15 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
16 fstat shouldn't fail, and if it does fail copy-file should not proceed.

18 function can't copy symlinks. Improve quality of error message
19 when attempting to copy files that are neither regular files nor

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

249 * w32.c (unsetenv): Return 0 if the input string is too long.
251 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

268 no longer needed here.
269 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
270 Move to inside set_time_zone_rule; they don't need file scope any more.
271 (set_time_zone_rule): Maintain the TZ=value string separately.
272 (syms_of_editfns): Don't initialize initial_tz;
273 init_editfns now does it.
274 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
275 * lisp.h (xputenv): New decl.
277 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

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

302 (record_child_status_change, handle_child_signal, deliver_child_signal)

310 (emacs_sigaction_init): Assume SIGCHLD is defined.
311 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,

321 This will cause a production Emacs to dump core instead of
324 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
326 * frame.c (make_frame): Do not set window's buffer to t.
327 * window.c (Fsplit_window_internal): Likewise. Previously it was
328 used to indicate that the window is being set up. Now we use
329 set_window_buffer for all new windows, so the condition in ...
330 (Fset_window_buffer): ... is always true and can be removed.
332 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
334 Convenient macro to check whether the buffer is hidden.
335 * buffer.h (BUFFER_HIDDEN_P): New macro.

342 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
343 if the child process is still running. Instead, exit the wait
344 loop and return zero. (Bug#13086)
346 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
348 * frame.h (x_char_width, x_char_height): Remove prototypes.

357 (command_loop_2, top_level_1): Add static to match prototype.
359 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
361 Fix a recently-introduced delete-process race condition.
362 * callproc.c, process.h (record_kill_process):
363 New function, containing part of the old call_process_kill.
364 (call_process_kill): Use it.
365 This does not change call_process_kill's behavior.
366 * process.c (Fdelete_process): Use record_kill_process to fix a
367 race condition that could cause Emacs to lose track of a child.
369 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
371 Avoid code duplication between prev_frame and next_frame.
372 * frame.c (candidate_frame): New function. Add comment.
373 (prev_frame, next_frame): Use it. Adjust comment.
375 2012-12-06 Eli Zaretskii <eliz@gnu.org>
377 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
378 fails, signal an error instead of continuing with an empty
380 Encode expanded temp file pattern before passing it to mkstemp or
383 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
384 Encode the file name before passing it to dostounix_filename, in
385 case it will downcase it (under w32-downcase-file-names).
388 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
390 Minor call-process cleanups.
391 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
392 at the same time as other platforms, to simplify analysis.
393 No need for fd0_volatile since we have synch_process_fd.
394 Avoid needless emacs_close; arg is always negative.
396 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
398 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
401 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
403 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
404 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
405 and mouse_face_hidden members to a bitfields.
406 * frame.h (struct frame): Remove set-but-not-used space_width member.
407 (FRAME_SPACE_WIDTH): Remove.

410 member. Adjust users. Convert term_initted, delete_in_insert_mode,
411 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
412 members to a bitfields.
414 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
416 Don't let call-process be a zombie factory (Bug#12980).
417 Fixing this bug required some cleanup of the signal-handling code.
418 As a side effect, this change also fixes a longstanding rare race
419 condition whereby Emacs could mistakenly kill unrelated processes,
420 and it fixes a bug where a second C-g does not kill a recalcitrant
421 synchronous process in GNU/Linux and similar platforms.
422 The patch should also fix the last vestiges of Bug#9488,
423 a bug which has mostly been fixed on the trunk by other changes.
424 * callproc.c, process.h (synch_process_alive, synch_process_death)
425 (synch_process_termsig, sync_process_retcode):
426 Remove. All uses removed, to simplify analysis and so that
427 less consing is done inside critical sections.
428 * callproc.c (call_process_exited): Remove. All uses replaced
429 with !synch_process_pid.
430 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
431 These take the role of what used to be in unwind-protect arg.
433 (block_child_signal, unblock_child_signal):
434 New functions, to avoid races that could kill innocent-victim processes.
435 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
436 (call_process_kill): Record killed processes as deleted, so that
437 zombies do not clutter up the system. Do this inside a critical
438 section, to avoid a race that would allow the clutter.
439 (call_process_cleanup): Fix code so that the second C-g works again
440 on common platforms such as GNU/Linux.
441 (Fcall_process): Create the child process in a critical section,
442 to fix a race condition. If creating an asynchronous process,
443 record it as deleted so that zombies do not clutter up the system.
444 Do unwind-protect for WINDOWSNT too, as that's simpler in the
445 light of these changes. Omit unnecessary call to emacs_close
446 before failure, as the unwind-protect code does that.
447 * callproc.c (call_process_cleanup):
448 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
449 * process.c (record_deleted_pid): New function, containing
450 code refactored out of Fdelete_process.
451 (Fdelete_process): Use it.
452 (process_status_retrieved): Remove. All callers changed to use
454 (record_child_status_change): Remove, folding its contents into ...
455 (handle_child_signal): ... this signal handler. Now, this
456 function is purely a handler for SIGCHLD, and is not called after
457 a synchronous waitpid returns; the synchronous code is moved to
458 wait_for_termination. There is no need to worry about reaping
459 more than one child now.
460 * sysdep.c (get_child_status, child_status_changed): New functions.
461 (wait_for_termination): Now takes int * status and bool
462 interruptible arguments, too. Do not record child status change;
463 that's now the caller's responsibility. All callers changed.
464 Reimplement in terms of get_child_status.
465 (wait_for_termination_1, interruptible_wait_for_termination):
466 Remove. All callers changed to use wait_for_termination.
467 * syswait.h: Include <stdbool.h>, for bool.
468 (record_child_status_change, interruptible_wait_for_termination):
470 (record_deleted_pid, child_status_changed): New decls.
471 (wait_for_termination): Adjust to API changes noted above.
473 * bytecode.c, lisp.h (Qbytecode): Remove.
474 No longer needed after 2012-11-20 interactive-p changes.
476 2012-12-03 Eli Zaretskii <eliz@gnu.org>
478 * xdisp.c (redisplay_window): If the cursor is visible, but inside
479 the scroll margin, move point outside the margin. (Bug#13055)
481 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
483 * gtkutil.c (my_log_handler): New function.
484 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
486 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
488 * lisp.h (modify_region): Rename to...
489 (modify_region_1): ...new prototype.
490 * textprop.c (modify_region): Now static. Adjust users.
491 * insdel.c (modify_region): Rename to...
492 (modify_region_1): ...new function to work with current buffer.
493 Adjust comment and users. Use true and false for booleans.
495 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
497 * alloc.c (free_save_value): New function.
498 (safe_alloca_unwind): Use it.

530 Fix xpalloc confusion after memory is exhausted.
531 * alloc.c (xpalloc): Comment fix.
532 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
533 and signals an error, do not clear charset_table_size, as
534 charset_table is still valid.
535 * doprnt.c (evxprintf): Clear *BUF after freeing it.
537 Use execve to avoid need to munge environ (Bug#13054).
538 * callproc.c (Fcall_process):
539 * process.c (create_process):
540 Don't save and restore environ; no longer needed.
541 * callproc.c (child_setup):
542 Use execve, not execvp, to preserve environ.
544 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
546 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

550 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
551 display for sliced images (Bug#10500).
553 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
555 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
557 * doc.c (Fdocumentation): Re-add handling of function-documentation,
558 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).

571 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
573 * callproc.c (Fcall_process): Don't misreport vfork failure.
575 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
577 * callproc.c (Fcall_process): Fix vfork portability problems.
578 Do not assume that fd[0], count, filefd, and save_environ survive
579 vfork. Fix bug whereby wrong errno value could be reported for
580 pipe failure. Some minor cleanups, too, as follows. Move buf and
581 bufsize to the context where they're needed. Change new_argv to
582 be of type char **, as this is more convenient and avoids casts.
583 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
584 Now local constants, not macros.
586 2012-11-18 Kenichi Handa <handa@gnu.org>
588 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
589 for the variable "f".

593 * font.c (font_unparse_xlfd): Exclude special characters from the
594 generating XLFD name.

634 2012-11-24 Eli Zaretskii <eliz@gnu.org>
636 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
637 between bpos_covered and bpos_max. This fixes cursor display when
638 several display strings follow each other.
640 * .gdbinit (pgx): If the glyph's object is a string, display the
641 pointer to string data, rather than the value of the string object
642 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
644 * indent.c (Fvertical_motion): If the starting position is covered
645 by a display string, return to one position before that, to avoid
646 overshooting it inside move_it_to. (Bug#12930)
648 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
650 * frame.h (struct frame): Remove display_preempted member

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

667 of a literal "/". (Bug#12955)
668 (gl-stamp): Invoke fc.exe directly, not through cmd.
670 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
672 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
673 * dired.c: Assume HAVE_DIRENT_H.
674 (NAMLEN): Remove, replacing with ...
675 (dirent_namelen): New function. All uses changed. Use the GNU macro
676 _D_EXACT_NAMELEN if available, as it's faster than strlen.
677 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
678 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
679 * makefile.w32-in (DIR_H): Remove. All uses replaced with

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

687 2012-11-23 Chong Yidong <cyd@gnu.org>
689 * xftfont.c (xftfont_open): Remove duplicate assignment.
691 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
693 * alloc.c (Fgarbage_collect): Unblock input after clearing
694 gc_in_progress to avoid note_mouse_highlight glitch with GC.
695 * frame.h (FRAME_MOUSE_UPDATE): New macro.
696 * msdos.c (IT_frame_up_to_date): Use it here...
697 * w32term.c (w32_frame_up_to_date): ...here...
698 * xterm.c (XTframe_up_to_date): ...and here...
699 * nsterm.m (ns_frame_up_to_date): ...but not here.
700 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
702 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

709 simplify large 'if' statements.
710 (redisplay_internal): Generalize commonly used
711 'tail' and 'frame' local variables.
713 2012-11-22 Eli Zaretskii <eliz@gnu.org>
715 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
716 with Windows system header.
718 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
720 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
721 * alloc.c: Assume unistd.h exists.
722 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
723 * sysdep.c (get_current_dir_name): Assume getcwd exists.
724 (getwd) [USG]: Remove; no longer needed.

737 * emacs.c (main): Set the G_SLICE environment variable for all
738 Cygwin builds, not just GTK builds. See
739 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
741 2012-11-21 Eli Zaretskii <eliz@gnu.org>
743 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
744 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
745 Define for the MSVC compiler.
747 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
749 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
750 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
751 dostounix_filename. Prevents crashes down the road, because
752 dostounix_filename assumes it gets a unibyte string. Reported by
753 Michel de Ruiter <michel@sentient.nl>, see
754 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
756 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

780 (text_outside_line_unchanged_p, redisplay_window): Use it.
781 (redisplay_internal): Likewise. Fix indentation.
783 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
785 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
786 (syms_of_eval): Remove corresponding defsubr.
787 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
789 2012-11-19 Daniel Colascione <dancol@dancol.org>
791 * w32fns.c (Fx_file_dialog):
792 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
793 cygwin_convert_file_name*.

796 Rename cygwin_convert_path* to cygwin_convert_file_name*.
798 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
800 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
802 2012-11-18 Eli Zaretskii <eliz@gnu.org>
804 * w32select.c: Include w32common.h before w32term.h, so that
805 windows.h gets included before w32term.h uses some of its
808 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
810 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
812 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
814 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
816 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).

822 Needed following 2012-10-20 change. (Bug#12902)
824 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
826 * w32proc.c (waitpid): Remove unused label get_result.
828 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
830 * makefile.w32-in (SYSWAIT_H): New macro.
831 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
832 ($(BLD)/sysdep.$(O)): Update dependencies.
834 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
836 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
837 * callproc.c (relocate_fd): Assume F_DUPFD.
838 * emacs.c, term.c (O_RDWR): Remove.
839 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
840 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
841 * nsterm.m: Assume <fcntl.h> exists.
842 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
843 (create_pty, Fmake_network_process, server_accept_connection)
844 (wait_reading_process_output, init_process_emacs):
846 (wait_reading_process_output): Put in a special case for WINDOWSNT
847 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
848 It's not clear this is needed, but it's a more-conservative change.
849 (create_process): Assume FD_CLOEXEC.
850 (create_process, create_pty): Assume O_NOCTTY.
851 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
852 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.

855 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
857 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
858 lack it, since gnulib guarantees this.
859 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
861 2012-11-17 Eli Zaretskii <eliz@gnu.org>
863 * w32.c (faccessat): Pretend that directories have the execute bit
864 set. Emacs expects that, e.g., in files.el:cd-absolute.
866 * w32proc.c (create_child): Don't clip the PID of the child
867 process to fit into an Emacs integer, as this is no longer a
869 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
870 reaping only the process specified by PID argument, if that is
871 positive. Use PID instead of dead_child to know which process to
872 reap. Wait for the child to die only if WNOHANG is not in
874 (sys_select): Don't set dead_child.
876 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
877 as it is no longer needed.
879 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
881 (record_child_status_change): Remove the setting of
882 record_at_most_one_child for the !WNOHANG case.
884 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
886 Fix problems in ns port found by static checking.
887 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
888 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
889 not to process group.
890 (ns_select): Use emacs_write, not write, as that's more robust
891 in the presence of signals.
892 (fd_handler:): Check for read errors.
894 2012-11-16 Glenn Morris <rgm@gnu.org>
896 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
898 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
900 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
902 2012-11-16 Eli Zaretskii <eliz@gnu.org>
904 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
905 use the same value of thread handle.
906 (start_timer_thread): If the timer thread exited (due to error),
907 clean up by closing the two handles it used. Duplicate the caller
908 thread's handle here, so it gets duplicated only once, when
909 launching the timer thread. Set priority of the timer thread, not
911 (getitimer): Don't duplicate the caller thread's handle here.
914 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
916 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
919 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
921 Remove no-longer-used pty_max_bytes variable.
922 * process.c (pty_max_bytes): Remove; unused.
923 (send_process): Do not set it.
925 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
927 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
930 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
932 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
933 This follows up on the 2012-09-29 patch that removed indirection
934 for the 'function' field. Reported by Sergey Vinokurov in
935 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
937 2012-11-14 Eli Zaretskii <eliz@gnu.org>
939 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
940 different name, as the MS runtime does not have such a function,
941 and probably never will.) All callers changed. Ignore DIRFD
942 value if PATH is an absolute file name, to match Posix spec
943 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
946 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
948 * xdisp.c (echo_area_display, redisplay_internal):
949 Omit redundant check whether frame_garbaged is set.
951 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
953 Use faccessat, not access, when checking file permissions (Bug#12632).
954 This fixes a bug that has been present in Emacs since its creation.
955 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
956 which must set some sort of record. (Torek's bug report was against
957 a predecessor of GNU Emacs, but GNU Emacs happened to have the
958 same common flaw.) See Torek's Usenet posting
959 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
960 Posted: Fri Apr 8 14:18:56 1983.

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

1028 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1030 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1031 passed to pint2str and pint2hrstr to be at most the size of the
1032 frame's decode_mode_spec_buffer. This avoids crashes with very
1033 large values of FIELD_WIDTH argument to decode_mode_spec.
1036 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1038 Fix a race with verify-visited-file-modtime (Bug#12863).
1039 Since at least 1991 Emacs has ignored an mtime difference of no
1040 more than one second, but my guess is that this was to work around
1041 file system bugs that were fixed long ago. Since the race is
1042 causing problems now, let's remove that code.
1043 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1044 whose time stamp is off by no more than a second. Insist that the
1045 file time stamps match exactly.
1047 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1049 * frame.h (struct frame): Convert external_tool_bar member to
1050 1-bit unsigned bitfield.

1052 all users are long dead. Adjust comment on mouse_position_hook.
1054 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1056 Simplify by using FOR_EACH_FRAME here and there.
1057 * frame.c (next_frame, prev_frame, other_visible_frames)
1058 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1059 * w32term.c (x_window_to_scroll_bar): Likewise.
1060 * window.c (window_list): Likewise.
1061 * xdisp.c (x_consider_frame_title): Likewise.
1062 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.

1064 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1065 * xmenu.c (menubar_id_to_frame): Likewise.
1066 * xselect.c (frame_for_x_selection): Likewise.
1067 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1068 (x_window_to_menu_bar): Likewise.
1069 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1071 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1073 * data.c (Qdefalias_fset_function): Now static.
1075 Another tweak to vectorlike_header change.

1077 Remove, and replace all uses with ...
1078 (next_in_free_list, set_next_in_free_list):
1079 New functions, which respect C's aliasing rules better.
1081 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1083 * window.c (list4i): Rename from 'quad'. All uses changed.
1084 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1086 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1088 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1089 warning about mixing declarations and code in ISO C90.
1091 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1093 * window.c (Fsplit_window_internal): Set combination limit of
1094 new parent window to t iff Vwindow_combination_limit is t;
1095 fixing a regression introduced with the change from 2012-09-22.
1096 (Fset_window_combination_limit): Fix doc-string.
1098 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1100 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1101 amount when the scroll margins are too large. When scrolling
1102 backwards in the buffer, give up if cannot reach point or the
1103 scroll margin within a reasonable number of screen lines.
1104 Fixes point position in window under scroll-up/down-aggressively when
1105 point is positioned many lines beyond the window top/bottom.
1108 * ralloc.c (relinquish): If real_morecore fails to return memory
1109 to the system, don't crash; instead, leave the last heap
1110 unchanged and return. (Bug#12774)
1112 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1114 * lisp.h (AUTOLOADP): New macro.

1119 (Finteractive_form): Simplify.
1120 (Fquo): Don't insist on having at least 2 arguments.
1121 (Qdefalias_fset_function): New var.
1123 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1125 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1127 * nsfont.m (Qcondensed, Qexpanded): New variables.

1131 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1133 Fix recently introduced crash on MS-Windows (Bug#12839).
1134 * w32term.h (struct scroll_bar): Use convenient header.
1135 (SCROLL_BAR_VEC_SIZE): Remove.
1136 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1138 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1140 Tweak last vectorlike_header change.
1141 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1142 vectorlike object on the free list. This is introduced to avoid
1143 some (but not all) pointer casting and aliasing problems, see
1144 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1145 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1149 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1151 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1152 been removed, so remove them here also.
1154 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1156 * doc.c (Fdocumentation): Handle new property
1157 dynamic-docstring-function to replace the old ad-advice-info.

1177 special hash function containing a comparison that always yields 1.
1179 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1181 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1182 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1183 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1186 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1188 * image.c (xpm_make_color_table_h): Fix compiler error because

1193 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1195 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1197 Use ad-hoc comparison function for the profiler's hash-tables.
1198 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1199 (make_log): Use them.
1200 (handle_profiler_signal): Don't inhibit quit any longer since we don't

1250 (Fmake_bool_vector): Likewise.
1251 (struct large_vector): New type to represent allocation unit for
1252 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1253 (large_vectors): Change type to struct large_vector.
1254 (allocate_vector_from_block): Simplify.
1255 (PSEUDOVECTOR_NBYTES): Replace with...

1277 * keyboard.c (event_to_kboard): Do not dereference
1278 frame_or_window field of SELECTION_REQUEST_EVENT
1279 and SELECTION_CLEAR_EVENT events (Bug#12814).

1282 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1284 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1285 such as Scroll Lock, if the respective keys are treated as
1286 function keys, not as modifiers. This avoids destroying non-ASCII
1287 keyboard input when Scroll Lock is toggled ON. (Bug#12806)

1291 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1293 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1295 Restore some duplicate definitions (Bug#12814).
1296 This undoes part of the 2012-11-03 changes. Some people build
1297 with plain -g rather than with -g3, and they need the duplicate
1298 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1299 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):

1305 to keypad keys (Bug#12816).
1307 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1309 Minor adjustments of recently-changed frame functions.
1310 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1311 known to be a frame (we're in the FRAMEP branch).
1312 * lisp.h (Qframep): Remove decl. frame.h declares this.
1313 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1314 since they're meant for Lisp fixnum values.
1316 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1318 * window.c (Fwindow_combination_limit): Revert to the only
1319 required argument and adjust docstring as suggested in
1320 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1321 by Martin Rudalics <rudalics@gmx.at>.

1374 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1375 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1376 file descriptor 2 for standard error. (Bug#12805)
1378 2012-11-05 Chong Yidong <cyd@gnu.org>
1380 * process.c (wait_reading_process_output): Revert previous change.
1382 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1384 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1385 This removes code that has been obsolete since around 1990.
1386 * callproc.c (Fcall_process):
1388 * process.c (create_process):
1389 * term.c (dissociate_if_controlling_tty):

1411 Remove EMACS_OUTQSIZE+sleep hack.
1412 * dispnew.c (update_frame_1): Remove hack for terminals slower
1413 than 2400 bps, which throttled Emacs by having it sleep.
1414 This code hasn't worked since at least 2007, when the multi-tty stuff
1415 was added, and anyway those old terminals are long dead.
1416 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1417 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1419 Fix data-loss with --version (Bug#9574).
1420 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1421 as we can't assume that emacs_strerror is initialized, and strerror
1422 is good enough here.
1423 (main): Invoke atexit earlier, to catch earlier instances of
1424 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1426 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1428 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1429 (keyDown): Remap keypad keys to X11 virtual key codes.
1431 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1433 Fix data-loss with --batch (Bug#9574).
1434 * emacs.c: Include <close-stream.h>.
1435 (close_output_streams): New function.
1436 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1437 and handles errors appropriately.
1438 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1441 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1442 The symptom is a diagnostic "GLib-WARNING **: In call to
1443 g_spawn_sync(), exit status of a child process was requested but
1444 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1445 waitpid(), so exit status can't be returned." The diagnostic
1446 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1447 The real bug is a race condition between Emacs and glib: Emacs
1448 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1449 so that glib can't find it. Work around the bug by invoking
1450 waitpid only on subprocesses that Emacs itself creates.
1451 * process.c (create_process, record_child_status_change):
1452 Don't use special value -1 in pid field, as the caller now must
1453 know the pid rather than having the callee infer it.
1454 The inference was sometimes incorrect anyway, due to another race.
1455 (create_process): Set new 'alive' member if child is created.
1456 (process_status_retrieved): New function.
1457 (record_child_status_change): Use it.
1458 Accept negative 1st argument, which means to wait for the
1459 processes that Emacs already knows about. Move special-case code
1460 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1461 processes that have already been waited for, by testing and
1462 clearing new 'alive' member.
1463 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1464 now does this internally.
1465 (handle_child_signal): Let record_child_status_change do all
1466 the work, since we do not want to reap all exited child processes,
1467 only the child processes that Emacs itself created.
1468 * process.h (Lisp_Process): New boolean member 'alive'.
1470 Omit duplicate definitions no longer needed with gcc -g3.
1471 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1472 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1473 Define only as macros. There's no longer any need to also define
1474 these symbols as enums or as constants, since we now assume
1475 gcc -g3 when debugging.
1477 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1479 * lisp.mk: Adjust comments to the fact that term/internal is now
1480 loaded from loadup.el.
1482 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1483 (msdos_fatal_signal): New function.
1484 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1487 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1488 for GCC versions before 4.
1489 (emacs_raise): Define to call msdos_fatal_signal.
1491 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1492 iterator when starting in the middle of a display or overlay
1495 2012-11-03 Chong Yidong <cyd@gnu.org>
1497 * process.c (wait_reading_process_output): Clean up the last
1500 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1502 * process.c (wait_reading_process_output): Avoid a race condition
1503 with SIGIO delivery (Bug#11536).
1505 2012-11-03 Chong Yidong <cyd@gnu.org>
1507 * buffer.c (cursor_type): Untabify docstring.
1509 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1511 * frame.h (struct frame): Drop can_have_scroll_bars member
1512 which is meaningless for a long time. Adjust comments.
1513 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1514 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1516 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1518 * window.c (decode_next_window_args): Update window arg after
1519 calling decode_live_window and so fix crash reported at
1520 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1521 by Juanma Barranquero <lekktu@gmail.com>.
1522 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1523 * font.c (Ffont_at): Likewise.
1525 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1527 * widget.c (resize_cb): New function.
1528 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1529 (EmacsFrameResize): Check if all is up to date before changing frame
1532 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1534 Implement backtrace output for fatal errors on MS-Windows.
1535 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1536 (BACKTRACE_LIMIT_MAX): New macro.
1537 (w32_backtrace): New function.
1538 (emacs_abort): Use w32_backtrace when the user chooses not to
1539 attach a debugger. Update the text of the abort dialog.
1541 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1543 Window-related stuff cleanup here and there.
1544 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1545 Use decode_any_window.
1546 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1547 * xdisp.c (Fformat_mode_line): Likewise.
1548 * font.c (Ffont_at): Use decode_live_window.
1549 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1550 * window.c (decode_next_window_args): Likewise.
1551 (decode_any_window): Remove static.
1552 * window.h (decode_any_window): Add prototype.
1553 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1554 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1557 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1559 Remove pad from struct input_event.
1560 * termhooks.h (struct input_event): Remove padding field.
1562 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1563 member is never cons for a long time. Adjust comment.
1564 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1565 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1566 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1567 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1569 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1571 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1573 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1575 Fix crash when using Emacs as commit editor for git (Bug#12697).
1576 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1577 and it is configured in conf_post.h.
1578 (Fcall_process): Don't invoke both setsid and setpgid; the former
1579 is enough, if it exists.
1580 * callproc.c (Fcall_process, child_setup):
1581 * process.c (create_process): Use setpgid.
1582 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1584 * dispnew.c (init_display): Initialize the foreground group
1585 if we are running a tty display.
1586 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1587 * lisp.h (init_foreground_group): New decl.
1588 * sysdep.c (inherited_pgroup): New static var.
1589 (init_foreground_group, tcsetpgrp_without_stopping)
1590 (narrow_foreground_group, widen_foreground_group): New functions.
1591 (init_sys_modes): Narrow foreground group.
1592 (reset_sys_modes): Widen foreground group.
1594 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1596 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1598 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1600 * minibuf.c (read_minibuf): Restore current buffer since
1601 choose_minibuf_frame calling Fset_frame_selected_window may
1602 change it (Bug#12766).
1604 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1606 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1608 2012-10-30 Kenichi Handa <handa@gnu.org>
1610 * font.c (Ffont_at): If WINDOW is specified and it is not
1611 displaying the current buffer, signal an error.
1613 2012-10-29 Daniel Colascione <dancol@dancol.org>
1615 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1616 In preparation for fixing bug#12739, move these functions from
1619 * coding.h, coding.c: ... to here, and compile them only when
1620 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1621 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1623 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1625 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1626 (timer_loop, getitimer, setitimer): Use it instead of
1627 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1629 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1632 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1634 * nsterm.m (NO_APPDEFINED_DATA): New define.
1635 (last_appdefined_event_data): New variable
1636 (last_appdefined_event): Remove.
1637 (ns_select): Initialize t from last_appdefined_event_data instead
1638 of [last_appdefined_event data1].
1639 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1640 remove last_appdefined_event (Bug#12698).
1642 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1644 * frame.c (x_set_font): Catch internal error.
1646 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1648 Avoid overflow in w32 implementation of interval timers.
1649 When possible, for ITIMER_PROF count only times the main thread
1651 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1652 'volatile ULONGLONG' types. All the other data which was
1653 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1654 (GetThreadTimes_Proc): New typedef.
1655 (w32_get_timer_time): New function, returns a suitable time value
1657 (timer_loop): Enter critical section when accessing ULONGLONG
1658 values of the itimer_data struct, as these accesses are no longer
1659 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1660 Remove unused variable.
1661 (init_timers): Initialize s_pfn_Get_Thread_Times.
1662 (start_timer_thread): Don't assign itimer->caller_thread here.
1663 (getitimer): Assign itimer->caller_thread here.
1664 (setitimer): Always call getitimer to get the value of ticks_now.
1665 (sys_spawnve): Avoid compiler warning about format mismatch.
1667 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1669 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1670 mouse movement events if the menu bar is active. This avoids
1671 producing a busy "hour-glass" cursor by Windows if the mouse
1672 pointer is positioned over a tooltip shown for some menu item.
1674 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1676 Don't assume process IDs fit in int.
1677 * emacs.c (shut_down_emacs) [!DOS_NT]:
1678 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1679 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1680 Use pid_t, not int, to store process IDs, as 'int'
1681 is not wide enough on a few platforms (e.g., AIX and IRIX).
1683 2012-10-23 Kenichi Handa <handa@gnu.org>
1685 The following change is to make face-font-rescale-alist work
1686 correctly for non-ASCII fonts.
1688 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1689 (font_open_for_lface): Handle Vface_font_rescale_alist.
1691 2012-10-23 Chong Yidong <cyd@gnu.org>
1693 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1695 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1697 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1699 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1701 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1704 2012-10-21 Glenn Morris <rgm@gnu.org>
1706 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1708 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1710 Port to OpenBSD 5.1.
1711 * frame.c (Fmouse_position, Fmouse_pixel_position):
1712 * xdisp.c (produce_stretch_glyph):
1713 Declare local vars only when they're needed.
1714 This is clearer and avoids a warning on OpenBSD about unused vars.
1715 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1716 This is safer, and avoids OpenBSD warnings about unused vars.
1717 * keyboard.c (record_menu_key): Remove unnecessary decl.
1718 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1719 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1720 as our definition clashes with OpenBSD's.
1721 * xfaces.c (load_face_colors, check_lface_attrs)
1722 (get_lface_attributes_no_remap, get_lface_attributes)
1723 (lface_fully_specified_p, x_supports_face_attributes_p)
1724 (tty_supports_face_attributes_p, face_fontset, realize_face)
1725 (realize_x_face, realize_tty_face):
1726 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1727 merely Lisp_Object *. This is more informative and avoids
1728 a warning on OpenBSD about accessing beyond an object's size.
1730 2012-10-20 Chong Yidong <cyd@gnu.org>
1732 * lread.c (Fload): Doc fix (Bug#12592).
1734 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1736 * font.c (Ffont_at): Fix previous change.
1738 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1740 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1741 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

1751 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1753 * nsterm.m (ns_select): Check writefds before call to
1754 FD_ISSET (Bug#12668).
1756 2012-10-18 Daniel Colascione <dancol@dancol.org>
1758 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1759 (staticpro): If we run out of staticpro slots, die with an
1760 informative error instead of just calling emacs_abort.
1762 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1764 Fix two flaws reported by Dmitry Antipov.
1765 * window.c (Ftemp_output_buffer_show): Remove.
1766 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
1767 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.

1785 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
1786 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1787 (sys_link): Add prototypes.
1789 * w32.c: Include w32select.h.
1790 (sys_access, e_malloc, sys_select): Add prototypes.
1791 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.

1795 * unexw32.c: Include lisp.h and w32.h.
1797 * term.c [WINDOWSNT]: Include w32term.h.

1801 * fileio.c [WINDOWSNT]: Include w32.h.
1803 * dispnew.c [WINDOWSNT]: Include w32.h.
1805 * cygw32.c (Fcygwin_convert_path_to_windows)
1806 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
1807 Lisp_Object values. (Bug#12661)
1809 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
1810 to Lisp_Object. (Bug#12661)
1812 2012-10-17 Kenichi Handa <handa@gnu.org>

1822 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
1824 Do not verify indirection counters of killed buffers (Bug#12579).
1825 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
1826 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.

1846 2012-10-15 Martin Rudalics <rudalics@gmx.at>
1848 * window.c (Fwindow_end): Rewrite check whether cached position
1849 can be used (Bug#12600).

1851 Set windows_or_buffers_changed.
1853 2012-10-15 Daniel Colascione <dancol@dancol.org>
1855 * dbusbind.c: Fix cygw32 build break when compiling with dbus
1856 enabled by undefining the symbol "interface", which the platform
1857 headers define to something incompatible.

1878 2012-10-13 Andreas Schwab <schwab@linux-m68k.org>
1880 * fileio.c: Formatting fixes.
1882 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
1884 Fix some stat-related races.
1885 * fileio.c (Fwrite_region): Avoid race condition if a file is
1886 removed or renamed by some other process immediately after Emacs
1887 writes it but before Emacs stats it. Do not assume that stat (or
1889 * image.c (slurp_file): Resolve the file name with fopen + fstat
1890 rather than stat + fopen.

1908 is zero (Bug#12384).
1910 2012-10-12 Juanma Barranquero <lekktu@gmail.com>

1916 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
1918 * fileio.c (check_existing): New function.
1919 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1920 instead of calling 'stat', when what's needed is to check whether
1921 a file exists. This avoids expensive system calls on MS-Windows.
1924 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1926 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
1927 determine whether a file exists and is not a directory.
1929 * lisp.h (check_existing): Add prototype.
1931 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
1933 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

1963 Use bool for booleans.
1964 * lread.c (safe_to_load_version): Rename from safe_to_load_p,

1968 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
1970 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.
1971 (save_excursion_restore): Do not restore mark if it was not saved.
1973 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
1975 * marker.c (cached_modiff): EMACS_INT, not int.
1977 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
1978 instead of having a wrong decl.

2017 * process.c (wait_reading_process_output):
2018 Use unsigned for counter where wraparound-on-overflow is desired,
2019 since unsigned is guaranteed to have that behavior and signed is not.
2020 (read_char): Use ptrdiff_t for string length.
2021 (get_input_pending): Remove first argument, since it was always
2022 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2023 and behave as if it had that value. Return new value of
2024 input_pending. All callers changed.
2025 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2026 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2028 * keymap.c (push_key_description): Omit last arg, which was always 1.
2029 All callers changed.
2031 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
2033 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

2049 Don't include termopts.h.
2051 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2053 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2055 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2057 * commands.h (immediate_quit): Remove duplicate decl.
2059 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2061 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
2063 (nsfont_open): Remove setting of Vfonts_in_cache.
2064 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2066 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2068 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2069 match what GetLastError returns. Explain why the function is
2072 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2073 'is_tooltip_frame', to avoid confusion with its global namesake.
2075 2012-10-08 Daniel Colascione <dancol@dancol.org>
2077 * xdisp.c (start_hourglass): Call w32_note_current_window when
2078 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2079 build that caused Emacs to display the hourglass cursor forever.
2081 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2082 which is broken under remote desktop, calculate the number of
2083 colors available for a display based on the display's number of
2084 planes and number of bits per pixel per plane. (bug#10397).
2086 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2088 * nsfont.m (Vfonts_in_cache): New variable.
2089 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2090 are used. Add cached fonts to Vfonts_in_cache.
2091 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2093 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2095 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2097 (FONT_H): Define after FRAME_H.
2098 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2099 Update dependencies.
2101 * w32term.c: Remove leftover declaration of keyboard_codepage.
2103 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2105 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2106 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2107 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2108 (GLOBAL_SOURCES): Add cygw32.c.
2109 ($(BLD)/unexw32.$(O)):
2111 ($(BLD)/w32console.$(O)):
2112 ($(BLD)/w32fns.$(O)):
2113 ($(BLD)/w32heap.$(O)):
2114 ($(BLD)/w32menu.$(O)):
2115 ($(BLD)/w32proc.$(O)): Add w32common.h.
2117 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2119 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2121 2012-10-08 Daniel Colascione <dancol@dancol.org>
2123 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2124 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2125 accidental message numbering hole. Change other messages to
2128 * w32select.h (HAVE_W32SELECT): Remove.
2130 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2131 w32common.h instead of w32heap.h.
2133 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2134 (get_allocation_unit, get_processor_type, get_w32_major_version)
2135 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2136 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2137 (OS_NT, os_subtype, cache_system_info): Move declarations to
2140 * w32heap.c: Include w32common.h.
2141 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2142 (w32_minor_version, w32_build_number, w32_subtype):
2143 Remove duplicate definitions.
2145 * w32fns.c: Include w32common.h; include w32heap.h only in
2148 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2149 Use `report_file_error' instead of `error' in order to better
2150 inform users of what went wrong. Increase NTGUI_UNICODE file
2151 dialog box file name length to 32k, the maximum allowed by the NT
2154 * w32common.h: New file.
2155 (ROUND_UP, ROUND_DOWN, get_page_size)
2156 (get_allocation_unit, get_processor_type, get_w32_major_version)
2157 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2158 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2159 (OS_NT, os_subtype, cache_system_info): Move here.
2161 * unexw32.c, unexcw.c: Include w32common.h.
2163 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2164 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2165 to call syms_of_w32select.
2167 * cygw32.h: Remove obsolete EXFUN declarations.
2169 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2171 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2172 of w32inevt.o from SOME_MACHINE_OBJECTS.
2174 2012-10-08 Daniel Colascione <dancol@dancol.org>
2176 * image.c: Permanent fix for JPEG compilation issue --- limit
2177 jpeglib `boolean' redefinition to Cygwin builds.
2179 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2181 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2183 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2186 2012-10-08 Daniel Colascione <dancol@dancol.org>
2188 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2189 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2190 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2191 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2192 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2193 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2194 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2195 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2196 now a supported configuration.
2198 * Makefile.in: consolidate image variables into LIBIMAGE; add
2199 W32_OBJ and W32_LIBS. Compile new files.
2202 (_DebPrint) declare tracing facility for W32 debugging. We need
2203 to unify tracing later.
2205 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2206 unconditional use of W32 Unicode functions. Cygwin runs only on
2207 100% Unicode operating systems.
2209 * cygw32.c: New file. Define Cygwin-specific facilities.
2210 (Fcygwin_convert_path_to_windows)
2211 (Fcygwin_convert_path_from_windows): New user functions for
2212 accessing Cygwin path-munging routines.
2214 * cygw32.h: New file.
2215 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2216 UTF-16LE strings temporarily inside non-Lisp-visible string
2219 (w32_strerror): Just what it says on the tin.
2221 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2222 also run for Cygwin; both systems have the same problem with using
2223 GUI facilities in a forked child. Also call syms_of_cygw32,
2224 syms_of_w32select in correct places.
2226 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2227 needs fork-then-exec for daemon launching.
2229 * font.h: Include frame.h.
2231 * image.c: Use the image library cache machinery only when we're
2232 compiling for native WINDOWSNT; Cygwin can use shared libraries
2233 like any other Unixlike system.
2235 * keyboard.c: Clarify a comment regarding the input loop.
2237 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2238 functions directly instead of trying to detect at runtime that our
2239 host operating system supports them. We make this change for two
2240 reasons: Cygwin lacks support for the multibyte character
2241 conversion functions used by the legacy menu code, and Cygwin
2242 never needs to rely on non-Unicode APIs.
2244 * unexw32.c (hinst): Declare extern.
2246 * w32.c: Change header order;
2247 (w32_strerror): Move to w32fns.c because we need it for
2248 non-WINDOWSNT builds.
2250 * w32.h: Add #error macro to make sure we don't include w32.h for
2251 Cygwin builds. Remove w32select declarations.
2253 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2254 w32fns.c. w32console.c is WINDOWSNT-only.
2256 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2257 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2259 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2260 (w32_major_version, w32_minor_version, w32_build_number)
2261 (os_subtype, sound_type): Define here
2262 (w32_defined_color): Make color parameter const for consistency
2263 with other _defined_color functions.
2264 (w32_createwindow): Unconditionally call w32_init_class instead of
2265 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2266 through the code is complex and unnecessary because class
2267 registration is practically free.
2268 (w32_name_of_message): New EMACSDEBUG-only function.
2269 (Fset_message_beep): Move here
2270 (Fx_open_connection): Require that the display name for Windows be
2271 "w32" for consistency, emacsclient disambiguation, and maybe, one
2272 day, multi-window-system support.
2273 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2274 Cygwin files for W32 GUI facilities, since these clearly don't
2275 expect Cygwin names.
2276 (_DebPrint): Define.
2277 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2278 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2279 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2280 (w32_last_error): Remove.
2282 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2284 * w32heap.c (syspage_mask): Declare here.
2285 (cache_system_info): Remove.
2287 * w32inevt.c (faked_key): Define globally, not statically.
2288 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2289 (w32_console_toggle_lock_key): Move to w32fns.c.
2291 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2293 * w32proc.c (_DebPrint): Move to w32fns.c.
2294 * w32select.c: Include string.h, stdio.h for Cygwin.
2295 * w32select.h: New File.
2297 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2299 (w32_message_fd): New variable. Under Cygwin, holds the file
2300 descriptor the system used to tell us about pending thread
2303 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2304 that prevented compilation under non-WINDOWSNT systems.
2306 (w32_initialize): Open /dev/windows and assign it to
2307 w32_message_fd. Provide w32 feature.
2309 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2310 (WM_EMACS_INPUT_READY): add.
2311 (prepend_msg, w32_message_fd): Declare globally.
2314 (keyboard_handle): Use only when WINDOWSNT.
2315 (notify_msg_ready): New function. Posts a message to the main
2316 thread's message queue under CYGWIN, which wakes up the main
2317 thread from select(2) by making the /dev/windows file descriptor
2318 ready. Under WINDOWSNT, it sets an event the same way the old
2321 (post, prepend_msg): Actually call notify_msg_ready instead of
2322 setting the input event directly.
2324 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2326 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2327 but it still has blocs in it, don't return it to the system,
2328 instead of aborting. (Bug#12402)
2330 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2332 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2334 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2335 MAC_OS_X_VERSION_10_6.

2338 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2339 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2340 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2342 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2343 MAC_OS_X_VERSION_10_4.
2345 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2346 MAC_OS_X_VERSION_10_2.
2348 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2350 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2351 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2353 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2354 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2355 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):

2367 defined as a macro, as is done in Solaris.
2368 (sys_siglist_entries): New macro.
2369 (save_strsignal): Use it.
2370 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2371 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2373 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2375 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2376 fullscreen/Fullscreen.
2378 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2379 tobar_height is new.
2381 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2382 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2383 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2384 (windowDidResize:): Check for correct window if old style fullscreen.
2385 Capitalize word in comment. Remove incorrect comment.
2386 (initFrameFromEmacs:): tbar_height renamed tibar_height.

2398 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2400 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2402 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2403 that time stamps of directories could also be changed.
2404 Don't request the too broad GENERIC_WRITE, only the more restrictive
2405 FILE_WRITE_ATTRIBUTES access rights.
2407 * fileio.c (Fset_file_times): Special-case ignoring errors for
2408 directories only on MSDOS, not on MS-Windows.
2410 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2412 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2414 2012-10-04 Eli Zaretskii <eliz@gnu.org>

2417 see whether CreateFile failed.
2419 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2421 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2422 to avoid similar races.
2423 * keyboard.c (pending_signals): Now bool, not int.
2425 Port timers to OpenBSD, plus check for timer failures.
2426 OpenBSD problem reported by Han Boetes.
2427 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2429 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2430 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2431 like OpenBSD, which has timer_settime but does not declare it.
2432 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2433 whether to use itimerspec-related primitives. All uses of
2434 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2436 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2438 * profiler.c (handle_profiler_signal): Fix a malloc race
2439 that caused Emacs to hang on Fedora 17 when profiling Lisp.

2443 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2445 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2447 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2448 consistent with the change in return value of 'safe_strsignal'.
2450 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2452 Prefer plain 'static' to 'static inline' (Bug#12541).
2453 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2454 (bidi_set_sor_type, bidi_push_embedding_level)
2455 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

2460 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2461 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2462 Now 'static', not 'static inline'.
2464 Count overruns when profiling; change units to ns.
2465 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2466 Give extra weight to samples after overruns, to attempt to count
2467 the time more accurately.
2468 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2469 the underlying primitives nominally do ns.
2470 (Fprofiler_cpu_start): Document the change. Mention that
2471 the sampling intervals are only approximate.
2473 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2475 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2477 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2478 case for the special 0 coding-system.
2480 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2481 (Fmake_overlay): Remove redundant tests.
2482 (fix_start_end_in_overlays): Remove redundant recentering.
2484 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2486 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2487 Update dependencies.
2489 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2491 Fix a malloc race condition involving strsignal.
2492 A signal can arrive in the middle of a malloc, and Emacs's signal
2493 handler can invoke strsignal, which can invoke malloc, which is
2494 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2495 Fix it by altering the signal handler so that it does not invoke
2497 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2498 * process.c (status_message): Use const pointer, in case strsignal
2499 is #defined to safe_strsignal.
2500 * sysdep.c (sys_siglist, init_signals): Always define and
2501 initialize a substitute sys_siglist if the system does not define
2502 one, even if HAVE_STRSIGNAL.
2503 (safe_strsignal): Rename from strsignal. Always define,
2504 using sys_siglist. Return a const pointer.
2505 * syssignal.h (safe_strsignal): New decl.
2506 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2508 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2510 * w32proc.c (timer_loop): Fix code that waits for timer
2511 expiration, to avoid high CPU usage.
2513 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2515 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2516 (sweep_weak_table): Remove redundant prototypes.
2518 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2520 * emacs.c: Move the inclusion of TERM_HEADER after including
2521 windows.h on WINDOWSNT. This avoids compilation problems with
2524 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2526 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2527 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2528 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2529 as the previous version used 'void *'.
2531 * ralloc.c (ROUNDUP): Fix last change.
2532 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2535 * w32proc.c <disable_itimers>: New static flag.
2536 (init_timers): Initialize it to zero, after creating the critical
2537 sections used by the timer threads.
2538 (term_timers): Set to 1 before deleting the critical sections.
2539 (getitimer, setitimer): If disable_itimers is non-zero, return an
2540 error indication without doing anything. Reported by Fabrice
2541 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2542 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2544 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2547 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2548 term_ntproc after all the other bookkeeping, to get timers working
2549 as long as possible.
2551 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2553 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2554 Suggested by Juri Linkov in
2555 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2557 Prefer plain 'static' to 'static inline' (Bug#12541).
2558 With static functions, modern compilers inline pretty well by
2559 themselves; advice from programmers often hurts as much as it helps.
2560 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2561 this change shrinks the text size of the Emacs executable by 1.1%
2562 without affecting CPU significantly in my benchmark.
2563 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2643 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2645 Revert the FOLLOW-SYMLINKS change for file-attributes.
2646 Doing it right would require several changes to Tramp, and there's
2647 not enough time to get that tested before the freeze today.
2648 * dired.c (directory_files_internal, Ffile_attributes):
2651 * frame.c (x_report_frame_params): Port better to wider ints.
2652 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2653 or that pointers can be printed in 15 decimal digits.
2654 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2772 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
2774 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
2776 * w32.h (init_timers, term_timers): Add prototypes.
2778 2012-09-30 Kenichi Handa <handa@gnu.org>
2780 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
2781 to the buffer relocation which may be caused by ccl_driver.

2812 fullscreen. Set maximized_width/height. Act on next_maximized.
2814 * nsterm.h (MAC_OS_X_VERSION_10_7, MAC_OS_X_VERSION_10_8): New.
2815 (EmacsView): Add variables for fullscreen.
2816 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
2817 (EmacsFSWindow): New interface for fullscreen.
2819 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
2821 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
2823 2012-09-30 Chong Yidong <cyd@gnu.org>
2825 * fns.c (Frandom): Doc fix.
2827 2012-09-30 Martin Rudalics <rudalics@gmx.at>
2829 * window.c (Vwindow_combination_limit): New default value.
2830 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
2832 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2834 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
2835 Suggested by Eli Zaretskii in
2836 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2838 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2840 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2841 HAVE_TIMER_SETTIME is defined.
2843 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2845 Profiler improvements: more-accurate timers, overflow checks.
2846 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2847 signal.h, setjmp.h. Include systime.h instead.
2848 (saturated_add): New function.
2849 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
2850 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
2851 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
2853 (enum profiler_cpu_running): New enum.
2854 (profiler_cpu_running): Now of that enum type, not bool.
2855 All uses changed to store the new value.
2856 (handle_profiler_signal): Rename from sigprof_handler_1,
2857 for consistency with other handlers. Do not check whether
2858 cpu_log is a hash-table if garbage collecting, since it
2859 doesn't matter in that case.
2860 (deliver_profiler_signal): Rename from sigprof_handler,
2861 for consistency with other handlers.
2862 (setup_cpu_timer): New function, with much of what used to be in
2863 Fprofiler_cpu_start. Check for out-of-range argument.
2864 Prefer timer_settime if available, and prefer
2865 thread cputime clocks, then process cputime clocks, then
2866 monotonic clocks, to the old realtime clock. Use make_timeval
2867 to round more-correctly when falling back to setitimer.
2868 (Fprofiler_cpu_start): Use it.
2869 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2870 Don't assume that passing NULL as the 2nd argument of setitimer
2871 is the same as passing a pointer to all-zero storage.
2872 Ignore SIGPROF afterwards.
2873 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2874 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2875 non-fatal signal handlers. Ignore SIGPROF on startup.
2876 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2877 in profiler.c, since sysdep.c now uses it.
2879 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
2880 Suggested by Eli Zaretskii in
2881 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2931 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
2933 * character.h (MAYBE_UNIFY_CHAR): Remove.
2934 * charset.c, charset.h (maybe_unify_char): Now static.
2935 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2936 Since this stuff is now private to charset.c, there's no need for
2937 a public macro and no need to inline by hand.
2939 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
2940 Stefan Monnier <monnier@iro.umontreal.ca>

2970 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
2972 Prefer POSIX timers if available.
2973 They avoid a race if the timer is too close to the current time.
2974 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
2975 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

2978 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2980 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
2981 CHAR_STRING_ADVANCE.
2982 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
2983 STRING_CHAR_ADVANCE.

2999 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
3001 * w32.h (Vlibrary_cache): Do not declare.
3003 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3005 * w32proc.c (sys_signal): Handle all signals defined by the
3006 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3007 handlers for signals supported by Windows. Don't override
3008 term_ntproc as the handler for SIGABRT.
3009 (sigaction): Rewrite to call sys_signal instead of duplicating its
3011 (sys_kill): Improve commentary.
3013 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3014 consistency with a signature of a signal handler. All callers
3016 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3017 install term_ntproc as a signal handler for SIGABRT, as that
3018 should be done by the dumped Emacs.
3020 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3022 * w32select.c (term_w32select): Protect against repeated
3023 invocation by setting clipboard_owner to NULL after calling
3026 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3027 and term_ntproc to their modified signatures.
3029 * character.c (char_string, string_char): Remove calls to
3030 MAYBE_UNIFY_CHAR. See the discussion starting at

3034 2012-09-25 Chong Yidong <cyd@gnu.org>
3036 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
3038 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3040 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3041 when encountering an unknown bytecode.
3043 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3045 image.c, indent.c: Use bool for booleans.
3046 * dispextern.h (struct image_type): Members valid_p, load, init

3048 * image.c: Omit unnecessary static decls.
3049 (x_create_bitmap_mask, x_build_heuristic_mask):

3087 Move pid_t related decls out of lisp.h.
3088 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3089 (interruptible_wait_for_termination):
3090 Move these decls from lisp.h to syswait.h, since they use pid_t.
3091 Needed on FreeBSD; see Herbert J. Skuhra in
3092 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3093 * callproc.c: Include syswait.h.

3139 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3141 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3142 fatal_error_backtrace.
3144 * w32proc.c (sys_kill): Undo last change: don't do anything when
3145 invoked to deliver SIGABRT to our own process. This is now
3146 handled by emacs_raise.
3148 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3150 * w32term.c (w32_read_socket): Remove leftover reference to
3151 interrupt_input_pending.
3153 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3155 Do not use SA_NODEFER.
3156 Problem reported by Dani Moncayo in
3157 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3159 * sysdep.c (emacs_abort): Do not reset signal handler.
3160 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3161 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3162 wanted even on POSIXish hosts, and it doesn't work on Windows.
3164 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3166 * xterm.c (x_term_init): Call fixup_locale before and after calling
3167 gtk_init (Bug#12392).
3169 2012-09-23 Chong Yidong <cyd@gnu.org>
3171 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3172 Vdynamic_library_alist.
3174 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3175 (Fgnutls_available_p): Caller changed.
3177 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3178 (Flibxml_parse_xml_region): Likewise.
3180 * dispextern.h (struct image_type): Remove arg from init function.
3182 * image.c (Finit_image_library, lookup_image_type)
3183 (define_image_type): Remove now-unneeded second arg.
3184 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3185 (init_tiff_functions, init_gif_functions, init_svg_functions):
3186 Arglist and w32_delayed_load calling convention changed.
3187 (gs_type): Remove init_gs_functions; there is no such function.
3188 (valid_image_p, make_image): Fix caller to lookup_image_type.
3190 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3192 Simplify and avoid signal-handling races (Bug#12471).
3194 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3195 Avoid recursive loop if there's a fatal error in the function itself.
3196 * atimer.c (pending_atimers):
3197 * blockinput.h: Don't include "atimer.h"; no longer needed.
3198 (interrupt_input_pending): Remove. All uses removed.
3199 pending_signals now counts both atimers and ordinary interrupts.
3200 This is less racy than having three separate pending-signal flags.
3201 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3203 Rename from their upper-case counterparts BLOCK_INPUT,
3204 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3205 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3206 This makes it easier to access volatile variables more accurately.
3207 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3208 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3209 that's more reliable if the code is buggy and sets
3210 interrupt_input_blocked to a negative value. All uses changed.
3211 * atimer.c (deliver_alarm_signal):
3212 Remove. No need to deliver this to the parent; any thread can
3213 handle this signal now. All uses replaced by underlying handler.
3214 * atimer.c (turn_on_atimers):
3215 * dispnew.c (handle_window_change_signal):
3216 * emacs.c (handle_danger_signal):
3217 * keyboard.c (kbd_buffer_get_event):
3218 Don't reestablish signal handler; not needed with sigaction.
3219 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3221 Rework to avoid unnecessary accesses to volatile variables.
3222 (UNBLOCK_INPUT_TO): Now a function.
3223 (totally_unblock_input, unblock_input): New decls.
3224 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3225 (init_data): Remove. Necessary stuff now done in init_signal.
3226 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3227 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3228 (fatal_error_code): Remove; no longer needed.
3229 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3230 it doesn't always backtrace. All uses changed. No need to reset
3231 signal to default, since sigaction and/or die does that for us now.
3232 Use emacs_raise (FOO), not kill (getpid (), FOO).
3233 (main): Check more-accurately whether we're dumping.
3234 Move fatal-error setup to sysdep.c
3235 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3236 * gtkutil.c (xg_get_file_name, xg_get_font):
3237 Remove no-longer-needed signal-mask manipulation.
3238 * keyboard.c, process.c (POLL_FOR_INPUT):
3239 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3240 * keyboard.c (read_avail_input): Remove.
3241 All uses replaced by gobble_input.
3242 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3243 (kbd_buffer_store_event_hold, gobble_input):
3244 (record_asynch_buffer_change) [USABLE_SIGIO]:
3245 (store_user_signal_events):
3246 No need to mess with signal mask.
3247 (gobble_input): If blocking input and there are terminals, simply
3248 set pending_signals to 1 and return. All hooks changed to not
3249 worry about whether input is blocked.
3250 (process_pending_signals): Clear pending_signals before processing
3251 them, in case a signal comes in while we're processing.
3252 By convention callers now test pending_signals before calling us.
3253 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3254 New functions, to support changes to blockinput.h.
3255 (handle_input_available_signal): Now extern.
3256 (reinvoke_input_signal): Remove. All uses replaced by
3258 (quit_count): Now volatile, since a signal handler uses it.
3259 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3260 All callers changed. Block SIGINT only if not already blocked.
3261 Clear sigmask reliably, even if Fsignal returns, which it can.
3262 Omit unnecessary accesses to volatile var.
3263 (quit_throw_to_read_char): No need to restore sigmask.
3264 * keyboard.c (gobble_input, handle_user_signal):
3265 * process.c (wait_reading_process_output):
3266 Call signal-handling code rather than killing ourselves.
3267 * lisp.h: Include <float.h>, for...
3268 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3269 (pending_signals): Now volatile.
3270 (syms_of_data): Now const if IEEE floating point.
3271 (handle_input_available_signal) [USABLE_SIGIO]:
3272 (terminate_due_to_signal, record_child_status_change): New decls.
3273 * process.c (create_process): Avoid disaster if memory is exhausted
3274 while we're processing a vfork, by tightening the critical section
3276 (send_process_frame, process_sent_to, handle_pipe_signal)
3277 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3279 (send_process): No need for setjmp/longjmp any more, since the
3280 SIGPIPE stuff is now gone. Instead, report an error if errno
3282 (record_child_status_change): Now extern. PID and W are now args.
3283 Return void, not bool. All callers changed.
3284 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3285 Remove. All uses removed. This bug should be fixed now in a
3287 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3288 and record the child status change directly. This avoids the
3289 need to futz with the signal mask.
3290 (process_fatal_action): Move here from emacs.c.
3291 (emacs_sigaction_flags): New function, containing
3292 much of what used to be in emacs_sigaction_init.
3293 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3294 caught by emacs, to make races less likely.
3295 (deliver_process_signal): Rename from handle_on_main_thread.
3297 (BACKTRACE_LIMIT_MAX): Now at top level.
3298 (thread_backtrace_buffer, threadback_backtrace_pointers):
3300 (deliver_thread_signal, deliver_fatal_thread_signal):
3301 New functions, for more-accurate delivery of thread-specific signals.
3302 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3303 (deliver_arith_signal): Handle in this thread, not
3304 in the main thread, since it's triggered by this thread.
3305 (maybe_fatal_sig): New function.
3306 (init_signals): New arg DUMPING so that we can be more accurate
3307 about whether we're dumping. Caller changed.
3308 Treat thread-specific signals differently from process-general signals.
3309 Block all signals while handling fatal error; that's safer.
3310 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3312 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3313 Ignore SIGPIPE unless batch.
3314 (emacs_backtrace): Output backtrace for the appropriate thread,
3315 which is not necessarily the main thread.
3316 * syssignal.h: Include <stdbool.h>.
3317 (emacs_raise): New macro.
3318 * xterm.c (x_connection_signal): Remove; no longer needed
3319 now that we use sigaction.
3320 (x_connection_closed): No need to mess with sigmask now.
3321 (x_initialize): No need to reset SIGPIPE handler here, since
3322 init_signals does this for us now.
3324 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3326 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3327 background rect may be larger (Bug#12245).
3329 2012-09-23 Chong Yidong <cyd@gnu.org>
3331 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3333 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3335 * .gdbinit: Just stop at fatal_error_backtrace.
3336 See Stefan Monnier's request in
3337 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3338 Remove no-longer-used query of system type.
3340 2012-09-22 Chong Yidong <cyd@gnu.org>
3342 * search.c (Freplace_match): Doc fix (Bug#12325).
3344 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3346 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3347 (Fline_end_position): Doc fix.
3349 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3351 2012-09-22 Chong Yidong <cyd@gnu.org>
3353 * dispextern.h (struct image_type): Add new slot, storing a type
3354 initialization function.
3356 * image.c (define_image_type): Call the image initializer function
3357 if it is defined. Arguments and return value changed.
3358 (valid_image_p, make_image): Callers changed.
3359 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3360 (gif_type, imagemagick_type, svg_type, gs_type):
3361 Add initialization functions.
3362 (Finit_image_library): Call lookup_image_type.
3363 (CHECK_LIB_AVAILABLE): Macro deleted.
3364 (lookup_image_type): Call define_image_type here, rather than via
3365 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3366 (syms_of_image): Move define_image_type calls for xbm_type and
3367 pbm_type to lookup_image_type.
3369 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3371 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3372 'idle_timers' from here ...
3373 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3374 lists, to avoid infloops when the timer does something stupid,
3375 like reinvoke itself with the same or smaller time-out.
3378 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3380 * window.c (Fsplit_window_internal): Handle only Qt value of
3381 Vwindow_combination_limit separately.
3382 (Qtemp_buffer_resize): New symbol.
3383 (Vwindow_combination_limit): New default value.
3386 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3388 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3389 the new overlay string. (Bug#10159)
3391 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3393 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3394 or that fprintf is async-signal-safe. POSIX doesn't require
3397 2012-09-22 Chong Yidong <cyd@gnu.org>
3399 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3402 2012-09-22 Kenichi Handa <handa@gnu.org>
3404 * composite.c (composition_reseat_it): Handle the case that a
3405 grapheme cluster is not covered by a single font (Bug#12352).
3407 2012-09-21 Chong Yidong <cyd@gnu.org>
3409 * image.c (define_image_type): Avoid adding duplicate types to
3410 image_types (Bug#12463). Suggested by Jörg Walter.
3412 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3414 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3415 (print_load_command_name): Add case LC_DATA_IN_CODE.
3416 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3418 2012-09-21 Glenn Morris <rgm@gnu.org>
3420 * eval.c (Frun_hook_with_args_until_success)
3421 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3423 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3425 * fileio.c (Ffile_selinux_context): Only call freecon when
3426 lgetfilecon succeeded.
3427 (Fset_file_selinux_context): Likewise. (Bug#12444)
3429 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3431 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3432 reordering, locate the cursor by calling set_cursor_from_row; if
3433 that fails, clear the desired glyph matrix before returning a
3434 failure indication to the caller. Fixes leaving garbled display
3435 when fast scrolling with a down-key. (Bug#12403)
3436 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3437 scrolling through multibyte text.
3439 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3441 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3442 calling mark_vectorlike since that's the one that marks the window.
3443 (mark_discard_killed_buffers): Mark the final cdr.
3444 * window.h (struct window): Move prev/next_buffers to the
3445 non-standard fields.
3446 * window.c (make_window): Initialize prev/next_buffers manually.
3448 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3450 Omit unused arg EXPECTED from socket hooks.
3451 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3452 * nsterm.m (ns_term_init):
3453 * termhooks.h (struct terminal.read_socket_hook):
3454 * w32inevt.c (w32_console_read_socket):
3455 * w32term.c (w32_read_socket):
3456 * xterm.c (XTread_socket):
3457 Omit unused arg EXPECTED. All callers changed.
3458 (store_user_signal_events): Return void, not int, since callers no
3459 longer care about the return value. All uses changed.
3461 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3463 * w32gui.h (XParseGeometry): Do not declare.
3465 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3467 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3468 Ignore 'expected'. See Eli Zaretskii in
3469 <http://bugs.gnu.org/12471#8> (last line).
3471 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3472 (XParseGeometry): Now static. Substitute extremal values for
3473 values that are out of range.
3475 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3477 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3479 * nsfns.m (XParseGeometry): Remove.
3480 (Fx_create_frame): Call x_set_offset to correctly interpret
3481 top_pos in geometry.
3483 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3484 (Fx_parse_geometry): If there is a space in string, call
3485 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3487 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3489 * search.c (scan_buffer): Use character positions in calls to
3490 region_cache_forward and region_cache_backward, not byte
3491 positions. (Bug#12196)
3493 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3494 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3496 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3497 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3498 emacs_blocked_malloc, now deleted.
3500 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3502 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3503 The workaround was for improving performance on Solaris 2.4, but
3504 is getting in the way now. Emacs will still work if someone is
3505 still running Solaris 2.4 in a museum somewhere; Sun dropped
3506 support for Solaris 2.4 in 2003.
3507 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3508 * process.c (create_process) [HAVE_WORKING_VFORK]:
3509 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3510 since Emacs no longer uses vfork on that platform.
3512 2012-09-17 Glenn Morris <rgm@gnu.org>
3514 * emacs.c: Use COPYRIGHT.
3516 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3518 Remove configure's --without-sync-input option (Bug#12450).
3519 When auditing signal-handling in preparation for cleaning it up,
3520 I found that SYNC_INPUT has race conditions and would be a real
3521 pain to fix. Since it's an undocumented and deprecated
3522 configure-time option, now seems like a good time to remove it.
3523 Also see <http://bugs.gnu.org/11080#16>.
3524 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3525 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3526 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3527 (malloc_hysteresis):
3528 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3529 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3530 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3531 (dont_register_blocks, bytes_used_when_reconsidered)
3532 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3533 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3534 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3535 Remove. All uses removed.
3536 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3537 implementation, one that depends on whether the new macro
3538 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3540 * atimer.c (run_timers, handle_alarm_signal):
3541 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3542 (handle_async_input, process_pending_signals)
3543 (handle_input_available_signal, init_keyboard):
3544 * nsterm.m (ns_read_socket):
3545 * process.c (wait_reading_process_output):
3546 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3547 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3549 * xterm.c (XTread_socket):
3551 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3552 * eval.c (handling_signal): Remove. All uses removed.
3553 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3554 All uses replaced with the SYNC_INPUT version.
3555 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3557 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3560 * font.c (Ffont_shape_gstring): Remove unused local.
3562 2012-09-16 Glenn Morris <rgm@gnu.org>
3564 * Makefile.in (clean): No longer run nextstep's clean.
3566 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3568 (ns-app): Move here from ns.mk, and simplify.
3569 (clean): Simplify nextstep entry.
3570 * ns.mk: Remove file.
3572 2012-09-17 Kenichi Handa <handa@gnu.org>
3574 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3575 not covert the last few charactes.
3577 2012-09-16 Kenichi Handa <handa@gnu.org>
3579 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3580 here, but just check the validity of glyphs in the glyph-string.
3582 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3584 * window.c (Fwindow_parameter, Fset_window_parameter):
3585 Accept any window as argument (Bug#12452).
3587 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3589 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3590 to ns_term_init to avoid memory leak.
3592 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3593 explicit retain/release.
3594 (ns_term_init): Only allow one display. Initialize outerpool and
3597 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3599 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3600 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3601 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3602 the Microsoft problem in a different way, by altering ../nt/config.nt.
3604 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3619 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3620 by lisp.h. This completes removal of setjmp.h inclusion
3621 erroneously announced in the previous commit. (Bug#12446)
3623 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3626 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3627 not defined as a macro. The latter happens on MS-Windows.
3630 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3632 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3633 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3634 Some instances of '#include <setjmp.h>' removed, if the
3635 only reason for the instance was because "lisp.h" was included.
3636 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3637 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3638 and _longjmp with the new symbols. Emacs already uses _setjmp if
3639 available, so this change affects only POSIXish hosts that have
3640 sigsetjmp but not _setjmp, such as some versions of Solaris and
3641 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3642 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3643 (png_load_body) [HAVE_PNG]:
3644 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3645 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3646 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3647 since PNG requires jmp_buf. This is the only exception to the
3648 general rule that we now use sys_setjmp and sys_longjmp.
3649 This exception is OK since this code does not change the signal
3650 mask or longjmp out of a signal handler.
3652 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3654 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3655 Include "syssignal.h", for 'main_thread'.
3657 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3659 Avoid out-of-range marker position (Bug#12426).
3660 * insdel.c (replace_range, replace_range_2):
3661 Adjust markers before overlays, as suggested by comments.
3662 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3663 Remove redundant check before calling offset_intervals.
3665 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3667 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3668 current buffer (Bug#12387).
3670 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3672 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3674 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3676 Use a more backwards-compatible timer format (Bug#12430).
3677 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3678 vector element, not from the 4th, since PSECS is now at the end.
3679 (Fcurrent_idle_time): Doc fix.
3681 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3683 Function to mark objects and remove killed buffers at once.
3684 * alloc.c (discard_killed_buffers): Rename to ...
3685 (mark_discard_killed buffers) ... new name. Add marking
3686 of remaining objects. Fix comment. Adjust users.
3687 (mark_object): Do not touch frame buffer lists here.
3688 * frame.c (delete_frame): Reset frame buffer lists here.
3690 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3692 Better workaround for GNOME bug when --enable-gcc-warnings.
3693 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3694 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3695 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3697 Simplify SIGIO usage (Bug#12408).
3698 The code that dealt with SIGIO was crufty and confusing, e.g., it
3699 played tricks like "#undef SIGIO" but these tricks were not used
3700 consistently. Simplify mostly by not #undeffing standard symbols,
3701 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3702 or not as we please) rather than "defined SIGIO" (standard symbol
3703 that we probably shouldn't #undef).
3704 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3705 Modules that need it can include it.
3706 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3707 * dispextern.h (ignore_sigio): New decl.
3708 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3709 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3710 * emacs.c (shut_down_emacs):
3711 * keyboard.c (kbd_buffer_store_event_hold):
3712 Use ignore_sigio rather than invoking 'signal' directly.
3713 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3715 (FIONREAD, SIGIO): Do not #undef.
3716 (tty_read_avail_input): Use #error rather than a syntax error.
3717 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3718 for I_PIPE, used by SETUP_SLAVE_PTY.
3719 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3720 * sysdep.c (croak): Remove; no longer needed. This bit of
3721 temporary code, with Fred N. Fish's comment that it's temporary,
3722 has been in Emacs since at least 1992!
3723 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3724 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3725 * syssignal.h (croak): Remove decl.
3726 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3727 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3728 now that we're termios-only.
3729 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3730 * term.c (dissociate_if_controlling_tty): Use #error rather than
3733 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3734 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3735 to work around GNOME bug 683906.
3736 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3737 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3738 This works around GCC bug 54561.
3740 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3742 More fixes for 'volatile' and setjmp/longjmp.
3743 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3744 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3745 (png_load_body) [HAVE_PNG]:
3746 (jpeg_load_body) [HAVE_JPEG]:
3747 New function, with most of the old parent function's body.
3748 (png_load) [HAVE_PNG]:
3749 (jpeg_load) [HAVE_JPEG]:
3750 Invoke the new function, to avoid longjmp munging our locals.
3751 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3752 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3753 longjmp is passed 2, as the C standard doesn't guarantee this.
3754 Instead, store the failure code into mgr->failure_code.
3756 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3758 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3759 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3760 (syms_of_keyboard): Remove support for unread-command-char.
3762 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3764 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3765 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3766 violation. (Bug#12426)
3768 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3770 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3772 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3774 * eval.c: Add `inhibit-debugger'.
3775 (Qinhibit_debugger): New symbol.
3776 (call_debugger): Bind it instead of Qdebug_on_error.
3777 (maybe_call_debugger): Test Vinhibit_debugger.
3778 (syms_of_eval): Define inhibit-debugger.
3779 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3780 (syms_of_xdisp): Remove inhibit-debug-on-message.
3782 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3784 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3785 If a nonvolatile local variable is written before a _longjmp to
3786 the frame containing the variable, and is read after the _longjmp,
3787 the value read is indeterminate. Some local variables of type
3788 'struct handler' and 'struct catchtag' are used in this way, so
3789 mark each of their slots as volatile if the slot can be set before
3790 _longjmp and read afterwards.
3791 * lisp.h (struct handler): var and chosen_clause are now volatile.
3792 (struct catchtag): val, next, and pdlcount are now volatile.
3794 * bidi.c (bidi_push_it, bidi_pop_it):
3795 * fns.c (copy_hash_table):
3796 * image.c (define_image_type):
3797 * keyboard.c (kbd_buffer_store_event_hold):
3798 * process.c (Fprocess_send_eof):
3799 * xfaces.c (x_create_gc) [HAVE_NS]:
3800 * xgselect.c (xg_select):
3801 Prefer assignment to memcpy when either will do.
3803 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3804 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3805 time an item is removed. No need to mark this function 'inline';
3806 the compiler knows better than we do.
3808 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3810 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3811 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3812 to change_frame_size (Bug#12388).
3813 (windowDidResize:): Pass YES to updateFrameSize.
3815 * nsterm.h: Add delay parameter to updateFrameSize.
3817 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3819 Discard killed buffers from deleted window and frame objects.
3820 This reduces an amount of references to killed buffers and
3821 helps GC to reclaim them faster.
3822 * alloc.c (discard_killed_buffers): New function.
3823 (mark_object): Use it for deleted windows and frames.
3824 (mark_object): If symbol's value is set up for a killed buffer
3825 or deleted frame, restore its global binding.
3826 * data.c (swap_in_global_binding): Add GC notice.
3827 (swap_in_symval_forwarding): Use convenient set_blv_where.
3828 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3829 * window.h: ... to here.
3831 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3833 Convenient macro to check whether the buffer is live.
3834 * buffer.h (BUFFER_LIVE_P): New macro.
3835 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3836 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3838 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3840 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3841 composition cases (Bug#12364).
3843 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3844 overhang of succeeding glyphs overlapping box cursor.
3846 * w32term.c (x_draw_glyph_string): Likewise.
3848 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3850 Simplify, document, and port floating-point (Bug#12381).
3851 The porting part of this patch fixes bugs on non-IEEE platforms
3852 with frexp, ldexp, logb.
3853 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3855 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3856 support, by removing commented-out code and briefly listing the
3857 C89 functions excluded. The commented-out stuff was confusing
3858 maintenance, e.g., we thought we needed cbrt but it was commented out.
3859 (logb): Remove decl; no longer needed.
3860 (isfinite): New macro, if not already supplied.
3861 (isnan): Don't replace any existing macro.
3862 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3863 are present on all C89 platforms.
3864 (Ffrexp): Do not special-case zero, as frexp does the right thing
3866 (Flogb): Do not use logb, as it doesn't have the desired meaning
3867 on hosts that use non-base-2 floating point. Instead, stick with
3868 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3869 frexp, to avoid getting an unspecified result.
3871 * xdisp.c (Qinhibit_debug_on_message): Now static.
3873 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3875 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3876 NSBezierPath (Bug#12131).
3878 2012-09-10 Chong Yidong <cyd@gnu.org>
3880 * fns.c (Fdelq, Fdelete): Doc fix.
3882 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3884 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3885 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3887 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3889 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3890 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3893 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3895 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3896 left fringe if the window has a left margin. This avoids leaving
3897 traces of the cursor because its leftmost pixel is not drawn over.
3899 * dispnew.c (update_window_line): When the left margin area of a
3900 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3901 that screen line. (Bug#12277)
3903 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3905 Assume C89 or later for math functions (Bug#12381).
3906 This simplifies the code, and makes it a bit smaller and faster,
3907 and (most important) makes it easier to clean up signal handling
3908 since we can stop worring about floating-point exceptions in
3909 library code. That was a problem before C89, but the problem
3910 went away many years ago on all practical Emacs targets.
3911 * data.c, image.c, lread.c, print.c:
3912 Don't include <math.h>; no longer needed.
3913 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3914 might be autoconfigured, as that never happens.
3916 * doprnt.c (DBL_MAX_10_EXP):
3917 * print.c (DBL_DIG):
3918 Remove. C89 or later always defines these.
3919 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3920 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3921 (arith_error, domain_error, domain_error2):
3922 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3923 no longer needed -- we simply return what C returns. All uses removed.
3924 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3926 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3927 Remove. All uses expanded, as these macros are no longer used
3928 more than once and are now more trouble than they're worth.
3929 (Ftan): Use tan, not sin / cos.
3930 (Flogb): Assume C89 frexp.
3931 (fmod_float): Assume C89 fmod.
3932 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3933 (init_floatfns): Remove. All uses removed.
3935 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3937 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3938 compositeToPoint for OSX < 10.6 (Bug#12390).
3940 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3942 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3943 This produces more-accurate results.
3945 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3947 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3948 changes (Bug#12088).
3950 2012-09-08 Chong Yidong <cyd@gnu.org>
3952 * syntax.c (Fstring_to_syntax): Doc fix.
3954 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3956 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3957 in the internal border.
3958 (x_set_window_size): Remove static variables and their usage.
3959 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3960 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3961 Remove fringe/internal border adjustment (Bug#11052).
3962 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3963 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3964 (ns_fix_rect_ibw): Remove.
3965 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3966 (ns_dumpglyphs_box_or_relief): Ditto.
3967 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3969 (ns_dumpglyphs_image): Ditto.
3970 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3972 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3973 their usage. Add fringe_extended_p and its use as in other terms.
3974 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3975 scroll bar was removed.
3976 (updateFrameSize): New function.
3977 (windowDidResize): Move code to updateFrameSize and call it.
3979 * nsterm.h (EmacsView): Add updateFrameSize.
3981 2012-09-07 Chong Yidong <cyd@gnu.org>
3983 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3985 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3987 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3989 More signal-handler cleanup (Bug#12327).
3990 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3991 Problem introduced when merging patches. Noted by Eli Zaretskii in
3992 <http://bugs.gnu.org/12327#67>.
3993 * floatfns.c: Comment fix.
3994 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3995 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3996 and anyway the declaration is harmless even if SIGDANGER is not defined.
3997 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3998 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3999 source files not surprisingly expected syssignal.h to define, or
4000 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4001 Include <sys/ioctl.h>, for FIONREAD.
4002 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4003 This eliminates a problem whereby other files mysteriously had
4004 to include "syssignal.h" before including "systty.h" if they
4005 wanted to use "#ifdef SIGIO".
4007 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4009 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4011 * w32.c (sigemptyset): Empty the set.
4012 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4014 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4016 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4018 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4019 (mark_object): Likewise for frame objects.
4021 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4023 * syssignal.h (handle_on_main_thread): Always declare,
4024 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4025 This ports to platforms without HAVE_PTHREAD.
4027 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4029 Signal-handler cleanup (Bug#12327).
4030 Emacs's signal handlers were written in the old 4.2BSD style with
4031 sigblock and sigmask and so forth, and this led to some
4032 inefficiencies and confusion. Rewrite these to use
4033 pthread_sigmask etc. without copying signal sets around. Also,
4034 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4035 'signal', and instead use functions that do not attempt to take
4036 over the system name space. This patch causes Emacs's text
4037 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4038 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4039 Do not include <signal.h> or "syssignal.h", as these
4040 modules do not use signals.
4041 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4042 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4043 Do not include <signal.h>, as "syssignal.h" does that for us now.
4044 * atimer.c (sigmask_atimers): New function.
4045 (block_atimers, unblock_atimers): New functions,
4046 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4048 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4049 no longer needed here.
4050 * emacs.c (main): Inspect existing signal handler with sigaction,
4051 so that there's no need to block and unblock SIGHUP.
4052 * sysdep.c (struct save_signal): New member 'action', replacing
4053 old member 'handler'.
4054 (save_signal_handlers, restore_signal_handlers):
4055 Use sigaction instead of 'signal' to save and restore.
4056 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4057 New function. All users of 'signal' modified to use set_sighandler
4058 if they're writeonly, and to use sys_signal if they're read+write.
4059 (emacs_sigaction_init, forwarded_signal): New functions.
4060 (sys_signal): Remove. All uses replaced by calls to sigaction
4061 and emacs_sigaction_init, or by direct calls to 'signal'.
4062 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4063 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4064 all uses replaced by pthread_sigmask etc. calls.
4065 * syssignal.h: Include <signal.h>.
4066 (emacs_sigaction_init, forwarded_signal): New decls.
4067 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4068 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4069 (sigmask, sys_sigmask): Remove; no longer needed.
4070 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4071 (sigblock, sigunblock, sigfree):
4072 (sigsetmask) [!defined sigsetmask]:
4073 Remove. All uses replaced by pthread_sigmask.
4074 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4075 no longer need to be replaced, and its typical old uses
4076 are now done via emacs_sigaction_init and sigaction.
4077 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4078 (sys_sigdel): Remove; unused.
4079 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4081 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4083 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4084 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4086 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4088 Explicitly mark buffer_defaults and buffer_local_symbols.
4089 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4090 mark_local_symbols here.
4091 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4092 since special buffers aren't marked here any more.
4093 (allocate_buffer): Chain new buffer with all_buffers here...
4094 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4096 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4097 (syms_of_buffer): Remove staticpro of the above.
4098 (init_buffer_once): Set names for buffer_defaults and
4099 buffer_local_symbols.
4101 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4103 Use bool for booleans in font-related modules.
4104 * font.c (font_intern_prop, font_style_to_value)
4105 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4106 (generate_otf_features, font_check_otf_features, font_check_otf)
4107 (font_match_p, font_list_entities, font_at):
4108 * fontset.c (fontset_id_valid_p, reorder_font_vector
4109 (fontset_find_font, Fset_fontset_font)
4110 (face_suitable_for_char_p) [0]:
4111 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4112 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4113 (m17n_flt_initialized, ftfont_shape_by_flt):
4114 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4115 * nsfont.m (nsfont_draw):
4116 * w32font.c (w32font_draw):
4117 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4118 Use bool for booleans.
4119 * font.h: Adjust to above API changes.
4120 (struct font, struct font_driver, struct font_driver_list):
4121 Use bool for booleans.
4122 (struct font): Remove useless member encoding_type.
4124 * fontset.c, xftfont.c: Omit unnecessary static decls.
4126 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4128 * alloc.c (mark_object): Revert window marking code
4129 since it's unsafe for the Fset_window_configuration.
4131 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4133 Fix race conditions with signal handlers and errno (Bug#12327).
4134 Be more systematic about preserving errno whenever a signal
4135 handler returns, even if it's not in the main thread. Do this by
4136 renaming signal handlers to distinguish between signal delivery
4137 and signal handling. All uses changed.
4138 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4139 * data.c (deliver_arith_signal): Rename from arith_error.
4140 * dispnew.c (deliver_window_change_signal): Rename from
4141 window_change_signal.
4142 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4143 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4144 * keyboard.c (deliver_input_available_signal): Rename from
4145 input_available_signal.
4146 (deliver_user_signal): Rename from handle_user_signal.
4147 (deliver_interrupt_signal): Rename from interrupt_signal.
4148 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4149 (deliver_child_signal): Rename from sigchld_handler.
4150 * atimer.c (handle_alarm_signal):
4151 * data.c (handle_arith_signal):
4152 * dispnew.c (handle_window_change_signal):
4153 * emacs.c (handle_fatal_signal, handle_danger_signal):
4154 * keyboard.c (handle_input_available_signal):
4155 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4156 * process.c (handle_pipe_signal, handle_child_signal):
4157 New functions, with the actual signal-handling code taken from the
4158 original respective signal handlers, sans the sporadic attempts to
4159 preserve errno, since that's now done by handle_on_main_thread.
4160 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4161 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4162 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4164 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4165 Move initialization of main_thread to sysdep.c's init_signals.
4166 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4167 our usage, and simplifies the mainline code.
4168 (record_child_status_change): New static function, as a helper
4169 for handle_child_signal, and with most of the old child handler's
4171 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4172 (handle_child_signal): Use the above.
4173 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4174 Moved here from emacs.c.
4175 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4176 code moved here from emacs.c's main function.
4177 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4178 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4179 This lets callers save and restore errno properly.
4181 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4183 Remove redundant or unused things here and there.
4184 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4185 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4186 * editfns.c (Fcompare_buffer_substrings): Likewise.
4187 * frame.h (struct terminal, struct font_driver_list):
4188 Remove redundant declarations.
4189 * window.h (Qleft, Qright): Likewise.
4191 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4193 Do not mark objects from deleted buffers, windows and frames.
4194 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4195 (mark_object): Likewise for windows and frames.
4197 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4199 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4200 buffer_defaults and buffer_local_symbols as valid objects.
4201 Return special value to denote them.
4203 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4205 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4206 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4207 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4208 (file_name_absolute_p, Fsubstitute_in_file_name):
4209 (check_executable, check_writable, Ffile_accessible_directory_p)
4210 (Fset_file_selinux_context, Fdefault_file_modes)
4211 (Finsert_file_contents, choose_write_coding_system)
4212 (Fwrite_region, build_annotations, a_write, e_write)
4214 * filelock.c (boot_time_initialized, get_boot_time)
4215 (get_boot_time_1, lock_file_1, within_one_second):
4216 * floatfns.c (in_float):
4217 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4218 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4219 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4220 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4221 * window.c (compare_window_configurations):
4222 Use bool for booleans.
4223 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4224 (Fdefault_file_modes): Now mode_t, not int, for modes.
4225 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4226 (internal_delete_file): Now returns void, not a (boolean) int,
4227 since nobody was looking at the return value.
4228 * lisp.h, window.h: Adjust to above API changes.
4230 * xdisp.c (set_message): Simplify and reindent last change.
4232 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4234 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4236 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4238 * eval.c (call_debugger): Make the function non-static so that we
4239 can call it from set_message.
4241 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4242 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4244 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4246 Give more-useful info on a fatal error (Bug#12328).
4247 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4248 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4249 of doing the work ourselves.
4250 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4251 do most of the work.
4252 (fatal_error_backtrace): New function, taken from the guts
4253 of the old fatal_error_signal, but with a new option to output
4255 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4256 info about the signal than just its number.
4257 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4258 * sysdep.c: Include <execinfo.h>
4259 (emacs_backtrace): New function, taken partly from the previous
4260 code of the 'die' function.
4261 (emacs_abort): Call fatal_error_backtrace rather than abort.
4263 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4265 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4266 eager (load-time) macro-expansion.
4267 * lisp.mk (lisp): Add macroexp.
4269 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4271 Simplify redefinition of 'abort' (Bug#12316).
4272 Do not try to redefine the 'abort' function. Instead, redo
4273 the code so that it calls 'emacs_abort' rather than 'abort'.
4274 This removes the need for the NO_ABORT configure-time macro
4275 and makes it easier to change the abort code to do a backtrace.
4276 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4277 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4278 Remove; sysdep.c's emacs_abort now takes its place.
4279 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4280 'abort' changed to use 'emacs_abort'.
4281 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4282 (abort) [!defined abort]: Rename to ...
4283 (emacs_abort): ... new name.
4284 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4285 the place of the old 'abort' in emacs.c.
4286 * w32.c, w32fns.c (abort): Do not #undef.
4287 * w32.c (emacs_abort): Rename from w32_abort.
4289 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4291 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4292 offsets[j].dv, since the y axis of the screen coordinates points
4293 down, while the y axis of the font definition coordinates points
4294 up. This fixes display of Arabic diacritics such as KASRA and
4295 KASRATAN. (Bug#11860)
4297 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4299 Be more systematic about _setjmp vs setjmp.
4300 * alloc.c (test_setjmp, mark_stack):
4301 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4302 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4303 (png_load, my_error_exit, jpeg_load):
4304 * process.c (send_process_trap, send_process):
4305 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4306 The underscored versions are up to 30x faster on some hosts.
4307 Formerly, the code used setjmp+longjmp sometimes and
4308 _setjmp+_longjmp at other times, with no particular reason to
4309 prefer setjmp+longjmp.
4311 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4313 Fix minor problem found by static checking.
4314 * buffer.c (Fdelete_all_overlays): Return nil.
4316 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4318 * buffer.c (Fdelete_all_overlays): New function.
4320 2012-09-03 Chong Yidong <cyd@gnu.org>
4322 * gtkutil.c: Add extern decl for Qxft.
4324 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4326 * emacs.c, eval.c: Use bool for boolean.
4327 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4328 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4329 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4330 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4331 (main, decode_env_path, Fdaemon_initialized):
4332 * eval.c (call_debugger, Finteractive_p, interactive_p):
4333 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4334 (maybe_call_debugger, Fbacktrace):
4335 * process.c (read_process_output, exec_sentinel):
4336 Use bool for booleans.
4337 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4338 All callers changed.
4339 * eval.c (interactive_p): Omit always-true boolean argument
4340 EXCLUDE_SUBRS_P. All callers changed.
4341 * dispextern.h, lisp.h: Reflect above API changes.
4342 * firstfile.c (dummy): Use the address of 'main', whose signature
4343 won't change, instead of the address of 'initialize', whose
4344 signature just changed from int to bool.
4345 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4346 * msdos.c (fatal_error_in_progress): ... from here.
4347 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4349 (redisplay_internal, unwind_redisplay): Simply clear
4350 REDISPLAYING_P when unwinding, instead of saving its previous,
4351 always-false value and then restoring it.
4353 Clean up some extern decls.
4354 Mostly, this hoists extern decls out of .c files and into .h files.
4355 That way, we're more likely to catch errors if the interfaces change.
4356 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4357 declare xg_mark_data.
4358 * dispextern.h (x_frame_parm_handlers):
4360 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4361 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4362 (Qultra_bold, Qoblique, Qitalic):
4363 Move extern decl here from .c file.
4364 * alloc.c (xg_mark_data) [USE_GTK]:
4366 * eval.c (Qlexical_binding):
4367 * fns.c (time) [!HAVE_UNISTD_H]:

4373 * process.c (QCfamily, QCfilter):
4374 * widget.c (free_frame_faces):
4375 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4376 * xfont.c (x_clear_errors):
4377 * xterm.c (x_frame_parm_handlers):
4378 Remove now-redundant extern decls.
4379 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4380 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4382 * xfaces.c: Remove unnecessary static decls.
4383 * xterm.c (updating_frame): Remove decl of nonexistent object.
4385 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4386 when building globals.h, as the objects that are not built on
4387 this host are not needed to compile C files on this host.
4389 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4391 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4393 * frame.h: Add missing prototype for x_wm_set_size_hint.
4395 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4399 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4400 (Fsubstitute_command_keys):
4401 * editfns.c (region_limit, find_field, Fconstrain_to_field)
4402 (save_excursion_save, save_excursion_restore)
4403 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
4404 (format_time_string, general_insert_function)
4405 (make_buffer_string, make_buffer_string_both)
4406 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
4407 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
4408 (copy_text, insert_1, insert_1_both, insert_from_string)

4414 (adjust_intervals_for_insertion, merge_properties_sticky)
4415 (graft_intervals_into_buffer, lookup_char_property)
4416 (adjust_for_invis_intang, set_point_both)
4417 (get_property_and_range, compare_string_intervals)
4418 (set_intervals_multibyte_1, set_intervals_multibyte):
4419 * keyboard.c (decode_timer):
4420 Use bool for boolean.
4421 * intervals.h, lisp.h, systime.h: Reflect above API changes.

4424 2012-09-02 Chong Yidong <cyd@gnu.org>
4426 * keymap.c (push_key_description): Print M-TAB as C-M-i
4429 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4431 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4432 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

4437 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4439 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4441 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4442 more than one grapheme cluster passed to the shaper: compute the
4443 offset adjustment values separately for each cluster. (Bug#11860)
4445 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4446 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4447 about implicit conversions from integer to pointer.
4449 2012-09-01 Daniel Colascione <dancol@dancol.org>
4451 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4452 system used too early.
4454 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4456 Better seed support for (random).
4457 * emacs.c (main): Call init_random.
4458 * fns.c (Frandom): Set the seed from a string argument, if given.
4459 Remove long-obsolete Gentzel cruft.
4460 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
4461 (init_random): New function.

4469 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4470 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
4471 all of which have been moved to common code.
4473 * xfaces.c: Include TERM_HEADER instead of listing all possible
4474 window-system headers.
4476 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

4480 directly accessing frame internals.
4482 * w32font.h: Include font.h. Define syms_of_w32font and
4485 * process.c: Include TERM_HEADER instead of listing all possible
4486 window-system headers.
4488 * nsterm.h: Remove declarations now in frame.h.
4489 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
4491 * menu.c: Include TERM_HEADER instead of listing all possible
4492 window-system headers.
4494 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4497 * keyboard.c: Include TERM_HEADER instead of listing all possible
4498 window-system headers.
4500 * image.c: Include TERM_HEADER instead of listing all possible
4501 window-system headers. Declare Vlibrary_cache when compiling for
4504 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4505 window system declarations.
4507 * frame.h: Move common functions here: set_frame_menubar,
4508 x_set_window_size, x_sync, x_get_focus_frame,
4509 x_set_mouse_position, x_set_mouse_pixel_position,
4510 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4530 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
4531 the current window system; include in list of objects to link into
4534 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4536 Remove mark_ttys function and fix tty_display_info initialization.
4537 * lisp.h (mark_ttys): Remove prototype.
4538 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4539 to mark_ttys because all possible values of 'top_frame' slot are
4540 the frames which are reachable from Vframe_list.
4541 * term.c (mark_ttys): Remove.
4542 (init_tty): Safely initialize 'top_frame' slot with Qnil.
4544 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4546 Change struct frame bitfields from unsigned char to unsigned.
4547 * frame.h (struct frame): Change type of 'display_preempted',
4548 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
4549 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
4550 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
4551 bitfields from unsigned char to unsigned.
4553 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4555 Remove unused member of struct x_output and struct w32_output.
4556 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
4557 * w32term.h (struct w32_output): Likewise.
4559 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
4561 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4562 does not become zero (Bug#12234).
4564 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
4566 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4567 for GCC 4.7.1 x86-64.
4569 2012-08-30 Glenn Morris <rgm@gnu.org>
4571 * lread.c (init_lread): For out-of-tree builds, only add the
4572 source directory's site-lisp dir to the load-path if it exists,
4573 consistent with in-tree builds. (Bug#12302)
4575 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
4577 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
4578 button_values to NULL. Call setStykeMask so dialogs get a close button.
4579 (windowShouldClose:): Set window_closed.
4580 (dealloc): New member, free button_values.
4581 (process_dialog:): Make member function. Remove window argument,
4582 replace window with self. Count buttons and allocate and store values
4584 (addButton:value:row:): value is int with the name tag. Call setTag
4585 with tag. Remove return self, declare return value as void.
4586 (addString:row:): Remove return self, declare return value as void.
4587 (addSplit): Remove return self, declare return value as void.
4588 (clicked:): Remove return self, declare return value as void.
4589 Set dialog_return to button_values[seltag]. Code formatting change.
4590 (initFromContents:isQuestion:): Adjust call to process_dialog.
4591 Code formatting change.
4592 (timeout_handler:): Set timer_fired to YES.
4593 (runDialogAt:): Set timer_fired to NO.
4594 Handle click on close button as quit.
4596 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4597 Add window_closed and button_values. Add void as return value for
4598 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4599 Add process_dialog as new member.
4601 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4603 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
4604 is not one of the heaps we manage. (Bug#12242)
4606 2012-08-28 Glenn Morris <rgm@gnu.org>
4608 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
4610 2012-08-28 Martin Rudalics <rudalics@gmx.at>
4612 * window.c (Fset_window_configuration): Remove handling of
4613 auto-buffer-name window parameter. Install revision of reverted
4616 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4618 Do not allow to set major mode for a dead buffer.
4619 * buffer.c (Fset_buffer_major_mode): Signal an error
4620 if the buffer is dead.
4621 (Fother_buffer, other_buffer_safely): Remove redundant
4624 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4626 Always use set_buffer_if_live to restore original buffer at unwind.
4627 * buffer.h (record_unwind_current_buffer): New function.
4628 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
4629 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
4630 * undo.c, window.c: Adjust users.
4631 * buffer.c (set_buffer_if_live): Fix comment.
4633 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4635 Fix usage of set_buffer_internal.
4636 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
4637 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
4638 * coding.c (decode_coding): Omit redundant test.
4639 * fileio.c (decide_coding_unwind): Likewise.
4640 * fns.c (secure_hash): Likewise.
4641 * insdel.c (modify_region): Likewise.
4642 * keyboard.c (command_loop_1): Likewise.
4643 * print.c (PRINTFINISH): Likewise.
4644 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
4646 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

4666 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
4667 and remove last int (actually boolean) argument, which was always 0.
4668 All callers changed.
4669 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
4670 * dispextern.h (struct composition_it): Use bool for boolean.
4671 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
4672 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
4673 * dired.c (file_name_completion):
4674 Use bool for boolean. (This was missed in an earlier change.)
4676 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4678 * window.c (Fset_window_configuration): Revert first part of
4681 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
4683 * nsterm.h (NSPanel): New class variable dialog_return.
4685 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
4686 Initialize dialog_return.
4687 (windowShouldClose:): Use stop instead of stopModalWithCode.
4688 (clicked:): Ditto, and also set dialog_return (Bug#12258).
4689 (timeout_handler:): Use stop instead of abortModal. Send a dummy
4691 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

4706 Use bool for booleans.
4707 * dired.c (file_name_completion):
4708 * process.h (fd_callback):
4709 Omit int (actually boolean) argument. It wasn't being used.
4711 * composite.h, lisp.h: Reflect above API changes.

4735 * fileio.c (Finsert_file_contents):
4736 Use bool for booleans.
4737 * coding.h, lisp.h: Reflect above API changes.
4738 * coding.c: Remove unnecessary static function decls.
4739 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4740 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4741 not a boolean 'int', since callers never look at the return value.
4742 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
4743 * coding.h (decoding_buffer_size, encoding_buffer_size)
4744 (emacs_mule_string_char): Remove unused extern decls.
4745 (struct iso_2022_spec, struct coding_system):
4746 Use 'unsigned int : 1' for boolean fields, since there's more than one.
4747 (struct emacs_mule_spec): Remove unused field 'full_support'.
4748 All initializations removed.
4749 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
4751 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4753 Fix spare memory change (Bug#12286).
4754 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4755 (valid_lisp_object_p): Likewise.
4757 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4759 * window.c (Fset_window_configuration): Record any window's old
4760 buffer if it's replaced (see Bug#8789). If the new current
4761 buffer doesn't appear in the selected window, go to its old
4764 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4766 Special MEM_TYPE_SPARE to denote reserved memory.
4767 * alloc.c (enum mem_type): New memory type.
4768 (refill_memory_reserve): Use new type for spare memory.
4769 This prevents live_cons_p and live_string_p from incorrect
4770 detection of uninitialized objects from spare memory as live.
4772 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4775 * Makefile.in (.PHONY): versioclean -> versionclean.
4777 Remove unused external symbols.
4778 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
4779 * window.c (Qwindow_valid_p, decode_valid_window):
4780 Now static, not extern.
4781 * data.c (Qinterval): Remove; unused.
4782 (syms_of_data): Do not define 'interval'.
4783 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
4784 * window.h (decode_valid_window):
4787 * character.c, charset.c, chartab.c: Use bool for booleans.

4797 (char_table_set_range, optimize_sub_char_table)
4798 (map_sub_char_table):
4799 Use bool for boolean.
4800 * character.c (str_to_unibyte): Omit last boolean argument; it was
4801 always 0. All callers changed.
4802 * character.h, charset.h: Adjust to match previous changes.
4803 * character.h (char_printable_p): Remove decl of nonexistent function.
4804 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4805 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4806 are all boolean, so make them single-bit bitfields.
4808 * lisp.h (ASET): Remove attempt to detect side effects.
4809 It was meant to be temporary and it often doesn't work,
4810 because when IDX has side effects the behavior of IDX==IDX
4811 is undefined. See Stefan Monnier in
4812 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4814 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4816 * lisp.h (functionp): New function (extracted from Ffunctionp).
4817 (FUNCTIONP): Use it.
4818 * eval.c (Ffunctionp): Use it.
4820 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4822 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4823 as that's faster and simpler than static storage. Don't bother
4824 with the g_main_context_query overhead if g_main_context_pending
4825 says no events are pending.
4826 (gfds, gfds_size): Remove these static vars.
4827 (xgselect_initialize): Remove; no longer needed.
4828 All uses and decls removed.
4830 * emacs.c (fatal_error_signal_hook): Remove.
4831 All uses removed. This leftover from old code was always 0.
4833 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4834 * casefiddle.c (casify_object, casify_region):
4835 * casetab.c (set_case_table):
4836 * category.c, category.h (word_boundary_p):
4837 * category.h (CHAR_HAS_CATEGORY):
4838 Use bool for booleans, instead of int.
4840 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4842 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4844 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4846 On assertion failure, print backtrace if available.
4847 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4848 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4849 * Makefile.in (LIB_EXECINFO): New macro.
4852 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4853 * bytecode.c (exec_byte_code):
4854 * callint.c (check_mark, Fcall_interactively):
4855 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4856 (getenv_internal, sync_process_alive, call_process_exited):
4857 * lisp.h (USE_SAFE_ALLOCA):
4858 Use bool for booleans, instead of int.
4859 * lisp.h, process.h: Adjust prototypes to match above changes.
4860 * callint.c (Fcall_interactively): Don't assume the mark's
4861 offset fits in 'int'.
4863 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4865 * buffer.c, buffer.h: Use bool for boolean.
4866 * buffer.c (reset_buffer_local_variables)

4872 (mmap_enlarge, mmap_set_vars):
4873 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4874 Use bool for booleans, instead of int.
4875 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4876 since the 1-or-0 return value is always ignored anyway.
4877 (mmap_initialized_p):
4878 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4879 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4881 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4883 * bidi.c: Use bool for boolean.
4884 This is a bit more readable, and makes the text segment of bidi.o
4885 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4886 Presumably it's faster too.
4887 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

4892 (bidi_explicit_dir_char, bidi_level_of_next_char)
4893 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4894 Use bool for booleans, instead of int.
4895 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4896 (bidi_unshelve_cache): Adjust decls to match code.
4898 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4900 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4903 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4905 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4906 * atimer.h: Include <stdbool.h>.
4908 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4910 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4911 compile time tests instead of run time tests on systems that do
4913 (FRAME_MAC_P): Remove leftover from deleted code.
4914 * frame.c (syms_of_frame): Remove leftover from deleted code.
4916 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4918 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4920 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4922 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4923 Otherwise, the compiler complains about (A?B:C) where B is void
4924 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4925 (fontset_add): Return void, for FONTSET_ADD.
4927 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4929 * alloc.c: Use bool for booleans.
4930 (gc_in_progress, abort_on_gc)
4931 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4932 (dont_register_blocks) [GC_MALLOC_CHECK]:
4933 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

4935 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4936 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4937 (mark_stack, valid_pointer_p, make_pure_string)
4938 (Fgarbage_collect, survives_gc_p, gc_sweep):
4939 Use bool for booleans, instead of int.
4940 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4941 Remove unused local.
4942 * alloc.c (PURE_POINTER_P):
4943 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4944 * editfns.c (Fformat):
4945 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4947 * fns.c (sweep_weak_table):
4948 * lisp.h (suppress_checking, push_message, survives_gc_p)
4949 (make_pure_string, gc_in_progress, abort_on_gc):
4950 * lread.c (readchar, read1):
4951 * print.c (Fprin1_to_string):
4952 * xdisp.c (push_message):
4953 Use bool for booleans affected directly or indirectly by
4956 Make recently-introduced setters macros.
4957 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4958 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4959 (set_fontset_default, set_fontset_fallback): Rename from their
4960 upper-case counterparts, and make them functions rather than macros.
4961 This is more consistent with the other recently-introduced setters.
4962 These don't need to be inline, since they're local.
4964 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4966 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4967 the loop (Bug#12247).
4969 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4971 * lisp.h (vcopy): Use memcpy rather than our own loop.
4972 This fixes a performance regression introduced by the recent
4973 addition of vcopy. This means 'vcopy' will need to be modified
4974 for a copying collector, but that's OK. Also, tighten the
4975 checking in the assertion.
4977 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4979 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4980 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4981 non-base glyph for the width of the base character, according to
4982 what x_draw_composite_glyph_string_foreground expects.
4983 Generate WADJUST value according to composition_gstring_width's
4984 expectations, to produce correct width of the composed character.
4985 Reverse the sign of the DU offset produced by ScriptPlace.
4987 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4989 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4991 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4993 Avoid direct writes to contents member of struct Lisp_Vector.
4994 * lisp.h (vcopy): New function to copy data into vector.
4995 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4996 * fns.c (Ffillarray): Use ASET.
4997 * keyboard.c (timer_check_2): Use AREF and ASET.
4998 (append_tool_bar_item, Frecent_keys): Use vcopy.

5071 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5073 Rely on <config.h> + <unistd.h> to declare 'environ',
5074 as gnulib does this if the system doesn't.
5075 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

5946 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5947 * w32.c (init_environment): Change the default values of many
5948 environment variables in dflt_envvars[] to NULL, to avoid pushing
5949 them into environment when they were not already defined.
5950 Remove the code that deletes site-lisp subdirectories from the default
5951 value of EMACSLOADPATH, as it is no longer needed.
5952 (check_windows_init_file): Now external, not static.
5953 Use Vload_path as is, without adding anything, as this function is now
5954 called when Vload_path is already set up.
5956 * w32.h (check_windows_init_file): Add prototype.
5958 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5960 compatibility with Posix platforms.
5961 (main): Move the call to check_windows_init_file to here from

5965 installation tree, as appropriate.
5967 * callproc.c (init_callproc_1): Call decode_env_path instead of
5968 doing its equivalent by hand.
5969 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5970 the code that sets Vexec_path run on MS-Windows.
5972 * lread.c (init_lread): Add comments to #ifdef's.
5974 * msdos.c (dos_set_window_size, IT_update_begin)

5982 Now constants, not macros.
5984 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
5986 Remove unnecessary casts involving pointers.
5987 These casts are no longer needed now that we assume C89 or later,
5988 since they involve casting to or from void *.

5990 (make_pure_float, make_pure_vector):
5991 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6001 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6002 Remove unnecessary pointer casts.
6003 * alloc.c (record_xmalloc): New function.
6004 * lisp.h (record_xmalloc): New decl.
6005 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6006 more like a function. This is because the pointer cast is not
6007 needed. All uses changed.
6008 * print.c (print_string, print_error_message): Avoid length recalc.
6010 Improve fix for macroexp crash with debugging (Bug#12118).
6011 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6012 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6013 not supposed to be invoked from the garbage collector.
6014 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6015 (gc_aset): New function, which is like ASET but can be
6016 used in the garbage collector.
6017 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6032 headers (most versions of MinGW w32api don't).
6033 (get_security_info, create_symbolic_link)
6034 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6036 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6037 in the argument file name.

6040 (sys_rename): Diagnose renaming of a symlink when the user doesn't
6041 have the required privileges.
6042 (get_file_security_desc_by_name): Rename from
6043 get_file_security_desc.

6045 with addition of handling of symlinks and support for 'lstat'.
6046 If possible, get file's attributes and security information by
6047 handle, not by name. Produce S_IFLNK bit for symlinks, when
6048 called from 'lstat'.
6049 (stat, lstat): New functions, call 'stat_worker'.
6050 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6051 symlinks when the underlying filesystem supports them.
6053 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6055 Fix macroexp crash on Windows with debugging (Bug#12118).
6056 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6057 checking subscripts; problem introduced with the recent
6058 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6059 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6060 since it's used in non-static inline functions now.
6062 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6063 Don't assume buffer size fits in 'int'. Remove unused local.

6083 * composite.c (COMPOSITE_INLINE):
6084 * dispnew.c (DISPEXTERN_INLINE):
6085 * sysdep.c (SYSTIME_INLINE):
6086 Define to EXTERN_INLINE, so that the corresponding functions
6087 are compiled into code.
6088 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6089 (INLINE_HEADER_END): New macros.
6090 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6112 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6114 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6115 This how ASET and AREF are supposed to work, and makes
6116 it easier to think about future improvements. See
6117 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6118 * charset.h (set_charset_attr): New function.

6371 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
6372 does that unconditionally. Remove file, which is now empty.
6374 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
6377 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

6392 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
6393 Move to after the definition of struct Lisp_Char_Table,
6394 since the former now needs that type defined.

6495 * w32inevt.c: Include w32inevt.h.
6496 (w32_read_console_input): New inline function, calls either
6497 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6498 w32_console_unicode_input.
6499 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6500 (w32_kbd_patch_key, key_event): Use the codepage returned by
6501 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
6502 (key_event): use uChar.UnicodeChar only if
6503 w32_console_unicode_input is non-zero.

6530 * alloc.c (listn): Fix the order the arguments are consed onto the
6533 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6534 enumeration constants, as PURE and HEAP are too general, and clash
6535 with other headers and sources, such as gmalloc.c and the
6536 MS-Windows system headers. All users changed.
6538 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6540 Revert last save_excursion_save and save_excursion_restore changes.
6541 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6551 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
6553 Improve GDB symbol export (Bug#12036).
6554 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6555 arms of an 'if', not using conditional expressions; otherwise GDB
6556 complains about the types in the unevaluated arm when the argument
6557 is an integer literal.
6558 (xgetint): Simplify expression.
6559 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6560 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6561 Zaretskii in <http://bugs.gnu.org/12036#13>.
6562 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6563 needed now that we have gdb_make_enums_visible.
6564 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6565 (enum enum_USE_LSB_TAG):
6566 New enum types, packaging up enums that need to be exported to GDB.
6568 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

6584 * xdisp.c (syms_of_xdisp): Likewise.
6585 * xfns.c (syms_of_xfns): Likewise.
6587 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6589 Fast save_excursion_save and save_excursion_restore.
6590 * lisp.h (struct Lisp_Excursion): New data type.
6591 (PVEC_EXCURSION): New pseudovector type.
6592 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6593 to deal with it. Adjust comments.

6604 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6606 Fix export of symbols to GDB (Bug#12036).
6607 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6608 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6609 emacs.c, as this is a more-suitable home. Had this been done earlier
6610 the fix for 12036 would have avoided some of the problems noted in
6611 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6612 would have been more obvious.
6613 * emacs.c: Do not include <verify.h>; no longer needed.
6614 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6615 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6616 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6617 Remove; now done in lisp.h.
6618 * lisp.h (PUBLISH_TO_GDB): New macro.

6620 (DATA_SEG_BITS): Use it.
6621 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6622 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6623 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6624 not be usable in #if. This simplifies things.
6626 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6628 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6630 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

6633 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6634 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6635 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6636 Adjust to changes in lisp.h and emacs.c, by using
6637 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6638 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6639 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6640 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6641 instead of gdb_valbits.
6642 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6643 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6644 instead of gdb_array_mark_flag.
6645 (xboolvector): Get size from $->size, not $->header.size.
6646 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6647 (xreload, hook-run, hookpost-run): Remove.
6648 * emacs.c: Include <verify.h>.
6649 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6650 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6652 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6653 (gdb_USE_LSB_TAG): New enum constants.
6654 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6655 Also define these as enum constants, so they're visible to GDB.
6656 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6657 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6658 as constants, so they're visible to GDB.
6659 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6660 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6661 Now enum constants, not macros, so they're visible to GDB.
6662 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6663 more convenient now. All uses changed.
6664 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6665 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6667 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
6669 Explicitly free restriction data that are not needed anymore.
6670 * editfns.c (save_restriction_restore): Free restriction data.
6672 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6674 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6675 add argument, tune behavior, and adjust all callers.
6677 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6679 Use typedef for EMACS_INT, EMACS_UINT.
6680 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6681 than macros. This simplifies debugging in the usual case, since
6682 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6683 and it allows expressions involving EMACS_INT casts.
6684 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6686 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
6688 * nsterm.m (ns_read_socket): Return early if there is a modal
6691 2012-07-25 Martin Rudalics <rudalics@gmx.at>

6694 that FOCUS-FRAME can be omitted.
6696 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6698 Adjust buffer text indirection counters at the end of Fkill_buffer.
6699 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6700 buffer is definitely dead. This should really fix an issue reported
6701 by Christoph Scholtes again. (Bug#12007).
6702 (init_buffer_once): Initialize indirection counters of
6703 buffer_defaults and buffer_local_symbols (for sanity and safety).
6705 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6707 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6708 and continuation glyphs on tooltip frames, leave them at zero.
6709 Avoids continued lines in tooltips. (Bug#11832)
6711 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6713 Simplify copy_overlay.
6714 * buffer.c (copy_overlay): Simplify. Use build_marker.

6720 or invalid. (Bug#12025)
6722 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
6723 it signals an error when a tooltip frame is being created.
6725 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6727 Cleanup miscellaneous objects allocation and initialization.
6728 * alloc.c (allocate_misc): Change to static. Add argument to
6729 specify the subtype. Adjust comment and users.
6730 (build_overlay): New function.
6731 * buffer.c (copy_overlays, Fmake_overlay): Use it.
6732 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
6733 (allocate_misc): Remove prototype.
6734 (build_overlay): Add prototype.
6736 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6738 Swap buffer text indirection counters in Fbuffer_swap_text.
6739 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6740 This avoids crash reported by Christoph Scholtes at
6741 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6743 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6745 * nsmenu.m (Popdown_data): New struct.
6746 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
6748 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
6749 (initWithContentRect): Make imgView and contentView non-static
6750 and autorelease them. Also autorelease img and matrix (Bug#12005).
6751 (dealloc): Remove (Bug#12005).
6753 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
6755 Adjust consing_since_gc when objects are explicitly freed.

7499 * s/aix4-2.h (unix): Remove; no longer needed.
7501 EMACS_TIME simplification (Bug#11875).
7502 This replaces macros (which typically do not work in GDB)

7504 The functional style also makes code easier to read and maintain.
7505 * systime.h: Include <sys/time.h> on all hosts, not just if
7506 WINDOWSNT, since 'struct timeval' is needed in general.

7541 (menu_separator_name_p):

7546 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7547 Prefer snprintf to strncpy.
7548 * nsterm.m (ns_term_init):
7549 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7550 * nsterm.m (ns_term_init):
7551 Avoid the need for strncpy, by using build_string or
7552 make_unibyte_string directly. Use dtoastr, not snprintf.
7553 * process.c (Fmake_network_process): Diagnose service names that
7554 are too long, rather than silently truncating them or creating
7555 non-null-terminated names.
7556 (Fnetwork_interface_info): Likewise, for interface names.
7557 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7558 Prefer sprintf to strncat.

7572 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7573 where argument type is known to be a Lisp_Cons.

7589 the function is called with compile-time constant argument.
7590 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7591 argument, adjust users accordingly. Use build_pure_c_string where

7625 We include usg5-4-common.h, which defines them both.
7627 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7628 O_RDONLY already includes it).
7630 Stop ns builds setting the EMACSLOADPATH environment variable.
7631 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7632 Now it does not set EMACSLOADPATH, just returns the load-path string.
7633 * nsterm.h: Update accordingly.
7634 * lread.c [HAVE_NS]: Include nsterm.h.
7635 (init_lread) [HAVE_NS]: Use ns_load_path.
7636 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7638 2012-07-09 Glenn Morris <rgm@gnu.org>
7640 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7641 since the included bsd-common.h does so.

7644 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7645 (ns_init_paths): Do not set EMACSPATH.
7646 * nsterm.h (ns_exec_path): Add it.
7647 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7650 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7652 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>

7655 when read_kbd || !NILP (wait_for_cell); fix this.
7657 Add GCC-style 'const' attribute to functions that can use it.
7658 * character.h (char_resolve_modifier_mask):
7659 * keyboard.h (make_ctrl_char):
7660 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7669 Add decls with ATTRIBUTE_CONST.
7671 Minor improvements to make_formatted_string.
7672 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7673 where int is good enough, as vsprintf returns an int.
7674 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7676 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7678 Use make_formatted_string to avoid double length calculation.
7679 * lisp.h (make_formatted_string): New prototype.
7680 * alloc.c (make_formatted_string): New function.

7684 * filelock.c (get_boot_time): Likewise.
7685 * frame.c (make_terminal_frame, set_term_frame_name)
7686 (x_report_frame_params): Likewise.

7699 * nsterm.h (ns_etc_directory): Add it.
7700 * callproc.c [HAVE_NS]: Include nsterm.h.
7701 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
7703 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7705 Move marker debugging code under MARKER_DEBUG.
7706 * marker.c (MARKER_DEBUG): Move marker debugging code under
7707 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7708 for bootstrap with --enable-checking (~3x slowdown reported
7709 by Juanma Barranquero <lekktu@gmail.com>).
7710 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7712 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7714 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7715 See <http://bugs.gnu.org/11825#29>.
7717 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7719 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7720 has no font, use the frame's font. (Bug#11813)
7721 (display_line): Add commentary about displaying truncation glyphs
7723 (produce_special_glyphs): Move here from term.c.
7725 * term.c (produce_special_glyphs): Move to xdisp.c.
7727 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7730 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7732 * xdisp.c (display_line): Avoid warning about implicit declaration
7735 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7737 * lisp.h: Remove empty conditional.
7739 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7741 * lread.c (load_path_check): Now static.
7743 Fix some minor --with-ns problems found by static checking.
7744 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7745 (x_set_font) [!HAVE_X_WINDOWS]:
7746 * image.c (xpm_load_image) [HAVE_NS]:
7747 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7748 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7749 Remove unused local.
7750 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7751 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7752 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7753 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7754 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7755 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:

7758 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7760 2012-07-07 Glenn Morris <rgm@gnu.org>
7762 * lread.c (load_path_check): New function, split from init_lread.
7763 (init_lread): Reorganize. Motivation:
7764 If EMACSLOADPATH is set, check/warn about that rather than the
7765 defaults, which we are not going to use. Hence we can remove
7766 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7767 Don't warn if site-lisp directories are missing.
7768 If not installed, start from a blank load-path, since
7769 PATH_LOADSEARCH refers to the eventual installation directories.
7771 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7773 Support truncation and continuation glyphs on GUI frames, when
7774 fringes are disabled. (Bug#11832)
7775 * xdisp.c (init_iterator): Get dimensions of truncation and
7776 continuation glyphs even if on GUI frames.
7777 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7778 or both, are absent.
7779 (start_display, move_it_in_display_line_to): Handle the case of a
7780 GUI frame without a fringe to display continuation or truncation
7782 (insert_left_trunc_glyphs): Support GUI frames: make sure
7783 truncation glyphs overwrite enough glyphs from the current line to
7784 have sufficient space in pixels.
7785 (display_line): Support truncation and continuation glyphs on GUI
7786 frames. If some spare pixels are left on the line after inserting
7787 the truncation glyphs, fill that space with a stretch glyph of a
7788 suitably computed width.
7790 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7791 produce_glyphs, to support GUI sessions.
7793 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7795 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7797 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7799 Do not require float-time's arg to fit in time_t (Bug#11825).
7800 This works better on hosts where time_t is unsigned, and where
7801 float-time is applied to the (negative) difference between two times.
7802 * editfns.c (decode_time_components): Last arg is now double *,
7803 not int *, and means to store all the result as a double, without
7804 worrying about whether the seconds part fits in time_t.
7805 All callers changed.
7806 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7807 All callers changed.
7808 (Ffloat_time): Do not fail merely because the specified time falls
7809 outside of time_t range.
7811 2012-07-07 Glenn Morris <rgm@gnu.org>
7813 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7820 Update dependencies.
7822 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7824 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

7828 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7829 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7830 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

7833 * xfont.c (compare_font_names): Redo to omit the need for casts.
7835 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7837 * xfns.c (Fx_change_window_property): Doc fix.
7838 * w32fns.c (Fx_change_window_property): Doc fix.
7840 * w32fns.c (Fx_window_property): Accept the same arguments as the
7841 X Windows version. Doc fix.
7842 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7844 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7845 Eli Zaretskii <eliz@gnu.org>
7847 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7848 Windows-specific code from nt/config.nt moved here.
7849 Obsolete settings removed.
7851 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7853 * process.c: Avoid unnecessary calls to gettime.
7854 (wait_reading_process_output): Don't get the time of day
7855 when gobbling data immediately and not waiting, as there's no need
7856 for it in that case. This removes a FIXME.
7858 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7860 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7861 is defined (Bug#11768).
7863 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7865 Fix marker debugging code.
7866 * marker.c (byte_char_debug_check): Do not perform the check
7867 if buffer is not multibyte.
7868 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7869 Call byte_char_debug_check with correct arguments.
7871 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7873 Compile marker debugging code only if ENABLE_CHECKING is defined.
7874 * marker.c (byte_char_debug_check, count_markers):
7875 Use only if ENABLE_CHECKING is defined.
7876 (byte_debug_flag): Remove.
7877 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7878 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7880 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7882 Avoid code repetition in marker-related functions.
7883 * marker.c (attach_marker): New function.
7884 (Fset_marker, set_marker_restricted, set_marker_both)
7885 (set_marker_restricted_both): Use it.
7886 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7887 Consistently rename charno to charpos.
7888 (marker_position): Add eassert.
7889 (marker_byte_position): Convert to eassert.

7904 * editfns.c (buildmark): Remove.
7905 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7906 (save_restriction_save): Use build_marker.
7907 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7908 * window.c (save_window_save): Likewise.
7910 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7912 Do not use Fdelete_overlay in delete_all_overlays
7913 to avoid redundant calls to unchain_overlay.
7914 * buffer.c (drop_overlay): New function.
7915 (delete_all_overlays, Fdelete_overlay): Use it.
7916 * minibuf.c (get_minibuffer): Fix comment.
7918 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7920 Port to OpenBSD 5.1 amd64.
7921 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7922 This is needed for OpenBSD, and should be harmless on all BSD systems.
7923 Also, include <sys/sysctl.h>, as it should be available on all
7924 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7925 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7926 use p_pid member, not kp_proc.pid.
7928 2012-07-06 Glenn Morris <rgm@gnu.org>
7930 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7932 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7934 More xmalloc and related cleanup.
7935 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7936 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

7941 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
7942 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7943 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7945 Omit needless casts involving void * pointers and allocation.
7946 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7947 as the former is more robust if P's type is changed.
7948 Prefer xzalloc to xmalloc + memset 0.
7949 Simplify malloc-or-realloc to realloc.
7950 Don't worry about xmalloc returning a null pointer.
7951 Prefer xstrdup to xmalloc + strcpy.
7952 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7954 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7955 alloca of a constant.
7957 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7959 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7960 hscroll is larger than the line width. Fixes long and futile
7961 looping inside extend_face_to_end_of_line (on a TTY) producing
7962 glyphs that are not needed and thrown away.
7964 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7966 * marker.c (set_marker_restricted_both): Simplify by using

7980 followed by gtk_box_set_homogeneous (Bug#11768).
7981 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7982 (update_theme_scrollbar_width, xg_create_scroll_bar):
7983 Use gtk_scrollbar_new (Bug#11768).
7984 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7985 (is_box_type): New function (Bug#11768).
7986 (xg_tool_item_stale_p): Call is_box_type.
7987 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
7988 with default display (Bug#11768).

7992 * xdisp.c (window_hscroll_limited): New function.
7993 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7994 coordinates when window's hscroll is set to insanely large
7997 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7999 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8000 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

8066 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8067 This should be fixed in a better way; see Eli Zaretskii in
8068 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8069 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8071 * fileio.c (time_error_value): Rename from special_mtime.
8072 The old name's problems were noted by Eli Zaretskii in
8073 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8075 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8076 This variable's comment says Emacs needs at least one GDB-visible
8077 symbol of type enum pvec_type, to work around GDB problems.
8078 The symbol's value doesn't matter.
8080 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8081 that causes compilation to fail on pre-C99 compilers.
8083 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8085 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

8109 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8110 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8111 abusing vector->header.next.nbytes.
8112 (live_vector_p): Use PVEC_TYPE.
8113 (mark_object): Adapt code to extract pvectype. Use switch.
8115 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8117 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8118 Tighten new eassert a bit.
8120 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8122 Fix compilation with --enable-gcc-warnings and -O1
8124 * doprnt.c (doprnt): Change type of tem to int, initialize
8125 to avoid compiler warning. Add eassert.
8126 * search.c (simple_search): Initialize match_byte to avoid
8127 compiler warning. Add eassert.
8129 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8131 Avoid weird behavior with large horizontal scrolls.
8132 Without this change, for example, large hscroll values would
8133 mess up Emacs's display on Fedora 15 x86, presumably due to
8134 overflows in int calculations in the display code.
8135 Also, if buffers had long lines, Emacs would freeze.
8136 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8137 (set_window_hscroll): New function, containing the old guts of
8138 Fset_window_hscroll. Return the clipped value.
8139 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8140 This avoids the need to check against PTRDIFF_MAX.
8142 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8144 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8146 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8148 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8150 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8151 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8152 since GCC 4.4.6 issues a bogus warning for them.
8154 Fix bugs in file timestamp newness comparisons.
8155 * fileio.c (Ffile_newer_than_file_p):
8156 * lread.c (Fload): Use full timestamp resolution of files,
8157 not just the 1-second resolution, so that files that are only
8158 slightly newer still count as newer.
8159 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8160 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8162 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8164 * fileio.c: Improve handling of file time marker. (Bug#11852)
8165 (special_mtime): New function.
8166 (Finsert_file_contents, Fverify_visited_file_modtime):
8167 Use it to set special mtime values consistently.
8169 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8171 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8172 marker for non-existing file. (Bug#11852)
8174 2012-07-03 Glenn Morris <rgm@gnu.org>
8176 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8177 and did not make it into globals.h).
8179 2012-07-03 Tom Tromey <tromey@redhat.com>
8181 * window.c (Fset_window_margins, Fset_window_fringes)
8182 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8183 * textprop.c (Fprevious_property_change): No longer static.
8184 * syntax.c (Fsyntax_table_p): No longer static.

8199 * dired.c (Ffile_attributes): No longer static.
8200 * composite.c (Fcomposition_get_gstring): No longer static.
8201 * callproc.c (Fgetenv_internal): No longer static.
8203 * ccl.h: Remove EXFUNs.
8204 * buffer.h: Remove EXFUNs.
8205 * dispextern.h: Remove EXFUNs.
8206 * intervals.h: Remove EXFUNs.
8207 * fontset.h: Remove EXFUN.
8208 * font.h: Remove EXFUNs.
8209 * dosfns.c (system_process_attributes): Remove EXFUN.
8210 * keymap.h: Remove EXFUNs.
8211 * lisp.h: Remove EXFUNs.
8212 * w32term.h: Remove EXFUNs.
8213 * window.h: Remove EXFUNs.
8214 * xsettings.h: Remove EXFUN.
8215 * xterm.h: Remove EXFUN.
8217 2012-07-03 Glenn Morris <rgm@gnu.org>
8219 * lisp.h (Frandom): Make it visible to C.
8220 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8221 buffer for invisible buffers. (Bug#1229)
8223 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8225 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8226 values which aren't power of 2.
8227 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8228 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8231 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8233 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8235 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8237 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8239 * alloc.c (allocate_vector_block): Remove redundant
8240 calls to mallopt if DOUG_LEA_MALLOC is defined.
8241 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8242 avoid calls to mallopt if zero_vector is returned.
8244 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8246 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8247 is enabled, avoid dereferencing NULL current_sblock if
8250 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8252 Cleanup basic buffer management.
8253 * buffer.h (struct buffer): Change layout to use generic vector
8254 marking code. Fix some comments. Change type of 'clip_changed'
8255 to bitfield. Remove unused #ifndef old.
8256 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8257 (GET_OVERLAYS_AT): Fix indentation.
8258 (for_each_per_buffer_object_at): New macro.
8259 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8260 (Fbuffer_local_variables): Use it.
8261 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8262 * alloc.c (allocate_buffer): Adjust to match new layout of
8263 struct buffer. Fix comment.
8264 (mark_overlay): New function.
8265 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8266 Lisp area of struct buffer.
8267 (mark_object): Use it. Adjust marking of misc objects
8268 and related comments.
8270 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8272 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8273 wrapper that is not needed because the wrapped code is a no-op (zero
8274 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8275 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8277 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8279 * alloc.c (mark_buffer): Simplify. Remove prototype.
8280 (mark_object): Add comment. Reorganize marking of vector-like
8281 objects. Use CHECK_LIVE for all vector-like objects except buffers
8282 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8283 Avoid redundant calls to mark_vectorlike for bool vectors.
8285 2012-06-30 Glenn Morris <rgm@gnu.org>
8287 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8289 * epaths.in (PATH_SITELOADSEARCH): New.
8290 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8291 This is rather than relying on --enable-locallisppath elements
8292 having "site-lisp" in their names. (Bug#10208#25, 11658)
8294 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8296 * w32proc.c (sys_select): Accept and ignore one more argument.
8298 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8300 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8301 (pselect) [!MS_DOS]: Redirect to sys_select.
8303 * sysdep.c: Don't include dos.h and dosfns.h.
8305 * process.c (sys_select):
8306 * msdos.c (sys_select): Accept one more argument and ignore it.
8308 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8309 adapt data types and code to that.
8312 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8313 which clashes with the gnulib function of the same name.
8315 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8317 * font.c (font_style_to_value, font_style_symbolic)
8318 (font_prop_validate_style): Add type checks for values in
8321 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8323 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8326 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8328 * xdisp.c (try_window_id): Undo last change.
8330 * w32.c (getwd): Adjust commentary about startup_dir.
8331 (init_environment): Always call sys_access, even in non-MSVC
8332 builds. Don't chdir to the directory of the Emacs executable.
8333 This undoes code from 1997 which was justified by the need to
8334 "avoid conflicts when removing and renaming directories". But its
8335 downside was that every relative file name was being interpreted
8336 relative to the directory of the Emacs executable, which can never
8337 be TRT. In particular, it broke sys_access when called with
8338 relative file names.
8339 (sys_access): Map GetLastError to errno.
8341 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8343 * window.h (struct window): Change type of 'fringes_outside_margins'

8347 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8350 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8352 * gnutls.c (emacs_gnutls_handshake):
8353 Add QUIT to make the loop interruptible.
8355 2012-06-29 Glenn Morris <rgm@gnu.org>
8357 * charset.c (init_charset): Make lack of etc/charsets fatal.
8359 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8361 * editfns.c (region_limit): Fix type mismatch.
8363 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8365 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8366 undefined. Convert from xassert to eassert.
8367 * nsmenu.m: Convert from xassert to eassert.
8368 * nsterm.m: Likewise.
8370 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8372 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8374 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8376 Avoid integer overflow on scroll-left and scroll-right.
8377 * window.c (HSCROLL_MAX): New macro.
8378 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8379 overflow when requested scroll falls outside ptrdiff_t range.
8381 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8383 * window.h (struct window): Change type of 'hscroll',
8384 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8385 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8386 Adjust users accordingly.
8387 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8388 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8389 from EMACS_INT to ptrdiff_t.
8390 (make_window): Omit redundant initialization.
8392 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8396 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

8465 * alloc.c (allocate_string): Omit intervals initialization.
8466 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8467 as in make_pure_string and make_pure_c_string.

8471 * alloc.c (allocate_string): Fix last change.
8473 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8523 * alloc.c: Remove build_string.
8524 * lisp.h: Define build_string as static inline. This provides
8525 a better opportunity to optimize away calls to strlen when the
8526 function is called with compile-time constant argument.
8527 * image.c (imagemagick_error): Convert to build_string.
8528 * w32proc.c (sys_spawnve): Likewise.
8529 * xterm.c (x_term_init): Likewise.
8531 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8533 Use sprintf return value instead of invoking strlen on result.
8534 In the old days this wasn't portable, since some sprintf
8535 implementations returned char *. But they died out years ago and
8536 Emacs already assumes sprintf returns int.
8537 Similarly for float_to_string.
8538 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8539 * ccl.c (ccl_driver):
8540 * character.c (string_escape_byte8):

8543 * print.c (print_object):
8544 * xdisp.c (message_dolog):
8545 * xfns.c (syms_of_xfns):
8546 Use sprintf or float_to_string result to avoid need to call strlen.
8547 * data.c (Fnumber_to_string):
8548 Use make_unibyte_string, since the string must be ASCII.
8549 * lisp.h, print.c (float_to_string): Now returns int length.
8550 * term.c (produce_glyphless_glyph):
8551 Use sprintf result rather than recomputing it.
8553 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8554 * Makefile.in (ALL_CFLAGS):

8561 strcasecmp if available.

8586 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8591 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8592 instead of truncating it to 63 (admittedly a generous limit).
8594 * process.c: Fix spelling and caps in comments.
8596 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8598 * emacs.c (setpgrp): Remove definition, unused.

8608 (SYSTIME_H): Add nt/inc/sys/time.h.
8610 * systime.h [WINDOWSNT]: Include sys/time.h.
8612 * s/ms-w32.h (struct timespec): Definition moved from
8613 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
8615 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

8722 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8724 Support higher-resolution time stamps (Bug#9000).
8725 The time stamps are only nanosecond-resolution at the C level,
8726 since that's the best that any real-world system supports now.
8727 But they are picosecond-resolution at the Lisp level, as that's
8728 easy, and leaves room for future OS improvements.
8730 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8733 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8734 Don't get current time unless it's needed.
8736 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8737 now provides it if it's absent.
8738 (start_atimer): Port to higher-res time stamps.
8739 Check for time stamp overflow. Don't get current time more
8740 often than is needed.
8742 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8743 Include systime.h, not time.h.
8744 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8746 * dired.c: Include stat-time.h.
8747 (Ffile-attributes): File times now have higher resolution.
8749 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8750 (struct image): Timestamp now has higher resolution.
8752 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8753 has at least microseconds now. All uses removed.
8754 (update_frame, update_single_window, update_window, update_frame_1)
8755 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8756 (duration_to_sec_usec): Remove; no longer needed.
8758 * editfns.c (time_overflow): Now extern.

8764 (decode_time_components, lisp_seconds_argument): New functions.
8765 (make_time): Now static.
8766 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8767 Report an error if the time is invalid, rather than having the caller
8770 * fileio.c: Include <stat-time.h>
8771 (Fcopy_file): Copy higher-resolution time stamps.
8772 Prefer to set the time stamp via a file descriptor if that works.

8774 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8775 (Fvisited_file_modtime, Fset_visited_file_modtime):
8776 Support higher-resolution time stamps.
8778 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8780 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8782 * image.c (prepare_image_for_display, clear_image_cache)
8783 (lookup_image): Port to higer-resolution time stamps.
8785 * keyboard.c (start_polling, bind_polling_period):
8786 Check for time stamp overflow.
8787 (read_char, kbd_buffer_get_event, timer_start_idle)
8788 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8789 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8790 Port to higher-resolution time stamps. Do not assume time_t is signed.
8791 (decode_timer): New function. Timers are now vectors of length 9,
8792 not 8, to accommodate the picosecond component.
8793 (timer_check_2): Use it.
8795 * nsterm.m (select_timeout, timeval_subtract): Remove.
8796 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8797 as they're a bit more accurate and handle overflow better.
8798 (ns_select): Change prototype to be compatible with pselect.
8799 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8800 * nsterm.h (ns_select): Adjust prototype.
8802 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8803 us-resolution time stamps.
8804 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8806 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8808 * lisp.h (time_overflow): New decl.
8809 (wait_reading_process_output): First arg is now intmax_t, not int,
8810 to accommodate larger waits.
8812 * process.h (struct Lisp_Process.read_output_delay):
8813 Now counts nanoseconds, not microseconds.
8814 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8816 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8817 (wait_reading_process_output):
8818 Port to ns-resolution time stamps.
8819 (Faccept_process_output, wait_reading_process_output):
8820 Check for time stamp overflow. Do not assume time_t is signed.
8821 (select_wrapper): Remove; we now use pselect.
8822 (Fprocess_attributes): Now generates ns-resolution time stamps.
8824 * sysdep.c: Include utimens.h. Don't include utime.h
8825 or worry about struct utimbuf; gnulib does that for us now.
8826 (gettimeofday): Remove; gnulib provides a substitute.
8827 (make_timeval): New function.
8828 (set_file_times): Now sets ns-resolution time stamps.
8829 New arg FD; all uses changed.
8830 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8831 (system_process_attributes):
8832 Now returns ns-resolution time stamp. All uses changed.
8833 Check for time stamp overflow.
8835 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8836 provides a substitute now.
8838 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8839 since it guarantees struct timespec.
8840 (EMACS_TIME): Now struct timespec, so that we can support
8841 ns-resolution time stamps.
8842 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8843 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8844 (EMACS_USECS): Remove.
8845 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8846 so multiply the arg by 1000 before storing it.
8847 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8849 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8850 Port to ns-resolution time stamps.
8851 (EMACS_TIME_NEG_P): Remove; replaced by....
8852 (EMACS_TIME_SIGN): New macro.
8853 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8854 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8855 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8856 (make_timeval, make_lisp_time, decode_time_components): New decls.
8857 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8858 that it mishandled time_t overflow. You can't compare by subtracting!
8859 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8860 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8862 * term.c: Include <sys/time.h>.
8863 (timeval_to_Time): New function, for proper overflow wraparound.

8868 (Fprimitive_undo): Use them when restoring time stamps.
8870 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8871 (w32_get_internal_run_time):
8872 Port to higher-resolution Emacs time stamps.
8873 (ltime): Now accepts single 64-bit integer, as that's more convenient
8876 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8878 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8879 for compatibility with pselect. Support ns-resolution time stamps.
8881 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8883 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8884 Check for time stamp overflow, and support ns-resolution time stamps.
8886 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8887 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8888 (timeval_subtract): Remove; no longer needed.
8889 (XTflash, XTring_bell, x_wait_for_event):
8890 Port to ns-resolution time stamps. Don't assume time_t is signed.
8892 2012-06-22 Chong Yidong <cyd@gnu.org>

8896 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8898 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8899 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8900 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8901 staticidx goes up to 1597 out of 1600 = 0x640.)
8903 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8905 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8906 Otherwise, the umask might be mistakenly 0 while handling input signals.

8920 2012-06-19 Chong Yidong <cyd@gnu.org>
8922 * frame.c (delete_frame): When selecting a frame on a different

8927 (unwind_format_mode_line): Restore them.
8928 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8930 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8931 since tty frames can be explicitly named.
8932 (prepare_menu_bars): Likewise.
8934 * term.c (Ftty_top_frame): New function.
8936 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8939 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8940 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8941 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8942 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8943 (METER_1, METER_2): Simplify.

8949 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8951 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8952 gets killed during executing of this function (Bug#11665).
8953 Try to always return Qt when the buffer has been actually killed.
8954 (Vkill_buffer_query_functions): In doc-string say that functions
8955 run by this hook should not change the current buffer.
8957 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8959 Fix recently-introduced process.c problems found by static checking.

8977 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8979 * lisp.h (eassert): Assume C89 or later.
8980 This removes the need for CHECK.
8981 (CHECK): Remove. Its comments about always evaluating its
8982 argument were confusing, as 'eassert' typically does not evaluate
8985 * coding.c (produce_chars): Use ptrdiff_t, not int.
8987 * xterm.c (x_draw_underwave): Check for integer overflow.
8988 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9172 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
9173 code works fine either way, and efficiency is not a concern here,
9174 as the union type is for debugging, not for production.
9175 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9176 Use an inline function on all platforms when using the union type,
9177 since this is simpler and 'static inline' can be used portably
9179 (LISP_INITIALLY_ZERO): New macro.
9180 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
9181 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

9319 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9321 * doprnt.c (doprnt): Truncate multibyte char correctly.
9322 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9323 would mishandle a string argument "Xc" if X was a multibyte
9324 character of length 2: it would truncate after X's first byte
9325 rather than including all of X.
9327 2012-06-06 Chong Yidong <cyd@gnu.org>
9329 * buffer.c (word_wrap): Doc fix.

9378 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9379 Convert pctcpu and pctmem to Lisp float properly.
9380 Let the compiler fold better, as 100.0/0x8000 is exact.
9382 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9384 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9387 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9389 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9391 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>

9394 bitfields where appropriate, remove unused fields.
9395 * window.h (struct window): Remove unused 'last_mark_x' and
9396 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

9398 Change type of 'force_start', 'optional_new_start',
9399 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9400 fields from Lisp_Object to bitfield. Adjust users accordingly.

9408 and 'double' in a couple of places.
9410 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9412 * xdisp.c (handle_stop): Detect whether we have overlay strings
9413 loaded by testing it->current.overlay_string_index to be
9414 non-negative, instead of checking whether n_overlay_strings is
9415 positive. (Bug#11587)
9417 2012-05-31 Chong Yidong <cyd@gnu.org>
9419 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

9425 * search.c (search_buffer): Remove calls to
9426 r_alloc_inhibit_buffer_relocation, as it is now called by
9427 maybe_unify_char, which was the cause of relocation of buffer text
9430 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9432 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9433 for the duration of call to load_charset, to avoid problems with
9434 callers of maybe_unify_char that access buffer text through C
9437 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9438 decrement the inhibition flag, instead of just setting or
9441 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9443 Remove obsolete '#define static' cruft.
9444 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9445 This #undef was "temporary" in 2000; it is no longer needed
9446 now that '#define static' has gone away.
9447 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9448 (gray_bitmap_bits): Remove; no longer needed.
9449 All uses replaced with definiens.

9461 (safe_bcopy): Remove decl; no longer has that name.
9462 (main): Coalesce #if into single bit of code, for simplicity.

9493 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9494 Bug#9642, but explicitly check that the buffer the overlay would
9495 be moved to is live and rearrange lines to make sure that errors
9496 will not put the overlay in an inconsistent state.
9497 (Fdelete_overlay): Cosmetics.
9499 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9501 * w32term.c (my_bring_window_to_top): New function.

9540 before checking whether it's out of range. Put the check inside
9542 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

9552 defined on ralloc.c.
9554 * buffer.c [REL_ALLOC]: Remove prototypes of

9560 * search.c (search_buffer): Use it to inhibit relocation of buffer
9561 text while re_search_2 is doing its job, because re_search_2 is
9562 passed C pointers to buffer text. (Bug#11519)
9564 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9567 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9568 state after an additional call to move_it_in_display_line_to, keep
9569 the values of it->max_ascent and it->max_descent found for the

9577 Fix coding-related core dumps with gcc -ftrapv.
9578 The code was computing A - B, where A and B are pointers, and B is
9579 random garbage. This can lead to core dumps on platforms that
9580 have special pointer registers, and it also leads to core dumps on
9581 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9582 A - B only when B is initialized properly.
9583 * coding.c (coding_set_source, coding_set_destination): Return void.
9584 (coding_change_source, coding_change_destinations): New functions,
9585 with the old behaviors of coding_set_source and coding_set_destination.

9603 * w32inevt.c: Include termchar.h and window.h.
9604 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9605 moves, call note_mouse_highlight. If help_echo changed, call
9606 gen_help_event to produce help-echo message in the echo area.
9607 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9610 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>

9613 with GCC 4.7.0 on x86-64.
9615 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9617 * bidi.c (bidi_mirror_char): Revert last change: an int is
9618 definitely wide enough here.
9620 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

9634 Use int, not EMACS_INT, where int is wide enough.

9655 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9656 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9657 (validate_region): Omit unnecessary test for b <= e,
9658 since that's guaranteed by the previous test.
9659 (adjust_overlays_for_delete): Avoid pos + length overflow.
9660 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9661 (report_overlay_modification):

9663 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

9672 not int, to avoid needless 32-bit limit on 64-bit hosts.
9673 (exec_byte_code): Use tighter memory-full test, one that checks
9674 for alloca overflow. Don't compute the address of the object just
9675 before an array, as that's not portable. Use EMACS_INT, not
9676 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9677 * callint.c (Fcall_interactively):
9678 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9690 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9691 (casify_object): Avoid integer overflow when overallocating buffer.
9692 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9693 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9694 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9695 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9696 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

9699 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9700 For CCL_MapSingle, check that content and value are in int range.

9702 Check that Vcode_version_map_vector is a vector.
9703 (resolve_symbol_ccl_program): Check that vector header is in range.
9704 Always copy the vector, so that we can check its contents reliably
9705 now rather than having to recheck each instruction as it's being
9706 executed. Check that vector words fit in 'int'.
9707 (ccl_get_compiled_code, Fregister_ccl_program)
9708 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9709 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

9711 contents are in range.
9712 (Fccl_execute_on_string): Check that status is in range.
9713 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9714 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9715 Accept and return EMACS_INT, not int, because callers can pass values

9722 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9724 avoid mishandling large integers.

9735 Don't rely on undefined behavior with signed left shift overflow.
9736 Don't assume unsigned int fits into fixnum, or that fixnum fits
9737 into unsigned int. Don't require max_code to be a valid fixnum;
9738 that's not true for gb10830 4-byte on a 32-bit host. Allow
9739 invalid_code to be a cons, for the same reason. Require code_offset
9740 to be a character. Avoid int overflow if max_char is close
9742 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9743 this is intended anyway and avoids some undefined behavior.
9744 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9745 INDEX_TO_CODE_POINT, as that's what it expects.
9746 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9747 * charset.h (DECODE_CHAR): Return int, not unsigned;
9748 this is what was intended anyway, and it avoids undefined behavior.
9749 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9750 integer-overflow issues.
9751 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9752 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9753 where the argument is EMACS_INT, and this behavior is not intended.
9754 * chartab.c (Fmake_char_table, Fset_char_table_range)
9755 (uniprop_get_decoder, uniprop_get_encoder):
9756 Don't assume fixnum fits in int.
9757 * cmds.c (move_point): New function, that does the gist of
9758 Fforward_char and Fbackward_char, but does so while checking
9759 for integer overflow more accurately.
9760 (Fforward_char, Fbackward_char): Use it.
9761 (Fforward_line, Fend_of_line, internal_self_insert)
9762 (internal_self_insert):
9763 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10478 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
10480 Assume C89 or later.

10536 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10538 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10540 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10542 * lread.c (init_obarray): Declare Qt and Qnil as special.
10544 2012-05-14 Glenn Morris <rgm@gnu.org>
10546 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10547 Put "libexec" before "bin", for the sake of init_callproc_1.
10549 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10551 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

10554 (report_error, report_error_1, make_hdr, copy_sym)
10555 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10556 Make arguments const char *, not char *, to avoid violations of C
10557 standard and to fix some AIX warnings reported by Gilles Pion.
10559 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10561 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10562 already have overlays loaded.
10563 (handle_single_display_spec): Before returning without displaying
10564 fringe bitmap, synchronize the bidi iterator with the main display
10565 iterator, by calling iterate_out_of_display_property.
10566 (iterate_out_of_display_property): Detect buffer iteration by
10567 testing that it->string is a Lisp string.
10568 (get_next_display_element): When the current object is exhausted,
10569 and there's something on it->stack, call set_iterator_to_next to
10570 proceed with what's on the stack, instead of returning zero.
10571 (set_iterator_to_next): If called at the end of a Lisp string,
10572 proceed to consider_string_end without incrementing string
10573 position. Don't increment display vector index past the end of
10574 the display vector. (Bug#11417)
10575 (pos_visible_p): Don't report a position visible when move_it_to
10576 stopped at the last line of window, which happens to be scanned
10577 backwards by the bidi iteration. (Bug#11464)
10579 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10581 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10582 and right-margin display specs even if the spec is invalid or we
10583 are on a TTY, and thus unable to display on the fringes.
10584 That's because the text with the property will not be displayed anyway,
10585 so we need to signal to the caller that this is a "replacing"
10586 display spec. This fixes display when the spec is invalid or we
10589 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10591 * unexaix.c (make_hdr): Fix typo in prototype.
10592 This bug broke the build on AIX. Problem reported by Gilles Pion.
10594 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10596 * keyboard.c (kbd_buffer_get_event): Read special events also in

10607 2012-05-12 Glenn Morris <rgm@gnu.org>
10609 * Makefile.in (MKDIR_P): New, set by configure.
10610 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10612 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

10622 Update dependencies.
10624 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10626 * xgselect.c (xg_select): Put maxfds+1 into a var.
10627 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10629 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10631 2012-05-10 Dave Abrahams <dave@boostpro.com>
10633 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10634 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10636 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10638 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10639 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10640 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10641 Initialize xd_registered_buses.
10643 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10645 Untag more efficiently if USE_LSB_TAG.
10646 This is based on a proposal by YAMAMOTO Mitsuharu in
10647 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10648 For an admittedly artificial (nth 8000 longlist) benchmark on
10649 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10650 Emacs's overall text size by 1%.
10651 * lisp.h (XUNTAG): New macro.
10652 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10653 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10654 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10655 * eval.c (Fautoload):
10656 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10657 * frame.h (XFRAME): Use XUNTAG.
10659 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10660 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10661 Remove unportable assumptions about print widths of types like
10663 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10664 intptr_t when converting between pointer and integer, to avoid GCC
10665 warnings about wrong width.
10667 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10669 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10670 stack for each reader_thread, instead of defaulting to 8MB
10671 determined by the linker. This avoids failures in creating
10672 subprocesses on Windows 7, see the discussion in this thread:
10673 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10675 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10677 Fix up display of the *Minibuf-0* buffer in the mini window.
10678 * keyboard.c (read_char): Don't clear the echo area if there's no
10680 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10681 contents of *Minibuf-0*) if there's no message displayed in its stead.
10683 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10685 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10688 2012-05-06 Chong Yidong <cyd@gnu.org>
10690 * lisp.mk (lisp): Update.
10692 2012-05-05 Jim Meyering <meyering@redhat.com>
10694 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10696 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10698 * data.c (PUT_ERROR): New macro.
10699 (syms_of_data): Use it. Add new error type `user-error'.
10700 * undo.c (user_error): New function.
10701 (Fprimitive_undo): Use it.
10702 * print.c (print_error_message): Adjust print style for `user-error'.
10703 * keyboard.c (user_error): New function.
10704 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10706 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10708 Do not limit current-time-string to years 1000..9999.
10709 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10710 (Fcurrent_time_string): Support any year that is supported by the
10711 underlying localtime representation. Don't use asctime, as it
10712 has undefined behavior for years outside the range -999..9999.
10714 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10716 Fix race conditions involving setenv, gmtime, localtime, asctime.
10717 Without this fix, interrupts could mess up code that uses these
10718 nonreentrant functions, since setting TZ invalidates existing
10719 tm_zone or tzname values, and since most of these functions return
10720 pointers to static storage.
10721 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10722 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10723 Grow the critical sections to include not just invoking
10724 localtime/gmtime, but also accessing these functions' results
10725 including their tm_zone values if any, and any related TZ setting.
10726 (format_time_string): Last arg is now struct tm *, not struct tm **,
10727 so that the struct tm is saved in the critical section.
10728 All callers changed. Simplify allocation of initial buffer, partly
10729 motivated by the fact that memory allocation needs to be outside
10730 the critical section.
10732 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10734 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10735 with RESET_INTERVAL.
10737 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10738 Remove duplicated buffer name initialization.
10740 2012-05-02 Jim Meyering <jim@meyering.net>
10742 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10744 * xfns.c (x_window): Use xstrdup (Bug#11375).
10746 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10748 * xdisp.c (pos_visible_p): If already at a newline from the
10749 display string before the 'while' loop, don't walk back the glyphs
10750 from it3.glyph_row. Solves assertion violation when the display
10751 string begins with a newline (egg.el). (Bug#11367)
10753 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10755 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10758 2012-05-01 Glenn Morris <rgm@gnu.org>
10760 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10761 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10762 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10763 All were removed before 23.1.
10765 * dispnew.c: Remove HAVE_LIBNCURSES test;
10766 it is always true on relevant platforms.
10768 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10769 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10771 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10773 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10775 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10776 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10779 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10781 Do not avoid creating empty evaporating overlays (Bug#9642).
10782 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10783 That is, do not delete an evaporating overlay if it becomes
10784 empty after its bounds are adjusted to fit within its buffer.
10785 This fix caused other problems, and I'm reverting it until we get
10786 to the bottom of them.
10788 2012-04-27 Chong Yidong <cyd@gnu.org>
10790 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10792 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10794 * xdisp.c (pos_visible_p): If the window start position is beyond
10795 ZV, start the display from buffer beginning. Prevents assertion
10796 violation in init_iterator when the minibuffer window is scrolled
10797 via the scroll bar.
10799 * window.c (window_scroll_pixel_based): Likewise.
10801 2012-04-27 Chong Yidong <cyd@gnu.org>
10803 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10805 2012-04-27 Glenn Morris <rgm@gnu.org>
10807 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10808 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10810 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10812 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10813 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10815 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10817 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10818 display element, check also the underlying string or buffer
10819 character. (Bug#11341)
10821 * w32menu.c: Include w32heap.h.
10822 (add_menu_item): If the call to AppendMenuW (via
10823 unicode_append_menu) fails, disable Unicode menus only if we are
10824 running on Windows 9X/Me.
10826 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10828 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10829 (xgetint): Add missing shift for LSB tags.
10831 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10833 * keyboard.c (read_char): Don't wipe echo area for select window
10834 events: These might get delayed via `mouse-autoselect-window'
10837 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10839 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10840 manipulation of :loaded-from data.
10842 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10844 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10845 now a cons (bug#11311).
10847 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10849 Do not create empty overlays with the evaporate property (Bug#9642).
10850 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10851 if it becomes empty after its bounds are adjusted to fit within
10852 its buffer. Without this fix, in a nonempty buffer (let ((o
10853 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10854 yields an empty overlay that has the evaporate property, which is
10855 not supposed to happen.
10857 Fix minor GTK3 problems found by static checking.
10858 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

10875 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10877 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10878 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10879 (__malloc_size_t, __malloc_ptrdiff_t):
10880 Remove. All uses removed, replaced by the definiens if needed,
10881 since we can assume C89 or better now.
10882 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10890 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10891 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10892 Define using prototypes, not old style.

10957 * alloc.c: Handle unusual debugging option combinations.
10958 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10959 since the two debugging options are incompatible.
10960 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

11066 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
11067 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
11068 (r_alloc_sbrk): Now static.
11070 Improve ralloc.c interface checking.
11071 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
11072 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

11086 * alloc.c (union aligned_Lisp_Symbol): Define.
11087 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
11088 aligned_Lisp_Symbol instead of struct Lisp_Symbol.
11089 (union aligned_Lisp_Misc): Define.
11090 (MARKER_BLOCK_SIZE, struct marker_block): Use union
11091 aligned_Lisp_Misc instead of union Lisp_Misc.
11092 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
11094 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
11096 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11097 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11098 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11099 * s/netbsd.h, s/sol2-6.h:
11100 Remove definition of GC_MARK_STACK, since the default now works.
11101 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11102 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11103 no longer the default.
11104 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11106 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11108 * lread.c (lisp_file_lexically_bound_p):
11109 Fix hang at ";-*-\n" (bug#11238).
11111 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11113 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11114 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
11116 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
11118 * nsterm.m (constrainFrameRect): Always constrain when there is only
11119 one screen (Bug#10962).
11121 2012-04-13 Ken Brown <kbrown@cornell.edu>
11123 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
11125 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11127 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11129 2012-04-11 Daniel Colascione <dancol@dancol.org>
11131 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11132 against is gone. It's better to use vfork now so that when Cygwin
11133 gains a new, working vfork, we use it automatically (bug#10398).
11135 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11137 * window.c (save_window_save): Obey window-point-insertion-type.

11149 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
11150 (force_quit_count): New var.
11151 (handle_interrupt): Use it.
11153 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11155 * w32.c (w32_delayed_load): Record the full path of the library
11156 being loaded (bug#10424).
11158 2012-04-09 Glenn Morris <rgm@gnu.org>
11160 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11161 not just in the obarray, before snarfing them. (Bug#11036)
11163 * Makefile.in ($(leimdir)/leim-list.el):
11164 Pass EMACS rather than BUILT_EMACS.
11166 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11168 * process.c (make_process):
11169 * process.h: Add integer `gnutls_handshakes_tried' member to
11172 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
11173 Add convenience `GNUTLS_LOG2i' macro.
11175 * gnutls.c (gnutls_log_function2i): Convenience log function.
11176 (emacs_gnutls_read): Use new log functions,
11177 `gnutls_handshakes_tried' process member, and
11178 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11179 attempts per process (connection).
11181 2012-04-09 Chong Yidong <cyd@gnu.org>
11183 * eval.c (Fuser_variable_p, user_variable_p_eh)
11184 (lisp_indirect_variable): Functions deleted.
11185 (Fdefvar): Caller changed.
11187 * callint.c (Finteractive, Fcall_interactively):
11188 * minibuf.c (Fread_variable): Callers changed.
11190 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11192 * xdisp.c (set_cursor_from_row): If the display string appears in
11193 the buffer at position that is closer to point than the position
11194 after the display string, display the cursor on the first glyph of
11195 the display string. Fixes cursor display when a 'display' text
11196 property immediately follows invisible text. (Bug#11094)
11198 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11200 composite.c: use 'double' consistently
11201 * composite.c (get_composition_id): Use 'double' consistently
11202 instead of converting 'float' to 'double' and vice versa; this is
11203 easier to understand and avoids a GCC warning.
11205 2012-04-09 Glenn Morris <rgm@gnu.org>
11207 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11208 preparation for dumping it with emacs. (Bug#4789)
11209 (leimdir): New variable.
11210 ($(leimdir)/leim-list.el): New rule.
11211 (emacs$(EXEEXT)): Depend on leim-list.el.
11213 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
11214 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
11215 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
11217 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
11219 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
11222 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
11224 * xml.c (init_libxml2_functions) [WINDOWSNT]:
11225 Remove unused local variable.
11227 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11229 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11230 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11231 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11232 objects, as mark_maybe_pointer will catch them otherwise.
11233 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11234 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
11236 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11238 Fix typo that broke non-Windows builds.
11239 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
11241 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11243 Support building on MS-Windows with libxml2.
11245 * makefile.w32-in (OBJ2): Add xml.$(O).
11246 (GLOBAL_SOURCES): Add xml.c.
11247 ($(BLD)/xml.$(O)): New dependency list.
11249 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11250 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11251 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11252 [!WINDOWSNT]: New macros.
11253 (init_libxml2_functions, libxml2_loaded_p): New functions.
11254 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11255 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11256 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11257 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11259 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11260 Call init_libxml2_functions before calling libxml2 functions.
11261 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11263 * emacs.c: Don't include libxml/parser.h.
11264 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11265 xmlCleanupParser directly.
11267 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11269 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11271 * indent.c (Fvertical_motion): If there is a display string at
11272 point, use it.vpos to compute how many lines to backtrack after
11273 move_it_to point. (Bug#11133)
11275 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11277 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11278 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11279 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11280 macros related to unification of CJK characters. For the details,
11281 see the discussion following the message here:
11282 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11284 2012-04-04 Chong Yidong <cyd@gnu.org>
11286 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11288 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11290 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
11291 instead of alloca. (Bug#11138)
11293 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
11295 * w32menu.c (is_simple_dialog): Properly check lisp types.
11298 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11300 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11301 position we get to after a call to move_it_to fails the
11302 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11303 only if we wind up in a string from display property. (Bug#11063)
11305 * window.c (Fdelete_other_windows_internal): Invalidate the row
11306 and column information about mouse highlight, so that redisplay
11307 restores it after reallocating the glyph matrices. (Bug#7464)
11309 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11310 string comes from a `display' text property, use the buffer
11311 position of that property as if we actually saw that position in
11313 (move_it_by_lines): Remove the assertion that
11314 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11315 violated when there's a before-string at the beginning of a line.
11318 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11320 * xdisp.c (append_space_for_newline): If the default face was
11321 remapped, use the remapped face for the appended newline.
11322 (extend_face_to_end_of_line): Use the remapped default face for
11323 extending the face to the end of the line.
11324 (display_line): Call extend_face_to_end_of_line when the default
11325 face was remapped. (Bug#11068)
11327 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11329 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11331 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11333 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11335 2012-03-27 Glenn Morris <rgm@gnu.org>
11337 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11340 2012-03-26 Kenichi Handa <handa@m17n.org>
11342 * dispextern.h (struct glyph): Fix previous change. Change the
11343 bit length of glyphless.ch to 25 (Bug#11082).
11345 2012-03-26 Chong Yidong <cyd@gnu.org>
11347 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11348 (command_loop_1): Use it; inhibit selection update for
11349 handle-select-window too (Bug#8996).
11351 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11353 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11355 2012-03-25 Kenichi Handa <handa@m17n.org>
11357 * dispextern.h (struct glyph): Change the bit length of
11358 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11360 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11362 * s/ms-w32.h (tzname): Include time.h before redirecting to
11363 _tzname. Fixes the MSVC build. (Bug#9960)
11365 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11367 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11370 * xterm.c (XTread_socket): Only modify handling_signal if
11371 !SYNC_INPUT. (Bug#11080)
11373 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11375 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11376 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11377 when fetching a multibyte character consumes more bytes than
11378 CHAR_BYTES returns, due to unification of CJK characters in
11379 string_char. (Bug#11073)
11381 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11383 * process.c (wait_reading_process_output): Handle pty disconnect
11384 by refraining from sending oneself a SIGCHLD (bug#10933).
11386 2012-03-22 Chong Yidong <cyd@gnu.org>
11388 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11390 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11391 Mark string as coming from a prefix property.
11392 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11393 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11395 2012-03-21 Chong Yidong <cyd@gnu.org>
11397 * xfaces.c (Vface_remapping_alist): Doc fix.
11399 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11401 * w32proc.c (Fw32_set_console_codepage)
11402 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
11405 2012-03-20 Chong Yidong <cyd@gnu.org>
11407 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11408 to reflect default non-nil value of redisplay-dont-pause.
11410 2012-03-19 Kenichi Handa <handa@m17n.org>
11412 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11413 it fit in a valid range (Bug#11003).
11415 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11417 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11418 that is not from display property, accept the row as a "cursor
11419 row" if one of the string's character has a non-nil `cursor'
11420 property. Fixes cursor positioning when there are newlines in
11421 overlay strings, e.g. in icomplete.el. (Bug#11035)
11423 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11425 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11427 2012-03-12 Chong Yidong <cyd@gnu.org>
11429 * eval.c (inhibit_lisp_code): Rename from
11430 inhibit_window_configuration_change_hook; move from window.c.
11432 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11433 * window.c (run_window_configuration_change_hook)
11434 (syms_of_window): Callers changed.
11436 2012-03-11 Chong Yidong <cyd@gnu.org>
11438 * keymap.c (Fkey_description): Doc fix (Bug#9700).
11440 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
11442 2012-03-10 Chong Yidong <cyd@gnu.org>
11444 * frame.c (other_visible_frames): Don't assume the selected frame
11445 is visible (Bug#10955).
11447 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11449 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11451 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11453 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11454 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11457 2012-03-03 Glenn Morris <rgm@gnu.org>
11459 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11461 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11463 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11464 position past the first glyph_row that ends at ZV. (Bug#10902)
11465 (redisplay_window, next_element_from_string): Fix typos in
11467 (redisplay_window): Pass to move_it_vertically the margin in
11468 pixels, not in screen lines.
11470 2012-03-02 Glenn Morris <rgm@gnu.org>
11472 * buffer.c (buffer-list-update-hook): Doc fix.
11474 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11476 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11477 push_it before setting up the iterator for the first overlay
11478 string, even if we have an empty string loaded.
11479 (next_overlay_string): If there's an empty string on the iterator
11480 stack, pop the stack. (Bug#10903)
11482 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11484 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11485 Suggested by Stefan Monnier in
11486 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11487 * alloc.c (widen_to_Lisp_Object): New static function.
11488 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11489 and widening them to Lisp_Objects. This would work even if
11490 USE_LSB_TAG is defined and wide integers are used, which might
11491 happen in a future version of Emacs.
11493 2012-02-25 Chong Yidong <cyd@gnu.org>
11495 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11498 * xselect.c (Fx_selection_exists_p): Doc fix.
11499 (x_clipboard_manager_save_all): Print an informative message
11500 before saving to clipboard manager.
11502 2012-02-24 Chong Yidong <cyd@gnu.org>
11504 * keyboard.c (process_special_events): Handle all X selection
11505 requests in kbd_buffer, not just the next one (Bug#8869).
11507 2012-02-23 Chong Yidong <cyd@gnu.org>
11509 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11510 call when setting menu-bar-lines and tool-bar-lines parameters.
11511 (unwind_create_frame_1): New helper function.
11513 * window.c (inhibit_window_configuration_change_hook): New var.
11514 (run_window_configuration_change_hook): Obey it.
11515 (syms_of_window): Initialize it.
11517 2012-02-22 Chong Yidong <cyd@gnu.org>
11519 * xterm.c (x_draw_image_relief): Add missing type check for
11520 Vtool_bar_button_margin (Bug#10743).
11522 2012-02-21 Chong Yidong <cyd@gnu.org>
11524 * fileio.c (Vfile_name_handler_alist): Doc fix.
11526 * buffer.c (Fget_file_buffer): Protect against invalid file
11527 handler return value.
11529 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11531 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11532 when computing $valmask.
11534 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11535 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11536 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11537 It's useless in that case, and it can cause problems on hosts
11538 that allocate halves of EMACS_INT values separately.
11539 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11540 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11541 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11542 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11543 it avoids undefined behavior on hosts where shifting right by more
11544 than the word width has undefined behavior.
11546 2012-02-19 Chong Yidong <cyd@gnu.org>
11548 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11549 (Funhandled_file_name_directory, Ffile_name_as_directory)
11550 (Fdirectory_file_name, Fexpand_file_name)

12161 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12162 verifies glyph row's hash code--we have just reallocated the

12327 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12328 is set, removing the need for VIRT_ADDRESS_VARIES.
12329 (PURE_P): Use a more-efficient implementation that needs just one

12336 consistency with the new puresize.h.
12337 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12338 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12345 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12346 behave as if the cursor position were at the window margin.
12348 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12349 and the cursor position is out of bounds, behave as if the cursor
12350 position were at the window margin. (Bug#10075)
12352 2011-11-18 Chong Yidong <cyd@gnu.org>
12354 * window.c (Fwindow_combination_limit): Make first argument

12376 compute_line_metrics.
12377 (compute_line_metrics): Call row_hash, instead of computing the
12380 * dispnew.c (verify_row_hash): Call row_hash for computing the
12381 hash code of a row, instead of duplicating code from xdisp.c.
12383 * dispextern.h (row_hash): Add prototype.
12385 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12387 * frame.c (delete_frame): Don't delete the terminal when the last

12436 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12437 with user-defined heap size. Bump the default size of the temacs

12441 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12442 current_matrix and desired_matrix. (Bug#9990)
12443 (verify_row_hash) [XASSERTS]: New function.

12488 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12490 Avoid some portability problems by eschewing 'extern inline' functions.
12491 The trivial performance wins aren't worth the portability hassles; see
12492 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12494 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12542 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
12543 This is also needed for porting to any host where GC_MARK_STACK is
12544 not GC_MAKE_GCPROS_NOOPS.
12545 (which_symbols): Use it.
12547 2011-11-07 Kenichi Handa <handa@m17n.org>

12560 * xmenu.c (cleanup_widget_value_tree): New function.
12561 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
12562 calling free_menubar_widget_value_tree directly (Bug#9830).
12564 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
12566 Fix some portability problems with 'inline'.

12568 (window_box_width, window_box_left, window_box_left_offset)
12569 (window_box_right, window_box_right_offset): Declare extern.
12570 Otherwise, these inline functions do not conform to C99 and
12571 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12572 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12573 * intervals.c (adjust_intervals_for_insertion)
12574 (adjust_intervals_for_deletion): Now extern, because otherwise the
12575 extern inline functions 'offset_intervals' couldn't refer to it.
12576 (static_offset_intervals): Remove.
12577 (offset_intervals): Rewrite using the old contents of
12578 static_offset_intervals. The old version didn't conform to C99
12579 because an extern inline function contained a reference to an
12580 identifier with static linkage.
12582 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>

12602 (Fwindow_vscroll): Doc fix.

12604 argument, since it makes no sense to pass a live window and for
12605 consistency with window-child.

12645 Move terminal->reference_count++ just before making the frame
12646 official. Move initialization of image_cache_refcount and
12647 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

12815 (w32font_open_internal, compute_metrics):
12816 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12817 instead of calling the "wide" APIs directly.

12821 * w32.h (syms_of_w32font): Add prototype.
12823 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

12832 * process.c (make_process): Set gnutls_state to NULL.

12884 (bidi_resolve_weak): Don't enter the expensive loop if the current
12885 position is before next_en_pos. Record the bidi type of the first
12886 non-ET, non-BN character we find, in addition to its position.
12887 (bidi_level_of_next_char): Invalidate next_en_type when
12888 next_en_pos is over-stepped.
12890 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12892 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12893 * editfns.c: Rewrite current-time-zone so that it invokes
12894 the equivalent of (format-time-string "%Z") to get the time zone name.
12895 This fixes a bug when the time zone name contains characters that
12896 need converting from the system time locale to Emacs internal format.
12897 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12898 that patch fixed format-time-string to do the conversion, but
12899 I forgot to fix current-time-zone.
12900 (format_time_string): New function, containing most of
12901 what Fformat_time_string used to contain.
12902 (Fformat_time_string): Rewrite in terms of format_time_string.
12903 This doesn't change this function's behavior.
12904 (current-time-zone): Rewrite to use format_time_string.
12905 This fixes the bug reported by Michael Schierl in
12906 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12907 Jason Rumney's 2007-06-07 change worked around this bug, but
12909 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12911 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12913 * xdisp.c (start_display): If the character at POS is displayed
12914 via a display vector, reset IT->current.dpvec_index to zero.
12915 (try_window_reusing_current_matrix): If a line ends in a display
12916 vector or the next line starts in a display vector, continue
12917 redrawing the window even though the character position of
12918 start_row was reached.
12921 2011-10-18 Chong Yidong <cyd@gnu.org>
12923 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12924 with nobreak-char-display too.
12926 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12928 Fix part 3 of bug#9771.
12929 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12930 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12931 non-neutral characters if the current character is a paragraph
12932 separator (a.k.a. Newline). This avoids running the same
12933 expensive loop twice, once when we consume the preceding newline
12934 and the other time when the line actually needs to be displayed.
12935 Avoid the loop when we see neutrals on the base embedding level
12936 following a character whose directionality is the same as the
12937 paragraph's. This avoids running the expensive loop when a line
12938 ends in a long sequence of neutrals, like control characters.
12939 Add assertion against STRONG_AL type. Slightly rearrange code
12940 that determines the type of a neutral given the first non-neutral
12942 (bidi_level_of_next_char): Set next_en_pos to zero when
12943 invalidating its info.
12945 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12947 * xdisp.c (push_display_prop): Determine whether to record string
12948 or buffer position by IT->string, not by IT->method. Allow
12949 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12950 (move_it_vertically_backward): Don't look for character position
12951 immediately after the newline when in a continuation line.
12954 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12956 * window.c (coordinates_in_window): Rewrite and delabelize
12957 vertical border check. (Bug#5357) (Bug#9618)
12959 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12961 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12962 errors in XSetWindowBorder (bug#9310).
12964 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12966 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12967 avoid crash when xmalloc overrun checking is enabled.
12969 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12971 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12972 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12973 cursor motion with <left> and <right> arrow keys.
12975 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12976 some callers set that themselves.
12978 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12980 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12981 display string and the previous row comes from the same string and
12982 is empty. (Bug#9739) (Bug#9738)
12984 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12986 * doc.c (get_doc_string): Encode file name (bug#9735).
12988 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12990 * bidi.c (bidi_level_of_next_char):
12991 * xdisp.c (get_visually_first_element): Remove old incorrect
12992 comments regarding the Unicode Line Separator character.
12994 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12996 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12998 * alloc.c (Fgc_status): Do not access beyond zombies array
12999 boundary if nzombies > MAX_ZOMBIES.
13000 * alloc.c (dump_zombies): Add missing format specifier.
13002 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13004 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13005 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13007 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13008 Some packages use them to denote characters with modifiers.
13010 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13012 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13013 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13014 matching a pp-number. Rename parameter var to var1.
13016 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13018 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13020 2011-10-08 Glenn Morris <rgm@gnu.org>
13022 * callint.c (Fcall_interactively): Give a more explicit error for the
13023 'c' case with a non-character input. (Bug#8479)
13025 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13027 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13029 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13030 lines that are hscrolled on the left.
13032 * dispnew.c (buffer_posn_from_coords): Account for a possible
13033 presence of header-line. (Bug#4426)
13035 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13037 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13038 Don't advertise functionality which we discourage or doesn't work.
13040 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13042 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13043 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13044 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13045 this makes Emacs dump core during garbage collection on rare
13046 occasions. sizeof is obviously inferior to offsetof here, so
13047 stick with offsetof.
13048 (GC_POINTER_ALIGNMENT): New macro.
13049 (mark_memory): Omit 3rd (offset) arg; caller changed.
13050 Don't assume EMACS_INT alignment is the same as pointer alignment.
13052 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13054 * keyboard.c (read_key_sequence_remapped): New var.
13055 (read_key_sequence): Compute remapping in the right buffer.
13056 (command_loop_1): Use read_key_sequence's remapping directly.
13058 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13060 * dired.c (file_name_completion): Don't expand file name.
13061 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13062 before checking file name handler.
13064 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13065 they've been requested explicitly (bug#9591).
13067 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13069 * keymap.c (Fsingle_key_description): Use make_specified_string
13070 instead of build_string to build string from push_key_description.
13073 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13075 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13076 This fixes a Y2038 bug on 64-bit hosts.
13077 * buffer.c (reset_buffer):
13078 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13079 (Fclear_buffer_auto_save_failure):
13080 Use 0, not -1, to represent an unset failure time, since time_t
13081 might not be signed.
13083 Remove dependency on glibc malloc internals.
13084 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13085 Move back here from lisp.h, but with their new implementations.
13086 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13087 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13088 * charset.c (charset_table_init): New static var.
13089 (syms_of_charset): Use it instead of xmalloc. This removes a
13090 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13091 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13092 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13093 Move back to alloc.c.
13094 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13095 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13097 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13099 * nsterm.m (windowDidResize): Call x_set_window_size only when
13100 ns_in_resize is true. Otherwise set pixelwidth/height and
13101 call change_frame_size (Bug#9628).
13103 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13105 Port --enable-checking=all to Fedora 14 x86-64.
13106 * charset.c (syms_of_charset): Also account for glibc malloc's
13107 internal overhead when calculating the initial malloc maximum.
13109 Port --enable-checking=all to Fedora 14 x86.
13110 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13112 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13113 (overrun_check_realloc, overrun_check_free):
13114 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13115 That way, xmalloc returns a properly-aligned pointer even if
13116 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13117 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13118 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13119 into account when calculating the initial malloc maximum.
13120 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13121 Move here from alloc.c, so that charset.c can use it too.
13122 Properly align; the old code wasn't right for common 32-bit hosts
13123 when configured with --enable-checking=all.
13124 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13125 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13127 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13129 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13132 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13134 * xdisp.c (compute_display_string_end): If there's no display
13135 string at CHARPOS, return -1.
13137 * bidi.c (bidi_fetch_char): When compute_display_string_end
13138 returns a negative value, treat the character as a normal
13139 character not covered by a display string. (Bug#9624)
13141 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13143 * lread.c (Fread_from_string): Fix typo in docstring.
13145 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13147 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13148 newline, reseat the iterator instead of bidi-iterating there one
13149 character at a time. (Bug#9610)
13150 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13151 TO_CHARPOS if the bidi iterator is at base embedding level.
13153 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13155 * lread.c (readevalloop): Use correct code for NBSP.
13156 (read1): Likewise. (Bug#9608)
13158 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13160 * dbusbind.c (Fdbus_register_signal): When service is not
13161 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13163 2011-09-25 Glenn Morris <rgm@gnu.org>
13165 * buffer.c (truncate-lines): Doc fix.
13167 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13169 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13170 (Fset_window_next_buffers): Doc fix.
13172 2011-09-24 Glenn Morris <rgm@gnu.org>
13174 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13176 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13178 Fix minor problems found by static checking.
13179 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13180 * indent.c (Fvertical_motion): Fix == vs = typo.
13182 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13184 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13185 Default value is now t. Doc fix.
13187 * indent.c (Fvertical_motion): Compute and apply the overshoot
13188 logic when moving up, not only when moving down. Fix the
13189 confusing name and values of the it_overshoot_expected variable;
13190 logic changes accordingly. (Bug#9254) (Bug#9549)
13192 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13193 CHARPOS is covered by a display string which includes newlines.
13194 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13195 is covered by a display string with embedded newlines.
13197 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13199 * dbusbind.c (Fdbus_register_signal): Add match rule to
13200 Vdbus_registered_objects_table. (Bug#9581)
13201 (Fdbus_register_method, Vdbus_registered_objects_table):
13204 2011-09-24 Jim Meyering <meyering@redhat.com>
13206 do not ignore write error for any output size
13207 The previous change was incomplete.
13208 While it makes emacs --batch detect the vast majority of stdout
13209 write failures, errors were still ignored whenever the output size is
13210 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13211 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13212 && echo FAIL: ignored write error
13213 FAIL: ignored write error
13214 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13215 && echo FAIL: ignored write error
13216 FAIL: ignored write error
13217 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13219 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13221 * emacs.c (Fkill_emacs): In noninteractive mode exit
13222 non-successfully if a write error occurred on stdout. (Bug#9574)
13224 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13226 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13229 * dispextern.h (struct it): Update the comment documenting what
13232 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13234 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13235 a display string, extend search for cursor position to end of row.
13236 (find_row_edges): If the row ends in a newline from a display
13237 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13238 Handle the case of a display string with multiple newlines.
13239 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13240 non-empty line. Fixes confusing cursor motion with arrow keys at
13241 the beginning of a line that starts with whitespace.
13243 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13245 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13248 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13250 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13251 boolean (Bug#9154).
13253 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13255 * xdisp.c (display_line): Record maximum and minimum buffer
13256 positions even if no glyphs were produced (e.g., by a zero-width
13257 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13258 buffer positions that will be removed from the glyph row because
13260 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13261 column is beyond frame width: don't subtract 1 "pixel" when
13262 computing width of the stretch.
13263 (reseat_at_next_visible_line_start): Undo the change made on
13264 2011-09-17 that saved paragraph information and restored it after
13265 the call to `reseat'. (Bug#9545)
13267 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13269 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13270 and turn window cursor on if cleared (Bug#9415).
13272 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13274 * search.c (boyer_moore): Take unibyte characters from pattern
13275 literally. (Bug#9458)
13277 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13279 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13281 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13283 Fix minor problem found by static checking.
13284 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13285 initialized, to pacify gcc -Wuninitialized.
13287 * fileio.c: Report proper errno when syscall falls.
13288 (Finsert_file_contents): Save and restore errno,
13289 so that report_file_error outputs the correct diagnostic.
13290 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13292 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13294 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13296 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13298 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13299 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)

13303 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13304 about the current paragraph and restore it after the call to reseat.
13306 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13307 (bidi_find_paragraph_start): Search back for paragraph beginning
13308 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13309 (bidi_move_to_visually_next): Only trigger paragraph-related
13310 computations when the last character is a newline or at EOB, not
13311 just any NEUTRAL_B. (Bug#9470)
13313 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13314 truncated lines if point is covered by a display string. (Bug#9524)
13316 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13318 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13319 (cons_to_x_long): New function.
13320 (lisp_data_to_selection_data): Use it. Correct the test for
13321 short-versus-long data; it was negated. Break out of vector
13322 loop, for efficiency, when a long datum is discovered.
13324 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13326 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

13347 * composite.c (composition_update_it, get_composition_id):
13348 * xdisp.c (get_next_display_element)
13349 (fill_composite_glyph_string): Add comments about special meaning
13350 of TAB characters in a composition.
13352 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13354 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13355 This occurs when processing a multibyte format.
13356 Problem reported by Wolfgang Jenker.
13358 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13360 * xdisp.c (try_cursor_movement): Only check for exact match if
13361 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13363 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13365 Remove unused external symbols.
13366 * dispextern.h (calc_pixel_width_or_height): Remove decl.

13373 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13375 * xselect.c: Use signed conversions more consistently (Bug#9498).
13376 (selection_data_to_lisp_data): Assume incoming selection data are
13377 signed integers, not unsigned. This is to be consistent with
13378 outgoing selection data, which was modified to use signed integers
13379 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13380 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13381 expects long, not unsigned long.

13408 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13409 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13411 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13413 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13414 value for non-existent files.
13416 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13418 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13419 set its "size" to -1. This will set the modtime_size field of
13420 the corresponding buffer to -1, which is what
13421 verify-visited-file-modtime expects for files that do not exist.
13424 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13426 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13428 * lisp.h: ... from here. push_key_description is no longer
13429 defined in keyboard.c, so its declaration should not be in
13430 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13431 logically belongs with push_key_description.
13433 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13435 * buffer.h: Include <sys/types.h> instead of <time.h>.
13436 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13437 Problem reported by Herbert J. Skuhra.
13439 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13441 * xml.c (parse_region): Make the parsing work for
13442 non-comment-starting XML files again (bug#9144).
13444 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13446 * image.c (gif_load): Fix calculation of bottom and right corner.
13449 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13451 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13452 redisplay in small windows.
13454 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13456 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13458 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13460 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13461 Operate on live windows only.
13463 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13465 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13467 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13469 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13470 only under bidi iteration.
13472 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13474 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13476 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13478 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13479 Without this fix, the command to link temacs failed due to an
13480 undefined symbol __builtin_isnan. This is because
13481 /usr/include/iso/math_c99.h #defines isnan(x) to
13482 __builtin_isnan(x), but the bundled gcc, which identifies itself
13483 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13485 * floatfns.c (isnan): #undef, and then #define to a clone of
13487 (Fisnan): Always define, since it's always available now.
13488 (syms_of_floatfns): Always define isnan at the Lisp level.
13490 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13492 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13494 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13496 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13497 The previous code assumed that file offsets (off_t values) fit in
13498 EMACS_INT variables, which is not true on typical 32-bit hosts.
13499 The code messed up by falsely reporting buffer overflow in cases
13500 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13501 when "big" contains more than 2**29 bytes, even though this
13502 inserts just one byte and does not overflow the buffer.
13503 (Finsert_file_contents): Store file offsets as off_t
13504 values, not as EMACS_INT values. Check for overflow when
13505 converting between EMACS_INT and off_t. When checking for
13506 buffer overflow or for overlap, take the offsets into account.
13507 Don't use EMACS_INT for small values where int suffices.
13508 When checking for overlap, fix a typo: ZV was used where
13509 ZV_BYTE was intended.
13510 (Fwrite_region): Don't assume off_t fits into 'long'.
13511 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13513 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13515 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13517 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13519 sprintf-related integer and memory overflow issues (Bug#9412).
13521 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13522 (esprintf, exprintf, evxprintf): New functions.
13523 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13524 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13525 (modify_event_symbol): Do not assume that the length of
13526 name_alist_or_stem is safe to alloca and fits in int.
13527 (Fexecute_extended_command): Likewise for function name and binding.
13528 (Frecursion_depth): Wrap around reliably on integer overflow.
13529 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13530 since some callers pass EMACS_INT values.
13531 (Fsingle_key_description): Don't crash if symbol name contains more
13532 than MAX_ALLOCA bytes.
13533 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13534 (get_minibuffer): Arg is now EMACS_INT, not int.
13535 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13536 (esprintf, exprintf, evxprintf): New decls.
13537 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13539 * dbusbind.c (signature_cat): New function.
13540 (xd_signature, Fdbus_register_signal):
13541 Do not overrun buffer; instead, report string overflow.
13543 * dispnew.c (add_window_display_history): Don't overrun buffer.
13544 Truncate instead; this is OK since it's just a log.
13546 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13547 even if the time zone offset is outlandishly large.
13548 Don't mishandle offset == INT_MIN.
13550 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13551 when creating daemon; the previous buffer-overflow check was incorrect.
13553 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13554 which has the guts of the old verror function.
13556 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13557 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13559 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13560 (font_unparse_xlfd): Don't blindly alloca long strings.
13561 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13562 fits in int, when using sprintf. Use single snprintf to count
13563 length of string rather than counting it via multiple sprintfs;
13564 that's simpler and more reliable.
13565 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13566 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13567 sprintf, in case result does not fit in int.
13569 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13570 (fontset_from_font): Print it.
13572 * frame.c (tty_frame_count): Now printmax_t, not int.
13573 (make_terminal_frame, set_term_frame_name): Print it.
13574 (x_report_frame_params): In X, window IDs are unsigned long,
13575 not signed long, so print them as unsigned.
13576 (validate_x_resource_name): Check for implausibly long names,
13577 and don't assume name length fits in 'int'.
13578 (x_get_resource_string): Don't blindly alloca invocation name;
13579 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13582 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13583 (xg_check_special_colors, xg_set_geometry):
13584 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13586 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13587 Use esprintf, not sprintf, in case result does not fit in int.
13589 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13590 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13591 it as a large positive number.
13592 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13593 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13595 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13596 in case result does not fit in int.
13598 * print.c (float_to_string): Detect width overflow more reliably.
13599 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13600 buffer overrun. Don't assume list length fits in 'int'. Treat
13601 print length of 0 as 0, not as infinity; to be consistent with other
13602 uses of print length in this function. Don't overflow print length
13603 index. Don't assume hash table size fits in 'long', or that
13604 vectorlike size fits in 'unsigned long'.
13606 * process.c (make_process): Use printmax_t, not int, to format
13607 process-name gensyms.
13609 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13611 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13612 to avoid potential buffer overrun.
13614 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13615 if X resource line is longer than 512 bytes.
13617 * xfns.c (x_window): Make sprintf buffer a bit bigger
13618 to avoid potential buffer overrun.
13620 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13622 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13624 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13626 Integer overflow fixes for scrolling, etc.
13627 Without these, Emacs silently mishandles large integers sometimes.
13628 For example, "C-u 4294967297 M-x recenter" was treated as if
13629 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13631 * xdisp.c (try_window_id): Check Emacs fixnum range before
13632 converting to 'int'.
13634 * window.c (window_scroll_line_based, Frecenter):
13635 Check that an Emacs fixnum is in range before assigning it to 'int'.
13636 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13637 values converted from Emacs fixnums.
13638 (Frecenter): Don't wrap around a line count if it is out of 'int'
13639 range; instead, treat it as an extreme value.
13640 (Fset_window_configuration, compare_window_configurations):
13641 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13643 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13644 that can exceed INT_MAX. Check that EMACS_INT value is in range
13645 before assigning it to the (possibly-narrower) index.
13646 (match_limit): Don't assume that a fixnum can fit in 'int'.
13648 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13651 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13652 (Fvertical_motion): Don't wrap around LINES values that don't fit
13653 in 'int'. Instead, treat them as extreme values. This is good
13654 enough for windows, which can't have more than INT_MAX lines anyway.
13656 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13658 * Require libxml/parser.h to avoid compilation warning.
13660 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13662 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13663 since this reportedly can destroy thread storage.
13665 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13667 * syntax.c (find_defun_start): Update all cache variables if
13668 exiting early (Bug#9401).
13670 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13672 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13674 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13675 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13676 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13678 * term.c (tty_append_glyph): New function.
13679 (produce_stretch_glyph): Static function and its prototype deleted.
13681 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13684 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13686 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13687 when checking :margin (Bug#9390).
13688 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13689 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13690 so that the name doesn't mislead. All uses changed.
13692 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13694 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13697 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13699 * xdisp.c (move_it_to): Don't bail out early when reaching
13700 position beyond to_charpos, if we are scanning backwards.
13701 (move_it_vertically_backward): When DY == 0, make sure we get to
13702 the first character in the line after the newline.
13704 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13706 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13707 (ccl_driver): Do not generate an out-of-range pointer.
13708 (Fccl_execute_on_string): Remove unnecessary check for
13709 integer overflow, noted by Stefan Monnier in
13710 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13711 Remove a FIXME that didn't need fixing.
13712 Simplify the newly-introduced buffer reallocation code.
13714 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13716 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13718 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13720 Integer and memory overflow issues (Bug#9196).
13722 * doc.c (get_doc_string): Rework so that
13723 get_doc_string_buffer_size is the actual buffer size, rather than
13724 being 1 less than the actual buffer size; this makes xpalloc more
13727 * image.c (x_allocate_bitmap_record, cache_image):
13728 * xselect.c (Fx_register_dnd_atom):
13729 Simplify previous changes by using xpalloc.
13731 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13732 since either will do and ptrdiff_t is convenient with xpalloc.
13734 * charset.c (charset_table_size)
13735 (struct charset_sort_data.priority): Now ptrdiff_t.
13736 (charset_compare): Don't overflow if priorities differ greatly.
13737 (Fsort_charsets): Don't assume list length fits in int.
13738 Check for size-calculation overflow when allocating sort data.
13739 (syms_of_charset): Allocate an initial charset table that is
13740 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13742 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13744 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13745 The actual value is always <= INT_MAX, and leaving it unsigned made
13746 overflow checking harder.
13748 * dispextern.h (struct glyph_matrix.rows_allocated)
13749 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13750 with xpalloc. The values are still always <= INT_MAX.
13752 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13754 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13755 (SAFE_NALLOCA): New macro.
13757 * region-cache.c (struct boundary.pos, find_cache_boundary)
13758 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13759 (set_cache_region, invalidate_region_cache)
13760 (revalidate_region_cache, know_region_cache, region_cache_forward)
13761 (region_cache_backward, pp_cache):
13762 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13763 so that ptrdiff_t * can be passed to xpalloc.
13764 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13765 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13766 (pp_cache): Don't assume cache_len fits in int.
13767 * region-cache.h: Adjust extern decls to match.
13769 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13770 EMACS_INT, since either will do, for xpalloc.
13772 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13773 (xnmalloc, xnrealloc, xpalloc): New functions.
13775 * bidi.c (bidi_shelve_header_size): New constant.
13776 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13777 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13779 * bidi.c (bidi_cache_shrink):
13780 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13782 Don't update size of array until after memory allocation succeeds,
13783 because xmalloc/xrealloc may not return.
13784 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13785 now that we have proper integer overflow checking.
13786 (record_overlay_string, overlay_strings): Catch overflows when
13787 calculating size of overlay_str_buf.
13789 * callproc.c (Fcall_process): Check for size overflow when
13790 calculating size of args2.
13791 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13792 Normally we prefer signed values, but sticking with ptrdiff_t would
13793 require adding more-complicated checks.
13795 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13796 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13797 Redo buffer-overflow calculations to avoid integer overflow.
13798 Add a FIXME comment where memory seems to be over-allocated.
13800 * character.c (Fstring): Check for size-calculation overflow.
13802 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13803 unnecessary integer overflow. Check for size overflow.
13804 (encode_coding_object): Don't update size until xmalloc succeeds.
13806 * composite.c (get_composition_id): Check for overflow in glyph
13807 length calculations.
13809 Integer and memory overflow fixes for display code.
13810 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13811 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13812 (scrolling_window): Check for overflow in size calculations.
13813 (line_draw_cost, realloc_glyph_pool, add_row_entry):
13814 Don't assume glyph table len fits in int.
13815 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
13816 (row_table_size): Now ptrdiff_t, not int.
13817 (scrolling_window): Avoid overflow in size calculations.
13818 Don't update size until allocation succeeds.
13819 * fns.c (concat): Check for overflow in size calculations.
13820 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
13821 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
13822 (NEXT_ALMOST_PRIME_LIMIT): New constant.
13824 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13825 (get_doc_string): Check for size calculation overflow.
13826 Don't update size until allocation succeeds.
13827 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13828 EMACS_INT, where ptrdiff_t will do.
13829 (Fsubstitute_command_keys): Check for string overflow.
13831 * editfns.c (set_time_zone_rule): Don't assume environment length
13833 (message_length): Now ptrdiff_t, not int.
13834 (Fmessage_box): Don't update size until allocation succeeds.
13835 Don't assume message length fits in int.
13836 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13838 * emacs.c (main): Do not reallocate argv, since there is a null at
13839 the end that can be overwritten, and this way there's no need to
13840 worry about size-calculation overflow.
13841 (sort_args): Check for size-calculation overflow.
13843 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13845 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13847 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13848 (x_set_scroll_bar_width, x_figure_window_size):
13849 Check for integer overflow.
13850 (x_set_alpha): Do not assume XINT fits in int.
13852 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13853 This is for the members text_lines, text_cols, total_lines, total_cols,
13854 where the system imposes an 'int' limit.
13856 * fringe.c (Fdefine_fringe_bitmap):
13857 Don't update size until alloc works.

13863 Check for size-calculation overflow.
13864 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13865 do, as we prefer signed integers.

13921 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13922 for command line length. Do not attempt to address one before the
13923 beginning of an array, as that's not portable.
13925 * term.c (max_frame_lines): Remove; unused.

13953 Check for size calculation overflow.
13954 (cache_face): Treat size calculation overflows as if they were
13955 memory exhaustion (the usual treatment), rather than aborting.
13957 * xfns.c (x_encode_text, x_set_name_internal)
13958 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13959 sizes, since they can exceed INT_MAX in size. Check for size
13960 calculation overflow.

13963 (xg_select): Check for size calculation overflow.
13964 Don't update size until alloc done.
13966 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13967 as sprintf is limited to int lengths.
13969 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13970 (X_LONG_MIN): New macros.
13971 Use them to make the following changes clearer.
13972 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13973 This change doesn't affect the value now, but it may help remind
13974 future maintainers not to raise the value too much later.
13975 (SELECTION_QUANTUM): Remove, replacing with ...
13976 (selection_quantum): ... new function, which avoids overflow.
13978 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13979 assumption that selection length fits in 'int'.

13996 Don't store size until memory allocation succeeds.
13997 (x_get_window_property): Plug memory leak on memory exhaustion.
13998 Don't double-block input; malloc is safe here. Don't assume 2**34
13999 - 4 fits in unsigned long. Add an xassert to check
14000 XGetWindowProperty overflow. Be more careful about overflow
14001 calculations, and distinguish size from memory overflow better.
14002 (receive_incremental_selection): When tracing, don't assume
14003 unsigned int is less than INT_MAX.
14004 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14008 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14009 result parameters unless successful. Rely on cons_to_unsigned
14010 to report problems with elements; the old code wasn't right anyway.
14011 (x_check_property_data): Check for int overflow; we cannot use
14012 a wider type due to X limits.

14045 * lisp.h (hash_lookup, hash_put):
14046 * minibuf.c (Ftest_completion):
14047 Use ptrdiff_t for hash table indexes, not int (which is too
14048 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14049 32-bit --with-wide-int hosts).
14051 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14052 Add a FIXME comment about memory leaks.

14060 with outlandish widths.
14061 * character.h (sanitize_tab_width): Rename from sanitize_width,
14062 now that we have two such functions. All uses changed.

14080 * xterm.c: Don't go over XClientMessageEvent limit.
14081 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14082 (x_send_scroll_bar_event): Likewise. Check that the size does not
14083 exceed limits imposed by XClientMessageEvent, as well as the usual
14084 ptrdiff_t and size_t limits.
14086 * keyboard.c: Overflow, signedness and related fixes.
14087 (make_lispy_movement): Use same integer type in forward decl
14088 that is used in the definition.
14089 (read_key_sequence, keyremap_step):
14090 Change bufsize argument back to int, undoing my 2011-03-30 change.
14091 We prefer signed types, and int is wide enough here.
14092 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14093 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14094 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14095 length, not size_t. Use ptrdiff_t for index, not int.
14096 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14097 possibility of integer overflow.
14099 Overflow, signedness and related fixes for images.

14121 (lookup_image): Remove unnecessary tests.
14122 (xbm_image_p): Locals are now of int, not EMACS_INT,
14123 since parse_image_check makes sure they fit into int.
14124 (png_load, gif_load, svg_load_image):
14125 Prefer int to unsigned where either will do.
14126 (tiff_handler): New function, combining the cores of the
14127 old tiff_error_handler and tiff_warning_handler.
14128 This function is rewritten to use vsnprintf and thereby avoid
14129 stack buffer overflows. It uses only the features of vsnprintf
14130 that are common to both POSIX and native Microsoft.
14131 (tiff_error_handler, tiff_warning_handler): Use it.
14132 (tiff_load, gif_load, imagemagick_load_image):
14133 Don't assume :index value fits in 'int'.
14134 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14135 (imagemagick_load_image): Check that crop parameters fit into
14136 the integer types that MagickCropImage accepts. Don't assume
14137 Vimagemagick_render_type has a nonnegative value. Don't assume
14138 size_t fits in 'long'.
14139 (gs_load): Use printmax_t to print the widest integers possible.

14153 (handle_single_display_spec): If the display spec is of the form
14154 `(space ...)', and specifies display in the text area, return 2
14156 (try_cursor_movement): Check for the need to scroll more
14157 accurately, and prefer exact match for point under bidi.
14158 Don't advance `row' beyond the last row of the window.

14176 buffers, return left-to-right.
14177 (set_cursor_from_row): Consider candidate row a win if its glyph
14178 represents a newline and point is on that newline. Fixes cursor
14179 positioning on the newline at EOL of R2L text within L2R
14180 paragraph, and vice versa.
14181 (try_cursor_movement): Check continued rows, in addition to
14182 continuation rows. Fixes unwarranted scroll when point enters a
14183 continued line of R2L text within an L2R paragraph, or vice versa.
14184 (cursor_row_p): Consider the case of point being equal to
14185 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14186 from the end of a short line to the beginning of a continued line
14187 of R2L text within L2R paragraph.
14188 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

14211 * xdisp.c (redisplay_window): When computing centering_position,
14212 account for the height of the header line. (Bug#8874)
14214 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14215 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14216 candidate is selected by the mouse, and that candidate has a
14217 composed character under the mouse.
14219 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14220 coordinates reported by pos-visible-in-window-p for a composed
14221 character in column zero.
14223 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14227 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14229 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14230 consider it a hit if to_charpos is anywhere in the range of the
14231 composed buffer positions.
14233 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14235 * image.c (gif_load): Don't assume that each subimage has the same
14236 dimensions as the base image. Handle disposal method that is
14237 "undefined" by the gif spec (Bug#9335).
14239 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14241 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14246 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14247 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14248 from an Org mode buffer to a Speedbar frame.
14250 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14251 a composition, take its buffer position from IT->cmp_it.charpos.
14252 Fixes cursor positioning at the beginning of a line that begins
14253 with a composed character.
14255 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14257 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14258 character bidirectional type, use STRONG_L instead. Fixes crashes
14259 in a buffer produced by `describe-categories'.
14261 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14262 members before the level stack, so they would be saved and
14263 restored when copying iterator state. Fixes incorrect reordering
14264 around TABs covered by display properties.
14266 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14268 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14292 Fix memory allocation problems in Cygwin build (Bug#9273).
14294 * unexcw.c ( __malloc_initialized): Declare external variable.
14295 (fixup_executable): Force the dumped emacs to reinitialize malloc.
14297 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
14299 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
14301 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
14302 in the static heap.
14303 [CYGWIN] (special_realloc): New function.
14304 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
14305 requests to realloc storage in the static heap.
14307 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
14309 * bidi.c (bidi_initialize): Remove unused local.
14311 2011-08-15 Eli Zaretskii <eliz@gnu.org>
14314 * biditype.h: Remove file.
14315 * makefile.w32-in ($(BLD)/bidi.$(O)):
14316 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
14318 * dispextern.h: Fix a typo in the comment to bidi_type_t.
14320 * chartab.c: Improve commentary for the uniprop_table API.
14322 * bidi.c (bidi_paragraph_init): Support zero value of
14323 bidi_ignore_explicit_marks_for_paragraph_level.
14324 (bidi_initialize): Use uniprop_table instead of including
14325 biditype.h and bidimirror.h.
14327 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
14328 coordinates of the iterator when restoring from ppos_it.
14331 2011-08-14 Kenichi Handa <handa@m17n.org>
14333 * process.c (create_process): Call setup_process_coding_systems
14334 after the pid of the process is set to -1 (Bug#8162).
14336 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14338 * xdisp.c (move_it_in_display_line_to): Don't invoke
14339 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14340 ppos_it. Fixes vertical cursor motion when line beginning is
14341 covered by an image. (Bug#9296)
14343 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14345 * nsterm.h (ns_run_ascript): Declare.
14346 (NSAPP_DATA2_RUNASSCRIPT): Define.
14348 * nsfns.m (as_script, as_result, as_status): New static variables.
14349 (ns_run_ascript): New function.
14350 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14351 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14352 the event loop. Get status from as_status (Bug#7276).
14354 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14355 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14356 the event loop (Bug#7276).
14358 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14360 * gnutls.c (QCgnutls_bootprop_priority)
14361 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14362 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14363 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14364 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14365 (QCgnutls_bootprop_verify_hostname_error)
14366 (QCgnutls_bootprop_callbacks_verify): Rename from
14367 Qgnutls_bootprop_..., all uses changed.
14369 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
14372 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
14374 * xfaces.c (Qframe_set_background_mode): Now static.
14375 * dispextern.h (Qframe_set_background_mode): Remove decl.
14377 * process.c (Fnetwork_interface_info): Declare local only if needed.
14379 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
14381 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14382 (Fnetwork_interface_list): Allocate in increments of bytes instead
14383 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14384 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14386 (struct ifflag_def): notrailers is smart on OSX.
14387 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14388 Get hardware address with getifaddrs if available.
14390 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14392 * xdisp.c (iterate_out_of_display_property): xassert that
14393 IT->position is set to within IT->object's boundaries. Break from
14394 the loop as soon as EOB is reached; avoids infloops in redisplay
14395 when IT->position is set up wrongly due to some bug.
14396 Set IT->current to match the bidi iterator unconditionally.
14397 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14398 entry. Force push_it to save on the stack the current
14399 buffer/string position, to be restored by pop_it. Fix flags in
14400 the iterator structure wrt the object coming from a display
14401 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14402 properties. (Bug#9284)
14404 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14406 * fontset.c (fontset_get_font_group): Add proper type checks.
14409 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14411 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
14412 and LC_VERSION_MIN_MACOSX.
14413 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
14414 (dump_it) [LC_FUNCTION_STARTS]: Use it.
14416 2011-08-08 Eli Zaretskii <eliz@gnu.org>
14418 * xdisp.c (forward_to_next_line_start): Allow to use the
14419 no-display-properties-and-no-overlays under bidi display.
14420 Set disp_pos in the bidi iterator to avoid searches for display
14421 properties and overlays.
14423 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14425 * editfns.c (Fset_time_zone_rule): Document relationship with the
14428 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
14429 the font entity extracted from the cache (Bug#8109).
14431 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14433 * composite.c (autocmp_chars): Don't reset point. That is done by
14434 restore_point_unwind (Bug#5984).
14436 2011-08-07 Juri Linkov <juri@jurta.org>
14438 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14439 to show the arg `TIME' instead of `TIMEVAL'.
14441 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14443 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14444 display property strides EOL and includes a newline, as in
14445 longlines-mode. (Bug#9254)
14446 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14447 word-wrap under bidirectional display. (Bug#9224)
14449 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14450 is non-zero, even if the data buffer is NULL. Fixes a crash in
14451 vertical-motion with longlines-mode. (Bug#9254)
14453 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14455 * bidi.c <bidi_cache_total_alloc>: Now static.
14456 (bidi_initialize): Initialize bidi_cache_total_alloc.
14458 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14461 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14462 amount allocated this far in `bidi_cache_total_alloc'.
14463 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14464 non-zero, only free the data buffer without restoring the cache
14465 contents. All callers changed.
14467 * dispextern.h (bidi_unshelve_cache): Update prototype.
14469 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14470 (move_it_in_display_line, move_it_to)
14471 (move_it_vertically_backward, move_it_by_lines): Replace the call
14472 to xfree to an equivalent call to bidi_unshelve_cache.
14473 (move_it_in_display_line_to): Fix logic of returning
14474 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14476 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14478 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14479 came from a string character with a `cursor' property. (Bug#9229)
14481 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14483 * Makefile.in (LIB_PTHREAD): New variable.
14484 (LIBES): Add LIB_PTHREAD (Bug#9216).
14486 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14487 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14489 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14491 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14493 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14495 * xterm.c (x_find_topmost_parent): New function.
14496 (x_set_frame_alpha): Find topmost parent window with
14497 x_find_topmost_parent and set the property there also (bug#9181).
14498 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14500 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14502 * callproc.c (Fcall_process): Avoid vfork clobbering
14503 the local vars buffer, coding_systems, current_dir.
14505 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14507 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14509 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14511 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14512 so that it is not optimized away.
14514 * xdisp.c (compute_display_string_pos): Remove unused local.
14516 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14518 Fix slow cursor motion and scrolling in large buffers with
14519 selective display, like Org Mode buffers. (Bug#9218)
14521 * dispextern.h (struct bidi_it): New member disp_prop_p.
14523 * xdisp.c: Remove one-slot cache of display string positions.
14524 (compute_display_string_pos): Accept an additional argument
14525 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14526 for a display string or property. If found, set DISP_PROP_P
14529 * bidi.c (bidi_fetch_char): Accept an additional argument
14530 DISP_PROP_P, and pass it to compute_display_string_pos.
14531 Only handle text covered by a display string if DISP_PROP_P is returned
14532 non-zero. All callers of bidi_fetch_char changed.
14534 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14536 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14538 2010-12-03 Don March <don@ohspite.net>
14540 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14541 last character M-[char] is translated to ESC [char] (bug#7541).
14543 2011-08-02 Kenichi Handa <handa@m17n.org>
14545 * lisp.h (uniprop_table): Extern it.
14547 * chartab.c (uniprop_table): Make it non-static.
14549 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14551 * xdisp.c (forward_to_next_line_start): Accept additional argument
14552 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14554 (reseat_at_next_visible_line_start): Use the bidi iterator state
14555 returned by forward_to_next_line_start to restore the state of
14556 it->bidi_it after backing up to previous newline. (Bug#9212)
14558 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14560 * regex.c (re_comp): Protoize.
14561 (re_exec): Fix return type.
14562 (regexec): Fix type of `ret'. (Bug#9203)
14564 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14566 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14567 This is needed if max-image-size is a floating-point number.
14569 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14571 * print.c (print_object): Print empty symbol as ##.
14573 * lread.c (read1): Read ## as empty symbol.
14575 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14577 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14578 setting frame foreground color (Bug#9175).
14579 (x_set_background_color): Likewise.
14581 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14582 contents (Bug#9176).
14583 (EmacsTooltip -init): Remove bezels and add shadows to
14586 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14587 or scroll bar (Bug#8470).
14589 * nsfont.m (nsfont_open): Remove assignment to voffset and
14590 unnecessary vars hshink, expand, hd, full_height, min_height.
14591 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14593 * nsterm.h (nsfont_info): Remove voffset field.
14595 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14597 Implement strike-through and overline on NextStep (Bug#8863).
14599 * nsfont.m (nsfont_open): Use underline position provided by font,
14600 instead of hard-coded value of 2.
14601 (nsfont_draw): Call ns_draw_text_decoration instead.
14603 * nsterm.h: Add declaration for ns_draw_text_decoration.
14605 * nsterm.m (ns_draw_text_decoration): New function for drawing
14606 underline, overline, and strike-through.
14607 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14608 ns_draw_text_decoration. Change treatment of cursor drawing to
14609 accommodate underlining, etc.
14611 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14613 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14616 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14618 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14619 Without this fix, if a signal arrives just after memory fills up,
14620 'malloc' might be invoked reentrantly.
14622 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14623 In other words, assume that every image size is allowed, on non-X
14624 hosts. This assumption is probably wrong, but it lets Emacs compile.
14626 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14628 * regex.c (re_iswctype): Convert return values to boolean.
14630 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14632 * xdisp.c (compute_display_string_pos): Don't use cached display
14633 string position if the buffer had its restriction changed.
14636 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14638 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14640 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14642 Integer signedness and overflow and related fixes. (Bug#9079)
14644 * bidi.c: Integer size and overflow fixes.
14645 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14646 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14647 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14648 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14649 (bidi_find_other_level_edge):
14650 Use ptrdiff_t instead of EMACS_INT where either will do.
14651 This works better on 32-bit hosts configured --with-wide-int.
14652 (bidi_cache_ensure_space): Check for size-calculation overflow.
14653 Use % rather than repeated addition, for better worst-case speed.
14654 Don't set bidi_cache_size until after xrealloc returns, because it
14656 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14657 (bidi_cache_ensure_space): Also check that the bidi cache size
14658 does not exceed that of the largest Lisp string or buffer. See Eli
14659 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14661 * alloc.c (__malloc_size_t): Remove.
14662 All uses replaced by size_t. See Andreas Schwab's note
14663 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14665 * image.c: Improve checking for integer overflow.
14666 (check_image_size): Assume that f is nonnull, since
14667 it is always nonnull in practice. This is one less thing to
14668 worry about when checking for integer overflow later.
14669 (x_check_image_size): New function, which checks for integer
14670 overflow issues inside X.
14671 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14672 This removes the need for a memory_full check.
14673 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14674 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14675 (xbm_read_bitmap_data): Change locals back to 'int', since
14676 their values must fit in 'int'.
14677 (xpm_load_image, png_load, tiff_load):
14678 Invoke x_create_x_image_and_pixmap earlier,
14679 to avoid much needless work if the image is too large.
14680 (tiff_load): Treat overly large images as if
14681 x_create_x_image_and_pixmap failed, not as malloc failures.
14682 (gs_load): Use x_check_image_size.
14684 * gtkutil.c: Omit integer casts.
14685 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14686 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14688 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14690 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14691 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14692 would wrongly return t on a 64-bit host.
14694 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14695 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14696 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14697 and therefore cause GCC to emit a bogus diagnostic in some cases.
14699 * image.c: Integer signedness and overflow and related fixes.
14700 This is not an exhaustive set of fixes, but it's time to
14701 record what I've got.
14702 (lookup_pixel_color, check_image_size): Remove redundant decls.
14703 (check_image_size): Don't assume that arbitrary EMACS_INT values
14704 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14705 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14706 (tiff_load, imagemagick_load_image):
14707 Check for overflow in size calculations.
14708 (x_create_x_image_and_pixmap): Remove unnecessary test for
14709 xmalloc returning NULL; that can't happen.
14710 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14711 (xpm_color_bucket): Use better integer hashing function.
14712 (xpm_cache_color): Don't possibly over-allocate memory.
14713 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14714 (gif_memory_source):
14715 Use ptrdiff_t, not int or size_t, to record sizes.
14716 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14717 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14718 either works, as we prefer signed integers.
14719 (tiff_read_from_memory, tiff_write_from_memory):
14720 Return tsize_t, not size_t, since that's what the TIFF API wants.
14721 (tiff_read_from_memory): Don't fail simply because the read would
14722 go past EOF; instead, return a short read.
14723 (tiff_load): Omit no-longer-needed casts.
14724 (Fimagemagick_types): Don't assume size fits into 'int'.
14726 Improve hashing quality when configured --with-wide-int.
14727 * fns.c (hash_string): New function, taken from sxhash_string.
14728 Do not discard information about ASCII character case; this
14729 discarding is no longer needed.
14730 (sxhash-string): Use it. Change sig to match it. Caller changed.
14731 * lisp.h: Declare it.
14732 * lread.c (hash_string): Remove, since we now use fns.c's version.
14733 The fns.c version returns a wider integer if --with-wide-int is
14734 specified, so this should help the quality of the hashing a bit.
14736 * emacs.c: Integer overflow minor fix.
14737 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14738 Define only if GNU_LINUX.
14739 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14741 * dispnew.c: Integer signedness and overflow fixes.
14742 Remove unnecessary forward decls, that were a maintenance hassle.
14743 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14745 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14746 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14747 (prepare_desired_row, line_draw_cost):
14748 Use int, not unsigned, where either works.
14749 (save_current_matrix, restore_current_matrix):
14750 Use ptrdiff_t, not size_t, where either works.
14751 (init_display): Check for overflow more accurately, and without
14752 relying on undefined behavior.
14754 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14755 Remove, replacing with the new symbols in lisp.h. All uses changed.
14756 * fileio.c (make_temp_name):
14757 * filelock.c (lock_file_1, lock_file):
14758 * xdisp.c (message_dolog):
14759 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14760 Use pMd etc. instead.
14761 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14762 replacing the pWIDE etc. symbols removed from editfns.c.
14764 * keyboard.h (num_input_events): Now uintmax_t.
14765 This is (very slightly) less likely to mess up due to wraparound.
14768 * buffer.c: Integer signedness fixes.
14769 (alloc_buffer_text, enlarge_buffer_text):
14770 Use ptrdiff_t rather than size_t when either will do, as we prefer
14773 * alloc.c: Integer signedness and overflow fixes.
14774 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14775 (__malloc_size_t): Default to size_t, not to int.
14776 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14777 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14778 Prefer ptrdiff_t to size_t when either would do, as we prefer
14780 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14781 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14782 Now const. Initialize with values that are in range even if char
14784 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14785 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14786 These functions do the right thing with sizes > 2**32.
14787 (check_depth): Now ptrdiff_t, not int.
14788 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14789 Adjust to new way of storing sizes. Check for size overflow bugs
14791 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14792 slightly wrong anyway, as it missed one instance of
14793 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14794 (refill_memory_reserve): Omit needless cast to size_t.
14795 (mark_object_loop_halt): Mark as externally visible.
14797 * xselect.c: Integer signedness and overflow fixes.
14798 (Fx_register_dnd_atom, x_handle_dnd_message):
14799 Use ptrdiff_t, not size_t, since we prefer signed.
14800 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14801 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14802 x_dnd_atoms_size and x_dnd_atoms_length.
14804 * doprnt.c: Prefer signed to unsigned when either works.
14806 * doprnt.c (doprnt):
14808 * xdisp.c (vmessage):
14809 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14810 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14811 prefer signed arithmetic to avoid comparison confusion.
14812 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14813 but is a bit tricky.
14815 Assume freestanding C89 headers, string.h, stdlib.h.
14816 * data.c, doprnt.c, floatfns.c, print.c:
14817 Include float.h unconditionally.
14818 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14819 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14820 * regex.c: Likewise for stddef.h, string.h.
14821 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14822 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14823 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14824 (STDC_HEADERS): Remove obsolete defines.
14825 * sysdep.c: Include limits.h unconditionally.
14827 Assume support for memcmp, memcpy, memmove, memset.
14828 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14829 * regex.c (memcmp, memcpy):
14830 Remove; we assume C89 now.
14832 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14833 (__malloc_safe_bcopy): Remove; no longer needed.
14835 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14836 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14837 well either way, and we prefer signed to unsigned.
14839 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14841 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14842 closes the connection while we're reading (bug#9182).
14844 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14846 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14847 are specified (Bug#9168).
14849 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14851 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14852 Found by GCC static checking and --with-wide-int on a 32-bit host.
14854 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14856 * xdisp.c (compute_display_string_pos): Fix logic of caching
14857 previous display string position. Initialize cached_prev_pos to
14858 -1. Fixes slow-down at the beginning of a buffer.
14860 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14862 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14863 for attrs[LFACE_FONTSET_INDEX].
14865 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14867 * xml.c (parse_region): Remove unused local
14868 that was recently introduced.
14870 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14872 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14873 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14875 * xdisp.c (move_it_in_display_line_to): Record the best matching
14876 position for TO_CHARPOS while scanning the line, and restore it on
14877 exit if none of the characters scanned was an exact match.
14878 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14879 when exact match is impossible due to invisible text, and the
14880 lines are truncated.
14882 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14884 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14887 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14889 Fix a significant slow-down of cursor motion with C-n, C-p,
14890 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14891 auto-repeat under bidi redisplay in fontified buffers.
14892 * xdisp.c (compute_stop_pos_backwards): New function.
14893 (next_element_from_buffer): Call compute_stop_pos_backwards to
14894 find a suitable prev_stop when we find ourselves before
14896 (reseat): Don't look for prev_stop, as that could mean a very long
14898 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14899 <cached_disp_overlay_modiff>: Cache for last found display string
14901 (compute_display_string_pos): Return the cached position if asked
14902 about the same buffer in the same area of character positions, and
14903 the buffer wasn't changed since the time the display string
14904 position was cached.
14906 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14908 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14909 is an integer, which is important for empty lines. (Bug#9149)
14911 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14913 * frame.c (Fmodify_frame_parameters): In tty case, update the
14914 default face if necessary (Bug#4238).
14916 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14918 * editfns.c (Fstring_to_char): No need to explain what a character
14919 is in the docstring (Bug#6576).
14921 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14923 * xml.c (parse_region): Make sure we always return a tree.
14925 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14927 * xml.c (parse_region): If a document contains only comments,
14930 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14932 * xml.c (make_dom): Return comments, too.
14934 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14937 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14938 and the surrounding thread.
14939 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14940 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14941 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14943 * s/openbsd.h (BROKEN_SIGIO): Define.
14944 * unexelf.c (unexec) [__OpenBSD__]:
14945 Don't update the .mdebug section of the Alpha COFF symbol table.
14947 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14949 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14952 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14954 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14955 This fixes some race conditions on the permissions of any newly
14958 * alloc.c (valid_pointer_p): Use pipe, not open.
14959 This fixes some permissions issues when debugging.
14961 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14962 If fchown fails to set both uid and gid, try to set just gid,
14963 as that is sometimes allowed. Adjust the file's mode to eliminate
14964 setuid or setgid bits that are inappropriate if fchown fails.
14966 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14968 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14969 to compare Lisp_Objects.
14970 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14971 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14972 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14974 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14976 * lread.c (read_integer): Unread even EOF character.
14977 (read1): Likewise. Properly record start position of symbol.
14979 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14980 symbol character follows.
14982 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14984 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14985 This works around a problem with the previous change to Fcopy_file.
14986 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14987 and without this change, GCC might complain about discarding
14988 fchown's return value.
14990 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14992 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14994 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14996 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14998 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15000 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15001 it's used from the C level.
15003 * process.c: Use the same condition for POLL_FOR_INPUT in both
15004 keyboard.c and process.c (bug#1858).
15006 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15008 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15009 (Fgnutls_boot): Use it.
15011 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15013 * doc.c (Fsubstitute_command_keys): Revert last change.
15015 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15017 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15018 quotes the next character, and doesn't affect other longer
15019 sequences (bug#8935).
15021 * lread.c (syms_of_lread): Clarify that is isn't only
15022 `eval-buffer' and `eval-defun' that's affected by
15023 `lexical-binding' (bug#8460).
15025 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15027 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15028 bidi redisplay when a line includes both an image and is truncated.
15030 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15032 Fix minor problems found by static checking.
15033 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15034 (elsz): Now a signed constant, not a size_t var. We prefer signed
15035 types to unsigned, to avoid integer comparison confusion. Without
15036 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15037 "cannot optimize loop, the loop counter may overflow", a symptom
15039 * indent.c (Fvertical_motion): Mark locals as initialized.
15040 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15042 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15044 * search.c (Fre_search_backward): Mention `case-fold-search' in
15045 all the re_search_* functions (bug#8138).
15047 * keyboard.c (Fopen_dribble_file): Document when the file is

15058 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15059 (reseat_to_string): Initialize bidi_it->string.s and
15060 bidi_it->string.schars.
15061 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15062 NULL (avoids a crash in bidi_paragraph_init).
15063 Initialize itb.string.lstring.
15064 (init_iterator): Call bidi_init_it only of a valid
15065 buffer position was specified. Initialize paragraph_embedding to
15067 (reseat_to_string): Initialize the bidi iterator.
15068 (display_string): If we need to ignore text properties of
15069 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15070 original value of -1 will not work with bidi.)
15071 (compute_display_string_pos): First arg is now struct
15072 `text_pos *'; all callers changed. Support display properties on
15074 (compute_display_string_end): Support display properties on Lisp
15076 (init_iterator, reseat_1, reseat_to_string): Initialize the
15077 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15078 when iterating on a string not from display properties).
15079 (compute_display_string_pos, compute_display_string_end):
15080 Fix calculation of the object to scan. Fixes an error when using
15082 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15083 base_level_stop; instead, set base_level_stop to BEGV.
15084 Fixes crashes in vertical-motion.
15085 (next_element_from_buffer): Improve commentary for when
15086 the iterator is before prev_stop.
15087 (init_iterator): Initialize bidi_p from the default value of
15088 bidi-display-reordering, not from buffer-local value. Use the
15089 buffer-local value only if initializing for buffer iteration.
15090 (handle_invisible_prop): Support invisible properties on strings
15091 that are being bidi-reordered.
15092 (set_iterator_to_next): Support bidi reordering of C strings and
15094 (next_element_from_string): Support bidi reordering of Lisp
15096 (handle_stop_backwards): Support Lisp strings as well.
15097 (display_string): Support display of R2L glyph rows.
15098 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15099 (init_iterator): Don't initialize it->bidi_p for strings
15101 (reseat_to_string): Initialize it->bidi_p for strings here.
15102 (next_element_from_string, next_element_from_c_string)
15103 (next_element_from_buffer): Add xassert's for correspondence
15104 between IT's object being iterated and it->bidi_it.string
15106 (face_before_or_after_it_pos): Support bidi iteration.
15107 (next_element_from_c_string): Handle the case of the first string
15108 character that is not the first one in the visual order.
15109 (get_visually_first_element): New function, refactored from common
15110 parts of next_element_from_buffer, next_element_from_string, and
15111 next_element_from_c_string.
15112 (tool_bar_lines_needed, redisplay_tool_bar)
15113 (display_menu_bar): Force left-to-right direction. Add a FIXME
15114 comment for making that be controlled by a user option.
15115 (push_it, pop_it): Save and restore the state of the
15116 bidi iterator. Save and restore the bidi_p flag.
15117 (pop_it): Iterate out of display property for string iteration as
15119 (iterate_out_of_display_property): Support iteration over strings.
15120 (handle_single_display_spec): Set up it->bidi_it for iteration
15121 over a display string, and call bidi_init_it.
15122 (handle_single_display_spec, next_overlay_string)
15123 (get_overlay_strings_1, push_display_prop): Set up the bidi
15124 iterator for displaying display or overlay strings.
15125 (forward_to_next_line_start): Don't use the shortcut if
15127 (back_to_previous_visible_line_start): If handle_display_prop
15128 pushed the iterator stack, restore the internal state of the bidi
15129 iterator by calling bidi_pop_it same number of times.
15130 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15131 and we are bidi-iterating, don't decrement the iterator position;
15132 instead, set the first_elt flag in the bidi iterator, to produce
15134 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15135 (push_display_prop): xassert that we are iterating a buffer.
15136 (push_it, pop_it): Save and restore paragraph_embedding member.
15137 (handle_single_display_spec, next_overlay_string)
15138 (get_overlay_strings_1, reseat_1, reseat_to_string)
15139 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15140 correctly. Don't assume unibyte strings are not bidi-reordered.
15141 (compute_display_string_pos)
15142 (compute_display_string_end): Fix handling the case of C string.
15143 (push_it, pop_it): Save and restore from_disp_prop_p.
15144 (handle_single_display_spec, push_display_prop): Set the
15145 from_disp_prop_p flag.
15146 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
15147 (pop_it): Call iterate_out_of_display_property only if we are
15148 popping after iteration over a string that came from a display
15149 property. Fix a typo in popping stretch info. Add an assertion
15150 for verifying that the iterator position is in sync with the bidi
15152 (handle_single_display_spec, get_overlay_strings_1)
15153 (push_display_prop): Fix initialization of paragraph direction for
15154 string when that of the parent object is not yet determined.
15155 (reseat_1): Call bidi_init_it to resync the bidi
15156 iterator with IT's position. (Bug#7616)
15157 (find_row_edges): If ROW->start.pos gives position
15158 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
15159 (handle_stop, back_to_previous_visible_line_start, reseat_1):
15160 Reset the from_disp_prop_p flag.
15161 (SAVE_IT, RESTORE_IT): New macros.
15162 (pos_visible_p, face_before_or_after_it_pos)
15163 (back_to_previous_visible_line_start)
15164 (move_it_in_display_line_to, move_it_in_display_line)
15165 (move_it_to, move_it_vertically_backward, move_it_by_lines)
15166 (try_scrolling, redisplay_window, display_line): Use them when
15167 saving a temporary copy of the iterator and restoring it back.
15168 (back_to_previous_visible_line_start, reseat_1)
15169 (init_iterator): Empty the bidi cache "stack".
15170 (move_it_in_display_line_to): If iterator ended up at
15171 EOL, but we never saw any buffer positions smaller than
15172 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
15173 motion in bidi-reordered lines.
15174 (move_it_in_display_line_to): Record prev_method and prev_pos
15175 immediately before the call to set_iterator_to_next. Fixes cursor
15176 motion in bidi-reordered lines with stretch glyphs and strings
15177 displayed in margins. (Bug#8133) (Bug#8867)
15178 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
15180 (pos_visible_p): Support positions in bidi-reordered lines.
15181 Save and restore bidi cache.

15606 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15607 subseconds part to the entropy, as that's a bit more random.
15608 Prefer signed to unsigned, since the signedness doesn't matter and
15609 in general we prefer signed. When given a limit, use a
15610 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15611 latter isn't right if USE_2_TAGS_FOR_INTS.
15612 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15613 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15639 * fns.c (Frequire): Remove the mention of the .gz files, since
15640 that's installation-specific, but keep the mention of

15758 * eval.c (struct backtrace): Simplify and port the data structure.
15759 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15760 signed bit field, as this assumption is not portable and it makes
15761 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15762 "char debug_on_exit : 1" as this is not portable either; instead,
15763 use the portable "unsigned int debug_on_exit : 1". Remove unused
15764 member evalargs. Remove obsolete comments about cc bombing out.
15766 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

15838 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15839 and use min_width/height from frames size_hint to set
15840 min_width/height (Bug#8919).

15954 (read1): Check for integer overflow in radices, and in
15955 read-circle numbers.

15957 (Fload, openp, read_buffer_size, read1)
15958 (substitute_object_recurse, read_vector, read_list, map_obarray):

15984 * dispnew.c (flush_stdout):
15985 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15986 Mark as externally visible.
15987 * dispnew.c (check_window_matrix_pointers): Now static.

15999 on undefined behavior with wrong number of arguments.
16000 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16001 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16002 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16003 since we're not interested in debugging glyphs with old libraries.
16004 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16005 GCC 4.6.0's static checking.
16007 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

16041 Use ptrdiff_t, not int, for sizes.
16042 (overlays_at, overlays_in): Check for size-calculation overflow.
16044 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16046 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16047 (x_session_initialize): Do not assume string length fits in int.
16049 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16050 This is unlikely, but can occur if DPI is outlandish.
16052 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16053 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16055 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16056 * xrdb.c (magic_file_p, search_magic_path):
16057 Omit last arg SUFFIX; it was always 0. All callers changed.
16058 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16060 * xfont.c (xfont_match): Avoid need for strlen.
16062 * xfns.c: Don't assume strlen fits in int.
16063 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16065 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16066 not unsigned long, as we prefer signed integers. All callers changed.
16067 Detect integer overflow in repeat count.
16068 (message_dolog): Don't assume print length fits in 39 bytes.
16069 (display_mode_element): Don't assume strlen fits in int.
16071 * termcap.c: Don't assume sizes fit in int and never overflow.
16072 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16073 (gobble_line): Check for size-calculation overflow.
16075 * minibuf.c (Fread_buffer):
16076 * lread.c (intern, intern_c_string):
16077 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16078 Don't assume string length fits in int.
16080 * keyboard.c (parse_tool_bar_item):
16081 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16083 * font.c: Don't assume string length fits in int.
16084 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16085 Use ptrdiff_t, not int.
16086 (font_intern_prop): Don't assume string length fits in int.
16087 Don't assume integer property fits in fixnum.
16088 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16090 * filelock.c: Fix some buffer overrun and integer overflow issues.
16091 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16092 Reformulate so as not to need the command string.
16093 Invoke gzip -cd rather than gunzip, as it's more portable.
16094 (lock_info_type, lock_file_1, lock_file):
16095 Don't assume pid_t and time_t fit in unsigned long.
16096 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16097 (current_lock_owner): Prefer signed type for sizes.
16098 Use memcpy, not strncpy, where memcpy is what is really wanted.
16099 Don't assume (via atoi) that time_t and pid_t fit in int.
16100 Check for time_t and/or pid_t out of range, e.g., via a network share.
16101 Don't alloca where an auto var works fine.
16103 * fileio.c: Fix some integer overflow issues.
16104 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16105 Don't assume string length fits in int.
16106 (directory_file_name): Don't assume string length fits in long.
16107 (make_temp_name): Don't assume pid fits in int, or that its print
16108 length is less than 20.
16110 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16112 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16114 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16116 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16117 We prefer signed integers, even for size calculations.
16119 * emacs.c: Don't assume string length fits in 'int'.
16120 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16121 (main): Don't invoke strlen when not needed.
16123 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16124 (XD_DEBUG_MESSAGE): Don't waste a byte.
16126 * callproc.c (getenv_internal_1, getenv_internal)
16127 (Fgetenv_internal):
16128 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16130 * lread.c (invalid_syntax): Omit length argument.
16131 All uses changed. This doesn't fix a bug, but it simplifies the
16132 code away from its former Hollerith-constant appearance, and it's
16133 one less 'int' to worry about when looking at integer-overflow issues.
16134 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16136 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16137 This didn't break anything, but it didn't help either.
16138 It's confusing to put a bogus integer in a place where the actual
16139 value does not matter.
16140 (LIST_END_P): Remove unused macro and its bogus comment.
16141 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16143 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16144 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16146 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16147 We prefer signed types, and the value cannot exceed the EMACS_INT
16148 range anyway (because otherwise the length would not be representable).
16149 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16150 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16151 This avoids a GCC warning when WIDE_EMACS_INT.
16153 * indent.c (sane_tab_width): New function.
16154 (current_column, scan_for_column, Findent_to, position_indentation)
16155 (compute_motion): Use it. This is just for clarity.
16156 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16158 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16160 * lisp.h (lint_assume): New macro.
16161 * composite.c (composition_gstring_put_cache):
16162 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16164 * editfns.c, insdel.c:
16165 Omit unnecessary forward decls, to simplify future changes.
16167 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16169 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16171 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16172 Use much-faster test for byte-length change.
16173 Don't assume string byte-length fits in 'int'.
16174 Check that character arg fits in 'int'.
16175 (mapcar1): Declare byte as byte, for clarity.
16177 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16179 * fns.c (concat): Catch string overflow earlier.
16180 Do not rely on integer wraparound.
16182 * dispextern.h (struct it.overlay_strings_charpos)
16183 (struct it.selective): Now EMACS_INT, not int.
16184 * xdisp.c (forward_to_next_line_start)
16185 (back_to_previous_visible_line_start)
16186 (reseat_at_next_visible_line_start, next_element_from_buffer):
16187 Don't arbitrarily truncate the value of 'selective' to int.
16189 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16191 * composite.c: Don't truncate sizes to 'int'.
16192 (composition_gstring_p, composition_reseat_it)
16193 (composition_adjust_point): Use EMACS_INT, not int.
16194 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16195 not EMACS_UINT, for indexes.
16197 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16199 * buffer.c: Include <verify.h>.
16200 (struct sortvec.priority, struct sortstr.priority):
16201 Now EMACS_INT, not int.
16202 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16203 (struct sortstr.size, record_overlay_string)
16204 (struct sortstrlist.size, struct sortlist.used):
16205 Don't truncate size to int.
16206 (record_overlay_string): Check for size-calculation overflow.
16207 (init_buffer_once): Check at compile-time, not run-time.
16209 2011-06-22 Jim Meyering <meyering@redhat.com>
16211 Don't leak an XBM-image-sized buffer
16212 * image.c (xbm_load): Free the image buffer after using it.
16214 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16217 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16218 that Sun C diagnosed.
16219 * fns.c (secure_hash): Fix pointer signedness issue.
16220 * intervals.c (static_offset_intervals): New function.
16221 (offset_intervals): Use it.
16223 2011-06-21 Leo Liu <sdl.web@gmail.com>
16226 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16229 * fns.c (secure_hash): Rename from crypto_hash_function and change
16230 the first arg to accept symbols.
16231 (Fsecure_hash): New primitive.
16232 (syms_of_fns): New symbols.
16234 2011-06-20 Deniz Dogan <deniz@dogan.se>
16236 * process.c (Fset_process_buffer): Clarify return value in
16239 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16241 * dispnew.c (add_window_display_history): Use BVAR.
16243 * xdisp.c (debug_method_add): Use BVAR.
16244 (check_window_end, dump_glyph_matrix, dump_glyph)
16245 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16247 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16250 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16251 check till after the cache is created in init_frame_faces.
16253 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16255 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16257 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16259 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16260 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16261 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16263 Improve buffer-overflow checking (Bug#8873).
16264 * fileio.c (Finsert_file_contents):
16265 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16266 Remove the old (too-loose) buffer overflow checks.
16267 They weren't needed, since make_gap checks for buffer overflow.
16268 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16269 The old code merely checked for Emacs fixnum overflow, and relied
16270 on undefined (wraparound) behavior. The new code avoids undefined
16271 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16273 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16274 Tune. Don't use wider integers than needed. Don't use alloca.
16275 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16277 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16279 * insdel.c, lisp.h (buffer_overflow): New function.
16280 (insert_from_buffer_1, replace_range, replace_range_2):
16281 * insdel.c (make_gap_larger):
16282 * editfns.c (Finsert_char):
16283 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16285 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16287 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16289 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16291 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16292 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16294 * fileio.c: Don't assume EMACS_INT fits in off_t.
16295 (emacs_lseek): New static function.
16296 (Finsert_file_contents, Fwrite_region): Use it.
16297 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16299 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16301 * fns.c: Don't overflow int when computing a list length.
16302 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16303 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16304 truncation on 64-bit hosts. Check for QUIT every
16305 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16306 faster and is responsive enough.
16307 (Flength): Report an error instead of overflowing an integer.
16308 (Fsafe_length): Return a float if the value is not representable
16309 as a fixnum. This shouldn't happen except in contrived situations.
16310 (Fnthcdr, Fsort): Don't assume list length fits in int.
16311 (Fcopy_sequence): Don't assume vector length fits in int.
16313 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16314 (header_size, word_size): New constants.
16315 (allocate_vectorlike): Don't check size overflow here.
16316 (allocate_vector): Check it here instead, since this is the only
16317 caller of allocate_vectorlike that could cause overflow.
16318 Check that the new vector's length is representable as a fixnum.
16320 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16321 The previous code was bogus. For example, next_almost_prime (32)
16322 returned 39, which is undesirable as it is a multiple of 3; and
16323 next_almost_prime (24) returned 25, which is a multiple of 5 so
16324 why was the code bothering to check for multiples of 7?
16326 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16328 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16330 Variadic C functions now count arguments with ptrdiff_t.
16331 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16332 Back then I didn't know that the Emacs coding style prefers signed int.
16333 Also, in the meantime I found a few more instances where arguments
16334 were being counted with int, which may truncate counts on 64-bit
16335 machines, or EMACS_INT, which may be unnecessarily wide.
16336 * lisp.h (struct Lisp_Subr.function.aMANY)
16337 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16338 Arg counts are now ptrdiff_t, not size_t.
16339 All variadic functions and their callers changed accordingly.
16340 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16341 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16342 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16343 * callint.c (Fcall_interactively): Check arg count for overflow,
16344 to avoid potential buffer overrun. Use signed char, not 'int',
16345 for 'varies' array, so that we needn't bother to check its size
16346 calculation for overflow.
16347 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16348 * eval.c (apply_lambda):
16349 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16350 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16351 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16353 * callint.c (Fcall_interactively): Don't use index var as event count.
16355 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16356 * mem-limits.h (SIZE): Remove; no longer used.
16358 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16360 Remove unnecessary casts.
16361 * xterm.c (x_term_init):
16362 * xfns.c (x_set_border_pixel):
16363 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16364 These aren't needed now that we assume ANSI C.
16366 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16367 It's more likely to cause problems (due to unsigned overflow)
16370 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16372 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16374 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16376 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16378 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16380 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16382 GLYPH_CODE_FACE returns EMACS_INT, not int.
16383 * dispextern.h (merge_faces):
16384 * xfaces.c (merge_faces):
16385 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16386 Don't assume EMACS_INT fits in int.
16388 * character.h (CHAR_VALID_P): Remove unused parameter.
16389 * fontset.c, lisp.h, xdisp.c: All uses changed.
16391 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16393 * fns.c (concat): Minor tuning based on overflow analysis.
16394 This doesn't fix any bugs. Use int to hold character, instead
16395 of constantly refetching from Emacs object. Use XFASTINT, not
16396 XINT, for value known to be a character. Don't bother comparing
16397 a single byte to 0400, as it's always less.
16399 * floatfns.c (Fexpt):
16400 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16402 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16405 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16407 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16408 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16409 incorrectly succeed when S was a string, because 4294967386 was
16410 truncated before it was used.
16412 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16413 Otherwise, an out-of-range integer could cause undefined behavior
16416 * composite.c: Use int, not EMACS_INT, for characters.
16417 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16418 EMACS_INT, for values that are known to be in character range.
16419 This doesn't fix any bugs but is the usual style inside Emacs and
16420 may generate better code on 32-bit machines.
16422 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16423 This is for reasons similar to the recent CHAR_STRING fix.
16424 * charset.c (Fencode_char): Check that character arg is actually
16425 a character. Pass an int to ENCODE_CHAR.
16426 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16427 wider than 'int', as a compile-time check to prevent future regressions
16430 * character.c (char_string): Remove unnecessary casts.
16432 Make sure a 64-bit char is never passed to CHAR_STRING.
16433 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16434 by silently ignoring the top 32 bits, allowing some values
16435 that were far too large to be valid characters.
16436 * character.h: Include <verify.h>.
16437 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16438 arguments are no wider than unsigned, as a compile-time check
16439 to prevent future regressions in this area.
16441 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16442 (Fsubst_char_in_region):
16444 * xdisp.c (decode_mode_spec_coding):
16445 Adjust to CHAR_STRING's new requirement.
16446 * editfns.c (Finsert_char, Fsubst_char_in_region):
16447 * fns.c (concat): Check that character args are actually
16448 characters. Without this test, these functions did the wrong
16449 thing with wildly out-of-range values on 64-bit hosts.
16451 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16452 These casts should not be needed on 32-bit hosts, either.
16453 * keyboard.c (read_char):
16454 * lread.c (Fload): Remove casts to unsigned.
16456 * lisp.h (UNSIGNED_CMP): New macro.
16457 This fixes comparison bugs on 64-bit hosts.
16458 (ASCII_CHAR_P): Use it.
16459 * casefiddle.c (casify_object):
16460 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16461 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16462 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16463 * dispextern.h (FACE_FROM_ID):
16464 * keyboard.c (read_char): Use UNSIGNED_CMP.
16466 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16467 not to EMACS_INT, to avoid GCC warning.
16469 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16471 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16472 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16473 isn't needed on 32-bit machines.
16475 * buffer.c (Fgenerate_new_buffer_name):
16476 Use EMACS_INT for count, not int.
16477 (advance_to_char_boundary): Return EMACS_INT, not int.
16479 * data.c (Qcompiled_function): Now static.
16481 * window.c (window_body_lines): Now static.
16483 * image.c (gif_load): Rename local to avoid shadowing.
16485 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16486 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16487 * alloc.c (make_save_value): Integer argument is now of type
16488 ptrdiff_t, not int.
16489 (mark_object): Use ptrdiff_t, not int.
16490 * lisp.h (pD): New macro.
16491 * print.c (print_object): Use it.
16493 * alloc.c: Use EMACS_INT, not int, to count objects.
16494 (total_conses, total_markers, total_symbols, total_vector_size)
16495 (total_free_conses, total_free_markers, total_free_symbols)
16496 (total_free_floats, total_floats, total_free_intervals)
16497 (total_intervals, total_strings, total_free_strings):
16498 Now EMACS_INT, not int. All uses changed.
16499 (Fgarbage_collect): Compute overall total using a double, so that
16500 integer overflow is less likely to be a problem. Check for overflow
16501 when converting back to an integer.
16502 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16503 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16504 These were 'int' variables that could overflow on 64-bit hosts;

17035 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
17036 Do not assume that spare memory exists; that assumption is valid
17037 only if SYSTEM_MALLOC.
17038 (LARGE_REQUEST): New macro, so that the issue of large requests
17039 is separated from the issue of spare memory.

17108 instead of using explicit *_CHAR codes.
17109 (bidi_resolve_explicit, bidi_resolve_weak):

17118 (bidi_level_of_next_char): Don't try to lookup the cache for the
17119 next/previous character if nothing is cached there yet, or if we
17120 were just reseat()'ed to a new position.
17122 * xdisp.c (set_cursor_from_row): Set start and stop points
17123 according to the row's direction when priming the loop that looks
17124 for the glyph on which to display cursor.

17126 (display_prop_intangible_p): Reimplement to call
17127 handle_display_spec instead of single_display_spec_intangible_p.
17128 Accept 3 additional arguments needed by handle_display_spec.
17129 This fixes incorrect cursor motion across display property with complex
17130 values: lists, `(when COND...)' forms, etc.

17132 lists with the argument STRING its top-level element.
17133 (display_prop_string_p): Fix the condition for processing a

17136 last portion of handle_display_prop.
17137 (compute_display_string_pos): Accept additional argument
17138 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17139 value of a `display' property is a "replacing spec".
17140 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17141 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17142 the display property, but just return a value indicating whether
17143 the display property will replace the characters it covers.
17144 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17145 frame_window_p members of struct bidi_it.
17146 (compute_display_string_pos, compute_display_string_end):

17152 * keyboard.c (adjust_point_for_property): Adjust the call to
17153 display_prop_intangible_p to its new signature.

17169 All callers changed. (Bug#8762)
17171 * gnutls.c: Use Emacs's memory allocators.
17172 Without this change, the gnutls library would invoke malloc etc.
17173 directly, which causes problems on non-SYNC_INPUT hosts, and which
17174 runs afoul of improving memory_full behavior. (Bug#8761)
17175 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17176 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17177 xfree instead of the default malloc, realloc, free.
17178 (Fgnutls_boot): No need to check for memory allocation failure,
17179 since xmalloc does that for us.
17181 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17182 * category.c (hash_get_category_set):

17201 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17202 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17203 * alloc.c (allocate_vectorlike):
17204 Check for overflow in vector size calculations.
17205 * ccl.c (ccl_driver):
17206 Check for overflow when converting EMACS_INT to int.
17207 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17208 need to be updated by these changes.
17209 * fns.c (make_hash_table, maybe_resize_hash_table):
17210 Check for integer overflow with large hash tables.
17211 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17212 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17213 (SXHASH_REDUCE): New macro.
17214 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17215 Use it instead of discarding useful hash info with large hash values.
17216 (sxhash_float): New function.
17217 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17218 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17219 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17220 Rewrite to use FIXNUM_BITS, as this simplifies things.
17221 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17222 Adjust signatures to match updated version of code.
17223 (consing_since_gc): Now EMACS_INT, since a single hash table can
17224 use more than INT_MAX bytes.

17273 Make it possible to run ./temacs.
17275 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17276 syms_of_callproc does the same thing. Remove test for
17277 "initialized", do it in the caller.
17278 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17280 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>

17337 * fns.c (to_uchar): Define.
17338 (crypto_hash_function): Use it to convert some newly-signed
17339 variables to unsigned, to avoid sign-extension bugs. For example,
17340 without this change, (md5 "truc") would evaluate to
17341 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17342 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

17354 Check for serial numbers out of range. Decode any serial number
17355 that was so large that it became a float. (Bug#8722)
17357 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17358 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17359 Use XFASTINT rather than XUINT when numbers are nonnegative.
17360 (xd_append_arg, Fdbus_method_return_internal):
17361 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17362 arguments, check that Lisp number is nonnegative, rather than
17363 silently wrapping negative numbers around. (Bug#8722)
17364 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17367 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.

17373 (IN_INT_RANGE): New macros.
17374 (ccl_driver): Use them to check for integer overflow when
17375 decoding a CCL program. Many of the new checks are whether XINT (x)
17376 fits in int; it doesn't always, on 64-bit hosts. The new version
17377 doesn't catch all possible integer overflows, but it's an
17378 improvement. (Bug#8719)
17380 * alloc.c (make_event_array): Use XINT, not XUINT.
17381 There's no need for unsigned here.
17383 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17384 This follows up to the 2011-05-06 change that substituted uintptr_t
17385 for EMACS_INT. This case wasn't caught back then.
17387 Rework Fformat to avoid integer overflow issues.
17388 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17389 now (part of C89). Include <verify.h>.
17390 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17391 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17392 (Fformat): Avoid the prepass trying to compute sizes; it was only
17393 approximate and thus did not catch overflow reliably. Instead, walk
17394 through the format just once, formatting and computing sizes as we go,
17395 checking for integer overflow at every step, and allocating a larger
17396 buffer as needed. Keep track separately whether the format is
17397 multibyte. Keep only the most-recently calculated precision, rather
17398 than them all. Record whether each argument has been converted to
17399 string. Use EMACS_INT, not int, for byte and char and arg counts.
17400 Support field widths and precisions larger than INT_MAX. Avoid
17401 sprintf's undefined behavior with conversion specifications such as %#d
17402 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17403 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17404 formatting out-of-range floating point numbers with int
17405 formats. (Bug#8668)
17407 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17409 * data.c: Avoid integer truncation in expressions involving floats.
17410 * data.c: Include <intprops.h>.
17411 (arith_driver): When there's an integer overflow in an expression
17412 involving floating point, convert the integers to floating point
17413 so that the resulting value does not suffer from catastrophic
17414 integer truncation. For example, on a 64-bit host (* 4
17415 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17416 Do not rely on undefined behavior after integer overflow.
17418 merge count_size_as_multibyte, parse_str_to_multibyte
17419 * character.c, character.h (count_size_as_multibyte):
17420 Rename from parse_str_to_multibyte; all uses changed.
17421 Check for integer overflow.
17422 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17423 since it's now a duplicate of the other. This is more of
17424 a character than a buffer op, so better that it's in character.c.
17425 * fns.c, print.c: Adjust to above changes.
17427 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17429 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17431 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17433 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17434 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17435 (x_clipboard_manager_save): Now static.
17436 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17438 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17439 (crypto_hash_function): Now static.
17440 Fix pointer signedness problems. Avoid unnecessary initializations.
17442 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17444 * termhooks.h (Vselection_alist): Make it terminal-local.
17446 * terminal.c (create_terminal): Initialize it.
17448 * xselect.c: Support for clipboard managers.
17449 (Vselection_alist): Move to termhooks.h as terminal-local var.
17450 (LOCAL_SELECTION): New macro.
17451 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17452 (symbol_to_x_atom): Remove gratuitous arg.
17453 (x_handle_selection_request, lisp_data_to_selection_data)
17454 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17455 (x_own_selection, x_get_local_selection, x_convert_selection):
17456 New arg, specifying work frame. Use terminal-local Vselection_alist.
17457 (some_frame_on_display): Delete unused function.
17458 (Fx_own_selection_internal, Fx_get_selection_internal)
17459 (Fx_disown_selection_internal, Fx_selection_owner_p)
17460 (Fx_selection_exists_p): New optional frame arg.
17461 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17462 (x_handle_selection_clear): Don't treat other terminals with the
17463 same keyboard specially. Use the terminal-local Vselection_alist.
17464 (x_clear_frame_selections): Use Frun_hook_with_args.
17466 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17468 * xterm.h: Add support for those atoms.
17470 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17472 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17473 (converted_selections, conversion_fail_tag): New global variables.
17474 (x_selection_request_lisp_error): Free the above.
17475 (x_get_local_selection): Remove unnecessary code.
17476 (x_reply_selection_request): Args changed; handle arbitrary array
17477 of converted selections stored in converted_selections.
17478 Separate the XChangeProperty and SelectionNotify steps.
17479 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17480 (x_convert_selection): New function.
17481 (x_handle_selection_event): Simplify.
17482 (x_get_foreign_selection): Don't ignore incoming requests while
17483 waiting for an answer; this will fail when we implement
17484 SAVE_TARGETS, and seems unnecessary anyway.
17485 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17486 (Vx_sent_selection_functions): Doc fix.
17488 2011-05-26 Leo Liu <sdl.web@gmail.com>
17490 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17492 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17494 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17496 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17497 for fringe update if it has periodic bitmap.
17498 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17499 and fringe_bitmap_periodic_p.
17501 * fringe.c (get_fringe_bitmap_data): New function.
17502 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17503 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17504 row. Mark glyph row for fringe update if periodicity changed.
17506 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17507 for fringe update unless it has periodic bitmap.
17509 2011-05-25 Kenichi Handa <handa@m17n.org>
17511 * xdisp.c (get_next_display_element): Set correct it->face_id for
17512 a static composition.
17514 2011-05-24 Leo Liu <sdl.web@gmail.com>
17517 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17519 * fns.c (crypto_hash_function, Fsha1): New function.
17520 (Fmd5): Use crypto_hash_function.
17521 (syms_of_fns): Add Ssha1.
17523 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17525 * gnutls.c: Remove unused macros.
17526 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17527 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17528 Remove macros that are defined and never used.
17529 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17531 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17533 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17534 (Fx_get_selection_internal): Minor cleanup.
17535 (Fx_own_selection_internal): Rename arguments for consistency with
17538 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17540 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17542 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17544 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17546 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17548 * dispnew.c (scrolling_window): Don't exclude the case that the
17549 last enabled row in the desired matrix touches the bottom boundary.
17551 2011-05-21 Glenn Morris <rgm@gnu.org>
17553 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17554 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17555 and add some more files.
17557 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17559 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17560 report_file_error introduced by the change from 2011-05-07.
17562 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17564 * systime.h (Time): Define only if emacs is defined.
17565 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17566 where the include path doesn't have X11/X.h by default. See
17567 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17569 2011-05-20 Kenichi Handa <handa@m17n.org>
17571 * composite.c (find_automatic_composition): Fix previous change.
17573 2011-05-20 Glenn Morris <rgm@gnu.org>
17575 * lisp.mk: New file, split from Makefile.in.
17576 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17577 (shortlisp): Remove.
17578 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17580 2011-05-19 Glenn Morris <rgm@gnu.org>
17582 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17583 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17584 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17585 (lisp): Set the order to that of loadup.el.
17586 (shortlisp): Make it a copy of $lisp.
17587 (SOME_MACHINE_LISP): Remove.
17588 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17589 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17591 2011-05-18 Kenichi Handa <handa@m17n.org>
17593 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17594 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17595 (find_automatic_composition): Mostly rewrite for efficiency.
17597 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17599 * makefile.w32-in: Update dependencies.
17601 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17603 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17604 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17606 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17608 Fix some integer overflow issues, such as string length overflow.
17610 * insdel.c (count_size_as_multibyte): Check for string overflow.
17612 * character.c (lisp_string_width): Check for string overflow.
17613 Use EMACS_INT, not int, for string indexes and lengths; in
17614 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17615 the resulting string length overflows an EMACS_INT; instead,
17616 report a string overflow if no precision given. When checking for
17617 precision exhaustion, use a check that cannot possibly have
17618 integer overflow. (Bug#8675)
17619 * character.h (lisp_string_width): Adjust to new signature.
17621 * alloc.c (string_overflow): New function.
17622 (Fmake_string): Use it. This doesn't change behavior, but saves
17623 a few bytes and will simplify future changes.
17624 * character.c (string_escape_byte8): Likewise.
17625 * lisp.h (string_overflow): New decl.
17627 Fixups, following up to the user-interface timestamp change.
17628 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17629 for UI timestamps, instead of unsigned long.
17630 * msdos.c (mouse_get_pos): Likewise.
17631 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17632 * w32gui.h (Time): Define by including "systime.h" rather than by
17633 declaring it ourselves. (Bug#8664)
17635 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17636 * image.c (clear_image_cache): Likewise.
17638 * term.c (term_mouse_position): Don't assume time_t wraparound.
17640 Be more systematic about user-interface timestamps.
17641 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17642 and sometimes 'EMACS_UINT', to represent these timestamps.
17643 This change causes it to use 'Time' uniformly, as that's what X uses.
17644 This makes the code easier to follow, and makes it easier to catch
17645 integer overflow bugs such as Bug#8664.
17646 * frame.c (Fmouse_position, Fmouse_pixel_position):
17647 Use Time, not unsigned long, for user-interface timestamps.
17648 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17649 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17650 * keyboard.h (last_event_timestamp): Likewise.
17651 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17652 * menu.h (xmenu_show): Likewise.
17653 * term.c (term_mouse_position): Likewise.
17654 * termhooks.h (struct input_event.timestamp): Likewise.
17655 (struct terminal.mouse_position_hook): Likewise.
17656 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17657 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17658 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17659 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17660 what it was before.
17661 * menu.h, termhooks.h: Include "systime.h", for Time.
17663 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17664 Don't assume that the difference between two unsigned long values
17665 can fit into an integer. At this point, we know button_down_time
17666 <= event->timestamp, so the difference must be nonnegative, so
17667 there's no need to cast the result if double-click-time is
17668 nonnegative, as it should be; check that it's nonnegative, just in
17669 case. This bug is triggered when events are more than 2**31 ms
17670 apart (about 25 days). (Bug#8664)
17672 * xselect.c (last_event_timestamp): Remove duplicate decl.
17673 (x_own_selection): Remove needless cast to unsigned long.
17675 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17676 that always fit in int. Use a sentinel instead of a counter, to
17677 avoid a temp and to allay GCC's concerns about possible int overflow.
17678 * frame.h (struct frame): Use int for menu_bar_items_used
17679 instead of EMACS_INT, since it always fits in int.
17681 * menu.c (grow_menu_items): Check for int overflow.
17683 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17685 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17686 Before, the code was not consistent. These values cannot exceed
17687 2**31 - 1 so there's no need to make them unsigned.
17688 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17689 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17690 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17692 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17694 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17695 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17696 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17697 presumably because the widths might not match.
17699 * window.c (size_window): Avoid needless test at loop start.
17701 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17703 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17705 2011-05-12 Drew Adams <drew.adams@oracle.com>
17707 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17709 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17711 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17712 `width' to `bar_area_x' and `bar_area_width', respectively.
17713 (x_scroll_run): Take account of fringe background extension.
17715 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17716 Rename local vars `left' and `width' to `bar_area_x' and
17717 `bar_area_width', respectively.
17718 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17719 background extension.
17721 2011-05-10 Jim Meyering <meyering@redhat.com>
17723 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17725 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17727 * image.c (Finit_image_library): Return t for built-in image types,
17728 like pbm and xbm. (Bug#8640)
17730 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17732 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17734 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17736 * w32console.c (Fset_screen_color): Doc fix.
17737 (Fget_screen_color): New function.
17738 (syms_of_ntterm): Defsubr it.
17740 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17741 unlink the temporary file if Fcall_process didn't create it in the
17743 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17744 child process will be redirected to a file specified with `:file'.
17745 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17746 cue to call_process_cleanup not to close that handle.
17748 2011-05-07 Ben Key <bkey76@gmail.com>
17750 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17751 one of two shell specific rules, either bootstrap-temacs-CMD or
17752 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17753 to the previous implementation of the bootstrap-temacs rule.
17754 The bootstrap-temacs-CMD rule is similar to the previous
17755 implementation of the bootstrap-temacs rule except that it
17756 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17759 These changes, along with some changes to nt/configure.bat,
17760 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17761 earlier fix to add support for --cflags and --ldflags options
17762 that include quotes so that it works whether make uses cmd or
17765 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17767 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17768 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17770 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17771 a string. Handle both cases.
17772 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17773 (Fdbus_register_method): Use Qinvalid_function.
17775 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17777 * makefile.w32-in: Update dependencies.
17778 (LISP_H): Add inttypes.h and stdin.h.
17779 (PROCESS_H): Add unistd.h.
17781 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17783 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17784 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17786 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17788 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17790 * term.c (vfatal): Remove stray call to va_end.
17791 It's not needed and the C Standard doesn't allow it here anyway.
17793 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17794 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17796 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17799 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17801 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17803 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17805 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17807 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17809 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17810 * charset.c (Fdefine_charset_internal): Don't initialize
17811 charset.code_space[15]. The value was garbage, on hosts with
17812 32-bit int (Bug#8600).
17814 * lread.c (read_integer): Be more consistent with string-to-number.
17815 Use string_to_number to do the actual conversion; this avoids
17816 rounding errors and fixes some other screwups. Without this fix,
17817 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17818 (digit_to_number): Move earlier, for benefit of read_integer.
17819 Return -1 if the digit is out of range for the base, -2 if it is
17820 not a digit in any supported base. (Bug#8602)
17822 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17824 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17825 to match comment at start of function. This also removes a
17826 GCC warning about overflow in a 32+64-bit port.
17828 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17830 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17831 Reported by Stefan Monnier in
17832 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17833 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17834 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17836 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17837 (EMACS_UINTPTR): Likewise, with uintptr_t.
17839 * lisp.h: Prefer 64-bit EMACS_INT if available.
17840 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17841 on 32-bit hosts that have 64-bit int, so that they can access
17843 However, temporarily disable this change unless the temporary
17844 symbol WIDE_EMACS_INT is defined.
17846 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17848 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17849 This removes an assumption that EMACS_INT and long are the same
17850 width as pointers. The assumption is true for Emacs porting targets
17851 now, but we want to make other targets possible.
17852 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17853 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17854 In the rest of the code, change types of integers that hold casted
17855 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17856 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17857 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17858 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17859 No need to cast type when ORing.
17860 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17861 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17862 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17863 assume EMACS_INT is the same width as char *.
17864 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17865 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17866 Remove no-longer-needed casts.
17867 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17868 (xg_tool_bar_help_callback, xg_make_tool_item):
17869 Use EMACS_INTPTR to hold an integer
17870 that will be cast to void *; this can avoid a GCC warning
17871 if EMACS_INT is not the same width as void *.
17872 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17873 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17874 (current_message_1, set_message_1):
17875 Use a local to convert to proper width without a cast.
17876 * xmenu.c (dialog_selection_callback): Likewise.
17878 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17879 Also, don't assume VALBITS / RAND_BITS is less than 5,
17880 and don't rely on undefined behavior when shifting a 1 left into
17882 * lisp.h (get_random): Change signature to match.
17884 * lread.c (hash_string): Use size_t, not int, for hash computation.
17885 Normally we prefer signed values; but hashing is special, because
17886 it's better to use unsigned division on hash table sizes so that
17887 the remainder is nonnegative. Also, size_t is the natural width
17888 for hashing into memory. The previous code used 'int', which doesn't
17889 retain enough info to hash well into very large tables.
17890 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17892 * dbusbind.c: Don't possibly lose pointer info when converting.
17893 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17894 Use XPNTR rather than XHASH, so that the high-order bits of
17895 the pointer aren't lost when converting through void *.
17897 * eval.c (Fautoload): Don't double-shift a pointer.
17899 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17901 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17903 * gnutls.c (DEF_GNUTLS_FN):
17904 * image.c (DEF_IMGLIB_FN): Make function pointers static.

17922 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17923 `gnutls_certificate_set_x509_key_file'.
17925 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

17932 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17933 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17934 Remove unused parameter `fildes'.
17935 * process.c (read_process_output, send_process): Don't pass it.
17937 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17939 Fix previous change: the library cache is defined in w32.c.
17940 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17941 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17943 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17945 Implement dynamic loading of GnuTLS on Windows.
17947 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17948 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17949 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17952 * gnutls.c (Qgnutls_dll): Define.
17953 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17954 (gnutls_*): Declare function pointers.

17958 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17959 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17960 (emacs_gnutls_write, emacs_gnutls_read)
17961 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17962 (Fgnutls_available_p): New function.
17963 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

17973 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17975 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17976 (w32_delayed_load): Move from image.c. When loading a library, record
17977 its filename in the :loaded-from property of the library id.
17978 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17979 Initialize and staticpro them.
17980 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17982 * process.c: Include lisp.h before w32.h, not after.
17983 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17984 instead of gnutls_record_check_pending.
17986 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17988 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17990 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17991 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17994 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17996 * xterm.c (x_set_frame_alpha): Do not set property on anything
17997 else than FRAME_X_OUTER_WINDOW (Bug#8608).
17999 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18001 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18003 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18005 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

18020 (wait_for_termination, interruptible_wait_for_termination):
18021 Move after wait_for_termination_1.
18023 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18025 * sysdep.c (interruptible_wait_for_termination): New function
18026 which is like wait_for_termination, but allows keyboard
18029 * callproc.c (Fcall_process): Add (:file "file") as an option for
18031 (Fcall_process_region): Ditto.
18033 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18035 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18036 rather than `XVECTOR (FOO)->size'.
18038 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18039 inttypes.h, as a gnulib replacement is used if it not available in
18042 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18044 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18045 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18046 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18048 * coding.c (coding_alloc_by_realloc): Error out if destination
18049 will grow beyond MOST_POSITIVE_FIXNUM.
18050 (decode_coding_emacs_mule): Abort if there isn't enough place in
18051 charbuf for the composition carryover bytes. Reserve an extra
18052 space for up to 2 characters produced in a loop.
18053 (decode_coding_iso_2022): Abort if there isn't enough place in
18054 charbuf for the composition carryover bytes.
18056 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18058 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18059 aborting when %lld or %lll format is passed.
18060 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18061 %llo or %llx format is passed. (Bug#8545)
18063 * window.c (window_scroll_line_based): Use a marker instead of
18064 simple variables to record original value of point. (Bug#7952)
18066 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18067 produced by %s or %c overflows available buffer space. (Bug#8545)
18069 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18071 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

18080 * keyboard.c (Qdelayed_warnings_hook): Define.
18081 (command_loop_1): Run `delayed-warnings-hook'
18082 if Vdelayed_warnings_list is non-nil.
18083 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18084 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18086 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18088 * doprnt.c (doprnt): Don't return value smaller than the buffer
18089 size if the message was truncated. (Bug#8545).
18091 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18093 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18094 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18096 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18098 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18100 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18102 * makefile.w32-in: Update dependencies.
18104 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18106 Improve `doprnt' and its usage. (Bug#8545)
18107 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18108 `format_end'. Remove support for %l as a conversion specifier.
18109 Don't use xrealloc. Improve diagnostics when the %l size modifier
18110 is used. Update the commentary.
18112 * eval.c (verror): Simplify calculation of size_t.
18114 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18117 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18119 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18122 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18124 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18125 This makes this file independent of the recent pseudovector change.
18127 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18129 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18131 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18132 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18133 Remove unused local.
18134 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18136 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18137 GCC 4.6.0 optimizes based on type-based alias analysis.
18138 For example, if b is of type struct buffer * and v of type struct
18139 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18140 != &v->size, and therefore "v->size = 1; b->size = 2; return
18141 v->size;" must therefore return 1. This assumption is incorrect
18142 for Emacs, since it type-puns struct Lisp_Vector * with many other
18143 types. To fix this problem, this patch adds a new type struct
18144 vectorlike_header that documents the constraints on layout of vectors
18145 and pseudovectors, and helps optimizing compilers not get fooled
18146 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18147 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18148 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18150 (XSETPVECTYPE): Rewrite in terms of new macro.
18151 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18152 This is a bit clearer, and further avoids the possibility of
18153 undesirable aliasing.
18154 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18155 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18156 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18157 since Lisp_Subr is a special case (no "next" field).
18158 (ASIZE): Now uses header.size rather than size.
18159 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18160 to avoid the hassle of writing XVECTOR (foo)->header.size.
18161 (struct vectorlike_header): New type.
18162 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18163 object, to help avoid aliasing.
18164 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18165 (SUBRP): Likewise, since Lisp_Subr is a special case.
18166 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18167 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18168 (struct Lisp_Hash_Table): Combine first two members into a single
18169 struct vectorlike_header member. All uses of "size" and "next" members
18170 changed to be "header.size" and "header.next".
18171 * buffer.h (struct buffer): Likewise.
18172 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18173 * frame.h (struct frame): Likewise.
18174 * process.h (struct Lisp_Process): Likewise.
18175 * termhooks.h (struct terminal): Likewise.
18176 * window.c (struct save_window_data, struct saved_window): Likewise.
18177 * window.h (struct window): Likewise.
18178 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18179 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18180 * buffer.c (init_buffer_once): Likewise.
18181 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18183 * process.c (Fformat_network_address): Use local var for size,
18186 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18188 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18189 * data.c (atof): Remove decl; no longer used or needed.
18190 (digit_to_number): Move to lread.c.
18191 (Fstring_to_number): Use new string_to_number function, to be
18192 consistent with how the Lisp reader treats infinities and NaNs.
18193 Do not assume that floating-point numbers represent EMACS_INT
18194 without losing information; this is not true on most 64-bit hosts.
18195 Avoid double-rounding errors, by insisting on integers when
18196 parsing non-base-10 numbers, as the documentation specifies.
18197 * lisp.h (string_to_number): New decl, replacing ...
18198 (isfloat_string): Remove.
18199 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18200 (read1): Do not accept +. and -. as integers; this
18201 appears to have been a coding error. Similarly, do not accept
18202 strings like +-1e0 as floating point numbers. Do not report
18203 overflow for integer overflows unless the base is not 10 which
18204 means we have no simple and reliable way to continue.
18205 Break out the floating-point parsing into a new
18206 function string_to_number, so that Fstring_to_number parses
18207 floating point numbers consistently with the Lisp reader.
18208 (digit_to_number): Move here from data.c. Make it static inline.
18209 (E_CHAR, EXP_INT): Remove, replacing with ...
18210 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18211 (string_to_number): New function, replacing isfloat_string.
18212 This function checks for valid syntax and produces the resulting
18213 Lisp float number too. Rework it so that string-to-number
18214 no longer mishandles examples like "1.0e+". Use strtoumax,
18215 so that overflow for non-base-10 numbers is reported only when
18216 there's no portable and simple way to convert to floating point.
18218 * textprop.c (set_text_properties_1): Rewrite for clarity,
18219 and to avoid GCC warning about integer overflow.
18221 * intervals.h (struct interval): Use EMACS_INT for members
18222 where EMACS_UINT might cause problems. See
18223 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18224 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18225 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18227 (offset_intervals): Tell GCC not to worry about length overflow
18228 when negating a negative length.
18230 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18231 (overrun_check_free): Likewise.

18243 * lread.c (openp): Don't stuff size_t into an 'int'.
18244 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18245 about possible signed overflow.
18247 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18248 (GDK_KEY_g): Don't define if already defined.

18250 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18252 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18253 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18255 * xfns.c (Fx_window_property): Simplify a bit,
18256 to make a bit faster and to avoid GCC 4.6.0 warning.
18257 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18259 * fns.c (internal_equal): Don't assume size_t fits in int.
18261 * alloc.c (compact_small_strings): Tighten assertion a little.
18263 Replace pEd with more-general pI, and fix some printf arg casts.
18264 * lisp.h (pI): New macro, generalizing old pEd macro to other
18265 conversion specifiers. For example, use "...%"pI"d..." rather
18266 than "...%"pEd"...".
18267 (pEd): Remove. All uses replaced with similar uses of pI.
18268 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18269 * alloc.c (check_pure_size): Don't overflow by converting size to int.

18273 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18274 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18276 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18277 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18278 * print.c (safe_debug_print, print_object): Likewise.
18279 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18281 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18282 avoiding the 0 flag, which is not portable.

18284 * region-cache.c (pp_cache): Likewise.
18285 * xdisp.c (decode_mode_spec): Likewise.

18287 behavior on 64-bit hosts with printf arg.
18288 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18289 (x_stop_queuing_selection_requests): Likewise.
18290 (x_get_window_property): Don't truncate byte count to an 'int'
18293 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18294 here, since it parses constructs like leading '-' and spaces,
18295 which are not wanted; and it overflows with large numbers.
18296 Instead, simply match F[0-9]+, which is what is wanted anyway.
18298 * alloc.c: Remove unportable assumptions about struct layout.
18299 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18300 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18301 (allocate_vectorlike, make_pure_vector): Use the new macros,
18302 plus offsetof, to remove unportable assumptions about struct layout.
18303 These assumptions hold on all porting targets that I know of, but
18304 they are not guaranteed, they're easy to remove, and removing them
18305 makes further changes easier.
18307 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18308 This doesn't fix a bug but makes the code clearer.
18309 (string_overrun_cookie): Now const. Use initializers that
18310 don't formally overflow signed char, to avoid warnings.
18311 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18312 can cause Emacs to crash when string overrun checking is enabled.
18313 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18314 multiple of sizeof (EMACS_INT); it need not be, if
18315 alignof(EMACS_INT) < sizeof (EMACS_INT).
18316 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18318 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18347 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18348 "cast to pointer from integer of different size".
18350 Improve doprnt and its use in verror. (Bug#8545)
18351 * doprnt.c (doprnt): Document the set of format control sequences
18352 supported by the function. Use SAFE_ALLOCA instead of always
18355 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18356 is one byte too soon. Don't use xrealloc; instead xfree and
18359 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18361 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

18367 parameters of `gnutls-boot' and documented those parameters in the
18368 docstring. Start callback support.
18369 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18370 unless a fatal error occurred. Call gnutls_alert_send_appropriate

18474 codepoint of an invalid character, to avoid displaying a bogus
18477 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18478 `error', not SYMBOL_NAME itself.
18480 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

18483 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18484 to `error' in error message about FINAL_CHAR argument. Make sure
18485 FINAL_CHAR is a character, and use %c when it is passed as
18486 argument to `error'.
18488 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18490 * s/ms-w32.h (localtime): Redirect to sys_localtime.
18492 * w32.c: Include <time.h>.

18552 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18553 by pacifying GCC about it. Maybe it's time to retire it?
18554 * xfaces.c (USG, __TIMEVAL__): Likewise.
18556 * dispextern.h (struct redisplay_interface): Rename param
18557 to avoid shadowing.
18558 * termhooks.h (struct terminal): Likewise.
18559 * xterm.c (xembed_send_message): Likewise.

18660 (group_in_compile_stack, re_search, re_search_2, regex_compile)
18661 (re_compile_pattern, re_exec): Declare arguments and local
18662 variables `size_t' and `ssize_t' and return values `regoff_t', as

18675 * nsfont.m: Fixed bugs in ns_get_family and
18676 ns_descriptor_to_entity that were caused by using free to
18677 deallocate memory blocks that were allocated by xmalloc (via
18678 xstrdup). This caused Emacs to crash when compiled with
18679 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18680 --enable-checking=xmallocoverrun). xfree is now used to
18681 deallocate these memory blocks.

18685 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

18695 (emacs_read, emacs_write): Remove check for negative size, as the
18696 Emacs source code has been audited now.
18697 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
18698 (emacs_read, emacs_write): Use it.
18699 * process.c (send_process): Adjust to the new signatures of
18700 emacs_write and emacs_gnutls_write. Do not attempt to store

19113 * buffer.h (Fdelete_overlay): Remove decl.
19114 * callproc.c (Fgetenv_internal): Mark as internal.

19119 * doc.c (Fdocumntation_property): New forward static decl.
19120 * eval.c (Ffetch_bytecode): New forward static decl.
19121 (Funintern): Remove extern decl; now in .h file where it belongs.
19122 * fileio.c (Fmake_symbolic_link): New forward static decl.
19123 * image.c (Finit_image_library): New forward static decl.
19124 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19125 * intervals.h (Fprevious_property_change):
19126 (Fremove_list_of_text_properties): Remove decls.

19149 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19151 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19152 when at ZV. (Bug#8487)
19154 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19156 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19158 * keyboard.c (parse_tool_bar_item): Likewise.
19159 * sound.c (sound_cleanup, alsa_close): Likewise.
19160 * termcap.c (tgetent): Likewise.
19161 * xfns.c (x_default_font_parameter): Likewise.
19162 * xsettings.c (read_and_apply_settings): Likewise.
19164 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19165 (overrun_check_free): Protoize.
19167 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19169 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19170 since callers should never pass a negative size.
19171 Change the signature to match that of plain 'read' and 'write'; see
19172 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19173 * lisp.h: Update prototypes of emacs_write and emacs_read.
19175 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19177 * xdisp.c (redisplay_window): Don't try to determine the character
19178 position of the scroll margin if the window start point w->startp
19179 is outside the buffer's accessible region. (Bug#8468)
19181 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19183 Fix write-region and its subroutines for buffers > 2GB.
19184 * fileio.c (a_write, e_write): Modify declaration of arguments and
19185 local variables to support buffers larger than 2GB.
19186 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19188 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19189 argument, local variables, and return value.
19191 * lisp.h: Update prototypes of emacs_write and emacs_read.
19193 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19195 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19197 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19199 Fix more problems found by GCC 4.6.0's static checks.
19201 * xdisp.c (vmessage): Use a better test for character truncation.
19203 * charset.c (load_charset_map): <, not <=, for optimization,
19204 and to avoid potential problems with integer overflow.
19205 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19206 * casetab.c (set_identity, shuffle): Likewise.
19207 * editfns.c (Fformat): Likewise.
19208 * syntax.c (skip_chars): Likewise.
19210 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19211 This also lets GCC 4.6.0 generate slightly better loop code.
19213 * callint.c (Fcall_interactively): <, not <=, for optimization.
19214 (Fcall_interactively): Count the number of arguments produced,
19215 not the number of arguments given. This is simpler and lets GCC
19216 4.6.0 generate slightly better code.
19218 * ftfont.c: Distingish more carefully between FcChar8 and char.
19219 The previous code passed unsigned char * to a functions like
19220 strlen and xstrcasecmp that expect char *, which does not
19221 conform to the C standard.
19222 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19223 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19224 char * when the C standard requires it.
19226 * keyboard.c (read_char): Remove unused var.
19228 * eval.c: Port to Windows vsnprintf (Bug#8435).
19229 Include <limits.h>.
19230 (SIZE_MAX): Define if the headers do not.
19231 (verror): Do not give up if vsnprintf returns a negative count.
19232 Instead, grow the buffer. This ports to Windows vsnprintf, which
19233 does not conform to C99. Problem reported by Eli Zaretskii.
19234 Also, simplify the allocation scheme, by avoiding the need for
19235 calling realloc, and removing the ALLOCATED variable.
19237 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19239 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19240 But keep the doprint source code for now, as we might revamp it
19241 and use it again (Bug#8435).
19242 * lisp.h (doprnt): Remove.
19243 * Makefile.in (base_obj): Remove doprnt.o.
19244 * deps.mk (doprnt.o): Remove.
19246 error: Print 32- and 64-bit integers portably (Bug#8435).
19247 Without this change, on typical 64-bit hosts error ("...%d...", N)
19248 was used to print both 32- and 64-bit integers N, which relied on
19249 undefined behavior.
19250 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19251 * lisp.h (error, verror): Mark as printf-like functions.
19252 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19253 Report overflow in size calculations when allocating printf buffer.
19254 Do not truncate output string at its first null byte.
19255 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19256 Truncate the output at a character boundary, since vsnprintf does not
19258 * charset.c (check_iso_charset_parameter): Convert internal
19259 character to string before calling 'error', since %c now has the
19261 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19262 overflow when computing char to be passed to 'error'. Do not
19263 pass Lisp_Object to 'error'; pass the integer instead.
19264 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19265 formatted with plain %d.
19267 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19269 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19271 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19273 * xterm.c (x_catch_errors): Remove duplicate declaration.
19275 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19277 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19279 2011-04-10 Jim Meyering <meyering@redhat.com>
19281 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19282 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19283 return ssize_t not "int", and use size_t as the buffer length.
19284 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19285 * gnutls.h: Update declarations.
19286 * process.c (read_process_output): Use ssize_t, to match.
19287 (send_process): Likewise.
19289 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19291 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19293 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19295 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19296 Use unsigned char, to match FcChar8 type definition.
19298 * xterm.c (handle_one_xevent):
19299 * xmenu.c (create_and_show_popup_menu):
19300 * xselect.c (x_decline_selection_request)
19301 (x_reply_selection_request): Avoid type-punned deref of X events.
19303 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19305 Fix some uses of `int' instead of EMACS_INT.
19306 * search.c (string_match_1, fast_string_match)
19307 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19308 (scan_buffer, find_next_newline_no_quit)
19309 (find_before_next_newline, search_command, Freplace_match)
19310 (Fmatch_data): Make some `int' variables be EMACS_INT.
19312 * xdisp.c (display_count_lines): 3rd argument and return value now
19313 EMACS_INT. All callers changed.
19314 (pint2hrstr): Last argument is now EMACS_INT.
19316 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19317 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19318 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
19319 (decode_coding_utf_16, decode_coding_emacs_mule)

19321 (decode_coding_ccl, decode_coding_charset)
19322 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19323 (decode_coding_iso_2022, decode_coding_emacs_mule)
19324 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19325 <char_offset, last_offset>: Declare EMACS_INT.

19327 (encode_coding_emacs_mule, encode_invocation_designation)
19328 (encode_designation_at_bol, encode_coding_iso_2022)
19329 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19330 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19332 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19333 (encode_invocation_designation): Last argument P_NCHARS is now
19335 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19336 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19338 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19341 * ccl.c (Fccl_execute_on_string): Declare some variables
19344 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19346 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19348 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19350 * process.c (Fformat_network_address): Doc fix.
19352 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19354 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19356 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19358 * keyboard.c (read_char): Call Lisp function help-form-show,
19359 instead of using internal_with_output_to_temp_buffer.
19360 (Qhelp_form_show): New var.
19361 (syms_of_keyboard): Use DEFSYM macro.
19363 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19365 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19367 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19369 * process.c (Flist_processes): Remove to Lisp.
19370 (list_processes_1): Delete.
19372 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19374 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19376 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19378 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19380 Fix more problems found by GCC 4.6.0's static checks.

19384 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19386 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19388 * xdisp.c (vmessage): Mark as a printf-like function.
19390 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19392 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19394 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19395 printf-like functions.
19396 (tiff_load): Add casts to remove these marks before passing them
19397 to system-supplied API.
19399 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19401 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19402 This avoids several warnings with gcc -Wstrict-overflow.
19403 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19404 directly, rather than having caller test rule sign. This avoids
19405 some unnecessary tests.
19406 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19407 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19408 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19410 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19411 (xfont_open): Avoid unnecessary tests.
19413 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19415 * composite.h, composite.c (composition_gstring_put_cache):
19416 Use EMACS_INT, not int, for length.

19419 breaking out part of COMPOSITION_DECODE_RULE.
19420 (COMPOSITION_DECODE_RULE): Use it.

19422 by using the new macro.
19424 * textprop.c (set_text_properties_1): Change while to do-while,
19425 since the condition is always true at first.
19427 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19428 (interval_deletion_adjustment): Return unsigned value.
19431 * process.c (list_processes_1, create_pty, read_process_output):

19441 (update_syntax_table): Use unsigned instead of int.
19443 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19444 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19445 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19447 * print.c (print_error_message): Avoid int overflow.
19449 * font.c (font_list_entities): Redo for clarity,
19450 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19452 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19453 (font_score): Avoid potential overflow in diff calculation.
19455 * fns.c (substring_both): Remove var that is set but not used.
19456 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19458 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19460 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19461 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19462 can always succeed if overflow has undefined behavior.
19464 * search.c (boyer_moore, wordify): Remove vars set but not used.
19465 (wordify): Omit three unnecessary tests.
19467 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19468 All callers changed. This avoids the need for an unused var.
19470 * casefiddle.c (casify_region): Remove var that is set but not used.
19472 * dired.c (file_name_completion): Remove var that is set but not used.
19474 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19476 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19477 (Finsert_file_contents): Remove unnecessary code checking fd.
19479 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19480 Check for integer overflow on size calculations.
19482 * buffer.c (Fprevious_overlay_change): Remove var that is set
19485 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19486 Remove vars that are set but not used.
19487 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19488 (timer_check_2): Mark vars as initialized.
19490 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19492 * image.c (lookup_image): Remove var that is set but not used.
19493 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19495 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19496 that are set but not used.
19498 * xfns.c (make_invisible_cursor): Don't return garbage
19499 if XCreateBitmapFromData fails (Bug#8410).
19501 * xselect.c (x_get_local_selection, x_handle_property_notify):
19502 Remove vars that are set but not used.
19504 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19505 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

19510 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19511 Check for overflow.
19513 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19514 (map_tty_color) [!defined MSDOS]: Likewise.
19516 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19518 * coding.c: Remove vars that are set but not used.
19519 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19520 All callers changed.
19521 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19522 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19523 (decode_coding_charset): Remove vars that are set but not used.
19525 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19526 that is set but not used.
19528 * print.c (print_object): Remove var that is set but not used.
19530 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19531 The gnulib version avoids calling malloc in the usual case,
19532 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19533 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19534 * filelock.c (current_lock_owner): Likewise.
19535 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19536 * sysdep.c: Include allocator.h, careadlinkat.h.
19537 (emacs_no_realloc_allocator): New static constant.
19538 (emacs_readlink): New function.
19539 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19540 ../lib/careadlinkat.h.
19542 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19544 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19545 first non-nil return value).
19547 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19549 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19550 if not defined (Bug#8403).
19552 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19554 * xdisp.c (display_count_lines): Remove parameter `start',
19555 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19556 (get_char_face_and_encoding): Remove parameter `multibyte_p',

19561 (get_per_char_metric): Remove parameter `f', unused since
19562 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19564 2011-04-02 Jim Meyering <meyering@redhat.com>
19566 do not dereference NULL upon failed strdup
19567 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19568 (ns_get_family): Likewise.
19570 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19572 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19574 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19576 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19579 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19581 Add lexical binding.
19583 * window.c (Ftemp_output_buffer_show): New fun.
19584 (Fsave_window_excursion):
19585 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19587 * lread.c (lisp_file_lexically_bound_p): New function.
19588 (Fload): Bind Qlexical_binding.
19589 (readevalloop): Remove `evalfun' arg.
19590 Bind Qinternal_interpreter_environment.
19591 (Feval_buffer): Bind Qlexical_binding.
19592 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19594 (syms_of_lread): Declare `lexical-binding'.
19596 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19598 * keyboard.c (eval_dyn): New fun.
19599 (menu_item_eval_property): Use it.
19601 * image.c (parse_image_spec): Use Ffunctionp.
19603 * fns.c (concat, mapcar1): Accept byte-code-functions.
19605 * eval.c (Fsetq): Handle lexical vars.
19606 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19607 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19608 (FletX, Flet): Obey lexical binding.
19609 (Fcommandp): Handle closures.
19610 (Feval): New `lexical' arg.
19611 (eval_sub): New function extracted from Feval. Use it almost
19612 everywhere where Feval was used. Look up vars in lexical env.
19614 (Ffunctionp): Move from subr.el.
19615 (Ffuncall): Handle closures.
19616 (apply_lambda): Remove `eval_flags'.
19617 (funcall_lambda): Handle closures and new byte-code-functions.
19618 (Fspecial_variable_p): New function.
19619 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19620 but without exporting it to Lisp.
19622 * doc.c (Fdocumentation, store_function_docstring):
19623 * data.c (Finteractive_form): Handle closures.
19625 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19628 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19630 (exec_byte_code): New function extracted from Fbyte_code to handle new
19631 calling convention for byte-code-functions. Add new byte-codes.
19633 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19635 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19637 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19639 * xdisp.c (redisplay_internal): Fix prototype.
19641 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19643 * xdisp.c (SCROLL_LIMIT): New macro.
19644 (try_scrolling): Use it when setting scroll_limit.
19645 Limit scrolling to 100 screen lines.
19646 (redisplay_window): Even when falling back on "recentering",
19647 position point in the window according to scroll-conservatively,
19648 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19650 (try_scrolling): When point is above the window, allow searching
19651 as far as scroll_max, or one screenful, to compute vertical
19652 distance from PT to the scroll margin position. This prevents
19653 try_scrolling from unnecessarily failing when
19654 scroll-conservatively is set to a value slightly larger than the
19655 window height. Clean up the case of PT below the margin at bottom
19656 of window: scroll_max can no longer be INT_MAX. When aggressive
19657 scrolling is in use, don't let point enter the opposite scroll
19658 margin as result of the scroll.
19659 (syms_of_xdisp) <scroll-conservatively>: Document the
19660 threshold of 100 lines for never-recentering scrolling.
19662 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19664 * dispextern.h (move_it_by_lines):
19665 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
19666 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
19667 (message_log_check_duplicate): Remove parameters `prev_bol' and
19668 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19669 (redisplay_internal): Remove parameter `preserve_echo_area',
19670 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19672 * indent.c (Fvertical_motion):
19673 * window.c (window_scroll_pixel_based, Frecenter):
19674 Don't pass `need_y_p' to `move_it_by_lines'.
19676 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19678 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19679 steal a few bits to be more compact.
19680 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19681 Remove unneeded casts.
19683 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19685 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19687 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19688 binding" message (bug#7967).
19690 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19692 Fix more problems found by GCC 4.6.0's static checks.
19694 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19695 Remove unused local var.
19697 * editfns.c (Fmessage_box): Remove unused local var.
19699 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19700 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19701 Omit unused local vars.
19702 * window.c (shrink_windows): Omit unused local var.
19703 * menu.c (digest_single_submenu): Omit unused local var.
19704 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19705 Omit unused local var.
19707 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19708 Don't assume string length fits in int.
19709 (keyremap_step, read_key_sequence): Use size_t for sizes.
19710 (read_key_sequence): Don't check last_real_key_start redundantly.
19712 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19713 instead of alloca (Bug#8344).
19715 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19716 (Fbacktrace_frame): Don't assume nframes fits in int.
19718 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19720 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19723 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19725 * cm.c (calccost): Turn while-do into do-while, for clarity.
19727 * keyboard.c (syms_of_keyboard): Use the same style as later
19728 in this function when indexing through an array. This also
19729 works around GCC bug 48267.
19731 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19733 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19735 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19736 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19738 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19739 This avoids undefined behavior on integer overflow, and is a bit
19740 more convenient anyway since it is compared to a size_t variable.
19742 Variadic C functions now count arguments with size_t, not int.
19743 This avoids an unnecessary limitation on 64-bit machines, which
19744 caused (substring ...) to crash on large vectors (Bug#8344).
19745 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19746 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

19752 (internal_condition_case_n, run_hook_with_args, apply_lambda)
19753 (funcall_lambda, mark_backtrace): Likewise.
19754 * fns.c (concat): Likewise.
19755 * frame.c (x_set_frame_parameters): Likewise.
19756 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19757 0 if not found, not -1. All callers changed.
19759 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19760 (stack_copy_size): Now size_t, not int.
19761 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19763 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19765 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

19769 * lisp.h (multibyte_char_to_unibyte):
19770 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19771 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19777 * xdisp.c (message_dolog, set_message_1): All callers changed.
19779 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
19781 * keyboard.c (safe_run_hook_funcall): New function.
19782 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19783 don't set the hook to nil, but remove the offending function instead.
19784 (Qcommand_hook_internal): Remove, unused.
19785 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19786 Vcommand_hook_internal.
19788 * eval.c (enum run_hooks_condition): Remove.
19789 (funcall_nil, funcall_not): New functions.
19790 (run_hook_with_args): Call each function through a `funcall' argument.
19791 Remove `cond' argument, now redundant.
19792 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
19793 (Frun_hook_with_args_until_failure): Adjust accordingly.
19794 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

19798 * dispextern.h (string_buffer_position): Remove declaration.
19800 * print.c (strout): Remove parameter `multibyte', unused since
19801 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
19803 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
19804 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19805 All callers changed.
19807 * w32.c (_wsa_errlist): Use braces for struct initializers.

19817 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.

19820 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
19822 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

19862 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
19864 * keyboard.c (timer_check): Remove parameter `do_it_now',
19865 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
19866 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
19867 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.

19870 * w32menu.c (w32_menu_display_help):
19871 * xmenu.c (show_help_event, menu_help_callback):
19872 Adjust calls to `show_help_echo'.
19874 * gtkutil.c (xg_maybe_add_timer):
19875 * keyboard.c (readable_events):
19876 * process.c (wait_reading_process_output):
19877 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.

19966 * buffer.c (Fkill_all_local_variables):
19967 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19969 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19970 unconditionally since it does the check itself.
19972 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19974 Fix more problems found by GCC 4.5.2's static checks.
19976 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19977 the first time through the loop, since we know p0 < p1 then.
19978 This also avoids a gcc -Wstrict-overflow warning.
19980 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19981 leading to a memory leak, possible in functions like
19982 load_charset_map_from_file that can allocate an unbounded number
19983 of objects (Bug#8318).
19985 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19986 that could (at least in theory) be that large.
19988 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19989 This is less likely to overflow, and avoids undefined behavior if
19990 overflow does occur. All callers changed. Use strtoul to scan
19991 for the unsigned long integer.
19992 (pint2hrstr): Simplify and tune code slightly.
19993 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19995 * scroll.c (do_scrolling): Work around GCC bug 48228.
19996 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
19998 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
19999 This also avoids a warning with gcc -Wstrict-overflow.

20008 * process.c (Fmake_network_process): Use socklen_t, not int,
20009 where POSIX says socklen_t is required in portable programs.
20010 This fixes a porting bug on hosts like 64-bit HP-UX, where
20011 socklen_t is wider than int (Bug#8277).
20012 (Fmake_network_process, server_accept_connection):
20013 (wait_reading_process_output, read_process_output):

20028 Include tparam.h instead, since it declares them.
20029 * cm.h (PC): Remove extern decl; tparam.h now does this.

20031 * terminfo.c: Include tparam.h, to check interfaces.
20032 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20033 (tparam): Adjust signature to match interface in tparam.h;
20034 this removes some undefined behavior. Check that outstring and len

20085 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20087 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20088 clobbering (Bug#8298).
20089 * sysdep.c (sys_subshell): Likewise.
20090 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20092 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20093 This should get cleaned up, so that child_setup has the
20094 same signature on all platforms.
20096 * callproc.c (call_process_cleanup): Now static.
20097 (relocate_fd): Rename locals to avoid shadowing.
20099 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20101 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20102 not to be necessary, and produces flickering.

20156 to avoid gcc -Wbad-function-cast warning.
20157 Use a different way to cause a compilation error if anyone uses
20158 n rather than nn, a way that does not involve shadowing.
20159 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20161 * deps.mk (unexalpha.o): Remove; unused.

20258 (Fmemory_limit): Cast sbrk's returned value to char *.
20260 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

20268 to use the following functions instead of these macros.
20269 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20270 EMACS_INT, since callers assume the returned value fits in int.
20271 (upcase1): Likewise, for UPCASE_TABLE.
20272 (uppercasep, lowercasep, upcase): New static inline functions.
20273 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20283 (regex_compile, re_match_2_internal): Mark locals as initialized.
20284 (RETALLOC_IF): Define only if needed.
20285 (WORDCHAR_P): Likewise. This one is never needed, but is used
20286 only in a comment talking about a compiler bug, so put inside
20287 the #if 0 of that comment.
20288 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20289 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

20316 New macros, so that the caller can use some names other than
20317 gcpro1, gcpro2, etc.
20318 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20320 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20321 argument, for consistency with GCPRO2_VAR, etc: it is now the
20322 prefix of the variable, not the variable itself. All uses
20324 * dired.c (directory_files_internal, file_name_completion):
20325 Rename locals to avoid shadowing.
20327 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20328 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20329 dired.c's scmp function, had undefined behavior.
20330 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20331 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20332 * buffer.h: ... to here, because these macros use current_buffer,
20333 and the new implementation with inline functions needs to have
20334 current_buffer in scope now, rather than later when the macros
20336 (downcase, upcase1): New static inline functions.
20337 (DOWNCASE, UPCASE1): Reimplement using these functions.
20338 This avoids undefined behavior in expressions like
20339 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20340 from race conditions in accessing the global variables
20341 case_temp1 and case_temp2.
20342 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20343 * lisp.h (case_temp1, case_temp2): Remove their decls.
20344 * character.h (ASCII_CHAR_P): Move from here ...
20345 * lisp.h: ... to here, so that the inline functions mentioned
20346 above can use them.

20353 (file_name_as_directory): Use const pointers when appropriate.
20354 (Fexpand_file_name): Likewise. In particular, newdir might
20355 point at constant storage, so make it a const pointer.
20356 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20357 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20359 (Fset_file_times, Finsert_file_contents, auto_save_error):

20364 to avoid shadowing.
20366 * marker.c (bytepos_to_charpos): Remove; unused.
20368 * lisp.h (verify_bytepos, count_markers): New decls,
20369 so that gcc does not warn that these functions aren't declared.

20372 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20373 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20374 (copy_text): Remove unused local var.

20379 * buffer.c (fix_overlays_before): Mark locals as initialized.
20380 (fix_start_end_in_overlays): Likewise. This function should be
20381 simplified by using pointers-to-pointers, but that's a different
20383 (switch_to_buffer_1): Now static.
20384 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20385 (report_overlay_modification): Rename locals to avoid shadowing.

20388 Fix pointer signedness issue.
20389 (sys_subshell): Mark local as volatile if checking for lint,
20390 to suppress a gcc -Wclobbered warning that does not seem to be right.
20391 (MAXPATHLEN): Define only if needed.
20393 * process.c (serial_open, serial_configure): Move decls from here ...
20394 * systty.h: ... to here, so that they can be checked.
20396 * fns.c (get_random, seed_random): Move extern decls from here ...

20433 if GCC considers string literals to be constants.
20435 * lisp.h (fatal_error_signal): Add decl, since it's exported.
