112 (hinst): Remove unneeded extern declaration.
113 (_start): Remove initialization of above variables; remove

258 * w32.c (unsetenv): Return 0 if the input string is too long.
260 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

275 (environbuf): Remove static var. All uses removed.
276 (Fset_time_zone_rule): Do not save TZ and environ;
277 no longer needed here.
278 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
279 Move to inside set_time_zone_rule; they don't need file scope any more.
280 (set_time_zone_rule): Maintain the TZ=value string separately.
281 (syms_of_editfns): Don't initialize initial_tz;
282 init_editfns now does it.
283 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
284 * lisp.h (xputenv): New decl.
286 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

302 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
303 Remove USG and vlimit methods; no longer used these days.
304 Add #error catchall just in case.
306 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
307 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
308 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
309 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.

311 (record_child_status_change, handle_child_signal, deliver_child_signal)

315 (abbr_to_signal): New static function.
316 (Fsignal_process): Use it to convert signal names to ints.
317 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than

319 (emacs_sigaction_init): Assume SIGCHLD is defined.
320 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,

330 This will cause a production Emacs to dump core instead of
333 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
335 * frame.c (make_frame): Do not set window's buffer to t.
336 * window.c (Fsplit_window_internal): Likewise. Previously it was
337 used to indicate that the window is being set up. Now we use
338 set_window_buffer for all new windows, so the condition in ...
339 (Fset_window_buffer): ... is always true and can be removed.
341 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
343 Convenient macro to check whether the buffer is hidden.
344 * buffer.h (BUFFER_HIDDEN_P): New macro.

351 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
352 if the child process is still running. Instead, exit the wait
353 loop and return zero. (Bug#13086)
355 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
357 * frame.h (x_char_width, x_char_height): Remove prototypes.

368 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
370 Fix a recently-introduced delete-process race condition.
371 * callproc.c, process.h (record_kill_process):
372 New function, containing part of the old call_process_kill.
373 (call_process_kill): Use it.
374 This does not change call_process_kill's behavior.
375 * process.c (Fdelete_process): Use record_kill_process to fix a
376 race condition that could cause Emacs to lose track of a child.
378 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
380 Avoid code duplication between prev_frame and next_frame.
381 * frame.c (candidate_frame): New function. Add comment.
382 (prev_frame, next_frame): Use it. Adjust comment.
384 2012-12-06 Eli Zaretskii <eliz@gnu.org>
386 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
387 fails, signal an error instead of continuing with an empty
389 Encode expanded temp file pattern before passing it to mkstemp or
392 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
393 Encode the file name before passing it to dostounix_filename, in
394 case it will downcase it (under w32-downcase-file-names).
397 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
399 Minor call-process cleanups.
400 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
401 at the same time as other platforms, to simplify analysis.
402 No need for fd0_volatile since we have synch_process_fd.
403 Avoid needless emacs_close; arg is always negative.
405 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
407 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
410 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
412 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
413 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
414 and mouse_face_hidden members to a bitfields.
415 * frame.h (struct frame): Remove set-but-not-used space_width member.
416 (FRAME_SPACE_WIDTH): Remove.
417 * nsterm.m, w32term.c, xterm.c: Adjust users.
418 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
419 member. Adjust users. Convert term_initted, delete_in_insert_mode,
420 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
421 members to a bitfields.
423 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
425 Don't let call-process be a zombie factory (Bug#12980).
426 Fixing this bug required some cleanup of the signal-handling code.
427 As a side effect, this change also fixes a longstanding rare race
428 condition whereby Emacs could mistakenly kill unrelated processes,
429 and it fixes a bug where a second C-g does not kill a recalcitrant
430 synchronous process in GNU/Linux and similar platforms.
431 The patch should also fix the last vestiges of Bug#9488,
432 a bug which has mostly been fixed on the trunk by other changes.
433 * callproc.c, process.h (synch_process_alive, synch_process_death)
434 (synch_process_termsig, sync_process_retcode):
435 Remove. All uses removed, to simplify analysis and so that
436 less consing is done inside critical sections.
437 * callproc.c (call_process_exited): Remove. All uses replaced
438 with !synch_process_pid.
439 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
440 These take the role of what used to be in unwind-protect arg.
442 (block_child_signal, unblock_child_signal):
443 New functions, to avoid races that could kill innocent-victim processes.
444 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
445 (call_process_kill): Record killed processes as deleted, so that
446 zombies do not clutter up the system. Do this inside a critical
447 section, to avoid a race that would allow the clutter.
448 (call_process_cleanup): Fix code so that the second C-g works again
449 on common platforms such as GNU/Linux.
450 (Fcall_process): Create the child process in a critical section,
451 to fix a race condition. If creating an asynchronous process,
452 record it as deleted so that zombies do not clutter up the system.
453 Do unwind-protect for WINDOWSNT too, as that's simpler in the
454 light of these changes. Omit unnecessary call to emacs_close
455 before failure, as the unwind-protect code does that.
456 * callproc.c (call_process_cleanup):
457 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
458 * process.c (record_deleted_pid): New function, containing
459 code refactored out of Fdelete_process.
460 (Fdelete_process): Use it.
461 (process_status_retrieved): Remove. All callers changed to use
463 (record_child_status_change): Remove, folding its contents into ...
464 (handle_child_signal): ... this signal handler. Now, this
465 function is purely a handler for SIGCHLD, and is not called after
466 a synchronous waitpid returns; the synchronous code is moved to
467 wait_for_termination. There is no need to worry about reaping
468 more than one child now.
469 * sysdep.c (get_child_status, child_status_changed): New functions.
470 (wait_for_termination): Now takes int * status and bool
471 interruptible arguments, too. Do not record child status change;
472 that's now the caller's responsibility. All callers changed.
473 Reimplement in terms of get_child_status.
474 (wait_for_termination_1, interruptible_wait_for_termination):
475 Remove. All callers changed to use wait_for_termination.
476 * syswait.h: Include <stdbool.h>, for bool.
477 (record_child_status_change, interruptible_wait_for_termination):
479 (record_deleted_pid, child_status_changed): New decls.
480 (wait_for_termination): Adjust to API changes noted above.
482 * bytecode.c, lisp.h (Qbytecode): Remove.
483 No longer needed after 2012-11-20 interactive-p changes.
485 2012-12-03 Eli Zaretskii <eliz@gnu.org>
487 * xdisp.c (redisplay_window): If the cursor is visible, but inside
488 the scroll margin, move point outside the margin. (Bug#13055)
490 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
492 * gtkutil.c (my_log_handler): New function.
493 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).

507 (safe_alloca_unwind): Use it.
508 * lisp.h (free_save_value): New prototype.
509 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.

539 Fix xpalloc confusion after memory is exhausted.
540 * alloc.c (xpalloc): Comment fix.
541 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
542 and signals an error, do not clear charset_table_size, as
543 charset_table is still valid.
544 * doprnt.c (evxprintf): Clear *BUF after freeing it.
546 Use execve to avoid need to munge environ (Bug#13054).
547 * callproc.c (Fcall_process):
548 * process.c (create_process):
549 Don't save and restore environ; no longer needed.
550 * callproc.c (child_setup):
551 Use execve, not execvp, to preserve environ.

559 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
560 display for sliced images (Bug#10500).

564 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
566 * doc.c (Fdocumentation): Re-add handling of function-documentation,
567 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).

580 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
582 * callproc.c (Fcall_process): Don't misreport vfork failure.
584 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
586 * callproc.c (Fcall_process): Fix vfork portability problems.
587 Do not assume that fd[0], count, filefd, and save_environ survive
588 vfork. Fix bug whereby wrong errno value could be reported for
589 pipe failure. Some minor cleanups, too, as follows. Move buf and
590 bufsize to the context where they're needed. Change new_argv to
591 be of type char **, as this is more convenient and avoids casts.
592 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
593 Now local constants, not macros.
595 2012-11-18 Kenichi Handa <handa@gnu.org>
597 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
598 for the variable "f".

643 2012-11-24 Eli Zaretskii <eliz@gnu.org>
645 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
646 between bpos_covered and bpos_max. This fixes cursor display when
647 several display strings follow each other.
649 * .gdbinit (pgx): If the glyph's object is a string, display the
650 pointer to string data, rather than the value of the string object
651 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
653 * indent.c (Fvertical_motion): If the starting position is covered
654 by a display string, return to one position before that, to avoid
655 overshooting it inside move_it_to. (Bug#12930)
657 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
659 * frame.h (struct frame): Remove display_preempted member

669 * xterm.h (struct x_output): Drop outdated #if 0 code.
670 Use bitfields for explicit_parent, asked_for_visible,
671 has_been_visible and net_wm_state_hidden_seen members.

676 of a literal "/". (Bug#12955)
677 (gl-stamp): Invoke fc.exe directly, not through cmd.
679 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
681 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
682 * dired.c: Assume HAVE_DIRENT_H.
683 (NAMLEN): Remove, replacing with ...
684 (dirent_namelen): New function. All uses changed. Use the GNU macro
685 _D_EXACT_NAMELEN if available, as it's faster than strlen.
686 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
687 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
688 * makefile.w32-in (DIR_H): Remove. All uses replaced with

691 * ndir.h: Rename to ../nt/inc/dirent.h.
692 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
693 Do not include <dirent.h>; no longer needed.

696 2012-11-23 Chong Yidong <cyd@gnu.org>
698 * xftfont.c (xftfont_open): Remove duplicate assignment.
700 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
702 * alloc.c (Fgarbage_collect): Unblock input after clearing
703 gc_in_progress to avoid note_mouse_highlight glitch with GC.
704 * frame.h (FRAME_MOUSE_UPDATE): New macro.
705 * msdos.c (IT_frame_up_to_date): Use it here...
706 * w32term.c (w32_frame_up_to_date): ...here...
707 * xterm.c (XTframe_up_to_date): ...and here...
708 * nsterm.m (ns_frame_up_to_date): ...but not here.
709 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
711 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

718 simplify large 'if' statements.
719 (redisplay_internal): Generalize commonly used
720 'tail' and 'frame' local variables.
722 2012-11-22 Eli Zaretskii <eliz@gnu.org>
724 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
725 with Windows system header.
727 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
729 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
730 * alloc.c: Assume unistd.h exists.
731 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
732 * sysdep.c (get_current_dir_name): Assume getcwd exists.
733 (getwd) [USG]: Remove; no longer needed.

746 * emacs.c (main): Set the G_SLICE environment variable for all
747 Cygwin builds, not just GTK builds. See
748 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
750 2012-11-21 Eli Zaretskii <eliz@gnu.org>
752 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
753 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
754 Define for the MSVC compiler.
756 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
758 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
759 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
760 dostounix_filename. Prevents crashes down the road, because
761 dostounix_filename assumes it gets a unibyte string. Reported by
762 Michel de Ruiter <michel@sentient.nl>, see
763 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
765 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

790 (redisplay_internal): Likewise. Fix indentation.
792 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
794 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
795 (syms_of_eval): Remove corresponding defsubr.
796 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
798 2012-11-19 Daniel Colascione <dancol@dancol.org>
800 * w32fns.c (Fx_file_dialog):
801 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
802 cygwin_convert_file_name*.
804 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
805 Rename cygwin_convert_path* to cygwin_convert_file_name*.
807 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
809 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
811 2012-11-18 Eli Zaretskii <eliz@gnu.org>
813 * w32select.c: Include w32common.h before w32term.h, so that
814 windows.h gets included before w32term.h uses some of its
817 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
819 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
821 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
823 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
825 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).

830 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
831 Needed following 2012-10-20 change. (Bug#12902)
833 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
835 * w32proc.c (waitpid): Remove unused label get_result.
837 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
839 * makefile.w32-in (SYSWAIT_H): New macro.
840 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
841 ($(BLD)/sysdep.$(O)): Update dependencies.
843 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
845 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
846 * callproc.c (relocate_fd): Assume F_DUPFD.
847 * emacs.c, term.c (O_RDWR): Remove.
848 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
849 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
850 * nsterm.m: Assume <fcntl.h> exists.
851 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
852 (create_pty, Fmake_network_process, server_accept_connection)
853 (wait_reading_process_output, init_process_emacs):
855 (wait_reading_process_output): Put in a special case for WINDOWSNT
856 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
857 It's not clear this is needed, but it's a more-conservative change.
858 (create_process): Assume FD_CLOEXEC.
859 (create_process, create_pty): Assume O_NOCTTY.
860 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
861 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
862 Omit if not DOS_NT, since F_GETFL is not defined there.
863 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
864 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
866 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
867 lack it, since gnulib guarantees this.
868 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
870 2012-11-17 Eli Zaretskii <eliz@gnu.org>
872 * w32.c (faccessat): Pretend that directories have the execute bit
873 set. Emacs expects that, e.g., in files.el:cd-absolute.
875 * w32proc.c (create_child): Don't clip the PID of the child
876 process to fit into an Emacs integer, as this is no longer a
878 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
879 reaping only the process specified by PID argument, if that is
880 positive. Use PID instead of dead_child to know which process to
881 reap. Wait for the child to die only if WNOHANG is not in
883 (sys_select): Don't set dead_child.
885 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
886 as it is no longer needed.
888 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
890 (record_child_status_change): Remove the setting of
891 record_at_most_one_child for the !WNOHANG case.
893 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
895 Fix problems in ns port found by static checking.
896 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
897 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
898 not to process group.
899 (ns_select): Use emacs_write, not write, as that's more robust
900 in the presence of signals.
901 (fd_handler:): Check for read errors.
903 2012-11-16 Glenn Morris <rgm@gnu.org>
905 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
907 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
909 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
911 2012-11-16 Eli Zaretskii <eliz@gnu.org>
913 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
914 use the same value of thread handle.
915 (start_timer_thread): If the timer thread exited (due to error),
916 clean up by closing the two handles it used. Duplicate the caller
917 thread's handle here, so it gets duplicated only once, when
918 launching the timer thread. Set priority of the timer thread, not
920 (getitimer): Don't duplicate the caller thread's handle here.
923 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
925 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
928 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
930 Remove no-longer-used pty_max_bytes variable.
931 * process.c (pty_max_bytes): Remove; unused.
932 (send_process): Do not set it.
934 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
936 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
939 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
941 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
942 This follows up on the 2012-09-29 patch that removed indirection
943 for the 'function' field. Reported by Sergey Vinokurov in
944 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
946 2012-11-14 Eli Zaretskii <eliz@gnu.org>
948 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
949 different name, as the MS runtime does not have such a function,
950 and probably never will.) All callers changed. Ignore DIRFD
951 value if PATH is an absolute file name, to match Posix spec
952 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
955 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
957 * xdisp.c (echo_area_display, redisplay_internal):
958 Omit redundant check whether frame_garbaged is set.
960 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
962 Use faccessat, not access, when checking file permissions (Bug#12632).
963 This fixes a bug that has been present in Emacs since its creation.
964 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
965 which must set some sort of record. (Torek's bug report was against
966 a predecessor of GNU Emacs, but GNU Emacs happened to have the
967 same common flaw.) See Torek's Usenet posting
968 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858

983 Test whether directories are accessible, not merely whether they exist.
984 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
985 * fileio.c (check_existing, check_executable, check_writable)
987 Use symbolic names instead of integers for the flags, as they're
989 (check_writable): New arg AMODE. All uses changed.
990 Set errno on failure.
991 (Ffile_readable_p): Use faccessat, not stat + open + close.
992 (Ffile_writable_p): No need to call check_existing + check_writable.
993 Just call check_writable and then look at errno. This saves a syscall.
994 dir should never be nil; replace an unnecessary runtime check
995 with an eassert. When checking the parent directory of a nonexistent
996 file, check that the directory is searchable as well as writable, as
997 we can't create files in unsearchable directories.
998 (file_directory_p): New function, which uses 'stat' on most platforms
999 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1000 (Ffile_directory_p, Fset_file_times): Use it.
1001 (file_accessible_directory_p): New function, which uses a single
1002 syscall for efficiency.
1003 (Ffile_accessible_directory_p): Use it.
1004 * xrdb.c (file_p): Use file_directory_p.
1005 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1006 * lread.c (openp): When opening a file, use fstat rather than
1007 stat, as that avoids a permissions race. When not opening a file,
1008 use file_directory_p rather than stat.
1009 (dir_warning): First arg is now a usage string, not a format.
1010 Use errno. All uses changed.
1011 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1012 that merely introduced a race.
1013 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1014 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1015 and similarly for the other O_* flags.
1016 * w32.c (sys_faccessat): Rename from sys_access and switch to
1017 faccessat's API. All uses changed.
1018 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1019 (magic_db): Rename from magic_file_p.
1020 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1021 char *, so that we don't have to test for file existence
1022 separately from opening the file for reading. This removes a race
1023 fixes a permission-checking problem, and simplifies the code.
1025 (file_p): Remove; no longer needed.
1027 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1029 Omit glyphs initialization at startup.

1035 * xdisp.c (clear_garbaged_frames): Likewise.
1037 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1039 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1040 passed to pint2str and pint2hrstr to be at most the size of the
1041 frame's decode_mode_spec_buffer. This avoids crashes with very
1042 large values of FIELD_WIDTH argument to decode_mode_spec.
1045 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1047 Fix a race with verify-visited-file-modtime (Bug#12863).
1048 Since at least 1991 Emacs has ignored an mtime difference of no
1049 more than one second, but my guess is that this was to work around
1050 file system bugs that were fixed long ago. Since the race is
1051 causing problems now, let's remove that code.
1052 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1053 whose time stamp is off by no more than a second. Insist that the
1054 file time stamps match exactly.
1056 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1058 * frame.h (struct frame): Convert external_tool_bar member to
1059 1-bit unsigned bitfield.

1061 all users are long dead. Adjust comment on mouse_position_hook.
1063 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1065 Simplify by using FOR_EACH_FRAME here and there.
1066 * frame.c (next_frame, prev_frame, other_visible_frames)
1067 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1068 * w32term.c (x_window_to_scroll_bar): Likewise.
1069 * window.c (window_list): Likewise.
1070 * xdisp.c (x_consider_frame_title): Likewise.
1071 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1072 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1073 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1074 * xmenu.c (menubar_id_to_frame): Likewise.
1075 * xselect.c (frame_for_x_selection): Likewise.
1076 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1077 (x_window_to_menu_bar): Likewise.
1078 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1080 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1082 * data.c (Qdefalias_fset_function): Now static.
1084 Another tweak to vectorlike_header change.
1085 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1086 Remove, and replace all uses with ...
1087 (next_in_free_list, set_next_in_free_list):
1088 New functions, which respect C's aliasing rules better.
1090 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1092 * window.c (list4i): Rename from 'quad'. All uses changed.
1093 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1095 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1097 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1098 warning about mixing declarations and code in ISO C90.
1100 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1102 * window.c (Fsplit_window_internal): Set combination limit of
1103 new parent window to t iff Vwindow_combination_limit is t;
1104 fixing a regression introduced with the change from 2012-09-22.
1105 (Fset_window_combination_limit): Fix doc-string.
1107 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1109 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1110 amount when the scroll margins are too large. When scrolling
1111 backwards in the buffer, give up if cannot reach point or the
1112 scroll margin within a reasonable number of screen lines.
1113 Fixes point position in window under scroll-up/down-aggressively when
1114 point is positioned many lines beyond the window top/bottom.
1117 * ralloc.c (relinquish): If real_morecore fails to return memory
1118 to the system, don't crash; instead, leave the last heap
1119 unchanged and return. (Bug#12774)
1121 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1123 * lisp.h (AUTOLOADP): New macro.

1128 (Finteractive_form): Simplify.
1129 (Fquo): Don't insist on having at least 2 arguments.
1130 (Qdefalias_fset_function): New var.
1132 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1134 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1140 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1142 Fix recently introduced crash on MS-Windows (Bug#12839).
1143 * w32term.h (struct scroll_bar): Use convenient header.
1144 (SCROLL_BAR_VEC_SIZE): Remove.
1145 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1147 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1149 Tweak last vectorlike_header change.
1150 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1151 vectorlike object on the free list. This is introduced to avoid
1152 some (but not all) pointer casting and aliasing problems, see
1153 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1154 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1158 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1160 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1161 been removed, so remove them here also.
1163 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1165 * doc.c (Fdocumentation): Handle new property
1166 dynamic-docstring-function to replace the old ad-advice-info.

1170 * fns.c (Qeql, hashtest_eq): Now static.
1172 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1174 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1175 * fns.c (hashfn_eq, hashfn_eql, sxhash):

1186 special hash function containing a comparison that always yields 1.
1188 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1190 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1191 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1192 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1195 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1197 * image.c (xpm_make_color_table_h): Fix compiler error because
1198 make_hash_table changed.

1202 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1204 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1206 Use ad-hoc comparison function for the profiler's hash-tables.
1207 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1208 (make_log): Use them.
1209 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1210 call Fequal any more.

1258 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1259 (Fmake_bool_vector): Likewise.
1260 (struct large_vector): New type to represent allocation unit for
1261 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1262 (large_vectors): Change type to struct large_vector.
1263 (allocate_vector_from_block): Simplify.

1286 * keyboard.c (event_to_kboard): Do not dereference
1287 frame_or_window field of SELECTION_REQUEST_EVENT

1293 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1294 such as Scroll Lock, if the respective keys are treated as
1295 function keys, not as modifiers. This avoids destroying non-ASCII
1296 keyboard input when Scroll Lock is toggled ON. (Bug#12806)

1300 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1302 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1304 Restore some duplicate definitions (Bug#12814).
1305 This undoes part of the 2012-11-03 changes. Some people build
1306 with plain -g rather than with -g3, and they need the duplicate
1307 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1308 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):

1314 to keypad keys (Bug#12816).
1316 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1318 Minor adjustments of recently-changed frame functions.
1319 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1320 known to be a frame (we're in the FRAMEP branch).
1321 * lisp.h (Qframep): Remove decl. frame.h declares this.
1322 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1323 since they're meant for Lisp fixnum values.
1325 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1327 * window.c (Fwindow_combination_limit): Revert to the only
1328 required argument and adjust docstring as suggested in

1387 2012-11-05 Chong Yidong <cyd@gnu.org>
1389 * process.c (wait_reading_process_output): Revert previous change.
1391 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1393 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).

1413 Simplify by assuming __fpending.
1414 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1415 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1416 Do not assume that __fpending's result fits in int.
1418 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1420 Remove EMACS_OUTQSIZE+sleep hack.
1421 * dispnew.c (update_frame_1): Remove hack for terminals slower
1422 than 2400 bps, which throttled Emacs by having it sleep.
1423 This code hasn't worked since at least 2007, when the multi-tty stuff
1424 was added, and anyway those old terminals are long dead.
1425 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1426 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1428 Fix data-loss with --version (Bug#9574).
1429 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1430 as we can't assume that emacs_strerror is initialized, and strerror
1431 is good enough here.
1432 (main): Invoke atexit earlier, to catch earlier instances of
1433 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1435 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1437 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1438 (keyDown): Remap keypad keys to X11 virtual key codes.
1440 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1442 Fix data-loss with --batch (Bug#9574).
1443 * emacs.c: Include <close-stream.h>.
1444 (close_output_streams): New function.
1445 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1446 and handles errors appropriately.
1447 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1450 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1451 The symptom is a diagnostic "GLib-WARNING **: In call to
1452 g_spawn_sync(), exit status of a child process was requested but
1453 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1454 waitpid(), so exit status can't be returned." The diagnostic
1455 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1456 The real bug is a race condition between Emacs and glib: Emacs
1457 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1458 so that glib can't find it. Work around the bug by invoking
1459 waitpid only on subprocesses that Emacs itself creates.
1460 * process.c (create_process, record_child_status_change):
1461 Don't use special value -1 in pid field, as the caller now must
1462 know the pid rather than having the callee infer it.
1463 The inference was sometimes incorrect anyway, due to another race.
1464 (create_process): Set new 'alive' member if child is created.
1465 (process_status_retrieved): New function.
1466 (record_child_status_change): Use it.
1467 Accept negative 1st argument, which means to wait for the
1468 processes that Emacs already knows about. Move special-case code
1469 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1470 processes that have already been waited for, by testing and
1471 clearing new 'alive' member.
1472 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1473 now does this internally.
1474 (handle_child_signal): Let record_child_status_change do all
1475 the work, since we do not want to reap all exited child processes,
1476 only the child processes that Emacs itself created.
1477 * process.h (Lisp_Process): New boolean member 'alive'.
1479 Omit duplicate definitions no longer needed with gcc -g3.
1480 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1481 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1482 Define only as macros. There's no longer any need to also define
1483 these symbols as enums or as constants, since we now assume
1484 gcc -g3 when debugging.
1486 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1488 * lisp.mk: Adjust comments to the fact that term/internal is now
1489 loaded from loadup.el.
1491 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1492 (msdos_fatal_signal): New function.
1493 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1496 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1497 for GCC versions before 4.
1498 (emacs_raise): Define to call msdos_fatal_signal.
1500 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1501 iterator when starting in the middle of a display or overlay
1504 2012-11-03 Chong Yidong <cyd@gnu.org>
1506 * process.c (wait_reading_process_output): Clean up the last
1509 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1511 * process.c (wait_reading_process_output): Avoid a race condition
1512 with SIGIO delivery (Bug#11536).
1514 2012-11-03 Chong Yidong <cyd@gnu.org>
1516 * buffer.c (cursor_type): Untabify docstring.
1518 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1520 * frame.h (struct frame): Drop can_have_scroll_bars member
1521 which is meaningless for a long time. Adjust comments.
1522 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1523 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1525 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1527 * window.c (decode_next_window_args): Update window arg after
1528 calling decode_live_window and so fix crash reported at
1529 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1530 by Juanma Barranquero <lekktu@gmail.com>.
1531 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1532 * font.c (Ffont_at): Likewise.
1534 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1536 * widget.c (resize_cb): New function.
1537 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1538 (EmacsFrameResize): Check if all is up to date before changing frame
1541 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1543 Implement backtrace output for fatal errors on MS-Windows.
1544 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1545 (BACKTRACE_LIMIT_MAX): New macro.
1546 (w32_backtrace): New function.
1547 (emacs_abort): Use w32_backtrace when the user chooses not to
1548 attach a debugger. Update the text of the abort dialog.
1550 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1552 Window-related stuff cleanup here and there.
1553 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1554 Use decode_any_window.
1555 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1556 * xdisp.c (Fformat_mode_line): Likewise.
1557 * font.c (Ffont_at): Use decode_live_window.
1558 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1559 * window.c (decode_next_window_args): Likewise.
1560 (decode_any_window): Remove static.
1561 * window.h (decode_any_window): Add prototype.
1562 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1563 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1566 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1568 Remove pad from struct input_event.
1569 * termhooks.h (struct input_event): Remove padding field.
1571 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1572 member is never cons for a long time. Adjust comment.
1573 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1574 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1575 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1576 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1578 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1580 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1582 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1584 Fix crash when using Emacs as commit editor for git (Bug#12697).
1585 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1586 and it is configured in conf_post.h.
1587 (Fcall_process): Don't invoke both setsid and setpgid; the former
1588 is enough, if it exists.
1589 * callproc.c (Fcall_process, child_setup):
1590 * process.c (create_process): Use setpgid.
1591 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1593 * dispnew.c (init_display): Initialize the foreground group
1594 if we are running a tty display.
1595 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1596 * lisp.h (init_foreground_group): New decl.
1597 * sysdep.c (inherited_pgroup): New static var.
1598 (init_foreground_group, tcsetpgrp_without_stopping)
1599 (narrow_foreground_group, widen_foreground_group): New functions.
1600 (init_sys_modes): Narrow foreground group.
1601 (reset_sys_modes): Widen foreground group.
1603 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1605 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1607 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1609 * minibuf.c (read_minibuf): Restore current buffer since
1610 choose_minibuf_frame calling Fset_frame_selected_window may
1611 change it (Bug#12766).
1613 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1615 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1617 2012-10-30 Kenichi Handa <handa@gnu.org>
1619 * font.c (Ffont_at): If WINDOW is specified and it is not
1620 displaying the current buffer, signal an error.
1622 2012-10-29 Daniel Colascione <dancol@dancol.org>
1624 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1625 In preparation for fixing bug#12739, move these functions from
1628 * coding.h, coding.c: ... to here, and compile them only when
1629 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1630 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1632 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1634 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1635 (timer_loop, getitimer, setitimer): Use it instead of
1636 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1638 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1641 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1643 * nsterm.m (NO_APPDEFINED_DATA): New define.
1644 (last_appdefined_event_data): New variable
1645 (last_appdefined_event): Remove.
1646 (ns_select): Initialize t from last_appdefined_event_data instead
1647 of [last_appdefined_event data1].
1648 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1649 remove last_appdefined_event (Bug#12698).
1651 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1653 * frame.c (x_set_font): Catch internal error.
1655 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1657 Avoid overflow in w32 implementation of interval timers.
1658 When possible, for ITIMER_PROF count only times the main thread
1660 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1661 'volatile ULONGLONG' types. All the other data which was
1662 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1663 (GetThreadTimes_Proc): New typedef.
1664 (w32_get_timer_time): New function, returns a suitable time value
1666 (timer_loop): Enter critical section when accessing ULONGLONG
1667 values of the itimer_data struct, as these accesses are no longer
1668 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1669 Remove unused variable.
1670 (init_timers): Initialize s_pfn_Get_Thread_Times.
1671 (start_timer_thread): Don't assign itimer->caller_thread here.
1672 (getitimer): Assign itimer->caller_thread here.
1673 (setitimer): Always call getitimer to get the value of ticks_now.
1674 (sys_spawnve): Avoid compiler warning about format mismatch.
1676 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1678 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1679 mouse movement events if the menu bar is active. This avoids
1680 producing a busy "hour-glass" cursor by Windows if the mouse
1681 pointer is positioned over a tooltip shown for some menu item.
1683 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1685 Don't assume process IDs fit in int.
1686 * emacs.c (shut_down_emacs) [!DOS_NT]:
1687 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1688 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1689 Use pid_t, not int, to store process IDs, as 'int'
1690 is not wide enough on a few platforms (e.g., AIX and IRIX).
1692 2012-10-23 Kenichi Handa <handa@gnu.org>
1694 The following change is to make face-font-rescale-alist work
1695 correctly for non-ASCII fonts.
1697 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1698 (font_open_for_lface): Handle Vface_font_rescale_alist.
1700 2012-10-23 Chong Yidong <cyd@gnu.org>
1702 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1704 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1706 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1708 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1710 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1713 2012-10-21 Glenn Morris <rgm@gnu.org>
1715 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1717 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1719 Port to OpenBSD 5.1.
1720 * frame.c (Fmouse_position, Fmouse_pixel_position):
1721 * xdisp.c (produce_stretch_glyph):
1722 Declare local vars only when they're needed.
1723 This is clearer and avoids a warning on OpenBSD about unused vars.
1724 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1725 This is safer, and avoids OpenBSD warnings about unused vars.
1726 * keyboard.c (record_menu_key): Remove unnecessary decl.
1727 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1728 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1729 as our definition clashes with OpenBSD's.
1730 * xfaces.c (load_face_colors, check_lface_attrs)
1731 (get_lface_attributes_no_remap, get_lface_attributes)
1732 (lface_fully_specified_p, x_supports_face_attributes_p)
1733 (tty_supports_face_attributes_p, face_fontset, realize_face)
1734 (realize_x_face, realize_tty_face):
1735 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1736 merely Lisp_Object *. This is more informative and avoids
1737 a warning on OpenBSD about accessing beyond an object's size.
1739 2012-10-20 Chong Yidong <cyd@gnu.org>
1741 * lread.c (Fload): Doc fix (Bug#12592).
1743 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1745 * font.c (Ffont_at): Fix previous change.
1747 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1749 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1750 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1753 * alloc.c (NSTATICS): Decrease to 0x800.
1755 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

1760 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1762 * nsterm.m (ns_select): Check writefds before call to
1763 FD_ISSET (Bug#12668).
1765 2012-10-18 Daniel Colascione <dancol@dancol.org>
1767 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1768 (staticpro): If we run out of staticpro slots, die with an
1769 informative error instead of just calling emacs_abort.
1771 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1773 Fix two flaws reported by Dmitry Antipov.
1774 * window.c (Ftemp_output_buffer_show): Remove.
1775 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
1776 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
1778 2012-10-17 Eli Zaretskii <eliz@gnu.org>

1783 ($(BLD)/unexw32.$(O)):
1784 ($(BLD)/fileio.$(O)):
1785 ($(BLD)/dispnew.$(O)): Update dependencies.
1787 * w32term.h (w32_initialize_display_info, initialize_w32_display):
1790 * w32proc.c: Include ctype.h.
1792 * w32.h (init_environment, check_windows_init_file)
1793 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
1794 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
1795 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1796 (sys_link): Add prototypes.
1798 * w32.c: Include w32select.h.
1799 (sys_access, e_malloc, sys_select): Add prototypes.
1800 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
1802 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
1804 * unexw32.c: Include lisp.h and w32.h.
1806 * term.c [WINDOWSNT]: Include w32term.h.
1808 * process.c [WINDOWSNT]: Add prototype of sys_select.
1810 * fileio.c [WINDOWSNT]: Include w32.h.
1812 * dispnew.c [WINDOWSNT]: Include w32.h.
1814 * cygw32.c (Fcygwin_convert_path_to_windows)
1815 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
1816 Lisp_Object values. (Bug#12661)
1818 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
1819 to Lisp_Object. (Bug#12661)
1821 2012-10-17 Kenichi Handa <handa@gnu.org>

1829 reset its buffer pointer to NULL (Bug#12652).
1831 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
1833 Do not verify indirection counters of killed buffers (Bug#12579).
1834 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
1835 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
1837 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
1839 * alloc.c (Fmake_byte_code): Fix typo in comment.
1840 * print.c (print_interval): Define as static to match prototype.
1841 * indent.c (disptab_matches_widthtab, recompute_width_table):
1844 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>

1855 2012-10-15 Martin Rudalics <rudalics@gmx.at>
1857 * window.c (Fwindow_end): Rewrite check whether cached position
1858 can be used (Bug#12600).
1859 (resize_frame_windows, grow_mini_window, shrink_mini_window):
1860 Set windows_or_buffers_changed.
1862 2012-10-15 Daniel Colascione <dancol@dancol.org>
1864 * dbusbind.c: Fix cygw32 build break when compiling with dbus
1865 enabled by undefining the symbol "interface", which the platform
1866 headers define to something incompatible.
1868 2012-10-14 Daniel Colascione <dancol@dancol.org>
1870 * image.c (init_tiff_functions, init_imagemagick_functions)

1880 * gtkutil.c (xg_set_widget_bg): Divide by 65535 (Bug#12612).
1882 2012-10-13 HANATAKA, Shinya <bogytech@gmail.com> (tiny change)
1884 * coding.c (detect_coding): Set coding->id before calling
1887 2012-10-13 Andreas Schwab <schwab@linux-m68k.org>
1889 * fileio.c: Formatting fixes.

1893 Fix some stat-related races.
1894 * fileio.c (Fwrite_region): Avoid race condition if a file is
1895 removed or renamed by some other process immediately after Emacs
1896 writes it but before Emacs stats it. Do not assume that stat (or
1898 * image.c (slurp_file): Resolve the file name with fopen + fstat
1899 rather than stat + fopen.
1900 (pbm_read_file) [0]: Remove unused code with stat race.
1901 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
1902 Remove ineffective code with stat race.
1904 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

1927 * fileio.c (check_existing): New function.
1928 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1929 instead of calling 'stat', when what's needed is to check whether
1930 a file exists. This avoids expensive system calls on MS-Windows.
1933 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1935 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

1982 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
1984 * marker.c (cached_modiff): EMACS_INT, not int.
1986 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
1987 instead of having a wrong decl.

2027 Use unsigned for counter where wraparound-on-overflow is desired,
2028 since unsigned is guaranteed to have that behavior and signed is not.
2029 (read_char): Use ptrdiff_t for string length.
2030 (get_input_pending): Remove first argument, since it was always
2031 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2032 and behave as if it had that value. Return new value of
2033 input_pending. All callers changed.
2034 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2035 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2037 * keymap.c (push_key_description): Omit last arg, which was always 1.
2038 All callers changed.
2040 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
2042 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

2058 Don't include termopts.h.
2060 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2062 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2064 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2066 * commands.h (immediate_quit): Remove duplicate decl.
2068 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2070 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
2072 (nsfont_open): Remove setting of Vfonts_in_cache.
2073 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2075 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2077 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2078 match what GetLastError returns. Explain why the function is
2081 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2082 'is_tooltip_frame', to avoid confusion with its global namesake.
2084 2012-10-08 Daniel Colascione <dancol@dancol.org>
2086 * xdisp.c (start_hourglass): Call w32_note_current_window when
2087 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2088 build that caused Emacs to display the hourglass cursor forever.
2090 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2091 which is broken under remote desktop, calculate the number of
2092 colors available for a display based on the display's number of
2093 planes and number of bits per pixel per plane. (bug#10397).
2095 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2097 * nsfont.m (Vfonts_in_cache): New variable.
2098 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2099 are used. Add cached fonts to Vfonts_in_cache.
2100 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2102 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2104 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2106 (FONT_H): Define after FRAME_H.
2107 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2108 Update dependencies.
2110 * w32term.c: Remove leftover declaration of keyboard_codepage.
2112 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2114 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2115 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2116 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2117 (GLOBAL_SOURCES): Add cygw32.c.
2118 ($(BLD)/unexw32.$(O)):
2120 ($(BLD)/w32console.$(O)):
2121 ($(BLD)/w32fns.$(O)):
2122 ($(BLD)/w32heap.$(O)):
2123 ($(BLD)/w32menu.$(O)):
2124 ($(BLD)/w32proc.$(O)): Add w32common.h.
2126 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2128 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2130 2012-10-08 Daniel Colascione <dancol@dancol.org>
2132 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2133 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2134 accidental message numbering hole. Change other messages to
2137 * w32select.h (HAVE_W32SELECT): Remove.
2139 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2140 w32common.h instead of w32heap.h.
2142 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2143 (get_allocation_unit, get_processor_type, get_w32_major_version)
2144 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2145 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2146 (OS_NT, os_subtype, cache_system_info): Move declarations to
2149 * w32heap.c: Include w32common.h.
2150 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2151 (w32_minor_version, w32_build_number, w32_subtype):
2152 Remove duplicate definitions.
2154 * w32fns.c: Include w32common.h; include w32heap.h only in
2157 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2158 Use `report_file_error' instead of `error' in order to better
2159 inform users of what went wrong. Increase NTGUI_UNICODE file
2160 dialog box file name length to 32k, the maximum allowed by the NT
2163 * w32common.h: New file.
2164 (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 here.
2170 * unexw32.c, unexcw.c: Include w32common.h.
2172 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2173 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2174 to call syms_of_w32select.
2176 * cygw32.h: Remove obsolete EXFUN declarations.
2178 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2180 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2181 of w32inevt.o from SOME_MACHINE_OBJECTS.
2183 2012-10-08 Daniel Colascione <dancol@dancol.org>
2185 * image.c: Permanent fix for JPEG compilation issue --- limit
2186 jpeglib `boolean' redefinition to Cygwin builds.
2188 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2190 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2192 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2195 2012-10-08 Daniel Colascione <dancol@dancol.org>
2197 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2198 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2199 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2200 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2201 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2202 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2203 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2204 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2205 now a supported configuration.
2207 * Makefile.in: consolidate image variables into LIBIMAGE; add
2208 W32_OBJ and W32_LIBS. Compile new files.
2211 (_DebPrint) declare tracing facility for W32 debugging. We need
2212 to unify tracing later.
2214 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2215 unconditional use of W32 Unicode functions. Cygwin runs only on
2216 100% Unicode operating systems.
2218 * cygw32.c: New file. Define Cygwin-specific facilities.
2219 (Fcygwin_convert_path_to_windows)
2220 (Fcygwin_convert_path_from_windows): New user functions for
2221 accessing Cygwin path-munging routines.
2223 * cygw32.h: New file.
2224 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2225 UTF-16LE strings temporarily inside non-Lisp-visible string
2228 (w32_strerror): Just what it says on the tin.
2230 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2231 also run for Cygwin; both systems have the same problem with using
2232 GUI facilities in a forked child. Also call syms_of_cygw32,
2233 syms_of_w32select in correct places.
2235 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2236 needs fork-then-exec for daemon launching.
2238 * font.h: Include frame.h.
2240 * image.c: Use the image library cache machinery only when we're
2241 compiling for native WINDOWSNT; Cygwin can use shared libraries
2242 like any other Unixlike system.
2244 * keyboard.c: Clarify a comment regarding the input loop.
2246 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2247 functions directly instead of trying to detect at runtime that our
2248 host operating system supports them. We make this change for two
2249 reasons: Cygwin lacks support for the multibyte character
2250 conversion functions used by the legacy menu code, and Cygwin
2251 never needs to rely on non-Unicode APIs.
2253 * unexw32.c (hinst): Declare extern.
2255 * w32.c: Change header order;
2256 (w32_strerror): Move to w32fns.c because we need it for
2257 non-WINDOWSNT builds.
2259 * w32.h: Add #error macro to make sure we don't include w32.h for
2260 Cygwin builds. Remove w32select declarations.
2262 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2263 w32fns.c. w32console.c is WINDOWSNT-only.
2265 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2266 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2268 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2269 (w32_major_version, w32_minor_version, w32_build_number)
2270 (os_subtype, sound_type): Define here
2271 (w32_defined_color): Make color parameter const for consistency
2272 with other _defined_color functions.
2273 (w32_createwindow): Unconditionally call w32_init_class instead of
2274 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2275 through the code is complex and unnecessary because class
2276 registration is practically free.
2277 (w32_name_of_message): New EMACSDEBUG-only function.
2278 (Fset_message_beep): Move here
2279 (Fx_open_connection): Require that the display name for Windows be
2280 "w32" for consistency, emacsclient disambiguation, and maybe, one
2281 day, multi-window-system support.
2282 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2283 Cygwin files for W32 GUI facilities, since these clearly don't
2284 expect Cygwin names.
2285 (_DebPrint): Define.
2286 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2287 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2288 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2289 (w32_last_error): Remove.
2291 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2293 * w32heap.c (syspage_mask): Declare here.
2294 (cache_system_info): Remove.
2296 * w32inevt.c (faked_key): Define globally, not statically.
2297 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2298 (w32_console_toggle_lock_key): Move to w32fns.c.
2300 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2302 * w32proc.c (_DebPrint): Move to w32fns.c.
2303 * w32select.c: Include string.h, stdio.h for Cygwin.
2304 * w32select.h: New File.
2306 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2308 (w32_message_fd): New variable. Under Cygwin, holds the file
2309 descriptor the system used to tell us about pending thread
2312 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2313 that prevented compilation under non-WINDOWSNT systems.
2315 (w32_initialize): Open /dev/windows and assign it to
2316 w32_message_fd. Provide w32 feature.
2318 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2319 (WM_EMACS_INPUT_READY): add.
2320 (prepend_msg, w32_message_fd): Declare globally.
2323 (keyboard_handle): Use only when WINDOWSNT.
2324 (notify_msg_ready): New function. Posts a message to the main
2325 thread's message queue under CYGWIN, which wakes up the main
2326 thread from select(2) by making the /dev/windows file descriptor
2327 ready. Under WINDOWSNT, it sets an event the same way the old
2330 (post, prepend_msg): Actually call notify_msg_ready instead of
2331 setting the input event directly.
2333 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2335 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2336 but it still has blocs in it, don't return it to the system,
2337 instead of aborting. (Bug#12402)
2339 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2341 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2343 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2344 MAC_OS_X_VERSION_10_6.
2345 (syms_of_nsterm): Remove comment about Panther and above for
2347 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2348 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2349 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2351 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2352 MAC_OS_X_VERSION_10_4.
2354 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2355 MAC_OS_X_VERSION_10_2.
2357 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.

2372 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2374 Improve sys_siglist detection.
2375 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2376 defined as a macro, as is done in Solaris.
2377 (sys_siglist_entries): New macro.
2378 (save_strsignal): Use it.
2379 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2380 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2382 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2384 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2385 fullscreen/Fullscreen.
2387 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2388 tobar_height is new.
2390 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2391 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2392 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

2405 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2407 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2409 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2411 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2412 that time stamps of directories could also be changed.
2413 Don't request the too broad GENERIC_WRITE, only the more restrictive
2414 FILE_WRITE_ATTRIBUTES access rights.
2416 * fileio.c (Fset_file_times): Special-case ignoring errors for
2417 directories only on MSDOS, not on MS-Windows.
2419 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2421 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2423 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2425 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2426 see whether CreateFile failed.
2428 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2430 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2431 to avoid similar races.
2432 * keyboard.c (pending_signals): Now bool, not int.
2434 Port timers to OpenBSD, plus check for timer failures.
2435 OpenBSD problem reported by Han Boetes.
2436 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2438 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2439 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2440 like OpenBSD, which has timer_settime but does not declare it.
2441 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2442 whether to use itimerspec-related primitives. All uses of
2443 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2445 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2447 * profiler.c (handle_profiler_signal): Fix a malloc race
2448 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2450 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2452 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2454 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2456 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2457 consistent with the change in return value of 'safe_strsignal'.
2459 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2461 Prefer plain 'static' to 'static inline' (Bug#12541).
2462 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2463 (bidi_set_sor_type, bidi_push_embedding_level)
2464 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

2469 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2470 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2471 Now 'static', not 'static inline'.
2473 Count overruns when profiling; change units to ns.
2474 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2475 Give extra weight to samples after overruns, to attempt to count
2476 the time more accurately.
2477 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2478 the underlying primitives nominally do ns.
2479 (Fprofiler_cpu_start): Document the change. Mention that
2480 the sampling intervals are only approximate.
2482 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2484 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2486 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2487 case for the special 0 coding-system.
2489 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2490 (Fmake_overlay): Remove redundant tests.
2491 (fix_start_end_in_overlays): Remove redundant recentering.
2493 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2495 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2496 Update dependencies.
2498 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2500 Fix a malloc race condition involving strsignal.
2501 A signal can arrive in the middle of a malloc, and Emacs's signal
2502 handler can invoke strsignal, which can invoke malloc, which is
2503 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2504 Fix it by altering the signal handler so that it does not invoke
2506 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2507 * process.c (status_message): Use const pointer, in case strsignal
2508 is #defined to safe_strsignal.
2509 * sysdep.c (sys_siglist, init_signals): Always define and
2510 initialize a substitute sys_siglist if the system does not define
2511 one, even if HAVE_STRSIGNAL.
2512 (safe_strsignal): Rename from strsignal. Always define,
2513 using sys_siglist. Return a const pointer.
2514 * syssignal.h (safe_strsignal): New decl.
2515 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2517 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2519 * w32proc.c (timer_loop): Fix code that waits for timer
2520 expiration, to avoid high CPU usage.
2522 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2524 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2525 (sweep_weak_table): Remove redundant prototypes.
2527 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2529 * emacs.c: Move the inclusion of TERM_HEADER after including
2530 windows.h on WINDOWSNT. This avoids compilation problems with
2533 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2535 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2536 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2537 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2538 as the previous version used 'void *'.
2540 * ralloc.c (ROUNDUP): Fix last change.
2541 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2544 * w32proc.c <disable_itimers>: New static flag.
2545 (init_timers): Initialize it to zero, after creating the critical
2546 sections used by the timer threads.
2547 (term_timers): Set to 1 before deleting the critical sections.
2548 (getitimer, setitimer): If disable_itimers is non-zero, return an
2549 error indication without doing anything. Reported by Fabrice
2550 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2551 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2553 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2556 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2557 term_ntproc after all the other bookkeeping, to get timers working
2558 as long as possible.
2560 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2562 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2563 Suggested by Juri Linkov in
2564 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2566 Prefer plain 'static' to 'static inline' (Bug#12541).
2567 With static functions, modern compilers inline pretty well by
2568 themselves; advice from programmers often hurts as much as it helps.
2569 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2570 this change shrinks the text size of the Emacs executable by 1.1%
2571 without affecting CPU significantly in my benchmark.
2572 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2652 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2654 Revert the FOLLOW-SYMLINKS change for file-attributes.
2655 Doing it right would require several changes to Tramp, and there's
2656 not enough time to get that tested before the freeze today.
2657 * dired.c (directory_files_internal, Ffile_attributes):
2660 * frame.c (x_report_frame_params): Port better to wider ints.
2661 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2662 or that pointers can be printed in 15 decimal digits.
2663 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2700 (check_memory_limits): Adjust prototypes of real_morecore and
2701 __morecore to receive argument of type ptrdiff_t. Use size_t for

2781 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
2783 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
2785 * w32.h (init_timers, term_timers): Add prototypes.
2787 2012-09-30 Kenichi Handa <handa@gnu.org>
2789 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
2790 to the buffer relocation which may be caused by ccl_driver.

2826 (EmacsFSWindow): New interface for fullscreen.
2828 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
2830 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
2832 2012-09-30 Chong Yidong <cyd@gnu.org>
2834 * fns.c (Frandom): Doc fix.
2836 2012-09-30 Martin Rudalics <rudalics@gmx.at>

2839 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
2841 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2843 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
2844 Suggested by Eli Zaretskii in
2845 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2847 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2849 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2850 HAVE_TIMER_SETTIME is defined.
2852 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2854 Profiler improvements: more-accurate timers, overflow checks.
2855 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2856 signal.h, setjmp.h. Include systime.h instead.
2857 (saturated_add): New function.
2858 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
2859 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
2860 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
2862 (enum profiler_cpu_running): New enum.
2863 (profiler_cpu_running): Now of that enum type, not bool.
2864 All uses changed to store the new value.
2865 (handle_profiler_signal): Rename from sigprof_handler_1,
2866 for consistency with other handlers. Do not check whether
2867 cpu_log is a hash-table if garbage collecting, since it
2868 doesn't matter in that case.
2869 (deliver_profiler_signal): Rename from sigprof_handler,
2870 for consistency with other handlers.
2871 (setup_cpu_timer): New function, with much of what used to be in
2872 Fprofiler_cpu_start. Check for out-of-range argument.
2873 Prefer timer_settime if available, and prefer
2874 thread cputime clocks, then process cputime clocks, then
2875 monotonic clocks, to the old realtime clock. Use make_timeval
2876 to round more-correctly when falling back to setitimer.
2877 (Fprofiler_cpu_start): Use it.
2878 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2879 Don't assume that passing NULL as the 2nd argument of setitimer
2880 is the same as passing a pointer to all-zero storage.
2881 Ignore SIGPROF afterwards.
2882 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2883 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2884 non-fatal signal handlers. Ignore SIGPROF on startup.
2885 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2886 in profiler.c, since sysdep.c now uses it.
2888 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
2889 Suggested by Eli Zaretskii in
2890 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2942 * character.h (MAYBE_UNIFY_CHAR): Remove.
2943 * charset.c, charset.h (maybe_unify_char): Now static.
2944 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2945 Since this stuff is now private to charset.c, there's no need for
2946 a public macro and no need to inline by hand.
2948 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
2949 Stefan Monnier <monnier@iro.umontreal.ca>

2979 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
2981 Prefer POSIX timers if available.
2982 They avoid a race if the timer is too close to the current time.
2983 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
2984 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

3010 * w32.h (Vlibrary_cache): Do not declare.
3012 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3014 * w32proc.c (sys_signal): Handle all signals defined by the
3015 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3016 handlers for signals supported by Windows. Don't override
3017 term_ntproc as the handler for SIGABRT.
3018 (sigaction): Rewrite to call sys_signal instead of duplicating its
3020 (sys_kill): Improve commentary.
3022 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3023 consistency with a signature of a signal handler. All callers
3025 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3026 install term_ntproc as a signal handler for SIGABRT, as that
3027 should be done by the dumped Emacs.
3029 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3031 * w32select.c (term_w32select): Protect against repeated
3032 invocation by setting clipboard_owner to NULL after calling
3035 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3036 and term_ntproc to their modified signatures.
3038 * character.c (char_string, string_char): Remove calls to

3047 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3049 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3050 when encountering an unknown bytecode.
3052 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3054 image.c, indent.c: Use bool for booleans.

3057 * image.c: Omit unnecessary static decls.
3058 (x_create_bitmap_mask, x_build_heuristic_mask):

3096 Move pid_t related decls out of lisp.h.
3097 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3098 (interruptible_wait_for_termination):
3099 Move these decls from lisp.h to syswait.h, since they use pid_t.
3100 Needed on FreeBSD; see Herbert J. Skuhra in
3101 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3102 * callproc.c: Include syswait.h.

3148 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3150 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3151 fatal_error_backtrace.
3153 * w32proc.c (sys_kill): Undo last change: don't do anything when
3154 invoked to deliver SIGABRT to our own process. This is now
3155 handled by emacs_raise.
3157 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3159 * w32term.c (w32_read_socket): Remove leftover reference to
3160 interrupt_input_pending.
3162 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3164 Do not use SA_NODEFER.
3165 Problem reported by Dani Moncayo in
3166 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3168 * sysdep.c (emacs_abort): Do not reset signal handler.
3169 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3170 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3171 wanted even on POSIXish hosts, and it doesn't work on Windows.
3173 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3175 * xterm.c (x_term_init): Call fixup_locale before and after calling
3176 gtk_init (Bug#12392).
3178 2012-09-23 Chong Yidong <cyd@gnu.org>
3180 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3181 Vdynamic_library_alist.
3183 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3184 (Fgnutls_available_p): Caller changed.
3186 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3187 (Flibxml_parse_xml_region): Likewise.
3189 * dispextern.h (struct image_type): Remove arg from init function.
3191 * image.c (Finit_image_library, lookup_image_type)
3192 (define_image_type): Remove now-unneeded second arg.
3193 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3194 (init_tiff_functions, init_gif_functions, init_svg_functions):
3195 Arglist and w32_delayed_load calling convention changed.
3196 (gs_type): Remove init_gs_functions; there is no such function.
3197 (valid_image_p, make_image): Fix caller to lookup_image_type.
3199 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3201 Simplify and avoid signal-handling races (Bug#12471).
3203 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3204 Avoid recursive loop if there's a fatal error in the function itself.
3205 * atimer.c (pending_atimers):
3206 * blockinput.h: Don't include "atimer.h"; no longer needed.
3207 (interrupt_input_pending): Remove. All uses removed.
3208 pending_signals now counts both atimers and ordinary interrupts.
3209 This is less racy than having three separate pending-signal flags.
3210 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3212 Rename from their upper-case counterparts BLOCK_INPUT,
3213 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3214 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3215 This makes it easier to access volatile variables more accurately.
3216 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3217 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3218 that's more reliable if the code is buggy and sets
3219 interrupt_input_blocked to a negative value. All uses changed.
3220 * atimer.c (deliver_alarm_signal):
3221 Remove. No need to deliver this to the parent; any thread can
3222 handle this signal now. All uses replaced by underlying handler.
3223 * atimer.c (turn_on_atimers):
3224 * dispnew.c (handle_window_change_signal):
3225 * emacs.c (handle_danger_signal):
3226 * keyboard.c (kbd_buffer_get_event):
3227 Don't reestablish signal handler; not needed with sigaction.
3228 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3230 Rework to avoid unnecessary accesses to volatile variables.
3231 (UNBLOCK_INPUT_TO): Now a function.
3232 (totally_unblock_input, unblock_input): New decls.
3233 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3234 (init_data): Remove. Necessary stuff now done in init_signal.
3235 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3236 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3237 (fatal_error_code): Remove; no longer needed.
3238 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3239 it doesn't always backtrace. All uses changed. No need to reset
3240 signal to default, since sigaction and/or die does that for us now.
3241 Use emacs_raise (FOO), not kill (getpid (), FOO).
3242 (main): Check more-accurately whether we're dumping.
3243 Move fatal-error setup to sysdep.c
3244 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3245 * gtkutil.c (xg_get_file_name, xg_get_font):
3246 Remove no-longer-needed signal-mask manipulation.
3247 * keyboard.c, process.c (POLL_FOR_INPUT):
3248 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3249 * keyboard.c (read_avail_input): Remove.
3250 All uses replaced by gobble_input.
3251 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3252 (kbd_buffer_store_event_hold, gobble_input):
3253 (record_asynch_buffer_change) [USABLE_SIGIO]:
3254 (store_user_signal_events):
3255 No need to mess with signal mask.
3256 (gobble_input): If blocking input and there are terminals, simply
3257 set pending_signals to 1 and return. All hooks changed to not
3258 worry about whether input is blocked.
3259 (process_pending_signals): Clear pending_signals before processing
3260 them, in case a signal comes in while we're processing.
3261 By convention callers now test pending_signals before calling us.
3262 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3263 New functions, to support changes to blockinput.h.
3264 (handle_input_available_signal): Now extern.
3265 (reinvoke_input_signal): Remove. All uses replaced by
3267 (quit_count): Now volatile, since a signal handler uses it.
3268 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3269 All callers changed. Block SIGINT only if not already blocked.
3270 Clear sigmask reliably, even if Fsignal returns, which it can.
3271 Omit unnecessary accesses to volatile var.
3272 (quit_throw_to_read_char): No need to restore sigmask.
3273 * keyboard.c (gobble_input, handle_user_signal):
3274 * process.c (wait_reading_process_output):
3275 Call signal-handling code rather than killing ourselves.
3276 * lisp.h: Include <float.h>, for...
3277 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3278 (pending_signals): Now volatile.
3279 (syms_of_data): Now const if IEEE floating point.
3280 (handle_input_available_signal) [USABLE_SIGIO]:
3281 (terminate_due_to_signal, record_child_status_change): New decls.
3282 * process.c (create_process): Avoid disaster if memory is exhausted
3283 while we're processing a vfork, by tightening the critical section
3285 (send_process_frame, process_sent_to, handle_pipe_signal)
3286 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3288 (send_process): No need for setjmp/longjmp any more, since the
3289 SIGPIPE stuff is now gone. Instead, report an error if errno
3291 (record_child_status_change): Now extern. PID and W are now args.
3292 Return void, not bool. All callers changed.
3293 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3294 Remove. All uses removed. This bug should be fixed now in a
3296 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3297 and record the child status change directly. This avoids the
3298 need to futz with the signal mask.
3299 (process_fatal_action): Move here from emacs.c.
3300 (emacs_sigaction_flags): New function, containing
3301 much of what used to be in emacs_sigaction_init.
3302 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3303 caught by emacs, to make races less likely.
3304 (deliver_process_signal): Rename from handle_on_main_thread.
3306 (BACKTRACE_LIMIT_MAX): Now at top level.
3307 (thread_backtrace_buffer, threadback_backtrace_pointers):
3309 (deliver_thread_signal, deliver_fatal_thread_signal):
3310 New functions, for more-accurate delivery of thread-specific signals.
3311 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3312 (deliver_arith_signal): Handle in this thread, not
3313 in the main thread, since it's triggered by this thread.
3314 (maybe_fatal_sig): New function.
3315 (init_signals): New arg DUMPING so that we can be more accurate
3316 about whether we're dumping. Caller changed.
3317 Treat thread-specific signals differently from process-general signals.
3318 Block all signals while handling fatal error; that's safer.
3319 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3321 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3322 Ignore SIGPIPE unless batch.
3323 (emacs_backtrace): Output backtrace for the appropriate thread,
3324 which is not necessarily the main thread.
3325 * syssignal.h: Include <stdbool.h>.
3326 (emacs_raise): New macro.
3327 * xterm.c (x_connection_signal): Remove; no longer needed
3328 now that we use sigaction.
3329 (x_connection_closed): No need to mess with sigmask now.
3330 (x_initialize): No need to reset SIGPIPE handler here, since
3331 init_signals does this for us now.
3333 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3335 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3336 background rect may be larger (Bug#12245).
3338 2012-09-23 Chong Yidong <cyd@gnu.org>
3340 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3342 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3344 * .gdbinit: Just stop at fatal_error_backtrace.
3345 See Stefan Monnier's request in
3346 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3347 Remove no-longer-used query of system type.
3349 2012-09-22 Chong Yidong <cyd@gnu.org>
3351 * search.c (Freplace_match): Doc fix (Bug#12325).
3353 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3355 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3356 (Fline_end_position): Doc fix.
3358 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3360 2012-09-22 Chong Yidong <cyd@gnu.org>
3362 * dispextern.h (struct image_type): Add new slot, storing a type
3363 initialization function.
3365 * image.c (define_image_type): Call the image initializer function
3366 if it is defined. Arguments and return value changed.
3367 (valid_image_p, make_image): Callers changed.
3368 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3369 (gif_type, imagemagick_type, svg_type, gs_type):
3370 Add initialization functions.
3371 (Finit_image_library): Call lookup_image_type.
3372 (CHECK_LIB_AVAILABLE): Macro deleted.
3373 (lookup_image_type): Call define_image_type here, rather than via
3374 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3375 (syms_of_image): Move define_image_type calls for xbm_type and
3376 pbm_type to lookup_image_type.
3378 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3380 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3381 'idle_timers' from here ...
3382 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3383 lists, to avoid infloops when the timer does something stupid,
3384 like reinvoke itself with the same or smaller time-out.
3387 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3389 * window.c (Fsplit_window_internal): Handle only Qt value of
3390 Vwindow_combination_limit separately.
3391 (Qtemp_buffer_resize): New symbol.
3392 (Vwindow_combination_limit): New default value.
3395 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3397 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3398 the new overlay string. (Bug#10159)
3400 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3402 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3403 or that fprintf is async-signal-safe. POSIX doesn't require
3406 2012-09-22 Chong Yidong <cyd@gnu.org>
3408 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3411 2012-09-22 Kenichi Handa <handa@gnu.org>
3413 * composite.c (composition_reseat_it): Handle the case that a
3414 grapheme cluster is not covered by a single font (Bug#12352).
3416 2012-09-21 Chong Yidong <cyd@gnu.org>
3418 * image.c (define_image_type): Avoid adding duplicate types to
3419 image_types (Bug#12463). Suggested by Jörg Walter.
3421 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3423 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3424 (print_load_command_name): Add case LC_DATA_IN_CODE.
3425 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3427 2012-09-21 Glenn Morris <rgm@gnu.org>
3429 * eval.c (Frun_hook_with_args_until_success)
3430 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3432 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3434 * fileio.c (Ffile_selinux_context): Only call freecon when
3435 lgetfilecon succeeded.
3436 (Fset_file_selinux_context): Likewise. (Bug#12444)
3438 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3440 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3441 reordering, locate the cursor by calling set_cursor_from_row; if
3442 that fails, clear the desired glyph matrix before returning a
3443 failure indication to the caller. Fixes leaving garbled display
3444 when fast scrolling with a down-key. (Bug#12403)
3445 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3446 scrolling through multibyte text.
3448 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3450 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3451 calling mark_vectorlike since that's the one that marks the window.
3452 (mark_discard_killed_buffers): Mark the final cdr.
3453 * window.h (struct window): Move prev/next_buffers to the
3454 non-standard fields.
3455 * window.c (make_window): Initialize prev/next_buffers manually.
3457 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3459 Omit unused arg EXPECTED from socket hooks.
3460 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3461 * nsterm.m (ns_term_init):
3462 * termhooks.h (struct terminal.read_socket_hook):
3463 * w32inevt.c (w32_console_read_socket):
3464 * w32term.c (w32_read_socket):
3465 * xterm.c (XTread_socket):
3466 Omit unused arg EXPECTED. All callers changed.
3467 (store_user_signal_events): Return void, not int, since callers no
3468 longer care about the return value. All uses changed.
3470 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3472 * w32gui.h (XParseGeometry): Do not declare.
3474 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3476 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3477 Ignore 'expected'. See Eli Zaretskii in
3478 <http://bugs.gnu.org/12471#8> (last line).
3480 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3481 (XParseGeometry): Now static. Substitute extremal values for
3482 values that are out of range.
3484 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3486 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3488 * nsfns.m (XParseGeometry): Remove.
3489 (Fx_create_frame): Call x_set_offset to correctly interpret
3490 top_pos in geometry.
3492 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3493 (Fx_parse_geometry): If there is a space in string, call
3494 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3496 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3498 * search.c (scan_buffer): Use character positions in calls to
3499 region_cache_forward and region_cache_backward, not byte
3500 positions. (Bug#12196)
3502 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3503 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3505 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3506 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3507 emacs_blocked_malloc, now deleted.
3509 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3511 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3512 The workaround was for improving performance on Solaris 2.4, but
3513 is getting in the way now. Emacs will still work if someone is
3514 still running Solaris 2.4 in a museum somewhere; Sun dropped
3515 support for Solaris 2.4 in 2003.
3516 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3517 * process.c (create_process) [HAVE_WORKING_VFORK]:
3518 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3519 since Emacs no longer uses vfork on that platform.
3521 2012-09-17 Glenn Morris <rgm@gnu.org>
3523 * emacs.c: Use COPYRIGHT.
3525 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3527 Remove configure's --without-sync-input option (Bug#12450).
3528 When auditing signal-handling in preparation for cleaning it up,
3529 I found that SYNC_INPUT has race conditions and would be a real
3530 pain to fix. Since it's an undocumented and deprecated
3531 configure-time option, now seems like a good time to remove it.
3532 Also see <http://bugs.gnu.org/11080#16>.
3533 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3534 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3535 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3536 (malloc_hysteresis):
3537 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3538 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3539 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3540 (dont_register_blocks, bytes_used_when_reconsidered)
3541 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3542 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3543 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3544 Remove. All uses removed.
3545 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3546 implementation, one that depends on whether the new macro
3547 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3549 * atimer.c (run_timers, handle_alarm_signal):
3550 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3551 (handle_async_input, process_pending_signals)
3552 (handle_input_available_signal, init_keyboard):
3553 * nsterm.m (ns_read_socket):
3554 * process.c (wait_reading_process_output):
3555 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3556 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3558 * xterm.c (XTread_socket):
3560 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3561 * eval.c (handling_signal): Remove. All uses removed.
3562 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3563 All uses replaced with the SYNC_INPUT version.
3564 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3566 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3569 * font.c (Ffont_shape_gstring): Remove unused local.
3571 2012-09-16 Glenn Morris <rgm@gnu.org>
3573 * Makefile.in (clean): No longer run nextstep's clean.
3575 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3577 (ns-app): Move here from ns.mk, and simplify.
3578 (clean): Simplify nextstep entry.
3579 * ns.mk: Remove file.
3581 2012-09-17 Kenichi Handa <handa@gnu.org>
3583 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3584 not covert the last few charactes.
3586 2012-09-16 Kenichi Handa <handa@gnu.org>
3588 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3589 here, but just check the validity of glyphs in the glyph-string.
3591 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3593 * window.c (Fwindow_parameter, Fset_window_parameter):
3594 Accept any window as argument (Bug#12452).
3596 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3598 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3599 to ns_term_init to avoid memory leak.
3601 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3602 explicit retain/release.
3603 (ns_term_init): Only allow one display. Initialize outerpool and
3606 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3608 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3609 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3610 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3611 the Microsoft problem in a different way, by altering ../nt/config.nt.
3613 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3628 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3629 by lisp.h. This completes removal of setjmp.h inclusion
3630 erroneously announced in the previous commit. (Bug#12446)
3632 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3635 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3636 not defined as a macro. The latter happens on MS-Windows.
3639 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3641 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3642 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3643 Some instances of '#include <setjmp.h>' removed, if the
3644 only reason for the instance was because "lisp.h" was included.
3645 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3646 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3647 and _longjmp with the new symbols. Emacs already uses _setjmp if
3648 available, so this change affects only POSIXish hosts that have
3649 sigsetjmp but not _setjmp, such as some versions of Solaris and
3650 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3651 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3652 (png_load_body) [HAVE_PNG]:
3653 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3654 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3655 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3656 since PNG requires jmp_buf. This is the only exception to the
3657 general rule that we now use sys_setjmp and sys_longjmp.
3658 This exception is OK since this code does not change the signal
3659 mask or longjmp out of a signal handler.
3661 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3663 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3664 Include "syssignal.h", for 'main_thread'.
3666 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3668 Avoid out-of-range marker position (Bug#12426).
3669 * insdel.c (replace_range, replace_range_2):
3670 Adjust markers before overlays, as suggested by comments.
3671 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3672 Remove redundant check before calling offset_intervals.
3674 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3676 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3677 current buffer (Bug#12387).
3679 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3681 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3683 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3685 Use a more backwards-compatible timer format (Bug#12430).
3686 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3687 vector element, not from the 4th, since PSECS is now at the end.
3688 (Fcurrent_idle_time): Doc fix.
3690 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3692 Function to mark objects and remove killed buffers at once.
3693 * alloc.c (discard_killed_buffers): Rename to ...
3694 (mark_discard_killed buffers) ... new name. Add marking
3695 of remaining objects. Fix comment. Adjust users.
3696 (mark_object): Do not touch frame buffer lists here.
3697 * frame.c (delete_frame): Reset frame buffer lists here.
3699 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3701 Better workaround for GNOME bug when --enable-gcc-warnings.
3702 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3703 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3704 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3706 Simplify SIGIO usage (Bug#12408).
3707 The code that dealt with SIGIO was crufty and confusing, e.g., it
3708 played tricks like "#undef SIGIO" but these tricks were not used
3709 consistently. Simplify mostly by not #undeffing standard symbols,
3710 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3711 or not as we please) rather than "defined SIGIO" (standard symbol
3712 that we probably shouldn't #undef).
3713 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3714 Modules that need it can include it.
3715 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3716 * dispextern.h (ignore_sigio): New decl.
3717 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3718 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3719 * emacs.c (shut_down_emacs):
3720 * keyboard.c (kbd_buffer_store_event_hold):
3721 Use ignore_sigio rather than invoking 'signal' directly.
3722 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3724 (FIONREAD, SIGIO): Do not #undef.
3725 (tty_read_avail_input): Use #error rather than a syntax error.
3726 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3727 for I_PIPE, used by SETUP_SLAVE_PTY.
3728 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3729 * sysdep.c (croak): Remove; no longer needed. This bit of
3730 temporary code, with Fred N. Fish's comment that it's temporary,
3731 has been in Emacs since at least 1992!
3732 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3733 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3734 * syssignal.h (croak): Remove decl.
3735 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3736 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3737 now that we're termios-only.
3738 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3739 * term.c (dissociate_if_controlling_tty): Use #error rather than
3742 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3743 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3744 to work around GNOME bug 683906.
3745 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3746 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3747 This works around GCC bug 54561.
3749 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3751 More fixes for 'volatile' and setjmp/longjmp.
3752 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3753 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3754 (png_load_body) [HAVE_PNG]:
3755 (jpeg_load_body) [HAVE_JPEG]:
3756 New function, with most of the old parent function's body.
3757 (png_load) [HAVE_PNG]:
3758 (jpeg_load) [HAVE_JPEG]:
3759 Invoke the new function, to avoid longjmp munging our locals.
3760 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3761 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3762 longjmp is passed 2, as the C standard doesn't guarantee this.
3763 Instead, store the failure code into mgr->failure_code.
3765 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3767 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3768 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3769 (syms_of_keyboard): Remove support for unread-command-char.
3771 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3773 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3774 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3775 violation. (Bug#12426)
3777 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3779 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3781 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3783 * eval.c: Add `inhibit-debugger'.
3784 (Qinhibit_debugger): New symbol.
3785 (call_debugger): Bind it instead of Qdebug_on_error.
3786 (maybe_call_debugger): Test Vinhibit_debugger.
3787 (syms_of_eval): Define inhibit-debugger.
3788 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3789 (syms_of_xdisp): Remove inhibit-debug-on-message.
3791 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3793 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3794 If a nonvolatile local variable is written before a _longjmp to
3795 the frame containing the variable, and is read after the _longjmp,
3796 the value read is indeterminate. Some local variables of type
3797 'struct handler' and 'struct catchtag' are used in this way, so
3798 mark each of their slots as volatile if the slot can be set before
3799 _longjmp and read afterwards.
3800 * lisp.h (struct handler): var and chosen_clause are now volatile.
3801 (struct catchtag): val, next, and pdlcount are now volatile.
3803 * bidi.c (bidi_push_it, bidi_pop_it):
3804 * fns.c (copy_hash_table):
3805 * image.c (define_image_type):
3806 * keyboard.c (kbd_buffer_store_event_hold):
3807 * process.c (Fprocess_send_eof):
3808 * xfaces.c (x_create_gc) [HAVE_NS]:
3809 * xgselect.c (xg_select):
3810 Prefer assignment to memcpy when either will do.
3812 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3813 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3814 time an item is removed. No need to mark this function 'inline';
3815 the compiler knows better than we do.
3817 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3819 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3820 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3821 to change_frame_size (Bug#12388).
3822 (windowDidResize:): Pass YES to updateFrameSize.
3824 * nsterm.h: Add delay parameter to updateFrameSize.
3826 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3828 Discard killed buffers from deleted window and frame objects.
3829 This reduces an amount of references to killed buffers and
3830 helps GC to reclaim them faster.
3831 * alloc.c (discard_killed_buffers): New function.
3832 (mark_object): Use it for deleted windows and frames.
3833 (mark_object): If symbol's value is set up for a killed buffer
3834 or deleted frame, restore its global binding.
3835 * data.c (swap_in_global_binding): Add GC notice.
3836 (swap_in_symval_forwarding): Use convenient set_blv_where.
3837 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3838 * window.h: ... to here.
3840 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3842 Convenient macro to check whether the buffer is live.
3843 * buffer.h (BUFFER_LIVE_P): New macro.
3844 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3845 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3847 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3849 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3850 composition cases (Bug#12364).
3852 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3853 overhang of succeeding glyphs overlapping box cursor.
3855 * w32term.c (x_draw_glyph_string): Likewise.
3857 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3859 Simplify, document, and port floating-point (Bug#12381).
3860 The porting part of this patch fixes bugs on non-IEEE platforms
3861 with frexp, ldexp, logb.
3862 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3864 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3865 support, by removing commented-out code and briefly listing the
3866 C89 functions excluded. The commented-out stuff was confusing
3867 maintenance, e.g., we thought we needed cbrt but it was commented out.
3868 (logb): Remove decl; no longer needed.
3869 (isfinite): New macro, if not already supplied.
3870 (isnan): Don't replace any existing macro.
3871 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3872 are present on all C89 platforms.
3873 (Ffrexp): Do not special-case zero, as frexp does the right thing
3875 (Flogb): Do not use logb, as it doesn't have the desired meaning
3876 on hosts that use non-base-2 floating point. Instead, stick with
3877 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3878 frexp, to avoid getting an unspecified result.
3880 * xdisp.c (Qinhibit_debug_on_message): Now static.
3882 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3884 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3885 NSBezierPath (Bug#12131).
3887 2012-09-10 Chong Yidong <cyd@gnu.org>
3889 * fns.c (Fdelq, Fdelete): Doc fix.
3891 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3893 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3894 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3896 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3898 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3899 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3902 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3904 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3905 left fringe if the window has a left margin. This avoids leaving
3906 traces of the cursor because its leftmost pixel is not drawn over.
3908 * dispnew.c (update_window_line): When the left margin area of a
3909 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3910 that screen line. (Bug#12277)
3912 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3914 Assume C89 or later for math functions (Bug#12381).
3915 This simplifies the code, and makes it a bit smaller and faster,
3916 and (most important) makes it easier to clean up signal handling
3917 since we can stop worring about floating-point exceptions in
3918 library code. That was a problem before C89, but the problem
3919 went away many years ago on all practical Emacs targets.
3920 * data.c, image.c, lread.c, print.c:
3921 Don't include <math.h>; no longer needed.
3922 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3923 might be autoconfigured, as that never happens.
3925 * doprnt.c (DBL_MAX_10_EXP):
3926 * print.c (DBL_DIG):
3927 Remove. C89 or later always defines these.
3928 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3929 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3930 (arith_error, domain_error, domain_error2):
3931 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3932 no longer needed -- we simply return what C returns. All uses removed.
3933 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3935 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3936 Remove. All uses expanded, as these macros are no longer used
3937 more than once and are now more trouble than they're worth.
3938 (Ftan): Use tan, not sin / cos.
3939 (Flogb): Assume C89 frexp.
3940 (fmod_float): Assume C89 fmod.
3941 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3942 (init_floatfns): Remove. All uses removed.
3944 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3946 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3947 compositeToPoint for OSX < 10.6 (Bug#12390).
3949 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3951 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3952 This produces more-accurate results.
3954 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3956 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3957 changes (Bug#12088).
3959 2012-09-08 Chong Yidong <cyd@gnu.org>
3961 * syntax.c (Fstring_to_syntax): Doc fix.
3963 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3965 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3966 in the internal border.
3967 (x_set_window_size): Remove static variables and their usage.
3968 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3969 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3970 Remove fringe/internal border adjustment (Bug#11052).
3971 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3972 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3973 (ns_fix_rect_ibw): Remove.
3974 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3975 (ns_dumpglyphs_box_or_relief): Ditto.
3976 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3978 (ns_dumpglyphs_image): Ditto.
3979 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3981 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3982 their usage. Add fringe_extended_p and its use as in other terms.
3983 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3984 scroll bar was removed.
3985 (updateFrameSize): New function.
3986 (windowDidResize): Move code to updateFrameSize and call it.
3988 * nsterm.h (EmacsView): Add updateFrameSize.
3990 2012-09-07 Chong Yidong <cyd@gnu.org>
3992 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3994 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3996 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3998 More signal-handler cleanup (Bug#12327).
3999 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4000 Problem introduced when merging patches. Noted by Eli Zaretskii in
4001 <http://bugs.gnu.org/12327#67>.
4002 * floatfns.c: Comment fix.
4003 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4004 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4005 and anyway the declaration is harmless even if SIGDANGER is not defined.
4006 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4007 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4008 source files not surprisingly expected syssignal.h to define, or
4009 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4010 Include <sys/ioctl.h>, for FIONREAD.
4011 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4012 This eliminates a problem whereby other files mysteriously had
4013 to include "syssignal.h" before including "systty.h" if they
4014 wanted to use "#ifdef SIGIO".
4016 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4018 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4020 * w32.c (sigemptyset): Empty the set.
4021 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4023 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4025 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4027 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4028 (mark_object): Likewise for frame objects.
4030 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4032 * syssignal.h (handle_on_main_thread): Always declare,
4033 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4034 This ports to platforms without HAVE_PTHREAD.
4036 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4038 Signal-handler cleanup (Bug#12327).
4039 Emacs's signal handlers were written in the old 4.2BSD style with
4040 sigblock and sigmask and so forth, and this led to some
4041 inefficiencies and confusion. Rewrite these to use
4042 pthread_sigmask etc. without copying signal sets around. Also,
4043 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4044 'signal', and instead use functions that do not attempt to take
4045 over the system name space. This patch causes Emacs's text
4046 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4047 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4048 Do not include <signal.h> or "syssignal.h", as these
4049 modules do not use signals.
4050 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4051 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4052 Do not include <signal.h>, as "syssignal.h" does that for us now.
4053 * atimer.c (sigmask_atimers): New function.
4054 (block_atimers, unblock_atimers): New functions,
4055 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4057 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4058 no longer needed here.
4059 * emacs.c (main): Inspect existing signal handler with sigaction,
4060 so that there's no need to block and unblock SIGHUP.
4061 * sysdep.c (struct save_signal): New member 'action', replacing
4062 old member 'handler'.
4063 (save_signal_handlers, restore_signal_handlers):
4064 Use sigaction instead of 'signal' to save and restore.
4065 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4066 New function. All users of 'signal' modified to use set_sighandler
4067 if they're writeonly, and to use sys_signal if they're read+write.
4068 (emacs_sigaction_init, forwarded_signal): New functions.
4069 (sys_signal): Remove. All uses replaced by calls to sigaction
4070 and emacs_sigaction_init, or by direct calls to 'signal'.
4071 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4072 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4073 all uses replaced by pthread_sigmask etc. calls.
4074 * syssignal.h: Include <signal.h>.
4075 (emacs_sigaction_init, forwarded_signal): New decls.
4076 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4077 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4078 (sigmask, sys_sigmask): Remove; no longer needed.
4079 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4080 (sigblock, sigunblock, sigfree):
4081 (sigsetmask) [!defined sigsetmask]:
4082 Remove. All uses replaced by pthread_sigmask.
4083 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4084 no longer need to be replaced, and its typical old uses
4085 are now done via emacs_sigaction_init and sigaction.
4086 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4087 (sys_sigdel): Remove; unused.
4088 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4090 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4092 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4093 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4095 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4097 Explicitly mark buffer_defaults and buffer_local_symbols.
4098 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4099 mark_local_symbols here.
4100 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4101 since special buffers aren't marked here any more.
4102 (allocate_buffer): Chain new buffer with all_buffers here...
4103 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4105 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4106 (syms_of_buffer): Remove staticpro of the above.
4107 (init_buffer_once): Set names for buffer_defaults and
4108 buffer_local_symbols.
4110 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4112 Use bool for booleans in font-related modules.
4113 * font.c (font_intern_prop, font_style_to_value)
4114 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4115 (generate_otf_features, font_check_otf_features, font_check_otf)
4116 (font_match_p, font_list_entities, font_at):
4117 * fontset.c (fontset_id_valid_p, reorder_font_vector
4118 (fontset_find_font, Fset_fontset_font)
4119 (face_suitable_for_char_p) [0]:
4120 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4121 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4122 (m17n_flt_initialized, ftfont_shape_by_flt):

4124 * nsfont.m (nsfont_draw):
4125 * w32font.c (w32font_draw):
4126 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4127 Use bool for booleans.
4128 * font.h: Adjust to above API changes.
4129 (struct font, struct font_driver, struct font_driver_list):
4130 Use bool for booleans.
4131 (struct font): Remove useless member encoding_type.
4133 * fontset.c, xftfont.c: Omit unnecessary static decls.
4135 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4137 * alloc.c (mark_object): Revert window marking code
4138 since it's unsafe for the Fset_window_configuration.
4140 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4142 Fix race conditions with signal handlers and errno (Bug#12327).
4143 Be more systematic about preserving errno whenever a signal
4144 handler returns, even if it's not in the main thread. Do this by
4145 renaming signal handlers to distinguish between signal delivery
4146 and signal handling. All uses changed.
4147 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4148 * data.c (deliver_arith_signal): Rename from arith_error.
4149 * dispnew.c (deliver_window_change_signal): Rename from
4150 window_change_signal.
4151 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4152 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4153 * keyboard.c (deliver_input_available_signal): Rename from
4154 input_available_signal.
4155 (deliver_user_signal): Rename from handle_user_signal.
4156 (deliver_interrupt_signal): Rename from interrupt_signal.
4157 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4158 (deliver_child_signal): Rename from sigchld_handler.
4159 * atimer.c (handle_alarm_signal):
4160 * data.c (handle_arith_signal):
4161 * dispnew.c (handle_window_change_signal):
4162 * emacs.c (handle_fatal_signal, handle_danger_signal):
4163 * keyboard.c (handle_input_available_signal):
4164 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4165 * process.c (handle_pipe_signal, handle_child_signal):
4166 New functions, with the actual signal-handling code taken from the
4167 original respective signal handlers, sans the sporadic attempts to
4168 preserve errno, since that's now done by handle_on_main_thread.
4169 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4170 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4171 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4173 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4174 Move initialization of main_thread to sysdep.c's init_signals.
4175 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4176 our usage, and simplifies the mainline code.
4177 (record_child_status_change): New static function, as a helper
4178 for handle_child_signal, and with most of the old child handler's
4180 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4181 (handle_child_signal): Use the above.
4182 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4183 Moved here from emacs.c.
4184 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4185 code moved here from emacs.c's main function.
4186 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4187 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4188 This lets callers save and restore errno properly.
4190 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4192 Remove redundant or unused things here and there.
4193 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4194 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4195 * editfns.c (Fcompare_buffer_substrings): Likewise.
4196 * frame.h (struct terminal, struct font_driver_list):
4197 Remove redundant declarations.
4198 * window.h (Qleft, Qright): Likewise.
4200 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4202 Do not mark objects from deleted buffers, windows and frames.
4203 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4204 (mark_object): Likewise for windows and frames.
4206 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4208 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4209 buffer_defaults and buffer_local_symbols as valid objects.
4210 Return special value to denote them.
4212 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4214 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4215 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4216 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4217 (file_name_absolute_p, Fsubstitute_in_file_name):
4218 (check_executable, check_writable, Ffile_accessible_directory_p)
4219 (Fset_file_selinux_context, Fdefault_file_modes)
4220 (Finsert_file_contents, choose_write_coding_system)
4221 (Fwrite_region, build_annotations, a_write, e_write)
4223 * filelock.c (boot_time_initialized, get_boot_time)
4224 (get_boot_time_1, lock_file_1, within_one_second):
4225 * floatfns.c (in_float):
4226 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4227 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4228 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4229 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4230 * window.c (compare_window_configurations):
4231 Use bool for booleans.
4232 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4233 (Fdefault_file_modes): Now mode_t, not int, for modes.
4234 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4235 (internal_delete_file): Now returns void, not a (boolean) int,
4236 since nobody was looking at the return value.
4237 * lisp.h, window.h: Adjust to above API changes.
4239 * xdisp.c (set_message): Simplify and reindent last change.
4241 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4243 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4245 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4247 * eval.c (call_debugger): Make the function non-static so that we
4248 can call it from set_message.
4250 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4251 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4253 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4255 Give more-useful info on a fatal error (Bug#12328).
4256 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4257 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4258 of doing the work ourselves.
4259 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4260 do most of the work.
4261 (fatal_error_backtrace): New function, taken from the guts
4262 of the old fatal_error_signal, but with a new option to output
4264 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4265 info about the signal than just its number.
4266 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4267 * sysdep.c: Include <execinfo.h>
4268 (emacs_backtrace): New function, taken partly from the previous
4269 code of the 'die' function.
4270 (emacs_abort): Call fatal_error_backtrace rather than abort.
4272 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4274 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4275 eager (load-time) macro-expansion.
4276 * lisp.mk (lisp): Add macroexp.
4278 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4280 Simplify redefinition of 'abort' (Bug#12316).
4281 Do not try to redefine the 'abort' function. Instead, redo
4282 the code so that it calls 'emacs_abort' rather than 'abort'.
4283 This removes the need for the NO_ABORT configure-time macro
4284 and makes it easier to change the abort code to do a backtrace.
4285 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4286 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4287 Remove; sysdep.c's emacs_abort now takes its place.
4288 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4289 'abort' changed to use 'emacs_abort'.
4290 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4291 (abort) [!defined abort]: Rename to ...
4292 (emacs_abort): ... new name.
4293 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4294 the place of the old 'abort' in emacs.c.
4295 * w32.c, w32fns.c (abort): Do not #undef.
4296 * w32.c (emacs_abort): Rename from w32_abort.
4298 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4300 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4301 offsets[j].dv, since the y axis of the screen coordinates points
4302 down, while the y axis of the font definition coordinates points
4303 up. This fixes display of Arabic diacritics such as KASRA and
4304 KASRATAN. (Bug#11860)
4306 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4308 Be more systematic about _setjmp vs setjmp.
4309 * alloc.c (test_setjmp, mark_stack):
4310 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4311 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4312 (png_load, my_error_exit, jpeg_load):
4313 * process.c (send_process_trap, send_process):
4314 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4315 The underscored versions are up to 30x faster on some hosts.
4316 Formerly, the code used setjmp+longjmp sometimes and
4317 _setjmp+_longjmp at other times, with no particular reason to
4318 prefer setjmp+longjmp.
4320 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4322 Fix minor problem found by static checking.
4323 * buffer.c (Fdelete_all_overlays): Return nil.
4325 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4327 * buffer.c (Fdelete_all_overlays): New function.
4329 2012-09-03 Chong Yidong <cyd@gnu.org>
4331 * gtkutil.c: Add extern decl for Qxft.
4333 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4335 * emacs.c, eval.c: Use bool for boolean.
4336 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4337 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4338 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4339 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4340 (main, decode_env_path, Fdaemon_initialized):
4341 * eval.c (call_debugger, Finteractive_p, interactive_p):
4342 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4343 (maybe_call_debugger, Fbacktrace):
4344 * process.c (read_process_output, exec_sentinel):
4345 Use bool for booleans.
4346 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4347 All callers changed.
4348 * eval.c (interactive_p): Omit always-true boolean argument
4349 EXCLUDE_SUBRS_P. All callers changed.
4350 * dispextern.h, lisp.h: Reflect above API changes.
4351 * firstfile.c (dummy): Use the address of 'main', whose signature
4352 won't change, instead of the address of 'initialize', whose
4353 signature just changed from int to bool.
4354 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4355 * msdos.c (fatal_error_in_progress): ... from here.
4356 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4358 (redisplay_internal, unwind_redisplay): Simply clear
4359 REDISPLAYING_P when unwinding, instead of saving its previous,
4360 always-false value and then restoring it.
4362 Clean up some extern decls.
4363 Mostly, this hoists extern decls out of .c files and into .h files.
4364 That way, we're more likely to catch errors if the interfaces change.
4365 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4366 declare xg_mark_data.
4367 * dispextern.h (x_frame_parm_handlers):
4369 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4370 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4371 (Qultra_bold, Qoblique, Qitalic):
4372 Move extern decl here from .c file.
4373 * alloc.c (xg_mark_data) [USE_GTK]:
4375 * eval.c (Qlexical_binding):
4376 * fns.c (time) [!HAVE_UNISTD_H]:

4382 * process.c (QCfamily, QCfilter):
4383 * widget.c (free_frame_faces):
4384 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4385 * xfont.c (x_clear_errors):
4386 * xterm.c (x_frame_parm_handlers):
4387 Remove now-redundant extern decls.
4388 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4389 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4391 * xfaces.c: Remove unnecessary static decls.
4392 * xterm.c (updating_frame): Remove decl of nonexistent object.
4394 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4395 when building globals.h, as the objects that are not built on
4396 this host are not needed to compile C files on this host.
4398 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4400 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4402 * frame.h: Add missing prototype for x_wm_set_size_hint.
4404 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4408 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4409 (Fsubstitute_command_keys):

4414 (make_buffer_string, make_buffer_string_both)
4415 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

4429 Use bool for boolean.
4430 * intervals.h, lisp.h, systime.h: Reflect above API changes.

4438 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4440 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4441 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

4446 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4448 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4450 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4451 more than one grapheme cluster passed to the shaper: compute the
4452 offset adjustment values separately for each cluster. (Bug#11860)
4454 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4455 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4456 about implicit conversions from integer to pointer.
4458 2012-09-01 Daniel Colascione <dancol@dancol.org>
4460 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4461 system used too early.
4463 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4465 Better seed support for (random).
4466 * emacs.c (main): Call init_random.
4467 * fns.c (Frandom): Set the seed from a string argument, if given.
4468 Remove long-obsolete Gentzel cruft.

4475 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
4476 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,

4478 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4479 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
4480 all of which have been moved to common code.
4482 * xfaces.c: Include TERM_HEADER instead of listing all possible
4483 window-system headers.
4485 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

4489 directly accessing frame internals.
4491 * w32font.h: Include font.h. Define syms_of_w32font and
4494 * process.c: Include TERM_HEADER instead of listing all possible
4495 window-system headers.
4497 * nsterm.h: Remove declarations now in frame.h.
4498 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
4500 * menu.c: Include TERM_HEADER instead of listing all possible
4501 window-system headers.
4503 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4506 * keyboard.c: Include TERM_HEADER instead of listing all possible
4507 window-system headers.
4509 * image.c: Include TERM_HEADER instead of listing all possible
4510 window-system headers. Declare Vlibrary_cache when compiling for
4513 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4514 window system declarations.
4516 * frame.h: Move common functions here: set_frame_menubar,
4517 x_set_window_size, x_sync, x_get_focus_frame,
4518 x_set_mouse_position, x_set_mouse_pixel_position,
4519 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4539 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
4540 the current window system; include in list of objects to link into
4543 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4545 Remove mark_ttys function and fix tty_display_info initialization.
4546 * lisp.h (mark_ttys): Remove prototype.
4547 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4548 to mark_ttys because all possible values of 'top_frame' slot are
4549 the frames which are reachable from Vframe_list.
4550 * term.c (mark_ttys): Remove.
4551 (init_tty): Safely initialize 'top_frame' slot with Qnil.
4553 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4555 Change struct frame bitfields from unsigned char to unsigned.
4556 * frame.h (struct frame): Change type of 'display_preempted',
4557 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
4558 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
4559 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
4560 bitfields from unsigned char to unsigned.
4562 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4564 Remove unused member of struct x_output and struct w32_output.
4565 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
4566 * w32term.h (struct w32_output): Likewise.
4568 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
4570 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4571 does not become zero (Bug#12234).
4573 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
4575 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4576 for GCC 4.7.1 x86-64.
4578 2012-08-30 Glenn Morris <rgm@gnu.org>
4580 * lread.c (init_lread): For out-of-tree builds, only add the
4581 source directory's site-lisp dir to the load-path if it exists,
4582 consistent with in-tree builds. (Bug#12302)
4584 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
4586 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
4587 button_values to NULL. Call setStykeMask so dialogs get a close button.
4588 (windowShouldClose:): Set window_closed.
4589 (dealloc): New member, free button_values.
4590 (process_dialog:): Make member function. Remove window argument,
4591 replace window with self. Count buttons and allocate and store values
4593 (addButton:value:row:): value is int with the name tag. Call setTag
4594 with tag. Remove return self, declare return value as void.
4595 (addString:row:): Remove return self, declare return value as void.
4596 (addSplit): Remove return self, declare return value as void.
4597 (clicked:): Remove return self, declare return value as void.
4598 Set dialog_return to button_values[seltag]. Code formatting change.
4599 (initFromContents:isQuestion:): Adjust call to process_dialog.
4600 Code formatting change.
4601 (timeout_handler:): Set timer_fired to YES.
4602 (runDialogAt:): Set timer_fired to NO.
4603 Handle click on close button as quit.
4605 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4606 Add window_closed and button_values. Add void as return value for
4607 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4608 Add process_dialog as new member.
4610 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4612 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
4613 is not one of the heaps we manage. (Bug#12242)
4615 2012-08-28 Glenn Morris <rgm@gnu.org>
4617 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
4619 2012-08-28 Martin Rudalics <rudalics@gmx.at>
4621 * window.c (Fset_window_configuration): Remove handling of
4622 auto-buffer-name window parameter. Install revision of reverted
4625 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4627 Do not allow to set major mode for a dead buffer.
4628 * buffer.c (Fset_buffer_major_mode): Signal an error
4629 if the buffer is dead.
4630 (Fother_buffer, other_buffer_safely): Remove redundant
4633 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4635 Always use set_buffer_if_live to restore original buffer at unwind.
4636 * buffer.h (record_unwind_current_buffer): New function.
4637 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
4638 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
4639 * undo.c, window.c: Adjust users.
4640 * buffer.c (set_buffer_if_live): Fix comment.
4642 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4644 Fix usage of set_buffer_internal.
4645 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
4646 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
4647 * coding.c (decode_coding): Omit redundant test.
4648 * fileio.c (decide_coding_unwind): Likewise.
4649 * fns.c (secure_hash): Likewise.
4650 * insdel.c (modify_region): Likewise.
4651 * keyboard.c (command_loop_1): Likewise.
4652 * print.c (PRINTFINISH): Likewise.
4653 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
4655 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

4675 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
4676 and remove last int (actually boolean) argument, which was always 0.
4677 All callers changed.
4678 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
4679 * dispextern.h (struct composition_it): Use bool for boolean.
4680 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
4681 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
4682 * dired.c (file_name_completion):
4683 Use bool for boolean. (This was missed in an earlier change.)
4685 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4687 * window.c (Fset_window_configuration): Revert first part of
4690 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
4692 * nsterm.h (NSPanel): New class variable dialog_return.
4694 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
4695 Initialize dialog_return.
4696 (windowShouldClose:): Use stop instead of stopModalWithCode.
4697 (clicked:): Ditto, and also set dialog_return (Bug#12258).
4698 (timeout_handler:): Use stop instead of abortModal. Send a dummy
4700 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

4715 Use bool for booleans.
4716 * dired.c (file_name_completion):
4717 * process.h (fd_callback):
4718 Omit int (actually boolean) argument. It wasn't being used.
4720 * composite.h, lisp.h: Reflect above API changes.

4744 * fileio.c (Finsert_file_contents):
4745 Use bool for booleans.
4746 * coding.h, lisp.h: Reflect above API changes.
4747 * coding.c: Remove unnecessary static function decls.
4748 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4749 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4750 not a boolean 'int', since callers never look at the return value.
4751 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
4752 * coding.h (decoding_buffer_size, encoding_buffer_size)
4753 (emacs_mule_string_char): Remove unused extern decls.
4754 (struct iso_2022_spec, struct coding_system):
4755 Use 'unsigned int : 1' for boolean fields, since there's more than one.
4756 (struct emacs_mule_spec): Remove unused field 'full_support'.
4757 All initializations removed.
4758 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
4760 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4762 Fix spare memory change (Bug#12286).
4763 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4764 (valid_lisp_object_p): Likewise.
4766 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4768 * window.c (Fset_window_configuration): Record any window's old
4769 buffer if it's replaced (see Bug#8789). If the new current
4770 buffer doesn't appear in the selected window, go to its old
4773 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4775 Special MEM_TYPE_SPARE to denote reserved memory.
4776 * alloc.c (enum mem_type): New memory type.
4777 (refill_memory_reserve): Use new type for spare memory.
4778 This prevents live_cons_p and live_string_p from incorrect
4779 detection of uninitialized objects from spare memory as live.
4781 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4784 * Makefile.in (.PHONY): versioclean -> versionclean.
4786 Remove unused external symbols.
4787 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
4788 * window.c (Qwindow_valid_p, decode_valid_window):
4789 Now static, not extern.
4790 * data.c (Qinterval): Remove; unused.
4791 (syms_of_data): Do not define 'interval'.
4792 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
4793 * window.h (decode_valid_window):
4796 * character.c, charset.c, chartab.c: Use bool for booleans.

4806 (char_table_set_range, optimize_sub_char_table)
4807 (map_sub_char_table):
4808 Use bool for boolean.
4809 * character.c (str_to_unibyte): Omit last boolean argument; it was
4810 always 0. All callers changed.
4811 * character.h, charset.h: Adjust to match previous changes.
4812 * character.h (char_printable_p): Remove decl of nonexistent function.
4813 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4814 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4815 are all boolean, so make them single-bit bitfields.
4817 * lisp.h (ASET): Remove attempt to detect side effects.
4818 It was meant to be temporary and it often doesn't work,
4819 because when IDX has side effects the behavior of IDX==IDX
4820 is undefined. See Stefan Monnier in
4821 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4823 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4825 * lisp.h (functionp): New function (extracted from Ffunctionp).
4826 (FUNCTIONP): Use it.
4827 * eval.c (Ffunctionp): Use it.
4829 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4831 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4832 as that's faster and simpler than static storage. Don't bother
4833 with the g_main_context_query overhead if g_main_context_pending
4834 says no events are pending.
4835 (gfds, gfds_size): Remove these static vars.
4836 (xgselect_initialize): Remove; no longer needed.
4837 All uses and decls removed.
4839 * emacs.c (fatal_error_signal_hook): Remove.
4840 All uses removed. This leftover from old code was always 0.
4842 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4843 * casefiddle.c (casify_object, casify_region):
4844 * casetab.c (set_case_table):
4845 * category.c, category.h (word_boundary_p):
4846 * category.h (CHAR_HAS_CATEGORY):
4847 Use bool for booleans, instead of int.
4849 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4851 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4853 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4855 On assertion failure, print backtrace if available.
4856 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4857 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4858 * Makefile.in (LIB_EXECINFO): New macro.
4861 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4862 * bytecode.c (exec_byte_code):
4863 * callint.c (check_mark, Fcall_interactively):
4864 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4865 (getenv_internal, sync_process_alive, call_process_exited):
4866 * lisp.h (USE_SAFE_ALLOCA):
4867 Use bool for booleans, instead of int.
4868 * lisp.h, process.h: Adjust prototypes to match above changes.
4869 * callint.c (Fcall_interactively): Don't assume the mark's
4870 offset fits in 'int'.
4872 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4874 * buffer.c, buffer.h: Use bool for boolean.
4875 * buffer.c (reset_buffer_local_variables)

4881 (mmap_enlarge, mmap_set_vars):
4882 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4883 Use bool for booleans, instead of int.
4884 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4885 since the 1-or-0 return value is always ignored anyway.
4886 (mmap_initialized_p):
4887 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4888 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4890 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4892 * bidi.c: Use bool for boolean.
4893 This is a bit more readable, and makes the text segment of bidi.o
4894 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4895 Presumably it's faster too.
4896 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

4901 (bidi_explicit_dir_char, bidi_level_of_next_char)
4902 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4903 Use bool for booleans, instead of int.
4904 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4905 (bidi_unshelve_cache): Adjust decls to match code.
4907 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4909 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4912 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4914 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4915 * atimer.h: Include <stdbool.h>.
4917 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4919 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4920 compile time tests instead of run time tests on systems that do
4922 (FRAME_MAC_P): Remove leftover from deleted code.
4923 * frame.c (syms_of_frame): Remove leftover from deleted code.
4925 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4927 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4929 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4931 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4932 Otherwise, the compiler complains about (A?B:C) where B is void
4933 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4934 (fontset_add): Return void, for FONTSET_ADD.
4936 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4938 * alloc.c: Use bool for booleans.
4939 (gc_in_progress, abort_on_gc)
4940 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4941 (dont_register_blocks) [GC_MALLOC_CHECK]:
4942 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

4944 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4945 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4946 (mark_stack, valid_pointer_p, make_pure_string)
4947 (Fgarbage_collect, survives_gc_p, gc_sweep):
4948 Use bool for booleans, instead of int.
4949 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4950 Remove unused local.
4951 * alloc.c (PURE_POINTER_P):
4952 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4953 * editfns.c (Fformat):
4954 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4956 * fns.c (sweep_weak_table):
4957 * lisp.h (suppress_checking, push_message, survives_gc_p)
4958 (make_pure_string, gc_in_progress, abort_on_gc):
4959 * lread.c (readchar, read1):
4960 * print.c (Fprin1_to_string):
4961 * xdisp.c (push_message):
4962 Use bool for booleans affected directly or indirectly by
4965 Make recently-introduced setters macros.
4966 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4967 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4968 (set_fontset_default, set_fontset_fallback): Rename from their
4969 upper-case counterparts, and make them functions rather than macros.
4970 This is more consistent with the other recently-introduced setters.
4971 These don't need to be inline, since they're local.
4973 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4975 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4976 the loop (Bug#12247).
4978 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4980 * lisp.h (vcopy): Use memcpy rather than our own loop.
4981 This fixes a performance regression introduced by the recent
4982 addition of vcopy. This means 'vcopy' will need to be modified
4983 for a copying collector, but that's OK. Also, tighten the
4984 checking in the assertion.
4986 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4988 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4989 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4990 non-base glyph for the width of the base character, according to
4991 what x_draw_composite_glyph_string_foreground expects.
4992 Generate WADJUST value according to composition_gstring_width's
4993 expectations, to produce correct width of the composed character.
4994 Reverse the sign of the DU offset produced by ScriptPlace.
4996 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4998 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5000 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

5080 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>

5083 as gnulib does this if the system doesn't.
5084 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

5955 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5956 * w32.c (init_environment): Change the default values of many
5957 environment variables in dflt_envvars[] to NULL, to avoid pushing
5958 them into environment when they were not already defined.
5959 Remove the code that deletes site-lisp subdirectories from the default
5960 value of EMACSLOADPATH, as it is no longer needed.
5961 (check_windows_init_file): Now external, not static.
5962 Use Vload_path as is, without adding anything, as this function is now
5963 called when Vload_path is already set up.
5965 * w32.h (check_windows_init_file): Add prototype.
5967 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
5968 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
5969 compatibility with Posix platforms.
5970 (main): Move the call to check_windows_init_file to here from

5974 installation tree, as appropriate.
5976 * callproc.c (init_callproc_1): Call decode_env_path instead of
5977 doing its equivalent by hand.
5978 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5979 the code that sets Vexec_path run on MS-Windows.
5981 * lread.c (init_lread): Add comments to #ifdef's.
5983 * msdos.c (dos_set_window_size, IT_update_begin)

5991 Now constants, not macros.
5993 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
5995 Remove unnecessary casts involving pointers.
5996 These casts are no longer needed now that we assume C89 or later,
5997 since they involve casting to or from void *.

6010 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6011 Remove unnecessary pointer casts.
6012 * alloc.c (record_xmalloc): New function.
6013 * lisp.h (record_xmalloc): New decl.
6014 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6015 more like a function. This is because the pointer cast is not
6016 needed. All uses changed.
6017 * print.c (print_string, print_error_message): Avoid length recalc.
6019 Improve fix for macroexp crash with debugging (Bug#12118).
6020 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6021 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6022 not supposed to be invoked from the garbage collector.
6023 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6024 (gc_aset): New function, which is like ASET but can be
6025 used in the garbage collector.
6026 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6041 headers (most versions of MinGW w32api don't).
6042 (get_security_info, create_symbolic_link)
6043 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6045 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6046 in the argument file name.

6054 with addition of handling of symlinks and support for 'lstat'.
6055 If possible, get file's attributes and security information by
6056 handle, not by name. Produce S_IFLNK bit for symlinks, when
6057 called from 'lstat'.
6058 (stat, lstat): New functions, call 'stat_worker'.
6059 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6060 symlinks when the underlying filesystem supports them.
6062 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6064 Fix macroexp crash on Windows with debugging (Bug#12118).
6065 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6066 checking subscripts; problem introduced with the recent
6067 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6068 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6069 since it's used in non-static inline functions now.
6071 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6072 Don't assume buffer size fits in 'int'. Remove unused local.

6092 * composite.c (COMPOSITE_INLINE):
6093 * dispnew.c (DISPEXTERN_INLINE):
6094 * sysdep.c (SYSTIME_INLINE):
6095 Define to EXTERN_INLINE, so that the corresponding functions
6096 are compiled into code.
6097 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6098 (INLINE_HEADER_END): New macros.
6099 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6121 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6123 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6124 This how ASET and AREF are supposed to work, and makes
6125 it easier to think about future improvements. See
6126 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6127 * charset.h (set_charset_attr): New function.

6380 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
6381 does that unconditionally. Remove file, which is now empty.
6383 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
6386 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
6388 Export to GDB most of lisp.h's remaining object-like macros.

6504 * w32inevt.c: Include w32inevt.h.
6505 (w32_read_console_input): New inline function, calls either
6506 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6507 w32_console_unicode_input.
6508 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6509 (w32_kbd_patch_key, key_event): Use the codepage returned by
6510 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

6539 * alloc.c (listn): Fix the order the arguments are consed onto the
6542 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6543 enumeration constants, as PURE and HEAP are too general, and clash
6544 with other headers and sources, such as gmalloc.c and the
6545 MS-Windows system headers. All users changed.
6547 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6549 Revert last save_excursion_save and save_excursion_restore changes.
6550 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6560 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
6562 Improve GDB symbol export (Bug#12036).
6563 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6564 arms of an 'if', not using conditional expressions; otherwise GDB
6565 complains about the types in the unevaluated arm when the argument
6566 is an integer literal.
6567 (xgetint): Simplify expression.
6568 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6569 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6570 Zaretskii in <http://bugs.gnu.org/12036#13>.
6571 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6572 needed now that we have gdb_make_enums_visible.
6573 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6574 (enum enum_USE_LSB_TAG):
6575 New enum types, packaging up enums that need to be exported to GDB.

6594 * xfns.c (syms_of_xfns): Likewise.
6596 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6598 Fast save_excursion_save and save_excursion_restore.
6599 * lisp.h (struct Lisp_Excursion): New data type.
6600 (PVEC_EXCURSION): New pseudovector type.
6601 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6602 to deal with it. Adjust comments.
6603 (init_marker, attach_marker): New prototype.
6604 (unchain_marker): Adjust prototype.

6613 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6615 Fix export of symbols to GDB (Bug#12036).
6616 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6617 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6618 emacs.c, as this is a more-suitable home. Had this been done earlier
6619 the fix for 12036 would have avoided some of the problems noted in
6620 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6621 would have been more obvious.
6622 * emacs.c: Do not include <verify.h>; no longer needed.
6623 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6624 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6625 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

6629 (DATA_SEG_BITS): Use it.
6630 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6631 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6632 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6633 not be usable in #if. This simplifies things.
6635 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6637 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6639 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

6642 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6643 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6644 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6645 Adjust to changes in lisp.h and emacs.c, by using
6646 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6647 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6648 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6649 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6650 instead of gdb_valbits.
6651 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6652 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6653 instead of gdb_array_mark_flag.
6654 (xboolvector): Get size from $->size, not $->header.size.
6655 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6656 (xreload, hook-run, hookpost-run): Remove.
6657 * emacs.c: Include <verify.h>.
6658 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6659 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6661 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6662 (gdb_USE_LSB_TAG): New enum constants.
6663 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6664 Also define these as enum constants, so they're visible to GDB.
6665 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6666 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6667 as constants, so they're visible to GDB.
6668 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6669 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6670 Now enum constants, not macros, so they're visible to GDB.
6671 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6672 more convenient now. All uses changed.
6673 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6674 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6676 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
6678 Explicitly free restriction data that are not needed anymore.
6679 * editfns.c (save_restriction_restore): Free restriction data.
6681 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6683 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6684 add argument, tune behavior, and adjust all callers.
6686 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6688 Use typedef for EMACS_INT, EMACS_UINT.
6689 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6690 than macros. This simplifies debugging in the usual case, since
6691 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6692 and it allows expressions involving EMACS_INT casts.
6693 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6695 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6703 that FOCUS-FRAME can be omitted.
6705 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6707 Adjust buffer text indirection counters at the end of Fkill_buffer.
6708 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6709 buffer is definitely dead. This should really fix an issue reported
6710 by Christoph Scholtes again. (Bug#12007).
6711 (init_buffer_once): Initialize indirection counters of
6712 buffer_defaults and buffer_local_symbols (for sanity and safety).
6714 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6716 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6717 and continuation glyphs on tooltip frames, leave them at zero.
6718 Avoids continued lines in tooltips. (Bug#11832)
6720 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6722 Simplify copy_overlay.
6723 * buffer.c (copy_overlay): Simplify. Use build_marker.

6729 or invalid. (Bug#12025)
6731 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
6732 it signals an error when a tooltip frame is being created.
6734 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6736 Cleanup miscellaneous objects allocation and initialization.
6737 * alloc.c (allocate_misc): Change to static. Add argument to
6738 specify the subtype. Adjust comment and users.
6739 (build_overlay): New function.
6740 * buffer.c (copy_overlays, Fmake_overlay): Use it.
6741 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
6742 (allocate_misc): Remove prototype.
6743 (build_overlay): Add prototype.
6745 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6747 Swap buffer text indirection counters in Fbuffer_swap_text.
6748 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6749 This avoids crash reported by Christoph Scholtes at
6750 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6752 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6754 * nsmenu.m (Popdown_data): New struct.

7513 The functional style also makes code easier to read and maintain.
7514 * systime.h: Include <sys/time.h> on all hosts, not just if
7515 WINDOWSNT, since 'struct timeval' is needed in general.

7555 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7556 Prefer snprintf to strncpy.
7557 * nsterm.m (ns_term_init):
7558 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7559 * nsterm.m (ns_term_init):
7560 Avoid the need for strncpy, by using build_string or
7561 make_unibyte_string directly. Use dtoastr, not snprintf.
7562 * process.c (Fmake_network_process): Diagnose service names that
7563 are too long, rather than silently truncating them or creating
7564 non-null-terminated names.
7565 (Fnetwork_interface_info): Likewise, for interface names.

7581 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7582 where argument type is known to be a Lisp_Cons.

7634 We include usg5-4-common.h, which defines them both.
7636 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7637 O_RDONLY already includes it).
7639 Stop ns builds setting the EMACSLOADPATH environment variable.
7640 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7641 Now it does not set EMACSLOADPATH, just returns the load-path string.
7642 * nsterm.h: Update accordingly.
7643 * lread.c [HAVE_NS]: Include nsterm.h.
7644 (init_lread) [HAVE_NS]: Use ns_load_path.

7654 (ns_init_paths): Do not set EMACSPATH.
7655 * nsterm.h (ns_exec_path): Add it.
7656 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7659 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7661 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7663 * process.c (wait_reading_process_output): 'waitchannels' was unset
7664 when read_kbd || !NILP (wait_for_cell); fix this.
7666 Add GCC-style 'const' attribute to functions that can use it.
7667 * character.h (char_resolve_modifier_mask):
7668 * keyboard.h (make_ctrl_char):
7669 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7670 (init_character_once, next_almost_prime, init_fns, init_image)
7671 (flush_pending_output, init_sound):

7678 Add decls with ATTRIBUTE_CONST.
7680 Minor improvements to make_formatted_string.
7681 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7682 where int is good enough, as vsprintf returns an int.
7683 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7685 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7687 Use make_formatted_string to avoid double length calculation.
7688 * lisp.h (make_formatted_string): New prototype.
7689 * alloc.c (make_formatted_string): New function.
7690 * buffer.c (Fgenerate_new_buffer_name): Use it.

7693 * filelock.c (get_boot_time): Likewise.
7694 * frame.c (make_terminal_frame, set_term_frame_name)
7695 (x_report_frame_params): Likewise.
7696 * image.c (gs_load): Likewise.

7708 * nsterm.h (ns_etc_directory): Add it.
7709 * callproc.c [HAVE_NS]: Include nsterm.h.
7710 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
7712 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7714 Move marker debugging code under MARKER_DEBUG.
7715 * marker.c (MARKER_DEBUG): Move marker debugging code under
7716 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7717 for bootstrap with --enable-checking (~3x slowdown reported
7718 by Juanma Barranquero <lekktu@gmail.com>).
7719 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7721 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7723 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7724 See <http://bugs.gnu.org/11825#29>.
7726 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7728 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7729 has no font, use the frame's font. (Bug#11813)
7730 (display_line): Add commentary about displaying truncation glyphs
7732 (produce_special_glyphs): Move here from term.c.
7734 * term.c (produce_special_glyphs): Move to xdisp.c.
7736 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7739 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7741 * xdisp.c (display_line): Avoid warning about implicit declaration
7744 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7746 * lisp.h: Remove empty conditional.
7748 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7750 * lread.c (load_path_check): Now static.
7752 Fix some minor --with-ns problems found by static checking.
7753 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7754 (x_set_font) [!HAVE_X_WINDOWS]:
7755 * image.c (xpm_load_image) [HAVE_NS]:
7756 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7757 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7758 Remove unused local.
7759 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7760 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7761 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7762 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7763 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7764 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7765 Fix pointer signedness problem.
7766 * xfaces.c (FRAME_X_FONT_TABLE):
7767 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7769 2012-07-07 Glenn Morris <rgm@gnu.org>
7771 * lread.c (load_path_check): New function, split from init_lread.
7772 (init_lread): Reorganize. Motivation:
7773 If EMACSLOADPATH is set, check/warn about that rather than the
7774 defaults, which we are not going to use. Hence we can remove
7775 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7776 Don't warn if site-lisp directories are missing.
7777 If not installed, start from a blank load-path, since
7778 PATH_LOADSEARCH refers to the eventual installation directories.
7780 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7782 Support truncation and continuation glyphs on GUI frames, when
7783 fringes are disabled. (Bug#11832)
7784 * xdisp.c (init_iterator): Get dimensions of truncation and
7785 continuation glyphs even if on GUI frames.
7786 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7787 or both, are absent.
7788 (start_display, move_it_in_display_line_to): Handle the case of a
7789 GUI frame without a fringe to display continuation or truncation
7791 (insert_left_trunc_glyphs): Support GUI frames: make sure
7792 truncation glyphs overwrite enough glyphs from the current line to
7793 have sufficient space in pixels.
7794 (display_line): Support truncation and continuation glyphs on GUI
7795 frames. If some spare pixels are left on the line after inserting
7796 the truncation glyphs, fill that space with a stretch glyph of a
7797 suitably computed width.
7799 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7800 produce_glyphs, to support GUI sessions.
7802 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7804 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7806 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7808 Do not require float-time's arg to fit in time_t (Bug#11825).
7809 This works better on hosts where time_t is unsigned, and where
7810 float-time is applied to the (negative) difference between two times.
7811 * editfns.c (decode_time_components): Last arg is now double *,
7812 not int *, and means to store all the result as a double, without
7813 worrying about whether the seconds part fits in time_t.
7814 All callers changed.
7815 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7816 All callers changed.
7817 (Ffloat_time): Do not fail merely because the specified time falls
7818 outside of time_t range.
7820 2012-07-07 Glenn Morris <rgm@gnu.org>
7822 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7829 Update dependencies.
7831 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7833 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

7837 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7838 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7839 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

7842 * xfont.c (compare_font_names): Redo to omit the need for casts.
7844 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7846 * xfns.c (Fx_change_window_property): Doc fix.
7847 * w32fns.c (Fx_change_window_property): Doc fix.
7849 * w32fns.c (Fx_window_property): Accept the same arguments as the
7850 X Windows version. Doc fix.
7851 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7853 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7854 Eli Zaretskii <eliz@gnu.org>
7856 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7857 Windows-specific code from nt/config.nt moved here.
7858 Obsolete settings removed.
7860 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7862 * process.c: Avoid unnecessary calls to gettime.
7863 (wait_reading_process_output): Don't get the time of day
7864 when gobbling data immediately and not waiting, as there's no need
7865 for it in that case. This removes a FIXME.
7867 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7869 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7870 is defined (Bug#11768).
7872 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7874 Fix marker debugging code.
7875 * marker.c (byte_char_debug_check): Do not perform the check
7876 if buffer is not multibyte.
7877 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7878 Call byte_char_debug_check with correct arguments.
7880 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7882 Compile marker debugging code only if ENABLE_CHECKING is defined.
7883 * marker.c (byte_char_debug_check, count_markers):
7884 Use only if ENABLE_CHECKING is defined.
7885 (byte_debug_flag): Remove.
7886 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7887 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7889 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7891 Avoid code repetition in marker-related functions.
7892 * marker.c (attach_marker): New function.
7893 (Fset_marker, set_marker_restricted, set_marker_both)
7894 (set_marker_restricted_both): Use it.
7895 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7896 Consistently rename charno to charpos.
7897 (marker_position): Add eassert.
7898 (marker_byte_position): Convert to eassert.

7914 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7915 (save_restriction_save): Use build_marker.
7916 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7917 * window.c (save_window_save): Likewise.
7919 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7921 Do not use Fdelete_overlay in delete_all_overlays
7922 to avoid redundant calls to unchain_overlay.
7923 * buffer.c (drop_overlay): New function.
7924 (delete_all_overlays, Fdelete_overlay): Use it.
7925 * minibuf.c (get_minibuffer): Fix comment.
7927 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7929 Port to OpenBSD 5.1 amd64.
7930 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7931 This is needed for OpenBSD, and should be harmless on all BSD systems.
7932 Also, include <sys/sysctl.h>, as it should be available on all
7933 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7934 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7935 use p_pid member, not kp_proc.pid.
7937 2012-07-06 Glenn Morris <rgm@gnu.org>
7939 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7941 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7943 More xmalloc and related cleanup.
7944 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7945 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

7951 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7952 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7954 Omit needless casts involving void * pointers and allocation.
7955 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7956 as the former is more robust if P's type is changed.
7957 Prefer xzalloc to xmalloc + memset 0.
7958 Simplify malloc-or-realloc to realloc.
7959 Don't worry about xmalloc returning a null pointer.
7960 Prefer xstrdup to xmalloc + strcpy.
7961 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7963 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7964 alloca of a constant.
7966 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7968 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7969 hscroll is larger than the line width. Fixes long and futile
7970 looping inside extend_face_to_end_of_line (on a TTY) producing
7971 glyphs that are not needed and thrown away.
7973 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7975 * marker.c (set_marker_restricted_both): Simplify by using

7989 followed by gtk_box_set_homogeneous (Bug#11768).
7990 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7991 (update_theme_scrollbar_width, xg_create_scroll_bar):
7992 Use gtk_scrollbar_new (Bug#11768).
7993 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7994 (is_box_type): New function (Bug#11768).
7995 (xg_tool_item_stale_p): Call is_box_type.
7996 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
7997 with default display (Bug#11768).

8001 * xdisp.c (window_hscroll_limited): New function.
8002 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8003 coordinates when window's hscroll is set to insanely large
8006 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8008 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8075 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8076 This should be fixed in a better way; see Eli Zaretskii in
8077 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8078 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8080 * fileio.c (time_error_value): Rename from special_mtime.
8081 The old name's problems were noted by Eli Zaretskii in
8082 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8084 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8085 This variable's comment says Emacs needs at least one GDB-visible
8086 symbol of type enum pvec_type, to work around GDB problems.
8087 The symbol's value doesn't matter.
8089 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8090 that causes compilation to fail on pre-C99 compilers.
8092 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8094 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

8116 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8117 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8118 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8119 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8120 abusing vector->header.next.nbytes.
8121 (live_vector_p): Use PVEC_TYPE.
8122 (mark_object): Adapt code to extract pvectype. Use switch.
8124 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8126 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8127 Tighten new eassert a bit.
8129 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8131 Fix compilation with --enable-gcc-warnings and -O1
8133 * doprnt.c (doprnt): Change type of tem to int, initialize
8134 to avoid compiler warning. Add eassert.
8135 * search.c (simple_search): Initialize match_byte to avoid
8136 compiler warning. Add eassert.
8138 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8140 Avoid weird behavior with large horizontal scrolls.
8141 Without this change, for example, large hscroll values would
8142 mess up Emacs's display on Fedora 15 x86, presumably due to
8143 overflows in int calculations in the display code.
8144 Also, if buffers had long lines, Emacs would freeze.
8145 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8146 (set_window_hscroll): New function, containing the old guts of
8147 Fset_window_hscroll. Return the clipped value.
8148 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8149 This avoids the need to check against PTRDIFF_MAX.
8151 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8153 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8155 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8157 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8159 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8160 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8161 since GCC 4.4.6 issues a bogus warning for them.
8163 Fix bugs in file timestamp newness comparisons.
8164 * fileio.c (Ffile_newer_than_file_p):
8165 * lread.c (Fload): Use full timestamp resolution of files,
8166 not just the 1-second resolution, so that files that are only
8167 slightly newer still count as newer.
8168 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8169 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8171 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8173 * fileio.c: Improve handling of file time marker. (Bug#11852)
8174 (special_mtime): New function.
8175 (Finsert_file_contents, Fverify_visited_file_modtime):
8176 Use it to set special mtime values consistently.
8178 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8180 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8181 marker for non-existing file. (Bug#11852)
8183 2012-07-03 Glenn Morris <rgm@gnu.org>
8185 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8186 and did not make it into globals.h).
8188 2012-07-03 Tom Tromey <tromey@redhat.com>
8190 * window.c (Fset_window_margins, Fset_window_fringes)
8191 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8192 * textprop.c (Fprevious_property_change): No longer static.
8193 * syntax.c (Fsyntax_table_p): No longer static.
8194 * process.c (Fget_process, Fprocess_datagram_address): No longer

8208 * dired.c (Ffile_attributes): No longer static.
8209 * composite.c (Fcomposition_get_gstring): No longer static.
8210 * callproc.c (Fgetenv_internal): No longer static.
8212 * ccl.h: Remove EXFUNs.
8213 * buffer.h: Remove EXFUNs.
8214 * dispextern.h: Remove EXFUNs.
8215 * intervals.h: Remove EXFUNs.
8216 * fontset.h: Remove EXFUN.
8217 * font.h: Remove EXFUNs.
8218 * dosfns.c (system_process_attributes): Remove EXFUN.
8219 * keymap.h: Remove EXFUNs.
8220 * lisp.h: Remove EXFUNs.
8221 * w32term.h: Remove EXFUNs.
8222 * window.h: Remove EXFUNs.
8223 * xsettings.h: Remove EXFUN.
8224 * xterm.h: Remove EXFUN.
8226 2012-07-03 Glenn Morris <rgm@gnu.org>
8228 * lisp.h (Frandom): Make it visible to C.
8229 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8230 buffer for invisible buffers. (Bug#1229)
8232 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8234 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8235 values which aren't power of 2.
8236 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8237 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8240 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8242 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8244 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8246 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8248 * alloc.c (allocate_vector_block): Remove redundant
8249 calls to mallopt if DOUG_LEA_MALLOC is defined.
8250 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8251 avoid calls to mallopt if zero_vector is returned.
8253 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8255 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8256 is enabled, avoid dereferencing NULL current_sblock if
8259 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8261 Cleanup basic buffer management.
8262 * buffer.h (struct buffer): Change layout to use generic vector
8263 marking code. Fix some comments. Change type of 'clip_changed'
8264 to bitfield. Remove unused #ifndef old.
8265 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8266 (GET_OVERLAYS_AT): Fix indentation.
8267 (for_each_per_buffer_object_at): New macro.
8268 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8269 (Fbuffer_local_variables): Use it.
8270 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8271 * alloc.c (allocate_buffer): Adjust to match new layout of
8272 struct buffer. Fix comment.
8273 (mark_overlay): New function.
8274 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8275 Lisp area of struct buffer.
8276 (mark_object): Use it. Adjust marking of misc objects
8277 and related comments.
8279 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8281 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8282 wrapper that is not needed because the wrapped code is a no-op (zero
8283 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8284 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8286 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8288 * alloc.c (mark_buffer): Simplify. Remove prototype.
8289 (mark_object): Add comment. Reorganize marking of vector-like
8290 objects. Use CHECK_LIVE for all vector-like objects except buffers
8291 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8292 Avoid redundant calls to mark_vectorlike for bool vectors.
8294 2012-06-30 Glenn Morris <rgm@gnu.org>
8296 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8298 * epaths.in (PATH_SITELOADSEARCH): New.
8299 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8300 This is rather than relying on --enable-locallisppath elements
8301 having "site-lisp" in their names. (Bug#10208#25, 11658)
8303 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8305 * w32proc.c (sys_select): Accept and ignore one more argument.
8307 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8309 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8310 (pselect) [!MS_DOS]: Redirect to sys_select.
8312 * sysdep.c: Don't include dos.h and dosfns.h.
8314 * process.c (sys_select):
8315 * msdos.c (sys_select): Accept one more argument and ignore it.
8317 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8318 adapt data types and code to that.
8321 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8322 which clashes with the gnulib function of the same name.
8324 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8326 * font.c (font_style_to_value, font_style_symbolic)
8327 (font_prop_validate_style): Add type checks for values in
8330 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8332 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8335 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8337 * xdisp.c (try_window_id): Undo last change.
8339 * w32.c (getwd): Adjust commentary about startup_dir.
8340 (init_environment): Always call sys_access, even in non-MSVC
8341 builds. Don't chdir to the directory of the Emacs executable.
8342 This undoes code from 1997 which was justified by the need to
8343 "avoid conflicts when removing and renaming directories". But its
8344 downside was that every relative file name was being interpreted
8345 relative to the directory of the Emacs executable, which can never
8346 be TRT. In particular, it broke sys_access when called with
8347 relative file names.
8348 (sys_access): Map GetLastError to errno.
8350 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8352 * window.h (struct window): Change type of 'fringes_outside_margins'

8356 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8359 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8361 * gnutls.c (emacs_gnutls_handshake):
8362 Add QUIT to make the loop interruptible.
8364 2012-06-29 Glenn Morris <rgm@gnu.org>
8366 * charset.c (init_charset): Make lack of etc/charsets fatal.
8368 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8370 * editfns.c (region_limit): Fix type mismatch.
8372 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8374 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8375 undefined. Convert from xassert to eassert.
8376 * nsmenu.m: Convert from xassert to eassert.
8377 * nsterm.m: Likewise.
8379 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8381 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8383 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8385 Avoid integer overflow on scroll-left and scroll-right.
8386 * window.c (HSCROLL_MAX): New macro.
8387 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8388 overflow when requested scroll falls outside ptrdiff_t range.
8390 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8392 * window.h (struct window): Change type of 'hscroll',
8393 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8394 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8395 Adjust users accordingly.
8396 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8397 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8398 from EMACS_INT to ptrdiff_t.
8399 (make_window): Omit redundant initialization.
8401 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8405 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8407 * window.h (struct window): Change type of 'use_time' and

8469 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
8470 avoid GCC warning about unused macro.
8472 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8474 * alloc.c (allocate_string): Omit intervals initialization.
8475 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8476 as in make_pure_string and make_pure_c_string.
8478 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8480 * alloc.c (allocate_string): Fix last change.
8482 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8532 * alloc.c: Remove build_string.
8533 * lisp.h: Define build_string as static inline. This provides
8534 a better opportunity to optimize away calls to strlen when the
8535 function is called with compile-time constant argument.
8536 * image.c (imagemagick_error): Convert to build_string.
8537 * w32proc.c (sys_spawnve): Likewise.
8538 * xterm.c (x_term_init): Likewise.
8540 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8542 Use sprintf return value instead of invoking strlen on result.
8543 In the old days this wasn't portable, since some sprintf
8544 implementations returned char *. But they died out years ago and
8545 Emacs already assumes sprintf returns int.
8546 Similarly for float_to_string.
8547 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8548 * ccl.c (ccl_driver):
8549 * character.c (string_escape_byte8):

8552 * print.c (print_object):
8553 * xdisp.c (message_dolog):
8554 * xfns.c (syms_of_xfns):
8555 Use sprintf or float_to_string result to avoid need to call strlen.
8556 * data.c (Fnumber_to_string):
8557 Use make_unibyte_string, since the string must be ASCII.
8558 * lisp.h, print.c (float_to_string): Now returns int length.
8559 * term.c (produce_glyphless_glyph):
8560 Use sprintf result rather than recomputing it.
8562 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8563 * Makefile.in (ALL_CFLAGS):
8564 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8586 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
8588 * gtkutil.c (get_utf8_string): Remove redundant assignment.

8593 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8595 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8598 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8600 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8601 instead of truncating it to 63 (admittedly a generous limit).
8603 * process.c: Fix spelling and caps in comments.
8605 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8607 * emacs.c (setpgrp): Remove definition, unused.

8617 (SYSTIME_H): Add nt/inc/sys/time.h.
8619 * systime.h [WINDOWSNT]: Include sys/time.h.

8731 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8733 Support higher-resolution time stamps (Bug#9000).
8734 The time stamps are only nanosecond-resolution at the C level,
8735 since that's the best that any real-world system supports now.
8736 But they are picosecond-resolution at the Lisp level, as that's
8737 easy, and leaves room for future OS improvements.
8739 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8742 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8743 Don't get current time unless it's needed.
8745 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8746 now provides it if it's absent.
8747 (start_atimer): Port to higher-res time stamps.
8748 Check for time stamp overflow. Don't get current time more
8749 often than is needed.
8751 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8752 Include systime.h, not time.h.
8753 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8755 * dired.c: Include stat-time.h.
8756 (Ffile-attributes): File times now have higher resolution.
8758 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8759 (struct image): Timestamp now has higher resolution.
8761 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8762 has at least microseconds now. All uses removed.
8763 (update_frame, update_single_window, update_window, update_frame_1)
8764 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8765 (duration_to_sec_usec): Remove; no longer needed.
8767 * editfns.c (time_overflow): Now extern.

8773 (decode_time_components, lisp_seconds_argument): New functions.
8774 (make_time): Now static.
8775 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8776 Report an error if the time is invalid, rather than having the caller
8779 * fileio.c: Include <stat-time.h>
8780 (Fcopy_file): Copy higher-resolution time stamps.
8781 Prefer to set the time stamp via a file descriptor if that works.

8783 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8784 (Fvisited_file_modtime, Fset_visited_file_modtime):
8785 Support higher-resolution time stamps.
8787 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8789 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8791 * image.c (prepare_image_for_display, clear_image_cache)
8792 (lookup_image): Port to higer-resolution time stamps.
8794 * keyboard.c (start_polling, bind_polling_period):
8795 Check for time stamp overflow.
8796 (read_char, kbd_buffer_get_event, timer_start_idle)
8797 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8798 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8799 Port to higher-resolution time stamps. Do not assume time_t is signed.
8800 (decode_timer): New function. Timers are now vectors of length 9,
8801 not 8, to accommodate the picosecond component.
8802 (timer_check_2): Use it.
8804 * nsterm.m (select_timeout, timeval_subtract): Remove.
8805 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8806 as they're a bit more accurate and handle overflow better.
8807 (ns_select): Change prototype to be compatible with pselect.
8808 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8809 * nsterm.h (ns_select): Adjust prototype.
8811 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8812 us-resolution time stamps.
8813 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8815 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8817 * lisp.h (time_overflow): New decl.
8818 (wait_reading_process_output): First arg is now intmax_t, not int,
8819 to accommodate larger waits.
8821 * process.h (struct Lisp_Process.read_output_delay):
8822 Now counts nanoseconds, not microseconds.
8823 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8825 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8826 (wait_reading_process_output):
8827 Port to ns-resolution time stamps.
8828 (Faccept_process_output, wait_reading_process_output):
8829 Check for time stamp overflow. Do not assume time_t is signed.
8830 (select_wrapper): Remove; we now use pselect.
8831 (Fprocess_attributes): Now generates ns-resolution time stamps.
8833 * sysdep.c: Include utimens.h. Don't include utime.h
8834 or worry about struct utimbuf; gnulib does that for us now.
8835 (gettimeofday): Remove; gnulib provides a substitute.
8836 (make_timeval): New function.
8837 (set_file_times): Now sets ns-resolution time stamps.
8838 New arg FD; all uses changed.
8839 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8840 (system_process_attributes):
8841 Now returns ns-resolution time stamp. All uses changed.
8842 Check for time stamp overflow.
8844 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8845 provides a substitute now.
8847 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8848 since it guarantees struct timespec.
8849 (EMACS_TIME): Now struct timespec, so that we can support
8850 ns-resolution time stamps.
8851 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8852 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8853 (EMACS_USECS): Remove.
8854 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8855 so multiply the arg by 1000 before storing it.
8856 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8858 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8859 Port to ns-resolution time stamps.
8860 (EMACS_TIME_NEG_P): Remove; replaced by....
8861 (EMACS_TIME_SIGN): New macro.
8862 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8863 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8864 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8865 (make_timeval, make_lisp_time, decode_time_components): New decls.
8866 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8867 that it mishandled time_t overflow. You can't compare by subtracting!
8868 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8869 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8871 * term.c: Include <sys/time.h>.
8872 (timeval_to_Time): New function, for proper overflow wraparound.

8877 (Fprimitive_undo): Use them when restoring time stamps.
8879 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8880 (w32_get_internal_run_time):
8881 Port to higher-resolution Emacs time stamps.
8882 (ltime): Now accepts single 64-bit integer, as that's more convenient
8885 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8887 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8888 for compatibility with pselect. Support ns-resolution time stamps.
8890 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8892 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8893 Check for time stamp overflow, and support ns-resolution time stamps.
8895 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8896 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8897 (timeval_subtract): Remove; no longer needed.
8898 (XTflash, XTring_bell, x_wait_for_event):
8899 Port to ns-resolution time stamps. Don't assume time_t is signed.
8901 2012-06-22 Chong Yidong <cyd@gnu.org>

8905 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8907 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8908 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8909 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8910 staticidx goes up to 1597 out of 1600 = 0x640.)
8912 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8914 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8915 Otherwise, the umask might be mistakenly 0 while handling input signals.

8926 access to `contents' member of Lisp_Vector objects with AREF and ASET
8929 2012-06-19 Chong Yidong <cyd@gnu.org>
8931 * frame.c (delete_frame): When selecting a frame on a different

8936 (unwind_format_mode_line): Restore them.
8937 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8939 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8940 since tty frames can be explicitly named.
8941 (prepare_menu_bars): Likewise.
8943 * term.c (Ftty_top_frame): New function.
8945 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8948 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8949 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8950 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8951 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8952 (METER_1, METER_2): Simplify.
8954 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

8958 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8960 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8961 gets killed during executing of this function (Bug#11665).
8962 Try to always return Qt when the buffer has been actually killed.
8963 (Vkill_buffer_query_functions): In doc-string say that functions
8964 run by this hook should not change the current buffer.
8966 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8968 Fix recently-introduced process.c problems found by static checking.

8986 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8988 * lisp.h (eassert): Assume C89 or later.
8989 This removes the need for CHECK.
8990 (CHECK): Remove. Its comments about always evaluating its
8991 argument were confusing, as 'eassert' typically does not evaluate
8994 * coding.c (produce_chars): Use ptrdiff_t, not int.
8996 * xterm.c (x_draw_underwave): Check for integer overflow.
8997 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9181 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
9182 code works fine either way, and efficiency is not a concern here,
9183 as the union type is for debugging, not for production.
9184 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9185 Use an inline function on all platforms when using the union type,
9186 since this is simpler and 'static inline' can be used portably
9188 (LISP_INITIALLY_ZERO): New macro.
9189 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
9190 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

9272 * xdisp.c (vmessage): Treat frame message as multibyte.
9273 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))

9293 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
9295 2012-06-08 Eli Zaretskii <eliz@gnu.org>
9297 * alloc.c (allocate_vectorlike): Fix last change.

9328 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9330 * doprnt.c (doprnt): Truncate multibyte char correctly.
9331 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9332 would mishandle a string argument "Xc" if X was a multibyte
9333 character of length 2: it would truncate after X's first byte
9334 rather than including all of X.
9336 2012-06-06 Chong Yidong <cyd@gnu.org>
9338 * buffer.c (word_wrap): Doc fix.

9387 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9388 Convert pctcpu and pctmem to Lisp float properly.
9389 Let the compiler fold better, as 100.0/0x8000 is exact.
9391 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9393 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9396 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9398 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9400 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>

9403 bitfields where appropriate, remove unused fields.
9404 * window.h (struct window): Remove unused 'last_mark_x' and
9405 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

9407 Change type of 'force_start', 'optional_new_start',
9408 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9409 fields from Lisp_Object to bitfield. Adjust users accordingly.

9415 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:

9417 and 'double' in a couple of places.
9419 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9421 * xdisp.c (handle_stop): Detect whether we have overlay strings
9422 loaded by testing it->current.overlay_string_index to be
9423 non-negative, instead of checking whether n_overlay_strings is
9424 positive. (Bug#11587)
9426 2012-05-31 Chong Yidong <cyd@gnu.org>
9428 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

9434 * search.c (search_buffer): Remove calls to
9435 r_alloc_inhibit_buffer_relocation, as it is now called by
9436 maybe_unify_char, which was the cause of relocation of buffer text
9439 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9441 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9442 for the duration of call to load_charset, to avoid problems with
9443 callers of maybe_unify_char that access buffer text through C
9446 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9447 decrement the inhibition flag, instead of just setting or
9450 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9452 Remove obsolete '#define static' cruft.
9453 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9454 This #undef was "temporary" in 2000; it is no longer needed
9455 now that '#define static' has gone away.
9456 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9457 (gray_bitmap_bits): Remove; no longer needed.
9458 All uses replaced with definiens.

9502 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9503 Bug#9642, but explicitly check that the buffer the overlay would
9504 be moved to is live and rearrange lines to make sure that errors
9505 will not put the overlay in an inconsistent state.
9506 (Fdelete_overlay): Cosmetics.
9508 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9510 * w32term.c (my_bring_window_to_top): New function.

9549 before checking whether it's out of range. Put the check inside
9551 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

9565 they are now on lisp.h.
9567 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9569 * search.c (search_buffer): Use it to inhibit relocation of buffer
9570 text while re_search_2 is doing its job, because re_search_2 is
9571 passed C pointers to buffer text. (Bug#11519)
9573 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9576 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9577 state after an additional call to move_it_in_display_line_to, keep
9578 the values of it->max_ascent and it->max_descent found for the
9580 (pos_visible_p): Revert the comparison against bottom_y to what it
9581 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9584 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9586 Fix coding-related core dumps with gcc -ftrapv.
9587 The code was computing A - B, where A and B are pointers, and B is
9588 random garbage. This can lead to core dumps on platforms that
9589 have special pointer registers, and it also leads to core dumps on
9590 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9591 A - B only when B is initialized properly.
9592 * coding.c (coding_set_source, coding_set_destination): Return void.
9593 (coding_change_source, coding_change_destinations): New functions,
9594 with the old behaviors of coding_set_source and coding_set_destination.

9610 (initialize_w32_display): Initialize mouse-highlight data.
9612 * w32inevt.c: Include termchar.h and window.h.
9613 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9614 moves, call note_mouse_highlight. If help_echo changed, call
9615 gen_help_event to produce help-echo message in the echo area.
9616 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9619 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9621 * lread.c (read1): Simplify slightly to avoid an overflow warning
9622 with GCC 4.7.0 on x86-64.
9624 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9626 * bidi.c (bidi_mirror_char): Revert last change: an int is
9627 definitely wide enough here.
9629 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

9643 Use int, not EMACS_INT, where int is wide enough.
9644 (inhibit_garbage_collection, Fgarbage_collect):
9645 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9663 (Foverlay_recenter, last_overlay_modification_hooks_used)
9664 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9665 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9666 (validate_region): Omit unnecessary test for b <= e,
9667 since that's guaranteed by the previous test.
9668 (adjust_overlays_for_delete): Avoid pos + length overflow.
9669 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9670 (report_overlay_modification):
9671 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9672 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

9674 after the EMACS_INT -> ptrdiff_t change.

9676 * buffer.h: Adjust decls to match defn changes elsewhere.

9681 not int, to avoid needless 32-bit limit on 64-bit hosts.
9682 (exec_byte_code): Use tighter memory-full test, one that checks
9683 for alloca overflow. Don't compute the address of the object just
9684 before an array, as that's not portable. Use EMACS_INT, not
9685 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9686 * callint.c (Fcall_interactively):
9687 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9699 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9700 (casify_object): Avoid integer overflow when overallocating buffer.
9701 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9702 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9703 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9704 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9705 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9706 integers are now checked earlier. All uses replaced with XINT.
9708 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9709 For CCL_MapSingle, check that content and value are in int range.
9710 (ccl_driver, Fregister_code_conversion_map):
9711 Check that Vcode_version_map_vector is a vector.
9712 (resolve_symbol_ccl_program): Check that vector header is in range.
9713 Always copy the vector, so that we can check its contents reliably
9714 now rather than having to recheck each instruction as it's being
9715 executed. Check that vector words fit in 'int'.
9716 (ccl_get_compiled_code, Fregister_ccl_program)
9717 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9718 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9719 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9720 contents are in range.
9721 (Fccl_execute_on_string): Check that status is in range.
9722 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9723 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9724 Accept and return EMACS_INT, not int, because callers can pass values

9731 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9732 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9733 avoid mishandling large integers.

9744 Don't rely on undefined behavior with signed left shift overflow.
9745 Don't assume unsigned int fits into fixnum, or that fixnum fits
9746 into unsigned int. Don't require max_code to be a valid fixnum;
9747 that's not true for gb10830 4-byte on a 32-bit host. Allow
9748 invalid_code to be a cons, for the same reason. Require code_offset
9749 to be a character. Avoid int overflow if max_char is close
9751 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9752 this is intended anyway and avoids some undefined behavior.
9753 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9754 INDEX_TO_CODE_POINT, as that's what it expects.
9755 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9756 * charset.h (DECODE_CHAR): Return int, not unsigned;
9757 this is what was intended anyway, and it avoids undefined behavior.
9758 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9759 integer-overflow issues.
9760 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9761 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9762 where the argument is EMACS_INT, and this behavior is not intended.
9763 * chartab.c (Fmake_char_table, Fset_char_table_range)
9764 (uniprop_get_decoder, uniprop_get_encoder):
9765 Don't assume fixnum fits in int.
9766 * cmds.c (move_point): New function, that does the gist of
9767 Fforward_char and Fbackward_char, but does so while checking
9768 for integer overflow more accurately.
9769 (Fforward_char, Fbackward_char): Use it.
9770 (Fforward_line, Fend_of_line, internal_self_insert)
9771 (internal_self_insert):
9772 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10553 2012-05-14 Glenn Morris <rgm@gnu.org>
10555 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").

10563 (report_error, report_error_1, make_hdr, copy_sym)
10564 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10565 Make arguments const char *, not char *, to avoid violations of C
10566 standard and to fix some AIX warnings reported by Gilles Pion.
10568 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10570 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10571 already have overlays loaded.
10572 (handle_single_display_spec): Before returning without displaying
10573 fringe bitmap, synchronize the bidi iterator with the main display
10574 iterator, by calling iterate_out_of_display_property.
10575 (iterate_out_of_display_property): Detect buffer iteration by
10576 testing that it->string is a Lisp string.
10577 (get_next_display_element): When the current object is exhausted,
10578 and there's something on it->stack, call set_iterator_to_next to
10579 proceed with what's on the stack, instead of returning zero.
10580 (set_iterator_to_next): If called at the end of a Lisp string,
10581 proceed to consider_string_end without incrementing string
10582 position. Don't increment display vector index past the end of
10583 the display vector. (Bug#11417)
10584 (pos_visible_p): Don't report a position visible when move_it_to
10585 stopped at the last line of window, which happens to be scanned
10586 backwards by the bidi iteration. (Bug#11464)
10588 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10590 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10591 and right-margin display specs even if the spec is invalid or we
10592 are on a TTY, and thus unable to display on the fringes.
10593 That's because the text with the property will not be displayed anyway,
10594 so we need to signal to the caller that this is a "replacing"
10595 display spec. This fixes display when the spec is invalid or we
10598 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10600 * unexaix.c (make_hdr): Fix typo in prototype.

10631 Update dependencies.
10633 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10635 * xgselect.c (xg_select): Put maxfds+1 into a var.
10636 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10638 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10640 2012-05-10 Dave Abrahams <dave@boostpro.com>

10647 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10648 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10649 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10650 Initialize xd_registered_buses.
10652 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10654 Untag more efficiently if USE_LSB_TAG.
10655 This is based on a proposal by YAMAMOTO Mitsuharu in
10656 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10657 For an admittedly artificial (nth 8000 longlist) benchmark on
10658 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10659 Emacs's overall text size by 1%.
10660 * lisp.h (XUNTAG): New macro.
10661 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10662 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10663 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10664 * eval.c (Fautoload):
10665 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10666 * frame.h (XFRAME): Use XUNTAG.
10668 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10669 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10670 Remove unportable assumptions about print widths of types like
10672 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10673 intptr_t when converting between pointer and integer, to avoid GCC
10674 warnings about wrong width.
10676 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10678 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10679 stack for each reader_thread, instead of defaulting to 8MB
10680 determined by the linker. This avoids failures in creating
10681 subprocesses on Windows 7, see the discussion in this thread:
10682 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10684 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10686 Fix up display of the *Minibuf-0* buffer in the mini window.
10687 * keyboard.c (read_char): Don't clear the echo area if there's no
10689 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10690 contents of *Minibuf-0*) if there's no message displayed in its stead.
10692 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10694 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10697 2012-05-06 Chong Yidong <cyd@gnu.org>
10699 * lisp.mk (lisp): Update.
10701 2012-05-05 Jim Meyering <meyering@redhat.com>
10703 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10705 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10707 * data.c (PUT_ERROR): New macro.
10708 (syms_of_data): Use it. Add new error type `user-error'.
10709 * undo.c (user_error): New function.
10710 (Fprimitive_undo): Use it.
10711 * print.c (print_error_message): Adjust print style for `user-error'.
10712 * keyboard.c (user_error): New function.
10713 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10715 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10717 Do not limit current-time-string to years 1000..9999.
10718 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10719 (Fcurrent_time_string): Support any year that is supported by the
10720 underlying localtime representation. Don't use asctime, as it
10721 has undefined behavior for years outside the range -999..9999.
10723 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10725 Fix race conditions involving setenv, gmtime, localtime, asctime.
10726 Without this fix, interrupts could mess up code that uses these
10727 nonreentrant functions, since setting TZ invalidates existing
10728 tm_zone or tzname values, and since most of these functions return
10729 pointers to static storage.
10730 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10731 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10732 Grow the critical sections to include not just invoking
10733 localtime/gmtime, but also accessing these functions' results
10734 including their tm_zone values if any, and any related TZ setting.
10735 (format_time_string): Last arg is now struct tm *, not struct tm **,
10736 so that the struct tm is saved in the critical section.
10737 All callers changed. Simplify allocation of initial buffer, partly
10738 motivated by the fact that memory allocation needs to be outside
10739 the critical section.
10741 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10743 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10744 with RESET_INTERVAL.
10746 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10747 Remove duplicated buffer name initialization.
10749 2012-05-02 Jim Meyering <jim@meyering.net>
10751 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10753 * xfns.c (x_window): Use xstrdup (Bug#11375).
10755 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10757 * xdisp.c (pos_visible_p): If already at a newline from the
10758 display string before the 'while' loop, don't walk back the glyphs
10759 from it3.glyph_row. Solves assertion violation when the display
10760 string begins with a newline (egg.el). (Bug#11367)
10762 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10764 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10767 2012-05-01 Glenn Morris <rgm@gnu.org>
10769 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10770 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10771 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10772 All were removed before 23.1.
10774 * dispnew.c: Remove HAVE_LIBNCURSES test;
10775 it is always true on relevant platforms.
10777 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10778 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10780 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10782 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10784 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10785 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10788 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10790 Do not avoid creating empty evaporating overlays (Bug#9642).
10791 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10792 That is, do not delete an evaporating overlay if it becomes
10793 empty after its bounds are adjusted to fit within its buffer.
10794 This fix caused other problems, and I'm reverting it until we get
10795 to the bottom of them.
10797 2012-04-27 Chong Yidong <cyd@gnu.org>
10799 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10801 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10803 * xdisp.c (pos_visible_p): If the window start position is beyond
10804 ZV, start the display from buffer beginning. Prevents assertion
10805 violation in init_iterator when the minibuffer window is scrolled
10806 via the scroll bar.
10808 * window.c (window_scroll_pixel_based): Likewise.
10810 2012-04-27 Chong Yidong <cyd@gnu.org>
10812 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10814 2012-04-27 Glenn Morris <rgm@gnu.org>
10816 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10817 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10819 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10821 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10822 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10824 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10826 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10827 display element, check also the underlying string or buffer
10828 character. (Bug#11341)
10830 * w32menu.c: Include w32heap.h.
10831 (add_menu_item): If the call to AppendMenuW (via
10832 unicode_append_menu) fails, disable Unicode menus only if we are
10833 running on Windows 9X/Me.
10835 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10837 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10838 (xgetint): Add missing shift for LSB tags.
10840 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10842 * keyboard.c (read_char): Don't wipe echo area for select window
10843 events: These might get delayed via `mouse-autoselect-window'
10846 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10848 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10849 manipulation of :loaded-from data.
10851 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10853 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10854 now a cons (bug#11311).
10856 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10858 Do not create empty overlays with the evaporate property (Bug#9642).
10859 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10860 if it becomes empty after its bounds are adjusted to fit within
10861 its buffer. Without this fix, in a nonempty buffer (let ((o
10862 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10863 yields an empty overlay that has the evaporate property, which is
10864 not supposed to happen.
10866 Fix minor GTK3 problems found by static checking.
10867 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

10875 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10876 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10877 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10878 (EMACS_FIXED_GET_CLASS): Remove; unused.

10884 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10886 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10887 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10888 (__malloc_size_t, __malloc_ptrdiff_t):
10889 Remove. All uses removed, replaced by the definiens if needed,
10890 since we can assume C89 or better now.
10891 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
10892 (protect_malloc_state, align, get_contiguous_space)

10898 (special_realloc, _realloc_internal_nolock, _realloc_internal)
10899 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10900 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10901 Define using prototypes, not old style.
10902 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10903 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

10908 Omit no-longer-needed casts.
10909 (valloc): Use getpagesize, not __getpagesize.
10910 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

10966 * alloc.c: Handle unusual debugging option combinations.
10967 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10968 since the two debugging options are incompatible.
10969 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
10971 (mem_init, mem_insert, mem_insert_fixup):
10972 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

10982 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10983 Use Emacs indenting style more consistently. Avoid some casts.
10984 Use 'double' consistently rather than mixing 'float' and 'double'.
10986 2012-04-21 Eduard Wiebe <usenet@pusto.de>
10988 * sysdep.c (list_system_processes, system_process_attributes):

11023 row, return zero immediately.
11024 (try_cursor_movement): If inside continuation line, don't back up
11025 farther than the first row after the header line, if any.

11065 New extern decls, to avoid calling undeclared functions.
11066 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11067 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined

11070 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11071 Remove one incorrect comment and fix another.

11075 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
11076 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
11077 (r_alloc_sbrk): Now static.
11079 Improve ralloc.c interface checking.
11080 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
11081 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

11084 [REL_ALLOC]: ... to here, to check interface.
11085 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11086 Remove decls. This fixes an "It stinks!".
11088 * alloc.c (which_symbols): Fix alignment issue / type clash.
11090 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11092 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11093 (struct Lisp_Misc_Any): Likewise.
11094 (struct Lisp_Free): Likewise.
11095 * alloc.c (union aligned_Lisp_Symbol): Define.
11096 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
11097 aligned_Lisp_Symbol instead of struct Lisp_Symbol.
11098 (union aligned_Lisp_Misc): Define.
11099 (MARKER_BLOCK_SIZE, struct marker_block): Use union
11100 aligned_Lisp_Misc instead of union Lisp_Misc.
11101 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
11103 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
11105 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11106 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11107 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11108 * s/netbsd.h, s/sol2-6.h:
11109 Remove definition of GC_MARK_STACK, since the default now works.
11110 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11111 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11112 no longer the default.
11113 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11115 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11117 * lread.c (lisp_file_lexically_bound_p):
11118 Fix hang at ";-*-\n" (bug#11238).
11120 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11122 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11123 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

11132 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
11134 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11136 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11138 2012-04-11 Daniel Colascione <dancol@dancol.org>
11140 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11141 against is gone. It's better to use vfork now so that when Cygwin
11142 gains a new, working vfork, we use it automatically (bug#10398).
11144 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11146 * window.c (save_window_save): Obey window-point-insertion-type.

11159 (force_quit_count): New var.
11160 (handle_interrupt): Use it.
11162 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11164 * w32.c (w32_delayed_load): Record the full path of the library
11165 being loaded (bug#10424).
11167 2012-04-09 Glenn Morris <rgm@gnu.org>
11169 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11170 not just in the obarray, before snarfing them. (Bug#11036)
11172 * Makefile.in ($(leimdir)/leim-list.el):
11173 Pass EMACS rather than BUILT_EMACS.
11175 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11177 * process.c (make_process):
11178 * process.h: Add integer `gnutls_handshakes_tried' member to
11181 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
11182 Add convenience `GNUTLS_LOG2i' macro.
11184 * gnutls.c (gnutls_log_function2i): Convenience log function.
11185 (emacs_gnutls_read): Use new log functions,
11186 `gnutls_handshakes_tried' process member, and
11187 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11188 attempts per process (connection).
11190 2012-04-09 Chong Yidong <cyd@gnu.org>
11192 * eval.c (Fuser_variable_p, user_variable_p_eh)
11193 (lisp_indirect_variable): Functions deleted.
11194 (Fdefvar): Caller changed.
11196 * callint.c (Finteractive, Fcall_interactively):
11197 * minibuf.c (Fread_variable): Callers changed.
11199 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11201 * xdisp.c (set_cursor_from_row): If the display string appears in
11202 the buffer at position that is closer to point than the position
11203 after the display string, display the cursor on the first glyph of
11204 the display string. Fixes cursor display when a 'display' text
11205 property immediately follows invisible text. (Bug#11094)
11207 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11209 composite.c: use 'double' consistently
11210 * composite.c (get_composition_id): Use 'double' consistently
11211 instead of converting 'float' to 'double' and vice versa; this is
11212 easier to understand and avoids a GCC warning.
11214 2012-04-09 Glenn Morris <rgm@gnu.org>
11216 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11217 preparation for dumping it with emacs. (Bug#4789)
11218 (leimdir): New variable.
11219 ($(leimdir)/leim-list.el): New rule.
11220 (emacs$(EXEEXT)): Depend on leim-list.el.
11222 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
11223 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
11224 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
11226 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
11228 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
11231 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
11233 * xml.c (init_libxml2_functions) [WINDOWSNT]:
11234 Remove unused local variable.
11236 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11238 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11239 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11240 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11241 objects, as mark_maybe_pointer will catch them otherwise.
11242 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11243 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
11245 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11247 Fix typo that broke non-Windows builds.
11248 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
11250 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11252 Support building on MS-Windows with libxml2.
11254 * makefile.w32-in (OBJ2): Add xml.$(O).
11255 (GLOBAL_SOURCES): Add xml.c.
11256 ($(BLD)/xml.$(O)): New dependency list.
11258 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11259 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11260 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11261 [!WINDOWSNT]: New macros.
11262 (init_libxml2_functions, libxml2_loaded_p): New functions.
11263 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11264 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11265 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11266 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11268 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11269 Call init_libxml2_functions before calling libxml2 functions.
11270 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11272 * emacs.c: Don't include libxml/parser.h.
11273 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11274 xmlCleanupParser directly.
11276 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11278 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11280 * indent.c (Fvertical_motion): If there is a display string at
11281 point, use it.vpos to compute how many lines to backtrack after
11282 move_it_to point. (Bug#11133)
11284 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11286 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11287 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11288 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11289 macros related to unification of CJK characters. For the details,
11290 see the discussion following the message here:
11291 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11293 2012-04-04 Chong Yidong <cyd@gnu.org>
11295 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11297 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11299 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
11300 instead of alloca. (Bug#11138)
11302 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
11304 * w32menu.c (is_simple_dialog): Properly check lisp types.
11307 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11309 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11310 position we get to after a call to move_it_to fails the
11311 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11312 only if we wind up in a string from display property. (Bug#11063)
11314 * window.c (Fdelete_other_windows_internal): Invalidate the row
11315 and column information about mouse highlight, so that redisplay
11316 restores it after reallocating the glyph matrices. (Bug#7464)
11318 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11319 string comes from a `display' text property, use the buffer
11320 position of that property as if we actually saw that position in
11322 (move_it_by_lines): Remove the assertion that
11323 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11324 violated when there's a before-string at the beginning of a line.
11327 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11329 * xdisp.c (append_space_for_newline): If the default face was
11330 remapped, use the remapped face for the appended newline.
11331 (extend_face_to_end_of_line): Use the remapped default face for
11332 extending the face to the end of the line.
11333 (display_line): Call extend_face_to_end_of_line when the default
11334 face was remapped. (Bug#11068)
11336 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11338 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11340 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11342 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11344 2012-03-27 Glenn Morris <rgm@gnu.org>
11346 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11349 2012-03-26 Kenichi Handa <handa@m17n.org>
11351 * dispextern.h (struct glyph): Fix previous change. Change the
11352 bit length of glyphless.ch to 25 (Bug#11082).

11356 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11357 (command_loop_1): Use it; inhibit selection update for
11358 handle-select-window too (Bug#8996).
11360 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11362 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11364 2012-03-25 Kenichi Handa <handa@m17n.org>
11366 * dispextern.h (struct glyph): Change the bit length of
11367 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11369 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11371 * s/ms-w32.h (tzname): Include time.h before redirecting to
11372 _tzname. Fixes the MSVC build. (Bug#9960)
11374 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11376 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11379 * xterm.c (XTread_socket): Only modify handling_signal if
11380 !SYNC_INPUT. (Bug#11080)
11382 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11384 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11385 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11386 when fetching a multibyte character consumes more bytes than
11387 CHAR_BYTES returns, due to unification of CJK characters in
11388 string_char. (Bug#11073)
11390 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11392 * process.c (wait_reading_process_output): Handle pty disconnect
11393 by refraining from sending oneself a SIGCHLD (bug#10933).
11395 2012-03-22 Chong Yidong <cyd@gnu.org>
11397 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11399 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11400 Mark string as coming from a prefix property.

11406 * xfaces.c (Vface_remapping_alist): Doc fix.
11408 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11410 * w32proc.c (Fw32_set_console_codepage)
11411 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
11414 2012-03-20 Chong Yidong <cyd@gnu.org>
11416 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11417 to reflect default non-nil value of redisplay-dont-pause.

11422 it fit in a valid range (Bug#11003).
11424 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11426 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11427 that is not from display property, accept the row as a "cursor
11428 row" if one of the string's character has a non-nil `cursor'
11429 property. Fixes cursor positioning when there are newlines in
11430 overlay strings, e.g. in icomplete.el. (Bug#11035)
11432 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11434 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11436 2012-03-12 Chong Yidong <cyd@gnu.org>
11438 * eval.c (inhibit_lisp_code): Rename from
11439 inhibit_window_configuration_change_hook; move from window.c.
11441 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11442 * window.c (run_window_configuration_change_hook)
11443 (syms_of_window): Callers changed.
11445 2012-03-11 Chong Yidong <cyd@gnu.org>

11451 2012-03-10 Chong Yidong <cyd@gnu.org>
11453 * frame.c (other_visible_frames): Don't assume the selected frame
11454 is visible (Bug#10955).
11456 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11458 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11460 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11462 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11463 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11466 2012-03-03 Glenn Morris <rgm@gnu.org>
11468 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11470 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11472 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11473 position past the first glyph_row that ends at ZV. (Bug#10902)
11474 (redisplay_window, next_element_from_string): Fix typos in
11476 (redisplay_window): Pass to move_it_vertically the margin in
11477 pixels, not in screen lines.
11479 2012-03-02 Glenn Morris <rgm@gnu.org>
11481 * buffer.c (buffer-list-update-hook): Doc fix.
11483 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11485 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11486 push_it before setting up the iterator for the first overlay
11487 string, even if we have an empty string loaded.
11488 (next_overlay_string): If there's an empty string on the iterator
11489 stack, pop the stack. (Bug#10903)
11491 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11493 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11494 Suggested by Stefan Monnier in
11495 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11496 * alloc.c (widen_to_Lisp_Object): New static function.
11497 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11498 and widening them to Lisp_Objects. This would work even if
11499 USE_LSB_TAG is defined and wide integers are used, which might
11500 happen in a future version of Emacs.
11502 2012-02-25 Chong Yidong <cyd@gnu.org>
11504 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11507 * xselect.c (Fx_selection_exists_p): Doc fix.
11508 (x_clipboard_manager_save_all): Print an informative message
11509 before saving to clipboard manager.
11511 2012-02-24 Chong Yidong <cyd@gnu.org>
11513 * keyboard.c (process_special_events): Handle all X selection
11514 requests in kbd_buffer, not just the next one (Bug#8869).
11516 2012-02-23 Chong Yidong <cyd@gnu.org>
11518 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11519 call when setting menu-bar-lines and tool-bar-lines parameters.
11520 (unwind_create_frame_1): New helper function.
11522 * window.c (inhibit_window_configuration_change_hook): New var.

11541 when computing $valmask.
11543 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11544 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11545 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11546 It's useless in that case, and it can cause problems on hosts
11547 that allocate halves of EMACS_INT values separately.
11548 Reported by Dan Horák. Diagnosed by Andreas Schwab in

12170 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12171 verifies glyph row's hash code--we have just reallocated the

12337 is set, removing the need for VIRT_ADDRESS_VARIES.
12338 (PURE_P): Use a more-efficient implementation that needs just one

12355 behave as if the cursor position were at the window margin.
12357 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12358 and the cursor position is out of bounds, behave as if the cursor
12359 position were at the window margin. (Bug#10075)
12361 2011-11-18 Chong Yidong <cyd@gnu.org>
12363 * window.c (Fwindow_combination_limit): Make first argument

12385 compute_line_metrics.
12386 (compute_line_metrics): Call row_hash, instead of computing the
12389 * dispnew.c (verify_row_hash): Call row_hash for computing the
12390 hash code of a row, instead of duplicating code from xdisp.c.
12392 * dispextern.h (row_hash): Add prototype.
12394 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12396 * frame.c (delete_frame): Don't delete the terminal when the last

12445 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12446 with user-defined heap size. Bump the default size of the temacs

12450 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12451 current_matrix and desired_matrix. (Bug#9990)
12452 (verify_row_hash) [XASSERTS]: New function.

12499 Avoid some portability problems by eschewing 'extern inline' functions.
12500 The trivial performance wins aren't worth the portability hassles; see

12552 This is also needed for porting to any host where GC_MARK_STACK is
12553 not GC_MAKE_GCPROS_NOOPS.
12554 (which_symbols): Use it.

12569 * xmenu.c (cleanup_widget_value_tree): New function.
12570 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

12577 (window_box_width, window_box_left, window_box_left_offset)
12578 (window_box_right, window_box_right_offset): Declare extern.
12579 Otherwise, these inline functions do not conform to C99 and
12580 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12581 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12582 * intervals.c (adjust_intervals_for_insertion)
12583 (adjust_intervals_for_deletion): Now extern, because otherwise the

12585 (static_offset_intervals): Remove.
12586 (offset_intervals): Rewrite using the old contents of
12587 static_offset_intervals. The old version didn't conform to C99
12588 because an extern inline function contained a reference to an
12589 identifier with static linkage.

12655 official. Move initialization of image_cache_refcount and
12656 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

12824 (w32font_open_internal, compute_metrics):
12825 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w

12901 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12902 * editfns.c: Rewrite current-time-zone so that it invokes
12903 the equivalent of (format-time-string "%Z") to get the time zone name.
12904 This fixes a bug when the time zone name contains characters that
12905 need converting from the system time locale to Emacs internal format.
12906 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12907 that patch fixed format-time-string to do the conversion, but
12908 I forgot to fix current-time-zone.
12909 (format_time_string): New function, containing most of
12910 what Fformat_time_string used to contain.
12911 (Fformat_time_string): Rewrite in terms of format_time_string.
12912 This doesn't change this function's behavior.
12913 (current-time-zone): Rewrite to use format_time_string.
12914 This fixes the bug reported by Michael Schierl in
12915 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12916 Jason Rumney's 2007-06-07 change worked around this bug, but
12918 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12920 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12922 * xdisp.c (start_display): If the character at POS is displayed
12923 via a display vector, reset IT->current.dpvec_index to zero.
12924 (try_window_reusing_current_matrix): If a line ends in a display
12925 vector or the next line starts in a display vector, continue
12926 redrawing the window even though the character position of
12927 start_row was reached.
12930 2011-10-18 Chong Yidong <cyd@gnu.org>
12932 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12933 with nobreak-char-display too.
12935 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12937 Fix part 3 of bug#9771.
12938 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12939 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12940 non-neutral characters if the current character is a paragraph
12941 separator (a.k.a. Newline). This avoids running the same
12942 expensive loop twice, once when we consume the preceding newline
12943 and the other time when the line actually needs to be displayed.
12944 Avoid the loop when we see neutrals on the base embedding level
12945 following a character whose directionality is the same as the
12946 paragraph's. This avoids running the expensive loop when a line
12947 ends in a long sequence of neutrals, like control characters.
12948 Add assertion against STRONG_AL type. Slightly rearrange code
12949 that determines the type of a neutral given the first non-neutral
12951 (bidi_level_of_next_char): Set next_en_pos to zero when
12952 invalidating its info.
12954 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12956 * xdisp.c (push_display_prop): Determine whether to record string
12957 or buffer position by IT->string, not by IT->method. Allow
12958 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12959 (move_it_vertically_backward): Don't look for character position
12960 immediately after the newline when in a continuation line.
12963 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12965 * window.c (coordinates_in_window): Rewrite and delabelize
12966 vertical border check. (Bug#5357) (Bug#9618)
12968 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12970 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12971 errors in XSetWindowBorder (bug#9310).
12973 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12975 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12976 avoid crash when xmalloc overrun checking is enabled.
12978 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12980 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12981 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12982 cursor motion with <left> and <right> arrow keys.
12984 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12985 some callers set that themselves.
12987 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12989 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12990 display string and the previous row comes from the same string and
12991 is empty. (Bug#9739) (Bug#9738)
12993 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12995 * doc.c (get_doc_string): Encode file name (bug#9735).
12997 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12999 * bidi.c (bidi_level_of_next_char):
13000 * xdisp.c (get_visually_first_element): Remove old incorrect
13001 comments regarding the Unicode Line Separator character.
13003 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13005 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13007 * alloc.c (Fgc_status): Do not access beyond zombies array
13008 boundary if nzombies > MAX_ZOMBIES.
13009 * alloc.c (dump_zombies): Add missing format specifier.
13011 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13013 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13014 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13016 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13017 Some packages use them to denote characters with modifiers.
13019 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13021 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13022 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13023 matching a pp-number. Rename parameter var to var1.
13025 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13027 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13029 2011-10-08 Glenn Morris <rgm@gnu.org>
13031 * callint.c (Fcall_interactively): Give a more explicit error for the
13032 'c' case with a non-character input. (Bug#8479)
13034 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13036 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13038 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13039 lines that are hscrolled on the left.
13041 * dispnew.c (buffer_posn_from_coords): Account for a possible
13042 presence of header-line. (Bug#4426)
13044 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13046 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13047 Don't advertise functionality which we discourage or doesn't work.
13049 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13051 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13052 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13053 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13054 this makes Emacs dump core during garbage collection on rare
13055 occasions. sizeof is obviously inferior to offsetof here, so
13056 stick with offsetof.
13057 (GC_POINTER_ALIGNMENT): New macro.
13058 (mark_memory): Omit 3rd (offset) arg; caller changed.
13059 Don't assume EMACS_INT alignment is the same as pointer alignment.
13061 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13063 * keyboard.c (read_key_sequence_remapped): New var.
13064 (read_key_sequence): Compute remapping in the right buffer.
13065 (command_loop_1): Use read_key_sequence's remapping directly.
13067 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13069 * dired.c (file_name_completion): Don't expand file name.
13070 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13071 before checking file name handler.
13073 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13074 they've been requested explicitly (bug#9591).
13076 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13078 * keymap.c (Fsingle_key_description): Use make_specified_string
13079 instead of build_string to build string from push_key_description.
13082 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13084 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13085 This fixes a Y2038 bug on 64-bit hosts.
13086 * buffer.c (reset_buffer):
13087 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13088 (Fclear_buffer_auto_save_failure):
13089 Use 0, not -1, to represent an unset failure time, since time_t
13090 might not be signed.
13092 Remove dependency on glibc malloc internals.
13093 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13094 Move back here from lisp.h, but with their new implementations.
13095 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13096 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13097 * charset.c (charset_table_init): New static var.
13098 (syms_of_charset): Use it instead of xmalloc. This removes a
13099 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13100 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13101 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13102 Move back to alloc.c.
13103 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13104 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13106 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13108 * nsterm.m (windowDidResize): Call x_set_window_size only when
13109 ns_in_resize is true. Otherwise set pixelwidth/height and
13110 call change_frame_size (Bug#9628).
13112 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13114 Port --enable-checking=all to Fedora 14 x86-64.
13115 * charset.c (syms_of_charset): Also account for glibc malloc's
13116 internal overhead when calculating the initial malloc maximum.
13118 Port --enable-checking=all to Fedora 14 x86.
13119 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13121 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13122 (overrun_check_realloc, overrun_check_free):
13123 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13124 That way, xmalloc returns a properly-aligned pointer even if
13125 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13126 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13127 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13128 into account when calculating the initial malloc maximum.
13129 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13130 Move here from alloc.c, so that charset.c can use it too.
13131 Properly align; the old code wasn't right for common 32-bit hosts
13132 when configured with --enable-checking=all.
13133 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13134 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13136 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13138 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13141 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13143 * xdisp.c (compute_display_string_end): If there's no display
13144 string at CHARPOS, return -1.
13146 * bidi.c (bidi_fetch_char): When compute_display_string_end
13147 returns a negative value, treat the character as a normal
13148 character not covered by a display string. (Bug#9624)
13150 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13152 * lread.c (Fread_from_string): Fix typo in docstring.
13154 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13156 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13157 newline, reseat the iterator instead of bidi-iterating there one
13158 character at a time. (Bug#9610)
13159 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13160 TO_CHARPOS if the bidi iterator is at base embedding level.
13162 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13164 * lread.c (readevalloop): Use correct code for NBSP.
13165 (read1): Likewise. (Bug#9608)
13167 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13169 * dbusbind.c (Fdbus_register_signal): When service is not
13170 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13172 2011-09-25 Glenn Morris <rgm@gnu.org>
13174 * buffer.c (truncate-lines): Doc fix.
13176 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13178 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13179 (Fset_window_next_buffers): Doc fix.
13181 2011-09-24 Glenn Morris <rgm@gnu.org>
13183 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13185 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13187 Fix minor problems found by static checking.
13188 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13189 * indent.c (Fvertical_motion): Fix == vs = typo.
13191 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13193 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13194 Default value is now t. Doc fix.
13196 * indent.c (Fvertical_motion): Compute and apply the overshoot
13197 logic when moving up, not only when moving down. Fix the
13198 confusing name and values of the it_overshoot_expected variable;
13199 logic changes accordingly. (Bug#9254) (Bug#9549)
13201 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13202 CHARPOS is covered by a display string which includes newlines.
13203 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13204 is covered by a display string with embedded newlines.
13206 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13208 * dbusbind.c (Fdbus_register_signal): Add match rule to
13209 Vdbus_registered_objects_table. (Bug#9581)
13210 (Fdbus_register_method, Vdbus_registered_objects_table):
13213 2011-09-24 Jim Meyering <meyering@redhat.com>
13215 do not ignore write error for any output size
13216 The previous change was incomplete.
13217 While it makes emacs --batch detect the vast majority of stdout
13218 write failures, errors were still ignored whenever the output size is
13219 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13220 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13221 && echo FAIL: ignored write error
13222 FAIL: ignored write error
13223 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13224 && echo FAIL: ignored write error
13225 FAIL: ignored write error
13226 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13228 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13230 * emacs.c (Fkill_emacs): In noninteractive mode exit
13231 non-successfully if a write error occurred on stdout. (Bug#9574)
13233 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13235 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13238 * dispextern.h (struct it): Update the comment documenting what
13241 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13243 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13244 a display string, extend search for cursor position to end of row.
13245 (find_row_edges): If the row ends in a newline from a display
13246 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13247 Handle the case of a display string with multiple newlines.
13248 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13249 non-empty line. Fixes confusing cursor motion with arrow keys at
13250 the beginning of a line that starts with whitespace.
13252 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13254 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13257 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13259 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13260 boolean (Bug#9154).
13262 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13264 * xdisp.c (display_line): Record maximum and minimum buffer
13265 positions even if no glyphs were produced (e.g., by a zero-width
13266 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13267 buffer positions that will be removed from the glyph row because
13269 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13270 column is beyond frame width: don't subtract 1 "pixel" when
13271 computing width of the stretch.
13272 (reseat_at_next_visible_line_start): Undo the change made on
13273 2011-09-17 that saved paragraph information and restored it after
13274 the call to `reseat'. (Bug#9545)
13276 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13278 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13279 and turn window cursor on if cleared (Bug#9415).
13281 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13283 * search.c (boyer_moore): Take unibyte characters from pattern
13284 literally. (Bug#9458)
13286 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13288 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13290 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13292 Fix minor problem found by static checking.
13293 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13294 initialized, to pacify gcc -Wuninitialized.
13296 * fileio.c: Report proper errno when syscall falls.
13297 (Finsert_file_contents): Save and restore errno,
13298 so that report_file_error outputs the correct diagnostic.
13299 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13301 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13303 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13305 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13307 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13308 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13310 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13312 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13313 about the current paragraph and restore it after the call to reseat.
13315 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13316 (bidi_find_paragraph_start): Search back for paragraph beginning
13317 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13318 (bidi_move_to_visually_next): Only trigger paragraph-related
13319 computations when the last character is a newline or at EOB, not
13320 just any NEUTRAL_B. (Bug#9470)
13322 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13323 truncated lines if point is covered by a display string. (Bug#9524)
13325 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13327 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13328 (cons_to_x_long): New function.
13329 (lisp_data_to_selection_data): Use it. Correct the test for
13330 short-versus-long data; it was negated. Break out of vector
13331 loop, for efficiency, when a long datum is discovered.
13333 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13335 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

13356 * composite.c (composition_update_it, get_composition_id):
13357 * xdisp.c (get_next_display_element)
13358 (fill_composite_glyph_string): Add comments about special meaning
13359 of TAB characters in a composition.
13361 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13363 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13364 This occurs when processing a multibyte format.
13365 Problem reported by Wolfgang Jenker.
13367 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13369 * xdisp.c (try_cursor_movement): Only check for exact match if
13370 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13372 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13374 Remove unused external symbols.
13375 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13376 * xdisp.c (calc_pixel_width_or_height): Now static.
13377 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

13382 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13384 * xselect.c: Use signed conversions more consistently (Bug#9498).
13385 (selection_data_to_lisp_data): Assume incoming selection data are
13386 signed integers, not unsigned. This is to be consistent with
13387 outgoing selection data, which was modified to use signed integers
13388 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13389 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13390 expects long, not unsigned long.

13400 * frame.c (Fother_visible_frames_p): Function deleted.
13402 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13404 * indent.c (compute_motion): Process display vector front to back
13405 rather than the other way around. (Bug#2496)
13407 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13409 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13411 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13413 * minibuf.c (Fread_from_minibuffer): Doc fix.
13415 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13417 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13418 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13420 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13422 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13423 value for non-existent files.
13425 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13427 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13428 set its "size" to -1. This will set the modtime_size field of
13429 the corresponding buffer to -1, which is what
13430 verify-visited-file-modtime expects for files that do not exist.
13433 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13435 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13437 * lisp.h: ... from here. push_key_description is no longer
13438 defined in keyboard.c, so its declaration should not be in
13439 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13440 logically belongs with push_key_description.
13442 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13444 * buffer.h: Include <sys/types.h> instead of <time.h>.
13445 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13446 Problem reported by Herbert J. Skuhra.
13448 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13450 * xml.c (parse_region): Make the parsing work for
13451 non-comment-starting XML files again (bug#9144).
13453 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13455 * image.c (gif_load): Fix calculation of bottom and right corner.
13458 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13460 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13461 redisplay in small windows.
13463 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13465 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13467 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13469 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13470 Operate on live windows only.
13472 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13474 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13476 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13478 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13479 only under bidi iteration.
13481 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13483 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13485 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13487 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13488 Without this fix, the command to link temacs failed due to an
13489 undefined symbol __builtin_isnan. This is because
13490 /usr/include/iso/math_c99.h #defines isnan(x) to
13491 __builtin_isnan(x), but the bundled gcc, which identifies itself
13492 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13494 * floatfns.c (isnan): #undef, and then #define to a clone of
13496 (Fisnan): Always define, since it's always available now.
13497 (syms_of_floatfns): Always define isnan at the Lisp level.
13499 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13501 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13503 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13505 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13506 The previous code assumed that file offsets (off_t values) fit in
13507 EMACS_INT variables, which is not true on typical 32-bit hosts.
13508 The code messed up by falsely reporting buffer overflow in cases
13509 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13510 when "big" contains more than 2**29 bytes, even though this
13511 inserts just one byte and does not overflow the buffer.
13512 (Finsert_file_contents): Store file offsets as off_t
13513 values, not as EMACS_INT values. Check for overflow when
13514 converting between EMACS_INT and off_t. When checking for
13515 buffer overflow or for overlap, take the offsets into account.
13516 Don't use EMACS_INT for small values where int suffices.
13517 When checking for overlap, fix a typo: ZV was used where
13518 ZV_BYTE was intended.
13519 (Fwrite_region): Don't assume off_t fits into 'long'.
13520 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13522 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13524 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13526 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13528 sprintf-related integer and memory overflow issues (Bug#9412).
13530 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13531 (esprintf, exprintf, evxprintf): New functions.
13532 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13533 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13534 (modify_event_symbol): Do not assume that the length of
13535 name_alist_or_stem is safe to alloca and fits in int.
13536 (Fexecute_extended_command): Likewise for function name and binding.
13537 (Frecursion_depth): Wrap around reliably on integer overflow.
13538 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13539 since some callers pass EMACS_INT values.
13540 (Fsingle_key_description): Don't crash if symbol name contains more
13541 than MAX_ALLOCA bytes.
13542 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13543 (get_minibuffer): Arg is now EMACS_INT, not int.
13544 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13545 (esprintf, exprintf, evxprintf): New decls.
13546 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13548 * dbusbind.c (signature_cat): New function.
13549 (xd_signature, Fdbus_register_signal):
13550 Do not overrun buffer; instead, report string overflow.
13552 * dispnew.c (add_window_display_history): Don't overrun buffer.
13553 Truncate instead; this is OK since it's just a log.
13555 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13556 even if the time zone offset is outlandishly large.
13557 Don't mishandle offset == INT_MIN.
13559 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13560 when creating daemon; the previous buffer-overflow check was incorrect.
13562 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13563 which has the guts of the old verror function.
13565 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13566 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13568 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13569 (font_unparse_xlfd): Don't blindly alloca long strings.
13570 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13571 fits in int, when using sprintf. Use single snprintf to count
13572 length of string rather than counting it via multiple sprintfs;
13573 that's simpler and more reliable.
13574 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13575 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13576 sprintf, in case result does not fit in int.
13578 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13579 (fontset_from_font): Print it.
13581 * frame.c (tty_frame_count): Now printmax_t, not int.
13582 (make_terminal_frame, set_term_frame_name): Print it.
13583 (x_report_frame_params): In X, window IDs are unsigned long,
13584 not signed long, so print them as unsigned.
13585 (validate_x_resource_name): Check for implausibly long names,
13586 and don't assume name length fits in 'int'.
13587 (x_get_resource_string): Don't blindly alloca invocation name;
13588 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13591 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13592 (xg_check_special_colors, xg_set_geometry):
13593 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13595 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13596 Use esprintf, not sprintf, in case result does not fit in int.
13598 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13599 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13600 it as a large positive number.
13601 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13602 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13604 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13605 in case result does not fit in int.
13607 * print.c (float_to_string): Detect width overflow more reliably.
13608 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13609 buffer overrun. Don't assume list length fits in 'int'. Treat
13610 print length of 0 as 0, not as infinity; to be consistent with other
13611 uses of print length in this function. Don't overflow print length
13612 index. Don't assume hash table size fits in 'long', or that
13613 vectorlike size fits in 'unsigned long'.
13615 * process.c (make_process): Use printmax_t, not int, to format
13616 process-name gensyms.
13618 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13620 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13621 to avoid potential buffer overrun.
13623 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13624 if X resource line is longer than 512 bytes.
13626 * xfns.c (x_window): Make sprintf buffer a bit bigger
13627 to avoid potential buffer overrun.
13629 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13631 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13633 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13635 Integer overflow fixes for scrolling, etc.
13636 Without these, Emacs silently mishandles large integers sometimes.
13637 For example, "C-u 4294967297 M-x recenter" was treated as if
13638 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13640 * xdisp.c (try_window_id): Check Emacs fixnum range before
13641 converting to 'int'.
13643 * window.c (window_scroll_line_based, Frecenter):
13644 Check that an Emacs fixnum is in range before assigning it to 'int'.
13645 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13646 values converted from Emacs fixnums.
13647 (Frecenter): Don't wrap around a line count if it is out of 'int'
13648 range; instead, treat it as an extreme value.
13649 (Fset_window_configuration, compare_window_configurations):
13650 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13652 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13653 that can exceed INT_MAX. Check that EMACS_INT value is in range
13654 before assigning it to the (possibly-narrower) index.
13655 (match_limit): Don't assume that a fixnum can fit in 'int'.
13657 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13660 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13661 (Fvertical_motion): Don't wrap around LINES values that don't fit
13662 in 'int'. Instead, treat them as extreme values. This is good
13663 enough for windows, which can't have more than INT_MAX lines anyway.
13665 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13667 * Require libxml/parser.h to avoid compilation warning.
13669 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13671 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13672 since this reportedly can destroy thread storage.
13674 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13676 * syntax.c (find_defun_start): Update all cache variables if
13677 exiting early (Bug#9401).
13679 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13681 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13683 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13684 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13685 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13687 * term.c (tty_append_glyph): New function.
13688 (produce_stretch_glyph): Static function and its prototype deleted.
13690 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13693 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13695 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13696 when checking :margin (Bug#9390).
13697 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13698 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13699 so that the name doesn't mislead. All uses changed.
13701 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13703 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13706 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13708 * xdisp.c (move_it_to): Don't bail out early when reaching
13709 position beyond to_charpos, if we are scanning backwards.
13710 (move_it_vertically_backward): When DY == 0, make sure we get to
13711 the first character in the line after the newline.
13713 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13715 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13716 (ccl_driver): Do not generate an out-of-range pointer.
13717 (Fccl_execute_on_string): Remove unnecessary check for
13718 integer overflow, noted by Stefan Monnier in
13719 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13720 Remove a FIXME that didn't need fixing.
13721 Simplify the newly-introduced buffer reallocation code.
13723 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13725 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13727 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13729 Integer and memory overflow issues (Bug#9196).
13731 * doc.c (get_doc_string): Rework so that
13732 get_doc_string_buffer_size is the actual buffer size, rather than
13733 being 1 less than the actual buffer size; this makes xpalloc more
13736 * image.c (x_allocate_bitmap_record, cache_image):
13737 * xselect.c (Fx_register_dnd_atom):
13738 Simplify previous changes by using xpalloc.
13740 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13741 since either will do and ptrdiff_t is convenient with xpalloc.
13743 * charset.c (charset_table_size)
13744 (struct charset_sort_data.priority): Now ptrdiff_t.
13745 (charset_compare): Don't overflow if priorities differ greatly.
13746 (Fsort_charsets): Don't assume list length fits in int.
13747 Check for size-calculation overflow when allocating sort data.
13748 (syms_of_charset): Allocate an initial charset table that is
13749 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13751 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13753 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13754 The actual value is always <= INT_MAX, and leaving it unsigned made
13755 overflow checking harder.
13757 * dispextern.h (struct glyph_matrix.rows_allocated)
13758 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13759 with xpalloc. The values are still always <= INT_MAX.
13761 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13763 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13764 (SAFE_NALLOCA): New macro.
13766 * region-cache.c (struct boundary.pos, find_cache_boundary)
13767 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13768 (set_cache_region, invalidate_region_cache)
13769 (revalidate_region_cache, know_region_cache, region_cache_forward)
13770 (region_cache_backward, pp_cache):
13771 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13772 so that ptrdiff_t * can be passed to xpalloc.
13773 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13774 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13775 (pp_cache): Don't assume cache_len fits in int.
13776 * region-cache.h: Adjust extern decls to match.
13778 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13779 EMACS_INT, since either will do, for xpalloc.
13781 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13782 (xnmalloc, xnrealloc, xpalloc): New functions.
13784 * bidi.c (bidi_shelve_header_size): New constant.
13785 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13786 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13788 * bidi.c (bidi_cache_shrink):
13789 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13791 Don't update size of array until after memory allocation succeeds,
13792 because xmalloc/xrealloc may not return.
13793 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13794 now that we have proper integer overflow checking.
13795 (record_overlay_string, overlay_strings): Catch overflows when
13796 calculating size of overlay_str_buf.
13798 * callproc.c (Fcall_process): Check for size overflow when
13799 calculating size of args2.
13800 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13801 Normally we prefer signed values, but sticking with ptrdiff_t would
13802 require adding more-complicated checks.
13804 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13805 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13806 Redo buffer-overflow calculations to avoid integer overflow.
13807 Add a FIXME comment where memory seems to be over-allocated.
13809 * character.c (Fstring): Check for size-calculation overflow.
13811 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13812 unnecessary integer overflow. Check for size overflow.
13813 (encode_coding_object): Don't update size until xmalloc succeeds.
13815 * composite.c (get_composition_id): Check for overflow in glyph
13816 length calculations.
13818 Integer and memory overflow fixes for display code.
13819 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13820 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13821 (scrolling_window): Check for overflow in size calculations.
13822 (line_draw_cost, realloc_glyph_pool, add_row_entry):
13823 Don't assume glyph table len fits in int.
13824 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
13825 (row_table_size): Now ptrdiff_t, not int.
13826 (scrolling_window): Avoid overflow in size calculations.
13827 Don't update size until allocation succeeds.
13828 * fns.c (concat): Check for overflow in size calculations.
13829 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
13830 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
13831 (NEXT_ALMOST_PRIME_LIMIT): New constant.
13833 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13834 (get_doc_string): Check for size calculation overflow.
13835 Don't update size until allocation succeeds.
13836 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13837 EMACS_INT, where ptrdiff_t will do.
13838 (Fsubstitute_command_keys): Check for string overflow.
13840 * editfns.c (set_time_zone_rule): Don't assume environment length
13842 (message_length): Now ptrdiff_t, not int.
13843 (Fmessage_box): Don't update size until allocation succeeds.
13844 Don't assume message length fits in int.
13845 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13847 * emacs.c (main): Do not reallocate argv, since there is a null at
13848 the end that can be overwritten, and this way there's no need to
13849 worry about size-calculation overflow.
13850 (sort_args): Check for size-calculation overflow.
13852 * eval.c (init_eval_once, grow_specpdl): Don't update size until

13859 (x_set_alpha): Do not assume XINT fits in int.
13861 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13862 This is for the members text_lines, text_cols, total_lines, total_cols,
13863 where the system imposes an 'int' limit.
13865 * fringe.c (Fdefine_fringe_bitmap):

13872 Check for size-calculation overflow.
13873 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13874 do, as we prefer signed integers.

13930 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13931 for command line length. Do not attempt to address one before the
13932 beginning of an array, as that's not portable.
13934 * term.c (max_frame_lines): Remove; unused.

13962 Check for size calculation overflow.
13963 (cache_face): Treat size calculation overflows as if they were
13964 memory exhaustion (the usual treatment), rather than aborting.
13966 * xfns.c (x_encode_text, x_set_name_internal)
13967 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13968 sizes, since they can exceed INT_MAX in size. Check for size
13969 calculation overflow.
13971 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
13972 (xg_select): Check for size calculation overflow.
13973 Don't update size until alloc done.
13975 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13976 as sprintf is limited to int lengths.
13978 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13979 (X_LONG_MIN): New macros.
13980 Use them to make the following changes clearer.
13981 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13982 This change doesn't affect the value now, but it may help remind
13983 future maintainers not to raise the value too much later.
13984 (SELECTION_QUANTUM): Remove, replacing with ...
13985 (selection_quantum): ... new function, which avoids overflow.
13987 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13988 assumption that selection length fits in 'int'.

14005 Don't store size until memory allocation succeeds.
14006 (x_get_window_property): Plug memory leak on memory exhaustion.
14007 Don't double-block input; malloc is safe here. Don't assume 2**34
14008 - 4 fits in unsigned long. Add an xassert to check
14009 XGetWindowProperty overflow. Be more careful about overflow
14010 calculations, and distinguish size from memory overflow better.
14011 (receive_incremental_selection): When tracing, don't assume
14012 unsigned int is less than INT_MAX.
14013 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14016 in the range -65535 through -1 fit in an X unsigned short.
14017 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14018 result parameters unless successful. Rely on cons_to_unsigned
14019 to report problems with elements; the old code wasn't right anyway.
14020 (x_check_property_data): Check for int overflow; we cannot use
14021 a wider type due to X limits.
14022 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

14054 * lisp.h (hash_lookup, hash_put):
14055 * minibuf.c (Ftest_completion):
14056 Use ptrdiff_t for hash table indexes, not int (which is too
14057 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14058 32-bit --with-wide-int hosts).
14060 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14061 Add a FIXME comment about memory leaks.
14062 (syms_of_charset): Don't assume xmalloc returns.

14069 with outlandish widths.
14070 * character.h (sanitize_tab_width): Rename from sanitize_width,
14071 now that we have two such functions. All uses changed.

14089 * xterm.c: Don't go over XClientMessageEvent limit.
14090 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14091 (x_send_scroll_bar_event): Likewise. Check that the size does not
14092 exceed limits imposed by XClientMessageEvent, as well as the usual
14093 ptrdiff_t and size_t limits.
14095 * keyboard.c: Overflow, signedness and related fixes.
14096 (make_lispy_movement): Use same integer type in forward decl
14097 that is used in the definition.
14098 (read_key_sequence, keyremap_step):
14099 Change bufsize argument back to int, undoing my 2011-03-30 change.
14100 We prefer signed types, and int is wide enough here.
14101 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14102 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14103 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14104 length, not size_t. Use ptrdiff_t for index, not int.
14105 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14106 possibility of integer overflow.
14108 Overflow, signedness and related fixes for images.

14134 Prefer int to unsigned where either will do.
14135 (tiff_handler): New function, combining the cores of the
14136 old tiff_error_handler and tiff_warning_handler.
14137 This function is rewritten to use vsnprintf and thereby avoid
14138 stack buffer overflows. It uses only the features of vsnprintf
14139 that are common to both POSIX and native Microsoft.
14140 (tiff_error_handler, tiff_warning_handler): Use it.
14141 (tiff_load, gif_load, imagemagick_load_image):
14142 Don't assume :index value fits in 'int'.
14143 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14144 (imagemagick_load_image): Check that crop parameters fit into
14145 the integer types that MagickCropImage accepts. Don't assume
14146 Vimagemagick_render_type has a nonnegative value. Don't assume
14147 size_t fits in 'long'.
14148 (gs_load): Use printmax_t to print the widest integers possible.

14161 handle_single_display_spec, not just 1 or zero.
14162 (handle_single_display_spec): If the display spec is of the form
14163 `(space ...)', and specifies display in the text area, return 2
14165 (try_cursor_movement): Check for the need to scroll more
14166 accurately, and prefer exact match for point under bidi.
14167 Don't advance `row' beyond the last row of the window.

14185 buffers, return left-to-right.
14186 (set_cursor_from_row): Consider candidate row a win if its glyph
14187 represents a newline and point is on that newline. Fixes cursor
14188 positioning on the newline at EOL of R2L text within L2R
14189 paragraph, and vice versa.
14190 (try_cursor_movement): Check continued rows, in addition to
14191 continuation rows. Fixes unwarranted scroll when point enters a
14192 continued line of R2L text within an L2R paragraph, or vice versa.
14193 (cursor_row_p): Consider the case of point being equal to
14194 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14195 from the end of a short line to the beginning of a continued line
14196 of R2L text within L2R paragraph.
14197 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

14220 * xdisp.c (redisplay_window): When computing centering_position,
14221 account for the height of the header line. (Bug#8874)
14223 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14224 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14225 candidate is selected by the mouse, and that candidate has a
14226 composed character under the mouse.
14228 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14229 coordinates reported by pos-visible-in-window-p for a composed
14230 character in column zero.
14232 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14236 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14238 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14239 consider it a hit if to_charpos is anywhere in the range of the
14240 composed buffer positions.
14242 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14244 * image.c (gif_load): Don't assume that each subimage has the same
14245 dimensions as the base image. Handle disposal method that is
14246 "undefined" by the gif spec (Bug#9335).
14248 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14250 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14255 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14256 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14257 from an Org mode buffer to a Speedbar frame.
14259 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14260 a composition, take its buffer position from IT->cmp_it.charpos.
14261 Fixes cursor positioning at the beginning of a line that begins
14262 with a composed character.
14264 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14266 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14267 character bidirectional type, use STRONG_L instead. Fixes crashes
14268 in a buffer produced by `describe-categories'.
14270 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14271 members before the level stack, so they would be saved and
14272 restored when copying iterator state. Fixes incorrect reordering
14273 around TABs covered by display properties.
14275 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14277 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14288 has no `load' handler, try opening the file locally. (Bug#9311)
14290 2011-08-16 Ken Brown <kbrown@cornell.edu>
14292 * gmalloc.c: Expand comment.
14294 2011-08-16 Eli Zaretskii <eliz@gnu.org>
14296 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
14297 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
14299 2011-08-16 Ken Brown <kbrown@cornell.edu>
14301 Fix memory allocation problems in Cygwin build (Bug#9273).
14303 * unexcw.c ( __malloc_initialized): Declare external variable.
14304 (fixup_executable): Force the dumped emacs to reinitialize malloc.
14306 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
14308 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
14310 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
14311 in the static heap.
14312 [CYGWIN] (special_realloc): New function.
14313 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
14314 requests to realloc storage in the static heap.
14316 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
14318 * bidi.c (bidi_initialize): Remove unused local.
14320 2011-08-15 Eli Zaretskii <eliz@gnu.org>
14323 * biditype.h: Remove file.
14324 * makefile.w32-in ($(BLD)/bidi.$(O)):
14325 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
14327 * dispextern.h: Fix a typo in the comment to bidi_type_t.
14329 * chartab.c: Improve commentary for the uniprop_table API.
14331 * bidi.c (bidi_paragraph_init): Support zero value of
14332 bidi_ignore_explicit_marks_for_paragraph_level.
14333 (bidi_initialize): Use uniprop_table instead of including
14334 biditype.h and bidimirror.h.
14336 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
14337 coordinates of the iterator when restoring from ppos_it.
14340 2011-08-14 Kenichi Handa <handa@m17n.org>
14342 * process.c (create_process): Call setup_process_coding_systems
14343 after the pid of the process is set to -1 (Bug#8162).
14345 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14347 * xdisp.c (move_it_in_display_line_to): Don't invoke
14348 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14349 ppos_it. Fixes vertical cursor motion when line beginning is
14350 covered by an image. (Bug#9296)
14352 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14354 * nsterm.h (ns_run_ascript): Declare.
14355 (NSAPP_DATA2_RUNASSCRIPT): Define.
14357 * nsfns.m (as_script, as_result, as_status): New static variables.
14358 (ns_run_ascript): New function.
14359 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14360 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14361 the event loop. Get status from as_status (Bug#7276).
14363 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14364 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14365 the event loop (Bug#7276).
14367 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14369 * gnutls.c (QCgnutls_bootprop_priority)
14370 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14371 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14372 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14373 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14374 (QCgnutls_bootprop_verify_hostname_error)
14375 (QCgnutls_bootprop_callbacks_verify): Rename from
14376 Qgnutls_bootprop_..., all uses changed.
14378 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
14381 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
14383 * xfaces.c (Qframe_set_background_mode): Now static.
14384 * dispextern.h (Qframe_set_background_mode): Remove decl.
14386 * process.c (Fnetwork_interface_info): Declare local only if needed.
14388 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
14390 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14391 (Fnetwork_interface_list): Allocate in increments of bytes instead
14392 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14393 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14395 (struct ifflag_def): notrailers is smart on OSX.
14396 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14397 Get hardware address with getifaddrs if available.
14399 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14401 * xdisp.c (iterate_out_of_display_property): xassert that
14402 IT->position is set to within IT->object's boundaries. Break from
14403 the loop as soon as EOB is reached; avoids infloops in redisplay
14404 when IT->position is set up wrongly due to some bug.
14405 Set IT->current to match the bidi iterator unconditionally.
14406 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14407 entry. Force push_it to save on the stack the current
14408 buffer/string position, to be restored by pop_it. Fix flags in
14409 the iterator structure wrt the object coming from a display
14410 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14411 properties. (Bug#9284)
14413 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14415 * fontset.c (fontset_get_font_group): Add proper type checks.
14418 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14420 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
14421 and LC_VERSION_MIN_MACOSX.
14422 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
14423 (dump_it) [LC_FUNCTION_STARTS]: Use it.
14425 2011-08-08 Eli Zaretskii <eliz@gnu.org>
14427 * xdisp.c (forward_to_next_line_start): Allow to use the
14428 no-display-properties-and-no-overlays under bidi display.
14429 Set disp_pos in the bidi iterator to avoid searches for display
14430 properties and overlays.
14432 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14434 * editfns.c (Fset_time_zone_rule): Document relationship with the
14437 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
14438 the font entity extracted from the cache (Bug#8109).
14440 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14442 * composite.c (autocmp_chars): Don't reset point. That is done by
14443 restore_point_unwind (Bug#5984).
14445 2011-08-07 Juri Linkov <juri@jurta.org>
14447 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14448 to show the arg `TIME' instead of `TIMEVAL'.
14450 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14452 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14453 display property strides EOL and includes a newline, as in
14454 longlines-mode. (Bug#9254)
14455 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14456 word-wrap under bidirectional display. (Bug#9224)
14458 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14459 is non-zero, even if the data buffer is NULL. Fixes a crash in
14460 vertical-motion with longlines-mode. (Bug#9254)
14462 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14464 * bidi.c <bidi_cache_total_alloc>: Now static.
14465 (bidi_initialize): Initialize bidi_cache_total_alloc.
14467 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14470 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14471 amount allocated this far in `bidi_cache_total_alloc'.
14472 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14473 non-zero, only free the data buffer without restoring the cache
14474 contents. All callers changed.
14476 * dispextern.h (bidi_unshelve_cache): Update prototype.
14478 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14479 (move_it_in_display_line, move_it_to)
14480 (move_it_vertically_backward, move_it_by_lines): Replace the call
14481 to xfree to an equivalent call to bidi_unshelve_cache.
14482 (move_it_in_display_line_to): Fix logic of returning
14483 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14485 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14487 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14488 came from a string character with a `cursor' property. (Bug#9229)
14490 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14492 * Makefile.in (LIB_PTHREAD): New variable.
14493 (LIBES): Add LIB_PTHREAD (Bug#9216).
14495 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14496 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14498 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14500 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14502 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14504 * xterm.c (x_find_topmost_parent): New function.
14505 (x_set_frame_alpha): Find topmost parent window with
14506 x_find_topmost_parent and set the property there also (bug#9181).
14507 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14509 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14511 * callproc.c (Fcall_process): Avoid vfork clobbering
14512 the local vars buffer, coding_systems, current_dir.
14514 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14516 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14518 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14520 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14521 so that it is not optimized away.
14523 * xdisp.c (compute_display_string_pos): Remove unused local.
14525 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14527 Fix slow cursor motion and scrolling in large buffers with
14528 selective display, like Org Mode buffers. (Bug#9218)
14530 * dispextern.h (struct bidi_it): New member disp_prop_p.
14532 * xdisp.c: Remove one-slot cache of display string positions.
14533 (compute_display_string_pos): Accept an additional argument
14534 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14535 for a display string or property. If found, set DISP_PROP_P
14538 * bidi.c (bidi_fetch_char): Accept an additional argument
14539 DISP_PROP_P, and pass it to compute_display_string_pos.
14540 Only handle text covered by a display string if DISP_PROP_P is returned
14541 non-zero. All callers of bidi_fetch_char changed.
14543 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14545 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14547 2010-12-03 Don March <don@ohspite.net>
14549 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14550 last character M-[char] is translated to ESC [char] (bug#7541).
14552 2011-08-02 Kenichi Handa <handa@m17n.org>
14554 * lisp.h (uniprop_table): Extern it.
14556 * chartab.c (uniprop_table): Make it non-static.
14558 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14560 * xdisp.c (forward_to_next_line_start): Accept additional argument
14561 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14563 (reseat_at_next_visible_line_start): Use the bidi iterator state
14564 returned by forward_to_next_line_start to restore the state of
14565 it->bidi_it after backing up to previous newline. (Bug#9212)
14567 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14569 * regex.c (re_comp): Protoize.
14570 (re_exec): Fix return type.
14571 (regexec): Fix type of `ret'. (Bug#9203)
14573 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14575 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14576 This is needed if max-image-size is a floating-point number.
14578 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14580 * print.c (print_object): Print empty symbol as ##.
14582 * lread.c (read1): Read ## as empty symbol.
14584 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14586 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14587 setting frame foreground color (Bug#9175).
14588 (x_set_background_color): Likewise.
14590 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14591 contents (Bug#9176).
14592 (EmacsTooltip -init): Remove bezels and add shadows to
14595 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14596 or scroll bar (Bug#8470).
14598 * nsfont.m (nsfont_open): Remove assignment to voffset and
14599 unnecessary vars hshink, expand, hd, full_height, min_height.
14600 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14602 * nsterm.h (nsfont_info): Remove voffset field.
14604 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14606 Implement strike-through and overline on NextStep (Bug#8863).
14608 * nsfont.m (nsfont_open): Use underline position provided by font,
14609 instead of hard-coded value of 2.
14610 (nsfont_draw): Call ns_draw_text_decoration instead.
14612 * nsterm.h: Add declaration for ns_draw_text_decoration.
14614 * nsterm.m (ns_draw_text_decoration): New function for drawing
14615 underline, overline, and strike-through.
14616 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14617 ns_draw_text_decoration. Change treatment of cursor drawing to
14618 accommodate underlining, etc.
14620 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14622 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14625 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14627 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14628 Without this fix, if a signal arrives just after memory fills up,
14629 'malloc' might be invoked reentrantly.
14631 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14632 In other words, assume that every image size is allowed, on non-X
14633 hosts. This assumption is probably wrong, but it lets Emacs compile.
14635 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14637 * regex.c (re_iswctype): Convert return values to boolean.
14639 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14641 * xdisp.c (compute_display_string_pos): Don't use cached display
14642 string position if the buffer had its restriction changed.
14645 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14647 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14649 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14651 Integer signedness and overflow and related fixes. (Bug#9079)
14653 * bidi.c: Integer size and overflow fixes.
14654 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14655 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14656 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14657 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14658 (bidi_find_other_level_edge):
14659 Use ptrdiff_t instead of EMACS_INT where either will do.
14660 This works better on 32-bit hosts configured --with-wide-int.
14661 (bidi_cache_ensure_space): Check for size-calculation overflow.
14662 Use % rather than repeated addition, for better worst-case speed.
14663 Don't set bidi_cache_size until after xrealloc returns, because it
14665 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14666 (bidi_cache_ensure_space): Also check that the bidi cache size
14667 does not exceed that of the largest Lisp string or buffer. See Eli
14668 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14670 * alloc.c (__malloc_size_t): Remove.
14671 All uses replaced by size_t. See Andreas Schwab's note
14672 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14674 * image.c: Improve checking for integer overflow.
14675 (check_image_size): Assume that f is nonnull, since
14676 it is always nonnull in practice. This is one less thing to
14677 worry about when checking for integer overflow later.
14678 (x_check_image_size): New function, which checks for integer
14679 overflow issues inside X.
14680 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14681 This removes the need for a memory_full check.
14682 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14683 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14684 (xbm_read_bitmap_data): Change locals back to 'int', since
14685 their values must fit in 'int'.
14686 (xpm_load_image, png_load, tiff_load):
14687 Invoke x_create_x_image_and_pixmap earlier,
14688 to avoid much needless work if the image is too large.
14689 (tiff_load): Treat overly large images as if
14690 x_create_x_image_and_pixmap failed, not as malloc failures.
14691 (gs_load): Use x_check_image_size.
14693 * gtkutil.c: Omit integer casts.
14694 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14695 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14697 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14699 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14700 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14701 would wrongly return t on a 64-bit host.
14703 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14704 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14705 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14706 and therefore cause GCC to emit a bogus diagnostic in some cases.
14708 * image.c: Integer signedness and overflow and related fixes.
14709 This is not an exhaustive set of fixes, but it's time to
14710 record what I've got.
14711 (lookup_pixel_color, check_image_size): Remove redundant decls.
14712 (check_image_size): Don't assume that arbitrary EMACS_INT values
14713 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14714 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14715 (tiff_load, imagemagick_load_image):
14716 Check for overflow in size calculations.
14717 (x_create_x_image_and_pixmap): Remove unnecessary test for
14718 xmalloc returning NULL; that can't happen.
14719 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14720 (xpm_color_bucket): Use better integer hashing function.
14721 (xpm_cache_color): Don't possibly over-allocate memory.
14722 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14723 (gif_memory_source):
14724 Use ptrdiff_t, not int or size_t, to record sizes.
14725 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14726 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14727 either works, as we prefer signed integers.
14728 (tiff_read_from_memory, tiff_write_from_memory):
14729 Return tsize_t, not size_t, since that's what the TIFF API wants.
14730 (tiff_read_from_memory): Don't fail simply because the read would
14731 go past EOF; instead, return a short read.
14732 (tiff_load): Omit no-longer-needed casts.
14733 (Fimagemagick_types): Don't assume size fits into 'int'.
14735 Improve hashing quality when configured --with-wide-int.
14736 * fns.c (hash_string): New function, taken from sxhash_string.
14737 Do not discard information about ASCII character case; this
14738 discarding is no longer needed.
14739 (sxhash-string): Use it. Change sig to match it. Caller changed.
14740 * lisp.h: Declare it.
14741 * lread.c (hash_string): Remove, since we now use fns.c's version.
14742 The fns.c version returns a wider integer if --with-wide-int is
14743 specified, so this should help the quality of the hashing a bit.
14745 * emacs.c: Integer overflow minor fix.
14746 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14747 Define only if GNU_LINUX.
14748 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14750 * dispnew.c: Integer signedness and overflow fixes.
14751 Remove unnecessary forward decls, that were a maintenance hassle.
14752 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14754 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14755 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14756 (prepare_desired_row, line_draw_cost):
14757 Use int, not unsigned, where either works.
14758 (save_current_matrix, restore_current_matrix):
14759 Use ptrdiff_t, not size_t, where either works.
14760 (init_display): Check for overflow more accurately, and without
14761 relying on undefined behavior.
14763 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14764 Remove, replacing with the new symbols in lisp.h. All uses changed.
14765 * fileio.c (make_temp_name):
14766 * filelock.c (lock_file_1, lock_file):
14767 * xdisp.c (message_dolog):
14768 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14769 Use pMd etc. instead.
14770 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14771 replacing the pWIDE etc. symbols removed from editfns.c.
14773 * keyboard.h (num_input_events): Now uintmax_t.
14774 This is (very slightly) less likely to mess up due to wraparound.
14777 * buffer.c: Integer signedness fixes.
14778 (alloc_buffer_text, enlarge_buffer_text):
14779 Use ptrdiff_t rather than size_t when either will do, as we prefer
14782 * alloc.c: Integer signedness and overflow fixes.
14783 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14784 (__malloc_size_t): Default to size_t, not to int.
14785 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14786 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14787 Prefer ptrdiff_t to size_t when either would do, as we prefer
14789 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14790 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14791 Now const. Initialize with values that are in range even if char
14793 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14794 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14795 These functions do the right thing with sizes > 2**32.
14796 (check_depth): Now ptrdiff_t, not int.
14797 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14798 Adjust to new way of storing sizes. Check for size overflow bugs
14800 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14801 slightly wrong anyway, as it missed one instance of
14802 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14803 (refill_memory_reserve): Omit needless cast to size_t.
14804 (mark_object_loop_halt): Mark as externally visible.
14806 * xselect.c: Integer signedness and overflow fixes.
14807 (Fx_register_dnd_atom, x_handle_dnd_message):
14808 Use ptrdiff_t, not size_t, since we prefer signed.
14809 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14810 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14811 x_dnd_atoms_size and x_dnd_atoms_length.
14813 * doprnt.c: Prefer signed to unsigned when either works.
14815 * doprnt.c (doprnt):
14817 * xdisp.c (vmessage):
14818 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14819 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14820 prefer signed arithmetic to avoid comparison confusion.
14821 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14822 but is a bit tricky.
14824 Assume freestanding C89 headers, string.h, stdlib.h.
14825 * data.c, doprnt.c, floatfns.c, print.c:
14826 Include float.h unconditionally.
14827 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14828 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14829 * regex.c: Likewise for stddef.h, string.h.
14830 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14831 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14832 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14833 (STDC_HEADERS): Remove obsolete defines.
14834 * sysdep.c: Include limits.h unconditionally.
14836 Assume support for memcmp, memcpy, memmove, memset.
14837 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14838 * regex.c (memcmp, memcpy):
14839 Remove; we assume C89 now.
14841 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14842 (__malloc_safe_bcopy): Remove; no longer needed.
14844 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14845 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14846 well either way, and we prefer signed to unsigned.
14848 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14850 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14851 closes the connection while we're reading (bug#9182).
14853 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14855 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14856 are specified (Bug#9168).
14858 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14860 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14861 Found by GCC static checking and --with-wide-int on a 32-bit host.
14863 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14865 * xdisp.c (compute_display_string_pos): Fix logic of caching
14866 previous display string position. Initialize cached_prev_pos to
14867 -1. Fixes slow-down at the beginning of a buffer.
14869 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14871 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14872 for attrs[LFACE_FONTSET_INDEX].
14874 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14876 * xml.c (parse_region): Remove unused local
14877 that was recently introduced.
14879 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14881 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14882 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14884 * xdisp.c (move_it_in_display_line_to): Record the best matching
14885 position for TO_CHARPOS while scanning the line, and restore it on
14886 exit if none of the characters scanned was an exact match.
14887 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14888 when exact match is impossible due to invisible text, and the
14889 lines are truncated.
14891 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14893 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14896 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14898 Fix a significant slow-down of cursor motion with C-n, C-p,
14899 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14900 auto-repeat under bidi redisplay in fontified buffers.
14901 * xdisp.c (compute_stop_pos_backwards): New function.
14902 (next_element_from_buffer): Call compute_stop_pos_backwards to
14903 find a suitable prev_stop when we find ourselves before
14905 (reseat): Don't look for prev_stop, as that could mean a very long
14907 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14908 <cached_disp_overlay_modiff>: Cache for last found display string
14910 (compute_display_string_pos): Return the cached position if asked
14911 about the same buffer in the same area of character positions, and
14912 the buffer wasn't changed since the time the display string
14913 position was cached.
14915 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14917 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14918 is an integer, which is important for empty lines. (Bug#9149)
14920 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14922 * frame.c (Fmodify_frame_parameters): In tty case, update the
14923 default face if necessary (Bug#4238).
14925 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14927 * editfns.c (Fstring_to_char): No need to explain what a character
14928 is in the docstring (Bug#6576).
14930 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14932 * xml.c (parse_region): Make sure we always return a tree.
14934 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14936 * xml.c (parse_region): If a document contains only comments,
14939 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14941 * xml.c (make_dom): Return comments, too.
14943 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14946 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14947 and the surrounding thread.
14948 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14949 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14950 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14952 * s/openbsd.h (BROKEN_SIGIO): Define.
14953 * unexelf.c (unexec) [__OpenBSD__]:
14954 Don't update the .mdebug section of the Alpha COFF symbol table.
14956 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14958 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14961 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14963 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14964 This fixes some race conditions on the permissions of any newly
14967 * alloc.c (valid_pointer_p): Use pipe, not open.
14968 This fixes some permissions issues when debugging.
14970 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14971 If fchown fails to set both uid and gid, try to set just gid,
14972 as that is sometimes allowed. Adjust the file's mode to eliminate
14973 setuid or setgid bits that are inappropriate if fchown fails.
14975 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14977 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14978 to compare Lisp_Objects.
14979 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14980 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14981 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14983 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14985 * lread.c (read_integer): Unread even EOF character.
14986 (read1): Likewise. Properly record start position of symbol.
14988 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14989 symbol character follows.
14991 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14993 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14994 This works around a problem with the previous change to Fcopy_file.
14995 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14996 and without this change, GCC might complain about discarding
14997 fchown's return value.
14999 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15001 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15003 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15005 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15007 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15009 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15010 it's used from the C level.
15012 * process.c: Use the same condition for POLL_FOR_INPUT in both
15013 keyboard.c and process.c (bug#1858).
15015 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15017 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15018 (Fgnutls_boot): Use it.
15020 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15022 * doc.c (Fsubstitute_command_keys): Revert last change.
15024 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15026 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15027 quotes the next character, and doesn't affect other longer
15028 sequences (bug#8935).
15030 * lread.c (syms_of_lread): Clarify that is isn't only
15031 `eval-buffer' and `eval-defun' that's affected by
15032 `lexical-binding' (bug#8460).
15034 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15036 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15037 bidi redisplay when a line includes both an image and is truncated.
15039 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15041 Fix minor problems found by static checking.
15042 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15043 (elsz): Now a signed constant, not a size_t var. We prefer signed
15044 types to unsigned, to avoid integer comparison confusion. Without
15045 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15046 "cannot optimize loop, the loop counter may overflow", a symptom
15048 * indent.c (Fvertical_motion): Mark locals as initialized.
15049 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15051 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15053 * search.c (Fre_search_backward): Mention `case-fold-search' in
15054 all the re_search_* functions (bug#8138).
15056 * keyboard.c (Fopen_dribble_file): Document when the file is
15059 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15061 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15064 Support bidi reordering of display and overlay strings.

15066 (compute_display_string_end): Accept additional argument STRING.
15067 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15068 (reseat_to_string): Initialize bidi_it->string.s and
15069 bidi_it->string.schars.
15070 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15071 NULL (avoids a crash in bidi_paragraph_init).
15072 Initialize itb.string.lstring.
15073 (init_iterator): Call bidi_init_it only of a valid
15074 buffer position was specified. Initialize paragraph_embedding to
15076 (reseat_to_string): Initialize the bidi iterator.
15077 (display_string): If we need to ignore text properties of
15078 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15079 original value of -1 will not work with bidi.)
15080 (compute_display_string_pos): First arg is now struct
15081 `text_pos *'; all callers changed. Support display properties on
15083 (compute_display_string_end): Support display properties on Lisp
15085 (init_iterator, reseat_1, reseat_to_string): Initialize the
15086 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15087 when iterating on a string not from display properties).
15088 (compute_display_string_pos, compute_display_string_end):
15089 Fix calculation of the object to scan. Fixes an error when using
15091 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15092 base_level_stop; instead, set base_level_stop to BEGV.
15093 Fixes crashes in vertical-motion.
15094 (next_element_from_buffer): Improve commentary for when
15095 the iterator is before prev_stop.
15096 (init_iterator): Initialize bidi_p from the default value of
15097 bidi-display-reordering, not from buffer-local value. Use the
15098 buffer-local value only if initializing for buffer iteration.
15099 (handle_invisible_prop): Support invisible properties on strings
15100 that are being bidi-reordered.
15101 (set_iterator_to_next): Support bidi reordering of C strings and
15103 (next_element_from_string): Support bidi reordering of Lisp
15105 (handle_stop_backwards): Support Lisp strings as well.
15106 (display_string): Support display of R2L glyph rows.
15107 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15108 (init_iterator): Don't initialize it->bidi_p for strings
15110 (reseat_to_string): Initialize it->bidi_p for strings here.
15111 (next_element_from_string, next_element_from_c_string)
15112 (next_element_from_buffer): Add xassert's for correspondence
15113 between IT's object being iterated and it->bidi_it.string
15115 (face_before_or_after_it_pos): Support bidi iteration.
15116 (next_element_from_c_string): Handle the case of the first string
15117 character that is not the first one in the visual order.
15118 (get_visually_first_element): New function, refactored from common
15119 parts of next_element_from_buffer, next_element_from_string, and
15120 next_element_from_c_string.
15121 (tool_bar_lines_needed, redisplay_tool_bar)
15122 (display_menu_bar): Force left-to-right direction. Add a FIXME
15123 comment for making that be controlled by a user option.
15124 (push_it, pop_it): Save and restore the state of the
15125 bidi iterator. Save and restore the bidi_p flag.
15126 (pop_it): Iterate out of display property for string iteration as
15128 (iterate_out_of_display_property): Support iteration over strings.
15129 (handle_single_display_spec): Set up it->bidi_it for iteration
15130 over a display string, and call bidi_init_it.
15131 (handle_single_display_spec, next_overlay_string)
15132 (get_overlay_strings_1, push_display_prop): Set up the bidi
15133 iterator for displaying display or overlay strings.
15134 (forward_to_next_line_start): Don't use the shortcut if
15136 (back_to_previous_visible_line_start): If handle_display_prop
15137 pushed the iterator stack, restore the internal state of the bidi
15138 iterator by calling bidi_pop_it same number of times.
15139 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15140 and we are bidi-iterating, don't decrement the iterator position;
15141 instead, set the first_elt flag in the bidi iterator, to produce
15143 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15144 (push_display_prop): xassert that we are iterating a buffer.
15145 (push_it, pop_it): Save and restore paragraph_embedding member.
15146 (handle_single_display_spec, next_overlay_string)
15147 (get_overlay_strings_1, reseat_1, reseat_to_string)
15148 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15149 correctly. Don't assume unibyte strings are not bidi-reordered.
15150 (compute_display_string_pos)
15151 (compute_display_string_end): Fix handling the case of C string.
15152 (push_it, pop_it): Save and restore from_disp_prop_p.
15153 (handle_single_display_spec, push_display_prop): Set the
15154 from_disp_prop_p flag.
15155 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
15156 (pop_it): Call iterate_out_of_display_property only if we are
15157 popping after iteration over a string that came from a display
15158 property. Fix a typo in popping stretch info. Add an assertion
15159 for verifying that the iterator position is in sync with the bidi
15161 (handle_single_display_spec, get_overlay_strings_1)
15162 (push_display_prop): Fix initialization of paragraph direction for
15163 string when that of the parent object is not yet determined.
15164 (reseat_1): Call bidi_init_it to resync the bidi
15165 iterator with IT's position. (Bug#7616)
15166 (find_row_edges): If ROW->start.pos gives position
15167 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
15168 (handle_stop, back_to_previous_visible_line_start, reseat_1):
15169 Reset the from_disp_prop_p flag.
15170 (SAVE_IT, RESTORE_IT): New macros.
15171 (pos_visible_p, face_before_or_after_it_pos)
15172 (back_to_previous_visible_line_start)
15173 (move_it_in_display_line_to, move_it_in_display_line)
15174 (move_it_to, move_it_vertically_backward, move_it_by_lines)
15175 (try_scrolling, redisplay_window, display_line): Use them when
15176 saving a temporary copy of the iterator and restoring it back.
15177 (back_to_previous_visible_line_start, reseat_1)
15178 (init_iterator): Empty the bidi cache "stack".
15179 (move_it_in_display_line_to): If iterator ended up at

15618 in general we prefer signed. When given a limit, use a
15619 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15620 latter isn't right if USE_2_TAGS_FOR_INTS.
15621 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15622 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15624 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15626 * textprop.c (text_property_stickiness):
15627 Obey Vtext_property_default_nonsticky.

15639 * buffer.c (Foverlay_put): Say what the return value is
15642 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15643 is a directory before asking whether to use the file name
15645 (barf_or_query_if_file_exists): Make the "File is a directory"
15646 error be more correct.
15648 * fns.c (Frequire): Remove the mention of the .gz files, since
15649 that's installation-specific, but keep the mention of
15650 `get-load-suffixes'.
15652 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15654 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15659 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
15660 (syms_of_gnutls): Remove duplicate DEFSYM for

15665 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

15767 * eval.c (struct backtrace): Simplify and port the data structure.
15768 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15769 signed bit field, as this assumption is not portable and it makes
15770 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15771 "char debug_on_exit : 1" as this is not portable either; instead,
15772 use the portable "unsigned int debug_on_exit : 1". Remove unused
15773 member evalargs. Remove obsolete comments about cc bombing out.
15775 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

15845 (emacs_fixed_get_preferred_height): Use min_width/height from
15846 frames size_hint to set minimum and natural (Bug#8919).
15847 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15848 and use min_width/height from frames size_hint to set
15849 min_width/height (Bug#8919).

15942 (PRINTPREPARE, printchar, strout):
15943 Don't set size unless allocation succeeds.
15945 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15946 for sizes. Check for string overflow more accurately.

15961 to improve quality of diagnostics for out-of-range radices.
15962 Calculate buffer size correctly for out-of-range radices.
15963 (read1): Check for integer overflow in radices, and in
15964 read-circle numbers.
15965 (read_escape): Avoid int overflow.
15966 (Fload, openp, read_buffer_size, read1)
15967 (substitute_object_recurse, read_vector, read_list, map_obarray):

15990 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15991 The following patches are for when GLYPH_DEBUG && !XASSERT.
15992 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15993 * dispnew.c (flush_stdout):
15994 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15995 Mark as externally visible.
15996 * dispnew.c (check_window_matrix_pointers): Now static.
15997 * dispnew.c (window_to_frame_vpos):
15998 * xfns.c (unwind_create_frame):

16007 (debug_method_add): Use va_list and vsprintf rather than relying
16008 on undefined behavior with wrong number of arguments.
16009 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16010 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16011 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16012 since we're not interested in debugging glyphs with old libraries.
16013 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16014 GCC 4.6.0's static checking.
16016 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

16050 Use ptrdiff_t, not int, for sizes.
16051 (overlays_at, overlays_in): Check for size-calculation overflow.
16053 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16055 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16056 (x_session_initialize): Do not assume string length fits in int.
16058 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16059 This is unlikely, but can occur if DPI is outlandish.
16061 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16062 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16064 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16065 * xrdb.c (magic_file_p, search_magic_path):
16066 Omit last arg SUFFIX; it was always 0. All callers changed.
16067 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16069 * xfont.c (xfont_match): Avoid need for strlen.
16071 * xfns.c: Don't assume strlen fits in int.
16072 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16074 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16075 not unsigned long, as we prefer signed integers. All callers changed.
16076 Detect integer overflow in repeat count.
16077 (message_dolog): Don't assume print length fits in 39 bytes.
16078 (display_mode_element): Don't assume strlen fits in int.
16080 * termcap.c: Don't assume sizes fit in int and never overflow.
16081 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16082 (gobble_line): Check for size-calculation overflow.
16084 * minibuf.c (Fread_buffer):
16085 * lread.c (intern, intern_c_string):
16086 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16087 Don't assume string length fits in int.
16089 * keyboard.c (parse_tool_bar_item):
16090 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16092 * font.c: Don't assume string length fits in int.
16093 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16094 Use ptrdiff_t, not int.
16095 (font_intern_prop): Don't assume string length fits in int.
16096 Don't assume integer property fits in fixnum.
16097 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16099 * filelock.c: Fix some buffer overrun and integer overflow issues.
16100 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16101 Reformulate so as not to need the command string.
16102 Invoke gzip -cd rather than gunzip, as it's more portable.
16103 (lock_info_type, lock_file_1, lock_file):
16104 Don't assume pid_t and time_t fit in unsigned long.
16105 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16106 (current_lock_owner): Prefer signed type for sizes.
16107 Use memcpy, not strncpy, where memcpy is what is really wanted.
16108 Don't assume (via atoi) that time_t and pid_t fit in int.
16109 Check for time_t and/or pid_t out of range, e.g., via a network share.
16110 Don't alloca where an auto var works fine.
16112 * fileio.c: Fix some integer overflow issues.
16113 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16114 Don't assume string length fits in int.
16115 (directory_file_name): Don't assume string length fits in long.
16116 (make_temp_name): Don't assume pid fits in int, or that its print
16117 length is less than 20.
16119 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16121 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16123 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16125 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16126 We prefer signed integers, even for size calculations.
16128 * emacs.c: Don't assume string length fits in 'int'.
16129 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16130 (main): Don't invoke strlen when not needed.
16132 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16133 (XD_DEBUG_MESSAGE): Don't waste a byte.
16135 * callproc.c (getenv_internal_1, getenv_internal)
16136 (Fgetenv_internal):
16137 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16139 * lread.c (invalid_syntax): Omit length argument.
16140 All uses changed. This doesn't fix a bug, but it simplifies the
16141 code away from its former Hollerith-constant appearance, and it's
16142 one less 'int' to worry about when looking at integer-overflow issues.
16143 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16145 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16146 This didn't break anything, but it didn't help either.
16147 It's confusing to put a bogus integer in a place where the actual
16148 value does not matter.
16149 (LIST_END_P): Remove unused macro and its bogus comment.
16150 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16152 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16153 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16155 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16156 We prefer signed types, and the value cannot exceed the EMACS_INT
16157 range anyway (because otherwise the length would not be representable).
16158 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16159 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16160 This avoids a GCC warning when WIDE_EMACS_INT.
16162 * indent.c (sane_tab_width): New function.
16163 (current_column, scan_for_column, Findent_to, position_indentation)
16164 (compute_motion): Use it. This is just for clarity.
16165 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16167 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16169 * lisp.h (lint_assume): New macro.
16170 * composite.c (composition_gstring_put_cache):
16171 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16173 * editfns.c, insdel.c:
16174 Omit unnecessary forward decls, to simplify future changes.
16176 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16178 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16180 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16181 Use much-faster test for byte-length change.
16182 Don't assume string byte-length fits in 'int'.
16183 Check that character arg fits in 'int'.
16184 (mapcar1): Declare byte as byte, for clarity.
16186 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16188 * fns.c (concat): Catch string overflow earlier.
16189 Do not rely on integer wraparound.
16191 * dispextern.h (struct it.overlay_strings_charpos)
16192 (struct it.selective): Now EMACS_INT, not int.
16193 * xdisp.c (forward_to_next_line_start)
16194 (back_to_previous_visible_line_start)
16195 (reseat_at_next_visible_line_start, next_element_from_buffer):
16196 Don't arbitrarily truncate the value of 'selective' to int.
16198 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16200 * composite.c: Don't truncate sizes to 'int'.
16201 (composition_gstring_p, composition_reseat_it)
16202 (composition_adjust_point): Use EMACS_INT, not int.
16203 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16204 not EMACS_UINT, for indexes.
16206 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16208 * buffer.c: Include <verify.h>.
16209 (struct sortvec.priority, struct sortstr.priority):
16210 Now EMACS_INT, not int.
16211 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16212 (struct sortstr.size, record_overlay_string)
16213 (struct sortstrlist.size, struct sortlist.used):
16214 Don't truncate size to int.
16215 (record_overlay_string): Check for size-calculation overflow.
16216 (init_buffer_once): Check at compile-time, not run-time.
16218 2011-06-22 Jim Meyering <meyering@redhat.com>
16220 Don't leak an XBM-image-sized buffer
16221 * image.c (xbm_load): Free the image buffer after using it.
16223 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16226 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16227 that Sun C diagnosed.
16228 * fns.c (secure_hash): Fix pointer signedness issue.
16229 * intervals.c (static_offset_intervals): New function.
16230 (offset_intervals): Use it.
16232 2011-06-21 Leo Liu <sdl.web@gmail.com>
16235 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16238 * fns.c (secure_hash): Rename from crypto_hash_function and change
16239 the first arg to accept symbols.
16240 (Fsecure_hash): New primitive.
16241 (syms_of_fns): New symbols.
16243 2011-06-20 Deniz Dogan <deniz@dogan.se>
16245 * process.c (Fset_process_buffer): Clarify return value in
16248 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16250 * dispnew.c (add_window_display_history): Use BVAR.
16252 * xdisp.c (debug_method_add): Use BVAR.
16253 (check_window_end, dump_glyph_matrix, dump_glyph)
16254 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16256 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16259 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16260 check till after the cache is created in init_frame_faces.
16262 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16264 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16266 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16268 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16269 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16270 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16272 Improve buffer-overflow checking (Bug#8873).
16273 * fileio.c (Finsert_file_contents):
16274 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16275 Remove the old (too-loose) buffer overflow checks.
16276 They weren't needed, since make_gap checks for buffer overflow.
16277 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16278 The old code merely checked for Emacs fixnum overflow, and relied
16279 on undefined (wraparound) behavior. The new code avoids undefined
16280 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16282 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16283 Tune. Don't use wider integers than needed. Don't use alloca.
16284 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16286 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16288 * insdel.c, lisp.h (buffer_overflow): New function.
16289 (insert_from_buffer_1, replace_range, replace_range_2):
16290 * insdel.c (make_gap_larger):
16291 * editfns.c (Finsert_char):
16292 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16294 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16296 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16298 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16300 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16301 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16303 * fileio.c: Don't assume EMACS_INT fits in off_t.
16304 (emacs_lseek): New static function.
16305 (Finsert_file_contents, Fwrite_region): Use it.
16306 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16308 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16310 * fns.c: Don't overflow int when computing a list length.
16311 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16312 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16313 truncation on 64-bit hosts. Check for QUIT every
16314 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16315 faster and is responsive enough.
16316 (Flength): Report an error instead of overflowing an integer.
16317 (Fsafe_length): Return a float if the value is not representable
16318 as a fixnum. This shouldn't happen except in contrived situations.
16319 (Fnthcdr, Fsort): Don't assume list length fits in int.
16320 (Fcopy_sequence): Don't assume vector length fits in int.
16322 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16323 (header_size, word_size): New constants.
16324 (allocate_vectorlike): Don't check size overflow here.
16325 (allocate_vector): Check it here instead, since this is the only
16326 caller of allocate_vectorlike that could cause overflow.
16327 Check that the new vector's length is representable as a fixnum.
16329 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16330 The previous code was bogus. For example, next_almost_prime (32)
16331 returned 39, which is undesirable as it is a multiple of 3; and
16332 next_almost_prime (24) returned 25, which is a multiple of 5 so
16333 why was the code bothering to check for multiples of 7?
16335 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16337 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16339 Variadic C functions now count arguments with ptrdiff_t.
16340 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16341 Back then I didn't know that the Emacs coding style prefers signed int.
16342 Also, in the meantime I found a few more instances where arguments
16343 were being counted with int, which may truncate counts on 64-bit
16344 machines, or EMACS_INT, which may be unnecessarily wide.
16345 * lisp.h (struct Lisp_Subr.function.aMANY)
16346 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16347 Arg counts are now ptrdiff_t, not size_t.
16348 All variadic functions and their callers changed accordingly.
16349 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16350 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16351 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16352 * callint.c (Fcall_interactively): Check arg count for overflow,
16353 to avoid potential buffer overrun. Use signed char, not 'int',
16354 for 'varies' array, so that we needn't bother to check its size
16355 calculation for overflow.
16356 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16357 * eval.c (apply_lambda):
16358 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16359 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16360 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16362 * callint.c (Fcall_interactively): Don't use index var as event count.
16364 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16365 * mem-limits.h (SIZE): Remove; no longer used.
16367 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16369 Remove unnecessary casts.
16370 * xterm.c (x_term_init):
16371 * xfns.c (x_set_border_pixel):
16372 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16373 These aren't needed now that we assume ANSI C.
16375 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16376 It's more likely to cause problems (due to unsigned overflow)
16379 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16381 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16383 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16385 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16387 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16389 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16391 GLYPH_CODE_FACE returns EMACS_INT, not int.
16392 * dispextern.h (merge_faces):
16393 * xfaces.c (merge_faces):
16394 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16395 Don't assume EMACS_INT fits in int.
16397 * character.h (CHAR_VALID_P): Remove unused parameter.
16398 * fontset.c, lisp.h, xdisp.c: All uses changed.
16400 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16402 * fns.c (concat): Minor tuning based on overflow analysis.
16403 This doesn't fix any bugs. Use int to hold character, instead
16404 of constantly refetching from Emacs object. Use XFASTINT, not
16405 XINT, for value known to be a character. Don't bother comparing
16406 a single byte to 0400, as it's always less.
16408 * floatfns.c (Fexpt):
16409 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16411 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16414 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16416 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16417 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16418 incorrectly succeed when S was a string, because 4294967386 was
16419 truncated before it was used.
16421 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16422 Otherwise, an out-of-range integer could cause undefined behavior
16425 * composite.c: Use int, not EMACS_INT, for characters.
16426 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16427 EMACS_INT, for values that are known to be in character range.
16428 This doesn't fix any bugs but is the usual style inside Emacs and
16429 may generate better code on 32-bit machines.
16431 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16432 This is for reasons similar to the recent CHAR_STRING fix.
16433 * charset.c (Fencode_char): Check that character arg is actually
16434 a character. Pass an int to ENCODE_CHAR.
16435 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16436 wider than 'int', as a compile-time check to prevent future regressions
16439 * character.c (char_string): Remove unnecessary casts.
16441 Make sure a 64-bit char is never passed to CHAR_STRING.
16442 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16443 by silently ignoring the top 32 bits, allowing some values
16444 that were far too large to be valid characters.
16445 * character.h: Include <verify.h>.
16446 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16447 arguments are no wider than unsigned, as a compile-time check
16448 to prevent future regressions in this area.
16450 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16451 (Fsubst_char_in_region):
16453 * xdisp.c (decode_mode_spec_coding):
16454 Adjust to CHAR_STRING's new requirement.
16455 * editfns.c (Finsert_char, Fsubst_char_in_region):
16456 * fns.c (concat): Check that character args are actually
16457 characters. Without this test, these functions did the wrong
16458 thing with wildly out-of-range values on 64-bit hosts.
16460 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16461 These casts should not be needed on 32-bit hosts, either.
16462 * keyboard.c (read_char):
16463 * lread.c (Fload): Remove casts to unsigned.
16465 * lisp.h (UNSIGNED_CMP): New macro.
16466 This fixes comparison bugs on 64-bit hosts.
16467 (ASCII_CHAR_P): Use it.
16468 * casefiddle.c (casify_object):
16469 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16470 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16471 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16472 * dispextern.h (FACE_FROM_ID):
16473 * keyboard.c (read_char): Use UNSIGNED_CMP.
16475 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16476 not to EMACS_INT, to avoid GCC warning.
16478 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16480 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16481 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16482 isn't needed on 32-bit machines.
16484 * buffer.c (Fgenerate_new_buffer_name):
16485 Use EMACS_INT for count, not int.
16486 (advance_to_char_boundary): Return EMACS_INT, not int.
16488 * data.c (Qcompiled_function): Now static.
16490 * window.c (window_body_lines): Now static.
16492 * image.c (gif_load): Rename local to avoid shadowing.
16494 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16495 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16496 * alloc.c (make_save_value): Integer argument is now of type
16497 ptrdiff_t, not int.
16498 (mark_object): Use ptrdiff_t, not int.
16499 * lisp.h (pD): New macro.
16500 * print.c (print_object): Use it.
16502 * alloc.c: Use EMACS_INT, not int, to count objects.
16503 (total_conses, total_markers, total_symbols, total_vector_size)

16512 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16513 These were 'int' variables that could overflow on 64-bit hosts;
16514 they were never used, so remove them instead of repairing them.

16531 The definition here is exact; the one in lisp.h was approximate.
16532 (allocate_string_data): Check for string overflow. This catches
16533 some instances we weren't catching before. Also, it catches
16534 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16535 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16536 and ptrdiff_t and EMACS_INT are both 64 bits.

17044 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
17045 Do not assume that spare memory exists; that assumption is valid
17046 only if SYSTEM_MALLOC.
17047 (LARGE_REQUEST): New macro, so that the issue of large requests
17048 is separated from the issue of spare memory.

17109 (bidi_paragraph_init, bidi_resolve_explicit_1)
17110 (bidi_level_of_next_char): Call bidi_fetch_char and

17117 instead of using explicit *_CHAR codes.
17118 (bidi_resolve_explicit, bidi_resolve_weak):

17127 (bidi_level_of_next_char): Don't try to lookup the cache for the
17128 next/previous character if nothing is cached there yet, or if we
17129 were just reseat()'ed to a new position.
17131 * xdisp.c (set_cursor_from_row): Set start and stop points
17132 according to the row's direction when priming the loop that looks
17133 for the glyph on which to display cursor.

17135 (display_prop_intangible_p): Reimplement to call
17136 handle_display_spec instead of single_display_spec_intangible_p.
17137 Accept 3 additional arguments needed by handle_display_spec.
17138 This fixes incorrect cursor motion across display property with complex
17139 values: lists, `(when COND...)' forms, etc.

17141 lists with the argument STRING its top-level element.
17142 (display_prop_string_p): Fix the condition for processing a
17143 property that is a list to be consistent with handle_display_spec.

17145 last portion of handle_display_prop.
17146 (compute_display_string_pos): Accept additional argument
17147 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17148 value of a `display' property is a "replacing spec".
17149 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17150 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17151 the display property, but just return a value indicating whether
17152 the display property will replace the characters it covers.
17153 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17154 frame_window_p members of struct bidi_it.
17155 (compute_display_string_pos, compute_display_string_end):

17161 * keyboard.c (adjust_point_for_property): Adjust the call to
17162 display_prop_intangible_p to its new signature.

17178 All callers changed. (Bug#8762)
17180 * gnutls.c: Use Emacs's memory allocators.
17181 Without this change, the gnutls library would invoke malloc etc.
17182 directly, which causes problems on non-SYNC_INPUT hosts, and which
17183 runs afoul of improving memory_full behavior. (Bug#8761)
17184 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17185 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17186 xfree instead of the default malloc, realloc, free.
17187 (Fgnutls_boot): No need to check for memory allocation failure,
17188 since xmalloc does that for us.
17190 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17191 * category.c (hash_get_category_set):

17210 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17211 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17212 * alloc.c (allocate_vectorlike):
17213 Check for overflow in vector size calculations.
17214 * ccl.c (ccl_driver):
17215 Check for overflow when converting EMACS_INT to int.

17217 need to be updated by these changes.
17218 * fns.c (make_hash_table, maybe_resize_hash_table):
17219 Check for integer overflow with large hash tables.
17220 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17221 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17222 (SXHASH_REDUCE): New macro.
17223 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17224 Use it instead of discarding useful hash info with large hash values.
17225 (sxhash_float): New function.
17226 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17227 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17228 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17229 Rewrite to use FIXNUM_BITS, as this simplifies things.
17230 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17231 Adjust signatures to match updated version of code.
17232 (consing_since_gc): Now EMACS_INT, since a single hash table can
17233 use more than INT_MAX bytes.

17282 Make it possible to run ./temacs.
17284 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17285 syms_of_callproc does the same thing. Remove test for
17286 "initialized", do it in the caller.
17287 * emacs.c (main): Avoid calling set_initial_environment when dumping.

17346 * fns.c (to_uchar): Define.
17347 (crypto_hash_function): Use it to convert some newly-signed
17348 variables to unsigned, to avoid sign-extension bugs. For example,
17349 without this change, (md5 "truc") would evaluate to
17350 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17351 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

17364 that was so large that it became a float. (Bug#8722)
17366 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17367 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17368 Use XFASTINT rather than XUINT when numbers are nonnegative.
17369 (xd_append_arg, Fdbus_method_return_internal):
17370 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17371 arguments, check that Lisp number is nonnegative, rather than
17372 silently wrapping negative numbers around. (Bug#8722)
17373 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17376 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17378 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17380 ccl: Add integer overflow checks.
17381 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17382 (IN_INT_RANGE): New macros.
17383 (ccl_driver): Use them to check for integer overflow when
17384 decoding a CCL program. Many of the new checks are whether XINT (x)
17385 fits in int; it doesn't always, on 64-bit hosts. The new version
17386 doesn't catch all possible integer overflows, but it's an
17387 improvement. (Bug#8719)
17389 * alloc.c (make_event_array): Use XINT, not XUINT.
17390 There's no need for unsigned here.
17392 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17393 This follows up to the 2011-05-06 change that substituted uintptr_t
17394 for EMACS_INT. This case wasn't caught back then.
17396 Rework Fformat to avoid integer overflow issues.
17397 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17398 now (part of C89). Include <verify.h>.
17399 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17400 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17401 (Fformat): Avoid the prepass trying to compute sizes; it was only
17402 approximate and thus did not catch overflow reliably. Instead, walk
17403 through the format just once, formatting and computing sizes as we go,
17404 checking for integer overflow at every step, and allocating a larger
17405 buffer as needed. Keep track separately whether the format is
17406 multibyte. Keep only the most-recently calculated precision, rather
17407 than them all. Record whether each argument has been converted to
17408 string. Use EMACS_INT, not int, for byte and char and arg counts.
17409 Support field widths and precisions larger than INT_MAX. Avoid
17410 sprintf's undefined behavior with conversion specifications such as %#d
17411 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17412 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17413 formatting out-of-range floating point numbers with int
17414 formats. (Bug#8668)
17416 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17418 * data.c: Avoid integer truncation in expressions involving floats.
17419 * data.c: Include <intprops.h>.
17420 (arith_driver): When there's an integer overflow in an expression
17421 involving floating point, convert the integers to floating point
17422 so that the resulting value does not suffer from catastrophic
17423 integer truncation. For example, on a 64-bit host (* 4
17424 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17425 Do not rely on undefined behavior after integer overflow.
17427 merge count_size_as_multibyte, parse_str_to_multibyte
17428 * character.c, character.h (count_size_as_multibyte):
17429 Rename from parse_str_to_multibyte; all uses changed.
17430 Check for integer overflow.
17431 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17432 since it's now a duplicate of the other. This is more of
17433 a character than a buffer op, so better that it's in character.c.
17434 * fns.c, print.c: Adjust to above changes.
17436 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17438 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17440 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17442 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17443 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17444 (x_clipboard_manager_save): Now static.
17445 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17447 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17448 (crypto_hash_function): Now static.
17449 Fix pointer signedness problems. Avoid unnecessary initializations.
17451 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17453 * termhooks.h (Vselection_alist): Make it terminal-local.
17455 * terminal.c (create_terminal): Initialize it.
17457 * xselect.c: Support for clipboard managers.
17458 (Vselection_alist): Move to termhooks.h as terminal-local var.
17459 (LOCAL_SELECTION): New macro.
17460 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17461 (symbol_to_x_atom): Remove gratuitous arg.
17462 (x_handle_selection_request, lisp_data_to_selection_data)
17463 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17464 (x_own_selection, x_get_local_selection, x_convert_selection):
17465 New arg, specifying work frame. Use terminal-local Vselection_alist.
17466 (some_frame_on_display): Delete unused function.
17467 (Fx_own_selection_internal, Fx_get_selection_internal)
17468 (Fx_disown_selection_internal, Fx_selection_owner_p)
17469 (Fx_selection_exists_p): New optional frame arg.
17470 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17471 (x_handle_selection_clear): Don't treat other terminals with the
17472 same keyboard specially. Use the terminal-local Vselection_alist.
17473 (x_clear_frame_selections): Use Frun_hook_with_args.
17475 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17477 * xterm.h: Add support for those atoms.
17479 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17481 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17482 (converted_selections, conversion_fail_tag): New global variables.
17483 (x_selection_request_lisp_error): Free the above.
17484 (x_get_local_selection): Remove unnecessary code.
17485 (x_reply_selection_request): Args changed; handle arbitrary array
17486 of converted selections stored in converted_selections.
17487 Separate the XChangeProperty and SelectionNotify steps.
17488 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17489 (x_convert_selection): New function.
17490 (x_handle_selection_event): Simplify.
17491 (x_get_foreign_selection): Don't ignore incoming requests while
17492 waiting for an answer; this will fail when we implement
17493 SAVE_TARGETS, and seems unnecessary anyway.
17494 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17495 (Vx_sent_selection_functions): Doc fix.
17497 2011-05-26 Leo Liu <sdl.web@gmail.com>
17499 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17501 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17503 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17505 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17506 for fringe update if it has periodic bitmap.
17507 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17508 and fringe_bitmap_periodic_p.
17510 * fringe.c (get_fringe_bitmap_data): New function.
17511 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17512 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17513 row. Mark glyph row for fringe update if periodicity changed.
17515 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17516 for fringe update unless it has periodic bitmap.
17518 2011-05-25 Kenichi Handa <handa@m17n.org>
17520 * xdisp.c (get_next_display_element): Set correct it->face_id for
17521 a static composition.
17523 2011-05-24 Leo Liu <sdl.web@gmail.com>
17526 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17528 * fns.c (crypto_hash_function, Fsha1): New function.
17529 (Fmd5): Use crypto_hash_function.
17530 (syms_of_fns): Add Ssha1.
17532 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17534 * gnutls.c: Remove unused macros.
17535 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17536 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17537 Remove macros that are defined and never used.
17538 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17540 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17542 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17543 (Fx_get_selection_internal): Minor cleanup.
17544 (Fx_own_selection_internal): Rename arguments for consistency with
17547 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17549 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17551 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17553 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17555 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17557 * dispnew.c (scrolling_window): Don't exclude the case that the
17558 last enabled row in the desired matrix touches the bottom boundary.
17560 2011-05-21 Glenn Morris <rgm@gnu.org>
17562 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17563 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17564 and add some more files.
17566 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17568 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17569 report_file_error introduced by the change from 2011-05-07.
17571 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17573 * systime.h (Time): Define only if emacs is defined.
17574 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17575 where the include path doesn't have X11/X.h by default. See
17576 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17578 2011-05-20 Kenichi Handa <handa@m17n.org>
17580 * composite.c (find_automatic_composition): Fix previous change.
17582 2011-05-20 Glenn Morris <rgm@gnu.org>
17584 * lisp.mk: New file, split from Makefile.in.
17585 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17586 (shortlisp): Remove.
17587 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17589 2011-05-19 Glenn Morris <rgm@gnu.org>
17591 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17592 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17593 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17594 (lisp): Set the order to that of loadup.el.
17595 (shortlisp): Make it a copy of $lisp.
17596 (SOME_MACHINE_LISP): Remove.
17597 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17598 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17600 2011-05-18 Kenichi Handa <handa@m17n.org>
17602 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17603 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17604 (find_automatic_composition): Mostly rewrite for efficiency.
17606 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17608 * makefile.w32-in: Update dependencies.
17610 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17612 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17613 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17615 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17617 Fix some integer overflow issues, such as string length overflow.
17619 * insdel.c (count_size_as_multibyte): Check for string overflow.
17621 * character.c (lisp_string_width): Check for string overflow.
17622 Use EMACS_INT, not int, for string indexes and lengths; in
17623 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17624 the resulting string length overflows an EMACS_INT; instead,
17625 report a string overflow if no precision given. When checking for
17626 precision exhaustion, use a check that cannot possibly have
17627 integer overflow. (Bug#8675)
17628 * character.h (lisp_string_width): Adjust to new signature.
17630 * alloc.c (string_overflow): New function.
17631 (Fmake_string): Use it. This doesn't change behavior, but saves
17632 a few bytes and will simplify future changes.
17633 * character.c (string_escape_byte8): Likewise.
17634 * lisp.h (string_overflow): New decl.
17636 Fixups, following up to the user-interface timestamp change.
17637 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17638 for UI timestamps, instead of unsigned long.
17639 * msdos.c (mouse_get_pos): Likewise.
17640 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17641 * w32gui.h (Time): Define by including "systime.h" rather than by
17642 declaring it ourselves. (Bug#8664)
17644 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17645 * image.c (clear_image_cache): Likewise.
17647 * term.c (term_mouse_position): Don't assume time_t wraparound.
17649 Be more systematic about user-interface timestamps.
17650 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17651 and sometimes 'EMACS_UINT', to represent these timestamps.
17652 This change causes it to use 'Time' uniformly, as that's what X uses.
17653 This makes the code easier to follow, and makes it easier to catch
17654 integer overflow bugs such as Bug#8664.
17655 * frame.c (Fmouse_position, Fmouse_pixel_position):
17656 Use Time, not unsigned long, for user-interface timestamps.
17657 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17658 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17659 * keyboard.h (last_event_timestamp): Likewise.
17660 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17661 * menu.h (xmenu_show): Likewise.
17662 * term.c (term_mouse_position): Likewise.
17663 * termhooks.h (struct input_event.timestamp): Likewise.
17664 (struct terminal.mouse_position_hook): Likewise.
17665 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17666 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17667 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17668 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17669 what it was before.
17670 * menu.h, termhooks.h: Include "systime.h", for Time.
17672 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17673 Don't assume that the difference between two unsigned long values
17674 can fit into an integer. At this point, we know button_down_time
17675 <= event->timestamp, so the difference must be nonnegative, so
17676 there's no need to cast the result if double-click-time is
17677 nonnegative, as it should be; check that it's nonnegative, just in
17678 case. This bug is triggered when events are more than 2**31 ms
17679 apart (about 25 days). (Bug#8664)
17681 * xselect.c (last_event_timestamp): Remove duplicate decl.
17682 (x_own_selection): Remove needless cast to unsigned long.
17684 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17685 that always fit in int. Use a sentinel instead of a counter, to
17686 avoid a temp and to allay GCC's concerns about possible int overflow.
17687 * frame.h (struct frame): Use int for menu_bar_items_used
17688 instead of EMACS_INT, since it always fits in int.
17690 * menu.c (grow_menu_items): Check for int overflow.
17692 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17694 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17695 Before, the code was not consistent. These values cannot exceed
17696 2**31 - 1 so there's no need to make them unsigned.
17697 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17698 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17699 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17701 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17703 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17704 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17705 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17706 presumably because the widths might not match.
17708 * window.c (size_window): Avoid needless test at loop start.
17710 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17712 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17714 2011-05-12 Drew Adams <drew.adams@oracle.com>
17716 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17718 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17720 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17721 `width' to `bar_area_x' and `bar_area_width', respectively.
17722 (x_scroll_run): Take account of fringe background extension.
17724 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17725 Rename local vars `left' and `width' to `bar_area_x' and
17726 `bar_area_width', respectively.
17727 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17728 background extension.
17730 2011-05-10 Jim Meyering <meyering@redhat.com>
17732 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17734 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17736 * image.c (Finit_image_library): Return t for built-in image types,
17737 like pbm and xbm. (Bug#8640)
17739 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17741 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17743 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17745 * w32console.c (Fset_screen_color): Doc fix.
17746 (Fget_screen_color): New function.
17747 (syms_of_ntterm): Defsubr it.
17749 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17750 unlink the temporary file if Fcall_process didn't create it in the
17752 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17753 child process will be redirected to a file specified with `:file'.
17754 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17755 cue to call_process_cleanup not to close that handle.
17757 2011-05-07 Ben Key <bkey76@gmail.com>
17759 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17760 one of two shell specific rules, either bootstrap-temacs-CMD or
17761 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17762 to the previous implementation of the bootstrap-temacs rule.
17763 The bootstrap-temacs-CMD rule is similar to the previous
17764 implementation of the bootstrap-temacs rule except that it
17765 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17768 These changes, along with some changes to nt/configure.bat,
17769 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17770 earlier fix to add support for --cflags and --ldflags options
17771 that include quotes so that it works whether make uses cmd or
17774 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17776 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17777 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17779 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17780 a string. Handle both cases.
17781 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17782 (Fdbus_register_method): Use Qinvalid_function.
17784 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17786 * makefile.w32-in: Update dependencies.
17787 (LISP_H): Add inttypes.h and stdin.h.
17788 (PROCESS_H): Add unistd.h.
17790 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17792 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17793 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17795 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17797 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17799 * term.c (vfatal): Remove stray call to va_end.
17800 It's not needed and the C Standard doesn't allow it here anyway.
17802 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17803 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17805 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17808 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17810 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17812 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17814 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17816 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17818 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17819 * charset.c (Fdefine_charset_internal): Don't initialize
17820 charset.code_space[15]. The value was garbage, on hosts with
17821 32-bit int (Bug#8600).
17823 * lread.c (read_integer): Be more consistent with string-to-number.
17824 Use string_to_number to do the actual conversion; this avoids
17825 rounding errors and fixes some other screwups. Without this fix,
17826 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17827 (digit_to_number): Move earlier, for benefit of read_integer.
17828 Return -1 if the digit is out of range for the base, -2 if it is
17829 not a digit in any supported base. (Bug#8602)
17831 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17833 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17834 to match comment at start of function. This also removes a
17835 GCC warning about overflow in a 32+64-bit port.
17837 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17839 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17840 Reported by Stefan Monnier in
17841 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17842 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17843 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17845 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17846 (EMACS_UINTPTR): Likewise, with uintptr_t.
17848 * lisp.h: Prefer 64-bit EMACS_INT if available.
17849 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17850 on 32-bit hosts that have 64-bit int, so that they can access
17852 However, temporarily disable this change unless the temporary
17853 symbol WIDE_EMACS_INT is defined.
17855 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17857 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17858 This removes an assumption that EMACS_INT and long are the same
17859 width as pointers. The assumption is true for Emacs porting targets
17860 now, but we want to make other targets possible.
17861 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17862 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17863 In the rest of the code, change types of integers that hold casted
17864 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17865 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17866 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17867 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17868 No need to cast type when ORing.
17869 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17870 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17871 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17872 assume EMACS_INT is the same width as char *.
17873 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17874 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17875 Remove no-longer-needed casts.
17876 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17877 (xg_tool_bar_help_callback, xg_make_tool_item):
17878 Use EMACS_INTPTR to hold an integer
17879 that will be cast to void *; this can avoid a GCC warning
17880 if EMACS_INT is not the same width as void *.
17881 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17882 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17883 (current_message_1, set_message_1):
17884 Use a local to convert to proper width without a cast.
17885 * xmenu.c (dialog_selection_callback): Likewise.
17887 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17888 Also, don't assume VALBITS / RAND_BITS is less than 5,
17889 and don't rely on undefined behavior when shifting a 1 left into
17891 * lisp.h (get_random): Change signature to match.
17893 * lread.c (hash_string): Use size_t, not int, for hash computation.
17894 Normally we prefer signed values; but hashing is special, because
17895 it's better to use unsigned division on hash table sizes so that
17896 the remainder is nonnegative. Also, size_t is the natural width
17897 for hashing into memory. The previous code used 'int', which doesn't
17898 retain enough info to hash well into very large tables.
17899 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17901 * dbusbind.c: Don't possibly lose pointer info when converting.
17902 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17903 Use XPNTR rather than XHASH, so that the high-order bits of
17904 the pointer aren't lost when converting through void *.
17906 * eval.c (Fautoload): Don't double-shift a pointer.
17908 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17910 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17912 * gnutls.c (DEF_GNUTLS_FN):
17913 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17915 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17917 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17920 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17922 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17923 New version that can reserve upto 2GB of heap space.
17925 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17927 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17929 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17931 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17932 `gnutls_certificate_set_x509_key_file'.
17934 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17936 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17937 Update dependencies.
17939 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17941 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17942 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17943 Remove unused parameter `fildes'.
17944 * process.c (read_process_output, send_process): Don't pass it.
17946 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17948 Fix previous change: the library cache is defined in w32.c.
17949 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17950 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17952 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17954 Implement dynamic loading of GnuTLS on Windows.
17956 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17957 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17958 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17961 * gnutls.c (Qgnutls_dll): Define.
17962 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17963 (gnutls_*): Declare function pointers.
17964 (init_gnutls_functions): New function to initialize function pointers.

17967 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17968 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17969 (emacs_gnutls_write, emacs_gnutls_read)
17970 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17971 (Fgnutls_available_p): New function.
17972 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

17980 (w32_delayed_load): Move to w32.c.
17982 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17984 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17985 (w32_delayed_load): Move from image.c. When loading a library, record
17986 its filename in the :loaded-from property of the library id.
17987 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17988 Initialize and staticpro them.
17989 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17991 * process.c: Include lisp.h before w32.h, not after.
17992 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17993 instead of gnutls_record_check_pending.
17995 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17997 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17999 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18000 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18003 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18005 * xterm.c (x_set_frame_alpha): Do not set property on anything
18006 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18008 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18010 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18012 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18014 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

18028 * sysdep.c (wait_for_termination_1): Make static.
18029 (wait_for_termination, interruptible_wait_for_termination):
18030 Move after wait_for_termination_1.
18032 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18034 * sysdep.c (interruptible_wait_for_termination): New function
18035 which is like wait_for_termination, but allows keyboard
18038 * callproc.c (Fcall_process): Add (:file "file") as an option for
18040 (Fcall_process_region): Ditto.
18042 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18044 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18045 rather than `XVECTOR (FOO)->size'.
18047 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18048 inttypes.h, as a gnulib replacement is used if it not available in
18051 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18053 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18054 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18055 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18057 * coding.c (coding_alloc_by_realloc): Error out if destination
18058 will grow beyond MOST_POSITIVE_FIXNUM.
18059 (decode_coding_emacs_mule): Abort if there isn't enough place in
18060 charbuf for the composition carryover bytes. Reserve an extra
18061 space for up to 2 characters produced in a loop.
18062 (decode_coding_iso_2022): Abort if there isn't enough place in
18063 charbuf for the composition carryover bytes.
18065 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18067 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18068 aborting when %lld or %lll format is passed.
18069 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18070 %llo or %llx format is passed. (Bug#8545)
18072 * window.c (window_scroll_line_based): Use a marker instead of
18073 simple variables to record original value of point. (Bug#7952)
18075 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18076 produced by %s or %c overflows available buffer space. (Bug#8545)
18078 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18080 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18081 (SIZE_MAX): Move defn after all includes, as they might #define it.
18083 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

18087 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18089 * keyboard.c (Qdelayed_warnings_hook): Define.
18090 (command_loop_1): Run `delayed-warnings-hook'
18091 if Vdelayed_warnings_list is non-nil.
18092 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18093 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18095 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18097 * doprnt.c (doprnt): Don't return value smaller than the buffer
18098 size if the message was truncated. (Bug#8545).
18100 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18102 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18103 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18105 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18107 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18109 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18111 * makefile.w32-in: Update dependencies.
18113 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18115 Improve `doprnt' and its usage. (Bug#8545)
18116 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18117 `format_end'. Remove support for %l as a conversion specifier.
18118 Don't use xrealloc. Improve diagnostics when the %l size modifier
18119 is used. Update the commentary.
18121 * eval.c (verror): Simplify calculation of size_t.
18123 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18126 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18128 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18131 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18133 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18134 This makes this file independent of the recent pseudovector change.
18136 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18138 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18140 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18141 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18142 Remove unused local.
18143 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18145 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18146 GCC 4.6.0 optimizes based on type-based alias analysis.
18147 For example, if b is of type struct buffer * and v of type struct
18148 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18149 != &v->size, and therefore "v->size = 1; b->size = 2; return
18150 v->size;" must therefore return 1. This assumption is incorrect
18151 for Emacs, since it type-puns struct Lisp_Vector * with many other
18152 types. To fix this problem, this patch adds a new type struct
18153 vectorlike_header that documents the constraints on layout of vectors
18154 and pseudovectors, and helps optimizing compilers not get fooled
18155 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18156 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18157 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18159 (XSETPVECTYPE): Rewrite in terms of new macro.
18160 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18161 This is a bit clearer, and further avoids the possibility of
18162 undesirable aliasing.
18163 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18164 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18165 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18166 since Lisp_Subr is a special case (no "next" field).
18167 (ASIZE): Now uses header.size rather than size.
18168 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18169 to avoid the hassle of writing XVECTOR (foo)->header.size.
18170 (struct vectorlike_header): New type.
18171 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18172 object, to help avoid aliasing.
18173 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18174 (SUBRP): Likewise, since Lisp_Subr is a special case.
18175 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18176 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18177 (struct Lisp_Hash_Table): Combine first two members into a single
18178 struct vectorlike_header member. All uses of "size" and "next" members
18179 changed to be "header.size" and "header.next".
18180 * buffer.h (struct buffer): Likewise.
18181 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18182 * frame.h (struct frame): Likewise.
18183 * process.h (struct Lisp_Process): Likewise.
18184 * termhooks.h (struct terminal): Likewise.
18185 * window.c (struct save_window_data, struct saved_window): Likewise.
18186 * window.h (struct window): Likewise.
18187 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18188 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18189 * buffer.c (init_buffer_once): Likewise.
18190 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18192 * process.c (Fformat_network_address): Use local var for size,
18195 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18197 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18198 * data.c (atof): Remove decl; no longer used or needed.
18199 (digit_to_number): Move to lread.c.
18200 (Fstring_to_number): Use new string_to_number function, to be
18201 consistent with how the Lisp reader treats infinities and NaNs.
18202 Do not assume that floating-point numbers represent EMACS_INT
18203 without losing information; this is not true on most 64-bit hosts.
18204 Avoid double-rounding errors, by insisting on integers when
18205 parsing non-base-10 numbers, as the documentation specifies.
18206 * lisp.h (string_to_number): New decl, replacing ...
18207 (isfloat_string): Remove.
18208 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18209 (read1): Do not accept +. and -. as integers; this
18210 appears to have been a coding error. Similarly, do not accept
18211 strings like +-1e0 as floating point numbers. Do not report
18212 overflow for integer overflows unless the base is not 10 which
18213 means we have no simple and reliable way to continue.
18214 Break out the floating-point parsing into a new
18215 function string_to_number, so that Fstring_to_number parses
18216 floating point numbers consistently with the Lisp reader.
18217 (digit_to_number): Move here from data.c. Make it static inline.
18218 (E_CHAR, EXP_INT): Remove, replacing with ...
18219 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18220 (string_to_number): New function, replacing isfloat_string.
18221 This function checks for valid syntax and produces the resulting
18222 Lisp float number too. Rework it so that string-to-number
18223 no longer mishandles examples like "1.0e+". Use strtoumax,
18224 so that overflow for non-base-10 numbers is reported only when
18225 there's no portable and simple way to convert to floating point.
18227 * textprop.c (set_text_properties_1): Rewrite for clarity,
18228 and to avoid GCC warning about integer overflow.
18230 * intervals.h (struct interval): Use EMACS_INT for members
18231 where EMACS_UINT might cause problems. See
18232 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18233 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18234 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18236 (offset_intervals): Tell GCC not to worry about length overflow
18237 when negating a negative length.
18239 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18240 (overrun_check_free): Likewise.
18242 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18243 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18246 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18247 (gnutls_make_error): Rename local to avoid shadowing.

18250 Comment out unused local. Fix pointer signedness problems.
18252 * lread.c (openp): Don't stuff size_t into an 'int'.
18253 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18254 about possible signed overflow.
18256 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18257 (GDK_KEY_g): Don't define if already defined.
18258 (xg_prepare_tooltip): Avoid pointer signedness problem.
18259 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18261 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18262 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18264 * xfns.c (Fx_window_property): Simplify a bit,
18265 to make a bit faster and to avoid GCC 4.6.0 warning.
18266 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18268 * fns.c (internal_equal): Don't assume size_t fits in int.
18270 * alloc.c (compact_small_strings): Tighten assertion a little.
18272 Replace pEd with more-general pI, and fix some printf arg casts.
18273 * lisp.h (pI): New macro, generalizing old pEd macro to other
18274 conversion specifiers. For example, use "...%"pI"d..." rather
18275 than "...%"pEd"...".
18276 (pEd): Remove. All uses replaced with similar uses of pI.
18277 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18278 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18279 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18280 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18281 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18282 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18283 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18285 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18286 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18287 * print.c (safe_debug_print, print_object): Likewise.
18288 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18290 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18291 avoiding the 0 flag, which is not portable.
18292 * process.c (Fmake_network_process): Use pI to avoid cast.
18293 * region-cache.c (pp_cache): Likewise.
18294 * xdisp.c (decode_mode_spec): Likewise.
18295 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18296 behavior on 64-bit hosts with printf arg.
18297 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18298 (x_stop_queuing_selection_requests): Likewise.
18299 (x_get_window_property): Don't truncate byte count to an 'int'
18302 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18303 here, since it parses constructs like leading '-' and spaces,
18304 which are not wanted; and it overflows with large numbers.
18305 Instead, simply match F[0-9]+, which is what is wanted anyway.
18307 * alloc.c: Remove unportable assumptions about struct layout.
18308 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18309 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18310 (allocate_vectorlike, make_pure_vector): Use the new macros,
18311 plus offsetof, to remove unportable assumptions about struct layout.
18312 These assumptions hold on all porting targets that I know of, but
18313 they are not guaranteed, they're easy to remove, and removing them
18314 makes further changes easier.
18316 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18317 This doesn't fix a bug but makes the code clearer.
18318 (string_overrun_cookie): Now const. Use initializers that
18319 don't formally overflow signed char, to avoid warnings.
18320 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18321 can cause Emacs to crash when string overrun checking is enabled.
18322 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18323 multiple of sizeof (EMACS_INT); it need not be, if
18324 alignof(EMACS_INT) < sizeof (EMACS_INT).
18325 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18327 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18354 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18356 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18357 "cast to pointer from integer of different size".
18359 Improve doprnt and its use in verror. (Bug#8545)
18360 * doprnt.c (doprnt): Document the set of format control sequences
18361 supported by the function. Use SAFE_ALLOCA instead of always
18364 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18365 is one byte too soon. Don't use xrealloc; instead xfree and
18368 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18370 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

18374 gnutls_global_initialized. Added internals for the
18375 :verify-hostname-error, :verify-error, and :verify-flags
18376 parameters of `gnutls-boot' and documented those parameters in the
18377 docstring. Start callback support.
18378 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18379 unless a fatal error occurred. Call gnutls_alert_send_appropriate

18457 conversions. Support %l conversion. Don't assume an EMACS_INT
18458 argument for integer conversions and for %c.

18477 * callint.c (Fcall_interactively): When displaying error message
18478 about invalid control letter, pass the character's codepoint, not

18483 codepoint of an invalid character, to avoid displaying a bogus
18486 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18487 `error', not SYMBOL_NAME itself.

18492 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18493 to `error' in error message about FINAL_CHAR argument. Make sure
18494 FINAL_CHAR is a character, and use %c when it is passed as
18495 argument to `error'.
18497 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18499 * s/ms-w32.h (localtime): Redirect to sys_localtime.
18501 * w32.c: Include <time.h>.

18562 by pacifying GCC about it. Maybe it's time to retire it?
18563 * xfaces.c (USG, __TIMEVAL__): Likewise.
18565 * dispextern.h (struct redisplay_interface): Rename param
18566 to avoid shadowing.
18567 * termhooks.h (struct terminal): Likewise.
18568 * xterm.c (xembed_send_message): Likewise.
18570 * insdel.c (make_gap_smaller): Define only if
18571 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.

18614 compatible char. Avoid the old compiler warnings about
18615 out-of-range initializers by using, for example, '\xab' rather
18618 * xgselect.c (xgselect_initialize): Check vs interface
18619 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

18669 (group_in_compile_stack, re_search, re_search_2, regex_compile)
18670 (re_compile_pattern, re_exec): Declare arguments and local
18671 variables `size_t' and `ssize_t' and return values `regoff_t', as

18679 specify buffer/string position and length are now ssize_t and
18680 size_t. Return type is regoff_t.
18682 2011-04-16 Ben Key <bkey76@gmail.com>
18684 * nsfont.m: Fixed bugs in ns_get_family and
18685 ns_descriptor_to_entity that were caused by using free to
18686 deallocate memory blocks that were allocated by xmalloc (via
18687 xstrdup). This caused Emacs to crash when compiled with
18688 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18689 --enable-checking=xmallocoverrun). xfree is now used to
18690 deallocate these memory blocks.

19117 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19118 Mark functions with DEFUE instead of DEFUN,
19119 if they are used in other modules.
19120 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19121 decls for now-static functions.
19122 * buffer.h (Fdelete_overlay): Remove decl.
19123 * callproc.c (Fgetenv_internal): Mark as internal.

19158 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19160 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19161 when at ZV. (Bug#8487)
19163 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19165 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19167 * keyboard.c (parse_tool_bar_item): Likewise.
19168 * sound.c (sound_cleanup, alsa_close): Likewise.
19169 * termcap.c (tgetent): Likewise.
19170 * xfns.c (x_default_font_parameter): Likewise.
19171 * xsettings.c (read_and_apply_settings): Likewise.
19173 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19174 (overrun_check_free): Protoize.
19176 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19178 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19179 since callers should never pass a negative size.
19180 Change the signature to match that of plain 'read' and 'write'; see
19181 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19182 * lisp.h: Update prototypes of emacs_write and emacs_read.
19184 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19186 * xdisp.c (redisplay_window): Don't try to determine the character
19187 position of the scroll margin if the window start point w->startp
19188 is outside the buffer's accessible region. (Bug#8468)
19190 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19192 Fix write-region and its subroutines for buffers > 2GB.
19193 * fileio.c (a_write, e_write): Modify declaration of arguments and
19194 local variables to support buffers larger than 2GB.
19195 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19197 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19198 argument, local variables, and return value.
19200 * lisp.h: Update prototypes of emacs_write and emacs_read.
19202 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19204 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19206 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19208 Fix more problems found by GCC 4.6.0's static checks.
19210 * xdisp.c (vmessage): Use a better test for character truncation.
19212 * charset.c (load_charset_map): <, not <=, for optimization,
19213 and to avoid potential problems with integer overflow.
19214 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19215 * casetab.c (set_identity, shuffle): Likewise.
19216 * editfns.c (Fformat): Likewise.
19217 * syntax.c (skip_chars): Likewise.
19219 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19220 This also lets GCC 4.6.0 generate slightly better loop code.
19222 * callint.c (Fcall_interactively): <, not <=, for optimization.
19223 (Fcall_interactively): Count the number of arguments produced,
19224 not the number of arguments given. This is simpler and lets GCC
19225 4.6.0 generate slightly better code.
19227 * ftfont.c: Distingish more carefully between FcChar8 and char.
19228 The previous code passed unsigned char * to a functions like
19229 strlen and xstrcasecmp that expect char *, which does not
19230 conform to the C standard.
19231 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19232 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19233 char * when the C standard requires it.
19235 * keyboard.c (read_char): Remove unused var.
19237 * eval.c: Port to Windows vsnprintf (Bug#8435).
19238 Include <limits.h>.
19239 (SIZE_MAX): Define if the headers do not.
19240 (verror): Do not give up if vsnprintf returns a negative count.
19241 Instead, grow the buffer. This ports to Windows vsnprintf, which
19242 does not conform to C99. Problem reported by Eli Zaretskii.
19243 Also, simplify the allocation scheme, by avoiding the need for
19244 calling realloc, and removing the ALLOCATED variable.
19246 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19248 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19249 But keep the doprint source code for now, as we might revamp it
19250 and use it again (Bug#8435).
19251 * lisp.h (doprnt): Remove.
19252 * Makefile.in (base_obj): Remove doprnt.o.
19253 * deps.mk (doprnt.o): Remove.
19255 error: Print 32- and 64-bit integers portably (Bug#8435).
19256 Without this change, on typical 64-bit hosts error ("...%d...", N)
19257 was used to print both 32- and 64-bit integers N, which relied on
19258 undefined behavior.
19259 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19260 * lisp.h (error, verror): Mark as printf-like functions.
19261 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19262 Report overflow in size calculations when allocating printf buffer.
19263 Do not truncate output string at its first null byte.
19264 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19265 Truncate the output at a character boundary, since vsnprintf does not
19267 * charset.c (check_iso_charset_parameter): Convert internal
19268 character to string before calling 'error', since %c now has the
19270 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19271 overflow when computing char to be passed to 'error'. Do not
19272 pass Lisp_Object to 'error'; pass the integer instead.
19273 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19274 formatted with plain %d.
19276 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19278 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19280 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19282 * xterm.c (x_catch_errors): Remove duplicate declaration.
19284 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19286 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19288 2011-04-10 Jim Meyering <meyering@redhat.com>
19290 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19291 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19292 return ssize_t not "int", and use size_t as the buffer length.
19293 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19294 * gnutls.h: Update declarations.
19295 * process.c (read_process_output): Use ssize_t, to match.
19296 (send_process): Likewise.
19298 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19300 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19302 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19304 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19305 Use unsigned char, to match FcChar8 type definition.
19307 * xterm.c (handle_one_xevent):
19308 * xmenu.c (create_and_show_popup_menu):
19309 * xselect.c (x_decline_selection_request)
19310 (x_reply_selection_request): Avoid type-punned deref of X events.
19312 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19314 Fix some uses of `int' instead of EMACS_INT.
19315 * search.c (string_match_1, fast_string_match)
19316 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19317 (scan_buffer, find_next_newline_no_quit)
19318 (find_before_next_newline, search_command, Freplace_match)
19319 (Fmatch_data): Make some `int' variables be EMACS_INT.
19321 * xdisp.c (display_count_lines): 3rd argument and return value now
19322 EMACS_INT. All callers changed.
19323 (pint2hrstr): Last argument is now EMACS_INT.
19325 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19326 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19327 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19338 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19339 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19341 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19342 (encode_invocation_designation): Last argument P_NCHARS is now
19344 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19345 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19347 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19350 * ccl.c (Fccl_execute_on_string): Declare some variables
19353 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19355 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19357 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19359 * process.c (Fformat_network_address): Doc fix.
19361 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19363 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19365 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19367 * keyboard.c (read_char): Call Lisp function help-form-show,
19368 instead of using internal_with_output_to_temp_buffer.
19369 (Qhelp_form_show): New var.
19370 (syms_of_keyboard): Use DEFSYM macro.
19372 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19374 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19376 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19378 * process.c (Flist_processes): Remove to Lisp.
19379 (list_processes_1): Delete.
19381 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19383 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19385 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19387 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19389 Fix more problems found by GCC 4.6.0's static checks.
19391 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19393 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19395 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19397 * xdisp.c (vmessage): Mark as a printf-like function.
19399 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19401 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19403 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19404 printf-like functions.
19405 (tiff_load): Add casts to remove these marks before passing them
19406 to system-supplied API.
19408 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19410 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19411 This avoids several warnings with gcc -Wstrict-overflow.
19412 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19413 directly, rather than having caller test rule sign. This avoids
19414 some unnecessary tests.
19415 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19416 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19417 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19419 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19420 (xfont_open): Avoid unnecessary tests.
19422 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19424 * composite.h, composite.c (composition_gstring_put_cache):
19425 Use EMACS_INT, not int, for length.

19428 breaking out part of COMPOSITION_DECODE_RULE.
19429 (COMPOSITION_DECODE_RULE): Use it.

19431 by using the new macro.
19433 * textprop.c (set_text_properties_1): Change while to do-while,
19434 since the condition is always true at first.
19436 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19437 (interval_deletion_adjustment): Return unsigned value.
19440 * process.c (list_processes_1, create_pty, read_process_output):

19450 (update_syntax_table): Use unsigned instead of int.
19452 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19453 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19454 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19456 * print.c (print_error_message): Avoid int overflow.
19458 * font.c (font_list_entities): Redo for clarity,
19459 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19461 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19462 (font_score): Avoid potential overflow in diff calculation.
19464 * fns.c (substring_both): Remove var that is set but not used.
19465 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19467 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19469 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19470 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19471 can always succeed if overflow has undefined behavior.
19473 * search.c (boyer_moore, wordify): Remove vars set but not used.
19474 (wordify): Omit three unnecessary tests.
19476 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19477 All callers changed. This avoids the need for an unused var.
19479 * casefiddle.c (casify_region): Remove var that is set but not used.
19481 * dired.c (file_name_completion): Remove var that is set but not used.
19483 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19485 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19486 (Finsert_file_contents): Remove unnecessary code checking fd.
19488 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19489 Check for integer overflow on size calculations.
19491 * buffer.c (Fprevious_overlay_change): Remove var that is set
19494 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19495 Remove vars that are set but not used.
19496 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19497 (timer_check_2): Mark vars as initialized.
19499 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19501 * image.c (lookup_image): Remove var that is set but not used.
19502 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19504 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19505 that are set but not used.
19507 * xfns.c (make_invisible_cursor): Don't return garbage
19508 if XCreateBitmapFromData fails (Bug#8410).
19510 * xselect.c (x_get_local_selection, x_handle_property_notify):
19511 Remove vars that are set but not used.
19513 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19514 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19516 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19517 Remove var that is set but not used.
19518 (scroll_bar_windows_size): Now size_t, not int.
19519 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19520 Check for overflow.
19522 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19523 (map_tty_color) [!defined MSDOS]: Likewise.
19525 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19527 * coding.c: Remove vars that are set but not used.
19528 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19529 All callers changed.
19530 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19531 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19532 (decode_coding_charset): Remove vars that are set but not used.
19534 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19535 that is set but not used.
19537 * print.c (print_object): Remove var that is set but not used.
19539 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19540 The gnulib version avoids calling malloc in the usual case,
19541 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19542 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19543 * filelock.c (current_lock_owner): Likewise.
19544 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19545 * sysdep.c: Include allocator.h, careadlinkat.h.
19546 (emacs_no_realloc_allocator): New static constant.
19547 (emacs_readlink): New function.
19548 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19549 ../lib/careadlinkat.h.
19551 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19553 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

19563 * xdisp.c (display_count_lines): Remove parameter `start',
19564 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

19570 (get_per_char_metric): Remove parameter `f', unused since
19571 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19573 2011-04-02 Jim Meyering <meyering@redhat.com>
19575 do not dereference NULL upon failed strdup
19576 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19577 (ns_get_family): Likewise.
19579 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19581 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19583 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19585 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19588 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19590 Add lexical binding.
19592 * window.c (Ftemp_output_buffer_show): New fun.
19593 (Fsave_window_excursion):
19594 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

19599 Bind Qinternal_interpreter_environment.
19600 (Feval_buffer): Bind Qlexical_binding.
19601 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19603 (syms_of_lread): Declare `lexical-binding'.
19605 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19607 * keyboard.c (eval_dyn): New fun.
19608 (menu_item_eval_property): Use it.
19610 * image.c (parse_image_spec): Use Ffunctionp.
19612 * fns.c (concat, mapcar1): Accept byte-code-functions.
19614 * eval.c (Fsetq): Handle lexical vars.
19615 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19616 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19617 (FletX, Flet): Obey lexical binding.
19618 (Fcommandp): Handle closures.
19619 (Feval): New `lexical' arg.
19620 (eval_sub): New function extracted from Feval. Use it almost
19621 everywhere where Feval was used. Look up vars in lexical env.
19623 (Ffunctionp): Move from subr.el.
19624 (Ffuncall): Handle closures.
19625 (apply_lambda): Remove `eval_flags'.
19626 (funcall_lambda): Handle closures and new byte-code-functions.
19627 (Fspecial_variable_p): New function.
19628 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19629 but without exporting it to Lisp.
19631 * doc.c (Fdocumentation, store_function_docstring):
19632 * data.c (Finteractive_form): Handle closures.
19634 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19637 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19639 (exec_byte_code): New function extracted from Fbyte_code to handle new
19640 calling convention for byte-code-functions. Add new byte-codes.
19642 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19644 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19646 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19648 * xdisp.c (redisplay_internal): Fix prototype.
19650 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19652 * xdisp.c (SCROLL_LIMIT): New macro.
19653 (try_scrolling): Use it when setting scroll_limit.
19654 Limit scrolling to 100 screen lines.
19655 (redisplay_window): Even when falling back on "recentering",
19656 position point in the window according to scroll-conservatively,
19657 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19659 (try_scrolling): When point is above the window, allow searching
19660 as far as scroll_max, or one screenful, to compute vertical
19661 distance from PT to the scroll margin position. This prevents
19662 try_scrolling from unnecessarily failing when
19663 scroll-conservatively is set to a value slightly larger than the
19664 window height. Clean up the case of PT below the margin at bottom
19665 of window: scroll_max can no longer be INT_MAX. When aggressive
19666 scrolling is in use, don't let point enter the opposite scroll
19667 margin as result of the scroll.
19668 (syms_of_xdisp) <scroll-conservatively>: Document the
19669 threshold of 100 lines for never-recentering scrolling.
19671 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19673 * dispextern.h (move_it_by_lines):
19674 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

19676 (message_log_check_duplicate): Remove parameters `prev_bol' and
19677 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19678 (redisplay_internal): Remove parameter `preserve_echo_area',
19679 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19681 * indent.c (Fvertical_motion):
19682 * window.c (window_scroll_pixel_based, Frecenter):
19683 Don't pass `need_y_p' to `move_it_by_lines'.
19685 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19687 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19688 steal a few bits to be more compact.
19689 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19690 Remove unneeded casts.
19692 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19694 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19696 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19697 binding" message (bug#7967).
19699 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19701 Fix more problems found by GCC 4.6.0's static checks.
19703 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19704 Remove unused local var.
19706 * editfns.c (Fmessage_box): Remove unused local var.
19708 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19709 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19710 Omit unused local vars.
19711 * window.c (shrink_windows): Omit unused local var.
19712 * menu.c (digest_single_submenu): Omit unused local var.
19713 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19714 Omit unused local var.
19716 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19717 Don't assume string length fits in int.
19718 (keyremap_step, read_key_sequence): Use size_t for sizes.
19719 (read_key_sequence): Don't check last_real_key_start redundantly.
19721 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19722 instead of alloca (Bug#8344).
19724 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19725 (Fbacktrace_frame): Don't assume nframes fits in int.
19727 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19734 * cm.c (calccost): Turn while-do into do-while, for clarity.
19736 * keyboard.c (syms_of_keyboard): Use the same style as later
19737 in this function when indexing through an array. This also
19738 works around GCC bug 48267.
19740 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19742 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19744 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19745 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19747 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19748 This avoids undefined behavior on integer overflow, and is a bit
19749 more convenient anyway since it is compared to a size_t variable.
19751 Variadic C functions now count arguments with size_t, not int.
19752 This avoids an unnecessary limitation on 64-bit machines, which
19753 caused (substring ...) to crash on large vectors (Bug#8344).

19763 * fns.c (concat): Likewise.
19764 * frame.c (x_set_frame_parameters): Likewise.
19765 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19766 0 if not found, not -1. All callers changed.
19768 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19769 (stack_copy_size): Now size_t, not int.
19770 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19772 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19774 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

19791 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19792 don't set the hook to nil, but remove the offending function instead.
19793 (Qcommand_hook_internal): Remove, unused.
19794 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19795 Vcommand_hook_internal.
19797 * eval.c (enum run_hooks_condition): Remove.
19798 (funcall_nil, funcall_not): New functions.
19799 (run_hook_with_args): Call each function through a `funcall' argument.

19976 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19978 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19979 unconditionally since it does the check itself.
19981 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19983 Fix more problems found by GCC 4.5.2's static checks.
19985 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19986 the first time through the loop, since we know p0 < p1 then.
19987 This also avoids a gcc -Wstrict-overflow warning.
19989 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19990 leading to a memory leak, possible in functions like
19991 load_charset_map_from_file that can allocate an unbounded number
19992 of objects (Bug#8318).
19994 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19995 that could (at least in theory) be that large.
19997 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19998 This is less likely to overflow, and avoids undefined behavior if
19999 overflow does occur. All callers changed. Use strtoul to scan
20000 for the unsigned long integer.
20001 (pint2hrstr): Simplify and tune code slightly.
20002 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20004 * scroll.c (do_scrolling): Work around GCC bug 48228.
20005 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

20012 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20015 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20017 * process.c (Fmake_network_process): Use socklen_t, not int,
20018 where POSIX says socklen_t is required in portable programs.
20019 This fixes a porting bug on hosts like 64-bit HP-UX, where
20020 socklen_t is wider than int (Bug#8277).
20021 (Fmake_network_process, server_accept_connection):
20022 (wait_reading_process_output, read_process_output):
20025 * process.c: Rename or move locals to avoid shadowing.

20035 Make tparam.h and terminfo.c consistent.
20036 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20037 Include tparam.h instead, since it declares them.
20038 * cm.h (PC): Remove extern decl; tparam.h now does this.
20039 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20040 * terminfo.c: Include tparam.h, to check interfaces.
20041 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20042 (tparam): Adjust signature to match interface in tparam.h;
20043 this removes some undefined behavior. Check that outstring and len
20044 are zero, which they always are with Emacs.
20045 * tparam.h (PC, BC, UP): New extern decls.
20047 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20048 (xftfont_open): Rename locals to avoid shadowing.
20050 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

20066 (composition_update_it): Mark var as initialized.
20067 (find_automatic_composition): Mark vars as initialized,
20068 with a FIXME (Bug#8290).

20074 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20075 to avoid shadowing.
20077 * textprop.c (property_change_between_p): Remove; unused.
20079 * intervals.c (interval_start_pos): Now static.
20081 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20087 Fix pointer signedness.
20088 (alsa_choose_format): Remove unused local var.
20089 (wav_play): Initialize a variable to 0, to prevent undefined
20090 behavior (Bug#8278).
20092 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20094 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20096 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20097 clobbering (Bug#8298).
20098 * sysdep.c (sys_subshell): Likewise.
20099 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20101 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20102 This should get cleaned up, so that child_setup has the
20103 same signature on all platforms.
20105 * callproc.c (call_process_cleanup): Now static.
20106 (relocate_fd): Rename locals to avoid shadowing.
20108 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20110 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20111 not to be necessary, and produces flickering.
20113 2011-03-20 Glenn Morris <rgm@gnu.org>
20115 * config.in: Remove file.
20117 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20119 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20120 are now in src/globals.h.
20121 (syms_of_minibuf): Remove spurious & from previous change.

20131 * xfaces.c (Fx_load_color_file):
20132 Read color file from absolute filename (bug#8250).
20134 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20136 * makefile.w32-in: Update dependencies.
20138 2011-03-17 Eli Zaretskii <eliz@gnu.org>

20147 (sigchld_handler): Now static.
20149 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20150 That way, the code declares only the vars that it needs.

20161 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20162 Define only if needed.
20164 * unexelf.c (unexec): Name an expression,
20165 to avoid gcc -Wbad-function-cast warning.
20166 Use a different way to cause a compilation error if anyone uses
20167 n rather than nn, a way that does not involve shadowing.
20168 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20170 * deps.mk (unexalpha.o): Remove; unused.
20172 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20173 * unexec.h: New file.
20174 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20175 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20176 Depend on unexec.h.
20177 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
20178 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
20179 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
20180 Change as necessary to match prototype in unexec.h.
20182 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

20227 * callint.c (quotify_arg, quotify_args): Now static.
20228 (Fcall_interactively): Rename locals to avoid shadowing.

20236 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20237 some of which prompt warnings from gcc -Wbad-function-cast.
20238 (Fformat_time_string, Fencode_time, Finsert_char):
20239 (Ftranslate_region_internal, Fformat):
20240 Rename or remove local vars to avoid shadowing.

20243 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20246 * lisp.h (eassert): Check that the argument compiles, even if
20247 ENABLE_CHECKING is not defined.
20249 * data.c (Findirect_variable): Name an expression, to avoid
20250 gcc -Wbad-function-cast warning.

20262 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
20263 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
20265 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20266 (GC_STRING_CHARS): Remove; not used.
20267 (Fmemory_limit): Cast sbrk's returned value to char *.
20269 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20270 avoids undefined behavior in theory.
20272 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20274 Use functions, not macros, for up- and down-casing (Bug#8254).
20275 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20276 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20277 to use the following functions instead of these macros.
20278 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20279 EMACS_INT, since callers assume the returned value fits in int.
20280 (upcase1): Likewise, for UPCASE_TABLE.
20281 (uppercasep, lowercasep, upcase): New static inline functions.
20282 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20291 which gcc can warn about.
20292 (regex_compile, re_match_2_internal): Mark locals as initialized.
20293 (RETALLOC_IF): Define only if needed.
20294 (WORDCHAR_P): Likewise. This one is never needed, but is used
20295 only in a comment talking about a compiler bug, so put inside
20296 the #if 0 of that comment.
20297 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20298 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20301 * search.c (boyer_moore): Rename locals to avoid shadowing.

20324 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20325 New macros, so that the caller can use some names other than
20326 gcpro1, gcpro2, etc.
20327 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20329 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20330 argument, for consistency with GCPRO2_VAR, etc: it is now the
20331 prefix of the variable, not the variable itself. All uses
20333 * dired.c (directory_files_internal, file_name_completion):
20334 Rename locals to avoid shadowing.
20336 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20337 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20338 dired.c's scmp function, had undefined behavior.
20339 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20340 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20341 * buffer.h: ... to here, because these macros use current_buffer,
20342 and the new implementation with inline functions needs to have
20343 current_buffer in scope now, rather than later when the macros
20345 (downcase, upcase1): New static inline functions.
20346 (DOWNCASE, UPCASE1): Reimplement using these functions.
20347 This avoids undefined behavior in expressions like
20348 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20349 from race conditions in accessing the global variables
20350 case_temp1 and case_temp2.
20351 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20352 * lisp.h (case_temp1, case_temp2): Remove their decls.
20353 * character.h (ASCII_CHAR_P): Move from here ...
20354 * lisp.h: ... to here, so that the inline functions mentioned
20355 above can use them.
20357 * dired.c (directory_files_internal_unwind): Now static.
20359 * fileio.c (file_name_as_directory, directory_file_name):

20362 (file_name_as_directory): Use const pointers when appropriate.
20363 (Fexpand_file_name): Likewise. In particular, newdir might
20364 point at constant storage, so make it a const pointer.
20365 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20366 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20368 (Fset_file_times, Finsert_file_contents, auto_save_error):
20369 Rename locals to avoid shadowing.
20371 * minibuf.c (choose_minibuf_frame_1): Now static.

20373 to avoid shadowing.
20375 * marker.c (bytepos_to_charpos): Remove; unused.
20377 * lisp.h (verify_bytepos, count_markers): New decls,
20378 so that gcc does not warn that these functions aren't declared.
20380 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20381 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20382 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20383 (copy_text): Remove unused local var.
20385 * filelock.c (within_one_second): Now static.
20386 (lock_file_1): Rename local to avoid shadowing.
20388 * buffer.c (fix_overlays_before): Mark locals as initialized.
20389 (fix_start_end_in_overlays): Likewise. This function should be
20390 simplified by using pointers-to-pointers, but that's a different
20392 (switch_to_buffer_1): Now static.
20393 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20394 (report_overlay_modification): Rename locals to avoid shadowing.
20396 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20397 Fix pointer signedness issue.
20398 (sys_subshell): Mark local as volatile if checking for lint,
20399 to suppress a gcc -Wclobbered warning that does not seem to be right.
20400 (MAXPATHLEN): Define only if needed.
20402 * process.c (serial_open, serial_configure): Move decls from here ...
20403 * systty.h: ... to here, so that they can be checked.
20405 * fns.c (get_random, seed_random): Move extern decls from here ...
20406 * lisp.h: ... to here, so that they can be checked.
20408 * sysdep.c (reset_io): Now static.
20409 (wait_for_termination_signal): Remove; unused.
20411 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20412 (copy_keymap_item, append_key, push_text_char_description):
20414 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
20415 (DENSE_TABLE_SIZE): Remove; unused.
20416 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20417 (describe_map_tree):
20418 Rename locals to avoid shadowing.
20420 * keyboard.c: Declare functions static if they are not used elsewhere.
20421 (echo_char, echo_dash, cmd_error, top_level_2):
20422 (poll_for_input, handle_async_input): Now static.

20426 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
20427 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
20428 (read_key_sequence, read_char): Mark locals as initialized.

20435 * lisp.h (force_auto_save_soon): New decl.
20437 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
20438 (DEFINE_DUMMY_FUNCTION): New macro.
20439 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
20441 (main): Add casts to avoid warnings
20442 if GCC considers string literals to be constants.
