22 2012-08-04 Eli Zaretskii <eliz@gnu.org>
24 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
25 * w32.c (init_environment): Change the default values of many
26 environment variables in dflt_envvars[] to NULL, to avoid pushing
27 them into environment when they were not already defined. Remove
28 the code that deletes site-lisp subdirectories from the default
29 value of EMACSLOADPATH, as it is no longer needed.
30 (check_windows_init_file): Now external, not static. Use
31 Vload_path as is, without adding anything, as this function is now
32 called when Vload_path is already set up.
34 * w32.h (check_windows_init_file): Add prototype.
36 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
37 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
38 compatibility with Posix platforms.
39 (main): Move the call to check_windows_init_file to here from
41 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
42 any, in the DEFALT argument into the root of the Emacs build or
43 installation tree, as appropriate.
45 * callproc.c (init_callproc_1): Call decode_env_path instead of
46 doing its equivalent by hand.
47 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
48 the code that sets Vexec_path run on MS-Windows.
50 * lread.c (init_lread): Add comments to #ifdef's.
52 * msdos.c (dos_set_window_size, IT_update_begin)
53 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
54 instead of direct references.
56 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
58 Export DEFAULT_REHASH_* to GDB.
59 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
60 Now constants, not macros.
62 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
64 Remove unnecessary casts involving pointers.
65 These casts are no longer needed now that we assume C89 or later,
66 since they involve casting to or from void *.
67 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
68 (make_pure_float, make_pure_vector):
69 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):
70 * macros.c (Fstart_kbd_macro):
71 * menu.c (find_and_return_menu_selection):
72 * minibuf.c (read_minibuf_noninteractive):
73 * sysdep.c (closedir):
74 * xdisp.c (x_produce_glyphs):
75 * xfaces.c (compare_fonts_by_sort_order):
76 * xfns.c (x_real_positions, select_visual):
77 * xselect.c (x_stop_queuing_selection_requests)
78 (x_get_window_property, x_get_window_property_as_lisp_data):
79 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
80 Remove unnecessary pointer casts.
81 * alloc.c (record_xmalloc): New function.
82 * lisp.h (record_xmalloc): New decl.
83 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
84 more like a function. This is because the pointer cast is not
85 needed. All uses changed.
86 * print.c (print_string, print_error_message): Avoid length recalc.
88 Improve fix for macroexp crash with debugging (Bug#12118).
89 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
90 ARRAY_MARK_FLAG when checking subscripts, because ASET is
91 not supposed to be invoked from the garbage collector.
92 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
93 (gc_aset): New function, which is like ASET but can be
94 used in the garbage collector.
95 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
96 (set_hash_index): Use it instead of ASET.

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

161 * composite.c (COMPOSITE_INLINE):
162 * dispnew.c (DISPEXTERN_INLINE):
163 * sysdep.c (SYSTIME_INLINE):
164 Define to EXTERN_INLINE, so that the corresponding functions
165 are compiled into code.
166 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
167 (INLINE_HEADER_END): New macros.
168 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
169 since it's used in non-static inline functions now.

188 hard-coding the path separator.
190 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
192 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
193 This how ASET and AREF are supposed to work, and makes
194 it easier to think about future improvements. See
195 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
196 * charset.h (set_charset_attr): New function.
197 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
198 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

608 * alloc.c (listn): Fix the order the arguments are consed onto the
611 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
612 enumeration constants, as PURE and HEAP are too general, and clash
613 with other headers and sources, such as gmalloc.c and the
614 MS-Windows system headers. All users changed.
616 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

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

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

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

700 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
701 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
702 not be usable in #if. This simplifies things.
704 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
706 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
708 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

711 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
712 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
713 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
714 Adjust to changes in lisp.h and emacs.c, by using
715 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
716 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
717 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
718 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
719 instead of gdb_valbits.
720 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
721 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
722 instead of gdb_array_mark_flag.
723 (xboolvector): Get size from $->size, not $->header.size.
724 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
725 (xreload, hook-run, hookpost-run): Remove.
726 * emacs.c: Include <verify.h>.
727 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
728 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
730 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
731 (gdb_USE_LSB_TAG): New enum constants.
732 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

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

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

753 add argument, tune behavior, and adjust all callers.
755 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
757 Use typedef for EMACS_INT, EMACS_UINT.
758 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
759 than macros. This simplifies debugging in the usual case, since
760 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
761 and it allows expressions involving EMACS_INT casts.
762 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
764 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

778 buffer is definitely dead. This should really fix an issue reported
779 by Christoph Scholtes again. (Bug#12007).
780 (init_buffer_once): Initialize indirection counters of
781 buffer_defaults and buffer_local_symbols (for sanity and safety).
783 2012-07-24 Eli Zaretskii <eliz@gnu.org>
785 * xdisp.c (init_iterator): Don't compute dimensions of truncation
786 and continuation glyphs on tooltip frames, leave them at zero.
787 Avoids continued lines in tooltips. (Bug#11832)
789 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

817 * buffer.c (Fbuffer_swap_text): Swap indirections too.
818 This avoids crash reported by Christoph Scholtes at
819 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
821 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
823 * nsmenu.m (Popdown_data): New struct.
824 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
826 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

846 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
848 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
849 as it's limited by the amount of memory, not by INT_MAX.
851 2012-07-21 Eli Zaretskii <eliz@gnu.org>
853 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
854 in special-event-map. See the discussion at

1577 * s/aix4-2.h (unix): Remove; no longer needed.
1579 EMACS_TIME simplification (Bug#11875).
1580 This replaces macros (which typically do not work in GDB)

1582 The functional style also makes code easier to read and maintain.
1583 * systime.h: Include <sys/time.h> on all hosts, not just if
1584 WINDOWSNT, since 'struct timeval' is needed in general.

1622 * nsterm.m: Include <ftoastr.h>.
1624 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1625 Prefer snprintf to strncpy.
1626 * nsterm.m (ns_term_init):
1627 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1628 * nsterm.m (ns_term_init):
1629 Avoid the need for strncpy, by using build_string or
1630 make_unibyte_string directly. Use dtoastr, not snprintf.
1631 * process.c (Fmake_network_process): Diagnose service names that
1632 are too long, rather than silently truncating them or creating
1633 non-null-terminated names.

1650 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1651 where argument type is known to be a Lisp_Cons.

1706 O_RDONLY already includes it).
1708 Stop ns builds setting the EMACSLOADPATH environment variable.
1709 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1710 Now it does not set EMACSLOADPATH, just returns the load-path string.

1712 * lread.c [HAVE_NS]: Include nsterm.h.
1713 (init_lread) [HAVE_NS]: Use ns_load_path.

1783 Move marker debugging code under MARKER_DEBUG.
1784 * marker.c (MARKER_DEBUG): Move marker debugging code under
1785 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1786 for bootstrap with --enable-checking (~3x slowdown reported

1840 * lread.c (load_path_check): New function, split from init_lread.
1841 (init_lread): Reorganize. Motivation:
1842 If EMACSLOADPATH is set, check/warn about that rather than the
1843 defaults, which we are not going to use. Hence we can remove
1844 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1845 Don't warn if site-lisp directories are missing.
1846 If not installed, start from a blank load-path, since
1847 PATH_LOADSEARCH refers to the eventual installation directories.
1849 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1851 Support truncation and continuation glyphs on GUI frames, when
1852 fringes are disabled. (Bug#11832)
1853 * xdisp.c (init_iterator): Get dimensions of truncation and
1854 continuation glyphs even if on GUI frames. Adjust
1855 it->last_visible_x on GUI frames when the left or right fringes,
1856 or both, are absent.
1857 (start_display, move_it_in_display_line_to): Handle the case of a
1858 GUI frame without a fringe to display continuation or truncation
1860 (insert_left_trunc_glyphs): Support GUI frames: make sure
1861 truncation glyphs overwrite enough glyphs from the current line to
1862 have sufficient space in pixels.
1863 (display_line): Support truncation and continuation glyphs on GUI
1864 frames. If some spare pixels are left on the line after inserting
1865 the truncation glyphs, fill that space with a stretch glyph of a
1866 suitably computed width.
1868 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1869 produce_glyphs, to support GUI sessions.
1871 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1873 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1875 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1877 Do not require float-time's arg to fit in time_t (Bug#11825).
1878 This works better on hosts where time_t is unsigned, and where
1879 float-time is applied to the (negative) difference between two times.
1880 * editfns.c (decode_time_components): Last arg is now double *,
1881 not int *, and means to store all the result as a double, without
1882 worrying about whether the seconds part fits in time_t.
1883 All callers changed.
1884 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1885 All callers changed.
1886 (Ffloat_time): Do not fail merely because the specified time falls
1887 outside of time_t range.
1889 2012-07-07 Glenn Morris <rgm@gnu.org>
1891 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1902 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1904 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1905 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1906 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1907 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1908 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1909 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1911 * xfont.c (compare_font_names): Redo to omit the need for casts.
1913 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1915 * xfns.c (Fx_change_window_property): Doc fix.
1916 * w32fns.c (Fx_change_window_property): Doc fix.
1918 * w32fns.c (Fx_window_property): Accept the same arguments as the
1919 X Windows version. Doc fix.
1920 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1922 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1923 Eli Zaretskii <eliz@gnu.org>
1925 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1926 Windows-specific code from nt/config.nt moved here.
1927 Obsolete settings removed.
1929 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1931 * process.c: Avoid unnecessary calls to gettime.
1932 (wait_reading_process_output): Don't get the time of day
1933 when gobbling data immediately and not waiting, as there's no need
1934 for it in that case. This removes a FIXME.
1936 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1938 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1939 is defined (Bug#11768).
1941 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1943 Fix marker debugging code.
1944 * marker.c (byte_char_debug_check): Do not perform the check
1945 if buffer is not multibyte.
1946 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1947 Call byte_char_debug_check with correct arguments.
1949 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1951 Compile marker debugging code only if ENABLE_CHECKING is defined.
1952 * marker.c (byte_char_debug_check, count_markers):
1953 Use only if ENABLE_CHECKING is defined.
1954 (byte_debug_flag): Remove.
1955 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1956 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1958 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1960 Avoid code repetition in marker-related functions.
1961 * marker.c (attach_marker): New function.
1962 (Fset_marker, set_marker_restricted, set_marker_both)
1963 (set_marker_restricted_both): Use it.
1964 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1965 Consistently rename charno to charpos.
1966 (marker_position): Add eassert.
1967 (marker_byte_position): Convert to eassert.
1969 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

1975 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1977 Introduce fast path for the widely used marker operation.
1978 * alloc.c (build_marker): New function.
1979 * lisp.h (build_marker): New prototype.
1980 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1981 * composite.c (autocmp_chars): Likewise.
1982 * editfns.c (buildmark): Remove.
1983 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1984 (save_restriction_save): Use build_marker.
1985 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1986 * window.c (save_window_save): Likewise.
1988 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1990 Do not use Fdelete_overlay in delete_all_overlays
1991 to avoid redundant calls to unchain_overlay.
1992 * buffer.c (drop_overlay): New function.
1993 (delete_all_overlays, Fdelete_overlay): Use it.
1994 * minibuf.c (get_minibuffer): Fix comment.
1996 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1998 Port to OpenBSD 5.1 amd64.
1999 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2000 This is needed for OpenBSD, and should be harmless on all BSD systems.
2001 Also, include <sys/sysctl.h>, as it should be available on all
2002 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2003 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2004 use p_pid member, not kp_proc.pid.
2006 2012-07-06 Glenn Morris <rgm@gnu.org>
2008 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2010 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2012 More xmalloc and related cleanup.
2013 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2014 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
2015 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

2019 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2020 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2021 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2023 Omit needless casts involving void * pointers and allocation.
2024 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2025 as the former is more robust if P's type is changed.
2026 Prefer xzalloc to xmalloc + memset 0.
2027 Simplify malloc-or-realloc to realloc.
2028 Don't worry about xmalloc returning a null pointer.
2029 Prefer xstrdup to xmalloc + strcpy.
2030 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2032 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2033 alloca of a constant.
2035 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2037 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2038 hscroll is larger than the line width. Fixes long and futile
2039 looping inside extend_face_to_end_of_line (on a TTY) producing
2040 glyphs that are not needed and thrown away.
2042 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2044 * marker.c (set_marker_restricted_both): Simplify by using
2047 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2049 * editfns.c (region_limit): Simplify by using clip_to_bounds.
2051 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

2054 not defined (Bug#11768).
2055 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2056 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2057 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2058 followed by gtk_box_set_homogeneous (Bug#11768).
2059 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2060 (update_theme_scrollbar_width, xg_create_scroll_bar):
2061 Use gtk_scrollbar_new (Bug#11768).
2062 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2063 (is_box_type): New function (Bug#11768).
2064 (xg_tool_item_stale_p): Call is_box_type.
2065 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2066 with default display (Bug#11768).
2068 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2070 * xdisp.c (window_hscroll_limited): New function.
2071 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2072 coordinates when window's hscroll is set to insanely large
2075 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2077 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2078 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2080 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2083 * lisp.h (xzalloc): New prototype. Omit needless casts.
2084 * alloc.c (xzalloc): New function. Omit needless casts.

2136 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2138 * fileio.c (time_error_value): Check the right error number.
2139 Problem reported by Troels Nielsen in
2140 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2142 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2144 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2145 This should be fixed in a better way; see Eli Zaretskii in
2146 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2147 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2149 * fileio.c (time_error_value): Rename from special_mtime.
2150 The old name's problems were noted by Eli Zaretskii in
2151 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2153 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2154 This variable's comment says Emacs needs at least one GDB-visible
2155 symbol of type enum pvec_type, to work around GDB problems.
2156 The symbol's value doesn't matter.
2158 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2159 that causes compilation to fail on pre-C99 compilers.
2161 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2163 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2164 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2166 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2168 * buffer.c (init_buffer_once): Fix initialization of
2169 headers for buffer_defaults and buffer_local_symbols.
2170 Reported by Juanma Barranquero <lekktu@gmail.com>.
2172 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2174 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2175 * lisp.h (enum pvec_type): Use fewer bits.
2176 (PSEUDOVECTOR_SIZE_BITS): New constant.
2177 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2178 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2179 change in pvec_type.
2180 (PSEUDOVECTOR_TYPEP): New macro.
2181 (TYPED_PSEUDOVECTORP): Use it.
2182 * fns.c (internal_equal): Adapt code to extract pvectype.
2183 * emacs.c (gdb_pvec_type): Update type.
2184 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2185 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2186 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2187 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2188 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2189 abusing vector->header.next.nbytes.
2190 (live_vector_p): Use PVEC_TYPE.
2191 (mark_object): Adapt code to extract pvectype. Use switch.
2193 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2195 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2196 Tighten new eassert a bit.
2198 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2200 Fix compilation with --enable-gcc-warnings and -O1
2202 * doprnt.c (doprnt): Change type of tem to int, initialize
2203 to avoid compiler warning. Add eassert.
2204 * search.c (simple_search): Initialize match_byte to avoid
2205 compiler warning. Add eassert.
2207 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2209 Avoid weird behavior with large horizontal scrolls.
2210 Without this change, for example, large hscroll values would
2211 mess up Emacs's display on Fedora 15 x86, presumably due to
2212 overflows in int calculations in the display code.
2213 Also, if buffers had long lines, Emacs would freeze.
2214 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2215 (set_window_hscroll): New function, containing the old guts of
2216 Fset_window_hscroll. Return the clipped value.
2217 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2218 This avoids the need to check against PTRDIFF_MAX.
2220 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2222 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2224 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2226 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2228 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2229 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2230 since GCC 4.4.6 issues a bogus warning for them.
2232 Fix bugs in file timestamp newness comparisons.
2233 * fileio.c (Ffile_newer_than_file_p):
2234 * lread.c (Fload): Use full timestamp resolution of files,
2235 not just the 1-second resolution, so that files that are only
2236 slightly newer still count as newer.
2237 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2238 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2240 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2242 * fileio.c: Improve handling of file time marker. (Bug#11852)
2243 (special_mtime): New function.
2244 (Finsert_file_contents, Fverify_visited_file_modtime):
2245 Use it to set special mtime values consistently.
2247 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2249 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2250 marker for non-existing file. (Bug#11852)
2252 2012-07-03 Glenn Morris <rgm@gnu.org>
2254 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2255 and did not make it into globals.h).
2257 2012-07-03 Tom Tromey <tromey@redhat.com>
2259 * window.c (Fset_window_margins, Fset_window_fringes)

2293 * xterm.h: Remove EXFUN.
2295 2012-07-03 Glenn Morris <rgm@gnu.org>
2297 * lisp.h (Frandom): Make it visible to C.
2298 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2299 buffer for invisible buffers. (Bug#1229)
2301 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2303 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2304 values which aren't power of 2.
2305 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2306 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2309 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2311 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2313 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2315 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2317 * alloc.c (allocate_vector_block): Remove redundant
2318 calls to mallopt if DOUG_LEA_MALLOC is defined.
2319 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2320 avoid calls to mallopt if zero_vector is returned.
2322 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2324 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2325 is enabled, avoid dereferencing NULL current_sblock if
2328 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2330 Cleanup basic buffer management.
2331 * buffer.h (struct buffer): Change layout to use generic vector
2332 marking code. Fix some comments. Change type of 'clip_changed'
2333 to bitfield. Remove unused #ifndef old.
2334 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2335 (GET_OVERLAYS_AT): Fix indentation.
2336 (for_each_per_buffer_object_at): New macro.
2337 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2340 * alloc.c (allocate_buffer): Adjust to match new layout of
2341 struct buffer. Fix comment.
2342 (mark_overlay): New function.
2343 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2344 Lisp area of struct buffer.
2345 (mark_object): Use it. Adjust marking of misc objects
2346 and related comments.
2348 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2350 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2351 wrapper that is not needed because the wrapped code is a no-op (zero
2352 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2353 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2355 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2357 * alloc.c (mark_buffer): Simplify. Remove prototype.
2358 (mark_object): Add comment. Reorganize marking of vector-like
2359 objects. Use CHECK_LIVE for all vector-like objects except buffers
2360 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2361 redundant calls to mark_vectorlike for bool vectors.
2363 2012-06-30 Glenn Morris <rgm@gnu.org>
2365 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2367 * epaths.in (PATH_SITELOADSEARCH): New.
2368 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2369 This is rather than relying on --enable-locallisppath elements
2370 having "site-lisp" in their names. (Bug#10208#25, 11658)
2372 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2374 * w32proc.c (sys_select): Accept and ignore one more argument.
2376 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2378 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2379 (pselect) [!MS_DOS]: Redirect to sys_select.
2381 * sysdep.c: Don't include dos.h and dosfns.h.
2383 * process.c (sys_select):
2384 * msdos.c (sys_select): Accept one more argument and ignore it.
2386 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2387 adapt data types and code to that.
2390 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2391 which clashes with the gnulib function of the same name.
2393 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2395 * font.c (font_style_to_value, font_style_symbolic)
2396 (font_prop_validate_style): Add type checks for values in
2399 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2401 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2404 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2406 * xdisp.c (try_window_id): Undo last change.
2408 * w32.c (getwd): Adjust commentary about startup_dir.
2409 (init_environment): Always call sys_access, even in non-MSVC
2410 builds. Don't chdir to the directory of the Emacs executable.
2411 This undoes code from 1997 which was justified by the need to
2412 "avoid conflicts when removing and renaming directories". But its
2413 downside was that every relative file name was being interpreted
2414 relative to the directory of the Emacs executable, which can never
2415 be TRT. In particular, it broke sys_access when called with
2416 relative file names.
2417 (sys_access): Map GetLastError to errno.
2419 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2421 * window.h (struct window): Change type of 'fringes_outside_margins'

2425 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2428 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

2431 Add QUIT to make the loop interruptible.
2433 2012-06-29 Glenn Morris <rgm@gnu.org>
2435 * charset.c (init_charset): Make lack of etc/charsets fatal.
2437 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2439 * editfns.c (region_limit): Fix type mismatch.
2441 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2443 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2444 undefined. Convert from xassert to eassert.
2445 * nsmenu.m: Convert from xassert to eassert.
2446 * nsterm.m: Likewise.
2448 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2450 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2452 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2454 Avoid integer overflow on scroll-left and scroll-right.
2455 * window.c (HSCROLL_MAX): New macro.
2456 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2457 overflow when requested scroll falls outside ptrdiff_t range.

2461 * window.h (struct window): Change type of 'hscroll',
2462 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2463 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2464 Adjust users accordingly.
2465 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2466 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2467 from EMACS_INT to ptrdiff_t.
2468 (make_window): Omit redundant initialization.
2470 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2474 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2476 * window.h (struct window): Change type of 'use_time' and

2543 * alloc.c (allocate_string): Omit intervals initialization.
2544 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2545 as in make_pure_string and make_pure_c_string.

2603 a better opportunity to optimize away calls to strlen when the
2604 function is called with compile-time constant argument.
2605 * image.c (imagemagick_error): Convert to build_string.
2606 * w32proc.c (sys_spawnve): Likewise.

2609 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2611 Use sprintf return value instead of invoking strlen on result.
2612 In the old days this wasn't portable, since some sprintf
2613 implementations returned char *. But they died out years ago and
2614 Emacs already assumes sprintf returns int.
2615 Similarly for float_to_string.
2616 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2623 * xfns.c (syms_of_xfns):
2624 Use sprintf or float_to_string result to avoid need to call strlen.
2625 * data.c (Fnumber_to_string):
2626 Use make_unibyte_string, since the string must be ASCII.
2627 * lisp.h, print.c (float_to_string): Now returns int length.
2628 * term.c (produce_glyphless_glyph):
2629 Use sprintf result rather than recomputing it.
2631 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2632 * Makefile.in (ALL_CFLAGS):

2664 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2667 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2669 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2670 instead of truncating it to 63 (admittedly a generous limit).
2672 * process.c: Fix spelling and caps in comments.
2674 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2676 * emacs.c (setpgrp): Remove definition, unused.

2730 * keyboard.c (kbd_buffer_get_event):
2731 * process.c (Faccept_process_output):

2802 Support higher-resolution time stamps (Bug#9000).
2803 The time stamps are only nanosecond-resolution at the C level,
2804 since that's the best that any real-world system supports now.
2805 But they are picosecond-resolution at the Lisp level, as that's
2806 easy, and leaves room for future OS improvements.
2808 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2811 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2812 Don't get current time unless it's needed.
2814 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2815 now provides it if it's absent.
2816 (start_atimer): Port to higher-res time stamps.
2817 Check for time stamp overflow. Don't get current time more
2818 often than is needed.
2820 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2821 Include systime.h, not time.h.
2822 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2824 * dired.c: Include stat-time.h.
2825 (Ffile-attributes): File times now have higher resolution.
2827 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2828 (struct image): Timestamp now has higher resolution.
2830 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2831 has at least microseconds now. All uses removed.
2832 (update_frame, update_single_window, update_window, update_frame_1)
2833 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2835 * editfns.c (time_overflow): Now extern.
2836 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2837 (float-time, Fformat_time_string, Fcurrent_time_string)
2838 (Fcurrent_time_zone): Accept and generate higher-resolution
2840 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2841 (decode_time_components, lisp_seconds_argument): New functions.
2842 (make_time): Now static.
2843 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2844 Report an error if the time is invalid, rather than having the caller
2847 * fileio.c: Include <stat-time.h>
2848 (Fcopy_file): Copy higher-resolution time stamps.
2849 Prefer to set the time stamp via a file descriptor if that works.
2850 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2851 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2852 (Fvisited_file_modtime, Fset_visited_file_modtime):
2853 Support higher-resolution time stamps.
2855 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2857 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2859 * image.c (prepare_image_for_display, clear_image_cache)
2860 (lookup_image): Port to higer-resolution time stamps.
2862 * keyboard.c (start_polling, bind_polling_period):
2863 Check for time stamp overflow.
2864 (read_char, kbd_buffer_get_event, timer_start_idle)
2865 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2866 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2867 Port to higher-resolution time stamps. Do not assume time_t is signed.
2868 (decode_timer): New function. Timers are now vectors of length 9,
2869 not 8, to accommodate the picosecond component.
2870 (timer_check_2): Use it.
2872 * nsterm.m (select_timeout, timeval_subtract): Remove.
2873 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2874 as they're a bit more accurate and handle overflow better.
2875 (ns_select): Change prototype to be compatible with pselect.
2876 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2877 * nsterm.h (ns_select): Adjust prototype.
2879 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2880 us-resolution time stamps.
2881 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2883 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2885 * lisp.h (time_overflow): New decl.
2886 (wait_reading_process_output): First arg is now intmax_t, not int,
2887 to accommodate larger waits.
2889 * process.h (struct Lisp_Process.read_output_delay):
2890 Now counts nanoseconds, not microseconds.
2891 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2893 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2894 (wait_reading_process_output):
2895 Port to ns-resolution time stamps.
2896 (Faccept_process_output, wait_reading_process_output):
2897 Check for time stamp overflow. Do not assume time_t is signed.
2898 (select_wrapper): Remove; we now use pselect.
2899 (Fprocess_attributes): Now generates ns-resolution time stamps.
2901 * sysdep.c: Include utimens.h. Don't include utime.h
2902 or worry about struct utimbuf; gnulib does that for us now.
2903 (gettimeofday): Remove; gnulib provides a substitute.
2904 (make_timeval): New function.
2905 (set_file_times): Now sets ns-resolution time stamps.
2906 New arg FD; all uses changed.
2907 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2908 (system_process_attributes):
2909 Now returns ns-resolution time stamp. All uses changed.
2910 Check for time stamp overflow.
2912 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2913 provides a substitute now.
2915 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2916 since it guarantees struct timespec.
2917 (EMACS_TIME): Now struct timespec, so that we can support
2918 ns-resolution time stamps.
2919 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2920 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2921 (EMACS_USECS): Remove.
2922 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2923 so multiply the arg by 1000 before storing it.
2924 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2926 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2927 Port to ns-resolution time stamps.
2928 (EMACS_TIME_NEG_P): Remove; replaced by....
2929 (EMACS_TIME_SIGN): New macro.
2930 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2931 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2932 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2933 (make_timeval, make_lisp_time, decode_time_components): New decls.
2934 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2935 that it mishandled time_t overflow. You can't compare by subtracting!
2936 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2937 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2939 * term.c: Include <sys/time.h>.
2940 (timeval_to_Time): New function, for proper overflow wraparound.
2941 (term_mouse_position, term_mouse_click): Use it.
2943 * undo.c (record_first_change): Support higher-resolution time stamps
2945 (Fprimitive_undo): Use them when restoring time stamps.
2947 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2948 (w32_get_internal_run_time):
2949 Port to higher-resolution Emacs time stamps.
2950 (ltime): Now accepts single 64-bit integer, as that's more convenient
2953 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2955 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2956 for compatibility with pselect. Support ns-resolution time stamps.
2958 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2960 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2961 Check for time stamp overflow, and support ns-resolution time stamps.
2963 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2964 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2965 (timeval_subtract): Remove; no longer needed.
2966 (XTflash, XTring_bell, x_wait_for_event):
2967 Port to ns-resolution time stamps. Don't assume time_t is signed.
2969 2012-06-22 Chong Yidong <cyd@gnu.org>
2971 * xdisp.c (x_consider_frame_title): Revert last change.
2973 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2975 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2976 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2977 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2978 staticidx goes up to 1597 out of 1600 = 0x640.)
2980 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2982 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2983 Otherwise, the umask might be mistakenly 0 while handling input signals.
2985 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
2987 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

2993 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2994 access to `contents' member of Lisp_Vector objects with AREF and ASET
2997 2012-06-19 Chong Yidong <cyd@gnu.org>
2999 * frame.c (delete_frame): When selecting a frame on a different
3000 text terminal, do not alter the terminal's top-frame.

3004 (unwind_format_mode_line): Restore them.
3005 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3007 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3008 since tty frames can be explicitly named.
3009 (prepare_menu_bars): Likewise.
3011 * term.c (Ftty_top_frame): New function.
3013 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3015 Port byte-code-meter to modern targets.
3016 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3017 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3018 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3019 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3020 (METER_1, METER_2): Simplify.
3022 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3024 * data.c (Fdefalias): Return `symbol' (bug#11686).
3026 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3028 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3029 gets killed during executing of this function (Bug#11665).
3030 Try to always return Qt when the buffer has been actually killed.
3031 (Vkill_buffer_query_functions): In doc-string say that functions
3032 run by this hook should not change the current buffer.
3034 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3036 Fix recently-introduced process.c problems found by static checking.
3037 * process.c (write_queue_push, write_queue_pop, send_process):
3038 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.

3040 (send_process): Remove unused local.
3042 2012-06-17 Chong Yidong <cyd@gnu.org>

3054 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3056 * lisp.h (eassert): Assume C89 or later.
3057 This removes the need for CHECK.
3058 (CHECK): Remove. Its comments about always evaluating its
3059 argument were confusing, as 'eassert' typically does not evaluate
3062 * coding.c (produce_chars): Use ptrdiff_t, not int.
3064 * xterm.c (x_draw_underwave): Check for integer overflow.
3065 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
3067 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
3069 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

3158 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
3159 If all the glyphs of the glyph row came from strings, and we have no
3160 cursor positioning clues, put the cursor on the first glyph of the

3249 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3250 code works fine either way, and efficiency is not a concern here,
3251 as the union type is for debugging, not for production.
3252 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3253 Use an inline function on all platforms when using the union type,
3254 since this is simpler and 'static inline' can be used portably
3256 (LISP_INITIALLY_ZERO): New macro.
3257 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3258 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3398 * doprnt.c (doprnt): Truncate multibyte char correctly.
3399 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3400 would mishandle a string argument "Xc" if X was a multibyte
3401 character of length 2: it would truncate after X's first byte
3402 rather than including all of X.
3404 2012-06-06 Chong Yidong <cyd@gnu.org>
3406 * buffer.c (word_wrap): Doc fix.

3459 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3461 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3464 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3466 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3468 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3470 For a 'struct window', replace some Lisp_Object fields to
3471 bitfields where appropriate, remove unused fields.
3472 * window.h (struct window): Remove unused 'last_mark_x' and
3473 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3474 change it's type from Lisp_Object to bitfield.
3475 Change type of 'force_start', 'optional_new_start',
3476 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

3483 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3484 Use 'float' consistently, rather than 'float' in most places
3485 and 'double' in a couple of places.
3487 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3489 * xdisp.c (handle_stop): Detect whether we have overlay strings
3490 loaded by testing it->current.overlay_string_index to be
3491 non-negative, instead of checking whether n_overlay_strings is
3492 positive. (Bug#11587)
3494 2012-05-31 Chong Yidong <cyd@gnu.org>
3496 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3498 * doc.c (Fsubstitute_command_keys): Doc fix.
3500 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3502 * search.c (search_buffer): Remove calls to
3503 r_alloc_inhibit_buffer_relocation, as it is now called by
3504 maybe_unify_char, which was the cause of relocation of buffer text
3507 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3509 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3510 for the duration of call to load_charset, to avoid problems with
3511 callers of maybe_unify_char that access buffer text through C
3514 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3515 decrement the inhibition flag, instead of just setting or
3518 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3520 Remove obsolete '#define static' cruft.
3521 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3522 This #undef was "temporary" in 2000; it is no longer needed
3523 now that '#define static' has gone away.
3524 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3525 (gray_bitmap_bits): Remove; no longer needed.
3526 All uses replaced with definiens.
3527 * xterm.c: Include "bitmaps/gray.xbm".
3529 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3531 Clean up __executable_start, monstartup when --enable-profiling.
3532 The following changes affect the code only when profiling.
3533 * dispnew.c (__executable_start): Rename from safe_bcopy.
3534 Define only on platforms that need it.
3535 * emacs.c: Include <sys/gmon.h> when profiling.
3536 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

3538 (safe_bcopy): Remove decl; no longer has that name.
3539 (main): Coalesce #if into single bit of code, for simplicity.

3569 Do not create empty overlays with the evaporate property (Bug#9642).
3570 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3571 Bug#9642, but explicitly check that the buffer the overlay would
3572 be moved to is live and rearrange lines to make sure that errors
3573 will not put the overlay in an inconsistent state.
3574 (Fdelete_overlay): Cosmetics.
3576 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3578 * w32term.c (my_bring_window_to_top): New function.

3590 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3592 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3593 This avoids undefined behavior that might cause the eassert
3594 to not catch an out-of-range value.
3596 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3598 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3612 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3613 Only r_alloc_inhibit_buffer_relocation needed to be added;
3614 the others were already declared.
3616 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3617 before checking whether it's out of range. Put the check inside
3619 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3621 2012-05-27 Ken Brown <kbrown@cornell.edu>
3623 * callproc.c (Fcall_process): Restore a line that was accidentally
3624 commented out in the 2011-02-13 change (bug#11547).

3629 defined on ralloc.c.
3631 * buffer.c [REL_ALLOC]: Remove prototypes of

3633 they are now on lisp.h.
3635 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3637 * search.c (search_buffer): Use it to inhibit relocation of buffer
3638 text while re_search_2 is doing its job, because re_search_2 is
3639 passed C pointers to buffer text. (Bug#11519)
3641 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3644 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

3649 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3652 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3654 Fix coding-related core dumps with gcc -ftrapv.
3655 The code was computing A - B, where A and B are pointers, and B is
3656 random garbage. This can lead to core dumps on platforms that
3657 have special pointer registers, and it also leads to core dumps on
3658 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3659 A - B only when B is initialized properly.
3660 * coding.c (coding_set_source, coding_set_destination): Return void.
3661 (coding_change_source, coding_change_destinations): New functions,
3662 with the old behaviors of coding_set_source and coding_set_destination.

3667 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3669 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3671 Extend mouse support on W32 text-mode console.
3672 * xdisp.c (draw_row_with_mouse_face):
3673 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3675 * w32console.c: Include window.h.
3676 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3678 (initialize_w32_display): Initialize mouse-highlight data.
3680 * w32inevt.c: Include termchar.h and window.h.
3681 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3682 moves, call note_mouse_highlight. If help_echo changed, call
3683 gen_help_event to produce help-echo message in the echo area.
3684 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3687 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3689 * lread.c (read1): Simplify slightly to avoid an overflow warning
3690 with GCC 4.7.0 on x86-64.
3692 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3694 * bidi.c (bidi_mirror_char): Revert last change: an int is
3695 definitely wide enough here.

3707 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3709 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3710 (allocate_pseudovector):
3711 Use int, not EMACS_INT, where int is wide enough.
3712 (inhibit_garbage_collection, Fgarbage_collect):
3713 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3714 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3715 int might not be wide enough.

3724 (advance_to_char_boundary, Fbuffer_swap_text)
3725 (Fset_buffer_multibyte, overlays_at, overlays_in)
3726 (overlay_touches_p, struct sortvec, record_overlay_string)
3727 (overlay_strings, recenter_overlay_lists)
3728 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3729 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3730 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3731 (Foverlay_recenter, last_overlay_modification_hooks_used)
3732 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3733 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3734 (validate_region): Omit unnecessary test for b <= e,
3735 since that's guaranteed by the previous test.
3736 (adjust_overlays_for_delete): Avoid pos + length overflow.
3737 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3738 (report_overlay_modification):
3739 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3740 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3744 * buffer.h: Adjust decls to match defn changes elsewhere.

3749 not int, to avoid needless 32-bit limit on 64-bit hosts.
3750 (exec_byte_code): Use tighter memory-full test, one that checks
3751 for alloca overflow. Don't compute the address of the object just
3752 before an array, as that's not portable. Use EMACS_INT, not
3753 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3754 * callint.c (Fcall_interactively):
3755 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3766 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3767 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3768 (casify_object): Avoid integer overflow when overallocating buffer.
3769 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3772 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3773 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3774 integers are now checked earlier. All uses replaced with XINT.
3776 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3777 For CCL_MapSingle, check that content and value are in int range.

3779 Check that Vcode_version_map_vector is a vector.
3780 (resolve_symbol_ccl_program): Check that vector header is in range.
3781 Always copy the vector, so that we can check its contents reliably
3782 now rather than having to recheck each instruction as it's being
3783 executed. Check that vector words fit in 'int'.
3784 (ccl_get_compiled_code, Fregister_ccl_program)
3785 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3786 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3788 contents are in range.
3789 (Fccl_execute_on_string): Check that status is in range.
3790 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3791 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3792 Accept and return EMACS_INT, not int, because callers can pass values

3799 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3801 avoid mishandling large integers.

3813 Don't assume unsigned int fits into fixnum, or that fixnum fits
3814 into unsigned int. Don't require max_code to be a valid fixnum;
3815 that's not true for gb10830 4-byte on a 32-bit host. Allow
3816 invalid_code to be a cons, for the same reason. Require code_offset
3817 to be a character. Avoid int overflow if max_char is close
3819 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3820 this is intended anyway and avoids some undefined behavior.
3821 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3822 INDEX_TO_CODE_POINT, as that's what it expects.
3823 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3824 * charset.h (DECODE_CHAR): Return int, not unsigned;
3825 this is what was intended anyway, and it avoids undefined behavior.
3826 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3827 integer-overflow issues.
3828 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3829 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3830 where the argument is EMACS_INT, and this behavior is not intended.
3831 * chartab.c (Fmake_char_table, Fset_char_table_range)
3832 (uniprop_get_decoder, uniprop_get_encoder):
3833 Don't assume fixnum fits in int.
3834 * cmds.c (move_point): New function, that does the gist of
3835 Fforward_char and Fbackward_char, but does so while checking
3836 for integer overflow more accurately.
3837 (Fforward_char, Fbackward_char): Use it.
3838 (Fforward_line, Fend_of_line, internal_self_insert)
3839 (internal_self_insert):
3840 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4442 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
4443 (handle_tool_bar_click):
4444 Use int, not unsigned, since we prefer signed and the signedness
4445 doesn't matter here.
4446 (get_next_display_element, next_element_from_display_vector):
4447 Use int, not EMACS_INT, when int is wide enough.
4448 (start_hourglass): Use duration_to_sec_usec to do proper
4449 overflow checking on durations.
4450 * xfaces.c (Fbitmap_spec_p):
4451 Check that fixnums are in proper range for system types.
4452 (compare_fonts_by_sort_order):

4464 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
4465 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
4467 Check that fixnums are in proper range for system types.
4468 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)

4472 * xfont.c (xfont_chars_supported):
4473 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

4481 (x_get_local_selection, x_reply_selection_request)
4482 (x_handle_selection_request, wait_for_property_change):
4483 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4484 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
4485 short is wide enough.
4486 (x_send_client_event): Don't assume fixnum fits in int.
4487 * xterm.c (x_x_to_emacs_modifiers):
4488 Don't assume EMACS_INT overflows nicely into int.
4489 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
4491 (handle_one_xevent): NATNUMP can eval its arg twice.
4492 (x_connection_closed):
4493 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4494 * xterm.h: Adjust decls to match defn changes elsewhere.
4495 (struct scroll_bar): Use struct vectorlike_header
4496 rather than rolling our own approximation.
4497 (SCROLL_BAR_VEC_SIZE): Remove; not used.
4499 2012-05-25 Glenn Morris <rgm@gnu.org>
4501 * lisp.mk (lisp): Update for more files being compiled now.
4503 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
4505 * lread.c: Remove `read_pure' which makes no difference.
4506 (read_pure): Remove var.
4507 (unreadpure): Remove function.
4508 (readevalloop): Don't call read_list with -1 flag.
4509 (read1, read_vector): Don't test read_pure any more.
4510 (read_list): Simplify.
4512 * fileio.c, character.h: Minor style tweaks.
4514 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
4516 * window.h (clip_changed): Remove useless declaration.

4521 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
4523 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4526 This directory predates autoconf and is no longer needed nowadays.
4527 Move its few remaining bits of functionality to where they're needed.
4528 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
4529 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

4536 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
4537 (EMACS_UINT): Define unconditionally now.
4538 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4539 (BITS_PER_EMACS_INT): New constants, replacing
4540 what used to be in config.h, but not useful in #if.
4541 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4542 define them any more.
4543 (VAL_MAX): New macro.
4545 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4546 BITS_PER_EMACS_INT, in #if.
4547 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4548 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4549 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4550 * s/ms-w32.h (DATA_START):
4551 Move here from removed file m/intel386.h.
4552 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4553 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4555 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4557 Assume C89 or later.
4558 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

4565 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4566 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4567 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4568 * xterm.c (input_signal_count): Assume volatile works.
4570 2012-05-21 Ken Brown <kbrown@cornell.edu>
4572 * xgselect.c (xg_select): Fix first argument in call to 'select'
4575 2012-05-20 Ken Brown <kbrown@cornell.edu>
4577 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4578 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4580 2012-05-19 Ken Brown <kbrown@cornell.edu>
4582 * xfns.c (x_in_use): Remove `static' qualifier.
4583 * xterm.h (x_in_use): Declare.
4584 * xgselect.c: Include xterm.h.
4585 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4586 and `display_arg' (bug#9754).
4588 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4590 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4592 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4593 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4595 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4597 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4599 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4600 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4602 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4603 reference to image_cache->refcount.
4604 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4606 2012-05-17 Juri Linkov <juri@jurta.org>
4608 * search.c (Fword_search_regexp, Fword_search_backward)
4609 (Fword_search_forward, Fword_search_backward_lax)
4610 (Fword_search_forward_lax): Move functions to isearch.el
4611 (bug#10145, bug#11381).
4613 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4615 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4617 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4619 * lread.c (init_obarray): Declare Qt and Qnil as special.
4621 2012-05-14 Glenn Morris <rgm@gnu.org>
4623 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4624 Put "libexec" before "bin", for the sake of init_callproc_1.
4626 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4628 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4630 * unexaix.c: Port to more-recent AIX compilers.
4631 (report_error, report_error_1, make_hdr, copy_sym)
4632 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4633 Make arguments const char *, not char *, to avoid violations of C
4634 standard and to fix some AIX warnings reported by Gilles Pion.
4636 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4638 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4639 already have overlays loaded.
4640 (handle_single_display_spec): Before returning without displaying
4641 fringe bitmap, synchronize the bidi iterator with the main display
4642 iterator, by calling iterate_out_of_display_property.
4643 (iterate_out_of_display_property): Detect buffer iteration by
4644 testing that it->string is a Lisp string.
4645 (get_next_display_element): When the current object is exhausted,
4646 and there's something on it->stack, call set_iterator_to_next to
4647 proceed with what's on the stack, instead of returning zero.
4648 (set_iterator_to_next): If called at the end of a Lisp string,
4649 proceed to consider_string_end without incrementing string
4650 position. Don't increment display vector index past the end of
4651 the display vector. (Bug#11417)
4652 (pos_visible_p): Don't report a position visible when move_it_to
4653 stopped at the last line of window, which happens to be scanned
4654 backwards by the bidi iteration. (Bug#11464)
4656 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4658 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4659 and right-margin display specs even if the spec is invalid or we
4660 are on a TTY, and thus unable to display on the fringes.
4661 That's because the text with the property will not be displayed anyway,
4662 so we need to signal to the caller that this is a "replacing"
4663 display spec. This fixes display when the spec is invalid or we
4666 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4668 * unexaix.c (make_hdr): Fix typo in prototype.
4669 This bug broke the build on AIX. Problem reported by Gilles Pion.
4671 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4673 * keyboard.c (kbd_buffer_get_event): Read special events also in
4674 batch mode. (Bug#11415)
4676 2012-05-12 Glenn Morris <rgm@gnu.org>
4678 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4680 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4682 * lisp.mk (lisp): Add newcomment.elc.
4684 2012-05-12 Glenn Morris <rgm@gnu.org>
4686 * Makefile.in (MKDIR_P): New, set by configure.
4687 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4689 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4691 Remove unused function hourglass_started.
4692 * dispextern.h (hourglass_started):
4693 * w32fns.c (hourglass_started):
4694 * xdisp.c (hourglass_started): Remove.
4696 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4698 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4699 Update dependencies.
4701 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4703 * xgselect.c (xg_select): Put maxfds+1 into a var.
4704 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4706 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4708 2012-05-10 Dave Abrahams <dave@boostpro.com>
4710 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4711 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4713 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4715 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4716 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4717 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4718 Initialize xd_registered_buses.
4720 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4722 Untag more efficiently if USE_LSB_TAG.
4723 This is based on a proposal by YAMAMOTO Mitsuharu in
4724 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4725 For an admittedly artificial (nth 8000 longlist) benchmark on
4726 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4727 Emacs's overall text size by 1%.
4728 * lisp.h (XUNTAG): New macro.
4729 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4730 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4731 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4732 * eval.c (Fautoload):
4733 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4734 * frame.h (XFRAME): Use XUNTAG.
4736 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4737 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4738 Remove unportable assumptions about print widths of types like
4740 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4741 intptr_t when converting between pointer and integer, to avoid GCC
4742 warnings about wrong width.
4744 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4746 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4747 stack for each reader_thread, instead of defaulting to 8MB
4748 determined by the linker. This avoids failures in creating
4749 subprocesses on Windows 7, see the discussion in this thread:
4750 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4752 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4754 Fix up display of the *Minibuf-0* buffer in the mini window.
4755 * keyboard.c (read_char): Don't clear the echo area if there's no
4757 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4758 contents of *Minibuf-0*) if there's no message displayed in its stead.
4760 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4762 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4765 2012-05-06 Chong Yidong <cyd@gnu.org>
4767 * lisp.mk (lisp): Update.
4769 2012-05-05 Jim Meyering <meyering@redhat.com>
4771 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4773 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4775 * data.c (PUT_ERROR): New macro.
4776 (syms_of_data): Use it. Add new error type `user-error'.
4777 * undo.c (user_error): New function.
4778 (Fprimitive_undo): Use it.
4779 * print.c (print_error_message): Adjust print style for `user-error'.
4780 * keyboard.c (user_error): New function.
4781 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4783 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4785 Do not limit current-time-string to years 1000..9999.
4786 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4787 (Fcurrent_time_string): Support any year that is supported by the
4788 underlying localtime representation. Don't use asctime, as it
4789 has undefined behavior for years outside the range -999..9999.
4791 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4793 Fix race conditions involving setenv, gmtime, localtime, asctime.
4794 Without this fix, interrupts could mess up code that uses these
4795 nonreentrant functions, since setting TZ invalidates existing
4796 tm_zone or tzname values, and since most of these functions return
4797 pointers to static storage.
4798 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4799 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4800 Grow the critical sections to include not just invoking
4801 localtime/gmtime, but also accessing these functions' results
4802 including their tm_zone values if any, and any related TZ setting.
4803 (format_time_string): Last arg is now struct tm *, not struct tm **,
4804 so that the struct tm is saved in the critical section.
4805 All callers changed. Simplify allocation of initial buffer, partly
4806 motivated by the fact that memory allocation needs to be outside
4807 the critical section.
4809 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4811 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4812 with RESET_INTERVAL.
4814 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4815 Remove duplicated buffer name initialization.
4817 2012-05-02 Jim Meyering <jim@meyering.net>
4819 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4821 * xfns.c (x_window): Use xstrdup (Bug#11375).
4823 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4825 * xdisp.c (pos_visible_p): If already at a newline from the
4826 display string before the 'while' loop, don't walk back the glyphs
4827 from it3.glyph_row. Solves assertion violation when the display
4828 string begins with a newline (egg.el). (Bug#11367)
4830 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4832 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4835 2012-05-01 Glenn Morris <rgm@gnu.org>
4837 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4838 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4839 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4840 All were removed before 23.1.
4842 * dispnew.c: Remove HAVE_LIBNCURSES test;
4843 it is always true on relevant platforms.
4845 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4846 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4848 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4850 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4852 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4853 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4856 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4858 Do not avoid creating empty evaporating overlays (Bug#9642).
4859 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4860 That is, do not delete an evaporating overlay if it becomes
4861 empty after its bounds are adjusted to fit within its buffer.
4862 This fix caused other problems, and I'm reverting it until we get
4863 to the bottom of them.
4865 2012-04-27 Chong Yidong <cyd@gnu.org>
4867 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4869 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4871 * xdisp.c (pos_visible_p): If the window start position is beyond
4872 ZV, start the display from buffer beginning. Prevents assertion
4873 violation in init_iterator when the minibuffer window is scrolled

4926 Do not create empty overlays with the evaporate property (Bug#9642).
4927 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4928 if it becomes empty after its bounds are adjusted to fit within
4929 its buffer. Without this fix, in a nonempty buffer (let ((o
4930 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4931 yields an empty overlay that has the evaporate property, which is
4932 not supposed to happen.

5072 (print_object): Check for cycles even when print-circle is nil and
5073 print-gensym is t, but only check print_depth if print-circle is nil.
5075 2012-04-20 Chong Yidong <cyd@gnu.org>
5077 * process.c (wait_reading_process_output): If EIO occurs on a pty,

5133 New extern decls, to avoid calling undeclared functions.
5134 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5135 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5136 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5137 (NEED_MEM_INSERT): New macro.
5138 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

5206 2012-04-11 Daniel Colascione <dancol@dancol.org>
5208 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5209 against is gone. It's better to use vfork now so that when Cygwin
5210 gains a new, working vfork, we use it automatically (bug#10398).
5212 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5267 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5269 * xdisp.c (set_cursor_from_row): If the display string appears in
5270 the buffer at position that is closer to point than the position
5271 after the display string, display the cursor on the first glyph of
5272 the display string. Fixes cursor display when a 'display' text
5273 property immediately follows invisible text. (Bug#11094)
5275 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5277 composite.c: use 'double' consistently
5278 * composite.c (get_composition_id): Use 'double' consistently
5279 instead of converting 'float' to 'double' and vice versa; this is
5280 easier to understand and avoids a GCC warning.
5282 2012-04-09 Glenn Morris <rgm@gnu.org>
5284 * Makefile.in: Generate leim-list with bootstrap-emacs, in

5329 [!WINDOWSNT]: New macros.
5330 (init_libxml2_functions, libxml2_loaded_p): New functions.
5331 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5332 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5333 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5334 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5336 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5337 Call init_libxml2_functions before calling libxml2 functions.
5338 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5340 * emacs.c: Don't include libxml/parser.h.
5341 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5342 xmlCleanupParser directly.
5344 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5346 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5348 * indent.c (Fvertical_motion): If there is a display string at
5349 point, use it.vpos to compute how many lines to backtrack after

5354 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5355 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5356 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5357 macros related to unification of CJK characters. For the details,
5358 see the discussion following the message here:
5359 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5361 2012-04-04 Chong Yidong <cyd@gnu.org>
5363 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5365 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5367 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5368 instead of alloca. (Bug#11138)
5370 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5372 * w32menu.c (is_simple_dialog): Properly check lisp types.
5375 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5377 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5378 position we get to after a call to move_it_to fails the
5379 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5380 only if we wind up in a string from display property. (Bug#11063)
5382 * window.c (Fdelete_other_windows_internal): Invalidate the row
5383 and column information about mouse highlight, so that redisplay
5384 restores it after reallocating the glyph matrices. (Bug#7464)
5386 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5387 string comes from a `display' text property, use the buffer
5388 position of that property as if we actually saw that position in
5390 (move_it_by_lines): Remove the assertion that
5391 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5392 violated when there's a before-string at the beginning of a line.
5395 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5397 * xdisp.c (append_space_for_newline): If the default face was
5398 remapped, use the remapped face for the appended newline.
5399 (extend_face_to_end_of_line): Use the remapped default face for
5400 extending the face to the end of the line.
5401 (display_line): Call extend_face_to_end_of_line when the default
5402 face was remapped. (Bug#11068)
5404 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5406 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5408 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5410 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5412 2012-03-27 Glenn Morris <rgm@gnu.org>
5414 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5417 2012-03-26 Kenichi Handa <handa@m17n.org>
5419 * dispextern.h (struct glyph): Fix previous change. Change the
5420 bit length of glyphless.ch to 25 (Bug#11082).
5422 2012-03-26 Chong Yidong <cyd@gnu.org>
5424 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5425 (command_loop_1): Use it; inhibit selection update for
5426 handle-select-window too (Bug#8996).
5428 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5430 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5432 2012-03-25 Kenichi Handa <handa@m17n.org>
5434 * dispextern.h (struct glyph): Change the bit length of
5435 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5437 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5439 * s/ms-w32.h (tzname): Include time.h before redirecting to
5440 _tzname. Fixes the MSVC build. (Bug#9960)
5442 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5444 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5447 * xterm.c (XTread_socket): Only modify handling_signal if
5448 !SYNC_INPUT. (Bug#11080)
5450 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5452 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5453 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5454 when fetching a multibyte character consumes more bytes than
5455 CHAR_BYTES returns, due to unification of CJK characters in
5456 string_char. (Bug#11073)
5458 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5460 * process.c (wait_reading_process_output): Handle pty disconnect
5461 by refraining from sending oneself a SIGCHLD (bug#10933).
5463 2012-03-22 Chong Yidong <cyd@gnu.org>
5465 * dispextern.h (struct it): New member string_from_prefix_prop_p.

5476 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5478 * w32proc.c (Fw32_set_console_codepage)
5479 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5484 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5485 to reflect default non-nil value of redisplay-dont-pause.
5487 2012-03-19 Kenichi Handa <handa@m17n.org>
5489 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5490 it fit in a valid range (Bug#11003).
5492 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5494 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5495 that is not from display property, accept the row as a "cursor
5496 row" if one of the string's character has a non-nil `cursor'
5497 property. Fixes cursor positioning when there are newlines in
5498 overlay strings, e.g. in icomplete.el. (Bug#11035)
5500 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5502 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5504 2012-03-12 Chong Yidong <cyd@gnu.org>
5506 * eval.c (inhibit_lisp_code): Rename from
5507 inhibit_window_configuration_change_hook; move from window.c.
5509 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5510 * window.c (run_window_configuration_change_hook)
5511 (syms_of_window): Callers changed.
5513 2012-03-11 Chong Yidong <cyd@gnu.org>

5522 is visible (Bug#10955).
5524 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5526 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5528 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5530 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5531 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5534 2012-03-03 Glenn Morris <rgm@gnu.org>
5536 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5538 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5540 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5541 position past the first glyph_row that ends at ZV. (Bug#10902)
5542 (redisplay_window, next_element_from_string): Fix typos in
5544 (redisplay_window): Pass to move_it_vertically the margin in
5545 pixels, not in screen lines.
5547 2012-03-02 Glenn Morris <rgm@gnu.org>
5549 * buffer.c (buffer-list-update-hook): Doc fix.
5551 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5553 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5554 push_it before setting up the iterator for the first overlay
5555 string, even if we have an empty string loaded.
5556 (next_overlay_string): If there's an empty string on the iterator
5557 stack, pop the stack. (Bug#10903)
5559 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5561 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5562 Suggested by Stefan Monnier in
5563 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5564 * alloc.c (widen_to_Lisp_Object): New static function.
5565 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5566 and widening them to Lisp_Objects. This would work even if
5567 USE_LSB_TAG is defined and wide integers are used, which might
5568 happen in a future version of Emacs.
5570 2012-02-25 Chong Yidong <cyd@gnu.org>
5572 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5575 * xselect.c (Fx_selection_exists_p): Doc fix.
5576 (x_clipboard_manager_save_all): Print an informative message
5577 before saving to clipboard manager.
5579 2012-02-24 Chong Yidong <cyd@gnu.org>
5581 * keyboard.c (process_special_events): Handle all X selection
5582 requests in kbd_buffer, not just the next one (Bug#8869).
5584 2012-02-23 Chong Yidong <cyd@gnu.org>
5586 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5587 call when setting menu-bar-lines and tool-bar-lines parameters.
5588 (unwind_create_frame_1): New helper function.
5590 * window.c (inhibit_window_configuration_change_hook): New var.
5591 (run_window_configuration_change_hook): Obey it.
5592 (syms_of_window): Initialize it.
5594 2012-02-22 Chong Yidong <cyd@gnu.org>
5596 * xterm.c (x_draw_image_relief): Add missing type check for
5597 Vtool_bar_button_margin (Bug#10743).

5601 * fileio.c (Vfile_name_handler_alist): Doc fix.
5603 * buffer.c (Fget_file_buffer): Protect against invalid file
5604 handler return value.
5606 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5608 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5609 when computing $valmask.
5611 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5612 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5613 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5614 It's useless in that case, and it can cause problems on hosts
5615 that allocate halves of EMACS_INT values separately.
5616 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5617 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5618 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5619 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5620 it avoids undefined behavior on hosts where shifting right by more
5621 than the word width has undefined behavior.
5623 2012-02-19 Chong Yidong <cyd@gnu.org>
5625 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5626 (Funhandled_file_name_directory, Ffile_name_as_directory)
5627 (Fdirectory_file_name, Fexpand_file_name)
5628 (Fsubstitute_in_file_name): Protect against invalid file handler
5629 return values (Bug#10845).
5631 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5633 * .gdbinit (pitx): Fix incorrect references to fields of the
5636 2012-02-17 Chong Yidong <cyd@gnu.org>
5638 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5640 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5642 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5643 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5645 2012-02-15 Chong Yidong <cyd@gnu.org>
5647 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5648 marked as special. Also, starting docstrings with * is obsolete.
5650 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5652 * gnutls.c (emacs_gnutls_write): Fix last change.
5654 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

5659 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5661 * keymap.c (Fsingle_key_description): Handle char ranges.
5663 2012-02-12 Chong Yidong <cyd@gnu.org>
5665 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5666 as that creates a dangerous corner case.
5668 * window.c (Fdelete_window_internal): Invalidate the mouse
5669 highlight (Bug#9904).
5671 2012-02-12 Glenn Morris <rgm@gnu.org>
5673 * xselect.c (Fx_own_selection_internal)
5674 (Fx_get_selection_internal, Fx_disown_selection_internal)
5675 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5676 * nsselect.m (Fx_own_selection_internal)
5677 (Fx_disown_selection_internal, Fx_selection_exists_p)
5678 (Fx_selection_owner_p, Fx_get_selection_internal):
5679 Sync docs and argument specs with the xselect.c versions.
5681 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5683 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5685 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5687 * w32select.c (Fx_selection_exists_p): Sync doc string and
5688 argument list with xselect.c. (Bug#10783)

5701 2012-02-07 Chong Yidong <cyd@gnu.org>
5703 * buffer.c (Fbuffer_local_variables)
5704 (buffer_lisp_local_variables): Handle unbound vars correctly;
5705 don't let Qunbound leak into Lisp.
5707 2012-02-07 Glenn Morris <rgm@gnu.org>
5709 * image.c (Fimagemagick_types): Doc fix.
5711 * image.c (imagemagick-render-type): Change it from a lisp object
5712 to an integer. Move the doc here from the lisp manual.

5715 2012-02-06 Chong Yidong <cyd@gnu.org>
5717 * doc.c (store_function_docstring): Avoid applying docstring of
5718 alias to base function (Bug#2603).
5720 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5722 * .gdbinit (pp1, pv1): Remove redundant defines.
5725 2012-02-04 Chong Yidong <cyd@gnu.org>
5727 * nsterm.m: Declare a global (Bug#10694).
5729 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5731 * w32.c (get_emacs_configuration_options):
5732 Include --enable-checking, if specified, in the return value.
5734 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5736 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5737 after rounding frame sizes. (Bug#9723)

5741 * keyboard.c (adjust_point_for_property): Don't position point
5742 before BEGV. (Bug#10696)
5744 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5746 Handle overflow when computing char display width (Bug#9496).
5747 * character.c (char_width): Return EMACS_INT, not int.
5748 (char_width, c_string_width): Check for overflow when
5749 computing the width; this is possible now that individual
5750 characters can have unbounded width. Problem introduced
5751 by merge from Emacs 23 on 2012-01-19.
5753 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5755 * dbusbind.c (Fdbus_register_method): Mention the return value
5756 :ignore in the docstring.
5758 2012-02-02 Glenn Morris <rgm@gnu.org>
5760 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

5768 2012-02-02 Kenichi Handa <handa@m17n.org>
5770 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5771 0, do not call append_composite_glyph.
5773 2012-02-02 Kenichi Handa <handa@m17n.org>
5775 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5777 (x_produce_glyphs): If the component of a composition is a null
5778 string, set it->pixel_width to 1 to avoid zero-width glyph.
5780 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5782 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5783 first 2 arguments are identical. This makes inserting large
5784 output from a subprocess an order of magnitude faster on
5785 MS-Windows, where all sbrk'ed memory is always contiguous.
5787 2012-01-31 Glenn Morris <rgm@gnu.org>
5789 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

6404 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6405 is set, removing the need for VIRT_ADDRESS_VARIES.
6406 (PURE_P): Use a more-efficient implementation that needs just one
6407 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6408 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6409 to 4 (xorl, subq, cmpq, setbe).
6410 * alloc.c (pure): Always extern now, since that's the
6411 VIRT_ADDR_VARIES behavior.
6412 (PURE_POINTER_P): Use a single comparison, not two, for
6413 consistency with the new puresize.h.
6414 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6422 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6423 behave as if the cursor position were at the window margin.
6425 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6426 and the cursor position is out of bounds, behave as if the cursor
6427 position were at the window margin. (Bug#10075)

6457 * dispnew.c (verify_row_hash): Call row_hash for computing the
6458 hash code of a row, instead of duplicating code from xdisp.c.

6496 * image.c (imagemagick_load_image): Fix typo.
6498 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6500 * xdisp.c (display_line): Move the call to
6501 highlight_trailing_whitespace before the call to
6502 compute_line_metrics, since the latter needs to see the final
6503 faces of all the glyphs to compute ROW's hash value.
6504 Fixes assertion violations in row_equal_p. (Bug#10035)
6506 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

6565 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6567 Avoid some portability problems by eschewing 'extern inline' functions.
6568 The trivial performance wins aren't worth the portability hassles; see
6569 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6571 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6573 (window_box_right, window_box_right_offset): Undo previous change,
6574 by removing the "extern"s.
6575 * intervals.c (adjust_intervals_for_insertion)
6576 (adjust_intervals_for_deletion): Undo previous change,
6577 making these static again.
6578 (offset_intervals, temp_set_point_both, temp_set_point)
6579 (copy_intervals_to_string): No longer inline.
6580 * xdisp.c (window_text_bottom_y, window_box_width)

6653 (static_offset_intervals): Remove.
6654 (offset_intervals): Rewrite using the old contents of
6655 static_offset_intervals. The old version didn't conform to C99
6656 because an extern inline function contained a reference to an
6657 identifier with static linkage.

6797 * window.c (temp_output_buffer_show): Don't use
6798 Vtemp_buffer_show_specifiers.
6799 (Vtemp_buffer_show_specifiers): Remove unused variable.
6801 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6803 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6804 past the beginning of the current glyph matrix.
6806 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
6808 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
6809 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6810 HAVE_GTK3 (Bug#9869).
6812 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6813 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6815 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6817 * xterm.c: Declare x_handle_net_wm_state to return int.
6818 (handle_one_xevent): Check if we are iconified but don't have
6819 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6820 (get_current_wm_state): Return non-zero if not hidden,
6821 check for _NET_WM_STATE_HIDDEN (Bug#9893).
6822 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
6823 (x_handle_net_wm_state): Return what get_current_wm_state returns.
6824 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
6826 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6828 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6829 so that this new function doesn't get optimized away by a
6830 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6832 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6834 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6836 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6838 Fix the `xbytecode' command.
6839 * .gdbinit (xprintbytestr): New command.
6840 (xwhichsymbols): Rename from `which'; all callers changed.
6841 (xbytecode): Print the byte-code string as well.
6843 2011-10-29 Kim Storm <storm@cua.dk>
6845 * alloc.c (which_symbols): New function.
6847 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6849 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6852 2011-10-29 Glenn Morris <rgm@gnu.org>
6854 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6855 Not clear what it was for, and it causes various bugs. (Bug#9839)
6857 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6859 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6860 possible random value that matches one of those tested as
6861 condition to clear the mouse face.
6863 2011-10-28 Chong Yidong <cyd@gnu.org>
6865 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6867 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6869 * window.c (make_window): Initialize phys_cursor_on_p.
6871 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6873 * lisp.h (struct Lisp_Symbol): Update comments.
6875 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6877 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6879 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6881 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6882 <oslsachem@gmail.com> for helping to debug this.
6884 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6885 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6886 (g_b_init_get_glyph_outline_w): New static variables.
6887 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6888 (GetGlyphOutlineW_Proc): New typedefs.
6889 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6890 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6892 (w32font_open_internal, compute_metrics):
6893 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6894 instead of calling the "wide" APIs directly.
6896 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6898 * w32.h (syms_of_w32font): Add prototype.
6900 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6902 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6903 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6904 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6905 (Fmove_to_window_line): Doc fix.
6907 2011-10-27 Chong Yidong <cyd@gnu.org>
6909 * process.c (make_process): Set gnutls_state to NULL.
6911 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6912 non-NULL, regardless of GNUTLS_INITSTAGE.
6913 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6914 an error. Set process slots as soon as we allocate them.
6916 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6918 2011-10-27 Chong Yidong <cyd@gnu.org>
6920 * gnutls.c (emacs_gnutls_deinit): New function.
6921 Deallocate credentials structures as well as calling gnutls_deinit.
6922 (Fgnutls_deinit, Fgnutls_boot): Use it.
6924 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6925 (deactivate_process): Call emacs_gnutls_deinit.
6927 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6929 * image.c (x_create_x_image_and_pixmap):
6930 * w32.c (sys_rename, w32_delayed_load):
6931 * w32font.c (fill_in_logfont):
6932 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6934 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6936 * w32fns.c (w32_default_color_map): New function,
6937 extracted from Fw32_default_color_map.
6938 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6940 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6942 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6944 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6946 * keyboard.c (test_undefined): New function (bug#9751).
6947 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6949 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6951 * sysdep.c (init_sys_modes): Fix the check for the controlling
6952 terminal (Bug#6649).
6954 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6956 * dispextern.h (struct bidi_it): New member next_en_type.
6958 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6959 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6960 current character, check also for next_en_type being WEAK_EN.
6961 (bidi_resolve_weak): Don't enter the expensive loop if the current
6962 position is before next_en_pos. Record the bidi type of the first
6963 non-ET, non-BN character we find, in addition to its position.
6964 (bidi_level_of_next_char): Invalidate next_en_type when
6965 next_en_pos is over-stepped.
6967 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6969 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6970 * editfns.c: Rewrite current-time-zone so that it invokes
6971 the equivalent of (format-time-string "%Z") to get the time zone name.
6972 This fixes a bug when the time zone name contains characters that
6973 need converting from the system time locale to Emacs internal format.
6974 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6975 that patch fixed format-time-string to do the conversion, but
6976 I forgot to fix current-time-zone.
6977 (format_time_string): New function, containing most of
6978 what Fformat_time_string used to contain.
6979 (Fformat_time_string): Rewrite in terms of format_time_string.
6980 This doesn't change this function's behavior.
6981 (current-time-zone): Rewrite to use format_time_string.
6982 This fixes the bug reported by Michael Schierl in
6983 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6984 Jason Rumney's 2007-06-07 change worked around this bug, but
6986 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6988 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6990 * xdisp.c (start_display): If the character at POS is displayed
6991 via a display vector, reset IT->current.dpvec_index to zero.
6992 (try_window_reusing_current_matrix): If a line ends in a display
6993 vector or the next line starts in a display vector, continue
6994 redrawing the window even though the character position of
6995 start_row was reached.
6998 2011-10-18 Chong Yidong <cyd@gnu.org>
7000 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7001 with nobreak-char-display too.
7003 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7005 Fix part 3 of bug#9771.
7006 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7007 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7008 non-neutral characters if the current character is a paragraph
7009 separator (a.k.a. Newline). This avoids running the same
7010 expensive loop twice, once when we consume the preceding newline
7011 and the other time when the line actually needs to be displayed.
7012 Avoid the loop when we see neutrals on the base embedding level
7013 following a character whose directionality is the same as the
7014 paragraph's. This avoids running the expensive loop when a line
7015 ends in a long sequence of neutrals, like control characters.
7016 Add assertion against STRONG_AL type. Slightly rearrange code
7017 that determines the type of a neutral given the first non-neutral
7019 (bidi_level_of_next_char): Set next_en_pos to zero when
7020 invalidating its info.
7022 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7024 * xdisp.c (push_display_prop): Determine whether to record string
7025 or buffer position by IT->string, not by IT->method. Allow
7026 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7027 (move_it_vertically_backward): Don't look for character position
7028 immediately after the newline when in a continuation line.
7031 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7033 * window.c (coordinates_in_window): Rewrite and delabelize
7034 vertical border check. (Bug#5357) (Bug#9618)
7036 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7038 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7039 errors in XSetWindowBorder (bug#9310).
7041 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7043 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7044 avoid crash when xmalloc overrun checking is enabled.
7046 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7048 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7049 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7050 cursor motion with <left> and <right> arrow keys.
7052 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7053 some callers set that themselves.
7055 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7057 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7058 display string and the previous row comes from the same string and
7059 is empty. (Bug#9739) (Bug#9738)
7061 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7063 * doc.c (get_doc_string): Encode file name (bug#9735).
7065 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7067 * bidi.c (bidi_level_of_next_char):
7068 * xdisp.c (get_visually_first_element): Remove old incorrect
7069 comments regarding the Unicode Line Separator character.
7071 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7073 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7075 * alloc.c (Fgc_status): Do not access beyond zombies array
7076 boundary if nzombies > MAX_ZOMBIES.
7077 * alloc.c (dump_zombies): Add missing format specifier.
7079 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7081 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7082 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7084 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7085 Some packages use them to denote characters with modifiers.
7087 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7089 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7090 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7091 matching a pp-number. Rename parameter var to var1.
7093 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7095 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7097 2011-10-08 Glenn Morris <rgm@gnu.org>
7099 * callint.c (Fcall_interactively): Give a more explicit error for the
7100 'c' case with a non-character input. (Bug#8479)
7102 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7104 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7106 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7107 lines that are hscrolled on the left.
7109 * dispnew.c (buffer_posn_from_coords): Account for a possible
7110 presence of header-line. (Bug#4426)
7112 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7114 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7115 Don't advertise functionality which we discourage or doesn't work.
7117 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7119 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7120 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7121 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7122 this makes Emacs dump core during garbage collection on rare
7123 occasions. sizeof is obviously inferior to offsetof here, so
7124 stick with offsetof.
7125 (GC_POINTER_ALIGNMENT): New macro.
7126 (mark_memory): Omit 3rd (offset) arg; caller changed.
7127 Don't assume EMACS_INT alignment is the same as pointer alignment.
7129 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7131 * keyboard.c (read_key_sequence_remapped): New var.
7132 (read_key_sequence): Compute remapping in the right buffer.
7133 (command_loop_1): Use read_key_sequence's remapping directly.
7135 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7137 * dired.c (file_name_completion): Don't expand file name.
7138 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7139 before checking file name handler.
7141 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7142 they've been requested explicitly (bug#9591).
7144 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7146 * keymap.c (Fsingle_key_description): Use make_specified_string
7147 instead of build_string to build string from push_key_description.
7150 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7152 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7153 This fixes a Y2038 bug on 64-bit hosts.
7154 * buffer.c (reset_buffer):
7155 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7156 (Fclear_buffer_auto_save_failure):
7157 Use 0, not -1, to represent an unset failure time, since time_t
7158 might not be signed.
7160 Remove dependency on glibc malloc internals.
7161 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7162 Move back here from lisp.h, but with their new implementations.
7163 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7164 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7165 * charset.c (charset_table_init): New static var.
7166 (syms_of_charset): Use it instead of xmalloc. This removes a
7167 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7168 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7169 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7170 Move back to alloc.c.
7171 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7172 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7174 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7176 * nsterm.m (windowDidResize): Call x_set_window_size only when
7177 ns_in_resize is true. Otherwise set pixelwidth/height and
7178 call change_frame_size (Bug#9628).
7180 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7182 Port --enable-checking=all to Fedora 14 x86-64.
7183 * charset.c (syms_of_charset): Also account for glibc malloc's
7184 internal overhead when calculating the initial malloc maximum.
7186 Port --enable-checking=all to Fedora 14 x86.
7187 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7189 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7190 (overrun_check_realloc, overrun_check_free):
7191 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7192 That way, xmalloc returns a properly-aligned pointer even if
7193 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7194 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7195 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7196 into account when calculating the initial malloc maximum.
7197 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7198 Move here from alloc.c, so that charset.c can use it too.
7199 Properly align; the old code wasn't right for common 32-bit hosts
7200 when configured with --enable-checking=all.
7201 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7202 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7204 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7206 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7209 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7211 * xdisp.c (compute_display_string_end): If there's no display
7212 string at CHARPOS, return -1.
7214 * bidi.c (bidi_fetch_char): When compute_display_string_end
7215 returns a negative value, treat the character as a normal
7216 character not covered by a display string. (Bug#9624)
7218 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7220 * lread.c (Fread_from_string): Fix typo in docstring.
7222 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7224 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7225 newline, reseat the iterator instead of bidi-iterating there one
7226 character at a time. (Bug#9610)
7227 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7228 TO_CHARPOS if the bidi iterator is at base embedding level.
7230 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7232 * lread.c (readevalloop): Use correct code for NBSP.
7233 (read1): Likewise. (Bug#9608)
7235 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7237 * dbusbind.c (Fdbus_register_signal): When service is not
7238 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7240 2011-09-25 Glenn Morris <rgm@gnu.org>
7242 * buffer.c (truncate-lines): Doc fix.
7244 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7246 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7247 (Fset_window_next_buffers): Doc fix.
7249 2011-09-24 Glenn Morris <rgm@gnu.org>
7251 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7253 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7255 Fix minor problems found by static checking.
7256 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7257 * indent.c (Fvertical_motion): Fix == vs = typo.
7259 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7261 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7262 Default value is now t. Doc fix.
7264 * indent.c (Fvertical_motion): Compute and apply the overshoot
7265 logic when moving up, not only when moving down. Fix the
7266 confusing name and values of the it_overshoot_expected variable;
7267 logic changes accordingly. (Bug#9254) (Bug#9549)
7269 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7270 CHARPOS is covered by a display string which includes newlines.
7271 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7272 is covered by a display string with embedded newlines.
7274 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7276 * dbusbind.c (Fdbus_register_signal): Add match rule to
7277 Vdbus_registered_objects_table. (Bug#9581)
7278 (Fdbus_register_method, Vdbus_registered_objects_table):
7281 2011-09-24 Jim Meyering <meyering@redhat.com>
7283 do not ignore write error for any output size
7284 The previous change was incomplete.
7285 While it makes emacs --batch detect the vast majority of stdout
7286 write failures, errors were still ignored whenever the output size is
7287 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7288 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7289 && echo FAIL: ignored write error
7290 FAIL: ignored write error
7291 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7292 && echo FAIL: ignored write error
7293 FAIL: ignored write error
7294 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7296 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7298 * emacs.c (Fkill_emacs): In noninteractive mode exit
7299 non-successfully if a write error occurred on stdout. (Bug#9574)
7301 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7303 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7306 * dispextern.h (struct it): Update the comment documenting what
7309 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7311 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7312 a display string, extend search for cursor position to end of row.
7313 (find_row_edges): If the row ends in a newline from a display
7314 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7315 Handle the case of a display string with multiple newlines.
7316 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7317 non-empty line. Fixes confusing cursor motion with arrow keys at
7318 the beginning of a line that starts with whitespace.
7320 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7322 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7325 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7327 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7330 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7332 * xdisp.c (display_line): Record maximum and minimum buffer
7333 positions even if no glyphs were produced (e.g., by a zero-width
7334 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7335 buffer positions that will be removed from the glyph row because
7337 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7338 column is beyond frame width: don't subtract 1 "pixel" when
7339 computing width of the stretch.
7340 (reseat_at_next_visible_line_start): Undo the change made on
7341 2011-09-17 that saved paragraph information and restored it after
7342 the call to `reseat'. (Bug#9545)
7344 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7346 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7347 and turn window cursor on if cleared (Bug#9415).
7349 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7351 * search.c (boyer_moore): Take unibyte characters from pattern
7352 literally. (Bug#9458)
7354 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7356 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7358 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7360 Fix minor problem found by static checking.
7361 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7362 initialized, to pacify gcc -Wuninitialized.
7364 * fileio.c: Report proper errno when syscall falls.
7365 (Finsert_file_contents): Save and restore errno,
7366 so that report_file_error outputs the correct diagnostic.
7367 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7369 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7371 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7373 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7375 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7376 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7378 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7380 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7381 about the current paragraph and restore it after the call to reseat.
7383 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7384 (bidi_find_paragraph_start): Search back for paragraph beginning
7385 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7386 (bidi_move_to_visually_next): Only trigger paragraph-related
7387 computations when the last character is a newline or at EOB, not
7388 just any NEUTRAL_B. (Bug#9470)
7390 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7391 truncated lines if point is covered by a display string. (Bug#9524)
7393 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7395 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7396 (cons_to_x_long): New function.
7397 (lisp_data_to_selection_data): Use it. Correct the test for
7398 short-versus-long data; it was negated. Break out of vector
7399 loop, for efficiency, when a long datum is discovered.
7401 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7403 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7405 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7407 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7408 GCC PR/17406) by declaring this function with external scope.
7410 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7412 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7413 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7415 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7417 * editfns.c (Fformat): Correctly handle text properties on "%%".
7419 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7421 * xterm.c (x_draw_composite_glyph_string_foreground):
7422 * w32term.c (x_draw_composite_glyph_string_foreground):
7423 * term.c (encode_terminal_code):
7424 * composite.c (composition_update_it, get_composition_id):
7425 * xdisp.c (get_next_display_element)
7426 (fill_composite_glyph_string): Add comments about special meaning
7427 of TAB characters in a composition.
7429 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7431 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7432 This occurs when processing a multibyte format.
7433 Problem reported by Wolfgang Jenker.
7435 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7437 * xdisp.c (try_cursor_movement): Only check for exact match if
7438 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7440 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7442 Remove unused external symbols.
7443 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7444 * xdisp.c (calc_pixel_width_or_height): Now static.
7445 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7446 * indent.c (check_display_width):
7447 * w32term.c: Fix comment to match code.
7448 * xterm.c, xterm.h (x_catching_errors): Remove.
7450 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7452 * xselect.c: Use signed conversions more consistently (Bug#9498).
7453 (selection_data_to_lisp_data): Assume incoming selection data are
7454 signed integers, not unsigned. This is to be consistent with
7455 outgoing selection data, which was modified to use signed integers
7456 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7457 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7458 expects long, not unsigned long.
7460 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7462 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7463 computation of loop end. Reported by Johan Bockgård
7466 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7468 * frame.c (Fother_visible_frames_p): Function deleted.
7470 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7472 * indent.c (compute_motion): Process display vector front to back
7473 rather than the other way around. (Bug#2496)
7475 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7477 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7479 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7481 * minibuf.c (Fread_from_minibuffer): Doc fix.
7483 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7485 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7486 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7488 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7490 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7491 value for non-existent files.
7493 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7495 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7496 set its "size" to -1. This will set the modtime_size field of
7497 the corresponding buffer to -1, which is what
7498 verify-visited-file-modtime expects for files that do not exist.
7501 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7503 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7505 * lisp.h: ... from here. push_key_description is no longer
7506 defined in keyboard.c, so its declaration should not be in
7507 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7508 logically belongs with push_key_description.
7510 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7512 * buffer.h: Include <sys/types.h> instead of <time.h>.
7513 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7514 Problem reported by Herbert J. Skuhra.
7516 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7518 * xml.c (parse_region): Make the parsing work for
7519 non-comment-starting XML files again (bug#9144).
7521 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7523 * image.c (gif_load): Fix calculation of bottom and right corner.
7526 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7528 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7529 redisplay in small windows.
7531 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7533 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7535 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7537 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7538 Operate on live windows only.
7540 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7542 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7544 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7546 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7547 only under bidi iteration.
7549 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7551 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7553 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7555 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7556 Without this fix, the command to link temacs failed due to an
7557 undefined symbol __builtin_isnan. This is because
7558 /usr/include/iso/math_c99.h #defines isnan(x) to
7559 __builtin_isnan(x), but the bundled gcc, which identifies itself
7560 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7562 * floatfns.c (isnan): #undef, and then #define to a clone of
7564 (Fisnan): Always define, since it's always available now.
7565 (syms_of_floatfns): Always define isnan at the Lisp level.
7567 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7569 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7571 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7573 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7574 The previous code assumed that file offsets (off_t values) fit in
7575 EMACS_INT variables, which is not true on typical 32-bit hosts.
7576 The code messed up by falsely reporting buffer overflow in cases
7577 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7578 when "big" contains more than 2**29 bytes, even though this
7579 inserts just one byte and does not overflow the buffer.
7580 (Finsert_file_contents): Store file offsets as off_t
7581 values, not as EMACS_INT values. Check for overflow when
7582 converting between EMACS_INT and off_t. When checking for
7583 buffer overflow or for overlap, take the offsets into account.
7584 Don't use EMACS_INT for small values where int suffices.
7585 When checking for overlap, fix a typo: ZV was used where
7586 ZV_BYTE was intended.
7587 (Fwrite_region): Don't assume off_t fits into 'long'.
7588 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7590 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7592 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7594 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7596 sprintf-related integer and memory overflow issues (Bug#9412).
7598 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7599 (esprintf, exprintf, evxprintf): New functions.
7600 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7601 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7602 (modify_event_symbol): Do not assume that the length of
7603 name_alist_or_stem is safe to alloca and fits in int.
7604 (Fexecute_extended_command): Likewise for function name and binding.
7605 (Frecursion_depth): Wrap around reliably on integer overflow.
7606 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7607 since some callers pass EMACS_INT values.
7608 (Fsingle_key_description): Don't crash if symbol name contains more
7609 than MAX_ALLOCA bytes.
7610 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7611 (get_minibuffer): Arg is now EMACS_INT, not int.
7612 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7613 (esprintf, exprintf, evxprintf): New decls.
7614 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7616 * dbusbind.c (signature_cat): New function.
7617 (xd_signature, Fdbus_register_signal):
7618 Do not overrun buffer; instead, report string overflow.
7620 * dispnew.c (add_window_display_history): Don't overrun buffer.
7621 Truncate instead; this is OK since it's just a log.
7623 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7624 even if the time zone offset is outlandishly large.
7625 Don't mishandle offset == INT_MIN.
7627 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7628 when creating daemon; the previous buffer-overflow check was incorrect.
7630 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7631 which has the guts of the old verror function.
7633 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7634 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7636 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7637 (font_unparse_xlfd): Don't blindly alloca long strings.
7638 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7639 fits in int, when using sprintf. Use single snprintf to count
7640 length of string rather than counting it via multiple sprintfs;
7641 that's simpler and more reliable.
7642 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7643 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7644 sprintf, in case result does not fit in int.
7646 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7647 (fontset_from_font): Print it.
7649 * frame.c (tty_frame_count): Now printmax_t, not int.
7650 (make_terminal_frame, set_term_frame_name): Print it.
7651 (x_report_frame_params): In X, window IDs are unsigned long,
7652 not signed long, so print them as unsigned.
7653 (validate_x_resource_name): Check for implausibly long names,
7654 and don't assume name length fits in 'int'.
7655 (x_get_resource_string): Don't blindly alloca invocation name;
7656 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7659 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7660 (xg_check_special_colors, xg_set_geometry):
7661 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7663 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7664 Use esprintf, not sprintf, in case result does not fit in int.
7666 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7667 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7668 it as a large positive number.
7669 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7670 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7672 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7673 in case result does not fit in int.
7675 * print.c (float_to_string): Detect width overflow more reliably.
7676 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7677 buffer overrun. Don't assume list length fits in 'int'. Treat
7678 print length of 0 as 0, not as infinity; to be consistent with other
7679 uses of print length in this function. Don't overflow print length
7680 index. Don't assume hash table size fits in 'long', or that
7681 vectorlike size fits in 'unsigned long'.
7683 * process.c (make_process): Use printmax_t, not int, to format
7684 process-name gensyms.
7686 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7688 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7689 to avoid potential buffer overrun.
7691 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7692 if X resource line is longer than 512 bytes.
7694 * xfns.c (x_window): Make sprintf buffer a bit bigger
7695 to avoid potential buffer overrun.
7697 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7699 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7701 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7703 Integer overflow fixes for scrolling, etc.
7704 Without these, Emacs silently mishandles large integers sometimes.
7705 For example, "C-u 4294967297 M-x recenter" was treated as if
7706 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7708 * xdisp.c (try_window_id): Check Emacs fixnum range before
7709 converting to 'int'.
7711 * window.c (window_scroll_line_based, Frecenter):
7712 Check that an Emacs fixnum is in range before assigning it to 'int'.
7713 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7714 values converted from Emacs fixnums.
7715 (Frecenter): Don't wrap around a line count if it is out of 'int'
7716 range; instead, treat it as an extreme value.
7717 (Fset_window_configuration, compare_window_configurations):
7718 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7720 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7721 that can exceed INT_MAX. Check that EMACS_INT value is in range
7722 before assigning it to the (possibly-narrower) index.
7723 (match_limit): Don't assume that a fixnum can fit in 'int'.
7725 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7728 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7729 (Fvertical_motion): Don't wrap around LINES values that don't fit
7730 in 'int'. Instead, treat them as extreme values. This is good
7731 enough for windows, which can't have more than INT_MAX lines anyway.
7733 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7735 * Require libxml/parser.h to avoid compilation warning.
7737 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7739 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7740 since this reportedly can destroy thread storage.
7742 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7744 * syntax.c (find_defun_start): Update all cache variables if
7745 exiting early (Bug#9401).
7747 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7749 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7751 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7752 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7753 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7755 * term.c (tty_append_glyph): New function.
7756 (produce_stretch_glyph): Static function and its prototype deleted.
7758 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7761 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7763 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7764 when checking :margin (Bug#9390).
7765 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7766 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7767 so that the name doesn't mislead. All uses changed.
7769 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7771 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7774 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7776 * xdisp.c (move_it_to): Don't bail out early when reaching
7777 position beyond to_charpos, if we are scanning backwards.
7778 (move_it_vertically_backward): When DY == 0, make sure we get to
7779 the first character in the line after the newline.
7781 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7783 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7784 (ccl_driver): Do not generate an out-of-range pointer.
7785 (Fccl_execute_on_string): Remove unnecessary check for
7786 integer overflow, noted by Stefan Monnier in
7787 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7788 Remove a FIXME that didn't need fixing.

7795 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7797 Integer and memory overflow issues (Bug#9196).
7799 * doc.c (get_doc_string): Rework so that
7800 get_doc_string_buffer_size is the actual buffer size, rather than
7801 being 1 less than the actual buffer size; this makes xpalloc more
7804 * image.c (x_allocate_bitmap_record, cache_image):
7805 * xselect.c (Fx_register_dnd_atom):
7806 Simplify previous changes by using xpalloc.
7808 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7809 since either will do and ptrdiff_t is convenient with xpalloc.
7811 * charset.c (charset_table_size)
7812 (struct charset_sort_data.priority): Now ptrdiff_t.
7813 (charset_compare): Don't overflow if priorities differ greatly.
7814 (Fsort_charsets): Don't assume list length fits in int.
7815 Check for size-calculation overflow when allocating sort data.
7816 (syms_of_charset): Allocate an initial charset table that is
7817 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7819 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7821 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7822 The actual value is always <= INT_MAX, and leaving it unsigned made
7823 overflow checking harder.
7825 * dispextern.h (struct glyph_matrix.rows_allocated)
7826 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7827 with xpalloc. The values are still always <= INT_MAX.
7829 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7831 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7832 (SAFE_NALLOCA): New macro.
7834 * region-cache.c (struct boundary.pos, find_cache_boundary)
7835 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7836 (set_cache_region, invalidate_region_cache)
7837 (revalidate_region_cache, know_region_cache, region_cache_forward)
7838 (region_cache_backward, pp_cache):
7839 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7840 so that ptrdiff_t * can be passed to xpalloc.
7841 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7842 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7843 (pp_cache): Don't assume cache_len fits in int.
7844 * region-cache.h: Adjust extern decls to match.

7850 (xnmalloc, xnrealloc, xpalloc): New functions.
7852 * bidi.c (bidi_shelve_header_size): New constant.
7853 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7854 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7856 * bidi.c (bidi_cache_shrink):
7857 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7859 Don't update size of array until after memory allocation succeeds,
7860 because xmalloc/xrealloc may not return.
7861 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7862 now that we have proper integer overflow checking.
7863 (record_overlay_string, overlay_strings): Catch overflows when
7864 calculating size of overlay_str_buf.
7866 * callproc.c (Fcall_process): Check for size overflow when
7867 calculating size of args2.
7868 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7869 Normally we prefer signed values, but sticking with ptrdiff_t would
7870 require adding more-complicated checks.
7872 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7873 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7874 Redo buffer-overflow calculations to avoid integer overflow.
7875 Add a FIXME comment where memory seems to be over-allocated.
7877 * character.c (Fstring): Check for size-calculation overflow.
7879 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7880 unnecessary integer overflow. Check for size overflow.

7883 * composite.c (get_composition_id): Check for overflow in glyph
7884 length calculations.
7886 Integer and memory overflow fixes for display code.

7888 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7889 (scrolling_window): Check for overflow in size calculations.
7890 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7902 (get_doc_string): Check for size calculation overflow.
7903 Don't update size until allocation succeeds.
7904 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7905 EMACS_INT, where ptrdiff_t will do.
7906 (Fsubstitute_command_keys): Check for string overflow.
7908 * editfns.c (set_time_zone_rule): Don't assume environment length
7910 (message_length): Now ptrdiff_t, not int.
7911 (Fmessage_box): Don't update size until allocation succeeds.
7912 Don't assume message length fits in int.
7913 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7915 * emacs.c (main): Do not reallocate argv, since there is a null at
7916 the end that can be overwritten, and this way there's no need to
7917 worry about size-calculation overflow.
7918 (sort_args): Check for size-calculation overflow.
7920 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7922 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7924 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7925 (x_set_scroll_bar_width, x_figure_window_size):
7926 Check for integer overflow.
7927 (x_set_alpha): Do not assume XINT fits in int.
7929 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7930 This is for the members text_lines, text_cols, total_lines, total_cols,
7931 where the system imposes an 'int' limit.
7933 * fringe.c (Fdefine_fringe_bitmap):
7934 Don't update size until alloc works.
7936 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7937 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7939 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7940 Check for size-calculation overflow.
7941 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7942 do, as we prefer signed integers.
7943 (id_to_widget.max_size, id_to_widget.used)
7944 (xg_store_widget_in_map, xg_remove_widget_from_map)
7945 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7946 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7947 Use and return ptrdiff_t, not int.
7948 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7949 * gtkutil.h: Change prototypes to match the above.
7951 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7952 are duplicate now that they've been promoted to lisp.h.
7953 (x_allocate_bitmap_record, x_alloc_image_color)
7954 (make_image_cache, cache_image, xpm_load):

7965 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7966 Use ptrdiff_t, not int, to count maps.

7996 (Fset_match_data): Don't assume list lengths fit in 'int'.
7998 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7999 for command line length. Do not attempt to address one before the

8005 (encode_terminal_code, calculate_costs): Check for size
8006 calculation overflow.

8030 Check for size calculation overflow.
8031 (cache_face): Treat size calculation overflows as if they were
8032 memory exhaustion (the usual treatment), rather than aborting.
8034 * xfns.c (x_encode_text, x_set_name_internal)
8035 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8036 sizes, since they can exceed INT_MAX in size. Check for size

8040 (xg_select): Check for size calculation overflow.
8041 Don't update size until alloc done.
8043 * xrdb.c (get_environ_db): Don't assume path length fits in int,

8047 (X_LONG_MIN): New macros.
8048 Use them to make the following changes clearer.
8049 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

8051 future maintainers not to raise the value too much later.
8052 (SELECTION_QUANTUM): Remove, replacing with ...
8053 (selection_quantum): ... new function, which avoids overflow.
8055 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

8064 Redo calculations to avoid overflow.
8065 (x_reply_selection_request): When sending hint, ceiling it at
8066 X_LONG_MAX rather than relying on wraparound overflow to send

8069 (lisp_data_to_selection_data, x_property_data_to_lisp):
8070 Check for size-calculation overflow.

8073 Don't store size until memory allocation succeeds.
8074 (x_get_window_property): Plug memory leak on memory exhaustion.
8075 Don't double-block input; malloc is safe here. Don't assume 2**34
8076 - 4 fits in unsigned long. Add an xassert to check
8077 XGetWindowProperty overflow. Be more careful about overflow
8078 calculations, and distinguish size from memory overflow better.
8079 (receive_incremental_selection): When tracing, don't assume
8080 unsigned int is less than INT_MAX.
8081 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8082 harmful) conversions of unsigned short to int.
8083 (lisp_data_to_selection_data): Don't assume that integers
8084 in the range -65535 through -1 fit in an X unsigned short.
8085 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8086 result parameters unless successful. Rely on cons_to_unsigned
8087 to report problems with elements; the old code wasn't right anyway.
8088 (x_check_property_data): Check for int overflow; we cannot use
8089 a wider type due to X limits.
8090 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8122 * lisp.h (hash_lookup, hash_put):
8123 * minibuf.c (Ftest_completion):
8124 Use ptrdiff_t for hash table indexes, not int (which is too
8125 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8126 32-bit --with-wide-int hosts).
8128 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8129 Add a FIXME comment about memory leaks.

8136 Use sanitize_char_width to avoid undefined and/or bad behavior
8137 with outlandish widths.
8138 * character.h (sanitize_tab_width): Rename from sanitize_width,
8139 now that we have two such functions. All uses changed.
8140 (sanitize_char_width): New inline function.

8164 (make_lispy_movement): Use same integer type in forward decl
8165 that is used in the definition.
8166 (read_key_sequence, keyremap_step):
8167 Change bufsize argument back to int, undoing my 2011-03-30 change.
8168 We prefer signed types, and int is wide enough here.
8169 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8170 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8171 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8172 length, not size_t. Use ptrdiff_t for index, not int.
8173 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8174 possibility of integer overflow.
8176 Overflow, signedness and related fixes for images.

8201 (png_load, gif_load, svg_load_image):
8202 Prefer int to unsigned where either will do.
8203 (tiff_handler): New function, combining the cores of the
8204 old tiff_error_handler and tiff_warning_handler.
8205 This function is rewritten to use vsnprintf and thereby avoid
8206 stack buffer overflows. It uses only the features of vsnprintf
8207 that are common to both POSIX and native Microsoft.
8208 (tiff_error_handler, tiff_warning_handler): Use it.
8209 (tiff_load, gif_load, imagemagick_load_image):
8210 Don't assume :index value fits in 'int'.
8211 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

8213 the integer types that MagickCropImage accepts. Don't assume
8214 Vimagemagick_render_type has a nonnegative value. Don't assume
8215 size_t fits in 'long'.
8216 (gs_load): Use printmax_t to print the widest integers possible.

8230 (handle_single_display_spec): If the display spec is of the form
8231 `(space ...)', and specifies display in the text area, return 2
8233 (try_cursor_movement): Check for the need to scroll more
8234 accurately, and prefer exact match for point under bidi.
8235 Don't advance `row' beyond the last row of the window.
8237 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8238 into disp_prop; all users changed.

8256 positioning on the newline at EOL of R2L text within L2R
8257 paragraph, and vice versa.
8258 (try_cursor_movement): Check continued rows, in addition to
8259 continuation rows. Fixes unwarranted scroll when point enters a
8260 continued line of R2L text within an L2R paragraph, or vice versa.
8261 (cursor_row_p): Consider the case of point being equal to
8262 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8263 from the end of a short line to the beginning of a continued line
8264 of R2L text within L2R paragraph.
8265 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8266 composed characters.
8268 * bidi.c (bidi_check_type): Use xassert.
8269 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p

8281 2011-08-22 Kenichi Handa <handa@m17n.org>
8283 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8284 extra slot even if the purpose is char-code-property-table.
8286 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8288 * xdisp.c (redisplay_window): When computing centering_position,
8289 account for the height of the header line. (Bug#8874)
8291 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8292 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8293 candidate is selected by the mouse, and that candidate has a
8294 composed character under the mouse.
8296 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8297 coordinates reported by pos-visible-in-window-p for a composed
8298 character in column zero.

8308 composed buffer positions.
8310 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8312 * image.c (gif_load): Don't assume that each subimage has the same
8313 dimensions as the base image. Handle disposal method that is
8314 "undefined" by the gif spec (Bug#9335).
8316 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8318 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8323 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8324 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8325 from an Org mode buffer to a Speedbar frame.
8327 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8328 a composition, take its buffer position from IT->cmp_it.charpos.
8329 Fixes cursor positioning at the beginning of a line that begins
8330 with a composed character.
8332 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8334 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8335 character bidirectional type, use STRONG_L instead. Fixes crashes
8336 in a buffer produced by `describe-categories'.
8338 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8339 members before the level stack, so they would be saved and
8340 restored when copying iterator state. Fixes incorrect reordering
8341 around TABs covered by display properties.
8343 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8345 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8476 buffer/string position, to be restored by pop_it. Fix flags in
8477 the iterator structure wrt the object coming from a display
8478 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8479 properties. (Bug#9284)

8538 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8539 amount allocated this far in `bidi_cache_total_alloc'.
8540 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if

8680 * nsterm.h: Add declaration for ns_draw_text_decoration.
8682 * nsterm.m (ns_draw_text_decoration): New function for drawing
8683 underline, overline, and strike-through.
8684 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8685 ns_draw_text_decoration. Change treatment of cursor drawing to
8686 accommodate underlining, etc.
8688 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8690 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8693 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8695 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8696 Without this fix, if a signal arrives just after memory fills up,
8697 'malloc' might be invoked reentrantly.
8699 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8700 In other words, assume that every image size is allowed, on non-X
8701 hosts. This assumption is probably wrong, but it lets Emacs compile.
8703 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8705 * regex.c (re_iswctype): Convert return values to boolean.
8707 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8709 * xdisp.c (compute_display_string_pos): Don't use cached display
8710 string position if the buffer had its restriction changed.
8713 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8715 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8717 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8719 Integer signedness and overflow and related fixes. (Bug#9079)
8721 * bidi.c: Integer size and overflow fixes.
8722 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8723 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8724 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8725 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8726 (bidi_find_other_level_edge):
8727 Use ptrdiff_t instead of EMACS_INT where either will do.
8728 This works better on 32-bit hosts configured --with-wide-int.
8729 (bidi_cache_ensure_space): Check for size-calculation overflow.
8730 Use % rather than repeated addition, for better worst-case speed.
8731 Don't set bidi_cache_size until after xrealloc returns, because it
8733 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8734 (bidi_cache_ensure_space): Also check that the bidi cache size
8735 does not exceed that of the largest Lisp string or buffer. See Eli
8736 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8738 * alloc.c (__malloc_size_t): Remove.
8739 All uses replaced by size_t. See Andreas Schwab's note
8740 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8742 * image.c: Improve checking for integer overflow.
8743 (check_image_size): Assume that f is nonnull, since
8744 it is always nonnull in practice. This is one less thing to
8745 worry about when checking for integer overflow later.
8746 (x_check_image_size): New function, which checks for integer
8747 overflow issues inside X.
8748 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8749 This removes the need for a memory_full check.
8750 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8751 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8752 (xbm_read_bitmap_data): Change locals back to 'int', since
8753 their values must fit in 'int'.
8754 (xpm_load_image, png_load, tiff_load):
8755 Invoke x_create_x_image_and_pixmap earlier,
8756 to avoid much needless work if the image is too large.
8757 (tiff_load): Treat overly large images as if
8758 x_create_x_image_and_pixmap failed, not as malloc failures.
8759 (gs_load): Use x_check_image_size.
8761 * gtkutil.c: Omit integer casts.
8762 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8763 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8765 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8767 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8768 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8769 would wrongly return t on a 64-bit host.
8771 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8772 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8773 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8774 and therefore cause GCC to emit a bogus diagnostic in some cases.
8776 * image.c: Integer signedness and overflow and related fixes.
8777 This is not an exhaustive set of fixes, but it's time to
8778 record what I've got.
8779 (lookup_pixel_color, check_image_size): Remove redundant decls.
8780 (check_image_size): Don't assume that arbitrary EMACS_INT values
8781 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8782 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8783 (tiff_load, imagemagick_load_image):
8784 Check for overflow in size calculations.
8785 (x_create_x_image_and_pixmap): Remove unnecessary test for
8786 xmalloc returning NULL; that can't happen.
8787 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8788 (xpm_color_bucket): Use better integer hashing function.
8789 (xpm_cache_color): Don't possibly over-allocate memory.
8790 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8791 (gif_memory_source):
8792 Use ptrdiff_t, not int or size_t, to record sizes.
8793 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8794 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8795 either works, as we prefer signed integers.
8796 (tiff_read_from_memory, tiff_write_from_memory):
8797 Return tsize_t, not size_t, since that's what the TIFF API wants.
8798 (tiff_read_from_memory): Don't fail simply because the read would
8799 go past EOF; instead, return a short read.
8800 (tiff_load): Omit no-longer-needed casts.
8801 (Fimagemagick_types): Don't assume size fits into 'int'.
8803 Improve hashing quality when configured --with-wide-int.
8804 * fns.c (hash_string): New function, taken from sxhash_string.
8805 Do not discard information about ASCII character case; this
8806 discarding is no longer needed.
8807 (sxhash-string): Use it. Change sig to match it. Caller changed.
8808 * lisp.h: Declare it.
8809 * lread.c (hash_string): Remove, since we now use fns.c's version.
8810 The fns.c version returns a wider integer if --with-wide-int is
8811 specified, so this should help the quality of the hashing a bit.
8813 * emacs.c: Integer overflow minor fix.
8814 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8815 Define only if GNU_LINUX.
8816 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8818 * dispnew.c: Integer signedness and overflow fixes.
8819 Remove unnecessary forward decls, that were a maintenance hassle.
8820 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8822 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8823 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8824 (prepare_desired_row, line_draw_cost):
8825 Use int, not unsigned, where either works.
8826 (save_current_matrix, restore_current_matrix):
8827 Use ptrdiff_t, not size_t, where either works.
8828 (init_display): Check for overflow more accurately, and without
8829 relying on undefined behavior.
8831 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8832 Remove, replacing with the new symbols in lisp.h. All uses changed.
8833 * fileio.c (make_temp_name):
8834 * filelock.c (lock_file_1, lock_file):
8835 * xdisp.c (message_dolog):
8836 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8837 Use pMd etc. instead.
8838 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8839 replacing the pWIDE etc. symbols removed from editfns.c.
8841 * keyboard.h (num_input_events): Now uintmax_t.
8842 This is (very slightly) less likely to mess up due to wraparound.
8845 * buffer.c: Integer signedness fixes.
8846 (alloc_buffer_text, enlarge_buffer_text):
8847 Use ptrdiff_t rather than size_t when either will do, as we prefer
8850 * alloc.c: Integer signedness and overflow fixes.
8851 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8852 (__malloc_size_t): Default to size_t, not to int.
8853 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8854 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8855 Prefer ptrdiff_t to size_t when either would do, as we prefer
8857 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8858 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8859 Now const. Initialize with values that are in range even if char
8861 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8862 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8863 These functions do the right thing with sizes > 2**32.
8864 (check_depth): Now ptrdiff_t, not int.
8865 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8866 Adjust to new way of storing sizes. Check for size overflow bugs
8868 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8869 slightly wrong anyway, as it missed one instance of
8870 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8871 (refill_memory_reserve): Omit needless cast to size_t.
8872 (mark_object_loop_halt): Mark as externally visible.
8874 * xselect.c: Integer signedness and overflow fixes.
8875 (Fx_register_dnd_atom, x_handle_dnd_message):
8876 Use ptrdiff_t, not size_t, since we prefer signed.
8877 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8878 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8879 x_dnd_atoms_size and x_dnd_atoms_length.
8881 * doprnt.c: Prefer signed to unsigned when either works.
8883 * doprnt.c (doprnt):
8885 * xdisp.c (vmessage):
8886 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8887 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8888 prefer signed arithmetic to avoid comparison confusion.
8889 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8890 but is a bit tricky.
8892 Assume freestanding C89 headers, string.h, stdlib.h.
8893 * data.c, doprnt.c, floatfns.c, print.c:
8894 Include float.h unconditionally.
8895 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8896 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8897 * regex.c: Likewise for stddef.h, string.h.
8898 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8899 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8900 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8901 (STDC_HEADERS): Remove obsolete defines.
8902 * sysdep.c: Include limits.h unconditionally.
8904 Assume support for memcmp, memcpy, memmove, memset.
8905 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8906 * regex.c (memcmp, memcpy):
8907 Remove; we assume C89 now.
8909 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8910 (__malloc_safe_bcopy): Remove; no longer needed.
8912 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8913 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8914 well either way, and we prefer signed to unsigned.
8916 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8918 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8919 closes the connection while we're reading (bug#9182).
8921 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8923 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8924 are specified (Bug#9168).
8926 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8928 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8929 Found by GCC static checking and --with-wide-int on a 32-bit host.
8931 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8933 * xdisp.c (compute_display_string_pos): Fix logic of caching
8934 previous display string position. Initialize cached_prev_pos to
8935 -1. Fixes slow-down at the beginning of a buffer.
8937 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8939 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8940 for attrs[LFACE_FONTSET_INDEX].
8942 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8944 * xml.c (parse_region): Remove unused local
8945 that was recently introduced.
8947 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8949 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8950 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8952 * xdisp.c (move_it_in_display_line_to): Record the best matching
8953 position for TO_CHARPOS while scanning the line, and restore it on
8954 exit if none of the characters scanned was an exact match.
8955 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8956 when exact match is impossible due to invisible text, and the
8957 lines are truncated.
8959 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8961 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8964 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8966 Fix a significant slow-down of cursor motion with C-n, C-p,
8967 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8968 auto-repeat under bidi redisplay in fontified buffers.
8969 * xdisp.c (compute_stop_pos_backwards): New function.
8970 (next_element_from_buffer): Call compute_stop_pos_backwards to
8971 find a suitable prev_stop when we find ourselves before
8973 (reseat): Don't look for prev_stop, as that could mean a very long
8975 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8976 <cached_disp_overlay_modiff>: Cache for last found display string
8978 (compute_display_string_pos): Return the cached position if asked
8979 about the same buffer in the same area of character positions, and
8980 the buffer wasn't changed since the time the display string
8981 position was cached.
8983 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8985 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8986 is an integer, which is important for empty lines. (Bug#9149)
8988 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8990 * frame.c (Fmodify_frame_parameters): In tty case, update the
8991 default face if necessary (Bug#4238).
8993 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8995 * editfns.c (Fstring_to_char): No need to explain what a character
8996 is in the docstring (Bug#6576).
8998 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9000 * xml.c (parse_region): Make sure we always return a tree.
9002 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9004 * xml.c (parse_region): If a document contains only comments,
9007 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9009 * xml.c (make_dom): Return comments, too.
9011 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9014 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9015 and the surrounding thread.
9016 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9017 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9018 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9020 * s/openbsd.h (BROKEN_SIGIO): Define.
9021 * unexelf.c (unexec) [__OpenBSD__]:
9022 Don't update the .mdebug section of the Alpha COFF symbol table.
9024 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9026 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9029 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9031 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9032 This fixes some race conditions on the permissions of any newly
9035 * alloc.c (valid_pointer_p): Use pipe, not open.
9036 This fixes some permissions issues when debugging.
9038 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9039 If fchown fails to set both uid and gid, try to set just gid,
9040 as that is sometimes allowed. Adjust the file's mode to eliminate
9041 setuid or setgid bits that are inappropriate if fchown fails.
9043 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9045 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9046 to compare Lisp_Objects.
9047 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9048 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9049 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9051 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9053 * lread.c (read_integer): Unread even EOF character.
9054 (read1): Likewise. Properly record start position of symbol.
9056 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9057 symbol character follows.
9059 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9061 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9062 This works around a problem with the previous change to Fcopy_file.
9063 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9064 and without this change, GCC might complain about discarding
9065 fchown's return value.
9067 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9069 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9071 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9073 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9075 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9077 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9078 it's used from the C level.
9080 * process.c: Use the same condition for POLL_FOR_INPUT in both
9081 keyboard.c and process.c (bug#1858).
9083 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9085 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9086 (Fgnutls_boot): Use it.
9088 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9090 * doc.c (Fsubstitute_command_keys): Revert last change.
9092 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9094 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9095 quotes the next character, and doesn't affect other longer
9096 sequences (bug#8935).
9098 * lread.c (syms_of_lread): Clarify that is isn't only
9099 `eval-buffer' and `eval-defun' that's affected by
9100 `lexical-binding' (bug#8460).
9102 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9104 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9105 bidi redisplay when a line includes both an image and is truncated.
9107 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9109 Fix minor problems found by static checking.
9110 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9111 (elsz): Now a signed constant, not a size_t var. We prefer signed
9112 types to unsigned, to avoid integer comparison confusion. Without
9113 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9114 "cannot optimize loop, the loop counter may overflow", a symptom
9116 * indent.c (Fvertical_motion): Mark locals as initialized.
9117 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9119 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9121 * search.c (Fre_search_backward): Mention `case-fold-search' in
9122 all the re_search_* functions (bug#8138).
9124 * keyboard.c (Fopen_dribble_file): Document when the file is
9127 2011-07-14 Eli Zaretskii <eliz@gnu.org>
9129 * bidi.c (bidi_dump_cached_states): Fix format of displaying
9132 Support bidi reordering of display and overlay strings.
9133 * xdisp.c (compute_display_string_pos)
9134 (compute_display_string_end): Accept additional argument STRING.
9135 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9136 (reseat_to_string): Initialize bidi_it->string.s and
9137 bidi_it->string.schars.
9138 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9139 NULL (avoids a crash in bidi_paragraph_init).
9140 Initialize itb.string.lstring.

9641 (clone_per_buffer_values): Don't assume that

9680 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
9682 Random fixes. E.g., (random) never returned negative values.
9683 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9684 subseconds part to the entropy, as that's a bit more random.
9685 Prefer signed to unsigned, since the signedness doesn't matter and
9686 in general we prefer signed. When given a limit, use a
9687 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9688 latter isn't right if USE_2_TAGS_FOR_INTS.
9689 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9690 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9702 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9703 This is more efficient than Ffile_directory_p and avoids a minor race.
9705 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9707 * buffer.c (Foverlay_put): Say what the return value is
9710 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9711 is a directory before asking whether to use the file name
9713 (barf_or_query_if_file_exists): Make the "File is a directory"
9714 error be more correct.
9716 * fns.c (Frequire): Remove the mention of the .gz files, since
9717 that's installation-specific, but keep the mention of
9718 `get-load-suffixes'.
9720 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9722 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9733 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9734 Also (re)move comments that are misplaced or no longer relevant.

9835 * eval.c (struct backtrace): Simplify and port the data structure.
9836 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9837 signed bit field, as this assumption is not portable and it makes
9838 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9839 "char debug_on_exit : 1" as this is not portable either; instead,
9840 use the portable "unsigned int debug_on_exit : 1". Remove unused
9841 member evalargs. Remove obsolete comments about cc bombing out.

10054 Move to minibuffer.el.
10056 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10058 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10059 The following patches are for when GLYPH_DEBUG && !XASSERT.
10060 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10061 * dispnew.c (flush_stdout):
10062 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10063 Mark as externally visible.
10064 * dispnew.c (check_window_matrix_pointers): Now static.
10065 * dispnew.c (window_to_frame_vpos):
10066 * xfns.c (unwind_create_frame):
10067 * xterm.c (x_check_font): Remove unused local.
10068 * scroll.c (CHECK_BOUNDS):
10069 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10070 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10071 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10072 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10073 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10075 (debug_method_add): Use va_list and vsprintf rather than relying
10076 on undefined behavior with wrong number of arguments.
10077 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10078 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10079 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10080 since we're not interested in debugging glyphs with old libraries.
10081 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10082 GCC 4.6.0's static checking.
10084 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10086 Integer overflow and signedness fixes (Bug#8873).

10095 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10096 (x_create_bitmap_from_xpm_data):
10097 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10098 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10100 * xfaces.c (load_pixmap):
10101 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10102 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10103 (.bitmaps_last, struct x_output.icon_bitmap):
10104 Use ptrdiff_t, not int, for bitmap indexes.
10105 (x_allocate_bitmap_record): Check for size overflow.
10106 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10108 Use ptrdiff_t, not int, for overlay counts.
10109 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10110 * editfns.c (overlays_around, get_pos_property):
10111 * textprop.c (get_char_property_and_overlay):
10112 * xdisp.c (next_overlay_change, note_mouse_highlight):
10113 * xfaces.c (face_at_buffer_position):
10114 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10115 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10116 (Fnext_overlay_change, Fprevious_overlay_change)
10117 (mouse_face_overlay_overlaps, Foverlays_in):
10118 Use ptrdiff_t, not int, for sizes.
10119 (overlays_at, overlays_in): Check for size-calculation overflow.
10121 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10123 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10124 (x_session_initialize): Do not assume string length fits in int.
10126 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10127 This is unlikely, but can occur if DPI is outlandish.
10129 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10130 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10132 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10133 * xrdb.c (magic_file_p, search_magic_path):
10134 Omit last arg SUFFIX; it was always 0. All callers changed.
10135 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10137 * xfont.c (xfont_match): Avoid need for strlen.
10139 * xfns.c: Don't assume strlen fits in int.
10140 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10142 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10143 not unsigned long, as we prefer signed integers. All callers changed.
10144 Detect integer overflow in repeat count.
10145 (message_dolog): Don't assume print length fits in 39 bytes.
10146 (display_mode_element): Don't assume strlen fits in int.
10148 * termcap.c: Don't assume sizes fit in int and never overflow.
10149 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10150 (gobble_line): Check for size-calculation overflow.
10152 * minibuf.c (Fread_buffer):
10153 * lread.c (intern, intern_c_string):
10154 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10155 Don't assume string length fits in int.
10157 * keyboard.c (parse_tool_bar_item):
10158 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10160 * font.c: Don't assume string length fits in int.
10161 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10162 Use ptrdiff_t, not int.
10163 (font_intern_prop): Don't assume string length fits in int.
10164 Don't assume integer property fits in fixnum.
10165 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10167 * filelock.c: Fix some buffer overrun and integer overflow issues.
10168 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10169 Reformulate so as not to need the command string.
10170 Invoke gzip -cd rather than gunzip, as it's more portable.
10171 (lock_info_type, lock_file_1, lock_file):
10172 Don't assume pid_t and time_t fit in unsigned long.
10173 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10174 (current_lock_owner): Prefer signed type for sizes.
10175 Use memcpy, not strncpy, where memcpy is what is really wanted.
10176 Don't assume (via atoi) that time_t and pid_t fit in int.
10177 Check for time_t and/or pid_t out of range, e.g., via a network share.
10178 Don't alloca where an auto var works fine.
10180 * fileio.c: Fix some integer overflow issues.
10181 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10182 Don't assume string length fits in int.
10183 (directory_file_name): Don't assume string length fits in long.
10184 (make_temp_name): Don't assume pid fits in int, or that its print
10185 length is less than 20.
10187 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10189 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10191 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10193 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10194 We prefer signed integers, even for size calculations.
10196 * emacs.c: Don't assume string length fits in 'int'.
10197 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10198 (main): Don't invoke strlen when not needed.
10200 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10201 (XD_DEBUG_MESSAGE): Don't waste a byte.
10203 * callproc.c (getenv_internal_1, getenv_internal)
10204 (Fgetenv_internal):
10205 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10207 * lread.c (invalid_syntax): Omit length argument.
10208 All uses changed. This doesn't fix a bug, but it simplifies the
10209 code away from its former Hollerith-constant appearance, and it's
10210 one less 'int' to worry about when looking at integer-overflow issues.
10211 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10213 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10214 This didn't break anything, but it didn't help either.
10215 It's confusing to put a bogus integer in a place where the actual
10216 value does not matter.
10217 (LIST_END_P): Remove unused macro and its bogus comment.
10218 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10220 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10221 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10223 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10224 We prefer signed types, and the value cannot exceed the EMACS_INT
10225 range anyway (because otherwise the length would not be representable).
10226 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10227 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10228 This avoids a GCC warning when WIDE_EMACS_INT.
10230 * indent.c (sane_tab_width): New function.
10231 (current_column, scan_for_column, Findent_to, position_indentation)
10232 (compute_motion): Use it. This is just for clarity.
10233 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10235 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10237 * lisp.h (lint_assume): New macro.
10238 * composite.c (composition_gstring_put_cache):
10239 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10241 * editfns.c, insdel.c:
10242 Omit unnecessary forward decls, to simplify future changes.
10244 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10246 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10248 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10249 Use much-faster test for byte-length change.
10250 Don't assume string byte-length fits in 'int'.
10251 Check that character arg fits in 'int'.
10252 (mapcar1): Declare byte as byte, for clarity.
10254 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10256 * fns.c (concat): Catch string overflow earlier.
10257 Do not rely on integer wraparound.
10259 * dispextern.h (struct it.overlay_strings_charpos)
10260 (struct it.selective): Now EMACS_INT, not int.
10261 * xdisp.c (forward_to_next_line_start)
10262 (back_to_previous_visible_line_start)
10263 (reseat_at_next_visible_line_start, next_element_from_buffer):
10264 Don't arbitrarily truncate the value of 'selective' to int.
10266 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10268 * composite.c: Don't truncate sizes to 'int'.
10269 (composition_gstring_p, composition_reseat_it)
10270 (composition_adjust_point): Use EMACS_INT, not int.
10271 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10272 not EMACS_UINT, for indexes.
10274 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10276 * buffer.c: Include <verify.h>.
10277 (struct sortvec.priority, struct sortstr.priority):
10278 Now EMACS_INT, not int.
10279 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10280 (struct sortstr.size, record_overlay_string)
10281 (struct sortstrlist.size, struct sortlist.used):
10282 Don't truncate size to int.
10283 (record_overlay_string): Check for size-calculation overflow.
10284 (init_buffer_once): Check at compile-time, not run-time.
10286 2011-06-22 Jim Meyering <meyering@redhat.com>
10288 Don't leak an XBM-image-sized buffer
10289 * image.c (xbm_load): Free the image buffer after using it.
10291 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10294 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10295 that Sun C diagnosed.
10296 * fns.c (secure_hash): Fix pointer signedness issue.
10297 * intervals.c (static_offset_intervals): New function.
10298 (offset_intervals): Use it.
10300 2011-06-21 Leo Liu <sdl.web@gmail.com>
10303 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10306 * fns.c (secure_hash): Rename from crypto_hash_function and change
10307 the first arg to accept symbols.
10308 (Fsecure_hash): New primitive.
10309 (syms_of_fns): New symbols.
10311 2011-06-20 Deniz Dogan <deniz@dogan.se>
10313 * process.c (Fset_process_buffer): Clarify return value in
10316 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10318 * dispnew.c (add_window_display_history): Use BVAR.
10320 * xdisp.c (debug_method_add): Use BVAR.
10321 (check_window_end, dump_glyph_matrix, dump_glyph)
10322 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10324 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10327 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10328 check till after the cache is created in init_frame_faces.
10330 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10332 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10334 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10336 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10337 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10338 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10340 Improve buffer-overflow checking (Bug#8873).
10341 * fileio.c (Finsert_file_contents):
10342 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10343 Remove the old (too-loose) buffer overflow checks.
10344 They weren't needed, since make_gap checks for buffer overflow.
10345 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10346 The old code merely checked for Emacs fixnum overflow, and relied
10347 on undefined (wraparound) behavior. The new code avoids undefined
10348 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10350 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10351 Tune. Don't use wider integers than needed. Don't use alloca.
10352 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10354 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10356 * insdel.c, lisp.h (buffer_overflow): New function.
10357 (insert_from_buffer_1, replace_range, replace_range_2):
10358 * insdel.c (make_gap_larger):
10359 * editfns.c (Finsert_char):
10360 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10362 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10364 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10366 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10368 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10369 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10371 * fileio.c: Don't assume EMACS_INT fits in off_t.
10372 (emacs_lseek): New static function.
10373 (Finsert_file_contents, Fwrite_region): Use it.
10374 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10376 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10378 * fns.c: Don't overflow int when computing a list length.
10379 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10380 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10381 truncation on 64-bit hosts. Check for QUIT every
10382 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10383 faster and is responsive enough.
10384 (Flength): Report an error instead of overflowing an integer.
10385 (Fsafe_length): Return a float if the value is not representable
10386 as a fixnum. This shouldn't happen except in contrived situations.
10387 (Fnthcdr, Fsort): Don't assume list length fits in int.
10388 (Fcopy_sequence): Don't assume vector length fits in int.
10390 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10391 (header_size, word_size): New constants.
10392 (allocate_vectorlike): Don't check size overflow here.
10393 (allocate_vector): Check it here instead, since this is the only
10394 caller of allocate_vectorlike that could cause overflow.
10395 Check that the new vector's length is representable as a fixnum.
10397 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10398 The previous code was bogus. For example, next_almost_prime (32)
10399 returned 39, which is undesirable as it is a multiple of 3; and
10400 next_almost_prime (24) returned 25, which is a multiple of 5 so
10401 why was the code bothering to check for multiples of 7?
10403 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10405 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10407 Variadic C functions now count arguments with ptrdiff_t.
10408 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10409 Back then I didn't know that the Emacs coding style prefers signed int.
10410 Also, in the meantime I found a few more instances where arguments
10411 were being counted with int, which may truncate counts on 64-bit
10412 machines, or EMACS_INT, which may be unnecessarily wide.
10413 * lisp.h (struct Lisp_Subr.function.aMANY)
10414 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10415 Arg counts are now ptrdiff_t, not size_t.
10416 All variadic functions and their callers changed accordingly.
10417 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10418 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10419 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10420 * callint.c (Fcall_interactively): Check arg count for overflow,
10421 to avoid potential buffer overrun. Use signed char, not 'int',
10422 for 'varies' array, so that we needn't bother to check its size
10423 calculation for overflow.
10424 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10425 * eval.c (apply_lambda):
10426 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10427 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10428 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10430 * callint.c (Fcall_interactively): Don't use index var as event count.
10432 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10433 * mem-limits.h (SIZE): Remove; no longer used.
10435 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10437 Remove unnecessary casts.
10438 * xterm.c (x_term_init):
10439 * xfns.c (x_set_border_pixel):
10440 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10441 These aren't needed now that we assume ANSI C.
10443 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10444 It's more likely to cause problems (due to unsigned overflow)
10447 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10449 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10451 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10453 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10455 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10457 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10459 GLYPH_CODE_FACE returns EMACS_INT, not int.
10460 * dispextern.h (merge_faces):
10461 * xfaces.c (merge_faces):
10462 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10463 Don't assume EMACS_INT fits in int.
10465 * character.h (CHAR_VALID_P): Remove unused parameter.
10466 * fontset.c, lisp.h, xdisp.c: All uses changed.
10468 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10470 * fns.c (concat): Minor tuning based on overflow analysis.
10471 This doesn't fix any bugs. Use int to hold character, instead
10472 of constantly refetching from Emacs object. Use XFASTINT, not
10473 XINT, for value known to be a character. Don't bother comparing
10474 a single byte to 0400, as it's always less.
10476 * floatfns.c (Fexpt):
10477 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10479 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10482 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10484 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10485 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10486 incorrectly succeed when S was a string, because 4294967386 was
10487 truncated before it was used.
10489 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10490 Otherwise, an out-of-range integer could cause undefined behavior
10493 * composite.c: Use int, not EMACS_INT, for characters.
10494 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10495 EMACS_INT, for values that are known to be in character range.
10496 This doesn't fix any bugs but is the usual style inside Emacs and
10497 may generate better code on 32-bit machines.
10499 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10500 This is for reasons similar to the recent CHAR_STRING fix.
10501 * charset.c (Fencode_char): Check that character arg is actually
10502 a character. Pass an int to ENCODE_CHAR.
10503 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10504 wider than 'int', as a compile-time check to prevent future regressions
10507 * character.c (char_string): Remove unnecessary casts.
10509 Make sure a 64-bit char is never passed to CHAR_STRING.
10510 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10511 by silently ignoring the top 32 bits, allowing some values
10512 that were far too large to be valid characters.
10513 * character.h: Include <verify.h>.
10514 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10515 arguments are no wider than unsigned, as a compile-time check
10516 to prevent future regressions in this area.
10518 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10519 (Fsubst_char_in_region):
10521 * xdisp.c (decode_mode_spec_coding):
10522 Adjust to CHAR_STRING's new requirement.
10523 * editfns.c (Finsert_char, Fsubst_char_in_region):
10524 * fns.c (concat): Check that character args are actually
10525 characters. Without this test, these functions did the wrong
10526 thing with wildly out-of-range values on 64-bit hosts.
10528 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10529 These casts should not be needed on 32-bit hosts, either.
10530 * keyboard.c (read_char):
10531 * lread.c (Fload): Remove casts to unsigned.
10533 * lisp.h (UNSIGNED_CMP): New macro.
10534 This fixes comparison bugs on 64-bit hosts.
10535 (ASCII_CHAR_P): Use it.
10536 * casefiddle.c (casify_object):
10537 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10538 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10539 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10540 * dispextern.h (FACE_FROM_ID):
10541 * keyboard.c (read_char): Use UNSIGNED_CMP.
10543 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10544 not to EMACS_INT, to avoid GCC warning.
10546 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10548 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10549 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10550 isn't needed on 32-bit machines.
10552 * buffer.c (Fgenerate_new_buffer_name):
10553 Use EMACS_INT for count, not int.
10554 (advance_to_char_boundary): Return EMACS_INT, not int.
10556 * data.c (Qcompiled_function): Now static.
10558 * window.c (window_body_lines): Now static.
10560 * image.c (gif_load): Rename local to avoid shadowing.
10562 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10563 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10564 * alloc.c (make_save_value): Integer argument is now of type
10565 ptrdiff_t, not int.
10566 (mark_object): Use ptrdiff_t, not int.
10567 * lisp.h (pD): New macro.
10568 * print.c (print_object): Use it.
10570 * alloc.c: Use EMACS_INT, not int, to count objects.
10571 (total_conses, total_markers, total_symbols, total_vector_size)
10572 (total_free_conses, total_free_markers, total_free_symbols)
10573 (total_free_floats, total_floats, total_free_intervals)
10574 (total_intervals, total_strings, total_free_strings):
10575 Now EMACS_INT, not int. All uses changed.
10576 (Fgarbage_collect): Compute overall total using a double, so that
10577 integer overflow is less likely to be a problem. Check for overflow
10578 when converting back to an integer.
10579 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10580 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10581 These were 'int' variables that could overflow on 64-bit hosts;
10582 they were never used, so remove them instead of repairing them.
10583 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10584 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10585 Previously, this ceilinged at INT_MAX, but that doesn't work on
10587 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10589 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10590 (allocate_vectorlike): Check for ptrdiff_t overflow.
10591 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10592 when a (possibly-narrower) signed value would do just as well.
10593 We prefer using signed arithmetic, to avoid comparison confusion.
10595 * alloc.c: Catch some string size overflows that we were missing.
10596 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10597 for convenience in STRING_BYTES_MAX.
10598 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10599 The definition here is exact; the one in lisp.h was approximate.
10600 (allocate_string_data): Check for string overflow. This catches
10601 some instances we weren't catching before. Also, it catches
10602 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10603 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10604 and ptrdiff_t and EMACS_INT are both 64 bits.
10606 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10607 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10608 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10610 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10612 * alloc.c (Fmake_string): Check for out-of-range init.
10614 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10616 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10618 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10620 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

10623 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10624 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10625 (style_changed_cb): Call update_theme_scrollbar_width and call
10626 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10627 all frames (Bug#8505).
10628 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10629 Call gtk_window_set_resizable if HAVE_GTK3.
10630 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10631 and height if HAVE_GTK3 (Bug#8505).
10632 (scroll_bar_width_for_theme): New variable.
10633 (update_theme_scrollbar_width): New function.
10634 (xg_get_default_scrollbar_width): Move code to
10635 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10636 (xg_initialize): Call update_theme_scrollbar_width.
10638 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10640 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10642 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10644 * frame.c (make_frame): Call other_buffer_safely instead of
10647 * window.c (temp_output_buffer_show): Call display_buffer with
10648 second argument Vtemp_buffer_show_specifiers and reset latter
10649 immediately after the call.
10650 (Vtemp_buffer_show_specifiers): New variable.
10651 (auto_window_vscroll_p, next_screen_context_lines)
10652 (Vscroll_preserve_screen_position): Remove leading asterisks from

11216 value of a `display' property is a "replacing spec".
11217 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11218 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11248 * gnutls.c: Use Emacs's memory allocators.
11249 Without this change, the gnutls library would invoke malloc etc.
11250 directly, which causes problems on non-SYNC_INPUT hosts, and which
11251 runs afoul of improving memory_full behavior. (Bug#8761)
11252 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11253 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11254 xfree instead of the default malloc, realloc, free.
11255 (Fgnutls_boot): No need to check for memory allocation failure,
11256 since xmalloc does that for us.

11285 need to be updated by these changes.
11286 * fns.c (make_hash_table, maybe_resize_hash_table):
11287 Check for integer overflow with large hash tables.
11288 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11289 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11290 (SXHASH_REDUCE): New macro.
11291 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11292 Use it instead of discarding useful hash info with large hash values.

11294 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11295 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11296 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11297 Rewrite to use FIXNUM_BITS, as this simplifies things.
11298 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11299 Adjust signatures to match updated version of code.
11300 (consing_since_gc): Now EMACS_INT, since a single hash table can
11301 use more than INT_MAX bytes.

11350 Make it possible to run ./temacs.
11352 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11353 syms_of_callproc does the same thing. Remove test for
11354 "initialized", do it in the caller.
11355 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11357 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11359 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11360 (read_minibuf): Use get_minibuffer.
11361 (syms_of_minibuf): Use DEFSYM.
11362 (Qmetadata): New var.
11363 * data.c (Qbuffer): Don't make it static.
11364 (syms_of_data): Use DEFSYM.
11366 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11368 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11369 (CCL_CODE_MIN): New macro.
11371 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11373 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11375 * eval.c (Qdebug): Now static.
11376 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11377 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11378 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11380 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11382 * image.c: Various fixes to ImageMagick code comments.
11383 (Fimagemagick_types): Doc fix.
11385 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11387 Minor fixes prompted by GCC 4.6.0 warnings.
11389 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11391 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11392 (x_clipboard_manager_save_all): Move extern decl to ...
11393 * xterm.h: ... here, so that it can be checked for consistency.
11395 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11397 * xselect.c (x_clipboard_manager_save_frame)
11398 (x_clipboard_manager_save_all): New functions.
11399 (Fx_clipboard_manager_save): Lisp function deleted.
11401 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11402 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11404 * xterm.h: Update prototype.
11406 2011-05-28 William Xu <william.xwl@gmail.com>
11408 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11409 exiting (Bug#8239).
11411 2011-05-28 Jim Meyering <meyering@redhat.com>
11413 Avoid a sign-extension bug in crypto_hash_function.
11414 * fns.c (to_uchar): Define.
11415 (crypto_hash_function): Use it to convert some newly-signed
11416 variables to unsigned, to avoid sign-extension bugs. For example,
11417 without this change, (md5 "truc") would evaluate to
11418 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11419 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11420 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11422 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11424 Integer overflow fixes.
11426 * dbusbind.c: Serial number integer overflow fixes.
11427 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11428 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11429 to hold a serial number that is too large for a fixnum.
11430 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11431 Check for serial numbers out of range. Decode any serial number
11432 that was so large that it became a float. (Bug#8722)
11434 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11435 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11436 Use XFASTINT rather than XUINT when numbers are nonnegative.
11437 (xd_append_arg, Fdbus_method_return_internal):
11438 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11439 arguments, check that Lisp number is nonnegative, rather than
11440 silently wrapping negative numbers around. (Bug#8722)
11441 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11444 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11446 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11448 ccl: Add integer overflow checks.
11449 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11450 (IN_INT_RANGE): New macros.
11451 (ccl_driver): Use them to check for integer overflow when
11452 decoding a CCL program. Many of the new checks are whether XINT (x)
11453 fits in int; it doesn't always, on 64-bit hosts. The new version
11454 doesn't catch all possible integer overflows, but it's an
11455 improvement. (Bug#8719)
11457 * alloc.c (make_event_array): Use XINT, not XUINT.
11458 There's no need for unsigned here.
11460 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11461 This follows up to the 2011-05-06 change that substituted uintptr_t
11462 for EMACS_INT. This case wasn't caught back then.
11464 Rework Fformat to avoid integer overflow issues.
11465 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11466 now (part of C89). Include <verify.h>.
11467 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11468 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11469 (Fformat): Avoid the prepass trying to compute sizes; it was only
11470 approximate and thus did not catch overflow reliably. Instead, walk
11471 through the format just once, formatting and computing sizes as we go,
11472 checking for integer overflow at every step, and allocating a larger
11473 buffer as needed. Keep track separately whether the format is
11474 multibyte. Keep only the most-recently calculated precision, rather
11475 than them all. Record whether each argument has been converted to
11476 string. Use EMACS_INT, not int, for byte and char and arg counts.
11477 Support field widths and precisions larger than INT_MAX. Avoid
11478 sprintf's undefined behavior with conversion specifications such as %#d
11479 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11480 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11481 formatting out-of-range floating point numbers with int
11482 formats. (Bug#8668)
11484 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11486 * data.c: Avoid integer truncation in expressions involving floats.
11487 * data.c: Include <intprops.h>.
11488 (arith_driver): When there's an integer overflow in an expression
11489 involving floating point, convert the integers to floating point
11490 so that the resulting value does not suffer from catastrophic
11491 integer truncation. For example, on a 64-bit host (* 4
11492 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11493 Do not rely on undefined behavior after integer overflow.
11495 merge count_size_as_multibyte, parse_str_to_multibyte
11496 * character.c, character.h (count_size_as_multibyte):
11497 Rename from parse_str_to_multibyte; all uses changed.
11498 Check for integer overflow.
11499 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11500 since it's now a duplicate of the other. This is more of
11501 a character than a buffer op, so better that it's in character.c.
11502 * fns.c, print.c: Adjust to above changes.
11504 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11506 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11508 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11510 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11511 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11512 (x_clipboard_manager_save): Now static.
11513 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11515 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11516 (crypto_hash_function): Now static.
11517 Fix pointer signedness problems. Avoid unnecessary initializations.
11519 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11521 * termhooks.h (Vselection_alist): Make it terminal-local.
11523 * terminal.c (create_terminal): Initialize it.
11525 * xselect.c: Support for clipboard managers.
11526 (Vselection_alist): Move to termhooks.h as terminal-local var.
11527 (LOCAL_SELECTION): New macro.
11528 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11529 (symbol_to_x_atom): Remove gratuitous arg.
11530 (x_handle_selection_request, lisp_data_to_selection_data)
11531 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11532 (x_own_selection, x_get_local_selection, x_convert_selection):
11533 New arg, specifying work frame. Use terminal-local Vselection_alist.
11534 (some_frame_on_display): Delete unused function.
11535 (Fx_own_selection_internal, Fx_get_selection_internal)
11536 (Fx_disown_selection_internal, Fx_selection_owner_p)
11537 (Fx_selection_exists_p): New optional frame arg.
11538 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11539 (x_handle_selection_clear): Don't treat other terminals with the
11540 same keyboard specially. Use the terminal-local Vselection_alist.
11541 (x_clear_frame_selections): Use Frun_hook_with_args.
11543 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11545 * xterm.h: Add support for those atoms.
11547 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11549 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11550 (converted_selections, conversion_fail_tag): New global variables.
11551 (x_selection_request_lisp_error): Free the above.
11552 (x_get_local_selection): Remove unnecessary code.
11553 (x_reply_selection_request): Args changed; handle arbitrary array
11554 of converted selections stored in converted_selections.
11555 Separate the XChangeProperty and SelectionNotify steps.
11556 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11557 (x_convert_selection): New function.
11558 (x_handle_selection_event): Simplify.
11559 (x_get_foreign_selection): Don't ignore incoming requests while
11560 waiting for an answer; this will fail when we implement
11561 SAVE_TARGETS, and seems unnecessary anyway.
11562 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11563 (Vx_sent_selection_functions): Doc fix.
11565 2011-05-26 Leo Liu <sdl.web@gmail.com>
11567 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11569 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11571 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11573 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11574 for fringe update if it has periodic bitmap.
11575 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11576 and fringe_bitmap_periodic_p.
11578 * fringe.c (get_fringe_bitmap_data): New function.
11579 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11580 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11581 row. Mark glyph row for fringe update if periodicity changed.
11583 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11584 for fringe update unless it has periodic bitmap.
11586 2011-05-25 Kenichi Handa <handa@m17n.org>
11588 * xdisp.c (get_next_display_element): Set correct it->face_id for
11589 a static composition.
11591 2011-05-24 Leo Liu <sdl.web@gmail.com>
11594 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11596 * fns.c (crypto_hash_function, Fsha1): New function.
11597 (Fmd5): Use crypto_hash_function.
11598 (syms_of_fns): Add Ssha1.
11600 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11602 * gnutls.c: Remove unused macros.
11603 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11604 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11605 Remove macros that are defined and never used.
11606 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11608 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11610 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11611 (Fx_get_selection_internal): Minor cleanup.
11612 (Fx_own_selection_internal): Rename arguments for consistency with
11615 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11617 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11619 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11621 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11623 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11625 * dispnew.c (scrolling_window): Don't exclude the case that the
11626 last enabled row in the desired matrix touches the bottom boundary.
11628 2011-05-21 Glenn Morris <rgm@gnu.org>
11630 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11631 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11632 and add some more files.
11634 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11636 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11637 report_file_error introduced by the change from 2011-05-07.
11639 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11641 * systime.h (Time): Define only if emacs is defined.
11642 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11643 where the include path doesn't have X11/X.h by default. See
11644 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11646 2011-05-20 Kenichi Handa <handa@m17n.org>
11648 * composite.c (find_automatic_composition): Fix previous change.
11650 2011-05-20 Glenn Morris <rgm@gnu.org>
11652 * lisp.mk: New file, split from Makefile.in.
11653 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11654 (shortlisp): Remove.
11655 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11657 2011-05-19 Glenn Morris <rgm@gnu.org>
11659 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11660 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11661 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11662 (lisp): Set the order to that of loadup.el.
11663 (shortlisp): Make it a copy of $lisp.
11664 (SOME_MACHINE_LISP): Remove.
11665 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11666 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11668 2011-05-18 Kenichi Handa <handa@m17n.org>
11670 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11671 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11672 (find_automatic_composition): Mostly rewrite for efficiency.
11674 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11676 * makefile.w32-in: Update dependencies.
11678 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11680 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11681 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11683 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11685 Fix some integer overflow issues, such as string length overflow.
11687 * insdel.c (count_size_as_multibyte): Check for string overflow.
11689 * character.c (lisp_string_width): Check for string overflow.
11690 Use EMACS_INT, not int, for string indexes and lengths; in
11691 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11692 the resulting string length overflows an EMACS_INT; instead,
11693 report a string overflow if no precision given. When checking for
11694 precision exhaustion, use a check that cannot possibly have
11695 integer overflow. (Bug#8675)
11696 * character.h (lisp_string_width): Adjust to new signature.
11698 * alloc.c (string_overflow): New function.
11699 (Fmake_string): Use it. This doesn't change behavior, but saves
11700 a few bytes and will simplify future changes.
11701 * character.c (string_escape_byte8): Likewise.
11702 * lisp.h (string_overflow): New decl.
11704 Fixups, following up to the user-interface timestamp change.
11705 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11706 for UI timestamps, instead of unsigned long.
11707 * msdos.c (mouse_get_pos): Likewise.
11708 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11709 * w32gui.h (Time): Define by including "systime.h" rather than by
11710 declaring it ourselves. (Bug#8664)
11712 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11713 * image.c (clear_image_cache): Likewise.
11715 * term.c (term_mouse_position): Don't assume time_t wraparound.
11717 Be more systematic about user-interface timestamps.
11718 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11719 and sometimes 'EMACS_UINT', to represent these timestamps.
11720 This change causes it to use 'Time' uniformly, as that's what X uses.
11721 This makes the code easier to follow, and makes it easier to catch
11722 integer overflow bugs such as Bug#8664.
11723 * frame.c (Fmouse_position, Fmouse_pixel_position):
11724 Use Time, not unsigned long, for user-interface timestamps.
11725 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11726 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11727 * keyboard.h (last_event_timestamp): Likewise.
11728 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11729 * menu.h (xmenu_show): Likewise.
11730 * term.c (term_mouse_position): Likewise.
11731 * termhooks.h (struct input_event.timestamp): Likewise.
11732 (struct terminal.mouse_position_hook): Likewise.
11733 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11734 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11735 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11736 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11737 what it was before.
11738 * menu.h, termhooks.h: Include "systime.h", for Time.
11740 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11741 Don't assume that the difference between two unsigned long values
11742 can fit into an integer. At this point, we know button_down_time
11743 <= event->timestamp, so the difference must be nonnegative, so
11744 there's no need to cast the result if double-click-time is
11745 nonnegative, as it should be; check that it's nonnegative, just in
11746 case. This bug is triggered when events are more than 2**31 ms
11747 apart (about 25 days). (Bug#8664)
11749 * xselect.c (last_event_timestamp): Remove duplicate decl.
11750 (x_own_selection): Remove needless cast to unsigned long.
11752 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11753 that always fit in int. Use a sentinel instead of a counter, to
11754 avoid a temp and to allay GCC's concerns about possible int overflow.
11755 * frame.h (struct frame): Use int for menu_bar_items_used
11756 instead of EMACS_INT, since it always fits in int.
11758 * menu.c (grow_menu_items): Check for int overflow.
11760 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11762 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11763 Before, the code was not consistent. These values cannot exceed
11764 2**31 - 1 so there's no need to make them unsigned.
11765 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11766 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11767 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11769 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11771 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11772 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11773 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11774 presumably because the widths might not match.
11776 * window.c (size_window): Avoid needless test at loop start.
11778 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11780 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11782 2011-05-12 Drew Adams <drew.adams@oracle.com>
11784 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11786 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11788 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11789 `width' to `bar_area_x' and `bar_area_width', respectively.
11790 (x_scroll_run): Take account of fringe background extension.
11792 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11793 Rename local vars `left' and `width' to `bar_area_x' and
11794 `bar_area_width', respectively.
11795 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11796 background extension.
11798 2011-05-10 Jim Meyering <meyering@redhat.com>
11800 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11802 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11804 * image.c (Finit_image_library): Return t for built-in image types,
11805 like pbm and xbm. (Bug#8640)
11807 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11809 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11811 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11813 * w32console.c (Fset_screen_color): Doc fix.
11814 (Fget_screen_color): New function.
11815 (syms_of_ntterm): Defsubr it.
11817 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11818 unlink the temporary file if Fcall_process didn't create it in the
11820 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11821 child process will be redirected to a file specified with `:file'.
11822 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11823 cue to call_process_cleanup not to close that handle.
11825 2011-05-07 Ben Key <bkey76@gmail.com>
11827 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11828 one of two shell specific rules, either bootstrap-temacs-CMD or
11829 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11830 to the previous implementation of the bootstrap-temacs rule.
11831 The bootstrap-temacs-CMD rule is similar to the previous
11832 implementation of the bootstrap-temacs rule except that it
11833 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11836 These changes, along with some changes to nt/configure.bat,
11837 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11838 earlier fix to add support for --cflags and --ldflags options
11839 that include quotes so that it works whether make uses cmd or
11842 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11844 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11845 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11847 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11848 a string. Handle both cases.
11849 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11850 (Fdbus_register_method): Use Qinvalid_function.
11852 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11854 * makefile.w32-in: Update dependencies.
11855 (LISP_H): Add inttypes.h and stdin.h.
11856 (PROCESS_H): Add unistd.h.
11858 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11860 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11861 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11863 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11865 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11867 * term.c (vfatal): Remove stray call to va_end.
11868 It's not needed and the C Standard doesn't allow it here anyway.
11870 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11871 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11873 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11876 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11878 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11880 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11882 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11884 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11886 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11887 * charset.c (Fdefine_charset_internal): Don't initialize
11888 charset.code_space[15]. The value was garbage, on hosts with
11889 32-bit int (Bug#8600).
11891 * lread.c (read_integer): Be more consistent with string-to-number.
11892 Use string_to_number to do the actual conversion; this avoids
11893 rounding errors and fixes some other screwups. Without this fix,
11894 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11895 (digit_to_number): Move earlier, for benefit of read_integer.
11896 Return -1 if the digit is out of range for the base, -2 if it is
11897 not a digit in any supported base. (Bug#8602)
11899 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11901 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11902 to match comment at start of function. This also removes a
11903 GCC warning about overflow in a 32+64-bit port.
11905 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11907 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11908 Reported by Stefan Monnier in
11909 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11910 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11911 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11913 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11914 (EMACS_UINTPTR): Likewise, with uintptr_t.
11916 * lisp.h: Prefer 64-bit EMACS_INT if available.
11917 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11918 on 32-bit hosts that have 64-bit int, so that they can access
11920 However, temporarily disable this change unless the temporary
11921 symbol WIDE_EMACS_INT is defined.
11923 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11925 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11926 This removes an assumption that EMACS_INT and long are the same
11927 width as pointers. The assumption is true for Emacs porting targets
11928 now, but we want to make other targets possible.
11929 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11930 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11931 In the rest of the code, change types of integers that hold casted
11932 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11933 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11934 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11935 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11936 No need to cast type when ORing.
11937 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11938 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11939 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11940 assume EMACS_INT is the same width as char *.
11941 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11942 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11943 Remove no-longer-needed casts.
11944 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11945 (xg_tool_bar_help_callback, xg_make_tool_item):
11946 Use EMACS_INTPTR to hold an integer
11947 that will be cast to void *; this can avoid a GCC warning
11948 if EMACS_INT is not the same width as void *.
11949 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11950 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11951 (current_message_1, set_message_1):
11952 Use a local to convert to proper width without a cast.
11953 * xmenu.c (dialog_selection_callback): Likewise.
11955 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11956 Also, don't assume VALBITS / RAND_BITS is less than 5,
11957 and don't rely on undefined behavior when shifting a 1 left into
11959 * lisp.h (get_random): Change signature to match.
11961 * lread.c (hash_string): Use size_t, not int, for hash computation.
11962 Normally we prefer signed values; but hashing is special, because
11963 it's better to use unsigned division on hash table sizes so that
11964 the remainder is nonnegative. Also, size_t is the natural width
11965 for hashing into memory. The previous code used 'int', which doesn't
11966 retain enough info to hash well into very large tables.
11967 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11969 * dbusbind.c: Don't possibly lose pointer info when converting.
11970 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11971 Use XPNTR rather than XHASH, so that the high-order bits of
11972 the pointer aren't lost when converting through void *.
11974 * eval.c (Fautoload): Don't double-shift a pointer.
11976 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11978 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11980 * gnutls.c (DEF_GNUTLS_FN):
11981 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11983 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11985 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11988 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11990 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11991 New version that can reserve upto 2GB of heap space.
11993 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11995 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

11999 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12000 `gnutls_certificate_set_x509_key_file'.
12002 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12004 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12005 Update dependencies.
12007 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12009 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12010 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12011 Remove unused parameter `fildes'.
12012 * process.c (read_process_output, send_process): Don't pass it.
12014 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12016 Fix previous change: the library cache is defined in w32.c.
12017 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12018 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12020 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12022 Implement dynamic loading of GnuTLS on Windows.
12024 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12025 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12026 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12029 * gnutls.c (Qgnutls_dll): Define.
12030 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12031 (gnutls_*): Declare function pointers.
12032 (init_gnutls_functions): New function to initialize function pointers.

12035 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12036 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12037 (emacs_gnutls_write, emacs_gnutls_read)
12038 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12039 (Fgnutls_available_p): New function.
12040 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12041 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12042 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12044 * image.c: Include w32.h.
12045 (Vimage_type_cache): Delete.
12046 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12047 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12048 (w32_delayed_load): Move to w32.c.
12050 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12052 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12053 (w32_delayed_load): Move from image.c. When loading a library, record
12054 its filename in the :loaded-from property of the library id.
12055 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12056 Initialize and staticpro them.
12057 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12059 * process.c: Include lisp.h before w32.h, not after.
12060 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12061 instead of gnutls_record_check_pending.
12063 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12065 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12067 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12068 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12071 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12073 * xterm.c (x_set_frame_alpha): Do not set property on anything
12074 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12076 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12078 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12080 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12082 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

12090 (Qgnutls_bootprop_callbacks_verify): Make static.
12092 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12094 * callproc.c: Indentation fixup.
12096 * sysdep.c (wait_for_termination_1): Make static.
12097 (wait_for_termination, interruptible_wait_for_termination):
12098 Move after wait_for_termination_1.
12100 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12102 * sysdep.c (interruptible_wait_for_termination): New function
12103 which is like wait_for_termination, but allows keyboard
12106 * callproc.c (Fcall_process): Add (:file "file") as an option for
12108 (Fcall_process_region): Ditto.
12110 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12112 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12113 rather than `XVECTOR (FOO)->size'.
12115 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12116 inttypes.h, as a gnulib replacement is used if it not available in
12119 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12121 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12122 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12123 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12125 * coding.c (coding_alloc_by_realloc): Error out if destination
12126 will grow beyond MOST_POSITIVE_FIXNUM.
12127 (decode_coding_emacs_mule): Abort if there isn't enough place in
12128 charbuf for the composition carryover bytes. Reserve an extra
12129 space for up to 2 characters produced in a loop.
12130 (decode_coding_iso_2022): Abort if there isn't enough place in
12131 charbuf for the composition carryover bytes.

12136 aborting when %lld or %lll format is passed.
12137 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12138 %llo or %llx format is passed. (Bug#8545)
12140 * window.c (window_scroll_line_based): Use a marker instead of
12141 simple variables to record original value of point. (Bug#7952)
12143 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12144 produced by %s or %c overflows available buffer space. (Bug#8545)
12146 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12148 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12149 (SIZE_MAX): Move defn after all includes, as they might #define it.
12151 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12153 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12155 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12157 * keyboard.c (Qdelayed_warnings_hook): Define.
12158 (command_loop_1): Run `delayed-warnings-hook'
12159 if Vdelayed_warnings_list is non-nil.
12160 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12161 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12163 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12165 * doprnt.c (doprnt): Don't return value smaller than the buffer
12166 size if the message was truncated. (Bug#8545).
12168 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12170 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12171 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12173 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12175 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12177 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12179 * makefile.w32-in: Update dependencies.
12181 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12183 Improve `doprnt' and its usage. (Bug#8545)
12184 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12185 `format_end'. Remove support for %l as a conversion specifier.
12186 Don't use xrealloc. Improve diagnostics when the %l size modifier
12187 is used. Update the commentary.
12189 * eval.c (verror): Simplify calculation of size_t.
12191 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12194 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12196 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12199 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12201 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12202 This makes this file independent of the recent pseudovector change.
12204 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12206 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12208 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12209 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12210 Remove unused local.
12211 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12213 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12214 GCC 4.6.0 optimizes based on type-based alias analysis.
12215 For example, if b is of type struct buffer * and v of type struct
12216 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12217 != &v->size, and therefore "v->size = 1; b->size = 2; return
12218 v->size;" must therefore return 1. This assumption is incorrect
12219 for Emacs, since it type-puns struct Lisp_Vector * with many other
12220 types. To fix this problem, this patch adds a new type struct
12221 vectorlike_header that documents the constraints on layout of vectors
12222 and pseudovectors, and helps optimizing compilers not get fooled
12223 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12224 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12225 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12227 (XSETPVECTYPE): Rewrite in terms of new macro.
12228 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12229 This is a bit clearer, and further avoids the possibility of
12230 undesirable aliasing.
12231 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12232 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12233 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12234 since Lisp_Subr is a special case (no "next" field).
12235 (ASIZE): Now uses header.size rather than size.
12236 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12237 to avoid the hassle of writing XVECTOR (foo)->header.size.
12238 (struct vectorlike_header): New type.
12239 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12240 object, to help avoid aliasing.
12241 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12242 (SUBRP): Likewise, since Lisp_Subr is a special case.
12243 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12244 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12245 (struct Lisp_Hash_Table): Combine first two members into a single
12246 struct vectorlike_header member. All uses of "size" and "next" members
12247 changed to be "header.size" and "header.next".
12248 * buffer.h (struct buffer): Likewise.
12249 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12250 * frame.h (struct frame): Likewise.
12251 * process.h (struct Lisp_Process): Likewise.
12252 * termhooks.h (struct terminal): Likewise.
12253 * window.c (struct save_window_data, struct saved_window): Likewise.
12254 * window.h (struct window): Likewise.
12255 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12256 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12257 * buffer.c (init_buffer_once): Likewise.
12258 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12260 * process.c (Fformat_network_address): Use local var for size,
12263 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12265 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12266 * data.c (atof): Remove decl; no longer used or needed.
12267 (digit_to_number): Move to lread.c.
12268 (Fstring_to_number): Use new string_to_number function, to be
12269 consistent with how the Lisp reader treats infinities and NaNs.
12270 Do not assume that floating-point numbers represent EMACS_INT
12271 without losing information; this is not true on most 64-bit hosts.
12272 Avoid double-rounding errors, by insisting on integers when
12273 parsing non-base-10 numbers, as the documentation specifies.
12274 * lisp.h (string_to_number): New decl, replacing ...
12275 (isfloat_string): Remove.
12276 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12277 (read1): Do not accept +. and -. as integers; this
12278 appears to have been a coding error. Similarly, do not accept
12279 strings like +-1e0 as floating point numbers. Do not report
12280 overflow for integer overflows unless the base is not 10 which
12281 means we have no simple and reliable way to continue.
12282 Break out the floating-point parsing into a new
12283 function string_to_number, so that Fstring_to_number parses
12284 floating point numbers consistently with the Lisp reader.
12285 (digit_to_number): Move here from data.c. Make it static inline.
12286 (E_CHAR, EXP_INT): Remove, replacing with ...
12287 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12288 (string_to_number): New function, replacing isfloat_string.
12289 This function checks for valid syntax and produces the resulting
12290 Lisp float number too. Rework it so that string-to-number
12291 no longer mishandles examples like "1.0e+". Use strtoumax,
12292 so that overflow for non-base-10 numbers is reported only when
12293 there's no portable and simple way to convert to floating point.
12295 * textprop.c (set_text_properties_1): Rewrite for clarity,
12296 and to avoid GCC warning about integer overflow.
12298 * intervals.h (struct interval): Use EMACS_INT for members
12299 where EMACS_UINT might cause problems. See
12300 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12301 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12302 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12304 (offset_intervals): Tell GCC not to worry about length overflow
12305 when negating a negative length.
12307 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12308 (overrun_check_free): Likewise.
12310 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12311 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12314 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12315 (gnutls_make_error): Rename local to avoid shadowing.
12316 (gnutls_emacs_global_deinit): ifdef out; not used.
12317 (Fgnutls_boot): Use const for pointer to readonly storage.
12318 Comment out unused local. Fix pointer signedness problems.
12320 * lread.c (openp): Don't stuff size_t into an 'int'.
12321 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12322 about possible signed overflow.
12324 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12325 (GDK_KEY_g): Don't define if already defined.
12326 (xg_prepare_tooltip): Avoid pointer signedness problem.
12327 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12329 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12330 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12332 * xfns.c (Fx_window_property): Simplify a bit,
12333 to make a bit faster and to avoid GCC 4.6.0 warning.
12334 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12336 * fns.c (internal_equal): Don't assume size_t fits in int.
12338 * alloc.c (compact_small_strings): Tighten assertion a little.
12340 Replace pEd with more-general pI, and fix some printf arg casts.
12341 * lisp.h (pI): New macro, generalizing old pEd macro to other
12342 conversion specifiers. For example, use "...%"pI"d..." rather
12343 than "...%"pEd"...".
12344 (pEd): Remove. All uses replaced with similar uses of pI.
12345 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12346 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12347 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12348 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12349 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12350 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12351 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12353 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12354 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12355 * print.c (safe_debug_print, print_object): Likewise.
12356 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12358 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12359 avoiding the 0 flag, which is not portable.
12360 * process.c (Fmake_network_process): Use pI to avoid cast.
12361 * region-cache.c (pp_cache): Likewise.
12362 * xdisp.c (decode_mode_spec): Likewise.
12363 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12364 behavior on 64-bit hosts with printf arg.
12365 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12366 (x_stop_queuing_selection_requests): Likewise.
12367 (x_get_window_property): Don't truncate byte count to an 'int'
12370 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12371 here, since it parses constructs like leading '-' and spaces,
12372 which are not wanted; and it overflows with large numbers.
12373 Instead, simply match F[0-9]+, which is what is wanted anyway.
12375 * alloc.c: Remove unportable assumptions about struct layout.
12376 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12377 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12378 (allocate_vectorlike, make_pure_vector): Use the new macros,
12379 plus offsetof, to remove unportable assumptions about struct layout.
12380 These assumptions hold on all porting targets that I know of, but
12381 they are not guaranteed, they're easy to remove, and removing them
12382 makes further changes easier.
12384 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12385 This doesn't fix a bug but makes the code clearer.
12386 (string_overrun_cookie): Now const. Use initializers that
12387 don't formally overflow signed char, to avoid warnings.
12388 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12389 can cause Emacs to crash when string overrun checking is enabled.
12390 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12391 multiple of sizeof (EMACS_INT); it need not be, if
12392 alignof(EMACS_INT) < sizeof (EMACS_INT).
12393 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12395 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12402 supposed to be handshaking. (Bug#8556)
12403 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12405 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

12410 (handle_user_signal): Break into debugger when debug-on-event
12411 matches the current signal symbol.
12413 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12415 * alloc.c (check_sblock, check_string_bytes)
12416 (check_string_free_list): Convert to standard C.
12418 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12420 * w32.c (emacs_gnutls_push): Fix typo.
12422 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12424 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12425 "cast to pointer from integer of different size".
12427 Improve doprnt and its use in verror. (Bug#8545)
12428 * doprnt.c (doprnt): Document the set of format control sequences
12429 supported by the function. Use SAFE_ALLOCA instead of always
12432 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12433 is one byte too soon. Don't use xrealloc; instead xfree and
12436 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12438 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12441 * gnutls.c: Renamed global_initialized to
12442 gnutls_global_initialized. Added internals for the
12443 :verify-hostname-error, :verify-error, and :verify-flags
12444 parameters of `gnutls-boot' and documented those parameters in the
12445 docstring. Start callback support.
12446 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12447 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12448 on error. Return error code.
12449 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12450 (emacs_gnutls_read): Likewise.
12451 (Fgnutls_boot): Return handshake error code.
12452 (emacs_gnutls_handle_error): New function.

12508 changes in globals.h immediately force recompilation.
12509 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12510 $(CURDIR)/s/ms-w32.h.

12515 <char-direction-table>: Deleted.
12517 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12519 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12520 * doprnt.c: Include limits.h.
12521 (SIZE_MAX): New macro.
12522 (doprnt): Return a size_t value. 2nd arg is now size_t.
12523 Many local variables are now size_t instead of int or unsigned.
12524 Improve overflow protection. Support `l' modifier for integer
12525 conversions. Support %l conversion. Don't assume an EMACS_INT
12526 argument for integer conversions and for %c.
12528 * lisp.h (doprnt): Restore prototype.
12530 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12531 $(SRC)/character.h.
12533 * Makefile.in (base_obj): Add back doprnt.o.
12535 * deps.mk (doprnt.o): Add back prerequisites.
12536 (callint.o): Depend on character.h.
12538 * eval.c (internal_lisp_condition_case): Include the handler
12539 representation in the error message.
12540 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12541 when breaking from the loop.
12543 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12545 * callint.c (Fcall_interactively): When displaying error message
12546 about invalid control letter, pass the character's codepoint, not
12547 a pointer to its multibyte form. Improve display of the character
12548 in octal and display also its hex code.
12550 * character.c (char_string): Use %x to display the (unsigned)
12551 codepoint of an invalid character, to avoid displaying a bogus
12554 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12555 `error', not SYMBOL_NAME itself.
12557 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12558 character arguments to `error'.
12560 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12561 to `error' in error message about FINAL_CHAR argument. Make sure
12562 FINAL_CHAR is a character, and use %c when it is passed as
12563 argument to `error'.

12627 Define only if needed.
12629 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
12630 by pacifying GCC about it. Maybe it's time to retire it?
12631 * xfaces.c (USG, __TIMEVAL__): Likewise.
12633 * dispextern.h (struct redisplay_interface): Rename param
12634 to avoid shadowing.
12635 * termhooks.h (struct terminal): Likewise.
12636 * xterm.c (xembed_send_message): Likewise.
12638 * insdel.c (make_gap_smaller): Define only if
12639 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
12641 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
12644 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
12645 so that we aren't warned about unused symbols.
12647 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
12649 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
12651 * xfns.c (x_real_positions): Mark locals as initialized.
12653 * xmenu.c (xmenu_show): Don't use uninitialized vars.
12655 * xterm.c: Fix problems found by static analysis with other toolkits.
12656 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
12657 (x_dispatch_event): Declare static if USE_GTK, and
12658 define if USE_GTK || USE_X_TOOLKIT.
12659 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
12660 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
12661 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
12662 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
12664 * xmenu.c (menu_help_callback): Pointer type fixes.
12665 Use const pointers when pointing at readonly data. Avoid pointer
12666 signedness clashes.
12667 (FALSE): Remove unused macro.

12752 * nsfont.m: Fixed bugs in ns_get_family and
12753 ns_descriptor_to_entity that were caused by using free to

12757 --enable-checking=xmallocoverrun). xfree is now used to
12758 deallocate these memory blocks.

13109 * buffer.c (buffer_count): Remove unused var.
13111 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
13112 so that it's not optimized away.
13113 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13114 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13115 exported only to the debugger.
13117 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
13118 * atimer.h (run_all_atimers): Remove; not exported.
13120 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13121 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13122 was inaccessible from Lisp.
13123 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13124 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13126 alloc.c: Import and export fewer symbols, and remove unused items.
13127 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13129 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13130 it's not optimized away by whole-program optimization.
13131 (message_enable_multibyte, free_misc): Remove.
13132 (catchlist, handlerlist, mark_backtrace):
13133 Declare only if BYTE_MARK_STACK.
13134 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
13135 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
13136 (message_enable_multibyte): Remove decl.
13137 (free_misc, interval_free_list, float_block, float_block_index):
13138 (n_float_blocks, float_free_list, cons_block, cons_block_index):
13139 (cons_free_list, last_marked_index):
13141 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
13142 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13143 (mark_backtrace): Define only if BYTE_MARK_STACK.
13144 * xdisp.c (message_enable_multibyte): Now static.
13146 Declare Lisp_Object Q* variables to be 'static' if not exported.
13147 This makes it easier for human readers (and static analyzers)
13148 to see whether these variables are used from other modules.
13149 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13150 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13151 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
13152 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

13154 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
13155 * xmenu.c, xselect.c:
13156 Declare Q* vars static if they are not used in other modules.
13157 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
13158 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
13159 Remove decls of unexported vars.
13160 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13162 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13164 Make Emacs functions such as Fatom 'static' by default.
13165 This makes it easier for human readers (and static analyzers)
13166 to see whether these functions can be called from other modules.
13167 DEFUN now defines a static function. To make the function external
13168 so that it can be used in other C modules, use the new macro DEFUE.
13169 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13170 (Finit_image_library):
13171 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13172 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13173 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13174 Remove decls, since these functions are now static.
13175 (Funintern, Fget_internal_run_time): New decls, since these functions
13176 were already external.
13178 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13179 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
13180 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
13181 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
13182 * keyboard.c, keymap.c, lread.c:
13183 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
13184 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
13185 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13186 Mark functions with DEFUE instead of DEFUN,
13187 if they are used in other modules.
13188 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13189 decls for now-static functions.
13190 * buffer.h (Fdelete_overlay): Remove decl.
13191 * callproc.c (Fgetenv_internal): Mark as internal.
13192 * composite.c (Fremove_list_of_text_properties): Remove decl.

13196 * doc.c (Fdocumntation_property): New forward static decl.
13197 * eval.c (Ffetch_bytecode): New forward static decl.
13198 (Funintern): Remove extern decl; now in .h file where it belongs.
13199 * fileio.c (Fmake_symbolic_link): New forward static decl.
13200 * image.c (Finit_image_library): New forward static decl.
13201 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13202 * intervals.h (Fprevious_property_change):
13203 (Fremove_list_of_text_properties): Remove decls.
13204 * keyboard.c (Fthis_command_keys): Remove decl.
13205 (Fcommand_execute): New forward static decl.
13206 * keymap.c (Flookup_key): New forward static decl.
13207 (Fcopy_keymap): Now static.
13208 * keymap.h (Flookup_key): Remove decl.
13209 * process.c (Fget_process): New forward static decl.
13210 (Fprocess_datagram_address): Mark as internal.

13221 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13223 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13226 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13228 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13229 when at ZV. (Bug#8487)
13231 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13233 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13235 * keyboard.c (parse_tool_bar_item): Likewise.
13236 * sound.c (sound_cleanup, alsa_close): Likewise.
13237 * termcap.c (tgetent): Likewise.
13238 * xfns.c (x_default_font_parameter): Likewise.
13239 * xsettings.c (read_and_apply_settings): Likewise.
13241 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13242 (overrun_check_free): Protoize.
13244 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13246 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13247 since callers should never pass a negative size.
13248 Change the signature to match that of plain 'read' and 'write'; see
13249 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13250 * lisp.h: Update prototypes of emacs_write and emacs_read.
13252 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13254 * xdisp.c (redisplay_window): Don't try to determine the character
13255 position of the scroll margin if the window start point w->startp
13256 is outside the buffer's accessible region. (Bug#8468)
13258 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13260 Fix write-region and its subroutines for buffers > 2GB.
13261 * fileio.c (a_write, e_write): Modify declaration of arguments and
13262 local variables to support buffers larger than 2GB.
13263 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13265 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13266 argument, local variables, and return value.
13268 * lisp.h: Update prototypes of emacs_write and emacs_read.
13270 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13272 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13274 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13276 Fix more problems found by GCC 4.6.0's static checks.
13278 * xdisp.c (vmessage): Use a better test for character truncation.
13280 * charset.c (load_charset_map): <, not <=, for optimization,
13281 and to avoid potential problems with integer overflow.
13282 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13283 * casetab.c (set_identity, shuffle): Likewise.
13284 * editfns.c (Fformat): Likewise.
13285 * syntax.c (skip_chars): Likewise.
13287 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13288 This also lets GCC 4.6.0 generate slightly better loop code.
13290 * callint.c (Fcall_interactively): <, not <=, for optimization.
13291 (Fcall_interactively): Count the number of arguments produced,
13292 not the number of arguments given. This is simpler and lets GCC
13293 4.6.0 generate slightly better code.
13295 * ftfont.c: Distingish more carefully between FcChar8 and char.
13296 The previous code passed unsigned char * to a functions like
13297 strlen and xstrcasecmp that expect char *, which does not
13298 conform to the C standard.
13299 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13300 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13301 char * when the C standard requires it.
13303 * keyboard.c (read_char): Remove unused var.
13305 * eval.c: Port to Windows vsnprintf (Bug#8435).
13306 Include <limits.h>.
13307 (SIZE_MAX): Define if the headers do not.
13308 (verror): Do not give up if vsnprintf returns a negative count.
13309 Instead, grow the buffer. This ports to Windows vsnprintf, which
13310 does not conform to C99. Problem reported by Eli Zaretskii.
13311 Also, simplify the allocation scheme, by avoiding the need for
13312 calling realloc, and removing the ALLOCATED variable.
13314 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13316 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13317 But keep the doprint source code for now, as we might revamp it
13318 and use it again (Bug#8435).
13319 * lisp.h (doprnt): Remove.
13320 * Makefile.in (base_obj): Remove doprnt.o.
13321 * deps.mk (doprnt.o): Remove.
13323 error: Print 32- and 64-bit integers portably (Bug#8435).
13324 Without this change, on typical 64-bit hosts error ("...%d...", N)
13325 was used to print both 32- and 64-bit integers N, which relied on
13326 undefined behavior.
13327 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13328 * lisp.h (error, verror): Mark as printf-like functions.
13329 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13330 Report overflow in size calculations when allocating printf buffer.
13331 Do not truncate output string at its first null byte.
13332 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13333 Truncate the output at a character boundary, since vsnprintf does not
13335 * charset.c (check_iso_charset_parameter): Convert internal
13336 character to string before calling 'error', since %c now has the
13338 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13339 overflow when computing char to be passed to 'error'. Do not
13340 pass Lisp_Object to 'error'; pass the integer instead.
13341 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13342 formatted with plain %d.
13344 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13346 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13348 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13350 * xterm.c (x_catch_errors): Remove duplicate declaration.
13352 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13354 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13356 2011-04-10 Jim Meyering <meyering@redhat.com>
13358 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13359 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13360 return ssize_t not "int", and use size_t as the buffer length.
13361 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13362 * gnutls.h: Update declarations.
13363 * process.c (read_process_output): Use ssize_t, to match.
13364 (send_process): Likewise.
13366 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13368 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13370 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13372 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13373 Use unsigned char, to match FcChar8 type definition.
13375 * xterm.c (handle_one_xevent):
13376 * xmenu.c (create_and_show_popup_menu):
13377 * xselect.c (x_decline_selection_request)
13378 (x_reply_selection_request): Avoid type-punned deref of X events.
13380 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13382 Fix some uses of `int' instead of EMACS_INT.
13383 * search.c (string_match_1, fast_string_match)
13384 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13385 (scan_buffer, find_next_newline_no_quit)
13386 (find_before_next_newline, search_command, Freplace_match)
13387 (Fmatch_data): Make some `int' variables be EMACS_INT.
13389 * xdisp.c (display_count_lines): 3rd argument and return value now
13390 EMACS_INT. All callers changed.
13391 (pint2hrstr): Last argument is now EMACS_INT.
13393 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13394 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13395 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13396 (decode_coding_utf_16, decode_coding_emacs_mule)
13397 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13398 (decode_coding_ccl, decode_coding_charset)
13399 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13400 (decode_coding_iso_2022, decode_coding_emacs_mule)
13401 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13402 <char_offset, last_offset>: Declare EMACS_INT.

13406 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13407 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13409 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13410 (encode_invocation_designation): Last argument P_NCHARS is now
13412 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13413 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13415 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13418 * ccl.c (Fccl_execute_on_string): Declare some variables
13421 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13423 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13425 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13427 * process.c (Fformat_network_address): Doc fix.
13429 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13431 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13433 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13435 * keyboard.c (read_char): Call Lisp function help-form-show,
13436 instead of using internal_with_output_to_temp_buffer.
13437 (Qhelp_form_show): New var.
13438 (syms_of_keyboard): Use DEFSYM macro.
13440 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13447 (list_processes_1): Delete.
13449 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13451 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13453 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13455 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13457 Fix more problems found by GCC 4.6.0's static checks.
13459 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13461 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13463 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13465 * xdisp.c (vmessage): Mark as a printf-like function.
13467 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13469 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13471 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13472 printf-like functions.

13474 to system-supplied API.
13476 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13478 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13479 This avoids several warnings with gcc -Wstrict-overflow.
13480 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13481 directly, rather than having caller test rule sign. This avoids
13482 some unnecessary tests.
13483 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13484 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13485 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13487 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13488 (xfont_open): Avoid unnecessary tests.
13490 * composite.c (composition_gstring_put_cache): Use unsigned integer.

13499 by using the new macro.
13501 * textprop.c (set_text_properties_1): Change while to do-while,
13502 since the condition is always true at first.
13504 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13505 (interval_deletion_adjustment): Return unsigned value.
13508 * process.c (list_processes_1, create_pty, read_process_output):

13524 * print.c (print_error_message): Avoid int overflow.
13526 * font.c (font_list_entities): Redo for clarity,
13527 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13529 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13530 (font_score): Avoid potential overflow in diff calculation.
13532 * fns.c (substring_both): Remove var that is set but not used.
13533 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13535 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13537 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13538 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13539 can always succeed if overflow has undefined behavior.
13541 * search.c (boyer_moore, wordify): Remove vars set but not used.
13542 (wordify): Omit three unnecessary tests.
13544 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13545 All callers changed. This avoids the need for an unused var.
13547 * casefiddle.c (casify_region): Remove var that is set but not used.
13549 * dired.c (file_name_completion): Remove var that is set but not used.
13551 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13553 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13554 (Finsert_file_contents): Remove unnecessary code checking fd.
13556 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13557 Check for integer overflow on size calculations.
13559 * buffer.c (Fprevious_overlay_change): Remove var that is set
13562 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13563 Remove vars that are set but not used.
13564 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13565 (timer_check_2): Mark vars as initialized.
13567 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13569 * image.c (lookup_image): Remove var that is set but not used.
13570 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13572 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13573 that are set but not used.
13575 * xfns.c (make_invisible_cursor): Don't return garbage
13576 if XCreateBitmapFromData fails (Bug#8410).
13578 * xselect.c (x_get_local_selection, x_handle_property_notify):
13579 Remove vars that are set but not used.
13581 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13582 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13584 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13585 Remove var that is set but not used.
13586 (scroll_bar_windows_size): Now size_t, not int.
13587 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13588 Check for overflow.
13590 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13591 (map_tty_color) [!defined MSDOS]: Likewise.
13593 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13595 * coding.c: Remove vars that are set but not used.
13596 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13597 All callers changed.
13598 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13599 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13600 (decode_coding_charset): Remove vars that are set but not used.
13602 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13603 that is set but not used.
13605 * print.c (print_object): Remove var that is set but not used.
13607 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13608 The gnulib version avoids calling malloc in the usual case,
13609 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13610 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13611 * filelock.c (current_lock_owner): Likewise.
13612 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13613 * sysdep.c: Include allocator.h, careadlinkat.h.
13614 (emacs_no_realloc_allocator): New static constant.
13615 (emacs_readlink): New function.
13616 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13617 ../lib/careadlinkat.h.
13619 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13621 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13622 first non-nil return value).

13633 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13634 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13636 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13637 and thereabouts. All callers changed.
13638 (get_per_char_metric): Remove parameter `f', unused since
13639 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13641 2011-04-02 Jim Meyering <meyering@redhat.com>
13643 do not dereference NULL upon failed strdup
13644 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13645 (ns_get_family): Likewise.
13647 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13649 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13651 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13653 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13656 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13658 Add lexical binding.
13660 * window.c (Ftemp_output_buffer_show): New fun.
13661 (Fsave_window_excursion):
13662 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13664 * lread.c (lisp_file_lexically_bound_p): New function.
13665 (Fload): Bind Qlexical_binding.
13666 (readevalloop): Remove `evalfun' arg.
13667 Bind Qinternal_interpreter_environment.
13668 (Feval_buffer): Bind Qlexical_binding.
13669 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13671 (syms_of_lread): Declare `lexical-binding'.
13673 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13675 * keyboard.c (eval_dyn): New fun.
13676 (menu_item_eval_property): Use it.
13678 * image.c (parse_image_spec): Use Ffunctionp.
13680 * fns.c (concat, mapcar1): Accept byte-code-functions.
13682 * eval.c (Fsetq): Handle lexical vars.
13683 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13684 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13685 (FletX, Flet): Obey lexical binding.
13686 (Fcommandp): Handle closures.
13687 (Feval): New `lexical' arg.
13688 (eval_sub): New function extracted from Feval. Use it almost
13689 everywhere where Feval was used. Look up vars in lexical env.
13691 (Ffunctionp): Move from subr.el.
13692 (Ffuncall): Handle closures.
13693 (apply_lambda): Remove `eval_flags'.
13694 (funcall_lambda): Handle closures and new byte-code-functions.
13695 (Fspecial_variable_p): New function.
13696 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13697 but without exporting it to Lisp.
13699 * doc.c (Fdocumentation, store_function_docstring):
13700 * data.c (Finteractive_form): Handle closures.
13702 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13705 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13707 (exec_byte_code): New function extracted from Fbyte_code to handle new
13708 calling convention for byte-code-functions. Add new byte-codes.
13710 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13712 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13714 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13716 * xdisp.c (redisplay_internal): Fix prototype.
13718 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13720 * xdisp.c (SCROLL_LIMIT): New macro.
13721 (try_scrolling): Use it when setting scroll_limit.
13722 Limit scrolling to 100 screen lines.
13723 (redisplay_window): Even when falling back on "recentering",
13724 position point in the window according to scroll-conservatively,
13725 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13727 (try_scrolling): When point is above the window, allow searching
13728 as far as scroll_max, or one screenful, to compute vertical
13729 distance from PT to the scroll margin position. This prevents
13730 try_scrolling from unnecessarily failing when
13731 scroll-conservatively is set to a value slightly larger than the
13732 window height. Clean up the case of PT below the margin at bottom
13733 of window: scroll_max can no longer be INT_MAX. When aggressive
13734 scrolling is in use, don't let point enter the opposite scroll
13735 margin as result of the scroll.
13736 (syms_of_xdisp) <scroll-conservatively>: Document the
13737 threshold of 100 lines for never-recentering scrolling.
13739 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13741 * dispextern.h (move_it_by_lines):

13744 (message_log_check_duplicate): Remove parameters `prev_bol' and
13745 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13746 (redisplay_internal): Remove parameter `preserve_echo_area',
13747 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13749 * indent.c (Fvertical_motion):
13750 * window.c (window_scroll_pixel_based, Frecenter):
13751 Don't pass `need_y_p' to `move_it_by_lines'.
13753 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13755 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13756 steal a few bits to be more compact.
13757 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13758 Remove unneeded casts.
13760 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13762 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13764 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13765 binding" message (bug#7967).
13767 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13769 Fix more problems found by GCC 4.6.0's static checks.
13771 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13772 Remove unused local var.
13774 * editfns.c (Fmessage_box): Remove unused local var.
13776 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13777 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13778 Omit unused local vars.
13779 * window.c (shrink_windows): Omit unused local var.
13780 * menu.c (digest_single_submenu): Omit unused local var.
13781 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13782 Omit unused local var.
13784 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13785 Don't assume string length fits in int.
13786 (keyremap_step, read_key_sequence): Use size_t for sizes.
13787 (read_key_sequence): Don't check last_real_key_start redundantly.
13789 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13790 instead of alloca (Bug#8344).
13792 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13793 (Fbacktrace_frame): Don't assume nframes fits in int.
13795 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13797 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13800 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13802 * cm.c (calccost): Turn while-do into do-while, for clarity.
13804 * keyboard.c (syms_of_keyboard): Use the same style as later
13805 in this function when indexing through an array. This also
13806 works around GCC bug 48267.
13808 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13810 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13812 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13813 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13815 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13816 This avoids undefined behavior on integer overflow, and is a bit
13817 more convenient anyway since it is compared to a size_t variable.
13819 Variadic C functions now count arguments with size_t, not int.
13820 This avoids an unnecessary limitation on 64-bit machines, which
13821 caused (substring ...) to crash on large vectors (Bug#8344).

13831 * fns.c (concat): Likewise.
13832 * frame.c (x_set_frame_parameters): Likewise.
13833 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13834 0 if not found, not -1. All callers changed.
13836 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13837 (stack_copy_size): Now size_t, not int.
13838 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13840 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13842 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13843 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13844 All callers changed.
13846 * lisp.h (multibyte_char_to_unibyte):
13847 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13848 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13859 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13860 don't set the hook to nil, but remove the offending function instead.
13861 (Qcommand_hook_internal): Remove, unused.
13862 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13863 Vcommand_hook_internal.

13866 (funcall_nil, funcall_not): New functions.
13867 (run_hook_with_args): Call each function through a `funcall' argument.

13881 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13882 All callers changed.
13884 * w32.c (_wsa_errlist): Use braces for struct initializers.
13886 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

14004 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
14006 * w32term.c (x_set_glyph_string_clipping):
14007 Don't pass uninitialized region to CombineRgn.

14031 2011-03-23 Julien Danjou <julien@danjou.info>
14033 * term.c (Fsuspend_tty, Fresume_tty):
14034 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14035 * window.c (temp_output_buffer_show):
14036 * insdel.c (signal_before_change):
14037 * frame.c (Fhandle_switch_frame):
14038 * fileio.c (Fdo_auto_save):

14041 * cmds.c (internal_self_insert):
14042 * callint.c (Fcall_interactively):
14043 * buffer.c (Fkill_all_local_variables):
14044 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14046 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14047 unconditionally since it does the check itself.
14049 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14051 Fix more problems found by GCC 4.5.2's static checks.
14053 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14054 the first time through the loop, since we know p0 < p1 then.
14055 This also avoids a gcc -Wstrict-overflow warning.
14057 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14058 leading to a memory leak, possible in functions like
14059 load_charset_map_from_file that can allocate an unbounded number
14060 of objects (Bug#8318).
14062 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14063 that could (at least in theory) be that large.
14065 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14066 This is less likely to overflow, and avoids undefined behavior if
14067 overflow does occur. All callers changed. Use strtoul to scan
14068 for the unsigned long integer.
14069 (pint2hrstr): Simplify and tune code slightly.
14070 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14072 * scroll.c (do_scrolling): Work around GCC bug 48228.
14073 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

14078 This also avoids a warning with gcc -Wstrict-overflow.
14080 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14083 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14085 * process.c (Fmake_network_process): Use socklen_t, not int,
14086 where POSIX says socklen_t is required in portable programs.
14087 This fixes a porting bug on hosts like 64-bit HP-UX, where
14088 socklen_t is wider than int (Bug#8277).
14089 (Fmake_network_process, server_accept_connection):
14090 (wait_reading_process_output, read_process_output):
14093 * process.c: Rename or move locals to avoid shadowing.

14103 Make tparam.h and terminfo.c consistent.
14104 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14105 Include tparam.h instead, since it declares them.
14106 * cm.h (PC): Remove extern decl; tparam.h now does this.
14107 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14108 * terminfo.c: Include tparam.h, to check interfaces.
14109 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14110 (tparam): Adjust signature to match interface in tparam.h;
14111 this removes some undefined behavior. Check that outstring and len
14112 are zero, which they always are with Emacs.
14113 * tparam.h (PC, BC, UP): New extern decls.
14115 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14116 (xftfont_open): Rename locals to avoid shadowing.
14118 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14119 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

14128 * xml.c (make_dom): Now static.
14130 * composite.c (composition_compute_stop_pos): Rename local to
14132 (composition_reseat_it): Remove unused locals.
14133 (find_automatic_composition, composition_adjust_point): Likewise.
14134 (composition_update_it): Mark var as initialized.
14135 (find_automatic_composition): Mark vars as initialized,
14136 with a FIXME (Bug#8290).

14140 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14141 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14142 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14143 to avoid shadowing.
14145 * textprop.c (property_change_between_p): Remove; unused.
14147 * intervals.c (interval_start_pos): Now static.
14149 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14152 Rename locals to avoid shadowing.
14154 * sound.c (wav_play, au_play, Fplay_sound_internal):
14155 Fix pointer signedness.
14156 (alsa_choose_format): Remove unused local var.
14157 (wav_play): Initialize a variable to 0, to prevent undefined
14158 behavior (Bug#8278).
14160 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14162 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14164 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14165 clobbering (Bug#8298).
14166 * sysdep.c (sys_subshell): Likewise.
14167 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14169 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14170 This should get cleaned up, so that child_setup has the
14171 same signature on all platforms.
14173 * callproc.c (call_process_cleanup): Now static.
14174 (relocate_fd): Rename locals to avoid shadowing.
14176 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14178 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14179 not to be necessary, and produces flickering.
14181 2011-03-20 Glenn Morris <rgm@gnu.org>
14183 * config.in: Remove file.
14185 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14187 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14188 are now in src/globals.h.
14189 (syms_of_minibuf): Remove spurious & from previous change.
14191 2011-03-20 Leo Liu <sdl.web@gmail.com>
14193 * minibuf.c (completing-read-function): New variable.
14194 (completing-read-default): Rename from completing-read.
14195 (completing-read): Call completing-read-function.
14197 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14199 * xfaces.c (Fx_load_color_file):
14200 Read color file from absolute filename (bug#8250).
14202 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14204 * makefile.w32-in: Update dependencies.
14206 2011-03-17 Eli Zaretskii <eliz@gnu.org>
14208 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

14215 (sigchld_handler): Now static.
14217 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14218 That way, the code declares only the vars that it needs.
14219 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
14220 * s/cygwin.h (PTY_ITERATION): Likewise.
14221 * s/darwin.h (PTY_ITERATION): Likewise.

14228 (CONSTANTLIM): Remove; unused.
14229 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14230 Define only if needed.
14232 * unexelf.c (unexec): Name an expression,
14233 to avoid gcc -Wbad-function-cast warning.
14234 Use a different way to cause a compilation error if anyone uses
14235 n rather than nn, a way that does not involve shadowing.
14236 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14238 * deps.mk (unexalpha.o): Remove; unused.
14240 New file unexec.h, the (simple) interface for unexec (Bug#8267).
14241 * unexec.h: New file.
14242 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
14243 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
14244 Depend on unexec.h.
14245 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
14246 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
14247 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
14248 Change as necessary to match prototype in unexec.h.
14250 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

14267 (font_sort_entities): Mark var as initialized.
14269 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
14271 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

14303 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14304 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14305 some of which prompt warnings from gcc -Wbad-function-cast.
14306 (Fformat_time_string, Fencode_time, Finsert_char):
14307 (Ftranslate_region_internal, Fformat):
14308 Rename or remove local vars to avoid shadowing.
14309 (Ftranslate_region_internal): Mark var as initialized.
14311 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
14314 * lisp.h (eassert): Check that the argument compiles, even if
14315 ENABLE_CHECKING is not defined.
14317 * data.c (Findirect_variable): Name an expression, to avoid
14318 gcc -Wbad-function-cast warning.

14330 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
14331 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
14333 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
14334 (GC_STRING_CHARS): Remove; not used.
14335 (Fmemory_limit): Cast sbrk's returned value to char *.
14337 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14338 avoids undefined behavior in theory.

14343 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14344 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14345 to use the following functions instead of these macros.
14346 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14347 EMACS_INT, since callers assume the returned value fits in int.
14348 (upcase1): Likewise, for UPCASE_TABLE.
14349 (uppercasep, lowercasep, upcase): New static inline functions.
14350 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14355 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14356 (regex_compile, re_search_2, re_match_2_internal):
14357 Remove unused local vars.
14358 (FREE_VAR): Rewrite so as not to use empty "else",
14359 which gcc can warn about.
14360 (regex_compile, re_match_2_internal): Mark locals as initialized.
14361 (RETALLOC_IF): Define only if needed.
14362 (WORDCHAR_P): Likewise. This one is never needed, but is used
14363 only in a comment talking about a compiler bug, so put inside
14364 the #if 0 of that comment.
14365 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14366 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14369 * search.c (boyer_moore): Rename locals to avoid shadowing.
14370 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
14371 (PREV_CHAR_BOUNDARY): Likewise.
14373 * search.c (simple_search): Remove unused var.
14375 * dired.c (compile_pattern): Move decl from here ...

14383 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14384 Rename locals to avoid shadowing.
14385 (Fvertical_motion): Mark locals as initialized.
14387 * casefiddle.c (casify_object, casify_region): Now static.
14388 (casify_region): Mark local as initialized.
14390 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14392 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14393 New macros, so that the caller can use some names other than
14394 gcpro1, gcpro2, etc.
14395 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14397 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14398 argument, for consistency with GCPRO2_VAR, etc: it is now the
14399 prefix of the variable, not the variable itself. All uses
14401 * dired.c (directory_files_internal, file_name_completion):
14402 Rename locals to avoid shadowing.
14404 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14405 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14406 dired.c's scmp function, had undefined behavior.
14407 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14408 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14409 * buffer.h: ... to here, because these macros use current_buffer,
14410 and the new implementation with inline functions needs to have
14411 current_buffer in scope now, rather than later when the macros
14413 (downcase, upcase1): New static inline functions.
14414 (DOWNCASE, UPCASE1): Reimplement using these functions.
14415 This avoids undefined behavior in expressions like
14416 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14417 from race conditions in accessing the global variables
14418 case_temp1 and case_temp2.
14419 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14420 * lisp.h (case_temp1, case_temp2): Remove their decls.
14421 * character.h (ASCII_CHAR_P): Move from here ...
14422 * lisp.h: ... to here, so that the inline functions mentioned
14423 above can use them.
