298 * w32.c (init_environment): Change the default values of many
299 environment variables in dflt_envvars[] to NULL, to avoid pushing
300 them into environment when they were not already defined. Remove
301 the code that deletes site-lisp subdirectories from the default
302 value of EMACSLOADPATH, as it is no longer needed.
303 (check_windows_init_file): Now external, not static. Use
304 Vload_path as is, without adding anything, as this function is now
305 called when Vload_path is already set up.
307 * w32.h (check_windows_init_file): Add prototype.
309 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

314 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
315 any, in the DEFALT argument into the root of the Emacs build or
316 installation tree, as appropriate.
318 * callproc.c (init_callproc_1): Call decode_env_path instead of
319 doing its equivalent by hand.
320 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
321 the code that sets Vexec_path run on MS-Windows.
323 * lread.c (init_lread): Add comments to #ifdef's.
325 * msdos.c (dos_set_window_size, IT_update_begin)

333 Now constants, not macros.
335 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
337 Remove unnecessary casts involving pointers.
338 These casts are no longer needed now that we assume C89 or later,

340 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
341 (make_pure_float, make_pure_vector):
342 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

352 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
353 Remove unnecessary pointer casts.
354 * alloc.c (record_xmalloc): New function.
355 * lisp.h (record_xmalloc): New decl.
356 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
357 more like a function. This is because the pointer cast is not
358 needed. All uses changed.
359 * print.c (print_string, print_error_message): Avoid length recalc.
361 Improve fix for macroexp crash with debugging (Bug#12118).
362 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
363 ARRAY_MARK_FLAG when checking subscripts, because ASET is
364 not supposed to be invoked from the garbage collector.
365 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
366 (gc_aset): New function, which is like ASET but can be
367 used in the garbage collector.

381 (map_w32_filename): Improve commentary. Simplify switch.
382 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
383 headers (most versions of MinGW w32api don't).
384 (get_security_info, create_symbolic_link)
385 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
387 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
388 in the argument file name.

390 GetFileAttributes fails with network-related error codes.
391 (sys_rename): Diagnose renaming of a symlink when the user doesn't
392 have the required privileges.
393 (get_file_security_desc_by_name): Renamed from
394 get_file_security_desc.
395 (stat_worker): New function, with most of the guts of 'stat', and
396 with addition of handling of symlinks and support for 'lstat'. If
397 possible, get file's attributes and security information by
398 handle, not by name. Produce S_IFLNK bit for symlinks, when
400 (stat, lstat): New functions, call 'stat_worker'.
401 (symlink, readlink, careadlinkat): Rewritten to create and resolve
402 symlinks when the underlying filesystem supports them.
404 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
406 Fix macroexp crash on Windows with debugging (Bug#12118).
407 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
408 checking subscripts; problem introduced with the recent
409 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
410 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
411 since it's used in non-static inline functions now.
413 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
414 Don't assume buffer size fits in 'int'. Remove unused local.
416 Use C99-style 'extern inline' if available.
417 * buffer.h (BUFFER_INLINE):
418 * category.h (CATEGORY_INLINE):
419 * character.h (CHARACTER_INLINE):
420 * charset.h (CHARSET_INLINE):

434 * composite.c (COMPOSITE_INLINE):
435 * dispnew.c (DISPEXTERN_INLINE):
436 * sysdep.c (SYSTIME_INLINE):
437 Define to EXTERN_INLINE, so that the corresponding functions
438 are compiled into code.
439 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
440 (INLINE_HEADER_END): New macros.
441 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
442 since it's used in non-static inline functions now.

445 2012-08-02 Glenn Morris <rgm@gnu.org>
447 * s/: Remove empty directory.

461 hard-coding the path separator.
463 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
465 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
466 This how ASET and AREF are supposed to work, and makes

938 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
940 Fast save_excursion_save and save_excursion_restore.
941 * lisp.h (struct Lisp_Excursion): New data type.
942 (PVEC_EXCURSION): New pseudovector type.
943 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
944 to deal with it. Adjust comments.

958 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
959 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
960 emacs.c, as this is a more-suitable home. Had this been done earlier
961 the fix for 12036 would have avoided some of the problems noted in
962 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
963 would have been more obvious.
964 * emacs.c: Do not include <verify.h>; no longer needed.
965 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
966 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
967 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
968 Remove; now done in lisp.h.
969 * lisp.h (PUBLISH_TO_GDB): New macro.
970 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
971 (DATA_SEG_BITS): Use it.

973 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
974 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
975 not be usable in #if. This simplifies things.
977 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
979 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
981 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

984 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
985 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
986 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
987 Adjust to changes in lisp.h and emacs.c, by using
988 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
989 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
990 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
991 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
992 instead of gdb_valbits.
993 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
994 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
995 instead of gdb_array_mark_flag.
996 (xboolvector): Get size from $->size, not $->header.size.
997 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
998 (xreload, hook-run, hookpost-run): Remove.
999 * emacs.c: Include <verify.h>.
1000 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1001 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1003 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1004 (gdb_USE_LSB_TAG): New enum constants.
1005 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1006 Also define these as enum constants, so they're visible to GDB.
1007 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1008 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1009 as constants, so they're visible to GDB.
1010 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

1012 Now enum constants, not macros, so they're visible to GDB.
1013 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1014 more convenient now. All uses changed.
1015 (VALMASK) [USE_LSB_TAG]: Also define in this case.
1016 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.

1026 add argument, tune behavior, and adjust all callers.
1028 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1030 Use typedef for EMACS_INT, EMACS_UINT.
1031 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1032 than macros. This simplifies debugging in the usual case, since
1033 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1034 and it allows expressions involving EMACS_INT casts.
1035 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1037 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

1049 Adjust buffer text indirection counters at the end of Fkill_buffer.
1050 * buffer.c (Fkill_buffer): Adjust indirection counters when the
1051 buffer is definitely dead. This should really fix an issue reported
1052 by Christoph Scholtes again. (Bug#12007).
1053 (init_buffer_once): Initialize indirection counters of
1054 buffer_defaults and buffer_local_symbols (for sanity and safety).
1056 2012-07-24 Eli Zaretskii <eliz@gnu.org>
1058 * xdisp.c (init_iterator): Don't compute dimensions of truncation
1059 and continuation glyphs on tooltip frames, leave them at zero.
1060 Avoids continued lines in tooltips. (Bug#11832)
1062 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

1087 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1089 Swap buffer text indirection counters in Fbuffer_swap_text.
1090 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1091 This avoids crash reported by Christoph Scholtes at
1092 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1094 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1096 * nsmenu.m (Popdown_data): New struct.

1119 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
1121 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
1122 as it's limited by the amount of memory, not by INT_MAX.
1124 2012-07-21 Eli Zaretskii <eliz@gnu.org>
1126 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

1277 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1279 * eval.c (Fdefvar): Don't check constants since we only set the var if
1280 it's not yet defined anyway (bug#11904).

1283 * keyboard.c (command_loop_1): Set it.
1284 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
1285 were auto-added by the command loop (bug#11774).

1839 2012-07-11 Glenn Morris <rgm@gnu.org>
1841 * s/darwin.h, s/freebsd.h, s/netbsd.h:
1842 Move DONT_REOPEN_PTY to configure.
1844 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
1845 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
1847 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
1849 Remove "#define unix" that is no longer needed (Bug#11905).
1850 * s/aix4-2.h (unix): Remove; no longer needed.
1852 EMACS_TIME simplification (Bug#11875).
1853 This replaces macros (which typically do not work in GDB)
1854 with functions, typedefs and enums, making the code easier to debug.
1855 The functional style also makes code easier to read and maintain.
1856 * systime.h: Include <sys/time.h> on all hosts, not just if
1857 WINDOWSNT, since 'struct timeval' is needed in general.
1858 (EMACS_TIME): Now a typedef, not a macro.
1859 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
1861 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
1862 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
1863 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
1864 (EMACS_TIME_LE): Now functions, not macros.
1865 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
1866 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1867 which are not functions. All uses rewritten to use:
1868 (make_emacs_time): New function.
1869 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1870 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1871 not functions. All uses rewritten to use the following, respectively:
1872 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1873 (add_emacs_time, sub_emacs_time): New functions.
1874 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1875 * fileio.c (Fcopy_file):
1876 * xterm.c (XTflash): Get the current time closer to when it's used.
1877 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1881 Simplify by avoiding confusing use of strncpy etc.
1882 * doc.c (Fsnarf_documentation):
1883 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
1884 * frame.c (Fmake_terminal_frame):
1885 * gtkutil.c (get_utf8_string):
1887 * nsmenu.m (ns_update_menubar):
1888 * regex.c (regerror):
1889 Prefer memcpy to strncpy and strncat when either will do.
1890 * fileio.c (Fsubstitute_in_file_name):
1891 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1892 (menu_separator_name_p):
1893 * nsmenu.m (ns_update_menubar):
1894 Prefer memcmp to strncmp when either will do.
1895 * nsterm.m: Include <ftoastr.h>.
1897 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1898 Prefer snprintf to strncpy.
1899 * nsterm.m (ns_term_init):
1900 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1901 * nsterm.m (ns_term_init):
1902 Avoid the need for strncpy, by using build_string or
1903 make_unibyte_string directly. Use dtoastr, not snprintf.
1904 * process.c (Fmake_network_process): Diagnose service names that
1905 are too long, rather than silently truncating them or creating
1906 non-null-terminated names.
1907 (Fnetwork_interface_info): Likewise, for interface names.
1908 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1909 Prefer sprintf to strncat.
1910 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1911 Prefer vsnprintf to vsprintf + strncpy.
1913 2012-07-10 Glenn Morris <rgm@gnu.org>
1915 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1916 Clarify fallback case.
1918 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1920 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1921 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1922 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1923 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1924 where argument type is known to be a Lisp_Cons.
1926 2012-07-10 Tom Tromey <tromey@redhat.com>
1928 * bytecode.c (BYTE_CODE_THREADED): New macro.
1929 (BYTE_CODES): New macro. Replaces all old byte-code defines.
1930 (enum byte_code_op): New type.
1931 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
1932 (exec_byte_code): Use them. Use token threading when applicable.
1934 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1936 Optimize pure C strings initialization.
1937 * lisp.h (make_pure_string): Fix prototype.
1938 (build_pure_c_string): New function, defined as static inline. This
1939 provides a better opportunity to optimize away calls to strlen when
1940 the function is called with compile-time constant argument.
1941 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1942 argument, adjust users accordingly. Use build_pure_c_string where
1944 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1945 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1946 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1948 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1950 Avoid calls to strlen in miscellaneous functions.
1951 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1952 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1953 * lread.c (openp): Likewise.
1955 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1957 Avoid calls to strlen in path processing functions.
1958 * fileio.c (file_name_as_directory): Add comment. Change to add
1959 srclen argument and return the length of result. Adjust users
1961 (directory_file_name): Fix comment. Change to add srclen argument,
1962 swap 1st and 2nd arguments to obey the common convention. Adjust
1964 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1966 2012-07-10 Glenn Morris <rgm@gnu.org>
1968 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1969 Move PENDING_OUTPUT_COUNT definition to configure.
1971 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1972 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1973 * s/gnu.h (DATA_START): Move definitions to configure.
1975 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1976 We include usg5-4-common.h, which defines them both.
1978 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1979 O_RDONLY already includes it).
1981 Stop ns builds setting the EMACSLOADPATH environment variable.
1982 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1983 Now it does not set EMACSLOADPATH, just returns the load-path string.
1984 * nsterm.h: Update accordingly.
1985 * lread.c [HAVE_NS]: Include nsterm.h.
1986 (init_lread) [HAVE_NS]: Use ns_load_path.
1987 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1989 2012-07-09 Glenn Morris <rgm@gnu.org>
1991 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1992 since the included bsd-common.h does so.
1994 Stop ns builds setting the EMACSPATH environment variable.
1995 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1996 (ns_init_paths): Do not set EMACSPATH.
1997 * nsterm.h (ns_exec_path): Add it.
1998 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2001 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2003 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2005 * process.c (wait_reading_process_output): 'waitchannels' was unset
2006 when read_kbd || !NILP (wait_for_cell); fix this.
2008 Add GCC-style 'const' attribute to functions that can use it.
2009 * character.h (char_resolve_modifier_mask):
2010 * keyboard.h (make_ctrl_char):
2011 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
2012 (init_character_once, next_almost_prime, init_fns, init_image)
2013 (flush_pending_output, init_sound):
2014 * mem-limits.h (start_of_data):
2015 * menu.h (finish_menu_items):
2016 Add ATTRIBUTE_CONST.
2017 * emacs.c (DEFINE_DUMMY_FUNCTION):
2018 Declare the dummy function with ATTRIBUTE_CONST.
2019 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2020 Add decls with ATTRIBUTE_CONST.
2022 Minor improvements to make_formatted_string.
2023 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2024 where int is good enough, as vsprintf returns an int.
2025 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2027 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2029 Use make_formatted_string to avoid double length calculation.
2030 * lisp.h (make_formatted_string): New prototype.
2031 * alloc.c (make_formatted_string): New function.
2032 * buffer.c (Fgenerate_new_buffer_name): Use it.
2033 * dbus.c (syms_of_dbusbind): Likewise.
2034 * editfns.c (Fcurrent_time_zone): Likewise.
2035 * filelock.c (get_boot_time): Likewise.
2036 * frame.c (make_terminal_frame, set_term_frame_name)
2037 (x_report_frame_params): Likewise.
2038 * image.c (gs_load): Likewise.
2039 * minibuf.c (get_minibuffer): Likewise.
2040 * msdos.c (dos_set_window_size): Likewise.
2041 * process.c (make_process): Likewise.

2052 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
2054 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2056 Move marker debugging code under MARKER_DEBUG.
2057 * marker.c (MARKER_DEBUG): Move marker debugging code under
2058 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2059 for bootstrap with --enable-checking (~3x slowdown reported
2060 by Juanma Barranquero <lekktu@gmail.com>).
2061 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2063 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2065 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2066 See <http://bugs.gnu.org/11825#29>.
2068 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2070 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2071 has no font, use the frame's font. (Bug#11813)
2072 (display_line): Add commentary about displaying truncation glyphs
2074 (produce_special_glyphs): Move here from term.c.
2076 * term.c (produce_special_glyphs): Move to xdisp.c.
2078 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2081 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2083 * xdisp.c (display_line): Avoid warning about implicit declaration
2086 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2088 * lisp.h: Remove empty conditional.
2090 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2092 * lread.c (load_path_check): Now static.
2094 Fix some minor --with-ns problems found by static checking.
2095 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2096 (x_set_font) [!HAVE_X_WINDOWS]:
2097 * image.c (xpm_load_image) [HAVE_NS]:
2098 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2099 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2100 Remove unused local.
2101 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2102 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2103 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2104 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2105 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2106 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2107 Fix pointer signedness problem.
2108 * xfaces.c (FRAME_X_FONT_TABLE):
2109 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2111 2012-07-07 Glenn Morris <rgm@gnu.org>
2113 * lread.c (load_path_check): New function, split from init_lread.
2114 (init_lread): Reorganize. Motivation:
2115 If EMACSLOADPATH is set, check/warn about that rather than the
2116 defaults, which we are not going to use. Hence we can remove
2117 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2118 Don't warn if site-lisp directories are missing.
2119 If not installed, start from a blank load-path, since
2120 PATH_LOADSEARCH refers to the eventual installation directories.
2122 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2124 Support truncation and continuation glyphs on GUI frames, when
2125 fringes are disabled. (Bug#11832)
2126 * xdisp.c (init_iterator): Get dimensions of truncation and
2127 continuation glyphs even if on GUI frames. Adjust
2128 it->last_visible_x on GUI frames when the left or right fringes,
2129 or both, are absent.
2130 (start_display, move_it_in_display_line_to): Handle the case of a
2131 GUI frame without a fringe to display continuation or truncation
2133 (insert_left_trunc_glyphs): Support GUI frames: make sure
2134 truncation glyphs overwrite enough glyphs from the current line to
2135 have sufficient space in pixels.
2136 (display_line): Support truncation and continuation glyphs on GUI
2137 frames. If some spare pixels are left on the line after inserting
2138 the truncation glyphs, fill that space with a stretch glyph of a
2139 suitably computed width.
2141 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2142 produce_glyphs, to support GUI sessions.
2144 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2146 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2148 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2150 Do not require float-time's arg to fit in time_t (Bug#11825).
2151 This works better on hosts where time_t is unsigned, and where
2152 float-time is applied to the (negative) difference between two times.
2153 * editfns.c (decode_time_components): Last arg is now double *,
2154 not int *, and means to store all the result as a double, without
2155 worrying about whether the seconds part fits in time_t.
2156 All callers changed.
2157 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2158 All callers changed.
2159 (Ffloat_time): Do not fail merely because the specified time falls
2160 outside of time_t range.
2162 2012-07-07 Glenn Morris <rgm@gnu.org>
2164 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
2165 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
2166 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
2168 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2170 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2171 Update dependencies.
2173 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2175 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2177 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
2178 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
2179 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2180 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2181 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2182 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2184 * xfont.c (compare_font_names): Redo to omit the need for casts.
2186 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2188 * xfns.c (Fx_change_window_property): Doc fix.
2189 * w32fns.c (Fx_change_window_property): Doc fix.
2191 * w32fns.c (Fx_window_property): Accept the same arguments as the
2192 X Windows version. Doc fix.
2193 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2195 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2196 Eli Zaretskii <eliz@gnu.org>
2198 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2199 Windows-specific code from nt/config.nt moved here.
2200 Obsolete settings removed.
2202 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2204 * process.c: Avoid unnecessary calls to gettime.
2205 (wait_reading_process_output): Don't get the time of day
2206 when gobbling data immediately and not waiting, as there's no need
2207 for it in that case. This removes a FIXME.
2209 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2211 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2212 is defined (Bug#11768).
2214 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2216 Fix marker debugging code.
2217 * marker.c (byte_char_debug_check): Do not perform the check
2218 if buffer is not multibyte.
2219 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2220 Call byte_char_debug_check with correct arguments.
2222 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2224 Compile marker debugging code only if ENABLE_CHECKING is defined.
2225 * marker.c (byte_char_debug_check, count_markers):
2226 Use only if ENABLE_CHECKING is defined.
2227 (byte_debug_flag): Remove.
2228 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2229 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2231 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2233 Avoid code repetition in marker-related functions.
2234 * marker.c (attach_marker): New function.
2235 (Fset_marker, set_marker_restricted, set_marker_both)
2236 (set_marker_restricted_both): Use it.
2237 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2238 Consistently rename charno to charpos.
2239 (marker_position): Add eassert.
2240 (marker_byte_position): Convert to eassert.
2242 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2244 Simplify list operations in unchain_overlay and unchain_marker.
2245 * buffer.c (unchain_overlay): Simplify. Add comment.
2246 * marker.c (unchain_marker): Simplify. Fix comments.
2248 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

2256 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2257 (save_restriction_save): Use build_marker.
2258 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2259 * window.c (save_window_save): Likewise.
2261 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2263 Do not use Fdelete_overlay in delete_all_overlays
2264 to avoid redundant calls to unchain_overlay.
2265 * buffer.c (drop_overlay): New function.
2266 (delete_all_overlays, Fdelete_overlay): Use it.
2267 * minibuf.c (get_minibuffer): Fix comment.
2269 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2271 Port to OpenBSD 5.1 amd64.
2272 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2273 This is needed for OpenBSD, and should be harmless on all BSD systems.
2274 Also, include <sys/sysctl.h>, as it should be available on all
2275 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2276 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2277 use p_pid member, not kp_proc.pid.
2279 2012-07-06 Glenn Morris <rgm@gnu.org>
2281 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2283 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2285 More xmalloc and related cleanup.
2286 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2287 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2293 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2294 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2296 Omit needless casts involving void * pointers and allocation.
2297 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2298 as the former is more robust if P's type is changed.
2299 Prefer xzalloc to xmalloc + memset 0.
2300 Simplify malloc-or-realloc to realloc.
2301 Don't worry about xmalloc returning a null pointer.
2302 Prefer xstrdup to xmalloc + strcpy.
2303 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2305 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2306 alloca of a constant.
2308 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2310 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2311 hscroll is larger than the line width. Fixes long and futile
2312 looping inside extend_face_to_end_of_line (on a TTY) producing
2313 glyphs that are not needed and thrown away.
2315 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2317 * marker.c (set_marker_restricted_both): Simplify by using
2320 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2322 * editfns.c (region_limit): Simplify by using clip_to_bounds.
2324 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
2326 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
2327 not defined (Bug#11768).
2328 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2329 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2330 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2331 followed by gtk_box_set_homogeneous (Bug#11768).
2332 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2333 (update_theme_scrollbar_width, xg_create_scroll_bar):
2334 Use gtk_scrollbar_new (Bug#11768).
2335 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2336 (is_box_type): New function (Bug#11768).
2337 (xg_tool_item_stale_p): Call is_box_type.
2338 (xg_initialize): Get settings by calling gtk_settings_get_for_screen

2343 * xdisp.c (window_hscroll_limited): New function.
2344 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2345 coordinates when window's hscroll is set to insanely large
2348 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2350 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2353 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2356 * lisp.h (xzalloc): New prototype. Omit needless casts.
2357 * alloc.c (xzalloc): New function. Omit needless casts.

2411 * fileio.c (time_error_value): Check the right error number.
2412 Problem reported by Troels Nielsen in
2413 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2415 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2417 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2418 This should be fixed in a better way; see Eli Zaretskii in
2419 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2420 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2422 * fileio.c (time_error_value): Rename from special_mtime.
2423 The old name's problems were noted by Eli Zaretskii in
2424 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2426 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2427 This variable's comment says Emacs needs at least one GDB-visible
2428 symbol of type enum pvec_type, to work around GDB problems.
2429 The symbol's value doesn't matter.
2431 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2432 that causes compilation to fail on pre-C99 compilers.
2434 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2436 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2437 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2439 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2441 * buffer.c (init_buffer_once): Fix initialization of
2442 headers for buffer_defaults and buffer_local_symbols.
2443 Reported by Juanma Barranquero <lekktu@gmail.com>.
2445 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2447 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2448 * lisp.h (enum pvec_type): Use fewer bits.
2449 (PSEUDOVECTOR_SIZE_BITS): New constant.
2450 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2451 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2452 change in pvec_type.
2453 (PSEUDOVECTOR_TYPEP): New macro.
2454 (TYPED_PSEUDOVECTORP): Use it.
2455 * fns.c (internal_equal): Adapt code to extract pvectype.
2456 * emacs.c (gdb_pvec_type): Update type.
2457 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2458 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2459 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2460 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2461 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2462 abusing vector->header.next.nbytes.
2463 (live_vector_p): Use PVEC_TYPE.
2464 (mark_object): Adapt code to extract pvectype. Use switch.
2466 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2468 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2469 Tighten new eassert a bit.
2471 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2473 Fix compilation with --enable-gcc-warnings and -O1
2475 * doprnt.c (doprnt): Change type of tem to int, initialize
2476 to avoid compiler warning. Add eassert.
2477 * search.c (simple_search): Initialize match_byte to avoid
2478 compiler warning. Add eassert.
2480 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2482 Avoid weird behavior with large horizontal scrolls.
2483 Without this change, for example, large hscroll values would
2484 mess up Emacs's display on Fedora 15 x86, presumably due to
2485 overflows in int calculations in the display code.
2486 Also, if buffers had long lines, Emacs would freeze.
2487 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2488 (set_window_hscroll): New function, containing the old guts of
2489 Fset_window_hscroll. Return the clipped value.
2490 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2491 This avoids the need to check against PTRDIFF_MAX.
2493 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2495 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2497 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2499 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2501 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2502 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2503 since GCC 4.4.6 issues a bogus warning for them.
2505 Fix bugs in file timestamp newness comparisons.
2506 * fileio.c (Ffile_newer_than_file_p):
2507 * lread.c (Fload): Use full timestamp resolution of files,
2508 not just the 1-second resolution, so that files that are only
2509 slightly newer still count as newer.
2510 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2511 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2513 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2515 * fileio.c: Improve handling of file time marker. (Bug#11852)
2516 (special_mtime): New function.
2517 (Finsert_file_contents, Fverify_visited_file_modtime):
2518 Use it to set special mtime values consistently.
2520 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2522 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2523 marker for non-existing file. (Bug#11852)
2525 2012-07-03 Glenn Morris <rgm@gnu.org>
2527 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2528 and did not make it into globals.h).
2530 2012-07-03 Tom Tromey <tromey@redhat.com>
2532 * window.c (Fset_window_margins, Fset_window_fringes)
2533 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2534 * textprop.c (Fprevious_property_change): No longer static.
2535 * syntax.c (Fsyntax_table_p): No longer static.
2536 * process.c (Fget_process, Fprocess_datagram_address): No longer

2556 * dispextern.h: Remove EXFUNs.
2557 * intervals.h: Remove EXFUNs.
2558 * fontset.h: Remove EXFUN.
2559 * font.h: Remove EXFUNs.
2560 * dosfns.c (system_process_attributes): Remove EXFUN.
2561 * keymap.h: Remove EXFUNs.
2562 * lisp.h: Remove EXFUNs.
2563 * w32term.h: Remove EXFUNs.
2564 * window.h: Remove EXFUNs.
2565 * xsettings.h: Remove EXFUN.
2566 * xterm.h: Remove EXFUN.
2568 2012-07-03 Glenn Morris <rgm@gnu.org>
2570 * lisp.h (Frandom): Make it visible to C.
2571 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2572 buffer for invisible buffers. (Bug#1229)
2574 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2576 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2577 values which aren't power of 2.
2578 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2579 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2582 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2584 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2586 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2588 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2590 * alloc.c (allocate_vector_block): Remove redundant
2591 calls to mallopt if DOUG_LEA_MALLOC is defined.
2592 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2593 avoid calls to mallopt if zero_vector is returned.
2595 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2597 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2598 is enabled, avoid dereferencing NULL current_sblock if
2601 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2603 Cleanup basic buffer management.
2604 * buffer.h (struct buffer): Change layout to use generic vector
2605 marking code. Fix some comments. Change type of 'clip_changed'
2606 to bitfield. Remove unused #ifndef old.
2607 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2608 (GET_OVERLAYS_AT): Fix indentation.
2609 (for_each_per_buffer_object_at): New macro.
2610 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2612 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2613 * alloc.c (allocate_buffer): Adjust to match new layout of
2614 struct buffer. Fix comment.
2615 (mark_overlay): New function.
2616 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2617 Lisp area of struct buffer.
2618 (mark_object): Use it. Adjust marking of misc objects
2619 and related comments.
2621 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2623 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2624 wrapper that is not needed because the wrapped code is a no-op (zero
2625 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2626 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2628 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2630 * alloc.c (mark_buffer): Simplify. Remove prototype.
2631 (mark_object): Add comment. Reorganize marking of vector-like
2632 objects. Use CHECK_LIVE for all vector-like objects except buffers
2633 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2634 redundant calls to mark_vectorlike for bool vectors.
2636 2012-06-30 Glenn Morris <rgm@gnu.org>
2638 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2640 * epaths.in (PATH_SITELOADSEARCH): New.
2641 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2642 This is rather than relying on --enable-locallisppath elements
2643 having "site-lisp" in their names. (Bug#10208#25, 11658)
2645 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2647 * w32proc.c (sys_select): Accept and ignore one more argument.
2649 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2651 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2652 (pselect) [!MS_DOS]: Redirect to sys_select.
2654 * sysdep.c: Don't include dos.h and dosfns.h.
2656 * process.c (sys_select):
2657 * msdos.c (sys_select): Accept one more argument and ignore it.
2659 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2660 adapt data types and code to that.
2663 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2664 which clashes with the gnulib function of the same name.
2666 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2668 * font.c (font_style_to_value, font_style_symbolic)
2669 (font_prop_validate_style): Add type checks for values in
2672 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2674 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2677 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2679 * xdisp.c (try_window_id): Undo last change.
2681 * w32.c (getwd): Adjust commentary about startup_dir.
2682 (init_environment): Always call sys_access, even in non-MSVC
2683 builds. Don't chdir to the directory of the Emacs executable.
2684 This undoes code from 1997 which was justified by the need to
2685 "avoid conflicts when removing and renaming directories". But its
2686 downside was that every relative file name was being interpreted
2687 relative to the directory of the Emacs executable, which can never
2688 be TRT. In particular, it broke sys_access when called with
2689 relative file names.
2690 (sys_access): Map GetLastError to errno.
2692 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2694 * window.h (struct window): Change type of 'fringes_outside_margins'
2695 to bitfield. Fix comment. Adjust users accordingly.
2696 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2698 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2701 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2703 * gnutls.c (emacs_gnutls_handshake):
2704 Add QUIT to make the loop interruptible.
2706 2012-06-29 Glenn Morris <rgm@gnu.org>
2708 * charset.c (init_charset): Make lack of etc/charsets fatal.
2710 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2712 * editfns.c (region_limit): Fix type mismatch.
2714 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2716 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2717 undefined. Convert from xassert to eassert.
2718 * nsmenu.m: Convert from xassert to eassert.
2719 * nsterm.m: Likewise.
2721 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2723 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2725 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2727 Avoid integer overflow on scroll-left and scroll-right.
2728 * window.c (HSCROLL_MAX): New macro.
2729 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2730 overflow when requested scroll falls outside ptrdiff_t range.
2732 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2734 * window.h (struct window): Change type of 'hscroll',
2735 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2736 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2737 Adjust users accordingly.
2738 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2739 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2740 from EMACS_INT to ptrdiff_t.
2741 (make_window): Omit redundant initialization.
2743 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2745 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2747 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2749 * window.h (struct window): Change type of 'use_time' and
2750 'sequence_number' from Lisp_Object to int.
2751 * frame.c (make_frame): Adjust users accordingly.
2752 * print.c (print_object): Likewise.
2753 * window.c (select_window, Fwindow_use_time, make_parent_window)
2754 (make_window): Likewise.

2884 Use sprintf return value instead of invoking strlen on result.
2885 In the old days this wasn't portable, since some sprintf
2886 implementations returned char *. But they died out years ago and
2887 Emacs already assumes sprintf returns int.
2888 Similarly for float_to_string.
2889 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2897 Use sprintf or float_to_string result to avoid need to call strlen.
2898 * data.c (Fnumber_to_string):
2899 Use make_unibyte_string, since the string must be ASCII.
2900 * lisp.h, print.c (float_to_string): Now returns int length.
2901 * term.c (produce_glyphless_glyph):
2902 Use sprintf result rather than recomputing it.
2904 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

2933 * xfns.c (x_window): Remove redundant cast.
2935 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2937 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2938 `const char *' to `char *' to avoid compiler warning.
2940 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2942 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2943 instead of truncating it to 63 (admittedly a generous limit).

3002 * dispnew.c (Fsleep_for, sit_for):
3003 * keyboard.c (kbd_buffer_get_event):
3004 * process.c (Faccept_process_output):
3005 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3006 This improves on the previous patch, which introduced a bug
3007 when time_t is unsigned and as wide as intmax_t.
3008 See <http://bugs.gnu.org/9000#51>.
3010 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3039 language ID in the event parameters.
3041 * w32term.c (w32_read_socket): Put the new keyboard codepage into

3073 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3075 Support higher-resolution time stamps (Bug#9000).
3076 The time stamps are only nanosecond-resolution at the C level,
3077 since that's the best that any real-world system supports now.
3078 But they are picosecond-resolution at the Lisp level, as that's
3079 easy, and leaves room for future OS improvements.
3081 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3084 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3085 Don't get current time unless it's needed.
3087 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3088 now provides it if it's absent.
3089 (start_atimer): Port to higher-res time stamps.
3090 Check for time stamp overflow. Don't get current time more
3091 often than is needed.
3093 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3094 Include systime.h, not time.h.
3095 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3097 * dired.c: Include stat-time.h.
3098 (Ffile-attributes): File times now have higher resolution.

3101 (struct image): Timestamp now has higher resolution.
3103 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3104 has at least microseconds now. All uses removed.
3105 (update_frame, update_single_window, update_window, update_frame_1)
3106 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3108 * editfns.c (time_overflow): Now extern.
3109 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3110 (float-time, Fformat_time_string, Fcurrent_time_string)

3115 (make_time): Now static.
3116 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3117 Report an error if the time is invalid, rather than having the caller
3120 * fileio.c: Include <stat-time.h>
3121 (Fcopy_file): Copy higher-resolution time stamps.
3122 Prefer to set the time stamp via a file descriptor if that works.
3123 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3124 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3125 (Fvisited_file_modtime, Fset_visited_file_modtime):
3126 Support higher-resolution time stamps.
3128 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3130 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3132 * image.c (prepare_image_for_display, clear_image_cache)
3133 (lookup_image): Port to higer-resolution time stamps.
3135 * keyboard.c (start_polling, bind_polling_period):
3136 Check for time stamp overflow.
3137 (read_char, kbd_buffer_get_event, timer_start_idle)
3138 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3139 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3140 Port to higher-resolution time stamps. Do not assume time_t is signed.
3141 (decode_timer): New function. Timers are now vectors of length 9,
3142 not 8, to accommodate the picosecond component.
3143 (timer_check_2): Use it.
3145 * nsterm.m (select_timeout, timeval_subtract): Remove.
3146 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3147 as they're a bit more accurate and handle overflow better.
3148 (ns_select): Change prototype to be compatible with pselect.
3149 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3150 * nsterm.h (ns_select): Adjust prototype.
3152 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3153 us-resolution time stamps.
3154 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3156 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3158 * lisp.h (time_overflow): New decl.
3159 (wait_reading_process_output): First arg is now intmax_t, not int,
3160 to accommodate larger waits.
3162 * process.h (struct Lisp_Process.read_output_delay):
3163 Now counts nanoseconds, not microseconds.
3164 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3166 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3167 (wait_reading_process_output):
3168 Port to ns-resolution time stamps.
3169 (Faccept_process_output, wait_reading_process_output):
3170 Check for time stamp overflow. Do not assume time_t is signed.
3171 (select_wrapper): Remove; we now use pselect.
3172 (Fprocess_attributes): Now generates ns-resolution time stamps.
3174 * sysdep.c: Include utimens.h. Don't include utime.h
3175 or worry about struct utimbuf; gnulib does that for us now.
3176 (gettimeofday): Remove; gnulib provides a substitute.
3177 (make_timeval): New function.
3178 (set_file_times): Now sets ns-resolution time stamps.
3179 New arg FD; all uses changed.
3180 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3181 (system_process_attributes):
3182 Now returns ns-resolution time stamp. All uses changed.
3183 Check for time stamp overflow.
3185 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3186 provides a substitute now.
3188 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3189 since it guarantees struct timespec.
3190 (EMACS_TIME): Now struct timespec, so that we can support
3191 ns-resolution time stamps.
3192 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3193 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3194 (EMACS_USECS): Remove.
3195 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3196 so multiply the arg by 1000 before storing it.
3197 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3199 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3200 Port to ns-resolution time stamps.
3201 (EMACS_TIME_NEG_P): Remove; replaced by....
3202 (EMACS_TIME_SIGN): New macro.
3203 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3204 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

3206 (make_timeval, make_lisp_time, decode_time_components): New decls.
3207 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3208 that it mishandled time_t overflow. You can't compare by subtracting!
3209 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3210 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3212 * term.c: Include <sys/time.h>.
3213 (timeval_to_Time): New function, for proper overflow wraparound.
3214 (term_mouse_position, term_mouse_click): Use it.

3218 (Fprimitive_undo): Use them when restoring time stamps.
3220 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3221 (w32_get_internal_run_time):
3222 Port to higher-resolution Emacs time stamps.
3223 (ltime): Now accepts single 64-bit integer, as that's more convenient
3226 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3228 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3229 for compatibility with pselect. Support ns-resolution time stamps.
3231 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3233 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3234 Check for time stamp overflow, and support ns-resolution time stamps.
3236 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3237 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3238 (timeval_subtract): Remove; no longer needed.

3302 gets killed during executing of this function (Bug#11665).

3335 * coding.c (produce_chars): Use ptrdiff_t, not int.
3337 * xterm.c (x_draw_underwave): Check for integer overflow.

3524 as the union type is for debugging, not for production.
3525 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3526 Use an inline function on all platforms when using the union type,
3527 since this is simpler and 'static inline' can be used portably

3672 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3673 would mishandle a string argument "Xc" if X was a multibyte

3718 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
3720 * keyboard.c: Export real-this-command to Elisp.
3721 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
3722 and DEFVAR it. Update all users.
3724 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
3726 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3728 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3729 Convert pctcpu and pctmem to Lisp float properly.
3730 Let the compiler fold better, as 100.0/0x8000 is exact.
3732 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3734 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3737 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3739 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3741 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3743 For a 'struct window', replace some Lisp_Object fields to
3744 bitfields where appropriate, remove unused fields.
3745 * window.h (struct window): Remove unused 'last_mark_x' and
3746 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3747 change it's type from Lisp_Object to bitfield.
3748 Change type of 'force_start', 'optional_new_start',
3749 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3750 fields from Lisp_Object to bitfield. Adjust users accordingly.
3752 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3754 Pacify gcc -Wdouble-precision when using Xaw.
3755 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3756 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3757 Use 'float' consistently, rather than 'float' in most places
3758 and 'double' in a couple of places.
3760 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3762 * xdisp.c (handle_stop): Detect whether we have overlay strings
3763 loaded by testing it->current.overlay_string_index to be
3764 non-negative, instead of checking whether n_overlay_strings is
3765 positive. (Bug#11587)
3767 2012-05-31 Chong Yidong <cyd@gnu.org>
3769 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3771 * doc.c (Fsubstitute_command_keys): Doc fix.
3773 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3775 * search.c (search_buffer): Remove calls to
3776 r_alloc_inhibit_buffer_relocation, as it is now called by
3777 maybe_unify_char, which was the cause of relocation of buffer text
3780 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3782 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3783 for the duration of call to load_charset, to avoid problems with
3784 callers of maybe_unify_char that access buffer text through C
3787 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3788 decrement the inhibition flag, instead of just setting or
3791 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3793 Remove obsolete '#define static' cruft.
3794 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3795 This #undef was "temporary" in 2000; it is no longer needed
3796 now that '#define static' has gone away.
3797 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3798 (gray_bitmap_bits): Remove; no longer needed.
3799 All uses replaced with definiens.
3800 * xterm.c: Include "bitmaps/gray.xbm".
3802 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3804 Clean up __executable_start, monstartup when --enable-profiling.
3805 The following changes affect the code only when profiling.
3806 * dispnew.c (__executable_start): Rename from safe_bcopy.
3807 Define only on platforms that need it.
3808 * emacs.c: Include <sys/gmon.h> when profiling.
3809 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3810 (__executable_start): Remove decl, since lisp.h does it now.
3811 (safe_bcopy): Remove decl; no longer has that name.
3812 (main): Coalesce #if into single bit of code, for simplicity.
3813 Cast pointers to uintptr_t, since standard libraries want integers
3815 * lisp.h (__executable_start): New decl.
3817 2012-05-31 Glenn Morris <rgm@gnu.org>
3819 * image.c (Fimagemagick_types): Doc fix.
3821 2012-05-30 Jim Meyering <meyering@redhat.com>
3823 * callproc.c (Fcall_process_region): Include directory component
3824 in mkstemp error message (Bug#11586).
3826 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3828 * alloc.c, lisp.h (make_pure_vector): Now static.
3830 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

3835 * data.c (Fdefalias): Purify definition, except for keymaps.
3836 (Qdefun): Move from eval.c.
3837 * lisp.h (Qdefun): Remove.
3838 * lread.c (read1): Tiny simplification.
3840 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3842 Do not create empty overlays with the evaporate property (Bug#9642).
3843 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3844 Bug#9642, but explicitly check that the buffer the overlay would
3845 be moved to is live and rearrange lines to make sure that errors
3846 will not put the overlay in an inconsistent state.
3847 (Fdelete_overlay): Cosmetics.
3849 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3851 * w32term.c (my_bring_window_to_top): New function.
3852 (x_raise_frame): Use handle returned by DeferWindowPos, which
3853 could be different from the original one.
3854 Call my_bring_window_to_top instead of my_set_foreground_window.
3857 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3858 by calling BringWindowToTop.
3860 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3861 (WM_EMACS_END): Increase by one.
3863 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3865 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3866 This avoids undefined behavior that might cause the eassert
3867 to not catch an out-of-range value.
3869 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3871 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3872 Update dependencies.
3874 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3876 * bidi.c (bidi_mirror_char): Fix last change.
3878 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3880 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3881 when referring to sectname field in printf format.
3883 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3885 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3886 Only r_alloc_inhibit_buffer_relocation needed to be added;
3887 the others were already declared.
3889 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3890 before checking whether it's out of range. Put the check inside
3892 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3894 2012-05-27 Ken Brown <kbrown@cornell.edu>
3896 * callproc.c (Fcall_process): Restore a line that was accidentally
3897 commented out in the 2011-02-13 change (bug#11547).
3899 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3901 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3902 defined on ralloc.c.
3904 * buffer.c [REL_ALLOC]: Remove prototypes of
3905 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3906 they are now on lisp.h.
3908 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3910 * search.c (search_buffer): Use it to inhibit relocation of buffer
3911 text while re_search_2 is doing its job, because re_search_2 is
3912 passed C pointers to buffer text. (Bug#11519)
3914 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3917 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3918 state after an additional call to move_it_in_display_line_to, keep
3919 the values of it->max_ascent and it->max_descent found for the
3921 (pos_visible_p): Revert the comparison against bottom_y to what it
3922 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3925 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3927 Fix coding-related core dumps with gcc -ftrapv.
3928 The code was computing A - B, where A and B are pointers, and B is
3929 random garbage. This can lead to core dumps on platforms that
3930 have special pointer registers, and it also leads to core dumps on
3931 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3932 A - B only when B is initialized properly.
3933 * coding.c (coding_set_source, coding_set_destination): Return void.
3934 (coding_change_source, coding_change_destinations): New functions,
3935 with the old behaviors of coding_set_source and coding_set_destination.
3936 All callers that need an offset changed to use these new functions.
3938 2012-05-26 Glenn Morris <rgm@gnu.org>
3940 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3942 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3944 Extend mouse support on W32 text-mode console.
3945 * xdisp.c (draw_row_with_mouse_face):
3946 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3948 * w32console.c: Include window.h.
3949 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3951 (initialize_w32_display): Initialize mouse-highlight data.
3953 * w32inevt.c: Include termchar.h and window.h.
3954 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3955 moves, call note_mouse_highlight. If help_echo changed, call
3956 gen_help_event to produce help-echo message in the echo area.
3957 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3960 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3962 * lread.c (read1): Simplify slightly to avoid an overflow warning
3963 with GCC 4.7.0 on x86-64.
3965 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3967 * bidi.c (bidi_mirror_char): Revert last change: an int is
3968 definitely wide enough here.
3970 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3972 Fix integer width and related bugs (Bug#9874).
3973 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3974 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3975 (string_bytes, check_sblock, allocate_string_data):
3976 (compact_small_strings, Fmake_bool_vector, make_string)
3977 (make_unibyte_string, make_multibyte_string)
3978 (make_string_from_bytes, make_specified_string)
3979 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3980 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3982 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3983 (allocate_pseudovector):
3984 Use int, not EMACS_INT, where int is wide enough.
3985 (inhibit_garbage_collection, Fgarbage_collect):
3986 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3987 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3988 int might not be wide enough.
3989 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3990 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3991 (bidi_at_paragraph_end, bidi_find_paragraph_start)
3992 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3993 (bidi_level_of_next_char, bidi_move_to_visually_next):
3994 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3995 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3996 (Fkill_buffer, Fset_buffer_major_mode)
3997 (advance_to_char_boundary, Fbuffer_swap_text)
3998 (Fset_buffer_multibyte, overlays_at, overlays_in)
3999 (overlay_touches_p, struct sortvec, record_overlay_string)
4000 (overlay_strings, recenter_overlay_lists)
4001 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4002 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4003 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4004 (Foverlay_recenter, last_overlay_modification_hooks_used)
4005 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4006 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4007 (validate_region): Omit unnecessary test for b <= e,
4008 since that's guaranteed by the previous test.
4009 (adjust_overlays_for_delete): Avoid pos + length overflow.
4010 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4011 (report_overlay_modification):
4012 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4013 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4014 Omit pointer cast, which isn't needed anyway, and doesn't work
4015 after the EMACS_INT -> ptrdiff_t change.
4016 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4017 * buffer.h: Adjust decls to match defn changes elsewhere.
4018 (struct buffer_text, struct buffer):
4019 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4020 Use EMACS_INT, not int, where int might not be wide enough.
4021 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4022 not int, to avoid needless 32-bit limit on 64-bit hosts.
4023 (exec_byte_code): Use tighter memory-full test, one that checks
4024 for alloca overflow. Don't compute the address of the object just
4025 before an array, as that's not portable. Use EMACS_INT, not
4026 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4027 * callint.c (Fcall_interactively):
4028 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4029 * callproc.c (call_process_kill, Fcall_process):
4030 Don't assume pid_t fits into an Emacs fixnum.
4031 (call_process_cleanup, Fcall_process, child_setup):
4032 Don't assume pid_t fits into int.
4033 (call_process_cleanup, Fcall_process, delete_temp_file)
4034 (Fcall_process_region):
4035 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4036 (Fcall_process): Simplify handling of volatile integers.
4037 Use int, not EMACS_INT, where int will do.
4038 * casefiddle.c (casify_object, casify_region, operate_on_word)
4039 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4040 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4041 (casify_object): Avoid integer overflow when overallocating buffer.
4042 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4043 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4044 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4045 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4046 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4047 integers are now checked earlier. All uses replaced with XINT.
4049 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4050 For CCL_MapSingle, check that content and value are in int range.
4051 (ccl_driver, Fregister_code_conversion_map):
4052 Check that Vcode_version_map_vector is a vector.
4053 (resolve_symbol_ccl_program): Check that vector header is in range.
4054 Always copy the vector, so that we can check its contents reliably
4055 now rather than having to recheck each instruction as it's being
4056 executed. Check that vector words fit in 'int'.
4057 (ccl_get_compiled_code, Fregister_ccl_program)
4058 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4059 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4060 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4061 contents are in range.
4062 (Fccl_execute_on_string): Check that status is in range.
4063 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4064 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4065 Accept and return EMACS_INT, not int, because callers can pass values
4067 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4068 (multibyte_chars_in_text, parse_str_as_multibyte)
4069 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
4070 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4071 (string_escape_byte8, Fget_byte):
4072 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4073 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4074 avoid mishandling large integers.
4075 * character.h: Adjust decls to match defn changes elsewhere.
4076 * charset.c (load_charset_map_from_file, find_charsets_in_text)
4077 (Ffind_charset_region):
4078 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4079 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
4080 (load_charset_map_from_vector, Fdefine_charset_internal):
4081 Don't assume fixnum fits in int.
4082 (load_charset_map_from_vector, Fmap_charset_chars):
4083 Remove now-unnecessary CHECK_NATNUMs.
4084 (Fdefine_charset_internal): Check ranges here, more carefully.
4085 Don't rely on undefined behavior with signed left shift overflow.
4086 Don't assume unsigned int fits into fixnum, or that fixnum fits
4087 into unsigned int. Don't require max_code to be a valid fixnum;
4088 that's not true for gb10830 4-byte on a 32-bit host. Allow
4089 invalid_code to be a cons, for the same reason. Require code_offset
4090 to be a character. Avoid int overflow if max_char is close
4092 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4093 this is intended anyway and avoids some undefined behavior.
4094 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4095 INDEX_TO_CODE_POINT, as that's what it expects.
4096 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4097 * charset.h (DECODE_CHAR): Return int, not unsigned;
4098 this is what was intended anyway, and it avoids undefined behavior.
4099 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4100 integer-overflow issues.
4101 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4102 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4103 where the argument is EMACS_INT, and this behavior is not intended.
4104 * chartab.c (Fmake_char_table, Fset_char_table_range)
4105 (uniprop_get_decoder, uniprop_get_encoder):
4106 Don't assume fixnum fits in int.
4107 * cmds.c (move_point): New function, that does the gist of
4108 Fforward_char and Fbackward_char, but does so while checking
4109 for integer overflow more accurately.
4110 (Fforward_char, Fbackward_char): Use it.
4111 (Fforward_line, Fend_of_line, internal_self_insert)
4112 (internal_self_insert):
4113 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4114 Fix a FIXME, by checking for integer overflow when calculating
4115 target_clm and actual_clm.
4116 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
4117 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

4853 2012-05-19 Ken Brown <kbrown@cornell.edu>
4855 * xfns.c (x_in_use): Remove `static' qualifier.
4856 * xterm.h (x_in_use): Declare.
4857 * xgselect.c: Include xterm.h.
4858 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4859 and `display_arg' (bug#9754).
4861 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4863 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4865 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4866 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4868 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4870 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4872 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4873 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4875 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4876 reference to image_cache->refcount.
4877 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4879 2012-05-17 Juri Linkov <juri@jurta.org>
4881 * search.c (Fword_search_regexp, Fword_search_backward)
4882 (Fword_search_forward, Fword_search_backward_lax)
4883 (Fword_search_forward_lax): Move functions to isearch.el
4884 (bug#10145, bug#11381).
4886 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4888 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4890 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4892 * lread.c (init_obarray): Declare Qt and Qnil as special.
4894 2012-05-14 Glenn Morris <rgm@gnu.org>
4896 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4897 Put "libexec" before "bin", for the sake of init_callproc_1.
4899 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4901 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4903 * unexaix.c: Port to more-recent AIX compilers.
4904 (report_error, report_error_1, make_hdr, copy_sym)
4905 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4906 Make arguments const char *, not char *, to avoid violations of C
4907 standard and to fix some AIX warnings reported by Gilles Pion.
4909 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4911 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4912 already have overlays loaded.
4913 (handle_single_display_spec): Before returning without displaying
4914 fringe bitmap, synchronize the bidi iterator with the main display
4915 iterator, by calling iterate_out_of_display_property.
4916 (iterate_out_of_display_property): Detect buffer iteration by
4917 testing that it->string is a Lisp string.
4918 (get_next_display_element): When the current object is exhausted,
4919 and there's something on it->stack, call set_iterator_to_next to
4920 proceed with what's on the stack, instead of returning zero.
4921 (set_iterator_to_next): If called at the end of a Lisp string,
4922 proceed to consider_string_end without incrementing string
4923 position. Don't increment display vector index past the end of
4924 the display vector. (Bug#11417)
4925 (pos_visible_p): Don't report a position visible when move_it_to
4926 stopped at the last line of window, which happens to be scanned
4927 backwards by the bidi iteration. (Bug#11464)
4929 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4931 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4932 and right-margin display specs even if the spec is invalid or we
4933 are on a TTY, and thus unable to display on the fringes.
4934 That's because the text with the property will not be displayed anyway,
4935 so we need to signal to the caller that this is a "replacing"
4936 display spec. This fixes display when the spec is invalid or we
4939 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4941 * unexaix.c (make_hdr): Fix typo in prototype.
4942 This bug broke the build on AIX. Problem reported by Gilles Pion.
4944 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4946 * keyboard.c (kbd_buffer_get_event): Read special events also in
4947 batch mode. (Bug#11415)
4949 2012-05-12 Glenn Morris <rgm@gnu.org>
4951 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4953 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4955 * lisp.mk (lisp): Add newcomment.elc.
4957 2012-05-12 Glenn Morris <rgm@gnu.org>
4959 * Makefile.in (MKDIR_P): New, set by configure.
4960 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4962 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4964 Remove unused function hourglass_started.
4965 * dispextern.h (hourglass_started):
4966 * w32fns.c (hourglass_started):
4967 * xdisp.c (hourglass_started): Remove.
4969 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4971 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4972 Update dependencies.
4974 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4976 * xgselect.c (xg_select): Put maxfds+1 into a var.
4977 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4979 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4981 2012-05-10 Dave Abrahams <dave@boostpro.com>
4983 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4984 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4986 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4988 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4989 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4990 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4991 Initialize xd_registered_buses.
4993 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4995 Untag more efficiently if USE_LSB_TAG.
4996 This is based on a proposal by YAMAMOTO Mitsuharu in
4997 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4998 For an admittedly artificial (nth 8000 longlist) benchmark on
4999 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5000 Emacs's overall text size by 1%.
5001 * lisp.h (XUNTAG): New macro.
5002 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5003 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5004 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5005 * eval.c (Fautoload):
5006 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5007 * frame.h (XFRAME): Use XUNTAG.
5009 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5010 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5011 Remove unportable assumptions about print widths of types like
5013 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5014 intptr_t when converting between pointer and integer, to avoid GCC
5015 warnings about wrong width.
5017 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5019 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5020 stack for each reader_thread, instead of defaulting to 8MB
5021 determined by the linker. This avoids failures in creating
5022 subprocesses on Windows 7, see the discussion in this thread:
5023 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5025 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5027 Fix up display of the *Minibuf-0* buffer in the mini window.
5028 * keyboard.c (read_char): Don't clear the echo area if there's no
5030 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5031 contents of *Minibuf-0*) if there's no message displayed in its stead.
5033 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5035 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5038 2012-05-06 Chong Yidong <cyd@gnu.org>
5040 * lisp.mk (lisp): Update.
5042 2012-05-05 Jim Meyering <meyering@redhat.com>
5044 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5046 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5048 * data.c (PUT_ERROR): New macro.
5049 (syms_of_data): Use it. Add new error type `user-error'.
5050 * undo.c (user_error): New function.
5051 (Fprimitive_undo): Use it.
5052 * print.c (print_error_message): Adjust print style for `user-error'.
5053 * keyboard.c (user_error): New function.
5054 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5056 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5058 Do not limit current-time-string to years 1000..9999.
5059 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5060 (Fcurrent_time_string): Support any year that is supported by the
5061 underlying localtime representation. Don't use asctime, as it
5062 has undefined behavior for years outside the range -999..9999.
5064 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5066 Fix race conditions involving setenv, gmtime, localtime, asctime.
5067 Without this fix, interrupts could mess up code that uses these
5068 nonreentrant functions, since setting TZ invalidates existing
5069 tm_zone or tzname values, and since most of these functions return
5070 pointers to static storage.
5071 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5072 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5073 Grow the critical sections to include not just invoking
5074 localtime/gmtime, but also accessing these functions' results
5075 including their tm_zone values if any, and any related TZ setting.
5076 (format_time_string): Last arg is now struct tm *, not struct tm **,
5077 so that the struct tm is saved in the critical section.
5078 All callers changed. Simplify allocation of initial buffer, partly
5079 motivated by the fact that memory allocation needs to be outside
5080 the critical section.
5082 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5084 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5085 with RESET_INTERVAL.
5087 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5088 Remove duplicated buffer name initialization.
5090 2012-05-02 Jim Meyering <jim@meyering.net>
5092 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5094 * xfns.c (x_window): Use xstrdup (Bug#11375).
5096 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5098 * xdisp.c (pos_visible_p): If already at a newline from the
5099 display string before the 'while' loop, don't walk back the glyphs
5100 from it3.glyph_row. Solves assertion violation when the display
5101 string begins with a newline (egg.el). (Bug#11367)
5103 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5105 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5108 2012-05-01 Glenn Morris <rgm@gnu.org>
5110 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5111 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5112 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5113 All were removed before 23.1.
5115 * dispnew.c: Remove HAVE_LIBNCURSES test;
5116 it is always true on relevant platforms.
5118 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5119 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5121 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5123 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5125 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5126 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5129 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5131 Do not avoid creating empty evaporating overlays (Bug#9642).
5132 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5133 That is, do not delete an evaporating overlay if it becomes
5134 empty after its bounds are adjusted to fit within its buffer.
5135 This fix caused other problems, and I'm reverting it until we get
5136 to the bottom of them.
5138 2012-04-27 Chong Yidong <cyd@gnu.org>
5140 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5142 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5144 * xdisp.c (pos_visible_p): If the window start position is beyond
5145 ZV, start the display from buffer beginning. Prevents assertion
5146 violation in init_iterator when the minibuffer window is scrolled
5149 * window.c (window_scroll_pixel_based): Likewise.
5151 2012-04-27 Chong Yidong <cyd@gnu.org>
5153 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5155 2012-04-27 Glenn Morris <rgm@gnu.org>
5157 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5158 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5160 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5162 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5163 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5165 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5167 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5168 display element, check also the underlying string or buffer
5169 character. (Bug#11341)
5171 * w32menu.c: Include w32heap.h.
5172 (add_menu_item): If the call to AppendMenuW (via
5173 unicode_append_menu) fails, disable Unicode menus only if we are
5174 running on Windows 9X/Me.
5176 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5178 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5179 (xgetint): Add missing shift for LSB tags.
5181 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5183 * keyboard.c (read_char): Don't wipe echo area for select window
5184 events: These might get delayed via `mouse-autoselect-window'
5187 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5189 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5190 manipulation of :loaded-from data.
5192 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5194 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5195 now a cons (bug#11311).
5197 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5199 Do not create empty overlays with the evaporate property (Bug#9642).
5200 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5201 if it becomes empty after its bounds are adjusted to fit within
5202 its buffer. Without this fix, in a nonempty buffer (let ((o
5203 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5204 yields an empty overlay that has the evaporate property, which is
5205 not supposed to happen.
5207 Fix minor GTK3 problems found by static checking.
5208 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5209 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5210 (struct _EmacsFixedClass, emacs_fixed_get_type):

5213 (emacs_fixed_class_init): Omit unused local.
5214 (emacs_fixed_child_type): Remove; unused.

5218 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5219 (EMACS_FIXED_GET_CLASS): Remove; unused.
5220 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5222 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5223 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5225 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5227 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5228 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5229 (__malloc_size_t, __malloc_ptrdiff_t):
5230 Remove. All uses removed, replaced by the definiens if needed,
5231 since we can assume C89 or better now.
5232 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5233 (protect_malloc_state, align, get_contiguous_space)
5234 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5240 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5241 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5242 Define using prototypes, not old style.
5243 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5244 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5245 (align): Don't assume that signed integer overflow wraps around.
5246 Omit unused local var.
5247 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5248 (_free_internal_nolock, memalign, mallochook, reallochook):
5249 Omit no-longer-needed casts.
5250 (valloc): Use getpagesize, not __getpagesize.
5251 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
5252 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5254 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5256 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
5258 Move functions from C to Lisp. Make non-blocking method calls
5259 the default. Implement further D-Bus standard interfaces.

5301 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>

5304 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
5305 Do not assume ptrdiff_t is the same width as 'int'.
5307 * alloc.c: Handle unusual debugging option combinations.
5308 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5309 since the two debugging options are incompatible.
5310 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5312 (mem_init, mem_insert, mem_insert_fixup):
5313 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5325 Use 'double' consistently rather than mixing 'float' and 'double'.
5327 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5329 * sysdep.c (list_system_processes, system_process_attributes):
5330 Add implementation for FreeBSD (Bug#5243).

5343 * print.c (print_preprocess): Only check print_depth if print-circle
5345 (print_object): Check for cycles even when print-circle is nil and
5346 print-gensym is t, but only check print_depth if print-circle is nil.
5348 2012-04-20 Chong Yidong <cyd@gnu.org>
5350 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5351 set the status to "failed" and ensure that sentinel is run.
5353 2012-04-20 Glenn Morris <rgm@gnu.org>

5364 row, return zero immediately.
5365 (try_cursor_movement): If inside continuation line, don't back up
5366 farther than the first row after the header line, if any.
5367 Don't consider the header-line row as "partially visible", even if
5368 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5370 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5384 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
5385 -Wunused-result, -Wunused-variable. This should go away once
5386 the Emacs and Gnulib regex code is merged.
5387 (xmalloc, xrealloc): Now static.
5389 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

5405 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5406 New extern decls, to avoid calling undeclared functions.
5407 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5408 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5409 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5410 (NEED_MEM_INSERT): New macro.
5411 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5412 Remove one incorrect comment and fix another.

5426 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5427 Remove decls. This fixes an "It stinks!".

5431 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5433 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5446 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5447 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5448 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5449 * s/netbsd.h, s/sol2-6.h:
5450 Remove definition of GC_MARK_STACK, since the default now works.
5451 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5452 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5453 no longer the default.
5454 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5456 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5458 * lread.c (lisp_file_lexically_bound_p):

5466 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5468 * nsterm.m (constrainFrameRect): Always constrain when there is only
5469 one screen (Bug#10962).

5479 2012-04-11 Daniel Colascione <dancol@dancol.org>
5481 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5482 against is gone. It's better to use vfork now so that when Cygwin
5483 gains a new, working vfork, we use it automatically (bug#10398).
5485 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5501 (handle_interrupt): Use it.
5503 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5505 * w32.c (w32_delayed_load): Record the full path of the library
5506 being loaded (bug#10424).
5508 2012-04-09 Glenn Morris <rgm@gnu.org>
5510 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5511 not just in the obarray, before snarfing them. (Bug#11036)
5513 * Makefile.in ($(leimdir)/leim-list.el):
5514 Pass EMACS rather than BUILT_EMACS.

5523 Add convenience `GNUTLS_LOG2i' macro.
5525 * gnutls.c (gnutls_log_function2i): Convenience log function.
5526 (emacs_gnutls_read): Use new log functions,
5527 `gnutls_handshakes_tried' process member, and

5529 attempts per process (connection).
5531 2012-04-09 Chong Yidong <cyd@gnu.org>

5538 * minibuf.c (Fread_variable): Callers changed.
5540 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5542 * xdisp.c (set_cursor_from_row): If the display string appears in
5543 the buffer at position that is closer to point than the position
5544 after the display string, display the cursor on the first glyph of
5545 the display string. Fixes cursor display when a 'display' text
5546 property immediately follows invisible text. (Bug#11094)
5548 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5550 composite.c: use 'double' consistently
5551 * composite.c (get_composition_id): Use 'double' consistently
5552 instead of converting 'float' to 'double' and vice versa; this is
5553 easier to understand and avoids a GCC warning.
5555 2012-04-09 Glenn Morris <rgm@gnu.org>
5557 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5558 preparation for dumping it with emacs. (Bug#4789)

5580 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5581 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5582 objects, as mark_maybe_pointer will catch them otherwise.
5583 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5584 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

5588 Fix typo that broke non-Windows builds.
5589 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5600 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5601 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5602 [!WINDOWSNT]: New macros.
5603 (init_libxml2_functions, libxml2_loaded_p): New functions.
5604 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5605 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5606 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5607 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5609 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5610 Call init_libxml2_functions before calling libxml2 functions.
5611 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5613 * emacs.c: Don't include libxml/parser.h.
5614 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5615 xmlCleanupParser directly.
5617 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5619 2012-04-07 Eli Zaretskii <eliz@gnu.org>

5627 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5628 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5629 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5630 macros related to unification of CJK characters. For the details,
5631 see the discussion following the message here:
5632 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5634 2012-04-04 Chong Yidong <cyd@gnu.org>
5636 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5638 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5640 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

5648 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5650 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5651 position we get to after a call to move_it_to fails the
5652 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5653 only if we wind up in a string from display property. (Bug#11063)
5655 * window.c (Fdelete_other_windows_internal): Invalidate the row
5656 and column information about mouse highlight, so that redisplay
5657 restores it after reallocating the glyph matrices. (Bug#7464)
5659 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5660 string comes from a `display' text property, use the buffer
5661 position of that property as if we actually saw that position in
5663 (move_it_by_lines): Remove the assertion that
5664 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5665 violated when there's a before-string at the beginning of a line.
5668 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5670 * xdisp.c (append_space_for_newline): If the default face was
5671 remapped, use the remapped face for the appended newline.
5672 (extend_face_to_end_of_line): Use the remapped default face for
5673 extending the face to the end of the line.
5674 (display_line): Call extend_face_to_end_of_line when the default
5675 face was remapped. (Bug#11068)
5677 2012-03-29 Eli Zaretskii <eliz@gnu.org>

5699 handle-select-window too (Bug#8996).
5701 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5703 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5705 2012-03-25 Kenichi Handa <handa@m17n.org>
5707 * dispextern.h (struct glyph): Change the bit length of
5708 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5710 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5712 * s/ms-w32.h (tzname): Include time.h before redirecting to
5713 _tzname. Fixes the MSVC build. (Bug#9960)

5717 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5720 * xterm.c (XTread_socket): Only modify handling_signal if

5723 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5725 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5726 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5727 when fetching a multibyte character consumes more bytes than
5728 CHAR_BYTES returns, due to unification of CJK characters in
5729 string_char. (Bug#11073)
5731 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5733 * process.c (wait_reading_process_output): Handle pty disconnect
5734 by refraining from sending oneself a SIGCHLD (bug#10933).

5745 2012-03-21 Chong Yidong <cyd@gnu.org>
5747 * xfaces.c (Vface_remapping_alist): Doc fix.
5749 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5751 * w32proc.c (Fw32_set_console_codepage)
5752 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5763 it fit in a valid range (Bug#11003).
5765 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5767 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5768 that is not from display property, accept the row as a "cursor
5769 row" if one of the string's character has a non-nil `cursor'
5770 property. Fixes cursor positioning when there are newlines in
5771 overlay strings, e.g. in icomplete.el. (Bug#11035)
5773 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5775 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5777 2012-03-12 Chong Yidong <cyd@gnu.org>

5803 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5804 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5807 2012-03-03 Glenn Morris <rgm@gnu.org>
5809 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

5822 * buffer.c (buffer-list-update-hook): Doc fix.
5824 2012-02-29 Eli Zaretskii <eliz@gnu.org>

5827 push_it before setting up the iterator for the first overlay
5828 string, even if we have an empty string loaded.
5829 (next_overlay_string): If there's an empty string on the iterator
5830 stack, pop the stack. (Bug#10903)
5832 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5834 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5835 Suggested by Stefan Monnier in
5836 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5837 * alloc.c (widen_to_Lisp_Object): New static function.
5838 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5839 and widening them to Lisp_Objects. This would work even if
5840 USE_LSB_TAG is defined and wide integers are used, which might
5841 happen in a future version of Emacs.
5843 2012-02-25 Chong Yidong <cyd@gnu.org>
5845 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

5860 call when setting menu-bar-lines and tool-bar-lines parameters.
5861 (unwind_create_frame_1): New helper function.
5863 * window.c (inhibit_window_configuration_change_hook): New var.
5864 (run_window_configuration_change_hook): Obey it.
5865 (syms_of_window): Initialize it.
5867 2012-02-22 Chong Yidong <cyd@gnu.org>
5869 * xterm.c (x_draw_image_relief): Add missing type check for

5882 when computing $valmask.
5884 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5885 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5886 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5887 It's useless in that case, and it can cause problems on hosts
5888 that allocate halves of EMACS_INT values separately.
5889 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5890 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5891 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5892 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5893 it avoids undefined behavior on hosts where shifting right by more
5894 than the word width has undefined behavior.
5896 2012-02-19 Chong Yidong <cyd@gnu.org>
5898 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5899 (Funhandled_file_name_directory, Ffile_name_as_directory)

5918 2012-02-15 Chong Yidong <cyd@gnu.org>
5920 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5921 marked as special. Also, starting docstrings with * is obsolete.

5936 2012-02-12 Chong Yidong <cyd@gnu.org>
5938 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5939 as that creates a dangerous corner case.
5941 * window.c (Fdelete_window_internal): Invalidate the mouse
5942 highlight (Bug#9904).
5944 2012-02-12 Glenn Morris <rgm@gnu.org>

5950 (Fx_disown_selection_internal, Fx_selection_exists_p)
5951 (Fx_selection_owner_p, Fx_get_selection_internal):
5952 Sync docs and argument specs with the xselect.c versions.

5974 2012-02-07 Chong Yidong <cyd@gnu.org>
5976 * buffer.c (Fbuffer_local_variables)
5977 (buffer_lisp_local_variables): Handle unbound vars correctly;
5978 don't let Qunbound leak into Lisp.
5980 2012-02-07 Glenn Morris <rgm@gnu.org>
5982 * image.c (Fimagemagick_types): Doc fix.
5984 * image.c (imagemagick-render-type): Change it from a lisp object

6017 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
6019 Handle overflow when computing char display width (Bug#9496).
6020 * character.c (char_width): Return EMACS_INT, not int.
6021 (char_width, c_string_width): Check for overflow when
6022 computing the width; this is possible now that individual
6023 characters can have unbounded width. Problem introduced
6024 by merge from Emacs 23 on 2012-01-19.
6026 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

6166 (Fmake_directory_internal): Use it.
6167 (do_auto_save_make_dir): Set it, instead of invoking chmod after

6169 too-generous permissions to the directory.
6170 (do_auto_save_eh): Clear it.
6171 (Fdo_auto_save): Catch all errors, not just file errors, so

6678 is set, removing the need for VIRT_ADDRESS_VARIES.

6682 to 4 (xorl, subq, cmpq, setbe).
6683 * alloc.c (pure): Always extern now, since that's the
6684 VIRT_ADDR_VARIES behavior.

6686 consistency with the new puresize.h.
6687 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6694 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6695 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6696 behave as if the cursor position were at the window margin.
6698 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6699 and the cursor position is out of bounds, behave as if the cursor
6700 position were at the window margin. (Bug#10075)
6702 2011-11-18 Chong Yidong <cyd@gnu.org>
6704 * window.c (Fwindow_combination_limit): Make first argument

6726 compute_line_metrics.
6727 (compute_line_metrics): Call row_hash, instead of computing the
6730 * dispnew.c (verify_row_hash): Call row_hash for computing the
6731 hash code of a row, instead of duplicating code from xdisp.c.
6733 * dispextern.h (row_hash): Add prototype.
6735 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6737 * frame.c (delete_frame): Don't delete the terminal when the last

6762 (recombine_windows, make_parent_window, make_window)
6763 (Fsplit_window_internal, saved_window)
6764 (Fset_window_configuration, save_window_save): Rename all
6765 occurrences of window_nest to window_combination_limit.
6767 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6769 * image.c (imagemagick_load_image): Fix typo.
6771 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6773 * xdisp.c (display_line): Move the call to
6774 highlight_trailing_whitespace before the call to

6926 (static_offset_intervals): Remove.
6927 (offset_intervals): Rewrite using the old contents of
6928 static_offset_intervals. The old version didn't conform to C99

6952 (Fwindow_vscroll): Doc fix.

7242 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7243 * editfns.c: Rewrite current-time-zone so that it invokes
7244 the equivalent of (format-time-string "%Z") to get the time zone name.
7245 This fixes a bug when the time zone name contains characters that
7246 need converting from the system time locale to Emacs internal format.
7247 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7248 that patch fixed format-time-string to do the conversion, but
7249 I forgot to fix current-time-zone.
7250 (format_time_string): New function, containing most of
7251 what Fformat_time_string used to contain.
7252 (Fformat_time_string): Rewrite in terms of format_time_string.
7253 This doesn't change this function's behavior.
7254 (current-time-zone): Rewrite to use format_time_string.
7255 This fixes the bug reported by Michael Schierl in
7256 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7257 Jason Rumney's 2007-06-07 change worked around this bug, but
7259 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7261 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7263 * xdisp.c (start_display): If the character at POS is displayed
7264 via a display vector, reset IT->current.dpvec_index to zero.
7265 (try_window_reusing_current_matrix): If a line ends in a display
7266 vector or the next line starts in a display vector, continue
7267 redrawing the window even though the character position of
7268 start_row was reached.
7271 2011-10-18 Chong Yidong <cyd@gnu.org>
7273 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7274 with nobreak-char-display too.
7276 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7278 Fix part 3 of bug#9771.
7279 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7280 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7281 non-neutral characters if the current character is a paragraph
7282 separator (a.k.a. Newline). This avoids running the same
7283 expensive loop twice, once when we consume the preceding newline
7284 and the other time when the line actually needs to be displayed.
7285 Avoid the loop when we see neutrals on the base embedding level
7286 following a character whose directionality is the same as the
7287 paragraph's. This avoids running the expensive loop when a line
7288 ends in a long sequence of neutrals, like control characters.
7289 Add assertion against STRONG_AL type. Slightly rearrange code
7290 that determines the type of a neutral given the first non-neutral
7292 (bidi_level_of_next_char): Set next_en_pos to zero when
7293 invalidating its info.
7295 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7297 * xdisp.c (push_display_prop): Determine whether to record string
7298 or buffer position by IT->string, not by IT->method. Allow
7299 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7300 (move_it_vertically_backward): Don't look for character position
7301 immediately after the newline when in a continuation line.
7304 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7306 * window.c (coordinates_in_window): Rewrite and delabelize
7307 vertical border check. (Bug#5357) (Bug#9618)
7309 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7311 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7312 errors in XSetWindowBorder (bug#9310).
7314 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7316 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7317 avoid crash when xmalloc overrun checking is enabled.
7319 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7321 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7322 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7323 cursor motion with <left> and <right> arrow keys.
7325 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7326 some callers set that themselves.
7328 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7330 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7331 display string and the previous row comes from the same string and
7332 is empty. (Bug#9739) (Bug#9738)
7334 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7336 * doc.c (get_doc_string): Encode file name (bug#9735).
7338 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7340 * bidi.c (bidi_level_of_next_char):
7341 * xdisp.c (get_visually_first_element): Remove old incorrect
7342 comments regarding the Unicode Line Separator character.
7344 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7346 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7348 * alloc.c (Fgc_status): Do not access beyond zombies array
7349 boundary if nzombies > MAX_ZOMBIES.
7350 * alloc.c (dump_zombies): Add missing format specifier.
7352 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7354 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7355 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7357 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7358 Some packages use them to denote characters with modifiers.
7360 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7362 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7363 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7364 matching a pp-number. Rename parameter var to var1.
7366 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7368 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7370 2011-10-08 Glenn Morris <rgm@gnu.org>
7372 * callint.c (Fcall_interactively): Give a more explicit error for the
7373 'c' case with a non-character input. (Bug#8479)
7375 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7377 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7379 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7380 lines that are hscrolled on the left.
7382 * dispnew.c (buffer_posn_from_coords): Account for a possible
7383 presence of header-line. (Bug#4426)
7385 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7387 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7388 Don't advertise functionality which we discourage or doesn't work.
7390 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7392 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7393 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7394 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7395 this makes Emacs dump core during garbage collection on rare
7396 occasions. sizeof is obviously inferior to offsetof here, so
7397 stick with offsetof.
7398 (GC_POINTER_ALIGNMENT): New macro.
7399 (mark_memory): Omit 3rd (offset) arg; caller changed.
7400 Don't assume EMACS_INT alignment is the same as pointer alignment.
7402 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7404 * keyboard.c (read_key_sequence_remapped): New var.
7405 (read_key_sequence): Compute remapping in the right buffer.
7406 (command_loop_1): Use read_key_sequence's remapping directly.
7408 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7410 * dired.c (file_name_completion): Don't expand file name.
7411 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7412 before checking file name handler.
7414 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7415 they've been requested explicitly (bug#9591).
7417 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7419 * keymap.c (Fsingle_key_description): Use make_specified_string
7420 instead of build_string to build string from push_key_description.
7423 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7425 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7426 This fixes a Y2038 bug on 64-bit hosts.
7427 * buffer.c (reset_buffer):
7428 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7429 (Fclear_buffer_auto_save_failure):
7430 Use 0, not -1, to represent an unset failure time, since time_t
7431 might not be signed.
7433 Remove dependency on glibc malloc internals.
7434 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7435 Move back here from lisp.h, but with their new implementations.
7436 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7437 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7438 * charset.c (charset_table_init): New static var.
7439 (syms_of_charset): Use it instead of xmalloc. This removes a
7440 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7441 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7442 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7443 Move back to alloc.c.
7444 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7445 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7447 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7449 * nsterm.m (windowDidResize): Call x_set_window_size only when
7450 ns_in_resize is true. Otherwise set pixelwidth/height and
7451 call change_frame_size (Bug#9628).
7453 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7455 Port --enable-checking=all to Fedora 14 x86-64.
7456 * charset.c (syms_of_charset): Also account for glibc malloc's
7457 internal overhead when calculating the initial malloc maximum.
7459 Port --enable-checking=all to Fedora 14 x86.
7460 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7462 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7463 (overrun_check_realloc, overrun_check_free):
7464 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7465 That way, xmalloc returns a properly-aligned pointer even if
7466 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7467 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7468 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7469 into account when calculating the initial malloc maximum.
7470 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7471 Move here from alloc.c, so that charset.c can use it too.
7472 Properly align; the old code wasn't right for common 32-bit hosts
7473 when configured with --enable-checking=all.
7474 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7475 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7477 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7479 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7482 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7484 * xdisp.c (compute_display_string_end): If there's no display
7485 string at CHARPOS, return -1.
7487 * bidi.c (bidi_fetch_char): When compute_display_string_end
7488 returns a negative value, treat the character as a normal
7489 character not covered by a display string. (Bug#9624)
7491 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7493 * lread.c (Fread_from_string): Fix typo in docstring.
7495 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7497 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7498 newline, reseat the iterator instead of bidi-iterating there one
7499 character at a time. (Bug#9610)
7500 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7501 TO_CHARPOS if the bidi iterator is at base embedding level.
7503 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7505 * lread.c (readevalloop): Use correct code for NBSP.
7506 (read1): Likewise. (Bug#9608)
7508 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7510 * dbusbind.c (Fdbus_register_signal): When service is not
7511 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7513 2011-09-25 Glenn Morris <rgm@gnu.org>
7515 * buffer.c (truncate-lines): Doc fix.
7517 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7519 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7520 (Fset_window_next_buffers): Doc fix.
7522 2011-09-24 Glenn Morris <rgm@gnu.org>
7524 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7526 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7528 Fix minor problems found by static checking.
7529 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7530 * indent.c (Fvertical_motion): Fix == vs = typo.
7532 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7534 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7535 Default value is now t. Doc fix.
7537 * indent.c (Fvertical_motion): Compute and apply the overshoot
7538 logic when moving up, not only when moving down. Fix the
7539 confusing name and values of the it_overshoot_expected variable;
7540 logic changes accordingly. (Bug#9254) (Bug#9549)
7542 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7543 CHARPOS is covered by a display string which includes newlines.
7544 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7545 is covered by a display string with embedded newlines.
7547 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7549 * dbusbind.c (Fdbus_register_signal): Add match rule to
7550 Vdbus_registered_objects_table. (Bug#9581)
7551 (Fdbus_register_method, Vdbus_registered_objects_table):
7554 2011-09-24 Jim Meyering <meyering@redhat.com>
7556 do not ignore write error for any output size
7557 The previous change was incomplete.
7558 While it makes emacs --batch detect the vast majority of stdout
7559 write failures, errors were still ignored whenever the output size is
7560 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7561 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7562 && echo FAIL: ignored write error
7563 FAIL: ignored write error
7564 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7565 && echo FAIL: ignored write error
7566 FAIL: ignored write error
7567 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7569 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

7572 non-successfully if a write error occurred on stdout. (Bug#9574)
7574 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7576 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7579 * dispextern.h (struct it): Update the comment documenting what
7582 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7584 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7585 a display string, extend search for cursor position to end of row.
7586 (find_row_edges): If the row ends in a newline from a display
7587 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7588 Handle the case of a display string with multiple newlines.
7589 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7590 non-empty line. Fixes confusing cursor motion with arrow keys at
7591 the beginning of a line that starts with whitespace.

7600 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7603 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7605 * xdisp.c (display_line): Record maximum and minimum buffer
7606 positions even if no glyphs were produced (e.g., by a zero-width
7607 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7608 buffer positions that will be removed from the glyph row because
7610 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7611 column is beyond frame width: don't subtract 1 "pixel" when
7612 computing width of the stretch.
7613 (reseat_at_next_visible_line_start): Undo the change made on
7614 2011-09-17 that saved paragraph information and restored it after
7615 the call to `reseat'. (Bug#9545)
7617 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7619 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7620 and turn window cursor on if cleared (Bug#9415).

7633 Fix minor problem found by static checking.
7634 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7635 initialized, to pacify gcc -Wuninitialized.
7637 * fileio.c: Report proper errno when syscall falls.
7638 (Finsert_file_contents): Save and restore errno,
7639 so that report_file_error outputs the correct diagnostic.
7640 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7642 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7644 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7646 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7648 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7649 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7651 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7653 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7654 about the current paragraph and restore it after the call to reseat.
7656 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7657 (bidi_find_paragraph_start): Search back for paragraph beginning
7658 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7659 (bidi_move_to_visually_next): Only trigger paragraph-related
7660 computations when the last character is a newline or at EOB, not
7661 just any NEUTRAL_B. (Bug#9470)
7663 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7664 truncated lines if point is covered by a display string. (Bug#9524)
7666 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7668 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7669 (cons_to_x_long): New function.
7670 (lisp_data_to_selection_data): Use it. Correct the test for
7671 short-versus-long data; it was negated. Break out of vector
7672 loop, for efficiency, when a long datum is discovered.
7674 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7676 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7678 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7680 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

7704 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7705 This occurs when processing a multibyte format.
7706 Problem reported by Wolfgang Jenker.
7708 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7710 * xdisp.c (try_cursor_movement): Only check for exact match if
7711 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7713 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7715 Remove unused external symbols.
7716 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7717 * xdisp.c (calc_pixel_width_or_height): Now static.
7718 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7719 * indent.c (check_display_width):
7720 * w32term.c: Fix comment to match code.
7721 * xterm.c, xterm.h (x_catching_errors): Remove.
7723 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7725 * xselect.c: Use signed conversions more consistently (Bug#9498).
7726 (selection_data_to_lisp_data): Assume incoming selection data are
7727 signed integers, not unsigned. This is to be consistent with
7728 outgoing selection data, which was modified to use signed integers
7729 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7730 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7731 expects long, not unsigned long.
7733 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7735 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7736 computation of loop end. Reported by Johan Bockgård
7739 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7741 * frame.c (Fother_visible_frames_p): Function deleted.
7743 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7745 * indent.c (compute_motion): Process display vector front to back
7746 rather than the other way around. (Bug#2496)
7748 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7750 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7752 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7754 * minibuf.c (Fread_from_minibuffer): Doc fix.
7756 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7758 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7759 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7761 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7763 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7764 value for non-existent files.
7766 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7768 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7769 set its "size" to -1. This will set the modtime_size field of
7770 the corresponding buffer to -1, which is what
7771 verify-visited-file-modtime expects for files that do not exist.
7774 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7776 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7778 * lisp.h: ... from here. push_key_description is no longer
7779 defined in keyboard.c, so its declaration should not be in
7780 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7781 logically belongs with push_key_description.
7783 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7785 * buffer.h: Include <sys/types.h> instead of <time.h>.
7786 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7787 Problem reported by Herbert J. Skuhra.
7789 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7791 * xml.c (parse_region): Make the parsing work for
7792 non-comment-starting XML files again (bug#9144).
7794 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7796 * image.c (gif_load): Fix calculation of bottom and right corner.
7799 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7801 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7802 redisplay in small windows.
7804 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7806 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7808 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7810 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7811 Operate on live windows only.
7813 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7815 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7817 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7819 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7820 only under bidi iteration.
7822 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7824 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7826 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7828 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7829 Without this fix, the command to link temacs failed due to an
7830 undefined symbol __builtin_isnan. This is because
7831 /usr/include/iso/math_c99.h #defines isnan(x) to
7832 __builtin_isnan(x), but the bundled gcc, which identifies itself
7833 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7835 * floatfns.c (isnan): #undef, and then #define to a clone of
7837 (Fisnan): Always define, since it's always available now.
7838 (syms_of_floatfns): Always define isnan at the Lisp level.
7840 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7842 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7844 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7846 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7847 The previous code assumed that file offsets (off_t values) fit in
7848 EMACS_INT variables, which is not true on typical 32-bit hosts.
7849 The code messed up by falsely reporting buffer overflow in cases
7850 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7851 when "big" contains more than 2**29 bytes, even though this
7852 inserts just one byte and does not overflow the buffer.
7853 (Finsert_file_contents): Store file offsets as off_t
7854 values, not as EMACS_INT values. Check for overflow when
7855 converting between EMACS_INT and off_t. When checking for
7856 buffer overflow or for overlap, take the offsets into account.
7857 Don't use EMACS_INT for small values where int suffices.
7858 When checking for overlap, fix a typo: ZV was used where
7859 ZV_BYTE was intended.
7860 (Fwrite_region): Don't assume off_t fits into 'long'.
7861 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7863 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7865 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7867 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7869 sprintf-related integer and memory overflow issues (Bug#9412).
7871 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7872 (esprintf, exprintf, evxprintf): New functions.
7873 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7874 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7875 (modify_event_symbol): Do not assume that the length of
7876 name_alist_or_stem is safe to alloca and fits in int.
7877 (Fexecute_extended_command): Likewise for function name and binding.
7878 (Frecursion_depth): Wrap around reliably on integer overflow.
7879 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7880 since some callers pass EMACS_INT values.
7881 (Fsingle_key_description): Don't crash if symbol name contains more
7882 than MAX_ALLOCA bytes.
7883 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7884 (get_minibuffer): Arg is now EMACS_INT, not int.
7885 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7886 (esprintf, exprintf, evxprintf): New decls.
7887 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7889 * dbusbind.c (signature_cat): New function.
7890 (xd_signature, Fdbus_register_signal):
7891 Do not overrun buffer; instead, report string overflow.
7893 * dispnew.c (add_window_display_history): Don't overrun buffer.
7894 Truncate instead; this is OK since it's just a log.
7896 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7897 even if the time zone offset is outlandishly large.
7898 Don't mishandle offset == INT_MIN.
7900 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7901 when creating daemon; the previous buffer-overflow check was incorrect.
7903 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7904 which has the guts of the old verror function.
7906 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7907 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7909 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7910 (font_unparse_xlfd): Don't blindly alloca long strings.
7911 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7912 fits in int, when using sprintf. Use single snprintf to count
7913 length of string rather than counting it via multiple sprintfs;
7914 that's simpler and more reliable.
7915 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7916 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7917 sprintf, in case result does not fit in int.
7919 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7920 (fontset_from_font): Print it.
7922 * frame.c (tty_frame_count): Now printmax_t, not int.
7923 (make_terminal_frame, set_term_frame_name): Print it.
7924 (x_report_frame_params): In X, window IDs are unsigned long,
7925 not signed long, so print them as unsigned.
7926 (validate_x_resource_name): Check for implausibly long names,
7927 and don't assume name length fits in 'int'.
7928 (x_get_resource_string): Don't blindly alloca invocation name;
7929 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7932 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7933 (xg_check_special_colors, xg_set_geometry):
7934 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7936 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7937 Use esprintf, not sprintf, in case result does not fit in int.
7939 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7940 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7941 it as a large positive number.
7942 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7943 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7945 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7946 in case result does not fit in int.
7948 * print.c (float_to_string): Detect width overflow more reliably.
7949 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7950 buffer overrun. Don't assume list length fits in 'int'. Treat
7951 print length of 0 as 0, not as infinity; to be consistent with other
7952 uses of print length in this function. Don't overflow print length
7953 index. Don't assume hash table size fits in 'long', or that
7954 vectorlike size fits in 'unsigned long'.
7956 * process.c (make_process): Use printmax_t, not int, to format
7957 process-name gensyms.
7959 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7961 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7962 to avoid potential buffer overrun.
7964 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7965 if X resource line is longer than 512 bytes.
7967 * xfns.c (x_window): Make sprintf buffer a bit bigger
7968 to avoid potential buffer overrun.
7970 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7972 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7974 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7976 Integer overflow fixes for scrolling, etc.
7977 Without these, Emacs silently mishandles large integers sometimes.
7978 For example, "C-u 4294967297 M-x recenter" was treated as if
7979 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7981 * xdisp.c (try_window_id): Check Emacs fixnum range before
7982 converting to 'int'.
7984 * window.c (window_scroll_line_based, Frecenter):
7985 Check that an Emacs fixnum is in range before assigning it to 'int'.
7986 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7987 values converted from Emacs fixnums.
7988 (Frecenter): Don't wrap around a line count if it is out of 'int'
7989 range; instead, treat it as an extreme value.
7990 (Fset_window_configuration, compare_window_configurations):
7991 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7993 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7994 that can exceed INT_MAX. Check that EMACS_INT value is in range
7995 before assigning it to the (possibly-narrower) index.
7996 (match_limit): Don't assume that a fixnum can fit in 'int'.
7998 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8001 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8002 (Fvertical_motion): Don't wrap around LINES values that don't fit
8003 in 'int'. Instead, treat them as extreme values. This is good
8004 enough for windows, which can't have more than INT_MAX lines anyway.
8006 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8008 * Require libxml/parser.h to avoid compilation warning.
8010 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8012 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8013 since this reportedly can destroy thread storage.
8015 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8017 * syntax.c (find_defun_start): Update all cache variables if
8018 exiting early (Bug#9401).
8020 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8022 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8024 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8025 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8026 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8028 * term.c (tty_append_glyph): New function.
8029 (produce_stretch_glyph): Static function and its prototype deleted.
8031 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8034 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8036 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8037 when checking :margin (Bug#9390).
8038 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8039 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8040 so that the name doesn't mislead. All uses changed.
8042 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8044 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8047 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8049 * xdisp.c (move_it_to): Don't bail out early when reaching
8050 position beyond to_charpos, if we are scanning backwards.
8051 (move_it_vertically_backward): When DY == 0, make sure we get to
8052 the first character in the line after the newline.
8054 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8056 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8057 (ccl_driver): Do not generate an out-of-range pointer.
8058 (Fccl_execute_on_string): Remove unnecessary check for
8059 integer overflow, noted by Stefan Monnier in
8060 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8061 Remove a FIXME that didn't need fixing.
8062 Simplify the newly-introduced buffer reallocation code.
8064 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8066 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8068 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8070 Integer and memory overflow issues (Bug#9196).
8072 * doc.c (get_doc_string): Rework so that
8073 get_doc_string_buffer_size is the actual buffer size, rather than
8074 being 1 less than the actual buffer size; this makes xpalloc more
8077 * image.c (x_allocate_bitmap_record, cache_image):
8078 * xselect.c (Fx_register_dnd_atom):
8079 Simplify previous changes by using xpalloc.
8081 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8082 since either will do and ptrdiff_t is convenient with xpalloc.
8084 * charset.c (charset_table_size)
8085 (struct charset_sort_data.priority): Now ptrdiff_t.
8086 (charset_compare): Don't overflow if priorities differ greatly.
8087 (Fsort_charsets): Don't assume list length fits in int.
8088 Check for size-calculation overflow when allocating sort data.
8089 (syms_of_charset): Allocate an initial charset table that is
8090 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8092 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8094 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8095 The actual value is always <= INT_MAX, and leaving it unsigned made
8096 overflow checking harder.
8098 * dispextern.h (struct glyph_matrix.rows_allocated)
8099 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8100 with xpalloc. The values are still always <= INT_MAX.
8102 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8104 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8105 (SAFE_NALLOCA): New macro.
8107 * region-cache.c (struct boundary.pos, find_cache_boundary)
8108 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8109 (set_cache_region, invalidate_region_cache)
8110 (revalidate_region_cache, know_region_cache, region_cache_forward)
8111 (region_cache_backward, pp_cache):
8112 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8113 so that ptrdiff_t * can be passed to xpalloc.
8114 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8115 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8116 (pp_cache): Don't assume cache_len fits in int.
8117 * region-cache.h: Adjust extern decls to match.
8119 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8120 EMACS_INT, since either will do, for xpalloc.
8122 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8123 (xnmalloc, xnrealloc, xpalloc): New functions.
8125 * bidi.c (bidi_shelve_header_size): New constant.
8126 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8127 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8129 * bidi.c (bidi_cache_shrink):
8130 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8132 Don't update size of array until after memory allocation succeeds,
8133 because xmalloc/xrealloc may not return.
8134 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8135 now that we have proper integer overflow checking.
8136 (record_overlay_string, overlay_strings): Catch overflows when
8137 calculating size of overlay_str_buf.
8139 * callproc.c (Fcall_process): Check for size overflow when
8140 calculating size of args2.
8141 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8142 Normally we prefer signed values, but sticking with ptrdiff_t would
8143 require adding more-complicated checks.
8145 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8146 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8147 Redo buffer-overflow calculations to avoid integer overflow.
8148 Add a FIXME comment where memory seems to be over-allocated.
8150 * character.c (Fstring): Check for size-calculation overflow.
8152 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8153 unnecessary integer overflow. Check for size overflow.
8154 (encode_coding_object): Don't update size until xmalloc succeeds.
8156 * composite.c (get_composition_id): Check for overflow in glyph
8157 length calculations.
8159 Integer and memory overflow fixes for display code.
8160 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8161 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8162 (scrolling_window): Check for overflow in size calculations.
8163 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8164 Don't assume glyph table len fits in int.
8165 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8166 (row_table_size): Now ptrdiff_t, not int.
8167 (scrolling_window): Avoid overflow in size calculations.
8168 Don't update size until allocation succeeds.
8169 * fns.c (concat): Check for overflow in size calculations.
8170 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8171 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8172 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8174 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8175 (get_doc_string): Check for size calculation overflow.
8176 Don't update size until allocation succeeds.
8177 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8178 EMACS_INT, where ptrdiff_t will do.
8179 (Fsubstitute_command_keys): Check for string overflow.
8181 * editfns.c (set_time_zone_rule): Don't assume environment length
8183 (message_length): Now ptrdiff_t, not int.

8185 Don't assume message length fits in int.
8186 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8188 * emacs.c (main): Do not reallocate argv, since there is a null at
8189 the end that can be overwritten, and this way there's no need to
8190 worry about size-calculation overflow.
8191 (sort_args): Check for size-calculation overflow.
8193 * eval.c (init_eval_once, grow_specpdl): Don't update size until

8269 (Fset_match_data): Don't assume list lengths fit in 'int'.
8271 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,

8303 Check for size calculation overflow.
8304 (cache_face): Treat size calculation overflows as if they were
8305 memory exhaustion (the usual treatment), rather than aborting.
8307 * xfns.c (x_encode_text, x_set_name_internal)
8308 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8309 sizes, since they can exceed INT_MAX in size. Check for size

8313 (xg_select): Check for size calculation overflow.
8314 Don't update size until alloc done.
8316 * xrdb.c (get_environ_db): Don't assume path length fits in int,

8319 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8320 (X_LONG_MIN): New macros.
8321 Use them to make the following changes clearer.
8322 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8323 This change doesn't affect the value now, but it may help remind
8324 future maintainers not to raise the value too much later.
8325 (SELECTION_QUANTUM): Remove, replacing with ...
8326 (selection_quantum): ... new function, which avoids overflow.
8328 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8329 assumption that selection length fits in 'int'.

8337 Redo calculations to avoid overflow.
8338 (x_reply_selection_request): When sending hint, ceiling it at

8342 (lisp_data_to_selection_data, x_property_data_to_lisp):
8343 Check for size-calculation overflow.

8346 Don't store size until memory allocation succeeds.
8347 (x_get_window_property): Plug memory leak on memory exhaustion.
8348 Don't double-block input; malloc is safe here. Don't assume 2**34
8349 - 4 fits in unsigned long. Add an xassert to check
8350 XGetWindowProperty overflow. Be more careful about overflow
8351 calculations, and distinguish size from memory overflow better.

8357 in the range -65535 through -1 fit in an X unsigned short.
8358 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8359 result parameters unless successful. Rely on cons_to_unsigned
8360 to report problems with elements; the old code wasn't right anyway.
8361 (x_check_property_data): Check for int overflow; we cannot use
8362 a wider type due to X limits.
8363 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8395 * lisp.h (hash_lookup, hash_put):
8396 * minibuf.c (Ftest_completion):
8397 Use ptrdiff_t for hash table indexes, not int (which is too
8398 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8399 32-bit --with-wide-int hosts).
8401 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8402 Add a FIXME comment about memory leaks.

8409 Use sanitize_char_width to avoid undefined and/or bad behavior
8410 with outlandish widths.
8411 * character.h (sanitize_tab_width): Rename from sanitize_width,
8412 now that we have two such functions. All uses changed.
8413 (sanitize_char_width): New inline function.

8432 (x_send_scroll_bar_event): Likewise. Check that the size does not
8433 exceed limits imposed by XClientMessageEvent, as well as the usual
8434 ptrdiff_t and size_t limits.
8436 * keyboard.c: Overflow, signedness and related fixes.
8437 (make_lispy_movement): Use same integer type in forward decl
8438 that is used in the definition.
8439 (read_key_sequence, keyremap_step):
8440 Change bufsize argument back to int, undoing my 2011-03-30 change.
8441 We prefer signed types, and int is wide enough here.
8442 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8443 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8444 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8445 length, not size_t. Use ptrdiff_t for index, not int.
8446 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8447 possibility of integer overflow.

8474 (png_load, gif_load, svg_load_image):
8475 Prefer int to unsigned where either will do.
8476 (tiff_handler): New function, combining the cores of the
8477 old tiff_error_handler and tiff_warning_handler.
8478 This function is rewritten to use vsnprintf and thereby avoid
8479 stack buffer overflows. It uses only the features of vsnprintf
8480 that are common to both POSIX and native Microsoft.
8481 (tiff_error_handler, tiff_warning_handler): Use it.
8482 (tiff_load, gif_load, imagemagick_load_image):
8483 Don't assume :index value fits in 'int'.
8484 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

8486 the integer types that MagickCropImage accepts. Don't assume
8487 Vimagemagick_render_type has a nonnegative value. Don't assume
8488 size_t fits in 'long'.
8489 (gs_load): Use printmax_t to print the widest integers possible.

8507 accurately, and prefer exact match for point under bidi.
8508 Don't advance `row' beyond the last row of the window.
8510 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8511 into disp_prop; all users changed.
8513 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8529 positioning on the newline at EOL of R2L text within L2R
8530 paragraph, and vice versa.
8531 (try_cursor_movement): Check continued rows, in addition to
8532 continuation rows. Fixes unwarranted scroll when point enters a
8533 continued line of R2L text within an L2R paragraph, or vice versa.
8534 (cursor_row_p): Consider the case of point being equal to
8535 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8536 from the end of a short line to the beginning of a continued line
8537 of R2L text within L2R paragraph.
8538 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8561 * xdisp.c (redisplay_window): When computing centering_position,
8562 account for the height of the header line. (Bug#8874)
8564 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8565 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8566 candidate is selected by the mouse, and that candidate has a
8567 composed character under the mouse.
8569 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8570 coordinates reported by pos-visible-in-window-p for a composed

8581 composed buffer positions.
8583 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8585 * image.c (gif_load): Don't assume that each subimage has the same
8586 dimensions as the base image. Handle disposal method that is
8587 "undefined" by the gif spec (Bug#9335).
8589 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8591 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8594 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8596 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8597 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8598 from an Org mode buffer to a Speedbar frame.
8600 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8601 a composition, take its buffer position from IT->cmp_it.charpos.
8602 Fixes cursor positioning at the beginning of a line that begins
8603 with a composed character.
8605 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8607 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8608 character bidirectional type, use STRONG_L instead. Fixes crashes
8609 in a buffer produced by `describe-categories'.
8611 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8612 members before the level stack, so they would be saved and
8613 restored when copying iterator state. Fixes incorrect reordering
8614 around TABs covered by display properties.
8616 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8618 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8638 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8640 2011-08-16 Ken Brown <kbrown@cornell.edu>
8642 Fix memory allocation problems in Cygwin build (Bug#9273).
8644 * unexcw.c ( __malloc_initialized): Declare external variable.
8645 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8647 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8649 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8651 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8653 [CYGWIN] (special_realloc): New function.
8654 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8655 requests to realloc storage in the static heap.
8657 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8659 * bidi.c (bidi_initialize): Remove unused local.
8661 2011-08-15 Eli Zaretskii <eliz@gnu.org>
8664 * biditype.h: Remove file.
8665 * makefile.w32-in ($(BLD)/bidi.$(O)):
8666 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8668 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8670 * chartab.c: Improve commentary for the uniprop_table API.
8672 * bidi.c (bidi_paragraph_init): Support zero value of
8673 bidi_ignore_explicit_marks_for_paragraph_level.
8674 (bidi_initialize): Use uniprop_table instead of including
8675 biditype.h and bidimirror.h.
8677 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8678 coordinates of the iterator when restoring from ppos_it.
8681 2011-08-14 Kenichi Handa <handa@m17n.org>
8683 * process.c (create_process): Call setup_process_coding_systems
8684 after the pid of the process is set to -1 (Bug#8162).
8686 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8688 * xdisp.c (move_it_in_display_line_to): Don't invoke
8689 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8690 ppos_it. Fixes vertical cursor motion when line beginning is
8691 covered by an image. (Bug#9296)
8693 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8695 * nsterm.h (ns_run_ascript): Declare.
8696 (NSAPP_DATA2_RUNASSCRIPT): Define.
8698 * nsfns.m (as_script, as_result, as_status): New static variables.
8699 (ns_run_ascript): New function.
8700 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8701 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8702 the event loop. Get status from as_status (Bug#7276).
8704 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8705 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8706 the event loop (Bug#7276).
8708 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8710 * gnutls.c (QCgnutls_bootprop_priority)
8711 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8712 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8713 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8714 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8715 (QCgnutls_bootprop_verify_hostname_error)
8716 (QCgnutls_bootprop_callbacks_verify): Rename from
8717 Qgnutls_bootprop_..., all uses changed.
8719 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8722 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8724 * xfaces.c (Qframe_set_background_mode): Now static.
8725 * dispextern.h (Qframe_set_background_mode): Remove decl.
8727 * process.c (Fnetwork_interface_info): Declare local only if needed.
8729 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8731 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8732 (Fnetwork_interface_list): Allocate in increments of bytes instead
8733 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8734 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8736 (struct ifflag_def): notrailers is smart on OSX.
8737 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8738 Get hardware address with getifaddrs if available.
8740 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8742 * xdisp.c (iterate_out_of_display_property): xassert that
8743 IT->position is set to within IT->object's boundaries. Break from
8744 the loop as soon as EOB is reached; avoids infloops in redisplay
8745 when IT->position is set up wrongly due to some bug.
8746 Set IT->current to match the bidi iterator unconditionally.
8747 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8748 entry. Force push_it to save on the stack the current
8749 buffer/string position, to be restored by pop_it. Fix flags in
8750 the iterator structure wrt the object coming from a display
8751 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8752 properties. (Bug#9284)
8754 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8756 * fontset.c (fontset_get_font_group): Add proper type checks.
8759 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

8762 and LC_VERSION_MIN_MACOSX.
8763 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8764 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8766 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8768 * xdisp.c (forward_to_next_line_start): Allow to use the
8769 no-display-properties-and-no-overlays under bidi display.
8770 Set disp_pos in the bidi iterator to avoid searches for display
8771 properties and overlays.
8773 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8775 * editfns.c (Fset_time_zone_rule): Document relationship with the
8778 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8779 the font entity extracted from the cache (Bug#8109).
8781 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8783 * composite.c (autocmp_chars): Don't reset point. That is done by
8784 restore_point_unwind (Bug#5984).
8786 2011-08-07 Juri Linkov <juri@jurta.org>
8788 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8789 to show the arg `TIME' instead of `TIMEVAL'.
8791 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8793 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8794 display property strides EOL and includes a newline, as in
8795 longlines-mode. (Bug#9254)
8796 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8797 word-wrap under bidirectional display. (Bug#9224)
8799 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8800 is non-zero, even if the data buffer is NULL. Fixes a crash in
8801 vertical-motion with longlines-mode. (Bug#9254)
8803 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8805 * bidi.c <bidi_cache_total_alloc>: Now static.
8806 (bidi_initialize): Initialize bidi_cache_total_alloc.
8808 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8811 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8812 amount allocated this far in `bidi_cache_total_alloc'.
8813 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8814 non-zero, only free the data buffer without restoring the cache
8815 contents. All callers changed.
8817 * dispextern.h (bidi_unshelve_cache): Update prototype.
8819 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8820 (move_it_in_display_line, move_it_to)
8821 (move_it_vertically_backward, move_it_by_lines): Replace the call
8822 to xfree to an equivalent call to bidi_unshelve_cache.
8823 (move_it_in_display_line_to): Fix logic of returning
8824 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8826 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8828 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8829 came from a string character with a `cursor' property. (Bug#9229)
8831 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8833 * Makefile.in (LIB_PTHREAD): New variable.
8834 (LIBES): Add LIB_PTHREAD (Bug#9216).
8836 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8837 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8839 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8841 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8843 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8845 * xterm.c (x_find_topmost_parent): New function.
8846 (x_set_frame_alpha): Find topmost parent window with
8847 x_find_topmost_parent and set the property there also (bug#9181).
8848 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8850 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8852 * callproc.c (Fcall_process): Avoid vfork clobbering
8853 the local vars buffer, coding_systems, current_dir.
8855 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8857 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8859 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8861 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8862 so that it is not optimized away.
8864 * xdisp.c (compute_display_string_pos): Remove unused local.
8866 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8868 Fix slow cursor motion and scrolling in large buffers with
8869 selective display, like Org Mode buffers. (Bug#9218)
8871 * dispextern.h (struct bidi_it): New member disp_prop_p.
8873 * xdisp.c: Remove one-slot cache of display string positions.
8874 (compute_display_string_pos): Accept an additional argument
8875 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8876 for a display string or property. If found, set DISP_PROP_P
8879 * bidi.c (bidi_fetch_char): Accept an additional argument
8880 DISP_PROP_P, and pass it to compute_display_string_pos.
8881 Only handle text covered by a display string if DISP_PROP_P is returned
8882 non-zero. All callers of bidi_fetch_char changed.
8884 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8886 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8888 2010-12-03 Don March <don@ohspite.net>
8890 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8891 last character M-[char] is translated to ESC [char] (bug#7541).
8893 2011-08-02 Kenichi Handa <handa@m17n.org>
8895 * lisp.h (uniprop_table): Extern it.
8897 * chartab.c (uniprop_table): Make it non-static.
8899 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8901 * xdisp.c (forward_to_next_line_start): Accept additional argument
8902 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8904 (reseat_at_next_visible_line_start): Use the bidi iterator state
8905 returned by forward_to_next_line_start to restore the state of
8906 it->bidi_it after backing up to previous newline. (Bug#9212)
8908 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8910 * regex.c (re_comp): Protoize.
8911 (re_exec): Fix return type.
8912 (regexec): Fix type of `ret'. (Bug#9203)
8914 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8916 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8917 This is needed if max-image-size is a floating-point number.
8919 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8921 * print.c (print_object): Print empty symbol as ##.
8923 * lread.c (read1): Read ## as empty symbol.
8925 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8927 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8928 setting frame foreground color (Bug#9175).
8929 (x_set_background_color): Likewise.
8931 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8932 contents (Bug#9176).
8933 (EmacsTooltip -init): Remove bezels and add shadows to
8936 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8937 or scroll bar (Bug#8470).
8939 * nsfont.m (nsfont_open): Remove assignment to voffset and
8940 unnecessary vars hshink, expand, hd, full_height, min_height.
8941 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8943 * nsterm.h (nsfont_info): Remove voffset field.
8945 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8947 Implement strike-through and overline on NextStep (Bug#8863).
8949 * nsfont.m (nsfont_open): Use underline position provided by font,
8950 instead of hard-coded value of 2.
8951 (nsfont_draw): Call ns_draw_text_decoration instead.
8953 * nsterm.h: Add declaration for ns_draw_text_decoration.
8955 * nsterm.m (ns_draw_text_decoration): New function for drawing
8956 underline, overline, and strike-through.
8957 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8958 ns_draw_text_decoration. Change treatment of cursor drawing to
8959 accommodate underlining, etc.
8961 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8963 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8966 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8968 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8969 Without this fix, if a signal arrives just after memory fills up,
8970 'malloc' might be invoked reentrantly.
8972 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8973 In other words, assume that every image size is allowed, on non-X
8974 hosts. This assumption is probably wrong, but it lets Emacs compile.
8976 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8978 * regex.c (re_iswctype): Convert return values to boolean.
8980 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8982 * xdisp.c (compute_display_string_pos): Don't use cached display
8983 string position if the buffer had its restriction changed.
8986 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8988 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8990 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8992 Integer signedness and overflow and related fixes. (Bug#9079)
8994 * bidi.c: Integer size and overflow fixes.
8995 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8996 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8997 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8998 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8999 (bidi_find_other_level_edge):
9000 Use ptrdiff_t instead of EMACS_INT where either will do.
9001 This works better on 32-bit hosts configured --with-wide-int.
9002 (bidi_cache_ensure_space): Check for size-calculation overflow.
9003 Use % rather than repeated addition, for better worst-case speed.
9004 Don't set bidi_cache_size until after xrealloc returns, because it
9006 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9007 (bidi_cache_ensure_space): Also check that the bidi cache size
9008 does not exceed that of the largest Lisp string or buffer. See Eli
9009 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9011 * alloc.c (__malloc_size_t): Remove.
9012 All uses replaced by size_t. See Andreas Schwab's note
9013 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9015 * image.c: Improve checking for integer overflow.
9016 (check_image_size): Assume that f is nonnull, since
9017 it is always nonnull in practice. This is one less thing to
9018 worry about when checking for integer overflow later.
9019 (x_check_image_size): New function, which checks for integer
9020 overflow issues inside X.
9021 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9022 This removes the need for a memory_full check.
9023 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9024 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9025 (xbm_read_bitmap_data): Change locals back to 'int', since
9026 their values must fit in 'int'.
9027 (xpm_load_image, png_load, tiff_load):
9028 Invoke x_create_x_image_and_pixmap earlier,
9029 to avoid much needless work if the image is too large.
9030 (tiff_load): Treat overly large images as if
9031 x_create_x_image_and_pixmap failed, not as malloc failures.
9032 (gs_load): Use x_check_image_size.
9034 * gtkutil.c: Omit integer casts.
9035 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9036 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9038 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9040 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9041 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9042 would wrongly return t on a 64-bit host.
9044 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9045 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9046 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9047 and therefore cause GCC to emit a bogus diagnostic in some cases.
9049 * image.c: Integer signedness and overflow and related fixes.
9050 This is not an exhaustive set of fixes, but it's time to
9051 record what I've got.
9052 (lookup_pixel_color, check_image_size): Remove redundant decls.
9053 (check_image_size): Don't assume that arbitrary EMACS_INT values
9054 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9055 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9056 (tiff_load, imagemagick_load_image):
9057 Check for overflow in size calculations.
9058 (x_create_x_image_and_pixmap): Remove unnecessary test for
9059 xmalloc returning NULL; that can't happen.
9060 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9061 (xpm_color_bucket): Use better integer hashing function.
9062 (xpm_cache_color): Don't possibly over-allocate memory.
9063 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9064 (gif_memory_source):
9065 Use ptrdiff_t, not int or size_t, to record sizes.
9066 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9067 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9068 either works, as we prefer signed integers.
9069 (tiff_read_from_memory, tiff_write_from_memory):
9070 Return tsize_t, not size_t, since that's what the TIFF API wants.
9071 (tiff_read_from_memory): Don't fail simply because the read would
9072 go past EOF; instead, return a short read.
9073 (tiff_load): Omit no-longer-needed casts.
9074 (Fimagemagick_types): Don't assume size fits into 'int'.
9076 Improve hashing quality when configured --with-wide-int.
9077 * fns.c (hash_string): New function, taken from sxhash_string.
9078 Do not discard information about ASCII character case; this
9079 discarding is no longer needed.
9080 (sxhash-string): Use it. Change sig to match it. Caller changed.
9081 * lisp.h: Declare it.
9082 * lread.c (hash_string): Remove, since we now use fns.c's version.
9083 The fns.c version returns a wider integer if --with-wide-int is
9084 specified, so this should help the quality of the hashing a bit.
9086 * emacs.c: Integer overflow minor fix.
9087 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9088 Define only if GNU_LINUX.
9089 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9091 * dispnew.c: Integer signedness and overflow fixes.
9092 Remove unnecessary forward decls, that were a maintenance hassle.
9093 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9095 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9096 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9097 (prepare_desired_row, line_draw_cost):
9098 Use int, not unsigned, where either works.
9099 (save_current_matrix, restore_current_matrix):
9100 Use ptrdiff_t, not size_t, where either works.
9101 (init_display): Check for overflow more accurately, and without
9102 relying on undefined behavior.
9104 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9105 Remove, replacing with the new symbols in lisp.h. All uses changed.
9106 * fileio.c (make_temp_name):
9107 * filelock.c (lock_file_1, lock_file):
9108 * xdisp.c (message_dolog):
9109 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9110 Use pMd etc. instead.
9111 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9112 replacing the pWIDE etc. symbols removed from editfns.c.
9114 * keyboard.h (num_input_events): Now uintmax_t.
9115 This is (very slightly) less likely to mess up due to wraparound.
9118 * buffer.c: Integer signedness fixes.
9119 (alloc_buffer_text, enlarge_buffer_text):
9120 Use ptrdiff_t rather than size_t when either will do, as we prefer
9123 * alloc.c: Integer signedness and overflow fixes.
9124 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9125 (__malloc_size_t): Default to size_t, not to int.
9126 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9127 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9128 Prefer ptrdiff_t to size_t when either would do, as we prefer
9130 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9131 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9132 Now const. Initialize with values that are in range even if char
9134 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9135 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9136 These functions do the right thing with sizes > 2**32.
9137 (check_depth): Now ptrdiff_t, not int.
9138 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9139 Adjust to new way of storing sizes. Check for size overflow bugs
9141 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9142 slightly wrong anyway, as it missed one instance of
9143 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9144 (refill_memory_reserve): Omit needless cast to size_t.
9145 (mark_object_loop_halt): Mark as externally visible.
9147 * xselect.c: Integer signedness and overflow fixes.
9148 (Fx_register_dnd_atom, x_handle_dnd_message):
9149 Use ptrdiff_t, not size_t, since we prefer signed.
9150 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9151 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9152 x_dnd_atoms_size and x_dnd_atoms_length.
9154 * doprnt.c: Prefer signed to unsigned when either works.
9156 * doprnt.c (doprnt):
9158 * xdisp.c (vmessage):
9159 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9160 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9161 prefer signed arithmetic to avoid comparison confusion.
9162 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9163 but is a bit tricky.
9165 Assume freestanding C89 headers, string.h, stdlib.h.
9166 * data.c, doprnt.c, floatfns.c, print.c:
9167 Include float.h unconditionally.
9168 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9169 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9170 * regex.c: Likewise for stddef.h, string.h.
9171 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9172 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9173 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9174 (STDC_HEADERS): Remove obsolete defines.
9175 * sysdep.c: Include limits.h unconditionally.
9177 Assume support for memcmp, memcpy, memmove, memset.
9178 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9179 * regex.c (memcmp, memcpy):
9180 Remove; we assume C89 now.
9182 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9183 (__malloc_safe_bcopy): Remove; no longer needed.
9185 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9186 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9187 well either way, and we prefer signed to unsigned.
9189 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9191 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9192 closes the connection while we're reading (bug#9182).
9194 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9196 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9197 are specified (Bug#9168).
9199 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9201 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9202 Found by GCC static checking and --with-wide-int on a 32-bit host.
9204 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9206 * xdisp.c (compute_display_string_pos): Fix logic of caching
9207 previous display string position. Initialize cached_prev_pos to
9208 -1. Fixes slow-down at the beginning of a buffer.
9210 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9212 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9213 for attrs[LFACE_FONTSET_INDEX].
9215 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9217 * xml.c (parse_region): Remove unused local
9218 that was recently introduced.
9220 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9222 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9223 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9225 * xdisp.c (move_it_in_display_line_to): Record the best matching
9226 position for TO_CHARPOS while scanning the line, and restore it on
9227 exit if none of the characters scanned was an exact match.
9228 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9229 when exact match is impossible due to invisible text, and the
9230 lines are truncated.
9232 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9234 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9237 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9239 Fix a significant slow-down of cursor motion with C-n, C-p,
9240 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9241 auto-repeat under bidi redisplay in fontified buffers.
9242 * xdisp.c (compute_stop_pos_backwards): New function.
9243 (next_element_from_buffer): Call compute_stop_pos_backwards to
9244 find a suitable prev_stop when we find ourselves before
9246 (reseat): Don't look for prev_stop, as that could mean a very long
9248 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9249 <cached_disp_overlay_modiff>: Cache for last found display string
9251 (compute_display_string_pos): Return the cached position if asked
9252 about the same buffer in the same area of character positions, and
9253 the buffer wasn't changed since the time the display string
9254 position was cached.
9256 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9258 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9259 is an integer, which is important for empty lines. (Bug#9149)
9261 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9263 * frame.c (Fmodify_frame_parameters): In tty case, update the
9264 default face if necessary (Bug#4238).
9266 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9268 * editfns.c (Fstring_to_char): No need to explain what a character
9269 is in the docstring (Bug#6576).
9271 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9273 * xml.c (parse_region): Make sure we always return a tree.
9275 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9277 * xml.c (parse_region): If a document contains only comments,
9280 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9282 * xml.c (make_dom): Return comments, too.
9284 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9287 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9288 and the surrounding thread.
9289 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9290 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9291 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9293 * s/openbsd.h (BROKEN_SIGIO): Define.
9294 * unexelf.c (unexec) [__OpenBSD__]:
9295 Don't update the .mdebug section of the Alpha COFF symbol table.
9297 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9299 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9302 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9304 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9305 This fixes some race conditions on the permissions of any newly
9308 * alloc.c (valid_pointer_p): Use pipe, not open.
9309 This fixes some permissions issues when debugging.
9311 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9312 If fchown fails to set both uid and gid, try to set just gid,
9313 as that is sometimes allowed. Adjust the file's mode to eliminate
9314 setuid or setgid bits that are inappropriate if fchown fails.
9316 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9318 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9319 to compare Lisp_Objects.
9320 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9321 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9322 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9324 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9326 * lread.c (read_integer): Unread even EOF character.
9327 (read1): Likewise. Properly record start position of symbol.
9329 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9330 symbol character follows.
9332 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9334 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9335 This works around a problem with the previous change to Fcopy_file.
9336 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9337 and without this change, GCC might complain about discarding
9338 fchown's return value.
9340 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9342 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9344 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9346 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9348 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9350 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9351 it's used from the C level.
9353 * process.c: Use the same condition for POLL_FOR_INPUT in both
9354 keyboard.c and process.c (bug#1858).
9356 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9358 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9359 (Fgnutls_boot): Use it.
9361 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9363 * doc.c (Fsubstitute_command_keys): Revert last change.
9365 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9367 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9368 quotes the next character, and doesn't affect other longer
9369 sequences (bug#8935).
9371 * lread.c (syms_of_lread): Clarify that is isn't only
9372 `eval-buffer' and `eval-defun' that's affected by
9373 `lexical-binding' (bug#8460).
9375 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9377 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9378 bidi redisplay when a line includes both an image and is truncated.
9380 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9382 Fix minor problems found by static checking.
9383 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9384 (elsz): Now a signed constant, not a size_t var. We prefer signed
9385 types to unsigned, to avoid integer comparison confusion. Without
9386 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9387 "cannot optimize loop, the loop counter may overflow", a symptom
9389 * indent.c (Fvertical_motion): Mark locals as initialized.
9390 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9392 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9394 * search.c (Fre_search_backward): Mention `case-fold-search' in
9395 all the re_search_* functions (bug#8138).
9397 * keyboard.c (Fopen_dribble_file): Document when the file is
9400 2011-07-14 Eli Zaretskii <eliz@gnu.org>

9407 (compute_display_string_end): Accept additional argument STRING.
9408 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9409 (reseat_to_string): Initialize bidi_it->string.s and
9410 bidi_it->string.schars.
9411 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9412 NULL (avoids a crash in bidi_paragraph_init).
9413 Initialize itb.string.lstring.
9414 (init_iterator): Call bidi_init_it only of a valid
9415 buffer position was specified. Initialize paragraph_embedding to
9417 (reseat_to_string): Initialize the bidi iterator.
9418 (display_string): If we need to ignore text properties of
9419 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9420 original value of -1 will not work with bidi.)
9421 (compute_display_string_pos): First arg is now struct
9422 `text_pos *'; all callers changed. Support display properties on
9424 (compute_display_string_end): Support display properties on Lisp
9426 (init_iterator, reseat_1, reseat_to_string): Initialize the
9427 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9428 when iterating on a string not from display properties).
9429 (compute_display_string_pos, compute_display_string_end):
9430 Fix calculation of the object to scan. Fixes an error when using
9432 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9433 base_level_stop; instead, set base_level_stop to BEGV.
9434 Fixes crashes in vertical-motion.
9435 (next_element_from_buffer): Improve commentary for when
9436 the iterator is before prev_stop.
9437 (init_iterator): Initialize bidi_p from the default value of
9438 bidi-display-reordering, not from buffer-local value. Use the
9439 buffer-local value only if initializing for buffer iteration.
9440 (handle_invisible_prop): Support invisible properties on strings
9441 that are being bidi-reordered.
9442 (set_iterator_to_next): Support bidi reordering of C strings and
9444 (next_element_from_string): Support bidi reordering of Lisp
9446 (handle_stop_backwards): Support Lisp strings as well.
9447 (display_string): Support display of R2L glyph rows.
9448 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9449 (init_iterator): Don't initialize it->bidi_p for strings
9451 (reseat_to_string): Initialize it->bidi_p for strings here.
9452 (next_element_from_string, next_element_from_c_string)
9453 (next_element_from_buffer): Add xassert's for correspondence
9454 between IT's object being iterated and it->bidi_it.string
9456 (face_before_or_after_it_pos): Support bidi iteration.
9457 (next_element_from_c_string): Handle the case of the first string
9458 character that is not the first one in the visual order.
9459 (get_visually_first_element): New function, refactored from common
9460 parts of next_element_from_buffer, next_element_from_string, and
9461 next_element_from_c_string.
9462 (tool_bar_lines_needed, redisplay_tool_bar)
9463 (display_menu_bar): Force left-to-right direction. Add a FIXME
9464 comment for making that be controlled by a user option.
9465 (push_it, pop_it): Save and restore the state of the
9466 bidi iterator. Save and restore the bidi_p flag.
9467 (pop_it): Iterate out of display property for string iteration as
9469 (iterate_out_of_display_property): Support iteration over strings.
9470 (handle_single_display_spec): Set up it->bidi_it for iteration
9471 over a display string, and call bidi_init_it.
9472 (handle_single_display_spec, next_overlay_string)
9473 (get_overlay_strings_1, push_display_prop): Set up the bidi
9474 iterator for displaying display or overlay strings.
9475 (forward_to_next_line_start): Don't use the shortcut if
9477 (back_to_previous_visible_line_start): If handle_display_prop
9478 pushed the iterator stack, restore the internal state of the bidi
9479 iterator by calling bidi_pop_it same number of times.
9480 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9481 and we are bidi-iterating, don't decrement the iterator position;
9482 instead, set the first_elt flag in the bidi iterator, to produce
9484 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9485 (push_display_prop): xassert that we are iterating a buffer.
9486 (push_it, pop_it): Save and restore paragraph_embedding member.
9487 (handle_single_display_spec, next_overlay_string)
9488 (get_overlay_strings_1, reseat_1, reseat_to_string)
9489 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9490 correctly. Don't assume unibyte strings are not bidi-reordered.
9491 (compute_display_string_pos)
9492 (compute_display_string_end): Fix handling the case of C string.
9493 (push_it, pop_it): Save and restore from_disp_prop_p.
9494 (handle_single_display_spec, push_display_prop): Set the
9495 from_disp_prop_p flag.
9496 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
9497 (pop_it): Call iterate_out_of_display_property only if we are
9498 popping after iteration over a string that came from a display
9499 property. Fix a typo in popping stretch info. Add an assertion
9500 for verifying that the iterator position is in sync with the bidi
9502 (handle_single_display_spec, get_overlay_strings_1)
9503 (push_display_prop): Fix initialization of paragraph direction for
9504 string when that of the parent object is not yet determined.
9505 (reseat_1): Call bidi_init_it to resync the bidi
9506 iterator with IT's position. (Bug#7616)
9507 (find_row_edges): If ROW->start.pos gives position
9508 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

9516 (try_scrolling, redisplay_window, display_line): Use them when
9517 saving a temporary copy of the iterator and restoring it back.
9518 (back_to_previous_visible_line_start, reseat_1)
9519 (init_iterator): Empty the bidi cache "stack".
9520 (move_it_in_display_line_to): If iterator ended up at
9521 EOL, but we never saw any buffer positions smaller than
9522 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9523 motion in bidi-reordered lines.
9524 (move_it_in_display_line_to): Record prev_method and prev_pos
9525 immediately before the call to set_iterator_to_next. Fixes cursor
9526 motion in bidi-reordered lines with stretch glyphs and strings
9527 displayed in margins. (Bug#8133) (Bug#8867)
9528 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9530 (pos_visible_p): Support positions in bidi-reordered lines.
9531 Save and restore bidi cache.
9533 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9534 (bidi_paragraph_info): Delete unused struct.
9535 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9536 (bidi_cache_start): New variable.
9537 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
9539 (bidi_cache_fetch_state, bidi_cache_search)
9540 (bidi_cache_find_level_change, bidi_cache_iterator_state)
9541 (bidi_cache_find, bidi_peek_at_next_level)
9542 (bidi_level_of_next_char, bidi_find_other_level_edge)
9543 (bidi_move_to_visually_next): Compare cache index with
9544 bidi_cache_start rather than with zero.
9545 (bidi_fetch_char): Accept new argument STRING; all callers
9546 changed. Support iteration over a string. Support strings with
9547 display properties. Support unibyte strings. Fix the type of
9548 `len' according to what STRING_CHAR_AND_LENGTH expects.
9549 (bidi_paragraph_init, bidi_resolve_explicit_1)
9550 (bidi_resolve_explicit, bidi_resolve_weak)

9556 changed to -1 and -2, respectively.
9557 (bidi_char_at_pos): New function.
9558 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
9559 Call it instead of FETCH_MULTIBYTE_CHAR.

9647 The old code sometimes used this field without initializing it.

9650 In theory, the old code could also have corrupted Emacs internals,
9651 though it'd be very unlikely.

9914 (clone_per_buffer_values): Don't assume that

9955 Random fixes. E.g., (random) never returned negative values.
9956 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9957 subseconds part to the entropy, as that's a bit more random.
9958 Prefer signed to unsigned, since the signedness doesn't matter and
9959 in general we prefer signed. When given a limit, use a
9960 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9961 latter isn't right if USE_2_TAGS_FOR_INTS.
9962 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9963 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9976 This is more efficient than Ffile_directory_p and avoids a minor race.
9978 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9980 * buffer.c (Foverlay_put): Say what the return value is
9983 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9986 (barf_or_query_if_file_exists): Make the "File is a directory"
9987 error be more correct.
9989 * fns.c (Frequire): Remove the mention of the .gz files, since
9990 that's installation-specific, but keep the mention of

10006 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10007 Also (re)move comments that are misplaced or no longer relevant.

10011 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

10108 * eval.c (struct backtrace): Simplify and port the data structure.
10109 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10110 signed bit field, as this assumption is not portable and it makes
10111 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10112 "char debug_on_exit : 1" as this is not portable either; instead,
10113 use the portable "unsigned int debug_on_exit : 1". Remove unused
10114 member evalargs. Remove obsolete comments about cc bombing out.

10304 (read1): Check for integer overflow in radices, and in
10305 read-circle numbers.

10350 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10351 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10352 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10353 since we're not interested in debugging glyphs with old libraries.
10354 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10355 GCC 4.6.0's static checking.

10397 (x_session_initialize): Do not assume string length fits in int.
10399 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

10445 Don't assume pid_t and time_t fit in unsigned long.
10446 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10447 (current_lock_owner): Prefer signed type for sizes.
10448 Use memcpy, not strncpy, where memcpy is what is really wanted.
10449 Don't assume (via atoi) that time_t and pid_t fit in int.
10450 Check for time_t and/or pid_t out of range, e.g., via a network share.
10451 Don't alloca where an auto var works fine.

10462 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10464 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10466 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10467 We prefer signed integers, even for size calculations.
10469 * emacs.c: Don't assume string length fits in 'int'.
10470 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10471 (main): Don't invoke strlen when not needed.
10473 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10474 (XD_DEBUG_MESSAGE): Don't waste a byte.
10476 * callproc.c (getenv_internal_1, getenv_internal)
10477 (Fgetenv_internal):
10478 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10480 * lread.c (invalid_syntax): Omit length argument.
10481 All uses changed. This doesn't fix a bug, but it simplifies the
10482 code away from its former Hollerith-constant appearance, and it's
10483 one less 'int' to worry about when looking at integer-overflow issues.
10484 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10486 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10487 This didn't break anything, but it didn't help either.
10488 It's confusing to put a bogus integer in a place where the actual
10489 value does not matter.
10490 (LIST_END_P): Remove unused macro and its bogus comment.
10491 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10493 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10494 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10496 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10497 We prefer signed types, and the value cannot exceed the EMACS_INT
10498 range anyway (because otherwise the length would not be representable).
10499 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10500 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10501 This avoids a GCC warning when WIDE_EMACS_INT.
10503 * indent.c (sane_tab_width): New function.
10504 (current_column, scan_for_column, Findent_to, position_indentation)
10505 (compute_motion): Use it. This is just for clarity.
10506 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10508 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10510 * lisp.h (lint_assume): New macro.
10511 * composite.c (composition_gstring_put_cache):
10512 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10514 * editfns.c, insdel.c:
10515 Omit unnecessary forward decls, to simplify future changes.
10517 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10519 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10521 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10522 Use much-faster test for byte-length change.
10523 Don't assume string byte-length fits in 'int'.
10524 Check that character arg fits in 'int'.
10525 (mapcar1): Declare byte as byte, for clarity.
10527 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10529 * fns.c (concat): Catch string overflow earlier.
10530 Do not rely on integer wraparound.
10532 * dispextern.h (struct it.overlay_strings_charpos)
10533 (struct it.selective): Now EMACS_INT, not int.
10534 * xdisp.c (forward_to_next_line_start)
10535 (back_to_previous_visible_line_start)
10536 (reseat_at_next_visible_line_start, next_element_from_buffer):
10537 Don't arbitrarily truncate the value of 'selective' to int.
10539 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10541 * composite.c: Don't truncate sizes to 'int'.
10542 (composition_gstring_p, composition_reseat_it)
10543 (composition_adjust_point): Use EMACS_INT, not int.
10544 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10545 not EMACS_UINT, for indexes.
10547 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10549 * buffer.c: Include <verify.h>.
10550 (struct sortvec.priority, struct sortstr.priority):
10551 Now EMACS_INT, not int.
10552 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10553 (struct sortstr.size, record_overlay_string)
10554 (struct sortstrlist.size, struct sortlist.used):
10555 Don't truncate size to int.
10556 (record_overlay_string): Check for size-calculation overflow.
10557 (init_buffer_once): Check at compile-time, not run-time.
10559 2011-06-22 Jim Meyering <meyering@redhat.com>
10561 Don't leak an XBM-image-sized buffer
10562 * image.c (xbm_load): Free the image buffer after using it.
10564 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10567 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10568 that Sun C diagnosed.
10569 * fns.c (secure_hash): Fix pointer signedness issue.
10570 * intervals.c (static_offset_intervals): New function.
10571 (offset_intervals): Use it.
10573 2011-06-21 Leo Liu <sdl.web@gmail.com>
10576 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10579 * fns.c (secure_hash): Rename from crypto_hash_function and change
10580 the first arg to accept symbols.
10581 (Fsecure_hash): New primitive.
10582 (syms_of_fns): New symbols.
10584 2011-06-20 Deniz Dogan <deniz@dogan.se>
10586 * process.c (Fset_process_buffer): Clarify return value in
10589 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10591 * dispnew.c (add_window_display_history): Use BVAR.
10593 * xdisp.c (debug_method_add): Use BVAR.
10594 (check_window_end, dump_glyph_matrix, dump_glyph)
10595 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10597 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10600 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10601 check till after the cache is created in init_frame_faces.
10603 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10605 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10607 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10609 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10610 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10611 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10613 Improve buffer-overflow checking (Bug#8873).
10614 * fileio.c (Finsert_file_contents):
10615 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10616 Remove the old (too-loose) buffer overflow checks.
10617 They weren't needed, since make_gap checks for buffer overflow.
10618 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10619 The old code merely checked for Emacs fixnum overflow, and relied
10620 on undefined (wraparound) behavior. The new code avoids undefined
10621 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10623 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10624 Tune. Don't use wider integers than needed. Don't use alloca.
10625 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10627 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10629 * insdel.c, lisp.h (buffer_overflow): New function.
10630 (insert_from_buffer_1, replace_range, replace_range_2):
10631 * insdel.c (make_gap_larger):
10632 * editfns.c (Finsert_char):
10633 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10635 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10637 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10639 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10641 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10642 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10644 * fileio.c: Don't assume EMACS_INT fits in off_t.
10645 (emacs_lseek): New static function.
10646 (Finsert_file_contents, Fwrite_region): Use it.
10647 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10649 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10651 * fns.c: Don't overflow int when computing a list length.
10652 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10653 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10654 truncation on 64-bit hosts. Check for QUIT every
10655 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10656 faster and is responsive enough.
10657 (Flength): Report an error instead of overflowing an integer.
10658 (Fsafe_length): Return a float if the value is not representable
10659 as a fixnum. This shouldn't happen except in contrived situations.
10660 (Fnthcdr, Fsort): Don't assume list length fits in int.
10661 (Fcopy_sequence): Don't assume vector length fits in int.
10663 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10664 (header_size, word_size): New constants.
10665 (allocate_vectorlike): Don't check size overflow here.
10666 (allocate_vector): Check it here instead, since this is the only
10667 caller of allocate_vectorlike that could cause overflow.
10668 Check that the new vector's length is representable as a fixnum.
10670 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10671 The previous code was bogus. For example, next_almost_prime (32)
10672 returned 39, which is undesirable as it is a multiple of 3; and
10673 next_almost_prime (24) returned 25, which is a multiple of 5 so
10674 why was the code bothering to check for multiples of 7?
10676 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10678 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10680 Variadic C functions now count arguments with ptrdiff_t.
10681 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10682 Back then I didn't know that the Emacs coding style prefers signed int.
10683 Also, in the meantime I found a few more instances where arguments
10684 were being counted with int, which may truncate counts on 64-bit
10685 machines, or EMACS_INT, which may be unnecessarily wide.
10686 * lisp.h (struct Lisp_Subr.function.aMANY)
10687 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10688 Arg counts are now ptrdiff_t, not size_t.
10689 All variadic functions and their callers changed accordingly.
10690 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10691 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10692 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10693 * callint.c (Fcall_interactively): Check arg count for overflow,
10694 to avoid potential buffer overrun. Use signed char, not 'int',
10695 for 'varies' array, so that we needn't bother to check its size
10696 calculation for overflow.
10697 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10698 * eval.c (apply_lambda):
10699 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10700 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10701 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10703 * callint.c (Fcall_interactively): Don't use index var as event count.
10705 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10706 * mem-limits.h (SIZE): Remove; no longer used.
10708 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10710 Remove unnecessary casts.
10711 * xterm.c (x_term_init):
10712 * xfns.c (x_set_border_pixel):
10713 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10714 These aren't needed now that we assume ANSI C.
10716 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10717 It's more likely to cause problems (due to unsigned overflow)
10720 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10722 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10724 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10726 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10728 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10730 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10732 GLYPH_CODE_FACE returns EMACS_INT, not int.
10733 * dispextern.h (merge_faces):
10734 * xfaces.c (merge_faces):
10735 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10736 Don't assume EMACS_INT fits in int.
10738 * character.h (CHAR_VALID_P): Remove unused parameter.
10739 * fontset.c, lisp.h, xdisp.c: All uses changed.
10741 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10743 * fns.c (concat): Minor tuning based on overflow analysis.
10744 This doesn't fix any bugs. Use int to hold character, instead
10745 of constantly refetching from Emacs object. Use XFASTINT, not
10746 XINT, for value known to be a character. Don't bother comparing
10747 a single byte to 0400, as it's always less.
10749 * floatfns.c (Fexpt):
10750 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10752 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10755 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10757 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10758 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10759 incorrectly succeed when S was a string, because 4294967386 was
10760 truncated before it was used.
10762 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10763 Otherwise, an out-of-range integer could cause undefined behavior
10766 * composite.c: Use int, not EMACS_INT, for characters.
10767 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10768 EMACS_INT, for values that are known to be in character range.
10769 This doesn't fix any bugs but is the usual style inside Emacs and
10770 may generate better code on 32-bit machines.
10772 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10773 This is for reasons similar to the recent CHAR_STRING fix.
10774 * charset.c (Fencode_char): Check that character arg is actually
10775 a character. Pass an int to ENCODE_CHAR.
10776 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10777 wider than 'int', as a compile-time check to prevent future regressions
10780 * character.c (char_string): Remove unnecessary casts.
10782 Make sure a 64-bit char is never passed to CHAR_STRING.
10783 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10784 by silently ignoring the top 32 bits, allowing some values
10785 that were far too large to be valid characters.
10786 * character.h: Include <verify.h>.
10787 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10788 arguments are no wider than unsigned, as a compile-time check
10789 to prevent future regressions in this area.
10791 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10792 (Fsubst_char_in_region):
10794 * xdisp.c (decode_mode_spec_coding):
10795 Adjust to CHAR_STRING's new requirement.
10796 * editfns.c (Finsert_char, Fsubst_char_in_region):
10797 * fns.c (concat): Check that character args are actually
10798 characters. Without this test, these functions did the wrong
10799 thing with wildly out-of-range values on 64-bit hosts.
10801 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10802 These casts should not be needed on 32-bit hosts, either.
10803 * keyboard.c (read_char):
10804 * lread.c (Fload): Remove casts to unsigned.
10806 * lisp.h (UNSIGNED_CMP): New macro.
10807 This fixes comparison bugs on 64-bit hosts.
10808 (ASCII_CHAR_P): Use it.
10809 * casefiddle.c (casify_object):
10810 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10811 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10812 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10813 * dispextern.h (FACE_FROM_ID):
10814 * keyboard.c (read_char): Use UNSIGNED_CMP.
10816 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10817 not to EMACS_INT, to avoid GCC warning.
10819 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10821 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10822 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10823 isn't needed on 32-bit machines.
10825 * buffer.c (Fgenerate_new_buffer_name):
10826 Use EMACS_INT for count, not int.
10827 (advance_to_char_boundary): Return EMACS_INT, not int.
10829 * data.c (Qcompiled_function): Now static.
10831 * window.c (window_body_lines): Now static.
10833 * image.c (gif_load): Rename local to avoid shadowing.
10835 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10836 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10837 * alloc.c (make_save_value): Integer argument is now of type
10838 ptrdiff_t, not int.
10839 (mark_object): Use ptrdiff_t, not int.
10840 * lisp.h (pD): New macro.
10841 * print.c (print_object): Use it.
10843 * alloc.c: Use EMACS_INT, not int, to count objects.
10844 (total_conses, total_markers, total_symbols, total_vector_size)
10845 (total_free_conses, total_free_markers, total_free_symbols)
10846 (total_free_floats, total_floats, total_free_intervals)
10847 (total_intervals, total_strings, total_free_strings):
10848 Now EMACS_INT, not int. All uses changed.
10849 (Fgarbage_collect): Compute overall total using a double, so that
10850 integer overflow is less likely to be a problem. Check for overflow
10851 when converting back to an integer.
10852 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10853 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10854 These were 'int' variables that could overflow on 64-bit hosts;
10855 they were never used, so remove them instead of repairing them.
10856 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10857 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10858 Previously, this ceilinged at INT_MAX, but that doesn't work on
10860 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10862 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10863 (allocate_vectorlike): Check for ptrdiff_t overflow.
10864 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10865 when a (possibly-narrower) signed value would do just as well.
10866 We prefer using signed arithmetic, to avoid comparison confusion.
10868 * alloc.c: Catch some string size overflows that we were missing.
10869 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10870 for convenience in STRING_BYTES_MAX.
10871 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10872 The definition here is exact; the one in lisp.h was approximate.
10873 (allocate_string_data): Check for string overflow. This catches
10874 some instances we weren't catching before. Also, it catches
10875 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10876 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10877 and ptrdiff_t and EMACS_INT are both 64 bits.
10879 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10880 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10881 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10883 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10885 * alloc.c (Fmake_string): Check for out-of-range init.
10887 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10889 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10891 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10893 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10894 xg_get_default_scrollbar_width.
10896 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10897 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10898 (style_changed_cb): Call update_theme_scrollbar_width and call
10899 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10900 all frames (Bug#8505).
10901 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).

11351 Fframe_first_window and Fset_frame_selected_window to window.h.
11353 * window.h: Move EXFUNS for Fframe_root_window,
11354 Fframe_first_window and Fset_frame_selected_window here from

11358 (Fframe_root_window, Fframe_selected_window)
11359 (Fset_frame_selected_window): Move to window.c.
11360 (Factive_minibuffer_window): Move to minibuf.c.
11361 (Fother_visible_frames_p): New function.

11377 (Fwindow_minibuffer_p): Move up in code and simplify.
11378 (Fset_frame_selected_window): Move here from frame.c.
11380 (Fselected_window, select_window, Fselect_window): Move up in
11381 code. Minor doc-string fixes.
11383 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
11385 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
11386 Do not assume that spare memory exists; that assumption is valid
11387 only if SYSTEM_MALLOC.
11388 (LARGE_REQUEST): New macro, so that the issue of large requests
11389 is separated from the issue of spare memory.
11391 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
11393 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

11419 New error handlers.
11420 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
11421 Obey Vx_select_enable_clipboard_manager. Catch errors in
11422 x_clipboard_manager_save (Bug#8779).
11423 (Vx_select_enable_clipboard_manager): New variable.
11424 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11426 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11428 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11430 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11432 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11433 in the current matrix if keep_current_p is non-zero.

11439 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11441 Support bidi reordering of text covered by display properties.
11443 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11444 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11445 (bidi_cache_search, bidi_cache_iterator_state)
11446 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11447 (bidi_level_of_next_char, bidi_move_to_visually_next):
11448 Support character positions inside a run of characters covered by a
11450 (bidi_paragraph_init, bidi_resolve_explicit_1)
11451 (bidi_level_of_next_char): Call bidi_fetch_char and
11452 bidi_fetch_char_advance instead of FETCH_CHAR and
11453 FETCH_CHAR_ADVANCE.

11455 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11457 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11458 instead of using explicit *_CHAR codes.
11459 (bidi_resolve_explicit, bidi_resolve_weak):
11460 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11461 bidirectional text is supported only in multibyte buffers.
11462 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11463 it to initialize the frame_window_p member of struct bidi_it.
11464 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11465 (bidi_resolve_explicit, bidi_resolve_weak)

11467 bidi_it->nchars is non-positive.
11468 (bidi_level_of_next_char): Don't try to lookup the cache for the
11469 next/previous character if nothing is cached there yet, or if we
11470 were just reseat()'ed to a new position.
11472 * xdisp.c (set_cursor_from_row): Set start and stop points
11473 according to the row's direction when priming the loop that looks
11474 for the glyph on which to display cursor.
11475 (single_display_spec_intangible_p): Function deleted.
11476 (display_prop_intangible_p): Reimplement to call
11477 handle_display_spec instead of single_display_spec_intangible_p.
11478 Accept 3 additional arguments needed by handle_display_spec.
11479 This fixes incorrect cursor motion across display property with complex
11480 values: lists, `(when COND...)' forms, etc.
11481 (single_display_spec_string_p): Support property values that are
11482 lists with the argument STRING its top-level element.
11483 (display_prop_string_p): Fix the condition for processing a
11484 property that is a list to be consistent with handle_display_spec.
11485 (handle_display_spec): New function, refactored from the
11486 last portion of handle_display_prop.
11487 (compute_display_string_pos): Accept additional argument
11488 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11489 value of a `display' property is a "replacing spec".
11490 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11491 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11492 the display property, but just return a value indicating whether
11493 the display property will replace the characters it covers.
11494 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11495 frame_window_p members of struct bidi_it.
11496 (compute_display_string_pos, compute_display_string_end):
11498 (push_it): Accept second argument POSITION, where pop_it should
11499 jump to continue iteration.
11500 (reseat_1): Initialize bidi_it.disp_pos.
11502 * keyboard.c (adjust_point_for_property): Adjust the call to
11503 display_prop_intangible_p to its new signature.
11505 * dispextern.h (struct bidi_it): New member frame_window_p.
11506 (bidi_init_it): Update prototypes.
11507 (display_prop_intangible_p): Update prototype.
11508 (compute_display_string_pos, compute_display_string_end):
11509 Declare prototypes.
11510 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11513 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11515 Malloc failure behavior now depends on size of allocation.
11516 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11517 * lisp.h: Change signatures accordingly.
11518 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11519 All callers changed. (Bug#8762)
11521 * gnutls.c: Use Emacs's memory allocators.
11522 Without this change, the gnutls library would invoke malloc etc.
11523 directly, which causes problems on non-SYNC_INPUT hosts, and which
11524 runs afoul of improving memory_full behavior. (Bug#8761)
11525 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11526 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11527 xfree instead of the default malloc, realloc, free.
11528 (Fgnutls_boot): No need to check for memory allocation failure,
11529 since xmalloc does that for us.
11531 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11532 * category.c (hash_get_category_set):
11533 * ccl.c (ccl_driver):
11534 * charset.c (Fdefine_charset_internal):

11545 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11546 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11547 * image.c (make_image, search_image_cache, lookup_image)
11548 (xpm_put_color_table_h):
11549 * lisp.h (struct Lisp_Hash_Table):
11550 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11551 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11552 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11553 * alloc.c (allocate_vectorlike):
11554 Check for overflow in vector size calculations.
11555 * ccl.c (ccl_driver):
11556 Check for overflow when converting EMACS_INT to int.
11557 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11558 need to be updated by these changes.
11559 * fns.c (make_hash_table, maybe_resize_hash_table):
11560 Check for integer overflow with large hash tables.
11561 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11562 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11563 (SXHASH_REDUCE): New macro.
11564 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11565 Use it instead of discarding useful hash info with large hash values.
11566 (sxhash_float): New function.
11567 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11568 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11569 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11570 Rewrite to use FIXNUM_BITS, as this simplifies things.
11571 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11572 Adjust signatures to match updated version of code.
11573 (consing_since_gc): Now EMACS_INT, since a single hash table can
11574 use more than INT_MAX bytes.
11576 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11578 Make it possible to build with GCC-4.6+ -O2 -flto.
11580 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11582 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11584 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11585 Call minibuffer-inactive-mode.
11587 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11589 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11590 Update dependencies.
11592 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11594 * data.c (init_data): Remove code for UTS, this system is not
11597 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11599 Don't force ./temacs to start in terminal mode.
11601 * frame.c (make_initial_frame): Initialize faces in all cases, not
11602 only when CANNOT_DUMP is defined.
11603 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11605 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11607 * dispnew.c (add_window_display_history): Use const for the string
11608 pointer. Remove declaration, not needed.
11610 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11612 Use 'inline', not 'INLINE'.
11613 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11614 * alloc.c, fontset.c (INLINE): Remove.
11615 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11616 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11617 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11618 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11619 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11621 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11623 Make it possible to run ./temacs.
11625 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11626 syms_of_callproc does the same thing. Remove test for
11627 "initialized", do it in the caller.
11628 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11630 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11632 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11633 (read_minibuf): Use get_minibuffer.
11634 (syms_of_minibuf): Use DEFSYM.
11635 (Qmetadata): New var.
11636 * data.c (Qbuffer): Don't make it static.
11637 (syms_of_data): Use DEFSYM.
11639 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11641 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11642 (CCL_CODE_MIN): New macro.
11644 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11646 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11648 * eval.c (Qdebug): Now static.
11649 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11650 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11651 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11653 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11655 * image.c: Various fixes to ImageMagick code comments.
11656 (Fimagemagick_types): Doc fix.
11658 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11660 Minor fixes prompted by GCC 4.6.0 warnings.
11662 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11664 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11665 (x_clipboard_manager_save_all): Move extern decl to ...
11666 * xterm.h: ... here, so that it can be checked for consistency.
11668 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11670 * xselect.c (x_clipboard_manager_save_frame)
11671 (x_clipboard_manager_save_all): New functions.
11672 (Fx_clipboard_manager_save): Lisp function deleted.
11674 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11675 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11677 * xterm.h: Update prototype.
11679 2011-05-28 William Xu <william.xwl@gmail.com>
11681 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11682 exiting (Bug#8239).
11684 2011-05-28 Jim Meyering <meyering@redhat.com>
11686 Avoid a sign-extension bug in crypto_hash_function.
11687 * fns.c (to_uchar): Define.
11688 (crypto_hash_function): Use it to convert some newly-signed
11689 variables to unsigned, to avoid sign-extension bugs. For example,
11690 without this change, (md5 "truc") would evaluate to
11691 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11692 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11693 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11695 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11697 Integer overflow fixes.
11699 * dbusbind.c: Serial number integer overflow fixes.
11700 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11701 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11702 to hold a serial number that is too large for a fixnum.
11703 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11704 Check for serial numbers out of range. Decode any serial number
11705 that was so large that it became a float. (Bug#8722)
11707 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11708 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11709 Use XFASTINT rather than XUINT when numbers are nonnegative.
11710 (xd_append_arg, Fdbus_method_return_internal):
11711 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11712 arguments, check that Lisp number is nonnegative, rather than
11713 silently wrapping negative numbers around. (Bug#8722)
11714 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11717 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11719 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11721 ccl: Add integer overflow checks.
11722 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11723 (IN_INT_RANGE): New macros.
11724 (ccl_driver): Use them to check for integer overflow when
11725 decoding a CCL program. Many of the new checks are whether XINT (x)
11726 fits in int; it doesn't always, on 64-bit hosts. The new version
11727 doesn't catch all possible integer overflows, but it's an
11728 improvement. (Bug#8719)
11730 * alloc.c (make_event_array): Use XINT, not XUINT.
11731 There's no need for unsigned here.
11733 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11734 This follows up to the 2011-05-06 change that substituted uintptr_t
11735 for EMACS_INT. This case wasn't caught back then.
11737 Rework Fformat to avoid integer overflow issues.
11738 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11739 now (part of C89). Include <verify.h>.
11740 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11741 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11742 (Fformat): Avoid the prepass trying to compute sizes; it was only
11743 approximate and thus did not catch overflow reliably. Instead, walk
11744 through the format just once, formatting and computing sizes as we go,
11745 checking for integer overflow at every step, and allocating a larger
11746 buffer as needed. Keep track separately whether the format is
11747 multibyte. Keep only the most-recently calculated precision, rather
11748 than them all. Record whether each argument has been converted to
11749 string. Use EMACS_INT, not int, for byte and char and arg counts.
11750 Support field widths and precisions larger than INT_MAX. Avoid
11751 sprintf's undefined behavior with conversion specifications such as %#d
11752 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11753 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11754 formatting out-of-range floating point numbers with int
11755 formats. (Bug#8668)
11757 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11759 * data.c: Avoid integer truncation in expressions involving floats.
11760 * data.c: Include <intprops.h>.
11761 (arith_driver): When there's an integer overflow in an expression
11762 involving floating point, convert the integers to floating point
11763 so that the resulting value does not suffer from catastrophic
11764 integer truncation. For example, on a 64-bit host (* 4
11765 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11766 Do not rely on undefined behavior after integer overflow.
11768 merge count_size_as_multibyte, parse_str_to_multibyte
11769 * character.c, character.h (count_size_as_multibyte):
11770 Rename from parse_str_to_multibyte; all uses changed.
11771 Check for integer overflow.
11772 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11773 since it's now a duplicate of the other. This is more of
11774 a character than a buffer op, so better that it's in character.c.
11775 * fns.c, print.c: Adjust to above changes.
11777 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11779 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11781 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11783 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11784 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11785 (x_clipboard_manager_save): Now static.
11786 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11788 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11789 (crypto_hash_function): Now static.
11790 Fix pointer signedness problems. Avoid unnecessary initializations.
11792 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11794 * termhooks.h (Vselection_alist): Make it terminal-local.
11796 * terminal.c (create_terminal): Initialize it.
11798 * xselect.c: Support for clipboard managers.
11799 (Vselection_alist): Move to termhooks.h as terminal-local var.
11800 (LOCAL_SELECTION): New macro.
11801 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11802 (symbol_to_x_atom): Remove gratuitous arg.
11803 (x_handle_selection_request, lisp_data_to_selection_data)
11804 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11805 (x_own_selection, x_get_local_selection, x_convert_selection):
11806 New arg, specifying work frame. Use terminal-local Vselection_alist.
11807 (some_frame_on_display): Delete unused function.
11808 (Fx_own_selection_internal, Fx_get_selection_internal)
11809 (Fx_disown_selection_internal, Fx_selection_owner_p)
11810 (Fx_selection_exists_p): New optional frame arg.
11811 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11812 (x_handle_selection_clear): Don't treat other terminals with the
11813 same keyboard specially. Use the terminal-local Vselection_alist.
11814 (x_clear_frame_selections): Use Frun_hook_with_args.
11816 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11818 * xterm.h: Add support for those atoms.
11820 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11822 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11823 (converted_selections, conversion_fail_tag): New global variables.
11824 (x_selection_request_lisp_error): Free the above.
11825 (x_get_local_selection): Remove unnecessary code.
11826 (x_reply_selection_request): Args changed; handle arbitrary array
11827 of converted selections stored in converted_selections.
11828 Separate the XChangeProperty and SelectionNotify steps.
11829 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11830 (x_convert_selection): New function.
11831 (x_handle_selection_event): Simplify.
11832 (x_get_foreign_selection): Don't ignore incoming requests while
11833 waiting for an answer; this will fail when we implement
11834 SAVE_TARGETS, and seems unnecessary anyway.
11835 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11836 (Vx_sent_selection_functions): Doc fix.
11838 2011-05-26 Leo Liu <sdl.web@gmail.com>
11840 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11842 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11844 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11846 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11847 for fringe update if it has periodic bitmap.
11848 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11849 and fringe_bitmap_periodic_p.
11851 * fringe.c (get_fringe_bitmap_data): New function.
11852 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11853 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11854 row. Mark glyph row for fringe update if periodicity changed.
11856 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11857 for fringe update unless it has periodic bitmap.
11859 2011-05-25 Kenichi Handa <handa@m17n.org>
11861 * xdisp.c (get_next_display_element): Set correct it->face_id for
11862 a static composition.
11864 2011-05-24 Leo Liu <sdl.web@gmail.com>
11867 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11869 * fns.c (crypto_hash_function, Fsha1): New function.
11870 (Fmd5): Use crypto_hash_function.
11871 (syms_of_fns): Add Ssha1.
11873 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11875 * gnutls.c: Remove unused macros.
11876 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11877 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11878 Remove macros that are defined and never used.
11879 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11881 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11883 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11884 (Fx_get_selection_internal): Minor cleanup.
11885 (Fx_own_selection_internal): Rename arguments for consistency with
11888 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11890 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11892 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11894 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11896 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11898 * dispnew.c (scrolling_window): Don't exclude the case that the
11899 last enabled row in the desired matrix touches the bottom boundary.
11901 2011-05-21 Glenn Morris <rgm@gnu.org>
11903 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11904 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11905 and add some more files.
11907 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11909 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11910 report_file_error introduced by the change from 2011-05-07.
11912 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11914 * systime.h (Time): Define only if emacs is defined.
11915 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11916 where the include path doesn't have X11/X.h by default. See
11917 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11919 2011-05-20 Kenichi Handa <handa@m17n.org>
11921 * composite.c (find_automatic_composition): Fix previous change.
11923 2011-05-20 Glenn Morris <rgm@gnu.org>
11925 * lisp.mk: New file, split from Makefile.in.
11926 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11927 (shortlisp): Remove.
11928 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11930 2011-05-19 Glenn Morris <rgm@gnu.org>
11932 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11933 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11934 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11935 (lisp): Set the order to that of loadup.el.
11936 (shortlisp): Make it a copy of $lisp.
11937 (SOME_MACHINE_LISP): Remove.
11938 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11939 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11941 2011-05-18 Kenichi Handa <handa@m17n.org>
11943 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11944 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11945 (find_automatic_composition): Mostly rewrite for efficiency.
11947 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11949 * makefile.w32-in: Update dependencies.
11951 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11953 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11954 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11956 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11958 Fix some integer overflow issues, such as string length overflow.
11960 * insdel.c (count_size_as_multibyte): Check for string overflow.
11962 * character.c (lisp_string_width): Check for string overflow.
11963 Use EMACS_INT, not int, for string indexes and lengths; in
11964 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11965 the resulting string length overflows an EMACS_INT; instead,
11966 report a string overflow if no precision given. When checking for
11967 precision exhaustion, use a check that cannot possibly have
11968 integer overflow. (Bug#8675)
11969 * character.h (lisp_string_width): Adjust to new signature.
11971 * alloc.c (string_overflow): New function.
11972 (Fmake_string): Use it. This doesn't change behavior, but saves
11973 a few bytes and will simplify future changes.
11974 * character.c (string_escape_byte8): Likewise.
11975 * lisp.h (string_overflow): New decl.
11977 Fixups, following up to the user-interface timestamp change.
11978 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11979 for UI timestamps, instead of unsigned long.
11980 * msdos.c (mouse_get_pos): Likewise.
11981 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11982 * w32gui.h (Time): Define by including "systime.h" rather than by
11983 declaring it ourselves. (Bug#8664)
11985 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11986 * image.c (clear_image_cache): Likewise.
11988 * term.c (term_mouse_position): Don't assume time_t wraparound.
11990 Be more systematic about user-interface timestamps.
11991 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11992 and sometimes 'EMACS_UINT', to represent these timestamps.
11993 This change causes it to use 'Time' uniformly, as that's what X uses.
11994 This makes the code easier to follow, and makes it easier to catch
11995 integer overflow bugs such as Bug#8664.
11996 * frame.c (Fmouse_position, Fmouse_pixel_position):
11997 Use Time, not unsigned long, for user-interface timestamps.
11998 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11999 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12000 * keyboard.h (last_event_timestamp): Likewise.
12001 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12002 * menu.h (xmenu_show): Likewise.
12003 * term.c (term_mouse_position): Likewise.
12004 * termhooks.h (struct input_event.timestamp): Likewise.
12005 (struct terminal.mouse_position_hook): Likewise.
12006 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12007 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12008 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12009 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12010 what it was before.
12011 * menu.h, termhooks.h: Include "systime.h", for Time.
12013 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12014 Don't assume that the difference between two unsigned long values
12015 can fit into an integer. At this point, we know button_down_time
12016 <= event->timestamp, so the difference must be nonnegative, so
12017 there's no need to cast the result if double-click-time is
12018 nonnegative, as it should be; check that it's nonnegative, just in
12019 case. This bug is triggered when events are more than 2**31 ms
12020 apart (about 25 days). (Bug#8664)
12022 * xselect.c (last_event_timestamp): Remove duplicate decl.
12023 (x_own_selection): Remove needless cast to unsigned long.
12025 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12026 that always fit in int. Use a sentinel instead of a counter, to
12027 avoid a temp and to allay GCC's concerns about possible int overflow.
12028 * frame.h (struct frame): Use int for menu_bar_items_used
12029 instead of EMACS_INT, since it always fits in int.
12031 * menu.c (grow_menu_items): Check for int overflow.
12033 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12035 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12036 Before, the code was not consistent. These values cannot exceed
12037 2**31 - 1 so there's no need to make them unsigned.
12038 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12039 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12040 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12042 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12044 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12045 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12046 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12047 presumably because the widths might not match.
12049 * window.c (size_window): Avoid needless test at loop start.
12051 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12053 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12055 2011-05-12 Drew Adams <drew.adams@oracle.com>
12057 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12059 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12061 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12062 `width' to `bar_area_x' and `bar_area_width', respectively.
12063 (x_scroll_run): Take account of fringe background extension.
12065 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12066 Rename local vars `left' and `width' to `bar_area_x' and
12067 `bar_area_width', respectively.
12068 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12069 background extension.
12071 2011-05-10 Jim Meyering <meyering@redhat.com>
12073 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12075 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12077 * image.c (Finit_image_library): Return t for built-in image types,
12078 like pbm and xbm. (Bug#8640)
12080 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12082 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12084 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12086 * w32console.c (Fset_screen_color): Doc fix.
12087 (Fget_screen_color): New function.
12088 (syms_of_ntterm): Defsubr it.
12090 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12091 unlink the temporary file if Fcall_process didn't create it in the
12093 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12094 child process will be redirected to a file specified with `:file'.
12095 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12096 cue to call_process_cleanup not to close that handle.
12098 2011-05-07 Ben Key <bkey76@gmail.com>
12100 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12101 one of two shell specific rules, either bootstrap-temacs-CMD or
12102 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12103 to the previous implementation of the bootstrap-temacs rule.
12104 The bootstrap-temacs-CMD rule is similar to the previous
12105 implementation of the bootstrap-temacs rule except that it
12106 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12109 These changes, along with some changes to nt/configure.bat,
12110 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12111 earlier fix to add support for --cflags and --ldflags options
12112 that include quotes so that it works whether make uses cmd or
12115 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12117 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12118 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12120 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12121 a string. Handle both cases.
12122 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12123 (Fdbus_register_method): Use Qinvalid_function.
12125 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12127 * makefile.w32-in: Update dependencies.
12128 (LISP_H): Add inttypes.h and stdin.h.
12129 (PROCESS_H): Add unistd.h.
12131 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12133 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12134 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12136 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12138 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12140 * term.c (vfatal): Remove stray call to va_end.
12141 It's not needed and the C Standard doesn't allow it here anyway.
12143 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12144 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12146 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12149 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12151 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12153 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12155 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12157 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12159 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12160 * charset.c (Fdefine_charset_internal): Don't initialize
12161 charset.code_space[15]. The value was garbage, on hosts with
12162 32-bit int (Bug#8600).
12164 * lread.c (read_integer): Be more consistent with string-to-number.
12165 Use string_to_number to do the actual conversion; this avoids
12166 rounding errors and fixes some other screwups. Without this fix,
12167 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12168 (digit_to_number): Move earlier, for benefit of read_integer.
12169 Return -1 if the digit is out of range for the base, -2 if it is
12170 not a digit in any supported base. (Bug#8602)
12172 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12174 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12175 to match comment at start of function. This also removes a
12176 GCC warning about overflow in a 32+64-bit port.
12178 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12180 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12181 Reported by Stefan Monnier in
12182 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12183 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12184 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12186 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12187 (EMACS_UINTPTR): Likewise, with uintptr_t.
12189 * lisp.h: Prefer 64-bit EMACS_INT if available.
12190 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12191 on 32-bit hosts that have 64-bit int, so that they can access
12193 However, temporarily disable this change unless the temporary
12194 symbol WIDE_EMACS_INT is defined.
12196 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12198 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12199 This removes an assumption that EMACS_INT and long are the same
12200 width as pointers. The assumption is true for Emacs porting targets
12201 now, but we want to make other targets possible.
12202 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12203 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12204 In the rest of the code, change types of integers that hold casted
12205 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12206 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12207 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12208 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12209 No need to cast type when ORing.
12210 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12211 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12212 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12213 assume EMACS_INT is the same width as char *.
12214 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12215 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12216 Remove no-longer-needed casts.
12217 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12218 (xg_tool_bar_help_callback, xg_make_tool_item):
12219 Use EMACS_INTPTR to hold an integer
12220 that will be cast to void *; this can avoid a GCC warning
12221 if EMACS_INT is not the same width as void *.
12222 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12223 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12224 (current_message_1, set_message_1):
12225 Use a local to convert to proper width without a cast.
12226 * xmenu.c (dialog_selection_callback): Likewise.
12228 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12229 Also, don't assume VALBITS / RAND_BITS is less than 5,
12230 and don't rely on undefined behavior when shifting a 1 left into
12232 * lisp.h (get_random): Change signature to match.
12234 * lread.c (hash_string): Use size_t, not int, for hash computation.
12235 Normally we prefer signed values; but hashing is special, because
12236 it's better to use unsigned division on hash table sizes so that
12237 the remainder is nonnegative. Also, size_t is the natural width
12238 for hashing into memory. The previous code used 'int', which doesn't
12239 retain enough info to hash well into very large tables.
12240 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12242 * dbusbind.c: Don't possibly lose pointer info when converting.
12243 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12244 Use XPNTR rather than XHASH, so that the high-order bits of
12245 the pointer aren't lost when converting through void *.
12247 * eval.c (Fautoload): Don't double-shift a pointer.
12249 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

12283 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12284 Remove unused parameter `fildes'.
12285 * process.c (read_process_output, send_process): Don't pass it.
12287 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12289 Fix previous change: the library cache is defined in w32.c.
12290 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12291 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

12326 (w32_delayed_load): Move from image.c. When loading a library, record
12327 its filename in the :loaded-from property of the library id.

12333 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12334 instead of gnutls_record_check_pending.
12336 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12338 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12340 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12341 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12344 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12346 * xterm.c (x_set_frame_alpha): Do not set property on anything

12376 which is like wait_for_termination, but allows keyboard
12379 * callproc.c (Fcall_process): Add (:file "file") as an option for
12381 (Fcall_process_region): Ditto.
12383 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12385 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12386 rather than `XVECTOR (FOO)->size'.
12388 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12389 inttypes.h, as a gnulib replacement is used if it not available in
12392 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12394 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12395 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12396 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12398 * coding.c (coding_alloc_by_realloc): Error out if destination
12399 will grow beyond MOST_POSITIVE_FIXNUM.
12400 (decode_coding_emacs_mule): Abort if there isn't enough place in
12401 charbuf for the composition carryover bytes. Reserve an extra
12402 space for up to 2 characters produced in a loop.

12404 charbuf for the composition carryover bytes.
12406 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12408 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12409 aborting when %lld or %lll format is passed.

12417 produced by %s or %c overflows available buffer space. (Bug#8545)
12419 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12421 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

12433 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12434 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12436 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12438 * doprnt.c (doprnt): Don't return value smaller than the buffer
12439 size if the message was truncated. (Bug#8545).
12441 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12443 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

12450 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12452 * makefile.w32-in: Update dependencies.
12454 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12456 Improve `doprnt' and its usage. (Bug#8545)
12457 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12458 `format_end'. Remove support for %l as a conversion specifier.
12459 Don't use xrealloc. Improve diagnostics when the %l size modifier
12460 is used. Update the commentary.
12462 * eval.c (verror): Simplify calculation of size_t.
12464 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12467 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12469 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12472 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12474 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12475 This makes this file independent of the recent pseudovector change.
12477 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12479 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12481 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12482 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12483 Remove unused local.
12484 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12486 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12487 GCC 4.6.0 optimizes based on type-based alias analysis.
12488 For example, if b is of type struct buffer * and v of type struct
12489 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12490 != &v->size, and therefore "v->size = 1; b->size = 2; return
12491 v->size;" must therefore return 1. This assumption is incorrect
12492 for Emacs, since it type-puns struct Lisp_Vector * with many other
12493 types. To fix this problem, this patch adds a new type struct
12494 vectorlike_header that documents the constraints on layout of vectors
12495 and pseudovectors, and helps optimizing compilers not get fooled
12496 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12497 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12498 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12500 (XSETPVECTYPE): Rewrite in terms of new macro.
12501 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12502 This is a bit clearer, and further avoids the possibility of
12503 undesirable aliasing.
12504 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12505 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12506 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12507 since Lisp_Subr is a special case (no "next" field).
12508 (ASIZE): Now uses header.size rather than size.
12509 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12510 to avoid the hassle of writing XVECTOR (foo)->header.size.
12511 (struct vectorlike_header): New type.
12512 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12513 object, to help avoid aliasing.
12514 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12515 (SUBRP): Likewise, since Lisp_Subr is a special case.
12516 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12517 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12518 (struct Lisp_Hash_Table): Combine first two members into a single
12519 struct vectorlike_header member. All uses of "size" and "next" members
12520 changed to be "header.size" and "header.next".
12521 * buffer.h (struct buffer): Likewise.
12522 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12523 * frame.h (struct frame): Likewise.
12524 * process.h (struct Lisp_Process): Likewise.
12525 * termhooks.h (struct terminal): Likewise.
12526 * window.c (struct save_window_data, struct saved_window): Likewise.
12527 * window.h (struct window): Likewise.
12528 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12529 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12530 * buffer.c (init_buffer_once): Likewise.
12531 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12533 * process.c (Fformat_network_address): Use local var for size,
12536 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12538 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12539 * data.c (atof): Remove decl; no longer used or needed.
12540 (digit_to_number): Move to lread.c.
12541 (Fstring_to_number): Use new string_to_number function, to be
12542 consistent with how the Lisp reader treats infinities and NaNs.
12543 Do not assume that floating-point numbers represent EMACS_INT
12544 without losing information; this is not true on most 64-bit hosts.
12545 Avoid double-rounding errors, by insisting on integers when
12546 parsing non-base-10 numbers, as the documentation specifies.
12547 * lisp.h (string_to_number): New decl, replacing ...
12548 (isfloat_string): Remove.
12549 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12550 (read1): Do not accept +. and -. as integers; this
12551 appears to have been a coding error. Similarly, do not accept
12552 strings like +-1e0 as floating point numbers. Do not report
12553 overflow for integer overflows unless the base is not 10 which
12554 means we have no simple and reliable way to continue.
12555 Break out the floating-point parsing into a new
12556 function string_to_number, so that Fstring_to_number parses
12557 floating point numbers consistently with the Lisp reader.
12558 (digit_to_number): Move here from data.c. Make it static inline.
12559 (E_CHAR, EXP_INT): Remove, replacing with ...
12560 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12561 (string_to_number): New function, replacing isfloat_string.
12562 This function checks for valid syntax and produces the resulting
12563 Lisp float number too. Rework it so that string-to-number
12564 no longer mishandles examples like "1.0e+". Use strtoumax,
12565 so that overflow for non-base-10 numbers is reported only when
12566 there's no portable and simple way to convert to floating point.
12568 * textprop.c (set_text_properties_1): Rewrite for clarity,
12569 and to avoid GCC warning about integer overflow.
12571 * intervals.h (struct interval): Use EMACS_INT for members
12572 where EMACS_UINT might cause problems. See
12573 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12574 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12575 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12577 (offset_intervals): Tell GCC not to worry about length overflow
12578 when negating a negative length.
12580 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12581 (overrun_check_free): Likewise.
12583 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12584 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12587 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12588 (gnutls_make_error): Rename local to avoid shadowing.
12589 (gnutls_emacs_global_deinit): ifdef out; not used.
12590 (Fgnutls_boot): Use const for pointer to readonly storage.
12591 Comment out unused local. Fix pointer signedness problems.
12593 * lread.c (openp): Don't stuff size_t into an 'int'.
12594 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12595 about possible signed overflow.
12597 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12598 (GDK_KEY_g): Don't define if already defined.
12599 (xg_prepare_tooltip): Avoid pointer signedness problem.
12600 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12602 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12603 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12605 * xfns.c (Fx_window_property): Simplify a bit,
12606 to make a bit faster and to avoid GCC 4.6.0 warning.
12607 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12609 * fns.c (internal_equal): Don't assume size_t fits in int.
12611 * alloc.c (compact_small_strings): Tighten assertion a little.
12613 Replace pEd with more-general pI, and fix some printf arg casts.
12614 * lisp.h (pI): New macro, generalizing old pEd macro to other
12615 conversion specifiers. For example, use "...%"pI"d..." rather
12616 than "...%"pEd"...".
12617 (pEd): Remove. All uses replaced with similar uses of pI.
12618 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12619 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12620 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12621 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12622 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12623 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12624 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12626 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12627 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12628 * print.c (safe_debug_print, print_object): Likewise.
12629 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12631 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12632 avoiding the 0 flag, which is not portable.
12633 * process.c (Fmake_network_process): Use pI to avoid cast.
12634 * region-cache.c (pp_cache): Likewise.
12635 * xdisp.c (decode_mode_spec): Likewise.
12636 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12637 behavior on 64-bit hosts with printf arg.

12639 (x_stop_queuing_selection_requests): Likewise.
12640 (x_get_window_property): Don't truncate byte count to an 'int'
12643 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12644 here, since it parses constructs like leading '-' and spaces,
12645 which are not wanted; and it overflows with large numbers.
12646 Instead, simply match F[0-9]+, which is what is wanted anyway.
12648 * alloc.c: Remove unportable assumptions about struct layout.
12649 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12650 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12651 (allocate_vectorlike, make_pure_vector): Use the new macros,
12652 plus offsetof, to remove unportable assumptions about struct layout.
12653 These assumptions hold on all porting targets that I know of, but
12654 they are not guaranteed, they're easy to remove, and removing them
12655 makes further changes easier.
12657 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12658 This doesn't fix a bug but makes the code clearer.
12659 (string_overrun_cookie): Now const. Use initializers that
12660 don't formally overflow signed char, to avoid warnings.
12661 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12662 can cause Emacs to crash when string overrun checking is enabled.
12663 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12664 multiple of sizeof (EMACS_INT); it need not be, if
12665 alignof(EMACS_INT) < sizeof (EMACS_INT).
12666 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12668 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12695 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12697 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12698 "cast to pointer from integer of different size".
12700 Improve doprnt and its use in verror. (Bug#8545)
12701 * doprnt.c (doprnt): Document the set of format control sequences
12702 supported by the function. Use SAFE_ALLOCA instead of always
12705 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12706 is one byte too soon. Don't use xrealloc; instead xfree and
12709 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12711 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

12718 docstring. Start callback support.
12719 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12720 unless a fatal error occurred. Call gnutls_alert_send_appropriate

12824 codepoint of an invalid character, to avoid displaying a bogus
12827 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12828 `error', not SYMBOL_NAME itself.
12830 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12831 character arguments to `error'.
12833 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12834 to `error' in error message about FINAL_CHAR argument. Make sure
12835 FINAL_CHAR is a character, and use %c when it is passed as
12836 argument to `error'.
12838 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12840 * s/ms-w32.h (localtime): Redirect to sys_localtime.
12842 * w32.c: Include <time.h>.

12904 * xfaces.c (USG, __TIMEVAL__): Likewise.
12906 * dispextern.h (struct redisplay_interface): Rename param
12907 to avoid shadowing.
12908 * termhooks.h (struct terminal): Likewise.
12909 * xterm.c (xembed_send_message): Likewise.

13025 * nsfont.m: Fixed bugs in ns_get_family and
13026 ns_descriptor_to_entity that were caused by using free to
13027 deallocate memory blocks that were allocated by xmalloc (via
13028 xstrdup). This caused Emacs to crash when compiled with
13029 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13030 --enable-checking=xmallocoverrun). xfree is now used to
13031 deallocate these memory blocks.

13045 (emacs_read, emacs_write): Remove check for negative size, as the
13046 Emacs source code has been audited now.
13047 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
13048 (emacs_read, emacs_write): Use it.
13049 * process.c (send_process): Adjust to the new signatures of
13050 emacs_write and emacs_gnutls_write. Do not attempt to store
13051 a byte offset into an 'int'; it might overflow.
13052 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

13512 * xsettings.c (read_and_apply_settings): Likewise.
13514 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13515 (overrun_check_free): Protoize.
13517 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13519 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13520 since callers should never pass a negative size.
13521 Change the signature to match that of plain 'read' and 'write'; see
13522 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13523 * lisp.h: Update prototypes of emacs_write and emacs_read.
13525 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13527 * xdisp.c (redisplay_window): Don't try to determine the character
13528 position of the scroll margin if the window start point w->startp
13529 is outside the buffer's accessible region. (Bug#8468)
13531 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13533 Fix write-region and its subroutines for buffers > 2GB.
13534 * fileio.c (a_write, e_write): Modify declaration of arguments and
13535 local variables to support buffers larger than 2GB.
13536 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13538 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13539 argument, local variables, and return value.
13541 * lisp.h: Update prototypes of emacs_write and emacs_read.
13543 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13545 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13547 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13549 Fix more problems found by GCC 4.6.0's static checks.
13551 * xdisp.c (vmessage): Use a better test for character truncation.
13553 * charset.c (load_charset_map): <, not <=, for optimization,
13554 and to avoid potential problems with integer overflow.
13555 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13556 * casetab.c (set_identity, shuffle): Likewise.
13557 * editfns.c (Fformat): Likewise.
13558 * syntax.c (skip_chars): Likewise.
13560 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13561 This also lets GCC 4.6.0 generate slightly better loop code.
13563 * callint.c (Fcall_interactively): <, not <=, for optimization.
13564 (Fcall_interactively): Count the number of arguments produced,
13565 not the number of arguments given. This is simpler and lets GCC
13566 4.6.0 generate slightly better code.
13568 * ftfont.c: Distingish more carefully between FcChar8 and char.
13569 The previous code passed unsigned char * to a functions like
13570 strlen and xstrcasecmp that expect char *, which does not
13571 conform to the C standard.
13572 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13573 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13574 char * when the C standard requires it.
13576 * keyboard.c (read_char): Remove unused var.
13578 * eval.c: Port to Windows vsnprintf (Bug#8435).
13579 Include <limits.h>.
13580 (SIZE_MAX): Define if the headers do not.
13581 (verror): Do not give up if vsnprintf returns a negative count.
13582 Instead, grow the buffer. This ports to Windows vsnprintf, which
13583 does not conform to C99. Problem reported by Eli Zaretskii.
13584 Also, simplify the allocation scheme, by avoiding the need for
13585 calling realloc, and removing the ALLOCATED variable.
13587 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13589 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13590 But keep the doprint source code for now, as we might revamp it
13591 and use it again (Bug#8435).
13592 * lisp.h (doprnt): Remove.
13593 * Makefile.in (base_obj): Remove doprnt.o.
13594 * deps.mk (doprnt.o): Remove.
13596 error: Print 32- and 64-bit integers portably (Bug#8435).
13597 Without this change, on typical 64-bit hosts error ("...%d...", N)
13598 was used to print both 32- and 64-bit integers N, which relied on
13599 undefined behavior.
13600 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13601 * lisp.h (error, verror): Mark as printf-like functions.
13602 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13603 Report overflow in size calculations when allocating printf buffer.
13604 Do not truncate output string at its first null byte.
13605 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13606 Truncate the output at a character boundary, since vsnprintf does not
13608 * charset.c (check_iso_charset_parameter): Convert internal
13609 character to string before calling 'error', since %c now has the
13611 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13612 overflow when computing char to be passed to 'error'. Do not
13613 pass Lisp_Object to 'error'; pass the integer instead.
13614 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13615 formatted with plain %d.
13617 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13619 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13621 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13623 * xterm.c (x_catch_errors): Remove duplicate declaration.
13625 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13627 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13629 2011-04-10 Jim Meyering <meyering@redhat.com>
13631 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13632 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13633 return ssize_t not "int", and use size_t as the buffer length.
13634 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13635 * gnutls.h: Update declarations.
13636 * process.c (read_process_output): Use ssize_t, to match.
13637 (send_process): Likewise.
13639 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13641 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13643 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13645 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13646 Use unsigned char, to match FcChar8 type definition.
13648 * xterm.c (handle_one_xevent):
13649 * xmenu.c (create_and_show_popup_menu):
13650 * xselect.c (x_decline_selection_request)
13651 (x_reply_selection_request): Avoid type-punned deref of X events.
13653 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13655 Fix some uses of `int' instead of EMACS_INT.
13656 * search.c (string_match_1, fast_string_match)
13657 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13658 (scan_buffer, find_next_newline_no_quit)
13659 (find_before_next_newline, search_command, Freplace_match)
13660 (Fmatch_data): Make some `int' variables be EMACS_INT.
13662 * xdisp.c (display_count_lines): 3rd argument and return value now
13663 EMACS_INT. All callers changed.
13664 (pint2hrstr): Last argument is now EMACS_INT.
13666 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13667 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13668 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13669 (decode_coding_utf_16, decode_coding_emacs_mule)
13670 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13671 (decode_coding_ccl, decode_coding_charset)
13672 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13673 (decode_coding_iso_2022, decode_coding_emacs_mule)
13674 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13675 <char_offset, last_offset>: Declare EMACS_INT.
13676 (encode_coding_utf_8, encode_coding_utf_16)
13677 (encode_coding_emacs_mule, encode_invocation_designation)
13678 (encode_designation_at_bol, encode_coding_iso_2022)
13679 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13680 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13682 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13683 (encode_invocation_designation): Last argument P_NCHARS is now
13685 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13686 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13688 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13691 * ccl.c (Fccl_execute_on_string): Declare some variables
13694 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13696 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13698 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13700 * process.c (Fformat_network_address): Doc fix.
13702 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13704 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13706 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13708 * keyboard.c (read_char): Call Lisp function help-form-show,
13709 instead of using internal_with_output_to_temp_buffer.
13710 (Qhelp_form_show): New var.
13711 (syms_of_keyboard): Use DEFSYM macro.
13713 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13715 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13717 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13719 * process.c (Flist_processes): Remove to Lisp.
13720 (list_processes_1): Delete.

13726 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13728 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13730 Fix more problems found by GCC 4.6.0's static checks.

13734 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13736 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13738 * xdisp.c (vmessage): Mark as a printf-like function.
13740 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13742 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13744 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13745 printf-like functions.
13746 (tiff_load): Add casts to remove these marks before passing them
13747 to system-supplied API.
13749 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13751 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13752 This avoids several warnings with gcc -Wstrict-overflow.
13753 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13754 directly, rather than having caller test rule sign. This avoids
13755 some unnecessary tests.
13756 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13757 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13758 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13760 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13761 (xfont_open): Avoid unnecessary tests.
13763 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13765 * composite.h, composite.c (composition_gstring_put_cache):
13766 Use EMACS_INT, not int, for length.

13772 by using the new macro.
13774 * textprop.c (set_text_properties_1): Change while to do-while,
13775 since the condition is always true at first.
13777 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13778 (interval_deletion_adjustment): Return unsigned value.
13781 * process.c (list_processes_1, create_pty, read_process_output):

13793 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13794 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13795 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13797 * print.c (print_error_message): Avoid int overflow.
13799 * font.c (font_list_entities): Redo for clarity,
13800 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13802 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13803 (font_score): Avoid potential overflow in diff calculation.
13805 * fns.c (substring_both): Remove var that is set but not used.
13806 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13808 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13810 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13811 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13812 can always succeed if overflow has undefined behavior.
13814 * search.c (boyer_moore, wordify): Remove vars set but not used.
13815 (wordify): Omit three unnecessary tests.
13817 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13818 All callers changed. This avoids the need for an unused var.
13820 * casefiddle.c (casify_region): Remove var that is set but not used.
13822 * dired.c (file_name_completion): Remove var that is set but not used.
13824 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13826 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13827 (Finsert_file_contents): Remove unnecessary code checking fd.
13829 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13830 Check for integer overflow on size calculations.
13832 * buffer.c (Fprevious_overlay_change): Remove var that is set
13835 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13836 Remove vars that are set but not used.
13837 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13838 (timer_check_2): Mark vars as initialized.
13840 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13842 * image.c (lookup_image): Remove var that is set but not used.
13843 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13845 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13846 that are set but not used.
13848 * xfns.c (make_invisible_cursor): Don't return garbage
13849 if XCreateBitmapFromData fails (Bug#8410).
13851 * xselect.c (x_get_local_selection, x_handle_property_notify):
13852 Remove vars that are set but not used.
13854 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

13864 (map_tty_color) [!defined MSDOS]: Likewise.
13866 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13868 * coding.c: Remove vars that are set but not used.
13869 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13870 All callers changed.
13871 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13872 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13873 (decode_coding_charset): Remove vars that are set but not used.
13875 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13876 that is set but not used.
13878 * print.c (print_object): Remove var that is set but not used.
13880 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13881 The gnulib version avoids calling malloc in the usual case,
13882 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13883 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13884 * filelock.c (current_lock_owner): Likewise.
13885 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

13888 (emacs_readlink): New function.
13889 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13890 ../lib/careadlinkat.h.
13892 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13894 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13895 first non-nil return value).

13904 * xdisp.c (display_count_lines): Remove parameter `start',
13905 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

13909 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13910 and thereabouts. All callers changed.
13911 (get_per_char_metric): Remove parameter `f', unused since
13912 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13960 (Feval): New `lexical' arg.
13961 (eval_sub): New function extracted from Feval. Use it almost

13969 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13970 but without exporting it to Lisp.
13972 * doc.c (Fdocumentation, store_function_docstring):
13973 * data.c (Finteractive_form): Handle closures.
13975 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13978 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13980 (exec_byte_code): New function extracted from Fbyte_code to handle new
13981 calling convention for byte-code-functions. Add new byte-codes.
13983 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13985 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13987 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13989 * xdisp.c (redisplay_internal): Fix prototype.
13991 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13993 * xdisp.c (SCROLL_LIMIT): New macro.
13994 (try_scrolling): Use it when setting scroll_limit.
13995 Limit scrolling to 100 screen lines.
13996 (redisplay_window): Even when falling back on "recentering",
13997 position point in the window according to scroll-conservatively,
13998 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14000 (try_scrolling): When point is above the window, allow searching
14001 as far as scroll_max, or one screenful, to compute vertical
14002 distance from PT to the scroll margin position. This prevents
14003 try_scrolling from unnecessarily failing when
14004 scroll-conservatively is set to a value slightly larger than the
14005 window height. Clean up the case of PT below the margin at bottom
14006 of window: scroll_max can no longer be INT_MAX. When aggressive
14007 scrolling is in use, don't let point enter the opposite scroll
14008 margin as result of the scroll.
14009 (syms_of_xdisp) <scroll-conservatively>: Document the
14010 threshold of 100 lines for never-recentering scrolling.
14012 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14014 * dispextern.h (move_it_by_lines):
14015 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14016 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14017 (message_log_check_duplicate): Remove parameters `prev_bol' and
14018 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14019 (redisplay_internal): Remove parameter `preserve_echo_area',
14020 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14022 * indent.c (Fvertical_motion):
14023 * window.c (window_scroll_pixel_based, Frecenter):
14024 Don't pass `need_y_p' to `move_it_by_lines'.
14026 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14028 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14029 steal a few bits to be more compact.
14030 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14031 Remove unneeded casts.
14033 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14035 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14037 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14038 binding" message (bug#7967).
14040 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14042 Fix more problems found by GCC 4.6.0's static checks.
14044 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14045 Remove unused local var.
14047 * editfns.c (Fmessage_box): Remove unused local var.
14049 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14050 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14051 Omit unused local vars.
14052 * window.c (shrink_windows): Omit unused local var.
14053 * menu.c (digest_single_submenu): Omit unused local var.
14054 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14055 Omit unused local var.
14057 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14058 Don't assume string length fits in int.
14059 (keyremap_step, read_key_sequence): Use size_t for sizes.
14060 (read_key_sequence): Don't check last_real_key_start redundantly.
14062 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14063 instead of alloca (Bug#8344).
14065 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14066 (Fbacktrace_frame): Don't assume nframes fits in int.
14068 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14070 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14073 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14075 * cm.c (calccost): Turn while-do into do-while, for clarity.
14077 * keyboard.c (syms_of_keyboard): Use the same style as later
14078 in this function when indexing through an array. This also
14079 works around GCC bug 48267.
14081 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14083 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14085 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14086 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14088 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14089 This avoids undefined behavior on integer overflow, and is a bit
14090 more convenient anyway since it is compared to a size_t variable.
14092 Variadic C functions now count arguments with size_t, not int.
14093 This avoids an unnecessary limitation on 64-bit machines, which
14094 caused (substring ...) to crash on large vectors (Bug#8344).
14095 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14096 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14097 All variadic functions and their callers changed accordingly.
14098 (struct gcpro.nvars): Now size_t, not int. All uses changed.

14100 * editfns.c (general_insert_function): Likewise.
14101 * eval.c (struct backtrace.nargs, interactive_p)
14102 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14103 (funcall_lambda, mark_backtrace): Likewise.
14104 * fns.c (concat): Likewise.
14105 * frame.c (x_set_frame_parameters): Likewise.
14106 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14107 0 if not found, not -1. All callers changed.
14109 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14110 (stack_copy_size): Now size_t, not int.
14111 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14113 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14115 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14116 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14117 All callers changed.
14119 * lisp.h (multibyte_char_to_unibyte):
14120 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14121 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14122 * character.h (CHAR_TO_BYTE8):
14123 * cmds.c (internal_self_insert):
14124 * editfns.c (general_insert_function):
14125 * keymap.c (push_key_description):
14126 * search.c (Freplace_match):
14127 * xdisp.c (message_dolog, set_message_1): All callers changed.
14129 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14131 * keyboard.c (safe_run_hook_funcall): New function.
14132 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14133 don't set the hook to nil, but remove the offending function instead.
14134 (Qcommand_hook_internal): Remove, unused.
14135 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14136 Vcommand_hook_internal.
14138 * eval.c (enum run_hooks_condition): Remove.
14139 (funcall_nil, funcall_not): New functions.
14140 (run_hook_with_args): Call each function through a `funcall' argument.
14141 Remove `cond' argument, now redundant.
14142 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14143 (Frun_hook_with_args_until_failure): Adjust accordingly.
14144 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14146 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14148 * dispextern.h (string_buffer_position): Remove declaration.
14150 * print.c (strout): Remove parameter `multibyte', unused since
14151 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14153 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14154 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14155 All callers changed.
14157 * w32.c (_wsa_errlist): Use braces for struct initializers.
14159 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14160 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14161 All callers changed.
14162 (string_buffer_position): Likewise. Also, make static (it's never
14163 used outside xdisp.c).
14164 (cursor_row_p): Remove parameter `w', unused since
14165 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14167 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14168 All callers changed.
14170 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14172 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14177 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
14178 (ns_update_auto_hide_menu_bar): New functions.
14179 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

14183 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14185 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14187 * nsmenu.m (runDialogAt): Remove argument to timer_check.
14189 2011-03-27 Glenn Morris <rgm@gnu.org>
14191 * syssignal.h: Replace RETSIGTYPE with void.
14192 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
14193 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
14194 Replace SIGTYPE with void everywhere.
14195 * s/usg5-4-common.h (SIGTYPE): Remove definition.
14196 * s/template.h (SIGTYPE): Remove commented out definition.
14198 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14200 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14201 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14203 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14205 * w32.c (read_unc_volume): Use parameter `henum', instead of
14206 global variable `wget_enum_handle'.
14208 * keymap.c (describe_vector): Remove parameters `indices' and
14209 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14212 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
14214 * keyboard.c (timer_check): Remove parameter `do_it_now',
14215 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
14216 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
14217 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
14219 * keyboard.c (read_char):
14220 * w32menu.c (w32_menu_display_help):
14221 * xmenu.c (show_help_event, menu_help_callback):
14222 Adjust calls to `show_help_echo'.
14224 * gtkutil.c (xg_maybe_add_timer):
14225 * keyboard.c (readable_events):
14226 * process.c (wait_reading_process_output):
14227 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14229 * insdel.c (adjust_markers_gap_motion):
14230 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
14231 (gap_left, gap_right): Don't call it.
14233 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

14277 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
14279 * w32term.c (x_set_glyph_string_clipping):
14280 Don't pass uninitialized region to CombineRgn.
14282 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
14284 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
14285 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
14286 (Fx_close_connection): Remove unused variable `i'.
14288 * w32font.c (w32font_draw): Return number of glyphs.
14289 (w32font_open_internal): Remove unused variable `i'.

14302 (uniscribe_font_driver): Add missing initializers.
14304 2011-03-23 Julien Danjou <julien@danjou.info>
14306 * term.c (Fsuspend_tty, Fresume_tty):
14307 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14308 * window.c (temp_output_buffer_show):
14309 * insdel.c (signal_before_change):
14310 * frame.c (Fhandle_switch_frame):
14311 * fileio.c (Fdo_auto_save):
14312 * emacs.c (Fkill_emacs):
14313 * editfns.c (save_excursion_restore):
14314 * cmds.c (internal_self_insert):
14315 * callint.c (Fcall_interactively):
14316 * buffer.c (Fkill_all_local_variables):
14317 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14319 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14320 unconditionally since it does the check itself.
14322 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14324 Fix more problems found by GCC 4.5.2's static checks.
14326 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14327 the first time through the loop, since we know p0 < p1 then.
14328 This also avoids a gcc -Wstrict-overflow warning.
14330 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14331 leading to a memory leak, possible in functions like
14332 load_charset_map_from_file that can allocate an unbounded number
14333 of objects (Bug#8318).
14335 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14336 that could (at least in theory) be that large.
14338 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14339 This is less likely to overflow, and avoids undefined behavior if
14340 overflow does occur. All callers changed. Use strtoul to scan
14341 for the unsigned long integer.
14342 (pint2hrstr): Simplify and tune code slightly.
14343 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14345 * scroll.c (do_scrolling): Work around GCC bug 48228.
14346 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
14348 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
14349 This also avoids a warning with gcc -Wstrict-overflow.
14350 (validate_x_resource_name): Simplify count usage.
14351 This also avoids a warning with gcc -Wstrict-overflow.
14353 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14356 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14358 * process.c (Fmake_network_process): Use socklen_t, not int,
14359 where POSIX says socklen_t is required in portable programs.
14360 This fixes a porting bug on hosts like 64-bit HP-UX, where
14361 socklen_t is wider than int (Bug#8277).
14362 (Fmake_network_process, server_accept_connection):
14363 (wait_reading_process_output, read_process_output):
14366 * process.c: Rename or move locals to avoid shadowing.
14367 (list_processes_1, Fmake_network_process):
14368 (read_process_output_error_handler, exec_sentinel_error_handler):
14369 Rename or move locals.
14370 (Fmake_network_process): Define label "retry_connect" only if needed.
14371 (Fnetwork_interface_info): Fix pointer signedness.
14372 (process_send_signal): Add cast to avoid pointer signedness problem.
14373 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14374 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14376 Make tparam.h and terminfo.c consistent.
14377 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14378 Include tparam.h instead, since it declares them.
14379 * cm.h (PC): Remove extern decl; tparam.h now does this.
14380 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14381 * terminfo.c: Include tparam.h, to check interfaces.
14382 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14383 (tparam): Adjust signature to match interface in tparam.h;
14384 this removes some undefined behavior. Check that outstring and len
14385 are zero, which they always are with Emacs.
14386 * tparam.h (PC, BC, UP): New extern decls.
14388 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14389 (xftfont_open): Rename locals to avoid shadowing.
14391 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14392 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14393 (OTF_TAG_SYM): Omit macro if not needed.
14394 (ftfont_list): Remove unused local.
14395 (get_adstyle_property, ftfont_pattern_entity):
14396 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14397 Rename locals to avoid shadowing.
14399 * xfont.c (xfont_list_family): Mark var as initialized.
14401 * xml.c (make_dom): Now static.

14440 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14442 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14443 This should get cleaned up, so that child_setup has the
14444 same signature on all platforms.
14446 * callproc.c (call_process_cleanup): Now static.
14447 (relocate_fd): Rename locals to avoid shadowing.

14608 (Fmemory_limit): Cast sbrk's returned value to char *.
14610 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14616 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14617 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14618 to use the following functions instead of these macros.
14619 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14620 EMACS_INT, since callers assume the returned value fits in int.
14621 (upcase1): Likewise, for UPCASE_TABLE.
14622 (uppercasep, lowercasep, upcase): New static inline functions.
14623 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14633 (regex_compile, re_match_2_internal): Mark locals as initialized.
14634 (RETALLOC_IF): Define only if needed.
14635 (WORDCHAR_P): Likewise. This one is never needed, but is used
14636 only in a comment talking about a compiler bug, so put inside
14637 the #if 0 of that comment.
14638 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14639 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14666 New macros, so that the caller can use some names other than
14667 gcpro1, gcpro2, etc.
14668 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14670 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14671 argument, for consistency with GCPRO2_VAR, etc: it is now the
14672 prefix of the variable, not the variable itself. All uses
14674 * dired.c (directory_files_internal, file_name_completion):
14675 Rename locals to avoid shadowing.
14677 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14678 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14679 dired.c's scmp function, had undefined behavior.
14680 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14681 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14682 * buffer.h: ... to here, because these macros use current_buffer,
14683 and the new implementation with inline functions needs to have
14684 current_buffer in scope now, rather than later when the macros
14686 (downcase, upcase1): New static inline functions.
14687 (DOWNCASE, UPCASE1): Reimplement using these functions.
14688 This avoids undefined behavior in expressions like
14689 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14690 from race conditions in accessing the global variables
14691 case_temp1 and case_temp2.
14692 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14693 * lisp.h (case_temp1, case_temp2): Remove their decls.
14694 * character.h (ASCII_CHAR_P): Move from here ...
14695 * lisp.h: ... to here, so that the inline functions mentioned
14696 above can use them.
14698 * dired.c (directory_files_internal_unwind): Now static.
14700 * fileio.c (file_name_as_directory, directory_file_name):

14703 (file_name_as_directory): Use const pointers when appropriate.
14704 (Fexpand_file_name): Likewise. In particular, newdir might
14705 point at constant storage, so make it a const pointer.
14706 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14707 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14709 (Fset_file_times, Finsert_file_contents, auto_save_error):

14714 to avoid shadowing.
14716 * marker.c (bytepos_to_charpos): Remove; unused.
14718 * lisp.h (verify_bytepos, count_markers): New decls,
14719 so that gcc does not warn that these functions aren't declared.
14721 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14722 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14723 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14724 (copy_text): Remove unused local var.

14729 * buffer.c (fix_overlays_before): Mark locals as initialized.
14730 (fix_start_end_in_overlays): Likewise. This function should be
14731 simplified by using pointers-to-pointers, but that's a different
14733 (switch_to_buffer_1): Now static.
14734 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14735 (report_overlay_modification): Rename locals to avoid shadowing.

14738 Fix pointer signedness issue.
14739 (sys_subshell): Mark local as volatile if checking for lint,
14740 to suppress a gcc -Wclobbered warning that does not seem to be right.
14741 (MAXPATHLEN): Define only if needed.
14743 * process.c (serial_open, serial_configure): Move decls from here ...
14744 * systty.h: ... to here, so that they can be checked.
14746 * fns.c (get_random, seed_random): Move extern decls from here ...
14747 * lisp.h: ... to here, so that they can be checked.
14749 * sysdep.c (reset_io): Now static.

14757 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14758 (describe_map_tree):
14759 Rename locals to avoid shadowing.
14761 * keyboard.c: Declare functions static if they are not used elsewhere.
