741 (font_unparse_xlfd): Don't blindly alloca long strings.
7742 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7743 fits in int, when using sprintf. Use single snprintf to count
7744 length of string rather than counting it via multiple sprintfs;
7745 that's simpler and more reliable.
7746 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7747 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7748 sprintf, in case result does not fit in int.
7750 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7751 (fontset_from_font): Print it.
7753 * frame.c (tty_frame_count): Now printmax_t, not int.
7754 (make_terminal_frame, set_term_frame_name): Print it.
7755 (x_report_frame_params): In X, window IDs are unsigned long,
7756 not signed long, so print them as unsigned.
7757 (validate_x_resource_name): Check for implausibly long names,
7758 and don't assume name length fits in 'int'.
7759 (x_get_resource_string): Don't blindly alloca invocation name;
7760 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7763 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7764 (xg_check_special_colors, xg_set_geometry):
7765 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7767 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7768 Use esprintf, not sprintf, in case result does not fit in int.
7770 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7771 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7772 it as a large positive number.
7773 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7774 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7776 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7777 in case result does not fit in int.
7779 * print.c (float_to_string): Detect width overflow more reliably.
7780 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7781 buffer overrun. Don't assume list length fits in 'int'. Treat
7782 print length of 0 as 0, not as infinity; to be consistent with other
7783 uses of print length in this function. Don't overflow print length
7784 index. Don't assume hash table size fits in 'long', or that
7785 vectorlike size fits in 'unsigned long'.
7787 * process.c (make_process): Use printmax_t, not int, to format
7788 process-name gensyms.
7790 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7792 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7793 to avoid potential buffer overrun.
7795 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7796 if X resource line is longer than 512 bytes.
7798 * xfns.c (x_window): Make sprintf buffer a bit bigger
7799 to avoid potential buffer overrun.
7801 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7803 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7805 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7807 Integer overflow fixes for scrolling, etc.
7808 Without these, Emacs silently mishandles large integers sometimes.
7809 For example, "C-u 4294967297 M-x recenter" was treated as if
7810 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7812 * xdisp.c (try_window_id): Check Emacs fixnum range before
7813 converting to 'int'.
7815 * window.c (window_scroll_line_based, Frecenter):
7816 Check that an Emacs fixnum is in range before assigning it to 'int'.
7817 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7818 values converted from Emacs fixnums.
7819 (Frecenter): Don't wrap around a line count if it is out of 'int'
7820 range; instead, treat it as an extreme value.
7821 (Fset_window_configuration, compare_window_configurations):
7822 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7824 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7825 that can exceed INT_MAX. Check that EMACS_INT value is in range
7826 before assigning it to the (possibly-narrower) index.
7827 (match_limit): Don't assume that a fixnum can fit in 'int'.
7829 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7832 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7833 (Fvertical_motion): Don't wrap around LINES values that don't fit
7834 in 'int'. Instead, treat them as extreme values. This is good
7835 enough for windows, which can't have more than INT_MAX lines anyway.
7837 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7839 * Require libxml/parser.h to avoid compilation warning.
7841 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7843 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7844 since this reportedly can destroy thread storage.
7846 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7848 * syntax.c (find_defun_start): Update all cache variables if
7849 exiting early (Bug#9401).
7851 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7853 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7855 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7856 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7857 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7859 * term.c (tty_append_glyph): New function.
7860 (produce_stretch_glyph): Static function and its prototype deleted.
7862 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7865 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7867 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7868 when checking :margin (Bug#9390).
7869 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7870 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7871 so that the name doesn't mislead. All uses changed.
7873 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7875 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7878 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7880 * xdisp.c (move_it_to): Don't bail out early when reaching
7881 position beyond to_charpos, if we are scanning backwards.
7882 (move_it_vertically_backward): When DY == 0, make sure we get to
7883 the first character in the line after the newline.
7885 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7887 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7888 (ccl_driver): Do not generate an out-of-range pointer.
7889 (Fccl_execute_on_string): Remove unnecessary check for
7890 integer overflow, noted by Stefan Monnier in
7891 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7892 Remove a FIXME that didn't need fixing.
7893 Simplify the newly-introduced buffer reallocation code.
7895 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7897 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7899 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7901 Integer and memory overflow issues (Bug#9196).
7903 * doc.c (get_doc_string): Rework so that
7904 get_doc_string_buffer_size is the actual buffer size, rather than
7905 being 1 less than the actual buffer size; this makes xpalloc more
7908 * image.c (x_allocate_bitmap_record, cache_image):
7909 * xselect.c (Fx_register_dnd_atom):
7910 Simplify previous changes by using xpalloc.
7912 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7913 since either will do and ptrdiff_t is convenient with xpalloc.
7915 * charset.c (charset_table_size)
7916 (struct charset_sort_data.priority): Now ptrdiff_t.
7917 (charset_compare): Don't overflow if priorities differ greatly.
7918 (Fsort_charsets): Don't assume list length fits in int.
7919 Check for size-calculation overflow when allocating sort data.
7920 (syms_of_charset): Allocate an initial charset table that is
7921 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7923 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7925 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7926 The actual value is always <= INT_MAX, and leaving it unsigned made
7927 overflow checking harder.
7929 * dispextern.h (struct glyph_matrix.rows_allocated)
7930 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7931 with xpalloc. The values are still always <= INT_MAX.
7933 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7935 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7936 (SAFE_NALLOCA): New macro.
7938 * region-cache.c (struct boundary.pos, find_cache_boundary)
7939 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7940 (set_cache_region, invalidate_region_cache)
7941 (revalidate_region_cache, know_region_cache, region_cache_forward)
7942 (region_cache_backward, pp_cache):
7943 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7944 so that ptrdiff_t * can be passed to xpalloc.
7945 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7946 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7947 (pp_cache): Don't assume cache_len fits in int.
7948 * region-cache.h: Adjust extern decls to match.
7950 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7951 EMACS_INT, since either will do, for xpalloc.
7953 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7954 (xnmalloc, xnrealloc, xpalloc): New functions.
7956 * bidi.c (bidi_shelve_header_size): New constant.
7957 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7958 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7960 * bidi.c (bidi_cache_shrink):
7961 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7963 Don't update size of array until after memory allocation succeeds,
7964 because xmalloc/xrealloc may not return.
7965 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7966 now that we have proper integer overflow checking.
7967 (record_overlay_string, overlay_strings): Catch overflows when
7968 calculating size of overlay_str_buf.
7970 * callproc.c (Fcall_process): Check for size overflow when
7971 calculating size of args2.
7972 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7973 Normally we prefer signed values, but sticking with ptrdiff_t would
7974 require adding more-complicated checks.
7976 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7977 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7978 Redo buffer-overflow calculations to avoid integer overflow.
7979 Add a FIXME comment where memory seems to be over-allocated.
7981 * character.c (Fstring): Check for size-calculation overflow.
7983 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7984 unnecessary integer overflow. Check for size overflow.
7985 (encode_coding_object): Don't update size until xmalloc succeeds.
7987 * composite.c (get_composition_id): Check for overflow in glyph
7988 length calculations.
7990 Integer and memory overflow fixes for display code.
7991 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7992 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7993 (scrolling_window): Check for overflow in size calculations.
7994 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7996 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
7997 (row_table_size): Now ptrdiff_t, not int.
7998 (scrolling_window): Avoid overflow in size calculations.
7999 Don't update size until allocation succeeds.
8000 * fns.c (concat): Check for overflow in size calculations.
8001 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8002 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8003 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8005 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8006 (get_doc_string): Check for size calculation overflow.
8007 Don't update size until allocation succeeds.
8008 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8009 EMACS_INT, where ptrdiff_t will do.
8010 (Fsubstitute_command_keys): Check for string overflow.
8012 * editfns.c (set_time_zone_rule): Don't assume environment length
8014 (message_length): Now ptrdiff_t, not int.
8015 (Fmessage_box): Don't update size until allocation succeeds.
8016 Don't assume message length fits in int.
8017 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8019 * emacs.c (main): Do not reallocate argv, since there is a null at
8020 the end that can be overwritten, and this way there's no need to
8021 worry about size-calculation overflow.
8022 (sort_args): Check for size-calculation overflow.
8024 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8026 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8028 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8029 (x_set_scroll_bar_width, x_figure_window_size):
8030 Check for integer overflow.
8031 (x_set_alpha): Do not assume XINT fits in int.
8033 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8034 This is for the members text_lines, text_cols, total_lines, total_cols,
8035 where the system imposes an 'int' limit.
8037 * fringe.c (Fdefine_fringe_bitmap):
8038 Don't update size until alloc works.
8040 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8041 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8043 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8044 Check for size-calculation overflow.
8045 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8046 do, as we prefer signed integers.
8047 (id_to_widget.max_size, id_to_widget.used)
8048 (xg_store_widget_in_map, xg_remove_widget_from_map)
8049 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8050 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8051 Use and return ptrdiff_t, not int.
8052 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8053 * gtkutil.h: Change prototypes to match the above.
8055 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8056 are duplicate now that they've been promoted to lisp.h.
8057 (x_allocate_bitmap_record, x_alloc_image_color)
8058 (make_image_cache, cache_image, xpm_load):
8059 Don't update size until alloc is done.
8060 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8062 Check for size calculation overflow.
8063 (ct_colors_allocated_max): New constant.
8064 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
8067 * keyboard.c (read_char, menu_bar_items, tool_bar_items)

8069 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8070 Use ptrdiff_t, not int, to count maps.
8071 (read_char_minibuf_menu_prompt): Check for overflow in size
8072 calculations. Don't update size until allocation succeeds.
8073 Redo calculations to avoid overflow.

8083 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
8084 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8086 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8087 Now ptrdiff_t, not int.
8088 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8089 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
8091 * process.c (Fnetwork_interface_list): Check for overflow
8092 in size calculation.
8094 * region-cache.c (move_cache_gap): Check for size calculation overflow.

8097 overflow. Don't bother calling xmalloc when xrealloc will do.
8099 * search.c (Freplace_match): Check for size calculation overflow.
8100 (Fset_match_data): Don't assume list lengths fit in 'int'.
8102 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8103 for command line length. Do not attempt to address one before the
8104 beginning of an array, as that's not portable.
8106 * term.c (max_frame_lines): Remove; unused.
8107 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8109 (encode_terminal_code, calculate_costs): Check for size
8110 calculation overflow.

8113 done. Redo calculations to avoid overflow.
8114 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8116 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
8117 subtracting pointers.

8121 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
8122 Don't update size until alloc done.
8123 Redo size calculations to avoid overflow.

8132 Use ptrdiff_t, not int, for sizes.
8133 (Finternal_make_lisp_face, cache_face):
8134 Check for size calculation overflow.
8135 (cache_face): Treat size calculation overflows as if they were
8136 memory exhaustion (the usual treatment), rather than aborting.
8138 * xfns.c (x_encode_text, x_set_name_internal)
8139 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8140 sizes, since they can exceed INT_MAX in size. Check for size
8141 calculation overflow.
8143 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8144 (xg_select): Check for size calculation overflow.
8145 Don't update size until alloc done.
8147 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8148 as sprintf is limited to int lengths.
8150 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8151 (X_LONG_MIN): New macros.
8152 Use them to make the following changes clearer.
8153 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8154 This change doesn't affect the value now, but it may help remind
8155 future maintainers not to raise the value too much later.
8156 (SELECTION_QUANTUM): Remove, replacing with ...
8157 (selection_quantum): ... new function, which avoids overflow.
8159 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8160 assumption that selection length fits in 'int'.
8161 (x_reply_selection_request, x_handle_selection_request)
8162 (x_get_window_property, receive_incremental_selection)
8163 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8164 (lisp_data_to_selection_data, clean_local_selection_data):
8165 Use ptrdiff_t, not int, to record length of selection.
8166 (x_reply_selection_request, x_get_window_property)
8167 (receive_incremental_selection, x_property_data_to_lisp):
8168 Redo calculations to avoid overflow.
8169 (x_reply_selection_request): When sending hint, ceiling it at
8170 X_LONG_MAX rather than relying on wraparound overflow to send
8172 (x_get_window_property, receive_incremental_selection)
8173 (lisp_data_to_selection_data, x_property_data_to_lisp):
8174 Check for size-calculation overflow.
8175 (x_get_window_property, receive_incremental_selection)
8176 (lisp_data_to_selection_data, Fx_register_dnd_atom):
8177 Don't store size until memory allocation succeeds.
8178 (x_get_window_property): Plug memory leak on memory exhaustion.
8179 Don't double-block input; malloc is safe here. Don't assume 2**34
8180 - 4 fits in unsigned long. Add an xassert to check
8181 XGetWindowProperty overflow. Be more careful about overflow
8182 calculations, and distinguish size from memory overflow better.
8183 (receive_incremental_selection): When tracing, don't assume
8184 unsigned int is less than INT_MAX.
8185 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8186 harmful) conversions of unsigned short to int.
8187 (lisp_data_to_selection_data): Don't assume that integers
8188 in the range -65535 through -1 fit in an X unsigned short.
8189 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8190 result parameters unless successful. Rely on cons_to_unsigned
8191 to report problems with elements; the old code wasn't right anyway.
8192 (x_check_property_data): Check for int overflow; we cannot use
8193 a wider type due to X limits.
8194 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8196 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8198 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8199 (x_term_init): Check for size calculation overflow.
8200 (x_color_cells): Don't store size until memory allocation succeeds.

8225 * image.c (xpm_get_color_table_h):
8226 * lisp.h (hash_lookup, hash_put):
8227 * minibuf.c (Ftest_completion):
8228 Use ptrdiff_t for hash table indexes, not int (which is too
8229 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8230 32-bit --with-wide-int hosts).
8232 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8233 Add a FIXME comment about memory leaks.
8234 (syms_of_charset): Don't assume xmalloc returns.
8236 Don't assume that stated character widths fit in int.
8237 * character.c (Fchar_width, c_string_width, lisp_string_width):
8238 * character.h (CHAR_WIDTH):
8239 * indent.c (MULTIBYTE_BYTES_WIDTH):
8240 Use sanitize_char_width to avoid undefined and/or bad behavior
8241 with outlandish widths.
8242 * character.h (sanitize_tab_width): Rename from sanitize_width,
8243 now that we have two such functions. All uses changed.
8244 (sanitize_char_width): New inline function.
8246 Don't assume that tab-width fits in int.
8247 * character.h (sanitize_width): New inline function.
8248 (SANE_TAB_WIDTH): New macro.

8262 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8263 (x_send_scroll_bar_event): Likewise. Check that the size does not
8264 exceed limits imposed by XClientMessageEvent, as well as the usual
8265 ptrdiff_t and size_t limits.
8267 * keyboard.c: Overflow, signedness and related fixes.
8268 (make_lispy_movement): Use same integer type in forward decl
8269 that is used in the definition.
8270 (read_key_sequence, keyremap_step):
8271 Change bufsize argument back to int, undoing my 2011-03-30 change.
8272 We prefer signed types, and int is wide enough here.
8273 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8274 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8275 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8276 length, not size_t. Use ptrdiff_t for index, not int.
8277 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8278 possibility of integer overflow.
8280 Overflow, signedness and related fixes for images.

8290 * xdisp.c (calc_pixel_width_or_height):
8291 * xfns.c (image_cache_refcount):
8292 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8293 on typical 64-bit hosts.
8295 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8296 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8301 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8302 (lookup_image): Remove unnecessary tests.
8303 (xbm_image_p): Locals are now of int, not EMACS_INT,
8304 since parse_image_check makes sure they fit into int.
8305 (png_load, gif_load, svg_load_image):
8306 Prefer int to unsigned where either will do.
8307 (tiff_handler): New function, combining the cores of the
8308 old tiff_error_handler and tiff_warning_handler.
8309 This function is rewritten to use vsnprintf and thereby avoid
8310 stack buffer overflows. It uses only the features of vsnprintf
8311 that are common to both POSIX and native Microsoft.
8312 (tiff_error_handler, tiff_warning_handler): Use it.
8313 (tiff_load, gif_load, imagemagick_load_image):
8314 Don't assume :index value fits in 'int'.
8315 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8316 (imagemagick_load_image): Check that crop parameters fit into
8317 the integer types that MagickCropImage accepts. Don't assume
8318 Vimagemagick_render_type has a nonnegative value. Don't assume
8319 size_t fits in 'long'.
8320 (gs_load): Use printmax_t to print the widest integers possible.

8328 2011-08-25 Eli Zaretskii <eliz@gnu.org>
8330 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8331 the display spec is of the form `(space ...)'.
8332 (handle_display_spec): Return the value returned by
8333 handle_single_display_spec, not just 1 or zero.
8334 (handle_single_display_spec): If the display spec is of the form
8335 `(space ...)', and specifies display in the text area, return 2
8337 (try_cursor_movement): Check for the need to scroll more
8338 accurately, and prefer exact match for point under bidi.
8339 Don't advance `row' beyond the last row of the window.
8341 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8342 into disp_prop; all users changed.
8344 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8345 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8346 for the text covered by the display property.
8348 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8350 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8357 buffers, return left-to-right.
8358 (set_cursor_from_row): Consider candidate row a win if its glyph
8359 represents a newline and point is on that newline. Fixes cursor
8360 positioning on the newline at EOL of R2L text within L2R
8361 paragraph, and vice versa.
8362 (try_cursor_movement): Check continued rows, in addition to
8363 continuation rows. Fixes unwarranted scroll when point enters a
8364 continued line of R2L text within an L2R paragraph, or vice versa.
8365 (cursor_row_p): Consider the case of point being equal to
8366 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8367 from the end of a short line to the beginning of a continued line
8368 of R2L text within L2R paragraph.
8369 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8370 composed characters.
8372 * bidi.c (bidi_check_type): Use xassert.

8385 2011-08-22 Kenichi Handa <handa@m17n.org>
8387 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8388 extra slot even if the purpose is char-code-property-table.
8390 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8392 * xdisp.c (redisplay_window): When computing centering_position,
8393 account for the height of the header line. (Bug#8874)
8395 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8396 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8397 candidate is selected by the mouse, and that candidate has a
8398 composed character under the mouse.
8400 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8401 coordinates reported by pos-visible-in-window-p for a composed
8402 character in column zero.
8404 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8406 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8408 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8410 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8411 consider it a hit if to_charpos is anywhere in the range of the
8412 composed buffer positions.
8414 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8416 * image.c (gif_load): Don't assume that each subimage has the same
8417 dimensions as the base image. Handle disposal method that is
8418 "undefined" by the gif spec (Bug#9335).
8420 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8422 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8423 (Fcondition_case): Document `debug' symbol in error handler.
8425 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8427 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8428 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8429 from an Org mode buffer to a Speedbar frame.
8431 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8432 a composition, take its buffer position from IT->cmp_it.charpos.
8433 Fixes cursor positioning at the beginning of a line that begins
8434 with a composed character.
8436 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8438 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8439 character bidirectional type, use STRONG_L instead. Fixes crashes
8440 in a buffer produced by `describe-categories'.
8442 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8443 members before the level stack, so they would be saved and
8444 restored when copying iterator state. Fixes incorrect reordering
8445 around TABs covered by display properties.
8447 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8449 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8457 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8459 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8460 has no `load' handler, try opening the file locally. (Bug#9311)
8462 2011-08-16 Ken Brown <kbrown@cornell.edu>

8484 [CYGWIN] (special_realloc): New function.
8485 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8486 requests to realloc storage in the static heap.

8519 * xdisp.c (move_it_in_display_line_to): Don't invoke
8520 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8521 ppos_it. Fixes vertical cursor motion when line beginning is
8522 covered by an image. (Bug#9296)
8524 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8526 * nsterm.h (ns_run_ascript): Declare.

8529 * nsfns.m (as_script, as_result, as_status): New static variables.
8530 (ns_run_ascript): New function.
8531 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8532 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8533 the event loop. Get status from as_status (Bug#7276).
8535 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8536 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8537 the event loop (Bug#7276).
8539 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8541 * gnutls.c (QCgnutls_bootprop_priority)

8562 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8563 (Fnetwork_interface_list): Allocate in increments of bytes instead
8564 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8565 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8567 (struct ifflag_def): notrailers is smart on OSX.
8568 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8569 Get hardware address with getifaddrs if available.
8571 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8573 * xdisp.c (iterate_out_of_display_property): xassert that
8574 IT->position is set to within IT->object's boundaries. Break from
8575 the loop as soon as EOB is reached; avoids infloops in redisplay
8576 when IT->position is set up wrongly due to some bug.
8577 Set IT->current to match the bidi iterator unconditionally.
8578 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8579 entry. Force push_it to save on the stack the current
8580 buffer/string position, to be restored by pop_it. Fix flags in
8581 the iterator structure wrt the object coming from a display
8582 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8583 properties. (Bug#9284)
8585 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8587 * fontset.c (fontset_get_font_group): Add proper type checks.

8595 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8597 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8599 * xdisp.c (forward_to_next_line_start): Allow to use the
8600 no-display-properties-and-no-overlays under bidi display.
8601 Set disp_pos in the bidi iterator to avoid searches for display
8602 properties and overlays.
8604 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8606 * editfns.c (Fset_time_zone_rule): Document relationship with the
8609 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to

8612 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8614 * composite.c (autocmp_chars): Don't reset point. That is done by
8615 restore_point_unwind (Bug#5984).
8617 2011-08-07 Juri Linkov <juri@jurta.org>
8619 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8620 to show the arg `TIME' instead of `TIMEVAL'.
8622 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8624 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8625 display property strides EOL and includes a newline, as in
8626 longlines-mode. (Bug#9254)
8627 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8628 word-wrap under bidirectional display. (Bug#9224)
8630 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8631 is non-zero, even if the data buffer is NULL. Fixes a crash in
8632 vertical-motion with longlines-mode. (Bug#9254)
8634 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8636 * bidi.c <bidi_cache_total_alloc>: Now static.
8637 (bidi_initialize): Initialize bidi_cache_total_alloc.
8639 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8642 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8643 amount allocated this far in `bidi_cache_total_alloc'.
8644 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8645 non-zero, only free the data buffer without restoring the cache
8646 contents. All callers changed.
8648 * dispextern.h (bidi_unshelve_cache): Update prototype.
8650 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8651 (move_it_in_display_line, move_it_to)
8652 (move_it_vertically_backward, move_it_by_lines): Replace the call
8653 to xfree to an equivalent call to bidi_unshelve_cache.
8654 (move_it_in_display_line_to): Fix logic of returning
8655 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8657 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8659 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8660 came from a string character with a `cursor' property. (Bug#9229)
8662 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8664 * Makefile.in (LIB_PTHREAD): New variable.
8665 (LIBES): Add LIB_PTHREAD (Bug#9216).
8667 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8668 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8670 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8672 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8674 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8676 * xterm.c (x_find_topmost_parent): New function.
8677 (x_set_frame_alpha): Find topmost parent window with
8678 x_find_topmost_parent and set the property there also (bug#9181).
8679 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8681 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8683 * callproc.c (Fcall_process): Avoid vfork clobbering
8684 the local vars buffer, coding_systems, current_dir.
8686 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8688 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8690 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8692 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8693 so that it is not optimized away.
8695 * xdisp.c (compute_display_string_pos): Remove unused local.
8697 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8699 Fix slow cursor motion and scrolling in large buffers with
8700 selective display, like Org Mode buffers. (Bug#9218)
8702 * dispextern.h (struct bidi_it): New member disp_prop_p.
8704 * xdisp.c: Remove one-slot cache of display string positions.
8705 (compute_display_string_pos): Accept an additional argument
8706 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8707 for a display string or property. If found, set DISP_PROP_P
8710 * bidi.c (bidi_fetch_char): Accept an additional argument
8711 DISP_PROP_P, and pass it to compute_display_string_pos.
8712 Only handle text covered by a display string if DISP_PROP_P is returned
8713 non-zero. All callers of bidi_fetch_char changed.
8715 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8717 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8719 2010-12-03 Don March <don@ohspite.net>
8721 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8722 last character M-[char] is translated to ESC [char] (bug#7541).
8724 2011-08-02 Kenichi Handa <handa@m17n.org>
8726 * lisp.h (uniprop_table): Extern it.
8728 * chartab.c (uniprop_table): Make it non-static.
8730 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8732 * xdisp.c (forward_to_next_line_start): Accept additional argument
8733 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8735 (reseat_at_next_visible_line_start): Use the bidi iterator state
8736 returned by forward_to_next_line_start to restore the state of
8737 it->bidi_it after backing up to previous newline. (Bug#9212)
8739 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8741 * regex.c (re_comp): Protoize.
8742 (re_exec): Fix return type.
8743 (regexec): Fix type of `ret'. (Bug#9203)
8745 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8747 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8748 This is needed if max-image-size is a floating-point number.
8750 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8752 * print.c (print_object): Print empty symbol as ##.
8754 * lread.c (read1): Read ## as empty symbol.
8756 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8758 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8759 setting frame foreground color (Bug#9175).
8760 (x_set_background_color): Likewise.
8762 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8763 contents (Bug#9176).
8764 (EmacsTooltip -init): Remove bezels and add shadows to
8767 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8768 or scroll bar (Bug#8470).
8770 * nsfont.m (nsfont_open): Remove assignment to voffset and
8771 unnecessary vars hshink, expand, hd, full_height, min_height.
8772 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8774 * nsterm.h (nsfont_info): Remove voffset field.
8776 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8778 Implement strike-through and overline on NextStep (Bug#8863).
8780 * nsfont.m (nsfont_open): Use underline position provided by font,
8781 instead of hard-coded value of 2.
8782 (nsfont_draw): Call ns_draw_text_decoration instead.
8784 * nsterm.h: Add declaration for ns_draw_text_decoration.
8786 * nsterm.m (ns_draw_text_decoration): New function for drawing
8787 underline, overline, and strike-through.
8788 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8789 ns_draw_text_decoration. Change treatment of cursor drawing to
8790 accommodate underlining, etc.
8792 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8794 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8797 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8799 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8800 Without this fix, if a signal arrives just after memory fills up,
8801 'malloc' might be invoked reentrantly.
8803 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8804 In other words, assume that every image size is allowed, on non-X
8805 hosts. This assumption is probably wrong, but it lets Emacs compile.
8807 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8809 * regex.c (re_iswctype): Convert return values to boolean.
8811 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8813 * xdisp.c (compute_display_string_pos): Don't use cached display
8814 string position if the buffer had its restriction changed.
8817 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8819 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8821 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8823 Integer signedness and overflow and related fixes. (Bug#9079)
8825 * bidi.c: Integer size and overflow fixes.
8826 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8827 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8828 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8829 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8830 (bidi_find_other_level_edge):
8831 Use ptrdiff_t instead of EMACS_INT where either will do.
8832 This works better on 32-bit hosts configured --with-wide-int.
8833 (bidi_cache_ensure_space): Check for size-calculation overflow.
8834 Use % rather than repeated addition, for better worst-case speed.
8835 Don't set bidi_cache_size until after xrealloc returns, because it
8837 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8838 (bidi_cache_ensure_space): Also check that the bidi cache size
8839 does not exceed that of the largest Lisp string or buffer. See Eli
8840 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8842 * alloc.c (__malloc_size_t): Remove.
8843 All uses replaced by size_t. See Andreas Schwab's note
8844 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8846 * image.c: Improve checking for integer overflow.
8847 (check_image_size): Assume that f is nonnull, since
8848 it is always nonnull in practice. This is one less thing to
8849 worry about when checking for integer overflow later.
8850 (x_check_image_size): New function, which checks for integer
8851 overflow issues inside X.
8852 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8853 This removes the need for a memory_full check.
8854 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8855 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8856 (xbm_read_bitmap_data): Change locals back to 'int', since
8857 their values must fit in 'int'.
8858 (xpm_load_image, png_load, tiff_load):
8859 Invoke x_create_x_image_and_pixmap earlier,
8860 to avoid much needless work if the image is too large.
8861 (tiff_load): Treat overly large images as if
8862 x_create_x_image_and_pixmap failed, not as malloc failures.
8863 (gs_load): Use x_check_image_size.
8865 * gtkutil.c: Omit integer casts.
8866 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8867 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8869 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8871 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8872 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8873 would wrongly return t on a 64-bit host.
8875 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8876 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8877 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8878 and therefore cause GCC to emit a bogus diagnostic in some cases.
8880 * image.c: Integer signedness and overflow and related fixes.
8881 This is not an exhaustive set of fixes, but it's time to
8882 record what I've got.
8883 (lookup_pixel_color, check_image_size): Remove redundant decls.
8884 (check_image_size): Don't assume that arbitrary EMACS_INT values
8885 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8886 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8887 (tiff_load, imagemagick_load_image):
8888 Check for overflow in size calculations.
8889 (x_create_x_image_and_pixmap): Remove unnecessary test for
8890 xmalloc returning NULL; that can't happen.
8891 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8892 (xpm_color_bucket): Use better integer hashing function.
8893 (xpm_cache_color): Don't possibly over-allocate memory.
8894 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8895 (gif_memory_source):
8896 Use ptrdiff_t, not int or size_t, to record sizes.
8897 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8898 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8899 either works, as we prefer signed integers.
8900 (tiff_read_from_memory, tiff_write_from_memory):
8901 Return tsize_t, not size_t, since that's what the TIFF API wants.
8902 (tiff_read_from_memory): Don't fail simply because the read would
8903 go past EOF; instead, return a short read.
8904 (tiff_load): Omit no-longer-needed casts.
8905 (Fimagemagick_types): Don't assume size fits into 'int'.
8907 Improve hashing quality when configured --with-wide-int.
8908 * fns.c (hash_string): New function, taken from sxhash_string.
8909 Do not discard information about ASCII character case; this
8910 discarding is no longer needed.
8911 (sxhash-string): Use it. Change sig to match it. Caller changed.
8912 * lisp.h: Declare it.
8913 * lread.c (hash_string): Remove, since we now use fns.c's version.
8914 The fns.c version returns a wider integer if --with-wide-int is
8915 specified, so this should help the quality of the hashing a bit.
8917 * emacs.c: Integer overflow minor fix.
8918 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8919 Define only if GNU_LINUX.
8920 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8922 * dispnew.c: Integer signedness and overflow fixes.
8923 Remove unnecessary forward decls, that were a maintenance hassle.
8924 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8926 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8927 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8928 (prepare_desired_row, line_draw_cost):
8929 Use int, not unsigned, where either works.
8930 (save_current_matrix, restore_current_matrix):
8931 Use ptrdiff_t, not size_t, where either works.
8932 (init_display): Check for overflow more accurately, and without
8933 relying on undefined behavior.
8935 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8936 Remove, replacing with the new symbols in lisp.h. All uses changed.
8937 * fileio.c (make_temp_name):
8938 * filelock.c (lock_file_1, lock_file):
8939 * xdisp.c (message_dolog):
8940 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8941 Use pMd etc. instead.
8942 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8943 replacing the pWIDE etc. symbols removed from editfns.c.
8945 * keyboard.h (num_input_events): Now uintmax_t.
8946 This is (very slightly) less likely to mess up due to wraparound.
8949 * buffer.c: Integer signedness fixes.
8950 (alloc_buffer_text, enlarge_buffer_text):
8951 Use ptrdiff_t rather than size_t when either will do, as we prefer
8954 * alloc.c: Integer signedness and overflow fixes.
8955 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8956 (__malloc_size_t): Default to size_t, not to int.
8957 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8958 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8959 Prefer ptrdiff_t to size_t when either would do, as we prefer
8961 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8962 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8963 Now const. Initialize with values that are in range even if char
8965 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8966 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8967 These functions do the right thing with sizes > 2**32.
8968 (check_depth): Now ptrdiff_t, not int.
8969 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8970 Adjust to new way of storing sizes. Check for size overflow bugs
8972 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8973 slightly wrong anyway, as it missed one instance of
8974 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8975 (refill_memory_reserve): Omit needless cast to size_t.
8976 (mark_object_loop_halt): Mark as externally visible.
8978 * xselect.c: Integer signedness and overflow fixes.
8979 (Fx_register_dnd_atom, x_handle_dnd_message):
8980 Use ptrdiff_t, not size_t, since we prefer signed.
8981 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8982 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8983 x_dnd_atoms_size and x_dnd_atoms_length.
8985 * doprnt.c: Prefer signed to unsigned when either works.
8987 * doprnt.c (doprnt):
8989 * xdisp.c (vmessage):
8990 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8991 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8992 prefer signed arithmetic to avoid comparison confusion.
8993 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8994 but is a bit tricky.
8996 Assume freestanding C89 headers, string.h, stdlib.h.
8997 * data.c, doprnt.c, floatfns.c, print.c:
8998 Include float.h unconditionally.
8999 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9000 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9001 * regex.c: Likewise for stddef.h, string.h.
9002 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9003 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9004 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9005 (STDC_HEADERS): Remove obsolete defines.
9006 * sysdep.c: Include limits.h unconditionally.
9008 Assume support for memcmp, memcpy, memmove, memset.
9009 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9010 * regex.c (memcmp, memcpy):
9011 Remove; we assume C89 now.
9013 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9014 (__malloc_safe_bcopy): Remove; no longer needed.
9016 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9017 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9018 well either way, and we prefer signed to unsigned.
9020 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9022 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9023 closes the connection while we're reading (bug#9182).
9025 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9027 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9028 are specified (Bug#9168).
9030 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9032 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9033 Found by GCC static checking and --with-wide-int on a 32-bit host.
9035 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9037 * xdisp.c (compute_display_string_pos): Fix logic of caching
9038 previous display string position. Initialize cached_prev_pos to
9039 -1. Fixes slow-down at the beginning of a buffer.
9041 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9043 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9044 for attrs[LFACE_FONTSET_INDEX].
9046 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9048 * xml.c (parse_region): Remove unused local
9049 that was recently introduced.
9051 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9053 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9054 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9056 * xdisp.c (move_it_in_display_line_to): Record the best matching
9057 position for TO_CHARPOS while scanning the line, and restore it on
9058 exit if none of the characters scanned was an exact match.
9059 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9060 when exact match is impossible due to invisible text, and the
9061 lines are truncated.
9063 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9065 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9068 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9070 Fix a significant slow-down of cursor motion with C-n, C-p,
9071 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9072 auto-repeat under bidi redisplay in fontified buffers.
9073 * xdisp.c (compute_stop_pos_backwards): New function.
9074 (next_element_from_buffer): Call compute_stop_pos_backwards to
9075 find a suitable prev_stop when we find ourselves before
9077 (reseat): Don't look for prev_stop, as that could mean a very long
9079 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9080 <cached_disp_overlay_modiff>: Cache for last found display string
9082 (compute_display_string_pos): Return the cached position if asked
9083 about the same buffer in the same area of character positions, and
9084 the buffer wasn't changed since the time the display string
9085 position was cached.
9087 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9089 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9090 is an integer, which is important for empty lines. (Bug#9149)
9092 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9094 * frame.c (Fmodify_frame_parameters): In tty case, update the
9095 default face if necessary (Bug#4238).
9097 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9099 * editfns.c (Fstring_to_char): No need to explain what a character
9100 is in the docstring (Bug#6576).
9102 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9104 * xml.c (parse_region): Make sure we always return a tree.
9106 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9108 * xml.c (parse_region): If a document contains only comments,
9111 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9113 * xml.c (make_dom): Return comments, too.
9115 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9118 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9119 and the surrounding thread.
9120 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9121 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9122 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9124 * s/openbsd.h (BROKEN_SIGIO): Define.
9125 * unexelf.c (unexec) [__OpenBSD__]:
9126 Don't update the .mdebug section of the Alpha COFF symbol table.
9128 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9130 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9133 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>

9136 This fixes some race conditions on the permissions of any newly
9139 * alloc.c (valid_pointer_p): Use pipe, not open.
9140 This fixes some permissions issues when debugging.
9142 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9143 If fchown fails to set both uid and gid, try to set just gid,
9144 as that is sometimes allowed. Adjust the file's mode to eliminate
9145 setuid or setgid bits that are inappropriate if fchown fails.
9147 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9149 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9150 to compare Lisp_Objects.

9161 symbol character follows.
9163 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9165 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9166 This works around a problem with the previous change to Fcopy_file.
9167 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9168 and without this change, GCC might complain about discarding
9169 fchown's return value.
9171 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9173 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9175 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9177 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9179 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9181 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9182 it's used from the C level.
9184 * process.c: Use the same condition for POLL_FOR_INPUT in both
9185 keyboard.c and process.c (bug#1858).
9187 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9194 * doc.c (Fsubstitute_command_keys): Revert last change.
9196 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9198 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9199 quotes the next character, and doesn't affect other longer
9200 sequences (bug#8935).
9202 * lread.c (syms_of_lread): Clarify that is isn't only
9203 `eval-buffer' and `eval-defun' that's affected by
9204 `lexical-binding' (bug#8460).

9208 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9209 bidi redisplay when a line includes both an image and is truncated.

9214 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9215 (elsz): Now a signed constant, not a size_t var. We prefer signed
9216 types to unsigned, to avoid integer comparison confusion. Without
9217 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9218 "cannot optimize loop, the loop counter may overflow", a symptom
9220 * indent.c (Fvertical_motion): Mark locals as initialized.
9221 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9223 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9225 * search.c (Fre_search_backward): Mention `case-fold-search' in
9226 all the re_search_* functions (bug#8138).
9228 * keyboard.c (Fopen_dribble_file): Document when the file is

9246 buffer position was specified. Initialize paragraph_embedding to
9248 (reseat_to_string): Initialize the bidi iterator.
9249 (display_string): If we need to ignore text properties of
9250 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

9261 Fix calculation of the object to scan. Fixes an error when using
9263 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9264 base_level_stop; instead, set base_level_stop to BEGV.
9265 Fixes crashes in vertical-motion.
9266 (next_element_from_buffer): Improve commentary for when
9267 the iterator is before prev_stop.
9268 (init_iterator): Initialize bidi_p from the default value of
9269 bidi-display-reordering, not from buffer-local value. Use the
9270 buffer-local value only if initializing for buffer iteration.
9271 (handle_invisible_prop): Support invisible properties on strings
9272 that are being bidi-reordered.
9273 (set_iterator_to_next): Support bidi reordering of C strings and

9291 parts of next_element_from_buffer, next_element_from_string, and
9292 next_element_from_c_string.

9309 pushed the iterator stack, restore the internal state of the bidi
9310 iterator by calling bidi_pop_it same number of times.
9311 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9312 and we are bidi-iterating, don't decrement the iterator position;
9313 instead, set the first_elt flag in the bidi iterator, to produce

9786 Random fixes. E.g., (random) never returned negative values.
9787 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9788 subseconds part to the entropy, as that's a bit more random.
9789 Prefer signed to unsigned, since the signedness doesn't matter and
9790 in general we prefer signed. When given a limit, use a
9791 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9792 latter isn't right if USE_2_TAGS_FOR_INTS.
9793 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9794 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9807 This is more efficient than Ffile_directory_p and avoids a minor race.
9809 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9811 * buffer.c (Foverlay_put): Say what the return value is
9814 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9817 (barf_or_query_if_file_exists): Make the "File is a directory"
9818 error be more correct.
9820 * fns.c (Frequire): Remove the mention of the .gz files, since
9821 that's installation-specific, but keep the mention of

9826 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9837 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9939 * eval.c (struct backtrace): Simplify and port the data structure.
9940 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9941 signed bit field, as this assumption is not portable and it makes
9942 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9943 "char debug_on_exit : 1" as this is not portable either; instead,
9944 use the portable "unsigned int debug_on_exit : 1". Remove unused
9945 member evalargs. Remove obsolete comments about cc bombing out.

10037 pending. Suggested by Jan Djärv (Bug#8869).
10039 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
10041 Use gnulib's dup2 module instead of rolling our own.
10042 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
10044 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10046 * dispnew.c (scrolling_window): Before scrolling, turn off a

10109 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10111 Integer and buffer overflow fixes (Bug#8873).
10113 * print.c (printchar, strout): Check for string overflow.
10114 (PRINTPREPARE, printchar, strout):
10115 Don't set size unless allocation succeeds.
10117 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10118 for sizes. Check for string overflow more accurately.
10119 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10121 * macros.c: Integer and buffer overflow fixes.
10122 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10123 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10124 Use ptrdiff_t, not int, for sizes.
10125 Don't increment bufsize until after realloc succeeds.
10126 Check for size-calculation overflow.
10127 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10129 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10131 * lread.c: Integer overflow fixes.
10132 (read_integer): Radix is now EMACS_INT, not int,
10133 to improve quality of diagnostics for out-of-range radices.
10134 Calculate buffer size correctly for out-of-range radices.
10135 (read1): Check for integer overflow in radices, and in
10136 read-circle numbers.
10137 (read_escape): Avoid int overflow.
10138 (Fload, openp, read_buffer_size, read1)
10139 (substitute_object_recurse, read_vector, read_list, map_obarray):
10140 Use ptrdiff_t, not int, for sizes.

10155 2011-06-22 Leo Liu <sdl.web@gmail.com>
10157 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10158 Move to minibuffer.el.
10160 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10162 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10163 The following patches are for when GLYPH_DEBUG && !XASSERT.
10164 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10165 * dispnew.c (flush_stdout):
10166 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10167 Mark as externally visible.
10168 * dispnew.c (check_window_matrix_pointers): Now static.
10169 * dispnew.c (window_to_frame_vpos):
10170 * xfns.c (unwind_create_frame):
10171 * xterm.c (x_check_font): Remove unused local.
10172 * scroll.c (CHECK_BOUNDS):
10173 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10174 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10175 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10176 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10177 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10179 (debug_method_add): Use va_list and vsprintf rather than relying
10180 on undefined behavior with wrong number of arguments.
10181 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10182 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10183 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10184 since we're not interested in debugging glyphs with old libraries.
10185 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10186 GCC 4.6.0's static checking.
10188 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10190 Integer overflow and signedness fixes (Bug#8873).

10199 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10200 (x_create_bitmap_from_xpm_data):
10201 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10202 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10204 * xfaces.c (load_pixmap):

10206 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10207 (.bitmaps_last, struct x_output.icon_bitmap):
10208 Use ptrdiff_t, not int, for bitmap indexes.
10209 (x_allocate_bitmap_record): Check for size overflow.
10210 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10212 Use ptrdiff_t, not int, for overlay counts.
10213 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10214 * editfns.c (overlays_around, get_pos_property):
10215 * textprop.c (get_char_property_and_overlay):
10216 * xdisp.c (next_overlay_change, note_mouse_highlight):
10217 * xfaces.c (face_at_buffer_position):
10218 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10219 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10220 (Fnext_overlay_change, Fprevious_overlay_change)
10221 (mouse_face_overlay_overlaps, Foverlays_in):
10222 Use ptrdiff_t, not int, for sizes.
10223 (overlays_at, overlays_in): Check for size-calculation overflow.
10225 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10227 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10228 (x_session_initialize): Do not assume string length fits in int.
10230 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10231 This is unlikely, but can occur if DPI is outlandish.
10233 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10234 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10236 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10237 * xrdb.c (magic_file_p, search_magic_path):
10238 Omit last arg SUFFIX; it was always 0. All callers changed.
10239 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10241 * xfont.c (xfont_match): Avoid need for strlen.
10243 * xfns.c: Don't assume strlen fits in int.
10244 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10246 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10247 not unsigned long, as we prefer signed integers. All callers changed.
10248 Detect integer overflow in repeat count.
10249 (message_dolog): Don't assume print length fits in 39 bytes.
10250 (display_mode_element): Don't assume strlen fits in int.
10252 * termcap.c: Don't assume sizes fit in int and never overflow.
10253 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10254 (gobble_line): Check for size-calculation overflow.
10256 * minibuf.c (Fread_buffer):
10257 * lread.c (intern, intern_c_string):
10258 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

10262 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10264 * font.c: Don't assume string length fits in int.
10265 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10266 Use ptrdiff_t, not int.
10267 (font_intern_prop): Don't assume string length fits in int.
10268 Don't assume integer property fits in fixnum.
10269 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10271 * filelock.c: Fix some buffer overrun and integer overflow issues.
10272 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10273 Reformulate so as not to need the command string.
10274 Invoke gzip -cd rather than gunzip, as it's more portable.
10275 (lock_info_type, lock_file_1, lock_file):
10276 Don't assume pid_t and time_t fit in unsigned long.
10277 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10278 (current_lock_owner): Prefer signed type for sizes.
10279 Use memcpy, not strncpy, where memcpy is what is really wanted.
10280 Don't assume (via atoi) that time_t and pid_t fit in int.
10281 Check for time_t and/or pid_t out of range, e.g., via a network share.
10282 Don't alloca where an auto var works fine.
10284 * fileio.c: Fix some integer overflow issues.
10285 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10286 Don't assume string length fits in int.
10287 (directory_file_name): Don't assume string length fits in long.
10288 (make_temp_name): Don't assume pid fits in int, or that its print
10289 length is less than 20.
10291 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10293 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10295 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10297 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10298 We prefer signed integers, even for size calculations.
10300 * emacs.c: Don't assume string length fits in 'int'.
10301 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10302 (main): Don't invoke strlen when not needed.
10304 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10305 (XD_DEBUG_MESSAGE): Don't waste a byte.
10307 * callproc.c (getenv_internal_1, getenv_internal)
10308 (Fgetenv_internal):
10309 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10311 * lread.c (invalid_syntax): Omit length argument.
10312 All uses changed. This doesn't fix a bug, but it simplifies the
10313 code away from its former Hollerith-constant appearance, and it's
10314 one less 'int' to worry about when looking at integer-overflow issues.
10315 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10317 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10318 This didn't break anything, but it didn't help either.
10319 It's confusing to put a bogus integer in a place where the actual
10320 value does not matter.
10321 (LIST_END_P): Remove unused macro and its bogus comment.
10322 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10324 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10325 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10327 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10328 We prefer signed types, and the value cannot exceed the EMACS_INT
10329 range anyway (because otherwise the length would not be representable).
10330 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10331 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10332 This avoids a GCC warning when WIDE_EMACS_INT.
10334 * indent.c (sane_tab_width): New function.
10335 (current_column, scan_for_column, Findent_to, position_indentation)
10336 (compute_motion): Use it. This is just for clarity.
10337 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10339 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

10342 * composite.c (composition_gstring_put_cache):
10343 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10345 * editfns.c, insdel.c:
10346 Omit unnecessary forward decls, to simplify future changes.
10348 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10350 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10352 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10353 Use much-faster test for byte-length change.
10354 Don't assume string byte-length fits in 'int'.
10355 Check that character arg fits in 'int'.
10356 (mapcar1): Declare byte as byte, for clarity.
10358 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10360 * fns.c (concat): Catch string overflow earlier.
10361 Do not rely on integer wraparound.
10363 * dispextern.h (struct it.overlay_strings_charpos)
10364 (struct it.selective): Now EMACS_INT, not int.
10365 * xdisp.c (forward_to_next_line_start)
10366 (back_to_previous_visible_line_start)
10367 (reseat_at_next_visible_line_start, next_element_from_buffer):
10368 Don't arbitrarily truncate the value of 'selective' to int.
10370 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10372 * composite.c: Don't truncate sizes to 'int'.
10373 (composition_gstring_p, composition_reseat_it)
10374 (composition_adjust_point): Use EMACS_INT, not int.
10375 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10376 not EMACS_UINT, for indexes.
10378 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10380 * buffer.c: Include <verify.h>.
10381 (struct sortvec.priority, struct sortstr.priority):
10382 Now EMACS_INT, not int.
10383 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10384 (struct sortstr.size, record_overlay_string)
10385 (struct sortstrlist.size, struct sortlist.used):
10386 Don't truncate size to int.
10387 (record_overlay_string): Check for size-calculation overflow.
10388 (init_buffer_once): Check at compile-time, not run-time.
10390 2011-06-22 Jim Meyering <meyering@redhat.com>
10392 Don't leak an XBM-image-sized buffer
10393 * image.c (xbm_load): Free the image buffer after using it.
10395 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10398 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10399 that Sun C diagnosed.
10400 * fns.c (secure_hash): Fix pointer signedness issue.
10401 * intervals.c (static_offset_intervals): New function.
10402 (offset_intervals): Use it.
10404 2011-06-21 Leo Liu <sdl.web@gmail.com>
10407 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10410 * fns.c (secure_hash): Rename from crypto_hash_function and change
10411 the first arg to accept symbols.
10412 (Fsecure_hash): New primitive.
10413 (syms_of_fns): New symbols.
10415 2011-06-20 Deniz Dogan <deniz@dogan.se>
10417 * process.c (Fset_process_buffer): Clarify return value in
10420 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10422 * dispnew.c (add_window_display_history): Use BVAR.
10424 * xdisp.c (debug_method_add): Use BVAR.
10425 (check_window_end, dump_glyph_matrix, dump_glyph)
10426 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10428 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10431 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10432 check till after the cache is created in init_frame_faces.
10434 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10436 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10438 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10440 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10441 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10442 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10444 Improve buffer-overflow checking (Bug#8873).
10445 * fileio.c (Finsert_file_contents):
10446 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10447 Remove the old (too-loose) buffer overflow checks.
10448 They weren't needed, since make_gap checks for buffer overflow.
10449 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10450 The old code merely checked for Emacs fixnum overflow, and relied
10451 on undefined (wraparound) behavior. The new code avoids undefined
10452 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10454 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10455 Tune. Don't use wider integers than needed. Don't use alloca.
10456 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10458 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10460 * insdel.c, lisp.h (buffer_overflow): New function.
10461 (insert_from_buffer_1, replace_range, replace_range_2):
10462 * insdel.c (make_gap_larger):
10463 * editfns.c (Finsert_char):
10464 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10466 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10468 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10470 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10472 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10473 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10475 * fileio.c: Don't assume EMACS_INT fits in off_t.
10476 (emacs_lseek): New static function.
10477 (Finsert_file_contents, Fwrite_region): Use it.
10478 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10480 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10482 * fns.c: Don't overflow int when computing a list length.
10483 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10484 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10485 truncation on 64-bit hosts. Check for QUIT every
10486 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10487 faster and is responsive enough.
10488 (Flength): Report an error instead of overflowing an integer.
10489 (Fsafe_length): Return a float if the value is not representable
10490 as a fixnum. This shouldn't happen except in contrived situations.
10491 (Fnthcdr, Fsort): Don't assume list length fits in int.
10492 (Fcopy_sequence): Don't assume vector length fits in int.
10494 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10495 (header_size, word_size): New constants.
10496 (allocate_vectorlike): Don't check size overflow here.
10497 (allocate_vector): Check it here instead, since this is the only
10498 caller of allocate_vectorlike that could cause overflow.
10499 Check that the new vector's length is representable as a fixnum.
10501 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10502 The previous code was bogus. For example, next_almost_prime (32)
10503 returned 39, which is undesirable as it is a multiple of 3; and
10504 next_almost_prime (24) returned 25, which is a multiple of 5 so
10505 why was the code bothering to check for multiples of 7?
10507 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10509 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10511 Variadic C functions now count arguments with ptrdiff_t.
10512 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10513 Back then I didn't know that the Emacs coding style prefers signed int.
10514 Also, in the meantime I found a few more instances where arguments
10515 were being counted with int, which may truncate counts on 64-bit
10516 machines, or EMACS_INT, which may be unnecessarily wide.
10517 * lisp.h (struct Lisp_Subr.function.aMANY)
10518 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10519 Arg counts are now ptrdiff_t, not size_t.
10520 All variadic functions and their callers changed accordingly.
10521 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10522 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10523 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10524 * callint.c (Fcall_interactively): Check arg count for overflow,
10525 to avoid potential buffer overrun. Use signed char, not 'int',
10526 for 'varies' array, so that we needn't bother to check its size
10527 calculation for overflow.
10528 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10529 * eval.c (apply_lambda):
10530 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10531 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10532 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10534 * callint.c (Fcall_interactively): Don't use index var as event count.
10536 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10537 * mem-limits.h (SIZE): Remove; no longer used.
10539 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10541 Remove unnecessary casts.
10542 * xterm.c (x_term_init):
10543 * xfns.c (x_set_border_pixel):
10544 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10545 These aren't needed now that we assume ANSI C.
10547 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10548 It's more likely to cause problems (due to unsigned overflow)
10551 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10553 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10555 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10557 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10559 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10561 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10563 GLYPH_CODE_FACE returns EMACS_INT, not int.
10564 * dispextern.h (merge_faces):
10565 * xfaces.c (merge_faces):
10566 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10567 Don't assume EMACS_INT fits in int.
10569 * character.h (CHAR_VALID_P): Remove unused parameter.
10570 * fontset.c, lisp.h, xdisp.c: All uses changed.
10572 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10574 * fns.c (concat): Minor tuning based on overflow analysis.
10575 This doesn't fix any bugs. Use int to hold character, instead
10576 of constantly refetching from Emacs object. Use XFASTINT, not
10577 XINT, for value known to be a character. Don't bother comparing
10578 a single byte to 0400, as it's always less.
10580 * floatfns.c (Fexpt):
10581 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10583 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10586 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10588 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10589 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10590 incorrectly succeed when S was a string, because 4294967386 was
10591 truncated before it was used.
10593 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10594 Otherwise, an out-of-range integer could cause undefined behavior
10597 * composite.c: Use int, not EMACS_INT, for characters.
10598 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10599 EMACS_INT, for values that are known to be in character range.
10600 This doesn't fix any bugs but is the usual style inside Emacs and
10601 may generate better code on 32-bit machines.
10603 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10604 This is for reasons similar to the recent CHAR_STRING fix.
10605 * charset.c (Fencode_char): Check that character arg is actually
10606 a character. Pass an int to ENCODE_CHAR.
10607 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10608 wider than 'int', as a compile-time check to prevent future regressions
10611 * character.c (char_string): Remove unnecessary casts.
10613 Make sure a 64-bit char is never passed to CHAR_STRING.
10614 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10615 by silently ignoring the top 32 bits, allowing some values
10616 that were far too large to be valid characters.
10617 * character.h: Include <verify.h>.
10618 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10619 arguments are no wider than unsigned, as a compile-time check
10620 to prevent future regressions in this area.
10622 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10623 (Fsubst_char_in_region):
10625 * xdisp.c (decode_mode_spec_coding):
10626 Adjust to CHAR_STRING's new requirement.
10627 * editfns.c (Finsert_char, Fsubst_char_in_region):
10628 * fns.c (concat): Check that character args are actually
10629 characters. Without this test, these functions did the wrong
10630 thing with wildly out-of-range values on 64-bit hosts.
10632 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10633 These casts should not be needed on 32-bit hosts, either.
10634 * keyboard.c (read_char):
10635 * lread.c (Fload): Remove casts to unsigned.
10637 * lisp.h (UNSIGNED_CMP): New macro.
10638 This fixes comparison bugs on 64-bit hosts.
10639 (ASCII_CHAR_P): Use it.
10640 * casefiddle.c (casify_object):
10641 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10642 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10643 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10644 * dispextern.h (FACE_FROM_ID):
10645 * keyboard.c (read_char): Use UNSIGNED_CMP.
10647 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10648 not to EMACS_INT, to avoid GCC warning.
10650 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10652 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10653 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10654 isn't needed on 32-bit machines.
10656 * buffer.c (Fgenerate_new_buffer_name):
10657 Use EMACS_INT for count, not int.
10658 (advance_to_char_boundary): Return EMACS_INT, not int.
10660 * data.c (Qcompiled_function): Now static.
10662 * window.c (window_body_lines): Now static.
10664 * image.c (gif_load): Rename local to avoid shadowing.
10666 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10667 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10668 * alloc.c (make_save_value): Integer argument is now of type
10669 ptrdiff_t, not int.
10670 (mark_object): Use ptrdiff_t, not int.
10671 * lisp.h (pD): New macro.
10672 * print.c (print_object): Use it.
10674 * alloc.c: Use EMACS_INT, not int, to count objects.
10675 (total_conses, total_markers, total_symbols, total_vector_size)
10676 (total_free_conses, total_free_markers, total_free_symbols)
10677 (total_free_floats, total_floats, total_free_intervals)
10678 (total_intervals, total_strings, total_free_strings):
10679 Now EMACS_INT, not int. All uses changed.
10680 (Fgarbage_collect): Compute overall total using a double, so that
10681 integer overflow is less likely to be a problem. Check for overflow
10682 when converting back to an integer.
10683 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10684 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10685 These were 'int' variables that could overflow on 64-bit hosts;
10686 they were never used, so remove them instead of repairing them.
10687 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10688 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10689 Previously, this ceilinged at INT_MAX, but that doesn't work on
10691 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10693 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10694 (allocate_vectorlike): Check for ptrdiff_t overflow.
10695 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10696 when a (possibly-narrower) signed value would do just as well.
10697 We prefer using signed arithmetic, to avoid comparison confusion.
10699 * alloc.c: Catch some string size overflows that we were missing.
10700 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10701 for convenience in STRING_BYTES_MAX.
10702 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10703 The definition here is exact; the one in lisp.h was approximate.
10704 (allocate_string_data): Check for string overflow. This catches
10705 some instances we weren't catching before. Also, it catches
10706 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10707 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10708 and ptrdiff_t and EMACS_INT are both 64 bits.
10710 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10711 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10712 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10714 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10716 * alloc.c (Fmake_string): Check for out-of-range init.
10718 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10720 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10722 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10724 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10725 xg_get_default_scrollbar_width.
10727 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10728 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10729 (style_changed_cb): Call update_theme_scrollbar_width and call
10730 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10731 all frames (Bug#8505).
10732 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10733 Call gtk_window_set_resizable if HAVE_GTK3.
10734 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10735 and height if HAVE_GTK3 (Bug#8505).
10736 (scroll_bar_width_for_theme): New variable.
10737 (update_theme_scrollbar_width): New function.
10738 (xg_get_default_scrollbar_width): Move code to
10739 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10740 (xg_initialize): Call update_theme_scrollbar_width.
10742 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10744 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10746 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10748 * frame.c (make_frame): Call other_buffer_safely instead of
10751 * window.c (temp_output_buffer_show): Call display_buffer with
10752 second argument Vtemp_buffer_show_specifiers and reset latter
10753 immediately after the call.
10754 (Vtemp_buffer_show_specifiers): New variable.
10755 (auto_window_vscroll_p, next_screen_context_lines)
10756 (Vscroll_preserve_screen_position): Remove leading asterisks from
10759 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10761 Fix minor problems found by GCC 4.6.0 static checking.
10762 * buffer.c (Qclone_number): Remove for now, as it's unused.
10763 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10764 (record_buffer): Remove unused local.
10765 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10766 (set_frame_buffer_list): Remove; unused.
10767 * frame.h (other_visible_frames): Remove decl.
10768 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10769 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10770 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10772 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10773 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10774 Define only if HAVE_GPM.
10775 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10776 (update_hints_inhibit): Remove; never set. All uses removed.
10777 * widgetprv.h (emacsFrameClassRec): Remove decl.
10778 * window.c (delete_deletable_window): Now returns void, since it
10779 wasn't returning anything.
10780 (compare_window_configurations): Remove unused locals.
10781 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10782 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10783 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10784 the same widths as pointers. This follows up on the 2011-05-06 patch.
10785 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10786 * xterm.h: Likewise.

10792 (LISP_H): Add lib/intprops.h.
10794 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10796 * image.c (gif_load): Add animation frame delay to the metadata.
10797 (syms_of_image): Use DEFSYM. New symbol `delay'.
10799 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10801 * window.c (delete_deletable_window): Re-add.
10802 (Fset_window_configuration): Rewrite to handle dead buffers and
10803 consequently deletable windows.
10804 (window_tree, Fwindow_tree): Remove. Supply functionality in
10806 (compare_window_configurations): Simplify code.
10808 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10810 * image.c (imagemagick_load_image): Fix type mismatch.
10811 (Fimagemagick_types): Likewise.
10813 * window.h (replace_buffer_in_windows): Declare.
10815 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10817 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10818 Qclone_number. Remove external declaration of Qdelete_window.
10819 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10821 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10822 Run Qbuffer_list_update_hook if allowed.
10823 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10824 buffer list implementation.
10825 (other_buffer_safely): New function.
10826 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10827 calls to replace_buffer_in_windows and
10828 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10830 (record_buffer): Inhibit quitting and rewrite using quittable
10831 functions. Run Qbuffer_list_update_hook if allowed.
10832 (Frecord_buffer, Funrecord_buffer): New functions.
10833 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10834 Move switch-to-buffer to window.el.
10835 (bury-buffer): Move to window.el.
10836 (Vbuffer_list_update_hook): New variable.
10838 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10841 * window.h (resize_frame_windows): Move up in code.
10842 (Fwindow_frame): Remove EXFUN.
10843 (replace_buffer_in_all_windows): Remove prototype.
10844 (replace_buffer_in_windows_safely): Add prototype.
10846 * window.c: Declare Qdelete_window static again. Move down
10847 declaration of select_count.
10848 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10849 (Fother_window): Move to window.el.
10850 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10851 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
10852 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
10854 (replace_buffer_in_windows): Implement by calling
10855 Qreplace_buffer_in_windows.
10856 (replace_buffer_in_all_windows): Remove with some functionality
10857 moved into replace_buffer_in_windows_safely.
10858 (replace_buffer_in_windows_safely): New function.
10859 (select_window_norecord, select_frame_norecord): Move in front
10860 of run_window_configuration_change_hook. Remove now obsolete
10862 (Fset_window_buffer): Rewrite doc-string.
10863 Call Qrecord_window_buffer.
10864 (keys_of_window): Move binding for other-window to window.el.
10866 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10868 * dispextern.h (struct image): Replace data member, whose int_val
10869 and ptr_val fields were not used by anything, with a single
10872 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
10873 (gif_clear_image, gif_load, imagemagick_load_image)

11352 * gnutls.c: Use Emacs's memory allocators.
11353 Without this change, the gnutls library would invoke malloc etc.
11354 directly, which causes problems on non-SYNC_INPUT hosts, and which
11355 runs afoul of improving memory_full behavior. (Bug#8761)
11356 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11357 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11358 xfree instead of the default malloc, realloc, free.
11359 (Fgnutls_boot): No need to check for memory allocation failure,
11360 since xmalloc does that for us.
11362 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11363 * category.c (hash_get_category_set):
11364 * ccl.c (ccl_driver):
11365 * charset.c (Fdefine_charset_internal):
11366 * charset.h (struct charset.hash_index):
11367 * composite.c (get_composition_id, gstring_lookup_cache)
11368 (composition_gstring_put_cache):
11369 * composite.h (struct composition.hash_index):
11370 * dispextern.h (struct image.hash):
11371 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11372 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

11376 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11377 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11378 * image.c (make_image, search_image_cache, lookup_image)
11379 (xpm_put_color_table_h):
11380 * lisp.h (struct Lisp_Hash_Table):
11381 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11382 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11383 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11384 * alloc.c (allocate_vectorlike):
11385 Check for overflow in vector size calculations.
11386 * ccl.c (ccl_driver):
11387 Check for overflow when converting EMACS_INT to int.
11388 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11389 need to be updated by these changes.
11390 * fns.c (make_hash_table, maybe_resize_hash_table):
11391 Check for integer overflow with large hash tables.
11392 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11393 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11394 (SXHASH_REDUCE): New macro.
11395 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11396 Use it instead of discarding useful hash info with large hash values.
11397 (sxhash_float): New function.
11398 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11399 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11400 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11401 Rewrite to use FIXNUM_BITS, as this simplifies things.
11402 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11403 Adjust signatures to match updated version of code.
11404 (consing_since_gc): Now EMACS_INT, since a single hash table can
11405 use more than INT_MAX bytes.
11407 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11409 Make it possible to build with GCC-4.6+ -O2 -flto.
11411 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11413 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11415 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11416 Call minibuffer-inactive-mode.
11418 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11420 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11421 Update dependencies.
11423 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11425 * data.c (init_data): Remove code for UTS, this system is not
11428 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11430 Don't force ./temacs to start in terminal mode.
11432 * frame.c (make_initial_frame): Initialize faces in all cases, not
11433 only when CANNOT_DUMP is defined.
11434 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11436 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11438 * dispnew.c (add_window_display_history): Use const for the string
11439 pointer. Remove declaration, not needed.
11441 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11443 Use 'inline', not 'INLINE'.
11444 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11445 * alloc.c, fontset.c (INLINE): Remove.
11446 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11447 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11448 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11449 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11450 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11452 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11454 Make it possible to run ./temacs.
11456 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11457 syms_of_callproc does the same thing. Remove test for
11458 "initialized", do it in the caller.
11459 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11461 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11463 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11464 (read_minibuf): Use get_minibuffer.
11465 (syms_of_minibuf): Use DEFSYM.
11466 (Qmetadata): New var.
11467 * data.c (Qbuffer): Don't make it static.
11468 (syms_of_data): Use DEFSYM.
11470 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11472 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11473 (CCL_CODE_MIN): New macro.
11475 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11477 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11479 * eval.c (Qdebug): Now static.
11480 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11481 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11482 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11484 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11486 * image.c: Various fixes to ImageMagick code comments.
11487 (Fimagemagick_types): Doc fix.
11489 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11491 Minor fixes prompted by GCC 4.6.0 warnings.
11493 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11495 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11496 (x_clipboard_manager_save_all): Move extern decl to ...
11497 * xterm.h: ... here, so that it can be checked for consistency.
11499 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11501 * xselect.c (x_clipboard_manager_save_frame)
11502 (x_clipboard_manager_save_all): New functions.
11503 (Fx_clipboard_manager_save): Lisp function deleted.
11505 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11506 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11508 * xterm.h: Update prototype.
11510 2011-05-28 William Xu <william.xwl@gmail.com>
11512 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11513 exiting (Bug#8239).
11515 2011-05-28 Jim Meyering <meyering@redhat.com>
11517 Avoid a sign-extension bug in crypto_hash_function.
11518 * fns.c (to_uchar): Define.
11519 (crypto_hash_function): Use it to convert some newly-signed
11520 variables to unsigned, to avoid sign-extension bugs. For example,
11521 without this change, (md5 "truc") would evaluate to
11522 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11523 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11524 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11526 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11528 Integer overflow fixes.
11530 * dbusbind.c: Serial number integer overflow fixes.
11531 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11532 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11533 to hold a serial number that is too large for a fixnum.
11534 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11535 Check for serial numbers out of range. Decode any serial number
11536 that was so large that it became a float. (Bug#8722)
11538 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11539 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11540 Use XFASTINT rather than XUINT when numbers are nonnegative.
11541 (xd_append_arg, Fdbus_method_return_internal):
11542 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11543 arguments, check that Lisp number is nonnegative, rather than
11544 silently wrapping negative numbers around. (Bug#8722)
11545 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11548 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11550 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11552 ccl: Add integer overflow checks.
11553 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11554 (IN_INT_RANGE): New macros.
11555 (ccl_driver): Use them to check for integer overflow when
11556 decoding a CCL program. Many of the new checks are whether XINT (x)
11557 fits in int; it doesn't always, on 64-bit hosts. The new version
11558 doesn't catch all possible integer overflows, but it's an
11559 improvement. (Bug#8719)
11561 * alloc.c (make_event_array): Use XINT, not XUINT.
11562 There's no need for unsigned here.
11564 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11565 This follows up to the 2011-05-06 change that substituted uintptr_t
11566 for EMACS_INT. This case wasn't caught back then.
11568 Rework Fformat to avoid integer overflow issues.
11569 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11570 now (part of C89). Include <verify.h>.
11571 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11572 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11573 (Fformat): Avoid the prepass trying to compute sizes; it was only
11574 approximate and thus did not catch overflow reliably. Instead, walk
11575 through the format just once, formatting and computing sizes as we go,
11576 checking for integer overflow at every step, and allocating a larger
11577 buffer as needed. Keep track separately whether the format is
11578 multibyte. Keep only the most-recently calculated precision, rather
11579 than them all. Record whether each argument has been converted to
11580 string. Use EMACS_INT, not int, for byte and char and arg counts.
11581 Support field widths and precisions larger than INT_MAX. Avoid
11582 sprintf's undefined behavior with conversion specifications such as %#d
11583 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11584 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11585 formatting out-of-range floating point numbers with int
11586 formats. (Bug#8668)
11588 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11590 * data.c: Avoid integer truncation in expressions involving floats.
11591 * data.c: Include <intprops.h>.
11592 (arith_driver): When there's an integer overflow in an expression
11593 involving floating point, convert the integers to floating point
11594 so that the resulting value does not suffer from catastrophic
11595 integer truncation. For example, on a 64-bit host (* 4
11596 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11597 Do not rely on undefined behavior after integer overflow.
11599 merge count_size_as_multibyte, parse_str_to_multibyte
11600 * character.c, character.h (count_size_as_multibyte):
11601 Rename from parse_str_to_multibyte; all uses changed.
11602 Check for integer overflow.
11603 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11604 since it's now a duplicate of the other. This is more of
11605 a character than a buffer op, so better that it's in character.c.
11606 * fns.c, print.c: Adjust to above changes.
11608 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11610 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11612 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11614 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11615 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11616 (x_clipboard_manager_save): Now static.
11617 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11619 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11620 (crypto_hash_function): Now static.
11621 Fix pointer signedness problems. Avoid unnecessary initializations.
11623 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11625 * termhooks.h (Vselection_alist): Make it terminal-local.
11627 * terminal.c (create_terminal): Initialize it.
11629 * xselect.c: Support for clipboard managers.
11630 (Vselection_alist): Move to termhooks.h as terminal-local var.
11631 (LOCAL_SELECTION): New macro.
11632 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11633 (symbol_to_x_atom): Remove gratuitous arg.
11634 (x_handle_selection_request, lisp_data_to_selection_data)
11635 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11636 (x_own_selection, x_get_local_selection, x_convert_selection):
11637 New arg, specifying work frame. Use terminal-local Vselection_alist.
11638 (some_frame_on_display): Delete unused function.
11639 (Fx_own_selection_internal, Fx_get_selection_internal)
11640 (Fx_disown_selection_internal, Fx_selection_owner_p)
11641 (Fx_selection_exists_p): New optional frame arg.
11642 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11643 (x_handle_selection_clear): Don't treat other terminals with the
11644 same keyboard specially. Use the terminal-local Vselection_alist.
11645 (x_clear_frame_selections): Use Frun_hook_with_args.
11647 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11649 * xterm.h: Add support for those atoms.
11651 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11653 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11654 (converted_selections, conversion_fail_tag): New global variables.
11655 (x_selection_request_lisp_error): Free the above.
11656 (x_get_local_selection): Remove unnecessary code.
11657 (x_reply_selection_request): Args changed; handle arbitrary array
11658 of converted selections stored in converted_selections.
11659 Separate the XChangeProperty and SelectionNotify steps.
11660 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11661 (x_convert_selection): New function.
11662 (x_handle_selection_event): Simplify.
11663 (x_get_foreign_selection): Don't ignore incoming requests while
11664 waiting for an answer; this will fail when we implement
11665 SAVE_TARGETS, and seems unnecessary anyway.
11666 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11667 (Vx_sent_selection_functions): Doc fix.
11669 2011-05-26 Leo Liu <sdl.web@gmail.com>
11671 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11673 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11675 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11677 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11678 for fringe update if it has periodic bitmap.
11679 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11680 and fringe_bitmap_periodic_p.
11682 * fringe.c (get_fringe_bitmap_data): New function.
11683 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11684 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11685 row. Mark glyph row for fringe update if periodicity changed.
11687 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11688 for fringe update unless it has periodic bitmap.
11690 2011-05-25 Kenichi Handa <handa@m17n.org>

11708 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11709 Remove macros that are defined and never used.
11710 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11712 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11714 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11715 (Fx_get_selection_internal): Minor cleanup.
11716 (Fx_own_selection_internal): Rename arguments for consistency with
11719 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

11741 report_file_error introduced by the change from 2011-05-07.
11743 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11745 * systime.h (Time): Define only if emacs is defined.
11746 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11747 where the include path doesn't have X11/X.h by default. See
11748 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11750 2011-05-20 Kenichi Handa <handa@m17n.org>
11752 * composite.c (find_automatic_composition): Fix previous change.
11754 2011-05-20 Glenn Morris <rgm@gnu.org>

11765 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11766 (lisp): Set the order to that of loadup.el.
11767 (shortlisp): Make it a copy of $lisp.
11768 (SOME_MACHINE_LISP): Remove.
11769 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.

11772 2011-05-18 Kenichi Handa <handa@m17n.org>
11774 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11775 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11776 (find_automatic_composition): Mostly rewrite for efficiency.
11778 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11780 * makefile.w32-in: Update dependencies.
11782 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11784 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11785 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11787 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11789 Fix some integer overflow issues, such as string length overflow.
11791 * insdel.c (count_size_as_multibyte): Check for string overflow.
11793 * character.c (lisp_string_width): Check for string overflow.
11794 Use EMACS_INT, not int, for string indexes and lengths; in
11795 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11796 the resulting string length overflows an EMACS_INT; instead,
11797 report a string overflow if no precision given. When checking for
11798 precision exhaustion, use a check that cannot possibly have
11799 integer overflow. (Bug#8675)
11800 * character.h (lisp_string_width): Adjust to new signature.
11802 * alloc.c (string_overflow): New function.
11803 (Fmake_string): Use it. This doesn't change behavior, but saves
11804 a few bytes and will simplify future changes.
11805 * character.c (string_escape_byte8): Likewise.
11806 * lisp.h (string_overflow): New decl.
11808 Fixups, following up to the user-interface timestamp change.
11809 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11810 for UI timestamps, instead of unsigned long.
11811 * msdos.c (mouse_get_pos): Likewise.
11812 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11813 * w32gui.h (Time): Define by including "systime.h" rather than by
11814 declaring it ourselves. (Bug#8664)
11816 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11817 * image.c (clear_image_cache): Likewise.
11819 * term.c (term_mouse_position): Don't assume time_t wraparound.
11821 Be more systematic about user-interface timestamps.
11822 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11823 and sometimes 'EMACS_UINT', to represent these timestamps.
11824 This change causes it to use 'Time' uniformly, as that's what X uses.
11825 This makes the code easier to follow, and makes it easier to catch
11826 integer overflow bugs such as Bug#8664.
11827 * frame.c (Fmouse_position, Fmouse_pixel_position):
11828 Use Time, not unsigned long, for user-interface timestamps.
11829 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11830 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11831 * keyboard.h (last_event_timestamp): Likewise.
11832 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11833 * menu.h (xmenu_show): Likewise.
11834 * term.c (term_mouse_position): Likewise.
11835 * termhooks.h (struct input_event.timestamp): Likewise.
11836 (struct terminal.mouse_position_hook): Likewise.
11837 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11838 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11839 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11840 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11841 what it was before.
11842 * menu.h, termhooks.h: Include "systime.h", for Time.
11844 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11845 Don't assume that the difference between two unsigned long values
11846 can fit into an integer. At this point, we know button_down_time
11847 <= event->timestamp, so the difference must be nonnegative, so
11848 there's no need to cast the result if double-click-time is
11849 nonnegative, as it should be; check that it's nonnegative, just in
11850 case. This bug is triggered when events are more than 2**31 ms
11851 apart (about 25 days). (Bug#8664)
11853 * xselect.c (last_event_timestamp): Remove duplicate decl.
11854 (x_own_selection): Remove needless cast to unsigned long.
11856 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11857 that always fit in int. Use a sentinel instead of a counter, to
11858 avoid a temp and to allay GCC's concerns about possible int overflow.
11859 * frame.h (struct frame): Use int for menu_bar_items_used
11860 instead of EMACS_INT, since it always fits in int.
11862 * menu.c (grow_menu_items): Check for int overflow.
11864 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11866 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11867 Before, the code was not consistent. These values cannot exceed
11868 2**31 - 1 so there's no need to make them unsigned.
11869 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11870 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11871 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11873 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11875 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11876 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11877 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11878 presumably because the widths might not match.
11880 * window.c (size_window): Avoid needless test at loop start.
11882 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11884 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11886 2011-05-12 Drew Adams <drew.adams@oracle.com>
11888 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11890 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11892 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11893 `width' to `bar_area_x' and `bar_area_width', respectively.
11894 (x_scroll_run): Take account of fringe background extension.
11896 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11897 Rename local vars `left' and `width' to `bar_area_x' and
11898 `bar_area_width', respectively.
11899 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11900 background extension.
11902 2011-05-10 Jim Meyering <meyering@redhat.com>
11904 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11906 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11908 * image.c (Finit_image_library): Return t for built-in image types,
11909 like pbm and xbm. (Bug#8640)
11911 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11913 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11915 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11917 * w32console.c (Fset_screen_color): Doc fix.
11918 (Fget_screen_color): New function.
11919 (syms_of_ntterm): Defsubr it.
11921 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11922 unlink the temporary file if Fcall_process didn't create it in the
11924 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11925 child process will be redirected to a file specified with `:file'.
11926 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11927 cue to call_process_cleanup not to close that handle.
11929 2011-05-07 Ben Key <bkey76@gmail.com>
11931 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11932 one of two shell specific rules, either bootstrap-temacs-CMD or
11933 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11934 to the previous implementation of the bootstrap-temacs rule.
11935 The bootstrap-temacs-CMD rule is similar to the previous
11936 implementation of the bootstrap-temacs rule except that it
11937 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11940 These changes, along with some changes to nt/configure.bat,
11941 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11942 earlier fix to add support for --cflags and --ldflags options
11943 that include quotes so that it works whether make uses cmd or
11946 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11948 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11949 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11951 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11952 a string. Handle both cases.
11953 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11954 (Fdbus_register_method): Use Qinvalid_function.
11956 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11958 * makefile.w32-in: Update dependencies.
11959 (LISP_H): Add inttypes.h and stdin.h.
11960 (PROCESS_H): Add unistd.h.
11962 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11964 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11965 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11967 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11969 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11971 * term.c (vfatal): Remove stray call to va_end.
11972 It's not needed and the C Standard doesn't allow it here anyway.
11974 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11975 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11977 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11980 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11982 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11984 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11986 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11988 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11990 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11991 * charset.c (Fdefine_charset_internal): Don't initialize
11992 charset.code_space[15]. The value was garbage, on hosts with
11993 32-bit int (Bug#8600).
11995 * lread.c (read_integer): Be more consistent with string-to-number.
11996 Use string_to_number to do the actual conversion; this avoids
11997 rounding errors and fixes some other screwups. Without this fix,
11998 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11999 (digit_to_number): Move earlier, for benefit of read_integer.
12000 Return -1 if the digit is out of range for the base, -2 if it is
12001 not a digit in any supported base. (Bug#8602)
12003 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12005 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12006 to match comment at start of function. This also removes a
12007 GCC warning about overflow in a 32+64-bit port.
12009 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12011 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12012 Reported by Stefan Monnier in
12013 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12014 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12015 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12017 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12018 (EMACS_UINTPTR): Likewise, with uintptr_t.
12020 * lisp.h: Prefer 64-bit EMACS_INT if available.
12021 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12022 on 32-bit hosts that have 64-bit int, so that they can access
12024 However, temporarily disable this change unless the temporary
12025 symbol WIDE_EMACS_INT is defined.
12027 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12029 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12030 This removes an assumption that EMACS_INT and long are the same
12031 width as pointers. The assumption is true for Emacs porting targets
12032 now, but we want to make other targets possible.
12033 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12034 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12035 In the rest of the code, change types of integers that hold casted
12036 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12037 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12038 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12039 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12040 No need to cast type when ORing.
12041 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12042 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12043 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12044 assume EMACS_INT is the same width as char *.
12045 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12046 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12047 Remove no-longer-needed casts.
12048 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12049 (xg_tool_bar_help_callback, xg_make_tool_item):
12050 Use EMACS_INTPTR to hold an integer
12051 that will be cast to void *; this can avoid a GCC warning
12052 if EMACS_INT is not the same width as void *.
12053 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12054 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12055 (current_message_1, set_message_1):
12056 Use a local to convert to proper width without a cast.
12057 * xmenu.c (dialog_selection_callback): Likewise.
12059 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12060 Also, don't assume VALBITS / RAND_BITS is less than 5,
12061 and don't rely on undefined behavior when shifting a 1 left into
12063 * lisp.h (get_random): Change signature to match.
12065 * lread.c (hash_string): Use size_t, not int, for hash computation.
12066 Normally we prefer signed values; but hashing is special, because
12067 it's better to use unsigned division on hash table sizes so that
12068 the remainder is nonnegative. Also, size_t is the natural width
12069 for hashing into memory. The previous code used 'int', which doesn't
12070 retain enough info to hash well into very large tables.
12071 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12073 * dbusbind.c: Don't possibly lose pointer info when converting.
12074 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12075 Use XPNTR rather than XHASH, so that the high-order bits of
12076 the pointer aren't lost when converting through void *.
12078 * eval.c (Fautoload): Don't double-shift a pointer.
12080 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12082 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12084 * gnutls.c (DEF_GNUTLS_FN):
12085 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12087 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12089 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12092 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12094 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12095 New version that can reserve upto 2GB of heap space.
12097 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12099 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12101 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12103 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12104 `gnutls_certificate_set_x509_key_file'.
12106 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12108 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12109 Update dependencies.
12111 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12113 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12114 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12115 Remove unused parameter `fildes'.
12116 * process.c (read_process_output, send_process): Don't pass it.
12118 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12120 Fix previous change: the library cache is defined in w32.c.
12121 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12122 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12124 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12126 Implement dynamic loading of GnuTLS on Windows.
12128 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12129 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12130 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12133 * gnutls.c (Qgnutls_dll): Define.
12134 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12135 (gnutls_*): Declare function pointers.
12136 (init_gnutls_functions): New function to initialize function pointers.
12137 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12138 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12139 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12140 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12141 (emacs_gnutls_write, emacs_gnutls_read)
12142 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12143 (Fgnutls_available_p): New function.
12144 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12145 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12146 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12148 * image.c: Include w32.h.
12149 (Vimage_type_cache): Delete.
12150 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12151 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12152 (w32_delayed_load): Move to w32.c.
12154 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12156 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12157 (w32_delayed_load): Move from image.c. When loading a library, record
12158 its filename in the :loaded-from property of the library id.
12159 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12160 Initialize and staticpro them.
12161 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12163 * process.c: Include lisp.h before w32.h, not after.
12164 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12165 instead of gnutls_record_check_pending.
12167 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12169 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12171 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12172 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12175 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12177 * xterm.c (x_set_frame_alpha): Do not set property on anything
12178 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12180 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12182 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12184 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12186 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12187 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12193 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12194 (Qgnutls_bootprop_callbacks_verify): Make static.
12196 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>

12202 Move after wait_for_termination_1.
12204 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12206 * sysdep.c (interruptible_wait_for_termination): New function
12207 which is like wait_for_termination, but allows keyboard
12210 * callproc.c (Fcall_process): Add (:file "file") as an option for
12212 (Fcall_process_region): Ditto.
12214 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12216 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12217 rather than `XVECTOR (FOO)->size'.
12219 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12220 inttypes.h, as a gnulib replacement is used if it not available in
12223 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12225 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12226 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12227 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12229 * coding.c (coding_alloc_by_realloc): Error out if destination
12230 will grow beyond MOST_POSITIVE_FIXNUM.
12231 (decode_coding_emacs_mule): Abort if there isn't enough place in
12232 charbuf for the composition carryover bytes. Reserve an extra
12233 space for up to 2 characters produced in a loop.
12234 (decode_coding_iso_2022): Abort if there isn't enough place in
12235 charbuf for the composition carryover bytes.
12237 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12239 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12240 aborting when %lld or %lll format is passed.
12241 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12242 %llo or %llx format is passed. (Bug#8545)
12244 * window.c (window_scroll_line_based): Use a marker instead of
12245 simple variables to record original value of point. (Bug#7952)
12247 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12248 produced by %s or %c overflows available buffer space. (Bug#8545)
12250 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12252 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12253 (SIZE_MAX): Move defn after all includes, as they might #define it.
12255 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12257 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12259 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12261 * keyboard.c (Qdelayed_warnings_hook): Define.
12262 (command_loop_1): Run `delayed-warnings-hook'
12263 if Vdelayed_warnings_list is non-nil.
12264 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12265 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12267 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12269 * doprnt.c (doprnt): Don't return value smaller than the buffer
12270 size if the message was truncated. (Bug#8545).
12272 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12274 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12275 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12277 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12279 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12281 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12283 * makefile.w32-in: Update dependencies.
12285 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12287 Improve `doprnt' and its usage. (Bug#8545)
12288 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12289 `format_end'. Remove support for %l as a conversion specifier.
12290 Don't use xrealloc. Improve diagnostics when the %l size modifier
12291 is used. Update the commentary.
12293 * eval.c (verror): Simplify calculation of size_t.
12295 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12298 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12300 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12303 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12305 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12306 This makes this file independent of the recent pseudovector change.
12308 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12310 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12312 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12313 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12314 Remove unused local.
12315 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12317 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12318 GCC 4.6.0 optimizes based on type-based alias analysis.
12319 For example, if b is of type struct buffer * and v of type struct
12320 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12321 != &v->size, and therefore "v->size = 1; b->size = 2; return
12322 v->size;" must therefore return 1. This assumption is incorrect
12323 for Emacs, since it type-puns struct Lisp_Vector * with many other
12324 types. To fix this problem, this patch adds a new type struct
12325 vectorlike_header that documents the constraints on layout of vectors
12326 and pseudovectors, and helps optimizing compilers not get fooled
12327 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12328 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12329 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12331 (XSETPVECTYPE): Rewrite in terms of new macro.
12332 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12333 This is a bit clearer, and further avoids the possibility of
12334 undesirable aliasing.
12335 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12336 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12337 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12338 since Lisp_Subr is a special case (no "next" field).
12339 (ASIZE): Now uses header.size rather than size.
12340 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12341 to avoid the hassle of writing XVECTOR (foo)->header.size.
12342 (struct vectorlike_header): New type.
12343 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12344 object, to help avoid aliasing.
12345 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12346 (SUBRP): Likewise, since Lisp_Subr is a special case.
12347 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12348 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12349 (struct Lisp_Hash_Table): Combine first two members into a single
12350 struct vectorlike_header member. All uses of "size" and "next" members
12351 changed to be "header.size" and "header.next".
12352 * buffer.h (struct buffer): Likewise.
12353 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12354 * frame.h (struct frame): Likewise.
12355 * process.h (struct Lisp_Process): Likewise.
12356 * termhooks.h (struct terminal): Likewise.
12357 * window.c (struct save_window_data, struct saved_window): Likewise.
12358 * window.h (struct window): Likewise.
12359 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12360 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12361 * buffer.c (init_buffer_once): Likewise.
12362 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12364 * process.c (Fformat_network_address): Use local var for size,
12367 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12369 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12370 * data.c (atof): Remove decl; no longer used or needed.
12371 (digit_to_number): Move to lread.c.
12372 (Fstring_to_number): Use new string_to_number function, to be
12373 consistent with how the Lisp reader treats infinities and NaNs.
12374 Do not assume that floating-point numbers represent EMACS_INT
12375 without losing information; this is not true on most 64-bit hosts.
12376 Avoid double-rounding errors, by insisting on integers when
12377 parsing non-base-10 numbers, as the documentation specifies.
12378 * lisp.h (string_to_number): New decl, replacing ...
12379 (isfloat_string): Remove.
12380 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12381 (read1): Do not accept +. and -. as integers; this
12382 appears to have been a coding error. Similarly, do not accept
12383 strings like +-1e0 as floating point numbers. Do not report
12384 overflow for integer overflows unless the base is not 10 which
12385 means we have no simple and reliable way to continue.
12386 Break out the floating-point parsing into a new
12387 function string_to_number, so that Fstring_to_number parses
12388 floating point numbers consistently with the Lisp reader.
12389 (digit_to_number): Move here from data.c. Make it static inline.
12390 (E_CHAR, EXP_INT): Remove, replacing with ...
12391 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12392 (string_to_number): New function, replacing isfloat_string.
12393 This function checks for valid syntax and produces the resulting
12394 Lisp float number too. Rework it so that string-to-number
12395 no longer mishandles examples like "1.0e+". Use strtoumax,
12396 so that overflow for non-base-10 numbers is reported only when
12397 there's no portable and simple way to convert to floating point.
12399 * textprop.c (set_text_properties_1): Rewrite for clarity,
12400 and to avoid GCC warning about integer overflow.
12402 * intervals.h (struct interval): Use EMACS_INT for members
12403 where EMACS_UINT might cause problems. See
12404 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12405 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12406 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12408 (offset_intervals): Tell GCC not to worry about length overflow
12409 when negating a negative length.
12411 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12412 (overrun_check_free): Likewise.
12414 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12415 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12418 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12419 (gnutls_make_error): Rename local to avoid shadowing.
12420 (gnutls_emacs_global_deinit): ifdef out; not used.
12421 (Fgnutls_boot): Use const for pointer to readonly storage.
12422 Comment out unused local. Fix pointer signedness problems.
12424 * lread.c (openp): Don't stuff size_t into an 'int'.
12425 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12426 about possible signed overflow.
12428 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12429 (GDK_KEY_g): Don't define if already defined.
12430 (xg_prepare_tooltip): Avoid pointer signedness problem.
12431 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12433 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12434 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12436 * xfns.c (Fx_window_property): Simplify a bit,
12437 to make a bit faster and to avoid GCC 4.6.0 warning.
12438 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12440 * fns.c (internal_equal): Don't assume size_t fits in int.
12442 * alloc.c (compact_small_strings): Tighten assertion a little.
12444 Replace pEd with more-general pI, and fix some printf arg casts.
12445 * lisp.h (pI): New macro, generalizing old pEd macro to other
12446 conversion specifiers. For example, use "...%"pI"d..." rather
12447 than "...%"pEd"...".
12448 (pEd): Remove. All uses replaced with similar uses of pI.
12449 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12450 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12451 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12452 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12453 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12454 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12455 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12457 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12458 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12459 * print.c (safe_debug_print, print_object): Likewise.
12460 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12462 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12463 avoiding the 0 flag, which is not portable.
12464 * process.c (Fmake_network_process): Use pI to avoid cast.
12465 * region-cache.c (pp_cache): Likewise.
12466 * xdisp.c (decode_mode_spec): Likewise.
12467 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12468 behavior on 64-bit hosts with printf arg.
12469 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12470 (x_stop_queuing_selection_requests): Likewise.
12471 (x_get_window_property): Don't truncate byte count to an 'int'
12474 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12475 here, since it parses constructs like leading '-' and spaces,
12476 which are not wanted; and it overflows with large numbers.
12477 Instead, simply match F[0-9]+, which is what is wanted anyway.
12479 * alloc.c: Remove unportable assumptions about struct layout.
12480 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12481 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12482 (allocate_vectorlike, make_pure_vector): Use the new macros,
12483 plus offsetof, to remove unportable assumptions about struct layout.
12484 These assumptions hold on all porting targets that I know of, but
12485 they are not guaranteed, they're easy to remove, and removing them
12486 makes further changes easier.
12488 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12489 This doesn't fix a bug but makes the code clearer.
12490 (string_overrun_cookie): Now const. Use initializers that
12491 don't formally overflow signed char, to avoid warnings.
12492 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12493 can cause Emacs to crash when string overrun checking is enabled.
12494 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12495 multiple of sizeof (EMACS_INT); it need not be, if
12496 alignof(EMACS_INT) < sizeof (EMACS_INT).
12497 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12499 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12506 supposed to be handshaking. (Bug#8556)
12507 Reported by Paul Eggert <eggert@cs.ucla.edu>.

12519 * alloc.c (check_sblock, check_string_bytes)
12520 (check_string_free_list): Convert to standard C.
12522 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12524 * w32.c (emacs_gnutls_push): Fix typo.
12526 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12528 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12529 "cast to pointer from integer of different size".
12531 Improve doprnt and its use in verror. (Bug#8545)
12532 * doprnt.c (doprnt): Document the set of format control sequences
12533 supported by the function. Use SAFE_ALLOCA instead of always
12536 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12537 is one byte too soon. Don't use xrealloc; instead xfree and
12540 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12542 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12545 * gnutls.c: Renamed global_initialized to
12546 gnutls_global_initialized. Added internals for the
12547 :verify-hostname-error, :verify-error, and :verify-flags
12548 parameters of `gnutls-boot' and documented those parameters in the
12549 docstring. Start callback support.
12550 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12551 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12552 on error. Return error code.
12553 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12554 (emacs_gnutls_read): Likewise.
12555 (Fgnutls_boot): Return handshake error code.
12556 (emacs_gnutls_handle_error): New function.
12557 (wsaerror_to_errno): Likewise.

12562 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12563 (emacs_gnutls_push): Likewise.
12565 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
12567 * process.c (wait_reading_process_output): Check if GnuTLS
12568 buffered some data internally if no FDs are set for TLS
12571 * makefile.w32-in (OBJ2): Add gnutls.$(O).

12578 display_replaced_before_p argument into display_replaced_p, to
12579 make it consistent with the commentary. Fix typos in the

12612 changes in globals.h immediately force recompilation.
12613 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12614 $(CURDIR)/s/ms-w32.h.

12619 <char-direction-table>: Deleted.
12621 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12623 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12624 * doprnt.c: Include limits.h.
12625 (SIZE_MAX): New macro.
12626 (doprnt): Return a size_t value. 2nd arg is now size_t.
12627 Many local variables are now size_t instead of int or unsigned.
12628 Improve overflow protection. Support `l' modifier for integer
12629 conversions. Support %l conversion. Don't assume an EMACS_INT
12630 argument for integer conversions and for %c.
12632 * lisp.h (doprnt): Restore prototype.
12634 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12635 $(SRC)/character.h.
12637 * Makefile.in (base_obj): Add back doprnt.o.
12639 * deps.mk (doprnt.o): Add back prerequisites.
12640 (callint.o): Depend on character.h.

12880 * process.c (send_process): Adjust to the new signatures of
12881 emacs_write and emacs_gnutls_write. Do not attempt to store

13107 worth the hassle of breaking this out.
13109 * xterm.c: Make symbols static if they're not exported.
13110 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
13111 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

13210 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
13211 * lisp.h: Remove these decls.
13213 * buffer.c (buffer_count): Remove unused var.
13215 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

13217 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13218 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13219 exported only to the debugger.

13222 * atimer.h (run_all_atimers): Remove; not exported.
13224 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13225 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13226 was inaccessible from Lisp.
13227 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13228 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13230 alloc.c: Import and export fewer symbols, and remove unused items.
13231 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13233 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13234 it's not optimized away by whole-program optimization.

13236 (catchlist, handlerlist, mark_backtrace):
13237 Declare only if BYTE_MARK_STACK.

13246 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13247 (mark_backtrace): Define only if BYTE_MARK_STACK.
13248 * xdisp.c (message_enable_multibyte): Now static.
13250 Declare Lisp_Object Q* variables to be 'static' if not exported.
13251 This makes it easier for human readers (and static analyzers)
13252 to see whether these variables are used from other modules.
13253 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13254 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

13262 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
13263 Remove decls of unexported vars.
13264 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13266 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13268 Make Emacs functions such as Fatom 'static' by default.
13269 This makes it easier for human readers (and static analyzers)
13270 to see whether these functions can be called from other modules.
13271 DEFUN now defines a static function. To make the function external
13272 so that it can be used in other C modules, use the new macro DEFUE.
13273 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13274 (Finit_image_library):
13275 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13276 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13277 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13278 Remove decls, since these functions are now static.
13279 (Funintern, Fget_internal_run_time): New decls, since these functions
13280 were already external.
13282 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13283 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13289 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13290 Mark functions with DEFUE instead of DEFUN,
13291 if they are used in other modules.
13292 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13293 decls for now-static functions.
13294 * buffer.h (Fdelete_overlay): Remove decl.
13295 * callproc.c (Fgetenv_internal): Mark as internal.
13296 * composite.c (Fremove_list_of_text_properties): Remove decl.

13302 (Funintern): Remove extern decl; now in .h file where it belongs.
13303 * fileio.c (Fmake_symbolic_link): New forward static decl.
13304 * image.c (Finit_image_library): New forward static decl.
13305 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13306 * intervals.h (Fprevious_property_change):
13307 (Fremove_list_of_text_properties): Remove decls.
13308 * keyboard.c (Fthis_command_keys): Remove decl.
13309 (Fcommand_execute): New forward static decl.
13310 * keymap.c (Flookup_key): New forward static decl.
13311 (Fcopy_keymap): Now static.
13312 * keymap.h (Flookup_key): Remove decl.
13313 * process.c (Fget_process): New forward static decl.
13314 (Fprocess_datagram_address): Mark as internal.

13325 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13327 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13330 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13332 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13333 when at ZV. (Bug#8487)
13335 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13337 * charset.c (Fclear_charset_maps): Use xfree instead of free.

13341 * termcap.c (tgetent): Likewise.
13342 * xfns.c (x_default_font_parameter): Likewise.
13343 * xsettings.c (read_and_apply_settings): Likewise.
13345 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13346 (overrun_check_free): Protoize.
13348 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13350 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13351 since callers should never pass a negative size.
13352 Change the signature to match that of plain 'read' and 'write'; see
13353 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13354 * lisp.h: Update prototypes of emacs_write and emacs_read.
13356 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13358 * xdisp.c (redisplay_window): Don't try to determine the character
13359 position of the scroll margin if the window start point w->startp
13360 is outside the buffer's accessible region. (Bug#8468)
13362 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13364 Fix write-region and its subroutines for buffers > 2GB.
13365 * fileio.c (a_write, e_write): Modify declaration of arguments and
13366 local variables to support buffers larger than 2GB.
13367 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13369 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13370 argument, local variables, and return value.
13372 * lisp.h: Update prototypes of emacs_write and emacs_read.
13374 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13376 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13378 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13380 Fix more problems found by GCC 4.6.0's static checks.
13382 * xdisp.c (vmessage): Use a better test for character truncation.
13384 * charset.c (load_charset_map): <, not <=, for optimization,
13385 and to avoid potential problems with integer overflow.
13386 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13387 * casetab.c (set_identity, shuffle): Likewise.
13388 * editfns.c (Fformat): Likewise.
13389 * syntax.c (skip_chars): Likewise.
13391 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13392 This also lets GCC 4.6.0 generate slightly better loop code.
13394 * callint.c (Fcall_interactively): <, not <=, for optimization.
13395 (Fcall_interactively): Count the number of arguments produced,
13396 not the number of arguments given. This is simpler and lets GCC
13397 4.6.0 generate slightly better code.
13399 * ftfont.c: Distingish more carefully between FcChar8 and char.
13400 The previous code passed unsigned char * to a functions like
13401 strlen and xstrcasecmp that expect char *, which does not
13402 conform to the C standard.
13403 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13404 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13405 char * when the C standard requires it.
13407 * keyboard.c (read_char): Remove unused var.
13409 * eval.c: Port to Windows vsnprintf (Bug#8435).
13410 Include <limits.h>.
13411 (SIZE_MAX): Define if the headers do not.
13412 (verror): Do not give up if vsnprintf returns a negative count.
13413 Instead, grow the buffer. This ports to Windows vsnprintf, which
13414 does not conform to C99. Problem reported by Eli Zaretskii.
13415 Also, simplify the allocation scheme, by avoiding the need for
13416 calling realloc, and removing the ALLOCATED variable.
13418 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13420 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13421 But keep the doprint source code for now, as we might revamp it
13422 and use it again (Bug#8435).
13423 * lisp.h (doprnt): Remove.
13424 * Makefile.in (base_obj): Remove doprnt.o.
13425 * deps.mk (doprnt.o): Remove.
13427 error: Print 32- and 64-bit integers portably (Bug#8435).
13428 Without this change, on typical 64-bit hosts error ("...%d...", N)
13429 was used to print both 32- and 64-bit integers N, which relied on
13430 undefined behavior.
13431 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13432 * lisp.h (error, verror): Mark as printf-like functions.
13433 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13434 Report overflow in size calculations when allocating printf buffer.
13435 Do not truncate output string at its first null byte.
13436 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13437 Truncate the output at a character boundary, since vsnprintf does not
13439 * charset.c (check_iso_charset_parameter): Convert internal
13440 character to string before calling 'error', since %c now has the
13442 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13443 overflow when computing char to be passed to 'error'. Do not
13444 pass Lisp_Object to 'error'; pass the integer instead.
13445 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13446 formatted with plain %d.
13448 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13450 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13452 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13454 * xterm.c (x_catch_errors): Remove duplicate declaration.
13456 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13458 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13460 2011-04-10 Jim Meyering <meyering@redhat.com>
13462 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13463 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13464 return ssize_t not "int", and use size_t as the buffer length.
13465 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13466 * gnutls.h: Update declarations.
13467 * process.c (read_process_output): Use ssize_t, to match.
13468 (send_process): Likewise.
13470 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13472 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13474 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13476 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13477 Use unsigned char, to match FcChar8 type definition.
13479 * xterm.c (handle_one_xevent):
13480 * xmenu.c (create_and_show_popup_menu):
13481 * xselect.c (x_decline_selection_request)
13482 (x_reply_selection_request): Avoid type-punned deref of X events.
13484 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13486 Fix some uses of `int' instead of EMACS_INT.
13487 * search.c (string_match_1, fast_string_match)
13488 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13489 (scan_buffer, find_next_newline_no_quit)
13490 (find_before_next_newline, search_command, Freplace_match)
13491 (Fmatch_data): Make some `int' variables be EMACS_INT.
13493 * xdisp.c (display_count_lines): 3rd argument and return value now
13494 EMACS_INT. All callers changed.
13495 (pint2hrstr): Last argument is now EMACS_INT.
13497 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13498 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

13540 instead of using internal_with_output_to_temp_buffer.
13541 (Qhelp_form_show): New var.
13542 (syms_of_keyboard): Use DEFSYM macro.
13544 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13557 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13559 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13561 Fix more problems found by GCC 4.6.0's static checks.
13563 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

13567 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13569 * xdisp.c (vmessage): Mark as a printf-like function.
13571 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

13575 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13576 printf-like functions.
13577 (tiff_load): Add casts to remove these marks before passing them
13578 to system-supplied API.
13580 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13582 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13583 This avoids several warnings with gcc -Wstrict-overflow.
13584 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13585 directly, rather than having caller test rule sign. This avoids
13586 some unnecessary tests.
13587 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13588 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13589 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13591 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13592 (xfont_open): Avoid unnecessary tests.
13594 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13596 * composite.h, composite.c (composition_gstring_put_cache):
13597 Use EMACS_INT, not int, for length.
13599 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13600 breaking out part of COMPOSITION_DECODE_RULE.
13601 (COMPOSITION_DECODE_RULE): Use it.
13602 * composite.c (get_composition_id): Remove unused local vars,
13603 by using the new macro.
13605 * textprop.c (set_text_properties_1): Change while to do-while,
13606 since the condition is always true at first.
13608 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13609 (interval_deletion_adjustment): Return unsigned value.
13612 * process.c (list_processes_1, create_pty, read_process_output):
13613 (exec_sentinel): Remove vars that were set but not used.
13614 (create_pty): Remove unnecessary "volatile"s.
13615 (Fnetwork_interface_info): Avoid possibility of int overflow.
13616 (read_process_output): Do adaptive read buffering even if carryover.
13617 (read_process_output): Simplify nbytes computation if buffered.
13619 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
13621 * syntax.c (scan_words): Remove var that was set but not used.
13622 (update_syntax_table): Use unsigned instead of int.
13624 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

13628 * print.c (print_error_message): Avoid int overflow.
13630 * font.c (font_list_entities): Redo for clarity,
13631 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13633 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13634 (font_score): Avoid potential overflow in diff calculation.
13636 * fns.c (substring_both): Remove var that is set but not used.
13637 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13639 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13641 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13642 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13643 can always succeed if overflow has undefined behavior.
13645 * search.c (boyer_moore, wordify): Remove vars set but not used.
13646 (wordify): Omit three unnecessary tests.
13648 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13649 All callers changed. This avoids the need for an unused var.
13651 * casefiddle.c (casify_region): Remove var that is set but not used.
13653 * dired.c (file_name_completion): Remove var that is set but not used.
13655 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13657 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13658 (Finsert_file_contents): Remove unnecessary code checking fd.
13660 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13661 Check for integer overflow on size calculations.
13663 * buffer.c (Fprevious_overlay_change): Remove var that is set
13666 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13667 Remove vars that are set but not used.
13668 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13669 (timer_check_2): Mark vars as initialized.
13671 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13673 * image.c (lookup_image): Remove var that is set but not used.
13674 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13676 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13677 that are set but not used.
13679 * xfns.c (make_invisible_cursor): Don't return garbage
13680 if XCreateBitmapFromData fails (Bug#8410).
13682 * xselect.c (x_get_local_selection, x_handle_property_notify):
13683 Remove vars that are set but not used.
13685 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13686 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13688 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13689 Remove var that is set but not used.
13690 (scroll_bar_windows_size): Now size_t, not int.
13691 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13692 Check for overflow.
13694 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13695 (map_tty_color) [!defined MSDOS]: Likewise.
13697 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13699 * coding.c: Remove vars that are set but not used.
13700 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13701 All callers changed.
13702 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13703 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13704 (decode_coding_charset): Remove vars that are set but not used.
13706 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13707 that is set but not used.
13709 * print.c (print_object): Remove var that is set but not used.
13711 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13712 The gnulib version avoids calling malloc in the usual case,
13713 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13714 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13715 * filelock.c (current_lock_owner): Likewise.
13716 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13717 * sysdep.c: Include allocator.h, careadlinkat.h.
13718 (emacs_no_realloc_allocator): New static constant.
13719 (emacs_readlink): New function.
13720 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13721 ../lib/careadlinkat.h.
13723 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13725 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13726 first non-nil return value).
13728 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13730 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13731 if not defined (Bug#8403).
13733 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13735 * xdisp.c (display_count_lines): Remove parameter `start',
13736 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13737 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13738 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13740 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13741 and thereabouts. All callers changed.
13742 (get_per_char_metric): Remove parameter `f', unused since
13743 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13745 2011-04-02 Jim Meyering <meyering@redhat.com>
13747 do not dereference NULL upon failed strdup
13748 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13749 (ns_get_family): Likewise.
13751 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13753 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13755 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13757 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13760 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13762 Add lexical binding.
13764 * window.c (Ftemp_output_buffer_show): New fun.
13765 (Fsave_window_excursion):
13766 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13768 * lread.c (lisp_file_lexically_bound_p): New function.

13770 (readevalloop): Remove `evalfun' arg.
13771 Bind Qinternal_interpreter_environment.
13772 (Feval_buffer): Bind Qlexical_binding.
13773 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13775 (syms_of_lread): Declare `lexical-binding'.
13777 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13779 * keyboard.c (eval_dyn): New fun.
13780 (menu_item_eval_property): Use it.
13782 * image.c (parse_image_spec): Use Ffunctionp.
13784 * fns.c (concat, mapcar1): Accept byte-code-functions.
13786 * eval.c (Fsetq): Handle lexical vars.
13787 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13788 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13789 (FletX, Flet): Obey lexical binding.
13790 (Fcommandp): Handle closures.
13791 (Feval): New `lexical' arg.
13792 (eval_sub): New function extracted from Feval. Use it almost
13793 everywhere where Feval was used. Look up vars in lexical env.
13795 (Ffunctionp): Move from subr.el.
13796 (Ffuncall): Handle closures.
13797 (apply_lambda): Remove `eval_flags'.
13798 (funcall_lambda): Handle closures and new byte-code-functions.
13799 (Fspecial_variable_p): New function.
13800 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13801 but without exporting it to Lisp.
13803 * doc.c (Fdocumentation, store_function_docstring):
13804 * data.c (Finteractive_form): Handle closures.
13806 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13809 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13811 (exec_byte_code): New function extracted from Fbyte_code to handle new
13812 calling convention for byte-code-functions. Add new byte-codes.
13814 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13816 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13818 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13820 * xdisp.c (redisplay_internal): Fix prototype.
13822 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13824 * xdisp.c (SCROLL_LIMIT): New macro.
13825 (try_scrolling): Use it when setting scroll_limit.
13826 Limit scrolling to 100 screen lines.
13827 (redisplay_window): Even when falling back on "recentering",
13828 position point in the window according to scroll-conservatively,
13829 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13831 (try_scrolling): When point is above the window, allow searching
13832 as far as scroll_max, or one screenful, to compute vertical
13833 distance from PT to the scroll margin position. This prevents
13834 try_scrolling from unnecessarily failing when
13835 scroll-conservatively is set to a value slightly larger than the
13836 window height. Clean up the case of PT below the margin at bottom
13837 of window: scroll_max can no longer be INT_MAX. When aggressive
13838 scrolling is in use, don't let point enter the opposite scroll
13839 margin as result of the scroll.
13840 (syms_of_xdisp) <scroll-conservatively>: Document the
13841 threshold of 100 lines for never-recentering scrolling.
13843 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13845 * dispextern.h (move_it_by_lines):
13846 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13847 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13848 (message_log_check_duplicate): Remove parameters `prev_bol' and
13849 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13850 (redisplay_internal): Remove parameter `preserve_echo_area',
13851 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13853 * indent.c (Fvertical_motion):
13854 * window.c (window_scroll_pixel_based, Frecenter):
13855 Don't pass `need_y_p' to `move_it_by_lines'.
13857 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13859 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13860 steal a few bits to be more compact.
13861 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13862 Remove unneeded casts.
13864 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13866 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13868 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13869 binding" message (bug#7967).
13871 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13873 Fix more problems found by GCC 4.6.0's static checks.
13875 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13876 Remove unused local var.
13878 * editfns.c (Fmessage_box): Remove unused local var.
13880 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13881 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13882 Omit unused local vars.
13883 * window.c (shrink_windows): Omit unused local var.
13884 * menu.c (digest_single_submenu): Omit unused local var.
13885 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13886 Omit unused local var.
13888 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13889 Don't assume string length fits in int.
13890 (keyremap_step, read_key_sequence): Use size_t for sizes.
13891 (read_key_sequence): Don't check last_real_key_start redundantly.
13893 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13894 instead of alloca (Bug#8344).
13896 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13897 (Fbacktrace_frame): Don't assume nframes fits in int.
13899 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13901 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13904 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13906 * cm.c (calccost): Turn while-do into do-while, for clarity.
13908 * keyboard.c (syms_of_keyboard): Use the same style as later
13909 in this function when indexing through an array. This also
13910 works around GCC bug 48267.
13912 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13914 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13916 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13917 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13919 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13920 This avoids undefined behavior on integer overflow, and is a bit
13921 more convenient anyway since it is compared to a size_t variable.
13923 Variadic C functions now count arguments with size_t, not int.
13924 This avoids an unnecessary limitation on 64-bit machines, which
13925 caused (substring ...) to crash on large vectors (Bug#8344).
13926 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13927 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13928 All variadic functions and their callers changed accordingly.

13935 * fns.c (concat): Likewise.
13936 * frame.c (x_set_frame_parameters): Likewise.
13937 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13938 0 if not found, not -1. All callers changed.
13940 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13941 (stack_copy_size): Now size_t, not int.
13942 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13944 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13946 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13947 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13948 All callers changed.
13950 * lisp.h (multibyte_char_to_unibyte):
13951 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13952 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13953 * character.h (CHAR_TO_BYTE8):
13954 * cmds.c (internal_self_insert):
13955 * editfns.c (general_insert_function):
13956 * keymap.c (push_key_description):
13957 * search.c (Freplace_match):
13958 * xdisp.c (message_dolog, set_message_1): All callers changed.
13960 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13962 * keyboard.c (safe_run_hook_funcall): New function.
13963 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13964 don't set the hook to nil, but remove the offending function instead.
13965 (Qcommand_hook_internal): Remove, unused.
13966 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13967 Vcommand_hook_internal.
13969 * eval.c (enum run_hooks_condition): Remove.

14148 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14150 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14151 unconditionally since it does the check itself.
14153 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14155 Fix more problems found by GCC 4.5.2's static checks.
14157 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14158 the first time through the loop, since we know p0 < p1 then.
14159 This also avoids a gcc -Wstrict-overflow warning.
14161 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14162 leading to a memory leak, possible in functions like
14163 load_charset_map_from_file that can allocate an unbounded number
14164 of objects (Bug#8318).
14166 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14167 that could (at least in theory) be that large.
14169 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14170 This is less likely to overflow, and avoids undefined behavior if
14171 overflow does occur. All callers changed. Use strtoul to scan
14172 for the unsigned long integer.

14189 * process.c (Fmake_network_process): Use socklen_t, not int,
14190 where POSIX says socklen_t is required in portable programs.
14191 This fixes a porting bug on hosts like 64-bit HP-UX, where
14192 socklen_t is wider than int (Bug#8277).
14193 (Fmake_network_process, server_accept_connection):
14194 (wait_reading_process_output, read_process_output):

14209 Include tparam.h instead, since it declares them.
14210 * cm.h (PC): Remove extern decl; tparam.h now does this.
14211 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14212 * terminfo.c: Include tparam.h, to check interfaces.
14213 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14214 (tparam): Adjust signature to match interface in tparam.h;
14215 this removes some undefined behavior. Check that outstring and len
14216 are zero, which they always are with Emacs.
14217 * tparam.h (PC, BC, UP): New extern decls.
14219 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14220 (xftfont_open): Rename locals to avoid shadowing.

14259 Fix pointer signedness.
14260 (alsa_choose_format): Remove unused local var.
14261 (wav_play): Initialize a variable to 0, to prevent undefined
14262 behavior (Bug#8278).
14264 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14266 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14268 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14269 clobbering (Bug#8298).
14270 * sysdep.c (sys_subshell): Likewise.
14271 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14273 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14274 This should get cleaned up, so that child_setup has the
14275 same signature on all platforms.
14277 * callproc.c (call_process_cleanup): Now static.
14278 (relocate_fd): Rename locals to avoid shadowing.
14280 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14282 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14283 not to be necessary, and produces flickering.
14285 2011-03-20 Glenn Morris <rgm@gnu.org>
14287 * config.in: Remove file.
14289 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

14422 gcc -Wbad-function-cast warning.
14423 (default_value, arithcompare, arith_driver, arith_error): Now static.
14424 (store_symval_forwarding): Rename local to avoid shadowing.
14425 (Fmake_variable_buffer_local, Fmake_local_variable):
14426 Mark variables as initialized.

14431 Rename locals to avoid shadowing.
14432 (mark_stack): Move local variables into the #ifdef region where
14434 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
14435 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
14437 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
14438 (GC_STRING_CHARS): Remove; not used.
14439 (Fmemory_limit): Cast sbrk's returned value to char *.
14441 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14442 avoids undefined behavior in theory.
14444 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14446 Use functions, not macros, for up- and down-casing (Bug#8254).
14447 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14448 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14449 to use the following functions instead of these macros.
14450 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14451 EMACS_INT, since callers assume the returned value fits in int.
14452 (upcase1): Likewise, for UPCASE_TABLE.
14453 (uppercasep, lowercasep, upcase): New static inline functions.
14454 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14455 the race-condition problem in the old DOWNCASE.
14457 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
14458 Rename locals to avoid shadowing.
14459 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14460 (regex_compile, re_search_2, re_match_2_internal):
14461 Remove unused local vars.

14463 which gcc can warn about.
14464 (regex_compile, re_match_2_internal): Mark locals as initialized.
14465 (RETALLOC_IF): Define only if needed.
14466 (WORDCHAR_P): Likewise. This one is never needed, but is used
14467 only in a comment talking about a compiler bug, so put inside
14468 the #if 0 of that comment.
14469 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14470 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14473 * search.c (boyer_moore): Rename locals to avoid shadowing.
14474 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

14485 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.

14496 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14497 New macros, so that the caller can use some names other than
14498 gcpro1, gcpro2, etc.
14499 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14501 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14502 argument, for consistency with GCPRO2_VAR, etc: it is now the
14503 prefix of the variable, not the variable itself. All uses
14505 * dired.c (directory_files_internal, file_name_completion):
14506 Rename locals to avoid shadowing.
14508 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14509 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14510 dired.c's scmp function, had undefined behavior.
14511 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14512 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14513 * buffer.h: ... to here, because these macros use current_buffer,
14514 and the new implementation with inline functions needs to have
14515 current_buffer in scope now, rather than later when the macros
14517 (downcase, upcase1): New static inline functions.
14518 (DOWNCASE, UPCASE1): Reimplement using these functions.
14519 This avoids undefined behavior in expressions like
14520 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14521 from race conditions in accessing the global variables
14522 case_temp1 and case_temp2.
14523 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14524 * lisp.h (case_temp1, case_temp2): Remove their decls.
14525 * character.h (ASCII_CHAR_P): Move from here ...
14526 * lisp.h: ... to here, so that the inline functions mentioned
14527 above can use them.
14529 * dired.c (directory_files_internal_unwind): Now static.
14531 * fileio.c (file_name_as_directory, directory_file_name):
14532 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14534 (file_name_as_directory): Use const pointers when appropriate.
14535 (Fexpand_file_name): Likewise. In particular, newdir might
14536 point at constant storage, so make it a const pointer.
14537 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14538 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14540 (Fset_file_times, Finsert_file_contents, auto_save_error):

14545 to avoid shadowing.
14547 * marker.c (bytepos_to_charpos): Remove; unused.
14549 * lisp.h (verify_bytepos, count_markers): New decls,
14550 so that gcc does not warn that these functions aren't declared.
14552 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14553 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14554 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14555 (copy_text): Remove unused local var.
14557 * filelock.c (within_one_second): Now static.
14558 (lock_file_1): Rename local to avoid shadowing.
14560 * buffer.c (fix_overlays_before): Mark locals as initialized.
14561 (fix_start_end_in_overlays): Likewise. This function should be
14562 simplified by using pointers-to-pointers, but that's a different
14564 (switch_to_buffer_1): Now static.
14565 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14566 (report_overlay_modification): Rename locals to avoid shadowing.
14568 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14569 Fix pointer signedness issue.
14570 (sys_subshell): Mark local as volatile if checking for lint,
14571 to suppress a gcc -Wclobbered warning that does not seem to be right.
14572 (MAXPATHLEN): Define only if needed.
14574 * process.c (serial_open, serial_configure): Move decls from here ...
14575 * systty.h: ... to here, so that they can be checked.
14577 * fns.c (get_random, seed_random): Move extern decls from here ...
14578 * lisp.h: ... to here, so that they can be checked.
14580 * sysdep.c (reset_io): Now static.
14581 (wait_for_termination_signal): Remove; unused.
14583 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

14588 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14589 (describe_map_tree):
14590 Rename locals to avoid shadowing.
14592 * keyboard.c: Declare functions static if they are not used elsewhere.

14741 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14742 reports time overflow. See
