62 * w32.c (init_environment): Change the default values of many
63 environment variables in dflt_envvars[] to NULL, to avoid pushing
64 them into environment when they were not already defined. Remove
65 the code that deletes site-lisp subdirectories from the default
66 value of EMACSLOADPATH, as it is no longer needed.
67 (check_windows_init_file): Now external, not static. Use
68 Vload_path as is, without adding anything, as this function is now
69 called when Vload_path is already set up.
71 * w32.h (check_windows_init_file): Add prototype.
73 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

78 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
79 any, in the DEFALT argument into the root of the Emacs build or
80 installation tree, as appropriate.
82 * callproc.c (init_callproc_1): Call decode_env_path instead of
83 doing its equivalent by hand.
84 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
85 the code that sets Vexec_path run on MS-Windows.
87 * lread.c (init_lread): Add comments to #ifdef's.
89 * msdos.c (dos_set_window_size, IT_update_begin)
90 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

97 Now constants, not macros.
99 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>

102 These casts are no longer needed now that we assume C89 or later,
103 since they involve casting to or from void *.
104 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
105 (make_pure_float, make_pure_vector):
106 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

116 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
117 Remove unnecessary pointer casts.
118 * alloc.c (record_xmalloc): New function.
119 * lisp.h (record_xmalloc): New decl.
120 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
121 more like a function. This is because the pointer cast is not
122 needed. All uses changed.
123 * print.c (print_string, print_error_message): Avoid length recalc.
125 Improve fix for macroexp crash with debugging (Bug#12118).
126 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
127 ARRAY_MARK_FLAG when checking subscripts, because ASET is
128 not supposed to be invoked from the garbage collector.
129 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
130 (gc_aset): New function, which is like ASET but can be
131 used in the garbage collector.
132 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

144 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
145 (map_w32_filename): Improve commentary. Simplify switch.
146 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
147 headers (most versions of MinGW w32api don't).
148 (get_security_info, create_symbolic_link)
149 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
151 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
152 in the argument file name.
153 (sys_access): Call unc_volume_file_attributes only if
154 GetFileAttributes fails with network-related error codes.
155 (sys_rename): Diagnose renaming of a symlink when the user doesn't
156 have the required privileges.
157 (get_file_security_desc_by_name): Renamed from
158 get_file_security_desc.
159 (stat_worker): New function, with most of the guts of 'stat', and
160 with addition of handling of symlinks and support for 'lstat'. If
161 possible, get file's attributes and security information by
162 handle, not by name. Produce S_IFLNK bit for symlinks, when
164 (stat, lstat): New functions, call 'stat_worker'.
165 (symlink, readlink, careadlinkat): Rewritten to create and resolve
166 symlinks when the underlying filesystem supports them.
168 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
170 Fix macroexp crash on Windows with debugging (Bug#12118).
171 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
172 checking subscripts; problem introduced with the recent
173 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
174 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
175 since it's used in non-static inline functions now.
177 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
178 Don't assume buffer size fits in 'int'. Remove unused local.
180 Use C99-style 'extern inline' if available.
181 * buffer.h (BUFFER_INLINE):
182 * category.h (CATEGORY_INLINE):

198 * composite.c (COMPOSITE_INLINE):
199 * dispnew.c (DISPEXTERN_INLINE):
200 * sysdep.c (SYSTIME_INLINE):
201 Define to EXTERN_INLINE, so that the corresponding functions
202 are compiled into code.
203 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
204 (INLINE_HEADER_END): New macros.
205 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

227 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
229 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
230 This how ASET and AREF are supposed to work, and makes
231 it easier to think about future improvements. See
232 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
233 * charset.h (set_charset_attr): New function.

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

643 2012-07-27 Eli Zaretskii <eliz@gnu.org>
645 * alloc.c (listn): Fix the order the arguments are consed onto the
648 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
649 enumeration constants, as PURE and HEAP are too general, and clash
650 with other headers and sources, such as gmalloc.c and the
651 MS-Windows system headers. All users changed.
653 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
655 Revert last save_excursion_save and save_excursion_restore changes.
656 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

668 Improve GDB symbol export (Bug#12036).
669 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
670 arms of an 'if', not using conditional expressions; otherwise GDB
671 complains about the types in the unevaluated arm when the argument
672 is an integer literal.
673 (xgetint): Simplify expression.
674 * alloc.c (gdb_make_enums_visible): New constant. This ports to
675 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
676 Zaretskii in <http://bugs.gnu.org/12036#13>.
677 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
678 needed now that we have gdb_make_enums_visible.

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

737 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
738 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
739 not be usable in #if. This simplifies things.
741 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
743 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
745 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

748 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
749 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
750 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
751 Adjust to changes in lisp.h and emacs.c, by using
752 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
753 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
754 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
755 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
756 instead of gdb_valbits.
757 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
758 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
759 instead of gdb_array_mark_flag.
760 (xboolvector): Get size from $->size, not $->header.size.
761 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
762 (xreload, hook-run, hookpost-run): Remove.
763 * emacs.c: Include <verify.h>.
764 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
765 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
767 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
768 (gdb_USE_LSB_TAG): New enum constants.
769 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
770 Also define these as enum constants, so they're visible to GDB.

772 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
773 as constants, so they're visible to GDB.
774 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

776 Now enum constants, not macros, so they're visible to GDB.
777 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
778 more convenient now. All uses changed.
779 (VALMASK) [USE_LSB_TAG]: Also define in this case.

790 add argument, tune behavior, and adjust all callers.
792 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
794 Use typedef for EMACS_INT, EMACS_UINT.
795 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
796 than macros. This simplifies debugging in the usual case, since
797 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
798 and it allows expressions involving EMACS_INT casts.
799 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
801 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

814 * buffer.c (Fkill_buffer): Adjust indirection counters when the
815 buffer is definitely dead. This should really fix an issue reported
816 by Christoph Scholtes again. (Bug#12007).
817 (init_buffer_once): Initialize indirection counters of
818 buffer_defaults and buffer_local_symbols (for sanity and safety).
820 2012-07-24 Eli Zaretskii <eliz@gnu.org>
822 * xdisp.c (init_iterator): Don't compute dimensions of truncation
823 and continuation glyphs on tooltip frames, leave them at zero.
824 Avoids continued lines in tooltips. (Bug#11832)
826 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
828 Simplify copy_overlay.
829 * buffer.c (copy_overlay): Simplify. Use build_marker.

835 or invalid. (Bug#12025)
837 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as

853 Swap buffer text indirection counters in Fbuffer_swap_text.
854 * buffer.c (Fbuffer_swap_text): Swap indirections too.
855 This avoids crash reported by Christoph Scholtes at
856 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
858 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
860 * nsmenu.m (Popdown_data): New struct.
861 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
863 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
864 (initWithContentRect): Make imgView and contentView non-static
865 and autorelease them. Also autorelease img and matrix (Bug#12005).

883 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
885 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
886 as it's limited by the amount of memory, not by INT_MAX.
888 2012-07-21 Eli Zaretskii <eliz@gnu.org>
890 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
891 in special-event-map. See the discussion at

1614 * s/aix4-2.h (unix): Remove; no longer needed.
1616 EMACS_TIME simplification (Bug#11875).
1617 This replaces macros (which typically do not work in GDB)

1619 The functional style also makes code easier to read and maintain.
1620 * systime.h: Include <sys/time.h> on all hosts, not just if
1621 WINDOWSNT, since 'struct timeval' is needed in general.

1637 (add_emacs_time, sub_emacs_time): New functions.
1638 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1661 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1662 Prefer snprintf to strncpy.
1663 * nsterm.m (ns_term_init):
1664 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1665 * nsterm.m (ns_term_init):
1666 Avoid the need for strncpy, by using build_string or
1667 make_unibyte_string directly. Use dtoastr, not snprintf.
1668 * process.c (Fmake_network_process): Diagnose service names that
1669 are too long, rather than silently truncating them or creating
1670 non-null-terminated names.
1671 (Fnetwork_interface_info): Likewise, for interface names.
1672 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1673 Prefer sprintf to strncat.

1687 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1688 where argument type is known to be a Lisp_Cons.

1743 O_RDONLY already includes it).
1745 Stop ns builds setting the EMACSLOADPATH environment variable.
1746 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1747 Now it does not set EMACSLOADPATH, just returns the load-path string.

1749 * lread.c [HAVE_NS]: Include nsterm.h.
1750 (init_lread) [HAVE_NS]: Use ns_load_path.

1760 (ns_init_paths): Do not set EMACSPATH.

1820 Move marker debugging code under MARKER_DEBUG.
1821 * marker.c (MARKER_DEBUG): Move marker debugging code under
1822 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1823 for bootstrap with --enable-checking (~3x slowdown reported
1824 by Juanma Barranquero <lekktu@gmail.com>).

1834 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1835 has no font, use the frame's font. (Bug#11813)
1836 (display_line): Add commentary about displaying truncation glyphs
1838 (produce_special_glyphs): Move here from term.c.
1840 * term.c (produce_special_glyphs): Move to xdisp.c.
1842 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1845 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1847 * xdisp.c (display_line): Avoid warning about implicit declaration
1850 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1852 * lisp.h: Remove empty conditional.
1854 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1856 * lread.c (load_path_check): Now static.
1858 Fix some minor --with-ns problems found by static checking.
1859 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1860 (x_set_font) [!HAVE_X_WINDOWS]:
1861 * image.c (xpm_load_image) [HAVE_NS]:
1862 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1863 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1864 Remove unused local.
1865 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1866 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1867 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1868 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1869 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1870 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1871 Fix pointer signedness problem.
1872 * xfaces.c (FRAME_X_FONT_TABLE):
1873 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1875 2012-07-07 Glenn Morris <rgm@gnu.org>
1877 * lread.c (load_path_check): New function, split from init_lread.
1878 (init_lread): Reorganize. Motivation:
1879 If EMACSLOADPATH is set, check/warn about that rather than the
1880 defaults, which we are not going to use. Hence we can remove
1881 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1882 Don't warn if site-lisp directories are missing.
1883 If not installed, start from a blank load-path, since
1884 PATH_LOADSEARCH refers to the eventual installation directories.
1886 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1888 Support truncation and continuation glyphs on GUI frames, when
1889 fringes are disabled. (Bug#11832)
1890 * xdisp.c (init_iterator): Get dimensions of truncation and
1891 continuation glyphs even if on GUI frames. Adjust
1892 it->last_visible_x on GUI frames when the left or right fringes,
1893 or both, are absent.
1894 (start_display, move_it_in_display_line_to): Handle the case of a
1895 GUI frame without a fringe to display continuation or truncation
1897 (insert_left_trunc_glyphs): Support GUI frames: make sure
1898 truncation glyphs overwrite enough glyphs from the current line to
1899 have sufficient space in pixels.
1900 (display_line): Support truncation and continuation glyphs on GUI
1901 frames. If some spare pixels are left on the line after inserting
1902 the truncation glyphs, fill that space with a stretch glyph of a
1903 suitably computed width.
1905 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1906 produce_glyphs, to support GUI sessions.
1908 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1910 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1912 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1914 Do not require float-time's arg to fit in time_t (Bug#11825).
1915 This works better on hosts where time_t is unsigned, and where
1916 float-time is applied to the (negative) difference between two times.
1917 * editfns.c (decode_time_components): Last arg is now double *,
1918 not int *, and means to store all the result as a double, without
1919 worrying about whether the seconds part fits in time_t.
1920 All callers changed.
1921 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1922 All callers changed.
1923 (Ffloat_time): Do not fail merely because the specified time falls
1924 outside of time_t range.
1926 2012-07-07 Glenn Morris <rgm@gnu.org>
1928 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1929 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1930 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1932 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1934 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1935 Update dependencies.
1937 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1939 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1941 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1942 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1943 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1944 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1945 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1946 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1948 * xfont.c (compare_font_names): Redo to omit the need for casts.
1950 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1952 * xfns.c (Fx_change_window_property): Doc fix.
1953 * w32fns.c (Fx_change_window_property): Doc fix.
1955 * w32fns.c (Fx_window_property): Accept the same arguments as the
1956 X Windows version. Doc fix.
1957 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1959 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1960 Eli Zaretskii <eliz@gnu.org>
1962 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1963 Windows-specific code from nt/config.nt moved here.
1964 Obsolete settings removed.
1966 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1968 * process.c: Avoid unnecessary calls to gettime.
1969 (wait_reading_process_output): Don't get the time of day
1970 when gobbling data immediately and not waiting, as there's no need
1971 for it in that case. This removes a FIXME.
1973 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1975 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1976 is defined (Bug#11768).
1978 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1980 Fix marker debugging code.
1981 * marker.c (byte_char_debug_check): Do not perform the check
1982 if buffer is not multibyte.
1983 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1984 Call byte_char_debug_check with correct arguments.
1986 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1988 Compile marker debugging code only if ENABLE_CHECKING is defined.
1989 * marker.c (byte_char_debug_check, count_markers):
1990 Use only if ENABLE_CHECKING is defined.
1991 (byte_debug_flag): Remove.
1992 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1993 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1995 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1997 Avoid code repetition in marker-related functions.
1998 * marker.c (attach_marker): New function.
1999 (Fset_marker, set_marker_restricted, set_marker_both)
2000 (set_marker_restricted_both): Use it.
2001 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2002 Consistently rename charno to charpos.
2003 (marker_position): Add eassert.
2004 (marker_byte_position): Convert to eassert.
2006 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2008 Simplify list operations in unchain_overlay and unchain_marker.
2009 * buffer.c (unchain_overlay): Simplify. Add comment.
2010 * marker.c (unchain_marker): Simplify. Fix comments.

2014 Introduce fast path for the widely used marker operation.
2015 * alloc.c (build_marker): New function.
2016 * lisp.h (build_marker): New prototype.
2017 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
2018 * composite.c (autocmp_chars): Likewise.
2019 * editfns.c (buildmark): Remove.
2020 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2021 (save_restriction_save): Use build_marker.
2022 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2023 * window.c (save_window_save): Likewise.
2025 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2027 Do not use Fdelete_overlay in delete_all_overlays
2028 to avoid redundant calls to unchain_overlay.
2029 * buffer.c (drop_overlay): New function.
2030 (delete_all_overlays, Fdelete_overlay): Use it.
2031 * minibuf.c (get_minibuffer): Fix comment.
2033 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2035 Port to OpenBSD 5.1 amd64.
2036 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2037 This is needed for OpenBSD, and should be harmless on all BSD systems.
2038 Also, include <sys/sysctl.h>, as it should be available on all
2039 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2040 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2041 use p_pid member, not kp_proc.pid.
2043 2012-07-06 Glenn Morris <rgm@gnu.org>
2045 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2047 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2049 More xmalloc and related cleanup.
2050 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2051 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
2052 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
2053 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
2054 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2055 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2056 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2057 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2058 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2060 Omit needless casts involving void * pointers and allocation.
2061 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2062 as the former is more robust if P's type is changed.
2063 Prefer xzalloc to xmalloc + memset 0.
2064 Simplify malloc-or-realloc to realloc.
2065 Don't worry about xmalloc returning a null pointer.
2066 Prefer xstrdup to xmalloc + strcpy.
2067 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2069 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2070 alloca of a constant.
2072 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2074 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2075 hscroll is larger than the line width. Fixes long and futile
2076 looping inside extend_face_to_end_of_line (on a TTY) producing
2077 glyphs that are not needed and thrown away.
2079 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2081 * marker.c (set_marker_restricted_both): Simplify by using
2084 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2086 * editfns.c (region_limit): Simplify by using clip_to_bounds.
2088 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
2090 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
2091 not defined (Bug#11768).
2092 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2093 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2094 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2095 followed by gtk_box_set_homogeneous (Bug#11768).
2096 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2097 (update_theme_scrollbar_width, xg_create_scroll_bar):
2098 Use gtk_scrollbar_new (Bug#11768).
2099 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2100 (is_box_type): New function (Bug#11768).
2101 (xg_tool_item_stale_p): Call is_box_type.
2102 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2103 with default display (Bug#11768).
2105 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2107 * xdisp.c (window_hscroll_limited): New function.
2108 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2109 coordinates when window's hscroll is set to insanely large
2112 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2114 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2115 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2117 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2120 * lisp.h (xzalloc): New prototype. Omit needless casts.
2121 * alloc.c (xzalloc): New function. Omit needless casts.
2122 * charset.c: Omit needless casts. Convert all calls to
2123 xmalloc with following memset to xzalloc.
2124 * dispnew.c: Likewise.
2125 * fringe.c: Likewise.
2126 * image.c: Likewise.

2173 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2175 * fileio.c (time_error_value): Check the right error number.
2176 Problem reported by Troels Nielsen in
2177 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2179 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2181 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2182 This should be fixed in a better way; see Eli Zaretskii in
2183 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2184 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2186 * fileio.c (time_error_value): Rename from special_mtime.
2187 The old name's problems were noted by Eli Zaretskii in
2188 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2190 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2191 This variable's comment says Emacs needs at least one GDB-visible
2192 symbol of type enum pvec_type, to work around GDB problems.
2193 The symbol's value doesn't matter.
2195 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2196 that causes compilation to fail on pre-C99 compilers.
2198 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2200 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2201 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2203 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2205 * buffer.c (init_buffer_once): Fix initialization of
2206 headers for buffer_defaults and buffer_local_symbols.
2207 Reported by Juanma Barranquero <lekktu@gmail.com>.
2209 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2211 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2212 * lisp.h (enum pvec_type): Use fewer bits.
2213 (PSEUDOVECTOR_SIZE_BITS): New constant.
2214 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2215 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2216 change in pvec_type.
2217 (PSEUDOVECTOR_TYPEP): New macro.
2218 (TYPED_PSEUDOVECTORP): Use it.
2219 * fns.c (internal_equal): Adapt code to extract pvectype.
2220 * emacs.c (gdb_pvec_type): Update type.
2221 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2222 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2223 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2224 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2225 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2226 abusing vector->header.next.nbytes.
2227 (live_vector_p): Use PVEC_TYPE.
2228 (mark_object): Adapt code to extract pvectype. Use switch.
2230 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2232 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2233 Tighten new eassert a bit.
2235 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2237 Fix compilation with --enable-gcc-warnings and -O1
2239 * doprnt.c (doprnt): Change type of tem to int, initialize
2240 to avoid compiler warning. Add eassert.
2241 * search.c (simple_search): Initialize match_byte to avoid
2242 compiler warning. Add eassert.
2244 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2246 Avoid weird behavior with large horizontal scrolls.
2247 Without this change, for example, large hscroll values would
2248 mess up Emacs's display on Fedora 15 x86, presumably due to
2249 overflows in int calculations in the display code.
2250 Also, if buffers had long lines, Emacs would freeze.
2251 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2252 (set_window_hscroll): New function, containing the old guts of
2253 Fset_window_hscroll. Return the clipped value.
2254 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2255 This avoids the need to check against PTRDIFF_MAX.
2257 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2259 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2261 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2263 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2265 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2266 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2267 since GCC 4.4.6 issues a bogus warning for them.
2269 Fix bugs in file timestamp newness comparisons.
2270 * fileio.c (Ffile_newer_than_file_p):
2271 * lread.c (Fload): Use full timestamp resolution of files,
2272 not just the 1-second resolution, so that files that are only
2273 slightly newer still count as newer.
2274 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2275 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2277 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2279 * fileio.c: Improve handling of file time marker. (Bug#11852)
2280 (special_mtime): New function.
2281 (Finsert_file_contents, Fverify_visited_file_modtime):
2282 Use it to set special mtime values consistently.
2284 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2286 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2287 marker for non-existing file. (Bug#11852)
2289 2012-07-03 Glenn Morris <rgm@gnu.org>
2291 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN

2341 values which aren't power of 2.
2342 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2343 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users

2348 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

2354 * alloc.c (allocate_vector_block): Remove redundant
2355 calls to mallopt if DOUG_LEA_MALLOC is defined.
2356 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2357 avoid calls to mallopt if zero_vector is returned.
2359 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2361 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2362 is enabled, avoid dereferencing NULL current_sblock if
2365 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2367 Cleanup basic buffer management.
2368 * buffer.h (struct buffer): Change layout to use generic vector
2369 marking code. Fix some comments. Change type of 'clip_changed'
2370 to bitfield. Remove unused #ifndef old.

2377 * alloc.c (allocate_buffer): Adjust to match new layout of
2378 struct buffer. Fix comment.

2381 Lisp area of struct buffer.
2382 (mark_object): Use it. Adjust marking of misc objects
2383 and related comments.
2385 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2387 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2388 wrapper that is not needed because the wrapped code is a no-op (zero
2389 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2390 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2392 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2394 * alloc.c (mark_buffer): Simplify. Remove prototype.
2395 (mark_object): Add comment. Reorganize marking of vector-like
2396 objects. Use CHECK_LIVE for all vector-like objects except buffers
2397 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2398 redundant calls to mark_vectorlike for bool vectors.
2400 2012-06-30 Glenn Morris <rgm@gnu.org>
2402 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2404 * epaths.in (PATH_SITELOADSEARCH): New.
2405 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2406 This is rather than relying on --enable-locallisppath elements
2407 having "site-lisp" in their names. (Bug#10208#25, 11658)
2409 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2411 * w32proc.c (sys_select): Accept and ignore one more argument.
2413 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2415 * sysselect.h [DOS_NT]: Don't include sys/select.h.

2420 * process.c (sys_select):
2421 * msdos.c (sys_select): Accept one more argument and ignore it.
2423 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2424 adapt data types and code to that.
2427 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2428 which clashes with the gnulib function of the same name.
2430 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2432 * font.c (font_style_to_value, font_style_symbolic)

2443 * xdisp.c (try_window_id): Undo last change.
2445 * w32.c (getwd): Adjust commentary about startup_dir.
2446 (init_environment): Always call sys_access, even in non-MSVC
2447 builds. Don't chdir to the directory of the Emacs executable.
2448 This undoes code from 1997 which was justified by the need to
2449 "avoid conflicts when removing and renaming directories". But its
2450 downside was that every relative file name was being interpreted
2451 relative to the directory of the Emacs executable, which can never
2452 be TRT. In particular, it broke sys_access when called with
2453 relative file names.
2454 (sys_access): Map GetLastError to errno.
2456 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

2502 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2503 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2504 from EMACS_INT to ptrdiff_t.

2646 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2648 Use sprintf return value instead of invoking strlen on result.
2649 In the old days this wasn't portable, since some sprintf
2650 implementations returned char *. But they died out years ago and
2651 Emacs already assumes sprintf returns int.
2652 Similarly for float_to_string.
2653 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2661 Use sprintf or float_to_string result to avoid need to call strlen.
2662 * data.c (Fnumber_to_string):
2663 Use make_unibyte_string, since the string must be ASCII.
2664 * lisp.h, print.c (float_to_string): Now returns int length.
2665 * term.c (produce_glyphless_glyph):
2666 Use sprintf result rather than recomputing it.

2701 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2706 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2707 instead of truncating it to 63 (admittedly a generous limit).

2790 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2791 Privately reported by Herbert J. Skuhra.
2792 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

2803 language ID in the event parameters.
2805 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2829 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2830 Privately reported by Herbert J. Skuhra.

2833 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2834 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2835 Don't assume EMACS_TIME and struct timeval are the same type.
2837 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2839 Support higher-resolution time stamps (Bug#9000).
2840 The time stamps are only nanosecond-resolution at the C level,
2841 since that's the best that any real-world system supports now.
2842 But they are picosecond-resolution at the Lisp level, as that's
2843 easy, and leaves room for future OS improvements.
2845 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2848 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2849 Don't get current time unless it's needed.
2851 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2852 now provides it if it's absent.
2853 (start_atimer): Port to higher-res time stamps.
2854 Check for time stamp overflow. Don't get current time more
2855 often than is needed.
2857 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2858 Include systime.h, not time.h.

2865 (struct image): Timestamp now has higher resolution.
2867 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2868 has at least microseconds now. All uses removed.
2869 (update_frame, update_single_window, update_window, update_frame_1)
2870 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2872 * editfns.c (time_overflow): Now extern.
2873 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2880 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2881 Report an error if the time is invalid, rather than having the caller
2884 * fileio.c: Include <stat-time.h>
2885 (Fcopy_file): Copy higher-resolution time stamps.
2886 Prefer to set the time stamp via a file descriptor if that works.

2888 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2889 (Fvisited_file_modtime, Fset_visited_file_modtime):
2890 Support higher-resolution time stamps.
2892 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2894 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2896 * image.c (prepare_image_for_display, clear_image_cache)
2897 (lookup_image): Port to higer-resolution time stamps.
2899 * keyboard.c (start_polling, bind_polling_period):
2900 Check for time stamp overflow.
2901 (read_char, kbd_buffer_get_event, timer_start_idle)
2902 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2903 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2904 Port to higher-resolution time stamps. Do not assume time_t is signed.
2905 (decode_timer): New function. Timers are now vectors of length 9,
2906 not 8, to accommodate the picosecond component.
2907 (timer_check_2): Use it.
2909 * nsterm.m (select_timeout, timeval_subtract): Remove.
2910 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2911 as they're a bit more accurate and handle overflow better.
2912 (ns_select): Change prototype to be compatible with pselect.
2913 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2914 * nsterm.h (ns_select): Adjust prototype.
2916 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2917 us-resolution time stamps.
2918 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2920 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2922 * lisp.h (time_overflow): New decl.
2923 (wait_reading_process_output): First arg is now intmax_t, not int,
2924 to accommodate larger waits.
2926 * process.h (struct Lisp_Process.read_output_delay):
2927 Now counts nanoseconds, not microseconds.
2928 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2930 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2931 (wait_reading_process_output):
2932 Port to ns-resolution time stamps.
2933 (Faccept_process_output, wait_reading_process_output):
2934 Check for time stamp overflow. Do not assume time_t is signed.
2935 (select_wrapper): Remove; we now use pselect.
2936 (Fprocess_attributes): Now generates ns-resolution time stamps.
2938 * sysdep.c: Include utimens.h. Don't include utime.h
2939 or worry about struct utimbuf; gnulib does that for us now.
2940 (gettimeofday): Remove; gnulib provides a substitute.
2941 (make_timeval): New function.
2942 (set_file_times): Now sets ns-resolution time stamps.
2943 New arg FD; all uses changed.
2944 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2945 (system_process_attributes):
2946 Now returns ns-resolution time stamp. All uses changed.
2947 Check for time stamp overflow.
2949 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2950 provides a substitute now.
2952 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2953 since it guarantees struct timespec.
2954 (EMACS_TIME): Now struct timespec, so that we can support
2955 ns-resolution time stamps.
2956 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2957 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2958 (EMACS_USECS): Remove.
2959 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2960 so multiply the arg by 1000 before storing it.
2961 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2963 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2964 Port to ns-resolution time stamps.
2965 (EMACS_TIME_NEG_P): Remove; replaced by....
2966 (EMACS_TIME_SIGN): New macro.

2970 (make_timeval, make_lisp_time, decode_time_components): New decls.
2971 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2972 that it mishandled time_t overflow. You can't compare by subtracting!
2973 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2974 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2976 * term.c: Include <sys/time.h>.

2985 (w32_get_internal_run_time):
2986 Port to higher-resolution Emacs time stamps.
2987 (ltime): Now accepts single 64-bit integer, as that's more convenient
2990 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2992 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2993 for compatibility with pselect. Support ns-resolution time stamps.
2995 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2997 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2998 Check for time stamp overflow, and support ns-resolution time stamps.
3000 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3001 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3002 (timeval_subtract): Remove; no longer needed.
3003 (XTflash, XTring_bell, x_wait_for_event):
3004 Port to ns-resolution time stamps. Don't assume time_t is signed.
3006 2012-06-22 Chong Yidong <cyd@gnu.org>

3010 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3012 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3013 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3014 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3015 staticidx goes up to 1597 out of 1600 = 0x640.)
3017 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3019 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3020 Otherwise, the umask might be mistakenly 0 while handling input signals.

3054 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3055 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3056 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

3065 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3066 gets killed during executing of this function (Bug#11665).
3067 Try to always return Qt when the buffer has been actually killed.
3068 (Vkill_buffer_query_functions): In doc-string say that functions
3069 run by this hook should not change the current buffer.
3071 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3073 Fix recently-introduced process.c problems found by static checking.

3091 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3093 * lisp.h (eassert): Assume C89 or later.
3094 This removes the need for CHECK.
3095 (CHECK): Remove. Its comments about always evaluating its
3096 argument were confusing, as 'eassert' typically does not evaluate
3099 * coding.c (produce_chars): Use ptrdiff_t, not int.
3101 * xterm.c (x_draw_underwave): Check for integer overflow.
3102 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3268 * s/usg5-4-common.h, src/s/unixware.h:
3269 Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
3271 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
3273 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
3275 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
3276 * alloc.c (make_number) [!defined make_number]:
3277 Remove, as lisp.h always defines this now.
3278 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
3279 (roundup_size): Verify that it is a power of 2.
3280 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
3281 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
3282 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
3283 -DUSE_LSB_TAG=0, to override the automatically-selected default.
3284 USE_LSB_TAG now is always defined to be either 0 or 1.
3286 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3287 code works fine either way, and efficiency is not a concern here,
3288 as the union type is for debugging, not for production.
3289 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3290 Use an inline function on all platforms when using the union type,
3291 since this is simpler and 'static inline' can be used portably
3293 (LISP_INITIALLY_ZERO): New macro.
3294 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3295 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
3297 2012-06-12 Glenn Morris <rgm@gnu.org>
3299 * s/gnu-kfreebsd.h, s/hpux11.h, s/openbsd.h, s/sol2-10.h: Remove files.

3307 Move NO_TERMIO to configure.
3309 2012-06-12 Chong Yidong <cyd@gnu.org>
3311 * image.c (imagemagick_load_image): Use MagickFlattenImage if
3312 MagickMergeImageLayers is undefined. Use pixel pusher loop if
3313 MagickExportImagePixels is undefined.
3315 2012-06-12 Paul Eggert <eggert@cs.ucla.edu>
3317 * image.c (imagemagick_load_image): Remove unused label.
3319 2012-06-11 Glenn Morris <rgm@gnu.org>
3321 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
3322 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
3323 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
3324 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
3326 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
3328 * alloc.c (make_byte_code): New function.
3329 (Fmake_byte_code): Use it. Don't purify here.

3332 2012-06-11 Chong Yidong <cyd@gnu.org>
3334 * image.c (imagemagick_load_image): Implement transparency.
3336 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>

3339 account for preceding backslashes. (Bug#11663)
3341 2012-06-09 Chong Yidong <cyd@gnu.org>

3357 * dispextern.h: Replace unused TTY_CAP_BLINK with TTY_CAP_ITALIC.
3358 (struct face): Remove unused fields tty_dim_p, tty_blinking_p, and
3359 tty_alt_charset_p. Add tty_italic_p.
3361 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
3363 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
3364 dbus_type_is_basic if available.
3365 (xd_extract_signed, xd_extract_unsigned): Rename from
3366 extract_signed and extract_unsigned, respectively. Adapt callers.
3368 2012-06-09 Chong Yidong <cyd@gnu.org>
3370 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).
3372 * fringe.c (Fset_fringe_bitmap_face): Handle the noninteractive
3375 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
3377 * xdisp.c (vmessage): Treat frame message as multibyte.
3378 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
3379 would generate the diagnostic "Making \302\247 buffer-local while
3382 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3384 * dispnew.c (showing_window_margins_p): Undo last change, which

3395 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
3397 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
3398 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3400 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3402 * alloc.c (allocate_vectorlike): Fix last change.
3404 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
3406 Block-based vector allocation of small vectors.
3407 * lisp.h (struct vectorlike_header): New field `nbytes',
3408 adjust comment accordingly.
3409 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
3410 to denote vector blocks. Adjust users (live_vector_p,
3411 mark_maybe_pointer, valid_lisp_object_p) accordingly.
3412 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
3413 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
3414 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
3415 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
3416 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
3417 (roundup_size): New constant.

3431 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
3433 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3435 * doprnt.c (doprnt): Truncate multibyte char correctly.
3436 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3437 would mishandle a string argument "Xc" if X was a multibyte
3438 character of length 2: it would truncate after X's first byte
3439 rather than including all of X.
3441 2012-06-06 Chong Yidong <cyd@gnu.org>
3443 * buffer.c (word_wrap): Doc fix.
3445 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

3490 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3492 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3493 Convert pctcpu and pctmem to Lisp float properly.
3494 Let the compiler fold better, as 100.0/0x8000 is exact.
3496 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3498 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3501 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3503 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3505 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3507 For a 'struct window', replace some Lisp_Object fields to
3508 bitfields where appropriate, remove unused fields.
3509 * window.h (struct window): Remove unused 'last_mark_x' and
3510 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3511 change it's type from Lisp_Object to bitfield.
3512 Change type of 'force_start', 'optional_new_start',
3513 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3514 fields from Lisp_Object to bitfield. Adjust users accordingly.
3516 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3518 Pacify gcc -Wdouble-precision when using Xaw.
3519 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3520 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3521 Use 'float' consistently, rather than 'float' in most places
3522 and 'double' in a couple of places.
3524 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3526 * xdisp.c (handle_stop): Detect whether we have overlay strings
3527 loaded by testing it->current.overlay_string_index to be
3528 non-negative, instead of checking whether n_overlay_strings is
3529 positive. (Bug#11587)
3531 2012-05-31 Chong Yidong <cyd@gnu.org>
3533 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3535 * doc.c (Fsubstitute_command_keys): Doc fix.
3537 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3539 * search.c (search_buffer): Remove calls to
3540 r_alloc_inhibit_buffer_relocation, as it is now called by
3541 maybe_unify_char, which was the cause of relocation of buffer text
3544 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3546 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3547 for the duration of call to load_charset, to avoid problems with
3548 callers of maybe_unify_char that access buffer text through C
3551 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3552 decrement the inhibition flag, instead of just setting or
3555 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3557 Remove obsolete '#define static' cruft.
3558 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3559 This #undef was "temporary" in 2000; it is no longer needed
3560 now that '#define static' has gone away.
3561 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3562 (gray_bitmap_bits): Remove; no longer needed.
3563 All uses replaced with definiens.
3564 * xterm.c: Include "bitmaps/gray.xbm".
3566 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3568 Clean up __executable_start, monstartup when --enable-profiling.
3569 The following changes affect the code only when profiling.
3570 * dispnew.c (__executable_start): Rename from safe_bcopy.
3571 Define only on platforms that need it.
3572 * emacs.c: Include <sys/gmon.h> when profiling.
3573 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3574 (__executable_start): Remove decl, since lisp.h does it now.
3575 (safe_bcopy): Remove decl; no longer has that name.
3576 (main): Coalesce #if into single bit of code, for simplicity.
3577 Cast pointers to uintptr_t, since standard libraries want integers

3602 * lread.c (read1): Tiny simplification.
3604 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3606 Do not create empty overlays with the evaporate property (Bug#9642).
3607 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3608 Bug#9642, but explicitly check that the buffer the overlay would
3609 be moved to is live and rearrange lines to make sure that errors
3610 will not put the overlay in an inconsistent state.
3611 (Fdelete_overlay): Cosmetics.
3613 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3615 * w32term.c (my_bring_window_to_top): New function.
3616 (x_raise_frame): Use handle returned by DeferWindowPos, which
3617 could be different from the original one.

3621 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3622 by calling BringWindowToTop.

3627 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3629 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3630 This avoids undefined behavior that might cause the eassert
3631 to not catch an out-of-range value.
3633 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3635 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3647 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3649 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3650 Only r_alloc_inhibit_buffer_relocation needed to be added;
3651 the others were already declared.
3653 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3654 before checking whether it's out of range. Put the check inside
3656 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3658 2012-05-27 Ken Brown <kbrown@cornell.edu>
3660 * callproc.c (Fcall_process): Restore a line that was accidentally
3661 commented out in the 2011-02-13 change (bug#11547).

3665 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3666 defined on ralloc.c.
3668 * buffer.c [REL_ALLOC]: Remove prototypes of
3669 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3670 they are now on lisp.h.
3672 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3674 * search.c (search_buffer): Use it to inhibit relocation of buffer
3675 text while re_search_2 is doing its job, because re_search_2 is
3676 passed C pointers to buffer text. (Bug#11519)
3678 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3681 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3682 state after an additional call to move_it_in_display_line_to, keep
3683 the values of it->max_ascent and it->max_descent found for the
3685 (pos_visible_p): Revert the comparison against bottom_y to what it
3686 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3689 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3691 Fix coding-related core dumps with gcc -ftrapv.
3692 The code was computing A - B, where A and B are pointers, and B is
3693 random garbage. This can lead to core dumps on platforms that
3694 have special pointer registers, and it also leads to core dumps on
3695 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3696 A - B only when B is initialized properly.
3697 * coding.c (coding_set_source, coding_set_destination): Return void.
3698 (coding_change_source, coding_change_destinations): New functions,
3699 with the old behaviors of coding_set_source and coding_set_destination.
3700 All callers that need an offset changed to use these new functions.
3702 2012-05-26 Glenn Morris <rgm@gnu.org>
3704 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3706 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3708 Extend mouse support on W32 text-mode console.
3709 * xdisp.c (draw_row_with_mouse_face):
3710 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3712 * w32console.c: Include window.h.
3713 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3715 (initialize_w32_display): Initialize mouse-highlight data.
3717 * w32inevt.c: Include termchar.h and window.h.
3718 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3719 moves, call note_mouse_highlight. If help_echo changed, call
3720 gen_help_event to produce help-echo message in the echo area.
3721 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3724 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3726 * lread.c (read1): Simplify slightly to avoid an overflow warning
3727 with GCC 4.7.0 on x86-64.
3729 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3731 * bidi.c (bidi_mirror_char): Revert last change: an int is
3732 definitely wide enough here.
3734 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3736 Fix integer width and related bugs (Bug#9874).
3737 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3738 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3739 (string_bytes, check_sblock, allocate_string_data):
3740 (compact_small_strings, Fmake_bool_vector, make_string)
3741 (make_unibyte_string, make_multibyte_string)

3769 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3770 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3771 (validate_region): Omit unnecessary test for b <= e,
3772 since that's guaranteed by the previous test.
3773 (adjust_overlays_for_delete): Avoid pos + length overflow.
3774 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3775 (report_overlay_modification):

3777 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3786 not int, to avoid needless 32-bit limit on 64-bit hosts.
3787 (exec_byte_code): Use tighter memory-full test, one that checks
3788 for alloca overflow. Don't compute the address of the object just
3789 before an array, as that's not portable. Use EMACS_INT, not
3790 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3791 * callint.c (Fcall_interactively):
3792 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3805 (casify_object): Avoid integer overflow when overallocating buffer.
3806 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3809 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3810 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3813 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3814 For CCL_MapSingle, check that content and value are in int range.

3816 Check that Vcode_version_map_vector is a vector.
3817 (resolve_symbol_ccl_program): Check that vector header is in range.
3818 Always copy the vector, so that we can check its contents reliably
3819 now rather than having to recheck each instruction as it's being
3820 executed. Check that vector words fit in 'int'.
3821 (ccl_get_compiled_code, Fregister_ccl_program)
3822 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3823 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3825 contents are in range.
3826 (Fccl_execute_on_string): Check that status is in range.
3827 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3828 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3829 Accept and return EMACS_INT, not int, because callers can pass values

3838 avoid mishandling large integers.

3849 Don't rely on undefined behavior with signed left shift overflow.
3850 Don't assume unsigned int fits into fixnum, or that fixnum fits
3851 into unsigned int. Don't require max_code to be a valid fixnum;
3852 that's not true for gb10830 4-byte on a 32-bit host. Allow
3853 invalid_code to be a cons, for the same reason. Require code_offset
3854 to be a character. Avoid int overflow if max_char is close
3856 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3857 this is intended anyway and avoids some undefined behavior.
3858 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3859 INDEX_TO_CODE_POINT, as that's what it expects.
3860 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3861 * charset.h (DECODE_CHAR): Return int, not unsigned;
3862 this is what was intended anyway, and it avoids undefined behavior.
3863 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3864 integer-overflow issues.
3865 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3866 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3867 where the argument is EMACS_INT, and this behavior is not intended.
3868 * chartab.c (Fmake_char_table, Fset_char_table_range)
3869 (uniprop_get_decoder, uniprop_get_encoder):
3870 Don't assume fixnum fits in int.
3871 * cmds.c (move_point): New function, that does the gist of
3872 Fforward_char and Fbackward_char, but does so while checking
3873 for integer overflow more accurately.
3874 (Fforward_char, Fbackward_char): Use it.
3875 (Fforward_line, Fend_of_line, internal_self_insert)
3876 (internal_self_insert):
3877 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4536 2012-05-25 Glenn Morris <rgm@gnu.org>
4538 * lisp.mk (lisp): Update for more files being compiled now.
4540 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
4542 * lread.c: Remove `read_pure' which makes no difference.
4543 (read_pure): Remove var.
4544 (unreadpure): Remove function.
4545 (readevalloop): Don't call read_list with -1 flag.
4546 (read1, read_vector): Don't test read_pure any more.
4547 (read_list): Simplify.

4558 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
4560 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4563 This directory predates autoconf and is no longer needed nowadays.
4564 Move its few remaining bits of functionality to where they're needed.
4565 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

4571 * mem-limits.h (EXCEEDS_LISP_PTR):
4572 Use VAL_MAX, not VALBITS, in #if.
4573 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
4574 (EMACS_UINT): Define unconditionally now.
4575 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4576 (BITS_PER_EMACS_INT): New constants, replacing
4577 what used to be in config.h, but not useful in #if.
4578 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4579 define them any more.
4580 (VAL_MAX): New macro.
4582 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4583 BITS_PER_EMACS_INT, in #if.
4584 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4585 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4586 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4587 * s/ms-w32.h (DATA_START):
4588 Move here from removed file m/intel386.h.
4589 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4590 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4592 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4594 Assume C89 or later.
4595 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

4603 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4604 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4605 * xterm.c (input_signal_count): Assume volatile works.
4607 2012-05-21 Ken Brown <kbrown@cornell.edu>
4609 * xgselect.c (xg_select): Fix first argument in call to 'select'
4612 2012-05-20 Ken Brown <kbrown@cornell.edu>
4614 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4615 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4617 2012-05-19 Ken Brown <kbrown@cornell.edu>
4619 * xfns.c (x_in_use): Remove `static' qualifier.
4620 * xterm.h (x_in_use): Declare.
4621 * xgselect.c: Include xterm.h.
4622 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4623 and `display_arg' (bug#9754).
4625 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4627 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4629 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4630 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4632 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4634 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4636 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4637 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4639 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4640 reference to image_cache->refcount.
4641 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4643 2012-05-17 Juri Linkov <juri@jurta.org>
4645 * search.c (Fword_search_regexp, Fword_search_backward)
4646 (Fword_search_forward, Fword_search_backward_lax)
4647 (Fword_search_forward_lax): Move functions to isearch.el
4648 (bug#10145, bug#11381).
4650 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4652 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4654 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4656 * lread.c (init_obarray): Declare Qt and Qnil as special.
4658 2012-05-14 Glenn Morris <rgm@gnu.org>
4660 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4661 Put "libexec" before "bin", for the sake of init_callproc_1.
4663 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4665 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4667 * unexaix.c: Port to more-recent AIX compilers.
4668 (report_error, report_error_1, make_hdr, copy_sym)
4669 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4670 Make arguments const char *, not char *, to avoid violations of C
4671 standard and to fix some AIX warnings reported by Gilles Pion.
4673 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4675 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4676 already have overlays loaded.
4677 (handle_single_display_spec): Before returning without displaying
4678 fringe bitmap, synchronize the bidi iterator with the main display
4679 iterator, by calling iterate_out_of_display_property.
4680 (iterate_out_of_display_property): Detect buffer iteration by
4681 testing that it->string is a Lisp string.
4682 (get_next_display_element): When the current object is exhausted,
4683 and there's something on it->stack, call set_iterator_to_next to
4684 proceed with what's on the stack, instead of returning zero.
4685 (set_iterator_to_next): If called at the end of a Lisp string,
4686 proceed to consider_string_end without incrementing string
4687 position. Don't increment display vector index past the end of
4688 the display vector. (Bug#11417)
4689 (pos_visible_p): Don't report a position visible when move_it_to
4690 stopped at the last line of window, which happens to be scanned
4691 backwards by the bidi iteration. (Bug#11464)
4693 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4695 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4696 and right-margin display specs even if the spec is invalid or we
4697 are on a TTY, and thus unable to display on the fringes.
4698 That's because the text with the property will not be displayed anyway,
4699 so we need to signal to the caller that this is a "replacing"
4700 display spec. This fixes display when the spec is invalid or we
4703 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4705 * unexaix.c (make_hdr): Fix typo in prototype.
4706 This bug broke the build on AIX. Problem reported by Gilles Pion.
4708 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4710 * keyboard.c (kbd_buffer_get_event): Read special events also in
4711 batch mode. (Bug#11415)
4713 2012-05-12 Glenn Morris <rgm@gnu.org>
4715 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4717 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4719 * lisp.mk (lisp): Add newcomment.elc.
4721 2012-05-12 Glenn Morris <rgm@gnu.org>
4723 * Makefile.in (MKDIR_P): New, set by configure.
4724 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4726 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4728 Remove unused function hourglass_started.
4729 * dispextern.h (hourglass_started):
4730 * w32fns.c (hourglass_started):
4731 * xdisp.c (hourglass_started): Remove.
4733 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4735 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4736 Update dependencies.
4738 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4740 * xgselect.c (xg_select): Put maxfds+1 into a var.
4741 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4743 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4745 2012-05-10 Dave Abrahams <dave@boostpro.com>
4747 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4748 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4750 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4752 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4753 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4754 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4755 Initialize xd_registered_buses.
4757 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4759 Untag more efficiently if USE_LSB_TAG.
4760 This is based on a proposal by YAMAMOTO Mitsuharu in
4761 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4762 For an admittedly artificial (nth 8000 longlist) benchmark on
4763 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4764 Emacs's overall text size by 1%.
4765 * lisp.h (XUNTAG): New macro.
4766 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4767 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4768 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4769 * eval.c (Fautoload):
4770 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4771 * frame.h (XFRAME): Use XUNTAG.
4773 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4774 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4775 Remove unportable assumptions about print widths of types like
4777 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4778 intptr_t when converting between pointer and integer, to avoid GCC
4779 warnings about wrong width.
4781 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4783 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4784 stack for each reader_thread, instead of defaulting to 8MB
4785 determined by the linker. This avoids failures in creating
4786 subprocesses on Windows 7, see the discussion in this thread:
4787 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4789 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4791 Fix up display of the *Minibuf-0* buffer in the mini window.
4792 * keyboard.c (read_char): Don't clear the echo area if there's no
4794 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4795 contents of *Minibuf-0*) if there's no message displayed in its stead.
4797 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4799 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4802 2012-05-06 Chong Yidong <cyd@gnu.org>
4804 * lisp.mk (lisp): Update.
4806 2012-05-05 Jim Meyering <meyering@redhat.com>
4808 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4810 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4812 * data.c (PUT_ERROR): New macro.
4813 (syms_of_data): Use it. Add new error type `user-error'.
4814 * undo.c (user_error): New function.
4815 (Fprimitive_undo): Use it.
4816 * print.c (print_error_message): Adjust print style for `user-error'.
4817 * keyboard.c (user_error): New function.
4818 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4820 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4822 Do not limit current-time-string to years 1000..9999.
4823 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4824 (Fcurrent_time_string): Support any year that is supported by the
4825 underlying localtime representation. Don't use asctime, as it
4826 has undefined behavior for years outside the range -999..9999.
4828 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4830 Fix race conditions involving setenv, gmtime, localtime, asctime.
4831 Without this fix, interrupts could mess up code that uses these
4832 nonreentrant functions, since setting TZ invalidates existing
4833 tm_zone or tzname values, and since most of these functions return
4834 pointers to static storage.
4835 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4836 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4837 Grow the critical sections to include not just invoking
4838 localtime/gmtime, but also accessing these functions' results
4839 including their tm_zone values if any, and any related TZ setting.
4840 (format_time_string): Last arg is now struct tm *, not struct tm **,
4841 so that the struct tm is saved in the critical section.
4842 All callers changed. Simplify allocation of initial buffer, partly
4843 motivated by the fact that memory allocation needs to be outside
4844 the critical section.
4846 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4848 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4849 with RESET_INTERVAL.
4851 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4852 Remove duplicated buffer name initialization.
4854 2012-05-02 Jim Meyering <jim@meyering.net>
4856 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4858 * xfns.c (x_window): Use xstrdup (Bug#11375).
4860 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4862 * xdisp.c (pos_visible_p): If already at a newline from the
4863 display string before the 'while' loop, don't walk back the glyphs
4864 from it3.glyph_row. Solves assertion violation when the display
4865 string begins with a newline (egg.el). (Bug#11367)
4867 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4869 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4872 2012-05-01 Glenn Morris <rgm@gnu.org>
4874 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4875 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4876 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4877 All were removed before 23.1.
4879 * dispnew.c: Remove HAVE_LIBNCURSES test;
4880 it is always true on relevant platforms.
4882 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4883 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4885 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

4893 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4895 Do not avoid creating empty evaporating overlays (Bug#9642).
4896 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4897 That is, do not delete an evaporating overlay if it becomes
4898 empty after its bounds are adjusted to fit within its buffer.
4899 This fix caused other problems, and I'm reverting it until we get
4900 to the bottom of them.
4902 2012-04-27 Chong Yidong <cyd@gnu.org>
4904 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4906 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4908 * xdisp.c (pos_visible_p): If the window start position is beyond
4909 ZV, start the display from buffer beginning. Prevents assertion
4910 violation in init_iterator when the minibuffer window is scrolled
4913 * window.c (window_scroll_pixel_based): Likewise.
4915 2012-04-27 Chong Yidong <cyd@gnu.org>

4929 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4931 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4932 display element, check also the underlying string or buffer
4933 character. (Bug#11341)
4935 * w32menu.c: Include w32heap.h.
4936 (add_menu_item): If the call to AppendMenuW (via
4937 unicode_append_menu) fails, disable Unicode menus only if we are
4938 running on Windows 9X/Me.
4940 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4942 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4945 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4947 * keyboard.c (read_char): Don't wipe echo area for select window
4948 events: These might get delayed via `mouse-autoselect-window'

4953 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4954 manipulation of :loaded-from data.
4956 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4958 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4959 now a cons (bug#11311).
4961 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4963 Do not create empty overlays with the evaporate property (Bug#9642).
4964 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4965 if it becomes empty after its bounds are adjusted to fit within
4966 its buffer. Without this fix, in a nonempty buffer (let ((o
4967 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4968 yields an empty overlay that has the evaporate property, which is
4969 not supposed to happen.
4971 Fix minor GTK3 problems found by static checking.
4972 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

4992 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4993 (__malloc_size_t, __malloc_ptrdiff_t):

5006 Define using prototypes, not old style.
5007 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5008 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

5073 since the two debugging options are incompatible.
5074 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5076 (mem_init, mem_insert, mem_insert_fixup):
5077 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5086 * sysdep.c [__FreeBSD__]: Minor cleanups.
5087 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5088 Use Emacs indenting style more consistently. Avoid some casts.
5089 Use 'double' consistently rather than mixing 'float' and 'double'.
5091 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5093 * sysdep.c (list_system_processes, system_process_attributes):
5094 Add implementation for FreeBSD (Bug#5243).

5109 (print_object): Check for cycles even when print-circle is nil and
5110 print-gensym is t, but only check print_depth if print-circle is nil.
5112 2012-04-20 Chong Yidong <cyd@gnu.org>
5114 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5115 set the status to "failed" and ensure that sentinel is run.

5170 New extern decls, to avoid calling undeclared functions.
5171 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5172 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5173 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5174 (NEED_MEM_INSERT): New macro.
5175 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5176 Remove one incorrect comment and fix another.

5190 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5191 Remove decls. This fixes an "It stinks!".
5193 * alloc.c (which_symbols): Fix alignment issue / type clash.
5195 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5197 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5214 Remove definition of GC_MARK_STACK, since the default now works.
5215 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5216 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5217 no longer the default.
5218 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5220 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5222 * lread.c (lisp_file_lexically_bound_p):

5243 2012-04-11 Daniel Colascione <dancol@dancol.org>
5245 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5246 against is gone. It's better to use vfork now so that when Cygwin
5247 gains a new, working vfork, we use it automatically (bug#10398).
5249 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5251 * window.c (save_window_save): Obey window-point-insertion-type.

5270 being loaded (bug#10424).
5272 2012-04-09 Glenn Morris <rgm@gnu.org>
5274 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5275 not just in the obarray, before snarfing them. (Bug#11036)

5283 * process.h: Add integer `gnutls_handshakes_tried' member to
5286 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5287 Add convenience `GNUTLS_LOG2i' macro.
5289 * gnutls.c (gnutls_log_function2i): Convenience log function.
5290 (emacs_gnutls_read): Use new log functions,
5291 `gnutls_handshakes_tried' process member, and
5292 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5293 attempts per process (connection).
5295 2012-04-09 Chong Yidong <cyd@gnu.org>

5301 * callint.c (Finteractive, Fcall_interactively):
5302 * minibuf.c (Fread_variable): Callers changed.
5304 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5306 * xdisp.c (set_cursor_from_row): If the display string appears in
5307 the buffer at position that is closer to point than the position
5308 after the display string, display the cursor on the first glyph of
5309 the display string. Fixes cursor display when a 'display' text
5310 property immediately follows invisible text. (Bug#11094)
5312 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5314 composite.c: use 'double' consistently
5315 * composite.c (get_composition_id): Use 'double' consistently
5316 instead of converting 'float' to 'double' and vice versa; this is
5317 easier to understand and avoids a GCC warning.
5319 2012-04-09 Glenn Morris <rgm@gnu.org>

5344 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5345 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5346 objects, as mark_maybe_pointer will catch them otherwise.

5367 (init_libxml2_functions, libxml2_loaded_p): New functions.
5368 (parse_region): Call fn_xmlCheckVersion instead of using the macro

5393 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5394 macros related to unification of CJK characters. For the details,
5395 see the discussion following the message here:
5396 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5398 2012-04-04 Chong Yidong <cyd@gnu.org>
5400 * keyboard.c (Vdelayed_warnings_list): Doc fix.

5412 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5414 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5415 position we get to after a call to move_it_to fails the
5416 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5417 only if we wind up in a string from display property. (Bug#11063)
5419 * window.c (Fdelete_other_windows_internal): Invalidate the row
5420 and column information about mouse highlight, so that redisplay
5421 restores it after reallocating the glyph matrices. (Bug#7464)
5423 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5424 string comes from a `display' text property, use the buffer
5425 position of that property as if we actually saw that position in
5427 (move_it_by_lines): Remove the assertion that
5428 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5429 violated when there's a before-string at the beginning of a line.
5432 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5434 * xdisp.c (append_space_for_newline): If the default face was
5435 remapped, use the remapped face for the appended newline.
5436 (extend_face_to_end_of_line): Use the remapped default face for
5437 extending the face to the end of the line.
5438 (display_line): Call extend_face_to_end_of_line when the default
5439 face was remapped. (Bug#11068)
5441 2012-03-29 Eli Zaretskii <eliz@gnu.org>

5454 2012-03-26 Kenichi Handa <handa@m17n.org>
5456 * dispextern.h (struct glyph): Fix previous change. Change the
5457 bit length of glyphless.ch to 25 (Bug#11082).
5459 2012-03-26 Chong Yidong <cyd@gnu.org>
5461 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5462 (command_loop_1): Use it; inhibit selection update for
5463 handle-select-window too (Bug#8996).
5465 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5467 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5469 2012-03-25 Kenichi Handa <handa@m17n.org>
5471 * dispextern.h (struct glyph): Change the bit length of
5472 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5474 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5476 * s/ms-w32.h (tzname): Include time.h before redirecting to
5477 _tzname. Fixes the MSVC build. (Bug#9960)
5479 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5481 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5484 * xterm.c (XTread_socket): Only modify handling_signal if
5485 !SYNC_INPUT. (Bug#11080)
5487 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5489 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5490 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5491 when fetching a multibyte character consumes more bytes than
5492 CHAR_BYTES returns, due to unification of CJK characters in
5493 string_char. (Bug#11073)
5495 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5497 * process.c (wait_reading_process_output): Handle pty disconnect

5527 it fit in a valid range (Bug#11003).
5529 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5531 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5532 that is not from display property, accept the row as a "cursor
5533 row" if one of the string's character has a non-nil `cursor'
5534 property. Fixes cursor positioning when there are newlines in
5535 overlay strings, e.g. in icomplete.el. (Bug#11035)
5537 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

5543 * eval.c (inhibit_lisp_code): Rename from
5544 inhibit_window_configuration_change_hook; move from window.c.

5547 * window.c (run_window_configuration_change_hook)
5548 (syms_of_window): Callers changed.

5568 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5571 2012-03-03 Glenn Morris <rgm@gnu.org>
5573 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5575 2012-03-02 Eli Zaretskii <eliz@gnu.org>

5581 (redisplay_window): Pass to move_it_vertically the margin in
5582 pixels, not in screen lines.
5584 2012-03-02 Glenn Morris <rgm@gnu.org>
5586 * buffer.c (buffer-list-update-hook): Doc fix.
5588 2012-02-29 Eli Zaretskii <eliz@gnu.org>

5591 push_it before setting up the iterator for the first overlay
5592 string, even if we have an empty string loaded.
5593 (next_overlay_string): If there's an empty string on the iterator
5594 stack, pop the stack. (Bug#10903)
5596 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5598 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5599 Suggested by Stefan Monnier in
5600 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5601 * alloc.c (widen_to_Lisp_Object): New static function.
5602 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5603 and widening them to Lisp_Objects. This would work even if
5604 USE_LSB_TAG is defined and wide integers are used, which might
5605 happen in a future version of Emacs.
5607 2012-02-25 Chong Yidong <cyd@gnu.org>
5609 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5612 * xselect.c (Fx_selection_exists_p): Doc fix.
5613 (x_clipboard_manager_save_all): Print an informative message
5614 before saving to clipboard manager.
5616 2012-02-24 Chong Yidong <cyd@gnu.org>
5618 * keyboard.c (process_special_events): Handle all X selection

5646 when computing $valmask.
5648 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5649 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5650 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5651 It's useless in that case, and it can cause problems on hosts
5652 that allocate halves of EMACS_INT values separately.
5653 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5654 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5655 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5656 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5657 it avoids undefined behavior on hosts where shifting right by more
5658 than the word width has undefined behavior.
5660 2012-02-19 Chong Yidong <cyd@gnu.org>
5662 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5663 (Funhandled_file_name_directory, Ffile_name_as_directory)

5682 2012-02-15 Chong Yidong <cyd@gnu.org>
5684 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

5703 as that creates a dangerous corner case.
5705 * window.c (Fdelete_window_internal): Invalidate the mouse
5706 highlight (Bug#9904).
5708 2012-02-12 Glenn Morris <rgm@gnu.org>

5714 (Fx_disown_selection_internal, Fx_selection_exists_p)
5715 (Fx_selection_owner_p, Fx_get_selection_internal):
5716 Sync docs and argument specs with the xselect.c versions.

5744 2012-02-07 Glenn Morris <rgm@gnu.org>
5746 * image.c (Fimagemagick_types): Doc fix.
5748 * image.c (imagemagick-render-type): Change it from a lisp object

5781 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5783 Handle overflow when computing char display width (Bug#9496).
5784 * character.c (char_width): Return EMACS_INT, not int.
5785 (char_width, c_string_width): Check for overflow when
5786 computing the width; this is possible now that individual
5787 characters can have unbounded width. Problem introduced
5788 by merge from Emacs 23 on 2012-01-19.
5790 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

6352 * xdisp.c (redisplay_window): If cursor row is not fully visible
6353 after recentering, and scroll-conservatively is set to a large
6354 number, scroll window by a few more lines to make the cursor fully
6355 visible and out of scroll-margin. (Bug#10105)

6441 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6442 is set, removing the need for VIRT_ADDRESS_VARIES.
6443 (PURE_P): Use a more-efficient implementation that needs just one
6444 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6445 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6446 to 4 (xorl, subq, cmpq, setbe).
6447 * alloc.c (pure): Always extern now, since that's the
6448 VIRT_ADDR_VARIES behavior.
6449 (PURE_POINTER_P): Use a single comparison, not two, for
6450 consistency with the new puresize.h.
6451 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6458 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6459 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6460 behave as if the cursor position were at the window margin.
6462 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6463 and the cursor position is out of bounds, behave as if the cursor
6464 position were at the window margin. (Bug#10075)
6466 2011-11-18 Chong Yidong <cyd@gnu.org>
6468 * window.c (Fwindow_combination_limit): Make first argument

6490 compute_line_metrics.
6491 (compute_line_metrics): Call row_hash, instead of computing the
6494 * dispnew.c (verify_row_hash): Call row_hash for computing the
6495 hash code of a row, instead of duplicating code from xdisp.c.
6497 * dispextern.h (row_hash): Add prototype.
6499 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

6528 (Fset_window_configuration, save_window_save): Rename all
6529 occurrences of window_nest to window_combination_limit.
6531 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6533 * image.c (imagemagick_load_image): Fix typo.
6535 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6537 * xdisp.c (display_line): Move the call to
6538 highlight_trailing_whitespace before the call to
6539 compute_line_metrics, since the latter needs to see the final
6540 faces of all the glyphs to compute ROW's hash value.
6541 Fixes assertion violations in row_equal_p. (Bug#10035)
6543 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6545 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6550 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6551 with user-defined heap size. Bump the default size of the temacs
6552 heap to 27MB, to avoid memory warning when running temacs.
6553 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6555 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6602 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6604 Avoid some portability problems by eschewing 'extern inline' functions.
6605 The trivial performance wins aren't worth the portability hassles; see
6606 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6608 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6610 (window_box_right, window_box_right_offset): Undo previous change,
6611 by removing the "extern"s.
6612 * intervals.c (adjust_intervals_for_insertion)
6613 (adjust_intervals_for_deletion): Undo previous change,
6614 making these static again.
6615 (offset_intervals, temp_set_point_both, temp_set_point)
6616 (copy_intervals_to_string): No longer inline.
6617 * xdisp.c (window_text_bottom_y, window_box_width)

6683 (window_box_right, window_box_right_offset): Declare extern.
6684 Otherwise, these inline functions do not conform to C99 and
6685 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6686 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6687 * intervals.c (adjust_intervals_for_insertion)
6688 (adjust_intervals_for_deletion): Now extern, because otherwise the
6689 extern inline functions 'offset_intervals' couldn't refer to it.
6690 (static_offset_intervals): Remove.
6691 (offset_intervals): Rewrite using the old contents of
6692 static_offset_intervals. The old version didn't conform to C99
6693 because an extern inline function contained a reference to an
6694 identifier with static linkage.
6696 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6698 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6716 (Fwindow_vscroll): Doc fix.
6717 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6718 argument, since it makes no sense to pass a live window and for
6719 consistency with window-child.

6747 (unwind_create_frame): New function (Bug#9943).
6748 (Fx_create_frame): Restructure code to be more similar to the one in
6749 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6750 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6751 Move terminal->reference_count++ just before making the frame official

6759 Move terminal->reference_count++ just before making the frame
6760 official. Move initialization of image_cache_refcount and
6761 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

6788 [_MSC_VER]: Include sys/timeb.h, sys/stat.h, and signal.h.
6789 (fstat, stat, utime) [_MSC_VER]: Redirect to their sys_* cousins.
6790 (malloc, free, realloc, calloc) [_MSC_VER]: Always redirect to the
6792 (alloca) [_MSC_VER]: Define to _alloca.
6794 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
6796 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
6798 2011-11-04 Eli Zaretskii <eliz@gnu.org>
6800 * xdisp.c (note_mouse_highlight): If either of
6801 previous/next-single-property-change returns nil, treat that as
6802 the beginning or the end of the buffer. (Bug#9955)
6804 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6806 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

6822 * xfns.c (unwind_create_frame): Likewise.
6824 2011-11-01 Eli Zaretskii <eliz@gnu.org>
6826 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6827 Don't stop backward scan on the continuation glyph, even though
6828 its CHARPOS is positive.
6829 (mouse_face_from_buffer_pos, note_mouse_highlight):
6830 Rename cover_string to disp_string.
6832 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6834 * window.c (temp_output_buffer_show): Don't use
6835 Vtemp_buffer_show_specifiers.
6836 (Vtemp_buffer_show_specifiers): Remove unused variable.
6838 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6840 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6841 past the beginning of the current glyph matrix.
6843 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
6845 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
6846 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6847 HAVE_GTK3 (Bug#9869).
6849 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6850 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6852 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6854 * xterm.c: Declare x_handle_net_wm_state to return int.

6863 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6865 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6866 so that this new function doesn't get optimized away by a
6867 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6869 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6871 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6873 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6875 Fix the `xbytecode' command.
6876 * .gdbinit (xprintbytestr): New command.
6877 (xwhichsymbols): Rename from `which'; all callers changed.
6878 (xbytecode): Print the byte-code string as well.
6880 2011-10-29 Kim Storm <storm@cua.dk>
6882 * alloc.c (which_symbols): New function.
6884 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6886 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6889 2011-10-29 Glenn Morris <rgm@gnu.org>
6891 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6892 Not clear what it was for, and it causes various bugs. (Bug#9839)
6894 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6896 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6897 possible random value that matches one of those tested as
6898 condition to clear the mouse face.
6900 2011-10-28 Chong Yidong <cyd@gnu.org>
6902 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6904 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6906 * window.c (make_window): Initialize phys_cursor_on_p.
6908 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6910 * lisp.h (struct Lisp_Symbol): Update comments.
6912 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6914 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6916 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6918 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6919 <oslsachem@gmail.com> for helping to debug this.
6921 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6922 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6923 (g_b_init_get_glyph_outline_w): New static variables.
6924 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6925 (GetGlyphOutlineW_Proc): New typedefs.
6926 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6927 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6929 (w32font_open_internal, compute_metrics):
6930 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6931 instead of calling the "wide" APIs directly.
6933 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6935 * w32.h (syms_of_w32font): Add prototype.
6937 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6939 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6940 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6941 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6942 (Fmove_to_window_line): Doc fix.
6944 2011-10-27 Chong Yidong <cyd@gnu.org>
6946 * process.c (make_process): Set gnutls_state to NULL.
6948 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6949 non-NULL, regardless of GNUTLS_INITSTAGE.
6950 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6951 an error. Set process slots as soon as we allocate them.
6953 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6955 2011-10-27 Chong Yidong <cyd@gnu.org>

6961 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6962 (deactivate_process): Call emacs_gnutls_deinit.
6964 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6968 * w32font.c (fill_in_logfont):
6969 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6971 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6973 * w32fns.c (w32_default_color_map): New function,
6974 extracted from Fw32_default_color_map.
6975 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6977 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6979 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6981 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6983 * keyboard.c (test_undefined): New function (bug#9751).
6984 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6986 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6988 * sysdep.c (init_sys_modes): Fix the check for the controlling
6989 terminal (Bug#6649).
6991 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6993 * dispextern.h (struct bidi_it): New member next_en_type.
6995 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6996 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6997 current character, check also for next_en_type being WEAK_EN.
6998 (bidi_resolve_weak): Don't enter the expensive loop if the current
6999 position is before next_en_pos. Record the bidi type of the first
7000 non-ET, non-BN character we find, in addition to its position.
7001 (bidi_level_of_next_char): Invalidate next_en_type when
7002 next_en_pos is over-stepped.
7004 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7006 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7007 * editfns.c: Rewrite current-time-zone so that it invokes
7008 the equivalent of (format-time-string "%Z") to get the time zone name.
7009 This fixes a bug when the time zone name contains characters that
7010 need converting from the system time locale to Emacs internal format.
7011 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7012 that patch fixed format-time-string to do the conversion, but
7013 I forgot to fix current-time-zone.
7014 (format_time_string): New function, containing most of
7015 what Fformat_time_string used to contain.
7016 (Fformat_time_string): Rewrite in terms of format_time_string.
7017 This doesn't change this function's behavior.
7018 (current-time-zone): Rewrite to use format_time_string.
7019 This fixes the bug reported by Michael Schierl in
7020 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7021 Jason Rumney's 2007-06-07 change worked around this bug, but
7023 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7025 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7027 * xdisp.c (start_display): If the character at POS is displayed
7028 via a display vector, reset IT->current.dpvec_index to zero.
7029 (try_window_reusing_current_matrix): If a line ends in a display
7030 vector or the next line starts in a display vector, continue
7031 redrawing the window even though the character position of
7032 start_row was reached.
7035 2011-10-18 Chong Yidong <cyd@gnu.org>
7037 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7038 with nobreak-char-display too.
7040 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7042 Fix part 3 of bug#9771.
7043 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7044 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7045 non-neutral characters if the current character is a paragraph
7046 separator (a.k.a. Newline). This avoids running the same
7047 expensive loop twice, once when we consume the preceding newline
7048 and the other time when the line actually needs to be displayed.
7049 Avoid the loop when we see neutrals on the base embedding level
7050 following a character whose directionality is the same as the
7051 paragraph's. This avoids running the expensive loop when a line
7052 ends in a long sequence of neutrals, like control characters.
7053 Add assertion against STRONG_AL type. Slightly rearrange code
7054 that determines the type of a neutral given the first non-neutral
7056 (bidi_level_of_next_char): Set next_en_pos to zero when
7057 invalidating its info.
7059 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7061 * xdisp.c (push_display_prop): Determine whether to record string
7062 or buffer position by IT->string, not by IT->method. Allow
7063 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7064 (move_it_vertically_backward): Don't look for character position
7065 immediately after the newline when in a continuation line.
7068 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7070 * window.c (coordinates_in_window): Rewrite and delabelize
7071 vertical border check. (Bug#5357) (Bug#9618)
7073 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7075 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7076 errors in XSetWindowBorder (bug#9310).
7078 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7080 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7081 avoid crash when xmalloc overrun checking is enabled.
7083 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7085 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7086 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7087 cursor motion with <left> and <right> arrow keys.
7089 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7090 some callers set that themselves.
7092 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7094 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7095 display string and the previous row comes from the same string and
7096 is empty. (Bug#9739) (Bug#9738)
7098 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7100 * doc.c (get_doc_string): Encode file name (bug#9735).
7102 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7104 * bidi.c (bidi_level_of_next_char):
7105 * xdisp.c (get_visually_first_element): Remove old incorrect
7106 comments regarding the Unicode Line Separator character.
7108 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7110 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7112 * alloc.c (Fgc_status): Do not access beyond zombies array
7113 boundary if nzombies > MAX_ZOMBIES.
7114 * alloc.c (dump_zombies): Add missing format specifier.
7116 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7118 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7119 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7121 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7122 Some packages use them to denote characters with modifiers.
7124 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7126 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7127 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7128 matching a pp-number. Rename parameter var to var1.
7130 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7132 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7134 2011-10-08 Glenn Morris <rgm@gnu.org>
7136 * callint.c (Fcall_interactively): Give a more explicit error for the
7137 'c' case with a non-character input. (Bug#8479)
7139 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7141 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7143 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7144 lines that are hscrolled on the left.
7146 * dispnew.c (buffer_posn_from_coords): Account for a possible
7147 presence of header-line. (Bug#4426)
7149 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7151 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7152 Don't advertise functionality which we discourage or doesn't work.
7154 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7156 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7157 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7158 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7159 this makes Emacs dump core during garbage collection on rare
7160 occasions. sizeof is obviously inferior to offsetof here, so
7161 stick with offsetof.
7162 (GC_POINTER_ALIGNMENT): New macro.
7163 (mark_memory): Omit 3rd (offset) arg; caller changed.
7164 Don't assume EMACS_INT alignment is the same as pointer alignment.
7166 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7168 * keyboard.c (read_key_sequence_remapped): New var.
7169 (read_key_sequence): Compute remapping in the right buffer.
7170 (command_loop_1): Use read_key_sequence's remapping directly.
7172 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7174 * dired.c (file_name_completion): Don't expand file name.
7175 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7176 before checking file name handler.
7178 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7179 they've been requested explicitly (bug#9591).
7181 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7183 * keymap.c (Fsingle_key_description): Use make_specified_string
7184 instead of build_string to build string from push_key_description.
7187 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7189 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7190 This fixes a Y2038 bug on 64-bit hosts.
7191 * buffer.c (reset_buffer):
7192 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7193 (Fclear_buffer_auto_save_failure):
7194 Use 0, not -1, to represent an unset failure time, since time_t
7195 might not be signed.
7197 Remove dependency on glibc malloc internals.
7198 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7199 Move back here from lisp.h, but with their new implementations.
7200 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7201 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7202 * charset.c (charset_table_init): New static var.
7203 (syms_of_charset): Use it instead of xmalloc. This removes a
7204 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7205 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7206 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7207 Move back to alloc.c.
7208 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7209 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7211 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7213 * nsterm.m (windowDidResize): Call x_set_window_size only when
7214 ns_in_resize is true. Otherwise set pixelwidth/height and
7215 call change_frame_size (Bug#9628).
7217 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7219 Port --enable-checking=all to Fedora 14 x86-64.
7220 * charset.c (syms_of_charset): Also account for glibc malloc's
7221 internal overhead when calculating the initial malloc maximum.
7223 Port --enable-checking=all to Fedora 14 x86.
7224 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7226 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7227 (overrun_check_realloc, overrun_check_free):
7228 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7229 That way, xmalloc returns a properly-aligned pointer even if
7230 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7231 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7232 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7233 into account when calculating the initial malloc maximum.
7234 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7235 Move here from alloc.c, so that charset.c can use it too.
7236 Properly align; the old code wasn't right for common 32-bit hosts
7237 when configured with --enable-checking=all.
7238 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7239 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7241 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7243 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,

7248 * xdisp.c (compute_display_string_end): If there's no display
7249 string at CHARPOS, return -1.
7251 * bidi.c (bidi_fetch_char): When compute_display_string_end
7252 returns a negative value, treat the character as a normal
7253 character not covered by a display string. (Bug#9624)
7255 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7257 * lread.c (Fread_from_string): Fix typo in docstring.
7259 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7261 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7262 newline, reseat the iterator instead of bidi-iterating there one
7263 character at a time. (Bug#9610)
7264 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7265 TO_CHARPOS if the bidi iterator is at base embedding level.
7267 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7269 * lread.c (readevalloop): Use correct code for NBSP.

7275 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7277 2011-09-25 Glenn Morris <rgm@gnu.org>
7279 * buffer.c (truncate-lines): Doc fix.
7281 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

7296 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7298 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7299 Default value is now t. Doc fix.
7301 * indent.c (Fvertical_motion): Compute and apply the overshoot
7302 logic when moving up, not only when moving down. Fix the
7303 confusing name and values of the it_overshoot_expected variable;
7304 logic changes accordingly. (Bug#9254) (Bug#9549)
7306 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7307 CHARPOS is covered by a display string which includes newlines.
7308 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7309 is covered by a display string with embedded newlines.
7311 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7313 * dbusbind.c (Fdbus_register_signal): Add match rule to
7314 Vdbus_registered_objects_table. (Bug#9581)
7315 (Fdbus_register_method, Vdbus_registered_objects_table):
7318 2011-09-24 Jim Meyering <meyering@redhat.com>
7320 do not ignore write error for any output size
7321 The previous change was incomplete.
7322 While it makes emacs --batch detect the vast majority of stdout
7323 write failures, errors were still ignored whenever the output size is
7324 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7325 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7326 && echo FAIL: ignored write error
7327 FAIL: ignored write error
7328 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7329 && echo FAIL: ignored write error
7330 FAIL: ignored write error

7333 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7335 * emacs.c (Fkill_emacs): In noninteractive mode exit
7336 non-successfully if a write error occurred on stdout. (Bug#9574)
7338 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7340 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7343 * dispextern.h (struct it): Update the comment documenting what
7346 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7348 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7349 a display string, extend search for cursor position to end of row.
7350 (find_row_edges): If the row ends in a newline from a display
7351 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7352 Handle the case of a display string with multiple newlines.
7353 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7354 non-empty line. Fixes confusing cursor motion with arrow keys at
7355 the beginning of a line that starts with whitespace.
7357 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7359 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is

7364 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7367 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7369 * xdisp.c (display_line): Record maximum and minimum buffer
7370 positions even if no glyphs were produced (e.g., by a zero-width
7371 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7372 buffer positions that will be removed from the glyph row because
7374 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7375 column is beyond frame width: don't subtract 1 "pixel" when
7376 computing width of the stretch.
7377 (reseat_at_next_visible_line_start): Undo the change made on
7378 2011-09-17 that saved paragraph information and restored it after
7379 the call to `reseat'. (Bug#9545)
7381 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7383 * xdisp.c (expose_window): Save original value of phys_cursor_on_p

7395 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7397 Fix minor problem found by static checking.
7398 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7399 initialized, to pacify gcc -Wuninitialized.
7401 * fileio.c: Report proper errno when syscall falls.
7402 (Finsert_file_contents): Save and restore errno,
7403 so that report_file_error outputs the correct diagnostic.
7404 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7406 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7408 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7410 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7412 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7413 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7415 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7417 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7418 about the current paragraph and restore it after the call to reseat.
7420 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7421 (bidi_find_paragraph_start): Search back for paragraph beginning
7422 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7423 (bidi_move_to_visually_next): Only trigger paragraph-related
7424 computations when the last character is a newline or at EOB, not
7425 just any NEUTRAL_B. (Bug#9470)
7427 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7428 truncated lines if point is covered by a display string. (Bug#9524)
7430 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7432 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7433 (cons_to_x_long): New function.
7434 (lisp_data_to_selection_data): Use it. Correct the test for
7435 short-versus-long data; it was negated. Break out of vector
7436 loop, for efficiency, when a long datum is discovered.
7438 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7440 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7442 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7444 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7445 GCC PR/17406) by declaring this function with external scope.
7447 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7449 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

7452 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7454 * editfns.c (Fformat): Correctly handle text properties on "%%".

7464 of TAB characters in a composition.
7466 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7468 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7469 This occurs when processing a multibyte format.
7470 Problem reported by Wolfgang Jenker.
7472 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7474 * xdisp.c (try_cursor_movement): Only check for exact match if
7475 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7477 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7479 Remove unused external symbols.
7480 * dispextern.h (calc_pixel_width_or_height): Remove decl.

7483 * indent.c (check_display_width):
7484 * w32term.c: Fix comment to match code.
7485 * xterm.c, xterm.h (x_catching_errors): Remove.
7487 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7489 * xselect.c: Use signed conversions more consistently (Bug#9498).
7490 (selection_data_to_lisp_data): Assume incoming selection data are
7491 signed integers, not unsigned. This is to be consistent with
7492 outgoing selection data, which was modified to use signed integers
7493 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7494 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7495 expects long, not unsigned long.
7497 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7499 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7500 computation of loop end. Reported by Johan Bockgård
7503 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7505 * frame.c (Fother_visible_frames_p): Function deleted.
7507 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7509 * indent.c (compute_motion): Process display vector front to back
7510 rather than the other way around. (Bug#2496)
7512 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7514 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7516 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7518 * minibuf.c (Fread_from_minibuffer): Doc fix.
7520 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7522 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7523 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7525 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7527 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7528 value for non-existent files.
7530 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7532 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7533 set its "size" to -1. This will set the modtime_size field of
7534 the corresponding buffer to -1, which is what
7535 verify-visited-file-modtime expects for files that do not exist.
7538 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7540 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7542 * lisp.h: ... from here. push_key_description is no longer
7543 defined in keyboard.c, so its declaration should not be in
7544 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7545 logically belongs with push_key_description.
7547 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7549 * buffer.h: Include <sys/types.h> instead of <time.h>.
7550 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7551 Problem reported by Herbert J. Skuhra.
7553 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7555 * xml.c (parse_region): Make the parsing work for
7556 non-comment-starting XML files again (bug#9144).
7558 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7560 * image.c (gif_load): Fix calculation of bottom and right corner.
7563 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7565 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7566 redisplay in small windows.
7568 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7570 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7572 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7574 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7575 Operate on live windows only.
7577 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7579 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7581 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7583 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7584 only under bidi iteration.
7586 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7588 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7590 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7592 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7593 Without this fix, the command to link temacs failed due to an
7594 undefined symbol __builtin_isnan. This is because
7595 /usr/include/iso/math_c99.h #defines isnan(x) to
7596 __builtin_isnan(x), but the bundled gcc, which identifies itself
7597 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7599 * floatfns.c (isnan): #undef, and then #define to a clone of
7601 (Fisnan): Always define, since it's always available now.
7602 (syms_of_floatfns): Always define isnan at the Lisp level.
7604 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7606 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7608 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7610 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7611 The previous code assumed that file offsets (off_t values) fit in
7612 EMACS_INT variables, which is not true on typical 32-bit hosts.
7613 The code messed up by falsely reporting buffer overflow in cases
7614 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7615 when "big" contains more than 2**29 bytes, even though this
7616 inserts just one byte and does not overflow the buffer.
7617 (Finsert_file_contents): Store file offsets as off_t
7618 values, not as EMACS_INT values. Check for overflow when
7619 converting between EMACS_INT and off_t. When checking for
7620 buffer overflow or for overlap, take the offsets into account.
7621 Don't use EMACS_INT for small values where int suffices.
7622 When checking for overlap, fix a typo: ZV was used where
7623 ZV_BYTE was intended.
7624 (Fwrite_region): Don't assume off_t fits into 'long'.
7625 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7627 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7629 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7631 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7633 sprintf-related integer and memory overflow issues (Bug#9412).
7635 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7636 (esprintf, exprintf, evxprintf): New functions.
7637 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7638 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7639 (modify_event_symbol): Do not assume that the length of
7640 name_alist_or_stem is safe to alloca and fits in int.
7641 (Fexecute_extended_command): Likewise for function name and binding.
7642 (Frecursion_depth): Wrap around reliably on integer overflow.
7643 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7644 since some callers pass EMACS_INT values.
7645 (Fsingle_key_description): Don't crash if symbol name contains more
7646 than MAX_ALLOCA bytes.
7647 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7648 (get_minibuffer): Arg is now EMACS_INT, not int.
7649 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7650 (esprintf, exprintf, evxprintf): New decls.
7651 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7653 * dbusbind.c (signature_cat): New function.
7654 (xd_signature, Fdbus_register_signal):
7655 Do not overrun buffer; instead, report string overflow.
7657 * dispnew.c (add_window_display_history): Don't overrun buffer.
7658 Truncate instead; this is OK since it's just a log.
7660 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7661 even if the time zone offset is outlandishly large.
7662 Don't mishandle offset == INT_MIN.
7664 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7665 when creating daemon; the previous buffer-overflow check was incorrect.
7667 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7668 which has the guts of the old verror function.
7670 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7671 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7673 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7674 (font_unparse_xlfd): Don't blindly alloca long strings.
7675 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7676 fits in int, when using sprintf. Use single snprintf to count
7677 length of string rather than counting it via multiple sprintfs;
7678 that's simpler and more reliable.
7679 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7680 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7681 sprintf, in case result does not fit in int.
7683 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7684 (fontset_from_font): Print it.
7686 * frame.c (tty_frame_count): Now printmax_t, not int.
7687 (make_terminal_frame, set_term_frame_name): Print it.
7688 (x_report_frame_params): In X, window IDs are unsigned long,
7689 not signed long, so print them as unsigned.
7690 (validate_x_resource_name): Check for implausibly long names,
7691 and don't assume name length fits in 'int'.
7692 (x_get_resource_string): Don't blindly alloca invocation name;
7693 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7696 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7697 (xg_check_special_colors, xg_set_geometry):
7698 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7700 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7701 Use esprintf, not sprintf, in case result does not fit in int.
7703 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7704 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7705 it as a large positive number.
7706 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7707 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7709 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7710 in case result does not fit in int.
7712 * print.c (float_to_string): Detect width overflow more reliably.
7713 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7714 buffer overrun. Don't assume list length fits in 'int'. Treat
7715 print length of 0 as 0, not as infinity; to be consistent with other
7716 uses of print length in this function. Don't overflow print length
7717 index. Don't assume hash table size fits in 'long', or that
7718 vectorlike size fits in 'unsigned long'.
7720 * process.c (make_process): Use printmax_t, not int, to format
7721 process-name gensyms.
7723 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7725 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7726 to avoid potential buffer overrun.
7728 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7729 if X resource line is longer than 512 bytes.
7731 * xfns.c (x_window): Make sprintf buffer a bit bigger
7732 to avoid potential buffer overrun.
7734 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7738 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7740 Integer overflow fixes for scrolling, etc.
7741 Without these, Emacs silently mishandles large integers sometimes.
7742 For example, "C-u 4294967297 M-x recenter" was treated as if
7743 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7745 * xdisp.c (try_window_id): Check Emacs fixnum range before
7746 converting to 'int'.
7748 * window.c (window_scroll_line_based, Frecenter):
7749 Check that an Emacs fixnum is in range before assigning it to 'int'.
7750 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7751 values converted from Emacs fixnums.
7752 (Frecenter): Don't wrap around a line count if it is out of 'int'
7753 range; instead, treat it as an extreme value.
7754 (Fset_window_configuration, compare_window_configurations):
7755 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7757 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7758 that can exceed INT_MAX. Check that EMACS_INT value is in range
7759 before assigning it to the (possibly-narrower) index.
7760 (match_limit): Don't assume that a fixnum can fit in 'int'.
7762 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7765 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7766 (Fvertical_motion): Don't wrap around LINES values that don't fit
7767 in 'int'. Instead, treat them as extreme values. This is good
7768 enough for windows, which can't have more than INT_MAX lines anyway.
7770 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7772 * Require libxml/parser.h to avoid compilation warning.
7774 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7776 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7777 since this reportedly can destroy thread storage.
7779 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7781 * syntax.c (find_defun_start): Update all cache variables if
7782 exiting early (Bug#9401).
7784 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7786 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7788 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7789 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7790 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7792 * term.c (tty_append_glyph): New function.
7793 (produce_stretch_glyph): Static function and its prototype deleted.
7795 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7798 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7800 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7801 when checking :margin (Bug#9390).
7802 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7803 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7804 so that the name doesn't mislead. All uses changed.
7806 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7808 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7811 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7813 * xdisp.c (move_it_to): Don't bail out early when reaching
7814 position beyond to_charpos, if we are scanning backwards.
7815 (move_it_vertically_backward): When DY == 0, make sure we get to
7816 the first character in the line after the newline.
7818 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7820 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7821 (ccl_driver): Do not generate an out-of-range pointer.
7822 (Fccl_execute_on_string): Remove unnecessary check for
7823 integer overflow, noted by Stefan Monnier in
7824 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7825 Remove a FIXME that didn't need fixing.
7826 Simplify the newly-introduced buffer reallocation code.
7828 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7830 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7832 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7834 Integer and memory overflow issues (Bug#9196).
7836 * doc.c (get_doc_string): Rework so that
7837 get_doc_string_buffer_size is the actual buffer size, rather than
7838 being 1 less than the actual buffer size; this makes xpalloc more
7841 * image.c (x_allocate_bitmap_record, cache_image):
7842 * xselect.c (Fx_register_dnd_atom):
7843 Simplify previous changes by using xpalloc.
7845 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7846 since either will do and ptrdiff_t is convenient with xpalloc.
7848 * charset.c (charset_table_size)
7849 (struct charset_sort_data.priority): Now ptrdiff_t.
7850 (charset_compare): Don't overflow if priorities differ greatly.
7851 (Fsort_charsets): Don't assume list length fits in int.
7852 Check for size-calculation overflow when allocating sort data.
7853 (syms_of_charset): Allocate an initial charset table that is
7854 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7856 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7858 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7859 The actual value is always <= INT_MAX, and leaving it unsigned made
7860 overflow checking harder.
7862 * dispextern.h (struct glyph_matrix.rows_allocated)
7863 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7864 with xpalloc. The values are still always <= INT_MAX.
7866 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7868 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7869 (SAFE_NALLOCA): New macro.
7871 * region-cache.c (struct boundary.pos, find_cache_boundary)
7872 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7873 (set_cache_region, invalidate_region_cache)
7874 (revalidate_region_cache, know_region_cache, region_cache_forward)
7875 (region_cache_backward, pp_cache):
7876 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7877 so that ptrdiff_t * can be passed to xpalloc.
7878 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7879 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7880 (pp_cache): Don't assume cache_len fits in int.
7881 * region-cache.h: Adjust extern decls to match.
7883 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7884 EMACS_INT, since either will do, for xpalloc.
7886 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7887 (xnmalloc, xnrealloc, xpalloc): New functions.
7889 * bidi.c (bidi_shelve_header_size): New constant.
7890 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7891 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7893 * bidi.c (bidi_cache_shrink):
7894 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7896 Don't update size of array until after memory allocation succeeds,
7897 because xmalloc/xrealloc may not return.
7898 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7899 now that we have proper integer overflow checking.
7900 (record_overlay_string, overlay_strings): Catch overflows when
7901 calculating size of overlay_str_buf.
7903 * callproc.c (Fcall_process): Check for size overflow when
7904 calculating size of args2.
7905 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7906 Normally we prefer signed values, but sticking with ptrdiff_t would
7907 require adding more-complicated checks.
7909 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7910 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7911 Redo buffer-overflow calculations to avoid integer overflow.
7912 Add a FIXME comment where memory seems to be over-allocated.
7914 * character.c (Fstring): Check for size-calculation overflow.
7916 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7917 unnecessary integer overflow. Check for size overflow.
7918 (encode_coding_object): Don't update size until xmalloc succeeds.
7920 * composite.c (get_composition_id): Check for overflow in glyph
7921 length calculations.
7923 Integer and memory overflow fixes for display code.
7924 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7925 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7926 (scrolling_window): Check for overflow in size calculations.
7927 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7938 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7939 (get_doc_string): Check for size calculation overflow.
7940 Don't update size until allocation succeeds.
7941 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7942 EMACS_INT, where ptrdiff_t will do.
7943 (Fsubstitute_command_keys): Check for string overflow.
7945 * editfns.c (set_time_zone_rule): Don't assume environment length
7947 (message_length): Now ptrdiff_t, not int.
7948 (Fmessage_box): Don't update size until allocation succeeds.
7949 Don't assume message length fits in int.
7950 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7952 * emacs.c (main): Do not reallocate argv, since there is a null at
7953 the end that can be overwritten, and this way there's no need to
7954 worry about size-calculation overflow.
7955 (sort_args): Check for size-calculation overflow.
7957 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7959 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7961 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7962 (x_set_scroll_bar_width, x_figure_window_size):
7963 Check for integer overflow.
7964 (x_set_alpha): Do not assume XINT fits in int.
7966 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7967 This is for the members text_lines, text_cols, total_lines, total_cols,
7968 where the system imposes an 'int' limit.
7970 * fringe.c (Fdefine_fringe_bitmap):
7971 Don't update size until alloc works.
7973 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7974 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7976 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7977 Check for size-calculation overflow.
7978 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7979 do, as we prefer signed integers.
7980 (id_to_widget.max_size, id_to_widget.used)
7981 (xg_store_widget_in_map, xg_remove_widget_from_map)
7982 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7983 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7984 Use and return ptrdiff_t, not int.
7985 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7986 * gtkutil.h: Change prototypes to match the above.
7988 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7989 are duplicate now that they've been promoted to lisp.h.
7990 (x_allocate_bitmap_record, x_alloc_image_color)
7991 (make_image_cache, cache_image, xpm_load):
7992 Don't update size until alloc is done.

7995 Check for size calculation overflow.
7996 (ct_colors_allocated_max): New constant.

8002 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8003 Use ptrdiff_t, not int, to count maps.
8004 (read_char_minibuf_menu_prompt): Check for overflow in size
8005 calculations. Don't update size until allocation succeeds.

8016 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
8017 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8019 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8020 Now ptrdiff_t, not int.
8021 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8022 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
8024 * process.c (Fnetwork_interface_list): Check for overflow
8025 in size calculation.
8027 * region-cache.c (move_cache_gap): Check for size calculation overflow.

8032 * search.c (Freplace_match): Check for size calculation overflow.
8033 (Fset_match_data): Don't assume list lengths fit in 'int'.
8035 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8036 for command line length. Do not attempt to address one before the
8037 beginning of an array, as that's not portable.

8040 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8042 (encode_terminal_code, calculate_costs): Check for size
8043 calculation overflow.

8045 table lengths and related sizes. Don't update size until alloc
8046 done. Redo calculations to avoid overflow.
8047 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8049 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

8067 Check for size calculation overflow.
8068 (cache_face): Treat size calculation overflows as if they were
8069 memory exhaustion (the usual treatment), rather than aborting.
8071 * xfns.c (x_encode_text, x_set_name_internal)
8072 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8073 sizes, since they can exceed INT_MAX in size. Check for size

8077 (xg_select): Check for size calculation overflow.
8078 Don't update size until alloc done.
8080 * xrdb.c (get_environ_db): Don't assume path length fits in int,

8083 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8084 (X_LONG_MIN): New macros.
8085 Use them to make the following changes clearer.
8086 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8087 This change doesn't affect the value now, but it may help remind
8088 future maintainers not to raise the value too much later.
8089 (SELECTION_QUANTUM): Remove, replacing with ...
8090 (selection_quantum): ... new function, which avoids overflow.
8092 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8093 assumption that selection length fits in 'int'.
8094 (x_reply_selection_request, x_handle_selection_request)
8095 (x_get_window_property, receive_incremental_selection)
8096 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8097 (lisp_data_to_selection_data, clean_local_selection_data):

8101 Redo calculations to avoid overflow.
8102 (x_reply_selection_request): When sending hint, ceiling it at
8103 X_LONG_MAX rather than relying on wraparound overflow to send

8106 (lisp_data_to_selection_data, x_property_data_to_lisp):
8107 Check for size-calculation overflow.

8110 Don't store size until memory allocation succeeds.
8111 (x_get_window_property): Plug memory leak on memory exhaustion.
8112 Don't double-block input; malloc is safe here. Don't assume 2**34
8113 - 4 fits in unsigned long. Add an xassert to check
8114 XGetWindowProperty overflow. Be more careful about overflow
8115 calculations, and distinguish size from memory overflow better.
8116 (receive_incremental_selection): When tracing, don't assume
8117 unsigned int is less than INT_MAX.
8118 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8119 harmful) conversions of unsigned short to int.
8120 (lisp_data_to_selection_data): Don't assume that integers
8121 in the range -65535 through -1 fit in an X unsigned short.
8122 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8123 result parameters unless successful. Rely on cons_to_unsigned
8124 to report problems with elements; the old code wasn't right anyway.
8125 (x_check_property_data): Check for int overflow; we cannot use
8126 a wider type due to X limits.
8127 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8159 * lisp.h (hash_lookup, hash_put):
8160 * minibuf.c (Ftest_completion):
8161 Use ptrdiff_t for hash table indexes, not int (which is too
8162 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8163 32-bit --with-wide-int hosts).
8165 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8166 Add a FIXME comment about memory leaks.

8171 * character.h (CHAR_WIDTH):
8172 * indent.c (MULTIBYTE_BYTES_WIDTH):
8173 Use sanitize_char_width to avoid undefined and/or bad behavior
8174 with outlandish widths.
8175 * character.h (sanitize_tab_width): Rename from sanitize_width,
8176 now that we have two such functions. All uses changed.
8177 (sanitize_char_width): New inline function.
8179 Don't assume that tab-width fits in int.
8180 * character.h (sanitize_width): New inline function.
8181 (SANE_TAB_WIDTH): New macro.

8185 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
8187 * fileio.c: Integer overflow issues with file modes.
8188 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
8190 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
8191 Remove unreachable code.
8192 (read_hex, load_charset_map_from_file): Check for integer overflow.
8194 * xterm.c: Don't go over XClientMessageEvent limit.
8195 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8196 (x_send_scroll_bar_event): Likewise. Check that the size does not
8197 exceed limits imposed by XClientMessageEvent, as well as the usual
8198 ptrdiff_t and size_t limits.
8200 * keyboard.c: Overflow, signedness and related fixes.
8201 (make_lispy_movement): Use same integer type in forward decl
8202 that is used in the definition.
8203 (read_key_sequence, keyremap_step):
8204 Change bufsize argument back to int, undoing my 2011-03-30 change.
8205 We prefer signed types, and int is wide enough here.
8206 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8207 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8208 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8209 length, not size_t. Use ptrdiff_t for index, not int.
8210 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8211 possibility of integer overflow.
8213 Overflow, signedness and related fixes for images.
8215 * dispextern.h (struct it.stack[0].u.image.image_id)

8222 * nsmenu.m (update_frame_tool_bar):
8223 * xdisp.c (calc_pixel_width_or_height):
8224 * xfns.c (image_cache_refcount):
8225 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8226 on typical 64-bit hosts.
8228 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8229 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8232 when the callers expect that.
8233 (image_ascent): Redo ascent calculation to avoid int overflow.
8234 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8235 (lookup_image): Remove unnecessary tests.
8236 (xbm_image_p): Locals are now of int, not EMACS_INT,
8237 since parse_image_check makes sure they fit into int.
8238 (png_load, gif_load, svg_load_image):
8239 Prefer int to unsigned where either will do.
8240 (tiff_handler): New function, combining the cores of the
8241 old tiff_error_handler and tiff_warning_handler.
8242 This function is rewritten to use vsnprintf and thereby avoid
8243 stack buffer overflows. It uses only the features of vsnprintf
8244 that are common to both POSIX and native Microsoft.
8245 (tiff_error_handler, tiff_warning_handler): Use it.
8246 (tiff_load, gif_load, imagemagick_load_image):
8247 Don't assume :index value fits in 'int'.
8248 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8249 (imagemagick_load_image): Check that crop parameters fit into
8250 the integer types that MagickCropImage accepts. Don't assume
8251 Vimagemagick_render_type has a nonnegative value. Don't assume
8252 size_t fits in 'long'.
8253 (gs_load): Use printmax_t to print the widest integers possible.
8254 Check for integer overflow when computing image height and width.
8256 2011-08-26 Eli Zaretskii <eliz@gnu.org>

8266 handle_single_display_spec, not just 1 or zero.
8267 (handle_single_display_spec): If the display spec is of the form
8268 `(space ...)', and specifies display in the text area, return 2
8270 (try_cursor_movement): Check for the need to scroll more
8271 accurately, and prefer exact match for point under bidi.
8272 Don't advance `row' beyond the last row of the window.
8274 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8275 into disp_prop; all users changed.
8277 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8278 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8279 for the text covered by the display property.
8281 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8283 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8289 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8290 buffers, return left-to-right.
8291 (set_cursor_from_row): Consider candidate row a win if its glyph
8292 represents a newline and point is on that newline. Fixes cursor
8293 positioning on the newline at EOL of R2L text within L2R
8294 paragraph, and vice versa.
8295 (try_cursor_movement): Check continued rows, in addition to
8296 continuation rows. Fixes unwarranted scroll when point enters a
8297 continued line of R2L text within an L2R paragraph, or vice versa.
8298 (cursor_row_p): Consider the case of point being equal to
8299 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8300 from the end of a short line to the beginning of a continued line
8301 of R2L text within L2R paragraph.
8302 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8303 composed characters.
8305 * bidi.c (bidi_check_type): Use xassert.
8306 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8309 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8311 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
8314 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8316 * nsfont.m (ns_otf_to_script): Fix typo.
8318 2011-08-22 Kenichi Handa <handa@m17n.org>
8320 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8321 extra slot even if the purpose is char-code-property-table.
8323 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8325 * xdisp.c (redisplay_window): When computing centering_position,
8326 account for the height of the header line. (Bug#8874)
8328 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8329 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8330 candidate is selected by the mouse, and that candidate has a
8331 composed character under the mouse.
8333 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8334 coordinates reported by pos-visible-in-window-p for a composed
8335 character in column zero.
8337 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8339 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8341 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8343 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8344 consider it a hit if to_charpos is anywhere in the range of the
8345 composed buffer positions.
8347 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8349 * image.c (gif_load): Don't assume that each subimage has the same
8350 dimensions as the base image. Handle disposal method that is
8351 "undefined" by the gif spec (Bug#9335).
8353 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8355 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8356 (Fcondition_case): Document `debug' symbol in error handler.
8358 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8360 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8361 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8362 from an Org mode buffer to a Speedbar frame.
8364 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8365 a composition, take its buffer position from IT->cmp_it.charpos.
8366 Fixes cursor positioning at the beginning of a line that begins
8367 with a composed character.
8369 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8371 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8372 character bidirectional type, use STRONG_L instead. Fixes crashes
8373 in a buffer produced by `describe-categories'.
8375 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8376 members before the level stack, so they would be saved and
8377 restored when copying iterator state. Fixes incorrect reordering
8378 around TABs covered by display properties.
8380 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8382 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8454 ppos_it. Fixes vertical cursor motion when line beginning is
8455 covered by an image. (Bug#9296)
8457 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8459 * nsterm.h (ns_run_ascript): Declare.

8463 (ns_run_ascript): New function.
8464 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8465 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8466 the event loop. Get status from as_status (Bug#7276).
8468 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8469 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8470 the event loop (Bug#7276).

8496 (Fnetwork_interface_list): Allocate in increments of bytes instead
8497 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8498 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8500 (struct ifflag_def): notrailers is smart on OSX.
8501 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8502 Get hardware address with getifaddrs if available.
8504 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8506 * xdisp.c (iterate_out_of_display_property): xassert that
8507 IT->position is set to within IT->object's boundaries. Break from
8508 the loop as soon as EOB is reached; avoids infloops in redisplay
8509 when IT->position is set up wrongly due to some bug.
8510 Set IT->current to match the bidi iterator unconditionally.
8511 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8512 entry. Force push_it to save on the stack the current
8513 buffer/string position, to be restored by pop_it. Fix flags in
8514 the iterator structure wrt the object coming from a display
8515 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8516 properties. (Bug#9284)
8518 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8520 * fontset.c (fontset_get_font_group): Add proper type checks.

8535 properties and overlays.
8537 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8539 * editfns.c (Fset_time_zone_rule): Document relationship with the

8548 restore_point_unwind (Bug#5984).
8550 2011-08-07 Juri Linkov <juri@jurta.org>
8552 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8553 to show the arg `TIME' instead of `TIMEVAL'.

8559 longlines-mode. (Bug#9254)
8560 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8561 word-wrap under bidirectional display. (Bug#9224)
8563 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8564 is non-zero, even if the data buffer is NULL. Fixes a crash in
8565 vertical-motion with longlines-mode. (Bug#9254)
8567 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8569 * bidi.c <bidi_cache_total_alloc>: Now static.

8572 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8575 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8576 amount allocated this far in `bidi_cache_total_alloc'.
8577 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8578 non-zero, only free the data buffer without restoring the cache
8579 contents. All callers changed.
8581 * dispextern.h (bidi_unshelve_cache): Update prototype.
8583 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8584 (move_it_in_display_line, move_it_to)
8585 (move_it_vertically_backward, move_it_by_lines): Replace the call
8586 to xfree to an equivalent call to bidi_unshelve_cache.
8587 (move_it_in_display_line_to): Fix logic of returning
8588 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8590 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8592 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

8666 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8668 (reseat_at_next_visible_line_start): Use the bidi iterator state
8669 returned by forward_to_next_line_start to restore the state of
8670 it->bidi_it after backing up to previous newline. (Bug#9212)
8672 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8674 * regex.c (re_comp): Protoize.
8675 (re_exec): Fix return type.
8676 (regexec): Fix type of `ret'. (Bug#9203)
8678 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8680 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8681 This is needed if max-image-size is a floating-point number.
8683 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8685 * print.c (print_object): Print empty symbol as ##.
8687 * lread.c (read1): Read ## as empty symbol.
8689 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8691 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8692 setting frame foreground color (Bug#9175).
8693 (x_set_background_color): Likewise.
8695 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8696 contents (Bug#9176).
8697 (EmacsTooltip -init): Remove bezels and add shadows to
8700 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8701 or scroll bar (Bug#8470).
8703 * nsfont.m (nsfont_open): Remove assignment to voffset and
8704 unnecessary vars hshink, expand, hd, full_height, min_height.
8705 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8707 * nsterm.h (nsfont_info): Remove voffset field.
8709 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8711 Implement strike-through and overline on NextStep (Bug#8863).
8713 * nsfont.m (nsfont_open): Use underline position provided by font,
8714 instead of hard-coded value of 2.
8715 (nsfont_draw): Call ns_draw_text_decoration instead.
8717 * nsterm.h: Add declaration for ns_draw_text_decoration.
8719 * nsterm.m (ns_draw_text_decoration): New function for drawing
8720 underline, overline, and strike-through.
8721 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8722 ns_draw_text_decoration. Change treatment of cursor drawing to
8723 accommodate underlining, etc.
8725 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8727 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8730 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8732 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8733 Without this fix, if a signal arrives just after memory fills up,
8734 'malloc' might be invoked reentrantly.
8736 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8737 In other words, assume that every image size is allowed, on non-X
8738 hosts. This assumption is probably wrong, but it lets Emacs compile.
8740 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8742 * regex.c (re_iswctype): Convert return values to boolean.
8744 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8746 * xdisp.c (compute_display_string_pos): Don't use cached display
8747 string position if the buffer had its restriction changed.
8750 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8752 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8754 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8756 Integer signedness and overflow and related fixes. (Bug#9079)
8758 * bidi.c: Integer size and overflow fixes.
8759 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8760 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8761 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8762 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8763 (bidi_find_other_level_edge):
8764 Use ptrdiff_t instead of EMACS_INT where either will do.
8765 This works better on 32-bit hosts configured --with-wide-int.
8766 (bidi_cache_ensure_space): Check for size-calculation overflow.
8767 Use % rather than repeated addition, for better worst-case speed.
8768 Don't set bidi_cache_size until after xrealloc returns, because it
8770 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8771 (bidi_cache_ensure_space): Also check that the bidi cache size
8772 does not exceed that of the largest Lisp string or buffer. See Eli
8773 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8775 * alloc.c (__malloc_size_t): Remove.
8776 All uses replaced by size_t. See Andreas Schwab's note
8777 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8779 * image.c: Improve checking for integer overflow.
8780 (check_image_size): Assume that f is nonnull, since
8781 it is always nonnull in practice. This is one less thing to
8782 worry about when checking for integer overflow later.
8783 (x_check_image_size): New function, which checks for integer
8784 overflow issues inside X.
8785 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8786 This removes the need for a memory_full check.
8787 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8788 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8789 (xbm_read_bitmap_data): Change locals back to 'int', since
8790 their values must fit in 'int'.
8791 (xpm_load_image, png_load, tiff_load):
8792 Invoke x_create_x_image_and_pixmap earlier,
8793 to avoid much needless work if the image is too large.
8794 (tiff_load): Treat overly large images as if
8795 x_create_x_image_and_pixmap failed, not as malloc failures.
8796 (gs_load): Use x_check_image_size.
8798 * gtkutil.c: Omit integer casts.
8799 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8800 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8802 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8804 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8805 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8806 would wrongly return t on a 64-bit host.
8808 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8809 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8810 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8811 and therefore cause GCC to emit a bogus diagnostic in some cases.
8813 * image.c: Integer signedness and overflow and related fixes.
8814 This is not an exhaustive set of fixes, but it's time to
8815 record what I've got.
8816 (lookup_pixel_color, check_image_size): Remove redundant decls.
8817 (check_image_size): Don't assume that arbitrary EMACS_INT values
8818 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8819 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8820 (tiff_load, imagemagick_load_image):
8821 Check for overflow in size calculations.
8822 (x_create_x_image_and_pixmap): Remove unnecessary test for
8823 xmalloc returning NULL; that can't happen.
8824 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8825 (xpm_color_bucket): Use better integer hashing function.
8826 (xpm_cache_color): Don't possibly over-allocate memory.
8827 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8828 (gif_memory_source):
8829 Use ptrdiff_t, not int or size_t, to record sizes.
8830 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8831 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8832 either works, as we prefer signed integers.
8833 (tiff_read_from_memory, tiff_write_from_memory):
8834 Return tsize_t, not size_t, since that's what the TIFF API wants.
8835 (tiff_read_from_memory): Don't fail simply because the read would
8836 go past EOF; instead, return a short read.
8837 (tiff_load): Omit no-longer-needed casts.
8838 (Fimagemagick_types): Don't assume size fits into 'int'.
8840 Improve hashing quality when configured --with-wide-int.
8841 * fns.c (hash_string): New function, taken from sxhash_string.
8842 Do not discard information about ASCII character case; this
8843 discarding is no longer needed.
8844 (sxhash-string): Use it. Change sig to match it. Caller changed.
8845 * lisp.h: Declare it.
8846 * lread.c (hash_string): Remove, since we now use fns.c's version.
8847 The fns.c version returns a wider integer if --with-wide-int is
8848 specified, so this should help the quality of the hashing a bit.
8850 * emacs.c: Integer overflow minor fix.
8851 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8852 Define only if GNU_LINUX.
8853 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8855 * dispnew.c: Integer signedness and overflow fixes.
8856 Remove unnecessary forward decls, that were a maintenance hassle.
8857 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8859 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8860 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8861 (prepare_desired_row, line_draw_cost):
8862 Use int, not unsigned, where either works.
8863 (save_current_matrix, restore_current_matrix):
8864 Use ptrdiff_t, not size_t, where either works.
8865 (init_display): Check for overflow more accurately, and without
8866 relying on undefined behavior.
8868 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8869 Remove, replacing with the new symbols in lisp.h. All uses changed.
8870 * fileio.c (make_temp_name):
8871 * filelock.c (lock_file_1, lock_file):
8872 * xdisp.c (message_dolog):
8873 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8874 Use pMd etc. instead.
8875 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8876 replacing the pWIDE etc. symbols removed from editfns.c.
8878 * keyboard.h (num_input_events): Now uintmax_t.
8879 This is (very slightly) less likely to mess up due to wraparound.
8882 * buffer.c: Integer signedness fixes.
8883 (alloc_buffer_text, enlarge_buffer_text):
8884 Use ptrdiff_t rather than size_t when either will do, as we prefer
8887 * alloc.c: Integer signedness and overflow fixes.
8888 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8889 (__malloc_size_t): Default to size_t, not to int.
8890 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8891 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8892 Prefer ptrdiff_t to size_t when either would do, as we prefer
8894 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8895 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8896 Now const. Initialize with values that are in range even if char
8898 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8899 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8900 These functions do the right thing with sizes > 2**32.
8901 (check_depth): Now ptrdiff_t, not int.
8902 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8903 Adjust to new way of storing sizes. Check for size overflow bugs
8905 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8906 slightly wrong anyway, as it missed one instance of
8907 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8908 (refill_memory_reserve): Omit needless cast to size_t.
8909 (mark_object_loop_halt): Mark as externally visible.
8911 * xselect.c: Integer signedness and overflow fixes.
8912 (Fx_register_dnd_atom, x_handle_dnd_message):
8913 Use ptrdiff_t, not size_t, since we prefer signed.
8914 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8915 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8916 x_dnd_atoms_size and x_dnd_atoms_length.
8918 * doprnt.c: Prefer signed to unsigned when either works.
8920 * doprnt.c (doprnt):
8922 * xdisp.c (vmessage):
8923 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8924 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8925 prefer signed arithmetic to avoid comparison confusion.
8926 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8927 but is a bit tricky.
8929 Assume freestanding C89 headers, string.h, stdlib.h.
8930 * data.c, doprnt.c, floatfns.c, print.c:
8931 Include float.h unconditionally.
8932 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8933 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8934 * regex.c: Likewise for stddef.h, string.h.
8935 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8936 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8937 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8938 (STDC_HEADERS): Remove obsolete defines.
8939 * sysdep.c: Include limits.h unconditionally.
8941 Assume support for memcmp, memcpy, memmove, memset.
8942 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8943 * regex.c (memcmp, memcpy):
8944 Remove; we assume C89 now.
8946 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8947 (__malloc_safe_bcopy): Remove; no longer needed.
8949 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8950 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8951 well either way, and we prefer signed to unsigned.
8953 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8955 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8956 closes the connection while we're reading (bug#9182).
8958 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8960 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8961 are specified (Bug#9168).
8963 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8965 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8966 Found by GCC static checking and --with-wide-int on a 32-bit host.
8968 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8970 * xdisp.c (compute_display_string_pos): Fix logic of caching
8971 previous display string position. Initialize cached_prev_pos to
8972 -1. Fixes slow-down at the beginning of a buffer.
8974 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8976 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8977 for attrs[LFACE_FONTSET_INDEX].
8979 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8981 * xml.c (parse_region): Remove unused local
8982 that was recently introduced.
8984 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8986 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8987 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8989 * xdisp.c (move_it_in_display_line_to): Record the best matching
8990 position for TO_CHARPOS while scanning the line, and restore it on
8991 exit if none of the characters scanned was an exact match.
8992 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8993 when exact match is impossible due to invisible text, and the
8994 lines are truncated.
8996 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8998 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9001 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9003 Fix a significant slow-down of cursor motion with C-n, C-p,
9004 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9005 auto-repeat under bidi redisplay in fontified buffers.
9006 * xdisp.c (compute_stop_pos_backwards): New function.
9007 (next_element_from_buffer): Call compute_stop_pos_backwards to
9008 find a suitable prev_stop when we find ourselves before
9010 (reseat): Don't look for prev_stop, as that could mean a very long
9012 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9013 <cached_disp_overlay_modiff>: Cache for last found display string
9015 (compute_display_string_pos): Return the cached position if asked
9016 about the same buffer in the same area of character positions, and
9017 the buffer wasn't changed since the time the display string
9018 position was cached.
9020 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9022 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9023 is an integer, which is important for empty lines. (Bug#9149)
9025 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9027 * frame.c (Fmodify_frame_parameters): In tty case, update the
9028 default face if necessary (Bug#4238).
9030 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9032 * editfns.c (Fstring_to_char): No need to explain what a character
9033 is in the docstring (Bug#6576).
9035 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9037 * xml.c (parse_region): Make sure we always return a tree.
9039 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9041 * xml.c (parse_region): If a document contains only comments,
9044 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9046 * xml.c (make_dom): Return comments, too.
9048 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9051 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9052 and the surrounding thread.
9053 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9054 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9055 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9057 * s/openbsd.h (BROKEN_SIGIO): Define.
9058 * unexelf.c (unexec) [__OpenBSD__]:
9059 Don't update the .mdebug section of the Alpha COFF symbol table.
9061 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9063 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9066 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9068 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9069 This fixes some race conditions on the permissions of any newly
9072 * alloc.c (valid_pointer_p): Use pipe, not open.
9073 This fixes some permissions issues when debugging.
9075 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9076 If fchown fails to set both uid and gid, try to set just gid,
9077 as that is sometimes allowed. Adjust the file's mode to eliminate
9078 setuid or setgid bits that are inappropriate if fchown fails.
9080 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9082 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9083 to compare Lisp_Objects.
9084 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9085 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9086 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9088 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9090 * lread.c (read_integer): Unread even EOF character.
9091 (read1): Likewise. Properly record start position of symbol.
9093 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9094 symbol character follows.
9096 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9098 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9099 This works around a problem with the previous change to Fcopy_file.
9100 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9101 and without this change, GCC might complain about discarding
9102 fchown's return value.
9104 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9106 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9108 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9110 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9112 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9114 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9115 it's used from the C level.
9117 * process.c: Use the same condition for POLL_FOR_INPUT in both
9118 keyboard.c and process.c (bug#1858).
9120 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9122 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9123 (Fgnutls_boot): Use it.
9125 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9127 * doc.c (Fsubstitute_command_keys): Revert last change.

9200 the iterator is before prev_stop.
9201 (init_iterator): Initialize bidi_p from the default value of

9719 Random fixes. E.g., (random) never returned negative values.
9720 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9721 subseconds part to the entropy, as that's a bit more random.
9722 Prefer signed to unsigned, since the signedness doesn't matter and
9723 in general we prefer signed. When given a limit, use a
9724 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9725 latter isn't right if USE_2_TAGS_FOR_INTS.
9726 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9727 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9740 This is more efficient than Ffile_directory_p and avoids a minor race.
9742 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9744 * buffer.c (Foverlay_put): Say what the return value is
9747 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9750 (barf_or_query_if_file_exists): Make the "File is a directory"
9751 error be more correct.
9753 * fns.c (Frequire): Remove the mention of the .gz files, since
9754 that's installation-specific, but keep the mention of
9755 `get-load-suffixes'.
9757 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9759 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9770 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9872 * eval.c (struct backtrace): Simplify and port the data structure.
9873 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9874 signed bit field, as this assumption is not portable and it makes
9875 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9876 "char debug_on_exit : 1" as this is not portable either; instead,
9877 use the portable "unsigned int debug_on_exit : 1". Remove unused
9878 member evalargs. Remove obsolete comments about cc bombing out.

10042 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10044 Integer and buffer overflow fixes (Bug#8873).
10046 * print.c (printchar, strout): Check for string overflow.
10047 (PRINTPREPARE, printchar, strout):
10048 Don't set size unless allocation succeeds.
10050 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10051 for sizes. Check for string overflow more accurately.
10052 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10054 * macros.c: Integer and buffer overflow fixes.
10055 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10056 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10057 Use ptrdiff_t, not int, for sizes.
10058 Don't increment bufsize until after realloc succeeds.
10059 Check for size-calculation overflow.
10060 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10062 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10064 * lread.c: Integer overflow fixes.
10065 (read_integer): Radix is now EMACS_INT, not int,
10066 to improve quality of diagnostics for out-of-range radices.
10067 Calculate buffer size correctly for out-of-range radices.
10068 (read1): Check for integer overflow in radices, and in
10069 read-circle numbers.
10070 (read_escape): Avoid int overflow.
10071 (Fload, openp, read_buffer_size, read1)
10072 (substitute_object_recurse, read_vector, read_list, map_obarray):
10073 Use ptrdiff_t, not int, for sizes.
10074 (read1): Use EMACS_INT, not int, for sizes.
10075 Check for size overflow.
10077 * image.c (cache_image): Check for size arithmetic overflow.
10079 * lread.c: Integer overflow issues.
10080 (saved_doc_string_size, saved_doc_string_length)
10081 (prev_saved_doc_string_size, prev_saved_doc_string_length):
10082 Now ptrdiff_t, not int.
10083 (read1): Don't assume doc string length fits in int. Check for
10084 out-of-range doc string lengths.

10086 (read_escape): Check for hex character overflow.
10088 2011-06-22 Leo Liu <sdl.web@gmail.com>
10090 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10091 Move to minibuffer.el.
10093 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10095 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10096 The following patches are for when GLYPH_DEBUG && !XASSERT.
10097 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10098 * dispnew.c (flush_stdout):
10099 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10100 Mark as externally visible.
10101 * dispnew.c (check_window_matrix_pointers): Now static.
10102 * dispnew.c (window_to_frame_vpos):
10103 * xfns.c (unwind_create_frame):
10104 * xterm.c (x_check_font): Remove unused local.
10105 * scroll.c (CHECK_BOUNDS):
10106 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10107 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10108 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10109 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10110 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10112 (debug_method_add): Use va_list and vsprintf rather than relying
10113 on undefined behavior with wrong number of arguments.
10114 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10115 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10116 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10117 since we're not interested in debugging glyphs with old libraries.
10118 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10119 GCC 4.6.0's static checking.
10121 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10123 Integer overflow and signedness fixes (Bug#8873).

10132 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10133 (x_create_bitmap_from_xpm_data):
10134 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10135 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10137 * xfaces.c (load_pixmap):
10138 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10139 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10140 (.bitmaps_last, struct x_output.icon_bitmap):
10141 Use ptrdiff_t, not int, for bitmap indexes.
10142 (x_allocate_bitmap_record): Check for size overflow.
10143 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10145 Use ptrdiff_t, not int, for overlay counts.
10146 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10147 * editfns.c (overlays_around, get_pos_property):
10148 * textprop.c (get_char_property_and_overlay):
10149 * xdisp.c (next_overlay_change, note_mouse_highlight):
10150 * xfaces.c (face_at_buffer_position):
10151 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10152 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10153 (Fnext_overlay_change, Fprevious_overlay_change)
10154 (mouse_face_overlay_overlaps, Foverlays_in):
10155 Use ptrdiff_t, not int, for sizes.
10156 (overlays_at, overlays_in): Check for size-calculation overflow.
10158 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10160 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10161 (x_session_initialize): Do not assume string length fits in int.
10163 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10164 This is unlikely, but can occur if DPI is outlandish.
10166 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10167 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10169 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10170 * xrdb.c (magic_file_p, search_magic_path):
10171 Omit last arg SUFFIX; it was always 0. All callers changed.
10172 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10174 * xfont.c (xfont_match): Avoid need for strlen.
10176 * xfns.c: Don't assume strlen fits in int.
10177 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10179 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10180 not unsigned long, as we prefer signed integers. All callers changed.
10181 Detect integer overflow in repeat count.
10182 (message_dolog): Don't assume print length fits in 39 bytes.
10183 (display_mode_element): Don't assume strlen fits in int.
10185 * termcap.c: Don't assume sizes fit in int and never overflow.
10186 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10187 (gobble_line): Check for size-calculation overflow.
10189 * minibuf.c (Fread_buffer):
10190 * lread.c (intern, intern_c_string):
10191 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10192 Don't assume string length fits in int.
10194 * keyboard.c (parse_tool_bar_item):
10195 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10197 * font.c: Don't assume string length fits in int.
10198 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10199 Use ptrdiff_t, not int.
10200 (font_intern_prop): Don't assume string length fits in int.
10201 Don't assume integer property fits in fixnum.
10202 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10204 * filelock.c: Fix some buffer overrun and integer overflow issues.
10205 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10206 Reformulate so as not to need the command string.
10207 Invoke gzip -cd rather than gunzip, as it's more portable.
10208 (lock_info_type, lock_file_1, lock_file):
10209 Don't assume pid_t and time_t fit in unsigned long.
10210 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10211 (current_lock_owner): Prefer signed type for sizes.
10212 Use memcpy, not strncpy, where memcpy is what is really wanted.
10213 Don't assume (via atoi) that time_t and pid_t fit in int.
10214 Check for time_t and/or pid_t out of range, e.g., via a network share.
10215 Don't alloca where an auto var works fine.
10217 * fileio.c: Fix some integer overflow issues.
10218 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10219 Don't assume string length fits in int.
10220 (directory_file_name): Don't assume string length fits in long.
10221 (make_temp_name): Don't assume pid fits in int, or that its print
10222 length is less than 20.
10224 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10226 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10228 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10230 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10231 We prefer signed integers, even for size calculations.
10233 * emacs.c: Don't assume string length fits in 'int'.
10234 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10235 (main): Don't invoke strlen when not needed.
10237 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10238 (XD_DEBUG_MESSAGE): Don't waste a byte.
10240 * callproc.c (getenv_internal_1, getenv_internal)
10241 (Fgetenv_internal):
10242 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10244 * lread.c (invalid_syntax): Omit length argument.
10245 All uses changed. This doesn't fix a bug, but it simplifies the
10246 code away from its former Hollerith-constant appearance, and it's
10247 one less 'int' to worry about when looking at integer-overflow issues.
10248 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10250 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10251 This didn't break anything, but it didn't help either.
10252 It's confusing to put a bogus integer in a place where the actual
10253 value does not matter.
10254 (LIST_END_P): Remove unused macro and its bogus comment.
10255 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10257 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10258 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10260 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10261 We prefer signed types, and the value cannot exceed the EMACS_INT
10262 range anyway (because otherwise the length would not be representable).
10263 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10264 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10265 This avoids a GCC warning when WIDE_EMACS_INT.
10267 * indent.c (sane_tab_width): New function.
10268 (current_column, scan_for_column, Findent_to, position_indentation)
10269 (compute_motion): Use it. This is just for clarity.
10270 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10272 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10274 * lisp.h (lint_assume): New macro.
10275 * composite.c (composition_gstring_put_cache):
10276 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10278 * editfns.c, insdel.c:
10279 Omit unnecessary forward decls, to simplify future changes.
10281 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10283 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10285 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10286 Use much-faster test for byte-length change.
10287 Don't assume string byte-length fits in 'int'.
10288 Check that character arg fits in 'int'.
10289 (mapcar1): Declare byte as byte, for clarity.
10291 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10293 * fns.c (concat): Catch string overflow earlier.
10294 Do not rely on integer wraparound.
10296 * dispextern.h (struct it.overlay_strings_charpos)
10297 (struct it.selective): Now EMACS_INT, not int.
10298 * xdisp.c (forward_to_next_line_start)
10299 (back_to_previous_visible_line_start)
10300 (reseat_at_next_visible_line_start, next_element_from_buffer):
10301 Don't arbitrarily truncate the value of 'selective' to int.
10303 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10305 * composite.c: Don't truncate sizes to 'int'.
10306 (composition_gstring_p, composition_reseat_it)
10307 (composition_adjust_point): Use EMACS_INT, not int.
10308 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10309 not EMACS_UINT, for indexes.
10311 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10313 * buffer.c: Include <verify.h>.
10314 (struct sortvec.priority, struct sortstr.priority):
10315 Now EMACS_INT, not int.
10316 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10317 (struct sortstr.size, record_overlay_string)
10318 (struct sortstrlist.size, struct sortlist.used):
10319 Don't truncate size to int.
10320 (record_overlay_string): Check for size-calculation overflow.
10321 (init_buffer_once): Check at compile-time, not run-time.
10323 2011-06-22 Jim Meyering <meyering@redhat.com>
10325 Don't leak an XBM-image-sized buffer
10326 * image.c (xbm_load): Free the image buffer after using it.
10328 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10331 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10332 that Sun C diagnosed.
10333 * fns.c (secure_hash): Fix pointer signedness issue.
10334 * intervals.c (static_offset_intervals): New function.
10335 (offset_intervals): Use it.
10337 2011-06-21 Leo Liu <sdl.web@gmail.com>
10340 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10343 * fns.c (secure_hash): Rename from crypto_hash_function and change
10344 the first arg to accept symbols.
10345 (Fsecure_hash): New primitive.
10346 (syms_of_fns): New symbols.
10348 2011-06-20 Deniz Dogan <deniz@dogan.se>
10350 * process.c (Fset_process_buffer): Clarify return value in
10353 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10355 * dispnew.c (add_window_display_history): Use BVAR.
10357 * xdisp.c (debug_method_add): Use BVAR.
10358 (check_window_end, dump_glyph_matrix, dump_glyph)
10359 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10361 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10364 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10365 check till after the cache is created in init_frame_faces.
10367 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10369 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10371 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10373 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10374 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10375 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10377 Improve buffer-overflow checking (Bug#8873).
10378 * fileio.c (Finsert_file_contents):
10379 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10380 Remove the old (too-loose) buffer overflow checks.
10381 They weren't needed, since make_gap checks for buffer overflow.
10382 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10383 The old code merely checked for Emacs fixnum overflow, and relied
10384 on undefined (wraparound) behavior. The new code avoids undefined
10385 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10387 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10388 Tune. Don't use wider integers than needed. Don't use alloca.
10389 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10391 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10393 * insdel.c, lisp.h (buffer_overflow): New function.
10394 (insert_from_buffer_1, replace_range, replace_range_2):
10395 * insdel.c (make_gap_larger):
10396 * editfns.c (Finsert_char):
10397 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10399 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10401 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10403 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10405 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10406 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10408 * fileio.c: Don't assume EMACS_INT fits in off_t.
10409 (emacs_lseek): New static function.
10410 (Finsert_file_contents, Fwrite_region): Use it.
10411 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10413 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10415 * fns.c: Don't overflow int when computing a list length.
10416 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10417 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10418 truncation on 64-bit hosts. Check for QUIT every
10419 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10420 faster and is responsive enough.
10421 (Flength): Report an error instead of overflowing an integer.
10422 (Fsafe_length): Return a float if the value is not representable
10423 as a fixnum. This shouldn't happen except in contrived situations.
10424 (Fnthcdr, Fsort): Don't assume list length fits in int.
10425 (Fcopy_sequence): Don't assume vector length fits in int.
10427 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10428 (header_size, word_size): New constants.
10429 (allocate_vectorlike): Don't check size overflow here.
10430 (allocate_vector): Check it here instead, since this is the only
10431 caller of allocate_vectorlike that could cause overflow.
10432 Check that the new vector's length is representable as a fixnum.
10434 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10435 The previous code was bogus. For example, next_almost_prime (32)
10436 returned 39, which is undesirable as it is a multiple of 3; and
10437 next_almost_prime (24) returned 25, which is a multiple of 5 so
10438 why was the code bothering to check for multiples of 7?
10440 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10442 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10444 Variadic C functions now count arguments with ptrdiff_t.
10445 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10446 Back then I didn't know that the Emacs coding style prefers signed int.
10447 Also, in the meantime I found a few more instances where arguments
10448 were being counted with int, which may truncate counts on 64-bit
10449 machines, or EMACS_INT, which may be unnecessarily wide.
10450 * lisp.h (struct Lisp_Subr.function.aMANY)
10451 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10452 Arg counts are now ptrdiff_t, not size_t.
10453 All variadic functions and their callers changed accordingly.
10454 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10455 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10456 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10457 * callint.c (Fcall_interactively): Check arg count for overflow,
10458 to avoid potential buffer overrun. Use signed char, not 'int',
10459 for 'varies' array, so that we needn't bother to check its size
10460 calculation for overflow.
10461 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10462 * eval.c (apply_lambda):
10463 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10464 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10465 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10467 * callint.c (Fcall_interactively): Don't use index var as event count.
10469 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10470 * mem-limits.h (SIZE): Remove; no longer used.
10472 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10474 Remove unnecessary casts.
10475 * xterm.c (x_term_init):
10476 * xfns.c (x_set_border_pixel):
10477 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10478 These aren't needed now that we assume ANSI C.
10480 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10481 It's more likely to cause problems (due to unsigned overflow)
10484 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10486 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10488 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10490 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10492 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10494 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10496 GLYPH_CODE_FACE returns EMACS_INT, not int.
10497 * dispextern.h (merge_faces):
10498 * xfaces.c (merge_faces):
10499 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10500 Don't assume EMACS_INT fits in int.
10502 * character.h (CHAR_VALID_P): Remove unused parameter.
10503 * fontset.c, lisp.h, xdisp.c: All uses changed.
10505 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10507 * fns.c (concat): Minor tuning based on overflow analysis.
10508 This doesn't fix any bugs. Use int to hold character, instead
10509 of constantly refetching from Emacs object. Use XFASTINT, not
10510 XINT, for value known to be a character. Don't bother comparing
10511 a single byte to 0400, as it's always less.
10513 * floatfns.c (Fexpt):
10514 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10516 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10519 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10521 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10522 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10523 incorrectly succeed when S was a string, because 4294967386 was
10524 truncated before it was used.
10526 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10527 Otherwise, an out-of-range integer could cause undefined behavior
10530 * composite.c: Use int, not EMACS_INT, for characters.
10531 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10532 EMACS_INT, for values that are known to be in character range.
10533 This doesn't fix any bugs but is the usual style inside Emacs and
10534 may generate better code on 32-bit machines.
10536 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10537 This is for reasons similar to the recent CHAR_STRING fix.
10538 * charset.c (Fencode_char): Check that character arg is actually
10539 a character. Pass an int to ENCODE_CHAR.
10540 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10541 wider than 'int', as a compile-time check to prevent future regressions
10544 * character.c (char_string): Remove unnecessary casts.
10546 Make sure a 64-bit char is never passed to CHAR_STRING.
10547 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10548 by silently ignoring the top 32 bits, allowing some values
10549 that were far too large to be valid characters.
10550 * character.h: Include <verify.h>.
10551 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10552 arguments are no wider than unsigned, as a compile-time check
10553 to prevent future regressions in this area.
10555 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10556 (Fsubst_char_in_region):
10558 * xdisp.c (decode_mode_spec_coding):
10559 Adjust to CHAR_STRING's new requirement.
10560 * editfns.c (Finsert_char, Fsubst_char_in_region):
10561 * fns.c (concat): Check that character args are actually
10562 characters. Without this test, these functions did the wrong
10563 thing with wildly out-of-range values on 64-bit hosts.
10565 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10566 These casts should not be needed on 32-bit hosts, either.
10567 * keyboard.c (read_char):
10568 * lread.c (Fload): Remove casts to unsigned.
10570 * lisp.h (UNSIGNED_CMP): New macro.
10571 This fixes comparison bugs on 64-bit hosts.
10572 (ASCII_CHAR_P): Use it.
10573 * casefiddle.c (casify_object):
10574 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10575 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10576 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10577 * dispextern.h (FACE_FROM_ID):
10578 * keyboard.c (read_char): Use UNSIGNED_CMP.
10580 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10581 not to EMACS_INT, to avoid GCC warning.
10583 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10585 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10586 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10587 isn't needed on 32-bit machines.
10589 * buffer.c (Fgenerate_new_buffer_name):
10590 Use EMACS_INT for count, not int.
10591 (advance_to_char_boundary): Return EMACS_INT, not int.
10593 * data.c (Qcompiled_function): Now static.
10595 * window.c (window_body_lines): Now static.
10597 * image.c (gif_load): Rename local to avoid shadowing.
10599 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10600 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10601 * alloc.c (make_save_value): Integer argument is now of type
10602 ptrdiff_t, not int.
10603 (mark_object): Use ptrdiff_t, not int.
10604 * lisp.h (pD): New macro.
10605 * print.c (print_object): Use it.
10607 * alloc.c: Use EMACS_INT, not int, to count objects.
10608 (total_conses, total_markers, total_symbols, total_vector_size)
10609 (total_free_conses, total_free_markers, total_free_symbols)
10610 (total_free_floats, total_floats, total_free_intervals)
10611 (total_intervals, total_strings, total_free_strings):
10612 Now EMACS_INT, not int. All uses changed.
10613 (Fgarbage_collect): Compute overall total using a double, so that
10614 integer overflow is less likely to be a problem. Check for overflow
10615 when converting back to an integer.
10616 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10617 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10618 These were 'int' variables that could overflow on 64-bit hosts;
10619 they were never used, so remove them instead of repairing them.
10620 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10621 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10622 Previously, this ceilinged at INT_MAX, but that doesn't work on
10624 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10626 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10627 (allocate_vectorlike): Check for ptrdiff_t overflow.
10628 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10629 when a (possibly-narrower) signed value would do just as well.
10630 We prefer using signed arithmetic, to avoid comparison confusion.
10632 * alloc.c: Catch some string size overflows that we were missing.
10633 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10634 for convenience in STRING_BYTES_MAX.
10635 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10636 The definition here is exact; the one in lisp.h was approximate.
10637 (allocate_string_data): Check for string overflow. This catches
10638 some instances we weren't catching before. Also, it catches
10639 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10640 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10641 and ptrdiff_t and EMACS_INT are both 64 bits.
10643 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10644 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10645 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10647 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10649 * alloc.c (Fmake_string): Check for out-of-range init.
10651 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10653 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10655 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10657 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10658 xg_get_default_scrollbar_width.
10660 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10661 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10662 (style_changed_cb): Call update_theme_scrollbar_width and call
10663 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10664 all frames (Bug#8505).
10665 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10666 Call gtk_window_set_resizable if HAVE_GTK3.

10668 and height if HAVE_GTK3 (Bug#8505).
10669 (scroll_bar_width_for_theme): New variable.
10670 (update_theme_scrollbar_width): New function.
10671 (xg_get_default_scrollbar_width): Move code to
10672 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10673 (xg_initialize): Call update_theme_scrollbar_width.
10675 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10677 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10679 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10681 * frame.c (make_frame): Call other_buffer_safely instead of
10684 * window.c (temp_output_buffer_show): Call display_buffer with
10685 second argument Vtemp_buffer_show_specifiers and reset latter
10686 immediately after the call.
10687 (Vtemp_buffer_show_specifiers): New variable.
10688 (auto_window_vscroll_p, next_screen_context_lines)
10689 (Vscroll_preserve_screen_position): Remove leading asterisks from

10735 (Fset_window_configuration): Rewrite to handle dead buffers and
10736 consequently deletable windows.
10737 (window_tree, Fwindow_tree): Remove. Supply functionality in

10872 Remove static from declaration of Qdelete_window, it's
10873 temporarily needed by Fbury_buffer.
10874 (replace_window): Don't assign orig_top_line and
10876 (Fdelete_window, delete_window): Remove. Window deletion is

10878 (window_loop): Remove DELETE_OTHER_WINDOWS case.
10879 Replace Fdelete_window calls with calls to Qdelete_window.
10880 (Fdelete_other_windows): Remove. Deleting other windows is

11222 instead of using explicit *_CHAR codes.
11223 (bidi_resolve_explicit, bidi_resolve_weak):

11240 (display_prop_intangible_p): Reimplement to call
11241 handle_display_spec instead of single_display_spec_intangible_p.

11253 value of a `display' property is a "replacing spec".
11254 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11255 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11285 * gnutls.c: Use Emacs's memory allocators.
11286 Without this change, the gnutls library would invoke malloc etc.
11287 directly, which causes problems on non-SYNC_INPUT hosts, and which
11288 runs afoul of improving memory_full behavior. (Bug#8761)
11289 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11290 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11291 xfree instead of the default malloc, realloc, free.
11292 (Fgnutls_boot): No need to check for memory allocation failure,
11293 since xmalloc does that for us.

11317 * alloc.c (allocate_vectorlike):
11318 Check for overflow in vector size calculations.
11319 * ccl.c (ccl_driver):
11320 Check for overflow when converting EMACS_INT to int.

11322 need to be updated by these changes.
11323 * fns.c (make_hash_table, maybe_resize_hash_table):
11324 Check for integer overflow with large hash tables.
11325 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11326 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11327 (SXHASH_REDUCE): New macro.
11328 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11329 Use it instead of discarding useful hash info with large hash values.
11330 (sxhash_float): New function.
11331 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11332 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11333 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11334 Rewrite to use FIXNUM_BITS, as this simplifies things.
11335 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11336 Adjust signatures to match updated version of code.
11337 (consing_since_gc): Now EMACS_INT, since a single hash table can
11338 use more than INT_MAX bytes.
11340 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11342 Make it possible to build with GCC-4.6+ -O2 -flto.
11344 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11346 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11348 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11349 Call minibuffer-inactive-mode.
11351 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11353 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11354 Update dependencies.
11356 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11358 * data.c (init_data): Remove code for UTS, this system is not
11361 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11363 Don't force ./temacs to start in terminal mode.
11365 * frame.c (make_initial_frame): Initialize faces in all cases, not
11366 only when CANNOT_DUMP is defined.
11367 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11369 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11371 * dispnew.c (add_window_display_history): Use const for the string
11372 pointer. Remove declaration, not needed.
11374 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11376 Use 'inline', not 'INLINE'.
11377 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11378 * alloc.c, fontset.c (INLINE): Remove.
11379 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11380 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11381 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11382 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11383 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11385 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11387 Make it possible to run ./temacs.
11389 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11390 syms_of_callproc does the same thing. Remove test for
11391 "initialized", do it in the caller.
11392 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11394 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11396 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11397 (read_minibuf): Use get_minibuffer.
11398 (syms_of_minibuf): Use DEFSYM.
11399 (Qmetadata): New var.
11400 * data.c (Qbuffer): Don't make it static.
11401 (syms_of_data): Use DEFSYM.
11403 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11405 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11406 (CCL_CODE_MIN): New macro.
11408 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11410 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11412 * eval.c (Qdebug): Now static.
11413 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11414 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11415 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11417 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11419 * image.c: Various fixes to ImageMagick code comments.
11420 (Fimagemagick_types): Doc fix.
11422 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11424 Minor fixes prompted by GCC 4.6.0 warnings.
11426 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11428 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11429 (x_clipboard_manager_save_all): Move extern decl to ...
11430 * xterm.h: ... here, so that it can be checked for consistency.
11432 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11434 * xselect.c (x_clipboard_manager_save_frame)
11435 (x_clipboard_manager_save_all): New functions.
11436 (Fx_clipboard_manager_save): Lisp function deleted.
11438 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11439 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11441 * xterm.h: Update prototype.
11443 2011-05-28 William Xu <william.xwl@gmail.com>
11445 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11446 exiting (Bug#8239).
11448 2011-05-28 Jim Meyering <meyering@redhat.com>
11450 Avoid a sign-extension bug in crypto_hash_function.
11451 * fns.c (to_uchar): Define.
11452 (crypto_hash_function): Use it to convert some newly-signed
11453 variables to unsigned, to avoid sign-extension bugs. For example,
11454 without this change, (md5 "truc") would evaluate to
11455 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11456 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11457 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11459 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11461 Integer overflow fixes.
11463 * dbusbind.c: Serial number integer overflow fixes.
11464 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11465 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11466 to hold a serial number that is too large for a fixnum.
11467 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11468 Check for serial numbers out of range. Decode any serial number
11469 that was so large that it became a float. (Bug#8722)
11471 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11472 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11473 Use XFASTINT rather than XUINT when numbers are nonnegative.
11474 (xd_append_arg, Fdbus_method_return_internal):
11475 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11476 arguments, check that Lisp number is nonnegative, rather than
11477 silently wrapping negative numbers around. (Bug#8722)
11478 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11481 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11483 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11485 ccl: Add integer overflow checks.
11486 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11487 (IN_INT_RANGE): New macros.
11488 (ccl_driver): Use them to check for integer overflow when
11489 decoding a CCL program. Many of the new checks are whether XINT (x)
11490 fits in int; it doesn't always, on 64-bit hosts. The new version
11491 doesn't catch all possible integer overflows, but it's an
11492 improvement. (Bug#8719)
11494 * alloc.c (make_event_array): Use XINT, not XUINT.
11495 There's no need for unsigned here.
11497 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11498 This follows up to the 2011-05-06 change that substituted uintptr_t
11499 for EMACS_INT. This case wasn't caught back then.
11501 Rework Fformat to avoid integer overflow issues.
11502 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11503 now (part of C89). Include <verify.h>.
11504 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11505 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11506 (Fformat): Avoid the prepass trying to compute sizes; it was only
11507 approximate and thus did not catch overflow reliably. Instead, walk
11508 through the format just once, formatting and computing sizes as we go,
11509 checking for integer overflow at every step, and allocating a larger
11510 buffer as needed. Keep track separately whether the format is
11511 multibyte. Keep only the most-recently calculated precision, rather
11512 than them all. Record whether each argument has been converted to
11513 string. Use EMACS_INT, not int, for byte and char and arg counts.
11514 Support field widths and precisions larger than INT_MAX. Avoid
11515 sprintf's undefined behavior with conversion specifications such as %#d
11516 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11517 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11518 formatting out-of-range floating point numbers with int
11519 formats. (Bug#8668)
11521 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11523 * data.c: Avoid integer truncation in expressions involving floats.
11524 * data.c: Include <intprops.h>.
11525 (arith_driver): When there's an integer overflow in an expression
11526 involving floating point, convert the integers to floating point
11527 so that the resulting value does not suffer from catastrophic
11528 integer truncation. For example, on a 64-bit host (* 4
11529 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11530 Do not rely on undefined behavior after integer overflow.
11532 merge count_size_as_multibyte, parse_str_to_multibyte
11533 * character.c, character.h (count_size_as_multibyte):
11534 Rename from parse_str_to_multibyte; all uses changed.
11535 Check for integer overflow.
11536 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11537 since it's now a duplicate of the other. This is more of
11538 a character than a buffer op, so better that it's in character.c.
11539 * fns.c, print.c: Adjust to above changes.
11541 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11543 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11545 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11547 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11548 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11549 (x_clipboard_manager_save): Now static.
11550 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11552 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11553 (crypto_hash_function): Now static.
11554 Fix pointer signedness problems. Avoid unnecessary initializations.
11556 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11558 * termhooks.h (Vselection_alist): Make it terminal-local.
11560 * terminal.c (create_terminal): Initialize it.
11562 * xselect.c: Support for clipboard managers.
11563 (Vselection_alist): Move to termhooks.h as terminal-local var.
11564 (LOCAL_SELECTION): New macro.
11565 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11566 (symbol_to_x_atom): Remove gratuitous arg.
11567 (x_handle_selection_request, lisp_data_to_selection_data)
11568 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11569 (x_own_selection, x_get_local_selection, x_convert_selection):
11570 New arg, specifying work frame. Use terminal-local Vselection_alist.
11571 (some_frame_on_display): Delete unused function.
11572 (Fx_own_selection_internal, Fx_get_selection_internal)
11573 (Fx_disown_selection_internal, Fx_selection_owner_p)
11574 (Fx_selection_exists_p): New optional frame arg.
11575 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11576 (x_handle_selection_clear): Don't treat other terminals with the
11577 same keyboard specially. Use the terminal-local Vselection_alist.
11578 (x_clear_frame_selections): Use Frun_hook_with_args.
11580 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11582 * xterm.h: Add support for those atoms.
11584 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11586 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11587 (converted_selections, conversion_fail_tag): New global variables.
11588 (x_selection_request_lisp_error): Free the above.
11589 (x_get_local_selection): Remove unnecessary code.
11590 (x_reply_selection_request): Args changed; handle arbitrary array
11591 of converted selections stored in converted_selections.
11592 Separate the XChangeProperty and SelectionNotify steps.
11593 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11594 (x_convert_selection): New function.
11595 (x_handle_selection_event): Simplify.
11596 (x_get_foreign_selection): Don't ignore incoming requests while
11597 waiting for an answer; this will fail when we implement
11598 SAVE_TARGETS, and seems unnecessary anyway.
11599 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11600 (Vx_sent_selection_functions): Doc fix.
11602 2011-05-26 Leo Liu <sdl.web@gmail.com>
11604 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11606 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11608 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11610 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11611 for fringe update if it has periodic bitmap.
11612 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11613 and fringe_bitmap_periodic_p.
11615 * fringe.c (get_fringe_bitmap_data): New function.
11616 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11617 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11618 row. Mark glyph row for fringe update if periodicity changed.
11620 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11621 for fringe update unless it has periodic bitmap.
11623 2011-05-25 Kenichi Handa <handa@m17n.org>
11625 * xdisp.c (get_next_display_element): Set correct it->face_id for
11626 a static composition.
11628 2011-05-24 Leo Liu <sdl.web@gmail.com>
11631 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11633 * fns.c (crypto_hash_function, Fsha1): New function.
11634 (Fmd5): Use crypto_hash_function.
11635 (syms_of_fns): Add Ssha1.
11637 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11639 * gnutls.c: Remove unused macros.
11640 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11641 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11642 Remove macros that are defined and never used.
11643 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11645 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11647 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11648 (Fx_get_selection_internal): Minor cleanup.
11649 (Fx_own_selection_internal): Rename arguments for consistency with
11652 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11654 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11656 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11658 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11660 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11662 * dispnew.c (scrolling_window): Don't exclude the case that the
11663 last enabled row in the desired matrix touches the bottom boundary.
11665 2011-05-21 Glenn Morris <rgm@gnu.org>
11667 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11668 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11669 and add some more files.
11671 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11673 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11674 report_file_error introduced by the change from 2011-05-07.
11676 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11678 * systime.h (Time): Define only if emacs is defined.
11679 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11680 where the include path doesn't have X11/X.h by default. See
11681 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11683 2011-05-20 Kenichi Handa <handa@m17n.org>
11685 * composite.c (find_automatic_composition): Fix previous change.
11687 2011-05-20 Glenn Morris <rgm@gnu.org>
11689 * lisp.mk: New file, split from Makefile.in.
11690 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11691 (shortlisp): Remove.
11692 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11694 2011-05-19 Glenn Morris <rgm@gnu.org>
11696 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11697 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11698 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11699 (lisp): Set the order to that of loadup.el.
11700 (shortlisp): Make it a copy of $lisp.
11701 (SOME_MACHINE_LISP): Remove.
11702 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11703 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11705 2011-05-18 Kenichi Handa <handa@m17n.org>
11707 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11708 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11709 (find_automatic_composition): Mostly rewrite for efficiency.
11711 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11713 * makefile.w32-in: Update dependencies.
11715 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11717 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11718 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11720 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11722 Fix some integer overflow issues, such as string length overflow.
11724 * insdel.c (count_size_as_multibyte): Check for string overflow.
11726 * character.c (lisp_string_width): Check for string overflow.
11727 Use EMACS_INT, not int, for string indexes and lengths; in
11728 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11729 the resulting string length overflows an EMACS_INT; instead,
11730 report a string overflow if no precision given. When checking for
11731 precision exhaustion, use a check that cannot possibly have
11732 integer overflow. (Bug#8675)
11733 * character.h (lisp_string_width): Adjust to new signature.
11735 * alloc.c (string_overflow): New function.
11736 (Fmake_string): Use it. This doesn't change behavior, but saves
11737 a few bytes and will simplify future changes.
11738 * character.c (string_escape_byte8): Likewise.
11739 * lisp.h (string_overflow): New decl.
11741 Fixups, following up to the user-interface timestamp change.
11742 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11743 for UI timestamps, instead of unsigned long.
11744 * msdos.c (mouse_get_pos): Likewise.
11745 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11746 * w32gui.h (Time): Define by including "systime.h" rather than by
11747 declaring it ourselves. (Bug#8664)
11749 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11750 * image.c (clear_image_cache): Likewise.
11752 * term.c (term_mouse_position): Don't assume time_t wraparound.
11754 Be more systematic about user-interface timestamps.
11755 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11756 and sometimes 'EMACS_UINT', to represent these timestamps.
11757 This change causes it to use 'Time' uniformly, as that's what X uses.
11758 This makes the code easier to follow, and makes it easier to catch
11759 integer overflow bugs such as Bug#8664.
11760 * frame.c (Fmouse_position, Fmouse_pixel_position):
11761 Use Time, not unsigned long, for user-interface timestamps.
11762 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11763 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11764 * keyboard.h (last_event_timestamp): Likewise.
11765 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11766 * menu.h (xmenu_show): Likewise.
11767 * term.c (term_mouse_position): Likewise.
11768 * termhooks.h (struct input_event.timestamp): Likewise.
11769 (struct terminal.mouse_position_hook): Likewise.
11770 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11771 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11772 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11773 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11774 what it was before.
11775 * menu.h, termhooks.h: Include "systime.h", for Time.
11777 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11778 Don't assume that the difference between two unsigned long values
11779 can fit into an integer. At this point, we know button_down_time
11780 <= event->timestamp, so the difference must be nonnegative, so
11781 there's no need to cast the result if double-click-time is
11782 nonnegative, as it should be; check that it's nonnegative, just in
11783 case. This bug is triggered when events are more than 2**31 ms
11784 apart (about 25 days). (Bug#8664)
11786 * xselect.c (last_event_timestamp): Remove duplicate decl.
11787 (x_own_selection): Remove needless cast to unsigned long.
11789 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11790 that always fit in int. Use a sentinel instead of a counter, to
11791 avoid a temp and to allay GCC's concerns about possible int overflow.
11792 * frame.h (struct frame): Use int for menu_bar_items_used
11793 instead of EMACS_INT, since it always fits in int.
11795 * menu.c (grow_menu_items): Check for int overflow.
11797 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11799 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11800 Before, the code was not consistent. These values cannot exceed
11801 2**31 - 1 so there's no need to make them unsigned.
11802 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11803 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11804 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11806 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11808 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11809 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11810 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11811 presumably because the widths might not match.
11813 * window.c (size_window): Avoid needless test at loop start.
11815 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11817 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11819 2011-05-12 Drew Adams <drew.adams@oracle.com>
11821 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11823 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11825 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11826 `width' to `bar_area_x' and `bar_area_width', respectively.
11827 (x_scroll_run): Take account of fringe background extension.
11829 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11830 Rename local vars `left' and `width' to `bar_area_x' and
11831 `bar_area_width', respectively.
11832 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11833 background extension.
11835 2011-05-10 Jim Meyering <meyering@redhat.com>
11837 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11839 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11841 * image.c (Finit_image_library): Return t for built-in image types,
11842 like pbm and xbm. (Bug#8640)
11844 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11846 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11848 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11850 * w32console.c (Fset_screen_color): Doc fix.
11851 (Fget_screen_color): New function.
11852 (syms_of_ntterm): Defsubr it.
11854 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11855 unlink the temporary file if Fcall_process didn't create it in the
11857 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11858 child process will be redirected to a file specified with `:file'.
11859 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11860 cue to call_process_cleanup not to close that handle.
11862 2011-05-07 Ben Key <bkey76@gmail.com>
11864 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11865 one of two shell specific rules, either bootstrap-temacs-CMD or
11866 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11867 to the previous implementation of the bootstrap-temacs rule.
11868 The bootstrap-temacs-CMD rule is similar to the previous
11869 implementation of the bootstrap-temacs rule except that it
11870 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11873 These changes, along with some changes to nt/configure.bat,
11874 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11875 earlier fix to add support for --cflags and --ldflags options
11876 that include quotes so that it works whether make uses cmd or
11879 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11881 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11882 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11884 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11885 a string. Handle both cases.
11886 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11887 (Fdbus_register_method): Use Qinvalid_function.
11889 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11891 * makefile.w32-in: Update dependencies.
11892 (LISP_H): Add inttypes.h and stdin.h.
11893 (PROCESS_H): Add unistd.h.
11895 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11897 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11898 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11900 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11902 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11904 * term.c (vfatal): Remove stray call to va_end.
11905 It's not needed and the C Standard doesn't allow it here anyway.
11907 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11908 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11910 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11913 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11915 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11917 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11919 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11921 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11923 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11924 * charset.c (Fdefine_charset_internal): Don't initialize
11925 charset.code_space[15]. The value was garbage, on hosts with
11926 32-bit int (Bug#8600).
11928 * lread.c (read_integer): Be more consistent with string-to-number.
11929 Use string_to_number to do the actual conversion; this avoids
11930 rounding errors and fixes some other screwups. Without this fix,
11931 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11932 (digit_to_number): Move earlier, for benefit of read_integer.
11933 Return -1 if the digit is out of range for the base, -2 if it is
11934 not a digit in any supported base. (Bug#8602)
11936 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11938 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11939 to match comment at start of function. This also removes a
11940 GCC warning about overflow in a 32+64-bit port.
11942 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11944 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11945 Reported by Stefan Monnier in
11946 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11947 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11948 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11950 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11951 (EMACS_UINTPTR): Likewise, with uintptr_t.
11953 * lisp.h: Prefer 64-bit EMACS_INT if available.
11954 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11955 on 32-bit hosts that have 64-bit int, so that they can access
11957 However, temporarily disable this change unless the temporary
11958 symbol WIDE_EMACS_INT is defined.
11960 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11962 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11963 This removes an assumption that EMACS_INT and long are the same
11964 width as pointers. The assumption is true for Emacs porting targets
11965 now, but we want to make other targets possible.
11966 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11967 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11968 In the rest of the code, change types of integers that hold casted
11969 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11970 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11971 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11972 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11973 No need to cast type when ORing.
11974 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11975 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11976 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11977 assume EMACS_INT is the same width as char *.
11978 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11979 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11980 Remove no-longer-needed casts.
11981 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11982 (xg_tool_bar_help_callback, xg_make_tool_item):
11983 Use EMACS_INTPTR to hold an integer
11984 that will be cast to void *; this can avoid a GCC warning
11985 if EMACS_INT is not the same width as void *.
11986 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11987 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11988 (current_message_1, set_message_1):
11989 Use a local to convert to proper width without a cast.
11990 * xmenu.c (dialog_selection_callback): Likewise.
11992 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11993 Also, don't assume VALBITS / RAND_BITS is less than 5,
11994 and don't rely on undefined behavior when shifting a 1 left into
11996 * lisp.h (get_random): Change signature to match.
11998 * lread.c (hash_string): Use size_t, not int, for hash computation.
11999 Normally we prefer signed values; but hashing is special, because
12000 it's better to use unsigned division on hash table sizes so that
12001 the remainder is nonnegative. Also, size_t is the natural width
12002 for hashing into memory. The previous code used 'int', which doesn't
12003 retain enough info to hash well into very large tables.
12004 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12006 * dbusbind.c: Don't possibly lose pointer info when converting.
12007 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12008 Use XPNTR rather than XHASH, so that the high-order bits of
12009 the pointer aren't lost when converting through void *.
12011 * eval.c (Fautoload): Don't double-shift a pointer.
12013 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12015 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12017 * gnutls.c (DEF_GNUTLS_FN):
12018 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12020 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12022 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12025 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12027 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12028 New version that can reserve upto 2GB of heap space.
12030 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12032 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12034 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12036 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12037 `gnutls_certificate_set_x509_key_file'.
12039 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12041 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12042 Update dependencies.
12044 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12046 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12047 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12048 Remove unused parameter `fildes'.
12049 * process.c (read_process_output, send_process): Don't pass it.
12051 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12053 Fix previous change: the library cache is defined in w32.c.
12054 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12055 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12057 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12059 Implement dynamic loading of GnuTLS on Windows.
12061 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12062 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12063 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12066 * gnutls.c (Qgnutls_dll): Define.
12067 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12068 (gnutls_*): Declare function pointers.
12069 (init_gnutls_functions): New function to initialize function pointers.
12070 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12071 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12072 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12073 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12074 (emacs_gnutls_write, emacs_gnutls_read)
12075 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12076 (Fgnutls_available_p): New function.
12077 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12078 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12079 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12081 * image.c: Include w32.h.
12082 (Vimage_type_cache): Delete.
12083 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12084 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12085 (w32_delayed_load): Move to w32.c.
12087 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12089 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12090 (w32_delayed_load): Move from image.c. When loading a library, record
12091 its filename in the :loaded-from property of the library id.
12092 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12093 Initialize and staticpro them.
12094 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12096 * process.c: Include lisp.h before w32.h, not after.
12097 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12098 instead of gnutls_record_check_pending.
12100 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12102 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12104 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12105 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12108 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12110 * xterm.c (x_set_frame_alpha): Do not set property on anything
12111 else than FRAME_X_OUTER_WINDOW (Bug#8608).

12131 * callproc.c: Indentation fixup.
12133 * sysdep.c (wait_for_termination_1): Make static.
12134 (wait_for_termination, interruptible_wait_for_termination):
12135 Move after wait_for_termination_1.
12137 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12139 * sysdep.c (interruptible_wait_for_termination): New function
12140 which is like wait_for_termination, but allows keyboard
12143 * callproc.c (Fcall_process): Add (:file "file") as an option for
12145 (Fcall_process_region): Ditto.
12147 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12149 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12150 rather than `XVECTOR (FOO)->size'.
12152 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12153 inttypes.h, as a gnulib replacement is used if it not available in
12156 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12158 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12159 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12160 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12162 * coding.c (coding_alloc_by_realloc): Error out if destination
12163 will grow beyond MOST_POSITIVE_FIXNUM.
12164 (decode_coding_emacs_mule): Abort if there isn't enough place in
12165 charbuf for the composition carryover bytes. Reserve an extra

12173 aborting when %lld or %lll format is passed.
12174 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12175 %llo or %llx format is passed. (Bug#8545)
12177 * window.c (window_scroll_line_based): Use a marker instead of
12178 simple variables to record original value of point. (Bug#7952)
12180 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12181 produced by %s or %c overflows available buffer space. (Bug#8545)
12183 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12185 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12186 (SIZE_MAX): Move defn after all includes, as they might #define it.
12188 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12190 * w32.c (init_environment): Warn about defaulting HOME to C:\.

12208 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12210 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12212 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12214 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12216 * makefile.w32-in: Update dependencies.
12218 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12220 Improve `doprnt' and its usage. (Bug#8545)
12221 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12222 `format_end'. Remove support for %l as a conversion specifier.
12223 Don't use xrealloc. Improve diagnostics when the %l size modifier
12224 is used. Update the commentary.
12226 * eval.c (verror): Simplify calculation of size_t.
12228 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12231 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12233 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12236 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12238 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12239 This makes this file independent of the recent pseudovector change.
12241 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12243 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12245 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12246 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12247 Remove unused local.
12248 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12250 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12251 GCC 4.6.0 optimizes based on type-based alias analysis.
12252 For example, if b is of type struct buffer * and v of type struct
12253 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12254 != &v->size, and therefore "v->size = 1; b->size = 2; return
12255 v->size;" must therefore return 1. This assumption is incorrect
12256 for Emacs, since it type-puns struct Lisp_Vector * with many other
12257 types. To fix this problem, this patch adds a new type struct
12258 vectorlike_header that documents the constraints on layout of vectors
12259 and pseudovectors, and helps optimizing compilers not get fooled
12260 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12261 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12262 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12264 (XSETPVECTYPE): Rewrite in terms of new macro.
12265 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12266 This is a bit clearer, and further avoids the possibility of
12267 undesirable aliasing.
12268 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12269 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12270 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12271 since Lisp_Subr is a special case (no "next" field).
12272 (ASIZE): Now uses header.size rather than size.
12273 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12274 to avoid the hassle of writing XVECTOR (foo)->header.size.
12275 (struct vectorlike_header): New type.
12276 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12277 object, to help avoid aliasing.
12278 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12279 (SUBRP): Likewise, since Lisp_Subr is a special case.
12280 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12281 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12282 (struct Lisp_Hash_Table): Combine first two members into a single
12283 struct vectorlike_header member. All uses of "size" and "next" members
12284 changed to be "header.size" and "header.next".
12285 * buffer.h (struct buffer): Likewise.
12286 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12287 * frame.h (struct frame): Likewise.
12288 * process.h (struct Lisp_Process): Likewise.
12289 * termhooks.h (struct terminal): Likewise.
12290 * window.c (struct save_window_data, struct saved_window): Likewise.
12291 * window.h (struct window): Likewise.
12292 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12293 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12294 * buffer.c (init_buffer_once): Likewise.
12295 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12297 * process.c (Fformat_network_address): Use local var for size,
12300 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12302 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12303 * data.c (atof): Remove decl; no longer used or needed.
12304 (digit_to_number): Move to lread.c.
12305 (Fstring_to_number): Use new string_to_number function, to be
12306 consistent with how the Lisp reader treats infinities and NaNs.
12307 Do not assume that floating-point numbers represent EMACS_INT
12308 without losing information; this is not true on most 64-bit hosts.
12309 Avoid double-rounding errors, by insisting on integers when
12310 parsing non-base-10 numbers, as the documentation specifies.
12311 * lisp.h (string_to_number): New decl, replacing ...
12312 (isfloat_string): Remove.
12313 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12314 (read1): Do not accept +. and -. as integers; this
12315 appears to have been a coding error. Similarly, do not accept
12316 strings like +-1e0 as floating point numbers. Do not report
12317 overflow for integer overflows unless the base is not 10 which
12318 means we have no simple and reliable way to continue.
12319 Break out the floating-point parsing into a new
12320 function string_to_number, so that Fstring_to_number parses
12321 floating point numbers consistently with the Lisp reader.
12322 (digit_to_number): Move here from data.c. Make it static inline.
12323 (E_CHAR, EXP_INT): Remove, replacing with ...
12324 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12325 (string_to_number): New function, replacing isfloat_string.
12326 This function checks for valid syntax and produces the resulting
12327 Lisp float number too. Rework it so that string-to-number
12328 no longer mishandles examples like "1.0e+". Use strtoumax,
12329 so that overflow for non-base-10 numbers is reported only when
12330 there's no portable and simple way to convert to floating point.
12332 * textprop.c (set_text_properties_1): Rewrite for clarity,
12333 and to avoid GCC warning about integer overflow.
12335 * intervals.h (struct interval): Use EMACS_INT for members
12336 where EMACS_UINT might cause problems. See
12337 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12338 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12339 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12341 (offset_intervals): Tell GCC not to worry about length overflow
12342 when negating a negative length.
12344 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12345 (overrun_check_free): Likewise.
12347 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12348 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12351 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12352 (gnutls_make_error): Rename local to avoid shadowing.
12353 (gnutls_emacs_global_deinit): ifdef out; not used.
12354 (Fgnutls_boot): Use const for pointer to readonly storage.
12355 Comment out unused local. Fix pointer signedness problems.
12357 * lread.c (openp): Don't stuff size_t into an 'int'.
12358 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12359 about possible signed overflow.
12361 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12362 (GDK_KEY_g): Don't define if already defined.
12363 (xg_prepare_tooltip): Avoid pointer signedness problem.
12364 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12366 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12367 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12369 * xfns.c (Fx_window_property): Simplify a bit,
12370 to make a bit faster and to avoid GCC 4.6.0 warning.
12371 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12373 * fns.c (internal_equal): Don't assume size_t fits in int.
12375 * alloc.c (compact_small_strings): Tighten assertion a little.
12377 Replace pEd with more-general pI, and fix some printf arg casts.
12378 * lisp.h (pI): New macro, generalizing old pEd macro to other
12379 conversion specifiers. For example, use "...%"pI"d..." rather
12380 than "...%"pEd"...".
12381 (pEd): Remove. All uses replaced with similar uses of pI.
12382 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12383 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12384 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12385 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12386 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12387 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12388 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12390 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12391 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12392 * print.c (safe_debug_print, print_object): Likewise.
12393 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12395 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12396 avoiding the 0 flag, which is not portable.
12397 * process.c (Fmake_network_process): Use pI to avoid cast.
12398 * region-cache.c (pp_cache): Likewise.
12399 * xdisp.c (decode_mode_spec): Likewise.
12400 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12401 behavior on 64-bit hosts with printf arg.
12402 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12403 (x_stop_queuing_selection_requests): Likewise.
12404 (x_get_window_property): Don't truncate byte count to an 'int'
12407 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12408 here, since it parses constructs like leading '-' and spaces,
12409 which are not wanted; and it overflows with large numbers.
12410 Instead, simply match F[0-9]+, which is what is wanted anyway.
12412 * alloc.c: Remove unportable assumptions about struct layout.
12413 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12414 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12415 (allocate_vectorlike, make_pure_vector): Use the new macros,
12416 plus offsetof, to remove unportable assumptions about struct layout.
12417 These assumptions hold on all porting targets that I know of, but
12418 they are not guaranteed, they're easy to remove, and removing them
12419 makes further changes easier.
12421 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12422 This doesn't fix a bug but makes the code clearer.
12423 (string_overrun_cookie): Now const. Use initializers that
12424 don't formally overflow signed char, to avoid warnings.
12425 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12426 can cause Emacs to crash when string overrun checking is enabled.
12427 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12428 multiple of sizeof (EMACS_INT); it need not be, if
12429 alignof(EMACS_INT) < sizeof (EMACS_INT).
12430 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12432 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12434 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12436 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12438 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12439 supposed to be handshaking. (Bug#8556)
12440 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12442 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12444 * lisp.h (Qdebug): List symbol.
12445 * eval.c (Qdebug): Restore global linkage.

12447 (handle_user_signal): Break into debugger when debug-on-event
12448 matches the current signal symbol.
12450 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12452 * alloc.c (check_sblock, check_string_bytes)
12453 (check_string_free_list): Convert to standard C.
12455 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12457 * w32.c (emacs_gnutls_push): Fix typo.
12459 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12461 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12462 "cast to pointer from integer of different size".
12464 Improve doprnt and its use in verror. (Bug#8545)
12465 * doprnt.c (doprnt): Document the set of format control sequences
12466 supported by the function. Use SAFE_ALLOCA instead of always
12469 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12470 is one byte too soon. Don't use xrealloc; instead xfree and
12473 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12475 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12478 * gnutls.c: Renamed global_initialized to
12479 gnutls_global_initialized. Added internals for the
12480 :verify-hostname-error, :verify-error, and :verify-flags
12481 parameters of `gnutls-boot' and documented those parameters in the
12482 docstring. Start callback support.
12483 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12484 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12485 on error. Return error code.
12486 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12487 (emacs_gnutls_read): Likewise.
12488 (Fgnutls_boot): Return handshake error code.
12489 (emacs_gnutls_handle_error): New function.
12490 (wsaerror_to_errno): Likewise.

12500 * process.c (wait_reading_process_output): Check if GnuTLS
12501 buffered some data internally if no FDs are set for TLS
12504 * makefile.w32-in (OBJ2): Add gnutls.$(O).

12552 <char-direction-table>: Deleted.
12554 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12556 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12557 * doprnt.c: Include limits.h.
12558 (SIZE_MAX): New macro.
12559 (doprnt): Return a size_t value. 2nd arg is now size_t.
12560 Many local variables are now size_t instead of int or unsigned.
12561 Improve overflow protection. Support `l' modifier for integer
12562 conversions. Support %l conversion. Don't assume an EMACS_INT
12563 argument for integer conversions and for %c.
12565 * lisp.h (doprnt): Restore prototype.
12567 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12568 $(SRC)/character.h.
12570 * Makefile.in (base_obj): Add back doprnt.o.
12572 * deps.mk (doprnt.o): Add back prerequisites.
12573 (callint.o): Depend on character.h.
12575 * eval.c (internal_lisp_condition_case): Include the handler
12576 representation in the error message.
12577 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12578 when breaking from the loop.
12580 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12582 * callint.c (Fcall_interactively): When displaying error message
12583 about invalid control letter, pass the character's codepoint, not
12584 a pointer to its multibyte form. Improve display of the character
12585 in octal and display also its hex code.
12587 * character.c (char_string): Use %x to display the (unsigned)
12588 codepoint of an invalid character, to avoid displaying a bogus
12591 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12592 `error', not SYMBOL_NAME itself.
12594 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12595 character arguments to `error'.
12597 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12598 to `error' in error message about FINAL_CHAR argument. Make sure
12599 FINAL_CHAR is a character, and use %c when it is passed as
12600 argument to `error'.
12602 2011-04-23 Eli Zaretskii <eliz@gnu.org>

12789 * nsfont.m: Fixed bugs in ns_get_family and
12790 ns_descriptor_to_entity that were caused by using free to
12791 deallocate memory blocks that were allocated by xmalloc (via
12792 xstrdup). This caused Emacs to crash when compiled with
12793 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12794 --enable-checking=xmallocoverrun). xfree is now used to
12795 deallocate these memory blocks.

12812 (emacs_read, emacs_write): Use it.
12813 * process.c (send_process): Adjust to the new signatures of
12814 emacs_write and emacs_gnutls_write. Do not attempt to store

13140 * category.h: ... from here.
13141 * category.c (check_category_table, set_category_set): Now static.
13143 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
13144 * lisp.h: Remove these decls.
13146 * buffer.c (buffer_count): Remove unused var.
13148 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
13149 so that it's not optimized away.
13150 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13151 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13152 exported only to the debugger.
13154 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
13155 * atimer.h (run_all_atimers): Remove; not exported.
13157 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13158 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13159 was inaccessible from Lisp.
13160 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13161 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13163 alloc.c: Import and export fewer symbols, and remove unused items.
13164 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13166 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13167 it's not optimized away by whole-program optimization.
13168 (message_enable_multibyte, free_misc): Remove.
13169 (catchlist, handlerlist, mark_backtrace):
13170 Declare only if BYTE_MARK_STACK.
13171 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
13172 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.

13179 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13180 (mark_backtrace): Define only if BYTE_MARK_STACK.
13181 * xdisp.c (message_enable_multibyte): Now static.
13183 Declare Lisp_Object Q* variables to be 'static' if not exported.
13184 This makes it easier for human readers (and static analyzers)
13185 to see whether these variables are used from other modules.
13186 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13187 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13188 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

13191 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
13192 * xmenu.c, xselect.c:
13193 Declare Q* vars static if they are not used in other modules.

13195 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
13196 Remove decls of unexported vars.
13197 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13199 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13201 Make Emacs functions such as Fatom 'static' by default.
13202 This makes it easier for human readers (and static analyzers)
13203 to see whether these functions can be called from other modules.
13204 DEFUN now defines a static function. To make the function external
13205 so that it can be used in other C modules, use the new macro DEFUE.
13206 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13207 (Finit_image_library):
13208 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13209 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13210 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13211 Remove decls, since these functions are now static.
13212 (Funintern, Fget_internal_run_time): New decls, since these functions
13213 were already external.
13215 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13216 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13222 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13223 Mark functions with DEFUE instead of DEFUN,
13224 if they are used in other modules.
13225 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13226 decls for now-static functions.
13227 * buffer.h (Fdelete_overlay): Remove decl.
13228 * callproc.c (Fgetenv_internal): Mark as internal.
13229 * composite.c (Fremove_list_of_text_properties): Remove decl.

13236 * fileio.c (Fmake_symbolic_link): New forward static decl.
13237 * image.c (Finit_image_library): New forward static decl.
13238 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13239 * intervals.h (Fprevious_property_change):
13240 (Fremove_list_of_text_properties): Remove decls.
13241 * keyboard.c (Fthis_command_keys): Remove decl.
13242 (Fcommand_execute): New forward static decl.

13258 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13260 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13263 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13265 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13266 when at ZV. (Bug#8487)
13268 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13270 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13272 * keyboard.c (parse_tool_bar_item): Likewise.
13273 * sound.c (sound_cleanup, alsa_close): Likewise.
13274 * termcap.c (tgetent): Likewise.
13275 * xfns.c (x_default_font_parameter): Likewise.
13276 * xsettings.c (read_and_apply_settings): Likewise.
13278 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13279 (overrun_check_free): Protoize.
13281 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13283 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13284 since callers should never pass a negative size.
13285 Change the signature to match that of plain 'read' and 'write'; see
13286 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13287 * lisp.h: Update prototypes of emacs_write and emacs_read.
13289 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13291 * xdisp.c (redisplay_window): Don't try to determine the character
13292 position of the scroll margin if the window start point w->startp
13293 is outside the buffer's accessible region. (Bug#8468)
13295 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13297 Fix write-region and its subroutines for buffers > 2GB.
13298 * fileio.c (a_write, e_write): Modify declaration of arguments and
13299 local variables to support buffers larger than 2GB.
13300 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13302 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13303 argument, local variables, and return value.
13305 * lisp.h: Update prototypes of emacs_write and emacs_read.
13307 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13309 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13311 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13313 Fix more problems found by GCC 4.6.0's static checks.
13315 * xdisp.c (vmessage): Use a better test for character truncation.
13317 * charset.c (load_charset_map): <, not <=, for optimization,
13318 and to avoid potential problems with integer overflow.
13319 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13320 * casetab.c (set_identity, shuffle): Likewise.
13321 * editfns.c (Fformat): Likewise.
13322 * syntax.c (skip_chars): Likewise.
13324 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13325 This also lets GCC 4.6.0 generate slightly better loop code.
13327 * callint.c (Fcall_interactively): <, not <=, for optimization.
13328 (Fcall_interactively): Count the number of arguments produced,
13329 not the number of arguments given. This is simpler and lets GCC
13330 4.6.0 generate slightly better code.
13332 * ftfont.c: Distingish more carefully between FcChar8 and char.
13333 The previous code passed unsigned char * to a functions like
13334 strlen and xstrcasecmp that expect char *, which does not
13335 conform to the C standard.
13336 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13337 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13338 char * when the C standard requires it.
13340 * keyboard.c (read_char): Remove unused var.
13342 * eval.c: Port to Windows vsnprintf (Bug#8435).
13343 Include <limits.h>.
13344 (SIZE_MAX): Define if the headers do not.
13345 (verror): Do not give up if vsnprintf returns a negative count.
13346 Instead, grow the buffer. This ports to Windows vsnprintf, which
13347 does not conform to C99. Problem reported by Eli Zaretskii.
13348 Also, simplify the allocation scheme, by avoiding the need for
13349 calling realloc, and removing the ALLOCATED variable.
13351 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13353 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13354 But keep the doprint source code for now, as we might revamp it
13355 and use it again (Bug#8435).
13356 * lisp.h (doprnt): Remove.
13357 * Makefile.in (base_obj): Remove doprnt.o.
13358 * deps.mk (doprnt.o): Remove.
13360 error: Print 32- and 64-bit integers portably (Bug#8435).
13361 Without this change, on typical 64-bit hosts error ("...%d...", N)
13362 was used to print both 32- and 64-bit integers N, which relied on
13363 undefined behavior.
13364 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13365 * lisp.h (error, verror): Mark as printf-like functions.
13366 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13367 Report overflow in size calculations when allocating printf buffer.
13368 Do not truncate output string at its first null byte.
13369 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13370 Truncate the output at a character boundary, since vsnprintf does not
13372 * charset.c (check_iso_charset_parameter): Convert internal
13373 character to string before calling 'error', since %c now has the
13375 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13376 overflow when computing char to be passed to 'error'. Do not
13377 pass Lisp_Object to 'error'; pass the integer instead.
13378 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13379 formatted with plain %d.
13381 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13383 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13385 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13387 * xterm.c (x_catch_errors): Remove duplicate declaration.
13389 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13391 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13393 2011-04-10 Jim Meyering <meyering@redhat.com>
13395 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13396 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13397 return ssize_t not "int", and use size_t as the buffer length.
13398 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13399 * gnutls.h: Update declarations.
13400 * process.c (read_process_output): Use ssize_t, to match.
13401 (send_process): Likewise.
13403 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13405 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13407 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13409 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13410 Use unsigned char, to match FcChar8 type definition.
13412 * xterm.c (handle_one_xevent):
13413 * xmenu.c (create_and_show_popup_menu):
13414 * xselect.c (x_decline_selection_request)
13415 (x_reply_selection_request): Avoid type-punned deref of X events.
13417 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13419 Fix some uses of `int' instead of EMACS_INT.
13420 * search.c (string_match_1, fast_string_match)
13421 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13422 (scan_buffer, find_next_newline_no_quit)
13423 (find_before_next_newline, search_command, Freplace_match)
13424 (Fmatch_data): Make some `int' variables be EMACS_INT.
13426 * xdisp.c (display_count_lines): 3rd argument and return value now
13427 EMACS_INT. All callers changed.
13428 (pint2hrstr): Last argument is now EMACS_INT.
13430 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13431 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13432 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13433 (decode_coding_utf_16, decode_coding_emacs_mule)

13435 (decode_coding_ccl, decode_coding_charset)
13436 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13437 (decode_coding_iso_2022, decode_coding_emacs_mule)
13438 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13439 <char_offset, last_offset>: Declare EMACS_INT.

13441 (encode_coding_emacs_mule, encode_invocation_designation)
13442 (encode_designation_at_bol, encode_coding_iso_2022)
13443 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13444 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13446 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13447 (encode_invocation_designation): Last argument P_NCHARS is now
13449 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13450 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13452 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13455 * ccl.c (Fccl_execute_on_string): Declare some variables
13458 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13460 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13462 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13464 * process.c (Fformat_network_address): Doc fix.
13466 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13468 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13470 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13472 * keyboard.c (read_char): Call Lisp function help-form-show,
13473 instead of using internal_with_output_to_temp_buffer.
13474 (Qhelp_form_show): New var.
13475 (syms_of_keyboard): Use DEFSYM macro.
13477 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13479 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13481 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13483 * process.c (Flist_processes): Remove to Lisp.
13484 (list_processes_1): Delete.
13486 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13488 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13490 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13492 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13494 Fix more problems found by GCC 4.6.0's static checks.
13496 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13498 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13500 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13502 * xdisp.c (vmessage): Mark as a printf-like function.
13504 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13506 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13508 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13509 printf-like functions.
13510 (tiff_load): Add casts to remove these marks before passing them
13511 to system-supplied API.
13513 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13515 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13516 This avoids several warnings with gcc -Wstrict-overflow.
13517 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13518 directly, rather than having caller test rule sign. This avoids
13519 some unnecessary tests.
13520 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13521 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13522 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13524 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13525 (xfont_open): Avoid unnecessary tests.
13527 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13529 * composite.h, composite.c (composition_gstring_put_cache):
13530 Use EMACS_INT, not int, for length.
13532 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13533 breaking out part of COMPOSITION_DECODE_RULE.
13534 (COMPOSITION_DECODE_RULE): Use it.
13535 * composite.c (get_composition_id): Remove unused local vars,
13536 by using the new macro.
13538 * textprop.c (set_text_properties_1): Change while to do-while,
13539 since the condition is always true at first.
13541 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13542 (interval_deletion_adjustment): Return unsigned value.
13545 * process.c (list_processes_1, create_pty, read_process_output):

13547 (create_pty): Remove unnecessary "volatile"s.
13548 (Fnetwork_interface_info): Avoid possibility of int overflow.

13561 * print.c (print_error_message): Avoid int overflow.
13563 * font.c (font_list_entities): Redo for clarity,
13564 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

13579 (wordify): Omit three unnecessary tests.
13581 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

13586 * dired.c (file_name_completion): Remove var that is set but not used.
13588 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13590 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13591 (Finsert_file_contents): Remove unnecessary code checking fd.
13593 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13594 Check for integer overflow on size calculations.
13596 * buffer.c (Fprevious_overlay_change): Remove var that is set
13599 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13600 Remove vars that are set but not used.
13601 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13602 (timer_check_2): Mark vars as initialized.
13604 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13606 * image.c (lookup_image): Remove var that is set but not used.
13607 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13609 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13610 that are set but not used.
13612 * xfns.c (make_invisible_cursor): Don't return garbage
13613 if XCreateBitmapFromData fails (Bug#8410).
13615 * xselect.c (x_get_local_selection, x_handle_property_notify):
13616 Remove vars that are set but not used.
13618 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13619 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13621 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13622 Remove var that is set but not used.
13623 (scroll_bar_windows_size): Now size_t, not int.
13624 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13625 Check for overflow.
13627 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13628 (map_tty_color) [!defined MSDOS]: Likewise.
13630 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13632 * coding.c: Remove vars that are set but not used.
13633 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13634 All callers changed.
13635 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13636 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13637 (decode_coding_charset): Remove vars that are set but not used.
13639 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13640 that is set but not used.
13642 * print.c (print_object): Remove var that is set but not used.
13644 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13645 The gnulib version avoids calling malloc in the usual case,
13646 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13647 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13648 * filelock.c (current_lock_owner): Likewise.
13649 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13650 * sysdep.c: Include allocator.h, careadlinkat.h.
13651 (emacs_no_realloc_allocator): New static constant.
13652 (emacs_readlink): New function.
13653 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13654 ../lib/careadlinkat.h.
13656 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13658 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13659 first non-nil return value).

13668 * xdisp.c (display_count_lines): Remove parameter `start',
13669 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13670 (get_char_face_and_encoding): Remove parameter `multibyte_p',

13673 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13674 and thereabouts. All callers changed.
13675 (get_per_char_metric): Remove parameter `f', unused since
13676 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13678 2011-04-02 Jim Meyering <meyering@redhat.com>
13680 do not dereference NULL upon failed strdup
13681 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13682 (ns_get_family): Likewise.
13684 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13686 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13688 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13690 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13693 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13695 Add lexical binding.
13697 * window.c (Ftemp_output_buffer_show): New fun.
13698 (Fsave_window_excursion):
13699 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13701 * lread.c (lisp_file_lexically_bound_p): New function.
13702 (Fload): Bind Qlexical_binding.
13703 (readevalloop): Remove `evalfun' arg.
13704 Bind Qinternal_interpreter_environment.
13705 (Feval_buffer): Bind Qlexical_binding.
13706 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13708 (syms_of_lread): Declare `lexical-binding'.
13710 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13712 * keyboard.c (eval_dyn): New fun.
13713 (menu_item_eval_property): Use it.
13715 * image.c (parse_image_spec): Use Ffunctionp.
13717 * fns.c (concat, mapcar1): Accept byte-code-functions.
13719 * eval.c (Fsetq): Handle lexical vars.
13720 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13721 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13722 (FletX, Flet): Obey lexical binding.
13723 (Fcommandp): Handle closures.
13724 (Feval): New `lexical' arg.
13725 (eval_sub): New function extracted from Feval. Use it almost
13726 everywhere where Feval was used. Look up vars in lexical env.
13728 (Ffunctionp): Move from subr.el.
13729 (Ffuncall): Handle closures.
13730 (apply_lambda): Remove `eval_flags'.
13731 (funcall_lambda): Handle closures and new byte-code-functions.
13732 (Fspecial_variable_p): New function.
13733 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13734 but without exporting it to Lisp.
13736 * doc.c (Fdocumentation, store_function_docstring):
13737 * data.c (Finteractive_form): Handle closures.
13739 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13742 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13744 (exec_byte_code): New function extracted from Fbyte_code to handle new
13745 calling convention for byte-code-functions. Add new byte-codes.
13747 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13749 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13751 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13753 * xdisp.c (redisplay_internal): Fix prototype.
13755 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13757 * xdisp.c (SCROLL_LIMIT): New macro.
13758 (try_scrolling): Use it when setting scroll_limit.
13759 Limit scrolling to 100 screen lines.
13760 (redisplay_window): Even when falling back on "recentering",
13761 position point in the window according to scroll-conservatively,
13762 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13764 (try_scrolling): When point is above the window, allow searching
13765 as far as scroll_max, or one screenful, to compute vertical
13766 distance from PT to the scroll margin position. This prevents
13767 try_scrolling from unnecessarily failing when
13768 scroll-conservatively is set to a value slightly larger than the
13769 window height. Clean up the case of PT below the margin at bottom
13770 of window: scroll_max can no longer be INT_MAX. When aggressive
13771 scrolling is in use, don't let point enter the opposite scroll
13772 margin as result of the scroll.
13773 (syms_of_xdisp) <scroll-conservatively>: Document the
13774 threshold of 100 lines for never-recentering scrolling.
13776 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13778 * dispextern.h (move_it_by_lines):

13781 (message_log_check_duplicate): Remove parameters `prev_bol' and
13782 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13783 (redisplay_internal): Remove parameter `preserve_echo_area',
13784 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13786 * indent.c (Fvertical_motion):
13787 * window.c (window_scroll_pixel_based, Frecenter):
13788 Don't pass `need_y_p' to `move_it_by_lines'.
13790 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13792 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13793 steal a few bits to be more compact.
13794 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13795 Remove unneeded casts.
13797 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13799 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13801 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13802 binding" message (bug#7967).
13804 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13806 Fix more problems found by GCC 4.6.0's static checks.
13808 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13809 Remove unused local var.
13811 * editfns.c (Fmessage_box): Remove unused local var.
13813 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13814 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13815 Omit unused local vars.
13816 * window.c (shrink_windows): Omit unused local var.
13817 * menu.c (digest_single_submenu): Omit unused local var.
13818 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13819 Omit unused local var.
13821 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13822 Don't assume string length fits in int.
13823 (keyremap_step, read_key_sequence): Use size_t for sizes.
13824 (read_key_sequence): Don't check last_real_key_start redundantly.
13826 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13827 instead of alloca (Bug#8344).
13829 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13830 (Fbacktrace_frame): Don't assume nframes fits in int.
13832 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

13837 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13839 * cm.c (calccost): Turn while-do into do-while, for clarity.
13841 * keyboard.c (syms_of_keyboard): Use the same style as later
13842 in this function when indexing through an array. This also
13843 works around GCC bug 48267.
13845 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13847 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13849 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13850 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13852 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13853 This avoids undefined behavior on integer overflow, and is a bit
13854 more convenient anyway since it is compared to a size_t variable.
13856 Variadic C functions now count arguments with size_t, not int.
13857 This avoids an unnecessary limitation on 64-bit machines, which
13858 caused (substring ...) to crash on large vectors (Bug#8344).

13868 * fns.c (concat): Likewise.
13869 * frame.c (x_set_frame_parameters): Likewise.
13870 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13871 0 if not found, not -1. All callers changed.
13873 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13874 (stack_copy_size): Now size_t, not int.
13875 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13877 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13879 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13880 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13881 All callers changed.
13883 * lisp.h (multibyte_char_to_unibyte):
13884 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13885 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13896 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13897 don't set the hook to nil, but remove the offending function instead.
13898 (Qcommand_hook_internal): Remove, unused.
13899 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13900 Vcommand_hook_internal.
13902 * eval.c (enum run_hooks_condition): Remove.
13903 (funcall_nil, funcall_not): New functions.
13904 (run_hook_with_args): Call each function through a `funcall' argument.

13918 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13919 All callers changed.
13921 * w32.c (_wsa_errlist): Use braces for struct initializers.
13923 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13924 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13925 All callers changed.

14070 * term.c (Fsuspend_tty, Fresume_tty):
14071 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14072 * window.c (temp_output_buffer_show):

14080 * buffer.c (Fkill_all_local_variables):
14081 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14083 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14084 unconditionally since it does the check itself.
14086 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14088 Fix more problems found by GCC 4.5.2's static checks.
14090 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14091 the first time through the loop, since we know p0 < p1 then.
14092 This also avoids a gcc -Wstrict-overflow warning.
14094 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14095 leading to a memory leak, possible in functions like
14096 load_charset_map_from_file that can allocate an unbounded number
14097 of objects (Bug#8318).
14099 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14100 that could (at least in theory) be that large.
14102 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14103 This is less likely to overflow, and avoids undefined behavior if
14104 overflow does occur. All callers changed. Use strtoul to scan
14105 for the unsigned long integer.
14106 (pint2hrstr): Simplify and tune code slightly.
14107 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14117 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14120 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14122 * process.c (Fmake_network_process): Use socklen_t, not int,
14123 where POSIX says socklen_t is required in portable programs.
14124 This fixes a porting bug on hosts like 64-bit HP-UX, where
14125 socklen_t is wider than int (Bug#8277).
14126 (Fmake_network_process, server_accept_connection):
14127 (wait_reading_process_output, read_process_output):
14130 * process.c: Rename or move locals to avoid shadowing.

14140 Make tparam.h and terminfo.c consistent.
14141 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14142 Include tparam.h instead, since it declares them.
14143 * cm.h (PC): Remove extern decl; tparam.h now does this.
14144 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14145 * terminfo.c: Include tparam.h, to check interfaces.
14146 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14147 (tparam): Adjust signature to match interface in tparam.h;
14148 this removes some undefined behavior. Check that outstring and len
14149 are zero, which they always are with Emacs.
14150 * tparam.h (PC, BC, UP): New extern decls.
14152 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14153 (xftfont_open): Rename locals to avoid shadowing.
14155 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

14170 (find_automatic_composition, composition_adjust_point): Likewise.
14171 (composition_update_it): Mark var as initialized.
14172 (find_automatic_composition): Mark vars as initialized,
14173 with a FIXME (Bug#8290).

14177 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14178 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14179 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14180 to avoid shadowing.
14182 * textprop.c (property_change_between_p): Remove; unused.
14184 * intervals.c (interval_start_pos): Now static.
14186 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14192 Fix pointer signedness.
14193 (alsa_choose_format): Remove unused local var.
14194 (wav_play): Initialize a variable to 0, to prevent undefined
14195 behavior (Bug#8278).
14197 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14199 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14201 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14202 clobbering (Bug#8298).
14203 * sysdep.c (sys_subshell): Likewise.
14204 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14206 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14207 This should get cleaned up, so that child_setup has the
14208 same signature on all platforms.
14210 * callproc.c (call_process_cleanup): Now static.
14211 (relocate_fd): Rename locals to avoid shadowing.
14213 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14215 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14216 not to be necessary, and produces flickering.
14218 2011-03-20 Glenn Morris <rgm@gnu.org>
14220 * config.in: Remove file.
14222 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14224 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14225 are now in src/globals.h.

14252 (sigchld_handler): Now static.
14254 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14255 That way, the code declares only the vars that it needs.

14266 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14267 Define only if needed.
14269 * unexelf.c (unexec): Name an expression,
14270 to avoid gcc -Wbad-function-cast warning.
14271 Use a different way to cause a compilation error if anyone uses
14272 n rather than nn, a way that does not involve shadowing.
14273 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14275 * deps.mk (unexalpha.o): Remove; unused.
14277 New file unexec.h, the (simple) interface for unexec (Bug#8267).

14348 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
14351 * lisp.h (eassert): Check that the argument compiles, even if
14352 ENABLE_CHECKING is not defined.
14354 * data.c (Findirect_variable): Name an expression, to avoid
14355 gcc -Wbad-function-cast warning.

14372 (Fmemory_limit): Cast sbrk's returned value to char *.

14398 (RETALLOC_IF): Define only if needed.
14399 (WORDCHAR_P): Likewise. This one is never needed, but is used
14400 only in a comment talking about a compiler bug, so put inside
14401 the #if 0 of that comment.

14431 gcpro1, gcpro2, etc.
14432 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14434 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14435 argument, for consistency with GCPRO2_VAR, etc: it is now the

14439 Rename locals to avoid shadowing.
14441 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14442 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14443 dired.c's scmp function, had undefined behavior.
14444 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14445 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14446 * buffer.h: ... to here, because these macros use current_buffer,
14447 and the new implementation with inline functions needs to have
14448 current_buffer in scope now, rather than later when the macros
14450 (downcase, upcase1): New static inline functions.
14451 (DOWNCASE, UPCASE1): Reimplement using these functions.
14452 This avoids undefined behavior in expressions like

14493 * buffer.c (fix_overlays_before): Mark locals as initialized.
14494 (fix_start_end_in_overlays): Likewise. This function should be
14495 simplified by using pointers-to-pointers, but that's a different

14498 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14499 (report_overlay_modification): Rename locals to avoid shadowing.

14504 to suppress a gcc -Wclobbered warning that does not seem to be right.
14505 (MAXPATHLEN): Define only if needed.
14507 * process.c (serial_open, serial_configure): Move decls from here ...
14508 * systty.h: ... to here, so that they can be checked.
14510 * fns.c (get_random, seed_random): Move extern decls from here ...

14522 (describe_map_tree):
14523 Rename locals to avoid shadowing.
14525 * keyboard.c: Declare functions static if they are not used elsewhere.

14850 * coding.c (coding_set_source, coding_set_destination):

14852 for clarity, and to avoid gcc -Wempty-body warning.
14853 (Fdefine_coding_system_internal): Don't redeclare 'i' inside
14854 a block, when the outer 'i' will do.
14855 (decode_coding_utf_8, decode_coding_utf_16, detect_coding_emacs_mule):

14866 (decode_coding_emacs_mule): Mark variables that gcc
14867 -Wuninitialized does not deduce are never used uninitialized.
14868 (detect_coding_iso_2022): Initialize a local variable that might
14869 be used uninitialized. Leave a FIXME because it's not clear that
14870 this initialization is needed. (Bug#8211)
14871 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
14872 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

14903 Move these decls to tparam.h, and make them agree with what
14904 is actually in tparam.c. The previous trick of using incompatible
14905 decls in different modules does not conform to the C standard.
