3 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
4 try to get accurate owner and group information from NT file
5 security APIs. This is to make most callers of 'stat' and
6 'lstat', which don't need that information, much faster.
8 * dired.c (Ffile_attributes) [WINDOWSNT]: Set
9 w32_stat_get_owner_group to a non-zero value, to request accurate
10 owner and group information from 'lstat'.
12 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
14 * fileio.c (Finsert_file_contents): Don't put tail into head area,
15 as that confuses set-auto-coding, so insist on the head-read
16 returning the full 1024 bytes. Let lseek compute the tail offset;
17 less work for us. Do not ignore I/O errors when reading the tail.
19 * xdisp.c: Minor style fixes.
20 (init_iterator): Hoist assignment out of if-expression.
21 (markpos_of_region): Callers now test for sign, not for -1.
23 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
25 Minor redisplay optimization when the region length is zero.
26 * xdisp.c (markpos_of_region): New function.
27 (init_iterator): Do not highlight the region of zero length.
28 (redisplay_window): Check whether the region is of non-zero length.
29 (try_cursor_movement): Allow if the region length is zero.
30 (try_window_reusing_current_matrix, try_window_id): Likewise.

42 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
44 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
46 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
47 fstat shouldn't fail, and if it does fail copy-file should not proceed.
48 Remove unnecessary S_ISLNK test, as (contra the comments) this
49 function can't copy symlinks. Improve quality of error message
50 when attempting to copy files that are neither regular files nor
53 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>

61 2012-12-12 Daniel Colascione <dancol@dancol.org>
63 * unexcw.c (fixup_executable): use posix_fallocate to ensure that
64 the dumped Emacs is not a sparse file, greatly improving Cygwin
65 "make bootstrap" performance.
67 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
69 * inotify.c (inotify_callback): Generate an Emacs event for every
70 incoming inotify event.
72 2012-12-11 Eli Zaretskii <eliz@gnu.org>
74 * xdisp.c (handle_face_prop): Fix logic of computing
75 it->start_of_box_run_p.
76 (append_space_for_newline): If the glyph row is R2L, reset the
77 iterator's end_of_box_run_p flag before prepending the space glyph.
78 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
79 iterator's start_of_box_run_p flag before prepending the stretch.
80 (append_glyph, produce_image_glyph, append_composite_glyph)
81 (append_stretch_glyph, append_glyphless_glyph): Reverse the
82 left_box_line_p and right_box_line_p flags of the glyph for R2L
83 glyph rows. (Bug#13011)
85 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
87 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
88 if changed buffer is not shown in a window.

90 * window.c (replace_buffer_in_windows_safely): Do nothing
91 if buffer is not shown in a window.
92 (Fforce_window_update): Likewise if string or buffer argument
95 2012-12-11 Eli Zaretskii <eliz@gnu.org>
97 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
98 encoded_file_name, which is what it is.
100 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
102 Consistently use marker_position and marker_byte_position.
103 * fringe.c (Ffringe_bitmaps_at_pos):

105 * insdel.c (prepare_to_modify_buffer):
106 * keyboard.c (make_lispy_position):

117 * makefile.w32-in (SIG2STR_H): New macro.
118 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
119 ($(BLD)/w32notify.$(O)): Update dependencies.
121 2012-12-10 Daniel Colascione <dancol@dancol.org>
123 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
124 Windows file notification functionality unless WINDOWSNT.
126 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
129 * w32fns.c (cache_system_info): Initialize the global hinst
130 variable here so various initialization calls DTRT.
132 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused
134 (hinst): Remove unneeded extern declaration.
135 (_start): Remove initialization of above variables; remove
136 initialization of hinst, as cache_system_info now does that.
138 * emacs.c (main): Call cache_system_info early in startup; we
139 previously weren't calling it in Cygwin builds.
141 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK): Teach
142 the autoconf build system how to compile a Windows resource file
143 and link it to Emacs.

166 2012-12-10 Eli Zaretskii <eliz@gnu.org>
168 Support for filesystem notifications on MS-Windows.
169 * w32proc.c (sys_select): If drain_message_queue returns non-zero,
170 and this is a TTY frame, signal the caller that keyboard input is
173 * w32xfns.c (drain_message_queue): Now returns an int: an
174 indication whether any WM_EMACS_FILENOTIFY messages were found in
177 * w32inevt.c (handle_file_notifications): New function.

266 displayed on the left or the right margin, don't consider it as a
267 factor in cursor positioning. (Bug#13108)
269 2012-12-10 Martin Rudalics <rudalics@gmx.at>
271 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
273 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

278 2012-12-08 Eli Zaretskii <eliz@gnu.org>
280 * w32.c (unsetenv): Return 0 if the input string is too long.
282 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
284 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
285 * alloc.c (xputenv): New function.
286 * dbusbind.c (Fdbus_init_bus):
288 * xterm.c (x_term_init):
289 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
290 * editfns.c (initial_tz): Move static var decl up.

294 Save old TZ value on stack, if it's small.
295 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
296 instead, use xputenv+unsetenv to set and restore TZ.
297 (environbuf): Remove static var. All uses removed.
298 (Fset_time_zone_rule): Do not save TZ and environ;
299 no longer needed here.
300 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
301 Move to inside set_time_zone_rule; they don't need file scope any more.
302 (set_time_zone_rule): Maintain the TZ=value string separately.
303 (syms_of_editfns): Don't initialize initial_tz;
304 init_editfns now does it.
305 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
306 * lisp.h (xputenv): New decl.
308 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

319 informative (Bug#12992).
321 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
323 Simplify get_lim_data.
324 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
325 Remove USG and vlimit methods; no longer used these days.
326 Add #error catchall just in case.
328 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
329 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
330 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
331 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
332 (deleted_pid_list, Fdelete_process, create_process)
333 (record_child_status_change, handle_child_signal, deliver_child_signal)
334 (init_process_emacs, syms_of_process):
335 Assume SIGCHLD is defined.
336 (parse_signal): Remove. All uses removed.
337 (abbr_to_signal): New static function.
338 (Fsignal_process): Use it to convert signal names to ints.
339 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
340 kill (getpgrp (), ...).
341 (emacs_sigaction_init): Assume SIGCHLD is defined.
342 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,

344 * syssignal.h (EMACS_KILLPG): Remove.
345 All uses replaced by 'kill' with a negative pid.
346 (SIGCHLD): Remove definition, as we now assume SIGCHLD.

349 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
351 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
352 This will cause a production Emacs to dump core instead of
355 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
357 * frame.c (make_frame): Do not set window's buffer to t.
358 * window.c (Fsplit_window_internal): Likewise. Previously it was
359 used to indicate that the window is being set up. Now we use
360 set_window_buffer for all new windows, so the condition in ...
361 (Fset_window_buffer): ... is always true and can be removed.
363 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
365 Convenient macro to check whether the buffer is hidden.
366 * buffer.h (BUFFER_HIDDEN_P): New macro.
367 * frame.c (make_frame): Use it. Adjust comment.

371 2012-12-06 Eli Zaretskii <eliz@gnu.org>
373 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
374 if the child process is still running. Instead, exit the wait
375 loop and return zero. (Bug#13086)
377 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
379 * frame.h (x_char_width, x_char_height): Remove prototypes.

388 (command_loop_2, top_level_1): Add static to match prototype.
390 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
392 Fix a recently-introduced delete-process race condition.
393 * callproc.c, process.h (record_kill_process):
394 New function, containing part of the old call_process_kill.
395 (call_process_kill): Use it.
396 This does not change call_process_kill's behavior.
397 * process.c (Fdelete_process): Use record_kill_process to fix a
398 race condition that could cause Emacs to lose track of a child.
400 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
402 Avoid code duplication between prev_frame and next_frame.
403 * frame.c (candidate_frame): New function. Add comment.
404 (prev_frame, next_frame): Use it. Adjust comment.
406 2012-12-06 Eli Zaretskii <eliz@gnu.org>
408 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
409 fails, signal an error instead of continuing with an empty
411 Encode expanded temp file pattern before passing it to mkstemp or
414 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
415 Encode the file name before passing it to dostounix_filename, in
416 case it will downcase it (under w32-downcase-file-names).
419 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
421 Minor call-process cleanups.
422 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
423 at the same time as other platforms, to simplify analysis.
424 No need for fd0_volatile since we have synch_process_fd.
425 Avoid needless emacs_close; arg is always negative.
427 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
429 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
432 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
434 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
435 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
436 and mouse_face_hidden members to a bitfields.
437 * frame.h (struct frame): Remove set-but-not-used space_width member.
438 (FRAME_SPACE_WIDTH): Remove.
439 * nsterm.m, w32term.c, xterm.c: Adjust users.
440 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
441 member. Adjust users. Convert term_initted, delete_in_insert_mode,
442 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
443 members to a bitfields.
445 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
447 Don't let call-process be a zombie factory (Bug#12980).
448 Fixing this bug required some cleanup of the signal-handling code.
449 As a side effect, this change also fixes a longstanding rare race
450 condition whereby Emacs could mistakenly kill unrelated processes,
451 and it fixes a bug where a second C-g does not kill a recalcitrant
452 synchronous process in GNU/Linux and similar platforms.
453 The patch should also fix the last vestiges of Bug#9488,
454 a bug which has mostly been fixed on the trunk by other changes.
455 * callproc.c, process.h (synch_process_alive, synch_process_death)
456 (synch_process_termsig, sync_process_retcode):
457 Remove. All uses removed, to simplify analysis and so that
458 less consing is done inside critical sections.
459 * callproc.c (call_process_exited): Remove. All uses replaced
460 with !synch_process_pid.
461 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
462 These take the role of what used to be in unwind-protect arg.
464 (block_child_signal, unblock_child_signal):
465 New functions, to avoid races that could kill innocent-victim processes.
466 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
467 (call_process_kill): Record killed processes as deleted, so that
468 zombies do not clutter up the system. Do this inside a critical
469 section, to avoid a race that would allow the clutter.
470 (call_process_cleanup): Fix code so that the second C-g works again
471 on common platforms such as GNU/Linux.
472 (Fcall_process): Create the child process in a critical section,
473 to fix a race condition. If creating an asynchronous process,
474 record it as deleted so that zombies do not clutter up the system.
475 Do unwind-protect for WINDOWSNT too, as that's simpler in the
476 light of these changes. Omit unnecessary call to emacs_close
477 before failure, as the unwind-protect code does that.
478 * callproc.c (call_process_cleanup):
479 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
480 * process.c (record_deleted_pid): New function, containing
481 code refactored out of Fdelete_process.
482 (Fdelete_process): Use it.
483 (process_status_retrieved): Remove. All callers changed to use
485 (record_child_status_change): Remove, folding its contents into ...
486 (handle_child_signal): ... this signal handler. Now, this
487 function is purely a handler for SIGCHLD, and is not called after
488 a synchronous waitpid returns; the synchronous code is moved to
489 wait_for_termination. There is no need to worry about reaping
490 more than one child now.
491 * sysdep.c (get_child_status, child_status_changed): New functions.
492 (wait_for_termination): Now takes int * status and bool
493 interruptible arguments, too. Do not record child status change;
494 that's now the caller's responsibility. All callers changed.
495 Reimplement in terms of get_child_status.
496 (wait_for_termination_1, interruptible_wait_for_termination):

569 * callproc.c (Fcall_process):
570 * process.c (create_process):
571 Don't save and restore environ; no longer needed.

606 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
608 * callproc.c (Fcall_process): Fix vfork portability problems.
609 Do not assume that fd[0], count, filefd, and save_environ survive
610 vfork. Fix bug whereby wrong errno value could be reported for
611 pipe failure. Some minor cleanups, too, as follows. Move buf and
612 bufsize to the context where they're needed. Change new_argv to
613 be of type char **, as this is more convenient and avoids casts.
614 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
615 Now local constants, not macros.
617 2012-11-18 Kenichi Handa <handa@gnu.org>

667 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
668 between bpos_covered and bpos_max. This fixes cursor display when
669 several display strings follow each other.
671 * .gdbinit (pgx): If the glyph's object is a string, display the
672 pointer to string data, rather than the value of the string object
673 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
675 * indent.c (Fvertical_motion): If the starting position is covered
676 by a display string, return to one position before that, to avoid
677 overshooting it inside move_it_to. (Bug#12930)
679 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

704 * dired.c: Assume HAVE_DIRENT_H.
705 (NAMLEN): Remove, replacing with ...
706 (dirent_namelen): New function. All uses changed. Use the GNU macro
707 _D_EXACT_NAMELEN if available, as it's faster than strlen.
708 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
709 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
710 * makefile.w32-in (DIR_H): Remove. All uses replaced with

720 * xftfont.c (xftfont_open): Remove duplicate assignment.
722 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>

725 gc_in_progress to avoid note_mouse_highlight glitch with GC.
726 * frame.h (FRAME_MOUSE_UPDATE): New macro.
727 * msdos.c (IT_frame_up_to_date): Use it here...
728 * w32term.c (w32_frame_up_to_date): ...here...
729 * xterm.c (XTframe_up_to_date): ...and here...
730 * nsterm.m (ns_frame_up_to_date): ...but not here.
731 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
733 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

740 simplify large 'if' statements.
741 (redisplay_internal): Generalize commonly used
742 'tail' and 'frame' local variables.
744 2012-11-22 Eli Zaretskii <eliz@gnu.org>

747 with Windows system header.
749 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
751 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

776 Define for the MSVC compiler.
778 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
780 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
781 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
782 dostounix_filename. Prevents crashes down the road, because
783 dostounix_filename assumes it gets a unibyte string. Reported by
784 Michel de Ruiter <michel@sentient.nl>, see
785 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
787 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

816 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
817 (syms_of_eval): Remove corresponding defsubr.

827 Rename cygwin_convert_path* to cygwin_convert_file_name*.
829 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
831 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
833 2012-11-18 Eli Zaretskii <eliz@gnu.org>
835 * w32select.c: Include w32common.h before w32term.h, so that
836 windows.h gets included before w32term.h uses some of its
839 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
841 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

869 * emacs.c, term.c (O_RDWR): Remove.
870 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than

872 * nsterm.m: Assume <fcntl.h> exists.
873 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
874 (create_pty, Fmake_network_process, server_accept_connection)
875 (wait_reading_process_output, init_process_emacs):
877 (wait_reading_process_output): Put in a special case for WINDOWSNT
878 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
879 It's not clear this is needed, but it's a more-conservative change.
880 (create_process): Assume FD_CLOEXEC.
881 (create_process, create_pty): Assume O_NOCTTY.
882 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
883 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.

886 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
888 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
889 lack it, since gnulib guarantees this.
890 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
892 2012-11-17 Eli Zaretskii <eliz@gnu.org>
894 * w32.c (faccessat): Pretend that directories have the execute bit
895 set. Emacs expects that, e.g., in files.el:cd-absolute.
897 * w32proc.c (create_child): Don't clip the PID of the child
898 process to fit into an Emacs integer, as this is no longer a
900 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
901 reaping only the process specified by PID argument, if that is
902 positive. Use PID instead of dead_child to know which process to
903 reap. Wait for the child to die only if WNOHANG is not in
905 (sys_select): Don't set dead_child.
907 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
908 as it is no longer needed.
910 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,

913 record_at_most_one_child for the !WNOHANG case.

917 Fix problems in ns port found by static checking.
918 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
919 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
920 not to process group.
921 (ns_select): Use emacs_write, not write, as that's more robust
922 in the presence of signals.
923 (fd_handler:): Check for read errors.
925 2012-11-16 Glenn Morris <rgm@gnu.org>
927 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

933 2012-11-16 Eli Zaretskii <eliz@gnu.org>
935 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
936 use the same value of thread handle.
937 (start_timer_thread): If the timer thread exited (due to error),
938 clean up by closing the two handles it used. Duplicate the caller
939 thread's handle here, so it gets duplicated only once, when
940 launching the timer thread. Set priority of the timer thread, not
942 (getitimer): Don't duplicate the caller thread's handle here.
945 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
947 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
950 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
952 Remove no-longer-used pty_max_bytes variable.
953 * process.c (pty_max_bytes): Remove; unused.
954 (send_process): Do not set it.
956 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
958 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
961 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
963 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
964 This follows up on the 2012-09-29 patch that removed indirection
965 for the 'function' field. Reported by Sergey Vinokurov in
966 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
968 2012-11-14 Eli Zaretskii <eliz@gnu.org>
970 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
971 different name, as the MS runtime does not have such a function,
972 and probably never will.) All callers changed. Ignore DIRFD
973 value if PATH is an absolute file name, to match Posix spec
974 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
977 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
979 * xdisp.c (echo_area_display, redisplay_internal):
980 Omit redundant check whether frame_garbaged is set.

984 Use faccessat, not access, when checking file permissions (Bug#12632).
985 This fixes a bug that has been present in Emacs since its creation.
986 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
987 which must set some sort of record. (Torek's bug report was against
988 a predecessor of GNU Emacs, but GNU Emacs happened to have the
989 same common flaw.) See Torek's Usenet posting
990 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
991 Posted: Fri Apr 8 14:18:56 1983.
992 * Makefile.in (LIB_EACCESS): New macro.
994 * callproc.c (init_callproc):
995 * charset.c (init_charset):
996 * fileio.c (check_existing, check_executable, check_writable)
998 * lread.c (openp, load_path_check):
999 * process.c (allocate_pty):
1001 Use effective UID when checking permissions, not real UID.
1002 * callproc.c (init_callproc):
1003 * charset.c (init_charset):
1004 * lread.c (load_path_check, init_lread):
1005 Test whether directories are accessible, not merely whether they exist.
1006 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1007 * fileio.c (check_existing, check_executable, check_writable)
1009 Use symbolic names instead of integers for the flags, as they're
1011 (check_writable): New arg AMODE. All uses changed.
1012 Set errno on failure.
1013 (Ffile_readable_p): Use faccessat, not stat + open + close.
1014 (Ffile_writable_p): No need to call check_existing + check_writable.
1015 Just call check_writable and then look at errno. This saves a syscall.
1016 dir should never be nil; replace an unnecessary runtime check
1017 with an eassert. When checking the parent directory of a nonexistent
1018 file, check that the directory is searchable as well as writable, as
1019 we can't create files in unsearchable directories.
1020 (file_directory_p): New function, which uses 'stat' on most platforms
1021 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1022 (Ffile_directory_p, Fset_file_times): Use it.
1023 (file_accessible_directory_p): New function, which uses a single
1024 syscall for efficiency.
1025 (Ffile_accessible_directory_p): Use it.
1026 * xrdb.c (file_p): Use file_directory_p.
1027 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1028 * lread.c (openp): When opening a file, use fstat rather than
1029 stat, as that avoids a permissions race. When not opening a file,
1030 use file_directory_p rather than stat.
1031 (dir_warning): First arg is now a usage string, not a format.
1032 Use errno. All uses changed.
1033 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1034 that merely introduced a race.
1035 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1036 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1037 and similarly for the other O_* flags.
1038 * w32.c (sys_faccessat): Rename from sys_access and switch to
1039 faccessat's API. All uses changed.
1040 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1041 (magic_db): Rename from magic_file_p.
1042 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1043 char *, so that we don't have to test for file existence
1044 separately from opening the file for reading. This removes a race
1045 fixes a permission-checking problem, and simplifies the code.
1047 (file_p): Remove; no longer needed.
1049 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1051 Omit glyphs initialization at startup.
1052 * dispnew.c (glyphs_initialized_initially_p): Remove.
1053 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1054 (Fredraw_frame): Move actual code from here...
1055 (redraw_frame): ...to here. Add eassert. Adjust comment.
1056 (Fredraw_display): Use redraw_frame.
1057 * xdisp.c (clear_garbaged_frames): Likewise.
1059 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1061 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1062 passed to pint2str and pint2hrstr to be at most the size of the
1063 frame's decode_mode_spec_buffer. This avoids crashes with very
1064 large values of FIELD_WIDTH argument to decode_mode_spec.
1067 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1069 Fix a race with verify-visited-file-modtime (Bug#12863).
1070 Since at least 1991 Emacs has ignored an mtime difference of no
1071 more than one second, but my guess is that this was to work around
1072 file system bugs that were fixed long ago. Since the race is
1073 causing problems now, let's remove that code.
1074 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1075 whose time stamp is off by no more than a second. Insist that the
1076 file time stamps match exactly.
1078 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1080 * frame.h (struct frame): Convert external_tool_bar member to
1081 1-bit unsigned bitfield.
1082 * termhooks.h (struct terminal): Remove mouse_moved member since
1083 all users are long dead. Adjust comment on mouse_position_hook.
1085 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1087 Simplify by using FOR_EACH_FRAME here and there.
1088 * frame.c (next_frame, prev_frame, other_visible_frames)
1089 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1090 * w32term.c (x_window_to_scroll_bar): Likewise.
1091 * window.c (window_list): Likewise.
1092 * xdisp.c (x_consider_frame_title): Likewise.
1093 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1094 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1095 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1096 * xmenu.c (menubar_id_to_frame): Likewise.
1097 * xselect.c (frame_for_x_selection): Likewise.
1098 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1099 (x_window_to_menu_bar): Likewise.
1100 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1102 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1104 * data.c (Qdefalias_fset_function): Now static.
1106 Another tweak to vectorlike_header change.
1107 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1108 Remove, and replace all uses with ...
1109 (next_in_free_list, set_next_in_free_list):
1110 New functions, which respect C's aliasing rules better.
1112 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1114 * window.c (list4i): Rename from 'quad'. All uses changed.
1115 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1117 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1119 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1120 warning about mixing declarations and code in ISO C90.
1122 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1124 * window.c (Fsplit_window_internal): Set combination limit of
1125 new parent window to t iff Vwindow_combination_limit is t;
1126 fixing a regression introduced with the change from 2012-09-22.
1127 (Fset_window_combination_limit): Fix doc-string.
1129 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1131 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1132 amount when the scroll margins are too large. When scrolling
1133 backwards in the buffer, give up if cannot reach point or the
1134 scroll margin within a reasonable number of screen lines.
1135 Fixes point position in window under scroll-up/down-aggressively when
1136 point is positioned many lines beyond the window top/bottom.
1139 * ralloc.c (relinquish): If real_morecore fails to return memory
1140 to the system, don't crash; instead, leave the last heap
1141 unchanged and return. (Bug#12774)
1143 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1145 * lisp.h (AUTOLOADP): New macro.

1150 (Finteractive_form): Simplify.
1151 (Fquo): Don't insist on having at least 2 arguments.
1152 (Qdefalias_fset_function): New var.
1154 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1156 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1160 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1162 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1164 Fix recently introduced crash on MS-Windows (Bug#12839).
1165 * w32term.h (struct scroll_bar): Use convenient header.
1166 (SCROLL_BAR_VEC_SIZE): Remove.
1167 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1169 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1171 Tweak last vectorlike_header change.
1172 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1173 vectorlike object on the free list. This is introduced to avoid
1174 some (but not all) pointer casting and aliasing problems, see
1175 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1176 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1180 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1182 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1183 been removed, so remove them here also.
1185 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1187 * doc.c (Fdocumentation): Handle new property
1188 dynamic-docstring-function to replace the old ad-advice-info.
1190 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1192 * fns.c (Qeql, hashtest_eq): Now static.
1194 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1196 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1197 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1198 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

1204 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1205 * lisp.h (sxhash_combine): New inline function, with the contents
1206 of the old SXHASH_COMBINE.

1212 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1213 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1214 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1217 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1219 * image.c (xpm_make_color_table_h): Fix compiler error because
1220 make_hash_table changed.

1224 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1226 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1228 Use ad-hoc comparison function for the profiler's hash-tables.
1229 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1230 (make_log): Use them.
1231 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1232 call Fequal any more.

1280 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1281 (Fmake_bool_vector): Likewise.
1282 (struct large_vector): New type to represent allocation unit for
1283 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1284 (large_vectors): Change type to struct large_vector.
1285 (allocate_vector_from_block): Simplify.
1286 (PSEUDOVECTOR_NBYTES): Replace with...
1287 (vector_nbytes): ...new function. Adjust users.

1308 * keyboard.c (event_to_kboard): Do not dereference
1309 frame_or_window field of SELECTION_REQUEST_EVENT
1310 and SELECTION_CLEAR_EVENT events (Bug#12814).
1311 * xterm.h (struct selection_input_event): Adjust comment.
1313 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1315 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1316 such as Scroll Lock, if the respective keys are treated as
1317 function keys, not as modifiers. This avoids destroying non-ASCII
1318 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1320 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1322 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1324 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1326 Restore some duplicate definitions (Bug#12814).
1327 This undoes part of the 2012-11-03 changes. Some people build
1328 with plain -g rather than with -g3, and they need the duplicate
1329 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1330 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1331 Define as macros, as well as as enums or as constants.

1336 to keypad keys (Bug#12816).
1338 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1340 Minor adjustments of recently-changed frame functions.
1341 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1342 known to be a frame (we're in the FRAMEP branch).
1343 * lisp.h (Qframep): Remove decl. frame.h declares this.
1344 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1345 since they're meant for Lisp fixnum values.
1347 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1349 * window.c (Fwindow_combination_limit): Revert to the only
1350 required argument and adjust docstring as suggested in
1351 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1352 by Martin Rudalics <rudalics@gmx.at>.

1403 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1405 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.

1409 2012-11-05 Chong Yidong <cyd@gnu.org>
1411 * process.c (wait_reading_process_output): Revert previous change.

1415 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1416 This removes code that has been obsolete since around 1990.
1417 * callproc.c (Fcall_process):
1419 * process.c (create_process):
1420 * term.c (dissociate_if_controlling_tty):
1421 Assume setsid exists.
1422 * callproc.c (child_setup): Assume setpgid exists and behaves as
1423 per POSIX.1-1988 or later.
1424 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1425 * emacs.c (shut_down_emacs):
1426 * sysdep.c (sys_suspend, init_foreground_group):
1427 Assume getpgrp behaves as per POSIX.1-1998 or later.
1428 * msdos.c (setpgrp): Remove.
1429 (tcgetpgrp, setpgid, setsid): New functions.
1430 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1431 * term.c (no_controlling_tty): Remove; unused.
1432 * w32proc.c (setpgrp): Remove.
1433 (setsid, tcgetpgrp): New functions.
1435 Simplify by assuming __fpending.
1436 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1437 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1438 Do not assume that __fpending's result fits in int.
1440 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1442 Remove EMACS_OUTQSIZE+sleep hack.
1443 * dispnew.c (update_frame_1): Remove hack for terminals slower
1444 than 2400 bps, which throttled Emacs by having it sleep.
1445 This code hasn't worked since at least 2007, when the multi-tty stuff
1446 was added, and anyway those old terminals are long dead.
1447 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1448 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1450 Fix data-loss with --version (Bug#9574).
1451 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1452 as we can't assume that emacs_strerror is initialized, and strerror
1453 is good enough here.
1454 (main): Invoke atexit earlier, to catch earlier instances of
1455 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1457 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1459 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1460 (keyDown): Remap keypad keys to X11 virtual key codes.
1462 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1464 Fix data-loss with --batch (Bug#9574).
1465 * emacs.c: Include <close-stream.h>.
1466 (close_output_streams): New function.
1467 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1468 and handles errors appropriately.
1469 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1472 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1473 The symptom is a diagnostic "GLib-WARNING **: In call to
1474 g_spawn_sync(), exit status of a child process was requested but
1475 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1476 waitpid(), so exit status can't be returned." The diagnostic
1477 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1478 The real bug is a race condition between Emacs and glib: Emacs
1479 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1480 so that glib can't find it. Work around the bug by invoking
1481 waitpid only on subprocesses that Emacs itself creates.
1482 * process.c (create_process, record_child_status_change):
1483 Don't use special value -1 in pid field, as the caller now must
1484 know the pid rather than having the callee infer it.
1485 The inference was sometimes incorrect anyway, due to another race.
1486 (create_process): Set new 'alive' member if child is created.
1487 (process_status_retrieved): New function.
1488 (record_child_status_change): Use it.
1489 Accept negative 1st argument, which means to wait for the
1490 processes that Emacs already knows about. Move special-case code
1491 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1492 processes that have already been waited for, by testing and
1493 clearing new 'alive' member.
1494 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1495 now does this internally.
1496 (handle_child_signal): Let record_child_status_change do all
1497 the work, since we do not want to reap all exited child processes,
1498 only the child processes that Emacs itself created.
1499 * process.h (Lisp_Process): New boolean member 'alive'.
1501 Omit duplicate definitions no longer needed with gcc -g3.
1502 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1503 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1504 Define only as macros. There's no longer any need to also define
1505 these symbols as enums or as constants, since we now assume
1506 gcc -g3 when debugging.
1508 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1510 * lisp.mk: Adjust comments to the fact that term/internal is now
1511 loaded from loadup.el.
1513 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1514 (msdos_fatal_signal): New function.
1515 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1518 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1519 for GCC versions before 4.
1520 (emacs_raise): Define to call msdos_fatal_signal.
1522 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1523 iterator when starting in the middle of a display or overlay
1526 2012-11-03 Chong Yidong <cyd@gnu.org>
1528 * process.c (wait_reading_process_output): Clean up the last
1531 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1533 * process.c (wait_reading_process_output): Avoid a race condition
1534 with SIGIO delivery (Bug#11536).
1536 2012-11-03 Chong Yidong <cyd@gnu.org>
1538 * buffer.c (cursor_type): Untabify docstring.
1540 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1542 * frame.h (struct frame): Drop can_have_scroll_bars member
1543 which is meaningless for a long time. Adjust comments.
1544 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1545 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1547 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1549 * window.c (decode_next_window_args): Update window arg after
1550 calling decode_live_window and so fix crash reported at
1551 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1552 by Juanma Barranquero <lekktu@gmail.com>.
1553 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1554 * font.c (Ffont_at): Likewise.
1556 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1558 * widget.c (resize_cb): New function.
1559 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1560 (EmacsFrameResize): Check if all is up to date before changing frame
1563 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1565 Implement backtrace output for fatal errors on MS-Windows.
1566 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1567 (BACKTRACE_LIMIT_MAX): New macro.
1568 (w32_backtrace): New function.
1569 (emacs_abort): Use w32_backtrace when the user chooses not to
1570 attach a debugger. Update the text of the abort dialog.
1572 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1574 Window-related stuff cleanup here and there.
1575 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1576 Use decode_any_window.
1577 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1578 * xdisp.c (Fformat_mode_line): Likewise.
1579 * font.c (Ffont_at): Use decode_live_window.
1580 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1581 * window.c (decode_next_window_args): Likewise.
1582 (decode_any_window): Remove static.
1583 * window.h (decode_any_window): Add prototype.
1584 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1585 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1588 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1590 Remove pad from struct input_event.
1591 * termhooks.h (struct input_event): Remove padding field.
1593 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1594 member is never cons for a long time. Adjust comment.
1595 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1596 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1597 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1598 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1600 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1602 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1604 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1606 Fix crash when using Emacs as commit editor for git (Bug#12697).
1607 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1608 and it is configured in conf_post.h.
1609 (Fcall_process): Don't invoke both setsid and setpgid; the former
1610 is enough, if it exists.
1611 * callproc.c (Fcall_process, child_setup):
1612 * process.c (create_process): Use setpgid.
1613 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1615 * dispnew.c (init_display): Initialize the foreground group
1616 if we are running a tty display.
1617 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1618 * lisp.h (init_foreground_group): New decl.
1619 * sysdep.c (inherited_pgroup): New static var.
1620 (init_foreground_group, tcsetpgrp_without_stopping)
1621 (narrow_foreground_group, widen_foreground_group): New functions.
1622 (init_sys_modes): Narrow foreground group.
1623 (reset_sys_modes): Widen foreground group.
1625 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1627 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1629 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1631 * minibuf.c (read_minibuf): Restore current buffer since
1632 choose_minibuf_frame calling Fset_frame_selected_window may
1633 change it (Bug#12766).
1635 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1637 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1639 2012-10-30 Kenichi Handa <handa@gnu.org>
1641 * font.c (Ffont_at): If WINDOW is specified and it is not
1642 displaying the current buffer, signal an error.
1644 2012-10-29 Daniel Colascione <dancol@dancol.org>
1646 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1647 In preparation for fixing bug#12739, move these functions from
1650 * coding.h, coding.c: ... to here, and compile them only when
1651 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1652 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1654 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1656 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1657 (timer_loop, getitimer, setitimer): Use it instead of
1658 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1660 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1663 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1665 * nsterm.m (NO_APPDEFINED_DATA): New define.
1666 (last_appdefined_event_data): New variable
1667 (last_appdefined_event): Remove.
1668 (ns_select): Initialize t from last_appdefined_event_data instead
1669 of [last_appdefined_event data1].
1670 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1671 remove last_appdefined_event (Bug#12698).
1673 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1675 * frame.c (x_set_font): Catch internal error.
1677 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1679 Avoid overflow in w32 implementation of interval timers.
1680 When possible, for ITIMER_PROF count only times the main thread
1682 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1683 'volatile ULONGLONG' types. All the other data which was
1684 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1685 (GetThreadTimes_Proc): New typedef.
1686 (w32_get_timer_time): New function, returns a suitable time value
1688 (timer_loop): Enter critical section when accessing ULONGLONG
1689 values of the itimer_data struct, as these accesses are no longer
1690 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1691 Remove unused variable.
1692 (init_timers): Initialize s_pfn_Get_Thread_Times.
1693 (start_timer_thread): Don't assign itimer->caller_thread here.
1694 (getitimer): Assign itimer->caller_thread here.
1695 (setitimer): Always call getitimer to get the value of ticks_now.
1696 (sys_spawnve): Avoid compiler warning about format mismatch.
1698 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1700 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1701 mouse movement events if the menu bar is active. This avoids
1702 producing a busy "hour-glass" cursor by Windows if the mouse
1703 pointer is positioned over a tooltip shown for some menu item.
1705 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1707 Don't assume process IDs fit in int.
1708 * emacs.c (shut_down_emacs) [!DOS_NT]:
1709 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1710 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1711 Use pid_t, not int, to store process IDs, as 'int'
1712 is not wide enough on a few platforms (e.g., AIX and IRIX).
1714 2012-10-23 Kenichi Handa <handa@gnu.org>
1716 The following change is to make face-font-rescale-alist work
1717 correctly for non-ASCII fonts.
1719 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1720 (font_open_for_lface): Handle Vface_font_rescale_alist.
1722 2012-10-23 Chong Yidong <cyd@gnu.org>
1724 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1726 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1728 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1730 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1732 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1735 2012-10-21 Glenn Morris <rgm@gnu.org>
1737 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1739 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1741 Port to OpenBSD 5.1.
1742 * frame.c (Fmouse_position, Fmouse_pixel_position):
1743 * xdisp.c (produce_stretch_glyph):
1744 Declare local vars only when they're needed.
1745 This is clearer and avoids a warning on OpenBSD about unused vars.
1746 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1747 This is safer, and avoids OpenBSD warnings about unused vars.
1748 * keyboard.c (record_menu_key): Remove unnecessary decl.
1749 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1750 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1751 as our definition clashes with OpenBSD's.
1752 * xfaces.c (load_face_colors, check_lface_attrs)
1753 (get_lface_attributes_no_remap, get_lface_attributes)
1754 (lface_fully_specified_p, x_supports_face_attributes_p)
1755 (tty_supports_face_attributes_p, face_fontset, realize_face)
1756 (realize_x_face, realize_tty_face):
1757 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1758 merely Lisp_Object *. This is more informative and avoids
1759 a warning on OpenBSD about accessing beyond an object's size.
1761 2012-10-20 Chong Yidong <cyd@gnu.org>
1763 * lread.c (Fload): Doc fix (Bug#12592).
1765 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1767 * font.c (Ffont_at): Fix previous change.
1769 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1771 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1772 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1775 * alloc.c (NSTATICS): Decrease to 0x800.
1777 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
1779 * fns.c (Fnreverse): Include the problem element when signaling an
1782 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1784 * nsterm.m (ns_select): Check writefds before call to
1785 FD_ISSET (Bug#12668).
1787 2012-10-18 Daniel Colascione <dancol@dancol.org>
1789 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1790 (staticpro): If we run out of staticpro slots, die with an
1791 informative error instead of just calling emacs_abort.
1793 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1795 Fix two flaws reported by Dmitry Antipov.
1796 * window.c (Ftemp_output_buffer_show): Remove.
1797 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
1798 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
1800 2012-10-17 Eli Zaretskii <eliz@gnu.org>
1802 * makefile.w32-in ($(BLD)/w32.$(O)):
1803 ($(BLD)/vm-limit.$(O)):
1805 ($(BLD)/unexw32.$(O)):
1806 ($(BLD)/fileio.$(O)):
1807 ($(BLD)/dispnew.$(O)): Update dependencies.
1809 * w32term.h (w32_initialize_display_info, initialize_w32_display):
1812 * w32proc.c: Include ctype.h.
1814 * w32.h (init_environment, check_windows_init_file)
1815 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
1816 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
1817 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1818 (sys_link): Add prototypes.
1820 * w32.c: Include w32select.h.
1821 (sys_access, e_malloc, sys_select): Add prototypes.
1822 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
1824 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
1826 * unexw32.c: Include lisp.h and w32.h.
1828 * term.c [WINDOWSNT]: Include w32term.h.
1830 * process.c [WINDOWSNT]: Add prototype of sys_select.
1832 * fileio.c [WINDOWSNT]: Include w32.h.
1834 * dispnew.c [WINDOWSNT]: Include w32.h.
1836 * cygw32.c (Fcygwin_convert_path_to_windows)
1837 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
1838 Lisp_Object values. (Bug#12661)
1840 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
1841 to Lisp_Object. (Bug#12661)
1843 2012-10-17 Kenichi Handa <handa@gnu.org>
1845 * xdisp.c (reseat_1): Make the information stored in it->cmp_it

1851 reset its buffer pointer to NULL (Bug#12652).
1853 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
1855 Do not verify indirection counters of killed buffers (Bug#12579).
1856 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
1857 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
1859 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
1861 * alloc.c (Fmake_byte_code): Fix typo in comment.
1862 * print.c (print_interval): Define as static to match prototype.
1863 * indent.c (disptab_matches_widthtab, recompute_width_table):
1866 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
1868 * editfns.c (get_system_name): Remove.
1869 * lisp.h (get_system_name): Remove prototype.
1870 * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes.
1871 (get_environ_db): Use Vsystem_name. Avoid call to strlen.
1873 2012-10-15 Daniel Colascione <dancol@dancol.org>
1875 * dbusbind.c: Add comment explaining reason for previous change.
1877 2012-10-15 Martin Rudalics <rudalics@gmx.at>
1879 * window.c (Fwindow_end): Rewrite check whether cached position
1880 can be used (Bug#12600).
1881 (resize_frame_windows, grow_mini_window, shrink_mini_window):
1882 Set windows_or_buffers_changed.

1892 * image.c (init_tiff_functions, init_imagemagick_functions)
1893 (init_svg_functions): Fix cygw32 build break by using these
1894 functions only when WINDOWSNT _and_ HAVE_NTGUI.

1915 Fix some stat-related races.
1916 * fileio.c (Fwrite_region): Avoid race condition if a file is
1917 removed or renamed by some other process immediately after Emacs
1918 writes it but before Emacs stats it. Do not assume that stat (or
1920 * image.c (slurp_file): Resolve the file name with fopen + fstat
1921 rather than stat + fopen.

1947 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
1949 * fileio.c (check_existing): New function.
1950 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1951 instead of calling 'stat', when what's needed is to check whether
1952 a file exists. This avoids expensive system calls on MS-Windows.
1955 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1957 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

1962 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
1964 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

2004 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
2006 * marker.c (cached_modiff): EMACS_INT, not int.
2008 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
2009 instead of having a wrong decl.

2048 * process.c (wait_reading_process_output):
2049 Use unsigned for counter where wraparound-on-overflow is desired,
2050 since unsigned is guaranteed to have that behavior and signed is not.
2051 (read_char): Use ptrdiff_t for string length.
2052 (get_input_pending): Remove first argument, since it was always
2053 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2054 and behave as if it had that value. Return new value of
2055 input_pending. All callers changed.
2056 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2057 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2059 * keymap.c (push_key_description): Omit last arg, which was always 1.
2060 All callers changed.
2062 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
2064 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

2080 Don't include termopts.h.
2082 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2084 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2086 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2088 * commands.h (immediate_quit): Remove duplicate decl.
2090 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2092 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
2094 (nsfont_open): Remove setting of Vfonts_in_cache.
2095 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2097 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2099 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2100 match what GetLastError returns. Explain why the function is
2103 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2104 'is_tooltip_frame', to avoid confusion with its global namesake.
2106 2012-10-08 Daniel Colascione <dancol@dancol.org>
2108 * xdisp.c (start_hourglass): Call w32_note_current_window when
2109 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2110 build that caused Emacs to display the hourglass cursor forever.
2112 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2113 which is broken under remote desktop, calculate the number of
2114 colors available for a display based on the display's number of
2115 planes and number of bits per pixel per plane. (bug#10397).
2117 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2119 * nsfont.m (Vfonts_in_cache): New variable.
2120 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2121 are used. Add cached fonts to Vfonts_in_cache.
2122 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2124 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2126 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2128 (FONT_H): Define after FRAME_H.
2129 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2130 Update dependencies.
2132 * w32term.c: Remove leftover declaration of keyboard_codepage.
2134 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2136 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2137 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2138 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2139 (GLOBAL_SOURCES): Add cygw32.c.
2140 ($(BLD)/unexw32.$(O)):
2142 ($(BLD)/w32console.$(O)):
2143 ($(BLD)/w32fns.$(O)):
2144 ($(BLD)/w32heap.$(O)):
2145 ($(BLD)/w32menu.$(O)):
2146 ($(BLD)/w32proc.$(O)): Add w32common.h.
2148 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2150 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2152 2012-10-08 Daniel Colascione <dancol@dancol.org>
2154 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2155 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2156 accidental message numbering hole. Change other messages to
2159 * w32select.h (HAVE_W32SELECT): Remove.
2161 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2162 w32common.h instead of w32heap.h.
2164 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2165 (get_allocation_unit, get_processor_type, get_w32_major_version)
2166 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2167 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2168 (OS_NT, os_subtype, cache_system_info): Move declarations to
2171 * w32heap.c: Include w32common.h.
2172 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2173 (w32_minor_version, w32_build_number, w32_subtype):
2174 Remove duplicate definitions.
2176 * w32fns.c: Include w32common.h; include w32heap.h only in
2179 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2180 Use `report_file_error' instead of `error' in order to better
2181 inform users of what went wrong. Increase NTGUI_UNICODE file
2182 dialog box file name length to 32k, the maximum allowed by the NT
2185 * w32common.h: New file.
2186 (ROUND_UP, ROUND_DOWN, get_page_size)
2187 (get_allocation_unit, get_processor_type, get_w32_major_version)
2188 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2189 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2190 (OS_NT, os_subtype, cache_system_info): Move here.
2192 * unexw32.c, unexcw.c: Include w32common.h.
2194 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2195 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2196 to call syms_of_w32select.
2198 * cygw32.h: Remove obsolete EXFUN declarations.
2200 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2202 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2203 of w32inevt.o from SOME_MACHINE_OBJECTS.
2205 2012-10-08 Daniel Colascione <dancol@dancol.org>
2207 * image.c: Permanent fix for JPEG compilation issue --- limit
2208 jpeglib `boolean' redefinition to Cygwin builds.
2210 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2212 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2214 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2217 2012-10-08 Daniel Colascione <dancol@dancol.org>
2219 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2220 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2221 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2222 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2223 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2224 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2225 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2226 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2227 now a supported configuration.
2229 * Makefile.in: consolidate image variables into LIBIMAGE; add
2230 W32_OBJ and W32_LIBS. Compile new files.
2233 (_DebPrint) declare tracing facility for W32 debugging. We need
2234 to unify tracing later.
2236 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2237 unconditional use of W32 Unicode functions. Cygwin runs only on
2238 100% Unicode operating systems.
2240 * cygw32.c: New file. Define Cygwin-specific facilities.
2241 (Fcygwin_convert_path_to_windows)
2242 (Fcygwin_convert_path_from_windows): New user functions for
2243 accessing Cygwin path-munging routines.
2245 * cygw32.h: New file.
2246 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2247 UTF-16LE strings temporarily inside non-Lisp-visible string
2250 (w32_strerror): Just what it says on the tin.
2252 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2253 also run for Cygwin; both systems have the same problem with using
2254 GUI facilities in a forked child. Also call syms_of_cygw32,
2255 syms_of_w32select in correct places.
2257 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2258 needs fork-then-exec for daemon launching.
2260 * font.h: Include frame.h.
2262 * image.c: Use the image library cache machinery only when we're
2263 compiling for native WINDOWSNT; Cygwin can use shared libraries
2264 like any other Unixlike system.
2266 * keyboard.c: Clarify a comment regarding the input loop.
2268 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2269 functions directly instead of trying to detect at runtime that our
2270 host operating system supports them. We make this change for two
2271 reasons: Cygwin lacks support for the multibyte character
2272 conversion functions used by the legacy menu code, and Cygwin
2273 never needs to rely on non-Unicode APIs.
2275 * unexw32.c (hinst): Declare extern.
2277 * w32.c: Change header order;
2278 (w32_strerror): Move to w32fns.c because we need it for
2279 non-WINDOWSNT builds.
2281 * w32.h: Add #error macro to make sure we don't include w32.h for
2282 Cygwin builds. Remove w32select declarations.
2284 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2285 w32fns.c. w32console.c is WINDOWSNT-only.
2287 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2288 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2290 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2291 (w32_major_version, w32_minor_version, w32_build_number)
2292 (os_subtype, sound_type): Define here
2293 (w32_defined_color): Make color parameter const for consistency
2294 with other _defined_color functions.
2295 (w32_createwindow): Unconditionally call w32_init_class instead of
2296 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2297 through the code is complex and unnecessary because class
2298 registration is practically free.
2299 (w32_name_of_message): New EMACSDEBUG-only function.
2300 (Fset_message_beep): Move here
2301 (Fx_open_connection): Require that the display name for Windows be
2302 "w32" for consistency, emacsclient disambiguation, and maybe, one
2303 day, multi-window-system support.
2304 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2305 Cygwin files for W32 GUI facilities, since these clearly don't
2306 expect Cygwin names.
2307 (_DebPrint): Define.
2308 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2309 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2310 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2311 (w32_last_error): Remove.
2313 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2315 * w32heap.c (syspage_mask): Declare here.
2316 (cache_system_info): Remove.
2318 * w32inevt.c (faked_key): Define globally, not statically.
2319 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2320 (w32_console_toggle_lock_key): Move to w32fns.c.
2322 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2324 * w32proc.c (_DebPrint): Move to w32fns.c.
2325 * w32select.c: Include string.h, stdio.h for Cygwin.
2326 * w32select.h: New File.
2328 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2330 (w32_message_fd): New variable. Under Cygwin, holds the file
2331 descriptor the system used to tell us about pending thread
2334 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2335 that prevented compilation under non-WINDOWSNT systems.
2337 (w32_initialize): Open /dev/windows and assign it to
2338 w32_message_fd. Provide w32 feature.
2340 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2341 (WM_EMACS_INPUT_READY): add.
2342 (prepend_msg, w32_message_fd): Declare globally.
2345 (keyboard_handle): Use only when WINDOWSNT.
2346 (notify_msg_ready): New function. Posts a message to the main
2347 thread's message queue under CYGWIN, which wakes up the main
2348 thread from select(2) by making the /dev/windows file descriptor
2349 ready. Under WINDOWSNT, it sets an event the same way the old
2352 (post, prepend_msg): Actually call notify_msg_ready instead of
2353 setting the input event directly.
2355 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2357 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2358 but it still has blocs in it, don't return it to the system,
2359 instead of aborting. (Bug#12402)
2361 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2363 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

2374 MAC_OS_X_VERSION_10_4.
2376 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2377 MAC_OS_X_VERSION_10_2.

2394 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2396 Improve sys_siglist detection.
2397 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2398 defined as a macro, as is done in Solaris.
2399 (sys_siglist_entries): New macro.
2400 (save_strsignal): Use it.
2401 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2402 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2404 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2406 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2407 fullscreen/Fullscreen.
2409 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2410 tobar_height is new.
2412 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2413 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2414 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

2423 (canBecomeMainWindow): New function.
2425 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2427 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2429 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2431 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2433 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2434 that time stamps of directories could also be changed.
2435 Don't request the too broad GENERIC_WRITE, only the more restrictive
2436 FILE_WRITE_ATTRIBUTES access rights.
2438 * fileio.c (Fset_file_times): Special-case ignoring errors for
2439 directories only on MSDOS, not on MS-Windows.
2441 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2443 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2445 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2447 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2448 see whether CreateFile failed.
2450 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2452 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2453 to avoid similar races.
2454 * keyboard.c (pending_signals): Now bool, not int.
2456 Port timers to OpenBSD, plus check for timer failures.
2457 OpenBSD problem reported by Han Boetes.
2458 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2460 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2461 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2462 like OpenBSD, which has timer_settime but does not declare it.
2463 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2464 whether to use itimerspec-related primitives. All uses of
2465 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2467 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2469 * profiler.c (handle_profiler_signal): Fix a malloc race
2470 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2472 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2474 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2476 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2478 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2479 consistent with the change in return value of 'safe_strsignal'.
2481 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2483 Prefer plain 'static' to 'static inline' (Bug#12541).
2484 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2485 (bidi_set_sor_type, bidi_push_embedding_level)
2486 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2487 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

2491 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2492 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2493 Now 'static', not 'static inline'.
2495 Count overruns when profiling; change units to ns.
2496 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2497 Give extra weight to samples after overruns, to attempt to count
2498 the time more accurately.
2499 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2500 the underlying primitives nominally do ns.
2501 (Fprofiler_cpu_start): Document the change. Mention that
2502 the sampling intervals are only approximate.
2504 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2506 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2508 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2509 case for the special 0 coding-system.
2511 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2512 (Fmake_overlay): Remove redundant tests.
2513 (fix_start_end_in_overlays): Remove redundant recentering.
2515 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2517 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2518 Update dependencies.
2520 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2522 Fix a malloc race condition involving strsignal.
2523 A signal can arrive in the middle of a malloc, and Emacs's signal
2524 handler can invoke strsignal, which can invoke malloc, which is
2525 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2526 Fix it by altering the signal handler so that it does not invoke
2528 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2529 * process.c (status_message): Use const pointer, in case strsignal
2530 is #defined to safe_strsignal.
2531 * sysdep.c (sys_siglist, init_signals): Always define and
2532 initialize a substitute sys_siglist if the system does not define
2533 one, even if HAVE_STRSIGNAL.
2534 (safe_strsignal): Rename from strsignal. Always define,
2535 using sys_siglist. Return a const pointer.
2536 * syssignal.h (safe_strsignal): New decl.
2537 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2539 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2541 * w32proc.c (timer_loop): Fix code that waits for timer
2542 expiration, to avoid high CPU usage.
2544 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2546 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2547 (sweep_weak_table): Remove redundant prototypes.
2549 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2551 * emacs.c: Move the inclusion of TERM_HEADER after including
2552 windows.h on WINDOWSNT. This avoids compilation problems with
2555 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2557 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2558 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2559 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2560 as the previous version used 'void *'.
2562 * ralloc.c (ROUNDUP): Fix last change.
2563 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2566 * w32proc.c <disable_itimers>: New static flag.
2567 (init_timers): Initialize it to zero, after creating the critical
2568 sections used by the timer threads.
2569 (term_timers): Set to 1 before deleting the critical sections.
2570 (getitimer, setitimer): If disable_itimers is non-zero, return an
2571 error indication without doing anything. Reported by Fabrice
2572 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2573 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2575 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2578 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2579 term_ntproc after all the other bookkeeping, to get timers working
2580 as long as possible.
2582 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2584 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2585 Suggested by Juri Linkov in
2586 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2588 Prefer plain 'static' to 'static inline' (Bug#12541).
2589 With static functions, modern compilers inline pretty well by
2590 themselves; advice from programmers often hurts as much as it helps.
2591 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2592 this change shrinks the text size of the Emacs executable by 1.1%
2593 without affecting CPU significantly in my benchmark.
2594 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2674 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2676 Revert the FOLLOW-SYMLINKS change for file-attributes.
2677 Doing it right would require several changes to Tramp, and there's
2678 not enough time to get that tested before the freeze today.
2679 * dired.c (directory_files_internal, Ffile_attributes):
2682 * frame.c (x_report_frame_params): Port better to wider ints.
2683 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2684 or that pointers can be printed in 15 decimal digits.
2685 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2721 * vm-limit.c (lim_data): Now size_t.
2722 (check_memory_limits): Adjust prototypes of real_morecore and
2723 __morecore to receive argument of type ptrdiff_t. Use size_t for

2797 Remove, no longer used.
2798 (w32_note_current_window, show_hourglass, hide_hourglass):
2799 New functions, in support of hourglass cursor display similar to other
2801 (syms_of_w32fns): Don't initialize hourglass_timer.
2803 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
2805 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
2807 * w32.h (init_timers, term_timers): Add prototypes.
2809 2012-09-30 Kenichi Handa <handa@gnu.org>

2850 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
2852 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
2854 2012-09-30 Chong Yidong <cyd@gnu.org>
2856 * fns.c (Frandom): Doc fix.
2858 2012-09-30 Martin Rudalics <rudalics@gmx.at>

2861 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
2863 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2865 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
2866 Suggested by Eli Zaretskii in
2867 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2869 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2871 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2872 HAVE_TIMER_SETTIME is defined.
2874 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2876 Profiler improvements: more-accurate timers, overflow checks.
2877 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2878 signal.h, setjmp.h. Include systime.h instead.
2879 (saturated_add): New function.
2880 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
2881 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
2882 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
2884 (enum profiler_cpu_running): New enum.
2885 (profiler_cpu_running): Now of that enum type, not bool.
2886 All uses changed to store the new value.
2887 (handle_profiler_signal): Rename from sigprof_handler_1,
2888 for consistency with other handlers. Do not check whether
2889 cpu_log is a hash-table if garbage collecting, since it
2890 doesn't matter in that case.
2891 (deliver_profiler_signal): Rename from sigprof_handler,
2892 for consistency with other handlers.
2893 (setup_cpu_timer): New function, with much of what used to be in
2894 Fprofiler_cpu_start. Check for out-of-range argument.
2895 Prefer timer_settime if available, and prefer
2896 thread cputime clocks, then process cputime clocks, then
2897 monotonic clocks, to the old realtime clock. Use make_timeval
2898 to round more-correctly when falling back to setitimer.
2899 (Fprofiler_cpu_start): Use it.
2900 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2901 Don't assume that passing NULL as the 2nd argument of setitimer
2902 is the same as passing a pointer to all-zero storage.
2903 Ignore SIGPROF afterwards.
2904 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2905 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2906 non-fatal signal handlers. Ignore SIGPROF on startup.
2907 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2908 in profiler.c, since sysdep.c now uses it.
2910 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
2911 Suggested by Eli Zaretskii in
2912 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2964 * character.h (MAYBE_UNIFY_CHAR): Remove.
2965 * charset.c, charset.h (maybe_unify_char): Now static.
2966 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2967 Since this stuff is now private to charset.c, there's no need for
2968 a public macro and no need to inline by hand.

3001 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
3003 Prefer POSIX timers if available.
3004 They avoid a race if the timer is too close to the current time.

3032 * w32.h (Vlibrary_cache): Do not declare.
3034 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3036 * w32proc.c (sys_signal): Handle all signals defined by the
3037 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3038 handlers for signals supported by Windows. Don't override
3039 term_ntproc as the handler for SIGABRT.
3040 (sigaction): Rewrite to call sys_signal instead of duplicating its
3042 (sys_kill): Improve commentary.
3044 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3045 consistency with a signature of a signal handler. All callers
3047 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3048 install term_ntproc as a signal handler for SIGABRT, as that
3049 should be done by the dumped Emacs.
3051 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3053 * w32select.c (term_w32select): Protect against repeated
3054 invocation by setting clipboard_owner to NULL after calling
3057 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3058 and term_ntproc to their modified signatures.
3060 * character.c (char_string, string_char): Remove calls to

3072 when encountering an unknown bytecode.
3074 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3076 image.c, indent.c: Use bool for booleans.
3077 * dispextern.h (struct image_type): Members valid_p, load, init

3079 * image.c: Omit unnecessary static decls.
3080 (x_create_bitmap_mask, x_build_heuristic_mask):

3120 (interruptible_wait_for_termination):
3121 Move these decls from lisp.h to syswait.h, since they use pid_t.
3122 Needed on FreeBSD; see Herbert J. Skuhra in
3123 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

3170 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3172 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3173 fatal_error_backtrace.
3175 * w32proc.c (sys_kill): Undo last change: don't do anything when
3176 invoked to deliver SIGABRT to our own process. This is now
3177 handled by emacs_raise.
3179 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3181 * w32term.c (w32_read_socket): Remove leftover reference to
3182 interrupt_input_pending.
3184 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3186 Do not use SA_NODEFER.
3187 Problem reported by Dani Moncayo in
3188 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3190 * sysdep.c (emacs_abort): Do not reset signal handler.
3191 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3192 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3193 wanted even on POSIXish hosts, and it doesn't work on Windows.
3195 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3197 * xterm.c (x_term_init): Call fixup_locale before and after calling
3198 gtk_init (Bug#12392).
3200 2012-09-23 Chong Yidong <cyd@gnu.org>
3202 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3203 Vdynamic_library_alist.
3205 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3206 (Fgnutls_available_p): Caller changed.
3208 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3209 (Flibxml_parse_xml_region): Likewise.
3211 * dispextern.h (struct image_type): Remove arg from init function.

3216 (init_tiff_functions, init_gif_functions, init_svg_functions):
3217 Arglist and w32_delayed_load calling convention changed.
3218 (gs_type): Remove init_gs_functions; there is no such function.
3219 (valid_image_p, make_image): Fix caller to lookup_image_type.
3221 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3223 Simplify and avoid signal-handling races (Bug#12471).
3225 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3226 Avoid recursive loop if there's a fatal error in the function itself.
3227 * atimer.c (pending_atimers):
3228 * blockinput.h: Don't include "atimer.h"; no longer needed.
3229 (interrupt_input_pending): Remove. All uses removed.
3230 pending_signals now counts both atimers and ordinary interrupts.
3231 This is less racy than having three separate pending-signal flags.
3232 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3234 Rename from their upper-case counterparts BLOCK_INPUT,
3235 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3236 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3237 This makes it easier to access volatile variables more accurately.
3238 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3239 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3240 that's more reliable if the code is buggy and sets
3241 interrupt_input_blocked to a negative value. All uses changed.
3242 * atimer.c (deliver_alarm_signal):
3243 Remove. No need to deliver this to the parent; any thread can
3244 handle this signal now. All uses replaced by underlying handler.
3245 * atimer.c (turn_on_atimers):
3246 * dispnew.c (handle_window_change_signal):
3247 * emacs.c (handle_danger_signal):
3248 * keyboard.c (kbd_buffer_get_event):
3249 Don't reestablish signal handler; not needed with sigaction.
3250 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3252 Rework to avoid unnecessary accesses to volatile variables.
3253 (UNBLOCK_INPUT_TO): Now a function.
3254 (totally_unblock_input, unblock_input): New decls.
3255 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3256 (init_data): Remove. Necessary stuff now done in init_signal.
3257 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3258 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3259 (fatal_error_code): Remove; no longer needed.
3260 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3261 it doesn't always backtrace. All uses changed. No need to reset
3262 signal to default, since sigaction and/or die does that for us now.
3263 Use emacs_raise (FOO), not kill (getpid (), FOO).
3264 (main): Check more-accurately whether we're dumping.
3265 Move fatal-error setup to sysdep.c
3266 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3267 * gtkutil.c (xg_get_file_name, xg_get_font):
3268 Remove no-longer-needed signal-mask manipulation.
3269 * keyboard.c, process.c (POLL_FOR_INPUT):
3270 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3271 * keyboard.c (read_avail_input): Remove.
3272 All uses replaced by gobble_input.
3273 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3274 (kbd_buffer_store_event_hold, gobble_input):
3275 (record_asynch_buffer_change) [USABLE_SIGIO]:
3276 (store_user_signal_events):
3277 No need to mess with signal mask.
3278 (gobble_input): If blocking input and there are terminals, simply
3279 set pending_signals to 1 and return. All hooks changed to not
3280 worry about whether input is blocked.
3281 (process_pending_signals): Clear pending_signals before processing
3282 them, in case a signal comes in while we're processing.
3283 By convention callers now test pending_signals before calling us.
3284 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3285 New functions, to support changes to blockinput.h.
3286 (handle_input_available_signal): Now extern.
3287 (reinvoke_input_signal): Remove. All uses replaced by
3289 (quit_count): Now volatile, since a signal handler uses it.
3290 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3291 All callers changed. Block SIGINT only if not already blocked.
3292 Clear sigmask reliably, even if Fsignal returns, which it can.
3293 Omit unnecessary accesses to volatile var.
3294 (quit_throw_to_read_char): No need to restore sigmask.
3295 * keyboard.c (gobble_input, handle_user_signal):
3296 * process.c (wait_reading_process_output):
3297 Call signal-handling code rather than killing ourselves.
3298 * lisp.h: Include <float.h>, for...
3299 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3300 (pending_signals): Now volatile.
3301 (syms_of_data): Now const if IEEE floating point.
3302 (handle_input_available_signal) [USABLE_SIGIO]:
3303 (terminate_due_to_signal, record_child_status_change): New decls.
3304 * process.c (create_process): Avoid disaster if memory is exhausted
3305 while we're processing a vfork, by tightening the critical section
3307 (send_process_frame, process_sent_to, handle_pipe_signal)
3308 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3310 (send_process): No need for setjmp/longjmp any more, since the
3311 SIGPIPE stuff is now gone. Instead, report an error if errno
3313 (record_child_status_change): Now extern. PID and W are now args.
3314 Return void, not bool. All callers changed.
3315 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3316 Remove. All uses removed. This bug should be fixed now in a
3318 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3319 and record the child status change directly. This avoids the
3320 need to futz with the signal mask.
3321 (process_fatal_action): Move here from emacs.c.
3322 (emacs_sigaction_flags): New function, containing
3323 much of what used to be in emacs_sigaction_init.
3324 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3325 caught by emacs, to make races less likely.
3326 (deliver_process_signal): Rename from handle_on_main_thread.
3328 (BACKTRACE_LIMIT_MAX): Now at top level.
3329 (thread_backtrace_buffer, threadback_backtrace_pointers):
3331 (deliver_thread_signal, deliver_fatal_thread_signal):
3332 New functions, for more-accurate delivery of thread-specific signals.
3333 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3334 (deliver_arith_signal): Handle in this thread, not
3335 in the main thread, since it's triggered by this thread.
3336 (maybe_fatal_sig): New function.
3337 (init_signals): New arg DUMPING so that we can be more accurate
3338 about whether we're dumping. Caller changed.
3339 Treat thread-specific signals differently from process-general signals.
3340 Block all signals while handling fatal error; that's safer.
3341 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3343 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3344 Ignore SIGPIPE unless batch.
3345 (emacs_backtrace): Output backtrace for the appropriate thread,
3346 which is not necessarily the main thread.
3347 * syssignal.h: Include <stdbool.h>.
3348 (emacs_raise): New macro.
3349 * xterm.c (x_connection_signal): Remove; no longer needed
3350 now that we use sigaction.
3351 (x_connection_closed): No need to mess with sigmask now.
3352 (x_initialize): No need to reset SIGPIPE handler here, since
3353 init_signals does this for us now.
3355 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3357 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3358 background rect may be larger (Bug#12245).
3360 2012-09-23 Chong Yidong <cyd@gnu.org>
3362 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3364 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3366 * .gdbinit: Just stop at fatal_error_backtrace.
3367 See Stefan Monnier's request in
3368 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3369 Remove no-longer-used query of system type.
3371 2012-09-22 Chong Yidong <cyd@gnu.org>
3373 * search.c (Freplace_match): Doc fix (Bug#12325).
3375 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3377 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3378 (Fline_end_position): Doc fix.
3380 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3382 2012-09-22 Chong Yidong <cyd@gnu.org>
3384 * dispextern.h (struct image_type): Add new slot, storing a type
3385 initialization function.
3387 * image.c (define_image_type): Call the image initializer function
3388 if it is defined. Arguments and return value changed.
3389 (valid_image_p, make_image): Callers changed.
3390 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3391 (gif_type, imagemagick_type, svg_type, gs_type):
3392 Add initialization functions.
3393 (Finit_image_library): Call lookup_image_type.
3394 (CHECK_LIB_AVAILABLE): Macro deleted.
3395 (lookup_image_type): Call define_image_type here, rather than via
3396 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3397 (syms_of_image): Move define_image_type calls for xbm_type and
3398 pbm_type to lookup_image_type.
3400 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3402 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3403 'idle_timers' from here ...
3404 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3405 lists, to avoid infloops when the timer does something stupid,
3406 like reinvoke itself with the same or smaller time-out.
3409 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3411 * window.c (Fsplit_window_internal): Handle only Qt value of
3412 Vwindow_combination_limit separately.
3413 (Qtemp_buffer_resize): New symbol.
3414 (Vwindow_combination_limit): New default value.
3417 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3419 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3420 the new overlay string. (Bug#10159)
3422 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3424 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3425 or that fprintf is async-signal-safe. POSIX doesn't require
3428 2012-09-22 Chong Yidong <cyd@gnu.org>
3430 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3433 2012-09-22 Kenichi Handa <handa@gnu.org>
3435 * composite.c (composition_reseat_it): Handle the case that a
3436 grapheme cluster is not covered by a single font (Bug#12352).
3438 2012-09-21 Chong Yidong <cyd@gnu.org>
3440 * image.c (define_image_type): Avoid adding duplicate types to
3441 image_types (Bug#12463). Suggested by Jörg Walter.
3443 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3445 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3446 (print_load_command_name): Add case LC_DATA_IN_CODE.
3447 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3449 2012-09-21 Glenn Morris <rgm@gnu.org>
3451 * eval.c (Frun_hook_with_args_until_success)
3452 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3454 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3456 * fileio.c (Ffile_selinux_context): Only call freecon when
3457 lgetfilecon succeeded.
3458 (Fset_file_selinux_context): Likewise. (Bug#12444)
3460 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3462 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3463 reordering, locate the cursor by calling set_cursor_from_row; if
3464 that fails, clear the desired glyph matrix before returning a
3465 failure indication to the caller. Fixes leaving garbled display
3466 when fast scrolling with a down-key. (Bug#12403)
3467 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3468 scrolling through multibyte text.
3470 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3472 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3473 calling mark_vectorlike since that's the one that marks the window.
3474 (mark_discard_killed_buffers): Mark the final cdr.
3475 * window.h (struct window): Move prev/next_buffers to the
3476 non-standard fields.
3477 * window.c (make_window): Initialize prev/next_buffers manually.
3479 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3481 Omit unused arg EXPECTED from socket hooks.
3482 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3483 * nsterm.m (ns_term_init):
3484 * termhooks.h (struct terminal.read_socket_hook):
3485 * w32inevt.c (w32_console_read_socket):
3486 * w32term.c (w32_read_socket):
3487 * xterm.c (XTread_socket):
3488 Omit unused arg EXPECTED. All callers changed.
3489 (store_user_signal_events): Return void, not int, since callers no
3490 longer care about the return value. All uses changed.
3492 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3494 * w32gui.h (XParseGeometry): Do not declare.
3496 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3498 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3499 Ignore 'expected'. See Eli Zaretskii in
3500 <http://bugs.gnu.org/12471#8> (last line).
3502 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3503 (XParseGeometry): Now static. Substitute extremal values for
3504 values that are out of range.
3506 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3508 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3510 * nsfns.m (XParseGeometry): Remove.
3511 (Fx_create_frame): Call x_set_offset to correctly interpret
3512 top_pos in geometry.
3514 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3515 (Fx_parse_geometry): If there is a space in string, call
3516 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3518 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3520 * search.c (scan_buffer): Use character positions in calls to
3521 region_cache_forward and region_cache_backward, not byte
3522 positions. (Bug#12196)
3524 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3525 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3527 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3528 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3529 emacs_blocked_malloc, now deleted.
3531 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3533 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3534 The workaround was for improving performance on Solaris 2.4, but
3535 is getting in the way now. Emacs will still work if someone is
3536 still running Solaris 2.4 in a museum somewhere; Sun dropped
3537 support for Solaris 2.4 in 2003.
3538 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3539 * process.c (create_process) [HAVE_WORKING_VFORK]:
3540 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3541 since Emacs no longer uses vfork on that platform.
3543 2012-09-17 Glenn Morris <rgm@gnu.org>
3545 * emacs.c: Use COPYRIGHT.
3547 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3549 Remove configure's --without-sync-input option (Bug#12450).
3550 When auditing signal-handling in preparation for cleaning it up,
3551 I found that SYNC_INPUT has race conditions and would be a real
3552 pain to fix. Since it's an undocumented and deprecated
3553 configure-time option, now seems like a good time to remove it.
3554 Also see <http://bugs.gnu.org/11080#16>.
3555 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3556 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3557 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3558 (malloc_hysteresis):
3559 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3560 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3561 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3562 (dont_register_blocks, bytes_used_when_reconsidered)
3563 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3564 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3565 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3566 Remove. All uses removed.
3567 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3568 implementation, one that depends on whether the new macro
3569 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3571 * atimer.c (run_timers, handle_alarm_signal):
3572 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3573 (handle_async_input, process_pending_signals)
3574 (handle_input_available_signal, init_keyboard):
3575 * nsterm.m (ns_read_socket):
3576 * process.c (wait_reading_process_output):
3577 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3578 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3580 * xterm.c (XTread_socket):
3582 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3583 * eval.c (handling_signal): Remove. All uses removed.
3584 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3585 All uses replaced with the SYNC_INPUT version.
3586 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3588 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3591 * font.c (Ffont_shape_gstring): Remove unused local.
3593 2012-09-16 Glenn Morris <rgm@gnu.org>
3595 * Makefile.in (clean): No longer run nextstep's clean.
3597 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3599 (ns-app): Move here from ns.mk, and simplify.
3600 (clean): Simplify nextstep entry.
3601 * ns.mk: Remove file.
3603 2012-09-17 Kenichi Handa <handa@gnu.org>
3605 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3606 not covert the last few charactes.
3608 2012-09-16 Kenichi Handa <handa@gnu.org>
3610 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3611 here, but just check the validity of glyphs in the glyph-string.
3613 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3615 * window.c (Fwindow_parameter, Fset_window_parameter):
3616 Accept any window as argument (Bug#12452).
3618 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3620 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3621 to ns_term_init to avoid memory leak.
3623 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3624 explicit retain/release.
3625 (ns_term_init): Only allow one display. Initialize outerpool and
3628 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3630 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3631 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3632 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3633 the Microsoft problem in a different way, by altering ../nt/config.nt.
3635 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3650 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3651 by lisp.h. This completes removal of setjmp.h inclusion
3652 erroneously announced in the previous commit. (Bug#12446)
3654 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3657 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3658 not defined as a macro. The latter happens on MS-Windows.
3661 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3663 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3664 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3665 Some instances of '#include <setjmp.h>' removed, if the
3666 only reason for the instance was because "lisp.h" was included.
3667 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3668 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3669 and _longjmp with the new symbols. Emacs already uses _setjmp if
3670 available, so this change affects only POSIXish hosts that have
3671 sigsetjmp but not _setjmp, such as some versions of Solaris and
3672 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3673 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3674 (png_load_body) [HAVE_PNG]:
3675 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3676 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3677 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3678 since PNG requires jmp_buf. This is the only exception to the
3679 general rule that we now use sys_setjmp and sys_longjmp.
3680 This exception is OK since this code does not change the signal
3681 mask or longjmp out of a signal handler.
3683 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3685 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3686 Include "syssignal.h", for 'main_thread'.
3688 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3690 Avoid out-of-range marker position (Bug#12426).
3691 * insdel.c (replace_range, replace_range_2):
3692 Adjust markers before overlays, as suggested by comments.
3693 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3694 Remove redundant check before calling offset_intervals.
3696 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3698 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3699 current buffer (Bug#12387).
3701 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3703 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3705 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3707 Use a more backwards-compatible timer format (Bug#12430).
3708 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3709 vector element, not from the 4th, since PSECS is now at the end.
3710 (Fcurrent_idle_time): Doc fix.
3712 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3714 Function to mark objects and remove killed buffers at once.
3715 * alloc.c (discard_killed_buffers): Rename to ...
3716 (mark_discard_killed buffers) ... new name. Add marking
3717 of remaining objects. Fix comment. Adjust users.
3718 (mark_object): Do not touch frame buffer lists here.
3719 * frame.c (delete_frame): Reset frame buffer lists here.
3721 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3723 Better workaround for GNOME bug when --enable-gcc-warnings.
3724 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3725 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3726 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3728 Simplify SIGIO usage (Bug#12408).
3729 The code that dealt with SIGIO was crufty and confusing, e.g., it
3730 played tricks like "#undef SIGIO" but these tricks were not used
3731 consistently. Simplify mostly by not #undeffing standard symbols,
3732 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3733 or not as we please) rather than "defined SIGIO" (standard symbol
3734 that we probably shouldn't #undef).
3735 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3736 Modules that need it can include it.
3737 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3738 * dispextern.h (ignore_sigio): New decl.
3739 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3740 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3741 * emacs.c (shut_down_emacs):
3742 * keyboard.c (kbd_buffer_store_event_hold):
3743 Use ignore_sigio rather than invoking 'signal' directly.
3744 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3746 (FIONREAD, SIGIO): Do not #undef.
3747 (tty_read_avail_input): Use #error rather than a syntax error.
3748 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3749 for I_PIPE, used by SETUP_SLAVE_PTY.
3750 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3751 * sysdep.c (croak): Remove; no longer needed. This bit of
3752 temporary code, with Fred N. Fish's comment that it's temporary,
3753 has been in Emacs since at least 1992!
3754 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3755 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3756 * syssignal.h (croak): Remove decl.
3757 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3758 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3759 now that we're termios-only.
3760 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3761 * term.c (dissociate_if_controlling_tty): Use #error rather than
3764 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3765 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3766 to work around GNOME bug 683906.
3767 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3768 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3769 This works around GCC bug 54561.
3771 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3773 More fixes for 'volatile' and setjmp/longjmp.
3774 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3775 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3776 (png_load_body) [HAVE_PNG]:
3777 (jpeg_load_body) [HAVE_JPEG]:
3778 New function, with most of the old parent function's body.
3779 (png_load) [HAVE_PNG]:
3780 (jpeg_load) [HAVE_JPEG]:
3781 Invoke the new function, to avoid longjmp munging our locals.
3782 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3783 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3784 longjmp is passed 2, as the C standard doesn't guarantee this.
3785 Instead, store the failure code into mgr->failure_code.
3787 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3789 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3790 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3791 (syms_of_keyboard): Remove support for unread-command-char.
3793 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3795 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3796 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3797 violation. (Bug#12426)
3799 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3801 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3803 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3805 * eval.c: Add `inhibit-debugger'.
3806 (Qinhibit_debugger): New symbol.
3807 (call_debugger): Bind it instead of Qdebug_on_error.
3808 (maybe_call_debugger): Test Vinhibit_debugger.
3809 (syms_of_eval): Define inhibit-debugger.
3810 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3811 (syms_of_xdisp): Remove inhibit-debug-on-message.
3813 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3815 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3816 If a nonvolatile local variable is written before a _longjmp to
3817 the frame containing the variable, and is read after the _longjmp,
3818 the value read is indeterminate. Some local variables of type
3819 'struct handler' and 'struct catchtag' are used in this way, so
3820 mark each of their slots as volatile if the slot can be set before
3821 _longjmp and read afterwards.
3822 * lisp.h (struct handler): var and chosen_clause are now volatile.
3823 (struct catchtag): val, next, and pdlcount are now volatile.
3825 * bidi.c (bidi_push_it, bidi_pop_it):
3826 * fns.c (copy_hash_table):
3827 * image.c (define_image_type):
3828 * keyboard.c (kbd_buffer_store_event_hold):
3829 * process.c (Fprocess_send_eof):
3830 * xfaces.c (x_create_gc) [HAVE_NS]:
3831 * xgselect.c (xg_select):
3832 Prefer assignment to memcpy when either will do.
3834 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3835 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3836 time an item is removed. No need to mark this function 'inline';
3837 the compiler knows better than we do.
3839 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3841 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3842 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3843 to change_frame_size (Bug#12388).
3844 (windowDidResize:): Pass YES to updateFrameSize.
3846 * nsterm.h: Add delay parameter to updateFrameSize.
3848 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3850 Discard killed buffers from deleted window and frame objects.
3851 This reduces an amount of references to killed buffers and
3852 helps GC to reclaim them faster.
3853 * alloc.c (discard_killed_buffers): New function.
3854 (mark_object): Use it for deleted windows and frames.
3855 (mark_object): If symbol's value is set up for a killed buffer
3856 or deleted frame, restore its global binding.
3857 * data.c (swap_in_global_binding): Add GC notice.
3858 (swap_in_symval_forwarding): Use convenient set_blv_where.
3859 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3860 * window.h: ... to here.
3862 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3864 Convenient macro to check whether the buffer is live.
3865 * buffer.h (BUFFER_LIVE_P): New macro.
3866 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3867 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3869 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3871 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3872 composition cases (Bug#12364).
3874 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3875 overhang of succeeding glyphs overlapping box cursor.
3877 * w32term.c (x_draw_glyph_string): Likewise.
3879 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3881 Simplify, document, and port floating-point (Bug#12381).
3882 The porting part of this patch fixes bugs on non-IEEE platforms
3883 with frexp, ldexp, logb.
3884 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3886 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3887 support, by removing commented-out code and briefly listing the
3888 C89 functions excluded. The commented-out stuff was confusing
3889 maintenance, e.g., we thought we needed cbrt but it was commented out.
3890 (logb): Remove decl; no longer needed.
3891 (isfinite): New macro, if not already supplied.
3892 (isnan): Don't replace any existing macro.
3893 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3894 are present on all C89 platforms.
3895 (Ffrexp): Do not special-case zero, as frexp does the right thing
3897 (Flogb): Do not use logb, as it doesn't have the desired meaning
3898 on hosts that use non-base-2 floating point. Instead, stick with
3899 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3900 frexp, to avoid getting an unspecified result.
3902 * xdisp.c (Qinhibit_debug_on_message): Now static.
3904 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3906 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3907 NSBezierPath (Bug#12131).
3909 2012-09-10 Chong Yidong <cyd@gnu.org>
3911 * fns.c (Fdelq, Fdelete): Doc fix.
3913 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3915 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3916 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3918 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3920 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3921 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3924 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3926 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3927 left fringe if the window has a left margin. This avoids leaving
3928 traces of the cursor because its leftmost pixel is not drawn over.
3930 * dispnew.c (update_window_line): When the left margin area of a
3931 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3932 that screen line. (Bug#12277)
3934 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3936 Assume C89 or later for math functions (Bug#12381).
3937 This simplifies the code, and makes it a bit smaller and faster,
3938 and (most important) makes it easier to clean up signal handling
3939 since we can stop worring about floating-point exceptions in
3940 library code. That was a problem before C89, but the problem
3941 went away many years ago on all practical Emacs targets.
3942 * data.c, image.c, lread.c, print.c:
3943 Don't include <math.h>; no longer needed.
3944 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3945 might be autoconfigured, as that never happens.
3947 * doprnt.c (DBL_MAX_10_EXP):
3948 * print.c (DBL_DIG):
3949 Remove. C89 or later always defines these.
3950 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3951 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3952 (arith_error, domain_error, domain_error2):
3953 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3954 no longer needed -- we simply return what C returns. All uses removed.
3955 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3957 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3958 Remove. All uses expanded, as these macros are no longer used
3959 more than once and are now more trouble than they're worth.
3960 (Ftan): Use tan, not sin / cos.
3961 (Flogb): Assume C89 frexp.
3962 (fmod_float): Assume C89 fmod.
3963 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3964 (init_floatfns): Remove. All uses removed.
3966 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3968 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3969 compositeToPoint for OSX < 10.6 (Bug#12390).
3971 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3973 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3974 This produces more-accurate results.
3976 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3978 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3979 changes (Bug#12088).
3981 2012-09-08 Chong Yidong <cyd@gnu.org>
3983 * syntax.c (Fstring_to_syntax): Doc fix.
3985 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3987 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3988 in the internal border.
3989 (x_set_window_size): Remove static variables and their usage.
3990 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3991 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3992 Remove fringe/internal border adjustment (Bug#11052).
3993 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3994 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3995 (ns_fix_rect_ibw): Remove.
3996 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3997 (ns_dumpglyphs_box_or_relief): Ditto.
3998 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4000 (ns_dumpglyphs_image): Ditto.
4001 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4003 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4004 their usage. Add fringe_extended_p and its use as in other terms.
4005 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4006 scroll bar was removed.
4007 (updateFrameSize): New function.
4008 (windowDidResize): Move code to updateFrameSize and call it.
4010 * nsterm.h (EmacsView): Add updateFrameSize.
4012 2012-09-07 Chong Yidong <cyd@gnu.org>
4014 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4016 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4018 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4020 More signal-handler cleanup (Bug#12327).
4021 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4022 Problem introduced when merging patches. Noted by Eli Zaretskii in
4023 <http://bugs.gnu.org/12327#67>.
4024 * floatfns.c: Comment fix.
4025 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4026 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4027 and anyway the declaration is harmless even if SIGDANGER is not defined.
4028 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4029 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4030 source files not surprisingly expected syssignal.h to define, or
4031 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4032 Include <sys/ioctl.h>, for FIONREAD.
4033 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4034 This eliminates a problem whereby other files mysteriously had
4035 to include "syssignal.h" before including "systty.h" if they
4036 wanted to use "#ifdef SIGIO".
4038 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4040 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4042 * w32.c (sigemptyset): Empty the set.
4043 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4045 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4047 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4049 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4050 (mark_object): Likewise for frame objects.
4052 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4054 * syssignal.h (handle_on_main_thread): Always declare,
4055 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4056 This ports to platforms without HAVE_PTHREAD.
4058 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4060 Signal-handler cleanup (Bug#12327).
4061 Emacs's signal handlers were written in the old 4.2BSD style with
4062 sigblock and sigmask and so forth, and this led to some
4063 inefficiencies and confusion. Rewrite these to use
4064 pthread_sigmask etc. without copying signal sets around. Also,
4065 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4066 'signal', and instead use functions that do not attempt to take
4067 over the system name space. This patch causes Emacs's text
4068 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4069 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4070 Do not include <signal.h> or "syssignal.h", as these
4071 modules do not use signals.
4072 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4073 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4074 Do not include <signal.h>, as "syssignal.h" does that for us now.
4075 * atimer.c (sigmask_atimers): New function.
4076 (block_atimers, unblock_atimers): New functions,
4077 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4079 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4080 no longer needed here.
4081 * emacs.c (main): Inspect existing signal handler with sigaction,
4082 so that there's no need to block and unblock SIGHUP.
4083 * sysdep.c (struct save_signal): New member 'action', replacing
4084 old member 'handler'.
4085 (save_signal_handlers, restore_signal_handlers):
4086 Use sigaction instead of 'signal' to save and restore.
4087 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4088 New function. All users of 'signal' modified to use set_sighandler
4089 if they're writeonly, and to use sys_signal if they're read+write.
4090 (emacs_sigaction_init, forwarded_signal): New functions.
4091 (sys_signal): Remove. All uses replaced by calls to sigaction
4092 and emacs_sigaction_init, or by direct calls to 'signal'.
4093 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4094 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4095 all uses replaced by pthread_sigmask etc. calls.
4096 * syssignal.h: Include <signal.h>.
4097 (emacs_sigaction_init, forwarded_signal): New decls.
4098 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4099 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4100 (sigmask, sys_sigmask): Remove; no longer needed.
4101 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4102 (sigblock, sigunblock, sigfree):
4103 (sigsetmask) [!defined sigsetmask]:
4104 Remove. All uses replaced by pthread_sigmask.
4105 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4106 no longer need to be replaced, and its typical old uses
4107 are now done via emacs_sigaction_init and sigaction.
4108 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4109 (sys_sigdel): Remove; unused.
4110 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4112 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4114 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4115 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4117 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4119 Explicitly mark buffer_defaults and buffer_local_symbols.
4120 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4121 mark_local_symbols here.
4122 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4123 since special buffers aren't marked here any more.
4124 (allocate_buffer): Chain new buffer with all_buffers here...
4125 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4127 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4128 (syms_of_buffer): Remove staticpro of the above.
4129 (init_buffer_once): Set names for buffer_defaults and
4130 buffer_local_symbols.
4132 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4134 Use bool for booleans in font-related modules.
4135 * font.c (font_intern_prop, font_style_to_value)
4136 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4137 (generate_otf_features, font_check_otf_features, font_check_otf)
4138 (font_match_p, font_list_entities, font_at):
4139 * fontset.c (fontset_id_valid_p, reorder_font_vector
4140 (fontset_find_font, Fset_fontset_font)
4141 (face_suitable_for_char_p) [0]:
4142 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4143 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4144 (m17n_flt_initialized, ftfont_shape_by_flt):
4145 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4146 * nsfont.m (nsfont_draw):
4147 * w32font.c (w32font_draw):
4148 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4149 Use bool for booleans.
4150 * font.h: Adjust to above API changes.
4151 (struct font, struct font_driver, struct font_driver_list):
4152 Use bool for booleans.
4153 (struct font): Remove useless member encoding_type.
4155 * fontset.c, xftfont.c: Omit unnecessary static decls.
4157 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4159 * alloc.c (mark_object): Revert window marking code
4160 since it's unsafe for the Fset_window_configuration.
4162 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4164 Fix race conditions with signal handlers and errno (Bug#12327).
4165 Be more systematic about preserving errno whenever a signal
4166 handler returns, even if it's not in the main thread. Do this by
4167 renaming signal handlers to distinguish between signal delivery
4168 and signal handling. All uses changed.
4169 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4170 * data.c (deliver_arith_signal): Rename from arith_error.
4171 * dispnew.c (deliver_window_change_signal): Rename from
4172 window_change_signal.
4173 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4174 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4175 * keyboard.c (deliver_input_available_signal): Rename from
4176 input_available_signal.
4177 (deliver_user_signal): Rename from handle_user_signal.
4178 (deliver_interrupt_signal): Rename from interrupt_signal.
4179 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4180 (deliver_child_signal): Rename from sigchld_handler.
4181 * atimer.c (handle_alarm_signal):
4182 * data.c (handle_arith_signal):
4183 * dispnew.c (handle_window_change_signal):
4184 * emacs.c (handle_fatal_signal, handle_danger_signal):
4185 * keyboard.c (handle_input_available_signal):
4186 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4187 * process.c (handle_pipe_signal, handle_child_signal):
4188 New functions, with the actual signal-handling code taken from the
4189 original respective signal handlers, sans the sporadic attempts to
4190 preserve errno, since that's now done by handle_on_main_thread.
4191 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4192 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4193 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4195 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4196 Move initialization of main_thread to sysdep.c's init_signals.
4197 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4198 our usage, and simplifies the mainline code.
4199 (record_child_status_change): New static function, as a helper
4200 for handle_child_signal, and with most of the old child handler's
4202 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4203 (handle_child_signal): Use the above.
4204 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4205 Moved here from emacs.c.
4206 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4207 code moved here from emacs.c's main function.
4208 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4209 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4210 This lets callers save and restore errno properly.
4212 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4214 Remove redundant or unused things here and there.
4215 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4216 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4217 * editfns.c (Fcompare_buffer_substrings): Likewise.
4218 * frame.h (struct terminal, struct font_driver_list):
4219 Remove redundant declarations.
4220 * window.h (Qleft, Qright): Likewise.
4222 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4224 Do not mark objects from deleted buffers, windows and frames.
4225 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4226 (mark_object): Likewise for windows and frames.
4228 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4230 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4231 buffer_defaults and buffer_local_symbols as valid objects.
4232 Return special value to denote them.
4234 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4236 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4237 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4238 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4239 (file_name_absolute_p, Fsubstitute_in_file_name):
4240 (check_executable, check_writable, Ffile_accessible_directory_p)
4241 (Fset_file_selinux_context, Fdefault_file_modes)
4242 (Finsert_file_contents, choose_write_coding_system)
4243 (Fwrite_region, build_annotations, a_write, e_write)
4245 * filelock.c (boot_time_initialized, get_boot_time)
4246 (get_boot_time_1, lock_file_1, within_one_second):
4247 * floatfns.c (in_float):
4248 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4249 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4250 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4251 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4252 * window.c (compare_window_configurations):
4253 Use bool for booleans.
4254 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4255 (Fdefault_file_modes): Now mode_t, not int, for modes.
4256 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4257 (internal_delete_file): Now returns void, not a (boolean) int,
4258 since nobody was looking at the return value.
4259 * lisp.h, window.h: Adjust to above API changes.
4261 * xdisp.c (set_message): Simplify and reindent last change.
4263 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4265 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4267 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4269 * eval.c (call_debugger): Make the function non-static so that we
4270 can call it from set_message.
4272 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4273 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4275 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4277 Give more-useful info on a fatal error (Bug#12328).
4278 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4279 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4280 of doing the work ourselves.
4281 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4282 do most of the work.
4283 (fatal_error_backtrace): New function, taken from the guts
4284 of the old fatal_error_signal, but with a new option to output
4286 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4287 info about the signal than just its number.
4288 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4289 * sysdep.c: Include <execinfo.h>
4290 (emacs_backtrace): New function, taken partly from the previous
4291 code of the 'die' function.
4292 (emacs_abort): Call fatal_error_backtrace rather than abort.
4294 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4296 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4297 eager (load-time) macro-expansion.
4298 * lisp.mk (lisp): Add macroexp.
4300 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4302 Simplify redefinition of 'abort' (Bug#12316).
4303 Do not try to redefine the 'abort' function. Instead, redo
4304 the code so that it calls 'emacs_abort' rather than 'abort'.
4305 This removes the need for the NO_ABORT configure-time macro
4306 and makes it easier to change the abort code to do a backtrace.
4307 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4308 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4309 Remove; sysdep.c's emacs_abort now takes its place.
4310 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4311 'abort' changed to use 'emacs_abort'.
4312 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4313 (abort) [!defined abort]: Rename to ...
4314 (emacs_abort): ... new name.
4315 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4316 the place of the old 'abort' in emacs.c.
4317 * w32.c, w32fns.c (abort): Do not #undef.
4318 * w32.c (emacs_abort): Rename from w32_abort.
4320 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4322 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4323 offsets[j].dv, since the y axis of the screen coordinates points
4324 down, while the y axis of the font definition coordinates points
4325 up. This fixes display of Arabic diacritics such as KASRA and
4326 KASRATAN. (Bug#11860)
4328 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4330 Be more systematic about _setjmp vs setjmp.
4331 * alloc.c (test_setjmp, mark_stack):
4332 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4333 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4334 (png_load, my_error_exit, jpeg_load):
4335 * process.c (send_process_trap, send_process):
4336 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4337 The underscored versions are up to 30x faster on some hosts.
4338 Formerly, the code used setjmp+longjmp sometimes and
4339 _setjmp+_longjmp at other times, with no particular reason to
4340 prefer setjmp+longjmp.
4342 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4344 Fix minor problem found by static checking.
4345 * buffer.c (Fdelete_all_overlays): Return nil.
4347 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4349 * buffer.c (Fdelete_all_overlays): New function.
4351 2012-09-03 Chong Yidong <cyd@gnu.org>
4353 * gtkutil.c: Add extern decl for Qxft.
4355 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4357 * emacs.c, eval.c: Use bool for boolean.
4358 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4359 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4360 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4361 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4362 (main, decode_env_path, Fdaemon_initialized):
4363 * eval.c (call_debugger, Finteractive_p, interactive_p):
4364 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4365 (maybe_call_debugger, Fbacktrace):
4366 * process.c (read_process_output, exec_sentinel):
4367 Use bool for booleans.
4368 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4369 All callers changed.
4370 * eval.c (interactive_p): Omit always-true boolean argument
4371 EXCLUDE_SUBRS_P. All callers changed.
4372 * dispextern.h, lisp.h: Reflect above API changes.
4373 * firstfile.c (dummy): Use the address of 'main', whose signature
4374 won't change, instead of the address of 'initialize', whose
4375 signature just changed from int to bool.
4376 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4377 * msdos.c (fatal_error_in_progress): ... from here.
4378 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4380 (redisplay_internal, unwind_redisplay): Simply clear
4381 REDISPLAYING_P when unwinding, instead of saving its previous,
4382 always-false value and then restoring it.
4384 Clean up some extern decls.
4385 Mostly, this hoists extern decls out of .c files and into .h files.
4386 That way, we're more likely to catch errors if the interfaces change.
4387 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4388 declare xg_mark_data.
4389 * dispextern.h (x_frame_parm_handlers):
4391 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4392 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4393 (Qultra_bold, Qoblique, Qitalic):
4394 Move extern decl here from .c file.
4395 * alloc.c (xg_mark_data) [USE_GTK]:
4397 * eval.c (Qlexical_binding):
4398 * fns.c (time) [!HAVE_UNISTD_H]:

4404 * process.c (QCfamily, QCfilter):
4405 * widget.c (free_frame_faces):
4406 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4407 * xfont.c (x_clear_errors):
4408 * xterm.c (x_frame_parm_handlers):
4409 Remove now-redundant extern decls.
4410 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4411 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4413 * xfaces.c: Remove unnecessary static decls.
4414 * xterm.c (updating_frame): Remove decl of nonexistent object.
4416 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4417 when building globals.h, as the objects that are not built on
4418 this host are not needed to compile C files on this host.
4420 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4422 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4424 * frame.h: Add missing prototype for x_wm_set_size_hint.
4426 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4436 (make_buffer_string, make_buffer_string_both)
4437 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

4457 * keymap.c (push_key_description): Print M-TAB as C-M-i
4460 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4462 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4463 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

4468 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4470 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4472 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4473 more than one grapheme cluster passed to the shaper: compute the
4474 offset adjustment values separately for each cluster. (Bug#11860)
4476 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4477 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4478 about implicit conversions from integer to pointer.
4480 2012-09-01 Daniel Colascione <dancol@dancol.org>
4482 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4483 system used too early.
4485 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4487 Better seed support for (random).
4488 * emacs.c (main): Call init_random.
4489 * fns.c (Frandom): Set the seed from a string argument, if given.
4490 Remove long-obsolete Gentzel cruft.

4496 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
4497 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
4498 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,

4500 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4501 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
4502 all of which have been moved to common code.
4504 * xfaces.c: Include TERM_HEADER instead of listing all possible
4505 window-system headers.
4507 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
4510 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
4511 directly accessing frame internals.
4513 * w32font.h: Include font.h. Define syms_of_w32font and
4516 * process.c: Include TERM_HEADER instead of listing all possible
4517 window-system headers.
4519 * nsterm.h: Remove declarations now in frame.h.
4520 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
4522 * menu.c: Include TERM_HEADER instead of listing all possible
4523 window-system headers.
4525 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4528 * keyboard.c: Include TERM_HEADER instead of listing all possible
4529 window-system headers.
4531 * image.c: Include TERM_HEADER instead of listing all possible
4532 window-system headers. Declare Vlibrary_cache when compiling for
4535 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4536 window system declarations.
4538 * frame.h: Move common functions here: set_frame_menubar,
4539 x_set_window_size, x_sync, x_get_focus_frame,
4540 x_set_mouse_position, x_set_mouse_pixel_position,
4541 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4567 Remove mark_ttys function and fix tty_display_info initialization.
4568 * lisp.h (mark_ttys): Remove prototype.
4569 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4570 to mark_ttys because all possible values of 'top_frame' slot are
4571 the frames which are reachable from Vframe_list.
4572 * term.c (mark_ttys): Remove.
4573 (init_tty): Safely initialize 'top_frame' slot with Qnil.

4581 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
4582 bitfields from unsigned char to unsigned.

4586 Remove unused member of struct x_output and struct w32_output.
4587 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
4588 * w32term.h (struct w32_output): Likewise.
4590 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
4592 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4593 does not become zero (Bug#12234).
4595 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
4597 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4598 for GCC 4.7.1 x86-64.

4603 source directory's site-lisp dir to the load-path if it exists,
4604 consistent with in-tree builds. (Bug#12302)
4606 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
4608 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
4609 button_values to NULL. Call setStykeMask so dialogs get a close button.
4610 (windowShouldClose:): Set window_closed.
4611 (dealloc): New member, free button_values.
4612 (process_dialog:): Make member function. Remove window argument,
4613 replace window with self. Count buttons and allocate and store values

4622 Code formatting change.
4623 (timeout_handler:): Set timer_fired to YES.
4624 (runDialogAt:): Set timer_fired to NO.
4625 Handle click on close button as quit.
4627 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4628 Add window_closed and button_values. Add void as return value for
4629 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4630 Add process_dialog as new member.
4632 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4634 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
4635 is not one of the heaps we manage. (Bug#12242)
4637 2012-08-28 Glenn Morris <rgm@gnu.org>
4639 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

4651 if the buffer is dead.
4652 (Fother_buffer, other_buffer_safely): Remove redundant
4655 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4657 Always use set_buffer_if_live to restore original buffer at unwind.

4695 (change_frame_size_1, sit_for):
4696 Use bool for boolean.
4697 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
4698 and remove last int (actually boolean) argument, which was always 0.
4699 All callers changed.
4700 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
4701 * dispextern.h (struct composition_it): Use bool for boolean.
4702 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
4703 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
4704 * dired.c (file_name_completion):
4705 Use bool for boolean. (This was missed in an earlier change.)
4707 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4709 * window.c (Fset_window_configuration): Revert first part of
4712 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
4714 * nsterm.h (NSPanel): New class variable dialog_return.
4716 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
4717 Initialize dialog_return.
4718 (windowShouldClose:): Use stop instead of stopModalWithCode.
4719 (clicked:): Ditto, and also set dialog_return (Bug#12258).
4720 (timeout_handler:): Use stop instead of abortModal. Send a dummy
4722 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

4737 Use bool for booleans.
4738 * dired.c (file_name_completion):
4739 * process.h (fd_callback):
4740 Omit int (actually boolean) argument. It wasn't being used.

4767 Use bool for booleans.
4768 * coding.h, lisp.h: Reflect above API changes.
4769 * coding.c: Remove unnecessary static function decls.
4770 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4771 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4772 not a boolean 'int', since callers never look at the return value.
4773 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
4774 * coding.h (decoding_buffer_size, encoding_buffer_size)
4775 (emacs_mule_string_char): Remove unused extern decls.
4776 (struct iso_2022_spec, struct coding_system):

4782 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4784 Fix spare memory change (Bug#12286).
4785 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4786 (valid_lisp_object_p): Likewise.
4788 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4790 * window.c (Fset_window_configuration): Record any window's old
4791 buffer if it's replaced (see Bug#8789). If the new current
4792 buffer doesn't appear in the selected window, go to its old
4795 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4797 Special MEM_TYPE_SPARE to denote reserved memory.
4798 * alloc.c (enum mem_type): New memory type.
4799 (refill_memory_reserve): Use new type for spare memory.
4800 This prevents live_cons_p and live_string_p from incorrect
4801 detection of uninitialized objects from spare memory as live.
4803 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4806 * Makefile.in (.PHONY): versioclean -> versionclean.
4808 Remove unused external symbols.
4809 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
4810 * window.c (Qwindow_valid_p, decode_valid_window):
4811 Now static, not extern.
4812 * data.c (Qinterval): Remove; unused.
4813 (syms_of_data): Do not define 'interval'.
4814 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
4815 * window.h (decode_valid_window):
4818 * character.c, charset.c, chartab.c: Use bool for booleans.
4819 * character.c (lisp_string_width, string_count_byte8)

4828 (char_table_set_range, optimize_sub_char_table)
4829 (map_sub_char_table):
4830 Use bool for boolean.
4831 * character.c (str_to_unibyte): Omit last boolean argument; it was
4832 always 0. All callers changed.
4833 * character.h, charset.h: Adjust to match previous changes.
4834 * character.h (char_printable_p): Remove decl of nonexistent function.
4835 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4836 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4837 are all boolean, so make them single-bit bitfields.
4839 * lisp.h (ASET): Remove attempt to detect side effects.
4840 It was meant to be temporary and it often doesn't work,
4841 because when IDX has side effects the behavior of IDX==IDX
4842 is undefined. See Stefan Monnier in
4843 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4845 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4847 * lisp.h (functionp): New function (extracted from Ffunctionp).
4848 (FUNCTIONP): Use it.
4849 * eval.c (Ffunctionp): Use it.
4851 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4853 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4854 as that's faster and simpler than static storage. Don't bother
4855 with the g_main_context_query overhead if g_main_context_pending
4856 says no events are pending.
4857 (gfds, gfds_size): Remove these static vars.
4858 (xgselect_initialize): Remove; no longer needed.
4859 All uses and decls removed.
4861 * emacs.c (fatal_error_signal_hook): Remove.
4862 All uses removed. This leftover from old code was always 0.
4864 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4865 * casefiddle.c (casify_object, casify_region):
4866 * casetab.c (set_case_table):
4867 * category.c, category.h (word_boundary_p):
4868 * category.h (CHAR_HAS_CATEGORY):
4869 Use bool for booleans, instead of int.
4871 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4873 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4875 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4877 On assertion failure, print backtrace if available.
4878 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4879 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4880 * Makefile.in (LIB_EXECINFO): New macro.
4883 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4884 * bytecode.c (exec_byte_code):
4885 * callint.c (check_mark, Fcall_interactively):
4886 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4887 (getenv_internal, sync_process_alive, call_process_exited):
4888 * lisp.h (USE_SAFE_ALLOCA):
4889 Use bool for booleans, instead of int.
4890 * lisp.h, process.h: Adjust prototypes to match above changes.
4891 * callint.c (Fcall_interactively): Don't assume the mark's
4892 offset fits in 'int'.
4894 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4896 * buffer.c, buffer.h: Use bool for boolean.

4903 (mmap_enlarge, mmap_set_vars):
4904 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4905 Use bool for booleans, instead of int.
4906 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4907 since the 1-or-0 return value is always ignored anyway.
4908 (mmap_initialized_p):
4909 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4910 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4912 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4914 * bidi.c: Use bool for boolean.
4915 This is a bit more readable, and makes the text segment of bidi.o
4916 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4917 Presumably it's faster too.
4918 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

4925 Use bool for booleans, instead of int.
4926 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4927 (bidi_unshelve_cache): Adjust decls to match code.

4941 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4942 compile time tests instead of run time tests on systems that do
4944 (FRAME_MAC_P): Remove leftover from deleted code.
4945 * frame.c (syms_of_frame): Remove leftover from deleted code.
4947 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4949 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4951 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4953 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4954 Otherwise, the compiler complains about (A?B:C) where B is void
4955 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4956 (fontset_add): Return void, for FONTSET_ADD.
4958 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4960 * alloc.c: Use bool for booleans.
4961 (gc_in_progress, abort_on_gc)

4968 (mark_stack, valid_pointer_p, make_pure_string)
4969 (Fgarbage_collect, survives_gc_p, gc_sweep):
4970 Use bool for booleans, instead of int.
4971 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4972 Remove unused local.
4973 * alloc.c (PURE_POINTER_P):
4974 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.

4982 * print.c (Fprin1_to_string):
4983 * xdisp.c (push_message):
4984 Use bool for booleans affected directly or indirectly by

4989 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4990 (set_fontset_default, set_fontset_fallback): Rename from their
4991 upper-case counterparts, and make them functions rather than macros.
4992 This is more consistent with the other recently-introduced setters.
4993 These don't need to be inline, since they're local.
4995 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4997 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4998 the loop (Bug#12247).
5000 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5002 * lisp.h (vcopy): Use memcpy rather than our own loop.
5003 This fixes a performance regression introduced by the recent
5004 addition of vcopy. This means 'vcopy' will need to be modified
5005 for a copying collector, but that's OK. Also, tighten the
5006 checking in the assertion.
5008 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5010 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5011 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5012 non-base glyph for the width of the base character, according to
5013 what x_draw_composite_glyph_string_foreground expects.
5014 Generate WADJUST value according to composition_gstring_width's
5015 expectations, to produce correct width of the composed character.
5016 Reverse the sign of the DU offset produced by ScriptPlace.
5018 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5020 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

5048 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5051 2012-08-20 Glenn Morris <rgm@gnu.org>
5053 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5054 Don't assume that `ln -f' works.
5056 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5058 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5059 and later about non-assignments with no effect. See discussion at
5060 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for

5085 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5086 (set_hash_key_and_value, set_hash_index, set_hash_next)
5087 (set_hash_hash): New functions.
5088 * charset.c, fns.c: Adjust users.

5100 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5102 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5104 Rely on <config.h> + <unistd.h> to declare 'environ',
5105 as gnulib does this if the system doesn't.
5106 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5107 Remove declaration. MS-Windows declares it on stdlib.h which is
5108 included by conf_post.h.
5109 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5110 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

5113 * unexaix.c, unexcoff.c: Include "mem-limits.h".

5117 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5119 2012-08-19 Chong Yidong <cyd@gnu.org>

5134 * nsfont.m (ns_ascii_average_width): Ensure the string
5135 ascii_printable is initialized with a null-terminated character

5141 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5142 Return void, not Lisp_Object. Otherwise, the compiler
5143 complains about (A?B:C) where B is void and C is Lisp_Object
5144 when compiling CHAR_TABLE_SET, due to the recent change to
5145 the API of sub_char_table_set_contents.

5977 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5978 * w32.c (init_environment): Change the default values of many
5979 environment variables in dflt_envvars[] to NULL, to avoid pushing
5980 them into environment when they were not already defined.
5981 Remove the code that deletes site-lisp subdirectories from the default
5982 value of EMACSLOADPATH, as it is no longer needed.
5983 (check_windows_init_file): Now external, not static.
5984 Use Vload_path as is, without adding anything, as this function is now
5985 called when Vload_path is already set up.
5987 * w32.h (check_windows_init_file): Add prototype.
5989 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
5990 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
5991 compatibility with Posix platforms.
5992 (main): Move the call to check_windows_init_file to here from
5994 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
5995 any, in the DEFALT argument into the root of the Emacs build or
5996 installation tree, as appropriate.
5998 * callproc.c (init_callproc_1): Call decode_env_path instead of
5999 doing its equivalent by hand.
6000 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6001 the code that sets Vexec_path run on MS-Windows.
6003 * lread.c (init_lread): Add comments to #ifdef's.
6005 * msdos.c (dos_set_window_size, IT_update_begin)

6015 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
6017 Remove unnecessary casts involving pointers.
6018 These casts are no longer needed now that we assume C89 or later,
6019 since they involve casting to or from void *.
6020 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
6021 (make_pure_float, make_pure_vector):
6022 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6031 (x_get_window_property, x_get_window_property_as_lisp_data):
6032 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6033 Remove unnecessary pointer casts.
6034 * alloc.c (record_xmalloc): New function.
6035 * lisp.h (record_xmalloc): New decl.
6036 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6037 more like a function. This is because the pointer cast is not
6038 needed. All uses changed.
6039 * print.c (print_string, print_error_message): Avoid length recalc.
6041 Improve fix for macroexp crash with debugging (Bug#12118).
6042 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6043 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6044 not supposed to be invoked from the garbage collector.
6045 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6046 (gc_aset): New function, which is like ASET but can be
6047 used in the garbage collector.
6048 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6060 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
6061 (map_w32_filename): Improve commentary. Simplify switch.
6062 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
6063 headers (most versions of MinGW w32api don't).
6064 (get_security_info, create_symbolic_link)
6065 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6067 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6068 in the argument file name.

6071 (sys_rename): Diagnose renaming of a symlink when the user doesn't
6072 have the required privileges.
6073 (get_file_security_desc_by_name): Rename from
6074 get_file_security_desc.
6075 (stat_worker): New function, with most of the guts of 'stat', and
6076 with addition of handling of symlinks and support for 'lstat'.
6077 If possible, get file's attributes and security information by
6078 handle, not by name. Produce S_IFLNK bit for symlinks, when
6079 called from 'lstat'.
6080 (stat, lstat): New functions, call 'stat_worker'.
6081 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6082 symlinks when the underlying filesystem supports them.
6084 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6086 Fix macroexp crash on Windows with debugging (Bug#12118).
6087 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6088 checking subscripts; problem introduced with the recent
6089 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6090 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6091 since it's used in non-static inline functions now.
6093 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6094 Don't assume buffer size fits in 'int'. Remove unused local.

6111 * category.c (CATEGORY_INLINE):
6112 * character.c (CHARACTER_INLINE):
6113 * charset.c (CHARSET_INLINE):
6114 * composite.c (COMPOSITE_INLINE):
6115 * dispnew.c (DISPEXTERN_INLINE):
6116 * sysdep.c (SYSTIME_INLINE):
6117 Define to EXTERN_INLINE, so that the corresponding functions
6118 are compiled into code.
6119 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6120 (INLINE_HEADER_END): New macros.
6121 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6141 hard-coding the path separator.
6143 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6145 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6146 This how ASET and AREF are supposed to work, and makes
6147 it easier to think about future improvements. See
6148 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6149 * charset.h (set_charset_attr): New function.

6402 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
6403 does that unconditionally. Remove file, which is now empty.
6405 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
6408 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
6410 Export to GDB most of lisp.h's remaining object-like macros.

6526 * w32inevt.c: Include w32inevt.h.
6527 (w32_read_console_input): New inline function, calls either
6528 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6529 w32_console_unicode_input.
6530 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6531 (w32_kbd_patch_key, key_event): Use the codepage returned by
6532 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

6564 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6565 enumeration constants, as PURE and HEAP are too general, and clash
6566 with other headers and sources, such as gmalloc.c and the
6567 MS-Windows system headers. All users changed.
6569 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6571 Revert last save_excursion_save and save_excursion_restore changes.
6572 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6582 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
6584 Improve GDB symbol export (Bug#12036).
6585 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6586 arms of an 'if', not using conditional expressions; otherwise GDB
6587 complains about the types in the unevaluated arm when the argument
6588 is an integer literal.
6589 (xgetint): Simplify expression.
6590 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6591 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6592 Zaretskii in <http://bugs.gnu.org/12036#13>.
6593 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6594 needed now that we have gdb_make_enums_visible.
6595 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6596 (enum enum_USE_LSB_TAG):
6597 New enum types, packaging up enums that need to be exported to GDB.

6615 * xdisp.c (syms_of_xdisp): Likewise.
6616 * xfns.c (syms_of_xfns): Likewise.
6618 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6620 Fast save_excursion_save and save_excursion_restore.
6621 * lisp.h (struct Lisp_Excursion): New data type.
6622 (PVEC_EXCURSION): New pseudovector type.
6623 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6624 to deal with it. Adjust comments.

6638 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6639 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6640 emacs.c, as this is a more-suitable home. Had this been done earlier
6641 the fix for 12036 would have avoided some of the problems noted in
6642 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6643 would have been more obvious.
6644 * emacs.c: Do not include <verify.h>; no longer needed.
6645 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6646 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6647 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6648 Remove; now done in lisp.h.

6653 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6654 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6655 not be usable in #if. This simplifies things.
6657 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6659 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6661 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

6664 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6665 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6666 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6667 Adjust to changes in lisp.h and emacs.c, by using
6668 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6669 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6670 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6671 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6672 instead of gdb_valbits.
6673 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6674 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6675 instead of gdb_array_mark_flag.
6676 (xboolvector): Get size from $->size, not $->header.size.
6677 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6678 (xreload, hook-run, hookpost-run): Remove.
6679 * emacs.c: Include <verify.h>.
6680 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6681 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6683 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6684 (gdb_USE_LSB_TAG): New enum constants.
6685 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6686 Also define these as enum constants, so they're visible to GDB.
6687 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6688 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6689 as constants, so they're visible to GDB.
6690 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6691 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6692 Now enum constants, not macros, so they're visible to GDB.
6693 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6694 more convenient now. All uses changed.
6695 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6696 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6698 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6703 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6705 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6706 add argument, tune behavior, and adjust all callers.
6708 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6710 Use typedef for EMACS_INT, EMACS_UINT.
6711 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6712 than macros. This simplifies debugging in the usual case, since
6713 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6714 and it allows expressions involving EMACS_INT casts.
6715 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6717 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6725 that FOCUS-FRAME can be omitted.
6727 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6729 Adjust buffer text indirection counters at the end of Fkill_buffer.
6730 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6731 buffer is definitely dead. This should really fix an issue reported
6732 by Christoph Scholtes again. (Bug#12007).
6733 (init_buffer_once): Initialize indirection counters of
6734 buffer_defaults and buffer_local_symbols (for sanity and safety).
6736 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6738 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6739 and continuation glyphs on tooltip frames, leave them at zero.
6740 Avoids continued lines in tooltips. (Bug#11832)
6742 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6744 Simplify copy_overlay.
6745 * buffer.c (copy_overlay): Simplify. Use build_marker.

6751 or invalid. (Bug#12025)
6753 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
6754 it signals an error when a tooltip frame is being created.

7535 The functional style also makes code easier to read and maintain.
7536 * systime.h: Include <sys/time.h> on all hosts, not just if

7572 (menu_separator_name_p):

7577 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7578 Prefer snprintf to strncpy.
7579 * nsterm.m (ns_term_init):
7580 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7581 * nsterm.m (ns_term_init):
7582 Avoid the need for strncpy, by using build_string or
7583 make_unibyte_string directly. Use dtoastr, not snprintf.
7584 * process.c (Fmake_network_process): Diagnose service names that
7585 are too long, rather than silently truncating them or creating
7586 non-null-terminated names.

7658 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7659 O_RDONLY already includes it).
7661 Stop ns builds setting the EMACSLOADPATH environment variable.
7662 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7663 Now it does not set EMACSLOADPATH, just returns the load-path string.
7664 * nsterm.h: Update accordingly.
7665 * lread.c [HAVE_NS]: Include nsterm.h.
7666 (init_lread) [HAVE_NS]: Use ns_load_path.
7667 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7669 2012-07-09 Glenn Morris <rgm@gnu.org>
7671 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7672 since the included bsd-common.h does so.
7674 Stop ns builds setting the EMACSPATH environment variable.
7675 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7676 (ns_init_paths): Do not set EMACSPATH.
7677 * nsterm.h (ns_exec_path): Add it.
7678 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7681 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7683 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7685 * process.c (wait_reading_process_output): 'waitchannels' was unset
7686 when read_kbd || !NILP (wait_for_cell); fix this.
7688 Add GCC-style 'const' attribute to functions that can use it.
7689 * character.h (char_resolve_modifier_mask):
7690 * keyboard.h (make_ctrl_char):
7691 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7692 (init_character_once, next_almost_prime, init_fns, init_image)
7693 (flush_pending_output, init_sound):
7694 * mem-limits.h (start_of_data):
7695 * menu.h (finish_menu_items):
7696 Add ATTRIBUTE_CONST.
7697 * emacs.c (DEFINE_DUMMY_FUNCTION):
7698 Declare the dummy function with ATTRIBUTE_CONST.
7699 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7700 Add decls with ATTRIBUTE_CONST.
7702 Minor improvements to make_formatted_string.
7703 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7704 where int is good enough, as vsprintf returns an int.
7705 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7707 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7709 Use make_formatted_string to avoid double length calculation.
7710 * lisp.h (make_formatted_string): New prototype.
7711 * alloc.c (make_formatted_string): New function.
7712 * buffer.c (Fgenerate_new_buffer_name): Use it.
7713 * dbusbind.c (syms_of_dbusbind): Likewise.
7714 * editfns.c (Fcurrent_time_zone): Likewise.
7715 * filelock.c (get_boot_time): Likewise.
7716 * frame.c (make_terminal_frame, set_term_frame_name)
7717 (x_report_frame_params): Likewise.
7718 * image.c (gs_load): Likewise.
7719 * minibuf.c (get_minibuffer): Likewise.

7729 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
7730 * nsterm.h (ns_etc_directory): Add it.
7731 * callproc.c [HAVE_NS]: Include nsterm.h.
7732 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
7734 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7736 Move marker debugging code under MARKER_DEBUG.
7737 * marker.c (MARKER_DEBUG): Move marker debugging code under
7738 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7739 for bootstrap with --enable-checking (~3x slowdown reported
7740 by Juanma Barranquero <lekktu@gmail.com>).
7741 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7743 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7745 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7746 See <http://bugs.gnu.org/11825#29>.
7748 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7750 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7751 has no font, use the frame's font. (Bug#11813)
7752 (display_line): Add commentary about displaying truncation glyphs
7754 (produce_special_glyphs): Move here from term.c.
7756 * term.c (produce_special_glyphs): Move to xdisp.c.
7758 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7761 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7763 * xdisp.c (display_line): Avoid warning about implicit declaration
7766 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7768 * lisp.h: Remove empty conditional.
7770 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7772 * lread.c (load_path_check): Now static.
7774 Fix some minor --with-ns problems found by static checking.
7775 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7776 (x_set_font) [!HAVE_X_WINDOWS]:
7777 * image.c (xpm_load_image) [HAVE_NS]:
7778 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7779 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7780 Remove unused local.
7781 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7782 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7783 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7784 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7785 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7786 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7787 Fix pointer signedness problem.
7788 * xfaces.c (FRAME_X_FONT_TABLE):
7789 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7791 2012-07-07 Glenn Morris <rgm@gnu.org>
7793 * lread.c (load_path_check): New function, split from init_lread.
7794 (init_lread): Reorganize. Motivation:
7795 If EMACSLOADPATH is set, check/warn about that rather than the
7796 defaults, which we are not going to use. Hence we can remove
7797 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7798 Don't warn if site-lisp directories are missing.
7799 If not installed, start from a blank load-path, since
7800 PATH_LOADSEARCH refers to the eventual installation directories.
7802 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7804 Support truncation and continuation glyphs on GUI frames, when
7805 fringes are disabled. (Bug#11832)
7806 * xdisp.c (init_iterator): Get dimensions of truncation and
7807 continuation glyphs even if on GUI frames.
7808 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7809 or both, are absent.
7810 (start_display, move_it_in_display_line_to): Handle the case of a
7811 GUI frame without a fringe to display continuation or truncation
7813 (insert_left_trunc_glyphs): Support GUI frames: make sure
7814 truncation glyphs overwrite enough glyphs from the current line to
7815 have sufficient space in pixels.
7816 (display_line): Support truncation and continuation glyphs on GUI
7817 frames. If some spare pixels are left on the line after inserting
7818 the truncation glyphs, fill that space with a stretch glyph of a
7819 suitably computed width.
7821 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7822 produce_glyphs, to support GUI sessions.
7824 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7826 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7828 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7830 Do not require float-time's arg to fit in time_t (Bug#11825).
7831 This works better on hosts where time_t is unsigned, and where
7832 float-time is applied to the (negative) difference between two times.
7833 * editfns.c (decode_time_components): Last arg is now double *,
7834 not int *, and means to store all the result as a double, without
7835 worrying about whether the seconds part fits in time_t.
7836 All callers changed.
7837 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7838 All callers changed.
7839 (Ffloat_time): Do not fail merely because the specified time falls
7840 outside of time_t range.
7842 2012-07-07 Glenn Morris <rgm@gnu.org>
7844 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
7845 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

7848 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7850 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7851 Update dependencies.
7853 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7855 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7857 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7859 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7860 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7861 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7862 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7864 * xfont.c (compare_font_names): Redo to omit the need for casts.
7866 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7868 * xfns.c (Fx_change_window_property): Doc fix.
7869 * w32fns.c (Fx_change_window_property): Doc fix.
7871 * w32fns.c (Fx_window_property): Accept the same arguments as the
7872 X Windows version. Doc fix.
7873 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7875 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7876 Eli Zaretskii <eliz@gnu.org>
7878 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7879 Windows-specific code from nt/config.nt moved here.
7880 Obsolete settings removed.
7882 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7884 * process.c: Avoid unnecessary calls to gettime.
7885 (wait_reading_process_output): Don't get the time of day
7886 when gobbling data immediately and not waiting, as there's no need
7887 for it in that case. This removes a FIXME.
7889 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7891 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7892 is defined (Bug#11768).
7894 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7896 Fix marker debugging code.
7897 * marker.c (byte_char_debug_check): Do not perform the check
7898 if buffer is not multibyte.
7899 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7900 Call byte_char_debug_check with correct arguments.
7902 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7904 Compile marker debugging code only if ENABLE_CHECKING is defined.
7905 * marker.c (byte_char_debug_check, count_markers):
7906 Use only if ENABLE_CHECKING is defined.
7907 (byte_debug_flag): Remove.
7908 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7909 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7911 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7913 Avoid code repetition in marker-related functions.
7914 * marker.c (attach_marker): New function.
7915 (Fset_marker, set_marker_restricted, set_marker_both)
7916 (set_marker_restricted_both): Use it.
7917 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7918 Consistently rename charno to charpos.
7919 (marker_position): Add eassert.
7920 (marker_byte_position): Convert to eassert.

7932 * lisp.h (build_marker): New prototype.
7933 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
7934 * composite.c (autocmp_chars): Likewise.
7935 * editfns.c (buildmark): Remove.
7936 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7937 (save_restriction_save): Use build_marker.
7938 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7939 * window.c (save_window_save): Likewise.
7941 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7943 Do not use Fdelete_overlay in delete_all_overlays
7944 to avoid redundant calls to unchain_overlay.
7945 * buffer.c (drop_overlay): New function.
7946 (delete_all_overlays, Fdelete_overlay): Use it.
7947 * minibuf.c (get_minibuffer): Fix comment.
7949 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7951 Port to OpenBSD 5.1 amd64.
7952 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7953 This is needed for OpenBSD, and should be harmless on all BSD systems.
7954 Also, include <sys/sysctl.h>, as it should be available on all
7955 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7956 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7957 use p_pid member, not kp_proc.pid.
7959 2012-07-06 Glenn Morris <rgm@gnu.org>
7961 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7963 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7965 More xmalloc and related cleanup.
7966 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7967 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

7970 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
7971 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
7972 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
7973 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7974 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7976 Omit needless casts involving void * pointers and allocation.
7977 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7978 as the former is more robust if P's type is changed.
7979 Prefer xzalloc to xmalloc + memset 0.
7980 Simplify malloc-or-realloc to realloc.
7981 Don't worry about xmalloc returning a null pointer.
7982 Prefer xstrdup to xmalloc + strcpy.
7983 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7985 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7986 alloca of a constant.
7988 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7990 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7991 hscroll is larger than the line width. Fixes long and futile
7992 looping inside extend_face_to_end_of_line (on a TTY) producing
7993 glyphs that are not needed and thrown away.
7995 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7997 * marker.c (set_marker_restricted_both): Simplify by using

8011 followed by gtk_box_set_homogeneous (Bug#11768).
8012 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8013 (update_theme_scrollbar_width, xg_create_scroll_bar):
8014 Use gtk_scrollbar_new (Bug#11768).
8015 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8016 (is_box_type): New function (Bug#11768).
8017 (xg_tool_item_stale_p): Call is_box_type.
8018 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8019 with default display (Bug#11768).
8021 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8023 * xdisp.c (window_hscroll_limited): New function.
8024 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8025 coordinates when window's hscroll is set to insanely large
8028 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8030 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8031 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8033 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8036 * lisp.h (xzalloc): New prototype. Omit needless casts.
8037 * alloc.c (xzalloc): New function. Omit needless casts.

8092 Problem reported by Troels Nielsen in
8093 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8095 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8097 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8098 This should be fixed in a better way; see Eli Zaretskii in
8099 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8100 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8102 * fileio.c (time_error_value): Rename from special_mtime.
8103 The old name's problems were noted by Eli Zaretskii in
8104 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8106 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8107 This variable's comment says Emacs needs at least one GDB-visible
8108 symbol of type enum pvec_type, to work around GDB problems.
8109 The symbol's value doesn't matter.
8111 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8112 that causes compilation to fail on pre-C99 compilers.
8114 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8116 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8117 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8119 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

8122 headers for buffer_defaults and buffer_local_symbols.
8123 Reported by Juanma Barranquero <lekktu@gmail.com>.
8125 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8127 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8128 * lisp.h (enum pvec_type): Use fewer bits.
8129 (PSEUDOVECTOR_SIZE_BITS): New constant.
8130 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8131 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8132 change in pvec_type.
8133 (PSEUDOVECTOR_TYPEP): New macro.
8134 (TYPED_PSEUDOVECTORP): Use it.
8135 * fns.c (internal_equal): Adapt code to extract pvectype.

8139 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8140 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8141 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8142 abusing vector->header.next.nbytes.
8143 (live_vector_p): Use PVEC_TYPE.
8144 (mark_object): Adapt code to extract pvectype. Use switch.
8146 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8148 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8149 Tighten new eassert a bit.
8151 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8153 Fix compilation with --enable-gcc-warnings and -O1
8155 * doprnt.c (doprnt): Change type of tem to int, initialize
8156 to avoid compiler warning. Add eassert.
8157 * search.c (simple_search): Initialize match_byte to avoid
8158 compiler warning. Add eassert.
8160 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8162 Avoid weird behavior with large horizontal scrolls.
8163 Without this change, for example, large hscroll values would
8164 mess up Emacs's display on Fedora 15 x86, presumably due to
8165 overflows in int calculations in the display code.
8166 Also, if buffers had long lines, Emacs would freeze.
8167 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8168 (set_window_hscroll): New function, containing the old guts of
8169 Fset_window_hscroll. Return the clipped value.
8170 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8171 This avoids the need to check against PTRDIFF_MAX.
8173 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8175 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8177 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8179 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8181 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8182 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8183 since GCC 4.4.6 issues a bogus warning for them.
8185 Fix bugs in file timestamp newness comparisons.
8186 * fileio.c (Ffile_newer_than_file_p):
8187 * lread.c (Fload): Use full timestamp resolution of files,
8188 not just the 1-second resolution, so that files that are only
8189 slightly newer still count as newer.
8190 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8191 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8193 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8195 * fileio.c: Improve handling of file time marker. (Bug#11852)
8196 (special_mtime): New function.
8197 (Finsert_file_contents, Fverify_visited_file_modtime):
8198 Use it to set special mtime values consistently.
8200 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8202 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8203 marker for non-existing file. (Bug#11852)
8205 2012-07-03 Glenn Morris <rgm@gnu.org>
8207 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8208 and did not make it into globals.h).
8210 2012-07-03 Tom Tromey <tromey@redhat.com>
8212 * window.c (Fset_window_margins, Fset_window_fringes)

8238 * fontset.h: Remove EXFUN.

8248 2012-07-03 Glenn Morris <rgm@gnu.org>
8250 * lisp.h (Frandom): Make it visible to C.
8251 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8252 buffer for invisible buffers. (Bug#1229)

8256 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8257 values which aren't power of 2.
8258 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8259 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8262 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8264 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8266 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8268 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8270 * alloc.c (allocate_vector_block): Remove redundant
8271 calls to mallopt if DOUG_LEA_MALLOC is defined.
8272 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8273 avoid calls to mallopt if zero_vector is returned.
8275 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8277 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8278 is enabled, avoid dereferencing NULL current_sblock if
8281 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8283 Cleanup basic buffer management.
8284 * buffer.h (struct buffer): Change layout to use generic vector
8285 marking code. Fix some comments. Change type of 'clip_changed'
8286 to bitfield. Remove unused #ifndef old.
8287 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8288 (GET_OVERLAYS_AT): Fix indentation.
8289 (for_each_per_buffer_object_at): New macro.
8290 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8291 (Fbuffer_local_variables): Use it.
8292 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8293 * alloc.c (allocate_buffer): Adjust to match new layout of
8294 struct buffer. Fix comment.
8295 (mark_overlay): New function.
8296 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8297 Lisp area of struct buffer.
8298 (mark_object): Use it. Adjust marking of misc objects
8299 and related comments.
8301 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8303 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8304 wrapper that is not needed because the wrapped code is a no-op (zero
8305 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8306 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8308 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8310 * alloc.c (mark_buffer): Simplify. Remove prototype.
8311 (mark_object): Add comment. Reorganize marking of vector-like
8312 objects. Use CHECK_LIVE for all vector-like objects except buffers
8313 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8314 Avoid redundant calls to mark_vectorlike for bool vectors.
8316 2012-06-30 Glenn Morris <rgm@gnu.org>
8318 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8320 * epaths.in (PATH_SITELOADSEARCH): New.
8321 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8322 This is rather than relying on --enable-locallisppath elements
8323 having "site-lisp" in their names. (Bug#10208#25, 11658)
8325 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8327 * w32proc.c (sys_select): Accept and ignore one more argument.
8329 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8331 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8332 (pselect) [!MS_DOS]: Redirect to sys_select.
8334 * sysdep.c: Don't include dos.h and dosfns.h.
8336 * process.c (sys_select):
8337 * msdos.c (sys_select): Accept one more argument and ignore it.
8339 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8340 adapt data types and code to that.
8343 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8344 which clashes with the gnulib function of the same name.
8346 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8348 * font.c (font_style_to_value, font_style_symbolic)
8349 (font_prop_validate_style): Add type checks for values in
8352 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8354 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8357 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8359 * xdisp.c (try_window_id): Undo last change.
8361 * w32.c (getwd): Adjust commentary about startup_dir.
8362 (init_environment): Always call sys_access, even in non-MSVC
8363 builds. Don't chdir to the directory of the Emacs executable.
8364 This undoes code from 1997 which was justified by the need to
8365 "avoid conflicts when removing and renaming directories". But its
8366 downside was that every relative file name was being interpreted
8367 relative to the directory of the Emacs executable, which can never
8368 be TRT. In particular, it broke sys_access when called with
8369 relative file names.
8370 (sys_access): Map GetLastError to errno.
8372 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8374 * window.h (struct window): Change type of 'fringes_outside_margins'

8378 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8381 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

8384 Add QUIT to make the loop interruptible.
8386 2012-06-29 Glenn Morris <rgm@gnu.org>
8388 * charset.c (init_charset): Make lack of etc/charsets fatal.
8390 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8392 * editfns.c (region_limit): Fix type mismatch.
8394 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8396 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8397 undefined. Convert from xassert to eassert.
8398 * nsmenu.m: Convert from xassert to eassert.
8399 * nsterm.m: Likewise.
8401 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8403 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8405 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8407 Avoid integer overflow on scroll-left and scroll-right.
8408 * window.c (HSCROLL_MAX): New macro.
8409 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8410 overflow when requested scroll falls outside ptrdiff_t range.
8412 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8414 * window.h (struct window): Change type of 'hscroll',
8415 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8416 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8417 Adjust users accordingly.
8418 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8419 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8420 from EMACS_INT to ptrdiff_t.
8421 (make_window): Omit redundant initialization.
8423 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8427 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8429 * window.h (struct window): Change type of 'use_time' and
8430 'sequence_number' from Lisp_Object to int.

8496 * alloc.c (allocate_string): Omit intervals initialization.
8497 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8498 as in make_pure_string and make_pure_c_string.

8554 * alloc.c: Remove build_string.
8555 * lisp.h: Define build_string as static inline. This provides
8556 a better opportunity to optimize away calls to strlen when the
8557 function is called with compile-time constant argument.
8558 * image.c (imagemagick_error): Convert to build_string.
8559 * w32proc.c (sys_spawnve): Likewise.
8560 * xterm.c (x_term_init): Likewise.
8562 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8564 Use sprintf return value instead of invoking strlen on result.
8565 In the old days this wasn't portable, since some sprintf
8566 implementations returned char *. But they died out years ago and
8567 Emacs already assumes sprintf returns int.
8568 Similarly for float_to_string.
8569 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8570 * ccl.c (ccl_driver):
8571 * character.c (string_escape_byte8):

8576 * xfns.c (syms_of_xfns):
8577 Use sprintf or float_to_string result to avoid need to call strlen.
8578 * data.c (Fnumber_to_string):
8579 Use make_unibyte_string, since the string must be ASCII.
8580 * lisp.h, print.c (float_to_string): Now returns int length.
8581 * term.c (produce_glyphless_glyph):
8582 Use sprintf result rather than recomputing it.
8584 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8585 * Makefile.in (ALL_CFLAGS):

8753 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8755 Support higher-resolution time stamps (Bug#9000).
8756 The time stamps are only nanosecond-resolution at the C level,
8757 since that's the best that any real-world system supports now.
8758 But they are picosecond-resolution at the Lisp level, as that's
8759 easy, and leaves room for future OS improvements.
8761 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8764 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8765 Don't get current time unless it's needed.
8767 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8768 now provides it if it's absent.
8769 (start_atimer): Port to higher-res time stamps.
8770 Check for time stamp overflow. Don't get current time more
8771 often than is needed.
8773 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8774 Include systime.h, not time.h.
8775 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8777 * dired.c: Include stat-time.h.
8778 (Ffile-attributes): File times now have higher resolution.
8780 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8781 (struct image): Timestamp now has higher resolution.
8783 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8784 has at least microseconds now. All uses removed.
8785 (update_frame, update_single_window, update_window, update_frame_1)
8786 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8787 (duration_to_sec_usec): Remove; no longer needed.
8789 * editfns.c (time_overflow): Now extern.
8790 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8791 (float-time, Fformat_time_string, Fcurrent_time_string)
8792 (Fcurrent_time_zone): Accept and generate higher-resolution
8794 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
8795 (decode_time_components, lisp_seconds_argument): New functions.
8796 (make_time): Now static.
8797 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8798 Report an error if the time is invalid, rather than having the caller
8801 * fileio.c: Include <stat-time.h>
8802 (Fcopy_file): Copy higher-resolution time stamps.
8803 Prefer to set the time stamp via a file descriptor if that works.
8804 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8805 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8806 (Fvisited_file_modtime, Fset_visited_file_modtime):
8807 Support higher-resolution time stamps.
8809 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8811 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8813 * image.c (prepare_image_for_display, clear_image_cache)
8814 (lookup_image): Port to higer-resolution time stamps.
8816 * keyboard.c (start_polling, bind_polling_period):
8817 Check for time stamp overflow.
8818 (read_char, kbd_buffer_get_event, timer_start_idle)
8819 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8820 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8821 Port to higher-resolution time stamps. Do not assume time_t is signed.
8822 (decode_timer): New function. Timers are now vectors of length 9,
8823 not 8, to accommodate the picosecond component.
8824 (timer_check_2): Use it.
8826 * nsterm.m (select_timeout, timeval_subtract): Remove.
8827 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8828 as they're a bit more accurate and handle overflow better.
8829 (ns_select): Change prototype to be compatible with pselect.
8830 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8831 * nsterm.h (ns_select): Adjust prototype.
8833 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8834 us-resolution time stamps.
8835 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8837 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8839 * lisp.h (time_overflow): New decl.
8840 (wait_reading_process_output): First arg is now intmax_t, not int,
8841 to accommodate larger waits.
8843 * process.h (struct Lisp_Process.read_output_delay):
8844 Now counts nanoseconds, not microseconds.
8845 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8847 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8848 (wait_reading_process_output):
8849 Port to ns-resolution time stamps.
8850 (Faccept_process_output, wait_reading_process_output):
8851 Check for time stamp overflow. Do not assume time_t is signed.
8852 (select_wrapper): Remove; we now use pselect.
8853 (Fprocess_attributes): Now generates ns-resolution time stamps.
8855 * sysdep.c: Include utimens.h. Don't include utime.h
8856 or worry about struct utimbuf; gnulib does that for us now.
8857 (gettimeofday): Remove; gnulib provides a substitute.
8858 (make_timeval): New function.
8859 (set_file_times): Now sets ns-resolution time stamps.
8860 New arg FD; all uses changed.
8861 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8862 (system_process_attributes):
8863 Now returns ns-resolution time stamp. All uses changed.
8864 Check for time stamp overflow.
8866 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8867 provides a substitute now.
8869 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8870 since it guarantees struct timespec.
8871 (EMACS_TIME): Now struct timespec, so that we can support
8872 ns-resolution time stamps.
8873 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8874 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8875 (EMACS_USECS): Remove.
8876 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8877 so multiply the arg by 1000 before storing it.
8878 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8880 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8881 Port to ns-resolution time stamps.
8882 (EMACS_TIME_NEG_P): Remove; replaced by....
8883 (EMACS_TIME_SIGN): New macro.
8884 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8885 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8886 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8887 (make_timeval, make_lisp_time, decode_time_components): New decls.
8888 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8889 that it mishandled time_t overflow. You can't compare by subtracting!
8890 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8891 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8893 * term.c: Include <sys/time.h>.
8894 (timeval_to_Time): New function, for proper overflow wraparound.

8899 (Fprimitive_undo): Use them when restoring time stamps.
8901 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8902 (w32_get_internal_run_time):
8903 Port to higher-resolution Emacs time stamps.
8904 (ltime): Now accepts single 64-bit integer, as that's more convenient
8907 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8909 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8910 for compatibility with pselect. Support ns-resolution time stamps.
8912 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8914 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8915 Check for time stamp overflow, and support ns-resolution time stamps.
8917 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8918 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8919 (timeval_subtract): Remove; no longer needed.
8920 (XTflash, XTring_bell, x_wait_for_event):
8921 Port to ns-resolution time stamps. Don't assume time_t is signed.
8923 2012-06-22 Chong Yidong <cyd@gnu.org>

8927 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8929 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8930 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8931 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8932 staticidx goes up to 1597 out of 1600 = 0x640.)
8934 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8936 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8937 Otherwise, the umask might be mistakenly 0 while handling input signals.

8958 (unwind_format_mode_line): Restore them.
8959 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8961 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8962 since tty frames can be explicitly named.
8963 (prepare_menu_bars): Likewise.
8965 * term.c (Ftty_top_frame): New function.
8967 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8970 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8971 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8972 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8973 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8974 (METER_1, METER_2): Simplify.
8976 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

8980 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8982 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8983 gets killed during executing of this function (Bug#11665).
8984 Try to always return Qt when the buffer has been actually killed.
8985 (Vkill_buffer_query_functions): In doc-string say that functions
8986 run by this hook should not change the current buffer.
8988 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8990 Fix recently-introduced process.c problems found by static checking.

9008 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9010 * lisp.h (eassert): Assume C89 or later.
9011 This removes the need for CHECK.
9012 (CHECK): Remove. Its comments about always evaluating its
9013 argument were confusing, as 'eassert' typically does not evaluate
9016 * coding.c (produce_chars): Use ptrdiff_t, not int.
9018 * xterm.c (x_draw_underwave): Check for integer overflow.
9019 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9203 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
9204 code works fine either way, and efficiency is not a concern here,
9205 as the union type is for debugging, not for production.
9206 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9207 Use an inline function on all platforms when using the union type,
9208 since this is simpler and 'static inline' can be used portably
9210 (LISP_INITIALLY_ZERO): New macro.
9211 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

9319 * alloc.c (allocate_vectorlike): Fix last change.

9323 Block-based vector allocation of small vectors.
9324 * lisp.h (struct vectorlike_header): New field `nbytes',
9325 adjust comment accordingly.
9326 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

9350 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9352 * doprnt.c (doprnt): Truncate multibyte char correctly.
9353 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9354 would mishandle a string argument "Xc" if X was a multibyte
9355 character of length 2: it would truncate after X's first byte
9356 rather than including all of X.
9358 2012-06-06 Chong Yidong <cyd@gnu.org>

9409 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9410 Convert pctcpu and pctmem to Lisp float properly.
9411 Let the compiler fold better, as 100.0/0x8000 is exact.

9415 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

9425 bitfields where appropriate, remove unused fields.
9426 * window.h (struct window): Remove unused 'last_mark_x' and
9427 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

9429 Change type of 'force_start', 'optional_new_start',
9430 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9431 fields from Lisp_Object to bitfield. Adjust users accordingly.

9437 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:

9439 and 'double' in a couple of places.
9441 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9443 * xdisp.c (handle_stop): Detect whether we have overlay strings
9444 loaded by testing it->current.overlay_string_index to be
9445 non-negative, instead of checking whether n_overlay_strings is
9446 positive. (Bug#11587)
9448 2012-05-31 Chong Yidong <cyd@gnu.org>
9450 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

9456 * search.c (search_buffer): Remove calls to
9457 r_alloc_inhibit_buffer_relocation, as it is now called by
9458 maybe_unify_char, which was the cause of relocation of buffer text
9461 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9463 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9464 for the duration of call to load_charset, to avoid problems with
9465 callers of maybe_unify_char that access buffer text through C
9468 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9469 decrement the inhibition flag, instead of just setting or
9472 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9474 Remove obsolete '#define static' cruft.
9475 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9476 This #undef was "temporary" in 2000; it is no longer needed
9477 now that '#define static' has gone away.
9478 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9479 (gray_bitmap_bits): Remove; no longer needed.
9480 All uses replaced with definiens.

9492 (safe_bcopy): Remove decl; no longer has that name.
9493 (main): Coalesce #if into single bit of code, for simplicity.

9524 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9525 Bug#9642, but explicitly check that the buffer the overlay would
9526 be moved to is live and rearrange lines to make sure that errors
9527 will not put the overlay in an inconsistent state.
9528 (Fdelete_overlay): Cosmetics.
9530 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9532 * w32term.c (my_bring_window_to_top): New function.
9533 (x_raise_frame): Use handle returned by DeferWindowPos, which

9564 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9566 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9567 Only r_alloc_inhibit_buffer_relocation needed to be added;
9568 the others were already declared.
9570 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9571 before checking whether it's out of range. Put the check inside
9573 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9575 2012-05-27 Ken Brown <kbrown@cornell.edu>
9577 * callproc.c (Fcall_process): Restore a line that was accidentally
9578 commented out in the 2011-02-13 change (bug#11547).
9580 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9582 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9583 defined on ralloc.c.
9585 * buffer.c [REL_ALLOC]: Remove prototypes of
9586 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9587 they are now on lisp.h.
9589 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9591 * search.c (search_buffer): Use it to inhibit relocation of buffer
9592 text while re_search_2 is doing its job, because re_search_2 is
9593 passed C pointers to buffer text. (Bug#11519)
9595 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9598 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9599 state after an additional call to move_it_in_display_line_to, keep
9600 the values of it->max_ascent and it->max_descent found for the
9602 (pos_visible_p): Revert the comparison against bottom_y to what it
9603 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9606 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9608 Fix coding-related core dumps with gcc -ftrapv.
9609 The code was computing A - B, where A and B are pointers, and B is
9610 random garbage. This can lead to core dumps on platforms that
9611 have special pointer registers, and it also leads to core dumps on
9612 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9613 A - B only when B is initialized properly.
9614 * coding.c (coding_set_source, coding_set_destination): Return void.
9615 (coding_change_source, coding_change_destinations): New functions,
9616 with the old behaviors of coding_set_source and coding_set_destination.

9627 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9629 * w32console.c: Include window.h.
9630 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9632 (initialize_w32_display): Initialize mouse-highlight data.
9634 * w32inevt.c: Include termchar.h and window.h.
9635 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9636 moves, call note_mouse_highlight. If help_echo changed, call
9637 gen_help_event to produce help-echo message in the echo area.
9638 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9641 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9643 * lread.c (read1): Simplify slightly to avoid an overflow warning
9644 with GCC 4.7.0 on x86-64.
9646 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9648 * bidi.c (bidi_mirror_char): Revert last change: an int is
9649 definitely wide enough here.
9651 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9653 Fix integer width and related bugs (Bug#9874).

9664 (allocate_pseudovector):
9665 Use int, not EMACS_INT, where int is wide enough.
9666 (inhibit_garbage_collection, Fgarbage_collect):
9667 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9685 (Foverlay_recenter, last_overlay_modification_hooks_used)
9686 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9687 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9688 (validate_region): Omit unnecessary test for b <= e,
9689 since that's guaranteed by the previous test.
9690 (adjust_overlays_for_delete): Avoid pos + length overflow.
9691 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9692 (report_overlay_modification):
9693 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9694 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

9696 after the EMACS_INT -> ptrdiff_t change.

9698 * buffer.h: Adjust decls to match defn changes elsewhere.

9703 not int, to avoid needless 32-bit limit on 64-bit hosts.
9704 (exec_byte_code): Use tighter memory-full test, one that checks
9705 for alloca overflow. Don't compute the address of the object just
9706 before an array, as that's not portable. Use EMACS_INT, not
9707 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9708 * callint.c (Fcall_interactively):
9709 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9721 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9722 (casify_object): Avoid integer overflow when overallocating buffer.
9723 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9724 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9725 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9726 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9727 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9728 integers are now checked earlier. All uses replaced with XINT.
9730 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9731 For CCL_MapSingle, check that content and value are in int range.
9732 (ccl_driver, Fregister_code_conversion_map):
9733 Check that Vcode_version_map_vector is a vector.
9734 (resolve_symbol_ccl_program): Check that vector header is in range.
9735 Always copy the vector, so that we can check its contents reliably
9736 now rather than having to recheck each instruction as it's being
9737 executed. Check that vector words fit in 'int'.
9738 (ccl_get_compiled_code, Fregister_ccl_program)
9739 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9740 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9741 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9742 contents are in range.
9743 (Fccl_execute_on_string): Check that status is in range.
9744 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9745 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9746 Accept and return EMACS_INT, not int, because callers can pass values

9753 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9754 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9755 avoid mishandling large integers.
9756 * character.h: Adjust decls to match defn changes elsewhere.

9765 (Fdefine_charset_internal): Check ranges here, more carefully.
9766 Don't rely on undefined behavior with signed left shift overflow.
9767 Don't assume unsigned int fits into fixnum, or that fixnum fits
9768 into unsigned int. Don't require max_code to be a valid fixnum;
9769 that's not true for gb10830 4-byte on a 32-bit host. Allow
9770 invalid_code to be a cons, for the same reason. Require code_offset
9771 to be a character. Avoid int overflow if max_char is close
9773 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9774 this is intended anyway and avoids some undefined behavior.
9775 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9776 INDEX_TO_CODE_POINT, as that's what it expects.
9777 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9778 * charset.h (DECODE_CHAR): Return int, not unsigned;
9779 this is what was intended anyway, and it avoids undefined behavior.
9780 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9781 integer-overflow issues.
9782 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9783 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9784 where the argument is EMACS_INT, and this behavior is not intended.
9785 * chartab.c (Fmake_char_table, Fset_char_table_range)
9786 (uniprop_get_decoder, uniprop_get_encoder):
9787 Don't assume fixnum fits in int.
9788 * cmds.c (move_point): New function, that does the gist of
9789 Fforward_char and Fbackward_char, but does so while checking
9790 for integer overflow more accurately.
9791 (Fforward_char, Fbackward_char): Use it.
9792 (Fforward_line, Fend_of_line, internal_self_insert)
9793 (internal_self_insert):
9794 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10585 (report_error, report_error_1, make_hdr, copy_sym)
10586 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10587 Make arguments const char *, not char *, to avoid violations of C

10590 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10592 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10593 already have overlays loaded.
10594 (handle_single_display_spec): Before returning without displaying
10595 fringe bitmap, synchronize the bidi iterator with the main display
10596 iterator, by calling iterate_out_of_display_property.
10597 (iterate_out_of_display_property): Detect buffer iteration by
10598 testing that it->string is a Lisp string.
10599 (get_next_display_element): When the current object is exhausted,
10600 and there's something on it->stack, call set_iterator_to_next to
10601 proceed with what's on the stack, instead of returning zero.
10602 (set_iterator_to_next): If called at the end of a Lisp string,
10603 proceed to consider_string_end without incrementing string
10604 position. Don't increment display vector index past the end of
10605 the display vector. (Bug#11417)
10606 (pos_visible_p): Don't report a position visible when move_it_to
10607 stopped at the last line of window, which happens to be scanned
10608 backwards by the bidi iteration. (Bug#11464)
10610 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10612 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10613 and right-margin display specs even if the spec is invalid or we
10614 are on a TTY, and thus unable to display on the fringes.
10615 That's because the text with the property will not be displayed anyway,
10616 so we need to signal to the caller that this is a "replacing"
10617 display spec. This fixes display when the spec is invalid or we
10620 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10622 * unexaix.c (make_hdr): Fix typo in prototype.

10638 2012-05-12 Glenn Morris <rgm@gnu.org>
10640 * Makefile.in (MKDIR_P): New, set by configure.

10655 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10657 * xgselect.c (xg_select): Put maxfds+1 into a var.
10658 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10660 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10662 2012-05-10 Dave Abrahams <dave@boostpro.com>
10664 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10665 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10667 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10669 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10670 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10671 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10672 Initialize xd_registered_buses.
10674 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10676 Untag more efficiently if USE_LSB_TAG.
10677 This is based on a proposal by YAMAMOTO Mitsuharu in
10678 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10679 For an admittedly artificial (nth 8000 longlist) benchmark on
10680 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10681 Emacs's overall text size by 1%.
10682 * lisp.h (XUNTAG): New macro.
10683 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10684 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10685 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10686 * eval.c (Fautoload):
10687 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10688 * frame.h (XFRAME): Use XUNTAG.
10690 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10691 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10692 Remove unportable assumptions about print widths of types like
10694 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10695 intptr_t when converting between pointer and integer, to avoid GCC
10696 warnings about wrong width.
10698 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10700 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10701 stack for each reader_thread, instead of defaulting to 8MB
10702 determined by the linker. This avoids failures in creating
10703 subprocesses on Windows 7, see the discussion in this thread:
10704 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10706 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10708 Fix up display of the *Minibuf-0* buffer in the mini window.
10709 * keyboard.c (read_char): Don't clear the echo area if there's no
10711 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10712 contents of *Minibuf-0*) if there's no message displayed in its stead.
10714 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10716 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10719 2012-05-06 Chong Yidong <cyd@gnu.org>
10721 * lisp.mk (lisp): Update.
10723 2012-05-05 Jim Meyering <meyering@redhat.com>
10725 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10727 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10729 * data.c (PUT_ERROR): New macro.
10730 (syms_of_data): Use it. Add new error type `user-error'.
10731 * undo.c (user_error): New function.
10732 (Fprimitive_undo): Use it.
10733 * print.c (print_error_message): Adjust print style for `user-error'.
10734 * keyboard.c (user_error): New function.
10735 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10737 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10739 Do not limit current-time-string to years 1000..9999.
10740 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10741 (Fcurrent_time_string): Support any year that is supported by the
10742 underlying localtime representation. Don't use asctime, as it
10743 has undefined behavior for years outside the range -999..9999.
10745 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10747 Fix race conditions involving setenv, gmtime, localtime, asctime.
10748 Without this fix, interrupts could mess up code that uses these
10749 nonreentrant functions, since setting TZ invalidates existing
10750 tm_zone or tzname values, and since most of these functions return
10751 pointers to static storage.
10752 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10753 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10754 Grow the critical sections to include not just invoking
10755 localtime/gmtime, but also accessing these functions' results
10756 including their tm_zone values if any, and any related TZ setting.
10757 (format_time_string): Last arg is now struct tm *, not struct tm **,
10758 so that the struct tm is saved in the critical section.
10759 All callers changed. Simplify allocation of initial buffer, partly
10760 motivated by the fact that memory allocation needs to be outside
10761 the critical section.
10763 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10765 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10766 with RESET_INTERVAL.
10768 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10769 Remove duplicated buffer name initialization.
10771 2012-05-02 Jim Meyering <jim@meyering.net>
10773 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10775 * xfns.c (x_window): Use xstrdup (Bug#11375).
10777 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10779 * xdisp.c (pos_visible_p): If already at a newline from the
10780 display string before the 'while' loop, don't walk back the glyphs
10781 from it3.glyph_row. Solves assertion violation when the display
10782 string begins with a newline (egg.el). (Bug#11367)
10784 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10786 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10789 2012-05-01 Glenn Morris <rgm@gnu.org>
10791 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10792 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10793 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10794 All were removed before 23.1.
10796 * dispnew.c: Remove HAVE_LIBNCURSES test;
10797 it is always true on relevant platforms.
10799 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10800 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10802 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10804 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10806 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10807 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10810 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10812 Do not avoid creating empty evaporating overlays (Bug#9642).
10813 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10814 That is, do not delete an evaporating overlay if it becomes
10815 empty after its bounds are adjusted to fit within its buffer.
10816 This fix caused other problems, and I'm reverting it until we get
10817 to the bottom of them.
10819 2012-04-27 Chong Yidong <cyd@gnu.org>
10821 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10823 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10825 * xdisp.c (pos_visible_p): If the window start position is beyond
10826 ZV, start the display from buffer beginning. Prevents assertion
10827 violation in init_iterator when the minibuffer window is scrolled
10828 via the scroll bar.
10830 * window.c (window_scroll_pixel_based): Likewise.
10832 2012-04-27 Chong Yidong <cyd@gnu.org>
10834 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10836 2012-04-27 Glenn Morris <rgm@gnu.org>
10838 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10839 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10841 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10843 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10844 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10846 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10848 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10849 display element, check also the underlying string or buffer
10850 character. (Bug#11341)
10852 * w32menu.c: Include w32heap.h.
10853 (add_menu_item): If the call to AppendMenuW (via
10854 unicode_append_menu) fails, disable Unicode menus only if we are
10855 running on Windows 9X/Me.
10857 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10859 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10860 (xgetint): Add missing shift for LSB tags.
10862 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10864 * keyboard.c (read_char): Don't wipe echo area for select window
10865 events: These might get delayed via `mouse-autoselect-window'
10868 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10870 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10871 manipulation of :loaded-from data.
10873 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10875 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10876 now a cons (bug#11311).
10878 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10880 Do not create empty overlays with the evaporate property (Bug#9642).
10881 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10882 if it becomes empty after its bounds are adjusted to fit within
10883 its buffer. Without this fix, in a nonempty buffer (let ((o
10884 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10885 yields an empty overlay that has the evaporate property, which is
10886 not supposed to happen.
10888 Fix minor GTK3 problems found by static checking.
10889 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10890 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10891 (struct _EmacsFixedClass, emacs_fixed_get_type):
10892 Move decls here from emacsgtkfixed.h, since they needn't be public.

10894 (emacs_fixed_class_init): Omit unused local.
10895 (emacs_fixed_child_type): Remove; unused.

10897 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10898 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10899 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10900 (EMACS_FIXED_GET_CLASS): Remove; unused.
10901 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10903 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10904 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10906 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10908 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10909 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10910 (__malloc_size_t, __malloc_ptrdiff_t):
10911 Remove. All uses removed, replaced by the definiens if needed,
10912 since we can assume C89 or better now.
10913 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
10914 (protect_malloc_state, align, get_contiguous_space)
10915 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

10920 (special_realloc, _realloc_internal_nolock, _realloc_internal)
10921 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10922 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10923 Define using prototypes, not old style.
10924 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10925 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
10926 (align): Don't assume that signed integer overflow wraps around.
10927 Omit unused local var.
10928 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

10930 Omit no-longer-needed casts.
10931 (valloc): Use getpagesize, not __getpagesize.
10932 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10933 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10935 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10937 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
10939 Move functions from C to Lisp. Make non-blocking method calls
10940 the default. Implement further D-Bus standard interfaces.

10970 (Fdbus_method_return_internal, Fdbus_method_error_internal)
10971 (Fdbus_send_signal, Fdbus_register_service)
10972 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

10985 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
10986 Do not assume ptrdiff_t is the same width as 'int'.
10988 * alloc.c: Handle unusual debugging option combinations.
10989 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10990 since the two debugging options are incompatible.
10991 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
10993 (mem_init, mem_insert, mem_insert_fixup):
10994 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

11004 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11005 Use Emacs indenting style more consistently. Avoid some casts.
11006 Use 'double' consistently rather than mixing 'float' and 'double'.
11008 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11010 * sysdep.c (list_system_processes, system_process_attributes):

11045 row, return zero immediately.
11046 (try_cursor_movement): If inside continuation line, don't back up
11047 farther than the first row after the header line, if any.
11048 Don't consider the header-line row as "partially visible", even if
11049 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11051 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

11087 New extern decls, to avoid calling undeclared functions.
11088 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11089 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11090 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11091 (NEED_MEM_INSERT): New macro.
11092 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11093 Remove one incorrect comment and fix another.
11095 Fix minor ralloc.c problems found by static checking.

11107 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11108 Remove decls. This fixes an "It stinks!".
11110 * alloc.c (which_symbols): Fix alignment issue / type clash.
11112 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11114 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11115 (struct Lisp_Misc_Any): Likewise.
11116 (struct Lisp_Free): Likewise.
11117 * alloc.c (union aligned_Lisp_Symbol): Define.

11127 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11128 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11129 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11130 * s/netbsd.h, s/sol2-6.h:
11131 Remove definition of GC_MARK_STACK, since the default now works.
11132 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11133 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11134 no longer the default.
11135 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11137 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11139 * lread.c (lisp_file_lexically_bound_p):
11140 Fix hang at ";-*-\n" (bug#11238).
11142 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11144 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

11156 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11158 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11160 2012-04-11 Daniel Colascione <dancol@dancol.org>
11162 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11163 against is gone. It's better to use vfork now so that when Cygwin
11164 gains a new, working vfork, we use it automatically (bug#10398).
11166 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11184 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11186 * w32.c (w32_delayed_load): Record the full path of the library
11187 being loaded (bug#10424).
11189 2012-04-09 Glenn Morris <rgm@gnu.org>
11191 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11192 not just in the obarray, before snarfing them. (Bug#11036)
11194 * Makefile.in ($(leimdir)/leim-list.el):
11195 Pass EMACS rather than BUILT_EMACS.
11197 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11199 * process.c (make_process):
11200 * process.h: Add integer `gnutls_handshakes_tried' member to

11209 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11210 attempts per process (connection).
11212 2012-04-09 Chong Yidong <cyd@gnu.org>
11214 * eval.c (Fuser_variable_p, user_variable_p_eh)
11215 (lisp_indirect_variable): Functions deleted.
11216 (Fdefvar): Caller changed.
11218 * callint.c (Finteractive, Fcall_interactively):
11219 * minibuf.c (Fread_variable): Callers changed.
11221 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11223 * xdisp.c (set_cursor_from_row): If the display string appears in
11224 the buffer at position that is closer to point than the position
11225 after the display string, display the cursor on the first glyph of
11226 the display string. Fixes cursor display when a 'display' text
11227 property immediately follows invisible text. (Bug#11094)
11229 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11231 composite.c: use 'double' consistently
11232 * composite.c (get_composition_id): Use 'double' consistently
11233 instead of converting 'float' to 'double' and vice versa; this is
11234 easier to understand and avoids a GCC warning.
11236 2012-04-09 Glenn Morris <rgm@gnu.org>
11238 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11239 preparation for dumping it with emacs. (Bug#4789)
11240 (leimdir): New variable.

11258 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11260 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11261 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11262 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11263 objects, as mark_maybe_pointer will catch them otherwise.
11264 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11265 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11274 Support building on MS-Windows with libxml2.
11276 * makefile.w32-in (OBJ2): Add xml.$(O).
11277 (GLOBAL_SOURCES): Add xml.c.
11278 ($(BLD)/xml.$(O)): New dependency list.
11280 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11281 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11282 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11283 [!WINDOWSNT]: New macros.
11284 (init_libxml2_functions, libxml2_loaded_p): New functions.
11285 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11286 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11287 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11288 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11290 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11291 Call init_libxml2_functions before calling libxml2 functions.
11292 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11294 * emacs.c: Don't include libxml/parser.h.
11295 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11296 xmlCleanupParser directly.
11298 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11300 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11302 * indent.c (Fvertical_motion): If there is a display string at
11303 point, use it.vpos to compute how many lines to backtrack after
11304 move_it_to point. (Bug#11133)
11306 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11308 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11309 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11310 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11311 macros related to unification of CJK characters. For the details,
11312 see the discussion following the message here:
11313 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11315 2012-04-04 Chong Yidong <cyd@gnu.org>
11317 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11319 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11321 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11329 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11331 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11332 position we get to after a call to move_it_to fails the
11333 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11334 only if we wind up in a string from display property. (Bug#11063)
11336 * window.c (Fdelete_other_windows_internal): Invalidate the row
11337 and column information about mouse highlight, so that redisplay
11338 restores it after reallocating the glyph matrices. (Bug#7464)
11340 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11341 string comes from a `display' text property, use the buffer
11342 position of that property as if we actually saw that position in
11344 (move_it_by_lines): Remove the assertion that
11345 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11346 violated when there's a before-string at the beginning of a line.
11349 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11351 * xdisp.c (append_space_for_newline): If the default face was

11353 (extend_face_to_end_of_line): Use the remapped default face for
11354 extending the face to the end of the line.
11355 (display_line): Call extend_face_to_end_of_line when the default
11356 face was remapped. (Bug#11068)
11358 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11360 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11362 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

11378 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11379 (command_loop_1): Use it; inhibit selection update for

11384 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11386 2012-03-25 Kenichi Handa <handa@m17n.org>
11388 * dispextern.h (struct glyph): Change the bit length of
11389 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11391 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11393 * s/ms-w32.h (tzname): Include time.h before redirecting to

11402 !SYNC_INPUT. (Bug#11080)
11404 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11406 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11407 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11408 when fetching a multibyte character consumes more bytes than
11409 CHAR_BYTES returns, due to unification of CJK characters in
11410 string_char. (Bug#11073)
11412 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11414 * process.c (wait_reading_process_output): Handle pty disconnect
11415 by refraining from sending oneself a SIGCHLD (bug#10933).
11417 2012-03-22 Chong Yidong <cyd@gnu.org>
11419 * dispextern.h (struct it): New member string_from_prefix_prop_p.

11449 that is not from display property, accept the row as a "cursor
11450 row" if one of the string's character has a non-nil `cursor'
11451 property. Fixes cursor positioning when there are newlines in
11452 overlay strings, e.g. in icomplete.el. (Bug#11035)
11454 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11456 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11458 2012-03-12 Chong Yidong <cyd@gnu.org>
11460 * eval.c (inhibit_lisp_code): Rename from
11461 inhibit_window_configuration_change_hook; move from window.c.
11463 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11464 * window.c (run_window_configuration_change_hook)
11465 (syms_of_window): Callers changed.
11467 2012-03-11 Chong Yidong <cyd@gnu.org>
11469 * keymap.c (Fkey_description): Doc fix (Bug#9700).

11473 2012-03-10 Chong Yidong <cyd@gnu.org>
11475 * frame.c (other_visible_frames): Don't assume the selected frame
11476 is visible (Bug#10955).
11478 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11480 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11482 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11484 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11485 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11488 2012-03-03 Glenn Morris <rgm@gnu.org>
11490 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11492 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11495 position past the first glyph_row that ends at ZV. (Bug#10902)
11496 (redisplay_window, next_element_from_string): Fix typos in
11498 (redisplay_window): Pass to move_it_vertically the margin in
11499 pixels, not in screen lines.
11501 2012-03-02 Glenn Morris <rgm@gnu.org>
11503 * buffer.c (buffer-list-update-hook): Doc fix.
11505 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11507 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11508 push_it before setting up the iterator for the first overlay
11509 string, even if we have an empty string loaded.
11510 (next_overlay_string): If there's an empty string on the iterator
11511 stack, pop the stack. (Bug#10903)
11513 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11515 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11516 Suggested by Stefan Monnier in
11517 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11518 * alloc.c (widen_to_Lisp_Object): New static function.
11519 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11520 and widening them to Lisp_Objects. This would work even if
11521 USE_LSB_TAG is defined and wide integers are used, which might
11522 happen in a future version of Emacs.
11524 2012-02-25 Chong Yidong <cyd@gnu.org>
11526 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11529 * xselect.c (Fx_selection_exists_p): Doc fix.

11563 when computing $valmask.

11566 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11567 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11568 It's useless in that case, and it can cause problems on hosts
11569 that allocate halves of EMACS_INT values separately.
11570 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11571 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11572 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11573 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11574 it avoids undefined behavior on hosts where shifting right by more
11575 than the word width has undefined behavior.

11579 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11580 (Funhandled_file_name_directory, Ffile_name_as_directory)

11701 * character.c (char_width): Return EMACS_INT, not int.
11702 (char_width, c_string_width): Check for overflow when

12192 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12193 verifies glyph row's hash code--we have just reallocated the

12359 is set, removing the need for VIRT_ADDRESS_VARIES.
12360 (PURE_P): Use a more-efficient implementation that needs just one

12377 behave as if the cursor position were at the window margin.
12379 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12380 and the cursor position is out of bounds, behave as if the cursor
12381 position were at the window margin. (Bug#10075)
12383 2011-11-18 Chong Yidong <cyd@gnu.org>

12411 * dispnew.c (verify_row_hash): Call row_hash for computing the
12412 hash code of a row, instead of duplicating code from xdisp.c.
12414 * dispextern.h (row_hash): Add prototype.
12416 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12418 * frame.c (delete_frame): Don't delete the terminal when the last

12519 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12521 Avoid some portability problems by eschewing 'extern inline' functions.
12522 The trivial performance wins aren't worth the portability hassles; see
12523 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12525 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12565 (delete_all_subwindows): Rename to delete_all_child_windows.
12566 (Fdelete_other_windows_internal, Fset_window_configuration):
12567 Call delete_all_child_windows instead of delete_all_subwindows.

12573 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
12574 This is also needed for porting to any host where GC_MARK_STACK is
12575 not GC_MAKE_GCPROS_NOOPS.
12576 (which_symbols): Use it.
12578 2011-11-07 Kenichi Handa <handa@m17n.org>

12591 * xmenu.c (cleanup_widget_value_tree): New function.
12592 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
12593 calling free_menubar_widget_value_tree directly (Bug#9830).

12599 (window_box_width, window_box_left, window_box_left_offset)
12600 (window_box_right, window_box_right_offset): Declare extern.
12601 Otherwise, these inline functions do not conform to C99 and
12602 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12603 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12604 * intervals.c (adjust_intervals_for_insertion)
12605 (adjust_intervals_for_deletion): Now extern, because otherwise the

12607 (static_offset_intervals): Remove.
12608 (offset_intervals): Rewrite using the old contents of
12609 static_offset_intervals. The old version didn't conform to C99
12610 because an extern inline function contained a reference to an
12611 identifier with static linkage.

12633 (Fwindow_vscroll): Doc fix.

12635 argument, since it makes no sense to pass a live window and for
12636 consistency with window-child.

12677 official. Move initialization of image_cache_refcount and
12678 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

12846 (w32font_open_internal, compute_metrics):
12847 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12848 instead of calling the "wide" APIs directly.

12923 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12924 * editfns.c: Rewrite current-time-zone so that it invokes
12925 the equivalent of (format-time-string "%Z") to get the time zone name.
12926 This fixes a bug when the time zone name contains characters that
12927 need converting from the system time locale to Emacs internal format.
12928 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12929 that patch fixed format-time-string to do the conversion, but
12930 I forgot to fix current-time-zone.
12931 (format_time_string): New function, containing most of
12932 what Fformat_time_string used to contain.
12933 (Fformat_time_string): Rewrite in terms of format_time_string.
12934 This doesn't change this function's behavior.

12936 This fixes the bug reported by Michael Schierl in
12937 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12938 Jason Rumney's 2007-06-07 change worked around this bug, but
12940 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12942 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12944 * xdisp.c (start_display): If the character at POS is displayed
12945 via a display vector, reset IT->current.dpvec_index to zero.
12946 (try_window_reusing_current_matrix): If a line ends in a display
12947 vector or the next line starts in a display vector, continue
12948 redrawing the window even though the character position of
12949 start_row was reached.
12952 2011-10-18 Chong Yidong <cyd@gnu.org>
12954 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12955 with nobreak-char-display too.
12957 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12959 Fix part 3 of bug#9771.
12960 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12961 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12962 non-neutral characters if the current character is a paragraph
12963 separator (a.k.a. Newline). This avoids running the same
12964 expensive loop twice, once when we consume the preceding newline
12965 and the other time when the line actually needs to be displayed.
12966 Avoid the loop when we see neutrals on the base embedding level
12967 following a character whose directionality is the same as the
12968 paragraph's. This avoids running the expensive loop when a line
12969 ends in a long sequence of neutrals, like control characters.
12970 Add assertion against STRONG_AL type. Slightly rearrange code
12971 that determines the type of a neutral given the first non-neutral
12973 (bidi_level_of_next_char): Set next_en_pos to zero when
12974 invalidating its info.
12976 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12978 * xdisp.c (push_display_prop): Determine whether to record string
12979 or buffer position by IT->string, not by IT->method. Allow
12980 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12981 (move_it_vertically_backward): Don't look for character position
12982 immediately after the newline when in a continuation line.
12985 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12987 * window.c (coordinates_in_window): Rewrite and delabelize
12988 vertical border check. (Bug#5357) (Bug#9618)
12990 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12992 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12993 errors in XSetWindowBorder (bug#9310).
12995 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12997 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12998 avoid crash when xmalloc overrun checking is enabled.
13000 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13002 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13003 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13004 cursor motion with <left> and <right> arrow keys.
13006 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13007 some callers set that themselves.
13009 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13011 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13012 display string and the previous row comes from the same string and
13013 is empty. (Bug#9739) (Bug#9738)
13015 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13017 * doc.c (get_doc_string): Encode file name (bug#9735).
13019 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13021 * bidi.c (bidi_level_of_next_char):
13022 * xdisp.c (get_visually_first_element): Remove old incorrect
13023 comments regarding the Unicode Line Separator character.
13025 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13027 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13029 * alloc.c (Fgc_status): Do not access beyond zombies array
13030 boundary if nzombies > MAX_ZOMBIES.
13031 * alloc.c (dump_zombies): Add missing format specifier.
13033 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13035 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13036 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13038 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13039 Some packages use them to denote characters with modifiers.
13041 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13043 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13044 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13045 matching a pp-number. Rename parameter var to var1.
13047 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13049 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13051 2011-10-08 Glenn Morris <rgm@gnu.org>
13053 * callint.c (Fcall_interactively): Give a more explicit error for the
13054 'c' case with a non-character input. (Bug#8479)
13056 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13058 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13060 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13061 lines that are hscrolled on the left.
13063 * dispnew.c (buffer_posn_from_coords): Account for a possible
13064 presence of header-line. (Bug#4426)
13066 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13068 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13069 Don't advertise functionality which we discourage or doesn't work.
13071 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13073 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13074 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13075 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13076 this makes Emacs dump core during garbage collection on rare
13077 occasions. sizeof is obviously inferior to offsetof here, so
13078 stick with offsetof.
13079 (GC_POINTER_ALIGNMENT): New macro.
13080 (mark_memory): Omit 3rd (offset) arg; caller changed.
13081 Don't assume EMACS_INT alignment is the same as pointer alignment.
13083 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13085 * keyboard.c (read_key_sequence_remapped): New var.
13086 (read_key_sequence): Compute remapping in the right buffer.
13087 (command_loop_1): Use read_key_sequence's remapping directly.
13089 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13091 * dired.c (file_name_completion): Don't expand file name.
13092 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13093 before checking file name handler.
13095 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13096 they've been requested explicitly (bug#9591).
13098 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13100 * keymap.c (Fsingle_key_description): Use make_specified_string
13101 instead of build_string to build string from push_key_description.
13104 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13106 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13107 This fixes a Y2038 bug on 64-bit hosts.
13108 * buffer.c (reset_buffer):
13109 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13110 (Fclear_buffer_auto_save_failure):
13111 Use 0, not -1, to represent an unset failure time, since time_t
13112 might not be signed.
13114 Remove dependency on glibc malloc internals.
13115 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13116 Move back here from lisp.h, but with their new implementations.
13117 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13118 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13119 * charset.c (charset_table_init): New static var.
13120 (syms_of_charset): Use it instead of xmalloc. This removes a
13121 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13122 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13123 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13124 Move back to alloc.c.
13125 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13126 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13128 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13130 * nsterm.m (windowDidResize): Call x_set_window_size only when
13131 ns_in_resize is true. Otherwise set pixelwidth/height and
13132 call change_frame_size (Bug#9628).
13134 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13136 Port --enable-checking=all to Fedora 14 x86-64.
13137 * charset.c (syms_of_charset): Also account for glibc malloc's
13138 internal overhead when calculating the initial malloc maximum.
13140 Port --enable-checking=all to Fedora 14 x86.
13141 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13143 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13144 (overrun_check_realloc, overrun_check_free):
13145 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13146 That way, xmalloc returns a properly-aligned pointer even if
13147 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13148 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13149 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13150 into account when calculating the initial malloc maximum.
13151 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13152 Move here from alloc.c, so that charset.c can use it too.
13153 Properly align; the old code wasn't right for common 32-bit hosts
13154 when configured with --enable-checking=all.
13155 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13156 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13158 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13160 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13163 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13165 * xdisp.c (compute_display_string_end): If there's no display
13166 string at CHARPOS, return -1.
13168 * bidi.c (bidi_fetch_char): When compute_display_string_end
13169 returns a negative value, treat the character as a normal
13170 character not covered by a display string. (Bug#9624)
13172 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13174 * lread.c (Fread_from_string): Fix typo in docstring.
13176 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13178 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13179 newline, reseat the iterator instead of bidi-iterating there one
13180 character at a time. (Bug#9610)
13181 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13182 TO_CHARPOS if the bidi iterator is at base embedding level.
13184 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13186 * lread.c (readevalloop): Use correct code for NBSP.
13187 (read1): Likewise. (Bug#9608)
13189 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13191 * dbusbind.c (Fdbus_register_signal): When service is not
13192 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13194 2011-09-25 Glenn Morris <rgm@gnu.org>
13196 * buffer.c (truncate-lines): Doc fix.
13198 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13200 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13201 (Fset_window_next_buffers): Doc fix.
13203 2011-09-24 Glenn Morris <rgm@gnu.org>
13205 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13207 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13209 Fix minor problems found by static checking.
13210 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13211 * indent.c (Fvertical_motion): Fix == vs = typo.
13213 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13215 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13216 Default value is now t. Doc fix.
13218 * indent.c (Fvertical_motion): Compute and apply the overshoot
13219 logic when moving up, not only when moving down. Fix the
13220 confusing name and values of the it_overshoot_expected variable;
13221 logic changes accordingly. (Bug#9254) (Bug#9549)
13223 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13224 CHARPOS is covered by a display string which includes newlines.
13225 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13226 is covered by a display string with embedded newlines.
13228 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13230 * dbusbind.c (Fdbus_register_signal): Add match rule to
13231 Vdbus_registered_objects_table. (Bug#9581)
13232 (Fdbus_register_method, Vdbus_registered_objects_table):
13235 2011-09-24 Jim Meyering <meyering@redhat.com>
13237 do not ignore write error for any output size
13238 The previous change was incomplete.
13239 While it makes emacs --batch detect the vast majority of stdout
13240 write failures, errors were still ignored whenever the output size is
13241 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13242 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13243 && echo FAIL: ignored write error
13244 FAIL: ignored write error
13245 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13246 && echo FAIL: ignored write error
13247 FAIL: ignored write error
13248 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13250 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13252 * emacs.c (Fkill_emacs): In noninteractive mode exit
13253 non-successfully if a write error occurred on stdout. (Bug#9574)
13255 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13257 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13260 * dispextern.h (struct it): Update the comment documenting what
13263 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13265 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13266 a display string, extend search for cursor position to end of row.
13267 (find_row_edges): If the row ends in a newline from a display
13268 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13269 Handle the case of a display string with multiple newlines.
13270 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13271 non-empty line. Fixes confusing cursor motion with arrow keys at
13272 the beginning of a line that starts with whitespace.
13274 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13276 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13279 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13281 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13282 boolean (Bug#9154).
13284 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13286 * xdisp.c (display_line): Record maximum and minimum buffer
13287 positions even if no glyphs were produced (e.g., by a zero-width
13288 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13289 buffer positions that will be removed from the glyph row because
13291 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13292 column is beyond frame width: don't subtract 1 "pixel" when
13293 computing width of the stretch.
13294 (reseat_at_next_visible_line_start): Undo the change made on
13295 2011-09-17 that saved paragraph information and restored it after
13296 the call to `reseat'. (Bug#9545)
13298 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13300 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13301 and turn window cursor on if cleared (Bug#9415).
13303 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13305 * search.c (boyer_moore): Take unibyte characters from pattern
13306 literally. (Bug#9458)
13308 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13310 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13312 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13314 Fix minor problem found by static checking.
13315 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13316 initialized, to pacify gcc -Wuninitialized.
13318 * fileio.c: Report proper errno when syscall falls.
13319 (Finsert_file_contents): Save and restore errno,
13320 so that report_file_error outputs the correct diagnostic.
13321 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13323 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13325 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13327 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13329 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13330 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13332 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13334 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13335 about the current paragraph and restore it after the call to reseat.
13337 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13338 (bidi_find_paragraph_start): Search back for paragraph beginning
13339 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13340 (bidi_move_to_visually_next): Only trigger paragraph-related
13341 computations when the last character is a newline or at EOB, not
13342 just any NEUTRAL_B. (Bug#9470)
13344 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13345 truncated lines if point is covered by a display string. (Bug#9524)
13347 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13349 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13350 (cons_to_x_long): New function.
13351 (lisp_data_to_selection_data): Use it. Correct the test for
13352 short-versus-long data; it was negated. Break out of vector
13353 loop, for efficiency, when a long datum is discovered.
13355 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13357 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

13377 * term.c (encode_terminal_code):
13378 * composite.c (composition_update_it, get_composition_id):
13379 * xdisp.c (get_next_display_element)
13380 (fill_composite_glyph_string): Add comments about special meaning
13381 of TAB characters in a composition.
13383 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13385 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13386 This occurs when processing a multibyte format.
13387 Problem reported by Wolfgang Jenker.
13389 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13391 * xdisp.c (try_cursor_movement): Only check for exact match if
13392 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13394 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13396 Remove unused external symbols.
13397 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13398 * xdisp.c (calc_pixel_width_or_height): Now static.
13399 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13400 * indent.c (check_display_width):
13401 * w32term.c: Fix comment to match code.
13402 * xterm.c, xterm.h (x_catching_errors): Remove.
13404 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13406 * xselect.c: Use signed conversions more consistently (Bug#9498).
13407 (selection_data_to_lisp_data): Assume incoming selection data are
13408 signed integers, not unsigned. This is to be consistent with
13409 outgoing selection data, which was modified to use signed integers
13410 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13411 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13412 expects long, not unsigned long.
13414 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13416 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13417 computation of loop end. Reported by Johan Bockgård
13420 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13422 * frame.c (Fother_visible_frames_p): Function deleted.
13424 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13426 * indent.c (compute_motion): Process display vector front to back
13427 rather than the other way around. (Bug#2496)
13429 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13431 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13433 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13435 * minibuf.c (Fread_from_minibuffer): Doc fix.
13437 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13439 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13440 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13442 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13444 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13445 value for non-existent files.
13447 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13449 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13450 set its "size" to -1. This will set the modtime_size field of
13451 the corresponding buffer to -1, which is what
13452 verify-visited-file-modtime expects for files that do not exist.
13455 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13457 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13459 * lisp.h: ... from here. push_key_description is no longer
13460 defined in keyboard.c, so its declaration should not be in
13461 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13462 logically belongs with push_key_description.
13464 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13466 * buffer.h: Include <sys/types.h> instead of <time.h>.
13467 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13468 Problem reported by Herbert J. Skuhra.
13470 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13472 * xml.c (parse_region): Make the parsing work for
13473 non-comment-starting XML files again (bug#9144).
13475 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13477 * image.c (gif_load): Fix calculation of bottom and right corner.
13480 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13482 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13483 redisplay in small windows.
13485 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13487 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13489 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13491 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13492 Operate on live windows only.
13494 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13496 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13498 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13500 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13501 only under bidi iteration.
13503 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13505 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13507 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13509 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13510 Without this fix, the command to link temacs failed due to an
13511 undefined symbol __builtin_isnan. This is because
13512 /usr/include/iso/math_c99.h #defines isnan(x) to
13513 __builtin_isnan(x), but the bundled gcc, which identifies itself
13514 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13516 * floatfns.c (isnan): #undef, and then #define to a clone of
13518 (Fisnan): Always define, since it's always available now.
13519 (syms_of_floatfns): Always define isnan at the Lisp level.
13521 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13523 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13525 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13527 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13528 The previous code assumed that file offsets (off_t values) fit in
13529 EMACS_INT variables, which is not true on typical 32-bit hosts.
13530 The code messed up by falsely reporting buffer overflow in cases
13531 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13532 when "big" contains more than 2**29 bytes, even though this
13533 inserts just one byte and does not overflow the buffer.
13534 (Finsert_file_contents): Store file offsets as off_t
13535 values, not as EMACS_INT values. Check for overflow when
13536 converting between EMACS_INT and off_t. When checking for
13537 buffer overflow or for overlap, take the offsets into account.
13538 Don't use EMACS_INT for small values where int suffices.
13539 When checking for overlap, fix a typo: ZV was used where
13540 ZV_BYTE was intended.
13541 (Fwrite_region): Don't assume off_t fits into 'long'.
13542 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13544 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13546 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13548 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13550 sprintf-related integer and memory overflow issues (Bug#9412).
13552 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13553 (esprintf, exprintf, evxprintf): New functions.
13554 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13555 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13556 (modify_event_symbol): Do not assume that the length of
13557 name_alist_or_stem is safe to alloca and fits in int.
13558 (Fexecute_extended_command): Likewise for function name and binding.
13559 (Frecursion_depth): Wrap around reliably on integer overflow.
13560 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13561 since some callers pass EMACS_INT values.
13562 (Fsingle_key_description): Don't crash if symbol name contains more
13563 than MAX_ALLOCA bytes.
13564 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13565 (get_minibuffer): Arg is now EMACS_INT, not int.
13566 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13567 (esprintf, exprintf, evxprintf): New decls.
13568 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13570 * dbusbind.c (signature_cat): New function.
13571 (xd_signature, Fdbus_register_signal):
13572 Do not overrun buffer; instead, report string overflow.
13574 * dispnew.c (add_window_display_history): Don't overrun buffer.
13575 Truncate instead; this is OK since it's just a log.
13577 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13578 even if the time zone offset is outlandishly large.
13579 Don't mishandle offset == INT_MIN.
13581 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13582 when creating daemon; the previous buffer-overflow check was incorrect.
13584 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13585 which has the guts of the old verror function.
13587 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13588 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13590 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13591 (font_unparse_xlfd): Don't blindly alloca long strings.
13592 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13593 fits in int, when using sprintf. Use single snprintf to count
13594 length of string rather than counting it via multiple sprintfs;
13595 that's simpler and more reliable.
13596 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13597 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13598 sprintf, in case result does not fit in int.
13600 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13601 (fontset_from_font): Print it.
13603 * frame.c (tty_frame_count): Now printmax_t, not int.
13604 (make_terminal_frame, set_term_frame_name): Print it.
13605 (x_report_frame_params): In X, window IDs are unsigned long,
13606 not signed long, so print them as unsigned.
13607 (validate_x_resource_name): Check for implausibly long names,
13608 and don't assume name length fits in 'int'.
13609 (x_get_resource_string): Don't blindly alloca invocation name;
13610 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13613 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13614 (xg_check_special_colors, xg_set_geometry):
13615 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13617 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13618 Use esprintf, not sprintf, in case result does not fit in int.
13620 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13621 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13622 it as a large positive number.
13623 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13624 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13626 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13627 in case result does not fit in int.
13629 * print.c (float_to_string): Detect width overflow more reliably.
13630 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13631 buffer overrun. Don't assume list length fits in 'int'. Treat
13632 print length of 0 as 0, not as infinity; to be consistent with other
13633 uses of print length in this function. Don't overflow print length
13634 index. Don't assume hash table size fits in 'long', or that
13635 vectorlike size fits in 'unsigned long'.
13637 * process.c (make_process): Use printmax_t, not int, to format
13638 process-name gensyms.
13640 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13642 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13643 to avoid potential buffer overrun.
13645 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13646 if X resource line is longer than 512 bytes.
13648 * xfns.c (x_window): Make sprintf buffer a bit bigger
13649 to avoid potential buffer overrun.
13651 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13653 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13655 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13657 Integer overflow fixes for scrolling, etc.
13658 Without these, Emacs silently mishandles large integers sometimes.
13659 For example, "C-u 4294967297 M-x recenter" was treated as if
13660 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13662 * xdisp.c (try_window_id): Check Emacs fixnum range before
13663 converting to 'int'.
13665 * window.c (window_scroll_line_based, Frecenter):
13666 Check that an Emacs fixnum is in range before assigning it to 'int'.
13667 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13668 values converted from Emacs fixnums.
13669 (Frecenter): Don't wrap around a line count if it is out of 'int'
13670 range; instead, treat it as an extreme value.
13671 (Fset_window_configuration, compare_window_configurations):
13672 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13674 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13675 that can exceed INT_MAX. Check that EMACS_INT value is in range
13676 before assigning it to the (possibly-narrower) index.
13677 (match_limit): Don't assume that a fixnum can fit in 'int'.
13679 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13682 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13683 (Fvertical_motion): Don't wrap around LINES values that don't fit
13684 in 'int'. Instead, treat them as extreme values. This is good
13685 enough for windows, which can't have more than INT_MAX lines anyway.
13687 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13689 * Require libxml/parser.h to avoid compilation warning.
13691 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13693 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13694 since this reportedly can destroy thread storage.
13696 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13698 * syntax.c (find_defun_start): Update all cache variables if
13699 exiting early (Bug#9401).
13701 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13703 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13705 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13706 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13707 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13709 * term.c (tty_append_glyph): New function.
13710 (produce_stretch_glyph): Static function and its prototype deleted.
13712 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13715 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13717 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13718 when checking :margin (Bug#9390).
13719 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13720 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13721 so that the name doesn't mislead. All uses changed.
13723 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13725 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13728 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13730 * xdisp.c (move_it_to): Don't bail out early when reaching
13731 position beyond to_charpos, if we are scanning backwards.
13732 (move_it_vertically_backward): When DY == 0, make sure we get to
13733 the first character in the line after the newline.
13735 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13737 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13738 (ccl_driver): Do not generate an out-of-range pointer.
13739 (Fccl_execute_on_string): Remove unnecessary check for
13740 integer overflow, noted by Stefan Monnier in
13741 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13742 Remove a FIXME that didn't need fixing.
13743 Simplify the newly-introduced buffer reallocation code.
13745 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13747 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13749 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13751 Integer and memory overflow issues (Bug#9196).
13753 * doc.c (get_doc_string): Rework so that
13754 get_doc_string_buffer_size is the actual buffer size, rather than
13755 being 1 less than the actual buffer size; this makes xpalloc more
13758 * image.c (x_allocate_bitmap_record, cache_image):
13759 * xselect.c (Fx_register_dnd_atom):
13760 Simplify previous changes by using xpalloc.
13762 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13763 since either will do and ptrdiff_t is convenient with xpalloc.
13765 * charset.c (charset_table_size)
13766 (struct charset_sort_data.priority): Now ptrdiff_t.
13767 (charset_compare): Don't overflow if priorities differ greatly.
13768 (Fsort_charsets): Don't assume list length fits in int.
13769 Check for size-calculation overflow when allocating sort data.
13770 (syms_of_charset): Allocate an initial charset table that is
13771 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13773 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13775 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13776 The actual value is always <= INT_MAX, and leaving it unsigned made
13777 overflow checking harder.
13779 * dispextern.h (struct glyph_matrix.rows_allocated)
13780 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13781 with xpalloc. The values are still always <= INT_MAX.
13783 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13785 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13786 (SAFE_NALLOCA): New macro.
13788 * region-cache.c (struct boundary.pos, find_cache_boundary)
13789 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13790 (set_cache_region, invalidate_region_cache)
13791 (revalidate_region_cache, know_region_cache, region_cache_forward)
13792 (region_cache_backward, pp_cache):
13793 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13794 so that ptrdiff_t * can be passed to xpalloc.
13795 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13796 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13797 (pp_cache): Don't assume cache_len fits in int.
13798 * region-cache.h: Adjust extern decls to match.
13800 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13801 EMACS_INT, since either will do, for xpalloc.
13803 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13804 (xnmalloc, xnrealloc, xpalloc): New functions.
13806 * bidi.c (bidi_shelve_header_size): New constant.
13807 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13808 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13810 * bidi.c (bidi_cache_shrink):
13811 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13813 Don't update size of array until after memory allocation succeeds,
13814 because xmalloc/xrealloc may not return.
13815 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13816 now that we have proper integer overflow checking.
13817 (record_overlay_string, overlay_strings): Catch overflows when
13818 calculating size of overlay_str_buf.
13820 * callproc.c (Fcall_process): Check for size overflow when
13821 calculating size of args2.
13822 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13823 Normally we prefer signed values, but sticking with ptrdiff_t would
13824 require adding more-complicated checks.
13826 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13827 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13828 Redo buffer-overflow calculations to avoid integer overflow.
13829 Add a FIXME comment where memory seems to be over-allocated.
13831 * character.c (Fstring): Check for size-calculation overflow.
13833 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13834 unnecessary integer overflow. Check for size overflow.
13835 (encode_coding_object): Don't update size until xmalloc succeeds.
13837 * composite.c (get_composition_id): Check for overflow in glyph
13838 length calculations.
13840 Integer and memory overflow fixes for display code.
13841 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13842 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13843 (scrolling_window): Check for overflow in size calculations.
13844 (line_draw_cost, realloc_glyph_pool, add_row_entry):
13845 Don't assume glyph table len fits in int.
13846 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
13847 (row_table_size): Now ptrdiff_t, not int.
13848 (scrolling_window): Avoid overflow in size calculations.
13849 Don't update size until allocation succeeds.
13850 * fns.c (concat): Check for overflow in size calculations.
13851 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
13852 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
13853 (NEXT_ALMOST_PRIME_LIMIT): New constant.
13855 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13856 (get_doc_string): Check for size calculation overflow.

13867 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13869 * emacs.c (main): Do not reallocate argv, since there is a null at
13870 the end that can be overwritten, and this way there's no need to
13871 worry about size-calculation overflow.
13872 (sort_args): Check for size-calculation overflow.

13881 (x_set_alpha): Do not assume XINT fits in int.
13883 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13884 This is for the members text_lines, text_cols, total_lines, total_cols,
13885 where the system imposes an 'int' limit.

13894 Check for size-calculation overflow.
13895 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13896 do, as we prefer signed integers.

13952 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13953 for command line length. Do not attempt to address one before the
13954 beginning of an array, as that's not portable.

13984 Check for size calculation overflow.
13985 (cache_face): Treat size calculation overflows as if they were
13986 memory exhaustion (the usual treatment), rather than aborting.
13988 * xfns.c (x_encode_text, x_set_name_internal)
13989 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13990 sizes, since they can exceed INT_MAX in size. Check for size

13994 (xg_select): Check for size calculation overflow.
13995 Don't update size until alloc done.
13997 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13998 as sprintf is limited to int lengths.
14000 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14001 (X_LONG_MIN): New macros.
14002 Use them to make the following changes clearer.
14003 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14004 This change doesn't affect the value now, but it may help remind
14005 future maintainers not to raise the value too much later.
14006 (SELECTION_QUANTUM): Remove, replacing with ...
14007 (selection_quantum): ... new function, which avoids overflow.
14009 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14010 assumption that selection length fits in 'int'.
14011 (x_reply_selection_request, x_handle_selection_request)
14012 (x_get_window_property, receive_incremental_selection)

14027 Don't store size until memory allocation succeeds.
14028 (x_get_window_property): Plug memory leak on memory exhaustion.
14029 Don't double-block input; malloc is safe here. Don't assume 2**34
14030 - 4 fits in unsigned long. Add an xassert to check
14031 XGetWindowProperty overflow. Be more careful about overflow
14032 calculations, and distinguish size from memory overflow better.
14033 (receive_incremental_selection): When tracing, don't assume
14034 unsigned int is less than INT_MAX.
14035 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14039 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14040 result parameters unless successful. Rely on cons_to_unsigned
14041 to report problems with elements; the old code wasn't right anyway.
14042 (x_check_property_data): Check for int overflow; we cannot use
14043 a wider type due to X limits.

14076 * lisp.h (hash_lookup, hash_put):
14077 * minibuf.c (Ftest_completion):
14078 Use ptrdiff_t for hash table indexes, not int (which is too
14079 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14080 32-bit --with-wide-int hosts).
14082 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14083 Add a FIXME comment about memory leaks.

14091 with outlandish widths.
14092 * character.h (sanitize_tab_width): Rename from sanitize_width,
14093 now that we have two such functions. All uses changed.

14111 * xterm.c: Don't go over XClientMessageEvent limit.
14112 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14113 (x_send_scroll_bar_event): Likewise. Check that the size does not
14114 exceed limits imposed by XClientMessageEvent, as well as the usual
14115 ptrdiff_t and size_t limits.

14118 (make_lispy_movement): Use same integer type in forward decl
14119 that is used in the definition.
14120 (read_key_sequence, keyremap_step):
14121 Change bufsize argument back to int, undoing my 2011-03-30 change.
14122 We prefer signed types, and int is wide enough here.
14123 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14124 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14125 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14126 length, not size_t. Use ptrdiff_t for index, not int.
14127 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14128 possibility of integer overflow.

14156 Prefer int to unsigned where either will do.
14157 (tiff_handler): New function, combining the cores of the
14158 old tiff_error_handler and tiff_warning_handler.
14159 This function is rewritten to use vsnprintf and thereby avoid
14160 stack buffer overflows. It uses only the features of vsnprintf
14161 that are common to both POSIX and native Microsoft.
14162 (tiff_error_handler, tiff_warning_handler): Use it.
14163 (tiff_load, gif_load, imagemagick_load_image):
14164 Don't assume :index value fits in 'int'.
14165 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14166 (imagemagick_load_image): Check that crop parameters fit into
14167 the integer types that MagickCropImage accepts. Don't assume
14168 Vimagemagick_render_type has a nonnegative value. Don't assume
14169 size_t fits in 'long'.
14170 (gs_load): Use printmax_t to print the widest integers possible.

14184 (handle_single_display_spec): If the display spec is of the form
14185 `(space ...)', and specifies display in the text area, return 2
14187 (try_cursor_movement): Check for the need to scroll more
14188 accurately, and prefer exact match for point under bidi.
14189 Don't advance `row' beyond the last row of the window.

14207 buffers, return left-to-right.
14208 (set_cursor_from_row): Consider candidate row a win if its glyph

14210 positioning on the newline at EOL of R2L text within L2R
14211 paragraph, and vice versa.
14212 (try_cursor_movement): Check continued rows, in addition to
14213 continuation rows. Fixes unwarranted scroll when point enters a
14214 continued line of R2L text within an L2R paragraph, or vice versa.
14215 (cursor_row_p): Consider the case of point being equal to
14216 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

14242 * xdisp.c (redisplay_window): When computing centering_position,
14243 account for the height of the header line. (Bug#8874)
14245 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14246 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14247 candidate is selected by the mouse, and that candidate has a
14248 composed character under the mouse.
14250 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14251 coordinates reported by pos-visible-in-window-p for a composed
14252 character in column zero.

14260 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14261 consider it a hit if to_charpos is anywhere in the range of the
14262 composed buffer positions.
14264 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14266 * image.c (gif_load): Don't assume that each subimage has the same
14267 dimensions as the base image. Handle disposal method that is
14268 "undefined" by the gif spec (Bug#9335).
14270 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14272 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14284 with a composed character.
14286 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14288 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14289 character bidirectional type, use STRONG_L instead. Fixes crashes
14290 in a buffer produced by `describe-categories'.
14292 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14293 members before the level stack, so they would be saved and
14294 restored when copying iterator state. Fixes incorrect reordering
14295 around TABs covered by display properties.
14297 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14299 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
14301 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
14303 * eval.c (internal_condition_case, internal_condition_case_1)
14304 (internal_condition_case_2, internal_condition_case_n):
14305 Remove unnecessary aborts (Bug#9081).
14307 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14309 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14310 has no `load' handler, try opening the file locally. (Bug#9311)
14312 2011-08-16 Ken Brown <kbrown@cornell.edu>
14314 * gmalloc.c: Expand comment.
14316 2011-08-16 Eli Zaretskii <eliz@gnu.org>
14318 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
14319 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
14321 2011-08-16 Ken Brown <kbrown@cornell.edu>
14323 Fix memory allocation problems in Cygwin build (Bug#9273).
14325 * unexcw.c ( __malloc_initialized): Declare external variable.

14328 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
14330 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
14332 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
14333 in the static heap.
14334 [CYGWIN] (special_realloc): New function.
14335 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
14336 requests to realloc storage in the static heap.
14338 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
14340 * bidi.c (bidi_initialize): Remove unused local.
14342 2011-08-15 Eli Zaretskii <eliz@gnu.org>
14345 * biditype.h: Remove file.

14347 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
14349 * dispextern.h: Fix a typo in the comment to bidi_type_t.
14351 * chartab.c: Improve commentary for the uniprop_table API.
14353 * bidi.c (bidi_paragraph_init): Support zero value of
14354 bidi_ignore_explicit_marks_for_paragraph_level.
14355 (bidi_initialize): Use uniprop_table instead of including
14356 biditype.h and bidimirror.h.
14358 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
14359 coordinates of the iterator when restoring from ppos_it.
14362 2011-08-14 Kenichi Handa <handa@m17n.org>
14364 * process.c (create_process): Call setup_process_coding_systems
14365 after the pid of the process is set to -1 (Bug#8162).
14367 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14369 * xdisp.c (move_it_in_display_line_to): Don't invoke
14370 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14371 ppos_it. Fixes vertical cursor motion when line beginning is
14372 covered by an image. (Bug#9296)
14374 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14376 * nsterm.h (ns_run_ascript): Declare.
14377 (NSAPP_DATA2_RUNASSCRIPT): Define.
14379 * nsfns.m (as_script, as_result, as_status): New static variables.
14380 (ns_run_ascript): New function.
14381 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14382 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14383 the event loop. Get status from as_status (Bug#7276).
14385 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14386 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14387 the event loop (Bug#7276).
14389 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14391 * gnutls.c (QCgnutls_bootprop_priority)
14392 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14393 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14394 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14395 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14396 (QCgnutls_bootprop_verify_hostname_error)
14397 (QCgnutls_bootprop_callbacks_verify): Rename from
14398 Qgnutls_bootprop_..., all uses changed.
14400 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
14403 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
14405 * xfaces.c (Qframe_set_background_mode): Now static.
14406 * dispextern.h (Qframe_set_background_mode): Remove decl.

14410 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
14412 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14413 (Fnetwork_interface_list): Allocate in increments of bytes instead
14414 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14415 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14417 (struct ifflag_def): notrailers is smart on OSX.
14418 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14419 Get hardware address with getifaddrs if available.
14421 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14423 * xdisp.c (iterate_out_of_display_property): xassert that
14424 IT->position is set to within IT->object's boundaries. Break from
14425 the loop as soon as EOB is reached; avoids infloops in redisplay
14426 when IT->position is set up wrongly due to some bug.
14427 Set IT->current to match the bidi iterator unconditionally.
14428 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14429 entry. Force push_it to save on the stack the current
14430 buffer/string position, to be restored by pop_it. Fix flags in
14431 the iterator structure wrt the object coming from a display
14432 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14433 properties. (Bug#9284)
14435 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14437 * fontset.c (fontset_get_font_group): Add proper type checks.
14440 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14442 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
14443 and LC_VERSION_MIN_MACOSX.
14444 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
14445 (dump_it) [LC_FUNCTION_STARTS]: Use it.
14447 2011-08-08 Eli Zaretskii <eliz@gnu.org>
14449 * xdisp.c (forward_to_next_line_start): Allow to use the
14450 no-display-properties-and-no-overlays under bidi display.
14451 Set disp_pos in the bidi iterator to avoid searches for display
14452 properties and overlays.
14454 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14456 * editfns.c (Fset_time_zone_rule): Document relationship with the

14460 the font entity extracted from the cache (Bug#8109).
14462 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14464 * composite.c (autocmp_chars): Don't reset point. That is done by
14465 restore_point_unwind (Bug#5984).
14467 2011-08-07 Juri Linkov <juri@jurta.org>
14469 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14470 to show the arg `TIME' instead of `TIMEVAL'.
14472 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14474 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14475 display property strides EOL and includes a newline, as in
14476 longlines-mode. (Bug#9254)
14477 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14478 word-wrap under bidirectional display. (Bug#9224)
14480 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14481 is non-zero, even if the data buffer is NULL. Fixes a crash in
14482 vertical-motion with longlines-mode. (Bug#9254)
14484 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14486 * bidi.c <bidi_cache_total_alloc>: Now static.
14487 (bidi_initialize): Initialize bidi_cache_total_alloc.
14489 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14492 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14493 amount allocated this far in `bidi_cache_total_alloc'.
14494 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14495 non-zero, only free the data buffer without restoring the cache
14496 contents. All callers changed.
14498 * dispextern.h (bidi_unshelve_cache): Update prototype.
14500 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14501 (move_it_in_display_line, move_it_to)
14502 (move_it_vertically_backward, move_it_by_lines): Replace the call
14503 to xfree to an equivalent call to bidi_unshelve_cache.
14504 (move_it_in_display_line_to): Fix logic of returning
14505 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14507 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14509 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14510 came from a string character with a `cursor' property. (Bug#9229)
14512 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14514 * Makefile.in (LIB_PTHREAD): New variable.
14515 (LIBES): Add LIB_PTHREAD (Bug#9216).
14517 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14518 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14520 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14522 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14524 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14526 * xterm.c (x_find_topmost_parent): New function.
14527 (x_set_frame_alpha): Find topmost parent window with
14528 x_find_topmost_parent and set the property there also (bug#9181).
14529 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14531 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14533 * callproc.c (Fcall_process): Avoid vfork clobbering
14534 the local vars buffer, coding_systems, current_dir.
14536 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14538 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14540 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14542 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14543 so that it is not optimized away.
14545 * xdisp.c (compute_display_string_pos): Remove unused local.
14547 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14549 Fix slow cursor motion and scrolling in large buffers with
14550 selective display, like Org Mode buffers. (Bug#9218)
14552 * dispextern.h (struct bidi_it): New member disp_prop_p.
14554 * xdisp.c: Remove one-slot cache of display string positions.
14555 (compute_display_string_pos): Accept an additional argument
14556 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14557 for a display string or property. If found, set DISP_PROP_P
14560 * bidi.c (bidi_fetch_char): Accept an additional argument
14561 DISP_PROP_P, and pass it to compute_display_string_pos.
14562 Only handle text covered by a display string if DISP_PROP_P is returned
14563 non-zero. All callers of bidi_fetch_char changed.
14565 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14567 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14569 2010-12-03 Don March <don@ohspite.net>
14571 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14572 last character M-[char] is translated to ESC [char] (bug#7541).
14574 2011-08-02 Kenichi Handa <handa@m17n.org>
14576 * lisp.h (uniprop_table): Extern it.
14578 * chartab.c (uniprop_table): Make it non-static.
14580 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14582 * xdisp.c (forward_to_next_line_start): Accept additional argument
14583 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14585 (reseat_at_next_visible_line_start): Use the bidi iterator state
14586 returned by forward_to_next_line_start to restore the state of
14587 it->bidi_it after backing up to previous newline. (Bug#9212)
14589 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14591 * regex.c (re_comp): Protoize.
14592 (re_exec): Fix return type.
14593 (regexec): Fix type of `ret'. (Bug#9203)
14595 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14597 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14598 This is needed if max-image-size is a floating-point number.
14600 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14602 * print.c (print_object): Print empty symbol as ##.
14604 * lread.c (read1): Read ## as empty symbol.
14606 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14608 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14609 setting frame foreground color (Bug#9175).
14610 (x_set_background_color): Likewise.
14612 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14613 contents (Bug#9176).
14614 (EmacsTooltip -init): Remove bezels and add shadows to
14617 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14618 or scroll bar (Bug#8470).
14620 * nsfont.m (nsfont_open): Remove assignment to voffset and
14621 unnecessary vars hshink, expand, hd, full_height, min_height.
14622 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14624 * nsterm.h (nsfont_info): Remove voffset field.
14626 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14628 Implement strike-through and overline on NextStep (Bug#8863).
14630 * nsfont.m (nsfont_open): Use underline position provided by font,
14631 instead of hard-coded value of 2.
14632 (nsfont_draw): Call ns_draw_text_decoration instead.
14634 * nsterm.h: Add declaration for ns_draw_text_decoration.
14636 * nsterm.m (ns_draw_text_decoration): New function for drawing
14637 underline, overline, and strike-through.
14638 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14639 ns_draw_text_decoration. Change treatment of cursor drawing to
14640 accommodate underlining, etc.
14642 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14644 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14647 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14649 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14650 Without this fix, if a signal arrives just after memory fills up,
14651 'malloc' might be invoked reentrantly.
14653 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14654 In other words, assume that every image size is allowed, on non-X
14655 hosts. This assumption is probably wrong, but it lets Emacs compile.
14657 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14659 * regex.c (re_iswctype): Convert return values to boolean.
14661 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14663 * xdisp.c (compute_display_string_pos): Don't use cached display
14664 string position if the buffer had its restriction changed.
14667 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14669 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14671 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14673 Integer signedness and overflow and related fixes. (Bug#9079)
14675 * bidi.c: Integer size and overflow fixes.
14676 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14677 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14678 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14679 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14680 (bidi_find_other_level_edge):
14681 Use ptrdiff_t instead of EMACS_INT where either will do.
14682 This works better on 32-bit hosts configured --with-wide-int.
14683 (bidi_cache_ensure_space): Check for size-calculation overflow.
14684 Use % rather than repeated addition, for better worst-case speed.
14685 Don't set bidi_cache_size until after xrealloc returns, because it
14687 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14688 (bidi_cache_ensure_space): Also check that the bidi cache size
14689 does not exceed that of the largest Lisp string or buffer. See Eli
14690 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14692 * alloc.c (__malloc_size_t): Remove.
14693 All uses replaced by size_t. See Andreas Schwab's note
14694 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14696 * image.c: Improve checking for integer overflow.
14697 (check_image_size): Assume that f is nonnull, since
14698 it is always nonnull in practice. This is one less thing to
14699 worry about when checking for integer overflow later.
14700 (x_check_image_size): New function, which checks for integer
14701 overflow issues inside X.
14702 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14703 This removes the need for a memory_full check.
14704 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14705 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14706 (xbm_read_bitmap_data): Change locals back to 'int', since
14707 their values must fit in 'int'.
14708 (xpm_load_image, png_load, tiff_load):
14709 Invoke x_create_x_image_and_pixmap earlier,
14710 to avoid much needless work if the image is too large.
14711 (tiff_load): Treat overly large images as if
14712 x_create_x_image_and_pixmap failed, not as malloc failures.
14713 (gs_load): Use x_check_image_size.
14715 * gtkutil.c: Omit integer casts.
14716 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14717 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14719 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14721 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14722 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14723 would wrongly return t on a 64-bit host.
14725 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14726 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14727 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14728 and therefore cause GCC to emit a bogus diagnostic in some cases.
14730 * image.c: Integer signedness and overflow and related fixes.
14731 This is not an exhaustive set of fixes, but it's time to
14732 record what I've got.
14733 (lookup_pixel_color, check_image_size): Remove redundant decls.
14734 (check_image_size): Don't assume that arbitrary EMACS_INT values
14735 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14736 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14737 (tiff_load, imagemagick_load_image):
14738 Check for overflow in size calculations.
14739 (x_create_x_image_and_pixmap): Remove unnecessary test for
14740 xmalloc returning NULL; that can't happen.
14741 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14742 (xpm_color_bucket): Use better integer hashing function.
14743 (xpm_cache_color): Don't possibly over-allocate memory.
14744 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14745 (gif_memory_source):
14746 Use ptrdiff_t, not int or size_t, to record sizes.
14747 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14748 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14749 either works, as we prefer signed integers.
14750 (tiff_read_from_memory, tiff_write_from_memory):
14751 Return tsize_t, not size_t, since that's what the TIFF API wants.
14752 (tiff_read_from_memory): Don't fail simply because the read would
14753 go past EOF; instead, return a short read.
14754 (tiff_load): Omit no-longer-needed casts.
14755 (Fimagemagick_types): Don't assume size fits into 'int'.
14757 Improve hashing quality when configured --with-wide-int.
14758 * fns.c (hash_string): New function, taken from sxhash_string.
14759 Do not discard information about ASCII character case; this
14760 discarding is no longer needed.
14761 (sxhash-string): Use it. Change sig to match it. Caller changed.
14762 * lisp.h: Declare it.
14763 * lread.c (hash_string): Remove, since we now use fns.c's version.
14764 The fns.c version returns a wider integer if --with-wide-int is
14765 specified, so this should help the quality of the hashing a bit.
14767 * emacs.c: Integer overflow minor fix.
14768 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14769 Define only if GNU_LINUX.
14770 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14772 * dispnew.c: Integer signedness and overflow fixes.
14773 Remove unnecessary forward decls, that were a maintenance hassle.
14774 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14776 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14777 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14778 (prepare_desired_row, line_draw_cost):
14779 Use int, not unsigned, where either works.
14780 (save_current_matrix, restore_current_matrix):
14781 Use ptrdiff_t, not size_t, where either works.
14782 (init_display): Check for overflow more accurately, and without
14783 relying on undefined behavior.
14785 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14786 Remove, replacing with the new symbols in lisp.h. All uses changed.
14787 * fileio.c (make_temp_name):
14788 * filelock.c (lock_file_1, lock_file):
14789 * xdisp.c (message_dolog):
14790 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14791 Use pMd etc. instead.
14792 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14793 replacing the pWIDE etc. symbols removed from editfns.c.
14795 * keyboard.h (num_input_events): Now uintmax_t.
14796 This is (very slightly) less likely to mess up due to wraparound.
14799 * buffer.c: Integer signedness fixes.
14800 (alloc_buffer_text, enlarge_buffer_text):
14801 Use ptrdiff_t rather than size_t when either will do, as we prefer
14804 * alloc.c: Integer signedness and overflow fixes.
14805 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14806 (__malloc_size_t): Default to size_t, not to int.
14807 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14808 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14809 Prefer ptrdiff_t to size_t when either would do, as we prefer
14811 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14812 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14813 Now const. Initialize with values that are in range even if char
14815 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14816 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14817 These functions do the right thing with sizes > 2**32.
14818 (check_depth): Now ptrdiff_t, not int.
14819 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14820 Adjust to new way of storing sizes. Check for size overflow bugs
14822 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14823 slightly wrong anyway, as it missed one instance of
14824 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14825 (refill_memory_reserve): Omit needless cast to size_t.
14826 (mark_object_loop_halt): Mark as externally visible.
14828 * xselect.c: Integer signedness and overflow fixes.
14829 (Fx_register_dnd_atom, x_handle_dnd_message):
14830 Use ptrdiff_t, not size_t, since we prefer signed.
14831 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14832 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14833 x_dnd_atoms_size and x_dnd_atoms_length.
14835 * doprnt.c: Prefer signed to unsigned when either works.
14837 * doprnt.c (doprnt):
14839 * xdisp.c (vmessage):
14840 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14841 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14842 prefer signed arithmetic to avoid comparison confusion.
14843 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14844 but is a bit tricky.
14846 Assume freestanding C89 headers, string.h, stdlib.h.
14847 * data.c, doprnt.c, floatfns.c, print.c:
14848 Include float.h unconditionally.
14849 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14850 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14851 * regex.c: Likewise for stddef.h, string.h.
14852 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14853 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14854 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14855 (STDC_HEADERS): Remove obsolete defines.
14856 * sysdep.c: Include limits.h unconditionally.
14858 Assume support for memcmp, memcpy, memmove, memset.
14859 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14860 * regex.c (memcmp, memcpy):
14861 Remove; we assume C89 now.
14863 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14864 (__malloc_safe_bcopy): Remove; no longer needed.
14866 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14867 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14868 well either way, and we prefer signed to unsigned.
14870 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14872 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14873 closes the connection while we're reading (bug#9182).
14875 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14877 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14878 are specified (Bug#9168).
14880 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14882 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14883 Found by GCC static checking and --with-wide-int on a 32-bit host.
14885 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14887 * xdisp.c (compute_display_string_pos): Fix logic of caching
14888 previous display string position. Initialize cached_prev_pos to
14889 -1. Fixes slow-down at the beginning of a buffer.
14891 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14893 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14894 for attrs[LFACE_FONTSET_INDEX].
14896 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14898 * xml.c (parse_region): Remove unused local
14899 that was recently introduced.
14901 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14903 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14904 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14906 * xdisp.c (move_it_in_display_line_to): Record the best matching
14907 position for TO_CHARPOS while scanning the line, and restore it on
14908 exit if none of the characters scanned was an exact match.
14909 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14910 when exact match is impossible due to invisible text, and the
14911 lines are truncated.
14913 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14915 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14918 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14920 Fix a significant slow-down of cursor motion with C-n, C-p,
14921 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14922 auto-repeat under bidi redisplay in fontified buffers.
14923 * xdisp.c (compute_stop_pos_backwards): New function.
14924 (next_element_from_buffer): Call compute_stop_pos_backwards to
14925 find a suitable prev_stop when we find ourselves before
14927 (reseat): Don't look for prev_stop, as that could mean a very long
14929 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14930 <cached_disp_overlay_modiff>: Cache for last found display string
14932 (compute_display_string_pos): Return the cached position if asked
14933 about the same buffer in the same area of character positions, and
14934 the buffer wasn't changed since the time the display string
14935 position was cached.
14937 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14939 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14940 is an integer, which is important for empty lines. (Bug#9149)
14942 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14944 * frame.c (Fmodify_frame_parameters): In tty case, update the
14945 default face if necessary (Bug#4238).
14947 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14949 * editfns.c (Fstring_to_char): No need to explain what a character
14950 is in the docstring (Bug#6576).
14952 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14954 * xml.c (parse_region): Make sure we always return a tree.
14956 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14958 * xml.c (parse_region): If a document contains only comments,
14961 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14963 * xml.c (make_dom): Return comments, too.
14965 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14968 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14969 and the surrounding thread.
14970 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14971 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14972 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14974 * s/openbsd.h (BROKEN_SIGIO): Define.
14975 * unexelf.c (unexec) [__OpenBSD__]:
14976 Don't update the .mdebug section of the Alpha COFF symbol table.
14978 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14980 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14983 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14985 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14986 This fixes some race conditions on the permissions of any newly
14989 * alloc.c (valid_pointer_p): Use pipe, not open.
14990 This fixes some permissions issues when debugging.
14992 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14993 If fchown fails to set both uid and gid, try to set just gid,
14994 as that is sometimes allowed. Adjust the file's mode to eliminate
14995 setuid or setgid bits that are inappropriate if fchown fails.
14997 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14999 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15000 to compare Lisp_Objects.
15001 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15002 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15003 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15005 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15007 * lread.c (read_integer): Unread even EOF character.
15008 (read1): Likewise. Properly record start position of symbol.
15010 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15011 symbol character follows.
15013 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15015 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15016 This works around a problem with the previous change to Fcopy_file.
15017 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15018 and without this change, GCC might complain about discarding
15019 fchown's return value.
15021 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15023 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15025 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15027 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15029 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15031 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15032 it's used from the C level.
15034 * process.c: Use the same condition for POLL_FOR_INPUT in both
15035 keyboard.c and process.c (bug#1858).
15037 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15039 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15040 (Fgnutls_boot): Use it.
15042 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15044 * doc.c (Fsubstitute_command_keys): Revert last change.
15046 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15048 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15049 quotes the next character, and doesn't affect other longer
15050 sequences (bug#8935).
15052 * lread.c (syms_of_lread): Clarify that is isn't only
15053 `eval-buffer' and `eval-defun' that's affected by
15054 `lexical-binding' (bug#8460).
15056 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15058 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15059 bidi redisplay when a line includes both an image and is truncated.
15061 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15063 Fix minor problems found by static checking.
15064 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15065 (elsz): Now a signed constant, not a size_t var. We prefer signed
15066 types to unsigned, to avoid integer comparison confusion. Without
15067 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15068 "cannot optimize loop, the loop counter may overflow", a symptom
15070 * indent.c (Fvertical_motion): Mark locals as initialized.
15071 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15073 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15075 * search.c (Fre_search_backward): Mention `case-fold-search' in
15076 all the re_search_* functions (bug#8138).
15078 * keyboard.c (Fopen_dribble_file): Document when the file is

15083 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15086 Support bidi reordering of display and overlay strings.

15088 (compute_display_string_end): Accept additional argument STRING.
15089 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15090 (reseat_to_string): Initialize bidi_it->string.s and
15091 bidi_it->string.schars.
15092 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15093 NULL (avoids a crash in bidi_paragraph_init).
15094 Initialize itb.string.lstring.
15095 (init_iterator): Call bidi_init_it only of a valid
15096 buffer position was specified. Initialize paragraph_embedding to
15098 (reseat_to_string): Initialize the bidi iterator.
15099 (display_string): If we need to ignore text properties of
15100 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15101 original value of -1 will not work with bidi.)
15102 (compute_display_string_pos): First arg is now struct
15103 `text_pos *'; all callers changed. Support display properties on
15105 (compute_display_string_end): Support display properties on Lisp
15107 (init_iterator, reseat_1, reseat_to_string): Initialize the
15108 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15109 when iterating on a string not from display properties).
15110 (compute_display_string_pos, compute_display_string_end):
15111 Fix calculation of the object to scan. Fixes an error when using
15113 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15114 base_level_stop; instead, set base_level_stop to BEGV.
15115 Fixes crashes in vertical-motion.
15116 (next_element_from_buffer): Improve commentary for when
15117 the iterator is before prev_stop.
15118 (init_iterator): Initialize bidi_p from the default value of
15119 bidi-display-reordering, not from buffer-local value. Use the
15120 buffer-local value only if initializing for buffer iteration.
15121 (handle_invisible_prop): Support invisible properties on strings
15122 that are being bidi-reordered.
15123 (set_iterator_to_next): Support bidi reordering of C strings and
15125 (next_element_from_string): Support bidi reordering of Lisp
15127 (handle_stop_backwards): Support Lisp strings as well.
15128 (display_string): Support display of R2L glyph rows.
15129 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15130 (init_iterator): Don't initialize it->bidi_p for strings
15132 (reseat_to_string): Initialize it->bidi_p for strings here.
15133 (next_element_from_string, next_element_from_c_string)
15134 (next_element_from_buffer): Add xassert's for correspondence
15135 between IT's object being iterated and it->bidi_it.string
15137 (face_before_or_after_it_pos): Support bidi iteration.
15138 (next_element_from_c_string): Handle the case of the first string
15139 character that is not the first one in the visual order.
15140 (get_visually_first_element): New function, refactored from common
15141 parts of next_element_from_buffer, next_element_from_string, and
15142 next_element_from_c_string.
15143 (tool_bar_lines_needed, redisplay_tool_bar)
15144 (display_menu_bar): Force left-to-right direction. Add a FIXME
15145 comment for making that be controlled by a user option.
15146 (push_it, pop_it): Save and restore the state of the
15147 bidi iterator. Save and restore the bidi_p flag.
15148 (pop_it): Iterate out of display property for string iteration as
15150 (iterate_out_of_display_property): Support iteration over strings.
15151 (handle_single_display_spec): Set up it->bidi_it for iteration
15152 over a display string, and call bidi_init_it.
15153 (handle_single_display_spec, next_overlay_string)
15154 (get_overlay_strings_1, push_display_prop): Set up the bidi
15155 iterator for displaying display or overlay strings.
15156 (forward_to_next_line_start): Don't use the shortcut if
15158 (back_to_previous_visible_line_start): If handle_display_prop
15159 pushed the iterator stack, restore the internal state of the bidi
15160 iterator by calling bidi_pop_it same number of times.
15161 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15162 and we are bidi-iterating, don't decrement the iterator position;
15163 instead, set the first_elt flag in the bidi iterator, to produce
15165 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15166 (push_display_prop): xassert that we are iterating a buffer.
15167 (push_it, pop_it): Save and restore paragraph_embedding member.
15168 (handle_single_display_spec, next_overlay_string)
15169 (get_overlay_strings_1, reseat_1, reseat_to_string)
15170 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15171 correctly. Don't assume unibyte strings are not bidi-reordered.
15172 (compute_display_string_pos)
15173 (compute_display_string_end): Fix handling the case of C string.
15174 (push_it, pop_it): Save and restore from_disp_prop_p.
15175 (handle_single_display_spec, push_display_prop): Set the
15176 from_disp_prop_p flag.
15177 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
15178 (pop_it): Call iterate_out_of_display_property only if we are
15179 popping after iteration over a string that came from a display
15180 property. Fix a typo in popping stretch info. Add an assertion
15181 for verifying that the iterator position is in sync with the bidi
15183 (handle_single_display_spec, get_overlay_strings_1)
15184 (push_display_prop): Fix initialization of paragraph direction for
15185 string when that of the parent object is not yet determined.
15186 (reseat_1): Call bidi_init_it to resync the bidi
15187 iterator with IT's position. (Bug#7616)
15188 (find_row_edges): If ROW->start.pos gives position
15189 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

15634 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
15636 Random fixes. E.g., (random) never returned negative values.
15637 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15638 subseconds part to the entropy, as that's a bit more random.
15639 Prefer signed to unsigned, since the signedness doesn't matter and
15640 in general we prefer signed. When given a limit, use a
15641 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15642 latter isn't right if USE_2_TAGS_FOR_INTS.
15643 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15644 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15646 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15648 * textprop.c (text_property_stickiness):
15649 Obey Vtext_property_default_nonsticky.

15657 This is more efficient than Ffile_directory_p and avoids a minor race.
15659 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15661 * buffer.c (Foverlay_put): Say what the return value is
15664 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15665 is a directory before asking whether to use the file name
15667 (barf_or_query_if_file_exists): Make the "File is a directory"
15668 error be more correct.
15670 * fns.c (Frequire): Remove the mention of the .gz files, since
15671 that's installation-specific, but keep the mention of
15672 `get-load-suffixes'.
15674 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15676 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15681 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
15682 (syms_of_gnutls): Remove duplicate DEFSYM for
15683 Qgnutls_bootprop_verify_hostname_error, an error for
15684 Qgnutls_bootprop_verify_error (which is no longer used).
15686 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15687 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15688 Also (re)move comments that are misplaced or no longer relevant.
15690 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15692 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15720 * fns.c (Frequire): Mention .el.gz files (bug#7314).
15721 (Frequire): Mention get-load-suffixes.
15723 2011-07-02 Martin Rudalics <rudalics@gmx.at>

15789 * eval.c (struct backtrace): Simplify and port the data structure.
15790 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15791 signed bit field, as this assumption is not portable and it makes
15792 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15793 "char debug_on_exit : 1" as this is not portable either; instead,
15794 use the portable "unsigned int debug_on_exit : 1". Remove unused
15795 member evalargs. Remove obsolete comments about cc bombing out.
15797 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

15865 (emacs_fixed_new): Set priv->f to argument.
15866 (emacs_fixed_get_preferred_width)
15867 (emacs_fixed_get_preferred_height): Use min_width/height from
15868 frames size_hint to set minimum and natural (Bug#8919).
15869 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15870 and use min_width/height from frames size_hint to set
15871 min_width/height (Bug#8919).

15963 * print.c (printchar, strout): Check for string overflow.
15964 (PRINTPREPARE, printchar, strout):
15965 Don't set size unless allocation succeeds.
15967 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15968 for sizes. Check for string overflow more accurately.

15982 (read_integer): Radix is now EMACS_INT, not int,
15983 to improve quality of diagnostics for out-of-range radices.
15984 Calculate buffer size correctly for out-of-range radices.
15985 (read1): Check for integer overflow in radices, and in
15986 read-circle numbers.
15987 (read_escape): Avoid int overflow.
15988 (Fload, openp, read_buffer_size, read1)
15989 (substitute_object_recurse, read_vector, read_list, map_obarray):
15990 Use ptrdiff_t, not int, for sizes.

16012 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16013 The following patches are for when GLYPH_DEBUG && !XASSERT.
16014 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16015 * dispnew.c (flush_stdout):
16016 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16017 Mark as externally visible.
16018 * dispnew.c (check_window_matrix_pointers): Now static.
16019 * dispnew.c (window_to_frame_vpos):
16020 * xfns.c (unwind_create_frame):

16027 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16029 (debug_method_add): Use va_list and vsprintf rather than relying
16030 on undefined behavior with wrong number of arguments.
16031 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16032 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16033 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16034 since we're not interested in debugging glyphs with old libraries.
16035 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16036 GCC 4.6.0's static checking.
16038 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

16067 * xfaces.c (face_at_buffer_position):
16068 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16069 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16070 (Fnext_overlay_change, Fprevious_overlay_change)
16071 (mouse_face_overlay_overlaps, Foverlays_in):
16072 Use ptrdiff_t, not int, for sizes.
16073 (overlays_at, overlays_in): Check for size-calculation overflow.
16075 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16077 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16078 (x_session_initialize): Do not assume string length fits in int.
16080 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16081 This is unlikely, but can occur if DPI is outlandish.
16083 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16084 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16086 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16087 * xrdb.c (magic_file_p, search_magic_path):
16088 Omit last arg SUFFIX; it was always 0. All callers changed.
16089 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16091 * xfont.c (xfont_match): Avoid need for strlen.
16093 * xfns.c: Don't assume strlen fits in int.
16094 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16096 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16097 not unsigned long, as we prefer signed integers. All callers changed.
16098 Detect integer overflow in repeat count.
16099 (message_dolog): Don't assume print length fits in 39 bytes.
16100 (display_mode_element): Don't assume strlen fits in int.
16102 * termcap.c: Don't assume sizes fit in int and never overflow.
16103 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16104 (gobble_line): Check for size-calculation overflow.
16106 * minibuf.c (Fread_buffer):
16107 * lread.c (intern, intern_c_string):
16108 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16109 Don't assume string length fits in int.
16111 * keyboard.c (parse_tool_bar_item):
16112 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16114 * font.c: Don't assume string length fits in int.
16115 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16116 Use ptrdiff_t, not int.
16117 (font_intern_prop): Don't assume string length fits in int.
16118 Don't assume integer property fits in fixnum.
16119 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16121 * filelock.c: Fix some buffer overrun and integer overflow issues.
16122 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16123 Reformulate so as not to need the command string.
16124 Invoke gzip -cd rather than gunzip, as it's more portable.
16125 (lock_info_type, lock_file_1, lock_file):
16126 Don't assume pid_t and time_t fit in unsigned long.
16127 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16128 (current_lock_owner): Prefer signed type for sizes.
16129 Use memcpy, not strncpy, where memcpy is what is really wanted.
16130 Don't assume (via atoi) that time_t and pid_t fit in int.
16131 Check for time_t and/or pid_t out of range, e.g., via a network share.
16132 Don't alloca where an auto var works fine.
16134 * fileio.c: Fix some integer overflow issues.
16135 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16136 Don't assume string length fits in int.
16137 (directory_file_name): Don't assume string length fits in long.
16138 (make_temp_name): Don't assume pid fits in int, or that its print
16139 length is less than 20.
16141 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16143 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16145 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16147 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16148 We prefer signed integers, even for size calculations.
16150 * emacs.c: Don't assume string length fits in 'int'.
16151 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16152 (main): Don't invoke strlen when not needed.
16154 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16155 (XD_DEBUG_MESSAGE): Don't waste a byte.
16157 * callproc.c (getenv_internal_1, getenv_internal)
16158 (Fgetenv_internal):
16159 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16161 * lread.c (invalid_syntax): Omit length argument.
16162 All uses changed. This doesn't fix a bug, but it simplifies the
16163 code away from its former Hollerith-constant appearance, and it's
16164 one less 'int' to worry about when looking at integer-overflow issues.
16165 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16167 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16168 This didn't break anything, but it didn't help either.
16169 It's confusing to put a bogus integer in a place where the actual
16170 value does not matter.
16171 (LIST_END_P): Remove unused macro and its bogus comment.
16172 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16174 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16175 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16177 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16178 We prefer signed types, and the value cannot exceed the EMACS_INT
16179 range anyway (because otherwise the length would not be representable).
16180 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16181 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16182 This avoids a GCC warning when WIDE_EMACS_INT.
16184 * indent.c (sane_tab_width): New function.
16185 (current_column, scan_for_column, Findent_to, position_indentation)
16186 (compute_motion): Use it. This is just for clarity.
16187 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16189 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16191 * lisp.h (lint_assume): New macro.
16192 * composite.c (composition_gstring_put_cache):
16193 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16195 * editfns.c, insdel.c:
16196 Omit unnecessary forward decls, to simplify future changes.
16198 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16200 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16202 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16203 Use much-faster test for byte-length change.
16204 Don't assume string byte-length fits in 'int'.
16205 Check that character arg fits in 'int'.
16206 (mapcar1): Declare byte as byte, for clarity.
16208 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16210 * fns.c (concat): Catch string overflow earlier.
16211 Do not rely on integer wraparound.
16213 * dispextern.h (struct it.overlay_strings_charpos)
16214 (struct it.selective): Now EMACS_INT, not int.
16215 * xdisp.c (forward_to_next_line_start)
16216 (back_to_previous_visible_line_start)
16217 (reseat_at_next_visible_line_start, next_element_from_buffer):
16218 Don't arbitrarily truncate the value of 'selective' to int.
16220 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16222 * composite.c: Don't truncate sizes to 'int'.
16223 (composition_gstring_p, composition_reseat_it)
16224 (composition_adjust_point): Use EMACS_INT, not int.
16225 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16226 not EMACS_UINT, for indexes.
16228 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16230 * buffer.c: Include <verify.h>.
16231 (struct sortvec.priority, struct sortstr.priority):
16232 Now EMACS_INT, not int.
16233 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16234 (struct sortstr.size, record_overlay_string)
16235 (struct sortstrlist.size, struct sortlist.used):
16236 Don't truncate size to int.
16237 (record_overlay_string): Check for size-calculation overflow.
16238 (init_buffer_once): Check at compile-time, not run-time.
16240 2011-06-22 Jim Meyering <meyering@redhat.com>
16242 Don't leak an XBM-image-sized buffer
16243 * image.c (xbm_load): Free the image buffer after using it.
16245 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16248 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16249 that Sun C diagnosed.
16250 * fns.c (secure_hash): Fix pointer signedness issue.
16251 * intervals.c (static_offset_intervals): New function.
16252 (offset_intervals): Use it.
16254 2011-06-21 Leo Liu <sdl.web@gmail.com>
16257 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16260 * fns.c (secure_hash): Rename from crypto_hash_function and change
16261 the first arg to accept symbols.
16262 (Fsecure_hash): New primitive.
16263 (syms_of_fns): New symbols.
16265 2011-06-20 Deniz Dogan <deniz@dogan.se>
16267 * process.c (Fset_process_buffer): Clarify return value in
16270 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16272 * dispnew.c (add_window_display_history): Use BVAR.
16274 * xdisp.c (debug_method_add): Use BVAR.
16275 (check_window_end, dump_glyph_matrix, dump_glyph)
16276 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16278 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16281 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16282 check till after the cache is created in init_frame_faces.
16284 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16286 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16288 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16290 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16291 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16292 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16294 Improve buffer-overflow checking (Bug#8873).
16295 * fileio.c (Finsert_file_contents):
16296 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16297 Remove the old (too-loose) buffer overflow checks.
16298 They weren't needed, since make_gap checks for buffer overflow.
16299 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16300 The old code merely checked for Emacs fixnum overflow, and relied
16301 on undefined (wraparound) behavior. The new code avoids undefined
16302 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16304 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16305 Tune. Don't use wider integers than needed. Don't use alloca.
16306 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16308 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16310 * insdel.c, lisp.h (buffer_overflow): New function.
16311 (insert_from_buffer_1, replace_range, replace_range_2):
16312 * insdel.c (make_gap_larger):
16313 * editfns.c (Finsert_char):
16314 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16316 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16318 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16320 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16322 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16323 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16325 * fileio.c: Don't assume EMACS_INT fits in off_t.
16326 (emacs_lseek): New static function.
16327 (Finsert_file_contents, Fwrite_region): Use it.
16328 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16330 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16332 * fns.c: Don't overflow int when computing a list length.
16333 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16334 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16335 truncation on 64-bit hosts. Check for QUIT every
16336 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16337 faster and is responsive enough.
16338 (Flength): Report an error instead of overflowing an integer.
16339 (Fsafe_length): Return a float if the value is not representable
16340 as a fixnum. This shouldn't happen except in contrived situations.
16341 (Fnthcdr, Fsort): Don't assume list length fits in int.
16342 (Fcopy_sequence): Don't assume vector length fits in int.
16344 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16345 (header_size, word_size): New constants.
16346 (allocate_vectorlike): Don't check size overflow here.
16347 (allocate_vector): Check it here instead, since this is the only
16348 caller of allocate_vectorlike that could cause overflow.
16349 Check that the new vector's length is representable as a fixnum.
16351 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16352 The previous code was bogus. For example, next_almost_prime (32)
16353 returned 39, which is undesirable as it is a multiple of 3; and
16354 next_almost_prime (24) returned 25, which is a multiple of 5 so
16355 why was the code bothering to check for multiples of 7?
16357 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16359 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16361 Variadic C functions now count arguments with ptrdiff_t.
16362 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16363 Back then I didn't know that the Emacs coding style prefers signed int.
16364 Also, in the meantime I found a few more instances where arguments
16365 were being counted with int, which may truncate counts on 64-bit
16366 machines, or EMACS_INT, which may be unnecessarily wide.
16367 * lisp.h (struct Lisp_Subr.function.aMANY)
16368 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16369 Arg counts are now ptrdiff_t, not size_t.
16370 All variadic functions and their callers changed accordingly.
16371 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16372 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16373 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16374 * callint.c (Fcall_interactively): Check arg count for overflow,
16375 to avoid potential buffer overrun. Use signed char, not 'int',
16376 for 'varies' array, so that we needn't bother to check its size
16377 calculation for overflow.
16378 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16379 * eval.c (apply_lambda):
16380 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16381 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16382 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16384 * callint.c (Fcall_interactively): Don't use index var as event count.
16386 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16387 * mem-limits.h (SIZE): Remove; no longer used.
16389 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16391 Remove unnecessary casts.
16392 * xterm.c (x_term_init):
16393 * xfns.c (x_set_border_pixel):
16394 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16395 These aren't needed now that we assume ANSI C.
16397 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16398 It's more likely to cause problems (due to unsigned overflow)
16401 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16403 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16405 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16407 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16409 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16411 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16413 GLYPH_CODE_FACE returns EMACS_INT, not int.
16414 * dispextern.h (merge_faces):
16415 * xfaces.c (merge_faces):
16416 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16417 Don't assume EMACS_INT fits in int.
16419 * character.h (CHAR_VALID_P): Remove unused parameter.
16420 * fontset.c, lisp.h, xdisp.c: All uses changed.
16422 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16424 * fns.c (concat): Minor tuning based on overflow analysis.
16425 This doesn't fix any bugs. Use int to hold character, instead
16426 of constantly refetching from Emacs object. Use XFASTINT, not
16427 XINT, for value known to be a character. Don't bother comparing
16428 a single byte to 0400, as it's always less.
16430 * floatfns.c (Fexpt):
16431 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16433 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16436 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16438 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16439 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16440 incorrectly succeed when S was a string, because 4294967386 was
16441 truncated before it was used.
16443 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16444 Otherwise, an out-of-range integer could cause undefined behavior
16447 * composite.c: Use int, not EMACS_INT, for characters.
16448 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16449 EMACS_INT, for values that are known to be in character range.
16450 This doesn't fix any bugs but is the usual style inside Emacs and
16451 may generate better code on 32-bit machines.
16453 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16454 This is for reasons similar to the recent CHAR_STRING fix.
16455 * charset.c (Fencode_char): Check that character arg is actually
16456 a character. Pass an int to ENCODE_CHAR.
16457 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16458 wider than 'int', as a compile-time check to prevent future regressions
16461 * character.c (char_string): Remove unnecessary casts.
16463 Make sure a 64-bit char is never passed to CHAR_STRING.
16464 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16465 by silently ignoring the top 32 bits, allowing some values
16466 that were far too large to be valid characters.
16467 * character.h: Include <verify.h>.
16468 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16469 arguments are no wider than unsigned, as a compile-time check
16470 to prevent future regressions in this area.
16472 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16473 (Fsubst_char_in_region):
16475 * xdisp.c (decode_mode_spec_coding):
16476 Adjust to CHAR_STRING's new requirement.
16477 * editfns.c (Finsert_char, Fsubst_char_in_region):
16478 * fns.c (concat): Check that character args are actually
16479 characters. Without this test, these functions did the wrong
16480 thing with wildly out-of-range values on 64-bit hosts.
16482 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16483 These casts should not be needed on 32-bit hosts, either.
16484 * keyboard.c (read_char):
16485 * lread.c (Fload): Remove casts to unsigned.
16487 * lisp.h (UNSIGNED_CMP): New macro.
16488 This fixes comparison bugs on 64-bit hosts.
16489 (ASCII_CHAR_P): Use it.
16490 * casefiddle.c (casify_object):
16491 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16492 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16493 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16494 * dispextern.h (FACE_FROM_ID):
16495 * keyboard.c (read_char): Use UNSIGNED_CMP.
16497 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16498 not to EMACS_INT, to avoid GCC warning.
16500 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16502 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16503 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16504 isn't needed on 32-bit machines.
16506 * buffer.c (Fgenerate_new_buffer_name):
16507 Use EMACS_INT for count, not int.
16508 (advance_to_char_boundary): Return EMACS_INT, not int.

17139 instead of using explicit *_CHAR codes.
17140 (bidi_resolve_explicit, bidi_resolve_weak):

17149 (bidi_level_of_next_char): Don't try to lookup the cache for the
17150 next/previous character if nothing is cached there yet, or if we
17151 were just reseat()'ed to a new position.
17153 * xdisp.c (set_cursor_from_row): Set start and stop points
17154 according to the row's direction when priming the loop that looks
17155 for the glyph on which to display cursor.

17157 (display_prop_intangible_p): Reimplement to call
17158 handle_display_spec instead of single_display_spec_intangible_p.
17159 Accept 3 additional arguments needed by handle_display_spec.
17160 This fixes incorrect cursor motion across display property with complex
17161 values: lists, `(when COND...)' forms, etc.

17163 lists with the argument STRING its top-level element.
17164 (display_prop_string_p): Fix the condition for processing a

17168 (compute_display_string_pos): Accept additional argument
17169 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17170 value of a `display' property is a "replacing spec".
17171 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17172 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17173 the display property, but just return a value indicating whether
17174 the display property will replace the characters it covers.
17175 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17176 frame_window_p members of struct bidi_it.
17177 (compute_display_string_pos, compute_display_string_end):

17200 All callers changed. (Bug#8762)
17202 * gnutls.c: Use Emacs's memory allocators.
17203 Without this change, the gnutls library would invoke malloc etc.
17204 directly, which causes problems on non-SYNC_INPUT hosts, and which
17205 runs afoul of improving memory_full behavior. (Bug#8761)
17206 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17207 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17208 xfree instead of the default malloc, realloc, free.
17209 (Fgnutls_boot): No need to check for memory allocation failure,
17210 since xmalloc does that for us.
17212 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

17232 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17233 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17234 * alloc.c (allocate_vectorlike):
17235 Check for overflow in vector size calculations.
17236 * ccl.c (ccl_driver):
17237 Check for overflow when converting EMACS_INT to int.

17239 need to be updated by these changes.
17240 * fns.c (make_hash_table, maybe_resize_hash_table):
17241 Check for integer overflow with large hash tables.
17242 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17243 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17244 (SXHASH_REDUCE): New macro.
17245 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17246 Use it instead of discarding useful hash info with large hash values.
17247 (sxhash_float): New function.
17248 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17249 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17250 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17251 Rewrite to use FIXNUM_BITS, as this simplifies things.
17252 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17253 Adjust signatures to match updated version of code.
17254 (consing_since_gc): Now EMACS_INT, since a single hash table can
17255 use more than INT_MAX bytes.

17304 Make it possible to run ./temacs.
17306 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17307 syms_of_callproc does the same thing. Remove test for

17368 * fns.c (to_uchar): Define.
17369 (crypto_hash_function): Use it to convert some newly-signed

17381 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17382 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17383 to hold a serial number that is too large for a fixnum.
17384 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17385 Check for serial numbers out of range. Decode any serial number
17386 that was so large that it became a float. (Bug#8722)
17388 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17389 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17390 Use XFASTINT rather than XUINT when numbers are nonnegative.
17391 (xd_append_arg, Fdbus_method_return_internal):
17392 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17393 arguments, check that Lisp number is nonnegative, rather than
17394 silently wrapping negative numbers around. (Bug#8722)
17395 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17398 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17400 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17402 ccl: Add integer overflow checks.
17403 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17404 (IN_INT_RANGE): New macros.
17405 (ccl_driver): Use them to check for integer overflow when
17406 decoding a CCL program. Many of the new checks are whether XINT (x)
17407 fits in int; it doesn't always, on 64-bit hosts. The new version
17408 doesn't catch all possible integer overflows, but it's an
17409 improvement. (Bug#8719)
17411 * alloc.c (make_event_array): Use XINT, not XUINT.
17412 There's no need for unsigned here.
17414 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17415 This follows up to the 2011-05-06 change that substituted uintptr_t
17416 for EMACS_INT. This case wasn't caught back then.
17418 Rework Fformat to avoid integer overflow issues.
17419 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17420 now (part of C89). Include <verify.h>.
17421 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17422 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17423 (Fformat): Avoid the prepass trying to compute sizes; it was only
17424 approximate and thus did not catch overflow reliably. Instead, walk
17425 through the format just once, formatting and computing sizes as we go,
17426 checking for integer overflow at every step, and allocating a larger
17427 buffer as needed. Keep track separately whether the format is
17428 multibyte. Keep only the most-recently calculated precision, rather
17429 than them all. Record whether each argument has been converted to
17430 string. Use EMACS_INT, not int, for byte and char and arg counts.
17431 Support field widths and precisions larger than INT_MAX. Avoid
17432 sprintf's undefined behavior with conversion specifications such as %#d
17433 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17434 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17435 formatting out-of-range floating point numbers with int
17436 formats. (Bug#8668)
17438 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17440 * data.c: Avoid integer truncation in expressions involving floats.
17441 * data.c: Include <intprops.h>.
17442 (arith_driver): When there's an integer overflow in an expression
17443 involving floating point, convert the integers to floating point
17444 so that the resulting value does not suffer from catastrophic
17445 integer truncation. For example, on a 64-bit host (* 4
17446 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17447 Do not rely on undefined behavior after integer overflow.
17449 merge count_size_as_multibyte, parse_str_to_multibyte
17450 * character.c, character.h (count_size_as_multibyte):
17451 Rename from parse_str_to_multibyte; all uses changed.
17452 Check for integer overflow.
17453 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17454 since it's now a duplicate of the other. This is more of
17455 a character than a buffer op, so better that it's in character.c.
17456 * fns.c, print.c: Adjust to above changes.
17458 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17460 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17462 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17464 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17465 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17466 (x_clipboard_manager_save): Now static.
17467 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17469 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17470 (crypto_hash_function): Now static.
17471 Fix pointer signedness problems. Avoid unnecessary initializations.
17473 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17475 * termhooks.h (Vselection_alist): Make it terminal-local.
17477 * terminal.c (create_terminal): Initialize it.
17479 * xselect.c: Support for clipboard managers.
17480 (Vselection_alist): Move to termhooks.h as terminal-local var.
17481 (LOCAL_SELECTION): New macro.
17482 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17483 (symbol_to_x_atom): Remove gratuitous arg.
17484 (x_handle_selection_request, lisp_data_to_selection_data)
17485 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17486 (x_own_selection, x_get_local_selection, x_convert_selection):
17487 New arg, specifying work frame. Use terminal-local Vselection_alist.
17488 (some_frame_on_display): Delete unused function.
17489 (Fx_own_selection_internal, Fx_get_selection_internal)
17490 (Fx_disown_selection_internal, Fx_selection_owner_p)
17491 (Fx_selection_exists_p): New optional frame arg.
17492 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17493 (x_handle_selection_clear): Don't treat other terminals with the
17494 same keyboard specially. Use the terminal-local Vselection_alist.
17495 (x_clear_frame_selections): Use Frun_hook_with_args.
17497 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17499 * xterm.h: Add support for those atoms.
17501 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17503 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17504 (converted_selections, conversion_fail_tag): New global variables.
17505 (x_selection_request_lisp_error): Free the above.
17506 (x_get_local_selection): Remove unnecessary code.
17507 (x_reply_selection_request): Args changed; handle arbitrary array
17508 of converted selections stored in converted_selections.
17509 Separate the XChangeProperty and SelectionNotify steps.
17510 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17511 (x_convert_selection): New function.
17512 (x_handle_selection_event): Simplify.
17513 (x_get_foreign_selection): Don't ignore incoming requests while
17514 waiting for an answer; this will fail when we implement
17515 SAVE_TARGETS, and seems unnecessary anyway.
17516 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17517 (Vx_sent_selection_functions): Doc fix.
17519 2011-05-26 Leo Liu <sdl.web@gmail.com>
17521 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17523 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17525 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17527 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17528 for fringe update if it has periodic bitmap.
17529 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17530 and fringe_bitmap_periodic_p.
17532 * fringe.c (get_fringe_bitmap_data): New function.
17533 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17534 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17535 row. Mark glyph row for fringe update if periodicity changed.
17537 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17538 for fringe update unless it has periodic bitmap.
17540 2011-05-25 Kenichi Handa <handa@m17n.org>
17542 * xdisp.c (get_next_display_element): Set correct it->face_id for
17543 a static composition.
17545 2011-05-24 Leo Liu <sdl.web@gmail.com>
17548 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17550 * fns.c (crypto_hash_function, Fsha1): New function.
17551 (Fmd5): Use crypto_hash_function.
17552 (syms_of_fns): Add Ssha1.
17554 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17556 * gnutls.c: Remove unused macros.
17557 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17558 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17559 Remove macros that are defined and never used.
17560 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17562 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17564 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17565 (Fx_get_selection_internal): Minor cleanup.
17566 (Fx_own_selection_internal): Rename arguments for consistency with
17569 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17571 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17573 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17575 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17577 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17579 * dispnew.c (scrolling_window): Don't exclude the case that the
17580 last enabled row in the desired matrix touches the bottom boundary.
17582 2011-05-21 Glenn Morris <rgm@gnu.org>
17584 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17585 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17586 and add some more files.
17588 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17590 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17591 report_file_error introduced by the change from 2011-05-07.
17593 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17595 * systime.h (Time): Define only if emacs is defined.
17596 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17597 where the include path doesn't have X11/X.h by default. See
17598 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17600 2011-05-20 Kenichi Handa <handa@m17n.org>
17602 * composite.c (find_automatic_composition): Fix previous change.
17604 2011-05-20 Glenn Morris <rgm@gnu.org>
17606 * lisp.mk: New file, split from Makefile.in.
17607 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17608 (shortlisp): Remove.
17609 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17611 2011-05-19 Glenn Morris <rgm@gnu.org>
17613 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17614 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17615 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17616 (lisp): Set the order to that of loadup.el.
17617 (shortlisp): Make it a copy of $lisp.
17618 (SOME_MACHINE_LISP): Remove.
17619 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17620 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17622 2011-05-18 Kenichi Handa <handa@m17n.org>
17624 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17625 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17626 (find_automatic_composition): Mostly rewrite for efficiency.
17628 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17630 * makefile.w32-in: Update dependencies.
17632 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17634 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17635 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17637 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17639 Fix some integer overflow issues, such as string length overflow.
17641 * insdel.c (count_size_as_multibyte): Check for string overflow.
17643 * character.c (lisp_string_width): Check for string overflow.
17644 Use EMACS_INT, not int, for string indexes and lengths; in
17645 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17646 the resulting string length overflows an EMACS_INT; instead,
17647 report a string overflow if no precision given. When checking for
17648 precision exhaustion, use a check that cannot possibly have
17649 integer overflow. (Bug#8675)
17650 * character.h (lisp_string_width): Adjust to new signature.
17652 * alloc.c (string_overflow): New function.
17653 (Fmake_string): Use it. This doesn't change behavior, but saves
17654 a few bytes and will simplify future changes.
17655 * character.c (string_escape_byte8): Likewise.
17656 * lisp.h (string_overflow): New decl.
17658 Fixups, following up to the user-interface timestamp change.
17659 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17660 for UI timestamps, instead of unsigned long.
17661 * msdos.c (mouse_get_pos): Likewise.
17662 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17663 * w32gui.h (Time): Define by including "systime.h" rather than by
17664 declaring it ourselves. (Bug#8664)
17666 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17667 * image.c (clear_image_cache): Likewise.
17669 * term.c (term_mouse_position): Don't assume time_t wraparound.
17671 Be more systematic about user-interface timestamps.
17672 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17673 and sometimes 'EMACS_UINT', to represent these timestamps.
17674 This change causes it to use 'Time' uniformly, as that's what X uses.
17675 This makes the code easier to follow, and makes it easier to catch
17676 integer overflow bugs such as Bug#8664.
17677 * frame.c (Fmouse_position, Fmouse_pixel_position):
17678 Use Time, not unsigned long, for user-interface timestamps.
17679 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17680 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17681 * keyboard.h (last_event_timestamp): Likewise.
17682 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17683 * menu.h (xmenu_show): Likewise.
17684 * term.c (term_mouse_position): Likewise.
17685 * termhooks.h (struct input_event.timestamp): Likewise.
17686 (struct terminal.mouse_position_hook): Likewise.
17687 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17688 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17689 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17690 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17691 what it was before.
17692 * menu.h, termhooks.h: Include "systime.h", for Time.
17694 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17695 Don't assume that the difference between two unsigned long values
17696 can fit into an integer. At this point, we know button_down_time
17697 <= event->timestamp, so the difference must be nonnegative, so
17698 there's no need to cast the result if double-click-time is
17699 nonnegative, as it should be; check that it's nonnegative, just in
17700 case. This bug is triggered when events are more than 2**31 ms
17701 apart (about 25 days). (Bug#8664)
17703 * xselect.c (last_event_timestamp): Remove duplicate decl.
17704 (x_own_selection): Remove needless cast to unsigned long.
17706 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17707 that always fit in int. Use a sentinel instead of a counter, to
17708 avoid a temp and to allay GCC's concerns about possible int overflow.
17709 * frame.h (struct frame): Use int for menu_bar_items_used
17710 instead of EMACS_INT, since it always fits in int.
17712 * menu.c (grow_menu_items): Check for int overflow.
17714 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17716 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17717 Before, the code was not consistent. These values cannot exceed
17718 2**31 - 1 so there's no need to make them unsigned.
17719 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17720 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17721 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17723 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17725 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17726 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17727 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17728 presumably because the widths might not match.
17730 * window.c (size_window): Avoid needless test at loop start.
17732 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17734 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17736 2011-05-12 Drew Adams <drew.adams@oracle.com>
17738 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17740 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17742 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17743 `width' to `bar_area_x' and `bar_area_width', respectively.
17744 (x_scroll_run): Take account of fringe background extension.
17746 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17747 Rename local vars `left' and `width' to `bar_area_x' and
17748 `bar_area_width', respectively.
17749 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17750 background extension.
17752 2011-05-10 Jim Meyering <meyering@redhat.com>
17754 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17756 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17758 * image.c (Finit_image_library): Return t for built-in image types,
17759 like pbm and xbm. (Bug#8640)
17761 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17763 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17765 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17767 * w32console.c (Fset_screen_color): Doc fix.
17768 (Fget_screen_color): New function.
17769 (syms_of_ntterm): Defsubr it.
17771 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17772 unlink the temporary file if Fcall_process didn't create it in the
17774 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17775 child process will be redirected to a file specified with `:file'.
17776 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17777 cue to call_process_cleanup not to close that handle.
17779 2011-05-07 Ben Key <bkey76@gmail.com>
17781 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17782 one of two shell specific rules, either bootstrap-temacs-CMD or
17783 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17784 to the previous implementation of the bootstrap-temacs rule.
17785 The bootstrap-temacs-CMD rule is similar to the previous
17786 implementation of the bootstrap-temacs rule except that it
17787 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17790 These changes, along with some changes to nt/configure.bat,
17791 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17792 earlier fix to add support for --cflags and --ldflags options
17793 that include quotes so that it works whether make uses cmd or
17796 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17798 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17799 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17801 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17802 a string. Handle both cases.
17803 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17804 (Fdbus_register_method): Use Qinvalid_function.
17806 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17808 * makefile.w32-in: Update dependencies.
17809 (LISP_H): Add inttypes.h and stdin.h.
17810 (PROCESS_H): Add unistd.h.
17812 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17814 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17815 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17817 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17819 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17821 * term.c (vfatal): Remove stray call to va_end.
17822 It's not needed and the C Standard doesn't allow it here anyway.
17824 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17825 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17827 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17830 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17832 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17834 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17836 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17838 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17840 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17841 * charset.c (Fdefine_charset_internal): Don't initialize
17842 charset.code_space[15]. The value was garbage, on hosts with
17843 32-bit int (Bug#8600).
17845 * lread.c (read_integer): Be more consistent with string-to-number.
17846 Use string_to_number to do the actual conversion; this avoids
17847 rounding errors and fixes some other screwups. Without this fix,
17848 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17849 (digit_to_number): Move earlier, for benefit of read_integer.
17850 Return -1 if the digit is out of range for the base, -2 if it is
17851 not a digit in any supported base. (Bug#8602)
17853 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17855 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17856 to match comment at start of function. This also removes a
17857 GCC warning about overflow in a 32+64-bit port.
17859 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17861 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17862 Reported by Stefan Monnier in
17863 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17864 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17865 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17867 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17868 (EMACS_UINTPTR): Likewise, with uintptr_t.
17870 * lisp.h: Prefer 64-bit EMACS_INT if available.
17871 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17872 on 32-bit hosts that have 64-bit int, so that they can access
17874 However, temporarily disable this change unless the temporary
17875 symbol WIDE_EMACS_INT is defined.
17877 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17879 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17880 This removes an assumption that EMACS_INT and long are the same
17881 width as pointers. The assumption is true for Emacs porting targets
17882 now, but we want to make other targets possible.
17883 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17884 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17885 In the rest of the code, change types of integers that hold casted
17886 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17887 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17888 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17889 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17890 No need to cast type when ORing.
17891 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17892 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17893 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17894 assume EMACS_INT is the same width as char *.
17895 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17896 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17897 Remove no-longer-needed casts.
17898 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17899 (xg_tool_bar_help_callback, xg_make_tool_item):
17900 Use EMACS_INTPTR to hold an integer
17901 that will be cast to void *; this can avoid a GCC warning
17902 if EMACS_INT is not the same width as void *.
17903 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17904 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17905 (current_message_1, set_message_1):
17906 Use a local to convert to proper width without a cast.
17907 * xmenu.c (dialog_selection_callback): Likewise.
17909 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17910 Also, don't assume VALBITS / RAND_BITS is less than 5,
17911 and don't rely on undefined behavior when shifting a 1 left into
17913 * lisp.h (get_random): Change signature to match.
17915 * lread.c (hash_string): Use size_t, not int, for hash computation.
17916 Normally we prefer signed values; but hashing is special, because
17917 it's better to use unsigned division on hash table sizes so that
17918 the remainder is nonnegative. Also, size_t is the natural width
17919 for hashing into memory. The previous code used 'int', which doesn't
17920 retain enough info to hash well into very large tables.
17921 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17923 * dbusbind.c: Don't possibly lose pointer info when converting.
17924 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17925 Use XPNTR rather than XHASH, so that the high-order bits of
17926 the pointer aren't lost when converting through void *.
17928 * eval.c (Fautoload): Don't double-shift a pointer.
17930 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17932 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17934 * gnutls.c (DEF_GNUTLS_FN):
17935 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17937 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17939 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17942 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17944 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17945 New version that can reserve upto 2GB of heap space.
17947 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17949 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17951 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17953 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17954 `gnutls_certificate_set_x509_key_file'.
17956 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17958 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17959 Update dependencies.
17961 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17963 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17964 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17965 Remove unused parameter `fildes'.
17966 * process.c (read_process_output, send_process): Don't pass it.
17968 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17970 Fix previous change: the library cache is defined in w32.c.
17971 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17972 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17974 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17976 Implement dynamic loading of GnuTLS on Windows.
17978 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17979 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17980 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17983 * gnutls.c (Qgnutls_dll): Define.
17984 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17985 (gnutls_*): Declare function pointers.
17986 (init_gnutls_functions): New function to initialize function pointers.
17987 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
17988 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
17989 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17990 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17991 (emacs_gnutls_write, emacs_gnutls_read)
17992 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17993 (Fgnutls_available_p): New function.
17994 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
17995 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
17996 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
17998 * image.c: Include w32.h.
17999 (Vimage_type_cache): Delete.
18000 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18001 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18002 (w32_delayed_load): Move to w32.c.
18004 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18006 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18007 (w32_delayed_load): Move from image.c. When loading a library, record
18008 its filename in the :loaded-from property of the library id.
18009 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18010 Initialize and staticpro them.
18011 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18013 * process.c: Include lisp.h before w32.h, not after.
18014 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18015 instead of gnutls_record_check_pending.
18017 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18019 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18021 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18022 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18025 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18027 * xterm.c (x_set_frame_alpha): Do not set property on anything
18028 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18030 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18032 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18034 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18036 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
18037 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

18046 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18048 * callproc.c: Indentation fixup.
18050 * sysdep.c (wait_for_termination_1): Make static.
18051 (wait_for_termination, interruptible_wait_for_termination):
18052 Move after wait_for_termination_1.
18054 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18056 * sysdep.c (interruptible_wait_for_termination): New function
18057 which is like wait_for_termination, but allows keyboard
18060 * callproc.c (Fcall_process): Add (:file "file") as an option for
18062 (Fcall_process_region): Ditto.
18064 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18066 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18067 rather than `XVECTOR (FOO)->size'.
18069 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18070 inttypes.h, as a gnulib replacement is used if it not available in
18073 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18075 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18076 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18077 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18079 * coding.c (coding_alloc_by_realloc): Error out if destination
18080 will grow beyond MOST_POSITIVE_FIXNUM.
18081 (decode_coding_emacs_mule): Abort if there isn't enough place in
18082 charbuf for the composition carryover bytes. Reserve an extra
18083 space for up to 2 characters produced in a loop.
18084 (decode_coding_iso_2022): Abort if there isn't enough place in
18085 charbuf for the composition carryover bytes.
18087 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18089 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18090 aborting when %lld or %lll format is passed.
18091 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18092 %llo or %llx format is passed. (Bug#8545)
18094 * window.c (window_scroll_line_based): Use a marker instead of
18095 simple variables to record original value of point. (Bug#7952)
18097 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18098 produced by %s or %c overflows available buffer space. (Bug#8545)
18100 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18102 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18103 (SIZE_MAX): Move defn after all includes, as they might #define it.
18105 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18107 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18109 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18111 * keyboard.c (Qdelayed_warnings_hook): Define.
18112 (command_loop_1): Run `delayed-warnings-hook'
18113 if Vdelayed_warnings_list is non-nil.
18114 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18115 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18117 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18119 * doprnt.c (doprnt): Don't return value smaller than the buffer
18120 size if the message was truncated. (Bug#8545).
18122 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18124 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18125 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18127 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18129 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18131 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18133 * makefile.w32-in: Update dependencies.
18135 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18137 Improve `doprnt' and its usage. (Bug#8545)
18138 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18139 `format_end'. Remove support for %l as a conversion specifier.
18140 Don't use xrealloc. Improve diagnostics when the %l size modifier
18141 is used. Update the commentary.
18143 * eval.c (verror): Simplify calculation of size_t.
18145 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18148 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18150 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18153 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18155 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18156 This makes this file independent of the recent pseudovector change.
18158 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18160 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18162 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18163 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18164 Remove unused local.
18165 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18167 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18168 GCC 4.6.0 optimizes based on type-based alias analysis.
18169 For example, if b is of type struct buffer * and v of type struct
18170 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18171 != &v->size, and therefore "v->size = 1; b->size = 2; return
18172 v->size;" must therefore return 1. This assumption is incorrect
18173 for Emacs, since it type-puns struct Lisp_Vector * with many other
18174 types. To fix this problem, this patch adds a new type struct
18175 vectorlike_header that documents the constraints on layout of vectors
18176 and pseudovectors, and helps optimizing compilers not get fooled
18177 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18178 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18179 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18181 (XSETPVECTYPE): Rewrite in terms of new macro.
18182 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18183 This is a bit clearer, and further avoids the possibility of
18184 undesirable aliasing.
18185 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18186 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18187 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18188 since Lisp_Subr is a special case (no "next" field).
18189 (ASIZE): Now uses header.size rather than size.
18190 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18191 to avoid the hassle of writing XVECTOR (foo)->header.size.
18192 (struct vectorlike_header): New type.
18193 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18194 object, to help avoid aliasing.
18195 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18196 (SUBRP): Likewise, since Lisp_Subr is a special case.
18197 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18198 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18199 (struct Lisp_Hash_Table): Combine first two members into a single
18200 struct vectorlike_header member. All uses of "size" and "next" members
18201 changed to be "header.size" and "header.next".
18202 * buffer.h (struct buffer): Likewise.
18203 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18204 * frame.h (struct frame): Likewise.
18205 * process.h (struct Lisp_Process): Likewise.
18206 * termhooks.h (struct terminal): Likewise.
18207 * window.c (struct save_window_data, struct saved_window): Likewise.
18208 * window.h (struct window): Likewise.
18209 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18210 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18211 * buffer.c (init_buffer_once): Likewise.
18212 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18214 * process.c (Fformat_network_address): Use local var for size,
18217 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18219 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18220 * data.c (atof): Remove decl; no longer used or needed.
18221 (digit_to_number): Move to lread.c.
18222 (Fstring_to_number): Use new string_to_number function, to be
18223 consistent with how the Lisp reader treats infinities and NaNs.
18224 Do not assume that floating-point numbers represent EMACS_INT
18225 without losing information; this is not true on most 64-bit hosts.
18226 Avoid double-rounding errors, by insisting on integers when
18227 parsing non-base-10 numbers, as the documentation specifies.
18228 * lisp.h (string_to_number): New decl, replacing ...
18229 (isfloat_string): Remove.
18230 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18231 (read1): Do not accept +. and -. as integers; this
18232 appears to have been a coding error. Similarly, do not accept
18233 strings like +-1e0 as floating point numbers. Do not report
18234 overflow for integer overflows unless the base is not 10 which
18235 means we have no simple and reliable way to continue.
18236 Break out the floating-point parsing into a new
18237 function string_to_number, so that Fstring_to_number parses
18238 floating point numbers consistently with the Lisp reader.
18239 (digit_to_number): Move here from data.c. Make it static inline.
18240 (E_CHAR, EXP_INT): Remove, replacing with ...
18241 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18242 (string_to_number): New function, replacing isfloat_string.
18243 This function checks for valid syntax and produces the resulting
18244 Lisp float number too. Rework it so that string-to-number
18245 no longer mishandles examples like "1.0e+". Use strtoumax,
18246 so that overflow for non-base-10 numbers is reported only when
18247 there's no portable and simple way to convert to floating point.
18249 * textprop.c (set_text_properties_1): Rewrite for clarity,
18250 and to avoid GCC warning about integer overflow.
18252 * intervals.h (struct interval): Use EMACS_INT for members
18253 where EMACS_UINT might cause problems. See
18254 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18255 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18256 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18258 (offset_intervals): Tell GCC not to worry about length overflow
18259 when negating a negative length.
18261 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18262 (overrun_check_free): Likewise.
18264 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18265 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18268 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18269 (gnutls_make_error): Rename local to avoid shadowing.
18270 (gnutls_emacs_global_deinit): ifdef out; not used.
18271 (Fgnutls_boot): Use const for pointer to readonly storage.
18272 Comment out unused local. Fix pointer signedness problems.
18274 * lread.c (openp): Don't stuff size_t into an 'int'.
18275 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18276 about possible signed overflow.
18278 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18279 (GDK_KEY_g): Don't define if already defined.
18280 (xg_prepare_tooltip): Avoid pointer signedness problem.
18281 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18283 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18284 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18286 * xfns.c (Fx_window_property): Simplify a bit,
18287 to make a bit faster and to avoid GCC 4.6.0 warning.
18288 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18290 * fns.c (internal_equal): Don't assume size_t fits in int.
18292 * alloc.c (compact_small_strings): Tighten assertion a little.
18294 Replace pEd with more-general pI, and fix some printf arg casts.
18295 * lisp.h (pI): New macro, generalizing old pEd macro to other
18296 conversion specifiers. For example, use "...%"pI"d..." rather
18297 than "...%"pEd"...".
18298 (pEd): Remove. All uses replaced with similar uses of pI.
18299 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18300 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18301 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18302 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18303 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18304 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18305 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18307 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18308 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18309 * print.c (safe_debug_print, print_object): Likewise.
18310 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18312 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18313 avoiding the 0 flag, which is not portable.
18314 * process.c (Fmake_network_process): Use pI to avoid cast.
18315 * region-cache.c (pp_cache): Likewise.
18316 * xdisp.c (decode_mode_spec): Likewise.
18317 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18318 behavior on 64-bit hosts with printf arg.
18319 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18320 (x_stop_queuing_selection_requests): Likewise.
18321 (x_get_window_property): Don't truncate byte count to an 'int'
18324 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18325 here, since it parses constructs like leading '-' and spaces,
18326 which are not wanted; and it overflows with large numbers.
18327 Instead, simply match F[0-9]+, which is what is wanted anyway.
18329 * alloc.c: Remove unportable assumptions about struct layout.
18330 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18331 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18332 (allocate_vectorlike, make_pure_vector): Use the new macros,
18333 plus offsetof, to remove unportable assumptions about struct layout.
18334 These assumptions hold on all porting targets that I know of, but
18335 they are not guaranteed, they're easy to remove, and removing them
18336 makes further changes easier.
18338 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18339 This doesn't fix a bug but makes the code clearer.
18340 (string_overrun_cookie): Now const. Use initializers that
18341 don't formally overflow signed char, to avoid warnings.
18342 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18343 can cause Emacs to crash when string overrun checking is enabled.
18344 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18345 multiple of sizeof (EMACS_INT); it need not be, if
18346 alignof(EMACS_INT) < sizeof (EMACS_INT).
18347 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18349 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18376 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18378 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18379 "cast to pointer from integer of different size".
18381 Improve doprnt and its use in verror. (Bug#8545)
18382 * doprnt.c (doprnt): Document the set of format control sequences
18383 supported by the function. Use SAFE_ALLOCA instead of always
18386 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18387 is one byte too soon. Don't use xrealloc; instead xfree and
18390 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18392 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

18396 gnutls_global_initialized. Added internals for the
18397 :verify-hostname-error, :verify-error, and :verify-flags
18398 parameters of `gnutls-boot' and documented those parameters in the
18399 docstring. Start callback support.
18400 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18401 unless a fatal error occurred. Call gnutls_alert_send_appropriate

18477 Many local variables are now size_t instead of int or unsigned.
18478 Improve overflow protection. Support `l' modifier for integer
18479 conversions. Support %l conversion. Don't assume an EMACS_INT
18480 argument for integer conversions and for %c.
18482 * lisp.h (doprnt): Restore prototype.
18484 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

18499 * callint.c (Fcall_interactively): When displaying error message
18500 about invalid control letter, pass the character's codepoint, not

18502 in octal and display also its hex code.
18504 * character.c (char_string): Use %x to display the (unsigned)
18505 codepoint of an invalid character, to avoid displaying a bogus
18508 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18509 `error', not SYMBOL_NAME itself.
18511 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

18587 * dispextern.h (struct redisplay_interface): Rename param
18588 to avoid shadowing.
18589 * termhooks.h (struct terminal): Likewise.

18706 * nsfont.m: Fixed bugs in ns_get_family and
18707 ns_descriptor_to_entity that were caused by using free to
18708 deallocate memory blocks that were allocated by xmalloc (via
18709 xstrdup). This caused Emacs to crash when compiled with
18710 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18711 --enable-checking=xmallocoverrun). xfree is now used to
18712 deallocate these memory blocks.

19126 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19127 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19128 Remove decls, since these functions are now static.
19129 (Funintern, Fget_internal_run_time): New decls, since these functions
19130 were already external.
19132 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19133 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19139 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19140 Mark functions with DEFUE instead of DEFUN,
19141 if they are used in other modules.
19142 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19143 decls for now-static functions.
19144 * buffer.h (Fdelete_overlay): Remove decl.
19145 * callproc.c (Fgetenv_internal): Mark as internal.

19180 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19182 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19183 when at ZV. (Bug#8487)
19185 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19187 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19189 * keyboard.c (parse_tool_bar_item): Likewise.
19190 * sound.c (sound_cleanup, alsa_close): Likewise.
19191 * termcap.c (tgetent): Likewise.

19193 * xsettings.c (read_and_apply_settings): Likewise.
19195 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19196 (overrun_check_free): Protoize.
19198 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19200 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19201 since callers should never pass a negative size.
19202 Change the signature to match that of plain 'read' and 'write'; see
19203 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19204 * lisp.h: Update prototypes of emacs_write and emacs_read.
19206 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19208 * xdisp.c (redisplay_window): Don't try to determine the character
19209 position of the scroll margin if the window start point w->startp
19210 is outside the buffer's accessible region. (Bug#8468)
19212 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19214 Fix write-region and its subroutines for buffers > 2GB.
19215 * fileio.c (a_write, e_write): Modify declaration of arguments and
19216 local variables to support buffers larger than 2GB.
19217 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19219 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19220 argument, local variables, and return value.
19222 * lisp.h: Update prototypes of emacs_write and emacs_read.
19224 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19226 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19228 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19230 Fix more problems found by GCC 4.6.0's static checks.
19232 * xdisp.c (vmessage): Use a better test for character truncation.
19234 * charset.c (load_charset_map): <, not <=, for optimization,
19235 and to avoid potential problems with integer overflow.
19236 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19237 * casetab.c (set_identity, shuffle): Likewise.
19238 * editfns.c (Fformat): Likewise.
19239 * syntax.c (skip_chars): Likewise.
19241 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19242 This also lets GCC 4.6.0 generate slightly better loop code.
19244 * callint.c (Fcall_interactively): <, not <=, for optimization.
19245 (Fcall_interactively): Count the number of arguments produced,
19246 not the number of arguments given. This is simpler and lets GCC
19247 4.6.0 generate slightly better code.
19249 * ftfont.c: Distingish more carefully between FcChar8 and char.
19250 The previous code passed unsigned char * to a functions like
19251 strlen and xstrcasecmp that expect char *, which does not
19252 conform to the C standard.
19253 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19254 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19255 char * when the C standard requires it.
19257 * keyboard.c (read_char): Remove unused var.
19259 * eval.c: Port to Windows vsnprintf (Bug#8435).
19260 Include <limits.h>.
19261 (SIZE_MAX): Define if the headers do not.
19262 (verror): Do not give up if vsnprintf returns a negative count.
19263 Instead, grow the buffer. This ports to Windows vsnprintf, which
19264 does not conform to C99. Problem reported by Eli Zaretskii.
19265 Also, simplify the allocation scheme, by avoiding the need for
19266 calling realloc, and removing the ALLOCATED variable.
19268 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19270 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19271 But keep the doprint source code for now, as we might revamp it
19272 and use it again (Bug#8435).
19273 * lisp.h (doprnt): Remove.
19274 * Makefile.in (base_obj): Remove doprnt.o.
19275 * deps.mk (doprnt.o): Remove.
19277 error: Print 32- and 64-bit integers portably (Bug#8435).
19278 Without this change, on typical 64-bit hosts error ("...%d...", N)
19279 was used to print both 32- and 64-bit integers N, which relied on
19280 undefined behavior.
19281 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19282 * lisp.h (error, verror): Mark as printf-like functions.
19283 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19284 Report overflow in size calculations when allocating printf buffer.
19285 Do not truncate output string at its first null byte.
19286 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19287 Truncate the output at a character boundary, since vsnprintf does not
19289 * charset.c (check_iso_charset_parameter): Convert internal
19290 character to string before calling 'error', since %c now has the
19292 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19293 overflow when computing char to be passed to 'error'. Do not
19294 pass Lisp_Object to 'error'; pass the integer instead.
19295 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19296 formatted with plain %d.
19298 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19300 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19302 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19304 * xterm.c (x_catch_errors): Remove duplicate declaration.
19306 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19308 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19310 2011-04-10 Jim Meyering <meyering@redhat.com>
19312 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19313 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19314 return ssize_t not "int", and use size_t as the buffer length.
19315 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19316 * gnutls.h: Update declarations.
19317 * process.c (read_process_output): Use ssize_t, to match.
19318 (send_process): Likewise.
19320 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19322 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19324 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19326 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19327 Use unsigned char, to match FcChar8 type definition.
19329 * xterm.c (handle_one_xevent):
19330 * xmenu.c (create_and_show_popup_menu):
19331 * xselect.c (x_decline_selection_request)
19332 (x_reply_selection_request): Avoid type-punned deref of X events.
19334 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19336 Fix some uses of `int' instead of EMACS_INT.
19337 * search.c (string_match_1, fast_string_match)
19338 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19339 (scan_buffer, find_next_newline_no_quit)
19340 (find_before_next_newline, search_command, Freplace_match)
19341 (Fmatch_data): Make some `int' variables be EMACS_INT.
19343 * xdisp.c (display_count_lines): 3rd argument and return value now
19344 EMACS_INT. All callers changed.
19345 (pint2hrstr): Last argument is now EMACS_INT.
19347 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19348 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19349 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19360 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19361 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19363 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19364 (encode_invocation_designation): Last argument P_NCHARS is now
19366 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19367 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19369 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19372 * ccl.c (Fccl_execute_on_string): Declare some variables
19375 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19377 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19379 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19381 * process.c (Fformat_network_address): Doc fix.
19383 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19385 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19387 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19389 * keyboard.c (read_char): Call Lisp function help-form-show,
19390 instead of using internal_with_output_to_temp_buffer.
19391 (Qhelp_form_show): New var.
19392 (syms_of_keyboard): Use DEFSYM macro.
19394 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19396 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19398 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19400 * process.c (Flist_processes): Remove to Lisp.
19401 (list_processes_1): Delete.
19403 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19405 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19407 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19409 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19411 Fix more problems found by GCC 4.6.0's static checks.
19413 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19415 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19417 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19419 * xdisp.c (vmessage): Mark as a printf-like function.
19421 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19423 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19425 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19426 printf-like functions.
19427 (tiff_load): Add casts to remove these marks before passing them
19428 to system-supplied API.
19430 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19432 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19433 This avoids several warnings with gcc -Wstrict-overflow.
19434 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19435 directly, rather than having caller test rule sign. This avoids
19436 some unnecessary tests.
19437 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19438 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19439 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19441 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19442 (xfont_open): Avoid unnecessary tests.
19444 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19446 * composite.h, composite.c (composition_gstring_put_cache):
19447 Use EMACS_INT, not int, for length.

19450 breaking out part of COMPOSITION_DECODE_RULE.
19451 (COMPOSITION_DECODE_RULE): Use it.

19453 by using the new macro.
19455 * textprop.c (set_text_properties_1): Change while to do-while,
19456 since the condition is always true at first.
19458 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19459 (interval_deletion_adjustment): Return unsigned value.
19462 * process.c (list_processes_1, create_pty, read_process_output):

19472 (update_syntax_table): Use unsigned instead of int.
19474 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19475 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19476 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19478 * print.c (print_error_message): Avoid int overflow.
19480 * font.c (font_list_entities): Redo for clarity,
19481 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19483 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19484 (font_score): Avoid potential overflow in diff calculation.
19486 * fns.c (substring_both): Remove var that is set but not used.
19487 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19489 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19491 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19492 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19493 can always succeed if overflow has undefined behavior.
19495 * search.c (boyer_moore, wordify): Remove vars set but not used.
19496 (wordify): Omit three unnecessary tests.
19498 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19499 All callers changed. This avoids the need for an unused var.
19501 * casefiddle.c (casify_region): Remove var that is set but not used.
19503 * dired.c (file_name_completion): Remove var that is set but not used.
19505 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19507 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19508 (Finsert_file_contents): Remove unnecessary code checking fd.
19510 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19511 Check for integer overflow on size calculations.
19513 * buffer.c (Fprevious_overlay_change): Remove var that is set
19516 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19517 Remove vars that are set but not used.
19518 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19519 (timer_check_2): Mark vars as initialized.
19521 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19523 * image.c (lookup_image): Remove var that is set but not used.
19524 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19526 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19527 that are set but not used.
19529 * xfns.c (make_invisible_cursor): Don't return garbage
19530 if XCreateBitmapFromData fails (Bug#8410).
19532 * xselect.c (x_get_local_selection, x_handle_property_notify):
19533 Remove vars that are set but not used.
19535 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19536 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19538 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19539 Remove var that is set but not used.

19541 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19542 Check for overflow.
19544 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19545 (map_tty_color) [!defined MSDOS]: Likewise.
19547 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19549 * coding.c: Remove vars that are set but not used.
19550 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19551 All callers changed.
19552 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19553 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19554 (decode_coding_charset): Remove vars that are set but not used.
19556 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19557 that is set but not used.
19559 * print.c (print_object): Remove var that is set but not used.
19561 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19562 The gnulib version avoids calling malloc in the usual case,
19563 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19564 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19565 * filelock.c (current_lock_owner): Likewise.
19566 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19567 * sysdep.c: Include allocator.h, careadlinkat.h.

19598 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19599 (ns_get_family): Likewise.
19601 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

19607 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19610 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19612 Add lexical binding.

19623 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19625 (syms_of_lread): Declare `lexical-binding'.
19627 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19629 * keyboard.c (eval_dyn): New fun.
19630 (menu_item_eval_property): Use it.

19634 * fns.c (concat, mapcar1): Accept byte-code-functions.
19636 * eval.c (Fsetq): Handle lexical vars.
19637 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19638 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19639 (FletX, Flet): Obey lexical binding.
19640 (Fcommandp): Handle closures.
19641 (Feval): New `lexical' arg.
19642 (eval_sub): New function extracted from Feval. Use it almost
19643 everywhere where Feval was used. Look up vars in lexical env.
19645 (Ffunctionp): Move from subr.el.
19646 (Ffuncall): Handle closures.
19647 (apply_lambda): Remove `eval_flags'.
19648 (funcall_lambda): Handle closures and new byte-code-functions.
19649 (Fspecial_variable_p): New function.
19650 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19651 but without exporting it to Lisp.
19653 * doc.c (Fdocumentation, store_function_docstring):
19654 * data.c (Finteractive_form): Handle closures.
19656 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19659 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19661 (exec_byte_code): New function extracted from Fbyte_code to handle new
19662 calling convention for byte-code-functions. Add new byte-codes.
19664 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19666 * alloc.c (Fmake_symbol): Init new `declared_special' field.

19670 * xdisp.c (redisplay_internal): Fix prototype.
19672 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19674 * xdisp.c (SCROLL_LIMIT): New macro.
19675 (try_scrolling): Use it when setting scroll_limit.
19676 Limit scrolling to 100 screen lines.
19677 (redisplay_window): Even when falling back on "recentering",
19678 position point in the window according to scroll-conservatively,
19679 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19681 (try_scrolling): When point is above the window, allow searching
19682 as far as scroll_max, or one screenful, to compute vertical
19683 distance from PT to the scroll margin position. This prevents
19684 try_scrolling from unnecessarily failing when
19685 scroll-conservatively is set to a value slightly larger than the
19686 window height. Clean up the case of PT below the margin at bottom
19687 of window: scroll_max can no longer be INT_MAX. When aggressive
19688 scrolling is in use, don't let point enter the opposite scroll
19689 margin as result of the scroll.
19690 (syms_of_xdisp) <scroll-conservatively>: Document the
19691 threshold of 100 lines for never-recentering scrolling.
19693 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

19701 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19703 * indent.c (Fvertical_motion):
19704 * window.c (window_scroll_pixel_based, Frecenter):
19705 Don't pass `need_y_p' to `move_it_by_lines'.
19707 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19709 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19710 steal a few bits to be more compact.
19711 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19712 Remove unneeded casts.
19714 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19716 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19718 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19719 binding" message (bug#7967).
19721 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19723 Fix more problems found by GCC 4.6.0's static checks.
19725 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19726 Remove unused local var.
19728 * editfns.c (Fmessage_box): Remove unused local var.
19730 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19731 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19732 Omit unused local vars.
19733 * window.c (shrink_windows): Omit unused local var.
19734 * menu.c (digest_single_submenu): Omit unused local var.
19735 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19736 Omit unused local var.
19738 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19739 Don't assume string length fits in int.
19740 (keyremap_step, read_key_sequence): Use size_t for sizes.
19741 (read_key_sequence): Don't check last_real_key_start redundantly.
19743 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19744 instead of alloca (Bug#8344).
19746 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19747 (Fbacktrace_frame): Don't assume nframes fits in int.
19749 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19756 * cm.c (calccost): Turn while-do into do-while, for clarity.
19758 * keyboard.c (syms_of_keyboard): Use the same style as later
19759 in this function when indexing through an array. This also
19760 works around GCC bug 48267.
19762 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19764 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19766 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19767 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19769 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19770 This avoids undefined behavior on integer overflow, and is a bit
19771 more convenient anyway since it is compared to a size_t variable.
19773 Variadic C functions now count arguments with size_t, not int.
19774 This avoids an unnecessary limitation on 64-bit machines, which
19775 caused (substring ...) to crash on large vectors (Bug#8344).

19785 * fns.c (concat): Likewise.
19786 * frame.c (x_set_frame_parameters): Likewise.
19787 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19788 0 if not found, not -1. All callers changed.
19790 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19791 (stack_copy_size): Now size_t, not int.
19792 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19794 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19796 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

19813 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19814 don't set the hook to nil, but remove the offending function instead.
19815 (Qcommand_hook_internal): Remove, unused.
19816 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19817 Vcommand_hook_internal.
19819 * eval.c (enum run_hooks_condition): Remove.
19820 (funcall_nil, funcall_not): New functions.
19821 (run_hook_with_args): Call each function through a `funcall' argument.

20007 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20008 the first time through the loop, since we know p0 < p1 then.
20009 This also avoids a gcc -Wstrict-overflow warning.
20011 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20012 leading to a memory leak, possible in functions like
20013 load_charset_map_from_file that can allocate an unbounded number
20014 of objects (Bug#8318).
20016 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20017 that could (at least in theory) be that large.
20019 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20020 This is less likely to overflow, and avoids undefined behavior if
20021 overflow does occur. All callers changed. Use strtoul to scan
20022 for the unsigned long integer.
20023 (pint2hrstr): Simplify and tune code slightly.
20024 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20026 * scroll.c (do_scrolling): Work around GCC bug 48228.
20027 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
20029 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
20030 This also avoids a warning with gcc -Wstrict-overflow.
20031 (validate_x_resource_name): Simplify count usage.
20032 This also avoids a warning with gcc -Wstrict-overflow.
20034 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20037 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20039 * process.c (Fmake_network_process): Use socklen_t, not int,
20040 where POSIX says socklen_t is required in portable programs.
20041 This fixes a porting bug on hosts like 64-bit HP-UX, where
20042 socklen_t is wider than int (Bug#8277).
20043 (Fmake_network_process, server_accept_connection):
20044 (wait_reading_process_output, read_process_output):
20047 * process.c: Rename or move locals to avoid shadowing.

20049 (read_process_output_error_handler, exec_sentinel_error_handler):
20050 Rename or move locals.
20051 (Fmake_network_process): Define label "retry_connect" only if needed.
20052 (Fnetwork_interface_info): Fix pointer signedness.
20053 (process_send_signal): Add cast to avoid pointer signedness problem.
20054 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
20055 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
20057 Make tparam.h and terminfo.c consistent.
20058 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20059 Include tparam.h instead, since it declares them.
20060 * cm.h (PC): Remove extern decl; tparam.h now does this.
20061 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20062 * terminfo.c: Include tparam.h, to check interfaces.
20063 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20064 (tparam): Adjust signature to match interface in tparam.h;
20065 this removes some undefined behavior. Check that outstring and len
20066 are zero, which they always are with Emacs.
20067 * tparam.h (PC, BC, UP): New extern decls.
20069 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20070 (xftfont_open): Rename locals to avoid shadowing.
20072 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

20082 * xml.c (make_dom): Now static.
20084 * composite.c (composition_compute_stop_pos): Rename local to
20086 (composition_reseat_it): Remove unused locals.
20087 (find_automatic_composition, composition_adjust_point): Likewise.
20088 (composition_update_it): Mark var as initialized.
20089 (find_automatic_composition): Mark vars as initialized,
20090 with a FIXME (Bug#8290).

20093 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
20094 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20095 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20096 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20097 to avoid shadowing.
20099 * textprop.c (property_change_between_p): Remove; unused.
20101 * intervals.c (interval_start_pos): Now static.
20103 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20106 Rename locals to avoid shadowing.
20108 * sound.c (wav_play, au_play, Fplay_sound_internal):
20109 Fix pointer signedness.
20110 (alsa_choose_format): Remove unused local var.
20111 (wav_play): Initialize a variable to 0, to prevent undefined
20112 behavior (Bug#8278).
20114 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20116 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20118 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20119 clobbering (Bug#8298).
20120 * sysdep.c (sys_subshell): Likewise.
20121 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20123 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20124 This should get cleaned up, so that child_setup has the
20125 same signature on all platforms.
20127 * callproc.c (call_process_cleanup): Now static.
20128 (relocate_fd): Rename locals to avoid shadowing.
20130 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20132 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20133 not to be necessary, and produces flickering.
20135 2011-03-20 Glenn Morris <rgm@gnu.org>
20137 * config.in: Remove file.
20139 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20141 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20142 are now in src/globals.h.
20143 (syms_of_minibuf): Remove spurious & from previous change.
20145 2011-03-20 Leo Liu <sdl.web@gmail.com>
20147 * minibuf.c (completing-read-function): New variable.
20148 (completing-read-default): Rename from completing-read.
20149 (completing-read): Call completing-read-function.
20151 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20153 * xfaces.c (Fx_load_color_file):
20154 Read color file from absolute filename (bug#8250).
20156 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20158 * makefile.w32-in: Update dependencies.
20160 2011-03-17 Eli Zaretskii <eliz@gnu.org>
20162 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

20169 (sigchld_handler): Now static.
20171 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.

20182 (CONSTANTLIM): Remove; unused.
20183 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20184 Define only if needed.
20186 * unexelf.c (unexec): Name an expression,
20187 to avoid gcc -Wbad-function-cast warning.
20188 Use a different way to cause a compilation error if anyone uses
20189 n rather than nn, a way that does not involve shadowing.
20190 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20192 * deps.mk (unexalpha.o): Remove; unused.
20194 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20195 * unexec.h: New file.
20196 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20197 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20198 Depend on unexec.h.
20199 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
20200 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
20201 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
20202 Change as necessary to match prototype in unexec.h.

20237 * floatfns.c (domain_error2): Define only if needed.
20238 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
20240 * alloc.c (mark_backtrace): Move decl from here ...

20249 * callint.c (quotify_arg, quotify_args): Now static.
20250 (Fcall_interactively): Rename locals to avoid shadowing.
20251 Use const pointer when appropriate.
20253 * lisp.h (get_system_name, get_operating_system_release):

20255 * process.c (get_operating_system_release): Move decl to lisp.h.
20256 * xrdb.c (get_system_name): Likewise.
20257 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
20258 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20259 some of which prompt warnings from gcc -Wbad-function-cast.
20260 (Fformat_time_string, Fencode_time, Finsert_char):
20261 (Ftranslate_region_internal, Fformat):
20262 Rename or remove local vars to avoid shadowing.

20265 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20268 * lisp.h (eassert): Check that the argument compiles, even if

20287 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20288 (GC_STRING_CHARS): Remove; not used.
20289 (Fmemory_limit): Cast sbrk's returned value to char *.
20291 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20292 avoids undefined behavior in theory.
20294 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20296 Use functions, not macros, for up- and down-casing (Bug#8254).
20297 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20298 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20299 to use the following functions instead of these macros.
20300 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20301 EMACS_INT, since callers assume the returned value fits in int.
20302 (upcase1): Likewise, for UPCASE_TABLE.
20303 (uppercasep, lowercasep, upcase): New static inline functions.
20304 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20313 which gcc can warn about.
20314 (regex_compile, re_match_2_internal): Mark locals as initialized.
20315 (RETALLOC_IF): Define only if needed.
20316 (WORDCHAR_P): Likewise. This one is never needed, but is used
20317 only in a comment talking about a compiler bug, so put inside
20318 the #if 0 of that comment.
20319 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20320 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20323 * search.c (boyer_moore): Rename locals to avoid shadowing.
20324 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

20337 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
20338 Rename locals to avoid shadowing.
20339 (Fvertical_motion): Mark locals as initialized.
20341 * casefiddle.c (casify_object, casify_region): Now static.
20342 (casify_region): Mark local as initialized.
20344 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
20346 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20347 New macros, so that the caller can use some names other than
20348 gcpro1, gcpro2, etc.
20349 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20351 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20352 argument, for consistency with GCPRO2_VAR, etc: it is now the
20353 prefix of the variable, not the variable itself. All uses
20355 * dired.c (directory_files_internal, file_name_completion):
20356 Rename locals to avoid shadowing.
20358 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20359 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20360 dired.c's scmp function, had undefined behavior.
20361 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20362 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20363 * buffer.h: ... to here, because these macros use current_buffer,
20364 and the new implementation with inline functions needs to have
20365 current_buffer in scope now, rather than later when the macros
20367 (downcase, upcase1): New static inline functions.
20368 (DOWNCASE, UPCASE1): Reimplement using these functions.
20369 This avoids undefined behavior in expressions like
20370 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20371 from race conditions in accessing the global variables
20372 case_temp1 and case_temp2.
20373 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20374 * lisp.h (case_temp1, case_temp2): Remove their decls.
20375 * character.h (ASCII_CHAR_P): Move from here ...
20376 * lisp.h: ... to here, so that the inline functions mentioned
20377 above can use them.
20379 * dired.c (directory_files_internal_unwind): Now static.
20381 * fileio.c (file_name_as_directory, directory_file_name):
20382 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
20384 (file_name_as_directory): Use const pointers when appropriate.
20385 (Fexpand_file_name): Likewise. In particular, newdir might
20386 point at constant storage, so make it a const pointer.
20387 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20388 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20390 (Fset_file_times, Finsert_file_contents, auto_save_error):
20391 Rename locals to avoid shadowing.

20395 to avoid shadowing.
20397 * marker.c (bytepos_to_charpos): Remove; unused.
20399 * lisp.h (verify_bytepos, count_markers): New decls,
20400 so that gcc does not warn that these functions aren't declared.
20402 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20403 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20404 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20405 (copy_text): Remove unused local var.
20407 * filelock.c (within_one_second): Now static.
20408 (lock_file_1): Rename local to avoid shadowing.
20410 * buffer.c (fix_overlays_before): Mark locals as initialized.
20411 (fix_start_end_in_overlays): Likewise. This function should be
20412 simplified by using pointers-to-pointers, but that's a different
20414 (switch_to_buffer_1): Now static.
20415 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20416 (report_overlay_modification): Rename locals to avoid shadowing.
20418 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20419 Fix pointer signedness issue.
20420 (sys_subshell): Mark local as volatile if checking for lint,
20421 to suppress a gcc -Wclobbered warning that does not seem to be right.
20422 (MAXPATHLEN): Define only if needed.
20424 * process.c (serial_open, serial_configure): Move decls from here ...
20425 * systty.h: ... to here, so that they can be checked.
20427 * fns.c (get_random, seed_random): Move extern decls from here ...
20428 * lisp.h: ... to here, so that they can be checked.
20430 * sysdep.c (reset_io): Now static.
20431 (wait_for_termination_signal): Remove; unused.
20433 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20434 (copy_keymap_item, append_key, push_text_char_description):
20436 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
20437 (DENSE_TABLE_SIZE): Remove; unused.
20438 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20439 (describe_map_tree):
20440 Rename locals to avoid shadowing.
20442 * keyboard.c: Declare functions static if they are not used elsewhere.
20443 (echo_char, echo_dash, cmd_error, top_level_2):
20444 (poll_for_input, handle_async_input): Now static.
20445 (read_char, kbd_buffer_get_event, make_lispy_position):
20446 (make_lispy_event, make_lispy_movement, apply_modifiers):
20447 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
20448 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
20449 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
20450 (read_key_sequence, read_char): Mark locals as initialized.
20451 (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.
20453 * keyboard.h (make_ctrl_char): New decl.
