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

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

394 Remove unnecessary pointer casts.
395 * alloc.c (record_xmalloc): New function.
396 * lisp.h (record_xmalloc): New decl.
397 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
398 more like a function. This is because the pointer cast is not
399 needed. All uses changed.
400 * print.c (print_string, print_error_message): Avoid length recalc.
402 Improve fix for macroexp crash with debugging (Bug#12118).
403 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
404 ARRAY_MARK_FLAG when checking subscripts, because ASET is
405 not supposed to be invoked from the garbage collector.
406 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
407 (gc_aset): New function, which is like ASET but can be
408 used in the garbage collector.

424 headers (most versions of MinGW w32api don't).
425 (get_security_info, create_symbolic_link)
426 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
428 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
429 in the argument file name.

435 get_file_security_desc.
436 (stat_worker): New function, with most of the guts of 'stat', and
437 with addition of handling of symlinks and support for 'lstat'. If
438 possible, get file's attributes and security information by
439 handle, not by name. Produce S_IFLNK bit for symlinks, when
441 (stat, lstat): New functions, call 'stat_worker'.
442 (symlink, readlink, careadlinkat): Rewritten to create and resolve
443 symlinks when the underlying filesystem supports them.
445 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
447 Fix macroexp crash on Windows with debugging (Bug#12118).
448 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
449 checking subscripts; problem introduced with the recent
450 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
451 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
452 since it's used in non-static inline functions now.
454 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
455 Don't assume buffer size fits in 'int'. Remove unused local.
457 Use C99-style 'extern inline' if available.
458 * buffer.h (BUFFER_INLINE):
459 * category.h (CATEGORY_INLINE):

945 Improve GDB symbol export (Bug#12036).
946 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
947 arms of an 'if', not using conditional expressions; otherwise GDB
948 complains about the types in the unevaluated arm when the argument
949 is an integer literal.
950 (xgetint): Simplify expression.
951 * alloc.c (gdb_make_enums_visible): New constant. This ports to
952 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
953 Zaretskii in <http://bugs.gnu.org/12036#13>.
954 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
955 needed now that we have gdb_make_enums_visible.
956 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
957 (enum enum_USE_LSB_TAG):
958 New enum types, packaging up enums that need to be exported to GDB.
960 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
962 Utility function to make a list from specified amount of objects.
963 * lisp.h (enum constype): New datatype.

976 * xdisp.c (syms_of_xdisp): Likewise.
977 * xfns.c (syms_of_xfns): Likewise.
979 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
981 Fast save_excursion_save and save_excursion_restore.
982 * lisp.h (struct Lisp_Excursion): New data type.
983 (PVEC_EXCURSION): New pseudovector type.
984 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
985 to deal with it. Adjust comments.
986 (init_marker, attach_marker): New prototype.
987 (unchain_marker): Adjust prototype.

996 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
998 Fix export of symbols to GDB (Bug#12036).
999 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
1000 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
1001 emacs.c, as this is a more-suitable home. Had this been done earlier
1002 the fix for 12036 would have avoided some of the problems noted in
1003 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1004 would have been more obvious.
1005 * emacs.c: Do not include <verify.h>; no longer needed.
1006 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
1007 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
1008 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1009 Remove; now done in lisp.h.
1010 * lisp.h (PUBLISH_TO_GDB): New macro.
1011 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
1012 (DATA_SEG_BITS): Use it.
1013 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
1014 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1015 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1016 not be usable in #if. This simplifies things.
1018 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1020 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
1022 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
1024 Simplify export of symbols to GDB (Bug#12036).
1025 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1026 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1027 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1028 Adjust to changes in lisp.h and emacs.c, by using
1029 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1030 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1031 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1032 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1033 instead of gdb_valbits.
1034 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1035 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1036 instead of gdb_array_mark_flag.
1037 (xboolvector): Get size from $->size, not $->header.size.
1038 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1039 (xreload, hook-run, hookpost-run): Remove.
1040 * emacs.c: Include <verify.h>.
1041 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1042 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1044 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1045 (gdb_USE_LSB_TAG): New enum constants.
1046 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1047 Also define these as enum constants, so they're visible to GDB.
1048 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1049 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1050 as constants, so they're visible to GDB.
1051 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
1052 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
1053 Now enum constants, not macros, so they're visible to GDB.
1054 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1055 more convenient now. All uses changed.
1056 (VALMASK) [USE_LSB_TAG]: Also define in this case.
1057 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
1059 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

1066 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
1067 add argument, tune behavior, and adjust all callers.
1069 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1071 Use typedef for EMACS_INT, EMACS_UINT.
1072 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1073 than macros. This simplifies debugging in the usual case, since
1074 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1075 and it allows expressions involving EMACS_INT casts.
1076 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1078 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
1080 * nsterm.m (ns_read_socket): Return early if there is a modal

1086 that FOCUS-FRAME can be omitted.
1088 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
1090 Adjust buffer text indirection counters at the end of Fkill_buffer.
1091 * buffer.c (Fkill_buffer): Adjust indirection counters when the
1092 buffer is definitely dead. This should really fix an issue reported
1093 by Christoph Scholtes again. (Bug#12007).
1094 (init_buffer_once): Initialize indirection counters of
1095 buffer_defaults and buffer_local_symbols (for sanity and safety).
1097 2012-07-24 Eli Zaretskii <eliz@gnu.org>
1099 * xdisp.c (init_iterator): Don't compute dimensions of truncation
1100 and continuation glyphs on tooltip frames, leave them at zero.
1101 Avoids continued lines in tooltips. (Bug#11832)
1103 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
1105 Simplify copy_overlay.

1128 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1130 Swap buffer text indirection counters in Fbuffer_swap_text.
1131 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1132 This avoids crash reported by Christoph Scholtes at
1133 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1135 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1137 * nsmenu.m (Popdown_data): New struct.

1142 and autorelease them. Also autorelease img and matrix (Bug#12005).
1143 (dealloc): Remove (Bug#12005).

1160 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
1162 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
1163 as it's limited by the amount of memory, not by INT_MAX.
1165 2012-07-21 Eli Zaretskii <eliz@gnu.org>
1167 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
1168 in special-event-map. See the discussion at

1227 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
1228 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
1229 Adjust users accordingly.
1230 * font.h (font_open_by_name): Adjust prototype.

1249 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
1250 'for_each_per_buffer_object_at'.
1251 All uses changed. It's better to use upper-case for macros that
1252 cannot be implemented as functions, to give the reader a clue
1253 that they're special.
1255 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
1257 * alloc.c (Fgarbage_collect): Tweak docstring.

1298 * intervals.c (merge_interval_right, merge_interval_left):
1299 Do not zero out this interval if it is absorbed by its children,
1300 as this interval's total length doesn't change in that case. See
1301 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
1303 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
1305 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
1306 when invoking (make-bool-vector N t) and N is a positive

1310 * alloc.c (bool_header_size): New constant.
1311 (header_size, word_size): Move earlier, as they're now used earlier.

1314 padding before the data member of a bool vector.
1315 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
1316 than doing the check by hand with an abort ().
1318 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1320 * eval.c (Fdefvar): Don't check constants since we only set the var if
1321 it's not yet defined anyway (bug#11904).
1323 * lisp.h (last_undo_boundary): Declare new var.
1324 * keyboard.c (command_loop_1): Set it.
1325 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
1326 were auto-added by the command loop (bug#11774).
1328 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
1330 * w32font.c (Qsymbol): Remove local definition.

1833 * s/gnu.h, s/gnu-linux.h:
1834 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
1836 2012-07-11 John Wiegley <johnw@newartisans.com>
1838 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
1839 function attribute, so we only use it if it exists in the
1842 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
1844 Avoid call to strlen in fast_c_string_match_ignore_case.
1845 * search.c (fast_c_string_match_ignore_case): Change to use
1846 length argument. Adjust users accordingly.
1847 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
1849 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

1891 * s/aix4-2.h (unix): Remove; no longer needed.
1893 EMACS_TIME simplification (Bug#11875).
1894 This replaces macros (which typically do not work in GDB)
1895 with functions, typedefs and enums, making the code easier to debug.
1896 The functional style also makes code easier to read and maintain.
1897 * systime.h: Include <sys/time.h> on all hosts, not just if
1898 WINDOWSNT, since 'struct timeval' is needed in general.
1899 (EMACS_TIME): Now a typedef, not a macro.
1900 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
1902 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

1905 (EMACS_TIME_LE): Now functions, not macros.
1906 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
1907 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1908 which are not functions. All uses rewritten to use:
1909 (make_emacs_time): New function.
1910 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1911 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1912 not functions. All uses rewritten to use the following, respectively:
1913 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1914 (add_emacs_time, sub_emacs_time): New functions.
1915 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1916 * fileio.c (Fcopy_file):
1917 * xterm.c (XTflash): Get the current time closer to when it's used.
1918 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1925 * frame.c (Fmake_terminal_frame):
1926 * gtkutil.c (get_utf8_string):
1928 * nsmenu.m (ns_update_menubar):
1929 * regex.c (regerror):
1930 Prefer memcpy to strncpy and strncat when either will do.
1931 * fileio.c (Fsubstitute_in_file_name):
1932 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1933 (menu_separator_name_p):
1934 * nsmenu.m (ns_update_menubar):
1935 Prefer memcmp to strncmp when either will do.
1936 * nsterm.m: Include <ftoastr.h>.
1938 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1939 Prefer snprintf to strncpy.
1940 * nsterm.m (ns_term_init):
1941 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1942 * nsterm.m (ns_term_init):
1943 Avoid the need for strncpy, by using build_string or
1944 make_unibyte_string directly. Use dtoastr, not snprintf.
1945 * process.c (Fmake_network_process): Diagnose service names that
1946 are too long, rather than silently truncating them or creating
1947 non-null-terminated names.
1948 (Fnetwork_interface_info): Likewise, for interface names.
1949 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1950 Prefer sprintf to strncat.
1951 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1952 Prefer vsnprintf to vsprintf + strncpy.
1954 2012-07-10 Glenn Morris <rgm@gnu.org>
1956 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1957 Clarify fallback case.
1959 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1961 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1962 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1963 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1964 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1965 where argument type is known to be a Lisp_Cons.

1975 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1977 Optimize pure C strings initialization.
1978 * lisp.h (make_pure_string): Fix prototype.
1979 (build_pure_c_string): New function, defined as static inline. This
1980 provides a better opportunity to optimize away calls to strlen when
1981 the function is called with compile-time constant argument.
1982 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1983 argument, adjust users accordingly. Use build_pure_c_string where
1985 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1986 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1987 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1989 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1991 Avoid calls to strlen in miscellaneous functions.
1992 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1993 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1994 * lread.c (openp): Likewise.
1996 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1998 Avoid calls to strlen in path processing functions.
1999 * fileio.c (file_name_as_directory): Add comment. Change to add
2000 srclen argument and return the length of result. Adjust users
2002 (directory_file_name): Fix comment. Change to add srclen argument,
2003 swap 1st and 2nd arguments to obey the common convention. Adjust
2005 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2007 2012-07-10 Glenn Morris <rgm@gnu.org>
2009 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
2010 Move PENDING_OUTPUT_COUNT definition to configure.
2012 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
2013 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
2014 * s/gnu.h (DATA_START): Move definitions to configure.
2016 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2017 We include usg5-4-common.h, which defines them both.
2019 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2020 O_RDONLY already includes it).
2022 Stop ns builds setting the EMACSLOADPATH environment variable.
2023 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2024 Now it does not set EMACSLOADPATH, just returns the load-path string.
2025 * nsterm.h: Update accordingly.
2026 * lread.c [HAVE_NS]: Include nsterm.h.
2027 (init_lread) [HAVE_NS]: Use ns_load_path.
2028 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
2030 2012-07-09 Glenn Morris <rgm@gnu.org>
2032 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2033 since the included bsd-common.h does so.
2035 Stop ns builds setting the EMACSPATH environment variable.
2036 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2037 (ns_init_paths): Do not set EMACSPATH.
2038 * nsterm.h (ns_exec_path): Add it.
2039 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2042 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2044 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2046 * process.c (wait_reading_process_output): 'waitchannels' was unset
2047 when read_kbd || !NILP (wait_for_cell); fix this.
2049 Add GCC-style 'const' attribute to functions that can use it.
2050 * character.h (char_resolve_modifier_mask):
2051 * keyboard.h (make_ctrl_char):
2052 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
2053 (init_character_once, next_almost_prime, init_fns, init_image)
2054 (flush_pending_output, init_sound):
2055 * mem-limits.h (start_of_data):
2056 * menu.h (finish_menu_items):

2059 Declare the dummy function with ATTRIBUTE_CONST.
2060 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2061 Add decls with ATTRIBUTE_CONST.
2063 Minor improvements to make_formatted_string.
2064 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2065 where int is good enough, as vsprintf returns an int.
2066 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2068 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2070 Use make_formatted_string to avoid double length calculation.
2071 * lisp.h (make_formatted_string): New prototype.
2072 * alloc.c (make_formatted_string): New function.
2073 * buffer.c (Fgenerate_new_buffer_name): Use it.
2074 * dbus.c (syms_of_dbusbind): Likewise.

2077 * frame.c (make_terminal_frame, set_term_frame_name)
2078 (x_report_frame_params): Likewise.
2079 * image.c (gs_load): Likewise.
2080 * minibuf.c (get_minibuffer): Likewise.

2095 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2097 Move marker debugging code under MARKER_DEBUG.
2098 * marker.c (MARKER_DEBUG): Move marker debugging code under
2099 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2100 for bootstrap with --enable-checking (~3x slowdown reported
2101 by Juanma Barranquero <lekktu@gmail.com>).
2102 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2104 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2106 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2107 See <http://bugs.gnu.org/11825#29>.
2109 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2111 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2112 has no font, use the frame's font. (Bug#11813)
2113 (display_line): Add commentary about displaying truncation glyphs
2115 (produce_special_glyphs): Move here from term.c.
2117 * term.c (produce_special_glyphs): Move to xdisp.c.
2119 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2122 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2124 * xdisp.c (display_line): Avoid warning about implicit declaration
2127 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2129 * lisp.h: Remove empty conditional.
2131 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2133 * lread.c (load_path_check): Now static.
2135 Fix some minor --with-ns problems found by static checking.
2136 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2137 (x_set_font) [!HAVE_X_WINDOWS]:
2138 * image.c (xpm_load_image) [HAVE_NS]:
2139 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2140 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2141 Remove unused local.
2142 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2143 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2144 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2145 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2146 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2147 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2148 Fix pointer signedness problem.
2149 * xfaces.c (FRAME_X_FONT_TABLE):
2150 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2152 2012-07-07 Glenn Morris <rgm@gnu.org>
2154 * lread.c (load_path_check): New function, split from init_lread.
2155 (init_lread): Reorganize. Motivation:
2156 If EMACSLOADPATH is set, check/warn about that rather than the
2157 defaults, which we are not going to use. Hence we can remove
2158 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2159 Don't warn if site-lisp directories are missing.
2160 If not installed, start from a blank load-path, since
2161 PATH_LOADSEARCH refers to the eventual installation directories.
2163 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2165 Support truncation and continuation glyphs on GUI frames, when
2166 fringes are disabled. (Bug#11832)
2167 * xdisp.c (init_iterator): Get dimensions of truncation and
2168 continuation glyphs even if on GUI frames. Adjust
2169 it->last_visible_x on GUI frames when the left or right fringes,
2170 or both, are absent.
2171 (start_display, move_it_in_display_line_to): Handle the case of a
2172 GUI frame without a fringe to display continuation or truncation
2174 (insert_left_trunc_glyphs): Support GUI frames: make sure
2175 truncation glyphs overwrite enough glyphs from the current line to
2176 have sufficient space in pixels.
2177 (display_line): Support truncation and continuation glyphs on GUI
2178 frames. If some spare pixels are left on the line after inserting
2179 the truncation glyphs, fill that space with a stretch glyph of a
2180 suitably computed width.
2182 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2183 produce_glyphs, to support GUI sessions.
2185 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2187 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2189 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2191 Do not require float-time's arg to fit in time_t (Bug#11825).
2192 This works better on hosts where time_t is unsigned, and where
2193 float-time is applied to the (negative) difference between two times.
2194 * editfns.c (decode_time_components): Last arg is now double *,
2195 not int *, and means to store all the result as a double, without
2196 worrying about whether the seconds part fits in time_t.
2197 All callers changed.
2198 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2199 All callers changed.
2200 (Ffloat_time): Do not fail merely because the specified time falls
2201 outside of time_t range.
2203 2012-07-07 Glenn Morris <rgm@gnu.org>
2205 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
2206 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

2209 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2211 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2212 Update dependencies.
2214 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2216 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2218 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
2219 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
2220 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2221 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2222 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2223 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2225 * xfont.c (compare_font_names): Redo to omit the need for casts.
2227 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2229 * xfns.c (Fx_change_window_property): Doc fix.
2230 * w32fns.c (Fx_change_window_property): Doc fix.
2232 * w32fns.c (Fx_window_property): Accept the same arguments as the
2233 X Windows version. Doc fix.
2234 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2236 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2237 Eli Zaretskii <eliz@gnu.org>
2239 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2240 Windows-specific code from nt/config.nt moved here.
2241 Obsolete settings removed.
2243 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2245 * process.c: Avoid unnecessary calls to gettime.
2246 (wait_reading_process_output): Don't get the time of day
2247 when gobbling data immediately and not waiting, as there's no need
2248 for it in that case. This removes a FIXME.
2250 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2252 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2253 is defined (Bug#11768).
2255 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2257 Fix marker debugging code.
2258 * marker.c (byte_char_debug_check): Do not perform the check
2259 if buffer is not multibyte.
2260 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2261 Call byte_char_debug_check with correct arguments.
2263 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2265 Compile marker debugging code only if ENABLE_CHECKING is defined.
2266 * marker.c (byte_char_debug_check, count_markers):
2267 Use only if ENABLE_CHECKING is defined.
2268 (byte_debug_flag): Remove.
2269 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2270 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2272 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2274 Avoid code repetition in marker-related functions.
2275 * marker.c (attach_marker): New function.
2276 (Fset_marker, set_marker_restricted, set_marker_both)
2277 (set_marker_restricted_both): Use it.
2278 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2279 Consistently rename charno to charpos.
2280 (marker_position): Add eassert.
2281 (marker_byte_position): Convert to eassert.
2283 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2285 Simplify list operations in unchain_overlay and unchain_marker.
2286 * buffer.c (unchain_overlay): Simplify. Add comment.
2287 * marker.c (unchain_marker): Simplify. Fix comments.
2289 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2291 Introduce fast path for the widely used marker operation.
2292 * alloc.c (build_marker): New function.
2293 * lisp.h (build_marker): New prototype.
2294 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
2295 * composite.c (autocmp_chars): Likewise.
2296 * editfns.c (buildmark): Remove.
2297 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2298 (save_restriction_save): Use build_marker.
2299 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2300 * window.c (save_window_save): Likewise.
2302 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2304 Do not use Fdelete_overlay in delete_all_overlays
2305 to avoid redundant calls to unchain_overlay.
2306 * buffer.c (drop_overlay): New function.
2307 (delete_all_overlays, Fdelete_overlay): Use it.
2308 * minibuf.c (get_minibuffer): Fix comment.
2310 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2312 Port to OpenBSD 5.1 amd64.
2313 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2314 This is needed for OpenBSD, and should be harmless on all BSD systems.
2315 Also, include <sys/sysctl.h>, as it should be available on all
2316 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2317 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2318 use p_pid member, not kp_proc.pid.
2320 2012-07-06 Glenn Morris <rgm@gnu.org>
2322 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2324 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2326 More xmalloc and related cleanup.
2327 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

2333 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2334 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2335 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2337 Omit needless casts involving void * pointers and allocation.
2338 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2339 as the former is more robust if P's type is changed.
2340 Prefer xzalloc to xmalloc + memset 0.
2341 Simplify malloc-or-realloc to realloc.
2342 Don't worry about xmalloc returning a null pointer.
2343 Prefer xstrdup to xmalloc + strcpy.
2344 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2346 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2347 alloca of a constant.
2349 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2351 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2352 hscroll is larger than the line width. Fixes long and futile
2353 looping inside extend_face_to_end_of_line (on a TTY) producing
2354 glyphs that are not needed and thrown away.
2356 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2358 * marker.c (set_marker_restricted_both): Simplify by using
2361 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2363 * editfns.c (region_limit): Simplify by using clip_to_bounds.
2365 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
2367 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
2368 not defined (Bug#11768).
2369 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2370 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2371 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2372 followed by gtk_box_set_homogeneous (Bug#11768).
2373 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2374 (update_theme_scrollbar_width, xg_create_scroll_bar):
2375 Use gtk_scrollbar_new (Bug#11768).
2376 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2377 (is_box_type): New function (Bug#11768).
2378 (xg_tool_item_stale_p): Call is_box_type.
2379 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2380 with default display (Bug#11768).
2382 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2384 * xdisp.c (window_hscroll_limited): New function.
2385 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2386 coordinates when window's hscroll is set to insanely large
2389 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2391 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2392 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2394 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2397 * lisp.h (xzalloc): New prototype. Omit needless casts.
2398 * alloc.c (xzalloc): New function. Omit needless casts.

2450 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2452 * fileio.c (time_error_value): Check the right error number.
2453 Problem reported by Troels Nielsen in
2454 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2456 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2458 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2459 This should be fixed in a better way; see Eli Zaretskii in
2460 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2461 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2463 * fileio.c (time_error_value): Rename from special_mtime.
2464 The old name's problems were noted by Eli Zaretskii in
2465 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2467 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2468 This variable's comment says Emacs needs at least one GDB-visible
2469 symbol of type enum pvec_type, to work around GDB problems.
2470 The symbol's value doesn't matter.
2472 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2473 that causes compilation to fail on pre-C99 compilers.
2475 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2477 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2478 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2480 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2482 * buffer.c (init_buffer_once): Fix initialization of
2483 headers for buffer_defaults and buffer_local_symbols.
2484 Reported by Juanma Barranquero <lekktu@gmail.com>.
2486 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2488 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2489 * lisp.h (enum pvec_type): Use fewer bits.
2490 (PSEUDOVECTOR_SIZE_BITS): New constant.
2491 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2492 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2493 change in pvec_type.
2494 (PSEUDOVECTOR_TYPEP): New macro.
2495 (TYPED_PSEUDOVECTORP): Use it.
2496 * fns.c (internal_equal): Adapt code to extract pvectype.
2497 * emacs.c (gdb_pvec_type): Update type.
2498 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2499 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2500 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2501 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2502 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2503 abusing vector->header.next.nbytes.
2504 (live_vector_p): Use PVEC_TYPE.
2505 (mark_object): Adapt code to extract pvectype. Use switch.
2507 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2509 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2510 Tighten new eassert a bit.
2512 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2514 Fix compilation with --enable-gcc-warnings and -O1
2516 * doprnt.c (doprnt): Change type of tem to int, initialize
2517 to avoid compiler warning. Add eassert.
2518 * search.c (simple_search): Initialize match_byte to avoid
2519 compiler warning. Add eassert.
2521 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2523 Avoid weird behavior with large horizontal scrolls.
2524 Without this change, for example, large hscroll values would
2525 mess up Emacs's display on Fedora 15 x86, presumably due to
2526 overflows in int calculations in the display code.
2527 Also, if buffers had long lines, Emacs would freeze.
2528 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2529 (set_window_hscroll): New function, containing the old guts of
2530 Fset_window_hscroll. Return the clipped value.
2531 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2532 This avoids the need to check against PTRDIFF_MAX.
2534 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2536 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2538 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2540 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2542 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2543 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2544 since GCC 4.4.6 issues a bogus warning for them.
2546 Fix bugs in file timestamp newness comparisons.
2547 * fileio.c (Ffile_newer_than_file_p):
2548 * lread.c (Fload): Use full timestamp resolution of files,
2549 not just the 1-second resolution, so that files that are only
2550 slightly newer still count as newer.
2551 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2552 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2554 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2556 * fileio.c: Improve handling of file time marker. (Bug#11852)
2557 (special_mtime): New function.
2558 (Finsert_file_contents, Fverify_visited_file_modtime):
2559 Use it to set special mtime values consistently.
2561 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2563 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2564 marker for non-existing file. (Bug#11852)
2566 2012-07-03 Glenn Morris <rgm@gnu.org>
2568 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2569 and did not make it into globals.h).
2571 2012-07-03 Tom Tromey <tromey@redhat.com>
2573 * window.c (Fset_window_margins, Fset_window_fringes)
2574 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2575 * textprop.c (Fprevious_property_change): No longer static.
2576 * syntax.c (Fsyntax_table_p): No longer static.
2577 * process.c (Fget_process, Fprocess_datagram_address): No longer

2592 * composite.c (Fcomposition_get_gstring): No longer static.
2593 * callproc.c (Fgetenv_internal): No longer static.
2595 * ccl.h: Remove EXFUNs.
2596 * buffer.h: Remove EXFUNs.
2597 * dispextern.h: Remove EXFUNs.
2598 * intervals.h: Remove EXFUNs.
2599 * fontset.h: Remove EXFUN.
2600 * font.h: Remove EXFUNs.
2601 * dosfns.c (system_process_attributes): Remove EXFUN.
2602 * keymap.h: Remove EXFUNs.
2603 * lisp.h: Remove EXFUNs.
2604 * w32term.h: Remove EXFUNs.
2605 * window.h: Remove EXFUNs.
2606 * xsettings.h: Remove EXFUN.
2607 * xterm.h: Remove EXFUN.
2609 2012-07-03 Glenn Morris <rgm@gnu.org>
2611 * lisp.h (Frandom): Make it visible to C.
2612 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2613 buffer for invisible buffers. (Bug#1229)
2615 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2617 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2618 values which aren't power of 2.
2619 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2620 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2623 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2625 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2627 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2629 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2631 * alloc.c (allocate_vector_block): Remove redundant
2632 calls to mallopt if DOUG_LEA_MALLOC is defined.
2633 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2634 avoid calls to mallopt if zero_vector is returned.
2636 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2638 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2639 is enabled, avoid dereferencing NULL current_sblock if
2642 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2644 Cleanup basic buffer management.
2645 * buffer.h (struct buffer): Change layout to use generic vector
2646 marking code. Fix some comments. Change type of 'clip_changed'
2647 to bitfield. Remove unused #ifndef old.
2648 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2649 (GET_OVERLAYS_AT): Fix indentation.
2650 (for_each_per_buffer_object_at): New macro.
2651 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2652 (Fbuffer_local_variables): Use it.
2653 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2654 * alloc.c (allocate_buffer): Adjust to match new layout of
2655 struct buffer. Fix comment.
2656 (mark_overlay): New function.
2657 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2658 Lisp area of struct buffer.
2659 (mark_object): Use it. Adjust marking of misc objects
2660 and related comments.
2662 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2664 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2665 wrapper that is not needed because the wrapped code is a no-op (zero
2666 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2667 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2669 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2671 * alloc.c (mark_buffer): Simplify. Remove prototype.
2672 (mark_object): Add comment. Reorganize marking of vector-like
2673 objects. Use CHECK_LIVE for all vector-like objects except buffers
2674 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2675 redundant calls to mark_vectorlike for bool vectors.
2677 2012-06-30 Glenn Morris <rgm@gnu.org>
2679 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2681 * epaths.in (PATH_SITELOADSEARCH): New.
2682 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2683 This is rather than relying on --enable-locallisppath elements
2684 having "site-lisp" in their names. (Bug#10208#25, 11658)
2686 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2688 * w32proc.c (sys_select): Accept and ignore one more argument.
2690 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2692 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2693 (pselect) [!MS_DOS]: Redirect to sys_select.
2695 * sysdep.c: Don't include dos.h and dosfns.h.
2697 * process.c (sys_select):
2698 * msdos.c (sys_select): Accept one more argument and ignore it.
2700 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2701 adapt data types and code to that.
2704 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2705 which clashes with the gnulib function of the same name.
2707 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2709 * font.c (font_style_to_value, font_style_symbolic)
2710 (font_prop_validate_style): Add type checks for values in
2713 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2715 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2718 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2720 * xdisp.c (try_window_id): Undo last change.
2722 * w32.c (getwd): Adjust commentary about startup_dir.
2723 (init_environment): Always call sys_access, even in non-MSVC
2724 builds. Don't chdir to the directory of the Emacs executable.
2725 This undoes code from 1997 which was justified by the need to
2726 "avoid conflicts when removing and renaming directories". But its
2727 downside was that every relative file name was being interpreted
2728 relative to the directory of the Emacs executable, which can never
2729 be TRT. In particular, it broke sys_access when called with
2730 relative file names.
2731 (sys_access): Map GetLastError to errno.
2733 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2735 * window.h (struct window): Change type of 'fringes_outside_margins'
2736 to bitfield. Fix comment. Adjust users accordingly.
2737 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2739 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2742 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2744 * gnutls.c (emacs_gnutls_handshake):
2745 Add QUIT to make the loop interruptible.
2747 2012-06-29 Glenn Morris <rgm@gnu.org>
2749 * charset.c (init_charset): Make lack of etc/charsets fatal.
2751 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2753 * editfns.c (region_limit): Fix type mismatch.
2755 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

2923 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2925 Use sprintf return value instead of invoking strlen on result.
2926 In the old days this wasn't portable, since some sprintf
2927 implementations returned char *. But they died out years ago and
2928 Emacs already assumes sprintf returns int.
2929 Similarly for float_to_string.
2930 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2938 Use sprintf or float_to_string result to avoid need to call strlen.
2939 * data.c (Fnumber_to_string):
2940 Use make_unibyte_string, since the string must be ASCII.
2941 * lisp.h, print.c (float_to_string): Now returns int length.
2942 * term.c (produce_glyphless_glyph):
2943 Use sprintf result rather than recomputing it.
2945 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2946 * Makefile.in (ALL_CFLAGS):
2947 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2976 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2978 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2981 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2983 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2984 instead of truncating it to 63 (admittedly a generous limit).

3044 * keyboard.c (kbd_buffer_get_event):
3045 * process.c (Faccept_process_output):
3046 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3047 This improves on the previous patch, which introduced a bug
3048 when time_t is unsigned and as wide as intmax_t.
3049 See <http://bugs.gnu.org/9000#51>.
3051 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3114 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3116 Support higher-resolution time stamps (Bug#9000).
3117 The time stamps are only nanosecond-resolution at the C level,
3118 since that's the best that any real-world system supports now.
3119 But they are picosecond-resolution at the Lisp level, as that's
3120 easy, and leaves room for future OS improvements.
3122 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3125 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3126 Don't get current time unless it's needed.
3128 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3129 now provides it if it's absent.
3130 (start_atimer): Port to higher-res time stamps.
3131 Check for time stamp overflow. Don't get current time more
3132 often than is needed.
3134 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3135 Include systime.h, not time.h.
3136 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3138 * dired.c: Include stat-time.h.
3139 (Ffile-attributes): File times now have higher resolution.

3142 (struct image): Timestamp now has higher resolution.
3144 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3145 has at least microseconds now. All uses removed.
3146 (update_frame, update_single_window, update_window, update_frame_1)
3147 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3149 * editfns.c (time_overflow): Now extern.
3150 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3151 (float-time, Fformat_time_string, Fcurrent_time_string)
3152 (Fcurrent_time_zone): Accept and generate higher-resolution

3155 (decode_time_components, lisp_seconds_argument): New functions.
3156 (make_time): Now static.
3157 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3158 Report an error if the time is invalid, rather than having the caller
3161 * fileio.c: Include <stat-time.h>
3162 (Fcopy_file): Copy higher-resolution time stamps.
3163 Prefer to set the time stamp via a file descriptor if that works.
3164 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3165 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3166 (Fvisited_file_modtime, Fset_visited_file_modtime):
3167 Support higher-resolution time stamps.
3169 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3171 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3173 * image.c (prepare_image_for_display, clear_image_cache)
3174 (lookup_image): Port to higer-resolution time stamps.
3176 * keyboard.c (start_polling, bind_polling_period):
3177 Check for time stamp overflow.
3178 (read_char, kbd_buffer_get_event, timer_start_idle)
3179 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3180 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3181 Port to higher-resolution time stamps. Do not assume time_t is signed.
3182 (decode_timer): New function. Timers are now vectors of length 9,
3183 not 8, to accommodate the picosecond component.
3184 (timer_check_2): Use it.
3186 * nsterm.m (select_timeout, timeval_subtract): Remove.
3187 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3188 as they're a bit more accurate and handle overflow better.
3189 (ns_select): Change prototype to be compatible with pselect.
3190 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3191 * nsterm.h (ns_select): Adjust prototype.
3193 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3194 us-resolution time stamps.
3195 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3197 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3199 * lisp.h (time_overflow): New decl.
3200 (wait_reading_process_output): First arg is now intmax_t, not int,
3201 to accommodate larger waits.
3203 * process.h (struct Lisp_Process.read_output_delay):
3204 Now counts nanoseconds, not microseconds.
3205 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3207 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3208 (wait_reading_process_output):
3209 Port to ns-resolution time stamps.
3210 (Faccept_process_output, wait_reading_process_output):
3211 Check for time stamp overflow. Do not assume time_t is signed.
3212 (select_wrapper): Remove; we now use pselect.
3213 (Fprocess_attributes): Now generates ns-resolution time stamps.
3215 * sysdep.c: Include utimens.h. Don't include utime.h
3216 or worry about struct utimbuf; gnulib does that for us now.
3217 (gettimeofday): Remove; gnulib provides a substitute.
3218 (make_timeval): New function.
3219 (set_file_times): Now sets ns-resolution time stamps.
3220 New arg FD; all uses changed.
3221 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3222 (system_process_attributes):
3223 Now returns ns-resolution time stamp. All uses changed.
3224 Check for time stamp overflow.
3226 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3227 provides a substitute now.
3229 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3230 since it guarantees struct timespec.
3231 (EMACS_TIME): Now struct timespec, so that we can support
3232 ns-resolution time stamps.
3233 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3234 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3235 (EMACS_USECS): Remove.
3236 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3237 so multiply the arg by 1000 before storing it.
3238 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3240 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3241 Port to ns-resolution time stamps.
3242 (EMACS_TIME_NEG_P): Remove; replaced by....
3243 (EMACS_TIME_SIGN): New macro.

3247 (make_timeval, make_lisp_time, decode_time_components): New decls.
3248 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

3250 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3251 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

3290 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3291 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

3343 gets killed during executing of this function (Bug#11665).
3344 Try to always return Qt when the buffer has been actually killed.

3346 run by this hook should not change the current buffer.
3348 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

3713 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3714 would mishandle a string argument "Xc" if X was a multibyte
3715 character of length 2: it would truncate after X's first byte
3716 rather than including all of X.
3718 2012-06-06 Chong Yidong <cyd@gnu.org>
3720 * buffer.c (word_wrap): Doc fix.
3722 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
3724 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.
3726 2012-06-03 Glenn Morris <rgm@gnu.org>

3733 (temacs$(EXEEXT)): Disable memory randomization for the temacs
3734 binary via PaX flags if the paxctl utility is available.
3735 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3736 Restore PaX flags to their default. (Bug#11398)
3738 2012-06-03 Chong Yidong <cyd@gnu.org>
3740 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
3743 2012-06-03 Chong Yidong <cyd@gnu.org>
3745 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
3746 (note_mode_line_or_margin_highlight): If there is no help echo,
3747 use mode-line-default-help-echo. Handle the case where the mouse
3748 position is past the end of the mode line string.
3750 * buffer.c (buffer_local_value_1): New function, split from
3751 Fbuffer_local_value; can return Qunbound.
3752 (Fbuffer_local_value): Use it.
3753 (Vmode_line_format): Docstring tweaks.
3755 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
3757 * sysdep.c (system_process_attributes): Improve comment.
3759 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
3761 * keyboard.c: Export real-this-command to Elisp.
3762 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
3763 and DEFVAR it. Update all users.
3765 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
3767 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3769 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3770 Convert pctcpu and pctmem to Lisp float properly.
3771 Let the compiler fold better, as 100.0/0x8000 is exact.
3773 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3775 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3778 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3780 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3782 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3784 For a 'struct window', replace some Lisp_Object fields to
3785 bitfields where appropriate, remove unused fields.
3786 * window.h (struct window): Remove unused 'last_mark_x' and
3787 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3788 change it's type from Lisp_Object to bitfield.
3789 Change type of 'force_start', 'optional_new_start',
3790 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3791 fields from Lisp_Object to bitfield. Adjust users accordingly.
3793 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3795 Pacify gcc -Wdouble-precision when using Xaw.
3796 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3797 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3798 Use 'float' consistently, rather than 'float' in most places
3799 and 'double' in a couple of places.
3801 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3803 * xdisp.c (handle_stop): Detect whether we have overlay strings
3804 loaded by testing it->current.overlay_string_index to be
3805 non-negative, instead of checking whether n_overlay_strings is
3806 positive. (Bug#11587)
3808 2012-05-31 Chong Yidong <cyd@gnu.org>
3810 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3812 * doc.c (Fsubstitute_command_keys): Doc fix.
3814 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3816 * search.c (search_buffer): Remove calls to
3817 r_alloc_inhibit_buffer_relocation, as it is now called by
3818 maybe_unify_char, which was the cause of relocation of buffer text
3821 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3823 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3824 for the duration of call to load_charset, to avoid problems with
3825 callers of maybe_unify_char that access buffer text through C
3828 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3829 decrement the inhibition flag, instead of just setting or
3832 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3834 Remove obsolete '#define static' cruft.
3835 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3836 This #undef was "temporary" in 2000; it is no longer needed
3837 now that '#define static' has gone away.
3838 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3839 (gray_bitmap_bits): Remove; no longer needed.
3840 All uses replaced with definiens.
3841 * xterm.c: Include "bitmaps/gray.xbm".
3843 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3845 Clean up __executable_start, monstartup when --enable-profiling.
3846 The following changes affect the code only when profiling.
3847 * dispnew.c (__executable_start): Rename from safe_bcopy.
3848 Define only on platforms that need it.
3849 * emacs.c: Include <sys/gmon.h> when profiling.
3850 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3851 (__executable_start): Remove decl, since lisp.h does it now.
3852 (safe_bcopy): Remove decl; no longer has that name.
3853 (main): Coalesce #if into single bit of code, for simplicity.
3854 Cast pointers to uintptr_t, since standard libraries want integers
3856 * lisp.h (__executable_start): New decl.
3858 2012-05-31 Glenn Morris <rgm@gnu.org>
3860 * image.c (Fimagemagick_types): Doc fix.
3862 2012-05-30 Jim Meyering <meyering@redhat.com>
3864 * callproc.c (Fcall_process_region): Include directory component
3865 in mkstemp error message (Bug#11586).
3867 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3869 * alloc.c, lisp.h (make_pure_vector): Now static.
3871 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

3874 Move to byte-run.el.
3875 (Fautoload): Do the hash-doc more carefully.
3876 * data.c (Fdefalias): Purify definition, except for keymaps.
3877 (Qdefun): Move from eval.c.
3878 * lisp.h (Qdefun): Remove.
3879 * lread.c (read1): Tiny simplification.
3881 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3883 Do not create empty overlays with the evaporate property (Bug#9642).
3884 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3885 Bug#9642, but explicitly check that the buffer the overlay would
3886 be moved to is live and rearrange lines to make sure that errors
3887 will not put the overlay in an inconsistent state.
3888 (Fdelete_overlay): Cosmetics.
3890 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3892 * w32term.c (my_bring_window_to_top): New function.
3893 (x_raise_frame): Use handle returned by DeferWindowPos, which
3894 could be different from the original one.
3895 Call my_bring_window_to_top instead of my_set_foreground_window.
3898 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3899 by calling BringWindowToTop.
3901 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3902 (WM_EMACS_END): Increase by one.
3904 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3906 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3907 This avoids undefined behavior that might cause the eassert
3908 to not catch an out-of-range value.
3910 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3912 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3913 Update dependencies.
3915 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3917 * bidi.c (bidi_mirror_char): Fix last change.
3919 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3921 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3922 when referring to sectname field in printf format.
3924 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3926 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3927 Only r_alloc_inhibit_buffer_relocation needed to be added;
3928 the others were already declared.
3930 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3931 before checking whether it's out of range. Put the check inside
3933 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3935 2012-05-27 Ken Brown <kbrown@cornell.edu>
3937 * callproc.c (Fcall_process): Restore a line that was accidentally
3938 commented out in the 2011-02-13 change (bug#11547).
3940 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3942 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3943 defined on ralloc.c.
3945 * buffer.c [REL_ALLOC]: Remove prototypes of
3946 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3947 they are now on lisp.h.
3949 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3951 * search.c (search_buffer): Use it to inhibit relocation of buffer
3952 text while re_search_2 is doing its job, because re_search_2 is
3953 passed C pointers to buffer text. (Bug#11519)
3955 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3958 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3959 state after an additional call to move_it_in_display_line_to, keep
3960 the values of it->max_ascent and it->max_descent found for the
3962 (pos_visible_p): Revert the comparison against bottom_y to what it
3963 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3966 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3968 Fix coding-related core dumps with gcc -ftrapv.
3969 The code was computing A - B, where A and B are pointers, and B is
3970 random garbage. This can lead to core dumps on platforms that
3971 have special pointer registers, and it also leads to core dumps on
3972 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3973 A - B only when B is initialized properly.
3974 * coding.c (coding_set_source, coding_set_destination): Return void.
3975 (coding_change_source, coding_change_destinations): New functions,
3976 with the old behaviors of coding_set_source and coding_set_destination.
3977 All callers that need an offset changed to use these new functions.
3979 2012-05-26 Glenn Morris <rgm@gnu.org>
3981 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3983 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3985 Extend mouse support on W32 text-mode console.
3986 * xdisp.c (draw_row_with_mouse_face):
3987 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3989 * w32console.c: Include window.h.
3990 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3992 (initialize_w32_display): Initialize mouse-highlight data.
3994 * w32inevt.c: Include termchar.h and window.h.
3995 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3996 moves, call note_mouse_highlight. If help_echo changed, call
3997 gen_help_event to produce help-echo message in the echo area.
3998 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4001 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4003 * lread.c (read1): Simplify slightly to avoid an overflow warning
4004 with GCC 4.7.0 on x86-64.
4006 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4008 * bidi.c (bidi_mirror_char): Revert last change: an int is
4009 definitely wide enough here.
4011 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4013 Fix integer width and related bugs (Bug#9874).
4014 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4015 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4016 (string_bytes, check_sblock, allocate_string_data):
4017 (compact_small_strings, Fmake_bool_vector, make_string)
4018 (make_unibyte_string, make_multibyte_string)
4019 (make_string_from_bytes, make_specified_string)
4020 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
4021 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4023 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4024 (allocate_pseudovector):
4025 Use int, not EMACS_INT, where int is wide enough.
4026 (inhibit_garbage_collection, Fgarbage_collect):
4027 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4028 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4029 int might not be wide enough.
4030 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4031 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4032 (bidi_at_paragraph_end, bidi_find_paragraph_start)
4033 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4034 (bidi_level_of_next_char, bidi_move_to_visually_next):
4035 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4036 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4037 (Fkill_buffer, Fset_buffer_major_mode)
4038 (advance_to_char_boundary, Fbuffer_swap_text)
4039 (Fset_buffer_multibyte, overlays_at, overlays_in)
4040 (overlay_touches_p, struct sortvec, record_overlay_string)
4041 (overlay_strings, recenter_overlay_lists)
4042 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4043 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4044 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4045 (Foverlay_recenter, last_overlay_modification_hooks_used)
4046 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4047 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4048 (validate_region): Omit unnecessary test for b <= e,
4049 since that's guaranteed by the previous test.
4050 (adjust_overlays_for_delete): Avoid pos + length overflow.
4051 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4052 (report_overlay_modification):
4053 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4054 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4055 Omit pointer cast, which isn't needed anyway, and doesn't work
4056 after the EMACS_INT -> ptrdiff_t change.
4057 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4058 * buffer.h: Adjust decls to match defn changes elsewhere.
4059 (struct buffer_text, struct buffer):
4060 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4061 Use EMACS_INT, not int, where int might not be wide enough.
4062 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4063 not int, to avoid needless 32-bit limit on 64-bit hosts.
4064 (exec_byte_code): Use tighter memory-full test, one that checks
4065 for alloca overflow. Don't compute the address of the object just
4066 before an array, as that's not portable. Use EMACS_INT, not
4067 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4068 * callint.c (Fcall_interactively):
4069 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4070 * callproc.c (call_process_kill, Fcall_process):
4071 Don't assume pid_t fits into an Emacs fixnum.
4072 (call_process_cleanup, Fcall_process, child_setup):
4073 Don't assume pid_t fits into int.
4074 (call_process_cleanup, Fcall_process, delete_temp_file)
4075 (Fcall_process_region):
4076 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4077 (Fcall_process): Simplify handling of volatile integers.
4078 Use int, not EMACS_INT, where int will do.
4079 * casefiddle.c (casify_object, casify_region, operate_on_word)
4080 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4081 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4082 (casify_object): Avoid integer overflow when overallocating buffer.
4083 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4084 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4085 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4086 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4087 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4088 integers are now checked earlier. All uses replaced with XINT.
4090 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4091 For CCL_MapSingle, check that content and value are in int range.
4092 (ccl_driver, Fregister_code_conversion_map):
4093 Check that Vcode_version_map_vector is a vector.
4094 (resolve_symbol_ccl_program): Check that vector header is in range.
4095 Always copy the vector, so that we can check its contents reliably
4096 now rather than having to recheck each instruction as it's being
4097 executed. Check that vector words fit in 'int'.
4098 (ccl_get_compiled_code, Fregister_ccl_program)
4099 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4100 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4101 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4102 contents are in range.
4103 (Fccl_execute_on_string): Check that status is in range.
4104 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4105 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4106 Accept and return EMACS_INT, not int, because callers can pass values
4108 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4109 (multibyte_chars_in_text, parse_str_as_multibyte)
4110 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
4111 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4112 (string_escape_byte8, Fget_byte):
4113 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4114 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4115 avoid mishandling large integers.
4116 * character.h: Adjust decls to match defn changes elsewhere.
4117 * charset.c (load_charset_map_from_file, find_charsets_in_text)
4118 (Ffind_charset_region):
4119 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4120 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
4121 (load_charset_map_from_vector, Fdefine_charset_internal):
4122 Don't assume fixnum fits in int.
4123 (load_charset_map_from_vector, Fmap_charset_chars):
4124 Remove now-unnecessary CHECK_NATNUMs.
4125 (Fdefine_charset_internal): Check ranges here, more carefully.
4126 Don't rely on undefined behavior with signed left shift overflow.
4127 Don't assume unsigned int fits into fixnum, or that fixnum fits
4128 into unsigned int. Don't require max_code to be a valid fixnum;
4129 that's not true for gb10830 4-byte on a 32-bit host. Allow
4130 invalid_code to be a cons, for the same reason. Require code_offset
4131 to be a character. Avoid int overflow if max_char is close
4133 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4134 this is intended anyway and avoids some undefined behavior.
4135 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4136 INDEX_TO_CODE_POINT, as that's what it expects.
4137 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4138 * charset.h (DECODE_CHAR): Return int, not unsigned;
4139 this is what was intended anyway, and it avoids undefined behavior.
4140 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4141 integer-overflow issues.
4142 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4143 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4144 where the argument is EMACS_INT, and this behavior is not intended.
4145 * chartab.c (Fmake_char_table, Fset_char_table_range)
4146 (uniprop_get_decoder, uniprop_get_encoder):
4147 Don't assume fixnum fits in int.
4148 * cmds.c (move_point): New function, that does the gist of

4860 BITS_PER_EMACS_INT, in #if.
4861 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4862 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4863 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4864 * s/ms-w32.h (DATA_START):
4865 Move here from removed file m/intel386.h.
4866 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4867 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4869 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4871 Assume C89 or later.
4872 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
4873 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
4875 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
4876 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
4877 * textprop.c, tparam.c (NULL): Remove.
4878 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
4879 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4880 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4881 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4882 * xterm.c (input_signal_count): Assume volatile works.
4884 2012-05-21 Ken Brown <kbrown@cornell.edu>
4886 * xgselect.c (xg_select): Fix first argument in call to 'select'
4889 2012-05-20 Ken Brown <kbrown@cornell.edu>
4891 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4892 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4894 2012-05-19 Ken Brown <kbrown@cornell.edu>
4896 * xfns.c (x_in_use): Remove `static' qualifier.
4897 * xterm.h (x_in_use): Declare.
4898 * xgselect.c: Include xterm.h.
4899 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4900 and `display_arg' (bug#9754).
4902 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4904 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4906 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4907 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4909 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4911 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4913 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4914 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4916 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4917 reference to image_cache->refcount.
4918 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4920 2012-05-17 Juri Linkov <juri@jurta.org>
4922 * search.c (Fword_search_regexp, Fword_search_backward)
4923 (Fword_search_forward, Fword_search_backward_lax)
4924 (Fword_search_forward_lax): Move functions to isearch.el
4925 (bug#10145, bug#11381).
4927 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4929 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4931 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4933 * lread.c (init_obarray): Declare Qt and Qnil as special.
4935 2012-05-14 Glenn Morris <rgm@gnu.org>
4937 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4938 Put "libexec" before "bin", for the sake of init_callproc_1.
4940 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4942 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4944 * unexaix.c: Port to more-recent AIX compilers.
4945 (report_error, report_error_1, make_hdr, copy_sym)
4946 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4947 Make arguments const char *, not char *, to avoid violations of C
4948 standard and to fix some AIX warnings reported by Gilles Pion.
4950 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4952 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4953 already have overlays loaded.
4954 (handle_single_display_spec): Before returning without displaying
4955 fringe bitmap, synchronize the bidi iterator with the main display
4956 iterator, by calling iterate_out_of_display_property.
4957 (iterate_out_of_display_property): Detect buffer iteration by
4958 testing that it->string is a Lisp string.
4959 (get_next_display_element): When the current object is exhausted,
4960 and there's something on it->stack, call set_iterator_to_next to
4961 proceed with what's on the stack, instead of returning zero.
4962 (set_iterator_to_next): If called at the end of a Lisp string,
4963 proceed to consider_string_end without incrementing string
4964 position. Don't increment display vector index past the end of
4965 the display vector. (Bug#11417)
4966 (pos_visible_p): Don't report a position visible when move_it_to
4967 stopped at the last line of window, which happens to be scanned
4968 backwards by the bidi iteration. (Bug#11464)
4970 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4972 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4973 and right-margin display specs even if the spec is invalid or we
4974 are on a TTY, and thus unable to display on the fringes.
4975 That's because the text with the property will not be displayed anyway,
4976 so we need to signal to the caller that this is a "replacing"
4977 display spec. This fixes display when the spec is invalid or we
4980 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4982 * unexaix.c (make_hdr): Fix typo in prototype.
4983 This bug broke the build on AIX. Problem reported by Gilles Pion.
4985 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4987 * keyboard.c (kbd_buffer_get_event): Read special events also in
4988 batch mode. (Bug#11415)
4990 2012-05-12 Glenn Morris <rgm@gnu.org>
4992 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4994 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4996 * lisp.mk (lisp): Add newcomment.elc.
4998 2012-05-12 Glenn Morris <rgm@gnu.org>
5000 * Makefile.in (MKDIR_P): New, set by configure.
5001 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5003 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5005 Remove unused function hourglass_started.
5006 * dispextern.h (hourglass_started):
5007 * w32fns.c (hourglass_started):
5008 * xdisp.c (hourglass_started): Remove.
5010 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5012 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5013 Update dependencies.
5015 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5017 * xgselect.c (xg_select): Put maxfds+1 into a var.
5018 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5020 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5022 2012-05-10 Dave Abrahams <dave@boostpro.com>
5024 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5025 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5027 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5029 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5030 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5031 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5032 Initialize xd_registered_buses.
5034 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5036 Untag more efficiently if USE_LSB_TAG.
5037 This is based on a proposal by YAMAMOTO Mitsuharu in
5038 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5039 For an admittedly artificial (nth 8000 longlist) benchmark on
5040 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5041 Emacs's overall text size by 1%.
5042 * lisp.h (XUNTAG): New macro.
5043 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5044 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5045 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5046 * eval.c (Fautoload):
5047 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5048 * frame.h (XFRAME): Use XUNTAG.
5050 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5051 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5052 Remove unportable assumptions about print widths of types like
5054 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5055 intptr_t when converting between pointer and integer, to avoid GCC
5056 warnings about wrong width.
5058 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5060 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5061 stack for each reader_thread, instead of defaulting to 8MB
5062 determined by the linker. This avoids failures in creating
5063 subprocesses on Windows 7, see the discussion in this thread:
5064 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5066 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5068 Fix up display of the *Minibuf-0* buffer in the mini window.
5069 * keyboard.c (read_char): Don't clear the echo area if there's no
5071 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5072 contents of *Minibuf-0*) if there's no message displayed in its stead.
5074 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5076 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5079 2012-05-06 Chong Yidong <cyd@gnu.org>
5081 * lisp.mk (lisp): Update.
5083 2012-05-05 Jim Meyering <meyering@redhat.com>
5085 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5087 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5089 * data.c (PUT_ERROR): New macro.
5090 (syms_of_data): Use it. Add new error type `user-error'.
5091 * undo.c (user_error): New function.
5092 (Fprimitive_undo): Use it.
5093 * print.c (print_error_message): Adjust print style for `user-error'.
5094 * keyboard.c (user_error): New function.
5095 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5097 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5099 Do not limit current-time-string to years 1000..9999.
5100 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5101 (Fcurrent_time_string): Support any year that is supported by the
5102 underlying localtime representation. Don't use asctime, as it
5103 has undefined behavior for years outside the range -999..9999.
5105 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5107 Fix race conditions involving setenv, gmtime, localtime, asctime.
5108 Without this fix, interrupts could mess up code that uses these
5109 nonreentrant functions, since setting TZ invalidates existing
5110 tm_zone or tzname values, and since most of these functions return
5111 pointers to static storage.
5112 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5113 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5114 Grow the critical sections to include not just invoking
5115 localtime/gmtime, but also accessing these functions' results
5116 including their tm_zone values if any, and any related TZ setting.
5117 (format_time_string): Last arg is now struct tm *, not struct tm **,
5118 so that the struct tm is saved in the critical section.
5119 All callers changed. Simplify allocation of initial buffer, partly
5120 motivated by the fact that memory allocation needs to be outside
5121 the critical section.
5123 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5125 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5126 with RESET_INTERVAL.
5128 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5129 Remove duplicated buffer name initialization.
5131 2012-05-02 Jim Meyering <jim@meyering.net>
5133 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5135 * xfns.c (x_window): Use xstrdup (Bug#11375).
5137 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5139 * xdisp.c (pos_visible_p): If already at a newline from the
5140 display string before the 'while' loop, don't walk back the glyphs
5141 from it3.glyph_row. Solves assertion violation when the display
5142 string begins with a newline (egg.el). (Bug#11367)
5144 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5146 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5149 2012-05-01 Glenn Morris <rgm@gnu.org>
5151 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5152 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5153 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5154 All were removed before 23.1.
5156 * dispnew.c: Remove HAVE_LIBNCURSES test;
5157 it is always true on relevant platforms.
5159 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5160 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5162 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5164 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5166 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5167 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5170 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5172 Do not avoid creating empty evaporating overlays (Bug#9642).
5173 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5174 That is, do not delete an evaporating overlay if it becomes
5175 empty after its bounds are adjusted to fit within its buffer.
5176 This fix caused other problems, and I'm reverting it until we get
5177 to the bottom of them.
5179 2012-04-27 Chong Yidong <cyd@gnu.org>
5181 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5183 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5185 * xdisp.c (pos_visible_p): If the window start position is beyond
5186 ZV, start the display from buffer beginning. Prevents assertion
5187 violation in init_iterator when the minibuffer window is scrolled
5190 * window.c (window_scroll_pixel_based): Likewise.
5192 2012-04-27 Chong Yidong <cyd@gnu.org>
5194 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5196 2012-04-27 Glenn Morris <rgm@gnu.org>
5198 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5199 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5201 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5203 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5204 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5206 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5208 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5209 display element, check also the underlying string or buffer
5210 character. (Bug#11341)
5212 * w32menu.c: Include w32heap.h.
5213 (add_menu_item): If the call to AppendMenuW (via
5214 unicode_append_menu) fails, disable Unicode menus only if we are
5215 running on Windows 9X/Me.
5217 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5219 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5220 (xgetint): Add missing shift for LSB tags.
5222 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5224 * keyboard.c (read_char): Don't wipe echo area for select window
5225 events: These might get delayed via `mouse-autoselect-window'
5228 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5230 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5231 manipulation of :loaded-from data.
5233 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5235 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5236 now a cons (bug#11311).
5238 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5240 Do not create empty overlays with the evaporate property (Bug#9642).
5241 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5242 if it becomes empty after its bounds are adjusted to fit within
5243 its buffer. Without this fix, in a nonempty buffer (let ((o
5244 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5245 yields an empty overlay that has the evaporate property, which is
5246 not supposed to happen.
5248 Fix minor GTK3 problems found by static checking.
5249 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5250 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5251 (struct _EmacsFixedClass, emacs_fixed_get_type):
5252 Move decls here from emacsgtkfixed.h, since they needn't be public.
5253 (emacs_fixed_get_type): Now static.
5254 (emacs_fixed_class_init): Omit unused local.
5255 (emacs_fixed_child_type): Remove; unused.

5257 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5258 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
5259 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5260 (EMACS_FIXED_GET_CLASS): Remove; unused.
5261 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5263 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5264 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5266 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5268 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5269 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5270 (__malloc_size_t, __malloc_ptrdiff_t):
5271 Remove. All uses removed, replaced by the definiens if needed,
5272 since we can assume C89 or better now.
5273 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5274 (protect_malloc_state, align, get_contiguous_space)
5275 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5281 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5282 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5283 Define using prototypes, not old style.
5284 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5285 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5286 (align): Don't assume that signed integer overflow wraps around.
5287 Omit unused local var.
5288 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5289 (_free_internal_nolock, memalign, mallochook, reallochook):
5290 Omit no-longer-needed casts.
5291 (valloc): Use getpagesize, not __getpagesize.
5292 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
5293 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5295 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5297 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
5299 Move functions from C to Lisp. Make non-blocking method calls
5300 the default. Implement further D-Bus standard interfaces.
5302 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
5303 (QCdbus_request_name_allow_replacement)
5304 (QCdbus_request_name_replace_existing)
5305 (QCdbus_request_name_do_not_queue)

5310 (QCdbus_registered_serial, QCdbus_registered_method)
5311 (QCdbus_registered_signal): New Lisp objects.

5348 * alloc.c: Handle unusual debugging option combinations.
5349 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5350 since the two debugging options are incompatible.
5351 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5353 (mem_init, mem_insert, mem_insert_fixup):
5354 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5384 * print.c (print_preprocess): Only check print_depth if print-circle
5386 (print_object): Check for cycles even when print-circle is nil and
5387 print-gensym is t, but only check print_depth if print-circle is nil.
5389 2012-04-20 Chong Yidong <cyd@gnu.org>
5391 * process.c (wait_reading_process_output): If EIO occurs on a pty,

5447 New extern decls, to avoid calling undeclared functions.
5448 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5449 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5450 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

5491 Remove definition of GC_MARK_STACK, since the default now works.
5492 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5493 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5494 no longer the default.
5495 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5497 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5499 * lread.c (lisp_file_lexically_bound_p):

5520 2012-04-11 Daniel Colascione <dancol@dancol.org>
5522 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5523 against is gone. It's better to use vfork now so that when Cygwin
5524 gains a new, working vfork, we use it automatically (bug#10398).
5526 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5547 being loaded (bug#10424).
5549 2012-04-09 Glenn Morris <rgm@gnu.org>
5551 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5552 not just in the obarray, before snarfing them. (Bug#11036)

5579 * minibuf.c (Fread_variable): Callers changed.
5581 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5583 * xdisp.c (set_cursor_from_row): If the display string appears in
5584 the buffer at position that is closer to point than the position
5585 after the display string, display the cursor on the first glyph of
5586 the display string. Fixes cursor display when a 'display' text
5587 property immediately follows invisible text. (Bug#11094)
5589 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5591 composite.c: use 'double' consistently
5592 * composite.c (get_composition_id): Use 'double' consistently
5593 instead of converting 'float' to 'double' and vice versa; this is
5594 easier to understand and avoids a GCC warning.
5596 2012-04-09 Glenn Morris <rgm@gnu.org>
5598 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5599 preparation for dumping it with emacs. (Bug#4789)

5642 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5643 [!WINDOWSNT]: New macros.
5644 (init_libxml2_functions, libxml2_loaded_p): New functions.
5645 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5646 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5647 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5648 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5650 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5651 Call init_libxml2_functions before calling libxml2 functions.
5652 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5654 * emacs.c: Don't include libxml/parser.h.

5668 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5669 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5670 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5671 macros related to unification of CJK characters. For the details,
5672 see the discussion following the message here:
5673 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5675 2012-04-04 Chong Yidong <cyd@gnu.org>
5677 * keyboard.c (Vdelayed_warnings_list): Doc fix.

5689 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5691 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5692 position we get to after a call to move_it_to fails the
5693 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5694 only if we wind up in a string from display property. (Bug#11063)
5696 * window.c (Fdelete_other_windows_internal): Invalidate the row
5697 and column information about mouse highlight, so that redisplay
5698 restores it after reallocating the glyph matrices. (Bug#7464)
5700 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5701 string comes from a `display' text property, use the buffer
5702 position of that property as if we actually saw that position in
5704 (move_it_by_lines): Remove the assertion that
5705 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5706 violated when there's a before-string at the beginning of a line.
5709 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5711 * xdisp.c (append_space_for_newline): If the default face was
5712 remapped, use the remapped face for the appended newline.
5713 (extend_face_to_end_of_line): Use the remapped default face for
5714 extending the face to the end of the line.
5715 (display_line): Call extend_face_to_end_of_line when the default
5716 face was remapped. (Bug#11068)
5718 2012-03-29 Eli Zaretskii <eliz@gnu.org>

5749 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5751 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5753 * s/ms-w32.h (tzname): Include time.h before redirecting to

5764 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5766 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5767 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5768 when fetching a multibyte character consumes more bytes than
5769 CHAR_BYTES returns, due to unification of CJK characters in
5770 string_char. (Bug#11073)
5772 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5774 * process.c (wait_reading_process_output): Handle pty disconnect
5775 by refraining from sending oneself a SIGCHLD (bug#10933).

5798 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5799 to reflect default non-nil value of redisplay-dont-pause.
5801 2012-03-19 Kenichi Handa <handa@m17n.org>
5803 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5804 it fit in a valid range (Bug#11003).
5806 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5808 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5809 that is not from display property, accept the row as a "cursor
5810 row" if one of the string's character has a non-nil `cursor'
5811 property. Fixes cursor positioning when there are newlines in
5812 overlay strings, e.g. in icomplete.el. (Bug#11035)
5814 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

5845 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5848 2012-03-03 Glenn Morris <rgm@gnu.org>
5850 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

5863 * buffer.c (buffer-list-update-hook): Doc fix.
5865 2012-02-29 Eli Zaretskii <eliz@gnu.org>

5868 push_it before setting up the iterator for the first overlay
5869 string, even if we have an empty string loaded.
5870 (next_overlay_string): If there's an empty string on the iterator
5871 stack, pop the stack. (Bug#10903)
5873 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5875 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5876 Suggested by Stefan Monnier in
5877 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5878 * alloc.c (widen_to_Lisp_Object): New static function.
5879 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5880 and widening them to Lisp_Objects. This would work even if
5881 USE_LSB_TAG is defined and wide integers are used, which might
5882 happen in a future version of Emacs.
5884 2012-02-25 Chong Yidong <cyd@gnu.org>
5886 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

5891 before saving to clipboard manager.
5893 2012-02-24 Chong Yidong <cyd@gnu.org>
5895 * keyboard.c (process_special_events): Handle all X selection
5896 requests in kbd_buffer, not just the next one (Bug#8869).
5898 2012-02-23 Chong Yidong <cyd@gnu.org>
5900 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5901 call when setting menu-bar-lines and tool-bar-lines parameters.
5902 (unwind_create_frame_1): New helper function.
5904 * window.c (inhibit_window_configuration_change_hook): New var.
5905 (run_window_configuration_change_hook): Obey it.
5906 (syms_of_window): Initialize it.
5908 2012-02-22 Chong Yidong <cyd@gnu.org>
5910 * xterm.c (x_draw_image_relief): Add missing type check for

5923 when computing $valmask.
5925 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5926 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5927 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5928 It's useless in that case, and it can cause problems on hosts
5929 that allocate halves of EMACS_INT values separately.
5930 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5931 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5932 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5933 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5934 it avoids undefined behavior on hosts where shifting right by more
5935 than the word width has undefined behavior.
5937 2012-02-19 Chong Yidong <cyd@gnu.org>
5939 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5940 (Funhandled_file_name_directory, Ffile_name_as_directory)

5959 2012-02-15 Chong Yidong <cyd@gnu.org>
5961 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5962 marked as special. Also, starting docstrings with * is obsolete.
5964 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

5977 2012-02-12 Chong Yidong <cyd@gnu.org>
5979 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5980 as that creates a dangerous corner case.
5982 * window.c (Fdelete_window_internal): Invalidate the mouse
5983 highlight (Bug#9904).
5985 2012-02-12 Glenn Morris <rgm@gnu.org>

5990 * nsselect.m (Fx_own_selection_internal)
5991 (Fx_disown_selection_internal, Fx_selection_exists_p)
5992 (Fx_selection_owner_p, Fx_get_selection_internal):
5993 Sync docs and argument specs with the xselect.c versions.

6015 2012-02-07 Chong Yidong <cyd@gnu.org>
6017 * buffer.c (Fbuffer_local_variables)
6018 (buffer_lisp_local_variables): Handle unbound vars correctly;
6019 don't let Qunbound leak into Lisp.
6021 2012-02-07 Glenn Morris <rgm@gnu.org>
6023 * image.c (Fimagemagick_types): Doc fix.
6025 * image.c (imagemagick-render-type): Change it from a lisp object

6031 * doc.c (store_function_docstring): Avoid applying docstring of
6032 alias to base function (Bug#2603).

6058 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
6060 Handle overflow when computing char display width (Bug#9496).
6061 * character.c (char_width): Return EMACS_INT, not int.
6062 (char_width, c_string_width): Check for overflow when
6063 computing the width; this is possible now that individual
6064 characters can have unbounded width. Problem introduced
6065 by merge from Emacs 23 on 2012-01-19.
6067 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

6096 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
6097 first 2 arguments are identical. This makes inserting large
6098 output from a subprocess an order of magnitude faster on
6099 MS-Windows, where all sbrk'ed memory is always contiguous.

6203 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
6205 emacs: fix an auto-save permissions race condition (Bug#10400)
6206 * fileio.c (auto_saving_dir_umask): New static var.
6207 (Fmake_directory_internal): Use it.
6208 (do_auto_save_make_dir): Set it, instead of invoking chmod after
6209 creating the directory. The old code temporarily assigns
6210 too-generous permissions to the directory.
6211 (do_auto_save_eh): Clear it.
6212 (Fdo_auto_save): Catch all errors, not just file errors, so
6213 that the var is always cleared.

6270 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
6271 property that ends at ZV, so that the bidi iteration could be

6719 is set, removing the need for VIRT_ADDRESS_VARIES.
6720 (PURE_P): Use a more-efficient implementation that needs just one

6735 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6736 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6737 behave as if the cursor position were at the window margin.
6739 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6740 and the cursor position is out of bounds, behave as if the cursor
6741 position were at the window margin. (Bug#10075)
6743 2011-11-18 Chong Yidong <cyd@gnu.org>
6745 * window.c (Fwindow_combination_limit): Make first argument

6768 (compute_line_metrics): Call row_hash, instead of computing the
6771 * dispnew.c (verify_row_hash): Call row_hash for computing the
6772 hash code of a row, instead of duplicating code from xdisp.c.

6967 (static_offset_intervals): Remove.
6968 (offset_intervals): Rewrite using the old contents of
6969 static_offset_intervals. The old version didn't conform to C99

6993 (Fwindow_vscroll): Doc fix.

7246 * w32reg.c (x_get_string_resource): Silence compiler warnings.
7248 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
7250 * w32fns.c (w32_default_color_map): New function,
7251 extracted from Fw32_default_color_map.
7252 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
7254 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
7256 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
7258 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
7260 * keyboard.c (test_undefined): New function (bug#9751).
7261 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7263 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7265 * sysdep.c (init_sys_modes): Fix the check for the controlling
7266 terminal (Bug#6649).
7268 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7270 * dispextern.h (struct bidi_it): New member next_en_type.
7272 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7273 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7274 current character, check also for next_en_type being WEAK_EN.
7275 (bidi_resolve_weak): Don't enter the expensive loop if the current
7276 position is before next_en_pos. Record the bidi type of the first
7277 non-ET, non-BN character we find, in addition to its position.
7278 (bidi_level_of_next_char): Invalidate next_en_type when
7279 next_en_pos is over-stepped.
7281 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7283 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7284 * editfns.c: Rewrite current-time-zone so that it invokes
7285 the equivalent of (format-time-string "%Z") to get the time zone name.
7286 This fixes a bug when the time zone name contains characters that
7287 need converting from the system time locale to Emacs internal format.
7288 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7289 that patch fixed format-time-string to do the conversion, but
7290 I forgot to fix current-time-zone.
7291 (format_time_string): New function, containing most of
7292 what Fformat_time_string used to contain.
7293 (Fformat_time_string): Rewrite in terms of format_time_string.
7294 This doesn't change this function's behavior.
7295 (current-time-zone): Rewrite to use format_time_string.
7296 This fixes the bug reported by Michael Schierl in
7297 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7298 Jason Rumney's 2007-06-07 change worked around this bug, but
7300 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7302 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7304 * xdisp.c (start_display): If the character at POS is displayed
7305 via a display vector, reset IT->current.dpvec_index to zero.
7306 (try_window_reusing_current_matrix): If a line ends in a display
7307 vector or the next line starts in a display vector, continue
7308 redrawing the window even though the character position of
7309 start_row was reached.
7312 2011-10-18 Chong Yidong <cyd@gnu.org>
7314 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7315 with nobreak-char-display too.
7317 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7319 Fix part 3 of bug#9771.
7320 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7321 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7322 non-neutral characters if the current character is a paragraph
7323 separator (a.k.a. Newline). This avoids running the same
7324 expensive loop twice, once when we consume the preceding newline
7325 and the other time when the line actually needs to be displayed.
7326 Avoid the loop when we see neutrals on the base embedding level
7327 following a character whose directionality is the same as the
7328 paragraph's. This avoids running the expensive loop when a line
7329 ends in a long sequence of neutrals, like control characters.
7330 Add assertion against STRONG_AL type. Slightly rearrange code
7331 that determines the type of a neutral given the first non-neutral
7333 (bidi_level_of_next_char): Set next_en_pos to zero when
7334 invalidating its info.
7336 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7338 * xdisp.c (push_display_prop): Determine whether to record string
7339 or buffer position by IT->string, not by IT->method. Allow
7340 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7341 (move_it_vertically_backward): Don't look for character position
7342 immediately after the newline when in a continuation line.
7345 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7347 * window.c (coordinates_in_window): Rewrite and delabelize
7348 vertical border check. (Bug#5357) (Bug#9618)
7350 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7352 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7353 errors in XSetWindowBorder (bug#9310).
7355 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7357 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7358 avoid crash when xmalloc overrun checking is enabled.
7360 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7362 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7363 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7364 cursor motion with <left> and <right> arrow keys.
7366 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7367 some callers set that themselves.
7369 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7371 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7372 display string and the previous row comes from the same string and
7373 is empty. (Bug#9739) (Bug#9738)
7375 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7377 * doc.c (get_doc_string): Encode file name (bug#9735).
7379 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7381 * bidi.c (bidi_level_of_next_char):
7382 * xdisp.c (get_visually_first_element): Remove old incorrect
7383 comments regarding the Unicode Line Separator character.
7385 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7387 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7389 * alloc.c (Fgc_status): Do not access beyond zombies array
7390 boundary if nzombies > MAX_ZOMBIES.
7391 * alloc.c (dump_zombies): Add missing format specifier.
7393 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7395 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7396 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7398 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7399 Some packages use them to denote characters with modifiers.
7401 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7403 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7404 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7405 matching a pp-number. Rename parameter var to var1.
7407 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7409 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7411 2011-10-08 Glenn Morris <rgm@gnu.org>
7413 * callint.c (Fcall_interactively): Give a more explicit error for the
7414 'c' case with a non-character input. (Bug#8479)
7416 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7418 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7420 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7421 lines that are hscrolled on the left.
7423 * dispnew.c (buffer_posn_from_coords): Account for a possible
7424 presence of header-line. (Bug#4426)
7426 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7428 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7429 Don't advertise functionality which we discourage or doesn't work.
7431 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7433 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7434 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7435 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7436 this makes Emacs dump core during garbage collection on rare
7437 occasions. sizeof is obviously inferior to offsetof here, so
7438 stick with offsetof.
7439 (GC_POINTER_ALIGNMENT): New macro.
7440 (mark_memory): Omit 3rd (offset) arg; caller changed.
7441 Don't assume EMACS_INT alignment is the same as pointer alignment.
7443 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7445 * keyboard.c (read_key_sequence_remapped): New var.
7446 (read_key_sequence): Compute remapping in the right buffer.
7447 (command_loop_1): Use read_key_sequence's remapping directly.
7449 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7451 * dired.c (file_name_completion): Don't expand file name.
7452 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7453 before checking file name handler.
7455 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7456 they've been requested explicitly (bug#9591).
7458 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7460 * keymap.c (Fsingle_key_description): Use make_specified_string
7461 instead of build_string to build string from push_key_description.
7464 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7466 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7467 This fixes a Y2038 bug on 64-bit hosts.
7468 * buffer.c (reset_buffer):
7469 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7470 (Fclear_buffer_auto_save_failure):
7471 Use 0, not -1, to represent an unset failure time, since time_t
7472 might not be signed.
7474 Remove dependency on glibc malloc internals.
7475 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7476 Move back here from lisp.h, but with their new implementations.
7477 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7478 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7479 * charset.c (charset_table_init): New static var.
7480 (syms_of_charset): Use it instead of xmalloc. This removes a
7481 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7482 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7483 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7484 Move back to alloc.c.
7485 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7486 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7488 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7490 * nsterm.m (windowDidResize): Call x_set_window_size only when
7491 ns_in_resize is true. Otherwise set pixelwidth/height and
7492 call change_frame_size (Bug#9628).
7494 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7496 Port --enable-checking=all to Fedora 14 x86-64.
7497 * charset.c (syms_of_charset): Also account for glibc malloc's
7498 internal overhead when calculating the initial malloc maximum.
7500 Port --enable-checking=all to Fedora 14 x86.
7501 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7503 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7504 (overrun_check_realloc, overrun_check_free):
7505 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7506 That way, xmalloc returns a properly-aligned pointer even if
7507 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7508 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7509 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7510 into account when calculating the initial malloc maximum.
7511 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7512 Move here from alloc.c, so that charset.c can use it too.
7513 Properly align; the old code wasn't right for common 32-bit hosts
7514 when configured with --enable-checking=all.
7515 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7516 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7518 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7520 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7523 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7525 * xdisp.c (compute_display_string_end): If there's no display
7526 string at CHARPOS, return -1.
7528 * bidi.c (bidi_fetch_char): When compute_display_string_end
7529 returns a negative value, treat the character as a normal
7530 character not covered by a display string. (Bug#9624)
7532 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7534 * lread.c (Fread_from_string): Fix typo in docstring.
7536 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7538 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7539 newline, reseat the iterator instead of bidi-iterating there one
7540 character at a time. (Bug#9610)
7541 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7542 TO_CHARPOS if the bidi iterator is at base embedding level.
7544 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7546 * lread.c (readevalloop): Use correct code for NBSP.
7547 (read1): Likewise. (Bug#9608)
7549 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7551 * dbusbind.c (Fdbus_register_signal): When service is not
7552 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7554 2011-09-25 Glenn Morris <rgm@gnu.org>
7556 * buffer.c (truncate-lines): Doc fix.
7558 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7560 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7561 (Fset_window_next_buffers): Doc fix.
7563 2011-09-24 Glenn Morris <rgm@gnu.org>
7565 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7567 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7569 Fix minor problems found by static checking.
7570 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7571 * indent.c (Fvertical_motion): Fix == vs = typo.
7573 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7575 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7576 Default value is now t. Doc fix.
7578 * indent.c (Fvertical_motion): Compute and apply the overshoot
7579 logic when moving up, not only when moving down. Fix the
7580 confusing name and values of the it_overshoot_expected variable;
7581 logic changes accordingly. (Bug#9254) (Bug#9549)
7583 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7584 CHARPOS is covered by a display string which includes newlines.
7585 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7586 is covered by a display string with embedded newlines.
7588 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7590 * dbusbind.c (Fdbus_register_signal): Add match rule to
7591 Vdbus_registered_objects_table. (Bug#9581)
7592 (Fdbus_register_method, Vdbus_registered_objects_table):
7595 2011-09-24 Jim Meyering <meyering@redhat.com>
7597 do not ignore write error for any output size
7598 The previous change was incomplete.
7599 While it makes emacs --batch detect the vast majority of stdout
7600 write failures, errors were still ignored whenever the output size is
7601 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7602 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7603 && echo FAIL: ignored write error
7604 FAIL: ignored write error
7605 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7606 && echo FAIL: ignored write error
7607 FAIL: ignored write error
7608 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7610 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7612 * emacs.c (Fkill_emacs): In noninteractive mode exit
7613 non-successfully if a write error occurred on stdout. (Bug#9574)
7615 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7617 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7620 * dispextern.h (struct it): Update the comment documenting what
7623 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7625 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7626 a display string, extend search for cursor position to end of row.
7627 (find_row_edges): If the row ends in a newline from a display
7628 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7629 Handle the case of a display string with multiple newlines.
7630 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7631 non-empty line. Fixes confusing cursor motion with arrow keys at
7632 the beginning of a line that starts with whitespace.
7634 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7636 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7639 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7641 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7644 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7646 * xdisp.c (display_line): Record maximum and minimum buffer
7647 positions even if no glyphs were produced (e.g., by a zero-width
7648 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7649 buffer positions that will be removed from the glyph row because
7651 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7652 column is beyond frame width: don't subtract 1 "pixel" when
7653 computing width of the stretch.
7654 (reseat_at_next_visible_line_start): Undo the change made on
7655 2011-09-17 that saved paragraph information and restored it after
7656 the call to `reseat'. (Bug#9545)
7658 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7660 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7661 and turn window cursor on if cleared (Bug#9415).
7663 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7665 * search.c (boyer_moore): Take unibyte characters from pattern
7666 literally. (Bug#9458)
7668 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7670 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7672 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7674 Fix minor problem found by static checking.
7675 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7676 initialized, to pacify gcc -Wuninitialized.
7678 * fileio.c: Report proper errno when syscall falls.
7679 (Finsert_file_contents): Save and restore errno,
7680 so that report_file_error outputs the correct diagnostic.
7681 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7683 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7685 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7687 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7689 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7690 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7692 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7694 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7695 about the current paragraph and restore it after the call to reseat.
7697 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7698 (bidi_find_paragraph_start): Search back for paragraph beginning
7699 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7700 (bidi_move_to_visually_next): Only trigger paragraph-related
7701 computations when the last character is a newline or at EOB, not
7702 just any NEUTRAL_B. (Bug#9470)
7704 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7705 truncated lines if point is covered by a display string. (Bug#9524)
7707 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7709 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7710 (cons_to_x_long): New function.
7711 (lisp_data_to_selection_data): Use it. Correct the test for
7712 short-versus-long data; it was negated. Break out of vector
7713 loop, for efficiency, when a long datum is discovered.
7715 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7717 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7719 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7721 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7722 GCC PR/17406) by declaring this function with external scope.
7724 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7726 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7727 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7729 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7731 * editfns.c (Fformat): Correctly handle text properties on "%%".
7733 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7735 * xterm.c (x_draw_composite_glyph_string_foreground):
7736 * w32term.c (x_draw_composite_glyph_string_foreground):
7737 * term.c (encode_terminal_code):
7738 * composite.c (composition_update_it, get_composition_id):
7739 * xdisp.c (get_next_display_element)
7740 (fill_composite_glyph_string): Add comments about special meaning
7741 of TAB characters in a composition.
7743 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7745 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7746 This occurs when processing a multibyte format.
7747 Problem reported by Wolfgang Jenker.
7749 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7751 * xdisp.c (try_cursor_movement): Only check for exact match if
7752 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7754 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7756 Remove unused external symbols.
7757 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7758 * xdisp.c (calc_pixel_width_or_height): Now static.
7759 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7760 * indent.c (check_display_width):
7761 * w32term.c: Fix comment to match code.
7762 * xterm.c, xterm.h (x_catching_errors): Remove.
7764 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7766 * xselect.c: Use signed conversions more consistently (Bug#9498).
7767 (selection_data_to_lisp_data): Assume incoming selection data are
7768 signed integers, not unsigned. This is to be consistent with
7769 outgoing selection data, which was modified to use signed integers
7770 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7771 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7772 expects long, not unsigned long.
7774 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7776 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7777 computation of loop end. Reported by Johan Bockgård
7780 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7782 * frame.c (Fother_visible_frames_p): Function deleted.
7784 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7786 * indent.c (compute_motion): Process display vector front to back
7787 rather than the other way around. (Bug#2496)
7789 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7791 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7793 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7795 * minibuf.c (Fread_from_minibuffer): Doc fix.
7797 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7799 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7800 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7802 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7804 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7805 value for non-existent files.
7807 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7809 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7810 set its "size" to -1. This will set the modtime_size field of
7811 the corresponding buffer to -1, which is what
7812 verify-visited-file-modtime expects for files that do not exist.
7815 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7817 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7819 * lisp.h: ... from here. push_key_description is no longer
7820 defined in keyboard.c, so its declaration should not be in
7821 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7822 logically belongs with push_key_description.
7824 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7826 * buffer.h: Include <sys/types.h> instead of <time.h>.
7827 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7828 Problem reported by Herbert J. Skuhra.
7830 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7832 * xml.c (parse_region): Make the parsing work for
7833 non-comment-starting XML files again (bug#9144).
7835 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7837 * image.c (gif_load): Fix calculation of bottom and right corner.
7840 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7842 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7843 redisplay in small windows.
7845 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7847 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7849 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7851 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7852 Operate on live windows only.
7854 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7856 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7858 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7860 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7861 only under bidi iteration.
7863 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7865 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7867 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7869 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7870 Without this fix, the command to link temacs failed due to an
7871 undefined symbol __builtin_isnan. This is because
7872 /usr/include/iso/math_c99.h #defines isnan(x) to
7873 __builtin_isnan(x), but the bundled gcc, which identifies itself
7874 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7876 * floatfns.c (isnan): #undef, and then #define to a clone of
7878 (Fisnan): Always define, since it's always available now.
7879 (syms_of_floatfns): Always define isnan at the Lisp level.
7881 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7883 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7885 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7887 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7888 The previous code assumed that file offsets (off_t values) fit in
7889 EMACS_INT variables, which is not true on typical 32-bit hosts.
7890 The code messed up by falsely reporting buffer overflow in cases
7891 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7892 when "big" contains more than 2**29 bytes, even though this
7893 inserts just one byte and does not overflow the buffer.
7894 (Finsert_file_contents): Store file offsets as off_t
7895 values, not as EMACS_INT values. Check for overflow when
7896 converting between EMACS_INT and off_t. When checking for
7897 buffer overflow or for overlap, take the offsets into account.
7898 Don't use EMACS_INT for small values where int suffices.
7899 When checking for overlap, fix a typo: ZV was used where
7900 ZV_BYTE was intended.
7901 (Fwrite_region): Don't assume off_t fits into 'long'.
7902 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7904 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7906 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7908 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7910 sprintf-related integer and memory overflow issues (Bug#9412).
7912 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7913 (esprintf, exprintf, evxprintf): New functions.
7914 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7915 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7916 (modify_event_symbol): Do not assume that the length of
7917 name_alist_or_stem is safe to alloca and fits in int.
7918 (Fexecute_extended_command): Likewise for function name and binding.
7919 (Frecursion_depth): Wrap around reliably on integer overflow.
7920 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7921 since some callers pass EMACS_INT values.
7922 (Fsingle_key_description): Don't crash if symbol name contains more
7923 than MAX_ALLOCA bytes.
7924 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7925 (get_minibuffer): Arg is now EMACS_INT, not int.
7926 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7927 (esprintf, exprintf, evxprintf): New decls.
7928 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7930 * dbusbind.c (signature_cat): New function.
7931 (xd_signature, Fdbus_register_signal):
7932 Do not overrun buffer; instead, report string overflow.
7934 * dispnew.c (add_window_display_history): Don't overrun buffer.
7935 Truncate instead; this is OK since it's just a log.
7937 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7938 even if the time zone offset is outlandishly large.
7939 Don't mishandle offset == INT_MIN.
7941 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7942 when creating daemon; the previous buffer-overflow check was incorrect.
7944 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7945 which has the guts of the old verror function.
7947 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7948 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7950 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7951 (font_unparse_xlfd): Don't blindly alloca long strings.
7952 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7953 fits in int, when using sprintf. Use single snprintf to count
7954 length of string rather than counting it via multiple sprintfs;
7955 that's simpler and more reliable.
7956 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7957 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7958 sprintf, in case result does not fit in int.
7960 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7961 (fontset_from_font): Print it.
7963 * frame.c (tty_frame_count): Now printmax_t, not int.
7964 (make_terminal_frame, set_term_frame_name): Print it.
7965 (x_report_frame_params): In X, window IDs are unsigned long,
7966 not signed long, so print them as unsigned.
7967 (validate_x_resource_name): Check for implausibly long names,
7968 and don't assume name length fits in 'int'.
7969 (x_get_resource_string): Don't blindly alloca invocation name;
7970 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7973 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7974 (xg_check_special_colors, xg_set_geometry):
7975 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7977 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7978 Use esprintf, not sprintf, in case result does not fit in int.
7980 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7981 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7982 it as a large positive number.
7983 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7984 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7986 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7987 in case result does not fit in int.
7989 * print.c (float_to_string): Detect width overflow more reliably.
7990 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7991 buffer overrun. Don't assume list length fits in 'int'. Treat
7992 print length of 0 as 0, not as infinity; to be consistent with other
7993 uses of print length in this function. Don't overflow print length
7994 index. Don't assume hash table size fits in 'long', or that
7995 vectorlike size fits in 'unsigned long'.
7997 * process.c (make_process): Use printmax_t, not int, to format
7998 process-name gensyms.
8000 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8002 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8003 to avoid potential buffer overrun.
8005 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8006 if X resource line is longer than 512 bytes.
8008 * xfns.c (x_window): Make sprintf buffer a bit bigger
8009 to avoid potential buffer overrun.
8011 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8013 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8015 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8017 Integer overflow fixes for scrolling, etc.
8018 Without these, Emacs silently mishandles large integers sometimes.
8019 For example, "C-u 4294967297 M-x recenter" was treated as if
8020 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8022 * xdisp.c (try_window_id): Check Emacs fixnum range before
8023 converting to 'int'.
8025 * window.c (window_scroll_line_based, Frecenter):
8026 Check that an Emacs fixnum is in range before assigning it to 'int'.
8027 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8028 values converted from Emacs fixnums.
8029 (Frecenter): Don't wrap around a line count if it is out of 'int'
8030 range; instead, treat it as an extreme value.
8031 (Fset_window_configuration, compare_window_configurations):
8032 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8034 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8035 that can exceed INT_MAX. Check that EMACS_INT value is in range
8036 before assigning it to the (possibly-narrower) index.
8037 (match_limit): Don't assume that a fixnum can fit in 'int'.
8039 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8042 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8043 (Fvertical_motion): Don't wrap around LINES values that don't fit
8044 in 'int'. Instead, treat them as extreme values. This is good
8045 enough for windows, which can't have more than INT_MAX lines anyway.
8047 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8049 * Require libxml/parser.h to avoid compilation warning.
8051 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8053 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8054 since this reportedly can destroy thread storage.
8056 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8058 * syntax.c (find_defun_start): Update all cache variables if
8059 exiting early (Bug#9401).
8061 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8063 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8065 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8066 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8067 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8069 * term.c (tty_append_glyph): New function.
8070 (produce_stretch_glyph): Static function and its prototype deleted.
8072 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8075 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8077 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8078 when checking :margin (Bug#9390).
8079 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8080 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8081 so that the name doesn't mislead. All uses changed.
8083 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8085 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8088 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8090 * xdisp.c (move_it_to): Don't bail out early when reaching
8091 position beyond to_charpos, if we are scanning backwards.
8092 (move_it_vertically_backward): When DY == 0, make sure we get to
8093 the first character in the line after the newline.
8095 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8097 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8098 (ccl_driver): Do not generate an out-of-range pointer.
8099 (Fccl_execute_on_string): Remove unnecessary check for
8100 integer overflow, noted by Stefan Monnier in
8101 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8102 Remove a FIXME that didn't need fixing.
8103 Simplify the newly-introduced buffer reallocation code.
8105 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8107 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8109 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8111 Integer and memory overflow issues (Bug#9196).
8113 * doc.c (get_doc_string): Rework so that
8114 get_doc_string_buffer_size is the actual buffer size, rather than
8115 being 1 less than the actual buffer size; this makes xpalloc more
8118 * image.c (x_allocate_bitmap_record, cache_image):
8119 * xselect.c (Fx_register_dnd_atom):
8120 Simplify previous changes by using xpalloc.
8122 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8123 since either will do and ptrdiff_t is convenient with xpalloc.
8125 * charset.c (charset_table_size)
8126 (struct charset_sort_data.priority): Now ptrdiff_t.
8127 (charset_compare): Don't overflow if priorities differ greatly.
8128 (Fsort_charsets): Don't assume list length fits in int.
8129 Check for size-calculation overflow when allocating sort data.
8130 (syms_of_charset): Allocate an initial charset table that is
8131 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8133 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8135 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8136 The actual value is always <= INT_MAX, and leaving it unsigned made
8137 overflow checking harder.
8139 * dispextern.h (struct glyph_matrix.rows_allocated)
8140 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8141 with xpalloc. The values are still always <= INT_MAX.
8143 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8145 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8146 (SAFE_NALLOCA): New macro.
8148 * region-cache.c (struct boundary.pos, find_cache_boundary)
8149 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8150 (set_cache_region, invalidate_region_cache)
8151 (revalidate_region_cache, know_region_cache, region_cache_forward)
8152 (region_cache_backward, pp_cache):
8153 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8154 so that ptrdiff_t * can be passed to xpalloc.
8155 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8156 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8157 (pp_cache): Don't assume cache_len fits in int.
8158 * region-cache.h: Adjust extern decls to match.
8160 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8161 EMACS_INT, since either will do, for xpalloc.
8163 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8164 (xnmalloc, xnrealloc, xpalloc): New functions.
8166 * bidi.c (bidi_shelve_header_size): New constant.
8167 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8168 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8170 * bidi.c (bidi_cache_shrink):
8171 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8173 Don't update size of array until after memory allocation succeeds,
8174 because xmalloc/xrealloc may not return.
8175 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8176 now that we have proper integer overflow checking.
8177 (record_overlay_string, overlay_strings): Catch overflows when
8178 calculating size of overlay_str_buf.
8180 * callproc.c (Fcall_process): Check for size overflow when
8181 calculating size of args2.
8182 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8183 Normally we prefer signed values, but sticking with ptrdiff_t would
8184 require adding more-complicated checks.
8186 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8187 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8188 Redo buffer-overflow calculations to avoid integer overflow.

8229 * emacs.c (main): Do not reallocate argv, since there is a null at
8230 the end that can be overwritten, and this way there's no need to
8231 worry about size-calculation overflow.
8232 (sort_args): Check for size-calculation overflow.
8234 * eval.c (init_eval_once, grow_specpdl): Don't update size until

8361 (X_LONG_MIN): New macros.
8362 Use them to make the following changes clearer.
8363 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

8365 future maintainers not to raise the value too much later.
8366 (SELECTION_QUANTUM): Remove, replacing with ...
8367 (selection_quantum): ... new function, which avoids overflow.
8369 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

8387 Don't store size until memory allocation succeeds.
8388 (x_get_window_property): Plug memory leak on memory exhaustion.
8389 Don't double-block input; malloc is safe here. Don't assume 2**34
8390 - 4 fits in unsigned long. Add an xassert to check
8391 XGetWindowProperty overflow. Be more careful about overflow
8392 calculations, and distinguish size from memory overflow better.

8398 in the range -65535 through -1 fit in an X unsigned short.
8399 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into

8401 to report problems with elements; the old code wasn't right anyway.
8402 (x_check_property_data): Check for int overflow; we cannot use
8403 a wider type due to X limits.

8436 * lisp.h (hash_lookup, hash_put):
8437 * minibuf.c (Ftest_completion):
8438 Use ptrdiff_t for hash table indexes, not int (which is too
8439 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8440 32-bit --with-wide-int hosts).

8478 (make_lispy_movement): Use same integer type in forward decl
8479 that is used in the definition.
8480 (read_key_sequence, keyremap_step):
8481 Change bufsize argument back to int, undoing my 2011-03-30 change.
8482 We prefer signed types, and int is wide enough here.
8483 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8484 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow

8486 length, not size_t. Use ptrdiff_t for index, not int.

8516 Prefer int to unsigned where either will do.
8517 (tiff_handler): New function, combining the cores of the
8518 old tiff_error_handler and tiff_warning_handler.
8519 This function is rewritten to use vsnprintf and thereby avoid
8520 stack buffer overflows. It uses only the features of vsnprintf
8521 that are common to both POSIX and native Microsoft.
8522 (tiff_error_handler, tiff_warning_handler): Use it.
8523 (tiff_load, gif_load, imagemagick_load_image):

8527 the integer types that MagickCropImage accepts. Don't assume
8528 Vimagemagick_render_type has a nonnegative value. Don't assume
8529 size_t fits in 'long'.

8544 (handle_single_display_spec): If the display spec is of the form
8545 `(space ...)', and specifies display in the text area, return 2
8547 (try_cursor_movement): Check for the need to scroll more
8548 accurately, and prefer exact match for point under bidi.
8549 Don't advance `row' beyond the last row of the window.
8551 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8552 into disp_prop; all users changed.

8567 buffers, return left-to-right.
8568 (set_cursor_from_row): Consider candidate row a win if its glyph

8570 positioning on the newline at EOL of R2L text within L2R
8571 paragraph, and vice versa.
8572 (try_cursor_movement): Check continued rows, in addition to
8573 continuation rows. Fixes unwarranted scroll when point enters a
8574 continued line of R2L text within an L2R paragraph, or vice versa.
8575 (cursor_row_p): Consider the case of point being equal to
8576 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8577 from the end of a short line to the beginning of a continued line
8578 of R2L text within L2R paragraph.
8579 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8605 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8606 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8607 candidate is selected by the mouse, and that candidate has a
8608 composed character under the mouse.
8610 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8611 coordinates reported by pos-visible-in-window-p for a composed

8622 composed buffer positions.
8624 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8626 * image.c (gif_load): Don't assume that each subimage has the same
8627 dimensions as the base image. Handle disposal method that is
8628 "undefined" by the gif spec (Bug#9335).
8630 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8632 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8635 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8637 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8638 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8639 from an Org mode buffer to a Speedbar frame.
8641 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8642 a composition, take its buffer position from IT->cmp_it.charpos.
8643 Fixes cursor positioning at the beginning of a line that begins
8644 with a composed character.
8646 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8648 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8649 character bidirectional type, use STRONG_L instead. Fixes crashes
8650 in a buffer produced by `describe-categories'.
8652 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8653 members before the level stack, so they would be saved and
8654 restored when copying iterator state. Fixes incorrect reordering
8655 around TABs covered by display properties.
8657 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8659 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
8661 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
8663 * eval.c (internal_condition_case, internal_condition_case_1)
8664 (internal_condition_case_2, internal_condition_case_n):
8665 Remove unnecessary aborts (Bug#9081).
8667 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8669 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8670 has no `load' handler, try opening the file locally. (Bug#9311)
8672 2011-08-16 Ken Brown <kbrown@cornell.edu>
8674 * gmalloc.c: Expand comment.
8676 2011-08-16 Eli Zaretskii <eliz@gnu.org>

8679 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8681 2011-08-16 Ken Brown <kbrown@cornell.edu>
8683 Fix memory allocation problems in Cygwin build (Bug#9273).
8685 * unexcw.c ( __malloc_initialized): Declare external variable.
8686 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8688 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8690 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8692 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8694 [CYGWIN] (special_realloc): New function.
8695 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8696 requests to realloc storage in the static heap.
8698 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8700 * bidi.c (bidi_initialize): Remove unused local.
8702 2011-08-15 Eli Zaretskii <eliz@gnu.org>
8705 * biditype.h: Remove file.
8706 * makefile.w32-in ($(BLD)/bidi.$(O)):
8707 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8709 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8711 * chartab.c: Improve commentary for the uniprop_table API.
8713 * bidi.c (bidi_paragraph_init): Support zero value of
8714 bidi_ignore_explicit_marks_for_paragraph_level.
8715 (bidi_initialize): Use uniprop_table instead of including
8716 biditype.h and bidimirror.h.
8718 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8719 coordinates of the iterator when restoring from ppos_it.
8722 2011-08-14 Kenichi Handa <handa@m17n.org>
8724 * process.c (create_process): Call setup_process_coding_systems
8725 after the pid of the process is set to -1 (Bug#8162).
8727 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8729 * xdisp.c (move_it_in_display_line_to): Don't invoke
8730 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8731 ppos_it. Fixes vertical cursor motion when line beginning is
8732 covered by an image. (Bug#9296)
8734 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8736 * nsterm.h (ns_run_ascript): Declare.
8737 (NSAPP_DATA2_RUNASSCRIPT): Define.
8739 * nsfns.m (as_script, as_result, as_status): New static variables.
8740 (ns_run_ascript): New function.
8741 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8742 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8743 the event loop. Get status from as_status (Bug#7276).
8745 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8746 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8747 the event loop (Bug#7276).
8749 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8751 * gnutls.c (QCgnutls_bootprop_priority)
8752 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8753 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8754 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8755 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8756 (QCgnutls_bootprop_verify_hostname_error)
8757 (QCgnutls_bootprop_callbacks_verify): Rename from
8758 Qgnutls_bootprop_..., all uses changed.

8763 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8765 * xfaces.c (Qframe_set_background_mode): Now static.
8766 * dispextern.h (Qframe_set_background_mode): Remove decl.

8770 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8772 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8773 (Fnetwork_interface_list): Allocate in increments of bytes instead
8774 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8775 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8777 (struct ifflag_def): notrailers is smart on OSX.
8778 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8779 Get hardware address with getifaddrs if available.
8781 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8783 * xdisp.c (iterate_out_of_display_property): xassert that
8784 IT->position is set to within IT->object's boundaries. Break from
8785 the loop as soon as EOB is reached; avoids infloops in redisplay
8786 when IT->position is set up wrongly due to some bug.
8787 Set IT->current to match the bidi iterator unconditionally.
8788 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8789 entry. Force push_it to save on the stack the current
8790 buffer/string position, to be restored by pop_it. Fix flags in
8791 the iterator structure wrt the object coming from a display
8792 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8793 properties. (Bug#9284)
8795 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8797 * fontset.c (fontset_get_font_group): Add proper type checks.

8803 and LC_VERSION_MIN_MACOSX.
8804 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8805 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8807 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8809 * xdisp.c (forward_to_next_line_start): Allow to use the
8810 no-display-properties-and-no-overlays under bidi display.
8811 Set disp_pos in the bidi iterator to avoid searches for display
8812 properties and overlays.
8814 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8816 * editfns.c (Fset_time_zone_rule): Document relationship with the
8819 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8820 the font entity extracted from the cache (Bug#8109).
8822 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8824 * composite.c (autocmp_chars): Don't reset point. That is done by
8825 restore_point_unwind (Bug#5984).
8827 2011-08-07 Juri Linkov <juri@jurta.org>
8829 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8830 to show the arg `TIME' instead of `TIMEVAL'.
8832 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8834 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8835 display property strides EOL and includes a newline, as in
8836 longlines-mode. (Bug#9254)
8837 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8838 word-wrap under bidirectional display. (Bug#9224)
8840 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8841 is non-zero, even if the data buffer is NULL. Fixes a crash in
8842 vertical-motion with longlines-mode. (Bug#9254)
8844 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8846 * bidi.c <bidi_cache_total_alloc>: Now static.
8847 (bidi_initialize): Initialize bidi_cache_total_alloc.
8849 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8852 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8853 amount allocated this far in `bidi_cache_total_alloc'.
8854 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8855 non-zero, only free the data buffer without restoring the cache
8856 contents. All callers changed.
8858 * dispextern.h (bidi_unshelve_cache): Update prototype.
8860 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8861 (move_it_in_display_line, move_it_to)
8862 (move_it_vertically_backward, move_it_by_lines): Replace the call
8863 to xfree to an equivalent call to bidi_unshelve_cache.
8864 (move_it_in_display_line_to): Fix logic of returning
8865 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8867 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8869 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8870 came from a string character with a `cursor' property. (Bug#9229)
8872 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8874 * Makefile.in (LIB_PTHREAD): New variable.
8875 (LIBES): Add LIB_PTHREAD (Bug#9216).
8877 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8878 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8880 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8882 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8884 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8886 * xterm.c (x_find_topmost_parent): New function.
8887 (x_set_frame_alpha): Find topmost parent window with
8888 x_find_topmost_parent and set the property there also (bug#9181).
8889 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8891 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8893 * callproc.c (Fcall_process): Avoid vfork clobbering
8894 the local vars buffer, coding_systems, current_dir.
8896 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8898 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8900 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8902 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8903 so that it is not optimized away.
8905 * xdisp.c (compute_display_string_pos): Remove unused local.
8907 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8909 Fix slow cursor motion and scrolling in large buffers with
8910 selective display, like Org Mode buffers. (Bug#9218)
8912 * dispextern.h (struct bidi_it): New member disp_prop_p.
8914 * xdisp.c: Remove one-slot cache of display string positions.
8915 (compute_display_string_pos): Accept an additional argument
8916 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8917 for a display string or property. If found, set DISP_PROP_P
8920 * bidi.c (bidi_fetch_char): Accept an additional argument
8921 DISP_PROP_P, and pass it to compute_display_string_pos.
8922 Only handle text covered by a display string if DISP_PROP_P is returned
8923 non-zero. All callers of bidi_fetch_char changed.
8925 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8927 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8929 2010-12-03 Don March <don@ohspite.net>
8931 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8932 last character M-[char] is translated to ESC [char] (bug#7541).
8934 2011-08-02 Kenichi Handa <handa@m17n.org>
8936 * lisp.h (uniprop_table): Extern it.
8938 * chartab.c (uniprop_table): Make it non-static.
8940 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8942 * xdisp.c (forward_to_next_line_start): Accept additional argument
8943 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8945 (reseat_at_next_visible_line_start): Use the bidi iterator state
8946 returned by forward_to_next_line_start to restore the state of
8947 it->bidi_it after backing up to previous newline. (Bug#9212)
8949 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8951 * regex.c (re_comp): Protoize.
8952 (re_exec): Fix return type.
8953 (regexec): Fix type of `ret'. (Bug#9203)
8955 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8957 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8958 This is needed if max-image-size is a floating-point number.
8960 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8962 * print.c (print_object): Print empty symbol as ##.
8964 * lread.c (read1): Read ## as empty symbol.
8966 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8968 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8969 setting frame foreground color (Bug#9175).
8970 (x_set_background_color): Likewise.
8972 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8973 contents (Bug#9176).
8974 (EmacsTooltip -init): Remove bezels and add shadows to
8977 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8978 or scroll bar (Bug#8470).
8980 * nsfont.m (nsfont_open): Remove assignment to voffset and
8981 unnecessary vars hshink, expand, hd, full_height, min_height.
8982 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8984 * nsterm.h (nsfont_info): Remove voffset field.
8986 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8988 Implement strike-through and overline on NextStep (Bug#8863).
8990 * nsfont.m (nsfont_open): Use underline position provided by font,
8991 instead of hard-coded value of 2.
8992 (nsfont_draw): Call ns_draw_text_decoration instead.
8994 * nsterm.h: Add declaration for ns_draw_text_decoration.
8996 * nsterm.m (ns_draw_text_decoration): New function for drawing
8997 underline, overline, and strike-through.
8998 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8999 ns_draw_text_decoration. Change treatment of cursor drawing to
9000 accommodate underlining, etc.
9002 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9004 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9007 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9009 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9010 Without this fix, if a signal arrives just after memory fills up,
9011 'malloc' might be invoked reentrantly.
9013 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9014 In other words, assume that every image size is allowed, on non-X
9015 hosts. This assumption is probably wrong, but it lets Emacs compile.
9017 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9019 * regex.c (re_iswctype): Convert return values to boolean.
9021 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9023 * xdisp.c (compute_display_string_pos): Don't use cached display
9024 string position if the buffer had its restriction changed.
9027 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9029 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9031 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9033 Integer signedness and overflow and related fixes. (Bug#9079)
9035 * bidi.c: Integer size and overflow fixes.
9036 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9037 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9038 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9039 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9040 (bidi_find_other_level_edge):
9041 Use ptrdiff_t instead of EMACS_INT where either will do.
9042 This works better on 32-bit hosts configured --with-wide-int.
9043 (bidi_cache_ensure_space): Check for size-calculation overflow.
9044 Use % rather than repeated addition, for better worst-case speed.
9045 Don't set bidi_cache_size until after xrealloc returns, because it
9047 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9048 (bidi_cache_ensure_space): Also check that the bidi cache size
9049 does not exceed that of the largest Lisp string or buffer. See Eli
9050 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9052 * alloc.c (__malloc_size_t): Remove.
9053 All uses replaced by size_t. See Andreas Schwab's note
9054 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9056 * image.c: Improve checking for integer overflow.
9057 (check_image_size): Assume that f is nonnull, since
9058 it is always nonnull in practice. This is one less thing to
9059 worry about when checking for integer overflow later.
9060 (x_check_image_size): New function, which checks for integer
9061 overflow issues inside X.
9062 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9063 This removes the need for a memory_full check.
9064 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9065 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9066 (xbm_read_bitmap_data): Change locals back to 'int', since
9067 their values must fit in 'int'.
9068 (xpm_load_image, png_load, tiff_load):
9069 Invoke x_create_x_image_and_pixmap earlier,
9070 to avoid much needless work if the image is too large.
9071 (tiff_load): Treat overly large images as if
9072 x_create_x_image_and_pixmap failed, not as malloc failures.
9073 (gs_load): Use x_check_image_size.
9075 * gtkutil.c: Omit integer casts.
9076 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9077 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9079 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9081 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9082 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9083 would wrongly return t on a 64-bit host.
9085 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9086 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9087 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9088 and therefore cause GCC to emit a bogus diagnostic in some cases.
9090 * image.c: Integer signedness and overflow and related fixes.
9091 This is not an exhaustive set of fixes, but it's time to
9092 record what I've got.
9093 (lookup_pixel_color, check_image_size): Remove redundant decls.
9094 (check_image_size): Don't assume that arbitrary EMACS_INT values
9095 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9096 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9097 (tiff_load, imagemagick_load_image):
9098 Check for overflow in size calculations.
9099 (x_create_x_image_and_pixmap): Remove unnecessary test for
9100 xmalloc returning NULL; that can't happen.
9101 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9102 (xpm_color_bucket): Use better integer hashing function.
9103 (xpm_cache_color): Don't possibly over-allocate memory.
9104 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9105 (gif_memory_source):
9106 Use ptrdiff_t, not int or size_t, to record sizes.
9107 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9108 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9109 either works, as we prefer signed integers.
9110 (tiff_read_from_memory, tiff_write_from_memory):
9111 Return tsize_t, not size_t, since that's what the TIFF API wants.
9112 (tiff_read_from_memory): Don't fail simply because the read would
9113 go past EOF; instead, return a short read.
9114 (tiff_load): Omit no-longer-needed casts.
9115 (Fimagemagick_types): Don't assume size fits into 'int'.
9117 Improve hashing quality when configured --with-wide-int.
9118 * fns.c (hash_string): New function, taken from sxhash_string.
9119 Do not discard information about ASCII character case; this
9120 discarding is no longer needed.
9121 (sxhash-string): Use it. Change sig to match it. Caller changed.
9122 * lisp.h: Declare it.
9123 * lread.c (hash_string): Remove, since we now use fns.c's version.
9124 The fns.c version returns a wider integer if --with-wide-int is
9125 specified, so this should help the quality of the hashing a bit.
9127 * emacs.c: Integer overflow minor fix.
9128 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9129 Define only if GNU_LINUX.
9130 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9132 * dispnew.c: Integer signedness and overflow fixes.
9133 Remove unnecessary forward decls, that were a maintenance hassle.
9134 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9136 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9137 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9138 (prepare_desired_row, line_draw_cost):
9139 Use int, not unsigned, where either works.
9140 (save_current_matrix, restore_current_matrix):
9141 Use ptrdiff_t, not size_t, where either works.
9142 (init_display): Check for overflow more accurately, and without
9143 relying on undefined behavior.
9145 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9146 Remove, replacing with the new symbols in lisp.h. All uses changed.
9147 * fileio.c (make_temp_name):
9148 * filelock.c (lock_file_1, lock_file):
9149 * xdisp.c (message_dolog):
9150 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9151 Use pMd etc. instead.
9152 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9153 replacing the pWIDE etc. symbols removed from editfns.c.
9155 * keyboard.h (num_input_events): Now uintmax_t.
9156 This is (very slightly) less likely to mess up due to wraparound.
9159 * buffer.c: Integer signedness fixes.
9160 (alloc_buffer_text, enlarge_buffer_text):
9161 Use ptrdiff_t rather than size_t when either will do, as we prefer
9164 * alloc.c: Integer signedness and overflow fixes.
9165 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9166 (__malloc_size_t): Default to size_t, not to int.
9167 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9168 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9169 Prefer ptrdiff_t to size_t when either would do, as we prefer
9171 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9172 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9173 Now const. Initialize with values that are in range even if char
9175 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9176 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9177 These functions do the right thing with sizes > 2**32.
9178 (check_depth): Now ptrdiff_t, not int.
9179 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9180 Adjust to new way of storing sizes. Check for size overflow bugs
9182 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9183 slightly wrong anyway, as it missed one instance of
9184 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9185 (refill_memory_reserve): Omit needless cast to size_t.
9186 (mark_object_loop_halt): Mark as externally visible.
9188 * xselect.c: Integer signedness and overflow fixes.
9189 (Fx_register_dnd_atom, x_handle_dnd_message):
9190 Use ptrdiff_t, not size_t, since we prefer signed.
9191 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9192 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9193 x_dnd_atoms_size and x_dnd_atoms_length.
9195 * doprnt.c: Prefer signed to unsigned when either works.
9197 * doprnt.c (doprnt):
9199 * xdisp.c (vmessage):
9200 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9201 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9202 prefer signed arithmetic to avoid comparison confusion.
9203 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9204 but is a bit tricky.
9206 Assume freestanding C89 headers, string.h, stdlib.h.
9207 * data.c, doprnt.c, floatfns.c, print.c:
9208 Include float.h unconditionally.
9209 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9210 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9211 * regex.c: Likewise for stddef.h, string.h.
9212 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9213 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9214 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9215 (STDC_HEADERS): Remove obsolete defines.
9216 * sysdep.c: Include limits.h unconditionally.
9218 Assume support for memcmp, memcpy, memmove, memset.
9219 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9220 * regex.c (memcmp, memcpy):
9221 Remove; we assume C89 now.
9223 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9224 (__malloc_safe_bcopy): Remove; no longer needed.
9226 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9227 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9228 well either way, and we prefer signed to unsigned.
9230 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9232 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9233 closes the connection while we're reading (bug#9182).
9235 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9237 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9238 are specified (Bug#9168).
9240 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9242 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9243 Found by GCC static checking and --with-wide-int on a 32-bit host.
9245 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9247 * xdisp.c (compute_display_string_pos): Fix logic of caching
9248 previous display string position. Initialize cached_prev_pos to
9249 -1. Fixes slow-down at the beginning of a buffer.
9251 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9253 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9254 for attrs[LFACE_FONTSET_INDEX].
9256 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9258 * xml.c (parse_region): Remove unused local
9259 that was recently introduced.
9261 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9263 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9264 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9266 * xdisp.c (move_it_in_display_line_to): Record the best matching
9267 position for TO_CHARPOS while scanning the line, and restore it on
9268 exit if none of the characters scanned was an exact match.
9269 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9270 when exact match is impossible due to invisible text, and the
9271 lines are truncated.
9273 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9275 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9278 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9280 Fix a significant slow-down of cursor motion with C-n, C-p,
9281 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9282 auto-repeat under bidi redisplay in fontified buffers.
9283 * xdisp.c (compute_stop_pos_backwards): New function.
9284 (next_element_from_buffer): Call compute_stop_pos_backwards to
9285 find a suitable prev_stop when we find ourselves before
9287 (reseat): Don't look for prev_stop, as that could mean a very long
9289 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9290 <cached_disp_overlay_modiff>: Cache for last found display string
9292 (compute_display_string_pos): Return the cached position if asked
9293 about the same buffer in the same area of character positions, and
9294 the buffer wasn't changed since the time the display string
9295 position was cached.
9297 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9299 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9300 is an integer, which is important for empty lines. (Bug#9149)
9302 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9304 * frame.c (Fmodify_frame_parameters): In tty case, update the
9305 default face if necessary (Bug#4238).
9307 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9309 * editfns.c (Fstring_to_char): No need to explain what a character
9310 is in the docstring (Bug#6576).
9312 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9314 * xml.c (parse_region): Make sure we always return a tree.
9316 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9318 * xml.c (parse_region): If a document contains only comments,
9321 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9323 * xml.c (make_dom): Return comments, too.
9325 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9328 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9329 and the surrounding thread.
9330 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9331 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9332 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9334 * s/openbsd.h (BROKEN_SIGIO): Define.
9335 * unexelf.c (unexec) [__OpenBSD__]:
9336 Don't update the .mdebug section of the Alpha COFF symbol table.
9338 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9340 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9343 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9345 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9346 This fixes some race conditions on the permissions of any newly
9349 * alloc.c (valid_pointer_p): Use pipe, not open.
9350 This fixes some permissions issues when debugging.
9352 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9353 If fchown fails to set both uid and gid, try to set just gid,
9354 as that is sometimes allowed. Adjust the file's mode to eliminate
9355 setuid or setgid bits that are inappropriate if fchown fails.
9357 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9359 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9360 to compare Lisp_Objects.
9361 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9362 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9363 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9365 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9367 * lread.c (read_integer): Unread even EOF character.
9368 (read1): Likewise. Properly record start position of symbol.
9370 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9371 symbol character follows.
9373 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9375 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9376 This works around a problem with the previous change to Fcopy_file.
9377 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9378 and without this change, GCC might complain about discarding
9379 fchown's return value.
9381 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9383 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9385 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9387 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9389 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9391 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9392 it's used from the C level.
9394 * process.c: Use the same condition for POLL_FOR_INPUT in both
9395 keyboard.c and process.c (bug#1858).
9397 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9399 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9400 (Fgnutls_boot): Use it.
9402 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9404 * doc.c (Fsubstitute_command_keys): Revert last change.
9406 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9408 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9409 quotes the next character, and doesn't affect other longer
9410 sequences (bug#8935).
9412 * lread.c (syms_of_lread): Clarify that is isn't only
9413 `eval-buffer' and `eval-defun' that's affected by
9414 `lexical-binding' (bug#8460).
9416 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9418 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9419 bidi redisplay when a line includes both an image and is truncated.
9421 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9423 Fix minor problems found by static checking.
9424 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9425 (elsz): Now a signed constant, not a size_t var. We prefer signed
9426 types to unsigned, to avoid integer comparison confusion. Without
9427 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9428 "cannot optimize loop, the loop counter may overflow", a symptom
9430 * indent.c (Fvertical_motion): Mark locals as initialized.
9431 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9433 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9435 * search.c (Fre_search_backward): Mention `case-fold-search' in
9436 all the re_search_* functions (bug#8138).
9438 * keyboard.c (Fopen_dribble_file): Document when the file is
9441 2011-07-14 Eli Zaretskii <eliz@gnu.org>
9443 * bidi.c (bidi_dump_cached_states): Fix format of displaying
9446 Support bidi reordering of display and overlay strings.
9447 * xdisp.c (compute_display_string_pos)
9448 (compute_display_string_end): Accept additional argument STRING.
9449 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9450 (reseat_to_string): Initialize bidi_it->string.s and
9451 bidi_it->string.schars.
9452 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9453 NULL (avoids a crash in bidi_paragraph_init).
9454 Initialize itb.string.lstring.
9455 (init_iterator): Call bidi_init_it only of a valid
9456 buffer position was specified. Initialize paragraph_embedding to
9458 (reseat_to_string): Initialize the bidi iterator.
9459 (display_string): If we need to ignore text properties of
9460 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9461 original value of -1 will not work with bidi.)
9462 (compute_display_string_pos): First arg is now struct
9463 `text_pos *'; all callers changed. Support display properties on
9465 (compute_display_string_end): Support display properties on Lisp
9467 (init_iterator, reseat_1, reseat_to_string): Initialize the
9468 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9469 when iterating on a string not from display properties).
9470 (compute_display_string_pos, compute_display_string_end):
9471 Fix calculation of the object to scan. Fixes an error when using
9473 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9474 base_level_stop; instead, set base_level_stop to BEGV.
9475 Fixes crashes in vertical-motion.
9476 (next_element_from_buffer): Improve commentary for when
9477 the iterator is before prev_stop.
9478 (init_iterator): Initialize bidi_p from the default value of
9479 bidi-display-reordering, not from buffer-local value. Use the
9480 buffer-local value only if initializing for buffer iteration.
9481 (handle_invisible_prop): Support invisible properties on strings
9482 that are being bidi-reordered.
9483 (set_iterator_to_next): Support bidi reordering of C strings and
9485 (next_element_from_string): Support bidi reordering of Lisp
9487 (handle_stop_backwards): Support Lisp strings as well.
9488 (display_string): Support display of R2L glyph rows.
9489 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9490 (init_iterator): Don't initialize it->bidi_p for strings
9492 (reseat_to_string): Initialize it->bidi_p for strings here.
9493 (next_element_from_string, next_element_from_c_string)
9494 (next_element_from_buffer): Add xassert's for correspondence
9495 between IT's object being iterated and it->bidi_it.string
9497 (face_before_or_after_it_pos): Support bidi iteration.
9498 (next_element_from_c_string): Handle the case of the first string
9499 character that is not the first one in the visual order.
9500 (get_visually_first_element): New function, refactored from common
9501 parts of next_element_from_buffer, next_element_from_string, and
9502 next_element_from_c_string.
9503 (tool_bar_lines_needed, redisplay_tool_bar)
9504 (display_menu_bar): Force left-to-right direction. Add a FIXME
9505 comment for making that be controlled by a user option.
9506 (push_it, pop_it): Save and restore the state of the
9507 bidi iterator. Save and restore the bidi_p flag.
9508 (pop_it): Iterate out of display property for string iteration as
9510 (iterate_out_of_display_property): Support iteration over strings.
9511 (handle_single_display_spec): Set up it->bidi_it for iteration
9512 over a display string, and call bidi_init_it.
9513 (handle_single_display_spec, next_overlay_string)
9514 (get_overlay_strings_1, push_display_prop): Set up the bidi
9515 iterator for displaying display or overlay strings.
9516 (forward_to_next_line_start): Don't use the shortcut if
9518 (back_to_previous_visible_line_start): If handle_display_prop
9519 pushed the iterator stack, restore the internal state of the bidi
9520 iterator by calling bidi_pop_it same number of times.
9521 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9522 and we are bidi-iterating, don't decrement the iterator position;
9523 instead, set the first_elt flag in the bidi iterator, to produce
9525 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9526 (push_display_prop): xassert that we are iterating a buffer.
9527 (push_it, pop_it): Save and restore paragraph_embedding member.
9528 (handle_single_display_spec, next_overlay_string)
9529 (get_overlay_strings_1, reseat_1, reseat_to_string)
9530 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9531 correctly. Don't assume unibyte strings are not bidi-reordered.
9532 (compute_display_string_pos)
9533 (compute_display_string_end): Fix handling the case of C string.
9534 (push_it, pop_it): Save and restore from_disp_prop_p.
9535 (handle_single_display_spec, push_display_prop): Set the
9536 from_disp_prop_p flag.
9537 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
9538 (pop_it): Call iterate_out_of_display_property only if we are
9539 popping after iteration over a string that came from a display
9540 property. Fix a typo in popping stretch info. Add an assertion
9541 for verifying that the iterator position is in sync with the bidi
9543 (handle_single_display_spec, get_overlay_strings_1)
9544 (push_display_prop): Fix initialization of paragraph direction for
9545 string when that of the parent object is not yet determined.
9546 (reseat_1): Call bidi_init_it to resync the bidi
9547 iterator with IT's position. (Bug#7616)
9548 (find_row_edges): If ROW->start.pos gives position
9549 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
9550 (handle_stop, back_to_previous_visible_line_start, reseat_1):
9551 Reset the from_disp_prop_p flag.
9552 (SAVE_IT, RESTORE_IT): New macros.

9556 (move_it_to, move_it_vertically_backward, move_it_by_lines)
9557 (try_scrolling, redisplay_window, display_line): Use them when
9558 saving a temporary copy of the iterator and restoring it back.
9559 (back_to_previous_visible_line_start, reseat_1)
9560 (init_iterator): Empty the bidi cache "stack".
9561 (move_it_in_display_line_to): If iterator ended up at
9562 EOL, but we never saw any buffer positions smaller than
9563 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9564 motion in bidi-reordered lines.
9565 (move_it_in_display_line_to): Record prev_method and prev_pos
9566 immediately before the call to set_iterator_to_next. Fixes cursor
9567 motion in bidi-reordered lines with stretch glyphs and strings
9568 displayed in margins. (Bug#8133) (Bug#8867)
9569 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9571 (pos_visible_p): Support positions in bidi-reordered lines.

9997 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9998 subseconds part to the entropy, as that's a bit more random.

10000 in general we prefer signed. When given a limit, use a
10001 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10002 latter isn't right if USE_2_TAGS_FOR_INTS.

10021 * buffer.c (Foverlay_put): Say what the return value is

10149 * eval.c (struct backtrace): Simplify and port the data structure.
10150 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10151 signed bit field, as this assumption is not portable and it makes
10152 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10153 "char debug_on_exit : 1" as this is not portable either; instead,
10154 use the portable "unsigned int debug_on_exit : 1". Remove unused
10155 member evalargs. Remove obsolete comments about cc bombing out.

10345 (read1): Check for integer overflow in radices, and in
10346 read-circle numbers.

10348 (Fload, openp, read_buffer_size, read1)
10349 (substitute_object_recurse, read_vector, read_list, map_obarray):

10373 The following patches are for when GLYPH_DEBUG && !XASSERT.

10390 on undefined behavior with wrong number of arguments.
10391 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10392 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10393 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10394 since we're not interested in debugging glyphs with old libraries.
10395 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10396 GCC 4.6.0's static checking.
10398 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

10437 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10438 (x_session_initialize): Do not assume string length fits in int.
10440 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10441 This is unlikely, but can occur if DPI is outlandish.
10443 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):

10467 * lread.c (intern, intern_c_string):
10468 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

10471 * keyboard.c (parse_tool_bar_item):
10472 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10474 * font.c: Don't assume string length fits in int.
10475 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10476 Use ptrdiff_t, not int.
10477 (font_intern_prop): Don't assume string length fits in int.
10478 Don't assume integer property fits in fixnum.
10479 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10481 * filelock.c: Fix some buffer overrun and integer overflow issues.
10482 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10483 Reformulate so as not to need the command string.
10484 Invoke gzip -cd rather than gunzip, as it's more portable.
10485 (lock_info_type, lock_file_1, lock_file):
10486 Don't assume pid_t and time_t fit in unsigned long.
10487 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10488 (current_lock_owner): Prefer signed type for sizes.
10489 Use memcpy, not strncpy, where memcpy is what is really wanted.
10490 Don't assume (via atoi) that time_t and pid_t fit in int.
10491 Check for time_t and/or pid_t out of range, e.g., via a network share.
10492 Don't alloca where an auto var works fine.
10494 * fileio.c: Fix some integer overflow issues.
10495 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10496 Don't assume string length fits in int.
10497 (directory_file_name): Don't assume string length fits in long.
10498 (make_temp_name): Don't assume pid fits in int, or that its print
10499 length is less than 20.
10501 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10503 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10505 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10507 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10508 We prefer signed integers, even for size calculations.
10510 * emacs.c: Don't assume string length fits in 'int'.
10511 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10512 (main): Don't invoke strlen when not needed.
10514 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10515 (XD_DEBUG_MESSAGE): Don't waste a byte.
10517 * callproc.c (getenv_internal_1, getenv_internal)
10518 (Fgetenv_internal):
10519 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10521 * lread.c (invalid_syntax): Omit length argument.
10522 All uses changed. This doesn't fix a bug, but it simplifies the
10523 code away from its former Hollerith-constant appearance, and it's
10524 one less 'int' to worry about when looking at integer-overflow issues.
10525 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10527 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10528 This didn't break anything, but it didn't help either.
10529 It's confusing to put a bogus integer in a place where the actual
10530 value does not matter.
10531 (LIST_END_P): Remove unused macro and its bogus comment.
10532 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10534 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10535 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10537 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10538 We prefer signed types, and the value cannot exceed the EMACS_INT
10539 range anyway (because otherwise the length would not be representable).
10540 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10541 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10542 This avoids a GCC warning when WIDE_EMACS_INT.
10544 * indent.c (sane_tab_width): New function.
10545 (current_column, scan_for_column, Findent_to, position_indentation)
10546 (compute_motion): Use it. This is just for clarity.
10547 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10549 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10551 * lisp.h (lint_assume): New macro.
10552 * composite.c (composition_gstring_put_cache):
10553 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10555 * editfns.c, insdel.c:
10556 Omit unnecessary forward decls, to simplify future changes.
10558 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10560 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10562 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10563 Use much-faster test for byte-length change.
10564 Don't assume string byte-length fits in 'int'.
10565 Check that character arg fits in 'int'.
10566 (mapcar1): Declare byte as byte, for clarity.
10568 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10570 * fns.c (concat): Catch string overflow earlier.
10571 Do not rely on integer wraparound.
10573 * dispextern.h (struct it.overlay_strings_charpos)
10574 (struct it.selective): Now EMACS_INT, not int.
10575 * xdisp.c (forward_to_next_line_start)
10576 (back_to_previous_visible_line_start)
10577 (reseat_at_next_visible_line_start, next_element_from_buffer):
10578 Don't arbitrarily truncate the value of 'selective' to int.
10580 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10582 * composite.c: Don't truncate sizes to 'int'.
10583 (composition_gstring_p, composition_reseat_it)
10584 (composition_adjust_point): Use EMACS_INT, not int.
10585 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10586 not EMACS_UINT, for indexes.
10588 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10590 * buffer.c: Include <verify.h>.
10591 (struct sortvec.priority, struct sortstr.priority):
10592 Now EMACS_INT, not int.
10593 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10594 (struct sortstr.size, record_overlay_string)
10595 (struct sortstrlist.size, struct sortlist.used):
10596 Don't truncate size to int.
10597 (record_overlay_string): Check for size-calculation overflow.
10598 (init_buffer_once): Check at compile-time, not run-time.
10600 2011-06-22 Jim Meyering <meyering@redhat.com>
10602 Don't leak an XBM-image-sized buffer
10603 * image.c (xbm_load): Free the image buffer after using it.
10605 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10608 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10609 that Sun C diagnosed.
10610 * fns.c (secure_hash): Fix pointer signedness issue.
10611 * intervals.c (static_offset_intervals): New function.
10612 (offset_intervals): Use it.
10614 2011-06-21 Leo Liu <sdl.web@gmail.com>
10617 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10620 * fns.c (secure_hash): Rename from crypto_hash_function and change
10621 the first arg to accept symbols.
10622 (Fsecure_hash): New primitive.
10623 (syms_of_fns): New symbols.
10625 2011-06-20 Deniz Dogan <deniz@dogan.se>
10627 * process.c (Fset_process_buffer): Clarify return value in
10630 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10632 * dispnew.c (add_window_display_history): Use BVAR.
10634 * xdisp.c (debug_method_add): Use BVAR.
10635 (check_window_end, dump_glyph_matrix, dump_glyph)
10636 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10638 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10641 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10642 check till after the cache is created in init_frame_faces.
10644 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10646 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10648 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10650 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10651 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10652 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10654 Improve buffer-overflow checking (Bug#8873).
10655 * fileio.c (Finsert_file_contents):
10656 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10657 Remove the old (too-loose) buffer overflow checks.
10658 They weren't needed, since make_gap checks for buffer overflow.
10659 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10660 The old code merely checked for Emacs fixnum overflow, and relied
10661 on undefined (wraparound) behavior. The new code avoids undefined
10662 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10664 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10665 Tune. Don't use wider integers than needed. Don't use alloca.
10666 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10668 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10670 * insdel.c, lisp.h (buffer_overflow): New function.
10671 (insert_from_buffer_1, replace_range, replace_range_2):
10672 * insdel.c (make_gap_larger):
10673 * editfns.c (Finsert_char):
10674 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10676 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10678 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10680 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10682 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10683 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10685 * fileio.c: Don't assume EMACS_INT fits in off_t.
10686 (emacs_lseek): New static function.
10687 (Finsert_file_contents, Fwrite_region): Use it.
10688 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10690 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10692 * fns.c: Don't overflow int when computing a list length.
10693 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10694 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10695 truncation on 64-bit hosts. Check for QUIT every
10696 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10697 faster and is responsive enough.
10698 (Flength): Report an error instead of overflowing an integer.
10699 (Fsafe_length): Return a float if the value is not representable
10700 as a fixnum. This shouldn't happen except in contrived situations.
10701 (Fnthcdr, Fsort): Don't assume list length fits in int.
10702 (Fcopy_sequence): Don't assume vector length fits in int.
10704 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10705 (header_size, word_size): New constants.
10706 (allocate_vectorlike): Don't check size overflow here.
10707 (allocate_vector): Check it here instead, since this is the only
10708 caller of allocate_vectorlike that could cause overflow.
10709 Check that the new vector's length is representable as a fixnum.
10711 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10712 The previous code was bogus. For example, next_almost_prime (32)
10713 returned 39, which is undesirable as it is a multiple of 3; and
10714 next_almost_prime (24) returned 25, which is a multiple of 5 so
10715 why was the code bothering to check for multiples of 7?
10717 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10719 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10721 Variadic C functions now count arguments with ptrdiff_t.
10722 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10723 Back then I didn't know that the Emacs coding style prefers signed int.
10724 Also, in the meantime I found a few more instances where arguments
10725 were being counted with int, which may truncate counts on 64-bit
10726 machines, or EMACS_INT, which may be unnecessarily wide.
10727 * lisp.h (struct Lisp_Subr.function.aMANY)
10728 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10729 Arg counts are now ptrdiff_t, not size_t.
10730 All variadic functions and their callers changed accordingly.
10731 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10732 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10733 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10734 * callint.c (Fcall_interactively): Check arg count for overflow,
10735 to avoid potential buffer overrun. Use signed char, not 'int',
10736 for 'varies' array, so that we needn't bother to check its size
10737 calculation for overflow.
10738 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10739 * eval.c (apply_lambda):
10740 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10741 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10742 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10744 * callint.c (Fcall_interactively): Don't use index var as event count.
10746 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10747 * mem-limits.h (SIZE): Remove; no longer used.
10749 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10751 Remove unnecessary casts.
10752 * xterm.c (x_term_init):
10753 * xfns.c (x_set_border_pixel):
10754 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10755 These aren't needed now that we assume ANSI C.
10757 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10758 It's more likely to cause problems (due to unsigned overflow)
10761 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10763 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10765 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10767 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10769 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10771 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10773 GLYPH_CODE_FACE returns EMACS_INT, not int.
10774 * dispextern.h (merge_faces):
10775 * xfaces.c (merge_faces):
10776 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10777 Don't assume EMACS_INT fits in int.
10779 * character.h (CHAR_VALID_P): Remove unused parameter.
10780 * fontset.c, lisp.h, xdisp.c: All uses changed.
10782 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10784 * fns.c (concat): Minor tuning based on overflow analysis.
10785 This doesn't fix any bugs. Use int to hold character, instead
10786 of constantly refetching from Emacs object. Use XFASTINT, not
10787 XINT, for value known to be a character. Don't bother comparing
10788 a single byte to 0400, as it's always less.
10790 * floatfns.c (Fexpt):
10791 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10793 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10796 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10798 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10799 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10800 incorrectly succeed when S was a string, because 4294967386 was
10801 truncated before it was used.
10803 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10804 Otherwise, an out-of-range integer could cause undefined behavior
10807 * composite.c: Use int, not EMACS_INT, for characters.
10808 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10809 EMACS_INT, for values that are known to be in character range.
10810 This doesn't fix any bugs but is the usual style inside Emacs and
10811 may generate better code on 32-bit machines.
10813 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10814 This is for reasons similar to the recent CHAR_STRING fix.
10815 * charset.c (Fencode_char): Check that character arg is actually
10816 a character. Pass an int to ENCODE_CHAR.
10817 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10818 wider than 'int', as a compile-time check to prevent future regressions
10821 * character.c (char_string): Remove unnecessary casts.
10823 Make sure a 64-bit char is never passed to CHAR_STRING.
10824 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10825 by silently ignoring the top 32 bits, allowing some values
10826 that were far too large to be valid characters.
10827 * character.h: Include <verify.h>.
10828 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10829 arguments are no wider than unsigned, as a compile-time check
10830 to prevent future regressions in this area.
10832 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10833 (Fsubst_char_in_region):
10835 * xdisp.c (decode_mode_spec_coding):
10836 Adjust to CHAR_STRING's new requirement.
10837 * editfns.c (Finsert_char, Fsubst_char_in_region):
10838 * fns.c (concat): Check that character args are actually
10839 characters. Without this test, these functions did the wrong
10840 thing with wildly out-of-range values on 64-bit hosts.
10842 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10843 These casts should not be needed on 32-bit hosts, either.
10844 * keyboard.c (read_char):
10845 * lread.c (Fload): Remove casts to unsigned.
10847 * lisp.h (UNSIGNED_CMP): New macro.
10848 This fixes comparison bugs on 64-bit hosts.
10849 (ASCII_CHAR_P): Use it.
10850 * casefiddle.c (casify_object):
10851 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10852 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10853 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10854 * dispextern.h (FACE_FROM_ID):
10855 * keyboard.c (read_char): Use UNSIGNED_CMP.
10857 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10858 not to EMACS_INT, to avoid GCC warning.
10860 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10862 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10863 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10864 isn't needed on 32-bit machines.
10866 * buffer.c (Fgenerate_new_buffer_name):
10867 Use EMACS_INT for count, not int.
10868 (advance_to_char_boundary): Return EMACS_INT, not int.
10870 * data.c (Qcompiled_function): Now static.
10872 * window.c (window_body_lines): Now static.
10874 * image.c (gif_load): Rename local to avoid shadowing.
10876 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10877 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10878 * alloc.c (make_save_value): Integer argument is now of type
10879 ptrdiff_t, not int.
10880 (mark_object): Use ptrdiff_t, not int.
10881 * lisp.h (pD): New macro.
10882 * print.c (print_object): Use it.
10884 * alloc.c: Use EMACS_INT, not int, to count objects.
10885 (total_conses, total_markers, total_symbols, total_vector_size)
10886 (total_free_conses, total_free_markers, total_free_symbols)
10887 (total_free_floats, total_floats, total_free_intervals)
10888 (total_intervals, total_strings, total_free_strings):
10889 Now EMACS_INT, not int. All uses changed.
10890 (Fgarbage_collect): Compute overall total using a double, so that
10891 integer overflow is less likely to be a problem. Check for overflow
10892 when converting back to an integer.
10893 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10894 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10895 These were 'int' variables that could overflow on 64-bit hosts;
10896 they were never used, so remove them instead of repairing them.
10897 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10898 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10899 Previously, this ceilinged at INT_MAX, but that doesn't work on
10901 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10903 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10904 (allocate_vectorlike): Check for ptrdiff_t overflow.
10905 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10906 when a (possibly-narrower) signed value would do just as well.
10907 We prefer using signed arithmetic, to avoid comparison confusion.
10909 * alloc.c: Catch some string size overflows that we were missing.
10910 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,

11351 (slurp_file): Check that file size fits in both size_t (for
11352 malloc) and ptrdiff_t (for sanity and safety).
11354 * fileio.c (Fverify_visited_file_modtime): Avoid time overflow
11355 if b->modtime has its maximal value.
11357 * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.
11359 Don't assume time_t can fit into int.
11360 * buffer.h (struct buffer.modtime): Now time_t, not int.
11361 * fileio.c (Fvisited_file_modtime): No need for time_t cast now.
11362 * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
11364 Minor fixes for signed vs unsigned integers.
11365 * character.h (MAYBE_UNIFY_CHAR):
11366 * charset.c (maybe_unify_char):
11367 * keyboard.c (read_char, reorder_modifiers):
11368 XINT -> XFASTINT, since the integer must be nonnegative.
11369 * ftfont.c (ftfont_spec_pattern):
11370 * keymap.c (access_keymap, silly_event_symbol_error):
11371 XUINT -> XFASTINT, since the integer must be nonnegative.

11373 since it makes no difference and we prefer signed.
11374 * keyboard.c (record_char): Use XUINT when all the neighbors do.
11375 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

11422 code. Minor doc-string fixes.
11424 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
11426 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
11427 Do not assume that spare memory exists; that assumption is valid
11428 only if SYSTEM_MALLOC.
11429 (LARGE_REQUEST): New macro, so that the issue of large requests
11430 is separated from the issue of spare memory.
11432 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
11434 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

11460 New error handlers.
11461 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
11462 Obey Vx_select_enable_clipboard_manager. Catch errors in
11463 x_clipboard_manager_save (Bug#8779).
11464 (Vx_select_enable_clipboard_manager): New variable.
11465 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11467 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11469 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11471 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11473 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap

11486 (bidi_cache_search, bidi_cache_iterator_state)
11487 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11488 (bidi_level_of_next_char, bidi_move_to_visually_next):
11489 Support character positions inside a run of characters covered by a
11491 (bidi_paragraph_init, bidi_resolve_explicit_1)
11492 (bidi_level_of_next_char): Call bidi_fetch_char and
11493 bidi_fetch_char_advance instead of FETCH_CHAR and

11496 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11498 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11499 instead of using explicit *_CHAR codes.
11500 (bidi_resolve_explicit, bidi_resolve_weak):
11501 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11502 bidirectional text is supported only in multibyte buffers.
11503 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11504 it to initialize the frame_window_p member of struct bidi_it.

11509 (bidi_level_of_next_char): Don't try to lookup the cache for the
11510 next/previous character if nothing is cached there yet, or if we
11511 were just reseat()'ed to a new position.
11513 * xdisp.c (set_cursor_from_row): Set start and stop points
11514 according to the row's direction when priming the loop that looks
11515 for the glyph on which to display cursor.
11516 (single_display_spec_intangible_p): Function deleted.
11517 (display_prop_intangible_p): Reimplement to call
11518 handle_display_spec instead of single_display_spec_intangible_p.
11519 Accept 3 additional arguments needed by handle_display_spec.
11520 This fixes incorrect cursor motion across display property with complex
11521 values: lists, `(when COND...)' forms, etc.

11523 lists with the argument STRING its top-level element.
11524 (display_prop_string_p): Fix the condition for processing a
11525 property that is a list to be consistent with handle_display_spec.

11527 last portion of handle_display_prop.
11528 (compute_display_string_pos): Accept additional argument
11529 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11530 value of a `display' property is a "replacing spec".
11531 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11532 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11533 the display property, but just return a value indicating whether
11534 the display property will replace the characters it covers.
11535 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11536 frame_window_p members of struct bidi_it.
11537 (compute_display_string_pos, compute_display_string_end):
11539 (push_it): Accept second argument POSITION, where pop_it should
11540 jump to continue iteration.
11541 (reseat_1): Initialize bidi_it.disp_pos.
11543 * keyboard.c (adjust_point_for_property): Adjust the call to
11544 display_prop_intangible_p to its new signature.
11546 * dispextern.h (struct bidi_it): New member frame_window_p.
11547 (bidi_init_it): Update prototypes.
11548 (display_prop_intangible_p): Update prototype.
11549 (compute_display_string_pos, compute_display_string_end):

11554 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11556 Malloc failure behavior now depends on size of allocation.
11557 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11558 * lisp.h: Change signatures accordingly.
11559 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11560 All callers changed. (Bug#8762)
11562 * gnutls.c: Use Emacs's memory allocators.
11563 Without this change, the gnutls library would invoke malloc etc.
11564 directly, which causes problems on non-SYNC_INPUT hosts, and which
11565 runs afoul of improving memory_full behavior. (Bug#8761)
11566 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11567 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11568 xfree instead of the default malloc, realloc, free.
11569 (Fgnutls_boot): No need to check for memory allocation failure,
11570 since xmalloc does that for us.
11572 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11573 * category.c (hash_get_category_set):
11574 * ccl.c (ccl_driver):

11586 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11587 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11588 * image.c (make_image, search_image_cache, lookup_image)
11589 (xpm_put_color_table_h):
11590 * lisp.h (struct Lisp_Hash_Table):
11591 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11592 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11593 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11594 * alloc.c (allocate_vectorlike):
11595 Check for overflow in vector size calculations.
11596 * ccl.c (ccl_driver):
11597 Check for overflow when converting EMACS_INT to int.
11598 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11599 need to be updated by these changes.
11600 * fns.c (make_hash_table, maybe_resize_hash_table):
11601 Check for integer overflow with large hash tables.
11602 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11603 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11604 (SXHASH_REDUCE): New macro.
11605 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11606 Use it instead of discarding useful hash info with large hash values.
11607 (sxhash_float): New function.
11608 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11609 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11610 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11611 Rewrite to use FIXNUM_BITS, as this simplifies things.
11612 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11613 Adjust signatures to match updated version of code.
11614 (consing_since_gc): Now EMACS_INT, since a single hash table can
11615 use more than INT_MAX bytes.
11617 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11619 Make it possible to build with GCC-4.6+ -O2 -flto.
11621 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11623 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11625 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11626 Call minibuffer-inactive-mode.
11628 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11630 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11631 Update dependencies.
11633 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11635 * data.c (init_data): Remove code for UTS, this system is not
11638 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11640 Don't force ./temacs to start in terminal mode.
11642 * frame.c (make_initial_frame): Initialize faces in all cases, not
11643 only when CANNOT_DUMP is defined.
11644 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11646 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11648 * dispnew.c (add_window_display_history): Use const for the string
11649 pointer. Remove declaration, not needed.
11651 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11653 Use 'inline', not 'INLINE'.
11654 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11655 * alloc.c, fontset.c (INLINE): Remove.
11656 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11657 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11658 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11659 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11660 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11662 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11664 Make it possible to run ./temacs.
11666 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11667 syms_of_callproc does the same thing. Remove test for
11668 "initialized", do it in the caller.
11669 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11671 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11673 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.

11683 (CCL_CODE_MIN): New macro.
11685 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11687 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11689 * eval.c (Qdebug): Now static.
11690 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11691 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11692 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11694 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11696 * image.c: Various fixes to ImageMagick code comments.
11697 (Fimagemagick_types): Doc fix.
11699 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11701 Minor fixes prompted by GCC 4.6.0 warnings.
11703 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11705 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11706 (x_clipboard_manager_save_all): Move extern decl to ...
11707 * xterm.h: ... here, so that it can be checked for consistency.
11709 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11711 * xselect.c (x_clipboard_manager_save_frame)
11712 (x_clipboard_manager_save_all): New functions.

11716 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11718 * xterm.h: Update prototype.
11720 2011-05-28 William Xu <william.xwl@gmail.com>
11722 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11723 exiting (Bug#8239).
11725 2011-05-28 Jim Meyering <meyering@redhat.com>
11727 Avoid a sign-extension bug in crypto_hash_function.
11728 * fns.c (to_uchar): Define.
11729 (crypto_hash_function): Use it to convert some newly-signed
11730 variables to unsigned, to avoid sign-extension bugs. For example,
11731 without this change, (md5 "truc") would evaluate to
11732 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11733 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11734 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11736 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11738 Integer overflow fixes.
11740 * dbusbind.c: Serial number integer overflow fixes.
11741 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11742 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11743 to hold a serial number that is too large for a fixnum.
11744 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11745 Check for serial numbers out of range. Decode any serial number
11746 that was so large that it became a float. (Bug#8722)
11748 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11749 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11750 Use XFASTINT rather than XUINT when numbers are nonnegative.
11751 (xd_append_arg, Fdbus_method_return_internal):
11752 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11753 arguments, check that Lisp number is nonnegative, rather than
11754 silently wrapping negative numbers around. (Bug#8722)
11755 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11758 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11760 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11762 ccl: Add integer overflow checks.
11763 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11764 (IN_INT_RANGE): New macros.
11765 (ccl_driver): Use them to check for integer overflow when
11766 decoding a CCL program. Many of the new checks are whether XINT (x)
11767 fits in int; it doesn't always, on 64-bit hosts. The new version
11768 doesn't catch all possible integer overflows, but it's an
11769 improvement. (Bug#8719)
11771 * alloc.c (make_event_array): Use XINT, not XUINT.
11772 There's no need for unsigned here.
11774 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11775 This follows up to the 2011-05-06 change that substituted uintptr_t
11776 for EMACS_INT. This case wasn't caught back then.
11778 Rework Fformat to avoid integer overflow issues.
11779 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11780 now (part of C89). Include <verify.h>.
11781 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11782 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11783 (Fformat): Avoid the prepass trying to compute sizes; it was only
11784 approximate and thus did not catch overflow reliably. Instead, walk
11785 through the format just once, formatting and computing sizes as we go,
11786 checking for integer overflow at every step, and allocating a larger
11787 buffer as needed. Keep track separately whether the format is
11788 multibyte. Keep only the most-recently calculated precision, rather
11789 than them all. Record whether each argument has been converted to
11790 string. Use EMACS_INT, not int, for byte and char and arg counts.
11791 Support field widths and precisions larger than INT_MAX. Avoid
11792 sprintf's undefined behavior with conversion specifications such as %#d
11793 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11794 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11795 formatting out-of-range floating point numbers with int
11796 formats. (Bug#8668)
11798 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11800 * data.c: Avoid integer truncation in expressions involving floats.
11801 * data.c: Include <intprops.h>.
11802 (arith_driver): When there's an integer overflow in an expression
11803 involving floating point, convert the integers to floating point
11804 so that the resulting value does not suffer from catastrophic
11805 integer truncation. For example, on a 64-bit host (* 4
11806 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11807 Do not rely on undefined behavior after integer overflow.
11809 merge count_size_as_multibyte, parse_str_to_multibyte
11810 * character.c, character.h (count_size_as_multibyte):
11811 Rename from parse_str_to_multibyte; all uses changed.
11812 Check for integer overflow.
11813 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11814 since it's now a duplicate of the other. This is more of
11815 a character than a buffer op, so better that it's in character.c.
11816 * fns.c, print.c: Adjust to above changes.
11818 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11820 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11822 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11824 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11825 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11826 (x_clipboard_manager_save): Now static.
11827 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11829 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11830 (crypto_hash_function): Now static.
11831 Fix pointer signedness problems. Avoid unnecessary initializations.
11833 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11835 * termhooks.h (Vselection_alist): Make it terminal-local.
11837 * terminal.c (create_terminal): Initialize it.
11839 * xselect.c: Support for clipboard managers.
11840 (Vselection_alist): Move to termhooks.h as terminal-local var.
11841 (LOCAL_SELECTION): New macro.
11842 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11843 (symbol_to_x_atom): Remove gratuitous arg.
11844 (x_handle_selection_request, lisp_data_to_selection_data)
11845 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11846 (x_own_selection, x_get_local_selection, x_convert_selection):
11847 New arg, specifying work frame. Use terminal-local Vselection_alist.
11848 (some_frame_on_display): Delete unused function.
11849 (Fx_own_selection_internal, Fx_get_selection_internal)
11850 (Fx_disown_selection_internal, Fx_selection_owner_p)
11851 (Fx_selection_exists_p): New optional frame arg.
11852 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11853 (x_handle_selection_clear): Don't treat other terminals with the
11854 same keyboard specially. Use the terminal-local Vselection_alist.
11855 (x_clear_frame_selections): Use Frun_hook_with_args.
11857 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11859 * xterm.h: Add support for those atoms.
11861 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11863 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11864 (converted_selections, conversion_fail_tag): New global variables.
11865 (x_selection_request_lisp_error): Free the above.
11866 (x_get_local_selection): Remove unnecessary code.
11867 (x_reply_selection_request): Args changed; handle arbitrary array
11868 of converted selections stored in converted_selections.
11869 Separate the XChangeProperty and SelectionNotify steps.
11870 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11871 (x_convert_selection): New function.
11872 (x_handle_selection_event): Simplify.
11873 (x_get_foreign_selection): Don't ignore incoming requests while
11874 waiting for an answer; this will fail when we implement
11875 SAVE_TARGETS, and seems unnecessary anyway.
11876 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11877 (Vx_sent_selection_functions): Doc fix.
11879 2011-05-26 Leo Liu <sdl.web@gmail.com>
11881 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11883 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11885 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11887 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11888 for fringe update if it has periodic bitmap.
11889 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11890 and fringe_bitmap_periodic_p.
11892 * fringe.c (get_fringe_bitmap_data): New function.
11893 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11894 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11895 row. Mark glyph row for fringe update if periodicity changed.
11897 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11898 for fringe update unless it has periodic bitmap.
11900 2011-05-25 Kenichi Handa <handa@m17n.org>
11902 * xdisp.c (get_next_display_element): Set correct it->face_id for
11903 a static composition.
11905 2011-05-24 Leo Liu <sdl.web@gmail.com>
11908 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11910 * fns.c (crypto_hash_function, Fsha1): New function.
11911 (Fmd5): Use crypto_hash_function.
11912 (syms_of_fns): Add Ssha1.
11914 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11916 * gnutls.c: Remove unused macros.
11917 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11918 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11919 Remove macros that are defined and never used.
11920 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11922 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11924 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11925 (Fx_get_selection_internal): Minor cleanup.
11926 (Fx_own_selection_internal): Rename arguments for consistency with
11929 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11931 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11933 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11935 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11937 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11939 * dispnew.c (scrolling_window): Don't exclude the case that the
11940 last enabled row in the desired matrix touches the bottom boundary.
11942 2011-05-21 Glenn Morris <rgm@gnu.org>
11944 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11945 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11946 and add some more files.
11948 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11950 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11951 report_file_error introduced by the change from 2011-05-07.
11953 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11955 * systime.h (Time): Define only if emacs is defined.
11956 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11957 where the include path doesn't have X11/X.h by default. See
11958 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11960 2011-05-20 Kenichi Handa <handa@m17n.org>
11962 * composite.c (find_automatic_composition): Fix previous change.
11964 2011-05-20 Glenn Morris <rgm@gnu.org>
11966 * lisp.mk: New file, split from Makefile.in.
11967 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11968 (shortlisp): Remove.
11969 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11971 2011-05-19 Glenn Morris <rgm@gnu.org>
11973 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11974 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11975 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11976 (lisp): Set the order to that of loadup.el.
11977 (shortlisp): Make it a copy of $lisp.
11978 (SOME_MACHINE_LISP): Remove.
11979 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11980 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11982 2011-05-18 Kenichi Handa <handa@m17n.org>
11984 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11985 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11986 (find_automatic_composition): Mostly rewrite for efficiency.
11988 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11990 * makefile.w32-in: Update dependencies.
11992 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11994 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11995 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11997 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11999 Fix some integer overflow issues, such as string length overflow.
12001 * insdel.c (count_size_as_multibyte): Check for string overflow.
12003 * character.c (lisp_string_width): Check for string overflow.
12004 Use EMACS_INT, not int, for string indexes and lengths; in
12005 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12006 the resulting string length overflows an EMACS_INT; instead,
12007 report a string overflow if no precision given. When checking for
12008 precision exhaustion, use a check that cannot possibly have
12009 integer overflow. (Bug#8675)
12010 * character.h (lisp_string_width): Adjust to new signature.
12012 * alloc.c (string_overflow): New function.
12013 (Fmake_string): Use it. This doesn't change behavior, but saves
12014 a few bytes and will simplify future changes.
12015 * character.c (string_escape_byte8): Likewise.
12016 * lisp.h (string_overflow): New decl.
12018 Fixups, following up to the user-interface timestamp change.
12019 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12020 for UI timestamps, instead of unsigned long.
12021 * msdos.c (mouse_get_pos): Likewise.
12022 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12023 * w32gui.h (Time): Define by including "systime.h" rather than by
12024 declaring it ourselves. (Bug#8664)
12026 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12027 * image.c (clear_image_cache): Likewise.
12029 * term.c (term_mouse_position): Don't assume time_t wraparound.
12031 Be more systematic about user-interface timestamps.
12032 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12033 and sometimes 'EMACS_UINT', to represent these timestamps.
12034 This change causes it to use 'Time' uniformly, as that's what X uses.
12035 This makes the code easier to follow, and makes it easier to catch
12036 integer overflow bugs such as Bug#8664.
12037 * frame.c (Fmouse_position, Fmouse_pixel_position):
12038 Use Time, not unsigned long, for user-interface timestamps.
12039 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12040 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12041 * keyboard.h (last_event_timestamp): Likewise.
12042 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12043 * menu.h (xmenu_show): Likewise.
12044 * term.c (term_mouse_position): Likewise.
12045 * termhooks.h (struct input_event.timestamp): Likewise.
12046 (struct terminal.mouse_position_hook): Likewise.
12047 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12048 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12049 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12050 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12051 what it was before.
12052 * menu.h, termhooks.h: Include "systime.h", for Time.
12054 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12055 Don't assume that the difference between two unsigned long values
12056 can fit into an integer. At this point, we know button_down_time
12057 <= event->timestamp, so the difference must be nonnegative, so
12058 there's no need to cast the result if double-click-time is
12059 nonnegative, as it should be; check that it's nonnegative, just in
12060 case. This bug is triggered when events are more than 2**31 ms
12061 apart (about 25 days). (Bug#8664)
12063 * xselect.c (last_event_timestamp): Remove duplicate decl.
12064 (x_own_selection): Remove needless cast to unsigned long.
12066 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12067 that always fit in int. Use a sentinel instead of a counter, to
12068 avoid a temp and to allay GCC's concerns about possible int overflow.
12069 * frame.h (struct frame): Use int for menu_bar_items_used
12070 instead of EMACS_INT, since it always fits in int.
12072 * menu.c (grow_menu_items): Check for int overflow.
12074 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12076 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12077 Before, the code was not consistent. These values cannot exceed
12078 2**31 - 1 so there's no need to make them unsigned.
12079 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12080 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12081 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12083 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12085 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12086 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12087 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12088 presumably because the widths might not match.
12090 * window.c (size_window): Avoid needless test at loop start.
12092 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12094 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12096 2011-05-12 Drew Adams <drew.adams@oracle.com>
12098 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12100 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12102 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12103 `width' to `bar_area_x' and `bar_area_width', respectively.
12104 (x_scroll_run): Take account of fringe background extension.
12106 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12107 Rename local vars `left' and `width' to `bar_area_x' and
12108 `bar_area_width', respectively.
12109 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12110 background extension.
12112 2011-05-10 Jim Meyering <meyering@redhat.com>
12114 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12116 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12118 * image.c (Finit_image_library): Return t for built-in image types,
12119 like pbm and xbm. (Bug#8640)
12121 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12123 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12125 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12127 * w32console.c (Fset_screen_color): Doc fix.
12128 (Fget_screen_color): New function.
12129 (syms_of_ntterm): Defsubr it.
12131 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12132 unlink the temporary file if Fcall_process didn't create it in the
12134 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12135 child process will be redirected to a file specified with `:file'.
12136 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12137 cue to call_process_cleanup not to close that handle.
12139 2011-05-07 Ben Key <bkey76@gmail.com>
12141 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12142 one of two shell specific rules, either bootstrap-temacs-CMD or
12143 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12144 to the previous implementation of the bootstrap-temacs rule.
12145 The bootstrap-temacs-CMD rule is similar to the previous
12146 implementation of the bootstrap-temacs rule except that it
12147 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12150 These changes, along with some changes to nt/configure.bat,
12151 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12152 earlier fix to add support for --cflags and --ldflags options
12153 that include quotes so that it works whether make uses cmd or
12156 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12158 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12159 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12161 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12162 a string. Handle both cases.
12163 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12164 (Fdbus_register_method): Use Qinvalid_function.
12166 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12168 * makefile.w32-in: Update dependencies.
12169 (LISP_H): Add inttypes.h and stdin.h.
12170 (PROCESS_H): Add unistd.h.
12172 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12174 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12175 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12177 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12179 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12181 * term.c (vfatal): Remove stray call to va_end.
12182 It's not needed and the C Standard doesn't allow it here anyway.
12184 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12185 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12187 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12190 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12192 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12194 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12196 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12198 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12200 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12201 * charset.c (Fdefine_charset_internal): Don't initialize
12202 charset.code_space[15]. The value was garbage, on hosts with
12203 32-bit int (Bug#8600).
12205 * lread.c (read_integer): Be more consistent with string-to-number.
12206 Use string_to_number to do the actual conversion; this avoids
12207 rounding errors and fixes some other screwups. Without this fix,
12208 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12209 (digit_to_number): Move earlier, for benefit of read_integer.
12210 Return -1 if the digit is out of range for the base, -2 if it is
12211 not a digit in any supported base. (Bug#8602)
12213 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12215 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12216 to match comment at start of function. This also removes a
12217 GCC warning about overflow in a 32+64-bit port.
12219 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12221 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12222 Reported by Stefan Monnier in
12223 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12224 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12225 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12227 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12228 (EMACS_UINTPTR): Likewise, with uintptr_t.
12230 * lisp.h: Prefer 64-bit EMACS_INT if available.
12231 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12232 on 32-bit hosts that have 64-bit int, so that they can access
12234 However, temporarily disable this change unless the temporary
12235 symbol WIDE_EMACS_INT is defined.
12237 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12239 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12240 This removes an assumption that EMACS_INT and long are the same
12241 width as pointers. The assumption is true for Emacs porting targets
12242 now, but we want to make other targets possible.
12243 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12244 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12245 In the rest of the code, change types of integers that hold casted
12246 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12247 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12248 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12249 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12250 No need to cast type when ORing.
12251 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12252 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12253 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12254 assume EMACS_INT is the same width as char *.
12255 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12256 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12257 Remove no-longer-needed casts.
12258 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12259 (xg_tool_bar_help_callback, xg_make_tool_item):
12260 Use EMACS_INTPTR to hold an integer
12261 that will be cast to void *; this can avoid a GCC warning
12262 if EMACS_INT is not the same width as void *.
12263 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12264 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12265 (current_message_1, set_message_1):
12266 Use a local to convert to proper width without a cast.
12267 * xmenu.c (dialog_selection_callback): Likewise.
12269 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12270 Also, don't assume VALBITS / RAND_BITS is less than 5,
12271 and don't rely on undefined behavior when shifting a 1 left into
12273 * lisp.h (get_random): Change signature to match.
12275 * lread.c (hash_string): Use size_t, not int, for hash computation.
12276 Normally we prefer signed values; but hashing is special, because
12277 it's better to use unsigned division on hash table sizes so that
12278 the remainder is nonnegative. Also, size_t is the natural width
12279 for hashing into memory. The previous code used 'int', which doesn't
12280 retain enough info to hash well into very large tables.
12281 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12283 * dbusbind.c: Don't possibly lose pointer info when converting.
12284 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12285 Use XPNTR rather than XHASH, so that the high-order bits of
12286 the pointer aren't lost when converting through void *.
12288 * eval.c (Fautoload): Don't double-shift a pointer.
12290 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12292 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12294 * gnutls.c (DEF_GNUTLS_FN):
12295 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12297 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12299 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12302 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12304 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12305 New version that can reserve upto 2GB of heap space.
12307 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12309 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12311 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12313 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12314 `gnutls_certificate_set_x509_key_file'.
12316 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12318 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12319 Update dependencies.
12321 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12323 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12324 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12325 Remove unused parameter `fildes'.
12326 * process.c (read_process_output, send_process): Don't pass it.
12328 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12330 Fix previous change: the library cache is defined in w32.c.
12331 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12332 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12334 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12336 Implement dynamic loading of GnuTLS on Windows.
12338 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12339 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12340 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12343 * gnutls.c (Qgnutls_dll): Define.
12344 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.

12350 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12351 (emacs_gnutls_write, emacs_gnutls_read)
12352 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12353 (Fgnutls_available_p): New function.
12354 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

12364 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12366 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12367 (w32_delayed_load): Move from image.c. When loading a library, record
12368 its filename in the :loaded-from property of the library id.
12369 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12370 Initialize and staticpro them.
12371 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12373 * process.c: Include lisp.h before w32.h, not after.
12374 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12375 instead of gnutls_record_check_pending.
12377 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12379 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12381 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12382 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12385 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12387 * xterm.c (x_set_frame_alpha): Do not set property on anything
12388 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12390 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12392 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12394 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12396 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12397 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12411 (wait_for_termination, interruptible_wait_for_termination):
12412 Move after wait_for_termination_1.
12414 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12416 * sysdep.c (interruptible_wait_for_termination): New function
12417 which is like wait_for_termination, but allows keyboard
12420 * callproc.c (Fcall_process): Add (:file "file") as an option for
12422 (Fcall_process_region): Ditto.
12424 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12426 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12427 rather than `XVECTOR (FOO)->size'.
12429 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12430 inttypes.h, as a gnulib replacement is used if it not available in
12433 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12435 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12436 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12437 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12439 * coding.c (coding_alloc_by_realloc): Error out if destination
12440 will grow beyond MOST_POSITIVE_FIXNUM.
12441 (decode_coding_emacs_mule): Abort if there isn't enough place in
12442 charbuf for the composition carryover bytes. Reserve an extra
12443 space for up to 2 characters produced in a loop.
12444 (decode_coding_iso_2022): Abort if there isn't enough place in
12445 charbuf for the composition carryover bytes.
12447 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12449 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12450 aborting when %lld or %lll format is passed.
12451 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12452 %llo or %llx format is passed. (Bug#8545)
12454 * window.c (window_scroll_line_based): Use a marker instead of
12455 simple variables to record original value of point. (Bug#7952)
12457 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12458 produced by %s or %c overflows available buffer space. (Bug#8545)
12460 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12462 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12463 (SIZE_MAX): Move defn after all includes, as they might #define it.
12465 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12467 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12469 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12471 * keyboard.c (Qdelayed_warnings_hook): Define.
12472 (command_loop_1): Run `delayed-warnings-hook'
12473 if Vdelayed_warnings_list is non-nil.
12474 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12475 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12477 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12479 * doprnt.c (doprnt): Don't return value smaller than the buffer
12480 size if the message was truncated. (Bug#8545).
12482 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12484 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12485 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12487 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12489 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12491 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12493 * makefile.w32-in: Update dependencies.
12495 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12497 Improve `doprnt' and its usage. (Bug#8545)
12498 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12499 `format_end'. Remove support for %l as a conversion specifier.
12500 Don't use xrealloc. Improve diagnostics when the %l size modifier
12501 is used. Update the commentary.
12503 * eval.c (verror): Simplify calculation of size_t.
12505 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12508 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12510 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12513 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12515 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12516 This makes this file independent of the recent pseudovector change.
12518 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12520 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12522 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12523 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12524 Remove unused local.
12525 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12527 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12528 GCC 4.6.0 optimizes based on type-based alias analysis.
12529 For example, if b is of type struct buffer * and v of type struct
12530 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12531 != &v->size, and therefore "v->size = 1; b->size = 2; return
12532 v->size;" must therefore return 1. This assumption is incorrect
12533 for Emacs, since it type-puns struct Lisp_Vector * with many other
12534 types. To fix this problem, this patch adds a new type struct
12535 vectorlike_header that documents the constraints on layout of vectors
12536 and pseudovectors, and helps optimizing compilers not get fooled
12537 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12538 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12539 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12541 (XSETPVECTYPE): Rewrite in terms of new macro.
12542 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12543 This is a bit clearer, and further avoids the possibility of
12544 undesirable aliasing.
12545 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12546 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12547 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12548 since Lisp_Subr is a special case (no "next" field).
12549 (ASIZE): Now uses header.size rather than size.
12550 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12551 to avoid the hassle of writing XVECTOR (foo)->header.size.
12552 (struct vectorlike_header): New type.
12553 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12554 object, to help avoid aliasing.
12555 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12556 (SUBRP): Likewise, since Lisp_Subr is a special case.
12557 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12558 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12559 (struct Lisp_Hash_Table): Combine first two members into a single
12560 struct vectorlike_header member. All uses of "size" and "next" members
12561 changed to be "header.size" and "header.next".
12562 * buffer.h (struct buffer): Likewise.
12563 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12564 * frame.h (struct frame): Likewise.
12565 * process.h (struct Lisp_Process): Likewise.
12566 * termhooks.h (struct terminal): Likewise.
12567 * window.c (struct save_window_data, struct saved_window): Likewise.
12568 * window.h (struct window): Likewise.
12569 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12570 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12571 * buffer.c (init_buffer_once): Likewise.
12572 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12574 * process.c (Fformat_network_address): Use local var for size,
12577 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12579 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12580 * data.c (atof): Remove decl; no longer used or needed.
12581 (digit_to_number): Move to lread.c.
12582 (Fstring_to_number): Use new string_to_number function, to be
12583 consistent with how the Lisp reader treats infinities and NaNs.
12584 Do not assume that floating-point numbers represent EMACS_INT
12585 without losing information; this is not true on most 64-bit hosts.
12586 Avoid double-rounding errors, by insisting on integers when
12587 parsing non-base-10 numbers, as the documentation specifies.
12588 * lisp.h (string_to_number): New decl, replacing ...
12589 (isfloat_string): Remove.
12590 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12591 (read1): Do not accept +. and -. as integers; this
12592 appears to have been a coding error. Similarly, do not accept
12593 strings like +-1e0 as floating point numbers. Do not report
12594 overflow for integer overflows unless the base is not 10 which
12595 means we have no simple and reliable way to continue.
12596 Break out the floating-point parsing into a new
12597 function string_to_number, so that Fstring_to_number parses
12598 floating point numbers consistently with the Lisp reader.
12599 (digit_to_number): Move here from data.c. Make it static inline.
12600 (E_CHAR, EXP_INT): Remove, replacing with ...
12601 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12602 (string_to_number): New function, replacing isfloat_string.
12603 This function checks for valid syntax and produces the resulting
12604 Lisp float number too. Rework it so that string-to-number
12605 no longer mishandles examples like "1.0e+". Use strtoumax,
12606 so that overflow for non-base-10 numbers is reported only when
12607 there's no portable and simple way to convert to floating point.
12609 * textprop.c (set_text_properties_1): Rewrite for clarity,
12610 and to avoid GCC warning about integer overflow.
12612 * intervals.h (struct interval): Use EMACS_INT for members
12613 where EMACS_UINT might cause problems. See
12614 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12615 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12616 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12618 (offset_intervals): Tell GCC not to worry about length overflow
12619 when negating a negative length.
12621 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12622 (overrun_check_free): Likewise.
12624 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12625 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12628 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12629 (gnutls_make_error): Rename local to avoid shadowing.
12630 (gnutls_emacs_global_deinit): ifdef out; not used.
12631 (Fgnutls_boot): Use const for pointer to readonly storage.
12632 Comment out unused local. Fix pointer signedness problems.
12634 * lread.c (openp): Don't stuff size_t into an 'int'.
12635 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12636 about possible signed overflow.
12638 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12639 (GDK_KEY_g): Don't define if already defined.
12640 (xg_prepare_tooltip): Avoid pointer signedness problem.
12641 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12643 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12644 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12646 * xfns.c (Fx_window_property): Simplify a bit,
12647 to make a bit faster and to avoid GCC 4.6.0 warning.
12648 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12650 * fns.c (internal_equal): Don't assume size_t fits in int.
12652 * alloc.c (compact_small_strings): Tighten assertion a little.
12654 Replace pEd with more-general pI, and fix some printf arg casts.
12655 * lisp.h (pI): New macro, generalizing old pEd macro to other
12656 conversion specifiers. For example, use "...%"pI"d..." rather
12657 than "...%"pEd"...".
12658 (pEd): Remove. All uses replaced with similar uses of pI.
12659 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12660 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12661 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12662 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12663 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12664 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12665 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12667 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12668 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12669 * print.c (safe_debug_print, print_object): Likewise.
12670 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12672 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12673 avoiding the 0 flag, which is not portable.
12674 * process.c (Fmake_network_process): Use pI to avoid cast.
12675 * region-cache.c (pp_cache): Likewise.
12676 * xdisp.c (decode_mode_spec): Likewise.
12677 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12678 behavior on 64-bit hosts with printf arg.
12679 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12680 (x_stop_queuing_selection_requests): Likewise.
12681 (x_get_window_property): Don't truncate byte count to an 'int'
12684 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12685 here, since it parses constructs like leading '-' and spaces,
12686 which are not wanted; and it overflows with large numbers.
12687 Instead, simply match F[0-9]+, which is what is wanted anyway.
12689 * alloc.c: Remove unportable assumptions about struct layout.
12690 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12691 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12692 (allocate_vectorlike, make_pure_vector): Use the new macros,
12693 plus offsetof, to remove unportable assumptions about struct layout.
12694 These assumptions hold on all porting targets that I know of, but
12695 they are not guaranteed, they're easy to remove, and removing them
12696 makes further changes easier.
12698 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12699 This doesn't fix a bug but makes the code clearer.
12700 (string_overrun_cookie): Now const. Use initializers that
12701 don't formally overflow signed char, to avoid warnings.
12702 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12703 can cause Emacs to crash when string overrun checking is enabled.
12704 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12705 multiple of sizeof (EMACS_INT); it need not be, if
12706 alignof(EMACS_INT) < sizeof (EMACS_INT).
12707 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12709 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12736 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12738 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12739 "cast to pointer from integer of different size".
12741 Improve doprnt and its use in verror. (Bug#8545)
12742 * doprnt.c (doprnt): Document the set of format control sequences
12743 supported by the function. Use SAFE_ALLOCA instead of always
12746 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12747 is one byte too soon. Don't use xrealloc; instead xfree and
12750 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12752 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

12756 gnutls_global_initialized. Added internals for the
12757 :verify-hostname-error, :verify-error, and :verify-flags
12758 parameters of `gnutls-boot' and documented those parameters in the
12759 docstring. Start callback support.
12760 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12761 unless a fatal error occurred. Call gnutls_alert_send_appropriate

12865 codepoint of an invalid character, to avoid displaying a bogus
12868 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12869 `error', not SYMBOL_NAME itself.

12874 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12875 to `error' in error message about FINAL_CHAR argument. Make sure
12876 FINAL_CHAR is a character, and use %c when it is passed as
12877 argument to `error'.
12879 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12881 * s/ms-w32.h (localtime): Redirect to sys_localtime.
12883 * w32.c: Include <time.h>.

12947 * dispextern.h (struct redisplay_interface): Rename param
12948 to avoid shadowing.
12949 * termhooks.h (struct terminal): Likewise.
12950 * xterm.c (xembed_send_message): Likewise.
12952 * insdel.c (make_gap_smaller): Define only if
12953 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.

13051 (group_in_compile_stack, re_search, re_search_2, regex_compile)
13052 (re_compile_pattern, re_exec): Declare arguments and local
13053 variables `size_t' and `ssize_t' and return values `regoff_t', as

13066 * nsfont.m: Fixed bugs in ns_get_family and
13067 ns_descriptor_to_entity that were caused by using free to
13068 deallocate memory blocks that were allocated by xmalloc (via
13069 xstrdup). This caused Emacs to crash when compiled with
13070 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13071 --enable-checking=xmallocoverrun). xfree is now used to
13072 deallocate these memory blocks.

13086 (emacs_read, emacs_write): Remove check for negative size, as the
13087 Emacs source code has been audited now.
13088 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
13089 (emacs_read, emacs_write): Use it.
13090 * process.c (send_process): Adjust to the new signatures of
13091 emacs_write and emacs_gnutls_write. Do not attempt to store
13092 a byte offset into an 'int'; it might overflow.
13093 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

13516 * intervals.h (Fprevious_property_change):
13517 (Fremove_list_of_text_properties): Remove decls.
13518 * keyboard.c (Fthis_command_keys): Remove decl.
13519 (Fcommand_execute): New forward static decl.
13520 * keymap.c (Flookup_key): New forward static decl.
13521 (Fcopy_keymap): Now static.
13522 * keymap.h (Flookup_key): Remove decl.
13523 * process.c (Fget_process): New forward static decl.
13524 (Fprocess_datagram_address): Mark as internal.
13525 * syntax.c (Fsyntax_table_p): New forward static decl.
13526 (skip_chars): Remove duplicate decl.

13540 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13542 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13543 when at ZV. (Bug#8487)
13545 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13547 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13549 * keyboard.c (parse_tool_bar_item): Likewise.
13550 * sound.c (sound_cleanup, alsa_close): Likewise.
13551 * termcap.c (tgetent): Likewise.
13552 * xfns.c (x_default_font_parameter): Likewise.
13553 * xsettings.c (read_and_apply_settings): Likewise.
13555 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13556 (overrun_check_free): Protoize.
13558 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13560 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13561 since callers should never pass a negative size.
13562 Change the signature to match that of plain 'read' and 'write'; see
13563 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13564 * lisp.h: Update prototypes of emacs_write and emacs_read.
13566 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13568 * xdisp.c (redisplay_window): Don't try to determine the character
13569 position of the scroll margin if the window start point w->startp
13570 is outside the buffer's accessible region. (Bug#8468)
13572 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13574 Fix write-region and its subroutines for buffers > 2GB.
13575 * fileio.c (a_write, e_write): Modify declaration of arguments and
13576 local variables to support buffers larger than 2GB.
13577 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13579 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13580 argument, local variables, and return value.
13582 * lisp.h: Update prototypes of emacs_write and emacs_read.
13584 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13586 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13588 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13590 Fix more problems found by GCC 4.6.0's static checks.
13592 * xdisp.c (vmessage): Use a better test for character truncation.
13594 * charset.c (load_charset_map): <, not <=, for optimization,
13595 and to avoid potential problems with integer overflow.
13596 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13597 * casetab.c (set_identity, shuffle): Likewise.
13598 * editfns.c (Fformat): Likewise.
13599 * syntax.c (skip_chars): Likewise.
13601 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13602 This also lets GCC 4.6.0 generate slightly better loop code.
13604 * callint.c (Fcall_interactively): <, not <=, for optimization.
13605 (Fcall_interactively): Count the number of arguments produced,
13606 not the number of arguments given. This is simpler and lets GCC
13607 4.6.0 generate slightly better code.
13609 * ftfont.c: Distingish more carefully between FcChar8 and char.
13610 The previous code passed unsigned char * to a functions like
13611 strlen and xstrcasecmp that expect char *, which does not
13612 conform to the C standard.
13613 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13614 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13615 char * when the C standard requires it.
13617 * keyboard.c (read_char): Remove unused var.
13619 * eval.c: Port to Windows vsnprintf (Bug#8435).
13620 Include <limits.h>.
13621 (SIZE_MAX): Define if the headers do not.
13622 (verror): Do not give up if vsnprintf returns a negative count.
13623 Instead, grow the buffer. This ports to Windows vsnprintf, which
13624 does not conform to C99. Problem reported by Eli Zaretskii.
13625 Also, simplify the allocation scheme, by avoiding the need for
13626 calling realloc, and removing the ALLOCATED variable.
13628 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13630 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13631 But keep the doprint source code for now, as we might revamp it
13632 and use it again (Bug#8435).
13633 * lisp.h (doprnt): Remove.
13634 * Makefile.in (base_obj): Remove doprnt.o.
13635 * deps.mk (doprnt.o): Remove.
13637 error: Print 32- and 64-bit integers portably (Bug#8435).
13638 Without this change, on typical 64-bit hosts error ("...%d...", N)
13639 was used to print both 32- and 64-bit integers N, which relied on
13640 undefined behavior.
13641 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13642 * lisp.h (error, verror): Mark as printf-like functions.
13643 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13644 Report overflow in size calculations when allocating printf buffer.
13645 Do not truncate output string at its first null byte.
13646 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13647 Truncate the output at a character boundary, since vsnprintf does not
13649 * charset.c (check_iso_charset_parameter): Convert internal
13650 character to string before calling 'error', since %c now has the
13652 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13653 overflow when computing char to be passed to 'error'. Do not
13654 pass Lisp_Object to 'error'; pass the integer instead.
13655 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13656 formatted with plain %d.
13658 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13660 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13662 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13664 * xterm.c (x_catch_errors): Remove duplicate declaration.
13666 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13668 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13670 2011-04-10 Jim Meyering <meyering@redhat.com>
13672 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13673 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13674 return ssize_t not "int", and use size_t as the buffer length.
13675 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13676 * gnutls.h: Update declarations.
13677 * process.c (read_process_output): Use ssize_t, to match.
13678 (send_process): Likewise.
13680 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13682 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13684 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13686 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13687 Use unsigned char, to match FcChar8 type definition.
13689 * xterm.c (handle_one_xevent):
13690 * xmenu.c (create_and_show_popup_menu):
13691 * xselect.c (x_decline_selection_request)
13692 (x_reply_selection_request): Avoid type-punned deref of X events.
13694 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13696 Fix some uses of `int' instead of EMACS_INT.
13697 * search.c (string_match_1, fast_string_match)
13698 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13699 (scan_buffer, find_next_newline_no_quit)
13700 (find_before_next_newline, search_command, Freplace_match)
13701 (Fmatch_data): Make some `int' variables be EMACS_INT.
13703 * xdisp.c (display_count_lines): 3rd argument and return value now
13704 EMACS_INT. All callers changed.
13705 (pint2hrstr): Last argument is now EMACS_INT.
13707 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13708 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13709 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13710 (decode_coding_utf_16, decode_coding_emacs_mule)
13711 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13712 (decode_coding_ccl, decode_coding_charset)
13713 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13714 (decode_coding_iso_2022, decode_coding_emacs_mule)
13715 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13716 <char_offset, last_offset>: Declare EMACS_INT.
13717 (encode_coding_utf_8, encode_coding_utf_16)
13718 (encode_coding_emacs_mule, encode_invocation_designation)
13719 (encode_designation_at_bol, encode_coding_iso_2022)
13720 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13721 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13723 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13724 (encode_invocation_designation): Last argument P_NCHARS is now
13726 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13727 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13729 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13732 * ccl.c (Fccl_execute_on_string): Declare some variables
13735 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13737 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13739 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13741 * process.c (Fformat_network_address): Doc fix.
13743 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13745 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13747 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13749 * keyboard.c (read_char): Call Lisp function help-form-show,
13750 instead of using internal_with_output_to_temp_buffer.
13751 (Qhelp_form_show): New var.
13752 (syms_of_keyboard): Use DEFSYM macro.
13754 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13756 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13758 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13760 * process.c (Flist_processes): Remove to Lisp.
13761 (list_processes_1): Delete.
13763 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13765 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13767 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13769 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13771 Fix more problems found by GCC 4.6.0's static checks.
13773 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13775 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13777 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13779 * xdisp.c (vmessage): Mark as a printf-like function.
13781 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13783 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13785 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13786 printf-like functions.
13787 (tiff_load): Add casts to remove these marks before passing them
13788 to system-supplied API.
13790 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13792 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13793 This avoids several warnings with gcc -Wstrict-overflow.
13794 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13795 directly, rather than having caller test rule sign. This avoids
13796 some unnecessary tests.
13797 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13798 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13799 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13801 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13802 (xfont_open): Avoid unnecessary tests.
13804 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13806 * composite.h, composite.c (composition_gstring_put_cache):
13807 Use EMACS_INT, not int, for length.
13809 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13810 breaking out part of COMPOSITION_DECODE_RULE.
13811 (COMPOSITION_DECODE_RULE): Use it.
13812 * composite.c (get_composition_id): Remove unused local vars,
13813 by using the new macro.
13815 * textprop.c (set_text_properties_1): Change while to do-while,
13816 since the condition is always true at first.
13818 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13819 (interval_deletion_adjustment): Return unsigned value.
13822 * process.c (list_processes_1, create_pty, read_process_output):

13832 (update_syntax_table): Use unsigned instead of int.
13834 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13835 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13836 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13838 * print.c (print_error_message): Avoid int overflow.
13840 * font.c (font_list_entities): Redo for clarity,
13841 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13843 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13844 (font_score): Avoid potential overflow in diff calculation.
13846 * fns.c (substring_both): Remove var that is set but not used.
13847 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13849 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13851 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13852 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13853 can always succeed if overflow has undefined behavior.
13855 * search.c (boyer_moore, wordify): Remove vars set but not used.
13856 (wordify): Omit three unnecessary tests.
13858 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13859 All callers changed. This avoids the need for an unused var.
13861 * casefiddle.c (casify_region): Remove var that is set but not used.
13863 * dired.c (file_name_completion): Remove var that is set but not used.
13865 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13867 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13868 (Finsert_file_contents): Remove unnecessary code checking fd.
13870 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13871 Check for integer overflow on size calculations.
13873 * buffer.c (Fprevious_overlay_change): Remove var that is set
13876 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13877 Remove vars that are set but not used.
13878 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13879 (timer_check_2): Mark vars as initialized.
13881 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13883 * image.c (lookup_image): Remove var that is set but not used.
13884 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13886 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13887 that are set but not used.
13889 * xfns.c (make_invisible_cursor): Don't return garbage
13890 if XCreateBitmapFromData fails (Bug#8410).
13892 * xselect.c (x_get_local_selection, x_handle_property_notify):
13893 Remove vars that are set but not used.
13895 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13896 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13898 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13899 Remove var that is set but not used.

13901 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13902 Check for overflow.
13904 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13905 (map_tty_color) [!defined MSDOS]: Likewise.
13907 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13909 * coding.c: Remove vars that are set but not used.
13910 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13911 All callers changed.
13912 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13913 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13914 (decode_coding_charset): Remove vars that are set but not used.
13916 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13917 that is set but not used.
13919 * print.c (print_object): Remove var that is set but not used.
13921 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13922 The gnulib version avoids calling malloc in the usual case,
13923 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13924 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13925 * filelock.c (current_lock_owner): Likewise.
13926 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13927 * sysdep.c: Include allocator.h, careadlinkat.h.
13928 (emacs_no_realloc_allocator): New static constant.
13929 (emacs_readlink): New function.
13930 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13931 ../lib/careadlinkat.h.
13933 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13935 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13936 first non-nil return value).
13938 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13940 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13941 if not defined (Bug#8403).
13943 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13945 * xdisp.c (display_count_lines): Remove parameter `start',
13946 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13947 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13948 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13950 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13951 and thereabouts. All callers changed.
13952 (get_per_char_metric): Remove parameter `f', unused since
13953 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13955 2011-04-02 Jim Meyering <meyering@redhat.com>
13957 do not dereference NULL upon failed strdup
13958 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13959 (ns_get_family): Likewise.
13961 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13963 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13965 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13967 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13970 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13972 Add lexical binding.
13974 * window.c (Ftemp_output_buffer_show): New fun.
13975 (Fsave_window_excursion):
13976 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13978 * lread.c (lisp_file_lexically_bound_p): New function.
13979 (Fload): Bind Qlexical_binding.
13980 (readevalloop): Remove `evalfun' arg.
13981 Bind Qinternal_interpreter_environment.
13982 (Feval_buffer): Bind Qlexical_binding.
13983 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13985 (syms_of_lread): Declare `lexical-binding'.
13987 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13989 * keyboard.c (eval_dyn): New fun.
13990 (menu_item_eval_property): Use it.
13992 * image.c (parse_image_spec): Use Ffunctionp.
13994 * fns.c (concat, mapcar1): Accept byte-code-functions.
13996 * eval.c (Fsetq): Handle lexical vars.
13997 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13998 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13999 (FletX, Flet): Obey lexical binding.
14000 (Fcommandp): Handle closures.
14001 (Feval): New `lexical' arg.
14002 (eval_sub): New function extracted from Feval. Use it almost
14003 everywhere where Feval was used. Look up vars in lexical env.
14005 (Ffunctionp): Move from subr.el.
14006 (Ffuncall): Handle closures.
14007 (apply_lambda): Remove `eval_flags'.
14008 (funcall_lambda): Handle closures and new byte-code-functions.
14009 (Fspecial_variable_p): New function.
14010 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14011 but without exporting it to Lisp.
14013 * doc.c (Fdocumentation, store_function_docstring):
14014 * data.c (Finteractive_form): Handle closures.
14016 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14019 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14021 (exec_byte_code): New function extracted from Fbyte_code to handle new
14022 calling convention for byte-code-functions. Add new byte-codes.
14024 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14026 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14028 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14030 * xdisp.c (redisplay_internal): Fix prototype.
14032 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14034 * xdisp.c (SCROLL_LIMIT): New macro.
14035 (try_scrolling): Use it when setting scroll_limit.
14036 Limit scrolling to 100 screen lines.
14037 (redisplay_window): Even when falling back on "recentering",
14038 position point in the window according to scroll-conservatively,
14039 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14041 (try_scrolling): When point is above the window, allow searching
14042 as far as scroll_max, or one screenful, to compute vertical
14043 distance from PT to the scroll margin position. This prevents
14044 try_scrolling from unnecessarily failing when
14045 scroll-conservatively is set to a value slightly larger than the
14046 window height. Clean up the case of PT below the margin at bottom
14047 of window: scroll_max can no longer be INT_MAX. When aggressive
14048 scrolling is in use, don't let point enter the opposite scroll
14049 margin as result of the scroll.
14050 (syms_of_xdisp) <scroll-conservatively>: Document the
14051 threshold of 100 lines for never-recentering scrolling.
14053 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14055 * dispextern.h (move_it_by_lines):
14056 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14057 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14058 (message_log_check_duplicate): Remove parameters `prev_bol' and
14059 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14060 (redisplay_internal): Remove parameter `preserve_echo_area',
14061 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14063 * indent.c (Fvertical_motion):
14064 * window.c (window_scroll_pixel_based, Frecenter):
14065 Don't pass `need_y_p' to `move_it_by_lines'.
14067 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14069 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14070 steal a few bits to be more compact.
14071 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14072 Remove unneeded casts.
14074 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14076 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14078 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14079 binding" message (bug#7967).
14081 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14083 Fix more problems found by GCC 4.6.0's static checks.
14085 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14086 Remove unused local var.
14088 * editfns.c (Fmessage_box): Remove unused local var.
14090 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14091 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14092 Omit unused local vars.
14093 * window.c (shrink_windows): Omit unused local var.
14094 * menu.c (digest_single_submenu): Omit unused local var.
14095 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14096 Omit unused local var.
14098 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14099 Don't assume string length fits in int.
14100 (keyremap_step, read_key_sequence): Use size_t for sizes.
14101 (read_key_sequence): Don't check last_real_key_start redundantly.
14103 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14104 instead of alloca (Bug#8344).
14106 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14107 (Fbacktrace_frame): Don't assume nframes fits in int.
14109 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14111 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14114 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14116 * cm.c (calccost): Turn while-do into do-while, for clarity.
14118 * keyboard.c (syms_of_keyboard): Use the same style as later
14119 in this function when indexing through an array. This also
14120 works around GCC bug 48267.
14122 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14124 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14126 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14127 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14129 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14130 This avoids undefined behavior on integer overflow, and is a bit
14131 more convenient anyway since it is compared to a size_t variable.
14133 Variadic C functions now count arguments with size_t, not int.
14134 This avoids an unnecessary limitation on 64-bit machines, which
14135 caused (substring ...) to crash on large vectors (Bug#8344).
14136 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14137 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14138 All variadic functions and their callers changed accordingly.

14142 * eval.c (struct backtrace.nargs, interactive_p)
14143 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14144 (funcall_lambda, mark_backtrace): Likewise.
14145 * fns.c (concat): Likewise.
14146 * frame.c (x_set_frame_parameters): Likewise.
14147 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14148 0 if not found, not -1. All callers changed.
14150 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14151 (stack_copy_size): Now size_t, not int.
14152 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14154 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14156 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14157 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14158 All callers changed.
14160 * lisp.h (multibyte_char_to_unibyte):
14161 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14162 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14163 * character.h (CHAR_TO_BYTE8):
14164 * cmds.c (internal_self_insert):
14165 * editfns.c (general_insert_function):
14166 * keymap.c (push_key_description):
14167 * search.c (Freplace_match):
14168 * xdisp.c (message_dolog, set_message_1): All callers changed.
14170 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14172 * keyboard.c (safe_run_hook_funcall): New function.
14173 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14174 don't set the hook to nil, but remove the offending function instead.
14175 (Qcommand_hook_internal): Remove, unused.
14176 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14177 Vcommand_hook_internal.
14179 * eval.c (enum run_hooks_condition): Remove.
14180 (funcall_nil, funcall_not): New functions.
14181 (run_hook_with_args): Call each function through a `funcall' argument.
14182 Remove `cond' argument, now redundant.
14183 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14184 (Frun_hook_with_args_until_failure): Adjust accordingly.
14185 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14187 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14189 * dispextern.h (string_buffer_position): Remove declaration.
14191 * print.c (strout): Remove parameter `multibyte', unused since
14192 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14194 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14195 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14196 All callers changed.
14198 * w32.c (_wsa_errlist): Use braces for struct initializers.
14200 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14201 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14202 All callers changed.
14203 (string_buffer_position): Likewise. Also, make static (it's never
14204 used outside xdisp.c).
14205 (cursor_row_p): Remove parameter `w', unused since
14206 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14208 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14209 All callers changed.
14211 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14213 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14219 (ns_update_auto_hide_menu_bar): New functions.
14220 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

14224 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14226 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14228 * nsmenu.m (runDialogAt): Remove argument to timer_check.
14230 2011-03-27 Glenn Morris <rgm@gnu.org>
14232 * syssignal.h: Replace RETSIGTYPE with void.
14233 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
14234 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
14235 Replace SIGTYPE with void everywhere.
14236 * s/usg5-4-common.h (SIGTYPE): Remove definition.

14239 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14241 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14242 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14244 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14246 * w32.c (read_unc_volume): Use parameter `henum', instead of
14247 global variable `wget_enum_handle'.
14249 * keymap.c (describe_vector): Remove parameters `indices' and
14250 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
14251 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
14253 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
14255 * keyboard.c (timer_check): Remove parameter `do_it_now',
14256 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
14257 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
14258 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
14260 * keyboard.c (read_char):
14261 * w32menu.c (w32_menu_display_help):
14262 * xmenu.c (show_help_event, menu_help_callback):
14263 Adjust calls to `show_help_echo'.
14265 * gtkutil.c (xg_maybe_add_timer):
14266 * keyboard.c (readable_events):
14267 * process.c (wait_reading_process_output):
14268 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14270 * insdel.c (adjust_markers_gap_motion):
14271 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
14272 (gap_left, gap_right): Don't call it.
14274 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

14345 2011-03-23 Julien Danjou <julien@danjou.info>
14347 * term.c (Fsuspend_tty, Fresume_tty):
14348 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14349 * window.c (temp_output_buffer_show):

14355 * cmds.c (internal_self_insert):
14356 * callint.c (Fcall_interactively):
14357 * buffer.c (Fkill_all_local_variables):
14358 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14360 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14361 unconditionally since it does the check itself.
14363 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14365 Fix more problems found by GCC 4.5.2's static checks.
14367 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14368 the first time through the loop, since we know p0 < p1 then.
14369 This also avoids a gcc -Wstrict-overflow warning.
14371 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14372 leading to a memory leak, possible in functions like
14373 load_charset_map_from_file that can allocate an unbounded number
14374 of objects (Bug#8318).
14376 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14377 that could (at least in theory) be that large.
14379 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14380 This is less likely to overflow, and avoids undefined behavior if
14381 overflow does occur. All callers changed. Use strtoul to scan
14382 for the unsigned long integer.
14383 (pint2hrstr): Simplify and tune code slightly.
14384 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14386 * scroll.c (do_scrolling): Work around GCC bug 48228.
14387 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
14389 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
14390 This also avoids a warning with gcc -Wstrict-overflow.
14391 (validate_x_resource_name): Simplify count usage.
14392 This also avoids a warning with gcc -Wstrict-overflow.
14394 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14397 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14399 * process.c (Fmake_network_process): Use socklen_t, not int,
14400 where POSIX says socklen_t is required in portable programs.
14401 This fixes a porting bug on hosts like 64-bit HP-UX, where
14402 socklen_t is wider than int (Bug#8277).
14403 (Fmake_network_process, server_accept_connection):
14404 (wait_reading_process_output, read_process_output):

14422 * terminfo.c: Include tparam.h, to check interfaces.
14423 (tparm): Make 1st arg a const pointer in decl. Put it at top level.

14479 clobbering (Bug#8298).
14480 * sysdep.c (sys_subshell): Likewise.
14481 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14483 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14484 This should get cleaned up, so that child_setup has the
14485 same signature on all platforms.
14487 * callproc.c (call_process_cleanup): Now static.
14488 (relocate_fd): Rename locals to avoid shadowing.

14649 (Fmemory_limit): Cast sbrk's returned value to char *.
14651 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14659 to use the following functions instead of these macros.
14660 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14661 EMACS_INT, since callers assume the returned value fits in int.
14662 (upcase1): Likewise, for UPCASE_TABLE.
14663 (uppercasep, lowercasep, upcase): New static inline functions.
14664 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14674 (regex_compile, re_match_2_internal): Mark locals as initialized.
14675 (RETALLOC_IF): Define only if needed.
14676 (WORDCHAR_P): Likewise. This one is never needed, but is used
14677 only in a comment talking about a compiler bug, so put inside
14678 the #if 0 of that comment.
14679 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14680 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14707 New macros, so that the caller can use some names other than
14708 gcpro1, gcpro2, etc.
14709 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14711 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14712 argument, for consistency with GCPRO2_VAR, etc: it is now the
14713 prefix of the variable, not the variable itself. All uses
14715 * dired.c (directory_files_internal, file_name_completion):
14716 Rename locals to avoid shadowing.
14718 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14719 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14720 dired.c's scmp function, had undefined behavior.
14721 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14722 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14723 * buffer.h: ... to here, because these macros use current_buffer,
14724 and the new implementation with inline functions needs to have
14725 current_buffer in scope now, rather than later when the macros
14727 (downcase, upcase1): New static inline functions.
14728 (DOWNCASE, UPCASE1): Reimplement using these functions.
14729 This avoids undefined behavior in expressions like
14730 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14731 from race conditions in accessing the global variables
14732 case_temp1 and case_temp2.
14733 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14734 * lisp.h (case_temp1, case_temp2): Remove their decls.
14735 * character.h (ASCII_CHAR_P): Move from here ...
14736 * lisp.h: ... to here, so that the inline functions mentioned
14737 above can use them.

14744 (file_name_as_directory): Use const pointers when appropriate.
14745 (Fexpand_file_name): Likewise. In particular, newdir might
14746 point at constant storage, so make it a const pointer.

14748 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14750 (Fset_file_times, Finsert_file_contents, auto_save_error):

14755 to avoid shadowing.
14757 * marker.c (bytepos_to_charpos): Remove; unused.
14759 * lisp.h (verify_bytepos, count_markers): New decls,
14760 so that gcc does not warn that these functions aren't declared.
14762 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14763 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14764 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14765 (copy_text): Remove unused local var.

14770 * buffer.c (fix_overlays_before): Mark locals as initialized.
14771 (fix_start_end_in_overlays): Likewise. This function should be
14772 simplified by using pointers-to-pointers, but that's a different

14775 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14776 (report_overlay_modification): Rename locals to avoid shadowing.

14781 to suppress a gcc -Wclobbered warning that does not seem to be right.
14782 (MAXPATHLEN): Define only if needed.
14784 * process.c (serial_open, serial_configure): Move decls from here ...
14785 * systty.h: ... to here, so that they can be checked.
14787 * fns.c (get_random, seed_random): Move extern decls from here ...
