325 * w32.c (init_environment): Change the default values of many
326 environment variables in dflt_envvars[] to NULL, to avoid pushing
327 them into environment when they were not already defined. Remove
328 the code that deletes site-lisp subdirectories from the default
329 value of EMACSLOADPATH, as it is no longer needed.
330 (check_windows_init_file): Now external, not static. Use
331 Vload_path as is, without adding anything, as this function is now

364 Remove unnecessary casts involving pointers.
365 These casts are no longer needed now that we assume C89 or later,

380 Remove unnecessary pointer casts.
381 * alloc.c (record_xmalloc): New function.
382 * lisp.h (record_xmalloc): New decl.
383 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
384 more like a function. This is because the pointer cast is not
385 needed. All uses changed.
386 * print.c (print_string, print_error_message): Avoid length recalc.
388 Improve fix for macroexp crash with debugging (Bug#12118).
389 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
390 ARRAY_MARK_FLAG when checking subscripts, because ASET is
391 not supposed to be invoked from the garbage collector.
392 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
393 (gc_aset): New function, which is like ASET but can be
394 used in the garbage collector.

412 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
414 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

423 with addition of handling of symlinks and support for 'lstat'. If
424 possible, get file's attributes and security information by
425 handle, not by name. Produce S_IFLNK bit for symlinks, when
427 (stat, lstat): New functions, call 'stat_worker'.
428 (symlink, readlink, careadlinkat): Rewritten to create and resolve
429 symlinks when the underlying filesystem supports them.
431 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
433 Fix macroexp crash on Windows with debugging (Bug#12118).
434 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
435 checking subscripts; problem introduced with the recent
436 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
437 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
438 since it's used in non-static inline functions now.
440 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
441 Don't assume buffer size fits in 'int'. Remove unused local.
443 Use C99-style 'extern inline' if available.

465 are compiled into code.
466 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
467 (INLINE_HEADER_END): New macros.

962 * xdisp.c (syms_of_xdisp): Likewise.
963 * xfns.c (syms_of_xfns): Likewise.
965 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
967 Fast save_excursion_save and save_excursion_restore.
968 * lisp.h (struct Lisp_Excursion): New data type.
969 (PVEC_EXCURSION): New pseudovector type.

986 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
987 emacs.c, as this is a more-suitable home. Had this been done earlier
988 the fix for 12036 would have avoided some of the problems noted in
989 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
990 would have been more obvious.
991 * emacs.c: Do not include <verify.h>; no longer needed.
992 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
993 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
994 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
995 Remove; now done in lisp.h.

1000 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1001 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1002 not be usable in #if. This simplifies things.
1004 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1006 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
1008 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

1011 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1012 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1013 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1014 Adjust to changes in lisp.h and emacs.c, by using
1015 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1016 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1017 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1018 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1019 instead of gdb_valbits.
1020 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1021 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1022 instead of gdb_array_mark_flag.
1023 (xboolvector): Get size from $->size, not $->header.size.
1024 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1025 (xreload, hook-run, hookpost-run): Remove.
1026 * emacs.c: Include <verify.h>.
1027 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1028 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1030 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1031 (gdb_USE_LSB_TAG): New enum constants.
1032 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1033 Also define these as enum constants, so they're visible to GDB.
1034 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1035 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1036 as constants, so they're visible to GDB.

1038 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
1039 Now enum constants, not macros, so they're visible to GDB.
1040 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1041 more convenient now. All uses changed.
1042 (VALMASK) [USE_LSB_TAG]: Also define in this case.
1043 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
1045 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

1052 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
1053 add argument, tune behavior, and adjust all callers.
1055 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1057 Use typedef for EMACS_INT, EMACS_UINT.
1058 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1059 than macros. This simplifies debugging in the usual case, since
1060 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1061 and it allows expressions involving EMACS_INT casts.
1062 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1064 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

1076 Adjust buffer text indirection counters at the end of Fkill_buffer.
1077 * buffer.c (Fkill_buffer): Adjust indirection counters when the
1078 buffer is definitely dead. This should really fix an issue reported
1079 by Christoph Scholtes again. (Bug#12007).
1080 (init_buffer_once): Initialize indirection counters of
1081 buffer_defaults and buffer_local_symbols (for sanity and safety).
1083 2012-07-24 Eli Zaretskii <eliz@gnu.org>
1085 * xdisp.c (init_iterator): Don't compute dimensions of truncation
1086 and continuation glyphs on tooltip frames, leave them at zero.
1087 Avoids continued lines in tooltips. (Bug#11832)
1089 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

1114 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1116 Swap buffer text indirection counters in Fbuffer_swap_text.
1117 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1118 This avoids crash reported by Christoph Scholtes at
1119 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1121 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1123 * nsmenu.m (Popdown_data): New struct.

1146 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
1148 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
1149 as it's limited by the amount of memory, not by INT_MAX.
1151 2012-07-21 Eli Zaretskii <eliz@gnu.org>
1153 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
1154 in special-event-map. See the discussion at

1235 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
1236 'for_each_per_buffer_object_at'.

1304 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1306 * eval.c (Fdefvar): Don't check constants since we only set the var if
1307 it's not yet defined anyway (bug#11904).
1309 * lisp.h (last_undo_boundary): Declare new var.
1310 * keyboard.c (command_loop_1): Set it.
1311 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
1312 were auto-added by the command loop (bug#11774).
1314 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
1316 * w32font.c (Qsymbol): Remove local definition.

1876 Remove "#define unix" that is no longer needed (Bug#11905).
1877 * s/aix4-2.h (unix): Remove; no longer needed.
1879 EMACS_TIME simplification (Bug#11875).
1880 This replaces macros (which typically do not work in GDB)
1881 with functions, typedefs and enums, making the code easier to debug.
1882 The functional style also makes code easier to read and maintain.
1883 * systime.h: Include <sys/time.h> on all hosts, not just if
1884 WINDOWSNT, since 'struct timeval' is needed in general.
1885 (EMACS_TIME): Now a typedef, not a macro.
1886 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
1888 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
1889 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
1890 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
1891 (EMACS_TIME_LE): Now functions, not macros.
1892 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
1893 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1894 which are not functions. All uses rewritten to use:
1895 (make_emacs_time): New function.
1896 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1897 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1898 not functions. All uses rewritten to use the following, respectively:
1899 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1900 (add_emacs_time, sub_emacs_time): New functions.
1901 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1902 * fileio.c (Fcopy_file):
1903 * xterm.c (XTflash): Get the current time closer to when it's used.
1904 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1910 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
1911 * frame.c (Fmake_terminal_frame):
1912 * gtkutil.c (get_utf8_string):
1914 * nsmenu.m (ns_update_menubar):
1915 * regex.c (regerror):
1916 Prefer memcpy to strncpy and strncat when either will do.
1917 * fileio.c (Fsubstitute_in_file_name):
1918 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1919 (menu_separator_name_p):
1920 * nsmenu.m (ns_update_menubar):
1921 Prefer memcmp to strncmp when either will do.
1922 * nsterm.m: Include <ftoastr.h>.
1924 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1925 Prefer snprintf to strncpy.
1926 * nsterm.m (ns_term_init):
1927 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1928 * nsterm.m (ns_term_init):
1929 Avoid the need for strncpy, by using build_string or
1930 make_unibyte_string directly. Use dtoastr, not snprintf.
1931 * process.c (Fmake_network_process): Diagnose service names that
1932 are too long, rather than silently truncating them or creating
1933 non-null-terminated names.
1934 (Fnetwork_interface_info): Likewise, for interface names.
1935 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1936 Prefer sprintf to strncat.
1937 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1938 Prefer vsnprintf to vsprintf + strncpy.
1940 2012-07-10 Glenn Morris <rgm@gnu.org>
1942 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1943 Clarify fallback case.
1945 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1947 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1948 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1949 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1950 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1951 where argument type is known to be a Lisp_Cons.
1953 2012-07-10 Tom Tromey <tromey@redhat.com>
1955 * bytecode.c (BYTE_CODE_THREADED): New macro.
1956 (BYTE_CODES): New macro. Replaces all old byte-code defines.

1961 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1963 Optimize pure C strings initialization.
1964 * lisp.h (make_pure_string): Fix prototype.
1965 (build_pure_c_string): New function, defined as static inline. This
1966 provides a better opportunity to optimize away calls to strlen when
1967 the function is called with compile-time constant argument.
1968 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1969 argument, adjust users accordingly. Use build_pure_c_string where
1971 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1972 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1973 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1975 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1977 Avoid calls to strlen in miscellaneous functions.
1978 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1979 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1980 * lread.c (openp): Likewise.
1982 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1984 Avoid calls to strlen in path processing functions.
1985 * fileio.c (file_name_as_directory): Add comment. Change to add
1986 srclen argument and return the length of result. Adjust users
1988 (directory_file_name): Fix comment. Change to add srclen argument,
1989 swap 1st and 2nd arguments to obey the common convention. Adjust
1991 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1993 2012-07-10 Glenn Morris <rgm@gnu.org>
1995 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1996 Move PENDING_OUTPUT_COUNT definition to configure.
1998 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1999 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
2000 * s/gnu.h (DATA_START): Move definitions to configure.
2002 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2003 We include usg5-4-common.h, which defines them both.
2005 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2006 O_RDONLY already includes it).
2008 Stop ns builds setting the EMACSLOADPATH environment variable.
2009 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2010 Now it does not set EMACSLOADPATH, just returns the load-path string.
2011 * nsterm.h: Update accordingly.
2012 * lread.c [HAVE_NS]: Include nsterm.h.
2013 (init_lread) [HAVE_NS]: Use ns_load_path.
2014 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
2016 2012-07-09 Glenn Morris <rgm@gnu.org>
2018 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2019 since the included bsd-common.h does so.
2021 Stop ns builds setting the EMACSPATH environment variable.
2022 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2023 (ns_init_paths): Do not set EMACSPATH.
2024 * nsterm.h (ns_exec_path): Add it.
2025 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2028 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2030 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2032 * process.c (wait_reading_process_output): 'waitchannels' was unset
2033 when read_kbd || !NILP (wait_for_cell); fix this.
2035 Add GCC-style 'const' attribute to functions that can use it.
2036 * character.h (char_resolve_modifier_mask):
2037 * keyboard.h (make_ctrl_char):
2038 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
2039 (init_character_once, next_almost_prime, init_fns, init_image)
2040 (flush_pending_output, init_sound):
2041 * mem-limits.h (start_of_data):
2042 * menu.h (finish_menu_items):
2043 Add ATTRIBUTE_CONST.

2045 Declare the dummy function with ATTRIBUTE_CONST.
2046 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2047 Add decls with ATTRIBUTE_CONST.
2049 Minor improvements to make_formatted_string.
2050 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2051 where int is good enough, as vsprintf returns an int.
2052 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2054 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2056 Use make_formatted_string to avoid double length calculation.
2057 * lisp.h (make_formatted_string): New prototype.
2058 * alloc.c (make_formatted_string): New function.
2059 * buffer.c (Fgenerate_new_buffer_name): Use it.
2060 * dbus.c (syms_of_dbusbind): Likewise.

2063 * frame.c (make_terminal_frame, set_term_frame_name)
2064 (x_report_frame_params): Likewise.
2065 * image.c (gs_load): Likewise.
2066 * minibuf.c (get_minibuffer): Likewise.

2081 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2083 Move marker debugging code under MARKER_DEBUG.
2084 * marker.c (MARKER_DEBUG): Move marker debugging code under
2085 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2086 for bootstrap with --enable-checking (~3x slowdown reported
2087 by Juanma Barranquero <lekktu@gmail.com>).
2088 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2090 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2092 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2093 See <http://bugs.gnu.org/11825#29>.
2095 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2097 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2098 has no font, use the frame's font. (Bug#11813)
2099 (display_line): Add commentary about displaying truncation glyphs
2101 (produce_special_glyphs): Move here from term.c.
2103 * term.c (produce_special_glyphs): Move to xdisp.c.
2105 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2108 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2110 * xdisp.c (display_line): Avoid warning about implicit declaration
2113 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2115 * lisp.h: Remove empty conditional.
2117 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2119 * lread.c (load_path_check): Now static.
2121 Fix some minor --with-ns problems found by static checking.
2122 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2123 (x_set_font) [!HAVE_X_WINDOWS]:
2124 * image.c (xpm_load_image) [HAVE_NS]:
2125 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2126 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2127 Remove unused local.
2128 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2129 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2130 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2131 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2132 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2133 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2134 Fix pointer signedness problem.
2135 * xfaces.c (FRAME_X_FONT_TABLE):
2136 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2138 2012-07-07 Glenn Morris <rgm@gnu.org>
2140 * lread.c (load_path_check): New function, split from init_lread.
2141 (init_lread): Reorganize. Motivation:
2142 If EMACSLOADPATH is set, check/warn about that rather than the
2143 defaults, which we are not going to use. Hence we can remove
2144 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2145 Don't warn if site-lisp directories are missing.
2146 If not installed, start from a blank load-path, since
2147 PATH_LOADSEARCH refers to the eventual installation directories.
2149 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2151 Support truncation and continuation glyphs on GUI frames, when
2152 fringes are disabled. (Bug#11832)
2153 * xdisp.c (init_iterator): Get dimensions of truncation and
2154 continuation glyphs even if on GUI frames. Adjust
2155 it->last_visible_x on GUI frames when the left or right fringes,
2156 or both, are absent.
2157 (start_display, move_it_in_display_line_to): Handle the case of a
2158 GUI frame without a fringe to display continuation or truncation
2160 (insert_left_trunc_glyphs): Support GUI frames: make sure
2161 truncation glyphs overwrite enough glyphs from the current line to
2162 have sufficient space in pixels.
2163 (display_line): Support truncation and continuation glyphs on GUI
2164 frames. If some spare pixels are left on the line after inserting
2165 the truncation glyphs, fill that space with a stretch glyph of a
2166 suitably computed width.
2168 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2169 produce_glyphs, to support GUI sessions.
2171 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2173 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2175 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2177 Do not require float-time's arg to fit in time_t (Bug#11825).
2178 This works better on hosts where time_t is unsigned, and where
2179 float-time is applied to the (negative) difference between two times.
2180 * editfns.c (decode_time_components): Last arg is now double *,
2181 not int *, and means to store all the result as a double, without
2182 worrying about whether the seconds part fits in time_t.
2183 All callers changed.
2184 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2185 All callers changed.
2186 (Ffloat_time): Do not fail merely because the specified time falls
2187 outside of time_t range.
2189 2012-07-07 Glenn Morris <rgm@gnu.org>
2191 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2195 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2197 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2198 Update dependencies.
2200 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2202 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2204 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
2205 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
2206 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2207 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2208 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2209 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2211 * xfont.c (compare_font_names): Redo to omit the need for casts.
2213 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2215 * xfns.c (Fx_change_window_property): Doc fix.
2216 * w32fns.c (Fx_change_window_property): Doc fix.
2218 * w32fns.c (Fx_window_property): Accept the same arguments as the
2219 X Windows version. Doc fix.
2220 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2222 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2223 Eli Zaretskii <eliz@gnu.org>
2225 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2226 Windows-specific code from nt/config.nt moved here.
2227 Obsolete settings removed.
2229 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2231 * process.c: Avoid unnecessary calls to gettime.
2232 (wait_reading_process_output): Don't get the time of day
2233 when gobbling data immediately and not waiting, as there's no need
2234 for it in that case. This removes a FIXME.
2236 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2238 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2239 is defined (Bug#11768).
2241 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2243 Fix marker debugging code.

2245 if buffer is not multibyte.
2246 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2247 Call byte_char_debug_check with correct arguments.
2249 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2251 Compile marker debugging code only if ENABLE_CHECKING is defined.
2252 * marker.c (byte_char_debug_check, count_markers):
2253 Use only if ENABLE_CHECKING is defined.
2254 (byte_debug_flag): Remove.
2255 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2256 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2258 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2260 Avoid code repetition in marker-related functions.
2261 * marker.c (attach_marker): New function.
2262 (Fset_marker, set_marker_restricted, set_marker_both)
2263 (set_marker_restricted_both): Use it.

2285 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2286 * window.c (save_window_save): Likewise.
2288 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2290 Do not use Fdelete_overlay in delete_all_overlays
2291 to avoid redundant calls to unchain_overlay.
2292 * buffer.c (drop_overlay): New function.
2293 (delete_all_overlays, Fdelete_overlay): Use it.
2294 * minibuf.c (get_minibuffer): Fix comment.
2296 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2298 Port to OpenBSD 5.1 amd64.
2299 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2300 This is needed for OpenBSD, and should be harmless on all BSD systems.
2301 Also, include <sys/sysctl.h>, as it should be available on all
2302 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2303 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2304 use p_pid member, not kp_proc.pid.
2306 2012-07-06 Glenn Morris <rgm@gnu.org>
2308 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2310 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2312 More xmalloc and related cleanup.
2313 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2314 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2319 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2320 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2321 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2323 Omit needless casts involving void * pointers and allocation.
2324 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2325 as the former is more robust if P's type is changed.
2326 Prefer xzalloc to xmalloc + memset 0.
2327 Simplify malloc-or-realloc to realloc.
2328 Don't worry about xmalloc returning a null pointer.
2329 Prefer xstrdup to xmalloc + strcpy.
2330 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2332 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2333 alloca of a constant.
2335 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2337 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2338 hscroll is larger than the line width. Fixes long and futile
2339 looping inside extend_face_to_end_of_line (on a TTY) producing
2340 glyphs that are not needed and thrown away.
2342 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2344 * marker.c (set_marker_restricted_both): Simplify by using
2347 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2349 * editfns.c (region_limit): Simplify by using clip_to_bounds.
2351 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
2353 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
2354 not defined (Bug#11768).
2355 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2356 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2357 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2358 followed by gtk_box_set_homogeneous (Bug#11768).
2359 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2360 (update_theme_scrollbar_width, xg_create_scroll_bar):
2361 Use gtk_scrollbar_new (Bug#11768).
2362 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2363 (is_box_type): New function (Bug#11768).
2364 (xg_tool_item_stale_p): Call is_box_type.
2365 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2366 with default display (Bug#11768).
2368 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2370 * xdisp.c (window_hscroll_limited): New function.
2371 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2372 coordinates when window's hscroll is set to insanely large
2375 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2377 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2378 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2380 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2383 * lisp.h (xzalloc): New prototype. Omit needless casts.
2384 * alloc.c (xzalloc): New function. Omit needless casts.

2436 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2438 * fileio.c (time_error_value): Check the right error number.
2439 Problem reported by Troels Nielsen in
2440 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2442 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2444 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2445 This should be fixed in a better way; see Eli Zaretskii in
2446 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2447 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2449 * fileio.c (time_error_value): Rename from special_mtime.
2450 The old name's problems were noted by Eli Zaretskii in
2451 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2453 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2454 This variable's comment says Emacs needs at least one GDB-visible
2455 symbol of type enum pvec_type, to work around GDB problems.
2456 The symbol's value doesn't matter.
2458 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2459 that causes compilation to fail on pre-C99 compilers.
2461 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2463 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2464 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2466 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2468 * buffer.c (init_buffer_once): Fix initialization of
2469 headers for buffer_defaults and buffer_local_symbols.
2470 Reported by Juanma Barranquero <lekktu@gmail.com>.
2472 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2474 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2475 * lisp.h (enum pvec_type): Use fewer bits.
2476 (PSEUDOVECTOR_SIZE_BITS): New constant.
2477 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2478 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2479 change in pvec_type.
2480 (PSEUDOVECTOR_TYPEP): New macro.
2481 (TYPED_PSEUDOVECTORP): Use it.
2482 * fns.c (internal_equal): Adapt code to extract pvectype.
2483 * emacs.c (gdb_pvec_type): Update type.
2484 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2485 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2486 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2487 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2488 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2489 abusing vector->header.next.nbytes.
2490 (live_vector_p): Use PVEC_TYPE.
2491 (mark_object): Adapt code to extract pvectype. Use switch.
2493 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2495 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2496 Tighten new eassert a bit.
2498 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2500 Fix compilation with --enable-gcc-warnings and -O1
2502 * doprnt.c (doprnt): Change type of tem to int, initialize
2503 to avoid compiler warning. Add eassert.
2504 * search.c (simple_search): Initialize match_byte to avoid
2505 compiler warning. Add eassert.
2507 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2509 Avoid weird behavior with large horizontal scrolls.
2510 Without this change, for example, large hscroll values would
2511 mess up Emacs's display on Fedora 15 x86, presumably due to
2512 overflows in int calculations in the display code.
2513 Also, if buffers had long lines, Emacs would freeze.
2514 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2515 (set_window_hscroll): New function, containing the old guts of
2516 Fset_window_hscroll. Return the clipped value.
2517 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2518 This avoids the need to check against PTRDIFF_MAX.
2520 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2522 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2524 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2526 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2528 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2529 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2530 since GCC 4.4.6 issues a bogus warning for them.
2532 Fix bugs in file timestamp newness comparisons.
2533 * fileio.c (Ffile_newer_than_file_p):
2534 * lread.c (Fload): Use full timestamp resolution of files,
2535 not just the 1-second resolution, so that files that are only
2536 slightly newer still count as newer.
2537 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2538 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2540 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2542 * fileio.c: Improve handling of file time marker. (Bug#11852)
2543 (special_mtime): New function.
2544 (Finsert_file_contents, Fverify_visited_file_modtime):
2545 Use it to set special mtime values consistently.
2547 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2549 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2550 marker for non-existing file. (Bug#11852)
2552 2012-07-03 Glenn Morris <rgm@gnu.org>
2554 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2555 and did not make it into globals.h).
2557 2012-07-03 Tom Tromey <tromey@redhat.com>
2559 * window.c (Fset_window_margins, Fset_window_fringes)
2560 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2561 * textprop.c (Fprevious_property_change): No longer static.
2562 * syntax.c (Fsyntax_table_p): No longer static.
2563 * process.c (Fget_process, Fprocess_datagram_address): No longer

2577 * dired.c (Ffile_attributes): No longer static.
2578 * composite.c (Fcomposition_get_gstring): No longer static.
2579 * callproc.c (Fgetenv_internal): No longer static.
2581 * ccl.h: Remove EXFUNs.
2582 * buffer.h: Remove EXFUNs.
2583 * dispextern.h: Remove EXFUNs.
2584 * intervals.h: Remove EXFUNs.
2585 * fontset.h: Remove EXFUN.
2586 * font.h: Remove EXFUNs.
2587 * dosfns.c (system_process_attributes): Remove EXFUN.
2588 * keymap.h: Remove EXFUNs.
2589 * lisp.h: Remove EXFUNs.
2590 * w32term.h: Remove EXFUNs.
2591 * window.h: Remove EXFUNs.
2592 * xsettings.h: Remove EXFUN.
2593 * xterm.h: Remove EXFUN.
2595 2012-07-03 Glenn Morris <rgm@gnu.org>
2597 * lisp.h (Frandom): Make it visible to C.
2598 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2599 buffer for invisible buffers. (Bug#1229)
2601 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2603 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2604 values which aren't power of 2.
2605 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2606 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2609 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2611 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2613 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2615 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2617 * alloc.c (allocate_vector_block): Remove redundant
2618 calls to mallopt if DOUG_LEA_MALLOC is defined.
2619 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2620 avoid calls to mallopt if zero_vector is returned.
2622 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2624 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2625 is enabled, avoid dereferencing NULL current_sblock if
2628 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2630 Cleanup basic buffer management.
2631 * buffer.h (struct buffer): Change layout to use generic vector
2632 marking code. Fix some comments. Change type of 'clip_changed'
2633 to bitfield. Remove unused #ifndef old.
2634 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2635 (GET_OVERLAYS_AT): Fix indentation.
2636 (for_each_per_buffer_object_at): New macro.
2637 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2638 (Fbuffer_local_variables): Use it.
2639 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2640 * alloc.c (allocate_buffer): Adjust to match new layout of
2641 struct buffer. Fix comment.
2642 (mark_overlay): New function.
2643 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2644 Lisp area of struct buffer.
2645 (mark_object): Use it. Adjust marking of misc objects
2646 and related comments.
2648 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2650 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2651 wrapper that is not needed because the wrapped code is a no-op (zero
2652 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2653 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2655 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2657 * alloc.c (mark_buffer): Simplify. Remove prototype.
2658 (mark_object): Add comment. Reorganize marking of vector-like
2659 objects. Use CHECK_LIVE for all vector-like objects except buffers
2660 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2661 redundant calls to mark_vectorlike for bool vectors.
2663 2012-06-30 Glenn Morris <rgm@gnu.org>
2665 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2667 * epaths.in (PATH_SITELOADSEARCH): New.
2668 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2669 This is rather than relying on --enable-locallisppath elements
2670 having "site-lisp" in their names. (Bug#10208#25, 11658)
2672 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2674 * w32proc.c (sys_select): Accept and ignore one more argument.
2676 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2678 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2679 (pselect) [!MS_DOS]: Redirect to sys_select.
2681 * sysdep.c: Don't include dos.h and dosfns.h.
2683 * process.c (sys_select):
2684 * msdos.c (sys_select): Accept one more argument and ignore it.
2686 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2687 adapt data types and code to that.
2690 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2691 which clashes with the gnulib function of the same name.
2693 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2695 * font.c (font_style_to_value, font_style_symbolic)
2696 (font_prop_validate_style): Add type checks for values in
2699 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2701 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2704 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2706 * xdisp.c (try_window_id): Undo last change.
2708 * w32.c (getwd): Adjust commentary about startup_dir.
2709 (init_environment): Always call sys_access, even in non-MSVC
2710 builds. Don't chdir to the directory of the Emacs executable.
2711 This undoes code from 1997 which was justified by the need to
2712 "avoid conflicts when removing and renaming directories". But its
2713 downside was that every relative file name was being interpreted
2714 relative to the directory of the Emacs executable, which can never
2715 be TRT. In particular, it broke sys_access when called with
2716 relative file names.
2717 (sys_access): Map GetLastError to errno.
2719 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2721 * window.h (struct window): Change type of 'fringes_outside_margins'
2722 to bitfield. Fix comment. Adjust users accordingly.
2723 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2725 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2728 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2730 * gnutls.c (emacs_gnutls_handshake):
2731 Add QUIT to make the loop interruptible.
2733 2012-06-29 Glenn Morris <rgm@gnu.org>
2735 * charset.c (init_charset): Make lack of etc/charsets fatal.
2737 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2739 * editfns.c (region_limit): Fix type mismatch.
2741 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2743 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2744 undefined. Convert from xassert to eassert.
2745 * nsmenu.m: Convert from xassert to eassert.
2746 * nsterm.m: Likewise.
2748 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2750 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2752 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2754 Avoid integer overflow on scroll-left and scroll-right.
2755 * window.c (HSCROLL_MAX): New macro.
2756 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2757 overflow when requested scroll falls outside ptrdiff_t range.
2759 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

2911 Use sprintf return value instead of invoking strlen on result.
2912 In the old days this wasn't portable, since some sprintf
2913 implementations returned char *. But they died out years ago and
2914 Emacs already assumes sprintf returns int.
2915 Similarly for float_to_string.
2916 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2924 Use sprintf or float_to_string result to avoid need to call strlen.
2925 * data.c (Fnumber_to_string):
2926 Use make_unibyte_string, since the string must be ASCII.
2927 * lisp.h, print.c (float_to_string): Now returns int length.
2928 * term.c (produce_glyphless_glyph):
2929 Use sprintf result rather than recomputing it.
2931 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2932 * Makefile.in (ALL_CFLAGS):
2933 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2962 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2964 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2967 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2969 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2970 instead of truncating it to 63 (admittedly a generous limit).

3030 * keyboard.c (kbd_buffer_get_event):
3031 * process.c (Faccept_process_output):
3032 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3033 This improves on the previous patch, which introduced a bug
3034 when time_t is unsigned and as wide as intmax_t.
3035 See <http://bugs.gnu.org/9000#51>.
3037 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3066 language ID in the event parameters.
3068 * w32term.c (w32_read_socket): Put the new keyboard codepage into

3092 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
3093 Privately reported by Herbert J. Skuhra.

3100 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3102 Support higher-resolution time stamps (Bug#9000).
3103 The time stamps are only nanosecond-resolution at the C level,
3104 since that's the best that any real-world system supports now.
3105 But they are picosecond-resolution at the Lisp level, as that's
3106 easy, and leaves room for future OS improvements.
3108 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3111 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3112 Don't get current time unless it's needed.
3114 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3115 now provides it if it's absent.
3116 (start_atimer): Port to higher-res time stamps.
3117 Check for time stamp overflow. Don't get current time more
3118 often than is needed.
3120 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3121 Include systime.h, not time.h.
3122 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3124 * dired.c: Include stat-time.h.
3125 (Ffile-attributes): File times now have higher resolution.

3128 (struct image): Timestamp now has higher resolution.
3130 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3131 has at least microseconds now. All uses removed.
3132 (update_frame, update_single_window, update_window, update_frame_1)
3133 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3135 * editfns.c (time_overflow): Now extern.
3136 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3137 (float-time, Fformat_time_string, Fcurrent_time_string)
3138 (Fcurrent_time_zone): Accept and generate higher-resolution

3141 (decode_time_components, lisp_seconds_argument): New functions.
3142 (make_time): Now static.
3143 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3144 Report an error if the time is invalid, rather than having the caller
3147 * fileio.c: Include <stat-time.h>
3148 (Fcopy_file): Copy higher-resolution time stamps.
3149 Prefer to set the time stamp via a file descriptor if that works.
3150 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3151 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3152 (Fvisited_file_modtime, Fset_visited_file_modtime):
3153 Support higher-resolution time stamps.
3155 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3157 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3159 * image.c (prepare_image_for_display, clear_image_cache)
3160 (lookup_image): Port to higer-resolution time stamps.
3162 * keyboard.c (start_polling, bind_polling_period):
3163 Check for time stamp overflow.
3164 (read_char, kbd_buffer_get_event, timer_start_idle)
3165 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3166 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3167 Port to higher-resolution time stamps. Do not assume time_t is signed.
3168 (decode_timer): New function. Timers are now vectors of length 9,
3169 not 8, to accommodate the picosecond component.
3170 (timer_check_2): Use it.
3172 * nsterm.m (select_timeout, timeval_subtract): Remove.
3173 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3174 as they're a bit more accurate and handle overflow better.
3175 (ns_select): Change prototype to be compatible with pselect.
3176 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3177 * nsterm.h (ns_select): Adjust prototype.
3179 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3180 us-resolution time stamps.
3181 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3183 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3185 * lisp.h (time_overflow): New decl.
3186 (wait_reading_process_output): First arg is now intmax_t, not int,
3187 to accommodate larger waits.
3189 * process.h (struct Lisp_Process.read_output_delay):
3190 Now counts nanoseconds, not microseconds.
3191 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3193 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3194 (wait_reading_process_output):
3195 Port to ns-resolution time stamps.
3196 (Faccept_process_output, wait_reading_process_output):
3197 Check for time stamp overflow. Do not assume time_t is signed.
3198 (select_wrapper): Remove; we now use pselect.
3199 (Fprocess_attributes): Now generates ns-resolution time stamps.
3201 * sysdep.c: Include utimens.h. Don't include utime.h
3202 or worry about struct utimbuf; gnulib does that for us now.
3203 (gettimeofday): Remove; gnulib provides a substitute.
3204 (make_timeval): New function.
3205 (set_file_times): Now sets ns-resolution time stamps.
3206 New arg FD; all uses changed.
3207 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3208 (system_process_attributes):
3209 Now returns ns-resolution time stamp. All uses changed.
3210 Check for time stamp overflow.
3212 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3213 provides a substitute now.
3215 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3216 since it guarantees struct timespec.
3217 (EMACS_TIME): Now struct timespec, so that we can support
3218 ns-resolution time stamps.
3219 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3220 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3221 (EMACS_USECS): Remove.
3222 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3223 so multiply the arg by 1000 before storing it.
3224 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3226 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3227 Port to ns-resolution time stamps.
3228 (EMACS_TIME_NEG_P): Remove; replaced by....
3229 (EMACS_TIME_SIGN): New macro.
3230 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3231 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

3233 (make_timeval, make_lisp_time, decode_time_components): New decls.
3234 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3235 that it mishandled time_t overflow. You can't compare by subtracting!
3236 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3237 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3239 * term.c: Include <sys/time.h>.
3240 (timeval_to_Time): New function, for proper overflow wraparound.
3241 (term_mouse_position, term_mouse_click): Use it.

3276 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3277 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

3328 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3329 gets killed during executing of this function (Bug#11665).
3330 Try to always return Qt when the buffer has been actually killed.
3331 (Vkill_buffer_query_functions): In doc-string say that functions
3332 run by this hook should not change the current buffer.
3334 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3336 Fix recently-introduced process.c problems found by static checking.

3359 argument were confusing, as 'eassert' typically does not evaluate
3362 * coding.c (produce_chars): Use ptrdiff_t, not int.
3364 * xterm.c (x_draw_underwave): Check for integer overflow.
3365 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3550 code works fine either way, and efficiency is not a concern here,
3551 as the union type is for debugging, not for production.
3552 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3553 Use an inline function on all platforms when using the union type,
3554 since this is simpler and 'static inline' can be used portably

3665 * alloc.c (allocate_vectorlike): Fix last change.

3669 Block-based vector allocation of small vectors.

3671 adjust comment accordingly.
3672 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

3698 * doprnt.c (doprnt): Truncate multibyte char correctly.
3699 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3700 would mishandle a string argument "Xc" if X was a multibyte
3701 character of length 2: it would truncate after X's first byte
3702 rather than including all of X.
3704 2012-06-06 Chong Yidong <cyd@gnu.org>

3719 (temacs$(EXEEXT)): Disable memory randomization for the temacs
3720 binary via PaX flags if the paxctl utility is available.
3721 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3722 Restore PaX flags to their default. (Bug#11398)

3726 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
3729 2012-06-03 Chong Yidong <cyd@gnu.org>
3731 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
3732 (note_mode_line_or_margin_highlight): If there is no help echo,
3733 use mode-line-default-help-echo. Handle the case where the mouse
3734 position is past the end of the mode line string.
3736 * buffer.c (buffer_local_value_1): New function, split from
3737 Fbuffer_local_value; can return Qunbound.
3738 (Fbuffer_local_value): Use it.
3739 (Vmode_line_format): Docstring tweaks.

3748 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
3749 and DEFVAR it. Update all users.
3751 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
3753 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3755 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3756 Convert pctcpu and pctmem to Lisp float properly.
3757 Let the compiler fold better, as 100.0/0x8000 is exact.
3759 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3761 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3764 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3766 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3768 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3770 For a 'struct window', replace some Lisp_Object fields to
3771 bitfields where appropriate, remove unused fields.
3772 * window.h (struct window): Remove unused 'last_mark_x' and
3773 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3774 change it's type from Lisp_Object to bitfield.
3775 Change type of 'force_start', 'optional_new_start',
3776 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3777 fields from Lisp_Object to bitfield. Adjust users accordingly.
3779 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3781 Pacify gcc -Wdouble-precision when using Xaw.
3782 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3783 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3784 Use 'float' consistently, rather than 'float' in most places
3785 and 'double' in a couple of places.
3787 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3789 * xdisp.c (handle_stop): Detect whether we have overlay strings
3790 loaded by testing it->current.overlay_string_index to be
3791 non-negative, instead of checking whether n_overlay_strings is
3792 positive. (Bug#11587)
3794 2012-05-31 Chong Yidong <cyd@gnu.org>
3796 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3798 * doc.c (Fsubstitute_command_keys): Doc fix.
3800 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3802 * search.c (search_buffer): Remove calls to
3803 r_alloc_inhibit_buffer_relocation, as it is now called by
3804 maybe_unify_char, which was the cause of relocation of buffer text
3807 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3809 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3810 for the duration of call to load_charset, to avoid problems with
3811 callers of maybe_unify_char that access buffer text through C
3814 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3815 decrement the inhibition flag, instead of just setting or
3818 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3820 Remove obsolete '#define static' cruft.
3821 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3822 This #undef was "temporary" in 2000; it is no longer needed
3823 now that '#define static' has gone away.
3824 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3825 (gray_bitmap_bits): Remove; no longer needed.
3826 All uses replaced with definiens.
3827 * xterm.c: Include "bitmaps/gray.xbm".
3829 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3831 Clean up __executable_start, monstartup when --enable-profiling.
3832 The following changes affect the code only when profiling.
3833 * dispnew.c (__executable_start): Rename from safe_bcopy.
3834 Define only on platforms that need it.
3835 * emacs.c: Include <sys/gmon.h> when profiling.
3836 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3837 (__executable_start): Remove decl, since lisp.h does it now.
3838 (safe_bcopy): Remove decl; no longer has that name.
3839 (main): Coalesce #if into single bit of code, for simplicity.
3840 Cast pointers to uintptr_t, since standard libraries want integers
3842 * lisp.h (__executable_start): New decl.
3844 2012-05-31 Glenn Morris <rgm@gnu.org>
3846 * image.c (Fimagemagick_types): Doc fix.
3848 2012-05-30 Jim Meyering <meyering@redhat.com>
3850 * callproc.c (Fcall_process_region): Include directory component

3865 * lread.c (read1): Tiny simplification.
3867 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3869 Do not create empty overlays with the evaporate property (Bug#9642).
3870 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3871 Bug#9642, but explicitly check that the buffer the overlay would
3872 be moved to is live and rearrange lines to make sure that errors
3873 will not put the overlay in an inconsistent state.
3874 (Fdelete_overlay): Cosmetics.
3876 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3878 * w32term.c (my_bring_window_to_top): New function.
3879 (x_raise_frame): Use handle returned by DeferWindowPos, which
3880 could be different from the original one.

3884 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3885 by calling BringWindowToTop.
3887 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3888 (WM_EMACS_END): Increase by one.
3890 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3892 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3893 This avoids undefined behavior that might cause the eassert
3894 to not catch an out-of-range value.
3896 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3898 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3899 Update dependencies.
3901 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3903 * bidi.c (bidi_mirror_char): Fix last change.
3905 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3907 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3908 when referring to sectname field in printf format.
3910 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3912 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3913 Only r_alloc_inhibit_buffer_relocation needed to be added;
3914 the others were already declared.
3916 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3917 before checking whether it's out of range. Put the check inside
3919 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3921 2012-05-27 Ken Brown <kbrown@cornell.edu>
3923 * callproc.c (Fcall_process): Restore a line that was accidentally
3924 commented out in the 2011-02-13 change (bug#11547).
3926 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3928 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3929 defined on ralloc.c.
3931 * buffer.c [REL_ALLOC]: Remove prototypes of
3932 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3933 they are now on lisp.h.
3935 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3937 * search.c (search_buffer): Use it to inhibit relocation of buffer
3938 text while re_search_2 is doing its job, because re_search_2 is
3939 passed C pointers to buffer text. (Bug#11519)
3941 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3944 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3945 state after an additional call to move_it_in_display_line_to, keep
3946 the values of it->max_ascent and it->max_descent found for the
3948 (pos_visible_p): Revert the comparison against bottom_y to what it
3949 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3952 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3954 Fix coding-related core dumps with gcc -ftrapv.
3955 The code was computing A - B, where A and B are pointers, and B is
3956 random garbage. This can lead to core dumps on platforms that
3957 have special pointer registers, and it also leads to core dumps on
3958 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3959 A - B only when B is initialized properly.
3960 * coding.c (coding_set_source, coding_set_destination): Return void.
3961 (coding_change_source, coding_change_destinations): New functions,
3962 with the old behaviors of coding_set_source and coding_set_destination.
3963 All callers that need an offset changed to use these new functions.
3965 2012-05-26 Glenn Morris <rgm@gnu.org>
3967 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3969 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3971 Extend mouse support on W32 text-mode console.
3972 * xdisp.c (draw_row_with_mouse_face):
3973 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3975 * w32console.c: Include window.h.
3976 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3978 (initialize_w32_display): Initialize mouse-highlight data.
3980 * w32inevt.c: Include termchar.h and window.h.
3981 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3982 moves, call note_mouse_highlight. If help_echo changed, call
3983 gen_help_event to produce help-echo message in the echo area.
3984 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3987 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3989 * lread.c (read1): Simplify slightly to avoid an overflow warning
3990 with GCC 4.7.0 on x86-64.
3992 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3994 * bidi.c (bidi_mirror_char): Revert last change: an int is
3995 definitely wide enough here.
3997 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3999 Fix integer width and related bugs (Bug#9874).
4000 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4001 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4002 (string_bytes, check_sblock, allocate_string_data):
4003 (compact_small_strings, Fmake_bool_vector, make_string)
4004 (make_unibyte_string, make_multibyte_string)
4005 (make_string_from_bytes, make_specified_string)
4006 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
4007 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4009 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4010 (allocate_pseudovector):
4011 Use int, not EMACS_INT, where int is wide enough.
4012 (inhibit_garbage_collection, Fgarbage_collect):
4013 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4014 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4015 int might not be wide enough.
4016 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4017 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4018 (bidi_at_paragraph_end, bidi_find_paragraph_start)
4019 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4020 (bidi_level_of_next_char, bidi_move_to_visually_next):
4021 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4022 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4023 (Fkill_buffer, Fset_buffer_major_mode)
4024 (advance_to_char_boundary, Fbuffer_swap_text)
4025 (Fset_buffer_multibyte, overlays_at, overlays_in)
4026 (overlay_touches_p, struct sortvec, record_overlay_string)
4027 (overlay_strings, recenter_overlay_lists)
4028 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4029 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4030 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4031 (Foverlay_recenter, last_overlay_modification_hooks_used)
4032 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4033 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4034 (validate_region): Omit unnecessary test for b <= e,
4035 since that's guaranteed by the previous test.
4036 (adjust_overlays_for_delete): Avoid pos + length overflow.
4037 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4038 (report_overlay_modification):
4039 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4040 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4041 Omit pointer cast, which isn't needed anyway, and doesn't work
4042 after the EMACS_INT -> ptrdiff_t change.
4043 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4044 * buffer.h: Adjust decls to match defn changes elsewhere.
4045 (struct buffer_text, struct buffer):
4046 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4047 Use EMACS_INT, not int, where int might not be wide enough.
4048 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4049 not int, to avoid needless 32-bit limit on 64-bit hosts.
4050 (exec_byte_code): Use tighter memory-full test, one that checks
4051 for alloca overflow. Don't compute the address of the object just
4052 before an array, as that's not portable. Use EMACS_INT, not
4053 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4054 * callint.c (Fcall_interactively):
4055 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4056 * callproc.c (call_process_kill, Fcall_process):
4057 Don't assume pid_t fits into an Emacs fixnum.
4058 (call_process_cleanup, Fcall_process, child_setup):
4059 Don't assume pid_t fits into int.
4060 (call_process_cleanup, Fcall_process, delete_temp_file)
4061 (Fcall_process_region):
4062 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4063 (Fcall_process): Simplify handling of volatile integers.
4064 Use int, not EMACS_INT, where int will do.
4065 * casefiddle.c (casify_object, casify_region, operate_on_word)
4066 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4067 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4068 (casify_object): Avoid integer overflow when overallocating buffer.
4069 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4070 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4071 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4072 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4073 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4074 integers are now checked earlier. All uses replaced with XINT.
4076 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4077 For CCL_MapSingle, check that content and value are in int range.
4078 (ccl_driver, Fregister_code_conversion_map):
4079 Check that Vcode_version_map_vector is a vector.
4080 (resolve_symbol_ccl_program): Check that vector header is in range.
4081 Always copy the vector, so that we can check its contents reliably
4082 now rather than having to recheck each instruction as it's being
4083 executed. Check that vector words fit in 'int'.
4084 (ccl_get_compiled_code, Fregister_ccl_program)
4085 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4086 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4087 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4088 contents are in range.
4089 (Fccl_execute_on_string): Check that status is in range.
4090 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4091 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4092 Accept and return EMACS_INT, not int, because callers can pass values
4094 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4095 (multibyte_chars_in_text, parse_str_as_multibyte)
4096 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
4097 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4098 (string_escape_byte8, Fget_byte):
4099 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4100 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4101 avoid mishandling large integers.
4102 * character.h: Adjust decls to match defn changes elsewhere.
4103 * charset.c (load_charset_map_from_file, find_charsets_in_text)
4104 (Ffind_charset_region):
4105 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4106 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
4107 (load_charset_map_from_vector, Fdefine_charset_internal):
4108 Don't assume fixnum fits in int.
4109 (load_charset_map_from_vector, Fmap_charset_chars):
4110 Remove now-unnecessary CHECK_NATNUMs.
4111 (Fdefine_charset_internal): Check ranges here, more carefully.
4112 Don't rely on undefined behavior with signed left shift overflow.
4113 Don't assume unsigned int fits into fixnum, or that fixnum fits
4114 into unsigned int. Don't require max_code to be a valid fixnum;
4115 that's not true for gb10830 4-byte on a 32-bit host. Allow
4116 invalid_code to be a cons, for the same reason. Require code_offset
4117 to be a character. Avoid int overflow if max_char is close
4119 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4120 this is intended anyway and avoids some undefined behavior.
4121 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4122 INDEX_TO_CODE_POINT, as that's what it expects.
4123 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4124 * charset.h (DECODE_CHAR): Return int, not unsigned;
4125 this is what was intended anyway, and it avoids undefined behavior.
4126 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4127 integer-overflow issues.
4128 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4129 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4130 where the argument is EMACS_INT, and this behavior is not intended.
4131 * chartab.c (Fmake_char_table, Fset_char_table_range)
4132 (uniprop_get_decoder, uniprop_get_encoder):
4133 Don't assume fixnum fits in int.
4134 * cmds.c (move_point): New function, that does the gist of
4135 Fforward_char and Fbackward_char, but does so while checking
4136 for integer overflow more accurately.
4137 (Fforward_char, Fbackward_char): Use it.
4138 (Fforward_line, Fend_of_line, internal_self_insert)
4139 (internal_self_insert):
4140 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4141 Fix a FIXME, by checking for integer overflow when calculating
4142 target_clm and actual_clm.
4143 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
4144 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)
4145 (ASSURE_DESTINATION, coding_alloc_by_realloc)
4146 (coding_alloc_by_making_gap, alloc_destination)

4859 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
4861 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
4862 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
4863 * textprop.c, tparam.c (NULL): Remove.
4864 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
4865 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4866 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4867 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4868 * xterm.c (input_signal_count): Assume volatile works.
4870 2012-05-21 Ken Brown <kbrown@cornell.edu>
4872 * xgselect.c (xg_select): Fix first argument in call to 'select'
4875 2012-05-20 Ken Brown <kbrown@cornell.edu>
4877 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4878 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4880 2012-05-19 Ken Brown <kbrown@cornell.edu>
4882 * xfns.c (x_in_use): Remove `static' qualifier.
4883 * xterm.h (x_in_use): Declare.
4884 * xgselect.c: Include xterm.h.
4885 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4886 and `display_arg' (bug#9754).
4888 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4890 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4892 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4893 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4895 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4897 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4899 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4900 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4902 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4903 reference to image_cache->refcount.
4904 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4906 2012-05-17 Juri Linkov <juri@jurta.org>
4908 * search.c (Fword_search_regexp, Fword_search_backward)
4909 (Fword_search_forward, Fword_search_backward_lax)
4910 (Fword_search_forward_lax): Move functions to isearch.el
4911 (bug#10145, bug#11381).
4913 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4915 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4917 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4919 * lread.c (init_obarray): Declare Qt and Qnil as special.
4921 2012-05-14 Glenn Morris <rgm@gnu.org>
4923 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4924 Put "libexec" before "bin", for the sake of init_callproc_1.
4926 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4928 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4930 * unexaix.c: Port to more-recent AIX compilers.
4931 (report_error, report_error_1, make_hdr, copy_sym)
4932 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4933 Make arguments const char *, not char *, to avoid violations of C
4934 standard and to fix some AIX warnings reported by Gilles Pion.
4936 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4938 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4939 already have overlays loaded.
4940 (handle_single_display_spec): Before returning without displaying
4941 fringe bitmap, synchronize the bidi iterator with the main display
4942 iterator, by calling iterate_out_of_display_property.
4943 (iterate_out_of_display_property): Detect buffer iteration by
4944 testing that it->string is a Lisp string.
4945 (get_next_display_element): When the current object is exhausted,
4946 and there's something on it->stack, call set_iterator_to_next to
4947 proceed with what's on the stack, instead of returning zero.
4948 (set_iterator_to_next): If called at the end of a Lisp string,
4949 proceed to consider_string_end without incrementing string
4950 position. Don't increment display vector index past the end of
4951 the display vector. (Bug#11417)
4952 (pos_visible_p): Don't report a position visible when move_it_to
4953 stopped at the last line of window, which happens to be scanned
4954 backwards by the bidi iteration. (Bug#11464)
4956 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4958 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4959 and right-margin display specs even if the spec is invalid or we
4960 are on a TTY, and thus unable to display on the fringes.
4961 That's because the text with the property will not be displayed anyway,
4962 so we need to signal to the caller that this is a "replacing"
4963 display spec. This fixes display when the spec is invalid or we
4966 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4968 * unexaix.c (make_hdr): Fix typo in prototype.
4969 This bug broke the build on AIX. Problem reported by Gilles Pion.
4971 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4973 * keyboard.c (kbd_buffer_get_event): Read special events also in
4974 batch mode. (Bug#11415)
4976 2012-05-12 Glenn Morris <rgm@gnu.org>
4978 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4980 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4982 * lisp.mk (lisp): Add newcomment.elc.
4984 2012-05-12 Glenn Morris <rgm@gnu.org>
4986 * Makefile.in (MKDIR_P): New, set by configure.
4987 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4989 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4991 Remove unused function hourglass_started.
4992 * dispextern.h (hourglass_started):
4993 * w32fns.c (hourglass_started):
4994 * xdisp.c (hourglass_started): Remove.
4996 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4998 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4999 Update dependencies.
5001 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5003 * xgselect.c (xg_select): Put maxfds+1 into a var.
5004 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5006 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5008 2012-05-10 Dave Abrahams <dave@boostpro.com>
5010 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5011 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5013 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5015 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5016 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5017 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5018 Initialize xd_registered_buses.
5020 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5022 Untag more efficiently if USE_LSB_TAG.
5023 This is based on a proposal by YAMAMOTO Mitsuharu in
5024 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5025 For an admittedly artificial (nth 8000 longlist) benchmark on
5026 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5027 Emacs's overall text size by 1%.
5028 * lisp.h (XUNTAG): New macro.
5029 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5030 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5031 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5032 * eval.c (Fautoload):
5033 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5034 * frame.h (XFRAME): Use XUNTAG.
5036 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5037 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5038 Remove unportable assumptions about print widths of types like
5040 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5041 intptr_t when converting between pointer and integer, to avoid GCC
5042 warnings about wrong width.
5044 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5046 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5047 stack for each reader_thread, instead of defaulting to 8MB
5048 determined by the linker. This avoids failures in creating
5049 subprocesses on Windows 7, see the discussion in this thread:
5050 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5052 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5054 Fix up display of the *Minibuf-0* buffer in the mini window.
5055 * keyboard.c (read_char): Don't clear the echo area if there's no
5057 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5058 contents of *Minibuf-0*) if there's no message displayed in its stead.
5060 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5062 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5065 2012-05-06 Chong Yidong <cyd@gnu.org>
5067 * lisp.mk (lisp): Update.
5069 2012-05-05 Jim Meyering <meyering@redhat.com>
5071 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5073 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5075 * data.c (PUT_ERROR): New macro.
5076 (syms_of_data): Use it. Add new error type `user-error'.
5077 * undo.c (user_error): New function.
5078 (Fprimitive_undo): Use it.
5079 * print.c (print_error_message): Adjust print style for `user-error'.
5080 * keyboard.c (user_error): New function.
5081 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5083 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5085 Do not limit current-time-string to years 1000..9999.
5086 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5087 (Fcurrent_time_string): Support any year that is supported by the
5088 underlying localtime representation. Don't use asctime, as it
5089 has undefined behavior for years outside the range -999..9999.
5091 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5093 Fix race conditions involving setenv, gmtime, localtime, asctime.
5094 Without this fix, interrupts could mess up code that uses these
5095 nonreentrant functions, since setting TZ invalidates existing
5096 tm_zone or tzname values, and since most of these functions return
5097 pointers to static storage.
5098 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5099 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5100 Grow the critical sections to include not just invoking
5101 localtime/gmtime, but also accessing these functions' results
5102 including their tm_zone values if any, and any related TZ setting.
5103 (format_time_string): Last arg is now struct tm *, not struct tm **,
5104 so that the struct tm is saved in the critical section.
5105 All callers changed. Simplify allocation of initial buffer, partly
5106 motivated by the fact that memory allocation needs to be outside
5107 the critical section.
5109 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5111 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5112 with RESET_INTERVAL.
5114 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5115 Remove duplicated buffer name initialization.
5117 2012-05-02 Jim Meyering <jim@meyering.net>
5119 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5121 * xfns.c (x_window): Use xstrdup (Bug#11375).
5123 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5125 * xdisp.c (pos_visible_p): If already at a newline from the
5126 display string before the 'while' loop, don't walk back the glyphs
5127 from it3.glyph_row. Solves assertion violation when the display
5128 string begins with a newline (egg.el). (Bug#11367)
5130 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5132 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5135 2012-05-01 Glenn Morris <rgm@gnu.org>
5137 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5138 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5139 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5140 All were removed before 23.1.
5142 * dispnew.c: Remove HAVE_LIBNCURSES test;
5143 it is always true on relevant platforms.
5145 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5146 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5148 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5150 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5152 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5153 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5156 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5158 Do not avoid creating empty evaporating overlays (Bug#9642).
5159 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5160 That is, do not delete an evaporating overlay if it becomes
5161 empty after its bounds are adjusted to fit within its buffer.
5162 This fix caused other problems, and I'm reverting it until we get
5163 to the bottom of them.
5165 2012-04-27 Chong Yidong <cyd@gnu.org>
5167 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5169 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5171 * xdisp.c (pos_visible_p): If the window start position is beyond
5172 ZV, start the display from buffer beginning. Prevents assertion
5173 violation in init_iterator when the minibuffer window is scrolled
5176 * window.c (window_scroll_pixel_based): Likewise.
5178 2012-04-27 Chong Yidong <cyd@gnu.org>
5180 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5182 2012-04-27 Glenn Morris <rgm@gnu.org>
5184 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5185 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5187 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5189 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5190 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5192 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5194 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5195 display element, check also the underlying string or buffer
5196 character. (Bug#11341)
5198 * w32menu.c: Include w32heap.h.
5199 (add_menu_item): If the call to AppendMenuW (via
5200 unicode_append_menu) fails, disable Unicode menus only if we are
5201 running on Windows 9X/Me.
5203 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5205 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5206 (xgetint): Add missing shift for LSB tags.
5208 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5210 * keyboard.c (read_char): Don't wipe echo area for select window
5211 events: These might get delayed via `mouse-autoselect-window'
5214 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5216 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5217 manipulation of :loaded-from data.
5219 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5221 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5222 now a cons (bug#11311).
5224 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5226 Do not create empty overlays with the evaporate property (Bug#9642).
5227 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5228 if it becomes empty after its bounds are adjusted to fit within
5229 its buffer. Without this fix, in a nonempty buffer (let ((o
5230 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5231 yields an empty overlay that has the evaporate property, which is
5232 not supposed to happen.
5234 Fix minor GTK3 problems found by static checking.
5235 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5236 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5237 (struct _EmacsFixedClass, emacs_fixed_get_type):
5238 Move decls here from emacsgtkfixed.h, since they needn't be public.
5239 (emacs_fixed_get_type): Now static.
5240 (emacs_fixed_class_init): Omit unused local.
5241 (emacs_fixed_child_type): Remove; unused.

5243 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5244 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
5245 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5246 (EMACS_FIXED_GET_CLASS): Remove; unused.
5247 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5249 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5250 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5252 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5254 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5255 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5256 (__malloc_size_t, __malloc_ptrdiff_t):
5257 Remove. All uses removed, replaced by the definiens if needed,
5258 since we can assume C89 or better now.
5259 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5260 (protect_malloc_state, align, get_contiguous_space)
5261 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
5262 (malloc_atfork_handler_child, malloc_enable_thread)

5267 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5268 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5269 Define using prototypes, not old style.
5270 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5271 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5272 (align): Don't assume that signed integer overflow wraps around.
5273 Omit unused local var.
5274 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5275 (_free_internal_nolock, memalign, mallochook, reallochook):
5276 Omit no-longer-needed casts.
5277 (valloc): Use getpagesize, not __getpagesize.
5278 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
5279 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5281 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5283 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
5285 Move functions from C to Lisp. Make non-blocking method calls
5286 the default. Implement further D-Bus standard interfaces.
5288 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
5289 (QCdbus_request_name_allow_replacement)
5290 (QCdbus_request_name_replace_existing)
5291 (QCdbus_request_name_do_not_queue)

5332 Do not assume ptrdiff_t is the same width as 'int'.
5334 * alloc.c: Handle unusual debugging option combinations.
5335 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5336 since the two debugging options are incompatible.
5337 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5339 (mem_init, mem_insert, mem_insert_fixup):
5340 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5370 * print.c (print_preprocess): Only check print_depth if print-circle
5372 (print_object): Check for cycles even when print-circle is nil and
5373 print-gensym is t, but only check print_depth if print-circle is nil.
5375 2012-04-20 Chong Yidong <cyd@gnu.org>
5377 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5378 set the status to "failed" and ensure that sentinel is run.

5393 farther than the first row after the header line, if any.
5394 Don't consider the header-line row as "partially visible", even if

5432 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5433 New extern decls, to avoid calling undeclared functions.
5434 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5435 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5436 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

5458 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5460 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5477 Remove definition of GC_MARK_STACK, since the default now works.
5478 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5479 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5480 no longer the default.
5481 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5483 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5485 * lread.c (lisp_file_lexically_bound_p):

5495 * nsterm.m (constrainFrameRect): Always constrain when there is only
5496 one screen (Bug#10962).

5506 2012-04-11 Daniel Colascione <dancol@dancol.org>
5508 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5509 against is gone. It's better to use vfork now so that when Cygwin
5510 gains a new, working vfork, we use it automatically (bug#10398).
5512 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5533 being loaded (bug#10424).
5535 2012-04-09 Glenn Morris <rgm@gnu.org>
5537 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5538 not just in the obarray, before snarfing them. (Bug#11036)
5540 * Makefile.in ($(leimdir)/leim-list.el):

5565 * minibuf.c (Fread_variable): Callers changed.
5567 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5569 * xdisp.c (set_cursor_from_row): If the display string appears in
5570 the buffer at position that is closer to point than the position
5571 after the display string, display the cursor on the first glyph of
5572 the display string. Fixes cursor display when a 'display' text
5573 property immediately follows invisible text. (Bug#11094)
5575 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5577 composite.c: use 'double' consistently
5578 * composite.c (get_composition_id): Use 'double' consistently
5579 instead of converting 'float' to 'double' and vice versa; this is
5580 easier to understand and avoids a GCC warning.
5582 2012-04-09 Glenn Morris <rgm@gnu.org>
5584 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5585 preparation for dumping it with emacs. (Bug#4789)

5607 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5608 (mark_memory): Mark Lisp_Objects only if pointers might hide in

5627 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5628 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5629 [!WINDOWSNT]: New macros.
5630 (init_libxml2_functions, libxml2_loaded_p): New functions.
5631 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5632 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5633 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5634 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5636 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5637 Call init_libxml2_functions before calling libxml2 functions.
5638 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5640 * emacs.c: Don't include libxml/parser.h.

5642 xmlCleanupParser directly.
5644 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5646 2012-04-07 Eli Zaretskii <eliz@gnu.org>

5654 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5655 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5656 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5657 macros related to unification of CJK characters. For the details,
5658 see the discussion following the message here:
5659 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5661 2012-04-04 Chong Yidong <cyd@gnu.org>
5663 * keyboard.c (Vdelayed_warnings_list): Doc fix.

5675 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5677 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5678 position we get to after a call to move_it_to fails the
5679 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5680 only if we wind up in a string from display property. (Bug#11063)
5682 * window.c (Fdelete_other_windows_internal): Invalidate the row
5683 and column information about mouse highlight, so that redisplay
5684 restores it after reallocating the glyph matrices. (Bug#7464)
5686 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5687 string comes from a `display' text property, use the buffer
5688 position of that property as if we actually saw that position in
5690 (move_it_by_lines): Remove the assertion that
5691 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5692 violated when there's a before-string at the beginning of a line.
5695 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5697 * xdisp.c (append_space_for_newline): If the default face was
5698 remapped, use the remapped face for the appended newline.
5699 (extend_face_to_end_of_line): Use the remapped default face for
5700 extending the face to the end of the line.
5701 (display_line): Call extend_face_to_end_of_line when the default
5702 face was remapped. (Bug#11068)

5737 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5739 * s/ms-w32.h (tzname): Include time.h before redirecting to

5750 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5752 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5753 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5754 when fetching a multibyte character consumes more bytes than
5755 CHAR_BYTES returns, due to unification of CJK characters in
5756 string_char. (Bug#11073)
5758 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5760 * process.c (wait_reading_process_output): Handle pty disconnect
5761 by refraining from sending oneself a SIGCHLD (bug#10933).

5776 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5778 * w32proc.c (Fw32_set_console_codepage)
5779 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5789 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5790 it fit in a valid range (Bug#11003).
5792 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5794 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5795 that is not from display property, accept the row as a "cursor
5796 row" if one of the string's character has a non-nil `cursor'
5797 property. Fixes cursor positioning when there are newlines in
5798 overlay strings, e.g. in icomplete.el. (Bug#11035)
5800 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

5831 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5834 2012-03-03 Glenn Morris <rgm@gnu.org>
5836 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

5847 2012-03-02 Glenn Morris <rgm@gnu.org>
5849 * buffer.c (buffer-list-update-hook): Doc fix.
5851 2012-02-29 Eli Zaretskii <eliz@gnu.org>

5854 push_it before setting up the iterator for the first overlay
5855 string, even if we have an empty string loaded.
5856 (next_overlay_string): If there's an empty string on the iterator
5857 stack, pop the stack. (Bug#10903)
5859 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5861 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5862 Suggested by Stefan Monnier in
5863 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5864 * alloc.c (widen_to_Lisp_Object): New static function.
5865 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5866 and widening them to Lisp_Objects. This would work even if
5867 USE_LSB_TAG is defined and wide integers are used, which might
5868 happen in a future version of Emacs.
5870 2012-02-25 Chong Yidong <cyd@gnu.org>
5872 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

5876 (x_clipboard_manager_save_all): Print an informative message
5877 before saving to clipboard manager.
5879 2012-02-24 Chong Yidong <cyd@gnu.org>
5881 * keyboard.c (process_special_events): Handle all X selection

5884 2012-02-23 Chong Yidong <cyd@gnu.org>
5886 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5887 call when setting menu-bar-lines and tool-bar-lines parameters.
5888 (unwind_create_frame_1): New helper function.
5890 * window.c (inhibit_window_configuration_change_hook): New var.
5891 (run_window_configuration_change_hook): Obey it.
5892 (syms_of_window): Initialize it.
5894 2012-02-22 Chong Yidong <cyd@gnu.org>
5896 * xterm.c (x_draw_image_relief): Add missing type check for

5909 when computing $valmask.
5911 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5912 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5913 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5914 It's useless in that case, and it can cause problems on hosts
5915 that allocate halves of EMACS_INT values separately.
5916 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5917 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5918 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5919 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5920 it avoids undefined behavior on hosts where shifting right by more
5921 than the word width has undefined behavior.
5923 2012-02-19 Chong Yidong <cyd@gnu.org>
5925 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5926 (Funhandled_file_name_directory, Ffile_name_as_directory)
5927 (Fdirectory_file_name, Fexpand_file_name)

5945 2012-02-15 Chong Yidong <cyd@gnu.org>
5947 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5948 marked as special. Also, starting docstrings with * is obsolete.
5950 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

5963 2012-02-12 Chong Yidong <cyd@gnu.org>
5965 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5966 as that creates a dangerous corner case.
5968 * window.c (Fdelete_window_internal): Invalidate the mouse
5969 highlight (Bug#9904).
5971 2012-02-12 Glenn Morris <rgm@gnu.org>

5976 * nsselect.m (Fx_own_selection_internal)
5977 (Fx_disown_selection_internal, Fx_selection_exists_p)
5978 (Fx_selection_owner_p, Fx_get_selection_internal):
5979 Sync docs and argument specs with the xselect.c versions.

6001 2012-02-07 Chong Yidong <cyd@gnu.org>
6003 * buffer.c (Fbuffer_local_variables)
6004 (buffer_lisp_local_variables): Handle unbound vars correctly;
6005 don't let Qunbound leak into Lisp.
6007 2012-02-07 Glenn Morris <rgm@gnu.org>
6009 * image.c (Fimagemagick_types): Doc fix.
6011 * image.c (imagemagick-render-type): Change it from a lisp object

6017 * doc.c (store_function_docstring): Avoid applying docstring of
6018 alias to base function (Bug#2603).

6044 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
6046 Handle overflow when computing char display width (Bug#9496).
6047 * character.c (char_width): Return EMACS_INT, not int.
6048 (char_width, c_string_width): Check for overflow when
6049 computing the width; this is possible now that individual
6050 characters can have unbounded width. Problem introduced
6051 by merge from Emacs 23 on 2012-01-19.
6053 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

6082 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
6083 first 2 arguments are identical. This makes inserting large
6084 output from a subprocess an order of magnitude faster on
6085 MS-Windows, where all sbrk'ed memory is always contiguous.

6191 emacs: fix an auto-save permissions race condition (Bug#10400)
6192 * fileio.c (auto_saving_dir_umask): New static var.
6193 (Fmake_directory_internal): Use it.
6194 (do_auto_save_make_dir): Set it, instead of invoking chmod after
6195 creating the directory. The old code temporarily assigns
6196 too-generous permissions to the directory.
6197 (do_auto_save_eh): Clear it.
6198 (Fdo_auto_save): Catch all errors, not just file errors, so
6199 that the var is always cleared.

6256 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
6257 property that ends at ZV, so that the bidi iteration could be

6705 is set, removing the need for VIRT_ADDRESS_VARIES.

6723 behave as if the cursor position were at the window margin.
6725 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6726 and the cursor position is out of bounds, behave as if the cursor
6727 position were at the window margin. (Bug#10075)

6757 * dispnew.c (verify_row_hash): Call row_hash for computing the
6758 hash code of a row, instead of duplicating code from xdisp.c.
6760 * dispextern.h (row_hash): Add prototype.
6762 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

6868 The trivial performance wins aren't worth the portability hassles; see
6869 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6871 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6950 * intervals.c (adjust_intervals_for_insertion)
6951 (adjust_intervals_for_deletion): Now extern, because otherwise the
6952 extern inline functions 'offset_intervals' couldn't refer to it.
6953 (static_offset_intervals): Remove.
6954 (offset_intervals): Rewrite using the old contents of
6955 static_offset_intervals. The old version didn't conform to C99
6956 because an extern inline function contained a reference to an

6979 (Fwindow_vscroll): Doc fix.
6980 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6981 argument, since it makes no sense to pass a live window and for

7249 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7251 * sysdep.c (init_sys_modes): Fix the check for the controlling
7252 terminal (Bug#6649).
7254 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7256 * dispextern.h (struct bidi_it): New member next_en_type.
7258 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7259 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7260 current character, check also for next_en_type being WEAK_EN.
7261 (bidi_resolve_weak): Don't enter the expensive loop if the current
7262 position is before next_en_pos. Record the bidi type of the first
7263 non-ET, non-BN character we find, in addition to its position.
7264 (bidi_level_of_next_char): Invalidate next_en_type when
7265 next_en_pos is over-stepped.
7267 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7269 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7270 * editfns.c: Rewrite current-time-zone so that it invokes
7271 the equivalent of (format-time-string "%Z") to get the time zone name.
7272 This fixes a bug when the time zone name contains characters that
7273 need converting from the system time locale to Emacs internal format.
7274 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7275 that patch fixed format-time-string to do the conversion, but
7276 I forgot to fix current-time-zone.
7277 (format_time_string): New function, containing most of
7278 what Fformat_time_string used to contain.
7279 (Fformat_time_string): Rewrite in terms of format_time_string.
7280 This doesn't change this function's behavior.
7281 (current-time-zone): Rewrite to use format_time_string.
7282 This fixes the bug reported by Michael Schierl in
7283 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7284 Jason Rumney's 2007-06-07 change worked around this bug, but
7286 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7288 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7290 * xdisp.c (start_display): If the character at POS is displayed
7291 via a display vector, reset IT->current.dpvec_index to zero.
7292 (try_window_reusing_current_matrix): If a line ends in a display
7293 vector or the next line starts in a display vector, continue
7294 redrawing the window even though the character position of
7295 start_row was reached.
7298 2011-10-18 Chong Yidong <cyd@gnu.org>
7300 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7301 with nobreak-char-display too.
7303 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7305 Fix part 3 of bug#9771.
7306 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7307 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7308 non-neutral characters if the current character is a paragraph
7309 separator (a.k.a. Newline). This avoids running the same
7310 expensive loop twice, once when we consume the preceding newline
7311 and the other time when the line actually needs to be displayed.
7312 Avoid the loop when we see neutrals on the base embedding level
7313 following a character whose directionality is the same as the
7314 paragraph's. This avoids running the expensive loop when a line
7315 ends in a long sequence of neutrals, like control characters.
7316 Add assertion against STRONG_AL type. Slightly rearrange code
7317 that determines the type of a neutral given the first non-neutral
7319 (bidi_level_of_next_char): Set next_en_pos to zero when
7320 invalidating its info.
7322 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7324 * xdisp.c (push_display_prop): Determine whether to record string
7325 or buffer position by IT->string, not by IT->method. Allow
7326 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7327 (move_it_vertically_backward): Don't look for character position
7328 immediately after the newline when in a continuation line.
7331 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7333 * window.c (coordinates_in_window): Rewrite and delabelize
7334 vertical border check. (Bug#5357) (Bug#9618)
7336 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7338 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7339 errors in XSetWindowBorder (bug#9310).
7341 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7343 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7344 avoid crash when xmalloc overrun checking is enabled.
7346 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7348 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7349 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7350 cursor motion with <left> and <right> arrow keys.
7352 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7353 some callers set that themselves.
7355 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7357 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7358 display string and the previous row comes from the same string and
7359 is empty. (Bug#9739) (Bug#9738)
7361 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7363 * doc.c (get_doc_string): Encode file name (bug#9735).
7365 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7367 * bidi.c (bidi_level_of_next_char):
7368 * xdisp.c (get_visually_first_element): Remove old incorrect
7369 comments regarding the Unicode Line Separator character.
7371 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7373 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7375 * alloc.c (Fgc_status): Do not access beyond zombies array
7376 boundary if nzombies > MAX_ZOMBIES.
7377 * alloc.c (dump_zombies): Add missing format specifier.
7379 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7381 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7382 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7384 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7385 Some packages use them to denote characters with modifiers.
7387 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7389 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7390 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7391 matching a pp-number. Rename parameter var to var1.
7393 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7395 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7397 2011-10-08 Glenn Morris <rgm@gnu.org>
7399 * callint.c (Fcall_interactively): Give a more explicit error for the
7400 'c' case with a non-character input. (Bug#8479)
7402 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7404 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7406 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7407 lines that are hscrolled on the left.
7409 * dispnew.c (buffer_posn_from_coords): Account for a possible
7410 presence of header-line. (Bug#4426)
7412 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7414 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7415 Don't advertise functionality which we discourage or doesn't work.
7417 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7419 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7420 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7421 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7422 this makes Emacs dump core during garbage collection on rare
7423 occasions. sizeof is obviously inferior to offsetof here, so
7424 stick with offsetof.
7425 (GC_POINTER_ALIGNMENT): New macro.
7426 (mark_memory): Omit 3rd (offset) arg; caller changed.
7427 Don't assume EMACS_INT alignment is the same as pointer alignment.
7429 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7431 * keyboard.c (read_key_sequence_remapped): New var.
7432 (read_key_sequence): Compute remapping in the right buffer.
7433 (command_loop_1): Use read_key_sequence's remapping directly.
7435 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7437 * dired.c (file_name_completion): Don't expand file name.
7438 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7439 before checking file name handler.
7441 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7442 they've been requested explicitly (bug#9591).
7444 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7446 * keymap.c (Fsingle_key_description): Use make_specified_string
7447 instead of build_string to build string from push_key_description.
7450 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7452 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7453 This fixes a Y2038 bug on 64-bit hosts.
7454 * buffer.c (reset_buffer):
7455 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7456 (Fclear_buffer_auto_save_failure):
7457 Use 0, not -1, to represent an unset failure time, since time_t
7458 might not be signed.
7460 Remove dependency on glibc malloc internals.
7461 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7462 Move back here from lisp.h, but with their new implementations.
7463 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7464 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7465 * charset.c (charset_table_init): New static var.
7466 (syms_of_charset): Use it instead of xmalloc. This removes a
7467 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7468 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7469 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7470 Move back to alloc.c.
7471 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7472 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7474 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7476 * nsterm.m (windowDidResize): Call x_set_window_size only when
7477 ns_in_resize is true. Otherwise set pixelwidth/height and
7478 call change_frame_size (Bug#9628).
7480 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7482 Port --enable-checking=all to Fedora 14 x86-64.
7483 * charset.c (syms_of_charset): Also account for glibc malloc's
7484 internal overhead when calculating the initial malloc maximum.
7486 Port --enable-checking=all to Fedora 14 x86.
7487 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7489 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7490 (overrun_check_realloc, overrun_check_free):
7491 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7492 That way, xmalloc returns a properly-aligned pointer even if
7493 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7494 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7495 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7496 into account when calculating the initial malloc maximum.
7497 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7498 Move here from alloc.c, so that charset.c can use it too.
7499 Properly align; the old code wasn't right for common 32-bit hosts
7500 when configured with --enable-checking=all.
7501 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7502 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7504 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7506 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7509 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7511 * xdisp.c (compute_display_string_end): If there's no display
7512 string at CHARPOS, return -1.
7514 * bidi.c (bidi_fetch_char): When compute_display_string_end
7515 returns a negative value, treat the character as a normal
7516 character not covered by a display string. (Bug#9624)
7518 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7520 * lread.c (Fread_from_string): Fix typo in docstring.
7522 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7524 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7525 newline, reseat the iterator instead of bidi-iterating there one
7526 character at a time. (Bug#9610)
7527 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7528 TO_CHARPOS if the bidi iterator is at base embedding level.
7530 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7532 * lread.c (readevalloop): Use correct code for NBSP.
7533 (read1): Likewise. (Bug#9608)
7535 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7537 * dbusbind.c (Fdbus_register_signal): When service is not
7538 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7540 2011-09-25 Glenn Morris <rgm@gnu.org>
7542 * buffer.c (truncate-lines): Doc fix.
7544 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7546 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7547 (Fset_window_next_buffers): Doc fix.
7549 2011-09-24 Glenn Morris <rgm@gnu.org>
7551 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7553 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7555 Fix minor problems found by static checking.
7556 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7557 * indent.c (Fvertical_motion): Fix == vs = typo.
7559 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7561 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7562 Default value is now t. Doc fix.
7564 * indent.c (Fvertical_motion): Compute and apply the overshoot
7565 logic when moving up, not only when moving down. Fix the
7566 confusing name and values of the it_overshoot_expected variable;
7567 logic changes accordingly. (Bug#9254) (Bug#9549)
7569 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7570 CHARPOS is covered by a display string which includes newlines.
7571 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7572 is covered by a display string with embedded newlines.
7574 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7576 * dbusbind.c (Fdbus_register_signal): Add match rule to
7577 Vdbus_registered_objects_table. (Bug#9581)
7578 (Fdbus_register_method, Vdbus_registered_objects_table):
7581 2011-09-24 Jim Meyering <meyering@redhat.com>
7583 do not ignore write error for any output size
7584 The previous change was incomplete.
7585 While it makes emacs --batch detect the vast majority of stdout
7586 write failures, errors were still ignored whenever the output size is
7587 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7588 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7589 && echo FAIL: ignored write error
7590 FAIL: ignored write error
7591 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7592 && echo FAIL: ignored write error
7593 FAIL: ignored write error
7594 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7596 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7598 * emacs.c (Fkill_emacs): In noninteractive mode exit
7599 non-successfully if a write error occurred on stdout. (Bug#9574)
7601 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7603 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7606 * dispextern.h (struct it): Update the comment documenting what
7609 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7611 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7612 a display string, extend search for cursor position to end of row.
7613 (find_row_edges): If the row ends in a newline from a display
7614 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7615 Handle the case of a display string with multiple newlines.
7616 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7617 non-empty line. Fixes confusing cursor motion with arrow keys at
7618 the beginning of a line that starts with whitespace.
7620 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7622 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7625 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7627 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7630 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7632 * xdisp.c (display_line): Record maximum and minimum buffer
7633 positions even if no glyphs were produced (e.g., by a zero-width
7634 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7635 buffer positions that will be removed from the glyph row because
7637 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7638 column is beyond frame width: don't subtract 1 "pixel" when
7639 computing width of the stretch.
7640 (reseat_at_next_visible_line_start): Undo the change made on
7641 2011-09-17 that saved paragraph information and restored it after
7642 the call to `reseat'. (Bug#9545)
7644 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7646 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7647 and turn window cursor on if cleared (Bug#9415).
7649 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7651 * search.c (boyer_moore): Take unibyte characters from pattern
7652 literally. (Bug#9458)
7654 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7656 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7658 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7660 Fix minor problem found by static checking.
7661 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7662 initialized, to pacify gcc -Wuninitialized.
7664 * fileio.c: Report proper errno when syscall falls.
7665 (Finsert_file_contents): Save and restore errno,
7666 so that report_file_error outputs the correct diagnostic.
7667 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7669 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7671 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7673 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7675 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7676 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7678 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7680 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7681 about the current paragraph and restore it after the call to reseat.
7683 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7684 (bidi_find_paragraph_start): Search back for paragraph beginning
7685 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7686 (bidi_move_to_visually_next): Only trigger paragraph-related
7687 computations when the last character is a newline or at EOB, not
7688 just any NEUTRAL_B. (Bug#9470)
7690 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7691 truncated lines if point is covered by a display string. (Bug#9524)
7693 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7695 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7696 (cons_to_x_long): New function.
7697 (lisp_data_to_selection_data): Use it. Correct the test for
7698 short-versus-long data; it was negated. Break out of vector
7699 loop, for efficiency, when a long datum is discovered.
7701 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7703 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7705 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7707 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7708 GCC PR/17406) by declaring this function with external scope.
7710 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

7717 * editfns.c (Fformat): Correctly handle text properties on "%%".
7719 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7721 * xterm.c (x_draw_composite_glyph_string_foreground):
7722 * w32term.c (x_draw_composite_glyph_string_foreground):
7723 * term.c (encode_terminal_code):
7724 * composite.c (composition_update_it, get_composition_id):
7725 * xdisp.c (get_next_display_element)
7726 (fill_composite_glyph_string): Add comments about special meaning
7727 of TAB characters in a composition.
7729 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7731 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7732 This occurs when processing a multibyte format.
7733 Problem reported by Wolfgang Jenker.
7735 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7737 * xdisp.c (try_cursor_movement): Only check for exact match if
7738 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7740 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7742 Remove unused external symbols.
7743 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7744 * xdisp.c (calc_pixel_width_or_height): Now static.
7745 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7746 * indent.c (check_display_width):
7747 * w32term.c: Fix comment to match code.
7748 * xterm.c, xterm.h (x_catching_errors): Remove.
7750 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7752 * xselect.c: Use signed conversions more consistently (Bug#9498).
7753 (selection_data_to_lisp_data): Assume incoming selection data are
7754 signed integers, not unsigned. This is to be consistent with
7755 outgoing selection data, which was modified to use signed integers
7756 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7757 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7758 expects long, not unsigned long.
7760 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7762 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7763 computation of loop end. Reported by Johan Bockgård
7766 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7768 * frame.c (Fother_visible_frames_p): Function deleted.
7770 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7772 * indent.c (compute_motion): Process display vector front to back
7773 rather than the other way around. (Bug#2496)
7775 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7777 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7779 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7781 * minibuf.c (Fread_from_minibuffer): Doc fix.
7783 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7785 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7786 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7788 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7790 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7791 value for non-existent files.
7793 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7795 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7796 set its "size" to -1. This will set the modtime_size field of
7797 the corresponding buffer to -1, which is what
7798 verify-visited-file-modtime expects for files that do not exist.
7801 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7803 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7805 * lisp.h: ... from here. push_key_description is no longer
7806 defined in keyboard.c, so its declaration should not be in
7807 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7808 logically belongs with push_key_description.
7810 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7812 * buffer.h: Include <sys/types.h> instead of <time.h>.
7813 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7814 Problem reported by Herbert J. Skuhra.
7816 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7818 * xml.c (parse_region): Make the parsing work for
7819 non-comment-starting XML files again (bug#9144).
7821 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7823 * image.c (gif_load): Fix calculation of bottom and right corner.
7826 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7828 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7829 redisplay in small windows.
7831 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7833 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7835 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7837 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7838 Operate on live windows only.
7840 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7842 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7844 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7846 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7847 only under bidi iteration.
7849 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7851 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7853 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7855 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7856 Without this fix, the command to link temacs failed due to an
7857 undefined symbol __builtin_isnan. This is because
7858 /usr/include/iso/math_c99.h #defines isnan(x) to
7859 __builtin_isnan(x), but the bundled gcc, which identifies itself
7860 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7862 * floatfns.c (isnan): #undef, and then #define to a clone of
7864 (Fisnan): Always define, since it's always available now.
7865 (syms_of_floatfns): Always define isnan at the Lisp level.
7867 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7869 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7871 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7873 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7874 The previous code assumed that file offsets (off_t values) fit in
7875 EMACS_INT variables, which is not true on typical 32-bit hosts.
7876 The code messed up by falsely reporting buffer overflow in cases
7877 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7878 when "big" contains more than 2**29 bytes, even though this
7879 inserts just one byte and does not overflow the buffer.
7880 (Finsert_file_contents): Store file offsets as off_t
7881 values, not as EMACS_INT values. Check for overflow when
7882 converting between EMACS_INT and off_t. When checking for
7883 buffer overflow or for overlap, take the offsets into account.
7884 Don't use EMACS_INT for small values where int suffices.
7885 When checking for overlap, fix a typo: ZV was used where
7886 ZV_BYTE was intended.
7887 (Fwrite_region): Don't assume off_t fits into 'long'.
7888 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7890 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7892 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7894 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7896 sprintf-related integer and memory overflow issues (Bug#9412).
7898 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7899 (esprintf, exprintf, evxprintf): New functions.
7900 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7901 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7902 (modify_event_symbol): Do not assume that the length of
7903 name_alist_or_stem is safe to alloca and fits in int.
7904 (Fexecute_extended_command): Likewise for function name and binding.
7905 (Frecursion_depth): Wrap around reliably on integer overflow.
7906 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7907 since some callers pass EMACS_INT values.
7908 (Fsingle_key_description): Don't crash if symbol name contains more
7909 than MAX_ALLOCA bytes.
7910 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7911 (get_minibuffer): Arg is now EMACS_INT, not int.
7912 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7913 (esprintf, exprintf, evxprintf): New decls.
7914 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7916 * dbusbind.c (signature_cat): New function.
7917 (xd_signature, Fdbus_register_signal):
7918 Do not overrun buffer; instead, report string overflow.
7920 * dispnew.c (add_window_display_history): Don't overrun buffer.
7921 Truncate instead; this is OK since it's just a log.
7923 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7924 even if the time zone offset is outlandishly large.
7925 Don't mishandle offset == INT_MIN.
7927 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7928 when creating daemon; the previous buffer-overflow check was incorrect.
7930 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7931 which has the guts of the old verror function.
7933 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7934 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7936 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7937 (font_unparse_xlfd): Don't blindly alloca long strings.
7938 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7939 fits in int, when using sprintf. Use single snprintf to count
7940 length of string rather than counting it via multiple sprintfs;
7941 that's simpler and more reliable.
7942 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7943 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7944 sprintf, in case result does not fit in int.
7946 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7947 (fontset_from_font): Print it.
7949 * frame.c (tty_frame_count): Now printmax_t, not int.
7950 (make_terminal_frame, set_term_frame_name): Print it.
7951 (x_report_frame_params): In X, window IDs are unsigned long,
7952 not signed long, so print them as unsigned.
7953 (validate_x_resource_name): Check for implausibly long names,
7954 and don't assume name length fits in 'int'.
7955 (x_get_resource_string): Don't blindly alloca invocation name;
7956 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7959 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7960 (xg_check_special_colors, xg_set_geometry):
7961 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7963 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7964 Use esprintf, not sprintf, in case result does not fit in int.
7966 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7967 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7968 it as a large positive number.
7969 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7970 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7972 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7973 in case result does not fit in int.
7975 * print.c (float_to_string): Detect width overflow more reliably.
7976 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7977 buffer overrun. Don't assume list length fits in 'int'. Treat
7978 print length of 0 as 0, not as infinity; to be consistent with other
7979 uses of print length in this function. Don't overflow print length
7980 index. Don't assume hash table size fits in 'long', or that
7981 vectorlike size fits in 'unsigned long'.
7983 * process.c (make_process): Use printmax_t, not int, to format
7984 process-name gensyms.
7986 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7988 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7989 to avoid potential buffer overrun.
7991 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7992 if X resource line is longer than 512 bytes.
7994 * xfns.c (x_window): Make sprintf buffer a bit bigger
7995 to avoid potential buffer overrun.
7997 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7999 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8001 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8003 Integer overflow fixes for scrolling, etc.
8004 Without these, Emacs silently mishandles large integers sometimes.
8005 For example, "C-u 4294967297 M-x recenter" was treated as if
8006 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8008 * xdisp.c (try_window_id): Check Emacs fixnum range before
8009 converting to 'int'.
8011 * window.c (window_scroll_line_based, Frecenter):
8012 Check that an Emacs fixnum is in range before assigning it to 'int'.
8013 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8014 values converted from Emacs fixnums.
8015 (Frecenter): Don't wrap around a line count if it is out of 'int'
8016 range; instead, treat it as an extreme value.
8017 (Fset_window_configuration, compare_window_configurations):
8018 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8020 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8021 that can exceed INT_MAX. Check that EMACS_INT value is in range
8022 before assigning it to the (possibly-narrower) index.
8023 (match_limit): Don't assume that a fixnum can fit in 'int'.
8025 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8028 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8029 (Fvertical_motion): Don't wrap around LINES values that don't fit
8030 in 'int'. Instead, treat them as extreme values. This is good
8031 enough for windows, which can't have more than INT_MAX lines anyway.
8033 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8035 * Require libxml/parser.h to avoid compilation warning.
8037 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8039 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8040 since this reportedly can destroy thread storage.
8042 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8044 * syntax.c (find_defun_start): Update all cache variables if
8045 exiting early (Bug#9401).
8047 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8049 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8051 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8052 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8053 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8055 * term.c (tty_append_glyph): New function.
8056 (produce_stretch_glyph): Static function and its prototype deleted.
8058 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8061 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8063 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8064 when checking :margin (Bug#9390).
8065 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8066 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8067 so that the name doesn't mislead. All uses changed.
8069 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8071 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8074 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8076 * xdisp.c (move_it_to): Don't bail out early when reaching
8077 position beyond to_charpos, if we are scanning backwards.
8078 (move_it_vertically_backward): When DY == 0, make sure we get to
8079 the first character in the line after the newline.
8081 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8083 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8084 (ccl_driver): Do not generate an out-of-range pointer.
8085 (Fccl_execute_on_string): Remove unnecessary check for
8086 integer overflow, noted by Stefan Monnier in
8087 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8088 Remove a FIXME that didn't need fixing.
8089 Simplify the newly-introduced buffer reallocation code.
8091 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8093 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8095 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8097 Integer and memory overflow issues (Bug#9196).
8099 * doc.c (get_doc_string): Rework so that
8100 get_doc_string_buffer_size is the actual buffer size, rather than
8101 being 1 less than the actual buffer size; this makes xpalloc more
8104 * image.c (x_allocate_bitmap_record, cache_image):
8105 * xselect.c (Fx_register_dnd_atom):
8106 Simplify previous changes by using xpalloc.
8108 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8109 since either will do and ptrdiff_t is convenient with xpalloc.
8111 * charset.c (charset_table_size)
8112 (struct charset_sort_data.priority): Now ptrdiff_t.
8113 (charset_compare): Don't overflow if priorities differ greatly.
8114 (Fsort_charsets): Don't assume list length fits in int.
8115 Check for size-calculation overflow when allocating sort data.
8116 (syms_of_charset): Allocate an initial charset table that is
8117 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8119 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8121 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8122 The actual value is always <= INT_MAX, and leaving it unsigned made
8123 overflow checking harder.
8125 * dispextern.h (struct glyph_matrix.rows_allocated)
8126 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8127 with xpalloc. The values are still always <= INT_MAX.
8129 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8131 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8132 (SAFE_NALLOCA): New macro.
8134 * region-cache.c (struct boundary.pos, find_cache_boundary)
8135 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8136 (set_cache_region, invalidate_region_cache)
8137 (revalidate_region_cache, know_region_cache, region_cache_forward)
8138 (region_cache_backward, pp_cache):
8139 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8140 so that ptrdiff_t * can be passed to xpalloc.
8141 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8142 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8143 (pp_cache): Don't assume cache_len fits in int.
8144 * region-cache.h: Adjust extern decls to match.
8146 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8147 EMACS_INT, since either will do, for xpalloc.
8149 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8150 (xnmalloc, xnrealloc, xpalloc): New functions.
8152 * bidi.c (bidi_shelve_header_size): New constant.
8153 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8154 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8156 * bidi.c (bidi_cache_shrink):
8157 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8159 Don't update size of array until after memory allocation succeeds,
8160 because xmalloc/xrealloc may not return.
8161 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8162 now that we have proper integer overflow checking.
8163 (record_overlay_string, overlay_strings): Catch overflows when
8164 calculating size of overlay_str_buf.
8166 * callproc.c (Fcall_process): Check for size overflow when
8167 calculating size of args2.
8168 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8169 Normally we prefer signed values, but sticking with ptrdiff_t would
8170 require adding more-complicated checks.
8172 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8173 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8174 Redo buffer-overflow calculations to avoid integer overflow.
8175 Add a FIXME comment where memory seems to be over-allocated.
8177 * character.c (Fstring): Check for size-calculation overflow.
8179 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8180 unnecessary integer overflow. Check for size overflow.
8181 (encode_coding_object): Don't update size until xmalloc succeeds.
8183 * composite.c (get_composition_id): Check for overflow in glyph
8184 length calculations.
8186 Integer and memory overflow fixes for display code.
8187 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8188 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8189 (scrolling_window): Check for overflow in size calculations.

8213 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8215 * emacs.c (main): Do not reallocate argv, since there is a null at
8216 the end that can be overwritten, and this way there's no need to
8217 worry about size-calculation overflow.
8218 (sort_args): Check for size-calculation overflow.
8220 * eval.c (init_eval_once, grow_specpdl): Don't update size until

8231 where the system imposes an 'int' limit.
8233 * fringe.c (Fdefine_fringe_bitmap):
8234 Don't update size until alloc works.

8347 (X_LONG_MIN): New macros.
8348 Use them to make the following changes clearer.
8349 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

8351 future maintainers not to raise the value too much later.
8352 (SELECTION_QUANTUM): Remove, replacing with ...
8353 (selection_quantum): ... new function, which avoids overflow.
8355 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

8373 Don't store size until memory allocation succeeds.
8374 (x_get_window_property): Plug memory leak on memory exhaustion.
8375 Don't double-block input; malloc is safe here. Don't assume 2**34
8376 - 4 fits in unsigned long. Add an xassert to check
8377 XGetWindowProperty overflow. Be more careful about overflow
8378 calculations, and distinguish size from memory overflow better.

8384 in the range -65535 through -1 fit in an X unsigned short.
8385 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8386 result parameters unless successful. Rely on cons_to_unsigned
8387 to report problems with elements; the old code wasn't right anyway.
8388 (x_check_property_data): Check for int overflow; we cannot use
8389 a wider type due to X limits.

8422 * lisp.h (hash_lookup, hash_put):
8423 * minibuf.c (Ftest_completion):
8424 Use ptrdiff_t for hash table indexes, not int (which is too
8425 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

8459 (x_send_scroll_bar_event): Likewise. Check that the size does not
8460 exceed limits imposed by XClientMessageEvent, as well as the usual
8461 ptrdiff_t and size_t limits.
8463 * keyboard.c: Overflow, signedness and related fixes.
8464 (make_lispy_movement): Use same integer type in forward decl
8465 that is used in the definition.
8466 (read_key_sequence, keyremap_step):
8467 Change bufsize argument back to int, undoing my 2011-03-30 change.
8468 We prefer signed types, and int is wide enough here.
8469 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8470 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow

8472 length, not size_t. Use ptrdiff_t for index, not int.

8502 Prefer int to unsigned where either will do.
8503 (tiff_handler): New function, combining the cores of the
8504 old tiff_error_handler and tiff_warning_handler.
8505 This function is rewritten to use vsnprintf and thereby avoid
8506 stack buffer overflows. It uses only the features of vsnprintf
8507 that are common to both POSIX and native Microsoft.
8508 (tiff_error_handler, tiff_warning_handler): Use it.
8509 (tiff_load, gif_load, imagemagick_load_image):

8513 the integer types that MagickCropImage accepts. Don't assume
8514 Vimagemagick_render_type has a nonnegative value. Don't assume
8515 size_t fits in 'long'.
8516 (gs_load): Use printmax_t to print the widest integers possible.

8534 accurately, and prefer exact match for point under bidi.
8535 Don't advance `row' beyond the last row of the window.
8537 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8538 into disp_prop; all users changed.
8540 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8556 positioning on the newline at EOL of R2L text within L2R
8557 paragraph, and vice versa.
8558 (try_cursor_movement): Check continued rows, in addition to
8559 continuation rows. Fixes unwarranted scroll when point enters a
8560 continued line of R2L text within an L2R paragraph, or vice versa.
8561 (cursor_row_p): Consider the case of point being equal to
8562 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8563 from the end of a short line to the beginning of a continued line
8564 of R2L text within L2R paragraph.
8565 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8588 * xdisp.c (redisplay_window): When computing centering_position,
8589 account for the height of the header line. (Bug#8874)
8591 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8592 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8593 candidate is selected by the mouse, and that candidate has a
8594 composed character under the mouse.
8596 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8597 coordinates reported by pos-visible-in-window-p for a composed

8607 consider it a hit if to_charpos is anywhere in the range of the
8608 composed buffer positions.
8610 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8612 * image.c (gif_load): Don't assume that each subimage has the same
8613 dimensions as the base image. Handle disposal method that is
8614 "undefined" by the gif spec (Bug#9335).
8616 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8618 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8621 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8623 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8624 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8625 from an Org mode buffer to a Speedbar frame.
8627 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8628 a composition, take its buffer position from IT->cmp_it.charpos.
8629 Fixes cursor positioning at the beginning of a line that begins
8630 with a composed character.
8632 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8634 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8635 character bidirectional type, use STRONG_L instead. Fixes crashes
8636 in a buffer produced by `describe-categories'.
8638 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8639 members before the level stack, so they would be saved and
8640 restored when copying iterator state. Fixes incorrect reordering
8641 around TABs covered by display properties.
8643 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8645 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
8647 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
8649 * eval.c (internal_condition_case, internal_condition_case_1)
8650 (internal_condition_case_2, internal_condition_case_n):
8651 Remove unnecessary aborts (Bug#9081).
8653 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8655 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8656 has no `load' handler, try opening the file locally. (Bug#9311)
8658 2011-08-16 Ken Brown <kbrown@cornell.edu>
8660 * gmalloc.c: Expand comment.
8662 2011-08-16 Eli Zaretskii <eliz@gnu.org>
8664 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
8665 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8667 2011-08-16 Ken Brown <kbrown@cornell.edu>
8669 Fix memory allocation problems in Cygwin build (Bug#9273).
8671 * unexcw.c ( __malloc_initialized): Declare external variable.
8672 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8674 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8676 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8678 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8680 [CYGWIN] (special_realloc): New function.
8681 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8682 requests to realloc storage in the static heap.
8684 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8686 * bidi.c (bidi_initialize): Remove unused local.
8688 2011-08-15 Eli Zaretskii <eliz@gnu.org>
8691 * biditype.h: Remove file.
8692 * makefile.w32-in ($(BLD)/bidi.$(O)):
8693 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8695 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8697 * chartab.c: Improve commentary for the uniprop_table API.
8699 * bidi.c (bidi_paragraph_init): Support zero value of
8700 bidi_ignore_explicit_marks_for_paragraph_level.
8701 (bidi_initialize): Use uniprop_table instead of including
8702 biditype.h and bidimirror.h.
8704 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8705 coordinates of the iterator when restoring from ppos_it.
8708 2011-08-14 Kenichi Handa <handa@m17n.org>
8710 * process.c (create_process): Call setup_process_coding_systems
8711 after the pid of the process is set to -1 (Bug#8162).
8713 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8715 * xdisp.c (move_it_in_display_line_to): Don't invoke
8716 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8717 ppos_it. Fixes vertical cursor motion when line beginning is
8718 covered by an image. (Bug#9296)
8720 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8722 * nsterm.h (ns_run_ascript): Declare.
8723 (NSAPP_DATA2_RUNASSCRIPT): Define.
8725 * nsfns.m (as_script, as_result, as_status): New static variables.
8726 (ns_run_ascript): New function.
8727 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8728 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8729 the event loop. Get status from as_status (Bug#7276).
8731 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8732 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8733 the event loop (Bug#7276).
8735 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8737 * gnutls.c (QCgnutls_bootprop_priority)
8738 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8739 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8740 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8741 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8742 (QCgnutls_bootprop_verify_hostname_error)
8743 (QCgnutls_bootprop_callbacks_verify): Rename from
8744 Qgnutls_bootprop_..., all uses changed.
8746 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8749 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8751 * xfaces.c (Qframe_set_background_mode): Now static.
8752 * dispextern.h (Qframe_set_background_mode): Remove decl.

8756 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8758 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8759 (Fnetwork_interface_list): Allocate in increments of bytes instead
8760 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8761 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8763 (struct ifflag_def): notrailers is smart on OSX.
8764 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8765 Get hardware address with getifaddrs if available.
8767 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8769 * xdisp.c (iterate_out_of_display_property): xassert that
8770 IT->position is set to within IT->object's boundaries. Break from
8771 the loop as soon as EOB is reached; avoids infloops in redisplay
8772 when IT->position is set up wrongly due to some bug.
8773 Set IT->current to match the bidi iterator unconditionally.
8774 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8775 entry. Force push_it to save on the stack the current
8776 buffer/string position, to be restored by pop_it. Fix flags in
8777 the iterator structure wrt the object coming from a display
8778 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8779 properties. (Bug#9284)
8781 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8783 * fontset.c (fontset_get_font_group): Add proper type checks.
8786 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

8789 and LC_VERSION_MIN_MACOSX.
8790 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8791 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8793 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8795 * xdisp.c (forward_to_next_line_start): Allow to use the
8796 no-display-properties-and-no-overlays under bidi display.
8797 Set disp_pos in the bidi iterator to avoid searches for display
8798 properties and overlays.
8800 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8802 * editfns.c (Fset_time_zone_rule): Document relationship with the
8805 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8806 the font entity extracted from the cache (Bug#8109).
8808 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8810 * composite.c (autocmp_chars): Don't reset point. That is done by
8811 restore_point_unwind (Bug#5984).
8813 2011-08-07 Juri Linkov <juri@jurta.org>
8815 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8816 to show the arg `TIME' instead of `TIMEVAL'.
8818 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8820 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8821 display property strides EOL and includes a newline, as in
8822 longlines-mode. (Bug#9254)
8823 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8824 word-wrap under bidirectional display. (Bug#9224)
8826 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8827 is non-zero, even if the data buffer is NULL. Fixes a crash in
8828 vertical-motion with longlines-mode. (Bug#9254)
8830 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8832 * bidi.c <bidi_cache_total_alloc>: Now static.
8833 (bidi_initialize): Initialize bidi_cache_total_alloc.
8835 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8838 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8839 amount allocated this far in `bidi_cache_total_alloc'.
8840 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8841 non-zero, only free the data buffer without restoring the cache
8842 contents. All callers changed.
8844 * dispextern.h (bidi_unshelve_cache): Update prototype.
8846 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8847 (move_it_in_display_line, move_it_to)
8848 (move_it_vertically_backward, move_it_by_lines): Replace the call
8849 to xfree to an equivalent call to bidi_unshelve_cache.
8850 (move_it_in_display_line_to): Fix logic of returning
8851 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8853 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8855 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8856 came from a string character with a `cursor' property. (Bug#9229)
8858 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8860 * Makefile.in (LIB_PTHREAD): New variable.
8861 (LIBES): Add LIB_PTHREAD (Bug#9216).
8863 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8864 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8866 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8868 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8870 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8872 * xterm.c (x_find_topmost_parent): New function.
8873 (x_set_frame_alpha): Find topmost parent window with
8874 x_find_topmost_parent and set the property there also (bug#9181).
8875 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8877 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8879 * callproc.c (Fcall_process): Avoid vfork clobbering
8880 the local vars buffer, coding_systems, current_dir.
8882 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8884 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8886 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8888 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8889 so that it is not optimized away.
8891 * xdisp.c (compute_display_string_pos): Remove unused local.
8893 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8895 Fix slow cursor motion and scrolling in large buffers with
8896 selective display, like Org Mode buffers. (Bug#9218)
8898 * dispextern.h (struct bidi_it): New member disp_prop_p.
8900 * xdisp.c: Remove one-slot cache of display string positions.
8901 (compute_display_string_pos): Accept an additional argument
8902 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8903 for a display string or property. If found, set DISP_PROP_P
8906 * bidi.c (bidi_fetch_char): Accept an additional argument
8907 DISP_PROP_P, and pass it to compute_display_string_pos.
8908 Only handle text covered by a display string if DISP_PROP_P is returned
8909 non-zero. All callers of bidi_fetch_char changed.
8911 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8913 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8915 2010-12-03 Don March <don@ohspite.net>
8917 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8918 last character M-[char] is translated to ESC [char] (bug#7541).
8920 2011-08-02 Kenichi Handa <handa@m17n.org>
8922 * lisp.h (uniprop_table): Extern it.
8924 * chartab.c (uniprop_table): Make it non-static.
8926 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8928 * xdisp.c (forward_to_next_line_start): Accept additional argument
8929 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8931 (reseat_at_next_visible_line_start): Use the bidi iterator state
8932 returned by forward_to_next_line_start to restore the state of
8933 it->bidi_it after backing up to previous newline. (Bug#9212)
8935 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8937 * regex.c (re_comp): Protoize.
8938 (re_exec): Fix return type.
8939 (regexec): Fix type of `ret'. (Bug#9203)
8941 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8943 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8944 This is needed if max-image-size is a floating-point number.
8946 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8948 * print.c (print_object): Print empty symbol as ##.
8950 * lread.c (read1): Read ## as empty symbol.
8952 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8954 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8955 setting frame foreground color (Bug#9175).
8956 (x_set_background_color): Likewise.
8958 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8959 contents (Bug#9176).
8960 (EmacsTooltip -init): Remove bezels and add shadows to
8963 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8964 or scroll bar (Bug#8470).
8966 * nsfont.m (nsfont_open): Remove assignment to voffset and
8967 unnecessary vars hshink, expand, hd, full_height, min_height.
8968 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8970 * nsterm.h (nsfont_info): Remove voffset field.
8972 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8974 Implement strike-through and overline on NextStep (Bug#8863).
8976 * nsfont.m (nsfont_open): Use underline position provided by font,
8977 instead of hard-coded value of 2.
8978 (nsfont_draw): Call ns_draw_text_decoration instead.
8980 * nsterm.h: Add declaration for ns_draw_text_decoration.
8982 * nsterm.m (ns_draw_text_decoration): New function for drawing
8983 underline, overline, and strike-through.
8984 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8985 ns_draw_text_decoration. Change treatment of cursor drawing to
8986 accommodate underlining, etc.
8988 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8990 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8993 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8995 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8996 Without this fix, if a signal arrives just after memory fills up,
8997 'malloc' might be invoked reentrantly.
8999 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9000 In other words, assume that every image size is allowed, on non-X
9001 hosts. This assumption is probably wrong, but it lets Emacs compile.
9003 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9005 * regex.c (re_iswctype): Convert return values to boolean.
9007 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9009 * xdisp.c (compute_display_string_pos): Don't use cached display
9010 string position if the buffer had its restriction changed.
9013 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9015 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9017 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9019 Integer signedness and overflow and related fixes. (Bug#9079)
9021 * bidi.c: Integer size and overflow fixes.
9022 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9023 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9024 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9025 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9026 (bidi_find_other_level_edge):
9027 Use ptrdiff_t instead of EMACS_INT where either will do.
9028 This works better on 32-bit hosts configured --with-wide-int.
9029 (bidi_cache_ensure_space): Check for size-calculation overflow.
9030 Use % rather than repeated addition, for better worst-case speed.
9031 Don't set bidi_cache_size until after xrealloc returns, because it
9033 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9034 (bidi_cache_ensure_space): Also check that the bidi cache size
9035 does not exceed that of the largest Lisp string or buffer. See Eli
9036 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9038 * alloc.c (__malloc_size_t): Remove.
9039 All uses replaced by size_t. See Andreas Schwab's note
9040 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9042 * image.c: Improve checking for integer overflow.
9043 (check_image_size): Assume that f is nonnull, since
9044 it is always nonnull in practice. This is one less thing to
9045 worry about when checking for integer overflow later.
9046 (x_check_image_size): New function, which checks for integer
9047 overflow issues inside X.
9048 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9049 This removes the need for a memory_full check.
9050 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9051 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9052 (xbm_read_bitmap_data): Change locals back to 'int', since
9053 their values must fit in 'int'.
9054 (xpm_load_image, png_load, tiff_load):
9055 Invoke x_create_x_image_and_pixmap earlier,
9056 to avoid much needless work if the image is too large.
9057 (tiff_load): Treat overly large images as if
9058 x_create_x_image_and_pixmap failed, not as malloc failures.
9059 (gs_load): Use x_check_image_size.
9061 * gtkutil.c: Omit integer casts.
9062 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9063 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9065 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9067 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9068 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9069 would wrongly return t on a 64-bit host.
9071 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9072 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9073 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9074 and therefore cause GCC to emit a bogus diagnostic in some cases.
9076 * image.c: Integer signedness and overflow and related fixes.
9077 This is not an exhaustive set of fixes, but it's time to
9078 record what I've got.
9079 (lookup_pixel_color, check_image_size): Remove redundant decls.
9080 (check_image_size): Don't assume that arbitrary EMACS_INT values
9081 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9082 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9083 (tiff_load, imagemagick_load_image):
9084 Check for overflow in size calculations.
9085 (x_create_x_image_and_pixmap): Remove unnecessary test for
9086 xmalloc returning NULL; that can't happen.
9087 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9088 (xpm_color_bucket): Use better integer hashing function.
9089 (xpm_cache_color): Don't possibly over-allocate memory.
9090 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9091 (gif_memory_source):
9092 Use ptrdiff_t, not int or size_t, to record sizes.
9093 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9094 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9095 either works, as we prefer signed integers.
9096 (tiff_read_from_memory, tiff_write_from_memory):
9097 Return tsize_t, not size_t, since that's what the TIFF API wants.
9098 (tiff_read_from_memory): Don't fail simply because the read would
9099 go past EOF; instead, return a short read.
9100 (tiff_load): Omit no-longer-needed casts.
9101 (Fimagemagick_types): Don't assume size fits into 'int'.
9103 Improve hashing quality when configured --with-wide-int.
9104 * fns.c (hash_string): New function, taken from sxhash_string.
9105 Do not discard information about ASCII character case; this
9106 discarding is no longer needed.
9107 (sxhash-string): Use it. Change sig to match it. Caller changed.
9108 * lisp.h: Declare it.
9109 * lread.c (hash_string): Remove, since we now use fns.c's version.
9110 The fns.c version returns a wider integer if --with-wide-int is
9111 specified, so this should help the quality of the hashing a bit.
9113 * emacs.c: Integer overflow minor fix.
9114 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9115 Define only if GNU_LINUX.
9116 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9118 * dispnew.c: Integer signedness and overflow fixes.
9119 Remove unnecessary forward decls, that were a maintenance hassle.
9120 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9122 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9123 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9124 (prepare_desired_row, line_draw_cost):
9125 Use int, not unsigned, where either works.
9126 (save_current_matrix, restore_current_matrix):
9127 Use ptrdiff_t, not size_t, where either works.
9128 (init_display): Check for overflow more accurately, and without
9129 relying on undefined behavior.
9131 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9132 Remove, replacing with the new symbols in lisp.h. All uses changed.
9133 * fileio.c (make_temp_name):
9134 * filelock.c (lock_file_1, lock_file):
9135 * xdisp.c (message_dolog):
9136 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9137 Use pMd etc. instead.
9138 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9139 replacing the pWIDE etc. symbols removed from editfns.c.
9141 * keyboard.h (num_input_events): Now uintmax_t.
9142 This is (very slightly) less likely to mess up due to wraparound.
9145 * buffer.c: Integer signedness fixes.
9146 (alloc_buffer_text, enlarge_buffer_text):
9147 Use ptrdiff_t rather than size_t when either will do, as we prefer
9150 * alloc.c: Integer signedness and overflow fixes.
9151 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9152 (__malloc_size_t): Default to size_t, not to int.
9153 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9154 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9155 Prefer ptrdiff_t to size_t when either would do, as we prefer
9157 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9158 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9159 Now const. Initialize with values that are in range even if char
9161 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9162 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9163 These functions do the right thing with sizes > 2**32.
9164 (check_depth): Now ptrdiff_t, not int.
9165 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9166 Adjust to new way of storing sizes. Check for size overflow bugs
9168 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9169 slightly wrong anyway, as it missed one instance of
9170 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9171 (refill_memory_reserve): Omit needless cast to size_t.
9172 (mark_object_loop_halt): Mark as externally visible.
9174 * xselect.c: Integer signedness and overflow fixes.
9175 (Fx_register_dnd_atom, x_handle_dnd_message):
9176 Use ptrdiff_t, not size_t, since we prefer signed.
9177 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9178 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9179 x_dnd_atoms_size and x_dnd_atoms_length.
9181 * doprnt.c: Prefer signed to unsigned when either works.
9183 * doprnt.c (doprnt):
9185 * xdisp.c (vmessage):
9186 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9187 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9188 prefer signed arithmetic to avoid comparison confusion.
9189 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9190 but is a bit tricky.
9192 Assume freestanding C89 headers, string.h, stdlib.h.
9193 * data.c, doprnt.c, floatfns.c, print.c:
9194 Include float.h unconditionally.
9195 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9196 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9197 * regex.c: Likewise for stddef.h, string.h.
9198 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9199 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9200 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9201 (STDC_HEADERS): Remove obsolete defines.
9202 * sysdep.c: Include limits.h unconditionally.
9204 Assume support for memcmp, memcpy, memmove, memset.
9205 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9206 * regex.c (memcmp, memcpy):
9207 Remove; we assume C89 now.
9209 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9210 (__malloc_safe_bcopy): Remove; no longer needed.
9212 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9213 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9214 well either way, and we prefer signed to unsigned.
9216 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9218 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9219 closes the connection while we're reading (bug#9182).
9221 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9223 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9224 are specified (Bug#9168).
9226 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9228 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9229 Found by GCC static checking and --with-wide-int on a 32-bit host.
9231 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9233 * xdisp.c (compute_display_string_pos): Fix logic of caching
9234 previous display string position. Initialize cached_prev_pos to
9235 -1. Fixes slow-down at the beginning of a buffer.
9237 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9239 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9240 for attrs[LFACE_FONTSET_INDEX].
9242 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9244 * xml.c (parse_region): Remove unused local
9245 that was recently introduced.
9247 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9249 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9250 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9252 * xdisp.c (move_it_in_display_line_to): Record the best matching
9253 position for TO_CHARPOS while scanning the line, and restore it on
9254 exit if none of the characters scanned was an exact match.
9255 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9256 when exact match is impossible due to invisible text, and the
9257 lines are truncated.
9259 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9261 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9264 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9266 Fix a significant slow-down of cursor motion with C-n, C-p,
9267 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9268 auto-repeat under bidi redisplay in fontified buffers.
9269 * xdisp.c (compute_stop_pos_backwards): New function.
9270 (next_element_from_buffer): Call compute_stop_pos_backwards to
9271 find a suitable prev_stop when we find ourselves before
9273 (reseat): Don't look for prev_stop, as that could mean a very long
9275 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9276 <cached_disp_overlay_modiff>: Cache for last found display string
9278 (compute_display_string_pos): Return the cached position if asked
9279 about the same buffer in the same area of character positions, and
9280 the buffer wasn't changed since the time the display string
9281 position was cached.
9283 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9285 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9286 is an integer, which is important for empty lines. (Bug#9149)
9288 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9290 * frame.c (Fmodify_frame_parameters): In tty case, update the
9291 default face if necessary (Bug#4238).
9293 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9295 * editfns.c (Fstring_to_char): No need to explain what a character
9296 is in the docstring (Bug#6576).
9298 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9300 * xml.c (parse_region): Make sure we always return a tree.
9302 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9304 * xml.c (parse_region): If a document contains only comments,
9307 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9309 * xml.c (make_dom): Return comments, too.
9311 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9314 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9315 and the surrounding thread.
9316 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9317 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9318 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9320 * s/openbsd.h (BROKEN_SIGIO): Define.
9321 * unexelf.c (unexec) [__OpenBSD__]:
9322 Don't update the .mdebug section of the Alpha COFF symbol table.
9324 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9326 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9329 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9331 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9332 This fixes some race conditions on the permissions of any newly
9335 * alloc.c (valid_pointer_p): Use pipe, not open.
9336 This fixes some permissions issues when debugging.
9338 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9339 If fchown fails to set both uid and gid, try to set just gid,
9340 as that is sometimes allowed. Adjust the file's mode to eliminate
9341 setuid or setgid bits that are inappropriate if fchown fails.
9343 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9345 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9346 to compare Lisp_Objects.
9347 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9348 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9349 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9351 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9353 * lread.c (read_integer): Unread even EOF character.
9354 (read1): Likewise. Properly record start position of symbol.
9356 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9357 symbol character follows.
9359 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9361 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9362 This works around a problem with the previous change to Fcopy_file.
9363 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9364 and without this change, GCC might complain about discarding
9365 fchown's return value.
9367 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9369 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9371 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9373 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9375 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9377 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9378 it's used from the C level.
9380 * process.c: Use the same condition for POLL_FOR_INPUT in both
9381 keyboard.c and process.c (bug#1858).
9383 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9385 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9386 (Fgnutls_boot): Use it.
9388 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9390 * doc.c (Fsubstitute_command_keys): Revert last change.
9392 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9394 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9395 quotes the next character, and doesn't affect other longer
9396 sequences (bug#8935).
9398 * lread.c (syms_of_lread): Clarify that is isn't only
9399 `eval-buffer' and `eval-defun' that's affected by
9400 `lexical-binding' (bug#8460).
9402 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9404 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9405 bidi redisplay when a line includes both an image and is truncated.
9407 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9409 Fix minor problems found by static checking.
9410 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9411 (elsz): Now a signed constant, not a size_t var. We prefer signed
9412 types to unsigned, to avoid integer comparison confusion. Without
9413 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9414 "cannot optimize loop, the loop counter may overflow", a symptom
9416 * indent.c (Fvertical_motion): Mark locals as initialized.
9417 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9419 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9421 * search.c (Fre_search_backward): Mention `case-fold-search' in
9422 all the re_search_* functions (bug#8138).
9424 * keyboard.c (Fopen_dribble_file): Document when the file is
9427 2011-07-14 Eli Zaretskii <eliz@gnu.org>
9429 * bidi.c (bidi_dump_cached_states): Fix format of displaying
9432 Support bidi reordering of display and overlay strings.
9433 * xdisp.c (compute_display_string_pos)
9434 (compute_display_string_end): Accept additional argument STRING.
9435 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9436 (reseat_to_string): Initialize bidi_it->string.s and
9437 bidi_it->string.schars.
9438 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9439 NULL (avoids a crash in bidi_paragraph_init).
9440 Initialize itb.string.lstring.
9441 (init_iterator): Call bidi_init_it only of a valid
9442 buffer position was specified. Initialize paragraph_embedding to
9444 (reseat_to_string): Initialize the bidi iterator.
9445 (display_string): If we need to ignore text properties of
9446 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9447 original value of -1 will not work with bidi.)
9448 (compute_display_string_pos): First arg is now struct
9449 `text_pos *'; all callers changed. Support display properties on
9451 (compute_display_string_end): Support display properties on Lisp
9453 (init_iterator, reseat_1, reseat_to_string): Initialize the
9454 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9455 when iterating on a string not from display properties).
9456 (compute_display_string_pos, compute_display_string_end):
9457 Fix calculation of the object to scan. Fixes an error when using
9459 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9460 base_level_stop; instead, set base_level_stop to BEGV.
9461 Fixes crashes in vertical-motion.
9462 (next_element_from_buffer): Improve commentary for when
9463 the iterator is before prev_stop.
9464 (init_iterator): Initialize bidi_p from the default value of
9465 bidi-display-reordering, not from buffer-local value. Use the
9466 buffer-local value only if initializing for buffer iteration.
9467 (handle_invisible_prop): Support invisible properties on strings
9468 that are being bidi-reordered.
9469 (set_iterator_to_next): Support bidi reordering of C strings and
9471 (next_element_from_string): Support bidi reordering of Lisp
9473 (handle_stop_backwards): Support Lisp strings as well.
9474 (display_string): Support display of R2L glyph rows.
9475 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9476 (init_iterator): Don't initialize it->bidi_p for strings
9478 (reseat_to_string): Initialize it->bidi_p for strings here.
9479 (next_element_from_string, next_element_from_c_string)
9480 (next_element_from_buffer): Add xassert's for correspondence
9481 between IT's object being iterated and it->bidi_it.string
9483 (face_before_or_after_it_pos): Support bidi iteration.
9484 (next_element_from_c_string): Handle the case of the first string
9485 character that is not the first one in the visual order.
9486 (get_visually_first_element): New function, refactored from common
9487 parts of next_element_from_buffer, next_element_from_string, and
9488 next_element_from_c_string.
9489 (tool_bar_lines_needed, redisplay_tool_bar)
9490 (display_menu_bar): Force left-to-right direction. Add a FIXME
9491 comment for making that be controlled by a user option.
9492 (push_it, pop_it): Save and restore the state of the
9493 bidi iterator. Save and restore the bidi_p flag.
9494 (pop_it): Iterate out of display property for string iteration as
9496 (iterate_out_of_display_property): Support iteration over strings.
9497 (handle_single_display_spec): Set up it->bidi_it for iteration
9498 over a display string, and call bidi_init_it.
9499 (handle_single_display_spec, next_overlay_string)
9500 (get_overlay_strings_1, push_display_prop): Set up the bidi
9501 iterator for displaying display or overlay strings.
9502 (forward_to_next_line_start): Don't use the shortcut if
9504 (back_to_previous_visible_line_start): If handle_display_prop
9505 pushed the iterator stack, restore the internal state of the bidi
9506 iterator by calling bidi_pop_it same number of times.
9507 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9508 and we are bidi-iterating, don't decrement the iterator position;
9509 instead, set the first_elt flag in the bidi iterator, to produce
9511 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9512 (push_display_prop): xassert that we are iterating a buffer.
9513 (push_it, pop_it): Save and restore paragraph_embedding member.
9514 (handle_single_display_spec, next_overlay_string)
9515 (get_overlay_strings_1, reseat_1, reseat_to_string)
9516 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9517 correctly. Don't assume unibyte strings are not bidi-reordered.
9518 (compute_display_string_pos)
9519 (compute_display_string_end): Fix handling the case of C string.
9520 (push_it, pop_it): Save and restore from_disp_prop_p.
9521 (handle_single_display_spec, push_display_prop): Set the
9522 from_disp_prop_p flag.
9523 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
9524 (pop_it): Call iterate_out_of_display_property only if we are
9525 popping after iteration over a string that came from a display
9526 property. Fix a typo in popping stretch info. Add an assertion
9527 for verifying that the iterator position is in sync with the bidi
9529 (handle_single_display_spec, get_overlay_strings_1)
9530 (push_display_prop): Fix initialization of paragraph direction for
9531 string when that of the parent object is not yet determined.
9532 (reseat_1): Call bidi_init_it to resync the bidi
9533 iterator with IT's position. (Bug#7616)
9534 (find_row_edges): If ROW->start.pos gives position
9535 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
9536 (handle_stop, back_to_previous_visible_line_start, reseat_1):
9537 Reset the from_disp_prop_p flag.
9538 (SAVE_IT, RESTORE_IT): New macros.

9543 (try_scrolling, redisplay_window, display_line): Use them when
9544 saving a temporary copy of the iterator and restoring it back.
9545 (back_to_previous_visible_line_start, reseat_1)
9546 (init_iterator): Empty the bidi cache "stack".
9547 (move_it_in_display_line_to): If iterator ended up at
9548 EOL, but we never saw any buffer positions smaller than
9549 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9550 motion in bidi-reordered lines.
9551 (move_it_in_display_line_to): Record prev_method and prev_pos
9552 immediately before the call to set_iterator_to_next. Fixes cursor
9553 motion in bidi-reordered lines with stretch glyphs and strings
9554 displayed in margins. (Bug#8133) (Bug#8867)
9555 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9557 (pos_visible_p): Support positions in bidi-reordered lines.
9558 Save and restore bidi cache.
9560 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9561 (bidi_paragraph_info): Delete unused struct.
9562 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9563 (bidi_cache_start): New variable.
9564 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
9566 (bidi_cache_fetch_state, bidi_cache_search)
9567 (bidi_cache_find_level_change, bidi_cache_iterator_state)

9674 The old code sometimes used this field without initializing it.

9677 In theory, the old code could also have corrupted Emacs internals,
9678 though it'd be very unlikely.

9941 (clone_per_buffer_values): Don't assume that

9982 Random fixes. E.g., (random) never returned negative values.
9983 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9984 subseconds part to the entropy, as that's a bit more random.
9985 Prefer signed to unsigned, since the signedness doesn't matter and
9986 in general we prefer signed. When given a limit, use a
9987 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9988 latter isn't right if USE_2_TAGS_FOR_INTS.
9989 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9990 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10003 This is more efficient than Ffile_directory_p and avoids a minor race.

10007 * buffer.c (Foverlay_put): Say what the return value is
10010 * fileio.c (barf_or_query_if_file_exists): Check first if the file

10014 error be more correct.
10016 * fns.c (Frequire): Remove the mention of the .gz files, since

10135 * eval.c (struct backtrace): Simplify and port the data structure.
10136 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10137 signed bit field, as this assumption is not portable and it makes
10138 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10139 "char debug_on_exit : 1" as this is not portable either; instead,
10140 use the portable "unsigned int debug_on_exit : 1". Remove unused
10141 member evalargs. Remove obsolete comments about cc bombing out.

10376 on undefined behavior with wrong number of arguments.
10377 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10378 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10379 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10380 since we're not interested in debugging glyphs with old libraries.
10381 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10382 GCC 4.6.0's static checking.

10424 (x_session_initialize): Do not assume string length fits in int.
10426 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

10468 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10469 Reformulate so as not to need the command string.
10470 Invoke gzip -cd rather than gunzip, as it's more portable.
10471 (lock_info_type, lock_file_1, lock_file):
10472 Don't assume pid_t and time_t fit in unsigned long.
10473 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10474 (current_lock_owner): Prefer signed type for sizes.
10475 Use memcpy, not strncpy, where memcpy is what is really wanted.
10476 Don't assume (via atoi) that time_t and pid_t fit in int.
10477 Check for time_t and/or pid_t out of range, e.g., via a network share.
10478 Don't alloca where an auto var works fine.
10480 * fileio.c: Fix some integer overflow issues.
10481 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10482 Don't assume string length fits in int.
10483 (directory_file_name): Don't assume string length fits in long.
10484 (make_temp_name): Don't assume pid fits in int, or that its print
10485 length is less than 20.
10487 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10489 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10491 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10493 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10494 We prefer signed integers, even for size calculations.
10496 * emacs.c: Don't assume string length fits in 'int'.
10497 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10498 (main): Don't invoke strlen when not needed.
10500 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10501 (XD_DEBUG_MESSAGE): Don't waste a byte.
10503 * callproc.c (getenv_internal_1, getenv_internal)
10504 (Fgetenv_internal):
10505 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10507 * lread.c (invalid_syntax): Omit length argument.
10508 All uses changed. This doesn't fix a bug, but it simplifies the
10509 code away from its former Hollerith-constant appearance, and it's
10510 one less 'int' to worry about when looking at integer-overflow issues.
10511 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10513 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10514 This didn't break anything, but it didn't help either.
10515 It's confusing to put a bogus integer in a place where the actual
10516 value does not matter.
10517 (LIST_END_P): Remove unused macro and its bogus comment.
10518 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10520 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10521 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10523 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10524 We prefer signed types, and the value cannot exceed the EMACS_INT
10525 range anyway (because otherwise the length would not be representable).
10526 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10527 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10528 This avoids a GCC warning when WIDE_EMACS_INT.
10530 * indent.c (sane_tab_width): New function.
10531 (current_column, scan_for_column, Findent_to, position_indentation)
10532 (compute_motion): Use it. This is just for clarity.
10533 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10535 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10537 * lisp.h (lint_assume): New macro.
10538 * composite.c (composition_gstring_put_cache):
10539 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10541 * editfns.c, insdel.c:
10542 Omit unnecessary forward decls, to simplify future changes.
10544 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10546 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10548 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10549 Use much-faster test for byte-length change.
10550 Don't assume string byte-length fits in 'int'.
10551 Check that character arg fits in 'int'.
10552 (mapcar1): Declare byte as byte, for clarity.
10554 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10556 * fns.c (concat): Catch string overflow earlier.
10557 Do not rely on integer wraparound.
10559 * dispextern.h (struct it.overlay_strings_charpos)
10560 (struct it.selective): Now EMACS_INT, not int.
10561 * xdisp.c (forward_to_next_line_start)
10562 (back_to_previous_visible_line_start)
10563 (reseat_at_next_visible_line_start, next_element_from_buffer):
10564 Don't arbitrarily truncate the value of 'selective' to int.
10566 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10568 * composite.c: Don't truncate sizes to 'int'.
10569 (composition_gstring_p, composition_reseat_it)
10570 (composition_adjust_point): Use EMACS_INT, not int.
10571 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10572 not EMACS_UINT, for indexes.
10574 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10576 * buffer.c: Include <verify.h>.
10577 (struct sortvec.priority, struct sortstr.priority):
10578 Now EMACS_INT, not int.
10579 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10580 (struct sortstr.size, record_overlay_string)
10581 (struct sortstrlist.size, struct sortlist.used):
10582 Don't truncate size to int.
10583 (record_overlay_string): Check for size-calculation overflow.
10584 (init_buffer_once): Check at compile-time, not run-time.
10586 2011-06-22 Jim Meyering <meyering@redhat.com>
10588 Don't leak an XBM-image-sized buffer
10589 * image.c (xbm_load): Free the image buffer after using it.
10591 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10594 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10595 that Sun C diagnosed.
10596 * fns.c (secure_hash): Fix pointer signedness issue.
10597 * intervals.c (static_offset_intervals): New function.
10598 (offset_intervals): Use it.
10600 2011-06-21 Leo Liu <sdl.web@gmail.com>
10603 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10606 * fns.c (secure_hash): Rename from crypto_hash_function and change
10607 the first arg to accept symbols.
10608 (Fsecure_hash): New primitive.
10609 (syms_of_fns): New symbols.
10611 2011-06-20 Deniz Dogan <deniz@dogan.se>
10613 * process.c (Fset_process_buffer): Clarify return value in
10616 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10618 * dispnew.c (add_window_display_history): Use BVAR.
10620 * xdisp.c (debug_method_add): Use BVAR.
10621 (check_window_end, dump_glyph_matrix, dump_glyph)
10622 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10624 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10627 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10628 check till after the cache is created in init_frame_faces.
10630 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10632 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10634 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10636 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10637 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10638 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10640 Improve buffer-overflow checking (Bug#8873).
10641 * fileio.c (Finsert_file_contents):
10642 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10643 Remove the old (too-loose) buffer overflow checks.
10644 They weren't needed, since make_gap checks for buffer overflow.
10645 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10646 The old code merely checked for Emacs fixnum overflow, and relied
10647 on undefined (wraparound) behavior. The new code avoids undefined
10648 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10650 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10651 Tune. Don't use wider integers than needed. Don't use alloca.
10652 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10654 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10656 * insdel.c, lisp.h (buffer_overflow): New function.
10657 (insert_from_buffer_1, replace_range, replace_range_2):
10658 * insdel.c (make_gap_larger):
10659 * editfns.c (Finsert_char):
10660 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10662 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10664 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10666 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10668 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10669 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10671 * fileio.c: Don't assume EMACS_INT fits in off_t.
10672 (emacs_lseek): New static function.
10673 (Finsert_file_contents, Fwrite_region): Use it.
10674 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10676 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10678 * fns.c: Don't overflow int when computing a list length.
10679 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10680 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10681 truncation on 64-bit hosts. Check for QUIT every
10682 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10683 faster and is responsive enough.
10684 (Flength): Report an error instead of overflowing an integer.
10685 (Fsafe_length): Return a float if the value is not representable
10686 as a fixnum. This shouldn't happen except in contrived situations.
10687 (Fnthcdr, Fsort): Don't assume list length fits in int.
10688 (Fcopy_sequence): Don't assume vector length fits in int.
10690 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10691 (header_size, word_size): New constants.
10692 (allocate_vectorlike): Don't check size overflow here.
10693 (allocate_vector): Check it here instead, since this is the only
10694 caller of allocate_vectorlike that could cause overflow.
10695 Check that the new vector's length is representable as a fixnum.
10697 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10698 The previous code was bogus. For example, next_almost_prime (32)
10699 returned 39, which is undesirable as it is a multiple of 3; and
10700 next_almost_prime (24) returned 25, which is a multiple of 5 so
10701 why was the code bothering to check for multiples of 7?
10703 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10705 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10707 Variadic C functions now count arguments with ptrdiff_t.
10708 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10709 Back then I didn't know that the Emacs coding style prefers signed int.
10710 Also, in the meantime I found a few more instances where arguments
10711 were being counted with int, which may truncate counts on 64-bit
10712 machines, or EMACS_INT, which may be unnecessarily wide.
10713 * lisp.h (struct Lisp_Subr.function.aMANY)
10714 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10715 Arg counts are now ptrdiff_t, not size_t.
10716 All variadic functions and their callers changed accordingly.
10717 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10718 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10719 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10720 * callint.c (Fcall_interactively): Check arg count for overflow,
10721 to avoid potential buffer overrun. Use signed char, not 'int',
10722 for 'varies' array, so that we needn't bother to check its size
10723 calculation for overflow.
10724 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10725 * eval.c (apply_lambda):
10726 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10727 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10728 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10730 * callint.c (Fcall_interactively): Don't use index var as event count.
10732 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10733 * mem-limits.h (SIZE): Remove; no longer used.
10735 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10737 Remove unnecessary casts.
10738 * xterm.c (x_term_init):
10739 * xfns.c (x_set_border_pixel):
10740 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10741 These aren't needed now that we assume ANSI C.
10743 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10744 It's more likely to cause problems (due to unsigned overflow)
10747 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10749 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10751 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10753 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10755 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10757 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10759 GLYPH_CODE_FACE returns EMACS_INT, not int.
10760 * dispextern.h (merge_faces):
10761 * xfaces.c (merge_faces):
10762 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10763 Don't assume EMACS_INT fits in int.
10765 * character.h (CHAR_VALID_P): Remove unused parameter.
10766 * fontset.c, lisp.h, xdisp.c: All uses changed.
10768 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10770 * fns.c (concat): Minor tuning based on overflow analysis.
10771 This doesn't fix any bugs. Use int to hold character, instead
10772 of constantly refetching from Emacs object. Use XFASTINT, not
10773 XINT, for value known to be a character. Don't bother comparing
10774 a single byte to 0400, as it's always less.
10776 * floatfns.c (Fexpt):
10777 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10779 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10782 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10784 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10785 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10786 incorrectly succeed when S was a string, because 4294967386 was
10787 truncated before it was used.
10789 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10790 Otherwise, an out-of-range integer could cause undefined behavior
10793 * composite.c: Use int, not EMACS_INT, for characters.
10794 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10795 EMACS_INT, for values that are known to be in character range.
10796 This doesn't fix any bugs but is the usual style inside Emacs and
10797 may generate better code on 32-bit machines.
10799 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10800 This is for reasons similar to the recent CHAR_STRING fix.
10801 * charset.c (Fencode_char): Check that character arg is actually
10802 a character. Pass an int to ENCODE_CHAR.
10803 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10804 wider than 'int', as a compile-time check to prevent future regressions
10807 * character.c (char_string): Remove unnecessary casts.
10809 Make sure a 64-bit char is never passed to CHAR_STRING.
10810 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10811 by silently ignoring the top 32 bits, allowing some values
10812 that were far too large to be valid characters.
10813 * character.h: Include <verify.h>.
10814 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10815 arguments are no wider than unsigned, as a compile-time check
10816 to prevent future regressions in this area.
10818 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10819 (Fsubst_char_in_region):
10821 * xdisp.c (decode_mode_spec_coding):
10822 Adjust to CHAR_STRING's new requirement.
10823 * editfns.c (Finsert_char, Fsubst_char_in_region):
10824 * fns.c (concat): Check that character args are actually
10825 characters. Without this test, these functions did the wrong
10826 thing with wildly out-of-range values on 64-bit hosts.
10828 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10829 These casts should not be needed on 32-bit hosts, either.
10830 * keyboard.c (read_char):
10831 * lread.c (Fload): Remove casts to unsigned.
10833 * lisp.h (UNSIGNED_CMP): New macro.
10834 This fixes comparison bugs on 64-bit hosts.
10835 (ASCII_CHAR_P): Use it.
10836 * casefiddle.c (casify_object):
10837 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10838 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10839 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10840 * dispextern.h (FACE_FROM_ID):
10841 * keyboard.c (read_char): Use UNSIGNED_CMP.
10843 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10844 not to EMACS_INT, to avoid GCC warning.
10846 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10848 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10849 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10850 isn't needed on 32-bit machines.
10852 * buffer.c (Fgenerate_new_buffer_name):
10853 Use EMACS_INT for count, not int.
10854 (advance_to_char_boundary): Return EMACS_INT, not int.
10856 * data.c (Qcompiled_function): Now static.
10858 * window.c (window_body_lines): Now static.
10860 * image.c (gif_load): Rename local to avoid shadowing.
10862 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10863 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10864 * alloc.c (make_save_value): Integer argument is now of type
10865 ptrdiff_t, not int.
10866 (mark_object): Use ptrdiff_t, not int.
10867 * lisp.h (pD): New macro.
10868 * print.c (print_object): Use it.
10870 * alloc.c: Use EMACS_INT, not int, to count objects.
10871 (total_conses, total_markers, total_symbols, total_vector_size)
10872 (total_free_conses, total_free_markers, total_free_symbols)
10873 (total_free_floats, total_floats, total_free_intervals)
10874 (total_intervals, total_strings, total_free_strings):
10875 Now EMACS_INT, not int. All uses changed.
10876 (Fgarbage_collect): Compute overall total using a double, so that
10877 integer overflow is less likely to be a problem. Check for overflow
10878 when converting back to an integer.
10879 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10880 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10881 These were 'int' variables that could overflow on 64-bit hosts;
10882 they were never used, so remove them instead of repairing them.
10883 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10884 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10885 Previously, this ceilinged at INT_MAX, but that doesn't work on
10887 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10889 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10890 (allocate_vectorlike): Check for ptrdiff_t overflow.
10891 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10892 when a (possibly-narrower) signed value would do just as well.
10893 We prefer using signed arithmetic, to avoid comparison confusion.
10895 * alloc.c: Catch some string size overflows that we were missing.
10896 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10897 for convenience in STRING_BYTES_MAX.
10898 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10899 The definition here is exact; the one in lisp.h was approximate.
10900 (allocate_string_data): Check for string overflow. This catches
10901 some instances we weren't catching before. Also, it catches
10902 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10903 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10904 and ptrdiff_t and EMACS_INT are both 64 bits.

11348 * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
11350 Minor fixes for signed vs unsigned integers.
11351 * character.h (MAYBE_UNIFY_CHAR):
11352 * charset.c (maybe_unify_char):
11353 * keyboard.c (read_char, reorder_modifiers):
11354 XINT -> XFASTINT, since the integer must be nonnegative.
11355 * ftfont.c (ftfont_spec_pattern):
11356 * keymap.c (access_keymap, silly_event_symbol_error):
11357 XUINT -> XFASTINT, since the integer must be nonnegative.
11358 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
11359 since it makes no difference and we prefer signed.
11360 * keyboard.c (record_char): Use XUINT when all the neighbors do.
11361 (access_keymap): NATNUMP -> INTEGERP, since the integer must be
11364 2011-06-06 Stefan Monnier <monnier@iro.umontreal.ca>

11407 (Fselected_window, select_window, Fselect_window): Move up in
11408 code. Minor doc-string fixes.
11410 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
11412 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
11413 Do not assume that spare memory exists; that assumption is valid
11414 only if SYSTEM_MALLOC.
11415 (LARGE_REQUEST): New macro, so that the issue of large requests
11416 is separated from the issue of spare memory.
11418 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
11420 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

11446 New error handlers.
11447 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
11448 Obey Vx_select_enable_clipboard_manager. Catch errors in
11449 x_clipboard_manager_save (Bug#8779).
11450 (Vx_select_enable_clipboard_manager): New variable.
11451 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11453 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11455 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11457 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11459 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11460 in the current matrix if keep_current_p is non-zero.

11466 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11468 Support bidi reordering of text covered by display properties.
11470 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11471 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11472 (bidi_cache_search, bidi_cache_iterator_state)
11473 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11474 (bidi_level_of_next_char, bidi_move_to_visually_next):
11475 Support character positions inside a run of characters covered by a
11477 (bidi_paragraph_init, bidi_resolve_explicit_1)
11478 (bidi_level_of_next_char): Call bidi_fetch_char and
11479 bidi_fetch_char_advance instead of FETCH_CHAR and

11482 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11484 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11485 instead of using explicit *_CHAR codes.
11486 (bidi_resolve_explicit, bidi_resolve_weak):
11487 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11488 bidirectional text is supported only in multibyte buffers.
11489 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11490 it to initialize the frame_window_p member of struct bidi_it.
11491 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11492 (bidi_resolve_explicit, bidi_resolve_weak)

11494 bidi_it->nchars is non-positive.
11495 (bidi_level_of_next_char): Don't try to lookup the cache for the
11496 next/previous character if nothing is cached there yet, or if we
11497 were just reseat()'ed to a new position.
11499 * xdisp.c (set_cursor_from_row): Set start and stop points
11500 according to the row's direction when priming the loop that looks
11501 for the glyph on which to display cursor.
11502 (single_display_spec_intangible_p): Function deleted.
11503 (display_prop_intangible_p): Reimplement to call
11504 handle_display_spec instead of single_display_spec_intangible_p.
11505 Accept 3 additional arguments needed by handle_display_spec.
11506 This fixes incorrect cursor motion across display property with complex
11507 values: lists, `(when COND...)' forms, etc.
11508 (single_display_spec_string_p): Support property values that are
11509 lists with the argument STRING its top-level element.
11510 (display_prop_string_p): Fix the condition for processing a
11511 property that is a list to be consistent with handle_display_spec.
11512 (handle_display_spec): New function, refactored from the
11513 last portion of handle_display_prop.
11514 (compute_display_string_pos): Accept additional argument
11515 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11516 value of a `display' property is a "replacing spec".
11517 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11518 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11519 the display property, but just return a value indicating whether
11520 the display property will replace the characters it covers.
11521 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11522 frame_window_p members of struct bidi_it.
11523 (compute_display_string_pos, compute_display_string_end):
11525 (push_it): Accept second argument POSITION, where pop_it should
11526 jump to continue iteration.
11527 (reseat_1): Initialize bidi_it.disp_pos.
11529 * keyboard.c (adjust_point_for_property): Adjust the call to
11530 display_prop_intangible_p to its new signature.
11532 * dispextern.h (struct bidi_it): New member frame_window_p.
11533 (bidi_init_it): Update prototypes.
11534 (display_prop_intangible_p): Update prototype.
11535 (compute_display_string_pos, compute_display_string_end):
11536 Declare prototypes.
11537 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11540 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11542 Malloc failure behavior now depends on size of allocation.
11543 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11544 * lisp.h: Change signatures accordingly.
11545 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11546 All callers changed. (Bug#8762)
11548 * gnutls.c: Use Emacs's memory allocators.
11549 Without this change, the gnutls library would invoke malloc etc.
11550 directly, which causes problems on non-SYNC_INPUT hosts, and which
11551 runs afoul of improving memory_full behavior. (Bug#8761)
11552 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11553 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11554 xfree instead of the default malloc, realloc, free.
11555 (Fgnutls_boot): No need to check for memory allocation failure,
11556 since xmalloc does that for us.
11558 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11559 * category.c (hash_get_category_set):
11560 * ccl.c (ccl_driver):

11573 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11574 * image.c (make_image, search_image_cache, lookup_image)
11575 (xpm_put_color_table_h):
11576 * lisp.h (struct Lisp_Hash_Table):
11577 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11578 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11579 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11580 * alloc.c (allocate_vectorlike):
11581 Check for overflow in vector size calculations.
11582 * ccl.c (ccl_driver):
11583 Check for overflow when converting EMACS_INT to int.
11584 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11585 need to be updated by these changes.
11586 * fns.c (make_hash_table, maybe_resize_hash_table):
11587 Check for integer overflow with large hash tables.
11588 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11589 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11590 (SXHASH_REDUCE): New macro.
11591 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11592 Use it instead of discarding useful hash info with large hash values.
11593 (sxhash_float): New function.
11594 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11595 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11596 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11597 Rewrite to use FIXNUM_BITS, as this simplifies things.
11598 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11599 Adjust signatures to match updated version of code.
11600 (consing_since_gc): Now EMACS_INT, since a single hash table can
11601 use more than INT_MAX bytes.
11603 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11605 Make it possible to build with GCC-4.6+ -O2 -flto.
11607 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11609 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11611 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11612 Call minibuffer-inactive-mode.
11614 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11616 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11617 Update dependencies.
11619 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11621 * data.c (init_data): Remove code for UTS, this system is not
11624 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11626 Don't force ./temacs to start in terminal mode.
11628 * frame.c (make_initial_frame): Initialize faces in all cases, not
11629 only when CANNOT_DUMP is defined.
11630 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11632 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11634 * dispnew.c (add_window_display_history): Use const for the string
11635 pointer. Remove declaration, not needed.
11637 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11639 Use 'inline', not 'INLINE'.
11640 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11641 * alloc.c, fontset.c (INLINE): Remove.
11642 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11643 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11644 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11645 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11646 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11648 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11650 Make it possible to run ./temacs.
11652 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11653 syms_of_callproc does the same thing. Remove test for
11654 "initialized", do it in the caller.
11655 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11657 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11659 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11660 (read_minibuf): Use get_minibuffer.
11661 (syms_of_minibuf): Use DEFSYM.
11662 (Qmetadata): New var.
11663 * data.c (Qbuffer): Don't make it static.
11664 (syms_of_data): Use DEFSYM.
11666 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11668 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11669 (CCL_CODE_MIN): New macro.
11671 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11673 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11675 * eval.c (Qdebug): Now static.
11676 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11677 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11678 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11680 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11682 * image.c: Various fixes to ImageMagick code comments.
11683 (Fimagemagick_types): Doc fix.
11685 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11687 Minor fixes prompted by GCC 4.6.0 warnings.
11689 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11691 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11692 (x_clipboard_manager_save_all): Move extern decl to ...
11693 * xterm.h: ... here, so that it can be checked for consistency.
11695 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11697 * xselect.c (x_clipboard_manager_save_frame)
11698 (x_clipboard_manager_save_all): New functions.
11699 (Fx_clipboard_manager_save): Lisp function deleted.
11701 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11702 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11704 * xterm.h: Update prototype.
11706 2011-05-28 William Xu <william.xwl@gmail.com>
11708 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11709 exiting (Bug#8239).
11711 2011-05-28 Jim Meyering <meyering@redhat.com>
11713 Avoid a sign-extension bug in crypto_hash_function.
11714 * fns.c (to_uchar): Define.
11715 (crypto_hash_function): Use it to convert some newly-signed
11716 variables to unsigned, to avoid sign-extension bugs. For example,
11717 without this change, (md5 "truc") would evaluate to
11718 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11719 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11720 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11722 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11724 Integer overflow fixes.
11726 * dbusbind.c: Serial number integer overflow fixes.
11727 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11728 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11729 to hold a serial number that is too large for a fixnum.
11730 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11731 Check for serial numbers out of range. Decode any serial number
11732 that was so large that it became a float. (Bug#8722)
11734 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11735 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11736 Use XFASTINT rather than XUINT when numbers are nonnegative.
11737 (xd_append_arg, Fdbus_method_return_internal):
11738 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11739 arguments, check that Lisp number is nonnegative, rather than
11740 silently wrapping negative numbers around. (Bug#8722)
11741 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11744 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11746 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11748 ccl: Add integer overflow checks.
11749 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11750 (IN_INT_RANGE): New macros.
11751 (ccl_driver): Use them to check for integer overflow when
11752 decoding a CCL program. Many of the new checks are whether XINT (x)
11753 fits in int; it doesn't always, on 64-bit hosts. The new version
11754 doesn't catch all possible integer overflows, but it's an
11755 improvement. (Bug#8719)
11757 * alloc.c (make_event_array): Use XINT, not XUINT.
11758 There's no need for unsigned here.
11760 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11761 This follows up to the 2011-05-06 change that substituted uintptr_t
11762 for EMACS_INT. This case wasn't caught back then.
11764 Rework Fformat to avoid integer overflow issues.
11765 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11766 now (part of C89). Include <verify.h>.
11767 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11768 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11769 (Fformat): Avoid the prepass trying to compute sizes; it was only
11770 approximate and thus did not catch overflow reliably. Instead, walk
11771 through the format just once, formatting and computing sizes as we go,
11772 checking for integer overflow at every step, and allocating a larger
11773 buffer as needed. Keep track separately whether the format is
11774 multibyte. Keep only the most-recently calculated precision, rather
11775 than them all. Record whether each argument has been converted to
11776 string. Use EMACS_INT, not int, for byte and char and arg counts.
11777 Support field widths and precisions larger than INT_MAX. Avoid
11778 sprintf's undefined behavior with conversion specifications such as %#d
11779 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11780 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11781 formatting out-of-range floating point numbers with int
11782 formats. (Bug#8668)
11784 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11786 * data.c: Avoid integer truncation in expressions involving floats.
11787 * data.c: Include <intprops.h>.
11788 (arith_driver): When there's an integer overflow in an expression
11789 involving floating point, convert the integers to floating point
11790 so that the resulting value does not suffer from catastrophic
11791 integer truncation. For example, on a 64-bit host (* 4
11792 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11793 Do not rely on undefined behavior after integer overflow.
11795 merge count_size_as_multibyte, parse_str_to_multibyte
11796 * character.c, character.h (count_size_as_multibyte):
11797 Rename from parse_str_to_multibyte; all uses changed.
11798 Check for integer overflow.
11799 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11800 since it's now a duplicate of the other. This is more of
11801 a character than a buffer op, so better that it's in character.c.
11802 * fns.c, print.c: Adjust to above changes.
11804 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11806 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11808 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11810 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11811 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11812 (x_clipboard_manager_save): Now static.
11813 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11815 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11816 (crypto_hash_function): Now static.
11817 Fix pointer signedness problems. Avoid unnecessary initializations.
11819 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11821 * termhooks.h (Vselection_alist): Make it terminal-local.
11823 * terminal.c (create_terminal): Initialize it.
11825 * xselect.c: Support for clipboard managers.
11826 (Vselection_alist): Move to termhooks.h as terminal-local var.
11827 (LOCAL_SELECTION): New macro.
11828 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11829 (symbol_to_x_atom): Remove gratuitous arg.
11830 (x_handle_selection_request, lisp_data_to_selection_data)
11831 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11832 (x_own_selection, x_get_local_selection, x_convert_selection):
11833 New arg, specifying work frame. Use terminal-local Vselection_alist.
11834 (some_frame_on_display): Delete unused function.
11835 (Fx_own_selection_internal, Fx_get_selection_internal)
11836 (Fx_disown_selection_internal, Fx_selection_owner_p)
11837 (Fx_selection_exists_p): New optional frame arg.
11838 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11839 (x_handle_selection_clear): Don't treat other terminals with the
11840 same keyboard specially. Use the terminal-local Vselection_alist.
11841 (x_clear_frame_selections): Use Frun_hook_with_args.
11843 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11845 * xterm.h: Add support for those atoms.
11847 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11849 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11850 (converted_selections, conversion_fail_tag): New global variables.
11851 (x_selection_request_lisp_error): Free the above.
11852 (x_get_local_selection): Remove unnecessary code.
11853 (x_reply_selection_request): Args changed; handle arbitrary array
11854 of converted selections stored in converted_selections.
11855 Separate the XChangeProperty and SelectionNotify steps.
11856 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11857 (x_convert_selection): New function.
11858 (x_handle_selection_event): Simplify.
11859 (x_get_foreign_selection): Don't ignore incoming requests while
11860 waiting for an answer; this will fail when we implement
11861 SAVE_TARGETS, and seems unnecessary anyway.
11862 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11863 (Vx_sent_selection_functions): Doc fix.
11865 2011-05-26 Leo Liu <sdl.web@gmail.com>
11867 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11869 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11871 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11873 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11874 for fringe update if it has periodic bitmap.
11875 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11876 and fringe_bitmap_periodic_p.
11878 * fringe.c (get_fringe_bitmap_data): New function.
11879 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11880 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11881 row. Mark glyph row for fringe update if periodicity changed.
11883 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11884 for fringe update unless it has periodic bitmap.
11886 2011-05-25 Kenichi Handa <handa@m17n.org>
11888 * xdisp.c (get_next_display_element): Set correct it->face_id for
11889 a static composition.
11891 2011-05-24 Leo Liu <sdl.web@gmail.com>
11894 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11896 * fns.c (crypto_hash_function, Fsha1): New function.
11897 (Fmd5): Use crypto_hash_function.
11898 (syms_of_fns): Add Ssha1.
11900 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11902 * gnutls.c: Remove unused macros.
11903 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11904 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11905 Remove macros that are defined and never used.
11906 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11908 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11910 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11911 (Fx_get_selection_internal): Minor cleanup.
11912 (Fx_own_selection_internal): Rename arguments for consistency with
11915 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11917 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11919 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11921 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11923 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11925 * dispnew.c (scrolling_window): Don't exclude the case that the
11926 last enabled row in the desired matrix touches the bottom boundary.
11928 2011-05-21 Glenn Morris <rgm@gnu.org>
11930 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11931 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11932 and add some more files.
11934 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11936 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11937 report_file_error introduced by the change from 2011-05-07.
11939 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11941 * systime.h (Time): Define only if emacs is defined.
11942 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11943 where the include path doesn't have X11/X.h by default. See
11944 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11946 2011-05-20 Kenichi Handa <handa@m17n.org>
11948 * composite.c (find_automatic_composition): Fix previous change.
11950 2011-05-20 Glenn Morris <rgm@gnu.org>
11952 * lisp.mk: New file, split from Makefile.in.
11953 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11954 (shortlisp): Remove.
11955 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11957 2011-05-19 Glenn Morris <rgm@gnu.org>
11959 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11960 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11961 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11962 (lisp): Set the order to that of loadup.el.
11963 (shortlisp): Make it a copy of $lisp.
11964 (SOME_MACHINE_LISP): Remove.
11965 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11966 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11968 2011-05-18 Kenichi Handa <handa@m17n.org>
11970 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11971 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11972 (find_automatic_composition): Mostly rewrite for efficiency.
11974 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11976 * makefile.w32-in: Update dependencies.
11978 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11980 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11981 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11983 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11985 Fix some integer overflow issues, such as string length overflow.
11987 * insdel.c (count_size_as_multibyte): Check for string overflow.
11989 * character.c (lisp_string_width): Check for string overflow.
11990 Use EMACS_INT, not int, for string indexes and lengths; in
11991 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11992 the resulting string length overflows an EMACS_INT; instead,
11993 report a string overflow if no precision given. When checking for
11994 precision exhaustion, use a check that cannot possibly have
11995 integer overflow. (Bug#8675)
11996 * character.h (lisp_string_width): Adjust to new signature.
11998 * alloc.c (string_overflow): New function.
11999 (Fmake_string): Use it. This doesn't change behavior, but saves
12000 a few bytes and will simplify future changes.
12001 * character.c (string_escape_byte8): Likewise.
12002 * lisp.h (string_overflow): New decl.
12004 Fixups, following up to the user-interface timestamp change.
12005 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12006 for UI timestamps, instead of unsigned long.
12007 * msdos.c (mouse_get_pos): Likewise.
12008 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12009 * w32gui.h (Time): Define by including "systime.h" rather than by
12010 declaring it ourselves. (Bug#8664)
12012 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12013 * image.c (clear_image_cache): Likewise.
12015 * term.c (term_mouse_position): Don't assume time_t wraparound.
12017 Be more systematic about user-interface timestamps.
12018 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12019 and sometimes 'EMACS_UINT', to represent these timestamps.
12020 This change causes it to use 'Time' uniformly, as that's what X uses.
12021 This makes the code easier to follow, and makes it easier to catch
12022 integer overflow bugs such as Bug#8664.
12023 * frame.c (Fmouse_position, Fmouse_pixel_position):
12024 Use Time, not unsigned long, for user-interface timestamps.
12025 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12026 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12027 * keyboard.h (last_event_timestamp): Likewise.
12028 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12029 * menu.h (xmenu_show): Likewise.
12030 * term.c (term_mouse_position): Likewise.
12031 * termhooks.h (struct input_event.timestamp): Likewise.
12032 (struct terminal.mouse_position_hook): Likewise.
12033 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12034 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12035 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12036 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12037 what it was before.
12038 * menu.h, termhooks.h: Include "systime.h", for Time.
12040 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12041 Don't assume that the difference between two unsigned long values
12042 can fit into an integer. At this point, we know button_down_time
12043 <= event->timestamp, so the difference must be nonnegative, so
12044 there's no need to cast the result if double-click-time is
12045 nonnegative, as it should be; check that it's nonnegative, just in
12046 case. This bug is triggered when events are more than 2**31 ms
12047 apart (about 25 days). (Bug#8664)
12049 * xselect.c (last_event_timestamp): Remove duplicate decl.
12050 (x_own_selection): Remove needless cast to unsigned long.
12052 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12053 that always fit in int. Use a sentinel instead of a counter, to
12054 avoid a temp and to allay GCC's concerns about possible int overflow.
12055 * frame.h (struct frame): Use int for menu_bar_items_used
12056 instead of EMACS_INT, since it always fits in int.
12058 * menu.c (grow_menu_items): Check for int overflow.
12060 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12062 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12063 Before, the code was not consistent. These values cannot exceed
12064 2**31 - 1 so there's no need to make them unsigned.
12065 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12066 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12067 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12069 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12071 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12072 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12073 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12074 presumably because the widths might not match.
12076 * window.c (size_window): Avoid needless test at loop start.
12078 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12080 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12082 2011-05-12 Drew Adams <drew.adams@oracle.com>
12084 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12086 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12088 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12089 `width' to `bar_area_x' and `bar_area_width', respectively.
12090 (x_scroll_run): Take account of fringe background extension.
12092 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12093 Rename local vars `left' and `width' to `bar_area_x' and
12094 `bar_area_width', respectively.
12095 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12096 background extension.
12098 2011-05-10 Jim Meyering <meyering@redhat.com>
12100 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12102 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12104 * image.c (Finit_image_library): Return t for built-in image types,
12105 like pbm and xbm. (Bug#8640)
12107 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12109 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12111 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12113 * w32console.c (Fset_screen_color): Doc fix.
12114 (Fget_screen_color): New function.
12115 (syms_of_ntterm): Defsubr it.
12117 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12118 unlink the temporary file if Fcall_process didn't create it in the
12120 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12121 child process will be redirected to a file specified with `:file'.
12122 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12123 cue to call_process_cleanup not to close that handle.
12125 2011-05-07 Ben Key <bkey76@gmail.com>
12127 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12128 one of two shell specific rules, either bootstrap-temacs-CMD or
12129 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12130 to the previous implementation of the bootstrap-temacs rule.
12131 The bootstrap-temacs-CMD rule is similar to the previous
12132 implementation of the bootstrap-temacs rule except that it
12133 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12136 These changes, along with some changes to nt/configure.bat,
12137 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12138 earlier fix to add support for --cflags and --ldflags options
12139 that include quotes so that it works whether make uses cmd or
12142 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12144 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12145 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12147 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12148 a string. Handle both cases.
12149 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12150 (Fdbus_register_method): Use Qinvalid_function.
12152 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12154 * makefile.w32-in: Update dependencies.
12155 (LISP_H): Add inttypes.h and stdin.h.
12156 (PROCESS_H): Add unistd.h.
12158 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12160 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12161 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12163 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12165 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12167 * term.c (vfatal): Remove stray call to va_end.
12168 It's not needed and the C Standard doesn't allow it here anyway.
12170 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12171 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12173 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12176 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12178 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12180 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12182 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12184 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12186 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12187 * charset.c (Fdefine_charset_internal): Don't initialize
12188 charset.code_space[15]. The value was garbage, on hosts with
12189 32-bit int (Bug#8600).
12191 * lread.c (read_integer): Be more consistent with string-to-number.
12192 Use string_to_number to do the actual conversion; this avoids
12193 rounding errors and fixes some other screwups. Without this fix,
12194 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12195 (digit_to_number): Move earlier, for benefit of read_integer.
12196 Return -1 if the digit is out of range for the base, -2 if it is
12197 not a digit in any supported base. (Bug#8602)
12199 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12201 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12202 to match comment at start of function. This also removes a
12203 GCC warning about overflow in a 32+64-bit port.
12205 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12207 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12208 Reported by Stefan Monnier in
12209 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12210 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12211 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12213 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12214 (EMACS_UINTPTR): Likewise, with uintptr_t.
12216 * lisp.h: Prefer 64-bit EMACS_INT if available.
12217 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12218 on 32-bit hosts that have 64-bit int, so that they can access
12220 However, temporarily disable this change unless the temporary
12221 symbol WIDE_EMACS_INT is defined.
12223 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12225 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12226 This removes an assumption that EMACS_INT and long are the same
12227 width as pointers. The assumption is true for Emacs porting targets
12228 now, but we want to make other targets possible.
12229 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12230 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12231 In the rest of the code, change types of integers that hold casted
12232 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12233 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12234 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12235 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12236 No need to cast type when ORing.
12237 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12238 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12239 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12240 assume EMACS_INT is the same width as char *.
12241 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12242 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12243 Remove no-longer-needed casts.
12244 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12245 (xg_tool_bar_help_callback, xg_make_tool_item):
12246 Use EMACS_INTPTR to hold an integer
12247 that will be cast to void *; this can avoid a GCC warning
12248 if EMACS_INT is not the same width as void *.
12249 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12250 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12251 (current_message_1, set_message_1):
12252 Use a local to convert to proper width without a cast.
12253 * xmenu.c (dialog_selection_callback): Likewise.
12255 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12256 Also, don't assume VALBITS / RAND_BITS is less than 5,
12257 and don't rely on undefined behavior when shifting a 1 left into
12259 * lisp.h (get_random): Change signature to match.
12261 * lread.c (hash_string): Use size_t, not int, for hash computation.
12262 Normally we prefer signed values; but hashing is special, because
12263 it's better to use unsigned division on hash table sizes so that
12264 the remainder is nonnegative. Also, size_t is the natural width
12265 for hashing into memory. The previous code used 'int', which doesn't
12266 retain enough info to hash well into very large tables.
12267 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12269 * dbusbind.c: Don't possibly lose pointer info when converting.
12270 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12271 Use XPNTR rather than XHASH, so that the high-order bits of
12272 the pointer aren't lost when converting through void *.
12274 * eval.c (Fautoload): Don't double-shift a pointer.
12276 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12278 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12280 * gnutls.c (DEF_GNUTLS_FN):
12281 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12283 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12285 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12288 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12290 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12291 New version that can reserve upto 2GB of heap space.
12293 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12295 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12297 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12299 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12300 `gnutls_certificate_set_x509_key_file'.
12302 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

12305 Update dependencies.
12307 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12309 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12310 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12311 Remove unused parameter `fildes'.
12312 * process.c (read_process_output, send_process): Don't pass it.
12314 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12316 Fix previous change: the library cache is defined in w32.c.
12317 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12318 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12320 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12322 Implement dynamic loading of GnuTLS on Windows.
12324 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12325 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12326 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12329 * gnutls.c (Qgnutls_dll): Define.

12336 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12337 (emacs_gnutls_write, emacs_gnutls_read)
12338 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12339 (Fgnutls_available_p): New function.
12340 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

12348 (w32_delayed_load): Move to w32.c.
12350 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12352 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12353 (w32_delayed_load): Move from image.c. When loading a library, record
12354 its filename in the :loaded-from property of the library id.
12355 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12356 Initialize and staticpro them.
12357 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12359 * process.c: Include lisp.h before w32.h, not after.
12360 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12361 instead of gnutls_record_check_pending.
12363 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12365 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12367 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12368 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12371 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12373 * xterm.c (x_set_frame_alpha): Do not set property on anything
12374 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12376 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12378 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12380 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12382 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12383 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12389 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)

12396 * sysdep.c (wait_for_termination_1): Make static.
12397 (wait_for_termination, interruptible_wait_for_termination):
12398 Move after wait_for_termination_1.
12400 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12402 * sysdep.c (interruptible_wait_for_termination): New function
12403 which is like wait_for_termination, but allows keyboard
12406 * callproc.c (Fcall_process): Add (:file "file") as an option for
12408 (Fcall_process_region): Ditto.
12410 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12412 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12413 rather than `XVECTOR (FOO)->size'.
12415 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12416 inttypes.h, as a gnulib replacement is used if it not available in
12419 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12421 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12422 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12423 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12425 * coding.c (coding_alloc_by_realloc): Error out if destination
12426 will grow beyond MOST_POSITIVE_FIXNUM.
12427 (decode_coding_emacs_mule): Abort if there isn't enough place in
12428 charbuf for the composition carryover bytes. Reserve an extra
12429 space for up to 2 characters produced in a loop.
12430 (decode_coding_iso_2022): Abort if there isn't enough place in
12431 charbuf for the composition carryover bytes.
12433 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12435 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12436 aborting when %lld or %lll format is passed.
12437 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12438 %llo or %llx format is passed. (Bug#8545)
12440 * window.c (window_scroll_line_based): Use a marker instead of
12441 simple variables to record original value of point. (Bug#7952)
12443 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12444 produced by %s or %c overflows available buffer space. (Bug#8545)
12446 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12448 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12449 (SIZE_MAX): Move defn after all includes, as they might #define it.
12451 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12453 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12455 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12457 * keyboard.c (Qdelayed_warnings_hook): Define.
12458 (command_loop_1): Run `delayed-warnings-hook'
12459 if Vdelayed_warnings_list is non-nil.
12460 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12461 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12463 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12465 * doprnt.c (doprnt): Don't return value smaller than the buffer
12466 size if the message was truncated. (Bug#8545).
12468 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12470 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12471 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12473 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12475 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12477 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12479 * makefile.w32-in: Update dependencies.
12481 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12483 Improve `doprnt' and its usage. (Bug#8545)
12484 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12485 `format_end'. Remove support for %l as a conversion specifier.
12486 Don't use xrealloc. Improve diagnostics when the %l size modifier
12487 is used. Update the commentary.
12489 * eval.c (verror): Simplify calculation of size_t.
12491 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12494 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12496 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12499 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12501 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12502 This makes this file independent of the recent pseudovector change.
12504 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12506 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12508 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12509 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12510 Remove unused local.
12511 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12513 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12514 GCC 4.6.0 optimizes based on type-based alias analysis.
12515 For example, if b is of type struct buffer * and v of type struct
12516 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12517 != &v->size, and therefore "v->size = 1; b->size = 2; return
12518 v->size;" must therefore return 1. This assumption is incorrect
12519 for Emacs, since it type-puns struct Lisp_Vector * with many other
12520 types. To fix this problem, this patch adds a new type struct
12521 vectorlike_header that documents the constraints on layout of vectors
12522 and pseudovectors, and helps optimizing compilers not get fooled
12523 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12524 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12525 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12527 (XSETPVECTYPE): Rewrite in terms of new macro.
12528 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12529 This is a bit clearer, and further avoids the possibility of
12530 undesirable aliasing.
12531 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12532 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12533 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12534 since Lisp_Subr is a special case (no "next" field).
12535 (ASIZE): Now uses header.size rather than size.
12536 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12537 to avoid the hassle of writing XVECTOR (foo)->header.size.
12538 (struct vectorlike_header): New type.
12539 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12540 object, to help avoid aliasing.
12541 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12542 (SUBRP): Likewise, since Lisp_Subr is a special case.
12543 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12544 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12545 (struct Lisp_Hash_Table): Combine first two members into a single
12546 struct vectorlike_header member. All uses of "size" and "next" members
12547 changed to be "header.size" and "header.next".
12548 * buffer.h (struct buffer): Likewise.
12549 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12550 * frame.h (struct frame): Likewise.
12551 * process.h (struct Lisp_Process): Likewise.
12552 * termhooks.h (struct terminal): Likewise.
12553 * window.c (struct save_window_data, struct saved_window): Likewise.
12554 * window.h (struct window): Likewise.
12555 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12556 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12557 * buffer.c (init_buffer_once): Likewise.
12558 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12560 * process.c (Fformat_network_address): Use local var for size,
12563 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12565 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12566 * data.c (atof): Remove decl; no longer used or needed.
12567 (digit_to_number): Move to lread.c.
12568 (Fstring_to_number): Use new string_to_number function, to be
12569 consistent with how the Lisp reader treats infinities and NaNs.
12570 Do not assume that floating-point numbers represent EMACS_INT
12571 without losing information; this is not true on most 64-bit hosts.
12572 Avoid double-rounding errors, by insisting on integers when
12573 parsing non-base-10 numbers, as the documentation specifies.
12574 * lisp.h (string_to_number): New decl, replacing ...
12575 (isfloat_string): Remove.
12576 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12577 (read1): Do not accept +. and -. as integers; this
12578 appears to have been a coding error. Similarly, do not accept
12579 strings like +-1e0 as floating point numbers. Do not report
12580 overflow for integer overflows unless the base is not 10 which
12581 means we have no simple and reliable way to continue.
12582 Break out the floating-point parsing into a new
12583 function string_to_number, so that Fstring_to_number parses
12584 floating point numbers consistently with the Lisp reader.
12585 (digit_to_number): Move here from data.c. Make it static inline.
12586 (E_CHAR, EXP_INT): Remove, replacing with ...
12587 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12588 (string_to_number): New function, replacing isfloat_string.
12589 This function checks for valid syntax and produces the resulting
12590 Lisp float number too. Rework it so that string-to-number
12591 no longer mishandles examples like "1.0e+". Use strtoumax,
12592 so that overflow for non-base-10 numbers is reported only when
12593 there's no portable and simple way to convert to floating point.
12595 * textprop.c (set_text_properties_1): Rewrite for clarity,
12596 and to avoid GCC warning about integer overflow.
12598 * intervals.h (struct interval): Use EMACS_INT for members
12599 where EMACS_UINT might cause problems. See
12600 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12601 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12602 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12604 (offset_intervals): Tell GCC not to worry about length overflow
12605 when negating a negative length.
12607 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12608 (overrun_check_free): Likewise.
12610 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12611 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12614 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12615 (gnutls_make_error): Rename local to avoid shadowing.
12616 (gnutls_emacs_global_deinit): ifdef out; not used.
12617 (Fgnutls_boot): Use const for pointer to readonly storage.
12618 Comment out unused local. Fix pointer signedness problems.
12620 * lread.c (openp): Don't stuff size_t into an 'int'.
12621 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12622 about possible signed overflow.
12624 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12625 (GDK_KEY_g): Don't define if already defined.
12626 (xg_prepare_tooltip): Avoid pointer signedness problem.
12627 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12629 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12630 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12632 * xfns.c (Fx_window_property): Simplify a bit,
12633 to make a bit faster and to avoid GCC 4.6.0 warning.
12634 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12636 * fns.c (internal_equal): Don't assume size_t fits in int.
12638 * alloc.c (compact_small_strings): Tighten assertion a little.
12640 Replace pEd with more-general pI, and fix some printf arg casts.
12641 * lisp.h (pI): New macro, generalizing old pEd macro to other
12642 conversion specifiers. For example, use "...%"pI"d..." rather
12643 than "...%"pEd"...".
12644 (pEd): Remove. All uses replaced with similar uses of pI.
12645 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12646 * alloc.c (check_pure_size): Don't overflow by converting size to int.

12650 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12651 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12653 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12654 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12655 * print.c (safe_debug_print, print_object): Likewise.
12656 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12658 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12659 avoiding the 0 flag, which is not portable.

12661 * region-cache.c (pp_cache): Likewise.
12662 * xdisp.c (decode_mode_spec): Likewise.

12664 behavior on 64-bit hosts with printf arg.
12665 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12666 (x_stop_queuing_selection_requests): Likewise.
12667 (x_get_window_property): Don't truncate byte count to an 'int'
12670 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12671 here, since it parses constructs like leading '-' and spaces,
12672 which are not wanted; and it overflows with large numbers.
12673 Instead, simply match F[0-9]+, which is what is wanted anyway.
12675 * alloc.c: Remove unportable assumptions about struct layout.
12676 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12677 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12678 (allocate_vectorlike, make_pure_vector): Use the new macros,
12679 plus offsetof, to remove unportable assumptions about struct layout.
12680 These assumptions hold on all porting targets that I know of, but
12681 they are not guaranteed, they're easy to remove, and removing them
12682 makes further changes easier.
12684 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12685 This doesn't fix a bug but makes the code clearer.
12686 (string_overrun_cookie): Now const. Use initializers that
12687 don't formally overflow signed char, to avoid warnings.
12688 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12689 can cause Emacs to crash when string overrun checking is enabled.
12690 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12691 multiple of sizeof (EMACS_INT); it need not be, if
12692 alignof(EMACS_INT) < sizeof (EMACS_INT).
12693 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12695 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12727 Improve doprnt and its use in verror. (Bug#8545)
12728 * doprnt.c (doprnt): Document the set of format control sequences
12729 supported by the function. Use SAFE_ALLOCA instead of always
12732 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12733 is one byte too soon. Don't use xrealloc; instead xfree and

12745 docstring. Start callback support.
12746 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12747 unless a fatal error occurred. Call gnutls_alert_send_appropriate

12851 codepoint of an invalid character, to avoid displaying a bogus
12854 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12855 `error', not SYMBOL_NAME itself.

12860 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12861 to `error' in error message about FINAL_CHAR argument. Make sure
12862 FINAL_CHAR is a character, and use %c when it is passed as
12863 argument to `error'.
12865 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12867 * s/ms-w32.h (localtime): Redirect to sys_localtime.
12869 * w32.c: Include <time.h>.

12929 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
12930 by pacifying GCC about it. Maybe it's time to retire it?
12931 * xfaces.c (USG, __TIMEVAL__): Likewise.
12933 * dispextern.h (struct redisplay_interface): Rename param
12934 to avoid shadowing.
12935 * termhooks.h (struct terminal): Likewise.

13052 * nsfont.m: Fixed bugs in ns_get_family and
13053 ns_descriptor_to_entity that were caused by using free to
13054 deallocate memory blocks that were allocated by xmalloc (via
13055 xstrdup). This caused Emacs to crash when compiled with
13056 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13057 --enable-checking=xmallocoverrun). xfree is now used to
13058 deallocate these memory blocks.

13072 (emacs_read, emacs_write): Remove check for negative size, as the
13073 Emacs source code has been audited now.
13074 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
13075 (emacs_read, emacs_write): Use it.
13076 * process.c (send_process): Adjust to the new signatures of
13077 emacs_write and emacs_gnutls_write. Do not attempt to store
13078 a byte offset into an 'int'; it might overflow.

13105 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
13107 Improve C-level modularity by making more things 'static'.

13526 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13528 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13529 when at ZV. (Bug#8487)
13531 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13533 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13535 * keyboard.c (parse_tool_bar_item): Likewise.
13536 * sound.c (sound_cleanup, alsa_close): Likewise.
13537 * termcap.c (tgetent): Likewise.
13538 * xfns.c (x_default_font_parameter): Likewise.
13539 * xsettings.c (read_and_apply_settings): Likewise.
13541 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13542 (overrun_check_free): Protoize.
13544 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13546 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13547 since callers should never pass a negative size.
13548 Change the signature to match that of plain 'read' and 'write'; see
13549 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13550 * lisp.h: Update prototypes of emacs_write and emacs_read.
13552 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13554 * xdisp.c (redisplay_window): Don't try to determine the character
13555 position of the scroll margin if the window start point w->startp
13556 is outside the buffer's accessible region. (Bug#8468)
13558 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13560 Fix write-region and its subroutines for buffers > 2GB.
13561 * fileio.c (a_write, e_write): Modify declaration of arguments and
13562 local variables to support buffers larger than 2GB.
13563 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13565 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13566 argument, local variables, and return value.
13568 * lisp.h: Update prototypes of emacs_write and emacs_read.
13570 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13572 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13574 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13576 Fix more problems found by GCC 4.6.0's static checks.
13578 * xdisp.c (vmessage): Use a better test for character truncation.
13580 * charset.c (load_charset_map): <, not <=, for optimization,
13581 and to avoid potential problems with integer overflow.
13582 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13583 * casetab.c (set_identity, shuffle): Likewise.
13584 * editfns.c (Fformat): Likewise.
13585 * syntax.c (skip_chars): Likewise.
13587 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13588 This also lets GCC 4.6.0 generate slightly better loop code.
13590 * callint.c (Fcall_interactively): <, not <=, for optimization.
13591 (Fcall_interactively): Count the number of arguments produced,
13592 not the number of arguments given. This is simpler and lets GCC
13593 4.6.0 generate slightly better code.
13595 * ftfont.c: Distingish more carefully between FcChar8 and char.
13596 The previous code passed unsigned char * to a functions like
13597 strlen and xstrcasecmp that expect char *, which does not
13598 conform to the C standard.
13599 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13600 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13601 char * when the C standard requires it.
13603 * keyboard.c (read_char): Remove unused var.
13605 * eval.c: Port to Windows vsnprintf (Bug#8435).
13606 Include <limits.h>.
13607 (SIZE_MAX): Define if the headers do not.
13608 (verror): Do not give up if vsnprintf returns a negative count.
13609 Instead, grow the buffer. This ports to Windows vsnprintf, which
13610 does not conform to C99. Problem reported by Eli Zaretskii.
13611 Also, simplify the allocation scheme, by avoiding the need for
13612 calling realloc, and removing the ALLOCATED variable.
13614 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13616 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13617 But keep the doprint source code for now, as we might revamp it
13618 and use it again (Bug#8435).
13619 * lisp.h (doprnt): Remove.
13620 * Makefile.in (base_obj): Remove doprnt.o.
13621 * deps.mk (doprnt.o): Remove.
13623 error: Print 32- and 64-bit integers portably (Bug#8435).
13624 Without this change, on typical 64-bit hosts error ("...%d...", N)
13625 was used to print both 32- and 64-bit integers N, which relied on
13626 undefined behavior.
13627 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13628 * lisp.h (error, verror): Mark as printf-like functions.
13629 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13630 Report overflow in size calculations when allocating printf buffer.
13631 Do not truncate output string at its first null byte.
13632 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13633 Truncate the output at a character boundary, since vsnprintf does not
13635 * charset.c (check_iso_charset_parameter): Convert internal
13636 character to string before calling 'error', since %c now has the
13638 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13639 overflow when computing char to be passed to 'error'. Do not
13640 pass Lisp_Object to 'error'; pass the integer instead.
13641 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13642 formatted with plain %d.
13644 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13646 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13648 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13650 * xterm.c (x_catch_errors): Remove duplicate declaration.
13652 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13654 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13656 2011-04-10 Jim Meyering <meyering@redhat.com>
13658 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13659 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13660 return ssize_t not "int", and use size_t as the buffer length.
13661 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13662 * gnutls.h: Update declarations.
13663 * process.c (read_process_output): Use ssize_t, to match.
13664 (send_process): Likewise.
13666 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13668 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13670 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13672 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13673 Use unsigned char, to match FcChar8 type definition.
13675 * xterm.c (handle_one_xevent):
13676 * xmenu.c (create_and_show_popup_menu):
13677 * xselect.c (x_decline_selection_request)
13678 (x_reply_selection_request): Avoid type-punned deref of X events.
13680 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13682 Fix some uses of `int' instead of EMACS_INT.
13683 * search.c (string_match_1, fast_string_match)
13684 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13685 (scan_buffer, find_next_newline_no_quit)
13686 (find_before_next_newline, search_command, Freplace_match)
13687 (Fmatch_data): Make some `int' variables be EMACS_INT.
13689 * xdisp.c (display_count_lines): 3rd argument and return value now
13690 EMACS_INT. All callers changed.
13691 (pint2hrstr): Last argument is now EMACS_INT.
13693 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13694 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13695 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13696 (decode_coding_utf_16, decode_coding_emacs_mule)
13697 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13698 (decode_coding_ccl, decode_coding_charset)
13699 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13700 (decode_coding_iso_2022, decode_coding_emacs_mule)
13701 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13702 <char_offset, last_offset>: Declare EMACS_INT.
13703 (encode_coding_utf_8, encode_coding_utf_16)
13704 (encode_coding_emacs_mule, encode_invocation_designation)
13705 (encode_designation_at_bol, encode_coding_iso_2022)
13706 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13707 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13709 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13710 (encode_invocation_designation): Last argument P_NCHARS is now
13712 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13713 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13715 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13718 * ccl.c (Fccl_execute_on_string): Declare some variables
13721 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13723 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13725 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13727 * process.c (Fformat_network_address): Doc fix.
13729 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13731 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13733 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13735 * keyboard.c (read_char): Call Lisp function help-form-show,
13736 instead of using internal_with_output_to_temp_buffer.
13737 (Qhelp_form_show): New var.
13738 (syms_of_keyboard): Use DEFSYM macro.
13740 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13742 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13744 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13746 * process.c (Flist_processes): Remove to Lisp.
13747 (list_processes_1): Delete.
13749 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13751 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13753 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13755 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13757 Fix more problems found by GCC 4.6.0's static checks.
13759 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13761 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13763 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13765 * xdisp.c (vmessage): Mark as a printf-like function.
13767 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13769 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13771 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13772 printf-like functions.
13773 (tiff_load): Add casts to remove these marks before passing them
13774 to system-supplied API.
13776 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13778 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13779 This avoids several warnings with gcc -Wstrict-overflow.
13780 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13781 directly, rather than having caller test rule sign. This avoids
13782 some unnecessary tests.
13783 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13784 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13785 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13787 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13788 (xfont_open): Avoid unnecessary tests.
13790 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13792 * composite.h, composite.c (composition_gstring_put_cache):
13793 Use EMACS_INT, not int, for length.

13796 breaking out part of COMPOSITION_DECODE_RULE.
13797 (COMPOSITION_DECODE_RULE): Use it.
13798 * composite.c (get_composition_id): Remove unused local vars,
13799 by using the new macro.
13801 * textprop.c (set_text_properties_1): Change while to do-while,
13802 since the condition is always true at first.
13804 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13805 (interval_deletion_adjustment): Return unsigned value.
13808 * process.c (list_processes_1, create_pty, read_process_output):

13818 (update_syntax_table): Use unsigned instead of int.
13820 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13821 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13822 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13824 * print.c (print_error_message): Avoid int overflow.
13826 * font.c (font_list_entities): Redo for clarity,
13827 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13829 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13830 (font_score): Avoid potential overflow in diff calculation.
13832 * fns.c (substring_both): Remove var that is set but not used.
13833 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13835 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13837 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13838 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13839 can always succeed if overflow has undefined behavior.
13841 * search.c (boyer_moore, wordify): Remove vars set but not used.
13842 (wordify): Omit three unnecessary tests.
13844 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13845 All callers changed. This avoids the need for an unused var.
13847 * casefiddle.c (casify_region): Remove var that is set but not used.
13849 * dired.c (file_name_completion): Remove var that is set but not used.
13851 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13853 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13854 (Finsert_file_contents): Remove unnecessary code checking fd.
13856 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13857 Check for integer overflow on size calculations.
13859 * buffer.c (Fprevious_overlay_change): Remove var that is set
13862 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13863 Remove vars that are set but not used.
13864 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13865 (timer_check_2): Mark vars as initialized.
13867 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13869 * image.c (lookup_image): Remove var that is set but not used.
13870 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13872 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13873 that are set but not used.
13875 * xfns.c (make_invisible_cursor): Don't return garbage
13876 if XCreateBitmapFromData fails (Bug#8410).
13878 * xselect.c (x_get_local_selection, x_handle_property_notify):
13879 Remove vars that are set but not used.
13881 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13882 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

13891 (map_tty_color) [!defined MSDOS]: Likewise.
13893 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13895 * coding.c: Remove vars that are set but not used.
13896 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13897 All callers changed.
13898 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13899 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13900 (decode_coding_charset): Remove vars that are set but not used.
13902 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13903 that is set but not used.
13905 * print.c (print_object): Remove var that is set but not used.
13907 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13908 The gnulib version avoids calling malloc in the usual case,
13909 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13910 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13911 * filelock.c (current_lock_owner): Likewise.
13912 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13913 * sysdep.c: Include allocator.h, careadlinkat.h.
13914 (emacs_no_realloc_allocator): New static constant.
13915 (emacs_readlink): New function.
13916 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13917 ../lib/careadlinkat.h.
13919 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13921 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13922 first non-nil return value).
13924 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13926 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13927 if not defined (Bug#8403).
13929 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13931 * xdisp.c (display_count_lines): Remove parameter `start',
13932 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13933 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13934 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13936 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13937 and thereabouts. All callers changed.
13938 (get_per_char_metric): Remove parameter `f', unused since
13939 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13941 2011-04-02 Jim Meyering <meyering@redhat.com>
13943 do not dereference NULL upon failed strdup
13944 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13945 (ns_get_family): Likewise.
13947 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13949 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13951 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13953 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

13969 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13971 (syms_of_lread): Declare `lexical-binding'.
13973 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13975 * keyboard.c (eval_dyn): New fun.
13976 (menu_item_eval_property): Use it.
13978 * image.c (parse_image_spec): Use Ffunctionp.
13980 * fns.c (concat, mapcar1): Accept byte-code-functions.
13982 * eval.c (Fsetq): Handle lexical vars.
13983 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13984 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13985 (FletX, Flet): Obey lexical binding.
13986 (Fcommandp): Handle closures.
13987 (Feval): New `lexical' arg.
13988 (eval_sub): New function extracted from Feval. Use it almost
13989 everywhere where Feval was used. Look up vars in lexical env.
13991 (Ffunctionp): Move from subr.el.
13992 (Ffuncall): Handle closures.
13993 (apply_lambda): Remove `eval_flags'.
13994 (funcall_lambda): Handle closures and new byte-code-functions.
13995 (Fspecial_variable_p): New function.
13996 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13997 but without exporting it to Lisp.
13999 * doc.c (Fdocumentation, store_function_docstring):
14000 * data.c (Finteractive_form): Handle closures.
14002 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14005 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14007 (exec_byte_code): New function extracted from Fbyte_code to handle new
14008 calling convention for byte-code-functions. Add new byte-codes.
14010 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14012 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14014 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14016 * xdisp.c (redisplay_internal): Fix prototype.
14018 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14020 * xdisp.c (SCROLL_LIMIT): New macro.
14021 (try_scrolling): Use it when setting scroll_limit.
14022 Limit scrolling to 100 screen lines.
14023 (redisplay_window): Even when falling back on "recentering",
14024 position point in the window according to scroll-conservatively,
14025 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14027 (try_scrolling): When point is above the window, allow searching
14028 as far as scroll_max, or one screenful, to compute vertical
14029 distance from PT to the scroll margin position. This prevents
14030 try_scrolling from unnecessarily failing when
14031 scroll-conservatively is set to a value slightly larger than the
14032 window height. Clean up the case of PT below the margin at bottom
14033 of window: scroll_max can no longer be INT_MAX. When aggressive
14034 scrolling is in use, don't let point enter the opposite scroll
14035 margin as result of the scroll.
14036 (syms_of_xdisp) <scroll-conservatively>: Document the
14037 threshold of 100 lines for never-recentering scrolling.
14039 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14041 * dispextern.h (move_it_by_lines):
14042 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14043 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14044 (message_log_check_duplicate): Remove parameters `prev_bol' and
14045 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14046 (redisplay_internal): Remove parameter `preserve_echo_area',
14047 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14049 * indent.c (Fvertical_motion):
14050 * window.c (window_scroll_pixel_based, Frecenter):
14051 Don't pass `need_y_p' to `move_it_by_lines'.
14053 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14055 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14056 steal a few bits to be more compact.
14057 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14058 Remove unneeded casts.
14060 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14062 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14064 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14065 binding" message (bug#7967).
14067 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14069 Fix more problems found by GCC 4.6.0's static checks.
14071 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14072 Remove unused local var.
14074 * editfns.c (Fmessage_box): Remove unused local var.
14076 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14077 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14078 Omit unused local vars.
14079 * window.c (shrink_windows): Omit unused local var.
14080 * menu.c (digest_single_submenu): Omit unused local var.
14081 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14082 Omit unused local var.
14084 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14085 Don't assume string length fits in int.
14086 (keyremap_step, read_key_sequence): Use size_t for sizes.
14087 (read_key_sequence): Don't check last_real_key_start redundantly.
14089 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14090 instead of alloca (Bug#8344).
14092 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14093 (Fbacktrace_frame): Don't assume nframes fits in int.
14095 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14097 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14100 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14102 * cm.c (calccost): Turn while-do into do-while, for clarity.
14104 * keyboard.c (syms_of_keyboard): Use the same style as later
14105 in this function when indexing through an array. This also
14106 works around GCC bug 48267.
14108 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14110 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14112 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14113 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14115 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14116 This avoids undefined behavior on integer overflow, and is a bit
14117 more convenient anyway since it is compared to a size_t variable.
14119 Variadic C functions now count arguments with size_t, not int.
14120 This avoids an unnecessary limitation on 64-bit machines, which
14121 caused (substring ...) to crash on large vectors (Bug#8344).
14122 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14123 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14124 All variadic functions and their callers changed accordingly.
14125 (struct gcpro.nvars): Now size_t, not int. All uses changed.
14126 * data.c (arith_driver, float_arith_driver): Likewise.
14127 * editfns.c (general_insert_function): Likewise.
14128 * eval.c (struct backtrace.nargs, interactive_p)
14129 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14130 (funcall_lambda, mark_backtrace): Likewise.
14131 * fns.c (concat): Likewise.
14132 * frame.c (x_set_frame_parameters): Likewise.
14133 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14134 0 if not found, not -1. All callers changed.
14136 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14137 (stack_copy_size): Now size_t, not int.
14138 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14140 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14142 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14143 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14144 All callers changed.
14146 * lisp.h (multibyte_char_to_unibyte):
14147 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14148 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14149 * character.h (CHAR_TO_BYTE8):
14150 * cmds.c (internal_self_insert):
14151 * editfns.c (general_insert_function):
14152 * keymap.c (push_key_description):
14153 * search.c (Freplace_match):
14154 * xdisp.c (message_dolog, set_message_1): All callers changed.
14156 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14158 * keyboard.c (safe_run_hook_funcall): New function.
14159 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14160 don't set the hook to nil, but remove the offending function instead.
14161 (Qcommand_hook_internal): Remove, unused.
14162 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14163 Vcommand_hook_internal.
14165 * eval.c (enum run_hooks_condition): Remove.
14166 (funcall_nil, funcall_not): New functions.
14167 (run_hook_with_args): Call each function through a `funcall' argument.
14168 Remove `cond' argument, now redundant.
14169 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14170 (Frun_hook_with_args_until_failure): Adjust accordingly.
14171 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14173 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14175 * dispextern.h (string_buffer_position): Remove declaration.
14177 * print.c (strout): Remove parameter `multibyte', unused since
14178 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14180 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14181 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14182 All callers changed.
14184 * w32.c (_wsa_errlist): Use braces for struct initializers.
14186 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14187 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14188 All callers changed.
14189 (string_buffer_position): Likewise. Also, make static (it's never
14190 used outside xdisp.c).
14191 (cursor_row_p): Remove parameter `w', unused since
14192 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14194 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14195 All callers changed.
14197 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14199 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
14201 2011-03-27 Anders Lindgren <andlind@gmail.com>
14203 * nsterm.m (ns_menu_bar_is_hidden): New variable.
14204 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
14205 (ns_update_auto_hide_menu_bar): New functions.
14206 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

14210 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14212 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14214 * nsmenu.m (runDialogAt): Remove argument to timer_check.
14216 2011-03-27 Glenn Morris <rgm@gnu.org>
14218 * syssignal.h: Replace RETSIGTYPE with void.
14219 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
14220 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
14221 Replace SIGTYPE with void everywhere.
14222 * s/usg5-4-common.h (SIGTYPE): Remove definition.
14223 * s/template.h (SIGTYPE): Remove commented out definition.
14225 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14227 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14228 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14230 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14232 * w32.c (read_unc_volume): Use parameter `henum', instead of
14233 global variable `wget_enum_handle'.
14235 * keymap.c (describe_vector): Remove parameters `indices' and
14236 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
14237 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
14239 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
14241 * keyboard.c (timer_check): Remove parameter `do_it_now',
14242 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
14243 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
14244 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
14246 * keyboard.c (read_char):
14247 * w32menu.c (w32_menu_display_help):
14248 * xmenu.c (show_help_event, menu_help_callback):
14249 Adjust calls to `show_help_echo'.
14251 * gtkutil.c (xg_maybe_add_timer):
14252 * keyboard.c (readable_events):
14253 * process.c (wait_reading_process_output):
14254 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14256 * insdel.c (adjust_markers_gap_motion):
14257 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
14258 (gap_left, gap_right): Don't call it.
14260 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

14304 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
14306 * w32term.c (x_set_glyph_string_clipping):
14307 Don't pass uninitialized region to CombineRgn.
14309 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
14311 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
14312 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
14313 (Fx_close_connection): Remove unused variable `i'.
14315 * w32font.c (w32font_draw): Return number of glyphs.
14316 (w32font_open_internal): Remove unused variable `i'.

14329 (uniscribe_font_driver): Add missing initializers.
14331 2011-03-23 Julien Danjou <julien@danjou.info>
14333 * term.c (Fsuspend_tty, Fresume_tty):
14334 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14335 * window.c (temp_output_buffer_show):
14336 * insdel.c (signal_before_change):
14337 * frame.c (Fhandle_switch_frame):
14338 * fileio.c (Fdo_auto_save):
14339 * emacs.c (Fkill_emacs):
14340 * editfns.c (save_excursion_restore):
14341 * cmds.c (internal_self_insert):
14342 * callint.c (Fcall_interactively):
14343 * buffer.c (Fkill_all_local_variables):
14344 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14346 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14347 unconditionally since it does the check itself.
14349 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14351 Fix more problems found by GCC 4.5.2's static checks.
14353 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14354 the first time through the loop, since we know p0 < p1 then.
14355 This also avoids a gcc -Wstrict-overflow warning.
14357 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14358 leading to a memory leak, possible in functions like
14359 load_charset_map_from_file that can allocate an unbounded number
14360 of objects (Bug#8318).
14362 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14363 that could (at least in theory) be that large.
14365 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14366 This is less likely to overflow, and avoids undefined behavior if
14367 overflow does occur. All callers changed. Use strtoul to scan
14368 for the unsigned long integer.
14369 (pint2hrstr): Simplify and tune code slightly.
14370 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14372 * scroll.c (do_scrolling): Work around GCC bug 48228.
14373 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
14375 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
14376 This also avoids a warning with gcc -Wstrict-overflow.
14377 (validate_x_resource_name): Simplify count usage.
14378 This also avoids a warning with gcc -Wstrict-overflow.
14380 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14383 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14385 * process.c (Fmake_network_process): Use socklen_t, not int,
14386 where POSIX says socklen_t is required in portable programs.
14387 This fixes a porting bug on hosts like 64-bit HP-UX, where
14388 socklen_t is wider than int (Bug#8277).
14389 (Fmake_network_process, server_accept_connection):
14390 (wait_reading_process_output, read_process_output):
14393 * process.c: Rename or move locals to avoid shadowing.
14394 (list_processes_1, Fmake_network_process):
14395 (read_process_output_error_handler, exec_sentinel_error_handler):
14396 Rename or move locals.
14397 (Fmake_network_process): Define label "retry_connect" only if needed.
14398 (Fnetwork_interface_info): Fix pointer signedness.
14399 (process_send_signal): Add cast to avoid pointer signedness problem.
14400 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14401 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14403 Make tparam.h and terminfo.c consistent.
14404 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14405 Include tparam.h instead, since it declares them.
14406 * cm.h (PC): Remove extern decl; tparam.h now does this.

14465 clobbering (Bug#8298).
14466 * sysdep.c (sys_subshell): Likewise.
14467 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14469 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14470 This should get cleaned up, so that child_setup has the
14471 same signature on all platforms.
14473 * callproc.c (call_process_cleanup): Now static.
14474 (relocate_fd): Rename locals to avoid shadowing.
14476 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

14635 (Fmemory_limit): Cast sbrk's returned value to char *.
14637 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14645 to use the following functions instead of these macros.
14646 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14647 EMACS_INT, since callers assume the returned value fits in int.
14648 (upcase1): Likewise, for UPCASE_TABLE.
14649 (uppercasep, lowercasep, upcase): New static inline functions.
14650 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14660 (regex_compile, re_match_2_internal): Mark locals as initialized.
14661 (RETALLOC_IF): Define only if needed.
14662 (WORDCHAR_P): Likewise. This one is never needed, but is used
14663 only in a comment talking about a compiler bug, so put inside
14664 the #if 0 of that comment.
14665 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14666 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14693 New macros, so that the caller can use some names other than
14694 gcpro1, gcpro2, etc.
14695 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14697 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14698 argument, for consistency with GCPRO2_VAR, etc: it is now the
14699 prefix of the variable, not the variable itself. All uses
14701 * dired.c (directory_files_internal, file_name_completion):
14702 Rename locals to avoid shadowing.
14704 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14705 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14706 dired.c's scmp function, had undefined behavior.
14707 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14708 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14709 * buffer.h: ... to here, because these macros use current_buffer,
14710 and the new implementation with inline functions needs to have
14711 current_buffer in scope now, rather than later when the macros
14713 (downcase, upcase1): New static inline functions.
14714 (DOWNCASE, UPCASE1): Reimplement using these functions.
14715 This avoids undefined behavior in expressions like
14716 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14717 from race conditions in accessing the global variables
14718 case_temp1 and case_temp2.
14719 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14720 * lisp.h (case_temp1, case_temp2): Remove their decls.
14721 * character.h (ASCII_CHAR_P): Move from here ...
14722 * lisp.h: ... to here, so that the inline functions mentioned
14723 above can use them.

14730 (file_name_as_directory): Use const pointers when appropriate.

14734 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14736 (Fset_file_times, Finsert_file_contents, auto_save_error):

14741 to avoid shadowing.
14743 * marker.c (bytepos_to_charpos): Remove; unused.
14745 * lisp.h (verify_bytepos, count_markers): New decls,
14746 so that gcc does not warn that these functions aren't declared.
14748 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14749 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14750 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14751 (copy_text): Remove unused local var.

14756 * buffer.c (fix_overlays_before): Mark locals as initialized.
14757 (fix_start_end_in_overlays): Likewise. This function should be
14758 simplified by using pointers-to-pointers, but that's a different

14761 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14762 (report_overlay_modification): Rename locals to avoid shadowing.

14767 to suppress a gcc -Wclobbered warning that does not seem to be right.
14768 (MAXPATHLEN): Define only if needed.
14770 * process.c (serial_open, serial_configure): Move decls from here ...
14771 * systty.h: ... to here, so that they can be checked.
14773 * fns.c (get_random, seed_random): Move extern decls from here ...
