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

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

89 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
90 Now constants, not macros.
92 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
94 Remove unnecessary casts involving pointers.

96 since they involve casting to or from void *.
97 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
98 (make_pure_float, make_pure_vector):
99 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

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

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

191 * composite.c (COMPOSITE_INLINE):
192 * dispnew.c (DISPEXTERN_INLINE):
193 * sysdep.c (SYSTIME_INLINE):
194 Define to EXTERN_INLINE, so that the corresponding functions
195 are compiled into code.
196 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
197 (INLINE_HEADER_END): New macros.
198 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

218 hard-coding the path separator.
220 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
222 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
223 This how ASET and AREF are supposed to work, and makes
224 it easier to think about future improvements. See
225 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
226 * charset.h (set_charset_attr): New function.
227 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
228 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

638 * alloc.c (listn): Fix the order the arguments are consed onto the
641 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
642 enumeration constants, as PURE and HEAP are too general, and clash
643 with other headers and sources, such as gmalloc.c and the
644 MS-Windows system headers. All users changed.
646 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

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

664 complains about the types in the unevaluated arm when the argument
665 is an integer literal.
666 (xgetint): Simplify expression.
667 * alloc.c (gdb_make_enums_visible): New constant. This ports to
668 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
669 Zaretskii in <http://bugs.gnu.org/12036#13>.
670 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer

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

730 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
731 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
732 not be usable in #if. This simplifies things.
734 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
736 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
738 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

741 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
742 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
743 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
744 Adjust to changes in lisp.h and emacs.c, by using
745 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
746 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
747 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
748 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
749 instead of gdb_valbits.
750 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
751 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
752 instead of gdb_array_mark_flag.
753 (xboolvector): Get size from $->size, not $->header.size.
754 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
755 (xreload, hook-run, hookpost-run): Remove.
756 * emacs.c: Include <verify.h>.
757 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
758 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
760 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
761 (gdb_USE_LSB_TAG): New enum constants.
762 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

765 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
766 as constants, so they're visible to GDB.

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

783 add argument, tune behavior, and adjust all callers.
785 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
787 Use typedef for EMACS_INT, EMACS_UINT.
788 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
789 than macros. This simplifies debugging in the usual case, since
790 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
791 and it allows expressions involving EMACS_INT casts.
792 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
794 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

807 * buffer.c (Fkill_buffer): Adjust indirection counters when the
808 buffer is definitely dead. This should really fix an issue reported
809 by Christoph Scholtes again. (Bug#12007).
810 (init_buffer_once): Initialize indirection counters of
811 buffer_defaults and buffer_local_symbols (for sanity and safety).
813 2012-07-24 Eli Zaretskii <eliz@gnu.org>
815 * xdisp.c (init_iterator): Don't compute dimensions of truncation
816 and continuation glyphs on tooltip frames, leave them at zero.
817 Avoids continued lines in tooltips. (Bug#11832)
819 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

847 * buffer.c (Fbuffer_swap_text): Swap indirections too.
848 This avoids crash reported by Christoph Scholtes at
849 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
851 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
853 * nsmenu.m (Popdown_data): New struct.
854 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
856 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

876 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
878 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
879 as it's limited by the amount of memory, not by INT_MAX.
881 2012-07-21 Eli Zaretskii <eliz@gnu.org>
883 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
884 in special-event-map. See the discussion at

1607 * s/aix4-2.h (unix): Remove; no longer needed.
1609 EMACS_TIME simplification (Bug#11875).
1610 This replaces macros (which typically do not work in GDB)

1612 The functional style also makes code easier to read and maintain.
1613 * systime.h: Include <sys/time.h> on all hosts, not just if
1614 WINDOWSNT, since 'struct timeval' is needed in general.

1630 (add_emacs_time, sub_emacs_time): New functions.
1631 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1654 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1655 Prefer snprintf to strncpy.
1656 * nsterm.m (ns_term_init):
1657 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1658 * nsterm.m (ns_term_init):
1659 Avoid the need for strncpy, by using build_string or
1660 make_unibyte_string directly. Use dtoastr, not snprintf.
1661 * process.c (Fmake_network_process): Diagnose service names that
1662 are too long, rather than silently truncating them or creating
1663 non-null-terminated names.
1664 (Fnetwork_interface_info): Likewise, for interface names.
1665 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1666 Prefer sprintf to strncat.

1680 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1681 where argument type is known to be a Lisp_Cons.

1738 Stop ns builds setting the EMACSLOADPATH environment variable.
1739 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1740 Now it does not set EMACSLOADPATH, just returns the load-path string.

1742 * lread.c [HAVE_NS]: Include nsterm.h.
1743 (init_lread) [HAVE_NS]: Use ns_load_path.

1753 (ns_init_paths): Do not set EMACSPATH.

1813 Move marker debugging code under MARKER_DEBUG.
1814 * marker.c (MARKER_DEBUG): Move marker debugging code under
1815 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1816 for bootstrap with --enable-checking (~3x slowdown reported
1817 by Juanma Barranquero <lekktu@gmail.com>).

1829 (display_line): Add commentary about displaying truncation glyphs
1831 (produce_special_glyphs): Move here from term.c.
1833 * term.c (produce_special_glyphs): Move to xdisp.c.
1835 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1838 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1840 * xdisp.c (display_line): Avoid warning about implicit declaration
1843 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1845 * lisp.h: Remove empty conditional.
1847 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1849 * lread.c (load_path_check): Now static.
1851 Fix some minor --with-ns problems found by static checking.
1852 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1853 (x_set_font) [!HAVE_X_WINDOWS]:
1854 * image.c (xpm_load_image) [HAVE_NS]:
1855 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1856 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1857 Remove unused local.
1858 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1859 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1860 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1861 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1862 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1863 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1864 Fix pointer signedness problem.
1865 * xfaces.c (FRAME_X_FONT_TABLE):
1866 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1868 2012-07-07 Glenn Morris <rgm@gnu.org>
1870 * lread.c (load_path_check): New function, split from init_lread.
1871 (init_lread): Reorganize. Motivation:
1872 If EMACSLOADPATH is set, check/warn about that rather than the
1873 defaults, which we are not going to use. Hence we can remove
1874 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1875 Don't warn if site-lisp directories are missing.
1876 If not installed, start from a blank load-path, since
1877 PATH_LOADSEARCH refers to the eventual installation directories.
1879 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1881 Support truncation and continuation glyphs on GUI frames, when
1882 fringes are disabled. (Bug#11832)
1883 * xdisp.c (init_iterator): Get dimensions of truncation and
1884 continuation glyphs even if on GUI frames. Adjust
1885 it->last_visible_x on GUI frames when the left or right fringes,
1886 or both, are absent.
1887 (start_display, move_it_in_display_line_to): Handle the case of a
1888 GUI frame without a fringe to display continuation or truncation
1890 (insert_left_trunc_glyphs): Support GUI frames: make sure
1891 truncation glyphs overwrite enough glyphs from the current line to
1892 have sufficient space in pixels.
1893 (display_line): Support truncation and continuation glyphs on GUI
1894 frames. If some spare pixels are left on the line after inserting
1895 the truncation glyphs, fill that space with a stretch glyph of a
1896 suitably computed width.
1898 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1899 produce_glyphs, to support GUI sessions.
1901 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1903 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1905 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1907 Do not require float-time's arg to fit in time_t (Bug#11825).
1908 This works better on hosts where time_t is unsigned, and where
1909 float-time is applied to the (negative) difference between two times.
1910 * editfns.c (decode_time_components): Last arg is now double *,
1911 not int *, and means to store all the result as a double, without
1912 worrying about whether the seconds part fits in time_t.
1913 All callers changed.
1914 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1915 All callers changed.
1916 (Ffloat_time): Do not fail merely because the specified time falls
1917 outside of time_t range.
1919 2012-07-07 Glenn Morris <rgm@gnu.org>
1921 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1922 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1923 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1925 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1927 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1928 Update dependencies.
1930 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1932 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1934 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1935 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1936 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1937 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1938 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1939 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1941 * xfont.c (compare_font_names): Redo to omit the need for casts.
1943 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1945 * xfns.c (Fx_change_window_property): Doc fix.
1946 * w32fns.c (Fx_change_window_property): Doc fix.
1948 * w32fns.c (Fx_window_property): Accept the same arguments as the
1949 X Windows version. Doc fix.
1950 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1952 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1953 Eli Zaretskii <eliz@gnu.org>
1955 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1956 Windows-specific code from nt/config.nt moved here.
1957 Obsolete settings removed.
1959 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1961 * process.c: Avoid unnecessary calls to gettime.
1962 (wait_reading_process_output): Don't get the time of day
1963 when gobbling data immediately and not waiting, as there's no need
1964 for it in that case. This removes a FIXME.
1966 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1968 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1969 is defined (Bug#11768).
1971 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1973 Fix marker debugging code.
1974 * marker.c (byte_char_debug_check): Do not perform the check
1975 if buffer is not multibyte.
1976 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1977 Call byte_char_debug_check with correct arguments.
1979 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1981 Compile marker debugging code only if ENABLE_CHECKING is defined.
1982 * marker.c (byte_char_debug_check, count_markers):
1983 Use only if ENABLE_CHECKING is defined.
1984 (byte_debug_flag): Remove.
1985 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1986 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1988 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1990 Avoid code repetition in marker-related functions.
1991 * marker.c (attach_marker): New function.
1992 (Fset_marker, set_marker_restricted, set_marker_both)
1993 (set_marker_restricted_both): Use it.
1994 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1995 Consistently rename charno to charpos.
1996 (marker_position): Add eassert.
1997 (marker_byte_position): Convert to eassert.
1999 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2001 Simplify list operations in unchain_overlay and unchain_marker.
2002 * buffer.c (unchain_overlay): Simplify. Add comment.
2003 * marker.c (unchain_marker): Simplify. Fix comments.
2005 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2007 Introduce fast path for the widely used marker operation.
2008 * alloc.c (build_marker): New function.
2009 * lisp.h (build_marker): New prototype.
2010 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
2011 * composite.c (autocmp_chars): Likewise.
2012 * editfns.c (buildmark): Remove.
2013 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2014 (save_restriction_save): Use build_marker.
2015 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2016 * window.c (save_window_save): Likewise.
2018 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2020 Do not use Fdelete_overlay in delete_all_overlays
2021 to avoid redundant calls to unchain_overlay.
2022 * buffer.c (drop_overlay): New function.
2023 (delete_all_overlays, Fdelete_overlay): Use it.
2024 * minibuf.c (get_minibuffer): Fix comment.
2026 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2028 Port to OpenBSD 5.1 amd64.
2029 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2030 This is needed for OpenBSD, and should be harmless on all BSD systems.
2031 Also, include <sys/sysctl.h>, as it should be available on all
2032 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2033 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2034 use p_pid member, not kp_proc.pid.
2036 2012-07-06 Glenn Morris <rgm@gnu.org>
2038 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2040 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2042 More xmalloc and related cleanup.
2043 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2044 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
2045 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
2046 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
2047 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2048 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2049 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2050 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2051 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2053 Omit needless casts involving void * pointers and allocation.
2054 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2055 as the former is more robust if P's type is changed.
2056 Prefer xzalloc to xmalloc + memset 0.
2057 Simplify malloc-or-realloc to realloc.
2058 Don't worry about xmalloc returning a null pointer.
2059 Prefer xstrdup to xmalloc + strcpy.
2060 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2062 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2063 alloca of a constant.
2065 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2067 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2068 hscroll is larger than the line width. Fixes long and futile
2069 looping inside extend_face_to_end_of_line (on a TTY) producing
2070 glyphs that are not needed and thrown away.
2072 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2074 * marker.c (set_marker_restricted_both): Simplify by using
2077 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2079 * editfns.c (region_limit): Simplify by using clip_to_bounds.
2081 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
2083 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
2084 not defined (Bug#11768).
2085 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2086 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2087 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2088 followed by gtk_box_set_homogeneous (Bug#11768).
2089 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2090 (update_theme_scrollbar_width, xg_create_scroll_bar):
2091 Use gtk_scrollbar_new (Bug#11768).
2092 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2093 (is_box_type): New function (Bug#11768).
2094 (xg_tool_item_stale_p): Call is_box_type.
2095 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2096 with default display (Bug#11768).
2098 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2100 * xdisp.c (window_hscroll_limited): New function.
2101 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2102 coordinates when window's hscroll is set to insanely large
2105 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2107 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2108 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2110 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2113 * lisp.h (xzalloc): New prototype. Omit needless casts.
2114 * alloc.c (xzalloc): New function. Omit needless casts.
2115 * charset.c: Omit needless casts. Convert all calls to
2116 xmalloc with following memset to xzalloc.
2117 * dispnew.c: Likewise.
2118 * fringe.c: Likewise.
2119 * image.c: Likewise.

2166 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2168 * fileio.c (time_error_value): Check the right error number.
2169 Problem reported by Troels Nielsen in
2170 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2172 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2174 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2175 This should be fixed in a better way; see Eli Zaretskii in
2176 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2177 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2179 * fileio.c (time_error_value): Rename from special_mtime.
2180 The old name's problems were noted by Eli Zaretskii in
2181 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2183 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2184 This variable's comment says Emacs needs at least one GDB-visible
2185 symbol of type enum pvec_type, to work around GDB problems.
2186 The symbol's value doesn't matter.
2188 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2189 that causes compilation to fail on pre-C99 compilers.
2191 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2193 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2194 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2196 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2198 * buffer.c (init_buffer_once): Fix initialization of
2199 headers for buffer_defaults and buffer_local_symbols.
2200 Reported by Juanma Barranquero <lekktu@gmail.com>.
2202 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2204 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2205 * lisp.h (enum pvec_type): Use fewer bits.
2206 (PSEUDOVECTOR_SIZE_BITS): New constant.
2207 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2208 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2209 change in pvec_type.
2210 (PSEUDOVECTOR_TYPEP): New macro.
2211 (TYPED_PSEUDOVECTORP): Use it.
2212 * fns.c (internal_equal): Adapt code to extract pvectype.
2213 * emacs.c (gdb_pvec_type): Update type.
2214 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2215 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2216 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2217 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2218 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2219 abusing vector->header.next.nbytes.
2220 (live_vector_p): Use PVEC_TYPE.
2221 (mark_object): Adapt code to extract pvectype. Use switch.
2223 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2225 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2226 Tighten new eassert a bit.
2228 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2230 Fix compilation with --enable-gcc-warnings and -O1
2232 * doprnt.c (doprnt): Change type of tem to int, initialize
2233 to avoid compiler warning. Add eassert.
2234 * search.c (simple_search): Initialize match_byte to avoid
2235 compiler warning. Add eassert.
2237 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2239 Avoid weird behavior with large horizontal scrolls.
2240 Without this change, for example, large hscroll values would
2241 mess up Emacs's display on Fedora 15 x86, presumably due to
2242 overflows in int calculations in the display code.
2243 Also, if buffers had long lines, Emacs would freeze.
2244 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2245 (set_window_hscroll): New function, containing the old guts of
2246 Fset_window_hscroll. Return the clipped value.
2247 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2248 This avoids the need to check against PTRDIFF_MAX.
2250 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2252 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2254 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2256 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2258 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2259 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2260 since GCC 4.4.6 issues a bogus warning for them.
2262 Fix bugs in file timestamp newness comparisons.
2263 * fileio.c (Ffile_newer_than_file_p):
2264 * lread.c (Fload): Use full timestamp resolution of files,
2265 not just the 1-second resolution, so that files that are only
2266 slightly newer still count as newer.
2267 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2268 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2270 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2272 * fileio.c: Improve handling of file time marker. (Bug#11852)
2273 (special_mtime): New function.
2274 (Finsert_file_contents, Fverify_visited_file_modtime):
2275 Use it to set special mtime values consistently.
2277 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2279 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2280 marker for non-existing file. (Bug#11852)
2282 2012-07-03 Glenn Morris <rgm@gnu.org>
2284 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2285 and did not make it into globals.h).
2287 2012-07-03 Tom Tromey <tromey@redhat.com>
2289 * window.c (Fset_window_margins, Fset_window_fringes)

2333 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2334 values which aren't power of 2.
2335 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2336 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2339 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2341 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2343 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2345 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2347 * alloc.c (allocate_vector_block): Remove redundant
2348 calls to mallopt if DOUG_LEA_MALLOC is defined.
2349 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2350 avoid calls to mallopt if zero_vector is returned.
2352 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2354 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2355 is enabled, avoid dereferencing NULL current_sblock if
2358 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2360 Cleanup basic buffer management.
2361 * buffer.h (struct buffer): Change layout to use generic vector
2362 marking code. Fix some comments. Change type of 'clip_changed'
2363 to bitfield. Remove unused #ifndef old.
2364 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2365 (GET_OVERLAYS_AT): Fix indentation.
2366 (for_each_per_buffer_object_at): New macro.
2367 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2370 * alloc.c (allocate_buffer): Adjust to match new layout of
2371 struct buffer. Fix comment.
2372 (mark_overlay): New function.

2374 Lisp area of struct buffer.
2375 (mark_object): Use it. Adjust marking of misc objects
2376 and related comments.
2378 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2380 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2381 wrapper that is not needed because the wrapped code is a no-op (zero
2382 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2383 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2385 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2387 * alloc.c (mark_buffer): Simplify. Remove prototype.
2388 (mark_object): Add comment. Reorganize marking of vector-like
2389 objects. Use CHECK_LIVE for all vector-like objects except buffers
2390 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2391 redundant calls to mark_vectorlike for bool vectors.
2393 2012-06-30 Glenn Morris <rgm@gnu.org>
2395 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2397 * epaths.in (PATH_SITELOADSEARCH): New.
2398 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2399 This is rather than relying on --enable-locallisppath elements
2400 having "site-lisp" in their names. (Bug#10208#25, 11658)
2402 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2404 * w32proc.c (sys_select): Accept and ignore one more argument.
2406 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2408 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2409 (pselect) [!MS_DOS]: Redirect to sys_select.
2411 * sysdep.c: Don't include dos.h and dosfns.h.
2413 * process.c (sys_select):
2414 * msdos.c (sys_select): Accept one more argument and ignore it.
2416 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2417 adapt data types and code to that.
2420 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2421 which clashes with the gnulib function of the same name.
2423 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2425 * font.c (font_style_to_value, font_style_symbolic)
2426 (font_prop_validate_style): Add type checks for values in
2429 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2431 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2434 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2436 * xdisp.c (try_window_id): Undo last change.
2438 * w32.c (getwd): Adjust commentary about startup_dir.
2439 (init_environment): Always call sys_access, even in non-MSVC
2440 builds. Don't chdir to the directory of the Emacs executable.
2441 This undoes code from 1997 which was justified by the need to
2442 "avoid conflicts when removing and renaming directories". But its
2443 downside was that every relative file name was being interpreted
2444 relative to the directory of the Emacs executable, which can never
2445 be TRT. In particular, it broke sys_access when called with
2446 relative file names.
2447 (sys_access): Map GetLastError to errno.
2449 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2451 * window.h (struct window): Change type of 'fringes_outside_margins'

2455 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2458 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

2461 Add QUIT to make the loop interruptible.
2463 2012-06-29 Glenn Morris <rgm@gnu.org>

2467 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2469 * editfns.c (region_limit): Fix type mismatch.
2471 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2473 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2474 undefined. Convert from xassert to eassert.
2475 * nsmenu.m: Convert from xassert to eassert.

2482 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2484 Avoid integer overflow on scroll-left and scroll-right.
2485 * window.c (HSCROLL_MAX): New macro.
2486 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

2491 * window.h (struct window): Change type of 'hscroll',
2492 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2493 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2494 Adjust users accordingly.
2495 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2496 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2497 from EMACS_INT to ptrdiff_t.
2498 (make_window): Omit redundant initialization.

2573 * alloc.c (allocate_string): Omit intervals initialization.
2574 * alloc.c (make_uninit_multibyte_string): Initialize intervals

2633 a better opportunity to optimize away calls to strlen when the
2634 function is called with compile-time constant argument.
2635 * image.c (imagemagick_error): Convert to build_string.
2636 * w32proc.c (sys_spawnve): Likewise.

2639 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2641 Use sprintf return value instead of invoking strlen on result.
2642 In the old days this wasn't portable, since some sprintf
2643 implementations returned char *. But they died out years ago and
2644 Emacs already assumes sprintf returns int.
2645 Similarly for float_to_string.
2646 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2653 * xfns.c (syms_of_xfns):
2654 Use sprintf or float_to_string result to avoid need to call strlen.
2655 * data.c (Fnumber_to_string):
2656 Use make_unibyte_string, since the string must be ASCII.
2657 * lisp.h, print.c (float_to_string): Now returns int length.
2658 * term.c (produce_glyphless_glyph):
2659 Use sprintf result rather than recomputing it.
2661 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

2692 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2694 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2697 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2699 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2700 instead of truncating it to 63 (admittedly a generous limit).
2702 * process.c: Fix spelling and caps in comments.
2704 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

2760 * keyboard.c (kbd_buffer_get_event):

2783 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2784 Privately reported by Herbert J. Skuhra.
2785 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2787 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

2796 language ID in the event parameters.
2798 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2822 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2823 Privately reported by Herbert J. Skuhra.
2824 [__FreeBSD__]: Remove "*/" typo after "#include".
2825 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
2826 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2827 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2828 Don't assume EMACS_TIME and struct timeval are the same type.
2830 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2832 Support higher-resolution time stamps (Bug#9000).
2833 The time stamps are only nanosecond-resolution at the C level,
2834 since that's the best that any real-world system supports now.
2835 But they are picosecond-resolution at the Lisp level, as that's
2836 easy, and leaves room for future OS improvements.
2838 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2841 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2842 Don't get current time unless it's needed.
2844 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2845 now provides it if it's absent.
2846 (start_atimer): Port to higher-res time stamps.
2847 Check for time stamp overflow. Don't get current time more
2848 often than is needed.
2850 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2851 Include systime.h, not time.h.
2852 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2854 * dired.c: Include stat-time.h.
2855 (Ffile-attributes): File times now have higher resolution.

2858 (struct image): Timestamp now has higher resolution.
2860 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2861 has at least microseconds now. All uses removed.
2862 (update_frame, update_single_window, update_window, update_frame_1)
2863 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2865 * editfns.c (time_overflow): Now extern.
2866 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2867 (float-time, Fformat_time_string, Fcurrent_time_string)
2868 (Fcurrent_time_zone): Accept and generate higher-resolution

2871 (decode_time_components, lisp_seconds_argument): New functions.
2872 (make_time): Now static.
2873 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2874 Report an error if the time is invalid, rather than having the caller
2877 * fileio.c: Include <stat-time.h>
2878 (Fcopy_file): Copy higher-resolution time stamps.
2879 Prefer to set the time stamp via a file descriptor if that works.
2880 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2881 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2882 (Fvisited_file_modtime, Fset_visited_file_modtime):
2883 Support higher-resolution time stamps.
2885 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2887 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2889 * image.c (prepare_image_for_display, clear_image_cache)
2890 (lookup_image): Port to higer-resolution time stamps.
2892 * keyboard.c (start_polling, bind_polling_period):
2893 Check for time stamp overflow.
2894 (read_char, kbd_buffer_get_event, timer_start_idle)
2895 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2896 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2897 Port to higher-resolution time stamps. Do not assume time_t is signed.
2898 (decode_timer): New function. Timers are now vectors of length 9,
2899 not 8, to accommodate the picosecond component.
2900 (timer_check_2): Use it.
2902 * nsterm.m (select_timeout, timeval_subtract): Remove.
2903 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2904 as they're a bit more accurate and handle overflow better.
2905 (ns_select): Change prototype to be compatible with pselect.
2906 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2907 * nsterm.h (ns_select): Adjust prototype.
2909 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2910 us-resolution time stamps.
2911 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2913 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2915 * lisp.h (time_overflow): New decl.
2916 (wait_reading_process_output): First arg is now intmax_t, not int,
2917 to accommodate larger waits.
2919 * process.h (struct Lisp_Process.read_output_delay):
2920 Now counts nanoseconds, not microseconds.
2921 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2923 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2924 (wait_reading_process_output):
2925 Port to ns-resolution time stamps.
2926 (Faccept_process_output, wait_reading_process_output):
2927 Check for time stamp overflow. Do not assume time_t is signed.
2928 (select_wrapper): Remove; we now use pselect.
2929 (Fprocess_attributes): Now generates ns-resolution time stamps.
2931 * sysdep.c: Include utimens.h. Don't include utime.h
2932 or worry about struct utimbuf; gnulib does that for us now.
2933 (gettimeofday): Remove; gnulib provides a substitute.
2934 (make_timeval): New function.
2935 (set_file_times): Now sets ns-resolution time stamps.
2936 New arg FD; all uses changed.
2937 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2938 (system_process_attributes):
2939 Now returns ns-resolution time stamp. All uses changed.
2940 Check for time stamp overflow.
2942 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2943 provides a substitute now.
2945 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2946 since it guarantees struct timespec.
2947 (EMACS_TIME): Now struct timespec, so that we can support
2948 ns-resolution time stamps.
2949 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2950 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2951 (EMACS_USECS): Remove.
2952 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2953 so multiply the arg by 1000 before storing it.
2954 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2956 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2957 Port to ns-resolution time stamps.
2958 (EMACS_TIME_NEG_P): Remove; replaced by....
2959 (EMACS_TIME_SIGN): New macro.
2960 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2961 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2962 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2963 (make_timeval, make_lisp_time, decode_time_components): New decls.
2964 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2965 that it mishandled time_t overflow. You can't compare by subtracting!
2966 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2967 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2969 * term.c: Include <sys/time.h>.
2970 (timeval_to_Time): New function, for proper overflow wraparound.
2971 (term_mouse_position, term_mouse_click): Use it.

2975 (Fprimitive_undo): Use them when restoring time stamps.
2977 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2978 (w32_get_internal_run_time):
2979 Port to higher-resolution Emacs time stamps.
2980 (ltime): Now accepts single 64-bit integer, as that's more convenient
2983 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2985 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2986 for compatibility with pselect. Support ns-resolution time stamps.
2988 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2990 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2991 Check for time stamp overflow, and support ns-resolution time stamps.
2993 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2994 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2995 (timeval_subtract): Remove; no longer needed.
2996 (XTflash, XTring_bell, x_wait_for_event):
2997 Port to ns-resolution time stamps. Don't assume time_t is signed.
2999 2012-06-22 Chong Yidong <cyd@gnu.org>

3003 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3005 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3006 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3007 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3008 staticidx goes up to 1597 out of 1600 = 0x640.)
3010 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3012 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3013 Otherwise, the umask might be mistakenly 0 while handling input signals.

3046 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3047 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3048 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3049 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3050 (METER_1, METER_2): Simplify.

3058 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3059 gets killed during executing of this function (Bug#11665).
3060 Try to always return Qt when the buffer has been actually killed.
3061 (Vkill_buffer_query_functions): In doc-string say that functions
3062 run by this hook should not change the current buffer.
3064 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3066 Fix recently-introduced process.c problems found by static checking.

3084 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3086 * lisp.h (eassert): Assume C89 or later.
3087 This removes the need for CHECK.
3088 (CHECK): Remove. Its comments about always evaluating its
3089 argument were confusing, as 'eassert' typically does not evaluate
3092 * coding.c (produce_chars): Use ptrdiff_t, not int.
3094 * xterm.c (x_draw_underwave): Check for integer overflow.
3095 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3264 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
3266 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
3268 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
3269 * alloc.c (make_number) [!defined make_number]:
3270 Remove, as lisp.h always defines this now.
3271 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
3272 (roundup_size): Verify that it is a power of 2.
3273 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
3274 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
3275 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
3276 -DUSE_LSB_TAG=0, to override the automatically-selected default.
3277 USE_LSB_TAG now is always defined to be either 0 or 1.
3279 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3280 code works fine either way, and efficiency is not a concern here,
3281 as the union type is for debugging, not for production.
3282 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3283 Use an inline function on all platforms when using the union type,
3284 since this is simpler and 'static inline' can be used portably
3286 (LISP_INITIALLY_ZERO): New macro.
3287 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3288 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
3290 2012-06-12 Glenn Morris <rgm@gnu.org>

3305 MagickMergeImageLayers is undefined. Use pixel pusher loop if
3306 MagickExportImagePixels is undefined.

3314 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
3315 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
3316 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
3317 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
3319 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
3321 * alloc.c (make_byte_code): New function.

3356 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
3357 dbus_type_is_basic if available.
3358 (xd_extract_signed, xd_extract_unsigned): Rename from
3359 extract_signed and extract_unsigned, respectively. Adapt callers.
3361 2012-06-09 Chong Yidong <cyd@gnu.org>
3363 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).
3365 * fringe.c (Fset_fringe_bitmap_face): Handle the noninteractive
3368 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
3370 * xdisp.c (vmessage): Treat frame message as multibyte.
3371 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
3372 would generate the diagnostic "Making \302\247 buffer-local while
3375 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3377 * dispnew.c (showing_window_margins_p): Undo last change, which

3388 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
3390 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
3391 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3393 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3395 * alloc.c (allocate_vectorlike): Fix last change.
3397 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
3399 Block-based vector allocation of small vectors.
3400 * lisp.h (struct vectorlike_header): New field `nbytes',
3401 adjust comment accordingly.
3402 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
3403 to denote vector blocks. Adjust users (live_vector_p,
3404 mark_maybe_pointer, valid_lisp_object_p) accordingly.
3405 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
3406 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
3407 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
3408 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
3409 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

3424 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
3426 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3428 * doprnt.c (doprnt): Truncate multibyte char correctly.
3429 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3430 would mishandle a string argument "Xc" if X was a multibyte
3431 character of length 2: it would truncate after X's first byte
3432 rather than including all of X.
3434 2012-06-06 Chong Yidong <cyd@gnu.org>
3436 * buffer.c (word_wrap): Doc fix.
3438 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

3483 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3485 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3486 Convert pctcpu and pctmem to Lisp float properly.
3487 Let the compiler fold better, as 100.0/0x8000 is exact.
3489 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3491 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3494 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3496 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3498 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3500 For a 'struct window', replace some Lisp_Object fields to
3501 bitfields where appropriate, remove unused fields.
3502 * window.h (struct window): Remove unused 'last_mark_x' and
3503 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3504 change it's type from Lisp_Object to bitfield.
3505 Change type of 'force_start', 'optional_new_start',
3506 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3507 fields from Lisp_Object to bitfield. Adjust users accordingly.
3509 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3511 Pacify gcc -Wdouble-precision when using Xaw.
3512 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3513 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3514 Use 'float' consistently, rather than 'float' in most places
3515 and 'double' in a couple of places.
3517 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3519 * xdisp.c (handle_stop): Detect whether we have overlay strings
3520 loaded by testing it->current.overlay_string_index to be
3521 non-negative, instead of checking whether n_overlay_strings is
3522 positive. (Bug#11587)
3524 2012-05-31 Chong Yidong <cyd@gnu.org>
3526 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3528 * doc.c (Fsubstitute_command_keys): Doc fix.
3530 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3532 * search.c (search_buffer): Remove calls to
3533 r_alloc_inhibit_buffer_relocation, as it is now called by
3534 maybe_unify_char, which was the cause of relocation of buffer text
3537 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3539 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3540 for the duration of call to load_charset, to avoid problems with
3541 callers of maybe_unify_char that access buffer text through C
3544 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3545 decrement the inhibition flag, instead of just setting or
3548 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3550 Remove obsolete '#define static' cruft.
3551 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3552 This #undef was "temporary" in 2000; it is no longer needed
3553 now that '#define static' has gone away.
3554 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3555 (gray_bitmap_bits): Remove; no longer needed.
3556 All uses replaced with definiens.
3557 * xterm.c: Include "bitmaps/gray.xbm".
3559 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3561 Clean up __executable_start, monstartup when --enable-profiling.
3562 The following changes affect the code only when profiling.
3563 * dispnew.c (__executable_start): Rename from safe_bcopy.
3564 Define only on platforms that need it.
3565 * emacs.c: Include <sys/gmon.h> when profiling.
3566 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3567 (__executable_start): Remove decl, since lisp.h does it now.
3568 (safe_bcopy): Remove decl; no longer has that name.
3569 (main): Coalesce #if into single bit of code, for simplicity.
3570 Cast pointers to uintptr_t, since standard libraries want integers

3574 2012-05-31 Glenn Morris <rgm@gnu.org>
3576 * image.c (Fimagemagick_types): Doc fix.

3594 * lisp.h (Qdefun): Remove.
3595 * lread.c (read1): Tiny simplification.
3597 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3599 Do not create empty overlays with the evaporate property (Bug#9642).
3600 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3601 Bug#9642, but explicitly check that the buffer the overlay would
3602 be moved to is live and rearrange lines to make sure that errors
3603 will not put the overlay in an inconsistent state.
3604 (Fdelete_overlay): Cosmetics.
3606 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3608 * w32term.c (my_bring_window_to_top): New function.
3609 (x_raise_frame): Use handle returned by DeferWindowPos, which
3610 could be different from the original one.
3611 Call my_bring_window_to_top instead of my_set_foreground_window.
3614 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3615 by calling BringWindowToTop.

3620 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3622 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3623 This avoids undefined behavior that might cause the eassert
3624 to not catch an out-of-range value.
3626 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3628 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3638 when referring to sectname field in printf format.
3640 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3642 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3643 Only r_alloc_inhibit_buffer_relocation needed to be added;
3644 the others were already declared.
3646 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3647 before checking whether it's out of range. Put the check inside
3649 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3651 2012-05-27 Ken Brown <kbrown@cornell.edu>
3653 * callproc.c (Fcall_process): Restore a line that was accidentally
3654 commented out in the 2011-02-13 change (bug#11547).

3658 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3659 defined on ralloc.c.
3661 * buffer.c [REL_ALLOC]: Remove prototypes of
3662 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3663 they are now on lisp.h.
3665 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3667 * search.c (search_buffer): Use it to inhibit relocation of buffer
3668 text while re_search_2 is doing its job, because re_search_2 is
3669 passed C pointers to buffer text. (Bug#11519)
3671 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3674 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3675 state after an additional call to move_it_in_display_line_to, keep
3676 the values of it->max_ascent and it->max_descent found for the
3678 (pos_visible_p): Revert the comparison against bottom_y to what it
3679 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3682 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3684 Fix coding-related core dumps with gcc -ftrapv.
3685 The code was computing A - B, where A and B are pointers, and B is
3686 random garbage. This can lead to core dumps on platforms that
3687 have special pointer registers, and it also leads to core dumps on
3688 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3689 A - B only when B is initialized properly.
3690 * coding.c (coding_set_source, coding_set_destination): Return void.
3691 (coding_change_source, coding_change_destinations): New functions,
3692 with the old behaviors of coding_set_source and coding_set_destination.
3693 All callers that need an offset changed to use these new functions.
3695 2012-05-26 Glenn Morris <rgm@gnu.org>
3697 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3699 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3701 Extend mouse support on W32 text-mode console.
3702 * xdisp.c (draw_row_with_mouse_face):
3703 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3705 * w32console.c: Include window.h.
3706 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3708 (initialize_w32_display): Initialize mouse-highlight data.
3710 * w32inevt.c: Include termchar.h and window.h.
3711 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3712 moves, call note_mouse_highlight. If help_echo changed, call
3713 gen_help_event to produce help-echo message in the echo area.
3714 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3717 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3719 * lread.c (read1): Simplify slightly to avoid an overflow warning
3720 with GCC 4.7.0 on x86-64.
3722 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3724 * bidi.c (bidi_mirror_char): Revert last change: an int is
3725 definitely wide enough here.
3727 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3729 Fix integer width and related bugs (Bug#9874).
3730 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3731 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3732 (string_bytes, check_sblock, allocate_string_data):
3733 (compact_small_strings, Fmake_bool_vector, make_string)
3734 (make_unibyte_string, make_multibyte_string)
3735 (make_string_from_bytes, make_specified_string)
3736 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3737 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)

3762 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3763 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3764 (validate_region): Omit unnecessary test for b <= e,
3765 since that's guaranteed by the previous test.

3767 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3768 (report_overlay_modification):

3770 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3779 not int, to avoid needless 32-bit limit on 64-bit hosts.
3780 (exec_byte_code): Use tighter memory-full test, one that checks
3781 for alloca overflow. Don't compute the address of the object just
3782 before an array, as that's not portable. Use EMACS_INT, not
3783 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3784 * callint.c (Fcall_interactively):
3785 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3798 (casify_object): Avoid integer overflow when overallocating buffer.
3799 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3802 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3803 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3806 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3807 For CCL_MapSingle, check that content and value are in int range.

3809 Check that Vcode_version_map_vector is a vector.
3810 (resolve_symbol_ccl_program): Check that vector header is in range.
3811 Always copy the vector, so that we can check its contents reliably
3812 now rather than having to recheck each instruction as it's being
3813 executed. Check that vector words fit in 'int'.
3814 (ccl_get_compiled_code, Fregister_ccl_program)
3815 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3816 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3818 contents are in range.
3819 (Fccl_execute_on_string): Check that status is in range.
3820 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3821 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3822 Accept and return EMACS_INT, not int, because callers can pass values

3829 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3831 avoid mishandling large integers.

3842 Don't rely on undefined behavior with signed left shift overflow.
3843 Don't assume unsigned int fits into fixnum, or that fixnum fits
3844 into unsigned int. Don't require max_code to be a valid fixnum;
3845 that's not true for gb10830 4-byte on a 32-bit host. Allow
3846 invalid_code to be a cons, for the same reason. Require code_offset
3847 to be a character. Avoid int overflow if max_char is close
3849 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3850 this is intended anyway and avoids some undefined behavior.
3851 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3852 INDEX_TO_CODE_POINT, as that's what it expects.
3853 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3854 * charset.h (DECODE_CHAR): Return int, not unsigned;
3855 this is what was intended anyway, and it avoids undefined behavior.
3856 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3857 integer-overflow issues.
3858 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3859 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3860 where the argument is EMACS_INT, and this behavior is not intended.
3861 * chartab.c (Fmake_char_table, Fset_char_table_range)
3862 (uniprop_get_decoder, uniprop_get_encoder):
3863 Don't assume fixnum fits in int.
3864 * cmds.c (move_point): New function, that does the gist of
3865 Fforward_char and Fbackward_char, but does so while checking
3866 for integer overflow more accurately.
3867 (Fforward_char, Fbackward_char): Use it.
3868 (Fforward_line, Fend_of_line, internal_self_insert)
3869 (internal_self_insert):
3870 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4525 (struct scroll_bar): Use struct vectorlike_header
4526 rather than rolling our own approximation.
4527 (SCROLL_BAR_VEC_SIZE): Remove; not used.
4529 2012-05-25 Glenn Morris <rgm@gnu.org>
4531 * lisp.mk (lisp): Update for more files being compiled now.
4533 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
4535 * lread.c: Remove `read_pure' which makes no difference.
4536 (read_pure): Remove var.
4537 (unreadpure): Remove function.
4538 (readevalloop): Don't call read_list with -1 flag.
4539 (read1, read_vector): Don't test read_pure any more.
4540 (read_list): Simplify.

4551 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
4553 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4556 This directory predates autoconf and is no longer needed nowadays.
4557 Move its few remaining bits of functionality to where they're needed.
4558 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

4567 (EMACS_UINT): Define unconditionally now.
4568 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4569 (BITS_PER_EMACS_INT): New constants, replacing
4570 what used to be in config.h, but not useful in #if.
4571 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4572 define them any more.
4573 (VAL_MAX): New macro.
4575 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4576 BITS_PER_EMACS_INT, in #if.
4577 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4578 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4579 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4580 * s/ms-w32.h (DATA_START):
4581 Move here from removed file m/intel386.h.
4582 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4583 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4585 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4587 Assume C89 or later.
4588 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

4595 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4596 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4597 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4598 * xterm.c (input_signal_count): Assume volatile works.
4600 2012-05-21 Ken Brown <kbrown@cornell.edu>
4602 * xgselect.c (xg_select): Fix first argument in call to 'select'
4605 2012-05-20 Ken Brown <kbrown@cornell.edu>
4607 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4608 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4610 2012-05-19 Ken Brown <kbrown@cornell.edu>
4612 * xfns.c (x_in_use): Remove `static' qualifier.
4613 * xterm.h (x_in_use): Declare.
4614 * xgselect.c: Include xterm.h.
4615 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4616 and `display_arg' (bug#9754).
4618 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4620 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4622 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4623 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4625 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4627 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4629 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4630 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4632 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4633 reference to image_cache->refcount.
4634 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4636 2012-05-17 Juri Linkov <juri@jurta.org>
4638 * search.c (Fword_search_regexp, Fword_search_backward)
4639 (Fword_search_forward, Fword_search_backward_lax)
4640 (Fword_search_forward_lax): Move functions to isearch.el
4641 (bug#10145, bug#11381).
4643 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4645 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4647 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4649 * lread.c (init_obarray): Declare Qt and Qnil as special.
4651 2012-05-14 Glenn Morris <rgm@gnu.org>
4653 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4654 Put "libexec" before "bin", for the sake of init_callproc_1.
4656 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4658 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4660 * unexaix.c: Port to more-recent AIX compilers.
4661 (report_error, report_error_1, make_hdr, copy_sym)
4662 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4663 Make arguments const char *, not char *, to avoid violations of C
4664 standard and to fix some AIX warnings reported by Gilles Pion.
4666 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4668 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4669 already have overlays loaded.
4670 (handle_single_display_spec): Before returning without displaying
4671 fringe bitmap, synchronize the bidi iterator with the main display
4672 iterator, by calling iterate_out_of_display_property.
4673 (iterate_out_of_display_property): Detect buffer iteration by
4674 testing that it->string is a Lisp string.
4675 (get_next_display_element): When the current object is exhausted,
4676 and there's something on it->stack, call set_iterator_to_next to
4677 proceed with what's on the stack, instead of returning zero.
4678 (set_iterator_to_next): If called at the end of a Lisp string,
4679 proceed to consider_string_end without incrementing string
4680 position. Don't increment display vector index past the end of
4681 the display vector. (Bug#11417)
4682 (pos_visible_p): Don't report a position visible when move_it_to
4683 stopped at the last line of window, which happens to be scanned
4684 backwards by the bidi iteration. (Bug#11464)
4686 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4688 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4689 and right-margin display specs even if the spec is invalid or we
4690 are on a TTY, and thus unable to display on the fringes.
4691 That's because the text with the property will not be displayed anyway,
4692 so we need to signal to the caller that this is a "replacing"
4693 display spec. This fixes display when the spec is invalid or we
4696 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4698 * unexaix.c (make_hdr): Fix typo in prototype.
4699 This bug broke the build on AIX. Problem reported by Gilles Pion.
4701 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4703 * keyboard.c (kbd_buffer_get_event): Read special events also in
4704 batch mode. (Bug#11415)
4706 2012-05-12 Glenn Morris <rgm@gnu.org>
4708 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4710 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4712 * lisp.mk (lisp): Add newcomment.elc.
4714 2012-05-12 Glenn Morris <rgm@gnu.org>
4716 * Makefile.in (MKDIR_P): New, set by configure.
4717 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4719 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4721 Remove unused function hourglass_started.
4722 * dispextern.h (hourglass_started):
4723 * w32fns.c (hourglass_started):
4724 * xdisp.c (hourglass_started): Remove.
4726 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4728 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4729 Update dependencies.
4731 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4733 * xgselect.c (xg_select): Put maxfds+1 into a var.
4734 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4736 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4738 2012-05-10 Dave Abrahams <dave@boostpro.com>
4740 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4741 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4743 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4745 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4746 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4747 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4748 Initialize xd_registered_buses.
4750 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4752 Untag more efficiently if USE_LSB_TAG.
4753 This is based on a proposal by YAMAMOTO Mitsuharu in
4754 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4755 For an admittedly artificial (nth 8000 longlist) benchmark on
4756 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4757 Emacs's overall text size by 1%.
4758 * lisp.h (XUNTAG): New macro.
4759 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4760 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4761 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4762 * eval.c (Fautoload):
4763 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4764 * frame.h (XFRAME): Use XUNTAG.
4766 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4767 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4768 Remove unportable assumptions about print widths of types like
4770 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4771 intptr_t when converting between pointer and integer, to avoid GCC
4772 warnings about wrong width.
4774 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4776 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4777 stack for each reader_thread, instead of defaulting to 8MB
4778 determined by the linker. This avoids failures in creating
4779 subprocesses on Windows 7, see the discussion in this thread:
4780 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4782 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4784 Fix up display of the *Minibuf-0* buffer in the mini window.
4785 * keyboard.c (read_char): Don't clear the echo area if there's no
4787 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4788 contents of *Minibuf-0*) if there's no message displayed in its stead.
4790 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4792 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4795 2012-05-06 Chong Yidong <cyd@gnu.org>
4797 * lisp.mk (lisp): Update.
4799 2012-05-05 Jim Meyering <meyering@redhat.com>
4801 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4803 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4805 * data.c (PUT_ERROR): New macro.
4806 (syms_of_data): Use it. Add new error type `user-error'.
4807 * undo.c (user_error): New function.
4808 (Fprimitive_undo): Use it.
4809 * print.c (print_error_message): Adjust print style for `user-error'.
4810 * keyboard.c (user_error): New function.
4811 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4813 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4815 Do not limit current-time-string to years 1000..9999.
4816 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4817 (Fcurrent_time_string): Support any year that is supported by the
4818 underlying localtime representation. Don't use asctime, as it
4819 has undefined behavior for years outside the range -999..9999.
4821 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4823 Fix race conditions involving setenv, gmtime, localtime, asctime.
4824 Without this fix, interrupts could mess up code that uses these
4825 nonreentrant functions, since setting TZ invalidates existing
4826 tm_zone or tzname values, and since most of these functions return
4827 pointers to static storage.
4828 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4829 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4830 Grow the critical sections to include not just invoking
4831 localtime/gmtime, but also accessing these functions' results
4832 including their tm_zone values if any, and any related TZ setting.
4833 (format_time_string): Last arg is now struct tm *, not struct tm **,
4834 so that the struct tm is saved in the critical section.
4835 All callers changed. Simplify allocation of initial buffer, partly
4836 motivated by the fact that memory allocation needs to be outside
4837 the critical section.
4839 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4841 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4842 with RESET_INTERVAL.
4844 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4845 Remove duplicated buffer name initialization.
4847 2012-05-02 Jim Meyering <jim@meyering.net>
4849 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4851 * xfns.c (x_window): Use xstrdup (Bug#11375).
4853 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4855 * xdisp.c (pos_visible_p): If already at a newline from the
4856 display string before the 'while' loop, don't walk back the glyphs
4857 from it3.glyph_row. Solves assertion violation when the display
4858 string begins with a newline (egg.el). (Bug#11367)
4860 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4862 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4865 2012-05-01 Glenn Morris <rgm@gnu.org>
4867 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4868 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4869 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4870 All were removed before 23.1.
4872 * dispnew.c: Remove HAVE_LIBNCURSES test;
4873 it is always true on relevant platforms.
4875 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4876 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4878 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

4886 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4888 Do not avoid creating empty evaporating overlays (Bug#9642).
4889 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4890 That is, do not delete an evaporating overlay if it becomes
4891 empty after its bounds are adjusted to fit within its buffer.
4892 This fix caused other problems, and I'm reverting it until we get
4893 to the bottom of them.
4895 2012-04-27 Chong Yidong <cyd@gnu.org>
4897 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4899 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4901 * xdisp.c (pos_visible_p): If the window start position is beyond
4902 ZV, start the display from buffer beginning. Prevents assertion
4903 violation in init_iterator when the minibuffer window is scrolled
4906 * window.c (window_scroll_pixel_based): Likewise.
4908 2012-04-27 Chong Yidong <cyd@gnu.org>

4914 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4915 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)

4922 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4924 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4925 display element, check also the underlying string or buffer
4926 character. (Bug#11341)
4928 * w32menu.c: Include w32heap.h.
4929 (add_menu_item): If the call to AppendMenuW (via
4930 unicode_append_menu) fails, disable Unicode menus only if we are
4931 running on Windows 9X/Me.
4933 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4935 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4938 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4940 * keyboard.c (read_char): Don't wipe echo area for select window
4941 events: These might get delayed via `mouse-autoselect-window'

4946 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4947 manipulation of :loaded-from data.
4949 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4951 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4952 now a cons (bug#11311).
4954 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4956 Do not create empty overlays with the evaporate property (Bug#9642).
4957 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4958 if it becomes empty after its bounds are adjusted to fit within
4959 its buffer. Without this fix, in a nonempty buffer (let ((o
4960 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4961 yields an empty overlay that has the evaporate property, which is
4962 not supposed to happen.
4964 Fix minor GTK3 problems found by static checking.
4965 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

4980 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4982 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4984 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4985 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4986 (__malloc_size_t, __malloc_ptrdiff_t):
4987 Remove. All uses removed, replaced by the definiens if needed,
4988 since we can assume C89 or better now.

4999 Define using prototypes, not old style.
5000 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5001 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

5066 since the two debugging options are incompatible.
5067 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5069 (mem_init, mem_insert, mem_insert_fixup):
5070 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5079 * sysdep.c [__FreeBSD__]: Minor cleanups.
5080 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5081 Use Emacs indenting style more consistently. Avoid some casts.
5082 Use 'double' consistently rather than mixing 'float' and 'double'.
5084 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5086 * sysdep.c (list_system_processes, system_process_attributes):
5087 Add implementation for FreeBSD (Bug#5243).

5102 (print_object): Check for cycles even when print-circle is nil and
5103 print-gensym is t, but only check print_depth if print-circle is nil.
5105 2012-04-20 Chong Yidong <cyd@gnu.org>
5107 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5108 set the status to "failed" and ensure that sentinel is run.

5123 farther than the first row after the header line, if any.
5124 Don't consider the header-line row as "partially visible", even if

5163 New extern decls, to avoid calling undeclared functions.
5164 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5165 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5166 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5167 (NEED_MEM_INSERT): New macro.
5168 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5169 Remove one incorrect comment and fix another.

5181 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5182 [REL_ALLOC]: ... to here, to check interface.
5183 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5184 Remove decls. This fixes an "It stinks!".
5186 * alloc.c (which_symbols): Fix alignment issue / type clash.
5188 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5190 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5207 Remove definition of GC_MARK_STACK, since the default now works.
5208 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5209 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5210 no longer the default.
5211 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5213 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5215 * lread.c (lisp_file_lexically_bound_p):

5236 2012-04-11 Daniel Colascione <dancol@dancol.org>
5238 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5239 against is gone. It's better to use vfork now so that when Cygwin
5240 gains a new, working vfork, we use it automatically (bug#10398).
5242 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5244 * window.c (save_window_save): Obey window-point-insertion-type.

5263 being loaded (bug#10424).
5265 2012-04-09 Glenn Morris <rgm@gnu.org>
5267 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5268 not just in the obarray, before snarfing them. (Bug#11036)

5280 Add convenience `GNUTLS_LOG2i' macro.
5282 * gnutls.c (gnutls_log_function2i): Convenience log function.
5283 (emacs_gnutls_read): Use new log functions,
5284 `gnutls_handshakes_tried' process member, and
5285 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5286 attempts per process (connection).
5288 2012-04-09 Chong Yidong <cyd@gnu.org>

5295 * minibuf.c (Fread_variable): Callers changed.
5297 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5299 * xdisp.c (set_cursor_from_row): If the display string appears in
5300 the buffer at position that is closer to point than the position
5301 after the display string, display the cursor on the first glyph of
5302 the display string. Fixes cursor display when a 'display' text
5303 property immediately follows invisible text. (Bug#11094)
5305 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5307 composite.c: use 'double' consistently
5308 * composite.c (get_composition_id): Use 'double' consistently
5309 instead of converting 'float' to 'double' and vice versa; this is
5310 easier to understand and avoids a GCC warning.
5312 2012-04-09 Glenn Morris <rgm@gnu.org>
5314 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5315 preparation for dumping it with emacs. (Bug#4789)

5337 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5338 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5339 objects, as mark_maybe_pointer will catch them otherwise.
5340 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5341 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5343 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5345 Fix typo that broke non-Windows builds.

5359 [!WINDOWSNT]: New macros.
5360 (init_libxml2_functions, libxml2_loaded_p): New functions.
5361 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5362 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5363 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5364 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5366 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5367 Call init_libxml2_functions before calling libxml2 functions.

5372 xmlCleanupParser directly.
5374 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5376 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5378 * indent.c (Fvertical_motion): If there is a display string at
5379 point, use it.vpos to compute how many lines to backtrack after

5384 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5385 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5386 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5387 macros related to unification of CJK characters. For the details,
5388 see the discussion following the message here:
5389 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5391 2012-04-04 Chong Yidong <cyd@gnu.org>
5393 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5395 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5397 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

5402 * w32menu.c (is_simple_dialog): Properly check lisp types.
5405 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5407 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5408 position we get to after a call to move_it_to fails the
5409 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5410 only if we wind up in a string from display property. (Bug#11063)
5412 * window.c (Fdelete_other_windows_internal): Invalidate the row
5413 and column information about mouse highlight, so that redisplay
5414 restores it after reallocating the glyph matrices. (Bug#7464)
5416 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5417 string comes from a `display' text property, use the buffer
5418 position of that property as if we actually saw that position in
5420 (move_it_by_lines): Remove the assertion that
5421 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5422 violated when there's a before-string at the beginning of a line.
5425 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5427 * xdisp.c (append_space_for_newline): If the default face was
5428 remapped, use the remapped face for the appended newline.
5429 (extend_face_to_end_of_line): Use the remapped default face for
5430 extending the face to the end of the line.
5431 (display_line): Call extend_face_to_end_of_line when the default
5432 face was remapped. (Bug#11068)
5434 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5436 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

5447 2012-03-26 Kenichi Handa <handa@m17n.org>
5449 * dispextern.h (struct glyph): Fix previous change. Change the
5450 bit length of glyphless.ch to 25 (Bug#11082).
5452 2012-03-26 Chong Yidong <cyd@gnu.org>
5454 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5455 (command_loop_1): Use it; inhibit selection update for
5456 handle-select-window too (Bug#8996).
5458 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5460 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5462 2012-03-25 Kenichi Handa <handa@m17n.org>
5464 * dispextern.h (struct glyph): Change the bit length of
5465 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5467 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5469 * s/ms-w32.h (tzname): Include time.h before redirecting to
5470 _tzname. Fixes the MSVC build. (Bug#9960)
5472 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5474 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5477 * xterm.c (XTread_socket): Only modify handling_signal if
5478 !SYNC_INPUT. (Bug#11080)
5480 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5482 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5483 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5484 when fetching a multibyte character consumes more bytes than
5485 CHAR_BYTES returns, due to unification of CJK characters in
5486 string_char. (Bug#11073)
5488 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5490 * process.c (wait_reading_process_output): Handle pty disconnect
5491 by refraining from sending oneself a SIGCHLD (bug#10933).
5493 2012-03-22 Chong Yidong <cyd@gnu.org>

5506 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5508 * w32proc.c (Fw32_set_console_codepage)
5509 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5514 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5515 to reflect default non-nil value of redisplay-dont-pause.
5517 2012-03-19 Kenichi Handa <handa@m17n.org>

5520 it fit in a valid range (Bug#11003).
5522 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5524 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5525 that is not from display property, accept the row as a "cursor
5526 row" if one of the string's character has a non-nil `cursor'
5527 property. Fixes cursor positioning when there are newlines in
5528 overlay strings, e.g. in icomplete.el. (Bug#11035)
5530 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5532 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5534 2012-03-12 Chong Yidong <cyd@gnu.org>
5536 * eval.c (inhibit_lisp_code): Rename from
5537 inhibit_window_configuration_change_hook; move from window.c.
5539 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5540 * window.c (run_window_configuration_change_hook)
5541 (syms_of_window): Callers changed.
5543 2012-03-11 Chong Yidong <cyd@gnu.org>

5556 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5558 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5560 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5561 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5564 2012-03-03 Glenn Morris <rgm@gnu.org>
5566 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5568 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5570 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5571 position past the first glyph_row that ends at ZV. (Bug#10902)
5572 (redisplay_window, next_element_from_string): Fix typos in
5574 (redisplay_window): Pass to move_it_vertically the margin in
5575 pixels, not in screen lines.
5577 2012-03-02 Glenn Morris <rgm@gnu.org>
5579 * buffer.c (buffer-list-update-hook): Doc fix.
5581 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5583 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5584 push_it before setting up the iterator for the first overlay
5585 string, even if we have an empty string loaded.
5586 (next_overlay_string): If there's an empty string on the iterator
5587 stack, pop the stack. (Bug#10903)
5589 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5591 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5592 Suggested by Stefan Monnier in
5593 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5594 * alloc.c (widen_to_Lisp_Object): New static function.
5595 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5596 and widening them to Lisp_Objects. This would work even if
5597 USE_LSB_TAG is defined and wide integers are used, which might
5598 happen in a future version of Emacs.
5600 2012-02-25 Chong Yidong <cyd@gnu.org>
5602 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5605 * xselect.c (Fx_selection_exists_p): Doc fix.
5606 (x_clipboard_manager_save_all): Print an informative message
5607 before saving to clipboard manager.
5609 2012-02-24 Chong Yidong <cyd@gnu.org>
5611 * keyboard.c (process_special_events): Handle all X selection
5612 requests in kbd_buffer, not just the next one (Bug#8869).
5614 2012-02-23 Chong Yidong <cyd@gnu.org>
5616 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5617 call when setting menu-bar-lines and tool-bar-lines parameters.
5618 (unwind_create_frame_1): New helper function.
5620 * window.c (inhibit_window_configuration_change_hook): New var.
5621 (run_window_configuration_change_hook): Obey it.
5622 (syms_of_window): Initialize it.
5624 2012-02-22 Chong Yidong <cyd@gnu.org>
5626 * xterm.c (x_draw_image_relief): Add missing type check for
5627 Vtool_bar_button_margin (Bug#10743).

5631 * fileio.c (Vfile_name_handler_alist): Doc fix.
5633 * buffer.c (Fget_file_buffer): Protect against invalid file
5634 handler return value.
5636 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5638 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5639 when computing $valmask.
5641 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5642 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5643 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5644 It's useless in that case, and it can cause problems on hosts
5645 that allocate halves of EMACS_INT values separately.
5646 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5647 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5648 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5649 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5650 it avoids undefined behavior on hosts where shifting right by more
5651 than the word width has undefined behavior.
5653 2012-02-19 Chong Yidong <cyd@gnu.org>
5655 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5656 (Funhandled_file_name_directory, Ffile_name_as_directory)
5657 (Fdirectory_file_name, Fexpand_file_name)
5658 (Fsubstitute_in_file_name): Protect against invalid file handler
5659 return values (Bug#10845).
5661 2012-02-18 Eli Zaretskii <eliz@gnu.org>

5673 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5675 2012-02-15 Chong Yidong <cyd@gnu.org>
5677 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5678 marked as special. Also, starting docstrings with * is obsolete.
5680 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

5689 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5691 * keymap.c (Fsingle_key_description): Handle char ranges.
5693 2012-02-12 Chong Yidong <cyd@gnu.org>
5695 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5696 as that creates a dangerous corner case.
5698 * window.c (Fdelete_window_internal): Invalidate the mouse
5699 highlight (Bug#9904).
5701 2012-02-12 Glenn Morris <rgm@gnu.org>
5703 * xselect.c (Fx_own_selection_internal)
5704 (Fx_get_selection_internal, Fx_disown_selection_internal)
5705 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5706 * nsselect.m (Fx_own_selection_internal)
5707 (Fx_disown_selection_internal, Fx_selection_exists_p)
5708 (Fx_selection_owner_p, Fx_get_selection_internal):
5709 Sync docs and argument specs with the xselect.c versions.
5711 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5713 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5715 2012-02-11 Eli Zaretskii <eliz@gnu.org>

5718 argument list with xselect.c. (Bug#10783)
5720 * w16select.c (Fx_selection_exists_p): Sync doc string and
5721 argument list with xselect.c. (Bug#10783)

5731 2012-02-07 Chong Yidong <cyd@gnu.org>
5733 * buffer.c (Fbuffer_local_variables)
5734 (buffer_lisp_local_variables): Handle unbound vars correctly;
5735 don't let Qunbound leak into Lisp.
5737 2012-02-07 Glenn Morris <rgm@gnu.org>
5739 * image.c (Fimagemagick_types): Doc fix.
5741 * image.c (imagemagick-render-type): Change it from a lisp object
5742 to an integer. Move the doc here from the lisp manual.

5745 2012-02-06 Chong Yidong <cyd@gnu.org>
5747 * doc.c (store_function_docstring): Avoid applying docstring of
5748 alias to base function (Bug#2603).
5750 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5752 * .gdbinit (pp1, pv1): Remove redundant defines.
5755 2012-02-04 Chong Yidong <cyd@gnu.org>
5757 * nsterm.m: Declare a global (Bug#10694).
5759 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5761 * w32.c (get_emacs_configuration_options):
5762 Include --enable-checking, if specified, in the return value.
5764 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5766 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5767 after rounding frame sizes. (Bug#9723)
5769 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5771 * keyboard.c (adjust_point_for_property): Don't position point
5772 before BEGV. (Bug#10696)
5774 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5776 Handle overflow when computing char display width (Bug#9496).
5777 * character.c (char_width): Return EMACS_INT, not int.
5778 (char_width, c_string_width): Check for overflow when
5779 computing the width; this is possible now that individual
5780 characters can have unbounded width. Problem introduced
5781 by merge from Emacs 23 on 2012-01-19.
5783 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5785 * dbusbind.c (Fdbus_register_method): Mention the return value

5798 2012-02-02 Kenichi Handa <handa@m17n.org>
5800 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5801 0, do not call append_composite_glyph.
5803 2012-02-02 Kenichi Handa <handa@m17n.org>
5805 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5807 (x_produce_glyphs): If the component of a composition is a null
5808 string, set it->pixel_width to 1 to avoid zero-width glyph.
5810 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5812 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5813 first 2 arguments are identical. This makes inserting large

6345 * xdisp.c (redisplay_window): If cursor row is not fully visible
6346 after recentering, and scroll-conservatively is set to a large
6347 number, scroll window by a few more lines to make the cursor fully
6348 visible and out of scroll-margin. (Bug#10105)
6349 (start_display): Don't move to the next line if the display should
6350 start at a newline that is part of a display vector or an overlay

6434 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6435 is set, removing the need for VIRT_ADDRESS_VARIES.
6436 (PURE_P): Use a more-efficient implementation that needs just one
6437 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6438 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6439 to 4 (xorl, subq, cmpq, setbe).
6440 * alloc.c (pure): Always extern now, since that's the
6441 VIRT_ADDR_VARIES behavior.
6442 (PURE_POINTER_P): Use a single comparison, not two, for
6443 consistency with the new puresize.h.
6444 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6451 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6452 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6453 behave as if the cursor position were at the window margin.
6455 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6456 and the cursor position is out of bounds, behave as if the cursor
6457 position were at the window margin. (Bug#10075)
6459 2011-11-18 Chong Yidong <cyd@gnu.org>
6461 * window.c (Fwindow_combination_limit): Make first argument

6483 compute_line_metrics.
6484 (compute_line_metrics): Call row_hash, instead of computing the
6487 * dispnew.c (verify_row_hash): Call row_hash for computing the
6488 hash code of a row, instead of duplicating code from xdisp.c.
6490 * dispextern.h (row_hash): Add prototype.
6492 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

6522 occurrences of window_nest to window_combination_limit.
6524 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6526 * image.c (imagemagick_load_image): Fix typo.
6528 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6530 * xdisp.c (display_line): Move the call to
6531 highlight_trailing_whitespace before the call to
6532 compute_line_metrics, since the latter needs to see the final
6533 faces of all the glyphs to compute ROW's hash value.
6534 Fixes assertion violations in row_equal_p. (Bug#10035)
6536 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6538 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6543 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6544 with user-defined heap size. Bump the default size of the temacs
6545 heap to 27MB, to avoid memory warning when running temacs.
6546 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6548 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6595 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6597 Avoid some portability problems by eschewing 'extern inline' functions.
6598 The trivial performance wins aren't worth the portability hassles; see
6599 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6601 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6603 (window_box_right, window_box_right_offset): Undo previous change,
6604 by removing the "extern"s.
6605 * intervals.c (adjust_intervals_for_insertion)
6606 (adjust_intervals_for_deletion): Undo previous change,
6607 making these static again.
6608 (offset_intervals, temp_set_point_both, temp_set_point)
6609 (copy_intervals_to_string): No longer inline.
6610 * xdisp.c (window_text_bottom_y, window_box_width)

6675 (window_box_width, window_box_left, window_box_left_offset)
6676 (window_box_right, window_box_right_offset): Declare extern.
6677 Otherwise, these inline functions do not conform to C99 and
6678 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6679 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6680 * intervals.c (adjust_intervals_for_insertion)
6681 (adjust_intervals_for_deletion): Now extern, because otherwise the
6682 extern inline functions 'offset_intervals' couldn't refer to it.
6683 (static_offset_intervals): Remove.
6684 (offset_intervals): Rewrite using the old contents of
6685 static_offset_intervals. The old version didn't conform to C99
6686 because an extern inline function contained a reference to an
6687 identifier with static linkage.
6689 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6691 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6709 (Fwindow_vscroll): Doc fix.
6710 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6711 argument, since it makes no sense to pass a live window and for
6712 consistency with window-child.

6740 (unwind_create_frame): New function (Bug#9943).
6741 (Fx_create_frame): Restructure code to be more similar to the one in
6742 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6743 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6744 Move terminal->reference_count++ just before making the frame official
6747 * nsterm.m (x_free_frame_resources): New function.
6748 (x_destroy_window): Move code to x_free_frame_resources.
6750 * xfns.c (unwind_create_frame): Fix comment.

6752 Move terminal->reference_count++ just before making the frame
6753 official. Move initialization of image_cache_refcount and
6754 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

6787 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
6789 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
6791 2011-11-04 Eli Zaretskii <eliz@gnu.org>
6793 * xdisp.c (note_mouse_highlight): If either of
6794 previous/next-single-property-change returns nil, treat that as
6795 the beginning or the end of the buffer. (Bug#9955)
6797 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6799 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
6800 label is not null (Bug#9951).

6811 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
6813 * w32fns.c (unwind_create_frame): If needed, free the glyph
6814 matrices of the partially constructed frame. (Bug#9943)
6815 * xfns.c (unwind_create_frame): Likewise.
6817 2011-11-01 Eli Zaretskii <eliz@gnu.org>
6819 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6820 Don't stop backward scan on the continuation glyph, even though
6821 its CHARPOS is positive.
6822 (mouse_face_from_buffer_pos, note_mouse_highlight):
6823 Rename cover_string to disp_string.
6825 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6827 * window.c (temp_output_buffer_show): Don't use
6828 Vtemp_buffer_show_specifiers.
6829 (Vtemp_buffer_show_specifiers): Remove unused variable.
6831 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6833 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6834 past the beginning of the current glyph matrix.
6836 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
6838 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
6839 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6840 HAVE_GTK3 (Bug#9869).
6842 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6843 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6845 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6847 * xterm.c: Declare x_handle_net_wm_state to return int.
6848 (handle_one_xevent): Check if we are iconified but don't have
6849 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6850 (get_current_wm_state): Return non-zero if not hidden,
6851 check for _NET_WM_STATE_HIDDEN (Bug#9893).

6856 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6858 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6859 so that this new function doesn't get optimized away by a
6860 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6862 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6864 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6866 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6868 Fix the `xbytecode' command.
6869 * .gdbinit (xprintbytestr): New command.
6870 (xwhichsymbols): Rename from `which'; all callers changed.
6871 (xbytecode): Print the byte-code string as well.
6873 2011-10-29 Kim Storm <storm@cua.dk>
6875 * alloc.c (which_symbols): New function.
6877 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6879 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6882 2011-10-29 Glenn Morris <rgm@gnu.org>
6884 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6885 Not clear what it was for, and it causes various bugs. (Bug#9839)
6887 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6889 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6890 possible random value that matches one of those tested as
6891 condition to clear the mouse face.
6893 2011-10-28 Chong Yidong <cyd@gnu.org>
6895 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6897 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6899 * window.c (make_window): Initialize phys_cursor_on_p.
6901 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6903 * lisp.h (struct Lisp_Symbol): Update comments.
6905 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6907 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6909 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6911 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6912 <oslsachem@gmail.com> for helping to debug this.
6914 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6915 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6916 (g_b_init_get_glyph_outline_w): New static variables.
6917 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6918 (GetGlyphOutlineW_Proc): New typedefs.
6919 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6920 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6922 (w32font_open_internal, compute_metrics):
6923 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6924 instead of calling the "wide" APIs directly.
6926 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6928 * w32.h (syms_of_w32font): Add prototype.
6930 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6932 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6933 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6934 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6935 (Fmove_to_window_line): Doc fix.
6937 2011-10-27 Chong Yidong <cyd@gnu.org>
6939 * process.c (make_process): Set gnutls_state to NULL.
6941 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6942 non-NULL, regardless of GNUTLS_INITSTAGE.
6943 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6944 an error. Set process slots as soon as we allocate them.
6946 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6948 2011-10-27 Chong Yidong <cyd@gnu.org>

6954 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6955 (deactivate_process): Call emacs_gnutls_deinit.
6957 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6961 * w32font.c (fill_in_logfont):
6962 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6964 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6966 * w32fns.c (w32_default_color_map): New function,
6967 extracted from Fw32_default_color_map.
6968 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6970 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6972 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6974 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6976 * keyboard.c (test_undefined): New function (bug#9751).
6977 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6979 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6981 * sysdep.c (init_sys_modes): Fix the check for the controlling
6982 terminal (Bug#6649).
6984 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6986 * dispextern.h (struct bidi_it): New member next_en_type.
6988 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6989 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6990 current character, check also for next_en_type being WEAK_EN.
6991 (bidi_resolve_weak): Don't enter the expensive loop if the current
6992 position is before next_en_pos. Record the bidi type of the first
6993 non-ET, non-BN character we find, in addition to its position.
6994 (bidi_level_of_next_char): Invalidate next_en_type when
6995 next_en_pos is over-stepped.
6997 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6999 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7000 * editfns.c: Rewrite current-time-zone so that it invokes
7001 the equivalent of (format-time-string "%Z") to get the time zone name.
7002 This fixes a bug when the time zone name contains characters that
7003 need converting from the system time locale to Emacs internal format.
7004 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7005 that patch fixed format-time-string to do the conversion, but
7006 I forgot to fix current-time-zone.
7007 (format_time_string): New function, containing most of
7008 what Fformat_time_string used to contain.
7009 (Fformat_time_string): Rewrite in terms of format_time_string.
7010 This doesn't change this function's behavior.
7011 (current-time-zone): Rewrite to use format_time_string.
7012 This fixes the bug reported by Michael Schierl in
7013 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7014 Jason Rumney's 2007-06-07 change worked around this bug, but
7016 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7018 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7020 * xdisp.c (start_display): If the character at POS is displayed
7021 via a display vector, reset IT->current.dpvec_index to zero.
7022 (try_window_reusing_current_matrix): If a line ends in a display
7023 vector or the next line starts in a display vector, continue
7024 redrawing the window even though the character position of
7025 start_row was reached.
7028 2011-10-18 Chong Yidong <cyd@gnu.org>
7030 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7031 with nobreak-char-display too.
7033 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7035 Fix part 3 of bug#9771.
7036 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7037 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7038 non-neutral characters if the current character is a paragraph
7039 separator (a.k.a. Newline). This avoids running the same
7040 expensive loop twice, once when we consume the preceding newline
7041 and the other time when the line actually needs to be displayed.
7042 Avoid the loop when we see neutrals on the base embedding level
7043 following a character whose directionality is the same as the
7044 paragraph's. This avoids running the expensive loop when a line
7045 ends in a long sequence of neutrals, like control characters.
7046 Add assertion against STRONG_AL type. Slightly rearrange code
7047 that determines the type of a neutral given the first non-neutral
7049 (bidi_level_of_next_char): Set next_en_pos to zero when
7050 invalidating its info.
7052 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7054 * xdisp.c (push_display_prop): Determine whether to record string
7055 or buffer position by IT->string, not by IT->method. Allow
7056 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7057 (move_it_vertically_backward): Don't look for character position
7058 immediately after the newline when in a continuation line.
7061 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7063 * window.c (coordinates_in_window): Rewrite and delabelize
7064 vertical border check. (Bug#5357) (Bug#9618)
7066 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7068 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7069 errors in XSetWindowBorder (bug#9310).
7071 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7073 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7074 avoid crash when xmalloc overrun checking is enabled.
7076 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7078 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7079 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7080 cursor motion with <left> and <right> arrow keys.
7082 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7083 some callers set that themselves.
7085 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7087 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7088 display string and the previous row comes from the same string and
7089 is empty. (Bug#9739) (Bug#9738)
7091 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7093 * doc.c (get_doc_string): Encode file name (bug#9735).
7095 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7097 * bidi.c (bidi_level_of_next_char):
7098 * xdisp.c (get_visually_first_element): Remove old incorrect
7099 comments regarding the Unicode Line Separator character.
7101 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7103 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7105 * alloc.c (Fgc_status): Do not access beyond zombies array
7106 boundary if nzombies > MAX_ZOMBIES.
7107 * alloc.c (dump_zombies): Add missing format specifier.
7109 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7111 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7112 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7114 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7115 Some packages use them to denote characters with modifiers.
7117 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7119 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7120 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7121 matching a pp-number. Rename parameter var to var1.
7123 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7125 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7127 2011-10-08 Glenn Morris <rgm@gnu.org>
7129 * callint.c (Fcall_interactively): Give a more explicit error for the
7130 'c' case with a non-character input. (Bug#8479)
7132 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7134 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7136 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7137 lines that are hscrolled on the left.
7139 * dispnew.c (buffer_posn_from_coords): Account for a possible
7140 presence of header-line. (Bug#4426)
7142 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7144 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7145 Don't advertise functionality which we discourage or doesn't work.
7147 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7149 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7150 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7151 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7152 this makes Emacs dump core during garbage collection on rare
7153 occasions. sizeof is obviously inferior to offsetof here, so
7154 stick with offsetof.
7155 (GC_POINTER_ALIGNMENT): New macro.
7156 (mark_memory): Omit 3rd (offset) arg; caller changed.
7157 Don't assume EMACS_INT alignment is the same as pointer alignment.
7159 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7161 * keyboard.c (read_key_sequence_remapped): New var.
7162 (read_key_sequence): Compute remapping in the right buffer.
7163 (command_loop_1): Use read_key_sequence's remapping directly.
7165 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7167 * dired.c (file_name_completion): Don't expand file name.
7168 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7169 before checking file name handler.
7171 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7172 they've been requested explicitly (bug#9591).
7174 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7176 * keymap.c (Fsingle_key_description): Use make_specified_string
7177 instead of build_string to build string from push_key_description.
7180 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7182 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7183 This fixes a Y2038 bug on 64-bit hosts.
7184 * buffer.c (reset_buffer):
7185 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7186 (Fclear_buffer_auto_save_failure):
7187 Use 0, not -1, to represent an unset failure time, since time_t
7188 might not be signed.
7190 Remove dependency on glibc malloc internals.
7191 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7192 Move back here from lisp.h, but with their new implementations.
7193 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7194 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7195 * charset.c (charset_table_init): New static var.
7196 (syms_of_charset): Use it instead of xmalloc. This removes a
7197 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7198 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7199 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7200 Move back to alloc.c.
7201 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7202 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7204 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7206 * nsterm.m (windowDidResize): Call x_set_window_size only when
7207 ns_in_resize is true. Otherwise set pixelwidth/height and
7208 call change_frame_size (Bug#9628).
7210 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7212 Port --enable-checking=all to Fedora 14 x86-64.
7213 * charset.c (syms_of_charset): Also account for glibc malloc's
7214 internal overhead when calculating the initial malloc maximum.
7216 Port --enable-checking=all to Fedora 14 x86.
7217 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7219 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7220 (overrun_check_realloc, overrun_check_free):
7221 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7222 That way, xmalloc returns a properly-aligned pointer even if
7223 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7224 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7225 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7226 into account when calculating the initial malloc maximum.
7227 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7228 Move here from alloc.c, so that charset.c can use it too.
7229 Properly align; the old code wasn't right for common 32-bit hosts
7230 when configured with --enable-checking=all.
7231 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7232 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7234 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7236 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7239 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7241 * xdisp.c (compute_display_string_end): If there's no display
7242 string at CHARPOS, return -1.
7244 * bidi.c (bidi_fetch_char): When compute_display_string_end
7245 returns a negative value, treat the character as a normal
7246 character not covered by a display string. (Bug#9624)

7250 * lread.c (Fread_from_string): Fix typo in docstring.
7252 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7254 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7255 newline, reseat the iterator instead of bidi-iterating there one
7256 character at a time. (Bug#9610)
7257 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7258 TO_CHARPOS if the bidi iterator is at base embedding level.
7260 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7262 * lread.c (readevalloop): Use correct code for NBSP.
7263 (read1): Likewise. (Bug#9608)
7265 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7267 * dbusbind.c (Fdbus_register_signal): When service is not
7268 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7270 2011-09-25 Glenn Morris <rgm@gnu.org>
7272 * buffer.c (truncate-lines): Doc fix.
7274 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

7289 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7291 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7292 Default value is now t. Doc fix.
7294 * indent.c (Fvertical_motion): Compute and apply the overshoot
7295 logic when moving up, not only when moving down. Fix the
7296 confusing name and values of the it_overshoot_expected variable;
7297 logic changes accordingly. (Bug#9254) (Bug#9549)
7299 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7300 CHARPOS is covered by a display string which includes newlines.
7301 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7302 is covered by a display string with embedded newlines.
7304 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7306 * dbusbind.c (Fdbus_register_signal): Add match rule to
7307 Vdbus_registered_objects_table. (Bug#9581)
7308 (Fdbus_register_method, Vdbus_registered_objects_table):
7311 2011-09-24 Jim Meyering <meyering@redhat.com>
7313 do not ignore write error for any output size
7314 The previous change was incomplete.
7315 While it makes emacs --batch detect the vast majority of stdout
7316 write failures, errors were still ignored whenever the output size is
7317 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7318 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7319 && echo FAIL: ignored write error
7320 FAIL: ignored write error
7321 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7322 && echo FAIL: ignored write error
7323 FAIL: ignored write error
7324 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7326 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7328 * emacs.c (Fkill_emacs): In noninteractive mode exit
7329 non-successfully if a write error occurred on stdout. (Bug#9574)
7331 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7333 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7336 * dispextern.h (struct it): Update the comment documenting what
7339 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7341 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7342 a display string, extend search for cursor position to end of row.
7343 (find_row_edges): If the row ends in a newline from a display
7344 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7345 Handle the case of a display string with multiple newlines.
7346 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7347 non-empty line. Fixes confusing cursor motion with arrow keys at
7348 the beginning of a line that starts with whitespace.
7350 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7352 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7355 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7357 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7360 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7362 * xdisp.c (display_line): Record maximum and minimum buffer
7363 positions even if no glyphs were produced (e.g., by a zero-width
7364 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7365 buffer positions that will be removed from the glyph row because
7367 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7368 column is beyond frame width: don't subtract 1 "pixel" when
7369 computing width of the stretch.
7370 (reseat_at_next_visible_line_start): Undo the change made on
7371 2011-09-17 that saved paragraph information and restored it after
7372 the call to `reseat'. (Bug#9545)
7374 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7376 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7377 and turn window cursor on if cleared (Bug#9415).

7381 * search.c (boyer_moore): Take unibyte characters from pattern
7382 literally. (Bug#9458)
7384 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7386 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7388 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7390 Fix minor problem found by static checking.
7391 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7392 initialized, to pacify gcc -Wuninitialized.
7394 * fileio.c: Report proper errno when syscall falls.
7395 (Finsert_file_contents): Save and restore errno,
7396 so that report_file_error outputs the correct diagnostic.
7397 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7399 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7401 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7403 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7405 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7406 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7408 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7410 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7411 about the current paragraph and restore it after the call to reseat.
7413 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7414 (bidi_find_paragraph_start): Search back for paragraph beginning
7415 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7416 (bidi_move_to_visually_next): Only trigger paragraph-related
7417 computations when the last character is a newline or at EOB, not
7418 just any NEUTRAL_B. (Bug#9470)
7420 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7421 truncated lines if point is covered by a display string. (Bug#9524)
7423 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7425 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7426 (cons_to_x_long): New function.
7427 (lisp_data_to_selection_data): Use it. Correct the test for
7428 short-versus-long data; it was negated. Break out of vector
7429 loop, for efficiency, when a long datum is discovered.
7431 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7433 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7435 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7437 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7438 GCC PR/17406) by declaring this function with external scope.
7440 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7442 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7443 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7445 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7447 * editfns.c (Fformat): Correctly handle text properties on "%%".

7451 * xterm.c (x_draw_composite_glyph_string_foreground):
7452 * w32term.c (x_draw_composite_glyph_string_foreground):
7453 * term.c (encode_terminal_code):
7454 * composite.c (composition_update_it, get_composition_id):
7455 * xdisp.c (get_next_display_element)

7457 of TAB characters in a composition.
7459 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7461 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7462 This occurs when processing a multibyte format.
7463 Problem reported by Wolfgang Jenker.
7465 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7467 * xdisp.c (try_cursor_movement): Only check for exact match if
7468 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7470 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7472 Remove unused external symbols.
7473 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7474 * xdisp.c (calc_pixel_width_or_height): Now static.
7475 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7476 * indent.c (check_display_width):
7477 * w32term.c: Fix comment to match code.
7478 * xterm.c, xterm.h (x_catching_errors): Remove.
7480 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7482 * xselect.c: Use signed conversions more consistently (Bug#9498).
7483 (selection_data_to_lisp_data): Assume incoming selection data are
7484 signed integers, not unsigned. This is to be consistent with
7485 outgoing selection data, which was modified to use signed integers
7486 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7487 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7488 expects long, not unsigned long.
7490 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7492 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7493 computation of loop end. Reported by Johan Bockgård
7496 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7498 * frame.c (Fother_visible_frames_p): Function deleted.
7500 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7502 * indent.c (compute_motion): Process display vector front to back
7503 rather than the other way around. (Bug#2496)
7505 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7507 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7509 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7511 * minibuf.c (Fread_from_minibuffer): Doc fix.
7513 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7515 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7516 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7518 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7520 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7521 value for non-existent files.
7523 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7525 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7526 set its "size" to -1. This will set the modtime_size field of
7527 the corresponding buffer to -1, which is what
7528 verify-visited-file-modtime expects for files that do not exist.
7531 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7533 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7535 * lisp.h: ... from here. push_key_description is no longer
7536 defined in keyboard.c, so its declaration should not be in
7537 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7538 logically belongs with push_key_description.
7540 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7542 * buffer.h: Include <sys/types.h> instead of <time.h>.
7543 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7544 Problem reported by Herbert J. Skuhra.
7546 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7548 * xml.c (parse_region): Make the parsing work for
7549 non-comment-starting XML files again (bug#9144).
7551 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7553 * image.c (gif_load): Fix calculation of bottom and right corner.
7556 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7558 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7559 redisplay in small windows.
7561 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7563 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7565 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7567 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7568 Operate on live windows only.
7570 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7572 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7574 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7576 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7577 only under bidi iteration.
7579 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7581 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7583 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7585 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7586 Without this fix, the command to link temacs failed due to an
7587 undefined symbol __builtin_isnan. This is because
7588 /usr/include/iso/math_c99.h #defines isnan(x) to
7589 __builtin_isnan(x), but the bundled gcc, which identifies itself
7590 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7592 * floatfns.c (isnan): #undef, and then #define to a clone of
7594 (Fisnan): Always define, since it's always available now.
7595 (syms_of_floatfns): Always define isnan at the Lisp level.
7597 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7599 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7601 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7603 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7604 The previous code assumed that file offsets (off_t values) fit in
7605 EMACS_INT variables, which is not true on typical 32-bit hosts.
7606 The code messed up by falsely reporting buffer overflow in cases
7607 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7608 when "big" contains more than 2**29 bytes, even though this
7609 inserts just one byte and does not overflow the buffer.
7610 (Finsert_file_contents): Store file offsets as off_t
7611 values, not as EMACS_INT values. Check for overflow when
7612 converting between EMACS_INT and off_t. When checking for
7613 buffer overflow or for overlap, take the offsets into account.
7614 Don't use EMACS_INT for small values where int suffices.
7615 When checking for overlap, fix a typo: ZV was used where
7616 ZV_BYTE was intended.
7617 (Fwrite_region): Don't assume off_t fits into 'long'.
7618 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7620 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7622 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7624 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7626 sprintf-related integer and memory overflow issues (Bug#9412).
7628 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7629 (esprintf, exprintf, evxprintf): New functions.
7630 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7631 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7632 (modify_event_symbol): Do not assume that the length of
7633 name_alist_or_stem is safe to alloca and fits in int.
7634 (Fexecute_extended_command): Likewise for function name and binding.
7635 (Frecursion_depth): Wrap around reliably on integer overflow.
7636 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7637 since some callers pass EMACS_INT values.
7638 (Fsingle_key_description): Don't crash if symbol name contains more
7639 than MAX_ALLOCA bytes.
7640 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7641 (get_minibuffer): Arg is now EMACS_INT, not int.
7642 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7643 (esprintf, exprintf, evxprintf): New decls.
7644 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7646 * dbusbind.c (signature_cat): New function.
7647 (xd_signature, Fdbus_register_signal):
7648 Do not overrun buffer; instead, report string overflow.
7650 * dispnew.c (add_window_display_history): Don't overrun buffer.
7651 Truncate instead; this is OK since it's just a log.
7653 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7654 even if the time zone offset is outlandishly large.
7655 Don't mishandle offset == INT_MIN.
7657 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7658 when creating daemon; the previous buffer-overflow check was incorrect.
7660 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7661 which has the guts of the old verror function.
7663 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7664 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7666 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7667 (font_unparse_xlfd): Don't blindly alloca long strings.
7668 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7669 fits in int, when using sprintf. Use single snprintf to count
7670 length of string rather than counting it via multiple sprintfs;
7671 that's simpler and more reliable.
7672 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7673 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7674 sprintf, in case result does not fit in int.
7676 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7677 (fontset_from_font): Print it.
7679 * frame.c (tty_frame_count): Now printmax_t, not int.
7680 (make_terminal_frame, set_term_frame_name): Print it.
7681 (x_report_frame_params): In X, window IDs are unsigned long,
7682 not signed long, so print them as unsigned.
7683 (validate_x_resource_name): Check for implausibly long names,
7684 and don't assume name length fits in 'int'.
7685 (x_get_resource_string): Don't blindly alloca invocation name;
7686 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7689 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7690 (xg_check_special_colors, xg_set_geometry):
7691 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7693 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7694 Use esprintf, not sprintf, in case result does not fit in int.
7696 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7697 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7698 it as a large positive number.
7699 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7700 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7702 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7703 in case result does not fit in int.
7705 * print.c (float_to_string): Detect width overflow more reliably.
7706 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7707 buffer overrun. Don't assume list length fits in 'int'. Treat
7708 print length of 0 as 0, not as infinity; to be consistent with other
7709 uses of print length in this function. Don't overflow print length
7710 index. Don't assume hash table size fits in 'long', or that
7711 vectorlike size fits in 'unsigned long'.
7713 * process.c (make_process): Use printmax_t, not int, to format
7714 process-name gensyms.
7716 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7718 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7719 to avoid potential buffer overrun.
7721 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7722 if X resource line is longer than 512 bytes.
7724 * xfns.c (x_window): Make sprintf buffer a bit bigger
7725 to avoid potential buffer overrun.
7727 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7729 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7731 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7733 Integer overflow fixes for scrolling, etc.
7734 Without these, Emacs silently mishandles large integers sometimes.
7735 For example, "C-u 4294967297 M-x recenter" was treated as if
7736 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7738 * xdisp.c (try_window_id): Check Emacs fixnum range before
7739 converting to 'int'.
7741 * window.c (window_scroll_line_based, Frecenter):
7742 Check that an Emacs fixnum is in range before assigning it to 'int'.
7743 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7744 values converted from Emacs fixnums.
7745 (Frecenter): Don't wrap around a line count if it is out of 'int'
7746 range; instead, treat it as an extreme value.
7747 (Fset_window_configuration, compare_window_configurations):
7748 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7750 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7751 that can exceed INT_MAX. Check that EMACS_INT value is in range
7752 before assigning it to the (possibly-narrower) index.
7753 (match_limit): Don't assume that a fixnum can fit in 'int'.
7755 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7758 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7759 (Fvertical_motion): Don't wrap around LINES values that don't fit
7760 in 'int'. Instead, treat them as extreme values. This is good
7761 enough for windows, which can't have more than INT_MAX lines anyway.
7763 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7765 * Require libxml/parser.h to avoid compilation warning.
7767 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7769 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7770 since this reportedly can destroy thread storage.
7772 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7774 * syntax.c (find_defun_start): Update all cache variables if
7775 exiting early (Bug#9401).
7777 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7779 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7781 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7782 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7783 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7785 * term.c (tty_append_glyph): New function.
7786 (produce_stretch_glyph): Static function and its prototype deleted.
7788 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7791 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7793 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7794 when checking :margin (Bug#9390).
7795 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7796 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7797 so that the name doesn't mislead. All uses changed.
7799 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7801 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7804 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7806 * xdisp.c (move_it_to): Don't bail out early when reaching
7807 position beyond to_charpos, if we are scanning backwards.
7808 (move_it_vertically_backward): When DY == 0, make sure we get to
7809 the first character in the line after the newline.
7811 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7813 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7814 (ccl_driver): Do not generate an out-of-range pointer.
7815 (Fccl_execute_on_string): Remove unnecessary check for
7816 integer overflow, noted by Stefan Monnier in
7817 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7818 Remove a FIXME that didn't need fixing.
7819 Simplify the newly-introduced buffer reallocation code.
7821 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7823 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7825 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7827 Integer and memory overflow issues (Bug#9196).
7829 * doc.c (get_doc_string): Rework so that
7830 get_doc_string_buffer_size is the actual buffer size, rather than
7831 being 1 less than the actual buffer size; this makes xpalloc more
7834 * image.c (x_allocate_bitmap_record, cache_image):
7835 * xselect.c (Fx_register_dnd_atom):
7836 Simplify previous changes by using xpalloc.
7838 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7839 since either will do and ptrdiff_t is convenient with xpalloc.
7841 * charset.c (charset_table_size)
7842 (struct charset_sort_data.priority): Now ptrdiff_t.
7843 (charset_compare): Don't overflow if priorities differ greatly.
7844 (Fsort_charsets): Don't assume list length fits in int.
7845 Check for size-calculation overflow when allocating sort data.
7846 (syms_of_charset): Allocate an initial charset table that is
7847 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7849 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7851 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7852 The actual value is always <= INT_MAX, and leaving it unsigned made
7853 overflow checking harder.
7855 * dispextern.h (struct glyph_matrix.rows_allocated)
7856 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7857 with xpalloc. The values are still always <= INT_MAX.
7859 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7861 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7862 (SAFE_NALLOCA): New macro.
7864 * region-cache.c (struct boundary.pos, find_cache_boundary)
7865 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7866 (set_cache_region, invalidate_region_cache)
7867 (revalidate_region_cache, know_region_cache, region_cache_forward)
7868 (region_cache_backward, pp_cache):
7869 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7870 so that ptrdiff_t * can be passed to xpalloc.
7871 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7872 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7873 (pp_cache): Don't assume cache_len fits in int.
7874 * region-cache.h: Adjust extern decls to match.
7876 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7877 EMACS_INT, since either will do, for xpalloc.
7879 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7880 (xnmalloc, xnrealloc, xpalloc): New functions.
7882 * bidi.c (bidi_shelve_header_size): New constant.
7883 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7884 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7886 * bidi.c (bidi_cache_shrink):
7887 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7889 Don't update size of array until after memory allocation succeeds,
7890 because xmalloc/xrealloc may not return.
7891 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7892 now that we have proper integer overflow checking.
7893 (record_overlay_string, overlay_strings): Catch overflows when
7894 calculating size of overlay_str_buf.
7896 * callproc.c (Fcall_process): Check for size overflow when
7897 calculating size of args2.
7898 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7899 Normally we prefer signed values, but sticking with ptrdiff_t would
7900 require adding more-complicated checks.
7902 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7903 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7904 Redo buffer-overflow calculations to avoid integer overflow.
7905 Add a FIXME comment where memory seems to be over-allocated.
7907 * character.c (Fstring): Check for size-calculation overflow.
7909 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7910 unnecessary integer overflow. Check for size overflow.
7911 (encode_coding_object): Don't update size until xmalloc succeeds.
7913 * composite.c (get_composition_id): Check for overflow in glyph
7914 length calculations.
7916 Integer and memory overflow fixes for display code.
7917 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7918 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7919 (scrolling_window): Check for overflow in size calculations.
7920 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7931 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7932 (get_doc_string): Check for size calculation overflow.
7933 Don't update size until allocation succeeds.
7934 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7935 EMACS_INT, where ptrdiff_t will do.
7936 (Fsubstitute_command_keys): Check for string overflow.
7938 * editfns.c (set_time_zone_rule): Don't assume environment length
7940 (message_length): Now ptrdiff_t, not int.
7941 (Fmessage_box): Don't update size until allocation succeeds.
7942 Don't assume message length fits in int.
7943 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7945 * emacs.c (main): Do not reallocate argv, since there is a null at
7946 the end that can be overwritten, and this way there's no need to
7947 worry about size-calculation overflow.
7948 (sort_args): Check for size-calculation overflow.
7950 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7952 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7954 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7955 (x_set_scroll_bar_width, x_figure_window_size):
7956 Check for integer overflow.
7957 (x_set_alpha): Do not assume XINT fits in int.
7959 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7960 This is for the members text_lines, text_cols, total_lines, total_cols,
7961 where the system imposes an 'int' limit.
7963 * fringe.c (Fdefine_fringe_bitmap):
7964 Don't update size until alloc works.
7966 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7967 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7969 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7970 Check for size-calculation overflow.
7971 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7972 do, as we prefer signed integers.
7973 (id_to_widget.max_size, id_to_widget.used)
7974 (xg_store_widget_in_map, xg_remove_widget_from_map)
7975 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7976 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7977 Use and return ptrdiff_t, not int.
7978 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7979 * gtkutil.h: Change prototypes to match the above.
7981 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7982 are duplicate now that they've been promoted to lisp.h.
7983 (x_allocate_bitmap_record, x_alloc_image_color)
7984 (make_image_cache, cache_image, xpm_load):
7985 Don't update size until alloc is done.

7995 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7996 Use ptrdiff_t, not int, to count maps.
7997 (read_char_minibuf_menu_prompt): Check for overflow in size
7998 calculations. Don't update size until allocation succeeds.

8009 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
8010 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8012 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8013 Now ptrdiff_t, not int.
8014 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

8025 * search.c (Freplace_match): Check for size calculation overflow.
8026 (Fset_match_data): Don't assume list lengths fit in 'int'.
8028 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8029 for command line length. Do not attempt to address one before the
8030 beginning of an array, as that's not portable.

8033 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8035 (encode_terminal_code, calculate_costs): Check for size
8036 calculation overflow.
8037 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
8038 table lengths and related sizes. Don't update size until alloc
8039 done. Redo calculations to avoid overflow.
8040 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8042 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

8059 (Finternal_make_lisp_face, cache_face):
8060 Check for size calculation overflow.
8061 (cache_face): Treat size calculation overflows as if they were
8062 memory exhaustion (the usual treatment), rather than aborting.
8064 * xfns.c (x_encode_text, x_set_name_internal)
8065 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8066 sizes, since they can exceed INT_MAX in size. Check for size

8070 (xg_select): Check for size calculation overflow.
8071 Don't update size until alloc done.
8073 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8074 as sprintf is limited to int lengths.
8076 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8077 (X_LONG_MIN): New macros.
8078 Use them to make the following changes clearer.
8079 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8080 This change doesn't affect the value now, but it may help remind
8081 future maintainers not to raise the value too much later.
8082 (SELECTION_QUANTUM): Remove, replacing with ...
8083 (selection_quantum): ... new function, which avoids overflow.
8085 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8086 assumption that selection length fits in 'int'.

8089 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8090 (lisp_data_to_selection_data, clean_local_selection_data):

8094 Redo calculations to avoid overflow.
8095 (x_reply_selection_request): When sending hint, ceiling it at
8096 X_LONG_MAX rather than relying on wraparound overflow to send

8099 (lisp_data_to_selection_data, x_property_data_to_lisp):
8100 Check for size-calculation overflow.

8103 Don't store size until memory allocation succeeds.
8104 (x_get_window_property): Plug memory leak on memory exhaustion.
8105 Don't double-block input; malloc is safe here. Don't assume 2**34
8106 - 4 fits in unsigned long. Add an xassert to check
8107 XGetWindowProperty overflow. Be more careful about overflow
8108 calculations, and distinguish size from memory overflow better.
8109 (receive_incremental_selection): When tracing, don't assume
8110 unsigned int is less than INT_MAX.
8111 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8112 harmful) conversions of unsigned short to int.
8113 (lisp_data_to_selection_data): Don't assume that integers
8114 in the range -65535 through -1 fit in an X unsigned short.
8115 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8116 result parameters unless successful. Rely on cons_to_unsigned
8117 to report problems with elements; the old code wasn't right anyway.
8118 (x_check_property_data): Check for int overflow; we cannot use
8119 a wider type due to X limits.
8120 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8151 * image.c (xpm_get_color_table_h):
8152 * lisp.h (hash_lookup, hash_put):
8153 * minibuf.c (Ftest_completion):
8154 Use ptrdiff_t for hash table indexes, not int (which is too
8155 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8156 32-bit --with-wide-int hosts).
8158 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8159 Add a FIXME comment about memory leaks.

8164 * character.h (CHAR_WIDTH):
8165 * indent.c (MULTIBYTE_BYTES_WIDTH):
8166 Use sanitize_char_width to avoid undefined and/or bad behavior
8167 with outlandish widths.
8168 * character.h (sanitize_tab_width): Rename from sanitize_width,
8169 now that we have two such functions. All uses changed.
8170 (sanitize_char_width): New inline function.
8172 Don't assume that tab-width fits in int.
8173 * character.h (sanitize_width): New inline function.
8174 (SANE_TAB_WIDTH): New macro.

8187 * xterm.c: Don't go over XClientMessageEvent limit.
8188 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8189 (x_send_scroll_bar_event): Likewise. Check that the size does not
8190 exceed limits imposed by XClientMessageEvent, as well as the usual
8191 ptrdiff_t and size_t limits.
8193 * keyboard.c: Overflow, signedness and related fixes.
8194 (make_lispy_movement): Use same integer type in forward decl
8195 that is used in the definition.
8196 (read_key_sequence, keyremap_step):
8197 Change bufsize argument back to int, undoing my 2011-03-30 change.
8198 We prefer signed types, and int is wide enough here.
8199 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8200 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8201 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8202 length, not size_t. Use ptrdiff_t for index, not int.
8203 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8204 possibility of integer overflow.
8206 Overflow, signedness and related fixes for images.
8208 * dispextern.h (struct it.stack[0].u.image.image_id)
8209 (struct_it.image_id, struct image.id, struct image_cache.size)

8215 * nsmenu.m (update_frame_tool_bar):
8216 * xdisp.c (calc_pixel_width_or_height):
8217 * xfns.c (image_cache_refcount):

8219 on typical 64-bit hosts.
8221 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8222 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
8223 Omit unnecessary casts to int.

8225 when the callers expect that.
8226 (image_ascent): Redo ascent calculation to avoid int overflow.
8227 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8228 (lookup_image): Remove unnecessary tests.
8229 (xbm_image_p): Locals are now of int, not EMACS_INT,
8230 since parse_image_check makes sure they fit into int.
8231 (png_load, gif_load, svg_load_image):
8232 Prefer int to unsigned where either will do.
8233 (tiff_handler): New function, combining the cores of the
8234 old tiff_error_handler and tiff_warning_handler.
8235 This function is rewritten to use vsnprintf and thereby avoid
8236 stack buffer overflows. It uses only the features of vsnprintf
8237 that are common to both POSIX and native Microsoft.
8238 (tiff_error_handler, tiff_warning_handler): Use it.
8239 (tiff_load, gif_load, imagemagick_load_image):
8240 Don't assume :index value fits in 'int'.
8241 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8242 (imagemagick_load_image): Check that crop parameters fit into
8243 the integer types that MagickCropImage accepts. Don't assume
8244 Vimagemagick_render_type has a nonnegative value. Don't assume
8245 size_t fits in 'long'.
8246 (gs_load): Use printmax_t to print the widest integers possible.
8247 Check for integer overflow when computing image height and width.
8249 2011-08-26 Eli Zaretskii <eliz@gnu.org>

8259 handle_single_display_spec, not just 1 or zero.
8260 (handle_single_display_spec): If the display spec is of the form
8261 `(space ...)', and specifies display in the text area, return 2
8263 (try_cursor_movement): Check for the need to scroll more
8264 accurately, and prefer exact match for point under bidi.
8265 Don't advance `row' beyond the last row of the window.
8267 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8268 into disp_prop; all users changed.
8270 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8271 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8272 for the text covered by the display property.
8274 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8276 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8283 buffers, return left-to-right.
8284 (set_cursor_from_row): Consider candidate row a win if its glyph
8285 represents a newline and point is on that newline. Fixes cursor
8286 positioning on the newline at EOL of R2L text within L2R
8287 paragraph, and vice versa.
8288 (try_cursor_movement): Check continued rows, in addition to
8289 continuation rows. Fixes unwarranted scroll when point enters a
8290 continued line of R2L text within an L2R paragraph, or vice versa.
8291 (cursor_row_p): Consider the case of point being equal to
8292 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8293 from the end of a short line to the beginning of a continued line
8294 of R2L text within L2R paragraph.
8295 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8296 composed characters.
8298 * bidi.c (bidi_check_type): Use xassert.
8299 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8302 2011-08-23 Eli Zaretskii <eliz@gnu.org>

8307 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8309 * nsfont.m (ns_otf_to_script): Fix typo.
8311 2011-08-22 Kenichi Handa <handa@m17n.org>
8313 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8314 extra slot even if the purpose is char-code-property-table.
8316 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8318 * xdisp.c (redisplay_window): When computing centering_position,
8319 account for the height of the header line. (Bug#8874)
8321 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8322 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8323 candidate is selected by the mouse, and that candidate has a
8324 composed character under the mouse.
8326 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8327 coordinates reported by pos-visible-in-window-p for a composed
8328 character in column zero.

8332 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8334 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8336 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8337 consider it a hit if to_charpos is anywhere in the range of the
8338 composed buffer positions.
8340 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8342 * image.c (gif_load): Don't assume that each subimage has the same
8343 dimensions as the base image. Handle disposal method that is
8344 "undefined" by the gif spec (Bug#9335).
8346 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8348 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8349 (Fcondition_case): Document `debug' symbol in error handler.
8351 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8353 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8354 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8355 from an Org mode buffer to a Speedbar frame.
8357 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8358 a composition, take its buffer position from IT->cmp_it.charpos.
8359 Fixes cursor positioning at the beginning of a line that begins
8360 with a composed character.
8362 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8364 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8365 character bidirectional type, use STRONG_L instead. Fixes crashes
8366 in a buffer produced by `describe-categories'.
8368 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8369 members before the level stack, so they would be saved and
8370 restored when copying iterator state. Fixes incorrect reordering
8371 around TABs covered by display properties.
8373 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8456 (ns_run_ascript): New function.
8457 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8458 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8459 the event loop. Get status from as_status (Bug#7276).
8461 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8462 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8463 the event loop (Bug#7276).

8489 (Fnetwork_interface_list): Allocate in increments of bytes instead
8490 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8491 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8493 (struct ifflag_def): notrailers is smart on OSX.
8494 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8495 Get hardware address with getifaddrs if available.

8499 * xdisp.c (iterate_out_of_display_property): xassert that
8500 IT->position is set to within IT->object's boundaries. Break from
8501 the loop as soon as EOB is reached; avoids infloops in redisplay
8502 when IT->position is set up wrongly due to some bug.
8503 Set IT->current to match the bidi iterator unconditionally.
8504 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8505 entry. Force push_it to save on the stack the current
8506 buffer/string position, to be restored by pop_it. Fix flags in
8507 the iterator structure wrt the object coming from a display
8508 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8509 properties. (Bug#9284)
8511 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8513 * fontset.c (fontset_get_font_group): Add proper type checks.

8528 properties and overlays.
8530 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8532 * editfns.c (Fset_time_zone_rule): Document relationship with the

8554 word-wrap under bidirectional display. (Bug#9224)
8556 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8557 is non-zero, even if the data buffer is NULL. Fixes a crash in
8558 vertical-motion with longlines-mode. (Bug#9254)
8560 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8562 * bidi.c <bidi_cache_total_alloc>: Now static.

8568 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8569 amount allocated this far in `bidi_cache_total_alloc'.
8570 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8571 non-zero, only free the data buffer without restoring the cache
8572 contents. All callers changed.

8576 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8577 (move_it_in_display_line, move_it_to)
8578 (move_it_vertically_backward, move_it_by_lines): Replace the call
8579 to xfree to an equivalent call to bidi_unshelve_cache.
8580 (move_it_in_display_line_to): Fix logic of returning

8659 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8661 (reseat_at_next_visible_line_start): Use the bidi iterator state
8662 returned by forward_to_next_line_start to restore the state of
8663 it->bidi_it after backing up to previous newline. (Bug#9212)

8667 * regex.c (re_comp): Protoize.
8668 (re_exec): Fix return type.
8669 (regexec): Fix type of `ret'. (Bug#9203)
8671 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8673 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8674 This is needed if max-image-size is a floating-point number.
8676 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8678 * print.c (print_object): Print empty symbol as ##.
8680 * lread.c (read1): Read ## as empty symbol.
8682 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8684 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8685 setting frame foreground color (Bug#9175).
8686 (x_set_background_color): Likewise.
8688 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8689 contents (Bug#9176).
8690 (EmacsTooltip -init): Remove bezels and add shadows to
8693 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8694 or scroll bar (Bug#8470).
8696 * nsfont.m (nsfont_open): Remove assignment to voffset and
8697 unnecessary vars hshink, expand, hd, full_height, min_height.
8698 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8700 * nsterm.h (nsfont_info): Remove voffset field.
8702 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8704 Implement strike-through and overline on NextStep (Bug#8863).
8706 * nsfont.m (nsfont_open): Use underline position provided by font,
8707 instead of hard-coded value of 2.
8708 (nsfont_draw): Call ns_draw_text_decoration instead.
8710 * nsterm.h: Add declaration for ns_draw_text_decoration.
8712 * nsterm.m (ns_draw_text_decoration): New function for drawing
8713 underline, overline, and strike-through.
8714 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8715 ns_draw_text_decoration. Change treatment of cursor drawing to
8716 accommodate underlining, etc.
8718 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8720 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8723 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8725 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8726 Without this fix, if a signal arrives just after memory fills up,
8727 'malloc' might be invoked reentrantly.
8729 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8730 In other words, assume that every image size is allowed, on non-X
8731 hosts. This assumption is probably wrong, but it lets Emacs compile.
8733 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8735 * regex.c (re_iswctype): Convert return values to boolean.
8737 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8739 * xdisp.c (compute_display_string_pos): Don't use cached display
8740 string position if the buffer had its restriction changed.
8743 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8745 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8747 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8749 Integer signedness and overflow and related fixes. (Bug#9079)
8751 * bidi.c: Integer size and overflow fixes.
8752 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8753 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8754 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8755 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8756 (bidi_find_other_level_edge):
8757 Use ptrdiff_t instead of EMACS_INT where either will do.
8758 This works better on 32-bit hosts configured --with-wide-int.
8759 (bidi_cache_ensure_space): Check for size-calculation overflow.
8760 Use % rather than repeated addition, for better worst-case speed.
8761 Don't set bidi_cache_size until after xrealloc returns, because it
8763 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8764 (bidi_cache_ensure_space): Also check that the bidi cache size
8765 does not exceed that of the largest Lisp string or buffer. See Eli
8766 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8768 * alloc.c (__malloc_size_t): Remove.
8769 All uses replaced by size_t. See Andreas Schwab's note
8770 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8772 * image.c: Improve checking for integer overflow.
8773 (check_image_size): Assume that f is nonnull, since
8774 it is always nonnull in practice. This is one less thing to
8775 worry about when checking for integer overflow later.
8776 (x_check_image_size): New function, which checks for integer
8777 overflow issues inside X.
8778 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8779 This removes the need for a memory_full check.
8780 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8781 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8782 (xbm_read_bitmap_data): Change locals back to 'int', since
8783 their values must fit in 'int'.
8784 (xpm_load_image, png_load, tiff_load):
8785 Invoke x_create_x_image_and_pixmap earlier,
8786 to avoid much needless work if the image is too large.
8787 (tiff_load): Treat overly large images as if
8788 x_create_x_image_and_pixmap failed, not as malloc failures.
8789 (gs_load): Use x_check_image_size.
8791 * gtkutil.c: Omit integer casts.
8792 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8793 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8795 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8797 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8798 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8799 would wrongly return t on a 64-bit host.
8801 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8802 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8803 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8804 and therefore cause GCC to emit a bogus diagnostic in some cases.
8806 * image.c: Integer signedness and overflow and related fixes.
8807 This is not an exhaustive set of fixes, but it's time to
8808 record what I've got.
8809 (lookup_pixel_color, check_image_size): Remove redundant decls.
8810 (check_image_size): Don't assume that arbitrary EMACS_INT values
8811 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8812 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8813 (tiff_load, imagemagick_load_image):
8814 Check for overflow in size calculations.
8815 (x_create_x_image_and_pixmap): Remove unnecessary test for
8816 xmalloc returning NULL; that can't happen.
8817 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8818 (xpm_color_bucket): Use better integer hashing function.
8819 (xpm_cache_color): Don't possibly over-allocate memory.
8820 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8821 (gif_memory_source):
8822 Use ptrdiff_t, not int or size_t, to record sizes.
8823 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8824 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8825 either works, as we prefer signed integers.
8826 (tiff_read_from_memory, tiff_write_from_memory):
8827 Return tsize_t, not size_t, since that's what the TIFF API wants.
8828 (tiff_read_from_memory): Don't fail simply because the read would
8829 go past EOF; instead, return a short read.
8830 (tiff_load): Omit no-longer-needed casts.
8831 (Fimagemagick_types): Don't assume size fits into 'int'.
8833 Improve hashing quality when configured --with-wide-int.
8834 * fns.c (hash_string): New function, taken from sxhash_string.
8835 Do not discard information about ASCII character case; this
8836 discarding is no longer needed.
8837 (sxhash-string): Use it. Change sig to match it. Caller changed.
8838 * lisp.h: Declare it.
8839 * lread.c (hash_string): Remove, since we now use fns.c's version.
8840 The fns.c version returns a wider integer if --with-wide-int is
8841 specified, so this should help the quality of the hashing a bit.
8843 * emacs.c: Integer overflow minor fix.
8844 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8845 Define only if GNU_LINUX.
8846 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8848 * dispnew.c: Integer signedness and overflow fixes.
8849 Remove unnecessary forward decls, that were a maintenance hassle.
8850 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8852 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8853 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8854 (prepare_desired_row, line_draw_cost):
8855 Use int, not unsigned, where either works.
8856 (save_current_matrix, restore_current_matrix):
8857 Use ptrdiff_t, not size_t, where either works.
8858 (init_display): Check for overflow more accurately, and without
8859 relying on undefined behavior.
8861 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8862 Remove, replacing with the new symbols in lisp.h. All uses changed.
8863 * fileio.c (make_temp_name):
8864 * filelock.c (lock_file_1, lock_file):
8865 * xdisp.c (message_dolog):
8866 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8867 Use pMd etc. instead.
8868 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8869 replacing the pWIDE etc. symbols removed from editfns.c.
8871 * keyboard.h (num_input_events): Now uintmax_t.
8872 This is (very slightly) less likely to mess up due to wraparound.
8875 * buffer.c: Integer signedness fixes.
8876 (alloc_buffer_text, enlarge_buffer_text):
8877 Use ptrdiff_t rather than size_t when either will do, as we prefer
8880 * alloc.c: Integer signedness and overflow fixes.
8881 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8882 (__malloc_size_t): Default to size_t, not to int.
8883 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8884 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8885 Prefer ptrdiff_t to size_t when either would do, as we prefer
8887 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8888 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8889 Now const. Initialize with values that are in range even if char
8891 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8892 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8893 These functions do the right thing with sizes > 2**32.
8894 (check_depth): Now ptrdiff_t, not int.
8895 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8896 Adjust to new way of storing sizes. Check for size overflow bugs
8898 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8899 slightly wrong anyway, as it missed one instance of
8900 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8901 (refill_memory_reserve): Omit needless cast to size_t.
8902 (mark_object_loop_halt): Mark as externally visible.
8904 * xselect.c: Integer signedness and overflow fixes.
8905 (Fx_register_dnd_atom, x_handle_dnd_message):
8906 Use ptrdiff_t, not size_t, since we prefer signed.
8907 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8908 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8909 x_dnd_atoms_size and x_dnd_atoms_length.
8911 * doprnt.c: Prefer signed to unsigned when either works.
8913 * doprnt.c (doprnt):
8915 * xdisp.c (vmessage):
8916 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8917 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8918 prefer signed arithmetic to avoid comparison confusion.
8919 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8920 but is a bit tricky.
8922 Assume freestanding C89 headers, string.h, stdlib.h.
8923 * data.c, doprnt.c, floatfns.c, print.c:
8924 Include float.h unconditionally.
8925 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8926 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8927 * regex.c: Likewise for stddef.h, string.h.
8928 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8929 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8930 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8931 (STDC_HEADERS): Remove obsolete defines.
8932 * sysdep.c: Include limits.h unconditionally.
8934 Assume support for memcmp, memcpy, memmove, memset.
8935 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8936 * regex.c (memcmp, memcpy):
8937 Remove; we assume C89 now.
8939 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8940 (__malloc_safe_bcopy): Remove; no longer needed.
8942 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8943 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8944 well either way, and we prefer signed to unsigned.
8946 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8948 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8949 closes the connection while we're reading (bug#9182).
8951 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8953 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8954 are specified (Bug#9168).
8956 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8958 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8959 Found by GCC static checking and --with-wide-int on a 32-bit host.
8961 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8963 * xdisp.c (compute_display_string_pos): Fix logic of caching
8964 previous display string position. Initialize cached_prev_pos to
8965 -1. Fixes slow-down at the beginning of a buffer.
8967 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8969 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8970 for attrs[LFACE_FONTSET_INDEX].
8972 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8974 * xml.c (parse_region): Remove unused local
8975 that was recently introduced.
8977 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8979 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8980 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8982 * xdisp.c (move_it_in_display_line_to): Record the best matching
8983 position for TO_CHARPOS while scanning the line, and restore it on
8984 exit if none of the characters scanned was an exact match.
8985 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8986 when exact match is impossible due to invisible text, and the
8987 lines are truncated.
8989 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8991 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8994 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8996 Fix a significant slow-down of cursor motion with C-n, C-p,
8997 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8998 auto-repeat under bidi redisplay in fontified buffers.
8999 * xdisp.c (compute_stop_pos_backwards): New function.
9000 (next_element_from_buffer): Call compute_stop_pos_backwards to
9001 find a suitable prev_stop when we find ourselves before
9003 (reseat): Don't look for prev_stop, as that could mean a very long
9005 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9006 <cached_disp_overlay_modiff>: Cache for last found display string
9008 (compute_display_string_pos): Return the cached position if asked
9009 about the same buffer in the same area of character positions, and
9010 the buffer wasn't changed since the time the display string
9011 position was cached.
9013 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9015 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9016 is an integer, which is important for empty lines. (Bug#9149)
9018 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9020 * frame.c (Fmodify_frame_parameters): In tty case, update the
9021 default face if necessary (Bug#4238).
9023 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9025 * editfns.c (Fstring_to_char): No need to explain what a character
9026 is in the docstring (Bug#6576).
9028 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9030 * xml.c (parse_region): Make sure we always return a tree.
9032 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9034 * xml.c (parse_region): If a document contains only comments,
9037 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9039 * xml.c (make_dom): Return comments, too.
9041 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9044 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9045 and the surrounding thread.
9046 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9047 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9048 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9050 * s/openbsd.h (BROKEN_SIGIO): Define.
9051 * unexelf.c (unexec) [__OpenBSD__]:
9052 Don't update the .mdebug section of the Alpha COFF symbol table.
9054 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9056 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9059 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9061 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9062 This fixes some race conditions on the permissions of any newly
9065 * alloc.c (valid_pointer_p): Use pipe, not open.
9066 This fixes some permissions issues when debugging.
9068 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9069 If fchown fails to set both uid and gid, try to set just gid,
9070 as that is sometimes allowed. Adjust the file's mode to eliminate
9071 setuid or setgid bits that are inappropriate if fchown fails.
9073 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9075 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9076 to compare Lisp_Objects.
9077 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9078 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9079 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9081 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9083 * lread.c (read_integer): Unread even EOF character.
9084 (read1): Likewise. Properly record start position of symbol.
9086 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9087 symbol character follows.
9089 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9091 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9092 This works around a problem with the previous change to Fcopy_file.
9093 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9094 and without this change, GCC might complain about discarding
9095 fchown's return value.
9097 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9099 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9101 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9103 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9105 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9107 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9108 it's used from the C level.
9110 * process.c: Use the same condition for POLL_FOR_INPUT in both
9111 keyboard.c and process.c (bug#1858).
9113 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9115 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9116 (Fgnutls_boot): Use it.
9118 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9120 * doc.c (Fsubstitute_command_keys): Revert last change.
9122 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9124 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9125 quotes the next character, and doesn't affect other longer
9126 sequences (bug#8935).
9128 * lread.c (syms_of_lread): Clarify that is isn't only

9193 the iterator is before prev_stop.
9194 (init_iterator): Initialize bidi_p from the default value of

9671 (clone_per_buffer_values): Don't assume that

9712 Random fixes. E.g., (random) never returned negative values.
9713 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9714 subseconds part to the entropy, as that's a bit more random.
9715 Prefer signed to unsigned, since the signedness doesn't matter and
9716 in general we prefer signed. When given a limit, use a
9717 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9718 latter isn't right if USE_2_TAGS_FOR_INTS.
9719 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9720 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9732 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9733 This is more efficient than Ffile_directory_p and avoids a minor race.
9735 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9737 * buffer.c (Foverlay_put): Say what the return value is
9740 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9741 is a directory before asking whether to use the file name
9743 (barf_or_query_if_file_exists): Make the "File is a directory"
9744 error be more correct.
9746 * fns.c (Frequire): Remove the mention of the .gz files, since
9747 that's installation-specific, but keep the mention of
9748 `get-load-suffixes'.
9750 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9752 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9763 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9764 Also (re)move comments that are misplaced or no longer relevant.

9865 * eval.c (struct backtrace): Simplify and port the data structure.
9866 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9867 signed bit field, as this assumption is not portable and it makes
9868 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9869 "char debug_on_exit : 1" as this is not portable either; instead,
9870 use the portable "unsigned int debug_on_exit : 1". Remove unused
9871 member evalargs. Remove obsolete comments about cc bombing out.
9873 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

10044 for sizes. Check for string overflow more accurately.
10045 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10047 * macros.c: Integer and buffer overflow fixes.
10048 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10049 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10050 Use ptrdiff_t, not int, for sizes.
10051 Don't increment bufsize until after realloc succeeds.
10052 Check for size-calculation overflow.
10053 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10055 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10057 * lread.c: Integer overflow fixes.
10058 (read_integer): Radix is now EMACS_INT, not int,
10059 to improve quality of diagnostics for out-of-range radices.
10060 Calculate buffer size correctly for out-of-range radices.
10061 (read1): Check for integer overflow in radices, and in
10062 read-circle numbers.
10063 (read_escape): Avoid int overflow.
10064 (Fload, openp, read_buffer_size, read1)
10065 (substitute_object_recurse, read_vector, read_list, map_obarray):
10066 Use ptrdiff_t, not int, for sizes.
10067 (read1): Use EMACS_INT, not int, for sizes.

10081 2011-06-22 Leo Liu <sdl.web@gmail.com>
10083 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10084 Move to minibuffer.el.
10086 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10088 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10089 The following patches are for when GLYPH_DEBUG && !XASSERT.
10090 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10091 * dispnew.c (flush_stdout):
10092 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10093 Mark as externally visible.
10094 * dispnew.c (check_window_matrix_pointers): Now static.
10095 * dispnew.c (window_to_frame_vpos):
10096 * xfns.c (unwind_create_frame):
10097 * xterm.c (x_check_font): Remove unused local.
10098 * scroll.c (CHECK_BOUNDS):
10099 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10100 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10101 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10102 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10103 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10105 (debug_method_add): Use va_list and vsprintf rather than relying
10106 on undefined behavior with wrong number of arguments.
10107 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10108 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10109 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10110 since we're not interested in debugging glyphs with old libraries.
10111 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10112 GCC 4.6.0's static checking.
10114 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10116 Integer overflow and signedness fixes (Bug#8873).

10125 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10126 (x_create_bitmap_from_xpm_data):
10127 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10128 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10130 * xfaces.c (load_pixmap):
10131 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10132 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10133 (.bitmaps_last, struct x_output.icon_bitmap):
10134 Use ptrdiff_t, not int, for bitmap indexes.
10135 (x_allocate_bitmap_record): Check for size overflow.
10136 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10138 Use ptrdiff_t, not int, for overlay counts.
10139 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10140 * editfns.c (overlays_around, get_pos_property):
10141 * textprop.c (get_char_property_and_overlay):
10142 * xdisp.c (next_overlay_change, note_mouse_highlight):
10143 * xfaces.c (face_at_buffer_position):
10144 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10145 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10146 (Fnext_overlay_change, Fprevious_overlay_change)
10147 (mouse_face_overlay_overlaps, Foverlays_in):
10148 Use ptrdiff_t, not int, for sizes.
10149 (overlays_at, overlays_in): Check for size-calculation overflow.
10151 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10153 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10154 (x_session_initialize): Do not assume string length fits in int.
10156 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10157 This is unlikely, but can occur if DPI is outlandish.
10159 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10160 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10162 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10163 * xrdb.c (magic_file_p, search_magic_path):
10164 Omit last arg SUFFIX; it was always 0. All callers changed.
10165 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10167 * xfont.c (xfont_match): Avoid need for strlen.
10169 * xfns.c: Don't assume strlen fits in int.
10170 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10172 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10173 not unsigned long, as we prefer signed integers. All callers changed.
10174 Detect integer overflow in repeat count.
10175 (message_dolog): Don't assume print length fits in 39 bytes.
10176 (display_mode_element): Don't assume strlen fits in int.
10178 * termcap.c: Don't assume sizes fit in int and never overflow.
10179 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10180 (gobble_line): Check for size-calculation overflow.
10182 * minibuf.c (Fread_buffer):
10183 * lread.c (intern, intern_c_string):
10184 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10185 Don't assume string length fits in int.
10187 * keyboard.c (parse_tool_bar_item):
10188 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10190 * font.c: Don't assume string length fits in int.
10191 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10192 Use ptrdiff_t, not int.
10193 (font_intern_prop): Don't assume string length fits in int.
10194 Don't assume integer property fits in fixnum.
10195 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10197 * filelock.c: Fix some buffer overrun and integer overflow issues.
10198 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10199 Reformulate so as not to need the command string.
10200 Invoke gzip -cd rather than gunzip, as it's more portable.
10201 (lock_info_type, lock_file_1, lock_file):
10202 Don't assume pid_t and time_t fit in unsigned long.
10203 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10204 (current_lock_owner): Prefer signed type for sizes.
10205 Use memcpy, not strncpy, where memcpy is what is really wanted.
10206 Don't assume (via atoi) that time_t and pid_t fit in int.
10207 Check for time_t and/or pid_t out of range, e.g., via a network share.
10208 Don't alloca where an auto var works fine.
10210 * fileio.c: Fix some integer overflow issues.
10211 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10212 Don't assume string length fits in int.
10213 (directory_file_name): Don't assume string length fits in long.
10214 (make_temp_name): Don't assume pid fits in int, or that its print
10215 length is less than 20.
10217 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10219 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10221 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10223 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10224 We prefer signed integers, even for size calculations.
10226 * emacs.c: Don't assume string length fits in 'int'.
10227 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10228 (main): Don't invoke strlen when not needed.
10230 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10231 (XD_DEBUG_MESSAGE): Don't waste a byte.
10233 * callproc.c (getenv_internal_1, getenv_internal)
10234 (Fgetenv_internal):
10235 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10237 * lread.c (invalid_syntax): Omit length argument.
10238 All uses changed. This doesn't fix a bug, but it simplifies the
10239 code away from its former Hollerith-constant appearance, and it's
10240 one less 'int' to worry about when looking at integer-overflow issues.
10241 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10243 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10244 This didn't break anything, but it didn't help either.
10245 It's confusing to put a bogus integer in a place where the actual
10246 value does not matter.
10247 (LIST_END_P): Remove unused macro and its bogus comment.
10248 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10250 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10251 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10253 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10254 We prefer signed types, and the value cannot exceed the EMACS_INT
10255 range anyway (because otherwise the length would not be representable).
10256 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10257 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10258 This avoids a GCC warning when WIDE_EMACS_INT.
10260 * indent.c (sane_tab_width): New function.
10261 (current_column, scan_for_column, Findent_to, position_indentation)
10262 (compute_motion): Use it. This is just for clarity.
10263 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10265 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10267 * lisp.h (lint_assume): New macro.
10268 * composite.c (composition_gstring_put_cache):
10269 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10271 * editfns.c, insdel.c:
10272 Omit unnecessary forward decls, to simplify future changes.
10274 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10276 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10278 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10279 Use much-faster test for byte-length change.
10280 Don't assume string byte-length fits in 'int'.
10281 Check that character arg fits in 'int'.
10282 (mapcar1): Declare byte as byte, for clarity.
10284 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10286 * fns.c (concat): Catch string overflow earlier.
10287 Do not rely on integer wraparound.
10289 * dispextern.h (struct it.overlay_strings_charpos)
10290 (struct it.selective): Now EMACS_INT, not int.
10291 * xdisp.c (forward_to_next_line_start)
10292 (back_to_previous_visible_line_start)
10293 (reseat_at_next_visible_line_start, next_element_from_buffer):
10294 Don't arbitrarily truncate the value of 'selective' to int.
10296 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10298 * composite.c: Don't truncate sizes to 'int'.
10299 (composition_gstring_p, composition_reseat_it)
10300 (composition_adjust_point): Use EMACS_INT, not int.
10301 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10302 not EMACS_UINT, for indexes.
10304 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10306 * buffer.c: Include <verify.h>.
10307 (struct sortvec.priority, struct sortstr.priority):
10308 Now EMACS_INT, not int.
10309 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10310 (struct sortstr.size, record_overlay_string)
10311 (struct sortstrlist.size, struct sortlist.used):
10312 Don't truncate size to int.
10313 (record_overlay_string): Check for size-calculation overflow.
10314 (init_buffer_once): Check at compile-time, not run-time.
10316 2011-06-22 Jim Meyering <meyering@redhat.com>
10318 Don't leak an XBM-image-sized buffer
10319 * image.c (xbm_load): Free the image buffer after using it.
10321 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10324 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10325 that Sun C diagnosed.
10326 * fns.c (secure_hash): Fix pointer signedness issue.
10327 * intervals.c (static_offset_intervals): New function.
10328 (offset_intervals): Use it.
10330 2011-06-21 Leo Liu <sdl.web@gmail.com>
10333 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10336 * fns.c (secure_hash): Rename from crypto_hash_function and change
10337 the first arg to accept symbols.
10338 (Fsecure_hash): New primitive.
10339 (syms_of_fns): New symbols.
10341 2011-06-20 Deniz Dogan <deniz@dogan.se>
10343 * process.c (Fset_process_buffer): Clarify return value in
10346 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10348 * dispnew.c (add_window_display_history): Use BVAR.
10350 * xdisp.c (debug_method_add): Use BVAR.
10351 (check_window_end, dump_glyph_matrix, dump_glyph)
10352 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10354 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10357 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10358 check till after the cache is created in init_frame_faces.
10360 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10362 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10364 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10366 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10367 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10368 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10370 Improve buffer-overflow checking (Bug#8873).
10371 * fileio.c (Finsert_file_contents):
10372 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10373 Remove the old (too-loose) buffer overflow checks.
10374 They weren't needed, since make_gap checks for buffer overflow.
10375 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10376 The old code merely checked for Emacs fixnum overflow, and relied
10377 on undefined (wraparound) behavior. The new code avoids undefined
10378 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10380 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10381 Tune. Don't use wider integers than needed. Don't use alloca.
10382 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10384 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10386 * insdel.c, lisp.h (buffer_overflow): New function.
10387 (insert_from_buffer_1, replace_range, replace_range_2):
10388 * insdel.c (make_gap_larger):
10389 * editfns.c (Finsert_char):
10390 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10392 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10394 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10396 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10398 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10399 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10401 * fileio.c: Don't assume EMACS_INT fits in off_t.
10402 (emacs_lseek): New static function.
10403 (Finsert_file_contents, Fwrite_region): Use it.
10404 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10406 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10408 * fns.c: Don't overflow int when computing a list length.
10409 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10410 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10411 truncation on 64-bit hosts. Check for QUIT every
10412 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10413 faster and is responsive enough.
10414 (Flength): Report an error instead of overflowing an integer.
10415 (Fsafe_length): Return a float if the value is not representable
10416 as a fixnum. This shouldn't happen except in contrived situations.
10417 (Fnthcdr, Fsort): Don't assume list length fits in int.
10418 (Fcopy_sequence): Don't assume vector length fits in int.
10420 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10421 (header_size, word_size): New constants.
10422 (allocate_vectorlike): Don't check size overflow here.
10423 (allocate_vector): Check it here instead, since this is the only
10424 caller of allocate_vectorlike that could cause overflow.
10425 Check that the new vector's length is representable as a fixnum.
10427 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10428 The previous code was bogus. For example, next_almost_prime (32)
10429 returned 39, which is undesirable as it is a multiple of 3; and
10430 next_almost_prime (24) returned 25, which is a multiple of 5 so
10431 why was the code bothering to check for multiples of 7?
10433 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10435 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10437 Variadic C functions now count arguments with ptrdiff_t.
10438 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10439 Back then I didn't know that the Emacs coding style prefers signed int.
10440 Also, in the meantime I found a few more instances where arguments
10441 were being counted with int, which may truncate counts on 64-bit
10442 machines, or EMACS_INT, which may be unnecessarily wide.
10443 * lisp.h (struct Lisp_Subr.function.aMANY)
10444 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10445 Arg counts are now ptrdiff_t, not size_t.
10446 All variadic functions and their callers changed accordingly.
10447 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10448 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10449 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10450 * callint.c (Fcall_interactively): Check arg count for overflow,
10451 to avoid potential buffer overrun. Use signed char, not 'int',
10452 for 'varies' array, so that we needn't bother to check its size
10453 calculation for overflow.
10454 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10455 * eval.c (apply_lambda):
10456 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10457 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10458 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10460 * callint.c (Fcall_interactively): Don't use index var as event count.
10462 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10463 * mem-limits.h (SIZE): Remove; no longer used.
10465 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10467 Remove unnecessary casts.
10468 * xterm.c (x_term_init):
10469 * xfns.c (x_set_border_pixel):
10470 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10471 These aren't needed now that we assume ANSI C.
10473 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10474 It's more likely to cause problems (due to unsigned overflow)
10477 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10479 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10481 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10483 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10485 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10487 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10489 GLYPH_CODE_FACE returns EMACS_INT, not int.
10490 * dispextern.h (merge_faces):
10491 * xfaces.c (merge_faces):
10492 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10493 Don't assume EMACS_INT fits in int.
10495 * character.h (CHAR_VALID_P): Remove unused parameter.
10496 * fontset.c, lisp.h, xdisp.c: All uses changed.
10498 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10500 * fns.c (concat): Minor tuning based on overflow analysis.
10501 This doesn't fix any bugs. Use int to hold character, instead
10502 of constantly refetching from Emacs object. Use XFASTINT, not
10503 XINT, for value known to be a character. Don't bother comparing
10504 a single byte to 0400, as it's always less.
10506 * floatfns.c (Fexpt):
10507 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10509 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10512 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10514 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10515 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10516 incorrectly succeed when S was a string, because 4294967386 was
10517 truncated before it was used.
10519 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10520 Otherwise, an out-of-range integer could cause undefined behavior
10523 * composite.c: Use int, not EMACS_INT, for characters.
10524 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10525 EMACS_INT, for values that are known to be in character range.
10526 This doesn't fix any bugs but is the usual style inside Emacs and
10527 may generate better code on 32-bit machines.
10529 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10530 This is for reasons similar to the recent CHAR_STRING fix.
10531 * charset.c (Fencode_char): Check that character arg is actually
10532 a character. Pass an int to ENCODE_CHAR.
10533 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10534 wider than 'int', as a compile-time check to prevent future regressions
10537 * character.c (char_string): Remove unnecessary casts.
10539 Make sure a 64-bit char is never passed to CHAR_STRING.
10540 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10541 by silently ignoring the top 32 bits, allowing some values
10542 that were far too large to be valid characters.
10543 * character.h: Include <verify.h>.
10544 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10545 arguments are no wider than unsigned, as a compile-time check
10546 to prevent future regressions in this area.
10548 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10549 (Fsubst_char_in_region):
10551 * xdisp.c (decode_mode_spec_coding):
10552 Adjust to CHAR_STRING's new requirement.
10553 * editfns.c (Finsert_char, Fsubst_char_in_region):
10554 * fns.c (concat): Check that character args are actually
10555 characters. Without this test, these functions did the wrong
10556 thing with wildly out-of-range values on 64-bit hosts.
10558 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10559 These casts should not be needed on 32-bit hosts, either.
10560 * keyboard.c (read_char):
10561 * lread.c (Fload): Remove casts to unsigned.
10563 * lisp.h (UNSIGNED_CMP): New macro.
10564 This fixes comparison bugs on 64-bit hosts.
10565 (ASCII_CHAR_P): Use it.
10566 * casefiddle.c (casify_object):
10567 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10568 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10569 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10570 * dispextern.h (FACE_FROM_ID):
10571 * keyboard.c (read_char): Use UNSIGNED_CMP.
10573 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10574 not to EMACS_INT, to avoid GCC warning.
10576 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10578 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10579 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10580 isn't needed on 32-bit machines.
10582 * buffer.c (Fgenerate_new_buffer_name):
10583 Use EMACS_INT for count, not int.
10584 (advance_to_char_boundary): Return EMACS_INT, not int.
10586 * data.c (Qcompiled_function): Now static.
10588 * window.c (window_body_lines): Now static.
10590 * image.c (gif_load): Rename local to avoid shadowing.
10592 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10593 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10594 * alloc.c (make_save_value): Integer argument is now of type
10595 ptrdiff_t, not int.
10596 (mark_object): Use ptrdiff_t, not int.
10597 * lisp.h (pD): New macro.
10598 * print.c (print_object): Use it.
10600 * alloc.c: Use EMACS_INT, not int, to count objects.
10601 (total_conses, total_markers, total_symbols, total_vector_size)
10602 (total_free_conses, total_free_markers, total_free_symbols)
10603 (total_free_floats, total_floats, total_free_intervals)
10604 (total_intervals, total_strings, total_free_strings):
10605 Now EMACS_INT, not int. All uses changed.
10606 (Fgarbage_collect): Compute overall total using a double, so that
10607 integer overflow is less likely to be a problem. Check for overflow
10608 when converting back to an integer.
10609 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10610 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10611 These were 'int' variables that could overflow on 64-bit hosts;
10612 they were never used, so remove them instead of repairing them.
10613 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10614 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10615 Previously, this ceilinged at INT_MAX, but that doesn't work on
10617 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10619 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10620 (allocate_vectorlike): Check for ptrdiff_t overflow.
10621 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10622 when a (possibly-narrower) signed value would do just as well.
10623 We prefer using signed arithmetic, to avoid comparison confusion.
10625 * alloc.c: Catch some string size overflows that we were missing.
10626 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10627 for convenience in STRING_BYTES_MAX.
10628 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10629 The definition here is exact; the one in lisp.h was approximate.
10630 (allocate_string_data): Check for string overflow. This catches
10631 some instances we weren't catching before. Also, it catches
10632 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10633 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10634 and ptrdiff_t and EMACS_INT are both 64 bits.
10636 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10637 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10638 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10640 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10642 * alloc.c (Fmake_string): Check for out-of-range init.
10644 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10646 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10648 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10650 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10651 xg_get_default_scrollbar_width.
10653 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10654 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10655 (style_changed_cb): Call update_theme_scrollbar_width and call
10656 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10657 all frames (Bug#8505).
10658 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10659 Call gtk_window_set_resizable if HAVE_GTK3.

10661 and height if HAVE_GTK3 (Bug#8505).
10662 (scroll_bar_width_for_theme): New variable.
10663 (update_theme_scrollbar_width): New function.
10664 (xg_get_default_scrollbar_width): Move code to
10665 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10666 (xg_initialize): Call update_theme_scrollbar_width.
10668 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10670 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10672 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10674 * frame.c (make_frame): Call other_buffer_safely instead of
10677 * window.c (temp_output_buffer_show): Call display_buffer with
10678 second argument Vtemp_buffer_show_specifiers and reset latter
10679 immediately after the call.
10680 (Vtemp_buffer_show_specifiers): New variable.
10681 (auto_window_vscroll_p, next_screen_context_lines)
10682 (Vscroll_preserve_screen_position): Remove leading asterisks from

10865 Remove static from declaration of Qdelete_window, it's
10866 temporarily needed by Fbury_buffer.
10867 (replace_window): Don't assign orig_top_line and

10872 Replace Fdelete_window calls with calls to Qdelete_window.
10873 (Fdelete_other_windows): Remove. Deleting other windows is

11233 (display_prop_intangible_p): Reimplement to call
11234 handle_display_spec instead of single_display_spec_intangible_p.

11246 value of a `display' property is a "replacing spec".
11247 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11248 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11276 All callers changed. (Bug#8762)
11278 * gnutls.c: Use Emacs's memory allocators.
11279 Without this change, the gnutls library would invoke malloc etc.
11280 directly, which causes problems on non-SYNC_INPUT hosts, and which
11281 runs afoul of improving memory_full behavior. (Bug#8761)
11282 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11283 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11284 xfree instead of the default malloc, realloc, free.
11285 (Fgnutls_boot): No need to check for memory allocation failure,
11286 since xmalloc does that for us.

11309 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11310 * alloc.c (allocate_vectorlike):
11311 Check for overflow in vector size calculations.
11312 * ccl.c (ccl_driver):
11313 Check for overflow when converting EMACS_INT to int.

11315 need to be updated by these changes.
11316 * fns.c (make_hash_table, maybe_resize_hash_table):
11317 Check for integer overflow with large hash tables.
11318 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11319 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11320 (SXHASH_REDUCE): New macro.
11321 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11322 Use it instead of discarding useful hash info with large hash values.
11323 (sxhash_float): New function.
11324 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11325 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11326 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11327 Rewrite to use FIXNUM_BITS, as this simplifies things.
11328 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11329 Adjust signatures to match updated version of code.
11330 (consing_since_gc): Now EMACS_INT, since a single hash table can
11331 use more than INT_MAX bytes.

11342 Call minibuffer-inactive-mode.
11344 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11346 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11347 Update dependencies.
11349 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11351 * data.c (init_data): Remove code for UTS, this system is not
11354 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11356 Don't force ./temacs to start in terminal mode.
11358 * frame.c (make_initial_frame): Initialize faces in all cases, not
11359 only when CANNOT_DUMP is defined.
11360 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11362 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11364 * dispnew.c (add_window_display_history): Use const for the string
11365 pointer. Remove declaration, not needed.
11367 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11369 Use 'inline', not 'INLINE'.
11370 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11371 * alloc.c, fontset.c (INLINE): Remove.
11372 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11373 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11374 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11375 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11376 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11378 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11380 Make it possible to run ./temacs.
11382 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11383 syms_of_callproc does the same thing. Remove test for
11384 "initialized", do it in the caller.
11385 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11387 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11389 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11390 (read_minibuf): Use get_minibuffer.
11391 (syms_of_minibuf): Use DEFSYM.
11392 (Qmetadata): New var.
11393 * data.c (Qbuffer): Don't make it static.
11394 (syms_of_data): Use DEFSYM.
11396 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11398 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11399 (CCL_CODE_MIN): New macro.
11401 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11403 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11405 * eval.c (Qdebug): Now static.
11406 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11407 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11408 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11410 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11412 * image.c: Various fixes to ImageMagick code comments.
11413 (Fimagemagick_types): Doc fix.
11415 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11417 Minor fixes prompted by GCC 4.6.0 warnings.
11419 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11421 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11422 (x_clipboard_manager_save_all): Move extern decl to ...
11423 * xterm.h: ... here, so that it can be checked for consistency.
11425 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11427 * xselect.c (x_clipboard_manager_save_frame)
11428 (x_clipboard_manager_save_all): New functions.
11429 (Fx_clipboard_manager_save): Lisp function deleted.
11431 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11432 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11434 * xterm.h: Update prototype.
11436 2011-05-28 William Xu <william.xwl@gmail.com>
11438 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11439 exiting (Bug#8239).
11441 2011-05-28 Jim Meyering <meyering@redhat.com>
11443 Avoid a sign-extension bug in crypto_hash_function.
11444 * fns.c (to_uchar): Define.
11445 (crypto_hash_function): Use it to convert some newly-signed
11446 variables to unsigned, to avoid sign-extension bugs. For example,
11447 without this change, (md5 "truc") would evaluate to
11448 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11449 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11450 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11452 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11454 Integer overflow fixes.
11456 * dbusbind.c: Serial number integer overflow fixes.
11457 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11458 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11459 to hold a serial number that is too large for a fixnum.
11460 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11461 Check for serial numbers out of range. Decode any serial number
11462 that was so large that it became a float. (Bug#8722)
11464 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11465 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11466 Use XFASTINT rather than XUINT when numbers are nonnegative.
11467 (xd_append_arg, Fdbus_method_return_internal):
11468 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11469 arguments, check that Lisp number is nonnegative, rather than
11470 silently wrapping negative numbers around. (Bug#8722)
11471 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11474 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11476 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11478 ccl: Add integer overflow checks.
11479 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11480 (IN_INT_RANGE): New macros.
11481 (ccl_driver): Use them to check for integer overflow when
11482 decoding a CCL program. Many of the new checks are whether XINT (x)
11483 fits in int; it doesn't always, on 64-bit hosts. The new version
11484 doesn't catch all possible integer overflows, but it's an
11485 improvement. (Bug#8719)
11487 * alloc.c (make_event_array): Use XINT, not XUINT.
11488 There's no need for unsigned here.
11490 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11491 This follows up to the 2011-05-06 change that substituted uintptr_t
11492 for EMACS_INT. This case wasn't caught back then.
11494 Rework Fformat to avoid integer overflow issues.
11495 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11496 now (part of C89). Include <verify.h>.
11497 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11498 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11499 (Fformat): Avoid the prepass trying to compute sizes; it was only
11500 approximate and thus did not catch overflow reliably. Instead, walk
11501 through the format just once, formatting and computing sizes as we go,
11502 checking for integer overflow at every step, and allocating a larger
11503 buffer as needed. Keep track separately whether the format is
11504 multibyte. Keep only the most-recently calculated precision, rather
11505 than them all. Record whether each argument has been converted to
11506 string. Use EMACS_INT, not int, for byte and char and arg counts.
11507 Support field widths and precisions larger than INT_MAX. Avoid
11508 sprintf's undefined behavior with conversion specifications such as %#d
11509 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11510 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11511 formatting out-of-range floating point numbers with int
11512 formats. (Bug#8668)
11514 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11516 * data.c: Avoid integer truncation in expressions involving floats.
11517 * data.c: Include <intprops.h>.
11518 (arith_driver): When there's an integer overflow in an expression
11519 involving floating point, convert the integers to floating point
11520 so that the resulting value does not suffer from catastrophic
11521 integer truncation. For example, on a 64-bit host (* 4
11522 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11523 Do not rely on undefined behavior after integer overflow.
11525 merge count_size_as_multibyte, parse_str_to_multibyte
11526 * character.c, character.h (count_size_as_multibyte):
11527 Rename from parse_str_to_multibyte; all uses changed.
11528 Check for integer overflow.
11529 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11530 since it's now a duplicate of the other. This is more of
11531 a character than a buffer op, so better that it's in character.c.
11532 * fns.c, print.c: Adjust to above changes.
11534 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11536 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11538 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11540 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11541 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11542 (x_clipboard_manager_save): Now static.
11543 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11545 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11546 (crypto_hash_function): Now static.
11547 Fix pointer signedness problems. Avoid unnecessary initializations.
11549 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11551 * termhooks.h (Vselection_alist): Make it terminal-local.
11553 * terminal.c (create_terminal): Initialize it.
11555 * xselect.c: Support for clipboard managers.
11556 (Vselection_alist): Move to termhooks.h as terminal-local var.
11557 (LOCAL_SELECTION): New macro.
11558 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11559 (symbol_to_x_atom): Remove gratuitous arg.
11560 (x_handle_selection_request, lisp_data_to_selection_data)
11561 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11562 (x_own_selection, x_get_local_selection, x_convert_selection):
11563 New arg, specifying work frame. Use terminal-local Vselection_alist.
11564 (some_frame_on_display): Delete unused function.
11565 (Fx_own_selection_internal, Fx_get_selection_internal)
11566 (Fx_disown_selection_internal, Fx_selection_owner_p)
11567 (Fx_selection_exists_p): New optional frame arg.
11568 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11569 (x_handle_selection_clear): Don't treat other terminals with the
11570 same keyboard specially. Use the terminal-local Vselection_alist.
11571 (x_clear_frame_selections): Use Frun_hook_with_args.
11573 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11575 * xterm.h: Add support for those atoms.
11577 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11579 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11580 (converted_selections, conversion_fail_tag): New global variables.
11581 (x_selection_request_lisp_error): Free the above.
11582 (x_get_local_selection): Remove unnecessary code.
11583 (x_reply_selection_request): Args changed; handle arbitrary array
11584 of converted selections stored in converted_selections.
11585 Separate the XChangeProperty and SelectionNotify steps.
11586 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11587 (x_convert_selection): New function.
11588 (x_handle_selection_event): Simplify.
11589 (x_get_foreign_selection): Don't ignore incoming requests while
11590 waiting for an answer; this will fail when we implement
11591 SAVE_TARGETS, and seems unnecessary anyway.
11592 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11593 (Vx_sent_selection_functions): Doc fix.
11595 2011-05-26 Leo Liu <sdl.web@gmail.com>
11597 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11599 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11601 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11603 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11604 for fringe update if it has periodic bitmap.
11605 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11606 and fringe_bitmap_periodic_p.
11608 * fringe.c (get_fringe_bitmap_data): New function.
11609 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11610 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11611 row. Mark glyph row for fringe update if periodicity changed.
11613 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11614 for fringe update unless it has periodic bitmap.
11616 2011-05-25 Kenichi Handa <handa@m17n.org>
11618 * xdisp.c (get_next_display_element): Set correct it->face_id for
11619 a static composition.
11621 2011-05-24 Leo Liu <sdl.web@gmail.com>
11624 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11626 * fns.c (crypto_hash_function, Fsha1): New function.
11627 (Fmd5): Use crypto_hash_function.
11628 (syms_of_fns): Add Ssha1.
11630 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11632 * gnutls.c: Remove unused macros.
11633 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11634 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11635 Remove macros that are defined and never used.
11636 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11638 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11640 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11641 (Fx_get_selection_internal): Minor cleanup.
11642 (Fx_own_selection_internal): Rename arguments for consistency with
11645 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11647 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11649 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11651 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11653 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11655 * dispnew.c (scrolling_window): Don't exclude the case that the
11656 last enabled row in the desired matrix touches the bottom boundary.
11658 2011-05-21 Glenn Morris <rgm@gnu.org>
11660 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11661 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11662 and add some more files.
11664 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11666 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11667 report_file_error introduced by the change from 2011-05-07.
11669 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11671 * systime.h (Time): Define only if emacs is defined.
11672 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11673 where the include path doesn't have X11/X.h by default. See
11674 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11676 2011-05-20 Kenichi Handa <handa@m17n.org>
11678 * composite.c (find_automatic_composition): Fix previous change.
11680 2011-05-20 Glenn Morris <rgm@gnu.org>
11682 * lisp.mk: New file, split from Makefile.in.
11683 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11684 (shortlisp): Remove.
11685 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11687 2011-05-19 Glenn Morris <rgm@gnu.org>
11689 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11690 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11691 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11692 (lisp): Set the order to that of loadup.el.
11693 (shortlisp): Make it a copy of $lisp.
11694 (SOME_MACHINE_LISP): Remove.
11695 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11696 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11698 2011-05-18 Kenichi Handa <handa@m17n.org>
11700 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11701 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11702 (find_automatic_composition): Mostly rewrite for efficiency.
11704 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11706 * makefile.w32-in: Update dependencies.
11708 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11710 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11711 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11713 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11715 Fix some integer overflow issues, such as string length overflow.
11717 * insdel.c (count_size_as_multibyte): Check for string overflow.
11719 * character.c (lisp_string_width): Check for string overflow.
11720 Use EMACS_INT, not int, for string indexes and lengths; in
11721 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11722 the resulting string length overflows an EMACS_INT; instead,
11723 report a string overflow if no precision given. When checking for
11724 precision exhaustion, use a check that cannot possibly have
11725 integer overflow. (Bug#8675)
11726 * character.h (lisp_string_width): Adjust to new signature.
11728 * alloc.c (string_overflow): New function.
11729 (Fmake_string): Use it. This doesn't change behavior, but saves
11730 a few bytes and will simplify future changes.
11731 * character.c (string_escape_byte8): Likewise.
11732 * lisp.h (string_overflow): New decl.
11734 Fixups, following up to the user-interface timestamp change.
11735 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11736 for UI timestamps, instead of unsigned long.
11737 * msdos.c (mouse_get_pos): Likewise.
11738 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11739 * w32gui.h (Time): Define by including "systime.h" rather than by
11740 declaring it ourselves. (Bug#8664)
11742 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11743 * image.c (clear_image_cache): Likewise.
11745 * term.c (term_mouse_position): Don't assume time_t wraparound.
11747 Be more systematic about user-interface timestamps.
11748 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11749 and sometimes 'EMACS_UINT', to represent these timestamps.
11750 This change causes it to use 'Time' uniformly, as that's what X uses.
11751 This makes the code easier to follow, and makes it easier to catch
11752 integer overflow bugs such as Bug#8664.
11753 * frame.c (Fmouse_position, Fmouse_pixel_position):
11754 Use Time, not unsigned long, for user-interface timestamps.
11755 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11756 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11757 * keyboard.h (last_event_timestamp): Likewise.
11758 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11759 * menu.h (xmenu_show): Likewise.
11760 * term.c (term_mouse_position): Likewise.
11761 * termhooks.h (struct input_event.timestamp): Likewise.
11762 (struct terminal.mouse_position_hook): Likewise.
11763 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11764 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11765 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11766 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11767 what it was before.
11768 * menu.h, termhooks.h: Include "systime.h", for Time.
11770 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11771 Don't assume that the difference between two unsigned long values
11772 can fit into an integer. At this point, we know button_down_time
11773 <= event->timestamp, so the difference must be nonnegative, so
11774 there's no need to cast the result if double-click-time is
11775 nonnegative, as it should be; check that it's nonnegative, just in
11776 case. This bug is triggered when events are more than 2**31 ms
11777 apart (about 25 days). (Bug#8664)
11779 * xselect.c (last_event_timestamp): Remove duplicate decl.
11780 (x_own_selection): Remove needless cast to unsigned long.
11782 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11783 that always fit in int. Use a sentinel instead of a counter, to
11784 avoid a temp and to allay GCC's concerns about possible int overflow.
11785 * frame.h (struct frame): Use int for menu_bar_items_used
11786 instead of EMACS_INT, since it always fits in int.
11788 * menu.c (grow_menu_items): Check for int overflow.
11790 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11792 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11793 Before, the code was not consistent. These values cannot exceed
11794 2**31 - 1 so there's no need to make them unsigned.
11795 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11796 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11797 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11799 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11801 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11802 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11803 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11804 presumably because the widths might not match.
11806 * window.c (size_window): Avoid needless test at loop start.
11808 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11810 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11812 2011-05-12 Drew Adams <drew.adams@oracle.com>
11814 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11816 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11818 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11819 `width' to `bar_area_x' and `bar_area_width', respectively.
11820 (x_scroll_run): Take account of fringe background extension.
11822 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11823 Rename local vars `left' and `width' to `bar_area_x' and
11824 `bar_area_width', respectively.
11825 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11826 background extension.
11828 2011-05-10 Jim Meyering <meyering@redhat.com>
11830 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11832 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11834 * image.c (Finit_image_library): Return t for built-in image types,
11835 like pbm and xbm. (Bug#8640)
11837 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11839 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11841 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11843 * w32console.c (Fset_screen_color): Doc fix.
11844 (Fget_screen_color): New function.
11845 (syms_of_ntterm): Defsubr it.
11847 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11848 unlink the temporary file if Fcall_process didn't create it in the
11850 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11851 child process will be redirected to a file specified with `:file'.
11852 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11853 cue to call_process_cleanup not to close that handle.
11855 2011-05-07 Ben Key <bkey76@gmail.com>
11857 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11858 one of two shell specific rules, either bootstrap-temacs-CMD or
11859 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11860 to the previous implementation of the bootstrap-temacs rule.
11861 The bootstrap-temacs-CMD rule is similar to the previous
11862 implementation of the bootstrap-temacs rule except that it
11863 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11866 These changes, along with some changes to nt/configure.bat,
11867 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11868 earlier fix to add support for --cflags and --ldflags options
11869 that include quotes so that it works whether make uses cmd or
11872 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11874 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11875 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11877 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11878 a string. Handle both cases.
11879 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11880 (Fdbus_register_method): Use Qinvalid_function.
11882 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11884 * makefile.w32-in: Update dependencies.
11885 (LISP_H): Add inttypes.h and stdin.h.
11886 (PROCESS_H): Add unistd.h.
11888 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11890 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11891 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11893 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11895 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11897 * term.c (vfatal): Remove stray call to va_end.
11898 It's not needed and the C Standard doesn't allow it here anyway.
11900 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11901 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11903 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11906 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11908 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11910 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11912 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11914 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11916 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11917 * charset.c (Fdefine_charset_internal): Don't initialize
11918 charset.code_space[15]. The value was garbage, on hosts with
11919 32-bit int (Bug#8600).
11921 * lread.c (read_integer): Be more consistent with string-to-number.
11922 Use string_to_number to do the actual conversion; this avoids
11923 rounding errors and fixes some other screwups. Without this fix,
11924 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11925 (digit_to_number): Move earlier, for benefit of read_integer.
11926 Return -1 if the digit is out of range for the base, -2 if it is
11927 not a digit in any supported base. (Bug#8602)
11929 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11931 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11932 to match comment at start of function. This also removes a
11933 GCC warning about overflow in a 32+64-bit port.
11935 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11937 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11938 Reported by Stefan Monnier in
11939 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11940 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11941 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11943 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11944 (EMACS_UINTPTR): Likewise, with uintptr_t.
11946 * lisp.h: Prefer 64-bit EMACS_INT if available.
11947 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11948 on 32-bit hosts that have 64-bit int, so that they can access
11950 However, temporarily disable this change unless the temporary
11951 symbol WIDE_EMACS_INT is defined.
11953 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11955 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11956 This removes an assumption that EMACS_INT and long are the same
11957 width as pointers. The assumption is true for Emacs porting targets
11958 now, but we want to make other targets possible.
11959 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11960 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11961 In the rest of the code, change types of integers that hold casted
11962 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11963 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11964 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11965 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11966 No need to cast type when ORing.
11967 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11968 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11969 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11970 assume EMACS_INT is the same width as char *.
11971 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11972 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11973 Remove no-longer-needed casts.
11974 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11975 (xg_tool_bar_help_callback, xg_make_tool_item):
11976 Use EMACS_INTPTR to hold an integer
11977 that will be cast to void *; this can avoid a GCC warning
11978 if EMACS_INT is not the same width as void *.
11979 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11980 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11981 (current_message_1, set_message_1):
11982 Use a local to convert to proper width without a cast.
11983 * xmenu.c (dialog_selection_callback): Likewise.
11985 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11986 Also, don't assume VALBITS / RAND_BITS is less than 5,
11987 and don't rely on undefined behavior when shifting a 1 left into
11989 * lisp.h (get_random): Change signature to match.
11991 * lread.c (hash_string): Use size_t, not int, for hash computation.
11992 Normally we prefer signed values; but hashing is special, because
11993 it's better to use unsigned division on hash table sizes so that
11994 the remainder is nonnegative. Also, size_t is the natural width
11995 for hashing into memory. The previous code used 'int', which doesn't
11996 retain enough info to hash well into very large tables.
11997 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11999 * dbusbind.c: Don't possibly lose pointer info when converting.
12000 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12001 Use XPNTR rather than XHASH, so that the high-order bits of
12002 the pointer aren't lost when converting through void *.
12004 * eval.c (Fautoload): Don't double-shift a pointer.
12006 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12008 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12010 * gnutls.c (DEF_GNUTLS_FN):
12011 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12013 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12015 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12018 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12020 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12021 New version that can reserve upto 2GB of heap space.
12023 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12025 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12027 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12029 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12030 `gnutls_certificate_set_x509_key_file'.
12032 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12034 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12035 Update dependencies.
12037 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12039 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12040 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12041 Remove unused parameter `fildes'.
12042 * process.c (read_process_output, send_process): Don't pass it.
12044 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12046 Fix previous change: the library cache is defined in w32.c.
12047 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12048 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12050 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12052 Implement dynamic loading of GnuTLS on Windows.
12054 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12055 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12056 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12059 * gnutls.c (Qgnutls_dll): Define.
12060 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12061 (gnutls_*): Declare function pointers.
12062 (init_gnutls_functions): New function to initialize function pointers.
12063 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)

12065 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12066 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12067 (emacs_gnutls_write, emacs_gnutls_read)
12068 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12069 (Fgnutls_available_p): New function.
12070 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12071 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.

12074 * image.c: Include w32.h.
12075 (Vimage_type_cache): Delete.
12076 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12077 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12078 (w32_delayed_load): Move to w32.c.
12080 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12082 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12083 (w32_delayed_load): Move from image.c. When loading a library, record
12084 its filename in the :loaded-from property of the library id.
12085 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12086 Initialize and staticpro them.
12087 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12089 * process.c: Include lisp.h before w32.h, not after.
12090 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12091 instead of gnutls_record_check_pending.
12093 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12095 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12097 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12098 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12101 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12103 * xterm.c (x_set_frame_alpha): Do not set property on anything

12124 * callproc.c: Indentation fixup.
12126 * sysdep.c (wait_for_termination_1): Make static.
12127 (wait_for_termination, interruptible_wait_for_termination):
12128 Move after wait_for_termination_1.
12130 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12132 * sysdep.c (interruptible_wait_for_termination): New function
12133 which is like wait_for_termination, but allows keyboard
12136 * callproc.c (Fcall_process): Add (:file "file") as an option for
12138 (Fcall_process_region): Ditto.
12140 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12142 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12143 rather than `XVECTOR (FOO)->size'.
12145 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12146 inttypes.h, as a gnulib replacement is used if it not available in
12149 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12151 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12152 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12153 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12155 * coding.c (coding_alloc_by_realloc): Error out if destination
12156 will grow beyond MOST_POSITIVE_FIXNUM.
12157 (decode_coding_emacs_mule): Abort if there isn't enough place in

12170 * window.c (window_scroll_line_based): Use a marker instead of
12171 simple variables to record original value of point. (Bug#7952)
12173 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12174 produced by %s or %c overflows available buffer space. (Bug#8545)
12176 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12178 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12179 (SIZE_MAX): Move defn after all includes, as they might #define it.
12181 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12183 * w32.c (init_environment): Warn about defaulting HOME to C:\.

12207 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12209 * makefile.w32-in: Update dependencies.
12211 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12213 Improve `doprnt' and its usage. (Bug#8545)
12214 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12215 `format_end'. Remove support for %l as a conversion specifier.
12216 Don't use xrealloc. Improve diagnostics when the %l size modifier
12217 is used. Update the commentary.
12219 * eval.c (verror): Simplify calculation of size_t.
12221 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12224 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12226 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12229 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12231 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12232 This makes this file independent of the recent pseudovector change.
12234 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12236 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12238 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12239 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12240 Remove unused local.
12241 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12243 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12244 GCC 4.6.0 optimizes based on type-based alias analysis.
12245 For example, if b is of type struct buffer * and v of type struct
12246 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12247 != &v->size, and therefore "v->size = 1; b->size = 2; return
12248 v->size;" must therefore return 1. This assumption is incorrect
12249 for Emacs, since it type-puns struct Lisp_Vector * with many other
12250 types. To fix this problem, this patch adds a new type struct
12251 vectorlike_header that documents the constraints on layout of vectors
12252 and pseudovectors, and helps optimizing compilers not get fooled
12253 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12254 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12255 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12257 (XSETPVECTYPE): Rewrite in terms of new macro.
12258 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12259 This is a bit clearer, and further avoids the possibility of
12260 undesirable aliasing.
12261 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12262 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12263 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12264 since Lisp_Subr is a special case (no "next" field).
12265 (ASIZE): Now uses header.size rather than size.
12266 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12267 to avoid the hassle of writing XVECTOR (foo)->header.size.
12268 (struct vectorlike_header): New type.
12269 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12270 object, to help avoid aliasing.
12271 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12272 (SUBRP): Likewise, since Lisp_Subr is a special case.
12273 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12274 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12275 (struct Lisp_Hash_Table): Combine first two members into a single
12276 struct vectorlike_header member. All uses of "size" and "next" members
12277 changed to be "header.size" and "header.next".
12278 * buffer.h (struct buffer): Likewise.
12279 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12280 * frame.h (struct frame): Likewise.
12281 * process.h (struct Lisp_Process): Likewise.
12282 * termhooks.h (struct terminal): Likewise.
12283 * window.c (struct save_window_data, struct saved_window): Likewise.
12284 * window.h (struct window): Likewise.
12285 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12286 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12287 * buffer.c (init_buffer_once): Likewise.
12288 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12290 * process.c (Fformat_network_address): Use local var for size,
12293 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12295 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12296 * data.c (atof): Remove decl; no longer used or needed.
12297 (digit_to_number): Move to lread.c.
12298 (Fstring_to_number): Use new string_to_number function, to be
12299 consistent with how the Lisp reader treats infinities and NaNs.
12300 Do not assume that floating-point numbers represent EMACS_INT
12301 without losing information; this is not true on most 64-bit hosts.
12302 Avoid double-rounding errors, by insisting on integers when
12303 parsing non-base-10 numbers, as the documentation specifies.
12304 * lisp.h (string_to_number): New decl, replacing ...
12305 (isfloat_string): Remove.
12306 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12307 (read1): Do not accept +. and -. as integers; this
12308 appears to have been a coding error. Similarly, do not accept
12309 strings like +-1e0 as floating point numbers. Do not report
12310 overflow for integer overflows unless the base is not 10 which
12311 means we have no simple and reliable way to continue.
12312 Break out the floating-point parsing into a new
12313 function string_to_number, so that Fstring_to_number parses
12314 floating point numbers consistently with the Lisp reader.
12315 (digit_to_number): Move here from data.c. Make it static inline.
12316 (E_CHAR, EXP_INT): Remove, replacing with ...
12317 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12318 (string_to_number): New function, replacing isfloat_string.
12319 This function checks for valid syntax and produces the resulting
12320 Lisp float number too. Rework it so that string-to-number
12321 no longer mishandles examples like "1.0e+". Use strtoumax,
12322 so that overflow for non-base-10 numbers is reported only when
12323 there's no portable and simple way to convert to floating point.
12325 * textprop.c (set_text_properties_1): Rewrite for clarity,
12326 and to avoid GCC warning about integer overflow.
12328 * intervals.h (struct interval): Use EMACS_INT for members
12329 where EMACS_UINT might cause problems. See
12330 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12331 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12332 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12334 (offset_intervals): Tell GCC not to worry about length overflow
12335 when negating a negative length.
12337 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12338 (overrun_check_free): Likewise.
12340 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12341 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12344 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12345 (gnutls_make_error): Rename local to avoid shadowing.
12346 (gnutls_emacs_global_deinit): ifdef out; not used.
12347 (Fgnutls_boot): Use const for pointer to readonly storage.
12348 Comment out unused local. Fix pointer signedness problems.
12350 * lread.c (openp): Don't stuff size_t into an 'int'.
12351 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12352 about possible signed overflow.
12354 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12355 (GDK_KEY_g): Don't define if already defined.
12356 (xg_prepare_tooltip): Avoid pointer signedness problem.
12357 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12359 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12360 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12362 * xfns.c (Fx_window_property): Simplify a bit,
12363 to make a bit faster and to avoid GCC 4.6.0 warning.
12364 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12366 * fns.c (internal_equal): Don't assume size_t fits in int.
12368 * alloc.c (compact_small_strings): Tighten assertion a little.
12370 Replace pEd with more-general pI, and fix some printf arg casts.
12371 * lisp.h (pI): New macro, generalizing old pEd macro to other
12372 conversion specifiers. For example, use "...%"pI"d..." rather
12373 than "...%"pEd"...".
12374 (pEd): Remove. All uses replaced with similar uses of pI.
12375 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12376 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12377 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12378 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12379 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12380 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12381 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12383 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12384 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12385 * print.c (safe_debug_print, print_object): Likewise.
12386 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12388 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12389 avoiding the 0 flag, which is not portable.
12390 * process.c (Fmake_network_process): Use pI to avoid cast.
12391 * region-cache.c (pp_cache): Likewise.
12392 * xdisp.c (decode_mode_spec): Likewise.
12393 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12394 behavior on 64-bit hosts with printf arg.
12395 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12396 (x_stop_queuing_selection_requests): Likewise.
12397 (x_get_window_property): Don't truncate byte count to an 'int'
12400 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12401 here, since it parses constructs like leading '-' and spaces,
12402 which are not wanted; and it overflows with large numbers.
12403 Instead, simply match F[0-9]+, which is what is wanted anyway.
12405 * alloc.c: Remove unportable assumptions about struct layout.
12406 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12407 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12408 (allocate_vectorlike, make_pure_vector): Use the new macros,
12409 plus offsetof, to remove unportable assumptions about struct layout.
12410 These assumptions hold on all porting targets that I know of, but
12411 they are not guaranteed, they're easy to remove, and removing them
12412 makes further changes easier.
12414 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12415 This doesn't fix a bug but makes the code clearer.
12416 (string_overrun_cookie): Now const. Use initializers that
12417 don't formally overflow signed char, to avoid warnings.
12418 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12419 can cause Emacs to crash when string overrun checking is enabled.
12420 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12421 multiple of sizeof (EMACS_INT); it need not be, if
12422 alignof(EMACS_INT) < sizeof (EMACS_INT).
12423 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12425 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12427 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12429 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12431 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12432 supposed to be handshaking. (Bug#8556)
12433 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12435 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12437 * lisp.h (Qdebug): List symbol.
12438 * eval.c (Qdebug): Restore global linkage.

12440 (handle_user_signal): Break into debugger when debug-on-event
12441 matches the current signal symbol.
12443 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12445 * alloc.c (check_sblock, check_string_bytes)
12446 (check_string_free_list): Convert to standard C.
12448 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12450 * w32.c (emacs_gnutls_push): Fix typo.
12452 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12454 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12455 "cast to pointer from integer of different size".
12457 Improve doprnt and its use in verror. (Bug#8545)
12458 * doprnt.c (doprnt): Document the set of format control sequences
12459 supported by the function. Use SAFE_ALLOCA instead of always
12462 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12463 is one byte too soon. Don't use xrealloc; instead xfree and
12466 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12468 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12471 * gnutls.c: Renamed global_initialized to
12472 gnutls_global_initialized. Added internals for the
12473 :verify-hostname-error, :verify-error, and :verify-flags
12474 parameters of `gnutls-boot' and documented those parameters in the
12475 docstring. Start callback support.
12476 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12477 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12478 on error. Return error code.
12479 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12480 (emacs_gnutls_read): Likewise.
12481 (Fgnutls_boot): Return handshake error code.
12482 (emacs_gnutls_handle_error): New function.
12483 (wsaerror_to_errno): Likewise.

12494 buffered some data internally if no FDs are set for TLS
12497 * makefile.w32-in (OBJ2): Add gnutls.$(O).

12538 changes in globals.h immediately force recompilation.
12539 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12540 $(CURDIR)/s/ms-w32.h.
12541 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

12545 <char-direction-table>: Deleted.
12547 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12549 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12550 * doprnt.c: Include limits.h.
12551 (SIZE_MAX): New macro.
12552 (doprnt): Return a size_t value. 2nd arg is now size_t.
12553 Many local variables are now size_t instead of int or unsigned.
12554 Improve overflow protection. Support `l' modifier for integer
12555 conversions. Support %l conversion. Don't assume an EMACS_INT
12556 argument for integer conversions and for %c.
12558 * lisp.h (doprnt): Restore prototype.
12560 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12561 $(SRC)/character.h.
12563 * Makefile.in (base_obj): Add back doprnt.o.
12565 * deps.mk (doprnt.o): Add back prerequisites.
12566 (callint.o): Depend on character.h.
12568 * eval.c (internal_lisp_condition_case): Include the handler
12569 representation in the error message.
12570 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12571 when breaking from the loop.
12573 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12575 * callint.c (Fcall_interactively): When displaying error message
12576 about invalid control letter, pass the character's codepoint, not
12577 a pointer to its multibyte form. Improve display of the character
12578 in octal and display also its hex code.
12580 * character.c (char_string): Use %x to display the (unsigned)
12581 codepoint of an invalid character, to avoid displaying a bogus
12584 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12585 `error', not SYMBOL_NAME itself.
12587 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12588 character arguments to `error'.
12590 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12591 to `error' in error message about FINAL_CHAR argument. Make sure
12592 FINAL_CHAR is a character, and use %c when it is passed as
12593 argument to `error'.
12595 2011-04-23 Eli Zaretskii <eliz@gnu.org>

12656 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
12657 Define only if needed.
12659 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

12782 * nsfont.m: Fixed bugs in ns_get_family and
12783 ns_descriptor_to_entity that were caused by using free to
12784 deallocate memory blocks that were allocated by xmalloc (via
12785 xstrdup). This caused Emacs to crash when compiled with
12786 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12787 --enable-checking=xmallocoverrun). xfree is now used to
12788 deallocate these memory blocks.

12805 (emacs_read, emacs_write): Use it.
12806 * process.c (send_process): Adjust to the new signatures of
12807 emacs_write and emacs_gnutls_write. Do not attempt to store

13139 * buffer.c (buffer_count): Remove unused var.
13141 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

13143 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13144 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13145 exported only to the debugger.
13147 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
13148 * atimer.h (run_all_atimers): Remove; not exported.
13150 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13151 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13152 was inaccessible from Lisp.
13153 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13154 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13156 alloc.c: Import and export fewer symbols, and remove unused items.
13157 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13159 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13160 it's not optimized away by whole-program optimization.
13161 (message_enable_multibyte, free_misc): Remove.
13162 (catchlist, handlerlist, mark_backtrace):
13163 Declare only if BYTE_MARK_STACK.

13173 (mark_backtrace): Define only if BYTE_MARK_STACK.
13174 * xdisp.c (message_enable_multibyte): Now static.
13176 Declare Lisp_Object Q* variables to be 'static' if not exported.
13177 This makes it easier for human readers (and static analyzers)
13178 to see whether these variables are used from other modules.
13179 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

13189 Remove decls of unexported vars.
13190 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13192 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13194 Make Emacs functions such as Fatom 'static' by default.
13195 This makes it easier for human readers (and static analyzers)
13196 to see whether these functions can be called from other modules.
13197 DEFUN now defines a static function. To make the function external
13198 so that it can be used in other C modules, use the new macro DEFUE.

13204 Remove decls, since these functions are now static.
13205 (Funintern, Fget_internal_run_time): New decls, since these functions
13206 were already external.

13256 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13258 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init

13272 (overrun_check_free): Protoize.
13274 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13276 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13277 since callers should never pass a negative size.
13278 Change the signature to match that of plain 'read' and 'write'; see
13279 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13280 * lisp.h: Update prototypes of emacs_write and emacs_read.
13282 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13284 * xdisp.c (redisplay_window): Don't try to determine the character
13285 position of the scroll margin if the window start point w->startp
13286 is outside the buffer's accessible region. (Bug#8468)
13288 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13290 Fix write-region and its subroutines for buffers > 2GB.
13291 * fileio.c (a_write, e_write): Modify declaration of arguments and
13292 local variables to support buffers larger than 2GB.
13293 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13295 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13296 argument, local variables, and return value.
13298 * lisp.h: Update prototypes of emacs_write and emacs_read.
13300 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13302 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13304 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13306 Fix more problems found by GCC 4.6.0's static checks.
13308 * xdisp.c (vmessage): Use a better test for character truncation.
13310 * charset.c (load_charset_map): <, not <=, for optimization,
13311 and to avoid potential problems with integer overflow.
13312 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13313 * casetab.c (set_identity, shuffle): Likewise.
13314 * editfns.c (Fformat): Likewise.
13315 * syntax.c (skip_chars): Likewise.
13317 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13318 This also lets GCC 4.6.0 generate slightly better loop code.
13320 * callint.c (Fcall_interactively): <, not <=, for optimization.
13321 (Fcall_interactively): Count the number of arguments produced,
13322 not the number of arguments given. This is simpler and lets GCC
13323 4.6.0 generate slightly better code.
13325 * ftfont.c: Distingish more carefully between FcChar8 and char.
13326 The previous code passed unsigned char * to a functions like
13327 strlen and xstrcasecmp that expect char *, which does not
13328 conform to the C standard.
13329 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13330 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13331 char * when the C standard requires it.
13333 * keyboard.c (read_char): Remove unused var.
13335 * eval.c: Port to Windows vsnprintf (Bug#8435).
13336 Include <limits.h>.
13337 (SIZE_MAX): Define if the headers do not.
13338 (verror): Do not give up if vsnprintf returns a negative count.
13339 Instead, grow the buffer. This ports to Windows vsnprintf, which
13340 does not conform to C99. Problem reported by Eli Zaretskii.
13341 Also, simplify the allocation scheme, by avoiding the need for
13342 calling realloc, and removing the ALLOCATED variable.
13344 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13346 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13347 But keep the doprint source code for now, as we might revamp it
13348 and use it again (Bug#8435).
13349 * lisp.h (doprnt): Remove.
13350 * Makefile.in (base_obj): Remove doprnt.o.
13351 * deps.mk (doprnt.o): Remove.
13353 error: Print 32- and 64-bit integers portably (Bug#8435).
13354 Without this change, on typical 64-bit hosts error ("...%d...", N)
13355 was used to print both 32- and 64-bit integers N, which relied on
13356 undefined behavior.
13357 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13358 * lisp.h (error, verror): Mark as printf-like functions.
13359 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13360 Report overflow in size calculations when allocating printf buffer.
13361 Do not truncate output string at its first null byte.
13362 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13363 Truncate the output at a character boundary, since vsnprintf does not
13365 * charset.c (check_iso_charset_parameter): Convert internal
13366 character to string before calling 'error', since %c now has the
13368 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13369 overflow when computing char to be passed to 'error'. Do not
13370 pass Lisp_Object to 'error'; pass the integer instead.
13371 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13372 formatted with plain %d.
13374 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13376 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13378 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13380 * xterm.c (x_catch_errors): Remove duplicate declaration.
13382 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13384 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13386 2011-04-10 Jim Meyering <meyering@redhat.com>
13388 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13389 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13390 return ssize_t not "int", and use size_t as the buffer length.
13391 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13392 * gnutls.h: Update declarations.
13393 * process.c (read_process_output): Use ssize_t, to match.
13394 (send_process): Likewise.
13396 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13398 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13400 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13402 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13403 Use unsigned char, to match FcChar8 type definition.
13405 * xterm.c (handle_one_xevent):
13406 * xmenu.c (create_and_show_popup_menu):
13407 * xselect.c (x_decline_selection_request)
13408 (x_reply_selection_request): Avoid type-punned deref of X events.
13410 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13412 Fix some uses of `int' instead of EMACS_INT.
13413 * search.c (string_match_1, fast_string_match)
13414 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13415 (scan_buffer, find_next_newline_no_quit)
13416 (find_before_next_newline, search_command, Freplace_match)
13417 (Fmatch_data): Make some `int' variables be EMACS_INT.
13419 * xdisp.c (display_count_lines): 3rd argument and return value now
13420 EMACS_INT. All callers changed.
13421 (pint2hrstr): Last argument is now EMACS_INT.
13423 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13424 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

13436 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13437 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13439 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13440 (encode_invocation_designation): Last argument P_NCHARS is now
13442 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13443 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13445 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13448 * ccl.c (Fccl_execute_on_string): Declare some variables
13451 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13453 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13455 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13457 * process.c (Fformat_network_address): Doc fix.
13459 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13461 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13463 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13465 * keyboard.c (read_char): Call Lisp function help-form-show,
13466 instead of using internal_with_output_to_temp_buffer.
13467 (Qhelp_form_show): New var.
13468 (syms_of_keyboard): Use DEFSYM macro.
13470 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13477 (list_processes_1): Delete.
13479 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13481 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13483 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13485 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13487 Fix more problems found by GCC 4.6.0's static checks.
13489 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13491 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13493 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13495 * xdisp.c (vmessage): Mark as a printf-like function.
13497 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13499 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13501 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13502 printf-like functions.
13503 (tiff_load): Add casts to remove these marks before passing them
13504 to system-supplied API.
13506 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13508 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13509 This avoids several warnings with gcc -Wstrict-overflow.
13510 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13511 directly, rather than having caller test rule sign. This avoids
13512 some unnecessary tests.
13513 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13514 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13515 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13517 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13518 (xfont_open): Avoid unnecessary tests.
13520 * composite.c (composition_gstring_put_cache): Use unsigned integer.

13528 * composite.c (get_composition_id): Remove unused local vars,
13529 by using the new macro.
13531 * textprop.c (set_text_properties_1): Change while to do-while,
13532 since the condition is always true at first.
13534 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13535 (interval_deletion_adjustment): Return unsigned value.
13538 * process.c (list_processes_1, create_pty, read_process_output):
13539 (exec_sentinel): Remove vars that were set but not used.
13540 (create_pty): Remove unnecessary "volatile"s.
13541 (Fnetwork_interface_info): Avoid possibility of int overflow.
13542 (read_process_output): Do adaptive read buffering even if carryover.
13543 (read_process_output): Simplify nbytes computation if buffered.
13545 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.

13550 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13551 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13552 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13554 * print.c (print_error_message): Avoid int overflow.
13556 * font.c (font_list_entities): Redo for clarity,
13557 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

13572 (wordify): Omit three unnecessary tests.
13574 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

13577 * casefiddle.c (casify_region): Remove var that is set but not used.
13579 * dired.c (file_name_completion): Remove var that is set but not used.
13581 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13583 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13584 (Finsert_file_contents): Remove unnecessary code checking fd.
13586 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13587 Check for integer overflow on size calculations.
13589 * buffer.c (Fprevious_overlay_change): Remove var that is set
13592 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13593 Remove vars that are set but not used.
13594 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13595 (timer_check_2): Mark vars as initialized.
13597 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13599 * image.c (lookup_image): Remove var that is set but not used.
13600 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13602 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13603 that are set but not used.
13605 * xfns.c (make_invisible_cursor): Don't return garbage
13606 if XCreateBitmapFromData fails (Bug#8410).
13608 * xselect.c (x_get_local_selection, x_handle_property_notify):
13609 Remove vars that are set but not used.
13611 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13612 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13614 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13615 Remove var that is set but not used.
13616 (scroll_bar_windows_size): Now size_t, not int.
13617 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13618 Check for overflow.
13620 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13621 (map_tty_color) [!defined MSDOS]: Likewise.
13623 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13625 * coding.c: Remove vars that are set but not used.
13626 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13627 All callers changed.
13628 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13629 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13630 (decode_coding_charset): Remove vars that are set but not used.
13632 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13633 that is set but not used.
13635 * print.c (print_object): Remove var that is set but not used.
13637 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13638 The gnulib version avoids calling malloc in the usual case,
13639 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13640 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13641 * filelock.c (current_lock_owner): Likewise.
13642 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13643 * sysdep.c: Include allocator.h, careadlinkat.h.
13644 (emacs_no_realloc_allocator): New static constant.
13645 (emacs_readlink): New function.
13646 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13647 ../lib/careadlinkat.h.
13649 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13651 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13652 first non-nil return value).

13661 * xdisp.c (display_count_lines): Remove parameter `start',
13662 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13663 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13664 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13666 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13667 and thereabouts. All callers changed.
13668 (get_per_char_metric): Remove parameter `f', unused since
13669 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13671 2011-04-02 Jim Meyering <meyering@redhat.com>
13673 do not dereference NULL upon failed strdup
13674 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13675 (ns_get_family): Likewise.
13677 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13679 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13681 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13683 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13686 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13688 Add lexical binding.
13690 * window.c (Ftemp_output_buffer_show): New fun.
13691 (Fsave_window_excursion):
13692 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13694 * lread.c (lisp_file_lexically_bound_p): New function.
13695 (Fload): Bind Qlexical_binding.
13696 (readevalloop): Remove `evalfun' arg.
13697 Bind Qinternal_interpreter_environment.
13698 (Feval_buffer): Bind Qlexical_binding.
13699 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13701 (syms_of_lread): Declare `lexical-binding'.
13703 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13705 * keyboard.c (eval_dyn): New fun.
13706 (menu_item_eval_property): Use it.
13708 * image.c (parse_image_spec): Use Ffunctionp.
13710 * fns.c (concat, mapcar1): Accept byte-code-functions.
13712 * eval.c (Fsetq): Handle lexical vars.
13713 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13714 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13715 (FletX, Flet): Obey lexical binding.
13716 (Fcommandp): Handle closures.
13717 (Feval): New `lexical' arg.
13718 (eval_sub): New function extracted from Feval. Use it almost
13719 everywhere where Feval was used. Look up vars in lexical env.
13721 (Ffunctionp): Move from subr.el.
13722 (Ffuncall): Handle closures.
13723 (apply_lambda): Remove `eval_flags'.
13724 (funcall_lambda): Handle closures and new byte-code-functions.
13725 (Fspecial_variable_p): New function.
13726 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13727 but without exporting it to Lisp.
13729 * doc.c (Fdocumentation, store_function_docstring):
13730 * data.c (Finteractive_form): Handle closures.
13732 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13735 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13737 (exec_byte_code): New function extracted from Fbyte_code to handle new
13738 calling convention for byte-code-functions. Add new byte-codes.
13740 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13742 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13744 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13746 * xdisp.c (redisplay_internal): Fix prototype.
13748 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13750 * xdisp.c (SCROLL_LIMIT): New macro.
13751 (try_scrolling): Use it when setting scroll_limit.
13752 Limit scrolling to 100 screen lines.
13753 (redisplay_window): Even when falling back on "recentering",
13754 position point in the window according to scroll-conservatively,
13755 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13757 (try_scrolling): When point is above the window, allow searching
13758 as far as scroll_max, or one screenful, to compute vertical
13759 distance from PT to the scroll margin position. This prevents
13760 try_scrolling from unnecessarily failing when
13761 scroll-conservatively is set to a value slightly larger than the
13762 window height. Clean up the case of PT below the margin at bottom
13763 of window: scroll_max can no longer be INT_MAX. When aggressive
13764 scrolling is in use, don't let point enter the opposite scroll
13765 margin as result of the scroll.
13766 (syms_of_xdisp) <scroll-conservatively>: Document the
13767 threshold of 100 lines for never-recentering scrolling.
13769 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13771 * dispextern.h (move_it_by_lines):
13772 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

13774 (message_log_check_duplicate): Remove parameters `prev_bol' and
13775 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13776 (redisplay_internal): Remove parameter `preserve_echo_area',
13777 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13779 * indent.c (Fvertical_motion):
13780 * window.c (window_scroll_pixel_based, Frecenter):
13781 Don't pass `need_y_p' to `move_it_by_lines'.
13783 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13785 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13786 steal a few bits to be more compact.
13787 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13788 Remove unneeded casts.
13790 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13792 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13794 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13795 binding" message (bug#7967).
13797 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13799 Fix more problems found by GCC 4.6.0's static checks.
13801 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13802 Remove unused local var.
13804 * editfns.c (Fmessage_box): Remove unused local var.
13806 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13807 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13808 Omit unused local vars.
13809 * window.c (shrink_windows): Omit unused local var.
13810 * menu.c (digest_single_submenu): Omit unused local var.
13811 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13812 Omit unused local var.
13814 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13815 Don't assume string length fits in int.
13816 (keyremap_step, read_key_sequence): Use size_t for sizes.
13817 (read_key_sequence): Don't check last_real_key_start redundantly.
13819 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13820 instead of alloca (Bug#8344).
13822 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13823 (Fbacktrace_frame): Don't assume nframes fits in int.
13825 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13827 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13830 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13832 * cm.c (calccost): Turn while-do into do-while, for clarity.
13834 * keyboard.c (syms_of_keyboard): Use the same style as later
13835 in this function when indexing through an array. This also
13836 works around GCC bug 48267.
13838 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13840 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13842 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13843 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13845 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13846 This avoids undefined behavior on integer overflow, and is a bit
13847 more convenient anyway since it is compared to a size_t variable.
13849 Variadic C functions now count arguments with size_t, not int.
13850 This avoids an unnecessary limitation on 64-bit machines, which
13851 caused (substring ...) to crash on large vectors (Bug#8344).
13852 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13853 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13861 * fns.c (concat): Likewise.
13862 * frame.c (x_set_frame_parameters): Likewise.
13863 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13864 0 if not found, not -1. All callers changed.
13866 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13867 (stack_copy_size): Now size_t, not int.
13868 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13870 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13872 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13873 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13874 All callers changed.
13876 * lisp.h (multibyte_char_to_unibyte):
13877 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13878 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13889 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13890 don't set the hook to nil, but remove the offending function instead.
13891 (Qcommand_hook_internal): Remove, unused.
13892 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13893 Vcommand_hook_internal.
13895 * eval.c (enum run_hooks_condition): Remove.
13896 (funcall_nil, funcall_not): New functions.
13897 (run_hook_with_args): Call each function through a `funcall' argument.

13911 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13912 All callers changed.
13914 * w32.c (_wsa_errlist): Use braces for struct initializers.
13916 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13917 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

14063 * term.c (Fsuspend_tty, Fresume_tty):
14064 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14065 * window.c (temp_output_buffer_show):
14066 * insdel.c (signal_before_change):
14067 * frame.c (Fhandle_switch_frame):

14072 * callint.c (Fcall_interactively):
14073 * buffer.c (Fkill_all_local_variables):
14074 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14076 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14077 unconditionally since it does the check itself.
14079 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14081 Fix more problems found by GCC 4.5.2's static checks.
14083 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14084 the first time through the loop, since we know p0 < p1 then.
14085 This also avoids a gcc -Wstrict-overflow warning.
14087 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14088 leading to a memory leak, possible in functions like
14089 load_charset_map_from_file that can allocate an unbounded number
14090 of objects (Bug#8318).
14092 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14093 that could (at least in theory) be that large.
14095 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14096 This is less likely to overflow, and avoids undefined behavior if
14097 overflow does occur. All callers changed. Use strtoul to scan
14098 for the unsigned long integer.
14099 (pint2hrstr): Simplify and tune code slightly.
14100 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14115 * process.c (Fmake_network_process): Use socklen_t, not int,
14116 where POSIX says socklen_t is required in portable programs.
14117 This fixes a porting bug on hosts like 64-bit HP-UX, where
14118 socklen_t is wider than int (Bug#8277).
14119 (Fmake_network_process, server_accept_connection):
14120 (wait_reading_process_output, read_process_output):
14123 * process.c: Rename or move locals to avoid shadowing.

14133 Make tparam.h and terminfo.c consistent.
14134 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14135 Include tparam.h instead, since it declares them.
14136 * cm.h (PC): Remove extern decl; tparam.h now does this.
14137 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14138 * terminfo.c: Include tparam.h, to check interfaces.
14139 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14140 (tparam): Adjust signature to match interface in tparam.h;
14141 this removes some undefined behavior. Check that outstring and len
14142 are zero, which they always are with Emacs.
14143 * tparam.h (PC, BC, UP): New extern decls.
14145 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14146 (xftfont_open): Rename locals to avoid shadowing.

14163 (find_automatic_composition, composition_adjust_point): Likewise.
14164 (composition_update_it): Mark var as initialized.
14165 (find_automatic_composition): Mark vars as initialized,
14166 with a FIXME (Bug#8290).

14170 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14171 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14172 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14173 to avoid shadowing.
14175 * textprop.c (property_change_between_p): Remove; unused.
14177 * intervals.c (interval_start_pos): Now static.
14179 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14185 Fix pointer signedness.
14186 (alsa_choose_format): Remove unused local var.
14187 (wav_play): Initialize a variable to 0, to prevent undefined
14188 behavior (Bug#8278).
14190 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14192 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14194 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14195 clobbering (Bug#8298).
14196 * sysdep.c (sys_subshell): Likewise.
14197 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14199 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14200 This should get cleaned up, so that child_setup has the
14201 same signature on all platforms.
14203 * callproc.c (call_process_cleanup): Now static.
14204 (relocate_fd): Rename locals to avoid shadowing.
14206 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14208 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14209 not to be necessary, and produces flickering.
14211 2011-03-20 Glenn Morris <rgm@gnu.org>
14213 * config.in: Remove file.
14215 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14217 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14218 are now in src/globals.h.

14260 Define only if needed.
14262 * unexelf.c (unexec): Name an expression,
14263 to avoid gcc -Wbad-function-cast warning.
14264 Use a different way to cause a compilation error if anyone uses
14265 n rather than nn, a way that does not involve shadowing.
14266 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14268 * deps.mk (unexalpha.o): Remove; unused.
14270 New file unexec.h, the (simple) interface for unexec (Bug#8267).

14392 (WORDCHAR_P): Likewise. This one is never needed, but is used

14423 New macros, so that the caller can use some names other than
14424 gcpro1, gcpro2, etc.
14425 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14427 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14428 argument, for consistency with GCPRO2_VAR, etc: it is now the

14431 * dired.c (directory_files_internal, file_name_completion):
14432 Rename locals to avoid shadowing.
14434 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14435 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14436 dired.c's scmp function, had undefined behavior.
14437 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14438 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14439 * buffer.h: ... to here, because these macros use current_buffer,
14440 and the new implementation with inline functions needs to have
14441 current_buffer in scope now, rather than later when the macros
14443 (downcase, upcase1): New static inline functions.
14444 (DOWNCASE, UPCASE1): Reimplement using these functions.
14445 This avoids undefined behavior in expressions like
14446 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14447 from race conditions in accessing the global variables
14448 case_temp1 and case_temp2.

14486 * buffer.c (fix_overlays_before): Mark locals as initialized.
14487 (fix_start_end_in_overlays): Likewise. This function should be
14488 simplified by using pointers-to-pointers, but that's a different

14491 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14492 (report_overlay_modification): Rename locals to avoid shadowing.

14497 to suppress a gcc -Wclobbered warning that does not seem to be right.
14498 (MAXPATHLEN): Define only if needed.
14500 * process.c (serial_open, serial_configure): Move decls from here ...
14501 * systty.h: ... to here, so that they can be checked.
14503 * fns.c (get_random, seed_random): Move extern decls from here ...
14504 * lisp.h: ... to here, so that they can be checked.
14506 * sysdep.c (reset_io): Now static.
14507 (wait_for_termination_signal): Remove; unused.
14509 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

14514 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14515 (describe_map_tree):
14516 Rename locals to avoid shadowing.
14518 * keyboard.c: Declare functions static if they are not used elsewhere.

14860 -Wuninitialized does not deduce are never used uninitialized.
14861 (detect_coding_iso_2022): Initialize a local variable that might
14862 be used uninitialized. Leave a FIXME because it's not clear that
14863 this initialization is needed. (Bug#8211)
