38 * w32.c (init_environment): Change the default values of many
39 environment variables in dflt_envvars[] to NULL, to avoid pushing
40 them into environment when they were not already defined. Remove
41 the code that deletes site-lisp subdirectories from the default
42 value of EMACSLOADPATH, as it is no longer needed.
43 (check_windows_init_file): Now external, not static. Use
44 Vload_path as is, without adding anything, as this function is now
45 called when Vload_path is already set up.
47 * w32.h (check_windows_init_file): Add prototype.
49 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
50 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
51 compatibility with Posix platforms.
52 (main): Move the call to check_windows_init_file to here from
54 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
55 any, in the DEFALT argument into the root of the Emacs build or
56 installation tree, as appropriate.
58 * callproc.c (init_callproc_1): Call decode_env_path instead of
59 doing its equivalent by hand.
60 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
61 the code that sets Vexec_path run on MS-Windows.
63 * lread.c (init_lread): Add comments to #ifdef's.
65 * msdos.c (dos_set_window_size, IT_update_begin)

73 Now constants, not macros.
75 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
77 Remove unnecessary casts involving pointers.
78 These casts are no longer needed now that we assume C89 or later,
79 since they involve casting to or from void *.
80 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
81 (make_pure_float, make_pure_vector):
82 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

89 * xfns.c (x_real_positions, select_visual):
90 * xselect.c (x_stop_queuing_selection_requests)
91 (x_get_window_property, x_get_window_property_as_lisp_data):
92 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
93 Remove unnecessary pointer casts.
94 * alloc.c (record_xmalloc): New function.
95 * lisp.h (record_xmalloc): New decl.
96 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
97 more like a function. This is because the pointer cast is not
98 needed. All uses changed.
99 * print.c (print_string, print_error_message): Avoid length recalc.
101 Improve fix for macroexp crash with debugging (Bug#12118).
102 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
103 ARRAY_MARK_FLAG when checking subscripts, because ASET is
104 not supposed to be invoked from the garbage collector.
105 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
106 (gc_aset): New function, which is like ASET but can be
107 used in the garbage collector.
108 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

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

174 * composite.c (COMPOSITE_INLINE):
175 * dispnew.c (DISPEXTERN_INLINE):
176 * sysdep.c (SYSTIME_INLINE):
177 Define to EXTERN_INLINE, so that the corresponding functions
178 are compiled into code.
179 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
180 (INLINE_HEADER_END): New macros.
181 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

201 hard-coding the path separator.
203 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
205 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
206 This how ASET and AREF are supposed to work, and makes
207 it easier to think about future improvements. See
208 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
209 * charset.h (set_charset_attr): New function.
210 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
211 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

619 2012-07-27 Eli Zaretskii <eliz@gnu.org>
621 * alloc.c (listn): Fix the order the arguments are consed onto the
624 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
625 enumeration constants, as PURE and HEAP are too general, and clash
626 with other headers and sources, such as gmalloc.c and the
627 MS-Windows system headers. All users changed.
629 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
631 Revert last save_excursion_save and save_excursion_restore changes.
632 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

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

647 complains about the types in the unevaluated arm when the argument
648 is an integer literal.
649 (xgetint): Simplify expression.
650 * alloc.c (gdb_make_enums_visible): New constant. This ports to
651 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
652 Zaretskii in <http://bugs.gnu.org/12036#13>.
653 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
654 needed now that we have gdb_make_enums_visible.

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

713 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
714 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
715 not be usable in #if. This simplifies things.
717 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
719 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
721 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

724 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
725 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
726 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
727 Adjust to changes in lisp.h and emacs.c, by using
728 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
729 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
730 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
731 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
732 instead of gdb_valbits.
733 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
734 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
735 instead of gdb_array_mark_flag.
736 (xboolvector): Get size from $->size, not $->header.size.
737 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
738 (xreload, hook-run, hookpost-run): Remove.
739 * emacs.c: Include <verify.h>.
740 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
741 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
743 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
744 (gdb_USE_LSB_TAG): New enum constants.
745 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

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

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

766 add argument, tune behavior, and adjust all callers.
768 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
770 Use typedef for EMACS_INT, EMACS_UINT.
771 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
772 than macros. This simplifies debugging in the usual case, since
773 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
774 and it allows expressions involving EMACS_INT casts.
775 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
777 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

790 * buffer.c (Fkill_buffer): Adjust indirection counters when the
791 buffer is definitely dead. This should really fix an issue reported
792 by Christoph Scholtes again. (Bug#12007).
793 (init_buffer_once): Initialize indirection counters of
794 buffer_defaults and buffer_local_symbols (for sanity and safety).
796 2012-07-24 Eli Zaretskii <eliz@gnu.org>
798 * xdisp.c (init_iterator): Don't compute dimensions of truncation
799 and continuation glyphs on tooltip frames, leave them at zero.
800 Avoids continued lines in tooltips. (Bug#11832)
802 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

829 Swap buffer text indirection counters in Fbuffer_swap_text.
830 * buffer.c (Fbuffer_swap_text): Swap indirections too.
831 This avoids crash reported by Christoph Scholtes at
832 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
834 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
836 * nsmenu.m (Popdown_data): New struct.
837 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
839 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

859 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
861 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
862 as it's limited by the amount of memory, not by INT_MAX.
864 2012-07-21 Eli Zaretskii <eliz@gnu.org>
866 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
867 in special-event-map. See the discussion at

1590 * s/aix4-2.h (unix): Remove; no longer needed.
1592 EMACS_TIME simplification (Bug#11875).
1593 This replaces macros (which typically do not work in GDB)

1595 The functional style also makes code easier to read and maintain.
1596 * systime.h: Include <sys/time.h> on all hosts, not just if
1597 WINDOWSNT, since 'struct timeval' is needed in general.

1610 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1611 not functions. All uses rewritten to use the following, respectively:
1612 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1613 (add_emacs_time, sub_emacs_time): New functions.
1614 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1635 * nsterm.m: Include <ftoastr.h>.
1637 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1638 Prefer snprintf to strncpy.
1639 * nsterm.m (ns_term_init):
1640 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1641 * nsterm.m (ns_term_init):
1642 Avoid the need for strncpy, by using build_string or
1643 make_unibyte_string directly. Use dtoastr, not snprintf.
1644 * process.c (Fmake_network_process): Diagnose service names that
1645 are too long, rather than silently truncating them or creating
1646 non-null-terminated names.

1663 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1664 where argument type is known to be a Lisp_Cons.

1719 O_RDONLY already includes it).
1721 Stop ns builds setting the EMACSLOADPATH environment variable.
1722 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1723 Now it does not set EMACSLOADPATH, just returns the load-path string.

1725 * lread.c [HAVE_NS]: Include nsterm.h.
1726 (init_lread) [HAVE_NS]: Use ns_load_path.

1736 (ns_init_paths): Do not set EMACSPATH.

1796 Move marker debugging code under MARKER_DEBUG.
1797 * marker.c (MARKER_DEBUG): Move marker debugging code under
1798 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1799 for bootstrap with --enable-checking (~3x slowdown reported

1840 Remove unused local.
1841 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1842 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1843 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1844 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1845 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1846 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1847 Fix pointer signedness problem.
1848 * xfaces.c (FRAME_X_FONT_TABLE):
1849 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1851 2012-07-07 Glenn Morris <rgm@gnu.org>
1853 * lread.c (load_path_check): New function, split from init_lread.
1854 (init_lread): Reorganize. Motivation:
1855 If EMACSLOADPATH is set, check/warn about that rather than the
1856 defaults, which we are not going to use. Hence we can remove
1857 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1858 Don't warn if site-lisp directories are missing.
1859 If not installed, start from a blank load-path, since
1860 PATH_LOADSEARCH refers to the eventual installation directories.
1862 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1864 Support truncation and continuation glyphs on GUI frames, when
1865 fringes are disabled. (Bug#11832)
1866 * xdisp.c (init_iterator): Get dimensions of truncation and
1867 continuation glyphs even if on GUI frames. Adjust
1868 it->last_visible_x on GUI frames when the left or right fringes,
1869 or both, are absent.
1870 (start_display, move_it_in_display_line_to): Handle the case of a
1871 GUI frame without a fringe to display continuation or truncation
1873 (insert_left_trunc_glyphs): Support GUI frames: make sure
1874 truncation glyphs overwrite enough glyphs from the current line to
1875 have sufficient space in pixels.
1876 (display_line): Support truncation and continuation glyphs on GUI
1877 frames. If some spare pixels are left on the line after inserting
1878 the truncation glyphs, fill that space with a stretch glyph of a
1879 suitably computed width.
1881 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1882 produce_glyphs, to support GUI sessions.
1884 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1886 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1888 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1890 Do not require float-time's arg to fit in time_t (Bug#11825).
1891 This works better on hosts where time_t is unsigned, and where
1892 float-time is applied to the (negative) difference between two times.
1893 * editfns.c (decode_time_components): Last arg is now double *,
1894 not int *, and means to store all the result as a double, without
1895 worrying about whether the seconds part fits in time_t.
1896 All callers changed.
1897 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1898 All callers changed.
1899 (Ffloat_time): Do not fail merely because the specified time falls
1900 outside of time_t range.
1902 2012-07-07 Glenn Morris <rgm@gnu.org>
1904 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1905 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

1908 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1910 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1911 Update dependencies.
1913 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1915 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1917 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1918 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1919 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1920 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1921 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1922 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1924 * xfont.c (compare_font_names): Redo to omit the need for casts.
1926 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1928 * xfns.c (Fx_change_window_property): Doc fix.
1929 * w32fns.c (Fx_change_window_property): Doc fix.
1931 * w32fns.c (Fx_window_property): Accept the same arguments as the
1932 X Windows version. Doc fix.
1933 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1935 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1936 Eli Zaretskii <eliz@gnu.org>
1938 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1939 Windows-specific code from nt/config.nt moved here.
1940 Obsolete settings removed.
1942 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1944 * process.c: Avoid unnecessary calls to gettime.
1945 (wait_reading_process_output): Don't get the time of day
1946 when gobbling data immediately and not waiting, as there's no need
1947 for it in that case. This removes a FIXME.
1949 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1951 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1952 is defined (Bug#11768).
1954 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1956 Fix marker debugging code.
1957 * marker.c (byte_char_debug_check): Do not perform the check
1958 if buffer is not multibyte.
1959 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1960 Call byte_char_debug_check with correct arguments.
1962 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1964 Compile marker debugging code only if ENABLE_CHECKING is defined.
1965 * marker.c (byte_char_debug_check, count_markers):
1966 Use only if ENABLE_CHECKING is defined.
1967 (byte_debug_flag): Remove.
1968 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1969 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1971 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1973 Avoid code repetition in marker-related functions.
1974 * marker.c (attach_marker): New function.
1975 (Fset_marker, set_marker_restricted, set_marker_both)
1976 (set_marker_restricted_both): Use it.
1977 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1978 Consistently rename charno to charpos.
1979 (marker_position): Add eassert.
1980 (marker_byte_position): Convert to eassert.
1982 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1984 Simplify list operations in unchain_overlay and unchain_marker.

1988 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1990 Introduce fast path for the widely used marker operation.
1991 * alloc.c (build_marker): New function.
1992 * lisp.h (build_marker): New prototype.
1993 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1994 * composite.c (autocmp_chars): Likewise.
1995 * editfns.c (buildmark): Remove.
1996 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1997 (save_restriction_save): Use build_marker.
1998 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1999 * window.c (save_window_save): Likewise.
2001 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2003 Do not use Fdelete_overlay in delete_all_overlays
2004 to avoid redundant calls to unchain_overlay.
2005 * buffer.c (drop_overlay): New function.
2006 (delete_all_overlays, Fdelete_overlay): Use it.
2007 * minibuf.c (get_minibuffer): Fix comment.
2009 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2011 Port to OpenBSD 5.1 amd64.
2012 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2013 This is needed for OpenBSD, and should be harmless on all BSD systems.
2014 Also, include <sys/sysctl.h>, as it should be available on all
2015 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2016 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2017 use p_pid member, not kp_proc.pid.
2019 2012-07-06 Glenn Morris <rgm@gnu.org>
2021 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2023 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2025 More xmalloc and related cleanup.
2026 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2027 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2032 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2033 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2034 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2036 Omit needless casts involving void * pointers and allocation.
2037 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2038 as the former is more robust if P's type is changed.
2039 Prefer xzalloc to xmalloc + memset 0.
2040 Simplify malloc-or-realloc to realloc.
2041 Don't worry about xmalloc returning a null pointer.
2042 Prefer xstrdup to xmalloc + strcpy.
2043 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2045 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2046 alloca of a constant.
2048 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2050 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2051 hscroll is larger than the line width. Fixes long and futile
2052 looping inside extend_face_to_end_of_line (on a TTY) producing
2053 glyphs that are not needed and thrown away.
2055 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2057 * marker.c (set_marker_restricted_both): Simplify by using
2060 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2067 not defined (Bug#11768).
2068 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2069 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2070 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2071 followed by gtk_box_set_homogeneous (Bug#11768).
2072 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2073 (update_theme_scrollbar_width, xg_create_scroll_bar):
2074 Use gtk_scrollbar_new (Bug#11768).
2075 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2076 (is_box_type): New function (Bug#11768).
2077 (xg_tool_item_stale_p): Call is_box_type.
2078 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2079 with default display (Bug#11768).
2081 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2083 * xdisp.c (window_hscroll_limited): New function.
2084 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2085 coordinates when window's hscroll is set to insanely large
2088 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2090 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2091 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2093 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2096 * lisp.h (xzalloc): New prototype. Omit needless casts.
2097 * alloc.c (xzalloc): New function. Omit needless casts.

2149 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2151 * fileio.c (time_error_value): Check the right error number.
2152 Problem reported by Troels Nielsen in
2153 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2155 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2157 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2158 This should be fixed in a better way; see Eli Zaretskii in
2159 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2160 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2162 * fileio.c (time_error_value): Rename from special_mtime.
2163 The old name's problems were noted by Eli Zaretskii in
2164 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2166 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2167 This variable's comment says Emacs needs at least one GDB-visible
2168 symbol of type enum pvec_type, to work around GDB problems.
2169 The symbol's value doesn't matter.
2171 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2172 that causes compilation to fail on pre-C99 compilers.
2174 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2176 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2177 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2179 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2181 * buffer.c (init_buffer_once): Fix initialization of
2182 headers for buffer_defaults and buffer_local_symbols.
2183 Reported by Juanma Barranquero <lekktu@gmail.com>.
2185 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2187 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2188 * lisp.h (enum pvec_type): Use fewer bits.
2189 (PSEUDOVECTOR_SIZE_BITS): New constant.
2190 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2191 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2192 change in pvec_type.
2193 (PSEUDOVECTOR_TYPEP): New macro.
2194 (TYPED_PSEUDOVECTORP): Use it.
2195 * fns.c (internal_equal): Adapt code to extract pvectype.
2196 * emacs.c (gdb_pvec_type): Update type.
2197 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2198 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2199 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2200 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2201 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2202 abusing vector->header.next.nbytes.
2203 (live_vector_p): Use PVEC_TYPE.
2204 (mark_object): Adapt code to extract pvectype. Use switch.
2206 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2208 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2209 Tighten new eassert a bit.
2211 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2213 Fix compilation with --enable-gcc-warnings and -O1
2215 * doprnt.c (doprnt): Change type of tem to int, initialize
2216 to avoid compiler warning. Add eassert.
2217 * search.c (simple_search): Initialize match_byte to avoid
2218 compiler warning. Add eassert.
2220 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2222 Avoid weird behavior with large horizontal scrolls.
2223 Without this change, for example, large hscroll values would
2224 mess up Emacs's display on Fedora 15 x86, presumably due to
2225 overflows in int calculations in the display code.
2226 Also, if buffers had long lines, Emacs would freeze.
2227 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2228 (set_window_hscroll): New function, containing the old guts of
2229 Fset_window_hscroll. Return the clipped value.
2230 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2231 This avoids the need to check against PTRDIFF_MAX.
2233 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2235 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2237 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2239 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2241 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2242 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2243 since GCC 4.4.6 issues a bogus warning for them.
2245 Fix bugs in file timestamp newness comparisons.
2246 * fileio.c (Ffile_newer_than_file_p):
2247 * lread.c (Fload): Use full timestamp resolution of files,
2248 not just the 1-second resolution, so that files that are only
2249 slightly newer still count as newer.
2250 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2251 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2253 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2255 * fileio.c: Improve handling of file time marker. (Bug#11852)
2256 (special_mtime): New function.
2257 (Finsert_file_contents, Fverify_visited_file_modtime):
2258 Use it to set special mtime values consistently.
2260 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2262 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2263 marker for non-existing file. (Bug#11852)
2265 2012-07-03 Glenn Morris <rgm@gnu.org>
2267 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2268 and did not make it into globals.h).
2270 2012-07-03 Tom Tromey <tromey@redhat.com>
2272 * window.c (Fset_window_margins, Fset_window_fringes)

2316 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2317 values which aren't power of 2.
2318 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2319 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2322 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2324 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2326 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2328 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2330 * alloc.c (allocate_vector_block): Remove redundant
2331 calls to mallopt if DOUG_LEA_MALLOC is defined.
2332 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2333 avoid calls to mallopt if zero_vector is returned.
2335 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2337 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2338 is enabled, avoid dereferencing NULL current_sblock if
2341 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2343 Cleanup basic buffer management.
2344 * buffer.h (struct buffer): Change layout to use generic vector
2345 marking code. Fix some comments. Change type of 'clip_changed'
2346 to bitfield. Remove unused #ifndef old.
2347 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2348 (GET_OVERLAYS_AT): Fix indentation.
2349 (for_each_per_buffer_object_at): New macro.
2350 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2353 * alloc.c (allocate_buffer): Adjust to match new layout of
2354 struct buffer. Fix comment.
2355 (mark_overlay): New function.

2357 Lisp area of struct buffer.
2358 (mark_object): Use it. Adjust marking of misc objects
2359 and related comments.
2361 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2363 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2364 wrapper that is not needed because the wrapped code is a no-op (zero
2365 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2366 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2368 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2370 * alloc.c (mark_buffer): Simplify. Remove prototype.
2371 (mark_object): Add comment. Reorganize marking of vector-like
2372 objects. Use CHECK_LIVE for all vector-like objects except buffers
2373 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2374 redundant calls to mark_vectorlike for bool vectors.
2376 2012-06-30 Glenn Morris <rgm@gnu.org>
2378 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2380 * epaths.in (PATH_SITELOADSEARCH): New.
2381 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2382 This is rather than relying on --enable-locallisppath elements
2383 having "site-lisp" in their names. (Bug#10208#25, 11658)
2385 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2387 * w32proc.c (sys_select): Accept and ignore one more argument.
2389 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2391 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2392 (pselect) [!MS_DOS]: Redirect to sys_select.
2394 * sysdep.c: Don't include dos.h and dosfns.h.
2396 * process.c (sys_select):
2397 * msdos.c (sys_select): Accept one more argument and ignore it.
2399 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2400 adapt data types and code to that.
2403 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2404 which clashes with the gnulib function of the same name.
2406 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2408 * font.c (font_style_to_value, font_style_symbolic)
2409 (font_prop_validate_style): Add type checks for values in
2412 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2414 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2417 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2419 * xdisp.c (try_window_id): Undo last change.
2421 * w32.c (getwd): Adjust commentary about startup_dir.
2422 (init_environment): Always call sys_access, even in non-MSVC
2423 builds. Don't chdir to the directory of the Emacs executable.
2424 This undoes code from 1997 which was justified by the need to
2425 "avoid conflicts when removing and renaming directories". But its
2426 downside was that every relative file name was being interpreted
2427 relative to the directory of the Emacs executable, which can never
2428 be TRT. In particular, it broke sys_access when called with
2429 relative file names.
2430 (sys_access): Map GetLastError to errno.
2432 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2434 * window.h (struct window): Change type of 'fringes_outside_margins'

2438 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2441 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

2444 Add QUIT to make the loop interruptible.
2446 2012-06-29 Glenn Morris <rgm@gnu.org>
2448 * charset.c (init_charset): Make lack of etc/charsets fatal.
2450 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2452 * editfns.c (region_limit): Fix type mismatch.
2454 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2456 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2457 undefined. Convert from xassert to eassert.
2458 * nsmenu.m: Convert from xassert to eassert.
2459 * nsterm.m: Likewise.
2461 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

2465 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2467 Avoid integer overflow on scroll-left and scroll-right.
2468 * window.c (HSCROLL_MAX): New macro.
2469 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

2474 * window.h (struct window): Change type of 'hscroll',
2475 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2476 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2477 Adjust users accordingly.
2478 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2479 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2480 from EMACS_INT to ptrdiff_t.
2481 (make_window): Omit redundant initialization.
2483 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2487 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

2556 * alloc.c (allocate_string): Omit intervals initialization.
2557 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2558 as in make_pure_string and make_pure_c_string.

2616 a better opportunity to optimize away calls to strlen when the
2617 function is called with compile-time constant argument.
2618 * image.c (imagemagick_error): Convert to build_string.
2619 * w32proc.c (sys_spawnve): Likewise.

2622 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2624 Use sprintf return value instead of invoking strlen on result.
2625 In the old days this wasn't portable, since some sprintf
2626 implementations returned char *. But they died out years ago and
2627 Emacs already assumes sprintf returns int.
2628 Similarly for float_to_string.
2629 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2636 * xfns.c (syms_of_xfns):
2637 Use sprintf or float_to_string result to avoid need to call strlen.
2638 * data.c (Fnumber_to_string):
2639 Use make_unibyte_string, since the string must be ASCII.
2640 * lisp.h, print.c (float_to_string): Now returns int length.
2641 * term.c (produce_glyphless_glyph):
2642 Use sprintf result rather than recomputing it.
2644 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

2677 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2680 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2682 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2683 instead of truncating it to 63 (admittedly a generous limit).
2685 * process.c: Fix spelling and caps in comments.
2687 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

2767 Privately reported by Herbert J. Skuhra.
2768 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2770 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

2800 in the logic of incrementing and decrementing the value of
2801 use_relocatable_buffers.
2803 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
2805 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2806 Privately reported by Herbert J. Skuhra.
2807 [__FreeBSD__]: Remove "*/" typo after "#include".
2808 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
2809 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2810 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2811 Don't assume EMACS_TIME and struct timeval are the same type.
2813 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2815 Support higher-resolution time stamps (Bug#9000).
2816 The time stamps are only nanosecond-resolution at the C level,
2817 since that's the best that any real-world system supports now.
2818 But they are picosecond-resolution at the Lisp level, as that's
2819 easy, and leaves room for future OS improvements.
2821 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2824 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2825 Don't get current time unless it's needed.
2827 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2828 now provides it if it's absent.
2829 (start_atimer): Port to higher-res time stamps.
2830 Check for time stamp overflow. Don't get current time more
2831 often than is needed.
2833 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2834 Include systime.h, not time.h.
2835 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2837 * dired.c: Include stat-time.h.
2838 (Ffile-attributes): File times now have higher resolution.
2840 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2841 (struct image): Timestamp now has higher resolution.
2843 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2844 has at least microseconds now. All uses removed.
2845 (update_frame, update_single_window, update_window, update_frame_1)
2846 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2848 * editfns.c (time_overflow): Now extern.
2849 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2851 (Fcurrent_time_zone): Accept and generate higher-resolution
2853 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2854 (decode_time_components, lisp_seconds_argument): New functions.
2855 (make_time): Now static.
2856 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2857 Report an error if the time is invalid, rather than having the caller
2860 * fileio.c: Include <stat-time.h>
2861 (Fcopy_file): Copy higher-resolution time stamps.
2862 Prefer to set the time stamp via a file descriptor if that works.
2863 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2864 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2865 (Fvisited_file_modtime, Fset_visited_file_modtime):
2866 Support higher-resolution time stamps.
2868 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2870 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2872 * image.c (prepare_image_for_display, clear_image_cache)
2873 (lookup_image): Port to higer-resolution time stamps.
2875 * keyboard.c (start_polling, bind_polling_period):
2876 Check for time stamp overflow.
2877 (read_char, kbd_buffer_get_event, timer_start_idle)
2878 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2879 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2880 Port to higher-resolution time stamps. Do not assume time_t is signed.
2881 (decode_timer): New function. Timers are now vectors of length 9,
2882 not 8, to accommodate the picosecond component.
2883 (timer_check_2): Use it.
2885 * nsterm.m (select_timeout, timeval_subtract): Remove.
2886 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2887 as they're a bit more accurate and handle overflow better.
2888 (ns_select): Change prototype to be compatible with pselect.
2889 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2890 * nsterm.h (ns_select): Adjust prototype.
2892 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2893 us-resolution time stamps.
2894 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2896 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2898 * lisp.h (time_overflow): New decl.
2899 (wait_reading_process_output): First arg is now intmax_t, not int,
2900 to accommodate larger waits.
2902 * process.h (struct Lisp_Process.read_output_delay):
2903 Now counts nanoseconds, not microseconds.
2904 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2906 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2907 (wait_reading_process_output):
2908 Port to ns-resolution time stamps.
2909 (Faccept_process_output, wait_reading_process_output):
2910 Check for time stamp overflow. Do not assume time_t is signed.
2911 (select_wrapper): Remove; we now use pselect.
2912 (Fprocess_attributes): Now generates ns-resolution time stamps.
2914 * sysdep.c: Include utimens.h. Don't include utime.h
2915 or worry about struct utimbuf; gnulib does that for us now.
2916 (gettimeofday): Remove; gnulib provides a substitute.
2917 (make_timeval): New function.
2918 (set_file_times): Now sets ns-resolution time stamps.
2919 New arg FD; all uses changed.
2920 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2921 (system_process_attributes):
2922 Now returns ns-resolution time stamp. All uses changed.
2923 Check for time stamp overflow.
2925 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2926 provides a substitute now.
2928 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2929 since it guarantees struct timespec.
2930 (EMACS_TIME): Now struct timespec, so that we can support
2931 ns-resolution time stamps.
2932 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2933 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2934 (EMACS_USECS): Remove.
2935 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2936 so multiply the arg by 1000 before storing it.
2937 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2939 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2940 Port to ns-resolution time stamps.
2941 (EMACS_TIME_NEG_P): Remove; replaced by....
2942 (EMACS_TIME_SIGN): New macro.
2943 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2944 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2945 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2946 (make_timeval, make_lisp_time, decode_time_components): New decls.
2947 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2948 that it mishandled time_t overflow. You can't compare by subtracting!
2949 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2950 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2952 * term.c: Include <sys/time.h>.
2953 (timeval_to_Time): New function, for proper overflow wraparound.
2954 (term_mouse_position, term_mouse_click): Use it.
2956 * undo.c (record_first_change): Support higher-resolution time stamps
2958 (Fprimitive_undo): Use them when restoring time stamps.
2960 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2961 (w32_get_internal_run_time):
2962 Port to higher-resolution Emacs time stamps.
2963 (ltime): Now accepts single 64-bit integer, as that's more convenient
2966 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2968 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2969 for compatibility with pselect. Support ns-resolution time stamps.
2971 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2973 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2974 Check for time stamp overflow, and support ns-resolution time stamps.
2976 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2977 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2978 (timeval_subtract): Remove; no longer needed.
2979 (XTflash, XTring_bell, x_wait_for_event):
2980 Port to ns-resolution time stamps. Don't assume time_t is signed.
2982 2012-06-22 Chong Yidong <cyd@gnu.org>

2986 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2988 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2989 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2990 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2991 staticidx goes up to 1597 out of 1600 = 0x640.)
2993 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2995 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2996 Otherwise, the umask might be mistakenly 0 while handling input signals.
2998 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3000 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3018 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3020 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3021 since tty frames can be explicitly named.
3022 (prepare_menu_bars): Likewise.
3024 * term.c (Ftty_top_frame): New function.
3026 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

3029 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3030 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3031 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3032 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3033 (METER_1, METER_2): Simplify.
3035 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

3039 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3041 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3042 gets killed during executing of this function (Bug#11665).
3043 Try to always return Qt when the buffer has been actually killed.
3044 (Vkill_buffer_query_functions): In doc-string say that functions
3045 run by this hook should not change the current buffer.
3047 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3049 Fix recently-introduced process.c problems found by static checking.
3050 * process.c (write_queue_push, write_queue_pop, send_process):

3067 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3069 * lisp.h (eassert): Assume C89 or later.
3070 This removes the need for CHECK.
3071 (CHECK): Remove. Its comments about always evaluating its
3072 argument were confusing, as 'eassert' typically does not evaluate
3075 * coding.c (produce_chars): Use ptrdiff_t, not int.
3077 * xterm.c (x_draw_underwave): Check for integer overflow.
3078 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3171 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
3172 If all the glyphs of the glyph row came from strings, and we have no
3173 cursor positioning clues, put the cursor on the first glyph of the

3262 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3263 code works fine either way, and efficiency is not a concern here,
3264 as the union type is for debugging, not for production.
3265 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3266 Use an inline function on all platforms when using the union type,
3267 since this is simpler and 'static inline' can be used portably
3269 (LISP_INITIALLY_ZERO): New macro.
3270 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3271 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3409 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3411 * doprnt.c (doprnt): Truncate multibyte char correctly.
3412 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3413 would mishandle a string argument "Xc" if X was a multibyte
3414 character of length 2: it would truncate after X's first byte
3415 rather than including all of X.
3417 2012-06-06 Chong Yidong <cyd@gnu.org>
3419 * buffer.c (word_wrap): Doc fix.

3468 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3469 Convert pctcpu and pctmem to Lisp float properly.
3470 Let the compiler fold better, as 100.0/0x8000 is exact.
3472 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3474 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3477 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3479 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3481 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3483 For a 'struct window', replace some Lisp_Object fields to
3484 bitfields where appropriate, remove unused fields.
3485 * window.h (struct window): Remove unused 'last_mark_x' and
3486 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3487 change it's type from Lisp_Object to bitfield.
3488 Change type of 'force_start', 'optional_new_start',
3489 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3490 fields from Lisp_Object to bitfield. Adjust users accordingly.
3492 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3494 Pacify gcc -Wdouble-precision when using Xaw.
3495 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3496 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3497 Use 'float' consistently, rather than 'float' in most places
3498 and 'double' in a couple of places.
3500 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3502 * xdisp.c (handle_stop): Detect whether we have overlay strings
3503 loaded by testing it->current.overlay_string_index to be
3504 non-negative, instead of checking whether n_overlay_strings is
3505 positive. (Bug#11587)
3507 2012-05-31 Chong Yidong <cyd@gnu.org>
3509 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3511 * doc.c (Fsubstitute_command_keys): Doc fix.
3513 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3515 * search.c (search_buffer): Remove calls to
3516 r_alloc_inhibit_buffer_relocation, as it is now called by
3517 maybe_unify_char, which was the cause of relocation of buffer text
3520 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3522 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3523 for the duration of call to load_charset, to avoid problems with
3524 callers of maybe_unify_char that access buffer text through C
3527 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3528 decrement the inhibition flag, instead of just setting or
3531 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3533 Remove obsolete '#define static' cruft.
3534 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3535 This #undef was "temporary" in 2000; it is no longer needed
3536 now that '#define static' has gone away.
3537 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3538 (gray_bitmap_bits): Remove; no longer needed.
3539 All uses replaced with definiens.
3540 * xterm.c: Include "bitmaps/gray.xbm".
3542 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3544 Clean up __executable_start, monstartup when --enable-profiling.
3545 The following changes affect the code only when profiling.
3546 * dispnew.c (__executable_start): Rename from safe_bcopy.
3547 Define only on platforms that need it.
3548 * emacs.c: Include <sys/gmon.h> when profiling.
3549 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

3551 (safe_bcopy): Remove decl; no longer has that name.
3552 (main): Coalesce #if into single bit of code, for simplicity.

3582 Do not create empty overlays with the evaporate property (Bug#9642).
3583 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3584 Bug#9642, but explicitly check that the buffer the overlay would
3585 be moved to is live and rearrange lines to make sure that errors
3586 will not put the overlay in an inconsistent state.
3587 (Fdelete_overlay): Cosmetics.
3589 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3591 * w32term.c (my_bring_window_to_top): New function.
3592 (x_raise_frame): Use handle returned by DeferWindowPos, which

3603 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3605 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3606 This avoids undefined behavior that might cause the eassert
3607 to not catch an out-of-range value.
3609 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3611 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3623 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3625 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3626 Only r_alloc_inhibit_buffer_relocation needed to be added;
3627 the others were already declared.
3629 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3630 before checking whether it's out of range. Put the check inside
3632 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3634 2012-05-27 Ken Brown <kbrown@cornell.edu>
3636 * callproc.c (Fcall_process): Restore a line that was accidentally
3637 commented out in the 2011-02-13 change (bug#11547).

3642 defined on ralloc.c.
3644 * buffer.c [REL_ALLOC]: Remove prototypes of
3645 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3646 they are now on lisp.h.
3648 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3650 * search.c (search_buffer): Use it to inhibit relocation of buffer
3651 text while re_search_2 is doing its job, because re_search_2 is
3652 passed C pointers to buffer text. (Bug#11519)
3654 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3657 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3658 state after an additional call to move_it_in_display_line_to, keep
3659 the values of it->max_ascent and it->max_descent found for the
3661 (pos_visible_p): Revert the comparison against bottom_y to what it
3662 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3665 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3667 Fix coding-related core dumps with gcc -ftrapv.
3668 The code was computing A - B, where A and B are pointers, and B is
3669 random garbage. This can lead to core dumps on platforms that
3670 have special pointer registers, and it also leads to core dumps on
3671 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3672 A - B only when B is initialized properly.
3673 * coding.c (coding_set_source, coding_set_destination): Return void.
3674 (coding_change_source, coding_change_destinations): New functions,
3675 with the old behaviors of coding_set_source and coding_set_destination.
3676 All callers that need an offset changed to use these new functions.

3680 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3682 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3684 Extend mouse support on W32 text-mode console.
3685 * xdisp.c (draw_row_with_mouse_face):
3686 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3688 * w32console.c: Include window.h.
3689 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3691 (initialize_w32_display): Initialize mouse-highlight data.
3693 * w32inevt.c: Include termchar.h and window.h.
3694 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3695 moves, call note_mouse_highlight. If help_echo changed, call
3696 gen_help_event to produce help-echo message in the echo area.
3697 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3700 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3702 * lread.c (read1): Simplify slightly to avoid an overflow warning
3703 with GCC 4.7.0 on x86-64.
3705 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3707 * bidi.c (bidi_mirror_char): Revert last change: an int is
3708 definitely wide enough here.

3720 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3722 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3723 (allocate_pseudovector):
3724 Use int, not EMACS_INT, where int is wide enough.
3725 (inhibit_garbage_collection, Fgarbage_collect):
3726 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3727 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3728 int might not be wide enough.
3729 (bidi_cache_search, bidi_cache_find, bidi_init_it)

3746 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3747 (validate_region): Omit unnecessary test for b <= e,
3748 since that's guaranteed by the previous test.

3750 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3751 (report_overlay_modification):

3753 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3755 after the EMACS_INT -> ptrdiff_t change.
3756 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3757 * buffer.h: Adjust decls to match defn changes elsewhere.

3762 not int, to avoid needless 32-bit limit on 64-bit hosts.
3763 (exec_byte_code): Use tighter memory-full test, one that checks
3764 for alloca overflow. Don't compute the address of the object just
3765 before an array, as that's not portable. Use EMACS_INT, not
3766 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3767 * callint.c (Fcall_interactively):
3768 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3781 (casify_object): Avoid integer overflow when overallocating buffer.

3785 * category.h (CATEGORYP): Don't assume arg is nonnegative.

3789 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3790 For CCL_MapSingle, check that content and value are in int range.

3793 (resolve_symbol_ccl_program): Check that vector header is in range.
3794 Always copy the vector, so that we can check its contents reliably
3795 now rather than having to recheck each instruction as it's being
3796 executed. Check that vector words fit in 'int'.
3797 (ccl_get_compiled_code, Fregister_ccl_program)

3825 Don't rely on undefined behavior with signed left shift overflow.
3826 Don't assume unsigned int fits into fixnum, or that fixnum fits
3827 into unsigned int. Don't require max_code to be a valid fixnum;
3828 that's not true for gb10830 4-byte on a 32-bit host. Allow
3829 invalid_code to be a cons, for the same reason. Require code_offset
3830 to be a character. Avoid int overflow if max_char is close
3832 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3833 this is intended anyway and avoids some undefined behavior.
3834 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3835 INDEX_TO_CODE_POINT, as that's what it expects.
3836 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3837 * charset.h (DECODE_CHAR): Return int, not unsigned;
3838 this is what was intended anyway, and it avoids undefined behavior.
3839 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3840 integer-overflow issues.
3841 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3842 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3843 where the argument is EMACS_INT, and this behavior is not intended.
3844 * chartab.c (Fmake_char_table, Fset_char_table_range)
3845 (uniprop_get_decoder, uniprop_get_encoder):
3846 Don't assume fixnum fits in int.
3847 * cmds.c (move_point): New function, that does the gist of
3848 Fforward_char and Fbackward_char, but does so while checking
3849 for integer overflow more accurately.
3850 (Fforward_char, Fbackward_char): Use it.

4458 doesn't matter here.
4459 (get_next_display_element, next_element_from_display_vector):
4460 Use int, not EMACS_INT, when int is wide enough.

4507 * xterm.h: Adjust decls to match defn changes elsewhere.
4508 (struct scroll_bar): Use struct vectorlike_header
4509 rather than rolling our own approximation.
4510 (SCROLL_BAR_VEC_SIZE): Remove; not used.
4512 2012-05-25 Glenn Morris <rgm@gnu.org>
4514 * lisp.mk (lisp): Update for more files being compiled now.
4516 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

4519 (read_pure): Remove var.
4520 (unreadpure): Remove function.
4521 (readevalloop): Don't call read_list with -1 flag.

4536 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4539 This directory predates autoconf and is no longer needed nowadays.
4540 Move its few remaining bits of functionality to where they're needed.
4541 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

4550 (EMACS_UINT): Define unconditionally now.
4551 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4552 (BITS_PER_EMACS_INT): New constants, replacing
4553 what used to be in config.h, but not useful in #if.
4554 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4555 define them any more.
4556 (VAL_MAX): New macro.
4558 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4559 BITS_PER_EMACS_INT, in #if.
4560 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4561 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4562 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4563 * s/ms-w32.h (DATA_START):
4564 Move here from removed file m/intel386.h.
4565 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4566 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4568 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4570 Assume C89 or later.

4580 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4581 * xterm.c (input_signal_count): Assume volatile works.
4583 2012-05-21 Ken Brown <kbrown@cornell.edu>
4585 * xgselect.c (xg_select): Fix first argument in call to 'select'
4588 2012-05-20 Ken Brown <kbrown@cornell.edu>
4590 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4591 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4593 2012-05-19 Ken Brown <kbrown@cornell.edu>
4595 * xfns.c (x_in_use): Remove `static' qualifier.
4596 * xterm.h (x_in_use): Declare.
4597 * xgselect.c: Include xterm.h.
4598 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4599 and `display_arg' (bug#9754).
4601 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4603 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4605 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4606 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4608 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4610 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4612 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4613 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4615 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4616 reference to image_cache->refcount.
4617 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4619 2012-05-17 Juri Linkov <juri@jurta.org>
4621 * search.c (Fword_search_regexp, Fword_search_backward)
4622 (Fword_search_forward, Fword_search_backward_lax)
4623 (Fword_search_forward_lax): Move functions to isearch.el
4624 (bug#10145, bug#11381).
4626 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4628 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4630 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4632 * lread.c (init_obarray): Declare Qt and Qnil as special.
4634 2012-05-14 Glenn Morris <rgm@gnu.org>
4636 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4637 Put "libexec" before "bin", for the sake of init_callproc_1.
4639 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4641 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4643 * unexaix.c: Port to more-recent AIX compilers.
4644 (report_error, report_error_1, make_hdr, copy_sym)
4645 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4646 Make arguments const char *, not char *, to avoid violations of C
4647 standard and to fix some AIX warnings reported by Gilles Pion.
4649 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4651 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4652 already have overlays loaded.
4653 (handle_single_display_spec): Before returning without displaying
4654 fringe bitmap, synchronize the bidi iterator with the main display
4655 iterator, by calling iterate_out_of_display_property.
4656 (iterate_out_of_display_property): Detect buffer iteration by
4657 testing that it->string is a Lisp string.
4658 (get_next_display_element): When the current object is exhausted,
4659 and there's something on it->stack, call set_iterator_to_next to
4660 proceed with what's on the stack, instead of returning zero.
4661 (set_iterator_to_next): If called at the end of a Lisp string,
4662 proceed to consider_string_end without incrementing string
4663 position. Don't increment display vector index past the end of
4664 the display vector. (Bug#11417)
4665 (pos_visible_p): Don't report a position visible when move_it_to
4666 stopped at the last line of window, which happens to be scanned
4667 backwards by the bidi iteration. (Bug#11464)
4669 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4671 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4672 and right-margin display specs even if the spec is invalid or we
4673 are on a TTY, and thus unable to display on the fringes.
4674 That's because the text with the property will not be displayed anyway,
4675 so we need to signal to the caller that this is a "replacing"
4676 display spec. This fixes display when the spec is invalid or we
4679 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4681 * unexaix.c (make_hdr): Fix typo in prototype.
4682 This bug broke the build on AIX. Problem reported by Gilles Pion.
4684 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4686 * keyboard.c (kbd_buffer_get_event): Read special events also in
4687 batch mode. (Bug#11415)
4689 2012-05-12 Glenn Morris <rgm@gnu.org>
4691 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4693 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4695 * lisp.mk (lisp): Add newcomment.elc.
4697 2012-05-12 Glenn Morris <rgm@gnu.org>
4699 * Makefile.in (MKDIR_P): New, set by configure.
4700 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4702 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4704 Remove unused function hourglass_started.
4705 * dispextern.h (hourglass_started):
4706 * w32fns.c (hourglass_started):
4707 * xdisp.c (hourglass_started): Remove.
4709 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4711 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4712 Update dependencies.
4714 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4716 * xgselect.c (xg_select): Put maxfds+1 into a var.
4717 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4719 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4721 2012-05-10 Dave Abrahams <dave@boostpro.com>
4723 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4724 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4726 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4728 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4729 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4730 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4731 Initialize xd_registered_buses.
4733 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4735 Untag more efficiently if USE_LSB_TAG.
4736 This is based on a proposal by YAMAMOTO Mitsuharu in
4737 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4738 For an admittedly artificial (nth 8000 longlist) benchmark on
4739 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4740 Emacs's overall text size by 1%.
4741 * lisp.h (XUNTAG): New macro.
4742 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4743 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4744 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4745 * eval.c (Fautoload):
4746 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4747 * frame.h (XFRAME): Use XUNTAG.
4749 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4750 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4751 Remove unportable assumptions about print widths of types like
4753 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4754 intptr_t when converting between pointer and integer, to avoid GCC
4755 warnings about wrong width.
4757 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4759 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4760 stack for each reader_thread, instead of defaulting to 8MB
4761 determined by the linker. This avoids failures in creating
4762 subprocesses on Windows 7, see the discussion in this thread:
4763 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4765 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4767 Fix up display of the *Minibuf-0* buffer in the mini window.
4768 * keyboard.c (read_char): Don't clear the echo area if there's no
4770 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4771 contents of *Minibuf-0*) if there's no message displayed in its stead.
4773 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4775 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4778 2012-05-06 Chong Yidong <cyd@gnu.org>
4780 * lisp.mk (lisp): Update.
4782 2012-05-05 Jim Meyering <meyering@redhat.com>
4784 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4786 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4788 * data.c (PUT_ERROR): New macro.
4789 (syms_of_data): Use it. Add new error type `user-error'.
4790 * undo.c (user_error): New function.
4791 (Fprimitive_undo): Use it.
4792 * print.c (print_error_message): Adjust print style for `user-error'.
4793 * keyboard.c (user_error): New function.
4794 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4796 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4798 Do not limit current-time-string to years 1000..9999.
4799 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4800 (Fcurrent_time_string): Support any year that is supported by the
4801 underlying localtime representation. Don't use asctime, as it
4802 has undefined behavior for years outside the range -999..9999.
4804 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4806 Fix race conditions involving setenv, gmtime, localtime, asctime.
4807 Without this fix, interrupts could mess up code that uses these
4808 nonreentrant functions, since setting TZ invalidates existing
4809 tm_zone or tzname values, and since most of these functions return
4810 pointers to static storage.
4811 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4812 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4813 Grow the critical sections to include not just invoking
4814 localtime/gmtime, but also accessing these functions' results
4815 including their tm_zone values if any, and any related TZ setting.
4816 (format_time_string): Last arg is now struct tm *, not struct tm **,
4817 so that the struct tm is saved in the critical section.
4818 All callers changed. Simplify allocation of initial buffer, partly
4819 motivated by the fact that memory allocation needs to be outside
4820 the critical section.
4822 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4824 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4825 with RESET_INTERVAL.
4827 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4828 Remove duplicated buffer name initialization.
4830 2012-05-02 Jim Meyering <jim@meyering.net>
4832 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4834 * xfns.c (x_window): Use xstrdup (Bug#11375).
4836 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4838 * xdisp.c (pos_visible_p): If already at a newline from the
4839 display string before the 'while' loop, don't walk back the glyphs
4840 from it3.glyph_row. Solves assertion violation when the display
4841 string begins with a newline (egg.el). (Bug#11367)
4843 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4845 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4848 2012-05-01 Glenn Morris <rgm@gnu.org>
4850 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4851 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4852 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4853 All were removed before 23.1.
4855 * dispnew.c: Remove HAVE_LIBNCURSES test;
4856 it is always true on relevant platforms.
4858 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4859 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4861 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4863 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4865 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4866 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4869 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4871 Do not avoid creating empty evaporating overlays (Bug#9642).
4872 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4873 That is, do not delete an evaporating overlay if it becomes
4874 empty after its bounds are adjusted to fit within its buffer.
4875 This fix caused other problems, and I'm reverting it until we get
4876 to the bottom of them.
4878 2012-04-27 Chong Yidong <cyd@gnu.org>
4880 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4882 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4884 * xdisp.c (pos_visible_p): If the window start position is beyond
4885 ZV, start the display from buffer beginning. Prevents assertion
4886 violation in init_iterator when the minibuffer window is scrolled
4889 * window.c (window_scroll_pixel_based): Likewise.
4891 2012-04-27 Chong Yidong <cyd@gnu.org>

4898 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4900 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4902 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4903 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4905 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4907 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4908 display element, check also the underlying string or buffer
4909 character. (Bug#11341)
4911 * w32menu.c: Include w32heap.h.
4912 (add_menu_item): If the call to AppendMenuW (via
4913 unicode_append_menu) fails, disable Unicode menus only if we are
4914 running on Windows 9X/Me.
4916 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4918 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4921 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4923 * keyboard.c (read_char): Don't wipe echo area for select window
4924 events: These might get delayed via `mouse-autoselect-window'

4930 manipulation of :loaded-from data.
4932 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4934 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4935 now a cons (bug#11311).
4937 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4939 Do not create empty overlays with the evaporate property (Bug#9642).
4940 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4941 if it becomes empty after its bounds are adjusted to fit within
4942 its buffer. Without this fix, in a nonempty buffer (let ((o
4943 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4944 yields an empty overlay that has the evaporate property, which is
4945 not supposed to happen.
4947 Fix minor GTK3 problems found by static checking.
4948 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

5062 * sysdep.c [__FreeBSD__]: Minor cleanups.
5063 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5064 Use Emacs indenting style more consistently. Avoid some casts.
5065 Use 'double' consistently rather than mixing 'float' and 'double'.

5085 (print_object): Check for cycles even when print-circle is nil and
5086 print-gensym is t, but only check print_depth if print-circle is nil.
5088 2012-04-20 Chong Yidong <cyd@gnu.org>
5090 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5091 set the status to "failed" and ensure that sentinel is run.

5146 New extern decls, to avoid calling undeclared functions.
5147 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5148 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5149 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

5166 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5167 Remove decls. This fixes an "It stinks!".
5169 * alloc.c (which_symbols): Fix alignment issue / type clash.
5171 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5173 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5194 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5196 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5219 2012-04-11 Daniel Colascione <dancol@dancol.org>
5221 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5222 against is gone. It's better to use vfork now so that when Cygwin
5223 gains a new, working vfork, we use it automatically (bug#10398).
5225 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5265 * gnutls.c (gnutls_log_function2i): Convenience log function.
5266 (emacs_gnutls_read): Use new log functions,
5267 `gnutls_handshakes_tried' process member, and
5268 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5269 attempts per process (connection).

5280 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5282 * xdisp.c (set_cursor_from_row): If the display string appears in
5283 the buffer at position that is closer to point than the position
5284 after the display string, display the cursor on the first glyph of
5285 the display string. Fixes cursor display when a 'display' text
5286 property immediately follows invisible text. (Bug#11094)
5288 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5290 composite.c: use 'double' consistently
5291 * composite.c (get_composition_id): Use 'double' consistently
5292 instead of converting 'float' to 'double' and vice versa; this is
5293 easier to understand and avoids a GCC warning.
5295 2012-04-09 Glenn Morris <rgm@gnu.org>
5297 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5298 preparation for dumping it with emacs. (Bug#4789)

5324 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5326 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5328 Fix typo that broke non-Windows builds.
5329 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5342 [!WINDOWSNT]: New macros.
5343 (init_libxml2_functions, libxml2_loaded_p): New functions.
5344 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5345 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5346 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5347 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5349 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5350 Call init_libxml2_functions before calling libxml2 functions.
5351 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5353 * emacs.c: Don't include libxml/parser.h.
5354 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5355 xmlCleanupParser directly.
5357 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5359 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5361 * indent.c (Fvertical_motion): If there is a display string at
5362 point, use it.vpos to compute how many lines to backtrack after
5363 move_it_to point. (Bug#11133)
5365 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5367 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5368 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5369 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5370 macros related to unification of CJK characters. For the details,
5371 see the discussion following the message here:
5372 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5374 2012-04-04 Chong Yidong <cyd@gnu.org>
5376 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5378 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5380 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5381 instead of alloca. (Bug#11138)
5383 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5385 * w32menu.c (is_simple_dialog): Properly check lisp types.
5388 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5390 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5391 position we get to after a call to move_it_to fails the
5392 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5393 only if we wind up in a string from display property. (Bug#11063)
5395 * window.c (Fdelete_other_windows_internal): Invalidate the row
5396 and column information about mouse highlight, so that redisplay
5397 restores it after reallocating the glyph matrices. (Bug#7464)
5399 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5400 string comes from a `display' text property, use the buffer
5401 position of that property as if we actually saw that position in
5403 (move_it_by_lines): Remove the assertion that
5404 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5405 violated when there's a before-string at the beginning of a line.
5408 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5410 * xdisp.c (append_space_for_newline): If the default face was
5411 remapped, use the remapped face for the appended newline.
5412 (extend_face_to_end_of_line): Use the remapped default face for
5413 extending the face to the end of the line.
5414 (display_line): Call extend_face_to_end_of_line when the default
5415 face was remapped. (Bug#11068)
5417 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5419 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5421 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5423 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5425 2012-03-27 Glenn Morris <rgm@gnu.org>
5427 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5430 2012-03-26 Kenichi Handa <handa@m17n.org>
5432 * dispextern.h (struct glyph): Fix previous change. Change the
5433 bit length of glyphless.ch to 25 (Bug#11082).
5435 2012-03-26 Chong Yidong <cyd@gnu.org>
5437 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5438 (command_loop_1): Use it; inhibit selection update for
5439 handle-select-window too (Bug#8996).
5441 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5443 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5445 2012-03-25 Kenichi Handa <handa@m17n.org>
5447 * dispextern.h (struct glyph): Change the bit length of
5448 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5450 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5452 * s/ms-w32.h (tzname): Include time.h before redirecting to
5453 _tzname. Fixes the MSVC build. (Bug#9960)
5455 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5457 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5460 * xterm.c (XTread_socket): Only modify handling_signal if
5461 !SYNC_INPUT. (Bug#11080)
5463 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5465 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5466 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5467 when fetching a multibyte character consumes more bytes than
5468 CHAR_BYTES returns, due to unification of CJK characters in
5469 string_char. (Bug#11073)
5471 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5473 * process.c (wait_reading_process_output): Handle pty disconnect
5474 by refraining from sending oneself a SIGCHLD (bug#10933).
5476 2012-03-22 Chong Yidong <cyd@gnu.org>
5478 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5480 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

5485 2012-03-21 Chong Yidong <cyd@gnu.org>
5487 * xfaces.c (Vface_remapping_alist): Doc fix.
5489 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5491 * w32proc.c (Fw32_set_console_codepage)
5492 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5495 2012-03-20 Chong Yidong <cyd@gnu.org>
5497 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5498 to reflect default non-nil value of redisplay-dont-pause.
5500 2012-03-19 Kenichi Handa <handa@m17n.org>
5502 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5503 it fit in a valid range (Bug#11003).
5505 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5507 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5508 that is not from display property, accept the row as a "cursor
5509 row" if one of the string's character has a non-nil `cursor'
5510 property. Fixes cursor positioning when there are newlines in
5511 overlay strings, e.g. in icomplete.el. (Bug#11035)
5513 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5515 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5517 2012-03-12 Chong Yidong <cyd@gnu.org>
5519 * eval.c (inhibit_lisp_code): Rename from
5520 inhibit_window_configuration_change_hook; move from window.c.
5522 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5523 * window.c (run_window_configuration_change_hook)
5524 (syms_of_window): Callers changed.
5526 2012-03-11 Chong Yidong <cyd@gnu.org>

5535 is visible (Bug#10955).
5537 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5539 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5541 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5543 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5544 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5547 2012-03-03 Glenn Morris <rgm@gnu.org>
5549 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5551 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5553 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5554 position past the first glyph_row that ends at ZV. (Bug#10902)
5555 (redisplay_window, next_element_from_string): Fix typos in
5557 (redisplay_window): Pass to move_it_vertically the margin in
5558 pixels, not in screen lines.
5560 2012-03-02 Glenn Morris <rgm@gnu.org>
5562 * buffer.c (buffer-list-update-hook): Doc fix.
5564 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5566 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5567 push_it before setting up the iterator for the first overlay
5568 string, even if we have an empty string loaded.
5569 (next_overlay_string): If there's an empty string on the iterator
5570 stack, pop the stack. (Bug#10903)
5572 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5574 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5575 Suggested by Stefan Monnier in
5576 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5577 * alloc.c (widen_to_Lisp_Object): New static function.
5578 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5579 and widening them to Lisp_Objects. This would work even if
5580 USE_LSB_TAG is defined and wide integers are used, which might
5581 happen in a future version of Emacs.
5583 2012-02-25 Chong Yidong <cyd@gnu.org>
5585 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5588 * xselect.c (Fx_selection_exists_p): Doc fix.
5589 (x_clipboard_manager_save_all): Print an informative message
5590 before saving to clipboard manager.
5592 2012-02-24 Chong Yidong <cyd@gnu.org>
5594 * keyboard.c (process_special_events): Handle all X selection
5595 requests in kbd_buffer, not just the next one (Bug#8869).
5597 2012-02-23 Chong Yidong <cyd@gnu.org>
5599 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5600 call when setting menu-bar-lines and tool-bar-lines parameters.
5601 (unwind_create_frame_1): New helper function.
5603 * window.c (inhibit_window_configuration_change_hook): New var.
5604 (run_window_configuration_change_hook): Obey it.
5605 (syms_of_window): Initialize it.
5607 2012-02-22 Chong Yidong <cyd@gnu.org>
5609 * xterm.c (x_draw_image_relief): Add missing type check for
5610 Vtool_bar_button_margin (Bug#10743).
5612 2012-02-21 Chong Yidong <cyd@gnu.org>
5614 * fileio.c (Vfile_name_handler_alist): Doc fix.
5616 * buffer.c (Fget_file_buffer): Protect against invalid file
5617 handler return value.
5619 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5621 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5622 when computing $valmask.
5624 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5625 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5626 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5627 It's useless in that case, and it can cause problems on hosts
5628 that allocate halves of EMACS_INT values separately.
5629 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5630 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5631 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5632 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5633 it avoids undefined behavior on hosts where shifting right by more
5634 than the word width has undefined behavior.
5636 2012-02-19 Chong Yidong <cyd@gnu.org>
5638 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5639 (Funhandled_file_name_directory, Ffile_name_as_directory)
5640 (Fdirectory_file_name, Fexpand_file_name)
5641 (Fsubstitute_in_file_name): Protect against invalid file handler
5642 return values (Bug#10845).
5644 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5646 * .gdbinit (pitx): Fix incorrect references to fields of the
5649 2012-02-17 Chong Yidong <cyd@gnu.org>
5651 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5653 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5655 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5656 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5658 2012-02-15 Chong Yidong <cyd@gnu.org>
5660 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5661 marked as special. Also, starting docstrings with * is obsolete.
5663 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5665 * gnutls.c (emacs_gnutls_write): Fix last change.
5667 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

5672 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5674 * keymap.c (Fsingle_key_description): Handle char ranges.
5676 2012-02-12 Chong Yidong <cyd@gnu.org>
5678 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5679 as that creates a dangerous corner case.
5681 * window.c (Fdelete_window_internal): Invalidate the mouse
5682 highlight (Bug#9904).
5684 2012-02-12 Glenn Morris <rgm@gnu.org>
5686 * xselect.c (Fx_own_selection_internal)
5687 (Fx_get_selection_internal, Fx_disown_selection_internal)
5688 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5689 * nsselect.m (Fx_own_selection_internal)
5690 (Fx_disown_selection_internal, Fx_selection_exists_p)
5691 (Fx_selection_owner_p, Fx_get_selection_internal):
5692 Sync docs and argument specs with the xselect.c versions.
5694 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5696 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5698 2012-02-11 Eli Zaretskii <eliz@gnu.org>

5701 argument list with xselect.c. (Bug#10783)
5703 * w16select.c (Fx_selection_exists_p): Sync doc string and
5704 argument list with xselect.c. (Bug#10783)

5714 2012-02-07 Chong Yidong <cyd@gnu.org>
5716 * buffer.c (Fbuffer_local_variables)
5717 (buffer_lisp_local_variables): Handle unbound vars correctly;
5718 don't let Qunbound leak into Lisp.
5720 2012-02-07 Glenn Morris <rgm@gnu.org>
5722 * image.c (Fimagemagick_types): Doc fix.
5724 * image.c (imagemagick-render-type): Change it from a lisp object
5725 to an integer. Move the doc here from the lisp manual.

5728 2012-02-06 Chong Yidong <cyd@gnu.org>
5730 * doc.c (store_function_docstring): Avoid applying docstring of
5731 alias to base function (Bug#2603).
5733 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5735 * .gdbinit (pp1, pv1): Remove redundant defines.
5738 2012-02-04 Chong Yidong <cyd@gnu.org>
5740 * nsterm.m: Declare a global (Bug#10694).
5742 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5744 * w32.c (get_emacs_configuration_options):
5745 Include --enable-checking, if specified, in the return value.
5747 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5749 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5750 after rounding frame sizes. (Bug#9723)
5752 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5754 * keyboard.c (adjust_point_for_property): Don't position point
5755 before BEGV. (Bug#10696)
5757 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5759 Handle overflow when computing char display width (Bug#9496).
5760 * character.c (char_width): Return EMACS_INT, not int.
5761 (char_width, c_string_width): Check for overflow when
5762 computing the width; this is possible now that individual
5763 characters can have unbounded width. Problem introduced
5764 by merge from Emacs 23 on 2012-01-19.
5766 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5768 * dbusbind.c (Fdbus_register_method): Mention the return value

5781 2012-02-02 Kenichi Handa <handa@m17n.org>
5783 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5784 0, do not call append_composite_glyph.
5786 2012-02-02 Kenichi Handa <handa@m17n.org>
5788 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5790 (x_produce_glyphs): If the component of a composition is a null
5791 string, set it->pixel_width to 1 to avoid zero-width glyph.
5793 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5795 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5796 first 2 arguments are identical. This makes inserting large
5797 output from a subprocess an order of magnitude faster on
5798 MS-Windows, where all sbrk'ed memory is always contiguous.
5800 2012-01-31 Glenn Morris <rgm@gnu.org>

5814 2012-01-28 Chong Yidong <cyd@gnu.org>
5816 * minibuf.c (syms_of_minibuf): Doc fix (Bug#10550).
5818 2012-01-26 Chong Yidong <cyd@gnu.org>

6417 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6418 is set, removing the need for VIRT_ADDRESS_VARIES.
6419 (PURE_P): Use a more-efficient implementation that needs just one
6420 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6421 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6422 to 4 (xorl, subq, cmpq, setbe).
6423 * alloc.c (pure): Always extern now, since that's the
6424 VIRT_ADDR_VARIES behavior.
6425 (PURE_POINTER_P): Use a single comparison, not two, for
6426 consistency with the new puresize.h.
6427 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6434 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6435 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6436 behave as if the cursor position were at the window margin.
6438 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6439 and the cursor position is out of bounds, behave as if the cursor
6440 position were at the window margin. (Bug#10075)
6442 2011-11-18 Chong Yidong <cyd@gnu.org>
6444 * window.c (Fwindow_combination_limit): Make first argument

6467 (compute_line_metrics): Call row_hash, instead of computing the
6470 * dispnew.c (verify_row_hash): Call row_hash for computing the
6471 hash code of a row, instead of duplicating code from xdisp.c.
6473 * dispextern.h (row_hash): Add prototype.
6475 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

6505 occurrences of window_nest to window_combination_limit.
6507 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6509 * image.c (imagemagick_load_image): Fix typo.
6511 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6513 * xdisp.c (display_line): Move the call to
6514 highlight_trailing_whitespace before the call to
6515 compute_line_metrics, since the latter needs to see the final
6516 faces of all the glyphs to compute ROW's hash value.
6517 Fixes assertion violations in row_equal_p. (Bug#10035)
6519 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

6578 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6580 Avoid some portability problems by eschewing 'extern inline' functions.
6581 The trivial performance wins aren't worth the portability hassles; see
6582 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6584 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6586 (window_box_right, window_box_right_offset): Undo previous change,
6587 by removing the "extern"s.
6588 * intervals.c (adjust_intervals_for_insertion)
6589 (adjust_intervals_for_deletion): Undo previous change,
6590 making these static again.
6591 (offset_intervals, temp_set_point_both, temp_set_point)
6592 (copy_intervals_to_string): No longer inline.
6593 * xdisp.c (window_text_bottom_y, window_box_width)

6661 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6662 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6663 * intervals.c (adjust_intervals_for_insertion)

6666 (static_offset_intervals): Remove.
6667 (offset_intervals): Rewrite using the old contents of
6668 static_offset_intervals. The old version didn't conform to C99
6669 because an extern inline function contained a reference to an
6670 identifier with static linkage.

6723 (unwind_create_frame): New function (Bug#9943).
6724 (Fx_create_frame): Restructure code to be more similar to the one in
6725 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

6796 * w32fns.c (unwind_create_frame): If needed, free the glyph
6797 matrices of the partially constructed frame. (Bug#9943)
6798 * xfns.c (unwind_create_frame): Likewise.
6800 2011-11-01 Eli Zaretskii <eliz@gnu.org>
6802 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6803 Don't stop backward scan on the continuation glyph, even though
6804 its CHARPOS is positive.
6805 (mouse_face_from_buffer_pos, note_mouse_highlight):
6806 Rename cover_string to disp_string.
6808 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6810 * window.c (temp_output_buffer_show): Don't use
6811 Vtemp_buffer_show_specifiers.
6812 (Vtemp_buffer_show_specifiers): Remove unused variable.
6814 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6816 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6817 past the beginning of the current glyph matrix.
6819 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
6821 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
6822 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6823 HAVE_GTK3 (Bug#9869).
6825 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6826 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6828 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6830 * xterm.c: Declare x_handle_net_wm_state to return int.
6831 (handle_one_xevent): Check if we are iconified but don't have
6832 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6833 (get_current_wm_state): Return non-zero if not hidden,
6834 check for _NET_WM_STATE_HIDDEN (Bug#9893).
6835 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
6836 (x_handle_net_wm_state): Return what get_current_wm_state returns.
6837 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
6839 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6841 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6842 so that this new function doesn't get optimized away by a
6843 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6845 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6847 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6849 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6851 Fix the `xbytecode' command.
6852 * .gdbinit (xprintbytestr): New command.
6853 (xwhichsymbols): Rename from `which'; all callers changed.
6854 (xbytecode): Print the byte-code string as well.
6856 2011-10-29 Kim Storm <storm@cua.dk>
6858 * alloc.c (which_symbols): New function.
6860 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6862 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6865 2011-10-29 Glenn Morris <rgm@gnu.org>
6867 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6868 Not clear what it was for, and it causes various bugs. (Bug#9839)
6870 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6872 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6873 possible random value that matches one of those tested as
6874 condition to clear the mouse face.
6876 2011-10-28 Chong Yidong <cyd@gnu.org>
6878 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6880 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6882 * window.c (make_window): Initialize phys_cursor_on_p.
6884 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6886 * lisp.h (struct Lisp_Symbol): Update comments.
6888 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6890 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6892 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6894 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6895 <oslsachem@gmail.com> for helping to debug this.
6897 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6898 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6899 (g_b_init_get_glyph_outline_w): New static variables.
6900 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6901 (GetGlyphOutlineW_Proc): New typedefs.
6902 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6903 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6905 (w32font_open_internal, compute_metrics):
6906 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6907 instead of calling the "wide" APIs directly.
6909 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6911 * w32.h (syms_of_w32font): Add prototype.
6913 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6915 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6916 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6917 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6918 (Fmove_to_window_line): Doc fix.
6920 2011-10-27 Chong Yidong <cyd@gnu.org>
6922 * process.c (make_process): Set gnutls_state to NULL.
6924 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6925 non-NULL, regardless of GNUTLS_INITSTAGE.
6926 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6927 an error. Set process slots as soon as we allocate them.
6929 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6931 2011-10-27 Chong Yidong <cyd@gnu.org>
6933 * gnutls.c (emacs_gnutls_deinit): New function.
6934 Deallocate credentials structures as well as calling gnutls_deinit.
6935 (Fgnutls_deinit, Fgnutls_boot): Use it.
6937 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6938 (deactivate_process): Call emacs_gnutls_deinit.
6940 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6942 * image.c (x_create_x_image_and_pixmap):
6943 * w32.c (sys_rename, w32_delayed_load):
6944 * w32font.c (fill_in_logfont):
6945 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6947 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6949 * w32fns.c (w32_default_color_map): New function,
6950 extracted from Fw32_default_color_map.
6951 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6953 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6955 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6957 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6959 * keyboard.c (test_undefined): New function (bug#9751).
6960 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6962 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6964 * sysdep.c (init_sys_modes): Fix the check for the controlling
6965 terminal (Bug#6649).
6967 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6969 * dispextern.h (struct bidi_it): New member next_en_type.
6971 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6972 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6973 current character, check also for next_en_type being WEAK_EN.
6974 (bidi_resolve_weak): Don't enter the expensive loop if the current
6975 position is before next_en_pos. Record the bidi type of the first
6976 non-ET, non-BN character we find, in addition to its position.
6977 (bidi_level_of_next_char): Invalidate next_en_type when
6978 next_en_pos is over-stepped.
6980 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6982 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6983 * editfns.c: Rewrite current-time-zone so that it invokes
6984 the equivalent of (format-time-string "%Z") to get the time zone name.
6985 This fixes a bug when the time zone name contains characters that
6986 need converting from the system time locale to Emacs internal format.
6987 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6988 that patch fixed format-time-string to do the conversion, but
6989 I forgot to fix current-time-zone.
6990 (format_time_string): New function, containing most of
6991 what Fformat_time_string used to contain.
6992 (Fformat_time_string): Rewrite in terms of format_time_string.
6993 This doesn't change this function's behavior.
6994 (current-time-zone): Rewrite to use format_time_string.
6995 This fixes the bug reported by Michael Schierl in
6996 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6997 Jason Rumney's 2007-06-07 change worked around this bug, but
6999 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7001 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7003 * xdisp.c (start_display): If the character at POS is displayed
7004 via a display vector, reset IT->current.dpvec_index to zero.
7005 (try_window_reusing_current_matrix): If a line ends in a display
7006 vector or the next line starts in a display vector, continue
7007 redrawing the window even though the character position of
7008 start_row was reached.
7011 2011-10-18 Chong Yidong <cyd@gnu.org>
7013 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7014 with nobreak-char-display too.
7016 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7018 Fix part 3 of bug#9771.
7019 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7020 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7021 non-neutral characters if the current character is a paragraph
7022 separator (a.k.a. Newline). This avoids running the same
7023 expensive loop twice, once when we consume the preceding newline
7024 and the other time when the line actually needs to be displayed.
7025 Avoid the loop when we see neutrals on the base embedding level
7026 following a character whose directionality is the same as the
7027 paragraph's. This avoids running the expensive loop when a line
7028 ends in a long sequence of neutrals, like control characters.
7029 Add assertion against STRONG_AL type. Slightly rearrange code
7030 that determines the type of a neutral given the first non-neutral
7032 (bidi_level_of_next_char): Set next_en_pos to zero when
7033 invalidating its info.
7035 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7037 * xdisp.c (push_display_prop): Determine whether to record string
7038 or buffer position by IT->string, not by IT->method. Allow
7039 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7040 (move_it_vertically_backward): Don't look for character position
7041 immediately after the newline when in a continuation line.
7044 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7046 * window.c (coordinates_in_window): Rewrite and delabelize
7047 vertical border check. (Bug#5357) (Bug#9618)
7049 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7051 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7052 errors in XSetWindowBorder (bug#9310).
7054 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7056 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7057 avoid crash when xmalloc overrun checking is enabled.
7059 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7061 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7062 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7063 cursor motion with <left> and <right> arrow keys.
7065 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7066 some callers set that themselves.
7068 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7070 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7071 display string and the previous row comes from the same string and
7072 is empty. (Bug#9739) (Bug#9738)
7074 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7076 * doc.c (get_doc_string): Encode file name (bug#9735).
7078 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7080 * bidi.c (bidi_level_of_next_char):
7081 * xdisp.c (get_visually_first_element): Remove old incorrect
7082 comments regarding the Unicode Line Separator character.
7084 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7086 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7088 * alloc.c (Fgc_status): Do not access beyond zombies array
7089 boundary if nzombies > MAX_ZOMBIES.
7090 * alloc.c (dump_zombies): Add missing format specifier.
7092 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7094 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7095 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7097 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7098 Some packages use them to denote characters with modifiers.
7100 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7102 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7103 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7104 matching a pp-number. Rename parameter var to var1.
7106 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7108 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7110 2011-10-08 Glenn Morris <rgm@gnu.org>
7112 * callint.c (Fcall_interactively): Give a more explicit error for the
7113 'c' case with a non-character input. (Bug#8479)
7115 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7117 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7119 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7120 lines that are hscrolled on the left.
7122 * dispnew.c (buffer_posn_from_coords): Account for a possible
7123 presence of header-line. (Bug#4426)
7125 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7127 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7128 Don't advertise functionality which we discourage or doesn't work.
7130 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7132 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7133 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7134 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7135 this makes Emacs dump core during garbage collection on rare
7136 occasions. sizeof is obviously inferior to offsetof here, so
7137 stick with offsetof.
7138 (GC_POINTER_ALIGNMENT): New macro.
7139 (mark_memory): Omit 3rd (offset) arg; caller changed.
7140 Don't assume EMACS_INT alignment is the same as pointer alignment.
7142 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7144 * keyboard.c (read_key_sequence_remapped): New var.
7145 (read_key_sequence): Compute remapping in the right buffer.
7146 (command_loop_1): Use read_key_sequence's remapping directly.
7148 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7150 * dired.c (file_name_completion): Don't expand file name.
7151 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7152 before checking file name handler.
7154 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7155 they've been requested explicitly (bug#9591).
7157 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7159 * keymap.c (Fsingle_key_description): Use make_specified_string
7160 instead of build_string to build string from push_key_description.
7163 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7165 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7166 This fixes a Y2038 bug on 64-bit hosts.
7167 * buffer.c (reset_buffer):
7168 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7169 (Fclear_buffer_auto_save_failure):
7170 Use 0, not -1, to represent an unset failure time, since time_t
7171 might not be signed.
7173 Remove dependency on glibc malloc internals.
7174 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7175 Move back here from lisp.h, but with their new implementations.
7176 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7177 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7178 * charset.c (charset_table_init): New static var.
7179 (syms_of_charset): Use it instead of xmalloc. This removes a
7180 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7181 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7182 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7183 Move back to alloc.c.
7184 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7185 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7187 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7189 * nsterm.m (windowDidResize): Call x_set_window_size only when
7190 ns_in_resize is true. Otherwise set pixelwidth/height and
7191 call change_frame_size (Bug#9628).
7193 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7195 Port --enable-checking=all to Fedora 14 x86-64.
7196 * charset.c (syms_of_charset): Also account for glibc malloc's
7197 internal overhead when calculating the initial malloc maximum.
7199 Port --enable-checking=all to Fedora 14 x86.
7200 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7202 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7203 (overrun_check_realloc, overrun_check_free):
7204 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7205 That way, xmalloc returns a properly-aligned pointer even if
7206 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7207 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7208 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7209 into account when calculating the initial malloc maximum.
7210 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7211 Move here from alloc.c, so that charset.c can use it too.
7212 Properly align; the old code wasn't right for common 32-bit hosts
7213 when configured with --enable-checking=all.
7214 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7215 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7217 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7219 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7222 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7224 * xdisp.c (compute_display_string_end): If there's no display
7225 string at CHARPOS, return -1.
7227 * bidi.c (bidi_fetch_char): When compute_display_string_end
7228 returns a negative value, treat the character as a normal
7229 character not covered by a display string. (Bug#9624)
7231 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7233 * lread.c (Fread_from_string): Fix typo in docstring.
7235 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7237 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7238 newline, reseat the iterator instead of bidi-iterating there one
7239 character at a time. (Bug#9610)
7240 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7241 TO_CHARPOS if the bidi iterator is at base embedding level.
7243 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7245 * lread.c (readevalloop): Use correct code for NBSP.
7246 (read1): Likewise. (Bug#9608)
7248 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7250 * dbusbind.c (Fdbus_register_signal): When service is not
7251 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7253 2011-09-25 Glenn Morris <rgm@gnu.org>

7270 * indent.c (Fvertical_motion): Fix == vs = typo.
7272 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7274 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7275 Default value is now t. Doc fix.
7277 * indent.c (Fvertical_motion): Compute and apply the overshoot
7278 logic when moving up, not only when moving down. Fix the
7279 confusing name and values of the it_overshoot_expected variable;
7280 logic changes accordingly. (Bug#9254) (Bug#9549)
7282 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7283 CHARPOS is covered by a display string which includes newlines.
7284 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7285 is covered by a display string with embedded newlines.
7287 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7289 * dbusbind.c (Fdbus_register_signal): Add match rule to
7290 Vdbus_registered_objects_table. (Bug#9581)
7291 (Fdbus_register_method, Vdbus_registered_objects_table):
7294 2011-09-24 Jim Meyering <meyering@redhat.com>
7296 do not ignore write error for any output size
7297 The previous change was incomplete.
7298 While it makes emacs --batch detect the vast majority of stdout
7299 write failures, errors were still ignored whenever the output size is
7300 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7301 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7302 && echo FAIL: ignored write error
7303 FAIL: ignored write error
7304 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7305 && echo FAIL: ignored write error
7306 FAIL: ignored write error
7307 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7309 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7311 * emacs.c (Fkill_emacs): In noninteractive mode exit
7312 non-successfully if a write error occurred on stdout. (Bug#9574)
7314 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7316 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7319 * dispextern.h (struct it): Update the comment documenting what
7322 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7324 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7325 a display string, extend search for cursor position to end of row.
7326 (find_row_edges): If the row ends in a newline from a display
7327 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7328 Handle the case of a display string with multiple newlines.
7329 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7330 non-empty line. Fixes confusing cursor motion with arrow keys at
7331 the beginning of a line that starts with whitespace.
7333 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7335 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7338 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7340 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7343 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7345 * xdisp.c (display_line): Record maximum and minimum buffer
7346 positions even if no glyphs were produced (e.g., by a zero-width
7347 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7348 buffer positions that will be removed from the glyph row because
7350 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7351 column is beyond frame width: don't subtract 1 "pixel" when
7352 computing width of the stretch.
7353 (reseat_at_next_visible_line_start): Undo the change made on
7354 2011-09-17 that saved paragraph information and restored it after
7355 the call to `reseat'. (Bug#9545)
7357 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7359 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7360 and turn window cursor on if cleared (Bug#9415).
7362 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7364 * search.c (boyer_moore): Take unibyte characters from pattern
7365 literally. (Bug#9458)
7367 2011-09-18 Eli Zaretskii <eliz@gnu.org>

7371 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7373 Fix minor problem found by static checking.
7374 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7375 initialized, to pacify gcc -Wuninitialized.
7377 * fileio.c: Report proper errno when syscall falls.
7378 (Finsert_file_contents): Save and restore errno,
7379 so that report_file_error outputs the correct diagnostic.
7380 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7382 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7384 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7386 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7388 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7389 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7391 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7393 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7394 about the current paragraph and restore it after the call to reseat.
7396 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7397 (bidi_find_paragraph_start): Search back for paragraph beginning
7398 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7399 (bidi_move_to_visually_next): Only trigger paragraph-related
7400 computations when the last character is a newline or at EOB, not
7401 just any NEUTRAL_B. (Bug#9470)
7403 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7404 truncated lines if point is covered by a display string. (Bug#9524)
7406 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7408 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7409 (cons_to_x_long): New function.
7410 (lisp_data_to_selection_data): Use it. Correct the test for
7411 short-versus-long data; it was negated. Break out of vector
7412 loop, for efficiency, when a long datum is discovered.
7414 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7416 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7418 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7420 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7421 GCC PR/17406) by declaring this function with external scope.
7423 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7425 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7426 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7428 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7430 * editfns.c (Fformat): Correctly handle text properties on "%%".

7440 of TAB characters in a composition.
7442 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7444 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7445 This occurs when processing a multibyte format.
7446 Problem reported by Wolfgang Jenker.
7448 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7450 * xdisp.c (try_cursor_movement): Only check for exact match if
7451 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7453 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7455 Remove unused external symbols.
7456 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7457 * xdisp.c (calc_pixel_width_or_height): Now static.
7458 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7459 * indent.c (check_display_width):
7460 * w32term.c: Fix comment to match code.
7461 * xterm.c, xterm.h (x_catching_errors): Remove.
7463 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7465 * xselect.c: Use signed conversions more consistently (Bug#9498).
7466 (selection_data_to_lisp_data): Assume incoming selection data are
7467 signed integers, not unsigned. This is to be consistent with
7468 outgoing selection data, which was modified to use signed integers
7469 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7470 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7471 expects long, not unsigned long.
7473 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7475 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7476 computation of loop end. Reported by Johan Bockgård
7479 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7481 * frame.c (Fother_visible_frames_p): Function deleted.
7483 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7485 * indent.c (compute_motion): Process display vector front to back
7486 rather than the other way around. (Bug#2496)
7488 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7490 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7492 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7494 * minibuf.c (Fread_from_minibuffer): Doc fix.
7496 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7498 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7499 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7501 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7503 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7504 value for non-existent files.
7506 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7508 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7509 set its "size" to -1. This will set the modtime_size field of
7510 the corresponding buffer to -1, which is what
7511 verify-visited-file-modtime expects for files that do not exist.
7514 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7516 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7518 * lisp.h: ... from here. push_key_description is no longer
7519 defined in keyboard.c, so its declaration should not be in
7520 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7521 logically belongs with push_key_description.
7523 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7525 * buffer.h: Include <sys/types.h> instead of <time.h>.
7526 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7527 Problem reported by Herbert J. Skuhra.
7529 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7531 * xml.c (parse_region): Make the parsing work for
7532 non-comment-starting XML files again (bug#9144).
7534 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7536 * image.c (gif_load): Fix calculation of bottom and right corner.
7539 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7541 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7542 redisplay in small windows.
7544 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7546 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7548 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7550 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7551 Operate on live windows only.
7553 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7555 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7557 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7559 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7560 only under bidi iteration.
7562 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7564 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7566 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7568 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7569 Without this fix, the command to link temacs failed due to an
7570 undefined symbol __builtin_isnan. This is because
7571 /usr/include/iso/math_c99.h #defines isnan(x) to
7572 __builtin_isnan(x), but the bundled gcc, which identifies itself
7573 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7575 * floatfns.c (isnan): #undef, and then #define to a clone of
7577 (Fisnan): Always define, since it's always available now.
7578 (syms_of_floatfns): Always define isnan at the Lisp level.
7580 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7582 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7584 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7586 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7587 The previous code assumed that file offsets (off_t values) fit in
7588 EMACS_INT variables, which is not true on typical 32-bit hosts.
7589 The code messed up by falsely reporting buffer overflow in cases
7590 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7591 when "big" contains more than 2**29 bytes, even though this
7592 inserts just one byte and does not overflow the buffer.
7593 (Finsert_file_contents): Store file offsets as off_t
7594 values, not as EMACS_INT values. Check for overflow when
7595 converting between EMACS_INT and off_t. When checking for
7596 buffer overflow or for overlap, take the offsets into account.
7597 Don't use EMACS_INT for small values where int suffices.
7598 When checking for overlap, fix a typo: ZV was used where
7599 ZV_BYTE was intended.
7600 (Fwrite_region): Don't assume off_t fits into 'long'.
7601 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7603 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7605 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7607 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7609 sprintf-related integer and memory overflow issues (Bug#9412).
7611 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7612 (esprintf, exprintf, evxprintf): New functions.
7613 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7614 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7615 (modify_event_symbol): Do not assume that the length of
7616 name_alist_or_stem is safe to alloca and fits in int.
7617 (Fexecute_extended_command): Likewise for function name and binding.
7618 (Frecursion_depth): Wrap around reliably on integer overflow.
7619 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7620 since some callers pass EMACS_INT values.
7621 (Fsingle_key_description): Don't crash if symbol name contains more
7622 than MAX_ALLOCA bytes.
7623 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7624 (get_minibuffer): Arg is now EMACS_INT, not int.
7625 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7626 (esprintf, exprintf, evxprintf): New decls.
7627 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7629 * dbusbind.c (signature_cat): New function.
7630 (xd_signature, Fdbus_register_signal):
7631 Do not overrun buffer; instead, report string overflow.
7633 * dispnew.c (add_window_display_history): Don't overrun buffer.
7634 Truncate instead; this is OK since it's just a log.
7636 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7637 even if the time zone offset is outlandishly large.
7638 Don't mishandle offset == INT_MIN.
7640 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7641 when creating daemon; the previous buffer-overflow check was incorrect.
7643 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7644 which has the guts of the old verror function.
7646 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7647 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7649 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7650 (font_unparse_xlfd): Don't blindly alloca long strings.
7651 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7652 fits in int, when using sprintf. Use single snprintf to count
7653 length of string rather than counting it via multiple sprintfs;
7654 that's simpler and more reliable.
7655 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7656 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7657 sprintf, in case result does not fit in int.
7659 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7660 (fontset_from_font): Print it.
7662 * frame.c (tty_frame_count): Now printmax_t, not int.
7663 (make_terminal_frame, set_term_frame_name): Print it.
7664 (x_report_frame_params): In X, window IDs are unsigned long,
7665 not signed long, so print them as unsigned.
7666 (validate_x_resource_name): Check for implausibly long names,
7667 and don't assume name length fits in 'int'.
7668 (x_get_resource_string): Don't blindly alloca invocation name;
7669 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7672 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7673 (xg_check_special_colors, xg_set_geometry):
7674 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7676 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7677 Use esprintf, not sprintf, in case result does not fit in int.
7679 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7680 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7681 it as a large positive number.
7682 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7683 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7685 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7686 in case result does not fit in int.
7688 * print.c (float_to_string): Detect width overflow more reliably.
7689 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7690 buffer overrun. Don't assume list length fits in 'int'. Treat
7691 print length of 0 as 0, not as infinity; to be consistent with other
7692 uses of print length in this function. Don't overflow print length
7693 index. Don't assume hash table size fits in 'long', or that
7694 vectorlike size fits in 'unsigned long'.
7696 * process.c (make_process): Use printmax_t, not int, to format
7697 process-name gensyms.
7699 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7701 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7702 to avoid potential buffer overrun.
7704 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7705 if X resource line is longer than 512 bytes.
7707 * xfns.c (x_window): Make sprintf buffer a bit bigger
7708 to avoid potential buffer overrun.
7710 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7712 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7714 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7716 Integer overflow fixes for scrolling, etc.
7717 Without these, Emacs silently mishandles large integers sometimes.
7718 For example, "C-u 4294967297 M-x recenter" was treated as if
7719 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7721 * xdisp.c (try_window_id): Check Emacs fixnum range before
7722 converting to 'int'.
7724 * window.c (window_scroll_line_based, Frecenter):
7725 Check that an Emacs fixnum is in range before assigning it to 'int'.
7726 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7727 values converted from Emacs fixnums.
7728 (Frecenter): Don't wrap around a line count if it is out of 'int'
7729 range; instead, treat it as an extreme value.
7730 (Fset_window_configuration, compare_window_configurations):
7731 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7733 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7734 that can exceed INT_MAX. Check that EMACS_INT value is in range
7735 before assigning it to the (possibly-narrower) index.
7736 (match_limit): Don't assume that a fixnum can fit in 'int'.
7738 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7741 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7742 (Fvertical_motion): Don't wrap around LINES values that don't fit
7743 in 'int'. Instead, treat them as extreme values. This is good
7744 enough for windows, which can't have more than INT_MAX lines anyway.
7746 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7748 * Require libxml/parser.h to avoid compilation warning.
7750 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7752 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7753 since this reportedly can destroy thread storage.
7755 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7757 * syntax.c (find_defun_start): Update all cache variables if
7758 exiting early (Bug#9401).
7760 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7762 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7764 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7765 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7766 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7768 * term.c (tty_append_glyph): New function.
7769 (produce_stretch_glyph): Static function and its prototype deleted.
7771 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7774 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7776 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7777 when checking :margin (Bug#9390).
7778 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7779 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7780 so that the name doesn't mislead. All uses changed.
7782 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7784 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7787 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7789 * xdisp.c (move_it_to): Don't bail out early when reaching
7790 position beyond to_charpos, if we are scanning backwards.
7791 (move_it_vertically_backward): When DY == 0, make sure we get to
7792 the first character in the line after the newline.
7794 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7796 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7797 (ccl_driver): Do not generate an out-of-range pointer.
7798 (Fccl_execute_on_string): Remove unnecessary check for
7799 integer overflow, noted by Stefan Monnier in
7800 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7801 Remove a FIXME that didn't need fixing.
7802 Simplify the newly-introduced buffer reallocation code.
7804 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7806 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7808 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7810 Integer and memory overflow issues (Bug#9196).
7812 * doc.c (get_doc_string): Rework so that
7813 get_doc_string_buffer_size is the actual buffer size, rather than
7814 being 1 less than the actual buffer size; this makes xpalloc more
7817 * image.c (x_allocate_bitmap_record, cache_image):
7818 * xselect.c (Fx_register_dnd_atom):
7819 Simplify previous changes by using xpalloc.
7821 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7822 since either will do and ptrdiff_t is convenient with xpalloc.
7824 * charset.c (charset_table_size)
7825 (struct charset_sort_data.priority): Now ptrdiff_t.
7826 (charset_compare): Don't overflow if priorities differ greatly.
7827 (Fsort_charsets): Don't assume list length fits in int.
7828 Check for size-calculation overflow when allocating sort data.
7829 (syms_of_charset): Allocate an initial charset table that is
7830 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7832 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7834 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7835 The actual value is always <= INT_MAX, and leaving it unsigned made
7836 overflow checking harder.
7838 * dispextern.h (struct glyph_matrix.rows_allocated)
7839 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7840 with xpalloc. The values are still always <= INT_MAX.
7842 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7844 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7845 (SAFE_NALLOCA): New macro.

7849 (set_cache_region, invalidate_region_cache)
7850 (revalidate_region_cache, know_region_cache, region_cache_forward)
7851 (region_cache_backward, pp_cache):
7852 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7853 so that ptrdiff_t * can be passed to xpalloc.
7854 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7855 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7856 (pp_cache): Don't assume cache_len fits in int.
7857 * region-cache.h: Adjust extern decls to match.
7859 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7860 EMACS_INT, since either will do, for xpalloc.
7862 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7863 (xnmalloc, xnrealloc, xpalloc): New functions.
7865 * bidi.c (bidi_shelve_header_size): New constant.
7866 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7867 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7869 * bidi.c (bidi_cache_shrink):
7870 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7872 Don't update size of array until after memory allocation succeeds,
7873 because xmalloc/xrealloc may not return.
7874 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7875 now that we have proper integer overflow checking.
7876 (record_overlay_string, overlay_strings): Catch overflows when
7877 calculating size of overlay_str_buf.
7879 * callproc.c (Fcall_process): Check for size overflow when
7880 calculating size of args2.
7881 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7882 Normally we prefer signed values, but sticking with ptrdiff_t would
7883 require adding more-complicated checks.
7885 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7886 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7887 Redo buffer-overflow calculations to avoid integer overflow.
7888 Add a FIXME comment where memory seems to be over-allocated.
7890 * character.c (Fstring): Check for size-calculation overflow.
7892 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7893 unnecessary integer overflow. Check for size overflow.
7894 (encode_coding_object): Don't update size until xmalloc succeeds.
7896 * composite.c (get_composition_id): Check for overflow in glyph
7897 length calculations.
7899 Integer and memory overflow fixes for display code.

7901 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7902 (scrolling_window): Check for overflow in size calculations.
7903 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7915 (get_doc_string): Check for size calculation overflow.
7916 Don't update size until allocation succeeds.
7917 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7918 EMACS_INT, where ptrdiff_t will do.
7919 (Fsubstitute_command_keys): Check for string overflow.
7921 * editfns.c (set_time_zone_rule): Don't assume environment length
7923 (message_length): Now ptrdiff_t, not int.
7924 (Fmessage_box): Don't update size until allocation succeeds.
7925 Don't assume message length fits in int.
7926 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7928 * emacs.c (main): Do not reallocate argv, since there is a null at
7929 the end that can be overwritten, and this way there's no need to
7930 worry about size-calculation overflow.
7931 (sort_args): Check for size-calculation overflow.
7933 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7935 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7937 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7938 (x_set_scroll_bar_width, x_figure_window_size):
7939 Check for integer overflow.
7940 (x_set_alpha): Do not assume XINT fits in int.
7942 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7943 This is for the members text_lines, text_cols, total_lines, total_cols,
7944 where the system imposes an 'int' limit.
7946 * fringe.c (Fdefine_fringe_bitmap):
7947 Don't update size until alloc works.
7949 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7950 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7952 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7953 Check for size-calculation overflow.
7954 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7955 do, as we prefer signed integers.
7956 (id_to_widget.max_size, id_to_widget.used)
7957 (xg_store_widget_in_map, xg_remove_widget_from_map)
7958 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7959 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7960 Use and return ptrdiff_t, not int.
7961 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7962 * gtkutil.h: Change prototypes to match the above.
7964 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7965 are duplicate now that they've been promoted to lisp.h.
7966 (x_allocate_bitmap_record, x_alloc_image_color)
7967 (make_image_cache, cache_image, xpm_load):
7968 Don't update size until alloc is done.

7978 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7979 Use ptrdiff_t, not int, to count maps.
7980 (read_char_minibuf_menu_prompt): Check for overflow in size

7996 Now ptrdiff_t, not int.
7997 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

8009 (Fset_match_data): Don't assume list lengths fit in 'int'.
8011 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8012 for command line length. Do not attempt to address one before the

8018 (encode_terminal_code, calculate_costs): Check for size
8019 calculation overflow.

8041 Use ptrdiff_t, not int, for sizes.
8042 (Finternal_make_lisp_face, cache_face):
8043 Check for size calculation overflow.
8044 (cache_face): Treat size calculation overflows as if they were
8045 memory exhaustion (the usual treatment), rather than aborting.
8047 * xfns.c (x_encode_text, x_set_name_internal)
8048 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8049 sizes, since they can exceed INT_MAX in size. Check for size

8053 (xg_select): Check for size calculation overflow.
8054 Don't update size until alloc done.
8056 * xrdb.c (get_environ_db): Don't assume path length fits in int,

8060 (X_LONG_MIN): New macros.
8061 Use them to make the following changes clearer.
8062 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8063 This change doesn't affect the value now, but it may help remind
8064 future maintainers not to raise the value too much later.
8065 (SELECTION_QUANTUM): Remove, replacing with ...
8066 (selection_quantum): ... new function, which avoids overflow.
8068 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

8077 Redo calculations to avoid overflow.
8078 (x_reply_selection_request): When sending hint, ceiling it at
8079 X_LONG_MAX rather than relying on wraparound overflow to send

8082 (lisp_data_to_selection_data, x_property_data_to_lisp):
8083 Check for size-calculation overflow.

8086 Don't store size until memory allocation succeeds.
8087 (x_get_window_property): Plug memory leak on memory exhaustion.
8088 Don't double-block input; malloc is safe here. Don't assume 2**34
8089 - 4 fits in unsigned long. Add an xassert to check
8090 XGetWindowProperty overflow. Be more careful about overflow
8091 calculations, and distinguish size from memory overflow better.
8092 (receive_incremental_selection): When tracing, don't assume
8093 unsigned int is less than INT_MAX.
8094 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8095 harmful) conversions of unsigned short to int.
8096 (lisp_data_to_selection_data): Don't assume that integers
8097 in the range -65535 through -1 fit in an X unsigned short.
8098 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8099 result parameters unless successful. Rely on cons_to_unsigned
8100 to report problems with elements; the old code wasn't right anyway.
8101 (x_check_property_data): Check for int overflow; we cannot use
8102 a wider type due to X limits.
8103 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8134 * image.c (xpm_get_color_table_h):
8135 * lisp.h (hash_lookup, hash_put):
8136 * minibuf.c (Ftest_completion):
8137 Use ptrdiff_t for hash table indexes, not int (which is too
8138 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8139 32-bit --with-wide-int hosts).
8141 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8142 Add a FIXME comment about memory leaks.

8147 * character.h (CHAR_WIDTH):
8148 * indent.c (MULTIBYTE_BYTES_WIDTH):
8149 Use sanitize_char_width to avoid undefined and/or bad behavior
8150 with outlandish widths.
8151 * character.h (sanitize_tab_width): Rename from sanitize_width,
8152 now that we have two such functions. All uses changed.
8153 (sanitize_char_width): New inline function.
8155 Don't assume that tab-width fits in int.

8177 (make_lispy_movement): Use same integer type in forward decl
8178 that is used in the definition.
8179 (read_key_sequence, keyremap_step):
8180 Change bufsize argument back to int, undoing my 2011-03-30 change.
8181 We prefer signed types, and int is wide enough here.
8182 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8183 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8184 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8185 length, not size_t. Use ptrdiff_t for index, not int.
8186 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8187 possibility of integer overflow.
8189 Overflow, signedness and related fixes for images.
8191 * dispextern.h (struct it.stack[0].u.image.image_id)
8192 (struct_it.image_id, struct image.id, struct image_cache.size)
8193 (struct image_cache.used, struct image_cache.ref_count):
8194 * gtkutil.c (update_frame_tool_bar):
8195 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
8196 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
8197 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
8198 * nsmenu.m (update_frame_tool_bar):
8199 * xdisp.c (calc_pixel_width_or_height):
8200 * xfns.c (image_cache_refcount):
8201 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8202 on typical 64-bit hosts.
8204 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8205 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
8206 Omit unnecessary casts to int.

8208 when the callers expect that.
8209 (image_ascent): Redo ascent calculation to avoid int overflow.
8210 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8211 (lookup_image): Remove unnecessary tests.
8212 (xbm_image_p): Locals are now of int, not EMACS_INT,
8213 since parse_image_check makes sure they fit into int.
8214 (png_load, gif_load, svg_load_image):
8215 Prefer int to unsigned where either will do.
8216 (tiff_handler): New function, combining the cores of the
8217 old tiff_error_handler and tiff_warning_handler.
8218 This function is rewritten to use vsnprintf and thereby avoid
8219 stack buffer overflows. It uses only the features of vsnprintf
8220 that are common to both POSIX and native Microsoft.
8221 (tiff_error_handler, tiff_warning_handler): Use it.
8222 (tiff_load, gif_load, imagemagick_load_image):
8223 Don't assume :index value fits in 'int'.
8224 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8225 (imagemagick_load_image): Check that crop parameters fit into
8226 the integer types that MagickCropImage accepts. Don't assume
8227 Vimagemagick_render_type has a nonnegative value. Don't assume
8228 size_t fits in 'long'.
8229 (gs_load): Use printmax_t to print the widest integers possible.
8230 Check for integer overflow when computing image height and width.
8232 2011-08-26 Eli Zaretskii <eliz@gnu.org>
8234 * xdisp.c (redisplay_window): Don't force window start if point

8242 handle_single_display_spec, not just 1 or zero.
8243 (handle_single_display_spec): If the display spec is of the form
8244 `(space ...)', and specifies display in the text area, return 2
8246 (try_cursor_movement): Check for the need to scroll more
8247 accurately, and prefer exact match for point under bidi.
8248 Don't advance `row' beyond the last row of the window.
8250 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8251 into disp_prop; all users changed.
8253 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8265 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8266 buffers, return left-to-right.
8267 (set_cursor_from_row): Consider candidate row a win if its glyph
8268 represents a newline and point is on that newline. Fixes cursor
8269 positioning on the newline at EOL of R2L text within L2R
8270 paragraph, and vice versa.
8271 (try_cursor_movement): Check continued rows, in addition to
8272 continuation rows. Fixes unwarranted scroll when point enters a
8273 continued line of R2L text within an L2R paragraph, or vice versa.
8274 (cursor_row_p): Consider the case of point being equal to
8275 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8276 from the end of a short line to the beginning of a continued line
8277 of R2L text within L2R paragraph.
8278 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8279 composed characters.
8281 * bidi.c (bidi_check_type): Use xassert.
8282 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8285 2011-08-23 Eli Zaretskii <eliz@gnu.org>

8294 2011-08-22 Kenichi Handa <handa@m17n.org>
8296 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8297 extra slot even if the purpose is char-code-property-table.
8299 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8301 * xdisp.c (redisplay_window): When computing centering_position,
8302 account for the height of the header line. (Bug#8874)
8304 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8305 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8306 candidate is selected by the mouse, and that candidate has a
8307 composed character under the mouse.
8309 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8310 coordinates reported by pos-visible-in-window-p for a composed
8311 character in column zero.

8317 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8319 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8320 consider it a hit if to_charpos is anywhere in the range of the
8321 composed buffer positions.
8323 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8325 * image.c (gif_load): Don't assume that each subimage has the same
8326 dimensions as the base image. Handle disposal method that is
8327 "undefined" by the gif spec (Bug#9335).
8329 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8331 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8332 (Fcondition_case): Document `debug' symbol in error handler.
8334 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8336 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8337 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8338 from an Org mode buffer to a Speedbar frame.
8340 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8341 a composition, take its buffer position from IT->cmp_it.charpos.
8342 Fixes cursor positioning at the beginning of a line that begins
8343 with a composed character.
8345 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8347 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8348 character bidirectional type, use STRONG_L instead. Fixes crashes
8349 in a buffer produced by `describe-categories'.
8351 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8352 members before the level stack, so they would be saved and
8353 restored when copying iterator state. Fixes incorrect reordering
8354 around TABs covered by display properties.
8356 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8358 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8363 (internal_condition_case_2, internal_condition_case_n):
8364 Remove unnecessary aborts (Bug#9081).
8366 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8368 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8369 has no `load' handler, try opening the file locally. (Bug#9311)
8371 2011-08-16 Ken Brown <kbrown@cornell.edu>

8486 Set IT->current to match the bidi iterator unconditionally.
8487 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8488 entry. Force push_it to save on the stack the current
8489 buffer/string position, to be restored by pop_it. Fix flags in
8490 the iterator structure wrt the object coming from a display
8491 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8492 properties. (Bug#9284)
8494 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8496 * fontset.c (fontset_get_font_group): Add proper type checks.

8551 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8552 amount allocated this far in `bidi_cache_total_alloc'.
8553 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if

8676 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8677 or scroll bar (Bug#8470).
8679 * nsfont.m (nsfont_open): Remove assignment to voffset and
8680 unnecessary vars hshink, expand, hd, full_height, min_height.
8681 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8683 * nsterm.h (nsfont_info): Remove voffset field.
8685 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8687 Implement strike-through and overline on NextStep (Bug#8863).
8689 * nsfont.m (nsfont_open): Use underline position provided by font,
8690 instead of hard-coded value of 2.
8691 (nsfont_draw): Call ns_draw_text_decoration instead.
8693 * nsterm.h: Add declaration for ns_draw_text_decoration.
8695 * nsterm.m (ns_draw_text_decoration): New function for drawing
8696 underline, overline, and strike-through.
8697 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8698 ns_draw_text_decoration. Change treatment of cursor drawing to
8699 accommodate underlining, etc.
8701 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8703 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8706 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8708 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8709 Without this fix, if a signal arrives just after memory fills up,
8710 'malloc' might be invoked reentrantly.
8712 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8713 In other words, assume that every image size is allowed, on non-X
8714 hosts. This assumption is probably wrong, but it lets Emacs compile.
8716 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8718 * regex.c (re_iswctype): Convert return values to boolean.
8720 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8722 * xdisp.c (compute_display_string_pos): Don't use cached display
8723 string position if the buffer had its restriction changed.
8726 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8728 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8730 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8732 Integer signedness and overflow and related fixes. (Bug#9079)
8734 * bidi.c: Integer size and overflow fixes.
8735 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8736 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8737 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8738 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8739 (bidi_find_other_level_edge):
8740 Use ptrdiff_t instead of EMACS_INT where either will do.
8741 This works better on 32-bit hosts configured --with-wide-int.
8742 (bidi_cache_ensure_space): Check for size-calculation overflow.
8743 Use % rather than repeated addition, for better worst-case speed.
8744 Don't set bidi_cache_size until after xrealloc returns, because it
8746 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8747 (bidi_cache_ensure_space): Also check that the bidi cache size
8748 does not exceed that of the largest Lisp string or buffer. See Eli
8749 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8751 * alloc.c (__malloc_size_t): Remove.
8752 All uses replaced by size_t. See Andreas Schwab's note
8753 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8755 * image.c: Improve checking for integer overflow.
8756 (check_image_size): Assume that f is nonnull, since
8757 it is always nonnull in practice. This is one less thing to
8758 worry about when checking for integer overflow later.
8759 (x_check_image_size): New function, which checks for integer
8760 overflow issues inside X.
8761 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8762 This removes the need for a memory_full check.
8763 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8764 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8765 (xbm_read_bitmap_data): Change locals back to 'int', since
8766 their values must fit in 'int'.
8767 (xpm_load_image, png_load, tiff_load):
8768 Invoke x_create_x_image_and_pixmap earlier,
8769 to avoid much needless work if the image is too large.
8770 (tiff_load): Treat overly large images as if
8771 x_create_x_image_and_pixmap failed, not as malloc failures.
8772 (gs_load): Use x_check_image_size.
8774 * gtkutil.c: Omit integer casts.
8775 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8776 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8778 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8780 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8781 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8782 would wrongly return t on a 64-bit host.
8784 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8785 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8786 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8787 and therefore cause GCC to emit a bogus diagnostic in some cases.
8789 * image.c: Integer signedness and overflow and related fixes.
8790 This is not an exhaustive set of fixes, but it's time to
8791 record what I've got.
8792 (lookup_pixel_color, check_image_size): Remove redundant decls.
8793 (check_image_size): Don't assume that arbitrary EMACS_INT values
8794 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8795 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8796 (tiff_load, imagemagick_load_image):
8797 Check for overflow in size calculations.
8798 (x_create_x_image_and_pixmap): Remove unnecessary test for
8799 xmalloc returning NULL; that can't happen.
8800 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8801 (xpm_color_bucket): Use better integer hashing function.
8802 (xpm_cache_color): Don't possibly over-allocate memory.
8803 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8804 (gif_memory_source):
8805 Use ptrdiff_t, not int or size_t, to record sizes.
8806 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8807 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8808 either works, as we prefer signed integers.
8809 (tiff_read_from_memory, tiff_write_from_memory):
8810 Return tsize_t, not size_t, since that's what the TIFF API wants.
8811 (tiff_read_from_memory): Don't fail simply because the read would
8812 go past EOF; instead, return a short read.
8813 (tiff_load): Omit no-longer-needed casts.
8814 (Fimagemagick_types): Don't assume size fits into 'int'.
8816 Improve hashing quality when configured --with-wide-int.
8817 * fns.c (hash_string): New function, taken from sxhash_string.
8818 Do not discard information about ASCII character case; this
8819 discarding is no longer needed.
8820 (sxhash-string): Use it. Change sig to match it. Caller changed.
8821 * lisp.h: Declare it.
8822 * lread.c (hash_string): Remove, since we now use fns.c's version.
8823 The fns.c version returns a wider integer if --with-wide-int is
8824 specified, so this should help the quality of the hashing a bit.
8826 * emacs.c: Integer overflow minor fix.
8827 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8828 Define only if GNU_LINUX.
8829 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8831 * dispnew.c: Integer signedness and overflow fixes.
8832 Remove unnecessary forward decls, that were a maintenance hassle.
8833 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8835 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8836 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8837 (prepare_desired_row, line_draw_cost):
8838 Use int, not unsigned, where either works.
8839 (save_current_matrix, restore_current_matrix):
8840 Use ptrdiff_t, not size_t, where either works.
8841 (init_display): Check for overflow more accurately, and without
8842 relying on undefined behavior.
8844 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8845 Remove, replacing with the new symbols in lisp.h. All uses changed.
8846 * fileio.c (make_temp_name):
8847 * filelock.c (lock_file_1, lock_file):
8848 * xdisp.c (message_dolog):
8849 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8850 Use pMd etc. instead.
8851 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8852 replacing the pWIDE etc. symbols removed from editfns.c.
8854 * keyboard.h (num_input_events): Now uintmax_t.
8855 This is (very slightly) less likely to mess up due to wraparound.
8858 * buffer.c: Integer signedness fixes.
8859 (alloc_buffer_text, enlarge_buffer_text):
8860 Use ptrdiff_t rather than size_t when either will do, as we prefer
8863 * alloc.c: Integer signedness and overflow fixes.
8864 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8865 (__malloc_size_t): Default to size_t, not to int.
8866 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8867 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8868 Prefer ptrdiff_t to size_t when either would do, as we prefer
8870 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8871 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8872 Now const. Initialize with values that are in range even if char
8874 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8875 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8876 These functions do the right thing with sizes > 2**32.
8877 (check_depth): Now ptrdiff_t, not int.
8878 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8879 Adjust to new way of storing sizes. Check for size overflow bugs
8881 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8882 slightly wrong anyway, as it missed one instance of
8883 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8884 (refill_memory_reserve): Omit needless cast to size_t.
8885 (mark_object_loop_halt): Mark as externally visible.
8887 * xselect.c: Integer signedness and overflow fixes.
8888 (Fx_register_dnd_atom, x_handle_dnd_message):
8889 Use ptrdiff_t, not size_t, since we prefer signed.
8890 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8891 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8892 x_dnd_atoms_size and x_dnd_atoms_length.
8894 * doprnt.c: Prefer signed to unsigned when either works.
8896 * doprnt.c (doprnt):
8898 * xdisp.c (vmessage):
8899 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8900 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8901 prefer signed arithmetic to avoid comparison confusion.
8902 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8903 but is a bit tricky.
8905 Assume freestanding C89 headers, string.h, stdlib.h.
8906 * data.c, doprnt.c, floatfns.c, print.c:
8907 Include float.h unconditionally.
8908 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8909 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8910 * regex.c: Likewise for stddef.h, string.h.
8911 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8912 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8913 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8914 (STDC_HEADERS): Remove obsolete defines.
8915 * sysdep.c: Include limits.h unconditionally.
8917 Assume support for memcmp, memcpy, memmove, memset.
8918 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8919 * regex.c (memcmp, memcpy):
8920 Remove; we assume C89 now.
8922 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8923 (__malloc_safe_bcopy): Remove; no longer needed.
8925 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8926 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8927 well either way, and we prefer signed to unsigned.
8929 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8931 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8932 closes the connection while we're reading (bug#9182).
8934 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8936 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8937 are specified (Bug#9168).
8939 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8941 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8942 Found by GCC static checking and --with-wide-int on a 32-bit host.
8944 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8946 * xdisp.c (compute_display_string_pos): Fix logic of caching
8947 previous display string position. Initialize cached_prev_pos to
8948 -1. Fixes slow-down at the beginning of a buffer.
8950 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8952 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8953 for attrs[LFACE_FONTSET_INDEX].
8955 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8957 * xml.c (parse_region): Remove unused local
8958 that was recently introduced.
8960 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8962 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8963 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8965 * xdisp.c (move_it_in_display_line_to): Record the best matching
8966 position for TO_CHARPOS while scanning the line, and restore it on
8967 exit if none of the characters scanned was an exact match.
8968 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8969 when exact match is impossible due to invisible text, and the
8970 lines are truncated.
8972 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8974 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8977 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8979 Fix a significant slow-down of cursor motion with C-n, C-p,
8980 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8981 auto-repeat under bidi redisplay in fontified buffers.
8982 * xdisp.c (compute_stop_pos_backwards): New function.
8983 (next_element_from_buffer): Call compute_stop_pos_backwards to
8984 find a suitable prev_stop when we find ourselves before
8986 (reseat): Don't look for prev_stop, as that could mean a very long
8988 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8989 <cached_disp_overlay_modiff>: Cache for last found display string
8991 (compute_display_string_pos): Return the cached position if asked
8992 about the same buffer in the same area of character positions, and
8993 the buffer wasn't changed since the time the display string
8994 position was cached.
8996 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8998 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8999 is an integer, which is important for empty lines. (Bug#9149)
9001 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9003 * frame.c (Fmodify_frame_parameters): In tty case, update the
9004 default face if necessary (Bug#4238).
9006 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9008 * editfns.c (Fstring_to_char): No need to explain what a character
9009 is in the docstring (Bug#6576).
9011 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9013 * xml.c (parse_region): Make sure we always return a tree.
9015 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9017 * xml.c (parse_region): If a document contains only comments,
9020 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9022 * xml.c (make_dom): Return comments, too.
9024 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9027 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9028 and the surrounding thread.
9029 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9030 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9031 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9033 * s/openbsd.h (BROKEN_SIGIO): Define.
9034 * unexelf.c (unexec) [__OpenBSD__]:
9035 Don't update the .mdebug section of the Alpha COFF symbol table.
9037 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9039 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9042 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9044 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9045 This fixes some race conditions on the permissions of any newly
9048 * alloc.c (valid_pointer_p): Use pipe, not open.
9049 This fixes some permissions issues when debugging.
9051 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9052 If fchown fails to set both uid and gid, try to set just gid,
9053 as that is sometimes allowed. Adjust the file's mode to eliminate
9054 setuid or setgid bits that are inappropriate if fchown fails.
9056 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9058 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9059 to compare Lisp_Objects.
9060 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9061 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9062 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9064 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9066 * lread.c (read_integer): Unread even EOF character.
9067 (read1): Likewise. Properly record start position of symbol.
9069 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9070 symbol character follows.
9072 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9074 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9075 This works around a problem with the previous change to Fcopy_file.
9076 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9077 and without this change, GCC might complain about discarding
9078 fchown's return value.
9080 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9082 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9084 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9086 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9088 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9090 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9091 it's used from the C level.
9093 * process.c: Use the same condition for POLL_FOR_INPUT in both
9094 keyboard.c and process.c (bug#1858).
9096 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9098 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9099 (Fgnutls_boot): Use it.
9101 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9103 * doc.c (Fsubstitute_command_keys): Revert last change.
9105 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9107 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9108 quotes the next character, and doesn't affect other longer
9109 sequences (bug#8935).
9111 * lread.c (syms_of_lread): Clarify that is isn't only
9112 `eval-buffer' and `eval-defun' that's affected by
9113 `lexical-binding' (bug#8460).
9115 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9117 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9118 bidi redisplay when a line includes both an image and is truncated.
9120 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9122 Fix minor problems found by static checking.
9123 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9124 (elsz): Now a signed constant, not a size_t var. We prefer signed
9125 types to unsigned, to avoid integer comparison confusion. Without
9126 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9127 "cannot optimize loop, the loop counter may overflow", a symptom
9129 * indent.c (Fvertical_motion): Mark locals as initialized.
9130 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9132 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9134 * search.c (Fre_search_backward): Mention `case-fold-search' in
9135 all the re_search_* functions (bug#8138).

9654 (clone_per_buffer_values): Don't assume that

9695 Random fixes. E.g., (random) never returned negative values.
9696 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9697 subseconds part to the entropy, as that's a bit more random.
9698 Prefer signed to unsigned, since the signedness doesn't matter and
9699 in general we prefer signed. When given a limit, use a
9700 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9701 latter isn't right if USE_2_TAGS_FOR_INTS.
9702 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9703 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9716 This is more efficient than Ffile_directory_p and avoids a minor race.
9718 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9720 * buffer.c (Foverlay_put): Say what the return value is
9723 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9724 is a directory before asking whether to use the file name
9726 (barf_or_query_if_file_exists): Make the "File is a directory"
9727 error be more correct.
9729 * fns.c (Frequire): Remove the mention of the .gz files, since
9730 that's installation-specific, but keep the mention of
9731 `get-load-suffixes'.
9733 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9735 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9746 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9848 * eval.c (struct backtrace): Simplify and port the data structure.
9849 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9850 signed bit field, as this assumption is not portable and it makes
9851 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9852 "char debug_on_exit : 1" as this is not portable either; instead,
9853 use the portable "unsigned int debug_on_exit : 1". Remove unused
9854 member evalargs. Remove obsolete comments about cc bombing out.

10051 Check for size overflow.
10053 * image.c (cache_image): Check for size arithmetic overflow.

10056 (saved_doc_string_size, saved_doc_string_length)
10057 (prev_saved_doc_string_size, prev_saved_doc_string_length):
10058 Now ptrdiff_t, not int.
10059 (read1): Don't assume doc string length fits in int. Check for
10060 out-of-range doc string lengths.
10061 (read_list): Don't assume file position fits in int.
10062 (read_escape): Check for hex character overflow.
10064 2011-06-22 Leo Liu <sdl.web@gmail.com>
10066 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10067 Move to minibuffer.el.
10069 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10071 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10072 The following patches are for when GLYPH_DEBUG && !XASSERT.
10073 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10074 * dispnew.c (flush_stdout):
10075 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10076 Mark as externally visible.
10077 * dispnew.c (check_window_matrix_pointers): Now static.
10078 * dispnew.c (window_to_frame_vpos):
10079 * xfns.c (unwind_create_frame):
10080 * xterm.c (x_check_font): Remove unused local.
10081 * scroll.c (CHECK_BOUNDS):
10082 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10083 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10084 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10085 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10086 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10088 (debug_method_add): Use va_list and vsprintf rather than relying
10089 on undefined behavior with wrong number of arguments.
10090 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10091 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10092 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10093 since we're not interested in debugging glyphs with old libraries.
10094 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10095 GCC 4.6.0's static checking.
10097 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10099 Integer overflow and signedness fixes (Bug#8873).

10108 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10109 (x_create_bitmap_from_xpm_data):
10110 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10111 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10113 * xfaces.c (load_pixmap):
10114 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10115 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10116 (.bitmaps_last, struct x_output.icon_bitmap):
10117 Use ptrdiff_t, not int, for bitmap indexes.
10118 (x_allocate_bitmap_record): Check for size overflow.
10119 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10121 Use ptrdiff_t, not int, for overlay counts.
10122 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10123 * editfns.c (overlays_around, get_pos_property):
10124 * textprop.c (get_char_property_and_overlay):
10125 * xdisp.c (next_overlay_change, note_mouse_highlight):
10126 * xfaces.c (face_at_buffer_position):
10127 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10128 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10129 (Fnext_overlay_change, Fprevious_overlay_change)
10130 (mouse_face_overlay_overlaps, Foverlays_in):
10131 Use ptrdiff_t, not int, for sizes.
10132 (overlays_at, overlays_in): Check for size-calculation overflow.
10134 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10136 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10137 (x_session_initialize): Do not assume string length fits in int.
10139 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10140 This is unlikely, but can occur if DPI is outlandish.
10142 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10143 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10145 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10146 * xrdb.c (magic_file_p, search_magic_path):
10147 Omit last arg SUFFIX; it was always 0. All callers changed.
10148 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10150 * xfont.c (xfont_match): Avoid need for strlen.
10152 * xfns.c: Don't assume strlen fits in int.

10155 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10156 not unsigned long, as we prefer signed integers. All callers changed.
10157 Detect integer overflow in repeat count.
10158 (message_dolog): Don't assume print length fits in 39 bytes.
10159 (display_mode_element): Don't assume strlen fits in int.
10161 * termcap.c: Don't assume sizes fit in int and never overflow.
10162 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10163 (gobble_line): Check for size-calculation overflow.
10165 * minibuf.c (Fread_buffer):
10166 * lread.c (intern, intern_c_string):
10167 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10168 Don't assume string length fits in int.
10170 * keyboard.c (parse_tool_bar_item):
10171 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10173 * font.c: Don't assume string length fits in int.
10174 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10175 Use ptrdiff_t, not int.
10176 (font_intern_prop): Don't assume string length fits in int.
10177 Don't assume integer property fits in fixnum.
10178 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10180 * filelock.c: Fix some buffer overrun and integer overflow issues.
10181 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10182 Reformulate so as not to need the command string.
10183 Invoke gzip -cd rather than gunzip, as it's more portable.
10184 (lock_info_type, lock_file_1, lock_file):
10185 Don't assume pid_t and time_t fit in unsigned long.
10186 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10187 (current_lock_owner): Prefer signed type for sizes.
10188 Use memcpy, not strncpy, where memcpy is what is really wanted.
10189 Don't assume (via atoi) that time_t and pid_t fit in int.
10190 Check for time_t and/or pid_t out of range, e.g., via a network share.
10191 Don't alloca where an auto var works fine.
10193 * fileio.c: Fix some integer overflow issues.
10194 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10195 Don't assume string length fits in int.
10196 (directory_file_name): Don't assume string length fits in long.
10197 (make_temp_name): Don't assume pid fits in int, or that its print
10198 length is less than 20.
10200 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10202 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10204 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10206 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10207 We prefer signed integers, even for size calculations.
10209 * emacs.c: Don't assume string length fits in 'int'.
10210 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10211 (main): Don't invoke strlen when not needed.
10213 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10214 (XD_DEBUG_MESSAGE): Don't waste a byte.
10216 * callproc.c (getenv_internal_1, getenv_internal)
10217 (Fgetenv_internal):
10218 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10220 * lread.c (invalid_syntax): Omit length argument.
10221 All uses changed. This doesn't fix a bug, but it simplifies the
10222 code away from its former Hollerith-constant appearance, and it's
10223 one less 'int' to worry about when looking at integer-overflow issues.
10224 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10226 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10227 This didn't break anything, but it didn't help either.
10228 It's confusing to put a bogus integer in a place where the actual
10229 value does not matter.
10230 (LIST_END_P): Remove unused macro and its bogus comment.
10231 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10233 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10234 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10236 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10237 We prefer signed types, and the value cannot exceed the EMACS_INT
10238 range anyway (because otherwise the length would not be representable).
10239 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10240 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10241 This avoids a GCC warning when WIDE_EMACS_INT.
10243 * indent.c (sane_tab_width): New function.
10244 (current_column, scan_for_column, Findent_to, position_indentation)
10245 (compute_motion): Use it. This is just for clarity.
10246 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10248 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10250 * lisp.h (lint_assume): New macro.
10251 * composite.c (composition_gstring_put_cache):
10252 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10254 * editfns.c, insdel.c:
10255 Omit unnecessary forward decls, to simplify future changes.
10257 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10259 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10261 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10262 Use much-faster test for byte-length change.
10263 Don't assume string byte-length fits in 'int'.
10264 Check that character arg fits in 'int'.
10265 (mapcar1): Declare byte as byte, for clarity.
10267 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10269 * fns.c (concat): Catch string overflow earlier.
10270 Do not rely on integer wraparound.
10272 * dispextern.h (struct it.overlay_strings_charpos)
10273 (struct it.selective): Now EMACS_INT, not int.
10274 * xdisp.c (forward_to_next_line_start)
10275 (back_to_previous_visible_line_start)
10276 (reseat_at_next_visible_line_start, next_element_from_buffer):
10277 Don't arbitrarily truncate the value of 'selective' to int.
10279 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10281 * composite.c: Don't truncate sizes to 'int'.
10282 (composition_gstring_p, composition_reseat_it)
10283 (composition_adjust_point): Use EMACS_INT, not int.
10284 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10285 not EMACS_UINT, for indexes.
10287 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10289 * buffer.c: Include <verify.h>.
10290 (struct sortvec.priority, struct sortstr.priority):
10291 Now EMACS_INT, not int.
10292 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10293 (struct sortstr.size, record_overlay_string)
10294 (struct sortstrlist.size, struct sortlist.used):
10295 Don't truncate size to int.
10296 (record_overlay_string): Check for size-calculation overflow.
10297 (init_buffer_once): Check at compile-time, not run-time.
10299 2011-06-22 Jim Meyering <meyering@redhat.com>
10301 Don't leak an XBM-image-sized buffer
10302 * image.c (xbm_load): Free the image buffer after using it.
10304 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10307 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10308 that Sun C diagnosed.
10309 * fns.c (secure_hash): Fix pointer signedness issue.
10310 * intervals.c (static_offset_intervals): New function.
10311 (offset_intervals): Use it.
10313 2011-06-21 Leo Liu <sdl.web@gmail.com>
10316 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10319 * fns.c (secure_hash): Rename from crypto_hash_function and change
10320 the first arg to accept symbols.
10321 (Fsecure_hash): New primitive.
10322 (syms_of_fns): New symbols.
10324 2011-06-20 Deniz Dogan <deniz@dogan.se>
10326 * process.c (Fset_process_buffer): Clarify return value in
10329 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10331 * dispnew.c (add_window_display_history): Use BVAR.
10333 * xdisp.c (debug_method_add): Use BVAR.
10334 (check_window_end, dump_glyph_matrix, dump_glyph)
10335 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10337 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10340 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10341 check till after the cache is created in init_frame_faces.
10343 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10345 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10347 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10349 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10350 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10351 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10353 Improve buffer-overflow checking (Bug#8873).
10354 * fileio.c (Finsert_file_contents):
10355 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10356 Remove the old (too-loose) buffer overflow checks.
10357 They weren't needed, since make_gap checks for buffer overflow.
10358 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10359 The old code merely checked for Emacs fixnum overflow, and relied
10360 on undefined (wraparound) behavior. The new code avoids undefined
10361 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10363 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10364 Tune. Don't use wider integers than needed. Don't use alloca.
10365 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10367 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10369 * insdel.c, lisp.h (buffer_overflow): New function.
10370 (insert_from_buffer_1, replace_range, replace_range_2):
10371 * insdel.c (make_gap_larger):
10372 * editfns.c (Finsert_char):
10373 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10375 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10377 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10379 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10381 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10382 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10384 * fileio.c: Don't assume EMACS_INT fits in off_t.
10385 (emacs_lseek): New static function.
10386 (Finsert_file_contents, Fwrite_region): Use it.
10387 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10389 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10391 * fns.c: Don't overflow int when computing a list length.
10392 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10393 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10394 truncation on 64-bit hosts. Check for QUIT every
10395 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10396 faster and is responsive enough.
10397 (Flength): Report an error instead of overflowing an integer.
10398 (Fsafe_length): Return a float if the value is not representable
10399 as a fixnum. This shouldn't happen except in contrived situations.
10400 (Fnthcdr, Fsort): Don't assume list length fits in int.
10401 (Fcopy_sequence): Don't assume vector length fits in int.
10403 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10404 (header_size, word_size): New constants.
10405 (allocate_vectorlike): Don't check size overflow here.
10406 (allocate_vector): Check it here instead, since this is the only
10407 caller of allocate_vectorlike that could cause overflow.
10408 Check that the new vector's length is representable as a fixnum.
10410 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10411 The previous code was bogus. For example, next_almost_prime (32)
10412 returned 39, which is undesirable as it is a multiple of 3; and
10413 next_almost_prime (24) returned 25, which is a multiple of 5 so
10414 why was the code bothering to check for multiples of 7?
10416 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10418 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10420 Variadic C functions now count arguments with ptrdiff_t.
10421 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10422 Back then I didn't know that the Emacs coding style prefers signed int.
10423 Also, in the meantime I found a few more instances where arguments
10424 were being counted with int, which may truncate counts on 64-bit
10425 machines, or EMACS_INT, which may be unnecessarily wide.
10426 * lisp.h (struct Lisp_Subr.function.aMANY)
10427 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10428 Arg counts are now ptrdiff_t, not size_t.
10429 All variadic functions and their callers changed accordingly.
10430 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10431 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10432 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10433 * callint.c (Fcall_interactively): Check arg count for overflow,
10434 to avoid potential buffer overrun. Use signed char, not 'int',
10435 for 'varies' array, so that we needn't bother to check its size
10436 calculation for overflow.
10437 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10438 * eval.c (apply_lambda):
10439 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10440 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10441 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10443 * callint.c (Fcall_interactively): Don't use index var as event count.
10445 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10446 * mem-limits.h (SIZE): Remove; no longer used.
10448 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10450 Remove unnecessary casts.
10451 * xterm.c (x_term_init):
10452 * xfns.c (x_set_border_pixel):
10453 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10454 These aren't needed now that we assume ANSI C.
10456 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10457 It's more likely to cause problems (due to unsigned overflow)
10460 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10462 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10464 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10466 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10468 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10470 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10472 GLYPH_CODE_FACE returns EMACS_INT, not int.
10473 * dispextern.h (merge_faces):
10474 * xfaces.c (merge_faces):
10475 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10476 Don't assume EMACS_INT fits in int.
10478 * character.h (CHAR_VALID_P): Remove unused parameter.
10479 * fontset.c, lisp.h, xdisp.c: All uses changed.
10481 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10483 * fns.c (concat): Minor tuning based on overflow analysis.
10484 This doesn't fix any bugs. Use int to hold character, instead
10485 of constantly refetching from Emacs object. Use XFASTINT, not
10486 XINT, for value known to be a character. Don't bother comparing
10487 a single byte to 0400, as it's always less.
10489 * floatfns.c (Fexpt):
10490 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10492 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10495 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10497 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10498 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10499 incorrectly succeed when S was a string, because 4294967386 was
10500 truncated before it was used.
10502 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10503 Otherwise, an out-of-range integer could cause undefined behavior
10506 * composite.c: Use int, not EMACS_INT, for characters.
10507 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10508 EMACS_INT, for values that are known to be in character range.
10509 This doesn't fix any bugs but is the usual style inside Emacs and
10510 may generate better code on 32-bit machines.
10512 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10513 This is for reasons similar to the recent CHAR_STRING fix.
10514 * charset.c (Fencode_char): Check that character arg is actually
10515 a character. Pass an int to ENCODE_CHAR.
10516 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10517 wider than 'int', as a compile-time check to prevent future regressions
10520 * character.c (char_string): Remove unnecessary casts.
10522 Make sure a 64-bit char is never passed to CHAR_STRING.
10523 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10524 by silently ignoring the top 32 bits, allowing some values
10525 that were far too large to be valid characters.
10526 * character.h: Include <verify.h>.
10527 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10528 arguments are no wider than unsigned, as a compile-time check
10529 to prevent future regressions in this area.
10531 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10532 (Fsubst_char_in_region):
10534 * xdisp.c (decode_mode_spec_coding):
10535 Adjust to CHAR_STRING's new requirement.
10536 * editfns.c (Finsert_char, Fsubst_char_in_region):
10537 * fns.c (concat): Check that character args are actually
10538 characters. Without this test, these functions did the wrong
10539 thing with wildly out-of-range values on 64-bit hosts.
10541 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10542 These casts should not be needed on 32-bit hosts, either.
10543 * keyboard.c (read_char):
10544 * lread.c (Fload): Remove casts to unsigned.
10546 * lisp.h (UNSIGNED_CMP): New macro.
10547 This fixes comparison bugs on 64-bit hosts.
10548 (ASCII_CHAR_P): Use it.
10549 * casefiddle.c (casify_object):
10550 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10551 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10552 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10553 * dispextern.h (FACE_FROM_ID):
10554 * keyboard.c (read_char): Use UNSIGNED_CMP.
10556 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10557 not to EMACS_INT, to avoid GCC warning.
10559 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10561 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10562 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10563 isn't needed on 32-bit machines.
10565 * buffer.c (Fgenerate_new_buffer_name):
10566 Use EMACS_INT for count, not int.
10567 (advance_to_char_boundary): Return EMACS_INT, not int.
10569 * data.c (Qcompiled_function): Now static.
10571 * window.c (window_body_lines): Now static.
10573 * image.c (gif_load): Rename local to avoid shadowing.
10575 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10576 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10577 * alloc.c (make_save_value): Integer argument is now of type
10578 ptrdiff_t, not int.
10579 (mark_object): Use ptrdiff_t, not int.
10580 * lisp.h (pD): New macro.
10581 * print.c (print_object): Use it.
10583 * alloc.c: Use EMACS_INT, not int, to count objects.
10584 (total_conses, total_markers, total_symbols, total_vector_size)
10585 (total_free_conses, total_free_markers, total_free_symbols)
10586 (total_free_floats, total_floats, total_free_intervals)
10587 (total_intervals, total_strings, total_free_strings):
10588 Now EMACS_INT, not int. All uses changed.
10589 (Fgarbage_collect): Compute overall total using a double, so that
10590 integer overflow is less likely to be a problem. Check for overflow
10591 when converting back to an integer.
10592 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10593 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10594 These were 'int' variables that could overflow on 64-bit hosts;
10595 they were never used, so remove them instead of repairing them.
10596 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10597 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10598 Previously, this ceilinged at INT_MAX, but that doesn't work on
10600 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10602 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10603 (allocate_vectorlike): Check for ptrdiff_t overflow.
10604 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10605 when a (possibly-narrower) signed value would do just as well.
10606 We prefer using signed arithmetic, to avoid comparison confusion.
10608 * alloc.c: Catch some string size overflows that we were missing.
10609 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10610 for convenience in STRING_BYTES_MAX.
10611 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10612 The definition here is exact; the one in lisp.h was approximate.
10613 (allocate_string_data): Check for string overflow. This catches
10614 some instances we weren't catching before. Also, it catches
10615 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10616 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10617 and ptrdiff_t and EMACS_INT are both 64 bits.
10619 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10620 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10621 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10623 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10625 * alloc.c (Fmake_string): Check for out-of-range init.
10627 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10629 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10631 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10633 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

10646 (update_theme_scrollbar_width): New function.
10647 (xg_get_default_scrollbar_width): Move code to
10648 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

10651 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10653 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

10660 * window.c (temp_output_buffer_show): Call display_buffer with
10661 second argument Vtemp_buffer_show_specifiers and reset latter
10662 immediately after the call.

11216 (display_prop_intangible_p): Reimplement to call
11217 handle_display_spec instead of single_display_spec_intangible_p.

11229 value of a `display' property is a "replacing spec".
11230 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11231 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11261 * gnutls.c: Use Emacs's memory allocators.
11262 Without this change, the gnutls library would invoke malloc etc.
11263 directly, which causes problems on non-SYNC_INPUT hosts, and which
11264 runs afoul of improving memory_full behavior. (Bug#8761)
11265 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11266 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11267 xfree instead of the default malloc, realloc, free.
11268 (Fgnutls_boot): No need to check for memory allocation failure,
11269 since xmalloc does that for us.

11298 need to be updated by these changes.
11299 * fns.c (make_hash_table, maybe_resize_hash_table):
11300 Check for integer overflow with large hash tables.
11301 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11302 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11303 (SXHASH_REDUCE): New macro.
11304 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11305 Use it instead of discarding useful hash info with large hash values.
11306 (sxhash_float): New function.
11307 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11308 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11309 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11310 Rewrite to use FIXNUM_BITS, as this simplifies things.
11311 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11312 Adjust signatures to match updated version of code.
11313 (consing_since_gc): Now EMACS_INT, since a single hash table can
11314 use more than INT_MAX bytes.

11355 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11356 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11357 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11358 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11359 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11361 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11363 Make it possible to run ./temacs.
11365 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11366 syms_of_callproc does the same thing. Remove test for
11367 "initialized", do it in the caller.
11368 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11370 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11372 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11373 (read_minibuf): Use get_minibuffer.
11374 (syms_of_minibuf): Use DEFSYM.
11375 (Qmetadata): New var.
11376 * data.c (Qbuffer): Don't make it static.
11377 (syms_of_data): Use DEFSYM.
11379 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11381 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11382 (CCL_CODE_MIN): New macro.
11384 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11386 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11388 * eval.c (Qdebug): Now static.
11389 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11390 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11391 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11393 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11395 * image.c: Various fixes to ImageMagick code comments.
11396 (Fimagemagick_types): Doc fix.
11398 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11400 Minor fixes prompted by GCC 4.6.0 warnings.
11402 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11404 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11405 (x_clipboard_manager_save_all): Move extern decl to ...
11406 * xterm.h: ... here, so that it can be checked for consistency.
11408 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11410 * xselect.c (x_clipboard_manager_save_frame)
11411 (x_clipboard_manager_save_all): New functions.
11412 (Fx_clipboard_manager_save): Lisp function deleted.
11414 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11415 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11417 * xterm.h: Update prototype.
11419 2011-05-28 William Xu <william.xwl@gmail.com>
11421 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11422 exiting (Bug#8239).
11424 2011-05-28 Jim Meyering <meyering@redhat.com>
11426 Avoid a sign-extension bug in crypto_hash_function.
11427 * fns.c (to_uchar): Define.
11428 (crypto_hash_function): Use it to convert some newly-signed
11429 variables to unsigned, to avoid sign-extension bugs. For example,
11430 without this change, (md5 "truc") would evaluate to
11431 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11432 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11433 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11435 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11437 Integer overflow fixes.
11439 * dbusbind.c: Serial number integer overflow fixes.
11440 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11441 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11442 to hold a serial number that is too large for a fixnum.
11443 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11444 Check for serial numbers out of range. Decode any serial number
11445 that was so large that it became a float. (Bug#8722)
11447 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11448 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11449 Use XFASTINT rather than XUINT when numbers are nonnegative.
11450 (xd_append_arg, Fdbus_method_return_internal):
11451 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11452 arguments, check that Lisp number is nonnegative, rather than
11453 silently wrapping negative numbers around. (Bug#8722)
11454 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11457 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11459 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11461 ccl: Add integer overflow checks.
11462 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11463 (IN_INT_RANGE): New macros.
11464 (ccl_driver): Use them to check for integer overflow when
11465 decoding a CCL program. Many of the new checks are whether XINT (x)
11466 fits in int; it doesn't always, on 64-bit hosts. The new version
11467 doesn't catch all possible integer overflows, but it's an
11468 improvement. (Bug#8719)
11470 * alloc.c (make_event_array): Use XINT, not XUINT.
11471 There's no need for unsigned here.
11473 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11474 This follows up to the 2011-05-06 change that substituted uintptr_t
11475 for EMACS_INT. This case wasn't caught back then.
11477 Rework Fformat to avoid integer overflow issues.
11478 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11479 now (part of C89). Include <verify.h>.
11480 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11481 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11482 (Fformat): Avoid the prepass trying to compute sizes; it was only
11483 approximate and thus did not catch overflow reliably. Instead, walk
11484 through the format just once, formatting and computing sizes as we go,
11485 checking for integer overflow at every step, and allocating a larger
11486 buffer as needed. Keep track separately whether the format is
11487 multibyte. Keep only the most-recently calculated precision, rather
11488 than them all. Record whether each argument has been converted to
11489 string. Use EMACS_INT, not int, for byte and char and arg counts.
11490 Support field widths and precisions larger than INT_MAX. Avoid
11491 sprintf's undefined behavior with conversion specifications such as %#d
11492 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11493 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11494 formatting out-of-range floating point numbers with int
11495 formats. (Bug#8668)
11497 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11499 * data.c: Avoid integer truncation in expressions involving floats.
11500 * data.c: Include <intprops.h>.
11501 (arith_driver): When there's an integer overflow in an expression
11502 involving floating point, convert the integers to floating point
11503 so that the resulting value does not suffer from catastrophic
11504 integer truncation. For example, on a 64-bit host (* 4
11505 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11506 Do not rely on undefined behavior after integer overflow.
11508 merge count_size_as_multibyte, parse_str_to_multibyte
11509 * character.c, character.h (count_size_as_multibyte):
11510 Rename from parse_str_to_multibyte; all uses changed.
11511 Check for integer overflow.
11512 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11513 since it's now a duplicate of the other. This is more of
11514 a character than a buffer op, so better that it's in character.c.
11515 * fns.c, print.c: Adjust to above changes.
11517 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11519 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11521 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11523 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11524 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11525 (x_clipboard_manager_save): Now static.
11526 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11528 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11529 (crypto_hash_function): Now static.
11530 Fix pointer signedness problems. Avoid unnecessary initializations.
11532 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11534 * termhooks.h (Vselection_alist): Make it terminal-local.
11536 * terminal.c (create_terminal): Initialize it.
11538 * xselect.c: Support for clipboard managers.
11539 (Vselection_alist): Move to termhooks.h as terminal-local var.
11540 (LOCAL_SELECTION): New macro.
11541 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11542 (symbol_to_x_atom): Remove gratuitous arg.
11543 (x_handle_selection_request, lisp_data_to_selection_data)
11544 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11545 (x_own_selection, x_get_local_selection, x_convert_selection):
11546 New arg, specifying work frame. Use terminal-local Vselection_alist.
11547 (some_frame_on_display): Delete unused function.
11548 (Fx_own_selection_internal, Fx_get_selection_internal)
11549 (Fx_disown_selection_internal, Fx_selection_owner_p)
11550 (Fx_selection_exists_p): New optional frame arg.
11551 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11552 (x_handle_selection_clear): Don't treat other terminals with the
11553 same keyboard specially. Use the terminal-local Vselection_alist.
11554 (x_clear_frame_selections): Use Frun_hook_with_args.
11556 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11558 * xterm.h: Add support for those atoms.
11560 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11562 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11563 (converted_selections, conversion_fail_tag): New global variables.
11564 (x_selection_request_lisp_error): Free the above.
11565 (x_get_local_selection): Remove unnecessary code.
11566 (x_reply_selection_request): Args changed; handle arbitrary array
11567 of converted selections stored in converted_selections.
11568 Separate the XChangeProperty and SelectionNotify steps.
11569 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11570 (x_convert_selection): New function.
11571 (x_handle_selection_event): Simplify.
11572 (x_get_foreign_selection): Don't ignore incoming requests while
11573 waiting for an answer; this will fail when we implement
11574 SAVE_TARGETS, and seems unnecessary anyway.
11575 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11576 (Vx_sent_selection_functions): Doc fix.
11578 2011-05-26 Leo Liu <sdl.web@gmail.com>
11580 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11582 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11584 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11586 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11587 for fringe update if it has periodic bitmap.
11588 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11589 and fringe_bitmap_periodic_p.
11591 * fringe.c (get_fringe_bitmap_data): New function.
11592 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11593 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11594 row. Mark glyph row for fringe update if periodicity changed.
11596 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11597 for fringe update unless it has periodic bitmap.
11599 2011-05-25 Kenichi Handa <handa@m17n.org>
11601 * xdisp.c (get_next_display_element): Set correct it->face_id for
11602 a static composition.
11604 2011-05-24 Leo Liu <sdl.web@gmail.com>
11607 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11609 * fns.c (crypto_hash_function, Fsha1): New function.
11610 (Fmd5): Use crypto_hash_function.
11611 (syms_of_fns): Add Ssha1.
11613 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11615 * gnutls.c: Remove unused macros.
11616 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11617 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11618 Remove macros that are defined and never used.
11619 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11621 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11623 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11624 (Fx_get_selection_internal): Minor cleanup.
11625 (Fx_own_selection_internal): Rename arguments for consistency with
11628 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11630 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11632 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11634 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11636 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11638 * dispnew.c (scrolling_window): Don't exclude the case that the
11639 last enabled row in the desired matrix touches the bottom boundary.
11641 2011-05-21 Glenn Morris <rgm@gnu.org>
11643 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11644 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11645 and add some more files.
11647 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11649 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11650 report_file_error introduced by the change from 2011-05-07.
11652 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11654 * systime.h (Time): Define only if emacs is defined.
11655 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11656 where the include path doesn't have X11/X.h by default. See
11657 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11659 2011-05-20 Kenichi Handa <handa@m17n.org>
11661 * composite.c (find_automatic_composition): Fix previous change.
11663 2011-05-20 Glenn Morris <rgm@gnu.org>
11665 * lisp.mk: New file, split from Makefile.in.
11666 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11667 (shortlisp): Remove.
11668 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11670 2011-05-19 Glenn Morris <rgm@gnu.org>
11672 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11673 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11674 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11675 (lisp): Set the order to that of loadup.el.
11676 (shortlisp): Make it a copy of $lisp.
11677 (SOME_MACHINE_LISP): Remove.
11678 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11679 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11681 2011-05-18 Kenichi Handa <handa@m17n.org>
11683 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11684 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11685 (find_automatic_composition): Mostly rewrite for efficiency.
11687 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11689 * makefile.w32-in: Update dependencies.
11691 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11693 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11694 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11696 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11698 Fix some integer overflow issues, such as string length overflow.
11700 * insdel.c (count_size_as_multibyte): Check for string overflow.
11702 * character.c (lisp_string_width): Check for string overflow.
11703 Use EMACS_INT, not int, for string indexes and lengths; in
11704 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11705 the resulting string length overflows an EMACS_INT; instead,
11706 report a string overflow if no precision given. When checking for
11707 precision exhaustion, use a check that cannot possibly have
11708 integer overflow. (Bug#8675)
11709 * character.h (lisp_string_width): Adjust to new signature.
11711 * alloc.c (string_overflow): New function.
11712 (Fmake_string): Use it. This doesn't change behavior, but saves
11713 a few bytes and will simplify future changes.
11714 * character.c (string_escape_byte8): Likewise.
11715 * lisp.h (string_overflow): New decl.
11717 Fixups, following up to the user-interface timestamp change.
11718 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11719 for UI timestamps, instead of unsigned long.
11720 * msdos.c (mouse_get_pos): Likewise.
11721 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11722 * w32gui.h (Time): Define by including "systime.h" rather than by
11723 declaring it ourselves. (Bug#8664)
11725 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11726 * image.c (clear_image_cache): Likewise.
11728 * term.c (term_mouse_position): Don't assume time_t wraparound.
11730 Be more systematic about user-interface timestamps.
11731 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11732 and sometimes 'EMACS_UINT', to represent these timestamps.
11733 This change causes it to use 'Time' uniformly, as that's what X uses.
11734 This makes the code easier to follow, and makes it easier to catch
11735 integer overflow bugs such as Bug#8664.
11736 * frame.c (Fmouse_position, Fmouse_pixel_position):
11737 Use Time, not unsigned long, for user-interface timestamps.
11738 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11739 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11740 * keyboard.h (last_event_timestamp): Likewise.
11741 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11742 * menu.h (xmenu_show): Likewise.
11743 * term.c (term_mouse_position): Likewise.
11744 * termhooks.h (struct input_event.timestamp): Likewise.
11745 (struct terminal.mouse_position_hook): Likewise.
11746 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11747 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11748 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11749 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11750 what it was before.
11751 * menu.h, termhooks.h: Include "systime.h", for Time.
11753 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11754 Don't assume that the difference between two unsigned long values
11755 can fit into an integer. At this point, we know button_down_time
11756 <= event->timestamp, so the difference must be nonnegative, so
11757 there's no need to cast the result if double-click-time is
11758 nonnegative, as it should be; check that it's nonnegative, just in
11759 case. This bug is triggered when events are more than 2**31 ms
11760 apart (about 25 days). (Bug#8664)
11762 * xselect.c (last_event_timestamp): Remove duplicate decl.
11763 (x_own_selection): Remove needless cast to unsigned long.
11765 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11766 that always fit in int. Use a sentinel instead of a counter, to
11767 avoid a temp and to allay GCC's concerns about possible int overflow.
11768 * frame.h (struct frame): Use int for menu_bar_items_used
11769 instead of EMACS_INT, since it always fits in int.
11771 * menu.c (grow_menu_items): Check for int overflow.
11773 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11775 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11776 Before, the code was not consistent. These values cannot exceed
11777 2**31 - 1 so there's no need to make them unsigned.
11778 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11779 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11780 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11782 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11784 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11785 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11786 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11787 presumably because the widths might not match.
11789 * window.c (size_window): Avoid needless test at loop start.
11791 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11793 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11795 2011-05-12 Drew Adams <drew.adams@oracle.com>
11797 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11799 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11801 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11802 `width' to `bar_area_x' and `bar_area_width', respectively.
11803 (x_scroll_run): Take account of fringe background extension.
11805 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11806 Rename local vars `left' and `width' to `bar_area_x' and
11807 `bar_area_width', respectively.
11808 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11809 background extension.
11811 2011-05-10 Jim Meyering <meyering@redhat.com>
11813 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11815 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11817 * image.c (Finit_image_library): Return t for built-in image types,
11818 like pbm and xbm. (Bug#8640)
11820 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11822 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11824 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11826 * w32console.c (Fset_screen_color): Doc fix.
11827 (Fget_screen_color): New function.
11828 (syms_of_ntterm): Defsubr it.
11830 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11831 unlink the temporary file if Fcall_process didn't create it in the
11833 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11834 child process will be redirected to a file specified with `:file'.
11835 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11836 cue to call_process_cleanup not to close that handle.
11838 2011-05-07 Ben Key <bkey76@gmail.com>
11840 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11841 one of two shell specific rules, either bootstrap-temacs-CMD or
11842 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11843 to the previous implementation of the bootstrap-temacs rule.
11844 The bootstrap-temacs-CMD rule is similar to the previous
11845 implementation of the bootstrap-temacs rule except that it
11846 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11849 These changes, along with some changes to nt/configure.bat,
11850 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11851 earlier fix to add support for --cflags and --ldflags options
11852 that include quotes so that it works whether make uses cmd or
11855 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11857 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11858 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11860 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11861 a string. Handle both cases.
11862 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11863 (Fdbus_register_method): Use Qinvalid_function.
11865 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11867 * makefile.w32-in: Update dependencies.
11868 (LISP_H): Add inttypes.h and stdin.h.
11869 (PROCESS_H): Add unistd.h.
11871 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11873 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11874 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11876 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11878 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11880 * term.c (vfatal): Remove stray call to va_end.
11881 It's not needed and the C Standard doesn't allow it here anyway.
11883 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11884 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11886 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11889 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11891 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11893 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11895 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11897 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11899 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11900 * charset.c (Fdefine_charset_internal): Don't initialize
11901 charset.code_space[15]. The value was garbage, on hosts with
11902 32-bit int (Bug#8600).
11904 * lread.c (read_integer): Be more consistent with string-to-number.
11905 Use string_to_number to do the actual conversion; this avoids
11906 rounding errors and fixes some other screwups. Without this fix,
11907 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11908 (digit_to_number): Move earlier, for benefit of read_integer.
11909 Return -1 if the digit is out of range for the base, -2 if it is
11910 not a digit in any supported base. (Bug#8602)
11912 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11914 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11915 to match comment at start of function. This also removes a
11916 GCC warning about overflow in a 32+64-bit port.
11918 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11920 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11921 Reported by Stefan Monnier in
11922 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11923 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11924 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11926 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11927 (EMACS_UINTPTR): Likewise, with uintptr_t.
11929 * lisp.h: Prefer 64-bit EMACS_INT if available.
11930 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11931 on 32-bit hosts that have 64-bit int, so that they can access
11933 However, temporarily disable this change unless the temporary
11934 symbol WIDE_EMACS_INT is defined.
11936 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11938 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11939 This removes an assumption that EMACS_INT and long are the same
11940 width as pointers. The assumption is true for Emacs porting targets
11941 now, but we want to make other targets possible.
11942 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11943 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11944 In the rest of the code, change types of integers that hold casted
11945 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11946 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11947 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11948 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11949 No need to cast type when ORing.
11950 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11951 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11952 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11953 assume EMACS_INT is the same width as char *.
11954 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11955 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11956 Remove no-longer-needed casts.
11957 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11958 (xg_tool_bar_help_callback, xg_make_tool_item):
11959 Use EMACS_INTPTR to hold an integer
11960 that will be cast to void *; this can avoid a GCC warning
11961 if EMACS_INT is not the same width as void *.
11962 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11963 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11964 (current_message_1, set_message_1):
11965 Use a local to convert to proper width without a cast.
11966 * xmenu.c (dialog_selection_callback): Likewise.
11968 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11969 Also, don't assume VALBITS / RAND_BITS is less than 5,
11970 and don't rely on undefined behavior when shifting a 1 left into
11972 * lisp.h (get_random): Change signature to match.
11974 * lread.c (hash_string): Use size_t, not int, for hash computation.
11975 Normally we prefer signed values; but hashing is special, because
11976 it's better to use unsigned division on hash table sizes so that
11977 the remainder is nonnegative. Also, size_t is the natural width
11978 for hashing into memory. The previous code used 'int', which doesn't
11979 retain enough info to hash well into very large tables.
11980 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11982 * dbusbind.c: Don't possibly lose pointer info when converting.
11983 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11984 Use XPNTR rather than XHASH, so that the high-order bits of
11985 the pointer aren't lost when converting through void *.
11987 * eval.c (Fautoload): Don't double-shift a pointer.
11989 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11991 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11993 * gnutls.c (DEF_GNUTLS_FN):
11994 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11996 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11998 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12001 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12003 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12004 New version that can reserve upto 2GB of heap space.
12006 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12008 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

12015 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12017 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12018 Update dependencies.
12020 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12022 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12023 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12024 Remove unused parameter `fildes'.
12025 * process.c (read_process_output, send_process): Don't pass it.
12027 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12029 Fix previous change: the library cache is defined in w32.c.
12030 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12031 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12033 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12035 Implement dynamic loading of GnuTLS on Windows.
12037 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12038 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12039 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12042 * gnutls.c (Qgnutls_dll): Define.
12043 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12044 (gnutls_*): Declare function pointers.

12048 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12049 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12050 (emacs_gnutls_write, emacs_gnutls_read)
12051 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12052 (Fgnutls_available_p): New function.
12053 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

12063 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12065 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12066 (w32_delayed_load): Move from image.c. When loading a library, record
12067 its filename in the :loaded-from property of the library id.
12068 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12069 Initialize and staticpro them.
12070 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.

12073 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12074 instead of gnutls_record_check_pending.
12076 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12078 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12080 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12081 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12084 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12086 * xterm.c (x_set_frame_alpha): Do not set property on anything

12109 * sysdep.c (wait_for_termination_1): Make static.
12110 (wait_for_termination, interruptible_wait_for_termination):
12111 Move after wait_for_termination_1.
12113 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12115 * sysdep.c (interruptible_wait_for_termination): New function
12116 which is like wait_for_termination, but allows keyboard
12119 * callproc.c (Fcall_process): Add (:file "file") as an option for
12121 (Fcall_process_region): Ditto.
12123 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12125 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12126 rather than `XVECTOR (FOO)->size'.
12128 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12129 inttypes.h, as a gnulib replacement is used if it not available in
12132 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12134 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12135 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12136 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12138 * coding.c (coding_alloc_by_realloc): Error out if destination
12139 will grow beyond MOST_POSITIVE_FIXNUM.
12140 (decode_coding_emacs_mule): Abort if there isn't enough place in

12153 * window.c (window_scroll_line_based): Use a marker instead of
12154 simple variables to record original value of point. (Bug#7952)
12156 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12157 produced by %s or %c overflows available buffer space. (Bug#8545)
12159 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12161 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

12196 Improve `doprnt' and its usage. (Bug#8545)
12197 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12198 `format_end'. Remove support for %l as a conversion specifier.
12199 Don't use xrealloc. Improve diagnostics when the %l size modifier
12200 is used. Update the commentary.
12202 * eval.c (verror): Simplify calculation of size_t.
12204 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12207 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12209 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12212 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12214 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12215 This makes this file independent of the recent pseudovector change.
12217 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12219 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12221 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12222 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12223 Remove unused local.
12224 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12226 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12227 GCC 4.6.0 optimizes based on type-based alias analysis.
12228 For example, if b is of type struct buffer * and v of type struct
12229 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12230 != &v->size, and therefore "v->size = 1; b->size = 2; return
12231 v->size;" must therefore return 1. This assumption is incorrect
12232 for Emacs, since it type-puns struct Lisp_Vector * with many other
12233 types. To fix this problem, this patch adds a new type struct
12234 vectorlike_header that documents the constraints on layout of vectors
12235 and pseudovectors, and helps optimizing compilers not get fooled
12236 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12237 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12238 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12240 (XSETPVECTYPE): Rewrite in terms of new macro.
12241 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12242 This is a bit clearer, and further avoids the possibility of
12243 undesirable aliasing.
12244 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12245 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12246 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12247 since Lisp_Subr is a special case (no "next" field).
12248 (ASIZE): Now uses header.size rather than size.
12249 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12250 to avoid the hassle of writing XVECTOR (foo)->header.size.
12251 (struct vectorlike_header): New type.
12252 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12253 object, to help avoid aliasing.
12254 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12255 (SUBRP): Likewise, since Lisp_Subr is a special case.
12256 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12257 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12258 (struct Lisp_Hash_Table): Combine first two members into a single
12259 struct vectorlike_header member. All uses of "size" and "next" members
12260 changed to be "header.size" and "header.next".
12261 * buffer.h (struct buffer): Likewise.
12262 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12263 * frame.h (struct frame): Likewise.
12264 * process.h (struct Lisp_Process): Likewise.
12265 * termhooks.h (struct terminal): Likewise.
12266 * window.c (struct save_window_data, struct saved_window): Likewise.
12267 * window.h (struct window): Likewise.
12268 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12269 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12270 * buffer.c (init_buffer_once): Likewise.
12271 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12273 * process.c (Fformat_network_address): Use local var for size,
12276 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12278 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12279 * data.c (atof): Remove decl; no longer used or needed.
12280 (digit_to_number): Move to lread.c.
12281 (Fstring_to_number): Use new string_to_number function, to be
12282 consistent with how the Lisp reader treats infinities and NaNs.
12283 Do not assume that floating-point numbers represent EMACS_INT
12284 without losing information; this is not true on most 64-bit hosts.
12285 Avoid double-rounding errors, by insisting on integers when
12286 parsing non-base-10 numbers, as the documentation specifies.
12287 * lisp.h (string_to_number): New decl, replacing ...
12288 (isfloat_string): Remove.
12289 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12290 (read1): Do not accept +. and -. as integers; this
12291 appears to have been a coding error. Similarly, do not accept
12292 strings like +-1e0 as floating point numbers. Do not report
12293 overflow for integer overflows unless the base is not 10 which
12294 means we have no simple and reliable way to continue.
12295 Break out the floating-point parsing into a new
12296 function string_to_number, so that Fstring_to_number parses
12297 floating point numbers consistently with the Lisp reader.
12298 (digit_to_number): Move here from data.c. Make it static inline.
12299 (E_CHAR, EXP_INT): Remove, replacing with ...
12300 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12301 (string_to_number): New function, replacing isfloat_string.
12302 This function checks for valid syntax and produces the resulting
12303 Lisp float number too. Rework it so that string-to-number
12304 no longer mishandles examples like "1.0e+". Use strtoumax,
12305 so that overflow for non-base-10 numbers is reported only when
12306 there's no portable and simple way to convert to floating point.
12308 * textprop.c (set_text_properties_1): Rewrite for clarity,
12309 and to avoid GCC warning about integer overflow.
12311 * intervals.h (struct interval): Use EMACS_INT for members
12312 where EMACS_UINT might cause problems. See
12313 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12314 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12315 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12317 (offset_intervals): Tell GCC not to worry about length overflow
12318 when negating a negative length.
12320 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12321 (overrun_check_free): Likewise.
12323 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12324 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12327 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12328 (gnutls_make_error): Rename local to avoid shadowing.
12329 (gnutls_emacs_global_deinit): ifdef out; not used.
12330 (Fgnutls_boot): Use const for pointer to readonly storage.
12331 Comment out unused local. Fix pointer signedness problems.
12333 * lread.c (openp): Don't stuff size_t into an 'int'.
12334 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12335 about possible signed overflow.
12337 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12338 (GDK_KEY_g): Don't define if already defined.
12339 (xg_prepare_tooltip): Avoid pointer signedness problem.
12340 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12342 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12343 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12345 * xfns.c (Fx_window_property): Simplify a bit,
12346 to make a bit faster and to avoid GCC 4.6.0 warning.
12347 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12349 * fns.c (internal_equal): Don't assume size_t fits in int.
12351 * alloc.c (compact_small_strings): Tighten assertion a little.
12353 Replace pEd with more-general pI, and fix some printf arg casts.
12354 * lisp.h (pI): New macro, generalizing old pEd macro to other
12355 conversion specifiers. For example, use "...%"pI"d..." rather
12356 than "...%"pEd"...".
12357 (pEd): Remove. All uses replaced with similar uses of pI.
12358 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12359 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12360 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12361 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12362 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12363 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12364 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12366 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12367 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12368 * print.c (safe_debug_print, print_object): Likewise.
12369 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12371 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12372 avoiding the 0 flag, which is not portable.
12373 * process.c (Fmake_network_process): Use pI to avoid cast.
12374 * region-cache.c (pp_cache): Likewise.
12375 * xdisp.c (decode_mode_spec): Likewise.
12376 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12377 behavior on 64-bit hosts with printf arg.
12378 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12379 (x_stop_queuing_selection_requests): Likewise.
12380 (x_get_window_property): Don't truncate byte count to an 'int'
12383 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12384 here, since it parses constructs like leading '-' and spaces,
12385 which are not wanted; and it overflows with large numbers.
12386 Instead, simply match F[0-9]+, which is what is wanted anyway.
12388 * alloc.c: Remove unportable assumptions about struct layout.
12389 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12390 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12391 (allocate_vectorlike, make_pure_vector): Use the new macros,
12392 plus offsetof, to remove unportable assumptions about struct layout.
12393 These assumptions hold on all porting targets that I know of, but
12394 they are not guaranteed, they're easy to remove, and removing them
12395 makes further changes easier.
12397 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12398 This doesn't fix a bug but makes the code clearer.
12399 (string_overrun_cookie): Now const. Use initializers that
12400 don't formally overflow signed char, to avoid warnings.
12401 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12402 can cause Emacs to crash when string overrun checking is enabled.
12403 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12404 multiple of sizeof (EMACS_INT); it need not be, if
12405 alignof(EMACS_INT) < sizeof (EMACS_INT).
12406 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12408 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12415 supposed to be handshaking. (Bug#8556)
12416 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12418 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

12428 * alloc.c (check_sblock, check_string_bytes)
12429 (check_string_free_list): Convert to standard C.
12431 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12433 * w32.c (emacs_gnutls_push): Fix typo.
12435 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12437 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12438 "cast to pointer from integer of different size".
12440 Improve doprnt and its use in verror. (Bug#8545)
12441 * doprnt.c (doprnt): Document the set of format control sequences
12442 supported by the function. Use SAFE_ALLOCA instead of always
12445 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12446 is one byte too soon. Don't use xrealloc; instead xfree and
12449 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12451 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12454 * gnutls.c: Renamed global_initialized to
12455 gnutls_global_initialized. Added internals for the
12456 :verify-hostname-error, :verify-error, and :verify-flags
12457 parameters of `gnutls-boot' and documented those parameters in the
12458 docstring. Start callback support.
12459 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12460 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12461 on error. Return error code.

12463 (emacs_gnutls_read): Likewise.
12464 (Fgnutls_boot): Return handshake error code.

12533 * doprnt.c: Include limits.h.
12534 (SIZE_MAX): New macro.
12535 (doprnt): Return a size_t value. 2nd arg is now size_t.
12536 Many local variables are now size_t instead of int or unsigned.
12537 Improve overflow protection. Support `l' modifier for integer
12538 conversions. Support %l conversion. Don't assume an EMACS_INT
12539 argument for integer conversions and for %c.
12541 * lisp.h (doprnt): Restore prototype.
12543 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12544 $(SRC)/character.h.
12546 * Makefile.in (base_obj): Add back doprnt.o.
12548 * deps.mk (doprnt.o): Add back prerequisites.
12549 (callint.o): Depend on character.h.
12551 * eval.c (internal_lisp_condition_case): Include the handler
12552 representation in the error message.
12553 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12554 when breaking from the loop.
12556 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12558 * callint.c (Fcall_interactively): When displaying error message
12559 about invalid control letter, pass the character's codepoint, not
12560 a pointer to its multibyte form. Improve display of the character
12561 in octal and display also its hex code.
12563 * character.c (char_string): Use %x to display the (unsigned)
12564 codepoint of an invalid character, to avoid displaying a bogus
12567 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12568 `error', not SYMBOL_NAME itself.
12570 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12571 character arguments to `error'.
12573 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12574 to `error' in error message about FINAL_CHAR argument. Make sure
12575 FINAL_CHAR is a character, and use %c when it is passed as
12576 argument to `error'.

12640 Define only if needed.
12642 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
12643 by pacifying GCC about it. Maybe it's time to retire it?
12644 * xfaces.c (USG, __TIMEVAL__): Likewise.
12646 * dispextern.h (struct redisplay_interface): Rename param
12647 to avoid shadowing.
12648 * termhooks.h (struct terminal): Likewise.
12649 * xterm.c (xembed_send_message): Likewise.
12651 * insdel.c (make_gap_smaller): Define only if
12652 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
12654 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
12657 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
12658 so that we aren't warned about unused symbols.
12660 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
12662 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
12664 * xfns.c (x_real_positions): Mark locals as initialized.
12666 * xmenu.c (xmenu_show): Don't use uninitialized vars.
12668 * xterm.c: Fix problems found by static analysis with other toolkits.
12669 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.

12765 * nsfont.m: Fixed bugs in ns_get_family and
12766 ns_descriptor_to_entity that were caused by using free to
12767 deallocate memory blocks that were allocated by xmalloc (via

13107 * charset.h (charset_iso_8859_1): Remove decl.
13108 * charset.c (charset_iso_8859_1, charset_emacs, map_charset_for_dump):
13111 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
13112 * ccl.c (Vccl_program_table): Now static.
13113 (check_ccl_update): Remove; unused.
13115 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
13116 * category.h: ... from here.
13117 * category.c (check_category_table, set_category_set): Now static.
13119 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
13120 * lisp.h: Remove these decls.
13122 * buffer.c (buffer_count): Remove unused var.
13124 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
13125 so that it's not optimized away.
13126 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13127 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13128 exported only to the debugger.
13130 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
13131 * atimer.h (run_all_atimers): Remove; not exported.
13133 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13134 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13135 was inaccessible from Lisp.
13136 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13137 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13139 alloc.c: Import and export fewer symbols, and remove unused items.
13140 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13142 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13143 it's not optimized away by whole-program optimization.
13144 (message_enable_multibyte, free_misc): Remove.
13145 (catchlist, handlerlist, mark_backtrace):
13146 Declare only if BYTE_MARK_STACK.
13147 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
13148 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
13149 (message_enable_multibyte): Remove decl.
13150 (free_misc, interval_free_list, float_block, float_block_index):
13151 (n_float_blocks, float_free_list, cons_block, cons_block_index):
13152 (cons_free_list, last_marked_index):
13154 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
13155 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13156 (mark_backtrace): Define only if BYTE_MARK_STACK.
13157 * xdisp.c (message_enable_multibyte): Now static.
13159 Declare Lisp_Object Q* variables to be 'static' if not exported.
13160 This makes it easier for human readers (and static analyzers)
13161 to see whether these variables are used from other modules.
13162 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13163 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13164 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

13167 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
13168 * xmenu.c, xselect.c:
13169 Declare Q* vars static if they are not used in other modules.
13170 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
13171 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
13172 Remove decls of unexported vars.
13173 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13175 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13177 Make Emacs functions such as Fatom 'static' by default.
13178 This makes it easier for human readers (and static analyzers)
13179 to see whether these functions can be called from other modules.
13180 DEFUN now defines a static function. To make the function external
13181 so that it can be used in other C modules, use the new macro DEFUE.
13182 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13183 (Finit_image_library):
13184 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13185 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13186 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13187 Remove decls, since these functions are now static.
13188 (Funintern, Fget_internal_run_time): New decls, since these functions
13189 were already external.
13191 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13192 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13198 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13199 Mark functions with DEFUE instead of DEFUN,
13200 if they are used in other modules.
13201 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13202 decls for now-static functions.
13203 * buffer.h (Fdelete_overlay): Remove decl.
13204 * callproc.c (Fgetenv_internal): Mark as internal.
13205 * composite.c (Fremove_list_of_text_properties): Remove decl.

13209 * doc.c (Fdocumntation_property): New forward static decl.
13210 * eval.c (Ffetch_bytecode): New forward static decl.
13211 (Funintern): Remove extern decl; now in .h file where it belongs.
13212 * fileio.c (Fmake_symbolic_link): New forward static decl.
13213 * image.c (Finit_image_library): New forward static decl.
13214 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13215 * intervals.h (Fprevious_property_change):
13216 (Fremove_list_of_text_properties): Remove decls.
13217 * keyboard.c (Fthis_command_keys): Remove decl.
13218 (Fcommand_execute): New forward static decl.
13219 * keymap.c (Flookup_key): New forward static decl.
13220 (Fcopy_keymap): Now static.
13221 * keymap.h (Flookup_key): Remove decl.
13222 * process.c (Fget_process): New forward static decl.
13223 (Fprocess_datagram_address): Mark as internal.

13234 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13236 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13239 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13241 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13242 when at ZV. (Bug#8487)
13244 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13246 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13248 * keyboard.c (parse_tool_bar_item): Likewise.
13249 * sound.c (sound_cleanup, alsa_close): Likewise.
13250 * termcap.c (tgetent): Likewise.
13251 * xfns.c (x_default_font_parameter): Likewise.
13252 * xsettings.c (read_and_apply_settings): Likewise.
13254 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13255 (overrun_check_free): Protoize.
13257 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13259 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13260 since callers should never pass a negative size.
13261 Change the signature to match that of plain 'read' and 'write'; see
13262 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13263 * lisp.h: Update prototypes of emacs_write and emacs_read.
13265 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13267 * xdisp.c (redisplay_window): Don't try to determine the character
13268 position of the scroll margin if the window start point w->startp
13269 is outside the buffer's accessible region. (Bug#8468)
13271 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13273 Fix write-region and its subroutines for buffers > 2GB.
13274 * fileio.c (a_write, e_write): Modify declaration of arguments and
13275 local variables to support buffers larger than 2GB.
13276 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13278 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13279 argument, local variables, and return value.
13281 * lisp.h: Update prototypes of emacs_write and emacs_read.
13283 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13285 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13287 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13289 Fix more problems found by GCC 4.6.0's static checks.
13291 * xdisp.c (vmessage): Use a better test for character truncation.
13293 * charset.c (load_charset_map): <, not <=, for optimization,
13294 and to avoid potential problems with integer overflow.
13295 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13296 * casetab.c (set_identity, shuffle): Likewise.
13297 * editfns.c (Fformat): Likewise.
13298 * syntax.c (skip_chars): Likewise.
13300 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13301 This also lets GCC 4.6.0 generate slightly better loop code.
13303 * callint.c (Fcall_interactively): <, not <=, for optimization.
13304 (Fcall_interactively): Count the number of arguments produced,
13305 not the number of arguments given. This is simpler and lets GCC
13306 4.6.0 generate slightly better code.
13308 * ftfont.c: Distingish more carefully between FcChar8 and char.
13309 The previous code passed unsigned char * to a functions like
13310 strlen and xstrcasecmp that expect char *, which does not
13311 conform to the C standard.
13312 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13313 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13314 char * when the C standard requires it.
13316 * keyboard.c (read_char): Remove unused var.
13318 * eval.c: Port to Windows vsnprintf (Bug#8435).
13319 Include <limits.h>.
13320 (SIZE_MAX): Define if the headers do not.
13321 (verror): Do not give up if vsnprintf returns a negative count.
13322 Instead, grow the buffer. This ports to Windows vsnprintf, which
13323 does not conform to C99. Problem reported by Eli Zaretskii.
13324 Also, simplify the allocation scheme, by avoiding the need for
13325 calling realloc, and removing the ALLOCATED variable.
13327 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13329 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13330 But keep the doprint source code for now, as we might revamp it
13331 and use it again (Bug#8435).
13332 * lisp.h (doprnt): Remove.
13333 * Makefile.in (base_obj): Remove doprnt.o.
13334 * deps.mk (doprnt.o): Remove.
13336 error: Print 32- and 64-bit integers portably (Bug#8435).
13337 Without this change, on typical 64-bit hosts error ("...%d...", N)
13338 was used to print both 32- and 64-bit integers N, which relied on
13339 undefined behavior.
13340 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13341 * lisp.h (error, verror): Mark as printf-like functions.
13342 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13343 Report overflow in size calculations when allocating printf buffer.
13344 Do not truncate output string at its first null byte.
13345 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13346 Truncate the output at a character boundary, since vsnprintf does not
13348 * charset.c (check_iso_charset_parameter): Convert internal
13349 character to string before calling 'error', since %c now has the
13351 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13352 overflow when computing char to be passed to 'error'. Do not
13353 pass Lisp_Object to 'error'; pass the integer instead.
13354 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13355 formatted with plain %d.
13357 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13359 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13361 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13363 * xterm.c (x_catch_errors): Remove duplicate declaration.
13365 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13367 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13369 2011-04-10 Jim Meyering <meyering@redhat.com>
13371 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13372 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13373 return ssize_t not "int", and use size_t as the buffer length.
13374 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13375 * gnutls.h: Update declarations.
13376 * process.c (read_process_output): Use ssize_t, to match.
13377 (send_process): Likewise.
13379 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13381 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13383 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13385 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13386 Use unsigned char, to match FcChar8 type definition.
13388 * xterm.c (handle_one_xevent):
13389 * xmenu.c (create_and_show_popup_menu):
13390 * xselect.c (x_decline_selection_request)
13391 (x_reply_selection_request): Avoid type-punned deref of X events.
13393 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13395 Fix some uses of `int' instead of EMACS_INT.
13396 * search.c (string_match_1, fast_string_match)
13397 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13398 (scan_buffer, find_next_newline_no_quit)
13399 (find_before_next_newline, search_command, Freplace_match)
13400 (Fmatch_data): Make some `int' variables be EMACS_INT.
13402 * xdisp.c (display_count_lines): 3rd argument and return value now
13403 EMACS_INT. All callers changed.
13404 (pint2hrstr): Last argument is now EMACS_INT.
13406 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13407 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13408 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13409 (decode_coding_utf_16, decode_coding_emacs_mule)

13411 (decode_coding_ccl, decode_coding_charset)
13412 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13413 (decode_coding_iso_2022, decode_coding_emacs_mule)
13414 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13415 <char_offset, last_offset>: Declare EMACS_INT.

13419 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13420 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13422 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13423 (encode_invocation_designation): Last argument P_NCHARS is now
13425 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13426 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13428 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13431 * ccl.c (Fccl_execute_on_string): Declare some variables
13434 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13436 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13438 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13440 * process.c (Fformat_network_address): Doc fix.
13442 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13444 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13446 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13448 * keyboard.c (read_char): Call Lisp function help-form-show,
13449 instead of using internal_with_output_to_temp_buffer.
13450 (Qhelp_form_show): New var.
13451 (syms_of_keyboard): Use DEFSYM macro.
13453 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13460 (list_processes_1): Delete.
13462 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13464 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13466 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13468 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13470 Fix more problems found by GCC 4.6.0's static checks.
13472 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13474 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13476 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13478 * xdisp.c (vmessage): Mark as a printf-like function.
13480 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13482 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13484 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13485 printf-like functions.

13487 to system-supplied API.
13489 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13491 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13492 This avoids several warnings with gcc -Wstrict-overflow.
13493 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13494 directly, rather than having caller test rule sign. This avoids
13495 some unnecessary tests.
13496 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13497 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13498 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13500 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13501 (xfont_open): Avoid unnecessary tests.
13503 * composite.c (composition_gstring_put_cache): Use unsigned integer.

13512 by using the new macro.
13514 * textprop.c (set_text_properties_1): Change while to do-while,
13515 since the condition is always true at first.
13517 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13518 (interval_deletion_adjustment): Return unsigned value.
13521 * process.c (list_processes_1, create_pty, read_process_output):

13535 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13537 * print.c (print_error_message): Avoid int overflow.
13539 * font.c (font_list_entities): Redo for clarity,
13540 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

13548 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13550 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13551 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13552 can always succeed if overflow has undefined behavior.
13554 * search.c (boyer_moore, wordify): Remove vars set but not used.
13555 (wordify): Omit three unnecessary tests.
13557 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13558 All callers changed. This avoids the need for an unused var.
13560 * casefiddle.c (casify_region): Remove var that is set but not used.
13562 * dired.c (file_name_completion): Remove var that is set but not used.
13564 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13566 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13567 (Finsert_file_contents): Remove unnecessary code checking fd.
13569 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13570 Check for integer overflow on size calculations.
13572 * buffer.c (Fprevious_overlay_change): Remove var that is set
13575 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13576 Remove vars that are set but not used.
13577 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13578 (timer_check_2): Mark vars as initialized.
13580 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13582 * image.c (lookup_image): Remove var that is set but not used.
13583 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13585 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13586 that are set but not used.
13588 * xfns.c (make_invisible_cursor): Don't return garbage
13589 if XCreateBitmapFromData fails (Bug#8410).
13591 * xselect.c (x_get_local_selection, x_handle_property_notify):
13592 Remove vars that are set but not used.
13594 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13595 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13597 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13598 Remove var that is set but not used.
13599 (scroll_bar_windows_size): Now size_t, not int.
13600 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13601 Check for overflow.
13603 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13604 (map_tty_color) [!defined MSDOS]: Likewise.
13606 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13608 * coding.c: Remove vars that are set but not used.
13609 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13610 All callers changed.
13611 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13612 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13613 (decode_coding_charset): Remove vars that are set but not used.
13615 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13616 that is set but not used.
13618 * print.c (print_object): Remove var that is set but not used.
13620 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13621 The gnulib version avoids calling malloc in the usual case,
13622 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13623 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13624 * filelock.c (current_lock_owner): Likewise.
13625 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13626 * sysdep.c: Include allocator.h, careadlinkat.h.
13627 (emacs_no_realloc_allocator): New static constant.
13628 (emacs_readlink): New function.
13629 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13630 ../lib/careadlinkat.h.
13632 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13634 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13635 first non-nil return value).

13644 * xdisp.c (display_count_lines): Remove parameter `start',
13645 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13646 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13647 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13649 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13650 and thereabouts. All callers changed.
13651 (get_per_char_metric): Remove parameter `f', unused since
13652 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13654 2011-04-02 Jim Meyering <meyering@redhat.com>
13656 do not dereference NULL upon failed strdup
13657 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13658 (ns_get_family): Likewise.
13660 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13662 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13664 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13666 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13669 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13671 Add lexical binding.
13673 * window.c (Ftemp_output_buffer_show): New fun.
13674 (Fsave_window_excursion):
13675 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13677 * lread.c (lisp_file_lexically_bound_p): New function.
13678 (Fload): Bind Qlexical_binding.
13679 (readevalloop): Remove `evalfun' arg.
13680 Bind Qinternal_interpreter_environment.
13681 (Feval_buffer): Bind Qlexical_binding.
13682 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13684 (syms_of_lread): Declare `lexical-binding'.
13686 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13688 * keyboard.c (eval_dyn): New fun.
13689 (menu_item_eval_property): Use it.
13691 * image.c (parse_image_spec): Use Ffunctionp.
13693 * fns.c (concat, mapcar1): Accept byte-code-functions.
13695 * eval.c (Fsetq): Handle lexical vars.
13696 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13697 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13698 (FletX, Flet): Obey lexical binding.
13699 (Fcommandp): Handle closures.
13700 (Feval): New `lexical' arg.
13701 (eval_sub): New function extracted from Feval. Use it almost
13702 everywhere where Feval was used. Look up vars in lexical env.
13704 (Ffunctionp): Move from subr.el.
13705 (Ffuncall): Handle closures.
13706 (apply_lambda): Remove `eval_flags'.
13707 (funcall_lambda): Handle closures and new byte-code-functions.
13708 (Fspecial_variable_p): New function.
13709 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13710 but without exporting it to Lisp.
13712 * doc.c (Fdocumentation, store_function_docstring):
13713 * data.c (Finteractive_form): Handle closures.
13715 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13718 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13720 (exec_byte_code): New function extracted from Fbyte_code to handle new
13721 calling convention for byte-code-functions. Add new byte-codes.
13723 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13725 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13727 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13729 * xdisp.c (redisplay_internal): Fix prototype.
13731 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13733 * xdisp.c (SCROLL_LIMIT): New macro.
13734 (try_scrolling): Use it when setting scroll_limit.
13735 Limit scrolling to 100 screen lines.
13736 (redisplay_window): Even when falling back on "recentering",
13737 position point in the window according to scroll-conservatively,
13738 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13740 (try_scrolling): When point is above the window, allow searching
13741 as far as scroll_max, or one screenful, to compute vertical
13742 distance from PT to the scroll margin position. This prevents
13743 try_scrolling from unnecessarily failing when
13744 scroll-conservatively is set to a value slightly larger than the
13745 window height. Clean up the case of PT below the margin at bottom
13746 of window: scroll_max can no longer be INT_MAX. When aggressive
13747 scrolling is in use, don't let point enter the opposite scroll
13748 margin as result of the scroll.
13749 (syms_of_xdisp) <scroll-conservatively>: Document the
13750 threshold of 100 lines for never-recentering scrolling.
13752 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13754 * dispextern.h (move_it_by_lines):

13757 (message_log_check_duplicate): Remove parameters `prev_bol' and
13758 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13759 (redisplay_internal): Remove parameter `preserve_echo_area',
13760 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13762 * indent.c (Fvertical_motion):
13763 * window.c (window_scroll_pixel_based, Frecenter):
13764 Don't pass `need_y_p' to `move_it_by_lines'.
13766 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13768 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13769 steal a few bits to be more compact.
13770 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13771 Remove unneeded casts.
13773 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13775 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13777 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13778 binding" message (bug#7967).
13780 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13782 Fix more problems found by GCC 4.6.0's static checks.
13784 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13785 Remove unused local var.
13787 * editfns.c (Fmessage_box): Remove unused local var.
13789 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13790 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13791 Omit unused local vars.
13792 * window.c (shrink_windows): Omit unused local var.
13793 * menu.c (digest_single_submenu): Omit unused local var.
13794 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13795 Omit unused local var.
13797 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13798 Don't assume string length fits in int.
13799 (keyremap_step, read_key_sequence): Use size_t for sizes.
13800 (read_key_sequence): Don't check last_real_key_start redundantly.
13802 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13803 instead of alloca (Bug#8344).
13805 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13806 (Fbacktrace_frame): Don't assume nframes fits in int.
13808 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13810 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13813 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13815 * cm.c (calccost): Turn while-do into do-while, for clarity.
13817 * keyboard.c (syms_of_keyboard): Use the same style as later
13818 in this function when indexing through an array. This also
13819 works around GCC bug 48267.
13821 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13823 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13825 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13826 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13828 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13829 This avoids undefined behavior on integer overflow, and is a bit
13830 more convenient anyway since it is compared to a size_t variable.
13832 Variadic C functions now count arguments with size_t, not int.
13833 This avoids an unnecessary limitation on 64-bit machines, which
13834 caused (substring ...) to crash on large vectors (Bug#8344).
13835 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13836 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13844 * fns.c (concat): Likewise.
13845 * frame.c (x_set_frame_parameters): Likewise.
13846 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13847 0 if not found, not -1. All callers changed.
13849 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13850 (stack_copy_size): Now size_t, not int.
13851 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13853 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13855 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13856 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13857 All callers changed.
13859 * lisp.h (multibyte_char_to_unibyte):
13860 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13861 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13872 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13873 don't set the hook to nil, but remove the offending function instead.
13874 (Qcommand_hook_internal): Remove, unused.
13875 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13876 Vcommand_hook_internal.
13878 * eval.c (enum run_hooks_condition): Remove.
13879 (funcall_nil, funcall_not): New functions.
13880 (run_hook_with_args): Call each function through a `funcall' argument.
13881 Remove `cond' argument, now redundant.

13894 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13895 All callers changed.
13897 * w32.c (_wsa_errlist): Use braces for struct initializers.
13899 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

14046 * term.c (Fsuspend_tty, Fresume_tty):
14047 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14048 * window.c (temp_output_buffer_show):
14049 * insdel.c (signal_before_change):
14050 * frame.c (Fhandle_switch_frame):

14056 * buffer.c (Fkill_all_local_variables):
14057 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14059 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14060 unconditionally since it does the check itself.
14062 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14064 Fix more problems found by GCC 4.5.2's static checks.
14066 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14067 the first time through the loop, since we know p0 < p1 then.
14068 This also avoids a gcc -Wstrict-overflow warning.
14070 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14071 leading to a memory leak, possible in functions like
14072 load_charset_map_from_file that can allocate an unbounded number
14073 of objects (Bug#8318).
14075 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14076 that could (at least in theory) be that large.
14078 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14079 This is less likely to overflow, and avoids undefined behavior if
14080 overflow does occur. All callers changed. Use strtoul to scan
14081 for the unsigned long integer.
14082 (pint2hrstr): Simplify and tune code slightly.
14083 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14085 * scroll.c (do_scrolling): Work around GCC bug 48228.
14086 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
14088 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
14089 This also avoids a warning with gcc -Wstrict-overflow.

14091 This also avoids a warning with gcc -Wstrict-overflow.
14093 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14096 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14098 * process.c (Fmake_network_process): Use socklen_t, not int,
14099 where POSIX says socklen_t is required in portable programs.
14100 This fixes a porting bug on hosts like 64-bit HP-UX, where
14101 socklen_t is wider than int (Bug#8277).
14102 (Fmake_network_process, server_accept_connection):
14103 (wait_reading_process_output, read_process_output):
14106 * process.c: Rename or move locals to avoid shadowing.

14116 Make tparam.h and terminfo.c consistent.
14117 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14118 Include tparam.h instead, since it declares them.
14119 * cm.h (PC): Remove extern decl; tparam.h now does this.
14120 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14121 * terminfo.c: Include tparam.h, to check interfaces.
14122 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14123 (tparam): Adjust signature to match interface in tparam.h;
14124 this removes some undefined behavior. Check that outstring and len
14125 are zero, which they always are with Emacs.
14126 * tparam.h (PC, BC, UP): New extern decls.
14128 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14129 (xftfont_open): Rename locals to avoid shadowing.
14131 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14132 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

14143 * composite.c (composition_compute_stop_pos): Rename local to
14145 (composition_reseat_it): Remove unused locals.
14146 (find_automatic_composition, composition_adjust_point): Likewise.
14147 (composition_update_it): Mark var as initialized.
14148 (find_automatic_composition): Mark vars as initialized,
14149 with a FIXME (Bug#8290).

14152 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14153 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14154 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14155 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14156 to avoid shadowing.
14158 * textprop.c (property_change_between_p): Remove; unused.
14160 * intervals.c (interval_start_pos): Now static.
14162 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14165 Rename locals to avoid shadowing.
14167 * sound.c (wav_play, au_play, Fplay_sound_internal):
14168 Fix pointer signedness.
14169 (alsa_choose_format): Remove unused local var.
14170 (wav_play): Initialize a variable to 0, to prevent undefined
14171 behavior (Bug#8278).
14173 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14175 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14177 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14178 clobbering (Bug#8298).
14179 * sysdep.c (sys_subshell): Likewise.
14180 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14182 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14183 This should get cleaned up, so that child_setup has the
14184 same signature on all platforms.
14186 * callproc.c (call_process_cleanup): Now static.
14187 (relocate_fd): Rename locals to avoid shadowing.
14189 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14191 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14192 not to be necessary, and produces flickering.
14194 2011-03-20 Glenn Morris <rgm@gnu.org>
14196 * config.in: Remove file.
14198 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14200 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14201 are now in src/globals.h.
14202 (syms_of_minibuf): Remove spurious & from previous change.
14204 2011-03-20 Leo Liu <sdl.web@gmail.com>
14206 * minibuf.c (completing-read-function): New variable.
14207 (completing-read-default): Rename from completing-read.
14208 (completing-read): Call completing-read-function.
14210 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14212 * xfaces.c (Fx_load_color_file):
14213 Read color file from absolute filename (bug#8250).
14215 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14217 * makefile.w32-in: Update dependencies.
14219 2011-03-17 Eli Zaretskii <eliz@gnu.org>
14221 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

14228 (sigchld_handler): Now static.
14230 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14231 That way, the code declares only the vars that it needs.
14232 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
14233 * s/cygwin.h (PTY_ITERATION): Likewise.
14234 * s/darwin.h (PTY_ITERATION): Likewise.

14241 (CONSTANTLIM): Remove; unused.
14242 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14243 Define only if needed.
14245 * unexelf.c (unexec): Name an expression,
14246 to avoid gcc -Wbad-function-cast warning.
14247 Use a different way to cause a compilation error if anyone uses
14248 n rather than nn, a way that does not involve shadowing.
14249 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14251 * deps.mk (unexalpha.o): Remove; unused.
14253 New file unexec.h, the (simple) interface for unexec (Bug#8267).
14254 * unexec.h: New file.
14255 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
14256 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
14257 Depend on unexec.h.
14258 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
14259 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
14260 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
14261 Change as necessary to match prototype in unexec.h.
14263 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

14316 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14317 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14318 some of which prompt warnings from gcc -Wbad-function-cast.
14319 (Fformat_time_string, Fencode_time, Finsert_char):
14320 (Ftranslate_region_internal, Fformat):
14321 Rename or remove local vars to avoid shadowing.
14322 (Ftranslate_region_internal): Mark var as initialized.
14324 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
14327 * lisp.h (eassert): Check that the argument compiles, even if
14328 ENABLE_CHECKING is not defined.
14330 * data.c (Findirect_variable): Name an expression, to avoid
14331 gcc -Wbad-function-cast warning.

14340 Rename locals to avoid shadowing.
14341 (mark_stack): Move local variables into the #ifdef region where
14343 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
14344 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
14346 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
14347 (GC_STRING_CHARS): Remove; not used.
14348 (Fmemory_limit): Cast sbrk's returned value to char *.
14350 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14356 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14357 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14358 to use the following functions instead of these macros.
14359 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14360 EMACS_INT, since callers assume the returned value fits in int.
14361 (upcase1): Likewise, for UPCASE_TABLE.
14362 (uppercasep, lowercasep, upcase): New static inline functions.
14363 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14367 Rename locals to avoid shadowing.
14368 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14369 (regex_compile, re_search_2, re_match_2_internal):
14370 Remove unused local vars.
14371 (FREE_VAR): Rewrite so as not to use empty "else",
14372 which gcc can warn about.
14373 (regex_compile, re_match_2_internal): Mark locals as initialized.
14374 (RETALLOC_IF): Define only if needed.
14375 (WORDCHAR_P): Likewise. This one is never needed, but is used
14376 only in a comment talking about a compiler bug, so put inside
14377 the #if 0 of that comment.
14378 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14379 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14382 * search.c (boyer_moore): Rename locals to avoid shadowing.
14383 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
14384 (PREV_CHAR_BOUNDARY): Likewise.
14386 * search.c (simple_search): Remove unused var.
14388 * dired.c (compile_pattern): Move decl from here ...

14396 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14397 Rename locals to avoid shadowing.
14398 (Fvertical_motion): Mark locals as initialized.
14400 * casefiddle.c (casify_object, casify_region): Now static.
14401 (casify_region): Mark local as initialized.
14403 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14405 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14406 New macros, so that the caller can use some names other than
14407 gcpro1, gcpro2, etc.
14408 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14410 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14411 argument, for consistency with GCPRO2_VAR, etc: it is now the
14412 prefix of the variable, not the variable itself. All uses
14414 * dired.c (directory_files_internal, file_name_completion):
14415 Rename locals to avoid shadowing.
14417 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14418 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14419 dired.c's scmp function, had undefined behavior.
14420 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14421 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14422 * buffer.h: ... to here, because these macros use current_buffer,
14423 and the new implementation with inline functions needs to have
14424 current_buffer in scope now, rather than later when the macros
14426 (downcase, upcase1): New static inline functions.
14427 (DOWNCASE, UPCASE1): Reimplement using these functions.
14428 This avoids undefined behavior in expressions like
